Description

Technical Field

[0001] This utility model relates to the field of belt sander technology, and more specifically, to a vertical belt sander edge grinding device. Background Technology

[0002] A belt sander is a type of grinding equipment that uses a motor to drive a pulley to rotate, which in turn moves the sanding belt paper tensioned on the pulley. The sanding belt paper rubs against the workpiece to complete the grinding operation.

[0003] The existing workpiece has two roughly vertically oriented sides, and the belt sander needs to grind one of these sides. Currently, when using a belt sander, the workpiece needs to be manually fixed on a specific carrier with the side to be sanded facing the sander. The sanding is achieved by rotating the sanding belt. After sanding, the workpiece must be manually removed, which is cumbersome, time-consuming, and labor-intensive, resulting in low overall sanding efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing devices are time-consuming and labor-intensive to operate, and have low grinding efficiency. In order to overcome the above-mentioned defects of the prior art, this utility model provides a simpler and more reasonable structure, which realizes the conveying through the conveyor belt mechanism, saving time and labor, and uses the clamping component to press the workpiece against the sanding belt edge grinding component to achieve edge grinding, eliminating the need for manual clamping of the workpiece, and further improving the edge grinding quality and edge grinding efficiency.

[0005] To achieve the purpose of this utility model, the following technical solution is adopted:

[0006] A vertical belt sander edge grinding device includes a frame, a conveyor belt mechanism, and at least one edge grinding mechanism. The conveyor belt mechanism is used for horizontal conveying of workpieces. Each edge grinding mechanism includes a belt sander edge grinding assembly and a pressing assembly. The belt sander edge grinding assembly and the pressing assembly are located on opposite sides of the conveyor belt. The belt sander edge grinding assembly includes an edge grinding positioning unit, an edge grinding drive unit, and sanding belt paper. The edge grinding positioning unit is mounted on the frame, and the edge grinding drive unit is mounted on the edge grinding positioning unit. The edge grinding positioning unit is used to drive the edge grinding drive unit to move closer to or away from the conveyor belt. The sanding belt paper is tightly connected to the edge grinding drive unit, and the edge grinding drive unit is used to drive the sanding belt paper to rotate cyclically to grind the workpiece. The pressing assembly is used to horizontally press the workpiece on the conveyor belt against the sanding belt paper, and the rotating sanding belt paper grinds one side of the workpiece. This device simplifies and optimizes the structure by placing the belt abrasive edge grinding assembly and the clamping assembly on both sides of the conveyor belt mechanism, reducing the space occupied and lowering costs. Meanwhile, the clamping assembly presses the workpiece against and clamps it onto the belt abrasive edge grinding assembly, facilitating precise grinding of one side of the workpiece and improving the edge grinding quality. Furthermore, the device is equipped with a conveyor belt drive assembly to achieve automatic conveying, eliminating the need for manual clamping and ensuring grinding accuracy while significantly improving edge grinding efficiency.

[0007] Preferably, the edge grinding drive unit includes an edge grinding bracket, an edge grinding motor, a drive roller, and at least one driven roller. The edge grinding bracket is fixed to the edge grinding positioning unit and located on one side of the conveyor belt. The edge grinding motor is mounted on the edge grinding bracket, the drive roller is connected to the drive unit of the edge grinding motor, and the driven roller is rotatably connected to the edge grinding bracket, with the driven roller arranged parallel to the drive roller. The sanding belt paper is tightly connected to the drive roller and the driven roller. This structure, through the edge grinding motor driving the drive roller to rotate, and with the cooperation of the driven roller, achieves the cyclic rotation of the sanding belt paper, thereby enabling the surface of the sanding belt paper to grind the workpiece.

[0008] Preferably, there are two driven rollers, each rotatably connected to the grinding bracket near the conveyor belt. The two driven rollers are vertically aligned and cooperate with the driving roller to distribute the tensioned sanding tape in a right-angled triangular shape, with the vertical right-angled side of the triangular sanding tape serving as the grinding surface. This structure, with the driven rollers aligned and located on the same side of the driving roller, facilitates the formation of a stable triangular shape and a vertical grinding surface, thus enabling better grinding of the workpiece.

[0009] Preferably, a grinding support plate is also provided on the grinding bracket between the two driven rollers, and the supporting surface of the grinding support plate is flush with the grinding surface of the sanding belt paper. The grinding support plate facilitates the support of the sanding belt paper during grinding, thereby preventing deformation of the sanding belt paper during grinding and ensuring the grinding effect and grinding accuracy of the sanding belt paper.

[0010] Preferably, the grinding bracket includes a horizontal support plate and a vertical support plate, with a triangular reinforcing plate positioned between them. The vertical support plate has a transverse through-hole. The grinding motor is horizontally mounted on the horizontal support plate via a motor bracket, and its drive unit passes through the through-hole and connects to the driving roller. The driven roller is rotatably connected to the vertical support plate. This structure, with its horizontal and vertical support plates, facilitates the installation of the grinding motor and the driven roller, and allows for a height difference between the driven and driving rollers, facilitating the formation of a vertical grinding surface and enabling effective grinding of the workpiece.

[0011] Preferably, the edge grinding positioning unit includes a positioning base, a positioning drive motor, a positioning lead screw, and a positioning slide. The positioning base is mounted on the frame and located on one side of the conveyor belt. The positioning drive motor is mounted on the positioning base.

A positioning slider is rotatably connected to the positioning lead screw. The positioning slide is fixedly connected to the positioning slider, and a positioning slide rail is provided between the positioning slide and the positioning base to enable horizontal movement of the positioning slide. The edge grinding drive unit is mounted on the positioning slide. By driving the positioning lead screw to rotate through the positioning drive motor, and cooperating with the positioning slider, the positioning slide can move horizontally, thereby facilitating the positioning slide to move the edge grinding drive unit closer to or away from the conveyor belt. This ensures precise positioning during grinding and guarantees the edge grinding effect on the workpiece.

[0012] Preferably, the clamping assembly includes a clamping bracket, a clamping electric cylinder, a clamping positioning platform, a pressure plate, and a clamping limiting part. The clamping bracket is fixed to the frame and located on the other side of the conveyor belt. The clamping electric cylinder is horizontally mounted on the clamping bracket. The clamping positioning platform is horizontally fixedly connected to the moving part of the clamping electric cylinder. The pressure plate is horizontally slidably connected to the clamping positioning platform via a clamping horizontal slide rail. The clamping limiting part is located on the side of the clamping positioning platform away from the conveyor belt and is used to block the pressure plate during edge grinding. Several spaced and flush clamping guide wheels are arranged on the side of the pressure plate near the conveyor belt, and each clamping guide wheel is vertically distributed. This structure, through the clamping electric cylinder driving the pressure plate on the clamping positioning platform to press against the workpiece, can press the workpiece onto the sanding paper. Furthermore, the clamping guide wheels enable grinding while ensuring the workpiece continues to be conveyed to the discharge end, greatly improving grinding efficiency.

[0013] Preferably, a gap baffle is also provided on the pressure plate between two adjacent pressure guide rollers; the gap baffle is used to prevent the workpiece from getting stuck in the gap between the two pressure guide rollers. The gap baffle can prevent one end of the workpiece from getting stuck in the gap between two adjacent pressure guide rollers during pressing and grinding, ensuring that the workpiece is transported and ground horizontally and stably, thus ensuring the grinding effect.

[0014] Preferably, all gap baffles are on the same plane and located inside the contact end of the pressure guide roller. This structure ensures the flatness between the gap baffles and also ensures contact between the workpiece and the pressure guide roller, thus ensuring stability during conveying and precision in grinding.

[0015] Preferably, the conveyor belt mechanism includes a conveyor belt and a conveyor belt drive assembly; the conveyor belt drive assembly is horizontally mounted on the frame, the conveyor belt is tensioned and connected to the conveyor belt drive assembly, and the conveyor belt drive assembly is used to drive the conveyor belt to rotate cyclically to achieve horizontal conveying of the workpiece; the conveyor belt drive assembly includes a conveyor belt drive bracket, a conveyor belt drive motor, a conveyor belt drive roller, and a conveyor belt driven roller; the conveyor belt drive bracket is vertically mounted on the frame; the conveyor belt drive motor is horizontally mounted on the conveyor belt drive bracket, the conveyor belt drive roller is connected to the output shaft of the conveyor belt drive motor, the conveyor belt driven roller is rotatably connected to the conveyor belt drive bracket, the conveyor belt is tensioned and connected to the conveyor belt drive roller and the conveyor belt driven roller, and conveyor belt baffles are provided on both sides of the conveyor belt on the conveyor belt drive bracket to prevent workpieces from falling off. The above structure uses a conveyor belt drive motor to move the active roller of the conveyor belt, and with the cooperation of the driven roller of the conveyor belt, it realizes the cyclic conveying of the conveyor belt. No manual clamping is required, which greatly improves the conveying efficiency and grinding efficiency. At the same time, the limit of the conveyor belt baffle can prevent the workpiece from deviating from the conveyor belt or falling off during the conveying process.

[0016] In summary, the advantages of this utility model are that by placing the sanding belt edge grinding component and the clamping component on both sides of the conveyor belt mechanism, the structure becomes simpler and more reasonable, reducing the space occupied by the structure and lowering the cost. At the same time, by using the clamping component to press and hold the workpiece against the sanding belt edge grinding component, it is possible to accurately grind one side of the workpiece, improving the edge grinding quality. Furthermore, by cooperating with the conveyor belt drive component for automatic conveying, no manual clamping is required, ensuring grinding accuracy while greatly improving edge grinding efficiency.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5 As shown, a vertical belt sander edge grinding device includes a frame 1, a conveyor belt mechanism 2, and at least one edge grinding mechanism, such as... Figure 1 As shown, this embodiment includes two edge-grinding mechanisms arranged sequentially along the workpiece conveying direction. The two edge-grinding mechanisms are in opposite directions and are used to grind the opposite sides of the workpiece. The conveyor belt mechanism 2 is arranged along the front-to-back direction and includes a conveyor belt 21 and a conveyor belt drive assembly 22. The conveyor belt drive assembly 22 is horizontally mounted on the frame 1. The conveyor belt 21 is tensioned and connected to the conveyor belt drive assembly 22, and the conveyor belt drive assembly 22 drives the conveyor belt 21 to rotate cyclically, thus achieving horizontal conveying of the workpiece. Each edge-grinding mechanism includes a sanding belt edge-grinding assembly 3 and a pressing assembly 4. The sanding belt edge-grinding assembly 3 and the pressing assembly 4 are located on the left and right sides of the conveyor belt 21, respectively. The positions of the sanding belt edge-grinding assembly 3 and the pressing assembly 4 on the two edge-grinding mechanisms are opposite, thereby facilitating the grinding of the opposite sides of the workpiece. The belt sanding assembly 3 includes a sanding positioning unit, a sanding drive unit, and sanding belt paper 30. The sanding positioning unit is mounted on the frame 1, and the sanding drive unit is mounted on the sanding positioning unit. The sanding positioning unit drives the sanding drive unit to move closer to or away from the conveyor belt 21. The sanding belt paper 30 is tensioned and connected to the sanding drive unit, and the sanding drive unit drives the sanding belt paper 30 to rotate cyclically to achieve sanding of the workpiece. The clamping assembly 4 is used to horizontally press the workpiece on the conveyor belt 21 against the sanding belt paper 30, and the rotating sanding belt paper 30 achieves edge sanding on one side of the workpiece. By placing the belt sanding assembly 3 and the clamping assembly 4 on both sides of the conveyor belt mechanism 2, the device has a simpler and more reasonable structure, reduces the space occupied by the structure, and lowers the cost. At the same time, by pressing the workpiece against and clamping it against the belt sanding assembly 3 through the clamping assembly 4, it is convenient to accurately sand one side of the workpiece, improve the edge sanding quality, and achieve automatic conveying by cooperating with the conveyor belt drive assembly 2, eliminating the need for manual clamping, ensuring sanding accuracy while greatly improving edge sanding efficiency.

[0029] like Figures 1 to 3As shown, the conveyor belt drive assembly 22 includes a conveyor belt drive bracket 221, a conveyor belt drive motor 222, a conveyor belt drive roller 223, and a conveyor belt driven roller 224. The conveyor belt drive bracket 221 is vertically mounted on the frame 1 and is distributed in a front-to-back direction. The conveyor belt drive motor 222 is horizontally mounted on the conveyor belt drive bracket 221. The output shaft of the conveyor belt drive motor 222 passes through the conveyor belt drive bracket 221 and is connected to the conveyor belt drive roller 223. The conveyor belt driven roller 224 is rotatably connected to the conveyor belt drive bracket 221 and is horizontally mounted on the same side as the conveyor belt drive roller 223. The conveyor belt 21 is tensioned and connected to the conveyor belt drive roller 223 and the conveyor belt driven roller 224. Conveyor belt baffles 225 are provided on both sides of the feed end and both sides of the discharge end of the conveyor belt 21 to prevent workpieces from falling. This component drives the conveyor belt drive motor 222 to move the conveyor belt drive roller 223, and with the cooperation of the conveyor belt driven roller 224, realizes the cyclic conveying of the conveyor belt 21. No manual clamping is required, which greatly improves the conveying efficiency and grinding efficiency. At the same time, the conveyor belt baffle 225 limits the workpiece to prevent it from deviating from the conveyor belt 21 or falling off during conveying.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the edge grinding positioning unit includes a positioning base 36, a positioning drive motor 37, a positioning lead screw 38, and a positioning slide 39. The positioning base 36 is mounted on the frame 1 and located on one side of the conveyor belt 21. The positioning drive motor 37 is mounted on the positioning base 36. One end of the positioning lead screw 38 is connected to the output shaft of the positioning drive motor 37. The other end of the positioning lead screw 38 is rotatably connected to the positioning base 36. A positioning slider is rotatably connected to the positioning lead screw 38, allowing the rotatably connected positioning slider to move horizontally. The positioning slide 39 is fixedly connected to the top of the positioning slider, and a positioning slide rail 391 is also provided between the positioning slide 39 and the positioning base 36, enabling the positioning slide 39 to move horizontally left and right. The edge grinding drive unit is mounted on the positioning slide 39. The positioning drive motor 37 drives the positioning screw 38 to rotate, which, together with the positioning slider, enables the positioning slide 39 to move horizontally left and right. This facilitates the positioning slide 39 to drive the edge grinding drive unit closer to or away from the conveyor belt 21, thereby enabling precise positioning of the sanding paper 30 during grinding and ensuring the edge grinding effect on the workpiece.

[0031] like Figure 4As shown, the edge grinding drive unit includes an edge grinding bracket 31, an edge grinding motor 32, a drive roller 33, and at least one driven roller 34. The edge grinding bracket 31 is fixed on the edge grinding positioning unit and located on one side of the conveyor belt 21. The edge grinding motor 32 is horizontally mounted on the edge grinding bracket 31 in a left-right direction via a motor bracket 321. The drive roller 33 is connected to the drive unit of the edge grinding motor 32, and the driven roller 34 is rotatably connected to the edge grinding bracket 31. The sanding tape 30 is tensioned and connected to the drive roller 33 and the driven roller 34. The edge grinding motor 32 drives the drive roller 33 to rotate, and with the cooperation of the driven roller 34, the sanding tape 30 is circulated, thereby enabling the surface of the sanding tape 30 to grind the workpiece and making the overall structure simpler.

[0032] like Figure 4 As shown, in this embodiment, the edge grinding bracket 31 includes a horizontal support plate 311 and a vertical support plate 312. A triangular reinforcing plate 313 is provided between the horizontal support plate 311 and the vertical support plate 312 to further enhance the connection strength and structural stability of the bracket. The vertical support plate 312 has a through-hole 314 extending in the left-right direction. The edge grinding motor 32 is horizontally mounted on the horizontal support plate 311, and the drive unit of the edge grinding motor 32 passes through the through-hole 314 and connects to the drive roller 33. The driven roller 34 is rotatably connected to the vertical support plate 312, and the driven roller 34 is parallel to and on the same side as the drive roller 33. The horizontal support plate 311 and the vertical support plate 312 on the edge grinding bracket 31 facilitate the installation of the edge grinding motor 32 and the driven roller 34, and allow the driven roller 34 and the drive roller 33 to form a height difference, facilitating the formation of a vertical grinding surface and enabling effective grinding of the workpiece.

[0033] like Figure 4 As shown, in this embodiment, there are two driven rollers 34. The two driven rollers 34 are rotatably connected to the edge grinding bracket 31 on the side near the conveyor belt 21. The two driven rollers 34 are vertically aligned and cooperate with the driving roller 33 to distribute the tensioned sanding tape 30 in a right-angled triangular shape. The alignment of the driven rollers 34 and their location on the same side of the driving roller 33 facilitates the formation of a stable triangle, ensuring stable rotation of the sanding tape 30 for stable grinding and further guaranteeing the grinding effect on the workpiece. Simultaneously, the vertical right-angled side 301 of the right-angled triangular sanding tape 30 serves as the grinding surface. This vertical grinding surface facilitates better grinding of the workpiece's sides, ensuring a smooth and even edge. A grinding support plate 35 is also provided on the edge grinding bracket 31 between the two driven rollers 34, and the support surface of the grinding support plate 35 is flush with the grinding surface of the sanding tape 30. The grinding support plate 35 facilitates the support of the sanding belt 30 during grinding, thereby preventing the sanding belt 30 from deforming during grinding, thus ensuring the support of the sanding belt 30, as well as the grinding effect and grinding accuracy of the workpiece.

[0034] like Figure 5 As shown, the clamping assembly 4 and the sanding belt edge grinding assembly 3 are arranged opposite each other and aligned left and right. The clamping assembly 4 includes a clamping bracket 41, a clamping electric cylinder 42, a clamping positioning platform 43, a pressure plate 44, and a clamping limiting part 45. The clamping bracket 41 is fixed on the frame 1 and located on the other side of the conveyor belt 21. The clamping electric cylinder 42 is arranged horizontally on the clamping bracket 41. The clamping electric cylinder 42 can also be replaced by a hydraulic cylinder, a pneumatic cylinder, or other driving components that achieve horizontal movement. The clamping and positioning platform 43 is horizontally fixedly connected to the moving part 421 of the clamping electric cylinder 42. The pressure plate 44 is horizontally slidably connected to the clamping and positioning platform 43 via the clamping horizontal slide rail 46. The sliding connection of the pressure plate 44 ensures that the workpiece does not directly and rigidly contact the sanding tape 30 during the clamping process, and provides a certain buffer sliding effect for the workpiece, preventing the workpiece from directly contacting the rapidly rotating sanding tape 30. This ensures that the workpiece is slowly pressed against the sanding tape 30 for grinding, preventing damage to the workpiece, ensuring grinding accuracy, and making the overall structure simpler and more reasonable. The clamping and limiting part 45 is set on the side of the clamping and positioning platform 43 away from the conveyor belt 21, and the clamping and limiting part 45 is used to block the pressure plate 44 during edge grinding. In this embodiment, the clamping and limiting part 45 is a pressure line limiting block, and a left and right clamping and limiting post is provided on the pressure line limiting block to achieve the limiting. Several equally spaced and flush clamping guide rollers 47 are arranged on the side of the pressure plate 44 near the conveyor belt 21, and each clamping guide roller 47 is vertically distributed. The clamping electric cylinder 42 drives the pressure plate 44 on the clamping positioning platform 43 to press against the workpiece and press the workpiece against the sanding paper 30. The clamping guide rollers 47 can achieve grinding while ensuring that the workpiece continues to be conveyed to the discharge end, which greatly improves the grinding efficiency. It can also be conveyed to a designated position, stopped for grinding, and then conveyed again.

[0035] like Figure 5 As shown, a gap baffle 48 is also provided on the pressure plate 44 between two adjacent pressure guide rollers 47; the gap baffle 48 is used to prevent the workpiece from getting stuck in the gap between the two pressure guide rollers 47. The gap baffle 48 prevents one end of the workpiece from getting stuck in the gap between the two adjacent pressure guide rollers 47 during pressure grinding, ensuring that the workpiece is conveyed and ground horizontally and smoothly, thus ensuring the grinding effect. All gap baffles 48 are on the same plane, and the gap baffles 48 are located inside the contact end of the pressure guide rollers 47. The above structure ensures the flatness between the gap baffles 48, and also ensures that the workpiece is in contact with the pressure guide rollers 47, ensuring the stability of the conveying process and the accuracy of the grinding.

[0036] During operation, the workpiece is manually or robotically transported onto the conveyor belt 21. The conveyor belt drive motor 222 on the conveyor belt mechanism 2 drives the active roller 223 to rotate, and with the cooperation of the driven roller 224, the conveyor belt 21 rotates cyclically, thus transporting the workpiece on the conveyor belt 21 towards the discharge end. The workpiece is then transported between the sanding belt edge-grinding assembly 3 and the pressing assembly 4 of the first edge-grinding mechanism. The positioning drive motor 37 in the edge-grinding positioning unit on the sanding belt edge-grinding assembly 3 drives the positioning screw 38 to rotate. This, combined with the positioning slider, drives the edge-grinding drive unit on the positioning slide 39 to gradually approach the conveyor belt 21 until it reaches the designated position. After edge-grinding and positioning, the edge-grinding motor 32 on the edge-grinding drive unit drives the active roller 33 to rotate, and with the cooperation of the driven roller 34, the sanding belt paper 30 rotates cyclically, waiting for the workpiece to be pressed before proceeding. The edge grinding process is as follows: When the belt grinding assembly 3 is activated, the clamping assembly 4 drives the clamping positioning platform 43 to press the pressure plate 44 against the workpiece through the clamping electric cylinder 42. The clamping guide roller 47 on the pressure plate 44 presses the workpiece against the sanding belt paper 30 of the belt grinding assembly 3. When the workpiece contacts the sanding belt paper 30, the pressure plate 44 is pushed forward, so that the pressure plate 44 slides on the clamping positioning platform 43 until it stops against the clamping limit part 45, thereby ensuring that the workpiece is pressed between the clamping guide roller 47 and the sanding belt paper 30. The workpiece is ground on one side by rotating the sanding belt paper 30. After the edge grinding is completed, the belt grinding assembly 3 and the clamping assembly 4 move away from each other to the sides. The conveyor belt 21 continues to transport the workpiece between the belt grinding assembly 3 and the clamping assembly 4 of the second edge grinding mechanism. The workpiece is ground on the other side by the same action, and finally the edge grinding of the two opposite sides of the workpiece is achieved.

[0037] The advantages of this invention are that by setting the sanding belt edge grinding component 3 and the clamping component 4 on both sides of the conveyor belt mechanism 2, the structure becomes simpler and more reasonable, reducing the space occupied by the structure and lowering the cost. At the same time, by pressing the workpiece against and clamping it onto the sanding belt edge grinding component 3 through the clamping component 4, it is possible to accurately grind one side of the workpiece and improve the edge grinding quality. Furthermore, by cooperating with the conveyor belt drive component 2, automatic conveying is achieved without manual clamping, ensuring grinding accuracy while greatly improving edge grinding efficiency.
