Embodiment 1

[0074] Embodiments of the present invention provide a film blowing equipment suitable for biodegradable materials, such as Figure 1-Figure 3 shown, including:

[0075] A heating box 1, the inner wall of the heating box 1 is provided with several heating rods, the heating box 1 is provided with a feed port 2 and a discharge port 3, and the inside of the heating box 1 is also provided with a stirring shaft 4, and the stirring shaft 4 is provided with a stirring blade 5, the outside of the heating box 1 is provided with a first motor 6, the output shaft of the first motor 6 extends through the outer wall of the heating box 1 to the inside of the heating box 1 and is connected with the stirring One end of the shaft 4 is fixedly connected.

[0076] The invention is suitable for blown film manufacture of biodegradable materials, and the biodegradable materials can be existing polylactic acid (PLA) and polyterephthalic acid-adipate-butylene glycol ester (PBAT).

[0077] The workin...

Embodiment 2

[0079] On the basis of embodiment 1

[0080] Such as figure 2 As shown, the stirring blades 5 are installed on the periphery of the stirring shaft 4, and there are several stirring blades 5, and the surfaces of several stirring blades 5 are all provided with first through holes 7.

[0081] The working principle and beneficial effects of the above-mentioned technical solution are as follows: a number of stirring blades 5 are evenly distributed on the periphery of the stirring shaft 4, and a number of blades are arranged so that the stirring shaft 4 in the heating box 1 can stir more biodegradable materials. The first through hole 7 is arranged on the top, which can reduce the resistance when the stirring shaft 4 rotates, speed up the stirring speed, shorten the time for uniform mixing, and save the power of the first motor 6 .

[0082] Preferably, a first one-way valve is set in the inlet 2, and a second one-way valve is set in the outlet 3.

[0083] The working principle an...

Embodiment 3

[0085] On the basis of embodiment 1 or 2

[0086] Such as figure 1As shown, an extrusion box 8 is also included, and the extrusion box 8 is communicated with the feed port 2 through a first connecting pipe 9, and a feed box 10 is arranged on the upper end of the extrusion box 8, and the feed box 8 The lower end of 10 communicates with the upper end of the extrusion box 8; an extrusion screw is arranged inside the extrusion box 8, and the right end of the extrusion screw extends to the outside of the extrusion box 8 and is fixedly connected with the output end of the second motor 11. Others, the principle of film blowing can refer to 201420463675.5, and will not be repeated here.

[0087] The working principle and beneficial effects of the above technical solution are: the biodegradable material enters the extrusion box 8 from the feed box 10, and then is extruded into the heating box 1 from the extrusion box 8, so that the filtration and screening of the biodegradable materia...

Abstract

The invention discloses a film blowing equipment suitable for biodegradable materials. The inside of the box is also provided with a stirring shaft, the stirring shaft is provided with stirring blades, and the outside of the heating box is provided with a first motor, and the output shaft of the first motor extends through the outer wall of the heating box to the inside of the heating box and It is fixedly connected with one end of the stirring shaft. The purpose of the present invention is to provide a film blowing equipment suitable for biodegradable materials. By setting a heating box, a stirring shaft and a stirring blade are arranged in the heating box. When the heating box is heated, the first motor drives the stirring shaft to rotate, and the stirring blade Stir the biodegradable material in the heating box to make it evenly mixed, so as to ensure that the biodegradable material is fully heated and completely melted, and the quality of the blown film is improved.

Description

technical field [0001] The invention relates to the technical field of film blowing equipment, in particular to a film blowing equipment suitable for biodegradable materials. Background technique [0002] The film blowing machine heats and melts plastic particles and blows them into films. There are many kinds of film blowing machines, such as PE, POF, PVC and so on. The film blowing machine blows out new materials with brand-new particles, the color is uniform, clean, and the bag is stretched well. The existing film blowing machine is mainly composed of extruder, machine head, film blowing die, cooling device, bubble stabilizer, herringbone plate, traction roller, coiling device, etc. The film blowing machine produces films suitable for various A high-grade film packaging. The working principle of the film blowing machine is to add dry polyethylene particles into the lower hopper, and the particles enter the screw from the hopper by the weight of the particles themselves...
