Description

Technical Field

[0001] This application relates to the field of feeding machine technology, and more particularly to a feeding and turning machine suitable for small bolts. Background Technology

[0002] When conveying bolts, it is often necessary to lift and convey the bolts in the hopper to facilitate subsequent transportation and processing. Therefore, a loading tilting machine is usually used in the conveying process. After the material is conveyed to a high place, the loading hopper is tilted so that the material in it falls into the conveying frame above for further conveying. However, in some existing loading tilting machines, when the loading hopper leaves from below, there is no loading hopper below to receive the material, so the hopper below will stop discharging to prevent the material from falling to the ground. When the loading hopper moves to the bottom, it will start discharging again. However, since the amount of material discharged is limited by the discharge frame, the discharge time is constant. In addition, the time for the loading hopper to move up and down makes the entire loading and unloading process take a long time. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies, such as the long loading and unloading process, by proposing a loading and turning machine suitable for small bolts.

[0004] To achieve the above objectives, this application adopts the following technical solution: a feeding and turning machine suitable for small bolts, comprising a base and a conveying frame fixedly installed thereon, a feeding frame fixedly installed at the top of the conveying frame, a hopper fixedly installed inside the base, a discharge frame fixedly installed at the bottom of the hopper, a limit cover rotatably installed on the inner wall of the base, a first cylindrical rod fixedly installed on the surface of the limit cover, a storage frame rotatably installed on the inner wall of the base, a side frame fixedly installed on the side wall of the storage frame, and a bottom rod horizontally slidably installed on the inner wall of the base;

[0005] A sliding frame is vertically slidably installed on the inner wall of the conveying frame, and the sliding frame moves up and down inside the conveying frame via a driving mechanism. A transport frame is rotatably installed on the sliding frame, a transport hopper is slidably installed on the transport frame, a limit frame is fixedly installed on the transport frame, a second cylindrical rod is fixedly installed on the conveying frame, and a pull plate is fixedly installed on the sliding frame.

[0006] Preferably, the driving mechanism includes an upper sprocket and a lower sprocket rotatably mounted in the conveying frame, and a servo motor is fixedly mounted in the conveying frame. The output end of the servo motor is fixedly connected to the upper sprocket, and a chain is installed between the upper sprocket and the lower sprocket. A connecting block is fixedly mounted on the slide frame, and the connecting block is fixedly connected to the chain.

[0007] Preferably, a protruding plate is fixedly installed on the sliding frame, and a limiting shaft is fixedly installed on the transport frame, with the limiting shaft rotatably installed inside the protruding plate.

[0008] Preferably, a magnet is fixedly installed on the surface of the sliding frame, and an iron sheet is fixedly installed at the bottom of the transport frame.

[0009] Preferably, a limiting plate is fixedly installed on the inner wall of the base, and a reset spring is fixedly installed between the limiting plate and the side frame.

[0010] Preferably, a rotating shaft is fixedly installed on the limiting cover, and the rotating shaft and the base are rotatably connected by a torsion spring.

[0011] Preferably, a sliding rod is fixedly installed at the bottom end of the transport bucket, a fixing plate is fixedly installed at the bottom end of the transport frame, a tension spring is fixedly installed between the fixing plate and the sliding rod, an abutment plate is fixedly installed at the bottom end of the transport frame, and a chamfer is provided on the abutment plate, and an inclined block is fixedly installed at the bottom end of the sliding rod.

[0012] In summary,

[0013] In this application, when the conveyor bucket moves upward, the material discharge process of the bucket continues, but at this time the material on the discharge frame will flow into the storage frame through the limiting cover and be stored until the conveyor bucket descends. The sliding frame will drive the limiting cover to flip, thereby opening the discharge frame and the storage frame at the same time. At this time, the discharge frame and the storage frame will drop material into the conveyor bucket at the same time, thereby speeding up the time for the conveyor belt to be filled, thus saving the entire loading and unloading process.

[0021] Reference Figure 1-6 As shown, this application provides a technical solution: a feeding and turning machine suitable for small bolts, including a base 1 and a conveying frame 2 fixedly installed thereon. A feeding frame 3 is fixedly installed at the top of the conveying frame 2. A hopper 7 is fixedly installed inside the base 1. A discharge frame 81 is fixedly installed at the bottom of the hopper 7. A limit cover 82 is rotatably installed on the inner wall of the base 1. A first cylindrical rod 83 is fixedly installed on the surface of the limit cover 82. A storage frame 84 is rotatably installed on the inner wall of the base 1. A side frame 85 is fixedly installed on the side wall of the storage frame 84. A bottom rod 86 is horizontally slidably installed on the inner wall of the base 1.

[0022] A sliding frame 91 is vertically slidably installed on the inner wall of the conveying frame 2, and the sliding frame 91 moves up and down in the conveying frame 2 through a drive mechanism. A transport frame 92 is rotatably installed on the sliding frame 91, a transport bucket 93 is slidably installed on the transport frame 92, a limit frame 94 is fixedly installed on the transport frame 92, a second cylindrical rod 99 is fixedly installed on the material conveying frame 3, and a pull plate 912 is fixedly installed on the sliding frame 91.

[0023] When the sliding frame 91 moves downward via the drive mechanism, the pull plate 912 on it will contact the first cylindrical rod 83. At this time, the pull plate 912 will pull the first cylindrical rod 83 downward, causing the first cylindrical rod 83 to cause the limiting plate 87 to flip downward. Simultaneously, the screws in the discharge frame 81 will fall into the transport hopper 93. At the same time, the limiting cover 82 moves to the bottom of the storage frame 84, and as the limiting cover 82 moves, it will push the bottom rod 86 to move. The bottom rod 86 will then push the side frame 85 to rotate, causing the side frame 85 to rotate. The storage frame 84 will then rotate towards the transport hopper 93, thus causing the screws in the storage frame 84 to also fall into the transport hopper 93. After the screws are loaded into the conveying hopper 93, the drive mechanism moves the sliding frame 91 upward until the limiting frame 94 on the conveying frame 92 contacts the second cylindrical rod 99. At this time, the second cylindrical rod 99 enters the limiting frame 94 from the upper opening. As the limiting frame 94 continues to move upward, the second cylindrical rod 99 pushes the inner bottom wall of the limiting frame 94, thereby causing the conveying frame 92 to rotate. At this time, the conveying frame 92 will drive the conveying hopper 93 to rotate, thereby pouring the screws in the conveying hopper 93 into the conveying frame 3 to complete the lifting and conveying. When the sliding frame 91 moves downward, the second cylindrical rod 99 drives the conveying frame 92 to flip over through the limiting frame 94.

[0024] If a large number of small bolts are transported at once during the conveying process, the lower part is easily crushed. Therefore, by flipping the conveyor bucket 93 during the conveying process, the small bolts at the bottom can be flipped up to adjust their position and avoid being crushed at the bottom.

[0025] Specifically, the drive mechanism includes an upper sprocket 4 and a lower sprocket 5 rotatably installed in the conveyor frame 2, and a servo motor is fixedly installed in the conveyor frame 2. The output end of the servo motor is fixedly connected to the upper sprocket 4, and a chain is installed between the upper sprocket 4 and the lower sprocket 5. A connecting block 6 is fixedly installed on the slide frame 91, and the connecting block 6 is fixedly connected to the chain.

[0026] The sliding frame 91 is kept within the conveying frame 2 by the connecting block 6, and at the same time, the upper sprocket 4 is driven to rotate by the servo motor. At this time, the upper sprocket 4 will drive the sliding frame 91 to move up and down through the chain.

[0027] Specifically, a protruding plate 911 is fixedly installed on the sliding frame 91, and a limiting shaft is fixedly installed on the transport frame 92, with the limiting shaft rotatably installed inside the protruding plate 911;

[0028] The cooperation between the limiting shaft and the protruding plate 911 facilitates the rotation of the transport frame 92 on the sliding frame 91.

[0029] Specifically, a magnet is fixedly installed on the surface of the sliding frame 91, and an iron sheet is fixedly installed at the bottom of the transport frame 92.

[0030] When the sliding frame 91 moves to the correct position, it is attracted together by the magnet and the iron sheet, thus preventing the transport frame 92 from flipping over randomly.

[0031] Specifically, a limiting plate 87 is fixedly installed on the inner wall of the base 1, and a reset spring is fixedly installed between the limiting plate 87 and the side frame 85.

[0032] When the base rod 86 pushes the side frame 85 to rotate, the return spring will be compressed, and at the same time, refer to Figure 6 When the side frame 85 rotates, it will drive the storage frame 84 to rotate slightly counterclockwise, thereby causing the storage frame 84 to discharge material.

[0033] Specifically, a rotating shaft 821 is fixedly installed on the limiting cover 82, and the rotating shaft 821 and the base 1 are rotatably connected by a torsion spring;

[0034] When the transport bucket 93 moves upward and away, the torsion spring drives the limit cover 82 to rotate and reset. Figure 6 In the state shown, the screws in hopper 7 will slide onto the limiting cover 82 via the discharge frame 81, and then move into the storage frame 84 via the limiting cover 82. At this time, the storage frame 84 tilts to the lower right, so that the screws falling on it are stored. When the sliding frame 91 descends, it drives the first cylindrical rod 83 to descend via the pull plate 912. At this time, the first cylindrical rod 83 will drive the limiting plate 87 to move downward and rotate. (Refer to...) Figure 6 At this time, the limiting cover 82 will move to the bottom of the storage frame 84. Then the limiting cover 82 will contact the abutment rod, thereby pushing the bottom rod 86 to slide. At this time, the bottom rod 86 will push the side frame 85 to drive the storage frame 84 to rotate until the storage frame 84 rotates counterclockwise to facilitate the material stored on it to fall into the conveyor hopper 93. The limiting cover 82 can receive the falling material to facilitate it to fall into the conveyor hopper 93, thereby extending the discharge channel.

[0035] Specifically, a sliding rod 95 is fixedly installed at the bottom of the transport bucket 93, a fixing plate 931 is fixedly installed at the bottom of the transport frame 92, a tension spring 98 is fixedly installed between the fixing plate 931 and the sliding rod 95, an abutment plate 97 is fixedly installed at the bottom of the conveying frame 2, and a chamfer is provided on the abutment plate 97, and an inclined block 96 is fixedly installed at the bottom of the sliding rod 95.

[0036] As the sliding frame 91 moves downward, the inclined side of the bottom inclined block 96 of the sliding rod 95 will contact the chamfer on the abutment plate 97. At this time, the transport hopper 93 will move horizontally on the transport frame 92, so that the transport hopper 93 is closer to the discharge frame 81 and the storage frame 84, thus facilitating the receiving of materials. The tension spring 98 will pull the transport hopper 93 back to its original position when the sliding frame 91 moves upward away from the abutment plate 97. At the same time, the magnet and iron plate also prevent the abutment plate 97 from directly lifting the transport hopper 93 and causing it to rotate.

[0037] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above description and drawings are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
