BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a cutting structure and, more particularly, to a measurement structure which is adapted for a curtain cutting machine by which an extending length of a curtain is controlled to cut the curtain.
Description of the Prior Art
A curtain is applied to shield a window and to decorate a house/room, and it is produced in various sizes and is cut by a curtain cutting machine based on using requirements.
Referring to FIGS. 12 and 13, a conventional curtain cutting machine contains a working table 10 on which a clamping apparatus 20, a cutting device 30, and a measuring device 40 are arranged. The cutting device 30 is disposed on and contacts with an outer surface of the clamping apparatus 20. The measuring device 40 is mounted on an outer surface of the cutting device 30 and includes a movable stop member 401 and a scale set 402 fixed on one side thereof. When cutting a curtain, the movable stop member 401 of the measuring device 40 is adjusted toward a desired cutting position relative to the scale set 402, one end of the curtain 50 extends through the clamping apparatus 20 to contact with the movable stop member 401 of the measuring device 40, and the clamping apparatus 20 clamps the curtain 50 so that the curtain 50 is cut by the cutting device 30, thus changing a width of the curtain 50.
However, when the one end of the curtain 50 contacts with the movable stop member 401 of the measuring device 40 and the clamping apparatus 20 clamps the curtain 50, the curtain 50 is interfered, and cut scraps get stuck between the cutting device 30 and the movable stop member 401 of the measuring device 40, so the cut scraps have to be removed manually or by using a tool. Furthermore, the measuring device 40 is mounted on the outer surface of the cutting device 30, so the conventional curtain cutting machine is too large to be fixed in a limited space.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a measurement structure in which a covering door stops an opening of a cutting device, a scale set is configured to indicate a position of a slidable seat, and the slidable seat drives a curtain to extend out of the opening in a predetermined length, so the curtain is not interfered by the curtain cutting machine and is cut easily and quickly.
Another objective of the present invention is to provide a measurement structure in which the covering door stops the opening, the slidable seat slides along the track, and the scale set measures a movement of the slidable seat, so a size of the curtain cutting machine is small, thus fixing the curtain cutting machine in a limited space and using the curtain cutting machine conveniently.
To obtain above-mentioned objectives, a measurement structure provided by the present invention is adapted for a curtain cutting machine and contains: a track, a slidable seat, a scale set, a cutting device, and a covering cover.
The track includes a front segment and a rear segment.
The slidable seat is disposed on and slides along the track, and the slidable seat includes a clamping apparatus.
The scale set is secured on the track to indicate a position of the slidable seat.
The cutting device is located adjacent to the front segment of the track and includes an opening.
The covering door is mounted between the cutting device and the track and moves between a first position and a second position. When the covering door slides to the first position, it stops the opening of the cutting device, and when the covering door slides to the second position, it opens the opening of the cutting device.
Preferably, a curtain is placed on the track and its one end is biased against the covering door. Thus, the slidable seat slides along the track and indicates its position by way of the scale set, the clamping apparatus clamps the curtain, the covering door is moved and the slidable seat drives the curtain to extend out of the opening of the cutting device in a predetermined length to cut the curtain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustration only, the preferred embodiments in accordance with the present invention.
With reference to FIGS. 1 to 3, a measurement structure according to a preferred embodiment of the present invention is adapted for a curtain cutting machine, and the curtain cutting machine comprises: a base 1 on which a track 2, a slidable seat 3, a scale set 4, a cutting device 5, and a covering door 6 are arranged. The track 2 includes a front segment 21 and a rear segment 22. The slidable seat 3 is disposed on and slides along the track 2, and the slidable seat 3 includes a positioning apparatus 31 mounted on one side thereof and configured to fix the slidable seat 3. The slidable seat 3 also includes a clamping apparatus 32 fixed thereon, and the scale set 4 is secured on the track 2 to indicate a position of the slidable seat 3. The cutting device 5 is located adjacent to the front segment 21 of the track 2 and includes a cutter 51 and an opening 52 configured to insert a curtain. The covering door 6 is mounted between the cutting device 5 and the track 2 and includes a stop face 61 facing to the track 2, and the stop face 61 has a grip portion 62 configured to be held and pulled by a user to move the covering door 6. The covering door 6 also includes two guiding rails 63, and each guiding rail 63 is arranged on each of two sides of the covering door 6. The two guiding rails 63 are applied to slide the covering door 6 to a first position A1 and a second position A2. When the covering door 6 slides to the first position A1, it stops the opening 52 of the cutting device 5, and when the covering door 6 slides to the second position A2, it opens the opening 52 of the cutting device 5.
Between the stop face 61 of the covering door 6 and the cutter 51 defines a spacing distance X1. When the slidable seat 3 slides toward a front-most position, between the slidable seat 3 and the scale set 4 defines a compensation distance Y1, and the compensation distance Y1 is equal to the spacing distance X1.
When cutting the curtain, as shown in FIGS. 4 and 5, the slidable seat 3 slides toward a predetermined position based on a desired cutting length of the curtain 7 by collating with the scale set 4. For example, when desiring to cut the curtain 7 to 5.5 cm, the slidable seat 3 slides to an indication position of 5.5 cm on the scale set 4 by collating with the scale set 4. The covering door 6 is manually moved to the first position A1 to stop the opening 52 of the cutting device 5. As illustrated in FIG. 6, the positioning apparatus 31 is locked to cut the curtain of fixed size continuously, and the slidable seat 3 contacts with the positioning apparatus 31 and fixes quickly. Referring to FIGS. 7 and 9, the curtain 7 is rolled and placed on the track 2. One end of the curtain 7 is biased against the stop face 61 of the covering door 6. After the clamping apparatus 32 clamps the curtain 7. As illustrated in FIGS. 10 and 11, the covering door 6 is manually moved to the second position A2 to open the opening 52 of the cutting device 5, and the slidable seat 3 drives the curtain 7 to slide toward the front-most position along the track 2 so that the curtain 7 extends out of the opening 52 of the cutting device 5 in a predetermined length. Due to the compensation distance Y1 offsetting against the spacing distance X1 between the stop face 61 of the covering door 6 and the cutter 51, the curtain 7 extends out of the opening 52 of the cutting device 5 in the predetermined length. The predetermined length of the curtain 7 extending out of the opening 52 is identical to the desired cutting length of the curtain 7, so the curtain 7 is cut in the predetermined length by the cutter 51.
Furthermore, the covering door 6 is moved toward the first position A1 and the second position A2 in a pneumatic driving manner or an electric driving manner.
Accordingly, the measurement structure of the present invention contains advantages as follows:
1. The covering door 6 stops the opening 52, the scale set 4 measures a movement of the slidable seat 3, and the slidable seat 3 drives the curtain 7 to extend out of the opening 52 in the predetermined length. Thus, the curtain 7 is not interfered by the curtain cutting machine, and cut scraps of the curtain 7 drop smoothly, thus cutting the curtain 7 easily and quickly.
2. The covering door 6 stops or opens the opening 52, the slidable seat 3 slides along the track 2, and the scale set 4 measures the movement of the slidable seat 3. Thus, a size of the curtain cutting machine is small, thus fixing the curtain cutting machine in a limited space and using the curtain cutting machine conveniently.
While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
