Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural harvesting crop packaging material technical field especially a winding type packing film fault sealant structure for cotton, straw feed etc. BACKGROUND

[0002] In prior art, winding packaging roll film is applied to crop harvesting material packaging field, can realize automatic packing by automatic packaging machinery, and the conventional packaging operation for packing cotton, silage feed etc.

[0003] The winding packaging roll film is generally divided into several packaging sections, and the non-adhesive area of the previous packaging section and the adhesive area of the next packaging section are connected through a separable adhesive tape.

[0004] Because the structure of the separable adhesive tape is different, the effects are also different, and some structure designs in prior art are complex, which not only increases the complexity of production process, but also increases production cost. For example, the authorized Chinese patent CN107142033B discloses an automatic packing roll film, in which the non-adhesive area of the previous packaging section and the adhesive area of the next packaging section are connected through a separable adhesive tape. SUMMARY

[0005] The winding type packing film fault sealant structure provided by the utility model has the advantages of simple structure, reduced production cost, increased material package sealing tightness, and is not easy to stick during the separation process of the packing roll film unit.

[0006] The utility model discloses a winding type packing film fault sealant structure, it is mainly including stripiness release film, two adhesive areas are arranged on the release film upper surface lengthways, namely A adhesive area, B adhesive area, A adhesive area, B adhesive area all are attached on release film, A adhesive area is pasted to the front of release film, B adhesive area is pasted to the back of release film, interval band is equipped between A adhesive area, B adhesive area, so that A adhesive area, B adhesive area interval certain distance, when A adhesive area and the attached release film part, after folding 180 degrees upwards, can be arranged in parallel with B adhesive area and the attached release film part, and A adhesive area, B adhesive area are located the same side of release film.

[0007] As preferred, the material of the release film is PET plastic.

[0008] As preferred, the adhesive area refers to double-sided adhesive with certain thickness or film-shaped double-sided adhesive.

[0009] As preferred, the width of A adhesive area is 170mm, and the width of B adhesive area is 50mm. The length of the stripiness release film is 1.8m-2.3m.

[0010] The winding type packing film fault sealant structure provided by the utility model sets two adhesive areas, namely A adhesive area and B adhesive area, on the surface of the release film, and the two adhesive areas are respectively located on the front and back surfaces of the release film. In the production process, the cutting width of the A adhesive area and the B adhesive area is determined according to the width of the film roll, and the cutting can form a separable adhesive tape for connecting the film roll units. When connecting, the A adhesive area is pasted below the end of one film roll unit, the B adhesive area is pasted below the end of the next film roll unit after being folded upward, and the disconnection line between the two film roll units is just aligned with the interval band position, so that the double-sided adhesive is quickly pasted on the two adjacent ends of the film roll units.

[0011] The winding type packing film fault sealant structure is designed as a two-section structure with one wide section and one narrow section. When the film roll units are separated, the wide section, i.e. the A adhesive section, remains on the film roll unit being packed, and the completed material package seal provides a guarantee for the tightness of the package seal. The narrow section, i.e. the B adhesive section, remains on the next film roll unit. The packing film fault sealant structure of the utility model has a simple structure, reduces the production cost, and simplifies the production process.

[0012] Compared with the prior art, the winding type packing film fault sealant structure has the advantages of simple structure, reduced production cost, tight and firm material package seal, and less adhesion during the material packaging process, and is an economical and practical winding type packing film fault sealant structure.
