Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a coating machine feeding device. Background Technology

[0002] A coating machine can coat a roll of substrate with a layer of adhesive, paint, or ink with specific functions, and then dry and rewind it. It uses a dedicated multi-functional coating head to achieve various forms of surface coating. Currently, before coating, the required paint must be poured into the coating machine's trough according to the product's processing requirements. Under the action of the coating roller, the paint is evenly coated onto the film, thus forming a coating layer.

[0003] The feeding device pumps materials from the processing tank into the trough. Due to the high viscosity of the coating, most processing tanks require a stirring mechanism. Traditional stirring methods mainly use a single stirring shaft and require rapid stirring. Because stable feeding is required, continuous stirring is necessary, and coating needs to be replenished to the processing tank periodically. Due to the large volume of the processing tank, when replenishing coating, the coating drips into the tank due to the drop, and combined with the stirring effect, easily generating air bubbles inside. Physical defoaming requires stopping the machine, affecting the stability of the coating supply. Therefore, real-time defoaming is necessary during the feeding process to meet the feeding requirements. Utility Model Content

[0021] As Figures 1-3 Indicated, a coating machine feed device, including multiple uniform settings single small processing tank, each single small processing tank is connected with liquid inlet assembly through liquid inlet pipe 10, and is connected with liquid supply assembly through liquid outlet pipe 11;The first electromagnetic valve 17 is arranged on the liquid inlet pipe 10 and the liquid outlet pipe 11;

[0022] The single small processing tank includes tank body 12, the coaxial fixed mounting of defoaming tank 13 is arranged in the tank body 12, the top opening of defoaming tank 13 is arranged, and the opening of defoaming tank 13 is lower than the top of tank 13, and the liquid outlet end of liquid inlet pipe 10 is located in defoaming tank 13;Stirring assembly is arranged in the defoaming tank 13, the sealing cover 14 is installed on the top of tank 13, and the air extraction pump 15 and pressure relief valve 16 are arranged on the sealing cover 14.

[0023] In use, all the defoaming tanks 13 are filled with paint through the liquid inlet assembly and the liquid inlet pipe 10, and the corresponding stirring assembly in each defoaming tank 13 is started to stir the paint to prevent the paint from solidifying, and the air pump 15 is started to pump air out of the interior, so that the tank body 12 and the defoaming tank 13 are in a negative pressure state and maintain a constant pressure. During this period, the stirring of the stirring assembly can accelerate the outgassing of the bubbles in the paint, so that the paint is bubble-free. The first electromagnetic valve on the liquid outlet pipe of one of the tank bodies 12 is opened, and the paint in which the bubbles are outgassed in the tank body 12 is supplied to the overall coating machine through the liquid supply assembly. The remaining single small treatment tanks continue the above defoaming action. When the paint in the defoaming tank is completely discharged, the first electromagnetic valve 17 corresponding to the liquid outlet pipe 11 is closed. Then, the first electromagnetic valve 17 on the liquid outlet pipe 11 of another defoaming tank is opened, and the above action is repeated. The closed single small treatment tank is first depressurized by the pressure relief valve 16 to balance the pressure difference between the inside and outside, and then the liquid inlet pipe 10 and the liquid inlet assembly are used to supplement the liquid and repeat the defoaming action. The large treatment tank is divided into multiple single small treatment tanks, and the supply of the paint is carried out in sequence. The stability of the paint supply is maintained, and each single small treatment tank can be individually defoamed in real time. Compared with the existing large single treatment tank, if physical defoaming is required during the supply, the machine needs to be stopped. The paint supply device of the present application improves the defoaming efficiency and ensures the stability of the paint supply.

[0024] In a preferred embodiment of the crop, the cross section of the defoaming tank 13 in the present application is a tapered shape that is wide at the top and narrow at the bottom.

The tank body 12 is outwardly provided with a sewage outlet, and the sewage outlet is provided with a valve body 22. The sewage outlet is arranged flush with the sealing plate 21. During the defoaming process of the paint by the stirring assembly, a large amount of outgassed bubbles may overflow, especially when the paint is at a high position. The sealing plate 21 can receive the overflowed bubbles, and the bubbles can be discharged through the sewage outlet during cleaning.

[0027] In a preferred embodiment of the crop, the outlet end of the liquid inlet pipe 10 is provided with an elbow 23, which is arranged towards the inner side wall of the defoaming tank 12. When the liquid is replenished, the elbow 23 can make the coating adhere to the tank wall of the defoaming tank, reduce the contact with air, and reduce the generation of bubbles.

[0028] In a preferred embodiment of the crop, the liquid inlet assembly includes a replenishment pump 24, which is connected with a liquid inlet joint 25, and each liquid inlet pipe 1 is connected with the liquid inlet joint 25. When the replenishment pump 24 sucks the coating, the first electromagnetic valve 17 on the corresponding liquid inlet pipe 10 is opened through the liquid inlet joint 25, so that the coating can be distributed directionally, thereby forming a circulating distribution process.

[0029] In a preferred embodiment of the crop, the liquid supply assembly includes a liquid supply joint 26, which is throughly arranged with each liquid outlet pipe 11, and the liquid supply joint 26 is also throughly arranged with a liquid supply pipe 27, and the liquid supply pipe 27 is also provided with a second electromagnetic valve 28. The coating with bubbles generated by the liquid supply assembly is stably supplied to the coating machine, and the stable supply is completed.

[0030] In a preferred embodiment of the crop, the liquid supply joint 26 is also externally connected with a liquid return pipe 29. The liquid return pipe 29 can recycle the coating remaining in the treatment tank after production is completed, thereby reducing waste.

[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
