[0001] This utility model relates to the field of cross-linked insulation material production technology, and in particular to a mixing device for cross-linked insulation material production. Background Technology

[0002] Cross-linked insulation materials are generally used in cables and are an essential component in cable production. To ensure the protective effect of cross-linked insulation materials on cables, a mixing device is needed during the production process to mix various raw materials with different functions to obtain the required mixture.

[0003] A search revealed Chinese patent CN217594388U, which discloses a mixing device for producing cross-linked insulation material under ultraviolet light irradiation. The aforementioned patent uses a scraper structure to achieve the function of stirring raw materials and preventing sedimentation. However, since the scraper is located at the bottom of the rotating shaft, it cannot lift the raw materials that have settled to the bottom, resulting in poor uniformity of material stirring. Therefore, in order to advance the industry's technology, better realize the mixing function of cross-linked insulation material, and improve the core technology competitiveness, this application proposes a new implementation scheme that differs from the structure and application method of the mixing device in the prior art. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the use of existing mixing devices, the scraper is located at the bottom of the rotating shaft and cannot lift the raw materials that have sunk to the bottom, resulting in poor uniformity of the raw materials. Therefore, this invention proposes a mixing device for the production of cross-linked insulating materials.

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

[0006] A mixing device for producing cross-linked insulation material includes a front vertical plate, a rear vertical plate, and a stirring assembly. Two electric push rods are fixedly connected to one side of the rear vertical plate, and the output ends of the two electric push rods are fixedly connected to the same connecting plate.

[0007] The mixing assembly includes a main shell and a secondary shell, which are combined to form a mixing shell. A main rotating column is fixedly connected to one outer wall of the main shell, and one end of the main rotating column is rotatably inserted into one side of the front vertical plate. A second motor is fixedly connected to one side of the front vertical plate. Gears are fixedly connected to the output end of the second motor and one end of the main rotating column, and the two gears mesh with each other. A secondary rotating column is fixedly connected to one outer wall of the secondary shell, and the secondary rotating column is rotatably inserted into one side of the connecting plate. A mixing frame is rotatably inserted into one end of the secondary rotating column. A first motor is fixedly connected to one side of the connecting plate, and the output end of the first motor is connected to one end of the mixing frame. A feed inlet is provided at the top of the outer surface of the main shell, and an upper control valve is fixedly connected to the top of the main shell, and the upper control valve communicates with the main shell through the feed inlet.

[0008] Furthermore, the bottom ends of the front vertical plate and the rear vertical plate are fixedly connected to the same collection box, and the upper surface of the collection box is fixedly connected to a guide hopper, and the guide hopper is vertically aligned with the position of the mixing assembly.

[0009] Furthermore, two support seats are fixedly connected to the upper surface of the collection box, and the main shell is rotatably connected to the inner surface of the support seats through bearings.

[0010] Furthermore, multiple guide rods are fixedly inserted into one side of the rear vertical plate, and all the guide rods are slidably inserted into one side of the connecting plate.

[0011] Furthermore, a feed pipe is fixedly connected to the top of the upper control valve, and the feed pipe is located directly above the feed hopper.

[0012] Furthermore, sealing gaskets are respectively snapped onto the opposite sides of the main shell and the sub-shell, and the sealing gasket on the main shell is in contact with the sealing gasket on the sub-shell.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The design of the mixing shell and the stirring frame, which are composed of the main shell and the auxiliary shell in the mixing assembly, can rotate independently, which can ensure the uniform mixing of cross-linked insulation material in the mixing shell. The rotation of the stirring frame can stir the raw materials in the mixing shell, and the rotation of the mixing shell can drive the raw materials in it to rotate at the same time, thereby avoiding the precipitation of raw materials in the mixing shell during the stirring process and ensuring the uniform mixing of cross-linked insulation material.

[0018] 3. The design of the guide hopper can guide the cross-linked insulation material discharged from the feed pipe into the collection box after the mixing component completes the mixing of the cross-linked insulation material. The guide baffle in the collection box can concentrate and guide the cross-linked insulation material in the collection box, which facilitates the discharge of the cross-linked insulation material in the collection box.

[0019] 4. The design with sealing gaskets in both the main shell and the sub-shell can seal the connection between the main shell and the sub-shell, preventing the cross-linked insulation material inside the mixed shell from falling off during the mixing process. The combination of positioning rod and positioning hole can strengthen the docking of the main shell and the sub-shell, while ensuring the synchronicity of the rotation of the main shell and the sub-shell.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Referring to Figures 1-6, a cross-linked insulation material production mixing device includes a front vertical plate 1, a rear vertical plate 2, and a stirring assembly 3. Two electric push rods 4 are fixed to one side of the rear vertical plate 2 by bolts, and the output ends of the two electric push rods 4 are fixed to the same connecting plate 5 by bolts.

[0029] The mixing assembly 3 includes a main shell 301 and a secondary shell 303, which are combined to form a mixing shell. A main rotating column 302 is fixedly inserted into one side of the outer wall of the main shell 301, and one end of the main rotating column 302 is rotatably inserted into one side of the front vertical plate 1. A second motor 7 is fixed to one side of the front vertical plate 1 by bolts. The output end of the second motor 7 and one end of the main rotating column 302 are both keyed to gears 8, and the two gears 8 mesh with each other. A secondary rotating column 304 is fixedly inserted into one side of the outer wall of the secondary shell 303, and the secondary rotating column 304 is rotatably inserted into one side of the connecting plate 5. A mixing frame 305 is rotatably inserted into one end of the secondary rotating column 304. A first motor 6 is fixed to one side of the connecting plate 5 by bolts, and the output end of the first motor 6 is connected to one end of the mixing frame 305. The mixing assembly 3 consists of the main shell 301 and the secondary shell 303. The design of the mixing shell and the stirring rack 305, which can rotate independently, ensures the uniform mixing of the cross-linked insulation material in the mixing shell. The rotation of the stirring rack 305 can stir the raw materials in the mixing shell, and the rotation of the mixing shell can drive the raw materials in it to rotate at the same time, thereby avoiding the precipitation of the raw materials in the mixing shell during the stirring process and ensuring the uniform mixing of the cross-linked insulation material. A material inlet is provided at the top of the outer surface of the main shell 301. The top of the main shell 301 is fixed with an upper control valve 306 by bolts, and the upper control valve 306 is connected to the main shell 301 through the material inlet. The design of the main shell 301 and the secondary shell 303 in the stirring assembly 3 can be separated and opened to facilitate the cleaning of the stirring assembly 3. After the main shell 301 and the secondary shell 303 are separated, the stirring rack 305 is exposed to the outside, which is convenient for operators to clean the entire stirring assembly 3.

[0030] The bottom ends of the front vertical plate 1 and the rear vertical plate 2 are fixed to the same collection box 12 by bolts. A guide hopper 16 is fixedly inserted into the upper surface of the collection box 12, and the guide hopper 16 is aligned vertically with the mixing assembly 3. Through the design of the guide hopper 16, the cross-linked insulation material discharged from the feed pipe 10 into the collection box 12 can be guided after the mixing assembly 3 has completed the mixing of the cross-linked insulation material. The bottom of the inner wall of the collection box 12 is fixed with a guide inclined plate 17 by bolts, and the output end of the collection box 12 is fixed with a lower control valve 18 by bolts. The guide inclined plate 17 in the collection box 12 can centrally guide the cross-linked insulation material in the collection box 12, which facilitates the discharge of the cross-linked insulation material in the collection box 12.

[0031] The upper surface of the collection box 12 is fixed with two support seats 9 by bolts, and the main shell 301 is rotatably connected to the inner surface of the support seats 9 by bearings. Multiple guide rods 11 are fixedly inserted into one side of the rear vertical plate 2, and the multiple guide rods 11 are slidably inserted into one side of the connecting plate 5. The top of the upper control valve 306 is fixed with a material passage pipe 10 by bolts, and the material passage pipe 10 is located directly above the guide hopper 16.

[0032] Meanwhile, sealing gaskets 13 are respectively snapped onto the opposite sides of the main shell 301 and the secondary shell 303, and the sealing gaskets 13 on the main shell 301 and the secondary shell 303 are in contact. Through the design that both the main shell 301 and the secondary shell 303 have sealing gaskets 13, the connection between the main shell 301 and the secondary shell 303 can be sealed to prevent the cross-linked insulating material in the mixed shell from falling off during the mixing process. Multiple positioning rods 14 are fixedly inserted into one side of the main shell 301, and multiple positioning holes 15 are provided on one side of the secondary shell 303. The positioning rods 14 are slidably inserted into the corresponding positioning holes 15. The combination of positioning rods 14 and positioning holes 15 can strengthen the docking of the main shell 301 and the secondary shell 303, and at the same time ensure the synchronicity of the rotation of the main shell 301 and the secondary shell 303.

[0033] The working principle of this embodiment is as follows: In use, the operator first puts various cross-linked insulation materials into the mixing shell composed of the main shell 301 and the secondary shell 303 through the feed pipe 10. Then, the upper control valve 306 is closed. The operator then starts the first motor 6 and the second motor 7 respectively. When the first motor 6 rotates, it drives the stirring frame 305 to rotate, and the stirring frame 305 stirs and mixes the raw materials in the mixing shell. When the second motor 7 rotates, it drives the mixing shell and the raw materials in it to rotate through the gear 8, so as to avoid the raw materials in the mixing shell from settling. After the stirring assembly 3 has mixed the cross-linked insulation materials well, the feed pipe 10 on the main shell 301 is rotated to the bottom of the main shell 301 through the second motor 7. At this time, the feed pipe 10 is aligned with the guide hopper 16. The operator opens the upper control valve 306, and the mixed cross-linked insulation materials in the mixing shell enter the collection box 12 through the feed pipe 10 and the guide hopper 16. In this way, the mixing of the cross-linked insulation materials by the mixing device is completed.

[0034] As shown in Figure 6, when it is necessary to clean the mixing assembly 3, the operator can activate the electric push rod 4. The electric push rod 4 retracts, causing the connecting plate 5 and its auxiliary rotating column 304, auxiliary shell 303 and mixing frame 305 to slide towards the electric push rod 4, so that the main shell 301 and auxiliary shell 303 are separated, and the mixing frame 305 is exposed to the outside. At this time, the operator can clean the mixing assembly 3 with cleaning tools. In this way, the opening operation for cleaning the mixing assembly 3 in the mixing device is completed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
