Description

Technical Field

[0001] This utility model relates to the field of metal coil feeding technology, specifically to a liftable feeding trolley for changing metal coils. Background Technology

[0002] With the continuous development of industrial automation technology, the manufacturing industry has increasingly higher requirements for production efficiency, product quality and cost control. In order to meet these needs, there is a need for equipment that can integrate processes such as uncoiling, leveling and feeding to achieve a high degree of integration and automation of the production process. The three-in-one feeding cart was born in this context. By integrating the three functions of uncoiling, leveling and feeding into one unit, it greatly reduces the floor space and optimizes the utilization of production space.

[0003] For example, application number CN201721490081.3 describes a coil feeding device for a slitting machine, comprising: a feeding roller for supporting the coil, with a long strip-shaped prefabricated groove provided on the ground on one side of the feeding roller; a feeding trolley located in the prefabricated groove for conveying the coil along the length of the prefabricated groove, the feeding trolley being provided with a support platform for carrying the coil; and a hydraulic cylinder mounted on the feeding trolley for driving the support platform to rise vertically so that the coil rises to the height of the feeding roller.

[0004] The limiting rod and the sleeve of the above-mentioned device are connected by a plug-in connection. This connection method makes the overall equipment unable to adapt to larger rolls of material, and the fixedly connected limiting rod cannot play a limiting role when dealing with smaller rolls of material. Utility Model Content

[0005] Given that the limiting rod and the sleeve of the above-mentioned device are connected by a plug-in connection, this connection method makes the overall equipment unable to adapt to larger rolls of material, and the fixedly connected limiting rod cannot play a limiting role when dealing with smaller rolls of material. To solve the above technical problems, this utility model provides the following technical solution: a liftable loading trolley for changing metal coils, comprising: a rectangular mounting base plate and I-shaped guide bars. A pair of symmetrical I-shaped guide bars are provided on the upper surface of the rectangular mounting base plate. The loading trolley is slidably connected to the I-shaped guide bars. Several hydraulic cylinders are disposed through the upper surface of the loading trolley. Arc-shaped blocks are fixedly connected to the extension rods of the hydraulic cylinders. Arc-shaped plates are provided on the vertical surfaces at both ends of the arc-shaped blocks. The loading trolley is also connected to a drag chain. A U-shaped guide frame is disposed through the vertical surface of the arc-shaped blocks. A T-shaped moving block is slidably connected to the inner ring of the U-shaped guide frame. A U-shaped guide bar is also provided on the vertical surface of the U-shaped guide frame. The U-shaped guide bar passes through and is slidably connected to the T-shaped moving block.

[0006] As a preferred embodiment of the liftable loading trolley for changing metal strips described in this utility model, a pair of T-shaped moving blocks are rotatably connected to the same cylindrical rod on opposite vertical surfaces, and a rectangular protective shell is installed on the vertical surface of the T-shaped moving blocks away from the cylindrical rod.

[0007] In a preferred embodiment of the liftable loading trolley for changing metal strips described in this utility model, a rotating rod is rotatably connected to the T-shaped moving block at the vertical plane away from the cylindrical rod. The rotating rod passes through the T-shaped moving block and is connected to the cylindrical rod. A docking rod is rotatably connected to the vertical plane of the T-shaped moving block. A gear column that is passed through the rod is fixedly connected to the body of both the docking rod and the rotating rod.

[0008] As a preferred embodiment of the liftable loading trolley for changing metal strips described in this utility model, a pair of gear columns are meshed, a drive motor is connected to the cross-section of the connecting rod, an installation frame is fixedly installed at the bottom of the drive motor, and a rectangular protective shell is fixedly installed on the vertical surface of the installation frame.

[0009] As a preferred embodiment of the liftable loading trolley for changing metal coils according to this utility model, a pushing groove is provided on the vertical surface of the arc-shaped plate, and a rectangular push block is slidably connected to the bottom surface inside the pushing groove. A pair of symmetrical hydraulic telescopic rods are installed on the vertical surface of the arc-shaped plate, and the extension rods of the hydraulic telescopic rods are fixedly connected to the rectangular push block. A mounting plate is fixedly connected to the vertical surface of the T-shaped moving block, and a mounting ring is fixedly connected to the upper surface of the mounting plate.

[0010] In a preferred embodiment of the liftable loading trolley for changing metal strips described in this utility model, the inner rings of a pair of mounting rings are each connected to the same push rod, and a rectangular push block is connected to the end of the push rod away from the mounting ring.

[0011] As a preferred embodiment of the liftable loading trolley for changing metal strips described in this utility model, a pair of circular rings are installed on the rods of the pair of cylindrical rods, and mutually symmetrical limiting rods are provided on the outer rings of the pair of circular rings.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. The cylindrical rod and limiting rod of this equipment are different from those in the above case. The cylindrical rod can be rotated. By rotating the cylindrical rod, the angle of the limiting rod can be changed, thereby guiding the roll material with different inner diameters.

[0013] 2. The distance between the cylindrical rod and the feeding trolley of this equipment can be adjusted. After the limit rod is guided, by adjusting the distance between the cylindrical rod and the feeding trolley, and by rotating the cylindrical rod again, the limit rod, which originally had an obtuse angle, becomes an acute angle, thereby supporting the roll material through the limit rod.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments. Example

[0019] Reference Figure 1-3This is the first embodiment of the present invention, which discloses a liftable loading trolley for changing metal strips, comprising: a rectangular mounting base plate 1 and I-shaped guide bars 2. A pair of symmetrical I-shaped guide bars 2 are provided on the upper surface of the rectangular mounting base plate 1. A loading trolley 3 is slidably connected to the I-shaped guide bars 2. Several hydraulic cylinders are provided through the upper surface of the loading trolley 3. Arc-shaped blocks 4 are fixedly connected to the extension rods of the hydraulic cylinders. Arc-shaped plates 5 are provided on the vertical surfaces at both ends of the arc-shaped blocks 4. The loading trolley 3 is also connected to a drag chain. A U-shaped guide frame 6 is provided through the vertical surface of the arc-shaped blocks 4. A T-shaped moving block 7 is slidably connected to the inner ring of the U-shaped guide frame 6. A U-shaped guide bar is also provided on the vertical surface of the U-shaped guide frame 6. The U-shaped guide bar passes through and is slidably connected to the T-shaped moving block 7.

[0020] A pair of T-shaped movable blocks 7 are rotatably connected to the same cylindrical rod 8 on opposite vertical surfaces. A rectangular protective shell 9 is installed on the vertical surface of the T-shaped movable blocks 7 away from the cylindrical rod 8.

[0021] The T-shaped moving block 7 is rotatably connected to the rotating rod 10 at the vertical plane away from the cylindrical rod 8. The rotating rod 10 passes through the T-shaped moving block 7 and is connected to the cylindrical rod 8. The vertical plane of the T-shaped moving block 7 is rotatably connected to the docking rod 11. The gear column 12 that is passed through is fixedly connected to the rod body of both the docking rod 11 and the rotating rod 10.

[0022] A pair of gear columns 12 are meshed together. A drive motor 13 is connected to the cross section of the connecting rod 11. A mounting frame 14 is fixedly installed at the bottom of the drive motor 13. A rectangular protective shell 9 is fixedly installed on the vertical surface of the mounting frame 14.

[0023] The loading process of the three-in-one feeding cart: Before loading, check the core components of the three-in-one feeding trolley, such as the uncoiler, support shaft, and tensioning device, to ensure they are in good working order and free from jamming, loosening, or damage. Adjust the tension range of the uncoiler support shaft, the width of the guide device, and the height of the load-bearing platform according to the specifications of the coil (width, diameter, weight, and material) to prevent the coil from colliding with the equipment during loading. Confirm that the power supply and control system (such as PLC) are in standby mode and that safety devices such as the emergency stop button are functioning properly.

[0024] The core feeding step involves moving the coil to the front of the feeding trolley 3 using auxiliary equipment (forklift or crane), aligning the center hole of the coil with the feeding trolley 3 to ensure that their axes are on the same straight line (excessive deviation will cause the coil to shake after feeding, affecting the subsequent feeding accuracy), and slowly lowering the coil until it fits against the feed plate (or positioning baffle) of the feeding trolley to ensure the axial position of the coil is stable. Then, the feeding trolley 3 is moved by a cable chain (before moving, the arc block 4 is raised to the appropriate position by a hydraulic cylinder).

[0025] When using this equipment, first confirm the inner diameter of the roll material during loading. Then, start the drive motor 13, as the drive motor 13 is connected to the cross-section of the connecting rod 11. Both the connecting rod 11 and the rotating rod 10 are fixedly connected with through-gear columns 12, which are meshed. A pair of cylindrical rods 8 are equipped with a pair of circular ring sleeves 20. Symmetrical limiting rods 21 are provided on the outer rings of the pair of circular ring sleeves 20. When the drive motor 13 rotates, the cylindrical rods 8 will rotate, causing the limiting rods 21, which were originally in a vertical state, to gradually begin to rotate. Eventually, the limiting rods 21 and the arc block 4 form an obtuse angle (the angle is adjustable and dynamically adjusted according to the inner diameter of the roll material). Then, the roll material can be placed on the arc block 4 using a forklift or crane. During the placement process, the limiting rods 21 can provide guidance and assistance for the roll material. Example

[0026] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a pushing groove 15 is provided on the vertical surface of the arc plate 5, and a rectangular push block 16 is slidably connected to the bottom surface inside the pushing groove 15; a pair of symmetrical hydraulic telescopic rods 17 are installed on the vertical surface of the arc plate 5; the extension of the hydraulic telescopic rod 17 is fixedly connected to the rectangular push block 16; a mounting plate is fixedly connected to the vertical surface of the T-shaped moving block 7; and a mounting ring 18 is fixedly connected to the upper surface of the mounting plate.

[0027] The inner rings of a pair of mounting rings 18 are connected to the same push rod 19. The end of the push rod 19 away from the mounting ring 18 is connected to a rectangular push block 16. A pair of cylindrical rods 8 are mounted on their bodies, and a pair of circular ring sleeves 20 are provided on the outer rings of the pair of circular ring sleeves 20. Symmetrical limiting rods 21 are provided on the outer rings of the pair of circular ring sleeves 20.

[0028] When using this device, first follow the operation described in Example 1. Then, start the hydraulic telescopic rod 17. Because the extension of the hydraulic telescopic rod 17 is fixedly connected to the rectangular push block 16, the vertical surface of the T-shaped moving block 7 is fixedly connected to the mounting plate, and the upper surface of the mounting plate is fixedly connected to the mounting ring 18. The inner rings of both mounting rings 18 are connected to the same push rod 19, and the end of the push rod 19 away from the mounting ring 18 is connected to the rectangular push block 16. The T-shaped moving block 7 will move. At this time, start the drive motor again to change the originally obtuse-angled limiting rod 21 to an acute angle. At this time, the protective layer on the limiting rod 21 will contact the arc surface of the roll material, so that the arc block 4 and the limiting rod 21 form a stable support structure, thereby supporting the roll material.

[0029] The remaining structure is the same as that in Example 1.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
