Description

Technical Field

[0001] This invention relates to the field of ETFE release film preparation technology, specifically to an apparatus and method for preparing an ETFE release film for packaging. Background Technology

[0002] ETFE is a highly transparent and weather-resistant fluoroplastic that is commonly used in architectural membrane materials, photovoltaic encapsulation, semiconductor manufacturing, and other fields. ETFE release film is an ETFE substrate coated with a release agent. The manufacturing process of ETFE release film involves a series of steps, including raw material processing, coating and feeding, drying and curing, and winding. In the prior art, Chinese invention patent CN115990968A discloses a device for preparing release film for graphite calendering, relating to the field of release film manufacturing equipment technology. A drying chamber is located on the top left side of the base plate, a material handling mechanism is installed above the base plate, and a cutting mechanism is located on one side of the material handling mechanism. When the U-shaped frame moves downwards, it will... The upper recovery rod pushes the pulley to align with the triangular plate. Then, as the fixed frame moves to the right, when the pulley reaches the lowest point of the triangular plate, the heating wire will contact the release film. The high temperature melts the release film, thus completing the cutting of the release film. This allows for automatic cutting of the release film. Since the heating wire is parallel to the release film, it ensures a neat cut, replacing manual cutting and avoiding the impact of human factors such as line of sight deviation and poor hand stability on the cutting quality, which can lead to cutting deviation and tilting of the cutting end. When winding up release film, the winding roller is usually mounted on the rotating roller, and then the release film is wound onto the winding roller by the rotating roller. In order to ensure the stable rotation of the rotating roller, the rotating roller is usually connected to the drive device by bolts. However, after the release film is wound up, the winding roller needs to be removed from the drive roller. Before removing it, the bolts need to be removed. The disassembly process is time-consuming and affects the production efficiency of release film. Summary of the Invention

A first airbag is provided between the other side wall of the push block and the other side wall of the first clearance groove. A first return spring is provided between the first airbag and the second airbag. The first airbag is connected to the second airbag through the first return spring, and the elastic force of the first return spring is greater than that of the second return spring.

[0009] Furthermore, the inner wall of the snap-fit ​​hole is provided with multiple sets of circumferentially distributed limiting grooves, and the outer surface of the insertion rod is provided with a first storage groove corresponding to the position of each limiting groove. A limiting block is slidably arranged inside each first storage groove, and a third reset spring is provided between the lower end of each limiting block and the inner bottom end of the corresponding first storage groove. Each of the aforementioned limiting blocks has oblique cut surfaces on both sides of its upper end.

[0010] Furthermore, the transmission roller has a clearance cavity inside, a double-ended lead screw is rotatably arranged inside the clearance cavity, and a second motor is arranged inside the transmission roller at a position corresponding to the double-ended lead screw, and the end of the double-ended lead screw is connected to the output end of the second motor; The outer surface of the transmission roller has multiple sets of circumferentially distributed grooves, each groove has a connecting plate inside, and each connecting plate has a hinge seat on its inner wall.

[0011] Furthermore, a through groove is provided at the center of each of the grooves, and the through groove communicates with the relief cavity; The outer surface of the double-ended lead screw is screwed with two sets of symmetrically distributed guide collars, and a second support rod is hinged between each set of guide collars and the corresponding hinge seat.

A guide rod is slidably provided between the two sets of guide grooves, and a fourth return spring is provided between the upper end of the guide rod and the inner top of the guide groove. A cutting blade is provided at one end of the guide rod facing the abutment roller.

[0013] Furthermore, the method includes the following steps: Installation of the take-up roller: The take-up roller is installed outside the drive roller. Then, the second motor is started. The second motor drives the relief cavity to rotate, so that the two sets of guide rings come closer to each other. When the two sets of guide rings come closer to each other, with the cooperation of the second support rod, multiple sets of connecting plates are pushed out synchronously, so that the connecting plates contact the inner wall of the take-up roller, ensuring that the take-up rollers of each inner diameter can be fixedly installed outside the drive roller. Placement of the drive roller: Before placing the drive roller with the take-up roller sleeved between the two sets of fixed plates, first squeeze the push block. When the push block moves toward the inside of the first clearance groove, the first airbag is no longer compressed. At this time, the gas inside the second airbag is discharged into the first airbag through the first return spring. The insertion rod retracts into the receiving hole under the left and right of the second return spring. Then, one end of the drive roller is inserted into the connecting sleeve. Then, the force on the push block is removed. Under the action of the second airbag, the insertion rod is inserted into the snap-fit ​​hole, completing the connection between the drive roller and the first motor. When the insertion rod rotates, the elastically set limit block will spring into the limit groove. When the connecting sleeve drives the insertion rod to rotate, the transmission roller will rotate through the cooperation of the limit groove and the limit block. ETFE release film winding: After one end of the produced ETFE release film is wrapped around the upper end of the holding roller, it is wound around the winding roller. Then the first motor is started, and the first motor drives the winding roller to rotate to realize the winding of the ETFE release film. The flexible support roller ensures that the ETFE release film is always taut. When it is necessary to cut the ETFE release film, press down on the guide rod, and the guide rod will drive the cutting blade to cut the ETFE release film at the upper end of the support roller.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a second airbag to push the insert rod into the snap-fit ​​hole to achieve the limiting and fixing of the transmission roller. At the same time, the cooperation of the elastically set limiting block and limiting groove enables the rotational connection between the connecting sleeve and the transmission roller. When it is necessary to disconnect the connection between the connecting sleeve and the transmission roller, the push block is pressed. At this time, the first airbag is no longer compressed, and the gas inside the second airbag is discharged into the first airbag through the first return spring. Under the action of the second return spring, the insert rod retracts into the receiving hole, completing the separation of the connecting sleeve and the transmission roller. No bolts need to be removed, the disassembly efficiency is high, and different sizes of take-up rollers can be installed according to different production needs and production stages. 2. By rotating the clearance cavity, the two sets of guide rings can move closer or further apart. When the two sets of guide rings move closer together, with the cooperation of the second support rod, multiple sets of connecting plates are pushed out synchronously, so that the connecting plates contact the inner wall of the take-up roller, ensuring that the take-up rollers of each inner diameter can be fixedly sleeved on the outside of the drive roller.

The drive assembly drives the winding assembly to rotate, thereby winding the ETFE release film. During the winding process, the tensioning assembly ensures that the ETFE release film is always in a taut state, ensuring that the ETFE release film is tautly wound onto the winding roller 11.

[0019] Example 2: like Figures 2-6 As shown, the equipment and method for preparing the ETFE release film for encapsulation disclosed in Embodiment 2 of the present invention are basically the same in structure as those in Embodiment 1, except that: Two sets of symmetrically distributed fixed plates 2 are provided at one end of the base plate 1, and the transmission roller 10 is disposed between the two sets of fixed plates 2; The drive assembly includes a first motor 7 disposed on one side of one of the set of fixed plates 2, and the output end of the first motor 7 passes through the fixed plate 2 and is connected to a connecting sleeve 3. The connecting sleeve 3 has an annular structure. One end of the transmission roller 10 is inserted into the inside of the connecting sleeve 3, and the other end of the transmission roller 10 is rotatably disposed inside another set of the fixed plates 2. The connecting sleeve 3 has a storage hole 18 at its center.

A first airbag 14 is provided between the other side wall of the push block 12 and the other side wall of the first clearance groove 13. A first return spring 16 is provided between the first airbag 14 and the second airbag 20. The first airbag 14 is connected to the second airbag 20 through the first return spring 16, and the elastic force of the first return spring 16 is greater than the elastic force of the second return spring 21. The inner wall of the snap-fit ​​hole 17 is provided with multiple sets of circumferentially distributed limiting grooves 22. The outer surface of the insertion rod 19 is provided with a first storage groove 23 corresponding to the position of each limiting groove 22. A limiting block 25 is slidably provided inside each first storage groove 23, and a third return spring 24 is provided between the lower end of each limiting block 25 and the bottom end of the corresponding first storage groove 23. Each of the limiting blocks 25 has a beveled surface on both sides of its upper end. Before placing the drive roller 10, which is fitted with the take-up roller 11, between the two sets of fixed plates 2, the push block 12 is first squeezed. When the push block 12 moves toward the inside of the first clearance groove 13, the first airbag 14 is no longer compressed. At this time, the gas inside the second airbag 20 is discharged into the first airbag 14 through the first return spring 16. The insertion rod 19 retracts into the receiving hole 18 under the left and right pressure of the second return spring 21. Then, one end of the drive roller 10 is inserted into the connecting sleeve 3. Then, the force on the push block 12 is removed. Under the action of the second airbag 20, the insertion rod 19 is inserted into the snap-fit ​​hole 17, thus completing the connection between the drive roller 10 and the first motor 7. When the insertion rod 19 rotates, the elastically set limiting block 25 will spring into the limiting groove 22. When the connecting sleeve 3 drives the insertion rod 19 to rotate, the transmission roller 10 will rotate through the cooperation of the limiting groove 22 and the limiting block 25.

A second motor 28 is arranged inside the transmission roller 10 at a position corresponding to the double-headed lead screw 27. The end of the double-headed lead screw 27 is connected to the output end of the second motor 28. The outer surface of the transmission roller 10 has multiple sets of circumferentially distributed grooves 32. Each groove 32 has a connecting plate 33 inside, and each connecting plate 33 has a hinge seat 30 on its inner wall. Each of the grooves 32 has a through groove 34 at its center, and the through groove 34 communicates with the relief cavity 26; The outer surface of the double-ended lead screw 27 is screwed with two sets of symmetrically distributed guide collars 31, and a second support rod 29 is hinged between each set of guide collars 31 and the corresponding hinge seat 30. The take-up roller 11 is fitted onto the outside of the drive roller 10. Then, the second motor 28 is started. The second motor 28 drives the relief cavity 26 to rotate, so that the two sets of guide rings 31 approach each other. When the two sets of guide rings 31 approach each other, with the cooperation of the second support rod 29, multiple sets of connecting plates 33 are pushed out synchronously, so that the connecting plates 33 contact the inner wall of the take-up roller 11, ensuring that the take-up rollers 11 of each inner diameter can be fixedly fitted onto the outside of the drive roller 10.

[0021] Example 4: like Figures 9-10 As shown, the equipment and method for preparing the ETFE release film for encapsulation disclosed in Embodiment 4 of the present invention are basically the same in structure as those in Embodiment 3, except that: Both sets of fixing plates 2 are provided with a first support rod 4 at their upper ends, both sets of first support rod 4 are provided with a first connecting rod 8 on their side walls, and both sets of first connecting rod 8 are provided with a second connecting rod 9 at their lower ends.

When it is necessary to cut the ETFE release film, press down the guide rod 6, and the guide rod 6 drives the cutting blade 37 to cut the ETFE release film at the upper end of the support roller 5.

[0022] The specific solution is as follows: the take-up roller 11 is sleeved on the outside of the transmission roller 10, and then the second motor 28 is started. The second motor 28 drives the relief cavity 26 to rotate, so that the two sets of guide sleeves 31 approach each other. When the two sets of guide sleeves 31 approach each other, with the cooperation of the second support rod 29, multiple sets of connecting plates 33 are pushed out synchronously, so that the connecting plates 33 contact the inner wall of the take-up roller 11, ensuring that the take-up roller 11 is fixedly sleeved on the outside of the transmission roller 10. Then, the push block 12 is squeezed. When the push block 12 moves toward the inside of the first clearance groove 13, the first airbag 14 is no longer compressed. At this time, the gas inside the second airbag 20 is discharged into the first airbag 14 through the first return spring 16. The insertion rod 19 retracts into the receiving hole 18 under the action of the second return spring 21. Then, one end of the transmission roller 10 is inserted into the connecting sleeve 3. Then, the force on the push block 12 is removed. Under the action of the second airbag 20, the insertion rod 19 is inserted into the snap-fit ​​hole 17, completing the connection between the transmission roller 10 and the first motor 7. The elastically set limiting block 25 will spring into the limiting groove 22. When the connecting sleeve 3 drives the insertion rod 19 to rotate, the transmission roller 10 will rotate through the cooperation of the limiting groove 22 and the limiting block 25. After one end of the produced ETFE release film is wrapped around the upper end of the holding roller 5, it is wound onto the take-up roller 11. Then the first motor 7 is started, and the first motor 7 drives the take-up roller 11 to rotate to realize the winding of the ETFE release film. The elastically set support roller 5 ensures that the ETFE release film is always in a taut state. When it is necessary to cut the ETFE release film, press down the guide rod 6, and the guide rod 6 drives the cutting blade 37 to cut the ETFE release film at the upper end of the support roller 5.

When the insertion rod (19) rotates, the elastically set limiting block (25) will spring into the limiting groove (22). When the connecting sleeve (3) drives the insertion rod (19) to rotate, the transmission roller (10) will rotate through the cooperation of the limiting groove (22) and the limiting block (25). ETFE release film winding: After one end of the produced ETFE release film is wrapped around the upper end of the holding roller (5), it is wound around the winding roller (11), and then the first motor (7) is started. The first motor (7) drives the winding roller (11) to rotate to realize the winding of the ETFE release film. The elastically set support roller (5) can keep the ETFE release film in a taut state. When the ETFE release film needs to be cut, press down the guide rod (6), and the guide rod (6) will drive the cutting blade (37) to cut the ETFE release film at the upper end of the support roller (5).
