Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical labels such as: first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0029] Embodiment: An automatic loading and unloading mechanism for a powder feeding roller grinding machine, referring to Figure 1 - Figure 3 , comprising: a first support frame 101; a first motor 102 fixedly installed on the first support frame 101; a rotating plate 103 rotatably installed on the first support frame 101, with the output end of the first motor 102 fixed to the rotating plate 103; a grinding roller 104 rotatably installed on the rotating plate 103; a second motor 105 fixedly installed on the rotating plate 103, with the output end of the second motor 105 fixed to the grinding roller 104; support blocks 401 rotatably installed on the left and right sides at the rear of the first support frame 101, and the support blocks 401 are used to support the powder feeding roller 000.

[0030] The first motor 102 drives the rotary plate 103 to rotate, and can move the grinding roller 104 close to the support block 401 and contact the powder feeding roller 000 located thereon. The second motor 105 drives the grinding roller 104 to rotate to polish the powder feeding roller 000.

[0031] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , further comprising: a second support frame 201, the first support frame 101 and the second support frame 201 are fixedly installed; mounting plates 202 fixedly installed on the left and right sides of the front part of the second support frame 201; a control unit group symmetrically arranged on the two mounting plates 202; The control unit group includes: a rod portion is arranged on the mounting plate 202, and a mounting ring seat 203 is slidably installed on the mounting plate 202 through the rod portion; a movable ring 204 is slidably installed on the mounting ring seat 203; a bearing 205 is rotatably installed on the movable ring 204; a pressing plate 206 is fixedly installed on the bearing 205; a first spring 207 is fixedly installed between the movable ring 204 and the mounting ring seat 203; a rotating cylinder 208 is rotatably installed on the mounting plate 202; a transmission cylinder 209 is cross-key connected to the rotating cylinder 208, a convex ring is arranged outside the transmission cylinder 209, a channel is arranged inside the mounting ring seat 203, and the transmission cylinder 209 and the mounting ring seat 203 are rotatably installed through the cooperation of the ring and the channel, so that the movement of the mounting ring seat 203 can control the movement of the transmission cylinder 209, and the transmission cylinder 209 can move to contact the pressing plate 206. Grooves for increasing friction are arranged on the contacting surfaces of the transmission cylinder 209 and the pressing plate 206, so that the rotation of the transmission cylinder 209 can drive the pressing plate 206 to rotate.

[0032] Place the powder feeding roller 000 between the two control unit groups, control the two mounting ring seats 203 to move closer to the middle, and the pressing plate 206 and the transmission cylinder 209 move towards the middle accordingly. First, the pressing plate 206 moves to contact the powder feeding roller 000, so that the two pressing plates 206 fix the powder feeding roller 000. Then, the mounting ring seat 203 continues to move towards the middle. At this time, the positions of the pressing plate 206 and the movable ring 204 remain unchanged, and the mounting ring seat 203 will move relative to the movable ring 204, and the first spring 207 is compressed, resulting in the distance between the pressing plate 206 and the transmission cylinder 209 decreasing until they contact. Therefore, under the action of the grooves between the transmission cylinder 209 and the pressing plate 206, the rotating cylinder 208 rotates actively, and can control the rotation of the pressing plate 206 through the transmission cylinder 209, and further control the rotation of the powder feeding roller 000; conversely, when the two mounting ring seats 203 move towards the two sides and separate from each other, first, under the restoring action of the first spring 207, the pressing plate 206 and the transmission cylinder 209 separate first, and then, the pressing plate 206 separates from the powder feeding roller 000.

[0033] Refer to Figure 1, Figure 2 , Figure 7 and Figure 8 , further comprising: a charging bin 301 fixedly installed on the top of the second support frame 201, the bottom of the charging bin 301 being inclined, and a discharge port that can only allow a single powder feeding roller 000 to pass through being provided at the lowest position of its bottom; a mounting shaft 302 rotatably installed on the second support frame 201, the mounting shaft 302 being arranged below the charging bin 301; a third motor 303 fixedly installed on the second support frame 201, the output end of the third motor 303 being fixed to the mounting shaft 302; fixed disks 304 fixedly installed at both ends of the mounting shaft 302; a feeding tray 305 fixedly installed on the two fixed disks 304, the feeding tray 305 being provided with notches adapted to the powder feeding roller 000, placing the powder feeding roller 000 between the notches, and the rotation of the feeding tray 305 can control the movement of the powder feeding roller 000; a mounting sleeve 306 fixedly installed at the bottom of the charging bin 301, the mounting sleeve 306 being sleeved outside the mounting shaft 302; guiding frames 307 fixedly installed on both sides of the mounting sleeve 306, the guiding frames 307 being used to guide the powder feeding roller 000 from the feeding tray 305 to the support block 401.

[0034] When the third motor 303 is started, it controls the rotation of the mounting shaft 302 and the fixed disks 304 and the feeding tray 305 thereon. See Figure 7 , at both ends of the powder feeding roller 000 at the discharge port of the charging bin 301 will first be supported by the feeding tray 305. When the feeding tray 305 rotates, a relative displacement is generated with the powder feeding roller 000 until the feeding tray 305 rotates its notch to the position of the powder feeding roller 000, then the powder feeding roller 000 can fall into the notch and leave the charging bin 301. Therefore, subsequently, the rotating feeding tray 305 will transport the powder feeding roller 000. The powder feeding roller 000 in the charging bin 301 automatically adjusts its position under the action of gravity, moves the next powder feeding roller 000 to the discharge port of the charging bin 301 and is supported by the feeding tray 305. See Figure 8 , as the feeding tray 305 rotates, the powder feeding roller 000 transported by the feeding tray 305 will contact the guiding frame 307, and the position of the notch on the feeding tray 305 gradually moves downward, then the powder feeding roller 000 is transferred to the guiding frame 307 and supported by the guiding frame 307. Under the guidance of the guiding frame 307, the powder feeding roller 000 is moved to the support block 401, thus realizing the automatic feeding of the powder feeding roller 000.

[0035] Refer to Figure 1 , Figure 2 and Figure 9, further comprising: a rack 211 fixedly mounted on two mounting ring seats 203, and the two racks 211 will also be slidably mounted on the other mounting ring seat 203 that is not where they are located respectively to increase the moving stability of the two mounting ring seats 203; a connecting block 212 fixedly mounted on the mounting sleeve 306; a first gear 213 rotatably mounted on the connecting block 212, and the first gear 213 meshes with both of the two racks 211 to control the two racks 211 to move synchronously and in opposite directions; a torsion spring 214 fixedly mounted between the connecting block 212 and the first gear 213; a first control ring 215 fixedly mounted on the two fixed disks 304, the first control ring 215 is provided with a notch, and an inclined surface is provided at the end of the notch of the first control ring 215, and the inclined surfaces on the two first control rings 215 are symmetrically arranged; a convex block 216 fixedly mounted on the two mounting ring seats 203, and the convex block 216 will cooperate with the inclined surface on the first control ring 215 so that when the first control ring 215 rotates, it can control the two mounting ring seats 203 to move towards the middle.

[0036] When the mounting shaft 302 controls the first control ring 215 to rotate, the inclined surface on the first control ring 215 will control the two mounting ring seats 203 to move towards the middle by squeezing the convex block 216, so that the pressing disk 206 fixes the powder feeding roller 000. After the mounting ring seats 203 finish moving, they will be continuously controlled by the first control ring 215, so that the powder feeding roller 000 is continuously fixed until the first control ring 215 rotates nearly a complete circle and the notch on it moves to the position of the convex block 216, then the convex block 216 is no longer restricted by the first control ring 215, and the torsion spring 214 resumes and reverses the first gear 213, and through the transmission of the rack 211, it controls the two mounting ring seats 203 to move towards both sides and separate from each other.

[0037] Refer to Figure 1 、 Figure 2 and Figure 12 , further comprising: a connecting shaft 221 rotatably mounted on the right mounting plate 202; a transmission belt group 222 mounted between the connecting shaft 221 and the right rotating cylinder 208; second gears 223 fixedly mounted on the connecting shaft 221 and the mounting shaft 302 respectively, the two second gears 223 mesh with each other, and there is a size difference between the two second gears 223, so that the mounting shaft 302 can accelerate the transmission and rotation of the rotating cylinder 208.

[0038] Refer to Figure 1 、 Figure 2 and Figure 10, further comprising: mounting brackets 402 fixedly installed on the left and right sides of the first support frame 101; a moving rod frame 403 slidably installed on the two mounting brackets 402; connecting groove plates 404 fixedly installed on the two support blocks 401, and each connecting groove plate 404 is slidably installed with each moving rod frame 403 through the slots thereon; a second control ring 405 fixedly installed on the fixed disk 304, a notch is provided on the second control ring 405, a slope is provided at the end of the notch of the second control ring 405, and the slope of the second control ring 405 can cooperate with the moving rod frame 403 so that when the second control ring 405 rotates, it can control the moving rod frame 403 to move forward; a second spring 406 fixedly installed between the moving rod frame 403 and the mounting bracket 402.

[0039] When the installation shaft 302 controls the second control ring 405 to rotate, the second control ring 405 controls the moving rod frame 403 to move forward, and then moves the lower end of the connecting groove plate 404 forward, and then rotates the connecting groove plate 404 to rotate the support block 401, so that the support block 401 no longer supports the powder feeding roller 000, realizing the automatic unloading of the powder feeding roller 000; the second control ring 405 will continuously control the support block 401 to keep the support block 401 in a state of not supporting the powder feeding roller 000 until the second control ring 405 rotates nearly a complete circle, so that the notch on it moves to the position of the moving rod frame 403, and the second spring 406 moves the moving rod frame 403 backward to reset, and rotates the support block 401 to a state where it can support the powder feeding roller 000.

[0040] Refer to Figure 11 , among the three features of the feeding tray 305 and its notch, the first control ring 215 and its notch, and the second control ring 405 and its notch, the range of the notch of the first control ring 215 is larger than the range of the notch of the feeding tray 305, and the range of the notch of the second control ring 405 intersects with the range of the notch of the first control ring 215, so that when the installation shaft 302 rotates, the cyclic sequence of these three control parts is: the support block 401 is rotated to a state where it can support the powder feeding roller 000 - the powder feeding roller 000 is fed onto the support block 401 - the two mounting ring seats 203 are controlled to move towards the middle - the support block 401 is rotated to a state where it does not support the powder feeding roller 000 - the two mounting ring seats 203 are controlled to move towards both sides and separate from each other - the support block 401 is rotated to a state where it can support the powder feeding roller 000, and the above cycle is repeated.

[0041] Refer to Figure 1 、 Figure 2 and Figure 13, further comprising: a discharge table 111 fixedly installed between the first support frame 101 and the second support frame 201, the discharge table 111 being arranged in an arc and inclined, with the highest position thereof being below the support block 401; a guide plate 112 fixedly installed on the discharge table 111, the guide plate 112 being arranged on the other side of the highest position on the discharge table 111, and the guide plate 112 being arranged below the grinding roller 104.

[0042] During the process of the grinding roller 104 grinding the powder feeding roller 000, the generated debris will fall and be discharged forward along the guide plate 112. When the support block 401 rotates to no longer support the powder feeding roller 000, the powder feeding roller 000 will fall and be discharged backward along the discharge table 111. In this way, when the powder feeding roller 000 is uniformly collected after processing, it is not easy to be contaminated with too much grinding debris, so as to reduce the trouble of later processing.

[0043] In summary, the complete grinding process of this mechanism is as follows: Add an appropriate amount of powder feeding rollers 000 to be polished into the loading box 301. Start the third motor 303 to control the rotation of the mounting shaft 302 and the rotating cylinder 208 on the right. During the rotation of the mounting shaft 302: the powder feeding roller 000 will be successively loaded onto the support block 401 by the feeding tray 305 and the guiding frame 307. Subsequently, the inclined surface on the first control ring 215 rotates to contact the convex block 216, controlling the mounting ring seat 203 to move towards the middle, fixing the powder feeding roller 000 located on the support block 401 with the pressing disc 206, and making the transmission cylinder 209 contact the pressing disc 206. Then, the rotating cylinder 208 on the right can control the rotation of the powder feeding roller 000, and the rotating cylinder 208 on the left rotates accordingly; after the pressing disc 206 fixes the powder feeding roller 000, the inclined surface of the second control ring 405 rotates to contact the moving rod frame 403, controlling the moving rod frame 403 to move forward, so that the support block 401 no longer supports the powder feeding roller 000, thereby reducing the wear of the rotating powder feeding roller 000 on the support block 401; then, start the first motor 102 and the second motor 105, move the rotating grinding roller 104 to contact the powder feeding roller 000, and after contact, turn off the first motor 102. At this time, the grinding roller 104 can evenly polish the powder feeding roller 000; after the polishing work is completed, the first motor 102 runs again to control the grinding roller 104 to move away. After completion, turn off the first motor 102 and the second motor 105; finally, when the fixed disc 304 rotates nearly a full circle, the notch of the first control ring 215 first moves to the convex block 216, causing the mounting ring seat 203 to move to both sides, the pressing disc 206 releases the powder feeding roller 000, and the powder feeding roller 000 discharges from the rear along the discharge table 111. Then, the notch of the second control ring 405 moves to the moving rod frame 403, and the second spring 406 resumes controlling the moving rod frame 403 to move backward, and rotates the support block 401 to a state where it can support the powder feeding roller 000. Then, the feeding tray 305 cooperates with the guiding frame 307 to load the next powder feeding roller 000 onto the support block 401, that is, enter the processing operation of the next powder feeding roller 000, and so on in a cycle.
