Embodiment Construction

[0015] Such as figure 1 As shown, a belt roller 1 is respectively set on the left and right, wherein the belt roller on the right comprises a roller shaft 2, a cone core 8, and a matching taper sleeve 6 is arranged on the periphery of the cone core 8, and an elastic jacket 7 is arranged on the periphery of the cone sleeve 6, The cone core 8 is set on the periphery of the roller shaft 2, and the outer wall of the cone core 8 increases linearly from left to right, and the taper of the outer wall is 4-10 degrees, and the optimum value is 5 degrees. Taper sleeve 6 has a section of inner cavity which is a conical tube complementary to the outer wall of cone core 8, and its inner wall increases linearly from left to right. The tail end of the cone core 8 extends into the tapered tube to the left, and the outer periphery of the large end of the cone sleeve 6 is an elastic jacket 7 coaxial with the roller shaft 2. The right section of core is head end 15, and head end 15 periphery i...

Abstract

The invention relates to a paper feeding speed difference adjusting mechanism for a sheet-fed paper guide, which comprises a belt roller and a roll shaft, and is characterized in that: the belt roller consisting of a taper core sleeved outside the roll shaft, a taper sleeve sleeved outside the taper core and an elastic sleeve sleeved outside the taper sleeve is arranged in the belt roller; the taper core and the taper sleeve are in same-taper complementary sleeve, and the wall of the taper sleeve is provided with a plurality of axially parallel wall seams; and the head end of the taper core is provided with an adjusting gear set for adjusting the radial size of the taper sleeve. Through the rotary adjustment of the meshed gear set of a handle, the taper core is pushed to displace on the roll shaft to adjust the change of the radial size of the big end of the taper sleeve to change the running speed of the belt roller, so as to adjust the linear speed of one side of paper, make the speeds of the left and right two sides of the paper consistent, allow a paper guide to smoothly feed paper at a high speed and improve the quality of printed products.

Description

technical field [0001] The invention relates to a paper feeding speed difference adjusting mechanism, in particular to a paper feeding speed difference adjusting mechanism of a sheet-fed paper feeding machine. Background technique [0002] During the feeding process of the sheet-fed paper feeder, when the paper reaches the front gauge of the paper feeding board, the paper will be fast on one side and slow on the other, and the two ends will not be parallel. Reasons, such as machine vibration, external influences, etc., will cause the speed of the left and right sides of the paper to be inconsistent when passing through the paper feeding board. When the paper reaches the front gauge, it has been seriously distorted. Therefore, it is urgent to design an adjustment mechanism for paper skew. When the paper feeder reaches high-speed paper feeding, by changing the linear speed of one end of the paper, the speed of the left and right ends of the paper can be consistent, so that th...
