Technical Field
[0001] This invention relates to the field of automatic feeding, and more particularly to an automatic feeding mechanism that improves safety. Background Technology
[0002] An existing patent (publication number: CN114620451B) proposes an automatic feeding mechanism for metal bars, including a feeding seat, a conveying device, and a feeding device. The upper surface of the feeding seat is inclined, and the conveying device includes a component to be fed and a conveying component. However, this device "drives the drive sprocket to rotate, and the drive sprocket drives the drive chain to rotate." When the drive chain moves the bar body forward, the bar may fall due to external impact, thus affecting the stability and safety of the bar feeding. Summary of the Invention
[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an automatic feeding mechanism that improves safety by providing a permanent magnet inside the part positioning column that continuously attracts rod-shaped parts during the automatic feeding process, keeping the rod-shaped parts fixed during feeding and preventing them from falling off due to external impacts.
[0004] The objective of this invention is achieved through the following technical solution: An automatic feeding mechanism with improved safety includes a main support frame, a partition plate, a side adjusting cylinder, a linkage pulley, and a linkage transmission belt. The main support frame has a bottom hollow frame, and both sides of the main support frame have bearing shaft connecting grooves and side cylinder bearing rods. The side cylinder bearing rods are located at the top of the bearing shaft connecting grooves. A main bearing roller is installed inside the main support frame, and the surface of the main bearing roller has screw clearance grooves. Multiple sets of screw clearance grooves are evenly arranged on the surface of the main bearing roller. Both sides of the main bearing roller have bearing shaft connecting shafts, which are rotatably connected to the bearing shaft connecting grooves. The side of the bearing shaft connecting shaft has a pulley connecting shaft, which is connected to the linkage pulley. Two adjacent linkage pulleys are connected by a linkage transmission belt. The side of the main support frame has a feeding motor mounting platform, which corresponds to the bearing shaft connecting groove located at the end.
[0005] The feeding motor is inserted into and fixed inside the feeding motor mounting platform. The transmission shaft of the feeding motor is fixedly connected to the corresponding bearing shaft connecting shaft. The side of the main support frame has a discharge plate connecting platform, which corresponds to the position of the feeding motor. The end of the discharge plate connecting platform has a discharge plate. The part conveyor belt is sleeved on the outside of the main bearing roller array group. The surface of the part conveyor belt has a bearing ring connecting groove, which corresponds to the position of the screw clearance groove. The positioning plate bearing ring is adapted to the bearing ring connecting groove and is connected to the bearing ring connecting groove. The positioning plate bearing ring is inserted into the bearing ring connecting groove. A positioning bearing plate is provided at the top of the part conveyor belt. The bottom of the positioning bearing plate has a positioning plate connecting screw. The positioning plate connecting screw passes through the positioning plate bearing ring and is threadedly connected to the positioning plate mounting nut.
[0006] The positioning plate mounting nut is pressed against the bottom of the positioning plate bearing ring. The side of the positioning bearing plate has a side positioning post connecting cylinder, and the top of the positioning bearing plate is provided with a part positioning post. The side of the part positioning post facing the side positioning post connecting cylinder has a side positioning post. The side positioning post is adapted to the side positioning post connecting cylinder and is connected to the side positioning post connecting cylinder. The side positioning post slides inside the side positioning post connecting cylinder. The side positioning post and the side positioning post connecting cylinder are connected by a spring. The permanent magnet is adapted to the part positioning post and is connected to the part positioning post. The permanent magnet is inserted into the part positioning post and fixed. The top of the part conveyor belt is connected to a rod-shaped part, which is pressed against the side of the part positioning post.
[0007] Beneficial effects: 1. During the automatic feeding process of this invention, the permanent magnet inside the part positioning column continuously attracts the rod-shaped part, keeping the rod-shaped part fixed during the feeding process and preventing it from falling off due to external impact, thus further increasing the feeding safety of this device.
[0008] 2. In this invention, the side positioning post and the side positioning post connecting cylinder are connected by a spring. During the process of the permanent magnet attracting the rod-shaped part, when the rod-shaped part collides with the part positioning post, the spring can provide partial buffering to avoid excessive force on the positioning plate connecting screw and the positioning plate bearing ring, which would damage the bearing ring connecting groove and ensure the service life of the part conveyor belt.
[0009] 3. In this invention, the side limiting band continuously presses against the side of the rod-shaped part to keep the rod-shaped part centered. At the same time, the limiting roller and the limiting roller connecting shaft are rotatably connected, so that the side of the rod-shaped part and the side limiting band will not continuously generate sliding friction, thereby reducing the energy consumption when feeding the rod-shaped part.
[0010] 4. The partition plate of the present invention can slide inside the partition plate support column, and the side adjustment cylinder can adjust the position of the side limit platform, so that the device can perform feeding operations on rod-shaped parts of various lengths and diameters, increasing the adaptability of the device.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: An automatic feeding mechanism with improved safety includes a main support frame 1, a partition plate 3, a side adjusting cylinder 7, a linkage pulley 8, and a linkage transmission belt 9. The main support frame 1 has a bottom hollow frame 2 at its bottom. The main support frame 1 has a bearing shaft connecting groove 34 and a side cylinder bearing rod 5 on both sides. The side cylinder bearing rod 5 is located at the top of the bearing shaft connecting groove 34. A main bearing roller 10 is provided inside the main support frame 1. The surface of the main bearing roller 10 has a screw clearance groove 11. Multiple sets of screw clearance grooves 11 are evenly arranged on the surface of the main bearing roller 10. The main bearing roller 10 has a bearing shaft connecting shaft 35 on both sides. The bearing shaft connecting shaft 35 is rotatably connected to the bearing shaft connecting groove 34. The side of the bearing shaft connecting shaft 35 has a pulley connecting shaft 29. The pulley connecting shaft 29 is connected to the linkage pulley 8. Two adjacent linkage pulleys 8 are connected by the linkage transmission belt 9. The side of the main support frame 1 has a feeding motor mounting platform 32, which corresponds to the bearing shaft connecting groove 34 located at the end.
[0020] Example 2: The feeding motor 33 of the present invention is inserted into the feeding motor mounting platform 32 and fixed. The transmission shaft of the feeding motor 33 is fixedly connected to the bearing shaft connecting shaft 35 at the corresponding position. The side of the main support frame 1 has a discharge plate connecting platform 30, which corresponds to the position of the feeding motor 33. The end of the discharge plate connecting platform 30 has a discharge plate 31. The part conveyor belt 12 is sleeved on the outside of the main bearing roller 10 array group. The surface of the part conveyor belt 12 has a bearing ring connecting groove 13, which corresponds to the position of the screw clearance groove 11. The positioning plate bearing ring 14 is adapted to the bearing ring connecting groove 13 and is connected to the bearing ring connecting groove 13. The positioning plate bearing ring 14 is inserted into the bearing ring connecting groove 13. The top of the part conveyor belt 12 is provided with a positioning bearing plate 18. The bottom of the positioning bearing plate 18 has a positioning plate connecting screw 15, which passes through the positioning plate bearing ring 14 and is threadedly connected to the positioning plate mounting nut 16.
[0021] Example 3: The positioning plate mounting nut 16 of the present invention is pressed against the bottom of the positioning plate bearing ring 14. The side of the positioning bearing plate 18 has a side positioning post connecting cylinder 19, and the top of the positioning bearing plate 18 is provided with a part positioning post 21. The side of the part positioning post 21 facing the side positioning post connecting cylinder 19 has a side positioning post 20. The side positioning post 20 is adapted to the side positioning post connecting cylinder 19 and is connected to the side positioning post connecting cylinder 19. The side positioning post 20 slides inside the side positioning post connecting cylinder 19. The side positioning post 20 and the side positioning post connecting cylinder 19 are connected by a spring. The inside of the side positioning post 20 and the side positioning post connecting cylinder 19 are connected by a spring. During the process of the permanent magnet 22 attracting the rod-shaped part 17, the rod-shaped part 17 collides with the part positioning post 21. Upon impact, the spring provides partial cushioning to prevent excessive force on the positioning plate connecting screw 15 and the positioning plate bearing ring 14, thus protecting the bearing ring connecting groove 13 and ensuring the service life of the parts conveyor belt 12. The permanent magnet 22 is compatible with the parts positioning post 21 and is connected to the parts positioning post 21. The permanent magnet 22 is inserted into the parts positioning post 21 for fixation. During automatic feeding, the permanent magnet 22 inside the parts positioning post 21 continuously attracts the rod-shaped parts 17, keeping the rod-shaped parts 17 fixed during feeding and preventing them from falling due to external impact, further increasing the feeding safety of this device. The top of the parts conveyor belt 12 is connected to the rod-shaped parts 17, which are pressed against the side of the parts positioning post 21.
[0022] Example 4: The side cylinder bearing rod 5 of the present invention has a side cylinder mounting groove 6 at its top. The side adjusting cylinder 7 is inserted into the side cylinder mounting groove 6 and fixed. A side limiting platform 23 is provided on the side of the side cylinder mounting groove 6 facing the part conveyor belt 12. The telescopic rod of the side adjusting cylinder 7 is fixedly connected to the side limiting platform 23. The side limiting platform 23 has a limiting roller connecting shaft 25 on the side facing the part conveyor belt 12. The limiting roller connecting shaft 25 is rotatably connected to the limiting roller 24. The side limiting band 28 is sleeved on the outside of the array of limiting rollers 24, and the side limiting... The belt 28 continuously presses against the side of the rod-shaped part 17 to keep the rod-shaped part 17 centered. At the same time, the limiting roller 24 is rotatably connected to the limiting roller connecting shaft 25, so that the side of the rod-shaped part 17 and the side limiting belt 28 will not continuously generate sliding friction, reducing the energy consumption when feeding the rod-shaped part 17. The side limiting belt 28 contacts the side of the rod-shaped part 17. The main support frame 1 has partition plate bearing columns 4 on both sides. The partition plate bearing columns 4 are located on the side of the side cylinder bearing rod 5 array group. The partition plate 3 is adapted to the partition plate bearing columns 4.
[0023] Example 5: The partition plate 3 of this invention is connected to the partition plate support column 4. The partition plate 3 is inserted into the partition plate support column 4 and can slide inside the partition plate support column 4. The side adjustment cylinder 7 can adjust the position of the side limiting platform 23, so that this device can perform feeding operations on rod-shaped parts 17 of various lengths and diameters, increasing the adaptability of this device. The partition plate 3 is located on the upper part of the array of part positioning columns 21. The side of the partition plate support column 4 has a positioning screw mounting platform 26, which is threadedly connected to the partition plate positioning screw 27. The partition plate positioning screw 27 is pressed against the side of the partition plate 3. This invention realizes the complete conversion of sliding friction to rolling friction, so that there is no continuous sliding friction between the rod-shaped parts and the side limiting belt when the rod-shaped parts move forward. This not only avoids scratch damage to the side of the rod-shaped parts, but also significantly reduces the resistance of the part conveyor belt to drive the rod-shaped parts forward, significantly reducing the operating energy consumption of the feeding motor, and realizing energy-saving operation of the equipment. The energy-saving effect is particularly prominent in large-volume, continuous feeding operations.
[0024] Example 6: The installation steps of the automatic feeding mechanism for improving safety according to the present invention are as follows: Rotarily connect the bearing shaft connecting shaft 35 of the main bearing roller 10 to the bearing shaft connecting groove 34 of the main support frame 1; fix the pulley connecting shaft 29 of the main bearing roller 10 to the linkage pulley 8; connect two adjacent linkage pulleys 8 to the linkage transmission belt 9; fit the part conveyor belt 12 around the outside of the main bearing roller 10 array group; insert the positioning plate bearing ring 14 into the bearing ring connecting groove 13 of the part conveyor belt 12; thread the positioning plate connecting screw 15 of the positioning bearing plate 18 through the positioning plate bearing ring 14 and connect it to the positioning plate mounting nut 16, so that the positioning plate mounting nut 16 is pressed against the bottom of the positioning plate bearing ring 14; insert the side positioning post 20 of the part positioning post 21 into the positioning plate bearing ring 14. The side positioning column connecting cylinder 19 of the bearing plate 18 is used to connect the side positioning column 20 and the side positioning column connecting cylinder 19 by a spring. The permanent magnet 22 is inserted into the part positioning column 21 and fixed. The partition plate 3 is inserted into the partition plate bearing column 4 of the main support frame 1. The partition plate positioning screw 27 is threadedly connected to the positioning screw mounting platform 26 of the partition plate bearing column 4, so that the partition plate positioning screw 27 is pressed against the side of the partition plate 3. The side adjusting cylinder 7 is inserted into the side cylinder mounting groove 6 of the main support frame 1. The telescopic rod of the side adjusting cylinder 7 is fixedly connected to the side limiting platform 23. The limiting roller connecting shaft 25 of the side limiting platform 23 is rotatably connected to the limiting roller 24. The side limiting band 28 is sleeved on the outside of the array of limiting rollers 24. The installation of this device is completed. This invention not only avoids damage such as surface bumps and deformation of rod-shaped parts due to hard collisions, but also prevents the positioning plate connecting screw and the positioning plate bearing ring from being squeezed, worn or even cracked by excessive instantaneous force on the bearing ring connecting groove of the parts conveyor belt. It unexpectedly protects the structural integrity of the core components of the conveyor, greatly extends the service life of the parts conveyor belt, and reduces the frequency of replacement of vulnerable parts and the cost of use.
[0025] This invention enables the orderly feeding of rod-shaped parts. The adjustable structure of the partition plate can precisely control the width of the feeding channel according to the diameter of the rod-shaped parts, avoiding the stacking and jamming of multiple rod-shaped parts. Combined with the centering positioning of the side limiting platform, each rod-shaped part can accurately correspond and engage with the part positioning post and permanent magnet, completely solving the feeding interruption problem caused by the stacking and jamming of multiple parts in traditional feeding mechanisms. While improving adaptability, it also improves the continuity and orderliness of feeding, resulting in a significant increase in feeding efficiency compared to traditional devices. Because the part conveyor belt moves at a constant speed without any jerking, there is no relative shaking or displacement between the rod-shaped parts and the part positioning post and permanent magnet. This avoids the problems of permanent magnet engagement failure and part loosening caused by uneven conveyor belt speed. While ensuring uniform feeding speed, it further improves the safety of the feeding process, making the anti-drop effect several times better than traditional asynchronous drive devices, making it particularly suitable for high-speed, continuous feeding operations. The collaborative design and mutual linkage of the various structures in this invention result in additional benefits from the superposition of the functions of each component. It not only exceeds the single design goal of preventing rod-shaped parts from falling and improving the safety of feeding, but also optimizes the performance of the device from multiple dimensions such as service life, energy consumption, efficiency, maintenance, and adaptability. Compared with traditional automatic feeding mechanisms, this invention has more comprehensive technical advantages and higher practical application value.
[0026] Example 7: An operational method for an automated feeding mechanism with improved safety: The feeding motor 33 drives the corresponding main bearing roller 10 to rotate. All main bearing rollers 10 are synchronously linked through the linkage pulley 8 and the linkage transmission belt 9, causing the parts conveyor belt 12 to move forward continuously, completing the automated feeding. Then, the rod-shaped part 17 is placed on the side of the partition plate 3 opposite to the forward direction of the parts conveyor belt 12. After the rod-shaped part 17 is placed, the part positioning post 21 and the permanent magnet 22 connector attract the rod-shaped part 17, causing the part positioning post 21 and the permanent magnet 22 connector to pull the rod-shaped part 17. As the process continues, the stacked rod-shaped parts 17 will be blocked by the partition plate 3 until each part positioning post 21 and permanent magnet 22 connector pulls a rod-shaped part 17 through the partition plate 3. After the rod-shaped part 17 passes through the partition plate 3, the side adjusting cylinder 7 drives the side limiting platform 23 to press against the rod-shaped part 17 to center it. Then the side adjusting cylinder 7 drives the side limiting platform 23 to reset. When a new rod-shaped part 17 passes through the partition plate 3, the side limiting platform 23 presses against the rod-shaped part 17 again to center it, ensuring the accuracy and stability of the feeding.
[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
