Description

Technical Field

[0001] This application relates to the field of extruder technology, and in particular to a high-efficiency mixing screw. Background Technology

[0002] Plastic extruders are used to plasticize and mold plastics. The extruder heats the raw material, turning the solid material into a uniform viscous fluid. Under the action of the extrusion mechanism, the molten material is continuously extruded from the die head at a certain pressure and speed to form the desired plastic part. During operation, the raw material and auxiliary materials are first added to the barrel in proportion. The rotation of the screw inside the barrel and the heating of the barrel cause the mixture to become a molten polymer. Then, the rotation of the screw drives the plastic forward, causing the material to be ejected from the nozzle at high pressure and speed.

[0003] Existing extruder screws require cleaning after use to prevent residue from hardening, but disassembling the screws is inconvenient, leading to reduced work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problem that existing extruder screws require cleaning after use to prevent hardened residues, but are inconvenient to disassemble, leading to reduced work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency mixing screw includes a barrel and a high-efficiency screw. An operating box is fixedly connected to one end of the barrel. The operating box is provided with an installation component for installing the high-efficiency screw and a disassembly component for ejecting the high-efficiency screw. The installation component includes a U-shaped frame disposed within the operating box. The high-efficiency screw is located within the barrel and one end penetrates through the side wall of one end of the barrel and is fixedly connected to a square column. The square column is located within the U-shaped frame. A plurality of connecting bolts are provided on one side wall of the U-shaped frame. The output end of the connecting bolts penetrates through the U-shaped frame and the square column and is threadedly connected to a nut.

[0007] The disassembly assembly includes through slots at the top and bottom of the operation box. Each through slot is provided with a limiting rod. One end of the limiting rod is threaded to one side wall of the through slot, and the other end of the limiting rod passes through the other side wall of the through slot. The operation box is provided with a push plate. Both ends of the push plate are respectively disposed in the through slots. Both ends of the side wall of the push plate are provided with insertion holes that are adapted to the limiting rods. A cylinder for pushing the push plate is fixedly connected to one end of the operation box away from the cylinder.

[0008] By adopting the above technical solution, during use, the nut is removed by rotating it, and then the connecting bolt is pulled out to disengage the U-shaped frame from the square column. The push plate is then placed into the operating box, positioned between the U-shaped frame and the square column. The limit rods are then threaded through the insertion holes and connected to the side walls of the through slots to secure them and stabilize the push plate. The cylinder is then activated to push the push plate, which in turn pushes the square column, pushing the high-efficiency screw out of the cylinder. This facilitates removal by the operator and minimizes the inconvenience of disassembling the screw, thus reducing work efficiency.

[0009] Optionally, the mounting assembly is provided in two sets, and an auxiliary screw is provided inside the cylinder. The auxiliary screw is located below the high-efficiency screw and is arranged parallel to it. One end of the auxiliary screw passes through one side wall of the cylinder and is connected to the other set of mounting assemblies.

[0010] By adopting the above technical solutions, the shearing and mixing effect on materials can be enhanced by using an auxiliary screw.

[0011] Optionally, two drive motors are installed inside the operation box, and the output ends of the drive motors are respectively fixedly connected to one end of the U-shaped frame.

[0012] By adopting the above technical solutions, the U-shaped frame can be rotated by the drive motor, which in turn drives the high-efficiency screw and the auxiliary screw to rotate, pushing the plastic forward and mixing the material.

[0013] Optionally, a resistance heating wire is wound around the inner wall of the cylinder.

[0014] By adopting the above technical solutions, the cylinder can be heated by resistance heating wire, generating high temperatures inside the cylinder to melt the material.

[0015] Optionally, a feeding pipe that communicates with the interior of the cylinder is fixedly connected to one side of the top end of the cylinder, and the feeding pipe is trumpet-shaped.

[0016] By adopting the above technical solutions, the material can be easily fed into the cylinder through the trumpet-shaped feeding pipe, so that the high-efficiency screw can push, shear and melt the material.

[0017] Optionally, the cylinder output end is fixedly connected to multiple positioning rods, and the push plate has a positioning groove on the side wall near the cylinder, the cylinder output end is located in the positioning groove and the positioning rods pass through the push plate.

[0018] By adopting the above technical solution, when the cylinder pushes the push plate, the cylinder output end is located in the positioning groove, and the positioning rod passes through the push plate, which can improve the stability of the cylinder when pushing the push plate.

[0019] Optionally, a cooling water pipe is wound around the inner wall of the cylinder below the resistance heating wire, with both ends of the cooling water pipe extending to the outside of the cylinder.

[0020] By adopting the above technical solutions, cooling water is added to the cooling water pipes to achieve cooling water circulation, which can remove excess heat generated during heating, regulate the material temperature, and ensure the stability and efficiency of the mixing process.

[0021] Optionally, both side walls of the operation box are hinged with mesh plates.

[0022] By adopting the above technical solutions, the connecting bolts and nuts can be easily disassembled by opening the mesh panel.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] 1. This application utilizes the cooperative arrangement of structures such as a U-shaped frame, a push plate, and a cylinder. During use, the nut is removed by rotating it, and the connecting bolt is pulled out, disengaging the U-shaped frame from the square column. The push plate is then placed into the operating box, positioned between the U-shaped frame and the square column. Limiting rods are then threaded through the insertion holes and connected to the side walls of the through slots to secure the limiting rods and stabilize the push plate. The cylinder is then activated to push the push plate, which in turn pushes the square column, extending the high-efficiency screw from the cylinder. This facilitates removal by the operator and minimizes the inconvenience of disassembling the screw, thus reducing work efficiency.

[0025] 2. The cylinder can be heated by resistance heating wire, which generates high temperature inside the cylinder to melt the material. At the same time, cooling water is added to the cooling water pipe to achieve cooling water circulation, which can remove the excess heat generated during heating, regulate the material temperature, and ensure the stability and efficiency of the mixing process.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] Please see Figure 1-3 A high-efficiency mixing screw includes a barrel 1 and a high-efficiency screw 2. An operation box 3 is fixedly connected to one end of the barrel 1. The operation box 3 is provided with an installation component for installing the high-efficiency screw 2 and a disassembly component for ejecting the high-efficiency screw 2. The installation component includes a U-shaped frame 4, a square column 5, a connecting bolt 6, and a nut 7.

[0033] The U-shaped frame 4 is set inside the operation box 3. The high-efficiency screw 2 is located inside the cylinder 1 and one end passes through the side wall of one end of the cylinder 1 and is fixedly connected to the square column 5. The square column 5 is located inside the U-shaped frame 4. Multiple connecting bolts 6 are set and located on one side wall of the U-shaped frame 4. The output ends of the connecting bolts 6 all pass through the U-shaped frame 4 and the square column 5 and are threadedly connected to the nuts 7 respectively.

[0034] The disassembly assembly includes a through groove 8, a limiting rod 9, a push plate 10, an insertion hole 11, and a cylinder 12;

[0035] Two through slots 8 are respectively opened at the upper and lower ends of the operation box 3. Two limiting rods 9 are respectively located in the through slots 8. One end of the limiting rod 9 is threaded to one side wall of the through slot 8, and the other end of the limiting rod 9 passes through the other side wall of the through slot 8. The push plate 10 is set in the operation box 3 with both ends located in the through slot 8. Two insertion holes 11 are respectively opened at both ends of the side wall of the push plate 10. By passing the limiting rods 9 through the insertion holes 11 and threading them to one side wall of the through slot 8, the push plate 10 can be installed to prevent the push plate 10 from falling off. At the same time, when the high-efficiency screw 2 is running, the push plate 10 can be removed to prevent it from affecting the operation of the high-efficiency screw 2. The cylinder 12 is fixedly connected to the end of the operation box 3 away from the cylinder 1, and the output end passes through the operation box 3 and is close to the side wall of the push plate 10.

[0036] In use, nut 7 is removed by rotating it, and then connecting bolt 6 is pulled out to disengage the U-shaped frame 4 from the square column 5. Then, push plate 10 is placed into operation box 3, so that push plate 10 is positioned between U-shaped frame 4 and square column 5. Then, limit rod 9 is threaded through insertion hole 11 and connected to the side wall of through groove 8 to fix limit rod 9 and keep push plate 10 stable. Then, cylinder 12 is activated to push push plate 10, which pushes square column 5 to push high-efficiency screw 2 out of cylinder 1, making it easy for operators to remove and minimizing the problem of inconvenience in screw disassembly, which would reduce work efficiency.

[0037] Reference Figure 1 The installation components are set in two sets. An auxiliary screw 13 is provided inside the cylinder 1. The auxiliary screw 13 is located below the high-efficiency screw 2 and is set in parallel. One end of the auxiliary screw 13 passes through one side wall of the cylinder 1 and is connected to the other set of installation components. The auxiliary screw 13 can enhance the shearing and mixing effect of the material and prevent the material from failing to be fully mixed and melted in the feed tube.

[0038] Reference Figure 1 The operation box 3 is equipped with two drive motors 14. The output ends of the drive motors 14 are fixedly connected to one end of the U-shaped frame 4. The drive motors 14 can make the U-shaped frame 4 rotate, which drives the high-efficiency screw 2 and the auxiliary screw 13 to rotate, pushing the plastic forward and mixing the material.

[0039] Reference Figure 1 The inner wall of the cylinder 1 is wound with a resistance heating wire 15, which can heat the cylinder 1 and generate high temperature inside the cylinder 1 to melt the material.

[0040] Reference Figure 1 A feeding pipe 16, which is connected to the inside of the cylinder 1, is fixedly connected to one side of the top end of the cylinder 1. The feeding pipe 16 is funnel-shaped, which facilitates the feeding of materials into the cylinder 1, so that the high-efficiency screw 2 can push, shear and melt the materials.

[0041] Reference Figure 4 The output end of the cylinder 12 is fixedly connected to multiple positioning rods 17. The side wall of the push plate 10 near the cylinder 12 is provided with a positioning groove 18. The output end of the cylinder 12 is located in the positioning groove 18 and the positioning rods 17 pass through the push plate 10. When the cylinder 12 pushes the push plate 10, the output end of the cylinder 12 is located in the positioning groove 18 and the positioning rods 17 pass through the push plate 10, which can improve the stability of the cylinder 12 when pushing the push plate 10.

[0042] Reference Figure 1A cooling water pipe 19 is wound around the inner wall of the cylinder 1 below the resistance heating wire 15. Both ends of the cooling water pipe 19 extend to the outside of the cylinder 1. By connecting one end of the cooling water pipe 19 to a water supply device and the other end to a collection device, the water supply device adds cooling water to the cooling water pipe 19, so that the cooling water circulates in the cooling water pipe 19. This can remove the excess heat generated when the cylinder 1 is heated, regulate the material temperature, and ensure the stability and efficiency of the mixing process.

[0043] Reference Figure 3 Both sides of the operation box 3 are hinged with mesh plates 20, which can be opened to facilitate the disassembly of the connecting bolts 6 and nuts 7.

[0044] The implementation principle of this application is as follows: During use, the user first disengages one end of the limiting rod 9 from one side wall of the through groove 8 by rotating the limiting rod 9. Then, the push plate 10 is removed, causing the drive motor 14 to drive the high-efficiency screw 2 and auxiliary screw 13 to rotate. Simultaneously, material is added into the cylinder 1 through the feeding pipe 16, causing the high-efficiency screw 2 and auxiliary screw 13 to push and shear the material. The cylinder 1 is then heated by the resistance heating wire 15, generating high temperatures inside the cylinder 1 to melt the material. Simultaneously, cooling water is added to the cooling water pipe 19 to achieve cooling water circulation, which removes excess heat generated during heating, regulates the material temperature, and ensures the stability and efficiency of the mixing process. When further high-efficiency... When disassembling and cleaning the screw 2 and auxiliary screw 13, open the mesh plate 20, rotate the nut 7 to remove it, then pull out the connecting bolt 6 to disengage the U-shaped frame 4 from the square column 5. Then, place the push plate 10 into the operation box 3, positioning it between the U-shaped frame 4 and the square column 5. Next, thread the limiting rod 9 through the insertion hole 11 and connect it to the side wall of the through groove 8 to fix the limiting rod 9 and keep the push plate 10 stable. Then, start the cylinder 12 to push the push plate 10, which in turn pushes the square column 5, pushing the high-efficiency screw 2 out of the cylinder 1. This makes it easier for the operator to remove the screw and minimizes the inconvenience of disassembling it, which could reduce work efficiency.
