DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 The utility model provides a technical solution: an air jet loom that is easy to adjust the nozzle, comprising: a frame 1 and a nozzle body 6, a bracket 2 is installed on the top of the frame 1, an air jet reed 3 is installed in the middle of the bracket 2, an air expansion roller 4 is installed in the middle of the frame 1, a control panel 5 is installed on one side of the frame 1, and the nozzle body 6 is arranged on the top of the frame 1;
[0024] A fixing frame 7 is connected to one side of the nozzle body 6, a mounting frame 8 is connected to one side of the fixing frame 7, a supporting frame 9 is sleeved on one end of the mounting frame 8, a screw 10 penetrating the supporting frame 9 is connected to the bottom of the mounting frame 8, a connecting block 11 is installed at the bottom of the supporting frame 9, a gear 12 is installed on the outer side of the connecting block 11, a movable frame 13 is sleeved on the outer side of the gear 12, a tooth block 14 is installed inside the movable frame 13 through a groove, a sliding block 15 is connected to one side of the movable frame 13 through a slide groove, a telescopic rod 16 is connected to the top of the sliding block 15, a telescopic spring 17 is installed inside the telescopic rod 16, and the top of the telescopic rod 16 is welded to the bottom of the supporting frame 9.
[0025] During specific implementation, the jet loom with easy nozzle adjustment can pull the support frame 9 upwards and stretch the telescopic rod 16 when the nozzle body 6 needs to be adjusted according to the use requirements. At the same time, the support frame 9 drives the connecting block 11 and the outer gear 12 to move upwards, so that the gear 12 is separated from the tooth block 14. At this time, there is no tooth block 14 to limit the gear 12, so the support frame 9 can be rotated so that the support frame 9 can rotate through the movable frame 13, and when the support frame 9 rotates, it will drive the telescopic rod 16 and the sliding block 15 to slide along the slide groove on the surface of the movable frame 13. The rotation of the support frame 9 will drive the mounting frame 8 and the fixed frame 7 to rotate, and the angle of the nozzle body 6 can be adjusted. To make adjustments, when the angle of the nozzle body 6 is adjusted to a suitable position, release the support frame 9, and the support frame 9 is reset by the telescopic spring 17 inside the telescopic rod 16, so that the support frame 9 moves downward, and drives the connecting block 11 and the gear 12 to move downward, and docks the gear 12 with the gear block 14, so that the position of the nozzle body 6 can be fixed, and at the same time, the screw 10 can be rotated. Since the screw 10 and the support frame 9 are threadedly connected, and the screw 10 is connected to the mounting frame 8 through a bearing, rotating the screw 10 at this time will cause the mounting frame 8 to drive the fixing frame 7 to move up and down, thereby changing the height of the nozzle body 6, which is convenient for the user to adjust the position of the nozzle body 6.
[0026] See also Figure 1 , Figure 3 and Figure 4 It can be seen that when in use, the nozzle body 6 can be rotated along the center position of the movable frame 13 according to the use requirements, or the height of the entire nozzle body 6 can be adjusted, so that the user can adjust the nozzle body 6 conveniently.
[0027] A positioning block 18 is installed on the outer side of the nozzle body 6, and a clamping block 19 is inserted at one end of the positioning block 18. A movable spring 20 is connected between the clamping block 19 and the groove of the fixing frame 7. A wedge block 21 is provided at one end of the clamping block 19, and a push rod 22 that passes through the fixing frame 7 is connected to one side of the wedge block 21. A compression spring 23 is connected between the wedge block 21 and the groove of the fixing frame 7, and the clamping block 19 is docked in the groove of the fixing frame 7 through a groove that matches the size of the clamping block 19.
[0028] In specific implementation, the jet loom with easy nozzle adjustment can dock the nozzle body 6 to one side of the fixing frame 7 when the nozzle needs to be replaced and installed, and the positioning blocks 18 at both ends of the nozzle body 6 can be docked into the grooves of the fixing frame 7, and the pull rod can be pulled at the same time. Both ends of the block 19 are arc structures. During the installation process, the positioning block 18 will be squeezed by the positioning block 18, so that the block 19 moves upward and squeezes the movable spring 20 at the same time. After the groove of the positioning block 18 moves to the position of the block 19, the pull rod is released, and the pull rod will be reset by the compression spring 23, and the wedge block 21 at one end of the pull rod will be pressed against the block. 19 is squeezed, thereby squeezing the block 19 into the groove of the positioning block 18. At this time, the nozzle body 6 can be installed on one side of the fixing frame 7, which is convenient for the user to quickly install and fix the nozzle body 6. Conversely, when the nozzle body 6 needs to be replaced, the push rod 22 can be pulled, and the push rod 22 drives the wedge block 21 to move to the outside of the fixing frame 7, so that the wedge block 21 does not squeeze the block 19, and then the block 19 will be reset by the movable spring 20 and move out of the groove of the positioning block 18. At this time, the nozzle body 6 can be removed from one side of the fixing frame 7, which is convenient for the user to replace the nozzle body 6.
[0029] See also Figure 2 and Figure 5 It can be seen that when in use, the nozzle body 6 can be disassembled from the fixing frame 7 according to the use requirements, and then the nozzle body 6 can be replaced, which is convenient for the user to quickly replace the nozzle body 6.
[0030] To sum up: when the jet loom with an adjustable nozzle is working, the frame 1 is placed in a stable position, and then the yarn can be passed through the air expansion roller 4, and then the compressed air flow ejected from the nozzle is used to generate friction traction on the weft yarn, and then the weft yarn is quickly passed through the shed to cooperate with the warp yarn to weave cloth. This is the prior art and will not be elaborated on here. This is the use feature of the jet loom with an adjustable nozzle. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.
