Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, specifically to a weft insertion water pipe for water jet looms. Background Technology

[0002] Water jet looms are shuttleless looms that use jet water to guide the weft yarn through the shed. Water jet weft insertion has a greater frictional traction force on the weft yarn than air jet weft insertion, and its diffusion is smaller. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. The weft insertion water pipe is an important component of water jet looms.

[0003] According to the search, Chinese patent document, publication number CN209098899U, discloses a weft insertion water pipe for a water jet loom. It adopts a processing method of pressing the water pipe body material, and the water pipe and the end are integrated into a single structure, which does not require welding. It has high body strength and significantly improves the anti-breakage strength of the weft insertion water pipe. It also has low manufacturing cost. However, the weft insertion water pipe uses nuts to connect to the nozzle and the water pump respectively. It is inconvenient to replace the water pipe and the connection end. In addition, the water pipe does not have a retraction mechanism. If the water pipe is too long or too short, it will easily hinder the normal use of the water jet loom. Utility Model Content

[0005] The purpose of this invention is to provide a weft insertion water pipe for a water jet loom, so as to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a weft insertion water pipe for a water jet loom, comprising a water pipe body and a mounting frame. Connecting portions are fixedly installed at both ends of the water pipe body. A groove is formed on the outer side of each connecting portion. A rubber sleeve is fitted onto the inner side of each connecting portion. A retaining ring is fitted onto the outer side of each connecting portion. A retaining block is fixedly installed on the inner side of the retaining ring. A connecting sleeve is fitted onto the outer side of the water pipe body. A positioning ring is fixedly installed on the inner side of the connecting sleeve. A guide rod is fixedly installed on the inner side of the mounting frame. A bidirectional lead screw is rotatably installed on the inner side of the mounting frame. A knob is rotatably installed at the upper end of the mounting frame. A movable frame is movably installed on the outer side of the guide rod. A fixed roller is fixedly installed on the inner side of the movable frame.

[0008] Preferably, the inner diameter of the connecting part is larger than the inner diameter of the water pipe body, and the rubber sleeve fits against the outer side of the opening of the connecting part.

[0009] The above technical solution improves the sealing performance of water pipe connections with rubber sleeves.

[0010] Preferably, the slot is an annular structure, the retaining ring is a semi-circular structure, two retaining rings are symmetrically arranged, and the retaining block fits against the inner side of the slot.

[0011] With the above technical solution, the retaining ring is fitted on the outside of the connecting part, and the retaining block positions the retaining ring through the retaining groove.

[0012] Preferably, the inner side of the connecting sleeve is respectively fitted to the outer side of the rubber sleeve and the retaining ring, and the positioning ring is fitted to the retaining ring.

[0013] With the above technical solution, the connecting sleeve slides along the outside of the water pipe body, and the connecting sleeve plays a positioning role for the two retaining rings.

[0014] Preferably, there are two mounting brackets symmetrically arranged, four guide rods symmetrically arranged, two bidirectional lead screws symmetrically arranged, and the knob is fixedly connected to the bidirectional lead screw.

[0015] Through the above technical solution, the guide rod guides the movable frame. When the knob is turned, the double-acting screw rotates accordingly, and the double-acting screw drives the two movable frames to move in opposite directions.

[0016] Preferably, two movable frames are symmetrically arranged, and the movable frames are threaded to the outer side of the bidirectional lead screw. Two fixed rollers are respectively arranged on the inner side of the movable frames, and the water pipe body is wound around the outer side of the fixed rollers.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The weft insertion water pipe for water jet looms has two ends connected to the nozzle and water pump respectively through connecting sleeves. In use, two retaining rings are put on the outside of both ends of the water pipe, and the retaining blocks on the inside use the retaining grooves to position the retaining rings. The connecting sleeve is then put on the outside of the retaining rings to prevent the connecting sleeve from separating from the water pipe body. Rubber sleeves are put on the inside of both ends of the water pipe to improve the sealing of the connection and prevent leakage. Compared with traditional weft insertion water pipes, it is easier and faster to assemble. The water pipe body is wound on two movable frames. The spacing of the movable frames can be adjusted by turning the knob, which can play the function of retracting and extending the water pipe and prevent the water pipe from being too long or too short.

[0025] 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.

[0026] Example 1:

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a weft insertion water pipe for a water jet loom, including a water pipe body 1 and a mounting frame 2. Connecting parts 3 are fixedly installed at both ends of the water pipe body 1. A slot 4 is opened on the outer side of the connecting part 3. A rubber sleeve 5 is sleeved on the inner side of the connecting part 3. A retaining ring 6 is sleeved on the outer side of the connecting part 3. A retaining block 7 is fixedly installed on the inner side of the retaining ring 6. A connecting sleeve 8 is sleeved on the outer side of the water pipe body 1. A positioning ring 9 is fixedly installed on the inner side of the connecting sleeve 8. A guide rod 10 is fixedly installed on the inner side of the mounting frame 2. A bidirectional lead screw 11 is rotatably installed on the inner side of the mounting frame 2. A knob 12 is rotatably installed on the upper end of the mounting frame 2. A movable frame 13 is movably installed on the outer side of the guide rod 10. A fixed roller 14 is fixedly installed on the inner side of the movable frame 13.

[0028] Specifically, the inner diameter of the connecting part 3 is larger than the inner diameter of the water pipe body 1, and the rubber sleeve 5 fits snugly against the outer side of the opening of the connecting part 3. The advantage is that the rubber sleeve 5 improves the sealing performance of the water pipe connection.

[0029] Specifically, the slot 4 is a ring structure, and the retaining ring 6 is a semi-circular ring structure. Two retaining rings 6 are symmetrically arranged, and the retaining block 7 fits against the inner side of the slot 4. The advantage is that the retaining ring 6 is fitted on the outer side of the connecting part 3, and the retaining block 7 plays a positioning role for the retaining ring 6 through the slot 4.

[0030] Specifically, the inner side of the connecting sleeve 8 is respectively fitted with the outer side of the rubber sleeve 5 and the retaining ring 6, and the positioning ring 9 is fitted with the retaining ring 6. The advantage is that the connecting sleeve 8 slides along the outer side of the water pipe body 1, and the connecting sleeve 8 plays a positioning role for the two retaining rings 6.

[0031] Example 2:

[0032] like Figure 1-3 As shown, this is an improvement on the previous embodiment. Specifically, there are two symmetrically arranged mounting brackets 2, four symmetrically arranged guide rods 10, and two symmetrically arranged bidirectional lead screws 11. The knob 12 is fixedly connected to the bidirectional lead screw 11. The advantage is that the guide rods 10 guide the movable brackets 13, and when the knob 12 is rotated, the bidirectional lead screw 11 rotates accordingly, causing the two movable brackets 13 to move in opposite directions.

[0033] Specifically, there are two symmetrically arranged movable frames 13. The movable frames 13 are threadedly connected to the outer side of the bidirectional lead screw 11. Two fixed rollers 14 are respectively arranged on the inner side of the movable frames 13. The water pipe body 1 is wound around the outer side of the fixed rollers 14. The advantage is that the fixed rollers 14 guide the water pipe body 1. The fixed rollers 14 move with the movable frames 13 and drive the water pipe body 1 to extend and retract.

[0034] Working principle: First, the mounting bracket 2 is bolted onto the water jet loom. Rubber sleeves 5 are placed inside the connecting part 3, with the two rubber sleeves 5 aligned with the water nozzle and water pump respectively. Then, two retaining rings 6 are placed outside the connecting part 3, and the retaining block 7 is fitted against the inner side of the retaining groove 4. Next, the connecting sleeve 8 is slid to the outside of the retaining rings 6 and rotated to install at the interface between the water nozzle and water pump. The connecting sleeve 8 positions the retaining rings 6, preventing the rubber sleeves 5 and retaining rings 6 from separating from the connecting part 3. The rubber sleeves 5 improve the sealing of the water pipe connection. When the water pipe body 1 needs to be replaced, the connecting sleeve 8 is rotated in the reverse direction, and the water pipe body 1 is reconnected to the water nozzle and water pump. The pump separation design, compared to traditional weft insertion water pipes, facilitates the replacement of the connection end and the water pipe. When the length of the water pipe body 1 is insufficient, rotating the knob 12 guides the guide rod 10 to guide the movable frame 13. The bidirectional lead screw 11 rotates with the knob 12, driving the two movable frames 13 to move closer to each other. The fixed roller 14 moves with the movable frame 13, allowing both ends of the water pipe body 1 to be stretched outward. When the length of the water pipe body 1 is too long, rotating the knob 12 in the opposite direction causes the two movable frames 13 to move in opposite directions, causing both ends of the water pipe body 1 to retract inward. This prevents excessive exposure of the water pipe body 1 to the outside, thus serving the function of reeling in and unloading the line.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
