Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing, and in particular to a feeding pretreatment device for metal sheet processing. Background Technology

[0002] During the metal sheet processing, the surface of the sheet often has residual oil from rolling, dust accumulated during storage, and debris generated during handling. If these impurities are not removed before processing, they will directly affect the quality of subsequent welding, painting, stamping and other processes. The current metal sheet feeding pretreatment devices have the following shortcomings: most devices can only clean one side of the sheet, requiring secondary processing of the other side, which is inefficient; the sheet is prone to displacement during transmission due to unstable clamping, resulting in misalignment of the cleaning position and affecting the cleaning effect; the contact pressure between the cleaning components and the sheet surface cannot be flexibly adjusted, which can easily lead to insufficient cleaning or excessive wear of the sheet for sheets of different thicknesses or with large differences in surface flatness. To address these issues, this invention presents a pre-treatment device that can simultaneously clean the upper and lower surfaces of the sheet material, provide stable clamping, and has strong adaptability.

Detailed Implementation

[0013] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0014] This application discloses a feeding pretreatment device for metal plate processing, including a processing frame 1, characterized in that; Two transmission modules 2 are symmetrically arranged on the processing frame 1. The two transmission modules 2 work together to clamp and transport the plate. The upper processing module 3 is set on the upper side of the processing frame 1 and is used to clean the upper surface of the board. The lower processing module 4 is located inside the processing frame 1 and is used to clean the lower surface of the board. Guide frames 11 are evenly arranged on the inner wall of the processing frame 1. The guide frames 11 are inclined along the direction of the plate entry and the surface is polished. They are used to guide the plate to enter the device accurately and avoid the end from colliding with the inner wall of the device and causing deformation. Two sponge rollers 12 are mounted on the inner wall of the processing frame 1 on the side away from the guide frame 11 via bearings. The sponge rollers 12 are made of high-density wear-resistant sponge. After cleaning, the plate passes between the sponge rollers 12 to further absorb the tiny impurities and moisture remaining on the surface, thereby improving the cleaning accuracy.

[0015] To achieve stable clamping and continuous conveying of the sheet metal, the transmission module 2 is designed as follows: the transmission module 2 includes a mounting groove on the side wall of the processing frame 1, with a rotating shaft symmetrically arranged along its length in the mounting groove. A transmission motor is mounted on the processing frame 1, and the output shaft of the transmission motor passes through the processing frame 1 and is connected to the rotating shaft. A sprocket 21 is mounted on the rotating shaft, and two sprockets 21 are connected by a chain 22. Abutment components 23 are evenly arranged on the chain 22. A pusher 24 for pushing the abutment components 23 is mounted on the inner wall of the processing frame 1, and the pusher 24 is located below the abutment components 23. A pressing component 25 is mounted on the inner wall of the processing frame 1, and the pressing component 25 is located above the abutment components 23.

[0016] The transmission motor drives the chain 22 to move in a cycle, causing the abutment component 23 to move synchronously; the pusher 24 pushes the abutment component 23 to move closer to the side of the board, and the abutment telescopic rod 234 extends and retracts adaptively according to the width of the board to ensure that the abutment pressing frame 235 fits tightly against the board; at the same time, the pressing component 25 applies downward pressure to form a three-dimensional clamping to prevent the board from shifting during transmission.

[0017] The abutment component 23 includes a connecting plate 231 disposed on the chain 22. The connecting plate 231 has a sliding hole, and a sliding rod 232 is movably disposed in the sliding hole. A spring is disposed between the sliding rod 232 and the connecting plate 231. An abutment frame 233 is disposed on the sliding rod 232. An abutment telescopic rod 234 is disposed on the abutment telescopic rod 234. An abutment pressing frame 235 is disposed on the abutment telescopic rod 234.

[0018] The pusher 24 includes a pusher cylinder 241 installed on the inner wall of the processing frame 1. A pusher frame 242 is provided on the pusher cylinder 241, and the two ends of the pusher frame 242 are arc structures.

[0019] The pressing assembly 25 includes a support spring rod 251 mounted on the processing frame 1, a support mounting bracket 252 mounted on the support spring rod 251, a pressing cylinder 253 mounted on the lower end of the support mounting bracket 252, and a pressing actuator 254 mounted on the pressing cylinder 253.

[0020] The specific working principle of the above technical solution is as follows; In the initial state, the connecting plate 231 is in the ready-to-work position along with the chain 22. The sliding rod 232, under the natural extension and contraction of the spring, drives the abutment frame 233 to the initial position away from the plate. The abutment extension rod 234 is in the retracted state, and the abutment pressing frame 235 is not in contact with the plate. The push cylinder 241 is in the retracted state, and the push frame 242 is located on the lower side of the abutment component 23, not in contact with the sliding rod 232. The support spring rod 251 is in the naturally extended state, the pressing cylinder 253 is retracted, and the pressing execution frame 254 is located on the upper side of the abutment component 23, not in contact with the plate.

[0021] When the metal sheet enters the processing frame 1 via the guide frame 11 and moves its front end between the abutment components 23, the push cylinder 241 extends, causing the push frame 242 to move upward and push the sliding rod 232 of the abutment component 23. Because the push frame 242 has rounded ends, it can smoothly contact the sliding rod 232. Under the pushing force of the push frame 242, the sliding rod 232 slides along the sliding hole of the connecting plate 231 towards the sheet, compressing the spring between it and the connecting plate 231. The spring stores force to prepare for subsequent reset. The sliding rod 232 drives the abutment frame 233 to move closer to the sheet at the same time. At this time, the abutment telescopic rod 234 extends adaptively according to the width of the sheet, so that the abutment pressing frame 235 fits tightly against the side of the sheet, completing the lateral clamping.

[0022] While the upper and lower clamping plates are laterally clamped by the abutment component 23, the pressing cylinder 253 of the pressing component 25 extends, driving the pressing actuator 254 to move downward until it contacts the upper end surface of the plate. The support spring rod 251 provides buffering during this process to prevent the pressing actuator 254 from damaging the plate due to excessive pressure. At the same time, the pressing actuator 254 and the abutment pressing frame 235 of the abutment component 23 form a clamping force in the vertical direction, which, together with the lateral clamping force, achieves three-dimensional fixation of the plate.

[0023] Using the above scheme, the transmission motor drives the rotating shaft to rotate, which in turn drives the abutment component 23 to move cyclically via the sprocket 21 and chain 22. Under the clamping action of the abutment pressing frame 235 and the pressing execution frame 254, the sheet material is conveyed forward synchronously with the chain 22. If there are slight undulations or minor differences in thickness on the surface of the sheet material, the spring sliding rod 232 of the abutment component 23 and the connecting plate 231, as well as the support spring rod 251 of the pressing component 25, will automatically adjust the clamping force through elastic extension and contraction, ensuring that the abutment pressing frame 235 and the pressing execution frame 254 always adhere to the sheet material, preventing slippage or displacement. The abutment telescopic rod 234 can compensate for minor changes in the width of the sheet material in real time, ensuring stable contact between the abutment pressing frame 235 and the side of the sheet material.

[0024] When the sheet material is conveyed to the end and disengaged from the abutment component 23: the push cylinder 241 retracts, the push frame 242 descends, releasing the thrust on the sliding rod 232; the sliding rod 232 resets under the elastic force of its own spring, driving the abutment frame 233, the abutment telescopic rod 234, and the abutment pressing frame 235 back to their initial positions; the pressing cylinder 253 retracts, and the pressing execution frame 254 rises and resets; the support spring rod 251 returns to its natural state, and the abutment component 23 moves cyclically with the chain 22, waiting for the next sheet material to enter, repeating the above-mentioned coordination process.

[0025] The upper processing module 3 includes a limiting slide groove formed on the processing frame 1. A limiting slide frame 31 is movably arranged in the limiting slide groove. A limiting spring rod 32 is arranged between the limiting slide frame 31 and the limiting slide groove. A lifting cylinder 33 is arranged on the limiting slide frame 31. A cleaning frame 34 is arranged on the lifting cylinder 33. Rotating shafts are evenly arranged in the cleaning frame 34 through bearings. A cleaning roller 35 is arranged on the rotating shaft. A gear 36 is arranged on the rotating shaft located outside the cleaning frame 34. An auxiliary spring rod 37 is arranged on the inner wall of the processing frame 1. An auxiliary plate 38 is installed at the lower end of the auxiliary spring rod 37. The lower end of the auxiliary plate 38 is provided with a rack that meshes with the gear 36, and the auxiliary plate 38 is slidably connected to the cleaning frame 34. The limiting sliding frame 31 slides in the limiting sliding groove of the processing frame 1, and the limiting spring rod 32 provides the restoring force. The lifting cylinder 33 extends and retracts to drive the cleaning frame 34 to move up and down, adjusts the distance between the cleaning roller 35 and the upper end surface of the plate, and adapts to plates of different thicknesses. The auxiliary spring rod 37 on the inner wall of the processing frame 1 pushes the auxiliary plate 38 downward, so that the rack at the lower end of the auxiliary plate 38 meshes with the gear 36 on the rotating shaft. When the cleaning frame 34 moves, the gear 36 rolls along the rack, driving the cleaning roller 35 to rotate and clean. A drive motor is mounted on the processing frame 1 via a motor mount. The output shaft of the drive motor passes through the processing frame 1 via a bearing. An elliptical block 39 is mounted on the output shaft of the drive motor. A drive groove is provided on the elliptical block 39 along its circumference. A drive slide rod 310 is provided on the limiting slide frame 31. A drive slider that cooperates with the drive groove is provided on the drive slide rod 310. The drive motor drives the elliptical block 39 to rotate. The drive groove of the elliptical block 39 cooperates with the drive slider of the drive slide rod 310 on the limit slide frame 31, causing the limit slide frame 31 to move back and forth, so that the cleaning frame 34 drives the cleaning roller 35 to move left and right while rotating, thereby enhancing the cleaning effect.

[0026] The lower processing module 4 includes rotating rods evenly arranged on the inner wall of the processing frame 1 via bearings. A cleaning roller 41 is slidably arranged on the rotating rod, and a cleaning brush is provided on the cleaning roller 41. A pulley 42 is provided on the rotating rod located on the outside of the processing frame 1. The pulleys 42 are connected to each other by a belt 43. A rotary motor is mounted on the processing frame 1 via a motor mount. The rotary motor is connected to one of the rotating rods via a coupling. The rotary motor drives one rotating rod to rotate via the coupling. The pulley 42 on the rotating rod drives the other rotating rods to rotate synchronously via the belt 43, so that the cleaning brush on the cleaning roller 41 on the rotating rod rotates and contacts the lower end surface of the plate for cleaning. A disc 44 is mounted on the rotating rod, and a return spring 45 is positioned between the disc 44 and the cleaning roller 41. A guide rod 46 is mounted on the end of the cleaning roller 41 away from the return spring 45. A guide ring 47 that cooperates with the guide rod 46 is mounted on the inner wall of the processing frame 1. The end face of the guide ring 47 that contacts the guide rod 46 has a concave-convex structure. The return spring 45 between the disc 44 on the rotating rod and the cleaning roller 41 applies a pushing force, causing the guide rod 46 of the cleaning roller 41 to press tightly against the guide ring 47 on the inner wall of the processing frame 1. Because the end face of the guide ring 47 has a concave-convex structure, when the cleaning roller 41 rotates, the guide rod 46 slides along the concave-convex surface, driving the cleaning roller 41 to reciprocate along the axial direction of the rotating rod, thus achieving comprehensive cleaning in conjunction with the rotation.

[0027] In the cleaning process of the board using the upper cleaning module 3 and the lower cleaning module 4, the upper cleaning module 3, through the rotation and reciprocating motion of the cleaning roller 35, can clean the upper surface of the board in multiple directions without dead angles, effectively removing dust, oil, debris and other impurities from the upper surface. The contact pressure between the cleaning roller 35 and the upper surface of the board can be adjusted by the lifting cylinder 33, and the auxiliary spring rod 37 ensures that the gear 36 and the rack are always meshed, ensuring a stable cleaning process and uniform cleaning effect. In the lower cleaning module 4, the cleaning roller 41 rotates while achieving axial reciprocating motion with the help of the guide rod 46 and the guide ring 47, which can thoroughly clean the impurities on the lower surface of the board, especially the residual dirt in the gaps or corners. The elasticity of the return spring 45 keeps the cleaning roller 41 in contact with the lower surface of the board, adapting to boards with different flatness, ensuring thorough cleaning and avoiding missed cleaning areas.
