Abstract
Description
Technical Field
[0001] The utility model relates to the field of fresh-keeping bag production, in particular to a self-adaptive fresh-keeping bag production tension regulating device. Background Art
[0002] In the production process of fresh-keeping bags, the raw materials need to be put into the extruder for processing. The extruder will heat the raw materials and extrude them into a film of a certain thickness. In order to ensure that the film has consistent size and performance after production, the tension of the film needs to be adjusted during the production process. Existing devices generally use auxiliary tools to press the film during transportation so that the film can remain in a tensioned state, which is convenient for subsequent processing operations and treatment. However, the existing devices lack certain adjustment flexibility during use. The tension degree of the film is different in different film transportation states. The downward pressure adjustment at the same position is likely to cause the film to break or be insufficiently tensioned, and it is difficult to ensure the fit of the film, thereby weakening the tension adjustment effect and reducing the final fresh-keeping bag production effect.
[0003] Therefore, a self-adaptive tension regulating device for fresh-keeping bag production is now developed in response to the above problems. Utility Model Content

[0006] As an improvement of the above scheme, it also includes a fixing member, the left and right sides of the mounting frame are connected to the fixing member, the fixing member is slidably connected to a friction member, and a spring is connected between the friction member and the adjacent fixing member.
[0007] As an improvement of the above solution, two mounting holes are provided on the mounting frame.
[0008] As an improvement of the above solution, both left and right ends of the lifting rod are provided with limit blocks.
[0009] As an improvement of the above solution, the inner side of the air guide frame is a slope structure.

[0011] By adopting the above technical solution, the utility model has the following advantages:
[0012] The utility model can quickly adjust the position of the lower pressure roller according to the conveying state of the film, and guide the airflow through the air guide frame, so that the film can always fit with the lower pressure roller, maintain the compaction effect on the film, and keep the film in a tensioned state during the production process, thereby improving the production effect of the fresh-keeping bag.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] An adaptive tension adjustment device for fresh-keeping bag production, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, which has two mounting holes. A rotating roller 2 is rotatably arranged on the upper part of the mounting frame 1, and a winding cloth 3 is wound on the rotating roller 2. A lower pressure roller 4 for pressing and limiting the fresh-keeping bag is connected to the lower side of the winding cloth 3. Guide frames 6 are connected to the lower sides of the left and right parts of the mounting frame 1. The lower pressure roller 4 is connected to a lifting rod 5. The left and right sides of the lifting rod 5 are slidably connected to the adjacent guide frames 6. The left and right ends of the lifting rod 5 are provided with limiting blocks. An air guide frame 41 for guiding the airflow to move is connected between the lower sides of the guide frames 6, and the inner sides of the air guide frames 41 are all inclined structures.
[0019] like Figure 3 As shown, it also includes a fixing part 7, and the fixing parts 7 are connected to the left and right sides of the mounting frame 1. The fixing parts 7 are slidably connected to friction parts 8 for pressing and limiting the rotating roller 2. The lower side of the friction parts 8 is an arc surface structure, and springs 9 are connected between the friction parts 8 and the adjacent fixing parts 7.
[0020] It should be noted that when producing fresh-keeping bags, in order to improve the production effect, it is necessary to adjust the tension of the film. First, the mounting frame 1 is installed through the mounting hole. After the installation is completed, the friction member 8 is pulled upward, so that the spring 9 is compressed. At this time, the rotating roller 2 is no longer squeezed and frictioned, and can rotate freely. Then the winding cloth 3 is released, so that the lower pressure roller 4 drives the lifting rod 5 to slide downward along the guide frame 6, so that the lower pressure roller 4 can contact the film, and then the film is compressed and limited, so that the film remains in a tensioned state. The operator can adjust the height position of the lower pressure roller 4 at any time according to the state of the film to achieve the effect of adaptive adjustment. When adjusting the tension, the airflow output device can be connected to the air guide frame 41, so that the film can keep in contact with the lower pressure roller 4, improve the compression and limiting effect, ensure that the film has consistent size and performance after production, and improve the production effect of fresh-keeping bags.
