Description
Technical field
The utility model relates to a kind of device that measures profile length, and the device especially for metering pipe length on the plastic tube product line belongs to field of measuring technique.
Background technology
On plastic tube product line, the tubing that processes cuts automatically according to certain-length, needs to be equipped with length measuring device.At present, the length measuring device that generally uses is made up of scrambler grating, photoelectric tube, shaping pulse and counting circuit etc.Grating detection wheel in this device and the transmission of finished product tubing direct friction are to obtain driving force, and photoelectric tube output encoder pulse signal is counted to shaping amplification and counting circuit, and provides instant length data.This class device generally also will be counted the control device that long signal offers production line simultaneously, send signal, incising pipes to cutting off tool when meter long data meter is expired setting value.The produced on-site process shows, this general length measuring device has some problems, mainly be when some disturbing factor causes the tubing vibration, grating detection wheel and tubing are skidded, make the pulse number generation deviation of length measuring device output, cause the pipe sizing that is cut to depart from the setting size.What more mostly occur in the practice is that pulse number reduces, and makes the tube length of cutting be longer than the long size of setting, thereby brings loss to production.
Summary of the invention
The utility model is used to solve the defective of above-mentioned prior art and a kind of accurate tubing length measuring device of metering that can effectively avoid vibrating and skid influence is provided.
The alleged problem of the utility model solves by the following technical programs:
The accurate tubing length measuring device of a kind of metering, form by fifth wheel, magneto-dependent sensor and executive circuit, described magneto-dependent sensor and executive circuit are electrically connected, its special feature is: fifth wheel 4 is fixed on the axle head of tubing traction engine crawler belt main shaft, described fifth wheel is the permeability magnetic material gear, the sensitive element of magneto-dependent sensor is positioned at by the fifth wheel side, and distance is 0.5～1 millimeter between the two.
The accurate tubing length measuring device of above-mentioned metering, the profile of tooth of described fifth wheel is a rectangle, 0.5 millimeter of transverse tooth thickness; 1.7～2 millimeters of space widths; 3～4 millimeters of tooth depths; The fifth wheel axial width is more than or equal to 5 millimeters.
The utility model improves at error in dipping easily appears in common length measuring device under vibration and factor affecting such as skid problem, fifth wheel after the improvement and tubing traction engine crawler belt main shaft are fixed, are rotated synchronously with main shaft, and magneto-dependent sensor passes through to detect the facewidth, tooth pitch output pulse signal and realizes the long and control of meter to executive circuit after treatment.The utility model can effectively overcome working environment to counting the influence of long precision when satisfying the long precision of meter, non-slip, meter is long accurately, stable and reliable working performance, has characteristics such as simple in structure, easy for installation in addition.
Description of drawings

Fig. 2 is the electric theory diagram of meter long circuit part.
Each parts label is as follows among the figure: 1. tubing; 2. tubing traction engine; 3. tubing traction engine crawler belt main shaft; 4. fifth wheel; 5. crawler belt; 6. magneto-dependent sensor; 8. Athey wheel; T. triode; J1. relay.
Embodiment
Referring to Fig. 1, the utility model is made up of fifth wheel 4, magneto-dependent sensor 6 and executive circuit, and fifth wheel is made by permeability magnetic material (as iron and steel, ferrite etc.), and magneto-dependent sensor and executive circuit are electrically connected.Fifth wheel is concentric fixing with the main shaft 3 of tubing traction engine Athey wheel 8, rotates synchronously with main shaft.Steady because of 2 runnings of tubing traction engine, it can not be subjected to the influence of tubing vibration, so the rotation of fifth wheel is steady equally.At the other magneto-dependent sensor 6 of installing of fifth wheel side, require its adjustment notch should be perpendicular to gear face, distance should be advisable with 0.5～1 millimeter within the magneto-dependent sensor sensing range.For satisfying the long accuracy requirement of meter, 0.5 millimeter of the transverse tooth thickness of fifth wheel; 1.7～2 millimeters of space widths; 3～4 millimeters of tooth depths; The fifth wheel axial width is more than or equal to 5 millimeters, and profile of tooth is a rectangle, and the profile of tooth geometric profile sudden change of rectangular teeth helps forming waveform signal preferably.
Executive circuit in the utility model is made up of triode T and relay J 1, the base stage of triode is connected to the signal output part of magneto-dependent sensor, signal is through amplifying the rear drive actuating of relay, normally opened contact J1-1 by relay connects correspondent control circuits, such as the control circuit that cuts off tubing, finish and cut off action.Magneto-dependent sensor in the utility model can be selected the series of products of CS or CSH type, as CS-1015, CS-1215, CSH-1215, CSH-1615, or the like.The magneto-dependent sensor of this model is integrated in sensitive element, coding circuit, signal shaping, amplifying circuit etc. in the chip, uses easily.
The course of work of the present utility model is as follows: tubing traction engine crawler belt main shaft drives crawler belt 5 motions, crawler belt clamping tubing 1 moves, the fifth wheel of main shaft drive meanwhile rotates synchronously, the tooth of fifth wheel and teeth groove alternately pass through magneto-dependent sensor, thereby periodically change magneto-electric induction pulse signal in the magneto-dependent sensor, pulse signal is transferred to executive circuit, plays the long control action of meter thus.
