The embodiment of the utility model is written in a progressive mode.

As shown in fig. 1-4, the weft laying trolley comprises a first yarn pressing plate 1 and a hook 2, wherein two parallel clamping surfaces 3 are respectively arranged on the first yarn pressing plate 1 and the hook 2, and at least one of the first yarn pressing plate 1 and the hook 2 moves perpendicular to the clamping surfaces 3; be provided with the passageway 4 that supplies the yarn to run through between first pressure yarn board 1 and the couple 2 the two, when first pressure yarn board 1 and couple 2 kept away from each other, passageway 4 is provided with the uncovered 41 that supplies the yarn to get into in one side of shop's latitude direction, and uncovered 41 department is provided with card and structure 5, and card and structure 5 press from both sides tight back at two clamp surfaces 3 to the yarn clamp, close uncovered 41.

In this embodiment, in the process of increasing the length of the yarn clamping portion, the length of the hook 2 is increased, and due to the arrangement of the opening 41, a weak part of the structure exists after the whole channel 4 is closed, so that the yarn clamping force at the position is very easy to form a difference with other positions in the yarn clamping process, in order to overcome the problem that the yarn tension is unstable due to the difference, the clamp and the structure 5 are arranged in this embodiment, and therefore in the yarn clamping process, the stability of the clamping force at each position after the whole channel 4 is closed can be ensured.

Preferably, the clamp and structure 5 comprises an air cylinder 52 and a pull buckle 53, the air cylinder 52 is fixedly connected with the first yarn pressing plate 1 or the hook 2, the pull buckle 53 is fixed at the end part of the piston rod of the air cylinder 52, and one of the first yarn pressing plate 1 and the hook 2 which is not connected with the air cylinder 52 is provided with a clamping groove 54 for the pull buckle 53 to clamp. In the preferred embodiment, as shown in fig. 5 and 6, the clamp and structure 5 is realized by the cooperation of the air cylinder 52 and the pull buckle 53, when the cooperation of the pull buckle 53 and the clamping groove 54 needs to be released, the piston rod of the air cylinder 52 extends out, so that the pull buckle 53 is removed from the clamping groove 54, the first yarn pressing plate 1 and the hook 2 can be relatively separated, when the cooperation of the pull buckle 53 and the clamping groove 54 needs to be released, the piston rod of the air cylinder 52 retracts, so that the pull buckle 53 is clamped into the clamping groove 54, and the first yarn pressing plate 1 and the hook 2 are locked at the clamping position for yarn.

In practice, the air cylinder 52 is preferably fixedly connected to the first yarn pressing plate 1, and the first yarn pressing plate 1 moves relative to the fixed hook 2. In the preferred embodiment, the hook 2 is fixed so that a clamping reference surface is obtained during the yarn clamping process, i.e. the yarn is finally clamped on the clamping surface 3 which is fixed, in this way, the yarn clamping process is controlled more easily, the extension and retraction of the piston rod of the air cylinder 52 can control the interference problem with the hook 2, and the force required for locking the fastener 53 and the clamping groove 54 is provided.

As a preference of the above embodiment, as shown in fig. 7, the hook 2 is provided with a convex portion 21 at the opening 41, the convex portion 21 forms a boundary of the channel 4, the end of the convex portion 21 forms a convex edge 22 into the channel 4, the convex edge 22 and the convex portion 21 are arranged at a right angle, and the right angle is used as a clamping groove 54. Through the setting of bulge 21 and protruding edge 22, for drawing buckle 53 provides bigger activity space, the effectual interference condition of avoiding in the work, can guarantee the card and validity through the draw-in groove 54 that becomes the right angle setting, and the shaping is simple.

Preferably, as the above embodiment, the edge 22a of the end face edge of the protruding edge 22 opposite to the first yarn pressing plate 1, which is parallel to the clipping width of the pull buckle 53, is provided with a corner guiding structure to form a first corner guiding surface, so as to avoid collision with the pull buckle 53. For the same purpose, the tab 53 is provided with a second angle guiding surface parallel to the first angle guiding surface.

In order to facilitate processing and installation adjustment, an installation plate body 51 is arranged between the air cylinder 52 and the first yarn pressing plate 1, so that the plate body area of the first yarn pressing plate 1 is reduced, pre-installation with the air cylinder 52 can be realized through the installation of the installation plate body 51, and angle adjustment of the air cylinder 52 is facilitated.

As a preference of the above embodiment, the first yarn pressing plate 1 is provided with at least two force bearing points 11 along the weft laying direction, so that the clamping force of the whole first yarn pressing plate 1 on the yarns is more stable. Wherein the force bearing point 11 is connected with the end of the piston rod of the second cylinder 12.
