Description

Technical Field

[0001] This utility model belongs to the field of cotton harvester technology, and in particular relates to a cotton harvester baling film. Background Technology

[0002] A cotton harvester is an agricultural machine used to collect cotton, improving harvesting efficiency and reducing labor costs. The packing film of cotton harvesters is generally made of polyethylene material, which is a widely used packing film material with excellent corrosion resistance, heat resistance and waterproof performance.

[0003] To facilitate cotton baling by cotton harvesters, most baling films on the market currently use PE film with serrated lines pressed into it. The cotton harvester then forcibly separates the film using its inertia. However, this process can lead to continuous separation and poor baling results after the film breaks apart. Consequently, it becomes difficult for the next baling film to automatically enter the cotton harvester's baling chamber, resulting in issues such as poor film feeding, film blockage, and film getting tangled on the film feeding roller. This reduces the utilization rate of the baling film and severely impacts the working efficiency of the cotton harvester.

[0004] In addition, the existing packaging film has the following problems: (1) it forms a straight barrel shape after packaging; (2) the packaging is not tight, a lot of cotton falls off, and even the package bursts; (3) the unit film cannot be automatically separated in the cotton harvester.

[0005] Therefore, designing a new type of cotton harvester packaging film has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The problem this invention aims to solve is to provide a cotton harvester baling film that enables automatic separation of unit films, smooth film feeding, avoids film entanglement and blockage, and reduces the risk of cotton bales bursting.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cotton harvester packaging film, comprising a plurality of unit films arranged in sequence, with adjacent unit films being detachably connected. Each unit film includes a base film, one end of which is an adhesive end and the other end is a peeling end. The surface of the adhesive end is provided with double-sided adhesive, and the peeling end is provided with a peeling film. One end of the peeling film is fixed to the peeling end, and the other end of the peeling film extends out of the peeling end and forms a peelable connection with the double-sided adhesive of the adhesive end. An adhesive coating layer is provided on the base film, and the adhesive coating layer is located on one side of the adhesive end and is adjacent to the double-sided adhesive of the adhesive end.

[0008] Furthermore, in order to better wrap the cotton, the two ends of the base film are cut to make the width of the two ends of the base film smaller than the width of the center of the base film.

[0009] Furthermore, an identification tag is provided on the back of the adhesive end. When the identification sensor at the tail of the cotton harvester detects the tag, it automatically stops feeding the film, and the two unit films automatically separate.

[0010] Furthermore, the release film includes a peelable side and a non-peelable side, with the non-peelable side facing the base film. One end of the release film is fixed to the peelable end of the base film by a fixing adhesive. The extended end of the release film is folded downward so that its peelable side faces the base film, thereby forming a peelable connection between the extended end of the release film and the double-sided adhesive of the adhesion end.

[0011] Furthermore, the release film is a PET release film.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects:

[0013] The packaging film of this utility model includes several unit films connected end to end. Adjacent unit films are connected by double-sided adhesive and PET release film. The unit films can be completely separated. Each unit film is equipped with an identification label at the end to realize automatic separation of unit films.

[0014] The cut-edge design at both ends of this utility model can better wrap the cotton, thus ensuring that the cotton bale has edges on both sides and solving the problem of poor film feeding in the next unit.

[0015] This invention connects adjacent unit films using double-sided adhesive and folded PET release film, allowing for complete disconnection between unit films without any resistance. This not only solves the problem of the next unit film rebounding when a unit film is disconnected, but also effectively solves problems such as film entanglement and blockage.

[0016] Each unit membrane of this invention has an adhesive layer at its end, which not only reduces the pressure of the double-sided adhesive at the adhesive end, but also makes the outer layer of the cotton bag more tightly wrapped, reducing the risk of the cotton bag bursting.

[0023] like Figures 1 to 3 As shown, the present invention provides a cotton harvester packaging film, comprising a plurality of unit films 1 arranged in sequence, with adjacent unit films 1 being detachably connected. Each unit film 1 includes a base film 2, one end of which is an adhesive end 3 and the other end is a peeling end 4. The surface of the adhesive end 3 is provided with double-sided adhesive 5, and the peeling end 4 is provided with a peeling film 6. One end of the peeling film 6 is fixed to the peeling end 4 by a fixing adhesive 7, and the other end of the peeling film 6 extends out of the peeling end 4 and forms a peelable connection with the double-sided adhesive 5 of the adhesive end 3.

[0024] A coating layer 8 is provided on the base film 2. The coating layer 8 is located on one side of the adhesion end 3 and is adjacent to the double-sided adhesive 5 of the adhesion end 3. It can be seen that in order to reduce the pressure of the double-sided adhesive 5 at the sealing point of the unit film 1, an intermittent coating method is adopted, and a coating layer 8 is provided at the end of each unit film 1, so that the outer layer of the cotton bag is more tightly wrapped and the risk of the cotton bag bursting is reduced.

[0025] The release film 6 includes a peelable side 9 and a non-peelable side 10. The non-peelable side 10 faces the base film 2. One end of the release film 6 is fixed to the peelable end 4 of the base film 2 by a fixing adhesive 7 (which can be double-sided adhesive). The protruding end of the release film 6 is folded downwards so that its peelable side 9 faces the base film 2, thereby forming a peelable connection between the protruding end of the release film 6 and the double-sided adhesive 5 of the adhesion end 3. This design allows for complete disconnection between unit films 1 without any resistance, solving not only the problem of the next unit film 1 rebounding when a unit film 1 is disconnected, but also effectively solving problems such as film entanglement and film blockage.

[0026] Among them, the release film 6 is a PET release film.

[0027] To better wrap the cotton, the base film 2 is trimmed at both ends so that the width at both ends of the base film 2 is smaller than the width at the center of the base film 2. In this embodiment, the trimmed lengths at both ends of the base film 2 can be 8cm each. This not only ensures that the cotton bale has about 8cm of wrapping on both sides, but also solves the problem of poor film feeding in the next unit.

[0028] An identification tag 11 is provided on the back of the adhesion end 3. After the identification sensor at the tail of the cotton harvester detects it, it automatically stops feeding the film and the two unit films 1 automatically separate.

[0029] like Figure 3 As shown, the peeling end 4 of unit membrane 1 is the packaging start end, and the adhesion end 3 is the packaging end end.

[0030] Working principle:

[0031] The packaging film of this utility model includes several unit films 1 connected end to end. Each unit film 1 has an adhesive layer 8 at the end. Adjacent unit films 1 are connected by double-sided adhesive 5 and PET release film. The unit films 1 can be completely separated. Each unit film 1 is provided with an identification label 11 at the end to realize automatic separation of unit films 1.

[0032] During packaging, the adhesive layer 8 can reduce the pressure of the double-sided tape 5 when sealing the adhesive end 3 of the unit film 1. The adhesive layer 8 on each unit film 1 adjacent to the adhesive end 3 makes the outer layer of the cotton bag more tightly wrapped, reducing the risk of the cotton bag bursting.

[0033] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
