Description

Technical Field

[0001] This invention relates to the field of leather shoe upper production technology, specifically to an automatic cutting device for leather shoe upper production. Background Technology

[0002] In the production of leather shoe uppers, efficient and precise cutting processes are key to ensuring product quality and production efficiency. Traditional leather shoe upper cutting methods rely heavily on manual operation, which is not only labor-intensive but also significantly affected by human factors in terms of cutting accuracy. Manual cutting makes it difficult to guarantee that every cut will be perfectly consistent in position and shape, resulting in a high defect rate. This makes it difficult to meet the demands of a market that values ​​high-quality, standardized production. While early traditional cutting equipment improved production efficiency to some extent, it revealed numerous problems in practical application. Traditional equipment lacked a material feeding function, requiring manual unloading after cutting, which affected the continuity and stability of production. Its low level of automation also contributed to low production efficiency. Summary of the Invention

The cutting and blanking mechanism is installed on the top of the mounting housing. An auxiliary cutting mechanism is provided directly below the cutting and blanking mechanism and is installed inside the mounting housing. The leather entering from the inlet is cut by the cutting and blanking mechanism under the support of the auxiliary cutting mechanism. The cut leather upper enters the cutting and blanking mechanism to wait for cutting. The feeding mechanism is installed inside the mounting housing and is located between the auxiliary cutting mechanism and the waste hopper. The feeding mechanism conveys the leather to be processed, allowing it to smoothly enter the cutting area. The cut leather is then conveyed to the waste hopper by the feeding mechanism. The cutting and unloading mechanism includes a cylinder, which is fixedly installed on the top of the mounting housing. A telescopic rod is fixedly connected to the telescopic end of the cylinder, which passes through the mounting housing and extends into it. A storage component is fixedly installed at the bottom of the telescopic rod. The storage component is used to store the cut leather uppers. A die cutter is fixedly installed at the bottom of the storage component. The die cutter is used to cut the leather and, in conjunction with the auxiliary cutting mechanism, cuts the leather into the required shape. A unloading component is installed on the side of the storage component. After cutting, the unloading component operates to unload the leather uppers from the storage component and drop them into the conveying mechanism, thus realizing the controllable unloading of the leather uppers from the storage component.

[0004] Preferably, the number of die cutters is four, and the four die cutters are evenly distributed at the bottom of the storage component. The storage component includes a lifting block, which is slidably mounted on the outer surface of the guide rail.

The lower die is pressed and matched with the die cutter. During cutting, the support plate is in a horizontal state, and the lower die is pressed and matched against the inner wall of the die cutter. The lower die presses the sliding rod to rotate. When material needs to be unloaded, the motor drives the rotating rod and the support plate to rotate, preventing the leather upper from accumulating on the auxiliary cutting mechanism and allowing it to fall smoothly onto the conveyor belt surface.

[0011] Preferably, the feeding mechanism includes a second motor, a first transmission shaft, and a second transmission shaft. The second motor is fixedly mounted on the top of the frame plate by a bracket. The first and second transmission shafts are rotatably mounted on the inner wall of the mounting housing.

[0013] This invention provides an automatic cutting device for leather shoe upper production. It has the following advantages: I. This automatic cutting device for leather shoe upper production, through the setting of the storage component, during cutting, the lifting block descends, the die cutter works, and the anti-leak plate rotates under the pressure of the leather and the lower die, allowing the leather to enter the storage tank. After cutting is completed, the lifting block rises, and the return spring resets the anti-leak plate to block the leather. The sliding rod slides in each groove, cooperating with the action of the anti-leak plate. During the cutting process, the anti-leak plate ensures that the leather can smoothly enter the storage tank and prevents the leather from falling off during the storage stage. This achieves effective temporary storage of the cut leather shoe upper, avoids the leather falling off when unnecessary, and ensures the orderly progress of the subsequent material feeding process.

[0014] II. This automatic cutting device for leather shoe upper production, through the setting of the unloading component, when unloading is required, cylinder two is activated, its telescopic end pushes telescopic rod two, telescopic rod two drives the top arc-shaped push block to move, the arc-shaped push block pushes the slide rod, causing the anti-leak plate to rotate around the pivot and open, the leather shoe upper in the storage tank is unobstructed and falls smoothly onto the conveying mechanism, realizing precise control of the unloading action of the leather shoe upper in the storage tank, ensuring the controllability and stability of the unloading process, and improving the production efficiency of leather shoe upper production.

[0015] III. This automatic cutting device for leather shoe upper production, through the setting of an auxiliary cutting mechanism, uses a motor to drive a rotating rod, a support plate, and a lower die to rotate. During cutting, the support plate is in a horizontal state, and the lower die cooperates with the die cutter to squeeze and cut the leather. During unloading, the motor drives the rotating rod to rotate the support plate and the lower die. The auxiliary cutting mechanism provides stable support for the leather during cutting to ensure cutting quality, and prevents the leather shoe upper from piling up on the auxiliary cutting mechanism during unloading, thereby improving the continuity of leather processing, reducing manual intervention, and lowering labor intensity.

[0016] IV. This automatic cutting device for leather shoe upper production, through the setting of the feeding mechanism, motor two drives gear two to rotate, which in turn drives gear one through gear meshing, thereby causing transmission shaft one and transmission shaft two to rotate synchronously, driving feeding roller one and feeding roller two to rotate to transport leather. During rotation, the large friction and squeezing action of the rubber material of feeding roller one and feeding roller two are used to clamp and transport the leather. The feeding mechanism reliably grips and transports the leather, avoiding slippage. The rubber material of the feeding rollers enables it to stably transport leather of different thicknesses and textures, improving the reliability of feeding, ensuring that the leather maintains the correct position during the transport process, and improving processing accuracy and product quality.

[0022] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 3 to 8As shown, the conveying mechanism 2 includes a motor 21 and a conveying shaft 22. The motor 21 is fixedly installed on the side of the frame 1 by a bracket. The conveying shaft 22 is rotatably installed at both ends of the frame 1.

During cutting, the support plate 73 is in a horizontal state, and the lower die 74 is pressed and adapted to the inner wall of the die cutter 45. The lower die 74 presses the sliding rod 436 to make it rotate. When it is necessary to unload the material, the motor 71 drives the rotating rod 72 and the support plate 73 to rotate, preventing the leather shoe upper from accumulating on the auxiliary cutting mechanism 7 and allowing it to fall smoothly onto the surface of the conveyor belt 24.

[0023] In use, the worker puts the leather to be processed into the mounting housing 3 through the feed port 8. The leather is placed between the first feed roller 54 and the second feed roller 55 of the feeding mechanism 5. The second motor 51 is started, and the second motor 51 drives the second transmission shaft 53 to rotate. The gears 57 at both ends of the second transmission shaft 53 rotate. Since the first gear 56 meshes with the second gear 57, the first transmission shaft 52 also rotates, which in turn drives the first feed roller 54 and the second feed roller 55 to rotate, conveying the leather towards the auxiliary cutting mechanism 7. When the leather is conveyed to the upper part of the auxiliary cutting mechanism 7, the cylinder 41 is activated. The telescopic end of the cylinder 41 drives the telescopic rod 42 to descend. The storage component 43 at the bottom of the telescopic rod 42 also descends. The die cutter 45 approaches the lower die 74. The lower die 74 squeezes the anti-leak plate 433 to make it rotate. The cut leather enters the storage tank 432. After the cutting is completed, the cylinder 41 drives the telescopic rod 42 to rise. The storage component 43 rises. Under the elastic force of the return spring 434, the anti-leak plate 433 returns to its original position, blocking the storage tank 432 to prevent the leather from falling out. When material needs to be unloaded, cylinder 441 is activated. The telescopic end of cylinder 441 drives telescopic rod 442 to extend. The arc-shaped push block 443 at the top of telescopic rod 442 pushes slide rod 436. Slide rod 436 slides inside slide groove 444, causing the anti-leakage plates 433 on both sides of storage tank 432 to open. The leather shoe upper in storage tank 432 falls onto the conveyor belt 24 of conveying mechanism 2. At the same time, motor 71 drives rotating rod 72 and support plate 73 to rotate, so that lower mold 74 is no longer in a horizontal state, preventing leather shoe upper from accumulating on auxiliary cutting mechanism 7. Leather waste generated during the cutting process falls into waste hopper 6 and is collected by waste hopper 6; Start motor 21, which drives conveyor shaft 22 to rotate. The conveyor roller 23 on the surface of conveyor shaft 22 rotates, which in turn drives conveyor belt 24 to transport the cut leather shoe upper to the designated position.
