Description

Technical Field

[0001] This utility model relates to the field of blown film machine technology, specifically to an automatic split bubble stabilizer for a self-adhesive multilayer co-extrusion blown film machine. Background Technology

[0002] A blown film machine heats and melts plastic granules, extrudes them into tubular film bubbles through an extruder, and then inflates them with compressed air, cooling them to form a thin film. The key to this process lies in the stability of the film bubble and the cooling effect. The bubble stabilizer, located above the die and below the herringbone plate, is an important component of the blown film machine. It stabilizes and guides the film bubble, preventing it from shaking or deforming, and ensuring a uniform film thickness and a smooth surface.

[0003] Traditional bubble stabilizers have the following problems: The entire ring-shaped structure is manually or synchronously driven by a motor, positioned in a fixed location, and uses multiple rollers for ring-shaped fixation. Excessive roller contact with the film surface can easily cause contamination; when encountering products with high-viscosity protective films, the rollers adhere, causing the film to be deformed under additional tension. Furthermore, the overall height of traditional bubble stabilizers is fixed and cannot be adjusted. During the film blowing process, different formulations may lead to issues such as: insufficient cooling distance, large blow-up ratio, low material viscosity, and inconsistent frosting line height, resulting in significant bubble sway. The bubble process is also susceptible to external wind interference, and the equipment is difficult to adjust flexibly according to production needs, leading to poor film thickness uniformity. The same machine cannot adapt to different formulations, resulting in low production flexibility.

[0004] Therefore, it is of great significance to provide a dedicated automatic split bubble stabilizer for self-adhesive multilayer co-extrusion blown film machines to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an automatic split bubble stabilizer for a self-adhesive multilayer co-extrusion blown film machine, so as to solve the problems of insufficient stability, poor cooling effect and difficulty in flexibly adjusting according to production needs of traditional A-frame frames.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic split-type bubble stabilizer for a self-adhesive multilayer co-extrusion blown film machine includes a base plate. Support frames are fixedly connected to both sides of the top of the base plate. Two lifting cylinders are fixedly connected to the top and bottom of the inner sides of the two support frames. The four lifting cylinders are grouped together at the same height. A support plate is fixedly connected to the top of each group of lifting cylinders. Rotating rings are rotatably connected to the top of the two support plates. Four adjustment mechanisms are installed between the tops of the two rotating rings.

[0008] The adjustment mechanism includes a fixed plate, a slide rod slidably connected to the fixed plate, a motor mounting plate and a movable plate fixedly connected to both ends of the slide rod respectively, a connecting frame fixedly connected to the motor mounting plate and the movable plate, and an anti-stick roller installed on the side of the movable plate.

[0009] Preferably, a servo motor is mounted on the top of the motor mounting plate, and a lead screw is threadedly connected to the middle of the fixed plate. The two ends of the lead screw are rotatably connected to the motor mounting plate and the movable plate, respectively.

[0010] Preferably, a transmission pulley is fixedly connected to the end of the lead screw, and a drive pulley is driven to the output end of the servo motor. The drive pulley and the transmission pulley are connected by a transmission belt.

[0011] Preferably, the outer ring of the rotating ring is provided with a toothed ring, the bottom end of the support plate is equipped with a rotating motor, the output end of the rotating motor is connected to a transmission gear, and the transmission gear is connected to the toothed ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model is equipped with a two-layer adjustment mechanism and a lifting cylinder that drives the mechanism. In use, each set of adjustment mechanisms can be freely adjusted in height according to the type and specifications of the film bubble, thereby meeting the production needs of different types of films. When blowing film at high speed, it can extend the contact time of the film bubble that has not been cooled and shaped in time with the roller, so that the film bubble can be better shaped.

[0014] The double-layer adjustment mechanism of this invention can drive the anti-sticking roller to gather and disperse, thus making it suitable for the production of films of different sizes;

[0015] The adjustment mechanism in this invention can rotate at an angle. In use, the rotating motor drives the rotating ring to rotate 90 degrees through the transmission gear, so that the adjustment mechanisms of the upper and lower layers are torn at intervals, thereby modifying the shape of the membrane bubble and making the membrane thickness more uniform.
