[0033] Further, the inner wall of the feeding cylinder 2 is provided with a cleaning mechanism, which includes a cleaning assembly and a limiting assembly. The cleaning assembly includes a connecting rod 51, which is arranged at the center of the protective cover 21 and serves to connect a scraper 52, so that the scraper 52 can rotate around the connecting point of the connecting rod 51 and the protective cover 21. The connecting rod 51 is rotatably connected to the inner wall of the protective cover 21 at the upper portion, and the outer side of the connecting rod 51 is fixedly connected with the scraper 52. The scraper 52 is arranged in a curved spiral shape, and the outer side of the scraper 52 is made of silica gel material, which can better fit the inner wall curve of the feeding cylinder 2, increase the contact area with the inner wall, and improve the cleaning effect. At the same time, the silica gel material has certain flexibility, can adapt to different degrees of inner wall dirt cleaning, has good wear resistance and corrosion resistance, can be used for a long time in harsh environment of chemical raw materials without being easily damaged, and effectively scrapes various raw material residues adhered to the inner wall of the feeding cylinder 2.

[0034] Reference Figure 3 and Figure 6The inner wall of the connecting rod 51 is sleeved with a rotating rod 53, which rotates under the driving of the driving motor 9 and can drive the stirring assembly to realize the stirring function. At the same time, through the cooperation of the limiting teeth 54 and the limiting groove 55, the connecting rod 51 is driven to rotate, thereby driving the scraper 52 to clean the inner wall of the feeding cylinder 2. The upper inner wall of the rotating rod 53 is slidably connected with a sliding rod 7, which provides upward movement space for the rotating rod 53, so that the limiting teeth 54 can be inserted into the limiting groove 55. The upper part of the sliding rod 7 is fixedly connected to the lower side of the output shaft of the driving motor 9. The lower side of the connecting rod 51 is provided with a limiting groove 55. The lower part of the rotating rod 53 is provided with a limiting tooth 54 on one side close to the limiting groove 55. When the rotating rod 53 moves up and down, the relative movement of the limiting tooth 54 in the limiting groove 55 can drive the connecting rod 51 to rotate around the connecting point of the upper part of the connecting rod 51 and the protective cover 21, thereby making the scraper 52 perform wall scraping action to ensure the stability and reliability of the cleaning effect.

[0035] Referring to Figure 2 , Figure 4 and Figure 5 , the limiting assembly includes a fixed disc 61, which is provided with a tapered slope below. When the sliding block 63 moves, the ball 64 on the sliding block 63 will contact and be extruded by the tapered slope of the fixed disc 61. The extrusion will cause the rotating rod 53 to move upward, so that the limiting tooth 54 can be inserted into the limiting groove 55 to start the cleaning action of the scraper 52. The fixed disc 61 is fixedly connected to the upper outer side of the rotating rod 53. The upper part of the protective cover 21 is fixedly connected with a base 62 for supporting the sliding block 63. The inner wall of the base 62 is slidably connected with a sliding block 63, which moves under the driving of a threaded rod 65. The upper inner wall of the sliding block 63 is provided with a ball 64, which rotates in the inner wall of the sliding block 63 and directly contacts the fixed disc 61. By rotating, friction can be reduced. The inner wall of the base 62 is rotatably connected with a threaded rod 65, which is threadedly connected to the inner wall of the sliding block 63 on the outer side. By rotating, the position of the sliding block 63 can be accurately controlled. The right side of the threaded rod 65 is provided in a regular hexagonal shape, which is convenient for operators to rotate the threaded rod 65 with tools.

[0036] Referring to Figure 2 , Figure 3 and Figure 6 , the lower outer side of the rotating rod 53 is provided with a stirring assembly. The stirring assembly includes a stirring rod 81, which is fixedly connected to the lower outer side of the rotating rod 53 and rotates under the driving of the rotating rod 53. The stirring rod 81 is provided with four groups. The stirring rod 81 is inclined, which can generate upward or downward component force during rotation, so that the material inside the feeding cylinder 2 is stirred to prevent the raw materials from agglomerating, precipitating or stratifying. The upper part of the stirring rod 81 is vertically fixedly connected with a vertical rod 82, which is provided with multiple groups and plays a role in stabilizing the stirring flow field and enhancing the stirring intensity during stirring.

[0037] Working principle: in use, the driving motor 9 is started, and its output shaft drives the sliding rod 7 fixedly connected therewith to rotate, the rotation of the sliding rod 7 is transmitted to the rotating rod 53 connected therewith in sliding mode, so that the rotating rod 53 rotates, and the four groups of inclined stirring rods 81 fixedly connected to the lower outer side of the rotating rod 53 rotate under the driving of the rotating rod 53, so that the material is tumbled in the inside of the feeding cylinder 2, effectively preventing the agglomeration, sedimentation or stratification of the raw materials.

[0038] When it is necessary to clean the inner wall of the feeding cylinder 2, the operator uses a special tool such as a hex wrench to rotate the threaded rod 65, and the rotation of the threaded rod 65 will make the sliding block 63 slide in the inner wall of the base 62, the rolling balls 64 arranged on the upper inner wall of the sliding block 63 move with the sliding block 63 and contact the conical inclined surface below the fixed disc 61, and with the extrusion of the rolling balls 64 on the conical inclined surface, the fixed disc 61 drives the rotating rod 53 to move upward.

[0039] When the limiting teeth 54 are completely inserted into the limiting groove 55, the rotating rod 53 is driven to rotate around the connecting point between the upper part thereof and the protective cover 21 by the cooperation of the limiting teeth 54 and the limiting groove 55 under the continuous rotation of the driving motor 9, and the scraper 52 on the outer side of the connecting rod 51 is scraped and cleaned on the inner wall of the feeding cylinder 2, effectively scraping off various raw material residues adhered to the inner wall of the feeding cylinder 2, ensuring the cleanliness of the feeding cylinder 2, so as to ensure the accuracy of the next feeding and prevent the residual raw materials from causing pollution or interference to the subsequent reaction, after cleaning, the threaded rod 65 is rotated in reverse, the sliding block 63 moves in reverse, the extrusion of the rolling balls 64 on the fixed disc 61 is released, and the rotating rod 53 returns to the initial position under the action of its own gravity, and the cleaning mechanism stops working.

[0040] Finally, it should be pointed out that: the above-mentioned only for the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included in the protection scope of the present application.
