Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a fully automatic carton stacking conveyor. Background Technology

[0002] Fully automatic cardboard box stacking and conveyor systems are primarily used for the efficient stacking and transport of cardboard boxes, helping businesses improve logistics efficiency and optimize warehouse space utilization. This equipment can quickly and neatly stack large quantities of cardboard boxes and accurately transport them to designated locations. It is widely used in various manufacturing enterprises, logistics centers, and warehouses. In practical applications, fully automatic cardboard box stacking and conveyor systems typically require the following technologies:

[0003] 1. Conveyor control technology ensures smooth and accurate delivery of cartons;

[0004] 2. The robust and durable housing is designed to withstand prolonged high-intensity work.

[0005] 3. Control system: timely control of the start and stop of the conveying device.

[0006] Currently, various equipment and methods are used to achieve fully automated stacking and conveying of cardboard boxes.

[0007] For example, a Chinese patent discloses: A cardboard sheet stacking device for cardboard box processing, patent number: CN222361132U, which sets a compaction component including a cylinder and a pressure plate on the top of the stacking box. When the cardboard sheets are stacked in the stacking box, the cylinder can be activated to drive the pressure plate to compact multiple cardboard sheets, reduce the volume, and facilitate subsequent bundling and transfer.

[0008] However, the above method has a prominent problem: after the stacking and compression work is completed, the device lacks a limiting mechanism for compressing the cardboard boxes. Since the raw materials of the cardboard boxes usually have a certain degree of elasticity, the internal fiber structure will tend to return to its original shape after compression. Without a limiting mechanism, it is impossible to effectively prevent the cardboard boxes from rebounding, resulting in unstable compression effect, which is not conducive to subsequent bundling, packaging and other operations. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a fully automatic cardboard box stacking and conveying machine. It solves the problem that after the device completes the stacking and compression process, there is a lack of a limiting mechanism for the compressed cardboard boxes. Since the raw materials of cardboard boxes usually have a certain degree of elasticity, the internal fiber structure tends to return to its original shape after compression. The lack of a limiting mechanism cannot effectively prevent the cardboard boxes from rebounding, resulting in unstable compression effect and hindering subsequent bundling, packaging and other operations.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An automatic cardboard box stacking and conveying machine includes a palletizing box, a U-shaped frame slidably connected inside the palletizing box, a limit post rotatably connected inside the U-shaped frame, a torsion spring sleeved on the outer surface of the limit post, a round rod fixedly connected to the outer surface of the palletizing box, the limit post and the round rod fitting together, and a cylinder fixedly connected to the upper end of the palletizing box, the cylinder and the limit post being on the same vertical line.

[0012] Preferably, a compression plate is fixedly connected to the lower end of the cylinder, and the compression plate is slidably connected inside the palletizing box.

[0013] Preferably, the palletizing box has a rectangular chute inside, the U-shaped frame is slidably connected inside the rectangular chute, and the conveyor body is fixedly connected to the outer surface of the palletizing box.

[0014] Preferably, a drive motor is fixedly connected to the outer surface of the conveyor body, and a brush roller is rotatably connected inside the conveyor body, with the brush roller sleeved on the outer surface of the drive motor.

[0015] Preferably, the conveyor body has a conveyor belt assembly inside, the conveyor belt assembly and the palletizing box are on the same horizontal line, and a control box is fixedly connected to the outer surface of the conveyor body.

[0016] Preferably, the palletizing box has a threaded rod inside, which is rotatably connected inside the U-shaped frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the cardboard box material falls along the inside of the palletizing box, it will contact the inclined surface of the limiting post and squeeze it to rotate. When the limiting post rotates, it squeezes the torsion spring to contract. After the cardboard box material falls, the limiting post is pushed back to its original position by the force of the torsion spring. If the compression plate does not rise to its original position after the cardboard box material is compressed, turning the threaded rod can drive the U-shaped frame to slide downward to limit the compressed cardboard box material, so as to avoid the cardboard box material from rebounding and resetting after compression, further reducing its volume and improving the convenience of transportation operations.

[0019] 2. During the conveying operation, place the carton material on the conveyor belt assembly, press the control box to start the conveyor belt assembly, and the conveyor belt assembly will transport the carton material to one end close to the palletizing box. After being transported, the carton material falls into the palletizing box along the inclined feed port, so as to realize the fully automatic stacking and conveying operation, realize the continuous and automated conveying and stacking process, reduce manual intervention and operation time, and greatly improve the overall work efficiency.

[0026] This application provides a fully automatic cardboard box stacking and conveying machine, which effectively solves the problem of the lack of a limiting mechanism for compressed cardboard boxes after stacking and compression. Since cardboard raw materials typically have a certain degree of elasticity, the internal fiber structure tends to return to its original shape after compression. The lack of a limiting mechanism cannot effectively prevent this rebound, leading to unstable compression and hindering subsequent bundling and packaging operations. When the cardboard material falls along the inside of the stacking box, it contacts the inclined surface of the limiting post and compresses it, causing it to rotate. The rotating limiting post compresses the torsion spring, causing it to contract. After the cardboard material falls, the torsion spring pushes the limiting post back to its original position. If the compression plate does not rise to its original position after compression, turning the threaded rod can drive the U-shaped frame to slide downwards to limit the compressed cardboard material, preventing rebound and further reducing its volume and improving the convenience of transportation operations. Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that after the device completes the stacking and compression process, there is a lack of a limiting mechanism for the compressed cartons. Since the raw materials of cartons usually have a certain degree of elasticity, the internal fiber structure tends to return to its original shape after compression. The lack of a limiting mechanism cannot effectively prevent the cartons from rebounding, resulting in unstable compression and hindering subsequent bundling and packaging operations. The overall concept is as follows: A fully automatic carton stacking conveyor includes a stacking box 11, a U-shaped frame 12 slidably connected inside the stacking box 11, a limiting post 13 rotatably connected inside the U-shaped frame 12, a torsion spring 14 sleeved on the outer surface of the limiting post 13, and a fixed connection to the outer surface of the stacking box 11. The round rod 15 and the limiting post 13 are attached to each other. After being conveyed, the cardboard material falls into the palletizing box 11 through the inclined feed port. When the cardboard material falls into the inside of the palletizing box 11, it contacts the inclined surface of the limiting post 13 and squeezes it to rotate. The rotation of the limiting post 13 compresses the torsion spring 14 and causes it to retract. After the cardboard material falls, the limiting post 13 exerts its compressive force, which is pushed back to its original position by the force of the torsion spring 14. The round rod 15 connected to the surface of the U-shaped frame 12 can limit and control the limiting post 13, so that it can only rotate in one direction. By limiting the cardboard material after compression, the limiting post 13 ensures the tightness of the bundling operation and further reduces its volume. A cylinder 16 is fixedly connected to the upper end of the palletizing box 11. The cylinder 16 and the limiting post 13 are on the same vertical line. A threaded rod 25 is threadedly connected inside the palletizing box 11. The threaded rod 25 is rotatably connected inside the U-shaped frame 12. By gripping and turning the threaded rod 25, which is threaded into the palletizing box 11, the U-shaped frame 12 can be slidably adjusted to change its placement height, adapting to different palletizing height requirements. After the cardboard box material is compressed and bundled, turning the threaded rod 25 pulls the U-shaped frame 12 upwards, allowing the cardboard box material to be retrieved and transported. A compression plate 17 is fixedly connected to the lower end of the cylinder 16. The compression plate 17 is slidably connected inside the palletizing box 11. After the material is loaded and palletized, the cylinder 16 is activated, and the output shaft of the cylinder 16 pushes the compression plate downwards. 17 Slides, the compression plate 17 slides and squeezes the carton material to compress it, saving its volume. The compression plate 17 is located between the two limiting posts 13 and does not contact them. When the carton material falls along the inside of the palletizing box 11, it will contact the inclined surface of the limiting post 13 and squeeze it to rotate. When the limiting post 13 rotates, it squeezes the torsion spring 14 to make it contract. When the carton material falls, it loses the squeezing force on the limiting post 13. Under the action of the torsion spring 14, it pushes the limiting post 13 to reset. The round rod 15 connected to the surface of the U-shaped frame 12 can limit the limiting post 13. When the compression plate 17 has not risen to reset after the carton material is compressed, turning the threaded rod 25 can drive the U-shaped frame 12 to slide downward to limit the compressed carton material.

[0028] The palletizing box 11 has a rectangular slide groove 18 inside, and a U-shaped frame 12 is slidably connected inside the rectangular slide groove 18. The U-shaped frame 12 slides within the rectangular slide groove 18 to ensure its sliding trajectory. A conveyor body 19 is fixedly connected to the outer surface of the palletizing box 11, and a drive motor 21 is fixedly connected to the outer surface of the conveyor body 19. A brush roller 22 is rotatably connected inside the conveyor body 19 and is sleeved on the outer surface of the drive motor 21. During the conveying process, the drive motor 21 is started, and the output shaft of the drive motor 21 drives the brush roller 22 to rotate, wiping and cleaning the surface of the cardboard material. After the material is loaded and palletized, the cylinder 16 is started, and the output shaft of the cylinder 16 pushes the compression plate 17 downward to press the palletizing box. The internal sliding mechanism of the pallet box 11 allows the compression plate 17 to slide and compress the cardboard material, saving space. The compression plate 17 is located between the two limiting posts 13 and does not contact them. The inside of the pallet box 11 is provided with a rectangular slide groove 18, and the U-shaped frame 12 is slidably connected inside the rectangular slide groove 18, ensuring the sliding trajectory of the U-shaped frame 12. By holding and turning the threaded rod 25, since the threaded rod 25 is threadedly connected inside the pallet box 11, turning the threaded rod 25 can drive the U-shaped frame 12 to slide, thereby adjusting its placement height to meet the palletizing needs of different heights. After the cardboard material is compressed and bundled, turning the threaded rod 25 pulls the U-shaped frame 12 upward, and the cardboard material can be picked up and transported.

[0029] The conveyor body 19 is equipped with a conveyor belt assembly 23 inside. The conveyor belt assembly 23 and the palletizing box 11 are on the same horizontal line. A control box 24 is fixedly connected to the outer surface of the conveyor body 19. During the conveying operation, the carton material is placed on the conveyor belt assembly 23, and the conveyor belt assembly 23 conveys the carton material to the end close to the palletizing box 11. The start and stop of the conveyor belt assembly 23 can be controlled by pressing the control box 24. During the conveying process, the drive motor 21 is started. The output shaft of the drive motor 21 drives the brush roller 22 to rotate and wipe and clean the surface of the carton material. During the conveying operation, the carton material is placed on the conveyor belt assembly 23, and the control box 24 is pressed to start the conveyor belt assembly 23. The conveyor belt assembly 23 conveys the carton material to the end close to the palletizing box 11. After being conveyed, the carton material falls into the palletizing box 11 along the inclined feed port of the palletizing box 11 to realize fully automatic stacking and conveying operation.

[0030] To address the problems existing in the prior art, this utility model provides a fully automatic cardboard box stacking conveyor. When the cardboard box material falls along the inside of the stacking box 11, it will contact the inclined surface of the limiting post 13 and squeeze it to rotate. When the limiting post 13 rotates, it squeezes the torsion spring 14 to make it contract. After the cardboard box material falls, the limiting post 13 is pushed back to its original position under the force of the torsion spring 14. If the compression plate 17 does not rise to its original position after the cardboard box material is compressed, the threaded rod 25 can be turned to drive the U-shaped frame 12 to slide downward to limit the compressed cardboard box material, so as to avoid the cardboard box material rebounding and resetting after compression, further reducing its volume and improving the convenience of transportation operation.

[0031] Palletizing box 11: As the main body of the equipment, it provides installation space for other components and is the main place for stacking and compressing cartons;

[0032] U-shaped frame 12: used for mounting and supporting the limiting column 13, and can slide within the palletizing box 11 to adjust its position;

[0033] Limiting post 13: It plays a preliminary role in blocking and positioning the falling cardboard box material, and can limit the cardboard box after compression;

[0034] Torsion spring 14: provides a restoring force for the limit post 13;

[0035] Round rod 15: unidirectionally restricts the rotation of the limiting post 13;

[0036] Cylinder 16: Provides power for the movement of the compression plate 17;

[0037] Compression plate 17: Driven by cylinder 16, it compresses the carton material;

[0038] Rectangular groove 18: limits the sliding trajectory of U-shaped frame 12 to ensure its sliding stability;

[0039] Conveyor body 19: It carries components such as the conveyor belt assembly 23 and is the main structure of the conveying section;

[0040] Drive motor 21: provides power for the rotation of brush roller 22;

[0041] Brush roller 22: Rotates under the drive of drive motor 21 to clean the surface of the carton material;

[0042] Conveyor belt assembly 23: Responsible for conveying cardboard box materials;

[0043] Control box 24: Controls the start and stop of the conveyor belt assembly 23;

[0044] Threaded rod 25: It drives the U-shaped frame 12 to slide by rotating, so as to adjust its height to adapt to different stacking requirements. After compression, it can assist in limiting the position and facilitate handling.

[0045] Working principle:

[0046] The first step involves placing the cardboard box material onto the conveyor belt assembly 23 during the conveying operation. Pressing the control box 24 starts the conveyor belt assembly 23, which then transports the cardboard box material towards one end of the palletizing box 11. After being conveyed, the cardboard box material falls into the palletizing box 11 through its inclined inlet, achieving fully automatic stacking and conveying. During the conveying process, the drive motor 21 is started, and its output shaft drives the brush roller 22 to rotate, wiping and cleaning the surface of the cardboard box material. After the material is loaded and stacked, the cylinder 16 is activated, and its output shaft pushes the compression plate 17 downwards, allowing it to slide inside the palletizing box 11 and press... The compression plate 17 slides and squeezes the cardboard material to compress it, saving space. The compression plate 17 is located between the two limiting posts 13 and does not contact them. The inside of the palletizing box 11 is provided with a rectangular slide groove 18. The U-shaped frame 12 is slidably connected inside the rectangular slide groove 18 to ensure the sliding trajectory of the U-shaped frame 12. By holding and turning the threaded rod 25, since the threaded rod 25 is threadedly connected inside the palletizing box 11, turning the threaded rod 25 can drive the U-shaped frame 12 to slide, thereby adjusting its placement height to meet the palletizing needs of different heights. After the cardboard material is compressed and bundled, turning the threaded rod 25 pulls the U-shaped frame 12 up, and the cardboard material can be picked up and transported.

[0047] In the second step, when the cardboard material falls into the inside of the palletizing box 11, it will contact the inclined surface of the limiting post 13 and squeeze it to rotate. When the limiting post 13 rotates, it squeezes the torsion spring 14 to make it contract. After the cardboard material falls, it loses the squeezing force on the limiting post 13. Under the action of the torsion spring 14, it pushes the limiting post 13 to reset. The round rod 15 connected to the surface of the U-shaped frame 12 can limit the limiting post 13. After the cardboard material is compressed, if the compression plate 17 does not rise to reset, turning the threaded rod 25 can drive the U-shaped frame 12 to slide downward to limit the compressed cardboard material.

[0048] 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. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
