Description

Technical Field

[0001] This utility model relates to the technical field of metal foil roll transfer devices, specifically to a metal foil roll sleeve clamping and lifting device. Background Technology

[0002] Metal foil rolls, including aluminum foil rolls, undergo multiple production processes, including slitting and cleaning, requiring a considerable amount of production equipment. Since aluminum foil rolls are typically wrapped around the outside of a sleeve, which is usually made of steel to support the roll, their weight necessitates transport via overhead cranes. However, the number of overhead cranes on a production site is limited, typically only one or two. In confined operating spaces, this interferes with the workflow and spatial arrangement. Manual lifting is even less efficient and poses safety hazards.

[0003] Therefore, it is necessary to develop a device that can smoothly and quickly transfer metal foil roll sleeves to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal foil roll sleeve clamping and lifting device to achieve fast and stable hoisting of metal foil rolls.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal foil roll sleeve clamping and lifting device, comprising a support frame, the support frame being provided with a sliding groove, the sliding groove being slidably connected to a sliding frame, the sliding frame being sequentially connected from top to bottom to a lifting component and a moving plate, the two ends of the moving plate being symmetrically hinged with grippers, the grippers being hinged to the output end of a piston rod, and the other end of the piston rod being disposed on the moving plate.

[0006] Furthermore, the sliding frame is equipped with a traveling wheel, which is slidably connected along the slide groove. The traveling wheel is connected to the output end of the transverse motor, and the slide groove is equipped with a displacement sensor.

[0007] Furthermore, the lifting assembly includes a scissor lift frame, with the upper and lower ends of one side of the scissor lift frame hinged to a moving plate and a sliding frame, respectively. The upper and lower ends of the other side of the scissor lift frame are provided with pulleys, and the moving plate and the sliding frame are provided with slots that fit the pulleys. The pulleys slide along the slots when the scissor lift frame is in operation.

[0008] Furthermore, the lifting assembly includes a lifting motor fixedly mounted on the sliding frame, the output end of the lifting motor is provided with a winch, one end of the winch is connected to a chain, and the other end of the chain is connected to the moving plate.

[0009] Furthermore, the gripper includes a U-shaped claw, one end of which has an opening is hinged to the movable plate, and the end of the U-shaped claw away from the opening extends along the width direction with a bent plate for receiving the sleeve. Connecting blocks extend from both sides of the U-shaped claw, and the piston rod is hinged to the connecting blocks.

[0010] Furthermore, a side connecting frame is provided between the movable plate and the piston rod. The non-output end of the piston rod is hinged to the side connecting frame.

[0011] Furthermore, a spring is fitted at the connection between the chain and the moving plate. One end of the spring abuts against the moving plate, and the other end of the spring abuts against a limiting plate. The limiting plate has a hole through which one link of the chain passes. The limiting plate is engaged by an adjacent chain link. The spring is used for shock absorption and buffering at the connection between the chain and the moving plate.

[0012] Furthermore, multiple C-shaped placement platforms are provided below the chute's travel path, which are used to temporarily store metal foil rolls.

[0013] Furthermore, a power distribution box is provided on the top surface of the sliding frame.

[0014] Furthermore, the sliding frame is connected to a cable chain, which moves in the same direction as the slide groove, and the cable chain is used to protect the circuit.

[0015] The advantages and beneficial effects of this utility model are as follows: 1. This utility model uses symmetrically arranged U-shaped claws driven by piston rods to connect the two ends of the foil roll sleeve. After the U-shaped claws close and engage the two ends of the sleeve, the bending plate can further fit against the two ends of the sleeve, stably clamping the metal foil roll sleeve to realize its loading, unloading, transfer, temporary placement and other operations.

[0016] 2. The scissor lift frame achieves stable lifting and lateral movement with a low center of gravity through the cooperation of pulleys and slots. The winch and chain structure provides high load capacity, while the chain limit plates and springs form a buffer to prevent sudden load impacts and reduce fatigue damage to key components. As the wheels move along the slide, displacement sensors provide real-time position information, which, combined with remote control operation, achieves high-precision horizontal positioning. Centralized control of lateral movement, lifting, and gripper actions via a distribution box results in a high degree of automation, reduced operational complexity, and improved work efficiency.

[0017] 3. The C-shaped platform below the chute facilitates temporary storage, and the storage of metal foil rolls is safe and stable; the drag chain follow-up protection circuit avoids cable wear or tangling, extending the equipment's lifespan.

[0018] 4. Through the industrial control board's communication interface, it can be connected to the factory's Internet of Things (IoT) system to achieve remote monitoring. And scheduling, suitable for intelligent production lines. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] Example 1 Please see Figures 1-6 The metal foil roll clamping and lifting device of this embodiment includes a support frame 1. A horizontal groove 11 is provided on the top of the support frame 1, and a sliding frame 12 is slidably connected within the groove 11. The sliding frame 12 engages with the groove 11 via wheels 13 at its bottom. The wheels 13 are driven by a transverse motor 14, enabling the sliding frame 12 to move horizontally along the groove 11. A displacement sensor 15 is also installed within the groove 11 to detect the position of the sliding frame 12 in real time.

[0022] A movable plate 3 is connected to the lower part of the sliding frame 12 via a scissor lift frame 21. The upper end of the scissor lift frame 21 is hinged to the sliding frame 12, and the lower end slides into the slot 23 on the top of the movable plate 3 via a pulley 22. The opening and closing of the scissor lift frame 21 is driven by a lifting motor 24: the lifting motor 24 is fixed to the sliding frame 12, and its output end, a winch 25, is connected to the movable plate 3 via a chain 26. When the lifting motor 24 rotates, the winch 25 retracts or extends the chain 26, causing the scissor lift frame 21 to extend or retract, thereby realizing the vertical lifting and lowering of the movable plate 3.

[0023] The movable plate 3 has symmetrically hinged grippers 31 at both ends. The grippers 31 are U-shaped, with the open end connected to the movable plate 3 via a hinge shaft, and the closed end extending into a curved plate 32 for supporting the sleeve of the metal foil roll. Connecting blocks 33 are provided on both sides of the grippers 31, and the connecting blocks 33 are hinged to the output end of the piston rod 34. The fixed end of the piston rod 34 is fixed to the movable plate 3 via a side connecting bracket 35. The extension and retraction of the piston rod 34 drives the grippers 31 to rotate around the hinge shaft, achieving clamping or releasing actions.

[0024] The working principle of this embodiment is as follows: First, the power supply of the transverse motor 14 is turned on, which drives the wheel 13 to move the sliding frame 12 to above the target sleeve. Then, the lifting motor 24 releases the chain 26, the scissor lift frame 21 unfolds, and the moving plate 3 descends. The PLC controller controls the piston rod 34 to extend, so that the gripper 31 opens and fits into both ends of the aluminum foil roll sleeve. Then, the piston rod 34 retracts, and the gripper 31 closes to clamp the sleeve. The lifting motor 24 tightens the chain 26, the scissor lift frame 21 retracts, and the moving plate 3 lifts the sleeve. The transverse motor 14 drives the sliding frame 12 to move to the placement position, completing the transfer of the sleeve.

[0025] Example 2 Based on Embodiment 1, a buffer mechanism is provided at the connection between the chain 26 and the movable plate 3. The end of the chain 26 passes through the mounting hole of the movable plate 3 and is fitted with a spring 27. One end of the spring 27 abuts against the movable plate 3, and the other end abuts against a limiting plate 28. The limiting plate 28 has holes that match the chain links and is fixed by snapping together with adjacent chain links. When the scissor lift frame 21 is subjected to impact load, the spring 27 compresses to absorb vibration and prevent the chain 26 from breaking due to overload.

[0026] Example 3 Multiple C-shaped placement platforms 16 are arranged at intervals along the movement path below the chute 11 for temporary storage of metal foil rolls. A cable chain 17 is connected to the side of the sliding frame 12. The cable chain 17 houses cables and air pipes and moves synchronously with the sliding frame 12, preventing cable entanglement and wear. The cable chain 17 runs parallel to the chute 11, further optimizing the spatial layout.

[0027] Example 4 In this embodiment, a power distribution box 18 is installed on the top of the sliding frame 12, which integrates an industrial control board, a power module, and a reversing valve. The traverse motor 14, displacement sensor 15, and lifting motor 24 are connected to the industrial control board via cables, and the pneumatic circuit of the piston rod 34 is controlled by the industrial control board through the reversing valve. The industrial control board is also wirelessly connected to a handheld remote control, allowing operators to send commands via the remote control to remotely control the clamping, lifting, and traverse movements.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
