Description

Technical Field

[0001] This invention belongs to the field of material pouring and pushing technology, and particularly relates to a material pouring and pushing device and an intelligent packaging line using the device. Background Technology

[0002] Bolts are indispensable fasteners in machinery manufacturing, construction engineering and various equipment assembly. At the end of the bolt production line, it is usually necessary to quantitatively remove a large number of bolts stored in a centralized manner from the raw material barrels and transport them to an automatic packaging machine for weighing, counting, bagging or boxing. A matching material pouring and pushing barrel device and a corresponding intelligent packaging line are needed to complete the above operations.

[0003] According to Chinese Patent Publication No. CN119796890B, a material frame tilting production line is disclosed, including a material cart conveyor line for conveying material frame carts. The material cart conveyor line is provided with a material frame lifting mechanism, a material frame tilting and unloading mechanism, and a material frame lowering mechanism in sequence in the middle of the material cart conveyor line.

The material frame conveying mechanism includes two side plate supports, which are located on both sides of the top of the second support body.

[0004] However, the above solution has the following drawbacks due to the lack of clamping and limiting of the hopper: the hopper is prone to shaking during the flipping process, and when the flipping angle is too large, the hopper is prone to falling off and tipping over, which poses certain safety hazards. Summary of the Invention

The invention proposes a material pouring and pushing device and an intelligent packaging line using the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A material-pouring and pushing device includes a tilting component and two side supports, wherein the tilting component is rotatably connected between the two side supports via a rotating shaft, and further includes: The clamping plate is movably mounted on one side of the inner wall of the flipping part; A lead screw seat is connected to one side of the clamping plate. The turning part has a slot, and the lead screw seat is slidably connected to the slot. The movable lead screw is connected to the end of the lead screw seat away from the clamping plate. The support plate is slidably connected to the underside of the tilting component and is used to drive the moving lead screw to rotate.

[0007] Preferred options also include: The transmission gear is connected to the end of the movable lead screw away from the lead screw seat; The movable rack meshes with the transmission gear on one side; A movable rod is connected to the bottom of a movable rack, and the other end of the movable rod is connected to the top of a support plate.

[0008] Preferred options also include: Mounting base, connected to one side of the flipping component, the moving rod is slidably connected to the mounting base; A support spring is sleeved on the outer surface of the moving rod, and the two ends of the support spring are respectively connected to the top surface of the mounting base and the bottom end of the moving rack.

[0009] Preferred options also include: A connecting frame is attached to one side of the flipping component, and the movable lead screw is rotatably connected to the connecting frame. A fixed groove is connected to one side of the flipping component, and the movable rack is slidably connected inside the fixed groove.

[0010] Preferred options also include: A guide trough seat is connected between two side supports, and the guide trough seat is located on one side of the flipping component; The vibrating block is arranged parallel to the bottom of the guide trough seat and is used to vibrate the guide trough seat. A sliding rod is connected to one side of the vibrating block; The movable plate is connected to the end of the sliding rod away from the vibrating block.

[0011] Preferred options also include: An mounting plate is disposed between the vibrating block and the movable plate, the mounting plate is connected between two side supports, and the sliding rod is slidably connected to the mounting plate; A return spring is sleeved on the outer surface of the sliding rod, and the two ends of the return spring are respectively connected to the mounting plate and the moving plate.

[0012] Preferred options also include: A rotating cam is rotatably connected between two side supports via a rotating shaft, and the rotating cam is in contact with the moving plate; The first synchronous pulley is located on one side of the side bracket and is connected to the rotating shaft. The second synchronous pulley is located on one side of the side bracket and is connected to the rotating shaft. A synchronous belt is used to drive the connection between the first synchronous pulley and the second synchronous pulley.

[0013] Preferred options also include: A hydraulic push rod is rotatably connected between two side supports via a connecting shaft, and the output end of the hydraulic push rod is rotatably connected to the tilting component.

[0014] Furthermore, the present invention also discloses an intelligent packaging line, including a material pouring and pushing device, and further comprising: A conveyor line is connected to one side of the side support, and the conveyor line is located below the turning component; A material holding mechanism is connected to the other side of the side support, and one end of the material guide trough extends into the material holding mechanism; The sensor is located at the end of the conveyor line away from the tipping component and is used to intelligently sense the position of the hopper.

[0015] Preferred options also include: The material return mechanism is set parallel to one side of the conveyor line and is used to recover empty hoppers; The material conveying mechanism is arranged parallel to one side of the return material mechanism and is used to convey the full hopper; The transfer mechanism is arranged parallel to the side of the conveyor line closest to the sensor; A guide rail is horizontally positioned at one end of the material conveying mechanism and the material return mechanism, and the transfer mechanism is drivenly connected to the guide rail.

[0016] Compared with existing technologies, the material pouring and pushing device and the intelligent packaging line using the above-mentioned technical solution have the following advantages: 1. In this invention, when the material-turning component flips, the hopper applies pressure to the support plate, sequentially driving the moving rod, moving rack, transmission gear, and moving screw. This causes the screw seat to move the clamping plate towards the center inside the material-turning component, thereby bringing the two clamping plates in the same group closer to the side wall of the hopper and achieving stable clamping. On the one hand, the clamping plates accurately position the hopper, enabling automatic hopper alignment. On the other hand, during the flipping process, an effective clamping limit is formed on the hopper, significantly improving the stability of the hopper during flipping and preventing the hopper from separating from the material-turning component and tipping over due to excessive flipping angle, ensuring safe and reliable material unloading operations. When the hydraulic push rod drives the material-turning component to reset, the support plate separates from the hopper, and the support spring automatically drives the moving rack to move in the opposite direction. Through the reverse transmission of the transmission gear and the moving screw, the screw seat drives the clamping plate away from the hopper, releasing the limit clamping and returning to its original position, facilitating the next clamping operation.

[0017] 2. In this invention, the tilting component and hopper are driven to flip and reset by a hydraulic push rod. The rotating cam is driven to rotate by a mechanical transmission consisting of a rotating shaft, a second synchronous wheel, a synchronous belt and a first synchronous wheel. With the help of a reset spring, the moving plate and multiple sliding rods can continuously reciprocate. Finally, the vibrating block is driven to regularly vibrate the bottom of the guide trough seat, so that the bolts are evenly dispersed during the unloading process. This effectively avoids the jamming phenomenon caused by the stacking of bolts and significantly improves the smoothness of unloading and the efficiency of operation.

[0018] 3. In this invention, the precise alignment of the transfer mechanism and the material conveying mechanism enables the automatic transfer of the hopper filled with bolts to the transfer mechanism, resulting in tight connection and accurate positioning. After the transfer mechanism and the return mechanism are aligned, the linear module, in conjunction with the push plate, pushes the hopper to the conveyor line. The sensor and operating system are used to achieve automatic positioning and orderly flow, avoiding jamming and tipping failure, and improving the intelligence level of the device.

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.

[0022] Please see Figures 1-6 The present invention provides a technical solution: A material-pouring and pushing device includes a tilting component 10 and two side supports 11. The tilting component 10 is rotatably connected between the two side supports 11 via a rotating shaft 13. The device also includes: Hydraulic push rod 12 is rotatably connected between two side supports 11 via a connecting shaft, and the output end of hydraulic push rod 12 is rotatably connected to the tilting component 10. Two sets of clamping plates 604, each set of clamping plates 604 consists of two symmetrically arranged clamping plates 604, which are movably set on one side of the inner wall of the flipping part 10. Two sets of lead screw seats 605, each set of lead screw seats 605 consists of two symmetrically arranged lead screw seats 605, connected to one side of the clamping plate 604. The flipping part 10 has a slot, and the lead screw seat 605 is slidably connected in the slot. Two sets of movable lead screws 610, each set of movable lead screws 610 consists of two symmetrically arranged movable lead screws 610, and are connected to the end of the lead screw seat 605 away from the clamping plate 604. Two support plates 602 are vertically slidably connected below the tilting component 10 and are used to drive the moving screw 610 to rotate; Two sets of transmission gears 601, each set of transmission gears 601 consists of two symmetrically arranged transmission gears 601, connected to the end of the movable lead screw 610 away from the lead screw seat 605; Two sets of movable racks 607, each set of movable racks 607 consists of two symmetrically arranged movable racks 607, and the movable racks 607 are meshed and connected to one side of the transmission gear 601; Two sets of movable rods 609, each set of movable rods 609 consists of two symmetrically arranged movable rods 609, the movable rods 609 are connected to the bottom of the movable rack 607, and the other end of the movable rods 609 are connected to the top of the support plate 602; Two sets of mounting bases 603, each set of mounting bases 603 consists of two symmetrically arranged mounting bases 603, connected to one side of the flipping component 10, and the moving rod 609 is slidably connected to the mounting base 603; Two sets of support springs 608, each set of support springs 608 consists of two symmetrically arranged support springs 608, which are sleeved on the outer surface of the moving rod 609. The two ends of the support springs 608 are respectively connected to the top surface of the mounting base 603 and the bottom end of the moving rack 607. Two sets of connecting frames 611, each set of connecting frames 611 consists of two symmetrically arranged connecting frames 611, connected to one side of the flipping component 10, and the moving screw 610 is rotatably connected to the connecting frame 611; Two sets of fixed slot seats 606, each set of fixed slot seats 606 consists of two symmetrically arranged fixed slot seats 606, connected to one side of the flipping component 10. The movable rack 607 is slidably connected in the fixed slot seat 606. A limit slider is provided in the fixed slot seat 606. A limit groove is provided on one side of the movable rack 607. The limit slider is slidably connected to the limit groove.

[0023] The specific usage method and working principle are as follows: the conveyor line 7 moves the hopper into the tipping component 10. At this time, the support plate 602 is located below the hopper, and the bottom of the hopper is not in contact with the support plate 602. Then, the hydraulic push rod 12 drives the tipping component 10 to flip. During the flipping process of the material-turning component 10, the two support plates 602 are attached to the bottom surface of the hopper. As the material-turning component 10 flips, the hopper applies pressure to the support plates 602. The support plates 602 drive the moving rod 609 to move downwards. The moving rod 609 drives the moving rack 607 to move. The moving rack 607 drives the transmission gear 601 to rotate. The transmission gear 601 drives the moving screw 610 to rotate. The moving screw 610 drives the screw seat 605 to move within the slot. The screw seat 605 drives the clamping plate. 604 moves towards the inner center of the flipper 10, causing the two clamping plates 604 in the same group to move closer to the side wall of the hopper and complete the clamping and stabilizing of the side wall of the hopper. On the one hand, the clamping plates 604 position the hopper to ensure the hopper is aligned. On the other hand, the clamping plates 604 limit the hopper to ensure stability during the flipping process and prevent the hopper from separating from the flipper 10 and tipping over when the flipper 10 flips at a large angle, thereby improving the safety of the operation. After the bolts in the hopper are emptied, the hydraulic push rod 12 drives the tilting component 10 to flip and reset. The tilting component 10 then drives the hopper to flip and reset. Once the tilting component 10 is reset, the hopper falls back onto the conveyor line 7. At this time, the support plate 602 separates from the hopper and is no longer under pressure. The support spring 608 then drives the moving rack 607 to move upward. The moving rack 607 drives the transmission gear 601 to rotate. The transmission gear 601 drives the moving screw 610 to rotate. The moving screw 610 drives the screw seat 605 to move away from the hopper and allows the clamping plate 604 to return to its original position, thereby releasing the hopper from the limiting clamp and facilitating the next clamping operation.

[0024] Please see Figures 1-2 and Figures 7-8 It also includes: The material guide trough seat 4 is connected between two side supports 11, and the material guide trough seat 4 is located on one side of the flipping component 10; Multiple vibrating blocks 508 are arranged in parallel below the material guide trough seat 4, and the multiple vibrating blocks 508 are distributed in a linear array to vibrate the material guide trough seat 4. Multiple sliding rods 509 are connected to one side of the vibrating block 508; The movable plate 505 is connected to the end of the sliding rod 509 away from the vibrating block 508; Mounting plate 507 is disposed between vibrating block 508 and moving plate 505. Mounting plate 507 is connected between two side brackets 11. Sliding rod 509 is slidably connected to mounting plate 507. Multiple return springs 506 are sleeved on the outer surface of the sliding rod 509, and the two ends of the return springs 506 are respectively connected to the mounting plate 507 and the moving plate 505. A rotating cam 504 is rotatably connected between two side supports 11 via a rotating shaft, and the rotating cam 504 is in contact with the moving plate 505; Two first synchronous pulleys 501 are disposed on one side of the side bracket 11, and the first synchronous pulleys 501 are connected to the rotating shaft; Two second synchronous pulleys 503 are disposed on one side of the side bracket 11. The second synchronous pulleys 503 are connected to the rotating shaft 13. The diameter of the second synchronous pulley 503 is larger than the diameter of the first synchronous pulley 501. Two synchronous belts 502 are connected between the first synchronous pulley 501 and the second synchronous pulley 503.

[0025] The specific usage method and working principle are as follows: During the process of the hydraulic push rod 12 driving the tilting component 10 and the hopper to flip and reset, the tilting component 10 will drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the second synchronous wheel 503 to rotate. The second synchronous wheel 503 drives the first synchronous wheel 501 to rotate through the synchronous belt 502. Since the diameter of the first synchronous wheel 501 is smaller than the diameter of the second synchronous wheel 503, the first synchronous wheel 501 can rotate several times by rotating the second synchronous wheel 503 about half a turn. The first synchronous wheel 501 drives the rotating cam 504 to rotate through the rotating shaft. The rotating cam 504, together with the reset spring 506, drives the moving plate 505 to reciprocate. The moving plate 505 drives multiple sliding rods 509 to reciprocate. The sliding rods 509 drive the vibrating block 508 to knock on the bottom of the guide trough seat 4, so that the guide trough seat 4 can vibrate. The vibration of the guide trough seat 4 disperses the bolts on the guide trough seat 4, preventing the bolts from stacking and jamming the material, and ensuring the smoothness of material pouring.

[0026] Please see Figures 1-2 A smart packaging line, including a material dispensing and pushing device, and further comprising: Conveyor line 7 is connected to one side of side bracket 11, and conveyor line 7 is located below the turning component 10; The material holding mechanism 3 is connected to the other side of the side support 11, and one end of the material guide trough seat 4 extends into the material holding mechanism 3; Sensor 14 is located at the end of the conveyor line 7 away from the tipping component 10 and is used to intelligently sense the position of the hopper; The material return mechanism 2 is arranged parallel to one side of the conveyor line 7 and is used to recover empty hoppers; The material conveying mechanism 1 is arranged parallel to one side of the material return mechanism 2 and is used to convey the full material hopper; The transfer mechanism 8 is arranged parallel to the side of the conveyor line 7 near the sensor 14; The linear module is mounted on the assembly plate below the conveyor line 7 and the transfer mechanism 8. A push plate is connected above the linear module to push the hopper. The guide rail 9 is horizontally arranged at one end of the material conveying mechanism 1 and the material return mechanism 2, and the transfer mechanism 8 is drivenly connected to the guide rail 9.

[0027] The specific usage method and working principle are as follows: Figure 1 As shown, the transfer mechanism 8 moves to the right on the guide rail 9, so that the transfer mechanism 8 moves to a position aligned with the conveying mechanism 1. Then, the hopper filled with bolts is conveyed by the conveying mechanism 1 to one end close to the transfer mechanism 8, and the hopper filled with bolts moves onto the transfer mechanism 8. Then, the transfer mechanism 8 drives the hopper to move to the left. When the transfer mechanism 8 moves to be flush with the return mechanism 2, the linear module drives the push plate to move, and the push plate drives the hopper to move towards the conveyor line 7. When the sensor 14 senses that the hopper has moved to the appropriate position, the sensor 14 controls the linear module to reset the push plate through the operating system. The conveyor line 7 drives the hopper to move towards the tilting component 10. Then, the tilting component 10 drives the hopper to flip and tilts the bolts in the hopper into the guide trough seat 4, and then delivers the bolts to the loading mechanism 3. After that, the tilting component 10 drives the hopper to flip and reset. The hopper is reset by the tipping component 10, causing it to fall back onto the conveyor line 7. The conveyor line 7 moves the empty hopper to the end of the conveyor line 7. When the sensor 14 senses that the empty hopper has moved to the appropriate position, the sensor 14 controls the conveyor line 7 to stop through the control system. Then, the linear module moves the empty hopper through the pusher plate, causing the empty hopper to move onto the transfer mechanism 8. Since the transfer mechanism 8 is flush with the return mechanism 2 at this time, the transfer mechanism 8 moves the empty hopper onto the return mechanism 2, and the return mechanism 2 moves the empty hopper into the warehouse. By precisely aligning the transfer mechanism 8 with the material conveying mechanism 1, the hopper filled with bolts is automatically transferred to the transfer mechanism 8, with tight connection and accurate positioning. After the transfer mechanism 8 is aligned with the return mechanism 2, the linear module, together with the push plate, pushes the hopper to the conveyor line 7, and uses the sensor 14 and the operating system to achieve automatic positioning and orderly flow, avoiding jamming and tipping failure, and improving the intelligence level of the device.
