[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, the present invention provides a powder coating tableting device, including a housing 1, a hopper 2 fixedly connected to the top of the housing 1, the discharge port of the hopper 2 extending into the interior of the housing 1, a heater 3 fixedly connected to the inner wall of the hopper 2, a transmission 4 fixedly connected to the back of the housing 1, the output end of the transmission 4 extending into the interior of the housing 1 and fixedly connected to a tableting roller 5 and an auxiliary roller 6 respectively, the tableting roller 5 being located to the left of the auxiliary roller 6, and a motor 7 fixedly connected to the front of the housing 1, the output end of the motor 7 extending into the interior of the housing 1 and fixedly connected to the front of the tableting roller 5;

[0026] The cleaning mechanism includes a self-cleaning membrane 8 fixedly connected to the surface of the auxiliary roller 6. A movable plate 9 located at the bottom of the tableting roller 5 is hinged to the left side inside the outer shell 1. A rubber scraper 10 is movably connected to the top of the movable plate 9. The top of the rubber scraper 10 is movably connected to the bottom of the tableting roller 5. A compression spring 11 is fixedly connected to the bottom of the movable plate 9. The bottom of the compression spring 11 is fixedly connected to the inner wall of the outer shell 1. An adjustment mechanism is provided inside the hopper 2. A sealing mechanism is provided inside the outer shell 1.

[0027] refer to Figure 3 The adjustment mechanism includes a feeding roller 12 that is movably connected inside the hopper 2 and located at the bottom of the heater 3. A motor 13 is fixedly connected to the front of the hopper 2. The output end of the motor 13 extends into the hopper 2 and is fixedly connected to the front of the feeding roller 12.

[0028] As a technical optimization of this utility model, by setting the feeding roller 12 and the motor 13, the amount of coating material conveyed from the hopper 2 to the outer shell 1 is controlled, so as to avoid conveying too much coating material into the outer shell 1 at one time, which would cause the tableting device to malfunction.

[0029] refer to Figure 6 The sealing mechanism includes an auxiliary frame 14 that is fixedly connected to the front and back sides of the housing 1. A sealing rubber 15 is fixedly connected to the inner side of the auxiliary frame 14. The inner side of the sealing rubber 15 is sealed to the surfaces of the pressing roller 5 and the self-cleaning membrane 8 respectively. The auxiliary mechanism is provided inside the housing 1.

[0030] As a technical optimization of this utility model, by setting an auxiliary frame 14 and sealing rubber 15, the gap between the outer shell 1 and the tableting roller 5 and the auxiliary roller 6 is sealed to prevent the coating from leaking from the gap between the outer shell 1 and the tableting roller 5 and the auxiliary roller 6, thereby affecting the production quality of the tableting device.

[0031] refer to Figure 6 The auxiliary mechanism includes a baffle 16 fixedly connected inside the housing 1 and located on top of the tableting roller 5. The surface of the baffle 16 is fixedly connected to the surface of the auxiliary frame 14. A sealing strip 17 is fixedly connected to the bottom of the baffle 16. The bottom of the sealing strip 17 is sealed to the surfaces of the tableting roller 5 and the self-cleaning membrane 8 respectively.

[0032] As a technical optimization of this utility model, by setting baffle 16 and sealing strip 17, when the hopper 2 delivers too much paint into the outer shell 1 at one time due to a malfunction, the paint in the outer shell 1 is blocked and limited to prevent the paint from scattering inside the outer shell 1.

[0033] refer to Figure 7 The bottom of the rubber scraper 10 is provided with a connecting groove 18, and the top of the movable plate 9 is fixedly connected with a locking block 19, the top of the locking block 19 extending into the interior of the connecting groove 18.

[0034] As a technical optimization of this utility model, by setting the connecting groove 18 and the locking block 19, the rubber scraper 10 and the movable plate 9 can be quickly disassembled and assembled, which makes it convenient for workers to replace the rubber scraper 10 when it is damaged.

[0035] refer to Figure 5 The bottom of the inner shell 1 and the bottom of the movable plate 9 are both provided with annular grooves 20 located outside the compression spring 11. An elastic cloth 21 is sleeved on the outside of the compression spring 11, and the top and bottom of the elastic cloth 21 extend into the interior of the annular groove 20.

[0036] As a technical optimization of this utility model, the compression spring 11 is protected by setting an annular groove 20 and elastic cloth 21 to prevent debris from adhering to the surface of the compression spring 11 and thus affecting the normal operation of the compression spring 11.

[0037] The working principle and usage process of this utility model are as follows: During use, the paint is conveyed into the interior of the outer shell 1 through the hopper 2. At this time, the motor 7 is started. The motor 7 drives the pressing roller 5 and the auxiliary roller 6 to rotate through the output end and the transmission device 4. The rotation of the pressing roller 5 and the auxiliary roller 6 is used to press the paint. Since the surface of the auxiliary roller 6 has a self-cleaning film 8, the pressed paint will not adhere to the auxiliary roller 6. The movable plate 9 will be pushed by the pressure spring 11 to drive the rubber scraper 10 to move upward, so that the rubber scraper 10 contacts the pressing roller 5. The rubber scraper 10, in conjunction with the rotation of the pressing roller 5, scrapes off the paint adhering to the pressing roller 5. The pressed paint will be discharged from the pressing device through the discharge port of the outer shell 1.

[0038] In summary, this powder coating tableting device, by setting a self-cleaning membrane 8, avoids the pressed coating from simultaneously adhering to the tableting roller 5 and the auxiliary roller 6, which would cause the pressed coating to crack. Furthermore, the pressure spring 11, the movable plate 9, and the rubber scraper 10 are used to separate the coating from the tableting roller 5, preventing the coating from adhering to the tableting roller 5 and affecting the pressing of subsequent coatings by the tableting roller 5, thereby improving the practicality of the tableting device.
