Description

Technical Field

[0001] The present invention relates to the field of photovoltaic module manufacturing, and in particular to photovoltaic module manufacturing equipment and a manufacturing process thereof. Background Art

[0002] Photovoltaic backsheet film is a key material used in solar cell modules. It covers the backsheet surface and acts as a protective film or anti-reflection coating. Its main functions are: Protecting the backsheet and panels: Photovoltaic backsheet film protects the backsheet and panels from oxidation and chemical corrosion, thereby improving the durability and reliability of solar cell modules. Improving light reflectivity: By reflecting sunlight, photovoltaic backsheet film increases the solar cell's light absorption rate, thereby improving power generation efficiency. Waterproofing and dustproofing: Photovoltaic backsheet films, such as fluorinated films, offer excellent water-proof, dust-proof, and anti-fouling properties, protecting the backsheet from moisture and dust.

[0003] In existing technology, photovoltaic backsheet film needs to be cut into sheets of specified lengths and then collected and overlapped. However, the cutting and collection of photovoltaic backsheet film often requires manual intervention, and due to the flexibility of photovoltaic backsheet film, collection and overlap are very troublesome. Therefore, we provide a photovoltaic module manufacturing equipment and manufacturing process. Summary of the Invention

[0004] The present invention aims to solve the technical problem of how to automatically cut and collect backsheet films according to specifications, and provides a photovoltaic module manufacturing device and a manufacturing process thereof.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A photovoltaic module manufacturing device includes a moving device, a conveying device, a collecting device, a cutting device, a winding roller, a mounting frame, and a controller. The axis of the winding roller is horizontal, and the winding roller is arranged on the mounting frame and is rotatably connected to the mounting frame. The collecting device is arranged to the side of the winding roller and is connected to the mounting frame. The moving device is arranged above the collecting device and is connected to the mounting frame. The moving direction of the moving device is arranged horizontally and perpendicular to the axis of the winding roller. The moving device is electrically connected to the controller. The conveying device is arranged directly above the collecting device and is connected to the moving device. The cutting device is arranged to the side of the conveying device along the conveying direction and is connected to the conveying device. The controller is electrically connected to the moving device.

[0007] When the backsheet film needs to be cut, the staff controls the moving device to move backward through the controller, and the moving device drives the conveying device to move backward. At the same time, the conveying device continuously conveys the backsheet film, and then cuts the backsheet film through the cutting device, so that the backsheet film falls onto the collecting device, thereby automatically cutting and collecting the backsheet film according to specifications.

[0008] Furthermore, the collection device includes a collection platform and a plurality of telescopic springs. The plurality of telescopic springs are vertically arranged with their lower ends fixedly connected to the mounting frame. The collection platform is horizontally arranged above the plurality of telescopic springs and fixedly connected to their upper ends.

[0009] As the weight of the backsheet membrane on the collecting platform increases, several telescopic springs will be gradually compressed, so that the top surface of the backsheet membrane on the collecting platform and the guide plate always maintain an appropriate distance, thereby improving the collection effect of the backsheet membrane.

[0010] Furthermore, the moving device includes a reciprocating screw, an anti-rotation plate, and a drive motor. The anti-rotation plate is positioned transversely above the collection platform and fixedly connected to the mounting bracket. The reciprocating screw is positioned transversely and along the conveying direction, positioned below the anti-rotation plate. Both ends of the reciprocating screw are rotationally connected to the anti-rotation plate, with its rotation axis coinciding with its own axis. The reciprocating screw's slider is in close contact with the bottom surface of the anti-rotation plate. The drive motor's rotating shaft is coaxially fixedly connected to one end of the reciprocating screw, which is fixedly connected to the anti-rotation plate and electrically connected to the controller.

[0011] The staff controls the drive motor to start through the controller, and the drive motor drives the reciprocating screw to rotate, and the reciprocating screw first drives the conveying device and the cutting device to move back and forth.

[0012] Furthermore, the conveying device includes a first movable roller, a second movable roller, a linkage gear, an anti-rotation gear, a linkage rack, two driven gears, and two support plates. The two support plates are arranged vertically and parallel to the axis of the reciprocating screw. The two support plates are arranged opposite each other and located below the anti-rotation plate. The upper ends of the two support plates are fixedly connected to the slider of the reciprocating screw. The axis of the first movable roller is perpendicular to the two support plates and is located between the two support plates. The two end shafts of the first movable roller are rotatably connected to the two support plates. The axis of the second movable roller is parallel to the axis of the first movable roller and is located between the two support plates and below the first movable roller. The two end shafts of the second movable roller are rotatably connected to the two support plates. The distance between the first movable roller and the second movable roller is adapted to the thickness of the backsheet film. Two driven gears are arranged outside the two support plates and are coaxially fixedly connected to the rotating shafts of the first movable roller and the second movable roller, respectively. The two driven gears mesh with each other. The linkage gear is a ratchet structure, arranged outside the two support plates and connected to the rotating shaft of the first movable roller. The linkage rack is parallel to the axis of the reciprocating screw and located below the linkage gear. One end of the linkage rack is fixedly connected to the anti-rotation plate, and the top of the linkage rack meshes with the linkage gear. The anti-rotation gear is a ratchet structure, located outside the two support plates, below the linkage rack, and connected to the rotating shaft of the second movable roller.

[0013] Furthermore, the linkage gear includes a first ratchet, a first pawl, and a first spring. The axis of the first ratchet coincides with the axis of the rotating shaft of the first movable roller and is rotatably connected to the support plate. Its rotation axis coincides with its own axis, and the first ratchet engages with the top of the linkage rack. The first pawl is disposed inside the first ratchet, with one end rotatably connected to the rotating shaft of the first movable roller and the other end engaging ratchet teeth on the inner surface of the first ratchet. The first spring is disposed inside the first ratchet, with one end fixedly connected to the rotating shaft of the first movable roller and the other end fixedly connected to the first pawl.

[0014] Furthermore, the anti-rotation gear includes a second ratchet, a second pawl, and a second spring. The axis of the second ratchet coincides with the axis of the second movable roller's rotational axis and is fixedly connected to the support plate, with its rotational axis coinciding with its own axis. The second pawl is disposed inside the second ratchet, with one end rotationally connected to the second movable roller's rotational axis and the other end engaging ratchet teeth on the inner surface of the second ratchet. The second spring is disposed inside the second ratchet, with one end fixedly connected to the second movable roller's rotational axis and the other end fixedly connected to the second pawl.

[0015] When it is necessary to cut the backboard film, the staff controls the driving motor to start through the controller, and the driving motor drives the reciprocating screw to rotate. The reciprocating screw first drives the two support plates to move backward, and the two support plates drive the first moving roller, the second moving roller, the first ratchet, the first pawl, the first spring, the second ratchet, the second pawl, the second spring, the two driven gears, the guide plate, the cutting knife, the two reset springs, and the two telescopic rods to move backward until the slider of the reciprocating screw moves to the end, and the first ratchet rotates under the action of the linkage rack, and the ratchet teeth on the inner surface of the first ratchet drive the first moving roller to rotate through the first pawl and the first spring, and the first moving roller drives the second moving roller to rotate through the two driven gears, and the second moving roller drives the second pawl and the second spring to rotate, and the second pawl continuously compresses and releases the second spring under the push of the ratchet teeth on the inner surface of the second ratchet. The first moving roller and the second moving roller rotate together to transport the backsheet film. The transport speed of the first moving roller and the second moving roller is the same as the moving speed of the slider of the reciprocating screw, so that the backsheet film gradually falls onto the collection platform, thereby realizing automatic uniform speed transport of the backsheet film, improving the cutting effect of the backsheet film and the flattening effect during collection.

[0016] When the slider of the reciprocating screw moves to the end, the driving motor continues to drive the reciprocating screw to rotate, and the reciprocating screw drives the two support plates to move forward. The two support plates drive the first moving roller, the second moving roller, the first ratchet, the first pawl, the first spring, the second ratchet, the second pawl, the second spring, the two driven gears, the guide plate, the cutting knife, the two return springs, and the two telescopic rods to move forward until the slider of the reciprocating screw moves to the front end. The first ratchet rotates in the opposite direction under the action of the linkage rack, and the ratchet teeth on the inner surface of the first ratchet push the first pawl to continuously compress and release the first spring, but will not drive the first moving roller to rotate.

[0017] The first moving roller and the second moving roller clamp the backsheet film, driving the backsheet film to move forward, which will drive the winding roller to rotate and unwind the backsheet film. At this time, the first moving roller and the second moving roller will be subjected to backward pulling force. The second ratchet, the second pawl, the second spring, and the two driven gears can prevent the first moving roller and the second moving roller from rotating, thereby realizing the transportation of the backsheet film and cutting the backsheet film to the specified length, thereby improving the quality of the cut backsheet film.

[0018] Furthermore, the conveying device includes a guide plate. The guide plate is disposed in front of the first and second movable rollers along the conveying direction and is tilted downward. The guide plate is fixedly connected to the two support plates. The line connecting the rotating axes of the first and second movable rollers is perpendicular to the guide plate.

[0019] The front end of the backsheet membrane falls onto the surface of the collecting platform under the guidance of the guide plate.

[0020] Furthermore, the cutting device includes two sliding openings, a cutting knife, two return springs, and two telescopic rods. The bottom surface of the linkage rack is tilted upward along the conveying direction. The two sliding openings are respectively tilted on the two support plates and perpendicular to the guide plate. The cutting knife passes through the two sliding openings and is slidably arranged in the two sliding openings, above the guide plate and below the linkage rack, and the top of the cutting knife abuts against the bottom surface of the linkage rack. The two telescopic rods are parallel to the two sliding openings and are respectively arranged in the two sliding openings, above the cutting knife. The upper ends of the two telescopic rods are respectively fixedly connected to the two support plates, and the lower ends are fixedly connected to the cutting knife. The two return springs are respectively sleeved on the outside of the two telescopic rods, the upper ends are respectively fixedly connected to the two support plates, and the lower ends are fixedly connected to the cutting knife.

[0021] As the cutter moves backward, it slides downward within the sliding opening, squeezed by the bottom surface of the linked rack, approaching the guide plate and the backing film. The cutter then extends the two return springs and telescopic rods. When the reciprocating screw's slider reaches its end, the cutter cuts the backing film, and the entire film falls onto the collection platform, automatically cutting the backing film to the specified length.

[0022] When the cutting knife moves forward, it moves in a direction away from the guide plate under the pull of the two return springs, and compresses the two telescopic rods until the cutting knife is reset.

[0023] By periodically implementing the above process of cutting to a specified length and automatically collecting the backsheet film, the quality, cutting efficiency and collection efficiency of the cut backsheet film are effectively improved.

[0024] A working method for photovoltaic module manufacturing equipment. When it is necessary to cut the backsheet film, the staff controls the drive motor to start through the controller. The drive motor drives the reciprocating screw to rotate. The reciprocating screw first drives the two support plates to move backward. The two support plates drive the first moving roller, the second moving roller, the first ratchet, the first pawl, the first spring, the second ratchet, the second pawl, the second spring, the two driven gears, the guide plate, and the cutting knife to move backward until the slider of the reciprocating screw moves to the end. The first ratchet rotates under the action of the linkage rack. The ratchet teeth on the inner surface of the first ratchet drive the first moving roller to rotate through the first pawl and the first spring. The first moving roller drives the second moving roller to rotate through the two driven gears. The second moving roller drives the second pawl and the second spring to rotate. The second pawl continuously compresses and releases the second spring under the push of the ratchet teeth on the inner surface of the second ratchet. The first moving roller and the second moving roller rotate together to transport the backsheet film, and then the front end of the backsheet film falls onto the surface of the collecting platform under the guidance of the guide plate. The conveying speed of the first moving roller and the second moving roller is the same as the moving speed of the slider of the reciprocating screw, so that the backsheet film gradually falls onto the collecting platform.

[0025] Furthermore, as the cutter moves backward, the cutter slides downward within the sliding opening under the pressure of the bottom surface of the linkage rack, approaching the guide plate and the backing film. The cutter drives the two return springs and two telescopic rods to extend. When the slider of the reciprocating screw moves to the end, the cutter cuts the backing film.

[0026] Beneficial effects of the present invention:

[0027] 1. When the backsheet film needs to be cut, the staff controls the moving device to move backward through the controller, and the moving device drives the conveying device to move backward. At the same time, the conveying device continuously conveys the backsheet film, and then cuts the backsheet film through the cutting device, so that the backsheet film falls onto the collecting device, thereby automatically cutting and collecting the backsheet film according to specifications.

[0028] 2. When it is necessary to cut the backboard film, the staff controls the driving motor to start through the controller, and the driving motor drives the reciprocating screw to rotate.

The conveying speed of the first moving roller and the second moving roller is the same as the moving speed of the slider of the reciprocating screw, so that the backsheet film gradually falls onto the collecting platform, thereby realizing automatic and uniform conveying of the backsheet film, improving the cutting effect of the backsheet film and the flattening effect during collection.

[0029] 3. The cutter moves backward, sliding downward within the sliding opening under the pressure of the bottom surface of the linkage rack, approaching the guide plate and the backing film. The cutter drives the two return springs and two telescopic rods to extend. When the slider of the reciprocating screw reaches the end, the cutter cuts the backing film, and the cut backing film falls to the surface of the collection platform, thus achieving automatic cutting of the backing film to the specified length.

[0037] When the backsheet film needs to be cut, the staff controls the moving device to move backward through the controller, and the moving device drives the conveying device to move backward. At the same time, the conveying device continuously conveys the backsheet film, and then the backsheet film is cut by the cutting device, so that the backsheet film falls onto the collecting device.

[0038] The collecting device includes a collecting platform 3 and a plurality of telescopic springs 31. The telescopic springs 31 are arranged vertically, and their lower ends are fixedly connected to the mounting frame 1. The collecting platform 3 is arranged horizontally above the telescopic springs 31 and is fixedly connected to their upper ends.

[0039] As the weight of the backsheet film on the collecting platform 3 increases, the telescopic springs 31 are gradually compressed, so that the top surface of the backsheet film on the collecting platform 3 always maintains an appropriate distance from the guide plate 512, thereby improving the collection effect of the backsheet film.

[0040] The moving device includes a reciprocating screw 42, an anti-rotation plate 4, and a drive motor 41. The anti-rotation plate 4 is positioned horizontally directly above the collection platform 3 and is fixedly connected to the mounting frame 1. The reciprocating screw 42 is positioned horizontally and along the conveying direction, located below the anti-rotation plate 4. Both ends of the reciprocating screw 42 are rotationally connected to the anti-rotation plate 4, with its rotation axis coinciding with its own axis. The slider of the reciprocating screw 42 is in close contact with the bottom surface of the anti-rotation plate 4. The rotating shaft of the drive motor 41 is coaxially fixedly connected to one end of the reciprocating screw 42. The drive motor 41 is fixedly connected to the anti-rotation plate 4 and is electrically connected to the controller.

[0041] The staff controls the driving motor 41 to start through the controller, and the driving motor 41 drives the reciprocating screw 42 to rotate, and the reciprocating screw 42 first drives the conveying device and the cutting device to move back and forth.

[0042] The conveying device includes a first movable roller 52, a second movable roller 56, a linkage gear, an anti-rotation gear, a linkage rack 43, two driven gears 513, and two support plates 5. The two support plates 5 are arranged vertically and parallel to the axis of the reciprocating screw 42. The two support plates 5 are arranged opposite to each other and are located below the anti-rotation plate 4. The upper ends of the two support plates 5 are fixedly connected to the slider of the reciprocating screw 42.

The two end shafts of the first movable roller 52 are respectively rotatably connected to the two support plates 5. The axis of the second movable roller 56 is parallel to the axis of the first movable roller 52, is located between the two support plates 5, and is located below the first movable roller 52. The two end shafts of the second movable roller 56 are respectively rotatably connected to the two support plates 5. The distance between the first movable roller 52 and the second movable roller 56 is adapted to the thickness of the backsheet film. Two driven gears 513 are located outside the two support plates 5 and are coaxially fixedly connected to the rotating shafts of the first and second movable rollers 52 and 56, respectively. The two driven gears 513 mesh with each other. A linkage gear, a ratchet structure, is located outside the two support plates 5 and connected to the rotating shaft of the first movable roller 52. A linkage rack 43 is parallel to the axis of the reciprocating screw 42 and located below the linkage gears. One end of the linkage rack 43 is fixedly connected to the anti-rotation plate 4, and the top of the linkage rack 43 meshes with the linkage gears. The anti-rotation gear, a ratchet structure, is located outside the two support plates 5, below the linkage rack 43, and connected to the rotating shaft of the second movable roller 56.

[0043] The linkage gear includes a first ratchet 51, a first pawl 54, and a first spring 53. The axis of the first ratchet 51 coincides with the axis of the rotation shaft of the first movable roller 52 and is rotationally connected to the support plate 5. Its rotation axis coincides with its own axis. The first ratchet 51 meshes with the top of the linkage rack 43. The first pawl 54 is disposed inside the first ratchet 51, with one end rotationally connected to the rotation shaft of the first movable roller 52 and the other end engaging the ratchet teeth on the inner surface of the first ratchet 51. The first spring 53 is disposed inside the first ratchet 51, with one end fixedly connected to the rotation shaft of the first movable roller 52 and the other end fixedly connected to the first pawl 54.

[0044] The anti-rotation gear includes a second ratchet 55, a second pawl 57, and a second spring 58. The axis of the second ratchet 55 coincides with the axis of the second movable roller 56. The second ratchet 55 is fixedly connected to the support plate 5, and its rotation axis coincides with its own axis. The second pawl 57 is located inside the second ratchet 55, with one end rotationally connected to the second movable roller 56's rotation axis and the other end engaging the ratchet teeth on the inner surface of the second ratchet 55. The second spring 58 is located inside the second ratchet 55, with one end fixedly connected to the second movable roller 56's rotation axis and the other end fixedly connected to the second pawl 57.

[0045] When it is necessary to cut the back sheet film, the staff controls the driving motor 41 to start through the controller, and the driving motor 41 drives the reciprocating screw 42 to rotate, and the reciprocating screw 42 first drives the two support plates 5 to move backward, and the two support plates 5 drive the first moving roller 52, the second moving roller 56, the first ratchet 51, the first pawl 54, the first spring 53, the second ratchet 55, the second pawl 57, the second spring 58, the two driven gears 513, the guide plate 512, the cutting knife 511, the two return springs 510, the two extension springs 511, the two guide springs 512, the two extension springs 513, the two extension springs 513, the two extension springs 514, the two extension springs 515, the two extension springs 516, the two extension springs 517, the two extension springs 518, the two extension springs 519, the two extension springs 520, the two extension springs 521, the two extension springs 522, the two extension springs 523, the two extension springs 524, the two extension springs 525, the two extension springs 526, the two extension springs 527, the two extension springs 528, the two extension springs 529, the two extension springs 530, the two extension springs 531, the two extension springs 532, the two extension springs The retracting rod 59 moves backward until the slider of the reciprocating screw 42 moves to the end. The first ratchet 51 rotates under the action of the linkage rack 43. The ratchet teeth on the inner surface of the first ratchet 51 drive the first moving roller 52 to rotate through the first pawl 54 and the first spring 53. The first moving roller 52 drives the second moving roller 56 to rotate through two driven gears 513. The second moving roller 56 drives the second pawl 57 and the second spring 58 to rotate. The second pawl 57 continuously compresses and releases the second spring 58 under the push of the ratchet teeth on the inner surface of the second ratchet 55. The first moving roller 52 and the second moving roller 56 rotate together to convey the backsheet film. The conveying speed of the first moving roller 52 and the second moving roller 56 is the same as the moving speed of the slider of the reciprocating screw 42, so that the backsheet film gradually falls onto the collection platform 3, thereby realizing automatic and uniform conveying of the backsheet film, improving the cutting effect of the backsheet film and the flattening effect during collection.

[0046] When the slider of the reciprocating screw 42 moves to the end, the driving motor 41 continues to drive the reciprocating screw 42 to rotate, and the reciprocating screw 42 drives the two support plates 5 to move forward. The two support plates 5 drive the first moving roller 52, the second moving roller 56, the first ratchet 51, the first pawl 54, the first spring 53, the second ratchet 55, the second pawl 57, the second spring 58, the two driven gears 513, the guide plate 512, the cutting knife 511, the two return springs 510, and the two telescopic rods 59 to move forward until the slider of the reciprocating screw 42 moves to the front end. The first ratchet 51 rotates in the opposite direction under the action of the linkage rack 43. The ratchet teeth on the inner surface of the first ratchet 51 push the first pawl 54 to continuously compress and release the first spring 53, but will not drive the first moving roller 52 to rotate.

[0047] The first moving roller 52 and the second moving roller 56 clamp the backboard film, driving the backboard film to move forward, which will drive the winding roller 2 to rotate and unwind the backboard film. At this time, the first moving roller 52 and the second moving roller 56 will be subjected to backward pulling force. Through the second ratchet 55, the second pawl 57, the second spring 58, and the two driven gears 513, the first moving roller 52 and the second moving roller 56 can be prevented from rotating, thereby realizing the transportation of the backboard film, and can also cut the backboard film to the specified length, thereby improving the quality of the cut backboard film.

[0048] The conveying device includes a guide plate 512. The guide plate 512 is arranged in front of the first and second movable rollers 52, 56 along the conveying direction and is tilted downward. The guide plate 512 is fixedly connected to the two support plates 5. The line connecting the rotation axis of the first and second movable rollers 52, 56 is perpendicular to the guide plate 512.

[0049] The front end of the backsheet film falls onto the surface of the collecting platform 3 under the guidance of the guide plate 512 .

[0050] The cutting device includes two sliding openings, a cutting blade 511, two return springs 510, and two telescopic rods 59. The bottom surface of the linkage rack 43 is tilted upward along the conveying direction. The two sliding openings are respectively arranged at an angle on the two support plates 5 and are perpendicular to the guide plate 512. The cutting blade 511 passes through the two sliding openings and slides within them, located above the guide plate 512 and below the linkage rack 43. The top of the cutting blade 511 abuts the bottom surface of the linkage rack 43. The two telescopic rods 59 are parallel to the two sliding openings and are respectively arranged within them, located above the cutting blade 511. The upper ends of the two telescopic rods 59 are fixedly connected to the two support plates 5, and the lower ends are fixedly connected to the cutting blade 511. The two return springs 510 are respectively mounted outside the two telescopic rods 59, with the upper ends fixedly connected to the two support plates 5 and the lower ends fixedly connected to the cutting blade 511.

[0051] As the cutting blade 511 moves backward, it slides downward within the sliding opening under the pressure of the bottom surface of the linkage rack 43, approaching the guide plate 512 and the backsheet film. The cutting blade 511 then extends the two return springs 510 and the two telescopic rods 59. When the slider of the reciprocating screw 42 reaches its end, the cutting blade 511 cuts the backsheet film, and the cut backsheet film falls entirely onto the surface of the collection platform 3, thereby automatically cutting the backsheet film to the specified length.

[0052] When the cutting blade 511 moves forward, it moves in a direction away from the guide plate 512 under the pull of the two return springs 510 and compresses the two telescopic rods 59 until the cutting blade 511 is returned to its original position.

[0053] By periodically implementing the above process of cutting to a specified length and automatically collecting the backsheet film, the quality, cutting efficiency and collection efficiency of the cut backsheet film are effectively improved.

[0054] A working method of a photovoltaic module manufacturing device. When it is necessary to cut the backsheet film, the staff controls the driving motor 41 through the controller to start, and the driving motor 41 drives the reciprocating screw 42 to rotate. The reciprocating screw 42 first drives the two support plates 5 to move backward, and the two support plates 5 drive the first moving roller 52, the second moving roller 56, the first ratchet 51, the first pawl 54, the first spring 53, the second ratchet 55, the second pawl 57, the second spring 58, the two driven gears 513, the guide plate 512, and the cutting knife 51. 1 moves backward until the slider of the reciprocating screw 42 reaches the end. The first ratchet 51 rotates under the action of the linkage rack 43. The ratchet teeth on the inner surface of the first ratchet 51 drive the first movable roller 52 to rotate through the first pawl 54 and the first spring 53. The first movable roller 52 drives the second movable roller 56 to rotate through two driven gears 513. The second movable roller 56 drives the second pawl 57 and the second spring 58 to rotate. The second pawl 57, driven by the ratchet teeth on the inner surface of the second ratchet 55, continuously compresses and releases the second spring 58. The first and second movable rollers 52 and 56 rotate together to convey the backsheet film. The front end of the backsheet film then falls onto the surface of the collection platform 3 under the guidance of the guide plate 512. The conveying speed of the first and second movable rollers 52 and 56 is the same as the movement speed of the slider of the reciprocating screw 42, so that the backsheet film gradually falls onto the collection platform 3.

[0055] As the cutting blade 511 moves backward, it slides downward in the sliding opening under the pressure of the bottom surface of the linkage rack 43, approaches the guide plate 512 and the back sheet film, and the cutting blade 511 drives the two return springs 510 and the two telescopic rods 59 to extend. When the slider of the reciprocating screw 42 moves to the end, the cutting blade 511 cuts the back sheet film.

[0056] Working process:

[0057] When it is necessary to cut the back sheet film, the staff controls the driving motor 41 to start through the controller, and the driving motor 41 drives the reciprocating screw 42 to rotate, and the reciprocating screw 42 first drives the two support plates 5 to move backward, and the two support plates 5 drive the first moving roller 52, the second moving roller 56, the first ratchet 51, the first pawl 54, the first spring 53, the second ratchet 55, the second pawl 57, the second spring 58, the two driven gears 513, the guide plate 512, the cutting knife 511, the two return springs 510, the two extension springs 511, the two guide springs 512, the two extension springs 513, the two extension springs 513, the two extension springs 514, the two extension springs 515, the two extension springs 516, the two extension springs 517, the two extension springs 518, the two extension springs 519, the two extension springs 520, the two extension springs 521, the two extension springs 522, the two extension springs 523, the two extension springs 524, the two extension springs 525, the two extension springs 526, the two extension springs 527, the two extension springs 528, the two extension springs 529, the two extension springs 530, the two extension springs 531, the two extension springs 532, the two extension springs The retracting rod 59 moves backward until the slider of the reciprocating screw 42 moves to the end. The first ratchet 51 rotates under the action of the linkage rack 43. The ratchet teeth on the inner surface of the first ratchet 51 drive the first moving roller 52 to rotate through the first pawl 54 and the first spring 53. The first moving roller 52 drives the second moving roller 56 to rotate through two driven gears 513. The second moving roller 56 drives the second pawl 57 and the second spring 58 to rotate. The second pawl 57 continuously compresses and releases the second spring 58 under the push of the ratchet teeth on the inner surface of the second ratchet 55. The first moving roller 52 and the second moving roller 56 rotate together to convey the backsheet film. After that, the front end of the backsheet film falls to the surface of the collection platform 3 under the guidance of the guide plate 512. The conveying speed of the first moving roller 52 and the second moving roller 56 is the same as the moving speed of the slider of the reciprocating screw 42, so that the backsheet film gradually falls onto the collection platform 3, thereby realizing automatic and uniform conveying of the backsheet film, improving the cutting effect of the backsheet film and the flattening effect during collection.

[0058] The cutting blade 511 moves backward and, squeezed by the bottom surface of the linkage rack 43, slides downward within the sliding opening, approaching the guide plate 512 and the backsheet film. The cutting blade 511 then causes the two return springs 510 and the two telescopic rods 59 to extend. When the slider of the reciprocating screw 42 reaches the end, the cutting blade 511 cuts the backsheet film, and the cut backsheet film falls entirely onto the surface of the collection platform 3, thereby automatically cutting the backsheet film to the specified length.

[0059] As the weight of the backsheet film on the collecting platform 3 increases, the telescopic springs 31 are gradually compressed, so that the top surface of the backsheet film on the collecting platform 3 always maintains an appropriate distance from the guide plate 512, thereby improving the collection effect of the backsheet film.

[0060] When the slider of the reciprocating screw 42 moves to the end, the driving motor 41 continues to drive the reciprocating screw 42 to rotate, and the reciprocating screw 42 drives the two support plates 5 to move forward. The two support plates 5 drive the first moving roller 52, the second moving roller 56, the first ratchet 51, the first pawl 54, the first spring 53, the second ratchet 55, the second pawl 57, the second spring 58, the two driven gears 513, the guide plate 512, the cutting knife 511, the two return springs 510, and the two telescopic rods 59 to move forward until the slider of the reciprocating screw 42 moves to the front end. The first ratchet 51 rotates in the opposite direction under the action of the linkage rack 43. The ratchet teeth on the inner surface of the first ratchet 51 push the first pawl 54 to continuously compress and release the first spring 53, but will not drive the first moving roller 52 to rotate.

[0061] The first moving roller 52 and the second moving roller 56 clamp the backboard film, driving the backboard film to move forward, which will drive the winding roller 2 to rotate and unwind the backboard film. At this time, the first moving roller 52 and the second moving roller 56 will be subjected to backward pulling force. Through the second ratchet 55, the second pawl 57, the second spring 58, and the two driven gears 513, the first moving roller 52 and the second moving roller 56 can be prevented from rotating, thereby realizing the transportation of the backboard film, and can also cut the backboard film to the specified length, thereby improving the quality of the cut backboard film.

[0062] At the same time, the cutting blade 511 moves forward and moves away from the guide plate 512 under the pull of the two return springs 510, and compresses the two telescopic rods 59 until the cutting blade 511 is reset.

[0063] By periodically implementing the above process of cutting to a specified length and automatically collecting the backsheet film, the quality, cutting efficiency and collection efficiency of the cut backsheet film are effectively improved.

[0064] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.
