Embodiment 1

[0017] Embodiment one, such as figure 1 , figure 2 As shown, at the end of the 25W internal heating type electric soldering iron 1 soldering iron tip 2, a groove 3 with a depth of 5-10mm is opened downward by machining. The screw has a screw hole 5, and the inner wall of the screw hole 5 is provided with thread teeth. The commonly used stainless steel thin steel blade 4 is cut into the shape and size suitable for the groove, put into the groove 3, and screw in the screw hole 5. Insert the screw 6 to match the thread teeth, and the end of the screw 6 tightly fixes the thin steel blade 4 in the middle of the groove 3, thereby forming a simple cutting and sealing device.

Embodiment 2

[0018] Embodiment 2: A mercury switch connected in parallel with a diode is connected in series in the circuit of the electric soldering iron 1. When the electric soldering iron 1 is placed horizontally, the mercury switch is disconnected, and the electric soldering iron 1 is connected to electricity through the diode. At this time, the voltage of the electric soldering iron 1 is reduced by about half. , not only keep the soldering iron tip 2 at a certain temperature, but also save energy. When the soldering iron 1 is picked up, the mercury switch is turned on, and the soldering iron tip 2 can reach the working temperature soon, and start working again.

Abstract

The invention relates to a method for easily cutting and sealing a plastic bag. The method comprises: a common electric iron is adopted, a groove is inwards arranged on the top of the iron head of the electric iron in the mode of machine processing, and the depth of the groove is from 5 to 10 mm; a screw hole is made by a self tapping screw on one side of the iron head, screw teeth used for screwing the screw are arranged on the inner wall of the screw hole, and the screw hole is communicated with the groove; and a thin steel blade is inserted into the groove of the iron head, the side of the iron head is screwed into the screw hole through a small screw, and the thin steel blade in the groove is fixed on the inner wall of the groove in the vertical direction of the end part of the screw to form a simple cutting and sealing machine. The method has the advantages that the thin steel blade is arranged at the front end of the electric iron, the eclectic iron is heated after being supplied with power to make the hot and sharp blade cut the plastic bag along a steel rule, the cutting edge is tidy and smooth, and the cut is molten and sealed synchronously. The method not only is useful for collecting stamps, but also can be used for sealing and storing photos and pictures.

Description

Technical field: [0001] The invention relates to a method for simply cutting and sealing a plastic bag. Background technique: [0002] Many people like to collect stamps. The most important thing in stamp collecting is how to preserve stamps. The common practice is to put stamps in transparent plastic bags, which can have a sealing effect. Due to the different sizes of postage stamps, it is not easy to find matching plastic bags. Many people sometimes make small plastic bags by themselves for convenience. The more commonly used method is to heat and seal the pre-cut plastic bag through a saw blade. The disadvantage of this method is that it is not easy to control the operation, and the sealing position of the plastic bag is rough. Invention content: [0003] The technical problem to be solved by the present invention is to provide a method for cutting and sealing plastic bags by utilizing existing industrial product combinations. [0004] A kind of method for the simple ...
