Description

Technical Field

[0001] This utility model relates to the field of new materials technology, specifically to a stirring device. Background Technology

[0002] With the continuous development of science and technology, new materials are being applied to various industries. These new materials are categorized into many types based on their structural and functional components. They are all made by mixing multiple materials and undergoing a series of processing steps. During the production process, mixing tanks are frequently used to stir and mix materials. Traditional stirring methods involve a motor driving a central shaft inside the tank to rotate, which in turn drives stirring rods on the outer wall. This results in a unidirectional flow of materials, easily forming eddies and hindering mixing. To improve the stirring effect, patent publication number "CN215086577U" discloses a stirring device for new material production. This device uses two stirring rods rotating around a rotating shaft while simultaneously rotating themselves to stir the raw materials inside the tank. Additionally, two stirring blades at the bottom stir the raw materials at the bottom of the tank, increasing the mixing effect. However, with this method, the stirring positions of the stirring rods and blades are relatively fixed, only able to stir materials in a fixed location. Furthermore, the stirring rods and blades rotate only circumferentially around the tank, resulting in a relatively unidirectional flow of materials and low stirring efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a stirring device that enables two first stirrers to rotate circumferentially and reciprocate radially, thereby changing the stirring range of the new material in the stirring tank. In addition, it cooperates with the second stirrer to rotate axially, which can drive the new material to flow in multiple directions in the stirring tank and improve the stirring efficiency of the new material.

[0004] This utility model provides a stirring device to solve the above-mentioned technical problems, including a stirring tank and a cover. The stirring tank has a feed inlet on its side wall and a discharge outlet at its bottom. A turntable is rotatably mounted at the bottom of the cover. A mounting plate is mounted on the lower side of the turntable. The mounting plate is slidably mounted on the turntable via a sliding structure. The two ends of the mounting plate are provided with first stirring mechanisms extending into the interior of the stirring tank. The mounting plate is also provided with a slot. A first rack and a second rack are provided opposite to each other on the two inner sidewalls of the slot. A shaft with its lower end movably passing through the turntable is fixed at the bottom of the cover. An incomplete gear is provided on the shaft. The first rack and the second rack alternately mesh with the teeth of the incomplete gear. A spindle is movably mounted inside the shaft. A drive bevel gear is provided on the spindle. The shaft has multiple openings. A second stirrer is movably mounted in each opening. The inner end of the second stirrer is provided with a driven bevel gear that meshes with the drive bevel gear. The turntable and the spindle are driven to rotate by a rotation drive mechanism.

[0005] Furthermore, the rotary drive mechanism includes a rotary motor mounted on the top of the cover via a bracket. The output shaft of the rotary motor is provided with a drive sprocket and a drive gear in sequence. The upper end of the spindle extends out of the cover and is provided with a transmission sprocket. The drive sprocket and the transmission sprocket are connected by a chain drive. The turntable is provided with a toothed ring that meshes with the drive gear.

[0006] Furthermore, the sliding structure includes support rods at both ends of the mounting plate and a slide rail on the bottom wall of the turntable, with a slider at the top of the support rods that slides in cooperation with the slide rail.

[0007] Furthermore, the lower end of the mandrel extends through the bottom of the shaft and is equipped with an anchor-type stirring paddle.

[0008] Furthermore, the outer side of the anchor-type stirring paddle is provided with a scraper that contacts the inner wall of the stirring tank.

[0009] Furthermore, the bottom of the cover is provided with an installation ring, a first bearing is provided between the installation ring and the turntable, and a second bearing is provided between the mandrel and the shaft.

[0010] Furthermore, valves are provided on both the discharge port and the inlet port.

[0011] The beneficial effects of this utility model are as follows: the mixing tank is used to hold the new material raw materials, the cover is used to seal the mixing tank, the discharge port at the bottom of the mixing tank is used to discharge the uniformly mixed new material raw materials, and the inlet is used to inject the new material raw materials into the mixing tank. A turntable is rotatably installed at the bottom of the cover. The turntable is driven to rotate by a rotary drive mechanism. The mounting plate is mounted on the turntable through a sliding structure. When the turntable rotates, it drives the mounting plate to rotate circumferentially on the turntable, which in turn drives the first stirring mechanism at both ends of the mounting plate to revolve circumferentially inside the mixing tank, thus stirring and mixing the new material raw materials inside the mixing tank. Furthermore, since the mounting plate can slide on the turntable, and since the first and second racks in the slots of the mounting plate alternately mesh with the incomplete gear on the shaft, and the shaft is fixed to the cover, meaning the incomplete gear is fixed, when the turntable drives the mounting plate to rotate, the first and second racks rotate around the incomplete gear. When the first rack rotates to mesh with the incomplete gear, it will cause displacement on the teeth of the incomplete gear. Similarly, when the mounting plate rotates to the point where the second rack meshes with the incomplete gear, it will cause the first rack to displace in the opposite direction, thereby driving the mounting plate to move back and forth in the radial direction of the mounting plate, and driving the first agitator on the mounting plate to move back and forth in the radial direction of the mixing tank, changing the mixing range of the first agitator on the new material raw material in the mixing tank. Meanwhile, a spindle is movably mounted inside the shaft, and a drive bevel gear is mounted on the spindle. When the spindle rotates under the drive of the rotary drive mechanism, it drives the drive bevel gear to rotate. The drive bevel gear meshes with the driven bevel gear, driving the second agitator inside the opening on the drive shaft to rotate. This causes the second agitator to stir the new material raw material in the axial direction of the mixing tank, enabling material exchange between the upper and lower layers, further improving the fluidity of the new material raw material in the mixing tank, and increasing the stirring efficiency. In summary, using this utility model, the mounting plate can rotate circumferentially with the turntable in the mixing tank, and can also reciprocate in the radial direction of the mixing tank. This drives the first agitator to rotate circumferentially and move radially, changing the stirring range while circumferentially stirring the new material raw material in the mixing tank. Furthermore, in conjunction with the second agitator, it drives the new material raw material in the mixing tank to flow axially, ensuring thorough mixing of the new material raw material in the mixing tank and improving the stirring efficiency.

Detailed Implementation

[0017] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0018] Reference Figures 1 to 3 This utility model provides a mixing device, including a mixing tank 1 and a cover 2. The mixing tank 1 has a feed inlet 11 on its side wall and a discharge outlet 12 at its bottom. Both the feed inlet 11 and the discharge outlet 12 are equipped with valves to facilitate the opening and closing of the feed inlet 11 and the discharge outlet 12. The mixing tank 1 is used to hold new material raw materials, the cover 2 is used to seal the mixing tank 1, the discharge outlet 12 at the bottom of the mixing tank 1 is used to discharge the uniformly mixed new material raw materials, and the feed inlet 11 is used to inject the new material raw materials into the mixing tank 1.

[0019] The bottom of the cover 2 is rotatably equipped with a turntable 3, which is driven to rotate by a rotary drive mechanism 9. Further, the bottom of the cover 2 is provided with a mounting ring 22, and a first bearing 23 is provided between the mounting ring 22 and the turntable 3. The first bearing 23 ensures the installation stability of the turntable 3. A mounting plate 4 is provided on the lower side of the turntable 3. The mounting plate 4 is slidably mounted on the turntable 3 via a sliding structure 5. Further, the sliding structure 5 includes support rods 51 at both ends of the mounting plate 4 and a slide rail 32 on the bottom wall of the turntable 3. The axis of the slide rail 32 passes through the center of the turntable 3. The top of the support rods 51 is provided with a slider 52 that slidably engages with the slide rail 32. At this time, the slide rail 32 and the slider 52 cooperate to restrict the movement direction of the mounting plate 4, causing it to move only radially along the turntable 3. The two ends of the mounting plate 4 are provided with a first stirring mechanism 6 extending into the mixing tank 1. The first stirring mechanism 6 includes a first stirring shaft and several stirring crossbars on the first stirring shaft. At this time, since the mounting plate 4 can only slide along the radial direction of the turntable 3, when the turntable 3 rotates, the mounting plate 4 rotates accordingly, driving the two agitators on the mounting plate 4 to move along the circumference of the turntable 3, and stirring the new material raw materials in the mixing tank 1.

[0020] The mounting plate 4 is also provided with a slot 41. A first rack 42 and a second rack 43 are arranged opposite each other on the two axial inner sidewalls of the slot 41. A shaft 7 with its lower end movably passing through the turntable 3 is fixed to the bottom of the cover 2. An incomplete gear 71 is provided on the shaft 7. The first rack 42 and the second rack 43 alternately mesh with the teeth of the incomplete gear 71. When the turntable 3 drives the mounting plate 4 to rotate, the mounting plate 4 and the turntable 3 slide and engage through the sliding structure 5. During the alternating meshing of the first rack 42 or the second rack 43 with the incomplete gear 71, the mounting plate 4 reciprocates in the radial direction of the mixing tank 1. The mounting plate 4 rotates in the same direction as the turntable 3. Since the shaft 7 is fixed on the cover 2, i.e., the incomplete gear 71 is fixed, when the turntable 3 drives the mounting plate 4 to rotate, the first rack 42 and the second rack 43 rotate around the incomplete gear 71. When the first rack 42 meshes with the incomplete gear 71, the mounting plate 4 will move in the first direction. When the mounting plate 4 rotates to the point where the second rack 43 meshes with the incomplete gear 71, the mounting plate 4 will move in the second direction. The first direction and the second direction are opposite, i.e., the first agitator on the mounting plate 4 moves back and forth in the radial direction of the mixing tank 1, changing the mixing range of the first agitator on the new material raw materials in the mixing tank 1.

[0021] A spindle 8 is movably mounted inside the shaft 7. Furthermore, a second bearing 84 is provided between the spindle 8 and the shaft 7. The second bearing 84 ensures that the spindle 8 can rotate stably within the shaft 7. A drive bevel gear 81 is mounted on the spindle 8. Multiple openings 72 are provided on the shaft 7. A second stirrer 73 is movably mounted within each opening 72. The inner end of the second stirrer 73 is provided with a driven bevel gear 74 that meshes with the drive bevel gear 81. The spindle 8 is driven to rotate by a rotary drive mechanism 9. When the spindle 8 rotates, the meshing of the drive bevel gear 81 and the driven bevel gear 74 drives the second stirrer 73 to rotate, causing the second stirrer 73 to agitate the new material raw material in the axial direction of the mixing tank 1. This allows for material exchange between the upper and lower layers, further improving the fluidity of the new material raw material within the mixing tank 1 and increasing the mixing efficiency.

[0022] The lower end of the mandrel 8 extends movably through the bottom of the shaft 7 and is equipped with an anchor-type stirring paddle 83. Simultaneously, the rotational drive mechanism 9 drives the mandrel 8 to rotate, which in turn drives the anchor-type stirring paddle 83 to rotate, stirring the new material at the bottom of the mixing tank 1, preventing material accumulation and further improving stirring efficiency. Furthermore, the outer side of the anchor-type stirring paddle 83 is equipped with a scraper 831 that contacts the inner wall of the mixing tank 1. The scraper 831 removes material adhering to the inner wall of the mixing tank 1, preventing the new material from adhering to the inner wall, thus reducing waste of the new material and improving stirring efficiency.

[0023] In some embodiments, the rotary drive mechanism 9 includes a rotary motor 91 mounted on the top of the cover 2 via a bracket 21. A drive sprocket 92 and a drive gear 93 are sequentially mounted on the output shaft of the rotary motor 91. The upper end of the spindle 8 extends through the cover 2 and is equipped with a transmission sprocket 82. The drive sprocket 92 and the transmission sprocket 82 are connected by a chain 94. The turntable 3 is equipped with a toothed ring 31 that meshes with the drive gear 93. In this configuration, the rotary motor 91 drives the drive sprocket 92 and the drive gear 93 to rotate. The drive sprocket 92 drives the transmission sprocket 82 to rotate via the chain 94, thereby driving the spindle 8 to rotate. When the paper wheel rotates, the toothed ring 3 on the turntable 3 drives the turntable 3 to rotate. In this way, a single rotary motor 91 can drive the spindle 8 and the turntable 3 to rotate simultaneously.

[0024] In summary, by adopting this utility model, the mounting plate 4 can rotate in the circumferential direction of the mixing tank 1 along with the turntable 3, and can also reciprocate in the radial direction of the mixing tank 1. This drives the first agitator to rotate circumferentially and move radially at the same time, so as to change the mixing range while circumferentially mixing the new material raw materials in the mixing tank 1. In addition, it works with the second agitator 73 to drive the new material raw materials in the mixing tank 1 to flow in the axial direction, so that the new material raw materials in the mixing tank 1 are fully mixed and the mixing efficiency of the new material raw materials is improved.
