Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0030] Example: An automatic loading and unloading mechanism for a powder feeding roller grinding machine, see 1- Figure 3 , including: a first support frame 101; a first motor 102 fixedly mounted on the first support frame 101; a rotating plate 103 rotatably mounted on the first support frame 101, the output end of the first motor 102 is fixed to the rotating plate 103; a grinding roller 104 rotatably mounted on the rotating plate 103; a second motor 105 fixedly mounted on the rotating plate 103, the output end of the second motor 105 is fixed to the grinding roller 104; a support block 401 rotatably mounted on the left and right sides of the rear portion of the first support frame 101, the support block 401 is used to support the powder feeding roller 000.

[0031] The first motor 102 drives the rotating plate 103 to rotate, which 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 grind the powder feeding roller 000.

[0032] See 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 of the second support frame 201; and a control unit group symmetrically arranged on the two mounting plates 202;

[0033] The control unit assembly includes: a rod portion provided on the mounting plate 202, a mounting ring seat 203 slidably mounted on the mounting plate 202 through the rod portion; a movable ring 204 slidably mounted on the mounting ring seat 203; a bearing 205 rotatably mounted on the movable ring 204; a stopper 206 fixedly mounted on the bearing 205; a first spring 207 fixedly mounted between the movable ring 204 and the mounting ring seat 203; a rotating cylinder 208 rotatably mounted on the mounting plate 202; a cross key connected to the rotating cylinder The transmission cylinder 209 on 208 is provided with a convex ring on the outside of the transmission cylinder 209, and a groove is provided in the mounting ring seat 203. The transmission cylinder 209 and the mounting ring seat 203 are rotated by the cooperation of the ring and the groove, 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 with the resistance plate 206. The contact surfaces of the transmission cylinder 209 and the resistance plate 206 are provided with grooves for increasing friction, so that the rotation of the transmission cylinder 209 can drive the resistance plate 206 to rotate.

[0034] Place the powder feeding roller 000 between the two control groups, control the two mounting ring seats 203 to move closer to the center, and the disc 206 and the transmission cylinder 209 follow and move toward the center. First, the disc 206 moves to contact the powder feeding roller 000, so that the two discs 206 fix the powder feeding roller 000, and then the mounting ring seat 203 continues to move toward the center. At this time, the positions of the disc 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, causing the disc 206 to move toward the center. 06 and the transmission cylinder 209 are reduced until they are in contact. Therefore, under the action of the grooves between the transmission cylinder 209 and the resistance plate 206, the rotating cylinder 208 rotates actively, and can control the rotation of the resistance plate 206 through the transmission cylinder 209, and then control the rotation of the powder feeding roller 000; on the contrary, when the two mounting ring seats 203 move to both sides and separate from each other, first, under the restoring action of the first spring 207, the resistance plate 206 and the transmission cylinder 209 are separated first, and then the resistance plate 206 is separated from the powder feeding roller 000.

[0035] See Figure 1 、 Figure 2 、 Figure 7 and Figure 8 , further comprising: a charging box 301 fixedly mounted on the top of the second support frame 201, the bottom of the charging box 301 being inclined, and a discharge port for only a single powder feeding roller 000 to pass through being provided at the lowest position of the bottom thereof; a mounting shaft 302 rotatably mounted on the second support frame 201, the mounting shaft 302 being provided below the charging box 301; a third motor 303 fixedly mounted 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 mounted at both ends of the mounting shaft 302 04; a loading tray 305 fixedly mounted on the two fixed trays 304, the loading tray 305 is provided with a slot adapted to the powder feeding roller 000, the powder feeding roller 000 is placed between the slots, and the loading tray 305 is rotated to control the movement of the powder feeding roller 000; a mounting sleeve 306 fixedly mounted on the bottom of the charging box 301, the mounting sleeve 306 is sleeved on the outside of the mounting shaft 302; a material guide rack 307 fixedly mounted on both sides of the mounting sleeve 306, the material guide rack 307 is used to guide the powder feeding roller 000 from the loading tray 305 to the support block 401.

[0036] The third motor 303 is started to control the installation shaft 302 and the upper fixed plate 304 and the loading plate 305 to rotate. Figure 7 , both ends of the powder feeding roller 000 at the discharge port of the charging box 301 will first be supported by the loading tray 305, and when the loading tray 305 rotates, a relative displacement will occur with the powder feeding roller 000, until the loading tray 305 rotates the notch on it to the powder feeding roller 000, and then the powder feeding roller 000 can fall into the notch and leave the charging box 301. Therefore, the rotating loading tray 305 will then transport the powder feeding roller 000, and the powder feeding roller 000 in the charging box 301 will automatically adjust its position under the action of gravity, and move the next powder feeding roller 000 to the discharge port of the charging box 301 and be supported by the loading tray 305; see for details Figure 8 As the loading tray 305 rotates, the powder feeding roller 000 transported by the loading tray 305 will contact the guide frame 307, and the position of the groove on the loading tray 305 gradually moves downward, so that the powder feeding roller 000 is transferred to the guide frame 307 and supported by the guide frame 307. Under the guidance of the guide frame 307, the powder feeding roller 000 is moved to the support block 401, thereby realizing automatic loading of the powder feeding roller 000.

[0037] See Figure 1 、 Figure 2 and Figure 9, further comprising: a rack 211 fixedly mounted on the two mounting ring seats 203, the two racks 211 being slidably mounted on the other mounting ring seat 203 not located thereon to increase the movement 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, the first gear 213 being engaged with both the racks 211 to control the synchronous and opposite movement of the two racks 211; 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 plates 304, the first control ring 215 being provided with a notch, an inclined surface being provided on the end of the notch of the first control ring 215, and the inclined surfaces of the two first control rings 215 being symmetrically arranged; and a protrusion 216 fixedly mounted on the two mounting ring seats 203, the protrusion 216 being engaged with the inclined surface of 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 inward.

[0038] When the mounting shaft 302 controls the rotation of the first control ring 215, the inclined surface on the first control ring 215 will control the two mounting ring seats 203 to move inward by squeezing the protrusion 216, so that the plate 206 fixes the powder feeding roller 000. After the movement is completed, the mounting ring seat 203 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 full circle, so that the notch on it moves to the protrusion 216, then the protrusion 216 is no longer restricted by the first control ring 215, the torsion spring 214 recovers and reverses the first gear 213, and the two mounting ring seats 203 are controlled to move to both sides and separate from each other through the rack 211 transmission.

[0039] See Figure 1 、 Figure 2 and Figure 12 , and also includes: a connecting shaft 221 rotatably mounted on the right mounting plate 202; a transmission belt set 222 installed between the connecting shaft 221 and the right rotating cylinder 208; a second gear 223 fixedly mounted on the connecting shaft 221 and the mounting shaft 302 respectively, the two second gears 223 are meshed, and there is a size difference between the two second gears 223, so that the mounting shaft 302 can accelerate the rotation of the transmission rotating cylinder 208.

[0040] See Figure 1 、 Figure 2 and Figure 10, also includes: a mounting bracket 402 fixedly mounted on the left and right sides of the first support bracket 101; a mobile rod bracket 403 slidably mounted on the two mounting brackets 402; a connecting slot plate 404 fixedly mounted on the two support blocks 401, each connecting slot plate 404 being slidably mounted with each mobile rod bracket 403 through the slots thereon; a second control ring 405 fixedly mounted on the fixed plate 304, a notch being provided on the second control ring 405, and an inclined surface being provided on the end of the second control ring 405 at the notch, the inclined surface of the second control ring 405 being able to cooperate with the mobile rod bracket 403, so that when the second control ring 405 rotates, it can control the mobile rod bracket 403 to move forward; a second spring 406 fixedly mounted between the mobile rod bracket 403 and the mounting bracket 402.

[0041] When the mounting shaft 302 controls the second control ring 405 to rotate, the second control ring 405 controls the moving rod frame 403 to move forward, thereby moving the lower end of the connecting slot plate 404 forward, and then rotating the connecting slot plate 404 to rotate the support block 401, so that the support block 401 no longer supports the powder feeding roller 000, thereby realizing automatic unloading of the powder feeding roller 000; the second control ring 405 will continue to control the support block 401, so that the support block 401 remains in a state of not supporting the powder feeding roller 000, until the second control ring 405 rotates nearly a full circle, so that the notch on its upper portion moves to the moving rod frame 403, and the second spring 406 resets the moving rod frame 403 backward, rotating the support block 401 to a state where it can support the powder feeding roller 000.

[0042] See Figure 11 , among the three features of the loading tray 305 and its upper notch, the first control ring 215 and its upper notch, and the second control ring 405 and its upper notch, the range of the notch of the first control ring 215 is larger than the range of the notch of the loading tray 305, and the range of the notch of the second control ring 405 is staggered with the range of the notch of the first control ring 215, so that when the mounting shaft 302 rotates, the cycle sequence of the 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 loaded onto the support block 401 - the two mounting ring seats 203 are controlled to move toward the center - 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 to 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, as in the above cycle.

[0043] See Figure 1 、 Figure 2 and Figure 13, and also includes: a discharge table 111 fixedly installed between the first support frame 101 and the second support frame 201, the discharge table 111 is arranged to be arc-shaped and inclined, and the highest point thereof is located below the support block 401; a guide plate 112 fixedly installed on the discharge table 111, the guide plate 112 is arranged on the other side of the highest point on the discharge table 111, and the guide plate 112 is arranged below the grinding roller 104.

[0044] During the process of grinding the powder feeding roller 000 by the grinding roller 104, the generated debris will be discharged forward along the guide plate 112 after falling, and 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 platform 111. In this way, when the powder feeding roller 000 is collected uniformly after processing, it is not easy for it to be stained with too much grinding debris, thereby reducing the trouble of subsequent processing.

[0045] In summary, the complete polishing process of this organization is:

[0046] An appropriate amount of powder feeding roller 000 to be ground is added to the loading box 301, and the third motor 303 is started to control the installation shaft 302 and the rotating cylinder 208 on the right to rotate. During the rotation of the installation shaft 302, the powder feeding roller 000 will be sequentially loaded onto the support block 401 by the loading plate 305 and the guide rack 307. Subsequently, the inclined surface on the first control ring 215 rotates to contact the protrusion 216, and the installation ring seat 203 is controlled to move inward, so that the plate 206 is fixed to the powder feeding roller 000 on the support block 401. And make the transmission cylinder 209 contact with the plate 206, then the rotating cylinder 208 rotating on the right can control the powder feeding roller 000 to rotate, and the rotating cylinder 208 on the left follows the rotation; after the plate 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, the first motor 102 and the second motor 1 05 is started, and the rotating grinding roller 104 is moved to contact with the powder feeding roller 000. After contact, the first motor 102 is turned off. At this time, the grinding roller 104 can evenly grind the powder feeding roller 000; after completing the grinding work, the first motor 102 is operated again to control the grinding roller 104 to move away. After completion, the first motor 102 and the second motor 105 are turned off; finally, when the fixed disk 304 rotates nearly a full circle, the notch of the first control ring 215 first moves to the protrusion 216, so that the mounting ring seat 203 moves to the The two sides move, and the plate 206 releases the powder feeding roller 000, so that the powder feeding roller 000 is discharged from the rear along the discharge platform 111. Then the gap of the second control ring 405 moves to the movable rod frame 403, and the second spring 406 restores the control of the movable 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 loading plate 305 cooperates with the guide frame 307 to load the next powder feeding roller 000 onto the support block 401, and then enters the next round of processing operation of the powder feeding roller 000, and the cycle continues.
