Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of gluing, especially relates to a quantitative gluing mechanism. BACKGROUND

[0002] At present, in a branch of packaging boxes, the paper box is composed of the outer layer of the wrapping paper and the inner layer of the hard paperboard. The paper box with this structure needs to be filled with the inner space by the inner mold to facilitate the molding of the inner layer of the inner box, then the glue is applied on the inner surface of the outer layer of the wrapping paper and is attached to the outer surface of the inner box, and finally the paper box is compacted. The paper box needs to be glued during packaging. The traditional manual automatic gluing is point-shaped or linear, which is uneven and cannot meet the process requirements for the gluing area. The automatic glue spraying, such as the pneumatic type forming gluing device for paper box processing with the patent number CN213167112U, adopts the spraying mode, which has requirements for the viscosity and rising force of the glue. The high-viscosity and high-rising force glue is difficult to atomize, and the spraying effect is poor. During the spraying process, the atomization or sol is easily produced, which pollutes the product and the working environment and has the occupational health risk. SUMMARY

[0003] The utility model aims at the above-mentioned technical problems, and provides a quantitative gluing mechanism, which can guarantee the gluing efficiency and the air quality of the working environment.

[0004] Therefore, the utility model provides a quantitative gluing mechanism, which comprises:

[0005] A gluing table is used for containing the paper box to be glued.

[0006] A glue supply assembly is used for supplying the glue.

[0007] A gluing assembly comprises a gluing plate and a moving assembly. The gluing plate is connected with the glue supply assembly. The glue supply assembly makes the gluing plate have the glue. The moving assembly is used for driving the gluing plate to be close to and contact the paper box on the gluing table, and the glue is applied to the paper box.

[0008] In the technical scheme, the paper box is placed on the gluing table. The glue supply assembly supplies the glue to the gluing plate of the gluing assembly, so that the gluing plate is full of the glue. The moving assembly drives the gluing plate to be close to and contact the paper box on the gluing table, and the glue is transferred to the paper box to realize the gluing of the surface of the paper box. After the gluing is completed, the moving assembly drives the gluing plate to retreat and reset to be far away from the paper box, so that the paper box is conveniently fed and discharged, and the next gluing is prepared. The mechanism can guarantee the gluing efficiency and prevent the sol after the atomization of the spray from being scattered in the working environment, so that the air quality of the working environment is guaranteed.

[0009] Further, the glue coating plate comprises a porous plate and an elastic liquid suction member, the porous plate is attached to and connected with the elastic liquid suction member, the porous plate is connected with the glue supply assembly, the glue flow channel is arranged in the porous plate, and a plurality of communication holes are arranged on the side of the porous plate facing the elastic liquid suction member, and the communication holes are communicated with the glue flow channel.

[0010] In the technical solution, the glue enters the porous plate through the glue supply assembly, spreads in the glue flow channel of the porous plate, fills the entire glue flow channel, and spreads to the communication holes, and the elastic liquid suction member on the surface of the porous plate can uniformly suck the glue liquid by using the liquid capillary effect.

[0011] Further, the elastic liquid suction member is a sponge.

[0012] Further, the moving assembly comprises a moving air cylinder, the moving air cylinder is fixedly arranged on the placement plate, and the output end of the moving air cylinder is fixedly connected with the side of the porous plate away from the elastic liquid suction member.

[0013] Further, the placement plate is connected with a universal adjusting frame.

[0014] In the technical solution, the position and the inclination angle of the moving air cylinder can be adjusted through the universal adjusting frame, that is, the position and the inclination angle of the porous plate are adjusted, so that the requirements of different directions, different positions and different glue coating surface shapes can be met.

[0015] Further, a glue scraping frame is fixedly arranged on the placement plate, the glue scraping frame is annularly arranged on the outer periphery of the glue coating plate, the glue scraping frame is slidingly arranged with the glue coating plate, and a collecting structure is arranged on the glue scraping frame.

[0016] Further, the inner circle of the conical glue scraping frame is conical and comprises a large end and a small end, the collecting structure comprises a plurality of collecting holes which are arranged at intervals and are arranged on the inner circle of the glue scraping frame close to the small end and close to the large end, a communication groove is arranged between the collecting holes, a glue receiving box is arranged at the lower end of the glue scraping frame, and the glue receiving box is communicated with the collecting holes and is used for containing the collected glue.

[0017] In the technical solution, when the glue coating plate is moved outward to approach the paper box by the moving air cylinder, the sponge full of glue will swell, and the excess glue around the sponge will be scraped off in the process of the sponge moving outward to approach the paper box, so that the glue on the paper box is prevented from flowing too much, the scraped glue moves in the inner circle of the conical glue scraping frame and flows into the collecting holes and the communication groove, and finally flows into the glue receiving box from the collecting holes and is collected.

[0018] Further, an L-shaped positioning plate for positioning the paper box is arranged on the glue coating table.

[0019] Further, the glue supply assembly comprises a glue storage tank, a compressed air inlet pipe, a pressure regulating valve, a glue supply pipe and a solenoid valve.

[0020] In the technical solution, the compressed air inlet pressure is adjusted to an appropriate value by the pressure regulating valve, the solenoid valve is controlled by a square wave output by a PLC, and the glue is quantitatively supplied to the porous plate according to a certain frequency of on-off. The glue amount parameterization control can be realized by adjusting the on-off time ratio (duty ratio), the glue is quantitatively supplied to the glue coating plate by the solenoid valve, and then is uniformly adsorbed to the sponge and transferred to the paper box to be coated with glue, so that the quantitative and uniform glue coating is realized.

[0021] Further, the glue supply assembly comprises a glue storage tank, a compressed air inlet pipe, a pressure regulating valve, a glue supply pipe and a solenoid valve.

[0022] The glue coating device has the following beneficial effects:

[0023] 1. The glue coating device can ensure the glue coating efficiency and prevent the sol after the spray atomization from being scattered in the working environment, so that the air quality of the working environment is ensured.

[0024] 2. The universal adjusting frame can adjust the position and inclination angle of the moving cylinder, i.e. the position and inclination angle of the porous plate, so that the requirements of different directions, different positions and different glue coating surface shapes can be met.

[0025] 3. When the glue coating moving cylinder pushes the glue coating plate to move outward and approach the paper box, the sponge full of glue will expand, and the excess glue around the sponge will be scraped off in the process of the sponge moving outward and approaching the paper box, so that the glue coated on the paper box is prevented from flowing on the paper box, and the scraped glue will flow into the collecting hole and the communication groove in the process of moving in the conical glue scraping frame inner ring, and finally flows into the glue collecting box to be collected.
