Description

Technical Field

[0001] This invention relates to an edge grinding device, and more particularly to a rapid edge grinding device for the production of environmentally friendly bamboo cutting boards, belonging to the field of bamboo cutting board production technology. Background Technology

[0002] Existing technology, such as the invention with application number 202322887883.X, discloses a rapid edge-grinding device for producing environmentally friendly bamboo cutting boards. To address the problem of low grinding efficiency on round cutting boards due to the inability to make the grinding wheel move circumferentially along the board, a cylinder drives a pressure plate to descend, limiting the bamboo cutting board's position. Two grinding motors drive two grinding wheels, allowing them to grind the bamboo cutting board simultaneously. A reduction motor drives one drive shaft to rotate at low speed, and two transmission gears drive the other drive shaft. The shaft rotates in reverse at low speed, and two incomplete gears drive the driven gear to rotate back and forth, which in turn enables the two grinding wheels to move in a circle along the bamboo cutting board. This facilitates all-round edge grinding of the round bamboo cutting board, improving the grinding speed and efficiency. The forward and reverse motors drive the forward and reverse threaded rods to rotate in the forward and reverse directions. The forward and reverse threaded rods can convert the rotational motion into the linear motion of the two slides through two threaded sleeves. The two slides can drive the two grinding motors to move, which can adjust the distance between the two grinding wheels and make it suitable for use with environmentally friendly bamboo cutting boards of different sizes.

[0003] The above applications still have shortcomings: During the edge grinding process of bamboo cutting boards, the lead screw needs to be manually adjusted to regulate the distance between the two sets of grinding wheels. It is impossible to adapt to the size of the bamboo cutting board during the edge grinding process, making the edge grinding process inconvenient. In addition, it is impossible to collect dust during the edge grinding process, which affects the processing environment.

[0004] To address these issues, a rapid edge-grinding device for the production of environmentally friendly bamboo cutting boards was designed. Summary of the Invention

[0005] The main objective of this invention is to provide an environmentally friendly rapid edge-grinding device for bamboo cutting board production. This device comprises a grinding mechanism consisting of a U-shaped plate, a lower conveyor roller, a conveyor motor, an upper conveyor roller, a tension roller, and sandpaper, symmetrically arranged on both sides of the mounting groove. A contact mechanism adjusts the contact area between the sandpaper and the bamboo cutting board according to its thickness, and a spacing adjustment mechanism adjusts the distance between the two grinding mechanisms according to the width of the bamboo cutting board. This allows the symmetrical edges of the bamboo cutting board to be automatically ground after passing through the box, eliminating the need for manual adjustment, thus improving practicality and grinding speed. The contact mechanism, consisting of a third slide, a guide plate, a second spring, a fourth slide, and a connecting rod, automatically controls the upward movement of the guide plate during the horizontal insertion of the bamboo cutting board. The connecting rod on the guide plate connects to the upper conveyor roller. The connection allows control of the upward movement of the upper conveyor roller, thereby controlling the length of the sandpaper between the upper and lower conveyor rollers. This ensures that the sides of the bamboo cutting board are completely covered by the sandpaper, guaranteeing that the sides are fully sanded after the bamboo cutting board passes through the box. A spacing adjustment mechanism consisting of a fifth slide, a third slider, a third spring, and a guide block allows the bamboo cutting board to contact the guide block after entering the box, pushing the guide block and sanding mechanism outwards. This automatically adjusts the spacing of the sanding mechanism according to the width of the bamboo cutting board, ensuring a good fit between the sandpaper and the board. A dust removal mechanism consisting of a collection trough, opening, filter, and negative pressure fan at the bottom of the box automatically absorbs and filters dust during the sanding process, preventing dust from floating and making it more environmentally friendly.

[0019] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] like Figures 1-7As shown, this embodiment provides a rapid edge grinding device for the production of environmentally friendly bamboo cutting boards, including a box body 1. The two ends of the box body 1 are open. The bottom of the box body 1 is provided with an installation groove 2 along the width direction. Both sides of the installation groove 2 are slidably provided with grinding mechanisms 3. The inside of the installation groove 2 is provided with a spacing adjustment mechanism 5 for adjusting the distance between the two grinding mechanisms 3 according to the thickness of the cutting board. The front end of the box body 1 is provided with a contact mechanism 4 for adjusting the grinding contact surface according to the thickness of the cutting board. The bottom of the box body 1 is provided with a dust removal mechanism 6. The end of the box body 1 away from the contact mechanism 4 is provided with a pressing mechanism 7.

[0021] Overall working principle: When grinding the edges of a chamfered rectangular bamboo cutting board, the bamboo cutting board is horizontally inserted from the front end of the box 1. During the insertion process, the contact mechanism 4 is squeezed, which adjusts the contact area between the grinding mechanism 3 and the side of the bamboo cutting board to ensure that the side of the bamboo cutting board is completely covered. As the bamboo cutting board continues to be inserted, the two sets of grinding mechanisms 3 are squeezed outward. The spacing of the grinding mechanisms 3 is adjusted according to the width of the cutting board to ensure the fit between the grinding mechanism 3 and the side of the cutting board. Then, when the bamboo cutting board moves horizontally through the inside of the box 1, the grinding mechanism 3 grinds the symmetrical sides of the cutting board and slides out from the rear end of the box 1 after grinding. In addition, during the grinding process, the dust collection mechanism 6 is used to collect and clean the generated dust.

[0022] In this embodiment, a guide roller 101 is uniformly rotatably mounted on the front end of the box 1 along the width direction, and the length of the guide roller 101 is greater than the spacing on the inner side of the box 1.

[0023] Local working principle: When the cutting board is pushed horizontally into the box 1, the use of guide roller 101 can reduce the moving resistance and facilitate insertion.

[0024] In this embodiment, the polishing mechanism 3 includes a U-shaped plate 301, a lower conveying roller 302, a conveying motor 303, an upper conveying roller 304, a tensioning roller 305, and sandpaper 306. The U-shaped plate 301 is symmetrically slidably disposed on both sides inside the mounting groove 2. The lower conveying roller 302 is rotatably mounted below the opposite ends of the U-shaped plate 301. The conveying motor 303 with its output shaft connected to the lower conveying roller 302 is mounted on the side of the U-shaped plate 301. The upper conveying roller 304 is rotatably mounted on the side of the U-shaped plate 301 and located vertically above the lower conveying roller 302. The upper conveying roller 304 can slide vertically on the U-shaped plate 301. The tensioning roller 305 is rotatably mounted on the end of the U-shaped plate 301 away from the lower conveying roller 302. The tensioning roller 305 can slide along the width direction of the U-shaped plate 301. Sandpaper 306 is disposed between the lower conveying roller 302, the upper conveying roller 304, and the tensioning roller 305.

[0025] Local working principle: When sanding the cutting board, the height of the sandpaper 306 in the vertical direction between the lower conveyor roller 302 and the upper conveyor roller 304 is greater than the thickness of the cutting board, so the side of the cutting board can be completely covered. Then, the conveyor motor 303 is started to drive the sandpaper 306 to rotate. The sandpaper 306 is sanded at the place where it is in contact with the side plate. After the cutting board passes through the box 1, the entire side is completely sanded.

[0026] In this embodiment, the U-shaped plate 301 has a first sliding groove 3041 vertically opened on both sides, and a first slider 3042 is slidably installed inside the first sliding groove 3041. Both ends of the upper conveying roller 304 are rotatably installed on the first slider 3042.

[0027] Local working principle: When the first slider 3042 moves vertically inside the first slide groove 3041, it can change the position of the upper conveying roller 304, thereby adjusting the height of the sandpaper 306 in the vertical direction between the lower conveying roller 302 and the upper conveying roller 304.

[0028] In this embodiment, a second slide groove 3051 is provided on each side of the U-shaped plate 301 along the length direction. A second slider 3052 is slidably installed inside each of the second slide grooves 3051. The ends of the tension rollers 305 are rotatably mounted on the second sliders 3052. A first spring 3053 is provided between the side of the second slider 3052 near the lower conveying roller 302 and the end of the second slide groove 3051.

[0029] Local working principle: When the position of the upper conveyor roller 304 is adjusted, since the circumference of the entire sandpaper 306 is fixed, the upward movement of the upper conveyor roller 304 will exert a certain tension on the tension roller 305. The tension roller 305 will move a certain distance toward the upper conveyor roller 304. Due to the presence of the first spring 3053, it can be ensured that the sandpaper 306 is in a taut state.

[0030] In this embodiment, the contact mechanism 4 includes a third slide groove 401, a guide plate 402, a second spring 403, a fourth slide groove 404, and a connecting rod 405. The third slide groove 401 is vertically opened on both sides of the front end of the housing 1. A guide plate 402 is vertically slidably installed between the two sets of third slide grooves 401. The end of the guide plate 402 is inserted into the interior of the third slide groove 401. A second spring 403 is provided between the upper part of the end of the guide plate 402 and the inner top of the third slide groove 401. The guide plate 402 is V-shaped, and the included angle between the two sides of the guide plate 402 is greater than 90 degrees. The bottom of the guide plate 402 is parallel to the horizontal plane. A fourth slide groove 404 is opened along the length direction on the side of the guide plate 402 near the interior of the housing 1. A connecting rod 405 is slidably installed at both ends of the fourth slide groove 404. The ends of the two sets of connecting rods 405 pass through the first slide groove 3041 and are fixedly connected to the first slider 3042.

[0031] Local working principle: When the cutting board is inserted horizontally, it will apply an upward pushing force to the guide plate 402, and the baffle 402 will move upward. During the movement of the baffle 402, the connecting rod 405 will be controlled to move upward. The connecting rod 405 will drive the upper conveying roller 304 to move automatically, and then adjust the height of the upper conveying roller 304 according to the thickness of the cutting board to ensure the contact area between the sanding paper 306 and the side of the cutting board.

[0032] In this embodiment, the spacing adjustment mechanism 5 includes a fifth slide groove 501, a third slider 502, a third spring 503, and a guide block 504. The fifth slide groove 501 is opened at the bottom of the mounting groove 2 along the width direction of the housing 1. The third slider 502 is slidably installed at both ends of the fifth slide groove 501. The third sliders 502 at both ends of the fifth slide groove 501 are respectively fixed to the bottom of the U-shaped plate 301. A third spring 503 is provided between the end of the third slider 502 and the fifth slide groove 501, as well as between the two sets of third sliders 502. A guide block 504 is fixed at one end of the U-shaped plate 301 near the guide plate 402. The two sets of guide blocks 504 are symmetrically arranged.

[0033] Local working principle: As the cutting board continues to be inserted, an outward pushing force is applied to the two sets of guide blocks 504, controlling the U-shaped plates 301 to move to both sides until the spacing between the U-shaped plates 301 is the same as the width of the cutting board. Since the front end of the cutting board has been chamfered, the front end is arc-shaped, and the width of the front end will be smaller than the width of the middle of the cutting board. In addition, in order to ensure the sanding effect, the sanding paper 306 at the end of the U-shaped plate 301 will protrude from the outside of the U-shaped plate 301, which will cause the spacing between the sanding paper 306 to be... The distance is less than the width of the middle of the cutting board. During the insertion of the cutting board, the width of the front part of the cutting board is also less than the width of the middle of the cutting board. The front part of the cutting board will first adhere to the sandpaper 306, so it can enter between the two sandpapers 306. After entering between the two sets of U-shaped plates 301 and adhering to the sandpaper 306, the side of the cutting board will exert a certain pressure on the sandpaper 306. The sandpaper 306 can better adhere to the side of the cutting board and grind the edge into an arc shape when sanding the edge.

[0034] In this embodiment, the pressing mechanism 7 includes a sixth slide groove 701, a fourth slider 702, a pressure roller 703, a fourth spring 704, and a fixing rod 705. The sixth slide groove 701 is vertically opened on both sides of the rear end of the housing 1. The fourth slider 702 is slidably arranged inside the sixth slide groove 701. The pressure roller 703 is rotatably installed between the two sets of fourth sliders 702. The fourth spring 704 is provided between the top of the fourth slider 702 and the inner top of the sixth slide groove 701. The fixing rod 705 is provided between the top of the two sets of fourth sliders 702 and the end of the guide plate 402.

[0035] Local working principle: When the cutting board moves to the rear after being sanded, the guide plate 402 is pushed upward during the process of the cutting board entering. Since there is a fixing rod 705 between the guide plate 402 and the fourth slider 702, the upward movement of the fourth slider 702 is controlled. Then, the height of the pressure roller 703 is automatically adjusted according to the thickness of the cutting board, so that the pressure roller 703 can fit against the top of the cutting board to limit it when the cutting board slides out, thus ensuring that the cutting board slides smoothly.

[0036] In this embodiment, the dust removal mechanism 6 includes a collection tank 601, an opening 602, a filter screen 603, and a negative pressure fan 604. The collection tank 601 is located at the bottom of the inner side of the housing 1. An opening 602 is provided between the top of the collection tank 601 and the bottom of the mounting groove 2. A filter screen 603 is provided inside the collection tank 601 and below the opening 602. A negative pressure fan 604 is installed on the outside of the housing 1, and the input end of the negative pressure fan 604 is connected to the inside of the collection tank 601.

[0037] Local working principle: When performing edge grinding, the negative pressure fan 604 is started to generate negative pressure inside the collection tank 601. Part of the powder produced by grinding falls directly into the collection tank 601 through the port 602, while the scattered powder enters the collection tank 601 along with the gas and is filtered through the filter screen 603. The powder is stored on the top of the filter screen 603.

[0038] In this embodiment, two sets of openings 602 are provided, and the openings 602 are located on both sides of the mounting groove 2 respectively.

[0039] Local working principle: With the setting of the dual port 602, some powder can fall directly into the collection tank 601 during the grinding process, ensuring the powder collection effect.
