Technical Field

[0001] This invention relates to the technical field of bamboo deburring equipment, and more particularly to a bamboo strip rough edge polishing device for bamboo board processing. Background Technology

[0002] Bamboo boards are made from finely processed bamboo strips that are glued and pressed together. After the bamboo strips are made, the surface of the bamboo strips often has rough edges. Generally, rough edges are removed by a rough edge polishing device to make the surface of the bamboo strips smoother, so as to avoid the burrs on the surface of the bamboo strips affecting the interlocking between the bamboo strips or affecting the use of the bamboo board.

[0003] Existing bamboo strip rough edge polishing devices generally use a drive roller to move the bamboo strip along a fixed trajectory, and then use rotating sandpaper or polishing rollers to polish each surface of the bamboo strip in sequence. Because the rough edges of bamboo strips are thin and have high toughness, during the polishing operation, the small rough edges at the corners of the bamboo strips may bend and deform due to the resistance of external objects, shifting to one side of the adjacent surface, affecting the polishing effect of the bamboo strip rough edges.

[0016] The present application has at least the following advantages:

[0017] 1、The improved bamboo flake burr polishing device for bamboo board processing adjusts the positions of the grinding plate bodies through the expansion of the air bag during use, so that the grinding plate bodies and the bamboo flake are in contact and deformed, and the grinding plate bodies are in contact with each other, a corresponding square ring-shaped polishing surface is formed according to the shape of the bamboo flake, and then the polishing operation of the burrs on the four surfaces of the bamboo flake is sequentially and synchronously completed in the process of slowly moving the polishing plate to the right, the burrs on the outer wall of the bamboo flake are removed, and the polishing operation of the outer wall of the bamboo flake is synchronously completed, so as to avoid the bending of the burrs on the edges and corners of the bamboo flake affecting the polishing effect of the burrs of the bamboo flake.

[0018] 2、In the process of moving the above-mentioned polishing plate to the left, the air bag is synchronously contracted, the contracted air bag moves the grinding plate bodies away from the bamboo flake, so that a gap of a certain size is formed between the bamboo flake and the grinding plate bodies and between the bamboo flake and the inner wall of the air bag, and in the process of quickly moving the polishing plate to the left, the left end gas in the storage box 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 in the storage box flows into the right end of the storage box through the gap, so that airflows of a certain intensity are sequentially formed at each position near the outer wall of the bamboo flake, the powder waste attached to the bamboo flake is blown off, the cleaning of the powder waste on the outer wall of the bamboo flake is automatically completed, and the polishing operation of the burrs of the bamboo flake and the polishing effect of the outer wall of the bamboo flake are avoided.

[0019] 3. The gas flowing out from the gaps flows into the larger space at the right end of the storage box, causing the outflowing airflow to immediately drop until it almost stops flowing. This prevents the airflow from blowing up a large amount of powder waste after it has blown it off the bamboo strips. Due to the weight of the powder waste itself, it falls directly onto the inner bottom wall of the storage box. As the grinding plate moves back and forth inside the storage box, it slides against the inner wall of the storage box, pushing away the powder waste adhering to the inner wall. Together with the debris collection component, most of the powder waste is removed from the storage box and collected in a specific location for storage. Ultimately, the device can perform a certain degree of self-cleaning, reducing the frequency of cleaning the storage box by the staff and reducing the labor intensity of the staff.

DETAILED DESCRIPTION

[0037] In order to make the technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0038] The present application provides a technical solution: refer to Figure 1 - Figure 15The application discloses a bamboo chip burr polishing device for bamboo board processing, which comprises a storage box 1 fixedly arranged on two supporting legs, a polishing assembly 2 arranged on the top side of the storage box 1 and in the storage box 1, the polishing assembly 2 comprising a cover 21 arranged on the top side of the storage box 1, a polishing plate 22 arranged in the storage box 1, and the outer peripheral wall of the polishing plate 22 being in contact with the inner wall of the storage box 1 and the bottom side of the cover 21, a plurality of polishing holes 23 being equidistantly arranged on the polishing plate 22, a ring-shaped groove 24 being arranged on the outer peripheral wall of the polishing plate 22, a sealing ring 25 being arranged in the ring-shaped groove 24 and being in contact with the inner wall of the storage box 1, the bottom side of the polishing plate 22 and the inner wall of the ring-shaped groove 24, an air bag 26 in the shape of a ring being fixedly and penetratingly arranged in the polishing hole 23, four grinding plate bodies 27 being fixedly and oppositely arranged on the inner ring wall of the air bag 26, and the adjacent two grinding plate bodies 27 being gap matched, and the grinding plate body 27 being a sponge sandpaper.

[0039] An adjusting mechanism 3 is arranged in the plate wall of the polishing plate 22, a driving mechanism 4 is arranged at the front and rear ends of the polishing plate 22, a debris collecting assembly 5 is arranged at the bottom end of the storage box 1, and a plurality of clamping assemblies 6 are oppositely arranged at the two ends of the storage box 1.

[0040] In the embodiment, when the improved bamboo chip burr polishing device for bamboo board processing is used, first, an operator holds the handle of the cover 21 and lifts the front end of the cover 21 to remove the plugging state of the top end opening of the storage box 1, then the operator sequentially inserts bamboo chips into the storage box 1 from the top end opening of the storage box 1, and makes the bamboo chips sequentially pass through the plurality of polishing holes 23, then the clamping assembly 6 is used to clamp and position the bamboo chips, and the feeding operation of the bamboo chips is completed.

[0041] After the feeding operation of the bamboo chips is completed, the operator reversely rotates the cover 21, the bottom side of the cover 21 is recombined with the top end of the storage box 1 to reseal the top end opening of the storage box 1, then the driving mechanism 4 is started, the driving mechanism 4 cooperates with the adjusting mechanism 3 to pull the polishing plate 22 in the storage box 1 to slide to the right, first, the adjusting mechanism 3 injects a specific amount of gas into the air bag 26, as the air bag 26 expands, the air bag 26 pushes the grinding plate bodies 27 towards the bamboo chips, due to the deformation of the grinding plate bodies 27 and the mutual deformation of the grinding plate bodies 27, the plurality of grinding plates in the same polishing hole 23 are mutually matched to form a corresponding square ring-shaped polishing surface according to the processing of the bamboo chips, and the polishing surface is tightly combined with the outer wall of the bamboo chips, so that in the process of continuously and slowly moving the polishing plate 22 to the right, the polishing surface is combined with the outer wall of the bamboo chips to slide, and the polishing operation of the burr of the bamboo chips is completed.

[0042] After the polishing plate 22 moves to the right end of the bamboo sheet, the driving mechanism 4 drives the polishing plate 22 to slide quickly to the left in the storage box 1 in cooperation with the adjusting mechanism 3, first, the gas in the air bag 26 is extracted, the air bag 26 is contracted to move the grinding plate body 27 away from the bamboo sheet, so that a gap of a certain size is formed between the bamboo sheet and the grinding plate body 27 and the inner wall of the air bag 26, and in the process of the quick left movement of the polishing plate 22, the gas in 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 in the left end of the storage box 1 flows into the right end of the storage box 1 through the gap, so that an airflow of a certain intensity is formed at each position near the outer wall of the bamboo sheet in turn, the powder waste attached to the bamboo sheet is blown off, and the gas flowing out of the gap immediately decreases in flow rate due to the larger space in the right end of the storage box 1, until the flow rate of the airflow is zero. After the airflow blows off the powder waste on the bamboo sheet, it will not continue to blow a large amount of powder waste, and due to the action of the gravity of the powder waste, the powder waste directly falls to the inner bottom wall of the storage box 1, and finally the burrs on the outer wall of the bamboo sheet are removed through the reciprocating movement of the polishing plate 22, and the polishing operation of the outer wall of the bamboo sheet is completed synchronously.

[0043] In the process of reciprocating movement of the above-mentioned polishing plate 22, the polishing plate 22 slides along the inner wall of the storage box 1, so as to push the powder waste attached to the inner wall of the storage box 1, and cooperate with the debris collecting assembly 5 to clean out most of the powder waste from the storage box 1 and store the powder waste in a specific position, and the device has high degree of automation.

[0044] In a further preferred embodiment of the present application, as shown in Figure 1 the bottom side of the cover 21 is in contact with the top side of the storage box 1, the rear end of the cover 21 is hingedly arranged with the storage box 1, the front end of the cover 21 is fixedly connected with the storage box 1 through buckling, and the cover 21 is made of a transparent plate;

[0045] In the embodiment, when the burr of the bamboo sheet is polished, the operator can observe the polishing state of the burr of the bamboo sheet in the storage box 1 through the cover 21, so as to avoid over-polishing of the bamboo sheet or residual burr on the outer wall of the bamboo sheet, so as to ensure the processing effect of the bamboo sheet.

[0046] In a further preferred embodiment of the present application, as shown in Figure 2 , Figure 10 , Figure 11 and Figure 12As shown, the adjusting mechanism 3 comprises a piston plate 32 arranged in a ring shape, a plurality of gas storage grooves 31 are formed in the plate wall of the polishing plate 22, and the gas storage grooves 31 are arranged at the intermediate position of the outer circumferential side of the polishing hole 23, the piston plate 32 is arranged in the gas storage groove 31, and the inner and outer ring walls of the piston plate 32 are in contact with the inner wall of the gas storage groove 31, the inside of the air bag 26 is connected with the inside of the gas storage groove 31 through a plurality of connecting holes 33, two pull rods 34 are arranged at the intermediate position of the right side of the polishing plate 22 in a sliding manner, and the left end of each pull rod 34 is inserted into the gas storage groove 31 and fixedly connected with the piston plate 32, a sealing ring 35 is fixedly arranged at the position corresponding to the pull rod 34 in the plate wall of the polishing plate 22, and the inner ring wall of the sealing ring 35 is in contact with the outer circumferential wall corresponding to the pull rod 34, a plurality of air inlet holes 37 are formed at the position corresponding to the gas storage groove 31 on the left side of the polishing plate 22, and the inside of each air inlet hole 37 is communicated with the inside of the gas storage groove 31;

[0047] In the embodiment, when the driving mechanism 4 pulls the polishing plate 22 to the right, the piston plate 32 is first pulled to the right through the pull rod 34. At this time, due to the friction between the polishing plate 22 and the inner wall of the storage box 1 and the cover 21, the pull rod 34 first drives the piston plate 32 to slide to the right in the gas storage groove 31 and pushes the gas in the gas storage groove 31. At this time, part of the gas in the gas storage groove 31 flows into the air bag 26 through the connecting hole 33, so that the air pressure in the air bag 26 and the gas storage groove 31 rises. At this time, the air bag 26 expands due to the pushing of the gas in the air bag 26, and the expanded air bag 26 pushes the grinding plate body 27 in the direction of the bamboo piece. Due to the resistance deformation of the grinding plate body 27 and the bamboo piece and the mutual resistance deformation of the grinding plate body 27, a plurality of grinding plates in the same polishing hole 23 cooperate with each other to form a corresponding annular polishing surface in the form of a square ring according to the processing of the bamboo piece and are in close contact with the outer wall of the bamboo piece. Without the need for other operations by the operator or the need to set up an additional driving source, the manufacturing cost of the device is reduced.

[0048] In a further preferred embodiment of the present application, as shown in Figure 11 and Figure 13 A plurality of first springs 36 are arranged between the piston plate 32 and the inner wall of the gas storage groove 31, and the two ends of each first spring 36 are fixedly connected with the piston plate 32 and the inner wall of the gas storage groove 31, respectively. The plurality of first springs 36 are divided into two groups and arranged on the upper and lower sides of the connecting hole 33, and the spacing between adjacent two first springs 36 in each group is equal.

[0049] When the driving mechanism 4 pushes the grinding plate 22 to the left in this embodiment, 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, and the pushing of the piston plate 32 by the first spring 36, first push the rod 34 to slide the piston plate 32 in the gas storage groove 31 to the left. When the piston plate 32 is reset, the space between the right side of the piston plate 32 and the inner wall of the gas storage groove 31 is enlarged, and because 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 gas storage groove 31 and in the air bag 26. The contracted air bag 26 pulls the grinding plate body 27 away from the bamboo chips, so that a gap of a certain size is formed between the bamboo chips and the grinding plate body 27 and between the bamboo chips and the inner wall of the air bag 26. No other operation is needed by the operator, and no additional driving source is needed, which reduces the manufacturing cost of the device.

[0050] In further preferable embodiments of the present application, as shown in Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , the driving mechanism 4 includes two drivers 44. The right end of the rod 34 is fixedly provided with a scraper 41 by bolts. A guide groove 42 is formed on the inner wall of the storage box 1 at a position corresponding to the scraper 41. 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 threadedly and rotatably arranged on the scraper 41. The two ends of the threaded rod 43 are rotatably connected to the wall of the storage box 1. The drivers 44 are fixedly arranged on the right side of the storage box 1 at positions corresponding to the threaded rods 43. The driving ends of the drivers 44 are fixedly connected to the right ends of the corresponding threaded rods 43.

[0051] In this embodiment, when the driving mechanism 4 drives the grinding plate 22 to slide left and right in the storage box 1, the drivers 44 first drive the threaded rods 43 to rotate forward or reversely. Because of the mutual resistance of the inner wall of the guide groove 42, the scraper 41 moves linearly along the inner wall of the guide groove 42 to reciprocate in the guide groove 42.

[0052] In further preferable embodiments of the present application, as shown in Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the inner bottom wall of the guide groove 42 is obliquely arranged. The cross-sectional shape of the reverse end of each scraper 41 is trapezoidal. The part of each scraper 41 in the corresponding guide groove 42 is located at the joint of the inner wall of the corresponding guide groove 42.

[0053] In the embodiment, the scraper 41 can scrape the powder waste adhered to the inner wall of the guide groove 42 synchronously during the sliding of the scraper 41 in the guide groove 42, 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 on the inner bottom wall of the storage hopper 51, so that the powder waste adhered to the guide groove 42 does not affect the pushing of the threaded rod 43 to the scraper 41.

[0054] In further preferable embodiments of the present application, as shown in Figure 3 、 Figure 6 and Figure 8 , the debris collecting assembly 5 comprises a storage hopper 51, the top open end of the storage hopper 51 is fixedly connected with the bottom outer arc wall of the storage box 1, the bottom of the storage hopper 51 is provided in a quadrangular pyramid shape, the bottom open end of the storage hopper 51 is provided with a sealing plate 52 fixedly installed through bolts, two discharge holes 53 are oppositely provided 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 polishing plate 22.

[0055] In the embodiment, during the reciprocating movement of the polishing plate 22 in the storage box 1, the polishing plate 22 slides along the inner wall of the storage box 1, so that the powder waste on the inner wall of the storage box 1 is scraped off, and most of the powder is pushed into the discharge hole and then falls into the storage hopper 51 through the discharge hole, without the need for other operations by the operator or the need for the setting of an additional material hanging device, thereby reducing the manufacturing cost of the equipment.

[0056] In further preferable embodiments of the present application, as shown in Figure 3 、 Figure 8 and Figure 9 , two material guide plates 54 are oppositely fixedly installed in the left discharge hole 53, and each material guide plate 54 is provided in an inclined shape, the top end of the material guide plate 54 is coplanar with the top open end of the left discharge hole 53, and the bottom ends of the two material guide plates 54 are gap-fitted.

[0057] In the embodiment, during the left movement of the polishing plate 22, the left end of the storage box 1 can form a high-pressure cavity to a certain extent due to the limited amount of gas passing through the left end discharge hole 53 blocked by the material guide plates 54, at this time, another part of the gas in the left end of the storage hopper 51 passes through the gaps between the bamboo sheet and the grinding plate body 27 and between the bamboo sheet 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 the flowing gas is sequentially formed on each part of the outer wall of the bamboo sheet to blow off the powder waste adhered to the bamboo sheet, without the need for other operations by the operator or the need for the setting of an additional driving source, thereby reducing the production cost of the device.

[0058] In further preferable embodiments of the present application, as shown in Figure 2 andFigure 14 As shown in the figure, the clamping assembly 6 comprises several clamping blocks 62 arranged in L-shaped shape, two electric telescopic rods 61 are fixedly arranged at the positions corresponding to the polishing holes 23 on the left and right sides of the storage box 1, and the driving end of each electric telescopic rod 61 is slidably penetrated through the wall of the storage box 1, and the driving end of the electric telescopic rod 61 is fixedly connected with the outer wall of the corresponding clamping block 62 through bolts.

[0059] In the embodiment, after the bamboo pieces are placed in the storage box 1, the electric telescopic rod 61 is started to push the clamping plate to move towards each other by a corresponding distance, so that the bamboo pieces are clamped and fixed in the storage box at a specific position from both ends of the bamboo pieces. At this time, the bamboo pieces are suspended in the storage box 1, which facilitates the polishing process of the outer wall of the bamboo pieces.

[0060] In a further preferred embodiment of the present application, as shown in Figure 14 and Figure 15 The bottom side of the clamping block 62 close to one end of the polishing plate 22 is provided with a limiting strip 63 arranged in U-shaped shape, and a sleeve ring 64 is fixedly arranged at the middle position on the inner bottom wall of the limiting strip 63 at the joint between the clamping block 62 and the inner wall of the corresponding limiting strip 63. A second spring 65 is arranged between the inner wall of the corresponding limiting strip 63 and the inner wall of the corresponding clamping block 62 at the joint between the clamping block 62 and the inner wall of the corresponding sleeve ring 64, and the two ends of the second spring 65 are fixedly connected with the inner wall of the corresponding limiting strip 63 and the inner wall of the corresponding clamping block 62, respectively.

[0061] In the embodiment, after the bamboo pieces are placed in the storage box 1, the bamboo pieces are stably placed in the corresponding position in the storage box 1 due to the mutual resistance of the two ends of the bamboo pieces and the limiting strip 63, which facilitates the feeding operation of the bamboo pieces.

[0062] During the movement of the polishing plate 22, when the polishing plate 22 moves to the position of the limiting strip 63, the limiting strip 63 is gradually moved away from the bottom side of the bamboo pieces due to the mutual resistance between the polishing plate 22 and the limiting strip 63 and the mutual resistance between the inner wall of the sleeve ring 64 and the clamping block 62, which does not affect the polishing operation of the outer wall of the two ends of the bamboo pieces.

[0063] Working principle: the improved bamboo board processing with bamboo edge polishing device in use, first operator hand seal cover 21 handle the front end of the cover 21 to lift up to remove the storage box 1 top opening plugging state, then the operator in turn from the top opening of the storage box 1 into the storage box 1, and make the bamboo sheet in turn through several polishing hole 23, then through the deformation of the grinding plate body 27 to lift the bamboo sheet, at the same time start the electric telescopic rod 61 push the clamp plate corresponding distance moving towards, so as to push the spring and buckle limit plate moves to the both ends of the bamboo sheet below, then the operator loose bamboo sheet, due to the gravity of the bamboo sheet itself, the bamboo sheet is automatically moved down, this time due to the mutual resistance of the bamboo sheet both ends and the inner wall of the limiting strip 63, the bamboo sheet is stably placed in the corresponding position in the storage box 1, then the electric telescopic rod 61 is started again, the two clamping blocks 62 move towards the corresponding distance, and then the two clamping blocks 62 lock the position of the bamboo sheet in the storage box 1;

[0064] After the above-mentioned bamboo sheet feeding operation is completed, the driver 44 is started to drive the threaded rod 43 to rotate forward, and due to the mutual resistance of the scraper 41 and the inner wall of the guide groove 42, the rotating threaded rod 43 drives the scraper 41 to move along the guide groove 42 to the right 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 polishing 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 to slide to the right in the gas storage groove 31, pushing the gas in the gas storage groove 31. At this time, part of the gas in the gas storage groove 31 flows into the air bag 26 through the connecting hole 33, causing the air pressure in the air bag 26 and the gas storage groove 31 to rise. At this time, the air bag 26 expands due to the push of the gas in the air bag 26, and the expanded air bag 26 pushes the grinding plate body 27 towards the bamboo sheet. Due to the resistance of the grinding plate body 27 and the bamboo sheet, and the mutual resistance of the grinding plate body 27, the several grinding plates in the same polishing hole 23 cooperate to form a corresponding square ring-shaped annular polishing surface according to the processing of the bamboo sheet and are in close contact with the outer wall of the bamboo sheet.

[0065] The above-mentioned piston plate 32 slides to the right, compressing the first spring 36, until the pushing force of the first spring 36 on the polishing plate 22 exceeds the friction between the polishing plate 22 and the inner wall of the storage box 1, the friction between the polishing plate 22 and the bottom side of the cover 21, and the friction between the grinding plate body 27 and the bamboo sheet. At this time, the piston plate 32 continues to move to the right, pushing the polishing plate 22 to slide slowly to the right, while the grinding plate body 27 slides in close contact with the outer wall of the bamboo sheet, polishing the burrs on the outer wall of the bamboo sheet into powdery particles.

[0066] It should be noted that the above-mentioned right-moving polishing plate 22 can push the gas in the right end of the storage box 1 to flow slowly through the right end of the discharge hole 53 into the storage hopper 51, and then flow from the left end of the discharge hole 53 into the storage box 1 to avoid the formation of a high-pressure chamber at the right end of the storage box 1, which affects the movement of the polishing plate 22 in the storage box 1.

[0067] It should be noted that when the piston plate 32 moves slowly to the right, the external gas flows into the gas storage groove 31 synchronously through 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 groove 31, which affects the movement of the piston plate 32 in the gas storage groove 31;

[0068] After the abrading plate 22 moves to the right end of the bamboo piece, the driver 44 drives the threaded rod 43 to rotate reversely, so as to push the scraper 41 to move leftward along the guide groove 42. Due to the friction between the abrading plate 22 and the inner wall of the storage box 1 and the friction between the abrading plate 22 and the bottom side of the cover 21, and the pushing of the piston plate 32 by the first spring 36, the leftward moving scraper 41 will first drive the piston plate 32 to slide in the gas storage groove 31 through the pull rod 34. With the reset of the piston plate 32, the space between the right side of the piston plate 32 and the inner wall of the gas storage groove 31 is expanded, and due to 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 gas storage groove 31 and in the air bag 26. The contracted air bag 26 pulls the abrading plate body 27 away from the bamboo piece, so that a gap of a certain size is formed between the bamboo piece and the abrading plate body 27 and between the bamboo piece and the inner wall of the air bag 26;

[0069] After the piston plate 32 in the gas storage groove 31 slides leftward and abuts against the inner wall of the gas storage groove 31, the piston plate 32 continuously moving leftward pushes the abrading plate 22 to slide leftward quickly. At this time, due to the pushing of the abrading plate 22 to 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 left end discharge hole 53, and then the gas in the storage hopper 51 flows into the right end of the storage box 1 through the right end discharge hole 53. At the same time, due to the blockage of the left end discharge hole 53 by the guide plate 54, another part of the gas in the storage hopper 51 flows into the right end of the storage box 1 through the gap between the bamboo piece and the abrading plate body 27 and between the bamboo piece and the inner wall of the air bag 26, so that no negative pressure cavity is formed at the right end of the storage box 1 or no high pressure cavity is formed at the left end of the storage box 1, which affects the movement of the abrading plate in the storage box 1, and the flowing gas is formed at each position on the outer wall of the bamboo piece in turn, so as to blow the powder waste attached to the bamboo piece down;

[0070] During the movement of the abrading plate 22, when the abrading plate 22 moves to the position of the limiting strip 63, the limiting strip 63 gradually moves away from the bottom side of the bamboo piece due to the mutual abutment of the abrading plate 22 and the limiting strip 63 and the mutual abutment of the inner wall of the sleeve ring 64 and the clamping block 62, which does not affect the abrading operation of the outer walls of the two ends of the bamboo piece;

[0071] The gas flowing out of the gap between the bamboo sheet and the grinding plate body 27 and the gap between the bamboo sheet and the inner wall of the air bag 26 will flow into the larger space at the right end of the storage box 1, so that the flow rate of the outflowing gas will rapidly decrease. After the powder waste on the bamboo sheet is blown off, the gas will not continue to blow a large amount of powder waste, and the powder waste will directly fall to the inner bottom wall of the storage box 1 due to the action of its own gravity.

[0072] During the sliding of the scraper 41 in the guide groove 42, the powder waste adhering to the inner wall of the guide groove 42 can be scraped off because the scraper 41 slides along the inner wall of the guide groove 42. The scraped powder waste slides out of the guide groove 42 along the inclined inner bottom wall of the guide groove 42 and falls to the inner bottom wall of the storage hopper 51.

[0073] During the movement of the grinding plate 22 in the storage box 1, the powder waste on the inner wall of the storage box 1 can be scraped off because the grinding plate 22 slides along the inner wall of the storage box 1. Most of the powder is pushed into the discharge hole and then falls into the storage hopper 51 through the inclined guide plate 54 along the discharge hole.

[0074] It should be noted that the gas flowing in the storage hopper 51 will be extremely slow due to the large space in the storage hopper 51 and the small amount of flowing gas, which will eventually make the gas flowing in the storage hopper 51 almost unable to bring the powder waste stored in the storage hopper 51 back into the storage box 1. A certain amount of water can also be filled in the storage hopper 51 to trap the powder waste in the storage hopper 51 by the adhesion of water.

[0075] According to the above, the burrs on the plurality of bamboo sheets are removed at one time by the reciprocating movement of the grinding plate 22 in the storage box 1. After the burring operation of the bamboo sheets is completed, the electric telescopic rod 61 is retracted to pull the clamping block 62 back to its original position, thereby releasing the clamping and positioning operation of the bamboo sheets. Then, the operator releases the closed state of the opening at the top end of the storage box 1, and then the operator pulls the bamboo sheet out of the grinding hole 23, so that the bamboo sheet with the burring operation completed can be taken out of the storage box 1 through the opening at the top end of the storage box 1.

[0076] When the storage amount of the powder waste in the storage hopper 51 is too much, the operator places the powder waste storage device below the bottom opening of the storage hopper 51, then 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 of 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.
