The technical solution of the present invention will be described in detail with specific examples. The following specific embodiments may be optionally combined with or replaced by each other according to practical situations, and the same or similar concepts or processes may not be described in detail in some embodiments.

The first embodiment is as follows:

as shown in fig. 1 to 3, the utility model provides a straight weft shuttle, including shuttle body frame 100, shuttle body frame 100 includes shuttle bottom plate 101 and shuttle roof 102 relative in position, the both ends of weft tube 900 are installed respectively on shuttle bottom plate 101 and shuttle roof 102, be equipped with outer guide arm 111 on the shuttle bottom plate 101, be equipped with interior leading edge 121 on the shuttle roof 102, interior leading edge 121 and outer guide arm 111 are used for supporting warp yarn 801 jointly, form the guard space that prevents warp yarn 801 entering between the outer contour of messenger's interior leading edge 121 and the outer contour of outer guide arm 111, weft tube 900 installs in the guard space, the vertical projection of the outer contour of interior leading edge 121 on shuttle bottom plate 101 covers the vertical projection of weft tube 900 on shuttle bottom plate 101.

The utility model discloses install the both ends of woof pipe 900 respectively on shuttle bottom plate 101 and shuttle roof 102, the installation is being straight on the rotatory 90 degrees left and right sides promptly relative prior art, can shorten the length of shuttle body frame 100 front ends to the rear end greatly, reduces the space that occupies, does not change or increase the condition of door circle subassembly diameter a little, can install more shuttles, is favorable to increasing to weaving efficiency. The utility model discloses be equipped with interior bead 121 on shuttle roof 102, simultaneously because the vertical projection of the peripheral profile of interior bead 121 on shuttle bottom plate 101 covers woof pipe 900 vertical projection on shuttle bottom plate 101, utilize interior bead 121 cooperation outer guide arm 111 to support warp 801, form two supports to warp 801, can not contact woof pipe 900 and the woof 901 thereon, effectively avoid the woof that warp and woof pipe unreel to cross winding in advance, ensure that warp 801 continues to carry to the center of door circle subassembly through the shuttle smoothly, finally realize with the weaving work of woof in the central region of door circle subassembly.

In one embodiment, the inner guide edge 121 is formed by the outer peripheral edge of the shuttle top plate 102, i.e., the shuttle top plate 102 serves the dual function of both supporting the shuttle frame 100 and guiding the feed of the warp thread 801. It will be appreciated that in another embodiment, an inner guide bar may be provided on the shuttle top plate 102, similar to the outer guide bar 111, with the inner guide edge 121 being located on the inner guide bar.

In order to make the crossed warp yarns 801 smoothly cross and make the whole shuttle pass through the space formed by the crossed warp yarns 801, the vertical projection of the peripheral outline of the inner guide edge 121 on the shuttle bottom plate 101 is elliptical, so that the distance between the two crossed warp yarns 801 is gradually increased and gradually decreased after the maximum distance is reached, and finally the two crossed warp yarns are crossed again and enter the next crossing. In addition, a shuttle shape with two sharp ends and a wide middle part can be adopted to lead the two crossed warp yarns 801 to smoothly open and cross. Or the egg shape with small front end and large rear end is adopted, so that the two crossed warp yarns 801 can be smoothly crossed, the distance between the two crossed warp yarns 801 can be gradually increased and quickly decreased, the time of crossing each time is shortened, and the efficiency is improved.

In order to position one end of the weft yarn tube 900, a first positioning seat 122 for positioning one end of the weft yarn tube 900 may be provided on the shuttle top plate 102, and the axis of the first positioning seat 122 is perpendicular to the shuttle top plate 102. In order to prevent the warp yarn 801 passing through the outer guide rod 111 and the inner guide edge 121 from contacting the weft yarn tube 900, the distance between two crossed warp yarns 801 is larger than the diameter of the weft yarn tube 900, so that the outer peripheral profile of the inner guide edge 121 has a maximum width line M, the axis of the first positioning seat 122 is perpendicular to the maximum width line M, and the warp yarn 801 is ensured to be spread by the outer guide rod 111 and the inner guide edge 121 far enough away from the weft yarn tube 900 when passing through two sides of the weft yarn tube 900.

In order to gradually increase and rapidly decrease the distance between the two crossed warps 801 in the crossing process, the distance from the axis of the first positioning seat 122 to the front end of the outer peripheral contour of the inner guide edge 121 is L1, the distance from the axis of the first positioning seat 122 to the rear end of the outer peripheral contour of the inner guide edge 121 is L2, and L2 is less than L1. It can be understood that under the condition that the shuttle runs at a constant speed, two crossed warp yarns 801 are in contact with the front end of the outer peripheral profile of the inner guide edge 121 from the crossed and overlapped state, the distance between the two warp yarns 801 gradually increases until the shuttle moves to the end point position of the inner guide edge 121 at the maximum width line, the time taken for the process is T1, the shuttle continues to move, the warp yarns 801 move from the end point position of the maximum width line to the rear end of the outer peripheral profile of the inner guide edge 121 at the maximum width line, the time taken for the process is T2, L1 is greater than L2, therefore, T1 is greater than T2, and the effect of slow opening and fast crossing of the warp yarns 801 is finally formed.

In order to position the other end of the weft yarn tube 900, a second positioning seat 112 for positioning the other end of the weft yarn tube 900 may be disposed on the shuttle base plate 101, and an axis of the second positioning seat 112 coincides with an axis of the first positioning seat 122, so as to ensure reliable positioning of the weft yarn tube 900 and smooth unwinding of weft yarns. Similar to the relationship between L1 and L2, the distance from the axis of the second positioning seat 112 to the front end of the outer peripheral profile of the outer guide rod 111 is L3, the distance from the axis of the second positioning seat 112 to the rear end of the outer peripheral profile of the outer guide rod 111 is L4, and L4 is less than L3, so that the time for the two warps 801 to return to the crossing state after being spread to the maximum distance can be shortened.

In order to obtain the speed of unwinding the weft yarn by the weft yarn tube 900, the first positioning seat 122 or the second positioning seat 112 may be designed to have a wireless code transmitter for detecting the rotation speed of the weft yarn tube 900, and if the rotation speed of the weft yarn tube 900 is detected to be 0, it means that the weft yarn is disconnected or used up, and the host computer may control the shutdown according to the signal of the wireless code transmitter. Under general conditions, if the machine is stopped when weft yarns are used up, weaving waste products can be generated due to the fact that no weft yarn is left in the empty space, in addition, the quality of the weft yarn tube 900 is gradually reduced along with the increase of unwinding time, the rotating speed can be gradually increased, in order to avoid the situation that the machine is stopped when the weft yarns on the weft yarn tube are used up, once the rotating speed of the weft yarn tube 900 is detected to exceed a set value, the host machine considers that the weft yarns on the weft yarn tube are few, the weft yarn tube needs to be replaced in time, the machine is stopped to remind workers of timely replacement, and the situation that the quality is influenced due to the fact that no weft yarn is left in the empty space can be prevented from occurring in woven bags.

Example two:
