Indian automatic baler strapping length metering device

Horizontal baler strapping length measuring device, including a compression chamber for receiving, compressing, and discharging waste, a compression component that can be driven or used by electricity or hydraulic or mechanical transmission, signal acquisition unit, Signal processing unit.

The signal acquisition unit is composed of a strip slit on the upper cover of the compression chamber, a tension spring, a ratchet, a ratchet mounting frame and a base, and the signal processing unit is composed of an inductive proximity sensor, a pulse counting circuit, a single-chip microcomputer, a driving module, and an actuator The inductive proximity sensor is installed on the peripheral edge of the ratchet wheel and counts the number of teeth of the ratchet wheel.
The advantages of the utility model are as follows: the utility model is installed at the peripheral edge of the ratchet wheel through the proximity sensor, and the number of teeth of the ratchet wheel teeth is measured. After processing by the signal input unit, the user program stored in the single-chip microcomputer gives instructions for the action of the actuator relay. Realize fully automated control.
Wherein: the signal acquisition unit is composed of a strip slit on the upper cover of the compression chamber, a tension spring, a ratchet, a ratchet mounting frame and a base, the ratchet is mounted on the ratchet mounting frame through a bearing, and the base is fixed on the upper cover of the compression chamber On the upper side, one side of the ratchet mounting frame is hingedly connected to the base, and the other side is hung with a tension spring. The other end of the tension spring is hung on the upper cover of the compression chamber. The ratchet is inserted into the strip shape of the upper cover of the compression chamber under the tension of the tension spring. In the seam, the teeth of the ratchet wheel are stuck on the waste.

The signal processing unit is composed of an inductive proximity sensor, a pulse counting circuit, a single-chip microcomputer, a driving module, and an actuator relay. The signal of the inductive proximity sensor is connected to the single-chip signal input terminal through the pulse counting circuit, and the driving module input terminal and the single-chip signal The output terminal is connected, and the output port of the driving module is connected with the actuator relay; the inductive proximity sensor is installed at the peripheral edge of the ratchet wheel, and the number of teeth of the ratchet wheel is counted.
NKBALER automatic baler has simple structure, stable performance, reliable quality, convenient operation and high degree of automation. It is your best choice.
