Description

Technical Field

[0001] The utility model relates to the technical field of coating drying, in particular to a heating auxiliary device for a coating machine. Background Technique

[0002] During the coating process, it is necessary to heat the coating material to ensure the uniformity and adhesion of the coating. In the prior art, most coating machines are heated by gas, but there is a lack of an auxiliary device to filter the gas entering the coating area for heating, resulting in the fact that in some occasions with strict coating quality requirements, such as semiconductor manufacturing or the application of precision coatings, the heating gas usually contains dust particles, oil stains, moisture and other impurities. If these impurities adhere to the coating material, coating defects will be caused.

[0003] Therefore, in order to solve the defect that the coating quality is reduced due to impurities in the heating gas, it is very necessary to propose a heating auxiliary device for a coating machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heating auxiliary device for a coating machine, which can filter the heating gas through a filtering mechanism to prevent impurities contained in the gas from adhering to the coating material and improve the coating quality, so as to solve the problems raised in the above background technique.

[0007] The filtering mechanism includes symmetrically arranged filter cylinders. A gas guide pipe is connected up and down between the filter cylinders. An air inlet is opened in the middle of the upper gas guide pipe, and an air outlet is opened in the middle of the lower gas guide pipe. Butterfly valves are symmetrically installed at positions on both sides of the air inlet or the air outlet of the gas guide pipe. A connecting pipe is welded between the upper and lower butterfly valves;

[0008] One end of the hose is hermetically connected to the air outlet, and the other end is hermetically connected to the drying tube.

[0009] Preferably, air nozzles are equidistantly installed on the lower surface of the drying tube.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. For the heating auxiliary device of this coater, by introducing a filtering mechanism to assist during the heating of the coater, it can effectively remove dust particles, oil stains, moisture and other impurities in the heating gas, thereby preventing these impurities from adhering to the coating material, significantly improving the coating uniformity and adhesion, and reducing the occurrence of coating defects;

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. 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 creative efforts shall fall within the protection scope of the present utility model.

[0023] To solve the technical problem of how the device heats the coating, please refer to Figure 1 - Figure 2, this embodiment provides the following technical solutions:

[0024] A heating auxiliary device for a coater, comprising a heating mechanism 1, a filtering mechanism 2 assisting the heating mechanism 1, and a hose 3. A drying pipe 11 is fixedly installed in the heating mechanism 1, and air nozzles 12 are equidistantly installed on the lower surface of the drying pipe 11.

[0025] The filtering mechanism 2 includes symmetrically arranged filter cartridges 21. A gas guide pipe 22 is connected up and down between the filter cartridges 21. An air inlet 23 is opened in the middle of the upper gas guide pipe 22. A hot air blower is hermetically connected outside the air inlet 23. An air outlet 24 is opened in the middle of the lower gas guide pipe 22.

[0026] One end of the hose 3 is hermetically connected to the air outlet 24, and the other end is hermetically connected to the drying pipe 11.

[0027] Specifically, the hot air blower introduces hot air into the filtering mechanism 2 from the air inlet 23. The hot air will enter the filter cartridge 21 along the gas guide pipe 22. After being filtered by the filter element 212, the hot air is discharged from the air outlet 24, then enters the drying pipe 11 along the hose 3, and finally is sprayed out from the air nozzle 12 to realize the heating of the coating.

[0028] To solve the technical problem of how the device realizes continuous heating, please refer to Figure 3 - Figure 4 , this embodiment provides the following technical solutions:

[0029] The top of the filter cartridge 21 is detachably connected with a cover 211. A filter element 212 is fixedly installed on the lower surface of the cover 211. A handle 213 is fixedly installed on the upper surface of the cover 211.

[0030] Butterfly valves 25 are symmetrically installed at positions on both sides of the air inlet 23 or the air outlet 24 of the gas guide pipe 22. A valve plate 251 is rotatably arranged in the butterfly valve 25. A connecting pipe 26 is welded between the upper and lower butterfly valves 25. A rotating rod 261 is rotatably arranged in the connecting pipe 26. The rotating rod 261 is fixedly connected with the valve plate 251. The top of the rotating rod 261 penetrates through the gas guide pipe 22 and is connected with a rotating handle 262.

[0031] Specifically, when it is necessary to clean the filter element 212, rotate the rotating handle 262 near the filter element 212. The rotating handle 262 drives the valve plate 251 to rotate through the rotating rod 261, so that the valve plate 251 seals the gas guide pipe 22. The hot air cannot enter this filter cartridge 21 from the gas guide pipe 22 and can only enter the other filter cartridge 21 for filtration, preventing the interruption of the filtration of the hot air when the filter element 212 is replaced and realizing the continuous filtration of the hot air;

[0032] The steps for replacing the filter element 212 are as follows: Remove the bolts at the upper end of the filter cartridge 21 to separate the cover 211 from the filter cartridge 21. Then, pull the cover 211 upward through the handle 213. The cover 211 drives the filter element 212 to move upward until the filter element 212 is removed from the filter cartridge 21. Then, clean the filter element 212. After cleaning, reinsert the filter element 212 into the filter cartridge 21 for installation.

[0033] Working principle: When this coating machine heating auxiliary device is in use, the hot air blower introduces hot air into the filtering mechanism 2. The hot air enters the filter cartridge 21 along the air duct 22. After being filtered by the filter element 212, it is discharged from the air outlet 24, and then is introduced into the drying pipe 11 along the hose 3 and finally sprayed out from the air nozzle 12 to achieve heating of the coating. When it is necessary to clean the filter element 212, first close the butterfly valve 25 near the filter cartridge 21 to prevent the hot air from entering the filter cartridge 21 through the air duct 22. Then, remove the bolts at the upper end of the filter cartridge 21 to separate the cover 211 from the filter cartridge 21. Lift the cover 211 upward through the handle 213. The cover 211 drives the filter element 212 to move upward until the filter element 212 is removed from the filter cartridge 21. Clean the filter element 212. After cleaning, reinsert it into the filter cartridge 21 for installation. During this process, the hot air will enter another filter cartridge 21 along the air duct 22 for filtering to achieve the continuity of hot air filtering.
