Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag printing production devices, and particularly relates to a packaging bag printing production device. Background Technique

[0002] A packaging bag refers to a bag used for packaging various items, making it convenient to transport goods during the production and circulation process and easy to store. It is widely used in daily life and industrial production. Actual figures show that 80% of plastic bags after use are ultimately transported to landfills for disposal like general garbage, and only 7% of plastics are recycled. During the production process of packaging bags, a printing device is used to improve the aesthetics of the appearance of the packaging bags;

[0003] However, during the use of existing packaging bag printing devices, during the transportation of packaging bags through a conveyor belt, the packaging bags are exposed to the outside, resulting in dust and impurities easily falling on the upper surface of the packaging bags, leading to a decline in the quality of the printed patterns on the packaging bags. Moreover, if the printed patterns are not dried in a timely manner after printing, they are easily worn. Most drying is done by heat sealing for the packaging bags after printing, and the air outlet is fixed, resulting in a fixed blowing and drying area, which easily leads to uneven drying;

[0004] Therefore, this application provides a packaging bag printing production device to meet the requirements. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the above background technique, and to propose a packaging bag printing production device.

[0006] The technical problem to be solved by the utility model is to provide a packaging bag printing production device to solve the problems that impurities and dust above the packaging bags in the existing packaging bag printing production device are not easy to clean and the drying after printing is uneven.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A packaging bag printing production device includes: a printing device main body, a conveyor belt is fixedly arranged in the middle of the front surface of the printing device main body, a dust collector is fixedly connected to the top end of the printing device main body through a nut, a printing machine is fixedly connected to the middle of the front surface of the printing device main body, a support rod is fixedly connected to the middle of the left side of the printing device main body, a support frame is arranged on the left side of the front surface of the printing device main body, and a heating blower is fixedly connected to the right side of the front surface of the printing device main body.

[0009] Preferably, a support plate is fixedly connected to the right side of the support rod, a brush strip is embedded at the bottom end of the support plate, a first spring is fixedly connected between the brush strip and the support plate, and the bottom end of the brush strip is closely attached to the upper surface of the conveyor belt.

[0010] Preferably, the cross-section of the brush strip is in a "V" shape that tilts to the right when viewed from above.

[0011] Preferably, an adsorption hood is fixedly connected to the lower part of the left side surface of the support plate, and the adsorption hood is communicated with a vacuum cleaner through a conduit.

[0012] Preferably, sliding grooves are formed in the front and rear sides of the inner wall of the support frame, sliders are slidably connected to the inside of the sliding grooves, a roller is fixedly connected between the two sliders, the roller is a convex hyperboloid, and a second spring is fixedly connected between the slider and the sliding groove.

[0013] Preferably, a rotary nozzle base is nested at the output end of the heating fan, and nozzles arranged at equal intervals in a ring shape are embedded at the bottom end of the rotary nozzle base.

[0014] Preferably, the nozzle is embedded at an inclined angle at the bottom of the rotary nozzle base.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, by setting the brush strip, when the packaging bag is transported for printing through the conveyor belt, the upper surface of the packaging bag will first be scraped and cleaned by the brush strip, so that impurities are not easily attached to the upper surface of the packaging bag, which affects the printing quality. After the cleaning is completed, the roller will squeeze the slider to move downward along the sliding groove through the second spring to squeeze the packaging bag, and the roller with a convex arc surface can squeeze the middle of the conveyor belt packaging bag to both sides, so that the packaging bag is not easily wrinkled during transportation, and the printing quality is improved.

[0017] In the above solution, by setting the heating fan, when the printed packaging bag is transported to the lower part of the heating fan through the conveyor belt, the heating fan will transport hot air into the rotary nozzle base and spray it out through the nozzles. When the nozzles spray hot air, a thrust will be generated to drive the rotary nozzle base to rotate, so that the rotary nozzle base rotates 360 degrees, so that the nozzles spray hot air downward 360 degrees to dry the printed packaging bag, effectively improving the drying uniformity.
