Therefore, it is widely used in the manufacturing and production of slurries such as paints, inks, pigments and plastics. Traditionally, the slurry needs to be poured manually, which leads to high labor intensity and low overall efficiency. Therefore, corresponding feeding equipment is needed to replace the manual feeding process.

[0003] After searching, the existing patent (Announcement No.: CN214916936U) discloses a three-roller grinding machine feeding device, which belongs to the field of feeding devices. It solves the problems of high labor intensity and low working efficiency of the existing three-roller grinding machine feeding. It includes a plate belt wheel, a fixed frame, a hopper, an H-shaped frame, a lifting connecting rod, a plate belt and a power mechanism. The power mechanism is arranged on the fixed frame, and the fixed frame is fixedly installed on the H-shaped frame. The H-shaped frame is respectively provided with a hopper track and a lifting connecting rod track in the vertical direction. One end of the hopper is slidably arranged in the hopper track, and the lifting connecting rod is slidably arranged in the lifting connecting rod track. The two ends of the power mechanism are respectively connected to the plate belt wheel, one end of the plate belt is wound on the plate belt wheel, and the other end is connected to the lifting connecting rod, and the lifting connecting rod is rotatably connected to the hopper. It is mainly used for feeding three-roller grinding machines.

[0029] The moving component 4 includes a fixed groove 406, which is opened at the upper end of the inner wall of the loading rack 3. A servo motor 401 is fixedly connected to the upper end of one side of the loading rack 3. The output end of the servo motor 401 extends to the inside of the fixed groove 406 and is fixedly connected to a threaded rod 403 through a coupling. The surface of the threaded rod 403 is threadedly connected to a threaded block 404. One end of the threaded block 404 is fixedly connected to the surface of the storage tank 8. By starting the servo motor 401 to drive the threaded rod 403 to rotate, the threaded block 404 slides and drives the storage tank 8 to slide, and then the slurry can be evenly discharged to the surface of the roller through the feeding pipe 5, so as to avoid local accumulation of the slurry on the surface of the roller and affect the grinding and dispersion effect of the three-roll grinder.

[0030] In this embodiment, a limiting groove 402 is opened at one end of the inner wall of the loading rack 3 away from the fixing groove 406. A limiting block 405 is slidably connected inside the limiting groove 402. One end of the limiting block 405 is fixedly connected to the surface of the storage tank 8.

[0033] Based on Embodiment 1, a preferred embodiment of the feeding device of the three-roll grinding machine provided by the present utility model is as Figures 1 to 5 shown: The adjusting assembly 6 includes an adjusting groove 607, which is opened on both sides of the bottom end of the loading rack 3. The top end of the fixing plate 7 is fixedly connected with an adjusting plate 604 extending into the adjusting groove 607. A plurality of positioning holes 603 are equidistantly opened on one side of the adjusting plate 604. The lower ends on both sides of the loading rack 3 are fixedly connected with adjusting boxes 602. One side of the adjusting box 602 is movably connected with a pulling rack 601 extending into the adjusting box 602. One side of the pulling rack 601 is fixedly connected with a positioning rack 608 extending into the adjusting groove 607. A return spring 609 is wound around the surface of the pulling rack 601 on one side of the positioning rack 608. One end of the return spring 609 is fixedly connected to the inner wall of the adjusting box 602. By sliding the adjusting plate 604 inside the adjusting groove 607 and using the elastic force of the return spring 609, the positioning rack 608 can slide and be stuck into a suitable positioning hole 603, realizing the limit fixation after the sliding of the adjusting plate 604, and further changing the distance between the bottom end of the feeding pipe 5 and the surface of the roller, ensuring the optimal discharging height of the slurry.

Both ends on one side of the positioning rack 608 are fixedly connected with sliders 606 that are slidably matched with the inside of the sliding groove 605. By sliding the sliders 606 inside the sliding groove 605, the back-and-forth sliding of the positioning rack 608 becomes smoother.

[0035] In this embodiment, a sliding structure is formed between the adjusting plate 604 and the inside of the adjusting groove 607. The shapes of the top views of the adjusting plate 604 and the adjusting groove 607 are in the shape of a Chinese character '丰' (feng). By sliding the adjusting plate 604 in the shape of '丰' inside the adjusting groove 607, the smoothness of their sliding is improved, facilitating the adjustment of the overall height of the loading rack 3.

[0036] In this embodiment, a snap-fit ​​structure is formed between one side of the positioning frame 608 and the inside of the positioning hole 603. The shape of the positioning frame 608 in the top view is E-shaped. The E-shaped positioning frame 608 is snap-fitted with the inside of the positioning hole 603 to achieve limited fixation after the adjustment plate 604 slides.

[0037] In addition, the inner bottom wall of the storage tank 8 is fixedly connected with a guide platform 9, and the guide platform 9 is funnel-shaped. The funnel-shaped guide platform 9 allows the slurry inside the storage tank 8 to be discharged more smoothly and thoroughly from the feeding pipe 5.

[0038] The working principle and use process of the utility model are as follows: first, the pull frame 601 is pulled to drive the positioning frame 608 to slide and compress the reset spring 609 until it is completely separated from the inside of the positioning hole 603, and then the fixed plate 7 is pulled hard to drive the adjustment plate 604 to slide to a suitable height, and then the pull frame 601 is released, and the elastic force of the reset spring 609 is used to make the positioning frame 608 slide and clamp to the inside of the suitable positioning hole 603, so as to achieve the limited fixation of the adjustment plate 604 after sliding, and then the overall height of the feeding frame 3, the adjustment plate 604 and the fixed plate 7 can be changed, so that the distance between the bottom end of the feeding pipe 5 and the roller surface changes, so as to ensure the optimal discharge height of the slurry, and avoid the feeding pipe 5 from being too high to cause the slurry to fall and splash or too low to cause poor discharge, so as to meet the feeding requirements of different three-roll grinders and improve its applicability;

[0039] Afterwards, the fixing plate 7 is installed and fixed at the appropriate position of the three-roll grinder by external bolts, and then an appropriate amount of slurry is added into the storage tank 8 through the feed hopper 2, and then the feeding pipe 5 is opened to discharge the slurry, and the feeding action of the three-roll grinder is performed. At this time, the pneumatic telescopic rod 1 is started to drive the push plate 10 to slide down inside the storage tank 8, and the slurry inside the storage tank 8 is pressurized so that it can be discharged more smoothly and evenly from the feeding pipe 5. At the same time, the servo motor 401 is started to drive the threaded rod 403 to rotate, and the threaded rod 403 and the threaded block 404 are matched by the threads, so that the threaded block 404 slides and drives the storage tank 8 to slide, and the limit block 405 slides inside the limit groove 402, so that the storage tank 8 slides smoothly and drives the feeding pipe 5 to slide left and right above the roller, so as to facilitate the uniform feeding of the slurry on the roller surface, and avoid the local accumulation of slurry on the roller surface affecting the grinding and dispersion effect of the three-roll grinder.
