[0023] See also Figure 1 -6, the present invention is a precise temperature-controlled polyimide film imidization horizontal pull box structure, which includes a horizontal pull box unit 1, and the horizontal pull box unit 1 is provided with a film inlet 11 and a film outlet 12, and the film enters from the film inlet 11 and exits from the film outlet 12. The horizontal pull box unit 1 can be provided with one or more as needed. In the attached figure of this embodiment, two groups are provided, and they are arranged end to end, which is only for illustration. A plurality of independently detachable temperature control and heating modules 13 are provided between the film inlet 11 and the film outlet 12, and each temperature control and heating module 13 is provided with a temperature measuring device and a temperature control device. Each temperature control and heating module 13 can be arranged in parallel or staggered according to the direction of film travel. There are more than two temperature control and heating modules 13 here, and in this optimal embodiment, one horizontal pull unit includes 6 temperature control and heating modules. Each temperature control and heating module 13 is provided with a temperature measuring device and a temperature control device, so that the temperature of the corresponding area can be measured more accurately, and local fine temperature adjustment can be performed according to the different temperatures, which is more conducive to the quality control of the finished film and improves product quality and product yield.

[0024] And, if Figure 3 As shown, the temperature control and heating module 13 is also composed of a plurality of independently detachable temperature control modules 14, each of which is provided with a temperature measuring device and a temperature control device. In the best embodiment, each temperature control and heating module 13 is composed of three temperature control modules 14, each of which can measure and control temperature independently, further refining the temperature adjustment function. In addition, by adopting this modular design, when the temperature control and heating module 14 fails, only the temperature control and heating module 14 needs to be repaired or replaced, which significantly improves the production efficiency.

[0025] In this embodiment, if Figure 5 As shown, a plurality of heating blocks 141 are disposed below the temperature control module 14. The heating blocks 141 are generally far-infrared ceramic heating plates. The heating blocks 141 are arranged in a matrix form, such as Figure 4 As shown, each heating block 141 is connected to a temperature control circuit 142, and the temperature control circuit 142 is connected to a temperature control device (not shown in the figure), so that each heating block 141 can adjust the heating capacity through the temperature control device to achieve further precise temperature control.

[0026] like Figure 4As shown, each heating block 141 is arranged on a whole mounting steel plate 143, and there is a distance between the mounting steel plate 143 and the top of the temperature control module 14, so that although the internal temperature is high, it will not affect the upper part, and a heat insulation board 144 is also arranged between the top of the temperature control module 14 and the mounting steel plate 143, and the distance between the heat insulation board 144 and the top of the temperature control module 14 is greater than the distance between the heat insulation board 144 and the mounting steel plate 143. The heat insulation board allows the heat to be better preserved in the temperature control module.

[0027] As shown in the figure, in this embodiment, the temperature measuring device is a temperature sensor 5, whose probe 51 passes through the top of the temperature control module, the insulation board 144 and the mounting steel plate 143, and is located above the film to measure the temperature more accurately.

[0028] In addition, if Figure 2 As shown, in order to make the temperature control and heating module 13 have better insulation and heating effects, according to the principle of heat radiation, a side steel plate 4 is installed inside the side wall of each temperature control and heating module 13, and the side steel plate 4 is a detachable structure. With the support of the side steel plates on the left and right sides, the heat can be better maintained in the film position, so that the insulation and heating effects of the entire horizontal pull box are better, and energy can be saved, which meets the needs of energy conservation and emission reduction.

[0029] like Figure 6 As shown, the top of the edge steel plate 4 is an acute angle bending groove 41, and the top of the temperature control module 14 is provided with a reverse bending groove 42 corresponding to the acute angle bending groove 41. The acute angle bending groove 41 and the reverse bending groove 42 are hooked with each other, so that the edge steel plate 4 is suspended and fixed. This case adopts the most simplified design, which makes the installation and removal of the steel plate very convenient, and is also easy to repair and replace without adding extra costs.

[0030] In addition, a number of side operating doors 3 are provided on at least one side of the horizontal pull box unit 1. The side operating doors are mainly used for conventional operations such as clamping, tensioning or rolling the internal film. When operating, please note that the side steel plates 4 at the corresponding positions must be removed. Therefore, the side steel plates are designed to be a simple structure as described above for easy operation. A transparent observation window may be fixedly provided on the side operating door 3 to facilitate observation of the internal process conditions during operation. The design of multiple side operating doors also facilitates rapid cooling after shutdown. By adopting a multi-temperature control heating module, the overall height of the box is greatly reduced. Due to the setting of edge insulation measures, such as edge steel plates or independently set edge heating devices, the side operating door has limited access methods and space, and cannot fully assume the function of an inspection door. For this reason, please refer to Figure 7As shown, a transverse pull box unit adopts a temperature-controlled heating module composed of a far-infrared ceramic heating plate, and a plurality of bottom inspection openings 6 are opened on the bottom plate of the transverse pull box unit 1. The inspection openings 6 are provided with bottom inspection doors 2 that can be opened and sealed. A pulley 8 or a slide rail is arranged under the transverse pull box unit 1 to prevent the box body from expanding and deforming.

[0031] In addition, if Figure 7 As shown, wind curtains 7 are provided at the inlet and outlet of the horizontal pull box unit 1, and the wind curtain 7 has a first exhaust part 71 and a second exhaust part 72 arranged opposite to each other, and at least one flow equalizing plate is provided in the first exhaust part 71 and / or the second exhaust part 72, and a channel space 73 is formed between the first exhaust part 71 and the second exhaust part 72, and the width of the channel space 73 is adapted to the width of the film, and the flow equalizing plate is provided with a plurality of wind holes or a plurality of slit holes.
