[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model solves the problem that since the types of self-adhesive processed each time are different, the hollow diameter in the middle of the object is different after being rolled up and the size of the feeding rod cannot be adjusted quickly, resulting in problems in material transmission. This is achieved by setting a first bidirectional threaded rod and a connecting plate. When the motor is started, the connecting shaft rotates to drive the first bidirectional threaded rod to rotate. The first bidirectional threaded rod pushes two first sliders to move and approach each other. The movement of the first sliders pushes the hollow rod to rotate around the first positioning block. Due to the length of the hollow rod itself, the connecting plate is pushed outward. That is, the rotation of the first bidirectional threaded rod drives the first sliders to move, and then drives the hollow rod to push the connecting block to extend outward.

[0017] 2. The utility model solves the problem that since the types of self-adhesive are different, their thicknesses are inconsistent, and when the blade cuts, it may not be able to completely separate the self-adhesive due to its excessive thickness, resulting in poor processing effects. This is achieved by setting a second bidirectional threaded rod and a connecting rod. The rotation of the second bidirectional threaded rod pushes multiple connecting blocks to move. While the connecting blocks push the connecting rod to move, they also push the second positioning block to move. The second positioning block pushes the positioning frame to slide upward, driving multiple cutting blades to partially extend out of the placement plate, thereby cutting the object above the placement plate into strips. That is, when the connecting rod is pushed by the second positioning block, it pushes the positioning frame upward, and the positioning frame extends multiple blades outward.

[0018] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The outer wall of the second positioning block 310 is slidably connected to the inner wall of the placing plate 307. The outer wall of the second positioning block 310 is fixedly connected to a positioning frame 311. During the movement of the connecting block 308, it will push the connecting rod 309 to move while the connecting rod 309 rotates around the connecting block 308, thereby pushing the second positioning block 310 to move while pushing the positioning frame 311 to move.

[0032] A specific application of this embodiment is:

[0033] When the staff needs to use the device, put the adhesive tape roll on the outside of the connecting plate 207, and then start the motor 201 to drive the connecting shaft 202 to rotate while driving the first bidirectional threaded rod 203 to rotate. The first bidirectional threaded rod 203 is used to push two first sliders 204 to move and approach each other. The movement of the first sliders 204 pushes the hollow rod 205 to rotate around the first positioning block 206. Due to the length of the hollow rod 205, it pushes the connecting plate 207 to move outward. Multiple sliding rods 214 are used to stabilize the movement of the connecting plate 207, and the connecting plate 207 pulls the spring 215 outside the sliding rod 214. The elasticity of the spring 215 is used to relieve the pressure of the object on the connecting plate 207. The movement of the connecting plate 207 drives the second slider 210 to move and drives the support rod 211 to move at the same time. Since the other end of the support rod 211 is restricted inside the hollow rod 205 by the third slider 212, when the connecting plate 207 moves, the support rod 211 will pull the second slider 210 to slide along the limit groove 208, and the third slider 212 at the other end will slide along the inside of the hollow rod 205. The movement of the second slider 210 squeezes the resistance spring 209 inside the limit groove 208, and the elasticity of the resistance spring 209 is used to increase the supporting force of the support rod 211 on the connecting plate 207. Subsequently, during the rotation of the first bidirectional threaded rod 203, it drives the first pulley 301 to rotate and uses the transmission of the first belt 302, so that the first pulley 301 drives the double-layer pulley 303 at the other end to rotate. Another second belt 305 is connected inside the double-layer pulley 303. The transmission of this second belt 305 is used to drive the second pulley 304 to rotate. At the same time, two second bidirectional threaded rods 306 are connected to the outside of the double-layer pulley 303 and are wrapped by the placing plate 307, so as to prevent the second bidirectional threaded rods 306 from being exposed outside. The rotation of the second bidirectional threaded rods 306 pushes multiple connecting blocks 308 to move, and the connecting blocks 308 push the connecting rod 309 to move while pushing the second positioning block 310 to move. The second positioning block 310 pushes the positioning frame 311 to slide upward while driving multiple cutting blades 312 to make a part of them extend out of the placing plate 307, so as to cut the object above the placing plate 307 into strips. Finally, the winding wheel 102 is used to wind up the cut materials. During the movement of the connecting rod 309, it drives the second positioning rod 314 to move and pulls the limit block 315 to slide along the inside of the limit plate 316 with many functions, and the limit block 315 pulls the pressure spring 317 inside the limit plate 316. The elasticity of the pressure spring 317 is used to relieve the pressure of the limit block 315. During the movement of the limit block 315, it drives the first positioning rod 313 to rotate around the connecting block 308, so as to thermally stabilize the moving speed of the limit block 315.
