Description

Technical Field

[0001] This invention relates to the field of thin film processing equipment, and in particular to a thin film processing production line.

[0002] This invention relates to the field of thin film processing methods, and in particular to a continuous, automated thin film processing production method. Background Technology

[0003] In the continuous processing of thin film materials, the final product is a continuous, repetitive product unit. For example, a plastic glove film for pipe cleaning consists of two continuous, semi-open layers of film with welded components such as gloves. Each product unit is semi-closed at both ends, and discontinuous lines are provided at the closed edges of two units to facilitate segmentation or adjustment of the unit's position along its length. Manufacturing this product requires processes such as punching, welding, inspection, and cross-sealing / cross-cutting. The raw material for making the product is film rolls, which need to be unwound; subsequent product processing requires rewinding and packaging.

[0004] Because the film material is continuous along its length, intermittent feeding is required during processes such as punching, welding, inspection, and cross-cutting, depending on the process time. During the periods when feeding is stopped, a stationary section of film material is processed.

[0005] Existing technologies include methods that use multiple workstations for manual operation of each step in the processing of irregularly shaped films. This method disperses each workstation and has to be completed manually, resulting in low production efficiency, long delivery time, high equipment idleness, high labor costs, and poor product quality.

[0006] Existing technologies for continuous processing employ synchronous motion motor drives. The motors in the working section must maintain linear speed synchronization with those in the unwinding and rewinding sections. However, since the rotational speeds of the unwinding and rewinding motors are related to the roll size, real-time synchronization often results in the film being either too tight or too loose. High synchronization of the final linear speeds of the conveyor motors in the rewinding, processing, and unwinding sections is required, necessitating high control precision. When multiple processes are completed within the same stop-conveyor time, and the operating plane is long, the difficulty of synchronous control increases, easily leading to large variations in tension in the processing section, or a loose tension affecting processing positioning, or a tight tension tearing the film material.

[0007] The existing technology suffers from several technical problems. Firstly, the processing of irregularly shaped thin film products lacks automation and a continuous, assembly-line production method. This results in inconsistent product quality control, low production efficiency, long lead times, and high processing costs. Secondly, the limited flexibility of existing dedicated production lines is also a significant technical issue. Summary of the Invention

Moreover, the modular design of the system increases system flexibility. In actual production, production efficiency can reach more than ten times that of manual production, and product quality is also improved by one level.

[0080] Compared with the prior art, the present invention provides a film processing production method that continuously and repeatedly processes film products in a film processing production line. The film processing production line system is divided into an unwinding system, a processing system, and a winding system. The movement characteristic of the unwinding system is that the diameter of the film roll decreases as processing progresses, requiring adjustment of the unwinding speed. The unwinding system includes a first film self-tensioning device and an unwinding machine, which is driven by a first drive mechanism. The processing system needs to complete punching and welding operations during a period of film stillness. The film in the processing system is driven by a second traction device, which is driven by a second drive mechanism. The movement of the second drive mechanism is intermittent. The first drive mechanism is also continuously driven during the film stillness period of the second drive mechanism. The movement characteristic of the winding system is that the diameter of the film roll gradually increases as processing progresses. When the required outer diameter for packaging is reached, the winding process needs to be paused and replaced with a new roll. During the winding process, the unwinding speed needs to be adjusted. The unwinding system includes a second film self-tensioning device and a winding machine, which is driven by a third drive mechanism. The third drive mechanism is also continuously driven during the film stillness period of the second drive mechanism. Therefore, the aforementioned continuous production method can ensure that the film is stationary during processing while the unwinding and winding are continuous and controllable according to its own motion characteristics, thereby improving the degree of mechanization and automation from raw materials to finished product packaging, increasing production efficiency, and improving product precision.

[0168] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0169] See Figure 1 and Figure 2 As shown, in order to achieve the above objectives, the present invention provides a thin film processing production line, comprising:

[0170] Unwinding system A includes an unwinder 11 and a first film self-tensioning device 12. The unwinder 11 includes a first drive mechanism 111 for driving the film roll 112 to release the film to be processed 2.

[0171] Processing system B includes a film punching device 3, a film welding device 4, and a second traction device 5. The second traction device 5 is driven by a second drive mechanism 501, which moves intermittently. The second drive mechanism 501 can be a motor, while the second traction device 5 includes a film conveying mechanism consisting of a drive roller, a driven roller, and a pressing mechanism. The drive roller is driven by a motor, which moves intermittently.

[0172] The first film self-tensioning device 12 is used to tension the film 2 between the unwinding system A and the processing system B.

[0173] The winding system C includes a winding machine 6 and a second film self-tensioning device 7. The winding machine 6 includes a third drive mechanism 64 for driving the film 2 product to be wound up, and the second film self-tensioning device 7 is used to tension the film between the processing system B and the winding system C.

[0174] The unwinding machine 11 includes a film roll mounting base 113, on which a film roll 112 is mounted. The film roll 112 rotates around its own axis to release the film 2. The first drive mechanism 111 includes a first motor 114 and a magnetic powder brake 115. The magnetic powder brake 115 is controlled by a magnetic powder tension controller 116. The output shaft of the first motor 114 is equipped with the magnetic powder brake 115 and is connected to the rotation shaft of the film roll 112 through a gear transmission mechanism 117. The alignment unit 118 includes an alignment instrument used to measure the alignment status of the film material in the width direction. The film roll mounting base 113 is mounted on a guide rail 119 parallel to the width direction for alignment of the film material in the width direction.

[0175] Accordingly, the production line provided by the present invention can perform continuous film processing. When punching, welding and other processing operations are performed in processing system B, they can be carried out on a stationary film processing plane, and the film plane has tension. Moreover, it can be cleverly made so that when the film in processing system B is stationary, the unwinding system A and the winding system C can continuously and uniformly release the film and wind up the finished film.

[0176] The first film self-tensioning device 12 includes a counterweight roller 121 and a rotating shaft 122. The counterweight roller 121 can be driven by the rotating shaft 122 to rotate around the axis of the rotating shaft. The film 2 partially covers the counterweight roller 121 from below. A first film conveying device 123 is provided at the process front end of the first film self-tensioning device 12. The first film conveying device 123 includes a first driving roller 124, a first conveying mechanism 125, a first passive roller 126, and a first pressing mechanism 127. The first driving roller 124 and the first passive roller 126 clamp the film 2 above the first film self-tensioning device 12. The first conveying mechanism 125 is driven by a first conveying motor. Accordingly, tension is provided by gravity, and the up-and-down movement can automatically coordinate the inconsistencies in the film conveying length between the processing system B and the unwinding system A and the rewinding system C at each moment.

[0177] The film punching device 3 and the film welding device 4 are mounted on the same working frame 31 and share the same stacking inclined block 32. Accordingly, the stacking inclined block 32 can serve as a positioning reference for the processing system B in the width direction. The gap between the apex of the stacking inclined block 32 and the corresponding line and the outer edge of the film material, particularly the fold line of a double-layered folded film material, is measured using the correction unit 118. Furthermore, since the film punching device 3 and the film welding device 4 are mounted on the same working frame 31, their relative positions in the length direction can be guaranteed to have a certain level of accuracy.

[0178] The thin film punching device 3 includes a punching die 33 and a punching cutter 34. The punching die 33 is provided with a groove 331. The shape of the punching cutter 34 fits into the shape of the groove 331. The groove 331 is positioned directly above and below the punching cutter 34. The thin film 2 layer to be punched is located between the punching die 33 and the punching cutter 34. The punching cutter 34 is driven by a punching cylinder 35 to press against the film and the groove. The punching cylinder 35 is controlled by a first solenoid valve.

[0179] The thin film welding device 4 is located in the downstream section of the thin film punching device 3.

[0180] The thin film welding device 4 includes a welding mold platform 41, which is mounted on a welding mold guide rail 42 for moving below the two layers of the film to be processed, parallel to the working plane, perpendicular to the length of the film, and parallel to the width of the film. The welding mold platform 41 is driven by a welding mold platform cylinder 43, which is controlled by a second solenoid valve. The welding mold platform 41 includes a welding mold mounting hole 411. The thin film welding device 4 includes a welding mold 44, which has a positioning part 441 and a positioning hole 412 in the welding mold mounting hole 411. The positioning part 441 and the positioning hole 412 are fitted together. Welding components are fitted onto the welding mold 44. The mold mounting hole 411 also includes an upper hole, the diameter of which is larger than the diameter of the positioning hole, forming a stepped hole. The upper part of the welding mold 44 includes a welding component fitting part. The welding mold 44 is stepped and tubular, and the diameter of the welding component fitting part is smaller than the diameter of the upper hole, forming a gap. With the subsequent cooling air blowing, the welded parts can be blown away from the welding mold 44.

[0181] The thin film welding apparatus 4 includes a welding head 45, which is driven by a welding head drive cylinder 451 to move towards the welding component on the welding mold 44. The welding head 45 has a heating device, and the welding head drive cylinder 451 is controlled by a third solenoid valve. Accordingly, the welding head 45 presses against the thin film 2, the welding component, and the welding mold 44, and the welding head 45 is heated by the heating device, melting and welding the thin film and the welding component together.

[0182] The thin-film welding apparatus 4 includes a cooling mechanism 46, which comprises an air-cooling pipe 461, compressed gas 462, a baffle 463, and a baffle driving cylinder 464. The air-cooling pipe 461 is controlled by a fourth solenoid valve, and the baffle driving cylinder 464 is controlled by a fifth solenoid valve. Accordingly, the opening of the air-cooling pipe 461 is located below the welding mold mounting hole 411, and the welding mold 44 is a hollow tubular shape. The welding component is fitted inside the welding mold 44. When the air-cooling pipe 461 is opened, compressed air blows towards the welding component, blowing the welding component away from the welding mold 44. At this time, the welding head 45 still has a certain temperature. To prevent the welding component from being blown onto the welding head 45, a baffle 463 is set between the welding head 45 and the welding component. When the welding head 45 moves back to its original position, the baffle 463 prevents the welding component from touching the welding head 45.

[0183] A thin film sealing and cross-cutting device 8 is provided in the downstream section of the thin film welding device 4. The thin film sealing and cross-cutting device 8 includes:

[0184] The sealing and welding cross-cutting lower mold 81 has a shape that includes a rectangle and a trapezoid. The connection between the rectangle and the trapezoid is rounded, and the acute angle of the trapezoid is rounded. The rectangular part of the upper plane of the sealing and welding cross-cutting lower mold 81 is provided with rectangular cross-cutting grooves arranged at intervals.

[0185] A sealing and welding transverse cutting upper mold 82 is provided, corresponding to a sealing and welding transverse oblique lower mold 81. The sealing and welding transverse cutting upper mold 82 includes a main pressure plate, which comprises a rectangle and a trapezoid. The acute angle of the trapezoid is cut off by a parallel straight line parallel to the axis of the trapezoid. The rectangular portion of the lower plane of the main pressure plate is provided with spaced rectangular transverse cutting blades. The main pressure plate has a heater. The sealing and welding transverse cutting upper mold 82 is driven by a sealing and welding transverse cutting cylinder, which is controlled by a sixth solenoid valve. The sealing and welding transverse cutting lower mold 81 and the sealing and welding transverse cutting upper mold 82 are arranged in pairs, allowing discontinuous dividing lines to be cut at corresponding positions of the transverse cutting blades and transverse cutting grooves. This ensures product continuity while easily dividing it into product units. The other rectangular portions of the main pressure plate are heated by the heater, enabling the welding of wide-width closed ends between adjacent product units. Furthermore, by setting the positions of the transverse cutting blades and transverse cutting grooves on the rectangular portions, typically along the axis of the rectangle, the relative positions of the dividing lines and the welding surfaces of the closed ends can be well controlled. However, welding in the width direction must ensure its position in the width direction.

[0186] The film pressing mechanism 83 includes a pressing roller and a pressing plate. Located outside the main pressing plate, the pressing mechanism presses the film material against the sealing and welding transverse cutting die. The pressing mechanism 83 can be driven by the main pressing plate or move independently. This forms a stable transverse cutting and welding operating surface for the film 2.

[0187] The cooling system 84 includes cooling pipes, coolant, a cooling pump, and a heat sink. The cooling pipes surround the heat sink, and the die for sealing and welding is placed on the heat sink. The cooling pump is driven by a cooling pump motor. After the sealing and welding work is completed, the cooling system 84 performs a refrigeration cycle to cool and solidify the sealed film.

[0188] An inspection platform 85 is provided between the film welding device 4 and the film sealing and cross-cutting device 8. The inspection platform 85 includes at least two rollers 851 and 852 for supporting the film material. The operator inspects the welded components and film material in the plane between the rollers 851 and 852 to ensure that they are firmly welded, that the welded components are not damaged, and tidies up the welded components. If it is a double-layer film material, the welded components are tucked between the two layers of film material.

[0189] The winding system C also includes a folding device 9, which includes a triangular pyramid 91. The triangular pyramid has a first edge 911, a first triangular face 912 with the first edge as its side, a first vertex 913 in addition to the two endpoints of the first edge, a second edge 914 in addition to the two edges of the first triangular face, and the other two edges of the first triangular face are a third edge 915 and a fourth edge 916. The film 2 is laid on the first edge 911 and covers the first triangular face 912. The film 2 covers the third edge 915, the fourth edge 916 and the first vertex 913, forming a fold line at the first vertex 913. The film 2 wraps around the second edge 914 and outputs as a folded film 2.

[0190] Two shaping guide rollers 921 and 922 are provided directly opposite the second ridge 914.

[0191] A transition roller 93 is provided at the first ridge 911.

[0192] An exhaust mechanism 94 is provided between the winding machine 6 and the folding device 9. The exhaust mechanism 94 includes an exhaust drive roller 941, which is driven to rotate by an exhaust drive mechanism; an exhaust drive roller 942, which includes a rotating shaft 943 and a pressure ring 944; the pressure ring 944 is sleeved on the rotating shaft 943, and there are at least two pressure rings 944 arranged with gaps between them; and an exhaust pressing mechanism 945, which presses the exhaust drive roller 942 against the exhaust drive roller 941 to press the folded film 2 between the pressure ring 944 and the exhaust drive roller 941. Accordingly, the air in the folded film product is exhausted to the gap, slowly pressing the folded film 2, instead of exhausting the gas to the front of the process, which would affect the folding effect.

[0193] The second film self-tensioning device 7 includes a counterweight roller 71 and a rotating shaft 72. The counterweight roller 71 can be driven to rotate around the axis of the rotating shaft 72, and the film 2 partially covers the counterweight roller 71 from below. Accordingly, the film 2 is tensioned under the gravity of the counterweight roller 71, and the length change of the film 2 in this section due to asynchrony can be absorbed by the up-and-down movement of the counterweight roller 71.

[0194] The winding machine 6 includes a coreless winding mechanism 61, which comprises a first coil 611 and a second coil 612 facing each other. The first coil 611 and the second coil 612 clamp the folded film 2, and a third drive mechanism drives the first coil 611. The coreless winding mechanism 61 includes a force sensor 613, which is connected to the second coil 612 to measure the winding force. The force sensor 613 is connected to the frequency converter module of the third drive mechanism. The motor speed is adjusted according to the winding force measured by the force sensor 613. When the tightening force increases, the tightening speed is slowed down. Moreover, as the winding increases, the circumferential linear velocity of the roll edge increases at the same rotation speed, which also reflects the increase in winding force. The winding speed can also be controlled by measuring the rotation angle of the rotating shaft 72.

[0195] The thin film processing production line also includes:

[0196] Product unit counter 62 records the number of processed product units. It is connected to the production line control system and also electrically connects to an alarm. Therefore, when the number of product units on each roll reaches the required packaging size (currently set at 25 units per package), the alarm alerts the production line to change rolls.

[0197] Cutting blade 63 is used to cut product units that are connected front and rear rolls.

[0198] To achieve the above objectives, the present invention provides a method for thin film processing and production.

[0199] In a film processing production line, the film products of the continuously repeating product unit are divided into an unwinding system A, a processing system B, and a rewinding system C.

[0200] The motion characteristic of the unwinding system A is that the diameter of the film roll decreases as the processing progresses, requiring adjustment of the unwinding speed. The unwinding system A includes a first film self-tensioning device 12 and an unwinder 11, which is driven by a first drive mechanism.

[0201] Processing system B needs to complete punching and welding within a period of film stillness. The film of processing system B is driven by a second traction device, which is driven by a second drive mechanism. The movement of the second drive mechanism is intermittent.

[0202] The first drive mechanism also drives continuously during the time when the diaphragm of the second drive mechanism is stationary.

[0203] The motion characteristic of the winding system C is that the diameter of the film roll gradually increases as the processing progresses. When the outer diameter of the packaging is required, it is necessary to pause and replace the new roll. During the winding process, the unwinding speed needs to be adjusted. The unwinding system includes a second film self-tensioning device and a winding machine, and the winding machine is driven by a third drive mechanism.

[0204] The third drive mechanism also drives continuously during the time when the thin film of the second drive mechanism is stationary.

[0205] The thin film processing production method mainly involves providing a set of controllable electrical components and controlling these electrical components to form a complete control system D. The following electrical components are set between the unwinding system A, the processing system B, and the winding system C.

[0206] Unwinding system A:

[0207] The unwinding machine is driven by a first motor D01, and a first control device D21 controls the unwinding speed of the first motor D01; the unwinding first conveyor mechanism includes a second motor D02, which is controlled by a second control device D22.

[0208] The unwinding system A is equipped with an angle measuring sensor D41 for the first film self-tensioning device. The angle measuring sensor D41 measures the rotation angle of the counterweight roller in the first film self-tensioning device to adjust the rotation speed of the first control device D21 and the second control device D22.

[0209] The second control device D22 and the first control device D21 are matched for control.

[0210] The main function of the unwinding system A is to control the film conveying speed. The magnetic powder brake can solve the speed matching problem by sensing the tension of the unwinder.

[0211] Processing System B:

[0212] The first conveyor mechanism is processed, comprising:

[0213] The third motor D03 is controlled by the third control device D23;

[0214] Thin film punching apparatus, comprising:

[0215] The first cylinder pushes the punching tool. The first cylinder is controlled by the first solenoid valve D61, which is controlled by the fourth control device D24.

[0216] The punching process is as follows: the punching tool completes the punching action by reciprocating once.

[0217] Thin film welding apparatus, comprising:

[0218] The second cylinder pushes the welding mold platform. The second cylinder is controlled by the second solenoid valve D62, which is controlled by the fifth control device D25.

[0219] The third cylinder pushes the welding head. The third cylinder is controlled by the third solenoid valve D63, which is controlled by the sixth control device D26.

[0220] The first gas cooling pipe blows compressed air toward the welded parts. The first gas cooling pipe is controlled by the fourth solenoid valve D64, which is controlled by the seventh control device D27.

[0221] The fourth cylinder pushes the baffle. The fourth cylinder is controlled by the fifth solenoid valve D65, which is controlled by the eighth control device D28.

[0222] The fifth control device D25 controls the second cylinder to push the welding mold platform to the welding position; the sixth control device D26 controls the third cylinder to push the welding head to the welding position and then withdraw it from the welding position; the eighth control device D28 controls the fourth cylinder to push the baffle to extend; the seventh control device D27 controls the compressed air to blow out for a period of time and then shuts it off; the eighth control device D28 controls the fourth cylinder to drive the baffle back to its original position; the fifth control device D25 controls the second cylinder to drive the welding mold platform out of the welding position to the mold placement position.

[0223] The welding process is as follows: In the working sequence of the thin film welding device, the welding component is placed onto the welding mold by a person or a robot, and an instruction is given to the fifth control device D25, which can be measured by sensors or manually operated buttons. At this time, the welding mold platform is pushed under the welding head by the second cylinder, which is the welding position. Subsequently, the automatic sequence completes the following steps in sequence: the welding head presses against the welding mold, the welding head retracts from the welding mold, the baffle extends to block between the welding head and the welding mold, compressed air used for cooling and blowing the welding component away from the welding mold is blown out, and the welding mold platform returns to the welding component placement position, starting the cycle of the next thin film welding process. Because of the action of placing the welding component onto the welding mold, the thin film welding work becomes the control process for the entire static period of the thin film.

[0224] The second conveying mechanism includes:

[0225] The fourth motor, D04, is controlled by the ninth control device, D29.

[0226] Thin-film sealing and cross-cutting apparatus, comprising:

[0227] The fifth cylinder pushes the main pressure plate. The fifth cylinder is controlled by the sixth solenoid valve D66, which is controlled by the tenth control device D30.

[0228] The sixth cylinder pushes the pressure film mechanism. The sixth cylinder is controlled by the seventh solenoid valve D67, which is controlled by the eleventh control device D31.

[0229] The first cooling system, the cooling pump of the first cooling system is driven by the fifth motor D05, and the fifth motor D05 is controlled by the twelfth control device D32;

[0230] The eleventh control device D31 controls the film pressing mechanism to press against the film. The tenth control device D30 pushes the main pressure plate to perform a sealing and welding cross-cutting action and then retracts. The twelfth control device D32 turns on the fifth motor D05 for cooling and then stops. The eleventh control device controls the film pressing mechanism D31 to reset.

[0231] The sealing and cross-cutting process is as follows: after the film pressing mechanism flattens the film, the main pressing plate presses down to complete the sealing and cross-cutting work. The main pressing plate retracts, the cooling system is turned on to cool and solidify the sealing and cross-cutting parts, and then the process stops. The film pressing mechanism retracts.

[0232] The third conveying mechanism includes:

[0233] The sixth motor, D06, is controlled by the thirteenth control device, D33.

[0234] In processing system B, during a period of inactivity, different workstations complete the work of one product unit, including punching, welding, sealing and cross-cutting, and inspection. Among these processes, welding and inspection involve operator participation. A reasonable inactivity period enables streamlined operations.

[0235] Rewinding System C:

[0236] The first winding conveyor mechanism includes:

[0237] The seventh motor, D07, drives the exhaust mechanism and is controlled by the fourteenth control device, D34.

[0238] The third drive mechanism of the winding machine is driven by the eighth motor D08, which is controlled by the fifteenth control device D35.

[0239] The fourteenth control device D34 and the fifteenth control device D35 are matched for control. The fifteenth control device D35 adjusts the speed of the eighth motor D08 according to the rotation angle of the counterweight roller of the second film self-tensioning device. The fifteenth control device D35 is adjusted by measuring the rotation angle of the counterweight roller in the second film self-tensioning device through the second deflection angle measuring sensor D42.

[0240] The fifteenth control device controls the start and stop of the entire production line. Accordingly, when the diameter after winding reaches the packaging requirements or the number of product units reaches the packaging requirements, the front and rear rolls need to be cut, and then the rear roll needs to be rewound. At this point, production can be stopped to perform a roll changeover.

[0241] The fifth control device is controlled by the welding mold placement process. Accordingly, in processing system B, the manually operated control process is defined as the welding process, and the manually operated welding mold placement work involves placing the welding parts into the welding mold and into the mold placement hole.

[0242] The third, ninth, and thirteenth control devices synchronously control the corresponding motors, intermittently switching them on or off for synchronized movement. These three control devices are redundant thin-film drive units installed on long production lines.

[0243] During the time period when the corresponding motors are stopped by the third, ninth, and thirteenth control devices, the fourth, fifth, sixth, seventh, eighth, tenth, eleventh, and twelfth control devices control the operation of related components.

[0244] The film linear speed of the unwinding system A should also match the film winding linear speed of the winding system C. The second control device D22 controls the motor speed to convert it into the circumferential linear speed of the drive roller, which needs to be matched with the fourteenth control device D34's conversion of the motor speed into the circumferential linear speed of the drive roller.

[0245] Compared with existing technologies, this invention provides a film processing production line, comprising: an unwinding system including an unwinding machine and a first film self-tensioning device, the unwinding machine including a first drive mechanism for driving the film roll to release the film to be processed; a processing system including a film punching device, a film welding device, and a second traction device, the second traction device being driven by a second drive mechanism, the second drive mechanism moving intermittently; the first film self-tensioning device for tensioning the film between the unwinding system and the processing system; and a winding system including a winding machine and a second film self-tensioning device, the winding machine including a third drive mechanism for driving the film product to wind up, the second film self-tensioning device for tensioning the film between the processing system and the winding system. Accordingly, through the assembly line design, the automation of processing irregularly shaped, multi-position film welding components can be improved, while ensuring processing accuracy. Moreover, the modular design of the system increases system flexibility. In actual production, production efficiency can reach more than ten times that of manual production, and product quality is also improved by one level.

[0246] Compared with the prior art, the present invention provides a film processing production method that continuously and repeatedly processes film products in a film processing production line. The film processing production line system is divided into an unwinding system, a processing system, and a winding system. The movement characteristic of the unwinding system is that the diameter of the film roll decreases as processing progresses, requiring adjustment of the unwinding speed. The unwinding system includes a first film self-tensioning device and an unwinding machine, which is driven by a first drive mechanism. The processing system needs to complete punching and welding operations during a period of film stillness. The film in the processing system is driven by a second traction device, which is driven by a second drive mechanism. The movement of the second drive mechanism is intermittent. The first drive mechanism is also continuously driven during the film stillness period of the second drive mechanism. The movement characteristic of the winding system is that the diameter of the film roll gradually increases as processing progresses. When the required outer diameter for packaging is reached, the winding process needs to be paused and replaced with a new roll. During the winding process, the unwinding speed needs to be adjusted. The unwinding system includes a second film self-tensioning device and a winding machine, which is driven by a third drive mechanism. The third drive mechanism is also continuously driven during the film stillness period of the second drive mechanism. Therefore, the aforementioned continuous production method can ensure that the film is stationary during processing while the unwinding and winding are continuous and controllable according to its own motion characteristics, thereby improving the degree of mechanization and automation from raw materials to finished product packaging, increasing production efficiency, and improving product precision.
