[0002] After printing and roll cutting, multiple cardboard boxes are bundled together by a packing machine, and these stacks are then piled up for easy transport. In existing technology, cardboard stacking equipment cannot effectively connect the packing machine and the transport trolley simultaneously. For example, CN114476798A discloses a cardboard sheet stacking machine for cardboard processing, in which an inclined belt conveys the cardboard boxes into the stacking box. Due to the speed and angle difference between the packing machine's conveyor belt and the inclined belt, the cardboard boxes delivered by the packing machine are prone to jamming when they come into contact with the inclined belt, causing the cardboard to tilt. Furthermore, the fixed height of the inclined belt's tail end results in a fixed packing height, which is unsuitable for stacking cardboard boxes of various sizes. Therefore, it is necessary to provide a device that reliably connects to the packing machine and can accommodate stacking at various heights. Utility Model Content

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is combined with Figures 1 to 7 This invention describes a stacking device for connecting cardboard packaging machines according to an embodiment of the present invention.

[0029] The stacking device of the connecting carton packing machine of this embodiment includes a main frame 1, a connecting conveyor frame 2, a lifting conveyor frame 3, and a stacking frame 4. One end of the connecting conveyor frame 2 is rotatably installed at the front end of the main frame 1. The lower end of the lifting conveyor frame 3 is rotatably installed at the front end of the main frame 1. The upper end of the lifting conveyor frame 3 is liftably installed at the rear end of the main frame 1. The stacking frame 4 is installed at the upper end of the lifting conveyor frame 3.

[0030] The front end of the main frame 1 is provided with a drive shaft 11, and a plurality of connecting conveyor belts 21 are provided between the connecting conveyor frame 2 and the drive shaft 11. A plurality of lifting conveyor belts 31 are provided between the lifting conveyor frame 3 and the drive shaft 11.

[0031] The connecting conveyor frame 2 is provided with multiple support plates 22, and each support plate is provided with multiple rollers 23. The rolling direction of the rollers 23 is perpendicular to the conveying direction of the connecting conveyor belt 21, and the top of the rollers is flush with the top surface of the connecting conveyor belt 21.

[0032] In this technical solution, the connecting conveyor 2 is located at the output end of the packing machine and is used to receive the cardboard output by the packing machine. The support plate 22 with rollers 23 supports the carton, and the connecting conveyor belt 21 smoothly moves the carton to the lifting conveyor 3. The swingability of the connecting conveyor 2 allows it to make way for adjustments or maintenance of the packing machine. Furthermore, the height of the end of the swingable connecting conveyor 2 is adjustable, adapting to various models of packing machines. The lifting conveyor 3 is used to transport the carton to the stacking rack 4. The bottom of the stacking rack 4 prevents the transfer trolley from moving. During the cardboard stacking process, the stacking rack 4 rises with the lifting conveyor 3, continuously positioning the cardboard that falls into the stacking rack 4. The lifting height of the lifting conveyor 3 is related to the stacking height and is not limited by the height of the stacking rack 4, making it suitable for stacking at various heights.

[0033] Preferably, several connecting conveyor belts 21 are located in the middle of the connecting conveyor frame 2, and support plates 22 are respectively provided on both sides of the connecting conveyor belts 21. This ensures that the installation area of ​​the connecting conveyor belts 21 is the same as the conveyor belt area of ​​the packaging machine, allowing for the conveying of cardboard. Specifically, the connecting conveyor frame 2 is provided with support bars, the front end of which is connected to the support plate 22, and a pulley is provided at the front end of the support bar. The connecting conveyor belts 21 are fitted onto the pulley and the drive shaft 11, simplifying the equipment structure and reducing the volume of the connecting conveyor frame 2.

[0034] In another embodiment of this utility model, the connecting conveyor frame 2 is equipped with a guide frame 24. The guide frame 24 is provided with a guide rail and two sliders. The sliders are connected to guide inclined plates 25, and the two guide inclined plates 25 are positioned directly opposite the stacking rack 4. The guide inclined plates 25 are used to guide the cardboard boxes passing through the connecting conveyor frame 2, so that the cardboard boxes can be aligned with the stacking rack 4 and accurately fall into the stacking rack 4 after being lifted by the conveyor frame 3. The stacking process does not require manual intervention. Specifically, the two opposing guide inclined plates 25 form a funnel-shaped conveying channel. The width of the conveying channel can be adjusted by adjusting the position of the sliders on the guide rail. It is understood that the sliders are provided with locking rods to fix the sliders on the guide rail.

[0035] In order to realize the installation of the connecting conveyor 2 and the lifting conveyor 3 on the main frame 1, the main frame 1 further includes a column 12, and the drive shaft 11 is connected to the column 12 through the mounting shaft;

[0036] The end of the connecting conveyor frame 2 and the front end of the lifting conveyor frame 3 are respectively sleeved on the mounting shaft by bearings;

[0037] The main frame 1 is equipped with a hydraulic cylinder 13, the piston rod of which is connected to the connecting conveyor frame 2, and a lifting drive mechanism 32 is provided at the rear end of the main frame 1.

[0038] The piston rod of hydraulic cylinder 13 extends, causing the connecting conveyor frame 2 to swing. Hydraulic cylinders 13 are located on both sides of the connecting conveyor frame 2, providing more stable support. The lifting drive mechanism 32 is an electric motor, fixed to the top of the stacking rack 4. Vertical support plates are distributed on both sides of the rear end of the support body, and guide racks are installed on the vertical support plates. Gears are distributed on both sides of the end of the lifting conveyor frame 3, meshing with the guide racks to make the lifting and lowering of the lifting conveyor frame 3 smoother. The electric motor drives the gears to rotate, thus realizing the raising and lowering of the lifting conveyor frame 3.

[0039] Preferably, the two ends of the stacking rack 4 are slidably engaged with the vertical support plate, and the stacking rack 4 is rotatably connected to the lifting conveyor 3. When the rear end of the lifting conveyor 3 rises, the stacking rack 4 rises simultaneously under the guidance of the vertical support plate.

[0040] In one embodiment of the present invention, the stacking rack 4 is provided with a front baffle 41, a rear baffle 42 and two vertical plates 43. The two vertical plates 43 are mirror-symmetrically arranged between the front baffle 41 and the rear baffle 42. The front baffle is located above the rear end of the lifting conveyor 3. The front baffle 41 and the rear end of the lifting conveyor 3 form an inlet.

[0041] The bottom ends of the rear baffle 42 and the two vertical plates 43 are respectively provided with supporting flaps 44, which are driven to flip by a cylinder.

[0042] After a transfer trolley removes a cardboard box that has reached the set height from the stacking rack 4, the lifting conveyor 3 moves the stacking rack 4 downwards, and the cylinder drives the supporting flap 44 to a horizontal position. Subsequent cardboard boxes fall into the stacking rack 4 and are supported by the supporting flap 44. After unloading, the transfer trolley moves to below the stacking rack 4, and the cylinder drives the supporting flap 44 to a vertical position, allowing the cardboard boxes to fall onto the transfer trolley. Then, as the height of the cardboard stack increases, the lifting conveyor 3 moves the stacking rack 4 upwards until the stacking height reaches the set value. Then, the lifting conveyor 3 rises until the stacking rack 4 is detached from the cardboard stack, and the transfer trolley removes the cardboard from the stacking rack 4.

[0043] Specifically, the stacking rack 4 is symmetrically equipped with two mounting rods 45, which slide in conjunction with the stacking rack 4. The rear baffle 42 is fixed to the end of the mounting rod 45. The stacking rack 4 is equipped with a slide rail 46, and the top of the vertical plate 43 slides in conjunction with the slide rail 46. The sliding contact between the mounting rods 45 and the stacking rack 4 allows for adjustment of the distance between the rear baffle 42 and the lifting conveyor 3. The top of the vertical plate 43 engages with the stacking rack 4 via a slider and the slide rail 46, making the distance between the two vertical plates 43 adjustable. This allows the stacking rack 4 to be used for cartons of different sizes. It is understood that positioning elements are provided between the mounting rods 45 and the stacking rack 4, and between the slide rail 46 and the slider, to fix their relative positions.
