Embodiment 1

[0073] The bag stretching device of the prefabricated bag packaging machine includes a translation mechanism 3 and a bag stretching mechanism 5 connected to the translation mechanism 3 , and the bag stretching mechanism 5 reciprocates along the material running direction under the action of the translation mechanism 3 .

[0074] It includes a translation mechanism and a bag stretching mechanism connected with the translation mechanism. The bag stretching mechanism reciprocates along the material running direction under the action of the translation mechanism. While the material is being conveyed, the prefabricated bag moves towards the material conveying direction through the stretching mechanism. , shorten the stroke, improve the packaging efficiency, and the bag stretching mechanism runs smoothly under the drive of the translation mechanism, without shaking, which can prevent the bag body from being damaged; it has a high degree of continuous material transportation, short tra...

Embodiment 2

[0076] The bag stretching device of the prefabricated bag packaging machine includes a translation mechanism 3 and a bag stretching mechanism 5 connected to the translation mechanism 3 , and the bag stretching mechanism 5 reciprocates along the material running direction under the action of the translation mechanism 3 .

[0077] The bag-opening mechanism includes a bag-opening claw fixedly connected to the translation mechanism 3 and a bag-opening cylinder 51 that drives the bag-opening claw to open or shrink. .

[0078] It includes the bag opening claw fixedly connected to the translation mechanism and the bag opening cylinder that drives the bag opening claw to open or shrink. The bag opening claw makes a linear reciprocating motion along the material running direction under the action of the translation mechanism, and the bag opening claw is driven by the translation mechanism. Movement, while the material is being conveyed, the prefabricated bag is stretched by the opening...

Embodiment 3

[0080] The bag stretching device of the prefabricated bag packaging machine includes a translation mechanism 3 and a bag stretching mechanism 5 connected to the translation mechanism 3 , and the bag stretching mechanism 5 reciprocates along the material running direction under the action of the translation mechanism 3 .

Abstract

The invention discloses a bag opening device of a prefabricated bag packaging machine, and belongs to the technical field of packaging machines. The bag opening device is characterized by comprising a translation mechanism and a bag opening mechanism connected to the translation mechanism, wherein the bag opening mechanism is driven by the translation mechanism to move back and forth in a material operation direction. According to the bag opening device, prefabricated bags are moved in a material conveying direction by virtue of the bag opening mechanism, so that the stroke is shortened, and the packaging efficiency is improved; moreover, the bag opening mechanism is driven by the translation mechanism to stably operate without shaking, so that the bags are prevented from being damaged; and the bag opening device has the characteristics of being high in material conveying continuous degree, short in conveying and packaging stroke, and high in material conveying and packaging efficiency.

Description

technical field [0001] The invention relates to the technical field of packaging machines, in particular to a bag stretching device of a prefabricated bag packaging machine. Background technique [0002] The packaging machine replaces the traditional manual packaging and has the characteristics of fast speed and neat and beautiful packaging. The packaging materials of the packaging machine can be candies, biscuits, paper towels, etc. Among them, the paper towel packaging machine is mainly used for the bagging and packaging of various specifications of soft paper towels. The paper towel packaging machines can be divided into: roll paper packaging machines, paper towel packaging machines, three-dimensional paper towel packaging machines, and wallet paper towels. Packaging machines, etc. Paper pumping packaging machines can be divided into three types: reciprocating packaging machines, three-dimensional packaging machines, and rotary packaging machines. [0003] In recent ye...
