The clamping component includes the first connecting plate 27, fixed plate 35, the second connecting plate for being fixed at 26 front end face of sliding block 36, two folder, the fixed plate 35 are fixed at 24 upper surface of rack housing, and second connecting plate 36 is fixed at fixation On the downside of 35 rear end face of plate, two folder is respectively fixedly disposed at 36 upper surface of 27 upper surface of the first connecting plate and the second connecting plate.

The folder of first connecting plate, 27 upper surface includes two second for being fixed at 27 upper surface left and right sides of the first connecting plate 328, two the second telescopic blocks 29 of square tube, reset spring, clamping plate 31, two briquettings 32, top plate 33, two indents, square 34, described two A second telescopic block 29 is movably separately positioned in two second square tubes 328, and the reset spring is fixed at two Between 328 lower end wall of second telescopic block 29 and second square tube, the clamping plate 31 is fixed at 29 upper end of the second telescopic block, described Two briquettings 32 are fixed at 31 upper surface left and right sides of clamping plate, and the top plate 33 is fixed at 26 front end face of sliding block, and described two Indent is arranged in 33 lower surface left and right sides of top plate and matches with two briquettings 32, and the square 34 is fixed at 31 following table of clamping plate Face, two folder is arranged symmetrically.

33 left and right sides of top plate on the folder is respectively set there are two the first threaded hole, and the clamping plate 31 on the folder is left Right side is respectively set there are two the second threaded hole, and first threaded hole is to be connected to setting, first spiral shell with the second threaded hole Pit and the second threaded hole are fastened by screw bolt and nut, and a rubber block 900 is provided between the top plate 33 and clamping plate 31；It will PVC pipe on extruder is placed between two traction devices, is clamped PVC pipe by two traction devices, starts motor, Motor drives conveyer belt to move right, and conveyer belt drives two traction devices to move right, so that PVC pipe be driven to move right It is dynamic；PVC pipe is clamped by the rubber block on two traction devices, it can be by the appearance of PVC pipe by the deformation of rubber block Face is close to the surface of rubber block, so as to clamp PVC pipe, avoids making PVC pipe in the process of moving and leading Leading-in device is loosened and can not persistently be moved right；Cylinder starting drives inclined plate 28 to be moved left and right, and the front end face of inclined plate is set It is set to inclined-plane, the rear end face of sliding block 26 is set as inclined-plane, thus when conveyer belt is mobile to make sliding block 26 be in contact with inclined plate 28, tiltedly Plate 28 is moved forward with movable slider 26, and sliding block 26 is moved forward with carry-over bar 25, so as to adjusting slider 26 and fixed plate 35 The distance between, so as to according to the pipe diameter size adjustable range of PVC pipe, so as to clamp the pvc pipe of different tube diameters Material, to keep the application range of equipment more extensive；Inclined-plane is set far from the end surface of conveyer belt by skewback, so as to make When skewback and arc panel contact, arc panel will drive the close transmission belt surface movement of skewback, and skewback drives traction device close to biography It send belt surface to move, when far from arc panel, is resetted traction device by spring, so as to be incited somebody to action in the corner of conveyer belt The traction device of upside moves up, and the traction device of downside moves down, thus avoid side in corner's rubber block with The surface of PVC pipe contacts and is kept rubber block easily damaged by frictional resistance, when traction device is moved to horizontal position, two A traction device can be drawn close and clamp PVC pipe；Rubber block can be made to be pushed down into pressure in the extruding force of two briquettings by two indents In slot, so as to can be avoided the sliding of rubber block progress all around, so as to be clamped rubber block, to make to lead Rubber block will not loosen when leading-in device transports conveyer belt, to keep equipment operation more stable；It can by the setting of reset spring Rubber block is resisted when replacing rubber block, consequently facilitating later use screw bolt and nut is tightened.

A straight panel 35 is fixedly connected between square 34 on two folder；By pulling straight panel 35 can be by bolt Clamping plate is pulled with after nut dismounting, consequently facilitating rubber block taking-up is replaced.

The rubber block needs to be customized according to size in factory.

First electromagnet, the second electromagnet can be bought in the market.

Working principle: rotating the first handwheel 213 by hand, and the first handwheel 213 drives second gear 13 to rotate, second gear 13 First gear 6 is driven to rotate, first gear 6 drives the rotation of the first screw rod 3, so that rectangular slab 4 is driven to move downward, so as to Two traction devices are moved adjacent at the aperture center of extruder, the PVC pipe on extruder is placed on two traction devices Between, PVC pipe is clamped by two traction devices, starts motor, motor drives conveyer belt to move right, conveyer belt band Dynamic two traction devices move right, so that PVC pipe be driven to move right；By the rubber block on two traction devices by pvc pipe Material clamps, and can be close to the outer surface of PVC pipe and the surface of rubber block by the deformation of rubber block, so as to will PVC pipe clamps, and avoids making PVC pipe loosen and can not persistently move right with traction device in the process of moving；Cylinder Starting drives inclined plate 28 to be moved left and right, and sets inclined-plane for the front end face of inclined plate, and the rear end face of sliding block 26 is set as inclined-plane, To which when conveyer belt is mobile to make sliding block 26 be in contact with inclined plate 28, inclined plate 28 is moved forward with movable slider 26, sliding block 26 is driven Rack gear 25 moves forward, so as to the distance between adjusting slider 26 and fixed plate 35.

Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment should fall within the scope of the present invention.
