Description

Technical Field

[0001] The utility model relates to the technical field of fiber processing, in particular to a fiber resin twisting device. Background Art

[0002] How to effectively improve the performance of road engineering materials is one of the problems that urgently need to be solved in the field of road engineering. A large number of scientific studies and engineering practices have shown that adding fibers to asphalt mixtures and cement concrete can effectively enhance the various properties of the road surface. The existing basalt fibers used in engineering are mainly chopped basalt fibers. Basalt is melted into a high-temperature melt, and the molten basalt is sprayed from the bottom with the help of wind or gas nozzles to form fibers. The fibers are stretched at high temperatures to make them longer, and the surface coating is treated with a wetting agent to enhance the waterproofness and chemical stability. The fibers are cut to the required length by precision cutting equipment. As a high-performance inorganic fiber, it has been used by many scholars in asphalt mixtures and cement concrete to improve their road performance. However, the surface of basalt fiber is inert, the surface energy is low, and the low interfacial bonding strength limits its improvement of the toughening performance of the road surface. Compared with structurally stable fibers, resins and fiber-resin interfaces are more susceptible to environmental influences, and the coating on the fiber surface fails prematurely, causing the fiber asphalt mixture and fiber concrete to be destroyed prematurely before they can fully function.

[0003] Therefore, in order to increase the service life of fibers in pavement engineering, strengthen the toughening effect of fibers in asphalt mixtures and cement concrete, and further improve the performance of organic and inorganic fibers such as basalt fibers, it is necessary to develop a basalt fiber resin twisting device for road engineering.

[0025] like Figure 1 A basalt fiber resin twisting device for road engineering shown in the figure comprises:

[0026] A wire storage device 100 for winding the wire harness to be processed;

[0027] The wire harness slurry box 200 is arranged at the rear end of the wire storage device 100 and is used for slurrying the wire harness;

[0028] The wire twisting device 300 is arranged at the rear end of the wire bundle slurry box 200, and is used to twist the multiple wire bundles after slurry into one strand;

[0029] A drying device 400 is provided at the rear end of the stranding device 300 and is used to dry the stranded wire bundle;

[0030] The cold drying device 500 is arranged at the rear end of the drying device 400 to dry the wire harness naturally;

[0032] Specifically, the wire storage device 100 outputs a plurality of wire harnesses, which are coated with slurry through the wire harness slurry box 200, and the coated plurality of wire harnesses are twisted into one wire through the twisting device 300, and then enter the drying device 400 for drying, and the dried wire harnesses enter the cold drying device 500 for natural cold drying, and the cold dried wire harnesses are wound up through the wire winding device 600.

[0033] Furthermore, the wire harness slurry box 200 includes a slurry box 201 , a plurality of wire guides 202 are arranged side by side on the top of the front end of the slurry box 201 , and a rubber slurry restraining port 203 is arranged at the rear end of the slurry box 201 .

[0034] Specifically, the multiple wire harnesses released from the wire storage device 100 enter the slurry box 201 through the wire routing device 202 respectively, and the wire harnesses soaked in resin are sent out from the rubber slurry restraint port 203.

[0035] It should be noted that the wire routing devices 202 arranged side by side facilitate the full contact between multiple wire harnesses and the resin, thereby ensuring the wrapping effect; the rubber slurry restraint port 203 is a rubber sleeve, and a through hole is provided in the center of the rubber sleeve for a single wire harness to pass through. Excessive glue is blocked by the rubber slurry restraint port 203, thereby ensuring that a layer of resin is evenly wrapped around the periphery of the passing wire harness.

[0037] It should be noted that the wire bundle wrapped with resin is twisted into a whole strand by the twister 302, and the speed of the first variable speed motor 301 is adjustable. The surface ribbed stripes of the basalt fiber can be adjusted to a certain extent by adjusting the speed, and the groove structure on the fiber surface can be regulated. These groove structures increase the roughness of the fiber surface, which can enhance the mechanical meshing effect between the fiber and the asphalt mixture or cement slurry, and can significantly improve the bonding performance between the fiber and the asphalt or cement matrix.

[0044] Specifically, the second variable speed motor 602 can adjust the speed by adjusting the voltage, thereby adjusting the speed of fiber winding.

[0045] The working process of this embodiment is as follows:

[0046] (1) Place the fiber on the creel, fix it firmly, adjust the height of the support, pull out 4 strands of fiber from the accumulator 100, and connect them to the wire bundle slurry box 200;

[0047] (2) The twisted fibers are fully in contact with the resin through the bundle slurry box 200. The rubber slurry restraint port 203 can scrape off excess slurry and then enter the twister 302. The speed is driven synchronously by the first variable speed motor 301 through the crawler. Four strands of wire enter and are twisted into one strand at the outlet.

[0048] (3) The degree of twisting is controlled by the first variable speed motor 301 to form a plurality of twisting structures, thereby realizing ribbed stripes on the fiber surface;

[0049] (4) After passing through the drying device 400, the resin-twisted fibers are heated and dried, and then connected to the cold drying device 500 to dry in air;

[0050] (5) The dried wire bundle enters the take-up drum 601, and is driven by the second variable speed motor 602 through the crawler belt to rotate synchronously to obtain a fiber spool;

[0051] (6) The size of the fiber spool can be adjusted by the second variable speed motor 602, and after being removed, the length of the fiber for road engineering can be obtained by a precision cutting machine.

[0052] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
