Description

Technical Field

[0001] This utility model relates to the field of bamboo product processing technology, specifically to a bamboo splitting device. Background Technology

[0002] Bamboo products refer to products made from bamboo as raw material, and their applications are increasingly common in daily life and production. When processing bamboo into products needed in our daily lives, the entire bamboo stalk needs to be split into strips of appropriate width before further processing. Existing bamboo splitting machines require manual placement of the bamboo between a pushing mechanism and a cutting disc mechanism. The pushing mechanism then drives the bamboo to move, splitting it into strips. During this process, the operator must hold the bamboo and align it with the cutting disc mechanism until both ends are firmly clamped by the pushing and cutting disc mechanisms. This is physically demanding for workers, and prolonged support can easily lead to hand fatigue and the risk of hand injury.

[0003] Chinese Patent Publication No. CN217833998U discloses an automatic bamboo splitting machine, including a main body. A sliding frame is slidably mounted on the surface of the main body, and a blade holder is fixedly mounted on the surface of the main body. Two bases are fixedly mounted on the lower surface of the main body, and a motor is fixedly mounted on the surface of one of the bases. A support device is provided on the side wall of the blade holder. The support device includes two rectangular bars, both of which are fixedly connected to the two sides of the blade holder. A limiting groove is provided on the surface of the rectangular bars, and a sliding block is slidably connected to the inner wall of the limiting groove. A support block is fixedly connected to the surface of the sliding block, and a connecting block is fixedly connected to the surface of the sliding block. A bolt rod is threaded into the connecting block. Although this patent can use the support block to support one end of the bamboo, so that the end face of the bamboo near the blade holder is as close as possible to the center of the blade holder, which can reduce the fatigue of the operator's hands to a certain extent, it is still necessary to manually hold the other end of the bamboo until the sliding frame touches the other end of the bamboo before releasing the hand, which poses a risk of being pinched. Utility Model Content

[0004] The main purpose of this utility model is to overcome the defects of the above-mentioned background technology and provide a bamboo splitting device.

[0005] To achieve the above objectives, the present invention proposes a bamboo splitting device, comprising a frame, a clamping assembly, a pushing assembly, a cutter head assembly, and a power assembly. The pushing assembly is movably mounted on the frame, and the power assembly is mounted on the frame and connected to the pushing assembly. The cutter head assembly is located at one end of the frame and corresponds to the end of the pushing assembly in the pushing direction. The clamping assembly is located in the middle of the frame and includes a pushing member, a top rod, and a clamping rod. Guide sleeves inclined towards the middle of the frame are symmetrically provided on both sides of the frame. The clamping rods are slidably mounted on the guide sleeves. The bottom end of the clamping rod is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to the middle of the top rod. The bottom end of the top rod is connected to the extended end of the pushing member. The pusher drives the top rod to rise and fall, and the top rod simultaneously drives the clamping rods on both sides to rise and fall. As the clamping rods rise, the tops of the clamping rods gradually move closer together and clamp the two sides of the bamboo, automatically centering and positioning the bamboo. This eliminates the need for manual support of the bamboo for centering, reducing labor intensity and improving the safety of the bamboo splitting device.

[0006] To further optimize the technical solution, two sets of clamping components are provided at intervals. A crossbar is fixed to the bottom end of the top rod in each set of clamping components, and the protruding end of the pushing member is fixed to the middle of the crossbar. By setting two sets of clamping components to simultaneously center and clamp the bamboo, the centering clamping is more stable, and a single pushing member can simultaneously drive both sets of clamping components to work.

[0007] To further optimize the technical solution, the pushing component can be any one of a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0008] To further optimize the technical solution, the clamping rod is provided with a clamping section, a sliding section and a connecting section. The sliding section is slidably disposed within the guide sleeve. The clamping section is horizontally disposed at the top end of the sliding section. The connecting section is disposed at the bottom end of the sliding section. One end of the connecting rod is hinged to the connecting section.

[0009] To further optimize the technical solution, a V-shaped groove is provided at the end of the clamping section, and a V-shaped support plate is provided at the top of the top rod. By setting the clamping part into a V-shaped structure, stable positioning can be provided when clamping bamboo, ensuring that the bamboo will not shift during the clamping process, and it can adapt to bamboo of different diameters, effectively improving clamping efficiency.

[0010] To further optimize the technical solution, several rollers are rotatably mounted within both the V-shaped support plate and the V-shaped groove. The rotatable direction of the rollers is consistent with the pushing direction of the pushing assembly. These rollers ensure that the bamboo can still move axially after being clamped.

[0011] To further optimize the technical solution, a guide block is provided at the top of the clamping section. The guide block facilitates the guidance of the bamboo onto the V-shaped support plate.

[0012] The technical solution is further optimized. The blade assembly includes a blade holder and a bamboo splitting blade. The blade holder is fixedly mounted on one end of the frame, and the bamboo splitting blade is detachably inserted into the blade holder. The blade holder has a through hole corresponding to the bamboo splitting blade.

[0013] To further optimize the technical solution, the pushing component includes a mobile platform with rotatable rollers around its perimeter. The frame has corresponding grooves for the rollers. The bottom of the mobile platform is connected to the power component. A stop block is vertically provided on the top surface of the mobile platform, and a push block in the shape of a trumpet is horizontally provided on the stop block.

[0014] To further optimize the technical solution, the power assembly includes a drive motor, a gearbox, a transmission chain, and a control cabinet. The output end of the drive motor is connected to the input end of the gearbox, the output end of the gearbox is connected to the transmission chain, the transmission chain is connected to the bottom of the mobile platform, the control cabinet is located at the bottom of the frame, and the control cabinet contains a control circuit, which is electrically connected to the drive motor.

[0015] The beneficial effects of this utility model include: the pusher drives the top rod to rise and fall, and the top rod synchronously drives the clamping rods on both sides to rise and fall. Since the clamping rods on both sides are inclined towards each other, the top of the clamping rods gradually approaches each other during the rising process, so that the clamping rods on both sides can clamp the two sides of the bamboo. Together with the top of the top rod supporting the bottom of the bamboo, the bamboo is automatically centered and positioned. Then, the pushing component pushes the bamboo to the center of the cutter head assembly for cutting. There is no need for manual hand support to center the bamboo, which reduces labor intensity and improves the safety of the bamboo splitting device. Attached Figure Description

[0027] Please see Figures 1 to 6The bamboo splitting device disclosed in one embodiment includes a frame 1, a clamping assembly 2, a pushing assembly 3, a cutter head assembly 4, and a power assembly 5. The pushing assembly 3 is movably mounted on the frame 1. The power assembly 5 is mounted on the frame 1 and connected to the pushing assembly 3, used to drive the pushing assembly 3 to move on the frame 1. The cutter head assembly 4 is located at one end of the frame 1 and corresponds to the end of the pushing assembly 3 in the pushing direction. The clamping assembly 2 is located in the middle of the frame 1. Specifically, the pushing assembly 3 can move left and right on the frame 1 to split the bamboo. Bamboo 6 is pushed towards the cutter head assembly 4 to split the bamboo. The clamping assembly 2 is used to clamp the bamboo 6 so that both ends of the bamboo 6 are aligned with the cutter head assembly 4 and the pusher assembly 3, respectively. The clamping assembly 2 includes a pusher 201, a push rod 202, and a clamping rod 203. Guide sleeves 204 inclined towards the middle of the frame 1 are symmetrically provided on both sides of the frame 1. The guide sleeves 204 are fixed on both sides of the frame 1. The clamping rods 203 are slidably disposed in the guide sleeves 204. The bottom end of the clamping rod 203 is hinged to one end of the connecting rod 205, and the other end of the connecting rod 205 is connected to the push rod 202. The top rod 202 is hinged in the middle, and its bottom end is connected to the extended end of the pusher 201. Specifically, the guide sleeve 204 is inclined at a 35-45° angle to the horizontal plane, and the intersection of the extended lines of the two sides is located on the axis of symmetry of the frame 1. In this embodiment, the pusher 201 drives the top rod 202 to rise and fall, and the top rod 202 simultaneously drives the clamping rods 203 on both sides to rise and fall. Since the clamping rods 203 on both sides are inclined towards each other, the top ends of the clamping rods 203 gradually approach each other during the rising process, so that the clamping rods 203 on both sides can clamp the two bamboos 6. On the side, the top of the top rod 202 supports the bottom of the bamboo 6, so that the center of the bamboo 6 to be split is aligned with the center of the clamping component 2, the center of the cutter head component 4, and the center of the pushing component 3. Then, the pushing component 3 pushes the bamboo 6 towards the center of the cutter head component 4 for cutting, making the bamboo cut more evenly. The entire bamboo splitting process does not require manual support of the bamboo 6 for centering and support. The bamboo 6 can simply be placed on the top of the top rod 202, which reduces labor intensity and improves the safety of the bamboo splitting device.

[0028] In a preferred embodiment, two sets of clamping components 2 are spaced apart. The bottom ends of the top rods 202 in the two sets of clamping components 2 are fixed with crossbars 206, that is, the two ends of the crossbars 206 are respectively fixedly connected to the bottom ends of the two top rods 202. The protruding end of the pusher 201 is fixed on the middle part of the crossbar 206. Specifically, the pusher 201 is any one of a cylinder, a hydraulic cylinder, or an electric push rod, preferably a cylinder as the power source for clamping. By spaced apart, the two sets of clamping components 2 clamp and center the bamboo 6 to be split, making the clamping more stable. Moreover, the top rods 202 of the two sets of clamping components 2 are connected by the crossbars 206, and the pusher 201 can be used to simultaneously drive the two sets of clamping components 2 to work synchronously to clamp and center the bamboo 6.

[0029] In a specific example, the clamping rod 203 has a clamping section 2031, a sliding section 2032, and a connecting section 2033. The sliding section 2032 is slidably disposed within the guide sleeve 204, the clamping section 2031 is horizontally disposed at the top of the sliding section 2032, and the connecting section 2033 is disposed at the bottom of the sliding section 2032. One end of the connecting rod 205 is hinged to the connecting section 2033. When the top rod 202 is raised and lowered by the pusher 201, the connecting rod 205 can move the entire clamping rod 203 up and down along the guide sleeve 204 by pulling the connecting section 2033 up or down, and effectively clamp and center the side of the bamboo 6 through the end of the clamping section 2031.

[0030] In a preferred embodiment, a V-shaped groove 2034 is provided at the end of the clamping section 2031, with the openings of the V-shaped grooves 2034 on both sides of the clamping section 2031 facing each other, and a V-shaped support plate 2035 is provided at the top of the top rod 202. By setting the clamping part into a V-shaped structure, stable positioning can be provided when clamping the bamboo 6, ensuring that the bamboo 6 will not shift during the clamping process, and it can adapt to bamboo 6 of different diameters, thereby improving clamping efficiency.

[0031] In a preferred embodiment, several rollers 2036 are rotatably provided within both the V-shaped support plate 2035 and the V-shaped groove 2034. The rotatable direction of the rollers 2036 is consistent with the pushing direction of the pushing assembly 3. After the bamboo 6 is clamped on the clamping assembly 2, the outer wall of the bamboo 6 abuts against the rollers 2036, facilitating the pushing assembly 3 to push the bamboo 6 axially. Once both ends of the bamboo 6 abut against the cutter head assembly 4 and the pushing assembly 3 respectively, the clamping assembly 2 can be released to prevent it from obstructing the movement path of the pushing assembly 3. Then, the pushing assembly 3 continues to push the bamboo 6 towards the cutter head assembly 4 for splitting.

[0032] In a preferred embodiment, a guide block 2037 is provided at the top of the clamping section 2031. The guide block 2037 is an inclined block that slopes downward toward the V-groove 2034, so that the bamboo 6 can roll between the two clamping rods 203.

[0033] In a specific example, the blade assembly 4 includes a blade holder 401 and a bamboo splitting blade 402. The blade holder 401 is fixedly mounted on one end of the frame 1, and the bamboo splitting blade 402 is detachably inserted into the blade holder 401. A through hole 403 corresponding to the bamboo splitting blade 402 is provided on the blade holder 401. The split bamboo strips pass through the through hole 403. The bamboo splitting blade 402 can be replaced according to the required width of the bamboo strips. When replacing, the bamboo splitting blade 402 can be pulled up and lifted, which is convenient and quick.

[0034] In a specific example, the pushing component 3 includes a moving platform 301. Rollers 302 are rotatably provided around the moving platform 301. A groove 101 corresponding to the rollers 302 is provided on the frame 1. The rollers 302 are rotatably provided in the groove 101. The sliding connection between the moving platform 301 and the frame 1 is replaced with a rolling connection with less friction, making the moving platform 301 move more smoothly on the frame 1. The bottom of the moving platform 301 is connected to the power component 5 to drive the moving platform 301 to move. A stop block 303 is vertically provided on the top surface of the moving platform 301. A push block 304 in the shape of a flared mouth is horizontally provided on the stop block 303. The center of the flared mouth of the push block 304 is on the same line as the center of the bamboo splitting knife 402. By making the push block 304 in the shape of a flared mouth, when the push block 304 abuts against one end of the bamboo 6 and pushes towards the bamboo splitting knife 402, the bamboo 6 is less likely to deviate on the push block 304.

[0035] In a specific example, the power assembly 5 includes a drive motor 501, a gearbox 502, a transmission chain 503, and a control cabinet 504. The output end of the drive motor 501 is connected to the input end of the gearbox 502, the output end of the gearbox 502 is connected to the transmission chain 503, the transmission chain 503 is connected to the bottom of the moving platform 301, and the control cabinet 504 is located at the bottom of the frame 1. The control cabinet 504 contains a control circuit (shown in the figure), and the control circuit is electrically connected to the drive motor 501. More specifically, the drive motor 501 and the gearbox 502 can be connected by a chain drive. A rotating shaft 505 is provided at both ends of the frame 1, and a transmission sprocket 506 is provided on the rotating shaft 505. A transmission chain 503 is fitted onto the transmission sprockets 506 at both ends. A drive sprocket 507 is also provided on one side of the rotating shaft 505. The output end of the gearbox 502 is also connected to the drive sprocket 507 by a chain drive, thereby driving the rotation of the transmission chain 503. The drive motor 501 is an asynchronous motor, and the control circuit includes a circuit for controlling the forward and reverse rotation of the drive motor 501, enabling the drive motor 501 to drive the transmission chain 503 to rotate forward and reverse, thereby driving the moving platform 301 to reciprocate and push materials.

[0036] When using this invention to split bamboo, the operator places the bamboo 6 to be split onto the V-shaped support plate 2035. The pusher 201 pushes the top rod 202 to carry the bamboo 6 vertically upward. During the upward movement of the top rod 202, the connecting rods 205 on both sides pull the clamping rods 203 on both sides to move upward synchronously within the guide sleeve 204. During the upward movement of the clamping rods 203 on both sides, the V-shaped grooves 2034 at the top gradually approach and close. When the center line of the bamboo 6 is aligned with the center of the cutter head assembly 4 and the pusher assembly 3, the V-shaped grooves 2034 on both sides clamp the bamboo 6 for positioning. Driven by the power component 5, the pusher assembly 3 moves towards the cutter head assembly 4 to push the material. After the pusher assembly 3 pushes the bamboo 6 against the cutter head assembly 4, the pusher 201 descends and drives the clamping rods 203 downward to release the bamboo 6. The pusher assembly 3 continues to push the bamboo 6 towards the cutter head assembly 4 to complete the splitting of the bamboo.
