Description

Technical Field

[0001] The utility model relates to the technical field of waste removal from strip materials, in particular to a device for removing waste from a low-adhesion film and recycling it. Background Art

[0002] According to the process requirements, after multi-layer composite strip materials are die-cut, the products are first discharged, leaving a complete low-adhesion film. There are several sheet-shaped waste materials adhered to the low-adhesion film. It is necessary to strip the waste materials adhered to the low-adhesion film for recycling. The traditional waste stripping device only strips the low-adhesion film once through a stripping knife and a stripping platform. During the stripping process, since the sheet-shaped waste materials are relatively soft, the stripping is often incomplete. Some waste materials continue to move forward with the low-adhesion film and are not completely stripped by the stripping knife, resulting in incomplete waste stripping.

[0003] Therefore, a device for removing waste from a low-adhesion film and recycling it to solve the above problems is needed. Summary of the Utility Model

[0004] The utility model provides a device for removing waste from a low-adhesion film and recycling it. First, the waste materials are stripped for the first time by a stripping knife, and then the waste materials after the first stripping are stripped for the second time by a rotating stripping plate, thereby realizing continuous and thorough stripping of the waste materials on the low-adhesion film.

[0005] The technical solution of the utility model is realized as follows:

[0006] The device for removing waste from a low-adhesion film and recycling it includes a frame. A stripping knife for initially stripping the waste materials on the low-adhesion film is fixedly installed on the frame. Guide rollers for guiding the low-adhesion film are rotatably installed on both sides of the stripping knife. The low-adhesion film bypasses the stripping end of the stripping knife. The low-adhesion film on both sides of the stripping knife forms a commutation stripping angle. A waste stripping shaft is rotatably installed on the frame opposite to the stripping knife. The rotation direction of the waste stripping shaft is opposite to the advancing direction of the low-adhesion film. A plurality of stripping plates for secondarily stripping the waste materials are evenly distributed on the outer peripheral surface of the waste stripping shaft. A waste collection hopper for collecting the stripped waste materials is arranged below the waste stripping shaft.

[0007] As a preferred technical solution, two baffles for preventing the stripped waste materials from adhering to the low-adhesion film again are fixedly installed on the frame. The two baffles are respectively arranged on both sides of the stripping knife. A waste stripping gap is formed between the adjacent ends of the two baffles. The stripping end of the stripping knife is arranged in the waste stripping gap.

[0008] As a preferred technical solution, avoidance inclined surfaces for avoiding the stripping knife and the low-adhesion film are arranged on the side walls of the two baffles close to the stripping knife.

[0009] As a preferred technical solution, a plurality of guiding side plates for guiding the stripped waste to the waste collection hopper are fixedly installed on the frame.

[0010] As a preferred technical solution, the waste collection hopper is fixedly installed on the frame and connected with a blower.

[0011] As a preferred technical solution, an electrostatic eliminator is fixedly installed on the frame. Along the advancing direction of the low-adhesion film, the electrostatic eliminator is arranged downstream of the stripping knife.

[0012] As a preferred technical solution, each of the guiding rollers, baffles, guiding side plates, stripping plates and the waste collection hopper has an anti-sticking surface.

[0013] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] Since the low-adhesion film waste removal and recycling device includes a stripping knife, during the use of the device, under the traction of the traction device, the low-adhesion film continuously advances. The stripping end of the stripping knife abuts against the back of the low-adhesion film. When the low-adhesion film passes through the stripping end of the stripping knife, the low-adhesion film forms a commutation stripping angle, and one end of the waste adhered to the front of the low-adhesion film warps up. The warped waste extends out of the waste stripping gap, and then is pushed away from the low-adhesion film by the rotating stripping plate. Since the rotating direction of the waste stripping shaft is opposite to the advancing direction of the low-adhesion film, the rotating stripping plate pushes the warped waste in the reverse direction, thereby performing secondary waste stripping on the waste, so that the waste is further stripped from the low-adhesion film. As the low-adhesion film continuously advances, continuous stripping of the waste on the low-adhesion film can be realized. The stripped waste falls into the waste collection hopper and waits for recycling. In the present utility model, under the dual action of the stripping knife and the stripping plate, continuous and complete stripping of the waste on the low-adhesion film is realized.

[0015] In the present utility model, the setting of the baffle can prevent the stripped waste from adhering to the stripping knife or the low-adhesion film again. The setting of the avoidance inclined surface on the baffle reduces the distance between the two baffles and the stripping knife, that is, reduces the width of the waste stripping gap. Since the stripping end of the stripping knife is arranged in the waste stripping gap, if the waste stripping gap is smaller, the distance between the baffle and the stripping knife is smaller, and the baffle downstream of the stripping knife can more effectively block the warped end of the waste from adhering back to the low-adhesion film.

[0022] As Figures 1 - 3 collectively shown, the low-adhesion film waste removal and recycling device includes a frame 1, on which a stripping knife 4 for initially stripping the waste material 3 on the low-adhesion film 2 is fixedly installed. Guide rollers 5 for guiding the low-adhesion film 2 are respectively rotatably installed on both sides of the stripping knife 4. The low-adhesion film 2 bypasses the stripping end 6 of the stripping knife 4, and the low-adhesion film 2 on both sides of the stripping knife 4 forms a reversing stripping angle 7. A waste stripping shaft 8 opposite to the stripping knife 4 is rotatably installed on the frame 1. The rotation direction of the waste stripping shaft 8 is opposite to the advancing direction of the low-adhesion film 2. A plurality of stripping plates 9 for secondarily stripping the waste material 3 are evenly distributed on the outer peripheral surface of the waste stripping shaft 8. A waste collection hopper 10 for collecting the stripped waste material 3 is arranged below the waste stripping shaft 8.

[0023] Wherein, two baffles 11 for preventing the stripped waste material 3 from adhering to the low-adhesion film 2 again are fixedly installed on the frame 1. The two baffles 11 are respectively arranged on both sides of the stripping knife 4. A waste stripping gap 12 is formed between the adjacent ends of the two baffles 11, and the stripping end 6 of the stripping knife 4 is arranged in the waste stripping gap 12.

[0024] In addition, avoidance inclined planes 13 for avoiding the stripping knife 4 and the low-adhesion film 2 are respectively arranged on the side walls of the two baffles 11 close to the stripping knife 4.

[0025] In addition, a plurality of guide side plates 14 for guiding the stripped waste materials 3 to the waste material collecting bucket 10 are fixedly mounted on the frame 1 .

[0026] Secondly, the waste collection bucket 10 is fixedly mounted on the frame 1 and is connected to a fan, which is not marked in the figure.

[0027] An electrostatic eliminator 15 is fixedly mounted on the frame 1 , and is disposed downstream of the stripping knife 4 along the advancing direction of the low-viscosity film 2 .

[0028] Each guide roller 5, baffle plate 11, guide side plate 14, stripping plate 9 and waste collection bucket 10 is provided with an anti-adhesive surface. In the utility model, the anti-adhesive surface is made of polytetrafluoroethylene.

[0029] A driving motor 16 is fixedly mounted on the frame 1 , and the driving motor 16 is drivingly connected to the waste stripping shaft 8 .

[0030] Both ends of the two baffles 11 are provided with a long waist hole 17, and a pair of mounting plates 18 are fixedly installed on the frame 1. The two baffles 11 are fixedly installed on the two mounting plates 18 by bolts. In this new use, the bolts are not marked in the figure. The setting of the long waist hole 17 makes the distance between the two baffles 11 adjustable, thereby realizing the adjustment of the waste stripping gap 12, making the present device suitable for stripping waste 3 of different thicknesses, thereby improving the application range of the present device.

[0031] The method of using the utility model is as follows:

[0032] In the first step, under the traction of the traction device, the low-viscosity film 2 continues to move forward. When the low-viscosity film 2 passes through the stripping end 6 of the stripping knife 4, the low-viscosity film 2 forms a reversing stripping angle 7, and one end of the waste material 3 is lifted up from the low-viscosity film 2, thus completing the initial stripping of the waste material 3.

[0033] The second step is, Figure 2 As shown, the low-viscosity film 2 is lifted up and extends out of the waste stripping gap 12. The stripping plate 9 pushes the low-viscosity film 2 extending out of the waste stripping gap 12 in the opposite direction, so that the waste 3 is subjected to a thrust force opposite to the advancing direction of the low-viscosity film 2. As the low-viscosity film 2 advances, the secondary stripping of the waste 3 is completed. This reciprocating process can complete the continuous and complete stripping of the waste 3 on the low-viscosity film 2.

[0034] In the third step, under the action of the fan, negative pressure is formed in the waste collection bucket 10, and the stripped waste 3 falls into the waste collection bucket 10 to be recycled and reused.

[0035] In summary, the utility model firstly performs the first stripping of the waste material by the stripping knife, and then performs the second stripping of the waste material after the first stripping by the rotating stripping plate, thereby realizing the continuous and thorough stripping of the waste material on the low-viscosity membrane.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
