Description
Technical field
The present invention relates to a kind of tension control mechanism, be specifically related to a kind of be used to the counterweight tension roller mechanism of putting yarn.
Background technology
Along with expanding economy, people are increasing to the demand of textile product.The improvement that is used for the equipment of weaving has great facilitation to the efficient that improves weaving production.In weaving is produced, put the yarn production link that is absolutely necessary from spool, putting in the yarn equipment in the past, often adopt the pattern of freely putting yarn, the variation of namely not removing to consider to put yarn tension in the yarn process.Directly the yarn roller that can rotate on the spool socket board is carried out realizing putting yarn by the constant force traction.
But in recent years, along with the appearance of the equipment of weaving cotton cloth of precision control, often wish that yarn keeps constant tension force in putting the process of yarn.Often adopt servomotor to add corresponding feedback device formation now and initiatively put yarn.Equipment, but this has increased the cost of scrap build greatly.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of variation by weight to carry out the counterweight tension roller mechanism of tension force control.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
The counterweight tension roller mechanism, comprise: be provided with putting hole board, be arranged on bearing, jockey pulley in the above-mentioned board putting hole, the roll sleeve of mentioned strain roller is connected in the above-mentioned bearing, it constitutes vertical being rotationally connected of pivot center by bearing and board, above-mentioned outside race is captiveed joint with board, it is characterized in that, also comprise: be fixedly connected on above-mentioned roll shaft below the friction adjust bar, be socketed in the surge tank in the outside, above-mentioned friction adjust bar bottom; Above-mentioned roll shaft and bearing inner ring constitute the sliding block joint of vertical direction, above-mentioned surge tank top is formed with the first step of annular, above-mentioned friction adjust bar tip radius is less than the radius of above-mentioned roll shaft, be formed with the second step of annular between them, there is coil spring in the friction adjust bar outside between above-mentioned first step and the second step, above-mentioned friction adjust bar is divided into the section of loosening that is positioned at the top and is positioned at the friction section of below, the radius of the above-mentioned section of loosening is less than the radius of friction section, above-mentioned surge tank be positioned at above-mentioned first step below be provided with multilayer friction band, above-mentioned every layer of friction band is for being evenly distributed on a plurality of free rolling steel balls on the circumferencial direction.
Aforesaid counterweight tension roller mechanism is characterized in that, above-mentioned surge tank is provided with a plurality of be used to the placement slotted eye that holds above-mentioned steel ball, and above-mentioned placement slotted eye is stepped hole.
Aforesaid counterweight tension roller mechanism is characterized in that, the number of above-mentioned every layer of steel ball is 6.
Usefulness of the present invention is: the variation by gravity changes the number of the friction band that contact with the friction adjust bar, and by the moment of torsion of friction force adjusting roll shaft, thereby the realization tension adjustment is simple and practical, is convenient to the transformation of existing installation.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the present invention.
The implication of Reference numeral among the figure:
1-board, 2-bearing, 3-jockey pulley, 301-roll shaft, the 4-adjust bar that rubs, 5-surge tank, 6-coil spring, 7-steel ball.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to shown in Figure 1, counterweight tension roller mechanism of the present invention comprises: be provided with putting hole board 1, be arranged on bearing 2, jockey pulley 3 in the board putting hole, be fixedly connected on roll shaft 301 belows friction adjust bar 4, be socketed in the surge tank 5 in the outside, friction adjust bar 4 bottoms.
The roll shaft 301 of jockey pulley 3 is socketed in the bearing 2, and it constitutes vertical being rotationally connected of pivot center by bearing 2 and board 1, captives joint with board 1 in bearing 2 outer rings.Roll shaft 301 and bearing 2 inner rings constitute the sliding block joint of vertical direction, surge tank 5 tops are formed with the first step of annular, friction adjust bar 4 tip radius are less than the radius of roll shaft 301, be formed with the second step of annular between them, there is coil spring 6 in friction adjust bar 4 outsides between first step and the second step, friction adjust bar 4 is divided into the section of loosening that is positioned at the top and is positioned at the friction section of below, the radius of the section of loosening is less than the radius of friction section, surge tank 5 be positioned at first step below be provided with multilayer friction band, every layer of friction band is for being evenly distributed on a plurality of free rolling steel balls 7 on the circumferencial direction.
So, spool yarn on the yarn roller is many, when the radius of yarn is big, because the effect of coil spring 6, friction adjust bar 4 does not contact with the steel ball 7 of any one friction band, when yarn weight reduces on the yarn spool owing to putting, yarn place radius reduces, so tension force reduces, and this moment, coil spring 6 upwards ejected the yarn roller, and the adjust bar 4 that rubs this moment does not contact with the steel ball 7 of one or several friction band, this will see the degree of loss of weight, the loss of weight bright yarn place radius of more speaking more is more little, needs the more multi-layered friction of contact bring the torque that influence roll shaft 301, realizes that tension force controls.
As preferred version, surge tank 5 is provided with a plurality of be used to the placement slotted eye that holds steel ball 7, the placement slotted eye is stepped hole, after treating that steel ball 7 is put into, can put into steel ball 7 one sides with placing slotted eye by other part shutoff, this part can limit the position of steel ball, and its friction section with friction adjust bar 4 is contacted.Further as preferred version, the number of every layer of steel ball 7 is 6.
More than show and described groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
