Description
Technical Field
[0001] This utility model relates to the field of printing technology, and in particular to a rigid paper transfer and lifting tool. Background Technology
[0002] In printing operations, to meet customers' customized needs, covers are often made of rigid paper. During printing, these papers are pre-stacked on a feeding platform and then fed by an automatic feeding device. During feeding, it is crucial to ensure that the paper's movement direction is strictly parallel to its length direction; any misalignment will result in misaligned printing positions. To ensure print quality, the neatness and orientation of the paper after placement are critical. Currently, operators place the stacked cardboard on the feeding platform and then use methods such as tapping with a flat plate to ensure neat stacking. However, this method has significant limitations, and paper transfer and feeding often involve operators hugging the paper, which can easily lead to uneven paper distribution. Utility Model Content
[0003] This utility model provides a rigid paper transfer and lifting tool to overcome the shortcomings of the prior art and solve the problem of uneven paper stacking caused by feeding, which has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A rigid paper transfer and lifting device includes a pair of end supports, which are respectively disposed at both ends of the paper along its length. The lower ends of the end supports are connected by a connecting part located below the stacked paper. The upper ends of the end supports are connected by a lifting part located above the stacked paper. Limiting parts are provided on both sides of the lifting part, located on both sides of the paper along its width, and the lower ends of the limiting parts are connected to the end supports.
[0005] Furthermore, the end support includes a bottom support plate, which is a long strip structure, and the length direction of the bottom support plate is parallel to the width direction of the paper. The outer end of the bottom support plate is bent upward to form a constraint end plate, which is located at both ends of the paper in the length direction to limit the ends of the paper in the length direction. A pair of upper extension support plates are welded to the upper end of the constraint end plate, and a connecting end plate is bent outward at the upper end of the upper extension support plate. A pair of connecting pins are welded to the connecting end plate.
[0006] Furthermore, the lifting part includes a horizontal plate, the length direction of which is parallel to the length direction of the paper. Concave plates are welded to the ends of the horizontal plate, and two pairs of waist-shaped holes are provided on the concave plates. The length direction of the waist-shaped holes is parallel to the length direction of the paper. The connecting pins correspond one-to-one with the waist-shaped holes, and the connecting pins are movably disposed in the waist-shaped holes. The lower wall of the end cap of the connecting pin abuts against the upper wall of the concave plate.
[0007] Furthermore, a pair of lower convex plates are welded to the lower wall of the base plate, and a pair of rollers are mounted on the lower end of the lower convex plates via a wheel axle.
[0008] Furthermore, a pair of concave handles are welded onto the horizontal plate.
[0009] Furthermore, the connecting part includes a pair of lower locking pins welded to the lower wall of the base plate. The lower wall of the base plate is provided with a lower baffle. The upper wall of the lower baffle is formed with a boss. One end of the lower baffle is provided with a pair of U-shaped grooves. The lower locking pins pass through the U-shaped grooves, and the upper end of the cap of the lower locking pins abuts against the lower wall of the lower baffle. The other end of the lower baffle is provided with a pair of elongated holes. The inner end of the elongated holes is provided with an end round hole. The width of the elongated holes is smaller than the diameter of the end cap of the lower locking pins, and the diameter of the end round hole is larger than the diameter of the end cap of the lower locking pins. The lower locking pins pass through the elongated holes to support the paper at the bottom. The lower baffle is bent downward at one end of the elongated holes to form a lower extension plate.
[0010] Furthermore, the limiting part includes locking pins welded to both ends of the lower wall of the base plate. A side support strip is provided below the base plate. The inner sides of both ends of the side support strip are provided with slots. The rod part of the locking pin passes through the slot. The upper end of the end cap of the locking pin abuts against the lower wall of the side support strip. A pair of side baffles are welded to the outer wall of the side support strip. The upper end of the side baffle is bent outward to form a fixed upper plate. A pair of upper extension pins are welded to the fixed upper plate. Two pairs of connecting screws are connected to the horizontal plate by threads. A movable plate is movably provided on each pair of connecting screws. A pair of moving holes are provided on the movable plate. The connecting screws pass through the moving holes. The lower end of the end cap of the connecting screw abuts against the upper wall of the movable plate. A pair of wing plates are welded to both sides of the movable plate.

The rod part of the upper extension pin passes through the connecting slot, and the lower end of the end cap of the upper extension pin abuts against the upper wall of the wing plate.
[0011] The advantages of the above technical solution are: This invention uses multiple limiting components to limit the paper in four directions to ensure the neatness of the paper stacking after feeding. The end support plays a limiting and constraining role at both ends of the paper in the length direction, while the limiting part plays a constraining role at both sides of the paper, thus ensuring the neatness of the paper stacking during feeding.
[0012] This invention also facilitates the transfer of stacked paper, preventing paper displacement during the transfer and feeding process, which could negatively impact subsequent paper feeding and increase the number of papers transferred during feeding.
[0013] This invention allows for easy separation from the paper after feeding, minimizing any negative impact on the neatness of the paper stacking. Attached Figure Description
