[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 This utility model provides an implementation scheme: In the modern leather cutting process, laser or vibrating cutting blades are often used to cut the leather. During the cutting process, the material is cut by the horizontal movement of the cutting blade. However, leather cutting machines often require manual pulling. This pulling method also requires leveling, which is not only laborious to operate, but also easy to cause wrinkles and damage to the cut leather.
[0020] To address the aforementioned issues, this application discloses a leather cutting machine. A cutting machine frame 1 serves as the main support for the equipment. The cutting machine frame 1 is a rectangular frame structure. Leather is placed on the cutting machine frame 1 for cutting. A pair of parallel moving rails 2 are provided on the cutting machine frame 1. A sliding truss 3 is mounted on the pair of moving rails 2. The sliding truss 3 can move horizontally in the X direction on the pair of moving rails 2. A linear control motor 4 is mounted on the sliding truss 3, and a laser cutting blade 5 is mounted on the sliding truss 3. The laser cutting blade 5 is connected to the moving end of the linear control motor 4. Thus, the linear control motor 4 can move the laser cutting blade 5 and adjust its position in the horizontal Y direction. The two work together to allow the laser cutting blade 5 to move omnidirectionally within a horizontal range, thereby achieving the cutting of irregularly shaped leather. It should be noted that although this application discloses a laser cutting blade 5, its cutting method is not limited to laser cutting and can be replaced with other cutting tools.
[0021] Furthermore, a support roller frame 6 is provided on one side of the feeding frame 1, and a material stepping controller 7 is provided on the feeding frame 1. The material roll is placed through the support roller frame 6, and the material stepping controller 7 on the feeding frame 1 can control the roll to step out the material, which is convenient for processing and avoids the problem of material wrinkles caused when manually pulling the material.
[0022] Specifically, the aforementioned material stepping controller 7 includes a stepping motor 71, which serves as the power mechanism of the equipment. A gear set 72 is connected to the drive end of the stepping motor 71, and a pair of opposing extrusion rollers 73 are connected to the gear set 72. The drive end of the stepping motor 71 drives the gear set 72 to rotate, and the movement of the gear set 72 drives the pair of extrusion rollers 73 to rotate relative to each other, thereby conveying the material passing between them. According to the controller settings, after cutting, the stepping motor 71 rotates a certain number of times according to the set parameters, thereby driving the pair of extrusion rollers 73 to push the leather out in one direction through the pushing action of the gear set 72.
[0023] Furthermore, according to the instruction manual appendix Figure 1-3 It can be seen that the above-mentioned material stepping controller 7 also includes a pushing device 74, which is arranged on the unloading frame 1. The pushing device 74 is located on one side of the extrusion roller 73. A power assembly 75 is provided on the pushing device 74, and the power assembly 75 is connected to the gear set 72.
[0024] In the specific implementation process, the pushing device 74 plays the role of extending and conveying the leather. The pushing device 74 is located on one side of the extrusion roller 73. The pushing device 74 is used for conveying the leather on one hand and is a platform for leather cutting and processing on the other hand. It is linked with the gear set 72 through the power component 75. In this way, when the gear set 72 drives the extrusion roller 73 to move, it can drive the pushing device 74 to move synchronously, thereby enhancing synchronization and reducing energy consumption.
[0025] As a preferred option, a pair of moving tracks 2 are symmetrically arranged on the unloading frame 1, and a pair of sliding seats are provided on both sides of the sliding truss 3 to match the pair of moving tracks 2. The pair of moving tracks 2 serve to limit the movement of the pair of sliding seats.
[0026] As a preferred option, further according to the appendix to the instruction manual... Figure 1-3 It is known that the above-mentioned pushing device 74 includes at least a pair of flat rollers 741, a pair of flat rollers 741 are mounted on the unloading frame 1, and an operating roller belt 742 is sleeved on the pair of flat rollers 741.
[0027] In the specific implementation process, a pair of flat roller shafts 741 are symmetrically arranged to support the operating roller belt 742. The pair of flat roller shafts 741 drive the operating roller belt 742 for belt drive. After the leather passes between a pair of extrusion push rollers 73, it is laid flat on the operating roller belt 742. Then, the operating roller belt 742 drives the flat leather through the laser cutting knife 5, which plays the role of feeding and supporting.
[0028] As a preferred embodiment, the aforementioned power assembly 75 further includes a pair of propulsion sprockets 751. A pair of propulsion sprockets 751 are provided at the ends of a pair of flattening roller shafts 741. A propulsion chain 752 is sleeved on the pair of propulsion sprockets 751. The pair of propulsion sprockets 751 and the propulsion chain 752 constitute a sprocket system. One of the propulsion sprockets 751 is driven to rotate by the gear set 72. In turn, under the transmission action of the propulsion chain 752, the propulsion sprocket 751 drives the flattening roller shaft 741 to rotate, thereby achieving the purpose of driving material transport.
[0029] As a preferred option, further according to the appendix to the instruction manual... Figure 1-3 It is known that the gear set 72 includes a pair of counter-rotating gears 721, which are connected to a pair of extrusion rollers 73. The pair of counter-rotating gears 721 mesh with each other. A power sprocket 722 is coaxially arranged on one side of one of the counter-rotating gears 721, and a transmission sprocket 723 is coaxially arranged on one of the push sprockets 751. The transmission sprocket 723 and the power sprocket 722 are linked by a chain.
[0030] In the specific implementation process, the stepper motor 71 drives one of the counter-rotating gears 721 in a pair to rotate, thereby causing the counter-rotating gears 721 to mesh and rotate relative to each other. Since the pair of counter-rotating gears 721 are connected to a pair of extrusion rollers 73, the pair of counter-rotating gears 721 are driven. At the same time, since the power sprocket 722 is connected to the counter-rotating gears 721, the power sprocket 722 rotates synchronously with the counter-rotating gears 721. Then, through the chain linkage between the power sprocket 722 and the transmission sprocket 723, the transmission sprocket 723 drives the push sprocket to rotate, thereby realizing power transmission.
[0031] In summary, this leather cutting machine uses a horizontally moving truss to support the cutting blade, enabling continuous horizontal movement. The cutting blade cuts the leather into pieces. The gear set 72, controlled by a stepper motor 71, synchronously drives the conveying device and the extrusion roller 73. Thus, the leather is automatically fed under the pushing action of the extrusion roller 73 and the support of the conveying device. The structure is simple, it can convey materials step by step, and it does not require manual traction. During the process, the leather moves forward in parallel without adjustment, avoiding wrinkles.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
