Description

Technical Field

[0001] This utility model belongs to the technical field of automatic box gluing machines, specifically an adjustable gluing device for an automatic box gluing machine. Background Technology

[0002] An automatic carton gluing machine is an automated piece of equipment used in carton production. It folds, applies glue, and bonds corrugated cardboard into cartons, achieving fully automated operation from paper feeding and gluing to folding and bonding. It boasts advantages such as high production efficiency, stable quality, and labor savings, and is widely used in the carton packaging industry. Automatic carton gluing machines are typically equipped with a gluing device. Existing automatic carton gluing machines generally replenish glue by allowing it to fall naturally due to gravity. However, because glue is viscous and has poor flowability, relying solely on gravity for replenishment is inefficient. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an adjustable gluing device for an automatic box gluing machine. It solves the problem that existing automatic box gluing machines generally rely on the gravity of the glue to make it fall naturally when replenishing glue. However, due to the viscosity and poor fluidity of the glue, relying solely on the gravity of the glue for replenishment results in low work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable gluing device for an automatic box gluing machine, comprising a glue coating box, a glue storage cylinder fixedly connected to the top of the glue coating box, a cover plate fixedly connected to the top of the glue storage cylinder, a fixing plate fixedly connected to the top of the cover plate, a motor fixedly connected to the fixing plate, a gear fixedly connected to the output end of the motor, a rack meshing on the gear, a moving plate fixedly connected to the bottom of the rack, and a rubber piston fixedly connected to the bottom of the moving plate; The bottom of the glue storage cylinder is fixedly connected to the discharge pipe, and the glue storage cylinder is fixedly connected to the feed pipe. The feed pipe, the glue storage cylinder and the discharge pipe are connected. The feed pipe is threaded and has an internal threaded cover threaded to it. The cover plate has a rectangular groove, and four rotating shafts are rotatably connected inside the rectangular groove. One end of each rotating shaft is fixedly connected to a limit plate. The number of limiting plates is four, and a roller is fixedly connected between two limiting plates. Two connecting strips are fixedly connected to the rack, and the connecting strips are located between the two limiting plates. A second motor is fixedly connected to the glue-applying box, and a rotating rod is fixedly connected to the output end of the second motor. A glue-applying wheel is fixedly connected to one end of the rotating rod.

[0005] As a further embodiment of this utility model: a second motor is fixedly connected to the glue coating box, and a support plate is fixedly connected to the glue coating box, with the support plate located at the bottom of the second motor.

[0006] As a further embodiment of this utility model: a rotating rod is fixedly connected to the output end of the second motor, a partition is fixedly connected inside the glue coating box, and the rotating rod is rotatably connected to the partition through a bearing.

[0007] As a further embodiment of this utility model: one end of the rotating rod is fixedly connected to a glue-applying wheel, the top of the glue-applying box is fixedly connected to a frame, and a lead screw is rotatably connected to the frame via a bearing.

[0008] As a further embodiment of this utility model: a connecting plate is threaded onto the lead screw, the connecting plate is located inside the frame, a lifting plate is fixedly connected to the connecting plate, and a U-shaped plate is fixedly connected to the bottom of the lifting plate.

[0009] As a further embodiment of this utility model: a pressure roller is rotatably connected to the U-shaped plate, and a knob is fixedly connected to the top of the lead screw, with several grooves provided on the knob.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The adjustable gluing device of this automatic carton gluing machine consists of a rubber piston, an internal threaded cap, a feed pipe, gears, a rack, a motor, rollers, and a limit plate. In use, the internal threaded cap is unscrewed, and glue is added through the feed pipe into the glue storage tank for storage. After the glue is added, the internal threaded cap is tightened. When it is necessary to replenish glue into the gluing tank, the motor is started, driving the gears to rotate. Because the gears mesh with the rack, when the gears rotate, the rack, the moving plate, and the rubber piston move downwards. As the rubber piston moves downwards, the stored glue is added. The glue inside the cylinder is pushed, allowing it to enter the glue-applying box through the discharge pipe, thus replenishing the glue. At the same time, the connecting strip moves between two limiting plates. The limiting plates limit the movement of the connecting strip, improving the smoothness of its movement with the rack. The rollers convert sliding friction into rolling friction, reducing friction and improving the smoothness of the connecting strip's movement. Furthermore, the rubber piston moves down to push the glue for feeding, assisting in glue replenishment and improving work efficiency. 2. The adjustable gluing device of this automatic carton gluing machine, through the setting of a pressure roller, a coating roller, a second motor, and a lead screw, allows for adjustment of the distance between the pressure roller and the coating roller. Turning the knob drives the lead screw to rotate. Since the connecting plate is threaded onto the lead screw, its rotation causes the connecting plate, lifting plate, U-shaped plate, and pressure roller to move up and down, thus adjusting the distance between them. When gluing the cardboard, the second motor is started, driving the rotating rod and coating roller to rotate. The coating roller applies glue from the inside of the coating box. When the conveyor transports the cardboard between the pressure roller and the coating roller, the high-speed rotating coating roller applies glue to the cardboard. This device can adjust the distance between the pressure roller and the coating roller according to the cardboard thickness, accommodating cardboard of different thicknesses and thus expanding its application range.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-5As shown, this utility model provides a technical solution: an adjustable gluing device for an automatic box gluing machine, including a glue coating box 1, a glue storage cylinder 2 fixedly connected to the top of the glue coating box 1, a cover plate 3 fixedly connected to the top of the glue storage cylinder 2, a fixing plate 7 fixedly connected to the top of the cover plate 3, a motor 8 fixedly connected to the fixing plate 7, a gear 9 fixedly connected to the output end of the motor 8, a rack 10 meshing with the gear 9, a motor 26 fixedly connected to the glue coating box 1, and a support plate 25 fixedly connected to the glue coating box 1, with the support plate 25 located at the bottom of the motor 26.

[0014] A movable plate 11 is fixedly connected to the bottom of the rack 10, and a rubber piston 12 is fixedly connected to the bottom of the movable plate 11. A discharge pipe 13 is fixedly connected to the bottom of the glue storage cylinder 2, and a feed pipe 5 is fixedly connected to the glue storage cylinder 2. The feed pipe 5, the glue storage cylinder 2, and the discharge pipe 13 are connected in communication. The feed pipe 5 is threaded, and an internal threaded cap 6 is threadedly connected to the feed pipe 5. Because of the internal threaded cap 6, the threaded connection has good sealing performance. When the rubber piston 12 moves down, it will compress the air inside the glue storage cylinder 2. The internal threaded cap 6 seals the feed pipe 5 to prevent glue from being discharged from the feed pipe 5. A rotating rod 27 is fixedly connected to the output end of the motor 26. A partition 29 is fixedly connected inside the glue application box 1. Because of the partition 29, the partition 29 can support and limit the rotation of the rotating rod 27, thereby improving the stability of the rotation of the rotating rod 27. The rotating rod 27 is rotatably connected to the partition 29 through a bearing.

[0015] A rectangular groove 18 is provided on the cover plate 3. Four rotating shafts 15 are rotatably connected inside the rectangular groove 18. One end of the rotating shaft 15 is fixedly connected to a limiting plate 16. Because of the limiting plate 16, when the connecting strip 14 moves between two limiting plates 16, the limiting plate 16 can limit the connecting strip 14, thereby improving the smoothness of the movement of the connecting strip 14 and the rack 10. There are four limiting plates 16. A roller 17 is fixedly connected between two limiting plates 16. Two connecting strips 14 are fixedly connected to the rack 10. One end of the rotating rod 27 is fixedly connected to a glue-applying wheel 28. A frame 4 is fixedly connected to the top of the glue-applying box 1. A lead screw 19 is rotatably connected to the frame 4 through a bearing.

[0016] The connecting strip 14 is located between the two limiting plates 16. The connecting plate 20 is threaded onto the lead screw 19. The connecting plate 20 is located inside the frame 4. The lifting plate 21 is fixedly connected to the connecting plate 20. The bottom of the lifting plate 21 is fixedly connected to the U-shaped plate 22. The pressure roller 23 is rotatably connected to the U-shaped plate 22. The top of the lead screw 19 is fixedly connected to the knob 24. The knob 24 has several grooves. Because the knob 24 has several grooves, it can increase friction, making it easier for personnel to turn the knob 24 and improving the ease of operation.

[0017] The working principle of this utility model is as follows: In use, unscrew the inner threaded cap 6 and add the glue into the glue storage cylinder 2 through the feed pipe 5 for storage. After the glue is added, tighten the inner threaded cap 6. When it is necessary to replenish the glue into the glue application box 1, start the motor 8 to drive the gear 9 to rotate. Since the gear 9 meshes with the rack 10, when the gear 9 rotates, the rack 10, the moving plate 11 and the rubber piston 12 will move down. When the rubber piston 12 moves down, it pushes the glue inside the glue storage cylinder 2, so that the glue enters the glue application box 1 through the discharge pipe 13 to complete the glue replenishment. At the same time, the connecting bar 14 will move between the two limit plates 16. When it is necessary to adjust the distance between the pressure roller 23 and the coating roller 28, turn the knob 24 to drive the lead screw 19 to rotate. Since the connecting plate 20 is threaded onto the lead screw 19, when the lead screw 19 rotates, it can drive the connecting plate 20, the lifting plate 21, the U-shaped plate 22 and the pressure roller 23 to move up and down, thereby adjusting the distance between the pressure roller 23 and the coating roller 28. When it is necessary to apply glue to the cardboard, start the motor 26 to drive the rotating rod 27 and the coating roller 28 to rotate. The coating roller 28 will apply glue to the inside of the coating box 1. When the conveying device transports the cardboard between the pressure roller 23 and the coating roller 28, the cardboard can be glued by the high-speed rotating coating roller 28.
