Linkage device for realizing synchronous and same-phase running of all flyers or bobbins of roving frame

Abstract

The invention relates to a linkage device for realizing the synchronous and same-phase running of all flyers or bobbins of a roving frame, which comprises more than two driving units and an electric mechanism, wherein any one driving unit consists of 2 to 48 first synchronous pulleys, a second synchronous pulley, a synchronous belt and a motor, and any one first synchronous pulley is arranged on a keel; any one first synchronous pulley is connected by the synchronous belt, and any one motor is connected with a second synchronous pulley; tension pulleys can be arranged in the driving units, and any one first synchronous pulley is respectively connected with a flyer or a bobbin; the motor drives the synchronous pulley through the second synchronous pulley, and all second synchronous pulleys synchronously run in phase; and the synchronous belts drive the first synchronous pulleys in all driving units to synchronously run in phase, thereby realizing the synchronous and same-phase running, stop and state keeping of all the flyers or bobbins of the whole roving frame in any states including the state of complete loss of power.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to textile machinery, in particular to a roving frame, and in particular to a linkage device for synchronously operating all the flyers or bobbins of the roving frame in the same phase. Background technique: [0002] In order to improve the working speed of the roving frame, the roving frame uses a large number of flyers or bobbins for yarn winding. In the prior art, it is impossible to guarantee the driving mechanism of the flyer or the bobbin driven by multiple motors or a single motor, or it takes a high-cost electrical control system to realize the synchronous operation of all the flyers or bobbins, especially in the drive mechanism. When the power is completely lost, or when the operator maintains and cleans, or the bobbin and flyer are under the action of external force, the flyer or bobbin cannot be synchronized or stop at a fixed position in the same phase. All of the above situat...
