DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The PVC automatic batching machine is a device used to automatically and accurately mix various raw materials required for the production of PVC products according to a preset formula. The PVC automatic batching machine provided by the utility model weighs the materials in the weighing box 3 through the weighing sensor in the weighing box 3. When a certain amount is reached, the materials are sent into the box body 1 through the connecting pipe and then stirred and mixed by the stirring rod 6. After mixing, they are cleaned by the cleaning mechanism 5. Before cleaning, the protective shell 407 in the protective mechanism 4 needs to be moved upward to prevent it from blocking the nozzle 502.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a PVC automatic batching machine, including a box body 1, the bottom inner wall of the box body 1 is provided with a cleaning mechanism 5, the cleaning mechanism 5 includes a rotating tube 501 rotatably connected to the bottom inner wall of the box body 1, the outer wall of the rotating tube 501 is fixedly connected with a plurality of nozzles 502, a protective mechanism 4 is provided throughout the box body 1, the protective mechanism 4 includes a plug rod 402 plugged into the top of the box body 1, the outer wall of the plug rod 402 is fixed with a limit plate, the top of the plug rod 402 is fixed with a connecting plate 403, the top of the box body 1 is fixed with a telescopic rod 401, the telescopic rod 401 The telescopic end is fixed to the connecting plate 403, and after the insertion rod 402 passes through the top of the box body 1, a fixed shell 404 is fixed to its bottom end, and the inner wall of the fixed shell 404 is rotatably connected with a rotating member 405, and a turntable 406 is fixed to the bottom end of the rotating member 405, and a plurality of protective shells 407 are fixed to the bottom end of the turntable 406, and connecting blocks are fixed on both sides of the protective shell 407, and a plurality of sliding grooves are opened on the surface of the rotating tube 501, and the connecting blocks slide in the sliding grooves, and the protective shell 407 protects the nozzle 502, and a plurality of stirring rods 6 are fixed to the outer wall of the rotating tube 501, and a scraper is fixed to the outer wall of the stirring rod 6.

[0021] It should be noted that when the rotating tube 501 rotates, it drives the stirring rod 6 to stir and mix the materials in the box body 1. When the rotating tube 501 rotates, the protective shell 407 is driven to rotate. The rotation of the protective shell 407 causes the rotating part 405 to rotate in the fixed shell 404. The materials are discharged after mixing. When it is necessary to clean the box body 1, the telescopic rod 401 moves upward to drive the connecting plate 403 to move upward, and the connecting plate 403 moves upward to drive the insertion rod 402 to move, and the insertion rod 402 moves to drive the fixed shell 404 to move. In this way, the protective shell 407 moves upward and no longer blocks the nozzle 502. Thereafter, the rotating tube 501 can be rotated to drive the nozzle 502 to clean in different directions. During the rotation process, the scraper cleans the inner wall of the box body 1.

[0022] like Figure 1 and Figure 4 As shown, the bottom end of the box body 1 is fixedly connected with a discharge pipe, and a valve is installed on the discharge pipe. The bottom end of the box body 1 is installed with a water tank 7, and the top end of the water tank 7 is fixedly connected with a conveying pipe 14, which penetrates the box body 1 and is rotatably connected with the rotating tube 501. The bottom end of the box body 1 is rotatably connected with a rotating sleeve 8, and the rotating sleeve 8 is fixed to the rotating tube 501. The outer wall of the rotating sleeve 8 is fixed with a first rotating wheel 9, and the bottom end of the box body 1 is rotatably connected with a second rotating wheel 10. A belt 11 is arranged between the first rotating wheel 9 and the second rotating wheel 10. The bottom end of the box body 1 is fixed with a mounting frame 12, and the bottom end of the mounting frame 12 is fixed with a motor 13. The output end of the motor 13 penetrates the mounting frame 12 and is fixed with the second rotating wheel 10. An observation window is installed on the box body 1, and a weighing box 3 is installed on the top end of the box body 1. The bottom end of the weighing box 3 is fixedly connected with a connecting pipe, and the connecting pipe is fixedly connected with the box body 1, and a valve is installed on the connecting pipe. A controller 2 is installed on the outer wall of the box body 1 , and the controller 2 is electrically connected to the motor 13 .

[0023] It should be noted that a water pump is installed in the water tank 7, and the water outlet of the water pump is fixedly connected to the delivery pipe 14. The water in the water tank 7 is delivered to the rotating tube 501 through the delivery pipe 14 by the water pump to clean the inside of the box body 1. The second rotating wheel 10 is driven to rotate by the motor 13, and the rotation of the second rotating wheel 10 drives the belt 11 to move. The belt 11 drives the first rotating wheel 9 to rotate. The rotation of the first rotating wheel 9 drives the rotating sleeve 8 to rotate. The rotation of the rotating sleeve 8 drives the rotating tube 501 to rotate.

[0024] Working principle: the motor 13 is started by the controller 2, and the motor 13 drives the second rotating wheel 10 to rotate. The rotation of the second rotating wheel 10 drives the belt 11 to move. The belt 11 drives the first rotating wheel 9 to rotate. The rotation of the first rotating wheel 9 drives the rotating sleeve 8 to rotate. The rotation of the rotating sleeve 8 drives the rotating tube 501 to rotate. When the rotating tube 501 rotates, it drives the stirring rod 6 to stir and mix the materials in the box body 1. When the rotating tube 501 rotates, the protective shell 407 is driven to rotate. The rotation of the protective shell 407 causes the rotating member 405 to rotate in the fixed shell 404. After mixing, the materials are discharged. When it is necessary to clean the box body 1, the telescopic rod 401 moves upward to drive the connecting plate 403 to move upward, and the connecting plate 403 moves upward to drive the insertion rod 402 to move. The movement of the insertion rod 402 drives the fixed shell 404 to move, so that the protective shell 407 moves upward and no longer blocks the nozzle 502. Then the rotating tube 501 can rotate to drive the nozzle 502 to clean in different directions. During the rotation process, the scraper cleans the inner wall of the box body 1.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
