Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a coating machine for the production of artificial synthetic leather. Background Technology

[0002] Artificial leather, often simply referred to as synthetic leather or artificial leather, is a material made of synthetic materials that can replace natural leather. Through advanced manufacturing technology and material selection, it successfully simulates the appearance and texture of natural leather and has significant advantages in terms of cost, sustainability, and design flexibility. As a result, it has been widely used and accepted in modern industrial and consumer markets.

[0003] During the production of synthetic leather, a coating machine is often used to apply adhesive to the surface of the synthetic leather. Chinese patent CN221268837U discloses this technology. It utilizes a fan to deliver hot air to the inner cavity of a blower mechanism, which then blows hot air onto the surface of the synthetic leather through the output end of the blower mechanism. This accelerates the drying of the coating and prevents the coating from detaching from the leather surface due to contact with foreign objects while the leather is being moved, especially if the coating is not fully dried.

[0004] Existing coating machines use rotating rollers to carry leather through a coating chamber. After the leather is coated by a coating plate on the coating chamber, it is conveyed by rotating rollers and then wound up after drying. However, leathers of different thicknesses have different amounts of residual glue on their surface after passing through the coating plate, resulting in coating residue on the leather surface after drying, which affects the leather processing effect. Utility Model Content

[0005] In view of the problem that the amount of residual glue on the surface of leathers of different thicknesses varies after passing through the coating plate, resulting in coating residue on the leather surface after drying, which affects the leather processing effect, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a coating machine for the production of synthetic leather, which aims to change the distance between the glue removal plate on the baffle connected by the threaded shaft and the leather, thereby adapting to the glue removal needs of leathers of different thicknesses.

[0017] The beneficial effects of this utility model are:

[0018] 1.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figure 1-5 This is the first embodiment of the present invention, providing a coating machine for producing synthetic leather. The coating machine includes a base 1 and a coating chamber 2. The coating chamber 2 is disposed on the surface of the base 1. A cleaning component 3 and a conveying component 4 are disposed on the top of the base 1. The cleaning component 3 is located on the top of the coating chamber 2 and includes a glue-removing component 31. The glue-removing component 31 includes a baffle 311, which is perpendicular to the base 1. A glue-removing plate 312 is fixedly installed on the outer side of the baffle 311, and the glue-removing plates 312 are distributed on both sides of the baffle 311. A sleeve 313 is fixedly installed on the top of the coating chamber 2. A threaded ring 315 is movably connected to the inner side of the sleeve 313. The threaded ring 315 is threadedly connected to a threaded shaft 314. One end of the threaded shaft 314, passing through the threaded ring 315, is connected to the baffle 311. A motor 316 is fixedly installed at one end of the cylinder 313. The output end of the motor 316 is connected to the outside of the threaded ring 315. The glue-applying chamber 2 is embedded in the surface of the machine base 1 and is filled with paint glue. When applying glue, the leather is completely immersed in the glue-applying chamber 2. The baffle 311 can move in a direction that is always perpendicular to the machine base 1. One end of the glue-removing plate 312 is tilted towards the side close to the baffle 311, so as to better fit the leather and scrape the glue off the leather surface. The inner side of the threaded ring 315 is opened with threads that are compatible with the threaded shaft 314 and can be driven by the output shaft of the motor 316 to rotate in the sleeve 313. When the threaded ring 315 rotates, the length of the threaded shaft 314 protruding from the sleeve 313 increases, thereby changing the contact distance between the baffle 311 and the leather, so as to adapt to the scraping of glue on leather of different thicknesses.

[0032] The bottom of the glue removal plate 312 is provided with a drainage pipe 317, and the other end of the drainage pipe 317 is provided with a filter box 318. The filter box 318 is located at the top of the glue coating chamber 2. The drainage pipe 317 can collect the scraped glue through the inclined angle set between the glue removal plate 312 and the baffle 311. The filter box 318 can filter the glue and send it back into the glue coating chamber 2.

[0033] The cleaning component 3 also includes a drying component 32, which includes a blower box 321. The blower box 321 is fixedly installed on the top of the base 1. An upper pull roller 322 and a lower pull roller 323 are provided on the inner side of the blower box 321. The upper pull roller 322 and the lower pull roller 323 are arranged alternately, and the lower pull roller 323 is located at the bottom of the upper pull roller 322. The blower box 321 can dry the leather by heating the internal air. The upper pull roller 322 can work with the lower pull roller 323 to provide sufficient tension to the leather, so that the leather is not easily deformed or loosened during drying.

[0034] A heating box 324 is also provided inside the air box 321. The heating boxes 324 are respectively located on the outside of the upper pull roller 322 and the lower pull roller 323. The heating boxes 324 are connected to each other through the pipe 325. The heating box 324 can heat the air around the leather on the upper pull roller 322 and the lower pull roller 323, so that the leather is dried more evenly.

[0035] An air pump 326 is fixedly installed on the top of the air box 321. The air pump 326 is connected to the heating box 324 through the pipe 325. The air pump 326 can deliver outside air to the heating box 324 through the pipe 325, thereby promoting air circulation in the air box 321 and assisting the heating box 324 in drying the leather.

[0036] The conveying component 4 includes a feeding roller 41, which is located in the coating chamber 2. The coating chamber 2 is also equipped with a partition 42. Auxiliary rollers 43 are provided on both sides of the feeding roller 41. The feeding roller 41 can feed the leather into the coating chamber 2 for soaking by rotating. The bottom of the partition 42 is provided with an opening to divide the coating chamber 2. The partition 42 can ensure that the two sides of the leather are horizontal when the leather enters and leaves the coating chamber 2. The auxiliary rollers 43 can pick up the soaked leather from the coating chamber 2 by rotating.

[0037] The conveying component 4 also includes a rotating roller 44, which is installed on the top of the base 1 and between the glue coating chamber 2 and the air box 321. A leveling roller 45 is also installed on the top of the rotating roller 44. The rotating roller 44 can provide power for the conveying of the leather by rotating and friction with the leather. The leveling roller 45 can straighten the leather after de-glueing, making it easier for the next drying step.

[0038] In operation, the rotation of the rotating roller 44 and the friction between it and the leather provide power for leather conveying, keeping the leather flat on both sides under the constraint of the auxiliary roller 43. The feeding roller 41 is fully immersed in the coating chamber 2, and the rotation of the auxiliary roller 43 retrieves the soaked leather from the coating chamber 2, thus ensuring the coating effect and conveying of the leather. The output shaft of the motor 316 rotates, causing the threaded ring 315 to rotate in the sleeve 313, which drives the threaded shaft 314 connected to the thread to change its length in the sleeve 313. This causes the baffle 311 to move toward the leather while maintaining an angle perpendicular to the machine base 1, so that the inclined glue removal plate 312... The contact distance with the leather varies to adapt to the glue removal requirements of leathers of different thicknesses. The scraped glue is collected in the filter box 318 through the drainage pipe 317 for filtration. The treated glue falls into the coating chamber 2 for reuse. The leather is dried in the air box 321 by heating the internal air. The upper pull roller 322 and the lower pull roller 323 provide sufficient tension to the leather so that it is not easily deformed or loosened during drying. The air pump 326 connected to the heating box 324 through the pipe 325 supplies outside air into the air box 321, thereby promoting airflow in the air box 321 and ensuring the drying effect of the leather.
