Description

Technical Field

[0001] This utility model relates to the structure of a horizontal stretch box in the thin film production process, and in particular to a modular combined horizontal stretch box. Background Technology

[0002] With the rapid development of the electronics and information industry, the high integration, high density, and high speed of electronic devices cause circuits or chips to accumulate heat rapidly within a very small and limited space. The ability to dissipate heat in a timely manner has become crucial to the lifespan, operational stability, and safety performance of components. Polyimide (PI) film, with its excellent electrical properties, flame retardant properties, high temperature resistance, and radiation resistance, is widely used as a high-performance insulating material in the electronics and electrical fields, unmatched by other plastic films such as nylon film, polyester film, polypropylene film, and polyethylene film.

[0003] In the process of making PI film, the film needs to be subjected to more precise temperature control during the horizontal conveying process. In addition, depending on different needs, different forms of conveying and heating conditions are sometimes required during the horizontal conveying process. The existing horizontal conveying box has a simple structure and cannot meet the fine requirements of the product. Utility Model Content

[0004] The main purpose of this utility model is to provide a modular combination horizontal pull box to meet the requirements.

[0005] The technical means adopted by this utility model are as follows: a modular combined horizontal pull box, which is composed of horizontal pull box units that can be combined. The horizontal pull box unit is a ceramic heating subunit or a hot air heating subunit. There are two or more sets of horizontal pull box units, and the horizontal pull box unit includes at least one ceramic heating subunit and one hot air heating subunit.

[0006] The ceramic heating subunit is equipped with a thin film inlet and a thin film outlet. Multiple individually detachable temperature control modules are set between the thin film inlet and the thin film outlet. Each temperature control module is equipped with a temperature measuring device and a temperature control device. The temperature control modules are arranged side by side according to the direction of thin film travel.

[0007] The temperature control module consists of multiple individually detachable horizontal pull box ceramic temperature control units, each of which is equipped with a temperature measuring device and a temperature control device.

[0008] The ceramic temperature control unit of the horizontal pull box has a top plate and a bottom plate. Multiple heating blocks are set under the bottom plate. The heating blocks are arranged in a matrix. Each heating block is individually connected to a temperature control line, which is connected to a temperature control device. The heating blocks are ceramic heating blocks.

[0009] The base plate is a single piece of steel plate structure, and each heating block is set on the single piece of steel plate. There is a distance between the base plate and the top plate, and a heat insulation steel plate is set between the top plate and the base plate. The distance between the heat insulation steel plate and the top plate is greater than the distance between the heat insulation steel plate and the base plate.

[0010] A handle is installed on the top of the top panel.

[0011] The ceramic temperature control unit of the horizontal pull box is equipped with a rod-shaped temperature measuring device, whose probe passes through the top plate, the heat insulation steel plate and the bottom plate, and is located above the membrane.

[0012] The hot air heating subunit is also equipped with a film inlet and a film outlet, and includes an upper blowing platform and a lower blowing platform. A passage space is formed between the upper and lower blowing platforms, through which the film passes. The upper and lower blowing platforms are connected to a hot air supply section.

[0013] The upper and lower air blowing platforms are equipped with several air blowing toothed platforms corresponding to each other. The air blowing toothed platforms are provided with horizontal air outlet slits. The length of the air outlet slits matches the width of the membrane through which they pass. The width of each air blowing toothed platform is the same, and the width of the gap between the air blowing toothed platforms is also the same. Furthermore, the positions of the upper and lower air outlet slits are completely opposite.

[0014] The hot air supply section includes a fan. One end of the fan is connected to an electric heating device via a pipe, and the other end is connected to an upper and lower air blowing platform to supply hot air. The other end of the electric heating device connected to the fan is connected to a hot air recovery port via a pipe, which is located above the upper air blowing platform.

[0015] The beneficial effects of this utility model are as follows:

[0016] The design of the ceramic heating subunit makes the entire equipment modular and zoned, with temperature measuring and control devices in each zone. This allows for more accurate temperature measurement of the corresponding area and precise local temperature adjustment based on different temperatures, which is more conducive to the quality control of the finished film and improves product quality and yield.

[0017] The hot air heating subunit is designed to simultaneously blow hot air onto the top and bottom of the film during film transport to control its temperature. Furthermore, the controlled airflow also provides support for the transported film. The circulating structure of the hot air supply section allows for the recycling of hot air, resulting in greater energy efficiency, reduced power consumption, and improved economic benefits.

[0018] The modular design allows for the free combination of different forms of horizontal pull box structures. In particular, it can flexibly utilize the respective advantages of the ceramic heating subunit and the hot air heating subunit to meet different film conveying needs, thus greatly improving the flexibility and convenience of production.

[0027] This utility model provides a modular combined horizontal pull box, such as Figures 1A-1C As shown, it is composed of configurable horizontally stretched box units Z connected together. Each horizontally stretched box unit Z is divided into a ceramic heating subunit 1 or a hot air heating subunit 1A. There are two or more sets of horizontally stretched box units Z, and each horizontally stretched box unit Z contains at least one ceramic heating subunit 1 and one hot air heating subunit 1A. The combination method can be arbitrarily set according to requirements. This utility model provides three forms. The key is that there is at least one ceramic heating subunit and one hot air heating subunit, and they are connected end to end, with the film stretched horizontally through them.

[0028] like Figures 2-6 As shown, the ceramic heating subunit 1 is provided with a thin film inlet 11 and a thin film outlet 12. The thin film enters from the thin film inlet 11 and exits from the thin film outlet 12. One or more ceramic heating subunits 1 can be provided as needed. In this embodiment, two sets are shown in the accompanying drawings (the hot air heating subunits are not shown; this is a description of the present invention). Figures 1A-1CAs shown, this must be combined with a hot air heating subunit, and they are connected end to end. Multiple individually detachable temperature control modules 13 are arranged between the film inlet 11 and the film outlet 12. Each temperature control module 13 is equipped with a temperature measuring device and a temperature control device, and the temperature control modules 13 are arranged side-by-side according to the film's travel direction. Here, there are two or more temperature control modules 13; in this preferred embodiment, there are six. Each temperature control module 13 is equipped with a temperature measuring device and a temperature control device, which allows for more accurate measurement of the temperature in the corresponding area and enables fine-tuning of the temperature locally, which is more conducive to the quality control of the finished film, improving product quality and yield.

[0029] And, as Figure 4 As shown, the temperature control module 13 consists of multiple individually detachable horizontal pull box ceramic temperature control units 14, each equipped with a temperature measuring device and a temperature control device. In this preferred embodiment, each temperature control module 13 consists of three horizontal pull box ceramic temperature control units 14, each capable of independent temperature measuring and control, further refining the temperature adjustment function. Furthermore, this modular design allows for the repair or replacement of only one horizontal pull box ceramic temperature control unit when it malfunctions, significantly improving production efficiency.

[0030] In this embodiment, as Figure 6 As shown, multiple heating blocks 141 are arranged below the ceramic temperature control unit 14 of the horizontal pull box. These heating blocks 141 are generally ceramic heating blocks, and they are arranged in a matrix, with two columns of 10 blocks each in the attached diagram of this embodiment. The number of blocks can be increased or decreased as needed. Figure 4 As shown, each heating block 141 is individually connected to a temperature control line 142, which is connected to a temperature control device (not shown in the figure), so that the heating capacity of each heating block 141 can be adjusted by the temperature control device to achieve further precise temperature control.

[0031] like Figure 5 As shown, each heating block 141 is mounted on a base plate 143. This base plate 143 is spaced a distance from the top plate 10 of the horizontal pull-box ceramic temperature control unit 14, ensuring that the high internal temperature does not affect the upper part of the unit. A heat-insulating steel plate 144 is also installed between the top plate 10 and the base plate 143 of the horizontal pull-box ceramic temperature control unit 14. The distance between the heat-insulating steel plate 144 and the top plate 10 of the horizontal pull-box ceramic temperature control unit 14 is greater than the distance between the heat-insulating steel plate 144 and the base plate 143. The heat-insulating steel plate allows heat to be better retained within the horizontal pull-box ceramic temperature control unit. The base plate can also be a single steel plate structure.

[0032] like Figure 3As shown, in this embodiment, a rod-shaped temperature measuring device is provided, with its probe 51 passing through the top plate 10, heat-insulating steel plate 144, and bottom plate 143 of the horizontal pull box ceramic temperature control unit, positioned above the film. This allows for more accurate temperature measurement.

[0033] Furthermore, a handle 15 can be installed above the top plate 10 as needed, which can be used to facilitate the lifting of the entire ceramic temperature control unit of the horizontal pull box for maintenance or replacement.

[0034] Please see Figure 7 and Figure 8 As shown, the hot air heating subunit 1A of this utility model is also provided with a film inlet 11 and a film outlet 12. It includes an upper blowing platform 1' and a lower blowing platform 2', with a passage space 3' formed between the upper and lower blowing platforms, through which the film passes; the upper and lower blowing platforms are connected to a hot air supply section 4'. The overall design concept is to simultaneously blow hot air onto the film from both above and below during the film conveying process to control the temperature. In addition, the airflow control can also support the film during conveying.

[0035] In this embodiment, the upper blowing platform 1' and the lower blowing platform 2' are provided with several blowing toothed platforms 5' corresponding to each other, and the blowing toothed platforms 5' are provided with transverse air outlet slits 6'. The length of the air outlet slit matches the width of the film through which it passes. This allows for more uniform and comprehensive heating and blowing of the film, as well as support of the film.

[0036] Ideally, all the blower teeth should have the same width, and the gaps between them should also be the same width. This ensures more uniform airflow, and the upper and lower air outlet positions are perfectly aligned. The blower teeth can be set very closely together; the density and number of teeth can be set according to requirements, which can be chosen by those skilled in the art.

[0037] In addition, the hot air supply section 4' includes a fan 41'. One end of the fan 41' is connected to an electric heating device 42' via a pipe, and the other end is connected to the upper air blowing platform 1' and the lower air blowing platform 2' to supply hot air. The other end of the electric heating device 42' connected to the fan 41' is connected to a hot air recovery port 43' via a pipe. This hot air recovery port 43' is located above the upper air blowing platform 1'. Since hot air generally flows upward, this arrangement is more conducive to hot air recovery. Utilizing this circulation structure allows for the recycling of hot air, making it more energy-efficient and environmentally friendly, reducing power consumption, and improving economic benefits.

[0038] This utility model adopts a modular design, which can freely combine different forms of horizontal pull box structures. In particular, it can flexibly utilize the respective advantages of the ceramic heating subunit and the hot air heating subunit to meet different film conveying needs and fully improve the flexibility and convenience of production.
