Description

Technical Field

[0001] This invention relates to the field of aluminum rod production technology, specifically to a feeding and unloading device for aluminum rod production. Background Technology

[0002] With the development of the intelligent manufacturing equipment industry, aluminum rod production is gradually breaking away from the traditional model; relying on various intelligent casting equipment to achieve process control, the stability of aluminum rod products is ensured, while also helping the aluminum processing industry to achieve quality improvement, efficiency enhancement and green production. Currently, aluminum rod production mostly adopts deep-well casting. After casting, batches of aluminum rods are hoisted out of the deep well and then transported to the cutting equipment for end trimming and segment cutting. At present, the loading and unloading of aluminum rods mostly requires manual assistance to transport batches of aluminum rods to the cutting equipment for loading. This is labor-intensive and affects the continuity of operation, as it requires waiting for the cutting or hoisting process during loading and unloading.

[0010] Preferably, a positioning frame is fixedly installed at the end of the inner arc frame, and the positioning frame is fixedly installed inside the machine body. Multiple positioning rods are fixed between the outer arc frame and the inner arc frame and the machine body on both sides.

[0014] This invention provides a loading and unloading device for aluminum rod production. Compared with the prior art, it has the following advantages: (1) The aluminum rod production loading and unloading device, through the cooperation of the outer arc frame, the inner arc frame and the unloading plate, can guide, transport and store the aluminum rod body through the arc-shaped guide space. No manual operation is required and there is no need to wait for the cutting process during hoisting, ensuring the continuity of operation. Through the cooperation of the moving plate and the transmission components, the falling aluminum rod body can be buffered on the one hand, and batch aluminum rod bodies can be transferred and loaded on the other hand.

[0015] (2) The aluminum rod production loading and unloading device, through the cooperation of the unloading platform and the arc-shaped unloading frame, can complete the bearing through the unloading platform during the unloading process. As the end of the aluminum rod body contacts the inclined arc-shaped unloading frame and drives it to rotate during the placement process, it can effectively reduce the wear on the surface of the aluminum rod body and avoid the phenomenon of slippage of the aluminum rod body during the placement process, thus ensuring the stability and safety of the aluminum rod body during the hoisting and placement process.

[0018] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-11 The present invention provides two technical solutions, specifically including the following embodiments: Example

[0020] In this embodiment of the invention, an aluminum rod production loading and unloading device includes a machine body 1, with a support platform 2 fixed on both sides inside the machine body 1, and a loading platform 3 on the top of each support platform 2. The loading platform 3 is used to unload the hoisted aluminum rod body 4. Multiple telescopic sleeves 301 and a drive cylinder 302 are provided between the unloading platform 3 and the bearing platform 2 to drive the unloading platform 3 to move up and down horizontally. For details, please refer to Figures 1-4 The telescopic sleeve 301 is fixed between the unloading platform 3 and the bearing platform 2 to achieve limit support. The drive cylinder 302 is controlled based on the existing hydraulic controller and is used to drive the unloading platform 3 to move up and down. During operation, when the crane moves to transfer multiple aluminum rod bodies 4 to the unloading platform 3, the end of the aluminum rod body 4 first contacts the top of the unloading platform 3 on one side, and then the crane moves to the other unloading platform 3 while releasing the cable, so that the aluminum rod body 4 slowly falls on the two unloading platforms 3 to complete the bearing. Then the lifting device at the end of the aluminum rod body 4 can be removed. The aforementioned overhead crane hoisting, cables, and lifting tools are all equipment used in existing hoisting methods for aluminum rod body 4, and will not be described in detail here; An outer arc frame 5 and an inner arc frame 6 are fixedly installed between the two unloading platforms 3. An arc-shaped guide space is formed between the outer arc frame 5 and the inner arc frame 6, which is used to guide and transport the aluminum rod body 4 after unloading. When the aluminum rod body 4 is unloaded and carried by the two unloading platforms 3, the unloading platform 3 can be moved downward by the drive cylinder 302, so that the aluminum rod body 4 can contact the inner arc frame 6 and roll along the inner arc frame 6 into the arc-shaped guide space for storage. refer to Figures 1-4 The top surface of the inner arc frame 6 and the interior of the outer arc frame 5 are both set as inclined surfaces, so that when the aluminum rod body 4 is separated from the unloading table 3 and supported by the inner arc frame 6, it can roll along the inclined surface into the arc-shaped guide space. During the conveying process of the aluminum rod body 4, the shortest distance for the length of the aluminum rod body 4 to be used by the equipment must exceed the distance between the two unloading tables 3, and the longest distance is the distance between the unloading table 3 on one side and the inner wall of the machine body 1. refer to Figure 4 The maximum height of the unloading platform 3 exceeds the maximum height of the inner arc frame 6. The installation position of the unloading platform 3 is flush with the bottom of the inner arc frame 6 to avoid motion interference when conveying aluminum rod bodies 4 of different lengths. In this embodiment of the invention, a feeding plate 10 is fixedly installed on the side of the machine body 1 away from the outer arc frame 5. A drive rod 9 is rotatably assembled between the feeding plate 10 and the outer arc frame 5, and multiple flipping frames 901 are fixed on the outside of the drive rod 9. Multiple partition plates 1002 are fixed inside the feeding plate 10, so that multiple feeding channels are formed inside the feeding plate 10. Both ends of the feeding plate 10 are provided with moving plates 11. Multiple bearing plates 12 are slidably assembled on the side of the moving plates 11. A transmission component is provided between the bearing plates 12 and the moving plates 11 for guiding and limiting the aluminum rod bodies 4 conveyed to the inside of the feeding plate 10 in sequence, so that multiple aluminum rod bodies 4 can fall sequentially through the multiple feeding channels inside the feeding plate 10. Specifically, the drive rod 9 is driven by a separate motor to rotate multiple tilting frames 901 for tilting and conveying the aluminum rod body 4. Each 90° rotation of the tilting frame 901 constitutes one conveying cycle. The end length of the tilting frame 901 is less than the diameter of the aluminum rod body 4 but greater than its radius, ensuring that one aluminum rod body 4 can be conveyed to the unloading plate 10 during the rotation of the tilting frame 901. (Refer to...) Figure 3The flipping frame 901 has four ends, forming four flipping spaces between the four ends. By flipping, the aluminum rod body 4 inside the flipping space is transported to the unloading plate 10. When one end of the flipping frame 901 is flush with the end of the outer arc frame 5, the other end corresponding to the flipping frame 901 is flush with the top of the unloading plate 10, thereby ensuring the conveying effect of the aluminum rod body 4. When multiple aluminum rod bodies 4 enter the arc-shaped guide space, the aluminum rod body 4 at the very end can be blocked by the flipping frame 901. By rotating the flipping frame 901, the aluminum rod bodies 4 can be flipped and transported to the inside of the unloading plate 10 in sequence to achieve feeding assistance, so that the aluminum rod bodies 4 can fall into the inside of the loading frame 18 through the corresponding unloading channel. The flipping frame 901 is cross-shaped, with its inner side flush with the interior of the outer arc frame 5. This allows the aluminum rod body 4 to enter the interior of the flipping frame 901 when it rolls outward through the arc-shaped guide space. The feeding plate 10, the moving plate 11, and the bearing plate 12 are all installed at an angle of 3°-6° with the horizontal plane. This ensures that when the flipping frame 901 flips and transports the aluminum rod body 4 above the feeding plate 10, the aluminum rod body 4 can roll along the bearing plate 12 inside the two moving plates 11 until it falls into the corresponding feeding channel. The bearing plate 12 is used to bear and limit the two ends of the aluminum rod body 4, blocking different feeding channels to ensure that the aluminum rod body 4 can fall through the corresponding feeding channel. The feeding channel closest to the flipping frame 901 is not equipped with a bearing plate 12. This is the first feeding channel. The second feeding channel and the third feeding channel are in sequence after the first feeding channel. In specific operation, as the tilting frame 901 rotates, multiple aluminum rod bodies 4 can be sequentially transferred to the top of the unloading plate 10. At this time, by adjusting the distance between the two moving plates 11 to match the length of the aluminum rod body 4, the aluminum rod body 4 can roll above the unloading plate 10 guided by the moving plates 11. Since there are no bearing plates 12 at both ends of the first unloading channel, the aluminum rod body 4 can fall directly through the first unloading channel. When the aluminum rod body 4 falls through the first unloading channel, it can drive the bearing plate 12 above the second unloading channel to move horizontally through the transmission component, so that the two bearing plates 12 can slide to the top of both ends of the first unloading channel to complete the limit. When the second aluminum rod body 4 rolls into the top of the unloading plate 10, it can roll along the bearing plate 12 above the first unloading channel to the top of the second unloading channel until it falls through the second unloading channel. During the falling process, the bearing plate 12 above the third unloading channel is driven by the transmission component to slide to the top of the second channel, and so on. There are gaps between the multiple bearing plates 12, which will not affect the rolling of the aluminum rod body 4; Below the unloading plate 10 is a loading rack 18, which is used to push the falling aluminum rod body 4 into the cutting equipment to achieve segmented cutting operation; the aluminum rod body 4 falling through the unloading channel can fall into the loading rack 18, and the loading rack 18 completes the loading and pushing operation of the aluminum rod body 4. The transmission assembly includes a sliding plate 1202, which is slidably installed inside a moving plate 11 and fixedly connected to a support plate 12. A plurality of positioning blocks 13 cooperating with the sliding plate 12 are fixedly installed on the side of the moving plate 11 away from the support plate 12. A sliding shaft 14 is slidably installed inside the positioning block 13. A spring body 1401 is sleeved on the top of the sliding shaft 14. A buffer plate 1402 is rotatably connected to the bottom of the sliding shaft 14. A buffer spring 1403 is connected between the buffer plate 1402 and the sliding shaft 14. A traction frame 16 is fixedly installed on the side of the sliding plate 1202. A traction rope 15 is connected between the traction frame 16 and the corresponding end of the sliding shaft 14. A rotating wheel 1501 is rotatably installed inside the positioning block 13. The traction rope 15 passes around the corresponding rotating wheel 1501. A plurality of return springs 1203 are connected between the bottom of the support plate 12 and the interior of the moving plate 11. The positioning block 13, the sliding shaft 14, and the buffer plate 1402 are respectively located at the two ends of the corresponding feeding channel. The top surface of the buffer plate 1402 is arc-shaped, which is used to contact the arc-shaped surface of the buffer plate 1402 when the aluminum rod body 4 falls through the feeding channel, and drive the buffer plate 1402 and the sliding shaft 14 to slide downward. The sliding shaft 14 is always perpendicular to the horizontal plane during installation and operation. refer to Figures 6-10 The initial position between the buffer plate 1402 and the sliding shaft 14 is at a right angle. The assembly positions of the buffer plate 1402 and the sliding shaft 14 are located at the two ends of the corresponding feeding channel, and the end length of the buffer plate 1402 extends beyond the side of the moving plate 11. During operation, when the aluminum rod body 4 falls through the first feeding channel, its two ends can contact the buffer plate 1402 and drive the buffer plate 1402 and the sliding shaft 14 to move downward. At this time, the sliding shaft 14 can slide inside the corresponding positioning block 13. At this time, the spring body 1401 is compressed until the sliding shaft 14 moves to the limit position. Then the buffer plate 1402 is subjected to force and rotates along the sliding shaft 14, which compresses the buffer spring 1. 403 stretches until the buffer plate 1402 is separated from the end of the aluminum rod body 4. The buffer plate 1402 is reset by the buffer spring 1403. The sliding shaft 14 drives the buffer plate 1402 to move back to the initial position through the cooperation of the spring body 1401, completing the transmission process. During this process, as the sliding shaft 14 moves down, the sliding plate 1202 and the bearing plate 12 can slide inside the moving plate 11 through the cooperation of the traction rope 15 and the traction frame 16, so that the bearing plate 12 can slide to the top of the first feeding channel to complete the limit guidance. Through the cooperation of the buffer plate 1402, the gravity of the aluminum rod body 4 falling can be buffered. An electromagnet 17 is fixedly installed inside the positioning block 13, and an adsorption plate 1601 is fixedly installed on the top of the traction frame 16. Electromagnet 17 is an existing device used to achieve adsorption and positioning of adsorption plate 1601 by passing current. Adsorption plate 1601 is made of iron plate and is used to limit the sliding plate 1202 when in contact with electromagnet 17. During the above operation, as the sliding plate 1202 and the support plate 12 slide to the top of the first feeding channel, the return spring 1203 is stretched. At this time, the sliding plate 1202 can simultaneously drive the corresponding traction frame 16 to slide, so that the adsorption plate 1601 slides to the bottom of electromagnet 17 to complete the positioning. Until the subsequent feeding operation is completed, the electromagnet 17 is de-energized, canceling the adsorption and positioning of adsorption plate 1601, so that the sliding plate 1202 can drive the support plate 12 to return to the initial position through the cooperation of return spring 1203. The two ends of the return spring 1203 are rotatably connected to the sliding plate 1202 and the moving plate 11 respectively, so that when the sliding plate 1202 slides and stretches the return spring 1203, the return spring 1203 can be in an inclined state. The connection between the return spring 1203 and the sliding plate 1202 is located at the end of the sliding plate 1202 near the first feeding channel, so as to avoid motion interference when the sliding plate 1202 slides later. The multiple electromagnets 17 are energized sequentially. That is, the electromagnet 17 located at the end of the first feeding channel is kept energized. When the sliding plate 1202 at the end of the second feeding channel moves the traction frame 16 and the adsorption plate 1601 to below the energized electromagnet 17, the electromagnet 17 at the end of the second feeding channel is energized after the adsorption plate 1601 and the energized electromagnet 17 are fixed together. This process is repeated until all electromagnets 17 are de-energized after one feeding cycle is completed. After the electromagnets 17 are de-energized, the limiting force of the sliding plate 1202 is released, which allows the multiple sliding plates 1202 and the bearing plate 12 to be reset by the corresponding reset springs 1203. The rotating wheel 1501 is used to allow the traction rope 15 to pass around its outside, reducing the friction of the traction rope 15. The diameter of the end of the rotating wheel 1501 away from the positioning block 13 exceeds the diameter of the end that contacts the positioning block 13, giving the rotating wheel 1501 a certain function of binding the rope. When the sliding shaft 14 moves down and drives the sliding plate 1202 to slide, the sliding plate 1202 is positioned when the electromagnet 17 is energized. After the sliding shaft 14 is reset, the traction rope 15 is in a slack state. At this time, the limiting effect of the rotating wheel 1501 can prevent the traction rope 15 from detaching from the rotating wheel 1501. Multiple rollers 1201 are rotatably mounted on the bottom of the support plate 12. The rollers 1201 are used to contact the top of the partition plate 1002 to support the support plate 12 and the aluminum rod body 4. The bearing plates 12 at both ends of the second feeding channel are provided with slots for bearing operations. The slots are not shown in the figure. Specifically, when the bearing plate 12 slides above the first feeding channel, it can be inserted into the sliding groove 1001 inside the feeding plate 10. That is, the bearing plate 12 is supported by the inner wall of the feeding plate 10. When the subsequent bearing plates 12 are located above multiple feeding channels, they are supported by the corresponding two partition plates 1002. Therefore, when the two ends of the aluminum rod body 4 roll past the bearing plate 12, a more stable bearing effect can be ensured. The number of feeding channels formed inside the feeding plate 10 is three. When the number of aluminum rod bodies 4 to be fed at one time needs to be increased for batch operations, it is only necessary to increase the number of feeding channels and transmission components accordingly. Therefore, there is no limit to the number of aluminum rod bodies 4 to be fed at one time. The inner sides of the feeding plate 10 are provided with sliding grooves 1001. The movable plate 11 on one side is slidably assembled in the sliding groove 1001, and the movable plate 11 on the other side is fixedly connected to the feeding plate 10. Threaded rods 1003 are rotatably assembled in both sliding grooves 1001. The threaded rods 1003 pass through the end of the movable plate 11 on one side and are engaged with it. A transmission chain 1004 is rotatably connected between the ends of the two threaded rods 1003. The threaded rod 1003 is driven by a separate motor. Based on the cooperation of the sprocket and the transmission chain 1004, the threaded rod 1003 can rotate inside the feed plate 10. The threaded rod 1003 meshes with the moving plate 11 on one side. The movement of the threaded rod 1003 can drive the moving plate 11 on one side to slide inside the feed plate 10, thereby adjusting the distance between the two moving plates 11 to adapt to the guiding operation of aluminum rod bodies 4 of different lengths. One side of the unloading platform 3 is the unloading section, and the other side of the unloading platform 3 is the bearing section. That is, the end of the aluminum rod body 4 hoisted by the hoisting first contacts the unloading section, and then as the aluminum rod body 4 is slowly straightened, the other end contacts the bearing section to complete the unloading process. Therefore, when unloading aluminum rod bodies 4 of different lengths, the ends of the aluminum rod bodies 4 located in the unloading section are kept flush. Similarly, the threaded rod 1003 is engaged with the moving plate 11 near the bearing section to drive the moving plate 11 near the bearing section to move horizontally to achieve the adjustment operation. The moving plate 11 near the unloading section is fixedly connected to the unloading plate 10, and the threaded rod 1003 passes through the moving plate 11 near the unloading section and is always rotatably connected to it. An arc-shaped guide frame 1101 is fixedly installed at the end of the movable plate 11, and a guide rod 1102 is fixedly installed inside the movable plate 11. Multiple sliding plates 1202 are slidably sleeved on the outside of the guide rod 1102. The installation height of the arc-shaped guide frame 1101 exceeds that of the unloading plate 10, and is used to guide the aluminum rod body 4 so that the aluminum rod body 4 can enter between the two movable plates 11.

[0021] A positioning frame 7 is fixedly installed at the end of the inner arc frame 6. The positioning frame 7 is fixedly installed inside the machine body 1. Multiple positioning rods 8 are fixed between the outer arc frame 5 and the inner arc frame 6 and the machine body 1. The ends of the two unloading platforms 3 are slidably connected to the positioning frame 7. Both ends of the positioning frame 7 are fixedly connected to the inner wall of the machine body 1 to ensure the load-bearing effect of the inner arc frame 6. Positioning rods 8 are fixed between the outer arc frame 5 and the machine body 1 on both sides and at the bottom to ensure the load-bearing effect on the aluminum rod body 4. Multiple limit frames 19 are fixedly installed on the top of the feeding rack 18. Multiple rubber rollers 1901 are rotatably mounted on the inner side of the limit frame 19. A drive belt 1902 is rotatably connected to the bottom inner side of the limit frame 19. The drive belt 1902 is driven by a separate motor. When the aluminum rod body 4 falls into the corresponding limit frame 19, it is pushed into the cutting equipment by the drive belt 1902 and the rubber rollers 1901 for auxiliary support, thus realizing the feeding operation.

[0022] With the cooperation of the outer arc frame 5, the inner arc frame 6, and the unloading plate 10, the aluminum rod body 4 can be guided, transported, and stored by the arc-shaped guide space. No manual operation is required, and there is no need to wait for the cutting process during hoisting, ensuring the continuity of operation. With the cooperation of the moving plate 11 and the transmission components, batches of aluminum rod bodies 4 can be transferred and loaded. Compared with the traditional lifting and handling mode, it is more convenient and can facilitate batch operation for different quantities of aluminum rod bodies 4, thus improving the applicability of the equipment. Example 2: Based on Example 1, the top of the unloading platform 3 is provided with multiple concave grooves 305, and each concave groove 305 is rotatably connected to an arc-shaped unloading frame 303. A rubber pad 3031 is fixedly installed inside the arc-shaped unloading frame 303. A limiting shaft 304 is fixedly installed inside the unloading platform 3. Multiple bushings 3041 are rotatably sleeved on the outside of the limiting shaft 304. The bushings 3041 are fixedly connected to the corresponding arc-shaped unloading frame 303. Torsion springs 3042 are provided between both ends of the bushings 3041 and the limiting shaft 304.

[0023] refer to Figures 1-4Multiple arc-shaped unloading racks 303 on one side are tilted at an angle of 60° by the limiting force of torsion springs 3042. When multiple aluminum rod bodies 4 are hoisted and transferred to the unloading platform 3, the ends of the aluminum rod bodies 4 first come into contact with the tilted arc-shaped unloading racks 303. Then, as the aluminum rod bodies 4 are slowly placed above the two unloading platforms 3, the arc-shaped unloading racks 303 are able to be driven by force to rotate the bushings 3041 along the limiting shaft 304. At this time, the torsion springs 3042 store force until the aluminum rod bodies are fully rotated. After the aluminum rod body 4 separates from the arc-shaped unloading rack 303, the arc-shaped unloading rack 303 is reset to the inclined state by the cooperation of the torsion spring 3042. With the setting of the arc-shaped unloading rack 303, as the end of the aluminum rod body 4 contacts the inclined arc-shaped unloading rack 303 and drives it to rotate during the placement process, the wear on the surface of the aluminum rod body 4 can be effectively reduced, and the slippage of the aluminum rod body 4 during the placement process can be avoided, ensuring the stability and safety of the aluminum rod body 4 during the hoisting and placement process.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
