Description

Technical Field

[0001] This utility model relates to the field of paper production technology, and in particular to a cutting device for paper production. Background Technology

[0002] Paper is a thin sheet made of plant fibers. It is used for writing, drawing, printing books and newspapers, and packaging. It can be folded at will for writing. Paper is a medium for writing and printing, and it can also be used for other purposes such as packaging and hygiene, such as printing paper, carbon paper, toilet paper, and facial tissue. The paper industry is the industry that produces paper, including the production and processing of paper. In the process of paper processing, cutting and packaging are used.

[0003] In existing paper cutting devices, the paper cannot be fixed during the cutting process, causing the paper to move and deviate from the predetermined trajectory when the cutting blade cuts, resulting in tearing or damage to the paper, which greatly reduces the quality of paper cutting and limits its practicality. Therefore, we propose a paper cutting device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for paper production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, four arc-shaped blocks are fixedly installed on the top of the conveyor frame, and threaded rods are rotatably installed between each pair of corresponding arc-shaped blocks. The outer sides of the two threaded rods are threaded to the inside of the T-shaped moving frame. A support frame is fixedly installed on one side of the conveyor frame, and a No. 3 motor is fixedly installed on the inner side of the support frame. The output end of the No. 3 motor is fixedly connected to one end of the corresponding threaded rod. Synchronous pulleys are fixedly installed on the outer sides of the two threaded rods, and the same synchronous belt is sleeved on the outer sides of the two synchronous pulleys.

[0008] Preferably, T-shaped sliders are fixedly installed on both sides of the movable plate, and T-shaped grooves are opened on both sides of the interior of the T-shaped movable frame, with the outer sides of the two T-shaped sliders slidably connected to the corresponding T-shaped grooves.

[0009] Preferably, a reset spring is fixedly connected to the bottom of each of the multiple connecting blocks, the bottom end of each of the multiple reset springs is fixedly connected to the top of the corresponding pressure plate, and the multiple reset springs are sleeved on the outside of the corresponding guide post.

[0010] Preferably, an arc-shaped support plate is fixedly installed on the inner top of the T-shaped movable frame, and the outer side of the rotating shaft is rotatably installed inside the arc-shaped support plate.

[0011] Preferably, a No. 1 motor is fixedly installed on the front side of the conveyor frame, and the output end of the No. 1 motor is fixedly connected to one end of the corresponding drive shaft.

[0012] In this utility model, a paper cutting device for paper production is described. By starting a second motor, the rotating shaft starts to rotate, which in turn drives the rotating disk to rotate, which in turn drives the rotating rod to rotate, which in turn drives the hinge seat to move vertically, which in turn drives the moving plate to move vertically, and further drives the cutting blades and pressure plate to move vertically. Then, under the action of the guide column and the return spring, the pressure plate contacts the paper first to fix the paper, and then the cutting blades contact the paper later. This prevents the paper from moving during cutting and deviating from the predetermined trajectory, thus preventing tearing or damage to the paper, greatly improving the paper cutting quality and making it more widely applicable.

[0013] In this utility model, a paper cutting device for paper production is described. By starting a No. 3 motor, the threaded rod is driven to rotate, which in turn drives the synchronous wheel to rotate. Through the cooperation between the synchronous belt and the synchronous wheel, the two threaded rods rotate simultaneously, thereby driving the T-shaped moving frame to move along the T-shaped moving groove. This further drives the cutting shears and the pressure plate to move along the T-shaped moving groove, thus facilitating the cutting shears and the pressure plate to cut paper of different lengths.

[0014] This utility model has a reasonable structural design. Through the cooperation between the moving plate, connecting block, guide column, return spring, cutting blade and pressure plate, the pressure plate contacts the paper first to fix the paper, and then the cutting blade contacts the paper. This prevents the paper from moving during cutting and deviating from the predetermined trajectory, thus preventing tearing or damage to the paper. This greatly improves the paper cutting quality and has wider applicability. Attached Figure Description
