Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel plate polishing, in particular to a steel plate polishing production line. BACKGROUND

[0002] In the processing of material plates such as circuit boards, after the material plates are initially processed, they are usually temporarily stored on a steel plate. When the material plates need to be further processed, they are taken off the steel plate and sent to the next process for processing.

[0003] If the surface of the material plate has scratches or damage, it will affect the use of the material plate. Therefore, there is a higher requirement for the smoothness of the surface of the steel plate used to store the material plate. Therefore, the steel plate that has stored the material plate needs to have its surface polished before being used again.

[0004] However, the existing steel plate polishing is manually polished, that is, one side of the steel plate is polished first, and then the steel plate is flipped to polish the other side. This method usually has low polishing efficiency. SUMMARY

[0005] In order to improve the polishing efficiency of the steel plate, the present application provides a steel plate polishing production line.

[0006] The present application provides a steel plate polishing production line, which adopts the following technical scheme:

[0007] A steel plate polishing production line, comprising a machine box, a feeding port and a discharging port are respectively formed at both ends of the machine box, a polishing device is arranged near the feeding port in the machine box, the polishing device comprises an upper polishing roller, a lower polishing roller and a driving mechanism, the upper polishing roller is installed in the machine box in a direction perpendicular to the material conveying route, the lower polishing roller is installed in the machine box in a direction parallel to the upper polishing roller, and the lower polishing roller is located below the upper polishing roller, the surfaces of the upper polishing roller and the lower polishing roller are covered with a frosted layer, the width of the frosted layer is greater than the width of the steel plate, the upper polishing roller is used to polish the upper surface of the steel plate, the lower polishing roller is used to polish the lower surface of the steel plate, and the driving mechanism is installed in the machine box, and the driving mechanism is used to drive the upper polishing roller and the lower polishing roller to rotate.

[0008] By adopting the above technical scheme, the steel plate to be polished is sent into the machine box from the feeding port, and the driving mechanism in the polishing device drives the upper polishing roller and the lower polishing roller to polish the upper and lower surfaces of the steel plate, so that the mechanical polishing method is used instead of manual polishing, thereby facilitating the improvement of the polishing efficiency of the steel plate.

[0009] In one specific implementation, the driving mechanism includes a driving motor, a first driving gear and a second driving gear, the driving motor is installed in the cabinet, the first driving gear is coaxially installed on the output shaft of the driving motor, the output shaft of the driving motor is also coaxially connected with the upper polishing roller, the second driving gear is coaxially installed on the lower polishing roller, and the first driving gear is engaged with the second driving gear.

[0010] By adopting the above technical scheme, the first driving gear is driven to rotate by the driving motor, and the output shaft of the driving motor drives the upper polishing roller to rotate, so that the upper polishing roller is used to polish the upper surface of the steel plate. When the first driving gear rotates, the second driving gear also rotates with the first driving gear, thereby driving the lower polishing roller to rotate, so that the lower polishing roller is used to polish the lower surface of the steel plate.

[0011] In one specific implementation, the cabinet is also provided with a conveying device for conveying the steel plate from the polishing device to the discharge port, the conveying device includes a conveying roller and a driving source, the conveying roller is rotatably installed in the cabinet, the conveying roller is used to convey the steel plate, and the driving source is installed on the cabinet and used to drive the conveying roller to rotate.

[0012] By adopting the above technical scheme, after the steel plate is polished in the cabinet, the conveying device is used to convey the steel plate to the cleaning device and the drying device for further processing of the steel plate.

[0013] In one specific implementation, the cabinet is also provided with a cleaning device, the cleaning device includes an upper spray head, a lower spray head and a spray pipe, the spray pipe is installed in the cabinet close to the polishing device, one end of the spray pipe extends upward above the conveying roller, the other end of the spray pipe extends downward below the conveying roller, a liquid supply pipe is connected to the side wall of the spray pipe, the liquid supply pipe is used to communicate with an external water source, the upper spray head is installed on the side wall of the spray pipe above the conveying roller and faces the upper surface of the steel plate, and the lower spray head is installed on the side wall of the spray pipe below the conveying roller and faces the lower surface of the steel plate.

[0014] By adopting the above technical scheme, when the steel plate is polished, the liquid supply pipe is used to introduce cleaning liquid from the external water source into the spray pipe, so that the cleaning liquid is conveyed into the spray pipe and is used to flush the upper surface and the lower surface of the steel plate through the upper spray head and the lower spray head, thereby cleaning the debris on the surface of the steel plate and improving the smoothness of the steel plate.

[0015] In one specific implementation scheme, the machine casing is further provided with a drying device, which includes a drying fan, an upper air nozzle, and a lower air nozzle. A blower is installed near the discharge port inside the machine casing. The upper air nozzle and the lower air nozzle are both installed on the blower pipe, and the upper air nozzle is located above the lower air nozzle. The upper air nozzle is used to blow air onto the upper surface of the steel plate, and the lower air nozzle is used to blow air onto the lower surface of the steel plate. The blower pipe is connected to the drying fan through an air supply pipe.

[0016] By adopting the above technical solution, after the steel plate is washed, air is circulated into the air supply pipe by the drying fan, so that the upper and lower air nozzles blow air onto the upper and lower surfaces of the steel plate, thereby making it easier to keep the upper and lower surfaces of the steel plate dry.

[0017] In one specific implementation, a discharge device is provided at the discharge port of the steel plate. The discharge device includes a discharge mechanism, a stacking mechanism, and a control mechanism. The discharge mechanism includes a discharge frame, a discharge roller, and a drive component. The discharge frame is installed at the discharge port of the machine housing. The discharge roller is installed on the discharge frame and is used to transport the steel plate. The drive component is installed on the discharge frame and is used to drive the discharge roller to rotate. The stacking mechanism is installed at the end of the discharge frame away from the machine housing and is used to stack and store the steel plate. The control mechanism is installed on the discharge frame and is connected to the stacking mechanism.

[0018] By adopting the above technical solution, the steel plate, after being dried, is sent out of the machine casing and into the discharge mechanism. A drive unit rotates the discharge rollers, thus conveying the steel plate to the stacking mechanism for storage. When the stacking mechanism is full, a control mechanism limits the steel plates on the discharge rack and separates the stacking mechanism from the discharge rack, facilitating the replacement of the stacking structure and ensuring continuous storage of steel plates.

[0019] In one specific implementation, the stacking mechanism includes a stacking rack, a support plate, and a support spring. The stacking rack is installed at the end of the discharge rack away from the machine housing and is connected to the control mechanism. The support plate is slidably installed on the stacking rack in a vertical direction and is used to support the steel plate. The support plate is also connected to the control mechanism. The support spring is installed on the stacking rack, with one end connected to the bottom wall of the support plate and the other end connected to the support rack.

[0020] By adopting the above technical solution, when the steel plate is conveyed from the discharge rack to the stacking rack, the steel plate is located on the support plate and is continuously conveyed to the stacking rack by the discharge mechanism for stacking. The steel plate is then stacked and stored. The gravity of the steel plate causes the support plate to move downward and press the support spring. When the stacking rack is full of steel plates, the support plate limits the steel plate on the discharge rack through the control mechanism, thereby stopping the conveying of steel plates to the stacking rack, so as to facilitate the replacement of a new stacking rack.

[0021] In one specific implementation, the control mechanism includes a limiting component, a locking component, and a triggering component. The limiting component includes a limiting plate, which is slidably mounted vertically at the end of the discharge rack away from the machine housing. The limiting plate is used to limit the steel plate on the discharge rack. The locking component is mounted at the end of the discharge rack away from the machine housing and is connected to the limiting plate. The triggering component is mounted at the end of the discharge rack away from the machine housing, and both the locking component and the support plate are connected to the triggering component.

[0022] By adopting the above technical solution, when the steel plates in the stacking rack are full, the support plate drives the trigger component to move, thereby causing the trigger component to drive the limit plate to rise, thereby limiting the steel plates on the discharge rack and stopping the conveying of steel plates into the stacking rack. At the same time, the trigger component drives the locking component to move, causing the locking component to release the lock on the stacking rack, so as to facilitate the replacement of a new stacking rack.

[0023] In one specific implementation, the locking assembly includes a locking plate rotatably mounted on the end of the discharge rack away from the chassis, with one end of the locking plate extending away from the discharge rack and the other end of the locking plate bent upwards. The locking plate is used to position the stacking rack and is connected to a trigger.

[0024] By adopting the above technical solution, when steel plates are conveyed into the stacking rack, the stacking rack is locked by the locking plate, thereby reducing the movement of the stacking rack when the steel plates are conveyed into the stacking rack, so as to maintain the stable conveying of the steel plates.

[0025] In one specific implementation, the triggering element includes a trigger plate, a rotating plate, and a top block. The rotating plate is vertically mounted on the bottom wall of the locking plate, and the angle between the rotating plate and the locking plate is an acute angle. The trigger plate is slidably mounted vertically at the end of the discharge rack near the rotating plate, and the trigger plate abuts against the bottom wall of the support plate. A wedge is mounted on the side wall of the rotating plate near the trigger plate, and the side wall of the wedge abuts against the trigger plate. A first trigger spring is also mounted vertically on the discharge rack, one end of which is connected to the bottom wall of the trigger plate, and the other end is connected to the discharge rack. A second trigger spring is mounted horizontally on the discharge rack, one end of which is connected to the discharge rack, and the other end is connected to the side wall of the rotating plate away from the wedge. The top block is mounted on the side wall of the rotating plate away from the wedge, and the top block is connected to the bottom wall of the limiting plate.

[0026] By adopting the above technical solution, when the steel plate in the stacking rack reaches its maximum load capacity, the support plate presses down on the trigger plate, which in turn presses down on the wedge block and rotates the wedge block away from the trigger plate. This causes the rotating plate to rotate away from the stacking rack, which in turn causes the locking plate to rotate downwards until it separates from the stacking rack, thereby releasing the lock on the stacking rack. At the same time, the rotating plate causes the top block to push the limit plate upwards, thereby limiting the steel plate on the discharge rack and reducing the amount of steel plate that is continuously transported into the stacking rack.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. This application provides a grinding device to facilitate the grinding of steel plates by means of a mechanical grinding device, thereby replacing manual grinding and improving the grinding efficiency of steel plates.

[0029] 2. This application provides a stacking mechanism to facilitate the stacking of polished steel plates, thereby making the steel plates easier to store.

[0030] 3. This application provides a control mechanism to facilitate the locking and unlocking of the stacking rack, enabling the replacement of the stacking rack and thus ensuring continuous storage of steel plates. Attached Figure Description

[0044] Reference Figure 1 The steel plate to be processed is conveyed to the feeding device 6, which transports it from the inlet 11 into the machine housing 1. The conveying device 3 then transports the steel plate from the inlet 11 to the outlet 12. During this process, the steel plate is sequentially ground by the grinding device 2, cleaned of debris by the cleaning device 4, and dried by the drying device 5. After being conveyed out of the machine housing 1, the steel plate is discharged by the discharging device 7.

[0045] Reference Figure 2 The feeding device 6 includes a feeding frame 61, feeding rollers 62, and a power source. The feeding frame 61 is installed at the feed inlet 11 of the housing 1.

[0046] Reference Figure 3 The grinding device 2 includes an upper grinding roller 21, a lower grinding roller 22, and a drive mechanism 23. Multiple upper grinding rollers 21 are provided and are rotatably mounted on the inner wall of the housing 1 in a direction perpendicular to the material conveying direction. These multiple upper grinding rollers 21 are arranged along the length of the housing 1. Multiple lower grinding rollers 22 are also provided and are rotatably mounted inside the housing 1 in a direction parallel to the axis of the upper grinding rollers 21. The lower grinding rollers 22 are located below the upper grinding rollers 21, and these multiple lower grinding rollers 22 are arranged along the length of the housing 1.

[0047] Reference Figure 3The drive mechanism 23 includes a drive motor 231, a first drive gear 232, and a second drive gear 233. The drive motor 231 is fixedly mounted on the side wall of the housing 1. The output shaft of the drive motor 231 passes through the side wall of the housing 1 and extends into the housing 1.

Lower synchronous pulleys 236 are coaxially mounted on the ends of multiple lower grinding rollers 22 away from the drive motor 231, and the lower synchronous pulleys 236 are connected to each other by a lower synchronous belt 237.

[0048] Reference Figure 3 A drive motor 231 drives one of the upper grinding rollers 21 to rotate, which in turn drives the remaining upper grinding rollers 21 to rotate via an upper synchronous pulley 234 and an upper synchronous belt 235. Simultaneously, a first drive gear 232 drives a second drive gear 233 to rotate, which in turn drives one of the lower grinding rollers 22 to rotate, which in turn drives the remaining lower grinding rollers 22 to rotate via a lower synchronous pulley 236 and a lower synchronous belt 237. When the steel plate is conveyed between the upper grinding rollers 21 and the lower grinding rollers 22, the abrasive layers on the rotating surfaces of the upper and lower grinding rollers 21 and 22 polish the upper and lower surfaces of the steel plate.

[0052] Reference Figure 5 After grinding, the steel plate is conveyed onto the conveyor roller 32, which moves it towards the discharge port 12. As the steel plate passes the cleaning device 4, cleaning fluid is sprayed onto the upper surface of the steel plate through the upper spray head 41 and onto the lower surface through the lower spray head 42, thus rinsing the surface and removing debris. When the steel plate is conveyed to the drying device 5, the drying fan 51 blows air through the air duct 54 to the upper air nozzle 52 and the lower air nozzle 53, drying the surface of the steel plate.

[0055] Reference Figure 7 and Figure 8 The discharge device 7 also includes a control mechanism 73 for connecting the discharge mechanism 71 and the stacking mechanism 72. The control mechanism 73 includes a limiting component 731, a locking component 732, and a triggering component 733. The limiting component 731 includes a limiting plate 7311, which is slidably mounted on the discharge rack 711 at the end away from the housing 1 in a vertical direction. In the initial state, the limiting plate 7311 is located below the discharge roller 712. The locking component 732 includes a locking plate 7321, which is rotatably mounted on the end of the discharge rack 711 away from the housing 1. The end of the locking plate 7321 away from the discharge rack 711 extends toward the stacking rack 721, and the end of the locking plate 7321 near the stacking rack 721 is bent upward. A locking rod 724 is fixedly mounted on the side wall of the stacking rack 721 near the discharge rack 711, and the locking plate 7321 is engaged with the locking rod 724. The trigger component 733 is installed on the discharge rack 711, and the limit plate 7311 and the locking plate 7321 are both connected to the trigger component 733.

[0056] Reference Figure 7 and Figure 8The trigger assembly 733 includes a trigger plate 7331, a rotating plate 7332, and a top block 7334. The rotating plate 7332 is fixedly mounted vertically on the bottom wall of the locking plate 7321, and the angle between the rotating plate 7332 and the locking plate 7321 is an acute angle. A wedge block 7333 is fixedly mounted on the side wall of the rotating plate 7332 near the locking plate 7321, and the wedge block 7333 is located at the end of the rotating plate 7332 away from the locking plate 7321. The trigger plate 7331 is slidably mounted vertically on the end of the discharge rack 711 near the rotating plate 7332, and one end of the trigger plate 7331 extends toward the stacking rack 721. The top wall of the trigger plate 7331 abuts against the bottom wall of the support plate 722, and the trigger plate 7331 is used to abut against the wedge block 7333. A first trigger spring 7335 is vertically installed inside the discharge rack 711. One end of the first trigger spring 7335 abuts against the bottom wall of the trigger plate 7331, and the other end is connected to the discharge rack 711. A second trigger spring 7336 is horizontally installed inside the discharge rack 711 near the rotating plate 7332. One end of the second trigger spring 7336 abuts against the side wall of the rotating plate 7332 away from the wedge block 7333, and the other end is fixedly connected to the discharge rack 711. A top block 7334 is fixedly installed on the side wall of the rotating plate 7332 away from the wedge block 7333, and the top block 7334 is located at the end of the rotating plate 7332 near the locking plate 7321, and the top block 7334 is used to abut against the bottom wall of the limiting plate 7311.

[0057] Reference Figure 7 and Figure 9 When the steel plate is conveyed to the stacking rack 721 by the discharge roller 712, the steel plate falls onto the support plate 722 and, under the action of gravity, presses the support plate 722 downward, thereby compressing the support spring 723. As the steel plate is continuously conveyed into the stacking rack 721, the steel plate stacks on the support plate 722 and continuously drives the support plate 722 to move downward, thereby causing the support plate 722 to drive the trigger plate 7331 to move downward. When the steel plate in the stacking rack 721 reaches the maximum storage capacity, the support plate 722 drives the trigger plate 7331 to descend until it abuts the wedge block 7333, thereby pressing the wedge block 7333. 33 is pushed away from the stacker 721, thereby causing the rotating plate 7332 to rotate away from the stacker 721, thereby causing the locking plate 7321 to rotate downward until it separates from the locking rod 724, thus releasing the lock on the stacker 721. At the same time, the rotating plate 7332 causes the top block 7334 to rotate upward, thereby causing the limiting plate 7311 to move upward, so that the limiting plate 7311 is higher than the discharge roller 712, thereby limiting the steel plate on the discharge rack 711, so that the steel plate is no longer transported to the stacker 721, thus facilitating the replacement of the new stacker 721.

[0058] The working principle of this embodiment is as follows: The steel plate to be processed is conveyed to the loading rack 61, and the loading roller 62 conveys the steel plate from the feed port 11 to the machine box 1. The drive motor 231 drives the upper grinding roller 21 and the lower grinding roller 22 to rotate, thereby using the abrasive layer on the surface of the upper grinding roller 21 and the lower grinding roller 22 to grind the upper and lower surfaces of the steel plate. After grinding, the steel plate is conveyed to the cleaning device 4 by the conveying device 3. The upper spray head 41 and the lower spray head 42 spray cleaning liquid onto the upper and lower surfaces of the steel plate, respectively, thereby rinsing the surface of the steel plate. After rinsing, the steel plate is conveyed to the drying device 5, and the drying fan 51 blows air through the air pipe 54 to the upper air nozzle 52 and the lower air nozzle 53, thereby drying the surface of the steel plate.

[0059] After the steel plates are dried, they are conveyed out of the machine box 1 and transported to the stacking rack 721 by the discharge roller 712. The steel plates are then stacked on the support plate 722. As the steel plates are continuously transported to the stacking rack 721, the support plate 722 gradually moves downward due to the weight of the steel plates. This causes the trigger plate 7331 to move downward and press the first trigger spring 7335. When the stacking rack 721 reaches its maximum load capacity, the trigger plate 7331 abuts against the wedge block 7333 and pushes the wedge block 7333 away from the stacking rack 721. This causes the wedge block 7333 to drive the rotating plate 7332 to rotate away from the stacking rack 721 and press the second trigger spring 7336. This causes the locking plate 7321 to rotate downward, separating the locking plate 7321 from the locking rod 724, thereby releasing the lock on the stacking rack 721 so that the staff can replace the stacking rack 721. At the same time, the top block 7334 moves upward as the rotating plate 7332 rotates, thereby lifting the limiting plate 7311 upward, so that the limiting plate 7311 limits the steel plate on the discharge rack 711. At this time, the discharge motor 713 stops working, thereby stopping the discharge roller 712 from rotating, thus stopping the discharge of the steel plate.

[0060] When the stacker 721 is removed, the trigger plate 7331 moves upward to reset under the action of the first trigger spring 7335, and the rotating plate 7332 rotates to reset under the action of the second reset spring, so that the top block 7334 moves downward as the rotating plate 7332 rotates, thereby causing the limiting plate 7311 to fall back below the discharge roller 712. When the new stacking rack 721 is pushed to the end position of the discharge rack 711, the locking rod 724 abuts against the side wall of the bent end of the locking plate 7321, thereby pressing the locking plate 7321 downward, thereby driving the rotating plate 7332 to rotate and press the second trigger spring 7336. As the stacking rack 721 continues to move towards the discharge rack 711 until the support plate 722 is above the trigger plate 7331, after the locking rod 724 passes the bent end of the locking plate 7321, the rotating plate 7332 rotates and resets under the action of the second trigger spring 7336, thereby driving the locking plate 7321 to rotate upward and engage with the locking rod 724, thereby locking the stacking rack 721, which helps to keep the stacking rack 721 stable when the steel plate is transported into the stacking rack 721.

[0061] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
