Description

Manufacturing method of pre-opened zipper bag

Technical Field

The invention relates to a zipper bag, in particular to a manufacturing method of a pre-opened zipper bag, which is characterized in that a male buckle and a female buckle of a zipper part are pre-opened and then are pressed into segments in a pressing mode in the manufacturing process, so that the zipper part of a finished product is in a segment opening shape, and the purpose of time and labor saving in packaging is achieved.

Background

The zipper clamping bag is a packaging bag with a zipper clamping part at the opening end, the zipper clamping part comprises a male buckle clamping chain and a female buckle clamping chain which are respectively arranged on the two inner side walls, and when the male buckle clamping chain and the female buckle clamping chain are closed, dust and moisture can not penetrate through the zipper clamping part, so that the excellent protection effect on articles in the bag can be achieved; the zipper part can be opened and closed repeatedly, and the structure of the zipper part is not easy to be damaged, so that the zipper bag is widely and largely applied to the industry.

Then, the manufacturing of the zipper bag adopts a mass production mode, and most of the zipper bags are produced into semi-finished products and then cut and fused to complete the finished products of the zipper bags; the manufacturing method of the zipper bag semi-product can be seen from fig. 1, which comprises using a bag body extrusion mechanism to extrude a continuous tubular bag body 901, then using a zipper extrusion mechanism to extrude two male and female zipper chains Z1/Z2 on the surface of the bag body along the production line direction to be attached to the bag bodies 902-903, further using a cutting mechanism to cut out a sheet-shaped bag body 904 with an opening edge Z3, further using a turning mechanism to turn the bag body, and making the male and female zipper chains Z1/Z2 mutually buckled and positioned at the lower end of the opening edge Z3 to complete the manufacturing of the zipper bag semi-product 905. Since the male and female clip chains Z1/Z2 of the zipper bag semi-finished product 905 are fastened to each other, the zipper part Z of the cut and fused zipper bag finished product 906 will also be in a closed state, as shown in FIG. 2.

When the industrial industry uses the zipper bag to package objects, the male and female zipper Z1/Z2 of the zipper bag product 906 should be separated from the sealed state, and the open edge Z3 can be opened to insert the objects, as shown in FIG. 3; however, the two films of the opening edge Z3 are tightly adhered, and because the thickness is very thin, it is difficult for the operator to find a gap between the films and further exert a force to open the male and female clip chains Z1/Z2, so opening the opening edge Z3 of the finished zipper pack 906 is a nuisance. In the past, there are some people who use a zipper bag opening machine to open the zipper, such as taiwan patent number M584297; there are also some bags with a layer of frosted particles on the outside of the two films at the open end of the bag, and then the two films are staggered by pushing and rubbing with fingers to open the mouth of the bag, such as taiwan patent No. I644836. However, the bag opening machine using the zipper bag needs investment in equipment, and the frosted particle layer is disposed outside the two films of the zipper bag, which increases the manufacturing cost, and the greater problem lies in that the two methods cause the dislocation phenomenon of the two male and female buckle chains after the zipper part is opened, which not only makes the close connection of the zipper part difficult, but also the failure of the male and female buckle chains to make the articles in the bag unable to be effectively protected. The dislocation phenomenon means that the male buckle chain and the female buckle chain are not in the corresponding positions, so that when the buckling operation is performed, the male buckle chain cannot be smoothly inserted into the slot of the female buckle chain, and the corresponding position must be laboriously adjusted by an operator to affect the packaging efficiency.

Disclosure of Invention

As can be seen from the description of the background art, in the manufacturing process of the zipper bag semi-product, the two male and female zipper of the zipper part are formed and attached to the surface of the bag body synchronously in an extrusion manner, and in order to avoid the phenomenon that the male and female zipper are not easy to buckle due to dislocation in the finished product stage, the bag body must be turned over and the male and female zipper are buckled with each other in the manufacturing process; the zipper bag takes a zipper bag semi-product as a raw material, and the mutually sealed male and female buckle zipper becomes the characteristics of the existing zipper bag, so that the zipper part of the zipper bag is difficult to open when the zipper bag is used for packaging articles; therefore, the inventor thinks that if the zipper part is not closed when the zipper bag is delivered from the factory, the operator does not need to take effort to open the zipper bag; however, if the clamping chain part is in an open state when being delivered from a factory, how to overcome the phenomenon that the male and female clamping chains are dislocated is required; therefore, the zipper part is opened in advance in the process of manufacturing the zipper bag, and the dislocation of the male and female buckle zipper is avoided, so that the creation target established by the inventor is achieved.

Accordingly, the present invention is directed to a method for manufacturing a pre-opened zipper bag, which comprises separating a male and a female zipper of a zipper part, and applying a pressing manner to press both sides of the zipper part to open the central part of the zipper part and close both ends of the zipper part, thereby preventing the male and female zipper parts from being dislocated, and further achieving the purpose of saving labor and facilitating the packaging of articles.

In order to achieve the purpose, the invention makes the rolled semi-finished product of the zipper bag into the finished product of the zipper bag, and makes the center of the zipper part of the semi-finished product of the zipper bag open and the two ends of the semi-finished product of the zipper bag closed; the manufacturing method comprises the following steps: a. unfolding the zipper bag semi-finished product: continuously unfolding a roll-shaped zipper bag semi-finished product into a film-shaped zipper bag semi-finished product by a conveying unit, and enabling a section to be processed and formed to enter an operation area; b. prop apart public, box clip chain: a long tongue rod is inserted into the zipper part of the semi-finished product of the film-shaped zipper bag in the operation area and is kept in the continuously conveyed zipper part, so that the male buckle zipper and the female buckle zipper which are originally in a close state are separated from each other; c. moving the zipper bag semi-finished product: displacing the semi-finished product of the film-shaped zipper bag in the operation area by a clamping displacement unit to ensure that the displacement distance of the semi-finished product of the zipper bag reaches the width distance of the finished product of the zipper bag to be required; d. pressing the chain clamping part: pressing the male buckle clamping chain and the female buckle clamping chain which are in a separated state by a pressing jig at the rear side adjacent to the long tongue bar, so that the male buckle clamping chain and the female buckle clamping chain at the pressing position are sealed again; e. cutting and heat-sealing the cut end: cutting and fusing the central line position of the pressing part by a cutting and heat sealing unit to form a sealing edge on the cut part and separate the finished zipper bag product from the semi-finished zipper bag product; f. shaping and sealing edges: pressurizing the fused sealing edges by a shaping unit to shape and seal the two sealing edges; g. packaging the finished product of the zipper bag: the packaging bags are used for containing the finished zipper bags with rated quantity.

According to the characteristics of the invention, the incision, the heat sealing unit and the shaping unit work synchronously, so that two sealing edges are formed at the cutting position, and meanwhile, the sealing edges are shaped and sealed by pressurization.

According to the characteristics of the previous disclosure, the pressing fixture further operates synchronously with the notch, the heat sealing unit and the shaping unit, that is, one side of the operation area performs pressing operation, so that the male buckle clamping chain and the female buckle clamping chain at the pressing position are sealed again, and simultaneously the steps of cutting, heat sealing and shaping, sealing and sealing are performed at the pressing position at the other side of the operation area, so that the zipper bag finished product is separated from the zipper bag semi-finished product, and the shaping and sealing of the sealing edge are completed simultaneously.

The invention is characterized in that the long tongue bar extends into the continuously conveyed chain clamping part, so that the male buckle chain and the female buckle chain which are originally in a closed state are separated by the long tongue bar when passing through the long tongue bar; then a pressing fixture is used for pressing on the rear side of the long tongue bar, the separated male buckle clamp chain and the separated female buckle clamp chain are sealed again, the long tongue bar is spread in the clamp chain part, the pressed sections form a closed state, and the non-pressed sections spread by the long tongue bar form an open state; therefore, after the semi-finished product of the zipper bag entering the operation area is subjected to the operations of the supporting male and female buckle zipper in the step b and the pressing zipper part in the step d, the zipper part is in a segment closing state and a segment opening state; secondly, cutting and fusing the semi-finished product of the film-shaped zipper bag at the center line position of the pressing part through a cut and a heat sealing unit, and simultaneously forming two cuts into a sealing edge, wherein the cut I forms the outer side end of the semi-finished product of the film-shaped zipper bag, and the cut II forms a part separated from the semi-finished product of the film-shaped zipper bag; the invention also applies a shaping unit to carry out pressurized shaping and sealing on the two sealed edges, and the first side sealed edge and the second side sealed edge of the finished zipper bag are respectively formed by the first cut and the second cut.
