[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 The existing water jet loom uses a weft insertion mechanism that involves removing and installing screws to assemble and disassemble the spring steel wire 17, which is inconvenient for quick assembly and disassembly of the spring steel wire 17. In order to solve this technical problem, this embodiment discloses the following technical content.

[0029] The weft insertion mechanism for a water jet loom includes a drive shaft 1, a first gear 2, a mounting frame 3, a motor 4, a second gear 5, a connecting roller 6, a third gear 7, a connecting plate 8, a base 9, a first connecting rod 10, a second connecting rod 11, a top seat 12, an operating plate 13, an insert rod 14, a spring ring 15, an insert plate 16, and a spring steel wire 17.

[0030] The drive shaft 1 rotates through a drive assembly, which includes a first gear 2, a mounting bracket 3, a motor 4, a second gear 5, a connecting roller 6, and a third gear 7. The first gear 2 is fixed at both the front and rear ends of the drive shaft 1. The mounting bracket 3 is provided below the drive shaft 1. The motor 4 is fixed at the front end of the mounting bracket 3, and the second gear 5 is fixed at the output end of the motor 4. The connecting roller 6 is fixed at the rear side of the second gear 5, and the third gear 7 is fixed at the rear side of the connecting roller 6. The top ends of the second gear 5 and the third gear 7 are meshed with the first gear 2.

[0031] When it is necessary to strike and press the weft of the fabric, the motor 4 inside the drive assembly is started. The motor 4 drives the second gear 5, the connecting roller 6 and the third gear 7 to rotate, thereby rotating the first gear 2 and the drive shaft 1. This causes the spring steel wire 17 installed on the drive shaft 1 to swing and strike and press the weft of the fabric. A set of motors 4 can drive the drive shaft 1 to rotate. The angle of rotation of the drive shaft 1 driven by the motor 4 is controlled by the controller (the controller of the motor 4 is not shown).

[0032] A connecting plate 8 is fixed to the outer side of the drive shaft 1, and the bottom end of the base 9 is fixed to the outer end of the connecting plate 8 by screws. A first connecting rod 10 is fixed to the upper surface of the base 9, and the bottom end of the second connecting rod 11 is fixed to the inside of the first connecting rod 10 by set screws. A top seat 12 is fixed to the upper surface of the second connecting rod 11. Fixing components are installed inside the top seat 12 and the base 9. Insert plates 16 are fixed to the top and bottom ends of the spring steel wire 17. The insert plates 16 are fixedly connected to the top seat 12 and the base 9 by fixing components.

[0033] The fixing assembly includes an operating plate 13, a plug rod 14, and a spring ring 15. The plug rod 14 is fixed to the inner side of the operating plate 13, and the spring ring 15 is provided on the outer side of the plug rod 14. The plug rod 14 is slidably installed inside the base 9 and the top seat 12. The spring ring 15 is fixed to the outer end of the base 9 and the top seat 12. The plug plate 16 has holes for the plug rod 14 to be inserted at equal intervals inside. The base 9 and the top seat 12 have mounting grooves for receiving the plug plate 16 inside.

[0034] When it is necessary to replace the spring steel wire 17, pull the operating plate 13 on the top seat 12 outward, the insertion rod 14 moves outward, the spring ring 15 is pressed, so that the insertion rod 14 leaves the mounting slot of the base 9 and the top seat 12, the insertion rod 14 leaves the insertion plate 16, and the insertion plate 16 is dislodged from the inside of the top seat 12. Then, pull the operating plate 13 on the base 9 outward with one hand, hold the two sets of operating plates 13 on the left and right with one hand at the same time, and lift the spring steel wire 17 and the insertion plate 16 upward with the other hand to remove the spring steel wire 17.

[0035] Working principle: The drive assembly consisting of the first gear 2, mounting frame 3, motor 4, second gear 5, connecting roller 6 and third gear 7 drives the transmission shaft 1 to rotate, thereby causing the spring steel wire 17 to rotate and strike the weft thread of the fabric. When the spring steel wire 17 needs to be replaced, first pull the operating plate 13 on the top seat 12 outward to remove the insert plate 16 inside the top seat 12, then pull the operating plate 13 on the base 9 outward to remove the insert plate 16 inside the base 9, and the spring steel wire 17 can be removed.

[0036] The second connecting rod 11 is raised and lowered inside the first connecting rod 10 to adjust the distance between the top seat 12 and the base 9, thereby installing spring steel wires 17 of different sizes;

[0037] When it is necessary to disassemble the weft insertion mechanism, remove the first connecting rod 10 and the second connecting rod 11; the connecting screws connecting the first connecting rod 10 and the second connecting rod 11 are removed, and the top seat 12 and the base 9 can be separated. Remove the screws connecting the connecting plate 8 and the base 9, and the connecting plate 8 and the base 9 can be separated.

[0038] The above completes a series of operations for the beat-up mechanism of the water jet loom. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.
