Description

High-speed knitter

Technical field

The utility model relates to the high-speed knitter tool that a kind of metal wire knitted becomes cable, belong to cable knitting skill field.

Background technology

Along with this world's community of China's entry into the WTO, increasing international well-known large enterprises settle China one after another, for having brought international advanced person's technology and up-to-date product in the domestic market, the use in the communications field to shielding wire is more and more, and is also more and more higher to the quality requirement of shielded cable.In the high-speed knitter in the market, product, the domestic product that producers such as Guangdong Jiamei, Nan Yang, Shanghai, northwest Machines Plant are arranged of U.S. Wo Deweier company, German Si Boka company arranged abroad.Its main product structure is formed and is comprised compositions such as frame, motor and transmission mechanism, and from operating position, the performance of imported product is more stable, but the complex structure of product costs an arm and a leg, and accessories shortage, valency height, and it is very inconvenient to keep in repair.The home products relative price is cheap, but the product that has is because of design and the reason made, and main transmission part hardness or rigidity are not enough, and yielding damage, noise are big; The product that has is regulated inconvenience or poor stability because of the spindle governing mechanism of tension, and the material of braided wires, the range of application of diameter are narrower, can not satisfy user's requirement fully; The product that has is selected for use improperly because of part material, and tracks is more easy to wear, has influenced service life; The product that has also lacks due safety device; Accident warning device; Regularly, measured lubrication device etc., these deficiencies all will make the performance of machine reduce.On the Chinese patent communique, also there is similar patent application technology open, as ZL03211771.4 and 03270225.6 or the like.

Summary of the invention

The purpose of this utility model be to provide a kind of rational in infrastructure, compact, safe and reliable to operation, easy to operate, noise is lower, the high-speed knitter of dependable performance.It mainly is made up of frame, motor and transmission mechanism, described transmission mechanism comprises a power input shaft that links to each other with the frequency conversion three phase electric machine at least, be fixed with a pair of spiral bevel gear on this power input shaft, and link with following pallet by another double helix bevel gear and the top tray of engagement respectively, last ingot is distributed on the top tray, and following ingot is distributed on down on the rotating disk edge that links to each other on the pallet.

A described spiral bevel gear links to each other with following pallet by a middle spindle drum, and fixing rotating disk up and down ingot also is fixed with fork and swing rod together on following pallet, and top tray is rotated with different speed with following pallet.

Described power input shaft is meshing with each other with spiral bevel gear on being connected in power output shaft one end by spiral bevel gear and links to each other with power output shaft, power output shaft links with the worm screw of the traction wheel of ining succession mutually by speed change change gear and a pair of commutation bevel gear.

The utility model belongs to the improvement to prior art, and it has rational in infrastructure, compact, and is safe and reliable, noise is lower, dependable performance; Can adopt PLC programming Control technology and touch screen operation, easy to operate, parameters comes into plain view; Can regulate by gear and adjust the weaving thread tension, adjustable range is between 0.5-5N, after adjusting to suitable tension, it is constant to utilize the pressure angle self-lock mechanism to make it tension, guaranteed the work reliability of operation, improve the service life of transmission mechanism, can improve the characteristics such as the life-span quality of production of product.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model is selected a frequency conversion three phase electric machine (not shown) for use, link to each other with power input shaft 2 by pulley concial disk 1, and give power input shaft 2 with transmission of power, be fixed with a pair of

spiral bevel gear

3,4 on the power input shaft 2, and link by another double

helix bevel gear

5,6 and top tray 7 and the following pallet 8 of engagement respectively; Wherein going up ingot is distributed on the top tray 7; And pallet 8 is to link to each other with spiral bevel gear 6 by a middle spindle drum 9 down, be fixed with rotating disk 10 on the pallet 8 down, be fixed with down ingot, fork and swing rod on the edge of this rotating disk, following ingot weaving thread swung up and down by the cycle of fork, and the swing of fork is to realize by the slip of the nylon slide block on the fork in groove circle groove.Gear ring is fixed on the top tray 7, because the gearratio difference, top tray 7 is rotated with different speed with following pallet 8.Last ingot on the rotating disk guide rail of otch around central slide, for helping the swing of fork, into rotating disk guide rail notch is shown or put to following ingot weaving thread, go up simultaneously ingot just in time pass by down the following of ingot weaving thread or above, clocklike repeat this process, 2 folded 2 braid has just formed.

Described power input shaft is meshing with each other with spiral bevel gear 12 on being connected in power output shaft 11 1 ends by spiral bevel gear 6 and links to each other with power output shaft 11, power output shaft is by speed change change gear and a pair of commutation bevel gear, link with the worm screw 14 of the traction wheel 13 of ining succession mutually, worm screw 14 drives traction wheel 13, comes the synchronous line that braiding is come out of collecting.

Main frame is placed on the frame, is driven by variable-frequency motor, and in order to have a machine in operation steadily, main transmission has all adopted Helical Bevel Gear, low, the long service life of noise.

Braiding fork rotating part can design high-precision axle journal, bearing shell.In the operation of a machine process, the stationarity and the reliability of fork motion can be greatly enhanced.
