The first supporting member 20 is perpendicularly fixed to the base 10. The first supporting member 20 defines a first opening groove 21, a receiving slot 22, at least one guiding slot 23, a first through hole 24, and a second through hole 25. The first opening groove 21 is defined by notching the first supporting member 20 a first distance downward to receive a partial of the pivot shaft 40. The receiving slot 22 is arranged between the first opening groove 21 and the second through hole 25. The receiving slot 22 extends along the length of the first supporting member 20. The first supporting member 20 further includes a blade 26. The blade 26 is received in the receiving slot 22, and is capable of moving upward and downward along the receiving slot 22 to cut the adhesive tape. The at least one guiding slot 23 extends along the length of the first supporting member 20. In the embodiment, one guiding slot 23 is employed. The first through hole 24 can receive a part of the driving assembly 50, and the second through hole 25 can receive another part of the driving assembly 50.
The second supporting member 30 is fixed to the base 10 and parallel with the first supporting member 20. The second supporting member 30 defines a second opening groove 31 and a third through hole 32 respectively opposite to the first opening groove 21 and the first through hole 24. The second opening groove 31 is formed by notching the second supporting member 30 a second distance downward. The second opening groove 31 can receive another part of the pivot shaft 40. The third through hole 32 can receive the part of the driving assembly 50.
The pivot shaft 40 can include a shaft 41 and a ring 42. A first end of the shaft 41 is received in the first opening groove 21 through an opening of the first opening groove 21. A second end of the shaft 41 is received in the second opening groove 31 through an opening of the second opening groove 31. The ring 42 protrudes from the peripheral surface of the shaft 41 near the middle of the shaft 41. In a first embodiment, the opposite sides of the ring 42 respectively resist the first supporting member 20 and the second supporting member 30, limiting the pivot shaft 40 between the first supporting member 20 and the second supporting member 30. The adhesive tape coil 200 is pivoted on the ring 42. In the embodiment, the outer diameter of the ring 42 is slightly less than the inner diameter of the adhesive tape coil 200. When an external force pulls an end of the adhesive tape, the adhesive tape coil 200 rotates around the shaft 41. In an alternative embodiment, the outer diameter of the ring 42 is the same as the inner diameter of the adhesive tape coil 200. When the external force pulls the end of the adhesive tape, the adhesive tape coil 200 and the pivot shaft 40 rotate relative to the first supporting member 20 and the second supporting member 30.
The driving assembly 50 can include a drive wheel 51, a handle 52, a drive shaft 53, a secondary shaft 54, a secondary wheel 55, and a drive belt 56. The handle 52 is attached to the drive wheel 51 and can be manually operated. The drive shaft 53 passes through both the third through hole 32 and the first through hole 24 and is fixed in the center of the drive wheel 51. Thus, the drive wheel 51 can be driven to rotate with the handle 52 when an external force is exerted on the handle 52. The secondary shaft 54 passes through the second through hole 25. A first end 541 of the secondary shaft 54 and a second end 542 of the secondary shaft 54 are respectively exterior to the opposite sides of the first supporting member 20. The first end 541 of the secondary shaft 54 is fixed in a hollow of the hollow rod 300. In the embodiment, the first end 541 of the secondary shaft 54 is threaded to the hollow rod 300. The second end 542 of the secondary shaft 54 is fixed in the center of the secondary wheel 55. The secondary wheel 55 and the drive wheel 51 are on the same side of the first supporting member 20. In the embodiment, a size of the secondary wheel 55 is less than the size of the drive wheel 51. The drive belt 56 is looped over the drive wheel 51 and the secondary wheel 55. Thus, when the handle 52 rotates, the drive wheel 51 can rotate with the handle 52, and the secondary wheel 55, the secondary shaft 54, and the hollow rod 300 can rotate with the drive wheel 51 via the drive belt 56.
The positioning member 60 is fixed to the base 10, parallel with the first supporting member 20, and is flush with the second supporting member 30. The positioning member 60 and the first supporting member 20 cooperatively form a space 620 (see
The limiting member 70 is slidably arranged between the first supporting member 20 and the positioning member 60, and spaced a preset distance from the first supporting member 20. The limiting member 70 defines a positioning groove 71 by notching the limiting member 70 a third distance downward. The end of the positioning groove 71 is opposite to the positioning hole 61. At least one latching member 90 passes through at least one sliding slot 62 and is fixed in the limiting member 70. In the embodiment, two latching members 90 are employed. Thus, the limiting member 70 is slidably connected to the positioning member 60 and is capable of sliding upward and downward along the sliding slots 62. In the embodiment, each latching member 90 can be a screw.
The sliding member 80 is also slidably arranged between the first supporting member 20 and the positioning member 60. The sliding member 80 can include an incline surface 81. The incline surface 81 extends along the moving direction of the sliding member 80. The limiting member 70 is above the sliding member 80 and contacts the inclined surface 81. At least one latching member 90 passes through the guiding slot 23 and is fixed in the sliding member 80. Thus, the sliding member 80 is capable of sliding along the guiding slot 23 into or out off the space 620. In the embodiment, the sliding member 80 is capable of sliding forward and backward along the sliding slots 62.
When winding the hollow rod 300 with the adhesive tape of the adhesive tape coil 200, the sliding member 80 is pushed to move along the guiding slot 23 into the space 620, the sliding member 80 can exert an upward force to the limiting member 70 via the incline surface 81, and the limiting member 70 can move upward until the hollow rod 300 passes through the positioning groove 71. Then, fix the end of the adhesive tape of the adhesive tape coil 200 to the hollow rod 300 and rotate the handle 52, the drive wheel 51 can rotate with the handle 52. The secondary wheel 55, the secondary shaft 54, and the rod 300 can rotate with the drive wheel 51 via the drive belt 56. Thus, the adhesive tape of the adhesive tape coil 200 can be wound to the hollow rod 300 to form an adhesive ring, and the adhesive can be formed on the outer surface of the adhesive ring. Simultaneously, the wound adhesive tape can be sandwiched between the limiting member 70 and the first supporting member 20. Thus, the limiting member 70 and the first supporting member 20 can cooperatively limit the wound adhesive tape, and avoid an incorrect winding (see
When removing the wound adhesive tape, the blade 26 is moved to cut the adhesive tape. The sliding member 80 is pulled to move along the guiding slot 23 out of the space 620. The incline surface 81 of the sliding member 80 can disengage from the limiting member 70. The limiting member 70 can slide downward along the sliding slots 62 with gravity of the limiting member 70 until the limiting member 70 disengages from the wound adhesive tape. Thus, the hollow rod 300 can be taken away from the first end 541 of the secondary shaft 54 (see
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments of the present disclosure.
