Embodiment 1

[0045] Embodiment one is basically as attached Figure 1 to Figure 5 Shown:

[0046] combine figure 1 , a thin-walled tube anti-sway device, including a frame 1, a lower anti-sway unit 2, an upper anti-sway unit 3 and two drive units 4, and the upper anti-sway unit 3 is located between the lower anti-sway unit 2 and the herringbone plate ( Word plate is not marked in the figure), drive unit 4 is all installed on the bottom anti-shake unit 2 and the top anti-shake unit 3, and the bottom anti-shake unit 2 and the top anti-shake unit 3 are installed on the frame 1.

[0047] combine figure 1 with figure 2, the lower anti-sway unit 2 includes a lower frame 5, an adjustment shaft 6 and four anti-sway groups 7, the lower frame 5 is fixedly connected to the frame 1 by bolts, the number of adjustment shafts 6 is six, and the adjustment shafts 6 are arranged vertically And the rotation is connected on the lower frame 5; four groups of anti-sway groups 7 are vertically distributed (...

Embodiment 2

[0057] Embodiment two is basically as attached Figure 6 to Figure 8 Shown:

[0058] Embodiment two is improved on the basis of embodiment one, and in this embodiment two, the quantity of stabilizing group 12 is four groups, and the direction of stabilizing roller 13 of adjacent stabilizing group 12 is opposite (combining Image 6 , in the adjacent two groups of stabilizing groups 12, wherein one group faces clockwise, and the other group faces counterclockwise), the stabilizing roller 13 includes a hollow roller 16 and a turning roller 17, and the turning roller 17 is sleeved on the hollow roller 16, and the turning roller 17 It is connected to the hollow roller 16 through the rotation of the needle, and the outer surface of the rotating roller 17 is wrapped with a water-absorbing cloth 20. Both the rotating roller 17 and the hollow roller 16 are provided with a number of through holes, and the hollow roller 16 is provided with a separator, which will be hollow The roller 16...

Abstract

The invention relates to the technical field of plastic film production, and specifically discloses an anti-shake device for a thin-walled tube, including a frame and a lower anti-shake unit, the lower anti-shake unit includes an anti-shake bar, a drive unit and an upper part above the lower anti-shake unit The anti-sway unit, the upper anti-sway unit includes an upper frame, several rotating shafts and at least one set of stabilizing groups, the rotating shafts are rotatably connected to the upper frame, and the upper frame is fixedly connected to the frame; The height direction of the thin-walled tube is distributed, and each group of stabilizing groups includes a plurality of stabilizing rollers, which surround the thin-walled tube in a circumferential direction, and the stabilizing rollers are detachably connected to the rotating shaft. This solution solves the problem of poor stability of thin-walled tubes in high-end large-scale blow molding units in the prior art by setting the upper anti-shake unit.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to an anti-shake device for a thin-walled tube. Background technique [0002] When a blow molding unit is used to produce blown film, it is necessary to use a thin-walled tube anti-shake device to control the position of the thin-walled tube blown from the machine head. The existing thin-walled tube anti-shake device is installed near the Above the machine head, the position of the upper and lower ends of the thin-walled tube is limited by the anti-shake device of the thin-walled tube and the herringbone plate near the traction roller, and the shaking of the thin-walled tube is prevented, so that the central axis of the thin-walled tube is blown vertically nose. [0003] Most of the anti-sway devices for thin-walled tubes currently used are composed of multi-layer circularly distributed anti-sway bars and a frame for installing the anti-sway bars. During application...
