Description

Warp tension measuring mechanism

Technical field

The utility model relates to the measuring mechanisms on weaving loom, and in particular to the tension born to warp thread set on loom The mechanism that size measures.

Background technique

The mechanism of the mechanism for measuring to warp tension set on loom is at present: the tension of warp thread It acts on the back rest, rotation band dynamic tension detection attachment base (also known as attachment base) rotation of arm is held by the back rest, thus by yarn The tension force effect of line realizes the purpose of detection warp tension size on (tension detection) sensor.Current tonometry machine In structure, two axis holes of attachment base are all fixed in the rack of loom, are incuded by the flexible micro-deformation of attachment base The size of tension, this micro-deformation are affected by factors such as the changes in material of part, the installation accuracies of part, simultaneously as The back rest actually weaving in be warp let-off linking arm drive reciprocating motion, certainly will cause sensor fluctuation it is larger, can how certain journey Cause warp tension testing value unstable on degree.

Utility model content

To obtain the measurement result more accurate to warp tension size, the utility model provides a kind of warp tension survey Measuring mechanism.

The technical solution adopted by the utility model to solve its technical problems is that:

A kind of warp tension measuring mechanism includes back rest adjustment support, the connection on back rest adjustment support is arranged in Seat, the back rest hold arm, and the sensor for detecting warp tension；The back rest holds lower end and the warp let-off linking arm phase of arm Matching, middle part is matched with the back rest；Warp tension can act on the back rest through the back rest and hold arm, then act on attachment base On, and it is sent to sensor, it is characterised in that: the attachment base and the back rest hold the upper end of arm by can be realized relatively The fit system of rotation matches；It can be realized the cooperation side of relative rotation between the attachment base and back rest adjustment support Formula matching.

In specific embodiment, the cooperation of the back rest and back rest gripping arm can guarantee the two shape at cooperation At relative rotation.

In specific embodiment, the back rest holds arm with the back rest and pivotally cooperates, and pivot cooperation position is equipped with Bearing.

In specific embodiment, the upper end that the attachment base holds arm with the back rest cooperates through pin shaft, and pin shaft is equipped with Sleeve or bearing.

In specific embodiment, is cooperated between the attachment base and back rest adjustment support by pin shaft, set on pin shaft There are sleeve or bearing.

Beneficial effect is: compared to existing tonometry mechanism, scheme involved in the utility model can be obtained pair The more accurate measurement result of warp tension size.

Specific embodiment

Structure depicted in Figure of description, ratio, size etc., only to cooperate the revealed content of specification, with Understand for those skilled in the art and read, is not intended to limit the utility model enforceable qualifications, therefore does not have skill Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the utility model institute Under the effect of capable of generating and the purpose that can reach, it should all still fall in what the revealed technology contents of the utility model can be covered In range.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to chat That states is illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, without substantive change Under more technology contents, when being also considered as the enforceable scope of the utility model.

Warp tension measuring mechanism as shown in Figure 1 and Figure 2, includes back rest adjustment support 1, and setting is adjusted in the back rest Attachment base 3, the back rest on support 1 hold arm 5, and the sensor 8 for detecting warp tension.The back rest holds arm 5 Lower end matches with warp let-off linking arm 7, and middle part is matched with the back rest 2.The tension of warp thread 9 can act on the back rest through the back rest 2 Arm 5 is held, is then acted on attachment base 3, and is sent to sensor 8.

As shown in Figures 1 to 4, the attachment base 3 holds the upper end of arm 5 with the back rest to be capable of the cooperation of relative rotation Mode matches.In diagram, the upper end that the attachment base 3 holds arm 5 with the back rest cooperates through pin shaft b6, and pin shaft b6 is placed in connection In seat 3, pin shaft b6 is equipped with bearing 10.The inner ring tight fit of pin shaft b6 and bearing 10, outer ring and the back rest of bearing 10 can be held 5 tight fit of gripping arm.In other embodiments, sleeve can be also set on pin shaft b6 instead of bearing 10.The attachment base 3 with it is described It can be realized the fit system matching of relative rotation between back rest adjustment support 1.In diagram, the attachment base 3 with it is described after Cooperated between beam adjustment support 1 by pin shaft a4, the one end pin shaft a4 is securely fitted on back rest adjustment support 1, and pin shaft a4 is another End is equipped with bearing 11.It can be by the inner ring tight fit of pin shaft a4 and bearing 11, the outer ring of bearing 11 and 3 tight fit of attachment base.? In other embodiments, sleeve can be also set on pin shaft a4 instead of bearing 11.

In specific embodiment, the back rest 2 holds the cooperation of arm 5 with the back rest, can guarantee the two at cooperation Form relative rotation.The back rest 2 holds arm 5 with the back rest and pivotally cooperates, and pivot cooperation position is equipped with bearing.

As shown in Figure 1 and Figure 2, after in the tension force effect of warp thread 9 to the back rest 2, the back rest can be driven to hold arm 5 around pin shaft b6 There is the rotation trend rotated clockwise, so that active force is transferred on attachment base 3, drives attachment base 3 to have around pin shaft a4 inverse The rotation trend of hour hands rotation, finally makes sensor 8 experience pressure, and senses the Tensity size of warp thread 9.Due to entire Mechanism only has attachment base 3 to adjust on support 1 by the rotatable back rest that is fixed on of pin shaft a4, leads to the gravity and warp of entire mechanism The tension of yarn 9 has all acted on sensor 8.On 8 Impact direction of sensor, as shown in Figure 1, on the excessively described attachment base 3 The influence for the mechanism gravity that the smaller sensor 8 of included angle A formed between the plane and vertical plane in the axle center of set two pivot pin 4,6 is subject to It is smaller.So preferably guaranteeing that included angle A should be less than normal as far as possible when cooperation position is arranged, to eliminate fuselage gravity as far as possible to measurement As a result influence guarantees the accuracy of measurement.

Above embodiment is only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new Type.The utility model can be improved there are many more aspect under the premise of without prejudice to overall thought, for being familiar with this technology Personage can all be carried out modifications and changes to above-described embodiment under the spirit and scope without prejudice to the utility model.Therefore, Such as those of ordinary skill in the art is in spirit revealed without departing from the utility model and institute under technical idea All equivalent modifications or change completed, should be covered by the claim of the utility model.
