A kind of Fast Installation structure of top comb on combing machine
Technical field:
The present invention relates to the technical field of combing machine, more specifically to a kind of Fast Installation knot of top comb on combing machine
Structure.
Background technology:
Combing machine, realizes the machinery used by combing in spinning process.The Main Function of combing machine is:Exclude shorter fibre
Dimension, removes kink grain (cotton knot, card nailing neps, grass cuttings, callouses etc.) in fiber, fiber is further stretched, parallel, is finally made thick
Carefully than more uniform yarn.Current combing machine has the parts such as cylinder, top comb to constitute, and mounting hole is formed in top comb, and top comb is led to
Bolt is crossed to be fastenedly connected in the frame of combing machine, and the card wire Chang Rongyi in top comb goes wrong, and need to will carry out replacing maintenance,
So as to top comb be pulled down, then need to need tight bolt again after the completion of loose bolt, and maintenance, remove and install and more bother.
The content of the invention:
The purpose of the present invention and provides a kind of Fast Installation knot of top comb on combing machine aiming at the deficiency of prior art
Structure, it facilitates top comb to remove and install, so as to facilitate the repair and replacement of card wire in top comb.
Technology solution of the invention is as follows:
A kind of Fast Installation structure of top comb on combing machine, including combing machine frame and top pecten, on top pecten be molded
There is the poroid mounting hole of some kidney-shapeds, several are fixed with the frame of combing machine convex with top pecten mounting hole same shape
Platform, forms pillar on boss, form fulcrum on the top end face of pillar, on the outer wall of the outer wall of fulcrum upper end and a side point
Horizontal grooving and vertical grooving are not formed, and arc transition portion, described fulcrum are formed between horizontal grooving and vertical grooving
The blend stop with boss same shape is provided with, the jack of D types is formed on blend stop, fulcrum is plugged in the jack of blend stop, jack
Interior linear pattern inwall is pressed against on the outer wall at the vertical grooving of fulcrum, and the top of fulcrum is fixed with block, and block is resisted against gear
On bar;Form torsion spring on described pillar, one end of torsion spring is fixed on boss, the other end is fixed on blend stop.
Less than the diameter of pillar, the length of fulcrum is equal to the thickness of blend stop to the diameter of the fulcrum, the length of pillar with it is convex
Height and equal to top pecten the thickness of platform.
Horizontal grooving is equal to the centre-to-centre spacing of vertical grooving to fulcrum center to the centre-to-centre spacing at fulcrum center on the fulcrum, erects
The arc radius in arc transition portion are equal to the centre-to-centre spacing of vertical grooving to fulcrum center between vertical cut groove and horizontal grooving.
Chamfering is formed on described boss and the seamed edge of blend stop.
The beneficial effects of the present invention are:
It has abandoned the traditional bolt of top comb and has been fixedly connected mode, using new attachment structure, so that the installation of top comb
Dismounting is more convenient, and the repair and replacement of card wire in top comb are facilitated indirectly.

Specific embodiment:
Embodiment:As shown in Fig. 1 to 4, a kind of Fast Installation structure of top comb on combing machine, including combing machine frame and
Top pecten 1, forms the poroid mounting hole 11 of some kidney-shapeds on top pecten 1, several are fixed with the frame of combing machine with top
The boss 2 of the same shape of 1 mounting hole of pecten 11, forms pillar 21 on boss 2, fulcrum is formed on the top end face of pillar 21
22, horizontal grooving 221 and vertical grooving 222, horizontal cutting are formed respectively on the outer wall of the upper end of fulcrum 22 and the outer wall of a side
Arc transition portion 223 is formed between groove 221 and vertically grooving 222, described fulcrum 22 is provided with and the same shape of boss 2
Blend stop 3, forms the jack 31 of D types on blend stop 3, fulcrum 22 is plugged in the jack 31 of blend stop 3, in the linear pattern in jack 31
Wall pressure is leaned against on the outer wall at the vertical grooving 222 of fulcrum 22, and the top of fulcrum 22 is fixed with block 4, and block 4 is resisted against blend stop 3
On;Form torsion spring 5 on described pillar 21, one end of torsion spring 5 is fixed on boss 2, the other end is fixed on blend stop 3.
The diameter of the fulcrum 22 is less than the diameter of pillar 21, and the length of fulcrum 22 is equal to the thickness of blend stop 3, pillar 21
Height and equal to top pecten 1 the thickness of length and boss 2.
Horizontal grooving 221 to the centre-to-centre spacing at the center of fulcrum 22 is equal in vertical grooving 222 to fulcrum 22 on the fulcrum 22
The centre-to-centre spacing of the heart, the arc radius in arc transition portion 223 are equal to vertical grooving 222 between vertical grooving 222 and horizontal grooving 221
To the centre-to-centre spacing at the center of fulcrum 22.
Chamfering is formed on described boss 2 and the seamed edge of blend stop 3.
Operation principle:During present invention dismounting top pecten 1, be only rotated up blend stop 3, when blend stop 3 and frame on boss 2
Overlap, so that just top pecten 1 can be pulled out into taking-up, and when top pecten 1 is installed, first blend stop 3 overlap with the boss 2 in frame,
Top pecten 1 is put into frame convex platform 2, blend stop 3 is then unclamped, blend stop 3 is rotated under the active force of torsion spring 5, spacing top comb
Plate 1 is removed;Its boss 2 has positioning action to top pecten 1, and the jack of D types matches on the structure of fulcrum 22 of uniqueness and blend stop 3
Close, blend stop 3 can be limited and rotated in the range of 45 °.
