Embodiment Construction

[0021] Refer to attached drawings. The flat packing belt involved in the present invention is a flat packing belt made of polypropylene or polyester material for a strapping machine, and the packing belt can be bonded by hot melt during packing.

[0022] As for the flat packing tape suitable for the desktop strapping machine, its width is 4.5±0.5mm, and the thickness is 0.38±0.05mm. This embodiment takes this packing tape as an example for detailed description. However, the technical solution of the present invention can also be applied to flat packing tapes of other sizes.

[0023] The flat packing belt is provided with a front side 1 and a back side 2, the front side 1 and the back side 2 are made with the same oblique embossing, the oblique embossing on the front is marked 11, and the oblique embossing on the reverse side is marked 21. The diagonal ridges on each side are parallel ridges.

[0024] As shown in the figure, the oblique rib 11 observed from the front orthogra...

Abstract

The invention aims to provide a flat packing belt which is provided with a front surface and a back surface, the front surface and the back surface are provided with the same inclined raised grains, so that the inclined direction and the inclined angle of the inclined raised grains observed from the front surface orthographic projection and the inclined raised grains observed from the back surface orthographic projection of the flat packing belt are the same as the distance between the adjacent inclined raised grains. According to the invention, through the reverse and same design of the inclined grains of the front friction grains and the reverse friction grains of the packing belt, not only is the friction effect ensured, but also the belt conveying effect and the production quality are ensured during manufacturing, the rolling operation has small influence on the strength of the belt and the tensile strength of the belt is ensured, or under the condition of ensuring the same tensile strength, the gram weight can be reduced, and the production cost is reduced. Materials are saved and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a packing belt; in particular, it relates to a flat packing belt made of polypropylene or polyester material for a strapping machine. The usual size of the packing belt is 4-19 mm in width and 0.35-1 mm in thickness. Background technique [0002] In order to increase the friction force of the flat strapping belt made of polypropylene or polyester material for the strapping machine, friction patterns are made on the front and back sides through a rolling process. Since the rolling operation is continuous feeding and continuous rolling, in order to ensure the balance of the force on the strap and the strap does not deviate, the common friction pattern is grid pattern on both sides. The gaps between the hot-pressing rollers with negative grid patterns are made on the surface, and the front and back surfaces are hot-pressed to form grid relief. Although this kind of belt has a good friction effect, the strength of the packing belt...
