DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Please refer to the attached Figure 1-4 The utility model provides an automatic compounding equipment for PVC processing, comprising a mixing tank 1, a feeding hopper 2 is fixedly connected to the top of the side end of the mixing tank 1, a feeding valve 3 is arranged on the feeding hopper 2, which can be used for adding PVC granules, a feeding pipe 4 is fixedly connected to the bottom of the mixing tank 1, a first feeding valve 5 is arranged on the body of the feeding pipe 4, which can be used to control the feeding operation of the mixed materials in the mixing tank 1, two auxiliary agent hoppers 6 are connected to the top of the mixing tank 1 through a metering component, which can be used to store the auxiliary agents required for PVC mixing, a mixing component is arranged in the mixing tank 1, a first anti-blocking component is arranged on the mixing component, and a second anti-blocking component is also arranged on the top of the mixing tank 1;

[0021] The mixing assembly includes a reducer 7. It should be noted that the reducer is a transmission device for low speed and high torque. The power of the high-speed motor is meshed with a large gear on the output shaft through a gear with a small number of teeth on the input shaft of the reducer to achieve the purpose of deceleration. The bottom of the reducer 7 is fixed at the center of the top of the mixing tank 1. A stirring motor 8 is fixed on the top of the reducer 7. The stirring motor 8 is preferably set as a variable frequency motor. The output shaft of the stirring motor 8 is fixedly connected to the input shaft of the reducer 7. The bottom end of the output shaft of the reducer 7 vertically penetrates the top of the mixing tank 1, and a stirring shaft 9 is vertically fixed to the bottom end of the output shaft of the reducer 7. A stirring paddle 10 is fixed on the surface of the stirring shaft 9. Specifically, under the deceleration effect of the reducer 7, when the stirring motor 8 is running, the stirring paddle 10 can be driven by the stirring shaft 9 to rotate slowly in the mixing tank 1, so that the PVC granules and additives added to the mixing tank 1 can be automatically mixed.

[0022] The metering assembly includes two groups of brackets 11, the bottom ends of the two groups of brackets 11 are fixed on the top of the mixing tank 1, and an annular base 12 is fixed on the top of each group of brackets 11. The two auxiliary agent hoppers 6 pass through the two annular bases 12 respectively, and weight sensors 13 are symmetrically fixed on the top of the annular bases 12. The sides of the auxiliary agent hoppers 6 are fixed with connecting pressure plates 14, and the bottom of the connecting pressure plates 14 abuts against the weight sensor 13, that is, the weight sensor 13 can measure the weight of the auxiliary agent hopper 6 and the auxiliary agent stored therein in real time. Therefore, when the auxiliary agent stored in the auxiliary agent hopper 6 is added, the added amount can be measured in real time by the weight sensor 13, so that the staff can understand the specific amount of the auxiliary agent added. The bottom of the auxiliary agent hopper 6 is vertically fixed and connected with an adding pipe 15, and the pipe body of the adding pipe 15 is provided with a second unloading valve 16. A plurality of first through holes 17 are opened on the top of the mixing tank 1, and the bottom end of the adding pipe 15 vertically passes through the first through hole 17, which can be used to add the auxiliary agent in the auxiliary agent hopper 6 to the mixing tank 1;

[0023] The first anti-blocking component includes a vertically arranged threaded rod 18, the top end of the threaded rod 18 is fixed to the bottom end of the stirring shaft 9, and the bottom end of the threaded rod 18 vertically extends into the discharge pipe 4, so when the stirring motor 8 drives the stirring shaft 9 to rotate, the threaded rod 18 can be driven to rotate synchronously, so that the mixed material located at the discharge pipe 4 can be pushed downward, thereby effectively preventing the mixed material in the mixing tank 1 from being blocked when being discharged through the discharge pipe 4;

[0024] The second anti-blocking component includes an arch frame 19, the bottom end of the arch frame 19 is fixed to the top of the mixing tank 1, and a cylinder 20 is symmetrically fixed on the top of the arch frame 19. A second through hole 21 is also symmetrically opened on the top of the arch frame 19, and the bottom ends of the output shafts of the two cylinders 20 pass through the two second through holes 21 respectively. The bottom ends of the output shafts of the two cylinders 20 are vertically fixed with guide rods 22, and the two guide rods 22 are respectively located directly above the two auxiliary agent hoppers 6. It should be noted that when the cylinder 20 runs to the maximum stroke, the guide rod 22 can move downward into the adding pipe 15. Specifically, when the cylinder 20 is running, it can drive the guide rod 22 to rise and fall, thereby applying a downward thrust to the auxiliary agent at the adding pipe 15 in the auxiliary agent hopper 6, thereby effectively preventing blockage when the auxiliary agent in the auxiliary agent hopper 6 is added to the mixing tank 1 through the adding pipe 15.

[0025] It should be noted that the device is electrically connected to an external main controller and 220V AC power, and the main controller can be a prior art device that controls a computer or the like.

[0026] The use process of the utility model is as follows: the staff first adds the required PVC pellets into the mixing tank 1 through the feed hopper 2, and then stores the required additives into the additive hopper 6. At this time, the weight measured by the weighing sensor 13 is the weight of the additive hopper 6 and the total weight of the additives added. Then the staff turns on the stirring motor 8, controls the stirring paddle 10 to rotate in the mixing tank 1, and then opens the second unloading valve 16 of the additive hopper 6 corresponding to the required additive. When the second unloading valve 16 is opened, the additive can be added to the mixing tank 1 through the adding pipe 15. At this time, the amount of weight reduction measured by the weighing sensor 13 is the specific amount of additive added. When the weight measured by the weighing sensor 13 no longer changes, it means that the additive is blocked at the adding pipe 15. At this time, the user can open the corresponding cylinder 22. When the cylinder 20 is running, it can drive the guide rod 22 down. The stirring paddle 10 is used to stir the mixing tank 1 and the mixing hopper 6 so as to prevent the mixing tank 1 from being blocked.

[0027] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
