Description

Technical Field

[0001] This utility model relates to the field of soft plastic box processing technology, and in particular to an edge trimming device for processing soft plastic boxes. Background Technology

[0002] The utility model patent application CN222875111U discloses a "trimming device for processing plastic buckets". The device involves placing a plastic bucket on top of a placement tray, activating a telescopic rod, which pushes a rubber pad downwards until it contacts the bottom of the plastic bucket. This downward movement causes the placement tray to move a pressure plate downwards via a push rod, compressing a spring at the bottom of the pressure plate. Because the slider fixed to the outer wall of the scraper slides along a groove on the outer wall of the cross plate, the pressure plate, hinged to its outer wall, pulls the scraper, causing the four scrapers to converge and contact the outer wall of the plastic bucket, clamping it. The extension then stops. The motor is started by retracting the lever, and the telescopic lever fixedly installed at its output end begins to rotate. Due to the pressure between the rubber pad and the bottom of the plastic bucket, and the rotational connection between the placement plate and the push rod, the rubber pad causes the plastic bucket to rotate. The scraper clamped on the outer wall of the plastic bucket performs edge trimming work. After the trimming is completed, the motor stops working, and the telescopic lever is started, which drives the rubber pad to move upward. At this time, the spring is not compressed, pushing the pressure plate, push rod and placement plate upward, so that the connecting plate hinged to the outer wall of the pressure plate pushes the scraper. The four scrapers open and move, and the plastic bucket can be removed. This solves the problem that the existing edge trimming device requires clamping the plastic bucket first and then adjusting the blades, which is inconvenient to operate.

[0003] When the above only applies to rigid plastic buckets, and plastic buckets exhibit some flexibility or semi-flexibility, relying solely on rubber pads to press down the bottom of the plastic bucket, deformation can easily occur during the edge trimming process. Utility Model Content
