Description

Technical Field

[0001] This invention relates to the field of bamboo product processing technology, and more specifically, to a bamboo cutting machine conveying mechanism and a bamboo cutting machine. Background Technology

[0002] Bamboo is widely cultivated and used in China, and bamboo materials are widely applied in building materials, furniture, food, and other everyday items. Bamboo processing methods in China are diverse, and products such as bamboo plywood and reconstituted bamboo are quite mature. However, these methods all suffer from problems such as high raw bamboo processing losses, low utilization rates, and difficulty in guaranteeing the amount of residual material. With the rapid development of the engineered wood products industry in recent years, bamboo materials have not been widely used in engineered wood products due to processing issues. Large quantities of bamboo are instead crushed and processed into low-performance fiberboard.

[0003] Existing slicing equipment is mostly designed for wood slicing and planing. When slicing and planing bamboo, due to the special structure of bamboo, the cutting force of the blade is directed downwards during the slicing process. The bamboo segments are prone to shifting due to the cutting force, causing the blade to make empty cuts. Furthermore, when the blade scrapes across the outer wall of the bamboo during empty cuts, it easily generates a large amount of debris. After prolonged processing, the excessive accumulation of debris can easily damage the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying mechanism for a bamboo slicing machine to alleviate the technical problem in the prior art where excessively thin waste residue easily remains at the cutting edge during the bamboo slicing process, causing equipment failure and damage, and affecting processing and production efficiency.

[0005] The present invention provides a conveying mechanism for a bamboo cutting machine, comprising: a conveying component, a pressing component, and an elastic buffer.

[0006] The conveying assembly forms a conveying channel having a conveying section, a lifting section and an output section, the conveying section, the lifting section and the output section being connected in sequence, the lifting section being inclined upward in a direction away from the conveying section, and the output section being inclined downward in a direction away from the conveying section and used to connect to the cutting device; The pressing assembly includes a pressing element, which is disposed in the conveying channel and moves from the conveying section to the lifting section. The pressing element is adapted to the contour shape of the conveying channel and slides in cooperation with the conveying channel. An elastic buffer is located below the lifting section, and the top of the elastic buffer is in contact with the bottom wall of the lifting section. The conveying section and the lifting section, as well as the lifting section and the output section, are all connected flexibly.

[0007] Furthermore, the conveying assembly includes: a support member, a limiting member, and a conveying member.

[0008] The support includes a conveying section, a bending section, and a feeding section. The conveying section extends horizontally, and its front end is used to place materials. The bending section is inclined upward and its front end is flexibly connected to the end of the conveying section. The feeding section is flexibly connected to the end of the bending section and is inclined downward. The limiting member is located above the support member and spaced apart from the support member, forming a conveying space between the limiting member and the support member; The conveying component is disposed on the support and located within the conveying space, and the conveying direction of the conveying component is the same as the setting direction of the support. The limiting member and the bending portion form the conveying section, and the outer bottom wall of the bending portion abuts against the elastic buffer member.

[0009] Furthermore, the conveying component is a conveyor chain; The conveyor chain is disposed on the support member along the extension direction of the support member.

[0010] Furthermore, the conveyor chain has a limiting part; The limiting part has an outward convex structure and extends away from the support member.

[0011] Furthermore, the pressing assembly also includes a hydraulic drive component; The driving end of the hydraulic drive component is connected to the pressing component, and the driving direction of the hydraulic drive component is the same as the extension direction of the conveying part.

[0012] Furthermore, the elastic buffer is a high-strength spring.

[0013] Another objective of this invention is to provide a bamboo cutting machine, including a cutting blade and a bamboo cutting machine conveying mechanism; The cutting blade is disposed opposite to the bamboo cutting machine conveying mechanism, and the cutting blade has a cutting opening facing the outlet of the lifting section of the bamboo cutting machine conveying mechanism.

[0014] Furthermore, the bamboo cutting machine also includes a waste bin; The waste bin is located below the cutting blade, and the waste bin has a waste discharge port, which is located between the cutting blade and the bamboo cutting machine conveying mechanism and faces upward.

[0015] Furthermore, the cutting tool includes a cutting disc; The cutting disc is provided with multiple cutting openings, the extension direction of which coincides with the diameter of the cutting disc, and the multiple cutting openings are spaced apart along the circumference of the cutting disc.

[0016] Furthermore, the bamboo cutting machine also includes a toothed blade; The toothed blade is disposed within the cutting opening, and the extension direction of the blade edge of the toothed blade is parallel to the diameter of the cutting disc.

[0017] Beneficial effects: In this invention, bamboo segments are conveyed by a conveying assembly. A large number of bamboo segments are placed in the conveying channel formed by the conveying assembly. The pressing component in the pressing assembly presses the bamboo segments towards the output section, ensuring that the bamboo in the conveying channel is kept perpendicular to the conveying direction. The conveying assembly and the pressing assembly work together to press the bamboo in the conveying channel and simultaneously transport the bamboo to the output section. After reaching the lifting section, the bamboo in the conveying channel moves upward along the lifting section and is then conveyed to the cutter for slicing after passing through the output section. The cutter falls to slice the bamboo. When the bamboo is subjected to a downward cutting force, the upward-sloping conveying section presses down on the elastic buffer to offset the cutting force. The pressing component continuously applies pressure to the bamboo in the conveying channel to prevent the bamboo at the front end from shifting, thereby avoiding the cutter from cutting without contact and thus preventing excessive debris accumulation.

[0027] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0028] See Figures 1 to 4 The bamboo cutting machine conveying mechanism provided in this embodiment includes a conveying component 100, a pressing component 200, and an elastic buffer component 300.

[0029] The conveying assembly 100 forms a conveying channel with a conveying section, a lifting section, and an output section. The conveying section, lifting section, and output section are connected sequentially. The lifting section is inclined upwards in a direction away from the conveying section, and the output section is inclined downwards in a direction away from the conveying section and is used to connect to the cutting device. The pressing assembly 200 includes a pressing member 210, which is disposed in the conveying channel and moves from the conveying section to the lifting section. The pressing member 210 is adapted to the contour shape of the conveying channel and slides in cooperation with the conveying channel. An elastic buffer member 300 is disposed below the lifting section, and the top end of the elastic buffer member 300 is in contact with the bottom wall of the lifting section.

[0030] Furthermore, in this embodiment, the connections between the conveying section and the lifting section, and between the lifting section and the output section, are flexible.

[0031] Specifically, in this embodiment, the bamboo cutting machine conveying mechanism is used to connect with the slicing device of the bamboo cutting machine. When conveying raw materials, the bamboo needs to be cut into segments and then placed into the conveying space of the conveying component 100, which then conveys the segments of bamboo.

[0032] A large number of bamboo segments are placed in the conveying channel formed by the conveying assembly 100. The pressing component 210 in the pressing assembly 200 pushes the bamboo segments towards the output section and compresses the bamboo in the conveying channel. Under compression, the bamboo in the conveying channel can maintain an axial position perpendicular to the conveying direction. After reaching the lifting section, the bamboo in the conveying channel moves upward along the lifting section and is then conveyed to the cutter for slicing after passing through the output section.

[0033] During the slicing process, the cutter falls to slice the bamboo. The bamboo is subjected to a downward cutting force. At this time, the upward-sloping conveyor section is also subjected to force to press down on the elastic buffer 300 to counteract the cutting force. The pressing component 210 can continuously apply pressure to the bamboo in the conveying channel to prevent the bamboo at the front end from moving around while being cut, thereby avoiding the cutter from cutting without contact and thus avoiding the accumulation of too much debris.

[0034] In addition, the end of the lifting section in this embodiment is connected to an output section that is inclined downwards. When thin waste is generated after the bamboo is cut, the thin waste can fall out of the output section, preventing the thin waste from falling back into the conveying channel and accumulating.

[0035] In this embodiment, the conveying assembly 100 includes a support member 110, a limiting member 120, and a conveying member 130. The conveying section 111 extends horizontally, with its front end for feeding material. A bending section 112 is inclined upward and its front end is flexibly connected to the end of the conveying section 111. The feeding section 113 is flexibly connected to the end of the bending section 112 and is inclined downward. The limiting member 120 is located above the support member 110 and spaced apart from it, forming a conveying space between the limiting member 120 and the support member 110. The conveying member 130 is located on the support member 110 and within the conveying space, with the conveying direction of the conveying member 130 being the same as the orientation of the support member 110.

[0036] In this embodiment, the limiting member 120 and the bending part 112 form a conveying section, and the outer bottom wall of the bending part 112 abuts against the elastic buffer member 300.

[0037] Specifically, in this embodiment, the support member 110 and the limiting member 120 are spaced apart and enclose each other, forming a conveying space for conveying bamboo between the support member 110 and the limiting member 120. The bamboo is conveyed by the conveying member 130 provided on the support member 110, so that the bamboo moves from the conveying part 111 to the bending part 112 and finally reaches the delivery part 113 for output to the cutting device.

[0038] Since the bending part 112 and the conveying part 111, and the bending part 112 and the delivery part 113 are all flexibly connected, they can deform at the connection when subjected to the cutting force given by the cutter, thereby transmitting the pressure to the elastic buffer 300 and thus offsetting the cutting force applied to the bamboo by the cutter.

[0039] In this embodiment, the conveying member 130 is a conveying chain. The conveying chain is disposed on the support member 110 along the extending direction of the support member 110.

[0040] Specifically, in this embodiment, the conveying chain is disposed on the support member 110. The conveying part 111 of the conveying chain is located on the upper surface of the support member 110 and passes through the conveying part 111, the bending part 112 and the delivery part 113 in sequence. The return section of the chain is disposed on the lower surface of the support member 110 and passes through the delivery part 113, the bending part 112 and the conveying part 111 in sequence, thereby realizing the conveying of bamboo and the resetting of the chain.

[0041] Furthermore, the segments of the chain can rotate relative to each other. When rotation occurs between the conveying section 111 and the bending section 112 or between the bending section 112 and the delivery section 113, the chain can rotate accordingly. This allows for stable conveying of the bamboo while also allowing the chain to deform along with the support member 110 to provide cushioning and thus counteract the cutting force applied by the cutter.

[0042] In this embodiment, the conveyor chain has a limiting portion 131. The limiting portion 131 has an outward convex structure and extends in a direction away from the support member 110.

[0043] The limiting part 131 can limit the bamboo on the conveyor chain, so that the bamboo can move with the chain and avoid the bamboo rolling on the chain, which would result in low conveying efficiency.

[0044] In this embodiment, the pressing assembly 200 further includes a hydraulic drive 220. The driving end of the hydraulic drive 220 is connected to the pressing assembly 210, and the driving direction of the hydraulic drive 220 is the same as the extending direction of the conveying section 111.

[0045] In this embodiment, the pressure member 210 is driven by the hydraulic drive member 220 so that the pressure member 210 can reciprocate along the conveying channel.

[0046] Furthermore, specifically, the elastic buffer 300 in this embodiment is a high-strength spring.

[0047] High-strength springs, acting as elastic buffer components 300, provide powerful, stable, reliable, and controllable cushioning capabilities. These springs efficiently absorb the impact energy generated by cutting forces, effectively suppressing bamboo movement, preventing air cutting and debris generation, and ensuring the equipment maintains excellent performance and durability during long-term, high-intensity continuous operation.

[0048] The bamboo cutting machine provided in this embodiment includes a cutting blade 400 and a bamboo cutting machine conveying mechanism. The cutting blade 400 is disposed opposite to the bamboo cutting machine conveying mechanism, and the cutting blade 400 has a cutting opening facing the outlet of the lifting section of the bamboo cutting machine conveying mechanism.

[0049] In this embodiment, the cutting edge of the cutting tool 400 is opposite to the outlet of the lifting section of the bamboo cutting machine conveying mechanism, and there is a certain gap between them to avoid the outlet of the lifting section colliding with the cutting tool 400.

[0050] In this embodiment, the bamboo cutting machine also includes a waste bin. The waste bin is located below the cutting blade 400 and has a waste discharge opening, which is located between the cutting blade 400 and the bamboo cutting machine conveying mechanism and faces upward.

[0051] When cutting bamboo to the end, some thin bamboo pieces may remain and not be able to enter the cutting blade 400 under the conveying mechanism of the bamboo cutter. Instead, they may fall through the gap between the bamboo cutter's conveying mechanism and the cutting blade 400.

[0052] In this embodiment, the waste discharge opening of the waste bin faces upward and is located between the bamboo cutting machine conveying mechanism and the cutting blade 400. When residual bamboo pieces fall, they can fall directly into the waste bin, avoiding the accumulation of residual waste in the bamboo cutting machine conveying mechanism.

[0053] In this embodiment, the cutting tool 400 includes a cutting disc 410. The cutting disc 410 is provided with a plurality of cutting openings, the extension direction of which coincides with the diameter of the cutting disc 410, and the plurality of cutting openings are spaced apart along the circumference of the cutting disc 410.

[0054] Specifically, in this embodiment, the cutting disc 410 is disc-shaped, with multiple cutting openings spaced circumferentially and evenly arranged on the surface of the cutting disc 410, and a drive shaft connected to the center of the cutting disc 410.

[0055] During slicing, the bamboo slicer's conveying mechanism pushes the bamboo into the cutting opening, and the cutting disc 410 rotates to slice the bamboo.

[0056] In this embodiment, the bamboo cutter also includes a toothed blade 420.

[0057] In this embodiment, the toothed blade 420 is disposed inside the cutting opening, and the extension direction of the blade of the toothed blade 420 is parallel to the diameter of the cutting disc 410.

[0058] Bamboo fibers are long and have high longitudinal strength, but weak transverse bonding. When cutting with a flat-bladed knife, the blade needs to cut all the fibers in one go, which can easily cause the bamboo to crack along the fiber direction due to stress concentration.

[0059] In this embodiment, the toothed blade 420 has a serrated edge. By applying concentrated local high pressure, it cuts the fibers in a gradual "point-to-line" manner. Each tooth tip is pressed into the bamboo wall first to separate the fiber bundles, ensuring a smooth cut and preventing the bamboo from splitting as a whole during the slicing process.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
