Description

Technical Field

[0001] This utility model relates to the technical field of leather carving embossing tools, and in particular to a leather carving embossing tool with replaceable pattern modules. Background Technology

[0002] Leather embossing machines are specialized tools used to imprint patterns on the surface of leather. They transfer patterns from a metal mold to moist leather through physical pressure and are the core equipment in the surface embossing process.

[0003] An embossing tool uses pressure to imprint a pattern from a metal mold onto the leather surface, achieving a decorative finish. The leather must first be evenly moistened to soften it and better accept the embossing. Then, the metal mold is placed in the target location, and pressure is applied using the embossing tool to transfer the pattern. This process requires precise control of temperature, pressure, and mold position to ensure the integrity and clarity of the pattern.

[0004] However, existing embossing machines cannot adjust the pressure applied during embossing on leather surfaces, and leather varies in thickness, hardness, and texture. If the embossing machine has a fixed pressure, insufficient pressure may result in unclear patterns when embossing thicker or harder leathers. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing embossing machines cannot adjust the pressure when embossing leather surfaces, even though leather thickness, hardness, and texture vary. If the embossing machine pressure is fixed, insufficient pressure may result in unclear patterns when embossing thicker or harder leathers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leather carving embossing device with replaceable pattern modules, comprising a base, an upper end of which is provided with a lifting embossing adjustment component, the lifting embossing adjustment component comprising a fixed frame, sliding frames connected to the four bottom corners of the fixed frame, a servo motor connected to the top center of the fixed frame, a threaded rod connected to the output end of the servo motor, a threaded post connected to the surface of the threaded rod, a threaded hole opened inside the threaded post, a pressure sensor connected to the bottom of the threaded post, a lifting frame connected to the bottom of the pressure sensor, sliders connected to the four corners of the lifting frame, a PLC controller connected to one outer surface of the fixed frame, and a module assembly connected to the bottom of the lifting frame.

[0007] Furthermore, the PLC controller is electrically connected to an external power supply via a control switch. The PLC controller is electrically connected to the pressure sensor and the servo motor.

[0008] Furthermore, the output end of the servo motor is fixedly connected to the threaded rod, and the threaded rod is threadedly connected to the threaded post through the threaded hole.

[0009] Furthermore, the size of the four sets of sliders matches the size of the four sets of sliding frames, and the sliders and sliding frames form a sliding connection.

[0010] Furthermore, the bottom surface of the base is provided with a disassembly assembly, which includes a groove, and the lifting frame is connected to a sleeve at each of the four top corners near the groove.

[0011] Furthermore, a hand-tightening bolt is inserted into the inside of the sleeve, and a fixing block is fixedly connected to the surface of the hand-tightening bolt.

[0012] Furthermore, each of the module components has a threaded groove at the position where it matches the four sets of hand-tightening bolts.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when performing embossing on leather, the embossing pressure can be adjusted according to the current thickness of the leather. Then, the PLC controller will operate the servo motor to start, so that the module component can move downward automatically to realize the embossing operation on the leather. When the pressure reaches the required squeezing, the servo motor will automatically stop moving, so that the module component can no longer move downward automatically, thus protecting the leather. This avoids the problem that traditional embossing machines cannot adjust the pressure during embossing, which may lead to unclear pattern imprinting due to insufficient pressure when dealing with thicker or harder leather.

[0014] 2. In this utility model, when it is necessary to replace the module component, the hand-tightening bolt can be turned directly to remove the fixation of the module component, and then the required module component can be pushed into the groove and the hand-tightening bolt can be tightened. The module replacement can be completed quickly, reducing downtime. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides an aluminum composite panel core material extruder. The spiral pressure stabilizing die head structure includes a base 1. A lifting embossing adjustment assembly 2 is provided at the upper end of the base 1. The lifting embossing adjustment assembly 2 includes a fixed frame 201. Sliding frames 202 are connected to the four corners of the bottom of the fixed frame 201. A servo motor 203 is connected to the center of the top of the fixed frame 201. A threaded rod 204 is connected to the output end of the servo motor 203. A threaded post 205 is connected to the surface of the threaded rod 204. A threaded hole 206 is opened inside the threaded post 205. A pressure sensor 207 is connected to the bottom of the threaded post 205. A lifting frame 208 is connected to the bottom of the pressure sensor 207. The lifting frame 208 is connected to the four corners of the lifting frame 208. There is a slider 209. A PLC controller 211 is connected to one outer surface of the fixed frame 201. A module assembly 210 is connected to the bottom of the lifting frame 208. The PLC controller 211 is electrically connected to an external power supply through a control switch. The PLC controller 211 is electrically connected to the pressure sensor 207 and the servo motor 203. The output end of the servo motor 203 is fixedly connected to the threaded rod 204. The threaded rod 204 is threadedly connected to the threaded column 205 through the threaded hole 206. The size of the four sets of sliders 209 matches the size of the four sets of sliding frames 202. The sliders 209 and the sliding frames 202 are slidably connected.

[0020] The effect achieved in Embodiment 1 is that when embossing leather of different thicknesses, different pressures can be set according to the thickness of the leather via the PLC controller 211. After setting the pressure, the leather to be embossed is placed on the base 1, and then the PLC controller 211 is turned on. The PLC controller 211 automatically activates the reverse function of the servo motor 203, causing the output end of the servo motor 203 to drive the threaded rod 204 to rotate in the opposite direction. This allows the threaded rod 204 to rotate in the opposite direction through the threaded hole 206, thereby driving the lifting frame through the reverse thread rotation. 208 moves downward, which allows the lifting frame 208 to drive the slider 209 to slide on the surface of the sliding frame 202, pushing the module assembly 210 to perform embossing on the surface of the leather. When the pressure value of the pressure sensor 207 reaches the set pressure, the PLC controller 211 will automatically turn on the forward rotation function of the servo motor 203, driving the module assembly 210 to move upward. This completes the embossing operation of the leather, avoiding the problem that traditional embossing machines cannot adjust the pressure during embossing, which may lead to unclear pattern imprinting when facing thicker or harder leathers due to insufficient pressure.

[0021] Example 2, as Figure 1 and Figure 4 As shown, the bottom surface of the base 1 is provided with a disassembly assembly 3. The disassembly assembly 3 includes a groove 301. The lifting frame 208 is connected to the top four corners of the groove 301 with sleeves 302. The sleeves 302 are inserted with hand-tightening bolts 303. The surface of the hand-tightening bolts 303 is fixedly connected with fixing blocks 304. The module assembly 210 is provided with threaded grooves at the positions that match the four sets of hand-tightening bolts 303.

[0022] The effect achieved in Embodiment 2 is that when it is necessary to replace the module assembly 210, the module assembly 210 can be supported with one hand. The other hand can directly rotate the hand-tightening bolt 303, so that the front end of the hand-tightening bolt 303 is no longer fixed to the module assembly 210. Then, the disassembled module assembly 210 can be removed from the groove 301, and the required module assembly 210 can be pushed into the groove 301 and the hand-tightening bolt 303 can be tightened to fix it. The module replacement can be completed quickly, reducing downtime.

[0023] Working principle: When embossing leather, the embossing pressure can be adjusted according to the thickness of the leather. Then, the PLC controller 211 will start the servo motor 203, so that the module component 210 can move downward automatically to realize the embossing operation of the leather. When the pressure reaches the required squeezing, the servo motor 203 will automatically stop moving, so that the module component 210 can no longer move downward automatically, thus protecting the leather. This avoids the problem that traditional embossing machines cannot adjust the pressure during embossing, which may lead to unclear pattern imprinting due to insufficient pressure when dealing with thicker or harder leather. When it is necessary to replace the module component 210, the hand-tightening bolt 303 can be turned to release the fixation of the module component 210. Then, the required module component 210 can be pushed into the groove 301 and the hand-tightening bolt 303 can be tightened. The module replacement can be completed quickly, reducing downtime.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
