Problems solved by technology

However, in production practice, due to the influence of factors such as printing process and raw materials, no matter it is thin paper or thick paper, there is a phenomenon of paper curling, especially for thin paper with specifications below 100 g / m2
If the paper is curled up, humidification is usually used to improve it, but the effect is still not ideal; if the paper is curled down, it cannot be solved under the current technical conditions.
The curl of the paper affects the appearance quality of the product, resulting in an increase in the scrap rate, and at the same time has a great impact on the applicability of the customer's product

Embodiment Construction

[0019] The following examples illustrate the present invention in more detail, but are not limited to the following examples as long as it falls within the scope of the present invention.

[0020] A paper anti-curl device, which consists of a paper guide roller (1), a reverse roller (2), a wallboard (3), a locking screw (4), and a bearing seat (5). The paper guide roller (1) is fixed on the wallboard (3) through the locking screw (4), the reverse roller (2) is located obliquely below the paper guide roller (1), the reverse roller (2) and the bearing seat (5 ) are connected, and the bearing seat (5) is fixed on the wallboard (3).

[0021] In this embodiment, the ratio of four paper guide rollers and three reverse rollers is taken as an example: during operation: the roll paper is wound from top to bottom through the upper surface of the first paper guide roller (1) to the lower surface, and then The upper surface of the first reverse roller (2) is wound to the lower surface, a...

Abstract

The invention provides a device for preventing paper curling. The device comprises paper guide rollers (1), reversing rollers (2), wallboards (3), locking screw rods (4) and bearing bases (5). The paper guide rollers (1) are fixed on the wallboards (3) via the locking screw rods (4). Each reversing roller (2) is located under the corresponding paper guide roller (1) sidewise. The reversing rollers (2) are connected with the bearing bases (5). The bearing bases (5) are fixed to the wallboards (3). The device is scientific in design, simple in structure, convenient to install, rapid to maintain and good in curling preventing effect, and can increase the percent of pass of products. The device widely meets the working requirements for paper curling prevention in the printing industry, is a great help in the domestic printing industry and is worthy of vigorous promotion.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a paper anti-curling device. Background technique [0002] At present, in the printing field of our country, the printing of cigarette pack paper occupies more than half of the market. Under normal circumstances, the processing of thin paper after printing is suitable for rotary cutting machine, and the roll paper rotary cutting machine generally consists of unwinding - deviation correction - first-level traction - second-level traction - die-cutting - —Comprised of six main processes such as finished product collection, thick paper is suitable for paper cross-cutting machines. However, in production practice, due to the influence of factors such as printing process and raw materials, there is a phenomenon of paper curling, whether it is thin paper or thick paper, especially for thin paper with specifications below 100 g / m2. If the paper is curled up, humidification is usually...
