Description

Technical Field

[0001] This invention relates to the field of paper recycling technology, specifically to a device for recycling self-adhesive label paper waste. Background Technology

[0002] During the slitting process of self-adhesive label rolls, they need to be cut to a set width. This process generates continuous long strips of waste material on both sides of the roll. This type of waste material is characterized by its thinness, light weight, static electricity on the surface, and easy adhesion of the adhesive backing. It is a typical process byproduct of self-adhesive label production.

[0003] Currently, the industry's slitting equipment generally adopts an open free discharge structure for handling side waste. That is, after the waste is separated by the slitting blade, it is directly discharged naturally from the discharge channel without any restraint or collection structure. It is naturally scattered and piled up randomly on the ground around the equipment, which is a rough discharge mode.

[0004] The existing material discharge method has obvious technical defects: First, the waste material is scattered in long strips, which requires manual sorting and bagging, which is labor-intensive, costly and inefficient. Second, the long strips of waste material are piled up in a messy manner. The waste material is thin and static electricity, which makes it easy to fly and adhere to equipment components, affecting the stable operation of the equipment and posing a safety risk of entanglement. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 In existing technologies, the conventional discharge method for long strips of waste generated during the slitting of self-adhesive labels is as follows: after being cut by the slitting knife, the waste is directly discharged through a simple discharge pipe without any guiding constraints or collection structure, and naturally scatters and accumulates randomly on the ground around the equipment. This method relies entirely on manual processing, requiring manual picking, sorting, and collection of the randomly accumulated long strips of waste, followed by manual bagging and transportation. This method has a low degree of automation and requires a large amount of manual intervention.

[0022] like Figure 1 As shown, this embodiment has a waste collection device 200 on the side of the self-adhesive slitting device 100 for collecting waste discharged from the discharge pipe, specifically as follows: Figure 3 As shown, the waste collection device 200 includes a connecting pipe 201, a negative pressure chamber 202, a negative pressure mechanism 203, and a connecting plate 204, wherein the connecting pipe 201 is sleeved outside the discharge pipe of the self-adhesive slitting device 100, as shown. Figure 9As shown, the negative pressure chamber 202 also includes a cutting chamber 221, within which a knife holder 223 is fixedly mounted and a cutting tool 220 is slidably mounted. Figure 10 As shown, a negative pressure suction tube 217 is provided inside the cutting chamber 221. One end of the negative pressure suction tube 217 is located near the bottom of the cutting chamber 221, and the other end is located above the cutting chamber 221 and communicates with the negative pressure chamber 202. The negative pressure mechanism 203 is located at the top of the negative pressure chamber 202, and the inside of the negative pressure chamber 202 is cylindrical. Figure 9 As shown, the negative pressure chamber 202 is also provided with an outlet 216, and the connecting plate 204 is rotatably disposed at the outlet 216 end of the negative pressure chamber 202. The connecting plate 204 is used to fix woven bags or other bags for collecting waste.

[0023] The working principle of the waste collection device 200 is as follows: Figure 10 As shown, during use, the connecting pipe 201 is fixed inside the discharge pipe by the magnetic ring 208 or bolts, completely encasing the discharge pipe. The waste generated during cutting enters the cutting chamber 221. The blade 220 inside the cutting chamber 221 moves and cooperates with the blade holder 223 to shred the waste. The shredded waste falls to the bottom of the cutting chamber 221 and is sucked into the negative pressure chamber 202 through the negative pressure suction pipe 217. Since the negative pressure chamber 202 is cylindrical, the negative pressure mechanism 203 creates a stable, high-speed spiral vortex in the circular cross-section. The airflow continuously rotates along the cylinder wall, causing the cut waste to spiral downwards. Finally, the waste enters the woven bag on the connecting plate 204 through the outlet 216 for collection. A removable discharge trough 214 is provided at the bottom of the negative pressure chamber 202. It should be emphasized that the core improvement of this embodiment lies in the following: This device is fixed to the equipment discharge pipe by magnetic attraction or bolts, making installation and disassembly convenient. It can be directly connected to the existing discharge structure, demonstrating strong versatility. The device has a built-in shredding mechanism composed of blades and blade holders, which can cut continuous long strips of waste into short pieces online, effectively preventing long strips of waste from tangling and clogging the pipeline, and also facilitating material conveying, stacking, and transfer. The cylindrical negative pressure chamber can form a stable high-speed spiral vortex under the action of the negative pressure mechanism. The airflow rotates regularly along the cylinder wall and drives the material downward in an orderly manner. The flow field is uniform and without dead corners, significantly reducing the probability of material retention and blockage, and ensuring continuous and smooth conveying.

[0024] The entire system utilizes negative pressure for material conveying and employs woven bags for centralized collection, replacing manual picking, sorting, and bagging operations. This reduces labor intensity and production costs while preventing waste scattering and static adhesion, thus improving the workshop working environment. This device integrates chopping, cyclone conveying, and centralized collection functions. Its compact structure and small footprint make it suitable for confined installation conditions. It operates stably, is easy to maintain, and demonstrates outstanding practicality.

[0025] It should be noted that the specific structures of the cutting tool 220 and the tool holder 223 are as follows, such as... Figure 9 As shown, the top of the cutter 220 is equipped with a drive box 213, and a reciprocating screw 222 is rotatably mounted inside the drive box 213. The cutter holder 223 is fixedly installed in the cutting chamber 221. The top of the cutter 220 slides in engagement with the drive box 213, while the cutter 220 is threadedly engaged with the reciprocating screw 222. That is, the rotation of the reciprocating screw 222 realizes the reciprocating movement of the cutter 220. The cutter 220 and the cutter holder 223 cooperate to shred the waste material, such as... Figure 4 As shown, a rotating wheel is provided at the air inlet of the negative pressure mechanism 203. When the negative pressure mechanism 203 is activated, it drives the rotating wheel to rotate. A first connecting shaft 210 is coaxially and fixedly provided on the rotating wheel. A first pulley 211 is coaxially and fixedly provided on both the first connecting shaft 210 and the reciprocating screw 222. A first synchronous belt 212 is connected between the two sets of first pulleys 211. That is, when the negative pressure mechanism 203 is activated, the negative pressure drives the rotating wheel to rotate, thereby realizing the rotation of the first connecting shaft 210. The first pulley 211 and the first synchronous belt 212 realize the rotation of the reciprocating screw 222. The reciprocating screw 222 realizes the reciprocating movement of the cutter 220 to achieve cutting.

[0026] It should be noted that the rotation principle of the connecting disk 204 in this embodiment is as follows: Figure 4 and Figure 8 As shown, the connecting plate 204 and the negative pressure chamber 202 are rotatably connected by a rotating shaft 215. A second pulley 206 is coaxially and fixedly mounted on one of the rotating shafts 215. A first motor 209 is fixedly connected to the outer wall of the negative pressure chamber 202 by a mounting plate 205. The output end of the first motor 209 is coaxially and fixed to the second pulley 206. The two second pulleys 206 are connected by a second synchronous belt 207. That is, the rotation of the first motor 209 can realize the 90-degree rotation of the connecting plate 204.

[0027] like Figure 2 As shown, in this embodiment, the self-adhesive label slitting device 100 includes a base 101, a feeding shaft 102 rotatably mounted on one end of the base 101, a plurality of feeding rollers 103 rotatably mounted on the base 101, a receiving tray 105 rotatably mounted on one end of the base 101, a plurality of receiving shafts rotatably mounted on the receiving tray 105, a cutting mechanism 104 is provided between the feeding shaft 102 and the receiving shaft, the cutting mechanism 104 is provided with a plurality of adjustable-spaced cutters, the cutters can slit the self-adhesive labels, and a discharge pipe 107 is fixedly mounted below the cutting mechanism 104 on the base 101. In use, the cutting mechanism 104 slits the self-adhesive labels, and the edges 106 on both sides of the self-adhesive labels are cut off, generating continuous long strips of cutting waste. The continuous long strips of cutting waste enter the discharge pipe 107 and are discharged. The waste collection device 200 is fixed on the base 101 of the self-adhesive label slitting device 100.

[0028] Example 2 It is understandable that in Embodiment 1, the connecting plate 204 is used to fix woven bags or other bags, but in actual use, the woven bags are usually tied directly to it with ropes, and it is troublesome to repeatedly loosen and tighten the ropes.

[0029] like Figure 5 As shown, to solve the above problems, this embodiment proposes a simpler method for fixing woven bags, such as... Figure 5 As shown, the connecting plate 204 includes a flip cover plate 20401, on which ear plates 20402 are symmetrically and fixedly provided. The ear plates 20402 are rotatably engaged with the negative pressure chamber 202. A circular ring 20403 is rotatably provided on the flip cover plate 20401. The interior of the circular ring 20403 is through-hole. An installation ring 20405 is fixedly provided on the outside of the circular ring 20403. Several grippers 20406 are rotatably provided on the installation ring 20405. The several grippers 20406 can be released or clamped simultaneously.

[0030] like Figure 7 As shown, a first gear 20404 is fixedly provided at the rotatable connection between several grippers 20406 and the mounting ring 20405, such as... Figure 6 As shown, a ring rack 20410 is fixedly mounted on the outside of the mounting ring 20405. A positioning ring 20407 is slidably mounted on the mounting ring 20405. Several sets of connecting rods 20408 are fixedly mounted on the positioning ring 20407. Each of the connecting rods 20408 is vertically and fixedly mounted with a first rack 20409. The first racks 20409 mesh with several first gears 20404 respectively. Figure 5 As shown, a threaded post 20412 is rotatably mounted on the mounting ring 20405. The threaded post 20412 is threadedly engaged with the positioning ring 20407. Several telescopic rods 20413 are also installed between the positioning ring 20407 and the mounting ring 20405. When in use, rotating the threaded post 20412 will cause the positioning ring 20407 to move downward. At this time, several first racks 20409 will move downward synchronously. During the movement, the several first racks 20409 will mesh with the first gear 20404 respectively to realize the rotation of several grippers 20406 to achieve the clamping function and fix the woven bag.

[0031] like Figure 5 As shown, a second gear 20411 is also rotatably mounted on the flip cover 20401. The ring rack 20410 meshes with the second gear 20411 for transmission. The second gear 20411 is driven by a second motor.

[0032] The working principle of connector 204: Figure 5As shown, in use, the woven bag is placed on the ring 20403 and several grippers 20406. The grippers 20406 are then driven to rotate synchronously, clamping the edges of the woven bag and fixing it to the ring 20403. Next, the connecting disc 204 is driven to rotate onto the outlet 216. The negative pressure mechanism 203 activates the airflow, causing it to spiral downwards and carrying the cut waste material from the outlet 216 into the woven bag for collection. After the woven bag is collected, the second motor drives the second gear 20411 to rotate, ultimately causing the grippers 20406 to rotate synchronously. The grippers 20406 then rotate and tighten the opening of the collected woven bag, which, combined with manual sealing, completes the packaging of the waste material.

[0033] It should be emphasized that the core improvement of this embodiment lies in the following: This structure can quickly clamp and fix woven bags through the cooperation of the grippers and the ring, and the assembly and disassembly operations are simple; the connecting plate can rotate to connect with the discharge port, and the positioning is flexible and reliable. During operation, waste material is transported into the bag by negative pressure cyclone, and the collection process is continuous and efficient. After the bag is full, the grippers can rotate synchronously to tighten the bag mouth, assisting in sealing and packaging, greatly simplifying subsequent processing procedures, reducing manual operation steps, improving overall operation efficiency, and effectively preventing waste material from scattering from the bag.

[0034] Example 3 It is understood that in Embodiment 2, the connecting pipe 201 is cylindrical to avoid the accumulation of long strips of waste material inside the connecting pipe 201. In this embodiment, the connecting pipe 201 is also fixedly provided with an inclined plate 218, so that the long strips of waste material can slide along the inclined plate 218 under the action of gravity to avoid the risk of material blockage. The negative pressure chamber 202 is provided with a feed port 219 that matches the shape of the connecting pipe 201.

[0035] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
