[0016] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown in

[0017] Among them, the deburring mechanism 2 includes a fixed plate 201, the fixed plate 201 is fixedly connected to the right inner wall of the outer shell 1, a carrier plate 202 is fixedly connected to the right side of the fixed plate 201, a movable cylinder 203 is movably connected to the left side of the fixed plate 201, and the movable cylinder 203 is movably connected to the inside of the outer shell 1 through a first bearing. A plurality of push plates 204 are fixedly connected to the inner wall of the movable cylinder 203 in an annular array. A transmission cylinder 205 is movably sleeved inside the movable cylinder 203, and the transmission cylinder 205 is movably connected to the left side of the fixed plate 201. A flow sandwich layer is arranged between the transmission cylinder 205 and the movable cylinder 203. A plurality of holes 206 are arranged in an annular array on the side surface of the transmission cylinder 205. A first auger 207 is fixedly connected to the inner wall of the transmission cylinder 205. A diffusion cylinder 208 is fixedly connected to the inner wall of the end of the transmission cylinder 205 through a first bracket. A second auger 209 is fixedly connected to the inside of the diffusion cylinder 208 through a first pin, and the second auger 209 is movably connected to the inner wall of one side of the carrier plate 202 through a first plug rod. A plurality of through holes 210 are arranged in an annular array on the side surface of the diffusion cylinder 208. A driving motor 211 is fixedly connected to the right side of the carrier plate 202, and the driving motor 211 is in transmission connection with the first pin. A driving module 3 is fixedly arranged on the left sides of the transmission cylinder 205 and the movable cylinder 203. An opening and closing unit 4 is movably arranged inside the transmission cylinder 205.

[0018] By making special arrangements on the movable cylinder 203 and the transmission cylinder 205, and cooperating with the drive module 3 during use, the present invention can not only achieve the scouring of abrasive sand from the outside to the inside, deburr the hard plastic shell, and enhance the strength of the plastic shell through the flushing of abrasive sand, but also achieve the scouring of abrasive sand from the inside to the outside, deburr the plastic shell with more accumulation from the middle. At the same time, the abrasive sand flows out from the middle, which can increase the grinding contact area and is beneficial to improving the deburring efficiency.

[0019] A circulation port 201a is provided on one side of the fixed plate 201, and the circulation port 201a is communicated with the bearing plate 202. The circulation sandwich layer is communicated with the circulation port 201a. A circular slide rail 202a is fixedly connected to one side of the bearing plate 202, and the circular slide rail 202a is fixedly connected to the left side of the fixed plate 201. The diffusion cylinder 208 is movably connected to the circular slide rail 202a. During use, the plastic shell material is put into the transmission cylinder 205 through the top cover 101, and the abrasive sand is put into the bearing plate 202. Then, the drive motor 211 is operated through an external circuit mechanism. The drive motor 211 drives the diffusion cylinder 208 to rotate. Since the diffusion cylinder 208 is fixedly connected to the transmission cylinder 205, the transmission cylinder 205 rotates, and the internal plastic shell is turned over. The abrasive sand is conveyed into the diffusion cylinder 208 by the rotation of the second auger 209 and then flows out from the through hole 210 to deburr the plastic shell material with more filling. During the treatment process, the abrasive sand reaches the circulation sandwich layer from the hole 206. At this time, the abrasive sand is rotated by several push plates 204 and flows towards the fixed plate 201, and then flows into the bearing plate 202 through the circulation port 201a to achieve the effect of repeated use.

[0020] As Figure 10 shown, when deburring less plastic shell material, the drive motor 211 is operated through an external circuit mechanism. At this time, the rotation direction of the drive motor 211 is opposite. The movable cylinder 203 and the transmission cylinder 205 are meshed and driven by a transmission gear 305, so that their rotation directions are opposite. The abrasive sand remains inside the transmission cylinder 205. During the turning of the plastic shell, the abrasive sand flows into the circulation sandwich layer through the hole 206. The push plate 204 rotates through the movable cylinder 203, applies a force to the abrasive sand, and sprays the plastic shell material pile from the hole 206, increasing the contact area of the plastic shell material and improving the deburring efficiency.

[0021] In the embodiment of the present invention, as Figure 4 and Figure 5As shown in the figure, the driving module 3 includes an internal gear ring 301, which is fixedly connected to the end of the movable cylinder 203. The end of the transmission cylinder 205 is fixedly connected with an external gear ring 302. The left inner wall of the housing 1 is fixedly sleeved with a fixed ring 303. A plurality of jack cylinders 304 are fixedly connected to the side surface of the fixed ring 303 in a circular array. The output ends of the plurality of jack cylinders 304 are movably connected with transmission gears 305, and the transmission gears 305 are jointly meshed with the internal gear ring 301 and the external gear ring 302. When deburring the relatively soft plastic shell material in the present invention, the jack cylinders 304 are made to work through an external control system. The jack cylinders 304 drive the transmission gears 305 to move, so that they are separated from the internal gear ring 301 and the external gear ring 302, and the drive motor 211 is made to work through an external circuit system. The transmission cylinder 205 rotates, so that the soft plastic shell contacts the grinding sand to achieve the deburring process.

[0022] In the embodiment of the present invention, as Figure 6 shown, the opening and closing unit 4 includes a first fixing frame 401. The first fixing frame 401 is movably connected to one end of the diffusion cylinder 208 through a second pin, and the first fixing frame 401 is fixedly connected to the fixed ring 303 through a first bolt. A plurality of first movable frames 402 are movably sleeved on the end surface of the first fixing frame 401, and two adjacent first movable frames 402 are closely stacked. A first adjusting frame 403 is movably sleeved on the end surface of the first fixing frame 401. A first driving gear 404 is fixedly connected to the side of the first adjusting frame 403 away from the first movable frame 402. A first motor 405 is fixedly sleeved on the second bracket of the fixed ring 303. The output end of the first motor 405 is fixedly connected with a second driving gear 406, and the first driving gear 404 is meshed with the second driving gear 406. It is worth noting that the first fixing frame 401, the first movable frame 402 and the first adjusting frame 403 are inserted into adjacent holes in the holes on them, so that they form a folding fan frame structure to achieve the opening and closing effect of loading and unloading. At the same time, during the discharging process, the second driving gear 406 is driven by the first motor 405. Among them, the second driving gear 406 is meshed and transmitted with the first driving gear 404 to make the first adjusting frame 403 rotate. Since the first adjusting frame 403, the first fixing frame 401 and the first movable frame 402 are movably connected through pins to form a rotating joint structure, it drives a plurality of first movable frames 402 to merge to form a circulation through hole, and the plastic shell material is discharged and stored through the first auger 207 inside the transmission cylinder 205.

[0023] Working principle: This embodiment provides an automatic deburring machine for plastic case circuit breaker accessories. When in use, the plastic case material is put into the transmission cylinder 205 through the top cover 101, and the grinding sand is put into the bearing plate 202. Then, the driving motor 211 is operated through an external circuit mechanism. The driving motor 211 drives the diffusion cylinder 208 to rotate. Since the diffusion cylinder 208 is fixedly connected to the transmission cylinder 205, the transmission cylinder 205 rotates, and the plastic case inside is turned over. The grinding sand is conveyed into the diffusion cylinder 208 by the rotation of the second auger 209 and then flows out from the through hole 210 to perform deburring treatment on the plastic case material with more filling; during the treatment process, the grinding sand reaches the circulation interlayer from the hole 206. At this time, the grinding sand is rotated by several push plates 204 and flows towards the fixed plate 201, and then flows into the bearing plate 202 through the circulation port 201a to achieve the effect of repeated use; as Figure 10 shown, when deburring less plastic case material, the driving motor 211 is operated through an external circuit mechanism. At this time, the rotation direction of the driving motor 211 is opposite. The movable cylinder 203 and the transmission cylinder 205 are meshed and driven by the transmission gear 305, so that their rotation directions are opposite. The grinding sand remains inside the transmission cylinder 205. During the turning of the plastic case, the grinding sand flows into the circulation interlayer through the hole 206. The push plate 204 rotates through the movable cylinder 203 to apply a force to the grinding sand and spray it on the plastic case material pile from the hole 206, increasing the contact area of the plastic case material and improving the deburring efficiency; and when deburring softer plastic case material, the top cylinder 304 is operated through an external control system. The top cylinder 304 drives the transmission gear 305 to move, so that it is separated from the internal gear ring 301 and the external gear ring 302, and the driving motor 211 is operated through an external circuit system. The transmission cylinder 205 rotates, so that the soft plastic case contacts the grinding sand to achieve deburring treatment; at the same time, during the discharging process, the second driving gear 406 is driven by the first motor 405. Among them, the second driving gear 406 is meshed and driven with the first driving gear 404 to make the first adjusting frame 403 rotate. Since the first adjusting frame 403, the first fixing frame 401 and the first movable frame 402 are movably connected by pins to form a rotating joint structure, it drives several first movable frames 402 to merge to form a circulation through hole, and the plastic case material is discharged and stored through the first auger 207 inside the transmission cylinder 205.
