Description

Technical Field

[0001] This utility model relates to the field of optical sorting machines, and in particular to a vibrating conveyor device for optical sorting machines. Background Technology

[0002] An optical sorting machine is a high-tech device based on machine vision and image processing technologies. It captures images of objects to be inspected using a high-precision camera and uses a computer to process and analyze the images in real time, thereby achieving accurate measurement and identification of features such as size, shape, and color of objects.

[0003] Vibrating conveyors are an important component of optical sorting machines, typically utilizing a vibrating motor fixed to a trough for conveying. The motor generates vibrations, which in turn cause the conveyor trough to vibrate, rapidly transporting material from the inlet to the outlet. However, existing vibrating conveyors in optical sorting machines often have excessively large feed rates, potentially leading to material accumulation. This can interfere with the imaging system, causing image blurring or obstruction, and ultimately reducing detection accuracy.

[0004] Therefore, this utility model proposes a vibrating conveyor for an optical sorting machine. Utility Model Content

[0016] Preferably, the lower end of the base is provided with multiple shock-absorbing rubber pads.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] (1) The optical sorting machine uses a vibrating conveyor device, including gears; racks are meshed on both sides of the gears; connecting boxes are fixedly connected to both racks; a second slide groove is opened at the lower end of the connecting box; a slider is slidably connected in the second slide groove; a baffle plate is fixedly connected to the lower end of the slider. By starting the second motor, the second rotating shaft and the gears are driven to rotate, thereby driving the racks on both sides to move relative to each other, and causing the two baffle plates to descend alternately, thereby controlling intermittent feeding and ensuring that only a small amount of material enters the detection area each time, avoiding image blurring due to material overlap or obstruction, thereby improving detection accuracy. When abnormal material is detected, a small amount of feeding can also be used in conjunction with a pneumatic rejection device to achieve accurate sorting, avoiding continuous feeding that leads to a large accumulation of material and the mistaken rejection of qualified products or the omission of defective products.

[0019] (2) The optical screening machine uses a vibrating conveyor device. The side wall of the connecting box has multiple through holes (I); each through hole (I) communicates with a slide groove (II); the side wall of the slider has through holes (II); and positioning rods are inserted into the through holes (I) and (II). By pushing the baffle plate, the slider slides along the slide groove (II), and then the positioning rods are rotated and inserted into the corresponding through holes (I) and (II). The distance between the two baffle plates can be adjusted to accommodate materials of different sizes, and it is also convenient to adjust the amount of material fed each time, thus improving the applicability and flexibility of the device.

[0020] (3) The optical screening machine uses a vibrating conveyor device, including a partition plate set in the middle of the spiral track; a connecting frame 1 fixedly connected to the spiral track is provided on the side of the partition plate near the intermittent feeding component; a motor 1 is provided on the connecting frame 1; a rotating shaft 1 is connected to the drive end of the motor 1; the rotating shaft 1 is rotatably connected to the connecting frame 1, and a baffle is connected to its side wall. The material is dispersed to both sides by the partition plate, and then the motor 1 is started to drive the rotating shaft 1 to rotate, thereby driving the baffle to swing back and forth, thereby intermittently blocking the material on one side separated by the partition plate, while allowing the material on the other side to flow, which can initially disperse the material and avoid the material from accumulating in large quantities and causing blockage.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figure 1-4 As shown in the figure, the vibrating conveying device for an optical screening machine provided by this utility model embodiment includes a base 1, a hopper 2, a diverter 6, and an intermittent feeding assembly 7. The hopper 2 is disposed above the base 1; multiple spring plates 3 are connected between the hopper 2 and the base 1; an electromagnet 4 is provided at the lower end of the hopper 2, and a spiral track 5 is fixedly connected to the inner wall. The diverter 6 is disposed on the spiral track 5 and is used to disperse the material to both sides. The intermittent feeding assembly 7 is disposed at the end of the spiral track 5 and is used to intermittently block the material, so that the material is fed intermittently; the intermittent feeding assembly 7 includes a gear 74; racks 75 are meshed on both sides of the gear 74; connecting boxes 78 are fixedly connected to both racks 75; a second groove 79 is provided at the lower end of the connecting box 78; a slider 710 is slidably connected in the second groove 79; a baffle plate 711 is fixedly connected to the lower end of the slider 710.

[0029] Further explanation: The diverter 6 includes a partition plate 61 positioned in the middle of the spiral track 5; the partition plate 61 disperses the material to both sides; a connecting frame 62, fixedly connected to the spiral track 5, is located on the side of the partition plate 61 near the intermittent feeding assembly 7; a motor 63 is mounted on the connecting frame 62; a rotating shaft 64 is connected to the drive end of the motor 63; the rotating shaft 64 is rotatably connected to the connecting frame 62, and a baffle 65 is connected to its side wall. By controlling the reciprocating swing of the baffle 65 through the motor 63, the material on one side separated by the partition plate 61 is intermittently blocked, while the material on the other side flows, thus initially dispersing the material and preventing large-scale accumulation of material that could cause blockage.

[0030] Further explanation: The intermittent feeding assembly 7 also includes a connecting frame 71 fixedly mounted on both sides of the spiral track 5; a motor 72 is mounted on one side of the connecting frame 71; the drive end of the motor 72 is connected to a rotating shaft 73; the rotating shaft 73 is rotatably connected to the side wall of the connecting frame 71; a gear 74 is mounted on the rotating shaft 73 and is coaxial with the rotating shaft 73. Slide rods 76 are connected to both ends of the rack 75; sliding grooves 77 are respectively opened on both sides of the connecting frame 71; the slide rods 76 are slidably connected in the corresponding sliding grooves 77. This causes the two baffle plates 711 to descend alternately, thereby controlling the intermittent feeding and ensuring that only a small amount of material enters the detection area each time, avoiding image blurring due to material overlap or obstruction, thus improving detection accuracy. When abnormal material is detected, the small amount of feeding can also be combined with a pneumatic rejection device to achieve precise sorting, avoiding the large accumulation of material caused by continuous feeding, which could lead to the incorrect rejection of qualified products or the omission of defective products.

[0031] Further explanation: The side wall of the connecting box 78 has multiple through holes 712; all through holes 712 communicate with the slide groove 79; the side wall of the slider 710 has through holes 713; positioning rods 714 are inserted into the through holes 712 and 713. The through holes 712 are equidistantly arranged. By inserting the positioning rods 714 into the corresponding through holes 712 and 713, the position of the barrier plate 711 can be fixed, preventing the barrier plate 711 from shaking when blocking materials. The positioning rods 714 are threaded rods; the through holes 713 are fitted with the positioning rods 714, thus making the positioning rods 714 and through holes 713 more tightly engaged. One end of the positioning rods 714 is fixedly connected to a limiting pad 715; the diameter of the limiting pad 715 is larger than the diameter of the through holes 712. The positioning rod 714 is easily twisted, preventing it from sinking into the through hole 713. The lower end of the baffle plate 711 has a ramp. This ramp allows the baffle plate 711 to push the material below it to the side as it descends, preventing material from obstructing its descent and causing equipment malfunction. The distance between the two baffle plates 711 can be adjusted by allowing the slider 710 to slide within the groove 79, thus accommodating materials of different sizes and facilitating adjustments to the feed quantity each time, improving the applicability and flexibility of the device.

[0032] To further explain, the lower end of the base 1 is provided with multiple shock-absorbing rubber pads 8.

[0033] The working principle of this utility model is as follows: During operation, the material is first fed into the hopper 2, and then the electromagnet 4 is activated, causing the material to move along the spiral track 5 towards the intermittent feeding assembly 7. When the material passes through the diverter 6, the partition plate 61 disperses the material to both sides. Then, the motor 63 is activated to drive the rotating shaft 64 to rotate, thereby causing the baffle 65 to swing back and forth, thus intermittently blocking the material on one side separated by the partition plate 61, while allowing the material on the other side to flow. This initially disperses the material and prevents it from accumulating in large quantities and causing blockage. Next, the motor 72 is activated to drive the rotating shaft 73 and the gear 74 to rotate, thereby causing the racks 75 on both sides to move relative to each other, and causing the two baffle plates 711 to descend alternately, thereby controlling the intermittent feeding and ensuring that only a small amount of material enters the detection area each time, avoiding image blurring due to material overlap or obstruction, thereby improving detection accuracy. When the feed quantity needs to be adjusted, push the baffle plate 711 to make the slider 710 slide along the second slide groove 79, and then rotate the positioning rod 714 into the corresponding through hole 712 and through hole 713 to fix the position of the baffle plate 711.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
