Description

Technical Field

[0001] This utility model relates to the technical field of cross-linked polyethylene foaming equipment, and in particular to a multi-station alternating cross-linked polyethylene foaming equipment. Background Technology

[0002] Cross-linked polyethylene (XLPE) is widely used in power cable insulation, building insulation materials, and automotive interior cushioning components due to its excellent electrical insulation, chemical corrosion resistance, and high flexibility. With the continuous growth in demand for XLPE products across various industries, production efficiency and product quality have become increasingly important industry focuses. Foaming, as a core step in XLPE production, directly determines the performance and quality of the product.

[0003] For current foaming equipment, the existing foaming plastic uniform foaming device disclosed in patent number "CN206383380U" controls a rotary motor to rotate clockwise, driving a stirring rod to alternately stir clockwise and counterclockwise, thus fully agitating the resin emulsion. It also features a first and second disc to ensure uniform feeding of the resin emulsion, allowing it to fully contact and incorporate air. While this stirring device can drive the stirring rod to rotate clockwise and counterclockwise alternately, the relatively fixed position of the stirring rod within the tank limits the effective stirring area. In actual stirring, the emulsion near the stirring rod receives sufficient shearing and mixing because it is directly within the stirring range. However, the emulsion at the edge of the foaming reaction tank, being far from the direct action range of the stirring rod, experiences significantly reduced stirring force and frequency, making it difficult to achieve sufficient agitation and dispersion.

[0004] Accordingly, this application proposes a multi-station alternating cross-linked polyethylene foaming device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-station alternating cross-linked polyethylene foaming device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-station alternating cross-linked polyethylene foaming equipment includes a base, a turntable on the base, connecting frames symmetrically fixedly connected to the turntable, a foaming reaction tank fixedly connected to the end of each connecting frame away from the turntable, and a base frame fixedly connected to the top surface of the base.

[0008] Also includes:

[0009] A drive assembly for driving the turntable to rotate;

[0010] A stirring assembly is used to uniformly stir the cross-linked polyethylene in the foaming reaction tank.

[0011] Preferably, a hydraulic rod is fixedly connected to the inner side wall of the base frame, and a reaction cap is fixedly connected to the output end of the hydraulic rod.

[0012] Preferably, the driving component includes:

[0013] The first motor is fixedly connected to the bottom surface of the base;

[0014] A rotating shaft is fixedly connected to the output end of the first motor, and the rotating shaft is fixedly connected to the turntable.

[0015] Preferably, the stirring assembly includes:

[0016] The second motor is fixedly connected to the bottom of the foaming reaction tank;

[0017] A stirring rod, which is fixedly connected to the output end of a second motor;

[0018] A triangular convex disc, which is fixedly connected to the stirring rod;

[0019] A rotating shaft is rotatably connected to the triangle of a triangular cam.

[0020] The first gear is fixedly connected to the rotating shaft.

[0021] Preferably, the stirring assembly further includes:

[0022] The second gear is fixedly connected to the inner wall of the foaming reaction tank;

[0023] A crank, which is hinged to a rotating shaft;

[0024] A stirring blade, which is hinged to the end of the crank away from the axis of rotation.

[0025] Preferably, there are three rotating shafts and first gears, and the rotating shafts and first gears are arranged in a ring on the side wall of the second gear, with the second gear meshing with the first gear.

[0026] This utility model has the following beneficial effects:

[0027] 1. By setting up a stirring assembly, the stirring blades move in a circular motion along the stirring rod in the foaming reaction tank, which allows for uniform stirring of the cross-linked polyethylene far from the stirring rod, effectively ensuring foaming quality and improving the product qualification rate.

[0028] 2. By setting up a drive component, multi-station alternating operation can be realized. While one foaming reaction tank is foaming, another foaming reaction tank can be loaded or unloaded at the same time, which significantly improves the foaming production efficiency of cross-linked polyethylene. At the same time, the reaction cover is controlled by an electric push rod, which makes it convenient for workers to load or unload materials. Attached Figure Description

[0034] 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.

[0035] Reference Figures 1 to 4 A multi-station alternating cross-linked polyethylene foaming equipment includes a base 1, a turntable 2 on the base 1, connecting frames 3 symmetrically fixedly connected to the turntable 2, and foaming reaction tanks 4 fixedly connected to the ends of the connecting frames 3 away from the turntable 2. A base frame 5 is fixedly connected to the top surface of the base 1, and a hydraulic rod 51 is fixedly connected to the inner wall of the base frame 5. A reaction cover 52 is fixedly connected to the output end of the hydraulic rod 51. The internal space dimension of the base frame 5 is larger than the circumference diameter of the rotation trajectory of the foaming reaction tank 4, ensuring that when the foaming reaction tank 4 rotates circumferentially under the drive of the turntable 2, a safe distance is always maintained between its outer wall and the inner wall of the base frame 5, thus avoiding collisions or friction between the foaming reaction tank 4 and the base frame 5 during equipment operation.

[0036] A multi-station alternating cross-linked polyethylene foaming equipment also includes a drive assembly and a stirring assembly, wherein the drive assembly is used to drive the turntable 2 to rotate.

[0037] The drive assembly includes a first motor 21 and a rotating shaft 22. The first motor 21 is fixedly connected to the bottom surface of the base 1, and the rotating shaft 22 is fixedly connected to the output end of the first motor 21. The rotating shaft 22 is fixedly connected to the turntable 2.

[0038] The stirring assembly is used to uniformly stir the cross-linked polyethylene inside the foaming reaction tank 4. The stirring assembly includes a second motor 41, a stirring rod 42, a triangular cam 43, a rotating shaft 44, a first gear 45, a second gear 46, a crank 47, and a stirring blade 48. The second motor 41 is fixedly connected to the bottom end of the foaming reaction tank 4, the stirring rod 42 is fixedly connected to the output end of the second motor 41, the triangular cam 43 is fixedly connected to the stirring rod 42, and the rotating shaft 44 is rotatably connected to the triangle of the triangular cam 43. By setting the triangular cam 43, it has strong stability and evenly transmits the driving force of the stirring rod 42 to the three legs, so that the force of the entire stirring assembly is distributed on the three support points.

[0039] The first gear 45 is fixedly connected to the rotating shaft 44, the second gear 46 is fixedly connected to the inner wall of the foaming reaction tank 4, the crank 47 is hinged to the rotating shaft 44, and the stirring blade 48 is hinged to the end of the crank 47 away from the rotating shaft 44. The center distance between the stirring blade 48 and the stirring rod 42 is greater than the length of the crank 47. This design ensures that when the stirring blade 48 reciprocates under the drive of the crank 47, its trajectory boundary is always far away from the surface of the stirring rod 42, thus avoiding mechanical interference between the two in complex stirring actions.

[0040] There are three rotating shafts 44 and first gears 45. The rotating shafts 44 and first gears 45 are arranged in a ring on the side wall of the second gear 46, and the second gear 46 meshes with the first gear 45.

[0041] In this utility model, when using this device, the first motor 21 is started to drive the rotating shaft 22 to rotate, and the external turntable 2 rotates accordingly, so that one of the foaming reaction tanks 4 is located below the base frame 5. At this time, the hydraulic rod 51 extends and drives the reaction cover 52 to cover the foaming reaction tank 4 to carry out the foaming operation; the other foaming reaction tank 4 is rotated to the other side of the base 1 for the feeding operation.

[0042] During the foaming process in the foaming reaction tank 4, the second motor 41 is started. The second motor 41 drives the stirring rod 42 to rotate, and the stirring rod 42 drives the triangular cam 43 to rotate. When the triangular cam 43 rotates, it simultaneously drives multiple first gears 45 to perform circular motion around the second gear 46 and mesh with the second gear 46. The second gear 46 rotates under force, driving the rotating shaft 44 to rotate. The rotating shaft 44 drives the stirring blade 48 to perform reciprocating circular motion in the foaming reaction tank 4 through the crank 47, so that the cross-linked polyethylene at the edge of the foaming reaction tank 4 can be fully stirred.

[0043] After foaming is completed, the hydraulic rod 51 retracts, the reaction cover 52 is opened, and the material is unloaded. At this time, the drive component changes the position of the two foaming reaction tanks 4 and performs foaming operation again. This cycle is repeated to achieve efficient production with multiple workstations alternating.

[0044] 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.
