[0025] Reference Figure 1 , a packaging box turning mechanism includes a loading conveyor 100, a packing conveyor 200, a unloading conveyor 300 and a first box turning module, wherein the loading conveyor 100 has a plurality of loading rollers 110 arranged at intervals along the left and right directions, and the loading conveyor 100 can be a roller conveyor, which has a motor inside. The motor drives the plurality of loading rollers 110 to rotate through a chain or a synchronous belt transmission, thereby realizing the transportation and loading of the packaging box; the packing conveyor 200 is located at the conveying end of the loading conveyor 100, and the conveying direction of the packing conveyor 200 is toward the side away from the loading conveyor 100, with the side horizontally perpendicular to the conveying direction of the packing conveyor 200 as Feeding side; the unloading conveyor 300 is located at the conveying end of the cartoning conveyor 200, and the conveying direction of the unloading conveyor 300 is toward the side away from the cartoning conveyor 200; the first box turning module is located at the position of the loading conveyor 100 close to the cartoning conveyor 200, and the first box turning module is located between the two loading rollers 110 and is provided with a first turning frame 410, the first turning frame 410 can move in the front and rear directions and rotate along the axis in the left and right directions, the first turning frame 410 is located near the feeding side and is formed with a first limit rod 411 extending upward, and the first turning frame 410 is located between the two loading rollers 110 and is formed with a first turning rod 412.

[0026] As can be seen from the above, the loading conveyor 100, the packing conveyor 200, and the unloading conveyor 300 are arranged in sequence. The packaging boxes can be loaded on the loading conveyor 100, transferred for packing on the packing conveyor 200, and unloaded on the unloading conveyor 300 in sequence. The loading conveyor 100 is provided with a plurality of loading rollers 110 arranged at intervals along the left and right directions. The plurality of loading rollers 110 rotate to drive the packaging boxes to be transported to the packing conveyor 200, and the interval space between two adjacent loading rollers 110 can provide a space for the first turning frame 410 in the first turning module to move. When the packaging box moves to the position where the loading conveyor 100 is close to the packing conveyor 200, the packaging box is located above the first turning rod 412, and the first limiting rod 411 is located on the side of the packaging box close to the feeding side. When the packaging box needs to be turned over, the first turning frame 410 moves in the direction away from the feeding side and rotates along the axis in the left and right directions. At this time The first overturning rod 412 is rotated upward and protrudes from the feeding roller 110, lifting the packaging box away from the feeding side, so that the packaging box slides along the first overturning rod 412 to one side of the first limiting rod 411, and the packaging box is limited by the first limiting rod 411, gradually realizing the overturning and falling of the packaging box. After completion, the overturned packaging box is transported to the packing conveyor 200. At this time, the products can be loaded into the packaging box at the feeding side to realize product packaging. Then the packing conveyor 200 sends the packaging box to the unloading conveyor 300, and the unloading conveyor 300 moves the packaging box to the next workstation. In this way, the first overturning frame 410 is used to overturn from the bottom side of the packaging box and keep the packaging box limited, effectively preventing damage during the overturning process of the packaging box, realizing stable and efficient overturning and falling of the packaging box, and the rotation axis of the first overturning frame 410 moves as the packaging box is overturned, which can better save the space required for overturning and falling the packaging box, and is more practical.

[0027] The first box turning module mainly has a driving source that can drive the first turning frame 410 to move in the front-back direction and rotate along the axis in the left-right direction. For example, the first box turning module is equipped with a linear driving source such as a cylinder, an electric screw or a hydraulic cylinder, and a driving motor is installed on the linear driving source. At this time, the driving motor directly drives the first turning frame 410, and the linear driving source provides the first turning frame 410 with a driving force for moving in the front-back direction, and the driving motor provides the first turning frame 410 with a driving force for rotating along the axis in the left-right direction. In order to reduce the number of driving sources, such as Figure 2As shown, in this embodiment, the first box turning module includes a first box turning drive 420, a first slide 430 and a first connecting rod 440. The first box turning drive 420 is connected to the position of the loading conveyor 100 below the loading roller 110. The first box turning drive 420 drives the first slide 430. The first box turning drive 420 can drive the first slide 430 to move in the front and rear directions. The bottom of the first limit rod 411 is rotatably connected to the first slide 430. The two ends of the first connecting rod 440 are respectively rotatably connected to the bottom side of the first turning rod 412 and the side of the loading conveyor 100 away from the feeding side. The rotation axis of the first limit rod 411 and the rotation axes of the two ends of the first connecting rod 440 extend in the left and right directions. After the turned and laid box is transferred out of the loading conveyor 100, the first box turning driving member 420 drives the first turning frame 410 to move in the direction close to the feeding side, so that the first turning frame 410 is reversed and reset.

[0028] When the packaging box is small, or the width of the first tilting rod 412 and the first limiting rod 411 in the left-right direction is large, sufficient support force can be provided for the packaging box. In this case, only one first tilting frame 410 can be provided. However, to improve the stability of the packaging box's tilting, in this embodiment, multiple first tilting frames 410 are provided at intervals along the left-right direction. When the first slide 430 moves in the front-to-back direction, it can drive multiple first tilting frames 410 to rotate simultaneously. In this case, multiple first tilting frames 410 are used to simultaneously assist in the tilting of the packaging box, greatly improving the stability of the packaging box's tilting and laying.

[0029] To further enhance the stability of the first slide 430, in this embodiment, a first slide shaft 450 extending in the front-to-rear direction is connected to the loading conveyor 100 below the loading roller 110. The first slide 430 is slidably connected to the first slide shaft 450. The first slide 430 slides back and forth along the first slide shaft 450, and the sliding engagement between the first slide 430 and the first slide shaft 450 enhances the stability of the first slide 430. In particular, when multiple first tilting frames 410 are mounted on the first slide 430, the first slide shaft 450 balances the load of the first slide 430, preventing the first tilting frames 410 from shifting and interfering with the loading roller 110.

[0030] The packing conveyor 200 may be a roller conveyor or a chain conveyor, etc. In order to improve the accuracy of the packing conveyor 200 in conveying the packing boxes, a structure for blocking and limiting the packing boxes may be installed in the packing conveyor 200.

When the packaging box moves to the two conveyor belts, the two conveyor belts rotate synchronously to realize the transfer of the packaging box on the packing conveyor 200. When the packaging box is moved into place, the two conveyor belts stop working, and the baffle 560 on the top side of the transmission block 530 is used to block and limit the packaging box, so that the packaging box can be moved into place accurately, and then the products to be packed are packed into the packaging box. After completion, the telescopic drive member 540 drives the transmission block 530 to rotate, causing the baffle 560 to rotate and descend, and the two conveyor belts continue to work to send the completed packed packaging box to the unloading conveyor 300, so that the packaging box can be transported into, positioned, and sent out on the packing conveyor 200.

[0031] In order to conveniently adapt to limiting packaging boxes of different sizes, in the embodiment, the fixing frame 510 is provided with an adjusting screw rod 550, the adjusting screw rod 550 is drivingly connected with the connecting seat 520, and the adjusting screw rod 550 can drive the connecting seat 520 to move along the left-right direction; the adjusting screw rod 550 can be a hand-operated screw rod or an electric screw rod. According to different specifications of the packaging boxes, the packaging boxes need to be positioned at different positions on the boxing conveyor 200; at this time, the position of the connecting seat 520 can be adjusted through the adjusting screw rod 550 according to different use requirements, so that the left-right position of the baffle 560 is changed, and the position of the packaging box for positioning is flexibly and conveniently adjusted.

In the blanking conveyor 300, a plurality of blanking roller 310 is arranged along the left-right direction interval, is rotated by a plurality of blanking roller 310 to realize that the packaging box that completes packaging is sent out, and the interval space between the adjacent two blanking roller 310 can provide the space of second turning frame 600 in second turning box module for activity, when the packaging box moves to the position of blanking conveyor 300 close to boxing conveyor 200, the packaging box is located above the second turning rod, and the second limiting rod is located at the side away from the material inlet side of the packaging box, when needing to turn over the packaging box, the second turning frame 600 moves towards the direction close to the material inlet side and rotates along the axis of left and right direction, at this time, the second turning rod rotates upwards and protrudes from the blanking roller 310, lifts the position close to the material inlet side of the packaging box, so that the packaging box slides to the side of the second limiting rod along the second turning rod, is limited by the second limiting rod, gradually realizes the turning over of the packaging box, after completion, the opening of the packaging box faces upwards, and the blanking roller 310 continues to move and transports the turned packaging box to the next station.

[0033] In actual application, the second box turning module can adopt the same structure as the first box turning module. Specifically, the second box turning module includes a second box turning drive, a second slide and a second connecting rod. The second box turning drive is connected to the position of the unloading conveyor 300 below the unloading roller 310. The second box turning drive drives the second slide. The second box turning drive can drive the second slide to move in the front and back directions. The bottom of the second limit rod is rotatably connected to the second slide. The two ends of the second connecting rod are respectively rotatably connected to the bottom side of the second turning rod and the side of the unloading conveyor 300 close to the feeding side. The rotation axis of the second limit rod and the rotation axes at both ends of the second connecting rod extend in the left and right directions. The second box-turning driving member can provide a driving force for the second turning frame 600 to move in the front-to-back direction. When the packaging box enters the unloading conveyor 300, the second slide is located at a position away from the feeding side. When the packaging box needs to be turned back to the right side, the second box-turning driving member drives the second slide to move in the direction close to the feeding side. Since the second turning rod is connected to the position of the unloading conveyor 300 away from the feeding side by a second connecting rod, the second turning rod moves in the direction away from the feeding side while rotating upward, and drives the second limit rod to rotate downward as well. In this way, the second turning frame 600 can turn the packaging box back to the right side and realize the synchronous movement of the rotation axis of the second turning frame 600, reducing the space required in the front-to-back direction.

[0034] In some embodiments, a box-pushing driving member 710 is connected to a position of the packing conveyor 200 away from the infeed side. The box-pushing driving member 710 is drivably connected to a box-pushing member 720. The box-pushing driving member 710 can drive the box-pushing member 720 toward or away from the infeed side. The box-pushing driving member 710 can provide a driving force for the box-pushing member 720 to move in the front-to-back direction. When the packaging box is moved into position on the packing conveyor 200, the box-pushing driving member 710 drives the box-pushing member 720 to move toward the infeed side, pushing the packaging box toward the infeed side by a set distance. In this way, the packaging box can be further positioned in the front-to-back direction, making it easier to load products into the packaging box.

[0035] In actual applications, the first box turning drive 420, the second box turning drive, the box pushing drive 710, and the telescopic drive 540 are all used to provide driving force for reciprocating movement in a linear direction, and their structural forms include various types, such as cylinders, screw rods, or hydraulic cylinders.

[0036] In some embodiments, the top side of the loading conveyor 100 is provided with feed guides 800 spaced apart in the front-to-back direction. When a package box enters the loading conveyor 100, the feed guides 800 guide the package box's entry, preventing horizontal deviation of the package box while moving on the loading conveyor 100 and improving the accuracy of the package box's delivery to the packing position. In actual applications, to better guide the package box between the two feed guides 800, the ends of the two feed guides 800 facing away from the packing conveyor 200 are inclined, so that the distance between the two feed guides 800 gradually decreases as they approach the packing conveyor 200, thereby facilitating the guided transportation of the package box.

[0037] In some embodiments, discharge guides 900 are spaced apart along the front-to-back direction on the top side of the discharge conveyor 300. When the finished product boxes are transported from the discharge conveyor 300, the discharge guides 900 can be used to guide the boxes, preventing horizontal deviations while moving on the discharge conveyor 300 and improving the accuracy of the boxes' transport to the next workstation. Similarly, to better guide the boxes between the two discharge decks, the ends of the two discharge guides 900 near the boxing conveyor 200 are inclined, so that the distance between the two infeed guides 800 gradually decreases as they move away from the boxing conveyor 200, making it easier to guide the boxes between the two discharge guides 900 and transport them out.

[0038] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
