The former is of coarse appearance, great weight, high possibility of surface stuck with flying and difficulty in cleaning; the later is of high cost, great power consumption, complicated structure and difficult installation. The utility model comprises a spindle tape tension pulley, a corbel piece for installing the tension pulley and a tension axis for fixing the tension device, wherein, the corbel piece is arranged on a pin roll, a double-torsional spring is sleeved on the pin roll, the double-torsional spring and the pin roll are fixed together, the two ends of the double-torsional spring are positioned with locating blocks on the inner wall of a left box and a right box, after the left and the right boxes are closed, the pin roll and the double-torsional spring are sealed in the box, the position on the left and the right boxes corresponding to the corbel piece is provided with a notch for the corbel piece to sway, and the left and the right boxes are fixed with the tension axis through an end closure by bolts. The utility model has the advantages of simple structure, convenient installation, reliable control and low cost.

Description

The spindle band tensioning apparatus of ring throstle

Technical field

The utility model relates to ring throstle, especially the tensioning apparatus of ring throstle.

Background technology

The tensioning apparatus of ring throstle transmission spindle band mainly contains two kinds of forms at present, and a kind of is single tension pulley Weight type, and another kind is two tension pulley extension spring types.Single tension pulley Weight type spindle band tensioning apparatus is the version that present fine spining machine manufacturer generally adopts.Its advantage is: simple in structure, number of spare parts is few, reliable in action; Most parts adopt foundry goods, and presentation quality is less demanding.Operation principle: it is the deadweight that utilizes weight (the about 1.7kg of quality), by the lever of being made up of case, support arm, tension axis, makes the spindle band tension pulley that is installed on the support arm produce rightabout pulling force, thereby makes position spindle band tensioning thereon.The shortcoming of this tensioning form is: outward appearance is coarse, weight big (the about 3.0kg of single cover), and the easily sticking flyings in surface, not easy to clean.In addition, by 15000 calculating of the present fine spining machine annual production of China, need about 5175 tons of year consumption foundry goods.And produce the severe contamination that these foundry goods can cause environment, therefore, in today that environmental protection is more and more paid attention to, the production of this low value-added product more and more is restricted.Since individual power take inventory shortcoming, both at home and abroad fine spining machine manufacturer has developed the different two tension pulley device tensioning of form successively.Its advantage is: the sth. made by twisting of spun yarn is convenient to conversion, and spindle band tension force is subjected to the spindle band effect length little, uniform tension in order.Operation principle: two tension pulleies are separately fixed on two support arms, the support arm lever connector by separately respectively is fixed on the fulcrum, the other end at two levers is equipped with extension spring, effect by extension spring and lever makes respectively that two tension pulleies produce left, pulling force to the right, thereby makes the spindle band tensioning that is positioned on the tension pulley.Its shortcoming is: the cost height, and power consumption is big, must have two tension pulleies to work simultaneously, and complex structure needs to change traditional installation form at present, transforms, installs difficulty.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of simple in structure, easy for installation, and control is reliable, the spindle band tensioning apparatus of lower-cost ring throstle.

Taked following technical measures for realizing goal of the invention the utility model: a kind of spindle band tensioning apparatus of ring throstle comprises: the support arm of spindle band tension pulley and installation tension pulley, and the tension axis of fixed tensioning device.Described support arm is installed on the bearing pin, bearing pin outside suit torsion spring, torsion spring and bearing pin are fixed, locate with the locating piece of left box, right box inwall respectively at the two ends of torsion spring, after left and right box fastens, bearing pin and torsion spring are enclosed in the box, are having for the notch that props up arm swing with the pairing position of support arm on the left and right box, and left and right box is fixed with bolt and tension axis by end cap.

Described support arm is installed on the bearing pin, is in the center of bearing pin processing screw hole, and fastening with screw and support arm.Described torsion spring and bearing pin are fixed, and are at the middle part of bearing pin cross machine screw, and with Screw the middle part of torsion spring are fixed.

The utility model compared with prior art has the following advantages:

1, simple in structure, external form is smooth, and is easy to clean behind the sticking flyings; 2, influenced by spindle band length little for spindle band tension force size, uniform tension in order; 3, cost is low; 4, do not change tension pulley traditional installation form at present, new second-hand machine all can use, and is easy for installation.

The specific embodiment

Shown in Fig. 1～9, a kind of spindle band tensioning apparatus of ring throstle comprises: the support arm 2 of spindle band tension pulley 1 and installation tension pulley, and the tension axis 7 of fixed tensioning device.Described support arm 2 is installed on the bearing pin 3, bearing pin 3 outside suit torsion springs 4, torsion spring 4 is fixing with bearing pin 3, locate with the locating piece 11 of left box 5-1, right box 5-2 inwall respectively at the two ends of torsion spring 4, after left and right box fastens, bearing pin 3 is enclosed in the box with torsion spring 4, is having for the notch 9 that props up arm swing with support arm 2 pairing positions on the left and right box, and left and right box is fixing by end cap 8 usefulness bolts and tension axis 7.

Described support arm 2 is installed on the bearing pin 3, is in the center of bearing pin 3 processing screw hole, and fastening with screw 10 and support arm.Described torsion spring 4 is fixing with bearing pin 3, is at the middle part of bearing pin 3 cross machine screw, and with Screw 6 middle part of torsion spring 4 is fixed.

The course of work of the present utility model: this device is fixed on the tension axis 7 by screw, effect by torsion spring 4 makes support arm 2 generations torsion left, thereby make the tension pulley 1 generation pulling force left that is installed on the support arm 2, finally make the spindle band 12 that is positioned on the tension pulley 1 be able to tensioning.

Obviously; those skilled in the art can change and is out of shape the utility model; if these changes and distortion do not break away from principle of the present utility model; the scope that belongs to claim of the present utility model and equivalent technologies thereof, protection domain then of the present utility model also comprise these changes and are out of shape interior.
