Description

Technical Field

[0001] The present invention relates to the field of plastic film processing, and specifically relates to a production method and processing equipment for a high-performance film. Background Art

[0002] The share of plastic packaging and plastic packaging products in the market is increasing. Especially for composite plastic flexible packaging, it has been widely used in the fields of food, medicine, chemical industry, etc. Among them, food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, cooked food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] In response to this, our company has developed a high-performance film. Such a high-performance film is composed of five layers of auxiliary films, and one strand of it can achieve the effect of two strands of ordinary plastic films on the market. However, due to the differences in the properties and materials of the film embryos of each part that make up such a high-performance film, the existing plastic film processing equipment on the market cannot meet the production requirements. In response to this situation, our company has designed a high-performance film processing equipment. This equipment can adapt to the processing of various film embryos, can adjust different types of film embryos, and can also be used for the forming of auxiliary films to improve processing efficiency. Summary of the Invention

Detailed implementation manners

[0035] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] Refer to Figures 1 to 8 , a production method of a high-performance film, comprising the following steps:

[0037] S1: The high-performance film is composed of five auxiliary films. The material of the first layer can refer to the existing materials on the market, such as plastic 2436H; while the materials of the second layer and the third layer are the same, and the specific ratio is: a mixture of plastic 7042 and plastic 2010, wherein the range of plastic 7042 is 60%-80%, specifically 70%, and the range of plastic 2010 is 20%-40%, specifically 30%; the material of the fourth layer is a mixture of plastic 7042 and recycled material, wherein the proportion of plastic 7042 is 90%, and the recycled material is 10%-30%; the material of the fifth layer is the same as that of the first layer, and can also refer to the existing materials on the market;

[0038] S2: The operator processes the materials of the five auxiliary films into embryos in batches. In this process, the operator first pours the plastic raw material particles into the device, and then the device runs to plasticize and melt the plastic particles. After the raw materials are extruded, the molten plastic raw materials will extend in a sheet shape and be cooled and shaped. Finally, the extrusion parameters of the device are adjusted to make it a qualified auxiliary film embryo, and finally a film embryo of five auxiliary films is formed;

[0039] S3: Finally, the operator adjusts the extrusion parameters in this device to extrude and form the film embryo of the five-layer auxiliary film. The finally formed plastic film is the high-performance film required this time, and the thickness of one filament of this high-performance film can achieve the effect of two filaments of ordinary plastic films on the market.

[0040] A processing device for high-performance films, comprising:

[0041] A blanking mechanism 1, connected to the robotic arm, capable of plasticizing, melting and extruding plastic raw materials;

[0042] A first adjustable extrusion mechanism 4, arranged below the blanking mechanism 1, including a shaping roller shaft 13, the position of which can be finely adjusted to be suitable for processing film embryos of different materials and thicknesses;

[0043] A second adjustable extrusion mechanism 23, arranged below the first adjustable extrusion mechanism 4, including a first extrusion roller shaft 31 and a second extrusion roller shaft 37. The first extrusion roller shaft 31 is arranged above the second extrusion roller shaft 37, and the distance between the first extrusion roller shaft 31 and the second extrusion roller shaft 37 can be adjusted to further extrude film embryos of different thicknesses;

[0044] A cooling mechanism 46, including an air pump 51, which can provide the cold air flow required for cooling.

[0045] The blanking mechanism 1 includes a storage barrel 2 and a melting material dropping box 3. The melting material dropping box 3 is fixedly connected to the output end of the robotic arm, and the storage barrel 2 is fixedly arranged vertically above the melting material dropping box 3. When shaping the film embryo, the operator pours the plastic raw materials into the storage barrel 2, and then the melting material dropping box 3 will plasticize and melt the plastic raw materials. Finally, the robotic arm drives the melting material dropping box 3 to move, and the melted plastic raw materials will drip downwards.

[0046] The first adjustable extrusion mechanism 4 further includes a first conveyor belt 5, two first driving rollers 6, two second driving rollers 7, two first support frames 9, two first belts 8, two second support frames 10 and two third support frames 11. The first conveyor belt 5 is horizontally arranged below the melting material dropping box 3. The two ends of the first conveyor belt 5 are connected by roller transmission. The two first driving rollers 6 are respectively fixedly arranged at the two ends of the roller close to the melting material dropping box 3. The two second driving rollers 7 are respectively fixedly arranged at the two ends of the roller far from the melting material dropping box 3. The two first belts 8, one end of each is respectively in transmission connection with the two first driving rollers 6, and the other end of each is respectively in transmission connection with the two second driving rollers 7. The two first support frames 9 are respectively arranged beside the two first driving rollers 6 and are rotationally connected with the two first driving rollers 6 through pins. The two second support frames 10 are respectively arranged beside the two second driving rollers 7 and are rotationally connected with the two second driving rollers 7 through pins. The two third support frames 11 are respectively arranged on one side of the two second support frames 10 away from the two first support frames 9. During the operation of the device, the second driving rollers 7 will rotate. The specific reason for rotation will be explained later. The two second driving rollers 7 drive the two first driving rollers 6 to rotate through the two first belts 8, that is, the two rollers will rotate. Since the two ends of the first conveyor belt 5 are respectively in transmission connection with the two rollers, the first conveyor belt 5 will move at this time. The plastic raw materials dripping from the melting material dropping box 3 will fall on the upper end of the first conveyor belt 5 and move along with the first conveyor belt 5. During this process, the first support frames 9, the second support frames 10 and the third support frames 11 all play a supporting role.

[0047] The first adjustable extrusion mechanism 4 further includes two first worm wheels 12, two second worm wheels 14, two fixed supports 15 and two movable supports 17. The two fixed supports 15 are respectively fixedly connected with the two third support frames 11. Limiting chutes 16 are formed on both of the two fixed supports 15. The two first worm wheels 12 are respectively coaxially fixed to the two second driving rollers 7. The two movable supports 17 are respectively arranged at the two ends of the shaping roller shaft 13. The lower ends of the two movable supports 17 are respectively slidably connected with the corresponding limiting chutes 16. The two second worm wheels 14 are respectively arranged on one side of the two movable supports 17 away from the shaping roller shaft 13. The two second worm wheels 14 are fixedly connected with the shaping roller shaft 13 through rollers. This roller shaft is rotationally connected with the two movable supports 17. When it is necessary to control the thickness of the film blank, the operator can adjust the position of the shaping roller shaft 13. The specific adjustment method will be explained later. At this time, when the shaping roller shaft 13 rotates, its side wall will be pressed against the first conveyor belt 5. The plastic raw materials transported by the first conveyor belt 5 will be preliminarily extruded and formed by the shaping roller shaft 13. And as the shaping roller shaft 13 rotates, the preliminarily formed film blank will be pulled and move downward, and finally the secondary forming of the film blank will be realized.

[0048] The first adjustable extrusion mechanism 4 further includes two adjusting lead screws 19, four fixed rod seats 18, two turntables 20, two driving motors 21 and two double-headed worms 22. One ends of the two adjusting lead screws 19 are respectively rotatably connected to the two moving supports 17, and the other ends are threadedly connected to the groove walls of the limit sliding grooves 16. The two turntables 20 are respectively fixedly axially connected to the ends of the two adjusting lead screws 19 away from the moving supports 17. The two double-headed worms 22 are respectively arranged beside the two moving supports 17. One ends of the two double-headed worms 22 are in transmission connection with the two first worm wheels 12, and the other ends are in transmission connection with the two second worm wheels 14. The four fixed rod seats 18 are respectively arranged at the two ends of the two double-headed worms 22 and are rotatably connected thereto. The driving motor 21 is arranged on the side of the double-headed worm 22 away from the first transmission belt 5, and the output end of the driving motor 21 is connected to the double-headed worm 22 through a coupling. When the device is running, the driving motor 21 starts and drives the double-headed worm 22 to rotate, and the double-headed worm 22 drives the first worm wheel 12 and the second worm wheel 14 in transmission connection therewith to rotate. At this time, the first worm wheel 12 drives the second driving roller 7 to rotate, and the second worm wheel 14 drives the shaping roller shaft 13 to rotate. And because the rotation directions of the first worm wheel 12 and the second worm wheel 14 are opposite, as can be seen from the previous text, the rotation direction of the shaping roller shaft 13 is opposite to that of the first transmission belt 5. At this time, the operator can rotate the turntable 20 for adjustment according to the thickness of the film blank required for this processing, that is, the turntable 20 drives the adjusting lead screw 19 to rotate. Since the adjusting lead screw 19 is rotatably connected to the moving support 17 and the adjusting lead screw 19 is also threadedly connected to the groove wall of the limit sliding groove 16, the adjusting lead screw 19 drives the moving support 17 to move along the limit sliding groove 16, and the moving support 17 is connected to the shaping roller shaft 13 through a roller, that is, the movement of the shaping roller shaft 13 is completed.

[0049] The second adjustable extrusion mechanism 23 further includes two power bevel gears 24, two driven bevel gears 25, two driving gears 26, two first moving gears 27, two first driving gears 28, two first linkage rods 29 and two first cylinders 30. The two power bevel gears 24 are respectively fixedly and axially connected to the ends of the two bidirectional worm gears 22 away from the driving motor 21. The two driven bevel gears 25 are respectively arranged beside the two power bevel gears 24 and meshed with them. The two driving gears 26 are respectively coaxially arranged with the two driven bevel gears 25. The two driving gears 26 are both fixedly connected to the two driven bevel gears 25 through the same roller shaft. This roller shaft is connected to the fixed support 15 through a shaft seat. The two first moving gears 27 are respectively arranged beside the two driving gears 26 and meshed with them. The two first driving gears 28 are respectively fixedly connected to the two ends of the first extrusion roller shaft 31. The two first driving gears 28 are respectively meshed with the two first moving gears 27. The two first cylinders 30 are fixedly arranged beside the two first driving gears 28. One ends of the two first linkage rods 29 are respectively hinged to the output ends of the two first cylinders 30, and the other ends are respectively rotatably connected to the roller shaft at the two driving gears 26. The two first driving gears 28 and the two first moving gears 27 are both rotatably connected to the two first linkage rods 29 through pins. When the film blank is subjected to secondary extrusion molding, the bidirectional worm gear 22 will drive the power bevel gear 24 axially connected to it to rotate, and the power bevel gear 24 will drive the driven bevel gear 25 meshed with it to rotate. The driven bevel gear 25 will drive the driving gear 26 coaxially connected to it to rotate. The driving gear 26 will drive the first moving gear 27 meshed with it to rotate. The first moving gear 27 will drive the first driving gear 28 meshed with it to rotate. The rotation of the two first driving gears 28 will drive the first extrusion roller shaft 31 fixedly connected to them to rotate. During this process, the first cylinder 30 can be adjusted according to the thickness of the processed film blank. As the first cylinder 30 operates, the first linkage rod 29 will move, and accordingly, the position of the first extrusion roller shaft 31 will be changed.

[0050] The second adjustable extrusion mechanism 23 further includes a linkage long shaft 40, two second moving gears 32, two second linkage rods 33, two reversing gears 34, two third linkage rods 35, two second driving gears 36, two fourth linkage rods 38 and two second cylinders 39. The two second moving gears 32 are respectively arranged beside the two first driving gears 28 and meshed with them. The two reversing gears 34 are respectively arranged beside the two second moving gears 32 and meshed with them. The two second driving gears 36 are coaxially and fixedly connected to both ends of the second extrusion roller shaft 37 respectively. The two second driving gears 36 are respectively meshed with the two reversing gears 34. The two second linkage rods 33, one end of which is rotatably connected to the two first linkage rods 29 through a pin, the middle end is rotatably connected to the second moving gear 32 through a pin, and the other end is rotatably connected to the two reversing gears 34 through a pin. The two third linkage rods 35, one end of which is rotatably connected to the reversing gear 34 and the second linkage rod 33 through a pin at the same time, and the other end is rotatably connected to the second driving gear 36 through a pin. The two second cylinders 39 are fixedly arranged beside the two second driving gears 36. The linkage long shaft 40 is arranged on one side of the second extrusion roller shaft 37 close to the third support frame 11. Both ends of the linkage long shaft 40 are fixedly connected to the third support frame 11 through shaft seats. One end of each of the two fourth linkage rods 38 is hinged to one of the two second cylinders 39 respectively, and the other end is hinged to the linkage long shaft 40 respectively. As the position of the first extrusion roller shaft 31 changes, the position of the second extrusion roller shaft 37 should also change. At this time, the second cylinder 39 is started, and the fourth linkage rod 38 will move along with the output end of the second cylinder 39 and finally drive the second extrusion roller shaft 37 connected to it to displace. During this process, the third linkage rod 35 and the second linkage rod 33 can ensure that the second extrusion roller shaft 37 can still rotate after changing its position. As can be seen from the foregoing, the rotation of the first driving gear 28 will drive the second moving gear 32 meshed with it to rotate, the rotation of the second moving gear 32 will drive the reversing gear 34 meshed with it to rotate, and the rotation of the reversing gear 34 will drive the second driving gear 36 meshed with it to rotate. Generally speaking, at this time, the rotation directions of the first extrusion roller shaft 31 and the second extrusion roller shaft 37 are opposite, and the preliminarily processed film embryo can be subjected to shaping processing through the extrusion of the first extrusion roller shaft 31 and the second extrusion roller shaft 37.

[0051] The second adjustable extrusion mechanism 23 further includes a second transmission belt 41, a power motor 45, two third driving rollers 42, two fourth driving rollers 43 and two second belts 44. The second transmission belt 41 is arranged obliquely between two second cylinders 39. The two ends of the second transmission belt 41 are connected by two rollers in a transmission manner. The two third driving rollers 42 are fixedly axially connected to the two ends of the roller located above, and the two third driving rollers 42 are fixedly axially connected to the two ends of the roller located below. For the two second belts 44, one end thereof is in transmission connection with the two third driving rollers 42, and the other end is in transmission connection with the two fourth driving rollers 43. The output end of the power motor 45 is fixedly axially connected to one of the fourth driving rollers 43. When the device is running: the film blank after secondary extrusion molding will fall onto the second transmission belt 41. At this time, the power motor 45 starts and drives the fourth driving roller 43 connected thereto to rotate. Since the two fourth driving rollers 43 are connected by a roller, they will start to rotate simultaneously at this time. At the same time, the two fourth driving rollers 43 can drive the two third driving rollers 42 to rotate through the two second belts 44, and finally drive the transmission belt to rotate through the roller.

[0052] The cooling mechanism 46 further includes two cooling plates 47 and an air delivery pipe 50. An air delivery hole 49 is formed on the side wall of the cooling plate 47, and a plurality of air permeation holes 48 are formed on both sides of the cooling plate 47. For the two cooling plates 47, one is fixedly arranged inside the first transmission belt 5, and the other is arranged inside the second transmission belt 41. The air delivery pipe 50 is arranged at the upper end of the air pump 51. One end of the air delivery pipe 50 is connected to the air pump 51, and the other end is respectively connected to the air delivery holes 49 of the two cooling plates 47. When the device is running: since the plastic film needs to be cooled during molding, the air pump 51 starts and inputs the cooling air flow into the cooling plate 47 through the air delivery pipe 50. After the cooling air flow is input from the air delivery hole 49, it is output from a plurality of air permeation holes 48. At this time, the belt surfaces of the first transmission belt 5 and the second transmission belt 41 arranged outside the two cooling plates 47 will be cooled. As can be seen from the foregoing, the film blanks of the plastic film are transported through the first transmission belt 5 and the second transmission belt 41 during processing and molding. At this time, the film blanks can be cooled by the cooled belt surfaces.

[0053] Working principle: When this device is in operation, it can be known that the high-performance film produced by this device has a five-layer composition structure, which are respectively: The material of the first layer can refer to the existing materials on the market, such as plastic 2436H; while the materials of the second layer and the third layer are the same, and their specific ratios are: a mixture of plastic 7042 and plastic 2010, where the range of plastic 7042 is 60%-80%, specifically 70%, and the range of plastic 2010 is 20%-40%, specifically 30%; the material of the fourth layer is a mixture of plastic 7042 and recycled material, where plastic 7042 accounts for 90%, and the recycled material is 10%-30%; the material of the fifth layer is the same as that of the first layer, and it can also refer to the existing materials on the market. Therefore, when this device processes and manufactures plastic films, three groups of film blanks should be processed in batches, and finally the film blanks should be covered in sequence and then extruded again to form the final high-performance film.

[0054] Subsequently, the operator starts the robotic arm and other power sources of this device, and pours the plastic raw materials into the storage barrel 2. The melting material dropping box 3 will plasticize and melt the plastic raw materials, and then the robotic arm drives the melting material dropping box 3 to move, and the melted plastic raw materials will drip downwards. First, the air pump 51 will provide a continuous cooling air flow and cool the first conveyor belt 5 and the second conveyor belt 41, which is convenient for the plastic raw materials after melting and dripping to cool and form during the transportation process.

[0055] Since the thicknesses of the three groups of initial film blanks and the high-performance film blank after final forming are all different, and the extrusion forces required for the film blanks are also different, during the product processing, the operator should fine-tune the turntable 20 according to the product specifications being processed, so that the shaping roller shaft 13 is close to the second driving roller 7. When the unprocessed film blank passes through the shaping roller shaft 13, the shaping roller shaft 13 is squeezed against the first conveyor belt 5 to preliminarily shape the film blank, and the preliminarily shaped film blank is pulled between the first extrusion roller shaft 31 and the second extrusion roller shaft 37.

[0056] When the preliminarily shaped film blank passes through the first extrusion roller shaft 31 and the second extrusion roller shaft 37, the operator can adjust the first cylinder 30 and the second cylinder 39 to change the distance between the first extrusion roller shaft 31 and the second extrusion roller shaft 37, so that the preliminarily shaped film blank is subjected to secondary shaping processing to ensure that film blanks of different models and materials can all be processed by adjustable means.

[0057] Finally, when the three groups of initial film blanks are processed and formed, the operator repeats the shaping process in the way of stacking five layers. The finally formed plastic film is the high-performance film required this time. The thickness of one strand of this high-performance film can achieve the effect of two strands of ordinary plastic films on the market.

[0058] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
