Description

Technical Field

[0001] This utility model relates to the field of film packaging equipment, and in particular to an environmentally friendly PE stretch film packaging device. Background Technology

[0002] Environmentally friendly PE stretch film (also known as wrapping film, protective film, or wrap film) is a self-adhesive packaging material made from linear low-density polyethylene (LLDPE) as the main raw material, supplemented with tackifiers, anti-aging agents and other additives, through a casting extrusion process.

[0003] In the field of automated packaging, large manufacturing enterprises generally use fully automatic wrapping machines to achieve efficient and stable packaging results. However, for small and medium-sized enterprises, the purchase and maintenance costs of fully automatic equipment constitute a significant economic burden, so they still use manual packaging methods: operators hold the film roll and wrap it layer by layer by rotating it around the goods. During this process, it is necessary to periodically pause the film output, manually stretch the film material to the appropriate tension, and then continue wrapping. Repeatedly controlling the output and stretching is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an environmentally friendly PE stretch film packaging device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An environmentally friendly PE stretch film packaging device includes: a support frame, on which a movable disc is rotatably mounted; the bottom of the movable disc passes through the support frame via a rotating shaft; a circular block with a rough outer surface mounted on the bottom of the rotating shaft; a pressing mechanism mounted on the support frame for cooperating with the movable disc to press and fix the film roll; and a first sleeve block mounted on the bottom of the support frame, on which a first screw is provided; a rubber block is bonded and fixed to one side of the first screw, and the force of the rubber block pressing the circular block is adjusted by rotating the first screw, thereby adjusting the resistance encountered by the movable disc when rotating, and using the resistance to stretch the film material, eliminating the need to periodically pause film output and then manually stretch the film material.

[0006] Preferably, the extrusion mechanism includes a second screw mounted on the top of the bracket; it also includes a fixing block mounted on the bottom of the second screw, on which a second sleeve block is fitted; and an extrusion disc that rotates around the fixing block via the second sleeve block is mounted on the bottom of the second sleeve block.

[0007] Preferably, a rotating block for rotating the second screw is installed on the second screw.

[0008] Preferably, the vertical cross-section of the fixing block is convex to prevent the second set of blocks from detaching from the fixing block.

[0009] Preferably, the center points of the extrusion disc and the movable disc are located on the same vertical line to cooperate in fixing the film roll.

[0010] Preferably, it also includes a correction mechanism mounted on the bracket for correcting the flatness of the pulled-out membrane.

[0011] Preferably, the straightening mechanism includes rotatably mounted movable rollers, at least two of which are provided, through which the film passes. The movable rollers ensure the flatness of the pulled-out film.

[0012] Preferably, it also includes a support block mounted on the bracket for supporting the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model include: 1. The rotation of the first screw adjusts the pressure of the rubber block on the round block, thereby adjusting the resistance encountered when the movable disc rotates. The resistance stretches the film material. After the person holds the support, the film roll is pulled out and wrapped around the outside of the item to be packaged. The film material is directly wrapped by resistance stretching, without the need for manual stretching. This avoids the periodic pause of film output, reduces labor intensity, and improves the wrapping and packaging efficiency.

[0014] 2. Improve the flatness of the pulled film by using movable rollers to prevent the pulled films from adhering and sticking together, thus reducing the film coverage area. Attached Figure Description

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.

[0018] An environmentally friendly PE stretch film packaging device includes: a support 1, which is U-shaped, with a handle 2 for picking up the support 1 bolted to one side, and a soft pad glued to the handle 2. A movable disc 5 is rotatably mounted at the bottom of the support 1; the movable disc 5 can be square, polygonal, etc., preferably circular. A rotating shaft 14, welded to the bottom of the movable disc 5, passes through the support 1. The device also includes a circular block 11 with a rough outer surface welded to the bottom of the rotating shaft 14, and a first sleeve block 10 welded to the bottom of the support 1, which fits over the circular block 11. A first screw 12 is threaded through one side of the first sleeve block 10, and a rotating block for rotating the first screw 12 is welded to one side of the first screw 12. A rubber block 13 is bonded and fixed to one side of the first screw 12. The force of the rubber block 13 pressing the round block 11 is adjusted by rotating the first screw 12, thereby adjusting the resistance encountered when the movable disk 5 rotates. The resistance stretches the film material. Thus, when the support 1 is held manually, the film on the roll is pulled out and wrapped around the outside of the item to be packaged. The film material is directly wrapped, and the resistance stretches the film material without manual stretching. This avoids the need for periodic pauses in film dispensing and manual stretching of the film material to the appropriate tension before continuing the wrapping. The wrapping operation can be continued continuously. It also includes a pressing mechanism installed at the top of the support 1 to cooperate with the movable disk 5 to press and fix the film roll.

[0019] Specifically, the extrusion mechanism includes a second screw 6 fixed to the top of the support 1 by threaded insertion, wherein a rotating block for rotating the second screw 6 is welded to the top of the second screw 6; it also includes a fixing block 7 welded to the bottom of the second screw 6, wherein the vertical cross-section of the fixing block 7 is convex, and a second sleeve block 8 is movably sleeved on the outside of the fixing block 7; an extrusion disc 9, which rotates around the fixing block 7 via the second sleeve block 8, is welded to the bottom of the second sleeve block 8, wherein the extrusion disc 9 is a circular disc. The center points of the extrusion disc 9 and the movable disc 5 are located on the same vertical line.

[0020] In this embodiment, a correction mechanism installed inside the bracket 1 is also included to correct the flatness of the pulled-out membrane.

[0021] In this embodiment, the correction mechanism includes a rotatably mounted movable roller 3, wherein at least two movable rollers 3 are provided, and the film passes through the gap between the movable rollers 3, and the movable rollers 3 ensure the flatness of the pulled film.

[0022] In this embodiment, a support block 4 is also welded and fixed to the side of the bracket 1 to support the bracket 1. When idle, if the movable disk 5 still has a film roll fixed, it is supported by the support block 4 to prevent the film from being contaminated by direct contact with the placement point.

[0023] Working principle: When in use, first place the film roll between the extrusion plate 9 and the movable plate 5, and place it on the movable plate 5. Then, rotate the second screw 6 so that the second screw 6 drives the extrusion plate 9 to move downward until the extrusion plate 9 is tightly attached to the top of the film roll. At this time, the film roll is fixed. Since the second set of blocks 8 rotates around the fixed block 7, the movable disk 5 rotates on the bracket 1 via the rotating shaft 14. Thus, the membrane roll can still rotate after being fixed, making it convenient to pull out the membrane. Pull the film out and pass it through the gap between the movable rollers 3. The movable rollers 3 improve the flatness of the pulled film. During the film pulling process, the film roll rotates and then the film is wrapped around the outside of the item to be packaged. Rotating the first screw 12 moves the rubber block 13, adjusting the distance between the rubber block 13 and the round block 11 to adjust the resistance when the round block 11 rotates. This resistance is used to tension the membrane material, eliminating the need for manual stopping of the membrane release and stretching, thus simplifying the operation.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
