[0021] The first embodiment of the present invention is a processing and forming device implementing the processing and forming method of the present invention, and its specific structure is as follows Figure 1 to Figure 5 shown.

[0022] The container bag cross forming device of the first embodiment includes a machine 10 , a hot pressing assembly 20 and a power assembly 30 for hot pressing the cross cloth corner 51 and the container bag cloth surface 50 . The cross has four cloth angles 51 in the first embodiment. For ease of description, the following upper / lower ropes are represented by ropes 60 .

[0023] The hot pressing assembly 20 includes a lower mold 22 and an upper mold 21 for folding the cloth corner 51 and cooperating with the lower mold 22 to clamp the cloth surface 50 of the container bag and the cross cloth corner 51 . The power assembly 30 provides driving force for the folding and clamping actions of the upper mold 21 . Both the lower mold 22 and the power...

[0029] The second embodiment is a method for processing a container bag cross, which uses the container bag cross processing and forming device of the first embodiment for processing. The processing method comprises the following steps:

[0030] Step A, put the upper cover cloth / lower base cloth that has been cut and processed on the positioning pile of the machine, and at this time, the four cloth corners have been partially curled up by the role of the positioning pile and the vault of the upper mold;

[0031] Step B, wrap the prepared upper rope / lower rope around the outside of the first three of the positioning piles in order, and the two ends of the upper rope / lower rope cross the inside of the second positioning pile and lead out , the size of the cloth angle lifting position is limited to the range of the square rope frame formed by the rope passing around the four positioning piles, and is controlled by the operator to tighten in the hand;

[0032] Step C, control the...

Abstract

The invention relates to a flexible freight bag feeding / discharging upper cover and lower bottom cross opening four-point positioning and forming method. According to the technical scheme, four positioning piles are wound by a rope at a time, four upper dies are driven by mechanical transmission so that four cloth corners can be mechanically unfolded at a time and subjected to heat pressure fusion forming through ultrasonic wave heating, and the technical defects existing in a process method that sewing is performed one by one, and then rope threading is performed are well overcome. Manpower sewing is replaced by a machine, production time is shortened, production efficiency is improved, production quality can keep stable for a long time, and influences of labor factors are avoided.

Description

technical field [0001] The invention relates to a container bag (flexible medium-sized bulk container) processing technology, in particular to a four-point positioning forming method for an upper cover and a lower bottom cross of an inlet and outlet material of a container bag. Background technique [0002] Container bag is one of many transportation packages. It is a flexible packaging container that can load 0.5 tons to 3 tons made of synthetic fiber or polyolefin materials through drawing, weaving, sewing and other processes. It is especially suitable for packaging in bulk. Cement, grain, chemical raw materials, feed, starch, minerals and other powder and granular objects are very convenient to load, unload, transport and store, and are very popular among enterprises. At present, the entire process of making container bags is basically made by manual sewing. How to improve the production efficiency has always been the work that container bag manufacturers are actively exp...
