Summary of the invention:
The objective of the invention is to provide for the prior art weak point a kind of rational in infrastructure, accurate positioning, can realize the length measuring device for packed bag of horizontal packer of automation mechanized operation.
The objective of the invention is to realize by following measures: a kind of length measuring device for packed bag of horizontal packer, comprise that one be used for to receive, compression, discharges the drivable or electricity consumption of the compression chamber, of waste or with the compacting part of hydrostatic drive or mechanical drive mode, it is characterized in that also having signal gathering unit, signal processing unit; Wherein:
Described signal gathering unit is comprised of bar shaped seam, extension spring, ratchet, ratchet erecting frame and the base of compression chamber's loam cake, described ratchet is installed on the ratchet erecting frame by bearing, base is fixed in the compression chamber and covers, ratchet erecting frame one side and base is articulated and connected, opposite side hangs with extension spring, the other end of extension spring hangs in the compression chamber and covers, and ratchet inserts in the bar shaped seam of compression chamber loam cake under the pulling force effect of extension spring, the screens of the ratchet gear teeth is on waste;
Described signal processing unit is comprised of inductance type proximity transducer, pulse-scaling circuit, micro controller system, driver module, power element relay, the signal of inductance type proximity transducer is through pulse counting circuit access micro controller system signal input part, driver module input end and micro controller system signal output part join, and the output port of driver module and actuating unit relay join;
Described inductance type proximity transducer is installed in ratchet circumferential edges position, the counting ratchet rotor wheel number of teeth.Good effect of the present invention is: the length measuring device for packed bag of horizontal packer that the present invention proposes, its advantage is as follows: the present invention is installed in ratchet circumferential edges position by proximity transducer, record the ratchet gear teeth and rotate the number of teeth, by provided the instruction of the power element actuating of relay after the signal input unit processing by the user program that is stored in micro controller system, realized full-automatic control.The present invention is rational in infrastructure, easy for installation, accurate positioning, can promote the use of.

The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated: Fig. 1~Fig. 2 has provided embodiment of the invention signal gathering unit structural representation and signal processing unit functional-block diagram.Among the figure, a kind of length measuring device for packed bag of horizontal packer, comprise that one be used for to receive, compression, discharges the drivable or electricity consumption of 1, one of the compression chamber of waste or with the compacting part 8 of hydrostatic drive or mechanical drive mode, signal gathering unit, signal processing unit; Described signal gathering unit as shown in Figure 1, its bar shaped seam 9, extension spring 2, ratchet 4, ratchet erecting frame 3 and base 6 by compression chamber's loam cake forms, described ratchet 4 is installed on the ratchet erecting frame 4 by bearing, base 6 is fixed in the compression chamber 1 and covers, ratchet 4 erecting frames, one side and base 6 is articulated and connected, opposite side hangs with extension spring 2, the other end of extension spring 2 hangs in the compression chamber 1 and covers, and ratchet 4 inserts in the bar shaped seam 9 of compression chamber's 1 loam cake under the pulling force effect of extension spring 2, ratchet 4 gear teeth screens are on waste 7.
Described signal processing unit is comprised of inductance type proximity transducer 6, pulse-scaling circuit 10, micro controller system 11, driver module 12, power element 13 relays, the signal of inductance type proximity transducer 5 is through pulse counting circuit 10 access micro controller systems 11 signal input parts, driver module 12 input ends and micro controller system 11 signal output parts join, and the output port of driver module 12 and actuating unit 13 relays join; Described inductance type proximity transducer 5 is installed in ratchet 4 circumferential edges positions, the counting ratchet rotor wheel number of teeth.
Principle of work of the present invention is as follows: the pulling force of the ratchet of signal gathering unit of the present invention by extension spring, drives ratchet and rotates on waste with certain positive pressure screens when pushing ahead under the effect of waste at compacting part.By the inductance type proximity transducer counting ratchet rotor wheel number of teeth that is installed in ratchet circumferential edges position.The inductance type proximity transducer is by HF oscillation, detection, amplify, trigger and the output circuit composition, its oscillator sensor detection faces produces an alternating electromagnetic field, when ratchet gear teeth proximity transducer detection faces, in the ratchet gear teeth, produce eddy current and absorbed the oscillator energy, make the oscillations failure of oscillation, oscillator vibration and these two kinds of states of failure of oscillation, change through the pulse counting circuit, shaping, amplify and convert the binary switch signal to, behind power gain, input to again micro controller system, processed by the user program that is stored in the micro controller system, be the length that waste moves with the number conversion of ratchet turning gear, micro controller system sends signal instruction after reaching certain-length, driver module is carried out the signal instruction that micro controller system sends, and the actuating of relay that drives actuating unit stops the action of compacting part.
The above has described embodiments of the present invention by reference to the accompanying drawings, and the structure that embodiment provides is not construed as limiting the invention, and those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain in this area.
