Description

Technical Field

[0001] The utility model relates to the technical field of film blowing, in particular to film blowing equipment for processing plastic garbage bags. Background Art

[0002] Film blowing machine is a kind of plastic mechanical equipment that heats and melts plastic particles and then blows them into thin films. It is an indispensable mechanical product in the production process of modern plastic products. There are many types of film blowing machines, such as PE film blowing machine, POF film blowing machine, etc. Its application range is mainly determined by the different materials. For example, the film produced by PP film blowing machine is suitable for various supermarket shopping bags, fungus bags and other bags with relatively high hardness and low requirements for stretchability and brightness, while the film blown by high-pressure PE is suitable for various fresh-keeping bags.

[0003] Common film blowing machines are mainly composed of an extruder, a machine head, a die head, a cooling device, a bubble stabilizing frame, a herringbone plate, a traction roller, a winding device, etc. When the film blowing machine is working, the plastic particles are heated and melted, and made into a film through extrusion and stretching, and then processed into plastic products of the required shape and size through cooling, shaping, cutting and other processes.

[0004] However, in this method, after the plastic film is blown, it needs to be stretched by a traction device and then rolled up by a winding mechanism. Since the film is soft in texture, it is easy to drag during traction, which causes overlapping during rolling, etc., reducing the quality of the plastic garbage bag film blowing and failing to meet the working requirements of the plastic film blowing. Therefore, a film blowing equipment for processing plastic garbage bags is proposed. Utility Model Content

[0012] Preferably, a hinge block is installed on the left side of the top of the adjustment sleeve, and the right end of the connecting arm is inserted into the interior of the hinge block through a bearing. The connecting arm is made of steel, which improves the strength of the connecting arm and prevents bending or breakage.

[0013] Preferably, a winding mechanism is installed on the upper left side of the body shell, a mounting frame is installed on the lower left side of the body shell, and support columns are welded to the left front and rear of the mounting frame to facilitate supporting the rolled film.

[0014] Preferably, the interior of the support column is a hollow structure, and a supporting rod is inserted into the upper side of the interior of the support column. A limiting roller is laterally welded to the top of the supporting rod. The length of the limiting roller is greater than that of the winding mechanism, thereby improving the stability of the support for the winding film.

[0015] Preferably, a disc is coaxially mounted at the bottom end of the supporting rod, a spring is connected to the bottom of the inner cavity of the supporting column, and the top of the spring is connected to the bottom of the disc, so that the limiting roller can expand and contract as the film becomes thicker, so that the limiting roller can always be in close contact with the surface of the film.

[0016] Compared with the prior art, the utility model provides a film blowing device for processing plastic garbage bags, which has the following beneficial effects:

[0017] The film blowing equipment for processing plastic garbage bags drives the movement of the transmission rod and the plug block by rotating the hand wheel, thereby pushing the adjustment sleeve to move left and right on the surface of the connecting shaft, so that the assembly parts and the connecting plate can be driven to tilt through the connecting arm, and then the surface of the plastic film can be pushed and pulled to the right through the pressure roller, so that the dragging film can be stretched, preventing the problem of overlapping or tilting after the film is blown, and improving the quality of the film blowing process.
