Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and in particular to a novel large plate feeding machine. Background Technology

[0002] In the sheet metal processing industry, the conveying of large sheets is one of the key links in the entire production process, directly affecting production efficiency, processing accuracy, and operational safety.

[0003] Traditional equipment has a simple clamping mechanism for large plates, which often uses simple clamping or simple locking methods, making it difficult to adapt to the fixing requirements of large plates of different thicknesses and materials. During the conveying process, the large plates are prone to loosening, shifting or even falling due to equipment vibration or start-stop impact, which may not only cause damage to the large plates but also pose a great safety hazard. In order to solve the above problems, this application proposes a new type of large plate feeder. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel large plate feeder. The limiting mechanism design of this feeder specifically solves the defects of unreliable clamping and poor adaptability in traditional equipment, achieving stable clamping of large plates. The hydraulic rod drives the first and second clamping plates to cooperate in clamping and fixing the large plate. Compared with the single-direction clamping or simple clamping methods of traditional equipment, the clamping force is more uniform and can adapt to the fixing needs of large plates of different thicknesses and materials. Limiting teeth are set on the contact surfaces of the two clamping plates, significantly increasing the friction with the contact surface of the large plate, effectively solving the problem of poor clamping effect of traditional clamping mechanisms on smooth-surfaced large plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel large plate feeder includes a base frame, a fixed plate fixedly connected to the inner top of the base frame, a motor fixedly connected to the side wall of the fixed plate, a sliding plate above the base frame, a moving mechanism between the motor and the sliding plate, a feeding frame fixedly connected to the top of the sliding plate, multiple equally spaced support bars fixedly connected to the top of the feeding frame, and multiple limiting mechanisms on the top of the feeding frame. Each limiting mechanism includes two mounting blocks fixedly connected to the top of the feeding frame, both mounting blocks being rotatably connected to a rotating rod. A second clamping plate is fixedly connected to the outer wall of the rotating rod. A first clamping plate cooperating with the second clamping plate is fixedly connected to the top of the feeding frame. A hydraulic rod is fixedly connected to the top of the feeding frame, and a lifting block is fixedly connected to the output end of the hydraulic rod. A through rod fixedly connected to the lifting block is passed through the lifting block. Two U-shaped grooves are formed on the second clamping plate, and corresponding through rods are arranged at both ends of the through rod.

[0006] Preferably, the moving mechanism includes a motor fixedly connected to the side wall of the fixed plate, the output shaft of the motor passing through the fixed plate and rotatably connected thereto, a first pulley fixedly connected to the end of the output shaft of the motor, a second pulley provided above the fixed plate, a synchronous belt being fitted together on the outer wall of the first pulley and the outer wall of the second pulley, a threaded rod being coaxially fixedly connected to the second pulley, the threaded rod passing through the sliding plate and threadedly connected thereto, and two guide rails fixedly connected to the top of the base frame, both of which are slidably connected to the bottom of the sliding plate.

[0007] Preferably, the base frame has a through opening, and the timing belt is arranged through the through opening.

[0008] Preferably, the top of the base frame is fixedly connected to two mounting seats, and the threaded rod passes through the two mounting seats and is rotatably connected to them.

[0009] Preferably, the bottom of the sliding plate is provided with a first protrusion that is fixedly connected, the threaded rod passes through the first protrusion and is threadedly connected to it, and the bottom of the sliding plate is fixedly connected with two second protrusions, which are respectively sleeved on the outer wall of the corresponding guide rail and slidably connected to it.

[0010] Preferably, the limiting mechanism is arranged between two support bars.

[0011] Preferably, the top of the first card plate and the bottom of the second card plate are provided with multiple limiting teeth, and the outer wall of the hydraulic rod is fixedly connected to two mounting brackets, both of which are fixedly connected to the top of the feeding rack.

[0012] Compared with the prior art, the advantages of this utility model are as follows: 1. The limiting mechanism of this feeder is designed to address the shortcomings of unreliable clamping and fixing and poor adaptability of traditional equipment, achieving stable clamping of large plates. The hydraulic rod drives the first and second clamping plates to cooperate in clamping and fixing the large plate. Compared with the single-direction clamping or simple clamping method of traditional equipment, the clamping force is more uniform and can adapt to the fixing needs of large plates of different thicknesses and materials. The contact surface of the two clamping plates is equipped with limiting teeth, which greatly improves the friction with the contact surface of the large plate and effectively solves the problem of poor clamping effect of traditional clamping mechanisms on smooth large plates.

[0013] 2. This feeder effectively solves the defect of large plates being easily deformed due to unreasonable support structure in traditional equipment by rationally designing the distribution of support components; multiple support components with equal spacing are used to jointly support the bottom of the large plate, so that the weight of the large plate is evenly distributed to each support point, avoiding the problem of uneven distribution of support points caused by the integral platform or excessively spaced support components in traditional equipment.

[0014] 3. This feeder, through its automated drive design, completely changes the current situation of cumbersome manual handling and traditional equipment operation, significantly improving production efficiency. The clamping mechanism adopts a power-driven method to achieve rapid clamping and loosening, replacing the manual adjustment method of traditional equipment. The operation process is simpler, and the time for fixing or disassembling a single large plate is significantly shortened. The moving conveying process is automatically controlled by a single drive source, eliminating the need for manual intervention. Compared with manual handling, it not only greatly reduces the labor intensity of operators but also avoids the problems of low efficiency and damage caused by manual handling.

[0015] In summary, the limiting mechanism design of this feeder specifically addresses the shortcomings of unreliable clamping and fixing and poor adaptability of traditional equipment, achieving stable clamping of large plates. The hydraulic rod drives the first and second clamping plates to cooperate in clamping and fixing the large plate. Compared to the single-direction clamping or simple locking methods of traditional equipment, the clamping force is more uniform and can adapt to the fixing needs of large plates of different thicknesses and materials. Limiting teeth are set on the contact surfaces of the two clamping plates, significantly increasing the friction with the contact surface of the large plate, effectively solving the problem of poor clamping effect of traditional clamping mechanisms on smooth-surfaced large plates.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-6 A novel large plate feeder includes a base frame 1, which serves as the basic support structure of the equipment, providing an installation reference and stable load-bearing for all components. A fixing plate 2 is fixedly connected to the inner top of the base frame 1, which is used to support and fix a motor 3. The motor 3 is fixedly connected to the side wall of the fixing plate 2, which provides driving force for the moving mechanism and is the power source for the movement of the sliding plate 8. A sliding plate 8 is provided above the base frame 1, which is used to support the feeding rack 10 and the large plate, and the feeding action is realized by moving.

[0020] A moving mechanism is provided between the motor 3 and the sliding plate 8. The moving mechanism includes the motor 3, which is fixedly connected to the side wall of the fixed plate 2. The output shaft of the motor 3 passes through the fixed plate 2 and is rotatably connected to it. A first pulley 4 is fixedly connected to the end of the output shaft of the motor 3. The first pulley 4 rotates synchronously with the output shaft of the motor 3 and transmits power to the second pulley 6 through the synchronous belt 5. The second pulley 6 is located above the fixed plate 2. The second pulley 6 receives the power transmitted by the first pulley 4 and drives the threaded rod 7 to rotate synchronously. The outer wall of the first pulley 4 and the outer wall of the second pulley 6 are fitted together with the synchronous belt 5. The synchronous belt 5 connects the first pulley 4 and the second pulley 6 to realize the power transmission and synchronous operation of the two. A through opening is provided on the base frame 1 to provide space for the synchronous belt 5 to pass through, so as to avoid interference with the base frame 1. The synchronous belt 5 is arranged through the through opening. The threaded rod 7 is coaxially fixedly connected to the second pulley 6. The threaded rod 7 converts the power into the linear movement of the sliding plate 8 by rotation. The power source, the top of the base frame 1, has two mounting seats fixedly connected. The mounting seats support and position the threaded rod 7, ensuring its stable rotation. The threaded rod 7 passes through the two mounting seats and is rotatably connected to them. The threaded rod 7 passes through the sliding plate 8 and is threadedly connected to it. The bottom of the sliding plate 8 has a first protrusion fixedly connected to it. The first protrusion, through its threaded engagement with the threaded rod 7, converts the rotational motion of the threaded rod 7 into the linear motion of the sliding plate 8. The threaded rod 7 passes through the first protrusion and is threadedly connected to it. The top of the base frame 1 has two guide rails 9 fixedly connected to it. The guide rails 9 provide guidance for the movement of the sliding plate 8, restricting it to move smoothly only in a set direction. Both guide rails 9 are slidably connected to the bottom of the sliding plate 8. The bottom of the sliding plate 8 has two second protrusions fixedly connected to it. The second protrusions are sleeved on the guide rails 9, enhancing the stability of the cooperation between the sliding plate 8 and the guide rails 9, ensuring smooth movement. The two second protrusions are respectively sleeved on the outer wall of the corresponding guide rails 9 and are slidably connected to them.

[0021] A feeding rack 10 is fixedly connected to the top of the sliding plate 8. The feeding rack 10 serves as the direct load-bearing structure for the large plate and is used to install support bars 11 and limiting mechanisms. Multiple support bars 11, evenly spaced, are fixedly connected to the top of the feeding rack 10. These support bars 11 collectively support the bottom of the large plate, distributing its weight and preventing deformation due to its own weight. Multiple limiting mechanisms are provided on the top of the feeding rack 10 to clamp and fix the large plate, preventing it from shifting or falling during feeding. The limiting mechanisms are arranged between two support bars 11, allowing them to specifically target the large plate on the support bars 11. To improve fixing accuracy, the limiting mechanism includes two mounting blocks 15 fixedly connected to the top of the feeding rack 10. The mounting blocks 15 provide rotational support for the rotating rod 14, ensuring the stability of its rotation axis. The two mounting blocks 15 are rotatably connected to the rotating rod 14, which provides a rotation center for the second clamping plate 13, allowing the second clamping plate 13 to rotate around it to achieve clamping or releasing actions. The outer wall of the rotating rod 14 is fixedly connected to the second clamping plate 13. The second clamping plate 13, through rotation, cooperates with the first clamping plate 12 to clamp or release the large plate. The top of the feeding rack 10 is fixedly connected to a device that matches the second clamping plate 13. The first clamping plate 12 and the second clamping plate 13 work together to limit the large plate from both sides. Multiple limiting teeth are provided on the top of the first clamping plate 12 and the bottom of the second clamping plate 13. These limiting teeth increase the friction with the large plate, enhance the clamping effect, and prevent the large plate from sliding. Two mounting brackets are fixedly connected to the outer wall of the hydraulic rod 16. These brackets securely mount the hydraulic rod 16 onto the feeding frame 10, ensuring its stability during operation. Both mounting brackets are fixedly connected to the top of the feeding frame 10, where the hydraulic rod 16 is fixedly connected. The hydraulic rod 16 provides driving force to the limiting mechanism. The extension and retraction drive the lifting block 17 to move. The output end of the hydraulic rod 16 is fixedly connected to the lifting block 17. The lifting block 17 transmits the extension and retraction motion of the hydraulic rod 16 to the through rod 18. The lifting block 17 is provided with the through rod 18 fixedly connected to it. The through rod 18 moves in the U-shaped groove 19, pushing the second clamping plate 13 to rotate around the rotating rod 14. The second clamping plate 13 has two U-shaped grooves 19. The U-shaped grooves 19 provide trajectory space for the movement of the through rod 18, so that the linear motion of the through rod 18 is converted into the rotational motion of the second clamping plate 13. The two ends of the through rod 18 are respectively arranged through the corresponding U-shaped grooves 19.

[0022] In this invention, the operator places a rectangular plate onto the feeding rack 10, supports the bottom of the plate on multiple support bars 11, and activates multiple hydraulic rods 16 to lower the lifting block 17 and the through rod 18. The through rod 18 moves downward within the U-shaped groove 19, causing the second clamping plate 13 to rotate around the rotating rod 14, thus opening the second clamping plate 13. The operator then places one side of the plate between the first clamping plate 12 and the second clamping plate 13. At this point, the operator activates the multiple hydraulic rods 16 to raise the lifting block 17 and the through rod 18. As the through rod 18 moves upward, it moves within the U-shaped groove 19, causing the second clamping plate 13 to rotate. The lever 14 rotates around the center, causing the first clamping plate 12 and the second clamping plate 13 to clamp and fix one side of the large plate, ensuring the stability of the large plate during subsequent feeding. (The external control system connected to the hydraulic lever 16 is programmed and controlled by a PLC (model: S7-200SMART) to achieve adaptive clamping, avoiding excessive clamping force that could damage the large plate or insufficient clamping force that could cause loosening. This technology is existing and will not be described in detail here.) The motor 3 is started, and the output shaft of the motor 3 drives the first pulley 4, the synchronous belt 5, the second pulley 6, and the threaded rod 7 to rotate. Under the guidance of the two guide rails 9, the sliding plate 8, the feeding frame 10, and the clamped large plate move, thereby completing the conveying and feeding of the large plate until it is delivered to the designated location.
