Technical Field

The invention relates to the technical field of gabion mesh manufacturing equipment, in particular to a Polyester (PET) gabion mesh winding device.

Background

The polyester gabion mesh has the characteristic of polyester wires, and can be normally used in an environment with the temperature of minus 50 ℃ to minus 150 ℃ without change of physical properties. The polyester gabion mesh is light in weight, only 5 times of the iron wire in weight, and is convenient to transport. Meanwhile, the polyester gabion net is not easy to rust, ageing resistant, acid and alkali resistant, corrosion resistant and long in service life, is particularly suitable for being used for aquaculture, side slope support, foundation pit support, mountain rock surface net hanging and guniting, side slope vegetation (greening) and railway highway isolation guardrail nets along a river and sea area, can be woven into net cages, net mats and anti-scouring protection for rivers, dams and sea ponds, and can be used for reservoir and river cut-off net cages, so that the river bed can be protected for a long time, energy conservation and environmental protection, and can be recycled. The polyester gabion mesh is applied to forests, mountainous regions (particularly high mountain areas) and transformer substations as a fence mesh due to the non-conducting characteristic, and the danger of lightning stroke can be avoided in thunderstorm strong convection weather.

But the existing gabion mesh machine cannot produce and process the gabion mesh made of the material. The existing gabion mesh machine can only process gabion meshes made of metal wires, and because the physical properties of polyester materials cannot be changed in the environment from minus 50 ℃ to minus 150 ℃, the polyester materials cannot be processed into spring wires like the metal wires, even if the spring wires are processed at high temperature, the spring wires are wound due to stress influence when being woven, and cannot be processed like the metal wires.

In the whole process, the rear group of the washboard thread twisting mechanisms 12 and the front group of the washboard thread twisting mechanisms 12 always move synchronously, so that threads between the front group of the washboard thread twisting mechanisms 12 and the rear group of the washboard thread twisting mechanisms 12 are not wound mutually. The thread behind the latter set of thread rolling and twisting mechanisms 12 also requires a synchronized movement of the thread 4 relative to the upper slide plate 27 and the lower slide plate 28 and the rotation of the twisting wheel in order to avoid twisting.

When the upper slide plate 27 and the lower slide plate 28 move to enable the upper half bearing and the lower half bearing to be mutually buckled, the control cylinder 11 enables the front upper and lower traction frames 8 to move to the upper side, the rear upper and lower traction frames 6 to move to the lower side, the left and right traction frames 9 move to the leftmost side, then the upper half wheel 29 and the lower half wheel 30 are combined into a twisting wheel and driven by the rack 22 to rotate, at the moment, the controller synchronously starts the motor on the fixed-thread shaft frame 5, the motor drives the fixed-thread shaft rotating wheel 21 to rotate through the driving wheel 33 and the driven wheel 23, the fixed-thread shaft rotating wheel 21 drives the threads 4 clamped on the teeth to rotate around the fixed-thread shaft rotating wheel 21, and the rotating speed and the rotating direction of the fixed-thread shaft rotating wheel are. Then the upper sliding plate 27 and the lower sliding plate 28 of the thread rolling and twisting mechanism 12 move back to back, the upper half wheel 29 and the adjacent other lower half wheel 30 form a thread twisting wheel, at this time, the front upper and lower traction frames 8 move to the lower part, the rear upper and lower traction frames 6 move to the upper part, the left and right traction frames 9 move to the rightmost side, and the threads 4 pulled by the traction screws 10 on the front upper and lower traction frames 8, the rear upper and lower traction frames 6, the left and right traction frames 9 are clamped on the teeth of the other fixed thread shaft rotating wheel 21 in the two corresponding fixed thread shaft rotating wheels 21. Then the twisting wheel is driven by the rack 22 to rotate, at the moment, the controller synchronously starts the motor on the fixed-thread shaft frame 5, the motor drives the fixed-thread shaft rotating wheel 21 to rotate through the driving wheel 33 and the driven wheel 23, the fixed-thread shaft rotating wheel 21 drives the threads 4 clamped on the teeth to rotate around the fixed-thread shaft rotating wheel 21, and the rotating speed and the rotating direction of the fixed-thread shaft rotating wheel are synchronous with the twisting wheel. The reciprocating motion is carried out, so that the silk thread 4 between the net pulling mechanism and the net weaving mechanism is not wound during the net weaving operation, and the normal processing production is not influenced.

The present invention is not limited to the above-described embodiments.
