Description

Wrapping paper sealing device and packaging paper sealing method using the same {The method and appratus for searing of wrapping paper}

The present invention relates to a wrapping paper sealing device and a wrapping paper sealing method using the same, and in detail, a wrapping paper sealing device for manufacturing a wrapping paper of a plastic sheet wound in roll shape to wrap vegetables in a vegetable corner in a large discount store or supermarket, and the like. It relates to a wrapping paper sealing method.

In general, when you buy vegetables in a vegetable corner such as a large discount store or supermarket, they are put in plastic bags without handles.

The plastic bag is rolled on the fabric in the form of a roll once the end of the hand by pulling and pulling out the plastic bag at the same time it is cut off and becomes a piece of plastic bag and put the vegetable into the inside through the cut opening sealing in the lower ( Heat-sealed), so that vegetables can be safely transported, so that housewives can conveniently separate vegetables from other foodstuffs and store them in shopping bags.

In order to manufacture such a roll-shaped vinyl wrapping paper, a lot of research has been made to automatically manufacture a device that continuously heats a certain interval, and continuously forms a tooth gap groove while supplying a double vinyl wrapping paper.

For example, Korean Utility Model Registration No. 20-0299193 discloses a plastic packaging bag including a fusion unit for fusion welding two layers of synthetic resin sheets in a transverse direction, provided between the supply unit and the fusion unit, There is described a vinyl bag manufacturing apparatus is installed is composed of a band sealer for fusion wide opening on the open side,

Publication No. 20-0277633, First and second to form a saw tooth having a sawtooth shape on the base plate connected to the lower end of the rod, and to move up and down, and a minute interval by the elastic force on both sides of the saw tooth A heat fusion portion is formed, wherein the first heat fusion portion is formed to have the same length as the cutting teeth, and the second heat fusion portion is provided in a separated form having a predetermined length at both ends of the cutting teeth, and the second The manufacturing method of the roll type vinyl shopping bag which consists of the operation head in which the cutting knife was formed in the inner end part of a heat-sealing part is described,

In the publication No. 1989-0003293, the cutting knife is spoken between operations, and the fabric conveyed to the upper surface of the cutting knife base is cut with the cutting knife and fused with a heating rod equipped with a heater to form a groove inside the cutting knife. Install the heat sink, and install the inclined rubber plate on the cutting knife base and compress it with the pressing plate, and the fabric cut by the cutting knife is spaced apart from the rubber plate by a certain distance and heat-bonded with the outer heat rod that is adjusted up, down, left and right with the adjusting bolt It describes a plastic bag heat adhesive cutting device in which the inner heat transfer rod is accumulated,

Korean Patent Publication No. 20-20-0302468 is a heat welding machine which is interposed above a cylinder block and forms a guide plate at one end and is interposed by a fixed hot wire interposed at the end of the cylinder block and the fixed hot wire and the support bar. Heater assembly consisting of a mobile heating wire that is connected through a rod and a shock absorber to perform fusion in up and down movement, a sensor for detecting the insertion of the plastic pack to one side of the mobile heating wire and the fixed heating wire, and the overall shape is roughly centered. Inside the recess groove formed in the inside, it is operated by the sensor and encloses the operation cylinder which promotes the up and down movement of the movable heating wire, and one side is equipped with a control that controls the operation of the overall heat welding machine such as the heater assembly and the operation cylinder. Maintain the cylinder block and the predetermined height, and place the cylinder block and heater assembly on the base The plastic pack heat fusion machine composed of predetermined support is disclosed,

In Korean Patent Registration No. 10-0192139, a line fusion unit having an upper mold and a lower mold with heating holes installed at regular intervals along a moving direction of a conveyor belt to form spot fusion and line fusion on a vinyl fabric.
