Description

The Scissors box that is used for Rapier looms

Technical field

The utility model relates to a kind of Scissors box that is used for Rapier looms.

Background technology

The mature equipment that Rapier looms belongs to simple in structure in textile industry, adaptability is stronger is quoted in the present textile industry widely.The operation principle of Rapier looms is that parallel is in the same place with warp knitting by a kind of line sending or termination, can produce the parallel fabian of certain size length at the Rapier looms two ends, at parallel fabian place for do not allow parallel because itself elasticity and bounce back, be provided with in addition through the sideline, play the effect that clamps parallel, thereby avoid the generation of substandard products cloth, still the clamping action in this method has all become waste through the sideline with the parallel fabian.

In order to eliminate the parallel fabian, Chinese patent has been announced the movable scissors device that is used for Rapier looms No. 200820082657.7, comprise scissors, lower scissors and fixed mount, also include casing and wabbler mechanism, cam drive is installed on casing, on this cam drive, be provided with a cam, last scissors and lower scissors are by last, the lower scissors frame is installed on the rocking carrier, rocking carrier is rotating to be installed in the fixed mount, on this fixed mount, drive link is installed, one side of drive link is a cam, and wabbler mechanism includes rocking arm and extension spring, and extension spring one end is fixed on the rocking arm, the other end is fixed on the rocking carrier, on rocking carrier, also be provided with the retraction spring that is connected with casing, the rear end bifurcated of last shear shank, wherein the upper end of bifurcated contacts with drive link, the end of lower end and lower scissors frame is gear-like and is meshing with each other, last, be provided with stage clip between the lower scissors frame.

But, this movable scissors apparatus structure complexity that is used for Rapier looms, and rubbing of upper and lower shear shank be gear-like, be meshing with each other, and causes part to make the shortcoming complicated, that cost is high; And the scissors cutting edge accurately meshed and parallel could be cut off about this scissors apparatus needed, and caused the demanding shortcoming of installation accuracy of part; And the cutter of traditional scissors apparatus generally adopts hard alloy cutter, and blade is easy to wear, and the service life of cutter is short, and is with high costs.

Summary of the invention

For overcoming the above-mentioned shortcoming of prior art, it is a kind of simple in structure that the utility model provides, and installation accuracy requires low, the with low cost Scissors box that is used for Rapier looms.

Be used for the Scissors box of Rapier looms, comprise frame, described frame is provided with cam mechanism and cutting mechanism, and described cutting mechanism comprises blade and the rocking arm that is connected with described cam; It is characterized in that: described rocking arm comprises with described cam and is connected first rocking bar, the rear end of the close described cam of described first rocking bar is connected with described frame by back-moving spring, the front end of described first rocking bar and described frame are hinged, second rocking bar that the front end of described first rocking bar is provided with is outward extending, be used to install blade; Be fixed with the chopping board that cooperates with described blade on the described frame.

Further, what the position corresponding with described blade was provided with location parallel to be sheared leads the latitude hook, and the described latitude hook of leading is provided with the step surface of placing parallel, and described chopping board is fixed on the described step surface.

Further, described second rocking bar is connected with described blade by blade holder, and described blade holder is connected with described second rocking bar by first trip bolt, and described blade holder is provided with first chute that cooperates with described first trip bolt.

Further, the described latitude hook of leading is connected with described frame by described second trip bolt, and the described latitude hook of leading is provided with second chute that cooperates with described second trip bolt.

Further, described blade is a disposable blade.

Further, described first rocking bar is connected with described cam by roller.

Technical conceive of the present utility model is: when shearing parallel, cam is a rise, promotes first rocking bar and swings forward, drives second rocking bar to lower swing, thereby blade is depressed to chopping board, and parallel is cut off; After parallel was cut off, cam was backhaul, and first rocking bar is swung backward under the effect of back-moving spring and resetted, and second rocking bar upwards lifts, and blade leaves chopping board.

The utlity model has simple in structurely, installation accuracy requires low, with low cost advantage.

The specific embodiment

With reference to accompanying drawing, further specify the utility model:

The Scissors box that is used for Rapier looms comprises frame 1, and described frame 1 is provided with cam mechanism and cutting mechanism 3, and described cutting mechanism comprises blade 31 and the rocking arm that is connected with described cam 2; Described rocking arm comprises with described cam 2 and is connected first rocking bar 321, the rear end of the close described cam 2 of described first rocking bar 321 is connected with described frame 1 by back-moving spring 33, the front end of described first rocking bar 321 and described frame 1 are hinged, second rocking bar 322 that the front end of described first rocking bar 321 is provided with is outward extending, be used to install blade 31; Be fixed with the chopping board 34 that cooperates with described blade 31 on the described frame 1.

What the position corresponding with described blade 31 was provided with location parallel to be sheared leads latitude hook 35, and the described latitude hook 35 of leading is provided with the step surface 351 of placing parallel, and described chopping board 34 is fixed on the described step surface 351.

Described second rocking bar 322 is connected with described blade 31 by blade holder 36, described blade holder 36 is connected with described second rocking bar 322 by first trip bolt 361, and described blade holder 36 is provided with first chute 362 that cooperates with described first trip bolt 361.

The described latitude hook 35 of leading is connected with described frame 1 by described second trip bolt 352, and the described latitude hook 35 of leading is provided with second chute 353 that cooperates with described second trip bolt 352.
