[0005] In the above solution, by arranging a guiding plate at the connection between the conveyor belt of the automatic box gluing machine and the stacking basket, it is easier for the paper boxes to enter the stacking basket. However, the way the paper boxes fall on the guiding plate completely relies on gravity to slide. Some paper boxes with smaller volume and gravity will easily accumulate on the guiding plate, thus affecting the rate of paper box collection. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an automatic box gluing machine to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An automatic box gluing machine includes a box gluing machine body, a conveyor belt and a stacking frame. The conveyor belt is fixedly installed on one side of the conveyor belt support. The stacking frame is located on one side of the conveyor belt. A guiding plate is arranged inside the conveyor belt support. Both sides of the guiding plate are fixedly connected with rotating rods. One side of the rotating rod extends to one side of the conveyor belt support and is fixedly connected with a rotating block;

[0009] A swinging mechanism is fixedly arranged on the conveyor belt support and can control the guiding plate to swing around the rotating rod;

[0010] The jetting mechanism is fixedly arranged on the swinging mechanism and can collect gas while the swinging mechanism controls the swinging of the guiding plate, and then jet it onto the guiding plate.

[0011] Preferably, the swinging mechanism includes a mounting plate fixedly arranged on the conveyor belt support. A motor is fixedly connected to the top of the mounting plate. The output end of the motor is fixedly connected to a reciprocating lead screw. A moving block is drivingly connected to the surface of the reciprocating lead screw.

[0013] Preferably, a piston is fixedly connected to the bottom of the pushing block. The piston is made of rubber.

[0014] Preferably, sliding blocks are fixedly connected to both sides of the moving block. Sliding grooves matched with the sliding blocks are arranged on the inner wall of the conveyor belt support.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By setting the swinging mechanism, the present utility model can start the motor while the paper box falls from the conveyor belt onto the guiding plate. The motor drives the reciprocating lead screw to rotate. While the reciprocating lead screw rotates, it drives the moving block, so that the moving block moves up and down along the trajectories of the sliding blocks and the sliding grooves. The moving block drives the traction frames and the traction rod to move up and down reciprocally. The surface of the traction rod contacts the inner wall of the extrusion groove, and the traction block and the guiding plate are swung around the rotating rod by extrusion, improving the fluidity of the paper boxes on the guiding plate, and further improving the collection rate of the paper boxes.

[0019] 2. By providing a jetting mechanism, the utility model can drive the push rod and the push block to move downward during the downward movement of the moving block. The push block drives the piston to move downward, compressing the gas inside the air collecting cylinder. When the air pressure inside the air collecting cylinder exceeds the limit of the one-way pressure valve, the gas will enter the inside of the nozzle through the transmission pipe, and then be sprayed to both sides of the guiding plate by the nozzle. Then, when the moving block moves upward, it will drive the push rod and the push block to move upward, and the push block will drive the piston to move upward. At this time, a negative pressure is formed inside the air collecting cylinder, and the gas will enter the inside of the air collecting cylinder through the air inlet pipe, and so on in a cycle, improving the falling speed of the paper box by the impact of the air flow.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0028] Please refer to Figures 1-6 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] An automatic folder gluing machine, comprising a folder gluing machine body 1, a conveyor belt 2 and a stacking frame 3, wherein the conveyor belt 2 is fixedly mounted on one side of the conveyor belt 2, the stacking frame 3 is located on one side of the conveyor belt 2, a guide plate 4 is arranged inside a bracket of the conveyor belt 2, both sides of the guide plate 4 are fixedly connected with a rotating rod 5, one side of the rotating rod 5 is connected to one side of the bracket of the conveyor belt 2, and a rotating block 6 is fixedly connected thereto;

[0031] The swing mechanism is fixedly arranged on the support of the conveyor belt 2 and can control the guide plate 4 to swing around the rotating rod 5;

[0032] The gushing mechanism is fixedly arranged on the swinging mechanism, and can collect gas while the swinging mechanism controls the guide plate 4 to swing, and then gush gas on the guide plate 4.

[0033] One implementation of the present embodiment 1 is: the swing mechanism includes a placement plate 7 fixedly arranged on the support of the conveyor belt 2, the top of the placement plate 7 is fixedly connected to a motor 8, the output end of the motor 8 is fixedly connected to a reciprocating screw 9, the surface of the reciprocating screw 9 is transmission-connected to a moving block 10, one side of the moving block 10 is fixedly connected to two traction frames 11, one side of the traction frame 11 is connected to a traction rod 12, the surface of the traction rod 12 is sleeved with a traction block 13, and one side of the traction block 13 is fixedly connected to one side of the guide plate 4.

[0034] In this embodiment, considering the way in which the paper boxes fall on the guide plate 4, they completely rely on gravity to slide down. Some paper boxes with smaller volume and gravity will easily accumulate on the guide plate 4, thereby affecting the rate of paper box collection. Therefore, by setting a swing mechanism, the motor 8 can be started when the paper boxes fall on the guide plate 4 from the conveyor belt 2. The motor 8 will drive the reciprocating screw 9 to rotate. When the reciprocating screw 9 rotates, it will drive the moving block 10 to move up and down along the trajectory of the sliding block 21 and the sliding groove 22. The moving block 10 will drive the traction frame 11 and the traction rod 12 to move up and down reciprocatingly. The surface of the traction rod 12 will contact the inner wall of the extrusion groove 23. The traction block 13 and the guide plate 4 are swung around the rotating rod 5 by extrusion, thereby improving the fluidity of the paper boxes on the guide plate 4, thereby improving the rate of paper box collection.

[0035] The problem is that, considering the way in which the paper boxes fall on the guide plate 4 and slide down completely by gravity, some paper boxes with smaller volume and gravity will easily accumulate on the guide plate 4, thereby affecting the collection rate of the paper boxes.

[0036] Preferably, sliding blocks 21 are fixedly connected to both sides of the moving block 10 , and a sliding groove 22 for use with the sliding block 21 is provided on the inner wall of the support of the conveyor belt 2 .

[0037] In this embodiment, by providing the sliding block 21 and the sliding groove 22, when the reciprocating lead screw 9 drives the moving block 10, the moving block 10 can be restricted to move up and down only along the trajectories of the sliding block 21 and the sliding groove 22, while improving the fixing stability during its movement.

[0038] Preferably, an extrusion groove 23 is formed on one side of the traction block 13, and the extrusion groove 23 is used in cooperation with the traction rod 12.

[0039] In this embodiment, by providing the extrusion groove 23, when the traction rod 12 moves downward, a moving space can be left for the traction rod 12 to avoid the phenomenon of jamming.

[0040] Preferably, a torsion spring 24 is sleeved on the surface of the rotating rod 5. One end of the torsion spring 24 is fixedly connected to one side of the rotating block 6, and the other end of the torsion spring 24 is fixedly connected to one side of the support of the conveyor belt 2.

[0041] In this embodiment, by providing the torsion spring 24, it can play a supporting role for the rotating rod 5, the rotating block 6 and the guiding plate 4, so that the guiding plate 4 always maintains an inclined state, facilitating the normal falling of the carton.

[0042] Embodiment Two:

[0043] On the basis of Embodiment One, in this embodiment, the swinging mechanism can make the guiding plate 4 swing around the rotating rod 5, thereby increasing the falling speed of the carton in the paper box. However, considering that during the swinging process of the guiding plate 4, some paper boxes will move to both sides of the inner wall of the guiding plate 4 and are also prone to accumulation, affecting the falling speed. In this application, the spraying mechanism includes two air collecting cylinders 14 fixedly connected to the top of the placement plate 7. One side of the air collecting cylinder 14 is fixedly connected to an air inlet pipe 15 through a one-way valve, and the other side of the air collecting cylinder 14 is fixedly connected to a transmission pipe 16. One end of the transmission pipe 16 is fixedly connected to a nozzle 17 through a one-way pressure valve. A pushing block 18 is arranged inside the air collecting cylinder 14. The top of the pushing block 18 is fixedly connected to a pushing rod 19. The top of the pushing rod 19 penetrates to the top of the air collecting cylinder 14 and is fixedly connected to the bottom of the moving block 10.

[0044] In this embodiment, considering that during the swinging process of the guiding plate 4, some paper boxes will move to both sides of the inner wall of the guiding plate 4 and are prone to accumulation, which will affect the falling rate. Therefore, by setting a spraying mechanism, during the downward movement of the moving block 10, the push rod 19 and the push block 18 can be driven to move downward. The push block 18 drives the piston 20 to move downward, compressing the gas inside the air collecting cylinder 14. When the air pressure in the air collecting cylinder 14 exceeds the limit of the one-way pressure valve, the gas will enter the inside of the nozzle 17 through the transmission pipe 16 and then be sprayed from the nozzle 17 to both sides of the guiding plate 4. Then, when the moving block 10 moves upward, it will drive the push rod 19 and the push block 18 to move upward, and the push block 18 will drive the piston 20 to move upward. At this time, the inside of the air collecting cylinder 14 is in a negative pressure state, and the gas will enter the inside of the air collecting cylinder 14 through the air inlet pipe 15. This cycle is repeated, and the falling rate of the paper boxes is increased by the impact of the airflow;

[0045] It solves the problem that considering that during the swinging process of the guiding plate 4, some paper boxes will move to both sides of the inner wall of the guiding plate 4 and are prone to accumulation, which affects the falling rate;

[0046] It should be noted that the one-way valve is a valve that can only allow air to enter the air collecting cylinder 14, and the one-way pressure valve is a valve that can only allow air to exit the nozzle 17.

[0047] Preferably, the bottom of the push block 18 is fixedly connected to the piston 20, and the material of the piston 20 is rubber.

[0048] In this embodiment, by setting the piston 20, a sealed cavity can be formed inside the air collecting cylinder 14, facilitating the movement of the piston 20 to complete the processes of air collection and air spraying.

[0049] Working principle: When the paper box falls on the guiding plate 4 from the conveyor belt 2, the motor 8 is started. The motor 8 drives the reciprocating lead screw 9 to rotate. While the reciprocating lead screw 9 rotates, it drives the moving block 10, causing the moving block 10 to move up and down along the trajectories of the sliding block 21 and the sliding groove 22. The moving block 10 drives the traction frame 11 and the traction rod 12 to move up and down reciprocally. The surface of the traction rod 12 contacts the inner wall of the extrusion groove 23, and the traction block 13 and the guiding plate 4 are swung around the rotating rod 5 by extrusion, improving the fluidity of the paper boxes on the guiding plate 4 and thus increasing the rate of paper box collection;

[0050] During the downward movement of the moving block 10, the push rod 19 and the push block 18 are driven to move downward. The push block 18 drives the piston 20 to move downward, compressing the gas inside the air collecting cylinder 14. When the air pressure inside the air collecting cylinder 14 exceeds the limit of the one-way pressure valve, the gas will enter the inside of the nozzle 17 through the transmission pipe 16, and then be sprayed from the nozzle 17 to both sides of the guiding plate 4. Then, when the moving block 10 moves upward, the push rod 19 and the push block 18 will be driven to move upward, and the push block 18 will drive the piston 20 to move upward. At this time, the inside of the air collecting cylinder 14 is in a negative pressure state, and the gas will enter the inside of the air collecting cylinder 14 through the air inlet pipe 15. This cycle is repeated to increase the falling speed of the paper box by the impact of the airflow.

[0051] It should be noted that the motor is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Moreover, the specific composition and principle of the power supply of the motor are clear to those skilled in the art, so it will not be elaborated in detail here.

[0052] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
