Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing component processing, and in particular to a high-efficiency strip cutting device for rubber sealing components. Background Art

[0002] Rubber seals are a common type of seal in the mechanical field. Their raw materials are rectangular rubber sheets. During the production process, the rubber sheets need to be cut into sections of rubber strips, and then the rubber strips are welded end to end to make sealing rings. This requires the use of strip cutting equipment for rubber seal processing.

[0003] For example, the authorization announcement number "CN218195430U" is named a rubber sealing ring processing cutting device, one end of the output shaft of the hydraulic cylinder is fixedly installed with an L-shaped plate, the front end of the L-shaped plate is movably connected with a movable block through a slide groove, and the top of the L-shaped plate is fixedly installed with a filter box. The rubber seal processing cutting device described in this utility model is convenient for pre-tightening the rubber ring, so that the cutting position is more accurate, and it is convenient to filter the gas generated by the rubber ring cutting. However, there is still a problem that the existing rubber seal processing cutting device uses a rotating cutting blade to fall down and then cut the rubber seal. However, in order to cut a complete rubber strip, the cutting blade needs to fall twice, and the two falls also require the blade cutting position to be positioned, so as to ensure that the rubber strips with similar specifications are cut out. However, this will waste a lot of time in the blade operation process and the adjustment of the cutting position, which ultimately affects the cutting efficiency of the rubber seal processing cutting device.

[0004] However, the above-mentioned device has disadvantages. Since the sealing ring is compressed and fixed by using a telescopic rod and a fixed plate, each time the rubber seal is cut into strips, the fixed plate needs to be lifted to change the position of the cut rubber seal strips. Therefore, too much manpower is wasted in the loading step of the rubber seal, and finally the feeding efficiency of the cutting equipment for rubber seal processing is reduced.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content

[0006] The utility model provides an efficient strip cutting device for rubber seals, which solves the problem in the related art that, because a telescopic rod and a fixing plate are used to compress and fix the sealing ring, the fixing plate needs to be lifted each time after the rubber seal is cut to change the position of the cut rubber seal strip, thus wasting too much manpower in the feeding step of the rubber seal, and finally reducing the feeding efficiency of the strip cutting device for rubber seal processing.
