[0031] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0032] Please refer to Figures 1 to 6 A device for tearing off and collecting waste films of plastic products, the main components of which include a plate conveyor 1. In detail, the plate conveyor 1 includes a frame 2, a conveying plate 3 and a driving device 4. The conveying plate 3 is installed on the frame 2, and is used to carry and convey plastic sheet products; and the driving device 4 is responsible for driving the conveying plate 3 to move forward. Specifically, the driving device 4 is composed of a driving shaft 43, a driven shaft 44 and a driving motor 45. The driving shaft 43 and the driven shaft 44 are both rotatably connected to the frame 2, and sprockets 46 are installed at both ends. The sprockets 46 on the same side are connected by a chain 47, and the conveying plate 3 is evenly installed on the chain 47. When the driving motor 45 is started, its output shaft drives the driving shaft 43 to rotate, and due to the transmission action of the chain 47, the conveying plate 3 will move forward accordingly.

[0033] Inside the conveying plate 3, a receiving groove 5 is provided for placing the plastic sheet product to be torn off. In order to facilitate loading, a clip-type silo can be installed on the frame 2 to realize automatic loading, or the product can be placed in the receiving groove 5 with the help of a manipulator.

[0034] In addition, a mounting frame 6 is also slidably installed on the frame 2 along the Z-axis direction. The mounting frame 6 is rotatably connected to the winding shaft 7, the unwinding shaft 8 and the adhesive roller 9. Among them, a winding motor 10 is fixed to one side of the winding shaft 7, and its output shaft is connected to one end of the winding shaft 7. The unwinding shaft 8 and the winding shaft 7 are respectively fixed with a tape unwinding roller 12 and a tape waste film winding roller 11. The tape is unwound from the tape unwinding roller 12, bypasses the adhesive roller 9, and is finally wound on the tape waste film winding roller 11. It is worth noting that the adhesive surface of the tape is set to face away from the adhesive roller 9, so that the adhesive surface of the tape can face outward and stick to the waste film on the surface of the plastic product.

[0035] In order to drive the mounting frame 6 to slide along the Z-axis direction, a mounting frame driving assembly 15 is also specially provided. The mounting frame 6 is connected to the guide rail 17 through the connecting arm 16, and the guide rail 17 is fixed on the frame 2. The connecting arm 16 slides on the guide rail 17, thereby driving the mounting frame 6 to move up and down. A support rod 18 is also fixed on the connecting arm 16, and a driving roller 19 is installed at the end of the support rod 18. The specific composition of the mounting frame driving assembly 15 includes a U-shaped groove 20 and a U-shaped protrusion 21, which are arranged on the conveying plate 3, and the ends of the U-shaped groove 20 and the U-shaped protrusion 21 are connected. When the driving roller 19 moves into the U-shaped groove 20 along the surface of the conveying plate 3, it will drive the mounting frame 6 and the adhesive roller 9 to descend together. When the adhesive roller 9 descends to contact one side of the plastic sheet product, the adhesive tape on it will stick to the waste film on the product. As the conveying plate 3 continues to move, the driving roller 19 will move along the U-shaped groove 20 toward the U-shaped protrusion 21. At this time, the mounting frame 6 and the bonding rod 9 will rise together, and the waste film will be gradually torn off the plastic sheet product.

[0036] In order to cooperate with the film tearing process, a clamping plate 13 and a clamping plate driving assembly 14 are also specially provided. The clamping plate 13 is slidably connected on the mounting frame 6 and cooperates with the bonding roller 9 to clamp the adhesive tape and the adhesive tape adhesive body. The clamping plate driving assembly 14 is responsible for driving the clamping plate 13 to slide along the X-axis direction. Specifically, the clamping plate 13 is connected to the mounting seat 22 through a transverse slider 23, and a return spring 24 is provided on one side of the transverse slider 23. When the third inclined portion 28 of the vertical slider 26 contacts the fourth inclined portion 31 of the driving plate 30 on the conveying plate 3, the vertical slider 26 will be raised, and then the first inclined portion 25 will be squeezed by the second inclined portion 27, so that the transverse slider 23 and the clamping plate 13 move together. After the second flat portion 32 of the driving plate 30 contacts the first flat portion 29 of the vertical slider 26, the clamping plate 13 will clamp one side of the adhesive tape and the waste film together with the bonding roller 9. As the conveying plate 3 continues to move, when the other third inclined portion 28 contacts the other fourth inclined portion 31 , the transverse slider 23 and the clamping plate 13 move in the opposite direction, and the clamping plate 13 is released.

[0037] In order to meet the film tearing requirements of products with different thicknesses and lengths, a bottom plate 35 and a length limiting plate 37 are specially provided. The bottom plate 35 is slidably connected in the receiving groove 5 along the Z-axis direction, and is connected to the conveying plate 3 through the lifting screw 36. The length limiting plate 37 is slidably connected on the bottom plate 35, and is connected to the slideway 38 in the conveying plate 3 through the length adjusting screw 39.

[0038] In addition, in order to keep the tape in a taut state, a swing arm 40, a tension adjustment rod 41 and a tension adjustment spring 42 are specially provided. The swing arm 40 is hinged on the mounting frame 6 through a rotating shaft, one end of the swing arm 40 is fixed with the tension adjustment rod 41, and the middle part is connected to the mounting frame 6 through the tension adjustment spring 42. At the same time, the unwinding shaft 8 is also rotatably connected to the mounting frame 6 through a damping bearing, providing a certain damping effect to prevent the tape from wrinkling and self-entanglement.

[0039] Finally, it is worth mentioning that in order to enhance the stability of the device, two connecting arms 16 and two guide rails 17 are provided. Such a design makes the entire device more stable and reliable during operation.

[0040] The side wall of the vertical slider 26 is provided with an anti-slip portion 33 , and the mounting seat 22 is provided with an anti-slip groove 34 , and the anti-slip portion 33 is slidably mounted in the anti-slip groove 34 , so that the vertical slider 26 can slide more stably.

[0041] Working principle:

[0042] Initial state:

[0043] The device is in a standby state, the conveying plate 3 is stationary, and the mounting frame 6 and the winding shaft 7, unwinding shaft 8, bonding roller 9 and other components thereon are all in the initial position.

[0044] The adhesive tape is unwound from the unwinding shaft 8 and bypasses the bonding roller 9, but does not come into contact with the waste film at this time.

[0045] The clamping plate 13 is in an open state and does not clamp the tape.

[0046] Loading and conveying:

[0047] The plastic sheet product is placed in the receiving groove 5 of the conveying plate 3 and can be automatically loaded through a clip-type silo or loaded by a robot.

[0048] The driving motor 45 is started, and the output shaft of the driving motor 45 drives the driving shaft 43 to rotate, and through the transmission of the sprocket 46 and the chain 47, the conveying plate 3 starts to convey the product forward.

[0049] Film peeling process:

[0050] As the conveying plate 3 is conveyed forward, the driving roller 19 moves from the surface of the conveying plate 3 into the U-shaped groove 20. Due to the guiding effect of the U-shaped groove 20, the mounting frame 6 and the bonding roller 9 descend together.

[0051] When the adhesive roller 9 descends to contact one side of the plastic sheet product, the adhesive surface of the adhesive tape adheres to the waste film on the plastic sheet product.

[0052] The product is continuously conveyed, and the driving roller 19 moves along the U-shaped groove 20 toward the U-shaped protrusion 21. At the same time, since the driving plate 30 on the conveying plate 3 contacts the third inclined portion 28 of the vertical slider 26, the vertical slider 26 rises, and then the first inclined portion 25 is pressed by the second inclined portion 27, so that the transverse slider 23 and the clamping plate 13 move together, clamping the tape and waste film.

[0053] When the waste film is completely torn off from the plastic sheet product, the clamping plate driving assembly 14 (through the contact between the second flattening portion 32 of the driving plate 30 and the first flattening portion 29) loosens the clamping plate 13. At this time, the winding motor 10 starts to work, sticking the waste film to the tape and winding it onto the tape waste film winding roller 11.

[0054] Adjustment and reset:

[0055] During the film tearing process, the lifting screw 36 and the length adjusting screw 39 can be adjusted according to the thickness and length of the product to adapt to products of different sizes.

[0056] The arrangement of the tension adjusting spring 42 and the damping bearing keeps the adhesive tape in a taut state, thereby preventing the adhesive tape from wrinkling and wrapping around itself.

[0057] When the product is conveyed or the film tearing needs to be stopped, the driving motor 45 stops working, the conveying plate 3 stops conveying, and the mounting frame 6 and the bonding roller 9 and other components are reset to the initial position under the action of gravity or the reset mechanism.

[0058] Continuous operation:

[0059] The device can operate continuously and realize an automated and efficient process of film tearing and waste film collection by constantly loading and conveying products.

[0060] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
