Description

Technical Field

[0001] The invention relates to the field of material filling, and in particular to a filling test device and method. Background Art

[0002] During the filling process of the rotary filling machine, the bottle and the filling valve are required to rotate at the same speed. This synchronous rotation eliminates the time loss during the start-up and stop process of the traditional filling machine, thereby significantly improving the filling speed and production efficiency. However, since the bottle and the filling valve perform circular motion during the filling process, they are subject to the centrifugal force. Centrifugal force is an inertial force that causes an object to move away from the center of rotation when rotating. During the filling process, this force may cause segregation of the mixed material (i.e., the stratification of materials of different densities) and deviation of the filling liquid column (i.e., the material deviates from the expected path during the filling process). The influence of centrifugal force is particularly significant for mixed materials with different densities. Therefore, before the formal filling is carried out, it is necessary to verify the filling effect through a test 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 be posed, and it is also difficult to observe the filling status, which limits the real-time monitoring and adjustment of the filling effect. Summary of the invention

[0003] The object of the present invention is to provide a testing device and method capable of simulating a rotary filling process under static conditions.

[0004] The filling test device described in the present invention includes a base, a mounting plate, a material cylinder, a bottle fixing mechanism, a liquid inlet pipe, a filling valve and a tilt angle adjustment mechanism. The material cylinder is fixed on the mounting plate, and the bottle fixing mechanism for clamping the bottle is located on one side of the mounting plate. The material cylinder and the bottle are connected through a liquid inlet pipe provided with a filling valve; the tilt angle adjustment mechanism includes 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 a rotation center, and the other set of hinges is connected to a retractable adjustment rod, and the other end of the adjustment rod is hinged to the base.

[0005] Furthermore, the adjusting rod includes a first adjusting screw hinged to the hinge of the mounting plate and a second adjusting screw hinged to the base. The first adjusting screw and the second adjusting screw are both connected to the threaded sleeve via threads, and the threaded rotation directions of the first adjusting screw and the second adjusting screw are opposite.

[0006] Furthermore, an angle measuring instrument is provided on a side of the mounting plate away from the bottle fixing mechanism.

[0007] The filling test method of the present invention comprises the following steps: A tilt angle adjustment mechanism is provided, including two sets of hinges for connecting the mounting plate and the base and an adjustment rod for adjusting the mounting plate to be movably hinged relative to the base, one set of hinges is close to the bottle fixing mechanism and serves as a rotation center, and the other set of hinges is connected to a retractable adjustment rod, and the other end of the adjustment rod is hinged to the base, and the tilt angle of the mounting plate is adjusted by the adjustment rod, so that the bottle and the mounting plate are tilted synchronously; A bottle fixing mechanism is provided to clamp and install the bottle on one side of the mounting plate, and the opening of the bottle is aligned with the lower part of the liquid inlet pipe. After the tilt angle adjustment mechanism adjusts the tilt angle of the bottle, the switch of the filling valve is controlled so that the material in the material cylinder placed on the mounting plate can be poured into the bottle; The bottle is tilted by the tilt angle adjustment mechanism to an angle where the gravity direction of the material falling into the bottle is consistent with the direction of the resultant force of the material when the bottle is in a rotating state.

[0008] Furthermore, the tilt angle of the bottle is the angle between the resultant force and the direction of gravity, that is, the angle between the resultant force F and the direction of gravity is a=arctan(Fc / G), where gravity G=m*a, centrifugal force Fc=m*V 2 / R, V is the linear velocity, R is the radius of gyration, Fc=m*V 2 / R.

[0009] The filling test device and method, by providing an inclination angle adjustment mechanism, allows the bottle to adjust its inclination angle, so that the gravity direction of the material during static filling is consistent with the combined force direction of the material during bottle rotation filling. Therefore, its test filling state is very close to the rotation filling state during actual production, so that the filling effect in actual production can be simulated during the test filling stage. Not only does it improve the accuracy of the test filling, but it also reduces the high-speed rotation required during the test filling process, so that the operator can more easily observe the filling process, and promptly discover and adjust possible problems. In addition, reducing high-speed rotation also reduces operational risks and improves the safety of the test filling process. BRIEF DESCRIPTION OF THE DRAWINGS

If the specific posture changes, the directional indication will also change accordingly.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] If there are descriptions involving "first" or "second" etc. in the embodiments of the present invention, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical features of each embodiment (including but not limited to structure, material or characteristics, etc.) can be arbitrarily combined. In order to make the description concise, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0016] like Figure 1 and Figure 2As shown, a filling test device comprises a base 1, a mounting plate 2, a material cylinder 3, a bottle fixing mechanism 4, a liquid inlet pipe 5, a filling valve 6 and a tilt angle adjustment mechanism 7, wherein the material cylinder is fixed on the mounting plate, and the bottle fixing mechanism for clamping the bottle 11 is located on one side of the mounting plate, and the material cylinder and the bottle are connected through a liquid inlet pipe provided with a filling valve; it is characterized in that the tilt angle adjustment mechanism 7 comprises two sets of hinges 8 for connecting the mounting plate and the base, wherein one set of hinges is close to the bottle fixing mechanism and serves as a rotation center, and the other set of hinges is connected to a retractable adjustment rod 9, and the other end of the adjustment rod is hinged to the base.

[0017] A filling test method comprises the following steps: A tilt angle adjustment mechanism 7 is provided, including two sets of hinges 8 for connecting the mounting plate 2 and the base and an adjustment rod 9 for adjusting the movable hinge connection of the mounting plate 2 relative to the base 1, 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 retractable adjustment rod 9, and the other end of the adjustment rod is hinged to the base, and the tilt angle of the mounting plate is adjusted by the adjustment rod, so that the bottle and the mounting plate are tilted synchronously; A bottle fixing mechanism 4 is provided to clamp and install the bottle 11 on one side of the mounting plate 2, and the opening of the bottle is aligned with the lower part of the liquid inlet pipe 5. After the tilt angle adjustment mechanism adjusts the tilt angle of the bottle, the switch of the filling valve 6 is controlled so that the material in the material cylinder placed on the mounting plate can be poured into the bottle; The bottle is tilted by the tilt angle adjustment mechanism to an angle where the gravity direction of the material falling into the bottle is consistent with the direction of the resultant force of the material when the bottle is in a rotating state.

[0018] The filling test device and method, by providing an inclination angle adjustment mechanism, allows the bottle to adjust its inclination angle, so that the gravity direction of the material during static filling is consistent with the combined force direction of the material during bottle rotation filling. Therefore, its test filling state is very close to the rotation filling state during actual production, so that the filling effect in actual production can be simulated during the test filling stage. Not only does it improve the accuracy of the test filling, but it also reduces the high-speed rotation required during the test filling process, so that the operator can more easily observe the filling process, and promptly discover and adjust possible problems. In addition, reducing high-speed rotation also reduces operational risks and improves the safety of the test filling process.

[0019] Furthermore, the adjusting rod 9 includes a first adjusting screw 901 hinged to the hinge of the mounting plate and a second adjusting screw 902 hinged to the base, the first adjusting screw and the second adjusting screw are both connected to the screw sleeve 903 through threads, and the threads of the first adjusting screw and the second adjusting screw rotate in opposite directions. By rotating the screw sleeve, the depth of the first adjusting screw and the second adjusting screw screwed into the screw sleeve can be adjusted, which plays a role in adjusting the distance between the two end points of the screw, thereby quickly adjusting the inclination angle of the mounting plate.

[0020] An angle measuring instrument 10 is also provided on one 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 angle of the bottle and makes the adjustment process more intuitive and quick.

[0021] The tilt angle of the bottle is the angle between the resultant force and the direction of gravity, that is, the angle between the resultant force F and the direction of gravity is a=arctan(Fc / G), 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.

[0022] Therefore, the angle between the resultant force F and the direction of gravity is a=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, which results in the separation of the mixed material and the offset distance of the liquid column being consistent in both filling methods.
