[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] An efficient and labor-saving sponge charging roller grinding machine includes a frame. An automatic loading and unloading mechanism, a clamping mechanism, and a grinding mechanism are arranged on the frame. One side of the top surface of the frame is slidably connected with a sliding plate, and a driving mechanism for driving the sliding plate to slide is arranged on the frame. The grinding mechanism is installed on the other side of the top surface of the frame.

A plurality of groups of symmetric first positioning ports are arranged on the top surfaces of the two bearing plates. The top surface of the bearing plate close to the hopper is an inclined surface towards the first positioning port. The shaft rollers in the hopper are pushed out by the pushing part and slide onto the bearing plates, and the shaft rollers are sent to the clamping mechanism through the material receiving and feeding part. The shaft rollers are fixed by the clamping mechanism, and the shaft rollers on the clamping mechanism are ground by the grinding mechanism; the unloading mechanism includes a belt conveyor installed above the support frame and extending outward and a lifting part installed on the top of the support frame. The lifting part is located above the belt conveyor. The ground shaft rollers are grabbed by the lifting part and placed on the belt conveyor.

[0007] Preferably, a groove is formed in the top of the frame along the length direction, and first chutes in a V shape are formed on both sides of the top surface of the frame located in the groove. A first slider matching the first chute is connected to the bottom surface of the sliding plate, and a mounting block extending into the groove is further connected to the bottom surface of the sliding plate. The driving mechanism includes a rack connected to the mounting block, a first rotating shaft rotatably connected to the upper part of the frame, a gear connected to the first rotating shaft and meshing with the rack, a first motor mounted outside the frame, a transmission shaft drivingly connected to the first motor, a driving wheel connected to the transmission shaft, a driven wheel connected to the first rotating shaft, and a transmission belt connecting the driving wheel and the driven wheel. Both the rack and the gear are located in the groove.

[0008] In the above technical solution, when the first motor is started, it drives the first rotating shaft to rotate. Through the cooperation of the rack and the gear, the sliding plate is driven to slide on the frame, so as to drive the clamping mechanism to move on one side of the grinding mechanism to comprehensively grind the shaft roller.

[0009] Preferably, the hopper is inclined towards the sliding plate, and a through hole is formed at the position where the hopper is close to the sliding plate. The length of the through hole is smaller than the width of the hopper. The material pushing part includes a first cylinder mounted on the bottom surface of the hopper, a first fixing plate in an L shape connected to the telescopic end of the first cylinder, a first guide rail connected to the bottom surface of the first fixing plate, a first limiting block connected to the first cylinder, a push rod in a U shape connected to the top surface of the first fixing plate.

[0010] In the above technical solution, a plurality of shaft rollers are placed in the hopper. The shaft rollers slide along the hopper and are stacked in the hopper. Then, the first cylinder is controlled to extend, driving the first fixing plate to move upward, thereby driving the push rod to move upward to push the shaft roller upward and beyond the hopper. Since the top surface of the push rod is inclined towards the material receiving vertical plate, the shaft roller will slide along the inclined surface towards the material receiving vertical plate and then slide along the inclined surface on the material receiving vertical plate into the first positioning opening, thus realizing material pushing, that is, sending the shaft roller to the material receiving vertical plate of the feeding mechanism.

[0011] Preferably, the material receiving and feeding part includes a second cylinder mounted on the support frame, a second fixing plate in an L shape connected to the telescopic end of the second cylinder, a second guide rail connected to the bottom surface of the second fixing plate, a second limiting block connected above the second cylinder, a connecting plate mounted on the top surface of the second fixing plate, a third cylinder connected to one side of the connecting plate, and a lifting plate connected to the telescopic end of the third cylinder.

Second positioning openings matching the first positioning openings are formed on both sides of the lifting plate.

[0012] In the above technical solution, after the shaft roller reaches the material receiving vertical plate, the second cylinder contracts, driving the second fixing plate to move towards the hopper. When the second positioning port on the lifting plate aligns with the first positioning port, the third cylinder is controlled to extend, driving the lifting plate to rise, thereby lifting the roller on the material receiving vertical plate. Then, the second cylinder is controlled to extend, driving the lifting plate to move towards the clamping mechanism and align with it, so that the clamping mechanism can accurately clamp the shaft roller.

A fourth sliding groove is provided on the third limit block, and the third guide rail is slidably connected in the fourth sliding groove.

[0014] In the above technical solution, after the shaft roller is polished, the fourth cylinder extends, pushing the third fixing plate so that the cylinder jaw is located above the clamping mechanism. Then, the fifth cylinder is controlled to extend, driving the cylinder jaw to descend, thereby removing the shaft roller on the clamping mechanism. Then, the fourth cylinder is controlled to contract and the fifth cylinder is controlled to contract to place the shaft roller on the belt conveyor.

[0015] Preferably, the clamping mechanism includes a housing connected to one end of the sliding plate, a support seat connected to the other end of the sliding plate, a second rotating shaft rotatably connected to the housing, a third rotating shaft slidably connected to the support seat, a second motor installed on the housing and used to drive the second rotating shaft to rotate, and a sixth cylinder installed on the support seat.

[0016] In the above technical solution, when the shaft roller on the lifting plate aligns with the second rotating shaft and the third rotating shaft, the sixth cylinder is controlled to extend, pushing the third rotating shaft, and the third rotating shaft pushes the shaft roller on the lifting plate until the second rotating shaft and the third rotating shaft clamp the shaft roller. Then, the second motor is started to drive the second rotating shaft to rotate, which can drive the shaft roller to rotate.

[0017] Preferably, the grinding mechanism includes a lead screw displacement mechanism connected to the machine frame, a sliding seat installed on the lead screw displacement mechanism, a machine shell connected to the sliding seat, a fourth rotating shaft rotatably connected to the machine shell, a grinding wheel connected to the fourth rotating shaft, and a third motor installed on the machine shell and used to drive the fourth rotating shaft to rotate. The sliding seat can be driven to move towards the clamping mechanism through the lead screw displacement mechanism.

[0018] In the above technical solution, by driving the sliding seat to move through the lead screw displacement mechanism, the distance between the grinding wheel and the clamping mechanism can be adjusted. By operating the third motor to drive the fourth rotating shaft to rotate, the grinding wheel can be driven to rotate to grind the shaft roller on the clamping mechanism.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The hopper of the material storage mechanism is used to store the shaft rollers to be polished. The material pushing part lifts the shaft rollers in the hopper one by one. The lifted shaft rollers slide down to the material receiving vertical plate of the feeding mechanism. The shaft rollers on the material receiving vertical plate are sent to the clamping mechanism through the material receiving and feeding part. Then, the shaft rollers are fixed by the clamping mechanism and polished by the polishing mechanism. After the polishing is completed, the polished shaft rollers are grabbed and lifted by the lifting part, and finally placed on the belt conveyor and sent to the next process by the belt conveyor. The whole process does not require manual taking and placing of shaft rollers, realizing full-automatic feeding, polishing, discharging and feeding, and greatly improving the polishing efficiency.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0040] Embodiment 1

[0041] Please refer to Figure 1 and Figure 7, An efficient and labor-saving sponge charging roll grinding machine, comprising a frame 1, on which an automatic loading and unloading mechanism 2, a clamping mechanism 3 and a grinding mechanism 4 are provided. On one side of the top surface of the frame 1, a sliding plate 5 is slidably connected. On the frame 1, a driving mechanism 6 for driving the sliding plate to slide is provided. The grinding mechanism 4 is installed on the other side of the top surface of the frame 1. The automatic loading and unloading mechanism 2 is installed on the side of the sliding plate 5 away from the grinding mechanism 4. The clamping mechanism 3 is installed on the sliding plate 5 and is located between the automatic loading and unloading mechanism 2 and the grinding mechanism 4. The shaft roll is fixed by the clamping mechanism 3, and the shaft roll on the clamping mechanism 3 is ground by the grinding mechanism 4. The automatic loading and unloading mechanism 2 includes a support frame 21 connected to the sliding plate 5, a storage mechanism 22, a loading mechanism 23 and a unloading mechanism 24 connected to the support frame. Along the length direction, a groove 11 is opened at the top of the frame 1. On both sides of the top surface of the frame 1 where the groove is located, first chutes 12 in a V shape are opened. The bottom surface of the sliding plate 5 is connected with first sliders 51 matching the first chutes. The bottom surface of the sliding plate 5 is also connected with a mounting block 52 extending into the groove. The driving mechanism 6 includes a rack 61 connected to the mounting block, a first rotating shaft 62 rotatably connected to the upper part of the frame, a gear 63 connected to the first rotating shaft and meshing with the rack, a first motor 64 installed outside the frame, a transmission shaft drivingly connected to the first motor, a driving wheel 65 connected to the transmission shaft, a driven wheel 66 connected to the first rotating shaft, and a transmission belt 67 connecting the driving wheel and the driven wheel. The rack 61 and the gear 63 are both located in the groove 11. When the first motor 64 is started, through the cooperation of the driving wheel, the driven wheel and the transmission belt, the first rotating shaft 62 is driven to rotate. The first rotating shaft 62 drives the gear 63 to rotate. The gear 63 drives the sliding plate 5 to move linearly on the frame 1 through the cooperation with the rack 61, so that the shaft roll on the clamping mechanism 3 can be comprehensively ground by the grinding mechanism 4.

[0042] Such as Figure 4 , Figure 5As shown, the storage mechanism 22 includes a hopper 221 connected to the support frame and a material pushing part installed below the hopper; the hopper 221 is inclined towards the sliding plate 5 so that the shaft rollers roll into the hopper. A through hole is provided near the hopper 221 close to the sliding plate 5, and the length of the through hole is less than the width of the hopper 221 to prevent the shaft rollers from falling through the through hole; the material pushing part includes a first cylinder 222 installed on the bottom surface of the hopper 221, a first fixing plate 223 connected to the telescopic end of the first cylinder and in an L shape, a first guide rail 224 connected to the bottom surface of the first fixing plate, a first limiting block 225 connected to the first cylinder, and a push rod 226 connected to the top surface of the first fixing plate and in a U shape. A second sliding groove is provided on the first limiting block 225, and the first guide rail 224 is slidably connected in the second sliding groove. One end of the material receiving vertical plate 231 abuts against the hopper 221, and the top surface of the push rod 226 is inclined towards the material receiving vertical plate 231. The push rod 226 moves upward from the through hole by the extension of the first cylinder 22. After the shaft rollers are neatly arranged in the hopper, control the first cylinder 222 to extend, drive the push rod 226 to move upward, and push the shaft rollers upward through the push rod 226. Since the top surface of the push rod 226 is inclined towards the material receiving vertical plate 231, the pushed shaft rollers will slide on the material receiving vertical plate 231.

[0043] As Figure 2 , Figure 3As shown in the figure, the feeding mechanism 23 includes bearing plates 231 connected to both sides inside the support frame, and a material receiving and feeding part installed on the support frame and located between the two bearing plates. On the top surface of the two bearing plates 231, there are multiple groups of symmetric first positioning ports 232. The top surface of the bearing plate 231 near the hopper side is an inclined surface towards the first positioning port 232. The shaft rollers in the hopper 221 are pushed out by the pushing part and slide onto the bearing plate 231, and then the shaft rollers are sent to the clamping mechanism 3 by the material receiving and feeding part. Specifically, the material receiving and feeding part includes a second cylinder 233 installed on the support frame 21, a second fixing plate 234 connected to the telescopic end of the second cylinder and in an L shape, a second guide rail 235 connected to the bottom surface of the second fixing plate, a second limiting block 236 connected above the second cylinder, a connecting plate 237 installed on the top surface of the second fixing plate, a third cylinder 238 connected to one side of the connecting plate, and a lifting plate 239 connected to the telescopic end of the third cylinder. On the top surface of the second limiting block 236, there is a third sliding groove, and the second guide rail 235 is slidably connected in the third sliding groove. On both sides of the lifting plate 239, there are second positioning ports that cooperate with the first positioning ports 232. The top surface of the push rod 226 is inclined towards the bearing plate 231, so the shaft rollers after being pushed out will slide on the bearing plate 231. Since one end of the bearing plate is inclined towards the first positioning port, the shaft rollers will slide down along the bearing plate and enter the first positioning port 232. Then, control the second cylinder 233 to contract, driving the second fixing plate 234 to move towards the storage mechanism 22 until the second positioning port is aligned with the first positioning port 232. Then, control the third cylinder 238 to extend, driving the lifting plate 239 to rise, and lift the shaft rollers through the second positioning ports on the lifting plate 239. Then, control the second cylinder 233 to extend, pushing the shaft rollers between the clamping mechanisms 3 for the clamping mechanisms 3 to clamp. In order to align the second positioning ports on the lifting plate 239 with the first positioning ports 232 on the bearing plate 231, the working stroke of the second cylinder 233 can be set each time, or position sensors can be installed on the bearing plate 231 and the lifting plate 239.

The telescopic end of the sixth cylinder 36 is connected to the third rotating shaft 34. Positioning grooves are provided on the opposite surfaces of the second rotating shaft 33 and the third rotating shaft 34. When the shaft roller reaches between the second rotating shaft 33 and the third rotating shaft 34, control the sixth cylinder 36 to extend, push the third rotating shaft 34, so that both ends of the roller shaft are respectively inserted into the positioning grooves of the second rotating shaft 33 and the third rotating shaft 34, thereby completing the clamping of the shaft roller. In order to enable the shaft roller to accurately reach between the second rotating shaft 33 and the third rotating shaft 34, a position sensor can be provided on the lifting plate 239 and the housing 31 or the support base 32.

[0045] The grinding mechanism 4 includes a lead screw displacement mechanism connected to the frame, a sliding seat 41 installed on the lead screw displacement mechanism, a housing 42 connected to the sliding seat, a fourth rotating shaft rotatably connected to the housing, a grinding wheel 43 connected to the fourth rotating shaft, and a third motor 44 installed on the housing and used to drive the rotation of the fourth rotating shaft. The sliding seat 41 can be driven to move towards the clamping mechanism 3 through the lead screw displacement mechanism. The lead screw displacement mechanism is a device that drives the lead screw to rotate through a motor to achieve displacement, which is a prior art and will not be described in detail in this application. After the clamping mechanism clamps the shaft roller, drive the sliding seat 41 to move towards the shaft roller through the lead screw displacement mechanism, and then start the third motor 44 to drive the grinding wheel 43 to rotate, thereby grinding the shaft roller. At the same time, the driving mechanism drives the sliding plate to move, thereby comprehensively grinding the shaft roller.

[0046] The blanking mechanism 24 includes a belt conveyor 241 installed above the support frame and extending outward, and a lifting part installed at the top of the support frame. The lifting part is located above the belt conveyor 241, and grabs the shaft roller after grinding and places it on the belt conveyor 241. Specifically, the lifting part includes a fourth cylinder 242 installed at the top of the support frame, a third fixing plate 243 connected to the telescopic end of the fourth cylinder and in an L shape, a third guide rail 244 connected to the bottom surface of the third fixing plate, a third limit block 245 connected to the fourth cylinder, a fifth cylinder 246 connected to the third fixing plate, a mounting plate 247 connected to the telescopic end of the fifth cylinder, and a cylinder gripper 248 connected to the bottom surface of the mounting plate. A fourth chute is provided on the third limit block 245, and the third guide rail 244 is slidably connected in the fourth chute. When the shaft roller grinding is completed, control the fourth cylinder 242 to extend, push the third fixing plate 243, so that the cylinder gripper 248 is located above the ground shaft roller, and then control the fifth cylinder 246 to extend, drive the cylinder gripper 248 to descend, so as to remove the shaft roller on the clamping mechanism 3, and then control the fifth cylinder 246 to contract and the fourth cylinder 242 to contract, place the shaft roller on the belt conveyor 241, and convey the ground shaft roller to the next process through the belt conveyor. Among them, the cylinder gripper can adopt a finger cylinder, which will not be described in detail in this application.
