Description

Rubber ring trimming device

Technical Field

The utility model relates to the technical field of rubber ring processing, in particular to a rubber ring trimming device.

Background Art

Rubber ring is a common seal. During production, rubber ring needs to be pressed in a mold first. When the rubber molded product is vulcanized, the rubber quickly fills the mold cavity, and the excess part (in order to prevent lack of rubber, the rubber filled in the mold cavity should maintain a certain amount of interference) overflows, forming overflow glue, that is, flash. In order to make the product meet the specified size and ensure the appearance quality, the finished product after vulcanization needs to remove these excess rubber edges first. This process is commonly known as trimming.

Publication number: CN207656773U discloses a rubber ring trimming and cutting device, including a cutting device body, a sleeve rod and a cutting knife. A base is provided at the bottom of the cutting device body, a motor is fixedly connected to the middle position of the top of the circular support rod, the slide is slidably connected to the cutting knife through a slider embedded inside it, and a sleeve rod is provided on the surface of the base just below the fixed cylinder. In the utility model, a cutting knife is provided on one side of the bottom of the turntable, and the cutting knife is slidably connected to the turntable through the slide. The trimming radius of the cutting knife can be adjusted by moving the cutting knife on the slide. This structure can improve the trimming accuracy of the rubber ring. At the same time, the top center position of the turntable is connected to the motor through a transmission shaft. Through the transmission of the motor, the turntable rotates to carry the blade around the specified radius to perform efficient and accurate trimming and shearing of the rubber ring, which greatly improves the trimming efficiency and trimming quality.

The applicant found that there are some shortcomings in use: different diameters of rubber rings require different sleeve rod diameters, and the device is not convenient for replacing the sleeve rod. At the same time, since the diameter of the fixed tube is fixed, when a larger rubber ring needs to be trimmed, the fixed tube cannot clamp the rubber ring.

Therefore, the utility model designs a rubber ring trimming device to solve the problems existing in the prior art.
