TECHNICAL FIELD
[0001] The utility model relates to a yarn carrier drive mechanism of energy -conserving two -dimensional fabric equipment belongs to braiding equipment technical field. BACKGROUND
[0002] The existing braiding equipment carrier drive mechanism is the coupling of gear and pawl which rotates around the core pipe through the way of dropping oil, the pawl piece of yarn carrier is inlaid on the gear, the coupling of gear and pawl is set on the outer periphery of core pipe, one end of core pipe is installed with lower plate, the other end is installed with guide rail plate, and is fixed through bolt, gear rotation drives pawl to rotate, the coupling of gear and pawl rotates around core pipe and drives yarn carrier to move, the friction between the coupling of gear and pawl and core pipe is relatively large, and frequent oil dropping reduces production efficiency.
[0003] After improvement, the sliding friction mode is adopted between the gear inner hole and fixed shaft in the transmission box of traditional braiding machine. In order to reduce the friction, lubricating oil is usually added in the transmission box. However, during the long-term high-speed operation, the teeth surfaces of the dial gear are frequently rubbed, which causes the wear of the teeth surfaces. The impurities generated after the wear can mix into the lubricating oil, which reduces the performance of the lubricating oil, and the lubricating oil needs to be replaced regularly, which undoubtedly increases the production cost. In addition, the lubricating oil in the transmission box is also prone to oil leakage and splashing during the transmission process, thereby causing the pollution of the workshop environment.
[0004] On the other hand, the yarn carrier drive mechanism in the prior art has low assembly precision, and the height of the dial is difficult to accurately control. If the height of the dial is not uniform, abnormal vibration and noise are likely to occur during the operation of the equipment. If the spindles operate on the dial with uneven height, the spindles and the dial will further collide, the weaving line carried by the spindles will swing at different angles, and the density uniformity and appearance flatness of the fabric will be affected, thereby affecting the product quality. During the assembly process, the low-precision assembly method also increases the difficulty and time cost of assembly. UTILITY MODEL CONTENTS
