Description

Technical Field

[0001] The utility model relates to the technical field of packaging film production, in particular to a polyvinyl chloride packaging film winding device with a replaceable reel. Background Art

[0002] Plastic packaging film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] Publication No. CN218579239U discloses a winding device for producing plastic packaging film. By starting an air pump, the air inside the dust filter box is extracted through an air inlet pipe, so that a negative pressure is formed inside the dust filter box. Then, the air inside the dust suction pipe can be sucked through the air suction pipe. The dust suction pipe absorbs the air inside the dust groove through the through hole. The surface of the dust removal roller is in close contact with the surface of the conveyed plastic packaging film, so that the two dust suction grooves on the dust removal roller contact the surface of the plastic packaging film in turn during the rotation, and absorb the dust attached to the surface, thereby ensuring that the surface of the plastic packaging film before the winding process does not adhere to dust, preventing the plastic film from being worn, and improving the processing quality of the plastic film; the dust-containing air is transported to the interior of the dust filter box through the air suction pipe, and after being filtered twice by the dust filter plates on the top of the two mounting frames, the clean air is discharged through the air outlet pipe, thereby improving the quality of the plastic packaging film production environment. However, this patent still has the following problems during actual use:

[0004] The plastic packaging film that is wound up is not easy to be damaged, and the film that is being ...

[0005] A polyvinyl chloride packaging film winding device with a replaceable reel is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a polyvinyl chloride packaging film winding device with a replaceable reel, so as to solve the problem proposed in the above background technology that the gas inside the dust filter box is currently extracted through the air intake pipe, so that a negative pressure is formed inside the dust filter box, and then the gas inside the dust suction pipe can be sucked through the exhaust pipe. The dust suction pipe absorbs the gas inside the dust groove through the through hole, and the surface of the dust removal roller is in close contact with the surface of the conveyed plastic packaging film, ensuring that dust will not adhere to the surface of the plastic packaging film before the winding process, thereby preventing the wear of the plastic film. However, after the packaging film is wound, it is inconvenient to replace the reel, thereby reducing the working efficiency of the equipment.

The winding mechanism not only enables the rotation of the roller to wind the PVC packaging film body, but also facilitates the replacement of the roller, improving the winding efficiency of the equipment. The roller is limited by the latch, which allows the roller and the worm gear to rotate together. The worm is driven by the drive motor to rotate, and the meshing action between the worm and the worm gear drives the worm gear and the roller to rotate, thereby winding the PVC packaging film body. The latch is limited by the stopper to prevent the latch from falling off during rotation, thereby improving the stability of the device.

When the second support plate is in a horizontal state, the limitation of the second support plate on the roller can be released, which facilitates the roller to be pulled out from the horizontal direction. By utilizing the engagement relationship between the pull rod and the Z-shaped block, one side of the hinged plate can be fixed to the base, and the second support plate can be placed vertically to limit the roller, thereby improving the stability of the roller wrapped around the polyvinyl chloride packaging film body.

[0033] A worm gear 106 is meshedly connected to one side of the worm 105. A roller 107 is attached to the center of the worm gear 106. One end of the roller 107 passes through the first support plate 102 and is attached to a polyvinyl chloride packaging film body 108. Limiting plates are provided on both sides of the roller 107 near the polyvinyl chloride packaging film body 108 to prevent the polyvinyl chloride packaging film body 108 from deflecting when being wound.

A threaded rod 112 is threadedly connected to the center of one end of the limit block 111. One end of the threaded rod 112 is rotatably connected to a connecting block 113. The threaded action between the threaded rod 112 and the limit block 111 drives the connecting block 113 to move toward the threaded rod 112, while causing the two blocking rods 114 to rotate around the limit block 111.

[0035] The upper and lower ends of the connecting block 113 are symmetrically connected to the blocking rods 114 for rotation. One end of the outer center position of the two blocking rods 114 is rotatably connected to the limit block 111. The end of the blocking rod 114 away from the connecting block 113 passes through the limit block 111 and is engaged with the latch 110.

[0039] Working principle: Before using this kind of PVC packaging film winding device with a replacement roll, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 7 As shown, first, the drive motor 104 is started to drive the worm 105 to rotate. The meshing action between the worm 105 and the worm wheel 106 drives the worm wheel 106 and the roller 107 to rotate, so that the polyvinyl chloride packaging film body 108 can be wound. After the winding is completed, the drive motor 104 is turned off, and the threaded rod 112 is rotated. The threaded action between the threaded rod 112 and the limit block 111 drives the connecting block 113 to move toward the threaded rod 112, and at the same time, the two stop rods 114 rotate around the limit block 111, thereby releasing the stop rod 114 from limiting the position of the latch 110, and the latch 110 can be removed from the fixing block 109, thereby releasing the stop pin 110 from limiting the position of the roller 107;

[0040] Secondly, push the push rod 211 downward to drive the connecting rod 209 to move toward the Z-shaped block 205, so that the Z-shaped block 205 can rotate around the limiting column 207, and the limiting of the pull rod 203 by the Z-shaped block 205 can be released, so that the pull rod 203 can be pulled out from the hinge plate 201, and the limiting of the pull rod 203 on the hinge plate 201 can be released. Then, the second support plate 202 is placed horizontally to release the limiting of the roller reel 107, and finally, the roller reel 107 is taken out from the horizontal direction to realize the disassembly of the roller reel 107.
