Description

Technical Field

[0001] This utility model relates to the technical field of fireproof coating construction equipment, specifically to a trimming device for cutting leather. Background Technology

[0002] Leather goods refer to various products made primarily of natural or artificial leather, such as bags and shoes. During the leather cutting process, the edges of leather often have irregular shapes, roughness, or uneven thickness. Trimming is done to remove excess or irregular parts, ensuring accurate dimensions and smooth edges, which facilitates subsequent sewing, gluing, and other processing steps, while also improving the aesthetics and structural strength of the finished product.

[0003] For example, application number 202420943970.4, entitled "A Trimming Device for Cutting Leather Goods," discloses a trimming device for cutting leather goods, including a trimming device base, a first mounting plate, a second mounting plate, and a trimming blade body. The first mounting plate is fixed to both sides of the trimming device base. The second mounting plate is slidably connected to the surface of the first mounting plate via a driving device. The trimming blade body is arranged in pairs on the lower surface of the second mounting plate. A working groove is formed on the lower surface of the second mounting plate, and a rotating rod is rotatably connected in the working groove. Through the cooperation of the rotating rod, spiral thread, fixing block, and driving motor, the trimming blade body can be adjusted to fit the leather material during trimming. The driving motor drives the rotating rod to rotate, allowing the rotating rod to move away from or closer to the spiral thread-driven fixing block, achieving a convenient adjustment effect and preventing the trimming blade body from being inconvenient to adjust when trimming leather material, thus affecting the user experience.

[0004] The shortcomings of existing technology are: when trimming leather goods, the position of the cutting blade needs to be adjusted according to the specific shape of the leather goods. In order to facilitate adjustment, the existing cutting blades are set on the same screw so that the cutting blades on both sides can be adjusted to move synchronously in opposite directions when rotating. This adjustment method has certain limitations. When cutting, it is necessary to ensure that the center line of the complete part of the leather goods is located at the center position of the two cutting blades, which has certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide a trimming device for cutting leather goods, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trimming device for cutting leather goods, including a processing table, a frame vertically and slidably connected to the processing table, two screws rotatably connected to the frame, a driven gear at one end of each screw, and trimming components on each screw; a moving plate vertically and slidably connected to the frame via an electric push rod, and a co-directional component and an opposing component on the moving plate.

[0007] The electric actuator drives the moving plate to have the following three stations:

[0008] At the first station, the moving plate moves down so that the unidirectional component contacts the two driven gears, so as to synchronously and unidirectionally adjust the position of the two cutting devices;

[0009] In the second station, the moving plate moves up so that neither the same-direction component nor the opposite-direction component comes into contact with the two driven gears, so that the positions of the two cutting devices can be adjusted individually.

[0010] In the third station, the moving plate continues to move upward so that the opposing components come into contact with the two driven gears, so as to synchronously adjust the positions of the two cutting devices.

[0011] As a further description of the above technical solution:

[0012] The co-directional component includes a gear 1 rotatably connected to a movable plate, which drives the movable plate to mesh with two driven gears during its travel.

[0013] As a further description of the above technical solution:

[0014] The opposing assembly includes gear two and gear three rotatably connected to the movable plate, and gear two and gear three mesh with each other. During the stroke of the movable plate, gear two is driven to mesh with the driven gear on one side, and gear three is driven to mesh with the driven gear on the other side.

[0015] As a further description of the above technical solution:

[0016] The cutting device includes a mounting block threaded onto a screw, and a cutting blade is provided at the bottom of the mounting block. A crossbar is also provided on the frame, and the mounting block is slidably connected to the crossbar.

[0017] As a further description of the above technical solution:

[0018] The frame is also provided with two sets of fabric pressing assemblies. The fabric pressing assembly includes an L-shaped plate fixedly connected to the frame, and a fabric pressing roller is provided between the two L-shaped plates on the same side.

[0019] As a further description of the above technical solution:

[0020] Both screws have a rotating handle at the other end.

[0021] In the above technical solution, the beneficial effects of the leather cutting and trimming device provided by this utility model are as follows:

[0022] This invention achieves flexible adjustment of the cutting blade position by setting up a liftable movable plate and its unidirectional and opposing components, combined with an electric actuator to control the movable plate in three different positions. In the first position, the unidirectional component enables the two cutting blades to move synchronously in the same direction, adapting to the overall offset of the leather edge. In the second position, the two cutting blades can be adjusted independently, which is convenient for dealing with asymmetrical or special-shaped leather goods. In the third position, the opposing component enables the two cutting blades to move synchronously in opposite directions, which is suitable for standard symmetrical cutting. This structure effectively overcomes the limitations of traditional edge trimming devices, such as the single adjustment method and high centering requirements, significantly improving the adaptability and efficiency of edge trimming operations, while ensuring cutting accuracy and the quality of finished leather goods.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0032] Please see Figure 1-3 This embodiment provides a leather trimming device for cutting leather goods, including a processing table 1. A frame 2 is vertically slidably connected to the processing table 1. The frame 2 on the processing table 1 is driven to move up and down by an external drive source. The movement of the frame 2 facilitates the placement of the leather goods to be processed on the processing table 1 for processing. Two screws 3 are rotatably connected to the frame 2. One end of each screw 3 is provided with a driven gear 4, and each screw 3 is provided with a trimming component. The other end of each screw 3 is provided with a rotating handle 15. Both ends of the two screws 3 extend to the outside of the frame 2. The driven gear 4 and the rotating handle 15 are located at the ends of the screws 3 extending to the outside of the frame 2, with the two driven gears 4 located on the same side and the two rotating handles 15 located on the other side. A moving plate 6 is vertically slidably connected to the frame 2 via an electric push rod 5. The electric push rod 5 is connected to an external power source and a control switch. After the electric push rod 5 is de-energized, it maintains the state before the power de-energization. The moving plate 6 of the electric push rod 5 is provided with a co-directional component and a counter-directional component. The electric push rod 5 drives the moving plate 6. The device 6 has three working stations: In the first station, the moving plate 6 moves downwards so that the unidirectional component contacts the two driven gears 4, allowing for synchronous and unidirectional adjustment of the positions of the two cutting devices; in the second station, the moving plate 6 moves upwards so that neither the unidirectional nor the opposing component contacts the two driven gears 4, allowing for individual adjustment of the positions of the two cutting devices; in the third station, the moving plate 6 continues to move upwards so that the opposing component contacts the two driven gears 4, allowing for synchronous and opposing adjustment of the positions of the two cutting devices. By setting a liftable moving plate 6 and its unidirectional and opposing components, combined with the electric push rod 5 controlling the moving plate 6 in three different working stations, flexible adjustment of the cutting blade 11 position is achieved. In the first station, the unidirectional component allows the two cutting blades 11 to move synchronously and in the same direction, adapting to the overall offset of the leather edge; in the second station, the two cutting blades 11 can be adjusted independently, facilitating the handling of asymmetrical or specially shaped leather goods; in the third station, the opposing component enables the two cutting blades 11 to move synchronously and opposingly, suitable for standard symmetrical cutting.

[0033] In a further embodiment of this utility model, the co-directional component includes a gear 7 rotatably connected to the movable plate 6. During the stroke of the movable plate 6, the gear 7 is driven to mesh with two driven gears 4 respectively. The opposing component includes a gear 8 and a gear 9 rotatably connected to the movable plate 6, and the gear 8 and gear 9 mesh with each other. During the stroke of the movable plate 6, the gear 8 is driven to mesh with a driven gear 4 on one side, and the gear 9 is driven to mesh with a driven gear 4 on the other side. The gears 7, 8, and 9 are all rotatably located on one side of the movable plate 6 via shafts and are on the same plane as the driven gears 4 on the screw 3. There is a certain gap between the gears 7, 8, and 9 so that when the movable plate 6 moves to the second position, the driven gears 4 on the screw 3 do not mesh with the gears 7, 8, or 9.

[0034] In a further embodiment of this utility model, the cutting device includes a mounting block 10 threadedly connected to the screw 3, and a cutting blade 11 is provided at the bottom of the mounting block 10. A crossbar 12 is also provided on the frame 2. The mounting block 10 is slidably connected to the crossbar 12. By providing the crossbar 12, the movement of the mounting block 10 is restricted, so that when the screw 3 rotates, it cooperates with the crossbar 12 to drive the mounting block 10 to drive the cutting blade 11 to move laterally for adjustment.

[0035] In the embodiments provided by this utility model, two sets of pressing cloth assemblies are also provided on the frame 2. The pressing cloth assembly includes an L-shaped plate 13 fixedly connected to the frame 2. A pressing cloth roller 14 is provided between the two L-shaped plates 13 on the same side. Under the support of the L-shaped plates 13, the pressing cloth roller 14 presses the leather as the frame 2 moves down, effectively preventing the leather from shifting or wrinkling during cutting, and ensuring the stability of the cutting process and the straightness of the cutting lines.

[0036] During operation, the operator first lays the leather goods to be cut flat on the processing table 1, and then starts the electric push rod 5 to adjust the moving plate 6 to the corresponding working position according to the cutting requirements.

[0037] When it is necessary to move the two cutting blades 11 synchronously and in the same direction to adjust the cutting width while keeping the center position unchanged (for example, when processing leather with parallel edges but uneven width), the electric push rod 5 is operated to lower the moving plate 6 to the first position. At this time, the gear 7 on the moving plate 6 meshes with the driven gear 4 at the ends of the two screws 3. By rotating any rotating handle 15, the power is transmitted through the driven gear 4 and the gear 7, causing the two screws 3 to rotate synchronously and in the same direction. The rotation of the screws 3 drives the mounting block 10, which is threaded to it, to slide synchronously and in the same direction along the crossbar 12, thereby realizing the synchronous and unidirectional position adjustment of the two cutting blades 11.

[0038] When the leather goods are irregular or asymmetrical and require fine adjustment of the position of the cutting blade 11 on one side, the electric push rod 5 is operated to raise the moving plate 6 to the second position. In this position, the same-direction component (gear 1 7) and the opposite-direction component (gear 2 8, gear 3 9) on the moving plate 6 are disengaged from the two driven gears 4, and the transmission connection of the two screws 3 is released. The operator can rotate the rotating handles 15 on both sides to make the two screws 3 rotate independently, thereby driving their respective mounting blocks 10 and cutting blades 11 to move independently, so as to achieve individual and precise position adjustment.

[0039] When standard symmetrical cutting is required, the electric push rod 5 is operated to make the moving plate 6 continue to rise to the third station. At this time, the opposing components start to work: gear 2 8 meshes with the driven gear 4 on one side, gear 3 9 meshes with the driven gear 4 on the other side, and gear 2 8 and gear 3 9 maintain their own meshing state. At this time, rotating any rotating handle 15 will transmit power through the driven gear 4, gear 2 8 and gear 3 9, causing the two screws 3 to rotate synchronously in opposite directions. The rotation of the screws 3 drives the two mounting blocks 10 to move synchronously in opposite directions along the crossbar 12 with the cutting blade 11.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
