Abstract
Description
Technical Field
[0001] This utility model relates to the field of extruder technology, specifically to an extrusion device for an extruder. Background Technology
[0002] Additives play a crucial role in extruder operation. They increase melt flowability, improve melt stability, and reduce melt viscosity, thereby enhancing processing efficiency and product quality. Additives and plastic raw materials are typically mixed together and stored in a feed barrel before entering the die. Currently, the mixing ratio of additives and plastic raw materials is fixed. Different additive ratios can produce products with varying properties. When producing products with different properties, the additives and plastic raw materials need to be remixed and then stored in the feed barrel, which is cumbersome. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0027] In the embodiments, such as Figure 1 , Figure 2 As shown, an extrusion device for an extruder includes a barrel 1, and further includes:
[0028] Connecting seat 2 is located at the feed inlet of barrel 1;
[0029] The first material feeding channel 3 is located inside the connecting seat 2;
[0030] The second material discharge channel 4 is located inside the connecting seat 2 and is connected to the first material discharge channel 3;
[0031] The No. 1 material cylinder 5 is set on the connecting seat 2 and connected to the No. 1 material discharge channel 3;
[0032] The No. 2 material cylinder 6 is set on the connecting seat 2 and connected to the No. 2 material discharge channel 4;
[0033] Baffles 7 are respectively installed at the discharge ports of material cylinder 5 and material cylinder 6;
[0034] The power element 8 is mounted on the connecting seat 2 and is used to drive the baffle plate 7 to move horizontally.
[0035] The power element 8 is a cylinder. The plastic raw material can be stored in the first material cylinder 5, and the additives are stored in the second material cylinder 6. When mixing is required, the size of the discharge port of the second material cylinder 6 can be controlled by the position of the baffle plate 7 driven by the power element 8, thereby changing the ratio of plastic raw material and additives to produce products with different properties. The mixing ratio can be flexibly adjusted and it has good versatility.
[0036] In the embodiments, such as Figure 1 , Figure 2 As shown, an exhaust channel 9 is provided at the connection between the first material discharge channel 3 and the second material discharge channel 4, and an exhaust port 10 for communicating with the exhaust channel 9 is provided on the top of the connecting seat 2. During the mixing and plasticizing process, some gas can be discharged from the exhaust port 10 through the feed port of the barrel 1 to ensure product quality.
[0037] In the embodiments, such as Figure 3 As shown, an observation window 11 is provided at the exhaust channel 9. The observation window 11 can be used to check whether there is any blockage, so that it can be dealt with in a timely manner.
[0038] In the embodiments, such as Figure 4 As shown, the inner wall of the feed inlet of the barrel 1 is evenly distributed with grooves 12. This increases the friction between the mixing material and the feed inlet of the barrel 1, preventing slippage between the mixing material and the screw, which could lead to blockage of the feed inlet of the barrel 1.
[0039] In the embodiments, such as Figure 1 As shown, a sleeve 13 is provided at the feed inlet of the barrel 1, and a cooling groove 14 is provided between the sleeve 13 and the outer wall of the barrel 1. The cooling groove 14 is a spiral groove, which is used to cool the feed inlet of the barrel 1 to prevent the mixed material from softening due to increased friction and sticking to the screw surface, thus causing unstable screw feeding.
[0040] In the embodiments, such as Figure 1 , Figure 4 As shown, the inner wall of the barrel 1 is provided with a wear-resistant layer 15. The wear-resistant layer 15 is used to reduce the wear on the inner wall of the barrel 1 and extend the service life of the barrel 1.
[0041] In the embodiments, such as Figure 1As shown, the barrel 1 is provided with several temperature measuring holes 16. Temperature sensors are installed in the temperature measuring holes 16 to facilitate timely monitoring and adjustment of the internal temperature of the barrel 1.
[0042] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
