Description

A ZL29 Filter Rod Forming Machine Refrigeration System Water Circulation Detection Device

technical field

The utility model relates to the technical field of cigarette machinery and equipment, in particular to a water circulation detection device for a refrigeration system of a ZL29 filter rod forming machine.

Background technique

Among the current cigarette forming machines in the cigarette industry, the ZL29 filter rod forming machine consists of 3 cooling circulation loops. The lower part of the bong, each drive device and gear transmission device of the YL29 filter rod forming machine are cooled. The heat is transferred via the cooling water to the water heat exchanger inside the machine and from there to the external circulation loop. At present, the wrapping workshop is produced in two shifts, and the night shift is suspended for maintenance. When the middle shift is finished for maintenance, the operator will manually close the refrigeration circulating water valve and the "cooling device" button on the man-machine interface to ensure that the entire refrigeration system stops running. However, in actual operation, the operator closed the cooling water valve, but did not press the "cooling device" button, which would cause the entire circulating water to dry in a static state, resulting in damage to the refrigerator E73. The only method is to replace the refrigerator, because the disassembly and installation process of the refrigerator is complicated, requires a lot of manpower and time, and the refrigerator is relatively expensive, so the maintenance cost of the equipment is increased and the maintenance efficiency is reduced.

When the machine is running normally, the high level of I.1 is valid, and the coil of the relay K0.1 is de-energized, then the normally open contact of K0.1 is disconnected, and I.1 becomes the low level.

As a further improvement of the present invention, the refrigeration device includes a compression motor M1, a compression motor air switch Q1, a compression motor contactor K1, a pump motor M2, a pump motor air switch Q2, and a pump motor contactor K2, wherein the refrigeration device power input The wires are connected to the air switch Q91 and contactor K0 outside the refrigeration device in turn, and then respectively connected to the compressor motor M1, the compressor motor air switch Q1, the compressor motor contactor K1, the pump motor M2, the pump motor air switch Q2, and the pump motor contactor inside the refrigeration device. A contactor K2, the contactor K0 is installed outside the refrigerating device to pull in or turn off the motor of the refrigerating device.

Compared with the prior art, the beneficial effects of the present utility model are:

The utility model installs a target piece type water flow switch sensor on the water outlet pipe of the water heat exchanger of the AF opener of the ZL29 filter rod forming machine, and checks whether there is water flow in the water outlet pipe of the water heat exchanger in real time. Because the sensor sends a switch signal, this signal can be directly used to turn on and off the corresponding contactor, and this signal can also be incorporated into the corresponding PLC signal input module, so as to achieve the shutdown effect and have corresponding shutdown information. .
