Description

Technical Field

[0001] This invention relates to the field of conveying technology, and in particular to a feeding device for processing sponge grinding blocks with visual inspection. Background Technology

[0002] Sponge abrasive blocks are a common polishing tool. Made from a sponge base and incorporating abrasive grains, they are block-shaped polishing parts with a fixed shape and a certain degree of hardness, suitable for handheld use or use with equipment. During processing, sponge abrasive blocks undergo multiple steps, including base cutting, abrasive grain attachment, shaping and curing, edge treatment, and inspection and sorting. A conveyor belt connects these processes, eliminating the need for long-distance manual transport, preventing process interruptions, and significantly improving processing efficiency.

[0003] When sponge grinding blocks fall during processing, their edges can easily cause wear on the conveyor belt. The impact force generated by the fall is concentrated at the contact point between the narrow edge of the grinding block and the conveyor belt, causing a sudden increase in local pressure. In addition, the processed sponge grinding blocks form relatively hard edges, and some edges still have processing debris, burrs, or abrasive particles. When they fall, the hard edges are like small blades or abrasives. In existing technologies, the surface layer of the conveyor belt is mostly made of flexible wear-resistant rubber or PVC, which is tough and cannot withstand local hard impacts and concentrated scraping. At the moment of contact, the edge of the grinding block will scratch and grind the surface of the conveyor belt. At best, it will scratch and damage the wear-resistant layer; at worst, it will cause surface damage. Moreover, when the conveyor belt is running continuously, the falling grinding blocks will also create dynamic impact and relative sliding, which is equivalent to hitting and scraping at the same time. If the frequency of falling is high, the edges of multiple grinding blocks will repeatedly impact the same area, which will not only cause rapid fatigue wear of the conveyor belt surface, but also cause the initial small damage to be repeatedly pulled and expanded by subsequent materials, thereby accelerating the overall wear of the conveyor belt and shortening its service life. Therefore, a feeding device with visual inspection for processing sponge grinding blocks is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a feeding device for processing sponge grinding blocks with visual inspection.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a feeding device for processing sponge grinding blocks with visual inspection, comprising a bracket, a conveyor belt mounted on the outer surface of the bracket via a power mechanism, a plurality of conveying protrusions arranged in a parallel array on the outer surface of the conveyor belt, a connecting frame fixedly mounted at the rear end of the outer surface of the bracket, a lifting mechanism provided on the rear surface of the connecting frame, a vertical plate connected to the lifting end of the lifting mechanism, a plurality of pallets arranged in a parallel array fixedly connected to the lower side of the vertical plate, side baffles fixedly connected to the edges of the pallets on both sides, two leak-proof plates respectively mounted by a rotating mechanism on the lower surface of the plurality of pallets, the leak-proof plates on both sides rotating synchronously and maintaining symmetry on both sides, a wide protrusion between every two pallets on the upper surface of the leak-proof plates, and a narrow protrusion at the adjacent edges of the upper surfaces of the leak-proof plates on both sides, a material guiding mechanism provided on one side of the bracket, and a camera module provided on the other side of the bracket; After the leak-proof plates on both sides rotate downwards, the tray moves down and enters between two adjacent conveyor ridges.

[0006] Preferably, the material guiding mechanism includes a support column fixedly installed on one side of the upper surface of the bracket. A feed plate is fixedly installed at the upper end of the support column. A guide plate is connected to the lower side of the feed plate. A gate is slidably installed on the side of the guide plate. An opening is formed through the side surface of the gate. A sealing plate is fixedly connected to the lower side of the guide plate. The sealing plate slides against the side baffle. A pushing block is fixedly installed on the side surface of the gate near the guide plate. A pushing surface is formed on the lower surface of the pushing block. The pushing block is located above the opening. The lower side of the gate contacts the upper side of the side baffle.

[0007] Preferably, a sleeve rail is fixedly connected to the front and rear edges of one side surface of the gate, and a vertical guide bar is fixedly connected to the front and rear surfaces of the guide plate. An anti-detachment strip is fixedly connected to one side end of the vertical guide bar, and the one side end of the vertical guide bar and the anti-detachment strip are slidably inserted into the inner side of the sleeve rail.

[0008] Preferably, the power mechanism includes a plurality of transmission rollers rotatably mounted on the inner side of the support, the conveyor belt being sleeved on the outer surface of the plurality of transmission rollers, and the output shaft of a drive motor being fixedly mounted at one end of the foremost transmission roller, the drive motor being fixedly mounted on the side surface of the support.

[0009] Preferably, the lifting mechanism includes a mounting base fixedly installed on the rear surface of the connecting frame. A lifting cylinder and a guide cylinder are fixedly inserted into the inner side of the mounting base. A lifting frame is fixedly installed at the telescopic end of the lifting cylinder. A guide rod is slidably inserted into the upper end of the guide cylinder. The upper end of the guide rod is fixedly connected to the lower surface of the lifting frame. The front end of the lifting frame is fixedly connected to the upper side of the vertical plate.

[0010] Preferably, the rotating mechanism includes a vertical bracket fixedly connected to the connecting frame, a T-shaped frame fixedly connected to the front surface of the vertical bracket, and rotating rods fixedly connected to the opposite sides of the two leak-proof plates. The rear end of the rotating rods rotates through the front surface of the T-shaped frame, and a synchronous transmission mechanism is provided at the rear end of the two rotating rods.

[0011] Preferably, the synchronous transmission mechanism includes a power rod that runs laterally through the side surface of the T-shaped frame. The power rod rotates with the T-shaped frame. Transmission gears are fixedly installed on both ends of the power rod and the rear end of the rotating rod, and the two transmission gears on the same side mesh with each other. One end of the power rod is fixedly connected to the output shaft of the brake motor, and the brake motor is fixedly installed on the front surface of the vertical connector.

[0012] Preferably, the wide and narrow convex strips are provided with beveled edges on both sides.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, sponge grinding blocks are assisted in being poured in by a feeding plate. They are discharged through the outlet at the guide plate and reach the surface of the pallet. Due to the presence of wide and narrow convex strips, the gaps between the pallets are filled, preventing the grinding blocks from getting stuck at corners and causing them to tilt. This ensures that the grinding blocks are placed flat on the surface of the pallet. When the camera module captures a large number of grinding blocks on the surface of the pallet, the brake motor is controlled to operate, the power rod rotates, and under the meshing transmission of the transmission gears, the two rotating rods rotate synchronously, and the pallets on both sides rotate downward. Then, the lifting cylinder is controlled to retract, driving the lifting frame, vertical plate, and pallet to move downward. After moving downward, the conveying convex strips pass through the gaps between adjacent pallets, making horizontal contact with the lower surface of the grinding blocks and conveying them forward. Since the edges of the grinding blocks do not contact the surfaces of the conveyor belt and the conveying convex strips during the contact process, no scratching problem occurs, extending the service life of the entire feeding device.

[0014] 2. In this invention, when the lifting cylinder retracts and the side baffle moves downward, it no longer supports the gate. Under the action of gravity, the gate moves downward, and the opening and the guide plate are misaligned at a certain height, blocking the grinding block and stopping the feeding. During this process, the pushing surface will contact and squeeze the grinding block, causing the grinding block to move and preventing the grinding block from getting stuck inside the opening during the downward movement. When the side baffle moves upward and resets, the gate moves upward again, and the opening opens to feed. Therefore, it has the function of automatically controlling the feeding and realizing the automated conveying of grinding blocks in batches. Attached Figure Description

Detailed Implementation

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figures 1-9The device shown is a feeding device for processing sponge grinding blocks with visual inspection. It includes a support 1, a conveyor belt 2 mounted on the outer surface of the support 1 via a power mechanism, and several conveying protrusions 32 arranged in a parallel array on the outer surface of the conveyor belt 2. A connecting frame 3 is fixedly mounted at the rear end of the outer surface of the support 1. A lifting mechanism is provided on the rear surface of the connecting frame 3. A vertical plate 14 is connected to the lifting end of the lifting mechanism. Several pallets 15 arranged in a parallel array are fixedly connected to the lower edge of the vertical plate 14. Side baffles 16 are fixedly connected to the edges of the two outermost pallets 15. Two leak-proof plates 10, each mounted via a rotating mechanism, are provided on the lower surface of the pallets 15. The leak plate 10 rotates synchronously and maintains symmetry on both sides. A wide protrusion 11 is provided on the upper surface of the leak-proof plate 10 and between each pair of support plates 15. Narrow protrusions 12 are provided on the upper surface of the leak-proof plates 10 on both sides and at their adjacent edges. A material guiding mechanism is provided on one side of the bracket 1, and a camera module 35 is provided on the other side of the bracket 1. The camera module 35 is composed of an industrial camera, a supplementary lighting unit, an image processing unit, and a signal transmission unit. It is existing technology. It should be noted that the camera module 35 is not responsible for high-precision identification (such as the size of the grinding block or defects). It only performs inventory monitoring and is suitable for batch feeding scenarios of sponge grinding block materials. The design focuses on stability and durability rather than complex functions.

[0019] After the two leak-proof plates 10 rotate downwards, the support plate 15 moves down and enters between two adjacent conveyor convex strips 32, at which point the state is as follows. Figure 8 , Figure 9 As shown.

[0020] like Figure 1 , Figure 4 , Figure 5 As shown, the material guiding mechanism includes a support column 31 fixedly installed on one side of the upper surface of the bracket 1. A feed plate 22 is fixedly installed at the upper end of the support column 31. A guide plate 23 is connected to the lower side of the feed plate 22. A gate 24 is slidably installed vertically on the side end of the guide plate 23. An opening 25 is formed through the side surface of the gate 24. A sealing plate 36 is fixedly connected to the lower edge of the guide plate 23. The sealing plate 36 slidably contacts the side baffle 16. A pushing block 26 is fixedly installed on the side surface of the gate 24 near the guide plate 23. A pushing surface 27 is formed on the lower surface of the pushing block 26, and the pushing block 26 is located above the opening 25. The lower edge of the gate 24 contacts the upper edge of the side baffle 16. The feed plate 22 facilitates the user to pour in the grinding blocks, and the retracted guide plate 23 guides the grinding blocks into the feed.

[0021] like Figure 6 , Figure 7As shown, a sleeve rail 28 is fixedly connected to the front and rear edges of one side surface of the gate 24, and a vertical guide bar 29 is fixedly connected to the front and rear surfaces of the guide plate 23, respectively. An anti-detachment strip 30 is fixedly connected to one end of the vertical guide bar 29, and the one end of the vertical guide bar 29 and the anti-detachment strip 30 slide together into the inner side of the sleeve rail 28. When the gate 24 moves up or down, the sleeve rail 28 will slide relative to the surfaces of the vertical guide bar 29 and the anti-detachment strip 30 to ensure the smooth movement of the gate 24.

[0022] like Figure 3 As shown, the power mechanism includes several transmission rollers 33 rotatably mounted inside the support 1. The conveyor belt 2 is sleeved on the outer surface of the transmission rollers 33. The output shaft of the drive motor 34 is fixedly mounted at one end of the foremost transmission roller 33. The drive motor 34 is fixedly mounted on the side surface of the support 1. When the drive motor 34 operates, it moves the conveyor belt 2 through the transmission rollers 33, thereby achieving the purpose of conveying the grinding blocks.

[0023] like Figure 3 As shown, the lifting mechanism includes a mounting base 21 fixedly installed on the rear surface of the connecting frame 3. A lifting cylinder 18 and a guide cylinder 19 are fixedly inserted into the inner side of the mounting base 21. A lifting frame 17 is fixedly installed at the telescopic end of the lifting cylinder 18. A guide rod 20 is slidably inserted into the upper end of the guide cylinder 19. The upper end of the guide rod 20 is fixedly connected to the lower surface of the lifting frame 17. The front end of the lifting frame 17 is fixedly connected to the upper edge of the vertical plate 14. During the telescopic process of the lifting cylinder 18, the guide rod 20 will move up and down relative to the guide cylinder 19, which improves the stability of the lifting frame 17 when it moves.

[0024] like Figure 3 As shown, the rotating mechanism includes a vertical bracket 4 fixedly connected to the connecting frame 3. A T-shaped bracket 6 is fixedly connected to the front surface of the vertical bracket 4. Rotating rods 7 are fixedly connected to the opposite sides of the two leak-proof plates 10. The rear ends of the rotating rods 7 rotate through the front surface of the T-shaped bracket 6. A synchronous transmission mechanism is provided at the rear ends of the two rotating rods 7. By controlling the synchronous rotation of the two rotating rods 7, the two leak-proof plates 10 are controlled to rotate downwards to open or upwards to close synchronously.

[0025] like Figure 3 As shown, the synchronous transmission mechanism includes a power rod 5 that runs transversely through the side surface of the T-shaped frame 6. The power rod 5 and the T-shaped frame 6 rotate relative to each other. Transmission gears 8 are fixedly installed on both ends of the power rod 5 and the rear end of the rotating rod 7, respectively. The two transmission gears 8 on the same side mesh with each other. One end of the power rod 5 is fixedly connected to the output shaft of the brake motor 9, and the brake motor 9 is fixedly installed on the front surface of the vertical bracket 4. When the brake motor 9 operates, the power rod 5 rotates, and under the action of the transmission gears 8, the rotating rods 7 on both sides rotate synchronously and maintain opposite rotation.

[0026] like Figure 1, Figure 2 As shown, the wide convex strip 11 and the narrow convex strip 12 are respectively provided with beveled edges 13 on both sides. This design ensures that the wide convex strip 11 and the narrow convex strip 12 will not be pushed and jammed with the support plate 15 when the leak-proof plate 10 is rotating, and the edges of adjacent leak-proof plates 10 will not be pushed.

[0027] During use, the user pours the sponge grinding blocks into the feed plate 22, which then exits through the outlet 25 at the guide plate 23 and onto the surface of the pallet 15. The presence of the wide ridge 11 and the narrow ridge 12 fills the gaps between the pallets 15, preventing the grinding blocks from getting stuck at corners and causing them to tilt. This ensures that the grinding blocks are placed flat on the surface of the pallet 15. When the camera module 35 captures a large number of grinding blocks on the surface of the pallet 15, the brake motor 9 is controlled to operate, and the power rod 5 rotates. Under the meshing transmission of the transmission gear 8, the two rotating rods 7 rotate synchronously, and the two pallets 15 on both sides rotate downward. Then, the lifting cylinder 18 is controlled to retract, causing the lifting frame 17, the vertical plate 14, and the pallet 15 to move downward. After moving downward, the conveyor ridge 32 passes through the gap between adjacent pallets 15, making horizontal contact with the lower surface of the grinding blocks and conveying them forward. Since the edges of the grinding blocks do not contact the surfaces of the conveyor belt 2 and the conveyor ridge 32 during the contact process, there is no scratching problem, thus extending the service life of the entire feeding device.

[0028] When the lifting cylinder 18 retracts, the side baffle 16 moves downward and no longer supports the gate 24. Under the action of gravity, the gate 24 moves downward, and the opening 25 and the guide plate 23 are misaligned, blocking the grinding block and stopping the feeding. During this process, the pushing surface 27 will contact and squeeze the grinding block, causing the grinding block to move and preventing the grinding block from getting stuck inside the opening 25 during the downward movement. When the side baffle 16 moves upward and resets, the gate 24 moves upward again, and the opening 25 opens to feed. After the grinding block falls onto the support plate 15, there is a phenomenon where the corner of the grinding block is between the adjacent support plates 15. At this time, the anti-leakage plate 10 is controlled to rotate and reset, and the wide convex strip 11 and the narrow convex strip 12 push the corner of the grinding block, causing the corner of the grinding block to be squeezed out and tilted unbalancedly, lying flat on the surface of the support plate 15.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
