[0002] In the manufacturing process of leather products, leather cutting is a crucial step. It not only determines the final shape of the product, but also directly affects its quality and production efficiency. With the rapid development of industrial automation, traditional manual cutting methods are gradually being replaced by modern automatic cutting equipment due to their low efficiency, poor precision, and high labor intensity. Among them, hydraulic cutting machines have been widely used in the leather processing industry due to their powerful power output, high-precision cutting capabilities, and stable performance. Hydraulic cutting machines use hydraulic systems to drive blades for high-speed and precise cutting, which can effectively improve cutting efficiency and ensure the smoothness and consistency of the cut edges.

[0031] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0032] As described in the background technology, when the hydraulic shearing machine is working, the blade seat bears huge pressure and impact force, and it is necessary to ensure that it can remain stable under any circumstances. However, in the non-working state or during maintenance, if there is a lack of effective support and limiting measures, the blade seat may accidentally fall due to external forces (such as misoperation, hydraulic system failure, etc.). This situation will not only cause damage to the equipment, but may also cause serious safety accidents and cause personal injury to the operator.
[0033] In order to solve this technical problem, the utility model provides a leather cutting device, which is used for cutting leather.
[0034] Specifically, please refer to Figure 1-Figure 2 , the leather cutting device specifically includes:
[0035] The machine base 1 has support bases 2 fixedly installed on both sides of the top of the machine base 1, and a cutting mechanism is arranged between the two support bases 2. The cutting mechanism includes a knife seat 302 arranged between the two support bases 2, and a cutting knife 303 is installed at the bottom of the knife seat 302; grooves are provided on the sides of the two support bases 2 that are close to each other, and support blocks 4 are movably arranged in the two grooves.
[0036] The leather cutting device provided by the present invention provides a support block 4, which can be moved to the bottom of the knife holder 302 after the knife holder 302 is raised to support the knife holder 302. By means of physical blocking, the risk of the knife holder 302 falling accidentally is fundamentally eliminated, providing a safer working environment for the operator and reducing the incidence of production accidents.
[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.
[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0040] Example 1, please refer to Figure 1-Figure 2, a leather cutting device includes a machine base 1, support seats 2 are fixedly installed on both sides of the top of the machine base 1, a cutting mechanism is arranged between the two support seats 2, the cutting mechanism includes a knife seat 302 arranged between the two support seats 2, and a cutting knife 303 is installed at the bottom of the knife seat 302; the two support seats 2 are provided with grooves on the sides close to each other, and support blocks 4 are movably arranged in the two grooves; the support block 4 set in this application can be moved to the bottom of the knife seat 302 after the knife seat 302 is raised to support the knife seat 302, and the risk of accidental falling of the knife seat 302 is fundamentally eliminated by physical blocking, providing a safer working environment for operators and reducing the incidence of production accidents.
[0041] Further, such as Figure 1-Figure 2 As shown, a second hydraulic cylinder 401 is installed on the side of the two support seats 2 that are away from each other. The piston rod of the second hydraulic cylinder 401 passes through the support seat 2 and is fixedly connected to the support block 4. The second hydraulic cylinder 401 can drive the support block 4 to move to adjust the position of the support block 4.
[0042] Further, such as Figure 1 As shown, detection switches 402 are embedded in both grooves, and the detection switches 402 are connected to the hydraulic system of the first hydraulic cylinder 301 so that the first hydraulic cylinder 301 is operated after the detection switches 402 are touched by the support block 4.
[0043] Further, such as Figure 1-Figure 2 As shown, a slide groove 304 is provided on the side wall of the support seat 2, and a slider 305 is slidably connected in the slide groove 304. The side of the slider 305 is fixedly connected to the knife seat 302. The slide groove 304 and the slider 305 cooperate with each other to limit the knife seat 302, making the knife seat 302 more stable when lifting and lowering, ensuring the stability of the knife seat 302 lifting and lowering, and improving the cutting quality. The knife seat 302 needs to be lifted and lowered frequently during the cutting operation, and the cooperation of the slide groove 304 and the slider 305 provides precise guidance and limitation for the lifting and lowering of the knife seat 302, avoiding the knife seat 302 from shaking left and right or tilting during the lifting process. This stable lifting movement helps the cutting knife 303 to maintain constant pressure and angle during the cutting process, thereby improving the cutting quality.
[0044] Further, such as Figure 1-Figure 2 As shown, a connecting beam 3 is fixedly connected between the two support seats 2, and a first hydraulic cylinder 301 is fixedly installed on the connecting beam 3. The bottom end of the first hydraulic cylinder 301 is connected to the tool holder 302. The connecting beam 3 can support the first hydraulic cylinder 301, and the first hydraulic cylinder 301 can drive the tool holder 302 to move up and down.
[0045] Example 2 further optimizes the leather cutting device provided in Example 1. Specifically, Figure 1-Figure 5 As shown, two support arms 5 are fixedly installed on one side of the machine base 1, and a first support plate 503 is provided between the two support arms 5 and the top of the machine base 1 to provide a support platform for the leather material to facilitate cutting operations.
[0046] Further, such as Figure 4-Figure 5 As shown, guide rails 501 are installed between the two support arms 5 and the top of the machine base 1, and the outer surface of the guide rails 501 is slidably connected to the slide 502, and the slide 502 is fixedly connected to the bottom of the first support plate 503. The slide 502 and the guide rails 501 cooperate with each other to limit the first support plate 503, which can improve the stability of the movement of the first support plate 503 and ensure the cutting accuracy. The cooperation between the guide rails 501 and the slide 502 provides precise guidance and limitation for the movement of the first support plate 503, so that the first support plate 503 will not shake left and right or deviate from the track during the movement. This stable movement method helps to maintain the position accuracy of the leather during the cutting process and ensure the accuracy of cutting.
[0047] Further, such as Figure 3 As shown, a pad 504 is installed on the top of the first support plate 503 by bolts. The pad 504 can reduce the damage caused by the cutting knife 303 to the pad 504, and also reduce the damage caused by the pad 504 to the cutting knife 303. The pad 504 is made of resin. The pad 504 made of resin has certain elasticity and wear resistance, and can play a buffering role in the cutting process, reducing the direct collision and wear between the cutting knife 303 and the pad 504.
[0048] Further, such as Figure 4 As shown, a second support plate 505 is fixedly mounted on the bottom of the first support plate 503 , and the second support plate 505 is slidably connected to the top of the base 1 , so that the second support plate 505 can support the bottom of the first support plate 503 .
[0049] Example 3 further optimizes the leather cutting device provided in Example 1 or 2. Specifically, Figure 1-Figure 5As shown, a limiting seat 509 is fixedly installed on the front of the machine base 1, and a limiting groove 510 is provided on the limiting seat 509. A connecting port 506 is provided on the first support plate 503. A limiting plate 507 is connected between the connecting port 506 and the limiting groove 510. A handle 508 is fixedly connected to the top of the limiting plate 507. The plugging of the limiting plate 507 and the limiting groove 510 can limit the first support plate 503, thereby improving the stability of the first support plate 503 during the cutting process and preventing the first support plate 503 from accidentally moving or shaking during the cutting process. This stable structure helps to maintain the position accuracy of the leather material during the cutting process and ensure the accuracy of the cutting. At the same time, the provision of the handle 508 facilitates the operator's insertion and removal of the limiting plate 507, thereby improving the convenience of use of the device.
[0050] The use process of the leather cutting device provided by the utility model is as follows:
[0051] Pull the handle 508 upward to separate the limit plate 507 from the limit groove 510, pull the first support plate 503 to move the first support plate 503 away from the cutting knife 303, place the leather material to be cut on the pad 504, and adjust the position of the leather material so that the leather cutting position corresponds to the cutting knife 303 when the pad 504 is pushed back to its original position. After the pad 504 is pushed back to its original position, insert the limit plate 507 into the limit groove 510 to limit the position of the first support plate 503, and then the second hydraulic cylinder 401 drives the support plate 507 to move away from the cutting knife 303. Block 4 is away from the pad 504, so that the support block 4 is moved away from the bottom of the knife holder 302. When the support block 4 touches the detection switch 402, it means that the support seat 2 is in contact with the support limit of the knife holder 302. At this time, the first hydraulic cylinder 301 is allowed to operate. The first hydraulic cylinder 301 drives the knife holder 302 to descend so that the cutting knife 303 cuts the leather. After cutting is completed, the first hydraulic cylinder 301 drives the knife holder 302 to rise, and then the second hydraulic cylinder 401 pushes the support block 4 to move to the bottom of the knife holder 302 to support the knife holder 302.
