Description

Technical Field

[0001] This utility model relates to the field of plastic extruder technology, and specifically to a plastic extruder. Background Technology

[0002] Plastic extruders are used to plasticize and mold plastics. The extruder heats the raw material to turn the solid material into a uniform viscous fluid, and under the action of the extrusion mechanism of the extruder, the molten material is continuously extruded from the die head at a certain pressure and speed to become the desired plastic part.

[0003] Existing plastic extruders are usually equipped with a feeding hopper on top. Because the feeding hopper is quite high, each time the plastic extruder is loaded, the staff needs to carry the raw material and climb up the ladder to the top before pouring the material into the feeding hopper. This not only consumes physical strength and increases the workload of the staff, but also poses a risk of injury to the staff when climbing the ladder. Utility Model Content

[0023] like Figure 1-4 As shown, a plastic extruder includes an extruder body 1. The top of the extruder body 1 is connected to an inclined feed pipe 2, which facilitates the raw material in the feed pipe 2 to slide into the extruder body 1. The end of the feed pipe 2 away from the extruder body 1 is connected to a discharge box 3. The side of the discharge box 3 is provided with a discharge port that is connected to the feed port of the feed pipe 2. The bottom of the discharge box 3 is an inclined structure that is connected to the feed port of the feed pipe 2, which facilitates the raw material in the discharge box 3 to slide into the feed pipe 2 from the discharge port.

[0024] A door 4 is provided at the discharge port to block the discharge port; an opening mechanism is provided on the discharge box 3, which includes a first motor 5 and a first screw 6. Slide grooves 10 are provided on the upper part of the inner walls on opposite sides of the discharge box 3. A limiting rod 11 is provided on the side of the door 4 to slide in cooperation with the slide grooves 10, limiting the door 4 so that the door 4 slides vertically and vertically with the discharge box 3; a first support base 7 is fixedly connected to the outer wall of the discharge box 3, and a first slider 8 is fixedly connected to the door 4. The first slider 8 has a first threaded hole 9. One end of the first screw 6 is rotatably connected to the first support base 7, and the other end is threadedly connected to the first threaded hole 9. The first motor 5 is fixed on the top of the feeding box 3. One end of the first screw 6 passes through the first support base 7 and is fixedly connected to the output end of the first motor 5. The first motor 5 drives the first screw 6 to rotate, thereby driving the first slider 8 to rise or fall, so that the door 4 opens or closes. The top of the feeding box 3 is provided with a cover 12 to prevent impurities from falling into the feeding box 3 and avoid contaminating the raw materials.

[0025] A lifting mechanism is provided on the ground, comprising a base 13, a second motor 14, and a second screw 15. The base 13 is fixed to the ground, and a support rod 16 is fixedly connected to the top of the base 13. Two opposing second support seats 17 are fixedly connected to one side of the support rod 16. The second screw 15 is rotatably connected between the two second support seats 17. A reducer 22 is installed on the top of the base 13. One end of the second screw 15 passes through the second support seat 17 and is fixedly connected to the output end of the reducer 22. The output end of the second motor 14 is fixedly connected to the input end of the reducer 22. A second slider 18 is fixedly connected to the side of the feeding box 3. The base 18 is provided with a second threaded hole 19 that is threadedly connected to the second screw 15. A slide rod 20 is fixedly connected between the two second support seats 17. The second slider 18 is provided with a slide hole 21 that is slidably engaged with the slide rod 20. Through the sliding engagement between the second slider 18 and the slide rod 20, the second slider 18 can be limited, so that the feeding box 3 is slidably connected between the two second support seats 17. The second motor 14 drives the second screw 15 to rotate through the reducer 22, thereby driving the second slider 18 to rise or fall, so that the feeding box 3 can be raised or lowered. A recessed platform 23 for placing the feeding box 3 is fixedly connected to the side of the base 13.

[0026] It also includes a controller, which controls the first motor 5 and the second motor 14 to work.

[0027] Working principle:

[0028] like Figure 1-4 As shown, when the plastic extruder is working, the feeding box 3 will be placed on the recessed platform 23. First, open the cover 12 and pour the raw material into the feeding box 3. After the raw material is poured in, put the cover 12 back on the top of the feeding box 3 to prevent impurities from falling into the feeding box 3 and avoid contaminating the raw material.

[0029] Then, the controller starts the second motor 14, which drives the second screw 15 to rotate via the reducer 22, thereby causing the second slider 18 to rise, raising the discharge box 3 until it reaches the height corresponding to the feed inlet of the feed pipe. The controller then stops the second motor 14, at which point the discharge port of the discharge box 3 connects with the feed inlet of the feed pipe 2. After that, the controller starts the first motor 5, which drives the first screw 6 to rotate, thereby causing the first slider 8 to rise, opening the door 4. The raw material in the discharge box 3 slides from the discharge port into the feed pipe 2, and then slides from the feed pipe 2 into the extruder body 1. Once all the raw material has fallen into the extruder body 1, the loading is complete. This eliminates the need for workers to carry the raw material and climb ladders to a high place for loading, reducing the physical exertion and workload of workers, and avoiding the risk of workers falling and getting injured while climbing stairs.
