AI Technical Summary
The positioning needles of the existing hook net machines use a ‘collision’ transmission, resulting in high noise, short service life, and slow rebound speed of the positioning needle, which requires alternating movement of double needles to achieve function.
A single positioning needle is used to drive through a rope to replace the original two positioning needles, reduce noise and increase rebound speed, and use a single needle to realize the original double needle function.
It significantly reduces noise, extends the service life of the components, and increases the rebound speed of the positioning needle, so that the performance of the single-needle hook net machine is close to or exceeds that of the double-needle hook net machine.

Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of chain link fence machines, and in particular relates to a single-needle chain link fence machine. Background Art
[0002] Chain link fence machine is also called diamond mesh machine, coal mine support mesh machine, anchor mesh machine, chain link fence machine product display machine, mesh weaving machine. Chain link fence machine is a wire mesh machine that weaves low carbon steel wire, stainless steel wire, aluminum alloy wire, PVC wire, sprayed wire into a chain link fence. The net has uniform mesh, flat surface, beautiful appearance, adjustable width, adjustable wire diameter, not easy to corrode, long life, simple weaving, beautiful and practical.
[0003] At present, most of the chain link fence machines on the market are "collision type". As you can imagine, the "collision type" drives the positioning needle to move through collision during operation, which makes a lot of noise and has a short service life. Figure 7 As shown, the positioning needle of the existing chain link fence machine is a double needle type, and the two positioning needles can realize its positioning function by alternating motion. Each positioning needle is connected by a connecting rod, and the middle part of the connecting rod is fixed on the rotating sleeve, and the rotating sleeve is connected to the installation shaft. The other end of the connecting rod is provided with a bearing, and a collision block is provided above the bearing. Its working principle is: the installation shaft reciprocates with the netting frame, and the connecting rod reciprocates under the drive of the installation shaft. When the bearing of the connecting rod collides with the collision block above. The connecting rod will rotate, and the positioning needle will be lifted. When the bearing passes the collision block, the connecting rod returns to its position and the positioning needle falls. Therefore, this type of chain link fence machine is mostly called "collision type". There will be a lot of noise during the reproduction process, and it is easy to cause damage to the components, and the life is relatively short. In addition, since it takes a certain amount of time for the bearing to pass, the rebound speed of the positioning needle is slow, so it is necessary to use double needles to alternately act to realize the function.
