Description

Technical Field

[0001] This utility model belongs to the field of grinding, and specifically relates to a grinding mill for electronic components. Background Technology

[0002] In the production of electronic components, it is often necessary to refine raw materials to micron-level or even finer particle sizes to meet the demands of precision manufacturing. Can mills, through the impact and friction between the abrasive particles inside the grinding jar and the material, can effectively pulverize materials to the required particle size.

[0003] Because the grinding jar rotates continuously during operation, it is prone to axial movement, leading to problems such as jar collisions and detachment. These issues result in jar damage, equipment failure, and downtime, increasing production costs and reducing efficiency. Therefore, existing grinding mills use limiting rubber rings on the rotating rollers to restrict axial movement of the grinding jar and improve the mill's stability. However, existing limiting rubber rings typically rely on friction with the roller surface for fixation, making position adjustments and replacements inconvenient, especially when changing grinding jars of different sizes. Adjusting the limiting rings is time-consuming and labor-intensive, and consistent adjustment for each ring is difficult, increasing downtime and reducing production efficiency, particularly with frequent changes to different jar sizes. Utility Model Content

[0004] To overcome the shortcomings and problems of existing technologies, improve the adjustment and replacement efficiency of the limiting rubber ring, and reduce downtime, this utility model provides a grinding mill for electronic components.

[0005] This utility model is achieved through the following technical solution:

[0006] A grinding mill for electronic components includes a frame, on which a drive roller and a driven roller are provided. The drive roller is connected to a rotary motor. Both the drive roller and the driven roller are fitted with a limiting ring assembly. Both the drive roller and the driven roller have a plurality of slots arranged axially on their roller surfaces. The end of the limiting ring assembly is provided with a buckling mechanism that cooperates with the slots.

[0007] The limiting ring assembly includes an inner ring, one end of which is provided with a stop part, and the other end is connected to a stop cover. A limiting rubber ring is provided between the stop part and the stop cover.

[0008] The limiting rubber ring includes a contact part and a limiting part, and the limiting part is sleeved on the outer wall of the blocking part.

[0009] The cover and the inner ring end are threaded together.

[0010] The latching mechanism includes a sliding seat and a locking plate. The sliding seat is located on the end face of the blocking part. One side of the locking plate is provided with a sliding part that cooperates with the sliding seat. A baffle is provided at the groove opening of the sliding seat. An elastic element is provided between the baffle and the sliding part.

[0011] Both the driving roller and the driven roller have polygonal cross-sections.

[0012] Both the driving roller and the driven roller are provided with at least two rows of slots.

[0013] The top surface of the frame is provided with an adjustment groove, and the end of the driven roller is connected to the adjustment groove.

[0014] A frequency converter is also provided on one side of the frame.

[0015] The limiting ring assembly of this invention includes an inner ring, a stop cover, and a limiting rubber ring. The limiting rubber ring is located on the inner ring, and can be quickly replaced by opening the stop cover.

Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , 2 As shown, a grinding mill for electronic components includes a frame 100, on which a drive roller 110 and a driven roller 120 are mounted. During operation, the grinding jar is placed between the drive roller 110 and the driven roller 120, and the drive roller 110 drives the grinding jar to rotate for grinding. The drive roller 110 is connected to a rotary motor 102, which provides power for the rotation of the drive roller 110. Both the drive roller 110 and the driven roller 120 are fitted with a limiting ring assembly 130, which includes an inner ring 131 made of metal, capable of supporting heavy grinding jars and improving stability. One end of the inner ring 131 is provided with a stop part 1311, and the other end is connected to a stop cover 132. The stop cover 132 and the end of the inner ring 131 are threaded together. A limiting rubber ring 133 is provided between the stop part 1311 and the stop cover 132. The stop part 1311 and the stop cover 132 can prevent the rubber ring from loosening.

[0023] like Figure 2 , 3 As shown, the limiting ring 133 includes a contact portion 1331 and a limiting portion 1332. The limiting portion 1332 is sleeved on the outer wall of the abutment portion 1311. When the equipment is working, the grinding jar is placed above the contact portion 1331. The contact portion 1331 can provide greater friction and improve transmission efficiency, while the limiting portion 1332 is used to restrict the axial movement of the grinding jar. The cross-sections of the driving roller 110 and the driven roller 120 are both quadrilateral. When the limiting ring assembly 130 is sleeved on the driving roller 110 and the driven roller 120, the quadrilateral structure of the driving roller 110 and the driven roller 120 can better drive the limiting ring assembly 130 to rotate, preventing the problem of insufficient friction caused by the circular roller.

[0024] like Figure 1 , 3As shown in Figure 4, both the driving roller 110 and the driven roller 120 have a plurality of axially arranged slots 101 on their roller surfaces. The slots 101 are evenly spaced and are used to adjust the position of the limiting ring assembly 130 on the driving roller 110 and the driven roller 120. The end of the limiting ring assembly 130 is provided with a latching mechanism 140 that cooperates with the slots 101. The latching mechanism 140 includes a sliding seat 141 and a latching plate 142. The sliding seat 141 is located on the end face of the abutment part 1311. One side of the latching plate 142 is provided with a sliding part 1421 that cooperates with the sliding seat 141. A baffle 143 is provided at the opening of the slot of the sliding seat 141. An elastic element 144, which is a spring, is provided between the baffle 143 and the sliding part 1421. The clamping plate 142 slides on the slide groove seat 141 via the sliding part 1421. When the limiting ring assembly 130 is installed on the driving roller 110 or the driven roller 120, the spring force will push the sliding part 1421 to slide towards the bottom of the groove seat 141, causing the clamping plate 142 to move towards the roller surface. When the limiting ring assembly 130 moves to the corresponding position, the end of the clamping plate 142 will be inserted into the clamping groove 101, thereby fixing the limiting ring assembly 130 at the corresponding position on the driving roller 110 or the driven roller 120.

[0025] like Figure 1 , 3 As shown in Figure 4, both the driving roller 110 and the driven roller 120 have two rows of slots 101, with each row located on a different opposite roller surface. The cooperation of two sets of latching mechanisms 140 and the two rows of slots 101 improves the axial stability of the limiting ring assembly 130 and prevents damage caused by excessive force on a single latching mechanism 140. When the limiting ring assembly 130 needs to be moved, the latching plate 142 is pushed towards the slot of the sliding seat 141 to disengage it from the slot 101. After moving the limiting ring assembly 130 to the corresponding position, the latching plate 142 is released, allowing it to engage with the slot 101. The top surface of the frame 100 is provided with an adjustment groove 103, and the end of the driven roller 120 is connected to the adjustment groove 103. When changing grinding jars of different sizes, the wheelbase between the driven roller 120 and the driving roller 110 can be adjusted via the adjustment groove 103. A variable frequency drive 104 is also provided on one side of the frame 100. The variable frequency drive 104 is used to control the speed of the rotary motor 102, thereby controlling the speed of the grinding jar.

[0026] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
