Abstract
The utility model relates to a hydraulic loom pumping cam mechanism, including cam pendulum rod and the pumping cam that contacts with cam pendulum rod one end, the pumping cam set up to the eccentric structure with cam rotation direction reverse direction radius crescent, the cam mid portion is provided with the shaft hole, the cam pendulum rod sets up in pumping cam below, the cam pendulum rod is provided with a rotatable annular cover with the one end that the cam contacted is spread to the pump. The pumping cam of the utility model is of an eccentric structure, when the cam rotates at a certain rotating speed, the cam is gradually contacted with the swing rod, so that the vibration phenomenon can not be caused, and the water pump cannot pump water unevenly due to vibration; and the end of the cam swing rod contacting the cam is provided with an annular sleeve capable of automatically rotating, so that the cam does not fall on one point when contacting the swing rod in the rotating process of the cam, the abrasion between the cam and the swing rod is reduced, and the service life is long.
Description
Technical field
The utility model relates to water jet looms, is specifically related to a kind of spraying driving device for water of water jet looms.
Background technology
In textile industry, in the process that water jet looms is weaved cotton cloth, need when weaving cotton cloth, spray water, usually adopt water pump to spray water, because water pump generally leans on cam driven cam swing drive work, but because of day between cam and the fork producing vibration, thereby make water pump fetch water, when spraying water, rhythm is inhomogeneous, and it is also just inhomogeneous to spray water, the quality that influence is weaved cotton cloth.Produce wearing and tearing because of the collision between cam and the fork makes cam and fork easily again, easily cause the service life of cam and fork short.
The utility model content
The utility model is at the water jet looms above-mentioned deficiency inhomogeneous and that parts are easy to wear, service life is short of spraying water when weaving cotton cloth, provide a kind of make water jet looms water pump water spray evenly, the water jet looms pumping cam mechanism of parts long service life.
The technical solution of the utility model is: a kind of water jet looms pumping cam mechanism, comprise cam swing and with the contacted pumping cam of cam swing one end, described pumping cam is set to and the cam rotation direction eccentric structure that increases gradually of radius in the other direction, the cam mid portion is provided with axis hole, cam swing is arranged on pumping cam below, and cam swing and the contacted end of pump shop cam are provided with a rotating annular cover;
Preferably, described cam swing is set to down " L " shape, and cam swing corner is provided with the cam swing axle;
Preferably, the outstanding end that forms owing to radius increases gradually of described pumping cam has an opening that communicates with camshaft hole.
The beneficial effects of the utility model are: the utility model adopts the pumping cam drive water pump water spray of fetching water, because the pumping cam is set to and the cam rotation direction eccentric structure that increases gradually of radius in the other direction, when cam is pressed certain rotational speed, cam contacts gradually with fork, can not cause the generation of oscillation phenomenon, just can not occur fetching water inhomogeneous because of the water pump that vibration causes, therefore, when the cam driven water pump is fetched water water spray, will make the water pump water spray of fetching water uniformly, thereby guarantee the uniformity of water spray when weaving cotton cloth.And because the end that cam swing contacts with cam is provided with the annular cover, annular cover can rotate automatically, in the cam rotation process, just can not drop on the some when cam contacts with fork, has alleviated the wearing and tearing between cam and the fork, long service life.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model specific embodiment;
Accompanying drawing 2 is the structural representation of the utility model specific embodiment pumping cam.
The specific embodiment
The specific embodiment of the present utility model as shown in the figure: a kind of water jet looms pumping cam mechanism, comprise cam swing 1 and with the contacted pumping cam 2 of cam swing 1 one ends, described pumping cam 2 is set to and the cam rotation direction eccentric structure that increases gradually of radius in the other direction, the cam mid portion is provided with axis hole 3, cam swing 1 is arranged on pumping cam 2 belows, and cam swing 1 is provided with a rotating annular cover 5 with pump shop cam 2 contacted ends; Described cam swing 1 is set to down " L " shape, and cam swing 1 corner is provided with cam swing axle 4; The outstanding end that described pumping cam forms owing to radius increases gradually has an opening that communicates with camshaft hole 6.
During work, 2 uniform rotation of pumping cam, the less part of pumping cam 2 radiuses is contactless with cam swing 1, when pumping cam 2 forwards the bigger part of radius to, pumping cam 2 contacts gradually with cam swing 1, drive cam swing 1 and rotate along cam swing axle 4, an end of the cam swing 1 that makes moves down, and the other end of cam swing 1 then moves to horizontal direction; The plugman 8 that is provided with on the water pump 7 is connected with cam swing 1 by connecting rod piece 9, when cam swing 1 moves, drives plugman 8 by connecting rod piece 9 and moves, thereby drive water pump 7 work.Because pumping cam 2 uniform motion, and contact gradually with cam swing 1, can not produce collision and the vibration that causes, water pump 7 is water spray at the uniform velocity accordingly also, then the water that sprayed of water pump 7 with regard to be sprayed on uniformly weave cotton cloth on.
Claims (3)
1. water jet looms pumping cam mechanism, comprise cam swing and with the contacted pumping cam of cam swing one end, it is characterized in that: described pumping cam is set to and the cam rotation direction eccentric structure that increases gradually of radius in the other direction, the cam mid portion is provided with axis hole, cam swing is arranged on pumping cam below, and cam swing and the contacted end of pump shop cam are provided with a rotating annular cover.
2. water jet looms pumping cam mechanism according to claim 1 is characterized in that: described cam swing is set to down " L " shape, and cam swing corner is provided with the cam swing axle.
