Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, this embodiment provides an embodiment of an eccentric drum positioning mechanism of a particle removal and purification rotary device.

[0025] An eccentric drum positioning mechanism for a particle de-powdering and purification rotary device comprises two support seats 1, an eccentric drum body 2 is arranged between the two support seats 1, a gear is fixedly mounted on the eccentric drum body 2, and a transmission motor 3 engaged with the gear is arranged on one side of the eccentric drum body 2, a positioning mechanism body 4 is arranged on the eccentric drum body 2, the positioning mechanism body 4 comprises a mounting plate 5 fixedly mounted on one side of the eccentric drum body 2, a dividing toothed disc 6 sleeved on the eccentric drum body 2 is mounted on the mounting plate 5, a pulse counting photoelectric switch 7 is provided on the top and side of the dividing toothed disc 6, and a circle counting photoelectric switch 8 is fixedly mounted on the front of the dividing toothed disc 6. By setting the positioning mechanism body 4, the eccentric cylinder body 2 can be effectively positioned. A dividing gear disc 6 is installed on the eccentric cylinder body 2, and two pulse counting photoelectric switches 7 and a circle counting photoelectric switch 8 are set on the dividing gear disc 6. The pulse counting photoelectric switch 7 is positioned according to the teeth on the dividing gear disc 6 and its own circumference, and the 360 degrees of the dividing gear disc 7 are divided into 1440 pulses. The circle counting photoelectric switch 8 rotates with the dividing gear disc 6 and counts and positions in units of one circle. When the circle counting photoelectric switch 8 counts one circle, the pulse signal count is 1440. When it is necessary to locate the feeding and unloading stop position, the corresponding pulse signal count value is adjusted through the program to control the transmission motor 3 to brake the eccentric cylinder body 2 to achieve precise positioning.

[0026] A fixed disk 9 is provided on one side of the indexing gear disk 6. The fixed disk 9 and the mounting plate 5 are directly fixedly connected by nuts 10 and bolts 11. Two screws 12 movably mounted through a fixing frame are provided on the support seat 1. A support plate 13 connected to the pulse counting photoelectric switch 7 is movably mounted on the screw 12 through a thread. One end of the screw 12 is provided with an anti-slip groove 14. By setting the fixing plate 9, the nut 10 and the bolt 11, the installation of the indexing gear disc 6 is tightened to prevent it from loosening and falling off. At the same time, it also has the function of disassembly, which is convenient for disassembly and replacement when the indexing gear disc 6 is damaged. By setting the screw 12 and the support plate 13, the pulse counting photoelectric switch 7 can be driven to rise through the support plate 13 under the action of the thread by rotating the screw 12, which can avoid the pulse counting photoelectric switch 7 from obstructing the indexing gear disc 6 when it is disassembled. After the indexing gear disc 6 is installed, rotating the screw 12 can make the pulse counting photoelectric switch 7 descend and contact the indexing gear disc 6. By setting the anti-slip groove 14, the friction force at one end of the screw 12 can be increased, which is convenient for twisting and rotating it.

[0027] Limit rods 15 fixedly connected to the fixing frame are provided on both sides of the screw rod 12, and limit rings 16 slidingly connected to the limit rods 15 are fixedly installed on both sides of the support plate 13. A fixing frame 17 is fixedly installed on the top of the support plate 13, and a spring 18 is fixedly installed inside the fixing frame 17. A card block 19 is fixedly installed on one end of the spring 18. A card slot 20 that engages with the card block 19 is provided on the pulse counting photoelectric switch 7. A pull rod 21 is fixedly installed on the top of the card block 19, and the pull rod 21 passes through the spring 18 and extends to the outside of the fixed frame 17. Through the setting of the limit rod 15 and the limit ring 16, under the connection limit of the limit rod 15 and the limit ring 16, the support plate 13 can smoothly drive the pulse counting photoelectric switch 7 to rise and fall, and avoid the pulse counting photoelectric switch 7 from tilting and affecting the counting effect. Through the setting of the fixed frame 17, the spring 18, the block 19, the slot 20 and the pull rod 21, the block 19 extends to the slot 20 provided on the pulse counting photoelectric switch 7 under the action of the spring 18, and connects the pulse counting photoelectric switch 7 and the support plate 13 by snapping together. This structure is relatively simple in installation and disassembly functions, and is convenient for replacing the pulse counting photoelectric switch 7 when it fails.

[0028] In this embodiment, if Figure 1-Figure 5 As shown, the working process of the eccentric drum positioning mechanism of the particle removal and purification rotary equipment provided in this embodiment is as follows:

[0029] Step 1: When purifying the material, the transmission motor 3 drives the eccentric cylinder body 2 to rotate, and the indexing gear plate 6 on the eccentric cylinder body 2 rotates with it. At this time, the pulse counting photoelectric switch 7 and the circle counting photoelectric switch 8 are started to count the pulses and circles according to the rotation of the indexing gear plate 6. When feeding and discharging positioning are required, the corresponding pulse signal counting value is adjusted by the program to control the transmission motor 3 to brake the eccentric cylinder body 2 to achieve precise positioning;

[0030] Step 2: When the indexing gear disc 6 is damaged and needs to be replaced, first rotate the screw 12 through the support plate 13 to drive the pulse counting photoelectric switch 7 to rise, and the pulse counting photoelectric switch 71 will be disengaged from the indexing gear disc 6. Then remove the circle counting photoelectric switch 8 from the indexing gear disc 6. Then remove the fixing plate 9, nut 10 and bolt 11 used for fixing and separate them from the mounting plate 5. Then, the indexing gear disc 6 can be removed from the eccentric cylinder body 2 for replacement. After replacement, continue to fix it with the fixing plate 9, nut 10 and bolt 11. Finally, reset the pulse counting photoelectric switch 7 and the circle counting photoelectric switch 8 on the indexing gear disc 6.

[0031] Step 3: When the pulse counting photoelectric switch 7 is damaged, the block 19 can be separated from the card slot 20 by pulling the pull rod 21, and the pulse counting photoelectric switch 7 can be removed from the support plate 13 and replaced. During installation, the block 19 is a trapezoidal structure. The pulse counting photoelectric switch 7 is directly inserted into the support plate 13 to squeeze the block 19 to make it rise. After the pulse counting photoelectric switch 7 reaches the engaged position, the block 19 descends under the action of the spring 18 and engages in the card slot 20, completing the installation and fixation of the pulse counting photoelectric switch 7.

[0032] In summary, in this embodiment, according to the eccentric drum positioning mechanism of the particle de-powdering and purification rotary equipment of this embodiment, the installation of the indexing gear disc 6 is tightened by the arrangement of the fixing plate 9, the nut 10 and the bolt 11 to prevent it from loosening and falling off, and at the same time, it also has the function of disassembly, which is convenient for disassembly and replacement when the indexing gear disc 6 is damaged. By the arrangement of the screw 12 and the support plate 13, the rotating screw 12 can drive the pulse counting photoelectric switch 7 to rise through the support plate 13 under the action of the thread, which can avoid the pulse counting photoelectric switch 7 from obstructing the indexing gear disc 6 when it is disassembled. After the indexing gear disc 6 is installed, rotating the screw 12 can make the pulse counting photoelectric switch 7 descend and contact with the indexing gear disc 6, through the anti-slip The arrangement of the groove 14 can increase the friction force at one end of the screw 12, making it easier to twist and rotate it. Through the arrangement of the limit rod 15 and the limit ring 16, under the connection limit of the limit rod 15 and the limit ring 16, the support plate 13 can smoothly drive the pulse counting photoelectric switch 7 to rise and fall, thereby preventing the pulse counting photoelectric switch 7 from tilting and affecting the counting effect. Through the arrangement of the fixed frame 17, the spring 18, the block 19, the slot 20 and the pull rod 21, the block 19 extends to the slot 20 provided on the pulse counting photoelectric switch 7 under the action of the spring 18, and connects the pulse counting photoelectric switch 7 and the support plate 13 by engaging. This structure is relatively simple in installation and disassembly functions, and is convenient for replacing the pulse counting photoelectric switch 7 when it fails.
