AI Technical Summary
During the film rolling process, as the film thickness on the winding roller increases, the pressure of the pressing roller gradually increases, resulting in uneven rolling pressure during the film rolling, which easily leads to film damage.
A step-by-step winding device of the product inspection machine is designed, and the ball screw is driven by a servo motor to rotate, so that the winding seat moves from both sides to the middle to clamp the winding roller, and maintains the balanced state of the downward pressure of the roller cylinder and swing arm through the step lifting mechanism of the roller cylinder and the swing arm.
When the paper tube rolling thickness on the rolling roller increases, the pressing roller can be lifted step by step so that the pressure of the pressing roller is always maintained in an equalized state to avoid film damage.

[0002] During the film production and processing, the formed film needs to be inspected, and during the inspection process, the qualified film needs to be rolled up. In order to prevent wrinkles or looseness when the film is rolled up, a pressure roller is provided above the winding roller to facilitate rolling the film rolled up on the winding roller. The traditional pressure roller only controls the downward pressure of the pressure roller through a cylinder. In this form, as the film on the winding roller gradually thickens, the pressure between the film and the pressure roller gradually increases, which can easily cause uneven rolling pressure when the film is rolled up. At the same time, the gradually increasing pressure can easily damage the surface of the rolled film, so it still needs to be improved. Utility Model Content

A roller arm cylinder 12, wherein the roller arm cylinder 12 is mounted on a frame 19, a connecting cross bar is provided between the two roller arms 11, two sliding blocks are spaced apart on the connecting cross bar, a swing arm 17 is provided at the upper end of the sliding block, an L-shaped connecting rod 18 is provided at the lower end of the sliding block, a rotation node is provided between the end of the L-shaped connecting rod 18 and the sliding block and connected through the rotation node, a roller cylinder 6 is provided between the L-shaped connecting rod 18 and the swing arm 17, a rotation node is provided between the front end of the roller cylinder 6 and the front end of the L-shaped connecting rod 18 and connected through the rotation node, a rotation node is provided between the rear end of the roller cylinder 6 and the front end of the swing arm 17 and connected through the rotation node, and a roller 5 is provided between the two L-shaped connecting rods 18.
[0016] The turning frame is provided with a linear guide rail 8 , which is arranged at the bottom of the winding seat 3 . Turning beams 14 are provided at both ends of the turning frame. The turning beams 14 are connected with a cylinder 7 , which is installed on the frame 19 .
[0017] The sliding block is provided with a locking knob.
[0018] A variable frequency motor 1 is arranged on one side of one of the winding seats 3 .
[0019] The flip beam 14 is provided with a proximity switch 15 .
[0020] During use, the oil cylinder 7 pushes the flip beam 14 downward to make the winding seat 3 on the flip frame flip downward. After the winding seat 3 is close to the winding roller, the winding roller is placed between the two winding seats 3, and then the servo motor 2 drives the ball screw 4 to rotate, so that the two winding seats 3 move from both sides to the middle, thereby clamping the winding roller between the two winding seats 3, and then the oil cylinder 7 pulls the flip beam 14 upward to reset the winding seat 3 on the flip frame and the winding roller thereon. Then, the film is wound on the winding roller, and the frequency conversion motor 1 drives the rotating shaft on one of the winding seats 3 to rotate, thereby driving the winding roller to rotate and rewind. At this time, the pressure roller 5 will press the winding roller under the pressure of the pressure roller cylinder 6. The film on the winding roller is rolled, and as the film on the winding roller gradually thickens, the pressure roller 5 will be lifted up by the thickness of the film, and the pressure roller cylinder 6 will retreat backward, thereby driving the swing arm 17 and the L-shaped connecting rod 18 to lift upward. When the swing arm 17 is lifted upward to the limit position, it will drive the pressure roller arm 11 to passively lift upward. During this process, the pressure roller arm cylinder 12 will re-apply pressure to the pressure roller arm 11 after the pressure roller arm 11 is passively lifted. After the pressure roller 5, the pressure roller cylinder 6, the swing arm 17, the L-shaped connecting rod 18 and the pressure roller arm 11 step backward as a whole, the pressure roller cylinder 6 will push the pressure roller 5 forward, so that the pressure roller 5 rolls the winding roller again. This sequence is repeated, so that the rolling pressure of the pressure roller 5 on the winding roller is always kept in a balanced state.
[0021] The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and is easy to use. During the continuous winding process of the winding roller, the paper tube on the winding roller is lifted step by step as the winding thickness increases, so that the downward pressure of the pressure roller is always kept in a balanced state.
