Description

A kind of feed carrier of flat machine

Technical field

The utility model relates to the textile machine apparatus field, particularly a kind of feed carrier of flat machine.

Background technology

Flat machine is very strict to the requirement of yarn; If the yarn knotting or the group of being twisted into, the lighter cause textiles situation such as cavity, wire jumper to occur, weight person destroys the weaving parts of flat machine; Therefore; Yarn enters into the process of flat machine weaving parts from yarn coil, need dredge processing to yarn, to avoid the problem of the yarn knotting or the group of being twisted into.

In the prior art, the feed carrier of flat machine is arranged at the upper end of body, comprises feeder seat, and is installed on guide pulley and yarn guide on the feeder seat.When flat machine was opened and begun to weave, the yarn on the yarn coil is process from the guide pulley earlier, entered into the yarn guiding ring of yarn guide again, entered into the weaving parts of weaving loom at last, accomplished the guide process.Yet; Though this feed carrier can avoid yarn before entering into the weaving parts, to tie a knot or the group of being twisted into; But when there was the situation of the knotting or the group of being twisted in yarn itself, this feed carrier but can not stop the yarn of the knotting or the group of being twisted into to enter into the weaving parts of flat machine.

The utility model content

The technical problem that the utility model will solve is to above-mentioned deficiency of the prior art; A kind of feed carrier of flat machine is provided; This feed carrier exists under the situation of the knotting or the group of being twisted at yarn itself, can in time stop the operation of flat machine, and in time make warning.

The technical scheme of the utility model is: a kind of feed carrier of flat machine; Comprise feeder seat, guide pulley and yarn guide, said guide pulley is installed on an end of feeder seat, and yarn guide is installed on the other end of feeder seat; Yarn can enter into flat machine inside through guide pulley, yarn guide successively; It is characterized in that: be provided with guide plate and metal tommy bar between said guide pulley and the yarn guide, this guide plate is installed on the feeder seat lower end, and the upper end of this metal tommy bar is articulated in the feeder seat versatilely; The lower end edge guide plate plate of metal tommy bar faces down and stretches out, and the slit that forms between guide plate and the metal tommy bar only holds a yarn and slides through; This metal tommy bar is provided with the Metal Contact pin near a side of yarn guide, and the metal tommy bar can be contacted with this Metal Contact pin after pulling; Short-circuit sensor and alarm lamp also are installed in this feeder seat; The signal input part of short-circuit sensor is electrically connected with metal tommy bar and Metal Contact pin respectively, and the signal output part of short-circuit sensor is electrically connected with alarm lamp and the inner control end of flat machine respectively.

One end of said yarn guide is fixedly connected with feeder seat, and the other end of yarn guide is provided with yarn guiding ring, and yarn can pass in yarn guiding ring.

Fix with screw between said guide plate and the feeder seat, the guide pulley is installed on the guide plate.

The beneficial effect of the utility model is: owing to be provided with guide plate and metal tommy bar between guide pulley and the yarn guide; And the slit that forms between guide plate and the metal tommy bar only holds a yarn and slides through; Therefore; When there was the situation of the knotting or the group of being twisted in yarn itself, the tieing of yarn just can't pass through from the slit between guide plate and the metal tommy bar swimmingly; Again because the metal tommy bar is provided with the Metal Contact pin near a side of yarn guide; Simultaneously, short-circuit sensor and alarm lamp are installed also in the feeder seat, the signal input part of short-circuit sensor is electrically connected with metal tommy bar and Metal Contact pin respectively; The signal output part of short-circuit sensor is electrically connected with alarm lamp and the inner control end of flat machine respectively; Therefore, the knot of yarn is run into will promote metal tommy bar contacting metal contact pin after the metal tommy bar, and after short-circuit sensor detects the signal of metal tommy bar and the electric short circuit of Metal Contact pin; Send alarm signal to alarm lamp and the inner control end of flat machine immediately; Make alarm lamp send warning, make the inner control end of flat machine make shutdown control simultaneously, thereby make the utility model exist under the situation of the knotting or the group of being twisted at yarn itself according to this alarm signal; Can in time stop the operation of flat machine, and in time make warning.
