Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of nail processing technology, and more specifically, to a feeding mechanism for a nail-laying machine. Background Technology
[0002] Some early nail bar feeding mechanisms relied solely on simple vibratory feeders, which could not precisely control the conveying speed and direction of the nails. This resulted in nails easily jamming and piling up during transport, severely impacting the continuity and stability of production. Furthermore, some existing nail bar feeding mechanisms lacked compatibility with different nail specifications. As market demand for diverse nail specifications increased, companies often needed to frequently replace or make complex adjustments to the feeding mechanisms to adapt to the production of different specifications. This undoubtedly increased production costs and equipment maintenance difficulties, reducing the company's production flexibility and market competitiveness. Meanwhile, in some nail production environments, there are also high requirements for the safety and environmental protection of equipment. However, traditional feeding mechanisms may pose certain safety hazards during operation due to the high-speed operation of components or unreasonable structural design, which may threaten the personal safety of operators. Moreover, some feeding mechanisms generate a lot of noise and dust during operation, which not only pollutes the production environment but may also harm the health of operators. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a feeding mechanism for a nail packing machine, which solves the technical problem that the feeding mechanism of the early nail packing machine in the prior art only uses a simple vibratory plate for feeding, which cannot accurately control the conveying speed and direction of the nails, and the nails are prone to jamming and accumulation during the conveying process, which seriously affects the continuity and stability of production.
[0004] According to one aspect, at least one embodiment of this disclosure provides a feeding mechanism for a nail-staple machine, comprising: A feeding pipe, wherein a support frame is provided on the lower end face of the feeding pipe; A feeding push assembly is disposed at the end of the feeding pipe; A feeding reset assembly is disposed on one side of the feeding tube; The feeding and pushing assembly includes an extension tube disposed at the end of the feeding tube. The extension tube has a feeding port on its side wall and a driving port on its side wall. The extension tube has a driving frame on its outer side wall, a rotating shaft on the driving frame, a rotating disk on the rotating shaft, and a striking block on the rotating disk. The extension tube has a pushing plate on its inner side wall, and the striking block is in contact with the pushing plate.
[0005] As a further technical solution, one end of the feeding pipe is provided with a feeding port, the feeding pipe has a spiral structure, and the lower end face of the support frame is provided with a support plate.
[0006] As a further technical solution, the feeding reset assembly includes a movable block, which is disposed on the inner side wall of the extension tube. The movable block is connected to the pusher plate by a pin. A drive column is disposed on the upper end face of the pusher plate. A reset frame is disposed on the drive column. A reset spring is disposed on the reset frame.
[0007] As a further technical solution, the reset spring is disposed on the outer side wall of the extension tube, and a reset plate is disposed on the lower end face of the reset frame.
[0008] As a further technical solution, a discharge hood is provided on the side wall of the feeding port, and the discharge hood is matched with the width of the feeding port.
[0009] As a further technical solution, the number of striking blocks is several, and the multiple striking blocks are evenly distributed on the side wall of the rotating disk, with the striking blocks embedded inside the drive port.
[0010] As a further technical solution, the cross-section of the feeding pipe is an inverted gate-shaped structure, and a feed pipe is provided at one end of the feeding pipe.
[0011] As a further technical solution, the drive column and the pusher plate are movably connected by a pin, and the reset spring and the reset plate are fixedly connected.
[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the feeding mechanism of the nail-packing machine adopts a unique design of a feeding push assembly and a feeding reset assembly.

[0021] like Figures 1-5 As shown, it illustrates a feeding mechanism for a nail-stacking machine according to this disclosure, comprising: Feeding pipe 1, with a support frame 2 provided on the lower end face of feeding pipe 1; Feeding push component 3 is located at the end of feeding pipe 1; Feeding reset assembly 4 is disposed on one side of feeding pipe 1; The feeding push assembly 3 includes an extension tube 3-1, which is located at the end of the feeding tube 1. The side wall of the extension tube 3-1 is provided with a feeding port 3-2 and a drive port 3-3. The outer side wall of the extension tube 3-1 is provided with a drive frame 3-4, a rotation shaft 3-5 is provided on the drive frame 3-4, a rotating disk 3-6 is provided on the rotation shaft 3-5, and a striking block 3-7 is provided on the rotating disk 3-6. The inner side wall of the extension tube 3-1 is provided with a push plate 3-8, and the striking block 3-7 is in contact with the push plate 3-8. The feeding reset assembly 4 includes a movable block 4-1, which is disposed on the inner side wall of the extension tube 3-1. The movable block 4-1 is connected to the push plate 3-8 by a pin. The upper end face of the push plate 3-8 is provided with a drive column 4-2, and a reset frame 4-3 is provided on the drive column 4-2. A reset spring 4-4 is provided on the reset frame 4-3. In some examples, an extension tube 3-1 is fabricated using tubing of appropriate specifications. A feeding port 3-2 and a drive port 3-3 are precisely machined on the side wall of the extension tube 3-1. The position and size of the feeding port 3-2 must ensure that the pins can smoothly enter the subsequent processing stages. The size of the drive port 3-3 must be compatible with the striking block 3-7 to ensure that the striking block 3-7 can function properly. The drive frame 3-4 is fixedly installed on the outer side wall of the extension tube 3-1, ensuring accurate installation. A rotating shaft 3-5 is installed on the drive frame 3-4, ensuring that the rotating shaft 3-5 can rotate flexibly. A rotating disk 3-6 is installed on the rotating shaft 3-5, and the rotating disk 3-6 is secured by a key connection or other suitable method. Rotates synchronously with the spindle 3-5; multiple striking blocks 3-7 are evenly distributed on the side wall of the rotating disk 3-6, the number of striking blocks 3-7 is determined according to actual needs, and during installation, it is necessary to ensure that the striking blocks 3-7 are embedded inside the drive port 3-3 and can move freely within the drive port 3-3, while ensuring good contact between the striking blocks 3-7 and the pusher plate 3-8; the pusher plate 3-8 is installed on the inner side wall of the extension tube 3-1, ensuring that the pusher plate 3-8 can slide smoothly within the extension tube 3-1, while ensuring that the striking blocks 3-7 can effectively push the pusher plate 3-8; the contact surface between the pusher plate 3-8 and the striking blocks 3-7 can be appropriately surface-treated, such as polished smooth, to reduce frictional resistance; A movable block 4-1 is installed on the inner wall of the extension tube 3-1. The movable block 4-1 is connected to the push plate 3-8 by a pin, ensuring that the movable block 4-1 and the push plate 3-8 can rotate flexibly after connection, providing the necessary degree of freedom for feeding and resetting. A drive column 4-2 is installed on the upper end face of the push plate 3-8, using a pin-connected method to ensure that the drive column 4-2 can rotate flexibly relative to the push plate 3-8. A reset frame 4-3 is installed on the drive column 4-2, ensuring that the reset frame 4-3 is firmly installed. like Figures 1-5 As shown, in this embodiment, one end of the feeding pipe 1 is provided with a feeding port 3-9, the feeding pipe 1 has a spiral structure, and the lower end face of the support frame 2 is provided with a support plate 3-10; In some examples, a feed port 3-9 is precisely opened at one end of the feed tube 1 to ensure that the size of the feed port 3-9 is compatible with the specifications of the pin pack, so that the pin pack can smoothly enter the feed tube 1; For example, such as Figure 5 As shown, the reset spring 4-4 is provided on the outer side wall of the extension tube 3-1, and the reset plate 4-5 is provided on the lower end face of the reset frame 4-3. In some examples, the reset spring 4-4 is installed on the outer wall of the extension tube 3-1. One end of the reset spring 4-4 is fixedly connected to the extension tube 3-1, and the other end is fixedly connected to the reset plate 4-5 on the reset frame 4-3. During installation, the preload of the reset spring 4-4 should be adjusted to ensure that the feeding reset assembly 4 can work normally and can reset in time after the pusher plate 3-8 completes the feeding action. For example, such as Figure 1 As shown, a discharge hood 5 is provided on the side wall of the feeding port 3-2, and the width of the discharge hood 5 matches that of the feeding port 3-2; In some examples, a discharge cover 5 is made according to the size of the feeding port 3-2, so that the width of the discharge cover 5 is strictly matched with that of the feeding port 3-2. The discharge cover 5 is fixed to the side wall of the feeding port 3-2 by welding or bolting to ensure a tight connection and prevent the pins from getting stuck or falling off during the discharge process. For example, such as Figure 2 As shown, there are several striking blocks 3-7, and multiple striking blocks 3-7 are evenly distributed on the side wall of the rotating disk 3-6. The striking blocks 3-7 are embedded inside the drive port 3-3. For example, such as Figure 1 As shown, the cross-section of the feeding pipe 1 is an inverted gate-shaped structure, and a feed pipe 6 is provided at one end of the feeding pipe 1. In some examples, a feed pipe 6 is welded to one end of the feed pipe 1, and a support frame 2 is welded to the other end. A support plate 3-10 is welded to the lower end face of the support frame 2. When welding, it is necessary to ensure that the connection is firm to prevent loosening in subsequent use. For example, such as Figure 5 As shown, the drive column 4-2 and the pusher plate 3-8 are movably connected by a pin, and the reset spring 4-4 and the reset plate 4-5 are fixedly connected. In some examples, the shape of the feed pipe 1, which has an inverted gate-shaped cross-section, is completed through processes such as cutting and welding. When in use, the feeding mechanism of the nail-packing machine can be divided into three main stages: feeding preparation, nail pushing, and resetting to prepare for the next cycle; the entire mechanism achieves continuous and stable feeding of nails through the coordinated operation of its components. The pins enter the spiral or inverted gate-shaped feeding pipe 1 through the feeding pipe 6; the special structural design of the feeding pipe 1 makes the pins arranged in an orderly manner along the pipe and move towards the extension pipe 3-1 under the action of gravity and subsequent pushing force; at this time, the feeding reset component 4 is in the initial state, the reset spring 4-4 is in the natural or pre-tightened state, and the push plate 3-8 is located in the starting position inside the extension pipe 3-1; When the nail bar moves to the feeding port 3-2, the rotating shaft 3-5 on the drive frame 3-4 drives the rotating disk 3-6 to start rotating; the evenly distributed striking blocks 3-7 on the rotating disk 3-6 make circular motion as the rotating disk 3-6 rotates; when the striking blocks 3-7 rotate to the drive port 3-3, they will be embedded in the drive port 3-3 and contact the pusher plate 3-8, pushing the pusher plate 3-8 to slide forward in the extension tube 3-1; the sliding of the pusher plate 3-8 will push the nail bar located at the feeding port 3-2 out of the extension tube 3-1, and enter the next processing stage of the nail bar machine through the discharge hood 5; As the striking block 3-7 continues to rotate away from the drive port 3-3 along with the rotating disk 3-6, the pusher plate 3-8 loses the pushing force of the striking block 3-7. At this time, the feeding reset assembly 4 comes into play, and the elastic restoring force of the reset spring 4-4 is transmitted to the pusher plate 3-8 through the reset frame 4-3 and the drive column 4-2, causing the pusher plate 3-8 to quickly slide backward and reset to the initial position. At the same time, since the movable block 4-1 and the pusher plate 3-8 are connected by a pin, the movement flexibility of the pusher plate 3-8 during the reset process is ensured, and jamming is avoided. After the pusher plate 3-8 is reset, the feeding mechanism completes one working cycle and waits for the next row of nails to move to the feeding port 3-2 position to start the next round of feeding action. The innovation of this working principle lies in converting rotational motion into linear pushing motion. The intermittent pushing of the nails is achieved through the periodic contact and separation of the striking block 3-7 and the pusher plate 3-8. Compared with the traditional vibratory feeder method, this working principle has the following advantages: Precise control: By adjusting the rotation speed of the rotary disk 3-6 and the distribution number of the striking blocks 3-7, the movement frequency and stroke of the pusher plate 3-8 can be precisely controlled, thereby achieving precise control of the push speed and distance of the nail pack and meeting the requirements of different production processes for nail pack feeding; Stable and reliable: The mechanical transmission method makes the feeding process more stable and reliable, reducing the instability of nail conveying caused by vibration or other external factors, reducing equipment failure rate and improving production efficiency; High efficiency and energy saving: This working principle does not require a continuous supply of high-intensity vibration energy. The feeding of the nail pack can be achieved simply by rotating the rotating disk 3-6, which has higher energy utilization efficiency and meets the requirements of modern industry for energy conservation and emission reduction.
