Description

Technical Field

[0001] This utility model relates to the field of coating equipment application technology, and in particular to a coating liquid circulation conveying mechanism for an adhesive applicator. Background Technology

[0002] Packaging paper consists of an outermost face paper and an inner release paper. The face paper serves an aesthetic purpose, while the release paper is used to shape the face paper. The face paper and release paper are made of different materials and need to be bonded together with glue and backing liquid.

[0003] When the coating machine coats the paper, it moves the paper and then the rotating rollers on it rotate in a square dish containing coating liquid, so that the coating liquid adheres to the rollers. The rotating rollers then apply the coating liquid to different parts of the paper. When the coating liquid in the square dish is low or used up, the coating liquid in the material tank is poured directly into the square dish. When there is enough coating liquid in the square dish, the addition is stopped.

[0004] During prolonged operation, the coating solution may solidify, affecting its application to the paper. Utility Model Content

[0005] The purpose of this invention is to provide a coating liquid circulation conveying mechanism for a glue applicator, which has the advantage of preventing the coating liquid in the glue applicator from solidifying during long-term operation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A coating liquid circulation conveying mechanism for a glue coating machine includes a frame with a square dish containing coating liquid fixedly connected to the frame. The square dish has an opening at its bottom, and a drain pipe is fixedly connected to the opening. A material bucket containing coating liquid is placed below the drain pipe. A mounting frame is located next to the frame, and a booster pump is fixedly connected to the mounting frame. The booster pump has a first conveying pipe connected to its inlet and a second conveying pipe connected to its outlet. The opening of the first conveying pipe is located in the material bucket, and the opening of the second conveying pipe is located in the square dish.

[0008] Using the above technical solution, the coating liquid in the square dish flows into the material tank. The booster pump draws the coating liquid from the material tank into the first conveying pipe. The coating liquid then flows from the first conveying pipe into the second conveying pipe and finally returns to the square dish, thus circulating the coating liquid. This ensures that there is enough coating liquid in the square dish while increasing the fluidity of the coating liquid and preventing it from solidifying and affecting the coating of the paper.

[0009] Preferably, a valve is installed on the drain pipe.

[0010] By adopting the above technical solution, the flow rate of the coating liquid into the material tank is adjusted to prevent the booster pump from emptying the material tank when the flow rate is less than the suction rate of the booster pump, which would cause the booster pump to run dry and damage the booster pump. When the flow rate of the coating liquid into the material tank is greater than the suction rate of the booster pump, the amount of coating liquid in the square dish will be greatly reduced, thus affecting the coating of the paper.

[0011] Preferably, the conveying pipe is a rubber hose.

[0012] The above technical solution facilitates the movement of the delivery pipe and the booster pump.

[0013] Preferably, the booster pump is a diaphragm booster pump.

[0014] The above technical solution improves the transport efficiency of viscous fluids.

[0015] Preferably, a baffle is fixedly connected to the side of the square dish near the material bucket, and the upper part of the baffle is inclined towards the inside of the square dish.

[0016] The above technical solution prevents the coating liquid in the square dish from splashing out and affecting the environment.

[0017] Preferably, a connecting plate is fixedly connected between the baffle and the frame.

[0018] The above technical solution improves the fixing effect of the baffle. Attached Figure Description

[0025] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0026] See Figures 1 to 5 A coating liquid circulation conveying mechanism for a glue applicator includes a frame 1, to which a square dish 2 containing coating liquid is fixedly connected. A baffle 10 is fixedly connected to the side of the square dish 2, with its upper part inclined inward towards the inside of the dish 2 to prevent the glue applicator roller from carrying coating liquid out of the dish 2 when it rotates within the dish 2, thus avoiding environmental impact. A connecting plate 11 is fixedly connected between the baffle 10 and the frame 1 to improve the fixing effect of the baffle 10. An opening is provided at the bottom of the square dish 2, and a drain pipe is fixedly connected to the opening. 3. A valve 9 is installed on the drain pipe 3. A material bucket 4 is placed below the drain pipe 3. The material bucket 4 is fixedly connected to the side of the square dish 2 with a baffle 10. The material bucket 4 contains coating liquid. A mounting frame 5 is set next to the frame 1. A diaphragm booster pump 6 is fixedly connected to the mounting frame 5. The diaphragm booster pump 6 is suitable for conveying viscous fluids. The inlet of the booster pump 6 is connected to a first conveying pipe 7. The outlet of the booster pump 6 is connected to a second conveying pipe 8. The opening of the first conveying pipe 7 is located in the material bucket 4. The opening of the second conveying pipe is located in the square dish 2. The conveying pipe is a rubber hose, which facilitates the movement of the booster pump 6 and the conveying pipe.

[0027] Working principle: The coating liquid in square dish 2 flows into container 4. Booster pump 6 draws the coating liquid from container 4 into delivery pipe 7. The coating liquid then flows from delivery pipe 7 into delivery pipe 2, finally returning to square dish 2. This circulating delivery system ensures sufficient coating liquid in square dish 2 while increasing its fluidity and preventing solidification. The flow rate of the coating liquid into container 4 can be adjusted by valve 9 on drain pipe 3 to match the delivery speed of booster pump 6, preventing a situation where the flow rate of the coating liquid into container 4 is less than the suction speed of booster pump 6. The booster pump 6 will draw a large amount of coating liquid into the square dish 2, exceeding the capacity of the square dish 2, thus overflowing the square dish 2. It will also cause the booster pump 6 to draw out the coating liquid in the material tank 4, causing the booster pump 6 to run dry, which will damage the booster pump 6. When the rate at which the coating liquid flows into the material tank 4 is greater than the rate at which the booster pump 6 draws it in, the amount of coating liquid in the square dish 2 will decrease significantly, thus affecting the coating of the paper. When the coating liquid in the square dish 2 is almost used up, the valve 9 can be closed to draw the coating liquid in the material tank into the square dish 2. When there is enough coating liquid, the valve 9 can be opened again.
