[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned problems of inconvenience in printing patterns on both sides of artificial leather, low production efficiency, and difficulty in cooling and shaping the pressed artificial leather, which easily leads to insufficient pattern durability, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide an improved artificial leather pattern printing device, which facilitates the control of pattern printing on both sides or one side of artificial leather, effectively improves production efficiency, facilitates preheating of artificial leather, facilitates cooling and shaping of pressed artificial leather, and makes the pattern more durable.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] An improved artificial leather pattern printing device includes a fixed frame. Two conveying rollers are located at one end of the inner wall of the fixed frame. An imprinting assembly is located on the side wall of the fixed frame. The imprinting assembly includes a hydraulic cylinder. A moving block is located at the output end of the hydraulic cylinder. A clamping plate is slidably connected to the inner wall of the moving block. A lever is located on the side wall of the clamping plate. Two rotating shafts are slidably connected to the side wall of the fixed frame. Each of the two rotating shafts has a heat-printing roller on its outer circumference. Moving plates are rotatably connected to both ends of the outer circumference of the two rotating shafts. Each of the moving plates has a slot on its side wall. A motor is located on the side wall of each moving plate at one end of each of the two rotating shafts. Two guide rollers are located at the other end of the inner wall of the fixed frame. A temperature regulating assembly is located at one end of the inner wall of the fixed frame. The hydraulic cylinder and motor are electrically connected to an external power source. The heat-printing rollers are existing technology, facilitating heating and making imprinting easier and the patterns clearer.

[0012] In a preferred embodiment of an improved artificial leather pattern printing device according to this utility model, the temperature control component includes a semiconductor cooling chip. Each semiconductor cooling chip has heat sinks on both sidewalls, and each of the two heat sinks has a fan on its other sidewall. Each of the two fans has an air duct at its output end, and each of the two air ducts has a branch pipe at its other end. Multiple nozzles are located at the top and bottom of the branch pipe's inner cavity. The semiconductor cooling chip and fans are electrically connected to an external power supply. The fans drive airflow, which is then ejected from the nozzles, simultaneously blowing away dust from the surface of the artificial leather and preventing dust accumulation inside the printed pattern from affecting the quality of the finished product.

[0013] As a preferred embodiment of an improved artificial leather pattern printing device of this utility model, the fixing frame is provided with fixing plates on both side walls, and the top of the fixing plates is fixedly connected to the hydraulic cylinder.

[0014] In a preferred embodiment of an improved artificial leather pattern printing device of this utility model, the length of the card plate is greater than the width of the moving block, and the size and position of the card plate match the size and position of the card slot.

[0015] In a preferred embodiment of an improved artificial leather pattern printing device of this utility model, the height of the higher guide roller is matched with the height of the higher conveying roller, and the height of the bottom of the outer circumference of the lower guide roller is matched with the height of the top of the outer circumference of the lower conveying roller.

[0016] In a preferred embodiment of this improved artificial leather pattern printing device, the heat sink is made of copper-zinc alloy, and the two fan output ends face opposite directions. The fins of the heat sink are arranged at intervals to facilitate airflow through the gaps, thus forming an air circulation channel.

[0017] As a preferred embodiment of an improved artificial leather pattern printing device of this utility model, the inner wall of the fixed frame is provided with two pressure rollers, the size and position of which match the size and position of the heat printing roller.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This improved artificial leather pattern printing device uses conveyor rollers to transport artificial leather. When single-sided printing is required, a toggle block is moved to move the card plate away from one slot and into another. The hydraulic cylinder is opened to move the moving block, which in turn moves the card plate and the moving plate, causing the rotating shaft to move the hot printing roller to the desired position. The motor is then turned on to rotate the hot printing roller and print on the artificial leather. When double-sided printing is required, the toggle block is moved to the middle so that both ends of the card plate enter the two slots respectively. The hydraulic cylinder is opened to move the two hot printing rollers simultaneously, facilitating double-sided printing and effectively improving printing efficiency.

[0021] This improved artificial leather pattern printing device lowers the temperature of the cold end by activating a semiconductor cooling chip, thereby lowering the temperature of the heat sink attached to the cold end. By turning on a fan, airflow is drawn into the air duct, allowing the cold air to enter the distribution pipe and be sprayed out from the nozzle to cool and shape the printed artificial leather, effectively improving the durability of the pattern. The hot end of the semiconductor cooling chip raises the temperature of the heat sink attached to the hot end, and another fan drives hot air to preheat and soften the unprinted artificial leather, effectively improving the printing effect and saving energy.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an improved artificial leather pattern printing device according to one embodiment, including:

[0035] Please see Figures 1-5 An improved artificial leather pattern printing device according to this embodiment includes a fixed frame 1. Two conveying rollers 2 are rotatably connected to one end of the inner cavity sidewall of the fixed frame 1. An imprinting assembly 3 is fixedly mounted on the sidewall of the fixed frame 1. The imprinting assembly 3 includes a hydraulic cylinder 301. A moving block 302 is fixedly mounted at the output end of the hydraulic cylinder 301. A clamping plate 303 is slidably connected to the inner cavity sidewall of the moving block 302. A lever 304 is fixedly mounted on the sidewall of the clamping plate 303. Two rotating shafts 305 are slidably connected to the sidewall of the fixed frame 1. A heat printing roller 306 is fixedly mounted on the outer circumference of each of the two rotating shafts 305. Moving plates 307 are rotatably connected to both ends of the outer circumference of each of the two rotating shafts 305. A slot 308 is opened on the sidewall of each of the two moving plates 307. A motor 309 located on the sidewall of the moving plate 307 is fixedly mounted at one end of each of the two rotating shafts 305. Two guide rollers 4 are rotatably connected to the other end of the inner cavity sidewall of the fixed frame 1. A temperature regulating component 5 is fixedly installed at one end of the inner wall of the fixed frame 1. The hydraulic cylinder 301 and the motor 309 are electrically connected to an external power source. The artificial leather is conveyed through the conveying roller 2. When it is necessary to print on one side of the artificial leather, the toggle block 304 is moved to move the card plate 303 away from one of the card slots 308 and into the other card slot 308. The hydraulic cylinder 301 is opened to move the moving block 302, thereby moving the card plate 303 and the moving plate 307. Then, the rotating shaft 305 moves the hot printing roller 306 to the required position. The motor 309 is opened to rotate the hot printing roller 306 to print on the artificial leather. When it is necessary to print on both sides of the artificial leather, the toggle block 304 is moved to the middle so that the two ends of the card plate 303 enter the two card slots 308 respectively. The hydraulic cylinder 301 is opened to move the two hot printing rollers 306 at the same time, which facilitates double-sided printing and effectively improves printing efficiency.

[0036] It is worth noting that, in order to facilitate the cooling and shaping of the artificial leather after printing, the temperature control component 5 specifically includes a semiconductor cooling chip 501. Heat sinks 502 are bonded to both side walls of the semiconductor cooling chip 501. A fan 503 is fixed to the other side wall of each of the two heat sinks 502. Air ducts 504 are fixed to the output ends of each of the two fans 503. A branch pipe 505 is welded to the other end of each air duct 504. Multiple nozzles 506 are fixed to the top and bottom of the inner cavity of the branch pipe 505. The semiconductor cooling chip 501 and the fans 503 are electrically connected to an external power supply. The semiconductor cooling chip 501 lowers the temperature of the cold end, thereby lowering the temperature of the heat sink 502 attached to the cold end. The fan 503 then turns on, causing airflow into the air duct 504, which in turn causes the cold air to enter the distribution pipe 505 and be ejected from the nozzle 506 to cool and set the printed artificial leather, effectively improving the durability of the pattern. The hot end of the semiconductor cooling chip 501 raises the temperature of the heat sink 502 attached to the hot end, and another fan 503 drives hot air to preheat and soften the unprinted artificial leather, effectively improving the printing effect and saving energy.

[0037] Next, in order to prevent the hydraulic cylinder 301 from falling, the fixing plate 310 is fixedly installed on both sides of the fixing frame 1. The top of the fixing plate 310 is fixedly connected to the hydraulic cylinder 301. The fixing plate 310 fixedly connected to the hydraulic cylinder 301 can improve the stability of the hydraulic cylinder 301 and prevent it from falling.

[0038] Meanwhile, in order to make the movement of the movable plate 307 more stable, specifically, the length of the clamping plate 303 is greater than the width of the movable block 302, and the size and position of the clamping plate 303 match the size and position of the slot 308. With the clamping plate 303 being longer than the movable block 302, it is easy to move the clamping plate 303 to the middle so that two movable plates 307 can be clamped at the same time. With the clamping plate 303 matching the size and position of the slot 308, it is easy to make the clamping plate 303 and the slot 308 clamp more tightly, and avoid the movable plate 307 shaking and affecting stability.

[0039] Furthermore, in order to facilitate the formation of the artificial leather conveying track, specifically, the height of the high guide roller 4 is matched with the height of the high conveying roller 2, and the height of the bottom of the outer circumference of the low guide roller 4 is matched with the height of the top of the outer circumference of the low conveying roller 2. With the guide roller 4 matching the height of the conveying roller 2, it is convenient for the artificial leather to be discharged from the top of the high conveying roller 2, around the two guide rollers 4, and then from the top of the low conveying roller 2 for collection.

[0040] It is worth noting that, in order to facilitate the separate flow of cold and hot air, the heat sink 502 is made of copper-zinc alloy, and the two fans 503 have opposite output directions. The copper-zinc alloy heat sink 502 effectively improves the heat dissipation effect, and the two fans 503 with opposite output directions facilitate the flow of cold and hot air into the two air ducts 504 respectively.

[0041] Finally, to facilitate pattern printing, specifically, two pressure rollers 6 are rotatably connected to the inner wall of the fixed frame 1. The size and position of the pressure rollers 6 match the size and position of the hot printing roller 306. By using the pressure rollers 6 that match the size and position of the hot printing roller 306, it is easy for the pressure rollers 6 to abut against the hot printing roller 306 and clamp the artificial leather, making it convenient to cooperate with the hot printing roller 306 to print patterns.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0047] Fan 503: DE07020B12U-FAR.

[0048] Combination Figures 1-5 The improved artificial leather pattern printing device of this embodiment is used in the following specific process:

[0049] 1: When the artificial leather pattern printing device that requires improvement of this device is used, the conveyor roller 2 conveys the artificial leather. When it is necessary to print on one side of the artificial leather, the toggle block 304 is moved to drive the card plate 303 to move out of one of the card slots 308 and into the other card slot 308. The hydraulic cylinder 301 is started to move the moving block 302 and drive the moving plate 307 to move, so that the rotating shaft 305 drives the hot printing roller 306 to move to the required position. The motor 309 is started to drive the hot printing roller 306 to rotate and print on the artificial leather. When it is necessary to print on both sides of the artificial leather, the toggle block 304 is moved to the middle so that the two ends of the card plate 303 enter the two card slots 308 respectively. The hydraulic cylinder 301 is started to drive the two hot printing rollers 306 to move simultaneously to print on both sides.

[0050] 2: Activating the semiconductor cooling chip 501 lowers the temperature of the heat sink 502 attached to the cold end, and activating the fan 503 drives airflow into the air duct 504, thereby allowing cold air to enter the distribution pipe 505 and be sprayed out from the nozzle 506 to cool and shape the printed artificial leather. The hot end of the semiconductor cooling chip 501 raises the temperature of the heat sink 502 attached to the hot end, and another fan 503 drives hot air to preheat and soften the unprinted artificial leather.
