< Industrial field > The present invention is a transparent plastic with environmentally friendly materials. After being pressurized ^ heated, the melted transparent plastic film is completed. At the same time, it is also formed as a movable pin and a fixed pin. After punching the small holes and wearing the zipper head, the same transparent plastic material of ^ guarantee material is also melted under pressure and heated to form a block that is consolidated with the solid insert, and a stopper is set at the front end of the zipper element. Each zipper cutting section performs a cutting action 'At this time, many substantial benefits such as rapid production, low cost, and no pollution to the environment are achieved.

When pressing the earliest pull button when making a metal box, the process steps (refer to Figure 1) are: (1) Setting the size, punching the chain teeth:, Set on the zipper semi-finished product A according to the desired zipper length, then The distance A 2 between each of the zipper semi-finished products A has been set. The zipper sprocket teeth are punched out and then the sprocket teeth are punched out (see Figure 2); (2) Ultrasonic wave film is applied: each zipper semi-finished product A has been punched out. About one-half of the teeth are above and below the film A1 (see Figure 3); (3) punching:

The semi-finished product A of each zipper is punched A2 at the position of the punched sprocket and above and below the film A1 (see Figure 4); (4) Wear the zipper head: Put the matching zipper head A 3 penetrates from the hole A 2 to the front end of the pull-button semi-finished product A (see Figure 5);

Description of the invention (2) (5) Clamping the box and the pin: The two blocks A 4 and the pin A 5 which are formed in combination are clamped to the two cloths at the position where the bottom end of the zipper semi-finished product A has hardened. Side inside A 1 〇 (as shown in Figure 6); (6) Fix the upper stop block: and fix the upper stop block A 6 at the front end of the sprocket A 1 1 inside the zipper, for the zipper A 3 to close by pulling the sprocket The stop stops pulling (see Figure 7); (7) Cut off:

Then cut at the cutting section of the set length of each zipper, which is the required pull button B (see Figure 8). Although the required zipper can be formed by the above-mentioned manufacturing method, the following defects are still felt in the production: First: high technicality> The box and the pin need to be aligned when clamped, and they need to be familiar with the operation Higher technology, otherwise it is easy to produce defective products and production is slow. Second: Poor firmness Because the blocks and pins are clamped directly, the pulling force is poor. If you are not careful, the blocks and pins can be easily loosened. ,

Third, the cost is because the blocks and pins are fixed to the bottom of the zipper by clamping. When you want to assemble, you need to store the blocks and pins first. In contrast, β consumes costs and occupies space. After that, some operators followed the same procedure for making zipper.% Square rope

(7) Cut: Then make the required zipper D (see figure 16) for each cutting section of a fixed length; the process of plastic injection molding of squares and pins, although the required zipper can be used However, there are still various shortcomings in the production. First, the cost is high. Because the plastic injection molding machine is expensive, the spare capital is huge, causing a heavy burden on the industry. Second: low production efficiency

Because of the plastic injection molding machine injection mode, after its hot and cold ejection, it needs to wait for its cooling before it can be combined with the cloth surface pressing. In addition, the production speed is too slow, which is inconsistent with economic benefits. Third: The high temperature molding is formed by the blocks and pins of the plastic injection molding machine. When the right side is directly set, the temperature of the blocks and pins after the mold is ejected is higher than two. It is very easy to damage the zipper sprocket made of nylon. And laminated cloth surface 4: Need to re-process the square and insert molding plastic products due to the injection, the surface is prone to produce excess burrs (because of the discharge port), if you are not careful, it is easy to scratch your hands. Furthermore, the excess burrs need to be removed by secondary processing. • Color change with a small amount of multi-color For the production of zipper of different colors, a large amount of injection at a time only matches

Description of the invention (5) In addition, injection 6: Utilize the temperature 〇 Based on the upper block molding square chain manufacturing design of the fixed-type plug with high production speed, which is the use of environmentally friendly materials without major changes Under the use of a section: First: It has ring economic benefits, but if it is small, it also causes production troubles. Zippers of different colors. The transparent molding (raw material) was 'easy to change color and produce the above-mentioned invention concept. The method of this case is the experience of intensive research and innovation', and then created a zipper block molding method, type, and the transparency of environmentally-friendly materials on fixed pins. Plastic and zipper cloth are fused and cured. In contrast, when the time is lowered, it will be divided into 4 colors. In addition to wasting colors, you need to change different colors often to make it expensive. When the transparency is poor, and It is easy to see that the bubbles are artificial and that they are new. The ultimate creation is mainly under the molding glue, which is added to improve the low cost. The solution is now to improve the cost of the film and activities that have been used for many years. Heating, production efficiency, but the environmental protection is based on its characteristics. The zipper is pulled down, and the solid, solid block is melted. It is also made of materials. It is described in terms of r. Features: because it is made of environmentally friendly materials, and In the fixed block, when it is renewed and discarded, it will be decomposed, which will not cause a loop. Second: reduce costs: Because it is not necessary to replace the whole cost-effectively, of course, greatly reduce demand The film and movable type, fixed and fixed under the insert, and the knot # will be contaminated by the environment after a period of time. Update, can take a single update, low 0
