DETAILED DESCRIPTION

[0020] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] The present invention provides a technical solution: referring to Figure 1 - Fig.15 The present invention discloses a bamboo chip burr grinding device for bamboo board processing, comprising a storage box 1 fixedly mounted on two supporting legs, a grinding assembly 2 is provided on the top side of the storage box 1 and inside the storage box 1, the grinding assembly 2 comprises a cover 21, the cover 21 is arranged on the top side of the storage box 1, a grinding plate 22 is provided in the storage box 1, and the outer peripheral wall of the grinding plate 22 contacts the inner wall of the storage box 1 and the bottom side of the cover 21, a plurality of grinding holes 23 are equidistantly provided on the grinding plate 22, an annular groove 24 is provided on the outer peripheral wall of the grinding plate 22, a sealing ring 25 is provided in the annular groove 24, and the sealing ring 25 contacts the inner wall of the storage box 1, the bottom side of the grinding plate 22 and the inner wall of the annular groove 24, an air bag 26 in a ring shape is fixedly installed and penetrated in the grinding hole 23, four grinding plate bodies 27 are relatively fixedly installed on the inner ring wall of the air bag 26, and two adjacent grinding plate bodies 27 are clearance-matched, and the grinding plate body 27 is sponge sandpaper; An adjusting mechanism 3 is provided inside the plate wall of the grinding plate 22, a driving mechanism 4 is provided at both the front and rear ends of the grinding plate 22, a debris collecting assembly 5 is provided at the bottom end of the storage box 1, and a plurality of clamping assemblies 6 are provided at both ends of the storage box 1.

[0022] In this embodiment, when the improved bamboo board processing bamboo chip burr grinding device is used, the operator first holds the handle of the cover 21 to lift the front end of the cover 21 to release the blocking state of the top opening of the storage box 1, and then the operator sequentially inserts the bamboo chips into the storage box 1 from the top opening of the storage box 1, and makes the bamboo chips pass through the plurality of grinding holes 23 in sequence, and then the bamboo chips are clamped and positioned by the clamping assembly 6, and the plurality of bamboo chips are clamped and fixed at the corresponding positions in the storage box, and the feeding operation of the bamboo chips is completed; After the loading operation of the bamboo chips is completed, the operator rotates the cover 21 in the opposite direction so that the bottom side of the cover 21 is again fitted with the top of the storage box 1 to reclose the top opening of the storage box 1, and then the driving mechanism 4 is started, and the driving mechanism 4 cooperates with the adjusting mechanism 3 to pull the grinding plate 22 located in the storage box 1 to slide to the right. First, the adjusting mechanism 3 injects a specific amount of gas into the airbag 26. As the airbag 26 expands, the airbag 26 pushes the grinding plate body 27 toward the bamboo chip. Due to the friction deformation between the grinding plate body 27 and the bamboo chip and the mutual friction deformation of the grinding plate body 27, several grinding plates in the same grinding hole 23 cooperate with each other to form corresponding square ring-shaped grinding surfaces according to the processed bamboo chip, and the grinding surface is tightly fitted with the outer wall of the bamboo chip, so that when the grinding plate 22 continues to move slowly to the right, the grinding operation of the bamboo chip burrs is completed because the grinding surface slides in contact with the outer wall of the bamboo chip; After the grinding plate 22 moves to the rightmost end of the bamboo piece, the driving mechanism 4 cooperates with the adjusting mechanism 3 to drive the grinding plate 22 to slide rapidly to the left in the storage box 1, and firstly, the gas injected into the airbag 26 is extracted, and the contracted airbag 26 works the grinding plate body 27 in the direction away from the bamboo piece, so that a certain size of gap is formed between the bamboo piece and the grinding plate body 27 and between the bamboo piece and the inner wall of the airbag 26. In addition, during the rapid movement of the grinding plate 22 to the left, the gas at the left end of the storage box 1 can be compressed, so that a pressure difference is formed at both ends of the gap, and finally part of the gas at the left end of the storage box 1 passes through the gap and flows into the storage box 1. The right end of the bamboo sheet is formed at each part of the bamboo sheet outer wall, so that the airflow of a certain intensity is formed in turn at each part of the bamboo sheet outer wall, and the powder waste attached to the bamboo sheet is blown down. The gas flowing out of the gap flows to the larger space at the right end of the storage box 1, so that the flow rate of the outflowing airflow immediately decreases until the flow rate of the airflow returns to zero. After blowing the powder waste on the bamboo sheet down, the airflow will not continue to blow up a large amount of powder waste, and due to the effect of the powder waste's own gravity, the powder waste directly falls onto the inner bottom wall of the storage box 1. Finally, the burrs on the bamboo sheet outer wall are removed by the reciprocating movement of the grinding plate 22, and the polishing operation of the bamboo sheet outer wall is completed simultaneously. During the reciprocating movement of the grinding plate 22, it slides along the inner wall of the storage box 1, thereby pushing the powder waste attached to the inner wall of the storage box 1, and cooperates with the debris collection component 5 to clear most of the powder waste from the storage box 1, and collects the powder waste to a specific location for storage, and the device has a high degree of automation.

[0023] In a further preferred embodiment of the present invention, Figure 1 As shown, the bottom side of the cover 21 contacts the top side of the storage box 1, the rear end of the cover 21 is hinged to the storage box 1, the front end of the cover 21 is fixedly connected to the storage box 1 through a buckle, and the cover 21 is made of a transparent plate; In this embodiment, when performing the grinding operation on the burrs of the bamboo pieces, the operator can observe the grinding status of the burrs of the bamboo pieces in the storage box 1 through the cover 21 to avoid over-grinding of the bamboo pieces or a very small amount of burrs remaining on the outer wall of the bamboo pieces, so as to ensure the processing effect of the bamboo pieces.

[0024] In a further preferred embodiment of the present invention, Figure 2 , Fig.10 , Fig.11 and Fig.12 As shown, the regulating mechanism 3 includes a piston plate 32 arranged in an annular shape, a plurality of air storage grooves 31 are opened in the plate wall of the grinding plate 22, and the air storage grooves 31 are sleeved at the middle position of the outer peripheral side of the plurality of grinding holes 23, the piston plate 32 is arranged in the air storage groove 31, and the inner and outer ring walls of the piston plate 32 are in contact with the inner wall of the air storage groove 31, the interior of the airbag 26 is connected with the interior of the air storage groove 31 through a plurality of connecting holes 33, two pull rods 34 are relatively slidably installed at the middle position on the right side of the grinding plate 22, and the left end of each pull rod 34 is inserted into the air storage groove 31 and fixedly connected to the piston plate 32, a sealing ring 35 is fixedly installed at the position corresponding to the pull rod 34 in the plate wall of the grinding plate 22, and the inner ring wall of the sealing ring 35 is in contact with the outer peripheral wall of the corresponding pull rod 34, a plurality of air inlet holes 37 are opened at the position corresponding to the air storage groove 31 on the left side of the grinding plate 22, and the interior of each air inlet hole 37 is connected with the interior of the air storage groove 31; In this embodiment, when the above-mentioned driving mechanism 4 pulls the grinding plate 22 to the right, it will first pull the piston plate 32 to the right through the pull rod 34. At this time, due to the friction between the grinding plate 22 and the inner wall of the storage box 1 and the cover 21, the pull rod 34 will first drive the piston plate 32 located in the air storage tank 31 to slide to the right and push the gas in the air storage tank 31. At this time, part of the gas in the air storage tank 31 flows into the air bag 26 through the connecting hole 33, so that the air pressure in the air bag 26 and the air storage tank 31 increases. At this time, due to the push of the gas in the air bag 26, the air bag 26 expands, and the expanded air bag 26 pushes the grinding plate body 27 in the direction of the bamboo piece. Due to the contact deformation between the grinding plate body 27 and the bamboo piece and the mutual contact deformation of the grinding plate body 27, several grinding plates in the same grinding hole 23 cooperate with each other to form corresponding square ring-shaped annular grinding surfaces according to the processed bamboo piece and fit with the outer wall of the bamboo piece. The operator does not need to perform other operations, and there is no need to set an additional driving source, thereby reducing the manufacturing cost of the device.

[0025] In a further preferred embodiment of the present invention, Fig.11 and Fig.13As shown, a plurality of first springs 36 are relatively arranged between the piston plate 32 and the inner wall of the air storage tank 31, and the two ends of each first spring 36 are respectively fixedly connected to the piston plate 32 and the inner wall of the air storage tank 31, and the plurality of first springs 36 are divided into two groups and relatively arranged on the upper and lower sides of the plurality of connecting holes 33, and the spacing between two adjacent first springs 36 in each group is equal; In this embodiment, when the above-mentioned driving mechanism 4 pushes the grinding plate 22 to the left, the friction between the grinding plate 22 and the inner wall of the storage box 1 and the friction between the grinding plate 22 and the bottom side of the cover 21, as well as the push of the piston plate 32 by the first spring 36, first the pull rod 34 pushes the piston plate 32 to slide to the left in the air storage tank 31, and as the piston plate 32 is reset, the space between the right side of the piston plate 32 and the inner wall of the air storage tank 31 expands, and since there is no inflow of external gas, a negative pressure cavity of corresponding strength is formed between the right side of the piston plate 32 and the inner wall of the air storage tank 31 and in the airbag 26, and the contracted airbag 26 pulls the grinding plate body 27 away from the bamboo piece, thereby forming a certain size of gap between the bamboo piece and the grinding plate body 27 and between the bamboo piece and the inner wall of the airbag 26, without the operator having to perform other operations or setting an additional driving source, thereby reducing the manufacturing cost of the device.

[0026] In a further preferred embodiment of the present invention, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the driving mechanism 4 includes two drivers 44, a scraper 41 is fixedly installed on the right end of the pull rod 34 by bolts, a guide groove 42 is opened at the position corresponding to the scraper 41 on the inner wall of the storage box 1, and the end of the scraper 41 close to the corresponding guide groove 42 is inserted into the corresponding guide groove 42, a threaded rod 43 is installed through the thread on the scraper 41, and both ends of the threaded rod 43 are rotatably connected to the box wall of the storage box 1, and the driver 44 is fixedly installed at the position corresponding to the threaded rod 43 on the right side of the storage box 1, and the driving end of the driver 44 is fixedly connected to the right end of the corresponding threaded rod 43; In this embodiment, when the driving mechanism 4 drives the grinding plate 22 to slide left and right in the storage box 1, the driver 44 is first started to drive the threaded rod 43 to rotate forward or reversely. Due to the mutual interference with the inner wall of the guide groove 42, the scraper 41 fits the inner wall of the guide groove 42 and moves back and forth in the guide groove 42 along a linear trajectory.

[0027] In a further preferred embodiment of the present invention, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the inner bottom wall of the guide groove 42 is arranged in an inclined shape, the cross-sectional shape of the opposite ends of the two scrapers 41 is arranged in a trapezoidal shape, and the part of each scraper 41 located in the corresponding guide groove 42 is connected to the inner wall of the corresponding guide groove 42; In this embodiment, while the scraper 41 is sliding in the guide groove 42, the powder waste attached to the inner wall of the guide groove 42 can be scraped off simultaneously, and the scraped powder waste slides out of the guide groove 42 along the inclined inner bottom wall of the guide groove 42 and falls onto the inner bottom wall of the storage hopper 51, so as to avoid the large amount of powder waste attached to the guide groove 42 affecting the push of the scraper 41 by the threaded rod 43.

[0028] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Figure 8 As shown, the debris collection assembly 5 includes a storage hopper 51, the top opening end of the storage hopper 51 is fixedly connected to the bottom outer arc wall of the storage box 1, and the bottom of the storage hopper 51 is set in a quadrangular pyramid shape, and a sealing plate 52 is fixedly installed on the bottom opening end of the storage hopper 51 by bolts, and two discharge holes 53 are relatively opened on the inner bottom wall of the storage box 1, and the two discharge holes 53 are located on the left and right sides of the grinding plate 22; In this embodiment, the grinding plate 22 is located in the storage box 1 and is in the process of reciprocating movement. Since the grinding plate 22 slides along the inner wall of the storage box 1, the powder waste on the inner wall of the storage box 1 can be scraped off, and most of the powder can be pushed into the discharge hole, and then fall into the storage hopper 51 through the discharge hole for storage. The operator does not need to perform other operations, and there is no need to set up additional hanging devices, thereby reducing the manufacturing cost of the equipment.

[0029] In a further preferred embodiment of the present invention, Figure 3 , Figure 8 and Fig. 9 As shown, two guide plates 54 are relatively fixedly installed in the left end discharge hole 53, and each guide plate 54 is arranged in an inclined shape, the top of the guide plate 54 is coplanar with the top opening edge of the left end discharge hole 53, and the bottom ends of the two guide plates 54 are gap-matched; In the present embodiment, during the movement of the grinding plate 22 to the left, due to the obstruction of the guide plate 54, the amount of gas passing through the left end discharge hole 53 is limited, and a high-pressure chamber to a certain extent can be formed at the left end of the storage box 1. At this time, another part of the gas at the left end of the storage hopper 51 passes through the gap between the bamboo piece and the grinding plate body 27 and between the bamboo piece and the inner wall of the airbag 26, and flows into the right end of the storage box 1, so that a negative pressure chamber will not be formed at the right end of the storage box 1 or a high-pressure chamber will not be formed at the left end of the storage box 1 to affect the movement of the grinding plate in the storage box 1, and various parts of the outer wall of the bamboo piece form a flowing airflow in turn to blow off the powder waste attached to the bamboo piece, without the operator having to perform other operations or setting an additional driving source, thereby reducing the production cost of the device.

[0030] In a further preferred embodiment of the present invention, Figure 2 and Fig.14As shown, the clamping assembly 6 includes a plurality of clamping blocks 62 that are L-shaped when viewed from the front, and two electric telescopic rods 61 are fixedly installed at positions corresponding to the grinding holes 23 on the left and right sides of the storage box 1, and the driving end of each electric telescopic rod 61 slides through the wall of the storage box 1, and the driving end of the electric telescopic rod 61 is fixedly connected to the outer wall of the corresponding clamping block 62 by bolts; In this embodiment, after the bamboo pieces are placed in the storage box 1, the electric telescopic rod 61 starts to push the clamps to move toward each other a corresponding distance, so that the bamboo pieces are clamped and fixed at a specific position in the storage box by the two ends of the bamboo pieces. At this time, the bamboo pieces are suspended in the storage box 1, which facilitates the polishing of the outer wall of the bamboo pieces.

[0031] In a further preferred embodiment of the present invention, Fig.14 and Fig.15 As shown, a limiting strip 63 in a U-shape is provided on the bottom side of the clamping block 62 near one end of the grinding plate 22, and a collar 64 is fixedly installed at the middle position on the inner bottom wall of the limiting strip 63 where the clamping block 62 is connected to the inner wall of the corresponding limiting strip 63, and a second spring 65 is provided between the limiting strip 63 and the inner wall of the corresponding clamping block 62 where the clamping block 62 is connected to the inner wall of the corresponding collar 64, and the two ends of the second spring 65 are respectively fixedly connected to the corresponding limiting strip 63 and the inner wall of the corresponding clamping block 62; In this embodiment, after the operator puts the bamboo pieces into the storage box 1, the bamboo pieces are stably placed at corresponding positions in the storage box 1 due to the mutual interference between the two ends of the bamboo pieces and the limiting strips 63, which facilitates the loading operation of the bamboo pieces. During the movement of the above-mentioned grinding plate 22, when the grinding plate 22 moves to the position of the limit strip 63, due to the mutual interference between the grinding plate 22 and the limit strip 63 and the mutual interference between the inner wall of the ring 64 and the clamping block 62, the limit strip 63 is gradually moved away from the bottom side of the bamboo piece, which will not affect the grinding operation of the outer walls at both ends of the bamboo piece.

[0032] Working principle: When the improved bamboo chip roughing device for bamboo board processing is used, the operator first holds the handle of the cover 21 to lift the front end of the cover 21 to release the blocking state of the top opening of the storage box 1, and then the operator inserts the bamboo chip into the storage box 1 from the top opening of the storage box 1 in turn, and makes the bamboo chip pass through a plurality of grinding holes 23 in turn, and then lifts the bamboo chip upward through the deformation of the grinding plate body 27, and at the same time starts the electric telescopic rod 61 to push the clamping plate to move toward each other by a corresponding distance, so that the limit plate is pushed to move below the two ends of the bamboo chip through the spring and the buckle, and then the operator releases the bamboo chip, and the bamboo chip automatically moves downward due to the action of its own gravity. At this time, due to the mutual interference between the two ends of the bamboo chip and the inner wall of the limit strip 63, the bamboo chip is stably placed in the corresponding position in the storage box 1, and then the electric telescopic rod 61 is started again to push the two clamping blocks 62 to move toward each other by a corresponding distance, and then the position of the bamboo chip in the storage box 1 is locked by the clamping of the bamboo chip by the two clamping blocks 62; After the above-mentioned bamboo chip loading operation is completed, the driver 44 starts to drive the threaded rod 43 to rotate forward. Due to the mutual interference between the scraper 41 and the inner wall of the guide groove 42, the rotating threaded rod 43 drives the scraper 41 to move rightward along the guide groove 42 in a linear trajectory. The moving scraper 41 will first pull the piston plate 32 to the right through the pull rod 34. At this time, due to the friction between the grinding plate 22 and the inner wall of the storage box 1 and the cover 21, the pull rod 34 will first drive the piston plate 32 located in the gas storage tank 31 to slide rightward and push the gas storage tank 31. At this time, part of the gas in the gas storage tank 31 flows into the airbag 26 through the connecting hole 33, so that the air pressure in the airbag 26 and the gas storage tank 31 increases. At this time, the airbag 26 expands due to the push of the gas in the airbag 26, and the expanded airbag 26 pushes the grinding plate body 27 toward the bamboo piece. Due to the friction deformation between the grinding plate body 27 and the bamboo piece and the friction deformation between the grinding plate body 27, several grinding plates in the same grinding hole 23 cooperate with each other to form corresponding square ring-shaped annular grinding surfaces according to the processed bamboo piece and fit with the outer wall of the bamboo piece; When the piston plate 32 slides to the right, it compresses the first spring 36 until the thrust of the first spring 36 on the grinding plate 22 exceeds the friction between the grinding plate 22 and the inner wall of the storage box 1 and the friction between the grinding plate 22 and the bottom side of the cover 21, as well as the friction between the grinding plate body 27 and the bamboo piece. At this time, the piston plate 32 continues to move to the right and pushes the grinding plate 22 to slide slowly to the right, while the grinding plate body 27 slides against the outer wall of the bamboo piece, grinding the burrs on the outer wall of the bamboo piece into powder particles. It should be noted that the grinding plate 22 moving rightward can push the gas at the right end of the storage box 1 to slowly pass through the discharge hole 53 at the right end and flow into the storage hopper 51, and then flow from the discharge hole 53 at the left end to the left end of the storage box 1, so as to avoid the formation of a high-pressure chamber at the right end of the storage box 1 to affect the movement of the grinding plate 22 in the storage box 1; It should be noted that when the piston plate 32 moves slowly to the right, the external gas simultaneously flows into the gas storage tank 31 from the gas inlet hole, so that no negative pressure cavity or high pressure cavity is formed between the left side of the piston plate 32 and the inner wall of the gas storage tank 31 to affect the movement of the piston plate 32 in the gas storage tank 31; After the grinding plate 22 moves to the rightmost end of the bamboo piece, the driver 44 drives the threaded rod 43 to rotate in the opposite direction, thereby pushing the scraper 41 to move leftward along the guide groove 42. Due to the friction between the grinding plate 22 and the inner wall of the storage box 1 and the friction between the grinding plate 22 and the bottom side of the cover 21, as well as the push of the piston plate 32 by the first spring 36, the scraper 41 moving leftward will first drive the piston plate 32 to slide in the air storage tank 31 through the pull rod 34. As the piston plate 32 is reset, the space between the right side of the piston plate 32 and the inner wall of the air storage tank 31 is expanded. Since there is no inflow of external gas, a negative pressure cavity of corresponding strength is formed between the right side of the piston plate 32 and the inner wall of the air storage tank 31 and in the airbag 26. The contracted airbag 26 pulls the grinding plate body 27 away from the bamboo piece, thereby forming a gap of a certain size between the bamboo piece and the grinding plate body 27 and between the bamboo piece and the inner wall of the airbag 26. After the piston plate 32 sliding to the left in the gas storage tank 31 contacts the inner wall of the gas storage tank 31, the piston plate 32 which continues to move to the left pushes the grinding plate 22 to slide to the left quickly. At this time, due to the push of the grinding plate 22 on the gas at the left end of the storage box 1, part of the gas at the left end of the storage box 1 flows into the storage hopper 51 through the discharge hole 53 at the left end. Then, the gas in the storage hopper 51 flows into the right end of the storage box 1 from the discharge hole 53 at the right end. At the same time, due to the blocking of the guide plate 54, The amount of gas passing through the left end discharge hole 53 is limited, and another part of the gas at the left end of the storage hopper 51 passes through the gap between the bamboo piece and the grinding plate body 27 and between the bamboo piece and the inner wall of the air bag 26, and flows into the right end of the storage box 1, so that the right end of the storage box 1 does not form a negative pressure cavity or the left end of the storage box 1 forms a high pressure cavity to affect the movement of the grinding plate in the storage box 1, and each part of the outer wall of the bamboo piece forms a flowing airflow in turn to blow off the powder waste attached to the bamboo piece; During the movement of the grinding plate 22, when the grinding plate 22 moves to the position of the limit strip 63, due to the mutual interference between the grinding plate 22 and the limit strip 63 and the mutual interference between the inner wall of the ring 64 and the clamping block 62, the limit strip 63 gradually moves away from the bottom side of the bamboo piece, which will not affect the grinding operation of the outer walls at both ends of the bamboo piece. The gas flowing out from the gaps between the bamboo piece and the grinding plate body 27 and between the bamboo piece and the inner wall of the airbag 26 flows into the larger space at the right end of the storage box 1, so that the flow rate of the outflowing airflow drops rapidly. After blowing the powder waste on the bamboo piece down, the airflow will not continue to blow up a large amount of powder waste, and the powder waste will directly fall onto the inner bottom wall of the storage box 1 due to the effect of the powder waste's own gravity. When the scraper 41 slides in the guide groove 42, the scraper 41 slides along the inner wall of the guide groove 42, so that the powder waste attached to the inner wall of the guide groove 42 can be scraped off, and the scraped powder waste slides out of the guide groove 42 along the inclined inner bottom wall of the guide groove 42 and falls onto the inner bottom wall of the storage hopper 51; When the grinding plate 22 is in the process of moving in the storage box 1, the grinding plate 22 slides against the inner wall of the storage box 1, thereby scraping off the powder waste on the inner wall of the storage box 1, and pushing most of the powder into the discharge hole, and then passing through the discharge hole along the inclined guide plate 54 and falling into the storage hopper 51 for storage; It should be noted that the gas flowing in the storage hopper 51 has a relatively large space and a relatively small amount of flowing gas, which makes the gas flow rate in the storage hopper 51 extremely slow. As a result, the gas flowing in the storage hopper 51 will hardly bring the powder waste stored in the storage hopper 51 back into the storage box 1. A certain amount of water may be filled in the storage hopper 51, and the powder waste may be retained and stored in the storage hopper 51 by the adhesion of the water. According to the above, the burrs on multiple bamboo pieces are removed at one time by the reciprocating movement of the grinding plate 22 in the storage box 1. After the deburring operation of the bamboo pieces is completed, the electric telescopic rod 61 contracts and reversely pulls the clamping block 62 to reset, releasing the clamping and positioning operation of the bamboo pieces. Then, the operator releases the closed state of the top opening of the storage box 1 according to the above, and then the operator pulls the bamboo pieces out of the grinding holes 23, and the deburred bamboo pieces can be directly taken out of the storage box 1 through the top opening of the storage box 1. When the storage amount of powder waste in the above-mentioned storage hopper 51 is too much, the operator places the powder waste storage device under the bottom opening of the storage hopper 51, and then the operator unscrews the bolts on the sealing plate 52, and then directly removes the sealing plate 52 from the storage hopper 51. The powder waste in the storage hopper 51 can slide out from the bottom opening of the storage hopper 51 along the inner wall of the storage hopper 51 and fall into the powder waste storage device.
