Description

Technical Field

[0001] The utility model relates to a winding device, in particular to a waste aluminum foil winding device. Background Art

[0002] During the production process of aluminum foil packaging bags, part of the aluminum foil is cut off at the edge as required. The cut-off aluminum foil is generally directly wound and treated as waste. However, some of the cut aluminum foil is relatively wide, and it is very wasteful to directly discard it. It can be used in the production process of square bags. Therefore, it needs to be neatly wound. During the cutting and conveying process of the aluminum foil, the edges will curl up, resulting in wrinkles when the winding roller winds, which affects the reuse of the cut aluminum foil. Therefore, only relatively flat aluminum foil can be wound for reuse. Summary of the Utility Model

[0003] In order to overcome the above deficiencies, the utility model provides a waste aluminum foil winding device that can ensure the flatness of the aluminum foil.

[0004] To achieve this purpose, the structure adopted by the utility model is as follows: a waste aluminum foil winding device, including a frame. A plurality of conveying rollers are arranged at the feeding port of the frame, and the conveying rollers convey the aluminum foil to a tension roller group. Two groups of winding groups are symmetrically arranged up and down on the frame. Each winding group includes a set of transition roller groups, two guide rollers and an air expandable roller. The air expandable roller is connected to a motor. A pressure frame is arranged between the air expandable roller and the guide rollers. A pressure roller is arranged on the pressure frame and contacts the air expandable roller. One side of the pressure roller is connected to the pressure frame through a swing arm, and a spring is arranged at the center of the swing arm and connected to the pressure frame.

[0005] A sleeve is arranged on the pressure frame, and a square shaft is arranged on the frame. The sleeve is sleeved on the square shaft to connect the pressure frame and the frame.

[0006] A proximity switch is arranged on the pressure frame, and the proximity switch is connected to the air expandable roller motor.

[0007] The filtering roller group includes a plurality of transition rollers, and the transition rollers are longitudinally arranged from top to bottom. The diameter of the transition rollers gradually decreases from the transition roller near the edge of the frame to the transition roller near the center of the frame.

[0008] The beneficial effects are as follows: The structure of the utility model is designed reasonably and ingeniously. The aluminum foil is conveyed from the conveying rollers to the tension roller group, and then passes through the transition roller group and the guide rollers and is wound on the air expandable roller. When winding, the pressure roller on the pressure frame presses the aluminum foil tightly on the air expandable roller, avoiding curling and wrinkling, making the collected aluminum foil flat and reusable.

[0014] As Figure 1 shown in the waste aluminum foil winding device, which includes a frame 1. A plurality of conveying rollers 2 are arranged at the feeding port of the frame 1, and the conveying rollers 2 convey the aluminum foil to the tension roller group 3. The tension roller group 3 includes a connecting plate, and a plurality of tension rollers are arranged on the connecting plate. The rear part of the connecting plate is connected to the frame 1 through a tension arm, and an oil cylinder is connected to the tension arm. Two sets of winding groups are symmetrically arranged up and down on the frame 1. Each set of winding groups includes a set of transition roller groups 4, two guide rollers 5 and an air-expanding roller 6. The air-expanding roller 6 is connected to a motor. A pressing frame 9 is arranged between the air-expanding roller 6 and the guide roller 5. A pressing roller 7 is arranged on the pressing frame 9 and contacts the air-expanding roller 6. One side of the pressing roller 7 is connected to the pressing frame 9 through a swing arm 8, and a spring 10 is arranged at the center of the swing arm 8 and connected to the pressing frame 9. The spring makes the pressing roller 7 always closely adhere to the aluminum foil on the air-expanding roller 6. The aluminum foil passes under the pressing roller 7 and then winds around the winding roller on the air-expanding shaft 6. When the aluminum foil passes through the pressing roller 7, the pressing roller 7 flattens the curled edge. After the aluminum foil winds around the winding roller on the air-expanding shaft 6, the pressing roller presses the aluminum foil tightly to prevent the outer layer of the aluminum foil from curling again due to insufficient pressure. The upper and lower two sets of winding groups can wind simultaneously or be conveniently replaced to ensure the winding efficiency.

[0015] A sleeve is provided on the pressure material rack 9, and a square shaft is provided on the machine frame. The sleeve is sleeved on the square shaft to connect the pressure material rack with the machine frame. When threading the material, the pressure material rack 9 can be removed. After the threading is completed, the pressure material rack 9 is sleeved on the square shaft, and the square shaft prevents it from rotating. Since the widths of different aluminum foil wastes are different, pressure rollers 7 with different lengths can be replaced as needed to match them.

[0016] A proximity switch is provided on the pressure material rack 9, and the proximity switch is connected to the motor of the air expandable roller 6. When the winding reaches a predetermined thickness, the air expandable shaft 6 stops rotating, and the aluminum foil roll is removed and replaced.

[0017] The filter roller group 4 includes multiple transition rollers, which are longitudinally arranged from top to bottom, and the diameters of the transition rollers gradually decrease from the transition roller close to the edge of the machine frame 1 to the transition roller close to the center of the machine frame 1. The transition roller groups 4 of the upper and lower two winding groups can be combined for use to extend the storage of aluminum foil and reduce the space occupation.

[0018] The structure of the utility model is reasonably and ingeniously designed. The aluminum foil passes through the conveyor roller to the tension roller group, then passes through the transition roller group and the guide roller and is wound on the air expandable roller. When winding, the pressure roller on the pressure material rack presses the aluminum foil tightly on the air expandable roller to prevent it from curling and wrinkling, making the collected aluminum foil flat and reusable.
