Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic elastomer production, especially to a pipeline water cooling conveying device of high flow elastomer. BACKGROUND
[0002] In the production process of plastic particles, the plastic is heated and melted by the extruder and then cut into particles. At present, there are two ways to convey the cut particles, one is underwater cutting, and the other is water tank cutting. The applicant previously applied for an underwater cutting machine with a publication number of CN116021666A. This underwater cutting machine performs the cutting process underwater, and the cut material directly flows out with the water flow.
[0003] Then, when producing some high flow elastomers, the material flowability is strong, so the extrusion force of the extruder screw on the material is not uniform when the material passes through the die head of the extruder. Because the material flowability is strong, the material accumulation at the lower part of the die head will be more compact than that at the upper part of the die head. Therefore, the extrusion force of the material at the lower part of the die head will be greater than that at the upper part of the die head when the extruder is extruded. As a result, there will be some differences in the extrusion amount and speed of the material extruded from the die head. Because the rotating speed of the cutting tool of the extruder is consistent when cutting, the cut particles will have different lengths due to the difference in extrusion speed between the upper and lower extrusion holes of the die head, resulting in uneven particles. SUMMARY

[0024] like Figure 2 and Figure 3 As shown, the guiding and conveying device includes a conveying frame 9, on which a lower guide roller 10 is rotatably mounted. The lower guide roller 10 is provided with a plurality of guide ring grooves 11, which correspond to the position of the discharge port 8. The guide ring grooves 11 allow the elastomer strip to be inserted, ensuring stable and accurate conveying of the elastomer strip.

In this way, the elastomer strip can pass between the upper guide roller 14 and the lower guide roller 10. The conveying is more stable and accurate due to the constraint of the upper guide roller 14 and the lower guide roller 10. When the number of elastomer strips extruded by the die head is too large, some of the elastomer strips can pass through the upper guide roller 14, ensuring conveying efficiency and improving conveying flexibility.
[0026] In this embodiment, the upper roller frame 13 is mounted on the gantry frame 12 via a vertical lifting adjustment mechanism; by adjusting the height of the upper roller frame 13, the distance between the upper guide roller 14 and the lower guide roller 10 is adjusted to accommodate elastic strips of different sizes, ensuring stable and accurate conveying when conveying between the upper guide roller 14 and the lower guide roller 10.

[0029] The working principle of the embodiment is as follows: the water-cooled cutting die head 5 of the extruder extrudes the elastomer strip, water is fed into the water inlet 6, the elastomer strip is cooled in the upstream horizontal pipe section 2, and then bent into the vertical pipe section 3, and finally into the downstream horizontal pipe section 4, and finally conveyed out from the discharge port 8; the number of the extruded elastomer strips is sequentially arranged, placed on the guide ring groove 11 corresponding to the lower guide roller 10, and then the screw lifting machine 15 drives the upper guide roller 14 to descend and cooperates with the lower guide roller 10 to convey; when the number of the elastomer strips exceeds the number of the guide ring grooves 11 of the lower guide roller 10, the elastomer strips pass above the guide ring grooves 11 of the upper guide roller 14 and the lower guide roller 10, respectively.
