Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, and in particular to a corrugated cardboard box gluing device. Background Technology

[0002] In corrugated cardboard box production, applying glue to the boxes is crucial to ensure their strength and airtightness. In practical applications, corrugated cardboard box glue application equipment typically requires the following technologies:

[0003] 1. Adhesive supply system, such as adhesive storage tanks and adhesive transfer pumps, can provide sufficient adhesive for application;

[0004] 2. Glue application mechanism, such as spray gun, glue roller, etc., to apply glue to the carton;

[0005] 3. Conveying mechanism, such as a conveyor belt, ensures the smooth transport of the cartons during the gluing process.

[0006] In existing glue application devices, the glue application head is usually fixed.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: When applying glue, it is necessary to manually align the area to be glued with the glue applicator before the glue can be applied to the area to be bonded. Furthermore, when making cardboard boxes, the glue needs to be applied around the edges of the corrugated paper. Therefore, the orientation of the corrugated paper needs to be changed during the operation, which is not only time-consuming and labor-intensive, but also has low glue application efficiency. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a corrugated cardboard box gluing device, which solves the problem that when applying glue, it is necessary to manually align the area to be glued with the gluing head before applying the glue to the area to be bonded. Furthermore, when making cardboard boxes, the glue needs to be applied around the edges of the corrugated paper, which requires changing the orientation of the corrugated paper during operation. This is not only time-consuming and labor-intensive, but also results in low gluing efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A corrugated cardboard box gluing device includes a workbench, a lifting frame slidably mounted on the workbench, a first stepper motor fixedly mounted on the lifting frame, rollers symmetrically rotatably mounted on the lifting frame, a conveyor belt for driving corrugated paper installed between the two rollers, a transmission pulley set for transmitting power installed between the rollers and the first stepper motor, a threaded rod rotatably mounted on the lifting frame, a second stepper motor fixedly mounted on the lifting frame, a glue spraying frame for gluing threaded onto the threaded rod, a bevel gear set for transmission installed between the second stepper motor and the glue spraying frame, and springs symmetrically mounted on the lifting frame.

[0011] Preferably, a glue storage tank for storing adhesive is fixedly installed on the workbench, and a conduit is installed between the glue storage tank and the glue spraying frame; a pipe for injecting air is opened at the top of the glue storage tank.

[0012] Preferred option: A disc motor is fixedly installed inside the glue storage tank.

[0013] Preferably, a transmission rod is fixedly installed on the shaft of the disc motor.

[0014] Preferably, a stirring rod for stirring is fixedly installed on the transmission rod.

[0015] Preferably, the top of the glue storage tank is threaded with an end cap for sealing.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In use, place one side of the corrugated paper onto the workbench and push it towards the conveyor belt. After the first stepper motor starts, it will drive the rollers to rotate through the transmission belt pulley set. The rollers will cause the conveyor belt to rotate, and the conveyor belt will then move the corrugated paper. The glue sprayer will then apply glue to the corrugated paper. If the glue application position needs to be changed during the glue application process, the second stepper motor will start and drive the threaded rod to rotate through the bevel gear set. Since the threaded rod is threadedly connected to the glue sprayer, it will cause the glue sprayer to slide, thus changing the glue application position and improving the glue application efficiency.

[0018] 2. When the air supply mechanism injects air into the glue storage tank, the air pressure inside the tank will increase, causing the glue to flow along the guide tube to the glue spraying frame. When the air supply stops, the glue will not be discharged under the action of air pressure, resulting in more uniform glue application. During use, the disc motor will start and drive the transmission rod to rotate, which in turn drives the stirring rod to rotate. The stirring rod will stir the glue, preventing sedimentation and stratification, thus improving the bonding quality. Attached Figure Description

[0025] This application provides a corrugated cardboard box gluing device, effectively solving the problems of manual alignment of the gluing head with the adhesive application area during gluing, and the need to apply the adhesive around the edges of the corrugated cardboard during box manufacturing, which is time-consuming, labor-intensive, and inefficient. In this device, one side of the corrugated cardboard is placed on the worktable and pushed onto the conveyor belt. The first step motor starts, driving the rollers via the drive belt pulley set, which in turn rotates the conveyor belt, moving the corrugated cardboard. The glue sprayer then applies the adhesive to the corrugated cardboard. During the process, if the glue application position needs to be changed, the second stepper motor starts and drives the threaded rod to rotate through the bevel gear set. Since the threaded rod is threadedly connected to the glue spraying frame, it will cause the glue spraying frame to slide, thus changing the glue application position and improving the glue application efficiency. When the air supply mechanism injects air into the glue storage tank, the air pressure inside the glue storage tank will increase, causing the glue to flow along the guide tube to the glue spraying frame. When the air supply stops, the glue will not be discharged under the action of air pressure, resulting in more uniform glue application. During use, the disc motor starts and drives the transmission rod to rotate, which in turn drives the stirring rod to rotate. The stirring rod will stir the glue, preventing the glue from settling and separating, thus improving the bonding quality. Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that when applying glue, it is necessary to manually align the area to be glued with the glue applicator before the glue can be applied to the area to be bonded. Furthermore, when making cardboard boxes, the glue needs to be applied around the edges of the corrugated cardboard, which requires changing the orientation of the corrugated cardboard during the operation. This is not only time-consuming and labor-intensive, but also results in low glue application efficiency. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a corrugated cardboard box gluing device, including a workbench 1, a lifting frame 2 slidably mounted on the workbench 1, a first stepper motor 3 fixedly mounted on the lifting frame 2, rollers 5 symmetrically rotatably mounted on the lifting frame 2, a transmission belt 6 for driving corrugated paper installed between the two rollers 5, and a transmission pulley group 4 for transmitting power installed between the rollers 5 and the first stepper motor 3.

[0028] A threaded rod 7 is rotatably mounted on the lifting frame 2. A second stepper motor 8 is fixedly mounted on the lifting frame 2. A glue spraying frame 11 for applying glue is threaded onto the threaded rod 7. A bevel gear set 9 for transmission is installed between the second stepper motor 8 and the glue spraying frame 11. Springs 13 are symmetrically mounted on the lifting frame 2. A glue storage tank 14 for storing glue liquid is fixedly mounted on the worktable 1.

[0029] A conduit 12 is installed between the glue storage tank 14 and the glue spraying frame 11; the top of the glue storage tank 14 is provided with a pipe for injecting air; a disc motor 15 is fixedly installed inside the glue storage tank 14; a transmission rod 16 is fixedly installed on the shaft of the disc motor 15; a stirring rod 17 for stirring is fixedly installed on the transmission rod 16; and an end cap 18 for sealing is threaded onto the top of the glue storage tank 14.

[0030] Workbench 1: As a basic support component, it provides a platform for the installation and operation of other components, and at the same time serves as a working platform for applying adhesive, allowing the lifting frame 2 to slide on it;

[0031] Lifting frame 2: It can slide up and down to accommodate corrugated paper of different thicknesses;

[0032] Stepper motor 3: As a power source, after starting, it transmits power to roller 5 through transmission pulley set 4;

[0033] Transmission pulley set 4: Used to transmit the power generated by the first stepper motor 3 to the roller 5;

[0034] Roller 5: Receives power from the transmission pulley group 4 and rotates, thereby driving the transmission belt 6 to work;

[0035] Conveyor belt 6: Drives the corrugated paper to move, enabling the corrugated paper to be smoothly coated with glue in the device;

[0036] Threaded rod 7: threadedly connected to the glue spraying frame 11, it drives the glue spraying frame 11 to slide when rotated, thereby changing the glue application position;

[0037] The second stepper motor 8: after starting, drives the threaded rod 7 to rotate through the bevel gear set 9, thereby adjusting the glue application position;

[0038] The bevel gear set 9 serves as a transmission between the second stepper motor 8 and the threaded rod 7, transmitting the power of the second stepper motor 8 to the threaded rod 7.

[0039] Glue spraying frame 11: A component used for applying glue, which applies the glue to the corrugated cardboard;

[0040] Conduit 12: Connects the glue storage tank 14 and the glue spraying frame 11 to transport the glue liquid;

[0041] Spring 13: enables the conveyor belt 6 on the lifting frame 2 to press the corrugated paper firmly and maintain effective friction against the corrugated paper;

[0042] Glue storage tank 14: Used to store glue liquid. The glue storage tank 14 is equipped with an air inlet pipe. When the air pressure inside the glue storage tank 14 increases, the glue liquid can be discharged.

[0043] Disc motor 15: After starting, it drives the transmission rod 16 to rotate;

[0044] Transmission rod 16: Driven to rotate by disc motor 15, which in turn drives stirring rod 17 to work;

[0045] Stirring rod 17: Stirs the adhesive solution to prevent sedimentation and stratification;

[0046] End cap 18: Seals the glue storage tank 14 to prevent glue leakage and impurities from entering, while also increasing the airtightness of the glue storage tank 14.

[0047] Working principle:

[0048] The first step is to connect the exhaust pipe at the top of the glue storage tank 14 to the air supply mechanism, and connect the first stepper motor 3, the second stepper motor 8, and the disc motor 15 to the control system. When the air supply mechanism injects air into the glue storage tank 14, the air pressure inside the glue storage tank 14 will increase, causing the glue to flow along the guide tube 12 to the glue spraying frame 11. When the air supply stops, the glue will not be discharged under the action of air pressure, that is, the glue application is more uniform. During use, the disc motor 15 will start and drive the transmission rod 16 to rotate, and the transmission rod 16 will drive the stirring rod 17 to rotate. The stirring rod 17 will stir the glue, which can prevent the glue from settling and separating, thus improving the bonding quality.

[0049] The second step involves placing one side of the corrugated paper onto the workbench 1 and pushing it towards the conveyor belt 6. After the first stepper motor 3 starts, it will drive the roller 5 to rotate through the transmission belt pulley set 4. The roller 5 will cause the conveyor belt 6 to rotate, which in turn will move the corrugated paper. Then, the glue spraying frame 11 will apply glue to the corrugated paper. If the glue application position needs to be changed during the glue application process, the second stepper motor 8 will start and drive the threaded rod 7 to rotate through the bevel gear set 9. Since the threaded rod 7 is threadedly connected to the glue spraying frame 11, it will cause the glue spraying frame 11 to slide, thereby changing the glue application position and improving the glue application efficiency.

[0050] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
