Description

Technical Field

[0001] The utility model particularly relates to a film drying device and a film production system, and can be specifically applied to the field of film production equipment for tires and conveyor belts. Background Art

[0002] In the rubber industry, such as conveyor belts and tires, after the rubber film is produced, it needs to be dipped in an anti-sticking agent and then can be stored and transported. Since the anti-sticking agent is dissolved in water for dipping, the residual water on the film needs to be removed after dipping the anti-sticking agent. The existing technical solution is to transport the film dipped with the anti-sticking agent to a film drying rack and dry it with a fan at the film drying rack.

[0003] This traditional method is not only extremely likely to cause water stain residues in winter when the temperature is low, but also cannot completely drain the water in terms of time during continuous processing and production, resulting in quality hazards such as blisters and bulges in the subsequent process of molding and vulcanization. In addition, traditional solutions such as adding fans have high requirements for the production site and will increase the floor area problem. Summary of the Utility Model

[0006] Adopting the above technical solution, after the film is dipped with the anti-sticking agent in the anti-sticking agent tank, it enters the conveyor belt. There is a box body below the conveyor belt, a support belt is provided between the box body and the conveyor belt to support the conveyor belt, and a heating element is provided in the inner cavity of the box body. During the upward process of the conveyor belt transporting the film from the anti-sticking agent tank to the film drying rack, the heating element works to generate heat, and a heating space is formed between the inner cavity of the box body and the lower surface of the conveyor belt. The heating space is like an oven, and the heat generated by the heating element is quickly transmitted to the conveyor belt through the mesh-like hollow structure of the support belt, playing a transpiration role on the film on the conveyor belt, thereby reducing the water content on the film.

[0007] That is, this solution does not expand the scale of the film drying rack, does not increase the floor area, and has a reasonable structure, which can effectively remove the powder and water adhering to the film after cooling, improve the product quality, and reduce the risks of blistering and bulging during subsequent vulcanization production.

[0008] According to another specific embodiment of the present invention, the inner cavity and the lower surface of the conveyor belt define a heating space, and the temperature of the heating space is 55°C to 70°C.

[0009] Adopting the above technical solution, the temperature of the heating space is 55°C to 70°C, which has a drying effect while avoiding affecting the film quality due to too high temperature.

[0010] According to another specific embodiment of the present invention, the box body is made of stainless steel.

[0033] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the drawings.

[0034] Refer to Figure 1 , the embodiment of the present application provides a film production system 1, including: an anti-sticking agent tank 2, a film drying rack 3, a conveyor belt 5, and a film drying device 4; wherein, the anti-sticking agent tank 2 contains an anti-sticking agent, so that the rubber film is dip-coated with the anti-sticking agent in the anti-sticking agent tank 2, thereby forming a thin anti-sticking layer between the films, blocking or slowing down the mutual adhesion between the films, and thus facilitating the process operation.

[0035] The above-mentioned film drying rack 3 is equipped with a fan (not shown in the figure) to blow dry the film dip-coated with the anti-sticking agent to reduce the water adhering to the film surface.

[0036] And the above-mentioned conveyor belt 5 is used to transport the film from the anti-sticking agent tank 2 to the film drying rack 3, so that the film dip-coated with the anti-sticking agent enters the film drying rack 3 and is blown dry. Exemplarily, the conveyor belt 5 is a modular plastic conveyor belt.

[0037] The film drying device 4 is arranged below the conveyor belt 5 to dry the film in the process of being transferred on the conveyor belt 5. That is, the film drying device 4 and the film drying rack 3 cooperate to jointly achieve the water removal of the film.

[0038] The following will detail the specific structure of the film drying device 4 with reference to the drawings.

[0039] Reference Figures 1 to 4 , the film drying device 4 of the embodiment of the present application includes a box body 6, a support belt 7 and a heating element 8. Among them, the box body 6 is inclined upward along the first direction X. One end of the box body 6 in the first direction X is connected to the glue drying rack 3, and the other end is connected to the release agent tank 2. As Figure 3 shown, the box body 6 includes an inner cavity 60, and an opening 61 is provided at the upper end of the inner cavity 60. Exemplarily, the box body 6 is generally in the shape of a cuboid, and the first direction X is the length direction of the box body 6, and its periphery and bottom surface together enclose the inner cavity 60.

[0040] As Figure 3 and Figure 4 shown, the above-mentioned support belt 7 covers the opening 61 of the inner cavity 60, and the support belt 7 is a mesh-like hollow structure. Exemplarily, the support belt 7 supports the conveyor belt 5, and the inner cavity 60 and the lower surface of the conveyor belt 5 define a closed heating space.

[0041] As Figure 2 and Figure 5 shown, the heating element 8 is located inside the inner cavity 60. Exemplarily, the support belt 7 is a mesh-like hollow structure, so that the heat generated by the heating element 8 inside the inner cavity 60 can directly pass through the mesh-like hollow structure of the support belt 7 to the conveyor belt 5, playing a transpiration role on the film on the conveyor belt 5 to reduce the water attached to the surface of the film.

[0042] Exemplarily, there are multiple heating elements 8, and the multiple heating elements 8 are arranged at intervals inside the inner cavity 60. As Figure 5 shown, the multiple heating elements 8 are arranged in 2 rows and 45 columns, that is, there are 90 heating elements 8 in this embodiment. However, those skilled in the art can understand that in other embodiments, the multiple heating elements 8 can also be arranged in other arrangements, and the number of heating elements 8 can also be selected according to actual needs.

[0043] Exemplarily, the multiple heating elements 8 work to generate heat so that the temperature of the heating space is maintained at 55°C to 70°C. Optionally, the temperature of the heating space is 65°C, so as to be able to better dry the film on the conveyor belt 5 and achieve a better water removal effect. However, those skilled in the art can understand that in other embodiments, the temperature of the heating space can be other values, such as 55°C, 60°C, 70°C, etc., as long as the temperature is not too low or too high, because too low a temperature will result in poor drying effect, and too high a temperature will affect the film quality. For example, when the temperature of the heating space is less than 55°C, the film drying device 4 has a poor drying effect on the film, and the lower the temperature, the worse the drying effect on the film, and even there is no drying effect. Correspondingly, when the temperature of the heating space exceeds 70°C, it will affect the film quality, and the more the temperature exceeds 70°C, the greater the impact on the film quality, and even the film will be vulcanized.

[0044] Reference Figures 1 to 5 With the above technical solution, after the film is dip-coated with the release agent in the release agent tank 2, it enters the conveyor belt 5. There is a box body 6 below the conveyor belt 5, and a support belt 7 is provided between the box body 6 and the conveyor belt 5. The support belt 7 supports the conveyor belt 5, and a heating element 8 is provided in the inner cavity 60 of the box body 6. During the upward process of the conveyor belt 5 transporting the film from the release agent tank 2 to the film drying rack 3, the heating element 8 works to generate heat, and a heating space is formed between the inner cavity 60 of the box body 6 and the lower surface of the conveyor belt 5. The heating space is like an oven, and the heat generated by the working of the heating element 8 is quickly transmitted to the conveyor belt 5 through the mesh hollow structure of the support belt 7, which has a steaming effect on the film on the conveyor belt 5, thereby reducing the moisture content on the film.

[0045] After the film on the conveyor belt 5 reaches the film drying rack 3, the film is further dried by the fan equipped on the film drying rack 3 to further reduce the water adhering to the surface of the film.

[0046] In summary, this solution does not expand the scale of the film drying rack 3, does not increase the floor area, and has a reasonable structure. It can effectively remove the powder and water adhering to the film after cooling, improve the product quality, and reduce the risk of blistering and bulging during subsequent vulcanization production.

[0047] Reference Figure 3 In some possible implementation manners, the box body 6 is made of stainless steel. Exemplarily, the box body 6 is made of stainless steel to prevent the residual water stains on the film from flowing onto the box body 6 and causing rust on the box body 6.

[0048] Reference Figure 5 In some possible implementation manners, the heating element 8 is an electric heating tube 80. Exemplarily, taking the electric heating tube 80 as the heating element 8 in this embodiment, it has high efficiency, easy operation, and low cost.

[0049] In another implementation manner, the heating element 8 is an electric heating furnace (not shown in the figure). Exemplarily, an electric heating furnace refers to a device that uses electric energy to generate steam or hot water, and it has a simple structure, is light, clean and pollution-free, and has a high degree of automation.

[0050] Those skilled in the art can understand that the heating element 8 is not limited to the above-mentioned electric heating tube 80 and electric heating furnace. In other embodiments, other types of heating elements 8 can also be selected and placed in the inner cavity 60 of the box body 6 to achieve drying of the film.

[0051] Reference Figures 3 to 5, in some possible embodiments, the film drying device 4 further includes a power cord (not shown in the figure). A through hole 600 is provided on the cavity wall of the inner cavity 60. One end of the power cord is connected to the heating element 8, and the other end extends out of the inner cavity 60 from the through hole 600 to connect to an external power source. Those skilled in the art can understand that the way of connecting the heating element 8 to the power source is not limited to this type. For example, the power cord can also be selected at a suitable position on the support belt 7 to directly pass through the mesh-like hollow support belt 7 and connect to the power source.

[0052] Although the present invention has been illustrated and described by referring to some preferred embodiments of the present invention, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
