Description

Technical Field

[0001] The utility model relates to the technical field of PVC film production equipment, in particular to a glue coating and curing device for antistatic PVC film production. Background Art

[0002] Polyvinyl chloride (PVC) film is a material widely used in a variety of applications. Its characteristics include good chemical stability, low cost and excellent processing performance. PVC film has been widely used in packaging, construction, electronics and medical industries due to its water resistance, corrosion resistance and electrical insulation. Especially in the electronics industry, antistatic PVC film becomes particularly important because the presence of static electricity may cause damage to sensitive electronic components. Antistatic PVC film effectively reduces or eliminates the effects of static electricity accumulation by adding antistatic agents to the PVC substrate to change its surface resistance, providing protection for static sensitive equipment. In addition, these films are also used to manufacture curtains and partitions in clean rooms to prevent dust and other particles from polluting the environment due to static electricity attraction, ensuring high cleanliness production conditions.

[0003] In the process of producing antistatic PVC film, uniformly coating the antistatic agent on the PVC film and curing it is one of the key steps. Although the traditional hot air curing method is widely used to cure the coating, this method has some limitations in the production of antistatic PVC film. For example, the high-temperature airflow during hot air blowing may cause uneven surface temperature of the film, affecting the curing effect of the antistatic agent, resulting in unstable antistatic properties of the film. In addition, the hot air flow may cause vibration or displacement of the film, further affecting the uniformity and overall quality of the coating. In the field of electronic and medical device packaging, this quality fluctuation is unacceptable because it is directly related to the safety and reliability of the product. Therefore, it has become an urgent need for the industry to develop a new curing equipment that can provide a more uniform and controllable curing process to optimize the production of antistatic PVC film.

For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0032] See also Figure 1-7 As shown, the utility model provides a technical solution of a glue curing device for antistatic PVC film production: a glue curing device for antistatic PVC film production, comprising a frame 1, a hot air generator 2 is arranged on the side of the frame 1, a gas diverter 3 is connected to the side of the hot air generator 2, and a hot air mechanism 4 and a hot roller mechanism 5 are respectively arranged on the side of the gas diverter 3;

[0033] The hot air mechanism 4 includes a first hot air pipe 401, a corner portion 402, and an upper spoiler 403. One end of the first hot air pipe 401 is connected to the air outlet end of the gas diverter 3, and the other end of the first hot air pipe 401 is connected to the frame 1. The corner portion 402 is arranged at the connection between the frame 1 and the first hot air pipe 401. The upper spoiler 403 is arranged inside the frame 1. The lower spoiler 404 is symmetrically arranged on the side of the upper spoiler 403. The blocking end of the lower spoiler 404 is parallel to the discharge end of the upper spoiler 403. Before the glue is cured, The interior of the frame 1 is preheated by the hot air generator 2. During this process, part of the hot air will enter the interior of the frame 1 under the guidance of the gas diverter 3, the first hot air pipe 401 and the corner portion 402. When the hot air blows to the upper spoiler 403, it will be guided again to be blown to the lower spoiler 404, and finally discharged through the discharge end of the lower spoiler 404. On the one hand, a certain turbulence is achieved, so that the heat inside the frame 1 can be more uniform. On the other hand, a relatively smooth airflow can be blown to the surface of the film, thereby achieving the effect of improving the curing of the film coating.

[0034] The hot roller mechanism 5 includes a second hot air pipe 501 and a hot roller 503. The second hot air pipe 501 is connected to the air outlet end of the gas diverter 3. A plurality of through holes 502 are provided on the side of the second hot air pipe 501. Both sides of the hot roller 503 are rotatably connected to the frame 1 through the through holes 502. The inside of the frame 1 can be preheated by the hot air generator 2 before the glue is cured. During this process, part of the hot air will enter the inside of the second hot air pipe 501 under the guidance of the gas diverter 3. Since the second hot air pipe 501 has few corners and most of it is located inside the frame 1, the heat loss during the transmission process is low, which accelerates the heating speed of the hot roller 503. On the other hand, this heating can ensure that the film glue curing can be preheated and gradually heated up to improve the curing effect.

[0035] The upper spoiler 403 and the lower spoiler 404 are both crescent-shaped. This design can effectively guide the airflow path and help form a smooth airflow, thereby achieving more stable and uniform airflow coverage on the film surface, ensuring uniform solidification of the film coating.

[0036] The interior of the hot roller 503 is a hollow structure. In the specific implementation process, the hot roller 503 can be a hollow aluminum roller. This design allows the hot roller 503 to quickly respond to temperature changes in the heating system, ensuring that the hot roller 503 can reach the required heating temperature in a shorter time. At the same time, it can also provide more uniform heat distribution and improve the film curing effect.

[0037] The upper spoiler 403 is arranged in a sequence that gradually approaches the inner surface of the frame 1 along the flow direction of the hot air. This design helps to evenly disperse the hot air and improves the utilization efficiency of the hot air in the curing machine.

[0038] A guide column 6 is arranged inside the frame 1, and the guide column 6 can guide the film when it enters or leaves the frame 1, ensuring that the film moves along a predetermined trajectory, so that the film can continuously and smoothly pass through the curing processing area during the production process, thereby improving the operation efficiency of the entire production line.

[0039] The working principle of the utility model is as follows:

[0040] The gluing and curing device for producing antistatic PVC film of the present embodiment can preheat the interior of the frame 1 through the hot air generator 2 when in use. During this process, a part of the hot air will be sent into the frame 1 through the first hot air pipe 401 for internal heating, and a part of the hot air will heat the hot roller 503 through the second hot air pipe 501. Inside the frame 1, the upper spoiler 403 and the lower spoiler 404 assist in improving the direction and distribution of the hot air flow, so that the hot air blown to the film is smoother, thereby improving the flatness of the coating, and the preheated hot roller 503 can preheat the film in advance, avoiding damage to the physical properties of the film or uneven coating quality due to sudden temperature changes, thereby improving the performance quality of the final product.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
