Description

Technical Field

[0001] The invention belongs to the technical field of plate stacking machines, in particular to a device for continuous automatic stacking of card strips. Background Art

[0002] Pallet strips are a kind of plate-shaped paper shell used to separate and position products. When processing pallet strips, several pallet strips are cut into the same specifications through the production line, and then uniformly stacked by palletizing equipment, so that several pallet strips can be stacked together for packaging and transportation.

[0003] When processing the pallet strips, they will go through a cutting step, through which several pallet strips are cut into the required specifications, so as to facilitate uniform palletizing. When palletizing the pallet strips, the existing palletizing equipment transports the pallet strips in a single layer to the stacking machine station, and the pallet strip products are clamped by the clamping mechanism of the stacking machine; at this time, the next layer of products enters the stacking machine, and by loosening the clamping mechanism of the stacking machine, the clamped products fall onto the products of the stacking machine, and so on, until the required height is reached.

[0004] Since burrs will remain during cutting, and most cutting equipment cannot remove the remaining burrs in time, more burrs will remain around the pallet strips. The remaining burrs will make the edges of the pallet strips uneven, resulting in loose contact between layers when stacking multiple layers, forming potential gaps or misalignments, thereby reducing the overall stability of the pallet, causing tilting or collapse during handling or transportation, causing damage to the goods or safety accidents. At the same time, after the palletizing operation is completed, the pallet strips will be wrapped and fixed with a film. Since there are residual burrs around the pallet strips, it is easy to puncture the film, making it difficult for the film to effectively restrain and fix the pallet strips. When encountering bumps during transportation, the stacked pallet strips are also prone to tipping over.

[0005] To this end, the present invention provides a device for continuously and automatically stacking pallet strips. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A continuous automatic palletizing device for pallet strips of the present invention includes a palletizer. On both sides of the palletizer, there are brackets that move longitudinally through cylinders. On the side of the two brackets close to each other, there is a clamping plate that moves horizontally through a cylinder. On the palletizer, there is a pallet strip body. On the side of the two brackets close to each other, there are two symmetrically arranged cross plates fixedly installed, and on the cross plates, there is a positioning plate connected through a cylinder; on the palletizer, there is a cutting mechanism. The cutting mechanism includes a fixed frame fixedly connected to the palletizer. On the top of the fixed frame, there is an electric push rod fixedly installed. At the output end of the electric push rod, there is a fixed column fixedly installed. On the surface of the fixed column, there are several connecting arms fixedly installed. Inside the connecting arm, there is an extension arm that is hermetically and slidably connected. At one end of the extension arm, there is a fixing plate fixedly installed. At the bottom of the fixing plate, there is a cutting knife fixedly installed; on the top of the fixed frame, there is an air pump fixedly installed. At one end of the air pump, there are several air guide pipes fixedly installed. The ends of the several air guide pipes far away from the air pump are respectively connected to the inside of the several fixed columns.

[0008] Further, a grinding mechanism is provided inside the cutting knife. The grinding mechanism includes a grinding plate installed in the cutting knife through a spring, and the grinding plate is slidably connected to the cutting knife.

[0009] Further, a positioning mechanism is provided inside the fixed column. The positioning mechanism includes a receiving groove opened inside the fixed column. Inside the receiving groove, there is a sliding column slidably connected through several elastic members. At the bottom of the sliding column, there is a fixed disk fixedly installed.

[0010] Further, several rectangular plates are fixedly installed on the surface of the fixed disk, and at the bottom of the rectangular plate, there is a gasket made of a flexible material fixedly installed.

[0011] Further, a cleaning mechanism is provided on the fixed frame. The cleaning mechanism includes several hollow elastic blocks fixedly installed on the fixed frame. On one side of the elastic block, there is a connecting pipe fixedly installed and connected to the inside; on the fixed frame, there are four welding frames fixedly installed. On one side of the welding frame, there are two fixed cylinders fixedly installed. The two fixed cylinders are arranged vertically. Inside the fixed cylinder, there is a sliding cylinder hermetically and slidably connected. At one end of the sliding cylinder, there is a "V"-shaped cleaning plate fixedly installed. Inside the cleaning plate, there is a brush installed; the end of the connecting pipe far away from the elastic block is connected to the inside of the fixed cylinder.

[0012] Further, an extrusion assembly is provided on the connecting arm. The extrusion assembly includes an extrusion plate fixedly connected to the connecting arm. On the top of the extrusion plate, there are two symmetrically arranged and arc-shaped auxiliary plates fixedly installed.

[0013] Further, a maintenance component is arranged on the fixed disk. The maintenance component includes a plurality of hollow rubber boxes fixedly installed on the fixed disk. One side of the rubber box is fixedly installed with a liquid guide pipe, and the end of the liquid guide pipe away from the rubber box is communicated with the cleaning plate.

[0014] Further, an inverted "U"-shaped connecting rod is fixedly installed on the surface of the fixed cylinder, and the connecting rod passes through the brush.

[0015] Further, a blowing mechanism is arranged in the fixed column. The blowing mechanism includes a communicating pipe communicated with the inside of the storage groove and provided with a one-way valve. The end of the communicating pipe away from the storage groove is communicated with the palletizer. A through groove is formed on one side of the palletizer; the elastic member is a hollow elastic ball, shrinkage holes are formed on the surface of the elastic ball, the sliding column is in sealed sliding connection with the fixed column, and a pipe communicated with the inside and provided with a one-way valve is fixedly installed on one side of the fixed column.

[0016] Further, a hollow clamping plate is clamped on one side of the palletizer. A plurality of air outlets communicated with the inside are formed on the side of the clamping plate close to the main body of the clamping bar, and the end of the communicating pipe away from the storage groove is communicated with the inside of the clamping plate.

[0017] The beneficial effects of the present invention are as follows: 1. For the automatic continuous palletizing device for clamping bars of the present invention, when a plurality of main bodies of clamping bars complete the palletizing work on the palletizer, the palletized main bodies of clamping bars are waiting for transportation on the conveyor belt. At this time, first use an air pump to transport gas through a plurality of air guide pipes into a plurality of connecting arms, so as to push a plurality of extension arms in the plurality of connecting arms to move, so that the extension arms drive the fixing plate and the cutting knife to move to a suitable position, thereby facilitating adaptation to different sizes of main bodies of clamping bars and improving the adaptability of the equipment during use. Then start the electric push rod on the fixed frame. The electric push rod drives the fixed column, the connecting arm, the extension arm, the fixing plate and the cutting knife together to move towards the main body of the clamping bar through the output end. Use the end of the cutting knife to cut and remove the burrs around the main body of the clamping bar. Through the designed structure, rapid and neat palletizing of the main body of the clamping bar is realized, and at the same time, the designed cutting mechanism is used to perform deburring operations on a plurality of palletized main bodies of clamping bars. Through the deburring operation, it can effectively avoid potential gaps or misalignments caused by the uneven edges of the main body of the clamping bar, resulting in insufficient contact between layers during multi-layer stacking, thereby reducing the overall stability of the palletizing. At the same time, the deburring operation can also prevent the edge burrs from piercing the film when the film is wound around the main body of the clamping bar later, resulting in a decrease in the binding force of the film and then collapse.

[0018] 2. For a continuous automatic palletizing device for pallet strips according to the present invention, when the electric push rod drives the fixed column to move downward, the sliding column will be driven to move downward together with the fixed column, so that the fixed disk, several rectangular plates and several gaskets at the bottom of the sliding column move downward together. The fixed disk, rectangular plates and gaskets are used to press and position the pallet strip body after palletizing, so that the pallet strip body will not be displaced during subsequent cutting. By designing several rectangular plates and gaskets, the volume of the fixed disk can be reduced, so as to achieve lightweight while enabling efficient extrusion. The gasket is designed to be made of a flexible material to prevent damage to the pallet strip body during extrusion. Since the fixed column and the sliding column are slidably connected, when the fixed disk at the bottom of the sliding column has abutted against the pallet strip body, the electric push rod can still continue to drive the fixed column to slide downward, which is convenient for the cutting knife to perform cutting operations around the pallet strip body.

[0019] 3. For a continuous automatic palletizing device for pallet strips according to the present invention, when the connecting arm moves upward to squeeze several elastic blocks, the elastic blocks can be efficiently squeezed, and the gas in several elastic blocks is forced to enter the corresponding fixed cylinder through the corresponding connecting pipe after being squeezed. The gas pushes the sliding cylinder in the fixed cylinder, so that the sliding cylinder drives the cleaning plate and the brush to move towards the cutting knife. When the cleaning is completed, the elastic blocks are no longer squeezed. At this time, the gas in the fixed cylinder will flow back into the elastic blocks through the connecting pipe, and the sliding cylinder will drive the cleaning plate and the brush to follow and reset. The reset brush will continuously contact the inverted "U"-shaped connecting rod, and the connecting rod will continuously swing the brush to remove the impurities swept out by the brush, which is convenient for the efficient operation of the brush. When the cutting knife has been used for a long time, it needs to be maintained. Therefore, the bottom of the fixed column is used to squeeze several rubber boxes on the top of the fixed disk, so that the pre-stored maintenance liquid in the rubber boxes is sprayed on the brush through the liquid guide pipe. Subsequently, when the brush removes impurities from the cutting knife, the maintenance liquid on the surface will be used to perform maintenance operations on the cutting knife, thereby extending the service life of the cutting knife.

[0020] 4. For a continuous automatic palletizing device for pallet strips according to the present invention, when the fixed column slides downward towards the sliding column, several elastic members inside will be squeezed, so that the gas in the elastic members is discharged into the receiving groove of the fixed cone through the shrinkage holes, and the gas in the receiving groove enters the clamping plate through the communication pipe together, and is blown out of the air outlet hole of the clamping plate towards the conveyor belt of the palletizer, and the impurities generated after cutting on the conveyor belt are blown out through the through groove. After the gas in the elastic member is squeezed out, when it is no longer squeezed by the fixed column, it will be refilled through the pipeline, which is convenient for the next use. When all the pallet strip bodies on the palletizer are conveyed to the next process, there is no pallet strip body on the palletizer at this time. The electric push rod is started again and the above steps are repeated. At this time, due to the lack of obstruction of the pallet strip body, the gas blown out of the air outlet can comprehensively clean the palletizer, thereby reducing the influence of impurities remaining on the palletizer on the flatness of the subsequent palletizing of the pallet strip body.

Detailed Description of the Invention

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] As Figures 1 to 10 shown, a continuous automatic palletizing device for pallet strips according to an embodiment of the present invention includes a palletizer 1. Brackets 2 that move longitudinally through cylinders are installed on both sides of the palletizer 1. A clamping plate 3 that moves horizontally is connected to the side of the two brackets 2 close to each other through a cylinder. A pallet strip body 4 is arranged on the palletizer 1. Two symmetrically arranged cross plates 5 are fixedly installed on the side of the two brackets 2 close to each other. A positioning plate 6 is connected to the cross plate 5 through a cylinder; a cutting mechanism 10 is arranged on the palletizer 1. The cutting mechanism 10 includes a fixed frame 11 fixedly connected to the palletizer 1. An electric push rod 12 is fixedly installed on the top of the fixed frame 11. A fixed column 13 is fixedly installed at the output end of the electric push rod 12. A plurality of connecting arms 14 are fixedly installed on the surface of the fixed column 13. An extension arm 15 is hermetically and slidably connected inside the connecting arm 14. A fixing plate 16 is fixedly installed at one end of the extension arm 15. A cutting knife 17 is fixedly installed at the bottom of the fixing plate 16; an air pump 18 is fixedly installed on the top of the fixed frame 11. One end of the air pump 18 is fixedly installed with a plurality of air guide pipes 19. The ends of the plurality of air guide pipes 19 away from the air pump 18 are respectively communicated with the inside of the plurality of fixed columns 13.

[0026] Specifically, a grinding mechanism 20 is arranged inside the cutting knife 17. The grinding mechanism 20 includes a grinding plate 21 installed in the cutting knife 17 through a spring 22. The grinding plate 21 is slidably connected to the cutting knife 17.

[0027] During operation, the pallet strip body 4 (i.e., the thin plate) is conveyed to the palletizer 1 by a conveyor belt. At this time, the two clamping plates 3 and the two positioning plates 6 will move towards the pallet strip body 4 under the action of several cylinders and clamp it. Clamping the four sides of the pallet strip body 4 can increase stability and prevent the pallet strip body 4 from falling during the ascending and descending processes. At this time, the bracket 2 will drive the clamping plate 3, the positioning plate 6, and the pallet strip body 4 to move upward under the action of the cylinder, leaving a gap between the pallet strip body 4 and the surface of the palletizer 1, facilitating the next pallet strip body 4 to flow onto the palletizer 1. Then, by loosening the two clamping plates 3 and the two positioning plates 6, the originally clamped pallet strip body 4 falls onto the pallet strip body 4 on the palletizer 1. At this time, the fixing frame 11 drives the clamping plate 3 and the positioning plate 6 to move downward and reset, facilitating the continuous repetition of the above operations, thereby stacking several pallet strip bodies 4 to the required height and completing the palletizing operation. After the palletizing operation is completed, the conveyor belt on the palletizer 1 starts, conveying several pallet strip bodies 4 to the next process for flipping operation. After the flipping operation is completed, it enters the final film packing.

[0028] When several pallet strip bodies 4 complete the palletizing work on the palletizer 1, the palletized pallet strip bodies 4 are waiting for transportation on the conveyor belt. At this time, first use the air pump 18 to convey gas through several air ducts 19 into several connecting arms 14, thereby pushing several extension arms 15 inside the several connecting arms 14 to move, causing the extension arms 15 to drive the fixing plate 16 and the cutting knife 17 to move to a suitable position (i.e., the cutting knife 17 is aligned with the side of the pallet strip body 4, and a position sensor can be used for positioning), thus facilitating adaptation to different sizes of pallet strip bodies 4 and improving the adaptability of the equipment during use. Then start the electric push rod 12 on the fixing frame 11. The electric push rod 12 drives the fixing column 13, the connecting arm 14, the extension arm 15, the fixing plate 16, and the cutting knife 17 to move towards the pallet strip body 4 together through the output end. Use the end of the cutting knife 17 to cut and remove the burrs around the four sides of the pallet strip body 4. As the cutting knife 17 contacts the periphery of the pallet strip body 4, the internal grinding plate 21 (sandpaper can be installed on the side close to the pallet strip body 4) continuously contacts the pallet strip body 4 for fine trimming and grinding to further remove the burrs around the pallet strip body 4.

[0029] Through the above-designed structure, the rapid and neat palletizing of the pallet strip body 4 is achieved, and at the same time, the designed cutting mechanism 10 is used to perform deburring operations on several pallet strip bodies 4 after palletizing. Through the deburring operation, it can effectively avoid potential gaps or misalignments caused by the uneven edges of the pallet strip body 4, resulting in poor interlayer contact when stacked in multiple layers, thereby reducing the overall stability of the palletizing. At the same time, the deburring operation can also prevent the edge burrs from piercing the film when the film is wound around the pallet strip body 4 later, resulting in a decrease in the binding force of the film and then collapse.

[0030] A positioning mechanism 30 is arranged inside the fixed column 13. The positioning mechanism 30 includes a storage groove 31 opened inside the fixed column 13. A sliding column 33 is slidably connected inside the storage groove 31 through a plurality of elastic members 32. A fixed disk 34 is fixedly installed at the bottom of the sliding column 33. A plurality of rectangular plates 35 are fixedly installed on the surface of the fixed disk 34. A gasket 36 made of a flexible material is fixedly installed at the bottom of the rectangular plate 35.

[0031] During operation, when the electric push rod 12 drives the fixed column 13 to move downward, it will drive the sliding column 33 to move downward together through the fixed column 13, so that the fixed disk 34, a plurality of rectangular plates 35 and a plurality of gaskets 36 at the bottom of the sliding column 33 move downward together. The fixed disk 34, the rectangular plates 35 and the gaskets 36 are used to press and position the stacked pallet strip body 4, so that the pallet strip body 4 will not be displaced during subsequent cutting. By designing a plurality of rectangular plates 35 and gaskets 36, the volume of the fixed disk 34 can be reduced, so as to achieve lightweight while being able to efficiently extrude. The gasket 36 is designed to be made of a flexible material in order not to damage the pallet strip body 4 during extrusion. Since the fixed column 13 and the sliding column 33 are slidably connected, when the fixed disk 34 at the bottom of the sliding column 33 has abutted against the pallet strip body 4, the electric push rod 12 can still continue to drive the fixed column 13 to slide downward (at this time, the fixed column 13 will squeeze the internal elastic member 32, and the function of the elastic member 32 is to make the sliding column 33 be inside the fixed column 13 when not being squeezed by the fixed column 13), which is convenient for the cutting knife 17 to cut the periphery of the pallet strip body 4.

[0032] A cleaning mechanism 40 is arranged on the fixed frame 11. The cleaning mechanism 40 includes a plurality of hollow elastic blocks 41 fixedly installed on the fixed frame 11. A connecting pipe 47 communicating with the inside is fixedly installed on one side of the elastic block 41; Four welding frames 42 are fixedly installed on the fixed frame 11. Two fixed cylinders 43 are fixedly installed on one side of the welding frame 42. The two fixed cylinders 43 are arranged vertically. A sliding cylinder 44 is hermetically slidably connected inside the fixed cylinder 43. A "V"-shaped cleaning plate 45 is fixedly installed at one end of the sliding cylinder 44. A brush 46 is installed on the inner wall of the cleaning plate 45; The end of the connecting pipe 47 away from the elastic block 41 communicates with the inside of the fixed cylinder 43.

[0033] Specifically, an extrusion assembly 48 is provided on the connecting arm 14. The extrusion assembly 48 includes an extrusion plate 481 fixedly connected to the connecting arm 14. At the top of the extrusion plate 481, two symmetrically arranged and arc-shaped auxiliary plates 482 are fixedly installed. A maintenance assembly 49 is provided on the fixed disk 34. The maintenance assembly 49 includes a number of hollow rubber boxes 491 fixedly installed on the fixed disk 34. A liquid guide pipe 492 is fixedly installed on one side of the rubber box 491. The end of the liquid guide pipe 492 away from the rubber box 491 communicates with the cleaning plate 45. A reverse "U"-shaped connecting rod 50 is fixedly installed on the surface of the fixed cylinder 43, and the connecting rod 50 passes through the brush 46.

[0034] During operation, when the deburring work on the card strip body 4 is completed, the electric push rod 12 drives the connecting arm 14, the extension arm 15, the cutting knife 17 and other components to move upward and reset through the fixed column 13. When the connecting arm 14 moves upward, it will drive the extrusion plate 481 and the two arc-shaped auxiliary plates 482 to extrude a number of elastic blocks 41, realizing the function of efficiently extruding the elastic blocks 41, and forcing the gas in the number of elastic blocks 41 to enter the corresponding fixed cylinder 43 through the corresponding connecting pipes 47 after being extruded. The gas pushes the sliding cylinder 44 in the fixed cylinder 43, so that the sliding cylinder 44 drives the cleaning plate 45 and the brush 46 to move towards the cutting knife 17. The "V"-shaped cleaning plate 45 and the brush 46 are used in cooperation to clean the residual plate material on the cutting knife 17, thereby ensuring the sharpness of the end of the cutting knife 17.

[0035] After the cleaning is completed, the electric push rod 12 drives the connecting arm 14 to move downward, and then no longer extrudes the elastic blocks 41. At this time, the gas in the fixed cylinder 43 will flow back into the elastic blocks 41 through the connecting pipes 47, and the sliding cylinder 44 will drive the cleaning plate 45 and the brush 46 to follow and reset. The reset brush 46 will continuously contact the reverse "U"-shaped connecting rod 50, and the connecting rod 50 will continuously swing the brush 46, thereby removing the impurities swept out by the brush 46 and facilitating the efficient operation of the brush 46.

[0036] When the cutting knife 17 has been used for a long time, it needs to be maintained. Therefore, when the electric push rod 12 drives the fixed column 13, the sliding column 33 and the fixed disk 34 to move downward to position the card strip body 4, the electric push rod 12 will continuously drive the fixed column 13 to move towards the fixed disk 34. At this time, the bottom of the fixed column 13 will move towards the fixed disk 34, and the bottom of the fixed column 13 is used to extrude a number of rubber boxes 491 on the top of the fixed disk 34, so that the pre-stored maintenance liquid in the rubber boxes 491 is sprayed on the brush 46 through the liquid guide pipe 492. Subsequently, when the brush 46 removes impurities from the cutting knife 17, it will use the maintenance liquid on the surface to perform maintenance operations on the cutting knife 17, thereby extending the service life of the cutting knife 17.

[0037] A blowing-off mechanism 60 is arranged inside the fixed column 13. The blowing-off mechanism 60 includes a communicating pipe 61 that is communicated with the inside of the storage groove 31 and is provided with a one-way valve. One end of the communicating pipe 61 away from the storage groove 31 is communicated with the palletizer 1, and a through groove 62 is formed on one surface of the palletizer 1; the elastic member 32 is a hollow elastic ball, shrinkage holes are formed on the surface of the elastic ball, the sliding column 33 is in sealed sliding connection with the fixed column 13, and a pipe that is communicated with the inside and is provided with a one-way valve is fixedly installed on one surface of the fixed column 13. A hollow clamping plate 63 is clamped on one surface of the palletizer 1, and a plurality of air outlets 64 that are communicated with the inside are formed on one surface of the clamping plate 63 close to the clamping plate strip body 4, and one end of the communicating pipe 61 away from the storage groove 31 is communicated with the inside of the clamping plate 63.

[0038] During operation, when the fixed column 13 slides downward toward the sliding column 33, it will squeeze a plurality of elastic members 32 inside, so that the gas in the elastic members 32 is discharged into the storage groove 31 of the fixed cone through the shrinkage holes, and the gas in the storage groove 31 enters the clamping plate 63 together through the communicating pipe 61, and is blown onto the conveyor belt of the palletizer 1 through the air outlet holes of the clamping plate 63, and the impurities generated after cutting on the conveyor belt are blown out through the through groove 62. After the gas in the elastic member 32 is squeezed out, when it is no longer squeezed by the fixed column 13, it will be supplemented with air through the pipe, so as to facilitate the next use. When all the clamping plate strip bodies 4 on the palletizer 1 are conveyed to the next process, at this time, there is no clamping plate strip body 4 on the palletizer 1. The electric push rod 12 is started again and the above steps are repeated. At this time, due to the lack of obstruction of the clamping plate strip body 4, the gas blown out by the air outlet 64 can comprehensively clean the palletizer 1, so as to reduce the influence of impurities remaining on the palletizer 1 on the flatness of the subsequent stacking of the clamping plate strip bodies 4.

[0039] Working principle: The pallet strip body 4 is conveyed to the palletizer 1 through a conveyor belt. At this time, the two clamping plates 3 and the two positioning plates 6 will move towards the pallet strip body 4 under the action of several cylinders and clamp it. Clamping the four sides of the pallet strip body 4 can increase the stability and prevent the pallet strip body 4 from falling during the ascending and descending processes. At this time, the support 2 will drive the clamping plate 3, the positioning plate 6 and the pallet strip body 4 to move upward under the action of the cylinder, leaving a gap between the pallet strip body 4 and the surface of the palletizer 1, facilitating the next pallet strip body 4 to flow onto the palletizer 1. Then, by loosening the two clamping plates 3 and the two positioning plates 6, the originally clamped pallet strip body 4 falls onto the pallet strip body 4 on the palletizer 1. At this time, the fixed frame 11 drives the clamping plate 3 and the positioning plate 6 to move downward and reset, facilitating the continuous repetition of the above operations, thereby stacking several pallet strip bodies 4 to the required height to complete the palletizing operation. After the palletizing operation is completed, the conveyor belt on the palletizer 1 starts, conveying several pallet strip bodies 4 to the next process for flipping operation, and after the flipping operation is completed, it enters the final film packaging. When several pallet strip bodies 4 complete the palletizing work on the palletizer 1, the palletized pallet strip bodies 4 are waiting for transportation on the conveyor belt. At this time, first use the air pump 18 to convey gas through several air ducts 19 into several connecting arms 14, thereby pushing several extension arms 15 in the several connecting arms 14 to move, so that the extension arms 15 drive the fixed plate 16 and the cutting knife 17 to move to a suitable position, thereby facilitating the adaptation to different sizes of pallet strip bodies 4 and improving the adaptability of the equipment during use. Then start the electric push rod 12 on the fixed frame 11, and the electric push rod 12 drives the fixed column 13, the connecting arm 14, the extension arm 15, the fixed plate 16 and the cutting knife 17 to move towards the pallet strip body 4 together through the output end. Use the end of the cutting knife 17 to cut and remove the burrs around the pallet strip body 4. As the cutting knife 17 contacts the periphery of the pallet strip body 4, the internal grinding plate 21 continuously contacts the pallet strip body 4 for fine grinding and further removes the burrs around the pallet strip body 4.

[0040] When the electric push rod 12 drives the fixed column 13 to move downward, it will drive the sliding column 33 to move downward together through the fixed column 13, so that the fixed disk 34, several rectangular plates 35 and several gaskets 36 at the bottom of the sliding column 33 move downward together, and use the fixed disk 34, the rectangular plates 35 and the gaskets 36 to press and position the palletized pallet strip body 4, so that the pallet strip body 4 will not displace during subsequent cutting.

[0041] After the deburring work on the pallet strip body 4 is completed, the electric push rod 12 drives components such as the connecting arm 14, the extension arm 15, and the cutting knife 17 to move upward and reset through the fixed column 13. When the connecting arm 14 moves upward, it will drive the pressing plate 481 and two arc-shaped auxiliary plates 482 to press several elastic blocks 41, achieving the effect of efficiently pressing the elastic blocks 41, and forcing the gas in several elastic blocks 41 to enter the corresponding fixed cylinder 43 through the corresponding connecting pipes 47 after being pressed. The gas pushes the sliding cylinder 44 in the fixed cylinder 43, causing the sliding cylinder 44 to drive the cleaning plate 45 and the brush 46 to move towards the cutting knife 17. After the cleaning is completed, the electric push rod 12 drives the connecting arm 14 to move downward, and thus no longer presses the elastic blocks 41. At this time, the gas in the fixed cylinder 43 will flow back into the elastic blocks 41 through the connecting pipes 47, and the sliding cylinder 44 will drive the cleaning plate 45 and the brush 46 to follow and reset. The reset brush 46 will continuously contact the inverted "U"-shaped connecting rod 50, and use the connecting rod 50 to continuously swing the brush 46, so as to remove the impurities swept out by the brush 46, facilitating the efficient operation of the brush 46. When the cutting knife 17 needs to be maintained after long-term use. Therefore, when the electric push rod 12 drives the fixed column 13, the sliding column 33, and the fixed disk 34 to move downward to position the pallet strip body 4, the electric push rod 12 will continuously drive the fixed column 13 to move towards the fixed disk 34. At this time, the bottom of the fixed column 13 will move towards the fixed disk 34, and use the bottom of the fixed column 13 to press several rubber boxes 491 on the top of the fixed disk 34, so that the pre-stored maintenance liquid in the rubber boxes 491 is sprayed on the brush 46 through the liquid guide pipe 492.

[0042] When the fixed column 13 slides downward towards the sliding column 33, it will press several elastic members 32 inside, causing the gas in the elastic members 32 to be discharged into the receiving groove 31 of the fixed cone through the shrinkage holes, and discharging the gas in the receiving groove 31 into the clamping plate 63 through the communication pipe 61 together, and blowing the gas through the air outlet holes of the clamping plate 63 onto the conveyor belt of the palletizer 1, and blowing out the impurities generated after cutting on the conveyor belt through the through groove 62. After the gas in the elastic members 32 is squeezed out, when it is no longer pressed by the fixed column 13, it will be refilled with gas through the pipeline, facilitating the next use. When all the pallet strip bodies 4 on the palletizer 1 are conveyed to the next process, at this time, there is no pallet strip body 4 on the palletizer 1. Start the electric push rod 12 again and repeat the above steps. At this time, due to the lack of obstruction of the pallet strip body 4, the gas blown out from the air outlet 64 can comprehensively clean the palletizer 1.
