Description

Technical Field

[0001] The invention relates to the technical field of metal plate rolling and feeding, in particular to a feeding device for cabinet metal plate rolling. Background Art

[0002] During the rolling process of cabinet metal plates, an efficient feeding device is key to ensuring production efficiency and product quality. Traditional feeding devices have many problems: on the one hand, the lack of coordination between the feeding transmission mechanism and the clamping mechanism makes it difficult to stably transmit metal plates of different thicknesses, and is prone to deviation and jamming, affecting continuity; on the other hand, the single-layer unloading component is poorly designed, and the unloading quantity cannot be accurately controlled, which can easily lead to multiple layers of metal plates entering the guide rail at the same time, causing blockage and damage to the equipment; on the other hand, the speed limiter has limited adjustment capabilities and cannot flexibly adjust the sliding speed according to the movement state of the metal plate, causing metal plates to pile up or collide, reducing production efficiency.

[0003] In the field of cabinet metal plate rolling, traditional feeding devices mostly use horizontal feeding methods. This method requires a large power to overcome the friction between the metal plate and the conveying surface, resulting in high energy consumption. With the increasing prominence of energy issues, reducing energy consumption in the production process has become an important direction for the development of the industry. Inclined feeding, as a potential energy-saving solution, uses gravity to assist the transportation of metal plates, which can effectively reduce feeding power consumption. However, the inclined feeding method also brings some new challenges. For example, the stability of the metal plate on the inclined surface is difficult to control, and it is easy to slip, deflect or even get stuck, affecting the accuracy and continuity of feeding. In addition, how to ensure the single-layer separation, precise unloading and stable transmission of metal plates while tilting the feeding is a key technical problem to achieve efficient and energy-saving feeding.

[0030] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 - Figure 10The feeding device for rolling metal plates in a cabinet shown in the figure includes a mounting frame 1, a guide rail 2, an inclined loading frame 3, a loading and conveying mechanism 4 and a pressing mechanism 5. The guide rail 2 is inclined and arranged on the mounting frame 1 with an adjustable angle. The end of the guide rail 2 is connected to a horizontal conveying platform. The roller for rolling the metal plate 6 is arranged on the horizontal conveying platform. The inclined loading frame 3 is arranged on the mounting frame 1 and its inclination angle is perpendicular to the inclination angle of the guide rail 2. A fixed plate 7 with the same inclination angle as the guide rail 2 is installed on the mounting frame 1. A lifting plate 8 that can be slidably arranged along its height direction is provided in the inclined loading frame 3. The metal plates 6 are stacked on the lifting plate 8 in sequence. The loading and conveying mechanism 4 is installed on the side of the fixed plate 7 close to the guide rail 2, and the pressing mechanism 5 is installed on the other side of the fixed plate 7. The material transmission mechanism 4 includes a driving wheel 9 that elastically contacts the top metal plate 6, the clamping mechanism 5 includes a clamping rod 10 that elastically contacts the top metal plate 6, and a single-layer unloading component 11 is provided on the guide rail 2. The single-layer unloading component 11 includes a material baffle plate 12 that is perpendicular to the inclination angle of the guide rail 2, an inclined plate 13 that is inclined to the guide rail 2, a reverse rotating wheel 14 that is arranged between the driving wheel 9 and the inclined plate 13, and a speed limiting plate 15 that is arranged at the end of the guide rail 2. The material baffle plate 12 is arranged at one end of the guide rail 2 close to the inclined loading rack 3, the inclined plate 13 is arranged on the guide rail 2, and there are at least two speed limiting plates 15 that are symmetrically arranged along the vertical center plane of the guide rail 2. The speed limiting plate 15 can be deflected and arranged on the guide rail 2. The speed limiting plate 15 is transmission-connected to the clamping rod 10.

[0032] When using this cabinet metal plate rolling feeding device, first secure the mounting frame 1. Then, adjust the inclination angle of the guide rail 2 according to the specifications of the metal plates 6 to be processed, the position of the rollers, and other conditions. Then, place the stacked metal plates 6 on the lifting plate 8 within the inclined feeding frame 3. The lifting plate 8 slides upward, lifting the metal plates 6 to a position flush with the entrance of the guide rail 2 (during this process, the top metal plates 6 can contact the drive wheel 9 of the feeding conveyor mechanism 4 and the end of the clamping rod 10 of the clamping mechanism 5, allowing the drive wheel 9 and the clamping rod 10 to realize the discharge drive and clamping functions of the top metal plates 6). The upper metal plate 6 is moved to the position of the speed limiting plate 15, and the pressing rod 10 and the driving wheel 9 are driven at the same time. The pressing rod 10 is lifted up and separated from the surface of the metal plate 6 in contact with it, and the driving wheel 9 rotates to feed the metal plate 6. After that, the pressing rod 10 is reset and contacts the surface of the metal plate 6 of the next layer again, completing the cycle. When the metal plate 6 moves to the position of the single-layer unloading component 11, the blocking plate 12 blocks the lower metal plate 6, the inclined plate 13 guides the uppermost metal plate 6 to slide downward, and the reverse wheel 14 reversely drives the bottom of the lower metal plate 6 that may be driven synchronously, so that its movement direction is opposite to that of the upper metal plate 6, thereby realizing the separation function. If there is only a single-layer metal plate 6, since the driving force of the driving wheel 9 plus the driving force of the metal plate 6's own weight is greater than the reverse driving force of the reverse wheel 14, the single-layer metal plate 6 can still smoothly carry out the unloading operation, allowing the single-layer metal plate 6 to smoothly enter the guide rail 2. The metal plate 6 entering the guide rail 2 slides down along the guide rail 2 under its own gravity and the guidance of various components. The falling metal plate 6 reduces its speed under the restriction of the speed limiter 15, avoiding damage to the rolling equipment caused by excessive speed when running to the horizontal state, and ensuring that the metal plate 6 slides down steadily. Finally, the metal plate 6 passes the end of the guide rail 2 and reaches the roller position on the horizontal conveying platform, completing the feeding and preparing for rolling.

[0033] The feeding and conveying mechanism 4 and the pressing mechanism 5 of the present invention work together to ensure stable and accurate transmission of the metal plate 6, avoid problems such as deviation and simultaneous unloading of multiple layers of metal plates 6, and improve feeding efficiency. The overall structure is compact and the layout is reasonable, which saves space, reduces costs, and improves production efficiency.

[0034] The feeding transmission mechanism 4 also includes a wheel seat 16, a first telescopic rod 17, a first spring 18, a first rotating motor 19, a synchronous lifting frame 20, a rotating shaft 21 and a synchronous belt 22. The wheel seat 16 is elastically connected to the fixed plate 7 through the first spring 18, and the driving wheel 9 is mounted on the wheel seat 16. The first telescopic rod 17 is fixedly mounted on the fixed plate 7. The end of the first telescopic rod 17 is fixedly connected to the wheel seat 16. The first spring 18 is sleeved on the first telescopic rod 17. The synchronous lifting frame 20 is slidably set on the fixed plate 7. The synchronous lifting frame 20 is fixedly connected to the wheel seat 16. The first rotating motor 19 is fixedly mounted on the synchronous lifting frame 20. The rotating shaft 21 is rotatably set on the synchronous lifting frame 20. The output end of the first rotating motor 19 is fixedly connected to the rotating shaft 21. The rotating shaft 21 is connected to the shaft end of the driving wheel 9 through a synchronous belt 22. A first pressure sensor 23 for detecting the resistance pressure of the driving wheel 9 is provided on the wheel seat 16.

[0035] The wheel seat 16 is elastically connected to the fixed plate 7 via a first spring 18 and a first telescopic rod 17, and can adjust the height of the lifting plate 8 as needed until the pressure of the first pressure sensor 23 reaches a preset value before transmission is performed. This ensures that the metal plates 6 can be smoothly discharged toward the guide rail 2. After one layer is discharged, the lifting plate 8 rises again until the pressure value exceeds the preset value again before the discharge operation is performed, completing the discharge cycle. When the metal plates 6 need to be transported, the first rotary motor 19 drives the rotary shaft 21 to rotate, which in turn drives the drive wheel 9 to rotate via the synchronous belt 22. The drive wheel 9 elastically contacts the uppermost metal plate 6, and the friction force drives the metal plate 6 toward the guide rail 2.

[0036] One end of the inclined plate 13 close to the inclined loading rack 3 is hinged to the guide rail 2 through a hinge rod 24. A compression rod 25 is provided on the side wall of the inclined plate 13 away from the inclined loading rack 3. One end of the compression rod 25 is hinged to the guide rail 2, and the other end of the compression rod 25 is slidably engaged with the side wall of the inclined plate 13 through a first slider. A second spring 26 is sleeved on the compression rod 25.

[0037] When the metal sheet 6 moves to the inclined plate 13, the weight and inertia of the metal sheet 6 cause the inclined plate 13 to slide downward about the hinge point, compressing the compression rod 25 and storing energy in the second spring 26. Once the metal sheet 6 successfully passes through the inclined plate 13 and enters the guide rail 2, the second spring 26 releases its force, pushing the compression rod 25 back to its original position, which in turn drives the inclined plate 13 back to its initial position, ready for the next metal sheet 6 to pass through. This ensures the accuracy and continuity of single-layer unloading, improving the efficiency and reliability of the entire feeding device.

[0038] The speed limiting plate 15 is hinged to the guide rail 2 through the first deflection shaft 27. The axial direction of the first deflection shaft 27 is perpendicular to the inclination direction of the guide rail 2. The speed limiting plate 15 is fixedly connected to the first deflection shaft 27. A torsion spring 28 is provided on the first deflection shaft 27. The bottom end of the torsion spring 28 is fixedly connected to the first deflection shaft 27, and the top end of the torsion spring 28 is fixedly connected to the bottom of the guide rail 2.

[0039] When the metal plate 6 slides on the guide rail 2 and approaches the speed limiting plate 15, the metal plate 6 will push the speed limiting plate 15 to deflect around the first deflection axis 27, and the torsion spring 28 is twisted and stores energy during this process. After the metal plate 6 passes through the speed limiting plate 15, the torsion spring 28 releases its elastic force, driving the speed limiting plate 15 to return to its initial position, preparing to perform speed limiting control on the next metal plate 6. During this process, the kinetic energy of the metal plate 6 is absorbed by the speed limiting plate 15, and the speed of the metal plate 6 is reduced, so that it can run smoothly to the horizontal conveying platform, facilitating subsequent rolling work. The speed limiting plate 15 can be promptly restored to its initial position after each metal plate 6 passes, ensuring the continuity and accuracy of the speed limiting control and improving the operating efficiency and reliability of the entire feeding device.

[0040] The clamping mechanism 5 also includes a clamping anti-slip seat 29, a damping rod 30, a third spring 31 and a driving assembly. The clamping rod 10 is arranged vertically to the fixed plate 7. The clamping anti-slip seat 29 is fixedly installed at the bottom end of the clamping rod 10. The damping rod 30 is arranged between the clamping anti-slip seat 29 and the fixed plate 7. The two ends of the damping rod 30 are fixedly connected to the clamping anti-slip seat 29 and the fixed plate 7. The third spring 31 is sleeved on the clamping rod 10. The driving assembly is installed on the fixed plate 7. The driving assembly is connected to the clamping anti-slip seat 29 in transmission. The clamping anti-slip seat 29 is provided with a second pressure sensor 32 for detecting the clamping pressure.

[0041] The anti-slip seat 29 is used to directly contact and apply pressure to the topmost metal plate 6, so as to clamp the metal plate 6 to be fed in the lower layer, and at the same time prevent the metal plate 6 from shifting or tilting. The damping rod 30 is arranged between the anti-slip seat 29 and the fixed plate 7, and its two ends are fixedly connected to the two respectively, providing a certain damping force for the movement of the anti-slip seat 29, so that it can move smoothly when pressing and releasing the metal plate 6. The driving assembly is installed on the fixed plate 7 and is connected to the anti-slip seat 29 in transmission. Through the control of the driving assembly, the precise pressing and releasing action of the anti-slip seat 29 can be achieved. A second pressure sensor 32 is provided on the anti-slip seat 29 for real-time monitoring of the pressing pressure to ensure that the pressing force is within an appropriate range, so as to prevent the metal plate 6 from being deformed due to excessive pressure or loosened due to insufficient pressure.

[0042] The driving assembly includes a first linear driver 33, a push plate 34, a second slider 35, a retraction transmission rod 36 and a driving ring 37. The driving ring 37 is fixedly mounted on the anti-slip seat 29. One end of the third spring 31 is fixedly connected to the driving ring 37. The first linear driver 33 is fixedly mounted on the fixed plate 7. The fixed plate 7 is provided with a first sliding groove 38 for the second slider 35 to slide. One end of the retraction transmission rod 36 is hinged to the second slider 35, and the other end of the retraction transmission rod 36 is hinged to the driving ring 37. The push plate 34 is fixedly connected to the output end of the first linear driver 33, and the push plate 34 can be connected in contact with the second slider 35.

[0043] The first linear drive 33 is started, driving the push plate 34 to move along the first slide groove 38. When the push plate 34 moves to the position where it is in contact with the second slide block 35, the second slide block 35 is pushed to slide in the first slide groove 38. The second slide block 35 drives the retraction transmission rod 36 to deflect during movement, and then drives the driving ring 37 upward through the retraction transmission rod 36, so that the anti-slip seat 29 releases the pressing force on the metal plate 6. The push plate 34 is quickly reset after completing one push. At this time, the metal plate 6 is quickly unloaded under the drive wheel 9. During the unloading process, the anti-slip seat 29 is reset again under the elastic force of the third spring 31. The damping rod 30 is used to make the elastic force of the third spring 31 be released smoothly, preventing the anti-slip seat 29 from directly and quickly impacting the surface of the metal plate 6 and causing damage. The design of this driving component realizes precise control of the anti-slip seat 29, ensuring the stability and reliability of the metal plate 6 during the transmission process.

[0044] A resistance block 39 is fixedly mounted on the side wall of the speed limit plate 15 close to the vertical center plane of the guide rail 2 . A squeeze switch 40 cooperating with the resistance block 39 is provided at the edge of the guide rail 2 . The squeeze switch 40 is electrically connected to the first linear drive 33 .

[0045] When the metal plate 6 slides on the guide rail 2 and deflects the speed limiter plate 15, the speed limiter plate 15 drives the contact block 39 to move. When the contact block 39 contacts and compresses the squeeze switch 40, the squeeze switch 40 is triggered, which in turn electrically controls the first linear actuator 33 to activate or adjust its operating state. Based on the signal from the squeeze switch 40, the first linear actuator 33 precisely controls the retraction of the anti-slip seat 29 in the clamping mechanism 5, enabling the drive wheel 9 to transport the metal plate 6 beneath the anti-slip seat 29.

[0046] A long strip air blowing port 41 is horizontally installed on the baffle plate 12. The length direction of the long strip air blowing port 41 is consistent with the width direction of the guide rail 2. The opening direction of the long strip air blowing port 41 points to the inclined loading rack 3. The long strip air blowing port 41 is connected to the external high-pressure air source through an air pipe.

[0047] When the metal plate 6 is raised to a position flush with the inlet of the guide rail 2 and begins to move toward the guide rail 2, a high-pressure air source supplies air to the elongated air outlet 41 through the air pipe. Air is ejected from the elongated air outlet 41 and directed toward the stack of metal plates 6 on the inclined loading rack 3. At this point, the airflow has two main effects: first, it assists the drive wheel 9 and the clamping rod 10, making it easier for the top metal plate 6 to separate from the stack and move toward the guide rail 2; second, the airflow cleans dust, debris, and other impurities from the surface of the metal plate 6, preventing these impurities from affecting the subsequent rolling quality.

[0048] The end of the mounting frame 1 away from the guide rail 2 is provided with a displacement adjustment mechanism that is transmission-connected to the inclined loading frame 3. The displacement adjustment mechanism includes a base plate 42, a second linear drive 43, a second push rod 44, a sliding seat 45, a second deflection axis 46, a deflection transmission groove 47 and a fourth spring 48. The second linear drive 43 is fixedly mounted on the mounting frame 1. The output end of the second linear drive 43 is fixedly connected to one end of the second push rod 44. The other end of the second push rod 44 is hinged to the sliding seat 45. A second slide groove 49 for the base plate 42 to slide is provided on the mounting frame 1. The second deflection shaft 46 is located at one end of the base plate 42 away from the second linear drive 43. The inclined loading rack 3 is hinged to the base plate 42 through the second deflection shaft 46. The deflection transmission groove 47 is set on the inclined loading rack 3. The sliding seat 45 is slidably set in the inclined loading rack 3. One end of the fourth spring 48 is connected to the sliding seat 45, and the other end of the fourth spring 48 is fixedly connected to the bottom of the deflection transmission groove 47. A positioning rod 50 is provided on the side of the mounting frame 1 away from the second linear drive 43, and a positioning slot 51 matching the positioning rod 50 is provided on the base plate 42.

[0049] Initially, the tilting feeder 3 is horizontal, facilitating manual or robotic loading of the metal sheet 6. After loading is complete, the second linear actuator 43 is activated, its output driving the second push rod 44 to extend. This push rod 44 then pushes the sliding seat 45 to slide within the tilting feeder 3. As the sliding seat 45 moves, it first drives the base plate 42 along the second slide groove 49 on the mounting frame 1, achieving horizontal displacement of the tilting feeder 3. (Due to the elastic force, the thrust transmitted to the sliding seat 45 simultaneously drives the base plate 42 to move.) At this point, the tilting feeder 3 remains horizontal until the positioning slot 51 on the base plate 42 aligns and engages with the positioning rod 50 on the mounting frame 1. Once the positioning rod 50 engages with the positioning slot 51, the second linear actuator 43 continues to push the second push rod 44 to extend, causing the sliding seat 45 to continue sliding within the tilting feeder 3. At this time, the sliding seat 45 drives the inclined loading rack 3 to deflect around the second deflection axis 46, and at the same time the fourth spring 48 is compressed, so that the inclined loading rack 3 gradually changes from a horizontal state to an inclined state, preparing for the subsequent single-layer feeding of the metal plate 6.

[0050] This displacement adjustment mechanism cleverly solves the contradiction of facilitating loading while ensuring that the metal plate 6 smoothly tilts and slides down into the guide rail 2 in a limited space through a two-stage stroke design of horizontal displacement and angular deflection. During the loading preparation stage, the tilted loading rack 3 remains horizontal, which facilitates the placement of the metal plate 6, reduces the interference and difficulties of manual or robotic arms in placing the metal plate 6, and improves work efficiency and safety. During the loading stage, the working angle of the tilted loading rack 3 is quickly restored through angular deflection, and gravity is used to assist the metal plate 6 in sliding down, reducing the need for power transmission and achieving the goal of energy saving and consumption reduction. At the same time, the provision of the fourth spring 48 makes the angle adjustment process smoother and more controllable, avoids instability in the stacking of metal plates 6 or damage to the equipment due to sudden deflection, and improves the reliability and durability of the entire feeding device.

[0051] The inclined loading rack 3 is provided with a lifting drive mechanism, which includes a lifting motor 52, a screw 53, a threaded seat 54 and a limit rod 55. The lifting motor 52 is fixedly mounted on the bottom end of the inclined loading rack 3, the screw 53 is mounted on the inclined loading rack 3 and the length direction of the screw 53 is consistent with the tilting direction of the inclined loading rack 3, the output end of the lifting motor 52 is fixedly connected to the bottom end of the screw 53, the threaded seat 54 is fixedly mounted on one end of the lifting plate 8, and the other three ends of the lifting plate 8 are respectively slidably connected to the three limit rods 55, the limit rod 55 is fixedly connected to the inclined loading rack 3, and the screw 53 is threadedly connected to the threaded seat 54.

[0052] When the metal plate 6 needs to be lifted, the lifting motor 52 is started, driving the screw 53 to rotate. Since the threaded seat 54 is threadedly connected to the screw 53, and the other end of the lifting plate 8 is slidably connected to the limit rod 55, the rotation of the screw 53 is converted into a linear motion of the lifting plate 8 along the inclined loading rack 3, thereby gradually lifting the metal plate 6 to a position flush with the entrance of the guide rail 2.

[0053] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
