Technical Field

[0001] The utility model relates to the technical field of continuous textile machinery, in particular to a device suitable for removing a rubber roller bearing of a continuous spinning winding head. Background Art

[0002] The winding head rubber roller is an important transmission structure in the continuous spinning winding traverse system. After the power of the traverse box passes through the transmission shaft, the power is transmitted to the rubber roller by the synchronous belt inside the winding head, and then the friction force is used to drive the bobbin to rotate. The linear speed of the rubber roller is the same as the linear speed of the large and small processing rollers on the machine. The rubber roller is an indispensable and important accessory to ensure that the silk strips can be wound on the paper tube normally. Since the continuous spinning machine, the winding rubber rollers of small looms have often malfunctioned. On the one hand, the winding rubber rollers often malfunction, which seriously affects the production quality and easily causes poor bobbin forming, broken ends, mechanical hair, etc.; on the other hand, after the winding rubber roller fails, it can only be replaced with a new one, which increases production costs. Figure 6 The figure shows a schematic diagram of a continuous spinning winding head rubber roller bearing, wherein a circular groove is provided at the end of the winding head rubber roller, a winding head rubber roller shaft is provided at the center of the circular groove, the bearing sleeve is arranged on the winding head rubber roller shaft, and there is a narrow gap between the bearing and the bottom of the circular groove; the prior art has the following problems:

[0003] 1. The rubber roller bearing is difficult to remove after being worn;

[0004] 2. The gap between the bearing and the bottom of the circular groove is narrow, and the claws of the traditional bearing removal device are difficult to fix in the narrow space;

[0005] 3. Forcibly removing the rubber roller bearing will damage the rubber roller and directly lead to its scrapping;

[0006] 4. In some models, the scrap rate of rubber rollers is high, so that the production cost remains high.

[0007] The invention patent application with publication number CN110091287A discloses a bearing disassembly device, comprising: a plurality of disassembly hooks for hooking the bearing, a hook mounting seat, a limit ring for limiting the position of the disassembly hook relative to the hook mounting seat, a top plate and a plurality of connecting pieces; the disassembly hook is mounted to the hook mounting seat; the hook mounting seat is provided with a center hole for the shaft to pass through; the disassembly hook is arranged between the hook mounting seat and the limit ring; the limit ring is sleeved on the outer periphery of the hook mounting seat; the limit ring is provided with a through hole for the shaft to pass through; the connecting piece connects the top plate and the mounting seat; the bearing disassembly device also includes: a jack for applying a force to the top plate to drive the disassembly hook to move. The invention is beneficial in that the bearing disassembly device can be disassembled and installed, is small in size, light in weight and easy to carry; the bearing can be disassembled in a small space without opening the gearbox housing.

[0008] However, the bearing disassembly device of the patent is too large to be inserted into the circular groove at the end of the winding head rubber roller to work, and the disassembly hook of the patent is too large to be inserted into the narrow gap between the bearing and the bottom of the circular groove to fix the bearing.
