Description

Technical Field

[0001] This utility model belongs to the field of extrusion equipment technology, and in particular relates to an integrated extrusion and mixing equipment for modified plastics. Background Technology

[0002] In plastics processing, it is also known as extrusion molding or extrusion; in rubber processing, it is known as extrusion. It refers to a processing method in which materials are heated and plasticized by the action between the extruder barrel and screw, and are continuously pushed forward by the screw through the die head to form products or semi-finished products of various cross-sections.

[0003] In existing technologies, modified plastics require the addition of different types of raw materials during extrusion mixing. These raw materials need to be thoroughly mixed before entering the extruder for processing. However, current methods often involve weighing multiple raw materials sequentially and pouring them into a mixing tank. This results in the aggregation of similar raw materials, leading to prolonged mixing time, poor mixing effect, increased overall production time, and reduced quality. Therefore, we provide a dedicated integrated extrusion mixing equipment for modified plastics to solve the aforementioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model is an integrated extrusion and mixing equipment for modified plastics, including a base 1, an extrusion tank 5, and a mounting box 12. The extrusion tank 5 is located above the base 1, and the mounting box 12 is located above the extrusion tank 5. Two fourth support plates 11 are fixedly connected to the upper end of the base 1, and the mounting box 12 is fixedly connected to the upper end of the two fourth support plates 11. A mixing tank 13 is fixedly installed inside the mounting box 12. A cover plate is provided at the upper end of the mixing tank 13, and two feed ports are opened on the upper end of the cover plate. Each feed port is fixedly connected to a feed hopper 15, and the two feed hoppers 15 are connected to the inside of the mixing tank 13. A second servo motor 14 is fixedly installed on the upper end of the mixing tank 13. The output shaft of the second servo motor 14 passes through the inner wall of the mounting box 12 and is fixedly connected to the drive shaft 28. Multiple main helical gears 16 and a transmission cylinder 29 are fixedly sleeved on the drive shaft 28. The multiple main helical gears 16 are meshed with two driven helical gears 17. The center of the multiple driven helical gears 17 in the transmission cylinder 29 is fixedly connected to the blade shaft 30. The end of the multiple blade shafts 30 away from the driven helical gears 17 passes through the transmission cylinder 29 and is fixedly connected to the stirring blade 20. The upper end face of the base 1 is fixedly connected to the water tank 24. The upper end face of the water tank 24 is fixedly connected to the spray plate 25. The upper end face of the base 1 is fixedly connected to the water pump 22. The upper end face of the base 1 is fixedly connected to the collection box 27.

[0028] Specifically: Raw materials are fed into the feed hopper 15, and then the second servo motor 14 is started so that its output shaft drives the drive shaft 28 to rotate. The rotation of the drive shaft 28 will cause multiple main helical gears 16 to drive the secondary helical gears 17 on both sides to rotate, thereby causing multiple blade shafts 30 to rotate in the inner wall of the transmission cylinder 29 and drive the stirring blades 20 to rotate, thereby achieving the stirring of the raw materials in the mixing tank 13. At the same time, the raw materials are stirred thoroughly during feeding and stirring to prevent the same raw materials from agglomerating, which would lead to a longer stirring time, poor stirring effect, longer overall production time, and reduced quality.

[0029] Example 2

[0030] Please see Figure 1-6 Based on Embodiment 1, a bottom frame 34 is provided on the lower end face of the cover plate. Two shafts 31 are fixedly connected to the center of the helical gears 17 within the bottom frame 34. Two unblocking plates 19 are provided in the two feed hoppers 15. Threaded holes are provided on the side walls of the two unblocking plates 19. Two shafts 33 are threaded into the two threaded holes. Couplings 32 are provided between the two shafts 31 and the two shafts 33. A first support plate 2 is fixedly connected to the upper end face of the base 1. A first servo motor 3 is fixedly connected to the left side face of the first support plate 2. A spiral rod 21 is installed through the left side face of the first support plate 2 at the output end of the first servo motor 3. A second support plate 4 is fixedly connected to the upper end face of the base 1. An extrusion tank 5 is fixedly connected inside the second support plate 4. The output end of the first servo motor 3 is rotatably connected inside the extrusion tank 5 and passes through the extrusion tank. The extrusion tank 5 has a discharge hole 9 on its right side wall; a third support plate 7 is fixedly connected to the upper end of the base 1, and a heating sleeve 8 is fixedly connected inside the third support plate 7. The inner ring of the heating sleeve 8 is fitted onto the surface of the extrusion tank 5; a cutting rod 10 is rotatably connected to the right side of the extrusion tank 5; a feed pipe 6 is fixedly connected to the surface of the extrusion tank 5; the extrusion tank 5 and the mixing tank 13 are connected through the feed pipe 6; the water inlet of the water pump 22 passes through the front of the water tank 24 and is connected; a transport pipe 23 is installed at the water outlet of the water pump 22; one end of the transport pipe 23 is connected to the inside of the spray plate 25; a filter inclined plate 26 is fixedly connected inside the water tank 24; the right side of the water tank 24 overlaps with the upper end of the collection box 27; gravity sensor displays are fixedly installed on both sides of the mounting box 12, and the gravity sensor displays are electrically connected to the two unblocking plates 19 respectively.

[0031] Specifically: Weight changes are monitored by a gravity sensor display to control precise feeding. Under the rotation of the drive shaft 28, the meshing of the main helical gear 16 and two driven helical gears 17 in the bottom frame 34 causes the two first shafts 31 to rotate. The rotation of the two first shafts 31 will drive the two second shafts 33 to rotate through the coupling 32, thereby causing the two unblocking plates 19 to rotate in the feed hopper 15 and unblock it. The screw rod 21 unblocks the extrusion tank 5, improves the extrusion effect, prevents blockage, accurately dispenses materials, mixes evenly, shortens the mixing time, enhances the mixing effect, and improves work efficiency. The water pump 22 delivers water from the water tank 24 to the spray plate 25, which can spray and cool the high-temperature plastic, allowing the plastic to cool down quickly, reducing the time required for natural cooling, and improving the production efficiency of this device.

[0032] The working principle of this utility model is as follows: The operator puts the raw material into the feeding hopper 15. The amount of raw material can be accurately measured through the gravity sensor display. Then, the second servo motor 14 is started, causing its output shaft to drive the drive shaft 28 to rotate. This causes multiple main helical gears 16 to drive the secondary helical gears 17 on both sides to rotate, which in turn drives the stirring blades 20 to rotate, thus stirring the raw material in the mixing tank 13. Simultaneously, the material is thoroughly stirred during both feeding and stirring. Then, it falls into the extrusion tank 5 through the feeding pipe 6. The operator then opens the heating sleeve 8 to heat the plastic in the extrusion tank 5. The plastic is melted, and then the operator starts the first servo motor 3 to drive the screw rod 21 to rotate clockwise. This pushes the melted plastic to the right and squeezes it out of the discharge hole 9. At the same time, the cutting rod 10 rotates to cut the plastic squeezed out of the discharge hole 9 into small pieces, which then fall onto the filter inclined plate 26. At this time, the operator starts the water pump 22 to transport the water in the water tank 24 through the transport pipe 23 to the area below the spray plate 25 to spray and cool the plastic. Then the plastic particles slide down the filter inclined plate 26 into the collection box 27, and the water flows into the water tank 24 through the filter inclined plate 26 for reuse.
