Description

Technical Field

[0001] This utility model relates to the technical field of leather drying equipment, specifically to an automotive leather drying equipment. Background Technology

[0002] In automotive construction, leather is frequently used in the interior, such as in car seats, steering wheels, door armrests, and dashboards.

[0003] During the leather manufacturing process, leather needs to undergo dyeing, washing, and other treatments. After these processes, the leather needs to be dried, and often a coating process follows. In existing technologies, the leather drying process involves placing the leather in a closed chamber and conveying it forward on a conveyor. Hot air generated by a heat source inside the chamber dries the leather on the conveyor. The dried leather then needs to be transferred to the next process for coating. To match the coating process, the conveyor speed in the drying process must be the same as that in the coating process. However, to ensure the drying effect, the conveyor for leather drying is usually designed to be quite long to allow for sufficient drying time. But excessively long drying conveyors occupy a significant amount of floor space, increasing production costs for the company. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automotive leather drying equipment to solve the problem that the existing leather drying lines are too long and occupy a large area of ​​space because they need to balance conveying speed and drying time.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] See appendix Figure 1 To be continued Figure 4 As shown, this embodiment provides an automotive leather drying equipment 100, including a housing 10, a first conveying roller assembly 70, a second conveying roller assembly 80, a heating assembly 20, an exhaust fan 30, and an exhaust pipe 40.

[0038] The outer casing 10 has an inlet 11 and an outlet 12 on one side. The inlet 11 is located below the outlet 12, and the inlet 11 and the outlet 12 are connected to the inner cavity of the outer casing 10.

[0039] The first conveying roller assembly 70 is located at the bottom of the inner cavity of the housing 10. The first conveying roller assembly 70 is at the same height as the feed inlet 11. The leather enters the upper surface of the first conveying roller assembly 70 through the feed inlet 11 and is conveyed forward by the first conveying roller assembly 70. The first conveying roller assembly 70 includes multiple conveying rollers, which are rotatably installed in the housing 10 along the length of the housing 10. The conveying rollers are driven by a motor.

[0040] The second conveyor roller assembly 80 is disposed at the upper part of the inner cavity of the housing 10. The second conveyor roller assembly 80 is arranged parallel to and above the first conveyor roller assembly 70. The rotation direction of the second conveyor roller assembly 80 is opposite to that of the first conveyor roller assembly 70, but their rotational speeds are the same. The second conveyor roller assembly 80 is at the same height as the discharge port 12, and the leather on the second conveyor roller assembly 80 is output outward through the discharge port 12. Similarly, the second conveyor roller assembly 80 includes multiple conveyor rollers, which are rotatably mounted within the housing 10 at intervals along the length of the housing 10. Each conveyor roller is also driven by a separately provided motor.

[0041] See attached document Figure 2As shown, guide rollers are respectively provided at the ends where the first conveyor roller assembly 70 and the second conveyor roller assembly 80 are connected. The guide rollers are provided to guide the leather output from the first conveyor roller assembly 70 into the upper second conveyor roller assembly 80. Specifically, a pair of first guide rollers 90 are provided at the end of the first conveyor roller assembly 70 (the leather output end), and the pair of first guide rollers 90 are arranged vertically opposite each other, with their opposite ends rotatably mounted on the housing 10. A second guide roller 110 is arranged above the input end of the second conveyor roller assembly 80 (i.e., the end of the second conveyor roller assembly 80 that is connected to the lower first conveyor roller assembly 70), with its opposite ends rotatably mounted on the housing 10. In this way, the leather is output outward through the first conveyor roller assembly 70, enters between the pair of first guide rollers 90 and is conveyed upward through the second guide roller 110 into the upper surface of the second conveyor roller assembly 80, and is then conveyed in reverse by the second conveyor roller assembly 80 and output outward from the discharge port 12.

[0042] See attached document Figure 1 Appendix Figure 2 and attached Figure 4 As shown, in this embodiment, the heating component 20 is disposed at the bottom of the inner cavity of the outer casing 10, and the heating component 20 is used to provide heated air into the inner cavity of the outer casing 10. The exhaust fan 30 is fixedly disposed at the top of the outer casing 10, and the exhaust fan 30 is connected to the top of the inner cavity of the outer casing 10, and the exhaust fan 30 is used to extract air located inside the outer casing 10. One end of the exhaust pipe 40 is connected to the exhaust fan 30, and the other end of the exhaust pipe 40 is connected to the heating component 20.

[0043] See attached document Figure 2 and attached Figure 4 As shown, the leather to be dried enters the upper surface of the first conveyor roller assembly 70 through the feed inlet 11. The first conveyor roller assembly 70 rotates, driving the leather forward for conveying. After the leather is moved to the output end of the first conveyor roller assembly 70, it enters the second conveyor roller assembly 80 through the first guide roller 90 and the second guide roller 110 for reverse conveying. Finally, under the conveying of the second conveyor roller assembly 80, the leather is output outward through the discharge outlet 12. During the movement and conveying of the leather, the heating component 20 at the bottom of the outer shell 10 heats the air and introduces the heated air into the inner cavity of the outer shell 10. The hot air at the bottom flows upward under the suction of the exhaust fan 30 at the top, exchanging heat and drying the leather on the first conveyor roller assembly 70 and the second conveyor roller assembly 80. The heated air after heat exchange enters the suction pipe under the action of the exhaust fan 30 and returns to the heating component 20 for reheating, and this cycle continues.

[0044] In this embodiment, a second conveyor roller assembly 80, arranged parallel above the first conveyor roller assembly 70, outputs the leather outward in the opposite direction. During the leather conveying process within the cavity of the outer casing 10, hot air generated by the heating assembly 20 heats and dries the leather. The parallel arrangement of the first and second conveyor roller assemblies 70 and 80 effectively shortens the overall length of the equipment, reducing the space occupied. While ensuring the leather conveying speed, it also allows for sufficient drying time within the cavity of the outer casing 10, guaranteeing the drying effect. Furthermore, by placing the first conveyor roller assembly 70 at the bottom of the cavity of the outer casing 10, the leather conveyed into the outer casing 10 initially has a higher moisture content. Simultaneously, the air at the bottom of the cavity of the outer casing 10 has higher heat, further facilitating the drying of leather with a high initial moisture content.

[0045] See attached document Figure 2 and attached Figure 4 As shown, in this embodiment, the automotive leather drying equipment 100 also includes an air conveying pipe 22, a connecting pipe 23, and multiple air guide pipes 24. The connecting pipe 23 is longitudinally installed in the inner cavity of the outer shell 10 at the bottom end of the first conveying roller assembly 70. One end of the air conveying pipe 22 is connected to the heating assembly 20, and the other end of the air conveying pipe 22 is connected to the connecting pipe 23. Multiple air guide pipes 24 are installed laterally at intervals on the connecting pipe 23. Multiple air outlet holes 241 are opened on the upper end surface of the air guide pipes 24 along their axial direction.

[0046] By arranging multiple air ducts 24 laterally in the inner cavity of the outer casing 10, the hot air generated by the heating component 20 flows into the multiple laterally arranged air ducts 24 and is sprayed outward from the air outlet 241 on the air ducts 24. Since the multiple air ducts 24 are arranged evenly in the horizontal direction, the leather can be heated evenly in the entire conveying direction, thereby improving the drying efficiency of the leather.

[0047] See attached document Figure 2 As shown, in order to improve the air output effect after the heating component 20 heats the air, a blower 21 is also provided on the air supply pipe 22. The air inlet of the blower 21 is connected to the inner cavity of the heating component 20, and the air outlet of the blower 21 is connected to the air supply pipe 22. The blower 21 can quickly send the hot air heated by the heating component 20 into the output pipe, and then into multiple air guide pipes 24 through the air supply pipe 22, and then spray it out into the inner cavity of the outer shell 10 through the air guide pipes 24.

[0048] See attached document Figure 2 and attached Figure 4As shown, in this embodiment, the automotive leather drying equipment 100 further includes a drying chamber 50, which is filled with a desiccant for absorbing and recovering moisture from the air. The drying chamber 50 is installed on the exhaust duct 40 at a position between the exhaust fan 30 and the heating assembly 20. Specifically, the drying chamber 50 is filled with a desiccant for absorbing and recovering moisture from the air; for example, activated alumina desiccant can be used, which is heat-resistant and low-cost. The drying chamber 50 is installed on the exhaust duct 40 at a position between the exhaust fan 30 and the heating assembly 20.

[0049] See attached document Figure 4 As shown, in this embodiment, the top of the outer shell 10 has a triangular cross-section that is narrower at the top and wider at the bottom. The upper surface of the outer shell 10 is provided with an upwardly protruding air collection groove 60, and the air outlet of the exhaust fan 30 is connected to the air collection groove 60.
