Description

Technical Field

[0001] The utility model relates to the field of automobile leather cutting equipment, and more particularly to a laser leather cutting device. Background Art

[0002] Laser leather cutting equipment, as an advanced leather processing equipment, mainly uses a high-power density working laser beam to irradiate the surface of the leather material, causing it to quickly melt, vaporize or reach the ignition point, thereby completing the cutting process.

[0003] Existing laser leather cutting equipment usually lays the leather flat on the operating table when cutting leather. However, since the leather is stored by rolling before cutting, some leather will have a certain degree of curl if it has been stored for a long time when laid flat. The cut shape will also deviate from the expected size, resulting in different shapes of the final cut products. Utility Model Content

[0013] The technical effects and advantages of this utility model are:

[0014] 1. The utility model is provided with a fixing component and a reset component, and the two side edges of the leather to be cut and processed are clamped between the two clamping components respectively. The motor is started, and the reset component increases the distance between the two guide components. During processing, the distance between the two guide components is the same as the length of the leather to be processed.

Since the leather is in a suspended state, the laser beam of the laser cutting head melts the edge of the finished product. When the laser cutting head completes cutting, the finished product will directly fall from the square hole into the storage drawer for storage. After all the finished products are cut, the operator can also directly remove the leather waste by expanding the distance between the clamping columns. There is no need to remove the finished products one by one and then take away the waste, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Furthermore, the clamping assembly 502 includes two clamping columns 5021 and two movable rails 5022. The front and back sides of the clamping column 5021 at the top are fixedly connected to permanent magnets 5023, and the front and back sides of the clamping column 5021 at the bottom are fixedly connected to electromagnets 5025. The bottom of the permanent magnet 5023 is fixedly connected to a buffer spring 5024. A limiting groove with the same width as the permanent magnet 5023 is provided on the side of the movable rail 5022 close to the clamping column 5021.

[0027] Furthermore, the guide assembly 501 includes a guide column 5011, the front of the guide column 5011 is fixedly connected to the central axis 5014, the front and back sides of the outer side of the central axis 5014 are fixedly connected to the vertical mounting frame 5013, the bottom of the vertical mounting frame 5013 is fixedly connected to the top of the movable track 5022, and the front of the central axis 5014 is fixedly connected to the convex limit block 5012.

[0028] Furthermore, the storage assembly 1 includes an operating table 104, guide grooves 105 are opened on both sides of the inside of the operating table 104, the front of the operating table 104 is movably connected to the storage drawer 101, both sides of the storage drawer 101 are fixedly connected with guide strips 102, the front of the storage drawer 101 is fixedly connected with a handle 103, and a square hole 106 is opened on the top of the operating table 104.

[0029] Furthermore, one side of the return spring 702 is fixedly connected to a motor box 703, and the back of the take-up pulley 504 on one side is fixedly connected to a motor 505. The motor 505 is fixedly mounted on the inner side of the motor box 703, and a bearing is provided at the connection between the output shaft of the motor 505 and the motor box 703.

[0030] Specifically, the motor box 703 protects the motor 505 and is connected to both ends of the return spring 702 with the guide block 701 respectively. The motor box 703 is fixed in position and positions one side of the return spring 702.

[0031] Furthermore, the motor box 703 is fixedly connected to the front of the back mounting frame 3, the guide block 701 is fixedly connected to the take-up pulley 504 on the other side, and both sides of the crawler 503 are fixedly connected to the outer sides of the take-up pulleys 504 on both sides;

[0032] Specifically, when the starting motor 505 drives the take-up wheel 504 to rotate, if the track 503 is wound to the outside of the take-up wheel 504 on one side, the spring is in a compressed state. If the wound track 503 is released, the return spring 702 gradually extends, synchronously regulating the distance between the two guide components 501.

[0033] Furthermore, a movable groove is provided on the back of the sliding track 6, which is in the same shape and size as the outer side of the convex stop block 5012, and a bearing is provided at the connection between the central axis 5014 and the take-up pulley 504;

[0034] Specifically, during the movement of the guide assembly 501 , the convex limiting block 5012 moves along the sliding track 6 , and the sliding track 6 and the back mounting frame 3 jointly limit and support the fixing assembly 5 .

[0035] Furthermore, the size of the guide strip 102 is matched with the size of the guide groove 105, ensuring that the storage drawer 101 can be pulled out by pulling the handle 103 to take out the finished product. The width of the square hole 106 is the same as the length of the clamping column 5021, that is, the maximum clamping width of leather of the clamping column 5021 is adapted to the width of the square hole 106, ensuring that the finished leather within the range can fall through the square hole 106 after cutting.

[0036] The working principle of the present invention is as follows: when clamping leather, the motor 505 is first started to drive the take-up wheel 504 to rotate, and the track 503 is rolled up to the outside of the take-up wheel 504 on one side, that is, the guide assembly 501 on the other side is pulled to one side, shortening the distance between the two guide assemblies 501, such as Figure 3 As shown, the two sides of the leather are respectively inserted between the two clamping columns 5021 on both sides, and the clamping assembly 502 is energized to move the electromagnet 5025 upward, driving the clamping column 5021 at the bottom to move upward until one side of the leather is clamped. After clamping, the motor 505 is started to drive the take-up wheel 504 to rotate in the opposite direction, releasing the track 503 wound on the take-up wheel 504. Under the action of the return spring 702, the guide assembly 501 on the other side gradually moves away from the guide assembly 501 on one side until the distance between the two guide assemblies 501 is the same as the length of the leather. At this time, the leather is pulled into a straight state.

[0037] When the leather is in a straight state, the leather is suspended in the air, and the laser beam of the laser cutting head 4 melts the edge of the finished product. When the laser cutting head 4 completes cutting, the finished product will directly fall from the square hole 106 into the storage drawer 101 for storage. After all the finished products are cut, the remaining leather waste is energized by the clamping assembly 502 so that the electromagnet 5025 moves down to the initial state, releasing the clamping on both sides of the leather. The operator directly removes the leather waste and pulls out the storage drawer 101 by pulling the handle 103 to take out the finished product.

[0038] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
