Abstract
The invention discloses mainly a cam control device of three angles, which comprises a motor, a substrate, a cam, a triangular plug and a spring. The motor is controlled automatically by a computer, and the cam in a profile of an Archimedes spiral line is installed on the rotating shaft of the motor and is sleeved in the through hole of the substrate. A groove for placing the triangular plug is arranged on the substrate, a bump for driving the triangular plug to move along the profile of the cam is arranged on the rear part of the triangular plug, and a spring hole for installing the spring is positioned at the bottom of the triangular plug for fixing the three angles. After the application of the scheme, the circular knitting machine obtains large variation of the fabric density and satisfies the demand of the market; meanwhile, the three angles can be changed automatically, no manual adjustment is needed and the production efficiency is improved.
Description
Technical field
The present invention relates to the knitting circular knitting machine density regulating apparatus, special relevant with a kind of cam control device of three angles.
Background technology
In original knitting circular knitting machine Auto-regulating System of Density of Heavy Medium mechanism, the variation of triangle is by manual adjustment fully, to reach the variation of knitting needle track.In so traditional mapping mode, must realize by readjusting triangle after shutting down, and the product variety that forms variation is single, uses inconvenience.So the resulting Density of original knitting circular knitting machine can not random multi-level variation.And market is big for variable density now, and the fabric demand that complexity is high day by day increases.Therefore, existing knitting circular knitting machine Auto-regulating System of Density of Heavy Medium structure must be done suitable improvement, thereby satisfies the existing market demand.
Given this, the inventor works out a kind of cam control device of three angles, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of cam control device of three angles, the Density that obtains is changed greatly, and do not need shutdown adjustment to realize that triangle changes, rely on automation control, mode of operation is simple.
Cam control device of three angles comprises motor, pedestal, cam, triangular plug and spring; Motor is subjected to computer controlled automatic; Profile is that the cam of spiral of Archimedes is installed on the motor output shaft, and is set in the through hole of pedestal; Also offer the groove of placing for triangular plug on the pedestal; The rear portion of triangular plug has the projection that the drive triangular plug moves along cam contour; The bottom that is used for fixing the triangular plug of triangle has the spring eye that the ammunition feed spring is installed.
The projection outside of described triangular plug is equipped with clutch shaft bearing, drives triangular plug by clutch shaft bearing and moves along cam contour, makes triangular plug move easily, also effectively protects projection and cam not easy to wear.
Described cam outside is with second bearing 8, is installed in by second bearing in the through hole of pedestal.
After adopting such scheme, motor is subjected to computer control, can carry out work automatically.Triangular plug is taken exercises along spiral of Archimedes, thereby it is various to make that triangle changes, and the Density that knitting circular knitting machine obtains changes greatly, and the complexity height can satisfy the demand in market, improves Enterprises'Competitiveness.Simultaneously, adopt this mode, the variation of triangle is not readjusted after not needing to shut down by hand, has improved the efficient of producing, and is easy and simple to handle.
Description of drawings
Fig. 1 is the generalized section of preferred embodiment of the present invention;
Fig. 2 is the enlarged drawing of cam of the present invention.
The specific embodiment
As shown in Figure 1, be preferred embodiment of the present invention, cam control device of three angles comprises motor 1, pedestal 2, cam 3, triangular plug 4 and spring 5.
Motor 1 is subjected to the computer control (not shown) of knitting circular knitting machine, and motor 1 can be common electric machine, also can be servomotor.Cam 3 is installed in the rotating shaft 10 of motor 1, and is set in the through hole 20 of pedestal 2.Cam 3 integral body are a column runner, and its structure is referring to Fig. 2, and front 30 profiles of cam 3 are spiral of Archimedes.
In the present embodiment, flexible, light in order to make that cam 3 rotates in through hole 20, be with second bearing 8 in the outside of cam 3, cam 3 is not only stable but also flexible, light when rotating like this.
Have groove 21 on the pedestal 2, groove 21 is placed for triangular plug 4.Groove 21 is communicated with through hole 20, during installation, and the front of the rear alignment cam 3 of triangular plug 4.
Be fixed with triangle 7 on the triangular plug 4, its fixed form is the common technology of this area, does not do here and gives unnecessary details.
There is a projection 40 at the rear portion of triangular plug 4, is with clutch shaft bearing 6 in the present embodiment on the projection 40, is fitted on the cam 3, makes projection 40 to rotate along the profile of cam 3, also moves up and down in groove 21 thereby drive whole triangular plug 4.Thereby reach the purpose of regulating Density.Simultaneously, clutch shaft bearing 6 makes projection 40 move easily along cam 3 profiles, also effectively protects projection 40 and cam 3 not easy to wear.
Spring eye 41 is also opened in the bottom of triangular plug 4, and spring 5 is inserted in the spring eye 41, and is fixed in groove 21 and the spring eye 41.So just, can be so that triangular plug 4 returns back to original position.
When the present invention works, the rotating shaft 10 of motor 1 is rotated, and the cam 3 above making also rotates thereupon, triangular plug 4 since projection 40 take and put on cam 3, rotate with cam 3 triangular plug 4 is taken exercises along spiral of Archimedes, do variation thereby drive the triangle 7 that is installed on the triangular plug 4.During triangular plug 4 motion, by the restoring force of spring 5, triangular plug 4 motion that can go round and begin again.
It is many that Density that such knitting circular knitting machine obtains changes level, and the complexity height just in time can satisfy on the market the demand of high-quality fabric, has greatly improved Enterprises'Competitiveness.
The variation of triangle does not simultaneously need manual adjustment, has saved the manpower work greatly, enhances productivity.
