[0024] Embodiment

[0025] Please refer to Figures 1-4 As shown, the present utility model provides a technical solution: a grinding machine for PVC pipe production;

[0026] A secondary crushing box 3 is fixedly installed at the upper end of the grinding machine body 1, an installation box 7 is fixedly installed at the right end of the secondary crushing box 3, a first motor 4 is fixedly installed at the right end of the installation box 7, a gear set 5 is fixedly installed on the output shaft of the first motor 4, a crushing roller 6 is fixedly installed at the left end of the gear set 5, the crushing roller 6 is rotatably installed at the inner end of the secondary crushing box 3, and the crushing roller 6 is arranged above the grinding machine body 1. The gear set 5 is rotatably installed inside the installation box 7, and the gear set 5 is arranged in two groups inside the installation box 7. A feeding box 14 is fixedly installed at the left end of the feeding pipe 2, which is convenient for uniformly crushing the material twice and then grinding it, improving the efficiency of crushing and grinding;

[0027] A screw conveyor blade 8 rotates inside the feeding pipe 2, a fixed box 9 is fixedly installed at the outer end of the feeding pipe 2, a micro motor 10 is fixedly installed at the right end of the fixed box 9, and a magnet column 11 is fixedly installed on the output shaft of the micro motor 10.

[0028] The magnet column 11 is rotatably installed at the inner end of the fixed box 9, and a cover plate 13 is snap-fitted at the upper end of the fixed box 9. A scraper 12 is fixedly installed at the inner end of the fixed box 9, and the rear end of the scraper 12 is attached to the outer surface of the magnet column 11, which is convenient for removing iron products such as iron nails in the material and improving the purity of PVC pipe grinding.

[0029] Specific working principle:

[0030] As Figure 1 . Figure 2 . Figure 3 And Figure 4As shown, when using the grinding machine for producing PVC pipes, the crushed PVC pipe residues are stored inside the feeding box 14. When grinding, the motor drives the spiral conveying blade 8 to rotate, and conveys the residues into the grinding body 1 through the feeding pipe 2. When the residues pass through the fixed box 9, the micro-motor 10 drives the magnet column 11 to rotate inside the fixed box 9. The magnet column 11 adsorbs iron products or iron nails in the residues, and the adsorbed impurities are scraped off by the scraper 12. The cover plate 13 can be opened regularly to clean the impurities inside the fixed box 9. Before entering the grinding body 1, the residues first enter the secondary crushing box 3. The first motor 4 drives the gear set 5 inside the installation box 7 to rotate. When the gear set 5 rotates, it meshes with another gear set 5, driving the two crushing rollers 6 to rotate inward. The crushing rollers 6 perform secondary crushing on the falling PVC pipe residues, making the residues broken into smaller and more evenly sized debris, and then falling into the grinding body 1 for grinding. The above completes a series of operations of the grinding machine for producing PVC pipes. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
