Device for measuring full-shape roll hem of top cover on aerosol can

Abstract

The invention discloses a device for measuring a full-shape roll hem of a top cover on an aerosol can. The device is composed of a calliper A, a calliper B and a top cover inlet C. The device is characterized in that the calliper A, the calliper B and the top cover C are connected for forming a snapping trough; the snapping trough comprises an upper snapping trough 3, a middle snapping trough 2 and a lower snapping trough 1; the dimension of the lower snapping trough A1 of the calliper A is the lower limit value of the standard value of the external diameter of the top cover port opening on the aerosol can; the dimension of the lower snapping trough B1 of the calliper B is the upper limit value of the standard value of the external diameter of the top cover port opening on the aerosol can;and the shape of the upper snapping trough 3 is same with the full-shape roll hem of the top cover. The device for measuring a full-shape roll hem of a top cover on an aerosol can has the following beneficial effects of 1, through reasonably designing the dimensions, shapes and heights of the two callipers, whether the external dimension, the roll hem shape and height of the top cover on the aerosol can reach the standard can be determined quickly and visually; 2, simple structure is realized, the device is suitable for an aerosol can production streamline, and furthermore detecting time saving and production efficiency improvement are realized.

Description

Technical field [0001] The invention relates to a device for measuring the upper cover of an aerosol can, in particular to a device that can measure the full shape of the upper cover of an aerosol can without damage and quickly. Background technique [0002] With the rapid development of the aerosol industry, aerosol products have entered the homes of ordinary people by virtue of their flexible and simple construction advantages. China has become a major aerosol producer, driving the domestic three-piece or part of the two-piece aerosol The number of can production enterprises increased rapidly. Different aerosol manufacturers have launched active production competition, producing various high-performance aerosol products to meet the needs of the industry. Aerosol cans are the basic industry for the production of aerosol products. Three-piece aerosol cans are usually composed of a can body and upper and lower covers; some two-piece aerosol cans are usually composed of a can body...

AI Technical Summary

Problems solved by technology

However, the method of using a vernier caliper to test whether the outer diameter of the top cover can reach the standard takes a long time to test, and it is impossible to quickly and intuitively judge whether the top cover of the aerosol can meets the standard, which seriously affects the smoothness of production.
