Description

Technical Field

[0001] The utility model relates to the field of cotton picker packing films, in particular to a joint of a cotton picker packing film. Background Art

[0002] A cotton picker is an agricultural machine for collecting cotton, which improves the picking efficiency and reduces the labor cost. The cotton picker packing film is generally made of polyethylene material, which is a widely used packing film material with excellent corrosion resistance, heat resistance and waterproof performance.

[0003] For the convenience of the cotton picker to pack cotton, double-sided tape is used for pasting and connecting at the joint of the packing film. When the cotton picker pulls the packing film, the packing film will peel off the double-sided tape, which is convenient for the packing film to continuously pack cotton. At present, although the packing film joints on the market adopt double-sided tape for connection, none of them use PET film as the connection material. The joints are too soft, and problems such as poor film feeding and film blocking are likely to occur, reducing the finished product utilization rate of the packing film.

[0004] Therefore, a joint of a cotton picker packing film is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a joint of a cotton picker packing film, aiming to improve the problem that the existing packing film joints on the market are too soft and prone to poor film feeding and film blocking.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A joint of a cotton picker packing film, including a PET film sheet, a release layer is fixedly connected to the surface of the PET film sheet, a first connecting adhesive layer is pasted on the top of the release layer, a second connecting adhesive layer is pasted on the right side of the top of the PET film sheet, packing film base layers are arranged on both sides of the top of the PET film sheet, and the tops of the first connecting adhesive layer and the second connecting adhesive layer are both pasted on the surface of the packing film base layer;

[0008] As a further description of the above technical solution:

[0009] The release layer is a silicone oil layer;

[0010] As a further description of the above technical solution:

[0011] Both the first connecting adhesive layer and the second connecting adhesive layer are double-sided tapes;

[0012] As a further description of the above technical solution:

[0013] The side of the PET film sheet away from the release layer is a non-silicone oil surface.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by the combined use of a PET film, a release layer, a first connecting adhesive layer, a second connecting adhesive layer and a packing film base layer, the problems of poor film feeding and film jamming are effectively solved, and the advantages of convenient separation and film feeding are achieved. As a connecting material, PET has a certain hardness and can perfectly adhere to the double-sided adhesive, without the problem that the connecting material cannot completely cover the surface of the double-sided adhesive due to the softness and distortion of the connecting material. At the same time, unnecessary waste of joints in the production process is reduced.

[0016] 2. In the utility model, by setting the release layer as a silicone oil layer for combined use, it is convenient for the first connecting adhesive layer to separate from the PET film, preventing the phenomenon that the first connecting adhesive layer cannot quickly separate from the PET film. Description of the Drawings

[0017] Figure 1 is a three-dimensional schematic diagram of a joint of a cotton picker packing film proposed by the utility model;

[0018] Figure 2 is an exploded structure diagram of a joint of a cotton picker packing film proposed by the utility model;

[0019] Figure 3 is a structural schematic diagram after the PET film of a joint of a cotton picker packing film proposed by the utility model is separated;

[0020] Figure 4 is a structural schematic diagram of a PET film of a joint of a cotton picker packing film proposed by the utility model.

[0021] Legend Explanation:

[0022] 1. PET film; 2. Release layer; 3. First connecting adhesive layer; 4. Second connecting adhesive layer; 5. Packing film base layer. Specific Embodiments

[0023] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a joint of a cotton picker packing film, including a PET film 1, a release layer 2 is fixedly connected to the surface of the PET film 1, a first connecting adhesive layer 3 is pasted on the top of the release layer 2, and the first connecting adhesive layer 3 can be quickly separated from the release layer 2. A second connecting adhesive layer 4 is pasted on the right side of the top of the PET film 1. Both the first connecting adhesive layer 3 and the second connecting adhesive layer 4 are double-sided adhesives. Packing film base layers 5 are arranged on both sides of the top of the PET film 1. The tops of the first connecting adhesive layer 3 and the second connecting adhesive layer 4 are both pasted on the surface of the packing film base layer 5.

[0025] Referring to Figures 2 - 4 , the release layer 2 is a silicone oil layer. By setting the release layer 2 as a silicone oil layer for combined use, it is convenient for the first connecting adhesive layer 3 to detach from the PET film 1, preventing the phenomenon that the first connecting adhesive layer 3 cannot be quickly detached from the PET film 1. At the same time, it can protect the surface of the PET film 1. The side of the PET film 1 away from the release layer 2 is a non-silicone oil surface.

[0026] Working principle: The user first puts the packing film base layer 5 into the cotton picker. The cotton picker pulls the packing film base layer 5 on the top of the second connecting adhesive layer 4. The packing film base layer 5 pulls the PET film 1 through the second connecting adhesive layer 4, so that the PET film 1 detaches from the first connecting adhesive layer 3 through the release layer 2, facilitating the packing of cotton by the packing film base layer 5, achieving the advantage of convenient separation and film feeding.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
