Description
Technical Field
The utility model relates to the technical field of air jet looms, in particular to a stop weft yarn buffer protection device of an air jet loom.
Background
The original air jet loom with air supply device is a piston air compressor which adopts synchronous belt and other modes to realize mechanical synchronization with the operation of the loom, the piston air compressor is directly connected with a main jet weft insertion system of the air jet loom by an air supply pipe, when the loom normally operates, the piston air compressor supplies air to the main jet weft insertion system uninterruptedly so as to ensure smooth weft insertion process, when detecting that the faults such as broken ends of warp yarns or abnormal weft insertion and the like require stopping, the main electric control system of the loom immediately sends a stopping signal, after receiving the stopping signal, the weft accumulator immediately stops yarn supply, and the loom continues to rotate by a certain angle due to inertia, namely, a stopping braking process exists.
In this process, the piston air compressor, because it is mechanically synchronized with the operation of the loom, also has a compression stroke to continue to supply air to the main jet insertion system, since the weft accumulator has stopped supplying yarn, and this continued air supply causes the weft yarn to be blown off at the main nozzle position.
Disclosure of Invention
The utility model aims to solve the technical defects and provides a stop weft yarn buffer protection device of an air jet loom, which can prevent weft yarn from being blown off directly during stop braking.
The utility model discloses a parking weft yarn buffer protection device of an air-jet loom, which comprises a frame, wherein an electromagnet is horizontally arranged on the frame, a counterweight iron block is arranged at the upper end of the electromagnet, a first pulley is arranged in the middle of the upper end surface of the counterweight iron block, a second pulley is arranged on one side above the first pulley, a third pulley is arranged on the other side of the upper end surface of the counterweight iron block, the second pulley and the third pulley are connected with the frame through a connecting rod, and the device further comprises a main electric control system of the air-jet loom, wherein the electromagnet is electrically connected with the main electric control system of the air-jet loom.
When the scheme is used, weft yarns sequentially bypass the second pulley, the first pulley and the third pulley, when the air jet loom normally operates, the main electric control system of the air jet loom supplies power to the electromagnet, the electromagnet attracts the counterweight iron block, when faults such as broken ends of warp yarns or abnormal weft insertion and the like are detected to stop, the main electric control system of the air jet loom immediately sends a stop signal, after the stop signal is received, the weft accumulator immediately stops supplying yarns, and meanwhile, the main electric control system of the air jet loom controls the electromagnet to cut off, and at the moment, the piston air compressor continuously supplies air to the main weft injection system due to the fact that the piston air compressor is mechanically synchronous with the loom, the weft yarns upwards pull the first pulley and the counterweight iron block to play a buffering role for the weft yarns, so that the weft yarns are prevented from being blown off directly.
Further, no. two pulleys and No. three pulleys are symmetrically arranged about No. one pulley, two sides of the upper end face of the electromagnet are symmetrically provided with vertical upward guide rods about No. one pulley, guide holes are correspondingly formed in the counterweight iron blocks, the counterweight iron blocks are slidably arranged on the guide rods through the guide holes, and the counterweight iron blocks are more stable when the weft yarns upwards pull the No. one pulley and the counterweight iron blocks through the guide rods.
Further, the nearest distance between the edge of the second pulley and the edge of the third pulley is equal to the diameter of the first pulley, at this time, the weft yarn wound between the second pulley and the first pulley and the weft yarn wound between the third pulley and the first pulley are in vertical upward states, and when the counterweight iron block and the first pulley are pulled upwards, the force born by the weft yarn is relatively uniform.
The beneficial effects of the utility model are as follows: when detecting that the warp breaks ends or the weft insertion is abnormal and other faults need to be stopped, the main electric control system of the air jet loom immediately sends a stop signal, after receiving the stop signal, the weft accumulator immediately stops supplying yarns, and meanwhile, the main electric control system of the air jet loom controls the electromagnet to be powered off, and at the moment, the piston type air compressor is mechanically synchronous with the operation of the loom, so that a compression stroke exists to continuously supply air to the main weft injection system, and weft yarns can upwards pull a first pulley and a counterweight iron block to buffer the weft yarns, so that the weft yarns are prevented from being blown off directly.
