Description

Technical Field

[0001] This utility model relates to a box gluing machine, specifically a double-piece box gluing machine. Background Technology

[0002] In the packaging industry, cardboard box gluing is an indispensable part of the production process. Traditional cardboard box gluing methods mostly rely on manual operation, which not only requires a large investment of manpower but is also inefficient and difficult to guarantee in terms of gluing quality. With the rapid development of automation technology, some highly automated gluing machines have gradually appeared on the market, but most gluing machines still have some problems, such as large footprint and difficult maintenance.

[0003] Traditional carton gluing machines typically employ a single-piece conveyor line design, where the upper and lower carton pieces are conveyed and glued on separate lines. This method not only occupies a large area but also presents challenges due to the complex equipment structure, making installation, maintenance, and replacement of individual components relatively difficult, thus increasing production and time costs. Furthermore, while some existing carton gluing machines utilize automated conveying technology, manual alignment and gluing of the upper and lower carton pieces are still required, resulting in insufficient automation and persistent issues of cumbersome operation and low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a double-piece gluing machine to solve the problems of large footprint and low automation of traditional gluing machines.

[0005] This utility model is implemented as follows: A double-piece gluing machine, the structure of which includes a frame and a carton lower sheet conveying line and a carton upper sheet conveying line arranged on the frame; the carton lower sheet conveying line includes a lower paper feeding device, a lower paper feeding device, a lower paper pushing device, and a lower gluing device arranged sequentially and horizontally; the carton upper sheet conveying line includes an upper paper feeding device, a glue applicator, an upper paper feeding device, an upper paper pushing device, and an upper gluing device arranged sequentially and inclined downwards; the carton upper sheet conveying line is located above the carton lower sheet conveying line.

[0008] Furthermore, the upper paper feeding device includes an upper paper feeding frame, an upper paper feeding roller and an upper paper feeding baffle disposed on the upper paper feeding frame.

[0009] Furthermore, the upper end of the upper paper feed rack is a platform for stacking the upper sheets of the cardboard box, the upper end of the upper paper feed roller protrudes from the platform surface of the upper paper feed rack, and a suction hole is provided on the upper paper feed roller.

[0010] Furthermore, the upper paper feed baffle is perpendicular to the platform surface of the upper paper feed frame, and the vertical distance between the upper paper feed baffle and the upper paper feed roller allows only one carton sheet to pass through at a time.

[0011] Furthermore, the glue application device includes a drive roller, a pressure roller, a glue application roller, a glue tank, and a glue supply roller.

Detailed Implementation

[0021] like Figure 1 , Figure 2 As shown, this utility model includes a frame 1 and a carton lower sheet conveyor line and a carton upper sheet conveyor line mounted on the frame 1. The carton lower sheet conveyor line includes a lower paper feeding device 2, a lower paper feeding device 3, a lower paper pushing device 4, and a lower gluing device 5 mounted on the frame 1. These devices are adjacent to each other and arranged sequentially on a horizontal line. The carton upper sheet conveyor line includes an upper paper feeding device 6, a glue applicator 10, an upper paper feeding device 7, an upper paper pushing device 8, and an upper gluing device 9 mounted on the frame 1. These devices are arranged sequentially at a downward inclination. Among them, the upper paper feeding device 6 is located at the upper end, and the upper gluing device 9 is located at the lower end. The upper gluing device 9 and the lower gluing device 5 are arranged adjacent to each other, and the paper exit point of the lower gluing device 5 overlaps with the paper exit point of the upper gluing device 9. The upper and lower carton sheets are glued together in this overlapping section. All the devices of the carton upper sheet conveyor line are located above the carton lower sheet conveyor line, forming a layered layout structure to ensure precise alignment of the upper and lower carton sheets during the gluing process.

[0022] The upper paper feeding device 6 includes an upper paper feeding frame 6-1, upper paper feeding rollers 6-2 mounted on the upper paper feeding frame 6-1, and an upper paper feeding baffle 6-3. The upper paper feeding frame 6-1 serves as the basic support structure of the entire device, with a flat platform at its upper end for stacking carton top sheets. The upper end of the upper paper feeding rollers 6-2 protrudes from the platform surface of the upper paper feeding frame 6-1 to ensure contact with the bottommost carton top sheet. Several suction holes are provided on the upper paper feeding rollers 6-2, which are connected to a negative pressure device through pipelines to generate a strong suction force, thereby firmly adhering to the lower side of the bottommost carton top sheet. As the upper paper feeding rollers 6-2 rotate, the carton top sheets are fed to the paper coating and gluing device 10. The main function of the upper paper feeding baffle 6-3 is to ensure that the stacked carton top sheets are stably and sequentially conveyed during the conveying process without shifting or scattering. The upper paper feed baffle 6-3 is perpendicular to the platform surface of the upper paper feed frame 6-1. The vertical distance between the upper paper feed baffle 6-3 and the upper paper feed roller 6-2 ensures that only one carton sheet is allowed to pass through at a time.

[0023] The glue application device 10 includes drive rollers 10-1, pressure rollers 10-2, glue application rollers 10-3, glue tanks 10-4, and glue supply rollers 10-5. There are two sets of drive rollers 10-1, with two rollers in each set. One set of drive rollers 10-1 is located before and after the pressure rollers 10-2 and the glue application rollers 10-3, for a total of four drive rollers 10-1. This layout helps stabilize the movement direction of the carton and ensures accurate glue application. The two front drive rollers 10-1 receive the carton sheet from the upper paper feed device 6, while the two rear drive rollers 10-1 deliver the glued carton sheet to the upper paper feeding device 7.

[0024] The pressure roller 10-2 is located above the glue-coating roller 10-3. The pressure roller 10-2 works closely with the glue-coating roller 10-3 to clamp the upper sheet of the carton, ensuring that the glue can be evenly applied to the lower surface of the upper sheet of the carton. The distance between the pressure roller 10-2 and the glue-coating roller 10-3 is adjustable to accommodate cartons of different materials and thicknesses.

[0025] The glue-applying roller 10-3 is located below the pressure roller 10-2 and above the glue tank 10-4. The outer surface of the glue-applying roller 10-3 has a textured surface to precisely control the amount of glue applied, improving coating accuracy. The glue-applying roller 10-3 receives glue from the glue supply roller 10-5 and evenly coats it onto the lower surface of the carton upper sheet. The rotation of the glue-applying roller 10-3 and its contact with the carton ensure uniform glue application.

[0026] The glue tank 10-4 is located below the glue application roller 10-3, and the glue supply roller 10-5 is located inside the glue tank 10-4. The glue supply roller 10-5 cooperates with the glue application roller 10-3. The glue supply roller 10-5 is used to pick up the glue in the glue tank 10-4 and apply the picked-up glue onto the glue application roller 10-3. The rotation of the glue supply roller 10-5 and its contact with the glue application roller 10-3 ensures a continuous supply and uniform application of glue.

[0027] The gluing device can be used to apply glue to the upper or lower surfaces of the cardboard box, either partially or entirely.

[0028] The paper feeding device 7 is a suction conveyor belt that uses negative pressure to firmly attach the top sheet of the carton to the lower side of the conveyor belt, and smoothly transports the top sheet of the carton to the paper pushing device 8 as the conveyor belt rotates.

[0029] The paper-pushing device 8 receives the carton sheet from the paper-feeding device 7 and drives it downwards to the gluing device 9. The paper-pushing device 8 includes a paper-feeding roller 8-3, a paper-feeding flexible component 8-1, and a paper-feeding board 8-2 attached to the paper-feeding flexible component 8-1. The paper-feeding flexible component 8-1 drives the paper-feeding board 8-2, which pushes the carton sheet during movement, ensuring accurate positioning and entry into the subsequent gluing process. The paper-feeding flexible component 8-1 can be a chain, timing belt, etc. The paper-feeding roller 8-3 is located near the paper-feeding device 7 and primarily guides and assists the carton sheet into the path of the paper-feeding chain 8-1. By precisely controlling the speed and position of the feeding roller, it can be ensured that the carton sheet enters the paper-pushing device 8 with the correct posture and speed.

[0030] The lower paper feeding device 2 includes a lower paper feed frame 2-1, a lower paper feed conveyor belt 2-2 mounted on the lower paper feed frame 2-1, and a lower paper feed baffle 2-3. The lower paper feed conveyor belt 2-2 is a suction conveyor belt. The structure and function of the lower paper feed frame 2-1 and the lower paper feed baffle 2-3 are the same as those of the upper paper feed frame 6-1 and the upper paper feed baffle 6-3. The lower paper feed conveyor belt 2-2 generates negative pressure through a built-in suction system, which can firmly adhere the bottom sheet of the carton to the surface of the conveyor belt. As the conveyor belt rotates, the bottom sheet of the carton is smoothly transported to the lower paper feeding device 3. The design of the suction conveyor belt can not only effectively prevent the carton from shifting during transportation, but also avoid paper jams caused by static electricity or friction between the papers, ensuring the stable transmission of the bottom sheet of the carton.

[0031] The paper feeding device 3 is a conveyor belt used to transport the bottom sheet of the carton from the paper feeding device 2 to the paper pushing device 4.

[0032] The structure and function of the lower paper pusher 4 are the same as those of the upper paper pusher 8.

[0033] The paper-pushing device 4 receives the upper piece of the carton from the lower paper feeding device 3 and drives it to move to the lower gluing device 5. The paper-pushing device 4 includes a paper-pushing feed roller 4-3, a paper-pushing flexible component 4-1, and a paper-pushing board 4-2 attached to the paper-pushing flexible component 4-1. The paper-pushing flexible component 4-1 drives the paper-pushing board 4-2, which pushes the upper piece of the carton during movement, ensuring accurate positioning and entry into the subsequent gluing process. The paper-pushing flexible component 4-1 can be a chain, timing belt, etc. The paper-pushing feed roller 4-3 is located near the lower paper feeding device 3 and mainly guides and assists the lower piece of the carton into the path of the paper-pushing chain 4-1. By precisely controlling the speed and position of the feed roller, it can be ensured that the lower piece of the carton enters the paper-pushing device 4 with the correct posture and speed.

[0034] The paper feed rollers can be driven by a motor.

[0035] Through the coordinated operation of the upper paper pushing device 8 and the lower paper pushing device 4, the upper and lower pieces of the carton are aligned with each other during the gluing process.

[0036] The lower bonding device 5 includes a lower bonding lower conveyor belt 5-1 and a lower bonding upper conveyor belt 5-2. The lower bonding lower conveyor belt 5-1 and the lower bonding upper conveyor belt 5-2 are arranged parallel to each other and clamp the lower piece of the carton together. Through the movement of the lower bonding lower conveyor belt 5-1 and the lower bonding upper conveyor belt 5-2, the lower piece of the carton is stably transported to the designated bonding position.

[0037] The upper bonding device 9 includes an upper bonding lower conveyor belt 9-1 and an upper bonding upper conveyor belt 9-2. The upper bonding lower conveyor belt 9-1 and the upper bonding upper conveyor belt 9-2 are arranged parallel to each other and clamp the upper piece of the carton together. Through the movement of the upper bonding lower conveyor belt 9-1 and the upper bonding upper conveyor belt 9-2, the upper piece of the carton is stably transported to the designated bonding position.

[0038] The lower end of the upper bonding conveyor belt 9-2 is lower than the lower end of the upper bonding lower conveyor belt 9-1. The rear end of the lower bonding lower conveyor belt 5-1 protrudes from the rear end of the lower bonding upper conveyor belt 5-2. The lower end of the upper bonding upper conveyor belt 9-2 extends above the protruding section of the lower bonding lower conveyor belt 5-1. The lower end of the upper bonding upper conveyor belt 9-2 is adjacent to the upper end of the lower bonding lower conveyor belt 5-1. A top pulley 5-1-1 is provided on the lower side of the upper end face of the lower bonding lower conveyor belt 5-1. When the upper piece of the carton and the lower piece of the carton pass through the upper bonding device 9 and the lower bonding device 5 respectively, the upper bonding upper conveyor belt 9-2 and the lower bonding lower conveyor belt 5-1 work together to accurately and firmly bond the upper piece of the carton and the lower piece of the carton together, thereby completing the carton bonding process.
