Technical Field

[0001] This utility model relates to the technical field of cowhide production equipment, and in particular to a double-sided roller coating machine for functional cowhide production. Background Technology

[0002] Roller coating machines for cowhide production are widely used finishing equipment in leather product manufacturing. Their main function is to evenly coat the surface of cowhide with coatings and other substances to achieve both protection and aesthetic enhancement. Through its specific design and operating mechanism, the roller coating machine ensures rapid, uniform, and clean application of coatings to the leather surface, resulting in a high degree of uniformity in color and texture. The application of roller coating machines in cowhide production not only improves production efficiency and reduces production costs but also significantly reduces coating waste. Roller coating machines for cowhide production are indispensable equipment in the leather industry; their high efficiency, uniformity, and adaptability make them a key factor in improving the quality and production efficiency of leather products. However, existing roller coating machines can only coat cowhide of fixed widths, lacking flexibility and failing to meet diverse processing needs, thus presenting certain drawbacks in their use.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The technical solution adopted by this utility model is as follows: It includes an operating base, the top of which has a limiting groove. A width adjustment component is installed in the limiting groove. A first mounting side plate and a second mounting side plate are installed on the width adjustment component. Both the first and second mounting side plates have embedding slots. A positioning connecting block is inserted into each embedding slot. The positioning connecting blocks on both sides are fixedly connected to the first and second mounting side plates respectively via a pull-type pin connecting component. An upper coating roller and a lower coating roller are installed on the positioning connecting block. The upper and lower coating rollers are symmetrically distributed, and both are rotatably connected to the positioning connecting block via a rotating connecting shaft.

[0007] Preferably, in order to drive the threaded slider to slide in the limiting groove by controlling the rotation of the bidirectional threaded rod, the threaded slider is installed on the bidirectional threaded rod, and the threaded slider is slidably engaged in the limiting groove.

[0008] Preferably, in order to enable the two threaded sliders to slide in opposite directions in the limiting groove to adjust the distance between the first mounting side plate and the second mounting side plate, there are two threaded sliders, each located at the opposite thread end of the bidirectional threaded rod, and the first mounting side plate and the second mounting side plate are respectively fixedly connected to the two threaded sliders.

[0009] Preferably, in order to enable the positioning connecting block to be fixedly connected to the first mounting side plate and the second mounting side plate via the connecting pin rod, the pull-out pin connecting assembly includes the L-shaped mounting bracket, which is fixed to the first mounting side plate and the second mounting side plate.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5As shown, this embodiment provides a double-sided roller coating machine for functional cowhide production, including an operating base 1. A limiting groove is formed on the top of the operating base 1, and a width adjustment component 2 is installed in the limiting groove. A first mounting side plate 3 and a second mounting side plate 4 are installed on the width adjustment component 2. Both the first mounting side plate 3 and the second mounting side plate 4 have embedding slots, into which positioning connecting blocks 5 are inserted. The positioning connecting blocks 5 on both sides are fixedly connected to the first mounting side plate 3 and the second mounting side plate 4 respectively via a pull-type pin connecting component 6. An upper roller coating cylinder 7 and a lower roller coating cylinder 8 are installed on the positioning connecting block 5. The upper roller coating cylinder 7 and the lower roller coating cylinder 8 are symmetrically distributed, and both are rotatably connected to the positioning connecting block 5 via a rotating connecting shaft 9. In use, according to the width requirements of the cowhide, the width adjustment component 2 is adjusted through the limiting groove on the top of the operating base 1, thereby adjusting the width of the first roller coating cylinder 7. After adjusting the distance between the mounting side plate 3 and the second mounting side plate 4, insert the positioning connecting block 5 into the embedded slot on the first mounting side plate 3 and the second mounting side plate 4. Then, use the pull-type pin connecting assembly 6 to firmly fix the positioning connecting blocks 5 on both sides to the first mounting side plate 3 and the second mounting side plate 4 respectively. Install the upper roller coating cylinder 7 and the lower roller coating cylinder 8 on the positioning connecting block 5 respectively. They can rotate flexibly with the positioning connecting block 5 by rotating the connecting shaft 9 to ensure that the functional coating can be evenly applied during the roller coating process. After the adjustment is completed, start the machine and feed the cowhide to be processed into the double-sided roller coating machine. The upper roller coating cylinder 7 and the lower roller coating cylinder 8 simultaneously perform double-sided roller coating on the cowhide to complete the uniform coating of the functional coating. The operation is simple and the adjustment is flexible. It is easy to replace the upper roller coating cylinder 7 and the lower roller coating cylinder 8 with different widths and is suitable for the production needs of cowhide of different widths.

[0022] The width adjustment assembly 2 includes a servo motor 201 and a bidirectional threaded rod 202. The servo motor 201 is fixed to the inner wall of one end of the limiting slide groove. The bidirectional threaded rod 202 is rotatably mounted on the inner wall of the other end of the limiting slide groove via a rotating joint 203. One end of the bidirectional threaded rod 202 is fixedly connected to the output shaft of the servo motor 201. Two threaded sliders 204 are mounted on the bidirectional threaded rod 202, and these sliders are slidably engaged in the limiting slide groove. The two threaded sliders 204 are located at the opposite thread ends of the bidirectional threaded rod 202, and the first mounting side plate 3 and the second mounting side plate 4 are fixedly connected to the two threaded sliders 204. In use, by starting the servo motor 201, its output shaft will move... Force is transmitted to the bidirectional threaded rod 202, causing it to rotate under the support of the rotary joint 203. Since the bidirectional threaded rod 202 has reverse threads, when the servo motor 201 drives it to rotate, the two threaded sliders 204 will move in opposite directions along the limiting groove. These two threaded sliders 204 respectively carry the first mounting side plate 3 and the second mounting side plate 4. Therefore, as the threaded sliders 204 move, the distance between the first mounting side plate 3 and the second mounting side plate 4 will increase or decrease accordingly, thereby achieving width adjustment. The width between the first mounting side plate 3 and the second mounting side plate 4 can be precisely adjusted by controlling the forward and reverse rotation of the servo motor 201 to meet the required installation or working requirements.

[0023] The pull-out pin connection assembly 6 includes an L-shaped mounting bracket 601, which is fixed to the first mounting side plate 3 and the second mounting side plate 4. A connecting pin rod 602 is slidably mounted on the L-shaped mounting bracket 601. One end of the connecting pin rod 602 is inserted into a corresponding connecting pin hole on the first mounting side plate 3, the second mounting side plate 4, and the positioning connecting block 5. A pull handle 603 is fixedly mounted on the other end of the connecting pin rod 602. A drive bar 60 is fixedly mounted on the connecting pin rod 602. 4. One end of the drive block 604 is slidably sleeved on the limiting slide rod 605 installed on the inner wall of the L-shaped mounting bracket 601. The drive block 604 is elastically connected to the inner wall of the L-shaped mounting bracket 601 through the drive spring 606. In use, by holding the lifting handle 603, the connecting pin rod 602 can be easily pulled out from the connecting pin hole on the first mounting side plate 3, the second mounting side plate 4 and the positioning connecting block 5, so as to realize the quick separation of the positioning connecting block 5 from the first mounting side plate 3 and the second mounting side plate 4. When reconnection is required, the user simply presses the lifting handle 603 downwards, aligning the other end of the connecting pin 602 with and inserting it into the corresponding connecting pin hole, thus completing the secure connection of the positioning connecting block 5. Throughout the operation, the drive block 604 slides smoothly on the limit slide bar 605, ensuring the stability and smoothness of the connecting pin 602. At the same time, the drive spring 606 provides appropriate elasticity to the connecting pin 602, allowing it to fit tightly in the connecting pin hole, enhancing the stability and safety of the connection.
