[0002] A conductive film is a thin film material with conductive function, usually composed of conductive materials (such as metals, carbon nanotubes, graphene, etc.) and a substrate. The conductive film has good electrical conductivity and flexibility, and can be widely used in various electronic devices, such as touch screens, solar cells, flexible electronics, etc.

[0003] During the production of conductive films, a calender is usually required; before calendering, the raw materials usually need to be heated.

[0004] Currently, in related technologies, a heating device includes: a dielectric tube and a heating electric tube. The heating electric tube is installed inside the dielectric tube. When heating, the heating electric tube is started to heat the inside of the dielectric tube; then, the raw materials are introduced into the dielectric tube to heat the raw materials.

[0005] However, after long-term use, the surface of the heating electric tube located inside is prone to aging, and even explosion may occur, with relatively high danger. Utility Model Content

DETAILED DESCRIPTION

[0035] The present application provides a raw material heating device for producing a conductive film.

[0036] Embodiment 1:

[0037] See also Figure 1 , Figure 2 and Figure 3 A raw material heating device for producing a conductive film comprises: a heating tube 1 and an electric heating tube 2. The electric heating tube 2 is wound around the outer wall of the heating tube 1, and a plurality of electric heating tubes 2 are evenly distributed along the axial direction of the heating tube 1. When heating, the electric heating tube 2 is started to heat the inside of the heating tube 1, and then the raw materials for producing the conductive film are introduced to heat the raw materials; and the electric heating tube 2 does not directly contact the raw materials inside, thereby slowing down the aging speed of the electric heating tube 2 to improve the safety of the electric heating tube 2 when in use.

[0038] See also Figure 1 A high temperature resistant cloth 21 is provided on the outer wall of the heating tube 1, and the high temperature resistant cloth 21 wraps the electric heating tube 2. The high temperature resistant cloth 21 can make it less likely for the electric heating tube 2 to produce sparks after long-term use, thereby further improving the safety of the electric heating tube 2 when in use.

[0039] See also Figure 1 Furthermore, a temperature measuring tube 11 is connected to the heating tube 1, and a temperature measuring device 12 is arranged in the temperature measuring tube 11. In the embodiment of the present application, the temperature measuring device 12 can adopt a PT100 temperature sensor, an acid-resistant and alkali-resistant thermocouple and a high-temperature resistant temperature measuring probe. The temperature measuring device 12 can detect the temperature of the raw material in the heating tube 1 and adjust the heating efficiency of the electric heating tube 2 according to the detection value to reduce the possibility of dangerous phenomena.

[0040] The working principle of the first embodiment of the present application is as follows: when heating, the electric heating tube 2 is started to heat the inside of the heating tube 1, and then the raw materials for producing the conductive film are introduced to heat the raw materials; and the electric heating tube 2 is not in direct contact with the internal raw materials, thereby slowing down the aging speed of the electric heating tube 2, so as to improve the safety of the electric heating tube 2 when in use.

[0041] Embodiment 2:

[0042] See also Figure 4, Figure 5 and Figure 6 , the difference between this embodiment and the first embodiment is that both ends of the heating tube 1 in the length direction are fixedly sleeved with sleeve plates 3, and a sealing component is arranged between the two sleeve plates 3. When the environmental humidity is high, the sealing component can seal the high-temperature resistant cloth 21, thereby reducing the contact with water vapor, so that the high-temperature resistant cloth 21 is not easily damp, and thus the electric heating tube 2 is not easily aged too fast. The sealing component includes: a measuring part 8, a sealing part 4, a pulling part 6 and a reset part 5.

[0043] See Figure 4 , the measuring part 8 includes: a humidity sensor 81 with high temperature resistance, and the humidity sensor 81 is installed on the side wall of any sleeve plate 3. The temperature sensor can monitor the environmental humidity in real time and feedback it to the controller to determine whether it is necessary to seal the high-temperature resistant cloth 21.

[0044] See Figure 5 , the sealing part 4 includes: a receiving rod 41, a sliding rod 42 and a high-temperature resistant film 43. Ring grooves 31 are opened on the opposite sides of the two sleeve plates 3. One end of the receiving rod 41 is fixed in one of the ring grooves 31 and the other end is fixed in the other ring groove 31. One end of the sliding rod 42 is arranged in one of the ring grooves 31 and the other end is arranged in the other ring groove 31; the high-temperature resistant film 43 is fixed between the reset part 5 and the sliding rod 42. In the embodiment of the present application, the high-temperature resistant film 43 can adopt a polyimide film. When it is detected that the environmental humidity is high, the sliding rod 42 is driven to move in the ring groove 31 to pull the high-temperature resistant film 43 to be unfolded, so as to seal the high-temperature resistant cloth 21.

[0045] See Figure 6 , further, a placement groove 421 is opened on the end wall of the sliding rod 42, and a ball 9 is arranged in the placement groove 421. The ball 9 abuts against the bottom of the ring groove 31, and the ball 9 can reduce the friction force received when the sliding rod 42 moves.

[0046] See Figure 4 and Figure 6 , the pulling part 6 includes: a pulling rod 61, a pulling rope 62 and a driving motor 63. An installation groove 411 is opened on the side wall of the receiving rod 41 along the length direction, and the pulling rod 61 is rotatably installed in the installation groove 411 and is horizontally arranged. One end of the pulling rope 62 is fixedly connected to the pulling rod 61, and the other end is wound around the ring groove 31 and is fixedly connected to the sliding rod 42. The driving motor 63 is installed on any sleeve plate 3, and the output shaft of the driving motor 63 is coaxially fixed to the pulling rod 61. When it is detected that the environmental humidity is high, the driving motor 63 is started to drive the pulling rod 61 to rotate, so as to wind up the pulling rope 62; during the winding process, the pulling rope 62 pulls the sliding rod 42 to move in the ring groove 31, so as to unfold the high-temperature resistant film 43 to seal the high-temperature resistant cloth 21.

[0047] See Figure 6 Figure 6 , the reset part 5 includes a reset rod 51 and a coil spring 52. On the side of the receiving rod 41 away from the placement groove 411 and along the length direction, a receiving groove 412 is formed, and a receiving hole 413 is formed on the inner wall of the receiving groove 412; the reset rod 51 is arranged in the receiving groove 412, and the end of the reset rod 51 is rotatably installed in the receiving hole 413, and one end of the high-temperature resistant film 43 away from the sliding rod 42 is wound around the reset rod 51.

[0048] See Figure 6 Figure 6 , the coil spring 52 is sleeved on one end of the reset rod 51 located in the receiving hole 413, one end is fixed to the reset rod 51, and the other end is fixed to the inner wall of the receiving hole 413. When it is necessary to recycle the high-temperature resistant film 43, the driving motor 63 is started to drive the pulling rod 61 to reverse; at this time, the coil spring 52 restores its deformation to drive the reset rod 51 to rotate, thereby winding the high-temperature resistant film 43.

[0049] The working principle of the second embodiment is as follows: when it is detected that the environmental humidity is relatively high, the driving motor 63 is started to drive the pulling rod 61 to rotate, thereby winding the pulling rope 62; during the winding process, the pulling rope 62 pulls the sliding rod 42 to move in the annular groove 31, thereby unfolding the high-temperature resistant film 43 to cover the high-temperature resistant cloth 21.

[0050] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
