Description

Technical Field

[0001] This utility model belongs to the field of steel ball feeding technology, and in particular relates to a steel ball feeding and conveying device. Background Technology

[0002] Steel balls are categorized by manufacturing process into ground steel balls, forged steel balls, and cast steel balls. They are also classified by material into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, and alloy balls. Bearing steel balls are crucial basic components in industry. Alloy steel balls are spherical iron alloy wear-resistant bodies made primarily of carbon, chromium, manganese, and molybdenum, produced through forging, spinning, rolling, and casting. They are a vital component in modern crushing industries, mining, and cement production. The technology of automated steel ball conveying and feeding devices has developed gradually with the increasing demand for industrial automation. Modern steel ball conveying and feeding systems not only improve production efficiency but also ensure production accuracy, reduce the need for manual intervention, and enhance the overall reliability and stability of production. With the integration of intelligent manufacturing and the Internet of Things (IoT) technologies, the technology of automated steel ball feeding devices will continue to innovate, becoming more intelligent, efficient, and environmentally friendly in the future.

[0003] Among the existing published patents, Chinese Patent CN105197514A discloses a steel ball screw feeding device, which includes a rotation drive device and a main body of the steel ball screw feeding device. The main body of the steel ball screw feeding device includes two sets of screw feeding mechanisms, each of which includes a feeding disc, a storage bin, and a return disc. The feeding disc is provided with a feeding screw channel, and the return disc is provided with a return screw channel. The rotation direction of the return screw channel is opposite to that of the feeding screw channel. The return screw channel is provided with a return chamber. During operation, the feeding disc and the return disc rotate in the opposite direction to the rotation direction of the feeding screw channel. Steel balls enter the feeding screw channel, most of the steel balls are eliminated from the elimination chamber and returned to the return screw channel and recycled to the storage bin, and the remaining steel balls are output from the steel ball outlet, thus realizing continuous output of steel balls and achieving the buffer storage function.

[0004] However, existing technologies have some problems: the steel ball feeding and conveying device mentioned above adopts a spiral continuous feeding mode. The feeding time of this continuous feeding mode is uncontrollable and cannot achieve real-time feeding according to feeding needs. In semi-automatic equipment or devices where the steel ball feeding time is not fixed, workers can only feed when feeding is needed. In order to enable workers to achieve real-time feeding when feeding is needed, we propose a steel ball feeding and conveying device. Utility Model Content

[0026] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] like Figures 1 to 5 As shown, the present invention provides a steel ball feeding and conveying device, including a support platform 1, a drive motor 2 fixedly connected at the center of the upper part of the support platform 1, a discharge turntable 3 above the drive motor 2, a support leg at the bottom of the discharge turntable 3, and several sets of S-shaped conveying pipes 4 evenly arranged around the bottom circumference of the discharge turntable 3, the S-shaped conveying pipes 4 being hollow.

[0028] The top end of the S-shaped conveying pipe 4 is fixedly connected to the bottom of the discharge turntable 3. A support leg is provided in the middle of the S-shaped conveying pipe 4. A baffle 420 is fixedly connected inside the bottom pipe of the S-shaped conveying pipe 4. A rotating door 430 is rotatably connected to the bottom end of the S-shaped conveying pipe 4. A drive connecting rod 442 is rotatably connected to the outside of the rotating door 430. An arc-shaped connecting rod 443 is rotatably connected to one end of the drive connecting rod 442. The middle of the arc-shaped connecting rod 443 is rotatably connected to the bottom of the S-shaped conveying pipe 4. An arc-shaped push plate 444 is rotatably connected to the end of the arc-shaped connecting rod 443 away from the drive connecting rod 442. The arc-shaped push plate 444 penetrates the bottom of the S-shaped conveying pipe 4 and is slidably set with the S-shaped conveying pipe 4.

[0029] Furthermore, the discharge turntable 3 is hollow, and a base plate 310 is fixedly connected to the bottom of the discharge turntable 3. The base plate 310 has a discharge hole 320 corresponding to the S-shaped conveying pipe 4. A rotating rod 330 is rotatably connected to the center of the base plate 310. Two sets of rotating plates 340 are symmetrically fixedly connected to the side of the rotating rod 330. The bottom of the rotating rod 330 penetrates the base plate 310. The rotating rod 330 is fixedly connected to the output shaft of the drive motor 2.

[0030] It should be noted that the drive motor 2 drives the rotating plate 340 to move the steel balls on the discharge turntable 3 into multiple sets of S-shaped conveying pipes 4. The steel balls are conveyed and fed by their own weight, and the feeding of the multiple sets of S-shaped conveying pipes 4 is not affected, which reduces resource waste and improves the conveying efficiency of the conveying device.

[0031] Furthermore, the top end of the S-shaped conveying pipe 4 is provided with a feed hole 410, and the feed hole 410 is positioned corresponding to the discharge hole 320.

[0032] It should be noted that the feed hole 410 and the discharge hole 320 are positioned correspondingly, and the diameters of the feed hole 410 and the discharge hole 320 are slightly larger than the diameter of the steel ball, making it easier for the steel ball to enter the S-shaped conveying pipe 4 from the discharge turntable 3.

[0033] Furthermore, a rotating shaft 441 is provided between the rotating door 430 and the S-shaped conveying pipe 4, and the bottom ends of the rotating door 430 and the S-shaped conveying pipe 4 are rotatably connected through the rotating shaft 441.

[0034] It should be noted that the opening and closing of the revolving door 430 is controlled by the operator through the switching device to control the switching and forward and reverse rotation of the servo motor 440 according to the material supply requirements, so as to flexibly supply materials and improve the applicability and flexibility of the equipment.

[0035] Furthermore, a servo motor 440 is provided on one side of the rotating shaft 441. The servo motor 440 is fixedly connected to the S-shaped feed tube 4, and the output shaft of the servo motor 440 is fixedly connected to the rotating shaft 441.

[0036] It should be noted that when workers need to supply materials, they can control the switching and forward / reverse rotation of the servo motor 440 by operating the switching device of the servo motor 440, thereby controlling the rotating door 430 and realizing real-time control of the material supply.

[0037] Furthermore, the side of the baffle 420 near the arc-shaped push plate 444 is set as a curved surface, and the inner arc surface of the arc-shaped push plate 444 is slidably fitted with the curved surface of the baffle 420.

[0038] It should be noted that by fitting the inner arc surface of the arc-shaped push plate 444 with the curved surface of the baffle 420, the gap between the two is eliminated, avoiding the situation where the steel ball is easily stuck in the gap, and enabling smooth delivery of the steel ball.

[0039] Furthermore, the baffle 420 is located between the arc-shaped push plate 444 and the revolving door 430, and there is space between the top of the baffle 420 and the inside of the pipe.

[0040] It should be noted that there is space between the upper end of the baffle 420 and the inside of the pipe for the steel ball to pass through. The width of the arc-shaped push plate 444 can only carry one steel ball at a time. The arc-shaped push plate 444 pushes the steel ball upward to the same height as the baffle 420, and delivers the steel ball to the front of the revolving door 430. This ensures that there is only one steel ball in front of the revolving door 430 at a time, avoiding the situation where multiple steel balls are supplied to the subsequent mechanism at the same time, which can easily cause confusion and improve the accuracy of production.

[0041] Furthermore, the upper surfaces of the arc-shaped push plate 444 and the baffle 420 are designed with concave curved surfaces and the two curved surfaces are set flush with each other. The curvature of the curved surfaces is the same as the curvature of the inner curved surface of the S-shaped conveying pipe 4.

[0042] It should be noted that, in order to ensure that the steel balls can be smoothly conveyed in the S-shaped conveying pipe 4, the contact surfaces of the arc-shaped push plate 444 and the baffle 420 with the steel balls are set as concave curved surfaces, which can reliably support the steel balls for transportation.

[0043] Examples of this application:

[0044] Initial state: The rotating door 430 is in the open state, and the upper curved surface of the arc-shaped push plate 444 is flush with the inner curved surface of the S-shaped conveying pipe 4.

[0045] Conveying process: The operator puts the steel ball into the discharge turntable 3 and starts the drive motor 2. The drive motor 2 drives the rotating plate 340 to rotate through the rotating rod 330. Under the drive of the rotating plate 340, the steel ball enters the S-shaped conveying pipe 4 through the discharge hole 320 on the bottom plate 310. After entering the S-shaped conveying pipe 4, the steel ball enters the arc-shaped push plate 444 by its own gravity and is blocked by the arc-shaped push plate 444.

[0046] Feeding process: The operator controls the switch to start the servo motor 440, which drives the rotating shaft 441 to rotate the rotating door 430 inward to close the rotating door 430. At the same time, the arc-shaped connecting rod 443 drives the arc-shaped push plate 444 to push the steel ball upward. The arc-shaped push plate 444 slides upward until its curved surface is flush with the upper curved surface of the baffle 420. The steel ball passes over the baffle 420 and comes to the front of the rotating door 430. The servo motor 440 reverses, and the rotating door 430 opens when it rotates outward. The steel ball is then transported to the subsequent mechanism through the rotating door 430, ensuring that only one steel ball is supplied at a time.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
