Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a carton gluing machine with an automatic glue application structure. Background Technology

[0002] Carton gluing machines are key pieces of equipment in the carton production process. They are mainly used to bond the various cardboard parts of a carton together through processes such as gluing and pressing to form a complete carton structure. They are widely used in the packaging industry, and their performance directly affects the production efficiency and product quality of cartons. In the glue application stage of traditional and existing carton gluing machines, there are often many technical defects: in existing automatic glue application equipment, the movement drive system of the glue spray head and the glue supply system are mostly set up independently, resulting in complex equipment structure, difficulty in control and coordination, and a tendency for glue supply and spraying to be out of sync. For example, insufficient glue supply during spraying causes intermittent glue application, or glue residue leakage when spraying stops causes waste, and may even lead to equipment failure. In order to improve these issues, a carton gluing machine with an automatic glue application structure is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carton gluing machine with an automatic glue application structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A carton gluing machine with an automatic glue application structure includes a vertical plate. A conveying assembly and a function box are respectively mounted on the front and back of the vertical plate. An external screw is mounted on the vertical plate via a mounting bracket. A drive motor is mounted on the mounting bracket and connected to the external screw via a rotating mechanism. A glue spray head is threadedly mounted on the external screw via a limiting mechanism. The function box contains a rotating chamber and a movable chamber. An internal screw connected to the external screw is rotatably mounted in the rotating chamber. A piston plate is located in the movable chamber and connected to the internal screw via a connecting mechanism. A glue inlet pipe and a glue outlet pipe are mounted on the function box. A glue storage cylinder is located below the function box. The glue inlet pipe is connected to the glue storage cylinder, and the glue outlet pipe is connected to the glue spray head.

[0005] Preferably, the rotating mechanism includes a first gear fixedly mounted on the output shaft of the drive motor, and a second gear meshing with the first gear is fixedly mounted on the external screw.

[0006] Preferably, the limiting mechanism includes a limiting rod fixedly mounted on the mounting bracket, the limiting rod slidingly penetrating the spray nozzle.

[0007] Preferably, the connecting mechanism includes a connecting frame threaded onto the internal screw, the end of which is fixedly connected to the piston plate.

[0008] Preferably, the inlet tube is a rigid tube, and the outlet tube is half rigid tube and half flexible tube.

[0009] Preferably, both the glue inlet pipe and the glue outlet pipe are equipped with valves, and both valves are one-way valves.

[0010] The beneficial effects of this utility model are: By using the same drive motor to simultaneously drive the outer and inner screws, the movement of the spray nozzle and the supply of glue are synchronized, simplifying the equipment structure, reducing the power source, and lowering energy consumption.

[0011] The limiting mechanism (limiting rod) ensures that the glue spray head moves stably in a straight line and avoids deviation; the one-way valve controls the unidirectional flow of glue in the glue inlet and outlet pipes to prevent backflow or glue leakage, ensure uniform glue application, and improve the quality of carton gluing.

[0012] The part connecting the glue dispensing tube to the glue spraying head is a flexible hose that can deform flexibly with the reciprocating movement of the glue spraying head without affecting the movement trajectory of the glue spraying head, thus improving the stability of equipment operation.

[0013] No manual control of the glue spray head movement and glue supply is required. The mechanical structure enables automatic glue application and replenishment, reducing manual intervention and improving production efficiency. It is suitable for batch cardboard box processing scenarios. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4A carton gluing machine with an automatic glue application structure includes a vertical plate 1. A conveying component 2 and a function box 3 are respectively installed on the front and back of the vertical plate 1, as shown in the figure. The conveying component 2 is composed of a conveying roller and a conveying belt. It is a conventional conveying component 2. The specific structure and working principle are not described in detail here.

[0018] It should be noted that for fixing the material on the conveying component 2, any mature fixing component that is compatible with the conveying component 2 in the existing technology can be selected. It is not the core technical feature of this solution, so it will not be elaborated here.

[0019] An external screw 7 is provided on the vertical plate 1 via a mounting bracket 6. A drive motor 10 is provided on the mounting bracket 6. The drive motor 10 is connected to the external screw 7 via a rotation mechanism. A glue spraying head 8 is threadedly installed on the external screw 7 via a limiting mechanism. The glue spraying head 8 is an existing technology product, and its specific structure and working principle will not be described in detail. Its rod is threadedly connected to the external screw 7.

[0020] The function box 3 has a rotating chamber 13 and a movable chamber 14 inside. The rotating chamber 13 has an inner screw 15 that is rotatably connected to the outer screw 7. The movable chamber 14 has a piston plate 16 that is connected to the inner screw 15 through a connecting mechanism. The function box 3 is equipped with a glue inlet pipe 5 and a glue outlet pipe 9. The function box 3 has a glue storage cylinder 4 at the bottom. The glue inlet pipe 5 is connected to the glue storage cylinder 4, and the glue outlet pipe 9 is connected to the glue spray head 8.

[0021] The rotating mechanism includes a first gear 11 fixedly mounted on the output shaft of the drive motor 10, and a second gear 12 fixedly mounted on the outer screw 7, meshing with the first gear 11. Relying on the first gear 11 and the second gear 12, the outer screw 7 can rotate after the drive motor 10 is started. Since the inner screw 15 is fixedly connected to the outer screw 7, the inner screw 15 will also rotate.

[0022] The limiting mechanism includes a limiting rod fixedly mounted on the mounting bracket 6, which slides through the adhesive spray head 8. The aforementioned limiting rod... Figure 4 It is shown but not labeled. It is located directly above the external screw 7 and serves to limit the spray nozzle 8, preventing it from rotating with the external screw 7.

[0023] The connecting mechanism includes a connecting frame 17 threaded onto the inner screw 15, with the end of the connecting frame 17 fixedly connected to the piston plate 16. The connecting frame 17 has a U-shaped design, with its horizontal portion sliding through the inner wall of the rotating chamber 13 and extending into the movable chamber 14. Therefore, it has its own limit and will not rotate with the inner screw 15.

[0024] The glue inlet tube 5 is a rigid tube, and the glue outlet tube 9 is half rigid and half flexible. The part that connects to the glue spray head 8 is the flexible tube, which facilitates the back-and-forth movement of the glue spray head 8.

[0025] Both the glue inlet pipe 5 and the glue outlet pipe 9 are equipped with valves, and both valves are one-way valves. The one-way valves control the unidirectional flow of glue, so that it can only be drawn into the active chamber 14 through the glue storage tank 4, and then sprayed out through the glue outlet pipe 9 and the glue spray head 8.

[0026] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0027] Working principle of this utility model: The cardboard box material to be coated with glue is conveyed by the conveying assembly 2 (composed of conveying rollers and conveyor belt) on the front of the vertical plate 1. When the material moves to below the glue spray head 8, the conveying assembly 2 stops, ready for glue application. Subsequently, the drive motor 10 starts, and its output shaft drives the first gear 11 in the rotating mechanism to rotate. The first gear 11 meshes with the second gear 12 on the outer screw 7, thereby driving the outer screw 7 to rotate. Since the inner screw 15 is fixedly connected to the outer screw 7, the inner screw 15 rotates synchronously with the outer screw 7.

[0028] When the outer screw 7 rotates, the glue spray head 8, restricted by the limiting mechanism, cannot rotate with the outer screw 7, but only moves linearly along the axis of the outer screw 7 (moving from a state close to the vertical plate 1 to a state far away from the vertical plate 1), thus realizing the moving glue spraying of the material to the designated area.

[0029] When the inner screw 15 rotates, the connecting frame 17 in the connecting mechanism does not rotate with the inner screw 15 under its own limiting action, but only moves along the axial direction of the inner screw 15, driving the piston plate 16 in the movable chamber 14 to move synchronously (from the state close to the vertical plate 1 to the state far away from the vertical plate 1); at this time, the glue in the movable chamber 14 is squeezed by the piston plate 16 and transported to the glue spraying head 8 through the glue outlet pipe 9 (the part connected to the glue spraying head 8 is a hose, which is adapted to the movement of the glue spraying head 8), and finally sprayed out by the glue spraying head 8 to the surface of the material (the one-way valve in the glue outlet pipe 9 ensures that the glue can only flow from the movable chamber 14 to the glue spraying head 8).

[0030] After the material is coated with adhesive, the conveying assembly 2 carries the material away from the spraying area; at the same time, the drive motor 10 reverses, the outer screw 7 and the inner screw 15 rotate in opposite directions, and the spraying head 8 resets along the outer screw 7 (from a state away from the vertical plate 1 to a state close to the vertical plate 1); the piston plate 16 moves in the opposite direction with the connecting frame 17 (closer to the vertical plate 1), a negative pressure is formed in the active chamber 14, and the adhesive in the glue storage cylinder 4 is sucked into the active chamber 14 through the glue inlet pipe 5 (the one-way valve in the glue inlet pipe 5 ensures that the adhesive can only flow from the glue storage cylinder 4 to the active chamber 14), completing the glue replenishment and waiting for the next spraying cycle.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
