Description

Technical Field

[0001] The utility model relates to the technical field of coating machine equipment, in particular to a coating machine oven distributed heating device. Background Art

[0002] The main function of a coater is to coat a layer of coating, adhesive or ink with specific functions on a rolled substrate such as paper, plastic film and other materials, and solidify the coating through a drying process, and finally roll up or cut the treated substrate into sheets. The oven of the coater is a key part of the coater. Its function is to remove the solvent or moisture in the coating by heating, ensuring that the coating can dry quickly and achieve the expected performance. However, the existing coater oven heating device usually uses steam heating and hot air heating when drying the cloth, and this heating method is prone to uneven heating.

[0003] In order to address the above problems, the Chinese patent with the existing announcement number CN220697351U proposes a distributed heating device for a coating machine oven. The device drives the heating roller to be in close contact with the cloth through a cylinder, and at the same time, the heating tube heats the heating roller. As the cloth is transmitted, the heating roller in contact with the cloth dries both sides of the cloth.

[0004] However, although the above-mentioned distributed heating device of the coating machine oven can achieve drying of the cloth by fitting the heating roller and the cloth so that the heating tube heats the heating roller, when the heating tube continues to heat the heating roller, the heat on the heating roller will continue to accumulate, so that the cloth is easily burned when the heating roller directly contacts the cloth for drying. Therefore, the utility model provides a distributed heating device of the coating machine oven to meet the demand. Utility Model Content

[0028] like Figures 1 to 6As shown, an embodiment of the utility model provides a distributed heating device for a coating machine oven, comprising a base 1, a box body 2 is provided on the top, an inlet 14 and an outlet 13 are penetrated at the front and rear ends of the box body 2, an insulation box 3 is arranged on the side of the box body 2, a heating pipe 15 is provided in the insulation box 3, a plurality of air ducts 9 are symmetrically provided along the inlet 14 inside the box body 2, the plurality of air ducts 9 are arranged along the length direction of the box body 2, the plurality of air ducts 9 are connected to the insulation box 3, a plurality of exhaust holes 18 are penetrated along the length direction of the air duct 9, an exhaust fan mechanism 10 is provided at the end of the insulation box 3 away from the air duct 9, the exhaust fan mechanism 10 is driven by a motor 11, and a through hole 16 is penetrated between the insulation box 3 and the exhaust fan mechanism 10.

[0029] Specifically, the heating of the heating tube 15 is controlled by an external setting, and at the same time, the driving motor 11 drives the exhaust fan mechanism 10 to convey airflow into the insulation box 3, so that the airflow conveys the hot air generated by the heating tube 15 to the air guide tube 9 and is discharged to the cloth along the exhaust hole, thereby improving the drying effect of the cloth and avoiding the cloth from being scalded. This solves the problem that when the heating tube 15 of the existing coating machine oven distributed heating device continues to heat the heating roller, the heat will continue to accumulate on the heating roller, thereby making it easy for the cloth to be scalded when the heating roller is in direct contact with the cloth for drying.

[0030] like Figure 4 As shown, in this embodiment, the heating tube 15 is fixed in the heat preservation box 3 in a serpentine structure along the length direction of the box body 2.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, a connecting pipe 8 is connected between the heat preservation box 3 and the exhaust fan mechanism 10, and the connecting pipe 8 is a funnel-shaped structure.

[0032] like Figure 5 and Figure 6As shown, in the present embodiment, a guide plate 17 is fixedly connected in the air guide tube 9, one end of the guide plate 17 is fixedly connected to the inner bottom wall of the air guide tube 9, and the other end is suspended in the air guide tube 9, the guide plate 17 divides the air guide tube 9 into two mutually connected first cavity 22 and second cavity 21, the exhaust hole 18 is located in the first cavity 22, and a plurality of exhaust holes 19 are penetrated on the air guide tube 9 of the second cavity 21, the diameter of the exhaust hole 18 is smaller than the diameter of the exhaust hole 2 19, and a guide plate 20 with an arc-shaped structure is fixedly connected in the second cavity 21. Specifically, when the wind flow enters the first cavity 22 in the air guide tube 9, part of the wind flow will be discharged to the exhaust hole 1, however, due to the small diameter of the exhaust hole 1, most of the air flow is discharged to the second cavity 21, and is discharged to the exhaust hole 2 under the action of the guide plate and the guide plate 20, so that the hot air discharged from the exhaust hole 1 and the exhaust hole 2 can be more uniform, so that the cloth can be fully and evenly dried, thereby improving the drying effect of the cloth.

[0033] like Figures 1 to 3 As shown, in the present embodiment, a first guide mechanism 6 and a second guide mechanism 7 are fixedly connected on the base 1 adjacent to the inlet 14 and the outlet 13, and the first guide mechanism 6 and the second guide mechanism 7 have the same mechanism, and the second guide mechanism 7 includes two support plates 73 relatively arranged on the base 1 and two transmission rollers 71 connected to the support plates 73 for relative rotation through a rotating shaft 72, and gears 5 are sleeved on the two rotating shafts 72 of the second guide mechanism 7, and the two gears 5 are meshed with each other, and one of the rotating shafts 72 of the second guide mechanism 7 is connected to the driving shaft of the motor 11 through a belt transmission mechanism 4, specifically, the transmission of the second guide mechanism 7 is realized while the exhaust fan mechanism 10 is driven to rotate by the motor 11, and the overall linkage is high.

[0034] Working principle:

[0035] The cloth is sequentially passed through the first guide mechanism 6, the inlet 14, the box 2, the outlet 13, and the second guide mechanism 7, so that the cloth is located between the two transmission rollers 71 and between the oppositely arranged air guide tubes 9, and the exhaust fan mechanism 10 is driven to rotate by the motor 11, so that the motor 11 drives the rotating shaft 72 to rotate through the belt transmission mechanism 4, and the rotating shaft 72 drives the two mutually meshing gears 5 to rotate, so that the two transmission rollers 71 on the second guide mechanism 7 drive the cloth to move, and at the same time, by heating the heating tube 15, the wind flow discharged by the exhaust fan mechanism 10 will heat the heat generated by the heating tube 15. The air is discharged into the air guide tube 9, wherein a part of the airflow is discharged toward the cloth along the exhaust hole 1, and the other part is discharged to the second cavity 21 under the action of the guide plate 17, and is discharged along the exhaust hole 2 under the action of the guide plate 20, so that the exhaust hole 1 and the exhaust hole 2 can discharge the hot air flow evenly, thereby improving the uniformity of drying the cloth and avoiding the cloth from being scalded. This solves the problem that when the heating tube 15 of the existing coating machine oven distributed heating device continues to heat the heating roller, the heat will continue to accumulate on the heating roller, thereby making it easy for the cloth to be scalded when the heating roller is in direct contact with the cloth for drying.
