Technical realization elements:

6. Technical problems solved

7. Aiming at the above-mentioned shortcomings in the prior art, the present utility model provides a pvc pellet production and cutting device, which can effectively solve the problem that the prior art rotating blades and fixed blades are located outside the end of the conveyor belt of the strip conveyor. Therefore, the solid pvc is cut in a suspended state, which will easily cause insufficient cutting, that is, the problem of not being completely cut into granular pvc.

8. Technical solution

9. In order to achieve the above objectives, the present utility model is achieved through the following technical solutions:

10. A pvc pellet production and cutting device, including a machine body, a cutting roller and a supporting roller that rotate symmetrically on the machine body, a driver that drives the supporting roller to rotate, and two sets of drives fixed on the machine body and symmetrically at both ends of the cutting roller and The step wheel near the supporting roller, the cutting roller and the supporting roller rotate synchronously with opposite directions, and there is a gap between the cutting roller and the supporting roller for the passage of solid strip PVC, and the width of the gap is not greater than that of the solid The diameter of the strip PVC, the circumferential side wall of the cutting roller is provided with knife grooves at equal angles, and the cutting knife is slidably connected in the knife groove. Both ends of the cutting knife are provided with elastic components for resetting and buffering. Both ends of the cutting knife Rotating connected with rollers;

11. Wherein, when the rollers at both ends of a set of cutting knives are in contact with the corresponding step wheels respectively, the cutting knives extend from the knife groove and cut the solid strip-shaped pvc located in the gap.

12. Further, both ends of the cutting roller are fixedly installed with an inner ring and an outer ring that are coaxial with them. The outer side wall of the inner ring circumference is provided with guide rods corresponding to the knife groove at an equal angle, and the outer ring faces the end of the cutting roller. Equivalently angled on one side of the part is provided with the guide rod

The cross-section is an L-shaped groove, and the end of the guide rod away from the inner ring is embedded in the corresponding groove. Both ends of the cutting knife are fixedly connected with sliding sleeves that slide through the guide rod. The roller Are respectively connected to the sliding sleeve in rotation, the elastic component includes two sets of springs, and the two sets of springs are respectively sleeved on the guide rods located on both sides of the sliding sleeve;

13. By setting the L-shaped groove, when the inner ring is fixed and installed, and then the outer ring is fixedly installed, the end of the guide rod away from the inner ring is embedded in the groove, thereby improving the guide rod between the inner ring and the outer ring. stability;

14. Through the cooperation of the guide rod and the sliding sleeve, the cutting knife can slide in the knife groove;

15. By setting springs on the guide rods on both sides of the sliding sleeve, not only the buffering and resetting of the cutting knife is realized, but also the elastic action of the spring on the cutting knife can effectively prevent the cutting knife from protruding out of the knife slot due to centrifugal force;

16. After the inner ring is coaxially fixed and installed on the end of the cutting roller by bolts and other fixing parts, then one set of springs of the elastic component are respectively sleeved on the guide rod, and then the cutting knife is installed into the knife groove. The sliding sleeves at both ends of the cutting knife are respectively sleeved on the guide rod, and then another set of springs of the elastic component are sleeved on the guide rod, so that the two sets of springs of the elastic component are symmetrically located on both sides of the sliding sleeve, and the outer ring is fixed respectively It is installed at the end of the cutting roller, and the ends of each group of guide rods are respectively embedded in the grooves to realize the installation of the cutting knife, so as to facilitate the subsequent replacement of the cutting knife.

17. Further, the circumferential side wall of the supporting roller is provided with several sets of knife edge grooves at equal angles;

18. Through the blade groove, the blade of the cutting knife can extend into the blade groove, thereby effectively avoiding damage to the blade of the cutting knife and increasing the service life of the cutting knife.

19. Further, it also includes a fixed concave frame fixedly connected to the upper side of the body, a movable concave frame slidably connected in the fixed concave frame, and a screw screw connected to the upper side of the movable concave frame and threaded through the fixed concave frame. The cutting roller is rotatably connected in the movable concave frame through a rotating shaft, the supporting roller is rotatably connected in the fixed concave frame through a shaft rod, and the step wheels are all fixedly connected to the fixed concave frame through a mounting frame;

20. By rotating the handle on the top of the screw, the cutting roller can be moved up and down. During the initial cutting, the cutting roller is moved upward to increase the gap, and then the solid strip PVC is passed through the cutting roller and the supporting roller. Then move the cutting roller down to reset, so as to facilitate the solid strip pvc through the cutting roller and the supporting roller.

21. Further, the ends of the rotating shaft and the shaft are provided with gears that mesh with each other;

22. Through meshing gears, the cutting roller and the supporting roller can rotate synchronously and rotate in opposite directions.

23. Further, the side walls of the two sets of gears are provided with alignment markings;

24. By setting the alignment marks on the side walls of the two sets of gears, it is convenient to match the knife groove of the cutting roller with the knife edge groove of the supporting roller.

25. Beneficial effects

26. Compared with the known public technology, the technical solution provided by the utility model has the following beneficial effects:

27. The utility model not only drives the solid strip-shaped pvc to continuously pass between the cutting roller and the supporting roller through the synchronous and oppositely rotating cutting roller and the supporting roller, but also makes the solid state in the gap between the cutting roller and the supporting roller. The strip-shaped PVC is cut and supported, so as to effectively avoid the solid strip-shaped PVC being in a suspended state during cutting, so that the cutting knife of the cutting roller can continuously cut the solid strip-shaped PVC, effectively avoiding insufficient cutting.
