Problems solved by technology

In the process of opening the bag by the two bag-supporting boards of the charging device, if the maximum distance between the two bag-supporting boards is too large, the bag may be broken; if the maximum distance between the two bag-supporting boards is small, the There is a gap between the bag support board and the bag can easily slip off the bag support board
In production practice, due to the difference in the maximum opening of each bag in the same batch, it is easy to cause the bag to be broken or the bag to slip, and the charging efficiency is low, which reduces the production efficiency

Abstract

The invention relates to a bag propping-up mechanism. The bag propping-up mechanism comprises a mounting plate, two oppositely-arranged bag propping-up claws and a driving device. The two bag propping-up claws are separately fixed to both sides of the driving device through connecting pieces, and the spacing between the two bag propping-up claws is changed by the expansion and contraction of the driving device. The bag propping-up claws are provided with vacuum cavities, the bag propping-up claws are provided with a plurality of suction holes, and the vacuum cavities communicate with the suction holes. The vacuum cavities communicate with vacuum generators. The two bag propping-up claws are located in a bag, and air is sucked inwardly through the suction holes to enable the bag to be adsorbed on the outer walls of the bag propping-up claws. Meanwhile, an existing bag propping-up method is improved, a slightly opened bag opening is further opened by the bag propping-up claws, the bag isstably adsorbed on the bag propping-up claws through the suction holes, the bag is not prone to being broken caused by propping up or causing slipping of the bag, the structure is simple, the propping-up effect of the bag opening is good, the adaptability is high, and material loading is convenient.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a bag-stretching mechanism and a bag-stretching method. Background technique [0002] In the process of production and processing, it is often necessary to carry out loading operations on materials. In the existing loading operations, cylindrical film is often used for packaging, and double-layer cylindrical film packaging bags with three sides sealing are the most common. For the three-side sealed tubular film packaging bag, there are generally two methods in the existing enterprises: one is pure manual operation, that is, the bag is manually taken to the bottom of the discharge port, and the bag mouth is opened for loading. Time-consuming and labor-intensive; the other is to use machinery to send and pack bags through mechanical control, which has high work efficiency. [0003] The Chinese utility model patent application with the authorization number CN206511216U discloses ...
