Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically a coating bridge drying mechanism. Background Technology

[0002] After the plastic film is coated, it needs to be dried using drying equipment to accelerate the evaporation of the solvent or water coated on the plastic film, ensuring that the coating is dry and firmly adheres to the film surface, and preventing the coating from peeling off or bubbling.

[0003] In related technologies, a PET film drying device (publication number CN221365471U) was found to have a scheme in which a large amount of hot air continuously accumulates in the arc-shaped cavity structure formed by the side cavity and the deposition cavity when hot air is introduced. The heat is continuously conducted outward through the surface of the side cavity and the deposition cavity, and is transferred to the edge and middle of the PET film respectively. Combined with the hot air flow from the edge of the film to the middle, the PET film is dried in two forms: hot air and heat radiation. This fully utilizes the heat carried by the hot air flow, accelerates the drying process, and saves drying time and equipment operating costs.

[0004] However, in the above scheme, hot air will diffuse into the air, resulting in a large waste of heat energy. It is also inconvenient to control the stability of the temperature, and the temperature range of the hot air fluctuates greatly. When the air temperature is high, the leaked hot air can easily cause burns to the operators. Utility Model Content

[0005] The purpose of this invention is to provide a coating bridge drying mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating bridge drying mechanism, including a coating machine, on which two heat insulation covers are installed, and infrared heating lamps are installed in the heat insulation covers. The heat insulation covers can prevent contact with the infrared heating lamps and ensure that there will be no burns.

[0007] The insulated box is located on the side of the coating machine. A fan unit is installed on the upper surface of the insulated box. A heater is installed inside the lower part of the insulated box and is connected to the fan unit. Several exhaust pipes are installed on the heater. The insulated box realizes internal circulation heating, with small temperature fluctuations, which can better dry the plastic film.

[0008] The support frame consists of two units installed on the left and right sides of the insulation box. A handle bolt is screwed onto the upper part of the support frame, and a baffle is slidably connected to the lower part of the support frame. The baffle is rotatably connected to the handle bolt. The two baffles are located below the inlet and outlet of the insulation box. The baffles can block the inlet and outlet, reduce the leakage of hot air, and prevent the problem of hot air burns.

[0009] Furthermore, the heat insulation cover is fitted with support plates at both ends, and the support plates are fixedly connected to the coating machine. The heat insulation cover is screwed with handle nuts at both ends to abut the support plates. When arranging the plastic film, the heat insulation cover can be rotated to make room for arranging the plastic film, making the operation more convenient.

[0010] Furthermore, the fan unit includes a centrifugal fan and an exhaust pipe connected to the centrifugal fan. The exhaust pipe is connected to the insulation box, and the exhaust pipe is connected to the heater. The upper surface of the insulation box is provided with a collection hopper, and the exhaust pipe is connected to the collection hopper, which can better collect the rising hot air and facilitate stable hot air circulation.

[0011] Furthermore, a cooling fan is installed on the side of the insulated box, and the air outlet of the cooling fan is connected to a nozzle assembly. A small portion of the leaked hot air is mixed with the air blown by the cooling fan, reducing the air temperature and ensuring that there will be no burns.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) When drying plastic film in the heat preservation box, turn the handle bolt to control the baffle to move down and block the inlet and outlet of the heat preservation box, reduce the leakage of hot air, effectively alleviate the problem of burns, and the cooling fan cools the leaked hot air through the nozzle group to ensure that the temperature of the air leaking from the heat preservation box is not too high and prevent burns.

[0014] (2) The upper and lower infrared heating lamps preheat the plastic film, so that the coated material is pre-fixed onto the plastic film. The infrared heating lamps have an arc-shaped heat insulation cover, so there will be no burn problem. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a coating bridge drying mechanism, including a coating machine 1, on which two heat insulation covers 2 are installed, and infrared heating lamps 15 are installed in the heat insulation covers 2. The infrared heating lamps 15 heat the freshly coated plastic film, so that the coating material and the plastic film are pre-fixed, which is convenient for subsequent drying in the middle of the heat preservation box 4.

[0023] The insulated box 4 has two sealed doors. Opening the sealed doors makes it easy to wrap the plastic film around the roller 14, making the operation convenient and quick.

[0024] The insulation box 4 is located on the side of the coating machine 1. A fan unit is installed on the upper surface of the insulation box 4. A heater 12 is provided inside the lower part of the insulation box 4 and is connected to the fan unit. Several exhaust pipes 13 are installed on the heater 12. The fan unit works with the heater 12 to circulate heat in the insulation box 4. The internal circulation heating system can effectively reduce the diffusion of heat energy to the external environment, thereby improving the utilization rate of heat energy and reducing energy consumption. The internal circulation heating system can achieve the required heating effect more quickly, thereby improving production efficiency.

[0025] The bracket 9 is provided in two parts and installed on the left and right sides of the heat preservation box 4. The upper part of the bracket 9 is screwed with a handle bolt 18, and the lower part of the bracket 9 is slidably connected with a baffle 19. The baffle 19 is rotatably connected to the handle bolt 18. The two baffles 19 are located below the inlet and outlet of the heat preservation box 4. Turning the handle bolt 18 up and down can move the baffles 19 up and down, which can block the inlet and outlet of the heat preservation box 4 and ensure that the baffles 19 do not come into contact with the plastic film, thereby reducing the leakage of hot air.

[0026] In this embodiment, as Figure 1 As shown, the heat insulation cover 2 is fitted with support plates 16 at both ends. The support plates 16 are fixedly connected to the coating machine 1. The heat insulation cover 2 is screwed with handle nuts 17 that abut against the support plates 16 at both ends. Loosening the handle nuts 17 allows the heat insulation cover 2 and the infrared heating lamps 15 to rotate. When the plastic film passes between the two infrared heating lamps 15, the operating space is larger, making it easier to introduce the plastic film from the coating machine 1 into the heat preservation box 4.

[0027] In this embodiment, as Figure 2 As shown, the heat preservation box 4 is equipped with several rollers 14, which are arranged in a staggered manner, so that the plastic film is arranged in a more tortuous way inside the heat preservation box 4, which can extend the heating time of the plastic film, increase the heating area, and improve the drying effect.

[0028] In this embodiment, as Figure 2 As shown, the fan unit includes a centrifugal fan 7 and an exhaust pipe group 6 connected to the centrifugal fan 7 and an exhaust pipe 8. The exhaust pipe group 6 is connected to the insulation box 4, and the exhaust pipe 8 is connected to the heater 12. The upper surface of the insulation box 4 is provided with a collection hopper 5. The exhaust pipe group 6 is connected to the collection hopper 5. The collection hopper 5 can extract hot air over a larger area, which can accelerate air circulation, increase the heating speed, and make the temperature inside the insulation box 4 more uniform.

[0029] In this embodiment, as Figure 2 As shown, a cooling fan 11 is installed on the side of the insulated box 4. The air outlet of the cooling fan 11 is connected to a nozzle assembly 10. The cooling fan 11 draws in room temperature air and blows it onto the air leaking from the insulated box 4, ensuring that the leaked hot air will not burn the staff.

[0030] In this embodiment, as Figure 3 As shown, a lever 3 is fixedly connected to the surface of the heat insulation cover 2. When the handle nut 17 is tightened, the rotation resistance of the heat insulation cover 2 can be increased. At this time, it is more convenient to rotate the heat insulation cover 2 by using the lever 3.

[0031] Specifically, during use, the plastic film passes through the coating machine 1 and the insulation box 4. Tightening the handle bolt 18 controls the baffle 19 to block the inlet and outlet of the insulation box 4, ensuring that the baffle 19 does not contact the plastic film and limiting the leakage of hot air. After the coating machine 1 coats the plastic film, the infrared heating lamp 15 preheats the plastic film. The centrifugal fan 7 draws air from the insulation box 4 and sends it to the heater 12 for heating. The heater 12 blows the hot air onto the plastic film, such as... Figure 2 As shown, the exhaust pipe 13 on the left heats the inclined plastic film, causing the coating to be fixed onto the plastic film.

[0032] The cooling fan 11 blows air through the nozzle assembly 10 to the inlet and outlet of the insulation box 4. The small amount of hot air leaking out of the insulation box 4 is quickly cooled to room temperature, ensuring that there will be no burns.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
