Description

Technical Field

[0001] The present application relates to the technical field of leather release paper processing, and in particular to a leather release paper trimming and recycling device. Background Art

[0002] Leather release paper, as an important industrial material, is widely used in leather processing and other fields. It typically consists of a paper base and a film secured to the base. The production process involves multiple steps, including blank feeding, extrusion lamination, cutting, and winding. After the paper and film are extruded and laminated, excess film often remains at the edges of the finished product. This requires trimming to ensure the desired size and shape.

[0003] In the related art, a conventional leather release paper trimming system includes a base with a tensioning roller and a take-up roller mounted side by side. The tensioning roller maintains proper tension during the transport of the leather release paper, ensuring accurate cutting; the take-up roller winds up the cut leather release paper. Furthermore, cutting blades are mounted above each end of the tensioning roller. As the leather release paper passes over the tensioning roller, the two cutting blades trim the edges of the paper, removing any excess material and completing the trimming process.

[0004] Because the cut scrap edges also contain a significant amount of film, to reduce costs, factories typically remelt and recycle the remaining film protruding from the scrap. This results in the need for dedicated staff to re-cut and separate the paper scrap edges and the remaining protruding film during the subsequent waste sorting and recycling process. However, paper has a certain degree of flexibility and irregularities, while film is relatively thin and prone to adhesion. This results in not only low efficiency but also increased labor and time costs, affecting the efficiency of the entire production process, leaving room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a leather release paper trimming and recycling device to solve the problem in the above-mentioned related art that it is inconvenient to recycle the protruding film in the waste material.

[0006] The present application provides a leather release paper trimming and recycling device that adopts the following technical solution: A leather release paper trimming and recycling device comprises a base, a tensioning member for tightening the leather release paper, and a traction member for pulling the leather release paper, two brackets for supporting the tensioning member are relatively fixed to the upper surface of the base, and the traction member is used to drive the tightened leather release paper to feed in a vertical downward direction; an upper support plate and a lower support plate located below the upper support plate are fixed on the vertical side surface of the bracket, a cutting member for cutting the protruding edge of the film is installed on the upper support plate, and a trimming member for trimming the edge of the leather release paper after the edge of the film is cut is provided on the lower support plate; a recycling component for recycling film waste and leather release paper edge waste respectively is provided on the base.

[0007] By employing this technical solution, the tensioning and pulling elements work together to ensure that the leather release paper maintains stable tension during transport and feeds vertically downward, providing the foundation for precise cutting. The cutting and trimming elements work together to first trim the protruding edges of the film and then further trim the edges of the cut leather release paper, ensuring the accuracy and quality of the trimming. Most importantly, the design of the recycling component allows for the effective collection of film waste and leather release paper edge waste separately, avoiding the tedious process of manual sorting and cutting required by traditional methods. This significantly improves recycling efficiency and reduces labor and time costs.

[0008] Optionally, the tensioning member includes a first tensioning roller and a second tensioning roller which are rotatably connected to two brackets at both ends in the horizontal direction. The first tensioning roller is located above the second tensioning roller, and a driving member for driving the second tensioning roller to rotate is fixed on the outer side of the bracket.

[0009] By employing this technical solution, the first tensioning roller is positioned above the second tensioning roller, creating a rational tension transmission path. This helps maintain uniform and appropriate tension on the leather release paper during transport, which is crucial for the accuracy of subsequent cutting and trimming. A drive element positioned on the outside of the bracket specifically drives the second tensioning roller, integrating active traction and tensioning functions, simplifying the device structure and improving transmission efficiency. This design ensures smooth and continuous movement of the leather release paper during transport, reducing cutting errors caused by uneven tension or poor transmission, and ensuring high-quality trimming.

[0010] Optionally, the recycling component includes a first recycling pipe, a second recycling pipe and an air pump located above the base, the first recycling pipe is provided with a first feed inlet for placing waste, and first discharge ports are provided at both ends of the first recycling pipe; the second recycling pipe is provided with a second feed inlet for placing waste, and second discharge ports are provided at both ends of the second recycling pipe; the air pump is provided with a first air pipe connected to the middle of the first recycling pipe and a second air pipe connected to the middle of the second recycling pipe, the air pump drives the waste in the first recycling pipe to be discharged from the first discharge port, and the waste placed in the second recycling pipe to be discharged from the second discharge port.

[0011] By adopting the above technical solution, the first recovery pipe and the second recovery pipe respectively collect film waste and leather release paper edge waste. This classified recycling method avoids the mixing of waste materials and facilitates subsequent reuse and processing. The air pump is connected to the middle of the recovery pipe through the first and second air pipes, using airflow power to suck the waste from the feed port and discharge it from the discharge port, realizing the automated transportation of waste, reducing manual intervention, and improving recycling efficiency. At the same time, the airflow conveying method also avoids the blockage or damage problems that may be caused by traditional mechanical conveying, ensuring smooth waste recycling. In addition, the design has a compact structure and is easy to integrate into existing production lines, which not only saves space but also reduces modification costs.

[0012] Optionally, the cutting piece includes a fixed rod and a cutting knife fixed to one end of the fixed rod, the end of the fixed rod away from the cutting knife is rotatably connected to the upper surface of the upper support plate, and the upper support plate is provided with a first driving source that drives the fixed rod to be rotatably connected and fixed.

[0013] By adopting this technical solution, a cutting blade is fixed to one end of the fixed rod, while the other end is rotatably connected to the upper support plate. This design allows the cutting blade's angle to be adjusted according to actual production needs to accommodate the cutting of leather release paper of varying specifications or materials, improving the device's versatility and cutting accuracy. The provision of a first drive source drives the fixed rod to rotate and secure it in the desired position, ensuring the stability of the cutting blade during the cutting process, avoiding cutting errors caused by the cutting blade's shaking, and guaranteeing trimming quality.

[0014] Optionally, the trimming member includes a mounting plate located above the lower support plate, a second driving source that drives the mounting plate to slide back and forth in a horizontal direction, the mounting plate is located on the side of the second driving source close to the tensioning member, and a trimming wheel is rotatably mounted on the mounting plate, and a third driving source is fixed to drive the trimming wheel to rotate.

[0015] By adopting this technical solution, the mounting plate slides back and forth horizontally driven by the second drive source, allowing the trimming wheel to flexibly adjust its position as needed to accommodate the trimming of leather release paper of varying widths and shapes, enhancing the device's flexibility and versatility. The trimming wheel is rotatably mounted on the mounting plate and driven by the third drive source. This design ensures stability and continuity during the trimming process, enabling quick and accurate removal of excess leather release paper edges, improving trimming quality and efficiency.

[0016] Optionally, a blocking plate for protecting the cutting knife is rotatably provided on the outer periphery of the fixing rod, and a locking member for fixing the rotational state of the blocking plate is provided on the outside of the fixing rod; the blocking plate can be rotated to a state parallel to the fixing rod, and in this state, the blocking plate is close to the end of the cutting knife to block the cutting knife.

[0017] By adopting this technical solution, when the device is not powered on or in idle mode, the barrier plate can be rotated to a position parallel to the fixed rod. Its end near the cutting knife effectively blocks the cutting knife, preventing injury to unintentional personnel from accidentally touching it, significantly reducing the risk of safety accidents. This design not only demonstrates a high level of attention to operator safety, but also achieves efficient protection through a simple mechanical structure, enabling switching between protective modes without complex operations. Furthermore, the provision of a locking member ensures the stability of the barrier plate in the protective mode, preventing accidental movement due to vibration or external forces.

[0018] Optionally, the locking member includes a locking block, one side of which is provided with a locking notch for the blocking plate and the edge of the fixing rod in a parallel state to be placed together, an elastic clip is provided on the inner wall of the locking notch, and positioning grooves for the elastic clip to be inserted into are provided on the opposite side surfaces of the fixing rod.

[0019] By adopting this technical solution, the locking notch in the locking block precisely accommodates the parallel edges of the barrier plate and the fixed rod, ensuring a tight fit and stable positioning between them. The elastic clips on the inner wall of the locking notch cooperate with the positioning grooves on both sides of the fixed rod. Through this elastic snap-fit, the locking block is securely fixed to the fixed rod, effectively preventing the barrier plate from accidentally rotating or loosening. This design is not only simple in structure and easy to operate, but also provides a reliable locking effect, greatly improving the stability of the barrier plate in its protective state and providing a reliable safety barrier for the cutting knife.

[0020] Optionally, a protective cover for protecting the trimming wheel is provided on the outside of the mounting plate in a horizontal sliding direction, and the protective cover can slide back and forth in the horizontal direction; a control member that can make the protective cover slide in the direction away from the trimming wheel and an elastic extrusion member that drives the protective cover to slide in the direction close to the trimming wheel are provided on the mounting plate; the end of the blocking plate close to the fixed rod is also slid on the fixed rod and can slide back and forth along the length direction of the fixed rod; the blocking plate can be fixed in the state by a locking member when it is rotated to a vertical state, and when the blocking plate is in this state, it moves up and down with the rotation of the fixed rod, and when the trimming wheel moves in the direction away from the second driving source, the protection of the trimming wheel can be released by the action of the blocking plate on the control member.

[0021] By adopting the above technical solution, the protective cover design effectively covers the trimming wheel through a sliding mechanism, preventing accidental contact by the operator and enhancing the safety of the equipment during operation. The combination of the control element and the elastic extrusion element allows the protective cover to automatically open and close as needed, ensuring both effective protection and simplified operation. The barrier plate can not only slide and adjust its position on the fixed rod, but can also be fixed in a vertical state with a locking element, moving up and down as the fixed rod rotates. This feature allows the barrier plate to act on the control element during specific operations, automatically releasing the protection of the trimming wheel, and realizing an intelligent linkage between protection and operation.

[0022] Optionally, a positioning rod is fixed on the side of the protective cover facing the second driving source, and the elastic extrusion member includes a first spring, a guide block and a baffle fixed on the outer periphery of the positioning rod; the guide block is fixed on the side of the mounting plate facing the protective cover, the baffle is located on the side of the guide block facing the protective cover, and a positioning hole for the positioning rod to pass through is provided on the guide block, and the two ends of the first spring are respectively fixedly connected to the sides of the guide block and the baffle close to each other.

[0023] By adopting the above technical solution, the coordinated design of the protective cover and the elastic extrusion member significantly improves the protective performance and operational convenience of the device. The positioning rod is fixed to the side of the protective cover facing the second drive source, and precisely matches the positioning hole on the guide block, ensuring the stability of the protective cover during the sliding process and avoiding deviation or shaking. The first spring serves as the core part of the elastic extrusion member, and its two ends are fixedly connected to the guide block and the baffle respectively. The elastic restoring force of the spring is used to enable the protective cover to automatically slide toward the direction close to the trimming wheel when no external force is applied, thereby maintaining the protective state. This design not only simplifies the operation process of the protective cover, but also ensures the timeliness and effectiveness of the protection through the automatic reset function of the spring.

[0024] Optionally, the control member includes a control protrusion fixed on the side of the protective cover away from the mounting plate. When the blocking plate is in a vertical state, it is located on the side of the control protrusion away from the second driving source. When the mounting plate moves toward the side away from the second driving source, the blocking plate is pressed against one side of the control protrusion.

[0025] By adopting the above-mentioned technical solution, the control cam is fixed to the side of the protective cover away from the mounting plate. Its position corresponds to the blocking plate in the vertical state, forming a mechanical trigger mechanism. When the mounting plate moves toward the side away from the second drive source, the blocking plate moves with it and presses against one side of the control cam. This action directly acts on the control cam, which in turn pushes the protective cover to slide and release the protection of the trimming wheel. This design is not only simple in structure and responsive, but also does not require additional electrical or hydraulic systems, reducing costs and improving reliability. At the same time, the mechanical linkage control also reduces the possibility of misoperation and ensures that the protective cover can be opened accurately and promptly when needed, which not only protects the operator's safety but also improves work efficiency.

[0026] In summary, this application has the following beneficial technical effects: The cutting and trimming components work together to first trim the protruding film edges, then further trim the cut leather release paper edges, ensuring precise and high-quality trimming. Crucially, the recycling component's design allows for the separate and effective collection of film waste and leather release paper waste, eliminating the tedious manual sorting and cutting required by traditional methods. This significantly improves recycling efficiency and reduces labor and time costs. BRIEF DESCRIPTION OF THE DRAWINGS

After the film waste and leather release paper edge waste are cut into long strips, air is injected into the recovery assembly 6's air pump 63 through the first and second air pipes 632, and discharged and collected from the first and second recovery pipes 62, respectively.

[0037] Example 2: Reference Figure 4 、 Figure 5 and Figure 6The embodiment of the present application differs from the embodiment 1 in that a protective assembly 7 is provided on the outer periphery of the fixed rod 41, wherein the protective assembly 7 includes a blocking plate 71 having one end rotatably connected to the outer periphery of the fixed rod 41 for protecting the cutting blade 42, wherein a locking member 72 is provided on the outside of the fixed rod 41 for fixing the rotational state of the blocking plate 71; When the device is in use, the blocking plate 71 is rotated to a vertical state to release the protection of the cutting knife 42; when the device is not turned on, the staff can rotate the blocking plate 71 to a state parallel to the fixing rod 41 and fix it with the locking member 72. In this state, the end of the blocking plate 71 close to the cutting knife 42 can block and protect the cutting knife 42, reducing the possibility of unauthorized persons being scratched by the blade of the cutting knife 42 when the device is not turned on.

[0038] Reference Figure 5 , Figure 6 and Figure 7 The locking member 72 includes a locking block 721. A locking notch 7211 is provided on one side of the locking block 721 for the parallel edges of the blocking plate 71 and the fixing rod 41 to be placed together.

The compression spring 7221 presses one side of the arc-shaped protrusion 7222 so that a part of the arc-shaped protrusion 7222 protrudes from the opening of the placement groove 7212. The protruding part of the arc-shaped protrusion 7222 is an arc surface, and the arc length corresponding to the arc surface is a minor arc.

[0039] Refer to 6 and Figure 8 A protective cover 73 is provided on the outside of the mounting plate 51 to slide horizontally for protecting the trimming wheel 53, wherein the protective cover 73 can slide back and forth horizontally toward the tensioning member 2; a control member 74 is provided on one side of the mounting plate 51 to enable the protective cover 73 to slide away from the trimming wheel 53, and an elastic extrusion member 75 is provided to drive the protective cover 73 to slide toward the trimming wheel 53; The blocking plate 71 is rotatably connected to the fixed rod 41, and the end of the blocking plate 71 close to the fixed rod 41 is also slidably provided on the fixed rod 41 (by a combination of a slider and a slide groove), and can slide back and forth along the length direction of the fixed rod 41; when the blocking plate 71 is rotated to a vertical state, the state can be fixed by the locking member 72 (so that the blocking plate 71 can only slide back and forth up and down at this time). When the blocking plate 71 is in this state, it moves up and down with the rotation of the fixed rod 41. When the trimming wheel 53 moves away from the second driving source 52, the protection of the trimming wheel 53 can be released by the action of the blocking plate 71 on the control member 74.

[0040] Reference Figure 8 and Figure 9 The locking notch 7211 of the locking block 721 is inserted into the positioning slot 121, and the elastic clip 722 is snapped into the corresponding first groove 122. At this time, a part of the blocking plate 71 is snapped into the corresponding locking notch 7211, so that the locking block 721 is used to guide and limit the vertical blocking plate 71.

[0041] Reference Figure 8 and Figure 10 A positioning rod 731 is fixedly provided on the side of the protective cover 73 facing the second driving source 52, wherein the elastic extrusion member 75 includes a first spring 751, a guide block 752 and a baffle 753 fixed on the outer periphery of the positioning rod 731; the guide block 752 is fixed on the side of the mounting plate 51 facing the protective cover 73, and the baffle 753 is located on the side of the guide block 752 facing the protective cover 73.

The two ends of the first spring 751 are respectively fixedly connected to the side surfaces of the guide block 752 and the protective cover 73 that are close to each other.

[0042] Reference Figure 8 The control member 74 includes a control protrusion 741 fixed on the side of the protective cover 73 away from the mounting plate 51. When the blocking plate 71 is in a vertical state, it is located on the side of the control protrusion 741 away from the second driving source 52. When the mounting plate 51 moves toward the side away from the second driving source 52, the blocking plate 71 is pressed against one side of the control protrusion 741.

[0043] The implementation principle of the embodiment of this application is: When the machine is not powered on: A worker rotates the baffle plate 71 until it is parallel to the fixing rod 41 and secures it with the locking member 72. The locking block 721 of the locking member 72 inserts into the positioning slot 121 of the upper support plate 12, and the elastic engaging member 722 engages the first groove 122, guiding and limiting the baffle plate 71 so that it blocks and protects the cutting blade 42, reducing the possibility of scratches on unauthorized personnel. Simultaneously, the protective cover 73, under the action of the elastic extrusion member 75, slides toward the trimming wheel 53, covering it and providing additional protection.

[0044] During operation, the operator unlocks the blocking plate 71, rotates it to a vertical position, and secures it again, allowing it to move up and down as the fixing rod 41 rotates. As the trimming wheel 53 moves away from the second drive source 52, the blocking plate 71 acts on the control member 74, releasing the protection provided by the trimming wheel 53 and allowing it to operate normally. At this point, the cutting blade 42 and trimming wheel 53 can respectively cut and trim the leather release paper, completing the trimming operation.
