Description

TECHNICAL FIELD

[0001] The present application relates to the field of material filling, in particular to a filling testing device and method. BACKGROUND

[0002] In the filling process of a rotary filling machine, the bottle and the filling valve are required to rotate at the same speed. This synchronous rotation eliminates the time loss in the start-stop process of a traditional filling machine, thereby significantly improving the filling speed and production efficiency. However, since the bottle and the filling valve perform circumferential motion during the filling process, they are subjected to centrifugal force. Centrifugal force is an inertial force that causes an object to move away from the center of rotation when it is rotating. In the filling process, this force can cause the segregation of mixed materials (i.e., the separation of materials of different densities) and the deviation of the filling liquid column (i.e., the deviation of the material from the intended path during the filling process). The effect of centrifugal force is particularly significant for mixed materials containing different densities. Therefore, before formal filling, a test is needed to verify the filling effect by simulating the actual working conditions. The current test method is to install the filling valve and the bottle on a rotating workbench during the test filling. Due to the high-speed rotation of the bottle and the filling valve during the test, safety risks may arise, and it becomes difficult to observe the filling state, which limits the real-time monitoring and adjustment of the filling effect. SUMMARY

[0003] The present application aims to provide a testing device and method that can simulate the rotary filling process under static conditions.

[0004] The filling testing device of the present application comprises a base, a mounting plate, a material cylinder, a bottle fixing mechanism, a liquid inlet pipeline, a filling valve, and an inclination angle adjusting mechanism. The material cylinder is fixed to the mounting plate, and the bottle fixing mechanism for clamping the bottle is located on one side of the mounting plate. The material cylinder is connected to the bottle through the liquid inlet pipeline provided with the filling valve. The inclination angle adjusting mechanism comprises two sets of hinges for connecting the mounting plate and the base. One set of hinges is close to the bottle fixing mechanism and serves as the rotation center, and the other set of hinges is connected to the telescopic adjusting rod. The other end of the adjusting rod is hinged to the base.

[0005] Further, the adjusting rod comprises a first adjusting screw hinged to the hinge of the mounting plate and a second adjusting screw hinged to the base. Both the first adjusting screw and the second adjusting screw are connected to the screw sleeve through threads, and the rotation directions of the threads of the first adjusting screw and the second adjusting screw are opposite.

[0006] Further, the side of the mounting plate away from the bottle fixing mechanism is also provided with an angle measuring instrument.

[0007] The filling testing method of the present application comprises the following steps:

[0008] The inclination angle adjusting mechanism is arranged to include two sets of hinges for connecting the mounting plate and the base and an adjusting rod for adjusting the movable hinge of the mounting plate relative to the base, wherein one set of hinges is close to the bottle fixing mechanism and serves as the rotation center, the other set of hinges is connected with the telescopic adjusting rod, and the other end of the adjusting rod is hinged with the base. The inclination angle of the mounting plate is adjusted through the adjusting rod, so that the bottle and the mounting plate are synchronously inclined.

[0009] The bottle fixing mechanism is arranged to clamp and mount the bottle on one side of the mounting plate, and the opening of the bottle is aligned below the liquid inlet pipeline. After the inclination angle adjusting mechanism adjusts the inclination angle of the bottle, the opening and closing of the filling valve is controlled to enable the material in the cylinder placed on the mounting plate to be filled into the bottle.

[0010] The inclination angle adjusting mechanism is arranged to incline the bottle to an angle at which the direction of the gravity of the material falling into the bottle is consistent with the direction of the resultant force of the material in the rotating state of the bottle.

[0011] Further, the inclination angle direction of the bottle is the included angle between the resultant force and the direction of gravity, that is, the included angle a between the resultant force F and the direction of gravity is arctan (Fc / G), wherein the gravity G = m*a, and the centrifugal force Fc = m* V 2 / R, V is the linear velocity, and R is the radius of rotation. 2 / R.

[0012] The filling test device and method are arranged to adjust the inclination angle of the bottle through the inclination angle adjusting mechanism, so that the direction of the gravity of the material in the static filling state is consistent with the direction of the resultant force of the material in the rotating filling state. Therefore, the trial filling state is very close to the rotating filling state in actual production, so that the filling effect in actual production can be simulated in the trial filling stage. Not only the accuracy of the trial filling is improved, but also the high-speed rotation in the trial filling process is reduced, so that the operator can more easily observe the filling process and timely find and adjust possible problems. In addition, the reduction of high-speed rotation also reduces the operation risk and improves the safety of the trial filling process. BRIEF DESCRIPTION OF DRAWINGS

[0019] As Figure 1 and Figure 2The filling test device comprises a base 1, a mounting plate 2, a cylinder 3, a bottle fixing mechanism 4, a liquid inlet pipeline 5, a filling valve 6 and an inclination angle adjusting mechanism 7, the cylinder is fixed on the mounting plate, the bottle fixing mechanism for clamping a bottle 11 is arranged on one side of the mounting plate, the cylinder is connected with the bottle through the liquid inlet pipeline provided with the filling valve; characterized in that the inclination angle adjusting mechanism 7 comprises two groups of hinges 8 for connecting the mounting plate and the base, one group of hinges is close to the bottle fixing mechanism and serves as a rotating center, the other group of hinges is connected with a telescopic adjusting rod 9, the other end of the adjusting rod is hinged with the base.

[0020] The filling test method comprises the following steps:

[0021] The inclination angle adjusting mechanism 7 is arranged, comprising two groups of hinges 8 for connecting the mounting plate 2 and the base and an adjusting rod 9 for adjusting the movable hinging of the mounting plate 2 relative to the base 1, one group of hinges is close to the bottle fixing mechanism and serves as a rotating center, the other group of hinges is connected with a telescopic adjusting rod 9, the other end of the adjusting rod is hinged with the base, the inclination angle of the mounting plate is adjusted through the adjusting rod, and then the bottle and the mounting plate are synchronously inclined;

[0022] The bottle fixing mechanism 4 is arranged to clamp and mount the bottle 11 on one side of the mounting plate 2, and the opening of the bottle is aligned below the liquid inlet pipeline 5, after the inclination angle adjusting mechanism adjusts the inclination angle of the bottle, the opening and closing of the filling valve 6 is controlled so that the material in the cylinder placed on the mounting plate can be filled into the bottle;

[0023] The bottle is inclined to an angle through the inclination angle adjusting mechanism, at which the direction of the gravity of the material falling into the bottle is consistent with the direction of the resultant force of the material in the rotating state of the bottle.

[0024] The filling test device and method, through the inclination angle adjusting mechanism, the bottle can be adjusted to an inclination angle, so that the direction of the gravity of the material in the static filling is consistent with the direction of the resultant force of the material in the rotating filling, thus the test filling state is very close to the rotating filling state in actual production, so that the filling effect in actual production can be simulated in the test filling stage. Not only the accuracy of the test filling is improved, but also the high-speed rotation in the test filling process is reduced, so that the operator can more easily observe the filling process and timely find and adjust possible problems. In addition, the high-speed rotation is reduced, the operation risk is reduced, and the safety of the test filling process is improved.

[0025] Furthermore, the adjustment rod 9 includes a first adjustment screw 901 hingedly connected to the hinge of the mounting plate and a second adjustment screw 902 hingedly connected to the base. Both the first and second adjustment screws are threadedly connected to a threaded sleeve 903, with the threads of the first and second adjustment screws rotating in opposite directions. By rotating the threaded sleeve, the depth of the first and second adjustment screws inserted into the sleeves can be adjusted, thereby adjusting the distance between the end points of the screws, thereby quickly adjusting the inclination angle of the mounting plate.

[0026] An angle measuring instrument 10 is also provided on the side of the mounting plate away from the bottle fixing mechanism. The tilt angle of the bottle can be read by the angle measuring instrument, which facilitates the adjustment of the bottle angle and makes the adjustment process more intuitive and quick.

[0027] The tilt angle of the bottle is the angle between the resultant force F and the direction of gravity, that is, the angle a=arctan(Fc / G) between the resultant force F and the direction of gravity, where gravity G=m*a and centrifugal force Fc=m*V 2 / R, V is the linear velocity, R is the radius of gyration, Fc= m* V 2 / R. Specifically, for example: linear velocity V = 1.1m / s; gyration radius R = 15m, then Fc = m* V 2 / R=mx1.12 / 1.5=0.81m;G=m*a=9.8m.

[0028] Therefore, the angle a between the resultant force F and the direction of gravity is arctan(Fc / G) = arctan(0.81*m / 9.8*m) = = arctan(0.81 / 9.8) = 4.7°. Therefore, when the bottle is installed at a 4.7° tilt, the direction of gravity acting on the material during static filling is the same as the direction of the resultant force during rotary filling. This results in the same separation of the mixed material and the offset distance of the liquid column in both filling methods.
