Description

Technical Field

[0001] This utility model relates to the field of spark plug processing, and in particular to a spark plug processing sleeve feeding device. Background Technology

[0002] Spark plugs are the main ignition components of gasoline engines in automobiles. They introduce a spark generated by high voltage across the electrode gap into the combustion chamber of the engine to ignite the combustible mixture in the cylinder. To increase the lifespan of spark plugs, a protective sleeve is installed on the outside of the spark plug. The sleeve not only provides insulation but also prevents damage to the spark plug caused by friction or chemical corrosion. Currently, spark plug sleeves are generally made of ceramic. During the manufacturing process, aluminum-containing ceramic powder and other materials are first thoroughly mixed with water. The mixture is then placed in a dryer to dry. The dried mixture is then placed into a mold for compaction and baking. Therefore, whether the mixture is evenly stirred during spark plug sheath feeding is a key step affecting the spark plug. Due to the added moisture, the fed material becomes sticky. This sticky mixture will adhere to the inner wall of the mixing tank during stirring, which prevents the materials from being fully mixed and makes it inconvenient to discharge the mixed material. Therefore, a spark plug sheath feeding device is needed to solve the problem of poor mixing effect and poor discharge efficiency caused by the inability to scrape off the material sticking to the inner wall of the mixing tank during sheath processing. Summary of the Invention

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0020] according to Figures 1 to 4 As shown, a spark plug processing sleeve feeding device includes a mixing tank body 1. A feed inlet and a discharge outlet are respectively provided on the top and bottom of one side of the mixing tank body 1. A mixing chamber is formed inside the mixing tank. A drive motor 5 is fixedly connected to the top of the mixing tank body 1. The output end of the drive motor 5 extends into the mixing chamber and is coaxially fixedly connected to a rotating shaft 7. The bottom end of the rotating shaft 7 is rotatably connected to the bottom of the mixing chamber. A stirring mechanism 8 is axially slidably connected to the surface of the rotating shaft 7. A lifting mechanism 6 is rotatably connected to the top of the rotating shaft 7. The lifting mechanism 6 is fixedly connected to the inner wall of the top of the mixing chamber. The lifting mechanism 6 is used to control the up-and-down displacement of the stirring mechanism 8 on the surface of the rotating shaft 7. A bottom plate 2 is provided at the bottom of the mixing tank body 1. A tilting mechanism 3 and two support legs 4 are fixedly connected to the top of the bottom plate 2. The tilting mechanism 3 is hinged to the bottom of the mixing tank body 1, and the top ends of the two support legs 4 are in contact with the bottom surface of the mixing tank.

[0021] In specific implementation, the feed inlet is located on one side above the mixing tank body 1, and the discharge outlet is located on the other side below the mixing tube body. The tilting mechanism 3 can be used to flip the mixing tank body 1 backward. After flipping, the mixing tank body 1 can more easily discharge the mixed material through the discharge outlet. The top of the rotating shaft 7 is fixedly connected to the output end of the drive motor 5, and the bottom of the rotating shaft 7 is rotatably connected to the bottom of the mixing chamber. The drive motor 5 controls the rotating mechanism to rotate synchronously, driving the mixing mechanism 8 to rotate in the mixing chamber around the rotating shaft 7 as the axis, thereby achieving the mixing of materials. At the same time, the mixing mechanism 8 can scrape the inner wall around the mixing chamber when rotating, which is convenient for scraping off the material adhering to the inner wall and improving the efficiency of material mixing. When the rotating shaft 7 drives the mixing mechanism 8 to rotate, the lifting mechanism 6 can be used to make the mixing mechanism 8 move up and down on the axial surface of the rotating shaft 7. The up and down displacement and synchronous rotation of the mixing mechanism 8 can improve the mixing effect of materials. The two support legs 4 can provide support for the mixing tank body 1 when it is placed horizontally.

[0022] Furthermore, the lifting mechanism 6 includes a cylindrical cam 61, the upper surface of which is fixedly connected to the top of the stirring chamber. The cylindrical cam 61 has through holes extending through its upper and lower parts. The cylindrical cam 61 is rotatably connected to the rotating shaft 7 through the through holes. The surface of the cylindrical cam 61 has a guide groove 611, and a pin 63 is slidably connected in the guide groove 611. A connecting rod 62 is fixedly connected to the outside of the pin 63, and the connecting rod 62 is fixedly connected to the stirring mechanism 8.

[0023] In practical implementation, the top of the cylindrical cam 61 is fixedly connected to the top of the mixing chamber. A through hole is provided at the center of the cylindrical cam 61. The through hole not only facilitates the rotational connection between the cylindrical cam 61 and the rotating shaft 7, but also facilitates the fixed connection between the rotating shaft 7 and the output end of the drive motor 5 through the through hole. Since the cylindrical cam 61 is fixedly connected to the top of the mixing chamber, when the mixing mechanism 8 is rotated under the control of the rotating shaft 7, the connecting rod 62 rotates with the rotation of the mixing mechanism 8. The pin 63 fixedly connected to the top side of the connecting rod 62 is slidably connected in the guide groove 611 on the surface of the cylindrical cam 61. Therefore, when the mixing mechanism 8 rotates, the connecting rod 62, the pin 63 and the guide groove 611 on the surface of the cylindrical cam 61 can make the mixing mechanism 8 move up and down while rotating, so that the mixing mechanism 8 can better mix and stir the materials.

[0024] Furthermore, the stirring mechanism 8 includes a sleeve 81, with a limiting groove 811 extending through the sleeve 81 from top to bottom. A limiting block 71 is fixedly connected to the radial surface of the rotating shaft 7. The sleeve 81 is slidably connected to the rotating shaft 7 through the cooperation of the limiting groove 811 and the limiting block 71. The top of the sleeve 81 is fixedly connected to the bottom end of the connecting rod 62. Multiple main stirring blades 82 and connecting rods 83 are fixedly connected to the radial surface of the sleeve 81. A scraper 84 is fixedly connected to the outside of the connecting rod 83, and the scraper 84 contacts the inner wall of the stirring chamber.

[0025] In practical implementation, the sleeve 81 is slidably connected to the rotating shaft 7 via the limiting groove 811 and the limiting block 71 on the surface of the rotating shaft 7. Due to the limiting fit between the limiting shaft and the limiting groove 811, the rotating shaft 7 can synchronously drive the sleeve 81 to rotate. At the same time, the rotation of the sleeve 81 causes the connecting rod 62 and the pin 63 at the top of the sleeve 81 to engage with the guide groove 611 of the cylindrical cam 61, allowing the sleeve 81 to move axially up and down on the rotating shaft 7. The sleeve 81 can be moved to both sides. Two main stirring blades 82 are respectively provided. The two main stirring blades 82 rotate with the rotation of the sleeve 81 to achieve mixing and stirring of materials. The connecting rod 83 can be set as U-shaped. The two ends of the connecting rod 83 are fixedly connected to the top and bottom of the sleeve 81 respectively. The scraper 84 is fixedly connected to the vertical section of the connecting rod 83 and the outer side of the scraper 84 contacts the inner wall of the mixing chamber. The rotation of the sleeve 81 drives the scraper 84 to rotate on the inner wall of the mixing chamber to achieve the effect of scraping off the material adhering to the inner wall of the mixing chamber.

[0026] Furthermore, a return spring 64 is sleeved on the radial surface of the rotating shaft 7. The top end of the return spring 64 is rotatably connected to the bottom of the sleeve 81, and the bottom end of the return spring 64 is rotatably connected to the bottom of the stirring chamber.

[0027] In practical implementation, the return spring 64 is set at the bottom of the sleeve 81. The upward elastic force of the return spring 64 can provide assistance when the sleeve 81 moves upward, making it easier for the sleeve 81 to move upward.

[0028] Furthermore, the tilting mechanism 3 includes a base 31, which is fixedly connected to the upper surface of the base plate 2. The top of the base 31 is hinged to the bottom of the mixing tank body 1. A hydraulic telescopic rod 32 is provided on one side of the base 31. The fixed end of the hydraulic telescopic rod 32 is hinged to the upper surface of the base, and the telescopic end of the hydraulic telescopic rod 32 is hinged to the bottom of the mixing tank body 1.

[0029] In practice, when the hydraulic telescopic rod 32 extends, it can control the mixing tank body 1 to flip backward with the hinge point with the base 31 as the axis. After flipping backward, the discharge port can be flipped backward and tilted to facilitate the discharge of the mixed material. After the hydraulic telescopic rod 32 is retracted, the mixing tank body 1 is set horizontally. At this time, the mixing tank body 1 is supported by two support columns and the base 31.

[0030] Furthermore, a feeding mechanism 9 is fixedly connected to the top of the mixing tank body 1. The feeding mechanism 9 includes multiple storage tanks 91. A feeding pipe 92 is fixedly connected to the bottom of the storage tank. The discharge end of the feeding pipe 92 is located inside the mixing chamber. A solenoid valve 93 is fixedly connected to the feeding pipe 92 located inside the mixing chamber.

[0031] In practice, multiple storage tanks 91 can be used to store raw materials for processing spark plug sleeves. The raw materials are fed into the mixing tank body 1 through the feed pipe 92 to achieve mixing. At the same time, the solenoid valve 93 is used to control the opening and closing of the feed pipe 92. The solenoid valve 93 can be electrically connected to the controller. By controlling the opening and closing gap of the solenoid valve 93, the feed amount of various raw materials can be controlled to ensure that the raw materials can be mixed and stirred in proportion.

[0032] Furthermore, multiple auxiliary stirring blades 85 are fixedly connected to the inner side of the connecting rod 83.

[0033] In practical implementation, the auxiliary stirring blade 85 can rotate synchronously with the connecting rod 83. Furthermore, since there is a certain gap between the auxiliary stirring blade 85 and the main stirring blade 82, the cooperation between the main stirring blade 82 and the auxiliary stirring blade 85 can make the materials more thoroughly mixed, improving the mixing effect.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
