Description

A kind of shedding mechanism that is used to produce heavy filter cloth loom

Technical fieldThe utility model relates to the equipment of weaving cotton cloth, and more particularly relates to a kind of shedding mechanism that is used to produce heavy filter cloth loom.

Background technologyAt present, China mainly is to lean on import to solve at widely used belt filter clothes in field such as metallurgy, chemical industry, oil, and China does not also have the equipment of weaving cotton cloth of special production belt filter cloth at present.In order to address the deficiencies of the prior art, consider from the economical and energy saving angle, existing equipment such as the double-lift multi-arm heald frame elevating mechanism weaving machine of weaving cotton cloth transformed innovation, the shedding mechanism that is used to produce heavy filter cloth loom is transformed.

Summary of the inventionIn view of the defective that prior art exists, the exploitation of the utility model has solved the plant issue that China produces 3/3 latitude two-fold belt filter cloth, the history of the belt that is through with filter cloth import; Adopt the mode of technological transformation, cost is lower, implement easier.

For realizing above-mentioned purpose, the technical solution that the utility model adopted is: driving gear is fixed on the initiatively left side of bent axle, driven shaft and the initiatively parallel placement of bent axle, and driven gear is fixed on the left side of driven shaft and is meshed with driving gear; Left gear on upper left gear, left lower gear, left internal gear and the lower-shaft constitutes left change-speed gearing group; Right gear on upper right gear, bottom right gear, right external gear and the lower-shaft constitutes right change-speed gearing group, wherein left lower gear, left internal gear, bottom right gear, right gear be fixedly mounted on be on the axle coaxial; Upper left gear, upper right gear are fixed on the right and left position of driven shaft; Left gear, right gear are fixedly mounted on the right and left position with the lower-shaft of the parallel placement of driven shaft in the change-speed gearing group; Two side ends at lower-shaft fixedly is equipped with six shedding cams respectively, and the profile of shedding cam is that the little arc surface that limited two 140 ° ± 5 ° angle of repose and great circle cambered surface and two 40 ° right transition circle cambered surface, left transition circle cambered surface constitute; The profile of shedding cam contacts with rotor on being arranged on treading rod, and an end of treading rod places on the axle bed of frame, and the other end of treading rod is connected with heald frame via set screw, and the upper end of heald frame is lifted on the frame top through spring.

Upper left gear, upper right gear are fixed on the driven shaft, and axle is provided with coaxial left lower gear, left internal gear, bottom right gear, right external gear, and left gear, right gear are fixedly mounted on the lower-shaft, and shedding cam is located at the two side ends of lower-shaft.Rotor is fixed on the treading rod.

Under the effect of power; Initiatively bent axle drives the driving gear rotation; The driven gear that warp is meshed with driving gear drives driven shaft; In-line gears left side lower gear on the gear band moving axis that is fixed on the driven shaft, left internal gear, bottom right gear, right external gear are rotated, and in-line gears drive the gear that is fixedly mounted on the lower-shaft and rotate, and lower-shaft also rotates thereupon; Thereby the shedding cam that drives the lower-shaft two side ends rotates.

Shedding cam is to act on the rotor that is fixed on treading rod with right transition circle cambered surface, and treading rod drive heald frame moves downward under the effect of shedding cam.

Shedding cam is to act on the rotor that is fixed on treading rod with left transition circle cambered surface, because the pulling force of spring makes heald frame begin to rise together with treading rod.The operation that state among Fig. 2 and Fig. 3 goes round and begins again.

Because the utility model has solved the plant issue that China produces 3/3 latitude two-fold belt filter cloth, the history of the belt that is through with filter cloth import; Adopt the mode of technological transformation, cost is lower, implement easier, is a kind of transformation of shedding mechanism that is used to produce heavy filter cloth loom with promotional value.
