The quick attach structure of top comb on a kind of combing machine
Technical field:
The present invention relates to the technical field of combing machine, more specifically to the quick attach structure of top comb on a kind of combing machine.
Background technology:
Combing machine, realizes the machinery that combing is used in spinning process.The Main Function of combing machine is: get rid of comparatively staple fibre, removes the kink grain (cotton knot, card nailing neps, grass bits, cocoon skin etc.) in fiber, fiber is stretched further, parallel, finally makes the more uniform yarn of thickness.Current combing machine has the parts such as cylinder, top comb to form, top comb forms installing hole, top comb is bolted connection in the frame of combing machine, and the card wire Chang Rongyi in top comb goes wrong, need safeguard carrying out replacing, thus top comb will be pulled down, then need loose bolt, and need again tight bolt after having keeped in repair, remove and install and comparatively bother.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides the quick attach structure of top comb on a kind of combing machine, and it facilitates top comb to remove and install, thus facilitates the repair and replacement of card wire in top comb.
Technology solution of the present invention is as follows:
The quick attach structure of top comb on a kind of combing machine, comprise frame and the top pecten of combing machine, top pecten forms the installing hole that some kidney-shapeds are poroid, the frame of combing machine is fixed with the boss of several and top pecten installing hole same shape, boss forms pillar, the top end face of pillar forms fulcrum, the outer wall of fulcrum upper end and the outer wall of a side form horizontal grooving and vertical grooving respectively, arc transition portion is formed between horizontal grooving and vertical grooving, described fulcrum is provided with the blend stop with boss same shape, blend stop forms the jack of D type, fulcrum is plugged in the jack of blend stop, linear pattern inwall in jack is pressed against on the outer wall at the vertical grooving place of fulcrum, the top of fulcrum is fixed with block, block is resisted against on blend stop, described pillar forms torsion spring, one end of torsion spring is fixed on boss, the other end is fixed on blend stop.
The diameter of described fulcrum is less than the diameter of pillar, and the length of fulcrum equals the thickness of blend stop, the length of pillar and the height of boss and the thickness that equals top pecten.
On described fulcrum, horizontal grooving equals the centre-to-centre spacing of vertical grooving to fulcrum center to the centre-to-centre spacing at fulcrum center, and between vertical grooving and horizontal grooving, the arc radius in arc transition portion equals the centre-to-centre spacing of vertical grooving to fulcrum center.
Described boss and the seamed edge of blend stop all form chamfering.
Beneficial effect of the present invention is:
The bolt that it has abandoned top comb traditional is fixedly connected with mode, adopts novel syndeton, thus the installing/dismounting of top comb is comparatively convenient, indirectly facilitates the repair and replacement of card wire in top comb.

Detailed description of the invention:
Embodiment: see shown in Fig. 1 to 4, the quick attach structure of top comb on a kind of combing machine, comprise frame and the top pecten 1 of combing machine, top pecten 1 forms the poroid installing hole of some kidney-shapeds 11, the frame of combing machine is fixed with the boss 2 of several and top pecten 1 installing hole 11 same shape, boss 2 forms pillar 21, the top end face of pillar 21 forms fulcrum 22, the outer wall of fulcrum 22 upper end and the outer wall of a side form horizontal grooving 221 and vertical grooving 222 respectively, arc transition portion 223 is formed between horizontal grooving 221 and vertical grooving 222, described fulcrum 22 is provided with the blend stop 3 with boss 2 same shape, blend stop 3 forms the jack 31 of D type, fulcrum 22 is plugged in the jack 31 of blend stop 3, linear pattern inwall in jack 31 is pressed against on the outer wall at vertical grooving 222 place of fulcrum 22, the top of fulcrum 22 is fixed with block 4, block 4 is resisted against on blend stop 3, described pillar 21 forms torsion spring 5, one end of torsion spring 5 is fixed on boss 2, the other end is fixed on blend stop 3.
The diameter of described fulcrum 22 is less than the diameter of pillar 21, and the length of fulcrum 22 equals the thickness of blend stop 3, the length of pillar 21 and the height of boss 2 and the thickness that equals top pecten 1.
On described fulcrum 22, the centre-to-centre spacing at horizontal grooving 221 to fulcrum 22 center equals the centre-to-centre spacing at vertical grooving 222 to fulcrum 22 center, and between vertical grooving 222 and horizontal grooving 221, the arc radius in arc transition portion 223 equals the centre-to-centre spacing at vertical grooving 222 to fulcrum 22 center.
Described boss 2 and the seamed edge of blend stop 3 all form chamfering.
Operation principle: when the present invention dismantles top pecten 1, only have and upwards rotate blend stop 3, time blend stop 3 overlap with the boss 2 in frame, thus just top pecten 1 can be pulled out taking-up, and when top pecten 1 is installed, first blend stop 3 is overlapped with the boss 2 in frame, top pecten 1 is put into frame convex platform 2, then unclamp blend stop 3, blend stop 3 rotates under the active force of torsion spring 5, and spacing top pecten 1 shifts out; Its boss 2 pairs of top pectens 1 have positioning action, and on fulcrum 22 structure of uniqueness and blend stop 3, the jack of D type matches, and can limit blend stop 3 and rotate within the scope of 45 °.
