DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A self-cleaning rubber powder mixing tank comprises a tank body 1 and a mounting cover 2, a sealing cover 3 is provided on the mounting cover 2 through a feed port, a driving motor 6 is provided on the mounting cover 2 through an adjusting mechanism, a stirring shaft 7 is rotatably provided on the bottom wall of the tank body 1, a plurality of stirring rods 8 are installed on the stirring shaft 7, a plurality of moving grooves 10 are provided on the bottom wall of the mounting cover 2, a transmission cavity 13 is provided inside the mounting cover 2, a reciprocating screw 11 is provided in the moving groove 10, a scraper 9 is threadedly sleeved on the reciprocating screw 11, a limiting rod 12 is further provided in the moving groove 10, the limiting rod 12 realizes the limiting of the scraper 9 to prevent it from rotating with the reciprocating screw 11.

[0022] The scraper 9 is provided with a through hole corresponding to the stirring rod 8, a driving gear 14 is provided in the transmission cavity 13, the reciprocating screw 11 is connected to the driving gear 14 through a transmission mechanism, and the drive motor 6 is connected to the stirring shaft 7 and the driving gear 14 through an insertion mechanism.

[0023] The adjustment mechanism includes a fixing frame 4 installed on the upper end surface of the mounting cover 2, on which a cylinder 5 connected to a drive motor 6 is provided. The fixing frame 4 effectively supports the cylinder 5 and the drive motor 6, and the cylinder 5 can realize the lifting operation of the drive motor 6.

[0024] The transmission mechanism includes a transmission gear 15 installed on the end of the reciprocating screw 11, and the transmission gear 15 is meshed with the driving gear 14. As shown in the figure, the driving gear 14 and the transmission gear 15 are both bevel gears, and the two are vertically meshed to realize power transmission of the drive motor 6.

[0025] The plug-in mechanism includes a plug-in shaft 16 installed on the output shaft of the driving motor 6. The driving gear 14 and the stirring shaft 7 are respectively provided with a plug-in hole 18 and a plug-in groove 17 corresponding to the plug-in shaft 16. When the plug-in shaft 16 is in the plug-in hole 18 and disengaged from the plug-in groove 17, the driving motor 6 is started to realize the synchronous rotation of the reciprocating screw 11. When the plug-in shaft 16 is in the plug-in groove 17 and not in the plug-in hole 18, the driving motor 6 is started to realize the synchronous rotation of the stirring shaft 7.

[0026] The bottom wall of the mounting cover 2 is provided with a movable hole 19 connected to the transmission chamber 13. The movable hole 19 is circular in top view, and the plug-in shaft 16 is square in top view. The diameter of the movable hole 19 is larger than the diameter of the circumscribed circle of the plug-in shaft 16. This design scheme avoids ensuring that the plug-in shaft 16 can rotate smoothly without obstruction when it is at various heights.

[0027] A bolt assembly is installed on the installation cover 2, and a threaded connection groove corresponding to the bolt assembly is provided on the outer wall of the tank body 1. With the help of the bolt assembly, the installation cover 2 can be conveniently disassembled and assembled relative to the tank body 1.

[0028] When the utility model is in use, in the initial state, the scraper 9 is at the end of the moving groove 10 away from the driving motor 6, which is close to the inner wall of the tank body 1 and separated from the stirring rod 8. At this time, the driving motor 6 is at the lowest position, and the insertion shaft 16 is in the insertion groove 17. Therefore, after the driving motor 6 is started, it can drive the stirring shaft 7 to rotate, thereby driving the stirring rod 8 to rotate, so as to achieve the stirring and mixing treatment of the rubber powder in the tank body 1. After the outer wall is stirred and mixed, the bolt assembly is unscrewed to disassemble the mounting cover 2, and the above-mentioned rubber powder can be poured out.

[0029] During the stirring process, the vertically arranged stirring shaft 7 is subjected to the gravity that makes it easier for the rubber powder to fall, while the horizontally arranged stirring rod 8 makes it easier for the rubber powder to adhere to its surface. At this time, if it needs to be cleaned, first start the cylinder 5 to drive the driving motor 6 to rise, and the driving motor 6 drives the plug-in shaft 16 to rise. The plug-in shaft 16 is disengaged from the plug-in groove 17 and is in the plug-in hole 18. At this time, after the driving motor 6 is started, it can drive the driving gear 14 to rotate, and the driving gear 14 can drive the transmission gear 15 to rotate, and the transmission gear 15 drives the reciprocating screw 11 to rotate. When the reciprocating screw 11 rotates, the scraper 9 moves, passes through the hole and passes through the stirring rod 8, so as to realize the scraping operation of the rubber powder adhered to the outer wall of the stirring rod 8.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
