Description

Last hand stretching frame tension-adjusting gear

Technical field:

The utility model relates to a kind of parts of bobbin-winding machine, particularly a kind of assembly of going up the hand stretching frame.

Background technology:

Existing bobbin-winding machine, its yarn is all directly guided the yarn tube into from the frame that stretches tight, during work, yarn is tensioning state between frame and the yarn tube stretching tight, be yarn under the certain force of strain effect around to the yarn tube, when the reeled yarn on the frame that stretches tight made leading on the yarn drag tension force greater than Yarn strength owing to yarn sheet has some setbacks, yarn fractureed in this tension force effect, this phenomenon happens occasionally in existing bobbin-winding machine, and its consequence that may bring is:

1, because that above-mentioned broken string produces is inevitable, existing winder regulation is had the broken end index of a certain amount of permission, and broken end descends the quality of a yarn, and Yarn break out of control constantly occurs, might surpass the broken end desired value of regulation, bring extra economic loss to the dealer;

2, yarn is unlikely to fracture in order to make, especially lower to tension intensity yarn, the common probability that adopts lower winding speed to fracture with minimizing, but the obvious decline that brings production efficiency thus;

3, because creel to the yarn winding tension of yarn tube is difficult to control, the broken end phenomenon also can't be avoided, and the yarn that some qualities are higher is difficult to use bobbin-winding machine to carry out auto reeling, moves back and manually to finish relevant work, and is time-consuming;

4, in the operating winding process, fracture and may cause yarn winding at random on the creel owing to produce yarn, cause and be forced to out of servicely, have a strong impact on normally carrying out of production.In view of above-mentioned these phenomenons, prevent that the hand stretching frame from not fractureing to not producing yarn between the solderless wrapped connection of yarn tube is transmitted why, or reduce yarn as far as possible and fracture, overcome the serious quality shortcoming of existing reeled yarn winder broken end, be dealer's problem demanding prompt solution.

The utility model content:

Technical problem to be solved in the utility model is, the frame tension-adjusting gear that stretches tight on a kind of is provided, and its can keep the stretching tight yarn of solderless wrapped connection between frame and yarn tube does not fracture or reduces the probability that it fractures, and can adapt to the yarn of various varying strengths.

The technical scheme in the invention for solving the above technical problem is: a tension compensating bar is set on the axle of the frame that stretches tight and is bearing fit, supported end at the tension compensating bar is provided with an offset hole, hook is provided with a tension bar in the offset hole, the bottom of tension bar is connected with an elastic element, elastic element is connected with a U-shaped bar, one release handle is rotatably connected in sleeve pipe, the bottom face of release handle is resisted against the top of U-shaped bar, the bottom of tension bar is connected with a pipe link, the bottom of pipe link is colluded and is provided with a pull bar, drag link sleeve is provided with a rocking bar, and the rocking bar top is provided with the one stroke switch.The release handle turn is through the pretension value of U-shaped bar scalable elastic element, thereby yarn tension through tension bar control tension compensating bar rod end, yarn matter is crisp, revolve on the release handle, yarn matter is tough, the release handle backspin, when yarn tension during greater than the release handle preset value, the tension compensating bar is around the axle bottom, and pipe link will be carried on the rocking bar, the travel switch effect, the motor braking device does not change motor braking, keep yarn continuous, and dissimilar yarns, all can be adjusted to the predetermined tension value that adapts by release handle.

The structure of the utility model mat one scalable predetermined tension value makes the yarn perseverance be in safe work state, thereby has overcome the serious quality shortcoming of traditional bobbin-winding machine reeled yarn winder broken end, and can adapt to various yarns, enlarges Applicable scope, and enhances productivity simultaneously.The member that the utility model is set up is few, and is little to the equipment cost influence.
