Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a high-speed mixer provided with a slow-speed rotating mechanism. Background Art

[0002] A mixer is a device used to combine different raw materials, commonly used in the food and chemical industries. It uses rotary or forced stirring to mix powdered, granular, or liquid ingredients, ensuring a uniform blend. The mixer's design allows for customized adjustment of stirring speed and time to achieve optimal mixing, improving production efficiency and product quality.

[0003] Publication number CN221386211U is a material mixing mechanism and a three-dimensional motion mixer. The cross-section of the feed port is a frustum that is wide at the top and narrow at the bottom, which makes it convenient for workers to pour materials. The motor drives the rotating barrel to rotate, which in turn drives the mixing frame, rotating rod, and impact block to rotate, so that the material inside the mixer can be quickly turned over and mixed more evenly. When large particles of material are encountered during mixing, the large particles of material are crushed by the action of inertia through the rotation of the mixing frame and the impact block.

[0004] Most of the existing high-speed mixers, when in use, achieve mixing and stirring of materials by rotating the stirring blades driven by the rotating shaft. When the mixer is stirring some sticky materials, it is not convenient to quickly scrape off the materials adhered to the inner wall of the mixer, resulting in waste of materials, and the materials in the lower and upper layers cannot be evenly mixed together, and the effect of stirring and mixing the materials is average. Therefore, we propose a high-speed mixer with a slow-speed rotation mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a high-speed mixer with a slow-speed rotating mechanism to solve the problems in the above background technology that the sticky material is inconvenient to scrape off, resulting in material waste and the lower and upper layer materials cannot be evenly mixed together.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A high-speed mixer equipped with a slow-rotating mechanism comprises a base, a mixing drum mounted on the base, a discharge pipe connected to the bottom end of the outer wall of the mixing drum, and a control valve mounted on the discharge pipe, a driving rod rotatably connected to the inner cavity of the mixing drum, a plurality of stirring blades mounted on the outer wall of the driving rod, and a slow-rotating mechanism for driving the driving rod to rotate.

[0008] The outer wall of the mixing cylinder is connected to a frustum, the outer wall of the frustum is provided with an arc-shaped moving box, and the arc-shaped moving box is provided with a rotating unit for driving the arc-shaped moving box to rotate;

[0009] The outer side wall of the arc-shaped moving box is connected with a linkage rod, and an L-shaped plate is installed at the other end of the linkage rod. An electric telescopic rod is provided on the L-shaped plate. A scraper is installed at the telescopic end of the electric telescopic rod, and an arc-shaped lifting plate is provided at the bottom of the scraper.

[0010] Further: the slow rotation mechanism includes a servo motor, the servo motor is located on the upper surface of the base, and a driving pulley is installed at the output end of the servo motor, a driven pulley is connected to the right side of the inner cavity of the base through a rotating shaft, a belt is placed between the driving pulley and the driven pulley, and the top of the driven pulley is connected to the bottom of the driving rod.

[0011] Further: the rotating unit includes a stepper motor, the stepper motor is located at the top of the arc-shaped moving box, and the output end of the stepper motor is provided with a rotating shaft, the rotating shaft is covered with a traveling gear, the side wall of the truncated table is provided with multiple sets of meshing grooves, and the traveling gear is meshed and connected with the multiple sets of meshing grooves.

[0012] Furthermore: a circular groove is opened on the top wall of the truncated table, an arc block is slidably connected in the circular groove, a connecting rod is installed on the top of the arc block, and the other end of the connecting rod is connected to the upper surface of the arc moving box.

[0013] Furthermore: a bottom plate is provided on the lower surface of the base, and a damping pad is provided on the lower surface of the bottom plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model can drive the active pulley to rotate through the operation of the servo motor on the slow rotation mechanism. Since the active pulley is connected to the driven pulley through the belt, the multiple sets of stirring blades on the driving rod rotate, thereby achieving the stirring and mixing of the materials in the mixing drum. The operation of the stepping motor can drive the traveling gear on the rotating shaft to rotate. Since the traveling gear is meshed and connected with the multiple sets of meshing grooves, and the arc-shaped moving box is limited by the sliding of the connecting rod, the arc block and the circular groove, the linkage rod drives the L-shaped plate to do circular motion, so that the scraper rotates on the inner wall of the mixing drum, thereby achieving the scraping of the materials and avoiding the materials sticking to the inner wall of the mixing drum and causing the waste of materials. The arc-shaped lifting plate can be driven to move up and down by the extension and retraction of the electric telescopic rod, so that the upper and lower layers of the materials in the mixing drum are continuously mixed, thereby effectively improving the material mixing effect.
