Description

Technical Field

[0001] The utility model relates to the technical field of adhesive film winding, in particular to a driving device for an adhesive film winding roller. Background Art

[0002] The superiority of photovoltaic encapsulation adhesive film in terms of adhesion, durability, optical properties, etc. makes it more and more widely used in current components and various optical products. After the adhesive film is produced by an extruder, it reaches the winding position after operations such as cooling, tensioning, thickness measurement, slitting, etc. At the winding position, the winding roller is connected to the winding driving device to complete the winding of the adhesive film. The existing winding roller is as Figure 1 shown, with a gear arranged at one end, and the rotation of the winding roller is realized by gear cooperation. The structures at both ends of the winding roller are relatively complex. Now a new winding roller has been developed, as Figure 2 shown, with a relatively simple overall structure, but the existing gear driving method cannot drive this winding roller to wind. Summary of the Invention

[0003] In order to solve the problem that the existing driving device cannot drive the new winding roller to rotate and wind, the utility model provides a driving device for an adhesive film winding roller, which can conveniently realize the driving of the new winding roller to rotate and wind.

[0004] Its technical solution is as follows: A driving device for an adhesive film winding roller includes a left bracket and a right bracket. Guide bars are arranged at the tops of the left bracket and the right bracket. It is characterized in that transverse seats are installed on both the left bracket and the right bracket. A transverse guiding cylinder is installed on the transverse seat. A transverse moving pipe connected to a transverse cylinder is arranged in the transverse guiding cylinder. A rotatable rotating shaft is installed in the transverse moving pipe. One end of one of the rotating shafts is connected to a winding driving device, and a bevel gear is installed at the other end. A conical top block is installed at one end of the other rotating shaft. An upper pressing device is installed at the top of the transverse seat.

[0005] It is further characterized in that the upper pressing device includes an L-shaped plate fixed to the top of the transverse seat. A longitudinal cylinder is installed on the L-shaped plate. A pressing block is installed on the piston rod of the longitudinal cylinder. An arched plate with arc-shaped notches at the bottom and arranged at intervals is installed at the bottom of the pressing block. Rollers are respectively installed on both sides of the arched plate through pin shafts;

[0006] Guide grooves are opened on both sides of the transverse guiding cylinder. Guide blocks penetrating the guide grooves are arranged on both sides of the transverse moving pipe. The guide blocks are connected to the piston rods of the transverse cylinders on both sides;

[0007] Horizontal guide rails are installed on the outer sides of both the left bracket and the right bracket. The transverse seat is connected to the horizontal guide rails through sliders. The transverse seat is connected to a transverse moving driving device;

[0008] The coiling drive device includes a housing. A drive motor is fixed below the housing. A drive wheel is installed on the motor shaft of the drive motor. A driven wheel cooperating with the drive wheel is also installed in the housing through a transmission shaft. The drive wheel and the driven wheel are connected by a synchronous belt. A large gear is also installed on the transmission shaft. A small gear meshing with the large gear is installed at one end of one of the rotating shafts. The thickness of the small gear is less than that of the large gear.

[0009] After adopting the present utility model, a bevel gear and a bevel top block are respectively arranged on the left bracket and the right bracket. After synchronously moving inwards horizontally, the coiling roller is clamped. Then, under the cooperation of the bevel gear and the internal gear ring at one end of the new coiling roller, the coiling roller can be driven to rotate. The upper pressing device can press the coiling roller to prevent it from shaking, facilitating the rotation and coiling operation of the new coiling roller. Description of the Drawings

[0016] As shown in Figures 3 to 6 A film coiling roller drive device includes a left bracket 1 and a right bracket 2. Guide bars 3 are arranged at the tops of the left bracket 1 and the right bracket 2. The guide bars are used to support the coiling roller and enable it to roll along the guide bars. Transverse movement seats 4 are installed on both the left bracket 1 and the right bracket 2. A transverse guide cylinder 5 is installed on the transverse movement seat 4. A transverse movement tube 7 connecting a transverse cylinder 6 is arranged in the transverse guide cylinder 5. Specifically, guide grooves 8 are formed on both sides of the transverse guide cylinder 5. Guide blocks 9 penetrating the guide grooves 8 are arranged on both sides of the transverse movement tube 7. The guide blocks 9 are connected to the piston rods of the transverse cylinders 6 on both sides. In order to limit the movement of the transverse movement tube 7, limit pins 10 are also arranged on the transverse movement seat 4.

[0017] A rotatable rotating shaft 11 is installed inside the transverse movement pipe 7. One end of one of the rotating shafts 11 is connected to a winding drive device, and a bevel gear 12 is installed at the other end. A conical top block 13 is installed at one end of the other rotating shaft 11. An upper pressing device is installed at the top of the transverse movement seat 7. The upper pressing device includes an L-shaped plate 14 fixed to the top of the transverse movement seat 4. A longitudinal cylinder 15 is installed on the L-shaped plate 14. A pressing block 16 is installed on the piston rod of the longitudinal cylinder 15. An arched plate 17 with arc-shaped notches at the bottom and arranged at intervals is installed at the bottom of the pressing block 16. Roller 18 is installed on both sides of the arched plate 17 through a pin shaft respectively, which can press the winding roller to prevent it from shifting and does not affect the rotation of the winding roller.

[0018] Horizontal guide rails 19 are installed on the outer sides of the left support 1 and the right support 2. The transverse movement seat 4 is connected to the horizontal guide rail 19 through a slider 20. The transverse movement seat 4 is connected to a transverse movement drive device. The transverse movement drive device generally adopts a chain type. During the winding process, as the adhesive film on the winding roller becomes more and more, the thickness increases. Therefore, it is necessary to gradually move outwards. So, a transverse movement drive device is set to drive the transverse movement seat 4 to gradually move outwards during winding. This structure is an existing technology.

[0019] The winding drive device includes a housing 21. A drive motor 22 is fixed below the housing 21. A drive wheel 23 is installed on the motor shaft of the drive motor 22. A driven wheel 25 that cooperates with the drive wheel 23 is also installed in the housing 21 through a transmission shaft 24. The drive wheel 23 and the driven wheel 25 are connected by a synchronous belt 26. A large gear 27 is also installed on the transmission shaft 24. A small gear 28 that meshes with the large gear 27 is installed at one end of one of the rotating shafts 11. The thickness of the small gear 28 is less than the thickness of the large gear 27 to ensure that the small gear 28 always meshes with the large gear 27 when following the rotating shaft 11 to move transversely.

[0020] The working process is as follows: When loading the winding roller, the transverse cylinder 6 drives the transverse movement pipe 7 to retract outwards, and at the same time drives the rotating shaft 11 together. The bevel gear 12 and the conical top block 13 move outwards at the same time. The winding roller moves along the guiding strip 3 to the position. Then the longitudinal cylinder 15 drives the arched plate 17 to press down, so that the rollers 18 press the winding roller. Then the transverse cylinder 6 drives the transverse movement pipe 7 to move inwards, so that the bevel gear 12 and the conical top block 13 are inserted from both sides of the winding roller. On one side of the left support 1, a gear and a gear ring are matched to clamp the winding roller from both sides. Then the drive motor 22 works, and through transmission, the winding roller can rotate smoothly.
