Abstract

The utility model relates to a magnetic controlling tightness monitor controlled by the tightening power of the bundling belt of the bundler, comprising a switch circuit and a permanent magnetic sheet, wherein, the permanent magnetic sheet is a round magnetic sheet whose one surface is filled with a plurality of uniformly distributed magnetic fields, and the round magnetic sheet is integrally connected with a belt bundling and pressing wheel shaft; a magnetic inducting coil for controlling the on-off is arranged in the switch circuit. The permanent magnetic sheet is arranged on the opposed side of the magnetic inducting coil, and thus the magnetic inducting coil is positioned in the magnetic fields of the permanent magnetic sheet. When the belt pressing wheel is stopped to operate, the circuit is switched on, the control circuit of the bundler is started, and the next operation is performed. The structure of the monitoring device of the tightening power of the bundling belt is simplified. Failure hardly occurs.

Description

Magnetic controlling tightness monitor for bundler
The utility model belongs to package packing machine, and particularly the magnetic control of banding machine tie tightening force control tightens up controller.
The tie pinch roller is by a friction drive wheel in banding machine, and when tie tightening force during greater than the friction of frictional wheel, pinch roller stall and drive wheel skids utilizes this principle design tie tightening force control setup.The tightening force detection device of prior art is mechanical device, and by many mechanical parts, form as wheel, bar and conveyer mechanism, structure is very complicated, occupies certain space in machine, and very easily is out of order, and keeps in repair very difficult.
The purpose of this utility model is that the magnetic control that proposes a kind of alternative mechanical device tightens up detection device technical scheme, adopts magnetic control technology to make apparatus structure simple, not easy break-down.
Content of the present utility model comprises switch circuit and permanent magnetism sheet, the permanent magnetism sheet is the round magnetic sheet that one side is filled with some groups of well-distributed magnetic fields, the circle magnetic sheet connects with tie belt wheel one, the magnetic induction loop that the control break-make is arranged in the switch circuit, the permanent magnetism sheet is located at the magnetic induction loop opposite, and magnetic induction loop is among the magnetic field of permanent magnetism sheet.Switch circuit is made up of three diode D, three aerotron GB, stabilivolt D, magnetic induction loop L and the resistance R that matches, capacitor C, and its circuit connecting relation is:
Cathode power supply meets D 1Positive pole, D 1Bear and C 1Just, R 1, R 2, R 4Join, C 2Just join with L one end, C 2Bear and R 1Other holds, GB 1C joins, GB 1B and R 2Other holds, stabilivolt D 2Just continuous, D 2Bear and C 3Just reaching GB 2C links to each other, GB 2B and R 4Hold in addition and stabilivolt D 3Negative connects, D 3Just and GB 3C links to each other, GB 3B and D 4Negative connects, C 1Negative, L holds in addition, R 3Other holds, C 3Negative, GB 2A, GB 3A, D 4Just equal connecting to neutral (power cathode).
Characteristics of the present utility model are to be wholely set a permanent magnetism sheet that even laying permanent magnetic field arranged, to cooperate the magnetic strength circuit with belt wheel.When the pinch roller stall, circuit is logical, starts the banding machine control circuit, carries out further work.Make tie tightening force detection simplified, be difficult for et out of order.
Embodiment of the present utility model is as shown in drawings:
Fig. 1 is a permanent magnetism sheet constructional drawing, and wherein 1.1 is front views, the 1.2nd, and the side-looking partial cross sectional views;
Fig. 2 is a magnetic induction detection circuit diagram;
Number in the figure is represented:
1, permanent magnetism sheet 2, permanent magnetism sheet center
D 1, D 2, D 4, diode D 3, stabilivolt
C 1, C 2, C 3, electric capacity
R 1, R 2, R 3, R 4, resistance
GB 1, GB 2, GB 3, aerotron L, magnetic induction loop
Accompanying drawing is specified the utility model in conjunction with the embodiments:
Permanent magnetism sheet 1 is a circular lamellar body, is filled with well-distributed magnetic field on the surface.Permanent magnetism sheet center 2 and belt wheel one.Permanent magnetism sheet 1 interlock rotation when pinch roller changes, its Surface field district produces rotating field, and the magnetic induction loop L in the circuit is in the magnetic field of permanent magnetism sheet 1.In the magnetic strength circuit, when 1 rotation of permanent magnetism sheet, coil L cutting magnetic line produces current impulse, capacitor C 2Lead to, at this moment circuit working end no-voltage.When 1 stall of permanent magnetism sheet, coil 1 does not produce current signal, then aerotron GB 1, GB 2Operating signal current is amplified through stabilivolt D 3, start aerotron GB 3The c end makes the circuit working end produce operating voltage, and is logical to start the banding machine control circuit, starts working.
The design's detection device adopts magnetoelectricity principle producing device, and is simple in structure, replaces mechanical device fully, and reliable.The design's detection device can be made separately, is used on other similar mechanical device.
