Description

The inventive utility model relates to technological lines intended for the manufacture of non-metallic reinforcing elements, and can be used for reinforcing conventional and prestressed building structures.

A known production line for the manufacture of non-metallic reinforcement according to the patent of the Russian Federation No. 2075577, MKl E04C 5/07 (publ. 03/20/1997), including creel with installed roving bobbins, annealing chamber, impregnation chambers with a tension device, molding unit with a block die, pre-polymerization chambers with wrapper, polymerization chambers, units for winding and cutting reinforcement, pulling device, tension blocks mounted on the creel after each bobbin, leveling device installed in front of the camera from firing and modular device interacting with tension blocks. located after the impregnation chamber, while the creel axes are rotatable, and the impregnation chamber has a fluoroplastic coating on the inner walls and the bottom, made with a slope to the center of the chamber. The leveling device is made in the form of a comb provided with porcelain inserts. The block of the dies of the molding unit is made of fluoroplastic, the annealing chamber is equipped with a high-frequency heater and is configured to operate in a pulsed mode. The processing line is equipped with a unit for applying an adhesive or film coating.

The disadvantage of this technical solution is the complexity and low productivity of the line, as well as the inability to obtain composite reinforcement with high anchoring properties.

Also known is a technological line for the manufacture of non-metallic fittings (Frolov NL "Fiberglass reinforcement and glass-concrete structures", Moscow, Stroyizdat, 1980, pp. 20-24), including creel with roving bobbins, leveling device, annealing chamber, impregnating bath with tensioning device, squeezing device, molding unit, spiral winding device, polymerization chambers, pulling device, cutting and reeling units. The disadvantage of this technological line is its complexity and insufficiently high productivity.

The closest design to the claimed technical solution is a production line for the manufacture of non-metallic reinforcement, including sequentially installed creel with roving spools, leveling device, annealing chamber, impregnating bath with a tension device, squeezing device, molding unit, spiral winding device, polymerization chambers, pulling device , a winder of a winding bundle, a cutting and reeling unit (RF patent No. 2287646, MKL. ЕСС 5/07, published November 20, 2006. The disadvantage of this oystva is its low productivity, as well as a limited range of manufactured non-metallic reinforcement. The technical problem to be solved by the proposed ,, useful model is to increase the line speed, as well as providing the possibility of expanding the size range of manufactured valves.

The problem is solved due to the fact that the production line for the manufacture of non-metallic reinforcement, including serially installed creel with roving bobbins, leveling device, annealing chamber, impregnation bath with a tension device, squeezing device, molding unit, spiral winding device, polymerization chamber, pulling device , the winder of the winding bundle and the cutting and reeling unit, is equipped with a water cooling unit installed between the polymerization chamber and the pulling device tion, the polymerization chamber length is increased, and the molding unit comprises molding disk configured with uniformly-spaced around the periphery of the through holes and connected with a bracket forming a cylindrical tube, the end of which a removable hollow tip installed.

The production line differs from the known one in that it is equipped with a water cooling unit located between the polymerization chamber and the hauling device. The presence of this node provides rapid curing of the reinforcement before entering the haul device, which is important for maintaining its cylindrical shape.

The implementation of the molding disc with through holes evenly distributed along the periphery allows separating, and then, excluding twisting, uniformly feeding the roving throughout the entire volume into the molding tube, which guarantees the production of reinforcement with specified technical characteristics. Placing a replaceable tip at the end of the molding tube provides an extension of the range of manufactured products.

An increase in the length of the polymerization chamber allows the manufacture of non-metallic reinforcement of large diameters with high performance.

Due to the presence of these signs, the productivity of the proposed production line for the manufacture of non-metallic fittings is increased, and it is also possible to expand the size range of the manufactured fittings.

The proposed device is illustrated by the drawings shown in Fig 1, 2.

Figure 1 shows a diagram of a technological line for the manufacture of non-metallic fittings,

Figure 2 shows the molding unit

The technological line for the manufacture of non-metallic reinforcement consists of sequentially installed creel with roving bobbins 1, leveling device 2, annealing chamber 3, impregnation bath 4 with tension device 5, squeezing device 6, molding unit 7, spiral winding device 8, polymerization chamber 9, unit water cooling 10, the pulling device 11, the winder of the winding bundle 12, the cutting and reeling unit 13. The forming unit 7 includes a forming disk 14 (Fig. 2) made with through holes the periphery 15 and connected by brackets 16 to the forming cylindrical tube 17, which has a removable hollow tip 18.

A technological line for the manufacture of non-metallic reinforcement operates as follows. Rings from mineral (glass, basalt, carbon, etc.), polymer (nylon, polyester, etc.), as well as vegetable fibers from bobbins 1 pass through the rollers of the tensioning device and leveling device 2, which carries the additional function of separating the roving canvas into separate bundles . The leveling device 2, made in the form of a comb, forms bundles of rovings entering the annealing chamber 3, in addition, it carries an additional separation function, which is necessary so that the roving bundles do not become entangled. In the annealing chamber 3, moisture is removed at a processing temperature of 150-250 ° C. Then the roving bundles enter the impregnation bath 4, filled with a polymer binder with a temperature of 40-60 ° C, and the tension device 5, having a control mechanism for the convenience of controlling the tension of the threads, is located above the impregnation bath 4. After the impregnation bath 4 roving bundles pass through the squeezing device 6, which is made of elastic elastic material and is designed to squeeze excess binder from the beams back into the impregnation bath 4. Next, the roving bundles through the holes 15 of the forming disk 14, located laid on the periphery of the latter, without tangling, enter the molding cylindrical tube 17 and through the tip 18, taking a cylindrical shape, enter the spiral winding device 8, where they are wrapped with a bundle of the same material, as a result of which a rod with a periodic profile of the reinforcement is formed. For the formation of a clearly defined periodic profile of the reinforcement, the winding rope must be round in cross section and of sufficient diameter to form a relief. The depth of indentation of the winding bundle is regulated by compressing the spring on the coil with a roving on the spiral winding device 8. The optimal depth of indentation of the bundle into the rod is half the diameter of the bundle, which ensures good adhesion of the bundle to the rod and reinforcement with concrete. The impregnation of the winding rope with a polymer binder is carried out due to excess resin in the reinforcement array.

The distance from the tip 18 to the place of winding should be within 2-3 diameters of the manufactured reinforcement, which ensures a snug fit and indentation of the winding cord, and also prevents twisting of rovings, which can degrade the quality of the reinforcement. This distance is adjusted manually.

Next, the rod enters the polymerization chamber 9, where it is exposed to temperatures up to 400 ° C for 1 min. 10 sec up to 1 min 30 sec from where it is pulled through the water cooling unit 10 by the pulling device 11 and fed to the winder of the tow 12 and the cutting unit of the reinforcement 13.

An advantage of the claimed production line compared to the known ones is a significant increase in its productivity, in addition, non-metallic reinforcement of various diameters from 3 mm to 18-20 mm is provided.
