Description

TECHNICAL FIELD

[0001] The utility model relates to spinning machine field especially, it is a kind of spinning machine with compensating device. BACKGROUND

[0002] In the operation process of spinning machine, yarn is usually spun from yarn outlet device, then is guided and wound on material roll by yarn outlet nozzle. In order to realize the uniform winding of yarn on material roll, yarn outlet nozzle moves along certain direction in the process of yarn output, usually parallel to the direction of material roll axis, to ensure that yarn can be evenly distributed on material roll. However, this movement mode brings an additional horizontal motion component to yarn.

[0003] In the traditional spinning machine design, the speed of yarn spun by yarn outlet device is constant, and matches the material receiving speed of material roll. When yarn outlet nozzle carries yarn and moves along horizontal direction, this additional motion component can cause the speed of yarn at a moment to exceed the speed of yarn spun by yarn outlet device, or exceed the material receiving speed of material roll, thereby causing yarn tension to be too large, and even breakage.

DETAILED DESCRIPTION

[0020] The content of the application will be further described below in combination with specific embodiments:

[0021] A spinning machine with a compensation device, such as Figure 1As shown, the base is provided with a yarn outlet device 11 at the bottom end and a bobbin 12 at the top end, and a yarn outlet nozzle 13 is arranged between the yarn outlet device 11 and the bobbin 12, and the yarn spun by the yarn outlet device 11 is wound onto the bobbin 12 through the yarn outlet nozzle 13.

[0022] In order to enable the yarn to be wound evenly on the bobbin 12, the yarn outlet nozzle 13 carries the yarn to move in a direction perpendicular to the line connecting the yarn outlet device 11 and the bobbin 12 during the yarn output, i.e. parallel to the axis direction of the bobbin 12 in the embodiment.

[0023] When the yarn outlet nozzle 13 carries the yarn to move, a horizontal movement component will be given to the yarn, and the distance between the yarn outlet nozzle 13 and the line connecting the yarn outlet device 11 and the bobbin 12 is directly proportional to the horizontal movement component. However, the speed of the yarn spun by the yarn outlet device 11 is constant and equal to the winding speed of the bobbin 12, so the horizontal movement component will cause the yarn to break.

[0024] Therefore, a compensation device is arranged between the yarn outlet device 11 and the yarn outlet nozzle 13 in the application, which combines Figure 1 and Figure 2 As shown, the compensation device includes a compensation base 2, and a compensation wheel 3 is arranged on the compensation base 2, and the compensation wheel 3 is elastically connected to the compensation base 2 through an elastic device 4. The part where the compensation wheel 3 abuts against the yarn and the yarn abuts against the compensation device is configured as a compensation section, and the compensation section tends to be bent under the action of the elastic device 4. When the horizontal movement component of the yarn increases, the yarn overcomes the elastic force of the compensation device, so that the compensation section tends to be flat, thereby compensating for the movement component; and when the movement component decreases, the compensation device bends the compensation section, so that the part of the yarn other than the compensation section is straightened, and the next side compensation is prepared.

[0025] Specifically, the elastic device 4 includes a connecting rod 41, as shown in Figure 3 As shown, the connecting rod 41 includes a first rod body 411 fixed coaxially with the compensation wheel 3, a second rod body 412 fixed perpendicularly at the end of the first rod body 411 away from the compensation wheel 3, a rotating shaft 413 fixed at the end of the second rod body 412 away from the first rod body 411 and penetrating the compensation base 2, a third rod body 414 fixed perpendicularly at the end of the rotating shaft 413 away from the second rod body 412, and the third rod body 414 is connected to the compensation base 2 through an elastic member 42. The elastic member 42 drives the third rod body 414 to swing around the axis of the rotating shaft 413, so that the compensation wheel 3 connected to the first rod body 411 swings around the axis of the rotating shaft 413, thereby changing the elastic force of the compensation wheel 3 on the yarn. In the embodiment, the elastic member 42 is a spring or an elastic band.

[0026] The compensation device is further provided with auxiliary wheels 5, the axes of the auxiliary wheels 5 are parallel to the compensation wheel 3, and the auxiliary wheels 5 are arranged above and below the compensation wheel 3 respectively, the auxiliary wheels 5 keep fixed relative spatial positions with the compensation base 2, and can only rotate around the axes thereof, and the yarn is interlaced between the pair of auxiliary wheels 5 and the compensation wheel 3. Figure 4 As shown in the figure, the compensation wheel 3 and the auxiliary wheels 5 are both provided with ring grooves 6 around the axes thereof, and the yarn is matched with the ring grooves 6. The ring grooves 6 limit the displacement of the yarn perpendicular to the length direction of the yarn, so that the yarn is not easy to fall off from the compensation wheel 3 and the auxiliary wheels 5.

[0027] In other embodiments of the present application, the elastic device 4 can also be provided in a simple form, including elastic members 42 arranged at both ends of the compensation wheel 3 respectively, one end of the elastic member 42 is connected with the compensation wheel 3, and the other end is fixed on the compensation base 2. The compensation wheel 3 is controlled by the direct tension of the elastic member 42 to realize the control of the yarn compensation section.

[0028] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application, therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
