The value of the package. At present, there are two methods for manufacturing plastic shrink film: The first one is a 模-type mold extrusion manufacturing method, which is performed by extruding a Τ-type mold to extrude an unstretched flat film, and the chilling device is used to cool the valley mouth, and then it is subjected to heat waves. The wheel set and the large and complicated heat extension machine (Tenter) are longitudinally extended and laterally extended, cooled by the cold valley roller set, and finally taken out from the take-up mechanism, and the pick-up mechanism is taken up and stored. Although this method of manufacture can be made into the original plastic shrink film, it has the main drawbacks of its underarms: its mechanical equipment is complex and huge, and the wood only needs to invest in a large field and machinery and equipment, and the cost of the bear is extremely high. However, the product to be produced is not covered by the clamp member, and it must be cut off to form waste (about 15%), which is a waste of cost, and is particularly unsuitable for a small variety of products. 5 1273024 The second manufacturing method is a blown film forming method, which is also a conventional method of small-scale and low-cost extrusion blown film forming, which cannot be used as a plastic shrinkage polystyrene ( PS) to form and manufacture * Up to now, there has not been a film blowing method to make a shrink film tube. SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned conventional squeezing method. The apparatus for manufacturing a plastic film tube is complicated and large, and the investment is high, the energy consumption is large, and the finished product waste is large; The lack of the blown film forming method is that the polystyrene (PS) is used as a raw material to form a shrink film tube, and the present invention provides a blown film forming manufacturing method and device for a polystyrene (PS) plastic shrink film tube. This manufacturing method and device is the inventor's practical experience in the operation and manufacture of various plastic films. After years of research and development and continuous exploration and improvement, the inventors are made of polystyrene (PS^ plastic as raw material, using extruding mechanism). The membrane tube is made into a cylindrical shape, and after being cooled, the membrane tube is uniformly heated by a special-stage hot water device by a multi-stage pressure guide wheel set to soften the membrane tube, and then the air pressure is added to the softened membrane tube. And adjusting the difference in the speed of the front and rear pressure guide wheel sets, the original thick plastic film tube is laterally expanded and longitudinally extended to become a thinner stretch film tube, and then passed through a processing device. The shaped spikes are fixed into the shaped film tube. Finally, the fixed film tube is rolled up by the coiling and receiving system. The continuous continuous process has simple equipment, easy operation and low investment cost. 6 1273024 [Solid mode] The manufacturing method and apparatus of the present invention are further described in more detail below according to the preferred embodiment shown in the accompanying drawings: As shown in the first figure, the present invention The blown film forming manufacturing method and device for the plastic (PS) plastic shrink film tube comprises: an extrusion blown film forming system, an extension drawing device 2, a shaping processing system device 3, and a winding and receiving system device 4 The blown film forming system 1 is provided with an inlet funnel 11, an extruding mechanism 12, a circular extrusion die 13 and a circular air-cooling cooling device 14. • The extension drawing device 2 is provided with a heating device 18 and hot water. The box 21 and the circular shaped water tank mold 22. The shaping treatment system 3 is provided with a hot gas circulation device 28. The winding and receiving system 4 is provided with a reel 31. The above-mentioned extrusion blown film forming system device 1, the extension and extraction system Device 2 and The type of processing device 3 is provided with guiding plate sets 16, 24, 29 and speed control pressing bows | wheel sets 17, 19, 25, 26, 30. The manufacturing method of the invention is to put the polystyrene styrene plastic material into the blow. The feeding funnel 11 of the film forming system 1 is inserted into the extruding mechanism 12 * The extruding mechanism 12 is provided with a self-heating temperature uniform control device, which can heat the polystyrene plastic material (about 1801 C - 230 °) C is melted, and the snail is squeezed out, and is formed into a cylindrical rubber tube by rounding out the die 13, and then air is supplied to the die hose, and then @ is cooled by the circular air-cooling type cooling device 14. The blown film raw tube 15 formed into a D1 size is introduced into the hot water tank 21 of the extension drawing system 2 via the guide platen group 16 and the quick-pressing and pressing wheel set 17 and then folded into a flat shape to be heated. 18 is heated, the heating device 18 is provided with a temperature-controlled device of uniform temperature, and the blown film original tube 8 1273024 15 is inserted into the hot water tank 21 and then pulled by the speed-controlled pressure guiding wheel set 19, at this time, the blown film original tube 1 5 is continuously heated to gradually form a softened film tube 20, and the soft b-film tube 20 is passed through a round shape. Sink module 22, and then through the guide 24 and the platen set wheel speed control pressure lead 25 drawn to a given type of processing system which will be installed 3. In this process, since the blown film tube 15 has been softened by the heat of the hot water tank 21 (about 80oC -100oC), the blown film tube 15 is filled after the air pressure is applied to the blown film tube 15. There will be a balloon-like expansion. Further, since the cooling device of the cooling water channel is provided in the circular shaped water tank mold 22, when the blown film original tube 15 φ expands to contact with the circular shaped water tank mold 22, the expansion The film tube is cooled to fix the dimension D2, and the expanded film tube size D2 and the original blown film tube 15 size D1艮P are laterally extended. Furthermore, when the softening film tube 20M is driven by the front and rear speed control pressing wheel sets 19 and 25, the quick-pressing pressure guiding wheel set 25 is designed to draw the stretch softening film tube 20, that is, the front and rear sections. The difference in speed between the sets of wheels 19 and 25 stretches and softens the film tube 20, resulting in a straight extension effect, so that the softened film tube 20 is formed as an extended film tube 23, which is guided by the platen group 24 and The quick-pressing pressure guide wheel set 25 is folded into a flat shape and introduced into the shaping and processing system. 3. The speed-controlled pressure guide wheel set 2 (3 passes through the hot gas circulation device 28, and is formed into a D3 shaped film tube after contact with hot air. 27» is again guided by the guide plate set 29 and the quick-control pressure guide set 30, and is taken up for storage by the take-up reel 31 of the take-up and take-up system. The hot gas temperature of the hot gas circulation device 28 is on the cell example. The adjustment is set between the softening point of the plastic to the normal temperature (about 45 °C-653⁄4), so that the cooled extension film tube 23 is filled with air pressure in the tube and is expanded into a round shape film tube. At the time, since the temperature of 8 1273024 does not reach the plastic softening point, no expansion and expansion will occur. Since the film tube is slowly reduced and adjusted during the moderate heating process, it is formed into the aforementioned shaped hose 27, which is stable and stable, and is not easily affected by environmental and temperature changes. In summary, the present invention is a polystyrene (PS) plastic material used as a raw material, and is first formed into a blown film original tube by an extrusion mechanism of a blown film forming system, and then extended to draw a sputum device. Formed into an extended film tube, and finally formed into a shaped film tube by a stereotyped processing device, the device is easy to install and has a small footprint, low investment cost, and economic benefit, which not only improves The utility model has the advantages of work efficiency, low production cost, and is suitable for the shrinkage film tube made of general thermoplastic plastic, and the manufacturing method and the manufacturing device thereof are unprecedentedly known as an invention having novelty and industrial use value. Samples have been made* and tested to prove that they are of good quality. Please check one sample and one test report. Please refer to the review.
