Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the present invention provides a thrust bearing type herringbone arm of a spun yarn collecting system, comprising: the device comprises a long arm 1, a short arm 2 hinged on the long arm 1, a rotating support 3 hinged at one end of the long arm 1, a movable base 4 hinged at the other end of the long arm 1, and a fixed base 5 hinged on the short arm 2. One end of the short arm 2 is hinged to the long arm 1, and the other end of the short arm 2 is hinged to the fixed base station 5. And the two ends of the long arm 1 and the short arm 2 are respectively provided with a connecting structure 6. The connecting structure 6 comprises two connecting pieces 61 which are buckled with each other. One end of the connecting piece 61 is fixed on the long arm 1 or the short arm 2, and the other end of the connecting piece 61 is provided with a bearing groove 611. A thrust bearing 62 is placed in the bearing groove 611, and the thrust bearing 62 is disposed between the connecting member 61 and the long arm 1, the rotating bracket 3, the movable base 4, or the fixed base 5. During operation, activity base station 4 carries out the translation to drive long arm 1 and remove, at the hinge structure that articulated position formed, thereby make long arm 1 and short arm 2 rotate around articulated position and make the gas frame at both ends and transportation track be close to each other, with this realization collective doffing work. When the moving mechanism on the rotating bracket 3 drives the long arm to move relative to the air frame, axial thrust can be received at each hinged position, and the axial movement is limited by the thrust bearing 62, so that the long arm 1 and the short arm 2 are prevented from swinging in the axial direction, and the movement stability of the whole mechanism is ensured.

In some embodiments, the thrust bearing 62 is a thrust ball bearing. The thrust bearing 62 is generally classified into a thrust ball bearing and a thrust roller bearing. The rolling bodies of the thrust ball bearings are spherical, and the ferrules are provided with corresponding R-shaped channels. Such bearings can withstand axial loads but not radial loads. Because the rolling bodies are spherical and have small friction with the diameter of the roller path, the rolling device can be suitable for occasions with higher working rotating speed. The thrust roller bearing rolling element is in various forms such as a cylinder type, a cone type or a spherical roller type. The bearing mainly bears axial load, and the conical roller type and the spherical roller type can bear certain axial load. The thrust roller type bearing is suitable for bearing heavy axial load and occasions with low rotating speed because the contact area between the rolling body and the raceway is large, the friction force is correspondingly larger than that of a thrust ball bearing, and the limit rotating speed is lower than that of the thrust ball bearing. Because the herringbone arm only needs to guarantee to restrict the force in the axial direction, the requirement for avoiding the mechanism from shaking can be met by adopting the thrust ball bearing.

One end of the connecting piece 61 fixed on the long arm 1 or the short arm 2 is provided with a plurality of connecting holes 612, and the connecting piece 61 is fixedly connected with the long arm 1 or the short arm 2 by passing through the connecting holes 612 through screws. The connecting members 61 are fixed to both ends of the long arm 1 or the short arm 2 by screws passing through the connecting holes 612 of the connecting members 61 on both sides, so that the installation of the thrust bearing 62 and the hinge formation are facilitated, and the motion requirements of the herringbone arm are met.

The movable base platform is characterized in that the fixed base platform 5 is connected with a conveying track, the fixed base platform 5 is fixedly arranged on the conveying track, the movable base platform 4 is movably arranged on the conveying track, the movable base platform 4 is connected with a power mechanism, and the power mechanism drives the movable base platform 4 to reciprocate along the conveying track. The power mechanism adopts a cylinder, an electric push rod or a worm and worm wheel. The rotary yarn bobbin winder is characterized in that a rotary block is arranged on the rotary support 3 and connected with an air frame, one end of the rotary block is hinged to the rotary support 3, the other end of the rotary block is hinged to the air frame, and a plurality of yarn bobbins are arranged on the air frame. The movable base platform 4 is pushed to move through the power mechanism, so that the long arm 1 is driven to move, the herringbone arm is moved, the conveying track and the air frame are driven to be close to or far away from each other, and the requirement of collective doffing work is met.

To sum up, the utility model discloses a thrust bearing restricts the ascending motion of axial to avoid long arm and short arm to rock in the axial direction, guarantee the stationarity of whole mechanism's motion with this, be adapted to the repacking on the original mechanism basis.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
