Problems solved by technology

[0002] The contact surface between the folding roller and the vacuum valve block of the existing handkerchief paper folding machine is due to relative motion (the folding roller makes a rotary motion, while the vacuum valve block is fixed on the vacuum chamber and is relatively stationary, when the suction port of the folding roller is aligned When the opening part of the vacuum valve block is opened, the folding roller absorbs the handkerchief paper and turns to the folding position, thereby completing the folding action of the handkerchief paper) so their contact surfaces are worn due to friction, because the material for making the vacuum valve block is tin bronze, The material of the folding roller made of 45# steel is softer, so the vacuum valve block is easier to wear, and generally needs to be replaced once a year

Embodiment 1

[0020] A folding roller assembly with reduced wear, the structure of which is as follows figure 1 As shown, it includes: a folding roller 2 sleeved on the shaft body 1, the folding roller 2 extends into the vacuum chamber 6, a suction port is opened on the folding roller 2, and a vacuum valve block fixed in the vacuum chamber 6 5. The vacuum valve block 5 is provided with openings. When the suction port of the folding roller 2 is aligned with the opening of the vacuum valve block 5, the folding roller 2 sucks the handkerchief paper and turns to the folding position, thereby completing the folding action of the handkerchief paper. The folding roller 2 is made of 45# steel, and the vacuum valve block 5 is made of tin bronze. Due to the difference in hardness between the two, if they are in direct contact, long-term relative movement will cause the contact surface 4 to wear.

[0021] In order to solve this problem, in this embodiment, the vacuum valve block 5 is equipped with a ...

Embodiment 2

[0024] A folding roller assembly with reduced wear, its structure is roughly the same as that of Embodiment 1, the difference is that the distance between the vacuum valve block 5 and the folding roller 2 is controlled at 0.15mm.

Abstract

The invention relates to a folding roller assembly capable of lowering abradability. The folding roller assembly comprises a folding roller (2) arranged on a shaft body (1) in a sleeving manner and avacuum valve block (5), wherein the folding roller (2) stretches into a vacuum air chamber (6); a suction port is formed in the folding roller (2); the vacuum valve block (5) is fixed in the vacuum air chamber (6); an opening hole is formed in the vacuum valve block (5); a bearing (7) is arranged in the vacuum valve block (5); a check ring (3) is arranged between the folding roller (2) and the inner ring of the bearing (7); and the check ring (3) is arranged on the shaft body (1) in a sleeving manner to enable the vacuum valve block (5) to be separated from the the folding roller (2) by certain distance. Compared with the prior art, the folding roller assembly effectively controls the distance between the folding roller and the vacuum valve block to solve the problem about abrasion of thecontact surface of the folding roller and the vacuum valve block.

Description

technical field [0001] The invention relates to a folding roller, in particular to a folding roller assembly with reduced wear. Background technique [0002] The contact surface between the folding roller and the vacuum valve block of the existing handkerchief paper folding machine is due to relative motion (the folding roller makes a rotary motion, while the vacuum valve block is fixed on the vacuum chamber and is relatively stationary, when the suction port of the folding roller is aligned When the opening part of the vacuum valve block is opened, the folding roller absorbs the handkerchief paper and turns to the folding position, thereby completing the folding action of the handkerchief paper) so their contact surfaces are worn due to friction, because the material for making the vacuum valve block is tin bronze, The material of the folding roller made of 45# steel is softer, so the vacuum valve block is easier to wear, and generally needs to be replaced once a year.
