Description

Technical Field

The second transmission shaft 210 has one end connected to the shaft fixing device 220, and the shaft fixing device 220 is arranged on the wall of the left transmission component 201. The other end of the second transmission shaft 210 is installed with a handle stirring device 110. The second transmission shaft 210 is penetrated by a first transmission shaft 230, and a spiral stirring device 120 is fixed on the first transmission shaft 230. Both the first transmission shaft 230 and the second transmission shaft 210 are connected to the transmission device 240. The rotation radius of the spiral stirring device 120 is greater than the rotation radius of the handle stirring device 110. The handle stirring device 110 is arranged on the inner side of the spiral stirring device 120. By adding two handle stirring paddles on the basis of the original spiral belt stirring paddle, the stirring efficiency is increased while the noise of the device is reduced.

[0026] Optionally, in an application scenario of the present invention, 12.5 kg each of silybin and meglumine and 50 kg of starch dextrin are added to a mixer, the trough mixer cover is closed, and the start button is pressed to start stirring the dry materials. After stirring for 10 minutes, an appropriate amount of adhesive is added and stirring is continued for 5 minutes. Due to the setting of the stirring device of the present invention, the wet mixing time can be appropriately reduced, and samples are taken to visually inspect the appearance quality of the mixed soft material and detect the silybin content.

[0027] In this embodiment, the power assembly 400 drives the second transmission wheel 243 to rotate, and the second transmission wheel 243 and the transmission gear 246 are located on the same axis. The first transmission wheel 242 is rotatably arranged on the left transmission assembly 201 and the right transmission assembly 200. The first transmission wheel 242 and the transmission gear 246 are arranged on the same axis, and the two transmission gears 246 are meshed with each other. Therefore, when the power assembly 400 drives the second transmission wheel 243 to rotate, the first transmission wheel 242 is also driven by the transmission gear 246 to rotate, and the second transmission wheel 243 is rotated. The wheel 243 rotates in a different direction from the first transmission wheel 242.

Therefore, the first transmission shaft 230 and the second transmission shaft 210 can perform opposite rotational motions. In this way, the spiral stirring device 120 and the handle-type stirring device 110 can perform opposite rotational stirring motions to increase the stirring effect, thereby increasing the stirring efficiency and reducing the noise of the device.

[0028] In addition, this embodiment arranges a combined structure of a spiral stirring device 120 and a handle-type stirring device 110, wherein the spiral stirring device 120 covers a wide stirring area and the handle-type stirring device 110 is located inside thereof, thereby achieving the effect of eliminating material accumulation and improving the uniformity of material mixing; the spiral stirring device 120 and the handle-type stirring device 110 are used to realize reverse rotation stirring motion, wherein the first transmission shaft 230 and the second transmission shaft 210 respectively drive the two stirring devices to rotate in opposite directions, thereby achieving the effect of accelerating the tumbling and flow of the material, improving the stirring efficiency, and effectively shortening the stirring time.

[0029] It can be understood that in this embodiment, the two handle-type stirring devices 110 rotate in the same direction, but since the left and right second transmission shafts 210 are not connected, in other embodiments, a transmission assembly can be added on one side to allow the two second transmission shafts 210 to rotate in different directions to further increase the stirring effect. In addition, the present invention is connected to the transmission device 240 through a power assembly 400, and the power source on the power assembly 400 is a motor.

[0030] Furthermore, the transmission device 240 includes a transmission disc 241, a first transmission wheel 242, a second transmission wheel 243, a transmission gear 246 and a transmission belt 247. The transmission disc 241 is fixed to the right transmission component 200 and the left transmission component 201. The second transmission wheel 243 is rotatably connected to the transmission disc 241 through an axis. A transmission gear 246 is fixed to one side of the second transmission wheel 243. The first transmission wheel 242 is rotatably fixed to the right transmission component 200 and the left transmission component 201. A transmission gear 246 is fixed to one side of the first transmission wheel 242. The transmission gears 246 are meshed with each other. A third transmission wheel 244 is fixed to the second transmission shaft 210. The third transmission wheel 244 is connected to the first transmission wheel through a transmission belt 247. A fourth transmission wheel 245 is fixed to the first transmission shaft 230. The fourth transmission wheel 245 is connected to the second transmission wheel 243 through a transmission belt 247 to enhance the transmission effect and reduce noise, so as to further reduce the noise of the device.

[0031] Furthermore, it also includes a sealing component 300, which includes an inner sealing shell 310 and an outer sealing shell 320. The inner sealing shell 310 is arranged at the left and right parts of the stirring component 100. A sealing member 330 is provided on the inner side of the inner sealing shell 310. The sealing member 330 is in contact with the second transmission shaft 210. At least two limiting devices 248 are provided on the second transmission shaft 210. The limiting devices 248 are respectively arranged at the left and right parts of the inner sealing shell 310 to seal the stirring outer shell 130 to enhance the sealing performance.

[0032] Furthermore, the outer sealing shell 320 is arranged between the stirring component 100 and the right transmission component 200, and the outer sealing shell 320 is also arranged between the stirring component 100 and the left transmission component 201. The outer sealing shell 320 covers the limiting device 248 and the second transmission shaft 210 to seal the second transmission shaft 210 to enhance the sealing performance.

[0033] Further, the spiral stirring device 120 is provided with two spiral stirring blades, which are fixed to the first transmission shaft 230 through a support rod 121. The width of the spiral stirring blade is at least 5 cm. The handle-type stirring device 110 is provided with two stirring handles 111. The stirring handle 111 includes a wide plate 112 and a narrow plate 113, the surface area of ​​the narrow plate is 5-10 square centimeters, the surface area of ​​the wide plate 112 is 10-20 square centimeters, and the distal ends of the wide plate 112 and the narrow plate 113 are both arc-shaped.

[0034] In this embodiment, through the smaller rotation radius design of the handle-type stirring device 110 and the combination of the wide plate 112 and the narrow plate 113, compared with the traditional single stirring paddle, this embodiment is provided with two identical handle-type stirring devices 110 cooperating with the spiral stirring device 120 to stir the materials, so as to further fully stir the materials, especially to fully mix multiple materials.

[0035] Furthermore, the stirring assembly 100 further includes a stirring housing 130, and both left and right ends of the stirring housing 130 are provided with a certain angle of inclined surface 131. The angle of the inclined surface 131 is 45 degrees. The structure of the stirring housing 130 designed with the 45-degree inclined surface 131 optimizes the material flow path, reduces the accumulation and blockage of materials inside the tank body, and further achieves the effect of avoiding mixing dead corners and improving the mixing effect.

[0036] The present invention adopts two groups of stirring paddles of different forms, so that the gap between the stirring paddles becomes smaller, there is no dead angle during mixing, and the mixture is fully mixed under the action of two pairs of stirring paddles, one positive and one negative, spiral belt type and handle type stirring paddles, thereby improving the mixing uniformity of the product, reducing the mixing time, and improving the production efficiency and product quality. At the same time, because the mixing uniformity is improved, it is not necessary to use a large motor to drive the stirring paddle, and the use of a small-power motor also reduces the noise of the equipment.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
