Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a leather cutting device for leather shoe production. Background Technology

[0002] In the shoe manufacturing process, leather cutting is a crucial step that directly affects subsequent stitching, shaping, and the quality of the finished shoe. This is especially true for genuine leather, which has a natural fibrous structure and exhibits characteristics such as stretchability, uneven thickness (e.g., thinner edges, thicker center), and variations in grain direction. These factors place higher demands on cutting precision and process stability. In actual production, the cutting of key components such as the upper, vamp, and toe cap must strictly adhere to the design dimensions and grain direction to ensure the aesthetics, comfort, and structural strength of the finished shoe.

[0003] However, traditional leather cutting equipment typically uses manual placement or simple limiting structures for leather positioning, lacking a precise automatic positioning system. During the cutting process, the leather is prone to shifting or misalignment, especially when dealing with irregular shapes or complex shoe parts, making it difficult to achieve high-precision cutting, resulting in dimensional deviations in the cut pieces and affecting the quality of subsequent processing. Due to the low surface friction coefficient and uneven thickness of genuine leather, the pressing devices of traditional cutting equipment mostly use fixed pressure plates or simple pneumatic clamping structures, which cannot automatically adjust the pressure according to the thickness of the leather, resulting in uneven clamping force. This easily leads to problems such as leather slippage and wrinkling during the cutting process, affecting the cutting quality and consistency.

[0004] Therefore, there is an urgent need for a precise leather cutting device for shoe production. Utility Model Content

[0005] In order to overcome the shortcomings of inaccurate positioning in traditional leather cutting devices, the present invention aims to provide a leather cutting device for leather shoe production.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1: A leather cutting device for shoe production, such as Figures 1-3 As shown, the device includes a body 1, a worktable 2, a laser pointer 201, a rack 205, a gear 206, a slider 207, a guide rail 208, a conveyor belt 3, and a controller 5. Guide rails 208 are mounted on both sides of the body 1, and a slider 207 is slidably mounted on both guide rails 208. The slider 207 has an inverted U-shaped structure. Through the cooperation of the guide rails 208 and the slider 207, the worktable 2 can move back and forth. A rack 205 is mounted on the top of the slider 207, and the worktable 2 is slidably mounted on the slider 207. A rotating gear 206 is mounted on the worktable 2, which meshes with the rack 205 to drive the worktable 2, allowing it to move left and right on the slider 207. This enables precise positioning in four directions (front, back, left, and right) to ensure that the laser pointer 201 performs high-precision cutting according to the set trajectory. The laser pointer 201 is movably mounted on the bottom of the worktable 2, and a conveyor belt 3 is mounted on the machine body 1. A controller 5 is mounted on the left side of the machine body 1, and the controller 5 is electrically connected to the worktable 2, enabling it to control the laser pointer 201 and the gear 206 on the worktable 2.

[0023] When precise cutting of leather is required, the operator lays the leather to be cut flat on the conveyor belt 3. The leather is conveyed forward to the working area by the conveyor belt 3. At this time, the controller 5 controls the slider 207 to move back and forth along the guide rail 208 according to the preset cutting path and parameters, so that the worktable 2 connected to it moves accordingly. At the same time, through the meshing transmission of the gear 206 and the rack 205, the gear 206 rotates and moves left and right along the rack 205, driving the worktable 2 to move left and right accordingly. This achieves precise movement of the worktable 2 in four directions, so that the cutting position can be quickly adjusted according to specific needs to meet diverse production requirements. After cutting is completed, the conveyor belt 3 starts and transports the cut leather to the next process or collection area, realizing continuous and automated production, achieving a high degree of automation, reducing manual intervention, and speeding up production.

[0024] Example 2: Based on Example 1, such as Figures 1-4As shown, it also includes an adjustable connecting plate 202, a first elastic element 203, a drag chain 204, a pressure roller 4, a second elastic element 401, a scanner 501, and a guide plate 6. Auxiliary pressing rods are connected to both sides of the lower part of the worktable 2. A mounting rod is connected to the bottom of the worktable 2. The adjustable connecting plate 202 is slidably mounted on the mounting rod. The laser pointer 201 is movably mounted on the adjustable connecting plate 202. The first elastic element 203 is sleeved on the mounting rod. The upper end of the first elastic element 203 is connected to the bottom of the worktable 2, and the lower end is connected to the top of the adjustable connecting plate 202. This allows the laser pointer 201 to adaptively adjust according to the thickness of the leather material and maintain a stable fit under the action of the first elastic element 203, achieving flexible fitting and cutting of leather materials of different thicknesses, avoiding cutting deviations caused by inconsistent heights. A drag chain 204 is installed through the controller 5. The right end of the drag chain 204 is connected to the worktable 2, and the left end is connected to the machine body 1, allowing the worktable 2 to move left and right along the rack 205. The system serves to guide and protect the workbench 2, preventing gears 206 and racks 205 from shifting or jamming during left and right movements. Guide rods are installed on both sides of the machine body 1, with pressure rollers 4 slidably connected to them. A second elastic element 401 is fitted on each guide rod. The upper end of the second elastic element 401 is connected to the machine body 1, and the lower end is connected to the pressure roller 4, allowing the pressure roller 4 to automatically press down under the action of the second elastic element 401, pressing the leather flat and tightly onto the surface of the conveyor belt 3. This prevents the leather from slipping or wrinkling during the cutting process, improves cutting accuracy, and can automatically adapt to leather of different thicknesses to ensure uniform pressing force. A scanner 501 is installed on the front of the laser pointer 201. The controller 5 can preset multiple cutting modes. Combined with the scanner 501, it automatically identifies the texture and defect areas of the leather, optimizes the cutting path, reduces material waste, and improves the utilization rate of the leather. A guide plate 6 is installed at an angle on the rear of the machine body 1, which facilitates the guidance and collection of the cut leather.

[0025] When placing the leather material to prevent slippage during cutting, the operator can lift the pressure roller 4 upwards along the guide rod before the material enters the cutting area. Then, the material is placed between the pressure roller 4 and the conveyor belt 3. Subsequently, the pressure roller 4 automatically presses down under the action of the second elastic element 401, pressing the material flatly against the surface of the conveyor belt 3, thereby effectively preventing the material from slipping or wrinkling. During the laser cutting process, auxiliary pressing rods are also provided on both sides of the worktable 2, which can locally press the edges of the material during cutting, further improving cutting accuracy and stability. In addition, the laser pointer 201 can be adjusted up and down along the mounting rod via the adjustable connecting plate 202, and can achieve adaptive downward pressing under the action of the first elastic element 203, ensuring that the laser pointer 201 is stably attached to the surface of the material, improving cutting accuracy, especially suitable for leather materials of different thicknesses or with uneven surfaces.
