Description

Technical Field

[0001] This utility model provides a modified polyamide material preparation device, belonging to the technical field of modified polyamide material production equipment, and particularly relates to a mixing cylinder for the preparation of modified polyamide materials. Background Technology

[0002] Polyamides, due to their high strength, good wear resistance, and excellent chemical corrosion resistance, have been widely used in many fields such as automobiles, electronics, and machinery. However, as various industries continue to raise the requirements for material performance, ordinary polyamide materials are no longer able to meet practical needs in certain specific properties. Therefore, modification of polyamides has become an important direction in current research and production.

[0003] In the preparation of modified polyamide materials, polyamide is generally first pre-mixed with other polymers and additives, and then melted. Pre-mixing can be done at room temperature by stirring to ensure the components are roughly evenly dispersed. Then comes the melting stage, and finally, the product is formed through molding processes such as injection molding and extrusion. When mixing polyamide with other polymers, a mixing drum with a stirring structure is typically used, where polyamide and other polymers are poured into the mixing drum sequentially for mixing. When mixing with polyethylene, which has a similar particle size to polyamide, both polyamide and polyethylene can be added simultaneously. However, whether added sequentially or simultaneously, the polyamide and polyethylene particles are relatively concentrated before reaching the bottom of the mixing drum, resulting in poor dispersion. Mixing relies almost entirely on the stirring structure after they completely fall into the mixing drum. Furthermore, the solid granular polyamide and polyethylene have poor flowability, and complete mixing using a stirring structure takes a long time. To address these issues, a modified polyamide material preparation device is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that relying solely on the stirring structure within the mixing drum to completely mix materials such as polyamide and polyethylene requires a considerable amount of time.

[0005] To address the aforementioned problems, the proposed technical solution is as follows: a modified polyamide material preparation apparatus, comprising a mixing cylinder with an end cap; a heating block is provided on the inner wall of the mixing cylinder, a discharge hole is provided at the bottom of the mixing cylinder, and a stirring assembly is provided inside the mixing cylinder; further comprising:

[0006] The system comprises a lower dispersing cone and an upper dispersing cone. The lower dispersing cone is located inside the mixing cylinder and is fixedly connected to the stirring assembly. The upper dispersing cone is located directly above the lower dispersing cone and is connected to the lower dispersing cone via a vertical sliding assembly. The end cap is provided with a first feed pipe and a second feed pipe corresponding to the inclined surface of the upper dispersing cone, and the lower dispersing cone has several dispersing holes.

[0007] The lower unblocking rod and the upper unblocking rod are fixedly connected to the top of the lower dispersing cone and correspond to the discharge hole of the upper dispersing cone; the upper unblocking rod is fixedly connected to the bottom of the upper dispersing cone and corresponds to the position of the dispersing hole.

[0008] As an improvement, the stirring assembly includes a rotating motor, a rotating shaft, and stirring blades. The rotating motor is located at the bottom of the mixing cylinder, the rotating shaft is located inside the mixing cylinder, and the rotating shaft is fixedly connected to the output shaft of the rotating motor; the stirring blades are fixedly connected to the rotating shaft.

[0009] As an improvement, the lower dispersing cone is fixedly connected to the rotating shaft, and the dispersing holes are evenly distributed on the lower dispersing cone.

[0010] As an improvement, there is a gap between the lower unblocking rod and the discharge hole of the upper dispersing cone; the number of upper unblocking rods and dispersing holes are the same, and there is a gap between the upper unblocking rods and the dispersing holes.

[0011] As an improvement, the vertical sliding assembly includes a fixed cylinder and a sliding rod. The fixed cylinder is fixedly connected to the lower dispersing cone block, and the sliding rod is fixedly connected to the lower part of the upper dispersing cone cylinder, and the sliding rod is slidably disposed relative to the fixed cylinder. The sliding rod is fixedly connected to the fixed cylinder by screws.

[0012] As an improvement, the mixing cylinder is provided with a slot, and a locking block fixedly connected to the bottom of the end cap is inserted into the slot.

[0013] The beneficial effects of this utility model are:

[0014] 1. The lower dispersing cone is located inside the mixing drum and is fixedly connected to the stirring assembly; the upper dispersing cone is located directly above the lower dispersing cone, and the end cap is provided with a first feed pipe and a second feed pipe corresponding to the inclined surface of the upper dispersing cone; by setting the upper dispersing cone and the lower dispersing cone, the raw materials can be pre-dispersed as they fall to the bottom of the mixing drum, which greatly reduces the time required for the raw materials to be completely mixed at the bottom of the mixing drum; and the upper dispersing cone and the lower dispersing cone are fixedly connected to the stirring assembly, and the power provided by the stirring assembly drives the upper dispersing cone and the lower dispersing cone to rotate, thereby increasing the dispersion effect.

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

[0024] according to Figure 1-5 As shown: This utility model provides a modified polyamide material preparation device, including a mixing cylinder 1, an end cap 2 on the mixing cylinder 1; a slot 12 is opened on the mixing cylinder 1, and a locking block 11 fixedly connected to the bottom of the end cap 2 is inserted into the slot 12 to increase the sealing of the connection between the end cap 2 and the mixing cylinder 1; a heating block 9 is provided on the inner wall of the mixing cylinder 1, a discharge hole 5 is provided at the bottom of the mixing cylinder 1, and a stirring assembly is provided inside the mixing cylinder 1;

[0025] like Figure 3 As shown, the stirring assembly includes a rotary motor 7, a rotating shaft 6, and stirring blades 8. The rotary motor 7 is located at the bottom of the mixing cylinder 1, the rotating shaft 6 is located inside the mixing cylinder 1, and the rotating shaft 6 is fixedly connected to the output shaft of the rotary motor 7; the stirring blades 8 are fixedly connected to the rotating shaft 6.

[0026] like Figure 3 , 4 As shown, the lower dispersing cone 13 is located inside the mixing cylinder 1 and is fixedly connected to the rotating shaft 6; the upper dispersing cone 10 is located directly above the lower dispersing cone 13, and the upper dispersing cone 10 and the lower dispersing cone 13 are connected by a vertical sliding assembly; the vertical sliding assembly includes a fixed cylinder 18 and a sliding rod 20, the fixed cylinder 18 is fixedly connected to the lower dispersing cone 13, the sliding rod 20 is fixedly connected to the lower part of the upper dispersing cone 10, and the sliding rod 20 is slidably disposed relative to the fixed cylinder 18; the sliding rod 20 is fixedly connected to the fixed cylinder 18 by screws 19, which facilitates disassembly.

[0027] like Figure 3 , 4 As shown, the end cap 2 is provided with a first feed pipe 3 and a second feed pipe 4 corresponding to the inclined surface of the upper dispersing cone 10, and the lower dispersing cone 13 is provided with a number of evenly distributed dispersing holes 14. The raw materials falling onto the lower dispersing cone 13 can be evenly dispersed at the bottom of the mixing cylinder 1 through the dispersing holes 14.

[0028] The lower unblocking rod 16 is fixedly connected to the top of the lower dispersing cone 13, and corresponds to the discharge hole 17 of the upper dispersing cone 10; the upper unblocking rod 15 is fixedly connected to the bottom of the upper dispersing cone 10, and corresponds to the position of the dispersing hole 14. By setting the lower unblocking rod 16 and the upper unblocking rod 15, and utilizing the relative sliding of the upper dispersing cone 10 and the lower dispersing cone 13, the lower unblocking rod 16 can be inserted into the discharge hole 17, and the upper unblocking rod 15 can be inserted into the dispersing hole 14. When the dispersing hole 14 or the discharge hole 17 is blocked, it can be easily cleared. There is a gap between the lower unblocking rod 16 and the discharge hole 17 of the upper dispersing cone 10; the number of upper unblocking rods 15 and the number of dispersing holes 14 are the same, and there is a gap between the upper unblocking rod 15 and the dispersing hole 14, which ensures that the upper and lower unblocking rods do not obstruct the flow of raw materials.

[0029] The principle of this utility model

[0030] like Figure 3As shown, polyamide granules and polyethylene granules are simultaneously added to the mixing cylinder 1 through the first feed pipe 3 and the second feed pipe 4. The rotating motor 7 is started, causing the rotating shaft 6 and the stirring blades 8 to rotate. Simultaneously, the rotating shaft 6 drives the lower dispersing cone 13 and the upper dispersing cone 10 to rotate. The raw materials added from the first feed pipe 3 and the second feed pipe 4 enter the inclined surface inside the upper dispersing cone 10. As the upper dispersing cone 10 rotates, the raw materials move within it. When the raw materials reach the discharge hole 17 at the bottom of the upper dispersing cone 10, preliminary mixing occurs. The preliminarily mixed raw materials fall from the discharge hole 17 onto the inclined surface of the lower dispersing cone 13 and move along it. The rotating lower dispersing cone 13 increases the mobility of the raw materials. The material enters the bottom of the mixing cylinder 1 through the dispersing hole 14 of the lower dispersing cone 13. At this point, the raw materials that have completely fallen to the bottom of the mixing cylinder 1 have already undergone two mixing processes. When the stirring blades 8 are used to completely mix them, the required time can be greatly shortened. After complete mixing, activate heating block 9 to melt the mixed material.

[0031] This application also facilitates the cleaning of the dispersion hole 14, such as Figure 4 , 5 As shown, when the dispersion hole 14 is blocked, first open the end cover 2, remove the screw 19, and let the sliding rod 20 slide relative to the fixed cylinder 18. At this time, the upper dispersion cone 10 slides relative to the lower dispersion cone 13, and all the upper unblocking rods 15 are inserted into the dispersion hole 14, which can clean all the dispersion holes 14 at the same time, with high unblocking efficiency. When the upper dispersion cone 10 slides relative to the lower dispersion cone 13, the lower unblocking rod 16 can also be inserted into the discharge hole 17, thereby unblocking the discharge hole 17.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
