[0021] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0022] As Figure 1As shown in the figure, the heating device for the drum 300 fixing machine includes a heating mounting base 200, which is located below the drum 300. An A0 heating unit 101 is provided on the heating mounting base 200. An A1 heating unit 102 and an A2 heating unit 103 are respectively arranged on the two outer sides of the A0 heating unit 101 along the A direction. The heating intensity of the A heating unit is greater than that of the A1 heating unit 102 and the A2 heating unit 103 respectively. The A direction is the horizontal radial direction of the drum 300. The distance between the A0 heating unit 101 and the outer wall surface of the drum 300 above it is denoted as L0. The distance between the A1 heating unit 102 and the outer wall surface of the drum 300 above it is denoted as L1. The distance between the A2 heating unit 103 and the outer wall surface of the drum 300 above it is denoted as L2. Both L1 and L2 are greater than L0.

[0023] The outer wall surface of the drum 300 is a cylindrical surface, and the distance between it and the heating device below shows a trend of being the smallest in the middle and gradually increasing towards the two outer sides. The heating of the upper drum 300 by the heating device below is mainly through heat conduction and heat radiation. When the distance is small, the heat radiation heating method dominates. After the distance increases to a certain extent, the heat radiation heating will be weakened, making heat conduction dominate. Since heat conduction mainly heats the air above the heating device and conducts the heat to the inner wall of the drum 300 through the air. Compared with the heat conduction heating method, the heat radiation heating method has a faster and better heating effect. In traditional heating devices, the heating intensity is the same everywhere. In this uniform distribution method, the heat radiation heating in the middle cannot be effectively exerted, and at the same time, the heating effect of heat conduction on the two outer sides is limited. Therefore, in the present utility model, compared with the traditional heating device, the heating intensity of the A0 heating unit 101 in the middle is increased, and the heating intensity of the A1 heating unit 102 and the A2 heating unit 103 on both sides is weakened. This strengthens the heat radiation heating method in the middle, significantly improves the heating effect, and at the same time, the heating effect on both sides does not change significantly, thus significantly enhancing the heating efficiency of the heating device and enabling the drum 300 to quickly heat up. There are many implementation methods to achieve the difference in heating intensity, such as using heating components with different powers to form different heating units respectively, and adjusting the distribution density of the heating components, etc.

[0024] A further solution is that the heating intensity of the A1 heating unit 102 is consistent with that of the A2 heating unit 103. Each heating component is arranged on the heating mounting base 200, and each heating component is used to form the A0 heating unit 101, the A1 heating unit 102, and the A2 heating unit 103. The heating component is composed of a heating resistance wire. Preferably, the heating resistance wire is a spiral heating resistance wire 100. A heating resistance body part 110 is arranged on the heating component. The length direction of the heating resistance body part 110 is consistent with the A direction. The heating resistance body parts 110 are arranged at intervals along the B direction. The B direction is a horizontal direction perpendicular to the A direction. The heating resistance body part 110 includes an A0 body part 111 and A1 body parts 112 and A2 body parts 113 on the outer sides of both ends of the A0 body part 111. The A0 body part 111 is used to form the A0 heating unit 101, and the A1 body parts 112 and A2 body parts 113 are respectively used to form the A1 heating unit 102 and the A2 heating unit 103. The heating intensities of the A1 body part 112 and the A2 body part 113 are both less than that of the A0 section. In this way, the A0 heating unit 101, the A1 heating unit 102, and the A2 heating unit 103 with different heating intensities can be reliably formed.

[0025] During specific implementation, the heating resistance wire can be bent and wound around the heating mounting base 200 in a meandering shape, such as S-shaped or M-shaped installation. A more preferred method is that the spiral heating resistance wire 100 is composed of two heating resistance body parts 110, and the two heating resistance body parts 110 are arranged in a U shape. The two ends of the spiral heating resistance wire 100 are respectively electrically connected to the neutral wire and the live wire. Specifically, different body part resistances can be achieved by adjusting the pitch between the spiral resistance wires, and thus different heating intensities can be achieved. More specifically, the pitch of the resistance wire of the A0 body part 111 is denoted as d0, the pitch of the resistance wire of the A1 body part 112 is denoted as d1, and the pitch of the resistance wire of the A2 body part 113 is denoted as d2. Both d1 and d2 are greater than d0. During the installation operation, two heating resistance body parts are formed on the spiral heating resistance wire 100, and then the resistance wire is stretched as required to form the A0 body part 111, the A1 body part 112, and the A2 body part 113 with different pitches. Then, each spiral heating resistance wire 100 is installed and assembled on the heating mounting base 200. The heating mounting base 200 can be implemented according to the existing implementation method of the heating mounting base 200.

[0026] In summary, the above solution provided by the present utility model can improve the heating efficiency and has a better heating effect on the drum 300 compared with the traditional heating device.

[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented by conventional means in the art without special instructions and limitations.
