The first rubber pad, the second rubber pad, the third rubber pad, and the fourth rubber pad are respectively disposed on the four sides of the vibrating plate along the preset trajectory and each includes a plurality of rubber columns. The number of splicing rubber pads is four, and the four splicing rubber pads are respectively disposed at the four corners of the vibrating plate and respectively connected to the corresponding first rubber pad, the second rubber pad, the third rubber pad, and the fourth rubber pad. Each splicing rubber pad includes a plurality of sub-rubber pads, and each sub-rubber pad includes a plurality of rubber columns. The rubber columns of each sub-rubber pad are inclined at a certain angle toward the preset trajectory.

[0011] In some embodiments, the vibratory feeder includes a base and a fence. One side of the base is connected to the vibration mechanism, and the fence is connected to the edge of the other side of the base. The other side of the base carries multiple materials. The rubber pad assembly is disposed on the base and contacts the fence. The guide rail assembly and the screening assembly are both disposed on the fence, and the discharge port is disposed on the fence.

[0012] In some embodiments, the screening assembly includes a first guide member disposed on the vibrating plate and above the guide rail assembly, wherein the side of the first guide member facing the material feeding direction is configured as a guide slope.

[0013] In some embodiments, the screening assembly further includes a second guide member, which includes a connecting plate, a limiting plate, and a guide portion. The connecting plate is connected to the vibrating plate and located above the guide rail assembly. The first guide member and the connecting plate are spaced apart along the material movement direction. One end of the limiting plate is connected to the connecting plate, and the other end of the limiting plate extends to one side of the guide rail assembly. The guide portion is connected to the side of the limiting plate facing the first guide member, and the guide portion guides the material.

[0014] In some embodiments, the screening assembly further includes a detector and an air blowing element. The detector is disposed on the vibrating plate and above the guide rail assembly, and the first guide element and the detector are spaced apart along the material movement direction. The air blowing element is disposed on the vibrating plate and between the detector and the guide rail assembly. The detector detects the material on the guide rail assembly, and the air blowing element blows away the material that does not meet the requirements detected by the detector.

[0015] In some embodiments, the guide rail assembly includes a guide rail and an elastic rubber element. The guide rail is disposed on the vibrating plate and located between the rubber pad assembly and the screening assembly. The side of the guide rail facing the screening assembly is configured as a conveying slope. The elastic rubber element is disposed on the conveying slope. One end of the elastic rubber element receives the material conveyed along the preset trajectory, and the other end of the elastic rubber element extends to the discharge port.

[0018] In some embodiments, the vibration mechanism further includes a damping element disposed on the side of the base opposite to the vibrating disc.

[0019] In actual use, the above-mentioned vibrating screening device pours multiple materials into the vibrating plate. The vibration mechanism drives the vibrating plate, rubber pad assembly, guide rail assembly, and screening assembly to vibrate. The vibrating plate vibrates the multiple materials onto the rubber pad assembly. Since the rubber columns of the rubber pad assembly are inclined towards a preset trajectory, when the rubber pad assembly and the vibrating plate vibrate together, the materials on the rubber pad assembly will move in the direction of the rubber column inclination, i.e., the preset trajectory. Thus, multiple materials are conveyed along the preset trajectory under the vibration of the multiple rubber columns of the rubber pad assembly. While the materials are conveyed under the vibration of the vibrating plate and the rubber pad assembly, one end of the guide rail assembly receives the materials conveyed along the preset trajectory and conveys the materials to the discharge port according to preset requirements. During the process of conveying materials by the guide rail assembly, the screening assembly will also screen out the materials conveyed by the guide rail assembly that do not meet the preset requirements. The screened materials fall onto the rubber pad assembly and are conveyed again along the preset trajectory under the vibration of the rubber pad assembly, thereby realizing the automated screening of materials.

[0020] The vibrating screening device provided in this application embodiment, through the coordinated operation of the vibrating plate, rubber pad assembly, vibration mechanism, guide rail assembly, and screening assembly, enables materials to be conveyed out according to preset requirements, realizing automated material screening, improving screening efficiency, reducing labor costs, and minimizing material collisions and scratches. Furthermore, when the shape and size of the material to be screened changes, the distance between the screening assembly and the guide rail assembly can be adjusted to accommodate materials of different shapes and sizes; when the external equipment corresponding to the discharge port is switched, the position of the rubber pad assembly can be changed to alter the preset trajectory, thus making it suitable for different external equipment, demonstrating high versatility of the vibrating screening device.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0070] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0071] See Figure 1 This application provides a vibrating screening device 100. The vibrating screening device 100 screens multiple materials 200 by vibration, causing the materials 200 to be conveyed out according to preset requirements. In this embodiment, the material 200 can be a U-shaped frame, and the preset requirements can be understood as the U-shaped frame being conveyed out in a "lying down" position, with the opening of the U-shaped frame facing either side. It is understood that in other embodiments, the material 200 can also be small items such as screws or metal washers.

[0072] Please refer to the above. Figure 1 and Figure 2The vibrating screening device 100 includes a vibrating disc 10, a rubber pad assembly 20, a vibration mechanism 30, a guide rail assembly 40, and a screening assembly 50. The vibrating disc 10 is connected to and located above the vibration mechanism 30. The rubber pad assembly 20 is disposed inside the vibrating disc 10. The guide rail assembly 40 is disposed inside the vibrating disc 10 and located above the rubber pad assembly 20. The screening assembly 50 is disposed inside the vibrating disc 10 and located above the guide rail assembly 40. The vibration mechanism 30 drives the vibrating disc 10, the rubber pad assembly 20, the guide rail assembly 40, and the screening assembly 50 to vibrate together. The vibrating disc 10 vibrates the material 200 onto the rubber pad assembly 20, and the rubber pad assembly 20 vibrates the material onto the guide rail assembly 40. The guide rail assembly 40 vibrates the material 200 to be conveyed out according to preset requirements. The screening assembly 50 filters out the material 200 that does not meet the preset requirements conveyed by the guide rail assembly 40.

[0073] The vibrating plate 10 carries multiple materials 200 and has a discharge port 122. In this embodiment, the vibrating plate 10 includes a base 11 connected to the vibration mechanism 30 on one side and carrying multiple materials 200 on the other side, and a fence 12 connected to the edge of the other side of the base 11. The fence 12 can be a rounded rectangular structure. The rubber pad assembly 20 is disposed on the base 11 and contacts the fence 12. The guide rail assembly 40 and the screening assembly 50 are both disposed on the inner side of the fence 12, and the discharge port 122 is disposed on the fence 12. In this embodiment, the vibrating plate 10 also includes a conveying plate 13, which is connected to the outer side of the fence 12 and corresponds to the discharge port 122. The conveying plate 13 has a groove structure adapted to the materials 200 and communicating with the discharge port 122. The conveying plate 13 can also be connected to external equipment so that the vibrating screening device 100 can directly supply the screened materials 200 to the external equipment. In actual use, the vibratory feeder 10 pours multiple materials 200 onto the base 11. Under the vibration of the vibration mechanism 30, the multiple materials 200 vibrate from the base 11 onto the rubber pad assembly 20. Under the vibration of the rubber pad assembly 20, the multiple materials 200 are conveyed to the guide rail assembly 40. With the coordinated cooperation of the guide rail assembly 40 and the screening assembly 50, the multiple materials 200 are output from the discharge port 122 onto the conveying plate 13. The screened multiple materials 200 are then supplied to external equipment via the conveying plate 13.

[0074] Please refer to the above. Figures 3 to 6The rubber pad assembly 20 is disposed on the base 11 of the vibrating plate 10 along a preset trajectory S. The rubber pad assembly 20 includes a plurality of rubber columns 21, each of which is elastic. The rubber columns 21 are inclined at a certain angle toward the preset trajectory S. In this embodiment, the inclination angle of the rubber columns 21 can be in the range of 5° to 15°, for example, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc., preferably 10°. The preset trajectory S is approximately a rounded rectangle and the starting point and ending point of the preset trajectory S do not coincide so that the preset trajectory S is approximately spiral-shaped. The rubber pad assembly 20 is also approximately a rounded rectangle and is disposed on the edge of the base 11. In actual use, when multiple materials 200 vibrate from the base 11 onto the rubber pad assembly 20, multiple rubber columns 21 support the materials 200 together. As the rubber pad assembly 20 vibrates, the materials 200 move in the direction of the tilt of the rubber columns 21. The faster the vibration frequency of the vibration mechanism 30, the faster the materials 200 move. Conversely, the slower the vibration frequency of the vibration mechanism 30, the slower the materials 200 move.

[0075] In this embodiment, the rubber pad assembly 20 includes a first rubber pad 22, a second rubber pad 23, a third rubber pad 24, a fourth rubber pad 25, and a splicing rubber pad 26, which are respectively disposed on the base 11 of the vibrating plate 10 along a preset trajectory S. Each of the first rubber pad 22, second rubber pad 23, third rubber pad 24, fourth rubber pad 25, and splicing rubber pad 26 has multiple rubber columns 21 that are inclined at a certain angle towards the preset trajectory S. The first rubber pad 22, second rubber pad 23, third rubber pad 24, and fourth rubber pad 25 are all approximately rectangular and can all be elastic rubber pads. Rubber pads 22, 23, 24, and 25 are respectively disposed on the four sides of the base 11 and are in contact with the fence 12. There are four splicing rubber pads 26, which are respectively disposed at the four corners of the base 11 of the vibrating plate 10, and the four splicing rubber pads 26 are respectively connected to the first rubber pad 22, the second rubber pad 23, the third rubber pad 24, and the fourth rubber pad 25. The shape of each splicing rubber pad 26 can be adapted to the corners enclosed by the base 11 and the fence 12, such as a square or a fan shape. Each splicing pad 26 may include multiple sub-pads 262, meaning each splicing pad 26 can be understood as being composed of multiple sub-pads 262. The adhesive posts 21 of each sub-pad 262 are inclined at a certain angle towards a preset trajectory S. The preset trajectory S is linear at the first pad 22, second pad 23, third pad 24, and fourth pad 25, with the inclination directions of the multiple adhesive posts 21 corresponding to these pads aligned. However, the trajectory S at the splicing pad 26 is arc-shaped, with the inclination directions of the multiple adhesive posts 21 corresponding to the sub-pads 262 not aligned and requiring adaptive inclination according to the preset trajectory S. In this embodiment, each splicing pad 26 includes five sub-pads 262. In other embodiments, each splicing pad 26 may include more or fewer sub-pads 262, depending on the specific circumstances.

[0076] The vibration mechanism 30 is connected to the base 11 of the vibrating plate 10 and drives the vibrating plate 10, the rubber pad assembly 20, the guide rail assembly 40, and the screening assembly 50 to vibrate together, causing multiple materials 200 to vibrate from the vibrating plate 10 to the rubber pad assembly 20, and then conveyed along a preset trajectory S to the guide rail assembly 40 under the vibration conveying of multiple rubber columns 21 in the rubber pad assembly 20. In this embodiment, the vibration mechanism 30 includes a base 31, a vibrator 32, a fixed column 33, and an elastic component 34. The base 31 is disposed below the vibrating plate 10. The vibrator 32 can be an electromagnet. The vibrator 32 is disposed on the base 31 and connected to the base 11 of the vibrating plate 10. The fixed column 33 is disposed on the base 31 and spaced apart from the vibrator 32. The elastic component 34 is supported on the fixed column 33 and has elasticity. The vibration mechanism 30 also includes four connecting columns 35, through which the vibrator 32 is fixedly connected to the base 31. Thus, in actual use, the external power supply (not shown) generates pulse current at a preset frequency and transmits it to the vibrator 32. The vibrator 32 generates magnetic force to attract the base 11 to move downward, and moves the vibrating plate 10 downward. The vibrating plate 10 moves downward and causes the elastic component 34 to deform with the fixed column 33 as the support point. When the vibrator 32 loses power, the elastic component 34 elastically recovers with the fixed column 33 as the support point to drive the base 11 to move upward, causing the vibrating plate 10 to move upward, thereby causing the vibrating plate 10 to vibrate. By providing the vibrator 32 with pulse current of different frequencies, the vibrator 32 can provide vibration sources of different frequencies, thus adapting to different vibration requirements and improving the versatility of the screening vibration device.

[0077] In this embodiment, there are four fixing posts 33. The four fixing posts 33 are arranged on the four sides of the base 31, and each fixing post 33 is arranged in the middle of the corresponding side. The elastic component 34 includes four spring plate units 342 and four connecting blocks 344. The middle part of the four spring plate units 342 is connected to the four fixing posts 33 respectively. Each spring plate unit 342 undergoes elastic deformation with the corresponding fixing post 33 as the support point. Each connecting block 344 is connected between two spring plate units 342. The spring plate unit 342 can be composed of one, two, three or more layers of fiberglass spring plate spacers. In this embodiment, the four spring plate units 342 include two long spring plate units 342 and two short spring plate units 342. Each long spring plate unit 342 is composed of three layers of fiberglass spring plate spacers, and each short spring plate unit 342 is composed of two layers of fiberglass spring plate spacers. Thus, by setting the specific structure of the elastic component 34, the vibrator 32 drives the base 11, the base 11 then drives the four spring plate units 342, and the four spring plate units 342 then drive the base 11 through elastic force, so that the base 11 is in an elastic moving state. The vibration source provided by the vibration mechanism 30 is stable and the vibration effect is good. It can be understood that in other embodiments, the lengths of the four spring plate units 342 can also be equal, and the specific length can be set according to the actual situation.

[0078] To reduce the vibration and noise of the vibration mechanism 30, in this embodiment, the vibration mechanism 30 further includes a shock absorber 36 disposed on the side of the base 31 away from the vibrating plate 10. The shock absorber 36 is a shock-absorbing rubber pad. In this embodiment, there are four shock absorbers 36, which are respectively disposed at the four corners of the side of the base 31 away from the vibrating plate 10. Thus, by providing the aforementioned shock absorbers 36, the vibration and noise of the vibration mechanism 30 are reduced.

[0079] To enhance the protective performance of the vibration mechanism 30, in this embodiment, the vibration mechanism 30 further includes a protective cover 37 disposed on the base 31 and spaced apart from the base 11 of the vibrating plate 10. The protective cover 37 is annular and does not contact the base 11. The protective cover 37 surrounds the vibrator 32, the fixing post 33, and the elastic component 34. Thus, by providing the aforementioned protective cover 37, the protective performance of the vibration mechanism 30 is enhanced.

[0080] The guide rail assembly 40 is disposed on the enclosure 12 of the vibratory feeder 10 and located above the rubber pad assembly 20. In this embodiment, the guide rail assembly 40 is disposed inside the enclosure 12, with one end of the guide rail assembly 40 corresponding to the end point of the preset trajectory S. One end of the guide rail assembly 40 receives the material 200 conveyed along the preset trajectory S, and the other end of the guide rail assembly 40 extends to the discharge port 122. The guide rail assembly 40 conveys multiple materials 200 to the discharge port 122 according to preset requirements. In this embodiment, please refer to [reference needed]. Figure 6 The guide rail assembly 40 includes a guide rail 41 disposed on the enclosure 12 of the vibrating plate 10 and located between the rubber pad assembly 20 and the screening assembly 50, and an elastic rubber element 42 disposed on the guide rail 41 and including multiple rubber rods 422. The side of the guide rail 41 facing the screening assembly 50 is configured as a conveying inclined surface 412. The elastic rubber element 42 is disposed on the conveying inclined surface 412. One end of the elastic rubber element 42 receives the material 200 conveyed along a preset trajectory S, and the other end of the elastic rubber element 42 extends to the discharge port 122. Each rubber rod 422 of the elastic rubber element 42 is elastic, and each rubber rod 422 is inclined at a certain angle in the direction of material 200 movement. Understandably, the structure and material of the elastic rubber element 42 are roughly similar to those of the first rubber pad 22, the second rubber pad 23, the third rubber pad 24, the fourth rubber pad 25, and the spliced ​​rubber pad 26. Thus, when the material 200 vibrates from the rubber pad assembly 20 onto the elastic rubber part 42 of the guide rail assembly 40, since the rubber rod 422 of the elastic rubber part 42 is tilted at a certain angle toward the direction of material 200 movement, when the elastic rubber part 42 and the vibrating plate 10 vibrate together, the material 200 on the elastic rubber part 42 will move toward the direction of the tilt of the rubber rod 422, thereby moving multiple materials 200 to the discharge port 122.

[0081] The screening component 50 is set on the fence 12 of the vibrating plate 10 and located above the guide rail assembly 40. The screening component 50 screens out the material 200 that does not meet the preset requirements conveyed by the guide rail assembly 40. The material 200 that does not meet the preset requirements can be, for example, tilted material 200, upright material 200, material 200 placed upside down, etc.

[0082] To screen out inclined and upright materials 200, in this embodiment, the screening assembly 50 includes a first guide member 51 disposed on the guardrail 12 of the vibrating plate 10 and located above the guide rail assembly 40. The side of the first guide member 51 facing the material 200 in the direction of material inflow is configured as a guide slope 512. Thus, by setting the first guide member 51, when the inclined or upright material 200 moves under the conveying of the guide rail assembly 40, due to the higher height of the inclined or upright material 200, it hits the first guide member 51. Under the guidance of the guide slope 512 of the first guide member 51, the inclined or upright material 200 tilts away from the first guide member 51, causing instability and falling onto the rubber pad assembly 20. The material 200 that falls onto the rubber pad assembly 20 then moves again along a preset trajectory S under the vibration conveying of the rubber pad assembly 20. Understandably, in other embodiments, the height between the first guide member 51 and the guide rail assembly 40 can also be adjusted to accommodate the screening of materials 200 of different heights, thereby improving the versatility of the vibrating screen device 100.

[0083] To further ensure that the material 200 is conveyed out according to preset requirements, in this embodiment, the screening device also includes a second guide member 52 connected to the fence 12 of the vibrating plate 10 and located above the guide rail assembly 40. The first guide member 51 and the second guide member 52 are spaced apart along the moving direction of the material 200. The second guide member 52 includes a connecting plate 522 connected to the fence 12 of the vibrating plate 10 and located above the guide rail assembly 40, a limiting plate 524 with one end connected to the connecting plate 522 and the other end extending to one side of the guide rail assembly 40, and a limiting plate 524 connected to the connecting plate 522 and the other end extending to one side of the guide rail assembly 40. A guide portion 526 is connected to the side of the limiting plate 524 facing the first guide member 51. The first guide member 51 and the connecting plate 522 are spaced apart along the moving direction of the material 200. The connecting plate 522, the limiting plate 524, the guide rail assembly 40, and the fence 12 enclose a space adapted to the material 200. The guide portion 526 is roughly arc-shaped and guides the material 200 so that the material 200 can smoothly enter the space enclosed by the connecting plate 522, the limiting plate 524, the guide rail assembly 40, and the fence 12. After the first guide member 51 performs preliminary screening of the material 200, the material 200 moves to the second guide member 52 and adjusts its posture under the guidance of the guide portion 526. After the posture is adjusted by the guide portion 526, the material 200 enters the space enclosed by the connecting plate 522, the limiting plate 524, the guide rail assembly 40, and the fence 12 and moves to the discharge port 122 under the vibration conveying of the track assembly 40. Thus, by setting the second guide 52 mentioned above, the material 200 is conveyed to the discharge port 122 according to preset requirements.

[0084] To screen out materials 200 that are placed backwards, in this embodiment, the screening assembly 50 further includes a detector 53 disposed on the fence 12 of the vibrating plate 10 and located above the guide rail assembly 40, and an air blowing component 54 disposed outside the fence 12 of the vibrating plate 10 and located between the detector 53 and the guide rail assembly 40. The first guide component 51, the detector 53, and the second guide component 52 are spaced apart along the moving direction of the material 200. In this embodiment, the detector 53 is located between the first guide component 51 and the second guide component 52. The detector 53 can be a sensor. The detector 53 detects the material 200 on the guide rail assembly 40, for example, by detecting the barcode information on the material 200. If the detector 53 detects the barcode on the material 200, it is determined that the material 200 is placed backwards. Conversely, if the detector 53 does not detect the barcode on the material 200, it is determined that the material 200 is placed backwards. The air blowing component 54 is connected to an external air source and blows away the material 200 that has been detected by the detector 53 as being placed backwards. Thus, by setting up the detector 53 and the air blowing element 54, the material 200 that is placed in reverse order can be screened out, further improving the versatility of the vibrating screening device 100.

[0085] In actual use, the vibrating screening device 100 provided in this application embodiment pours multiple materials 200 into the vibrating plate 10. The vibration mechanism 30 provides a frequency-based vibration source for the vibrating plate 10, the rubber pad assembly 20, the guide rail assembly 40, and the screening assembly 50. The vibration mechanism 30 drives the vibrating plate 10, the rubber pad assembly 20, the guide rail assembly 40, and the screening assembly 50 to vibrate. The vibrating plate 10 vibrates the multiple materials 200 onto the rubber pad assembly 20. The multiple materials 200 are conveyed along a preset trajectory S under the vibration conveying of the multiple rubber columns 21 of the rubber pad assembly 20. When the materials 200 are conveyed under the vibration of the vibrating plate 10 and the rubber pad assembly 20, one end of the guide rail assembly 40 receives the materials conveyed along the preset trajectory S. The material 200 is conveyed to the discharge port 122 according to preset requirements through the vibration of the elastic rubber component 42. During the process of conveying the material 200 by the guide rail assembly 40, the first guide component 51, detector 53 and air blowing component 54 of the screening component 50 will also screen out the material 200 that does not meet the preset requirements conveyed by the guide rail assembly 40. The remaining material 200 that meets the requirements will move to the discharge port 122 under the limiting action of the second guide component 52 and be conveyed to the external equipment through the conveying plate 13. The material 200 that is screened out falls onto the rubber pad assembly 20 and is conveyed again along the preset trajectory S under the vibration of the rubber pad assembly 20, thereby realizing the automated screening of the material 200.

[0086] The vibrating screening device 100 provided in this application embodiment, through the coordinated operation of the vibrating plate 10, the rubber pad assembly 20, the vibration mechanism 30, the guide rail assembly 40, and the screening assembly 50, enables the material 200 to be conveyed out according to preset requirements, thereby achieving automated screening of the material 200, improving the screening efficiency of the material 200, reducing labor costs, and reducing the occurrence of collisions and scratches on the material 200. Furthermore, when the shape and size of the material 200 to be screened changes, the distance between the screening assembly 50 and the guide rail assembly 40 can be changed to accommodate materials 200 of different shapes and sizes; when the external equipment corresponding to the discharge port 122 is switched, the position of the rubber pad assembly 20 can be changed to alter the preset trajectory S, thus making it suitable for different external equipment. The vibrating screening device 100 has high versatility.
