Negative shedding type jet loom heald frame depressing and positioning method

Abstract

The invention provides a lowering and positioning method of passive open-type air jet loom heald frame and a leveling positioning device, and aims to overcome the shortages in the prior art that a great amount of persons are needed, operation is in risk and people is likely to be injured when replacing parts such as open arms in the shedding cam box of the passive air jet loom. The device comprises a heald frame lowering and positioning device and a fixing device of the heald frame lowering and positioning device, wherein the fixing device is fixedly connected with the heald frame lowering and positioning device; the heald frame lowering and positioning device comprises a pressing device and an adjusting device for moving the pressing device up and down. The heald frame is pressed by first placing the heald frame on the leveling position and lowering and positioning the heald frame with the leveling and positioning device. By adopting the device and method, operators can be reduced and the operation is safe.

Description

[0001] This case is a divisional application with the application number 201310382668.2 and the patent titled "Depression and positioning method of heald frame of passive open air-jet loom and positioning device for flat heald". technical field [0002] The invention relates to a method for lowering and locating a heald frame, in particular to a method for lowering and locating a heald frame during shunting of a negative shedding air-jet loom. Background technique [0003] Passive shedding air-jet loom manufacturers and loom users often need to replace parts such as the shedding arm in the shedding cam box body or the wire rope for hoisting the heald frame in the production and maintenance process. In the existing operation, first use the leveling heald device to level the healds, and then two people need to go to the top of the loom and use the heald frame separator to press down the heald frame to loosen the steel wire rope hanging the heald frame, and then the heald frame ...

AI Technical Summary

Problems solved by technology

Using the above method and tools to press down the heald frame has the following disadvantages: 1. The spring in the heald box is easy to fall off, so it is necessary to remove the top cover and the plexiglass cover of the heald box in advance to bind the spring, so the work 2. It requires a lot of manpower and the operation is dangerous, which is easy to cause personal injury accidents

During this process, some looms have too small a gap between the return heald arms or the hook head of the heald frame separator is too wide, so that the hook head of the heald frame separator is easily stuck in the gap between the return heald arms and cannot rise. , it often occurs that the hook head will suddenly bounce after shaking the hook head back and forth, and the bounced position is just facing the operator's face. Due to the strong traction force of the spring, it will seriously hurt the operator's face
