Description

Technical Field

[0001] The present invention belongs to the technical field of plastic bag recycling, and specifically relates to a recycling device for plastic packaging bag scraps. Background Art

[0002] In the production of plastic packaging bags, edge scraps generated during processes such as blown film, cast film, or printing and slitting need to be collected. Therefore, a recycling device for plastic packaging bag scraps is required to wind the waste edges into compact coils, facilitating subsequent crushing, melt granulation, or direct reuse.

[0003] A prior art document, a recycling device for plastic packaging bag scraps with the application number CN202211388388.8, includes a recycling pipe. A vibration cleaning assembly for removing foreign objects from the scraps is movably installed on the outer side of the recycling pipe. Two collecting gears are rotatably arranged in the middle of the recycling pipe. The two collecting gears are meshed and connected, and the plastic packaging bag scraps pass through the two collecting gears and enter the bottom of the recycling pipe. One end of one of the collecting gears is drivingly connected to a driving motor. During the recycling process of plastic packaging bag scraps, the present invention can remove foreign objects adsorbed on the plastic packaging bag scraps, ensuring the cleanliness of the recycling of plastic packaging bag scraps. In addition, the plastic packaging bag scraps can quickly cooperate with the collecting gears and complete the traction and recycling operation of the plastic packaging bag scraps, greatly improving the recycling efficiency of the plastic packaging bag scraps. To avoid interruption during the recycling process of plastic packaging bag scraps, the main method is traction and recycling through gear meshing. However, due to the thin and flexible nature of plastic bags, the gears are prone to squeezing and breaking the plastic bags, and the broken plastic bags are adsorbed and wound around the gears, affecting subsequent use. Therefore, it is necessary to optimize the existing edge material winding equipment to solve the problem of edge material breakage during the recycling process of plastic packaging bag scraps. Summary of the Invention

[0004] To solve the problem of edge material breakage during the recycling process of plastic packaging bag scraps proposed in the above background art, the present invention provides a recycling device for plastic packaging bag scraps.

[0005] To achieve the above object, the present invention provides the following technical solution: A recycling device for plastic packaging bag scraps, including a driving module. A mounting frame is fixedly connected to the side wall below the driving module. A guiding module is installed between the driving module and the mounting frame. A floating roller is fixedly connected to the guiding module. It further includes: A breakage remedy mechanism, which is commonly connected to the driving module and the mounting frame; A braking mechanism, which is installed between the driving module and the mounting frame; Among them, the breakage remedy mechanism includes a limiting member and a clamping member; The limiting member includes a dome-shaped sliding column, the outer wall of the dome-shaped sliding column slidably penetrates through the mounting frame, and an annular groove is formed on the outer wall of the dome-shaped sliding column near the dome.

[0006] Preferably, a swing rod is movably sleeved below the guiding module. Both ends of the swing rod are rotatably connected to a first fixing rod through pressing plates. Two ends of the first fixing rod are respectively fixed to the outer walls of the driving module and the mounting frame, and the outer wall of the pressing plate abuts against the dome-shaped sliding column.

[0007] Preferably, a collar is sleeved in the annular groove. A movable rod is fixed to the outer wall of the collar. The movable rod is slidably connected to the side wall of the mounting frame through a limiting sliding sleeve. The dome-shaped sliding column is elastically connected to the mounting frame through a first spring.

[0008] Preferably, the clamping member includes a vertical plate fixed to the top of the driving module. A second fixing rod is fixed between the vertical plate and the mounting frame. A moving rod is slidably connected between the vertical plate and the mounting frame. The moving rod is located obliquely below the second fixing rod. The top of the movable rod is rotatably connected to a chute rod.

[0009] Preferably, a sliding frame is fixed to the outer wall of the moving rod. The sliding frame is rotatably connected to the chute rod through a rotating shaft. The side wall of the mounting frame is rotatably connected to the side of the chute rod far from the rotating shaft.

[0010] Preferably, a support plate is fixed to the side wall of the mounting frame. The moving rod is elastically connected to the support plate through a second spring. The inner cavity of the sliding frame is slidably sleeved on the outer wall of the support plate.

[0011] Preferably, the braking mechanism includes a rack fixed to the middle of the movable rod. A gear is engaged with the outer wall of the rack. A rotating sleeve is fixed at the center of the gear. The rotating sleeve rotatably penetrates through the mounting frame.

[0012] Preferably, a telescopic rod is movably sleeved on the inner wall of the rotating sleeve. An inclined groove is formed on the outer wall of the telescopic rod. The rotating sleeve is slidably pressed in the inclined groove through a ball.

[0013] Preferably, a second rotating rod is fixed to one end of the telescopic rod close to the gear. A braking rod is sleeved on the second rotating rod through an annular block. One end of the braking rod far from the second rotating rod is fixed to a first rotating rod and is rotatably connected to the driving module through the first rotating rod.

[0014] Preferably, a winding module is rotatably connected to one side of the driving module. The floating roller winds up the plastic bag corner scraps through the winding module.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention facilitates timely remedial measures for broken edge materials by arranging the coordination of structures such as active rods and moving rods. Under normal working conditions, when the collar is in a locked position, the second spring always maintains a compressed energy storage state. Once the edge material breaks, the collar is unlocked by a large swing of the extrusion plate, and the active rod is linked to push the second spring to immediately release the elastic force, causing the moving rod to abut against the second fixed rod, clamping the broken edge material head at the first time, avoiding the elastic force from bouncing it far away and making it difficult to retrieve it, or stirring the edge material head into the slitting machine at the front end of the production line, causing machine failure, thereby shortening the time-consuming remedial process for the broken edge material.

[0016] The present invention facilitates timely braking of the winding module by arranging the coordination of structures such as the inclined groove, the ball and the brake rod. When the locking state is released, the movable rod moves along the inclined upward trajectory, which in turn causes the ball to squeeze the inclined groove and causes the brake rod to rotate in the opposite direction, thereby squeezing the floating roller through the brake rod, causing the floating roller to swing in the opposite direction, quickly and effectively braking the winding module, and stopping the winding process in time, making it easy for the staff to find another edge material head after the break from the sleeve, which is beneficial to the reconnection of the edge material after the break.

[0017] The present invention facilitates the simultaneous control of the two broken edge material heads by arranging the coordination of structures such as the dome slide column and the sleeve ring. During the normal winding process, the swing rod and the extrusion plate swing back and forth up and down, and the swing amplitude is always kept relatively consistent. When the edge material breaks, the downward swing amplitude of the extrusion plate will suddenly increase significantly, squeezing and impacting the dome position of the dome slide column, causing the dome slide column to shrink toward the inside of the mounting frame, thereby releasing the limit of the sleeve ring, and the movable rod located on the sleeve ring can simultaneously trigger the clamping function of the moving rod and the braking function of the floating roller, thereby effectively controlling the two broken edge material heads.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 12 shown, the present invention provides a plastic packaging bag scrap recycling device, including a driving module 1, a mounting frame 2 is fixedly connected to the lower side wall of the driving module 1, a guide module 4 is installed between the driving module 1 and the mounting frame 2, a floating roller 5 is fixedly connected to the guide module 4, and further includes: A fracture remedy mechanism 6, the driving module 1 and the mounting frame 2 are jointly connected with a fracture remedy mechanism 6; A braking mechanism 7, a braking mechanism 7 is installed between the driving module 1 and the mounting frame 2; Among them, the fracture remedy mechanism 6 includes a limiting member 61 and a clamping member 62; The limiting member 61 includes a dome-shaped sliding column 611. The outer wall of the dome-shaped sliding column 611 slidably penetrates through the mounting bracket 2. An annular groove 618 is formed on the outer wall of the dome-shaped sliding column 611 near the dome. A winding module 3 is rotatably connected to one side of the driving module 1. The floating roller 5 winds up the plastic bag corner materials through the winding module 3.

[0022] Adopting the above solution: The driving module 1 is mainly composed of a motor, transmission gears, a chain, a reduction box, etc., and is used to drive the winding module 3 to rotate and wind up the plastic bag edge materials. The winding module 3 is mainly composed of a winding shaft and a sleeve. The linear speed of winding needs to be synchronized with the slitter at the front section of the production line, and is used to cooperate with the floating roller 5 to wind up the plastic bag edge materials onto the sleeve. The guiding module 4 is mainly composed of guiding rollers, a magnetic powder brake, a rotating rod, a return spring, a positioning bracket and other structures. The guiding rollers are arranged parallel to the sleeve. The magnetic powder brake and the floating roller 5 are smoothly moved through the guiding rollers to correct the position of the edge materials. The plastic bag edge materials are hooked on the top of the floating roller 5. The floating roller 5 reciprocally swings on the rotating rod through the elastic force of the return spring. As Figure 1 shown, it is the feeding direction and the swinging direction of the floating roller 5. The change in the tension of the plastic bag edge materials is detected and adjusted in real time by the magnetic powder brake to ensure the normal winding process of the device. The above mechanisms are all existing technologies and will not be elaborated here.

[0023] As Figure 4 、 Figure 5 and Figure 9 shown, a swinging rod 614 is movably sleeved below the guiding module 4. Both ends of the swinging rod 614 are rotatably connected to a first fixing rod 613 through a pressing plate 617. Both ends of the first fixing rod 613 are fixedly connected to the outer walls of the driving module 1 and the mounting bracket 2 respectively. The outer wall of the pressing plate 617 abuts against the dome-shaped sliding column 611. A collar 615 is sleeved in the annular groove 618. A movable rod 616 is fixedly connected to the outer wall of the collar 615. The movable rod 616 is slidably connected to the side wall of the mounting bracket 2 through a limiting sliding sleeve. The dome-shaped sliding column 611 is elastically connected to the mounting bracket 2 through a first spring 612.

[0024] Adopting the above solution: The movable rod 616 is clamped between the pressing plate 617 and the mounting bracket 2. Since the collar 615 is sleeved on the outer wall of the dome-shaped sliding column 611 through the annular groove 618, it is difficult for the collar 615 to automatically disengage from the annular groove 618 when the dome-shaped sliding column 611 is stationary, ensuring a reliable mechanical interlock between the collar 615 and the annular groove 618 and basically eliminating the possibility of accidental disengagement, thereby providing a lasting and stable limiting function for the entire system.

[0025] As Figure 4 、 Figure 6 and Figure 10As shown in the figure, the clamping member 62 includes a vertical plate 621 fixedly connected to the top of the driving module 1. A second fixing rod 623 is fixedly connected between the vertical plate 621 and the mounting frame 2. A moving rod 622 is slidably connected between the vertical plate 621 and the mounting frame 2. The moving rod 622 is located obliquely below the second fixing rod 623. The top of the movable rod 616 is rotatably connected to a chute rod 625. A sliding frame 624 is fixedly connected to the outer wall of the moving rod 622. The sliding frame 624 is movably connected to the chute rod 625 through a rotating shaft 628. The side of the chute rod 625 away from the rotating shaft 628 is rotatably connected to the side wall of the mounting frame 2. A support plate 627 is fixedly connected to the side wall of the mounting frame 2. The moving rod 622 is elastically connected to the support plate 627 through a second spring 626. The inner cavity of the sliding frame 624 is slidably sleeved on the outer wall of the support plate 627.

[0026] With the above scheme: when the collar 615 is in the limit state, the second spring 626 is always in a compressed state. When the collar 615 is released from the limit, the elastic force of the second spring 626 squeezes the moving rod 622 to move in the direction of the second fixing rod 623, and drives the sliding frame 624 to move in the same direction through the moving rod 622. Then, the chute rod 625 is pulled through the annular groove 618, causing the chute rod 625 to rotate. The movable rod 616 located on the chute rod 625 can move obliquely upward, that is, in the direction of the second fixing rod 623, so as to trigger the braking mechanism 7 in the middle of the movable rod 616 to perform braking.

[0027] As Figure 4 、 Figure 7 and Figure 11 shown, the braking mechanism 7 includes a rack 75 fixedly connected to the middle of the movable rod 616. A gear 74 is meshed with the outer wall of the rack 75. A rotating sleeve 76 is fixedly connected to the center of the gear 74. The rotating sleeve 76 rotatably penetrates through the mounting frame 2.

[0028] As Figure 2 、 Figure 4 and Figure 12 shown, an expansion rod 77 is movably sleeved on the inner wall of the rotating sleeve 76. An inclined groove 78 is formed on the outer wall of the expansion rod 77. The rotating sleeve 76 is slidably pressed in the inclined groove 78 through a ball 79. One end of the expansion rod 77 close to the gear 74 is fixedly connected to a second rotating rod 73. The second rotating rod 73 is sleeved with a braking rod 71 through an annular block. One end of the braking rod 71 away from the second rotating rod 73 is fixedly connected to a first rotating rod 72 and is rotatably connected to the driving module 1 through the first rotating rod 72.

[0029] Adopting the above solution: when the edge material breaks, after the collar 615 is extruded and unlocked by the large swing of the extrusion plate 617, the movable rod 616 can rotate the gear 74 through the rack 75, and finally reverse-rotate the brake rod 71 through the ball 79. The large reverse rotation of the brake rod 71 extrudes the floating roller 5, causing the floating roller 5 to trigger the magnetic powder brake in the trigger guide module 4 to brake the sleeve of the winding module 3, preventing the sleeve of the winding module 3 from continuing to rotate and loosening the wound edge material. After testing, it can be ensured that the rotation angle of the sleeve of the winding module 3 after braking is <2°, and the interlayer slip of the coil is <0.1 mm, basically avoiding the phenomena of loose winding and collapsed winding.

[0030] The working principle and usage process of the present invention: First, before starting, first pass the edge material through the middle of the moving rod 622 and the second fixed rod 623, then hook it on the top of the floating roller 5, and finally fix it on the winding module 3. The floating roller 5 that swings reciprocally automatically adjusts the tension and corrects the position of the edge material to perform the edge material winding operation. During the process of the rotating rod reciprocally rotating due to the return spring on the guide module 4, the swinging rod 614 sleeved below can be synchronously reciprocally pulled. During the normal winding process, since the swinging rod 614 is movably sleeved on the first fixed rod 613 through the extrusion plate 617, the swinging rod 614 and the extrusion plate 617 will swing up and down reciprocally, and the swinging amplitude always remains relatively consistent. At this time, the extrusion plate 617 will not touch the dome slide post 611. However, when the edge material breaks, the floating roller 5 will generate a large driving moment under the action of inertia, resulting in a sharp increase in the swinging amplitude of the rotating rod. At this time, the downward swing amplitude of the extrusion plate 617 will suddenly increase significantly. When the extrusion plate 617 passes by the dome slide post 611, it will squeeze and impact the dome part of the dome slide post 611, causing the dome slide post 611 to contract towards the inside of the mounting bracket 2 and squeezing the first spring 612. At this time, the collar 615 loses the limit of the dome slide post 611 and the annular groove 618, prompting the movable rod 616 to move obliquely upward along the tension of the second spring 626, thereby releasing the limit and triggering the clamping and braking functions. At this time, the dome slide post 611 is reset by the first spring 612. After clamping the edge material and braking the winding module 3, the staff simultaneously pulls the collar 615 and the dome slide post 611, and manually snaps the collar 615 into the annular groove 618 for resetting for the next use; Secondly, in the normal working state, when the collar 615 is in the locked position, the second spring 626 always remains in a compressed energy storage state. Once the collar 615 is triggered by the pressing plate 617 to release the lock, the compressed second spring 626 immediately releases its elastic force, pushing the moving rod 622 to generate an axial displacement along the direction of the second fixed rod 623. After the moving rod 622 abuts against the second fixed rod 623, the broken edge material can be clamped immediately, thus preventing the edge material head from being caught in the slitter at the front section of the production line, effectively preventing machine failures, and promptly remedying the broken edge material. Then, the moving rod 622 synchronously drives the driven component, the sliding frame 624, to move in the same direction, and then drives the chute rod 625 to generate a rotational movement through the annular groove 618. As the chute rod 625 rotates, the movable rod 616 thereon moves along an obliquely upward trajectory, prompting the braking mechanism 7 of the braking component installed in the middle of the movable rod 616 to accurately trigger the braking action; Thirdly, when the collar 615 is released from the locked state, the associated movable rod 616 immediately moves along an obliquely upward trajectory as shown by the arrow in Figure 12 During this process, the rack 75 fixed to the middle of the movable rod 616 is displaced synchronously, causing the gear 74 to generate a meshing rotational movement. The rotating gear 74 transmits the torque to the ball 79 through the rotating sleeve 76, forcing the ball 79 to rotate synchronously. The rotational movement of the ball 79 squeezes the inclined groove 78, causing the telescopic rod 77 to rotate in the reverse direction opposite to the rotation direction of the gear 74. Then, the telescopic rod 77 drives the fixedly connected second rotating rod 73 to rotate in the reverse direction. Since the second rotating rod 73 is sleeved on the braking rod 71 through the ring block, the reverse rotation of the second rotating rod 73 can drive the braking rod 71 and the first rotating rod 72 to rotate in the reverse direction synchronously as shown by the rotating arrow in Figure 4 As a result, the floating roller 5 is squeezed by the braking rod 71, causing the floating roller 5 to swing significantly in the reverse direction, triggering the magnetic particle brake in the guiding module 4, braking the winding module 3, and promptly stopping the winding process. This facilitates the staff to find the other edge material head after fracture on the sleeve, then remove the edge material head from the moving rod 622 and the second fixed rod 623, quickly tie the two edge material heads, and continue the winding work, which is beneficial for reconnecting the edge material after fracture; Finally, the staff pulls the first spring 612 to socket the collar 615 into the annular groove 618, and the movable rod 616 moves along an obliquely downward movement trajectory. At the same time, the rack 75 is driven to move in the same direction. Contrary to the above operation, finally, the braking rod 71 is reset, facilitating the triggering and use for the next edge material fracture.
