Description

Technical Field

[0001] This invention relates to the field of unwinding roll placement technology, and more specifically to an unwinding roll mounting platform. Background Technology

[0002] In modern stamping and related industries, unwinding platforms are key equipment for supporting and conveying fabric. Their main function is to provide stable support, ensuring that thin metal sheets can be smoothly unwound from the unwinding rolls for subsequent stamping, processing, etc.

[0003] The unwinding rollers wind up thin metal sheets to be processed, forming coils of a certain diameter. When placing the unwinding rollers onto the unwinding platform, a trolley is typically used to move the coil to the side of the platform, and then a chain hoist or manual jib crane is used to move the coil onto the support rollers of the unwinding platform. During the process of suspending the coil onto the unwinding platform, the hooks must be manually dragged to engage the unwinding rollers each time, and then gradually adjusted to align with the support rollers until installation is complete. This increases the workload for workers and also poses certain safety risks.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to design a method that allows the unwinding roller to be quickly moved to the unwinding platform for installation without the need for lifting equipment, thereby overcoming the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an unwinding roller mounting platform for mounting an unwinding roller, wherein a sheet to be processed is wound around the unwinding roller to form a material roll, comprising a frame, wherein symmetrically distributed lifting hooks are rotatably mounted inside the frame, one end of each lifting hook is fixedly mounted with a stop hook, and a lifting and translating module is also mounted inside the frame, wherein a support member is slidably mounted on the top of the lifting and translating module, and two rollers that cooperate with the unwinding roller are rotatably mounted on the support member;

[0007] The material roll is lifted by the contact between the lifting hook and the unwinding roller when the lifting hook rotates. The lifting and translation module drives the side of the support to fit with the outer circumference of the unwinding roller, pushing the unwinding roller to fit with the hook. When the material roll rises to a predetermined height, the support descends vertically. The lifting hook, which continues to rotate, drives the unwinding roller to move onto the two rollers.

[0008] Preferably, the lifting hook includes a first swing arm and a second swing arm rotatably mounted to the frame, with an obtuse angle between the first swing arm and the second swing arm, and the stop hook is fixedly connected to the end of the first swing arm, and the stop hook is perpendicular to the first swing arm.

[0009] Preferably, the support member includes an integrated support plate and a vertical plate, the height of the top surface of the support plate gradually decreases from the side away from the vertical plate to the side closer to the vertical plate, and the roller is rotatably mounted on the support plate.

[0010] Preferably, the lifting and translating module includes a scissor lift platform, a guide rail fixedly installed on the top of the scissor lift platform, a slider slidably installed on the top of the guide rail, and an electric telescopic rod installed on the guide rail. The output end of the electric telescopic rod is fixedly connected to the slider, and the support plate and the vertical plate are fixedly installed on the top of the slider.

[0011] Preferably, the scissor lift platform includes a base, two first rods and two second rods rotatably mounted on the base, a top plate rotatably mounted on the top of the first rods and the second rods, a connecting rod fixedly mounted between the two first rods, and a first hydraulic cylinder rotatably mounted between the connecting rod and the base. Adjacent first rods and second rods are rotatably connected at the middle, and the guide rail is fixedly mounted on the top of the top plate.

[0012] Preferably, a second hydraulic cylinder is rotatably mounted on the frame, and a transmission rod is rotatably mounted on the end of the output shaft of the second hydraulic cylinder. The two ends of the transmission rod are respectively rotatably connected to the ends of the two second swing arms.

[0013] Preferably, the connection between the first rocker arm and the stop hook has a rounded corner that matches the unwinding roller.

[0014] Preferably, the connection between the support plate and the slider has a rounded corner that matches the unwinding roller.

[0015] Preferably, the length of the portion of the vertical plate above the support plate is greater than the diameter of the unwinding roller.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. This invention, through the cooperation of the lifting hook, the blocking hook, the support component, and the lifting and moving platform, can quickly remove the material roll from the trolley and install it on the roller for support and unwinding. It eliminates the need for manual lifting equipment to install the material roll onto the platform, thereby improving installation efficiency, reducing the labor intensity of workers, and lowering the safety risks of using lifting equipment.

[0018] 2. In the initial state, when the lifting hook is facing diagonally downward, the lifting hook and the blocking hook can be used to lift the small diameter roll from the trolley. Then, with the cooperation of the lifting and moving platform and the support, the unwinding roller is gradually placed on the support. Finally, the lifting hook is driven to move the unwinding roller from the support to the roller.

[0019] 3. In the initial state, the lifting hook is facing diagonally upward. The lifting and moving platform and the support can push the unwinding roller to contact the lifting hook and the blocking hook. Then, the unwinding roller is gradually placed on the support, and the lifting hook is driven to move the unwinding roller from the support to the roller.

[0020] 4. When using this invention, it can be applied not only to rolls of different diameters, but also to unwinding rolls with radii not exceeding the stop hook and vertical parts, thus having a wide range of applications. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] This invention provides, for example Figure 1-7 The diagram shows an unwinding roller mounting platform for mounting an unwinding roller 1. The unwinding roller 1 has a sheet to be processed wound around it to form a roll 2. The platform includes a frame 3. Inside the frame 3, symmetrically distributed lifting hooks 4, each composed of a first swing arm 401 and a second swing arm 402, are rotatably mounted. An obtuse angle is formed between the first swing arm 401 and the second swing arm 402. A stop hook 5 is vertically mounted at the end of the first swing arm 401. The connection between the stop hook 5 and the first swing arm 401 has a rounded corner that matches the diameter of the unwinding roller 1. The length of the stop hook 5 is greater than the diameter of the unwinding roller 1. A transmission rod 10 is rotatably mounted between the ends of the two second swing arms 402. A second hydraulic cylinder 9 is rotatably mounted between the transmission rod 10 and the frame 3. When the output shaft of the second hydraulic cylinder 9 extends, as... Figure 3 As shown, the first rocker arm 401 and the second rocker arm 402 rotate counterclockwise, and rotate clockwise when the output shaft of the second hydraulic cylinder 9 is shortened.

[0034] Simultaneously, a base 6011 is fixedly installed inside the frame 3. Two symmetrically distributed first rods 6012 and two second rods 6013 are rotatably mounted on the base 6011. The middle portions of the first rods 6012 and adjacent second rods 6013 are rotatably connected to each other. A top plate 6014 is rotatably mounted on the ends of the first rods 6012 and adjacent second rods 6013. A connecting rod 6015 is fixedly installed between the two first rods 6012. A first hydraulic cylinder 6016 is rotatably mounted between the connecting rod 6015 and the base 6011. When the output shaft of the first hydraulic cylinder 6016 extends, the top plate 6014 rises vertically; when the output shaft of the first hydraulic cylinder 6016 shortens, the top plate 6014 descends vertically. At this time, the base 6011, the first rods 6012, the second rods 6013, the connecting rod 6015, and... The first hydraulic cylinder 6016 constitutes the scissor lift platform 601. A guide rail 602 is fixedly installed on the top of the top plate 6014. A slider 603 is slidably installed on the guide rail 602. A support member 7, consisting of a support plate 701 and a vertical plate 702, is fixedly installed on the top of the slider 603. A rounded corner is opened between the side of the support plate 701 away from the vertical plate 702 and the slider 603 to cooperate with the unwinding roller 1. An electric telescopic rod 604 is also fixedly installed on the guide rail 602. The output end of the electric telescopic rod 604 is fixedly connected to the slider 603, driving the slider 603 to slide horizontally on the guide rail 602. Here, the scissor lift platform 601, guide rail 602, slider 603 and electric telescopic rod 604 constitute the lifting and translation module 6, driving the support member 7 to move along the X and Z axes in the vertical plane.

[0035] In practical use, due to the varying thickness of the sheets, even with the same number of winding turns, the overall diameter of the roll 2 will change, resulting in a change in the height of the unwinding roller 1 relative to the ground. When the second hydraulic cylinder 9 drives the first rocker arm 401 to rotate until its top surface is parallel to the horizontal plane, if the height of the unwinding roller 1 on the ground is lower than the top surface of the first rocker arm 401, it is classified as a small roll. If it is higher than the top surface of the first rocker arm 401, it is classified as a large roll.

[0036] When installing the small roll, the lifting and translation module 6 first drives the support 7 to be lower than the small roll, and the second hydraulic cylinder 9 drives the first swing arm 401 to rotate to face downwards. Then, the existing trolley is pushed to move the roll 2 next to the frame 3, so that the unwinding roller 1 contacts the inclined surface of the first swing arm 401. At this time, the output shaft of the second hydraulic cylinder 9 shortens, and the first swing arm 401 gradually rotates clockwise. The unwinding roller 1 moves towards the stop hook 5 under the action of gravity. When the top surface of the first swing arm 401 is almost parallel to the horizontal plane, the lifting and translation module 6 drives the support plate 701 and the slider 603 of the support 7 to contact the unwinding roller 1. At this time, as the first swing arm 401 rotates, the support plate 701 moves accordingly, so that the unwinding roller 1 is suspended in the air. Then, the output shaft of the second hydraulic cylinder 9 stops shortening, and the lifting and translation module 6 drives the support 7 to slowly descend. Since the height of the top surface of the support plate 701 gradually decreases from the side away from the vertical plate 702 to the side closer to the vertical plate 702, when the height drops to a certain value, the unwinding roller 1 slowly rolls onto the support plate 701. At this time, due to the presence of the rollers 8, the unwinding roller 1 cannot move directly onto the two rollers 8 and remains in contact with the support plate 701. At this time, the output shaft of the second hydraulic cylinder 9 continues to shorten, driving the output shaft of the second swing arm 402 to rotate clockwise. The second swing arm 402 applies a lateral squeezing force to the unwinding roller 1, pushing the unwinding roller 1 onto the two rollers 8, thus completing the installation of the unwinding roller 1 from the trolley onto the rollers 8.

[0037] When installing the large roll, first drive the first swing arm 401 to face downwards, and drive the support 7 to be positioned below via the lifting and translation module 6. Then, push the roll 2 closer to the frame 3 via the trolley, and drive the first swing arm 401 to rotate clockwise upwards to a predetermined angle. Then, use the trolley to pull the roll 2 back a certain distance so that the unwinding roller 1 contacts the first swing arm 401. Then, drive the support 7 and slider 603 to contact the unwinding roller 1 via the lifting and translation module 6. After that, drive the support to push the unwinding roller 1 along the length of the first swing arm 401 until the unwinding roller 1 contacts the stop hook 5 and is suspended in the air. Then, drive the first swing arm 401 to rotate clockwise while driving the support 7, raising the unwinding roller 1 above the ground by a certain distance. The roller is suspended in the air. Then, the output shaft of the second hydraulic cylinder 9 stops shortening. The lifting and translation module 6 drives the support 7 to slowly descend. Since the height of the top surface of the support plate 701 gradually decreases from the side away from the vertical plate 702 to the side closer to the vertical plate 702, when the height drops to a certain value, the unwinding roller 1 slowly rolls onto the support plate 701. At this time, due to the presence of the rollers 8, the unwinding roller 1 cannot move directly onto the two rollers 8 and remains in contact with the support plate 701. At this time, the output shaft of the second hydraulic cylinder 9 continues to shorten, driving the output shaft of the second swing rod 402 to rotate clockwise. The second swing rod 402 applies a lateral squeezing force to the unwinding roller 1, pushing the unwinding roller 1 onto the two rollers 8, thus completing the installation of the unwinding roller 1 from the trolley onto the rollers 8.
