AI Technical Summary
The bubble stabilizing frame of existing blown film machines is prone to deviation when adjusting the position of the bubble stabilizing roller, which leads to unstable film bubbles and affects film quality.
An adjusting disc is used to control the movement of multiple bubble stabilizing sections. The connecting rod is pushed by an arc groove to achieve synchronous adjustment of the bubble stabilizing roller, ensuring the stability of the bubble center position.
This ensures that the central axis position of the bubble stabilizing roller remains unchanged under different bubble diameters, avoiding deviations and guaranteeing the stability of the bubble and the quality of the film.

Abstract
Claims
1. A bubble stabilizer for a blown film machine, characterized by, It includes: Mounting platform (1), the mounting platform (1) includes an annular fixed platform (11) and support feet (12) connected to the edge of the annular fixed platform (11). The inner side of the annular fixed platform (11) is provided with a membrane bubble channel (101) for the membrane bubble generated by the blown film machine to pass through. The annular fixed platform (11) is provided with a plurality of radial grooves (102), the radial grooves (102) extending radially along the annular fixed platform (11). The bubble stabilizing section (2) is provided in a one-to-one correspondence with the radial groove (102). The bubble stabilizing section (2) includes a slide (21) and a connecting rod (22). Each slide (21) is slidably connected in the corresponding radial groove (102). The connecting rod (22) is fixed on the slide (21). The two ends of the connecting rod (22) extend in the vertical direction perpendicular to the plane of the annular fixed platform (11). Multiple bubble stabilizing rollers (221) for abutting the outer periphery of the membrane bubble are connected on the connecting rod (22). Each bubble stabilizing roller (221) extends laterally parallel to the annular fixed platform (11). Each bubble stabilizing roller (221) on the same connecting rod (22) is located at a different height. An adjusting plate (3) is mounted above an annular fixed platform (11). The adjusting plate (3) has a membrane bubble clearance opening (301) and multiple arc grooves (302). The projection of the membrane bubble clearance opening (301) on the annular fixed platform (11) coincides with the membrane bubble channel opening (101). The multiple arc grooves (302) extend in a vortex shape to the outer periphery of the membrane bubble clearance opening (301). Each arc groove (302) is fitted onto the connecting rod (22) in a corresponding manner. The adjusting plate (3) is used to push the connecting rod (22) by rotating the arc grooves (302), thereby causing the connecting rod (22) to move along the radial groove (102) with the slide (21).
2. The bubble stabilizing table of a film blowing machine according to claim 1, characterized in that, A rotating handle (31) is fixed on the outer circumferential surface of the adjusting disc (3).
3. The bubble stabilizing table of a film blowing machine according to claim 1, characterized in that, The adjusting disc (3) is provided with a worm gear (32), and a worm is provided on the worm gear (32) to mesh with it. The worm is connected to the output shaft of the drive motor and is used to drive the adjusting disc (3) to rotate.
4. The bubble stabilizing table of a film blowing machine according to claim 1, characterized in that, The projections of adjacent bubble stabilizing rollers (221) on the connecting rod (22) on the annular fixed platform (11) do not overlap, and the projections of different bubble stabilizing rollers (221) on the same horizontal plane on multiple connecting rods (22) on the annular fixed platform (11) are not parallel.
5. The bubble stabilizer of the blown film machine according to claim 1, characterized in that, Multiple bubble stabilizing rollers (221) on the same connecting rod (22) are symmetrically arranged on the upper and lower sides of the annular fixed platform (11).
6. The bubble stabilizing table of a film blowing machine according to claim 1, characterized in that, A sleeve (211) is fixed on the slide block (21). The sleeve (211) has a positioning screw hole (210) facing the sliding direction of the slide block (21). The connecting rod (22) is inserted into the sleeve (211) and locked with the positioning screw hole (210) by a screw.
7. The bubble stabilizing table of a film blowing machine according to claim 1, characterized in that, The bubble stabilizing roller (221) includes a roller shaft and a roller rotatably mounted on the roller shaft.
