Description

Technical Field

[0001] This utility model relates to the technical field of air-jet loom components, specifically to a fixing device for an auxiliary nozzle. Background Technology

[0002] In air-jet looms, the auxiliary nozzle is a key component used to assist in weft yarn feeding. In existing technology, the auxiliary nozzle is typically installed as a component. Due to the large size of the component, it is usually placed outside the slot, and then secured with screws inserted into the slot. The reed is then fixed to the reed seat by a reed seat pressure strip. This means the auxiliary nozzle is usually tilted towards the reed, with its air nozzle close to the lower side of the reed's airflow channel. Consequently, when adjusting the position of the air nozzle relative to the airflow channel, the auxiliary nozzle can only be tilted and extended, making it impossible to accurately position the air nozzle under the airflow channel. This results in significant airflow pressure loss, affecting weft yarn tension control, and also leads to low installation accuracy and inconvenient disassembly and maintenance.

[0003] Therefore, it is necessary to provide a new technical solution. Utility Model Content

[0004] The present invention aims to provide a fixing device for an auxiliary nozzle, so as to solve the problems of low installation accuracy, inaccurate distance adjustment, poor airflow transmission efficiency, and inconvenient maintenance of the auxiliary nozzle in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for fixing an auxiliary nozzle, comprising:

[0007] The reed base has a strip-shaped slot with a lateral opening on one side, and the top of the slot has a mounting hole that passes through the slot and the reed base.

[0008] A steel reed, the bottom of which is fixed to the reed base, and the top of which extends outward perpendicularly to the reed base;

[0009] An auxiliary nozzle is disposed in the mounting hole;

[0010] A locking block, which is engaged within the locking slot, is provided with a threaded hole; and

[0011] A set screw, which passes through a threaded hole on the locking block, abuts against the auxiliary nozzle to lock the auxiliary nozzle into the mounting hole.

[0012] Furthermore, the mounting hole is parallel to the reed, and the auxiliary nozzle is parallel to and close to the reed.

[0013] Furthermore, the top of the auxiliary nozzle extends from the top of the mounting hole and abuts against the reed, while the bottom of the auxiliary nozzle extends from the bottom of the mounting hole and is connected to an external air valve via a pipe.

[0014] Furthermore, the slot opening is a wedge shape that is narrower on the outside and wider on the inside, and the widest part of the card block is greater than the narrowest part of the slot opening, thereby securing the card block to the slot opening.

[0015] Furthermore, the card block is a wedge shape that matches and fits the shape of the slot.

[0016] This utility model has the following beneficial effects:

[0017] 1. The auxiliary nozzle is positioned by the precision-machined mounting holes on the reed base, which improves the positional accuracy of the nozzle and the consistency of the spray angle. The auxiliary nozzle is parallel to the reed, and the distance between the auxiliary nozzle and the reed is not affected when the auxiliary nozzle is adjusted back and forth.

[0018] 2. The auxiliary nozzle is closer to the weft channel of the reed, resulting in more stable airflow and promoting energy conservation and consumption reduction;

[0019] 3. The wedge-shaped locking block and set screw are used for secure installation and easy disassembly and maintenance;

[0020] 4. It has a simple structure, low manufacturing cost, and is suitable for large-scale production and application.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
