Description

Technical Field

[0001] This invention relates to the field of shovel manufacturing technology, specifically to an automatic feeding device. Background Technology

[0002] A shovel is a widely used tool in daily life, typically used in agriculture, construction, and other fields. It can be used to dig, level, and move materials such as soil and gravel. The head of a shovel is usually made of iron, while the handle is usually made of wood or metal.

[0003] The manufacturing process of a shovel typically includes the following steps: heating the metal material and cutting it to a specified size; forging the metal material into the shape of the shovel head; using a stamping machine to shape the shovel head; then heat-treating the shovel head to increase its hardness and wear resistance; and finally assembling the handle part with the shovel head.

[0004] When processing metal materials, the heated metal is usually extruded into thin sheets, cut into the shape of a shovel by a cutting machine, softened by heating, and then stamped on a stamping machine to form the shape of the part connecting to the handle. Holes are punched in the stamped part to facilitate the connection and fixation of the handle to the shovel head with nails. After stamping, workers use iron hooks to hook the through holes on the shovel head and put it into a quenching device for quenching. However, the quenching process requires manual labor to align and hook the shovels one by one onto the hooks on the quenching device to move the shovels one by one. This step is labor-intensive and inefficient. In addition, due to the different sizes of the quenching devices, workers are at risk of being burned by the shovels when hooking them. Therefore, in order to improve the efficiency of shovel quenching and reduce the risks to workers, we propose an automatic feeding device. Summary of the Invention

[0009] The second docking block is provided with an inclined slide rail, and the first docking block is provided with a groove that docks with the slide rail. The slide rail slides in the groove, and the second docking block slides at an inclination on the first docking block. A roller is provided on the side of the docking plate near the second docking block, and the roller is in contact with the second docking block. The second docking block is provided with a docking groove.

[0010] The hook has hooks at both ends, with the two hooks facing opposite directions. The hook on the hook closest to the second docking block faces downwards, and the hook is provided with a support ring.

[0011] The hook-releasing mechanism includes: Drive cylinder two, which is mounted on the top of the housing; A sliding frame is slidably mounted on the outer casing, and the output end of the second drive cylinder is connected to the sliding frame. Drive cylinder three, which is mounted on the sliding frame; The hook release frame is slidably mounted on the sliding frame and has multiple hook release slots. The output end of the drive cylinder is connected to the hook release frame. The hook placement groove corresponds one-to-one with the shovel groove. Multiple hooks are detachably installed in the hook placement groove. An installation component is provided on the hook placement groove, and the installation component is used to connect the hooks to the docking block two.

[0012] The installation components include: A pushing groove is formed on the side of the hook release groove; A fourth drive cylinder is installed on the side of the push groove; A toggle lever is rotatably mounted on the output end of the fourth drive cylinder.

[0013] The driving mechanism includes: A drive frame that slides within the housing; A drive groove is provided in the outer casing, the drive frame is slidably connected to the drive groove, and a tensioning wheel is provided on one end of the drive groove near the second drive cylinder; Motor 2, the motor 2 is installed on the side of the drive slot; A transmission belt is fitted onto the tensioning pulley and the output end of the second motor, and the transmission belt is fixedly connected to the drive frame; Slide 1, which is disposed on the drive frame, and slide 1 corresponds to hook release groove 1; The second slide is disposed on one side of the first slide and is opposite to the first slide. The end of the second slide away from the drive frame is arc-shaped. Drive cylinder five is disposed between slide groove one and slide groove two.

[0014] The driving mechanism also includes: The drive ring has a sliding shaft 1 and a sliding shaft 2 respectively on its two sides. The sliding shaft 1 is slidably disposed in the sliding groove 1, and the sliding shaft 2 is slidably disposed in the sliding groove 2. The output end of the drive cylinder 5 is rotatably connected to the end of the drive ring near the sliding shaft 1.

[0015] The working principle and beneficial effects of this invention are as follows: 1. In this invention, by setting up docking block one and docking block two, the extension gas spring pushes docking block one and the retraction gas spring stretches docking block two, so that docking block one and docking block two are always separated before they come into contact with the shovel head. When docking block one comes into contact with the shovel head, the extension of drive cylinder one compresses the extension gas spring, and at the same time, the roller squeezes docking block two, so that docking block two slides on docking block one at an angle. The retraction gas spring is stretched and elongated. A hook is set in the docking groove on docking block two. The docking groove holds the hook. When pulled by the drive ring, the hook can separate from the docking groove. By setting docking block one and docking block two, the hook on the hook can be accurately inserted into the through hole on the shovel, ensuring that the shovel can be driven by the hook for quenching. 2. In this invention, by setting a support ring on the hook, the hooks at both ends of the hook are bent to both sides. By setting the support ring, the hooks support each other and maintain a horizontal state when they are in the hook placement groove. The hooks will not tilt due to the support of the hooks on the hooks, so that the hooks cannot be aligned with the second docking block. At the same time, the actuating rod can push the support ring to move the hook. 3. In this invention, by setting slide groove one and slide groove two, the driven ring slides between slide groove one and slide groove two. Vertical lifting and lowering movement can be performed by drive cylinder five. Since slide shaft one and slide shaft two are not aligned, when drive cylinder five pushes the driven ring to the arc-shaped part on slide groove two, the driven ring will rotate and connect with the hook. The driven frame will slide through motor two and transmission belt. The sliding groove one and slide groove two allow the lifting and rotation of the driven ring to be controlled by drive cylinder five alone. 4. In this invention, by setting a feeding shaft, after the iron shovel head is placed on the feeding plate, the hook drives the iron shovel head to move away. At this time, the motor drives the feeding reel to rotate, so that another feeding plate rotates to the top. The worker can place the iron shovel head in the iron shovel slot through the feeding port. The feeding plate that was originally at the top rotates to the bottom of the outer shell to contact the quenching liquid for cooling. By setting the feeding reel, the worker can continuously place iron shovel heads on the feeding plate. The iron shovel heads are quenched in batches and the feeding plate can be cooled to prevent damage. 5. In this invention, by setting a feeding mechanism, iron shovel heads can be processed in batches; by setting a docking mechanism, hooks can be driven to accurately dock with the through holes on the iron shovel heads; by setting a hook-releasing mechanism, hooks can be supplied to the docking mechanism; and by setting a driving mechanism, the iron shovel heads can be automatically driven to reciprocate in the quenching liquid for quenching.

Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all 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.

[0019] like Figures 1-12 As shown, this embodiment proposes an automatic feeding device, including a housing 1 and iron shovel heads 2. The housing 1 is provided with a feed inlet 3 and a discharge outlet 4. Quenching liquid is placed at the bottom of the housing 1. The device includes a feeding mechanism, a docking mechanism, a hooking mechanism, and a driving mechanism. The feeding mechanism is installed at the feed inlet 3 of the housing 1 and is provided with multiple iron shovel heads 2. The feeding mechanism is used to drive the multiple iron shovel heads 2 to move. The docking mechanism is installed inside the housing 1 and is located on the side of the feeding mechanism near the discharge outlet 4. The docking mechanism includes a hook 37, which is used to dock the hook 37 with the through hole on the iron shovel head 2. The docking mechanism includes a docking block 5 and a docking block 6. The docking block 5 is provided with... Above the feeding mechanism, the second docking block 6 is slidably mounted on the first docking block 5. The second docking block 6 is detachably connected to the hook 37. The hook-releasing mechanism is located inside the outer shell 1 and is located on the side of the docking mechanism near the discharge port 4. The hook-releasing mechanism is provided with multiple hooks 37. The hook-releasing mechanism is used to dock the hooks 37 on the second docking block 6. The driving mechanism is located on the side of the outer shell 1 near the discharge port 4. The driving mechanism is used to drive the iron shovel head 2 to move in the outer shell 1 through the hooks 37. The hooks 37 extend into the through holes on the iron shovel head 2. The driving mechanism drives the iron shovel head 2 to move in the outer shell 1. The iron shovel head 2 slides across the quenching liquid at the bottom of the outer shell 1 for quenching. Half of the quenching liquid is water or quenching oil.

[0020] The feeding mechanism includes a motor 7, a feeding shaft 8, a feeding plate 9, and iron shovel slots 10. The motor 7 is installed at the feed inlet 3. The feeding shaft 8 is rotatably mounted in the housing 1 and is connected to the motor 7. The feeding plate 9 is arranged around the feeding shaft 8 and has multiple iron shovel slots 10. When the iron shovel head 2 is placed in the iron shovel slot 10, the part of the iron shovel head 2 with the through hole extends out of the iron shovel slot 10 near the discharge outlet 4. In this embodiment, there are three feeding plates 9 on the feeding reel, and each of the three feeding plates 9 has five iron shovel slots 10. The motor 7 is connected to the feeding reel. Driven by a belt or chain, the workers place the stamped shovels into the shovel slots 10 one by one, with the end of the shovel head 2, which is stamped into a circle and connected to the handle, facing inward towards the inside of the outer shell 1. After five shovel heads 2 are placed in the shovel slots 10 on a feeding plate 9, the drive mechanism drives the shovel heads 2 to move in the quenching liquid in the outer shell 1 for quenching via the hook 37. At this time, the motor 7 drives the feeding roller to rotate, causing a new feeding plate 9 to rotate to the top. At the same time, the feeding plate 9 that was originally on top will rotate to the bottom to contact the quenching liquid and cool the feeding plate 9.

[0021] The docking mechanism includes a drive cylinder 11, a docking plate 12, an extension gas spring 13, and a retraction gas spring 14. Multiple drive cylinders 11 are installed inside the outer casing 1, each corresponding to a shovel slot 10. The docking plate 12 is mounted on the output end of the drive cylinder 11. The extension gas spring 13 is mounted on the side of the docking plate 12 away from the drive cylinder 11, and its output end is connected to docking block 5. Both ends of the retraction gas spring 14 are rotatably connected to the docking plate 12 and docking block 6, respectively. The docking block 6 is provided with an inclined slide rail, and the docking block 5 is provided with a groove for engaging with the slide rail. The slide rail slides within the groove, and the docking block 6 slides at an angle on the docking block 5. The docking plate 12 has a... A roller 15 is provided, which fits against the second docking block 6. The second docking block 6 has a docking groove 16. The retraction gas spring 14 is kept in a retracted state. When the extension gas spring 13 pushes the first docking block 5, the second docking block 6 is pulled and does not move with the first docking block 5. When the drive cylinder 11 extends, the docking plate 12 pushes the first docking block 5 to contact the shovel head 2 first. At this time, the drive cylinder 11 continues to push the docking plate 12. At this time, the extension gas spring 13 is compressed, and the roller 15 compresses the second docking block 6. The second docking block 6 slides on the first docking block 5. The hook 37 slides with the second docking block 6 and extends into the through hole on the shovel head 2. When the second docking block 6 slides on the first docking block 5, the hook on the hook 37 slides toward the through hole on the shovel head 2.

[0022] Hooks are provided at both ends of hook 37, with the two hooks facing opposite directions. The hook on hook 37 closer to the docking block 26 faces downward. A support ring 17 is provided on hook 37. The height of the support ring 17 on hook 37 is equal to the height of the hook on hook 37 away from docking block 26. The cross-section of the side of hook 37 away from docking block 26 is rectangular. The rectangular shape facilitates the sliding of hook 37 in hook placement groove 22. When hook 37 is placed in hook placement groove 22, the support rings 17 on multiple hooks 37 contact each other with the hooks, so that hook 37 remains horizontal in hook placement groove 22.

[0023] The hook-releasing mechanism includes a second drive cylinder 18, a sliding frame 19, a third drive cylinder 20, and a hook-releasing frame 21. The second drive cylinder 18 is mounted on the top of the outer casing 1. The sliding frame 19 is slidably mounted on the outer casing 1. The output end of the second drive cylinder 18 is connected to the sliding frame 19. The third drive cylinder 20 is mounted on the sliding frame 19. The hook-releasing frame 21 is slidably mounted on the sliding frame 19 and has multiple hook-releasing slots 22. The output end of the third drive cylinder 20 is connected to the hook-releasing frame 21. The hook-releasing slots 22 are connected to the shovel slots 10. In a corresponding manner, multiple hooks 37 are detachably installed in the hook placement groove 22. An installation component is provided on the hook placement groove 22. The installation component is used to connect the hooks 37 to the docking block 2 6. The extension of the drive cylinder 2 18 can move the hook placement frame 21 to a position aligned with the docking block 2 6 through the sliding frame 19. After the hooks 37 are connected to the docking block 2 6 through the installation component, the drive cylinder 3 20 pushes the hook placement frame 21 to slide away from the docking block 2 6 on the sliding frame 19, so that the hooks 37 are separated from the hook placement groove 22.

[0024] The mounting assembly includes a push groove 23, a drive cylinder 24, and a lever 25. The push groove 23 is located on the side of the hook release groove 22. The drive cylinder 24 is mounted on the side of the push groove 23. The lever 25 is rotatably mounted on the output end of the drive cylinder 24. The lever 25 extends into the push groove 23. A spring is provided between the lever 25 and the output end of the drive cylinder 24. When the drive cylinder 24 extends, it can push the support ring 17 through the lever 25, causing the hook 37 to move out of the hook release groove 22. The lever 25 can only rotate in the direction of the docking block 6. After the hook 37 separates from the hook release groove 22, the hook 37 on the upper side of the hook release groove 22 slides down, and the drive cylinder 24 shortens. When the lever 25 contacts the support ring 17, the lever 25 rotates on the output end of the drive cylinder 24 and compresses the spring. The lever 25 moves to the side of the support ring 17 closer to the drive cylinder 24.

[0025] The driving mechanism includes a drive frame 26, a drive groove 27, a second motor 29, a transmission belt 30, a first slide groove 31, a second slide groove 32, and a fifth drive cylinder 33. The drive frame 26 slides within the outer casing 1. The drive groove 27 is located within the outer casing 1, and the drive frame 26 is slidably connected to the drive groove 27. A tensioning wheel 28 is located on one end of the drive groove 27 near the second drive cylinder 18. The second motor 29 is mounted on the side of the drive groove 27. The transmission belt 30 is sleeved on the output ends of the tensioning wheel 28 and the second motor 29, and the transmission... The belt 30 is fixedly connected to the drive frame 26. The first slide groove 31 is set on the drive frame 26, and the first slide groove 31 corresponds one-to-one with the hook release groove 22. The second slide groove 32 is set to the side of the first slide groove 31, and the second slide groove 32 is set opposite to the first slide groove 31. The end of the second slide groove 32 away from the drive frame 26 is set to be arc-shaped. The fifth drive cylinder 33 is set between the first slide groove 31 and the second slide groove 32. The transmission belt 30 rotates under the drive of the second motor 29, which can drive the drive frame 26 to reciprocate on the drive groove 27.

[0026] The driving mechanism also includes a driving ring 34, on which two sliding shafts 35 and 36 are respectively provided. Sliding shaft 35 slides in sliding groove 31, and sliding shaft 36 slides in sliding groove 32. The output end of the driving cylinder 33 is rotatably connected to the end of the driving ring 34 near sliding shaft 35. Sliding shaft 35 is located on one end of the driving ring 34, and sliding shaft 36 is located to the side of sliding shaft 35. The output end of the driving cylinder 33 is rotatably connected to one end of the driving ring 34. The positions of shaft 35 and sliding shaft 36 are not aligned. When the drive cylinder 33 pushes the driving ring 34 to slide in sliding groove 31 and sliding groove 32, the driving ring 34 will remain vertical. When the sliding shaft 36 moves to the arc-shaped part in sliding groove 32, sliding groove 32 will drive the driving ring 34 to rotate. The driving ring 34 will rotate to the top of the hook of hook 37. At this time, the drive cylinder 33 shortens, the motor 29 drives the drive frame 26 to move, and the driving ring 34 drives the shovel head 2 to move through the hook 37.

[0027] In summary, the working principle of this automatic feeding device is as follows: Multiple shovel heads 2 are placed on the shovel slots 10 on the feeding plate 9. Drive cylinder 2 18 extends, pushing the sliding frame 19 downwards. When the hook 37 aligns with the docking block 2 6, drive cylinder 4 24 extends, and the actuating plate pushes the support ring 17 on the hook 37 to move, causing the hook 37 to extend into the docking slot 16. Drive cylinder 4 24 then shortens, and drive cylinder 3 20 extends, pushing the hook-releasing frame 21 away from the docking block 2 6, causing the hook 37 docked with the docking block 2 6 to separate from the hook-releasing slot 22. Drive cylinder 1 11 extends, and docking block 1 5 contacts the shovel head 2. The docking plate 12 pushes the extension gas spring 13 to be compressed, and the roller 15 on the docking plate 12 presses against docking block 2 6, causing docking block 2 6 to slide on docking block 1 5. Docking block 2 6 drives the hook 37 to extend into the through hole on the shovel head 2. Motor 2 29 drives the transmission belt 30 to rotate, and the transmission belt 30 carries... The drive frame 26 slides in the drive groove 27. The drive cylinder 33 extends and pushes the drive ring 34 to slide in the slide groove 31 and slide groove 32. When the slide shaft 36 slides to the turn in the slide groove 32, the drive ring 34 rotates. The drive ring 34 rotates to a horizontal state. The transmission belt 30 drives the drive frame 26 and the drive ring 34 to move towards the hook 37. When the drive ring 34 moves above the hook 37, the drive cylinder 33 shortens, causing the drive ring 34 to rotate and hang on the hook on the hook 37. The motor 29 reverses. At this time, the drive ring 34 drives the shovel head 2 to separate from the shovel groove 10. The shovel groove 10 is quenched in the quenching liquid. The motor 7 drives the discharge shaft 8 to rotate, causing another discharge plate 9 to rotate to the top. The workers can place the stamped shovel head 2 into the shovel groove 10 on the upper discharge plate 9 for the next quenching.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
