AI Technical Summary
In the prior art, the height of the first and second stirring shafts is fixed. When the stirring drum is deep, it cannot fully contact the raw materials in different flow layers, which affects the overall uniformity of mixing.
The adjustment mechanism includes a motor, a lead screw, and a guide frame. The motor drives the lead screw to rotate, causing the stirring shaft to rise and fall with the guide frame, thus changing the stirring height. Combined with a buffer plate, the lifting range is limited to achieve thorough mixing of different flow layers. At the same time, a heating jacket and a purification box are set up, and an axial flow fan is used to extract the gas for purification treatment.
It achieves full contact between the stirring shaft and raw materials in different flow layers, improves mixing uniformity, and reduces gas pollution through the purification system, thus protecting the environment.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: Refer to Figures 1-4 As shown: A dyeing and printing raw material mixing device includes a mixing drum 3. A limit frame 5 is attached to one side of the mixing drum 3. An adjustment mechanism is provided on one side of the limit frame 5. The adjustment mechanism includes a motor 12, a lead screw 13, and a guide frame 21. A drive assembly 6 is bolted to the top of the motor 12. A mixing shaft 16 is rotatably connected to the bottom of the drive assembly 6. The bottom of the drive assembly 6 is fixedly connected to the guide frame 21. The guide frame 21 is threaded to the lead screw 13. A reinforcing frame 22 is rotatably connected to the top of the lead screw 13. A support frame 4 is fixedly connected to one side of the reinforcing frame 22. A buffer plate 17 and a reinforcing plate 20 are fixedly connected to one side of the support frame 4. A buffer plate 28 is connected to the top of the reinforcing plate 20 through a spring telescopic rod. The buffer plate 28 is slidably connected to the support frame 4. A motor 29 is fixedly connected to one side of the support frame 4. One end of the output shaft of the motor 29 is fixedly connected to the lead screw 13.
[0024] The synchronous belt inside the drive assembly 6 is driven by motor 12, which provides power for the rotation of the stirring shaft 16. The support frame 4 supports motor 19, which in turn provides power for the rotation of the lead screw 13, facilitating the lifting and lowering adjustment of the guide frame 21 along the support frame 4. The stirring shaft 16 and the guide frame 21 are connected by the drive assembly 6, so the stirring shaft 16 can lift and lower synchronously with the guide frame 21. When the guide frame 21 lifts and lowers, it can overlap with buffer plate 17 and buffer plate 18 respectively, limiting the lifting and lowering range of the guide frame 21 and reducing the impact of the guide frame 21 on the support frame 4. Through the lifting and lowering of the stirring shaft 16, it can contact the raw materials at different heights inside the mixing drum 3, thereby improving the uniformity of the raw material mixing.
[0025] Example 2: Figures 1-3 As shown, a heating sleeve 14 is fixedly connected to the inner wall of the stirring drum 3, and a heating tube 15 is embedded inside the heating sleeve 14. Two sealing covers 7 are snapped onto the top of the stirring drum 3. The sealing covers 7 are penetrated by the stirring shaft 16, and the sealing covers 7 and the stirring shaft 16 are slidably connected. A purification box 2 is fixedly connected to one side of one of the sealing covers 7. A connecting pipe 11 is embedded inside the purification box 2. One end of the connecting pipe 11 passes through the side wall of the purification box 2 and the sealing cover 7 in sequence. A filter plate 10 is snapped onto the inner wall of the purification box 2. An adsorption plate 9 and an adsorption plate 8 are provided on the top of the filter plate 10. Both the adsorption plate 9 and the adsorption plate 8 are snapped onto the inner wall of the purification box 2, and an axial flow fan 1 is fixedly connected to the top of the purification box 2.
[0026] The heating jacket 14 and heating tube 15 can be used to adjust the temperature inside the stirring drum 3, which is convenient for heating the raw materials during stirring. The stirring drum 3 can support the bottom of the two sealing caps 7, which is convenient for the installation and removal of the sealing caps 7 on the top of the stirring drum 3. The connecting pipe 11 can connect the stirring drum 3 and the purification box 2, so that the gas inside the stirring drum 3 can be extracted and sent into the purification box 2 by the axial flow fan 1. The filter plate 10 can filter the impurities in the gas. The adsorption plate 2 9 and adsorption plate 1 8 can doubly adsorb harmful substances and odors in the gas, thereby reducing the interference of gas discharge to the surrounding environment.
[0027] The operating method and working principle of this device are as follows: First, place the printing and dyeing raw materials to be stirred into the stirring drum 3. Rotate the bolts on the limiting frame 5 to limit and fix the stirring drum 3. Install two sealing covers 7 on the top of the stirring drum 3. Use the external controller to start the heating tube 15 to heat the inside of the stirring drum 3. The drive assembly 6 has a synchronous belt structure installed inside. Motor 12 drives the synchronous belt to run. The stirring shaft 16 rotates at the bottom of the drive assembly 6 to stir the raw materials. During the stirring process, Motor 29 drives the lead screw 13 to rotate. The guide frame 21 is adjusted up and down under the drive of the lead screw 13. The stirring shaft 16 rises and falls synchronously with the guide frame 21. During the rising and falling process, buffer plate 17 and buffer plate 28 limit the rising and falling range of the guide frame 21 respectively. During stirring, the gas generated inside the stirring drum 3 is extracted by the axial flow fan 1 and sent into the purification box 2 through the connecting pipe 11. After being filtered by the filter plate 10, it is then adsorbed by the activated carbon adsorption plate 29 and the silica gel adsorption plate 8 before being discharged.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
