Description

Technical Field

[0001] This utility model relates to the field of paper bag processing, and in particular to an adhesive device for paper bag processing. Background Technology

[0002] Paper bags are packaging bags made of paper. They are common household items in our daily lives. There are many types of paper bags, with a variety of paper materials and styles. According to the material, they can be divided into: white cardboard paper bags, white board paper bags, coated paper bags, kraft paper bags, and a small number made of specialty paper. Among them, bonding is the core step in turning a paper bag from a flat board into a three-dimensional container. By bonding the two ends of the board to form a cylindrical structure, and then combining it with the bottom, handles and other parts, a complete bag body can be formed.

[0003] Chinese patent CN219171820U discloses an adhesive device for paper bag processing, which can simultaneously complete the gluing and pressing of paper bags in a single operation. The operation is simple and quick, greatly saving the workload of personnel.

[0004] In the above solution, after placing the glue dispensing tube between the front and rear cardboard sides of the paper bag, the glue is applied to the opposite inner surfaces of the cardboard sides by squeezing. Then, by squeezing with two pressing rollers, the opposite inner surfaces of the cardboard sides of the paper bag are pressed together, thus completing the bonding operation. However, it is difficult to control the amount of glue dispensed by squeezing and it is impossible to ensure the continuity of glue dispensing. There is a problem that the glue may break during the bonding of the paper bag, resulting in the failure of the paper bag seal. Therefore, a bonding device for paper bag processing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an adhesive device for paper bag processing, so as to solve the problem mentioned in the background art that the glue is prone to breakage during paper bag bonding, resulting in the failure of paper bag sealing. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A bonding device for paper bag processing includes fixed plates, a first conveyor belt and a second conveyor belt disposed between the two fixed plates, as well as a first pressure roller and a second pressure roller. An adhesive application assembly is disposed above both the first and second conveyor belts. A paper bag sheet is located between the first and second conveyor belts. A support is disposed above the paper bag sheet. The support contains a limiting mechanism for restricting the position of the paper bag sheet and a guiding mechanism for guiding the paper bag sheet to move between the first and second pressure rollers. An electric telescopic rod is disposed above the support. A first driving mechanism for driving the first conveyor belt and the first pressure roller to rotate simultaneously, and a second driving mechanism for driving the second conveyor belt and the second pressure roller to rotate simultaneously, are disposed on one side of the fixed plates. The first driving mechanism is connected to the first conveyor belt and the first pressure roller via a pulley assembly, and the second driving mechanism is also connected to the first conveyor belt and the first pressure roller via a pulley assembly.

[0008] Preferably, the first drive mechanism and the second drive mechanism are a first motor and a second motor, respectively. The first motor and the second motor are both fixed on the side of the fixed plate. The first motor and the second motor are respectively connected to the shafts of the first pressure roller and the second pressure roller. The pulley assembly consists of a driving pulley and a driven pulley connected by a belt.

[0009] Preferably, the glue application assembly includes a horizontal plate, a glue application tube, a glue pump, a slide block, a lead screw, a displacement sensor, and a lead screw motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a first and second independently rotatable conveyor belt, which first rotate in the same direction to transport the paper bag sheet to the area below the support. A displacement sensor determines the position of the paper bag sheet, ensuring the guide plate is approximately positioned in the middle. Then, an electric telescopic rod drives a limiting roller to descend, pressing the paper bag sheet in place. An adhesive applicator then applies adhesive to both ends of the paper bag sheet. Next, the electric telescopic rod drives the guide plate to descend, inserting the middle of the paper bag sheet between the first and second conveyor belts. The first and second conveyor belts then rotate in opposite directions, guiding the middle of the paper bag sheet between the first and second pressure rollers. Simultaneously, the electric telescopic rod drives the guide plate and limiting roller to rise, pressing the adhesive application points at both ends of the paper bag sheet together between the first and second pressure rollers, thus completing the paper bag sheet bonding process. The adhesive pump controls the adhesive output, and a lead screw drives the adhesive tube to move stably, preventing adhesive interruptions. Furthermore, the first and second conveyor belts transport the paper bag sheet, and the paper bag sheet is held between them, improving the stability of subsequent pressing and preventing misalignment.

[0018] Please see Figure 1-4 In this utility model, an adhesive device for paper bag processing includes a fixed plate 1. The device is characterized by: a first conveyor belt 4 and a second conveyor belt 5, a first pressure roller 8 and a second pressure roller 9, arranged between the two fixed plates 1; an adhesive application assembly 2 is arranged above both the first conveyor belt 4 and the second conveyor belt 5; a paper bag board is located between the first conveyor belt 4 and the second conveyor belt 5; a support 3 is arranged above the paper bag board; an electric telescopic rod 304 is arranged above the support 3; a first motor 6 and a second motor 7 are arranged on one side of the fixed plate 1; the first motor 6 is connected to the first conveyor belt 4 and the first pressure roller 8 via a pulley assembly 10; and the second motor 7 is connected to the first conveyor belt 4 and the first pressure roller 8 via the pulley assembly 10.

[0019] The first conveyor belt 4 and the second conveyor belt 5 are both wrapped into a triangle, and their sides are in a close fit. The close fit surfaces of the first conveyor belt 4 and the second conveyor belt 5 pass between the first pressure roller 8 and the second pressure roller 9. The two ends of the first pressure roller 8 and the second pressure roller 9 are respectively connected to the bearings of the two fixed plates 1.

[0020] Example 1: Please refer to Figure 1-4 In this embodiment of the utility model, an adhesive device for paper bag processing is provided, in which a first motor 6 and a second motor 7 are both fixed on the side of a fixing plate 1, and the first motor 6 and the second motor 7 are respectively connected to the shafts of the first pressure roller 8 and the second pressure roller 9. The pulley assembly 10 consists of a driving wheel and a driven wheel connected by a belt.

[0021] The lead screw 205 and displacement sensor 206 are respectively installed on the top and bottom of the horizontal plate 201. The slide 204 is installed on the lead screw 205. The glue pump 203 is fixed on the slide 204. The lead screw motor 207 is connected to one end of the lead screw 205.

[0022] The bracket 3 has an inverted U-shaped structure. The bracket 3 has a connecting plate 301 inside and a slide rail 302 on its inner side. The connecting plate 301 and the slide rail 302 are connected by a slider. The piston rod inside the electric telescopic rod 304 is connected to the top of the connecting plate 301. The guiding mechanism is a guide plate 303, which is fixed below the connecting plate 301. The guide post 306 passes through the connecting plate 301. The upper end of the guide post 306 is connected to the stop block 309, and the lower end of the guide post 306 is connected to the shaft of the limiting roller 305. The retaining ring 308 is fixed on the surface of the guide post 306. The spring 307 is sleeved on the guide post 306 and is located between the connecting plate 301 and the retaining ring 308.

[0023] When the first motor 6 and the second motor 7 drive the first conveyor belt 4 and the second conveyor belt 5 to rotate in the same direction, the paper bag board is transported to the bottom of the support 3. The displacement sensor 206 determines the moving position of the paper bag board, so that the guide plate 303 is located in the middle of the paper bag board. Then, the electric telescopic rod 304 first drives the limiting roller 305 to descend and press the paper bag board. The glue application assembly 2 then applies glue to both ends of the paper bag board. Then, the electric telescopic rod 304 drives the guide plate 303 to descend, so that the middle of the paper bag board is inserted between the first conveyor belt 4 and the second conveyor belt 5. After that, the first conveyor belt 4 and the second conveyor belt 5 rotate in opposite directions and guide the middle of the paper bag board into the middle between the first pressure roller 8 and the second pressure roller 9. At the same time, the electric telescopic rod 304 drives the guide plate 303 and the limiting roller 305 to rise, and the glue application positions at both ends of the paper bag board move to the middle between the first pressure roller 8 and the second pressure roller 9 for pressing, thereby completing the paper bag board bonding operation. Finally, the paper bag board is discharged from the lower end between the first pressure roller 8 and the second pressure roller 9, thus realizing automated paper bag bonding and improving production efficiency.

[0024] The glue pump 203 controls the glue dispensing amount, and the screw motor 207 drives the glue tube 202 to move stably through the screw 205, thus avoiding glue interruption. In addition, the first conveyor belt 4 and the second conveyor belt 5 can not only transport the paper bag board, but also clamp the paper bag board between the first conveyor belt 4 and the second conveyor belt 5, which improves the stability of the glue application and pressing at both ends of the paper bag board, avoids misalignment, and further improves the accuracy of paper bag bonding.

[0025] The working principle of this utility model is as follows: the paper bag board is transported to the bottom of the support 3 by the first conveyor belt 4 and the second conveyor belt 5 rotating in the same direction. The displacement sensor 206 determines the moving position of the paper bag board, so that the guide plate 303 is located above the middle of the paper bag board. Then, the limiting roller 305 descends to press the paper bag board. The glue application component 2 then applies glue to both ends of the paper bag board. Then, the electric telescopic rod 304 drives the guide plate 303 to descend, so that the middle of the paper bag board is inserted between the first conveyor belt 4 and the second conveyor belt 5. Then, the first conveyor belt 4 and the second conveyor belt 5 rotate in opposite directions and guide the middle of the paper bag board into the space between the first pressure roller 8 and the second pressure roller 9. At the same time, the electric telescopic rod 304 drives the guide plate 303 and the limiting roller 305 to rise, and the glue application positions at both ends of the paper bag board move to the space between the first pressure roller 8 and the second pressure roller 9 for pressing, thereby completing the paper bag board bonding operation. Finally, the paper bag board is discharged from the lower end between the first pressure roller 8 and the second pressure roller 9.
