Problems solved by technology

When printing the film, the rotating shaft or chuck is installed on the inner wall of the paper tube. The printing equipment used is generally high-speed printing equipment. Generally, the speed of domestic printing machines is 150~200m / min, and some imported printing machines are even as high as 250~ 300 m / min, under high-speed printing, the requirements for raw materials are very high. Due to the friction between the film and the rubber roller during high-speed printing, a large amount of static electricity will be generated. At this time, two problems will be caused: 1. It is very easy to cause the film to unwind or when printing Overprinting is not accurate, resulting in a large amount of unnecessary waste, wasting resources and efficiency, resulting in high processing costs; 2. Due to the relative friction between the inner wall of the paper tube and the rotating shaft or chuck, paper dust is generated, resulting in electrostatic adsorption on the film Paper powder phenomenon, these are often not easy to clean up, and then cause bubbles, blurring and other problems after film printing

Embodiment 1

[0023] see figure 1 , 2 , 3, 5, this embodiment provides a new type of anti-off and wear-resistant film paper tube, including a cylindrical paper tube body 1 and an anti-off part 2. The two ends of the body 1 are not closed; the two ends of the body 1 are provided with anti-off parts 2, and the anti-off parts 2 include a ring frame 21 and at least two baffles 22, preferably four in this embodiment. The ring frame 21 and the baffle plate 22 of the anti-off component 2 are integrally formed, and the four baffle plates 22 are evenly distributed along the circumference of the ring frame.

[0024] The anti-loosening component 2 is provided with an annular locking position 23 on the side in contact with the main body 1, and at least two protrusions 24 are arranged on the side of the annular locking position 23 in contact with the inner side of the main body 1, and the protrusions are movable structures. In this embodiment, there are preferably four protrusions 24, which are consis...

Embodiment 2

[0030] As a preferred version of the present invention, see Figure 4 , the outside of the paper tube substrate layer 11 is coated with a first fireproof coating 12 and a second fireproof coating 13 . The first fireproof coating 12 is nitrogen-containing resin, perchlorethylene resin or vinyl chloride copolymer resin, which can release non-combustible gas or fire extinguishing gas when burning in case of fire; the second fireproof coating 13 is phosphorus nitrogen system Flame retardant, when exposed to heat, it produces an endothermic effect, forms a non-volatile covering layer, and blocks the combustion chain. Because the fireproof layer is coated on the outer side of the base layer of the paper tube, the probability of fire is effectively reduced and the loss is reduced.

[0031] Others are the same as embodiment one.

Abstract

The invention relates to an anti-drop wear-resisting novel thin film paper tube. The anti-drop wear-resisting novel thin film paper tube comprises a cylindrical body of which the two ends are non-closed; anti-drop components are arranged at the two ends of the body; each anti-drop component comprises an annular frame and at least two baffle plates; a wear-resisting coating is formed at the inner side of the body and extends from an end portion of the body in the length direction of the body. During height printing, a thin film is effectively prevented from unreeling from the paper tube, the phenomenon that a paper film is adsorbed on the thin film due to electrostatic friction is effectively avoided, and the production quality is improved.

Description

technical field [0001] The invention relates to the technical field of paper tube manufacturing, in particular to a film paper tube used for rolling up film. Background technique [0002] At present, paper tubes are often used in the production and transportation of film products, and the film is wound up on the paper tube. When printing the film, the rotating shaft or chuck is installed on the inner wall of the paper tube. The printing equipment used is generally high-speed printing equipment. Generally, the speed of domestic printing machines is 150~200m / min, and some imported printing machines are even as high as 250~ 300 m / min, under high-speed printing, the requirements for raw materials are very high. Due to the friction between the film and the rubber roller during high-speed printing, a large amount of static electricity will be generated. At this time, two problems will be caused: 1. It is very easy to cause the film to unwind or when printing Overprinting is not a...
