Description

Technical Field

[0001] This utility model belongs to the field of textile machinery, specifically relating to a quick-release structure for air racks that improves the collection efficiency of ring spinning machines. Background Technology

[0002] Currently, when inflating the air frame of a ring spinning machine, the air source at the head or tail of the machine is introduced into the air frame through a solenoid valve and air pipe. When deflating the air frame, the gas inside is also released to the head or tail of the machine through an air pipe, and then slowly discharged through a solenoid valve and muffler at the head or tail of the machine. However, with the popularization of long doffing machines and the increase in the number of spindles in ring spinning machines, the length of the air frame is also getting longer and longer. The exhaust time of the traditional solenoid valve muffler is getting longer and longer, and the doffing efficiency is significantly reduced, which in turn leads to a decrease in the production efficiency of the ring spinning machine. Utility Model Content

[0003] The purpose of this invention is to provide an air rack venting and quick-release structure that improves the collection efficiency of ring spinning machines, thereby increasing the production efficiency of the spinning machines.

[0004] The technical solution of this utility model is as follows: an air rack venting and quick-release structure for improving the collection efficiency of a ring spinning frame, located at the end of the air rack, wherein the air rack is hollow inside and located on both sides of the frame of the spinning frame, the frame including several middle wall plates, and air rack assemblies on both sides of the frame, each air rack assembly consisting of several sequentially connected air rack sections, and a number of tube grippers evenly distributed on the air rack assembly, each tube gripper having an air bladder, and the air bladders communicating with the air rack assembly, thereby improving the air collection efficiency of each side of the ring spinning frame. Each end of the frame assembly is equipped with a quick-release air rack structure. Each quick-release air rack structure includes an air rack pipe connector and a quick-release valve. The air rack pipe connector is located at the end of the air rack and is connected to the air rack. One side of the air rack pipe connector is connected to the quick-release valve. The quick-release valve is T-shaped and includes a connecting part, an inflation part, and an exhaust part. The connecting part is connected to the air rack pipe connector, and the inflation part is connected to an air pipe. The air pipe is connected to the inflation device at the head or tail of the ring spinning machine.

[0005] Furthermore, the series of the quick exhaust valve is ASV.

[0006] Furthermore, the gas frame pipe connector is connected to the gas frame by screws, and the gas frame pipe connector is threadedly connected to the connection part of the quick exhaust valve.

[0007] The beneficial effects of this utility model are as follows: the gas in the air bladder and air frame of the tube gripper is directly discharged to the external environment through the quick exhaust valve, without the need to discharge the gas from the solenoid valve and muffler at the head or tail of the spinning machine through the air pipe. This reduces the time consumed by the gas release in the air bladder and air frame of the tube gripper, thereby speeding up the release speed of the spinning tube by the tube gripper during the spinning machine assembly process, thus increasing the assembly efficiency of the spinning machine and accelerating the production efficiency of the ring spinning machine.

The two screw drive devices 31 are respectively located on both sides of the middle wall plate 11, and both screw drive devices 31 are located at the rear of the ring spinning machine. Each screw drive device 31 has a drive mechanism connected to its screw. Pipe 33; Both sides of the middle wall panel 11 are provided with several swing seat couplings 34. Each swing seat coupling 34 includes a swing shaft, an outer swing seat 34-1, and a swing shaft seat. The swing shaft is sleeved on the outside of the transmission pipe 33, and the swing shaft and the transmission pipe 33 can slide and rotate relative to each other. Each swing shaft is sleeved on the outside of an outer swing seat 34-1, and each outer swing seat 34-1 is provided with a swing shaft seat. The bottom end of each swing shaft seat is supported on the ground. Each transmission pipe is connected to several lifting components 32.

[0016] With the increasing prevalence of long doffing machines and the increasing number of spindles in ring spinning frames, the air rack 12 is also becoming longer. The gas inside the air rack 12 is discharged through the air pipe via the solenoid valve and muffler at the head or tail of the ring spinning frame. The exhaust time is getting longer and longer, which leads to a decrease in the doffing efficiency of the ring spinning frame, and thus a decrease in the production efficiency of the ring spinning frame. In view of this, the inventors of this application provide an air rack venting and quick exhaust structure to improve the doffing efficiency of the ring spinning frame, which can improve the doffing efficiency of the ring spinning frame and thus accelerate the production efficiency of the ring spinning frame.

[0017] like Figures 1 to 4As shown, an air rack venting and quick-release structure for improving the collection efficiency of a ring spinning frame is provided at the end of an air rack 12. The air rack 12 is hollow inside and is located on both sides of the frame 1 of the spinning frame. The frame 1 includes several middle wall plates 11. Air rack assemblies are provided on both sides of the frame 1. Each air rack assembly is composed of several air racks 12 connected in sequence. Several tube grippers 13 are evenly provided on the air rack 12. Each tube gripper 13 is equipped with an air bladder. The air bladders are all connected to the air rack 12. The ends of the air rack assemblies on each side of the ring spinning frame are... The air frame is equipped with a quick-release air structure. Each quick-release air structure includes an air frame pipe joint 5 and a quick-release valve 2. The air frame pipe joint 5 is located at the end of the air frame 12 and is connected to the air frame 12. One side of the air frame pipe joint 5 is connected to the quick-release valve 2. The quick-release valve 2 is T-shaped and includes a connecting part 21, an inflation part 22 and an exhaust part 23. The connecting part 21 is connected to the air frame pipe joint 5. The inflation part 22 is connected to an air pipe, which is connected to the inflation device at the head or tail of the ring spinning machine.

[0018] Among them, the series of quick exhaust valve 2 is ASV.

[0019] Specifically, the gas frame pipe connector 5 is connected to the gas frame 12 by screws, and the gas frame pipe connector 5 is threadedly connected to the connection part 21 of the quick exhaust valve 2.

[0020] Based on the above embodiments, when it is necessary to inflate the air frame 12, the inflator at the head or tail of the ring spinning machine will introduce compressed air into the interior of the air frame 12 through the air pipe from the inflator 22 of the quick exhaust valve 2 and the air frame pipe joint 5; when the gas in the air frame 12 is discharged, the gas in the air frame 12 will be discharged from the exhaust section 23 of the quick exhaust valve 2 through the air frame pipe joint 5.

[0021] The working principle of this utility model is as follows: the initial state is as follows: Figure 1As shown, the air frame 12 is located in the middle of the middle wall plate 11. The air inflation device at the head or tail of the spinning machine introduces compressed air into the air frame 12 through the air pipe from the inflation part 22 of the quick exhaust valve 2 and the air frame pipe joint 5. The gas inside the air frame 12 enters the air bladder of the tube gripper 13. After the air bladder is inflated, it squeezes the spinning tube on the spinning machine. The output end of the push cylinder 41 in the swing mechanism 4 extends, and the push cylinder 41 drives the transmission shaft 43 to move. The transmission shaft 43 pulls one end of the swing arm assembly 44 connected to it to move, so that the swing arm assembly 44 rotates around its connection with the middle wall plate 11. When the swing arm assembly 44 rotates, it lifts the swing arm 45 connected to one end. The swing arm 45 drives the outer swing seat 34-1 to rotate. The outer swing seat 34-1 drives the rotating short arm 36 connected to it to swing away from the middle wall plate 11. At the same time, the rotating short arm 36 swings, driving the rotating long arm 35 to swing, thereby driving the air frame 12 to move away from the middle wall plate 11. When the lifting assembly 32 and the air frame 12 swing to the designated position, the transmission tube 33 is moved by the screw transmission device 31. The transmission tube 33 drives the rotating long arm 35 to move. The angle between the rotating long arm 35 and the rotating short arm 36 gradually increases. The air frame 12 at the end of the rotating long arm 35 gradually descends. At this time, the spinning tube squeezed by the air bladder inside the tube gripper 13 set on the air frame 12 moves downward along with the air frame 12. When the air frame 12 moves to the designated position, the output end of the push cylinder 41 is shortened. The push cylinder 41 drives the transmission shaft 43 to move. The swing arm assembly 44 connected to the transmission shaft 43 rotates around its connection with the middle wall plate 11. When the swing arm assembly 44 rotates, it presses down the swing arm 45. The swing arm 45 drives the outer swing seat 34-1 to rotate. The outer swing seat 34-1 drives the rotating short arm 36 connected to it to swing towards the middle wall plate 11, thereby driving the rotating long arm 35 and the air frame 12 to move towards the middle wall plate 11.

[0022] When the air frame 12, the tube holder 13, and the spinning tube swing to the designated position, the gas in the air bladder of the tube holder 13 and the gas in the air frame 12 are directly discharged to the outside air through the exhaust section 23 of the quick exhaust valve 2. It is not necessary to discharge the gas through the solenoid valve and muffler at the head or tail of the spinning machine via an air pipe, which speeds up the gas discharge. After the gas in the air bladder of the tube holder 13 is discharged, the air bladder is no longer restricting the spinning tube. The spinning tube falls onto the cam below the spinning machine under the action of gravity, completing the tube release action in the ring spinning machine's settling process. The time consumed by the gas release in the air bladder of the tube holder 13 and the air frame 12 is reduced, which speeds up the settling efficiency of the spinning machine and thus speeds up the production efficiency of the ring spinning machine.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
