Description

Technical Field

[0001] This utility model is a raw material screening device for quartz stone processing, belonging to the field of quartz stone processing technology. Background Technology

[0002] Quartz stone, as we usually refer to it, is a new type of artificial stone made of more than 90% quartz crystals, plus resin and other trace elements. It is a large-format slab made by pressing it under certain physical and chemical conditions using special machines. Its main material is quartz, a mineral that easily turns into a liquid state when heated or under pressure, and it is also a fairly common rock-forming mineral.

[0003] Chinese patent CN219648071U proposes a permanent magnet synchronous motor that facilitates end cap installation. It features a first and second screening plate inside the housing. A motor and eccentric wheel drive the first and second screening plates to reciprocate, facilitating the screening of quartz stone materials. By using the different apertures of the first and second screening plates, two specifications of quartz stone can be screened simultaneously. However, this design places the first and second screening plates side-by-side, requiring a relatively long screening path to ensure screening quality. This side-by-side design occupies considerable space and has low practicality. There is an urgent need for a raw material screening device for quartz stone processing to address these issues.

This design solves the problem that the original raw material screening device for quartz stone processing occupies a large space and has poor screening quality.

[0024] In this embodiment, countersunk holes 51 are provided on both the left and right ends of the first vibrating outer frame 5. Fixing bolts are installed inside the countersunk holes 51. The first vibrating outer frame 5 is fixedly connected to the inner wall of the screening cabinet 1 via these fixing bolts. This design facilitates the installation and fixation of the first vibrating outer frame 5. The first vibrating outer frame 5 is tilted to the left, allowing it to vibrate together with the first screen 54 inside it when vibrating. Simultaneously, objects on the upper surface of the first screen 54 roll to the left during vibration. The upper end of the first vibrating outer frame 5 is equipped with... A first vibrating bridge 52 is provided, and a first vibrating motor 53 is mounted on the upper surface of the first vibrating bridge 52. The first vibrating motor 53 can drive the first vibrating outer frame 5 to vibrate through the first vibrating bridge 52. A first mounting bracket 55 is provided on the inner side of the first vibrating outer frame 5. A first through groove 56 is opened on the left side of the first mounting bracket 55. Objects on the upper surface of the first screen 54 can fall down through the first through groove 56. The first screen 54 is provided on the inner side of the first vibrating outer frame 5 and abuts against the first mounting bracket 55. A limiting slot 58 is provided on the front end face, and a limiting block 57 is engaged inside the limiting slot 58. The upper end face of the first screen 54 abuts against the lower end face of the limiting block 57. The first mounting bracket 55 facilitates the fixed placement of the first screen 54. The design of the limiting block 57 facilitates the limiting of the first screen 54, thereby preventing the first screen 54 from detaching during vibration. A first opening 31 is provided on the right end face of the screening cabinet 1. A first guide plate 32 is provided inside the first opening 31. The first guide plate 32 is inclined towards the first collection box 3. The discharge plate 6 is fixedly connected to the first vibrating outer frame 5 by the first connecting plate 61. The first discharge plate 6 is inclined towards the first opening 31. The object that is screened by the first screen 54 will fall on the upper surface of the first discharge plate 6. The first discharge plate 6 vibrates with the vibration of the first vibrating outer frame 5 and guides the object on its surface toward the first opening 31 and the first guide plate 32 until it enters the first collection box 3. The design of the first connecting plate 61 can prevent the screened material from falling from both sides of the first discharge plate 6.

[0025] In this embodiment, the second vibrating outer frame 7 is tilted to the right. The second vibrating outer frame 7 can drive the second screen 73 inside it to vibrate synchronously, causing objects on the surface of the second screen 73 to roll to the right with the vibration. A second vibration bridge 71 is installed on the upper end face of the second vibrating outer frame 7, and a second vibration motor 72 is installed on the upper end face of the second vibration bridge 71. The second vibration motor can drive the second vibrating outer frame 7 to vibrate through the second vibration bridge 71. A second mounting bracket 74 is provided on the inner side of the second vibrating outer frame 7. A second through groove 75 is opened on the right side of the second mounting bracket 74. Objects on the upper surface of the second screen 73 can fall down through the second through groove 75. A second screen 73 is provided on the inner side of the second vibrating outer frame 7. The second screen 73 abuts against the second mounting bracket 74. The second screen 73 can perform a second screening of objects. A second opening 41 is opened on the left end face of the screening cabinet 1. A second guide plate 42 is provided inside the second opening 41. The second guide plate 42 is tilted towards the second collection box 4. The second discharge plate 8 is fixedly connected to the second vibrating outer frame 7 via the second connecting plate 81. The second discharge plate 8 is inclined toward the second opening 41. The object screened by the second screen 73 will fall onto the upper surface of the second discharge plate 8. The second discharge plate 8 vibrates with the vibration of the second vibrating outer frame 7 and guides the object on its surface toward the second opening 41 and the second guide plate 42 until it enters the second collection box 4. The design of the second connecting plate 81 can prevent the screened material from falling from both sides of the second discharge plate 8. The waste collection box 9 is equipped with a ramp 91 inside. The ramp 91 is inclined to the left. The design of the ramp 91 can prevent waste from always accumulating directly below the second channel 75. The front end of the screening cabinet 1 is rotatably connected to the cabinet door 11 via a hinge. The outside of the raw material inlet 2 is equipped with a reinforcing rib 21 connected to the outer surface of the screening cabinet 1. The reinforcing rib 21 can strengthen the load-bearing structure of the raw material inlet 2. The cabinet door 11 makes it easy for users to replace the first screen 54 and the second screen 73 of different specifications.

[0026] Working Principle: By selecting appropriate first screen 54 and second screen 73, the user can obtain two specifications of materials simultaneously in one screening operation. For example, when the user needs materials with a radius of 0-3mm and materials with a radius of 3-6mm, the user places the 3mm aperture screen at the position of the first screen 54 and the 6mm aperture screen at the position of the second screen 73. Then, the first vibration motor 53 and the second vibration motor are started, and the material to be screened is fed into the screening cabinet 1 through the raw material inlet 2. The material falls onto the upper surface of the first screen 54 first. The first vibration motor 53 drives the first vibration frame 5 to vibrate through the first vibration bridge 52. The first vibration frame 5 drives the first screen 54 to vibrate together. The vibration of the first screen 54 can screen the material on its upper surface. Materials with a size smaller than 3mm fall onto the first discharge plate through the holes of the first screen 54. On the upper surface of the first discharge plate 6, the first discharge plate 6 guides materials smaller than 3mm to the right as it vibrates, and they fall into the first collection box 3 through the first guide plate 32. Materials larger than 3mm will roll to the left as the first screen 54 vibrates, and fall down through the first channel 56 until they land on the upper surface of the second screen 73. The second vibration motor 72 drives the second vibration frame 7 to vibrate through the second vibration bridge 71. The second vibration frame 7 drives the second screen 73 to vibrate together, thereby screening the materials on the upper surface of the second screen 73. Materials smaller than 6mm and larger than 3mm fall onto the upper surface of the second discharge plate 8 through the holes of the second screen 73 and are eventually collected in the second collection box 4. Materials larger than 6mm roll to the right as the second screen 73 vibrates, and fall down through the second channel 75 into the waste collection box 9, waiting to be recycled and crushed again.

[0027] It should be noted that this design is not limited to the first screen 54 and the second screen 73. A third and fourth screen can be added vertically according to actual needs, so as to screen out more specifications of materials at the same time. For example, in a certain production, four specifications of raw materials of 2mm, 4mm, 6mm and 8mm are required at the same time. Moreover, this design only occupies vertical space and has strong adaptability and practicality.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
