Abstract
The invention relates to a warping machine brake provided with an elastic press rod. The brake comprises a brake disc, expansion rings are installed inside the brake disc, and friction plates are installed 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 which are symmetrically arranged. One end of the first expansion ring and one end of the second expansion ring are both rotatably connected with a rack, a cam is installed between the first expansion ring and the second expansion ring, and the two ends of the cam are connected with the press rod through springs respectively. The first expansion ring is connected with the second expansion ring through a spring, and the cam and an auxiliary press wheel of the cam make tight contact with the inner wall of the first expansion ring and the inner wall of the second expansion ring. The brake is simple in structure, the cam and the elastic press rod are arranged in the center of the space between the expansion rings to perform symmetric extrusion on the expansion rings, and therefore the friction force between the friction plates and the brake disc and the brake effect are improved.
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 brake of band elastic pressure bar of warping machines, 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 brake of band elastic pressure bar of warping machines, 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, and the two ends of cam connect depression bar by spring respectively; Be connected by spring between the first tensioner ring with the second tensioner ring, the inwall of cam and auxiliary pinch roller and the first tensioner ring and the inwall close contact of the second tensioner ring.
Technique effect of the present invention is:
Structure of the present invention is simple, arranges cam and elastic pressure bar and carries out symmetry to tensioner ring and extrude, improve the frictional force between friction plate and brake disc and braking effect by the center between tensioner ring.
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, and be provided with cam 6 between the first tensioner ring 3 and the second tensioner ring 5, the two ends of cam 6 connect depression bar 7 by spring 8 respectively; 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 auxiliary pinch roller 7 of cam 6 machine respectively with the inwall of the first tensioner ring 3 and the inwall close contact of the second tensioner ring 5.
When the present invention works, by rotating cam 6, first tensioner ring 3 and the second tensioner ring 5 are rotated around the twisted axis be connected in frame (not shown) simultaneously, and cam 6 and depression bar 7 thereof outwards extrusion friction sheet 2, the rubbing action produced between friction plate 2 and brake disc 1 makes cylinder stop motion.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
