Description

TECHNICAL FIELD

[0001] The utility model belongs to textile machinery technical field, especially relate to a novel air gun for threading bus duct. BACKGROUND

[0002] In the textile industry, the threading of busbars (usually referring to continuous wires or rails used to connect multiple working components) is a common maintenance procedure, especially in large spinning workshops. With the development of technology and the improvement of factory automation level, the requirement for production efficiency is also constantly increasing. However, in actual production, the frequent breakage or regular replacement of busbars poses a considerable challenge to the production line, especially when the busbars need to be rethreaded. The traditional method of busbar threading relies on manual operation, such as using a stainless steel ball chain to bind the head of the busbar and using external force (such as knocking) to promote the busbar to move forward along the duct. This method not only takes a long time, but also easily causes the busbar to jam or be damaged in the duct when facing complex curved paths, increasing the difficulty of maintenance. In addition, since the busbar material is usually soft and does not have enough rigidity to overcome the friction in the duct, this further increases the difficulty of threading.

[0003] With the expansion of factory scale and the progress of technology, this inefficient manual operation cannot meet the needs of modern production. In particular, on a production line with nine spinning machines, the number of busbars for each machine can reach dozens, totaling more than a hundred. If manual threading is used, not only is it time-consuming and labor-intensive, but it also affects the continuity and stability of production. Therefore, finding a fast, reliable, and efficient method for threading busbars has become a pressing problem. SUMMARY

[0006] Compared with the prior art, the utility model has the beneficial effects that by utilizing the "Venturi effect", the novel air gun can generate stable airflow, which is sufficient to push the soft busbar to move smoothly in curved ducts of different angles, thereby significantly improving the threading speed. At the same time, by precisely controlling the pressure of the airflow, the phenomenon of busbar twisting or loosening caused by excessive airflow is avoided, and the busbar is also prevented from being damaged during threading, thereby improving the service life of the busbar. Moreover, the air gun proposed in the present application can adapt to various angle curved ducts on site, solving the problem of difficulty in passing through 90-degree angles in traditional methods, making the threading of busbars more flexible and convenient.

[0007] The new air gun has a busbar suction inlet with an outer diameter of 15-25 mm.

[0008] The new air gun has a handle fixed to the gun body by a fastener.

[0009] The new air gun has a control valve with a control member rotatably connected to the control valve, and the size of the air flow is adjusted by rotating the control member.

[0010] The new air gun has a narrow throat with a diameter of 3-7 mm.

[0011] The new air gun has a gun body and a nozzle that can be integrally formed.

[0012] The new air gun has a gun body and a handle made of lightweight materials.

[0013] The new air gun further includes a safety locking device located in the handle.

[0020] Further, in a pipe or other fluid passage, when fluid flows through a narrow section, the velocity of the fluid increases because the fluid must pass through a smaller cross-sectional area in the same amount of time, resulting in an increase in flow rate. According to Bernoulli's principle, an increase in the velocity of a fluid results in a decrease in its static pressure. This means that the pressure is lower at the narrow part of the pipe than at the wider part of the pipe. This principle has applications in many places, such as in the design of nozzles 200, Venturi flow meters for measuring fluid flow, and in some cases to generate a vacuum. Of course, the specific connection method of the nozzle 200 and the barrel 100 is not limited in the present application, preferably, the barrel 100 and the nozzle 200 can be integrally formed, not only can enhance the structural strength of the entire air gun, reduce the joint between the barrel 100 and the nozzle 200, but also improve the air tightness of the entire air gun, avoid the problem of air leakage caused by improper connection, ensure the air tightness of the air path system 300, so that the compressed air can pass through the nozzle 200 more efficiently to generate the required Venturi effect. Therefore, the new air gun mentioned in the present application is to use the high-speed airflow generated by the Venturi effect to push the bus through the guide pipe, so as to improve the threading efficiency. By designing appropriate flow channel shape, it can ensure that the airflow accelerates in a specific area to form enough power to move the bus, and at the same time, it can also control the size of the airflow to avoid the phenomenon of opening or twisting of the bus during threading. Specifically, referring to Fig. 1 , the bottom of the handle 400 of the air gun is provided with an air inlet connection port, the air inlet port can be connected with the external air pipe to input the compressed gas into the air gun, of course, the specific structure and shape of the air inlet connection port are not limited in the present application, referring to Fig. 2 , the compressed gas enters through the air inlet connection port at the handle 400 and enters the inside of the barrel 100 through the air outlet at the top of the handle 400, the compressed gas passes through the air path system 300, specifically, when the compressed gas passes through the narrow throat 330, the air path system 300 will generate a Venturi effect, forming a high-speed airflow to suck the bus into the air gun, avoiding the reverse airflow of the guide pipe. Of course, the specific diameter of the narrow throat 330 is not limited in the present application, preferably, the diameter of the narrow throat 330 is 3mm-7mm. At the same time, the guide pipe inlet matched with the air gun proposed in the present application is connected, specifically, the outlet of the nozzle 200 is tightly attached to the inlet of the guide pipe, so that the bus can complete the threading under the action of high-speed airflow. In order to meet the needs of bus threading in different occasions, the new air gun provided by the present application also includes guide pipe interfaces of different sizes to adapt to the needs of bus threading in different occasions. Different sizes of guide pipe interfaces make the air gun adapt to various specifications of bus guide pipes, whether during overhaul or during regular production, the bus threading work can be quickly and effectively carried out. By replacing guide pipe interfaces of different sizes, the operator can choose the most suitable interface size according to actual needs, so that the threading task can be successfully completed when facing bus of different diameters or guide pipe of different bending angles.

[0021] Further, the application does not limit the specific diameter of the busbar suction port 110, in order to prevent the busbar suction port 110 from being too small, the busbar cannot be smoothly sucked into the air gun, resulting in the line at the busbar suction port 110 being blocked or twisted, the outer diameter of the busbar suction port 110 is 15mm-25mm, of course, the utility model does not limit the connection mode of the busbar suction port 110 and the gun body 100, preferably, the busbar suction port 110 can be movably connected to the gun body 100. Of course, the busbar suction port 110 can also be integrally formed with the gun body 100. Further, the utility model does not limit the specific connection mode of the handle 400 and the gun body 100, preferably, the handle 400 is fixed on the gun body 100 through the fastener 410. Of course, the handle 400 and the gun body 100 can also be integrally formed.
