Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a three-roll grinding device for a high-viscosity UV-LED curing system. Background Technology

[0002] Three-roll mills, also known simply as three-roll grinders, can be divided into experimental and production types. The working principle of a three-roll mill is that it achieves a grinding effect through the mutual extrusion and friction at different speeds of the surfaces of three horizontal rollers. High-viscosity UV-LED curing systems refer to systems that use high-viscosity UV-LED light sources for curing. UV-LED curing technology is a technique that uses light emitted by ultraviolet light-emitting diodes (LEDs) to cure materials such as UV inks, UV adhesives, and UV coatings. Under UV light (with a specific wavelength and intensity), materials will cure or harden (polymerize), and compared to traditional UV light curing, it is faster, more efficient, energy-saving, and environmentally friendly. Three-roll mills are the most effective grinding and dispersing equipment for high-viscosity materials.

[0003] Existing three-roll mill grinding equipment requires manual cleaning after grinding operations. Manual cleaning is labor-intensive, cannot efficiently remove residues, and improperly cleaned grinding rollers will not be clean enough, affecting the grinding effect in the next cycle. In addition, the equipment is prone to overheating, which affects product quality and the service life of the equipment, and has low cooling efficiency. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the problem that manual cleaning after grinding operations using a three-roll mill is labor-intensive, inefficient in removing residues, and thus affecting the grinding effect of the next product.

[0006] (2) Technical solution

[0007] The technical solution of this utility model is as follows: a three-roller grinding device for a high-viscosity UV-LED curing system, comprising a three-roller grinding device body, including a baffle, a cleaning component, and a moving component. Three grinding rollers are arranged on the upper part of the three-roller grinding device body. A baffle is arranged between two rollers on the surface of the three-roller grinding device body, with both sides of the baffle having a quarter-circle arc structure. The baffle is attached to the surface between the two rollers. A cleaning component is arranged on the surface of the three-roller grinding device body. A moving component is arranged between the three-roller grinding device body and the cleaning component. When cleaning of the roller surface is required, a servo motor is activated to drive one end of the moving plate. The fixed plate slides on the surface of the lead screw, thereby enabling the baffle on the other end of the moving plate to move on the surface of the grinding roller shaft of the three-roll grinding device body for cleaning. It has good performance, is convenient for cleaning residues, does not require manual cleaning, and improves cleaning efficiency. The position of the baffle on the grinding roller of the three-roll grinding device body can be adjusted by rotating the lead screw, which has good flexibility. By setting a moving component, the position of the baffle can be changed by pushing the moving seat. By installing a limit block, it can slide in the limit groove opened on the surface of the fixed block B, which can limit the position of the moving seat and improve stability.

[0008] Furthermore, the cleaning assembly includes a fixed block A, a movable plate, a connecting block, a lead screw, a fixed plate, a mounting plate, a servo motor, and a threaded rod. Fixed blocks A are symmetrically arranged above the surface of the three-roll grinding device body. A movable plate is inserted into a hole on the surface of fixed block A. An L-shaped mounting plate is mounted on the surface of fixed block A. A threaded rod is rotatably connected to the surface of the mounting plate via a bearing. A servo motor is mounted on the surface of fixed block A away from the threaded rod. The output end of the servo motor is connected to one end of the threaded rod. A fixed plate is threadedly connected to the surface of the threaded rod. The fixed plate is connected to one end of the movable plate. A connecting block is mounted on the surface of the movable plate away from the fixed plate. A lead screw is located on the surface of the connecting block. A lead screw is inserted into the threaded hole. One end of the lead screw passes through the connecting block and is rotatably connected to the baffle. By setting a cleaning component, the baffle can limit the grinding range of high-viscosity solidified materials when not in use. When it is necessary to clean the surface of the roller shaft, the fixed plate at one end of the moving plate is slid on the surface of the lead screw by starting the servo motor. This allows the baffle on the other end of the moving plate to move on the surface of the grinding roller shaft of the three-roll grinding device body for cleaning. The effect is good, the removal of residue is convenient, no manual cleaning is required, and the cleaning efficiency is improved. The position of the baffle on the grinding roller of the three-roll grinding device body can be adjusted by rotating the lead screw, which provides good flexibility.

[0009] Furthermore, slide rods are installed on both sides of the baffle and on both sides of the lead screw. A limit plate is installed at one end of the slide rod that passes through the connecting block. By installing slide rods on the baffle, the baffle can be limited during the up and down adjustment process, thereby further improving the stability of the baffle in removing material from the surface of the roller.

[0010] Furthermore, stabilizing blocks with a convex-shaped structure are symmetrically installed on the surface of the moving plate, and a through groove adapted to the stabilizing block is opened on the surface of the fixed block A. The stabilizing block slides in the through groove opened on the surface of the fixed block A. By installing convex-shaped stabilizing blocks on both sides of the moving plate, the stability effect of the moving plate during the movement process can be further improved.

[0011] Furthermore, the moving component includes a fixed block B, a moving seat, a limiting block, and a limiting groove. Fixed blocks B are installed on the surface of the three-roll grinding device body below the fixed block A. A concave moving seat slides on the surface of the fixed block B. A square limiting block is installed on the concave surface of the moving seat. A limiting groove adapted to the limiting block is opened on the surface of the fixed block B. The moving seat slides on the surface of the fixed block B through the limiting block and the limiting groove. By setting the moving component, the position of the baffle can be changed by pushing the moving seat. By installing the limiting block, the moving seat can slide in the limiting groove opened on the surface of the fixed block B, which can restrict the position of the moving seat, improve stability, and provide good flexibility.

[0012] Furthermore, the concave position of the movable seat is adapted to the fixed block B, which improves the stability of the movable seat sliding on the surface of the fixed block B.

[0013] Furthermore, a positioning bolt is inserted into the threaded hole on the surface of the movable seat. One end of the positioning bolt passes through the movable seat and abuts against the surface of the fixed block B. By rotating the positioning bolt, one end of it abuts against the fixed block B, thereby fixing the position of the movable seat. This makes it convenient to use and highly flexible.

[0014] Furthermore, the three-roll mill body has a threaded cold water circulation pipe inside the roller. By connecting the threaded cold water circulation pipe to the external cooling water circulation system, rapid cooling can be achieved when the roller temperature is too high. The threaded structure of the cold water circulation pipe enables the water to circulate back, prolonging the contact time with the roller and achieving a rapid cooling effect, thus improving the service life of the device and ensuring that high-viscosity curing materials are not affected.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: When the roller shaft surface needs to be cleaned, the servo motor drives the fixed plate at one end of the moving plate to slide on the surface of the lead screw, thereby realizing the movement of the baffle on the other end of the moving plate on the surface of the grinding roller shaft of the three-roll grinding device body for cleaning. The design has good performance, makes it convenient to clean residues, eliminates the need for manual cleaning, and improves cleaning efficiency. The position of the baffle on the grinding roller of the three-roll grinding device body can be adjusted by rotating the lead screw, providing good flexibility. By setting the moving component, the position of the baffle can be changed by pushing the moving seat. By installing the limiting block, it can slide in the limiting groove opened on the surface of the fixed block B, which can limit the position of the moving seat and improve stability. The threaded cold water circulation pipe can realize the return circulation of water, prolong the contact time with the roller shaft, achieve a rapid cooling effect, and improve the service life of the device to ensure that high viscosity curing materials are not affected.

The mounting plate 38, which is arranged in an L-shape, is mounted on the surface of the fixed block A31. A threaded rod 310 is rotatably connected to the surface via a bearing. A servo motor 39 is mounted on the surface of the fixed block A31 away from the threaded rod 310. The output end of the servo motor 39 is connected to one end of the threaded rod 310. A fixed plate 37 is threadedly connected to the surface of the threaded rod 310. The fixed plate 37 is connected to one end of the moving plate 32.

The lead screw 35 passes through one end of the connecting block 34 and is rotatably connected to the baffle 2. Next, when it is necessary to clean the surface of the roller shaft, the fixed plate 37 at one end of the moving plate 32 is driven to slide on the surface of the lead screw 35 by starting the servo motor 39, thereby realizing the movement of the baffle 2 on the other end of the moving plate 32 on the surface of the grinding roller shaft of the three-roll grinding device body 1 to clean the roller shaft. The effect is good, the cleaning of residues is relatively convenient, no manual cleaning is required, and the cleaning efficiency is improved. The position of the baffle 2 on the grinding roller of the three-roll grinding device body 1 can be adjusted by rotating the lead screw 35, which provides good flexibility of use.

[0027] Slide rods 36 are installed on the surface of the baffle 2 and on both sides of the lead screw 35. A limit plate is installed at one end of the slide rod 36 that passes through the connecting block 34. By installing slide rods 36 on the baffle 2, the baffle 2 can be limited during the up and down adjustment process, which further improves the stability of the baffle 2 in removing material from the surface of the roller.
