Abstract
The utility model belongs to the mechanism of a shedding device of weaving machine for withdrawing heald, and particularly relates to a mechanism of an active weaving machine for withdrawing heald with driving connecting rod provided on lower part. Comprising a shedding connecting rod, a group of right rocker arm devices, at least one group of left rocker arm devices, and a connecting rod, the utility model is characterized in that at least one group of auxiliary rocker arm devices of the connecting rod are arranged additionally between the left and right rocker arm devices. The auxiliary rocker arm device of the connecting rod comprises an auxiliary arm and a hinge base for the auxiliary rocker. The lower end of the auxiliary arm is hinged with the connecting rod and the upper end is hinged with the upper end of the hinge base for the auxiliary arm. Meanwhile, the lower end of the hinge base is fixed on the steel beam of the machine frame. The utility model prevents the connecting rod from bending or even breaking in the middle part due to excessive lengths. The mechanism enhances the structure performance of the connecting rod so as to make even the inner component forces inside the rod. The auxiliary rocker arm device provides good support to the connecting rod and guides the connecting rod to run smoothly at a high speed in order to meet the operation requirements of high speed weaving machines with various breadths.
Description
Technical field
The utility model belongs to returning of shedding device of weaving machine and combines mechanism, more particularly is that the active type connecting rod underneath type of shedding device of weaving machine goes back to comprehensive mechanism.
Background technology
On loom, to finish heald frame harness motion clocklike,, outside flat-bed machine, cam, dobbies and jacquard etc., also need the supporting comprehensive mechanism of going back to of various shedding motions that is fit to except being equipped with all kinds of shedding motions.Time comprehensive mechanism of shedding motion can be divided into passive type spring flowing heald mechanism and the active type connecting rod goes back to comprehensive mechanism.Passive type spring flowing heald mechanism utilizes the restoring force of the power of shedding motion and spring to realize the harness motion of heald frame; The active type connecting rod goes back to comprehensive mechanism and then utilizes the power of shedding motion to realize the harness motion of heald frame.The active type connecting rod returns the basic structure of comprehensive mechanism respectively by (all being example with the underneath type) shown in Fig. 1,2, shown in mechanism be used in multi-arm or cam opening device, according to the different loom case width of cloth and configuration modes, adopt the active type connecting rod underneath type of the conventional loom door width of cloth that Fig. 1 provides to return the active type connecting rod underneath type of combining the wide cut loom shown in mechanism and Fig. 2 respectively and return and combine mechanism.Know from Fig. 1 and Fig. 2,, go back to comprehensive mechanism so be referred to as underneath type because shedding device of weaving machine is configured in the below of loom.If shedding device of weaving machine is configured in the top of loom, so just be referred to as overhead type return mechanism.Because being the active type connecting rod underneath type that is suitable for the conventional door width of cloth, Fig. 1 goes back to comprehensive mechanism, so only adopt one group of left and right rocker arrangement 5,3, shedding motion is changed the harness motion of realizing opening arm 1 by self after the power input, opening arm 1 drives right rocker arrangement 3 by the opening connecting rod 2 with its binding, right rocker arrangement 3 and left rocker arrangement 5 achieve synchronous swing by being rigidly connected of long connecting rod 4, thereby make the upper and lower reposefully motion of heald frame 6 that links with left and right rocker arrangement 5,3, nationality is to realize the harness motion of loom; Because Fig. 2, therefore adopts one group of right rocker arrangement 3 and two groups of left side rocker arrangements 5 at the wide cut loom.Combine mechanism and directly apply to the loom rotating speed when 550n/min is following when the active type connecting rod underneath type of said structure returns, facts have proved that result of use is better.Yet the rotating speed of high-speed weaving machine is generally at 550-900n/min, owing to return the high speed reciprocating motion of combining mechanism at present, add the vibration of loom self, easily make connecting rod 4 produce chatter, the mechanical performance of connecting rod 4 is greatly reduced, and then cause connecting rod 4 in frequent motion back fatigue fracture at a high speed.According to the known opening theory of industry, the size of opening increases from 16 heald frames of first heald frame to the successively, and therefore, the amplitude of oscillation of corresponding last several connecting rods 4 increases, more easy fracture, even damage heald frame 6.If the anti-fracture strength of connecting rod 4 is improved, then by existing connecting rod material, to make treatment process and assembly technology all are the instructions for uses that can't satisfy high-speed weaving machine.
Summary of the invention
Task of the present utility model is will provide a kind of can guarantee that wearing and tearing can not appear in connecting rod and the active type connecting rod of using the high-speed weaving machine instructions for use of satisfying various wide cuts that ruptures goes back to comprehensive mechanism.
Task of the present utility model is finished like this, a kind of active type connecting rod underneath type returns combines mechanism, it comprises opening connecting rod 2, one group of right rocker arrangement 3 and at least one group of left side rocker arrangement 5 and connecting rod 4, the end that opening connects pavilion 2 is connected with the opening arm 1 of shedding device of weaving machine, the lower end of the other end and right rocker arrangement 3 is hinged, and, the lower end of right rocker arrangement 3 also links with connecting rod 4, the upper end of right rocker arrangement 3 is connected with heald frame 6, the upper end of left side rocker arrangement 5 is connected with heald frame 6, lower end and connecting rod 4 link, characteristics are: on a described left side, right rocker arrangement 5, have additional at least one connecting rod auxiliary rocker arm device 7 between 3, this connecting rod auxiliary rocker arm device 7 comprises a sub-arm 71 and sub-arm hinged seat 72, the lower end of sub-arm 71 is hinged on the connecting rod 4, and the upper end of upper end and sub-arm hinged seat 72 is hinged, and the lower end of sub-arm hinge joint seat 72 is fixed on the frame girder steel 8 of loom.
The quantity of connecting rod auxiliary rocker arm device 7 described in the utility model lacks one than the summation of left and right rocker arrangement 3,5.
The lower end of sub-arm 71 described in the utility model is hinged with connecting rod 4 by means of a leg 711, and the upper end is hinged by means of an arm hole 712 and sub-arm hinge joint seat 72.
The shape U-shaped in general of leg 711 described in the utility model, the lower end of sub-arm 71 is contained in the cavity volume of this U-shaped, and is linked by bearing pin.
The bottom of sub-arm hinged seat 72 described in the utility model has extended a pair of fixedly ear 721 to two sides, fixedly ear 721 fixes with the frame girder steel 8 of loom, the upper end of sub-arm hinged seat 72 has extended hinge post 722 to a side of sub-arm 71, and hinge post 722 is stretched in the arm hole 712.
Be concaved with jump ring groove 7221 on the hinge post 722 described in the utility model.
The utility model is owing to set up the connecting rod auxiliary rocker arm device 7 of at least one dead axle swinging structure between left and right rocker arrangement 5,3, locate oscillation center with connecting rod auxiliary rocker arm device 7, thereby can avoid causing that because of connecting rod 4 is too tediously long connecting rod 4 middle bent are out of shape and even fracture, improve the structural behaviour at connecting rod 4 middle parts simultaneously, play the component effect of homogenizing connecting rod 4 inside; Connecting rod auxiliary rocker arm device 7 is support link 4 and guiding connecting rod 4 motion freely at a high speed well, and nationality is to satisfy the high-speed weaving machine instructions for use of various wide cuts.
