All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to solve the problems that the gabion mesh is easy to rust and age, low in acid and alkali resistance, weak in corrosion resistance, short in service life and complex in production flow, the method for weaving the gabion mesh by using the polyester yarns and setting the functional mechanism is adopted, so that various performances of the polyester gabion mesh are improved, and the production flow is simpler and more direct.

A method for producing a polyester gabion mesh comprises the following steps:

the method comprises the following steps: the polyester yarn is carded, installed and drawn, the net pulling mechanism comprises a front creel and a rear creel, the polyester yarn with the diameter of 2.5-4.0 mm is wound on a yarn shaft of the front creel, and the polyester yarn with the diameter of 3.5 mm in the embodiment has better high-temperature stability. A gravity weight is hung between the polyester yarn and the shaft bracket. The gravity drop can ensure that the silk thread is straightened under certain tension, and normal production is prevented from being influenced by bending due to stress.

And (3) simultaneously rotating the filament shafts of the front row of filament frames along with the rotating frequency of the main machine for twisting the polyester gabion mesh to comb the polyester filaments. Each wire shaft of the front wire arranging frame is arranged in the middle of a big gear with the diameter of about 0.6 m. When the bull gear rotates, the teeth of the bull gear drive the wires of the rear wire frame to rotate around the wire shafts of the front wire frame, and the wires of the front wire frame are kept not to rotate. The large gear rotates, and the screw shaft arranged on the large gear does not rotate because the screw shaft is arranged on a circular iron ring which is arranged in the middle of the large gear. The balance weight is arranged on the iron ring, and the outer ring keeps smooth, so that the large gear is ensured to rotate, and the screw shaft arranged on the gear does not rotate. The wire of the rear wire arranging frame passes through the round holes of the device swinging up and down and swinging left and right when passing through the front wire arranging frame, and the wire of the rear wire arranging frame is driven by the gear wheel on the upper part to be wound with the wire shaft on the upper part firstly when swinging up and is driven by the gear wheel on the lower part to be wound with the wire on the lower part when swinging down. The same effect is achieved by swinging left and right, so that the polyester yarns are straightened and ordered. The polyester thread is drawn out by a traction frame on the rear wire frame, and the thread is drawn to a thread rolling and twisting mechanism.

Step two: and (3) twisting the polyester wires of the gabion mesh by a twisting mechanism, twisting the drawn wires by a twisting plate and twisting mechanism, and weaving the wires into a mesh. The former group is used to weave the wires into a net and the latter group is used to wind the wires synchronously.

The thread rolling and twisting mechanisms are divided into two groups and are respectively arranged in the two groups of beams at the front and the back of the frame and comprise an upper sliding plate, a lower sliding plate, a rack and a thread twisting wheel group, elongated slots along the length direction of the upper sliding plate and the upper sliding plate are respectively arranged on the lower part of the upper sliding plate and the upper part of the lower sliding plate, polyester threads penetrate through the elongated slot rack arranged on the lower sliding plate, and the threads synchronously encircle under the driving of the rack. The wire twisting wheel set comprises a plurality of wire twisting wheels, each wire twisting wheel is composed of an upper half wheel and a lower half wheel, polyester wires penetrate through wire penetrating holes in the upper half wheel and the lower half wheel, the wire twisting wheels and racks are meshed with each other and are driven by the racks to rotate, the polyester wires are woven into an ordered and regular net shape through the rotation of the gears of the wire twisting wheels, and every two adjacent wires of the polyester gabion net are twisted alternately to produce the gabion net.

Step three: the gabion mesh is shaped, the power distribution mechanism is arranged at one end of the rack and used for distributing power for each component, and the power distribution mechanism comprises a gear transmission mechanism, a cam transmission mechanism and a sliding plate driving mechanism and distributes power for each mechanism to enable each mechanism to complete corresponding functions. The polyester yarn is driven by the sliding plate driving mechanism to do intermittent reciprocating motion by the upper sliding plate and the lower sliding plate. The shaping mechanism comprises a shaping roller and a heating device.

The pull roll pulls the web onto the sizing roll, and the web is heated by a heating device around the bottom of the sizing roll. The heating device is an electric heating tube, the temperature of the electric heating tube is 150-. The metal roller is internally heated, the electric heating pipe is arranged inside the roller, the electric heating pipe is electrically conducted by the collecting ring, and when the temperature reaches the required temperature, the machine can be started for production. After the polyester gabion mesh is twisted and formed, the roller has the function of pulling power, and meanwhile, the polyester gabion mesh is influenced by high temperature when passing through the surface of the roller, so that the effect of heating and shaping is achieved.

Step four: and withdrawing the gabion net, drawing the gabion net woven by a plurality of polyester silk yarns into a shaping roller of the shaping mechanism through the net drawing mechanism in front to flatten the gabion net, eliminating stress, and drawing the net piece into a net collecting mechanism through an upper net pressing roller and a lower net pressing roller.
