Description

Technical Field

[0001] This utility model relates to the field of metal sphere material production equipment and production technology, and in particular to a sphere material screening device. Background Technology

[0002] Currently, metal spheres are widely used in various industries. However, existing technologies often require manual sorting of spheres of different sizes, which is time-consuming and labor-intensive, thus increasing production costs. Therefore, the low level of automation in sphere sorting is a major problem for metal sphere manufacturers.

[0003] There is an urgent need for a high-performance spherical material screening device specifically designed for metallic spherical materials. Utility Model Content

[0004] This utility model provides a spherical material screening device, which is arranged at the discharge port of a production machine; its key technical feature is that the main body of the spherical material screening device includes a screen 1 and a main support 8; wherein:

[0005] The main body of the spherical material screening device is a trough-shaped structure;

[0006] The screen 1 is arranged at the bottom of the main support 8. The main support 8 with side plates on both sides and the screen 1 together form a groove-shaped structure with an upper opening that allows materials to pass through.

[0007] The sieve holes in sieve 1 are one of the following shapes or a combination thereof: circular, elliptical, or regular polygonal; the diameter of the inscribed circle of the sieve holes in sieve 1 is 1 to 50 mm.

[0008] The preferred technical content of the spherical material screening device of this utility model is as follows: the spherical material screening device is further provided with a metal cover plate 2 for shielding, which is arranged above the main body of the spherical material screening device, which is composed of a screen 1 and a main support 8 in a trough-shaped structure; after adding the metal cover plate 2, the screen 1 is arranged at the bottom of the main support 8, and the main support 8 with side plates on both sides and the screen 1 together form a closed pipe that allows materials to pass through;

[0009] The sieve openings in sieve 1 are elliptical with a major axis to minor axis ratio of 1.35 to 1.83; the diameter of the inscribed circle of the sieve opening is 5 to 32 mm. This is the optimal structural feature obtained through extensive experiments combined with the angle between the plane containing sieve 1 and the horizontal plane.

[0010] The metal cover plate 2 is connected to the main bracket 8 as a whole through the connecting hole;

[0011] The connecting hole set on the metal cover plate 2 is a cross-shaped baffle hole 4; the baffle hole 4 is set on the side plate; the horizontal and vertical lengths of the cross-shaped hole in the cross-shaped baffle hole 4 are 3.5 to 7.2 times the width; this is a preferred technical feature with good technical effect obtained through a large number of experiments combined with technical requirements.

[0012] The connection holes provided on the main bracket 8 are one of the following three types or a combination thereof: arc-shaped hole 6 on the main bracket, circular hole 7 on the main bracket, and vertical hole 9 on the main bracket;

[0013] The connection holes on the main bracket 8 are located on the side plate of the main bracket 8.

[0014] The angle between the plane containing screen 1 and the horizontal plane is 10° to 80°. More preferably, the angle between the plane containing screen 1 and the horizontal plane is 13° to 55°. Combined with the aforementioned "the screen holes in screen 1 are elliptical with a major axis to minor axis ratio of 1.35 to 1.83," and "the horizontal and vertical lengths of the '+' shaped holes in the '+' shaped baffle holes 4 are 3.5 to 7.2 times their width," a superior technical effect can be achieved.

[0015] The inscribed circle diameter of the sieve holes in sieve 1 is 3-10mm or 15-30mm. This parameter setting is made to meet the screening requirements of related products in common scenarios, accommodating two different typical application scenarios.

[0016] The spherical material screening device is also equipped with an automatic counter 3; the automatic counter 3 is connected to the metal cover plate 2 to realize the automatic counting of spherical particles.

[0017] The main support is fixed to the production machine through the main support circular holes and the main support arc-shaped holes. It is easy to install and the slope can be adjusted so that metal spheres of different weights and materials can slide down without obstacles by their own weight.

[0018] In this invention, the sieve holes on the screen are determined according to the size of the material to be screened, and the diameter of the sieve holes can be adjusted within a certain range as needed.

[0019] The spherical material screening device of this utility model is simple to install. It can be fixed to the discharge port of the metal spherical material production machine by screws through the arc-shaped hole 6 and the circular hole 7 of the main support. The arc-shaped hole 6 of the main support allows for adjustment of the installation angle between the base plate of the main support 8, i.e., the screen 1, and the horizontal plane (see installation diagram). Figure 2 This design allows spheres of different masses and materials to roll smoothly downwards under their own weight.

[0020] The aperture of the screen 1 can be determined according to the size of the metal balls produced. Those smaller than the required size will fall through the screen, while those larger than the required size will continue to roll down in the groove through the inner cavity of the groove. The metal cover plate 2 is fixed to the main support 8 by connecting the baffle hole 4 and the vertical hole 9 of the main support with screws. It can slide and adjust on the main support 8 to control the maximum size of the screened metal balls.

[0021] The spherical material with the correct size passes through the metal cover plate 2 and rolls down from the top. When it passes through the automatic counter 3, the spherical particles that have not been screened out can be automatically counted.

[0022] The spherical material screening device of this utility model is installed at the discharge port of the spherical material production equipment. It is easy to install, the slope is adjustable, and it can automatically count the spherical particles that are not screened out after sorting.

[0023] The main support is fixed to the production machine through the main support circular holes and the main support arc-shaped holes. It is easy to install and the slope can be adjusted so that metal spheres of different weights and materials can slide down without obstacles by their own weight.

[0024] The spherical material screening device is also equipped with a metal cover plate 2, which is arranged at the bottom of the screen 1 to block large spherical materials. The aperture of the screen 1 can be set according to the size of the produced spheres. Those smaller than the required size will pass through the screen 1, while those larger than the required size will be blocked by the metal cover plate 2. The metal cover plate 2 is fixed to the vertical hole 9 of the main support of the main support 8 through the baffle hole 4, and can be adjusted up and down according to the size of the spheres to be screened.

[0025] The metal cover plate is fixed to the vertical hole 9 of the main support through the hole 4, which can be adjusted up and down. The circular hole 7 and the arc hole 6 of the main support can fix the sorting device, i.e. the main support 8, at the discharge port of the spherical material production equipment. The slope can be adjusted through the arc hole 6 so that the material falls by its own weight.

[0026] Materials that fall through the screen and materials blocked by the metal cover are both dimensionally non-compliant and should be placed in the non-compliant material bin; materials that fall through the metal cover are compliant and should be placed in the compliant material bin.

[0027] The slope adjustment allows the spheres to slide down unimpeded by gravity. The screen 1 is connected to the top of the main support 8, and the aperture can be determined according to the diameter of the material to be screened. The spheres slide over the screen 1, and those smaller than the required aperture fall through the gaps in the screen 1 to achieve screening. The metal cover 2 is connected to the middle of the main support 8 through holes 4 and 9, and its height can be adjusted to block spheres larger than the required diameter, thus achieving sorting. The spheres that meet the diameter requirements will slide over the metal cover 2, and the automatic counter 3 will count automatically.

[0028] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The embodiments of this application described above do not constitute a limitation on the scope of protection of this application.

[0029] The top of the main support 8 is the ball-collecting end. By adjusting the slope, the ball falls automatically under gravity. The screen 1, connected to the main support 8, consists of multiple perforated plates. The preferred aperture range of the perforated plates is as described above and can be determined based on the diameter of the material to be screened. A metal cover plate 2 is located in the middle of the main support 8, and the metal cover plate 2 is connected to an automatic counter 3, enabling automatic counting during sorting. The above-mentioned device enables the sorting of spherical materials, solving the problem of low automation in spherical sorting.

[0030] This utility model has a simple structure, is highly operable, is applicable to various typical application scenarios, and has excellent overall technical effects. Attached Figure Description
