Description

Technical Field

[0001] This invention relates to the field of leather processing technology, specifically to a small embossing machine for processing artificial leather. Background Technology

[0002] As a high-quality alternative to natural leather, artificial leather is widely used in various fields such as bag manufacturing, shoe material production, clothing decoration, home furnishing, and handicrafts due to its advantages of low cost, convenient processing, and strong appearance plasticity. With the continuous improvement of consumer demand for personalized and diversified products, the textural decoration of artificial leather surfaces has become a key process for enhancing product added value. Embossing is the core means to achieve this decorative effect. Through embossing, artificial leather can present various textures such as grain, lychee grain, and crocodile grain, mimicking natural leather, to meet the design needs of different products.

[0003] Currently, artificial leather embossing equipment is widely used in the industry, and can be divided into large-scale industrial embossing machines and small-scale processing embossing machines according to the processing scale. To adapt to small-scale processing scenarios, some small artificial leather embossing machines have appeared on the market, mainly including manual embossing machines, simple automatic embossing machines, ultrasonic embossing machines, and pneumatic embossing machines.

[0004] However, existing small embossing machines still have many technical defects and cannot fully meet actual processing needs. For the flexibility requirements of small batch processing scenarios, the mold changing structure of existing small embossing machines is mostly cumbersome, and it takes a long time to change embossing molds with different textures. Therefore, we propose a small embossing machine for processing artificial leather. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a small-scale embossing machine for processing artificial leather, which solves the problem of long processing time when changing embossing molds with different textures.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a small artificial leather embossing machine, comprising a mounting plate and a mold plate disposed on one side of the mounting plate. A bottom shell is mounted on the side of the mounting plate opposite to the mold plate, and the mounting plate is located at the inner top of the bottom shell and is detachably installed with the bottom shell. A heat-conducting plate is fixedly connected to the side of the mounting plate opposite to the bottom shell, and the bottom end of the heat-conducting plate has a hollow structure. A heating element is provided on the inner wall of the bottom shell facing the heat-conducting plate, and the heating element is fixedly connected to the bottom end of the inner wall of the heat-conducting plate. A placement groove is opened on the side of the mold plate opposite to the heat-conducting plate, and the placement groove is located at the center of the mold plate and is groove-shaped. The heat-conducting plate extends to the bottom end of the mold plate and is fixedly attached to the mold plate. A pressure plate is arranged parallel to the side of the mold plate opposite to the bottom shell.

[0009] Preferably, the mold plate has two sets of side plates integrally formed on the outer side wall opposite to the heat-conducting plate, and the side plates are connected to the mounting plate and have limit bolts installed through them.

[0010] Preferably, a limiting component is fixedly connected to the side of the mounting plate opposite to the limiting bolt, and the limiting bolt extends into the limiting component and is rotatably connected to it.

[0011] Preferably, an auxiliary plate is arranged parallel to the side of the pressure plate away from the mold plate. Four sets of spring rods are installed through and fixedly mounted on the auxiliary plate at the four corners away from the pressure plate. The four sets of spring rods are evenly distributed in a direction perpendicular to the auxiliary plate, and each spring rod is inserted into the top end face of the pressure plate on the side facing the pressure plate.

[0012] Preferably, a docking plate is arranged parallel to the side of the auxiliary plate away from the pressure plate, and two sets of sliding rods are installed opposite each other on the bottom end face of the docking plate facing the auxiliary plate.

[0013] Preferably, one end of the slide rod facing the auxiliary plate is fixedly connected to the auxiliary plate, and the other end of the slide rod facing the docking plate passes through and is movably connected to the docking plate.

[0014] Preferably, the docking plate is provided with a cylinder on the side opposite to the pressure plate. The output end of the cylinder is arranged in a direction perpendicular to the docking plate, and the output end of the cylinder passes through the center of the docking plate and is detachably and fixedly connected to the auxiliary plate.

[0015] Preferably, a mounting bracket is fixedly installed on the side of the cylinder component away from the pressure plate, and a top bracket rod is provided on the side of the mounting bracket perpendicular to the cylinder component, with the top bracket rod inserted into the mounting bracket facing the side of the mounting bracket.

[0016] Preferably, the top support rod has an integrally formed side bracket on the side away from the mounting plug, the side bracket is fixedly connected to the bottom shell on the side facing the bottom shell, and a heat dissipation mechanism is inserted and installed on the side of the bottom shell away from the top support rod.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] In this invention, the bottom shell serves as the core load-bearing component. A mounting plate is fixedly installed at its top, ensuring the stability of subsequent component installation and providing fundamental support for the precision of the embossing process. A mold plate is correspondingly positioned on the top of the mounting plate, forming a mutually compatible assembly. To achieve the temperature control required for embossing, a heat-conducting plate is fixedly connected to the side of the mounting plate facing the mold plate. The bottom of the heat-conducting plate features a hollow structure, which reduces the overall weight of the component and improves the uniformity of heat conduction, preventing localized overheating from affecting the processing quality of the artificial leather.

[0019] To meet the temperature control requirements of the heat-conducting plate, a heat dissipation mechanism is installed on the inner wall of the bottom shell facing the heat-conducting plate. This mechanism works in conjunction with the heat-conducting plate to regulate its operating temperature in real time, preventing overheating due to continuous heating, ensuring temperature stability during the embossing process, and extending the service life of the core components of the equipment. To further improve heat conduction efficiency and assembly compatibility, the bottom of the mold plate also adopts a hollow structure design, and the heat-conducting plate extends precisely into the hollow cavity at the bottom of the mold plate. Efficient heat conduction is achieved through surface contact, ensuring uniform temperature across the entire mold plate and guaranteeing clear embossing texture.

[0020] To accommodate small-batch, customized processing needs, a placement slot is provided on the side of the mold plate away from the heat-conducting plate. This slot features a precise dimensional design, allowing for convenient and rapid placement and replacement of different embossing plates without disassembling the entire mold plate, significantly reducing mold changeover time and improving processing efficiency. Furthermore, the mold plate supports complete customization and replacement, allowing for the matching of mold plates of corresponding specifications to meet the processing requirements of embossing plates of different sizes. This effectively broadens the processing adaptability of the equipment, satisfying the diverse embossing processing needs of small and micro enterprises and customized production scenarios, enhancing the practicality and flexibility of the equipment.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] refer to Figures 1-6 The small artificial leather embossing machine shown includes a mounting plate 2 and a mold plate 3 disposed on one side of the mounting plate 2. A specific embodiment is shown below:

[0030] Example 1

[0031] The mounting plate 2 is mounted on the side opposite to the mold plate 3, with the bottom shell 1 attached. The mounting plate 2 is precisely positioned inside the top of the bottom shell 1, and the two are connected in a detachable manner. This detachable design facilitates later maintenance and repair of the equipment, and allows for flexible adjustment of the mounting plate 2's position according to actual processing needs, improving the equipment's adaptability. A heat-conducting plate 201 is fixedly connected to the side of the mounting plate 2 opposite to the bottom shell 1. The bottom of the heat-conducting plate 201 features a hollow structure. This structure not only reduces the overall weight of the component and the load on the equipment, but also increases the heat conduction area, improves the uniformity of heat diffusion, and avoids localized heat accumulation that could adversely affect processing.

[0032] To achieve the temperature control required for embossing, a heating element 101 is installed on the inner wall of the bottom shell 1 facing the heat conduction plate 201. The heating element 101 is fixedly connected to the bottom of the inner wall of the heat conduction plate 201, ensuring that the heat generated by the heating element 101 can be quickly and efficiently conducted to the heat conduction plate 201, thereby providing stable temperature support for subsequent embossing. At the same time, a heat dissipation mechanism 102 is installed on the side of the bottom shell 1 away from the top support rod 601 using an insert installation method. This heat dissipation mechanism 102 and the heating element 101 form a coordinated temperature control system, which can dissipate excess heat generated during equipment operation in real time, preventing the internal temperature of the bottom shell 1 from becoming too high and damaging the components, and ensuring the long-term stable operation of the equipment.

[0033] Example 2

[0034] A placement groove 301 is provided on the side of the mold plate 3 opposite to the heat-conducting plate 201. The placement groove 301 is precisely located at the center of the mold plate 3 and is a regular groove shape. The dimensions of the placement groove 301 are precisely designed to fit and accommodate embossing plates with different patterns, enabling quick changes in embossing patterns and meeting personalized processing needs. To ensure temperature uniformity during the embossing process, the heat-conducting plate 201 extends to the bottom of the mold plate 3 and is fixedly attached to the mold plate 3, ensuring that the heat transferred by the heat-conducting plate 201 can fully and evenly cover the mold plate 3, improving the embossing quality. To achieve a stable connection and precise positioning between the mold plate 3 and the mounting plate 2, two sets of side plates 302 are integrally formed on the outer side wall of the mold plate 3 opposite to the heat-conducting plate 201, ensuring balanced force distribution.

[0035] A limiting bolt 303 is movably mounted through the side plate 302 facing the mounting plate 2. Correspondingly, a limiting component 202 is fixedly connected to the side of the mounting plate 2 opposite to the limiting bolt 303. The limiting bolt 303 extends into the limiting component 202 and is rotatably connected to it. By rotating the limiting bolt 303, the tightness of the fit between the mold plate 3 and the mounting plate 2 can be adjusted, ensuring the stability of the connection between the two and facilitating the later disassembly of the mold plate 3 for overall replacement, adapting to the processing needs of embossed plates of different sizes.

[0036] Example 3

[0037] A pressure plate 4 is arranged parallel to the side of the mold plate 3 opposite to the bottom shell 1. The pressure plate 4 maintains a precise parallel relationship with the mold plate 3 to ensure uniform pressure application during the embossing process. An auxiliary plate 401 is arranged parallel to the side of the pressure plate 4 opposite to the mold plate 3. Four sets of spring rods 404 are installed through and fixedly mounted on the four corners of the auxiliary plate 401 opposite to the pressure plate 4. The four sets of spring rods 404 are evenly distributed in a direction perpendicular to the auxiliary plate 401 to ensure balanced force on the pressure plate 4. Each spring rod 404 is inserted into the top end face of the pressure plate 4 on the side facing the pressure plate 4. The spring rods 404 have good elastic buffering performance and can play a buffering role during the embossing process to avoid sudden pressure increases that could damage the artificial leather or the embossing plate. A docking plate 402 is arranged parallel to the side of the auxiliary plate 401 opposite to the pressure plate 4. Two sets of sliding rods 403 are installed opposite each other on the bottom end face of the docking plate 402 facing the auxiliary plate 401. One end of the sliding rod 403 facing the auxiliary plate 401 is fixedly connected to the auxiliary plate 401, and the other end of the sliding rod 403 passes through and is movably connected to the docking plate 402. The sliding fit structure between the sliding rod 403 and the docking plate 402 provides precise guidance for the up and down movement of the auxiliary plate 401, preventing the auxiliary plate 401 from deviating during movement, thereby ensuring the accuracy of the pressure applied by the pressure plate 4 and improving the embossing quality.

[0038] Example 4

[0039] A cylinder component 5 is located on the side of the docking plate 402 opposite to the pressure plate 4. As the core power component, the cylinder component 5 has its output end positioned perpendicular to the docking plate 402, ensuring precise power transmission. The output end of the cylinder component 5 passes through the center of the docking plate 402 and is detachably fixedly connected to the auxiliary plate 401. This connection method ensures the stability of power transmission and facilitates future maintenance and replacement of the cylinder component 5 or the auxiliary plate 401. To ensure stable installation of the cylinder component 5, a mounting insert 501 is fixedly installed on the side of the cylinder component 5 opposite to the pressure plate 4. A top support rod 601 is located on the side of the mounting insert 501 perpendicular to the cylinder component 5. The top support rod 601 is inserted into the mounting insert 501. This insert-type assembly structure not only facilitates assembly but also ensures the stability of the support provided by the top support rod 601 to the mounting insert 501, thus providing a stable installation base for the cylinder component 5, preventing shaking during operation, and ensuring smooth power output.

[0040] Example 5

[0041] The top support rod 601, on the side facing away from the mounting plug 501, is connected to the side bracket 6 using an integrated molding process. This integrated structure eliminates the need for additional assembly, simplifying the manufacturing process and significantly improving the connection strength between the top support rod 601 and the side bracket 6, ensuring the stability of the support structure. The side bracket 6, facing the bottom shell 1, is fixedly connected to it, achieving a stable connection between the top support rod 601 and the bottom shell 1, forming a complete force-bearing system between the load-bearing components and the power support components. This structural design can evenly transmit the reaction force generated during the operation of the cylinder component 5 to the bottom shell 1, avoiding excessive local stress that could lead to component deformation, ensuring the stability and service life of the overall equipment structure, and also providing a reliable structural foundation for the precise coordination of various components.

[0042] Working principle of this invention:

[0043] Before processing, according to the requirements, the embossed plate with the corresponding pattern is placed in the placement groove 301 of the mold plate 3. By rotating the limiting bolt 303 on the side plate 302, the fit between the mold plate 3 and the mounting plate 2 is adjusted by the rotation cooperation between the limiting bolt 303 and the limiting part 202, so as to achieve precise positioning of the mold. If it is necessary to adapt to embossed plates of different sizes, the mold plate 3 can be directly disassembled and replaced as a whole.

[0044] After the equipment is started, the heating element 101 inside the bottom shell 1 begins to work, and the heat is evenly conducted to the mold plate 3 through the hollow cavity of the heat conduction plate 201. At the same time, the heat dissipation mechanism 102 dissipates excess heat in real time to maintain the stable temperature required for processing. Subsequently, the artificial leather to be processed is laid on the surface of the embossed plate, and the cylinder 5 starts to output power. Its output end pushes the auxiliary plate 401 to move smoothly downward along the guide direction of the slide bar 403.

[0045] The auxiliary plate 401 drives the pressure plate 4 to move downwards synchronously via the spring rods 404 at its four corners. The spring rods 404 act as a buffer during the pressure application process, preventing sudden pressure increases that could damage the leather or the embossing plate. After the pressure plate 4 is parallel and attached to the mold plate 3, pressure is applied evenly, causing the artificial leather to adhere to the embossing plate and form under the combined action of temperature and pressure. After processing is completed, the cylinder 5 drives all components to reset, and the formed leather can be removed to complete a single processing cycle. The entire process relies on the precise coordination of each component to ensure both embossing quality and processing efficiency.

[0046] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
