[0021] Further, the side of the limiting ring 31 facing the support base 1 is fixedly provided with a protective sleeve 5, the connecting rod one 41, the connecting rod two 42 and the rollers 45 are located in the middle of the protective sleeve 5, and the protective sleeve 5 and the support base 1 leave a gap for the guide cylinder 3 to reciprocally slide on the hexagonal column. By adopting the above-mentioned protective sleeve 5, the components of the sliding mechanism 4 can be hidden and protected, and the operator can be prevented from being injured by the moving components in the sliding mechanism 4.
[0022] Further, the protective sleeve 5 includes a pair of semicircular arc plates 51 which are bolted at the two ends, and the side of the limiting ring 31 facing the support base 1 is fixedly provided with an annular protrusion 31a for clamping the two semicircular arc plates 51. By adopting the detachable protective sleeve 5, the worker can conveniently check and maintain the components of the sliding mechanism 4.
[0023] Further, the end of the semicircular arc plate 51 away from the limiting ring 31 is fixedly provided with a semicircular arc-shaped dust screen 52, and the end of the dust screen 52 away from the protective sleeve 5 contacts the side wall of the support base 1. By adopting the above-mentioned dust screen 52, the fixed impurities such as dust can be blocked from entering the protective sleeve 5, so as to protect the normal operation of the sliding mechanism 4.
[0024] Further, the support base 1 includes a seat body 11 and a box body 12 with an opening downward, the top of the seat body 11 is fixedly provided with a positioning protrusion 11a inserted into the inside of the box body 12, the both sides of the positioning protrusion 11a are provided with threaded holes 11b, the threaded holes 11b are threadedly connected with screws 11c penetrating through the wall of the box body 12, and a support cylinder 12a is fixedly inserted at the center position of the box body 12, and the cylindrical body 22 rotates through the support cylinder 12a. By adopting the above-mentioned detachable support base 1 structure, the worker can conveniently check and maintain the components of the turnover assembly 43 inside.
[0025] Further, the turnover assembly 43 comprises a sliding plate 43a slidingly arranged inside the box body 12 and vertically positioned on top of the positioning protrusion 11a, a screw rod 43b rotatably arranged inside the box body 12 and horizontally positioned below the supporting cylinder 12a, a servo motor 43c driving the screw rod 43b to rotate, a nut 43d fixed to one side of the sliding plate 43a and threadedly connected with the screw rod 43b, a pair of long slot holes 43e formed on the sliding plate 43a and respectively positioned on the upper and lower sides of the supporting cylinder 12a, a pair of long grooves 43f vertically and horizontally arranged and respectively formed on the inner side walls of the long slot holes 43e, a slide rod 43g having two ends slidingly connected with the long grooves 43f, a pair of long slot holes 43h formed on the side walls of the box body 12 and communicating with the interior of the box body 12, the supporting cylinder 12a and the screw rod 43b slidingly penetrating through the sliding plate 43a, the servo motor 43c fixed on the outer side of the box body 12 and having an output end rotatably penetrating into the interior of the box body 12 and connected with the screw rod 43b, the two long slot holes 43h respectively positioned at the hinged connection between the connecting rod one 41 and the side wall of the box body 12, and the connecting rod one 41 having an extension 41a penetrating into the long slot hole 43h and fixedly connected with the slide rod 43g.
[0026] When the connecting rod one 41 needs to be driven to turn over, the servo motor 43c drives the screw rod 43b to rotate first, then the nut 43d translates along the screw rod 43b, and drives the sliding plate 43a to slide relative to the interior of the box body 12, and the slide rod 43g slidingly arranged in the long slot hole 43e will horizontally move away from or close to the long slot hole 43h along with the sliding plate 43a, since the extension 41a of the connecting rod one 41 penetrates through the long slot hole 43h and has one end extending into the long slot hole 43e and fixedly connected with the slide rod 43g, therefore, under the horizontal movement of the sliding plate 43a, the slide rod 43g not only moves horizontally along with the sliding plate 43a, but also slides up and down relative to the long groove 43f, and finally the connecting rod one 41 will move up and down relative to the box body 12 under the movement of the slide rod 43g, and then the other components of the sliding mechanism 4 are cooperated to realize the effect of controlling the reciprocating sliding of the guide cylinder 3.
[0027] Further, the two turnover assemblies 43 in the two sliding mechanisms 4 share one servo motor 43c, the output end of the servo motor 43c is fixedly connected with a transmission shaft 43i rotatably penetrating through the two box bodies 12 and horizontally positioned below the guide cylinder 3, the two screw rods 43b are oppositely arranged and fixed on the transmission shaft 43i. By using the transmission shaft 43i, one servo motor 43c can be saved under the condition of not affecting the synchronous reverse working of the two sliding mechanisms 4, and then the manufacturing cost and working energy consumption of the structure are reduced.
[0028] Working principle of the embodiment:
[0029] When the projectile loom works, the turning assembly 43 on the support base 1 drives the two connecting rods 41 on it to turn towards the axis of the hexagonal prism 21, and then the U-shaped plate 44 connected with the two connecting rods 41 turns towards the axis of the guide cylinder 3. Since the U-shaped plate 44 and the support base 1 are also connected with the connecting rod 42, the U-shaped plate 44 will keep the vertical posture and translate along the end of the guide cylinder 3 with the middle roller 45. Since the angle between the two pairs of connecting rods 41 and 42 is continuously reduced, the U-shaped plate 44 and the roller 45 will push the guide cylinder 3 to slide away from the support base 1 in the horizontal direction. At the same time, the turning assembly 43 on the other support base 1 drives the two connecting rods 41 to turn away from the axis of the hexagonal prism 21, so that the U-shaped plate 44 and the roller 45 are away from the axis of the guide cylinder 3 in the vertical direction, and slide towards the support base 1 in the horizontal direction. Finally, the turning assembly 43 on the two support bases 1 repeats the above operation in reverse, so as to realize the effect of rotating and reciprocating sliding of the guide cylinder 3. Not only can it overcome the defect that the warp yarns are in contact with the same position of the guide cylinder 3 for a long time, but also can make the warp yarns wear the surface of the guide cylinder 3 uniformly, so as to avoid the small grooves on the guide cylinder 3, effectively keep the surface of the guide cylinder 3 flat, and prolong the service life of the guide cylinder 3. Since the U-shaped plate 44 rolls on the end surface of the guide cylinder 3 through the roller 45, it will not affect the rotation of the guide roller when pushing the guide cylinder 3 to slide.
