[0002] Stretch film, also known as wrapping film, is a plastic film with excellent extensibility and self-adhesiveness. It is used to wrap items to provide stable fixation and protection. During use, it can be stretched and tightly wrapped around the goods or pallets to form a tight, continuous and transparent protective layer, thereby preventing the goods from loosening or being damaged due to movement, collision, etc. during transportation and storage.

[0003] After the stretch film is produced, it needs to be rolled up so that it can be wound into a roll in an orderly and tight manner, which will facilitate the subsequent storage, transportation and use of the stretch film and ensure that the stretch film can maintain good performance and use effect.

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , which is the first embodiment of the utility model, provides a deviation correction device for stretch film winding, including a base plate 1 and a support plate 101, the upper surface of the base plate 1 is fixedly connected to the support plate 101, and the outer surface of the support plate 101 is provided with a deviation correction component 2.

[0034] Specifically, the correction component 2 includes an installation box 201 arranged on the outer surface of the support plate 101, the interior of the installation box 201 is fixedly connected to a drive motor 202, the output shaft end of the drive motor 202 is fixedly connected to a gear 203, the interior of the installation box 201 is slidably connected to two racks 204, the two racks 204 are meshed with the gear 203, the sides of the two racks 204 are fixedly connected to connecting blocks 205, and the outer surfaces of the two connecting blocks 205 are provided with two second rotating rollers 206.

[0035] Furthermore, when the control system receives the deviation signal, it will immediately start the drive motor 202. When the drive motor 202 drives the gear 203 to rotate, because the two racks 204 are meshed with the gear 203, further when the gear 203 rotates, it will drive the two racks 204 to move in a direction close to or away from each other. When the racks 204 move, they will drive the two connecting blocks 205 to move synchronously, and further drive the second rotating roller 206 to move, so as to adjust the horizontal position of the stretch film. When the film deviates, the different speeds or positions of the second rotating roller 206 are adjusted to make the film return to the right position, thereby avoiding the uneven surface of the film roll caused by the deviation of the stretch film, thereby ensuring that the stretch film can fit tightly and evenly to the surface of the packaged object during the later packaging process.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The upper surface of the base plate 1 is fixedly connected with a support plate 101 , and the outer surface of the support plate 101 is provided with a stretching component 3 .

[0038] Specifically, the stretching component 3 includes a groove 301 opened inside the support plate 101, and an electric push rod 302 is fixedly connected inside the groove 301. The output shaft end of the electric push rod 302 is fixedly connected to the lower surface of the installation box 201, and an adjustment rod 305 is arranged between the two installation boxes 201. The correction component 2 includes an installation box 201 arranged on the outer surface of the support plate 101, and two sliding rails 303 are opened inside the support plate 101. The sliding rails 303 are slidably connected inside the sliding blocks 304, and the sliding blocks 304 are fixedly connected to the outer surface of the installation box 201.

[0039] Furthermore, by starting the electric push rod 302, the installation box 201 is driven to move up and down. When the installation box 201 moves, the sliding block 304 is driven to slide in the slide rail 303, so as to support and limit the installation box 201. When the installation box 201 moves, the second rotating roller 206 and the adjusting rod 305 are driven to move, so that the adjusting rod 305 and the second rotating roller 206 drive the stretch film to adjust the tension in the vertical direction, so as to control the tension of the stretch film during the winding process, so that the tension of the stretch film is appropriate, thereby ensuring the smooth winding process.

[0040] Working principle: When in use, the bottom plate 1 is installed at the designated position through the threaded holes inside the bottom plate 1 with the help of fixing bolts and nuts. At this time, the operator passes the stretch film through the two sets of first rotating rollers 102 and the second rotating roller 206, and fixes the end of the stretch film on the winding rod above the adjusting rod 305. The stretch film can be fixed by the two sets of first rotating rollers 102. Then the photoelectric sensor 208 installed on the surface of the second rotating roller 206 monitors the position of the stretch film in real time. Once the film is detected to be offset, the photoelectric sensor 208 will immediately transmit the offset signal to the control system. When the control system receives the offset signal, it will immediately start the drive motor 202. When the drive motor 202 drives the gear 203 to rotate, because the two racks 204 are meshed with the gear 203, When the gear 203 rotates, the two racks 204 are driven to move toward or away from each other. When the racks 204 move, the two connecting blocks 205 are driven to move synchronously. When the connecting blocks 205 move, they slide on the surface of the slide bar 207 to support the connecting blocks 205, and further drive the second rotating roller 206 to move, so that the position of the stretch film in the horizontal direction can be adjusted. When the film deviates, the different speeds or positions of the second rotating roller 206 are adjusted to make the film return to the right position, so as to avoid the uneven surface of the film coil caused by the deviation of the stretch film, thereby ensuring that the stretch film can fit tightly and evenly on the surface of the packaged object in the later packaging process, so as to improve the sealing and protective performance of the packaging.

[0041] When in use, the electric push rod 302 is started to drive the installation box 201 to move up and down. Further, when the installation box 201 moves, the sliding block 304 is driven to slide in the slide rail 303, so as to support and limit the installation box 201. When the installation box 201 moves, the second rotating roller 206 and the adjusting rod 305 are driven to move, so that the adjusting rod 305 and the second rotating roller 206 drive the stretch film to adjust the tension in the vertical direction, so as to control the tension of the stretch film during the winding process, so that the tension of the stretch film is appropriate, thereby ensuring the smooth winding process, and effectively avoiding problems such as film breakage, looseness or loose packaging due to excessive or insufficient tension.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
