Description

Technical Field

[0001] This utility model relates to the field of discard sticker production technology, specifically a winding and slitting device for discard sticker production. Background Technology

[0002] Disposal stickers for diapers are adhesive strips used to roll up diapers after use to prevent leakage of excrement.

[0003] According to the patent titled "Disposable Adhesive Strip Cutting Device" (patent publication number: CN210437565U, patent publication date: 2020-05-01), the device includes a support panel. From top to bottom, the support panel is equipped with a compaction roller assembly, an adsorption roller assembly, and a cutter roller assembly. The adsorption roller assembly includes a first rotating shaft and an adsorption roller mounted on the first rotating shaft to adsorb and hold the disposable adhesive strips. The cutter roller assembly includes a second rotating shaft and a cutter roller mounted on the second rotating shaft, with a cutter mounted on the cutter roller to cut the disposable adhesive strips in conjunction with the adsorption roller. The compaction roller assembly includes a third rotating shaft and a rotating wheel frame mounted on the third rotating shaft. Two horizontally arranged compaction rollers are symmetrically mounted on the rotating wheel frame. The compaction rollers cooperate with the adsorption roller to press the cut disposable adhesive strips firmly onto the diaper. The adsorption roller transfers the cut disposable adhesive strips, effectively preventing them from falling off; simultaneously, the compaction roller and adsorption roller work together to compress the product and the disposable adhesive strips, ensuring the cut disposable adhesive strips adhere firmly to the diaper.

[0004] Based on the aforementioned existing technology, current winding and slitting devices for discarded sticker production still have the following problems: when producing discarded stickers of different widths, operators must manually adjust the positions of multiple cutters on the cutter shaft one by one. This process involves loosening screws, measuring and positioning with calipers, tightening screws, and then re-inspecting. The more blades there are, the longer the adjustment time becomes, and the more prone it is to errors. Therefore, this utility model provides a winding and slitting device for discarded sticker production. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5This utility model provides a technical solution: A winding and slitting device for producing discarded stickers includes a winding mechanism 1, and a slitting mechanism 2 is disposed above the winding mechanism 1 for adjusting the distance between the cutters. The slitting mechanism 2 includes: The lifting unit 21 is located above the winding mechanism 1 and is used to realize the up and down movement of the cutter; The co-location unit 22 is located above the lifting unit 21 and includes a shearing frame 225. A fixed blade 228 is rotatably mounted below the middle hinge point of the shearing frame 225. End frames 226 are mounted at both ends of the shearing frame 225. Sliding blades 227 are rotatably mounted below the left and right hinge points of the shearing frame 225 and below the hinge points of the end frames 226. The fixed blade 228 is fixed to the lifting unit 21. The sliding blade 227 and the fixed blade 228 move synchronously and at the same distance through the shearing and folding of the shearing frame 225 and the end frames 226.

[0018] In this embodiment, the lifting unit 21 includes a fixed frame 211. Rollers 212 are rotatably mounted on the columns inside the fixed frame 211. A set of limiting posts 213 are fixedly mounted on the front and rear sides of the top of the fixed frame 211. Sliding blocks 217 are slidably mounted on the surface of the limiting posts 213. A fixed post 218 is fixedly mounted on the inner side of the sliding block 217. A fixed blade 228 is fixedly mounted on the fixed post 218, and a sliding blade 227 is slidably mounted on the fixed post 218.

[0019] By sliding the sliding block 217 along the limiting post 213 and fixing the fixed post 218, the fixed blade 228 is reliably positioned and the sliding blade 227 is adjusted, ensuring that the cutter is accurately positioned and runs smoothly during the slitting process, thereby improving the slitting accuracy and the overall rigidity of the equipment.

[0020] In this embodiment, a top block 214 is fixedly installed on the top of the limiting post 213, a servo motor 216 is fixedly installed on the top of the top block 214, and a lead screw 215 is fixedly installed through the top block 214 at the output end of the servo motor 216. The lower end of the lead screw 215 is rotatably installed on the fixing frame 211, and a sliding block 217 is threadedly rotatably installed on the surface of the lead screw 215.

[0021] The top block 214, servo motor 216, and lead screw 215 installed on the top of the limiting post 213 constitute the driving and lifting mechanism of the cutter. The effect is that the servo motor 216 drives the lead screw 215 to rotate, which drives the sliding block 217 to move up and down along the lead screw 215, thereby realizing the smooth lifting of the entire slitting mechanism 2, accurately controlling the contact pressure between the cutter and the roll material, adapting to different slitting process requirements, and improving the degree of automation and slitting quality.

[0022] In this embodiment, the same-distance unit 22 further includes a set of fixing blocks 221 fixedly installed on the front and rear end surfaces of the fixing column 218. A half-thread column 222 is fixedly installed on the inner side of the fixing block 221. A moving block 224 is slidably installed on the front end of the half-thread column 222. The bottom end of the moving block 224 is rotatably installed at the hinge point with the front end frame 226 of the shearing frame 225. A threaded sleeve 223 is rotatably installed on the front side of the moving block 224. The threaded sleeve 223 is rotatably installed on the threaded surface on the front side of the half-thread column 222.

[0023] By rotating the threaded sleeve 223, the moving block 224 is pushed to move along the half thread column 222, which in turn drives the shearing frame 225 and the end frame 226 to achieve shearing and folding motion. This allows the sliding blade 227 to be adjusted synchronously and equidistantly relative to the fixed blade 228, greatly improving the efficiency and accuracy of blade distance adjustment and adapting to the production needs of multi-specification discard stickers.

[0024] In this embodiment, the winding mechanism 1 includes a frame 11, an unwinding module 12 is provided on the upper right side of the frame 11, an auxiliary wheel module 13 is symmetrically installed inside the frame 11, a top wheel module 14 is provided on the upper left side of the frame 11, a winding frame 15 is fixedly installed on the left side of the frame 11, and a winding module 16 is provided on the inner side of the winding frame 15.

[0025] The frame 11, unwinding module 12, auxiliary wheel module 13, top wheel module 14, winding frame 15, and winding module 16 constitute a complete roll material conveying path, ensuring the continuous and stable operation of the roll material from unwinding, through multiple sets of rollers 212 for guidance, slitting, and finally winding, thereby improving overall production efficiency and the synergy of the slitting process.

[0026] In this embodiment, the roll material to be processed on the unwinding module 12 passes under the right auxiliary wheel module 13 inside the frame 11, and is wound in an inverted V shape onto three sets of rollers 212. It then passes under the left auxiliary wheel module 13 inside the frame 11 and is wound onto the take-up module 16 above the top wheel module 14.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, the roll material to be processed on the unwinding module 12 passes under the right auxiliary wheel module 13 inside the frame 11 and is wound in an inverted V shape onto the three sets of rollers 212. It also passes under the left auxiliary wheel module 13 inside the frame 11 and is wound onto the take-up module 16 above the top wheel module 14. Next, the user rotates the threaded sleeve 223 to push and pull the moving block 224. The moving block 224 drives the shearing frame 225 and the end frame 226 to shear, contract and expand, which in turn drives the sliding blades 227 on the left and right sides of the fixed blade 228 to move synchronously and equidistantly. Then, the two servo motors 216 drive the lead screw 215 to rotate, and the lead screw 215 drives the sliding block 217 to move up and down synchronously. The sliding block 217 drives the same distance unit 22 to move up and down synchronously through the fixed column 218, so that the fixed knife 228 and the sliding knife 227 contact the coil. When the coil moves, the fixed knife 228 and the sliding knife 227 cut the coil.
