Constant-tension taping machine

Abstract

The invention provides a constant-tension taping machine which comprises a base plate, a tape releasing device, a taping device and a controller. A main shaft is rotationally arranged at an upper endof a fixed seat and is in transmission connection with a first driving mechanism, the tape releasing device is fixedly arranged at a right end of the main shaft, an inner shaft is rotationally arranged in the main shaft and is provided with a wire passing hole, and one end and/or two ends of the inner shaft are fixedly connected with the base plate; the tape releasing device comprises a tension adjusting mechanism, a left baffle, a tape storage barrel and a right baffle. The left baffle, the tape storage barrel and the right baffle are sequentially connected to the right end of the main shaftin a sliding and sleeving mode, the right baffle is in transmission connection with the main shaft through a key body, and the tension adjusting mechanism can control tension on a discharged tape material by adjusting pressure exerted on two end faces of the tape storage barrel by the left baffle and the right baffle. The taping device is fixedly arranged at a right end part of the main shaft. According to the taping machine, the same transmission system is adopted for the tape releasing device and the taping device, and the controller applies friction torque to the tape storage barrel in realtime through the tension adjusting mechanism so as to achieve the constant control over the tension value of released tape material.

Description

technical field [0001] The invention relates to the technical field of cable production equipment, in particular to a constant tension tape wrapping machine. Background technique [0002] The taping machine is mainly composed of a taping device and a tape unwinding device, wherein the tape wrapping device is responsible for winding the tape material onto the core wire, and the tape unwinding device is responsible for outputting the tape material. The tape is generally stored in the tape storage drum, and the tape storage drum can be rotated to output the tape, and the output speed of the tape must match the winding speed of the taping device to ensure the normal operation of the tape. [0003] The constant tension of the tape material released by the tape unwinding device is a key factor affecting the quality of the cable tape. In the prior art, in order to realize the constant tension of the tape material, a solution is: in addition to setting the main transmission system ...

Problems solved by technology

In the prior art, in order to realize the constant tension of the tape material, a solution is: in addition to setting the main transmission system of the tape wrapping device on the taping machine, a separate transmission system is also provided for the tape unwinding device, in order to provide power for the tape unwinding device , so that the tension value of the tape material released by the tape unwinding device is constant, but the overall structure of the taping machine is complex, and it is difficult to manufacture, process and maintain; another solution is: the taping machine uses a hysteresis tensioner or magnetic powder tension The device is used as the tension source when the tape is unloaded, so as to ensure that the tension value of the tape released by the unwinding device is always kept in a constant range when the tape diameter on the tape reel changes. However, due to the hysteresis tension device or magnetic powder After the tensioner works for a long time, the magnetic powder will age, and the high temperature of the magnetic powder will cause some scarring or adhesion of the magnetic powder particles due to moisture, resulting in loss of function. The magnetic powder needs to be replaced frequently, which is inconvenient to maintain. Demagnetization is prone to occur, making the tension value of the tape material released by the tape unwinding device unstable, which in turn affects the tape quality of cable products
