Description

Technical Field

[0001] This utility model relates to a film roll flipping structure. Background Technology

[0002] In daily life, plastic film is a thin film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging or as a coating layer. During production, plastic film is wound into rolls, then packaged, transported, and sold. After the rolls of plastic film are produced, they are typically transported to the shipping area via conveyor belt. Then, the rolls are manually unloaded from the conveyor belt's output end, changing their orientation from horizontal to vertical and placing them on pallets. However, because the conveyor belt is at a certain height above the ground, and the rolls of plastic film are relatively heavy, repeated manual handling is time-consuming, labor-intensive, and inefficient. Furthermore, the rolls are easily damaged when being moved to the ground, affecting their quality. Utility Model Content

[0003] This invention addresses the aforementioned problems by providing a film roll flipping structure that is convenient to use and effectively reduces workload while improving work efficiency.

[0004] The present invention is constructed as follows: it includes a flipping assembly disposed at the output end of the conveyor belt. The flipping assembly includes a fixed frame and a rotating frame disposed above the fixed frame. The fixed frame and the rotating frame are hinged together. The rotating frame is driven by a driving device to flip along its hinge point.

[0005] Furthermore, the driving device includes a hydraulic cylinder disposed inside the fixed frame, the non-moving end of the hydraulic cylinder being hinged to the fixed frame, and the moving end of the hydraulic cylinder being hinged to a connecting plate disposed below the front end of the rotating frame.

[0006] Furthermore, the rotating frame includes a horizontal plate and a vertical plate disposed on one side of the horizontal plate. Two rows of rubber roller groups are symmetrically arranged in the middle of the horizontal plate, and each row of rubber roller groups consists of multiple rotatable rubber rollers.

[0007] Furthermore, the front part of the fixed frame is hinged to the front part of the rotating frame, and a support column is provided above the rear part of the fixed frame, with the rear part of the rotating frame abutting against the support column.

[0008] Furthermore, a fixing plate A is provided above the front of the fixing frame, and a fixing plate B is provided below the front of the rotating frame. The fixing plate A and the fixing plate B are hinged together by a pin.

[0009] Furthermore, each row of rubber rollers is inclined toward the middle of the horizontal plate, and the two rows of rubber rollers form an inverted V-shape.

[0010] Furthermore, the cross-section of the rotating frame is L-shaped.

[0011] Furthermore, the horizontal plate has two rubber roller mounting grooves in the middle, and the rubber rollers have rotating shafts at both ends, which are respectively rotatably engaged with the inner walls on both sides of the rubber roller mounting grooves.

[0012] Furthermore, the upper surface of the horizontal plate is flush with the upper surface of the conveyor belt.

[0013] Furthermore, a reinforcing rod structure is provided below the horizontal plate. The reinforcing rod structure includes multiple horizontal reinforcing rods spaced apart at the bottom of the horizontal plate along its length, and vertical reinforcing rods are provided between adjacent horizontal reinforcing rods.

[0014] Compared with existing technologies, this utility model has the following advantages: The device has a simple structure and reasonable design. When the conveyor belt transports the rolled plastic film, the rolled plastic film rolls onto the rotating frame, moving it to the horizontal plate of the rotating frame and contacting the rubber roller assembly. The hydraulic cylinder retracts, driving the rotating frame to slowly rotate along the hinge point, causing the entire rotating frame to rotate 90 degrees. During the rotation, under the action of gravity and the rubber roller assembly, the side of the rolled plastic film contacts the inner side of the vertical plate and is supported by the vertical plate, changing the horizontal state of the rolled plastic film into a vertical state for easier handling. Simultaneously, the rolled plastic film is moved closer to the ground, facilitating subsequent movement to the pallet by workers. This device has a simple structure, is easy to use, saves time and labor, greatly reduces the workload of operators, and improves work efficiency. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example: Figures 1-4As shown, in this embodiment, a film roll flipping structure is provided, including a flipping component disposed at the output end of the conveyor belt 1. The flipping component includes a fixed frame 2 and a rotating frame 3 disposed above the fixed frame. The rotating frame has an L-shaped cross section. The fixed frame and the rotating frame are hinged together. The rotating frame is driven by a driving device 4 to flip along its hinge point.

[0021] The front part of the aforementioned fixed frame is hinged to the front part of the rotating frame. A support column 5 is provided above the rear part of the fixed frame, and the rear part of the rotating frame abuts against the support column. A fixed plate A6 is provided above the front part of the aforementioned fixed frame, and a fixed plate B7 is provided below the front part of the rotating frame. The fixed plate A and the fixed plate B are hinged together by a pin.

[0022] During operation: When the conveyor belt transports the rolled plastic film 8, the rolled plastic film rolls onto the rotating frame, moving it to the horizontal plate of the rotating frame and into contact with the rubber roller assembly. The hydraulic cylinder retracts, driving the rotating frame to slowly rotate along the hinge point, causing the entire rotating frame to rotate 90 degrees. The horizontal plate, originally horizontal, becomes vertical, and the vertical plate, originally vertical, becomes horizontal. During the rotation of the rotating frame, under the action of gravity and the rubber roller assembly, the side of the rolled plastic film contacts the inner side of the vertical plate and is supported by the vertical plate, changing the horizontal state of the rolled plastic film into a vertical state for easy handling. At the same time, the rolled plastic film moves to a position closer to the ground, making it easier for subsequent workers to move it to the pallet. This device has a simple structure, is easy to use, saves time and labor, greatly reduces the workload of operators, and improves work efficiency.

[0023] In addition, existing hoisting equipment can be used to directly hoist rolls of plastic film onto pallets. First, the air shaft of the hoisting equipment is inserted into the through hole of the roll of plastic film, and then it is hoisted onto the pallet.

The moving end of the hydraulic cylinder and the connecting plate can be hinged via a pin.

[0025] In this embodiment of the utility model, the rotating frame 3 includes a horizontal plate 31 and a vertical plate 32 disposed on one side of the horizontal plate. Two rows of rubber roller groups 33 are symmetrically arranged in the middle of the horizontal plate, and each row of rubber roller groups consists of multiple rotatable rubber rollers.

[0026] The horizontal plate described above has two rubber roller mounting grooves 34 in the middle, and the rubber rollers have rotating shafts 35 at both ends, which are respectively rotatably engaged with the inner walls on both sides of the rubber roller mounting grooves.

[0027] The upper surface of the aforementioned horizontal plate can be flush with the upper surface of the conveyor belt to facilitate pushing the rolled plastic film on the conveyor belt onto the horizontal plate.

[0028] In this embodiment of the invention, in order to maintain the stability of the rolled plastic film and prevent it from rolling, each row of rubber rollers is inclined toward the middle of the horizontal plate, and the two rows of rubber rollers are in an inverted V-shape.

[0029] In this embodiment of the utility model, in order to improve the support strength of the horizontal plate, a reinforcing rod structure is provided below the horizontal plate. The reinforcing rod structure includes a plurality of horizontal reinforcing rods 10 spaced apart along the length direction of the horizontal plate at the bottom of the horizontal plate, and a vertical reinforcing rod 11 is provided between adjacent horizontal reinforcing rods.
