Description

Technical Field

[0001] The utility model relates to the technical field of steel-plastic composite belts, in particular to a tear-resistant steel-plastic composite belt. Background Art

[0002] The steel-plastic composite belt is composed of a steel belt with ethylene-acrylic acid copolymer (EAA) laminated on one or both sides. The steel-plastic composite belt in the prior art is very easy to tear when resisting external high-strength tensile force due to its own structural defects, which greatly reduces the use effect of the composite belt. Some steel-plastic composite belts will add transverse reinforcement to the steel belt to improve the tensile strength of the steel-plastic composite belt. However, when the bending degree of the steel-plastic composite belt is too large, it is easy to cause plastic deformation of the transverse reinforcement, affecting the normal use of the steel-plastic composite belt.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tear-resistant steel-plastic composite belt, comprising a steel belt and a high-molecular polyethylene composite layer wrapped outside the steel belt, wherein three steel belts are provided and are arranged at equal intervals inside the steel belt, with intervals between adjacent steel belts, a slot is provided on the side of the steel belt, an elastic steel sheet is fixedly installed on the inner wall of the slot, the elastic steel sheet simultaneously connects two steel belts on both sides, grooves are provided on the upper and lower surfaces of the steel belt, a protrusion is clamped on the inner wall of the groove, and the protrusion is hot-melt pressed into one body with the high-molecular polyethylene composite layer.

[0005] Furthermore, there are a plurality of grooves which are evenly spaced on the upper and lower surfaces of the steel belt, and the protrusions are made of thermoplastic polyester elastomer, and the same protrusion is simultaneously inserted into the grooves on the three steel belts.

[0006] Furthermore, a second filler is integrally formed on the inner side of the high molecular polyethylene composite layer, and the second filler is filled in the groove on the edge steel belt.

[0007] Furthermore, a filler 1 is filled between the elastic steel sheet and the high molecular polyethylene composite layer. The filler 1 is made of elastic colloid, and the filler 1 is fixedly connected to the elastic steel sheet through the colloid.

[0008] Furthermore, the steel strip comprises a steel substrate, the upper and lower surfaces of the steel substrate are both provided with a chrome-plated layer, and the surface of the chrome-plated layer on a side away from the steel substrate is provided with a zinc-plated layer.

[0009] Furthermore, the surfaces of the elastic steel sheets are chrome-plated and zinc-plated, and the elastic steel sheets are fixedly connected to the steel belt by hot pressing.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Replace a single wider steel belt with three narrower steel belts to improve the bending resistance of the steel-plastic composite belt. By opening grooves on the steel belt and inserting the protrusions into the grooves, the tensile performance of the steel-plastic composite belt is improved. Connecting adjacent steel belts with elastic steel sheets with good elasticity can ensure the bending performance of the entire steel-plastic composite belt and the tensile performance of the steel-plastic composite belt in all directions.

[0012] 2. The protrusions made of thermoplastic polyester elastomer can be wound and bent together when the steel-plastic composite belt is wound and bent. The same protrusion is simultaneously inserted into the grooves on the three steel belts to connect the three steel belts, thereby improving the tensile strength of the steel-plastic composite belt in the lateral direction.

[0020] There are multiple grooves 5, which are evenly spaced on the upper and lower surfaces of the steel belt 1. The protrusions 6 are made of thermoplastic polyester elastomer, so that when the steel-plastic composite belt is wound and bent, the protrusions 6 can be wound and bent together. The same protrusion 6 is simultaneously inserted into the grooves 5 on the three steel belts 1, which is used to connect the three steel belts 1, thereby improving the tensile performance of the steel-plastic composite belt in the transverse direction.

[0021] The inner side of the polymer polyethylene composite layer 2 is integrally formed with a filler 2 8, which is filled in the card slot 3 on the edge steel strip 1. Filling the empty card slot 3 can also increase the contact area between the polymer polyethylene composite layer 2 and the steel strip 1, and improve the connection strength between the steel strip 1 and the polymer polyethylene composite layer 2;

[0022] A filler 7 is filled between the elastic steel sheet 4 and the high molecular polyethylene composite layer 2. The filler 7 is made of elastic colloid. The filler 7 is fixedly connected to the elastic steel sheet 4 through the colloid to fill the gap between the high molecular polyethylene composite layer 2 and the elastic steel sheet 4. At the same time, the filler 7 made of elastic colloid can ensure that when the steel-plastic composite belt is bent, the filler 7 bends together;

[0023] The steel strip 1 includes a steel substrate 101, and a chrome-plated layer 102 is provided on the upper and lower surfaces of the steel substrate 101. A zinc-plated layer 103 is provided on the side of the chrome-plated layer 102 away from the steel substrate 101.

[0025] Working principle: When in use, a groove 5 is pressed out on the steel strip 1 by die pressing, and then a slot 3 corresponding to the elastic steel sheet 4 is opened on the side of the steel strip 1. After the three steel strips 1 are placed side by side, the elastic steel sheet 4 is inserted into the slot 3, and the steel strip 1 and the elastic steel sheet 4 are fixed by hot pressing, and then the protrusion 6 is pressed into the groove 5 by hot rolling and pressing, and then the steel strip 1 and the polymer polyethylene composite layer 2 are fixed together by hot rolling and pressing. When the polymer polyethylene composite layer 2 is hot rolled and pressed, the excess polymer polyethylene compound flows into the slot 3 to form a filler 8. After the filler 7 is filled between the polymer polyethylene composite layer 2 and the elastic steel sheet 4, the preparation of the steel-plastic composite strip is completed. When subjected to lateral tension, the elastic steel sheet 4 and the protrusion 6 have a better tensile effect.
