The relevant dimensions are not drawn to scale in figure 2 for clarity of illustration. The bottom surface of the shuttle bottom plate 31 refers to the surface of the shuttle bottom plate 31 facing the reed blades, and can be generally arranged to be parallel to the circular arc surface of the shuttle circumference running track.
In the invention, the limiting groove 41 is arranged on the reed wire 4, namely, the limiting groove is arranged between the upper door ring 1 and the lower door ring 2, the shuttle wheel 32 is matched with the limiting groove 41, namely, the shuttle wheel 32 is designed to be in matched contact with the vertically arranged reed wire 4 and is not in contact with the upper door ring 1 and the lower door ring 2 any more, so that the shuttle wheel 32 can be prevented from rolling warp yarns in the running process of the shuttle 3, the original strength and finish degree of the warp yarns can be kept, and the quality of a plastic woven bag is ensured.

As a commonly used specification, the diameter D of the shuttle wheel 32 may be selected to be 50mm, and the diameter S may be selected to be 1.5 to 5mm, which can substantially satisfy the rolling of the shuttle wheel 32 and the passing of the warp yarn. Of course, the diameter D of the shuttle wheel 32 can be selected to be larger when the spatial structure condition of the shuttle 3 allows, and the larger the diameter of the shuttle wheel 32 is, the smaller the number of revolutions of the shuttle wheel 32, that is, the slower the rotation speed of the shuttle wheel 32, the larger the diameter of the upper door ring 1 and the lower door ring 2 is, and the lower the number of revolutions of the shuttle wheel 3 is, thereby being beneficial to the smoothness of the operation of the shuttle 3, for example, 55mm, 60mm, etc. can be selected, and accordingly, S can be selected to be 2.5-5 mm. In the case that the spatial structure condition of the shuttle 3 is not allowed, for example, in order to ensure the installation space of the weft yarn spindle, the shuttle wheel 32 cannot protrude too far from the inner side of the shuttle bottom plate 31, or the shuttle bottom plate 31 and the weft yarn spindle 34 cannot be too far away from the reed wire 4 due to the size of the crossing angle of the warp yarns, otherwise the weft yarns are collided, so that D may be smaller than 50mm, for example, 45mm or 40mm, and the like, the selection range of S is correspondingly reduced, and the condition that S is less than or equal to 0.1D needs to be satisfied.
As shown in fig. 4 and 5, in the present embodiment, two shuttle wheels 32 are provided and are provided centrally on the shuttle base plate 31, the two shuttle wheels 32 are arranged back and forth in the direction of the circular motion of the shuttle 3, and the reed wire 4 is provided with a limit groove 41. In the case where the shuttle 3 can be ensured to run stably, the production cost can be reduced by using the minimum number of shuttle wheels 32 and providing the minimum number of limit grooves 41.

In order to mount the shuttle wheel 32, a through hole 311 for mounting the shuttle wheel 32 may be provided on the shuttle bottom plate 31, the shuttle wheel 32 is mounted on the shuttle bottom plate 31 through the wheel shaft 33, the shuttle wheel 32 is generally formed by injecting polyurethane or rubber on the outer periphery of a steel ring, a bearing is mounted in the steel ring, then the inner ring of the bearing is fixed with the wheel shaft 33, and then the wheel shaft 33 is fixed on the shuttle bottom plate 31. Alternatively, the shuttle wheel 32 may be formed by directly injecting polyurethane or rubber on the outer race of the bearing and then fixing the inner race of the bearing to the wheel shaft 33. The through hole 311 is arranged, so that the material consumption of the shuttle bottom plate 31 can be saved, the inertia of the shuttle 3 is reduced, the stop is quicker, and meanwhile, the shuttle wheel 32 can drive airflow to flow in the through hole 311 in high-speed rotation, so that the bearing on the shuttle wheel 32 can be effectively radiated, and the service life of the bearing is ensured. Alternatively, a blind hole may be provided in the bottom surface of the shuttle bottom plate 31, and the shuttle wheel 32 may be mounted to the blind hole through the wheel shaft 33. In addition to the hole structure machined on the shuttle bottom plate, the bottom surface of the shuttle bottom plate 31 may also be provided with a mounting seat, the shuttle wheel is mounted on the mounting seat through a wheel shaft 33, and the shuttle wheel is totally protruded out of the bottom surface of the shuttle bottom plate.
In this embodiment, the axle 33 is parallel to the reed wires 4, and the shuttle wheel 32 can be considered to vertically roll on the reed wires 4, and the reference is vertically set according to the reed wires 4, and the shuttle wheel 32 can be considered to horizontally rotate, and the centrifugal effect generated by the circular motion of the shuttle 3 can prevent the shuttle wheel 32 from being basically affected by the acting force in the gravity direction, so that the matching effect with the limiting groove 41 is better, and the running stability of the shuttle 3 is higher.
Example two:
as shown in fig. 7 and 8, the number of the shuttle wheels 32 in this embodiment is three, two shuttle wheels 32 are disposed vertically symmetrically, the other shuttle wheel 32 is disposed centrally on the shuttle bottom plate 31, the other shuttle wheel 32 is arranged back and forth in the direction of the circular motion of the shuttle 3 with respect to the two shuttle wheels 32, and the reed wire 4 is provided with three limit grooves 41. Two symmetrical shuttle wheels 32 may be provided in front and a single shuttle wheel 32 in back, or two symmetrical shuttle wheels 32 in back and a single shuttle wheel 32 in front.
Other contents not described in this embodiment may refer to embodiment one.
Example three:
as shown in fig. 9 and 10, the number of the shuttle wheels 32 in the present embodiment is four, two of the shuttle wheels 32 are symmetrically disposed up and down on the shuttle base plate 31 at an interval of L1, the other two shuttle wheels 32 are also symmetrically disposed up and down on the shuttle base plate 31 at an interval of L2, L1 is L2, and the reed wire 4 is provided with two limiting grooves 41. The shuttle wheels 32 are increased in number, and the shuttle 3 can be supported more and can be more stable in operation. It is understood that L1 may not be equal to L2, and the reed wire 4 is provided with four limit grooves 41. Because the interval between upper door circle and the lower door circle is limited, the quantity that the shuttle wheel set up in a row in the vertical direction should not too much yet, the quantity of spacing recess on the reed 4 can not too much promptly.
Other contents not described in this embodiment may refer to embodiment one.
Example four:
instead of being perpendicular to the reed wire 4, the axle 33 can also be designed to be oblique to the reed wire 4, for example, as shown in fig. 11, and at this time, the shuttle wheel 32 can also bear the acting force in the vertical direction, so as to play a certain supporting role for the shuttle 3 and also make the shuttle 3 move more stably. In order to support the shuttle wheel in both the up and down directions, it is preferable that the shuttle wheel 32 is inclined symmetrically up and down. It will be appreciated that instead of the two shuttle wheels shown in figure 11 being mounted in an outwardly opening figure, the two shuttle wheels could be mounted in an inclined manner in an inwardly opening figure.
