Description

Technical Field

[0001] The utility model relates to the technical field of rubber stopper production, in particular to a rubber stretching device for rubber stopper production. Background Art

[0002] Rubber stoppers are made of rubber materials, which have the advantages of dustproof, waterproof, wear-resistant, tear-resistant, aging-resistant, oil-resistant, ozone-resistant, etc. Therefore, they are widely used in various bottles and jars, covering the fields of medicine, household, biology, chemistry, etc. In the process of rubber stoppers production, they need to be stretched, so stretching equipment is needed;

[0003] During use, the existing stretching equipment usually clamps the rubber stopper and then uses the telescopic equipment to shrink it to complete the stretching test of the rubber stopper. However, in actual use, since the clamping point of the stretching equipment is fixed, but the model length of the rubber stopper is different, when the model length of the rubber stopper is less than the clamping point, the clamping limit work of the rubber stopper cannot be completed. In this way, the stretching test of the rubber stopper cannot be completed, which brings trouble to the staff. For this reason, we propose a rubber stretching equipment for rubber stopper production to solve the above problems. Utility Model Content
