Tape replacing device of belt type conveyer

The invention relates to a tape replacing device of a belt type conveyer, applied to an adhesive tape machine industry, comprising four parts, i.e. a tape winding device, a tape releasing device, a tape storing device and a traction device, wherein the tape winding device, the tape releasing device, the tape storing device and the traction device are sequentially arranged; a first bracket of the tape winding device adopts four trapezoidal structures; the output part of a driving device adopts a hollow shaft structure, and a transmission shaft adopts a solid shaft structure; one side end part of the transmission shaft is provided with a square groove; the hollow shaft of the driving device is connected and fixed with the transmission shaft through a locking disc; a first square shaft is a square solid shaft; a tape core is arranged between two guard rings; the first square shaft end is embedded into the square groove positioned on the transmission shaft end; a clamp ring is in an annular structure; the first square shaft is fixed with or separated from the square groove positioned on the transmission shaft end; a positioning pin is fixed with the clamp ring; and a double-bearing seat is in a mode of symmetrically arranging two independent bearing seats. The tape replacing device can be used for replacing a tape of the integral adhesive tape machine by fixing on one point; links are closely connected in the whole tape replacing process; and in addition, an optimal process is selected, and the installation position of the tape replacing device is freely selected, which is very beneficial the use for the adhesive tape machine; and the labor intensity of operators is greatly reduced through the innovation of the tape replacing device.
