[0002] At present, packaging cartons or paper boxes are everywhere in daily life. Packaging cartons or paper boxes play a crucial role in product transportation. Nowadays, for the convenience of transporting cartons or paper boxes, the cartons or paper boxes are designed to be directly formed by pasting two corrugated paperboards. During the forming process of the cartons or paper boxes, only the two sides of the corrugated paperboard need to be coated with glue and bonded. When transported to the place where cartons or paper boxes are needed, the sheet-shaped cartons or paper boxes are then opened into the shape of a box body. The traditional coating of cartons or paper boxes is usually carried out by manual coating, which has low efficiency. The staff performs the coating operation for a long time, increasing the labor intensity of the staff and not meeting the requirements of mass production. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a packaging paper glue coating device, which can improve the glue coating efficiency of packaging paper, reduce the labor intensity of staff, and avoid the phenomena of glue leakage and adhesion on the surface of packaging paper.

[0007] The glue coating mechanism includes a glue leakage roller and a first glue coating roller arranged side by side. A glue leakage device is arranged above the glue leakage roller so that the glue leakage roller is evenly distributed with glue. Along the conveying direction, the first glue coating roller is located behind the glue leakage roller to evenly coat the surface of the packaging paper.

[0008] A positioning component is arranged above the first glue coating roller, and the positioning component can abut and position the packaging paper output from the bottom of the glue coating roller.

[0009] Further, the glue leakage device includes a glue filling tank arranged above the glue coating roller. A glue leakage port is opened on the glue filling tank, and the glue leakage port leads to the surface of the glue coating roller. The glue filling tank is connected to a glue tank through a connecting pipe.

[0010] Further, the glue - applying mechanism further includes a second glue - applying roller. Along the conveying direction, the second glue - applying roller is located in front of the glue - leaking roller, that is, the first glue - applying roller and the second glue - applying roller are respectively located on both sides of the glue - leaking roller.

[0011] Further, the driving device includes a driving motor, a driving gear, and a pair of driven gears meshing with the driving gear; the glue - leaking roller is connected to the output end of the driving motor, the driving gear is arranged at the end of the glue - leaking roller, and the pair of driven gears are respectively connected to the first glue - applying roller and the second glue - applying roller.

[0016] When the present utility model is in use, the wrapping paper is conveyed by the first conveying device. When it is conveyed below the glue - applying mechanism, the glue - leaking roller rotates to coat the surface of the wrapping paper with glue. Then, the first glue - applying roller further levels the glue on the surface of the wrapping paper, making the glue more uniform and thinner on the surface of the wrapping paper. In order to maintain the stability of the conveying of the glue - applied wrapping paper, the present utility model uses the lower end of the positioning assembly to abut against the surface of the wrapping paper to position the wrapping paper, so that the wrapping paper is conveyed to the surface of the second conveying device along the conveying path and is conveyed more stably, and the adhesion phenomenon is also avoided, improving the glue - applying efficiency of the wrapping paper and reducing the labor intensity of the staff.

Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0022] Embodiment 1

[0023] A packaging paper gluing device includes a first conveying device 1 for conveying the packaging paper 2 and a second conveying device 7 located at the conveying end of the first conveying device 1; it should be noted that the first conveying device 1 and the second conveying device 7 can be conveying devices such as conveyor belts or conveying plates;

[0024] A gluing mechanism is horizontally arranged between the first conveying device 1 and the second conveying device 7, and an end of the gluing mechanism is connected with a driving device for driving the gluing mechanism to rotate;

[0025] The gluing mechanism includes a glue leakage roller and a first gluing roller 6 arranged side by side. A glue leakage device is arranged above the glue leakage roller so that the glue leakage roller is evenly distributed with glue. Along the conveying direction, the first gluing roller 6 is located behind the glue leakage roller to make the coating on the surface of the packaging paper 2 uniform;

[0026] A positioning assembly is arranged above the first gluing roller 6, and the positioning assembly can abut and position the packaging paper 2 output from the bottom of the gluing roller.

[0027] Working principle: When the utility model is in use, the wrapping paper 2 is conveyed by the first conveying device 1. When it is conveyed below the gluing mechanism, the surface of the wrapping paper 2 can be coated with glue under the rotation of the glue leakage roller, and then the first glue coating roller 6 further levels the glue on the surface of the wrapping paper 2, making the glue more uniform and thinner on the surface of the wrapping paper 2. In order to maintain the stability of the conveyed wrapping paper 2 after gluing, the utility model uses the lower end of the positioning component to abut against the surface of the wrapping paper 2 to position the wrapping paper 2, so that the wrapping paper 2 is conveyed to the surface of the second conveying device 7 along the conveying path and is conveyed more stably, and the adhesion phenomenon is also avoided, improving the gluing efficiency of the wrapping paper 2 and reducing the labor intensity of the staff.

[0028] More specifically, the positioning component includes a positioning rod 10 arranged above the first glue coating roller 6 and a plurality of positioning arms 9 arranged on the positioning rod 10. The positioning arms 9 extend towards the second conveying device 7 and the lower ends of the positioning arms 9 can abut against the surface of the wrapping paper 2. When the wrapping paper 2 is conveyed forward by the second conveying device 7, it can be abutted by the lower ends of the positioning arms 9, thereby positioning the wrapping paper 2 to a certain extent, avoiding the offset of the wrapping paper 2, and at the same time, the wrapping paper 2 can be separated to a certain extent in advance to avoid the adhesion phenomenon between the wrapping paper 2 and the first glue coating roller 6.

[0029] In this embodiment, the glue leakage device includes a glue filling tank 8 arranged above the glue coating roller. The glue filling tank 8 is provided with a glue leakage port, and the glue flowing out of the glue leakage port leads to the surface of the glue coating roller. The glue filling tank 8 is connected to a glue tank 5 through a connecting pipe 4. During use, the glue is sent from the glue tank 5 to the connecting pipe 4 and the glue filling tank 8, and then discharged from the glue leakage port and flows to the surface of the glue coating roller. Due to the rotation of the glue coating roller, the whole glue coating roller can be evenly distributed with glue, so that the surface of the wrapping paper 2 can be coated with glue more smoothly and evenly.

[0030] In this embodiment, the gluing mechanism further includes a second glue coating roller 3. Along the conveying direction, the second glue coating roller 3 is located in front of the glue leakage roller, that is, the first glue coating roller 6 and the second glue coating roller 3 are respectively located on both sides of the glue leakage roller. In this way, when the wrapping paper 2 is conveyed, the second glue coating roller 3 can pre-push and position the wrapping paper 2 to make it more smoothly advanced below the glue leakage roller.

[0031] In this embodiment, the driving device includes a driving motor 13, a driving gear 12, and a pair of driven gears 11 meshing with the driving gear 12; the glue leakage roller is connected to the output end of the driving motor 13, the driving gear 12 is arranged at the end of the glue leakage roller, and a pair of the driven gears 11 are respectively connected to the first glue coating roller 6 and the second glue coating roller 3; in this way, the glue leakage roller and the driving gear 12 can be driven to rotate under the action of the driving motor 13, and at the same time, the driving gear 12 drives the driven gears 11 to rotate synchronously, and then the first glue coating roller 6 and the second glue coating roller 3 rotate synchronously, so that the glue leakage roller, the first glue coating roller 6 and the second glue coating roller 3 can rotate synchronously to realize the conveying, glue coating and flattening of the wrapping paper 2, and the working process is smoother and more stable, ensuring the stability and quality of the glue coating of the wrapping paper 2.

[0032] In order to avoid the phenomenon that after the wrapping paper 2 is coated with glue, there is excess glue overflowing and remaining on the surface of the second conveying device 7; in this embodiment, the first glue coating roller 6 is a special-shaped roller, and from the middle to both sides, the outer diameter of the special-shaped roller gradually decreases. At the same time, a conveying roller 14 is also arranged horizontally between the conveying end of the first conveying device 1 and the conveying front end of the second conveying device 7. One side of the conveying roller 14 is connected with a motor to drive its rotation, and the top end of the conveying roller 14 is flush with the conveying end faces of the first conveying device 1 and the second conveying device 7; in the prior art, the reason for the glue leakage phenomenon is mainly that the first glue coating roller 6 is a regular cylindrical roller, and when the surface of the wrapping paper 2 is integrally squeezed and flattened, if there is excess glue at the edge of the wrapping paper 2, glue leakage will occur on the surface of the second conveying device 7; while in the present invention, the first glue coating roller 6 is designed as a special-shaped roller, and from the middle to both sides, the outer diameter of the special-shaped roller gradually decreases. In this way, when the wrapping paper 2 is conveyed to the lower part of the first glue coating roller 6, the surface of the wrapping paper 2 contacts the convex part in the middle of the special-shaped roller, and the glue on the surface of the wrapping paper 2 is squeezed and coated. The side edges of the wrapping paper 2 cannot contact the two sides of the first glue coating roller 6. At the same time, under the rotation action of the bottom conveying roller 14, the wrapping paper 2 is driven to transport forward. Under the dual action of the conveying roller 14 and the first glue coating roller 6, the wrapping paper 2 is stably conveyed towards the second conveying device 7, and at the same time, the extrusion of the side edges of the wrapping paper 2 is avoided, so that the glue will not overflow to the surface of the second conveying device 7, protecting the integrity of the surface of the second conveying device 7 and the stability of the conveying of the wrapping paper 2, and avoiding glue leakage and adhesion phenomena.

[0033] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
