Description

Technical Field

[0001] This invention relates to the field of sheet metal production technology, specifically to a grinding device and grinding method for sheet metal production. Background Technology

[0002] In the production of wood panels, sanding is a crucial process. Its main purpose is not limited to "edge sanding," but encompasses the comprehensive treatment of the wood surface and edges to improve the quality, aesthetics, and feasibility of subsequent processing of the final product. Sanding can effectively remove impurities and damage such as burrs, unevenness, roughness, wood fibers, glue residue, and pencil marks from the wood surface, making the surface smooth.

[0003] Authorization announcement number CN118404452B discloses a grinding device for processing wood panels. The invention describes that "the self-adjusting grinding mechanism set in this invention can grind all sides of the wood panel without dead angles, and only needs to be fixed once to achieve integrated grinding of all sides. No position and angle adjustment is required during the processing, resulting in high processing efficiency. It can grind the sides of wood panels with regular contours as well as irregularly shaped wood panels, and has strong versatility."

[0004] The current edge-grinding device for wood-based panel processing, when processing rectangular panels, first uses a conveying mechanism to move the first panel to a designated position, and then uses a center positioning mechanism and a clamping and fixing mechanism to position the panel. Next, a self-adjusting sanding mechanism grinds the sidewalls of the panel. Finally, the center positioning mechanism and clamping and fixing mechanism release the panel from its position, and the conveying mechanism moves the second panel to a designated position. This process not only makes it difficult to guarantee sanding accuracy, affecting the edge-grinding effect, but also takes time to position the panel, impacting edge-grinding efficiency. Therefore, a new edge-grinding device and method for panel production is proposed to solve these problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a grinding device and method for sheet metal production, which has advantages such as high-efficiency grinding. It solves the problems that not only is it difficult to guarantee grinding accuracy, which affects the grinding effect, but also that positioning the sheet metal takes time, which affects the grinding efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an edge grinding device for sheet metal production, comprising a conveyor belt, an adjustment mechanism, a guide mechanism, an edge grinding mechanism, and a limiting mechanism, wherein the adjustment mechanism is fixedly connected inside the conveyor belt, the guide mechanism is fixedly connected to the free end of the adjustment mechanism, the edge grinding mechanism is slidably connected inside the guide mechanism, and the limiting mechanism is fixedly connected above the conveyor belt.

[0007] Furthermore, the adjustment mechanism includes a chamber body, which is fixedly connected inside the conveyor belt. A dual-axis motor is fixedly installed on the inner bottom wall of the chamber body. Threaded rods are fixedly installed on both output ends of the dual-axis motor. The threads of the two threaded rods are in opposite directions. The sides of the two threaded rods away from the output ends of the dual-axis motor are rotatably connected to the inner side wall of the chamber body. Threaded sleeves are threadedly installed on the outside of each of the two threaded rods. Two adjusting rods are fixedly installed on the outside of each of the two threaded sleeves. The four adjusting rods are divided into two groups. Both groups of adjusting rods penetrate the chamber body and the conveyor belt and extend to both sides of the conveyor belt. Adjusting holes matching the adjusting rods are provided on the side wall of the chamber body.

[0008] Furthermore, the guiding mechanism includes two first frames, which are respectively fixedly connected to the top of two sets of adjusting rods. Guide plates are fixedly installed on the side walls of the two first frames, and multiple guide rollers are rotatably installed inside the two first frames.

[0009] Furthermore, the edge grinding mechanism includes multiple mounting brackets, which are divided into two groups. The two groups of mounting brackets are respectively fixedly connected to the bottom of two first frames. A first electric push rod is fixedly installed inside each of the two groups of mounting brackets. The output ends of the first electric push rods of both groups pass through the first frame and are fixedly installed on a second frame. A through hole matching the second frame is opened at the top of each of the two groups of second frames. A motor is fixedly installed at the top of each of the two groups of second frames. The output ends of the motors of both groups pass through the second frame and are fixedly installed on a transmission roller. The bottom of the two groups of transmission rollers is rotatably connected to the inner bottom wall of the second frame. A driven roller is rotatably installed inside each of the two groups of second frames. A limit plate is fixedly installed on the outside of each of the two groups of transmission rollers and the two groups of driven rollers. A sanding belt is driven and installed on the outside of each of the two groups of transmission rollers and the two groups of driven rollers. The two sanding belts are located between the two groups of transmission rollers and the two groups of driven rollers.

[0010] Furthermore, the multiple guide rollers are divided into multiple groups, and the multiple groups of guide rollers are located between the multiple mounting frames. The sidewalls of the multiple guide rollers and the sidewalls of the multiple sanding belts are in the same straight line. The rotation direction of the multiple guide rollers and the rotation direction of the multiple sanding belts are consistent with the transmission direction of the conveyor belt.

[0011] Furthermore, each of the mounting brackets has a slider that extends into the interior of the first frame fixedly mounted on its sidewall, and the inner sidewall of the first frame has a groove that matches the slider.

[0012] Furthermore, the limiting mechanism includes multiple connecting rods, all of which are fixedly connected to the outside of the conveyor belt. A horizontal plate is fixedly installed on the top of the multiple connecting rods. A second electric push rod is fixedly installed on the top of the horizontal plate. The output end of the second electric push rod passes through the horizontal plate and is fixedly installed on a third frame. Multiple limiting rollers are rotatably installed inside the third frame.

[0013] Furthermore, a plurality of limiting rods are fixedly installed on the top of the third frame, extending through and above the horizontal plate, and a limiting plate is fixedly installed on the top of each of the limiting rods.

[0014] Furthermore, the bottoms of the plurality of limiting rollers are aligned on the same straight line, and the rotation direction of the plurality of limiting rollers is consistent with the transmission direction of the conveyor belt.

[0015] Another technical problem solved by the present invention is to provide a grinding method for sheet metal production according to the above description, comprising the following specific steps:

[0016] S1. The sheet material is transferred from the previous station to the top of the conveyor belt. First, the adjusting mechanism is used to adjust the guiding mechanism to the designated position so that the guiding mechanism contacts both sides of the sheet material. S2. Then use the limiting mechanism to adjust to the designated position so that the limiting mechanism contacts the top of the board; S3. Then, use a conveyor belt to transport the sheet material, so that the guiding mechanism guides the two sides of the sheet material and the limiting mechanism limits the top of the sheet material. S4. Finally, the edge grinding mechanism is used to grind both sides of the board, and the conveyor belt transports the ground board to the next station.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects: This invention, by setting up a conveyor belt, an adjustment mechanism, a guiding mechanism, an edge grinding mechanism, and a limiting mechanism, first uses the conveyor belt to transport the board material, then uses the adjustment mechanism to adjust the positions of the guiding mechanism and the edge grinding mechanism, then uses the guiding mechanism in conjunction with the limiting mechanism to guide and limit the board material, and finally uses the edge grinding mechanism to grind both sides of the board material. The edge-ground board material is then transported to the next station. This not only improves the grinding accuracy and edge grinding effect, but also shortens the positioning time and improves the edge grinding efficiency. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-2 The edge grinding device for sheet production in this embodiment includes a conveyor belt 1, an adjustment mechanism 2, a guide mechanism 3, an edge grinding mechanism 4, and a limiting mechanism 5. The adjustment mechanism 2 is fixedly connected inside the conveyor belt 1, the guide mechanism 3 is fixedly connected to the free end of the adjustment mechanism 2, the edge grinding mechanism 4 is slidably connected inside the guide mechanism 3, and the limiting mechanism 5 is fixedly connected above the conveyor belt 1.

[0022] Specifically, the conveyor belt 1 is used to transport the board first, then the adjustment mechanism 2 is used to adjust the position of the guide mechanism 3 and the edge grinding mechanism 4, then the guide mechanism 3 is used in conjunction with the limiting mechanism 5 to guide and limit the board, and finally the edge grinding mechanism 4 is used to grind the edges of both sides of the board. The edge-ground board is then transported to the next station, which not only improves the grinding accuracy and edge grinding effect, but also shortens the positioning time and improves the edge grinding efficiency.

[0023] Please see Figure 3-4In this embodiment, the adjustment mechanism 2 includes a chamber 21, which is fixedly connected inside the conveyor belt 1. A dual-axis motor 22 is fixedly installed on the inner bottom wall of the chamber 21. Threaded rods 23 are fixedly installed on both output ends of the dual-axis motor 22. The threads of the two threaded rods 23 are opposite in direction and of equal length. The side of the two threaded rods 23 away from the output end of the dual-axis motor 22 is rotatably connected to the inner side wall of the chamber 21 through a first bearing. Threaded sleeves 24 are threadedly installed on the outside of the two threaded rods 23. Two adjusting rods 25 are fixedly installed on the outside of the two threaded sleeves 24. The four adjusting rods 25 are divided into two groups. Both groups of adjusting rods 25 pass through the chamber 21 and the conveyor belt 1 and extend to both sides of the conveyor belt 1. Adjusting holes matching the adjusting rods 25 are opened on the side wall of the chamber 21.

[0024] Specifically, by turning on the dual-axis motor 22, the dual-axis motor 22 drives the two threaded rods 23 to rotate, and the two threaded rods 23 drive the two threaded sleeves 24 and the two sets of adjusting rods 25 to move relative to each other or in opposite directions.

[0025] Please see Figure 3 In this embodiment, the guide mechanism 3 includes two first frames 31, which are fixedly connected to the top of two sets of adjusting rods 25 respectively. Guide plates 32 are fixedly installed on the side walls of the two first frames 31. The two guide plates 32 form a figure-eight shape. Sixteen guide rollers 33 are rotatably installed inside the two first frames 31 through the second bearing.

[0026] Specifically, during the process of conveying the sheet material by the conveyor belt 1, the guide plates 32 on both sides guide the sheet material towards the middle, so that the guide rollers 33 on both sides are in contact with the side wall of the sheet material. The sheet material drives the guide rollers 33 to rotate, which reduces the friction.

[0027] Please see Figure 5In this embodiment, the edge grinding mechanism 4 includes six mounting brackets 41, which are divided into two groups. The two groups of mounting brackets 41 are respectively fixedly connected to the bottom of two first frames 31. The side walls of the two groups of mounting brackets 41 are fixedly mounted with sliders extending into the interior of the first frame 31. The inner side wall of the first frame 31 is provided with a groove matching the slider. Sixteen guide rollers 33 are divided into two groups, which are located between three mounting brackets 41. The interior of each of the six mounting brackets 41 is fixedly mounted with a first electric push rod 42. The output ends of the six first electric push rods 42 all penetrate the first frame 31 and are fixedly mounted with a second frame 43. The top of each of the two first frames 31 is provided with a through hole matching the second frame 43. The top of each of the six second frames 43 is fixedly mounted with a motor 4. 4. The output ends of the six motors 44 all pass through the second frame 43 and are fixedly installed with transmission rollers 45. The bottom of the six transmission rollers 45 is rotatably connected to the inner bottom wall of the second frame 43 through the third bearing. The interior of the six second frames 43 is rotatably installed with driven rollers 46 through the fourth bearing. Two limit discs 47 are fixedly installed on the exterior of the six transmission rollers 45 and the exterior of the six driven rollers 46. Sanding belts 48 are driven and installed on the exterior of the six transmission rollers 45 and the exterior of the six driven rollers 46. The six sanding belts 48 are located between the six transmission rollers 45 and the six driven rollers 46. The side walls of the sixteen guide rollers 33 and the side walls of the three sanding belts 48 are in the same straight line. The rotation direction of the sixteen guide rollers 33 and the rotation direction of the six sanding belts 48 are consistent with the transmission direction of the transmission belt 1.

[0028] Specifically, by activating the first electric push rod 42, the first electric push rod 42 drives the chamber 43, motor 44, transmission roller 45, driven roller 46, limit plate 47 and sanding belt 48 to move up and down. By activating the motor 44, the motor 44 drives the transmission roller 45, driven roller 46, limit plate 47 and sanding belt 48 to rotate, so that the sanding belt 48 grinds the side wall of the board during the up and down movement.

[0029] Please see Figure 6 In this embodiment, the limiting mechanism 5 includes four connecting rods 51, all of which are fixedly connected to the side wall of the conveyor belt 1. The four connecting rods 51 are all L-shaped. A horizontal plate 52 is fixedly installed on the top of the four connecting rods 51. A second electric push rod 53 is fixedly installed on the top of the horizontal plate 52. The output end of the second electric push rod 53 passes through the horizontal plate 52 and is fixedly installed on a third frame 54. Four limiting rods that pass through and extend above the horizontal plate 52 are fixedly installed on the top of the third frame 54. A limiting plate is fixedly installed on the top of each of the four limiting rods. Seventeen limiting rollers 55 are rotatably installed inside the third frame 54 through a fifth bearing. The bottoms of the seventeen limiting rollers 55 are in the same straight line, and the rotation direction of the seventeen limiting rollers 55 is consistent with the transmission direction of the conveyor belt 1.

[0030] Specifically, by activating the second electric push rod 53, the second electric push rod 53 drives the third frame 54 and the limiting roller 55 to move downward, so that the bottom of the limiting roller 55 contacts the top of the plate.

[0031] Another technical problem solved by the present invention is to provide a grinding method for sheet metal production according to the above, comprising the following specific steps: S1. The sheet material is transferred from the previous station to the top of the conveyor belt 1. First, the adjusting mechanism 2 is used to adjust the guiding mechanism 3 to the specified position so that the guiding mechanism 3 contacts both sides of the sheet material. S2. Then use the limiting mechanism 5 to adjust to the designated position so that the limiting mechanism 5 contacts the top of the board; S3. Then use the conveyor belt 1 to drive the plate to be transported, so that the guide mechanism 3 guides the two sides of the plate and the limiting mechanism 5 limits the top of the plate. S4. Finally, the edge grinding mechanism 4 is used to grind both sides of the board, and the conveyor belt 1 transports the ground board to the next station.

[0032] The working principle of the above embodiments is as follows: First, the conveyor belt 1 is used to transport the sheet material. Then, the dual-axis motor 22 is turned on, which drives the two threaded rods 23 to rotate. The two threaded rods 23 drive the threaded sleeve 24 and the adjusting rod 25 to move relative to each other, thereby causing the first frame 31, guide plate 32, guide roller 33 and sanding belt 48 to move relative to each other to the designated position. The guide plates 32 on both sides guide the sheet material towards the middle, so that the guide rollers 33 on both sides contact the side wall of the sheet material. Then, the second electric push rod 53 is turned on, which drives the third frame 54 and the limiting roller 55 to move downward, so that the bottom of the limiting roller 55 contacts the top of the sheet material. The sheet material drives the guide roller 33 and the limiting roller 55 to rotate, reducing the friction. Finally, the first electric push rod 42 is turned on, which drives the chamber 43, motor 44, transmission roller 45, driven roller 46, limiting plate 47 and sanding belt 48 to move up and down. Simultaneously, motor 44 is turned on, which drives transmission roller 45, driven roller 46, limit plate 47 and sanding belt 48 to rotate. As the sanding belt 48 moves up and down, it grinds the side wall of the board. The ground board is then conveyed to the next station by conveyor belt 1. This not only improves the grinding accuracy and edge grinding effect, but also shortens the positioning time and improves the edge grinding efficiency.
