Description

Technical Field

[0001] This utility model relates to the field of bamboo processing technology, and more specifically, to a bamboo splitting machine that does not require adjustment of thickness. Background Technology

[0002] The bamboo splitting machine is an automated device specifically designed for handicrafts such as bamboo weaving and reed weaving, as well as related large-scale production. Its core function is to replace traditional hand-operated bamboo knives, enabling efficient and precise splitting of tough plant stems such as bamboo and reeds that have undergone pre-treatment (removing branches, cutting, and peeling). It can flexibly adjust parameters according to processing needs, stably producing bamboo strips of various specifications with uniform thickness and meeting toughness standards (such as fine strips for bamboo mats as thin as 0.1mm and coarse strips for bamboo baskets as thick as 1mm). This not only significantly improves the efficiency of bamboo strip processing (far superior to manual operation) but also strictly ensures the consistency of finished product specifications, providing standardized basic raw materials for subsequent weaving processes. This effectively addresses the industry pain points of low efficiency and large dimensional deviations associated with traditional hand-operated bamboo splitting.

[0003] Existing bamboo splitting machines mainly consist of a frame, a feeding mechanism, a layering mechanism, and a transmission mechanism. Bamboo is smoothly fed in by the feeding mechanism, precisely guided, and then enters the layering mechanism for layering processing before being finally extracted. Newly split bamboo strips are prone to loosening, shifting, or even tangling due to uneven tension. This not only affects the smoothness of extraction but may also lead to edge wear and dimensional deviations. Therefore, to effectively limit and tighten the bamboo strips, ensure a stable and orderly extraction process, and further ensure uniform thickness and edge flatness, a tensioning wheel mechanism is usually added at the blade position of the layering mechanism. However, the existing tensioning wheel mechanism still has significant drawbacks: it consists of two tensioning wheels symmetrically distributed on both sides of the blade. The two tensioning wheels require independent manual adjustment to adjust their spacing, which is not only cumbersome but also prone to poor synchronization of adjustments on both sides, making it difficult to accurately control the tension and guiding accuracy of the bamboo strips.

[0011] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects: In the bamboo slicing machine of this application, synchronous gears meshing at the rotation center of two lever structures enable synchronous linkage of the two levers, thereby driving the tensioning wheels symmetrically arranged on both sides of the layering blade to move precisely towards or away from each other. At the same time, by screwing on the first rubber pad bolt connected to the second end of one of the levers, the tensioning wheel spacing can be flexibly adjusted by the resistance between the first rubber pad and the elastic rubber pad at the end of the other lever.

Detailed Implementation

[0015] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0016] Please refer to Figures 1-6 This application provides a bamboo slicing machine, comprising: a frame 1; a feeding mechanism including a feeding trough 17 and two drive wheels 11, both of which are rotatably mounted on the frame 1 and are parallel to each other and spaced apart to form a guide channel for bamboo to pass through, the feeding trough 17 being disposed on the feeding side of the guide channel; a power mechanism for driving the two drive wheels 11 to rotate; a stratification mechanism including a stratification blade 13, the stratification blade 13 being disposed on the discharge side of the guide channel for stratifying the bamboo output from the guide channel; and a tensioning mechanism including two tensioning wheels 16, two lever structures 6, and an elastic rubber pad. 3. The two tensioning wheels 16 are symmetrically arranged on both sides of the cutting edge of the layering knife 13 and can move towards or away from each other. The two lever structures 6 are both mounted on the frame 1, and their first ends are respectively connected to the two tensioning wheels 16 to drive the tensioning wheels 16 to move towards or away from each other. The elastic rubber pad 3 is provided at the second end of one of the lever structures 6, and the second end of the other lever structure 6 is threadedly connected to a first rubber pad bolt 5, which abuts against the elastic rubber pad 3. The rotation center of the two lever structures 6 is provided with a synchronous gear 7, and the two synchronous gears 7 mesh with each other.

[0017] In the bamboo slicing machine of this application, the synchronous gears 7 meshing at the rotation center of the two lever structures 6 enable the levers on both sides to move synchronously, thereby driving the tensioning wheels 16 symmetrically arranged on both sides of the cutting edge of the layering knife 13 to move precisely towards or away from each other. At the same time, by screwing the first rubber pad bolt 5 which is threaded to the second end of one of the levers, the tensioning wheel 16 can be flexibly adjusted by the action of the first rubber pad 5 against the elastic rubber pad 3 at the end of the other lever. The elastic buffering characteristics of the rubber pad are used to achieve flexible control of the tension force. Combined with the material guide channel driven by the power wheel 11 in the feeding mechanism, the material is fed smoothly and the layering knife 13 cuts precisely, forming a continuous process of "stable feeding - precise cutting - synchronous tensioning and output". The advantages of this solution are as follows: the meshing structure of the synchronous gear 7 completely solves the problem of poor synchronization of the existing independent adjustment of the tensioning wheel 16 from a mechanical principle perspective, ensuring precise and synchronized adjustment of the tensioning wheels 16 on both sides; the adjustment method of a single bolt with elastic rubber pad 3 replaces the traditional dual independent adjustment, making operation simpler and more efficient, and the elastic buffer can avoid wear of the bamboo strips caused by excessive tension, which not only ensures the stability and order of the bamboo strip output process and effectively prevents loosening, deviation or tangling, but also further improves the uniformity of bamboo strip thickness and edge flatness, significantly optimizing the processing quality and ease of operation.

[0018] Optionally, the number of the aforementioned power mechanism and tensioning mechanism may be multiple.

[0019] In a preferred embodiment, the power mechanism includes a drive motor 2, which is driven by a first planar gear 18. The first planar gear 18 meshes with a second planar gear 19, and the first planar gear 18 and the second planar gear 19 are respectively driven by two power wheels 11.

[0020] In the above embodiment, the precise meshing of the first planar gear 18 and the second planar gear 19 enables the power of the drive motor 2 to be transmitted synchronously and evenly to the two power wheels 11. From a mechanical structure perspective, this ensures that the rotational speeds of the two power wheels 11 are completely consistent, thus completely avoiding the problems of bamboo material feeding deviation and jamming caused by the speed difference that may occur in traditional transmission methods. This ensures that the bamboo material is transported smoothly and at a uniform speed along the guide channel, laying the foundation for the subsequent precise splitting by the layering knife 13.

[0021] In a preferred embodiment, both of the aforementioned drive wheels 11 are slidably mounted on the aforementioned frame 1, and each of the aforementioned drive wheels 11 is connected to a second rubber pad bolt 8 for adjusting the distance between the two aforementioned drive wheels 11; wherein, the first planar gear 18 and the corresponding aforementioned drive wheel 11, and the second planar gear 19 and the corresponding aforementioned drive wheel 11 are all connected by a first universal joint 9.

[0022] In the above embodiment, by designing the two drive wheels 11 as a structure that can slide along the frame 1, and cooperating with the second rubber pad bolt 8 connected to each drive wheel 11, rotating the bolt can push the drive wheel 11 to move in the sliding direction, thereby flexibly adjusting the spacing of the material guide channel between the two drive wheels 11 to adapt to bamboo materials of different diameters; at the same time, since the spacing adjustment will cause the installation distance or transmission angle between the first planar gear 18, the second planar gear 19 and the corresponding drive wheel 11 to change, the transmission connection between the gear and the drive wheel 11 is realized through the first universal joint 9, which can effectively compensate for the transmission deviation caused by the spacing adjustment, and ensure that the power transmitted by the gear meshing can be stably transmitted to the drive wheel 11 without affecting the synchronous rotation characteristics of the two wheels. Its advantages are as follows: it retains the core advantage of "dual-plane gear transmission" to ensure synchronous power, and through the combination of adjustable power wheel 11 and universal joint, it achieves precise adaptation to bamboo materials of different specifications, completely solving the problem that fixed-spacing power wheel 11 cannot be compatible with bamboo materials of different thicknesses; the universal joint transmission structure is stable and has low power loss, which can avoid transmission jamming and uneven power after spacing adjustment, ensuring that bamboo materials are always fed smoothly and at a uniform speed, further improving the subsequent splitting accuracy. At the same time, the adjustment operation is simple and convenient, and the adaptability and practicality are greatly improved.

[0023] Preferably, the second rubber pad bolt 8 is threaded onto the frame 1 to drive the sliding of the drive wheel 11. Both ends of each drive wheel 11 are fitted with the second rubber pad bolt 8.

[0024] In a preferred embodiment, each of the tensioning wheels 16 is rotatably mounted on the corresponding lever structure 6; wherein, the drive motor 2 is also connected to a third planar gear 20, the third planar gear 20 meshes with a fourth planar gear 21, and the third planar gear 20 and one of the tensioning wheels 16, and the fourth planar gear 21 and the other tensioning wheel 16 are all connected by a second universal joint 10.

[0025] In the above embodiment, each tensioning wheel 16 is rotatably mounted on the corresponding lever structure 6. At the same time, the drive motor 2 synchronously drives the third planar gear 20. Through the meshing of the third planar gear 20 and the fourth planar gear 21, and with the help of the second universal joint 10, the power transmission between the third planar gear 20 and one of the tensioning wheels 16, and between the fourth planar gear 21 and the other tensioning wheel 16 are realized respectively. Combined with the synchronous gears 7 meshing at the rotation center of the lever structure 6 to ensure the synchronous movement of the tensioning wheels 16 towards / away, this design can ensure that the two tensioning wheels 16 obtain synchronous and uniform rotational power through gear meshing, and can flexibly compensate for the transmission angle or distance deviation caused by the spacing adjustment of the tensioning wheels 16 through the second universal joint 10, realizing the dual synergy of "synchronous movement + synchronous rotation". Moreover, the power comes from the same drive motor 2, which is linked with the power of the feeding mechanism. Its advantages are as follows: the tensioning wheel 16 actively rotates instead of passively frictioning, significantly reducing the friction between it and the bamboo strips, effectively preventing wear and fuzzing of the bamboo strip edges; the precise meshing of the third plane gear 20 and the fourth plane gear 21 ensures that the rotation speeds of the two tensioning wheels 16 are completely consistent, and with the synchronous movement of the lever gear, it completely solves the problem of offset and loosening caused by asynchronous movement of the tensioning wheels 16 when the bamboo strips are unloaded; the second universal joint 10 adapts to the dynamic requirements of tensioning wheel 16 spacing adjustment, ensuring stable and smooth power transmission, and not affecting rotational synchronization due to spacing adjustment; the integrated power design makes the equipment structure more compact, reduces the need for additional power sources, and has stronger power coordination with the feeding mechanism, further improving the smoothness and processing accuracy of bamboo strip unloading, while reducing equipment maintenance costs.

[0026] In a preferred embodiment, a push plate 4 is provided on the side of the first rubber pad bolt 5 facing the elastic rubber pad 3.

[0027] In the above embodiment, the push plate 4 provided on the side of the first rubber pad bolt 5 facing the elastic rubber pad 3 can increase the contact area between the bolt and the rubber pad, avoid local pressure deformation or damage to the rubber pad, make the tension adjustment pressure transmission more uniform, and improve the stability and accuracy of adjustment.

[0028] In a preferred embodiment, the drive motor 2 is disposed at the bottom of the frame 1. The output shaft of the drive motor 2 is provided with a first transmission flywheel 12. The first transmission flywheel 12 is connected to a second transmission flywheel 15 via a belt 14. The second transmission flywheel 15 is coaxially connected to a fifth planar gear 22. The fifth planar gear 22 meshes with both the first planar gear 18 and the third planar gear 20.

[0029] In the above embodiment, the drive motor 2 is located at the bottom of the frame 1. Through the design of the first transmission flywheel 12, belt 14, second transmission flywheel 15 and fifth planar gear 22 simultaneously meshing with the first planar gear 18 and the third planar gear 20, a single power source can synchronously drive the feeding mechanism and the tensioning mechanism. This simplifies the equipment structure, reduces costs, optimizes the spatial layout of the frame 1, and improves the stability and coordination of power transmission.
