Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to the feed barrel of an extruder. Background Technology

[0002] The production principle of a plastic extruder is as follows: plastic raw material enters the barrel through the feed cylinder, then the solid plastic is melted by heating and rotating the screw. The melted plastic is then extruded through a die, and finally cooled and solidified to obtain the desired plastic product. Plastic raw materials absorb moisture at room temperature, leading to dampness. Slippage occurs when the screw comes into contact with the damp plastic, causing the plastic to accumulate at the feed inlet and cause blockage. Therefore, the plastic raw material needs to be dried before entering the feed cylinder. However, drying and conveying the plastic requires additional time, which undoubtedly extends the production cycle and reduces production efficiency. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] In the embodiments, such as Figure 1 , Figure 2 As shown, the extruder's feed barrel includes a barrel body 1, and also includes:

[0025] Hollow shaft 2 is rotatably mounted on cylinder 1;

[0026] The first heat-conducting rod 3 is set on the hollow shaft 2. The first heat-conducting rod 3 is a hollow rod and is connected to the hollow shaft 2.

[0027] The second heat-conducting rod 4 is vertically set on the first heat-conducting rod 4;

[0028] Heating element 5 is installed inside heat-conducting rod 3;

[0029] Mounting base 6 is located on top of hollow shaft 2 and is used to connect to heating tube 5;

[0030] Motor 7 is located on the top surface of cylinder 1;

[0031] The transmission assembly 8 is located between the hollow shaft 2 and the motor 7.

[0032] The transmission component 8 is a gear set. The motor drives the hollow shaft 2 to rotate through the gear set. The first heat-conducting rod 3 and the second heat-conducting rod 4 act on the plastic raw material to heat and dry it. An air inlet can be opened on the bottom side of the cylinder 1. The hot air is discharged from the feed hole of the cylinder 1, so that the drying and cylinder feeding are completed at one time, further improving production efficiency.

[0033] In the embodiments, such as Figure 1 , Figure 2 As shown, the second heat-conducting rod 4 is positioned at both the upper and lower ends of the first heat-conducting rod 3, and the upper and lower heat-conducting rods 4 are arranged in a staggered manner. This allows for uniform heating of the plastic raw material, resulting in good drying performance.

[0034] In the embodiments, such as Figure 1 , Figure 2 As shown, the second heat-conducting rod 4 is a hollow rod and is connected to the first heat-conducting rod 3. The second heat-conducting rod 4 has vent holes 9 around its circumference. Hot air can flow out from the vent holes 9 and act on the plastic raw material, improving the drying efficiency of the plastic raw material.

[0035] In this embodiment, both the first heat-conducting rod 3 and the second heat-conducting rod 4 are made of aluminum alloy. Aluminum alloy has good thermal conductivity, high strength, good corrosion resistance, and a long service life.

[0036] In the embodiments, such as Figure 1 As shown, the cylinder 1 is equipped with a temperature sensor 10 and a display panel 11 for connecting to the temperature sensor 10. The display panel 11 allows the temperature inside the cylinder 1 to be monitored and adjusted in a timely manner to prevent the plastic material from softening due to excessive temperature, which would make it inconvenient to transport.

[0037] In the embodiments, such as Figure 1 As shown, an auxiliary material cylinder 12 is provided on one side of the cylinder 1, and a screw conveyor 13 is provided between the auxiliary material cylinder 12 and the cylinder 1. The auxiliary material cylinder 12 is used to hold additives, which are convenient to be mixed with plastic raw materials and enter the cylinder.

[0038] 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.
