Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and in particular to a device that facilitates thorough mixing of finished varistor materials. Background Technology
[0002] High-sensitivity resistors (such as high-sensitivity thermistors or varistors) are typically made from specific semiconductor materials, metal oxides, or polymer composites, depending on their type and application. Mixing equipment for high-sensitivity resistors is mainly used for mixing raw materials during the production of thermistors (such as NTC and PTC) and varistors (such as zinc oxide varistors). Existing mixing equipment typically consists of a mixing tank structure, a stirring structure, and a detection structure. Because the stirring structure of existing equipment is usually a simple stirring rod, the material in the center can be sufficiently stirred, but the material squeezed to the periphery, due to its poor flowability, usually remains stationary for a long time and cannot be fully stirred. Therefore, this invention improves upon existing equipment to address these problems. Utility Model Content

[0013] 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.
[0014] Example: See Figure 1-5 This utility model discloses a device for facilitating thorough mixing of finished varistors, comprising a support base 1 located on the left and right sides of an outer cylinder 12. A stirring assembly and a scraping assembly are horizontally mounted on the support base 1. A motor 7 is fixedly installed on one side of the support base 1, connecting the stirring assembly and the scraping assembly. A heating assembly is located inside the outer cylinder 12, with a sealing plug 10 above its outer surface. Both the outer cylinder 12 and the heating assembly are rotatably connected to the stirring assembly. A gearbox 13 is located on one side of the outer cylinder 12, containing a shaking assembly. The modular components facilitate device maintenance and upgrades, improving practicality. The stirring assembly includes a bearing 2 mounted on the support base 1. A central shaft 3 is rotatably connected within the bearing 2. Two connecting frames 4 are symmetrically fixed to the outer surface of the central shaft 3, forming a cross structure. Multiple spiral stirring wires 5 are horizontally fixed at equal angles between the connecting frames 4. One end of the central shaft 3 passes through the bearing 2 and connects to the motor 7, which is fixedly mounted on the support base 1. The scraping assembly includes a double-spiral scraper 6, which is fixed on the connecting frame 4. The outer side of the double-spiral scraper 6 abuts against the inner cylinder 8. The heating assembly includes the inner cylinder 8, with a feed pipe 9 connected to the upper outer side of the inner cylinder 8. The upper outer side of the feed pipe 9 has an external thread, and the upper outer side of the feed pipe 9 is connected to a sealing plug 10 through thread engagement. The bottom surface of the sealing plug 10 is connected to the inner side of the inner cylinder 8. A heating wire 11 is wound around the outer side of the inner cylinder 8. The heating wire 11 passes through the outer cylinder 12 and is connected to the power supply equipment. The outer cylinder 12 is fitted onto the outer side of the inner cylinder 8. Through the cooperation of the stirring assembly and the scraping assembly, it is convenient to stir the material while continuously scraping off the material adhering to the inner wall of the device, thus improving practicality.
[0015] In this utility model, in order to solve the problem that the existing equipment stirring structure cannot fully stir the materials, the following technical solution is adopted: The shaking component includes a gearbox 13, which is installed and fixed on the support base 1. The gearbox 13 has a half gear 14 inside, which is coaxially fixed on the central shaft 3. A transmission gear 15 is provided on one side of the half gear 14, which is rotatably connected to the gearbox 13. A toothed sleeve 16 is fitted on the outer side of the transmission gear 15, which is installed and fixed on the side of the outer cylinder 12. Through the cooperation of the heating component and the shaking component, the device can shake autonomously, thereby fully stirring the internal materials and improving its practicality.
[0016] Working Principle: In the use of this utility model, firstly, power is supplied to all electrical equipment. Then, the material to be mixed is poured into the inner cylinder 8 through the feed pipe 9. Next, the sealing plug 10 is inserted into the feed pipe 9, and then the sealing plug 10 is rotated to seal the inner cylinder 8 through the thread. Then, the motor 7 drives the central shaft 3 to rotate, thereby driving the connecting frame 4 to rotate, causing the spiral stirring wire 5 and the double spiral scraper 6 to rotate, so that the middle part of the material is continuously stirred. At the same time, the material adhering to the inner wall is scraped off and participates in the mixing. While the central shaft 3 rotates, the half gear 14 rotates synchronously, thereby intermittently driving the transmission gear 15 to rotate, thereby causing the gear sleeve 16 to rotate intermittently, and finally causing the outer cylinder 12 to oscillate intermittently, enhancing the flow of the internal material and improving the mixing quality. At the same time, the heating wire 11 continuously heats the internal material, further improving the mixing efficiency. When the material is mixed, the inner cylinder 8 is rotated so that the feed pipe 9 faces downward, thereby facilitating the discharge of the material. At the same time, the double spiral scraper 6 is driven to rotate, driving the material to concentrate in the middle and discharging all the material.
[0017] 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.
