Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an air pressure detection device for air jet looms. Background Art

[0002] Air jet looms are shuttleless looms that use jets of air to pull the weft yarn through the shed. The operating principle is that air is used as the weft insertion medium, with the compressed air jet generating frictional traction on the weft yarn, pulling it through the shed. The jet flow creates a flow that inserts the weft. Air pressure testing on existing air jet looms typically measures the pressure at the air holes within the loom itself. During machine setup and mid-machine adjustments, a handheld pressure gauge is used to measure the pressure at each air hole. Each air jet loom undergoes approximately thirty tests per day.

[0003] After searching: An air pressure detection device for an air jet loom with authorization announcement numbers CN210863027U and CN218381386U still has some shortcomings during use. The size of the detection air pipe is relatively fixed, which makes it inconvenient to connect and use air measuring holes of different sizes on the air jet loom, reducing the versatility of the device. It is also inconvenient to adjust the angle of the detection air pipe, which reduces the effect of use. Therefore, we propose an air pressure detection device for an air jet loom to solve the above problems. Utility Model Content

[0020] The present invention is further configured as follows: the rotating shaft is located in front of the hose.

[0021] By adopting the above technical solution, the rotating shaft and the hose do not interfere with each other.

[0022] The beneficial effects of the utility model are:

[0023] 1. The utility model rotates the rotating shaft and the two upper bevel gears, and the two upper bevel gears drive the synchronous rotation of the two lower bevel gears and the threaded rod. Under the guidance of the slider and the slide groove, the two threaded rods drive the two movable plates and the rack to move up or down, and the rack drives the gear to rotate counterclockwise or clockwise. The gear drives the deflection of the rotating shaft, the rotating plate, the main pipeline and the detection air pipe, and then the inclination angle of the detection air pipe can be adjusted to align it with the air measuring hole for later insertion and connection.

[0024] 2. The utility model starts two cylinders, which drive the main pipeline and multiple detection air pipes to move downward. The detection air pipes drive the ladder-shaped platform and the rubber sealing gasket to move downward. Since the diameters of the ladder-shaped platform and the rubber sealing gasket are arranged to be smaller at the bottom and larger at the top, when moving downward, the ladder-shaped platform and the rubber sealing gasket can be sealed and connected to the air measuring holes of different diameters, which not only improves the versatility of the device, but also ensures the sealing of the connection, avoiding air leakage and affecting the accuracy of air pressure detection.
