Online diameter regulation device for roll paper folding machine

Abstract

The invention relates to an online diameter regulation device for a roll paper folding machine. The online diameter regulation device is characterized in that a main shaft is arranged on a rotating rack between a front bearing and a rear bearing, a pull rod is mounted in the main shaft in a sliding manner, a front end disc and a rear end disc are fixed on the main shaft, a front guiding trough is formed in the rear side wall of the front end disc along the radial direction of the front end disc, a rear guiding trough is formed in the front side wall of rear end disc along the radial direction of the rear end disc, a support rod is bridged between the front guiding trough and the rear guiding trough in a sliding manner, an arc-shaped plate is fixed on the support rod, idler wheel pins are mounted on the support rod, and idler wheels are mounted on the idler wheel pins; a sliding sleeve is sleeved on the main shaft in a sliding manner and is connected with the pull rod, a sliding sleeve axial movement anti-rotation and guiding mechanism is arranged between the sliding sleeve and the main shaft, a titled trough seat is fixed on the outer circle of the sliding sleeve, titled troughs are formed in the titled trough seat, and the idler wheels are mounted in the titled troughs. After the online diameter regulation device is mounted and used, a paper tape can form a proper tension, the folding precision is improved, and an operator can carries out online regulation, so that not only is the regulation efficiency improved, but also the wasting of paper is reduced.

Description

technical field [0001] The invention relates to a device used on a roll paper folding machine, in particular to an online diameter adjusting device of the roll paper folding machine. Background technique [0002] The diameter adjusting device of the existing folding machine such as image 3 , Figure 4 , Figure 5 and Figure 6 As shown, the arc-shaped plates 20' are respectively installed on four radially distributed square rods 8'. When the diameter needs to be adjusted, first loosen the screws 7' at both ends of each square rod, and then loosen the front baffle 5' and the fastening bolt 4' of the backstop 10'. Move the front baffle plate 5' and the rear baffle plate 10' along the circumferential direction respectively. It should be noted that the direction and distance of the baffle must be exactly the same, otherwise the front and rear diameters of the drum will be different. After adjusting, tighten the fastening bolt 4', then tighten the screw 7', so that the shaft...
