Before being used, admixtures often need to be accurately weighed to ensure that the dosage meets process requirements, thereby guaranteeing product quality and production stability. Currently, there are many types of admixture weighing devices on the market, but most have some shortcomings.
[0003] Traditional additive weighing devices often leave additive residues inside the weighing hopper after the weighing task is completed. If these residues are not cleaned in time, they will not only affect the accuracy of the next weighing, but may also cause cross-contamination between different additives, thereby affecting the quality of the final product.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] This utility model discloses an additive weighing device.
[0034] Example 1: According to the appendix Figure 1-3 As shown, it includes a weighing hopper 1 and an additive feeding unit 2. The additive feeding unit 2 is configured in multiple groups, and the multiple groups of additive feeding units 2 are arranged above the weighing hopper 1. A cleaning unit 3 is provided on the weighing hopper 1.
[0035] Cleaning unit 3 includes:
[0036] A rinsing assembly 31 is disposed above the weighing hopper 1 and is used to clean the inside of the weighing hopper 1.
[0037] The drain pipe 32 is located at the bottom of the weighing hopper 1 and is used to drain water and dirt from the weighing hopper 1.
[0038] Furthermore, a discharge pipe 11 is fixedly connected to the bottom of the weighing hopper 1, and a first solenoid valve 12 is installed on the discharge pipe 11. The first solenoid valve 12 is used to control the opening and closing of the discharge pipe 11.
[0039] Furthermore, the admixture feeding unit 2 includes:
[0040] Additive tank 21 is positioned above weighing hopper 1;
[0041] Feed pipe 22, one end of which is fixedly connected to the bottom of admixture tank 21, and the other end of which is fixedly connected to the side wall of weighing hopper 1;
[0042] The second solenoid valve 23 is installed on the feed pipe 22 and is used to control the opening and closing of the feed pipe 22. When weighing is required, the additive in the additive tank 21 enters the weighing hopper 1 through the feed pipe 22. The second solenoid valve 23 on the feed pipe 22 controls the opening and closing of the feed pipe 22, thereby precisely controlling the amount of additive entering the weighing hopper 1. When the additive in the weighing hopper 1 reaches the set weight, the second solenoid valve 23 is closed, and feeding stops.
[0043] After weighing is completed, the first solenoid valve 12 on the discharge pipe 11 is opened, and the additive in the weighing hopper 1 is discharged through the discharge pipe 11 for subsequent production processes.
[0044] Example 2: According to the appendix Figure 1-3 As shown, it includes a weighing hopper 1 and an additive feeding unit 2. The additive feeding unit 2 is configured in multiple groups, and the multiple groups of additive feeding units 2 are arranged above the weighing hopper 1. A cleaning unit 3 is provided on the weighing hopper 1.
[0045] Cleaning unit 3 includes:
[0046] A rinsing assembly 31 is disposed above the weighing hopper 1 and is used to clean the inside of the weighing hopper 1.
[0047] The drain pipe 32 is located at the bottom of the weighing hopper 1 and is used to drain water and dirt from the weighing hopper 1.
[0048] Furthermore, the rinsing assembly 31 includes:
[0049] Fixed base 311, fixed base 311 is fixedly connected to the top of weighing hopper 1;
[0050] Rotary seat 312 is rotatably connected to fixed seat 311;
[0051] The nozzle 313 has its top end passing through the fixed base 311 and is fixedly connected to the rotating base 312.
[0052] A flushing nozzle 314 is provided, and multiple flushing nozzles 314 are fixedly connected at equal intervals to the bottom side of the nozzle 313.
[0053] A water supply pipe 315 is rotatably connected at one end to a rotating base 312. By rotating the rotating base 312, the spray pipe 313 is rotated, and multiple rinsing nozzles 314 rinse the inside of the weighing hopper 1 from different angles. The rinsing water and dirt are discharged through the drain pipe 32, which can more comprehensively and thoroughly remove residual additives and dirt from the weighing hopper 1, resulting in better cleaning effect, effectively avoiding cross-contamination, and ensuring the accuracy of the next weighing.
[0054] Furthermore, horizontal blocks 3121 are fixedly connected to both sides of the rotating base 312.
[0055] Furthermore, the nozzle 313 and the water supply pipe 315 are connected through the fixed seat 311 and the rotating seat 312.
[0056] Furthermore, the drain pipe 32 is fixedly connected to the side of the discharge pipe 11, and the drain pipe 32 is inclined. The drain pipe 32 is connected to the discharge pipe 11, and the inclined arrangement of the drain pipe 32 and its connection with the discharge pipe 11 facilitates the smooth discharge of water and dirt.
[0057] Furthermore, a third solenoid valve 321 is installed on the drain pipe 32, which controls the opening and closing of the drain pipe 32. When cleaning the weighing hopper 1 is required, the discharge pipe 11 is closed by the first solenoid valve 12, and the drain pipe 32 is opened by the third solenoid valve 321. The water supply pipe 315 is connected to the water source, and water enters the rotating seat 312 through the water supply pipe 315, then enters the spray pipe 313, and is sprayed out from multiple rinsing nozzles 314 to rinse the inside of the weighing hopper 1. At the same time, rotating the cross block 3121 causes the rotating seat 312 to rotate, which in turn drives the spray pipe 313 to rotate, so that the rinsing nozzles 314 can thoroughly clean the inside of the weighing hopper 1 from different angles. The water and dirt generated during the cleaning process are discharged through the drain pipe 32 to ensure the smooth progress of the cleaning process. After cleaning is completed, the third solenoid valve 321 is closed to stop the draining.
