Description

Technical Field

[0001] This invention relates to the field of sheet metal production and processing technology, and in particular to a double-sided sanding device for sheet metal production and processing. Background Technology

[0002] In the production and processing of sheet materials, the sanding process plays a crucial role in achieving surface smoothness and roughness control, directly affecting the dimensional accuracy and surface quality of the finished sheet. Current double-sided sanding equipment typically employs sanding components arranged vertically, coupled with a conveyor structure to achieve continuous feeding of the sheet, thereby completing the synchronous processing of the upper and lower surfaces.

[0003] In actual processing, resin-containing sheets produce molten resin debris after cutting. This debris, once cooled and solidified, easily adheres to the conveyor structure and abrasive belt surface, gradually forming clumps and accumulating as processing time increases. This alters the cutting state of the abrasive belt surface, leading to a decrease in the uniformity of the processed surface. Conventional cleaning methods require stopping equipment operation, making it difficult to maintain a stable state for long-term continuous processing. Furthermore, for sheets of different thicknesses and widths, the existing device's limit guide structure requires disassembling and reassembling multiple fixed components for adjustment, hindering rapid specification switching. When deviation occurs during sheet feeding, the adaptation range of the correction structure is limited. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technology, such as the need to stop the equipment to clean resin clumps on the surface of the conveyor belt and sanding belt, the cumbersome process of adapting and adjusting different specifications of plates, and the limited range of plate feeding correction. Therefore, this invention proposes a double-sided sanding device for plate production and processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A double-sided sanding device for sheet metal production and processing includes a protective mechanism. The protective mechanism includes a side frame I and a side frame II, which are arranged in parallel.

It also includes three sets of conveying mechanisms, two of which are fixedly installed on the top of the lower support mechanism, and the other set of conveying mechanisms is fixedly installed on the top of the upper limit mechanism.

A lifting mechanism is provided on one side of the interior of the side frame II, and the lifting mechanism is used to adjust the height of the upper limit mechanism.

[0006] In one possible design, the protective mechanism further includes two door frames, which are respectively fixedly installed inside side frame I and side frame II.

Multiple bristles are fixedly installed on one side of the mounting horizontal plate.

[0009] In one possible design, a rotating shaft IV is rotatably connected to one side of a support frame located on the lower side and the upper side. The rotating shaft IV is fixedly connected to a conveyor roller shaft I. A rotating shaft III is rotatably connected to one side of the support frame. Gears are fixedly sleeved on the outer walls of both rotating shaft III and rotating shaft IV. The two gears mesh with each other. Rotating shaft II and two rotating shafts I rotatably pass through the interior of the frame and the limiting plate II.

The same double-acting screw passes through the internal threads of the two upper mounting plates. A handwheel is fixedly installed at one end of the double-acting screw, and the double-acting screw rotates through the sliding block.

[0011] In one possible design, the guiding mechanism further includes two limiting plates I. A rubber plate is fixedly installed on one side of each limiting plate I, and a slanted baffle is fixedly installed at one end of each limiting plate I. A rectangular block is fixedly installed on the top of each limiting plate I. The mechanism also includes two symmetrically arranged lower mounting plates. A rectangular mounting groove I is formed on the top of each lower mounting plate and the bottom of each upper mounting plate. A rotating rod is fixedly connected inside the rectangular mounting groove I. The outer walls of the two rotating rods are rotatably fitted with the same rotating connecting plate.

[0012] In one possible design, the upper limit mechanism further includes four T-shaped blocks, which are respectively fixedly installed on one side of side frame I and side frame II. Two symmetrically arranged T-shaped grooves are provided on both sides of the limiting plate II, and the T-shaped grooves are slidably connected to the T-shaped blocks. Two symmetrically arranged mounting cavities are provided inside the limiting plate II, and a limiting strip plate is slidably connected inside the mounting cavity.

A sealing handle is fixedly installed on one side of the sealing plate I.

[0013] In one possible design, the lower support mechanism includes a frame, which is fixedly installed between side frame II and side frame I, and dustproof nets are fixedly installed on both sides of the frame.

[0014] In one possible design, the lifting mechanism includes a lower horizontal plate and an upper horizontal plate, the upper horizontal plate being parallel to the lower horizontal plate and positioned above the lower horizontal plate. Both the lower and upper horizontal plates are fixedly installed on the inner wall of one side of the side frame II. A servo motor II is fixedly installed on the top of the upper horizontal plate. The output shaft of the servo motor II rotates through the upper horizontal plate and is fixedly installed with a one-way lead screw. A sliding plate is slidably connected inside the vertical hole I. One side of the sliding plate is fixedly connected to one side of the limiting plate II. An extension plate is fixedly installed on one side of the sliding plate, and a reinforcing plate is fixedly installed on one side of the extension plate. The one-way lead screw is threaded through the reinforcing plate. Two symmetrically arranged fixed side plates are fixedly installed on the inner wall of one side of the side frame II. A guide block is fixedly installed on one side of each fixed side plate, and the reinforcing plate is slidably connected between the two guide blocks.

[0015] In this application, the sheet material to be processed is conveyed into the device from the lower conveyor mechanism. The corresponding servo motor I is activated, and the output shaft of servo motor I drives the conveyor roller shaft II to rotate via a synchronous belt and synchronous pulley. The conveyor roller shaft II drives the circular roller to rotate, and the circular roller drives the conveyor belt to rotate cyclically along the support frame, providing conveying power for the sheet material feeding. Simultaneously, the rotating shaft I rotates synchronously with the polygonal roller, providing power input to the subsequent sanding assembly. The outer wall of the polygonal roller is provided with multiple continuous convex ridges. When the conveyor belt passes over the polygonal roller in a tensioned state, its flexible backing is subjected to high-frequency forced continuous bending-straightening alternating micro-deformation by the convex ridges.

[0016] When a conveyor belt coated with a mixture of resin (such as rosin) and wood chips that has melted and solidified at high temperature passes through the polygonal guide rollers at high speed under tension, the flexible backing of the conveyor belt is subjected to continuous alternating micro-deformation of "bending-straightening" by the high-frequency force of the raised ridges. Because the solidified resin clumps lack ductility, this high-frequency physical folding creates micro-cracks at the interface between the resin layer and the sand particles, forcing them to rigidly peel off and break. Furthermore, as the board passes over the top of the support plate, it pushes the support plate downwards. The support plate compresses the compression spring I, causing the sealing plates II on both sides below and the mounting cross plate to slide up and down. The bristles on the mounting cross plate, under the elastic force of the compression spring I, remain in contact with the outer surface of the conveyor belt, sweeping away the peeled debris and clumps. As the support plate moves downwards under the pressure of the board, the compression spring I is compressed, and its reverse elastic force continues to act on the support plate, causing the mounting cross plate and bristles to maintain stable contact with the surface of the conveyor belt. The cleaning effect is maintained even when the board thickness changes.

[0017] Furthermore, the power will drive the rotating shaft III through the gear via rotating shaft IV, rotating shaft III will drive the rotating shaft II through the synchronous belt and synchronous pulley, and rotating shaft II will drive the planer to rotate. At this time, there are limiters on both the upper and lower sides of the board by the conveyor belt to ensure its stability. Then, the synchronous belt and synchronous pulley will drive one of the rotating shafts I to rotate, thereby driving the sanding belt to rotate through the rotating roller to realize the sanding process. When the board moves to the top of the other conveyor belt, its top will be sanded, thus realizing the double-sided sanding operation. Furthermore, the distance between the frame and the limiting plate II can be adjusted according to the thickness of the sheet material. Specifically, the servo motor II is started, the output shaft of the servo motor II drives the one-way screw to rotate, the one-way screw drives the reinforcing plate to move up and down, the reinforcing plate drives the extension plate and the sliding plate to move up and down, the sliding plate drives the internal limiting plate II to move up and down, and the distance between the limiting plate II and the frame is adjusted to adapt to the size of the sheet material. The setting of T-blocks and T-slots ensures the stability of the movement of the limiting plate II. When the plate is fed into the device, if the plate deviates, it will first contact the inclined baffle on one side. The inclined baffle and the arc surface of the rubber plate will abut against each other. If the friction is small, the plate can be reset. If the friction is large, the two limiting plates I will form a parallelogram through the connection of the fixed outer cylinder and the sliding inner rod. The gap between the two limiting plates I remains unchanged. At the same time, the two rotating connecting plates can be rotated. After the rotating connecting plates rotate, the lifting horizontal plate will be lowered. The lifting horizontal plate will squeeze and compress the spring II. When the width of the sheet material changes and needs to be adapted, one side of the door panel can be opened. By turning the handwheel, the handwheel drives the double-acting screw to rotate. The double-acting screw causes the two upper mounting plates to move closer or further apart, and in conjunction with this, the sliding block is unscrewed, releasing the braking state of the sliding inner rod and the fixed outer cylinder. The sliding inner rod then moves inside the fixed outer cylinder, thereby adjusting the distance between the two rotating connecting plates to accommodate sheet materials of different sizes and ensure that they do not shift.

[0018] Beneficial effects: The conveyor mechanism is equipped with polygonal rollers. During the conveyor belt transmission, the contours of the polygonal rollers undergo continuous alternating bending and straightening micro-deformation. This causes the solidified resin clumps on the conveyor belt surface to develop micro-cracks and peel off under repeated deformation. The support top plate can adaptively float under the elastic force of compression spring I, driving the bristles on the mounting plate to maintain stable contact with the conveyor belt surface, thoroughly sweeping off the peeled debris. Resin clumps on the conveyor belt surface can be removed without stopping the equipment, maintaining a flat and stable conveyor surface and indirectly ensuring the uniformity of the sanding surface. As the sanding belt circulates with the rotating rollers, the surface can be cleaned by the matching fixed bristles. Combined with the self-cleaning structure of the conveyor belt, the entire machine can be cleaned without stopping the machine, ensuring continuous and stable processing. The heat dissipation holes at the bottom of the rectangular cavity can promptly dissipate the heat generated by the servo motor I, ensuring the stability of the drive components during long-term operation.

[0019] The three sets of conveying mechanisms are arranged in an alternating manner. The power is driven synchronously by gear meshing to drive the planer and sanding belt. During the feeding process of the plate, the planing and sanding of the upper and lower surfaces can be completed in sequence. During the processing stage, the plate is clamped and limited by the upper and lower conveyor belts, and the feeding state is stable, which can effectively reduce the probability of plate movement and ensure the accuracy and uniformity of the processed surface.

[0020] The lifting mechanism is driven by a servo motor II to rotate a one-way lead screw, which in turn moves the sliding plate and the upper limit mechanism vertically. The distance between the upper limit mechanism and the lower support mechanism can be quickly adjusted to adapt to the processing requirements of plates of different thicknesses. The sliding cooperation between the T-block and the T-slot can constrain the movement path of the limit plate II, ensuring the smoothness of the lifting process of the upper limit mechanism and avoiding deviation and jamming.

[0021] The guiding mechanism can correct and guide the feeding plate. The inclined baffle and rubber plate can guide the deviated plate back to the preset feeding path. When the lateral force of the plate is large, the limit plate I can drive the lifting horizontal plate to float vertically by rotating the connecting plate to avoid the plate and the guiding structure from getting stuck. By rotating the double screw by handwheel, the distance between the two mounting plates on both sides can be adjusted. With the telescopic structure of the fixed outer cylinder and the sliding inner rod, it can quickly adapt to plates of different widths. The adjustment process does not require disassembling the main structure.

[0022] The protective mechanism forms a relatively enclosed processing space by enclosing the side frame I, side frame II and door panel, which can reduce the outward spread of debris during processing; the dustproof nets set on both sides of the frame can block the leakage of debris while ensuring internal ventilation; the horizontal holes, vertical holes I and II provide corresponding operating space for the installation and adjustment of the conveying mechanism, lifting mechanism and guiding mechanism, respectively, taking into account both protective performance and convenient adjustment.

[0023] The upper limit mechanism is equipped with a sliding sealing plate I. The sealing plate I can be slid out along the mounting cavity via the limit strip plate, allowing for the inspection and maintenance of the internal sand-cutting components without disassembling the overall frame, making daily maintenance more convenient.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] In one embodiment: Refer to Figure 1-12A double-sided sanding device for sheet metal production includes a protective mechanism 1. The protective mechanism 1 includes side frames I 101 and II 108, which are arranged in parallel. A common lower support mechanism 5 is fixedly installed below the sides of side frames I 101 and II 108 that are close to each other. A common upper limit mechanism 4 is slidably connected between side frames I 101 and II 108, located above the lower support mechanism 5. The device also includes three sets of conveying mechanisms 2, two of which are fixedly installed on top of the lower support mechanism 5, and the other set is fixedly installed on top of the upper limit mechanism 4. The three sets of conveying mechanisms 2 are arranged alternately. A guide mechanism 3 is provided on one side of the bottom of the upper limit mechanism 4 to guide the sheet metal. A lifting mechanism 6 is provided on one side inside side frame II 108 to adjust the height of the upper limit mechanism 4.

[0028] Furthermore, the protective mechanism 1 also includes two door frames 105, which are respectively fixedly installed inside side frame I 101 and side frame II 108. Multiple door panels 103 are fixedly installed inside the door frames 105. A door handle 102 is fixedly installed on one side of each door panel 103. A clearance horizontal hole 104 is provided inside side frame I 101 to allow space for the conveying mechanism 2. A vertical hole I 106 and a vertical hole II 107 are provided on one side of side frame II 108. The vertical hole II 107 is used in conjunction with the guide mechanism 3, and the vertical hole I 106 is used in conjunction with the lifting mechanism 6. Preferably, the door panel 103 is made of cold-rolled steel plate, which can effectively prevent the outward diffusion of debris generated during processing, while also possessing sufficient structural rigidity to support daily opening and closing operations.

[0029] Specifically, the conveying mechanism 2 includes a support frame 201. Conveying roller shaft II 224 and conveying roller shaft I 223 are rotatably connected inside the support frame 201. A circular roller 221 is fixedly sleeved on the outer wall of the conveying roller shaft II 224, and a polygonal roller 222 is fixedly sleeved on the outer wall of the conveying roller shaft I 223. The outer walls of the polygonal roller 222 and the circular roller 221 are together sleeved with the same conveyor belt 203. A rectangular cavity 227 and a strip cavity 225 are opened inside the support frame 201. One end of the conveying roller shaft II 224 extends into the interior of the strip cavity 225. A servo motor I 220 is fixedly installed inside the rectangular cavity 227. The output shaft of the servo motor I 220 extends into the interior of the strip cavity 225. The output shaft of the servo motor I 220 and the conveying roller shaft II 224 are connected by a synchronous belt and a synchronous pulley. A heat dissipation hole 226 is opened on the bottom inner wall of the rectangular cavity 227. After the servo motor I 220 starts, the output shaft drives the conveyor roller shaft II 224 to rotate through the synchronous belt and synchronous pulley. The conveyor roller shaft II 224 drives the circular roller 221 to rotate synchronously. The circular roller 221 drives the conveyor belt 203 to circulate along the contour of the support frame 201. During the transmission process, the conveyor belt 203 runs in contact with the outer contour of the polygonal roller 222. The flexible backing of the conveyor belt 203 undergoes continuous bending-straightening alternating micro-deformation with the facet of the polygonal roller 222. The resin clumps that have been cured on the surface of the conveyor belt 203 lack extensibility. Under the action of high-frequency physical deformation, micro-cracks will be generated at the interface between the resin layer and the sand particles, and gradually rigid peeling and breakage will occur. The self-peeling of the clumps on the surface of the conveyor belt is completed under the continuous operation of the equipment. The heat dissipation hole 226 can dissipate the heat generated by the operation of the servo motor I 220 in a timely manner and maintain the stable operating temperature of the drive components.

[0030] Furthermore, a vertical groove 217 is provided on one side of the top of the support frame 201. Sliding grooves 218 are provided on the inner walls of both sides of the vertical groove 217. A slider 216 is slidably installed inside the sliding groove 218. The same support top plate 213 is fixedly installed between the two sliders 216. Two compression springs I 215 are symmetrically arranged between the bottom of the support top plate 213 and the bottom of the vertical groove 217. A sealing plate II 212 and a mounting horizontal plate 211 are threadedly connected to the bottom sides of the support top plate 213 by fixing bolts I 214. Multiple bristles 219 are fixedly installed on one side of the mounting horizontal plate 211. When the plate passes the top of the support plate 213, it will push the support plate 213 to move downward along the vertical groove 217. The support plate 213 will drive the sliders 216 on both sides to slide synchronously along the sliding groove 218. At the same time, it will squeeze the compression spring I 215 and drive the sealing plate II 212 and the mounting plate 211 below to move downward synchronously. The reverse elastic force of the compression spring I 215 can keep the bristles 219 in contact with the surface of the conveyor belt 203, sweeping off the peeled debris and clumps. The cutting ability of the sand belt 202 can be restored without stopping the equipment, ensuring the continuous operation of the processing process.

[0031] Specifically, a rotating shaft IV 209 is rotatably connected to one side of a support frame 201 located on the lower and upper sides. The rotating shaft IV 209 is fixedly connected to the conveyor roller shaft I 223. A rotating shaft III 208 is rotatably connected to one side of the support frame 201. Gears 210 are fixedly sleeved on the outer walls of both rotating shafts III 208 and IV 209. The two gears 210 mesh with each other, and gear covers are fixedly installed on the outer sides of the two meshing gears 210. The gear covers are fixedly installed on the side walls of the support frame 201 to close the gear meshing area and prevent sand and debris from entering the transmission. In the machine frame 501 and the limiting plate Ⅱ401, there are rotating shafts Ⅱ207 and two rotating shafts Ⅰ206 rotatably passing through the interior. Rotating rollers 205 are fixedly sleeved on the outer walls of the two rotating shafts Ⅰ206. The same sanding belt 202 is drivenly sleeved on the outer walls of the two rotating rollers 205. The outer walls of rotating shafts Ⅱ207 and one of the rotating shafts Ⅰ206 are connected to synchronous pulleys of different diameters via synchronous belts. A planing blade 204 is fixedly sleeved on the outer wall of rotating shafts Ⅱ207, so that the sanding belt and the planing blade form a matching speed difference to adapt to the different process requirements of planing and sanding. When conveyor roller I 223 rotates, it drives rotating shaft IV 209 to rotate synchronously. Rotating shaft IV 209 drives rotating shaft III 208 to rotate in the opposite direction through two meshing gears 210. Rotating shaft III 208 drives rotating shaft II 207 to rotate through a synchronous belt and synchronous pulley. Rotating shaft II 207 drives planer 204 to complete the cutting action. At the same time, rotating shaft II 207 drives one of the rotating shafts I 206 to rotate through a synchronous belt and synchronous pulley. Rotating shaft I 206 drives sanding belt 202 to run in a cycle through rotating roller 205. The three sets of conveying mechanisms 2 are arranged in an alternating manner. During the feeding process, the plate passes through the planing and sanding components below and above in sequence to complete the planing and sanding of the upper and lower surfaces. During the processing, the plate is clamped and limited by the upper and lower conveyor belts 203, and the feeding state remains stable, which can effectively reduce the impact of plate movement on processing accuracy.

[0032] Furthermore, the guide mechanism 3 includes a lifting horizontal plate 301, and rectangular holes 407 are provided on both sides of the upper limit mechanism 4. The lifting horizontal plate 301 is slidably connected inside the rectangular holes 407. A sliding block 310 is fixedly installed at one end of the lifting horizontal plate 301, and the sliding block 310 is slidably connected inside the vertical hole II 107. Two compression springs II 307 are symmetrically arranged between the bottom of the lifting horizontal plate 301 and the bottom inner wall of the rectangular hole 407. The guide mechanism 3 also includes two upper mounting plates 302, and a T-shaped recess is provided on the top of the upper mounting plate 302. The groove 311, the T-shaped groove 311 is slidably connected to the lifting horizontal plate 301. The internal threads of the two upper mounting plates 302 are connected to the same double-acting screw 308. A handwheel 309 is fixedly installed at one end of the double-acting screw 308. The double-acting screw 308 rotates through the sliding block 310. A corrugated dustproof sleeve is fitted on the outside of the double-acting screw 308. The two ends of the corrugated dustproof sleeve are fixedly connected to the fixed baffle 303 and the upper mounting plate 302 on the corresponding side, respectively. It adapts to the movement of the upper mounting plate 302 and expands and contracts accordingly to prevent dust from entering the threaded mating surface of the double-acting screw 308.

[0033] Specifically, the guide mechanism 3 also includes two limiting plates I 306. A rubber plate 304 is fixedly installed on one side of the limiting plate I 306, and an inclined baffle 305 is fixedly installed on one end of the limiting plate I 306. A rectangular block 317 is fixedly installed on the top of the limiting plate I 306. The guide mechanism 3 also includes two symmetrically arranged lower mounting plates 319. A rectangular mounting groove I 313 is opened on the top of the lower mounting plate 319 and the bottom of the upper mounting plate 302. A rotating round rod 312 is fixedly connected inside the rectangular mounting groove I 313. The outer walls of the two rotating round rods 312 are rotatably fitted with the same rotating connecting plate 320. A rectangular mounting groove I 317 is opened at the bottom of the lower mounting plate 319. The rectangular mounting slot II 318 is used in conjunction with the rectangular block 317. Both sides of the lower mounting plate 319 are threaded with fixing bolts II 316, which are threaded to the rectangular block 317. A fixed outer cylinder 315 is fixedly installed on one side of the lower mounting plate 319. The same sliding inner rod 314 is slidably connected between the two fixed outer cylinders 315. A locking bolt 321 is threaded through one side of the fixed outer cylinder 315, and one end of the locking bolt 321 abuts against the sliding inner rod 314. Two symmetrically arranged fixed baffles 303 are fixedly installed at the bottom of the lifting horizontal plate 301. The fixed baffles 303 are rotatably connected to the bidirectional screw 308. When the plate feeding device deviates, the side of the plate first contacts the inclined baffle 305. The inclined baffle 305, together with the arc surface of the rubber plate 304, applies a lateral guiding force to the plate, causing the plate to return to the preset feeding path. When the lateral force on the plate is large, the two limit plates I 306 are kept parallel through the connection between the fixed outer cylinder 315 and the sliding inner rod 314, and synchronously drive the rotating connecting plate 320 to rotate around the rotating round rod 312. During the rotation of the rotating connecting plate 320, the lifting horizontal plate 301 slides downward along the rectangular hole 407. The lifting horizontal plate 301 squeezes and compresses the spring II 307, and the lateral impact force is buffered by vertical floating to avoid the plate from being rigidly stuck with the guide structure. When it is necessary to adapt to plates of different widths, turn the handwheel 309 to drive the double-acting screw 308 to rotate. The double-acting screw 308 drives the two upper mounting plates 302 to move closer or further apart along the lifting cross plate 301. At the same time, loosen the locking bolt 321 to release the braking state of the sliding inner rod 314 and the fixed outer cylinder 315. The sliding inner rod 314 can move telescopically inside the fixed outer cylinder 315 to adjust the distance between the two sets of guide structures to adapt to plates of different widths. After the adjustment is completed, tighten the locking bolt 321 to fix the position.

[0034] Furthermore, the upper limit mechanism 4 also includes four T-shaped blocks 408, which are respectively fixedly installed on one side of side frame I 101 and side frame II 108. Two symmetrically arranged T-shaped grooves 406 are provided on both sides of the limiting plate II 401, and the T-shaped grooves 406 are slidably connected to the T-shaped blocks 408. Two symmetrically arranged mounting cavities 402 are provided inside the limiting plate II 401, and a limiting strip plate 403 is slidably connected inside the mounting cavity 402. A sealing plate I 404 is fixedly installed at the bottom of the limiting strip plate 403, extending through to the bottom of the limiting plate II 401. A sealing handle 405 is fixedly installed on one side of the sealing plate I 404. Preferably, the T-shaped blocks 408 are made of alloy steel with a hardened surface, capable of withstanding lateral loads during vertical sliding, ensuring the stability of the lifting process of the limiting plate II 401 and preventing deviation or jamming. When the internal sand-cutting components need to be inspected, hold the sealing handle 405 and pull it down to drive the limit strip plate 403 to slide out along the mounting cavity 402, which will expose the internal inspection space. Routine maintenance work can be completed without disassembling the overall frame.

[0035] Specifically, the lower support mechanism 5 includes a frame 501, which is fixedly installed between side frame II 108 and side frame I 101. Dustproof nets 502 are fixedly installed on both sides of the frame 501. The dustproof nets 502 can ensure air circulation inside the device while preventing the debris generated during processing from drifting outward, thus maintaining the cleanliness of the surrounding environment of the processing area.

[0036] This application can be used in the field of sheet metal production and processing, or in other fields applicable to this application.

[0037] In another embodiment: Reference Figure 1-12A double-sided sanding device for sheet metal production and processing is used in the field of sheet metal production and processing. The structure of this embodiment is basically the same as the previous embodiment, except that: the lifting mechanism 6 includes a lower horizontal plate 601 and an upper horizontal plate 605. The upper horizontal plate 605 is arranged parallel to the lower horizontal plate 601 and is above the lower horizontal plate 601. Both the lower horizontal plate 601 and the upper horizontal plate 605 are fixedly installed on one side of the inner wall of the side frame II 108. A servo motor II 606 is fixedly installed on the top of the upper horizontal plate 605. The output shaft of the servo motor II 606 rotates through the upper horizontal plate 605 and is fixedly installed with a one-way screw 604. A flexible dust cover is sleeved on the outer side of the one-way screw 604 and the two guide blocks 607. The upper and lower ends of the dust cover are fixedly connected to the upper horizontal plate 605 and the reinforcing plate 608 respectively, covering the threaded screw and the guide sliding surface throughout to prevent dust from entering. A sliding plate 602 is slidably connected inside the vertical hole I 106. One side of the sliding plate 602 is fixedly connected to one side of the limiting plate II 401. An extension plate 603 is fixedly installed on one side of the sliding plate 602. A reinforcing plate 608 is fixedly installed on one side of the extension plate 603. The one-way screw 604 is threaded through the reinforcing plate 608. Two symmetrically arranged fixed side plates 609 are fixedly installed on the inner wall of one side of the side frame II 108. A guide block 607 is fixedly installed on one side of the fixed side plate 609. The reinforcing plate 608 is slidably connected between the two guide blocks 607. When the height of the upper limit mechanism 4 needs to be adjusted to accommodate plates of different thicknesses, the servo motor II 606 is started. The output shaft of the servo motor II 606 drives the one-way lead screw 604 to rotate. The one-way lead screw 604 drives the reinforcing plate 608 to move vertically through the threaded engagement. The reinforcing plate 608 drives the extension plate 603 and the sliding plate 602 to slide synchronously along the vertical hole I 106. The sliding plate 602 drives the limit plate II 401 to move up and down along the guide of the T-block 408, thereby adjusting the distance between the limit plate II 401 and the frame 501 to accommodate the processing requirements of plates of different thicknesses. The two guide blocks 607 can constrain the movement path of the reinforcing plate 608, further improving the stability of the lifting process.

[0038] The device is also equipped with a controller, which is electrically connected to servo motor I 220 and servo motor II 606 respectively. The controller can control the start, stop and output speed of servo motor I 220, adjust the feed speed of the plate, and control the forward and reverse rotation and running stroke of servo motor II 606 to complete the height adjustment of the upper limit mechanism 4, ensuring the matching of the running sequence of each component. During long-term operation, the device needs to be cleaned of debris and lubricated regularly at each transmission part and sliding part to ensure the smooth operation and structural durability of the device.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller, servo motor I220, and servo motor II606 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
