Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire packaging equipment, in particular to a device for wrapping film on enameled wire finished product stacks. Background Art

[0002] After the finished enameled wire is palletized, it is typically shipped by truck. Due to bumps and other factors during transportation, the entire stack of finished wires needs to be packaged and secured. Conventionally, this is done manually by wrapping stretch film around the finished wires. However, this packaging method is inefficient and labor-intensive. Therefore, to improve production efficiency, a stretch hood packaging machine is used. Existing stretch hood packaging machines use rolls of stretch hood film, which must first be made into bags, which are then stretched and placed over the product.

[0003] For example, the Chinese utility model patent with authorization announcement number CN205891430U discloses a cold-drawn shrouding machine, which consists of a frame and a film hanging assembly, a film feeding assembly, a heat-sealing and film-cutting assembly, a film opening assembly, a film drawing assembly, and a film shrouding assembly carried on the frame. The cold-drawn shrouding process is performed on a pallet through the actions of film feeding, film opening, heat sealing, film cutting, film collecting, film drawing, and film shrouding. However, the position of the pallet often deviates when it is transported to the shrouding machine, resulting in the film being unable to be accurately shrouded on the pallet. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0023] Example: Figure 1-5 As shown, a device for wrapping a whole stack of finished enameled wire products comprises a frame 1, a wrapping mechanism 2 arranged on the frame 1, and a conveying mechanism 3 arranged below the wrapping mechanism 2. The conveying mechanism 3 is mounted on the frame 1 via a slide rail 7. A first lifting assembly 4 for driving the conveying mechanism 3 to rise and fall is provided below the conveying mechanism 3. The first lifting assembly 4 uses a hydraulic cylinder, which is fixed to the ground or the lower end of the frame 1, and the upper end of the hydraulic cylinder is connected to the conveying mechanism 3.

[0024] The conveying mechanism 3 includes a conveying frame 301 and conveying rollers 302 linearly distributed on the conveying frame 301. The conveying rollers 302 are all powered rollers. The conveying frame 301 is installed on the frame 1 through the slide rail 7. The first lifting assembly 4 is arranged below the conveying frame 301.

[0025] A support platform 5 is provided below the film wrapping mechanism 2. Under the action of the first lifting assembly 4, the conveying surface of the conveying mechanism 3 can move up and down relative to the supporting surface of the support platform 5. Figure 2 and Figure 3 As shown, a plurality of support frames 501 are sequentially arranged on the support platform 5 along the conveying direction. The support frame 501 is located in the gap between two adjacent conveying rollers 302. A universal conveying ball 502 is provided at the upper end of the support frame 501. The universal conveying ball 502 is linearly distributed along the axial direction of the conveying roller 302.

[0026] like Figure 2As shown, a centering mechanism 6 is provided on both sides of the support platform 5 and is disposed on the frame 1. The centering mechanism 6 includes two centering arms 602 disposed on either side of the support platform 5, a mounting frame 601 fixed to the frame 1, a swing arm 603 hingedly connected between the centering arm 602 and the mounting frame 601, and a first cylinder 604 driving the swing arm 603 to swing. The swing arms 603 are disposed at the front and rear ends of the centering arm 602 and are arranged parallel to each other. The centering arm 602, the mounting frame 601, and the two swing arms 603 form a parallelogram structure.

[0027] The centering arm 602 is parallel to the conveying direction of the conveying mechanism 3 . A roller 605 is provided on the side of the centering arm 602 facing the support platform 5 . The rollers 605 are linearly distributed along the length direction of the centering arm 602 .

[0028] After the conveyor mechanism 3 delivers the entire stack of enameled wire (the enameled wire is placed on a tray) to the support platform 5, the first lifting assembly 4 drives the conveyor mechanism 3 downward, placing the entire stack of enameled wire on the support platform 5. The first cylinder 604 drives the swing arm 603 to swing, causing the two centering arms 602 to move closer together, aligning the entire stack of enameled wire on the support platform 5 to facilitate the next step of film coating.

[0029] like Figure 4 and Figure 5 As shown, the film covering mechanism 2 includes a film covering support 201, film pulling assemblies 202 arranged at the four corners of the film covering support 201, and a second lifting assembly 203 for driving the film covering support 201 to move up and down. The film covering support 201 is mounted on the frame 1 via a slide rail 7. The second lifting assembly 203 uses a sprocket and chain to drive the film covering support 201 to move, wherein the sprockets are distributed vertically, and the chain is wound around the upper and lower sprockets. The film covering support 201 is fixedly connected to the chain, and the sprockets are driven to rotate by a motor.

[0030] The film pulling assembly 202 includes a fixed seat 2021 fixed on the film support 201, a stretching arm 2022 slidably installed on the fixed seat 2021, a film pulling plate 2023 arranged at the inward end of the stretching arm 2022, and a second cylinder 2024 for driving the stretching arm 2022 to move. The second cylinder 2024 is connected between the fixed seat 2021 and the stretching arm 2022.

[0031] The film pulling plate 2023 is an arc-shaped plate. A suction cup 2025 is provided on the outward side of the film pulling plate 2023. A fan 2026 is provided on the stretching arm 2022. A connecting pipe is connected between the fan 2026 and the suction cup 2025. A through hole is provided in the center of the suction cup 2025, and the through hole is connected to the connecting pipe.

[0032] When the centering mechanism 6 completes the centering and sorting of the entire stack of enameled wires, the first lifting assembly 4 drives the conveying mechanism 3 to rise, lifts the entire stack of enameled wires from the support platform 5 and raises it to the set height, and then the film support 201 rises, so that the film pulling plate 2023 extends into the bag-shaped film above, and then the second cylinder 2024 operates to move the film pulling plate 2023 outward, stretching and unfolding the film, and at the same time the fan 2026 operates to cause the suction cup 2025 to adsorb the lower end of the film, and finally the second lifting assembly 203 drives the film support 201 to descend, and the film pulling plate 2023 drives the film to move downward until it is covered on the outside of the entire stack of enameled wires, completing the film covering action.
