[0001] The present invention relates to the technical field of bamboo product production, and particularly relates to a corner cutting device for bamboo product production. Background Art

[0002] Bamboo products refer to products made from bamboo as the processing raw material, mostly daily necessities, such as bamboo baskets, bamboo sieves, bamboo strainers, rice sieves, bamboo steamers, cooking brooms, bamboo dustpans, bamboo dustpans, bamboo rakes, baskets, bamboo shoulder poles, bamboo chopsticks, bamboo brooms, bamboo hats, bamboo plaques, bamboo back baskets, bamboo mats, bamboo mats, bamboo beds, bamboo stools, bamboo chairs, bamboo reclining chairs, chopping boards, cooling mats, tea cup pads, curtains, etc. In recent years, relatively popular bamboo floors and bamboo furniture, etc., and there are also some with higher value, such as bamboo carvings and other folk handicrafts, and bamboo charcoal products also have good prospects.

[0003] During the processing of bamboo products, it is necessary to cut the corners of bamboo tubes to meet the processing requirements of bamboo products. When the existing cutting equipment cuts bamboo tubes, manual feeding and discharging are often used, which has the defects of poor continuity and low processing efficiency.

[0004] Based on this, it is necessary to design a corner cutting device for bamboo product production with automatic feeding and discharging functions. Summary of the Invention

[0005] The technical solution of the present invention is: a corner cutting device for bamboo product production, including a bottom frame, an inclined frame and a cutting frame.

It is characterized in that: it further includes a guide rod three, a U-shaped frame, a lifting frame, an n-shaped frame, an electric slide rail, a slider, a cylindrical push block, a 7-shaped rod, a clamping assembly, a support assembly and a cutting assembly. A clamping assembly for clamping the bamboo tube to be cut for easy feeding is arranged between the inclined frame and the cutting frame. Guide rod threes are symmetrically arranged on both sides of the top of the bottom frame. A U-shaped frame is slidably arranged on the guide rod threes together. The two ends of the U-shaped frame are jointly connected to a lifting frame. An electric slide rail is installed on the cutting frame. A slider is slidably connected to the electric slide rail. A cylindrical push block is connected to the side of the slider facing the guide rod three. A 7-shaped rod is connected to the top of the slider. The 7-shaped rod is slidably matched with the inner wall of the lifting frame. The end of the 7-shaped rod away from the slider passes through the lifting frame and is slidably connected to the n-shaped frame installed on the cutting frame. The n-shaped frame is arranged between the guide rod three and the electric slide rail. A support assembly for supporting the bamboo tube for the cutting assembly to cut it is slidably arranged on the cutting frame. The electric slide rail drives the cylindrical push block through the slider to push the cut bamboo tube away from the cutting frame to realize automatic discharging of the bamboo tube. The horizontal movement of the 7-shaped rod drives the lifting of the lifting frame and the U-shaped frame to feed the bamboo tube on the clamping assembly to the support assembly above the cutting frame.

[0006] As a preferred technical solution of the present invention, the clamping assembly includes a lifting block and a clamping block. Symmetrical lifting blocks are connected to one side of the U-shaped frame close to the inclined frame, and a clamping block for clamping and feeding bamboo tubes is rotatably connected to one side of the lifting block facing the bottom frame.

[0007] As a preferred technical solution of the present invention, it further includes a gear and a rack. A gear is rotatably arranged on the side of the lifting block facing away from the clamping block. The gear is coaxially connected to the clamping block. A rack meshing with the gear is arranged on the side wall of the bottom frame. The number of teeth on the rack is 1 / 4 of the number of teeth of the gear. After the gear meshes with the rack, the lifting operation of the lifting block drives the clamping block to rotate 90 degrees.

[0008] As a preferred technical solution of the present invention, the support assembly includes a bidirectional lead screw one, a guide rod four and a support block. The bidirectional lead screw one and the guide rod four are arranged in parallel on the cutting frame. The two ends of the bidirectional lead screw one and the guide rod four are jointly movably connected to the support block, and the support block is slidably connected to the cutting frame.

[0009] As a preferred technical solution of the present invention, the cutting assembly includes a bidirectional lead screw two, a guide rod five and a cutting saw. The bidirectional lead screw two and the guide rod five are arranged in parallel on the U-shaped frame. The two ends of the bidirectional lead screw two and the guide rod five are jointly movably connected to the cutting saw, and the cutting assembly is arranged above the support assembly.

[0010] As a preferred technical solution of the present invention, it further includes an L-shaped frame, a connecting block, a guide rod one, a spring one, a guide rod two and a spring two. A connecting block is arranged between the inclined frame and the cutting frame. A guide rod one is arranged in the inner cavity of the connecting block. An L-shaped frame is slidably connected to the guide rod one. The L-shaped frame is arranged below the lifting block and is in contact and cooperation with the lifting block. A spring one is arranged between the bottom of the L-shaped frame and the inner wall of the bottom of the connecting block. The spring one is wound around the guide rod one. One end of the L-shaped frame away from the guide rod one is slidably connected to the guide rod two arranged on the cutting frame. A spring two is wound around the guide rod two, and the two ends of the spring two are respectively connected to the L-shaped frame and the cutting frame.

[0011] As a preferred technical solution of the present invention, it further includes mounting blocks, guide rods VI, springs III, pressing blocks, L-shaped frames, T-shaped frames, V-shaped frames, elastic abrasive papers and wedge blocks. Mounting blocks are symmetrically installed on the side walls of the protruding parts of the cutting frame away from the lifting frame. The cylindrical pushing block pushes the bamboo tube to pass through the gap between the two mounting blocks. Guide rods VI are installed in the inner cavities of the mutually approaching sides of the two mounting blocks. A pressing block is slidably connected to the top of the guide rod VI. The pressing block is in extrusion fit with the bamboo tube pushed by the cylindrical pushing block. The side of the pressing block facing the cylindrical pushing block is provided with an inclined surface. A spring III is arranged between the bottom of the pressing block and the inner wall of the mounting block. The spring III is wound around the guide rod VI. An L-shaped frame is slidably arranged in the inner cavity of the mounting block. The two ends of the L-shaped frame are commonly connected to a V-shaped frame. An elastic abrasive paper is wound around the V-shaped frame. One end of the L-shaped frame close to the guide rod VI is connected to a wedge block that is slidably matched with the inclined groove opened at the bottom of the pressing block. A T-shaped frame that slidably passes through the mounting block is arranged on the side wall of the L-shaped frame.

[0012] As a preferred technical solution of the present invention, it further includes a turntable, equally spaced cutting knives and an annular knife rest. The cutting frame is rotatably connected with a turntable on the side provided with the mounting block. Circular holes for the bamboo tube to pass through are evenly spaced on the circumferential wall of the turntable. Equally spaced cutting knives for equally spacing and cutting the bamboo tube are installed in the circular holes. An annular knife rest for removing the bamboo joints inside the bamboo tube is rotatably arranged on the side of the equally spaced cutting knife close to the cutting frame.

[0013] Beneficial effects: 1. The slider moves horizontally along the electric slide rail, and drives the lifting frame to perform lifting motion through the 7-shaped rod. When the U-shaped frame moves upward along the guide rod III under the drive of the lifting frame, the U-shaped frame drives the lifting block and the clamping block to move upward, so as to lift the bamboo tube on the clamping block upward. After the U-shaped frame rises, the gear meshes with the rack. As the U-shaped frame continues to rise, under the cooperation of the gear and the rack, the clamping block rotates clockwise by 90 degrees, so as to load the bamboo tube onto the support block, providing convenience for cutting and realizing the feeding function of the bamboo tube; when the slider moves along the electric slide rail, the cylindrical pushing block pushes the bamboo tube on the support block in the direction away from the cutting frame, so as to achieve the effect of automatically unloading the bamboo tube that has completed the cutting operation.

[0014] 2. The bamboo tube squeezes the pressing block, and the downward movement of the pressing block drives the wedge blocks on both sides to approach each other, thereby driving the L-shaped frames to approach each other, causing the elastic abrasive paper to deform and closely adhere to the outer wall of the bamboo tube, so as to polish the outer wall of the bamboo tube.

[0015] 3. When the bamboo tube passes through the circular hole on the turntable, the annular knife rest scrapes off the bamboo joints inside the bamboo tube, and the equally spaced cutting knives cut the bamboo tube into bamboo slices. Description of the Drawings

Specific Embodiments

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0029] Embodiment: A corner cutting device for bamboo product production, as shown in Figure 1 , Figure 3 and Figure 4 , includes a chassis 1, an inclined frame 2, a cutting frame 3, a third guide rod 4, a U-shaped frame 5, a lifting frame 51, an n-shaped frame 6, an electric slide rail 7, a slider 8, a cylindrical pushing block 9, a 7-shaped rod 10, a clamping assembly, a support assembly, and a cutting assembly. The inclined frame 2 and the cutting frame 3 are arranged side by side on the top of the chassis 1. The inclined surface of the inclined frame 2 faces the direction of the cutting frame 3. The inclined frame 2 is used for the rolling feeding of the bamboo tube 100. A debris collection box is slidably arranged on the cutting frame 3. A clamping assembly for clamping the bamboo tube 100 to be cut for feeding is arranged between the inclined frame 2 and the cutting frame 3. The third guide rods 4 are arranged on both the front and rear sides of the top of the chassis 1. The third guide rods 4 are arranged between the inclined frame 2 and the cutting frame 3. A U-shaped frame 5 is slidably arranged on the third guide rods 4 on both sides. The U-shaped frame 5 is located above the cutting frame 3. The two ends of the right side of the U-shaped frame 5 are commonly connected with a lifting frame 51. The front side of the lifting frame 51 is provided with a convex inverted V shape. An electric slide rail 7 is installed on the cutting frame 3. A slider 8 is slidably connected to the electric slide rail 7. The left side of the slider 8 is connected with a cylindrical pushing block 9. The top of the slider 8 is connected with a 7-shaped rod 10. The 7-shaped rod 10 is slidably matched with the inner wall of the lifting frame 51. The end of the 7-shaped rod 10 far from the slider 8 passes through the lifting frame 51 and is slidably connected with an n-shaped frame 6 installed on the cutting frame. The n-shaped frame 6 is arranged between the third guide rod 4 and the electric slide rail 7. When the slider 8 moves horizontally along the electric slide rail 7, the 7-shaped rod 1 moves along the inner wall track of the lifting frame 51, thereby driving the lifting frame 51 and the U-shaped frame 5 to perform lifting movements. A support assembly for supporting the bamboo tube 100 to facilitate the cutting by the cutting assembly is slidably arranged on the cutting frame 3. The electric slide rail 7 drives the cylindrical pushing block 9 through the slider 8 to push the cut bamboo tube 100 away from the cutting frame 3 to realize the automatic unloading of the bamboo tube 100. The horizontal movement of the 7-shaped rod 10 drives the lifting of the lifting frame 51 and the U-shaped frame 5 to feed the bamboo tube 100 on the clamping assembly to the support assembly above the cutting frame 3.

[0030] As shown in Figure 3 and Figure 5 , the clamping assembly includes a lifting block 11 and a clamping block 12. Symmetrical lifting blocks 11 are connected to the side of the U-shaped frame 5 close to the inclined frame 2. The side of the lifting block 11 facing the chassis 1 is rotatably connected with a clamping block 12 for clamping and feeding the bamboo tube 100.

[0031] As shown in Figure 3As shown in the figure, it further includes a gear 13 and a rack 14. A gear 13 is rotatably arranged on one side of the lifting block 11 facing away from the clamping block 12. The gear 13 is coaxially connected to the clamping block 12. A rack 14 meshing with the gear 13 is arranged on the side wall of the chassis 1. The lifting block 11 can only mesh with the rack 14 after rising. The number of teeth on the rack 14 is 1 / 4 of the number of teeth of the gear 13. After the gear 13 meshes with the rack 14, the lifting and lowering operation of the lifting block 11 can realize the function of rotating the clamping block 12 by 90 degrees through the cooperation of the rack 14 and the gear 13, so as to load the bamboo tube 100 on the clamping block 12 onto the support assembly.

[0032] As Figure 7 shown in the figure, the support assembly includes a bidirectional lead screw 15, a guide rod 16 and a support block 17. The bidirectional lead screw 15 and the guide rod 16 are arranged in parallel on the cutting frame 3. The bidirectional lead screw 15 is rotatably connected to the cutting frame 3. Both ends of the bidirectional lead screw 15 and the guide rod 16 are jointly movably connected to a support block 17. The support block 17 is threadedly connected to the bidirectional lead screw 15. The guide rod 16 is slidably connected to the support block 17. The support block 17 is slidably connected to the left side of the cutting frame 3. A chute for the support block 17 to slide is provided on the left side of the cutting frame 3. The support block 17 is in an inclined shape with the left side higher than the right side and the top of the right side is set as an arc-shaped hook. This design is conducive to limiting the bamboo tube 100 and facilitating the cutting of the cutting assembly. By rotating the bidirectional lead screw 15, the distance between the support blocks 17 is adjusted, so as to adjust the position of the support blocks 17 according to the length of the bamboo tube. When the cylindrical push block 9 pushes the bamboo tube 100 to move, the cylindrical push block 9 slides in cooperation with the top of the support block 17.

[0033] As Figure 8 shown in the figure, the cutting assembly includes a bidirectional lead screw 19, a guide rod 20 and a cutting saw 21. The bidirectional lead screw 19 and the guide rod 20 are arranged in parallel on the U-shaped frame 5. The bidirectional lead screw 19 is rotatably connected to the U-shaped frame 5. Both ends of the bidirectional lead screw 19 and the guide rod 20 are jointly movably connected to a cutting saw 21. The cutting saw 21 is threadedly connected to the bidirectional lead screw 19. The cutting saw 21 is slidably connected to the guide rod 20. By adjusting the bidirectional lead screw 19, the distance between the cutting saws 21 on the front and rear sides is adjusted, so as to flexibly adjust the positions of the two cutting saws 21 according to the needs of the cutting length. The cutting assembly is arranged above the support assembly.

[0034] As Figure 6As shown, it further includes an L-shaped frame 18, a connecting block 101, a first guiding rod 102, a first spring 103, a second guiding rod 301 and a second spring 302. A connecting block 101 is provided between the inclined frame 2 and the cutting frame 3. A first guiding rod 102 is arranged inside the cavity of the connecting block 101. An L-shaped frame 18 is slidably connected to the first guiding rod 102. The L-shaped frame 18 is arranged below the lifting block 11 and is in contact and cooperation with the lifting block 11. A first spring 103 is provided between the bottom of the L-shaped frame 18 and the inner wall of the bottom of the connecting block 101. The first spring 103 is wound around the first guiding rod 102. The other end of the L-shaped frame 18 is slidably connected to a second guiding rod 301 arranged on the cutting frame 3. A second spring 302 is wound around the second guiding rod 301. Both ends of the second spring 302 are connected to the L-shaped frame 18 and the cutting frame 3 respectively. Figure 6 The first spring 103 and the second spring 302 shown are both in a compressed and deformed state. When the lifting block 11 moves downward along with the U-shaped frame 5, the L-shaped frame 18 moves downward along the first guiding rod 102 and the second guiding rod 301, and compresses the first spring 103 and the second spring 302. The left side of the L-shaped frame 18 extends into the cavity of the connecting block 101 (as shown in Figure 6 ). At this time, the bamboo tube 100 on the inclined frame 2 can automatically roll down between the front and rear clamping blocks 12 under the action of gravity; when the lifting block 11 moves upward along with the U-shaped frame 5, the first spring 103 and the second spring 302 reset, and the L-shaped frame 18 moves upward. The left end of the L-shaped frame 18 protrudes from the top of the connecting block 101. At this time, the L-shaped frame 18 blocks the bamboo tube 100 on the inclined frame 2. Repeating this way, the function of feeding the bamboo tubes 100 on the inclined frame 2 onto the clamping blocks 12 one by one is realized.

[0035] During use, the bamboo tube 100 that needs to be cut at the corners is placed on the inclined frame 2. In the initial state, this device is as shown in Figure 1 . The slider 8 is located at the front end of the electric slide rail 7, the 7-shaped rod 10 is located at the top of the inner wall of the inverted V shape on the front side of the lifting frame 51, the U-shaped frame 5, the lifting frame 51, and the lifting block 11 are all at the lowest points. At this time, the lifting block 11 generates a downward extrusion force on the L-shaped frame 18. The L-shaped frame 18 compresses the first spring 103 and the second spring 302. The left end of the L-shaped frame 18 extends into the cavity of the connecting block 101 (as shown in Figure 6In the state shown, at this time, the bamboo tube 100 on the inclined frame 2 can roll between the arc-shaped placement blocks 111 on the front and back sides. Subsequently, the slider 8 moves from front to back along the electric slide rail 7, and the 7-shaped rod 10 moves horizontally along the n-shaped frame 6. Since the inner wall of the lifting frame 51 is in contact and cooperation with the upper part of the 7-shaped rod 10, the lifting frame 51 is thus pushed upward, thereby lifting the U-shaped frame 5 upward. The U-shaped frame 5 drives the lifting block 11 to move upward, thereby gradually lifting the bamboo tube 100 upward; as the U-shaped frame 5 moves upward, the gear 13 meshes with the rack 14. As the U-shaped frame 5 continues to move upward, under the cooperative action of the rack 14, the gear 13 drives the clamping block 12 to rotate clockwise by 90 degrees, thereby pushing the bamboo tube 100 on the clamping block 12 onto the support block 17, thus realizing the function of feeding the bamboo tube 100; subsequently, the slider 8 moves from back to front along the electric slide rail 7, and the 7-shaped rod 10 moves horizontally forward. When the 7-shaped rod 10 moves to the inner wall of the inverted V shape on the front side of the lifting frame 51, the lifting frame 51 starts to move downward, thereby driving the U-shaped frame 5 and the cutting saw 21 to move downward, and the cutting saw 21 then performs cutting operations on both ends of the bamboo tube 100, thereby realizing the function of cutting the bamboo tube according to the needs of bamboo product processing; after the cutting operation is completed, the slider 8 moves from front to back along the electric slide rail 7, and the cylindrical push block 9 then pushes the bamboo tube 100 that has completed the cutting operation backward, thus realizing the discharging function of the bamboo tube 100; when the U-shaped frame 5 drives the lifting block 11 to move downward, the lifting block 11 generates a downward pressing force on the L-shaped frame 18. The L-shaped frame 18 compresses the first spring 103 and the second spring 302 and moves downward along the first guide rod 102 and the second guide rod 301. After the L-shaped frame 18 moves downward into the connecting block 101, the bamboo tube 100 on the inclined frame 2 then rolls onto the clamping block 12, thus feeding the bamboo tube 100 from the inclined frame 2 to the clamping block 12. Through the above reciprocating operations, the automatic feeding and discharging of the bamboo tube 100 can be realized.

[0036] As Figure 2 , Figure 9 and Figure 10 shown, it further includes a mounting block 22, a sixth guide rod 221, a third spring 222, a pressing block 23, an L-shaped frame 24, a T-shaped frame 241, a V-shaped frame 25, an elastic abrasive paper 26, and a wedge-shaped block 27. Mounting blocks 22 are symmetrically installed on the side wall of the protruding part of the cutting frame 3 away from the lifting frame 51. The cylindrical push block 9 pushes the bamboo tube 100 to pass through the gap between the two mounting blocks 22. Sixth guide rods 221 are installed in the inner cavities of the mutually approaching sides of the two mounting blocks 22. A pressing block 23 is slidably connected to the top of the sixth guide rod 221. The pressing block 23 is in extrusion cooperation with the bamboo tube 100 pushed by the cylindrical push block 9. The side of the pressing block 23 facing the cylindrical push block 9 is provided with an inclined surface. In the initial state, the pressing block 23 is directly opposite to the cylindrical push block 9. A third spring 222 is arranged between the bottom of the pressing block 23 and the inner wall of the mounting block 22. The third spring 222 is wound around the sixth guide rod 221. The initial state of the third spring 222 is as Figure 11As shown, a sliding L-shaped frame 24 is arranged inside the installation block 22. Both ends of the L-shaped frame 24 are jointly connected with a V-shaped frame 25. An elastic abrasive sandpaper 26 is wound around the V-shaped frame 25. The V-shaped frame 25 and the elastic abrasive sandpaper 26 form a triangular structure. One end of the L-shaped frame 24 near the guide rod six 221 is connected with a wedge-shaped block 27 that is slidably matched with an inclined groove 231 opened at the bottom of the lower pressing block 23. A T-shaped frame 241 is arranged on the side wall of the L-shaped frame 24 and slidably penetrates through the installation block 22. A guide groove for the T-shaped frame 241 to slide is opened on the installation block 22.

[0037] As Figure 2 and Figure 11 As shown, it further includes a turntable 28, an equally divided cutting knife 29 and an annular knife rest 30. One side of the cutting frame 3 where the installation block 22 is arranged is rotatably connected with a turntable 28. Circular holes for the bamboo tube 100 to pass through are evenly spaced on the circumferential wall of the turntable 28. An equally divided cutting knife 29 for equally spacing and cutting the bamboo tube 100 is installed in the circular hole. An annular knife rest 30 for scraping the bamboo joints inside the bamboo tube 100 is rotatably arranged on one side of the equally divided cutting knife 29 near the cutting frame 3.

[0038] When the cylindrical push block 9 pushes the bamboo tube 100 to unload from front to back, the bamboo tube 100 gradually approaches the inclined surface side of the lower pressing block 23. As the bamboo tube 100 squeezes the inclined surface side of the lower pressing block 23, the lower pressing block 23 moves downward along the guide rod six 221 and compresses the spring three 222; when the lower pressing block 23 moves downward, the wedge-shaped block 27 moves relative to the inclined groove 231, thereby driving the L-shaped frames 24 on both left and right sides to approach the lower pressing block 23. The elastic abrasive sandpaper 26 between the upper and lower end points of the V-shaped frame 25 tightly adheres to the bamboo tube 100 and deforms, so as to polish the outer wall of the bamboo tube 100 through the elastic abrasive sandpaper 26; switch to the equally divided cutting knife 29 of the required specification through the turntable 28. As the bamboo tube 100 moves further backward, the bamboo tube 100 passes through the circular hole on the turntable 28. The annular knife rest 30 scrapes the bamboo joints inside the bamboo tube 100, and the equally divided cutting knife 29 equally spaces and cuts the bamboo tube 100 that has completed the polishing operation, so as to obtain bamboo slices of the required specification, which provides convenience for the production of bamboo and wooden products.
