A kind of fly-shuttle loom magnetic control shuttle haulage gear
Technical field
This utility model relates to technical field of textile equipment, is specifically related to a kind of fly-shuttle loom magnetic control shuttle traction
Mechanism.
Background technology
Existing magnetic control shuttle solution is to utilize the S pole permanent magnet bottom shuttle, with the N in traction body
Pole permanent magnet attracts each other, thus the magnetic reached between shuttle with traction body links, and then utilizes track base
On the roller that supports carry out sliding friction with the wear rib on shuttle thus reach control relative distance leading
Draw the power reliable delivery of body to shuttle, and can smooth, high-speed cruising.The design of this technology shuttle requires line
Speed is 12-15m/S, and magnetic attracting pressure requirements reaches 60kg, under this speed and pressure, wear rib with
Holding the roller violent rolling friction of generation thus cause the mechanical friction loss of wear rib greatly, the life-span is low.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that one can alleviate shuttle
And the pressure between supporting rollern, reduces the fly-shuttle loom magnetic control shuttle haulage gear of shuttle abrasion.
For achieving the above object, this utility model employing following technical proposals: a kind of fly-shuttle loom magnetic control shuttle
Haulage gear, including track base and the shuttle being located at track base top, described track base is provided with for supporting
The supporting rollern of shuttle, be provided with in described track base one can in track base along track base length direction slide and
By the traction body driving cable wire to drive, bottom the upper middle position of described traction body and shuttle, centre position is divided
Not being provided with opposite polarity traction permanent magnetic body, the two ends of described track base are provided with driving wheel, described driving cable wire
Walk around driving wheel to be connected with traction body two ends, on the both sides of described shuttle bottom traction permanent magnet and track base with
Corresponding position be provided with the supports permanent magnets of homopolarity.
The two ends of described track base are provided with flap.Traction body arrives the extreme position stopping of track base two ends every time
Time, shuttle due to inertia continue motion, now the bottom of shuttle contacts with flap surface, frictional force with
The lower shuttle of the effect of magnetic attraction stops continuing motion in the shortest distance, uses this technical scheme to make
The timely stop motion of shuttle, prevents shuttle from flying out.
The position that the bottom of described shuttle contacts with supporting rollern is provided with wear rib.
The beneficial effects of the utility model are: increase the homopolarity permanent magnetism that magnetic force repels each other in track base, in shuttle
Body, utilizes magnetic force homopolar-repulsion principle, by shuttle relative to roller pressure reduce, thus reach anti-attrition,
The purpose of low consumption.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
A kind of fly-shuttle loom magnetic control shuttle haulage gear as depicted in figs. 1 and 2, including track base 1 with set
Shuttle 2 in track base 1 top;Track base 1 is provided with the supporting rollern 3 for supporting shuttle 2, guide rail
It is provided with one in seat 1 to slide along track base 1 length direction in track base 1 and by driving cable wire 4 to drive
Traction body 5, bottom the upper middle position of traction body 5 and shuttle 2, centre position is respectively equipped with opposite polarity
Traction permanent magnetic body 6;The two ends of track base 1 are provided with driving wheel 7, drive cable wire 4 to walk around driving wheel 7 and traction
Body 5 two ends connect;Position is corresponded on the both sides of shuttle 2 bottom traction permanent magnet 6 and track base 1
Place is provided with the supports permanent magnets 8 of homopolarity, and the position that the bottom of shuttle 2 contacts with supporting rollern 3 is provided with wear rib
10;The two ends of track base 1 are provided with flap 9.
During use, driving wheel 7 pulls traction body 5 to move back and forth in track base 1, and shuttle 2 leads at magnetic force
Draw follow under effect traction body 5 along support roller 3 move, each traction body 5 arrives track base 1 two ends
When extreme position stops, shuttle 2 continues motion, the now bottom of shuttle 2 and flap 9 table due to inertia
Face contacts, and under the effect of frictional force and magnetic attraction, shuttle 2 stops continuing motion in the shortest distance.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
