TECHNICAL FIELD
[0001] The application relates to the technical field of carton sheet processing, in particular to a carton sheet stacking device. BACKGROUND
[0002] In the current carton sheet production process, the finished carton sheets are sequentially discharged through the conveying port of the production line and are regularly stacked at the outlet by a stacking device. The existing stacking device is mainly composed of a stacking frame which is installed at a specific position of the conveying outlet of the production line. The stacking frame is designed with a vertical limiting baffle, and the carton sheets contact the limiting baffle during the conveying process and gradually fall along the limiting baffle onto the conveying belt below to form a stack.
[0003] However, the stacking device has certain limitations in actual application. Specifically, the stacking height is limited, which significantly affects the stacking effect due to the relative height between the outlet height of the production line and the position of the stacking place. When the outlet height is too high, the output carton sheets fall at a drop angle close to 90° at the stacking place, which cannot achieve effective stacking. Conversely, if the outlet height is set too low, although it is beneficial to the stacking of the carton sheets, it will limit the number of stacks and affect the production efficiency. CONTENT OF THE UTILITY MODEL

[0007] By adopting the above technical scheme, the support plate is rotated to a state perpendicular to the stacking plate, and the stacking plate and the support plate form a temporary support area, which can guide the carton sheets to orderly fall into the support area for stacking. After the stacking in the area is almost completed, the support plate is controlled to rotate downward to a discharging state parallel to the stacking plate, so that the carton sheets fall onto the conveying belt below for stacking. This is equivalent to dividing one stacking area into two sections, the first section is temporarily supported, and then falls into the second section area, avoiding the problem of vertical falling caused by the outlet height being too high, and improving the stacking stability.
[0008] Optionally, the stacking frame further comprises a telescopic supporting rod; the telescopic supporting rod is controlled by a second driving member, passes through one of the stacking plates above the supporting plate, and goes in and out of the stacking channel to form temporary support for the carton pieces; another of the stacking plates is provided with a transition rod for supporting one end of the carton pieces when the telescopic supporting rod is retracted; the transition rod is controlled by a third driving member; the transition rod and the telescopic supporting rod pass through different stacking plates.
[0009] By adopting the above technical scheme, the telescopic supporting rod temporarily supports the carton pieces, and the transition rod forms phased stacking in the stacking channel, thereby reducing misalignment or collision caused by direct falling of the carton pieces.
[0010] Optionally, the stacking frame further comprises a movable assembly for driving one of the stacking plates to move forward and backward relative to another of the stacking plates to regulate the carton pieces in the stacking channel.
[0011] By adopting the above technical scheme, the movable assembly is arranged to enable the stacking plates to move forward and backward, thereby regulating the carton pieces in the stacking channel and ensuring the neatness and stability of the stacking.
[0012] Optionally, the bottom of the stacking plate moving forward and backward is provided with a plurality of limiting blocks, and the supporting plate is provided with a plurality of accommodation holes for the limiting blocks to move.
[0013] By adopting the above technical scheme, the limiting blocks and the accommodation holes cover the gap between the stacking plate and the supporting plate.
[0014] Optionally, the telescopic supporting rod extends obliquely upward.
[0015] By adopting the above technical scheme, the telescopic supporting rod extends obliquely upward, which helps the carton pieces gradually transition during stacking and improves the stability of the stacking.
[0016] Optionally, the movable assembly comprises a driving roller rotatably connected to the stacking frame, a plurality of eccentric wheels are distributed on the driving roller; a hook portion is connected to the upper end of the stacking plate and cooperates with the eccentric wheels, the hook portion comprises two parallel limiting plates and an arc plate connecting the two limiting plates, the eccentric wheels move between the two limiting plates to drive the hook portion to move when the eccentric wheels rotate; a guide member is arranged between the stacking plate and the stacking frame to enable the stacking plate to move in a straight line forward and backward relative to another of the stacking plates.
[0017] By adopting the above technical scheme, the stacking plate moves in a straight line forward and backward, and the movement is stable and reliable.
[0018] Optionally, the guide member comprises a guide rod perpendicularly connected to the stacking plate, and a guide sleeve fixed to the stacking frame and adapted to the guide rod, the guide rod is arranged in the guide sleeve.
[0019] By adopting the above technical solution, the guide rod and guide sleeve provide stable guidance for the forward and backward movement of the stacked plates, ensuring the accuracy and smoothness of the movement.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] This application discloses a cardboard box stacking device, which aims to improve the cardboard box stacking problem.
[0030] Reference Figure 1 , 2 The stacking device includes a stacking frame 1, inside which two vertically parallel stacking plates 2 are installed. The two stacking plates 2 form a stacking channel for paper carton sheets to pass through. A support plate 3 is hinged to the bottom of the stacking plate 2 on the stacking frame 1. The rotation angle of the support plate 3 is controlled by a first driving component 4.
[0031] When the falling height is high and the angle is large, the support plate 3 is lifted to a vertical state to form a temporary stacking space for the carton blanks, the temporary stacking space is close to the position of the carton blank output port, so that the carton blanks slide onto the support plate 3 in the stacking channel at a small falling angle, and after a certain number of carton blanks are stacked on the support plate 3, the support plate 3 is controlled to rotate downward, and the cartons can fall into the stacking area below.
[0032] In the embodiment, the first driving member 4 can be a gas cylinder, the piston rod of the gas cylinder is hinged to the support plate 3, and the cylinder body of the gas cylinder is hinged to the stacking frame 1, the rotation of the support plate 3 is controlled by the extension and retraction of the piston rod of the gas cylinder, and the switching between the lifting and downward states of the support plate 3 is realized.
[0033] Referring to Figure 1 , 2 , the stacking frame 1 further comprises a telescopic support rod 7 controlled by the second driving member 5, the telescopic support rod 7 passes through one of the stacking plates 2 above the support plate 3 and enters and exits the stacking channel to form temporary support for the carton blanks. The other stacking plate 2 is provided with a transition rod 8, which supports one end of the carton blanks when the telescopic support rod 7 is retracted. The transition rod 8 is controlled by the third driving member 6, and the transition rod 8 and the telescopic support rod 7 pass through different stacking plates 2. The transition rod 8 and the telescopic support rod 7 work together to evenly distribute the force on both ends of the carton blanks and prevent unilateral collapse.
[0034] When the telescopic support rod 7 is completely retracted outside the stacking channel, the transition rod 8 will also be retracted outside the stacking channel under the action of the third driving member 6, so that the carton blanks stacked on the telescopic support rod 7 and the transition rod 8 naturally fall onto the temporary stacking area formed by the two support plates 3, realizing the phased stacking in the stacking channel.
[0035] Referring to Figure 1 , 2 , further, the telescopic support rod 7 extends upwardly and obliquely, that is, the horizontal height of the end of the telescopic support rod 7 close to the second driving member 5 is lower than the end of the telescopic support rod 7 away from the second driving member 5.
[0036] The second driving member 5 and the third driving member 6 can both be gas cylinders, which are fixed on the stacking plates 2 and connected to the corresponding transition rods 8 or telescopic support rods 7, and the movement of the transition rods 8 or the telescopic support rods 7 is controlled by the extension and retraction of the gas cylinders. In the embodiment, the number of transition rods 8 and telescopic support rods 7 can be set according to actual conditions.
[0037] Referring to Figure 2 , 3 , the stacking frame 1 further comprises a movable assembly for driving one stacking plate 2 to move forward and backward towards another stacking plate 2 to regulate the carton blanks in the stacking channel.
[0038] Specifically, the moving assembly comprises a driving roller 9 rotatably connected to the stacking frame 1, and a plurality of eccentric wheels 10 are distributed on the driving roller 9. A guide member is arranged between the stacking plate 2 and the stacking frame 1, and is used to move the stacking plate 2 in the front-rear linear direction towards another stacking plate 2. The upper end of the stacking plate 2 is fixedly connected with a bent hook part 11 matched with the eccentric wheel 10, and the bent hook part 11 comprises two parallel limiting plates 12 and an arc plate 13 connecting the two limiting plates 12. The eccentric wheel 10 moves between the two limiting plates 12, so that the eccentric wheel 10 and the bent hook part 11 form a mechanical linkage, and the rotational movement of the eccentric wheel 10 is converted into the periodic linear movement of the stacking plate 2. That is, the eccentric wheel 10 of the driving roller 9 rotates one revolution, drives the bent hook part 11 to move one stroke, and makes the stacking plate 2 complete one “forward-reset” action to push the carton pieces to be stacked in order.
[0039] Referring to Figure 2 , 3 , the guide member comprises a guide rod 14 and a guide sleeve 15, the guide rod 14 is fixedly connected with the stacking plate 2 perpendicularly, and the guide sleeve 15 is fixed on the stacking frame 1. The guide rod 14 is arranged in the guide sleeve 15, so as to ensure the linearity and stability of the stacking plate 2 during the movement. In the embodiment, two guide rods 14 are symmetrically arranged to improve the stability of the stacking plate 2 during the forward and backward movement.
[0040] Referring to Figure 3 , 4 , the bottom of the forward and backward moving stacking plate 2 is fixed with a plurality of limiting blocks 16, and the limiting blocks 16 are distributed at equal intervals. The supporting plate 3 is provided with a plurality of accommodation holes 17 for the movement of the limiting blocks 16. The limiting blocks 16 and the accommodation holes 17 cover the gap between the stacking plate 2 and the supporting plate 3, so that the carton pieces cannot pass through the gap between the two.
[0041] The implementation principle of the carton piece stacking device in the embodiment of the application is as follows:
[0042] During stacking, the telescopic supporting plate 3 is extended to form a first layer of stacking, and after a certain amount of stacking, the telescopic supporting plate 3 is retracted to the second layer where the supporting plate 3 is located for stacking. After the second layer of stacking reaches a certain height, the supporting plate 3 is opened, and the stacked carton pieces fall into the adsorbed stacking area. Through the layered stacking mode, the problem of stacking height is solved.
[0043] The above are the preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
