Description

Technical Field

[0001] The present invention relates to a system for controlling harmonic, frequency, and amplitude parameters in a vibration device.

[0002] More specifically, the present invention relates to transferring rotational motion obtained from a drive assembly to a shaft capable of moving on a surface. The shaft is configured to move at an angle relative to the drive shaft on the surface, thereby adjusting harmonic, frequency, and amplitude parameters in the system. Background Art

[0003] Ore enrichment or mineral processing refers to the process used to separate valuable minerals or metals from ores. A vibrating table is an important piece of equipment used in the above ore enrichment process. In particular, vibrating tables are used to separate valuable or heavy minerals, such as gold, silver, tin, tungsten, zircon, etc., from ore mixtures. This process is typically carried out to concentrate valuable minerals in the raw ore mined from mines.

[0004] Various parameters are involved in the process of further concentrating minerals in ore enrichment equipment. Among them, frequency, amplitude, the variation of amplitude over time, and adjustable harmonic motion are key factors. Vibrating tables separate minerals using vibration based on density differences during the enrichment process. However, the ability to adjust the amplitude settings and provide harmonic motion in the vibrating table affects the success rate of the above process, such as the process of separation based on density.

[0005] The inability to adjust the required amplitude or the inability to provide the required harmonic motion to the output of the machine has a negative impact on operational efficiency. Achieving the required motion and amplitude on a vibrating table requires a high level of technical equipment. Therefore, factors such as precise control systems, powerful vibration motors, and material quality used in machine design result in increased costs.

[0006] Document RS63452B1 discloses a winding machine for winding a stretch film onto a coil. The machine is used in a plastic film production line for producing reels made by continuously winding film strips. However, this document does not provide an explanation regarding the adjustment of amplitude and simple harmonic motion on a vibrating table.

[0007] A system is disclosed in document CN217126205U, which is designed to effectively shorten the transportation path, reduce movement obstacles during transportation, and improve the efficiency of feeding and unloading. In this document, an X-axis drive mechanism is used to drive a moving frame backward along the X-axis direction relative to a crossbeam carrier. However, this document does not provide an explanation regarding the adjustment of amplitude and simple harmonic motion of an oscillating table.

[0008] Document CN211754465U discloses a structure of a shaker (vibration table) as a laboratory instrument applicable to fields such as electrophoresis gel decolorization / staining, sample mixing, molecular hybridization, immunoprecipitation, protein inhibition, cell culture, etc. This document aims to reduce noise during operation and extend the service life of the motor.

[0009] In summary, considering the disadvantages of the vibration tables used in the prior art, such as the inability to provide the required simple harmonic motion, frequency, and amplitude, and the high cost of achieving these conditions when they are met, a practical system design is needed that allows adjustable harmonic motion, that is, motion following a graph of any harmonic shape, provides variable amplitude, variable frequency, and linear reciprocating (back-and-forth) motion. Summary of the Invention

[0012] Another object of the present invention is to adjust the harmonic parameters of the motion generated in the drive assembly by means of a disk member having a slope difference between its lower end and upper end and a shaft member moving on the disk member.

[0013] Another object of the present invention is to eliminate the non-adjustable simple harmonic motion caused by the uneven slopes on the surface of the disk member.

[0014] The present invention also aims to provide a system that allows linear (back-and-forth repetitive) motion following a harmonic motion graph, which harmonic motion graph can be selected by an adjustable attachment.

[0015] In addition, the present invention aims to provide a system for converting rotational motion into linear motion, where the amplitude can be adjusted.

[0044] The present invention relates to a system for adjusting harmonic, frequency and amplitude parameters. The system transmits the rotational motion received from the drive assembly T to a shaft member 20 capable of moving on the surface 10.1 of a disk member 10, and adjusts the harmonic, frequency and amplitude parameters by moving the shaft member 20 on the surface 10.1. The shaft member 20 is configured to be inclined at a specific angle on different axes relative to the drive shaft 30. In other words, the present invention relates to a system that includes a drive assembly T capable of generating rotational motion; a motion transmission assembly H that converts this (rotational) motion into linear motion transmitted to the output shaft 50 and controls the harmonic, frequency and amplitude parameters in a vibration device. The system is specifically configured to control the harmonic, frequency and amplitude parameters of the rotational motion obtained from the drive assembly T.

[0045] The present invention basically includes at least one disk member 10, at least one bolt 10.3, at least one shaft member 20, at least one bearing 20.1, at least one joint pin 20.2, at least one drive shaft 30, at least one rod 40, at least one output shaft 50, at least one motion transmission assembly H, and at least one drive assembly T. The disk member 10 includes at least one surface 10.1. The motion transmission assembly H includes at least one ball joint k and at least one piston assembly p.

[0046] The combination of the disk member 10 and the shaft member 20 provides the generation of the required harmonic motion. The disk member 10 is preferably configured with a horizontal cylindrical geometry including a cavity 10.2, and can be configured with different geometries according to preferences and requirements. The cavity 10.2 is optional and may not exist in alternative configurations of the present invention.

[0047] The bottom surface of the above-mentioned horizontal cylinder (disk member 10) on one side of the rod member 40 is configured as a right angle, and its bottom surface on one side of the shaft member 20 is configured to form a specific angle. In other words, the bottom surface on one side of the shaft member 20 is constructed to have a certain inclination angle in different axial directions with respect to the drive shaft 30. The angle is formed between the first axis A and the second axis B. This angle means a specific inclination. In this article, the above-mentioned first axis A represents the axis of the shaft member 20, which represents the axis extending along the shaft member 20 at the position where the shaft member 20 is located. The above-mentioned second axis B represents the axis of the drive shaft 30, which represents the axis extending along the drive shaft 32 at the position where the drive shaft 31 is located. The change in the angle between the first axis A and the second axis B corresponds to the change in the amplitude. In an embodiment of the present invention, the disk member 10 is fixed by adjusting the angle value to the required amplitude. In a preferred embodiment of the present invention, the position of the disk member 10 can be changed with the help of the rod 40, and thus, the angle value can be changed. Thereby, the amplitude value is adjusted.

[0048] The bottom surface of the disk member 10 (a horizontal cylinder having a cavity 10.2 inside) is referred to as the surface 10.1. In another embodiment of the present invention, based on the desired harmonic motion to be obtained / generated in the output shaft 50, the above-mentioned surface 10.1 includes indentations, protrusions, sharp or smooth designs. Different configurations of the surface 10.1 cause the shaft member 20 moving on the surface 10.1 to cooperate with the concave or convex portions on the surface according to the design of the surface 10.1, thereby forming different harmonic motions.

[0049] The disk member 10 is preferably connected to the required vibration device by bolts 10.3. The bolts 10.3 are preferably attached near the middle of the disk member 10 such that the disk member 10 can be connected to the vibration device. The bolts 10.3 can perform a rotational motion along a certain axis based on the connection points with the disk member 10 and function as hinges for the disk member 10. When the bolts 10.3 function as hinges during the possible forward and backward movement of the rod 40, the disk member 10 can change its angle by moving. More specifically, the disk member 10 includes at least one surface 10.1, which is configured to have a certain slope at different axes with respect to the drive shaft 30 and enables the shaft member 20 to move. Due to the motion generated by the drive assembly T, the shaft member 20 performs a rotational motion on the surface 10.1, thereby being able to generate different amplitudes, frequencies, and harmonics.

[0050] The above-mentioned shaft member 20 is connected to a drive shaft 30 passing through a cavity 10.2 in the above-mentioned disk member 10 by a joining pin 20.2. The shaft member 20 is preferably connected to the drive shaft 30 near its middle part. The shaft member 20 is cylindrical, and bearing 20.1 structures are respectively provided at one end and the other end of the cylindrical structure to ensure its smooth movement on the surface 10.1. The position of the shaft member 20 is set such that when the shaft member 20 moves, both bearings 20.1 can contact the above-mentioned surface 10.1 and rotate on the surface 10.1. The shaft member 20 is preferably connected to a motion transmission assembly near either of its ends, in other words, connected to the motion transmission assembly H near either bearing 20.1. In this article, the shaft member 20 is connected to the motion transmission assembly H through a spherical joint k. The above-mentioned bearing 20.1 is preferably designed to be cylindrical, and when the shaft member 20 moves, the bearing 20.1 contacts the surface 10.1 and performs a rotational motion. The joining pin 20.2 ensures the connection between the shaft member 20 and the drive shaft 30. More specifically, the shaft member 20 includes a bearing 20.1 capable of moving on the above-mentioned surface 10.1. It combines the motion received from the drive shaft 30, rotates along the trajectory on the above-mentioned surface 10.1, and transmits the motion generated on the surface 10.1 to the motion transmission assembly H.

[0051] The above-mentioned drive shaft 30 transmits the motion (such as rotational motion) generated by the drive assembly T to the above-mentioned shaft member 20. One end of the drive shaft 30 is connected to the drive assembly T, and the other end contacts the shaft member 20. The above-mentioned drive shaft 30 is connected to the shaft member 20 through a joining pin 20.2 passing through a cavity 10.2 in the above-mentioned disk member 10. By adjusting the number of revolutions of the motion transmitted from the drive assembly T to the drive shaft 30, the frequency value of the required motion can be controlled.

[0052] One end of the above-mentioned rod member 40 is connected to a preferably short (in terms of length) vertical bottom surface of the above-mentioned disk member 10, and the other end of the rod member 40 is connected to a manual or automatic controller. In this article, the manual controller can be an operator, and the automatic controller can be an adjustable servo motor. The rod member 40 moves back and forth along its connection axis on the disk member 10, thereby changing the angle of the disk member 10 and adjusting the amplitude of the motion ([ Figure 2 , Figure 3 ) that is desired to be generated on the output shaft 50 of the disk member 10 and the shaft member 20. More specifically, the rod member 40 adjusts the amplitude of the motion transmitted to the above-mentioned output shaft 50 and changes the angle of the above-mentioned disk member 10 by moving back and forth along its connection axis on the disk member 10.

[0053] The above-mentioned output shaft 50 is the unit to which the motion finally transmitted after being adjusted / controlled in terms of amplitude, frequency, and harmonic waves is transmitted. In a preferred embodiment of the present invention, the output shaft 50 is a shaft rod that can be modified according to preferences and needs.

[0054] The above-mentioned motion transmission component H linearly transmits the power generated by the rotational motion of the above-mentioned shaft member 20 to the output shaft 50. In a preferred embodiment of the present invention, the motion transmission component H includes at least two spherical joints k and at least one piston assembly p. Different materials can be selected here according to specific requirements and preferences, and its main purpose is to linearly transmit the motion generated by the disk member 10 and the shaft member 20 to the output end. The above-mentioned spherical joint k can receive any form of motion generated by the movement of the shaft member 20 on the surface 10.1 without interfering with it, and then transmit the motion to the piston assembly p. Preferably, two spherical joints k are used in the invention, but the number of spherical joints can be adjusted according to preferences and requirements. In another embodiment of the present invention, different fittings are used to replace the spherical joint k. The above-mentioned piston assembly p is composed of a piston and a cylinder for the piston to reciprocate. The piston assembly p transmits the motion received from the spherical joint k to the output shaft 50.

[0055] The above-mentioned drive component T is a structure capable of generating rotational motion. In a preferred embodiment of the present invention, the drive component T is composed of a motor and a belt. In other embodiments of the present invention, the drive component T can be any device capable of generating rotational motion. The above-mentioned drive component T is connected to the above-mentioned shaft member 20 through a drive shaft 30.

[0056] The working principle of the present invention will be explained below.

[0057] The above-mentioned shaft member 20 receives the rotational motion generated by the drive component T from the above-mentioned drive shaft 30. In other words, the drive shaft 30 transmits the rotational motion it receives from the drive component T to the shaft member 20. The shaft member 20 starts to perform rotational motion under the action of the received rotational motion. The shaft member 20 performs rotational motion along a specific trajectory on the surface 10.1 ( Figure 4 ). When the shaft member 20 moves along the above-mentioned trajectory on the surface 10.1, harmonic motion will be generated according to the structure of the surface 10.1. The spherical joint k connected to the shaft member 20 can receive any generated harmonic motion without interference and transmit it to the piston assembly p. Under the action of the motion transmitted by the spherical joint k, the piston assembly p starts to perform compression and relaxation motions along a specific axis and transmits this motion to the output shaft 50 in a reciprocating motion along the same axis.
