Description

Safety alarm device for flat knitting machine

Technical field

The present invention relates to the flat machine technical field, the safety alarm device for flat knitting machine of using when particularly relating to flat machine braiding garment piece.

Background technology

The safety alarm device that uses on the straight-bar machines, be probe unit, when machine carried out the garment piece knitting, probe unit floated, flies abnormal conditions such as yarn and foreign material obstruction and carries out security alarm to yarn, thereby can avoid braided fabric breakage or other failure condition of machine to take place.Modal probe unit in the present straight-bar machines field; its probe tile is the type of swinging; when head moves; probe unit is only reported to the police to the unusual yarn and the foreign material on its front (i.e. a left side or right); because probe tile can only swing; so can not detect to the unusual float of its vertical direction and foreign material etc.; thereby also just can not report to the police; this has just influenced the weave effect of fabric and the serviceability of machine greatly; for this reason; the invention provides a kind of novel probe safety alarm device; probe tile not only can swing during this device work; but also can swing up and down, fabric and machine are all played a very good protection, improved the service life of the weaving quality and the machine of fabric greatly.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of probe both can vacillate now to the left, now to the right, and the safety alarm device for flat knitting machine that can teeter again, it has the function of multi-faceted detection.

For solving the problems of the technologies described above, the technical solution used in the present invention is: safety alarm device for flat knitting machine, be arranged on an end of close needle-bar on the head, comprise probe, probe base and microswitch, probe is connected on the probe base, match with the microswitch on being fixed on probe base, it is characterized in that: it also comprises probe carriage, probe is rotatably connected on the front of probe carriage by pivot pin, the side of probe carriage is rotatably connected on the probe base by rotating shaft, axially axially mutual vertical with pivot pin of described rotating shaft.

The lower end of probe carriage is provided with fluting, and rotating shaft is horizontally through fluting and is rotatably connected on the probe base, is socketed with torsion spring in the rotating shaft, and this torsion spring main body is positioned at fluting, and the torsion spring two ends are fixed on the probe base.

As a further improvement on the present invention, probe carriage is provided with an aperture, is provided with spring in the aperture, and a ball is set on the spring, and the part of ball is exposed aperture; Probe is provided with the draw-in groove that matches with ball, and the ball exposed portions serve engages with draw-in groove on the probe.Probe cannot arbitrarily be swung on probe carriage like this, has only probe just can swing under situation stressed on the left and right direction, promptly just swings when probe is run into unusual yarn or foreign material on left and right direction.

Microswitch is fixed on the probe base by the microswitch frame, and the contact of microswitch contacts with the tail end of probe.

Probe body is a flat, and its head side is Z-shaped step-like, and the bending angle of this head first bending place is the 120-150 degree, and the bending angle of this head second bending place is the 100-140 degree.This step-like end of probe plays certain effect of dodging to the yarn mouth, guarantees yarn mouth operate as normal, makes safety alarm device work more stable.

Probe is rotatably connected on the probe carriage front by pivot pin, can left and rightly swing, when the probe and arranged on left and right sides had unusual yarn or foreign material, probe touched yarn or foreign material and left and right waving, this moment, probe tail end and microswitch broke away from, and microswitch just carries out security alarm like this.

The probe carriage lower end is provided with fluting, and torsion spring is installed in the fluting, and a rotating shaft is horizontally through this fluting from the probe carriage side, torsion spring set is connected on the rotating shaft middle part, the two ends of torsion spring are fixed on the probe base, and are spacing by torsion spring when probe carriage is rotatably connected on the probe base like this, can at will not rotate.When the probe upper and lower upwards had unusual yarn or foreign material, probe was because of touching the upper and lower swing of yarn or foreign material, and this moment, probe tail end and microswitch broke away from, and microswitch just carries out security alarm like this.

The present invention places the needle-bar mouth place on the head; unusual yarn or foreign material on both can the left and right direction of detector probe; realize the security alarm on the left and right direction; the unusual yarn or the foreign material that again can the detector probe upper and lower make progress; realize the security alarm that upper and lower makes progress; thereby realized multi-faceted security alarm, fabric and machine have been played the better protection effect, improved the service life of the weaving quality and the machine of fabric greatly.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, probe base 1 upper end is equipped with microswitch seat 2, and microswitch 3 is fixed on the microswitch seat 2, places the front of probe base 1, and the contact 3a on the microswitch is towards the positive 1a of probe base.The side of probe base is provided with two spacer pins, i.e. the first spacer pin 7a and the second spacer pin 7b.

Probe carriage 5 lower ends are provided with a fluting 5c, and a torsion spring 8 is installed in this fluting 5c, and rotating shaft 6 is passed this torsion spring 8 probe carriage 5 is rotatably connected on probe base 1 lower end side.The two ends of torsion spring 8 are fixed on the probe base by the first spacer pin 7a and the second spacer pin 7b.The probe carriage 5 upper and lower swing of probe base relatively like this, promptly prolong Z, the swing of T direction, because the position-limiting action of torsion spring, probe carriage can at will not swung, have only probe to make progress at upper and lower and just can swing when stressed, both probe was just swung when upper and lower is upwards run into unusual yarn or foreign material.

Probe carriage 5 upper ends are provided with an installing hole, and this installing hole cooperates the through hole 4b of the probe afterbody that is rotationally connected with pivot pin 12, and probe probe carriage relatively turns left and right, and promptly rotate along X, Y direction.The tail end 4a of probe contacts with the contact 3a of microswitch, also is provided with a draw-in groove 4c below the probe through hole.

As Fig. 4, shown in Figure 5, end of probe 4d front is oval heart-shaped, its side is Z-shaped step-like, the radian of the end of probe first bending place 4d1 is 120 degree, the radian of the end of probe second bending place 4d2 is 110 degree, this step-like structure plays certain effect of dodging to the yarn mouth, guarantees yarn mouth operate as normal.

As shown in Figure 1, an aperture 5b also is set below the installing hole on the probe carriage 5, holding screw 11, spring 9 and steel ball 10 are set in this aperture 5b, holding screw 11 blocks aperture 5b away from an end of probe, spring 9 is between holding screw 11 and steel ball 10, spring 9 is released aperture 5b with three of steel ball a 10/part and is engaged with draw-in groove 4c on the probe, probe can arbitrarily not swung like this, have only probe on left and right direction, just can swing when stressed, just swing when both probe is run into unusual yarn or foreign material on left and right direction.

When probe touches unusual yarn or foreign material on left and right direction, the just left and right swing of probe, promptly along X, the swing of Y direction, this moment, the contact of probe tail end and microswitch broke away from, and microswitch is connected circuit and is carried out security alarm; When probe when upper and lower upwards touches unusual yarn or foreign material, probe and probe carriage on the whole, lower swing, promptly along the swing of Z, T direction, this moment, the probe tail end broke away from the contact of microswitch, microswitch connection circuit carries out security alarm.
