Description

Technical Field

[0001] This utility model belongs to the field of product screening technology, and specifically relates to a microsphere sphericity screening device for screening microspheres such as submillimeter-sized alumina, zirconium oxide, plastic balls, and metal balls that require good sphericity. Background Technology

[0002] Ceramic microspheres typically refer to ceramic spheres or spheroids made primarily of inorganic silicates through various specialized processing methods, with diameters generally in the sub-millimeter or millimeter range. During the production of ceramic microspheres, irregularly shaped spheres and those with good sphericity may become mixed together. Furthermore, during use, irregularly shaped spheres have uneven surfaces, lack good flowability, increase self-wear, and can introduce abrasive material into the raw materials, contaminating them and causing wear on equipment over time. Because ceramic microspheres are extremely small, their shape differences are impossible to distinguish with the naked eye. Moreover, when screening large quantities, manual screening is even more difficult to accurately differentiate between irregularly shaped and well-spherical microspheres. Most screening equipment on the market lacks sphericity screening capabilities. Therefore, there is an urgent need for a highly efficient device for screening ceramic microspheres with good sphericity and smooth surfaces. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a microsphere sphericity screening device with simple structure, reasonable design and easy production. Through the coordinated action of the reciprocating drive mechanism and the first transmission bearing, the material tray is driven to tilt left and right. The microspheres roll down the guide groove to the designated position and are collected, which can quickly screen the microspheres.

[0004] Technical solution: In order to achieve the above objectives, this utility model provides a microsphere sphericity screening device, including: a base, on which a mounting frame is provided; A material tray is provided above the mounting frame and connected via a first transmission bearing; and the material tray is provided with at least one guide groove. A reciprocating drive mechanism is located on one side of the base, and its output end cooperates with the material collection tray. The microsphere sphericity screening device of this invention, through the coordinated action of the reciprocating drive mechanism and the first transmission bearing, drives the material collection tray to tilt left and right. The microspheres roll down the guide groove to a designated position and are collected, enabling rapid screening of microspheres, removing products that do not meet the requirements, and reducing the impact of irregularly shaped balls.

[0005] Preferably, a baffle is provided on the outer side of the material tray. The baffle can prevent the product from falling from the side and provides good protection for it.

[0006] Preferably, the upper surface of the material tray is curved with an opening angle of 60°; the guide groove is located on the curved surface and is inclined. The curved surface allows the product to roll on it, facilitating product screening.

[0007] More preferably, the guide groove is provided with a guide member, which is inclined within the guide groove. The inclined guide member facilitates guiding the product to the receiving position.

[0008] The reciprocating drive mechanism includes a reciprocating drive assembly. The output end of the reciprocating drive assembly is provided with a second transmission bearing. The second transmission bearing is located below the material tray. The reciprocating drive assembly drives the second transmission bearing to work in coordination with the first transmission bearing, thereby causing the material tray to perform an operational tilting motion.

[0009] Preferably, the reciprocating drive assembly includes a drive unit, an eccentric drive disk, a crank, and a linkage assembly. The drive unit is mounted on a base, and its output end is provided with an eccentric drive disk. The drive shaft of the eccentric drive disk on the side away from the drive unit is connected to the crank. One end of the crank is connected to the linkage assembly, and the end of the linkage assembly away from the crank is provided with a transmission assembly for driving the movement of the material tray. The transmission assembly is located below the material tray, and the two cooperate with each other.

[0010] More preferably, the coefficient of friction of the upper surface of the material tray is between 0.2 and 0.4.

[0011] More preferably, the slope of the guide groove and guide member is 5~15°, which facilitates the product falling into the collection tray.

[0012] In addition, the base includes an L-shaped support, the mounting bracket is mounted on the L-shaped support, and the reciprocating drive mechanism is mounted on the L-shaped support.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The microsphere sphericity screening device of this utility model, through the coordinated action of the reciprocating drive mechanism and the first transmission bearing, drives the material tray to tilt left and right. The microspheres roll down the guide groove to the designated position and are collected. It can quickly screen the microspheres, remove products that do not meet the requirements, and reduce the impact of irregularly shaped balls.

[0014] 2. The application of this device can significantly reduce the time required for manual screening, resulting in substantial cost savings. More importantly, while optimizing costs, it can ensure that the proportion of ceramic microspheres with excellent sphericity remains stable at over 98%, fully meeting the equipment's usage requirements.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] like Figure 1 A microsphere sphericity screening device is shown, comprising: a base 1, on which a mounting frame 11 is provided; The material tray 2 is located above the mounting bracket 11 and is connected via the first transmission bearing 3; and the material tray 2 is provided with at least one guide groove 21. The reciprocating drive mechanism 4 is located on one side of the base 1, and its output end is engaged with the material tray 2.

[0019] In the preferred embodiment of this invention, a baffle 201 is provided on the outer side of the material tray 2.

[0020] The upper surface of the material tray 2 is curved with an opening angle of 60°; the guide groove 21 is located on the curved surface and is inclined. It should be noted that the opening angle is the angle formed by the intersection of the extended lines at both ends of the curved surface. In this embodiment, a 60° angle is preferred to ensure that spherical materials with good sphericity can roll naturally when the reciprocating motion machine is not activated. It is conceivable that the opening angle can be adjusted according to actual needs.

[0021] like Figure 3 The guide groove 21 shown is provided with a guide member 22, which is inclined in the guide groove.

[0022] like Figure 1 , Figure 2The reciprocating drive mechanism 4 shown includes a reciprocating drive assembly 41. The output end of the reciprocating drive assembly 41 is provided with a second transmission bearing 42. The second transmission bearing 42 is located below the material tray 2. The reciprocating drive assembly 41 drives the second transmission bearing 42 to work together with the first transmission bearing 3 to drive the material tray 2 to perform a tilting operation.

[0023] like Figure 2 The reciprocating drive assembly 41 shown includes a drive unit 411, an eccentric drive disk 412, a crank 413, and a linkage assembly 414. The drive unit 411 is mounted on the base 1, and its output end is provided with an eccentric drive disk 412. The drive shaft of the eccentric drive disk 412 on the side away from the drive unit 411 is connected to the crank 413. One end of the crank 413 is connected to the linkage assembly 414, and the end of the linkage assembly 414 away from the crank 413 is provided with a transmission assembly 415 for driving the movement of the material tray 2. The transmission assembly 415 is located below the material tray 2, and the two cooperate with each other.

[0024] like Figure 3 The slope of the guide groove 21 and guide element 22 shown is between 5° and 15°. Microspheres with good sphericity can fall from the curved guide groove into the collection tray below. The slope can be adjusted according to actual needs.

[0025] The coefficient of friction on the upper surface of the material tray 2 is between 0.2 and 0.4. This invention utilizes the difference in friction between different ceramic microspheres as an effective method to distinguish irregularly shaped spheres from highly spherical ceramic microspheres. It should be noted that a material tray with a suitable coefficient of friction can be selected according to actual needs, as long as it meets the screening requirements.

[0026] The base 1 includes an L-shaped support 101, the mounting bracket 11 is disposed on the L-shaped support 101, and the reciprocating drive mechanism 4 is mounted on the L-shaped support 101.

[0027] The working principle of the microsphere sphericity screening device described in this embodiment is as follows: First, place the microspheres to be screened in the material tray 2; Start the reciprocating motion machine 4. Through the coordinated operation of the second transmission bearing 42 and the first transmission bearing 3, the material tray 2 is driven to tilt left and right. During this process, the microballs roll down along the guide 21 and are collected in the collection tray below. After running for about 5 minutes, when there are no small balls rolling normally on the curved surface, turn off the equipment switch and stop running. To ensure the screening effect, the collected microspheres need to be screened repeatedly 2-3 times.

[0028] During the initial screening, the drive tilt angle is set to 15°, and subsequent screening angles are adjusted to 10°, 5°, and so on. This gradual, multi-stage screening process maximizes the acquisition of microspheres with superior sphericity.

[0029] The screening principle of this device is based on the difference in friction between irregularly shaped balls and well-shaped balls as they roll down an inclined plane. When both types of balls are placed on the same plane and at the same angle on an inclined plane, the irregularly shaped balls take longer to roll down than the well-shaped balls. Therefore, based on this phenomenon, a ceramic microsphere sphericity screening device was designed. This device uses a swinging method to change the inclination angle of the inclined plane, causing the microspheres to roll back and forth for collection, thus achieving the separation and screening of irregularly shaped balls and well-shaped balls. This equipment can screen and collect over 98% of the well-shaped balls.

[0030] Furthermore, multiple screenings can be conducted to obtain microspheres with superior sphericity to the greatest extent possible.

[0031] It should be noted that this device can not only screen ceramic microspheres, but also other similar products, such as submillimeter-sized alumina, zirconium oxide, plastic balls, metal balls, etc., which require microspheres with good sphericity for screening.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
