Description

Technical Field

[0001] This utility model relates to the field of powder coating processing and grinding technology, specifically a material grinding device. Background Technology

[0002] Powder coating is a new type of solid powder coating. It is made from solid resin, pigments, fillers and additives through a specific process. Unlike traditional solvent-based coatings and water-based coatings, powder coating does not use solvents or water as a dispersion medium. Instead, it uses air as the dispersion medium. It has advantages such as no solvent pollution, 100% film formation, low energy consumption, high utilization rate, and convenient transportation and storage. It is an environmentally friendly, efficient and economical type of coating.

[0003] According to patent number 201922136431.1 published on the China Patent Network, this utility model discloses a coating grinding device, relating to the field of coating grinding. It includes a base, a grinding device, and a protective shell. The grinding device includes a vertical fixed frame, a lead screw, a horizontal lifting platform, grinding components, and a driving component. The grinding component includes a vertical support frame, a rotating frame, a grinding cylinder, a grinding shaft, and a grinding rod. The driving component includes a cylindrical transmission frame, a drive motor, a transmission shaft, a drive pulley, and a drive gear. This device can screen the grinding coating particles, resulting in a smoother and more refined coating. The particle size of the material is guaranteed, enabling efficient grinding of coating particles and greatly improving grinding efficiency and effect. However, the grinding equipment still has certain limitations in its design. Specifically, the feeding method generally adopts a direct pouring method, that is, the user needs to put the raw material to be ground directly into the feed port of the equipment. Although this design is intuitive to operate, it lacks an effective feeding amount control mechanism. As a result, in actual application, if the user underestimates the feeding amount or is slightly careless in operation, excess raw material will quickly accumulate in the feeding area, which will cause material jamming and reduce the practicality of the grinding equipment.

[0004] Therefore, the grinding equipment needs to be improved to prevent material jamming when users feed material into the inlet. Utility Model Content

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.

[0022] like Figures 1 to 4 As shown, the present invention provides a material grinding device, including a grinder 1, with a feed inlet 2 fixedly connected to the top of the grinder 1;

[0023] A first rotating rod 3 is provided at the bottom of the feed inlet 2. The bottom of the first rotating rod 3 extends into the interior of the grinder 1 and is movably connected to the inner wall of the grinder 1 through a bearing. The top of the first rotating rod 3 extends into the interior of the feed inlet 2 and is fixedly connected to a connecting rod 4. A rotating block 5 is fixedly connected to the surface of the connecting rod 4. Multiple pusher plates 6 are fixedly connected to the surface of the rotating block 5. A first rotating wheel 7 is fixedly connected to the surface of the first rotating rod 3. A second rotating wheel 8 is provided at the rear side of the top of the grinder 1. The first rotating wheel 7 and the second rotating wheel 8 are connected by a belt. A second rotating rod 9 is fixedly connected inside the second rotating wheel 8. A motor 10 is provided at the top of the second rotating rod 9. The output end of the motor 10 is fixedly connected to the top of the second rotating rod 9. The bottom of the second rotating rod 9 extends into the interior of the grinder 1 and is movably connected to the inner wall of the grinder 1 through a bearing. A connecting plate 11 is fixedly connected to the rear side of the motor 10. The bottom of the connecting plate 11 is fixedly connected to the top of the grinder 1.

[0024] refer to Figure 4 A screen 12 is provided at the top of the feed inlet 2. A limiting block 13 is fixedly connected inside the screen 12. The bottom of the limiting block 13 extends into the interior of the rotating block 5 and is slidably connected to the inner wall of the rotating block 5. Push plates 14 are slidably connected to both sides of the inner wall of the limiting block 13. A locking block 15 is fixedly connected to the outer side of the push plate 14. The locking block 15 passes through the limiting block 13 and extends into the interior of the rotating block 5. A connecting block 16 is fixedly connected to the top of the push plate 14. The top of the connecting block 16 passes through the top of the limiting block 13 and is slidably connected to the inner wall of the limiting block 13. Two springers 17 are fixedly connected to the opposite side of the push plate 14.

[0025] As a technical optimization of this utility model, by setting up a screen 12, a limiting block 13, a push plate 14, a locking block 15, a connecting block 16 and a spring rebounder 17, the raw materials can be screened, avoiding the phenomenon that large raw materials are prone to blockage after falling into the feed inlet 2.

[0026] refer to Figure 4 The limiting block 13 has two guide rods 18 fixedly connected horizontally inside. The guide rods 18 pass through the push plate 14 and are slidably connected to the push plate 14.

[0027] As a technical optimization of this utility model, by setting the guide rod 18, the push plate 14 can be guided to prevent the push plate 14 from tilting and getting stuck when moving.

[0028] refer to Figure 4 A pull plate 19 is fixedly connected to the top of the connecting block 16, and the bottom of the pull plate 19 is slidably connected to the top of the limiting block 13.

[0029] As a technical optimization of this utility model, by setting the pull plate 19, it is easier for the user to pull the connecting block 16 and the push plate 14, thereby improving the user's comfort.

[0030] refer to Figure 4 A friction pad 20 is fixedly connected to the outer side of the locking block 15, and the surface of the friction pad 20 is in contact with the inner wall of the rotating block 5.

[0031] As a technical optimization of this utility model, by setting the friction pad 20, the contact between the card block 15 and the inner wall of the rotating block 5 can be made tighter, increasing the contact area between the card block 15 and the rotating block 5.

[0032] refer to Figure 3 A guide slope 21 is provided on the front side of the bottom of the inner wall of the feed inlet 2. The guide slope 21 is used in conjunction with the pusher plate 6.

[0033] As a technical optimization of this utility model, by setting the guide slope 21, the raw materials can be guided, which enhances the auxiliary feeding function of the pusher plate 6.

[0034] The working principle and usage process of this utility model are as follows: In use, firstly, the limiting block 13 is inserted into the interior of the rotating block 5, so that the screen 12 is placed on top of the feed inlet 2. The spring force of the spring spring 17 drives the push plate 14 and the locking block 15 to move inward, so that the locking block 15 is locked into the interior of the rotating block 5 to limit the screen 12. Then, the motor 10 is started. The output end of the motor 10 drives the second rotating rod 9 to rotate. The second rotating rod 9 drives the second rotating wheel 8 to rotate. The second rotating wheel 8 drives the first rotating wheel 7 to rotate through the belt. The first rotating wheel 7 drives the first rotating rod 3 to rotate. The first rotating rod 3 drives the connecting rod 4 and the rotating block 5 to rotate. The rotating block 5 drives the push plate 6 and the screen 12 to rotate. The user puts the raw material into the interior of the screen 12. The raw material of the appropriate size falls into the interior of the feed inlet 2. The rotating push plate 6 guides the raw material through the guide slope 21 into the interior of the grinder 1.

[0035] In summary, this material grinding device, by setting up a rotating block 5, a pusher plate 6, and a guide slope 21, can assist in the feeding of raw materials, avoiding the phenomenon of material jamming when too much material is placed. By setting up a motor 10, a second rotating rod 9, a second rotating wheel 8, a first rotating wheel 7, a first rotating rod 3, and a connecting rod 4, it can drive the rotating block 5 and the pusher plate 6 to rotate. By setting up a screen 12, a limiting block 13, a pusher plate 14, and a locking block 15, the screen 12 can be installed and used. This avoids the phenomenon of excessively large raw materials blocking the feed inlet 2, thus possessing the advantage of assisted feeding. It solves the certain limitations in the design of the grinding equipment, specifically, its feeding method generally adopts a direct pouring type, that is, the user needs to put the raw material to be ground directly into the feed inlet of the equipment. Although this design is intuitive to operate, it lacks an effective feeding quantity control mechanism. As a result, in actual application, if the user underestimates the feeding quantity or is slightly careless in operation, excessive raw materials will quickly accumulate in the feeding area, leading to material jamming problems and reducing the practicality of the grinding equipment.
