Description

Technical Field

[0001] The utility model relates to the technical field of doubling machines, in particular to a friction shaft support for doubling machines. Background Art

[0002] The friction shaft of the winding machine is a supporting component for overlapping the yarn tube, which is used to provide support for the yarn tube when it rolls. It is installed on the winding machine through supports arranged on both sides. Bearings are installed inside the supports and are connected to the shaft rod of the friction shaft, so that the friction shaft can be driven to rotate synchronously during the rotation of the yarn tube, reducing the friction between the two. Since the winding machine will generate high-frequency vibrations when working, the vibration will cause friction between the bearings in the friction shaft support and the mounting holes, which will cause wear on the hole wall and expansion of the hole body, which will reduce the stability of the friction shaft during rotation, resulting in up and down vibrations during rotation, which will cause the yarn tube to rotate unsteadily. To avoid this phenomenon, the friction shaft support needs to be replaced after a period of use. Frequent replacement leads to increased costs, which is not conducive to the production operation of the factory.

[0003] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0004] The utility model aims to solve the above-mentioned deficiencies and provide a friction shaft support for a doubling machine.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The friction shaft support of the doubling machine includes a mounting plate installed and connected to the doubling machine and a fixing sleeve arranged on the mounting plate for installing the bearing, a mounting hole for installing the bearing is arranged in the middle of the fixing sleeve, a clamping groove is arranged at the bottom end part of the fixing sleeve on the side away from the mounting plate, and the clamping groove is matched with a supporting block that can be movably embedded for supporting the outer surface of the bearing; the side of the supporting block close to the center part of the fixing sleeve is a component of the mounting hole; a movable groove gap for the supporting block to slide is arranged between the bottom end of the supporting block and the clamping groove; a first bolt that is movably engaged with the outer surface of the supporting block is threadedly connected to the side wall of the clamping groove.

[0007] Furthermore, it also includes a stabilizing component for automatically engaging the support block against the surface of the outer ring of the bearing.

[0008] Furthermore, the stabilizing component includes a receiving hole opened on the back of the supporting block and a resisting spring arranged in the receiving hole; when the resisting spring is in a natural state, one end thereof extends out from the receiving hole.

[0009] Furthermore, a thrust plate having a diameter no greater than the inner diameter of the accommodating hole is provided at one end of the thrust spring away from the accommodating hole.

[0010] Furthermore, a second bolt is threadedly connected to the side wall of the embedding groove; when the support block is completely embedded in the embedding groove, the second bolt is opposite to the thrust plate.

[0019] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 The friction shaft support of the doubling machine shown in the figure comprises a mounting plate 1 installed and connected between the doubling machine and a fixing sleeve 11 arranged on the mounting plate 1 for mounting a bearing. A mounting hole 12 for mounting a bearing is arranged in the middle of the fixing sleeve 11. A clamping groove 2 is arranged at the bottom end of the fixing sleeve 11 away from the mounting plate 1. The clamping groove 2 is equipped with a supporting block 21 that can be movably embedded and used to support the outer surface of the bearing. The side of the supporting block 21 close to the center of the fixing sleeve 11 is a component of the mounting hole 12. A fixing hole 12 is arranged between the bottom end of the supporting block 21 and the clamping groove 2. There is a movable groove 22 for the supporting block 21 to slide; a first bolt 23 is threadedly connected on the side wall of the embedded groove 2 and movably engages with the outer surface of the supporting block 21. The supporting block 21 is arranged in the embedded groove 2 in a form that can move back and forth. When the bearing is installed in the mounting hole 12 and used for a period of time, the hole wall of the mounting hole 12 is worn and expanded. By rotating the first bolt 23, the supporting block 21 is moved toward the bearing side, and then the bearing is tightened to prevent it from loosening, thereby eliminating the need to replace the support, thereby increasing the service life of the support.

[0021] In one embodiment, a stabilizing component is also included for automatically abutting the support block 21 against the surface of the outer ring of the bearing. Since it is inconvenient to intervene in the adjustment process of the support block 21 by the first bolt 23 when the winding machine is running, and the winding machine runs continuously for a long time, when the bearing becomes loose during operation, it is necessary to stop the machine to adjust the support block 21, which causes delays in production. Therefore, a stabilizing component is provided to enable it to continuously provide abutting force on the support block 21 when the winding machine is running, so that it can temporarily stabilize the abutment against the bearing, and there is no need to stop the machine for adjustment.

[0022] The specific structure of the stabilizing component is that a receiving hole 3 is opened on the back of the support block 21, and a push spring 31 is arranged in the receiving hole 3; when the push spring 31 is in a natural state, one end thereof extends out from the receiving hole 3, and then after the support block 21 is installed on the embedding groove 2, the push spring 31 will abut against the inner wall of the embedding groove 2, thereby compressing itself. When the hole wall of the mounting hole 12 wears and causes the gap between the support block 21 and the bearing to increase, the push spring 31 will push the support block 21 toward the bearing side to continuously provide a supporting force for the support block 21.

[0023] In one embodiment, a thrust plate 4 having a diameter no greater than the inner diameter of the accommodating hole 3 is provided at one end of the thrust spring 31 away from the accommodating hole 3. By providing the thrust plate 4, the contact surface between the thrust spring 31 and the inner wall of the embedding groove 2 is increased, providing a stable supporting point.

[0024] In one embodiment, a second bolt 5 is threadedly connected to the side wall of the embedding groove 2; when the support block 21 is fully embedded in the embedding groove 2, the second bolt 5 is directly opposite to the thrust plate 4. Through the setting of the second bolt 5, the support force of the push spring 31 on the support block 21 can also be adjusted. When it rotates to engage the thrust plate 4, it can also push the push spring 31 to compress, thereby increasing the thrust of the push spring 31 on the support block 21, thereby maintaining the support stability.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
