Abstract

A yarn selecting device for an evenness tester is used for detecting slivers and yarns. A knob switch is mounted on an outer casing, a common contact of the knob switch and a contact I form a group of contacts serially connected with a detecting circuit I, the common contact and a contact II form another group of contacts serially connected with a detecting circuit II, and the knob switch rotating left and right can realize division and test of yarn passages a-b or yarn passages c-e. When the knob switch rotates leftwards, a detection circuit corresponding to the yarn passages a-b is switched on so that the yarn passages a-b can be tested, when the knob switch rotates rightwards, a detecting circuit corresponding to the yarn passages c-e is switched on so that the yarn passages c-e can be tested, and then the yarn passages can be divided conveniently. The yarn selecting device eliminates a slider and a micro-switch in the original mechanism, a slide plate is only utilized as a mechanism positioning device, the knob switch is additionally mounted on the side surface of the evenness tester, so that the yarn selecting device is flexible and reliable in detachment, convenient in operation and long in service life, and simultaneously, the switch is simple and convenient in replacement and free of adjustment.

Description

The dried instrument yarn of bar type selecting device

Technical field

The utility model relates to Textile Engineering detection technique field, the particularly a kind of dried instrument yarn of bar type selecting device that is used to detect sliver and yarn.

Background technology

In the dried instrument checkout equipment of existing YG135G type bar, the yarn type selecting is provided with 5 yarn paths (a-e), tests the sliver and the yarn of different thicknesses respectively.As shown in Figure 3,1 is guide plate, 2 is slide plate, 10 is slide block, 11 is microswitch, slide block 10 is contained on the slide plate 2, can horizontally slip along its centerline direction, microswitch 11 vertically is contained in slide block 10 belows, the position at guide plate 1 middle part, slide block 10 slides left, can push down the transmission position of microswitch 11 in the time of directly over the f position arrival microswitch 11, turn left to slide from this position beginning slide block 10 and all can push down the transmission position of microswitch 11 always, the dried instrument of corresponding bar yarn path a-b can test, just can not pushed down from the turn right transmission position of slip microswitch 11 of this position beginning slide block 10, the dried instrument of corresponding bar yarn path c-e can test.Microswitch 11 has 3 contacts, and wherein contact 12 is a common point, constitutes one group of normally opened contact with contact 13, when did not press at microswitch transmission position, contact not conducting of 12-13 was when press at microswitch transmission position, contact 12-13 conducting, the dried instrument of bar this moment yarn path a-b can test.Common 12 constitutes one group of normally-closed contact with contact 14, when does not press at microswitch transmission position, and contact 12-14 conducting, the dried instrument of bar this moment yarn path c-e can test, when press at microswitch transmission position, contact not conducting of 12-14.Use this testing of equipment sliver and yarn to need frequent sliding slider 10, the microswitch loss is very fast, weares and teares easily in the contact, and bad adjusting of spacing during replacing between slide block 10 and the microswitch 11 and operation are very inconvenient, make a big impact to production.

Summary of the invention

For solving microswitch fault rate height, the not easily changeable deficiency of the existing dried instrument of bar, goal of the invention of the present utility model is to provide a kind of dried instrument yarn type selecting device, divide the yarn path with rotary switch control, to realize reducing the fault rate of the dried instrument of bar, the purpose that easy access is changed.

For achieving the above object, the utility model comprises testing circuit one and testing circuit two, and slide plate is contained on the guide plate, can be along the slide of guide plate, and rotary switch is contained on the shell; The common of the rotary switch of control yarn path a-b constitutes one group of contact with contact one and connects with testing circuit one, the common of the rotary switch of control yarn path c-e constitutes another group contact with contact two connects with testing circuit two, and the left rotation and right rotation of rotary switch 3 can realize dividing yarn path a-b or the testable purpose of c-e.

The utility model cancellation slide block and microswitch, use a rotary switch 3, rotary switch 3 is screwed into the left side, the testing circuit conducting of corresponding yarn path a-b, yarn path a-b can do test, and rotary switch is screwed into the right, the testing circuit conducting of corresponding yarn path c-e, yarn path c-e can do test, can conveniently divide the yarn path.

The utility model compared with prior art, cancelled slide block and microswitch in the former mechanism, slide plate has installed a rotary switch additional only as mechanical positioner, this rotary switch is contained in the dried instrument of bar side, the dismounting aspect is active in one's movements, reliably, and is easy to operate, long service life, simultaneously, switch is changed easy, need not adjust.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation sketch of the present utility model;

Fig. 2 is an electrical principle sketch of the present utility model;
