[0002] Polyetheretherketone (PEEK) is a polymer consisting of a repeating unit containing a ketone group and two ether bonds in the main chain structure. It is a semi-crystalline plastic and a special polymer material with the advantages of high strength, high wear resistance and high thermal stability. Since PEEK is almost insoluble in organic solvents, it is first necessary to modify PEEK to break the regularity of the molecular chain, and then dissolve it in the solvent to form a solution, and then pass the fiber bundle or fabric through the resin matrix solution at a certain speed to make it soaked with a certain amount of resin matrix, and finally dry it.

[0003] A Chinese patent with publication number CN115183561B discloses a vertical drying device and implementation method for composite sheets for PEEK sheet prepreg. The surface humidity of the composite sheet is sensed by a monitoring device, and the angle of a movable induced draft box is adjusted according to the humidity. The movable induced draft box discharges hot air, and the discharge position is adapted to the position of the composite sheet to be dried. The movable induced draft box is accurately adjusted according to the specific position, which can effectively reduce the use time of the energy-saving drying box and save the power consumption of the energy-saving drying box.

[0024] In order to solve the problem that the prepreg drying process is inefficient and the heat from the drying process easily diffuses to the external environment, causing heat waste and indirectly increasing energy consumption, please refer to Figure 1-3The utility model provides an embodiment: a high-efficiency heat-insulating drying device for processing PEEK sheet prepreg, comprising a mounting frame 1 and a prepreg tape 3, and also comprising a heating plate 2, the mounting frame 1 being a hollow rectangular frame structure, the heating plate 2 being mounted inside the mounting frame 1, a heat-insulating plate 101 being arranged on the surface of the mounting frame 1, a plurality of reinforcing ribs being arranged on the long side of the mounting frame 1 parallel to the ground, the reinforcing ribs being welded to the mounting frame 1, a connecting block 102 being arranged on the surface of the reinforcing ribs, a limiting plate 4 being arranged inside the mounting frame 1, the limiting plate 4 being connected to the mounting frame 1 by screws, a first roller 401 and a second roller 402 being arranged on the side of the limiting plate 4, an exhaust channel 6 being arranged above the mounting frame 1, an exhaust port being arranged on the bottom surface of the exhaust channel 6, the exhaust port being communicated with the interior of the mounting frame 1, an exhaust fan 601 being arranged inside the exhaust channel 6, and a tensioning mechanism 5 being arranged on the side of the heating plate 2.

[0025] A plurality of electric heating tubes are arranged inside the heating plate 2. The heating plate 2 is divided into three layers, upper, middle and lower. Each layer is composed of at least three heating plates 2. A limiting plate 4 is arranged between every two layers of heating plates 2. One end of the connecting block 102 is connected to the heating plate 2 by screws, and the other end of the connecting block 102 is welded to the mounting frame 1. The connecting block 102 limits the relative position between the heating plate 2 and the mounting frame 1. The limiting plate 4 is divided into two layers, upper and lower. Two limiting plates 4 placed opposite to each other form one layer. The first roller 401 is installed between the two limiting plates on the upper layer. The second roller 402 is installed in the middle of the two limiting plates 4 in the lower layer; the prepreg tape 3 shuttles up and down between the first roller 401, and the first roller 401 is in the middle of the two layers of heating plates 2. The two layers of heating plates 2 heat the prepreg tape 3 and the surrounding air at the same time, and the volatiles inside the prepreg tape 3 are mixed with the hot air and sent out of the mounting frame 1 by the exhaust fan 601, avoiding the situation where the heat of the upper and lower prepreg tape 3 is uneven and the drying degree is different, thereby further improving the efficiency of the prepreg drying process.

[0026] A prepreg inlet and outlet channel is arranged at one end of the heat insulation board 101 on the upper surface of the mounting frame 1, and a rectangular through hole 103 is arranged on the surface of the heat insulation board 101 in contact with the tensioning mechanism 5, and the rest of the surface of the mounting frame 1 is wrapped by the heat insulation board 101, thereby reducing the heat loss inside the mounting frame 1, and further reducing the energy consumption required to generate heat.

[0028] Working principle: A heat insulation plate 101 is arranged on the surface of the mounting frame 1, and three layers of heating plates 2 are arranged inside the mounting frame 1. A limiting plate 4 is arranged between every two layers of heating plates 2, and a roller is arranged between the opposite limiting plates 4.

The prepreg tape 3 enters the interior of the mounting frame 1 from the outside, first passes through the upper roller, then passes through the tensioning mechanism 5, and then passes through the lower roller, and finally leaves the mounting frame 1. The heating plate 2 continuously heats the air inside the mounting frame 1, and the volatiles inside the prepreg tape 3 are mixed with the hot air and sent out of the mounting frame 1 by the exhaust fan 601.
