Description

Technical Field

[0001] This utility model relates to the technical field of three-roll mills, specifically a material adjustment mechanism for a three-roll mill. Background Technology

[0002] A three-roll mill is a device that uses three horizontal and counter-rotating rollers to generate strong shearing, extrusion, and grinding effects. Its core purpose is to refine materials with high viscosity and high fineness requirements (such as coatings, inks, ointments, ceramic slurries, etc.) to the micron level, eliminate particle agglomeration, and achieve uniform mixing of components. It is widely used in chemical, pharmaceutical, food, and new materials fields and is one of the key pieces of equipment for the preparation of highly dispersible materials.

[0003] The existing Chinese patent announcement number CN220990985U, entitled "A Material Adjustment Mechanism for a Three-Roller Mill," explicitly states in its abstract that "This utility model discloses a material adjustment mechanism for a three-roller mill, relating to the field of material control technology. Specifically, it includes a three-roller mill body, with two motor connectors fixedly connected to one side of the upper surface of the three-roller mill body, and a defective product inlet block fixedly connected to the other side of the upper surface of the three-roller mill body. This material adjustment mechanism for the three-roller mill, through the arrangement of the main shaft, oscillating block, and adjusting handle, ensures the screening efficiency of the device, thereby ensuring uniformity of the incoming material. It allows for adjustment of the filter hole size, resulting in a uniform particle size distribution of the ground material. This solves the problem that most three-roller mills lack a material screening structure, leading to inconsistent incoming material, reduced production efficiency, and difficulty in precisely controlling particle size, which can result in uneven particle size distribution and compromised production quality."

[0004] However, in this technology, the adjustment block is completely embedded inside the oscillating block, and both have dense filter holes. Once the filter holes become clogged, due to the lack of a dedicated disassembly and cleaning structure, the oscillating block needs to be disassembled. Moreover, the disassembly process requires disassembling multiple related components such as the spindle and the limit sleeve in sequence, which is cumbersome and time-consuming, significantly increasing the downtime maintenance cost and time cost of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a material adjustment mechanism for a three-roll mill to solve the problem of inconvenient cleaning mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A material adjustment mechanism for a three-roll mill includes a mill body, a hopper, and a hollow semi-cylindrical screen. A U-shaped groove is provided on one side of the top of the mill body; a disassembly assembly is provided on the top of the U-shaped groove on one side. The assembly and disassembly assembly includes a slide groove, inside which a sliding block is slidably arranged, and inside the sliding block a second internal hexagonal column is rotatably arranged, and hexagonal rods are arranged on both sides of the screen.

[0007] In a preferred embodiment of this utility model, rectangular blocks are provided on both sides of the hopper, and the rectangular blocks are assembled and disassembled in the U-shaped groove.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please refer to Figures 1-4This utility model discloses a material adjustment mechanism for a three-roll mill, including a mill body 1, which is a three-roll mill and directly adopts the three-roll mill from the background technology patent, a hopper 11, a U-shaped groove 12 on one side of the top of the mill body 1, and rectangular blocks 13 on both sides of the hopper 11. The rectangular blocks 13 are installed and removed in the U-shaped groove 12. The hopper 11 is wider at the top and narrower at the bottom, and it runs through the mill from top to bottom. The hopper 11 is installed by installing the rectangular blocks 13 on both sides in the U-shaped groove 12. Material is added to the hopper 11 and enters the three-roll mill through the hopper 11. Conversely, the hopper 11 can be directly disassembled for easy cleaning. The U-shaped groove 12 and the structure at the top of the U-shaped groove 12 are fixedly installed on the top of the mill body 1 by welding or other existing methods.

[0021] The hollow semi-cylindrical screen 2 has a disassembly assembly on the top of a U-shaped groove 12 on one side. This assembly includes a sliding groove 3, inside which a sliding block 31 is slidably mounted. A second internal hexagonal column 32 is rotatably mounted inside the sliding block 31. Hexagonal rods 21 are mounted on both sides of the screen 2. A mounting frame 22 is mounted on the top of the U-shaped groove 12 on the other side. A first internal hexagonal column 23 is rotatably mounted inside the mounting frame 22. The hexagonal rods 21 on both sides are disassembled and assembled within the first internal hexagonal column 23 and the second internal hexagonal column 32, respectively. A motor 24, a servo motor (model SGMAH-04AAA41), is mounted on the outside of the mounting frame 22. A PLC controller (model FX3U-16MR / ES-A) is mounted on one side of the grinding machine body 1 to control the motor 24. This controller is pre-tested and configured for use by those skilled in the art. Using conventional techniques, the output of motor 24 is connected to the first internal hexagonal column 23. By installing the hexagonal rods 21 on both sides into the internal hexagonal columns, the screen 2 is installed. At this time, the screen 2 is directly above the hopper 11. When feeding, the material is first poured into the screen 2, screened by the screen 2, and then enters the hopper 11. The motor 24 drives the internal hexagonal column to rotate back and forth, thereby driving the screen 2 to rotate back and forth. The rotation method is to rotate 30°-45° to one side, then rotate back to the initial angle, and then rotate 30°-45° to the other side (this angle range can balance screening efficiency and material stability; if the angle is too small, the material will easily accumulate; if the angle is too large, the material will easily spill from the edge of the screen). This process is repeated. The reciprocating rotation of the screen 2 can effectively ensure the material falls and improve screening efficiency.

[0022] The top of the slide groove 3 is provided with a mounting groove 33, and a fixing block 4 is slidably mounted inside the mounting groove 33. The top of the sliding block 31 is provided with a fixing opening 34, and the bottom of the fixing block 4 is installed and removed in the fixing opening 34. A spring 41 is provided on the top inner side of the mounting groove 33, and the bottom of the spring 41 is connected to the fixing block 4. A first pulling rod is provided on the outer side of the sliding block 31, and the first pulling rod extends to the outer side of the slide groove 3. A second pulling rod is provided on the top of the fixing block 4, and the second pulling rod extends to the top outer side of the mounting groove 33. When the hexagonal rods 21 on both sides are installed in the internal hexagonal columns on both sides, the fixing block 4 is in a certain position. The fixing port 34 is connected to the spring 41, which pushes the fixing block 4 to insert it into the fixing port 34. At this time, the position of the second internal hexagonal column 32 can be fixed. When it is necessary to disassemble the screen 2, first pull the second pulling rod upward, which will drive the fixing block 4 to compress the spring 41 and disengage from the fixing port 34, thus releasing the fixation of the sliding block 31. Then, pull the sliding block 31 outward along the slide groove 3 by the first pulling rod, so that the second internal hexagonal column 32 is separated from the hexagonal rod 21 on the corresponding side. Finally, the screen 2 can be directly removed to complete the disassembly of the screen 2, which is convenient for cleaning or replacing the screen 2.

[0023] The working principle of this utility model is as follows: The hopper 11 is installed by mounting the rectangular blocks 13 on both sides into the U-shaped groove 12; conversely, the hopper 11 can be directly disassembled for easy cleaning. The screen 2 is installed by installing the hexagonal rods 21 on both sides into the internal hexagonal columns. During feeding, the material is first poured into the screen 2, screened by the screen 2, and then enters the hopper 11. The motor 24 drives the internal hexagonal columns to rotate back and forth, thereby... The rotating screen 2 can effectively ensure the material falls through and improve the screening efficiency. When it is necessary to disassemble the screen 2, first pull the second pulling rod upward to drive the fixed block 4 to compress the spring 41 and disengage from the fixed port 34, thereby releasing the fixation of the sliding block 31; then pull the sliding block 31 outward along the slide groove 3 by the first pulling rod, so that the second internal hexagonal column 32 is separated from the hexagonal rod 21 on the corresponding side; finally, the screen 2 can be directly removed to complete the disassembly of the screen 2, which is convenient for cleaning or replacement of the screen 2.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
