Description

TECHNICAL FIELD

[0001] The utility model belongs to the auxiliary equipment of blowing film machine especially relates to a blowing film machine air supplementing bubble stabilizing device of full biodegradable product. BACKGROUND

[0002] In the production process of blowing film machine, the film bubble is continuously pulled upward after extruding from the blowing film machine head, and the center position of the film bubble needs to be controlled from deviating or swinging to ensure the smooth operation of the film bubble, so a bubble stabilizer is needed.

[0003] In the blowing film process, the diameter of the film bubble may fluctuate, which may affect the function of the bubble stabilizer in stabilizing the film bubble. For example, when the diameter of the film bubble becomes smaller, the stabilizing rollers may not be able to stably contact the film bubble, the bubble stabilizer cannot effectively support the film bubble, and the film bubble will be eccentric (i.e. the center line of the film bubble deviates from the center line of the head, which is equivalent to deviating from the vertical center axis of the annular fixed frame), affecting the stability of the film bubble. The inner diameter adjustment of the bubble stabilizing device of the blowing film machine on the market is troublesome, needs to be adjusted by a limiting plate, cannot be stably supported in all directions, and has poor effect on stabilizing the film bubble.

The shell includes a lower shell, an upper shell, a slot, and a sliding groove. The upper shell is provided with a slot around its periphery. The lower end of the upper shell is bolted with the lower shell. The upper end of the lower shell is provided with a sliding groove. The sliding groove is slidably connected with the sliding rail of the sliding tooth. The slot is slidably connected with the sliding tooth. The arc-shaped support assembly includes an arc-shaped support column. The arc-shaped support column is symmetrically arranged between the two corresponding sliding teeth.

[0006] As preferred, the gear ring includes a gear ring body, a threaded protrusion, and an annular clamping groove. The lower end of the gear ring body is provided with a threaded protrusion. The threaded protrusion is slidably connected with the threaded tooth at the upper end of the sliding tooth. The outer side of the gear ring body is provided with a tooth. The upper end of the gear ring body is provided with an annular clamping groove. The annular clamping groove is slidably connected with the clamping block at the lower end of the upper shell.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention utilizes a telescopic rib assembly to expand and contract the inner diameter through bending between arc-shaped support columns, thereby stabilizing membrane bubbles of different diameters and ensuring that the center of the membrane bubble does not shift.

[0011] The threaded protrusion at the lower end of the gear drives several sliding teeth to move synchronously, thereby moving multiple arc-shaped support columns closer or further apart to achieve diameter expansion and contraction. At the same time, due to the multiple arc-shaped support columns, better contact with the membrane bubble is achieved, reducing dead angles and preventing the membrane bubble from shifting, resulting in high accuracy.
