[0002] The bamboo processing flow is as follows: cutting bamboo, removing inner nodes, softening, washing, constant temperature, rotary cutting, length setting, mesh belt drying, gluing, hot pressing, shaping, polishing, painting, sterilization, inspection, packaging, and warehousing; a bamboo rotary cutting machine is a device that rotary cuts cut and boiled bamboo into thin slices.

[0003] In existing technologies, workers need to manually fix the bamboo into the clamping plate, start the machine to veneer and slice it. After veneer cutting, the remaining bamboo material still needs to be manually removed from the veneer. The operation is very cumbersome, the work efficiency is low, and a lot of manpower is required. Secondly, during the veneer cutting process, the degree of veneer cutting of the bamboo needs to be observed at all times. When the bamboo is veneered to a certain thickness, the workers need to shut down the machine in time, which further increases the workload of the workers. The existing four-roller bamboo veneer cutting machine does not have automatic loading and unloading functions or veneer cutting degree detection functions. Summary of the Invention

A telescopic rod is fixedly installed at the top of the rotating shaft. The other end of the telescopic rod is fixedly connected to the left end of the wedge-shaped rod. An extrusion rod is fixedly installed at the left end of the rotating shaft. A deflection rod is rotatably connected to the right side of the top of the installation rod via a torsion spring.

[0009] As a further embodiment of the present invention, the driving mechanism includes a shaped rod slidably connected to the rear end of the rotary cutting machine body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention, by setting up a positioning mechanism, allows the feeding mechanism to push a bamboo piece on the material rack into the veneer cutting machine. When the bamboo piece falls into the lower V-shaped bar, the positioning mechanism activates, driving the upper and lower V-shaped bars to move closer together. When both V-shaped bars are tightly fitted with the outer wall of the bamboo piece, the bamboo piece is positioned. At this point, both the front and rear ends of the bamboo piece are aligned with the clamping disc of the veneer cutting machine. The veneer cutting machine then activates, driving the clamping disc to clamp and fix the bamboo piece, thus achieving automatic feeding of the bamboo piece. During the feeding process, no manual alignment is required, greatly reducing the workload of the workers, saving labor costs, and increasing the practicality of the device.

[0015] 2. This invention, through the setting of a detection mechanism, when the bamboo is rotary-cut to a certain thickness, drives the rotary cutter to stop running and drives the clamping plate to release the remaining bamboo material. The remaining material falls downward under the action of gravity. At the same time, the detection mechanism drives the two lower V-shaped rods to move away from each other, making way for the falling remaining material, so that the remaining material can fall smoothly from the equipment without affecting subsequent processing. After the remaining material has fallen, the two lower V-shaped rods move closer to each other and reset. At this time, the feeding mechanism drives another bamboo material on the material rack to be fed. The repeated operation realizes continuous rotary cutting of bamboo. The entire rotary cutting process does not require manual operation, reducing labor costs. At the same time, the production steps are more continuous, greatly improving the efficiency of bamboo rotary cutting. It solves the problem that the existing four-roll bamboo rotary cutter does not have automatic loading and unloading functions and rotary cutting degree detection functions.

[0030] Preferred embodiments of the present invention will be described with reference to the accompanying drawings to provide a full understanding of the invention. Embodiments of the present invention can be varied in many forms, and the scope of the invention is not limited to the embodiments described in the following detailed description. These embodiments are provided to provide a more complete explanation of the invention to those skilled in the art. Therefore, to further emphasize the clear description, the shapes of elements in the drawings may be shown enlarged. In the various drawings, the same reference numerals are assigned to the same parts. Detailed descriptions of well-known functions and structures that are deemed likely to obscure the essence of the invention will be omitted.

[0031] Please see Figures 1-12 The present invention provides a technical solution: a four-roller bamboo veneer cutting machine, including a veneer cutting machine body 1, a support frame 2 fixedly installed at the left end of the veneer cutting machine body 1, a positioning mechanism provided in the middle of the support frame 2, the positioning mechanism is used to position and clamp the bamboo when it falls into the left end of the veneer cutting machine body 1, a detection mechanism is provided at the top of the support frame 2, the detection mechanism is used to drive the positioning mechanism to make way for the excess material and make it fall off when the bamboo is veneered to a certain thickness, a material rack 3 is provided at the left end of the support frame 2, and a feeding mechanism is provided in the middle of the right end of the material rack 3, the feeding mechanism is used to transport one of the bamboo materials in the material rack 3 into the veneer cutting machine body 1 when the positioning mechanism makes way for the excess material;

[0032] The positioning mechanism includes two lifting frames 4 set in the middle of the support frame 2. The support frame 2 passes through the two lifting frames 4 and is slidably connected to them. Two V-shaped rods 5 are set at the ends of the two lifting frames 4 that are close to each other. The two upper V-shaped rods 5 are fixedly connected to the bottom end of the upper lifting frame 4. A lifting gear 6 is rotatably connected to the left front end of the support frame 2. A lifting rack 7 is fixedly installed on the left front end of the two lifting frames 4. The two lifting racks 7 are located on both sides of the lifting gear 6 and mesh with it. A lifting plate 8 is fixedly installed on the left front end of the lower lifting frame 4. An electric push rod 9 is fixedly installed on the left front end of the support frame 2. The output end of the electric push rod 9 passes through the lifting plate 8 and is slidably connected to it. The output end of the electric push rod 9 is connected to the top end of the lifting plate 8 through a tension spring.

[0033] During operation, the feeding mechanism pushes a bamboo piece on the material rack 3 into the veneer body 1 until it falls into the lower V-shaped rod 5. Then, the electric push rod 9 is activated, which pushes the lower lifting frame 4 upward through the tension spring and lifting plate 8. The upward movement of the lower lifting frame 4 pushes the bamboo piece upward through the slider 11 and the lower V-shaped rod 5. At the same time, the upward movement of the lower lifting frame 4 drives the lower lifting rack 7 to move upward. The upward movement of the lower lifting rack 7 drives the upper lifting frame 4 downward through the lifting gear 6 and the upper lifting rack 7. The downward movement of the upper lifting frame 4 drives the two upper lifting racks to move downward. The V-shaped rod 5 moves downward, bringing the upper and lower sets of V-shaped rods 5 closer together. When the V-shaped rods 5 are tightly fitted with the outer wall of the bamboo, the bamboo is positioned. At this time, both the front and rear ends of the bamboo are aligned with the clamping plate of the rotary cutter body 1, thus preparing for the subsequent fixing of the bamboo. When the V-shaped rods 5 are all in contact with the bamboo and the electric push rod 9 is still pushing upward, the two lifting frames 4 are limited by the bamboo and the V-shaped rods 5 and cannot move further. The tension spring at the top of the electric push rod 9 is stretched, making the device applicable to bamboo of different diameters, greatly increasing the applicability of the device.

[0034] When the top of the electric push rod 9 can no longer extend upward, the veneer body 1 drives the clamping plate to clamp and fix the bamboo. When the bamboo is clamped, the electric push rod 9 continues to reset. At this time, the V-shaped rod 5 and the lifting frame 4 reset, and the veneer performs the veneer operation.

[0035] When the bamboo is veneered to a certain thickness, the detection mechanism drives the veneer machine to stop and the clamping plate to release the remaining bamboo material. The start-up and stopping of the veneer machine uses existing mature electronic control technology, which will not be elaborated on here. When the remaining bamboo material is released, it falls downwards under the action of gravity. At the same time, the detection mechanism drives the two lower V-shaped rods 5 to move away from each other, making way for the falling material, so that the material can fall smoothly from the equipment without affecting subsequent processing. After the material has fallen, the two lower V-shaped rods 5 move closer together and reset, at which point the material is loaded. The mechanism drives another bamboo material to be fed onto the material rack 3. The repeated operation realizes continuous rotary cutting of bamboo. No manual operation is required during the entire rotary cutting process, which reduces labor costs. At the same time, the production steps are more consistent, which greatly improves the efficiency of bamboo rotary cutting. By setting up a detection mechanism, the degree of bamboo cutting is made uniform each time, avoiding waste of excess material and over-cutting. This makes the production and processing of bamboo slices more standardized, increases the practicality of the device, and solves the problem that the existing four-roll bamboo rotary cutting machine does not have automatic loading and unloading functions and rotary cutting degree detection functions.

[0036] As a further embodiment of the present invention, the lower lifting frame 4 has sliding grooves 10 on both the front and rear sides, and sliders 11 are slidably connected to the inner side of the sliding grooves 10. The ends of the two sliders 11 that are close to each other are connected to the inner wall of the sliding grooves 10 through tension springs. The bottom ends of the two V-shaped rods 5 on the lower side are fixedly connected to the top ends of the two sliders 11 respectively.

[0037] During operation, when the bamboo is rotary-cut to a certain thickness, the detection mechanism drives the two sliders 11 to move away from each other. The two sliders 11 moving away from each other drive the two lower V-shaped rods 5 to move away from each other, thereby making way for the bamboo scraps. When the detection mechanism stops driving the sliders 11 to move, the sliders 11 are reset under the pull of the tension spring, thereby resetting the two lower V-shaped rods 5.

[0038] As a further embodiment of the present invention, the detection mechanism includes a detection rod 12 slidably connected to the middle of the top end of the support frame 2. The top end of the detection rod 12 is connected to the top end of the support frame 2 via a compression spring. A mounting rod 13 is slidably connected to the left side of the bottom end of the detection rod 12. A detection roller 14 is rotatably connected to the bottom end of the mounting rod 13, and the top end of the mounting rod 13 is connected to the left side of the bottom end of the detection rod 12 via a tension spring. A wedge-shaped rod 15 is slidably connected to the middle of the detection rod 12 via a tension spring. An L-shaped rod 16 is fixedly installed on the bottom surface of the top end of the support frame 2. The inclination of the wedge-shaped rod 15... The inclined plane corresponds to the horizontal end of the L-shaped rod 16. The left side of the detection rod 12 is rotatably connected to the rotating shaft 17. The top end of the rotating shaft 17 is fixedly installed with the telescopic rod 18. The other end of the telescopic rod 18 is fixedly connected to the left end of the wedge rod 15. The left end of the rotating shaft 17 is fixedly installed with the extrusion rod 19. The top right side of the mounting rod 13 is rotatably connected with the deflection rod 20 through a torsion spring. The rear end of the veneer body 1 is provided with a drive mechanism. The drive mechanism is used to drive the two lower V-shaped rods 5 away from each other when the detection rod 12 is reset. The left side of the detection rod 12 is fixedly installed with the pressure block 36.

[0039] During operation, the upper lifting frame 4 moves downward, pushing the detection rod 12 downward synchronously via the pressure block 36. The downward movement of the detection rod 12 causes the wedge rod 15 and the detection roller 14 to move downward. As the detection roller 14 moves downward, it is blocked by the bamboo and gradually approaches the bottom of the detection roller 14. At the same time, the mounting rod 13 moves upward relative to the detection rod 12. As the mounting rod 13 moves, it causes the deflection rod 20 to pass over the pressing rod 19. As the wedge rod 15 moves downward, its inclined surface is pressed by the horizontal end of the L-shaped rod 16. At this time, the wedge rod 15 moves to the left to make way for it until the lifting frame 4 stops moving. At this time, the wedge rod 15 passes over the L-shaped rod 16 and is blocked by it, so it can no longer move upward.

[0040] As the veneer lathe operates, the diameter of the bamboo gradually decreases. At this time, the detection roller 14 gradually moves away from the bottom of the detection rod 12 and moves downward. The downward movement of the detection rod 12 drives the mounting rod 13 and the deflection rod 20 to move downward. The downward movement of the deflection rod 20 squeezes the left end of the extrusion rod 19 and flips it downward. The movement of the extrusion rod 19 pushes the wedge rod 15 to the left through the rotating shaft 17 and the telescopic rod 18 until the bamboo is veneered to the specified thickness. At this time, the right end of the wedge rod 15 moves out from the bottom end of the L-shaped rod 16. The detection rod 12 moves upward under the push of the compression spring to reset. At the same time as the detection rod 12 moves, the veneer lathe stops running and loosens the excess bamboo material. This realizes the automatic detection of the degree of veneer cutting, so that the staff does not need to pay continuous attention to it, which brings convenience to the production and processing.

[0041] When the detection rod 12 is reset, the drive mechanism drives the two V-shaped rods 5 on the lower side to move away from each other, thereby avoiding the positioning mechanism from obstructing the discharge of the residual material and realizing the automatic unloading operation of the residual material.

[0042] As a further embodiment of the present invention, the driving mechanism includes a shaped rod 21 slidably connected to the rear end of the rotary cutting machine body 1. The top of the shaped rod 21 is connected to the top end of the support frame 2 via a tension spring. The top end of the detection rod 12 is slidably connected to a slide rod 22 via a tension spring. The rear end of the slide rod 22 is hingedly connected to a wedge block 23. The wedge block 23 corresponds to the right side of the front end of the shaped rod 21. The bottom end of the lower lifting frame 4 is rotatably connected to a drive gear 24. The bottom ends of the two sliders 11 are fixedly mounted with drive racks 25. The two drive racks 25 are respectively located on both sides of the drive gear 24 and mesh with it. The bottom end of the rear end of the support frame 2 is slidably connected to a drive rod 26. The front end of the drive rod 26 corresponds to the drive rack 25 located at the bottom end of the front slider 11. The bottom end of the shaped rod 21 is hingedly connected to a hinge rod 27. The other end of the hinge rod 27 is hingedly connected to the rear end of the drive rod 26.

[0043] During operation, when the upper lifting plate 8 pushes the detection rod 12 downward, the detection rod 12 drives the sliding rod 22 and the wedge block 23 downward. During the downward movement of the wedge block 23, it makes way for the front end of the irregular rod 21 until the wedge block 23 passes over the irregular rod 21. When the bamboo is rotary cut to a certain thickness and the detection rod 12 moves upward, the upward movement of the detection rod 12 drives the wedge block 23 upward through the sliding rod 22. The upward movement of the wedge block 23 pushes the irregular rod 21 upward. The upward movement of the irregular rod 21 pushes the drive rod 26 forward through the hinge rod 27. The forward movement of the drive rod 26 pushes the lower... The side drive rack 25 moves forward, and the lower drive rack 25 moves forward, driving the upper drive rack 25 to move backward through the drive gear 24. This drives the two sliders 11 to move away from each other. When the two sliders 11 can no longer move away from each other, the shaped rod 21 can no longer move upward. At this time, the inclined surface of the wedge block 23 is squeezed and pushes the slide rod 22 to move backward until the wedge block 23 passes the shaped rod 21. At this time, the shaped rod 21 is no longer pushed and returns to its original position under the pull of the tension spring. At the same time, the two sliders 11 return to their original position under the action of the tension spring, preparing for the next set of rotary cutting operations.

[0044] As a further embodiment of the present invention, the feeding mechanism includes a feeding frame 28 installed at the right end of the material rack 3. A pusher roller 29 is rotatably connected to the middle of the feeding frame 28. The friction between the pusher roller 29 and the feeding frame 28 is relatively large. Two guide rods 30 are fixedly installed at the right end of the feeding frame 28. The right ends of the two guide rods 30 correspond to the two V-shaped rods 5 on the lower side, respectively. A transmission mechanism is provided at the rear end of the feeding frame 28. The transmission mechanism is used to drive the pusher roller 29 to rotate a certain angle when the two V-shaped rods 5 on the lower side approach each other and reset.

[0045] During operation, several neatly arranged bamboo pieces are placed on the top of the material rack 3. When the two lower V-shaped rods 5 approach each other and reset, the transmission mechanism drives the pusher roller 29 to rotate. At this time, the bamboo piece at the top of the pusher roller 29 is moved and falls into the lower V-shaped rod 5 along the guide rod 30. At the same time, another bamboo piece at the top of the material rack 3 is moved to the top of the pusher roller 29, thus preparing for the next feeding operation. By setting the pusher roller 29, bamboo pieces are fed into the V-shaped rod 5 one by one, which brings convenience to the feeding of bamboo pieces.

[0046] As a further embodiment of the present invention, the transmission mechanism includes a rotating rod 31 fixedly installed at the rear end of the pusher roller 29, a gear ring 32 rotatably connected to the outer side of the rear end of the rotating rod 31 through a one-way bearing, a transmission rod 33 fixedly installed at the left end of the irregular rod 21, a transmission rack 34 fixedly installed at the left end of the transmission rod 33, and the transmission rack 34 meshing with the gear ring 32.

[0047] During operation, when the shaped rod 21 is pushed upward by the wedge block 23, the upward movement of the shaped rod 21 drives the transmission rack 34 to move upward through the transmission rod 33. The upward movement of the transmission rack 34 drives the gear ring 32 to rotate. The rotation of the gear ring 32 does not drive the rotating rod 31 to rotate under the action of the one-way bearing. When the shaped rod 21 is no longer pushed and moves downward, the downward movement of the shaped rod 21 drives the transmission rack 34 to move downward through the transmission rod 33. The downward movement of the transmission rack 34 pushes the gear ring 32 to rotate in the opposite direction. The rotation of the gear ring 32 in the opposite direction drives the rotating rod 31 to rotate under the action of the one-way bearing. The rotation of the rotating rod 31 drives the pusher roller 29 to rotate, thus providing power for the rotation of the pusher roller 29.

[0048] As a further embodiment of the present invention, a receiving rack 35 is fixedly installed at the bottom center of the material rack 3, and the right end of the receiving rack 35 is located between the two V-shaped rods 5 on the lower side. During operation, the bamboo scraps fall to the top right end of the receiving rack 35 under the action of gravity. At this time, the bamboo scraps slowly roll to the left along the inclined surface of the receiving rack 35, thereby realizing the collection of the scraps and preventing the bamboo scraps from falling everywhere.

[0049] The embodiments of the present invention described above are merely examples, and those skilled in the art can make various modifications or derive other equivalent embodiments. Therefore, the present invention is not limited to the embodiments mentioned in the above detailed description. Thus, the true scope of protection of the present invention should be determined according to the technical concept of the appended claims. Furthermore, it should be understood that the present invention includes all variations, equivalents, and alternatives to the concept of the present invention as defined by the appended claims.
