Circulating film tearing device

Abstract

A circulating film-tearing device includes a main unit and a working unit. The main unit includes a main base plate and a plurality of rollers rotatably pivotally mounted on the main base plate. The working unit includes a drive source mounted on the main base plate, a movable plate that can be driven by the drive source to move back and forth relative to the main base plate, a glue platform mounted on the movable plate, and a plurality of receiving rollers rotatably pivotally mounted on the movable plate. A tape connected end to end passes through the glue platform, the receiving rollers, and the rollers along a winding path. By moving the glue platform driven by the movable plate, the tape can adhere to a corner of the film and be torn off. By moving the device further, the entire film can be removed. The length of the tape increases the adhesion area, significantly reducing the frequency of tape replacement.

Claims

1. A circulating film-tearing device for setting an end-to-end adhesive tape, comprising: a main unit including a main seat plate and a plurality of rollers rotatably pivotally mounted on the main seat plate; and a working unit including a drive source mounted on the main seat plate, a movable plate that can be driven by the drive source to move back and forth relative to the main seat plate, an adhesive platform mounted on the movable plate and extending obliquely forward and downward, and a plurality of receiving wheels rotatably pivotally mounted on the movable plate, wherein the adhesive platform, the receiving wheels, and the rollers are for the adhesive tape to pass through along a winding path.

2. The circulating film-tearing device as described in claim 1, wherein, The working unit also includes a positioning member disposed on the movable plate and corresponding to one of the receiving wheels. The positioning member can be controlled to protrude toward the corresponding receiving wheel, thereby cooperating with the receiving wheel to clamp the tape.

3. The circulating film-tearing device as described in claim 1, wherein, The main unit also includes a pressing wheel disposed on the main base plate and located on one side of the winding path, and a pressing member disposed on the main base plate and located on the other side of the winding path relative to the pressing wheel. The pressing member can be controlled to protrude toward the pressing wheel, thereby cooperating with the pressing wheel to clamp the tape.

4. The circulating film-tearing device as described in claim 1 further includes a control unit, wherein, The control unit includes a sensor disposed on the movable plate of the working unit and corresponding to the adhesive table. The sensor is used to confirm whether the tape wrapped around the adhesive table is adhered to an adhesive film and to peel off the adhesive film when the movable plate moves.

5. The reusable film-tearing device as claimed in claim 1 further includes a control unit, the tape having an adhesive section and a non-adhesive section connecting the adhesive section at both ends, wherein, The control unit includes a detector disposed on the main plate of the main unit and facing the winding path to detect the tape. The detector issues a warning signal when it detects that the non-adhesive section of the tape has passed through.

6. The recirculating film-peeling device as described in claim 5, wherein the transparency of the non-adhesive section is lower than that of the adhesive section, wherein, The detector of the control unit is located at the front and above the adhesive base. The detector detects the non-adhesive section through light transmittance or color detection.

7. The circulating film-tearing device as claimed in claim 1 further includes a control unit, the control unit including a tensioner disposed on the main seat plate of the main body unit and located on one side of the winding path, the tensioner having an actuation mechanism disposed on the main seat plate, a slide movably disposed on the main seat plate, and a tension wheel rotatably disposed on the slide and through which the tape is wound, the actuation mechanism being capable of driving the slide to reciprocate.

8. The circulating film-tearing device as claimed in claim 1, wherein, The main seat plate of the main unit has a mounting surface perpendicular to the rotation axis of the rollers, the moving plate of the working unit has a mounting surface parallel to the mounting surface and perpendicular to the rotation axis of the receiving rollers, and the rubber platform is vertically mounted on the mounting surface.

9. The circulating film-tearing device as described in claim 4, wherein, The working unit also includes a fixed gripper disposed on the movable plate and corresponding to the glue platform. The fixed gripper has a dynamic pressure cylinder and a fixing member connected to the dynamic pressure cylinder and driven by the dynamic pressure cylinder to move closer to or away from the glue platform.

10. The circulating film-tearing device as claimed in claim 9, wherein, The fixed gripper of the working unit also has a frame fixed to the moving plate and located on one side of the sensor, and the actuating cylinder is fixed to the frame.
