Description

Technical Field

[0001] The invention relates to the technical field of film recovery equipment, and in particular to an automatic recovery machine for cigarette packaging films. Background Art

[0002] At present, in the paper box packaging and unpacking schemes of cigarette flakes in various tobacco factories, plastic bag packaging is widely used. The outer layer of the pressed cigarette flakes in the paper box packaging is covered with plastic bags. During the unpacking process, a special mechanism is used to split the sealed packaging bag in the middle, and the robot grabs the packaging bag and places it in the material box. Because the packaging bag is relatively light and occupies a large space, the operators need to frequently handle the plastic bags in the material box, resulting in high work intensity, which is not conducive to the development of automation and intelligent work, affects the work efficiency generated by automation, and is prone to safety accidents. The existing technology for shaping and preventing loose materials from rolling mostly adopts the hot melt welding mode, and also adopts the centralized compression mode to control its volume after recycling and increase the recycling volume.

[0003] There are two methods of plastic bag processing that are currently being studied in the market. One is batch compression, that is, after a batch of packaging bags are accumulated in a material box, their volume is compressed using pressure, thereby achieving a longer processing time; another is roller crushing, which tears large plastic bags into small pieces, and then collects them in the material box; another is hot melting, which collects the packaging bags, uses the principle of heating to heat-melt the plastic bags into blocks, and then collects them in the material box.

[0004] However, the above-mentioned method of collecting the packaging bags with a rolling cutter and then tearing them will generate dust and debris during the tearing process, which will float in the workspace and cause harm to the health of the workers; the above-mentioned method of using hot melting will also generate odor, which is not conducive to daily continuous production. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an automatic recycling machine for cigarette packaging film that does not generate a large amount of debris, dust and harmful smoke, aiming to alleviate the above problems at least to a certain extent.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

The two extrusion frames 107 can be moved, and the two extrusion frames 107 are displaced to the middle position of the film and contact the extruded film to press the rolled film from the middle of the two film rolling rollers 105. After the film is pressed, the compressed film can be punctured and fixed by a locking component.

After the second gear 201 is engaged with the first gear 200, the second gear 201 can rotate synchronously, thereby achieving the purpose of allowing the two film rollers 105 to rotate about the center of the first gear 200 to wind the film. The wound film can be in the shape of a circular runway, which is convenient for the subsequent compression and unloading of the film after compression.

[0050] As a further solution of the present invention, the negative pressure component includes a positioning cylinder 203 connected to the sliding frame 101, the first gear 200 is rotatably connected to the positioning cylinder 203, an air suction cavity 204 is opened in the first gear 200, the positioning cylinder 203 is communicated with the air suction cavity 204, the film rolling roller 105 extends into the air suction cavity 204 and is communicated with the air suction cavity 204, an air suction pump 205 is provided in the sliding frame 101, and an air suction pipe 206 is connected between the air suction pump 205 and the positioning cylinder 203;

When used, the vacuum pump 205 can be started, and the air inlet of the vacuum pump 205 can draw air from the suction chamber 204 through the suction pipe 206, thereby achieving the purpose of extracting air from the film roller 105.

[0052] As a further solution of the present invention, the fixing frame 102 is provided with a first support plate 300 and a second support plate 301, and the two extrusion frames 107 are respectively provided on both sides of the first support plate 300 and the second support plate 301 close to each other, and the first support plate 300 and the second support plate 301 are respectively provided with a first electric push rod 302, and the telescopic shaft of the first electric push rod 302 is connected to the extrusion frame 107;

[0053] By setting the first support plate 300 and the second support plate 301, the first support plate 300 and the second support plate 301 can support the position of the first electric push rod 302, and raise the position of the first electric push rod 302, so that the extrusion frame 107 can correspond to the middle position of the film. When in use, the operator can start the first electric push rod 302, and the movement of the telescopic shaft of the first electric push rod 302 can make the extrusion frame 107 move toward the film, thereby achieving the purpose of compressing the film.

[0055] By setting the locking plate 400, when in use, the first electric push rod 302 is first used to move the position of the extrusion frame 107, so that the extrusion frame 107 can compress the film, providing the prerequisite for the pushpin 402 to pierce. After compressing the film, the operator can move the positions of the two locking plates 400 to make the two locking plates 400 move closer to each other. The pushpin 402 on one of the locking plates 400 pierces the compressed film and rivets it with the riveting plate 404 on the other locking plate 400, so that the compressed film can be fixed, thereby reducing the volume of the film after winding, which is convenient for subsequent collection.

The rotation of the third gear 603 can cooperate with the rack 600 to achieve the purpose of allowing the sliding frame 101 to move linearly on the top of the bracket 100.
