Description

Technical Field

[0001] This utility model relates to the technical field of embossing devices, specifically a leather release paper composite embossing device. Background Technology

[0002] Leather release paper composite embossing equipment is a key piece of equipment in the leather processing industry. Its core function is to create specific textures or patterns on the leather surface through the combined effect of pressure and temperature, while simultaneously achieving composite processing with release paper. The equipment applies precise pressure (usually 5-20 MPa) through a hydraulic or pneumatic system, and uses an electric heating or hot oil circulation system to control the surface temperature of the embossing roller within the range of 120-200℃. The high temperature and high pressure conditions soften the leather surface fibers, and the texture (such as crocodile pattern or lychee pattern) on the surface of the embossing roller is embedded into the leather surface through mechanical extrusion, forming a permanent texture.

[0003] The existing technology for leather embossing has the following drawback: there is only one workstation. This means that the time spent on heat preservation after loading the material is wasted, and the workers can only wait for the embossing work to begin. Therefore, an improved leather release paper composite embossing device is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a leather release paper composite embossing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leather release paper composite embossing device, comprising a column, with embossing platforms fixedly installed on both sides of the upper end of the column. An extrusion mechanism for applying pressure is installed on the upper end of the embossing platform. The extrusion mechanism includes a slide rod, a slider, a top plate, a connecting rod, an extrusion plate, a hydraulic cylinder, a crossbar, and an electric push rod. Slide rods are fixedly installed on both sides of the upper end of the embossing platform. Sliders are movably sleeved on the outer surface of the slide rods. A top plate is fixedly installed between the sliders. Connecting rods are movably inserted at the four corners of the outer surface of the top plate. An extrusion plate is fixedly installed at the lower end of the connecting rod. A hydraulic cylinder is fixedly installed in the middle of the inner side of the top plate. A crossbar is fixedly installed between the slide rods. An electric push rod is fixedly installed on the surface of the crossbar.

[0006] Preferably, the movable end of the electric push rod is fixedly connected to the top plate. The extension and retraction of the electric push rod can drive the top plate and the extrusion plate to move and adjust on the two embossing platforms. When the electric push rod is fully retracted, it can drive the extrusion plate to align with one embossing platform, and when the electric push rod is fully extended, it can drive the extrusion plate to align with the other embossing platform.

[0007] Preferably, a baffle is fixedly provided at the lower end of the slider surface. When the extrusion plate of this device is performing embossing work, the baffle can isolate the extrusion area. That is to say, when the worker is working, when picking up and placing leather, he should stand in the direction of the baffle. When the extrusion plate is at the upper end of a work station for embossing work, the baffle just isolates the extrusion area to prevent the worker from placing his hand on the upper end of the embossing platform, thereby ensuring the working safety of the device.

[0008] Preferably, a force-bearing plate is fixedly installed on both sides of the baffle surface, and a pressure sensor is fixedly installed between the force-bearing plate and the baffle. When something obstructs the left and right movement of the baffle and the top plate, the pressure sensor can detect it. Then the pressure sensor can be linked with the control box to stop the electric push rod from working, so as to prevent the baffle from squeezing the staff.

[0009] Preferably, the movable end of the hydraulic cylinder is fixedly connected to the extrusion plate. The contraction of the hydraulic cylinder can drive the extrusion plate to move up and down, thereby enabling the extrusion printing of leather.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model is equipped with a dual workstation. While the embossing work is being carried out at one workstation, the other workstation is used for loading and unloading. This makes full use of the embossing time, thereby greatly improving the embossing efficiency of this device.

[0012] 2. This utility model uses a baffle to isolate the extrusion area. That is to say, when workers are working, they should stand in the direction of the baffle when picking up and placing leather. When the extrusion plate is at the top of a work station for embossing, the baffle isolates the extrusion area to prevent workers from placing their hands on the top of the embossing platform, thereby ensuring the safety of the device.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a leather release paper composite embossing device, including a column 1, with embossing platforms 2 fixedly installed on both sides of the upper end of the column 1. An extrusion mechanism for applying pressure is installed on the upper end of the embossing platform 2. The extrusion mechanism includes a slide rod 3, a slider 4, a top plate 5, a connecting rod 6, an extrusion plate 7, a hydraulic cylinder 8, a crossbar 9, and an electric push rod 10. Slide rods 3 are fixedly installed on both sides of the upper end of the embossing platform 2. Slide rods 4 are movably sleeved on the outer surface of the slide rods 3. A top plate 5 is fixedly installed between the sliders 4. Connecting rods 6 are movably inserted at the four corners of the outer surface of the top plate 5. An extrusion plate 7 is fixedly installed at the lower end of the connecting rod 6. A hydraulic cylinder 8 is fixedly installed in the middle of the inner side of the top plate 5. A crossbar 9 is fixedly installed between the slide rods 3. An electric push rod 10 is fixedly installed on the surface of the crossbar 9.

[0019] The movable end of the electric push rod 10 is fixedly connected to the top plate 5. The extension and retraction of the electric push rod 10 can drive the top plate 5 and the pressing plate 7 to move and adjust on the two embossing platforms 2. When the electric push rod 10 is fully retracted, it can drive the pressing plate 7 to align with one embossing platform 2. When the electric push rod 10 is fully extended, it can drive the pressing plate 7 to align with the other embossing platform 2.

[0020] A baffle 11 is fixedly provided at the lower end of the surface of the slider 4. When the extrusion plate 7 of this device is performing embossing work, the baffle 11 can isolate the extrusion area. That is to say, when the worker is working, when picking up and placing leather, he should stand in the direction of the baffle 11. When the extrusion plate 7 is at the upper end of a work station to perform embossing work, the baffle 11 just isolates the extrusion area to prevent the worker from putting his hand on the upper end of the embossing platform 2, thereby ensuring the working safety of the device.

[0021] Force plates 12 are fixedly installed on both sides of the surface of the baffle 11. A pressure sensor 13 is fixedly installed between the force plate 12 and the baffle 11. When something obstructs the left and right movement of the baffle 11 and the top plate 5, the pressure sensor 13 can detect it. Then the pressure sensor 13 can be linked with the control box to control the electric push rod 10 to stop working, so as to prevent the baffle 11 from squeezing the staff.

[0022] The movable end of the hydraulic cylinder 8 is fixedly connected to the extrusion plate 7. The retraction of the hydraulic cylinder 8 can drive the extrusion plate 7 to move up and down, thereby enabling the extrusion printing of leather.

[0023] Working principle: This device has two embossing platforms 2. Initially, the operator lays the leather to be embossed on one embossing platform 2. Then, the hydraulic cylinder 8 extends and pushes the extrusion plate 7 downward to emboss the leather. While the operator is embossing, the operator can lay the leather to be embossed on the other embossing platform 2. In this way, the operator can load materials during the embossing time. After one side is embossed, the hydraulic cylinder 8 retracts and moves the extrusion plate 7 upward. Then, the electric push rod 10 extends to switch the position of the extrusion plate 7. This dual-station setup allows for loading and unloading of materials while embossing is being done at one station. By utilizing the embossing time, the embossing efficiency of this device can be greatly improved.

[0024] Furthermore, when using this device, the baffle 11 can isolate the squeezing area. In other words, when workers are working, they should stand in the direction of the baffle 11 when picking up and placing leather. When the squeezing plate 7 is at the top of a work station for embossing, the baffle 11 will isolate the squeezing area to prevent workers from placing their hands on the embossing platform 2, thereby ensuring the safety of the device.
