DETAILED DESCRIPTION

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-6 As shown: a pneumatic warp beam support for a reeding machine, comprising a frame 1, a warp beam 2, a yarn clamping mechanism 3, a heald frame bracket 4, a yarn expansion bracket 5, a yarn separator guide rail 6, a yarn separator crossbeam 7 and a yarn expansion rod 8, wherein the yarn clamping mechanism 3, the heald frame bracket 4, and the yarn expansion bracket 5 are mounted on the frame 1, the yarn separator crossbeam 7 is mounted on the heald frame bracket 4, the yarn separator guide rail 6 is mounted on the yarn separator crossbeam 7, the yarn expansion rod 8 is mounted on the yarn expansion bracket 5, and the warp yarn 9 on the warp beam 2 is sequentially After passing the yarn expansion rod 8 and the yarn divider guide rail 6, it is clamped by the yarn clamping mechanism 3, and also includes a fixed cross brace 10 and two movable warp beam support mechanisms symmetrically distributed on one side of the frame 1; the movable warp beam support mechanism includes a track 11, a bottom plate 12, a track wheel 13, and a support roller 14. The lower end of the bottom plate 12 is equipped with a track wheel 13 that moves along the track 11. The bottom plate 12 is provided with two support rollers 14 for supporting the warp beam 2. The support rollers 14 are installed through a bearing seat 15 On the bottom plate 12, there are bearings in the bearing seats 15, and the support rollers 14 are installed in the bearings in the bearing seats 15; a gear 16 is installed at the end of the warp beam 2, and a connecting plate 17 is vertically fixed to one end of the bottom plate 12 facing the frame 1, and a rocker rod 18 is hinged on the end surface of the lower part of the connecting plate 17 facing the frame 1, and the connecting plate 17 and the rocker rod 18 are both provided with hinge seats for hinged connection, and the hinge is realized through the hinge seats, and a positioning block 19 is fixed to the upper part of the connecting plate 17, and a connecting rod 20 is fixed on the rocker rod 18, and a locking claw 21 that cooperates with the gear 16 is fixed on the connecting rod 20, and when the rocker rod 18 contacts the positioning block 19, the locking claw 21 is engaged with the gear 16; the fixed cross brace 10 is horizontally fixed on the frame 1, and two fixed frames 22 are slidably mounted on the fixed cross brace 10, and a pneumatic jacking mechanism is hinged on the fixed frame 22, and the output end of the pneumatic jacking mechanism is hinged to the corresponding rocker rod 18.

[0020] Further, in this embodiment, if Figure 4As shown, the pneumatic push mechanism includes a cylinder body 23, a piston head 24, a piston rod 25, a first spring 26, a locking block 27, and a set screw 28. The cylinder body 23 is provided with an air inlet 29. The cylinder body 23 is hinged to the fixed frame 22. The fixed frame 22 has an articulated seat articulated to the cylinder body 23. The articulation is achieved through the articulated seat. The piston head 24 is slidably sealed and installed in the cylinder body 23. One end of the piston rod 25 is connected to the piston head 24 and the other end extends out of the cylinder body 23. The first spring 26 is sleeved on the piston rod 25, and the two ends of the first spring 26 are respectively connected to the piston head 24 and the cylinder body 23. The locking block 27 is slidably sleeved on the rod portion of the piston rod 25 extending out of the cylinder body 23, and the set screw 28 is threadedly connected to the locking block 27. The set screw 28 is used to press the piston rod 25 to fix the locking block 27 to the piston rod 25.

[0021] Furthermore, in this embodiment, in order to enable the pneumatic pushing mechanism to drive the movable warp beam support mechanism to move, the frame 1 is fixed to the ground by anchor bolts 30, so that the frame 1 is fixed to facilitate the operation of the pneumatic pushing mechanism.

[0022] Furthermore, in this embodiment, in order to facilitate the locking claw 21 to disengage from the gear 16, a spring seat 31 is fixed on the two base plates 12, and a second spring 32 is installed on the spring seat 31. The other end of the second spring 32 is connected to the rocker arm 18. After the pneumatic pushing mechanism is cut off, the second spring 32 can push the rocker arm 18 to move the connecting rod 20 away from the warp shaft 2, thereby disengaging the locking claw 21 from the gear 16.

[0023] Furthermore, in this embodiment, in order to maintain a suitable spacing between the movable warp beam support mechanism and the frame 1 , a limit block 33 is fixed on the track 11 , and the limit block 33 can abut against the track wheel 13 , thereby limiting the movement of the track wheel 13 .

[0024] Furthermore, in this embodiment, in order to facilitate the pneumatic pushing mechanism to pull the movable warp beam support mechanism toward the frame 1, a baffle 34 is fixed at the lower end of the connecting plate 17, and the baffle 34 is used to limit the rotation angle of the rocker arm 18. When the rocker arm 18 abuts against the baffle 34, the baffle 34 limits the rocker arm 18 from continuing to rotate, so that the pneumatic pushing mechanism pulls the movable warp beam support mechanism by pulling the rocker arm 18.

[0025] The working principle of this embodiment is as follows: the warp beam 2 is placed on the support rollers 14, wherein two support rollers 14 of one movable warp beam support mechanism support one end of the warp beam 2, and two support rollers 14 of another movable warp beam support mechanism support the other end of the warp beam 2, so that the warp beam 2 remains stable and can rotate on the support rollers 14 after being subjected to force, and the warp yarn 9 on the warp beam 2 passes through the yarn expansion rod 8 and the yarn divider guide rail 6 in turn and is clamped by the yarn clamping mechanism 3, as shown in FIG. Figure 1 As shown;

[0026] When the yarn is inflated, the two pneumatic pushing mechanisms work synchronously, and air is ventilated to the cylinder body 23 through the air inlet 29. The air pressure in the cylinder body 23 increases, and the piston head 24 and the piston rod 25 move toward the swing rod 18. The first spring 26 is compressed, and the piston rod 25 drives the swing rod 18 to rotate toward the positioning block 19. The second spring 32 is compressed, and the locking claw 21 will first clamp the gear 16 to prevent the warp beam 2 from rotating. Then the swing rod 18 will abut against the positioning block 19, thereby driving the bottom plate 12 to move, and the track wheel 13 moves away from the frame 1 on the track 11. The warp beam 2 moves with the moving warp beam support mechanism, thereby tightening the warp yarn 9. Figure 2 As shown; after the warp yarn 9 is tightened, the locking block 27 is moved on the piston rod 25 so that the locking block 27 abuts against the cylinder body 23, and then the set screw 28 is tightened so that the set screw 28 presses the piston rod 25, so that the locking block 27 is fixed on the piston rod 25. In this way, the cylinder body 23 can be prevented from contracting the piston rod 25 due to air leakage, so as to ensure that the position of the warp beam 2 does not move and the warp yarn 9 is always tightened;

[0027] When the warp beam 2 needs to be replaced, the set screw 28 is unscrewed, the locking block 27 no longer locks the piston rod 25, the air inlet 29 is cut off, the air pressure in the cylinder body 23 is reduced, and under the action of the elastic restoring force of the first spring 26, the piston head 24 and the piston rod 25 move toward the frame 1, the piston rod 25 shrinks into the cylinder body 23, and the piston rod 25 pulls the swing rod 18 to rotate. The second spring 32 plays an auxiliary role. The second spring 32 pushes the swing rod 18 so that the swing rod 18 abuts against the baffle 34, and the locking claw 21 is away from the gear 16 and no longer jams the gear 16. When the swing rod 18 abuts against the baffle 34, it cannot continue to rotate. The piston rod 25 pulls the swing rod 18, the connecting plate 17, the movable warp beam support mechanism and the warp beam 2 to move toward the frame 1. When the track wheel 13 moves to the limit block 33, it cannot continue to move. At this time, the movable warp beam support mechanism is closest to the frame 1. Since the locking claw 21 is already away from the gear 16 at this time, it is convenient to replace the warp beam 2.

[0028] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
