Description

Technical Field

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

[0002] In the rolling process of cabinet metal plates, efficient feeding devices are the 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 it is easy to offset and jam, affecting continuity; the single-layer unloading component is poorly designed, and the unloading quantity cannot be accurately controlled, which can easily cause multiple layers of metal plates to enter the guide rail at the same time, causing blockage and damage to the equipment; the speed limit plate has limited adjustment ability 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 greater power to overcome the friction between the metal plate and the conveying surface, resulting in higher 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. As a potential energy-saving solution, inclined feeding 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.

[0018] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 - Fig.10The feeding device for rolling metal plates in a cabinet shown in the figure comprises a mounting frame 1, a guide rail 2, an inclined loading frame 3, a loading transmission mechanism 4 and a clamping mechanism 5. The guide rail 2 is arranged on the mounting frame 1 in an inclined and angle-adjustable manner. 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 consistent with the inclination angle of 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 transmission mechanism 4 is installed on one side of the fixed plate 7 close to the guide rail 2. The clamping mechanism 5 is installed on the other side of the fixed plate 7. The material conveying mechanism 4 includes a driving wheel 9 which elastically contacts the uppermost metal plate 6, the clamping mechanism 5 includes a clamping rod 10 which elastically contacts the uppermost metal plate 6, a single-layer material unloading component 11 is provided on the guide rail 2, the single-layer material unloading component 11 includes a material baffle plate 12 which is perpendicular to the inclination angle of the guide rail 2, an inclined plate 13 which is inclined to the guide rail 2, a reverse rotating wheel 14 which is arranged between the driving wheel 9 and the inclined plate 13, and a speed limiting plate 15 which 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 material loading rack 3, the inclined plate 13 is arranged on the guide rail 2, at least two speed limiting plates 15 are provided and are symmetrically arranged along the vertical center plane of the guide rail 2, the speed limiting plates 15 can be deflected and arranged on the guide rail 2, and the speed limiting plates 15 are transmission connected with the clamping rod 10.

[0020] When using this cabinet metal plate rolling feeding device, first fix the mounting frame 1, then adjust the inclination angle of the guide rail 2 according to the specifications of the metal plate 6 to be processed, the position of the roller and other conditions, and place the stacked metal plates 6 on the lifting plate 8 in the inclined feeding frame 3. The lifting plate 8 slides upward to lift the metal plate 6 to a position flush with the entrance of the guide rail 2 (in this process, the uppermost metal plate 6 can contact the driving wheel 9 of the feeding transmission mechanism 4 and the end of the clamping rod 10 of the clamping mechanism 5, so that the driving wheel 9 and the clamping rod 10 can realize the discharge drive and clamping functions of the uppermost metal plate 6). The uppermost metal plate 6 is moved to the uppermost metal plate 6 by the support 14, and the uppermost metal plate 6 is moved to the uppermost metal plate 6 by the support 14. 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 synchronously driven, so that it moves in the opposite direction to 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 due to excessive speed when running to a horizontal state, and ensuring that the metal plate 6 slides down steadily. Finally, the metal plate 6 reaches the roller position on the horizontal conveying platform through the end of the guide rail 2, completing the feeding and preparing for rolling.

[0021] The feeding transmission 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, the layout is reasonable, space is saved, costs are reduced, and production efficiency is improved.

[0022] 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 installed on the wheel seat 16. The first telescopic rod 17 is fixedly installed 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 arranged 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 installed on the synchronous lifting frame 20. The rotating shaft 21 is rotatably arranged 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.

[0023] The wheel seat 16 is elastically connected to the fixed plate 7 through the first spring 18 and the first telescopic rod 17, and can adjust the height of the lifting plate 8 according to the needs, until the pressure of the first pressure sensor 23 reaches the preset value before transmission, at this time, it is ensured that the metal plate 6 can be smoothly discharged toward the guide rail 2. After discharging one layer, the lifting plate 8 rises again until the pressure value exceeds the preset value again before discharging, realizing the discharging cycle. When the metal plate 6 needs to be transmitted, the first rotating motor 19 drives the rotating shaft 21 to rotate, and then drives the driving wheel 9 to rotate through the synchronous belt 22. The driving wheel 9 elastically contacts the uppermost metal plate 6, and drives the metal plate 6 to move toward the guide rail 2 through friction.

[0024] 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, and 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 matched with the side wall of the inclined plate 13 through a first slider, and a second spring 26 is sleeved on the compression rod 25.

[0025] When the metal plate 6 moves to the position of the inclined plate 13, under the action of the gravity and inertia of the metal plate 6, the inclined plate 13 will slide downward around the hinge point, and the compression rod 25 will be compressed accordingly, and the second spring 26 will be compressed to store energy. When the metal plate 6 successfully passes through the inclined plate 13 and enters the guide rail 2, the second spring 26 releases its elastic force, pushing the compression rod 25 to reset, thereby driving the inclined plate 13 to return to its initial position, ready to welcome the passage of the next metal plate 6. The accuracy and continuity of single-layer material feeding are guaranteed, and the operating efficiency and reliability of the entire feeding device are improved.

[0026] 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.

[0027] 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 in 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 the subsequent rolling work. The speed limiting plate 15 can be restored to its initial position in time 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.

[0028] 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 vertically arranged with respect to the fixed plate 7. The clamping anti-slip seat 29 is fixedly mounted 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. Both ends of the damping rod 30 are fixedly connected with 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 mounted on the fixed plate 7. The driving assembly is transmission-connected with the clamping anti-slip seat 29. A second pressure sensor 32 for detecting the clamping pressure is provided on the clamping anti-slip seat 29.

[0029] The anti-skid seat 29 is used to directly contact and apply pressure to the topmost metal plate 6, to clamp the metal plate 6 to be fed in the lower layer, and to prevent the metal plate 6 from deflecting or tilting. The damping rod 30 is arranged between the anti-skid seat 29 and the fixed plate 7, and the two ends are fixedly connected to the two respectively, to provide a certain damping force for the movement of the anti-skid 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-skid seat 29 in transmission. Through the control of the driving assembly, the precise pressing and releasing action of the anti-skid seat 29 can be achieved. A second pressure sensor 32 is provided on the anti-skid seat 29, which is used to monitor the pressing pressure in real time 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.

[0030] The driving assembly includes a first linear driver 33, a push plate 34, a second slider 35, a contraction 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 contraction transmission rod 36 is hinged to the second slider 35, and the other end of the contraction 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 with the second slider 35 in contact.

[0031] 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, it pushes the second slide block 35 to slide in the first slide groove 38. The second slide block 35 drives the contraction transmission rod 36 to deflect during movement, and then drives the driving ring 37 to move upward through the contraction 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 a 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 release smoothly to prevent 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.

[0032] A resistance block 39 is fixedly mounted on a side wall of the speed limit plate 15 close to the vertical center plane of the guide rail 2 . An extrusion switch 40 cooperating with the resistance block 39 is provided at the edge of the guide rail 2 . The extrusion switch 40 is electrically connected to the first linear drive 33 .

[0033] When the metal plate 6 slides on the guide rail 2 and pushes the speed limit plate 15 to deflect, the speed limit plate 15 drives the abutment block 39 to move. When the abutment block 39 contacts and squeezes the squeeze switch 40, the squeeze switch 40 is triggered, and then the first linear drive 33 is controlled to start or adjust the working state through electrical connection. The first linear drive 33 accurately controls the contraction action of the abutment anti-slip seat 29 in the clamping mechanism 5 according to the signal of the squeeze switch 40, so that the driving wheel 9 can transfer the metal plate 6 below the abutment anti-slip seat 29.

[0034] 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.

[0035] When the metal plate 6 is lifted to a position flush with the entrance of the guide rail 2 and starts to move toward the guide rail 2, the high-pressure air source supplies air to the long strip-shaped air outlet 41 through the air pipe. The airflow is ejected from the long strip-shaped air outlet 41 and directed to the stack of metal plates 6 on the inclined loading rack 3. At this time, the airflow has two main effects: on the one hand, the airflow can assist the driving wheel 9 and the clamping rod 10, making it easier for the top metal plate 6 to be separated from the stack and move toward the guide rail 2; on the other hand, the airflow can clean the dust, debris and other impurities on the surface of the metal plate 6 to prevent these impurities from affecting the subsequent rolling quality.

[0036] The end of the mounting frame 1 away from the guide rail 2 is provided with a displacement adjustment mechanism which 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. The mounting frame 1 is provided with a second slide groove 49 for the base plate 42 to slide. The second deflection axis 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 axis 46. The deflection transmission groove 47 is arranged on the inclined loading rack 3. The sliding seat 45 is slidably arranged in the inclined loading rack 3. One end of the fourth spring 48 is connected to the sliding seat 45. 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.

[0037] In the initial state, the inclined loading rack 3 is in a horizontal state, which is convenient for manual or mechanical arm to load the metal plate 6. After loading is completed, the second linear drive 43 is started, and its output end drives the second push rod 44 to extend, and the second push rod 44 pushes the sliding seat 45 to slide in the inclined loading rack 3. During the movement of the sliding seat 45, the bottom plate 42 is first driven to slide along the second slide groove 49 on the mounting frame 1 to achieve the horizontal displacement of the inclined loading rack 3. (Due to the elastic force, the thrust transmitted to the sliding seat 45 will synchronously drive the displacement of the bottom plate 42). At this time, the inclined loading rack 3 remains in a horizontal state until the in-position slot 51 on the bottom plate 42 is aligned and engaged with the in-position plug rod 50 on the mounting frame 1. After the in-position plug rod 50 is engaged with the in-position slot 51, the second linear drive 43 continues to push the second push rod 44 to extend, and the sliding seat 45 continues to slide in the inclined loading rack 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.

[0038] This displacement adjustment mechanism cleverly solves the contradiction of facilitating loading and ensuring that the metal plate 6 smoothly tilts and slides into the guide rail 2 in a limited space through a two-stage stroke design of horizontal displacement and angle deflection. In the loading preparation stage, the inclined loading rack 3 remains horizontal, which is convenient for the placement of the metal plate 6, reduces the interference and difficulties of manual or mechanical arms in placing the metal plate 6, and improves work efficiency and safety. In the loading stage, the working angle of the inclined loading rack 3 is quickly restored through angle deflection, and gravity is used to assist the metal plate 6 to slide down, reducing the demand for power transmission and achieving the goal of energy saving and consumption reduction. At the same time, the setting of the fourth spring 48 makes the angle adjustment process smoother and more controllable, avoids the instability of 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.

[0039] A lifting drive mechanism is provided on the inclined loading rack 3, and the lifting drive mechanism includes a lifting motor 52, a screw 53, a threaded seat 54 and a limit rod 55. The lifting motor 52 is fixedly installed at the bottom end of the inclined loading rack 3, the screw 53 is installed 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 installed 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.

[0040] When the metal plate 6 needs to be lifted, the lifting motor 52 is started to drive 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.

[0041] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
