Description

Technical Field

[0001] This invention belongs to the field of polymer materials technology, and in particular relates to a hybrid molding module system and preparation method for composite film packaging materials. Background Technology

[0002] With the continuous upgrading of the consumer market and the increasing global awareness of environmental protection, the modern packaging industry is facing unprecedented challenges and opportunities. Traditional single-material plastic films, due to their limited or insufficient barrier properties, mechanical strength, preservation function, or sustainability, are no longer able to meet the complex needs of high-end fields such as food, pharmaceuticals, and electronics for packaging materials that are multifunctional, lightweight, have long shelf life, and are environmentally friendly.

[0003] Chinese patent CN106863736A discloses an apparatus and method for producing TPU composite film, comprising: a screw extruder; the screw extruder includes a screw barrel and a drive device connected to the screw; the number of screw extruders is greater than or equal to 2; a distributor; the distributor is provided with a flow channel, the inlet of the flow channel being connected to the outlet of the screw extruder; and a T-die; the T-die is connected to the outlet of the flow channel.

[0004] As shown above, this device can adjust the thickness, number of layers, and proportion of each component of the composite film by adjusting the discharge flow rate ratio of each screw extruder, thereby meeting the production needs of functionally adjustable TPU composite films. Furthermore, the equipment described in this invention is low-cost, highly operable, suitable for mass production of composite products, and can reduce losses to below 0.5%, improving production efficiency and automation. However, the heat generated during the extrusion of materials by the screw extruder cannot be utilized. Current technology generally uses gas exchangers to recover and utilize this heat, but traditional gas exchangers have low capacity utilization efficiency. Waste hot air needs to be heated by a metal plate to heat fresh air, resulting in a heat transfer temperature difference. Simultaneously, due to oil buildup, oil condenses and deposits carbon on the heat exchange plate, forming an increasingly thick insulation layer, continuously increasing thermal resistance and causing performance degradation over time. Moreover, the cost of subsequent maintenance is high, requiring shutdown for maintenance. Summary of the Invention

[0009] Preferably, the disassembly assembly includes a housing fixedly connected to the top of the fixed housing, four sliding shafts slidably connected to the inner wall of the housing, wedges fixedly connected to the bottom of the four sliding shafts, first springs fixedly connected to the top of the four wedges, the tops of the four first springs fixedly connected to the inner wall of the housing, the four sliding shafts respectively located inside the four first springs, and connecting frames fixedly connected to the tops of the four sliding shafts.

[0010] Preferably, a frame is fixedly connected to the bottom of the fixed housing, a telescopic rod is fixedly connected to the inner wall of the frame, a fixed frame is fixedly connected to the outer wall of the telescopic rod, the outer wall of the fixed frame is slidably connected to the inner wall of the frame, a second spring is fixedly connected to the side of the fixed frame near the telescopic rod, the end of the second spring away from the fixed frame is fixedly connected to the inner wall of the frame, the telescopic rod is located inside the second spring, and a bidirectional lead screw is rotatably connected to the inner wall of the fixed frame.

[0011] Preferably, the inner wall of the bidirectional lead screw is threaded with two second clamping plates, the inner walls of the two second clamping plates are engaged with the outer wall of the limiting block, the outer walls of the four inclined blocks are engaged with the inner wall of the first clamping plate, and the inner wall of the fixed housing is fixedly connected to a second duct fan through a pipe, the output end of the second duct fan being fixedly connected to the inner wall of the right side partition of the fixed housing through a pipe.

[0014] This invention also discloses a method for preparing a composite film packaging material, specifically including the following steps: S1. The second duct fan delivers the hot air, which has been treated by the pretreatment mechanism, to the right side of the interior of the fixed housing. Then, the sprayer is activated by the external controller to spray the right side of the interior of the fixed housing. S2. These water mists will carry away the fine oil and dust contained in the hot air. After purification, the hot air is drawn by the first pipe fan through the third pipe and input into the gas distributor. Then it is transported to the silo through four distribution pipes to dry the material. S3. Water mist containing oil and dust will accumulate in the area at the bottom right side of the fixed housing. At this time, the first water pump will draw this water mist through the first pipe and send it into the purifier for purification. Then, it will be transported back to the sprayer through the second water pump and the second pipe for recycling.

[0015] Preferably, the spray flow rate of the sprayer in S3 needs to be precisely controlled by an external controller to prevent the flow rate from being too high or too low, which would result in the oil stains in the hot air not being completely removed or the hot air losing too much heat.

[0016] The present invention has the following beneficial effects: 1. This hybrid molding module system and preparation method for composite film packaging materials adopts a technical route of direct deep purification and reuse of high-temperature process waste gas generated during the hybrid molding process. It fundamentally abandons the traditional indirect heat recovery mode that relies on gas-to-gas plate heat exchangers, eliminates the inherent heat loss caused by the temperature difference between the two sides of the heat exchange plate, and realizes near-direct utilization of heat energy. Secondly, since the complex structure and narrow flow channel of the heat exchange core are eliminated, the overall air resistance of the system is greatly reduced, and the fan power required to drive the airflow is reduced accordingly, avoiding the paradox that the energy-saving benefits of the traditional system are offset by its own high energy consumption. Furthermore, it fundamentally solves the problem of reverse performance degradation caused by the condensation of oil on the plate surface, carbon accumulation and the formation of insulating scale layer in traditional heat exchangers, ensuring a long-term reliable return on energy-saving investment.

[0017] 2. The hybrid molding module system and preparation method for composite film packaging materials include an independent pretreatment mechanism located before the spray purification unit of the cleaning mechanism. This mechanism performs the first physical interception and coarse filtration on the high-temperature exhaust gas extracted from the hybrid molding mechanism, effectively removing most of the solid dust particles and some condensed liquid oil droplets. On the one hand, it prevents a large number of pollutants from directly entering the subsequent spray wet treatment unit, avoiding the problem of pollutants accumulating in the droplets and causing rapid deterioration of the circulating water quality and excessive treatment load. On the other hand, by removing large particulate impurities from these high-temperature exhaust gases in advance, it ensures the stability and accuracy of the subsequent spray temperature control process, making it possible to achieve high-precision closed-loop control of the exhaust gas outlet temperature by controlling the spray volume, thereby providing high-quality hot air with constant temperature and cleanliness for the downstream drying process.

[0018] 3. The hybrid molding module system and preparation method for composite film packaging materials, through the design of disassembly components, makes the daily inspection, cleaning or replacement maintenance of the core filter elements of the pretreatment mechanism, such as ceramic fiber boards, extremely simple and efficient. Maintenance personnel can complete the disassembly and assembly in a short time without special tools or complicated operations, which shortens the downtime required for system maintenance and reduces the labor costs of long-term operation and maintenance.

[0019] 4. The mixing molding module system and preparation method for composite film packaging materials realizes the heat conduction path from the inside of the material to the outside by embedding the heating plate into the mixing screw, shortens the heat conduction distance, improves the heating response speed and heat energy utilization efficiency, and at the same time reduces the temperature of the outer wall of the mixing shell, reducing heat loss to the environment. It also makes the material more uniformly heated during the melting process, effectively preventing local overheating degradation or poor plasticization.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] See Figures 1-11 This invention discloses a hybrid molding module system for composite film packaging materials and provides the following three technical solutions: The first implementation includes a hopper 1, with a detachable vent cover 101 on the top of the hopper 1. The vent cover 101 is equipped with high-efficiency filter cotton, which is used to prevent external dust from contaminating the raw materials in the hopper while allowing air to pass through. A cleaning mechanism 2 is provided on the outer wall of the hopper 1, and a mixing and molding mechanism 4 is provided on the back of the hopper 1. A molding mechanism 5 is provided on the back of the mixing and molding mechanism 4. The cleaning mechanism 2 includes a fixed housing 201 fixedly connected to the outer wall of the hopper 1. The right side of the fixed housing 201 forms a sealed cavity, isolating the cleaning flow path from the external environment. A first pipe 202 is fixedly connected to the inner wall of the fixed housing 201. One end of the first pipe 202 extends into the interior of the fixed housing 201, and the other end of the first pipe 202 away from the fixed housing 201 is fixedly connected to a first water pump 203. The first water pump 203 provides the power required for the circulation of the cleaning medium. The output end of the first water pump 203 is fixedly connected to a purifier 204 through a pipe. The purifier 204 is equipped with a multi-stage filtration unit to remove grease and dust washed off from the inner wall of the hopper by the cleaning medium, maintaining the cleanliness of the medium. The output end of 204 is fixedly connected to a second water pump 205 via a pipe. The second water pump 205 is used to pump the purified cleaning medium into the sprayer 207. The output end of the second water pump 205 is fixedly connected to a second pipe 206, which serves as the output channel for the cleaning medium. The outer wall of the second pipe 206 is fixedly connected to the inner wall of the fixed housing 201. The end of the second pipe 206 away from the second water pump 205 is fixedly connected to the sprayer 207. The spray from the sprayer 207 is preferably a cone-shaped mist to achieve efficient coverage cleaning. A pretreatment mechanism 3 is provided inside the fixed housing 201. The pretreatment mechanism 3 is located on the left side of the fixed housing 201, outside the cleaning flow path, and is used to pretreat the air entering the hopper 1. The silo 1 is equipped with a conveying mechanism, which uses multiple conveying screws to transport the material inside the silo 1 to the mixing shell 405. All the conveying screws are electrically connected to an external power source.

[0026] A third pipe 208 is fixedly connected to the inner wall of the fixed housing 201. The third pipe 208 serves as an airflow channel, with its inlet connected to the internal partition of the fixed housing 201, for conveying the purified hot air to the silo 1. A first pipe fan 209 is fixedly connected to the bottom of the third pipe 208, for generating directional airflow and driving the air to flow in the pretreatment flow path. A fourth pipe 210 is fixedly connected to the output end of the first pipe fan 209. The fourth pipe 210 is used to convey the pretreated air to the distribution unit. A gas distributor 211 is fixedly connected to the outer wall of channel 210. The gas distributor 211 has a pressure equalization chamber inside to ensure that the airflow is evenly distributed to the four distribution pipes 212. The gas distributor 211 is located at the bottom of the silo 1. This arrangement allows the pre-treated gas to penetrate the raw material layer in the silo 1 from bottom to top. Four distribution pipes 212 are fixedly connected to the top of the gas distributor 211. The distribution pipes 212 are made of corrosion-resistant material and have micropores at the top to promote uniform gas diffusion. The tops of the four distribution pipes 212 are fixedly connected to the bottom of the silo 1.

[0027] The second embodiment differs from the first embodiment in that the pretreatment mechanism 3 includes a sealing plate 301 that contacts the outer wall of the fixed housing 201. A high-temperature resistant sealing gasket is provided between the sealing plate 301 and the fixed housing 201 to ensure airtightness at the connection. Several ceramic fiber plates 302 are fixedly connected to the outer wall of the sealing plate 301. The ceramic fiber plates 302 serve as the core heat insulation and filtration medium, and have a uniform microporous structure inside, which can efficiently block heat conduction while allowing gas to pass through and initially intercepting dust. Several ceramic fiber plates 302 are connected to the fixed housing. The inner wall of the sealing plate 301 is inserted, which facilitates the orientation and positioning of the ceramic fiber board 302. The outer wall of the sealing plate 301 is fixedly connected to the first clamping plate 303, which serves as the upper locking and fastening component and has a groove. The outer wall of the sealing plate 301 is fixedly connected to the limiting block 304, which serves as the lower positioning and locking component and whose shape matches the inner contour of the second clamping plate 315. The fixed housing 201 is provided with a disassembly assembly, which is used to realize the overall quick assembly and disassembly of the pretreatment mechanism 3, which facilitates the replacement or maintenance of the ceramic fiber board 302.

[0028] The disassembly assembly includes a housing 305 fixedly connected to the top of the fixed housing 201. The housing 305 forms the mounting base and guide cavity of the upper locking mechanism. Four sliding shafts 306 are slidably connected to the inner wall of the housing 305. An inclined block 307 is fixedly connected to the bottom of each of the four sliding shafts 306. The inclined surface of the inclined block 307 engages with the corresponding surface of the first clamping plate 303, enabling the vertical movement of the sliding shafts 306 to be converted into a horizontal clamping force or release on the first clamping plate 303. A first spring 308 is fixedly connected to the top of each of the four inclined blocks 307, providing a downward tendency for the inclined blocks 307 to move. The elastic preload force drives the inclined block 307 to clamp the first clamping plate 303 under normal conditions, achieving automatic locking. The tops of the four first springs 308 are fixedly connected to the inner wall of the housing 305. The four sliding shafts 306 are located inside the four first springs 308 respectively. This layout ensures that the spring force acts directly on the sliding shafts 306 and maintains their motion alignment. The tops of the four sliding shafts 306 are fixedly connected to the connecting frame 309. By operating the connecting frame 309 to move upward, the elastic force of the first springs 308 can be overcome, and all sliding shafts 306 and inclined blocks 307 can be lifted simultaneously, thereby releasing the locking of the first clamping plate 303.

[0029] A frame 310 is fixedly connected to the bottom of the fixed housing 201. The frame 310 forms the installation and housing space for the lower locking mechanism. A telescopic rod 311 is fixedly connected to the inner wall of the frame 310. A fixed frame 312 is fixedly connected to the outer wall of the telescopic rod 311. The outer wall of the fixed frame 312 is slidably connected to the inner wall of the frame 310. A second spring 313 is fixedly connected to the side of the fixed frame 312 near the telescopic rod 311. The second spring 313 is a return spring. When the telescopic rod 311 retracts, it provides an elastic force to reset the fixed frame 312. The end of the second spring 313 away from the fixed frame 312 is fixedly connected to the inner wall of the frame 310. The telescopic rod 311 is located inside the second spring 313. A bidirectional lead screw 314 is rotatably connected to the inner wall of the fixed frame 312.

[0030] Two second clamping plates 315 are threadedly connected to the inner wall of the bidirectional screw 314. The inner sides of the two second clamping plates 315 form a groove that matches the shape of the limiting block 304. The rotation of the bidirectional screw 314 drives the second clamping plates 315 to move closer or further away. The inner walls of the two second clamping plates 315 are engaged with the outer wall of the limiting block 304. When the groove is closed, the second clamping plates 315 hold the limiting block 304 tightly, thus firmly fixing the lower part of the pretreatment mechanism 3. When the groove is open, the constraint on the limiting block 304 is released, and the outer walls of the four inclined blocks 307 are engaged with the inner wall of the first clamping plate 303. The inner wall of the fixed housing 201 is fixedly connected to the second duct fan 316 through a pipe. The second duct fan 316 is used to provide the gas distributor 211 with clean airflow that has been filtered and conditioned by the pretreatment mechanism 3. The output end of the second duct fan 316 is fixedly connected to the inner wall of the right side partition of the fixed housing 201 through a pipe.

[0031] The third embodiment differs from the first two in that the mixing and molding mechanism 4 includes a base 401 fixedly connected to the outer wall of the gas distributor 211. The base 401 is a rigid frame structure, providing a stable mounting foundation for the mixing unit. A motor 402 is fixedly connected to the top of the base 401. The motor 402 is preferably a variable frequency speed control motor, so as to precisely control the speed of the mixing screw 404 according to process requirements. A coupling 403 is fixedly connected to the outer wall of the output shaft of the motor 402. The coupling 403 is used to transmit torque and compensate for minor misalignments. The coupling 403 has a fixed connection to the inner wall of a mixing screw 404. The screw thread of the mixing screw 404 is specially designed so that its pitch and groove depth can be varied along the axial direction to achieve the functions of conveying, compressing, shearing and homogenizing materials. The base 401 has a fixed connection to the outer wall of a mixing shell 405. The outer wall of the mixing screw 404 is rotatably connected to the inner wall of the mixing shell 405. The outer wall of the mixing shell 405 is connected to an insulation plate 406 by screws. The insulation plate 406 tightly wraps around the outside of the mixing shell 405 to reduce heat loss during the mixing process. The mixing screw 404 has a heating rod inside, which heats from the inside out. The heat is directly conducted through the metal, which is much more efficient than conducting from the outer wall to the inside. The heat exchange area is much larger than the contact area of ​​several external heating coils, which can shorten the preheating time.

[0032] Two third-pipe fans 407 are fixedly connected to the inner wall of the insulation board 406 via pipes. The third-pipe fans 407 are used to extract hot air or volatile gases that may accumulate in the insulation interlayer of the mixing shell 405. The output ends of the two third-pipe fans 407 are fixedly connected to a fifth pipe 408 via pipes. The fifth pipe 408 serves as a gas recovery channel. The top of the fifth pipe 408 is fixedly connected to the inner wall of the fixed shell 201, thereby introducing the extracted gas into the space of the fixed shell 201 where the pretreatment mechanism 3 is located for unified treatment or reuse. A heating rod is installed inside the mixing screw 404 for heating the material. The forming mechanism 5 includes an extruder 501 fixedly connected to the outer wall of the mixing shell 405 via a conveying pipe. A screen changer and a melt pump can be installed in the conveying pipe for filtering impurities and stabilizing the melt pressure and flow rate. A roller 502 is rotatably connected to the outer wall of the extruder 501. The roller 502 constitutes a preliminary forming and cooling unit for the extruded melt.

[0033] This invention also discloses a method for preparing a composite film packaging material, specifically including the following steps: The material silo 1 stores materials. When composite film production is required, the raw materials are conveyed to the mixing shell 405 via the conveying mechanism inside the silo 1. Then, the motor 402 is started by the external controller, and the motor 402 drives the mixing screw 404 to rotate via the coupling 403, conveying and extruding the material. The material is then conveyed to the extruder 501 through a pipeline for extrusion. After extrusion, the material is cooled by the roller 502 before subsequent winding. The mixing screw 404 is equipped with a heating rod to heat the material. During the conveying and extrusion process, the mixing screw 404 also generates heat. This heat is absorbed by the insulation plate 406 to maximize the insulation of the mixing screw 404. However, some excess heat is still lost. The third pipeline fan 407 is started by the external controller to convey this excess heat through the pipeline to the fifth pipeline 408, and then input into the fixed shell 201. The second pipeline fan 316 is then started by the external controller to absorb and convey this heat from above. In this process, the heat... The gas passes through multiple ceramic fiber panels 302, which absorb most of the oil and dust in the hot air. After being transported out by the second duct fan 316, the internal gas content has been pre-treated. Then, it is transported to the right side of the fixed housing 201. Next, the first duct fan 209 is activated via an external controller to absorb and transport the gas from the right side of the fixed housing 201. During this process, the sprayer 207 continuously sprays fine mist to carry away any remaining oil and dust in the gas. After the mist carries away the oil and dust, it settles on the fixed housing. The material accumulates in the bottom right area of ​​body 201 and is then extracted by the first water pump 203 through the first pipe 202 and transported to the purifier 204 for purification. After purification, it is transported back to the sprayer 207 by the second water pump 205 through the second pipe 206 for spraying. The first pipe fan 209 transports the purified spray to the gas distributor 211, and then the gas distributor 211 transports the purified hot air to the inside of the silo 1 through four distribution pipes 212 for drying the material particles.

[0034] After prolonged use, the ceramic fiber plate 302 needs to be removed for cleaning. To do this, simply move the connecting frame 309 upwards, causing the four sliding shafts 306 to move upwards and compressing the first spring 308, thereby moving the inclined block 307. Then, manually rotate the bidirectional lead screw 314, causing the two second locking plates 315 to move away from each other. At this point, the second locking plates 315 release their restriction on the limiting block 304, and the second spring 313 rebounds, moving the fixed frame 312 and the internal bidirectional lead screw 314 and second locking plates 315. The sealing plate 301 can then be removed, along with the ceramic fiber plate 302, for cleaning. After cleaning, simply insert the sealing plate 301 and ceramic fiber plate 302 back into the fixed housing 201. During insertion, the first locking plate 303 will be inserted into the housing 305. The contact surface between the inclined block 307 and the first clamping plate 303 is inclined. Therefore, during the insertion process, the inclined block 307 will be pressed upward, thereby compressing the first spring 308 and driving the sliding shaft 306 to move upward. After installation, the first spring 308 rebounds and presses the inclined block 307, so that the inclined block 307 is inserted into the first clamping plate 303, limiting the first clamping plate 303. Then, the fixing frame 312 is pulled outward, so that the second spring 313 and the telescopic rod 311 are stretched. When the limiting block 304 is between the two second clamping plates 315, the bidirectional screw 314 is rotated in the opposite direction, causing the two second clamping plates 315 to interact with each other, so that they limit the limiting block 304. Meanwhile, the second spring 313 continues to pull the fixing frame 312, so that the second clamping plates 315 will also continue to pull the limiting block 304, enhancing the sealing effect.
