Abstract
The invention relates to a knitting machine brake device with a retardance structure. The knitting machine brake device comprises a brake disc, expansion rings are mounted in the brake disc, friction plates are mounted between the outer walls of the expansion rings and the inner wall of the brake disc, the expansion rings comprise the first expansion ring and the second expansion ring symmetrical with the first expansion ring, one end of the first expansion ring and one end of the second expansion ring are rotatably connected to a machine frame, and a cam is mounted between the first expansion ring and the second expansion ring. The first expansion ring and the second expansion ring are connected through springs, and the cam makes tight contact with the inner wall of the first expansion ring and the inner wall of the second expansion ring; the first expansion ring is provided with a first retardance groove, and the second expansion ring is provided with a second retardance groove. The knitting machine brake device is simple in structure, the cam is arranged at the center of the expansion rings to symmetrically squeeze the symmetrical expansion rings, friction force between the friction plates and the brake disc is increased, brake time is reduced, and the brake effect is improved; the retardance grooves improve brake stability.
Description
Technical field
The present invention relates to field of textile machinery, particularly the brake apparatus of warping machines.
Background technology
Simultaneously warping machines is drawn from bobbin by the warp thread of certain radical, forms the warp thread piece of beautiful even, a parallel to each other arrangement, and be wound up into the equipment on warp beam or beam of a loom by the length specified and width parallel.If yarn breakage in the warping machines course of work, then must stop the operation of a machine immediately, it mainly relies on brake apparatus to realize.The brake apparatus of existing warping machines is generally internal expension ring formula friction catch, rely on the rubbing action between tensioner ring extrusion friction sheet and brake disc that cylinder is stopped during braking, its shortcoming existed is that the extruding force between friction plate and brake disc is not high enough, and its braking effect is not good, braking time is longer.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of knitting machine brake apparatus with speed bump, and it has, and structure is simple, the feature of good braking effect.
In order to solve the problem, the present invention adopts following scheme:
A kind of knitting machine brake apparatus with speed bump, comprise brake disc, in brake disc, tensioner ring is installed, between the outer wall of tensioner ring and the inwall of brake disc, friction plate is installed, tensioner ring comprises the first tensioner ring and the second tensioner ring that are arranged symmetrically with, one end of first tensioner ring and the second tensioner ring is rotationally connected with in frame respectively, is provided with cam between the first tensioner ring and the second tensioner ring; Be connected by spring between the first tensioner ring with the second tensioner ring, the inwall of cam and the first tensioner ring and the inwall close contact of the second tensioner ring; First tensioner ring has the first slow groove, the second tensioner ring has the second slow groove.
Technique effect of the present invention is:
Structure of the present invention is simple, arranges cam by the center between tensioner ring, carries out symmetry extruding, improve the frictional force between friction plate and brake disc, decrease braking time, improve braking effect the tensioner ring be arranged symmetrically with; The slow groove arranged improves the stationarity of braking.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, the present invention includes brake disc 1, in brake disc 1, tensioner ring is installed, between the outer wall of tensioner ring and the inwall of brake disc 1, friction plate 2 is installed, tensioner ring comprises the first tensioner ring 3 and the second tensioner ring 5 be arranged symmetrically with, one end of first tensioner ring 3 and one end of the second tensioner ring 5 are rotationally connected with in frame (not shown) respectively, are provided with cam 6 between the first tensioner ring 3 and the second tensioner ring 5; Be connected by spring 4 between the first tensioner ring 3 with the second tensioner ring 5, due to the elastic force effect of spring 4, the inwall of cam 6 and the first tensioner ring 3 and the inwall close contact of the second tensioner ring 5; First tensioner ring 3 has on the first slow groove 31, second tensioner ring 5 and there is the second slow groove 51.
