Specific embodiment
Understand to make the object, technical solutions and advantages of the present invention clearer, with reference to embodiment, the present invention is made
Further to be described in detail, exemplary embodiment of the invention and its explanation are only used for explaining the present invention, are not intended as to this
The restriction of invention.
Embodiment 1：
As shown in Figure 1 and Figure 2, a kind of process units with fixed length cutting PVC pipe, including precession handle 1, motor, electricity
The main shaft of machine 8 is connected with precession handle 1, and precession handle 1 is connected with telescopic rod 2, telescopic rod 2 with driving axis connection, drive shaft with
Specific 3 connection of knife, knife specific 3 are arc-shaped structure, and one end of knife specific 3 is with driving axis connection, the other end connection of drive shaft
There is cutting tool 4, cutting tool 5 is fixed on the driving shaft by fastener 5, and the other end of knife specific 3 is equipped with circular arc locating piece
6, circular arc locating piece 6 is excellent arc structure, and plastic pipe 8 is passed through in the cavity of circular arc locating piece 6；The plastic pipe 8 is placed in
It drawing on crawler belt 9, traction crawler belt 9 is mounted in supporting table 10, and traction crawler belt 9 is connected with the second motor, and on traction crawler belt 9
Rice counting wheel 11 is installed, rice counting wheel 11 is coaxially fixedly connected with encoder 12, and encoder 12 is electrically connected with PLC controller 13.
The main function of motor 8 is in the present embodiment, and the main shaft of motor 8 is connected with precession handle 1, so as to drive precession hand
Handle 1 moves, therefore, the structure that 8 structure of motor here can be known to the skilled person.
Precession handle 1 is connected with telescopic rod 2, telescopic rod 2 itself play an important role of it is flexible, can under the driving of motor 8, to
Close to the movement of the direction of circular arc locating piece 6.And telescopic rod 2 and driving axis connection, the width of drive shaft are less than the width of telescopic rod,
Cutting tool 5 is connected in driving the tip of the axis, cutting tool 5 is strip Straight blade structure, can be directly used for cutting plastics
Tubing.Wherein, knife specific 3 is arc-shaped structure, and its one end passes through the through hole set in drive shaft, and the end is to be leaned in drive shaft
One end of nearly connection cutting tool 5, knife specifically may pass through the through hole, and is fixed with drive shaft.
Circular arc locating piece 6 is also associated in the end of knife specific 3 in the present embodiment, circular arc locating piece 6 is in cutting tool
It is oppositely arranged.The fastener 5 is bolt or pin configuration, and is hollow circular tube structure in view of the structure of plastic pipe, directly
Footpath is different, in order to reach location structure of the circular arc locating piece to plastic pipe, and beneficial to the cutting of cutting tool, therefore, sets
The circular arc locating piece 6 is made of multigroup arc structure, and is overlapped successively from bottom to up, and the chord length of circular arc is sequentially reduced, can
According to the diameter of plastic pipe, the circular arc chord length of selection overlapping installation, is excellent circular arc or bad arc structure, consequently facilitating plastics
Tubing is placed in the circular arc locating piece 6.
And the knife specific 3 described in the present embodiment is semi arch structure, main function is the fixation being beneficial to circular arc locating piece,
Realize fast operating.
By setting PLC controller in the present embodiment, for existing controller structure, model YL77-EPX-410, metering
It takes turns and is arranged on traction crawler belt, being arranged on traction, above crawler belt can also be arranged on the lower crawler belt of traction, can equally play the role of meter length, but
Here selection is arranged on the upper crawler belt of traction, and that rice counting wheel can be made to be contacted with crawler belt is more stable, can also play the role of compression crawler belt, make
It is more steady to draw crawler belt colliery carries tubing.When drawing crawler belt operation, tubing follows traction crawler belt to be synchronized with the movement together, and counts
Rice wheel is contacted with traction crawler belt, is rotated in traction under the influence of crawler belt linear motion, so as to measure tubing
The length of feeding.
It is improved in the operation calculation procedure of PLC controller, selects Siemens S7-200PLC here to encoder
Pulse carries out step-by-step counting and sequential operation, and user only need to arbitrarily input an encoder coefficient A and required in man-machine interface
Cutting Length setting value B, when surface trimming goes out a tubing (assuming that the pipe length being cut into be C), it is assumed that tubing 4 is grown
Spend for C when, the length that corresponding rice counting wheel 2 is walked is X1 (unknown number), from rice counting wheel 2 and the mounting characteristics of encoder, metering
Wheel 2 and the umber of pulse of encoder 3 are there are linear relationship, that is, having the umber of pulse actual value X2=a*X1 of encoder 3, (a is solid for one
Determine coefficient).That be now to calculate is accurate encoder coefficient Y, i.e., one accurate encoder coefficient can cut tubing
Actual value is cut equal to 4 setting value of tubing, two equatioies can be obtained by above-mentioned condition：C=X2*A=(a*X1) * A and B=X2*Y
=(a*X1) * Y.Accurate encoder coefficient Y=(A*B)/C can be calculated by equation, because A, B, C are given values.It therefore can
Calculate accurate encoder coefficient.
The present invention using the above method, avoid one go out in more pipe production lines to occur Cutting Length not to the phenomenon that go out
It is existing, it is only necessary to a tubing physical length having been cut out to be inputted, then by PLC program by the encoder of existing inaccuracy
Coefficient is changed to accurate encoder coefficient, and the next pipe length being cut into will be automatically consistent with setting value.Work as needs
When changing tubing Cutting Length, it is only necessary to Cutting Length setting value be arranged to required length, without changing encoder
Coefficient.
Above-described specific embodiment has carried out the purpose of the present invention, technical solution and advantageous effect further
It is described in detail, it should be understood that the foregoing is merely the specific embodiments of the present invention, is not intended to limit the present invention
Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
