Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weft guide frames, in particular to a weft coil placing guide frame for a glass fiber weaving machine. Background Art
[0002] Glass fiber mesh cloth is a plain woven fabric with untwisted coarse yarn and is an important base material for hand-laid FRP. The strength of glass fiber mesh cloth lies mainly in the warp and weft directions of the fabric. At present, glass fiber cloth is generally woven by a weaving machine.
[0003] At present, the weft thread of the glass fiber weaving machine is generally guided by a guide mechanism and then cooperated with the warp slider inside the weaving machine. The traditional method is to directly place the wire roll on the ground, which has poor stability and is easy to collapse. At present, some weaving machines are also equipped with a wire roll rack, but the existing limit rolls are mostly placed horizontally and there is only one. In this structure, when the wire is drawn, the wire roll will be dragged by the weft thread and rotate with it. The friction greatly reduces the service life of the wire roll, and when a group of weft threads is used up, the machine is generally stopped to replace the wire roll, which leads to reduced production efficiency. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
[0004] The purpose of the utility model is to provide a weft wire coil placement guide frame for a glass fiber weaving machine. When a coil of weft wire is used up, the turntable can be directly rotated to switch to the next group of weft wires. When the three groups of weft wires are connected end to end, there is no need to even stop the machine, which greatly improves production efficiency. At the same time, the wire coil is sleeved on the wire coil placement tube, which improves the stability of the wire coil. Secondly, since the wire coil placement tube is parallel to the axial center line of the guide ring, the wire coil itself rarely rotates when the wire is drawn, avoiding continuous friction between the inner wall of the wire coil and the wire coil placement tube, thereby increasing the service life of the wire coil, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a weft wire coil placement guide frame for a glass fiber weaving machine, comprising an upright pole, a connecting rod, a guide ring, a turntable, an axle rod, a wire coil placement tube, a handle push rod, a cross bar and a connecting angle steel, wherein a guide ring is arranged at the top of the upright pole through the connecting rod, a connecting angle steel is arranged at the bottom end of the upright pole, an axle rod is arranged at the center position of the turntable, the axle rod passes through the upright pole and is rotatably connected to the upright pole, three wire coil placement tubes and a handle push rod are evenly arranged in a ring shape on the turntable with the axle rod as the center, the wire coil placement tubes are all arranged at one end of the turntable close to the upright pole, the handle push rod is penetrated through the turntable, cross bars are arranged on both sides of the top of the upright pole, the upright pole and the cross bar are both provided with positioning holes, the distances between the positioning holes of the upright pole and the positioning holes of the cross bar and the axle rod are consistent and both cooperate with the handle push rod.
[0006] Preferably, the utility model provides a weft wire coil placement guide frame for a glass fiber weaving machine, wherein the interior of the wire coil placement tube is hollow, and the end of the wire coil placement tube away from the turntable cooperates with a limiting piston.
[0007] Preferably, the utility model provides a weft thread coil placement guide frame for a glass fiber weaving machine, wherein the shaft rod is located at both ends of the vertical rod and limit nuts are respectively provided.

[0010] Preferably, the utility model provides a weft thread coil placement guide frame for a glass fiber weaving machine, wherein a handle ball head is threadedly mounted on one end of the handle push rod away from the vertical rod.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The turntable is equipped with three wire reel placement tubes and a handle push rod, so three weft wire reels can be placed at the same time. When a roll of weft wire is used up, the turntable can be directly turned to switch to the next group of weft wires. When the three groups of weft wires are connected end to end, there is no need to even stop the machine, which greatly improves production efficiency. At the same time, the wire reel is put on the wire reel placement tube, which improves the stability of the wire reel.

[0019] See also Figure 1 The utility model provides a technical solution: a weft wire coil placement guide frame for a glass fiber weaving machine, comprising a vertical pole 1, a connecting rod 2, a guide ring 3, a turntable 4, an axle rod 5, a wire coil placement tube 6, a handle push rod 7, a cross bar 8 and a connecting angle steel 9. The top of the vertical pole 1 is provided with a guide ring 3 through the connecting rod 2, and the bottom of the vertical pole 1 is provided with a connecting angle steel 9. The center position of the turntable 4 is provided with an axle rod 5, which passes through the vertical pole 1 and is rotatably connected to the vertical pole 1. The axle rod 5 is located at both ends of the vertical pole 1 and is respectively provided with limiting nuts 12 to ensure that the axle rod 5 will not separate from the vertical pole 1 and will not loosen, thereby ensuring the stability of the turntable 4. The turntable 4 is evenly provided with three wire coil placement tubes 6 and a handle push rod 7 in a ring shape with the axle rod 5 as the center. The inside of the wire coil placement tube 6 is hollow, and the end of the wire coil placement tube 6 away from the turntable 4 cooperates with the limiting piston 11. By setting a limit piston 11, it is ensured that the wire reel will not fall off when it is sleeved on the wire reel placement tube 6. The wire reel placement tube 6 is arranged at one end of the turntable 4 close to the vertical pole 1, and the handle push rod 7 is passed through the turntable 4. Cross bars 8 are arranged on both sides of the top of the vertical pole 1. The vertical pole 1 and the cross bar 8 are both provided with positioning holes 10. The distances between the positioning holes 10 of the vertical pole 1 and the positioning holes 10 of the cross bar 8 and the shaft rod 5 are consistent and both cooperate with the handle push rod 7. A limit plate 13 is provided on the part of the handle push rod 7 located between the turntable 4 and the vertical pole 1 to limit the handle push rod 7 to avoid injuries caused by the hand hitting the turntable due to unlimited position during manual operation. The handle push rod 7 has a conical head near the end of the vertical pole 1 so that the end of the handle push rod 7 can be smoothly inserted into the corresponding positioning hole 10, and the handle push rod 7 is threadedly installed with a handle ball head 14 at the end away from the vertical pole 1 to facilitate better operation of the handle push rod 7.
[0020] Assembly method and principle of use: Install the three wire coil placement tubes 6 evenly at the reserved holes of the turntable 4 by welding, then pass the handle push rod 7 through the turntable 4, and then install the handle ball head 14 on the outer end of the handle push rod 7. Then weld the crossbar 8 to the vertical pole 1, and then weld the connecting angle steel 9 to the bottom of the vertical pole 1, and weld the connecting rod 2 with the guide ring 3 to the top of the vertical pole 1. Next, connect the turntable 4 to the vertical pole 1 through the shaft 5, and limit it with the limit nut 12 to complete the assembly. Before use, the whole is installed on the side of the weft inlet and outlet mechanism of the braiding machine through the connecting angle steel 9 and bolts. When in use, the glass fiber wire coil is put on the wire coil placement tube 6, and the three groups of weft wires can be connected end to end in advance, and then the limit piston 11 is inserted into the end of the wire coil placement tube 6 to limit the wire coil to prevent the wire coil from falling. Then the glass fiber wire passes through the guide ring 3 and is connected to the needle of the weft wire inlet and outlet mechanism of the braiding machine, and then the handle push rod 7 is inserted into the positioning hole 10 of the corresponding vertical pole 1 or cross bar 8 at this time to fix the turntable 4. When a weft wire coil is used up, the handle push rod 7 is pulled out to make the end of the handle push rod 7 disengage from the positioning hole 10, the turntable 4 is rotated, and the next wire coil is moved to the position of the guide ring 3, and the handle push rod 7 is pushed to make the handle push rod 7 inserted into the positioning hole 10 of the corresponding vertical pole 1 or cross bar 8 at this time, and the positioning of the turntable 4 is completed again. The utility model has a reasonable structure. The turntable 4 is provided with three wire roll placement tubes 6 and a handle push rod 7, so three weft wire rolls can be placed at the same time. When a roll of weft wire is used up, the turntable 4 can be directly rotated to switch to the next group of weft wires. When the three groups of weft wires are connected end to end, there is no need to even stop the machine, which greatly improves the production efficiency. At the same time, the wire roll is sleeved on the wire roll placement tube 6, which firstly improves the stability of the wire roll. Secondly, since the wire roll placement tube 6 is coaxial with the guide ring 3, the wire roll itself rarely rotates when the wire is drawn, avoiding continuous friction between the inner wall of the wire roll and the wire roll placement tube 6, thereby increasing the service life of the wire roll. The integrated guiding and placement structure is adopted, and the space utilization is more reasonable, and there is no need to install separately.
