Description
Technical field
The utility model relates to a kind of device that on the flexible rapier loom sword belt is pressurizeed that is applicable to, the flexible pressue device of especially a kind of sword belt.
Background technology
Figure 1 shows that the sword belt pressue device on a kind of existing Rapier looms, it comprises the sword belt 12 that is connected with sword head 11 by, this sword belt 12 can slide in sword belt guide rail 13, one sword wheel 14 links to each other with frame by bearing, and can do the dead axle rotation around the O point, and sword belt 12 is by sword belt briquetting 15 fixings that are positioned at A, B two places, see shown in Figure 2, wrap on the sword wheel 14, drive motion by sword wheel 14, sword belt briquetting 15 is fixed on the frame; An end that is not connected with sword head 11 on the sword belt 12 stretches in the sword storehouse 16, can slide in sword storehouse 16.Sword belt 12 transfers circular motion to by rectilinear motion, transfers rectilinear motion again to, and the turning point of its motion is A, B 2 points, locates must apply an external force A, B at 2, and its direction along regulation is moved.
The pressure point of 15 pairs of sword belts 12 of sword belt briquetting: one is the place, point of contact of the extension line and the sword wheel 14 of sword belt guide rail, and two is the place, point of contact of the extension line and the sword wheel in sword storehouse.The shortcoming of said structure is: the one, there is sliding friction between sword belt briquetting 15 and the sword belt 12, locate exist bigger pressure A, B at 2 between sword belt 12 and the sword belt briquetting 15, factors such as the rigidity of cornerite on the sword wheel of this pressure and sword belt, sword belt, sword wheel diameter are relevant, when using carbon fibre sword belt, pressure ratio on the sword belt briquetting 15 is bigger, and is just relatively more serious if speed of related movement than very fast, generates heat herein, the temperature that is in operation causes damage phenomenons such as sword belt comes unstuck, peeling than higher; The 2nd, the frictional force between sword belt briquetting 15 and the sword belt 12 is big, and sword belt briquetting 15 or sword belt 12 serious wear are damaged sword belt, increase the maintenance cost of loom; The 3rd, between sword belt briquetting 15 and sword belt 12, need to reserve a certain amount of gap delta, to adapt to the round runout error in footpath, the sword wheel end, the δ amount can not be too big, and correspondingly the accuracy of manufacture in footpath, the sword wheel end requires also to damage sword belt easily than higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, easy to use, reliable, and not easy to wear, use cost is low, the flexible pressue device of the sword belt that running precision is high.
The purpose of this utility model city finishes by following technical solution, it includes frame, one surrounds the sword wheel upward and by it drives the sword belt of operation, at least two contact point or contact areas with the sword wheel that it is characterized in that described sword belt are provided with flexible rolling mechanism, and described sword belt is pressed on the described contact point of sword wheel or comprises described contact point on an interior arc contact area.
Described sword belt front end is fixed with the sword head, and by a sword belt guide rail, the other end of described sword belt stretches in a sword storehouse and can slide in the sword storehouse; With described to hold two contact points of sword wheel or comprise described contact point be the motion turning point of sword belt at interior arc contact area, and described two motion turning points are provided with flexible rolling mechanism on the described sword belt.
Described flexible rolling mechanism mainly comprises a solderless wrapped connection on expansion tightening wheel and idle pulley, and by the flat belt of its tensioner, and this flat belt presses on described sword belt; The center of described expansion tightening wheel and idle pulley is with respect to the position-adjustable of frame.
Described flat belt is described motion turning point or the arc pressurised zone that comprises described motion turning point to the pressurization scope of described sword belt, described motion turning point is meant: the one, and the place, point of contact of the extension line of sword belt guide rail and sword wheel, another is the place, point of contact of the extension line and the sword wheel in sword storehouse.
The utility model is a kind of improvement to prior art, and its design feature is:
1, employing is coated on expansion tightening wheel and the idle pulley, and sword belt is pressurizeed by the flat belt of the flexibility of expansion tightening wheel tensioner, be used for changing the direction of motion of sword belt, in the motion process of sword belt, no relative slip between pressurized part (flat belt) and the sword belt, there is not relative slip between flat belt and expansion tightening wheel and the idle pulley yet, just there is not friction yet, have only in the rolling bearing on expansion tightening wheel and the idle pulley rolling friction is arranged, greatly improved the suffered frictional resistance of sword belt, also improve simultaneously the temperature rise on the sword belt pressure point, prolonged the service life of sword belt.
2, Rou Xing flat belt is good to the pressurization surface self-adaption of sword belt, and is lower to the requirement of beating directly of the sword wheel end, reduced manufacturing cost.
3, Rou Xing flat belt can be regulated as required to the pressurization area of sword belt, and pressure point can be one section arc surface.
4, the position of expansion tightening wheel and idle pulley is as long as guaranteeing flat belt and sword belt is close to, and an end of flat belt is parallel with sword belt guide rail or sword storehouse inlet, and other position accuracy demand are not high, install easily and adjust.
The utlity model has simple in structurely, easy to use, reliable, not easy to wear, use cost is low, characteristics such as running precision height.
