Description

Technical Field

[0001] The utility model belongs to the technical field of release film curing devices, and particularly relates to a thermal curing device for processing release films. Background Technique

[0002] As a key auxiliary material in the hot pressing process, release films are widely used in industries such as automobile manufacturing and electronic products. During the hot pressing process, the release film plays a role in preventing the material to be processed from adhering to the surface of the mold, thereby protecting the mold surface and ensuring the quality and appearance of the product. When processing release films, thermal curing is required. However, existing thermal curing devices have certain defects when curing release films. For example, in a Chinese patent with the publication number "CN 209577268 U", a thermal curing device for processing release films is disclosed, which includes a curing box body. The top end of the side of the curing box body is provided with a feeding pipeline, and a first curing mechanism and a second curing mechanism are installed inside the curing box body; the structures of the first curing mechanism and the second curing mechanism are the same, and the first curing mechanism and the second curing mechanism are arranged vertically offset; guide wheels are distributed around the first curing mechanism and the second curing mechanism, and a release film is connected between the guide wheels; the bottom end of the other side of the curing box body is provided with a discharging pipeline; the first curing mechanism includes an outer filter screen, the outer filter screen is fixed inside the curing box body, and an electric heating wire is arranged inside the outer filter screen; a rotating shaft is arranged inside the electric heating wire, and blades are fixed on the outer side of the rotating shaft; the end of the rotating shaft is connected to a motor, and the rotating shaft is connected to the second curing mechanism through a belt. When this device cures the release film, most of the hot air generated by the device will be directly discharged to the outside of the device, so there will be a large amount of heat loss, which not only reduces the thermal curing efficiency of the release film but also increases the use cost of the device. Moreover, when the device guides the hot air flow to blow on the release film, it is easy for more dust to adhere to the release film, increasing the subsequent processing steps and processing difficulty.

[0026] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-7 as shown, the present utility model provides the following technical solutions:

[0028] A thermal curing device for release film processing, including a housing member. A conveying channel for horizontally conveying the release film along a preset path is formed inside the housing member, and two air guiding members 6 are installed on the housing member. The air guiding member 6 includes a hot air guiding unit and a heat exchange tube 61. A first air conveying channel for conveying hot air flow along a preset path to the inside of the conveying channel is formed on the hot air guiding unit. A second air conveying channel for conveying the gas inside the conveying channel along a preset path to the outside of the housing member is formed on the heat exchange tube 61. The outlet ends of the two first air conveying channels are respectively located above and below the release film.

[0029] A heat exchange member is sleeved between some of the heat exchange tubes 61 and the first air conveying channel. A third conveying channel for conveying air is formed inside the heat exchange member. The air inside the third conveying channel exchanges heat with the gas inside the heat exchange tube 61, and the outlet end of the third air conveying channel is communicated with the inlet end of the first air conveying channel.

[0030] Through the above technical solutions, when the device needs to thermally cure the release film, the release film is input from the feeding end of the conveying channel on the housing and discharged from the discharging end of the conveying channel. When the release film is moving, through the operation of the air guiding member 6, the hot air guiding unit guides the hot air flow to move, so that the hot air flow flows along the first conveying channel until the hot air flow is conveyed to the inside of the conveying channel, thereby thermally curing the release film. When the hot air flow thermally cures the release film, through the guidance of the heat exchange tube 61, the hot air inside the conveying channel is conveyed to the inside of the heat exchange tube 61. When the hot air flow flows inside the heat exchange tube 61, through the operation of the heat exchange member, the outside air is guided to flow, and then heat exchange is carried out with the hot air flow inside the heat exchange tube 61 and the temperature rises. After the air temperature rises, the hot air is conveyed back to the first air conveying channel through the third conveying channel, thereby recycling the hot air, reducing the use cost, and improving the thermal curing efficiency.

[0031] Specifically, in one embodiment, regarding the above housing member:

[0032] Such as Figures 1-4 and Figure 6As shown, the housing part includes a housing 1, on which two material guiding holes 4 are horizontally formed. The release film moves between the two material guiding holes 4, and a driving part for driving the movement of the release film is installed inside the housing 1.

[0033] In this embodiment, the release film is input through the material guiding hole 4 on one side of the housing 1 and discharged through the material guiding hole 4 on the other side of the housing 1. By the operation of the driving part, the release film is driven to move between the two material guiding holes 4, which is convenient for receiving heat curing by hot air flow.

[0034] In addition, in the present utility model, regarding the above-mentioned driving part:

[0035] As Figure 6 shown, the driving part includes two symmetrically arranged driving rollers 9. The release film moves between the two driving rollers 9, and the driving rollers 9 are located between the two material guiding holes 4.

[0036] A motor 5 is fixedly connected to the outside of the housing 1, and the output end of the motor 5 is connected to the driving roller 9.

[0037] In this embodiment, when the release film moves between the two material guiding holes 4, by the operation of the motor 5, the driving roller 9 rotates inside the housing 1, and the release film is driven to move inside the housing 1 by the driving roller 9.

[0038] When the release film moves, in order to make the movement of the release film smoother, as Figures 1-4 shown, two mounting brackets 3 are fixedly connected to both symmetric sides of the housing 1. The material guiding hole 4 is located between the two mounting brackets 3, and a material guiding roller 2 is rotatably connected to the mounting bracket 3.

[0039] In this embodiment, when the release film moves, the housing 1 supports the mounting bracket 3, the mounting bracket 3 supports the material guiding roller 2, and the material guiding roller 2 assists the movement of the release film, making the movement of the release film smoother and improving the heat curing efficiency of the release film.

[0040] Specifically, in another embodiment, regarding the above-mentioned hot air guiding unit:

[0041] As Figures 1-3 、 Figures 5-7 shown, the hot air guiding unit includes a second air inlet pipe 67, a second air inlet fan 610 is installed inside the second air inlet pipe 67, and the air outlet end of the second air inlet pipe 67 is fixedly connected to an air outlet pipe 68. The air outlet end of the air outlet pipe 68 is fixedly connected to an air outlet hood 66. One side of the air outlet hood 66 extends into the housing 1, and a guide air shell 7 is fixedly connected to the side of the air outlet hood 66 extending into the housing 1. An air outlet hole 11 is formed on the side of the guide air shell 7 facing the release film, and a plurality of electric heating rods 10 are fixedly connected to the inside of the guide air shell 7.

[0042] In this embodiment, when it is necessary to guide hot air to thermally cure the release film, the second intake fan 610 operates to guide external air into the interior of the second intake pipe 67. The air flow is guided through the outlet pipe 68, so that the hot air is transported into the interior of the air outlet cover 66. The air is guided through the air outlet cover 66 into the interior of the air guide housing 7. The air is heated by the electric heating rod 10 and the hot air is discharged through the air outlet holes 11, thereby thermally curing the release film.

[0043] When the device recovers hot air, in order to improve the recovery rate of hot air, as Figure 6 shown, a rubber film 8 is fixedly connected inside the housing 1. A gap for the release film to pass through is formed on each of the two rubber films 8, and the air guide housing 7 is located between the two rubber films 8.

[0044] In addition, in the present utility model, regarding how the heat exchange member operates, as Figures 1-3 、 Figures 5-7 shown, the heat exchange member includes a gas guide box 62. The gas guide box 62 is sleeved on the heat exchange pipe 61, and a first intake pipe 65 is fixedly connected to the top of the gas guide box 62. A first intake fan 69 is installed inside the first intake pipe 65, and the bottom of the gas guide box 62 communicates with the interior of the second intake pipe 67.

[0045] In this embodiment, when the space between the two rubber films 8 is filled with hot air, the hot air is received by the heat exchange pipe 61. When the hot air flows inside the heat exchange pipe 61, the first intake fan 69 inside the first intake pipe 65 operates to guide external gas into the interior of the first intake pipe 65. The gas is transported through the first intake pipe 65 into the interior of the gas guide box 62, so that the hot air inside the heat exchange pipe 61 exchanges heat with the hot air. After the air temperature rises, the hot air is transported into the interior of the second intake pipe 67, thereby recycling the hot air, reducing the use cost, and improving the thermal curing efficiency of the release film.

[0046] When the device guides the air flow, in order to prevent dust from entering the interior of the device, as Figures 1-3 、 Figure 5 and Figure 7 shown, a first filter plate 63 is fixedly connected to the intake side of the first intake pipe 65, and a second filter plate 612 is fixedly connected to the intake side of the second intake pipe 67.

[0047] In this embodiment, when the first intake pipe 65 and the second intake pipe 67 inhale gas, the gas is filtered by the first filter plate 63 and the second filter plate 612 respectively to prevent dust from entering the interior of the device.

[0048] In addition, in the present utility model, in order to facilitate the cleaning of the first filter plate 63 and the second filter plate 612, as Figures 1-3 、 Figure 5 、 Figure 7As shown, a first scraping plate 64 for scraping the air intake side of the first filter plate 63 is rotatably connected to one side of the first filter plate 63, and one side of the first scraping plate 64 is connected to the axis of the first air intake fan 69. A second scraping plate 611 for scraping the air intake side of the second filter plate 612 is rotatably connected to one side of the second filter plate 612, and one side of the second scraping plate 611 is connected to the axis of the second air intake fan 610.

[0049] In this embodiment, when the first filter plate 63 and the second filter plate 612 filter the gas, the first scraping plate 64 and the second scraping plate 611 are respectively driven to rotate by the first air intake fan 69 and the second air intake fan 610. When the first filter plate 63 and the second filter plate 612 filter the gas respectively, the first filter plate 63 and the second filter plate 612 can be scraped synchronously, so that the device can continuously suck the gas into the device.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
