Description

Technical Field

[0001] The invention relates to the field of base paper processing, in particular to a gluing and bonding device for base paper of paper cups. Background Art

[0002] Base paper is also called processing base paper. It is used for further processing into various processed papers, and the quality varies with the processing requirements. For example, the base paper for printing coated paper requires the paper to be tight, white and delicate, uniform in thickness, and have good coating strength. The base paper for steel paper requires soft texture and good absorption, and will not cause the finished product to bubble and delaminate. The base paper for copying wax paper requires the paper to be flexible and have slender fibers so that it is not easy to break when using an iron pen to write.

[0003] The processing of paper cup base paper requires processing of the base paper, usually by bonding two base papers with different properties together, and then cutting them into corresponding sizes for bending. However, the existing bonding is done manually by gluing, which is slow and inefficient.

[0004] Therefore, it is necessary to design an automatic gluing and gluing device for paper cup base paper. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the existing bonding is carried out by manual gluing, which is slow and inefficient.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a gluing and bonding device for paper cup base paper, the gluing and bonding device includes a bonding device frame, the bonding device frame is divided into a left frame and a right frame, the left frame is located on the left side of the right frame, a pair of raw material rollers with bonded materials are installed on the right frame, the left frame is installed with a gluing component, a bonding component and a winding roller, the gluing component is used to apply glue to the opposite sides of the bonded material, the bonding component is used to press the glued bonded material, the gluing component is located on the left side of the bonding component, and the winding roller is located on the left side of the bonding component.

[0007] The glue coating component comprises a glue coating tube with a hollow interior. The interior of the glue coating tube contains glue required for bonding, and a leakage groove is provided at the bottom of the glue coating tube.

[0008] The glue coating assembly also includes a hollow glue-spinning roller, which is rotatably connected to the inside of the glue coating tube. The glue required for bonding is stored inside the glue-spinning roller. A plurality of flow holes are opened on the surface of the glue-spinning roller, and plug balls are arranged on the outside of the plurality of flow holes. Elastic bands are fixedly connected to both sides of the plug balls, and the other end of the elastic bands is fixedly connected to the surface of the glue-spinning roller.

[0009] A motor is fixedly installed on the side wall of the left frame, two ends of the glue coating tube are fixedly connected in the left frame, and the output shaft of the motor is fixedly connected to one end of the glue throwing roller.

[0010] The bonding assembly includes a bonding roller, and slide grooves are provided on both sides of the inner wall of the left frame. A slider is slidably connected inside the slide groove. The bonding roller is rotatably connected to the slider. Telescopic rods are installed at both ends of the slide groove, and the other end of the telescopic rod is fixedly connected to the slider.

[0011] The left frame is rotatably connected with a pair of transition rollers, and the pair of transition rollers is located on the right side of the glue coating assembly.

[0012] A scraper is provided at the bottom of the glue coating tube, and the scraper is located on the left side of the drain groove.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. By setting up a glue coating tube, when the two materials to be bonded pass through the glue coating tube, the glue inside the glue coating tube will flow from the leakage groove onto the materials at the bottom of the glue coating tube, and the effect of automatic gluing can be achieved at this time;

[0015] 2. By setting a plug ball, the elastic belt always pulls the plug ball down. When the glue roller rotates, the plug ball will be thrown away due to the centrifugal force, and the glue inside the glue roller will be thrown into the glue coating tube (automatically adding glue to the glue coating tube), and then flow out from the leakage groove for gluing. When the glue roller does not rotate, due to the force of the elastic belt, the plug ball will be pulled down to block the flow hole, preventing the glue from flowing out and wasting when gluing is not needed;

[0016] 3. A telescopic rod is provided, and the extension and retraction of the telescopic rod are uniformly controlled by the controller. When the telescopic rod is extended, it will push the slider to slide relative to each other, thereby reducing the distance between the bonding rollers. When the telescopic rod is retracted, it will pull the slider to slide relative to each other, thereby increasing the distance between the bonding rollers, thereby automatically adjusting the distance between the bonding rollers.

DETAILED DESCRIPTION

[0025] See also Figure 1-6 The gluing and bonding device comprises a bonding device frame 1, which is divided into a left frame and a right frame. The left frame is located on the left side of the right frame. A pair of raw material rollers 2 with bonded materials are installed on the right frame. The left frame is installed with a gluing component, a bonding component and a winding roller 3. The gluing component is used to apply glue to the opposite sides of the bonded materials, and the bonding component is used to press the glued bonded materials. The gluing component is located on the left side of the bonding component, and the winding roller 3 is located on the left side of the bonding component; the two raw materials to be bonded on the raw material roller 2 first pass through the transition roller 15, and then pass through the upper and lower surfaces of the gluing tube 4, and then pass through the bonding pressing roller 11 to press them together and then be collected by the winding roller 3.

[0026] The glue coating component includes a glue coating tube 4 with a hollow interior. The interior of the glue coating tube 4 contains glue required for bonding, and a leakage groove 5 is opened at the bottom of the glue coating tube 4; when the two raw materials to be bonded pass through the glue coating tube 4, the glue inside the glue coating tube 4 will flow from the leakage groove 5 onto the raw materials at the bottom of the glue coating tube 4, and the effect of automatic gluing can be achieved at this time.

[0027] The glue coating assembly also includes a hollow glue-spinning roller 6, which is rotatably connected to the inside of the glue coating tube 4. The glue required for bonding is stored in the glue-spinning roller 6. A plurality of flow holes 7 are opened on the surface of the glue-spinning roller 6, and plug balls 8 are arranged on the outside of the plurality of flow holes 7. Elastic bands 9 are fixedly connected to both sides of the plug balls 8, and the other end of the elastic band 9 is fixedly connected to the surface of the glue-spinning roller 6; the elastic band 9 always pulls the plug balls 8 down, and when the glue-spinning roller 6 rotates, the plug balls 8 will be thrown away due to the action of centrifugal force, and the glue inside the glue-spinning roller 6 will be thrown into the glue coating tube 4 (automatically adding glue to the glue coating tube 4), and then flow out from the leakage groove 5 for gluing operation. When the glue-spinning roller 6 does not rotate, due to the action of the elastic band 9, the plug balls 8 will be pulled down to block the flow holes 7, so as to prevent the glue from flowing out and causing waste when gluing is not needed.

[0028] A motor 10 is fixedly installed on the side wall of the left frame, and both ends of the glue coating tube 4 are fixedly connected to the left frame. The output shaft of the motor 10 is fixedly connected to one end of the glue throwing roller 6; the motor 10 gives power to the glue throwing roller 6 to rotate, so that the glue throwing roller 6 can rotate automatically to replenish glue for the glue coating tube 4.
