Description

The selvedge scissors mechanism of rapier loom

Technical field

The utility model relates to a kind of cloth processing unit (plant), and more particularly, it relates to a kind of selvedge scissors mechanism of rapier loom.

Background technology

Rapier loom is a kind of loom comparatively general in textile machine, its can warp thread and weft yarn require interweave and form fabric according to Fabric Design. In the time weaving cotton cloth with rapier loom, need to install the cutting mechanism for shearing cloth.

Documents CN200820082657.7 discloses a kind of movable scissors device for rapier loom, and this movable scissors device that is used for rapier loom has can effectively eliminate parallel slitter edge, the advantage avoiding waste.

In process of production, because selvedge scissors mechanism is as the auxiliary body of cloth processing, need to match with the pace of cloth to the shear rate of cloth. When the pace of cloth can be accelerated, the shear rate of selvedge scissors mechanism more can cause cloth to be deposited in place of selvedge scissors mechanism, affects the operation of selvedge scissors mechanism. In the time that the pace of cloth slows down, and the shear rate of selvedge scissors mechanism is very fast, can cause selvedge scissors mechanism in the time starting to shear, and does not but have the situation that cloth need to be sheared to occur, causes shear mechanism to occur unnecessary wearing and tearing.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of selvedge scissors mechanism of rapier loom. The selvedge scissors mechanism of this rapier loom is by the height of eccentric adjustment cam, thereby in the time that eccentric cam rotates identical angle, the angle that can make movable blades rotate can change, cause each sheared length to change, thereby change the shear rate of cloth to adapt to the progressive speed of cloth.

For achieving the above object, the utility model provides following technical scheme:

A kind of selvedge scissors mechanism of rapier loom, comprise knife rest, be located at the rotating shaft on knife rest, with rotating shaft socket and with the eccentric cam of rotating shaft interlock, be located at the fixed blade of knife rest, be articulated in the movable blades on knife rest, the roller being connected with movable blades, two ends connect respectively the elastic component of movable blades and knife rest, described roller and eccentric cam butt, described knife rest is provided with the first groove of vertical setting, described rotating shaft also can slide up and down along the first groove through the first groove, the first fixture of fixed rotating shaft after described knife rest is provided with and slides along the first groove for rotating shaft.

By adopting technique scheme, utilize rotating shaft to slide along the first groove, and utilize the position after the first fixture fixed rotating shaft slides, thereby realize the adjusting of countershaft height. And eccentric cam and rotating shaft socket, thereby in the time that rotating shaft moves up and down, rotating shaft meeting drives eccentric cam to move up and down, the movement of the contact position that the moving up and down of eccentric cam means eccentric cam and roller, and in the time that eccentric cam rotates identical angle, the angle that movable blades rotates can change, and causes sheared length to change, and changes the shear rate of cloth to adapt to the progressive speed of cloth.

The utility model is further set to: described the first fixture comprise with the bearing of rotating shaft socket, be located at the upper surface of knife rest and the first through hole of being communicated with the first groove, through the first connecting axle being connected with bearing after the first through hole, be located at the upper surface of knife rest and with the first axle sleeve of the first connecting axle socket, pass the first screwed hole of arranging on the first axle sleeve and the first set bolt of the first connecting axle butt.

By adopting technique scheme, the first connecting axle is through the first through hole that is located at knife rest upper surface, and therefore the first connecting axle can axially move along the first through hole. And the first connecting axle is connected with bearing, so bearing moves up and down under the drive of the first connecting axle. Utilize first set bolt butt the first connecting axle being spirally connected with the first axle sleeve, thus realize the first connecting axle is moved up and down after position fixing. And the first connecting axle and bearing interlock, so the position after bearing moves up and down is also fixed. And rotating shaft is and bearing socket, therefore realize in rotating shaft and can after the first groove slides, be fixed, can not affect the normal rotation of rotating shaft simultaneously.

The utility model is further set to: on described bearing, be provided with contiguous block, described the first connecting axle and contiguous block are spirally connected.

By adopting technique scheme, contiguous block is set on bearing, utilize contiguous block and the first connecting axle to be spirally connected, thus realize between the first connecting axle and bearing detachably, facilitate the later stage to work as when bearing is damaged and be convenient for changing, reduce maintenance cost.

The utility model is further set to: on described eccentric cam, be provided with groove, the width of described groove equates with the width of roller.

By adopting technique scheme, because the width of the width of groove and roller equates, so groove plays and all the time roller portion is stuck in to the effect in groove in roller and eccentric cam contact process, thereby can be all the time and the butt of roller the effect that drives movable blades to rotate at vibration processes eccentric cam, the situation generation of avoiding eccentric cam and roller that skew occurs and can not driving movable blades to rotate.

The utility model is further set to: on described knife rest, be provided with fixed block, the sliding axle that described fixed block is provided with the second groove of vertical setting and slides up and down along the second groove, one end of described elastic component is connected with sliding axle, the other end is connected with movable blades, the second fixture of fixing sliding axle after described fixed block is provided with and slides along the second groove for sliding axle.

By adopting technique scheme, utilize sliding axle to slide along the second groove, and utilize the position after the fixing sliding axle of the second fixture slides, thereby realize the adjusting to sliding axle height. And elastic component one end is connected with sliding axle, the other end is connected with movable blades, thereby in the time that sliding axle moves up and down, the initial deformation state of elastic component is changed, thereby the resistance that when movable blades is rotated under eccentric cam drives, elastic component produces regulates, the resistance of elastic component part can affect the pressure of movable blades to cloth, thereby have influence on, the shearing force of cloth is regulated, thereby further regulates the shear rate to cloth.

The utility model is further set to: described the second fixture comprise the second through hole of being located at fixed block upper surface and be communicated with the second groove, through the second connecting axle being connected with sliding axle after the second through hole, be located at the upper surface of fixed block and with the second axle sleeve of the second connecting axle socket, pass the second screwed hole of arranging on the second axle sleeve and the second set bolt of the second connecting axle butt.

By adopting technique scheme, the second connecting axle is through the second through hole that is located at fixed block upper surface, and therefore the second connecting axle can axially move along the second through hole. And the second connecting axle is connected with sliding axle, so sliding axle moves up and down under the drive of the second connecting axle. Utilize second set bolt butt the second connecting axle being spirally connected with the second axle sleeve, thus realize the second connecting axle is moved up and down after position fixing. And the second connecting axle and sliding axle interlock, so the position after sliding axle moves up and down is also fixed.
