Description

Technical Field

[0001] This utility model relates to the field of leather coating technology, and in particular to a device for adjusting the thickness of wet-process base coating in leather production. Background Technology

[0002] There is an urgent need in the industry for a new type of leather wet-process base coating thickness adjustment device that can provide high-precision thickness adjustment, ensure operational stability, and facilitate cleaning and maintenance. Although the existing parallel scraper still has some practicality in certain application scenarios, its limitations are obvious when facing modern leather manufacturing processes that require high precision and flexibility. Moreover, in frequent use, the parallel scraper is prone to bending or deformation, which will also affect the uniformity of the coating.

[0003] Therefore, in order to address the above problems, a device for adjusting the thickness of wet-process base coating in leather production is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices, such as the scraper being prone to bending or deformation, which affects the uniformity of the coating and the inability to be highly precise and flexibly adapted, this utility model provides a wet-coating thickness adjustment device for leather making.

[0005] The technical implementation scheme of this utility model is as follows: a leather wet-process base coating thickness adjustment device, including a mounting plate, the mounting plate having a triangular structure, a first hydraulic cylinder connected to the left end of the mounting plate, the first hydraulic cylinder being oriented downwards, a first guide member connected to the rear end of the mounting plate, a first scraper slidably connected to the lower side of the mounting plate, the first scraper consisting of two pieces, the telescopic end of the first hydraulic cylinder being connected to the left first scraper, the first guide member being slidably connected to the rear first scraper, a second scraper being connected between the right sides of the first scraper, the second scraper having a V-shaped structure, a second guide member connected to the front right side of the mounting plate, the second guide member being slidably connected to the second scraper, a second hydraulic cylinder connected to the right side of the mounting plate, the telescopic end of the second hydraulic cylinder being oriented downwards, and the telescopic end of the second hydraulic cylinder being connected to the second scraper.

[0006] In a preferred embodiment of this utility model, an infusion tube is also included. An infusion tube is connected to the front right part of the mounting plate. The infusion tube has a water inlet and is also V-shaped. A mounting base is connected to the infusion tube. There are 15 mounting bases. The mounting bases are connected to the mounting plate. A nozzle is connected to the lower end of each infusion tube. The nozzles are all located inside the first scraper and the second scraper and are used to rinse the inside of the first scraper and the second scraper.

[0007] In a preferred embodiment of this utility model, ribs are provided on the outer side of the first scraper to improve stability during operation.

[0008] In a preferred embodiment of this utility model, the connection between the first scraper and the second scraper is an arc-shaped structure, which can help reduce paint accumulation during the scraping process.

[0009] In a preferred embodiment of this invention, the second scraper has an inclined structure, which allows for more precise adjustment of the coating thickness.

[0010] In a preferred embodiment of this invention, the nozzle has a conical structure, which helps to concentrate the spray for cleaning.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention ensures the stability and accuracy of the first and second scrapers during their up-and-down movement by using a diagonal installation method of the first and second hydraulic cylinders and the first and second guide members. The V-shaped structure design of the second scraper can better resist bending and deformation under frequent use, and can also more precisely adjust the thickness of the coating. In the edge area, it helps to reduce edge buildup, thereby improving the overall quality and aesthetics of the coating. Attached Figure Description

[0017] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0018] A device for adjusting the thickness of wet Fabry coating in leather production, such as Figures 1-3 As shown, the system includes a mounting plate 4, which has a triangular structure. A first hydraulic cylinder 5 is connected to the left end of the mounting plate 4, and the first hydraulic cylinder 5 is oriented downwards. A first guide member 6 is connected to the rear end of the mounting plate 4. A first scraper 1 is slidably connected to the lower side of the mounting plate 4. The first scraper 1 consists of two pieces, each with ribs on its outer side to improve stability during operation. The telescopic end of the first hydraulic cylinder 5 is connected to the left first scraper 1, and the first guide member 6 is slidably connected to the rear first scraper 1. The connection between the first scraper 1 and the second scraper 2 has an arc-shaped structure, which helps reduce paint accumulation during the scraping process. A second scraper 2 is connected to the right side of the first scraper 1. The second scraper 2 has a V-shaped structure and a sloping surface structure 3, allowing for more precise adjustment. The coating thickness is determined by the fact that the mounting plate 4 has a second guide 7 connected to its right front part, which is slidably connected to the second scraper 2. The mounting plate 4 also has a second hydraulic cylinder 8 connected to its right side, with the telescopic end of the second hydraulic cylinder 8 facing downwards. The telescopic end of the second hydraulic cylinder 8 is connected to the second scraper 2. The mounting plate 4 also includes an infusion pipe 9, which has an inlet on its front right side. The infusion pipe 9 is also a V-shaped structure. The infusion pipe 9 is connected to a mounting base 10, which has 15 mounting bases. The mounting base 10 is connected to the mounting plate. The lower end of each infusion pipe 9 is connected to a nozzle 11, which has a conical structure to facilitate concentrated spray cleaning. The nozzles 11 are all located inside the first scraper 1 and the second scraper 2 and are used to rinse the inside of the first scraper 1 and the second scraper 2.

[0019] It should be noted that this device can be used to assist in adjusting the thickness of the wet-coating on leather. This device employs a V-shaped scraper design, which helps to better control the coating thickness at the edges, reducing edge buildup or insufficient coating. Furthermore, in situations requiring frequent scraping, the V-shaped design better resists the risk of bending and deformation. First, adjust the V-shaped opening of the device to the corresponding leather. Then, place the device in the desired position. Next, activate the corresponding device. Before the conveyor shaft transports the corresponding leather to the first scraper 1, activate the first hydraulic cylinder 5. At this time, the telescopic end of the first hydraulic cylinder 5 moves downward, driving the left first scraper 1 downward, causing the rear first scraper 1 to move downward along the first guide member 6. The first hydraulic cylinder 5 and the first guide member 6 cooperate to ensure the stability of the first scraper 1 during its up-and-down movement, thereby moving the second scraper 2 downward until the first scraper 1 is positioned on the leather. At both ends, the second scraper 2 contacts the leather coating. The coating thickness is adjusted as needed, and excess coating is scraped off. At this time, the leather moves inward according to the second scraper 2, and the second hydraulic cylinder 8 is activated. The extension end of the second hydraulic cylinder 8 drives the second scraper 2 to move downward along the second guide member 7. At this time, the inclined structure allows the second scraper 2 to be finely adjusted, thereby achieving the purpose of accurately adjusting the coating thickness. The cooperation of the second hydraulic cylinder 8 and the second guide member 7 further ensures the stability and accuracy of the second scraper 2 during the working process. After the scraping work is completed, coating material will remain on the scraper. At this time, it is necessary to clean the scraper to maintain the continuity of the coating process and the coating quality of this device. First, connect the water inlet of the infusion pipe 9 to the water pipe, then open the water valve to let the clean water pass through the infusion pipe 9 and guide it to the nozzle 11. Then, using the conical structure of the nozzle 11, the water flow is concentrated and sprayed onto the inner side of the first scraper 1 and the second scraper 2 until the cleaning is completed.

Therefore, the scope of this invention should be limited only by the appended claims.
