The form of the yarn clamping sheet 1 can be set in various ways according to different use requirements, and the purpose of supporting the weft yarn can be achieved. The jacking force piece 3 can be provided with various forms corresponding to different forms of the yarn clamping piece 1, as long as the force can be transmitted to the yarn clamping piece 1, and the angle of the yarn clamping piece 1 can be adjusted up and down. As shown in fig. 6, the yarn clamping piece 1 comprises an elastic clamping piece 11, a yarn supporting section 12 and a yarn clamping inclined plane 13, one end of the elastic clamping piece 11 is provided with a first mounting hole 14 connected with a weft yarn clamping seat, the other end of the elastic clamping piece 11 is an upward inclined yarn supporting section 12, and the free end of the yarn supporting section 12 is provided with a downward inclined yarn clamping inclined plane 13. The jacking piece 3 is step-shaped, one end of the jacking piece 3 is provided with a second mounting hole 24 connected with the weft yarn clamping seat 4, the other end of the jacking piece is a jacking section 32, the middle part of the jacking piece 3 is a force generation section 31, and the adjusting piece is arranged below the force generation section. The upward movement of the adjustment element transmits the force to the force-generating section 31 and the force-pushing section 32, said force-pushing section 32 finally transmitting the force to the gripper tongue 1. The upward movement of the adjusting piece is supported below the force generation section, the adjusting piece continues to move upward to drive the force generation section to move upward, the upward movement of the force generation must simultaneously drive the upward movement of the jacking piece, and the upward movement of the jacking piece transfers force to the yarn supporting section of the yarn clamping piece, so that the upward inclination of the yarn supporting section of the yarn clamping piece is adjusted.
As shown in figure 4, the middle height of the yarn clamping piece 1 is higher than the weft yarn path formed by the weft selecting finger and the yarn blocking bracket, the inclined surface at the end part of the yarn clamping piece inclines downwards to prop against the inner arc surface of the yarn clamping and guiding bracket 2, and the weft yarn enters the contact surface and is pressed tightly, so that the gripper head increases the holding force on the weft yarn.
As shown in fig. 7, the yarn clamping sheet 1 and the jacking force sheet 3 can be in another form, the elastic clamping sheet of the yarn clamping sheet 1 is a horizontal clamping sheet, one end of the horizontal clamping sheet is connected with the weft yarn clamping seat through a fastening bolt, the other end of the horizontal clamping sheet is provided with a downward inclined yarn clamping slope, and the inclined yarn clamping slope is in contact with the arc surface of the yarn clamping and guiding frame. The top force piece is Z-shaped, the force generation section of the top force piece is in a horizontal plate shape, and the force generation section is directly contacted with the yarn clamping piece under the driving of the adjusting piece.

The function of clamping the weft yarn is realized by the contact of the arc surface 23 and the yarn clamping inclined surface 13 of the yarn clamping sheet 1. The inclined plane structure is that weft yarns are sequentially improved when the reed punches the weft yarns into a cloth fell, so that collision of the movable scissors is avoided; the weft yarn clamping seat 4 can slide in the long groove of the guide rail.
As shown in fig. 1, the adjusting member is an adjusting screw 5, a screw rod of the adjusting screw 5 is in threaded connection with the weft yarn clamping seat 4, and the inclination adjustment of the yarn clamping piece 1 is controlled by the up-and-down movement of the adjusting screw 5.
The yarn clamping and guiding frame 2 is in arc contact with the yarn clamping piece 1, the weft yarn clamping stress section is a small section, the weft yarn can be prevented from being stressed for a long time, the yarn clamping piece is made of elastic materials, the rapier head drives the weft yarn to move forward, the impact force can also drive the weft yarn out of the clamping opening, and the weft yarn is prevented from being stressed for a long time; the outer end of the yarn clamping and guiding frame is an inclined plane, and when the weft yarns are driven into a cloth fell by the reed, the weft yarns can be lifted in a sliding manner, so that the weft yarns are prevented from contacting with parts such as the head part of a scissors, and the yarns are prevented from being damaged.
The weft selecting finger drives the weft to fall down, the rapier head starts to move, the middle area of the elastic yarn supporting and clamping piece is higher, the yarn can form a parabola shape, the yarn is preliminarily brought into a rapier head yarn clamping opening by matching with the shape of the rapier head yarn clamping opening, the rapier head drives the weft to move towards the inner side of a weaving opening, when the weft enters a clamping opening of the clamping mechanism, the weft is clamped by the yarn clamping piece and a contact surface of the yarn clamping frame, the rapier head continues to move towards the weaving opening, but the clamping mechanism clamps the yarn for a short time and leads the instantaneous tension of the yarn to reach a certain value, and the weft continues to move towards the inner side of the rapier head yarn clamping opening, so that the coating degree and pressing force of the yarn clamping opening on the yarn are higher. Particularly for bright silk yarns, the surface is smooth, if the clamping force of the rapier head on the yarns is insufficient, the rapier head can easily slide out from the inside, so that the handing-over is unstable, and the mechanism can be used for actively avoiding the problems.
The rapier head is withdrawn from the weaving opening, when the reed is beaten up, the weft yarn 8 moves to the front side of the weaving opening along with the rapier head, if the position of the weft yarn scissors or the weft yarn guide sheet is not good, the weft yarn scissors or the weft yarn guide sheet easily collide with the weft yarn, and the weft yarn with small tension can be abraded sometimes. The outer end of the head of the yarn guide frame is designed into a smooth inclined plane, so that weft yarns can be gradually lifted in the beating-up stage and then enter the weft yarn holding mechanism. In the face of different weft counts, the required clamping force is different, and the adjusting screw can be rotated, so that the jacking force piece adjusts the jacking force of the yarn supporting and clamping piece to adjust the clamping force of the yarn clamping piece on the weft.
The utility model is used for the leading-in rapier head mechanism of woof centre gripping can instantaneously improve woof tension, and favourable rapier head is raised when can making the reed squeeze into the woof again to the woof centre gripping, does not collide other structures, and the power improves loom efficiency, supplementary reduction weaving cost.
The foregoing is merely illustrative of some of the principles of the present invention and the description is not intended to limit the invention to the specific constructions and applications shown, so that all modifications and equivalents that may be utilized are within the scope of the invention.
Other technical features than those described in the specification are known to those skilled in the art.
