[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] like Figures 1 to 5 As shown, a three-roll mill for producing conductive paste in one embodiment of the present invention includes a three-roll mill body 11 and a plurality of rollers 12. The rollers 12 are rotatably connected to the three-roll mill body 11. The rollers 12 include a front roller, an intermediate roller and a rear roller. The conductive paste can be ground by the front roller, the intermediate roller and the rear roller.

[0025] A support frame 21 is provided on the main body 11 of the three-roll mill. The support frame 21 includes support legs on both sides of the main body 11 and a support arm in the middle located above the roller 12. A support rod 31 is provided between the support legs. A cleaning component 41 is provided on the support rod 31. The cleaning component 41 includes a scraper 42 that matches the roller 12.

[0026] Specifically, the scraper 42 is an arc-shaped plate that can fit against the surface of the roller 12. When the roller 12 rotates, the scraper 42 can scrape off the undried and dried slurry adhering to the surface of the roller 12, ensuring the cleanliness of the roller 12 surface. The cleaning personnel do not need to directly contact the rotating roller 12, increasing the safety of the cleaning personnel during cleaning.

[0027] The cleaning assembly 41 includes a receiving plate 43 fixedly connected to the scraper 42, and a shaft 45 fixedly connected to the receiving plate 43. A receiving cavity is formed between the receiving plate 43 and the scraper 42. The slurry scraped off by the scraper 42 can move along the scraper 42 into the receiving cavity, thereby cleaning and collecting the slurry and facilitating its subsequent recycling.

[0028] A cleaning plate 46 matching the cavity is installed inside the receiving cavity. A push rod 47 is fixedly connected to the cleaning plate 46, and a slide 44 is provided on the scraper 42. The slide 44 is inclined inward into the receiving cavity, so that the scraped slurry can fall into the receiving cavity along the slide 44 and the scraper 42. The cleaning plate 46 fits against the cavity wall and can move inside the receiving cavity, which facilitates the collection of slurry in the receiving cavity from one side to the other side, and then the slurry is scraped out from the cleaning assembly 41.

[0029] The three-roll mill body 11 has a movable groove 13 corresponding to the support leg, and a movable block 25 matching the movable groove 13 is fixedly connected to the bottom end of the support leg. The support frame 21 can move along the movable groove 13, thereby driving the cleaning component 41 to move and clean the front roller, the middle roller and the rear roller respectively.

[0030] The moving groove 13 is provided with several fixed grooves 26, and the moving block 25 is fixedly connected with a fixing plate 27 that matches the fixed groove 26. The fixing plate 27 can be snapped into the fixed groove 26 to fix the moving block 25 in the moving groove 13, increasing the stability of the support frame 21. At the same time, the distance between the fixed grooves 26 is the same as the distance between the rollers 12, which facilitates the positioning of the cleaning component 41.

[0031] Each support leg has a limiting groove 23 on the side near the roller 12, which matches the support rod 31. A compression spring 24 is fixedly connected between the bottom end face of the support rod 31 and the bottom wall of the limiting groove 23. A first support plate 32 and a second support plate 33 are fixedly connected between the support rod 31 and the cleaning assembly 41. The first support plate 32 is fixedly connected to the support rod 31, and the cleaning assembly 41 is fixedly connected to the second support plate 33.

[0032] Specifically, a threaded rod 22 is threadedly connected to the support arm, and a handle 28 is fixedly connected to the threaded rod 22. The handle 28 facilitates the rotation of the threaded rod 22, which can move up and down during rotation. When the threaded rod 22 moves downward, it abuts against the upper end face of the support rod 31, thereby driving the support rod 31 to move downward. The support rod 31, through the first support plate 32 and the second support plate 33, drives the cleaning assembly 41 to move downward, so that the scraper 42 is in contact with the surface of the roller 12. When the cleaning assembly 41 is not in use, the support rod 31 can be raised by the compression spring 24, so that the cleaning assembly 41 is located above the roller 12 for easy use.

[0033] The upper end face of the support rod 31 is provided with a support groove 37 that matches the threaded rod 22. The bottom end of the threaded rod 22 can be inserted into the support groove 37, which increases the stability of the support rod 31 when it moves.

[0034] The first support plate 32 has a buffer groove 35 that matches the second support plate 33. A buffer spring 36 is fixedly connected between the upper end face of the second support plate 33 and the bottom wall of the buffer groove 35. An insertion hole 34 is provided in the second support plate 33. The buffer spring 36 can buffer the second support plate 33 and the cleaning assembly 41, preventing the scraper 42 from hardly adhering to the surface of the roller 12 and causing wear.

[0035] The shaft 45 can be inserted into the socket 34 with an interference fit. On the one hand, this can increase the stability of the cleaning component 41, and on the other hand, it is convenient to remove the cleaning component 41 from the second support plate 33 to process the slurry inside the cleaning component 41.

[0036] When using, refer to Figures 1-5 As shown, the cleaning component 41 can clean and collect the slurry adhering to the surface of the roller 12. The support frame 21 and support rod 31 facilitate the movement of the cleaning component 41. When not in use, the cleaning component 41 is positioned above the roller 12 without interfering with the normal operation of the three-roll mill. When in use, the cleaning component 41 can be moved to fit against the surface of the roller 12, and it is convenient to clean the front roller, the middle roller and the rear roller separately.

[0037] Compared with the prior art, the three-roll mill for producing conductive paste of this utility model facilitates the cleaning of paste adhering to the rollers and increases the safety of cleaning personnel.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
