[0003] To solve the above-mentioned technical problems, this utility model provides an automatic weighing device for alloy casting batching that agitates and breaks up clumps of materials to prevent clumping and affect subsequent weighing, and automatically weighs the batching materials to ensure the accuracy of the weighing.

[0004] This utility model discloses an automatic weighing device for alloy casting batching, comprising a material cylinder, an agitating component, a conveying component, a weighing component, and a discharging component. The agitating component is installed on the left side inside the material cylinder, and the conveying component is installed on the right side of the bottom of the material cylinder. The weighing component is installed at the bottom output end of the conveying component, and the discharging component is installed below the weighing component. Casting materials are added to the material cylinder, and the agitating component agitates the internal materials to break up any clumps, preventing clumping and ensuring accurate weighing. The conveying component transports the materials, and the weighing component automatically weighs them. Once the required weight is reached, the discharging component discharges the material, ensuring weighing accuracy.

[0005] Preferably, the agitating component includes a rotating rod, multiple sets of agitating rods, a spiral conveying blade, and a drive motor. A conical storage chamber is formed inside the material cylinder, and a feed inlet communicating with the conical storage chamber is located on the top left side of the material cylinder. The rotating rod is rotatably mounted on the left side wall of the material cylinder, with its input end connected to the output end of the drive motor. The rotating rod rotates to the left side of the conical storage chamber. Multiple sets of agitating rods are mounted on the outer wall of the rotating rod, with the length of the agitating rods gradually increasing from left to right. The spiral conveying blade is mounted on the right outer wall of the rotating rod. When the feed is added into the material cylinder, the shape of the conical storage chamber causes the feed to flow to the right. The drive motor is started, causing the rotating rod to rotate. The rotating rod then drives the multiple sets of agitating rods to rotate, agitating the feed and breaking up any clumps to prevent clumping and ensure proper weighing. Simultaneously, the rotating rod drives the spiral conveying blade to rotate, conveying the feed to the right.

[0006] Preferably, the conveying component includes a conveying pipe, an outlet cylinder, a servo motor, a rotating rod, a spiral guide vane, and a conical head. The conveying pipe is installed on the bottom right side of the cylinder, and the outlet cylinder is connected to the bottom output end of the conveying pipe. The servo motor is installed on the top right side of the cylinder, and a rotating rod is installed at the output end of the servo motor. The rotating rod rotates in the middle of the conveying pipe, and a conical head is installed at the bottom of the rotating rod. A spiral guide vane is installed on the outer wall of the rotating rod, and the spiral guide vane contacts the inner wall of the conveying pipe. The feed material pushed to the right by the spiral guide vane is concentrated at the right end of the cylinder. The servo motor is started to drive the rotating rod to rotate, and the rotating rod drives the spiral guide vane to rotate, so that the feed material is accurately conveyed and discharged in the conveying pipe. The feed material that falls from the conical head is dispersed to ensure accurate weighing.

[0007] Preferably, the weighing components include a weighing box, a weighing plate, a rotating shaft, a gravity sensor, a force plate, and a controller. The weighing box is installed at the bottom of the discharge cylinder. The weighing plate is installed at both the front and rear ends of the weighing box via the rotating shaft. A gravity sensor is installed in the middle of the weighing plate, and a force plate is installed on top of the gravity sensor. The controller is installed on the left side wall of the weighing box. When the material falls in the conveying pipe, it passes through the discharge cylinder and falls onto the upper surface of the force plate. After the force plate is subjected to force, the gravity sensor weighs the material on the force plate. When the required weight is about to be reached, the servo motor is started to reduce the speed, so as to slow down the downward flow of the material and avoid increasing the gravity due to excessively fast flow, thus ensuring the accuracy of weighing.

[0008] Preferably, the output component includes a second servo motor, a limiting turntable, a guide sleeve, multiple vibrators, a smooth inclined plate, and an output slot. The second servo motor is installed at the front end of the material cylinder, and its output end is connected to the front rotating shaft. The guide sleeve is installed on the rear side wall of the weighing box. A limiting turntable is installed on the outer end of the rear rotating shaft and is rotatably installed inside the guide sleeve. Multiple vibrators are installed at the four corners of the bottom of the weighing plate. The smooth inclined plate is installed at an inclination inside the lower side of the weighing box. A discharge port is opened at the lower part of the right side wall of the weighing box, and the output slot is installed at the discharge port. After reaching the required weight, the servo motor stops rotating, and at the same time, the second servo motor is started to drive the weighing plate to rotate to the left, pouring the material on the surface of the load-bearing plate down. The material falls onto the surface of the smooth inclined plate and is discharged through the discharge port and the output slot. The vibrators are started to make the weighing plate vibrate, avoiding material residue on the surface of the load-bearing plate and improving the feeding efficiency.

[0009] Preferably, it also includes a guide ring, which is installed at the bottom of the discharge cylinder; the guide ring gathers and guides the ingredients to ensure that the ingredients fall into the middle of the force plate, thereby improving the weighing accuracy.

[0010] Preferably, it also includes a feeding hopper and a support rod, with the feeding hopper installed at the top inlet of the material cylinder, the bottom of the support rod installed on the top left side of the weighing box, and the top of the support rod connected to the bottom of the material cylinder; or it also includes a feeding hopper and a support rod, with the feeding hopper installed at the top inlet of the material cylinder, the bottom of the support rod installed on the top left side of the weighing box, and the top of the support rod connected to the bottom of the material cylinder.

A guide ring 23 is installed at the bottom of the output cylinder 8. A feeding hopper 2 is installed at the top inlet of the material cylinder 1. The bottom of the support rod 26 is installed on the top left side of the weighing box 13. The top of the support rod 26 is connected to the bottom of the material cylinder 1. The ingredients are added into the material cylinder 1. The conical shape of the storage chamber causes the ingredients to flow to the right. The drive motor 6 is started, driving the rotating rod 3 to rotate. The rotating rod 3 drives multiple sets of stirring rods 4 to rotate, stirring the ingredients and breaking up any clumps to prevent them from affecting subsequent weighing. At the same time, the rotating rod 3 drives the spiral conveyor blades 5 to rotate, conveying the ingredients to the right. The ingredients pushed to the right by the spiral conveyor blades 5 are concentrated at the right end of the material cylinder 1. The servo motor 9 is started, driving the rotating rod 10 to rotate.

The conical head 12 disperses the falling ingredients, ensuring accurate weighing. As the ingredients fall in the conveying pipe 7, they pass through the discharge cylinder 8 and land on the upper surface of the force plate 20. After the force plate 20 is subjected to force, the gravity sensor 19 weighs the material on the force plate 20.

After reaching the required weight, the servo motor 9 stops rotating, and the second servo motor 16 is activated to rotate the weighing plate 14 to the left, causing the ingredients on the surface of the force plate 20 to fall onto the surface of the smooth inclined plate 24 and be discharged through the outlet and output trough 25.

The rotating rod 3 drives multiple sets of stirring rods 4 to rotate, stirring and breaking up any clumps to prevent further agglomeration. Simultaneously, the rotating rod 3 drives the spiral conveying blades 5 to rotate, conveying the material to the right. The material pushed to the right by the spiral conveying blades 5 is concentrated at the right end of the material cylinder 1. The servo motor 9 is activated, driving the rotating rod 10 to rotate.

After the force plate 20 is subjected to force, the gravity sensor 19 weighs the material on the force plate 20. When the required weight is about to be reached, the servo motor 9 is started to reduce the speed, so that the downward flow of the ingredients is slowed down to avoid increasing the gravity due to excessive flow and to ensure the accuracy of weighing. After the required weight is reached, the servo motor 9 stops rotating and at the same time, the second servo motor 16 is started to drive the weighing plate 14 to rotate to the left, so that the ingredients on the surface of the force plate 20 are poured off.
