FIELD OF THE INVENTION
The present invention relates to a stationery machine which allows adjusting a distance between a first pressing roller and a second pressing roller so as to cooperate with a first cutter template and a second cutter template in different thicknesses and to roll the first cutter template and the second cutter template by ways of the first pressing roller and the second pressing roller, thus cutting various patterns on a paper and adjusting a rolling thickness.
BACKGROUND OF THE INVENTION
Referring to FIG. 1, a conventional stationery machine 10 is used to cut various patterns on a paper in a rolling manner so that children may play different patterns of papers by matching with cutter templates with different patterns. The conventional stationery machine 10 contains a frame 11 having two side plates 111, a crank 12 axially connected on one of the two side plates 111 for driving a first pressing roller 14, a transmission gear 13 disposed on a first end of the first pressing roller 13, a second pressing roller 15 fixed between the two side plates 111 under the first pressing roller 14, and a driven gear 16 fixed on a first end of the second pressing roller 15 for meshing with the first pressing roller 14. In addition, between the first pressing roller 13 and the second pressing roller 15 is defined a distance to input the cutter templates, such that the first pressing roller 13 and the second pressing roller 15 allow cutting different patterns on the paper in the rolling manner.
With reference to FIG. 2, the cutter templates have two different thicknesses. For example, each of a plurality of first cutter templates 20A has a large flat surface and thickness, a first cutting pattern area 201A, and a first foam layer 202A higher than the first cutting pattern area 201A formed around the first cutting pattern area 201A, such that when a first paper 21A is placed over the first form layer 202A, a first upper clamping sheet 22A and a first lower clamping 23A are used to press the plurality of first cutter templates 20A and the first paper 21A, thereafter the plurality of first cutter templates 20A and the first paper 21A are placed into the stationery machine 10 so as to cut the patterns on the first paper 21A. Besides, each of a plurality of second cutter templates 20B has a small flat surface and thickness, a second cutting pattern area 201B, and a second foam layer 202B higher than the second cutting pattern area 201B formed around the second cutting pattern area 201B, such that when a second paper 21B is placed over the second form layer 202B, a second upper clamping sheet 22B and a second lower clamping sheet 23B are used to press the plurality of second cutter templates 20B and the second paper 21B, thereafter the plurality of second cutter templates 20B and the second paper 21B are placed into the stationery machine 10 so as to cut patterns on the second paper 21B.
As shown in FIGS. 2 and 3, because between the first pressing roller 13 and the second pressing roller 15 is defined the distance, when the first cutter templates 20A is applied to cut the patterns, the first upper clamping sheet 22A and the first lower clamping sheet 23A are served to match with the distance between the first pressing roller 13 and the second pressing roller 15. As the second cutter templates 20B is applied to cut the patterns, the second upper clamping sheet 22B and the second lower clamping sheet 23B are served to match with the distance between the first pressing roller 13 and the second pressing roller 15.
Therefore, the first cutter templates 20A and the second cutter templates 20B in different thicknesses have to cooperate with the first upper clamping sheet 22A, the second upper clamping sheet 22B, the first lower clamping sheet 23A, and the second lower clamping 23B, thus causing an using inconvenience.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

Referring further to FIGS. 5-7, the machine body includes a frame 32 having a first side plate 321 and a second side plate 322 between which a first pressing roller 34 is fixed, and a crank set 33 disposed on the first side plate 321 to drive the first pressing roller 34. In this embodiment, the first pressing roller 34 has a first rotary shaft 341, two ends of which have two first bearing sets 342, 343, wherein the two first bearing sets 342, 343 are connected with the first side plate 321 and the second side plate 322, and the first pressing roller 34 has at least two transmission gears in different sizes secured on a first end of the first rotary shaft 341. In this embodiment, a first transmission gear 35 with a large diameter and a second transmission gear 36 with a small diameter are disposed on the first end of the first rotary shaft 341. To drive the first pressing roller 34, in this embodiment, the crank set 33 has an input stem 331 axially connected thereon, a driving gear 332 fixed on a first end of the input stem 331 for meshing with the first transmission gear 35, and a rotatable handle 333 mounted on a second end of the input stem 331 so that as rotating the rotatable handle 333, the driving gear 332 is driven to actuate the first transmission gear 35, and then the first transmission gear 35 drives the first pressing roller 34 to rotate. The first side plate 321 and the second side plate 322 have a first elongated slot 323 and a second elongated slot 324 defined on two lower sides thereof below the first pressing roller 34 so as to insert a second pressing roller 37. In this embodiment, the second pressing roller 37 has a second rotary shaft 371, two ends of which have two second bearing sets 372, 373, wherein the two second bearing sets 372, 373 are placed in the first elongated slot 323 of the first side plate 321 and the second elongated slot 324 of the second side plate 322. To avoid the first pressing roller 34 and the second pressing roller 37 from moving horizontally, in this embodiment, the first side plate 321 has a first stopping piece 325 mounted on an outer surface thereof, and the second side plate 322 has a second stopping piece 326 mounted on an outer surface thereof. The second rotary shaft 371 of the second pressing roller 37 has a driven gear 38 disposed on a first end thereof for moving axially and an adjusting mechanism 39 secured on the first end thereof for adjusting the driven gear 38 to correspond to the first transmission gear 35 and the second transmission gear 36 in different sizes. In this embodiment, the adjusting mechanism 39 has a first spring 391 fitted on the second rotary shaft 371, a first recess 392 and a second recess 393 defined at a predetermined position of the second rotary shaft 371, a sleeve 394 fitted onto the second rotary shaft 371, wherein the sleeve 394 has a retainer 396 mounted therein and abutted by a second spring 395, the retainer 396 has a through hole 3961, a diameter of which is larger than the second rotary shaft 371, and the retainer 396 also has a stop rim 3962 defined under the through hole 3961 so that when the sleeve 394 is pushed, the driven gear 38 is driven to axially move along the second rotary shaft 371 so as to correspond to the first transmission gear 35 or the second transmission gear 36 in different sizes. When the driven gear 38 corresponds to the first transmission gear 35, the retainer 396 is abutted by the second spring 395 so that its stop rim 3962 retains in the first recess 392, thus positioning the driven gear 38. Or when the driven gear 38 corresponds to the second transmission gear 36, the retainer 396 is abutted by the second spring 395 so that the stop rim 3962 retains in the second recess 393, thus positioning the driven gear 38. And when desiring to release the positioning of the driven gear 38, the retainer 396 is pressed so that the stop rim 3962 of the retainer 396 disengages from the first recess 392 or the second recess 393, such that the driven gear 38 allows being moved adjustably. To adjust a distance between the first pressing roller 34 and the second pressing roller 37 and to mesh the driven gear 38 with the first transmission gear 35 or the second transmission gear 36, an abutting mechanism 40 is provided under the second pressing roller 37 so that the second pressing roller 37 is biased by the abutting mechanism 40 to move upwardly and downwardly. The abutting mechanism 40 includes a rotating rod 401 axially connected with the first side plate 321 and the second side plate 322, a first biasing slice 402 and a second biasing slice 403 fixed on two ends of the rotating rod 401, and a profile of the first biasing slice 402 is the same as that of the second biasing slice 403, the first biasing slice 402 has a first top rim 4021 and a first cam face 4022, the second biasing slice 403 has a second top rim 4031 and a second cam face 4032. The abutting mechanism 40 also includes an actuating slice 404 fitted on one of the two ends of the rotating rod 401 adjacent to the second side plate 322 so that after the actuating slice 404 is rotated, the rotating rod 401 is driven by the actuating slice 404 to further drive the first biasing slice 402 and the second biasing slice 403 to rotate, and then the first cam face 4022 of the first biasing slice 402 and the second cam face 4032 of the second biasing slice 403 push the two second bearing sets 372, 373 of the second rotary shaft 371 so that the two second bearing sets 372, 373 are retained by the first top rim 4021 and the second top rim 4031, such that the second pressing roller 37 is moved upwardly to adjust the distance between the first pressing roller 34 and the second pressing roller 37, and the driven gear 38 meshes with the second transmission gear 36.
