Description

Technical Field

[0001] This utility model relates to the field of roll film changing in strip packaging equipment, specifically a roll changing rotation mechanism. Background Technology

[0002] With the increase in output of strip packaging equipment and the increase in production time per roll of film, the demand for longer roll width and larger roll diameter has increased, and the main body of the roll film has become heavier accordingly.

[0003] Traditional strip packaging machines require manual film replacement by stopping the machine. Each replacement takes approximately 5-10 minutes, impacting production efficiency and equipment uptime. Furthermore, each film replacement necessitates removing the air shaft from the original roll and reinstalling it into the new film roll. The wider and heavier the film roll, the heavier the air shaft becomes, making installation difficult for a single person.

[0004] Furthermore, traditional strip packaging machines that use wide roll film require stopping the machine to replace the roll film. Currently, equipment that can automatically connect the film usually fixes the two rolls vertically or front and back, making it even more inconvenient to replace the roll film. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a roll changing and rotating mechanism to solve the above problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0007] A film-changing rotary mechanism includes a rotary device and a clamping device. The clamping device is disposed on the front and rear sides of the rotary device. The clamping device includes a sliding component, a telescopic component, a clamping bracket, and a clamping column. One end of the sliding component is connected to the rotary device, and the other end is connected to the clamping bracket and the telescopic component. The telescopic end of the telescopic component is connected to the clamping bracket. The clamping column is rotatably inserted and fixed inside the clamping bracket, which allows for free switching between the upper winding station and the working station. The film-changing station is always on the side that is convenient for film changing, simplifying the operation steps for changing to a new film roll. Furthermore, the clamping device clamps the film roll from both sides, and the brake provides braking force for the rotation of the clamping column and controls the tension of the film roll. Under these constraints, the film roll can be pulled normally, eliminating the need for the traditional bulky air shaft and reducing the manual burden.

[0008] Preferably, the rotating device includes a rotating shaft and a rotating platform, wherein the rotating shaft is fixed to one side of the rotating platform and aligned with the axis center.

[0009] Preferably, the telescopic component is a cylinder.

[0010] Preferably, the sliding assembly includes a guide rail and a slider. The guide rail is mounted on a rotary table, and one end of the slider is movably limited to the guide rail, while the other end is connected to a clamping bracket and a telescopic assembly.

[0011] Preferably, the clamping column is provided with a brake at its end.

[0012] Preferably, the clamping column has a boss in the middle.

[0013] Compared with the prior art, this utility model discloses a roll-changing rotating mechanism, including a rotating device and a clamping device. The two work together to achieve free switching between the upper winding station and the working station. The roll-changing station is always on the side that is convenient for roll changing, which simplifies the operation steps of changing to a new roll film. The clamping device clamps the roll film on both sides, and the brake provides braking force for the rotation of the clamping column and controls the tension of the roll film. Under such constraints, the roll film can be pulled normally, eliminating the traditional bulky air shaft and reducing the manual burden. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] A roll-changing rotary mechanism includes a rotary device 1 and a clamping device 2. The clamping device 2 is disposed on the front and rear sides of the rotary device 1. The clamping device 2 includes a sliding component 21, a telescopic component 22, a clamping bracket 23, and a clamping column 24. One end of the sliding component 21 is connected to the rotary device 1, and the other end is connected to the clamping bracket 23 and the telescopic component 22. The telescopic end of the telescopic component 22 is connected to the clamping bracket 23. The clamping column 24 is rotatably inserted and fixed inside the clamping bracket 23, and bearings are installed at corresponding positions.

[0019] The rotating device 1 includes a rotating shaft 11 and a rotating platform 12. The rotating shaft 11 is fixed to one side of the rotating platform 12 and aligned with the axis. The telescopic component 22 is a cylinder. The sliding component 21 includes a guide rail 211 and a slider 212. The guide rail 211 is mounted on the rotating platform 12. One end of the slider 212 is connected to the guide rail 211 in a movable limiting manner, and the other end is connected to the clamping bracket 23 and the telescopic component 22. The clamping column 24 is equipped with a brake at its end, which provides braking force for the rotation of the clamping column 24 and controls the tension of the film roll.

[0020] The clamping column 24 has a boss in the middle for abutting against the side of the core of the film. In this solution, the clamping column 24 is in the working mode of clamping from both sides, but the clamping column 24 can also be replaced with an air shaft of the same length, which provides tension from the inside to the outside of the air shaft while clamping. The choice can be made according to the actual working conditions.

[0021] Working mode: Two opposing clamping devices 2 form a group. A set of clamping devices 2 is provided on the upper and lower surfaces of the rotary table 12 to clamp the film rolls at the front and rear ends of the rotary table 12. The front end is the roll changing station and the rear end is the working station.

[0022] When the back-end film roll is used up, the drive motor drives the rotating shaft 11 to rotate, and the rotating table 12 rotates 180°. The front-end assembled film roll is moved to the back end to take over the work. The front-end telescopic component 22 is activated, which drives the guide rail 211 to move and open the clamping bracket 23. The operator removes the used film roll core and replaces it with a new film roll. After aligning the position, the two front-end telescopic components 22 are activated, which drives the guide rail 211 to move and close the clamping bracket 23. The clamping column 24 passes through the film roll core and provides clamping force at both ends of the film roll, completing the film roll replacement work. This process is repeated in sequence.
