The driving part comprises a first fixing rod arranged on the driving groove, a first gear rotatably arranged on the first fixing rod, an electric sliding block used for driving the first gear, a first tooth groove arranged on the electric sliding block, a second gear arranged on the first gear and a second tooth groove arranged on the moving frame; the first tooth slot may be engaged with the first gear; the second tooth groove is meshed with the second gear.
After the plastic pipe is placed on the moving frame for preliminary limiting, the electric sliding block is started, the first tooth grooves in the electric sliding block are meshed with the symmetrical first gears, the first gears are rotated, and therefore the second gears are driven to rotate. The removal frame of two symmetries all removes through same electronic slider, so can keep in step to all can be the same in the hot melt, can not appear one end and the different condition of other end processing, thereby make the welded quality of plastic tubing improve, let the hot melt region can not appear the defect, prevent to snap and appear with regard to disconnected problem, improve the rigidity of the plastic tubing after the butt fusion.
The limiting component comprises first sealing grooves symmetrically arranged on the guide block, first extrusion blocks movably arranged on the first sealing grooves, and lugs symmetrically arranged on the movable frame; the first sealing groove is arranged on the movable frame, the first sealing groove is arranged on the first sealing groove in a sliding mode, and the two ends of the first sealing groove are respectively connected with the first sealing groove and the second sealing groove; the lug can push the first extrusion block; the first limiting block can clamp the plastic pipe; the gas in the first sealing groove can enter the limiting groove through the vent pipe.
When the movable frame moves, the convex block fixedly connected to the movable frame also moves to push the first extrusion block, so that gas in the first sealing groove enters the limiting groove through the vent pipe, the air pressure in the limiting groove is increased, the first limiting block is pushed, and one end of the limiting block comes out of the limiting groove; thereby further carry on spacingly to the plastic tubing, improve the stability of plastic tubing, guarantee the integrality in the cutting, the problem of cutting surface unevenness can not appear to improve the quality in back hot melt and butt fusion.
The cutting part comprises a cutting groove arranged on the movable frame, a cutting plate arranged on the cutting groove, a positioning block arranged on the cutting plate, a spring arranged on the cutting groove and used for limiting the cutting plate, a second fixed rod arranged on the cutting plate and a cutting knife arranged on the second fixed rod in a rotating mode.
Put the plastic tubing on removing the frame, promote the plastic tubing and draw close toward the centre, plastic tubing one end is pushing up the cutting board, let the cutting board come out partlyly from cutting the cut groove, go on pressing from both sides tightly the plastic tubing, after spacing good, rotate the cutting knife, the one end that needs the cutting to the plastic tubing gets off, make this one side become level and smooth, can prevent impurity in the plastic tubing, influence the quality behind the plastic tubing hot melt, thereby improve the efficiency of hot melt, prevent the plastic tubing after the butt fusion, the region of hot melt is participating in impurity and reducing the rigidity, the condition about breaking appears one folding, finally, the quality is improved.
The limiting component also comprises a supporting block arranged on the second fixing rod, a guide groove arranged on the supporting block, a second limiting block movably arranged on the guide groove, a limiting spring used for resetting the second limiting block, a first arc angle arranged on the second limiting block, an elastic rope arranged on the moving frame and a stabilizing block arranged on the elastic rope; the second limiting block can be in contact with the plastic pipe at the initial position.
