A tape unwinding device

Abstract

The invention relates to the technical field of strip processing, and discloses a strip coil unwinding device. The device comprises a fixing support, a rotating shaft, a chassis, a sliding detection assembly and a controller, wherein the rotating shaft is rotationally connected with the fixing support; the chassis is arranged on the rotating shaft in a penetrating manner; a strip coil is arrangedon one side of the chassis, the rotating shaft drives the chassis and the strip coil to rotate synchronously so as to realize unwinding, a detection opening is formed in the chassis; the sliding detection assembly is arranged on the back surface of the chassis, the sliding detection assembly comprises a sliding chute, a sliding detector, a coil and a driving assembly, wherein the sliding chute isformed in the fixing support, the sliding detector can detect the edge thickness of the strip coil through the detection opening and slide along the sliding chute, the coil is arranged in the slidingchute and is connected with the sliding detector to form a variable resistance circuit and is used for feeding back the position of the sliding detector, the driving assembly is connected to the sliding detector and used for driving the sliding detector to slide along the sliding chute; and the coil and the sliding detector are electrically connected to the controller. The device can be used for simply and effectively monitoring the residual thickness of the strip coil at different positions.

Description

technical field [0001] The invention relates to the technical field of tape processing, in particular to a tape unwinding device. Background technique [0002] In the sheathing process of optical cable manufacturing, the tape coil is fixed on the chassis of the tape rack for use. Before the coils are used up, a welding operation needs to be performed on the old and new coils. At this time, it is necessary to increase the speed of the tape rack, quickly store the remaining tape coils in the tape storage box on the production line, and complete the disk changing and welding operations before the tape in the tape storage box is used up, otherwise it will affect production efficiency and even A quality accident occurs. [0003] However, due to the differences in production speed and personnel operating proficiency, it is difficult to achieve precise control of the production process in this belt changing method. [0004] In order to remind the operator to change the belt in t...
