Glass can opening device

Abstract

The invention provides a glass can opening device, and relates to the field of cans. The glass can opening device comprises a bottom sleeve base, wherein pressing rods are rotationally connected to the two ends of the bottom sleeve base, inner grooves of the bottom sleeve base are connected with jacking springs in a sleeving manner, the upper ends of the jacking springs are connected with extension clamping blocks, the extension clamping blocks are connected with the bottom sleeve base in a sliding mode, the upper end of the bottom sleeve base is fixedly connected with guide columns which areconnected with the extension clamping blocks in a sliding mode, the outer surface of each guide column is connected with an extension spring in a sleeved mode, the extension springs are connected withthe extension clamping blocks in a sliding mode, and height fixing plates are fixedly connected to the upper end of the bottom sleeve base and connected with the extension springs in a sliding mode.According to the glass can opening device, the extension springs are gradually compressed through the extension clamping blocks, so that a positioning ring slowly descends to get close to a bottle body, clamping plates are tensioned through clamping springs to be clamped and connected onto the surfaces of ratchet columns, and then the positioning ring is directly locked after descending and prevented from rebounding after clamping; and in this way, the problem that a glass can body cannot be fixed is solved, and the effect of fixing the glass bottle body is achieved.

Description

technical field [0001] The invention relates to the field of cans, in particular to an opening device for glass cans. Background technique [0002] Canning containers play an important role in the long-term preservation of canned food. Therefore, in order to ensure the quality of canned food, the materials used to make containers are usually non-toxic to the human body, have good sealing performance, and are required to have good mechanical properties and are not easily deformed. Soft material containers must not have stratification to facilitate processing, transportation, storage and sales. [0003] Glass bottle cans are usually used in daily life. However, when the cans are packaged and stored, the air pressure inside the bottle is usually reduced, which makes it difficult to open the can. Opening the bottle by thermal expansion and contraction will lead to deterioration of the internal food and rapid heating of the glass. There is a risk of breakage. The use of auxiliar...
