Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a pressed roller device. Background Art
[0002] The pressed roller device is generally a component structure of the doubling machine and belongs to textile machinery. The pressed roller is an important component structure of the precision doubling equipment. It is used to detect the yarn speed and plays an extremely important role in yarn forming.
[0003] The existing pressed roller adopts an integrated structure and requires external bearings at both ends to rotate. It has high requirements for installation. Improper installation can easily lead to necrosis of the bearings at both ends. It can also easily cause the creel to jump, and then cause damage to the top plate shaft. Because it is an external bearing, it is easy to get tangled in yarn and accumulate hairiness during long-term operation, which can cause the bearing to get stuck and then damaged. Summary of the invention
[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a pressed roller device.
[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: a pressed roller device, comprising a core shaft, an O-ring is provided at both ends of the core shaft, a roller is sleeved on the core shaft, a bearing is supported and connected between both ends of the roller and the core shaft, the bearing is arranged at a position corresponding to the O-ring, the bearing is arranged inside the roller, a fixed sleeve is provided in the roller outside the bearing, the fixed sleeve is fixedly connected to the roller, the inner ring of the fixed sleeve is slidably connected to the inner wall of the core shaft, and a magnet is embedded in the outer ring surface of the right end of the roller.
[0006] Preferably, a pressure roller mounting seat is provided at both ends of the mandrel, and the two ends of the mandrel are fixedly connected to the corresponding pressure roller mounting seats.
[0007] Preferably, a proximity switch mounting seat is provided on the pressure roller mounting seat on the right side.
[0008] Preferably, a proximity switch is provided on the proximity switch mounting seat, and the position of the proximity switch corresponds to the magnet.
[0009] The utility model has the beneficial effects of: by arranging the bearing inside the drum, setting the drum and the core shaft as two parts, and setting an O-ring between the connection position of the bearing and the core shaft, and setting a fixing sleeve inside the drum outside the bearing, the O-ring can reduce the vibration during rotation and the wear of the core shaft, and the fixing sleeve can prevent the yarn and feather from being entangled in the bearing and causing the bearing to be damaged, thereby increasing the service life of the bearing and avoiding damage to the pressure roller that affects yarn making; the embedded magnet can effectively prevent the magnet from flying off during high-speed operation, resulting in the inability to monitor the speed and affecting yarn making.
