Problems solved by technology

[0003] The two roller surfaces of existing tension rollers are usually in direct contact with each other, so when the tension is high, it is easy to cause slight damage to the structural surface of the coil, resulting in structural line breaks or appearance defects
In addition, the tension rollers clamped in the invalid areas on both sides of the coil are also prone to coil deviation due to poor fixing ability

Embodiment Construction

[0029] In order to make the purpose of the invention, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0030] see figure 1 and figure 2 , The first embodiment of the tension roller of the present invention includes a first roller 10 and a second roller 20 . Wherein, the roll surface of the first roll 10 includes a tension surface 12 positioned in the middle and clamping surfaces 14 positioned on both sides of the tension surface 12. The diameter of the roll in the area is reduced, so that a decompression groove 15 surrounding the tension surface 12 is formed outside the tension surface 12, and the depth of the decompr...

Abstract

A tension roller comprises a first roller (10) and a second roller (20). Roller surfaces of the two rollers (10, 20) both comprise a tension surface (12, 22) located at a center portion thereof and a holding surface (14, 24) located at two sides of the tension surface (12, 22). A roller diameter of a region where the tension surface (12) of the first roller (10) is located is thinned to less than a roller diameter of a region where the holding surface (14) is located, thereby forming a pressure reduction groove (15) outside and around the tension surface (12). The holding surfaces (14, 24) of the first roller (10) and the second roller (20) are opposite to each other. Also provided are a web material (30) suitable for the tension roller, and method for lossless transportation of the web material by using the tension roller. When transporting the web material (30) by using the tension roller, a defect on a structural surface will not be produced by contacting with the first roller (10).

Description

technical field [0001] The invention belongs to the field of coil material transmission, and more specifically, the invention relates to a tension roller, a suitable coil material and a non-destructive transmission method for the coil material. Background technique [0002] In the path of the roll-to-roll device, in order to obtain a stable tension of the coil, it is necessary to set a tension roller in contact with the coil. Tension rollers are generally used in pairs, and the coil passes between the upper and lower rollers to form an S shape, so it is also called an S roller. [0003] The two roll surfaces of the existing tension roll are usually in direct contact with each other, so when the tension is high, it is easy to cause slight damage to the structural surface of the coil, resulting in structural line breaks or appearance defects. In addition, the tension rollers clamped in the invalid areas on both sides of the coil are also prone to cause coil deviation due to p...
