Description

Technical Field

[0001] The invention belongs to the technical field of leather processing, and in particular relates to a leather cutting machine device used for the production of leather goods and bags. Background Art

[0002] In the fiercely competitive leather goods and luggage market, product diversity, individuality and high quality are the key to a company's survival. Traditional leather processing methods such as manual cutting and die stamping have problems such as low precision, poor efficiency and lack of flexibility, which make it difficult to meet production needs.

[0003] The emergence of laser cutting technology has brought changes to the production of leather goods and bags. Leather laser cutting machines use high-energy-density laser beams to instantly melt or vaporize leather to achieve precise cutting. It has high precision, can cut complex patterns and fine parts, and has high speed, which can improve production efficiency. Non-contact processing avoids mechanical damage to the leather surface and improves product quality. At present, laser cutting machines are mainly composed of a laser, a motion system for controlling the movement of the laser, and a carrying platform for carrying the leather to be processed. Among them, some of the leathers used in the production of leather goods and bags are small original leathers, large original leathers, and some are artificial leathers. Depending on the type of leather to be processed, the carrying platform can be divided into fixed and non-fixed types.

[0004] For example, during the operation of the fixed platform disclosed in the patent document with publication number CN 219010338 U, the loading and unloading of leather must be done manually, which limits the operation efficiency to a certain extent. However, due to its excellent support stability, it can achieve high precision when cutting leather, and is particularly suitable for cutting high-quality raw materials.

[0005] For example, the non-fixed load platform disclosed in the patent document with publication number CN 218345480 U is usually achieved with the help of a belt conveyor, which can realize the automatic loading and unloading function, thereby meeting the needs of continuous operation. However, the carrying capacity of the belt conveyor is limited. When processing heavy leather, the surface of the belt conveyor is prone to sinking, making it difficult to maintain a flat state on the leather surface, which ultimately affects the cutting accuracy. Therefore, this type is more suitable for mass production scenarios.

[0006] Since the above-mentioned laser cutting machine equipment has a single usage scenario and cannot take both efficiency and stability into account, we propose a leather cutting machine equipment for leather goods and bags production to solve the above problems. Summary of the invention

[0010] Preferably, the movable plates are in a group, and fixed plates are respectively provided on both sides of the movable plates, and the fixed plates are fixedly mounted on the machine body. When the movable plates are in a first state, they form a complete plane with the fixed plates; when the movable plates are in a second state, the fixed plates are used to support the movable plates.

[0011] Preferably, the guide roller assembly includes a fixed frame and a guide roller sleeve rotatably mounted on the fixed frame, and a first lifting unit is installed on the control module.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] like Figure 1 - Figure 8 As shown, a leather cutting machine device for leather goods and bags production includes a body 1 and a laser head 2, wherein the laser head 2 uses a carbon dioxide laser. A driving component 3 is installed on the body 1, and its function is to drive the laser head 2 to move precisely. The driving component 3 includes a transverse driving mechanism and a longitudinal driving mechanism, and these two mechanisms work together to drive the laser head 2 to any specified position, thereby meeting the needs of processing at different positions during the leather cutting process.

[0032] A load-bearing platform is provided below the laser head 2 for carrying the leather to be cut. In the prior art system, the load-bearing platform is mainly divided into two types: fixed and non-fixed. During the operation of the fixed platform, the loading and unloading of the leather must be done manually, which limits the operating efficiency to a certain extent. However, due to its excellent support stability, it can achieve higher precision when cutting the leather, which is particularly suitable for cutting and processing high-quality raw materials (such as fine original leather). The non-fixed load-bearing platform is usually achieved with the aid of a belt conveyor, which can realize the automatic loading and unloading function, thereby meeting the needs of continuous operation, and is particularly suitable for artificial leather. However, the carrying capacity of the belt conveyor is limited. When handling heavy original leather, the surface of the belt conveyor is prone to sinking, which makes it difficult to maintain a flat state on the leather surface, which ultimately affects the cutting accuracy. Therefore, this type is more suitable for mass production scenarios.

[0033] In the present application, the carrier includes at least one movable plate 4. The movable plate 4 can be raised, lowered and rotated relative to the machine body 1. When the movable plate 4 is in the first state, its lower end contacts the machine body 1 to form a stable support structure, providing convenient conditions for high-precision cutting of leather. When the movable plate 4 is in the second state, a gap is formed between the front and rear sides of the movable plate 4 and the machine body 1 for the leather to pass through, and the gap allows the leather to be continuously fed, and the part of the leather to be cut can be placed on the movable plate 4 to achieve stable support.

[0034] A control module 5 is arranged below the movable plate 4. The control module 5 has the function of controlling the movable plate 4 to switch between the first state and the second state, that is, controlling the movable plate 4 to realize lifting and rotating actions. No less than two sets of guide roller assemblies 7 are installed on the control module 5. When the movable plate 4 is in the first state, the guide roller assembly 7 is located below the movable plate 4, and the movable plate 4 can shield the guide roller assembly 7, thereby forming a fixed working platform. When the movable plate 4 is in the second state, the guide roller assembly 7 is respectively located at the front and rear sides of the movable plate 4, which can play a guiding role for the continuously transported leather, so that the movable plate 4 and the guide roller assembly 7 together constitute a continuous working platform.

[0035] In this embodiment, the number of movable panels 4 is one group, and a fixed plate 41 is provided on each side of the movable panel 4, and the fixed plate 41 is fixedly mounted on the machine body 1. When the movable panel 4 is in the first state, it and the fixed plates 41 on both sides together form a complete plane. Specifically, a certain space is reserved between the two fixed plates 41, and the movable panel 4 is located in the space, and in the first state, the movable panel 4 is flush with the surfaces of the two fixed plates 41, so that the fixed plates 41 and the movable panel 4 together form a complete fixed plane for placing leather. When the movable panel 4 is in the second state, the movable panel 4 rises from the initial position and rotates 90 degrees, so that its two ends are respectively placed on the upper ends of the two fixed plates 41, and at this time, the fixed plates 41 play a supporting role for the movable panel 4. In summary, whether the movable panel 4 is in the first state or the second state, it is directly or indirectly connected to the machine body 1 and forms a stable supporting structure.

[0036] The guide roller assembly 7 is composed of a fixed frame 71 and a guide roller sleeve 73 rotatably mounted on the fixed frame 71. The fixed frame 71 includes a fixed shaft and a connecting frame connecting the two ends of the fixed shaft, and the guide roller sleeve 73 is rotatably mounted on the outside of the fixed shaft. The rotation design of the guide roller sleeve 73 can transform the contact form of the leather into rolling friction, thereby reducing resistance. The control module 5 is equipped with a first lifting unit 72, which is connected to the fixed frame 71 and is used to regulate the lifting and lowering of the guide roller assembly 7. Specifically, the first lifting unit 72 can be selected from one or more combinations of electric cylinders, air cylinders, and hydraulic cylinders, and its output end is connected to the fixed frame 71 to achieve the lifting function. The purpose of setting the first lifting unit 72 is to control the height of the guide roller assembly 7: during the leather conveying process, the height of the guide roller assembly 7 is set to be higher than the movable plate 4, thereby further reducing the friction between the leather and the movable plate 4; during the leather cutting process, the height of the guide roller assembly 7 is set to be lower than the movable plate 4, so that the leather is completely placed on the upper end of the movable plate 4 to play a supporting role.

[0037] It should be clear that an opening should be reserved on one side of the machine body 1 for leather to enter the interior of the machine body 1. At the same time, a winding roller for winding waste leather is installed on the other side of the machine body 1 to provide power support for the continuous transportation of leather.

[0038] Therefore, when the movable plate 4 is in the second state, the guide roller assembly 7 with lifting function can not only guide the leather and reduce its friction, but also adjust the contact state between the leather and the movable plate 4, reduce the resistance during the transportation of the leather, and make it more stable during the cutting process. In addition, the two ends of the guide roller sleeve 73 are respectively provided with limited stoppers 74 to prevent the leather from deviating during the transportation process. The stoppers 74 are fixedly mounted on the fixed frame 71 and can be raised and lowered synchronously with the guide roller assembly 7.

[0039] The upper part of the stopper 74 is set as an arc surface, and the lower surface of the movable plate 4 is correspondingly provided with an arc-shaped docking groove 44. When the movable plate 4 is in the first state, the guide roller assembly 7 can directly move upward, and with the help of the synergistic effect of the stopper 74 and the docking groove 44, force is directly applied to the bottom of the movable plate 4 to push it upward. This design facilitates the disassembly and installation of the movable plate 4 and is conducive to maintenance operations.

[0040] In addition, when cleaning the movable plate 4 , the two guide roller assemblies 7 can be controlled to rise to different heights respectively, so that the movable plate 4 is tilted, thereby facilitating the removal of debris or dust attached to the surface of the movable plate 4 .

[0041] A fixing base 6 is provided below the control module 5, and the fixing base 6 is firmly mounted on the machine body 1. A second lifting unit 61 for adjusting the height of the control module 5 is mounted on the fixing base 6. The second lifting unit 61 can be one or more combinations of electric cylinders, air cylinders, and hydraulic cylinders, and its output end is connected to the control module 5 to realize the lifting function.

[0042] The control module 5 is equipped with a support platform 51 at the upper end for providing support for the movable plate 4. A driving unit is installed inside the support platform 51, and its function is to drive the movable plate 4 to rotate horizontally. The driving unit can be driven directly or indirectly by a motor or other driving source. In the present embodiment, the driving unit includes a driving shaft 52 installed in the support platform 51, and the driving shaft 52 is connected to the driving source. In the present embodiment, the driving shaft 52 can be connected to the servo motor through a transmission mechanism, so that the driving shaft 52 can accurately rotate 90 degrees in the clockwise or counterclockwise direction each time. The driving shaft 52 is vertically arranged, and its upper end is detachably connected to the movable plate 4 to facilitate the disassembly operation of the movable plate 4.

[0043] The upper end of the driving shaft 52 is fixedly connected to the driving disk 53, and a plurality of plug-in slots 54 are provided on the driving disk 53. A plurality of plug-in rods 43 matching the plug-in slots 54 are fixedly installed on the lower end of the movable plate 4. When the plug-in rods 43 are inserted into the plug-in slots 54, the power transmission connection between the driving disk 53 and the movable plate 4 can be realized.

[0044] The lower end of the movable plate 4 is connected to a fixing ring 42, and the plug rod 43 is connected to the fixing ring 42. The fixing ring 42 and the support platform 51 are adapted to each other. Specifically, the support platform 51 is provided with a circular groove adapted to the fixing ring 42. The setting of the fixing ring 42 can effectively enhance the connection strength between the plug rod 43 and the movable plate 4.

[0045] The working principle is as follows: when finishing a large piece of high-quality leather, the movable plate 4 is adjusted to be flush with the fixed plate 41, and the cutting operation is performed by laser. When continuous operation and batch processing are required, the second lifting unit 61 is first started to lift the control module 5 upward until the movable plate 4 is higher than the fixed plate 41; then, by controlling the rotation of the drive shaft 52, the movable plate 4 is rotated 90 degrees to expose the gap between the movable plate 4 and the machine body 1; then, the second lifting unit 61 is lowered until the lower end of the movable plate 4 contacts the upper end of the fixed plate 41, and the fixed plate 41 provides support for the movable plate 4. After that, the rolled leather is fed in from one end of the movable plate 4 and sent out from the other end, so as to realize continuous processing of the leather.

[0046] In addition, it should be particularly pointed out that the present application precisely controls the movement of the first lifting unit 72 and the coiling shaft by controlling the circuit board. When the first lifting unit 72 rises to a position above the movable plate 4, the coiling shaft starts to coil the material; when the first lifting unit 72 drops to a position flush with or below the movable plate 4, the coiling shaft stops coiling the material. In this way, it can be ensured that the leather minimizes contact with the movable plate 4 during transportation, thereby reducing resistance; and when cutting, the leather can be completely in contact with the movable plate 4, thereby enhancing the support effect. In summary, the present application combines the advantages of both the existing fixed and non-fixed load-bearing platforms, and can effectively improve the cutting quality while ensuring processing efficiency. At the same time, the structural design of the present application is compact, occupies less space, and is conducive to carrying out miniaturized production and processing operations.

[0047] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
