[0020] Please refer to Figure 1-6, the utility model discloses a precise temperature control chemical imidization polyimide film horizontal tension box structure, it contains horizontal tension box unit 1, this horizontal tension box unit 1 sets up film import 11 and film export 12, and the film is imported from film import 11, and the film is exported from film export 12. This horizontal tension box unit 1 can set up one or more according to the need, and two groups are set in the embodiment figure, and the head is connected to set. Multiple individually detachable temperature control modules 13 are arranged between film import 11 and film export 12, each temperature control module 13 is provided with temperature measuring device and temperature control device, and each temperature control module 13 is arranged in parallel according to the film advancing direction. The temperature control module 13 here is two or more, and it is six in the best embodiment. Each temperature control module 13 is provided with temperature measuring device and temperature control device, so that the temperature of the corresponding area can be measured more accurately, and local fine temperature adjustment can be carried out according to the temperature difference, which is more favorable for the quality control of film finished product, improves product quality and product yield.

[0021] And, as Figure 3 Shown, the temperature control module 13 also consists of multiple individually detachable temperature control modules 14, each temperature control module 14 is provided with temperature measuring device and temperature control device. In the best embodiment, each temperature control module 13 consists of three temperature control modules 14, and each temperature control module 14 can be individually temperatureed and temperature controlled, further refining the temperature adjustment function. In addition, using this modular design, when the temperature control module 14 fails, only the temperature control module can be repaired or replaced, which significantly improves production efficiency.

[0022] In the embodiment, as Figure 5 Shown, multiple heating blocks 141 are arranged below the temperature control module 14, the heating block 141 is generally a ceramic heating plate, and the heating block 141 is arranged in a matrix form, as Figure 4 Shown, each heating block 141 is individually connected with a temperature control line 142, and the temperature control line 142 is connected with a temperature control device (not shown in the figure), so that each heating block 141 can be adjusted by the temperature control device to realize further precise temperature control.

[0023] As Figure 4 Shown, each heating block 141 is arranged on an integral mounting steel plate 143, and the mounting steel plate 143 is spaced apart from the top of the temperature control module 14 by a distance, so that the internal temperature is high, but will not affect the upper part, and a heat insulation steel plate 144 is arranged between the top of the temperature control module 14 and the mounting steel plate 143, and the distance between the heat insulation steel plate 144 and the top of the temperature control module 14 is greater than the distance between the heat insulation steel plate 144 and the mounting steel plate 143. The heat insulation steel plate makes the heat better preserved in the temperature control module.

[0024] As shown in the figure, in this embodiment, the temperature measuring device is a rod-type temperature measuring device 5, whose probe 51 passes through the top of the temperature control module, the heat insulation steel plate 144 and the mounting steel plate 143, and is located above the film to measure the temperature more accurately.

[0025] In addition, if Figure 2 As shown, to ensure better insulation and heating performance for the temperature control modules 13, removable edge steel plates 4 are installed inside the side walls of each temperature control module 13 based on the principle of thermal radiation. Heat is retained within the film by the left and right edge steel plates, improving insulation and heating performance for the entire cross-tie box while also conserving energy and meeting energy conservation and emission reduction requirements.

[0026] like Figure 6 As shown, the edge steel plate 4 has an acute-angled bend groove 41 at the top, and the temperature control module 14 has a reverse-bend groove 42 at the top corresponding to the acute-angled bend groove 41. The acute-angled bend groove 41 and the reverse-bend groove 42 interlock with each other, thereby suspending the edge steel plate 4. This case adopts a minimalist design, making the steel plate very easy to install and remove, and also convenient for maintenance and replacement without adding additional costs.

[0027] In addition, several operating doors 3 are set on at least one side of the horizontal pull box unit 1. The operating doors are mainly used to facilitate routine operations such as tensioning or rolling the internal film. When operating, be careful to remove the edge steel plates 4 at the corresponding positions. Therefore, the edge steel plates are designed into the simple structure as described above for easy operation.
