(3) Advantageous effects

In order to solve the problems that in the prior art, local cracks and damage can be generated in the use process of a PVC pipe, pipes with different sizes are required to be cut and repaired aiming at the pipes with different sizes, the loss of the new pipe caused by cutting the new pipe to repair the old pipe is increased, and the new pipes with different sizes are cut aiming at the cracks and the damaged parts of the pipes with different sizes, so that the defect of inconvenience in repair is overcome;

when the pipe diameters of the existing standard pipelines are similar, the thicknesses of the pipe walls are also similar, and although the inner arc surfaces of the repair sheets close to the damaged pipelines are similar to the outer surface radians of the damaged pipelines and have higher fitting degrees, the damage resistance of the repair sheets is actually similar to that of the damaged pipelines due to the similar pipe wall thicknesses, and under the condition that the pipelines are damaged, the repair sheets with the similar damage resistance are insufficient and cannot bear the responsibility of protecting the damaged areas; when the pipeline piece with larger pipe diameter and larger thickness is selected, although the damage resistance is stronger than that of the damaged pipeline, the difference between the curvature of the inner cambered surface of the pipeline piece and the curvature of the outer surface of the damaged pipeline is larger, the two cannot be completely attached, and the repairing effect is poor; therefore, the existing standard pipeline is used for repairing, only one of the fitting degree and the damage resistance strength can be selected, and the two can not be used;

designing a double-clamping and limiting system, extruding and smoothing the system and a concave pasting arc system, manually taking up a feeding appliance, then opening the double-clamping and limiting system, adding a PVC raw material into the double-clamping and limiting system by using the feeding appliance, then closing the double-clamping and limiting system, then controlling the extruding and smoothing system to extrude the PVC raw material in the double-clamping and limiting system to enable the PVC raw material to be preliminarily molded into a plate shape, not solidifying the PVC raw material at the moment, taking down a molding part in the double-clamping and limiting system after extruding and smoothing, fixing the molding part into the concave pasting arc system, further carrying out shaping and bending on the preliminarily molded plate-shaped pipe repairing piece by the concave pasting arc system according to a mold with a required size again, cooling and solidifying the molding part to obtain a required PVC pipe repairing piece, wherein the size of the PVC pipe repairing piece is larger than the cracking seam of the PVC pipe, and then manually spraying an adhesive on the surface around the crack of the cracked PVC pipe, then, adhering the obtained PVC pipe repairing piece to the surface of the crack, and further completing the repair of the PVC critical crack;

(IV), the restoration of PVC pipe fitting damage fracture to various sizes has been realized, use corresponding not unidimensional mould to the pipe fitting of unidimensional not and stereotype, and then extrusion obtains the PVC tubular product restoration piece that accords with not unidimensional pipe fitting, the loss of cutting new pipe fitting and restoreing the new pipe fitting that old pipe fitting brought has been saved, and can directly carry out prosthetic effect to the pipe fitting crack of unidimensional and damaged part, and make PVC tubular product restoration piece laminate with the pipeline surface of damage completely, the loss resistance intensity of restoreing the pipe fitting has been guaranteed simultaneously.

Firstly, measuring the size to be repaired, respectively fixedly inserting two ends of a standard mould pipe column 6020 conforming to the corresponding size into an installation chuck 6017, then controlling a corresponding electric push rod 6018 to extend, further inserting a corresponding electric push rod 6018 into a hole of an inner hole 6019, further fixing two ends of the standard mould pipe column 6020, then controlling a first electric telescopic lifting rod 6014 and a second electric telescopic lifting rod 6016 to contract, further driving an installation top frame 6015, the installation chuck 6017, the electric push rod 6018, the inner hole 6019 and the standard mould pipe column 6020 to move downwards, at the moment, a first soft plate mould 406 and a second soft plate mould which are internally provided with pressed PVC materials are placed at the top of the first forming roller column 6011 and the second forming roller column 6013, then downwards moving the standard mould pipe column 6020 to press a first soft plate mould 409 and a second soft plate mould 409 at the top of the first forming roller 6011 and the second forming roller column 6013, at this time, the standard mold pipe column 6020 presses down the middle parts of the first soft plate mold 406 and the second soft plate mold 409, and then the first molding roller column 6011 and the second molding roller column 6013 move to both sides until the PVC material inside the first soft plate mold 406 and the second soft plate mold 409 is bent and molded to meet the use standard.

Example 5

On the basis of the embodiment 4, as shown in fig. 13, a grinding repair system 7 is further included, the grinding repair system 7 is installed at the right front part of the lower deck 2, and the grinding repair system 7 includes a sliding side frame 701, a waste collecting box 702, a handle 703, a protective outer frame 704, a fourth rotating shaft 705 and a grinding wheel 706; four sliding side frames 701 are welded at the right side of the bottom of the lower-layer machine bed plate 2; the four sliding side frames 701 are slidably connected with a waste collecting box 702; a handle 703 is welded at the middle part of the front side of the waste collection box 702; the right side of the top of the lower bedplate 2 is connected with a protective outer frame 704 through a bolt; a fourth rotating shaft 705 is rotatably connected to the right side of the protective outer frame 704; a grinding wheel 706 is fixedly connected to the left end of the fourth rotating shaft rod 705; the right end of the fourth rotating shaft 705 is fixed to the first rotating shaft 502.

After the PVC pipe repair piece is formed, controlling to realize the rotation of a fourth rotating shaft rod 705, driving a polishing wheel 706 to rotate by the fourth rotating shaft rod 705, manually enabling the edge of the PVC pipe repair piece to be close to the polishing wheel 706, and further polishing and finishing the irregular position of the edge of the PVC pipe repair piece by the polishing wheel 706 to obtain a regular shape and a flat edge; after a standard PVC pipe repairing piece is obtained, the size of the PVC pipe repairing piece is larger than the cracking seam of the PVC pipe, then the adhesive is manually sprayed to the surface around the crack of the cracked PVC pipe, and then the obtained PVC pipe repairing piece is adhered to the surface of the crack, so that the crack of the PVC key pipe is repaired.

The above examples are merely representative of preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, various changes, modifications and substitutions can be made without departing from the spirit of the present invention, and these are all within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
