[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] See also Figure 1-3 The present application provides a technical solution: a leather pretreatment device for TPR upper bonding, comprising a base support 8, on which a leather unloading group and a leather receiving group are arranged, a vertical mounting seat 12 is arranged in the middle of the base support 8, and two groups of scraper groups for cleaning the leather surface and a cleaning group for cleaning the leather are arranged on the vertical mounting seat 12.

[0017] A vertical mounting seat 12 is provided in the middle part of the base support 8, on which a scraper group and a cleaning group are arranged; the scraper group is mainly used for physically cleaning the leather surface, and the cleaning group is responsible for cleaning the leather, providing high-quality raw material guarantee for subsequent TPR upper bonding.

[0018] The scraper group is mainly composed of a side frame support plate 5, a telescopic cylinder 11, a scraper support 16 and a scraper 17. The side frame support plate 5 is connected to the vertical mounting seat 12 through fasteners. The telescopic cylinders 11 are symmetrically arranged on both sides of the side frame support plate 5. The telescopic ends of the telescopic cylinders 11 are connected to the scraper supports 16. The scrapers 17 are arranged between the scraper supports 16.

[0019] The scraper group effectively scrapes and cleans the leather surface to ensure that the leather surface is clean and smooth, providing convenience for subsequent bonding.

[0020] The side frame support plate 5 is the main supporting structure of the scraper group. The side frame support plate 5 is symmetrically provided with a telescopic cylinder 11 to ensure the stability of the scraper group during operation.

[0021] The telescopic cylinder 11 adjusts its telescopic length as needed, thereby changing the contact force between the scraper 17 and the leather; when the telescopic cylinder 11 is in motion, its telescopic end will push or pull the scraper support 16, so that the scraper support 16 can reciprocate within a certain range.

[0022] The scraper 17 is usually made of a material with moderate hardness, wear resistance and durability. It can effectively scrape off dust, grease and other impurities on the leather surface without damaging the leather. It can achieve refined and dynamic cleaning of the leather surface, greatly improve the efficiency and quality of leather pretreatment, and provide a high-quality raw material foundation for subsequent TPR upper bonding.

[0023] The cleaning group includes a cleaning seat mounting plate 18, a nozzle mounting seat 4 and a spray atomizing head 14. The cleaning seat mounting plate 18 is connected to the vertical mounting seat 12 through fasteners. A spray atomizing head 14 is arranged on one side of the cleaning seat mounting plate 18. The spray atomizing head 14 is arranged corresponding to the nozzle mounting seat 4 arranged on one side of the cleaning seat mounting plate 18.

[0024] The cleaning group performs a deeper cleaning on the leather that has been initially cleaned by the scraper group.

[0025] The cleaning seat mounting plate 18 is firmly connected to the vertical mounting seat 12 by fasteners, providing a stable mounting platform for the cleaning group; the spray atomization head 14 has the function of converting the liquid medium (such as cleaning agent) into fine and uniform droplets, which can fully cover the leather surface over a large area, achieving efficient and thorough cleaning effect.

[0026] The spray head mounting base 4 is used to fix and position the spray atomizing head 14 to ensure that it maintains an accurate direction during operation and facilitates maintenance and replacement.

[0027] After the cleaning liquid in the cleaning water tank 13 is pressurized by a pressure pump, it is transported to the nozzle mounting seat 4 through a pipeline, and then sprayed out by the spray atomizer head 14 to form a dense and uniform atomized water flow, which comprehensively and carefully rinses the leather, effectively removing the tiny particles and stains remaining on the leather surface, and improving the cleanliness of the leather surface and the subsequent bonding performance.

[0028] Furthermore, the leather unloading group is located at the lower protruding end of the base support 8, and the leather unloading group includes a first driving motor 6, a unloading shaft 9 and an axial side support plate 10. The axial side support plate 10 is located on the inner wall of the base support 8. The first driving motor 6 is connected to the axial side support plate 10 through fasteners. The output end of the first driving motor 6 is connected to the unloading shaft 9, and the other end of the unloading shaft 9 is connected to the axial side support plate 10.

[0029] The leather unloading group is designed to achieve continuous and stable supply of leather materials and facilitate the loading and releasing of leather rolls.

[0030] The first drive motor 6 is started, driving the unloading shaft 9 to rotate synchronously; the leather coil is sleeved on the unloading shaft 9, and as the motor is driven, the unloading shaft 9 rotates, so that the leather can be evenly and continuously loosened from the coil as needed and conveyed forward to enter the subsequent cleaning and washing process.

[0031] Furthermore, a supporting side frame 15 is provided on one side of the vertical mounting seat 12, and a leather collecting group is provided in the supporting side frame 15, and the leather collecting group includes an axial side support plate 10, a collecting reel 2 and a second driving motor 3, the second driving motor 3 is connected to the axial side support plate 10 through a fastener, the output end of the second driving motor 3 is connected to the collecting reel 2, and the other end of the collecting reel 2 is transferred to the axial side support plate 10.

[0032] When the second drive motor 3 is started, it can drive the receiving reel 2 to rotate. After the leather is pre-treated, it will be guided to the receiving reel 2 and gradually wound up under the drive of the second drive motor 3. The cleaned and washed leather material is wound up and stored in an orderly and compact manner.

[0033] Furthermore, an auxiliary rotating shaft 19 for assisting leather winding is provided between the vertical mounting seats 12 .

[0034] In the leather pretreatment device, due to the weight of the leather itself and the change in stretching during the treatment process, the tension of the leather during the transmission process may be uneven, affecting the quality of the final leather winding. To this end, the auxiliary shaft 19 can assist in adjusting and balancing the tension of the leather during the transmission process, so that the leather always remains straight and uniform, avoiding wrinkles or sagging.

[0035] Furthermore, a cleaning water tank 13 is provided on one side of the base support 8 , and an output end of the cleaning water tank 13 is provided to be connected to an input end of a pressure pump, and the output end of the pressure pump is connected to an input end of the nozzle mounting seat 4 .

[0036] Furthermore, a rotating wheel set 7 is provided on the lower surface of the base support 8 .

[0037] When in use: first, the leather coil to be processed is mounted on the discharge shaft 9 in the leather discharge group, and the power generated by the first drive motor 6 is transmitted to the discharge shaft 9 by starting the first drive motor 6, so that the leather can be released from the coil evenly and continuously, and is conveyed to the pre-treatment area along the device. In this process, the leather first passes through the scraper group, and the telescopic cylinder 11 on the side frame support plate 5 can flexibly adjust the contact force between the scraper 17 and the leather according to the thickness and surface condition of the leather. The scraper 17 performs fine scraping and cleaning on both sides of the leather, effectively removing impurities and excess substances attached to the surface.

[0038] Then, the leather continues to move forward to the cleaning group. Driven by the pressure pump, the spray atomizer head 14 on the cleaning seat mounting plate 18 atomizes the cleaning liquid in the cleaning water tank 13 into a fine mist, which is evenly sprayed on the leather surface to deeply clean the leather. The spray head mounting seat 4 ensures the stable pointing of the atomizer head, making the cleaning more accurate and thorough.

[0039] After being cleaned and washed, the leather flows along the device to the leather receiving group. The second drive motor 3 is started to drive the receiving reel 2 to rotate, and the processed leather is wound on the receiving reel 2 in an orderly manner.

[0040] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
