Technical Field

[0001] This utility model relates to the field of corrugated cardboard feeding rack technology, and in particular to a feeding rack for corrugated cardboard processing. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. In the mass production process of corrugated cardboard, a feeding rack is usually used to transport and feed the cardboard.

[0003] The existing feeding racks have the following shortcomings in use:

[0004] In existing corrugated cardboard processing, the cardboard is usually fed by a mobile feeding rack. Before feeding, the stacked cardboard is pressed down by a pressing device to prevent the cardboard from slipping due to vibration during the movement. However, the pressing device is usually fixed in one position. Since the cardboard has different sizes, it is not convenient to flexibly adjust the pressing device, making it inconvenient to press and fix cardboard of different sizes. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, corrugated cardboard is usually fed by a mobile feeding rack. Before feeding, the stacked cardboard is pressed down by a pressing device to prevent the cardboard from slipping due to vibration during the movement. However, the pressing device is usually fixed in one position. Since cardboard has different sizes, it is not convenient to flexibly adjust the pressing device, making it inconvenient to press and fix cardboard of different sizes. Therefore, this utility model proposes a feeding rack for corrugated cardboard processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding rack for corrugated cardboard processing includes a base and a placement box for placing cardboard. A frame is fixedly installed on the top of the base, and a concave plate is rotatably installed on the top of the frame. Universal casters are fixedly installed at the four corners of the bottom of the base for easy movement. The placement box is provided with a pressing mechanism, which can press down and fix the cardboard after it is stacked to prevent it from slipping during the feeding process.

[0008] In order to adjust the pressing mechanism, the placement box also includes an adjustment mechanism that can adjust the position of the pressing mechanism to facilitate pressing of cardboard of different sizes;

[0009] To facilitate unloading, the placement box also includes an ejection mechanism that can push out the stacked cardboard when it is transported to the unloading position.

[0010] In one possible design, the pressing mechanism includes a fixed frame, a first electric push rod, and a pressure plate. The fixed frame is U-shaped, one end of the first electric push rod is fixedly connected to the top of the fixed frame, and the telescopic part of the first electric push rod passes through the top of the fixed frame and is fixedly connected to the top of the pressure plate. The length of the pressure plate is the same as the inner diameter of the placement box.

[0011] In one possible design, the adjustment mechanism includes a connecting block, a third electric push rod, and a movable plate. The bottom of the placement box has a first through hole, and the placement box has a second through hole that communicates with the first through hole. The outer side of the movable plate is slidably connected to the inner wall of the second through hole. The connecting block is located inside the first through hole and its top is fixedly connected to the bottom of the movable plate. A fixing block is fixedly installed on one side of the bottom of the placement box. The fixing part of the third electric push rod is fixedly connected to one side of the fixing block. The telescopic part of the third electric push rod is fixedly connected to one side of the connecting block. The two ends of the fixing frame are respectively fixedly connected to the top two sides of the movable plate.

[0012] In one possible design, the ejection mechanism includes a second electric push rod and a push plate. The bottom of the push plate is slidably connected to the bottom inner wall of the placement box. One end of the second electric push rod is fixedly connected to one side of the placement box. The telescopic part of the second electric push rod passes through one side of the placement box and is fixedly connected to one side of the push plate.

[0013] In one possible design, a lead screw for adjusting the height of the placement box is rotatably connected to the bottom inner wall of the concave plate, and a first motor for driving the lead screw to rotate is fixedly installed on the top of the concave plate. The output end of the first motor passes through the top of the concave plate and is fixedly connected to the top end of the lead screw. A moving block is slidably connected to the inner wall of one side of the concave plate. A lead screw nut is embedded in one side of the moving block. The lead screw nut is threadedly connected to the lead screw. One side of the moving block is fixedly connected to one side of the placement box.

[0014] In one possible design, a second motor for adjusting the angle of the placement box is fixedly installed on the top inner wall of the frame. The output end of the second motor passes through the top of the frame and is fixedly connected to the bottom of the concave plate. An annular hole is provided on the frame, and a rod for improving the stability of the concave plate is provided in the annular hole. The rod is T-shaped, and the bottom end of the rod is fixedly connected to the bottom of the concave plate.

[0015] In one possible design, the lead screw is fitted with two lead screw protective covers for dust prevention. The ends of the two lead screw protective covers that are far apart from each other are fixedly connected to the top inner wall and the bottom inner wall of the concave plate, respectively, and the ends of the two lead screw protective covers that are close to each other are fixedly connected to the top and bottom of the moving block, respectively.

[0016] In this application, during use, cardboard is stacked and placed into the placement box, adhering to the push plate and one side of the inner wall of the placement box. After the cardboard is stacked, the third electric push rod is activated. The telescopic part of the third electric push rod pushes the connecting block and the moving plate to slide within the second through hole. The moving plate drives the fixed frame and the pressure plate to move, thereby adjusting the position of the pressing mechanism to press cardboard of different sizes. Then, the first electric push rod is activated. The telescopic part of the first electric push rod pushes the pressure plate downward until the pressure plate is in close contact with the cardboard stack, completing the pressing and fixing to prevent the cardboard from slipping during the moving and feeding process. Then, the whole unit is pushed and moved by the universal wheels (the universal wheels are lockable universal wheels) to feed the cardboard. After being transported to the position (e.g., the workbench), the second motor is activated. The output end of the second motor drives the concave plate to rotate, thereby adjusting the angle of the placement box so that the placement box is positioned in the direction of the workbench. Then, the first motor is activated. The output end of the first motor drives the lead screw. Rotating the screw causes the moving block to slide along the inner wall of one side of the concave plate, thereby adjusting the height of the placement box to accommodate processing equipment or workbenches of different heights. After adjusting to the appropriate height and aligning with the workbench surface, the second electric push rod is activated. The telescopic part of the second electric push rod pushes the push plate to slide along the bottom inner wall of the placement box, smoothly pushing out the stacked cardboard for easy unloading. The screw is protected by a screw guard (the screw guard is telescopic). The first and second motors can be stepper motors or conical rotor motors, and the type of motor can be selected according to actual needs. The type, material, and specifications of the screw can also be selected according to actual needs. It should be noted that the first motor, second motor, first electric push rod, second electric push rod, and third electric push rod require an external controller (such as a PLC controller) and an external power supply. The power supply can be a battery installed on the base.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, the feeding rack for corrugated cardboard processing, through the adjustment mechanism, activates the third electric push rod. The telescopic part of the third electric push rod pushes the connecting block and the moving plate to slide in the second through hole. The moving plate drives the fixed frame and the pressure plate to move, thereby adjusting the position of the pressing mechanism to facilitate pressing cardboard of different sizes.

[0019] In this utility model, the feeding rack for corrugated cardboard processing uses an ejection mechanism to activate a second electric push rod. The telescopic part of the second electric push rod pushes the push plate to slide on the bottom inner wall of the placement box, smoothly ejecting the stacked cardboard for convenient unloading.

[0020] In this invention, the position of the pressing mechanism can be flexibly adjusted according to different sizes of cardboard through the adjustment mechanism. The setting of the ejection mechanism allows the cardboard to be smoothly ejected by the push plate pushed by the second electric push rod when it is transported to the unloading position, realizing convenient unloading. This design improves work efficiency, reduces manual operation, and reduces labor intensity. Attached Figure Description
