Description

Technical Field

[0001] This utility model relates to the technical field of grinding mill baffle equipment, specifically to a positioning device for a material baffle of a three-roll grinding mill. Background Technology

[0002] The material baffles in a three-roll mill are fixed in position and cannot be flexibly adjusted according to the grinding requirements of the material. This design limits the adaptability and efficiency of the mill, as different materials or different grinding stages may require different baffle positions to optimize the grinding effect. Furthermore, the fixed baffle positions are inconvenient to replace, requiring additional tools and time, which reduces production efficiency and increases maintenance costs.

[0003] According to the search, a material baffle adjustment device for a three-roll mill with announcement number CN214717046U is provided. It includes a concave mounting frame, three rollers and two material baffles. The outer sides of the two material baffles are provided with two insert rods. The mounting frame is provided with insertion holes for the insert rods. An elastic element is also provided between the material baffles and the mounting frame. Pull wires are connected to the outer sides of the two material baffles. Guide wheels one and two are provided on both sides of the concave part of the mounting frame. A slider is also provided on the rear side of the mounting frame. The mounting frame is also provided with a screw mechanism to drive the slider to move up and down. The other end of the pull wire passes through guide wheels one and two on the same side and then connects to the slider. The pull wire is kept taut.

[0004] The above-mentioned device moves the slider down, causing the two material baffles to move away from each other; moves the slider up, causing the elastic element to bring the two material baffles closer together and reset them. At the same time, the positions of the two material baffles are adjusted. However, the material baffles are fixed and not easy to disassemble. Therefore, a material baffle for a three-roll mill that is easy to disassemble was designed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a positioning device for the material baffle of a three-roll mill, which facilitates the disassembly and position adjustment of the baffle.

Symmetrical limiting blocks are fixed to the upper center of the baffle. The spacing between each pair of limiting blocks matches the width of the support rod. The limiting blocks have through channels that are coaxial with the mounting holes. Bolts pass through the channels of the limiting blocks and the corresponding mounting holes, and the bolts are threaded to fit nuts.

[0008] As a further limitation of this technical solution, the vertical moving module is connected to the horizontal moving module. The horizontal moving module includes slides opened on both sides of the upper part of the grinding machine. Each slide is provided with a slider. The upper side of each slider is fixedly connected to one end of the connecting rod. Each connecting rod is connected to the baffle plate through the vertical moving module.

[0010] As a further limitation of this technical solution, the grinding machine includes a first grinding roller, a second grinding roller and a third grinding roller, and the grinding machine is connected to a transmission assembly, which is driven by a drive motor.

[0011] As a further limitation of this technical solution, the slide rails are arranged on both sides of the upper part of the outer shell of the grinding machine, corresponding to the positions of the first grinding roller and the second grinding roller.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are:

[0013] The precise position adjustment of the baffle plate is achieved through the horizontal and vertical movement modules, enabling the grinder to adapt to different materials and grinding needs, thereby improving grinding efficiency and quality.

[0014] The baffle plate can be quickly fixed or unlocked by the threaded engagement of bolts and nuts, making the replacement and adjustment of the baffle plate simple and quick without the need for additional tools, reducing the difficulty of operation and maintenance time. The quick disassembly and installation design of the baffle plate makes maintenance and cleaning more convenient and improves the maintenance efficiency of the equipment.

The vertical movement module includes a support rod 12, one end of which is fixedly connected to one end of a connecting rod 2. The support rod 12 has several through mounting holes 11. Symmetrical limiting blocks 8 are fixed to the upper center of the baffle 1. The spacing between each pair of limiting blocks 8 matches the width of the support rod 12. The limiting blocks 8 have through holes that are coaxial with the mounting holes 11. Bolts 9 pass through the holes in the limiting blocks 8 and the corresponding mounting holes 11. The bolts 9 are threadedly engaged with nuts 10.

[0026] The vertical moving module is connected to the horizontal moving module. The horizontal moving module includes slides 3 on both sides of the upper part of the grinding machine 14. Each slide 3 is provided with a slider 6. The upper side of each slider 6 is fixedly connected to one end of the connecting rod 2.

[0027] In this embodiment, the position of the baffle plate 1 is adjusted by setting a baffle plate positioning component, the horizontal movement module adjusts the horizontal position of the baffle plate, the movement of the slider 6 in the slide rail 3 drives the connecting rod 2 to move, the connecting rod 2 drives the vertical movement module to move, thus moving the baffle plate 1. The vertical movement module adjusts the vertical position of the baffle plate 1. By unscrewing the nut 10 and pulling out the bolt 9, the baffle plate 1 is moved, which drives the limit block 8 to move, thus adjusting the position of the baffle plate 1. By setting the bolt 9 and the nut 10, the connection between the baffle plate 1 and the limit block 8 is locked, thus fixing the position of the baffle plate 1. The baffle plate 1 can be easily replaced by fixing the bolt and nut 10, and the operation is simple.

Through the screw 5 threadedly engaging with the slider 6, the slider 6 can move following the rotating screw 5, thereby realizing the movement of the connecting rod 2 and the baffle plate 1. The screw 5 and the slider 6 are threadedly self-locking. Threaded self-locking is existing technology and will not be described in detail. Due to the threaded self-locking, no other fixing components need to be set between the screw 5 and the slider 6, which is convenient to use.

[0030] The grinding machine 14 includes a first grinding roller 143, a second grinding roller 142 and a third grinding roller 141. The grinding machine 14 is connected to a transmission assembly 7, which is driven by a drive motor 13.

[0031] Furthermore, the transmission assembly 7 includes a belt, pulleys, and gears. The first grinding roller 143, the second grinding roller 142, and the third grinding roller 141 are respectively fixed to the central shaft of the gear. The gear is disposed in the cavity of the housing of the grinding machine 14. The two ends of the belt are connected to the pulleys. One pulley is fixed to the output shaft of the drive motor 13, and the other pulley is fixed to the central shaft of one of the gears.

[0032] The slide rails 3 are located on both sides of the upper part of the outer shell of the grinding machine 14, corresponding to the positions of the first grinding roller 143 and the second grinding roller 142.

[0033] In this embodiment, the slide rail 3 is set at the position corresponding to the first grinding roller 143 and the second grinding roller 142, so as to facilitate the adjustment of the position of the baffle plate 1.

[0034] When the position of baffle 1 needs to be adjusted, the position of baffle 1 can be adjusted by the horizontal moving component and the vertical moving component.
