Description

Technical Field

[0001] The utility model belongs to the technical field of bamboo flute tube stock processing equipment, and particularly relates to a heating device for bamboo flute tube stock. Background Art

[0002] The flute is an ancient wind instrument and one of the representative instruments of Chinese music. Bamboo has a dense structure, a smooth texture, good vibration performance, a clear sound, and is easy to process, making it a good material for making flutes. Therefore, bamboo flutes are widely used. Since bamboo flutes have high requirements for the straightness of materials, the original bamboo used as the source of bamboo flute tube stock may bend or deform during growth or drying, resulting in a low utilization rate of bamboo flute tube stock and affecting the processing quality of bamboo flutes.

[0003] Therefore, before making bamboo flutes, it is necessary to stretch and straighten the bamboo flute tube stock first, but it is necessary to heat and soften it before stretching and straightening. At present, the traditional softening method for bamboo flute tube stock is to heat and soften the bamboo flute tube stock by burning firewood or coal. On the one hand, the above heating method will cause the bamboo flute tube stock to be unevenly heated, resulting in a low straightening degree and utilization rate of the bamboo flute tube stock, and further resulting in a low utilization rate of the bamboo flute tube stock, making it difficult to ensure the quality of the bamboo flute in later production, such as color, intonation, and timbre. On the other hand, the burning of firewood and coal will also cause environmental pollution. Summary of the Invention

[0004] Aiming at the above disadvantages, the utility model provides a heating device for bamboo flute tube stock, which can circularly heat the bamboo flute tube stock, with more uniform heating, and uses an electric heating wire for heating, which is more environmentally friendly.

[0005] The invention purpose of the utility model is realized through the following technical solutions: a heating device for bamboo flute tube stock, including a heater and a support frame for supporting the heater. The heater includes a frame with a circular ring structure. A plurality of cavities are arranged in the frame in a circumferential array around the center line of the frame. Electric heating wires are installed in the cavities. A plurality of through grooves are distributed on the inner wall of the frame in a circumferential array around the center line of the frame, and the through grooves are communicated with the cavities.

[0006] Preferably, the length direction of the through groove is parallel to the center line of the frame.

[0007] Preferably, at least two through grooves are communicated with each cavity.

[0008] Preferably, all the electric heating wires are connected in parallel.

[0009] Preferably, the center line of the frame is inclined relative to the horizontal plane.

[0010] Preferably, the inclination angle of the center line of the frame relative to the horizontal plane is 30°, and the height of the support frame is 60-80 cm.

[0011] Preferably, the cavity communicates with the higher end of the frame.

[0012] Preferably, a heat preservation shell is fixedly arranged on the outer side of the frame.

[0013] Preferably, a support rod with adjustable length is also fixedly arranged on the support frame. The length direction of the support frame intersects with the center line of the frame. A bracket for supporting the bamboo flute blank is arranged at the upper end of the support rod.

[0014] Preferably, the bracket is an arc-shaped structure with an upward opening, and the bracket is fixedly arranged at the upper end of the support rod.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, the heater as a whole is a circular ring structure, which can uniformly heat the bamboo flute blank extending into the heater, and adopts the heating method of electric heating wire, which is more environmentally friendly than the traditional heating methods of burning firewood and coal;

[0017] 2. The arranged bracket can be used to support the bamboo flute blank, making it more labor-saving for the operator to hold the bamboo flute blank for heating and softening. Description of the Drawings

[0022] The following further describes the utility model in combination with the embodiments shown in the drawings: Embodiment 1

[0023] As Figure 1 、 Figure 2As shown in the figure, a heating device for bamboo flute tube materials includes a heater 1 and a support frame 2 for supporting the heater 1. The heater 1 includes a frame 3 with an annular structure, which is made of iron. There are eight cavities 4 arranged in a circumferential array around the center line of the frame 3 inside the frame 3. Electric heating wires 5 are installed in the cavities 4. A plurality of through grooves 6 are distributed on the inner wall of the frame 3 in a circumferential array around the center line of the frame 3. Each cavity 4 communicates with three through grooves 6, and the length direction of the through grooves 6 is parallel to the center line of the frame 3. A heat preservation shell 7 is fixedly arranged outside the frame 3.

[0024] The center line of the frame 3 is inclined relative to the horizontal plane, and the inclination angle is 30°. The height of the support frame 2 is 60 - 80 cm. The support frame 2 within this height range supports the frame 3. Coupled with the inclined frame 3, the operator can sit to soften the bamboo flute tube materials, which is more convenient and labor-saving.

[0025] The cavity 4 communicates with the higher end of the frame 3. The electric heating wire 5 is an electric heating wire 5 with a power of 2000 - 3000 watts. When the electric heating wire 5 works, its temperature can reach between 700 - 800 °C. At this time, the electric heating wire 5 will glow. Setting the cavity 4 to communicate with the frame 3 can directly observe the electric heating wire 5 in the cavity 4 to judge whether the electric heating wire 5 is damaged, which is convenient for subsequent maintenance and replacement of the damaged heater. All the electric heating wires 5 are connected in parallel. Even if some of the electric heating wires 5 are damaged, the other electric heating wires 5 can still work normally.

[0026] During use, the operator holds the bamboo flute tube material and inserts it into the hollow part of the heater 1 for heating. Using the electric heating wire 5 with a power of 2000 watts or 3000 watts, the heat generated by the working of the electric heating wire 5 can bake and heat the bamboo flute tube material through the through grooves 6 on the frame 3. The electric heating wires 5 in the eight cavities 4 can surround the bamboo flute tube material for circumferential baking and heating through the through grooves 6, so that the bamboo flute tube material is heated more evenly. During the heating process, the operator holds the bamboo flute tube material and moves it back and forth and rotates. The temperature of the electric heating wire 5 is maintained between 700 - 800 degrees to ensure that the tube material can be heated evenly. After the bamboo flute tube material is heated and softened, it is then straightened by a straightening machine for subsequent straightening processing. This heating device uses the electric heating wire 5 for heating, with uniform heating, which can improve the straightening degree and utilization rate of the bamboo flute tube material. Compared with traditional heating devices, it can also reduce environmental pollution. Embodiment 2

[0027] As Figure 3As shown, compared with Embodiment 1, the difference in Embodiment 2 is that a support rod 8 with adjustable length is fixedly provided on the support frame 2. The length direction of the support frame 2 intersects with the center line of the frame 3. A bracket 9 for supporting the bamboo flute blank is fixedly provided at the upper end of the support rod 8. The bracket 9 is a circular arc structure with an upward opening. When an operator holds the bamboo flute blank and extends it into the heating device, the bamboo flute blank can be placed on the bracket 9 for operation, which is more labor-saving. The height of the bracket 9 can be adjusted by adjusting the length of the support rod 8, and thus the position of the bracket 9 can be adjusted. The support rod 8 adopts an existing telescopic rod with adjustable length. When the bracket is not needed, the length of the support rod 8 can be shortened to lower the height of the bracket 9.
