Description

Technical Field

[0001] The utility model belongs to the technical field of paper production, in particular to a paper production and slitting device. Background Art

[0002] Paper is a thin sheet made of plant fiber, mainly divided into letterpress paper, newsprint, offset printing paper, coated paper, book cover paper, dictionary paper, copy paper, board paper, etc. It is one of the most commonly used items in life. In the process of paper production, in order to improve the production efficiency of paper, it is usually necessary to first produce a larger area of ​​roll paper, and then cut the paper through a paper slitting machine. A paper slitting machine is a mechanical equipment used to cut and rewind wide roll paper into rolls of different widths and diameters. The paper slitting machine mainly consists of a frame, a transmission system, a material rewinding and unwinding machine and a tension control device, a traction component, a slitting bracket, a waste rewinding and discharging device, etc. It can mechanize the processing of paper, greatly improve production efficiency, and reduce the labor intensity of staff, but it still has the following disadvantages in actual use:

[0003] The utility model disclosed in the publication number CN216859849U is a high-speed slitting device for paper production and processing, wherein the upper end of the bottom plate is fixedly connected to two symmetrically arranged limit rods, the upper ends of the two limit rods are commonly fixedly connected to a top plate, the two limit rods are slidably sleeved with sleeves, and the two sleeves are commonly fixedly sleeved with a movable plate, and the lower end of the top plate is provided with a lifting mechanism for lifting the movable plate, the lower end of the movable plate is fixedly connected to a fixed plate, the lower end of the fixed plate is provided with a groove, the inner part of the groove is slidably connected with a blade, and the upper end of the blade is fixedly connected with a vertical plate. The high-speed slitting device for paper production and processing can effectively cut paper and improve the production efficiency of paper. However, when the high-speed slitting device for paper production and processing is actually used, the width of the paper is usually cut by one slitting device, and the length of the paper is cut by another slitting device. The two slitting devices occupy a large space and are relatively inflexible to use.

[0004] When a paper production slitting device is slitting paper, since the length and width of a roll of paper are usually large, it can usually slit a large amount of paper or multiple rolls of paper with smaller widths after the slitting process. However, the paper production slitting device can only cut paper of a fixed width at a time when in use. When papers of multiple widths are needed and the demand for papers of multiple widths is different, the staff usually needs to replace the slitting rollers that can cut papers of different widths, which is time-consuming and labor-intensive and may result in excess production of papers of certain widths or sizes. Utility Model Content

[0005] The utility model aims to provide a paper production slitting device, which solves the problem that two or more slitting devices need to be used in combination to cut the paper into specified sizes during the actual production slitting of paper through an operating table, an unwinding component, a slitting motor and a slitting knife holder, which occupies a large space and has poor flexibility in use.

[0018] The utility model has the following beneficial effects:

[0019] The utility model solves the problem that a high-speed slitting device for paper production and processing can effectively cut paper and improve the production efficiency of paper by arranging an operating table, a reeling component, a slitting motor and a slitting knife holder. However, when the high-speed slitting device for paper production and processing is actually used, the width of the paper is usually cut by one slitting device, and the length of the paper is cut by another slitting device. The two slitting devices occupy a large space and are not flexible to use. After the staff cuts the width of the paper by the upper slitting knife and the lower slitting knife, the staff can reel the paper by the reeling component according to production needs, or cut the length of the paper by the slitting knife holder, thereby improving the flexibility of use. The cutting of the width and length of the paper is respectively located on the upper and lower sides of the operating table, which reduces the volume of the slitting device and improves the utilization rate of the space.

[0020] The utility model solves the problem that, when a paper production slitting device slit paper, since the length and width of a roll of paper are usually large, it can usually slit a large amount of paper or multiple rolls of paper with smaller width after slitting processing, while the paper production slitting device can only cut paper of fixed width at a time when in use. When papers of various widths are needed and the demand for papers of various widths is different, the staff usually needs to replace the slitting rollers that can cut papers of different widths, which is time-consuming and labor-intensive and may cause the problem of excess production of papers of some widths or sizes. Before cutting the paper, the staff can clamp multiple sets of upper slitting knives and lower slitting knives at different positions on the outer circumference of the rotating rod according to production needs, so that the slitting device can slitting paper into different widths at a time, thereby improving the flexibility of use, and being able to produce on demand, avoiding the excess production of papers of some sizes and long-term accumulation, and ensuring production efficiency.
