[0022] The purpose of the present invention is to provide a continuous transmission molding device for hard carbon fiber thermal insulation materials to solve the problems existing in the prior art, make the hard carbon fiber spiral winding molding process simple to operate, reduce costs, and improve production efficiency and product quality.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3 As shown: This embodiment provides a continuous transmission molding device for hard carbon fiber thermal insulation materials, including a frame 1 and a raw material shaft 9, a conveyor belt 12, a positioning roller 4, a molding mold 3, an extrusion shaft 6 and a motor 5 arranged on the frame 1, the motor 5 is connected to the rotating shaft 2 of the molding mold 3, the conveyor belt 12 is wound around the positioning roller 4 and the molding mold 3, and the conveyor belt 12 bypasses an extrusion shaft 6 when entering and winding out of the molding mold 3, one end of the raw material belt is wound around the raw material shaft 9, and the other end of the raw material belt is arranged on the molding mold 3, and the raw material belt is attached to the conveyor belt 12 and enters the molding mold 3.

[0025] A tension adjustment mechanism for the conveyor belt 12 is provided on the frame 1, and the tension adjustment mechanism is in contact with the conveyor belt 12 and can adjust the tension of the conveyor belt 12. The tension adjustment mechanism includes a lifting component 7 and an adjustment roller 8. The adjustment roller 8 is provided on the top of the lifting component 7, and the adjustment roller 8 is in contact with the inner ring of the conveyor belt 12. The lifting component 7 is a hydraulic cylinder or an electric push rod, and the lifting component 7 is connected to the frame 1 through a pin shaft, which is convenient for adjusting the tension of the conveyor belt 12. The power of the conveyor belt 12 comes from the friction generated by the recovery and rotation of the auxiliary material belt.

[0026] The forming mold 3 is a spiral winding forming mold. The forming mold 3 is cylindrical, and a mounting hole for the rotating shaft 2 is provided in the center. The forming mold 3 is detachable, and has different sizes according to different product specifications. The extrusion shaft 6 is a pressure shaft, and a pressurizer is provided on the pressure shaft. The center angle between the two extrusion shafts 6 and the axis of the forming mold 3 is less than 90°. In this embodiment, according to different product requirements, it is necessary to select raw material strips (length, width, weight) of different specifications, auxiliary material strips (length, width) and different pressures to carry out the product forming process.

[0027] A plurality of positioning rollers 4 are located around the raw material shaft 9, and the raw material shaft 9 is located in the loop of the transmission belt 12. The motor 5 is connected to the raw material shaft 9 through a sprocket and chain or a pulley and a synchronous belt.

[0028] The specific use process of the continuous transmission molding equipment for hard carbon fiber thermal insulation materials in this embodiment is as follows:

[0029] First, the raw material belt is wound onto the raw material shaft 9 for standby use, and the raw material belt is pulled out from the raw material shaft 9 and laid flat on the conveyor belt 12 and connected to the forming mold 3. The motor 5 is started, and the motor 5 drives the forming mold 3 to rotate slowly. As the forming mold 3 rotates, the raw material belt is continuously wound into the forming mold 3. At the same time, the extension length of the lifting component 7 is adjusted according to the product state, and the tension of the conveyor belt 12 is increased to apply pressure to the raw material belt until the raw material belt is used up and fixed to the outermost layer of the forming mold 3. The motor 5 is turned off, and the conveyor belt is removed. The blank 11 is fixed in the forming mold 3 with the external fixing device 10. The forming mold 3 is removed and transported to the oven, and the temperature is increased to solidify the product, and the mold is removed. The width of the raw material belt determines the height of the blank 11 product. The width of the booster conveyor belt must be greater than the width of the raw material. The inner diameter of the blank 11 depends on the outer diameter of the forming mold 3. The outer diameter of the blank 11 depends on the length of the raw material belt. The longer the length, the more windings, and the thicker the wall thickness. The appropriate raw material length will be calculated in advance based on the product wall. The relationship between the formed product and the forming mold 3 is as follows: Figure 3 As shown, when the product reaches the required size of the blank 11, the blank 11 can be subsequently processed.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
