[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0028] The present application provides an automatic packing system for packaging boxes, which is mainly used to solve the shortcomings of an automatic packing device for packaging boxes disclosed in Chinese Patent Publication No. CN218559291U, including: 1. The second conveyor belt of the device is arranged horizontally, which causes the cardboard to easily flip when falling from the second conveyor belt, affecting the subsequent stacking and bundling quality; 2. The cardboard is subjected to a large impact force during the falling process, which easily causes the cardboard to deviate, increases the difficulty of alignment, and reduces the accuracy and efficiency of packaging. The following technical solutions are provided, which will be combined with Figure 1-Figure 4 Make a detailed description:

[0029] An automatic packaging system for packaging boxes mainly comprises a bottom plate 1, a conveying mechanism 2 arranged on the top of the bottom plate 1 and a carrying plate 3, one end of the carrying plate 3 is located below the rear end of the conveying mechanism 2, wherein:

[0030] The conveying mechanism 2 comprises a mounting frame 21 arranged on the bottom plate 1, three transmission rollers 22 rotatably mounted on the mounting frame 21, a transmission belt 23 sleeved on the three transmission rollers 22, and a motor 24 mounted on the mounting frame 21 and having an output end fixed to the rotating shaft of one of the transmission rollers 22, wherein two adjacent transmission rollers 22 are arranged on the same horizontal plane, another transmission roller 22 is closer to the carrying plate 3 and lower than the other two transmission rollers 22, and one of the specially designed transmission rollers 22 is lower than the other two. This unique design effectively reduces the flipping phenomenon when the packaging box cardboard is transferred from the conveying mechanism 2 to the carrying plate 3, which is the first beneficial effect of the system;

[0031] A plurality of synchronously operated oil cylinders 31 are connected between the bottom of the carrying plate 3 and the top of the bottom plate 1 to realize lifting and lowering adjustment to adapt to the stacking of cardboards at different heights. This lifting and lowering function not only improves the adaptability of the system, but also enables the carrying plate 3 to stably receive cardboards at different heights, which is the second beneficial effect of the system;

[0032] A conveying mechanism 2 32 is provided on the carrying plate 3, the head end of the conveying mechanism 2 32 corresponds to the tail end of the conveying mechanism 1 2, a strapping machine 33 located between the conveying mechanism 2 32 and the conveying mechanism 1 2 is provided on the carrying plate 3, a buffer assembly 34 corresponding to the strapping machine 33 is provided on the top of the carrying plate 3, a left-right alignment assembly 35 is provided on the top of the carrying plate 3, and a control assembly 36 for pushing the bundled packaging box cardboard to the conveying mechanism 2 32 is also provided on the top of the carrying plate 3. The conveying mechanism 2 32, the strapping machine 33, the buffer assembly 34, the left-right alignment assembly 35 and the control assembly 36 integrated on the carrying plate 3 work together to realize the accurate conveying, alignment, strapping and pushing out of the cardboard, and the left-right alignment assembly 35 ensures that the left and right edges of the cardboard are aligned, thereby improving the packaging accuracy, which is the third beneficial effect of the system;

[0033] After the strapping machine 33 completes the strapping, the control component 36 pushes the bundled cardboard to the second conveying mechanism 32, realizing automatic pushing out and improving the packaging efficiency, which is the fourth beneficial effect of the system;

[0034] At the same time, the buffer assembly 34 absorbs the impact force, reduces the deviation of the cardboard when it falls, and ensures the smooth transmission of the cardboard, which is the fifth beneficial effect of the system;

[0035] The whole system has a high degree of automation and is easy to operate, which reduces manual intervention and labor intensity. At the same time, the modular design facilitates maintenance and upgrading. These are additional beneficial effects of the system. Through these implementation methods, this system not only improves production efficiency, but also ensures packaging quality, meeting the modern packaging industry's higher requirements for automation and intelligence.

[0036] For details, please refer to Figure 2 , Figure 3 and Figure 4 The top of the carrier plate 3 is constructed with a mounting groove 37, which runs through one end of the carrier plate 3 away from the conveying mechanism 1 2, providing space for the integration of the conveying mechanism 2 32. The conveying mechanism 2 32 includes two horizontally rotatable transmission rollers 2 321 mounted on the inner wall of the mounting groove 37, and an integral transmission belt 2 322 is sleeved on the two transmission rollers 2 321. A motor 2 323 whose output end is fixed to the rotating shaft of one of the transmission rollers 2 321 is installed on the carrier plate 3. Such a layout allows the cardboard to be smoothly and continuously transported through the transmission belt 2 322 after bundling. This implementation method improves the transportation efficiency of the cardboard.

[0037] In this scenario, see Figure 2 , Figure 3 and Figure 4, the top of the carrying plate 3 is constructed with a device slot 38 corresponding to the strapping machine 33. This design allows the buffer assembly 34 to accurately correspond to the strapping machine 33, ensuring that the cardboard can be placed and transported smoothly after being strapped. The buffer assembly 34 includes a buffer support plate 341 movably arranged inside the device slot 38. The top side of the buffer support plate 341 is always higher than the top side of the second conveyor belt 322. This height difference ensures that the bundled cardboard will not interfere with the second conveyor belt 322 when placed, thereby avoiding possible jamming or damage, and the bundled packaging box cardboard can be smoothly pushed onto the second conveyor belt 322. A number of evenly distributed shock absorbers 342 are connected between the bottom of the buffer support plate 341 and the device slot 38. In order to achieve a better buffering effect, a number of evenly distributed shock absorbers 342 are connected between the bottom of the buffer support plate 341 and the device slot 38. The function of these shock absorbers 342 is to absorb the impact force when the cardboard falls, reducing the impact on the cardboard and the equipment;

[0038] Furthermore, a spring 343 is sleeved on the shock absorber 342 to provide additional buffering force to ensure that the impact on the cardboard during the falling process is effectively alleviated;

[0039] In this solution, the combination of the shock absorber 342 and the spring 343 provides a double-layer buffer mechanism, which significantly improves the ability to absorb impact force and protects the cardboard and equipment.

[0040] The design and implementation of the left and right alignment components 35 are the key innovations to ensure accurate alignment of the paperboards. Figure 2 , Figure 3 and Figure 4 There are two left and right alignment components 35 and they are located on the same horizontal line. This layout ensures the symmetry and consistency of the alignment operation. The two left and right alignment components 35 are respectively located on the opposite sides of the carrier plate 3. The left and right alignment components 35 include a connecting block 351 horizontally installed on the carrier plate 3. A horizontal electric push rod 352 is installed on the connecting block 351. A vertical alignment plate 353 is fixed on the output end of the electric push rod 352. The output ends of the two electric push rods 352 are opposite to each other. The alignment plate 353 is a component that directly contacts the cardboard and pushes it to align. The two alignment plates 353 ensure that the cardboard is aligned synchronously from both sides, thereby improving the accuracy and efficiency of the alignment.

[0041] For further information, see Figure 2 and Figure 4The design and implementation of the control component 36 are crucial to realizing the automatic pushing out of the cardboard. The control component 36 is mainly composed of an electric push rod 361, which is installed on the top of the carrier plate 3, arranged along the length direction of the conveyor belt 322, and located on the side of the strapping machine 33 facing away from the conveyor belt 322. A vertically arranged push plate 362 is fixed on the output end of the electric push rod 361. This design enables the push plate 362 to directly contact the bundled cardboard. The vertical setting of the push plate 362 ensures that during the pushing process, the cardboard can be smoothly pushed in a direction perpendicular to the conveyor belt, so that it can be smoothly transferred from the strapping machine 33 to the conveyor belt 322.

[0042] For further information, see Figure 2 , Figure 3 and Figure 4 The top of the carrier plate 3 is constructed with a storage groove 39 located between the buffer support plate 341 and the second conveyor belt 322. The storage groove 39 has a baffle 391 hinged inside. This layout allows the baffle 391 to operate without affecting the normal transmission of the cardboard. The carrier plate 3 is equipped with a motor 392 whose output end is fixed to one end of the rotating shaft of the baffle 391. The rotating shaft of the baffle 391 is close to the buffer support plate 341. The baffle 391 can be rotated to a vertical state or a horizontal state. When the baffle 391 is in a vertical state, the front and rear ends of the cardboard can be aligned by the push of the push plate 362. When the baffle 391 is rotated to a horizontal state, an unobstructed path is provided for the transmission of the cardboard, ensuring that the cardboard can smoothly slide from the buffer support plate 341 to the second conveyor belt 322.

[0043] The specific operating steps of the device are:

[0044] The cardboard is first placed at the starting position of the conveyor mechanism 2 on the bottom plate 1, ready to enter the packaging process;

[0045] Start the motor 24 to drive the conveyor belt 23 on the conveying mechanism 2 to convey the cardboard to the carrying plate 3. The inclined setting of one end of the conveyor belt 23 can prevent the cardboard from turning over. The shock absorber 342 and the spring 343 in the buffer assembly 34 absorb the possible impact force to ensure that the cardboard is stably placed on the carrying plate 3.

[0046] During the process of conveying the cardboard to the carrying plate 3, the height of the carrying plate 3 is adjusted by the oil cylinder 31 according to the height of the cardboard to adapt to the stacking of cardboards of different heights;

[0047] After the cardboard reaches the carrier plate 3, the electric push rod 352 in the left and right alignment assembly 35 is activated to push the vertical alignment plate 353 to align the edge of the cardboard to a predetermined position;

[0048] The baffle plate 391 is controlled by the motor 392 to rotate to a vertical state, and the push plate 362 pushes the paperboard to ensure that the head and tail are aligned;

[0049] The strapping machine 33 automatically straps the aligned cardboards to complete the initial fixation of the package;

[0050] After the cardboards are bundled, the motor 392 drives the baffle 391 to rotate to a horizontal state, ready to be pushed out;

[0051] The second electric push rod 361 is started, pushing the push plate 362 to push the bundled cardboard from the buffer support plate 341 to the second conveyor belt 322 .

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
