Description

Technical Field

[0001] This utility model relates to the technical field of plastic sheet production, and in particular to a vacuum-assisted rapid peeling device for producing self-adhesive plastic sheets. Background Technology

[0002] Self-adhesive plastic sheets are made by combining high-performance plastic sheets with self-adhesive through a composite process. They require no additional glue or complex tools; simply peel off the protective film and apply directly to the desired surface. This simple process saves time and labor costs. During production, a layer of adhesive is first coated onto a substrate. Before the adhesive layer fully cures, a release liner is applied to the surface to prevent adhesion and contamination. After curing, the release liner is peeled off, and the adhesive layer is inspected for defects such as air bubbles and insufficient adhesive. Finally, a protective film is applied. Currently, the release liner is peeled off manually, which is inefficient, slow, and inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a vacuum-assisted rapid peeling device for the production of self-adhesive plastic sheets that can assist workers in peeling the release film off the surface of plastic sheets, reducing labor intensity, improving work efficiency, and is easy to use and highly practical.

[0004] This utility model discloses a vacuum-assisted rapid peeling device for producing self-adhesive plastic sheets, comprising a base plate; it also includes a rotating mechanism, multiple fixing mechanisms, a peeling mechanism, and a belt conveyor. The multiple fixing mechanisms are mounted on the rotating mechanism, which rotates the fixing mechanisms and provides a fixing function. The peeling mechanism is located in front of the fixing mechanisms and provides a peeling function. The belt conveyor is mounted on the base plate and is located to the right of the rotating mechanism. When peeling the release film from the plastic sheet, the plastic sheet to which the release film needs to be peeled is fixed on the fixing mechanism, and the substrate on the plastic sheet is... The plastic sheet is attracted by the fixing mechanism, causing the release film on the plastic sheet to face forward. Then, the rotating mechanism is opened, which rotates the fixing mechanism, causing the fixing mechanism to rotate the plastic sheet to a position close to the peeling mechanism. Then, the peeling mechanism peels off the release film from the front end of the plastic sheet. After that, the rotating mechanism is opened again, and the plastic sheet with the release film peeled off is rotated to the side close to the belt conveyor. Then, the worker places the peeled plastic sheet on the belt conveyor for transportation. This method can assist workers in peeling the release film off the surface of plastic sheets, reducing labor intensity, improving work efficiency, and is convenient to use and highly practical.

[0005] Preferably, the rotating mechanism includes a support plate, an indexing plate, and a rotating shaft. The support plate is fixedly mounted on the upper end of the base plate, the indexing plate is fixedly mounted on the support plate, and the rotating shaft is fixedly mounted on the rotating end at the front of the indexing plate. Multiple fixing mechanisms are mounted on the rotating shaft. When rotating the fixing mechanisms, the indexing plate is opened, the indexing plate drives the rotating shaft to rotate, and the rotating shaft drives the fixing mechanisms to rotate, so that the fixing mechanisms drive the plastic sheet to rotate sequentially to a position close to the peeling mechanism and the belt conveyor; this facilitates the movement of the plastic sheet.

[0006] Preferably, the fixing mechanism includes a connecting plate, a fixing plate, and multiple electric vacuum suction cups A. The fixing plate is fixedly mounted on the rotating shaft via the connecting plate, and the multiple electric vacuum suction cups A are all fixedly mounted on the fixing plate. When fixing the plastic sheet, the side of the plastic sheet with the substrate is brought into contact with the multiple electric vacuum suction cups A. Then, the multiple electric vacuum suction cups A are opened, allowing them to adsorb and fix the substrate on the plastic sheet. This facilitates the fixing of the plastic sheet.

[0007] Preferably, the peeling mechanism includes a moving mechanism and a mounting plate. The mounting plate is equipped with multiple electric vacuum suction cups B. The mounting plate is mounted on the moving mechanism, which moves the mounting plate back and forth. When peeling the release film from the plastic sheet surface, a rotating mechanism causes the fixing mechanism to rotate the plastic sheet to a position close to the peeling mechanism, causing the release film on the plastic sheet to face the mounting plate. Then, the moving mechanism moves the mounting plate forward, bringing the electric vacuum suction cups B on the mounting plate into contact with the release film on the plastic sheet. The electric vacuum suction cups B then adhere and fix the release film. Next, the moving mechanism moves the mounting plate away from the plastic sheet, allowing the mounting plate to peel off the release film from the plastic sheet surface using the electric vacuum suction cups B, thus completing the separation of the release film from the plastic sheet. Finally, the electric vacuum suction cups B are turned off, allowing the release film on the electric vacuum suction cups B to fall off under gravity.

[0008] Preferably, the moving mechanism includes a vertical plate, a hydraulic cylinder, and a push rod. The vertical plate is fixedly mounted on the base plate, the hydraulic cylinder is fixedly mounted on the vertical plate, and the push rod is slidably mounted on the vertical plate. One end of the push rod is connected to the power output end of the hydraulic cylinder, and the other end of the push rod is fixedly connected to the mounting plate. When controlling the mounting plate to move back and forth, the hydraulic cylinder is opened, and the hydraulic cylinder drives the mounting plate to move back and forth through the push rod. This facilitates the back and forth movement of the mounting plate.

[0009] Preferably, it also includes a support frame and a vision sensor. The support frame is fixedly installed on the base plate, and the vision sensor is fixedly installed on the support frame. The vision sensor is located above the belt conveyor. When the peeled plastic sheet is conveyed on the belt conveyor, the adhesive layer on the plastic sheet is flushed up. Then, the vision sensor is turned on to perform visual inspection on the adhesive layer on the plastic sheet to detect whether there are impurities or bubbles on the surface of the adhesive layer, which improves convenience.

[0010] Preferably, it also includes a collection box, which is placed on the base plate and located below the mounting plate. After the electric vacuum suction cup B on the mounting plate peels off the release film from the plastic sheet, the electric vacuum suction cup B is turned off, so that the release film adsorbed on the electric vacuum suction cup B falls into the collection box for collection, which facilitates the collection of the release film.

[0011] Compared with the prior art, the beneficial effects of this utility model are: it can assist workers in peeling the release film off the surface of plastic sheets, reducing labor intensity, improving work efficiency, and is convenient and highly practical. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0019] like Figures 1 to 5This utility model discloses a vacuum-assisted rapid peeling device for producing self-adhesive plastic sheets, comprising a base plate 1, a rotating mechanism, multiple fixing mechanisms, a peeling mechanism, and a belt conveyor 2. The multiple fixing mechanisms are mounted on the rotating mechanism, which rotates the fixing mechanisms and provides a fixing function. The peeling mechanism is located in front of the fixing mechanisms and provides a peeling function. The belt conveyor 2 is mounted on the base plate 1 and is located to the right of the rotating mechanism. When peeling the release film from the plastic sheet, the plastic sheet to which the release film needs to be peeled is fixed on the fixing mechanism, and the base film on the plastic sheet is... The board is attracted by the fixing mechanism, causing the release film on the plastic sheet to face forward. Then, the rotating mechanism is opened, which rotates the fixing mechanism, causing the fixing mechanism to rotate the plastic sheet to a position close to the peeling mechanism. Then, the peeling mechanism peels off the release film at the front end of the plastic sheet. After that, the rotating mechanism is opened again, and the plastic sheet with the release film peeled off is rotated to the side close to the belt conveyor 2. Then, the worker places the peeled plastic sheet on the belt conveyor 2 for transportation. This can assist workers in peeling the release film off the surface of the plastic sheet, reduce labor intensity, improve work efficiency, and is convenient to use and highly practical.

[0020] like Figure 1 , Figure 3 and Figure 4 The rotating mechanism includes a support plate 3, an indexing plate 4, and a rotating shaft 5. The support plate 3 is fixedly installed on the upper end of the base plate 1, the indexing plate 4 is fixedly installed on the support plate 3, and the rotating shaft 5 is fixedly installed on the rotating end at the front of the indexing plate 4. Multiple fixing mechanisms are installed on the rotating shaft 5. When the fixing mechanisms are rotated, the indexing plate 4 is opened, the indexing plate 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the fixing mechanisms to rotate, so that the fixing mechanisms drive the plastic sheet to rotate sequentially to a position close to the peeling mechanism and the belt conveyor 2; this facilitates the movement of the plastic sheet.

[0021] like Figure 1 and Figure 3 The fixing mechanism includes a connecting plate 6, a fixing plate 7, and multiple electric vacuum suction cups A8. The fixing plate 7 is fixedly mounted on the rotating shaft 5 via the connecting plate 6, and the multiple electric vacuum suction cups A8 are all fixedly mounted on the fixing plate 7. When fixing the plastic sheet, the side of the plastic sheet with the substrate is brought into contact with the multiple electric vacuum suction cups A8, and then the multiple electric vacuum suction cups A8 are opened so that the multiple electric vacuum suction cups A8 can adsorb and fix the substrate on the plastic sheet; this facilitates the fixing of the plastic sheet.

[0022] like Figure 1 and Figure 5The peeling mechanism includes a moving mechanism and a mounting plate 9. The mounting plate 9 is equipped with multiple electric vacuum suction cups B. The mounting plate 9 is mounted on the moving mechanism, which moves the mounting plate 9 back and forth. When peeling the release film from the plastic sheet surface, a rotating mechanism causes the fixing mechanism to rotate the plastic sheet closer to the peeling mechanism, causing the release film on the plastic sheet to face the mounting plate 9. Then, the moving mechanism moves the mounting plate 9 forward, bringing the electric vacuum suction cups B on the mounting plate 9 into contact with the release film on the plastic sheet. The electric vacuum suction cups B then adhere and fix the release film. The moving mechanism then moves the mounting plate 9 away from the plastic sheet, allowing the mounting plate 9 to peel off the release film from the plastic sheet surface using the electric vacuum suction cups B, thus completing the separation of the release film from the plastic sheet. Finally, the electric vacuum suction cups B are turned off, allowing the release film on the electric vacuum suction cups B to fall off under gravity.

The vertical plate 10 is fixedly mounted on the base plate 1, the hydraulic cylinder 11 is fixedly mounted on the vertical plate 10, and the push rod 12 is slidably mounted on the vertical plate 10. One end of the push rod 12 is connected to the power output end of the hydraulic cylinder 11, and the other end of the push rod 12 is fixedly connected to the mounting plate 9. When controlling the mounting plate 9 to move back and forth, the hydraulic cylinder 11 is opened, and the hydraulic cylinder 11 drives the mounting plate 9 to move back and forth through the push rod 12, which facilitates the back and forth movement of the mounting plate 9.

[0024] It also includes a collection box 15, which is placed on the base plate 1 and located below the mounting plate 9. When the electric vacuum suction cup B on the mounting plate 9 peels off the release film from the plastic sheet, the electric vacuum suction cup B is turned off, so that the release film adsorbed on the electric vacuum suction cup B falls into the collection box 15 for collection, which facilitates the collection of the release film. Example 2

[0025] Based on Example 1, such as Figure 1 and Figure 2 It also includes a support frame 13 and a vision sensor 14. The support frame 13 is fixedly installed on the base plate 1, and the vision sensor 14 is fixedly installed on the support frame 13. The vision sensor 14 is located above the belt conveyor 2. When the peeled plastic sheet is conveyed on the belt conveyor 2, the adhesive layer on the plastic sheet is flushed up. Then the vision sensor 14 is turned on to perform visual inspection on the adhesive layer on the plastic sheet to detect whether there are impurities or bubbles on the surface of the adhesive layer, which improves convenience.

[0026] It should be noted that:

[0027] 1. The indexing plate 4 in this case has an angle self-locking function, and the indexing plate 4, hydraulic cylinder 11, belt conveyor 2 and electric vacuum suction cup A8 are all connected to an external controller, which coordinates and controls the operation of each electrical device.

[0028] 2. This case requires two workers. One worker stands near the fixed mechanism on the left and attaches the plastic sheet on the fixed mechanism to which the release film needs to be peeled off. The other worker stands near the belt conveyor 2 and removes the plastic sheet from the fixed mechanism after the release film has been peeled off and places it on the belt conveyor 2.
