Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example:

[0024] like Figures 1 to 6 As shown, this embodiment provides an automated loading and unloading device for a centerless grinder, which is installed on both ends of a placement trough 2. The placement trough 2 is located on a horizontal path leading to the grinding area of ​​the centerless grinder 1. It includes a loading assembly 3, a receiving trough 4, a turning trough 5, a receiving box 6, a pushing cylinder A7, and a pushing cylinder B8. Pushing cylinder A7 and pushing cylinder B8 are respectively provided on both ends of the placement trough 2. The receiving trough 4 and the turning trough 5 are provided between pushing cylinder A7 and the placement trough 2. Pushing cylinder A7 and pushing cylinder B8 are respectively provided on both ends of the placement trough 2. 8. The placement trough 2, receiving trough 4 and turning trough 5 are on the same straight line. The drive rods of the pushing cylinders A7 and B8 are facing the placement trough 2 and the end of the drive rod is provided with a push plate 9. The receiving trough 4 is located at the outlet end of the unloading assembly 3. The bottom of the receiving trough 4 is provided with a receiving box 6. The inlet end of the receiving box 6 is located on the side close to the turning trough 5. The bottom of the turning trough 5 is connected to the turning assembly 10 at the end away from the receiving box 6. Under the action of the turning assembly 10, the turning trough 5 can turn down to meet the inlet end of the receiving box 6.

[0025] The raw material falling into the receiving trough 4 is pushed onto the placement trough 2 via the steering trough 5 by the pushing cylinder A7. The processed raw material in the placement trough 2 is pushed onto the steering trough 5 by the pushing cylinder B8. The orientation of the steering trough 5 is changed by the steering component 10. Before the raw material is pushed away from the steering trough 5 by the pushing cylinder B8, the steering trough 5 rotates downward and connects to the inlet end of the receiving box 6 under the action of the steering component 10. The raw material pushed onto the steering trough 5 slides into the receiving box 6 along the steering trough 5, completing the loading and unloading of the centerless grinder. This reduces the manual intervention in the loading and unloading of the centerless grinder 1, reduces the burden on the workers, and improves production efficiency.

[0026] Specifically, the feeding assembly 3, the pushing cylinder A7, the pushing cylinder B8, the steering assembly 10, and the centerless grinder 1 are all electrically connected to the control console (not shown in the figure). The control console coordinates and controls the above devices to ensure the smooth feeding, grinding, and unloading of raw materials.

[0027] Furthermore, the feeding assembly 3 includes a storage hopper 11, a fixing ring 12, a rotating column 13, a motor A14, and a support frame 15. The support frame 15 is provided at the receiving groove 4, and the storage hopper 11 is provided on the top of the support frame 15. The fixing ring 12 is provided below the storage hopper 11 on the support frame 15. The rotating column 13 is rotatably connected to the fixing ring 12. The motor A14 is provided on the support frame 15. The drive rod of the motor A14 is coaxially connected to the rotating column 13. The fixing ring 12 is provided with a pair of symmetrical openings 16. The upper opening 16 is connected to the outlet end of the storage hopper 11, and the lower opening 16 is located above the receiving groove 4. The outer wall of the rotating column 13 is provided with several transition grooves 17 evenly distributed along the circumference. The shape of the transition groove 17 is composed of an outer cuboid and an inner semi-cylinder, and the height and width of the cuboid are equivalent to the diameter of the semi-cylinder.

[0028] By using the through-hole 16 of the fixed ring 12, the transition groove 17 on the rotating column 13, and the motor connected to the rotating column 13, the effect of timed material feeding into the receiving trough 4 is achieved. When the transition groove 17 is connected to the upper through-hole 16, the raw material in the storage hopper 11 falls into the transition groove 17. When the transition groove 17 is connected to the lower through-hole 16, the raw material in the transition groove 17 falls into the receiving trough 4. The rotating column 13 is rotated by the motor A14 to change the orientation of the transition groove 17.

[0029] Specifically, the transition trough 17 generally only accommodates a single raw material to prevent multiple raw materials from falling into the same transition trough 17 and to avoid overfeeding. The motor A14 drives the rotating column 13 to rotate in a fixed direction. The motor A14 can rotate slowly and evenly or start and stop according to the feeding time, so that the transition trough 17 containing raw materials only rotates to the opening 16 connected to the lower side when it is time to feed, so that the new raw material falls into the receiving trough 4 after the previous raw material has been processed and sent into the receiving box 6. The motor A14 and the rotating column 13 can be connected through a reduction gearbox.

[0030] Furthermore, the outlet end of the storage hopper 11 is provided with a pair of symmetrical sliding ports 18. The sliding ports 18 are horizontal, and a sliding plate 19 is slidably connected to the sliding ports 18. A handle 20 is rotatably connected to the outside of the storage hopper 11. Each end of the handle 20 is provided with a threaded rod 21 coaxial with the handle 20. The threads of the two threaded rods 21 are opposite to each other. The sliding direction of the sliding plate 19 is parallel to the threaded rods 21. A threaded sleeve 22 is provided on the outside of the sliding plate 19 and is threadedly connected to the threaded rods 21.

[0031] The sliding plate 19 can slide on the sliding port 18. The discharge width of the outlet end of the storage hopper 11 is controlled by adjusting the distance between the two sliding plates 19, limiting the discharge volume of the storage hopper 11 at one time. When the distance between the two sliding plates 19 is equal to the diameter of a single raw material, the storage hopper 11 can discharge only one raw material at a time, achieving orderly discharge from the storage hopper 11. Since the distance between the two sliding plates 19 is adjustable, it can be adjusted accordingly for raw materials of different diameters, expanding the scope of application. When adjusting the distance between the two sliding plates 19, the operator rotates the handle 20 to drive the threaded rod 21 to rotate. The rotating threaded rod 21 drives the threaded sleeve 22 connected by the thread to move along the axial direction of the threaded rod 21. The two threaded sleeves 22 move in opposite directions, and the moving threaded sleeves 22 drive the connected sliding plates 19 to move. The two sliding plates 19 move together or apart, thereby adjusting the distance between the sliding plates 19.

[0032] Furthermore, the transition groove 17 is provided with a support plate 23, and the first and last ends of the rotating column 13 are each provided with a sliding groove 24 leading to the transition groove 17. The sliding groove 24 is radially along the rotating column 13. The two ends of the support plate 23 are provided with sliders 25 that are slidably connected to the sliding grooves 24. The outer end of the slider 25 is provided with a threaded post 26, and a clamping nut 27 is threadedly connected to the threaded post 26. The outer end of the threaded post 26 is provided with a handle 28.

[0033] The shape of the transition groove 17 is fixed, but the dimensions of different raw materials vary. When the width (i.e., diameter) of the raw material is smaller than the width of the transition groove 17, more than one raw material may be placed in the transition groove 17, making it impossible to feed a single material into the transition groove 17. By adjusting the depth of the support plate 23 in the transition groove 17, the diameter of the raw material that the transition groove 17 can accommodate can be changed, thereby adapting to raw materials of different diameters and expanding the scope of application. The operator moves the support plate 23, which is indirectly connected to it, by moving the handle 28, thereby changing the depth of the support plate 23 in the transition groove 17. After the support plate 23 is moved to the required depth, the operator tightens the clamping nut 27 until it presses against the outer wall of the rotating column 13, thereby fixing the position of the slider 25 and the support plate 23 connected to the slider 25.

[0034] Specifically, the diameter of the raw material must exceed half the width of the transition groove 17. This is because when the diameter of the raw material is less than half the width of the transition groove 17, it is impossible to ensure that only a single raw material falls into the transition groove 17 by adjusting the depth of the support plate 23 within the transition groove 17. If the distance between the support plate 23 and the opening of the transition groove 17 is greater than the diameter of the raw material, the raw material cannot be completely placed into the transition groove 17. If the distance between the support plate 23 and the opening of the transition groove 17 is greater than the diameter of the raw material, multiple raw materials can be placed in the transition groove 17.

[0035] Furthermore, the steering assembly 10 includes a steering seat 29, a steering block 30, and a motor B31. The steering seat 29 is U-shaped, and the steering block 30 is rotatably connected to the inner side of the steering seat 29. The motor B31 is provided on the outer side of the steering seat 29. The drive rod of the motor B31 is coaxially connected to the rotating shaft of the steering block 30. The steering block 30 is connected to the bottom of the steering groove 5. A limiting block 32 for positioning the steering groove 5 is provided on the steering seat 29.

[0036] Motor B31 drives the connected steering block 30 to rotate, which in turn drives the connected steering groove 5 to rotate, thus changing the orientation of the steering groove 5. Before the push cylinder A7 pushes the raw material on the receiving groove 4 onto the placement groove 2, motor B31 rotates the steering groove 5 upwards via the steering block 30 until it aligns with the straight line of the receiving groove 4 and the placement groove 2. Before the push cylinder B8 pushes the processed raw material on the placement groove 2 onto the steering groove 5, motor B31 rotates the steering groove 5 downwards via the steering block 30 until it aligns with the inlet end of the receiving box 6. Limiting blocks 32 restrict the rotation range of the steering groove 5 by blocking it. The limiting blocks 32 are respectively set on both ends of the steering seat 29. When the steering groove 5 rotates to align with the receiving groove 4 or aligns with the inlet end of the receiving box 6, the bottom of the steering groove 5 abuts against the limiting blocks 32.

[0037] Furthermore, the bottom of the receiving trough 4 is provided with a buffer pad 33.

[0038] The impact of the raw material falling onto the receiving trough 4 is reduced by the buffer pad 33, thereby reducing the risk of damage to the raw material.

[0039] Furthermore, the receiving box 6 is equipped with a ramp 34 connecting the inlet end and the bottom.

[0040] The raw materials entering the receiving box 6 are allowed to roll down the inclined plane of the inclined platform 34 to avoid direct fall and reduce the risk of damage to the raw materials.

[0041] Working principle and usage process of this utility model:

[0042] During processing preparation, the staff adjusts and fixes the depth of the support plate 23 in the transition groove 17 according to the size of the raw material, and then puts the raw material to be processed into the storage hopper 11.

[0043] During processing, motor A14 drives rotating column 13 to rotate, and the raw material in the transition groove 17 that connects to the lower opening 16 falls into receiving groove 4. Cylinder A7 is pushed to extend push plate 9, and the raw material is pushed onto placement groove 2 after passing through turning groove 5. Then, centerless grinder 1 processes the raw material on placement groove 2. At the same time, motor B31 turns turning groove 5 down to the inlet end of receiving box 6 via turning block 30. After the raw material is processed, cylinder B8 pushes the raw material on placement groove 2 onto placement groove 2. The raw material slides down into receiving box 6 along placement groove 2. Finally, motor B31 turns turning groove 5 back up via turning block 30, and motor A14 drives turning column to release the next raw material. The above cycle is repeated until all raw materials are processed.

[0044] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
