Lettering block heating controller based on wireless temperature sensor and method

Abstract

The invention discloses a lettering block heating controller based on a wireless temperature sensor and a method and relates to the field of inkwriter equipment of a sheath process in a communication optical cable production process. The controller comprises the wireless temperature sensor, a programmable controller and a temperature control relay control loop. The wireless temperature sensor comprises a sending device, a receiving device, a temperature display instrument, a protocol converter and temperature measurement probes and is fixedly installed on an inking wheel of an rotary inkwriter; the inkwriter comprises a meter counting disc and a lettering disc, the meter counting disc is provided with a lettering block and heating blocks, and the lettering disc is provided with a base; the base is provided with a crescent-moon-shaped plate and an installation block; and the temperature measurement probes are installed in the heating blocks of the inkwriter, the heating blocks are installed on the crescent-moon-shaped plate of the rotary inking wheel, the sending device is fixedly installed on the installation block, and the installation bloc is fixed to the base. By means of the lettering block heating controller based on the wireless temperature sensor and the method, heating of the lettering block on lettering rotating equipment can be precisely controlled.

Description

technical field [0001] The invention relates to the field of printing machine equipment in the sheath process in the production process of communication optical cables, in particular to a printing block heating controller and method based on a wireless temperature sensor. Background technique [0002] In the production process of the optical cable, a printing machine is needed in the sheathing process to print the mark and meter length on the optical cable. The traditional printing machine is a printing wheel with a circumference of 1 meter. A printing block heating device is installed on the printing wheel. Between the outer sheaths of the optical cable, when the heated printing block is rolled over the printing ribbon, the corresponding word mark on the printing block is printed on the outer sheath of the optical cable through the printing ribbon. [0003] Because the printing wheel rotates during the production process, the heating block installed on the printing wheel a...

Problems solved by technology

[0003] Because the printing wheel rotates during the production process, the heating block installed on the printing wheel also rotates with the printing wheel, and the heating part of the circuit is connected to the electric control circuit by the slip ring on the printing wheel, because the installation Space problem, the number of slip ring groups is limited, the traditional heating method slip ring wiring is only for heating cables, and a relay with adjustable heating pulse time is used to control the heating on and off; the heating time is adjusted manually, and the entire heating is adjusted to be on Ring control, the heating time is adjusted according to the appearance of the printing, the actual temperature control of the printing block is not accurate

If the temperature signal of the printing block is collected through the slip ring wiring, the temperature measurement signal is mv or a resistance signal with a small resistance value. Because the slip ring part is a rotating device, the temperature collection is inaccurate due to the interference of the contact part, and the temperature often occurs. Collection disconnection problem
