Description

Technical Field

[0001] The utility model relates to the technical field of toner processing, in particular to a grinding mechanism for toner production. Background Art

[0002] Toner is a common name for pigments, which include organic pigments, inorganic pigments, solvent dyes, fluorescent pigments, pearlescent pigments, fluorescent brighteners, etc., and can be added to plastics and paints for dyeing. Therefore, toner needs to be ground into fine powder through efficient grinding before it can be used. Existing grinding devices usually grind by contacting the grinding seat with the grinding block, but the grinding position is single and the grinding structure is complex. The toner can only be ground once, and the toner can be repeatedly ground multiple times, and the grinding effect of the toner is not ideal.

[0003] The published patent document CN216499589U proposes a grinding mechanism for toner production, comprising a grinding barrel, an end cover matched with the grinding barrel, and a grinding combination located inside the grinding barrel and fixedly mounted with the end cover; the grinding combination comprises a driving motor fixedly mounted on the end cover, a rotating shaft fixed to the output end of the driving motor, an upper grinding block mounted on the lower end of the rotating shaft, a lower grinding block located below the upper grinding block and fixed to the rotating shaft, and a fixed grinding block arranged between the upper and lower grinding blocks and in contact with the upper and lower grinding blocks; by matching the upper grinding block with the upper end of the fixed grinding block, the toner is subjected to a primary grinding process, and then by matching the lower grinding block with the lower end of the fixed grinding block, the toner is subjected to a secondary grinding process, which can improve the grinding effect and quality of the toner.

[0004] The inventor has found through research that there are still the following problems:

[0005] 1. The upper grinding block and the lower grinding block are fixedly connected to the rotating shaft. The long-term grinding operation between the fixed grinding block and the upper and lower grinding blocks will cause wear of the fixed grinding block, the upper grinding block and the lower grinding block, thereby increasing the grinding gap between the upper and lower grinding blocks and the fixed grinding block, thereby greatly reducing the grinding effect of the toner and the grinding quality cannot be guaranteed.

[0006] 2. When the grinding gap between the upper grinding block, the lower grinding block and the fixed grinding block increases, the grinding effect of the toner is greatly reduced, so that the unqualified toner is discharged from the discharge port together with the qualified toner, and the unqualified toner cannot be filtered out.

[0007] Therefore, a grinding mechanism for toner production is needed to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0028] A material guide plate 13 is provided below the lower grinding block 12, and a draw box 14 slidably connected to the barrel body 1 is provided below the material guide plate 13. A through groove 15 is provided on the inner side of the draw box 14, and slide grooves 16 are provided on the inner walls on both sides of the through groove 15. A sieve plate 18 slidably connected to two groups of slide grooves 16 are placed on the inner side of the through groove 15, and grooves 17 are provided on one side of the two groups of slide grooves 16. A reciprocating motion mechanism that drives the sieve plate 18 to reciprocate is installed on the inner side of the two groups of grooves 17.

[0029] Specifically, by starting the first motor 8, the first motor 8 can drive the rotating shaft 9 to rotate, and the rotating shaft 9 can drive the upper grinding block 11 and the lower grinding block 12 to rotate, and under the joint action of the fixed grinding block 3, the input color powder can be fully ground. The upper grinding block 11 and the lower grinding block 12 connected by threads can adjust the gap between the upper grinding block 11 and the lower grinding block 12 and the fixed grinding block 3 when the wear gap increases, thereby ensuring the grinding quality of the color powder. The set pouring plate 13 can conveniently introduce the ground color powder into the sieve plate 18, and the set reciprocating motion mechanism can drive the sieve plate 18 to reciprocate, so that the sieve plate 18 can perform a reciprocating and continuous screening operation on the color powder. Further, through the above structure, the color powder grinding effect can be improved while filtering out unqualified color powder, and the grinding quality of the color powder is guaranteed.

[0030] Among them, the reciprocating motion mechanism includes a second motor 23 installed at the bottom of the groove 17, the output end of the second motor 23 is connected to a turntable 22, and a rotating rod 21 is welded at the top of the turntable 22 near the edge. A limiting ring 20 is sleeved on the outer side of the rotating rod 21, and one end of the limiting ring 20 is welded to one side of the sieve plate 18. By starting the two groups of second motors 23, the two groups of second motors 23 can drive the two groups of turntables 22 to rotate, and the two groups of turntables 22 can drive the two groups of rotating rods 21 to rotate. While the two groups of rotating rods 21 rotate, under the joint action of the sieve plates 18 slidably connected to the two groups of slide grooves 16, the limiting ring 20 can be driven to reciprocate, and the two groups of limiting rings 20 can drive the sieve plate 18 to reciprocate, so that the toner can be screened through the reciprocating motion of the sieve plate 18, and then through the setting, unqualified toner can be filtered and removed, thereby ensuring the discharge quality of the toner.

The two groups of limiting blocks 5 are slidingly connected with the two groups of limiting grooves 4 respectively. Through the set limiting grooves 4 and limiting blocks 5, the fixed grinding block 3 can be limited to prevent it from rotating and affecting the grinding effect of the color powder.

[0033] Among them, a slope 24 is provided at the bottom of the inner cavity of the barrel body 1, and a discharge port 25 is opened on one side of the slope 24.

When wear and gap increase between the fixed grinding block 3 and the upper grinding block 11 and the lower grinding block 12, the gap between the upper grinding block 11 and the lower grinding block 12 and the fixed grinding block 3 can be adjusted by rotating the threaded upper grinding block 11 and the lower grinding block 12, so as to ensure the grinding quality of the color powder;

[0035] By setting the pouring plate 13, the ground color powder can be conveniently introduced into the sieve plate 18, and then, by starting the two sets of second motors 23, the two sets of second motors 23 can drive the two sets of turntables 22 to rotate, and the two sets of turntables 22 can drive the two sets of rotating rods 21 to rotate. While the two sets of rotating rods 21 are rotating, the limit rings 20 can be driven to reciprocate under the joint action of the sieve plate 18 slidably connected to the two sets of slide grooves 16, and the two sets of limit rings 20 can drive the sieve plate 18 to reciprocate, so that the color powder can be screened by the reciprocating motion of the sieve plate 18.
