Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, specifically to a finished cardboard stacking device. Background Technology

[0002] In the paperboard processing and production process, there are processes such as paperboard cutting and collection. When the paperboard is cut out of the paper cutter and enters the collection process, the paperboard falls freely from the paperboard conveyor end into the paperboard collection base. Due to the lack of a paperboard correction and pressing device, the paperboard is stacked unevenly, which causes great trouble for subsequent workers. Not only does it increase the workload, but it also reduces the stacking efficiency.

[0003] Patent document CN221624203U discloses a cardboard stacking and pressing device, including a device support, a conveyor belt body fixedly connected to the top of the device support, and a stacking and pressing assembly disposed on the top of the device support. In this cardboard stacking and pressing device, when cardboard is conveyed from the top of the conveyor belt body, it is guided down to the top of the stacking plate via a guide plate. Then, two electric push rods are activated to drive two pushing plates to move relative to each other inside two support plates, compressing the irregularly placed cardboard into a square stack. Finally, a pressure plate connected to a hydraulic rod is activated to press the stacked cardboard.

[0004] However, the application lacks a vibration function when pressing down on the cardboard, resulting in insufficient stacking compactness and easy presence of internal gaps. Since there is air between the cardboards, simple vertical pressing can only remove some of the air, but a lot of air will remain in the tiny unevenness and gaps between the cardboards. When the pressure block is lifted, the elasticity of the cardboard will cause them to bounce back, failing to achieve the optimal compactness, which will seriously affect the stacking quality. In view of this, a finished cardboard stacking device is proposed to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 This embodiment of a finished cardboard stacking device includes a frame 1 and a stacking platform 2 disposed inside the frame 1. A gantry frame 4 is fixed to the top side of the frame 1. Specifically, the inside of the frame 1 is hollow, and a guide rail 13 that slides with the stacking platform 2 is fixed to the inner side of the frame 1. A sealing door 11 is detachably installed on the front of the frame 1. Two oppositely arranged correction mechanisms 3 are provided on the outer wall of the frame 1. The correction mechanism 3 consists of a correction plate and an electric telescopic shaft. At the same time, a positioning frame for fixing the electric telescopic shaft is installed on the side wall of the frame 1. Perforations are opened on the side of the frame 1 for placing and conveying the correction plate.

[0026] The frame 1 has an inclined guide plate 12 bolted to its top side. A push rod 14 is slidably mounted on the side of the frame 1 away from the sealing door 11, with the end of the push rod 14 abutting against one side of the stacking platform 2. It should be noted that the push rod 14 can be connected to a drive device so that the stacking platform 2 can be moved after the cardboard is stacked.

[0027] In this embodiment, a cardboard stacking device is provided on the gantry frame 4. The cardboard stacking device includes an electric telescopic rod 5 and a pressure plate 6. A connecting shaft 7, which is rotatably connected to the output end of the electric telescopic rod 5, is rotatably mounted on the top side of the pressure plate 6. The output end of the electric telescopic rod 5 is rotatably connected to the connecting shaft 7. A limiting component 8 for guiding the pressure plate 6 is provided on the outer wall of the gantry frame 4. The limiting component 8 includes a connecting plate and a guide rod. The connecting plate is fixed to one side of the gantry frame 4, and the guide rod passes through the interior of the connecting plate. Specifically, when the electric telescopic rod 5 on the gantry frame 4 is activated, its output end drives the pressure plate 6 to move downward through the connecting shaft 7. Under the guidance of the limiting component 8, the pressure plate 6 smoothly presses down on the stacked cardboard, compressing the cardboard and preventing it from scattering during the stacking process.

[0028] To improve the stacking effect, a vibration mechanism 9 is provided on the top side of the pressure plate 6. The vibration mechanism 9 includes a horizontal plate 91, a guide seat 92, a reciprocating assembly 93, and a drive assembly. The guide seat 92 is fixed to the top side of the pressure plate 6, and the reciprocating assembly 93 is disposed on the horizontal plate 91. The guide seat 92 has a guide groove 921 inside that is linked and cooperates with the reciprocating assembly 93. The bottom end of the guide rod is fixed to the top side of the guide seat 92. The reciprocating assembly 93 includes a reciprocating shaft 931, a striking block 932 fixed to the bottom end of the reciprocating shaft 931, and a return spring 933 fixed to the outer surface of the reciprocating shaft 931. The reciprocating assembly 93 and the drive assembly are used in linkage. Specifically, the striking block 932 in the reciprocating assembly 93 moves up and down continuously under the action of the drive assembly, continuously striking the pressure plate 6. The energy generated by the vibration can be transmitted to the stacked cardboard, squeezing out the air between the cardboards, making the cardboards fit together more tightly, reducing the gaps between the cardboard layers, thereby improving the stability and overall strength of the stack.

[0029] In this embodiment, the reciprocating shaft 931 penetrates the interior of the horizontal plate 91. A wheel frame is fixed to the lower surface of the horizontal plate 91, and a guide roller 934, which is rotatably connected to the guide groove 921, is mounted on one side of the wheel frame. The guide groove 921 has a wavy shape. It should be noted that the bottom side of the return spring 933 is fixed to the top side of the horizontal plate 91. The reciprocating assembly 93 contains multiple reciprocating shafts 931, striking blocks 932, and return springs 933, and these multiple reciprocating shafts 931 are equidistantly distributed. The multiple equidistantly distributed reciprocating shafts 931, striking blocks 932, and return springs 933 form a multi-point striking function, enabling multiple striking points to act simultaneously. This allows for more uniform vibration and compaction of the cardboard below the pressure plate 6, avoiding uneven cardboard stacking caused by uneven local pressure, and ensuring that the cardboard in the entire stacking area achieves a good bonding effect.

[0030] In addition, when the horizontal plate 91 moves under the drive of the drive assembly, the guide roller 934 rolls in the wave-shaped guide groove 921, so that the reciprocating shaft 931 can move up and down according to a specific trajectory and frequency, making the striking action more regular and efficient, producing a more stable and powerful vibration effect, and improving the vibration compaction efficiency of the cardboard.

[0031] The driving assembly in this embodiment includes two driving gears 94 and connecting arms 96 fixed to each other. The two driving gears 94 mesh, and one of the driving gears 94 is fixed to the outer surface of the connecting shaft 7. A driving motor is fixed to the top side of the pressure plate 6, and the driving motor is fixed to the bottom side of the other driving gear 94. Specifically, there are two horizontal plates 91, and a rotating plate 95 is fixedly installed on the outer surface of the connecting shaft 7. The two connecting arms 96 are hinged to the two horizontal plates 91 facing each other and to both ends of the rotating plate 95. It should be noted that the driving motor rotates in both directions, causing the two horizontal plates 91 to move relative to each other and away from each other, thereby achieving a reciprocating striking effect.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the finished cardboard enters the frame 1 through the guide plate 12 inclined on the top side of the frame 1 and falls onto the stacking platform 2. After stacking to a certain height, the correction mechanism 3 arranged opposite to each other on both sides of the frame 1 can correct the position of the cardboard to ensure that the cardboard is stacked neatly. Then, the electric telescopic rod 5 on the gantry frame 4 is activated, and its output end drives the pressure plate 6 to move downward through the connecting shaft 7 to press the stacked cardboard and perform a pressing operation to prevent the cardboard from falling during the stacking process.

[0034] When the pressure plate 6 presses onto the cardboard, the vibration mechanism 9 starts to work. One of the drive gears 94 in the drive assembly rotates with the connecting shaft 7. Since the two drive gears 94 mesh, they drive the other drive gear 94 to rotate. When the connecting shaft 7 rotates, it drives the rotating plate 95 to rotate. The rotating plate 95 drives the two horizontal plates 91 to reciprocate through the connecting arm 96. In the reciprocating assembly 93 on the horizontal plate 91, the reciprocating shaft 931 passes through the horizontal plate 91. The guide roller 934 on the wheel frame on the lower surface of the horizontal plate 91 guides... The guide roller 934 rolls in the wave-shaped guide groove 921 of the seat 92. As the horizontal plate 91 reciprocates, the guide roller 934 rolls in the guide groove 921, causing the reciprocating shaft 931 to reciprocate in the vertical direction. The striking block 932 at the bottom of the reciprocating shaft 931 moves up and down accordingly, continuously striking the pressure plate 6. At the same time, the return spring 933 on the outer surface of the reciprocating shaft 931 helps the reciprocating shaft 931 to return to its original position after being struck, achieving a continuous vibration effect. The vibration can expel the air between the cardboards, making the cardboard stack more compact.

[0035] Finally, when the cardboard is stacked to a certain height or after stacking is completed, the electric telescopic rod 5 drives the pressure plate 6 to move upward and leave the cardboard. Then the sealing door 11 is opened, and the stacking platform 2 is pushed by the push rod 14. Since the inner side of the frame 1 is fixed with the guide rail 13 that slides with the stacking platform 2, the stacking platform 2 can move along the guide rail 13, making it convenient to take out the stacked cardboard.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
