[0002] Plastic granules are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. They are generally obtained through a series of process treatments such as recycling, cleaning, crushing, melting, extrusion and pelletizing of waste plastics. The shape of plastic granules is relatively uniform, usually in regular granular shape, relatively uniform in size, easy to process, and can be made into various plastic products. During the production process, there are strict requirements on the purity, particle size distribution, melt index and other indicators of plastic granules. As an important raw material for plastic products, the demand for plastic granules is constantly growing, and the production equipment of plastic granules is also constantly developing and improving.

[0036] Reference Figure 4-Figure 5The limiting mechanism includes a card block 8, and a transverse notch is provided on the outer wall of the card block 8 to meet the transverse movement of the adjustment block 9. The card block 8 is slidably connected to the inner wall of the U-shaped block 3.

The top of the card block 8 is elastically connected to the U-shaped block 3 through a reset spring 10. When the adjustment block 9 slides upward with the card block 8, the reset spring 10 is stretched. When resetting, the elastic force of the reset spring 10 is used to move the card block 8 downward. The right end outer wall of the card block 8 is slidably connected with the adjusting block 9, the card block 8 is inserted into the inner wall of the square groove 7, the left end outer wall of the mold 12 is in contact with the right end outer wall of the discharge port 2, and the mold 12 is provided with a row of circular holes of regular size and shape to meet the requirements of plastic being squeezed out from the discharge port 2.

[0038] Working principle: First, when the mold 12 needs to be replaced, first slide the adjusting block 9 upward along the vertical opening of the L-shaped groove 11. When the adjusting block 9 slides upward, the card block 8 also moves upward. At this time, the reset spring 10 is in a compressed state. When the card block 8 moves out of the inner wall of the square groove 7 and returns to the inner wall of the U-shaped block 3, move the adjusting block 9 along the horizontal opening of the L-shaped groove 11 so that the card block 8 stays on the inner wall of the U-shaped block 3. Rotate the hinge rod 5 counterclockwise to drive the sliding block 6 to move out of the U-shaped block 3, and then move the mold 12 out of the U-shaped block 3. After replacing the new mold 12, rotate the hinge rod 5 clockwise to drive the sliding block 6 back to the original position. Figure 2 When the position is shown in the figure, the adjusting block 9 is then moved horizontally to the vertical opening of the L-shaped groove 11, and the reverse elastic force of the return spring 10 is used to make the clamping block 8 clamped on the inner wall of the square groove 7, and the replacement of the mold 12 is completed.

[0039] When it is necessary to adjust the size of the diameter of the screen 16 on the inner wall of the feed port 13, manually twist the threaded rod 14. While the threaded rod 14 rotates, it drives the ring 15 to move outward. The movement of the ring 15 drives the adjustment net 17 to move outward. At this time, the diameter of the screen 16 at the entrance can be reduced. When the diameter of the screen 16 needs to be increased, just twist the threaded rod 14 in the opposite direction according to the above operation.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
