[0015] The preferred embodiments of the present application will be described in detail below with reference to the drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art, and the protection scope of the present application can be more clearly defined.

[0016] Please refer to Figure 1 and Figure 2 , the present application embodiment comprises:

[0017] A sizing device for continuous fiber prepreg production includes: a mounting base 1, a sizing bracket 8, a sizing die 2, a heating jacket 3, and a heat insulation mechanism. The mounting base 1 is made of 3030 type aluminum alloy profile with a track structure on its surface. The sizing bracket 8 is fixed on the mounting base 1. The sizing bracket 8 is generally L-shaped and consists of a base plate 803, a grid heat dissipation plate 802, and a sizing die mounting plate 801. The base plate 803 is the short side of the L-shape. Two bolt mounting holes are arranged along the center line of the base plate 803. Fastening bolts 10 can pass through the bolt mounting holes to move the sizing bracket 8 along the track structure on the mounting base 1. The grid heat dissipation plate 802 and the sizing die mounting plate 801 are fixed together to form the long side of the L-shape, wherein the grid heat dissipation plate 802 is vertically fixed to the base plate 803, and the sizing die mounting plate 801 is located on top of the grid heat dissipation plate 802; the heat insulation mechanism includes a cooling fan 6 and a fan frame 7, the fan frame 7 is installed on the side of the grid heat dissipation plate 802 away from the base plate 803, the cooling fan 6 is installed on the fan frame 7, and the air outlet direction is directly towards the grid heat dissipation plate 802; the sizing die 2 is installed inside the heating sleeve 3, and the heating sleeve 3 is fixed to the sizing die mounting plate 801.

[0018] The heating jacket 3 is equipped with a heating rod 5 and a temperature sensor 4. The heating rod 5 is located on the side of the heating jacket 3 closer to the heat insulation mechanism, and the temperature sensor 4 is installed on the side of the heating jacket 3 away from the heat insulation mechanism. This design ensures that heat is drawn from bottom to top when the heating jacket 3 is heated, making the temperature sensor 4 more accurate in detecting the temperature. Otherwise, if the heating rod 5 were placed on top, the heating jacket 3 would be affected by the heat insulation mechanism below, resulting in a large temperature gradient and distorting the readings of the temperature sensor 4.

[0019] The sizing die mounting plate 801 is provided with a sizing die fixing position, which includes two bolt fixing holes 804 symmetrical about the centerline of the sizing die mounting plate. The mounting surface of the heating sleeve is provided with two corresponding threaded holes. The distance between the two bolt fixing holes 804 is the same as the distance between the two threaded holes. A wire routing clearance opening 805 is provided on the plate surface between the two bolt fixing holes 804. The two bolt fixing holes 804 are longitudinal elongated holes. After installation, the inner side of the heating sleeve 3 is tightly fitted to the sizing die mounting plate 801, resulting in good overall stability. Furthermore, the wire inlet height of the sizing die 2 can be finely adjusted according to actual needs.

[0020] The heat dissipation fins 9 are mounted on the side of the grid heat dissipation plate 802 away from the heat insulation mechanism in a grid structure. The width of the grid heat dissipation plate 802 is not greater than the mounting width of the fan frame 7. The heat dissipation fins 9 can significantly improve the heat dissipation efficiency, and the purpose of the width of the grid heat dissipation plate 807 being not greater than the mounting width of the fan frame 7 is to reduce the possibility of heat affecting the lower bracket through the periphery of the grid and improve the overall effect of the cooling fan 6.

[0021] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made by using the content of the present application specification and drawings, is also included in the patent protection range of the present application.
