The two groups of traction rollers 112 and unfolding rollers 113 are arranged in parallel with the feeding roller 110. A material guiding restraining tube 1111 is arranged between the two groups of material guiding rollers 111. The cross section of the material guiding restraining tube 1111 is rectangular and arranged vertically.
[0038] When the gasket raw material is guided, two groups of traction rollers 112 are arranged at the outlet of the feed roller 110 to guide the gasket raw material, and then the unfolding roller 113 is used to flatten the gasket raw material to ensure that the gasket raw material is pulled out from the guide constraint tube.
[0039] The upper end of the pipe outlet 1111 is led out, and the two sets of guide rollers 111 are started to rotate to implement the operation of leading out the gasket raw material at equal distances, so as to achieve equal thickness cutting of the gasket to form qualified gasket raw material and ensure the accuracy of fixing the gasket and the packaging film.

[0043] Specifically, a driven gear 1114 is disposed at one end of the material guide roller 111, and the driven gear 1114 is meshed with a driving gear 1115, and the driving gear 1115 is rotatably disposed on a frame and connected to a driving motor 1116, and the frame is connected to a slider.
[0044] In order to guide the gasket raw materials in equal length, an opening is provided on the tube wall of the material guide constraint tube 1111, and a guide belt 1117 is provided in the opening.

The clamping slide bar 11171 is horizontally and slidably arranged on the clamping frame, and a clamping spring 11172 is sleeved on one end of the clamping slide bar 11171 extending from the clamping frame.
[0045] The clamping spring 11172 is utilized to realize elastic clamping of the guide belt 1117, thereby implementing equal-length lead-out of the gasket raw material, so as to implement stable and reliable guiding of the gasket raw material.
[0046] Furthermore, the tube cutting unit includes a first cutter 121 and a second cutter 122 arranged beside the tube opening at the upper end of the material guiding and restraining tube 1111.

When the hole towel is actually used, one end of the gasket is wavy. Or zigzag, when the gasket fits against the patient's abdomen, body fluids or blood are led out into the hole towel from the gap between the wavy end surface of the gasket and the belly nail clippers to ensure the effective use of the hole towel.

[0055] As the pushing cylinder 1246 is started, the pushing frame 1244 moves horizontally, thereby causing the pushing slot wall 1243 to move horizontally, thereby causing the pushing slot wall 1243 to move horizontally along the upper plate surface of the first cutter 121. When the material blocking head 1249 abuts against the baffle plate 1248 and compresses the avoidance spring 1247 to overcome the first torsion spring 1242 of the movable slot wall 1241, the gasket is guided out of the material receiving slot plate 124, thereby realizing the horizontal pushing out of the gasket.
