Problems solved by technology

[0004] In the portable label printers in the prior art, since the surface of the rubber roller is made of rubber material, it will stick to the sticky label paper. Therefore, the existing label paper printers can generally only be used for printing labels with backing paper, or the surface Printing on non-adhesive linerless label paper

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] A new type of anti-sticking rubber roller, such as figure 2 and image 3 As shown, it includes a roller shaft 1 and a coating layer 2. The coating layer is coaxially wrapped around the outer edge of the roller shaft. The outer surface; The rubber can be any one of natural rubber, nitrile rubber and polyurethane rubber;

[0020] There are two ways to alternate: one such as image 3 As shown, the rubber strips 4 and the silicone rubber strips 3 are arranged at intervals and pasted on the outer surface of the roller shaft, and the other is that the rubber blocks are embedded on the outer surface of the silicone rubber coating layer at intervals, and the surface is smooth.

[0021] The silicone rubber is added with polymethylvinylsilsesquioxane spherical micropowder in the silicon mixing silicone rubber, and the surface of the vulcanized...

Abstract

The invention discloses a novel anti-stick rubber roller. The novel anti-stick rubber roller comprises a roll shaft and a coating layer; the coating layer is composed of rubber and silicone rubber inan alternating mode and is arranged on the outer surface of the roll shaft in a coating mode; the rubber can be any kind among natural rubber, acrylonitrile-butadiene rubber and urethane rubber; and according to the silicone rubber, polymethyl ethylene base silicon sesquialter oxane spherical powder is added in silicon mixed silicone rubber, and after vulcanization, the surface of the rubber roller is free of adhesion and friction coefficient is low. The surface distribution area of anti-stick materials and a rubber materials are adjusted to adjust the relationship between friction and stick resistance, the requirements that the friction enables a tagboard to be transmitted and the stick resistance enables the tagboard to be unbonded are met, and the problem that a bottomless tagboard cannot be printed by portable printers is solved.

Description

technical field [0001] The invention relates to the field of printers, in particular to a novel anti-adhesive rubber roller suitable for a portable bottomless label printer. Background technique [0002] Traditional self-adhesive label materials include three parts: surface substrate, adhesive and backing paper. The linerless label, as the name implies, is a self-adhesive label without a liner. Linerless label stock has a release coating on the surface and an adhesive on the back. [0003] Linerless labels have the distinct advantage of reducing waste. In addition, linerless labels offer cost savings in terms of storage, shipping and application. Because there is no backing paper, the paper roll of the same size can accommodate more labels, which can reduce the cost of a single label and reduce the frequency of paper replacement. More labels per roll means less weight for storage and transport, less label stock, significantly less waste on printing presses and packaging ...
