STRING DRAWING APPARATUS OF STRINGING MACHINE

摘要

A string drawing apparatus of a stringing machine, comprising: a string clamping device (1), a sensor (2), a driving element (3), a transmission mechanism, and a control circuit (4). The sensor (2) is connected to the string clamping device (1), and is configured to detect tension applied to the string clamping device (1) and transmit a detected tension value to the control circuit (4); the control circuit (4) compares the detected tension value with a set value, and controls rotation of the driving element (3) according to the comparison resu the transmission mechanism comprises: a mounting base (5), a transmission sliding block (6), a transmission rack (7), and a driving gear (8); the driving gear (8) is connected to an output end of the driving element (3), and the transmission rack (7) is meshed with the driving gear (8) and is connected to the transmission sliding block (6); a guide column (9) is provided on the mounting base (5); the transmission sliding block (6) is sleeved on the guide column (9) and is connected to the sensor (2); the transmission sliding block (6) drives the sensor (2) and the string clamping device (1) to move forwards or backwards under driving of the driving gear (8), so as to enable a racket string to be tightened or loosened.
