Description

Technical Field

[0001] This utility model relates to the field of dimming film technology, specifically to a clamping device for dimming film production. Background Technology

[0002] Lamination of dimming film refers to the process of bonding dimming film with other substrates using adhesives to form a composite product with dimming function. It is also a key step in realizing the combination of "functional layer + carrier" in the application of dimming film. Its core purpose is to firmly bond the dimming film to a rigid or flexible substrate, while ensuring that the optical clarity, structural stability and dimming performance of the composite product are not affected. Existing lamination equipment for dimming film production usually consists of an unwinding mechanism, a worktable and an adhesive supply system.

[0003] However, in the existing dimming film production equipment, the unwinding mechanism still cuts the dimming film manually. This method is prone to errors in the cut dimming film, and the unwinding mechanism is prone to insufficient tension after unwinding, resulting in uneven stretching in some areas and wrinkles after lamination.

[0004] Therefore, there is a need to provide a lamination device for producing dimming films. Utility Model Content

[0005] The purpose of this utility model is to provide a laminating device for producing dimming film, so as to solve the problem mentioned in the background art that the unwinding mechanism of the existing laminating device for producing dimming film mostly cuts the dimming film manually. This makes the cut dimming film prone to errors, and the unwinding mechanism is prone to insufficient tension after unwinding, resulting in uneven local stretching and wrinkles after lamination.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for producing dimming film, comprising a processing table, a support fixedly installed at the bottom of the processing table, a base plate fixedly connected to one side of the support, a material conveying assembly and a transmission assembly fixedly installed at the top of the base plate, a tension adjustment assembly disposed below the material conveying assembly, a fixed-length cutting assembly installed on the transmission assembly, a control panel fixedly installed on the support, and an adjustment switch and a material conveying switch sequentially installed on the surface of the control panel.

[0007] Preferably, the feeding assembly includes two mounting plates, which are respectively fixedly installed on both sides of one end of the base plate, and a dimming film roll is rotatably installed between the two mounting plates.

[0008] Preferably, the tension adjustment assembly includes two fixed seats, both of which are fixedly mounted on the base plate. A bidirectional lead screw is rotatably mounted between the two fixed seats. A first output motor is fixedly mounted at one end of the bidirectional lead screw. The first output motor is fixedly mounted outside one of the fixed seats. Two transmission blocks are symmetrically connected to the outer side of the bidirectional lead screw. A first rotating seat is fixedly mounted on the top of the transmission blocks.

[0009] Preferably, each of the two first rotating seats is rotatably connected to a connecting rod, and a second rotating seat is rotatably mounted at one end of the connecting rod. A lifting plate is fixedly mounted on the top between the two second rotating seats. Lifting rods are fixedly mounted on the four corners of the bottom of the lifting plate. The four lifting rods are slidably mounted on both ends inside the two fixed seats. Multiple springs are fixedly mounted inside the lifting plate. A tension adjusting plate is fixedly connected to the top between the multiple springs. The tension adjusting plate is slidably connected inside the lifting plate to correct the tension state of the material in real time, ensuring that the dimming film and the substrate are completely flat and aligned when stacked, avoiding adhesive bubbles or poor local adhesion caused by wrinkles.

[0010] Preferably, the transmission assembly includes a fixed frame, which is fixedly installed on the top of the base plate. A rotating shaft and two material transfer rollers are rotatably installed in the middle of the base plate. One end of one of the material transfer rollers is fixedly installed with a driven gear. One end of the rotating shaft is fixedly installed with a transmission gear. The other end of the rotating shaft is fixedly connected to a second output motor. Two cams are fixedly installed on the outer side of the rotating shaft. The transmission gear meshes with the driven gear.

[0011] Preferably, the cutting assembly includes two sliding seats, which are respectively fixedly installed at both ends of the top of the fixed frame. A sliding rod is slidably installed inside the sliding seat, and a cutter is fixedly installed at the bottom between the two sliding rods. A tension spring is sleeved in the middle of each of the two sliding rods. One end of each tension spring is fixedly connected to the outside of the two sliding seats, and the bottom of each tension spring is fixedly connected to the cutter. The product after fixed-length cutting can directly enter the next stage without additional trimming, saving labor and time costs.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The tension adjustment component can be used to adjust the tension of the dimming film roll during feeding, preventing uneven stretching of the dimming film due to tension fluctuations, which can lead to wrinkles after lamination.

[0014] By using the cutting components, the dimming film can be cut to a fixed length each time. Fixed-length cutting can be combined with automated production lines to achieve continuous operation, reduce the frequency of manual adjustments, greatly increase the processing volume per unit time, and ensure that the size of each dimming film is uniform.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides a clamping device for producing dimming film, including a processing table 1, a support 2 fixedly installed at the bottom of the processing table 1, a base plate 4 fixedly connected to one side of the support 2, a material conveying component and a transmission component fixedly installed at the top of the base plate 4, a tension adjustment component provided below the material conveying component, a fixed length cutting component installed on the transmission component, a control panel 3 fixedly installed on the support 2, and an adjustment switch and a material conveying switch sequentially installed on the surface of the control panel 3.

[0023] Furthermore, the material conveying assembly includes two mounting plates 5, which are respectively fixedly installed on both sides of one end of the base plate 4. A dimming film roll 6 is rotatably installed between the two mounting plates 5. The tension adjustment assembly includes two fixed seats 7, both of which are fixedly installed on the base plate 4. A bidirectional lead screw 8 is rotatably installed between the two fixed seats 7. A first output motor 9 is fixedly installed at one end of the bidirectional lead screw 8. The first output motor 9 is fixedly installed outside one of the fixed seats 7. Two transmission blocks 10 are symmetrically connected to the outer side of the bidirectional lead screw 8. A first rotating seat 11 is fixedly installed on the top of the transmission block 10. A connecting rod 12 is rotatably connected inside each of the two first rotating seats 11. A second rotating seat 13 is rotatably installed at one end of the connecting rod 12. A lifting plate 14 is fixedly installed at the top between the two second rotating seats 13. The bottom of the lifting plate 14... Lifting rods 15 are fixedly installed at the four corners of the part. The four lifting rods 15 are slidably installed at both ends inside the two fixed seats 7. Multiple springs 17 are fixedly installed inside the lifting plate 14. Tension adjustment plates 16 are fixedly connected to the top between the multiple springs 17. Tension adjustment plates 16 are slidably connected inside the lifting plate 14. The first output motor 9 is started to drive the bidirectional lead screw 8 to rotate, so that the bidirectional lead screw 8 simultaneously drives the two transmission blocks 10 to move in opposite directions. When the two transmission blocks 10 are close, the first rotating seat 11 at the top drives the connecting rod 12 to flip. One end of the connecting rod 12 drives the second rotating seat 13 to squeeze the lifting plate 14, so that it rises along the fixed seat 7 through the four lifting rods 15. Conversely, when the two transmission blocks 10 are far apart, the lifting plate 14 is pulled down along the fixed seat 7 through the four lifting rods 15.

[0024] Furthermore, the transmission assembly includes a fixed frame 24, which is fixedly mounted on the top of the base plate 4. A rotating shaft 20 and two material transfer rollers 18 are rotatably mounted in the middle of the base plate 4. One end of one material transfer roller 18 is fixedly mounted with a driven gear 19. One end of the rotating shaft 20 is fixedly mounted with a transmission gear 23, and the other end of the rotating shaft 20 is fixedly connected to a second output motor 22. Two cams 21 are fixedly mounted on the outer side of the rotating shaft 20. The transmission gear 23 meshes with the driven gear 19. The cutting assembly includes two sliding seats 26, which are respectively fixedly mounted at both ends of the top of the fixed frame 24. A sliding rod 27 is slidably mounted inside the sliding seat 26. A cutter 25 is fixedly mounted at the bottom between the two sliding rods 27. A tension spring 28 is sleeved in the middle of each of the two sliding rods 27. One end of each tension spring 28 is fixedly connected to the outside of the two sliding seats 26. The bottom of each tension spring 28 is fixedly connected to the cutter 25. When the second output motor 22 is started, it drives the rotating shaft 20 at the output end to rotate. When the rotating shaft 20 rotates, it drives the transmission gear 23 to rotate synchronously and mesh with the driven gear 19. When the driven gear 19 rotates, it drives the fixedly connected material conveying roller 18 to rotate for material conveying. At the same time, when the rotating shaft 20 rotates, it drives the two cams 21 to rotate. When the cam 21 rotates one revolution, it squeezes the cutter 25 through one end, causing the cutter 25 to descend and cut material through the sliding seat 26 connected by the two fixedly connected sliding rods 27. It also pulls the tension spring 28 to bear force. When the cam 21 continues to rotate to a certain extent, it stops squeezing the cutter 25. At this time, the tension spring 28 releases the tension and drives the cutter 25 to reset until the cam 21 rotates to the next revolution and squeezes the cutter 25 again to cut material. This achieves the intermittent descent and cutting of material by the cutter 25.

[0025] In this embodiment, the dimming film roll 6 is rotated and installed between the mounting plates 5. Then, one end of the dimming film is passed between the two feed rollers 18. The first output motor 9 is started by the adjustment switch on the control panel 3 to drive the lifting plate 14 to rise, so that the tension adjustment plate 16 slidably installed inside it contacts the dimming film roll 6 to adjust the tension. Then, the first glass is placed on the processing table 1, and then a layer of film is placed. Then, the second output motor 22 is started by the feed switch on the control panel 3 to feed the dimming film and cut it to a fixed length. The cut dimming film is placed on top of the film, and then the protective film on the dimming film is peeled off. Then, another layer of film is placed on the dimming film, and then the second glass is placed. Then, these stacked materials are pressed together, and then subsequent heating and other steps are performed to complete the glass dimming film lamination. During the continuous feeding and processing, the tension is controlled in real time by the first output motor 9 according to the tension situation to prevent the dimming film from being easily stretched unevenly due to tension fluctuations, which could lead to wrinkles after lamination.
