Description

Technical Field

[0001] This utility model relates to the field of bamboo flute processing technology, specifically to a high-efficiency drying device for pretreatment in bamboo flute making. Background Technology

[0002] The bamboo flute is a traditional Chinese wind instrument, named for its primary material, bamboo. Its history can be traced back to the Neolithic Age, making it one of the oldest musical instruments in Chinese civilization. A bamboo flute is typically made from a single bamboo tube with a blowhole, a membrane hole, finger holes, and a sound hole. A reed membrane is attached to the membrane hole; when played, it vibrates to produce a clear, bright, and penetrating tone, capable of expressing both melodious tunes and lively, cheerful melodies.

[0003] In the pre-processing stage of bamboo flute making, drying and straightening are crucial steps that determine the quality of the instrument. Fresh bamboo contains a large amount of moisture, and direct processing can easily lead to cracking and deformation. Excess moisture must be removed through precise temperature control, while external force is used to correct the natural curvature of the bamboo. Currently, most handmade flutes use traditional techniques, either baking over charcoal or using electric heating devices, relying entirely on the craftsman to continuously rotate the bamboo to heat it. This method is not only labor-intensive, but prolonged hand handling can easily cause fatigue for the craftsman, and it is also difficult to ensure even heating of all parts of the bamboo. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a high-efficiency drying device for the pretreatment of bamboo flute making that does not require manual rotation for a long time and produces uniform drying.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a high-efficiency drying device for pretreatment in bamboo flute making, comprising:

[0006] The drying rack includes a base plate and a carrier plate. The carrier plate is arranged parallel to the base plate and has a heating groove in the center. It is driven to rise and fall by a cylinder fixed on the carrier plate.

[0007] The drying assembly is fixedly mounted on the base plate and located below the carrier plate, including a first drying oven and a second drying oven;

[0008] The clamping mechanism includes a clamping seat and a movable plate. The movable plate is slidably disposed on one side of the heating channel above the carrier plate and is located close to the first drying oven. It is driven by an electric push rod fixed on the carrier plate. The clamping seat is disposed on one side of the movable plate and is driven to rotate by a reduction motor fixed on the movable plate. Tightening bolts are provided on its side wall.

[0009] Support plates are symmetrically fixed on both sides of the heating channel above the carrier plate and are located close to the second drying oven. They are provided with arc-shaped support grooves, and the support grooves on the two support plates are coaxially arranged.

[0010] The straightening tube is fixedly installed above the carrier plate near the side edge of the support plate.

[0011] Furthermore, two cylinders are symmetrically arranged above the base plate and work synchronously. The base plate and the carrier plate are connected at their four corners by guide telescopic rods.

[0012] Furthermore, the first and second drying ovens are equipped with temperature control knobs.

[0013] Furthermore, a slide bar is integrally formed below the movable plate, and a guide groove matching the slide bar is provided on the carrier plate.

[0014] Furthermore, the tightening bolts are equidistantly arranged around the center of the clamping seat, with their ends passing through the side wall of the clamping seat and connected to a protective block.

[0015] Furthermore, protective pads are provided at both ends of the straightening tube.

[0016] Compared with existing technologies, this invention has the following advantages: the geared motor in the clamping mechanism drives the clamping seat to rotate, causing the bamboo flute to rotate automatically, replacing manual operation. This greatly reduces labor intensity and improves work efficiency during the initial drying stage. The first and second drying ovens of the drying assembly can be independently temperature-controlled, allowing for the setting of appropriate temperatures for bamboo flutes in different states to ensure drying results. Simultaneously, the carrier plate is lifted and lowered by a cylinder, allowing for flexible adjustment of the distance between the bamboo flute and the drying oven, thus precisely controlling the heating temperature. During rotation, the bamboo flute receives heat from all directions without any blind spots, ensuring uniform heating of all parts and preventing localized over-drying or under-drying, thus guaranteeing the consistency and quality stability of the bamboo flute drying process.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 Appendix Figure 4 A high-efficiency drying device for pre-treatment in bamboo flute making includes: a drying rack, comprising a base plate 1 and a carrier plate 2. The carrier plate 2 is arranged parallel above the base plate 1, with a heating groove in its center. It is driven to rise and fall by cylinders 3 fixed on the carrier plate 2. Two cylinders 3 are symmetrically arranged above the base plate 1 and operate synchronously. The base plate 1 and the carrier plate 2 are connected at their four corners by guide telescopic rods 13 to ensure smooth raising and lowering of the carrier plate 2, preventing tilting or jamming. The four corner guide telescopic rods 13 enhance stability, ensure the positional accuracy of the bamboo flute during the drying process, and improve the consistency of the drying effect.

[0024] Combined with appendix Figure 2 Appendix Figure 3 The drying assembly is fixed on the base plate 1 and located below the carrier plate 2. It includes a first drying oven 4 and a second drying oven 5. The first drying oven 4 and the second drying oven 5 are equipped with temperature control knobs 14, which can independently control the temperature and are suitable for drying bamboo flutes in different states.

[0025] Combined with appendix Figure 1 Appendix Figure 3 The clamping mechanism includes a clamping seat 6 and a movable plate 7. The movable plate 7 is slidably disposed on one side of the heating channel above the carrier plate 2 and is located close to the first drying oven 4. It is driven by an electric push rod 8 fixed on the carrier plate 2. A slide bar is integrally formed below the movable plate 7. The carrier plate 2 is provided with a guide groove 15 that matches the slide bar, so that the movable plate 7 slides more smoothly in a straight line, reduces frictional resistance, ensures accurate positioning when the clamping seat 6 moves, and facilitates the quick alignment of the bamboo flute to be dried with the drying oven, thereby improving operating efficiency.

[0026] Combined with appendix Figure 2 Appendix Figure 4 The clamping seat 6 is located on one side of the movable plate 7 and is driven to rotate by a reduction motor 9 fixed on the movable plate 7. A tightening bolt 10 is provided on its side wall. The tightening bolt 10 is equidistantly arranged around the center of the clamping seat 6, and its end passes through the side wall of the clamping seat 6 and is connected to a protective block 16. This achieves a uniform clamping force on the bamboo flute, preventing excessive localized force from damaging the bamboo. The protective block 16 prevents the bolts from directly contacting the surface of the bamboo flute, protecting its appearance.

[0027] Combined with appendix Figure 1 Appendix Figure 3 The support plate 11 is symmetrically fixed on both sides of the heating channel above the carrier plate 2 and is located close to the second drying oven 5. It is provided with an arc-shaped support groove. The support grooves on the two support plates 11 are coaxially arranged, which can quickly and accurately determine the straightness of the bamboo flute.

[0028] Combined with appendix Figure 1 Appendix Figure 3 The straightening tube 12 is fixedly installed above the carrier plate 2 near the side edge of the support plate 11. Protective pads are provided at both ends of the straightening tube 12 to buffer the impact force when the bamboo flute is inserted, prevent the edge of the tube from being damaged by collision, and also prevent the edge of the straightening tube 12 from damaging the bamboo flute during straightening.

[0029] The specific implementation of this utility model is as follows: The device is connected to an external power source. The bamboo flute is placed in the clamping seat 6, and the flute is evenly clamped by the tightening bolts 10 and the protective block 16. The electric push rod 8 drives the moving plate 7, causing the clamping seat 6 to slide, positioning the part of the bamboo flute to be dried directly above the first drying oven 4. The control cylinder 3 is used to adjust the height of the carrier plate 2 from the bottom plate 1. The reduction motor 9 is started, causing the clamping seat 6 to automatically rotate the bamboo flute. The first drying oven 4 is set to a suitable temperature via the adjusting knob 14, and initial drying begins.

[0030] After initial drying, the bamboo flute is removed from the clamping seat 6 and placed into the arc-shaped support groove of the support plate 11. The part of the bamboo flute to be dried is aligned with the second drying oven 5. The temperature of the second drying oven 5 is set for secondary drying. During the process, the bamboo flute is manually rotated, and its degree of bending is observed. The bent part is placed in the straightening tube 12 and bent to straighten it. Then it is placed back on the support plate 11 for continued drying. After multiple straightenings, it is ready to be dried. During the drying process, the bamboo flute rotates continuously, ensuring uniform heating from all directions, thus ensuring consistent drying results and improving the quality and efficiency of the bamboo flute pre-treatment drying.
