Technical Field
The utility model belongs to the technical field of ropes, and particularly relates to a novel hard rope and a V-shaped belt.
Background
The polyester, a polymer obtained by polycondensation of polyhydric alcohol and polybasic acid, belongs to a high molecular compound, and is an engineering plastic with excellent performance and wide application. The polyester rope is widely applied to the fields of modern agriculture, packaging industry, medical and health, electronic and electric appliances, buildings and the like. At present, the existing impregnated polyester thread rope is formed by immersing the polyester thread rope in adhesive liquid, and the adhesive cannot be soaked in the prepared polyester thread rope, so that the polyester thread rope is easy to age due to internal friction heat after being repeatedly wound, and the service life of the thread rope is reduced.
Disclosure of Invention
The utility model aims to provide a novel hard rope and a V-shaped belt, and aims to solve the technical problem that the service life of the rope is shortened due to the fact that an adhesive is not arranged inside the existing impregnated polyester rope.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the novel hard rope comprises a plurality of polyester round strip monofilaments which are stranded, wherein the diameter of each polyester round strip monofilament is 0.5-2mm, and adjacent polyester round strip monofilaments are bonded and fixed through an adhesive.
Preferably, the polyester round filaments are spun by a polyester spinning machine.
Preferably, the hard thread comprises three or more polyester round filaments.
Preferably, three or more polyester round filaments are twisted into a hard rope by adopting spiral twisting.
Preferably, three or more than three polyester round monofilaments are stranded into a hard rope by a rope making machine.
Preferably, the adhesive is a polyester adhesive.
The utility model also provides a V-shaped belt, which comprises a rubber body and an inner framework thereof, wherein the framework is made of hard ropes.
The beneficial effects of adopting above-mentioned technical scheme to produce lie in: compared with the prior art, the utility model has the advantages that the polyester round strip monofilaments with the diameters of 0.5-2mm are immersed in the adhesive in advance, and then the polyester round strip monofilaments are twisted to form the hard rope, and the hard rope consists of the polyester round strip monofilaments with high density, so that the tensile strength is higher than that of the traditional rope; the adjacent polyester round filaments are bonded and fixed through the adhesive, compared with the traditional ropes, the internal adhesive force is stronger, the hard ropes are still very stable after being repeatedly wound, and the internal heat generation is reduced, so that the service life of the hard ropes is prolonged, and the service life of V-shaped belt products or other products manufactured by the hard ropes is prolonged.
Drawings
The utility model will be described in further detail with reference to the drawings and the detailed description.
Fig. 1 is a schematic structural view of a novel hard rope according to an embodiment of the present utility model;
fig. 2 is a cross-sectional view of a hard cord in accordance with one embodiment of the present utility model;
in the figure: 1-hard thread rope, 2-polyester round monofilament.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 and 2, the novel hard rope provided by the utility model is characterized in that the hard rope 1 is formed by stranding a plurality of polyester round strip monofilaments 2, the diameter of each polyester round strip monofilament 2 is 0.5-2mm, and adjacent polyester round strip monofilaments 2 are bonded and fixed through an adhesive. Wherein the hard thread 1 comprises three or more than three polyester round filaments 2. The hard cords made from high density polyester round filaments have a higher tensile strength than conventional cords.
In one embodiment of the utility model, the polyester round-bar monofilament is spun by a polyester spinning machine. Immersing the spun polyester round filaments in the polyester adhesive in advance, enabling each polyester round filament to fully contact the polyester adhesive, stranding three or more than three polyester round filaments by a rope making machine, shaping and winding the twisted yarns by high-temperature stretching, and finally forming the hard rope. In the specific manufacturing process, the stretching and shaping temperature is 220-235 ℃ and the stretching multiple is 1.02-1.05. The polyester round monofilament inside the hard rope manufactured by the method is contacted with the adhesive, compared with the traditional rope, the internal adhesive force is stronger, the hard rope is very stable after being repeatedly wound, and the internal heat generation can be reduced, so that the service life of a product manufactured by using the hard rope is prolonged.
In the concrete manufacturing process, the adhesive is a polyester adhesive. Immersing the polyester round filaments in the polyester adhesive ensures that all the polyester round filaments are saturated in the polyester adhesive. The polyester adhesive has the advantages of low viscosity, high infiltration speed, good adhesion capability to various metal and nonmetal materials, high transparency and the like.
As a preferable structure, three or more polyester round filaments are twisted into a hard rope by spiral twisting. Because the hard rope adopts few high-density polyester round monofilament strands to be stranded, the hard rope has high transverse rigidity, and can reduce the deformation of products made of the hard rope after being pulled, thereby further prolonging the service life of the hard rope and the products thereof. Meanwhile, the hard thread rope with the spiral structure is used for manufacturing V-shaped belts or other products, so that the surface area of the thread rope can be increased to achieve sufficient contact with rubber, the adhesive force is improved, and the service life of the products is prolonged.
The utility model also provides a V-shaped belt, which comprises a rubber body and an inner framework thereof, wherein the framework is selected from the hard ropes. All V-belts containing the hard ropes with the structures are within the protection scope of the utility model. The hard thread rope can be used as a framework material of a common V belt or a cut V belt, and the performance of the product can be improved.
In summary, the V-shaped belt has the advantages of simple structure and good mechanical property, three or more than three high-density polyester round filaments are twisted and stranded in a spiral mode by adopting a rope making machine to form a hard rope, and the V-shaped belt is made of the hard rope serving as a framework material, so that the tensile strength and the transverse rigidity can be improved, and the service life of a product is prolonged.
In the foregoing description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present utility model is not limited to the specific embodiments disclosed above.
