Description

[0001] The invention relates to the technical field of double-sided adhesive tape waste treatment, in particular to a device for separating adhesive residue and recovering waste from double-sided adhesive tape production. Background Art

[0002] During the double-sided tape production process, adhesive residue primarily originates from equipment cleaning, adhesive changes, and coating blade cleaning during the coating process. This residue is a mixture of uncured or semi-cured adhesive, solvents, release paper / film debris, dust, and other impurities. Efficiently separating and recycling adhesive residue is crucial to reducing costs and minimizing environmental impact.

[0003] Currently, solid or sticky rubber residue is usually separated by material screening, which usually uses a single or multi-layer fixed screen to achieve particle classification through vibration. However, due to its strong viscosity, the rubber residue easily adheres to the surface of the screen, causing clogging of the screen holes, requiring frequent shutdowns for cleaning, and reducing production efficiency. At the same time, it is difficult for the adhered rubber particles to completely separate from the screen, resulting in waste of raw materials. Although there are tiltable screen designs in the prior art, their vibration mode is single and the clearing effect is limited. The waste discharge mechanism mostly relies on external conveyor belts and is not integrated with the screening process, resulting in the inability to recycle the rubber particles remaining in the large particle impurities.

The rotating roller 421 is rotatably provided on the discharge cylinder 41 through the support rings. A plurality of pushing tools 422 are tilted and slidably provided on the eight surfaces of the rotating roller 421, and the central plane of the rotating roller 421 is used as a symmetry plane. The plurality of pushing tools 422 located at both ends of the symmetry plane are tilted in opposite directions and are arranged in a spiral.

[0039] In addition, the power source for the rotating roller 421 to rotate along the discharge cylinder 41 is an external driving mechanism, such as a gear ring mechanism and a worm gear;

[0040] The plurality of pusher tools 422 are divided into three groups along the length direction of the rotating roller 421. A sliding rod 423 is fixedly provided in the rotating roller 421. A sleeve rod 1 424 is symmetrically slidably provided on the sliding rod 423. A sleeve rod 2 425 is slidably provided on the sleeve rod 1 424. The two sleeve rods 1 424 are hinged to a group of pusher tools 422 located in the middle position of the rotating roller 421 through a hinge rod 1. The two sleeve rods 2 425 are respectively hinged to the two groups of pusher tools 422 located at both ends of the rotating roller 421 through a hinge rod 2.

[0041] The first screening seat 21 and the second screening seat 23 are configured in two groups and are symmetrically rotatably arranged on the discharge cylinder 41. The rotating ring 25 is rotatably arranged on the discharge cylinder 41. A guide groove 211 is provided on the first screening seat 21. A plurality of guide blocks 15 are fixedly provided on the housing 1. The guide blocks 15 are slidably arranged along the guide groove 211. The output end of the second screening seat 23 is arc-shaped and tangent to the side wall of the housing 1. Rotating blocks 231 are symmetrically fixed on the second screening seat 23. A straight groove 16 is provided on the housing 1 for the rotating blocks 231 to slide and rotate.

[0042] A feeding plate 17 and a discharging plate 18 are respectively fixedly and tilted on the top and bottom of the housing 1 .

[0043] During implementation, the glue residue to be separated is transported into the shell 1 through the conveying plate 17 on the top of the shell 1, so that the glue residue falls on the uppermost screening component 2, and then the hydraulic pressure is used to drive the hydraulic support rod 322 to slide along the hydraulic chamber 14, so that the driving block 32 drives the driving plate 31 to slide, thereby driving the discharge barrel 41 and the pushing mechanism 42 to slide up and down. At this time, the two first screening seats 21 arranged on the discharge barrel 41 will rotate along the discharge barrel 41 under the pulling force of the discharge barrel 41 and the limiting action of the guide block 15, so that the first screen 22 is in an inclined state, and as the driving plate 31 slides up and down, the inclination direction of the first screen 22 will switch back and forth, so that the glue residue will be tilted along the first screen The surface of 22 rolls back and forth, and the large particles mixed in the glue residue during the rolling process then pass through the first screen 22 and fall onto the next layer of screening assembly 2 for further screening. At the same time, the second screening seat 23 will synchronously rotate along the first screening seat 21. At the same time, the output end of the second screening seat 23 will always be tangent to the side wall of the shell 1 under the restriction of the rotating block 231 and the straight groove 16, that is, the glue residue can only pass through the first screen 22 and the second screen 24 to enter the next layer of screening assembly 2 for screening, thereby realizing multi-layer screening of the glue residue. In this process, when the driving block 32 drives the ear plate 311 to slide up and down to the end of the first vertical slot 12, the ear plate 311 will stop sliding under the action of the top block 33. When the lever 32 is in the unlocked position, the push rod 33 is in the unlocked position, and the push rod 33 is in the unlocked position, so that the push rod 33 is unlocked and the push rod 33 is unlocked. , and then when the top block 33 is not restricted, it deflects quickly again, and the corresponding second screen 24 is synchronized with the movement of the first screen 22, so that the rubber particles adhering to the first screen 22 and the second screen 24 will separate from the first screen 22 and the second screen 24 under the action of inertia. At the same time, the ear plate 311 will also vibrate when it hits the shell 1, further allowing the rubber particles to separate from the first screen 22 and the second screen 24, thereby avoiding the rubber particles from clogging the screen. After a period of back and forth screening, a large amount of large particles will remain on the surface of the first screen 22. At this time, the hydraulic pressure is used to drive the two curved plates 44 to slide, so that the feed port is opened, and the large particles enter the discharge barrel 41 from the feed port, and then the feed port is reclosed.At the same time, the two sleeve rods 424 are driven to slide, so that the pusher tool 422 in the middle of the rotating roller 421 is retracted, and then the rotating roller 421 is driven to rotate clockwise, so that the two groups of pusher tools 422 on both sides of the rotating roller 421 can push the large particles to the center of the discharge cylinder 41. In this process, the large particles will slide along the surface of the third screen 45, so that the rubber particles mixed in the large particles that have not been completely screened out will be further screened out through the third screen 45 and fall onto the next layer of screening assembly 2. When the large particles are pushed to the middle position of the discharge cylinder 41, the two sleeve rods 424 are driven to slide, so that the group of pusher tools 422 in the middle of the rotating roller 421 is pushed out, and the rotating roller 421 is driven to rotate clockwise. The movable roller 421 rotates counterclockwise, so that the large particles in the discharge barrel 41 are pushed to the two ends of the discharge barrel 41 by the action of the pushing tool 422. During this process, the large particles in the middle position of the discharge barrel 41 that have not been screened twice will be further screened through the third screen 45. Then the discharge port 411 is opened, so that the large particles are discharged from the discharge port 411 and collected. Similarly, the rubber particles that fall onto the second layer of screening component 2 will be further screened according to size. The larger rubber particles are discharged from the discharge barrel 41, and the remaining rubber particles are further entered into the next screening component 2 for screening. In this way, the rubber particles are screened and collected layer by layer. During the screening process, the problem of rubber particles adhering to the screen and clogging the screen can be effectively avoided, and the screening is more refined.

[0044] In this embodiment, Figure 7 and Figure 8 A driving rod 426 is fixedly provided on the side of the rotating roller 421, and two annular cavities are formed inside the driving rod 426. A push ring 1 427 and a push ring 2 428 are respectively provided in the two annular cavities for sealing and sliding. The push ring 1 427 is fixedly connected to the sleeve rod 1 424 through multiple support rods 1, and the push ring 2 428 is fixedly connected to the sleeve rod 2 425 through multiple support rods 2. A sealing cover 429 is rotatably provided at the end of the driving rod 426, and two hydraulic pipes for respectively delivering hydraulic pressure to the two annular cavities are fixedly provided on the sealing cover 429.

[0045] It should be noted that in order to prevent the rubber particles from adhering to the pushing tool 422, the pushing tool 422 can be regularly retracted into the rotating roller 421 by driving the sleeve rod 1 424 and the sleeve rod 2 425 to slide, and at the same time, a cooling medium is introduced into the rotating roller 421, so that the temperature of the pushing tool 422 and the entire rotating roller 421 and the inside of the discharge barrel 41 is reduced, thereby making the rubber particles brittle and reducing their viscosity, thereby preventing the rubber particles from adhering to the pushing mechanism 42.

[0046] In summary, when the present invention is implemented, the combined design of the screening component 2, the driving mechanism 3 and the discharge component 4 enables the screening component 2 to have efficient anti-blocking performance under the cooperation of the driving mechanism 3, that is, under the cooperation of the driving block 32, the moving block 34, the top block 33 and the ear plate 311, the ear plate 311 and the driving plate 31 can realize emergency stop and release action, thereby enabling the first screening seat 21 and the second screening seat 23 to be able to deflect and shake quickly, and then utilize the combination of inertial force and vibration force to peel off the rubber particles, ensuring that the screen will not be blocked during the screening process. At the same time, after the screening component 2 completes the first screening, the discharge component 4 can be used to perform a deeper secondary screening work, further making the screening more complete. At the same time, a retractable pushing tool 422 is provided, so that the three groups of pushing tools 422 can push the rubber residue alternately, thereby enabling the residual rubber particles to be effectively screened out, effectively improving the waste recovery rate.
