Description

Technical Field

[0001] This invention relates to the field of valve manufacturing technology, and more specifically to a feeding device. Background Technology

[0002] Valve is mainly used to start and close the intake and exhaust manifolds during engine operation, controlling the entry of fuel mixture or air and the discharge of exhaust gases. In actual production, manual feeding of each valve is inefficient and labor-intensive for workers. Therefore, some production processes use guide rails to feed valves. However, operators still need to install the valves to be processed one by one onto the guide rails. Moreover, during the installation process, valves that are not placed neatly need to be straightened before they can be installed onto the guide rails, resulting in high labor intensity, high labor costs, and low valve production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a feeding device that can effectively solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A feeding device includes two sets of guide rail assemblies arranged in a vertical direction, each set of the guide rail assemblies including two inclined feeding guide rails arranged side by side; The system includes a feeding assembly for feeding materials to the guide rail assembly. The feeding assembly includes a material holding shell with a first base plate at its bottom. The material holding shell has a cylindrical material holding cavity inside. Cylindrical track partitions with progressively increasing diameters are arranged sequentially from the center to the outside of the material holding cavity. The bottom of the track partitions is connected to the first base plate. A material storage track is formed between two adjacent track partitions. Each material storage track has a first discharge port. The material holding shell has a second discharge port. The first discharge port and the second discharge port are connected through a discharge channel. The system includes a feeding assembly for sequentially feeding valves arranged on the guide rail assembly. The feeding assembly includes a cylindrical feeding cylinder with a feeding chamber inside. A feeding port communicating with the feeding chamber is opened on the side wall of the feeding cylinder. The feeding cylinder is located below the upper guide rail assembly. An arc-shaped mounting groove is opened on the adjacent side of the two feeding guide rails in the lower guide rail assembly. The feeding cylinder performs one feeding action for each rotation in the arc-shaped mounting groove.

[0005] Preferably, the width of the feed port is equal to the distance between the two feeding guide rails in each group of guide rail assemblies, and the bottom of the feed cylinder is connected to a drive motor that provides power for the rotation of the feed cylinder.

[0006] Preferably, two guide plates are provided on one side of the material holding shell located at the second discharge port. The guide plates are connected to the outer wall of the material holding shell, and the two guide plates form a transition channel. The size of the opening at one end of the transition channel is equal to the size of the second discharge port, and the size of the opening at the other end is equal to the distance between the two feeding guide rails in each set of guide rail assemblies. The bottom of the guide plates is connected to the second base plate.

[0007] Preferably, a limiting end cap is provided above the material holding shell, the material holding shell extends out of the outer side of the first base plate, and a third screw is distributed in a circular array at the bottom of the limiting end cap. The lower end of the third screw passes through a first mounting hole opened on the first base plate, and a first nut is threadedly connected to the upper and lower sides of the first base plate, respectively.

[0008] Preferably, the system further includes a fixed baffle for sealing the transition channel. The fixed baffle has a first boss at its upper end, and a threaded post is connected to the upper end face of the first boss. The limiting end cover has a second boss, and a second mounting hole is provided on the second boss. The upper end of the threaded post passes through the second mounting hole and is threadedly connected to a second nut.

[0009] Preferably, the limiting end cap is made of transparent material, a gap is provided between the limiting end cap and the material holding shell, and a protective sleeve made of rubber material is installed at the lower end of the third screw.

[0010] Preferably, each of the two feeding guide rails in each guide rail assembly is provided with a first fixing post on its outer side. A first positioning block is provided on one side of the first fixing post. A first waist-shaped hole is provided on the first positioning block. One end of the fastening bolt passes through the first waist-shaped hole and is connected to the threaded connection hole opened on the end face of the first fixing post. The bottom of the first positioning block is connected to the first fixing block. The two first fixing blocks are connected by a second screw.

[0011] Preferably, a first screw hole is provided on the side wall of the feeding cylinder, and a first screw is threadedly connected to the first screw hole. One end of the first screw is connected to a first limiting plate, and the other end does not extend out of the first screw hole.

[0012] Preferably, the valve stem is attached to two feed rails in each set of the guide rail assembly on both sides, and the valve head is supported on the two upper feed rails and moves along the feed rails.

[0013] Preferably, the upper ends of the two feeding guides in each group of guide rail assemblies open outwards to form inlets.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Arrange the valves to be processed in the storage rails within the material holding cavity. Install the limiting end cap on top of the material holding housing. Adjust the gap between the limiting end cap and the material holding housing using the third screw. When placing the valves into the guide rail assembly, set one end outlet of the transition channel to the inlet of the guide rail assembly, so that the valves to be processed in the storage rails are fed between the two feeding guide rails of the guide rail assembly through the first outlet, the discharge channel, the second outlet, and the transition channel. The gap between the first outlet and the second outlet is greater than twice the valve stem diameter to reduce the simultaneous feeding of valves from both sides in the same storage rail. If the valve becomes blocked at the first discharge port, it can be gently shaken during the feeding process to facilitate smooth entry of the valve into the transition channel via the first discharge port, the discharge channel, and the second discharge port. Since the outlet gap at the end of the transition channel near the second discharge port is larger than the outlet gap at the end near the feeding guide rail, the valve enters the guide rail assembly sequentially in the transition channel. This invention eliminates the need for manual placement of each valve between the two feeding guide rails in the guide rail assembly, thus avoiding the need to adjust the valve's position before placing it between the two feeding guide rails, greatly improving valve production efficiency. 2. Before feeding the guide rail assembly, the operator can place the valve to be processed in the storage rail in the material holding cavity in advance, and seal the transition channel by fixing the baffle. The threaded post on the upper surface of the first boss passes through the second mounting hole 24 on the second boss and is threadedly connected to the second nut. During the processing of the valve in the guide rail assembly, the next valve to be processed needs to be fed after the previous processing cycle is completed. When feeding, the valve enters the feeding chamber through the feeding port. After each processing cycle is completed, the feeding cylinder rotates until the feeding port rotates 180 degrees to the other side, and then the valve in the feeding chamber is discharged from the feeding port. Similarly, the valves in the guide rail assembly are processed one by one. The volume of the feeding chamber can be adjusted so that the feeding chamber can only accommodate one valve. When producing valves of different specifications, the position of the first limiting plate in the feeding chamber can also be adjusted by setting the length of the first screw so that the feeding chamber can only accommodate one valve.

Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-7 As shown, a feeding device includes two sets of guide rail assemblies arranged in a vertical direction, each set of the guide rail assemblies including two inclined and side-by-side feeding guide rails 1; The two sets of guide rail assemblies arranged vertically are the upper guide rail assembly and the lower guide rail assembly. The valve is simultaneously placed between the two feeding guide rails 1 in the two sets of guide rail assemblies, and the valve to be processed moves along the feeding guide rail 1. The system includes a feeding assembly for feeding materials to the guide rail assembly. The feeding assembly includes a material holding shell 2, a first base plate 3 at the bottom of the material holding shell 2, and a cylindrical material holding cavity inside the material holding shell 2. Cylindrical track partitions 4 with progressively increasing diameters are arranged sequentially from the center to the outside of the material holding cavity. The bottom of the track partitions 4 is connected to the first base plate 3. A storage track 5 is formed between two adjacent track partitions 4. A first discharge port 6 is provided on each storage track 5. A second discharge port 7 is provided on the material holding shell 2. The first discharge port 6 and the second discharge port 7 are connected through a discharge channel 8. The gap of the storage track 5 is sufficient to allow the valves to be distributed along the storage track 5. When feeding, the valves move along the storage track 5. The valves on both sides of the same storage track 5 are discharged from the first discharge port 6 through the discharge channel 8 and the second discharge port 7. The system includes a feeding assembly for sequentially feeding valves arranged on the guide rail assembly. The feeding assembly includes a cylindrical feeding cylinder 9 with a feeding chamber 10 inside. A feeding port 11 communicating with the feeding chamber 10 is opened on the side wall of the feeding cylinder 9. The feeding cylinder 9 is located below the upper guide rail assembly. An arc-shaped mounting groove 12 is opened on the adjacent side of the two feeding guide rails 1 in the lower guide rail assembly. The feeding cylinder 9 performs one feeding action for each revolution in the arc-shaped mounting groove 12. The valves distributed on the feeding guide rail 1 enter the feeding chamber 10 through the feeding port 11 on the feeding cylinder 9. Due to the volume limitation of the feeding chamber 10, other valves cannot enter the feeding chamber 10. After the feeding cylinder 9 rotates 180 degrees, the valves in the feeding chamber 10 are discharged from the feeding port 11 again. After the feeding cylinder 9 rotates 180 degrees again, the next valve to be processed enters the feeding chamber 10. Similarly, the feeding action of the valves is completed one by one. The width of the feed port 11 is equal to the distance between the two feeding guide rails 1 in each group of guide rail assemblies. The bottom of the feed cylinder 9 is connected to a drive motor that provides power for the rotation of the feed cylinder 9. The rotation cycle of the feed cylinder 9 is controlled by the drive motor, thereby realizing the periodic feeding action of the valves on the feeding guide rail 1. The drive motor can be installed on the fixed frame through the motor mounting bracket according to the installation requirements.

[0018] Two guide plates 13 are provided on one side of the second discharge port 7 on the material holding shell 2. The guide plates 13 are connected to the outer wall of the material holding shell 2. The two guide plates 13 form a transition channel 14. The size of the opening at one end of the transition channel 14 is equal to the size of the second discharge port 7, and the size of the opening at the other end is equal to the distance between the two feeding guide rails 1 in each set of guide rail assemblies. The bottom of the guide plate 13 is connected to the second bottom plate 15. The valves in the storage track 5 enter the transition channel 14 through the first discharge port 6, the discharge channel 8 and the second discharge port 7. The outlet gap at the end of the transition channel 14 near the feeding guide rail 1 allows only one valve to pass through and enter the feeding guide rail 1 at a time. A limiting end cap 16 is provided above the material holding shell 2. The material holding shell 2 extends out of the outer side of the first base plate 3. The bottom of the limiting end cap 16 is provided with a third screw 17 arranged in a circular array. The lower end of the third screw 17 passes through the first mounting hole 18 opened on the first base plate 3. The upper and lower sides of the first base plate 3 are respectively threaded with a first nut 19. When installing the limiting end cover 16, simply install the third screw 17 at the bottom of the limiting end cover 16 into the first mounting hole 18 on the first base plate 3 and fix the limiting end cover 16 with the first nut 19. Adjust the gap between the material holding housing 2 and the limiting end cover 16 so that the valve can move in the material storage track 5.

[0019] It also includes a fixed baffle 20 for sealing the transition channel 14. The upper end of the fixed baffle 20 is provided with a first boss 21. The upper end face of the first boss 21 is connected to a threaded post 22. The limiting end cover 16 is provided with a second boss 23. The second boss 23 is provided with a second mounting hole 24. The upper end of the threaded post 22 passes through the second mounting hole 24 and is threadedly connected to the second nut 25. The limiting end cap 16 is made of transparent material, and a gap is provided between the limiting end cap 16 and the material holding shell 2. The lower end of the third screw is equipped with a protective sleeve 33 made of rubber material; the protective sleeve 33 is made of soft rubber material to prevent the third screw from contacting the operator. The limiting end cap 16 is made of transparent material to facilitate observation of the number of valves and the feeding status of the valves in the material holding shell 2 through the limiting end cap 16; the feeding rate can be adjusted by appropriately tilting and shaking the material holding shell 2. Each of the two feeding guide rails 1 in each guide rail assembly is provided with a first fixing post 26 on the outer side. A first positioning block 27 is provided on one side of the first fixing post 26. A first waist-shaped hole 28 is provided on the first positioning block 27. One end of the fastening bolt 29 passes through the first waist-shaped hole 28 and is connected to the threaded connection hole on the end face of the first fixing post 26. The bottom of the first positioning block 27 is connected to the first fixing block 34. The two first fixing blocks 34 are connected by a second screw 30. By adjusting the spacing between the first fixed posts 26 on the two sets of guide rail assemblies, the distance between the two sets of guide rail assemblies can be adjusted, so that the valve can stably supply material under the limiting action of the two sets of guide rail assemblies; the second screw 30 can be installed on the fixed frame as needed for installation. The side wall of the feeding cylinder 9 is provided with a first screw hole 31, and a first screw is threadedly connected to the first screw hole 31. One end of the first screw is connected to the first limiting plate 32, and the other end does not extend out of the first screw hole 31. When processing valves of different specifications, the position of the first limiting plate 32 in the feeding chamber 10 is adjusted by adjusting the length of the first screw to ensure that only one valve is accommodated in the feeding chamber 10. The sequential feeding action is completed with each rotation. The valve stem is attached to two feed rails 1 in each group of the guide rail assembly on both sides, and the valve head is supported on the two upper feed rails and moves along the feed rails 1. In each set of guide rail assemblies, the upper ends of the two feeding guide rails 1 open outwards to form a feeding port.

[0020] Arrange the valves to be processed in the storage track 5 within the material holding cavity. Install the limiting end cap 16 above the material holding housing 2. Adjust the gap between the limiting end cap 16 and the material holding housing 2 using the third screw. When placing the valves into the guide rail assembly, set one end outlet of the transition channel 14 at the inlet of the guide rail assembly, so that the valves to be processed in the storage track 5 are fed between the two feeding guide rails 1 of the guide rail assembly through the first outlet 6, the discharge channel 8, the second outlet 7, and the transition channel. The gap between the first outlet 6 and the second outlet 7 is greater than twice the valve stem diameter to reduce the simultaneous loading of valves on both sides of the same storage track 5. If the valve becomes blocked when entering the first discharge port 6, it can be gently shaken during the feeding process to facilitate smooth entry of the valve into the transition channel 14 via the first discharge port 6, the discharge channel 8, and the second discharge port 7. Since the outlet gap of the transition channel 14 near the second discharge port 7 is larger than the outlet gap near the feeding guide rail 1, the valve enters the guide rail assembly sequentially in the transition channel 14. This invention eliminates the need for manual placement of the valves between the two feeding guide rails 1 in the guide rail assembly, thus eliminating the need to adjust the valve's position before placing it between the two feeding guide rails 1, greatly improving valve production efficiency. Before feeding the guide rail assembly, the operator can place the valve to be processed in the storage rail 5 in the material holding cavity, and seal the transition channel 14 by fixing the baffle 20. The threaded post 22 on the upper end face of the first boss 21 passes through the second mounting hole 24 on the second boss 23 and is threadedly connected to the second nut 25. During the processing of the valve in the guide rail assembly, the next valve to be processed needs to be fed after the previous processing cycle is completed. During feeding, the valve enters the feed port 11. After each processing cycle, during the rotation of the feed cylinder 9, the feed port 11 rotates 180 degrees to the other side, and the valve in the feed chamber 10 is discharged from the feed port 11. Similarly, the valves in the guide rail assembly are processed one by one. The volume of the feed chamber is adjusted so that the feed chamber 10 can only accommodate one valve. When producing valves of different specifications, the position of the first limiting plate 32 in the feed chamber 10 can also be adjusted by setting the length of the first screw so that the feed chamber 10 can only accommodate one valve.

[0021] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
