[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Description of the drawings:

[0015] Figure 1 It is a top cross-sectional view of the utility model;

[0016] Figure 2 yes Figure 1 KK cross-section diagram. Specific implementation method:

[0018] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0019] The conveying and circulating device of the packaging film coating of the packaging bag of the present invention comprises a coating containing tray 1 and coating 2 contained in the coating containing tray. The coating is a coating for printing, which is a prior art and will not be described in detail here. The coating containing tray 1 is a rectangular stainless steel trough-shaped thin shell.

[0020] A rotating roller 3 for rolling the paint is arranged above the paint containing tray, and the rotating roller 3 is driven to rotate by a pulley or a gear transmission mechanism extending out of the paint containing tray.

[0021] A partition 4 is vertically provided in the paint receiving tray 1 near the outer wall plate 101, and the partition 4 is spaced from the outer wall plate 101 to form a paint channel 6 therebetween; the partition 4 may also be made of stainless steel, and the lower portion of the partition 4 is fixedly connected to the bottom surface of the paint receiving tray and is not permeable to paint, a first notch 5 is provided on the partition 4 near the first side portion of the paint receiving tray, and a second notch 7 is provided on the outer wall plate of the paint receiving tray near the second side portion of the paint receiving tray, and the first notch 5 and the second notch 7 do not penetrate to the bottom surface of the paint receiving tray.

[0022] The second notch 7 is connected with an inclined material guide trough 8, which is made of stainless steel and has a U-shaped cross-section after being stamped. A material holding barrel 9 for receiving the paint output by the material guide trough is provided on the ground below the material outlet of the material guide trough. The material holding barrel 9 can be a plastic barrel, which is connected to a delivery pump 11 through a delivery pipeline 10 (plastic hose). The output end of the delivery pipeline 10 is arranged on the second side of the paint receiving tray and is located on the side of the partition close to the rotating roller. The paint enters from the second side of the paint receiving tray and enters the material holding barrel after passing through the first notch, the paint channel, the second notch and the material guide trough in sequence, so that the paint forms a circuitous flow channel in the paint receiving tray, which increases the flow distance and improves the fluidity of the paint.

[0023] In order to prevent the paint from agglomerating after being output, or to make the output material more delicate, a cloth bag 12 is provided on the output end of the above-mentioned material delivery pipeline. The cloth bag 12 has fine pores. When the paint is input, under a certain pressure (the delivery pressure of the delivery pump), the paint seeps out from the fine pores of the cloth bag and then flows into the paint holding tray. The cloth bag 12 not only plays a filtering role, but also plays a role in buffering the output material, thereby avoiding splashing of the material liquid directly discharged from the output end of the material delivery pipeline.

[0024] In order to facilitate the discharge and guiding of materials, a funnel 13 is provided on the feed inlet of the above-mentioned material storage barrel, and the large end of the funnel faces upward and is located directly below the discharge port of the material guide trough. The tube body connected to the small end of the funnel 13 passes through the hole on the sealing cover on the upper part of the material storage barrel. Since a sealing cover is provided on the upper part of the material storage barrel, the contact between the paint and the air can be reduced. The interior of the material storage barrel can only be connected to the outside through the tube body connected to the small end of the funnel and the material delivery pipeline.

[0025] The working method of the conveying and circulating device of the packaging film coating of the packaging bag of the utility model is as follows: the coating is loaded in a material holding barrel, one end of a material conveying pipeline connected in series with a conveying pump is put into the material holding barrel, the other end of the material conveying pipeline is put into the second side portion of the coating holding tray and is located on the side of the partition close to the rotating roller, the conveying pump is started, and under the action of the conveying pump, the coating is input from the material holding barrel to the second side portion of the coating holding tray, passes through the first notch, the coating channel, the second notch and the material guide groove in sequence, and then returns to the material holding barrel. Since the coating is in continuous circulation, it is helpful to avoid agglomeration caused by long-term stagnation of the coating, which affects the subsequent printing quality.

[0026] By setting the partition, the paint forms a circuitous flow channel in the paint holding tray, which increases the flow distance and improves the fluidity of the paint.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
