The control 3213 includes an active version, a passive version and a linked version, the active version: before the equipment is operated, the extending amount of the abutting roller 3212 is adjusted according to the diameter length of the PVC pipe; passive version: the extending amount of the abutting roller 3212 is controlled by elastic materials, so that the adjustment by people is not needed, and the labor is saved. Make the PVC pipe can move ahead with butt gyro wheel 3212 butt in the operation process, change into the rolling friction with butt gyro wheel 3212 from the sliding friction with accepting board 321, thereby the resistance has been reduced, the pressure in the feed arrangement 1 course of work has been reduced, guarantee feed arrangement 1's life, moreover can also guarantee that the PVC pipe steadily removes and inserts in the insertion groove 3341, avoid because the PVC pipe is flagging under the action of gravity, thereby the condition in the unable insertion groove 3341 takes place.

The abutting roller 3212 includes an active roller 32121 and other passive rollers 32122 located on the receiving plate 321 and closest to the feeding device 1, the control member 3213 includes an elastic member 32131 for controlling the active roller 32121 to extend and retract along the depth direction of the roller groove 3211 and a linkage member 32132 for controlling all the passive rollers 32122 to extend and retract along the depth direction of the roller groove 3211, the roller grooves 3211 corresponding to the passive rollers 32122 are communicated with each other, the linkage member 32132 includes a linkage plate 321321 and a plurality of linkage rods 321322 disposed on the linkage plate 321321 and connected to the center of the passive rollers 32122, the elastic member 32131 is provided with a sensing device 32133 for sensing the position of the active roller 32121, the linkage member 32132 is provided with a sensing driving device 32134 for controlling the passive rollers 32122 to move to the same height as the active roller 21 according to a sensing signal of the sensing device 32133, when the sensing device 32133 senses the position change of the driving roller 32121, the sensing driving device 32134 drives the linkage plate 321321 to move along the depth direction of the roller groove 3211. This is a linked version of the above, with design benefits combining the benefits of both active and passive versions and discarding their disadvantages: 1. the active version is cumbersome to operate; 2. the passive version butt gyro wheel 3212 can have ascending driving force to the PVC pipe, and more butt gyro wheels 3212 its driving force altogether is bigger, can lead to causing certain degree of buckling to the PVC pipe of the exit end position of feed arrangement 1, influences final product. This linkage version only has active gyro wheel 32121 to have the reaction force to the PVC pipe, and this reaction force is very little, can not appear influencing final product, and the removal that synchronous stretch out or retract is realized through induction drive 32134 (cylinder or motor) to remaining passive gyro wheel 32122 to do not cause the reaction force but can active gyro wheel 32121 the same with the PVC pipe butt. The sensing device 32133 can be a sensor according to the pressure, the compression stroke can be converted by adding the pressure and the elastic coefficient of the elastic element 32131, or a position sensing sensor, which can determine the moving stroke by sensing the position of the active roller 32121.

The device adopting the PLC control system can control the start and stop of the device through the start and stop of the switch, inputs a PVC pipe in-place signal into the detection mechanism, and the control system can output a cutting signal of the cutter 21 and automatically cut the PVC pipe in a proper direction and at a proper rotating speed. The PLC control system can also inform an operator of the equipment condition through an indicator light and timely stop the equipment through a safety mechanism to protect personnel safety. The PLC control system can set parameters and display operation data on an operation interface. Such as setting of working time of each action, speed of operation of the cutter 21, and display of finished product count. The running state, such as the working condition of the motor and the air pressure value of the air cylinder, can be monitored to judge whether the equipment is normal or not, and if the running fails, the equipment can be stopped in time and used as the basis for judging the failure.
