Abstract

The invention discloses woven bag opening equipment. The woven bag opening equipment comprises a frame, and a bag support plate, a lower fixed rolling plate, an upper bag opening mechanism, a bag rolling mechanism and a lower bag pressing mechanism mounted on the frame; the upper bag opening mechanism includes an upper bag opening basal plate and an upper bag opening cylinder; the bag rolling mechanism includes a bag rolling basal plate, a bag rolling cylinder, an upper rolling plate, a bag rolling polyurethane pad, an upper bag pressing cylinder and an upper pressing block; and the lower bag pressing mechanism includes a lower bag pressing installation basal plate, a rotating cylinder, a lower bag pressing rotating shaft and a lower pressing block. The woven bag opening equipment can simulate a manual bag opening action, realizes the bag opening of rolling bags through the rolling plates, and can solve hot cutting and opening of woven bags; the rolling plates and the bags are in surface contact, so that the bag rolling principle is more reliable; and upper and lower bag openings are fixed and opened through pressing plates after rolling, so that the process is reliable.

Description

technical field [0001] The invention belongs to the field of woven bag opening equipment. Background technique [0002] In the field of automatic packaging production of solid materials, powders, etc. in bags, the bag opening process usually uses two sets of opposite suction cups to suck the two sides of the bag, and then pull them apart to realize the bag opening. Generally, this method can only deal with airtight bags. For non-coated woven bags, the use of vacuum suction cups for adsorption often requires a large flow rate, and the process is unreliable. [0003] In addition, because woven bags are usually hot cut when the bag is made, the hot cutting will cause the two layers of materials at the mouth of a bag to stick together, and some parts of the two layers of materials will stick together, which will cause it to open the bag Difficult to open with suction cups. [0004] Chinese patent application No. 201320428410.7 discloses a method for opening bags using adhesive...
