Description

Technical Field

[0001] This utility model relates to the field of plastic gear sorting technology, specifically an automatic sorting device for plastic gear production. Background Technology

[0002] Plastic gears are gears made of plastic, offering advantages such as light weight, low cost, corrosion resistance, and self-lubrication. They are widely used in home appliances, toys, automobiles, and office equipment. Compared to metal gears, plastic gears exhibit better performance under low-speed, light-load conditions, effectively reducing noise and vibration. Their manufacturing process typically includes injection molding, enabling high-precision production of complex shapes. The performance of plastic gears is significantly affected by the material and the working environment; for example, changes in temperature and humidity can affect their strength and dimensional stability.

[0003] Existing plastic gear sorting technologies mostly rely on manual visual inspection or simple mechanical screening, which is inefficient and prone to missed detections. Traditional sorting devices often use belt conveyors combined with fixed baffles for coarse screening, but they cannot adapt to the size differences of gears of different specifications, and are prone to multiple gears overlapping or jamming, leading to detection failure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic sorting device for plastic gear production, including a belt conveyor, a fixed baffle installed inside the belt conveyor, a feeding platform fixedly connected to the inner wall of the fixed baffle, a detection platform installed on the surface of the fixed baffle, and a limit component fixedly connected to the surface of the fixed baffle.

[0005] The limiting component includes a mounting frame, with a mounting box fixedly connected to the left end of the mounting frame. A servo motor is installed inside the mounting box, and a positive and negative lead screw is fixedly connected to the output end of the servo motor. A moving stage is threaded onto the surface of the positive and negative lead screw. A limiting partition is fixedly connected to the bottom of the moving stage. A sliding hole is opened on the surface of the limiting partition, and a sliding column is slidably connected inside the sliding hole. A slider is fixedly connected to the top of the moving stage, and a slide rail is slidably connected to the surface of the slider.

[0006] Through the above technical solution, the fixed baffle and the unloading platform form a guide channel. After the plastic gear slides down to the belt conveyor by gravity, the limiting component forces the gear to pass through the detection table in a single row by adjusting the spacing of the limiting baffle, thus ensuring the accuracy of detection and sorting.

[0007] As a further improvement to the above solution, the top of the testing platform is located above the belt conveyor, and the limiting component is located between the unloading platform and the testing platform.

[0008] The above technical solution places the testing platform above the belt conveyor, with the limiting component located between the unloading platform and the testing platform, optimizing the spatial layout. This design ensures that the gears are constrained by the limiting partition before entering the testing area, preventing multiple gears from triggering the sensor simultaneously.

[0009] As a further improvement to the above solution, two moving platforms are provided, which are symmetrically and evenly distributed on the surface with respect to the top center of the positive and negative lead screws.

[0010] The above technical solution employs two symmetrically distributed moving platforms, which move in opposite directions via positive and negative lead screws, thereby achieving synchronous adjustment of the spacing between the limiting partitions.

[0011] As a further improvement to the above solution, the sliding column passes through the sliding hole, and the left and right ends of the sliding column are fixedly connected to the inner wall of the mounting bracket.

[0012] Through the above technical solution, the sliding column passes through the sliding hole and is fixed to the mounting frame, providing lateral guidance for the moving stage. During operation, the sliding column restricts the offset of the moving stage, causing it to move only along the axial direction of the positive and negative lead screws, preventing the limit plate from tilting or jamming, and ensuring the accuracy and reliability of the limit action.

[0013] As a further improvement to the above solution, the top of the slide rail is fixedly connected to the top of the mounting bracket.

[0014] The slide rail is fixed to the top of the mounting bracket and cooperates with the slider to form the longitudinal guide rail of the moving stage. This design converts the lifting motion of the moving stage into linear motion along the slide rail.

[0015] As a further improvement to the above solution, a connecting frame is fixedly connected to the bottom of the fixed baffle, a support plate is fixedly connected to the bottom of the connecting frame, and a fixing pad is fixedly connected to the bottom of the support plate.

[0016] As a further improvement to the above solution, the number of fixing pads is set to four, and the four fixing pads are evenly distributed on the surface symmetrically with respect to the bottom center of the support plate.

[0017] The above technical solution uses four symmetrically distributed fixing pads to lift the entire device, preventing it from directly contacting the ground.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention utilizes a limiting component and a servo motor to drive forward and reverse lead screws to adjust the distance between the moving platforms, thereby achieving dynamic opening and closing of the limiting partition. During operation, the two moving platforms move in opposite directions along the forward and reverse lead screws, precisely controlling the throughput of the plastic gears on the belt conveyor. This ensures that each gear passes through the inspection table sequentially, effectively avoiding missed detections caused by overlapping or parallel inspections of multiple gears, and significantly improving sorting accuracy and efficiency.

[0020] This invention, by setting a slider and a sliding post, allows the slider to slide inside the slide rail and the limiting partition to slide on the surface of the sliding post when the limiting partition moves to both sides, thereby limiting its position. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 An automatic sorting device for plastic gear production according to this embodiment includes a belt conveyor 1, a fixed baffle 2 installed inside the belt conveyor 1, a feeding platform 3 fixedly connected to the inner wall of the fixed baffle 2, a detection platform 4 installed on the surface of the fixed baffle 2, and a limit component 5 fixedly connected to the surface of the fixed baffle 2.

[0030] The limiting component 5 includes a mounting frame 51. A mounting box 52 is fixedly connected to the left end of the mounting frame 51. A servo motor 53 is installed inside the mounting box 52. A positive and negative lead screw 54 is fixedly connected to the output end of the servo motor 53. A moving stage 55 is threadedly connected to the surface of the positive and negative lead screw 54. A limiting partition 56 is fixedly connected to the bottom of the moving stage 55. A sliding hole 57 is opened on the surface of the limiting partition 56. A sliding column 58 is slidably connected inside the sliding hole 57. A slider 59 is fixedly connected to the top of the moving stage 55. A slide rail 510 is slidably connected to the surface of the slider 59. When the servo motor 53 is started, the output end of the servo motor 53 drives the positive and negative lead screw 54 to rotate. The rotation of the positive and negative lead screw 54 drives the two moving stages 55 to move in opposite directions, thereby increasing or decreasing the distance between the two limiting partitions 56, so as to limit the position of the plastic gear when transporting the plastic gear.

[0031] The top of the inspection table 4 is located above the belt conveyor 1, and the limiting component 5 is located between the unloading table 3 and the inspection table 4.

[0032] There are two moving stages 55. The two moving stages 55 are symmetrically and evenly distributed on the surface with the top center of the positive and negative lead screws 54. By using two symmetrically distributed moving stages 55 and driving them to move in opposite directions through the positive and negative lead screws 54, the synchronous adjustment of the spacing between the limit partitions 56 is achieved.

[0033] The sliding column 58 passes through the sliding hole 57, and the left and right ends of the sliding column 58 are fixedly connected to the inner wall of the mounting bracket 51.

[0034] The top of the slide rail 510 is fixedly connected to the top of the mounting bracket 51.

[0035] A connecting frame 6 is fixedly connected to the bottom of the fixed baffle 2, a support plate 7 is fixedly connected to the bottom of the connecting frame 6, and a fixing pad 8 is fixedly connected to the bottom of the support plate 7.

[0036] The number of fixing pads 8 is set to four, and the four fixing pads 8 are evenly distributed on the surface symmetrically with respect to the bottom center of the support plate 7.

[0037] The implementation principle of an automatic sorting device in the production of plastic gears in this application embodiment is as follows: when the plastic gears are automatically sorted, the plastic gears are first put into the top of the unloading platform 3, so that the plastic gears slide from the unloading platform 3 onto the surface of the belt conveyor 1 for conveying. After being inspected by the inspection platform 4, the subsequent sorting work is carried out.

[0038] The servo motor 53 is started by the limiting partition 56. The output of the servo motor 53 drives the positive and negative lead screws 54 to rotate. The rotation of the positive and negative lead screws 54 drives the two moving tables 55 to move in opposite directions, thereby increasing or decreasing the distance between the two limiting partitions 56. This is to limit the position of the plastic gears during the transportation of plastic gears, so that they can only pass through the bottom of the detection table 4 one by one for detection. This avoids multiple gears passing directly under the detection table 4 at the same time, which would result in incomplete detection and prevent subsequent sorting.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
