Description

Technical Field

[0001] This utility model belongs to the technical field of paper cutting equipment, specifically relating to a roll paper conveying and receiving device. Background Technology

[0002] After being unfolded, cut, and conveyed, the roll of paper enters the receiving process, where individual sheets are stacked one by one onto a paper pallet. Because the cut paper is relatively light, individual sheets often float slightly as they enter the receiving process from the conveying stage, resulting in uneven edges on the stacked paper, which in turn affects subsequent processing or packaging. When the roll of paper needs to be cut longitudinally, it is cut longitudinally simultaneously with the transverse cutting. The paper entering the paper pallet is divided into two stacks, both of which exhibit uneven edges, similarly affecting subsequent processing or packaging.

[0003] To address the above issues, Chinese patent document CN211895386U discloses a paper handling device for paper collection, comprising a frame, a guide rail, a first paper-tapping assembly, a second paper-tapping assembly connected to the frame, and a driving component. The frame is installed on an external paper collection machine, and the guide rail is arranged along the length of the frame. Both the first and second paper-tapping assemblies are slidably connected to the guide rail. Each of the first and second paper-tapping assemblies includes a first slider, a first guide post, and a first correction plate. The first slider is slidably connected to the guide rail, the first guide post is slidably connected to the first slider, and the first correction plate is fixedly connected to the first guide post, located below the guide rail. The driving component is located on the frame and is used to drive the first slider to move. By setting the guide rail, the first and second paper-tapping assemblies, the driving component, the first slider, the first guide post, and the first correction plate, the paper is synchronously trimmed during the paper collection process, resulting in neat stacked paper and improved production efficiency.

[0004] In the aforementioned patent documents, the frame is usually fixed on the paper cutter, and its position cannot be adjusted, making it difficult to achieve the function of collecting paper of different specifications. Utility Model Content

The receiving assembly 22 is used to receive the paper and can gradually descend in the vertical direction to cooperate with the paper aligning assembly 23 to stack the paper into a stack.

[0020] like Figure 4 As shown, the paper alignment assembly 23 includes a paper straightening unit 231 and a rear paper stop unit 232. The paper straightening unit 231 straightens the paper, and the rear paper stop unit 232 stops the paper to prevent it from leaving the paper collection rack 21. The paper straightening unit 231 includes a paper straightening slide rail 2311, two paper straightening slide seats 2312, and several paper straightening components. The two ends of the paper straightening slide rail 2311 are respectively connected to the two paper straightening slide seats 2312, and the several paper straightening components are spaced apart on the paper straightening slide rail 2311. The number of paper straightening components is set according to specific needs. In this embodiment, three paper straightening components are set to achieve the straightening of two stacks of paper.

The second slider 2326 is disposed on the rear paper stop plate 2321, and the second limiting slide rail 2327 is disposed on the rear paper-aligning sliding seats 2322. The lifting cylinder 2325 is used to drive the second slider 2326 to move up and down relative to the second limiting slide rail 2327. The rear paper-aligning slide block 2322 is equipped with a second gear 2323 and a second drive motor assembly 2324. The second gear 2323 meshes with the paper-receiving rack 212, and the output end of the second drive motor assembly 2324 is connected to the second gear 2323. The second drive motor assembly 2324 drives the second gear 2323 to rotate, and the second gear 2323 meshes with the paper-receiving rack 212.
