Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of thin film thermal lamination, and particularly to a heat treatment thin film positioning laminating machine. Background Art
[0002] The existing laminating machine for food-grade thin film lamination is a device specifically designed for laminating two or more layers of food-grade thin films. Its purpose is to manufacture composite thin films with various functions (such as barrier properties, freshness preservation, etc.) to meet the needs of related industries such as food packaging.
[0003] However, the existing devices still have the following defects in specific use: 1. During the thermal compounding process, when the thin film passes between two hot rollers, it is heated, and the surrounding air is also heated to become hot air. According to the principle of thermodynamics, the density of hot air is smaller than that of cold air, and upward convective motion will occur. For the thin film, due to the upward dispersion of hot air, the exchange rate of hot air on the upper surface of the thin film with the surrounding cold air will be faster than that on the lower surface. This is because the hot air on the upper surface is more easily displaced by the surrounding cold air, resulting in a relatively faster heat dissipation rate on the upper surface. On the other hand, the hot air on the lower surface is hindered by the upward movement of the hot air on the upper surface and has a relatively smaller contact area with the surrounding cold air. Since the lower surface is close to equipment components such as hot rollers and the space is relatively enclosed, the heat dissipation is relatively slow. This temperature difference between the upper and lower surfaces will affect the compounding quality of the thin film, causing inconsistent shrinkage rates of the thin film during subsequent processing or use.
[0004] 2. Since both the heating compounding and the cooling treatment adopt the round roller method and the interval distance is close, during the specific operation of the equipment, heat is easily transferred between the two. For example, when the thin film after heating compounding is transferred to the cooling area, part of the heat will be dissipated into the space near the cooling area, increasing the temperature of the cooling area. This not only reduces the efficiency of the cooling treatment but also consumes more cooling resources of the equipment to achieve the desired cooling effect. Conversely, the low temperature of the cooling area will also affect the temperature stability of the heating compounding area. The low temperature of the cooling area will slightly reduce the temperature of the heating compounding area near it, affecting the compounding quality of the thin film, such as incomplete curing of the glue or uneven bonding force between the compound layers.
[0005] 3. During the thermal lamination and cooling processes inside the equipment, there will be some hot air and cold air. Dust and impurities in the air are in a suspended state. When the hot air generated by thermal lamination and the cold air generated by cooling continuously disperse, these dust and impurities will be drawn into the air current and then move randomly with the air current. Moreover, during the thermal lamination and cooling processes of the film, due to factors such as friction and temperature changes, static electricity will be generated. Static electricity has the property of attracting light and small objects. Dust and impurities belong to light and small objects. When there are dust and impurities carried by the air current around the film with static electricity, these dust and impurities are more likely to be adsorbed onto the film surface. If the dust and impurities adhere to the film surface, it will damage the integrity of the film, form tiny channels, making it easier for oxygen, water vapor, etc. to penetrate through the film, thereby reducing the barrier performance of the film.
[0006] Therefore, in view of this, the present invention proposes a heat treatment film positioning laminating machine to make up for and improve the deficiencies of the existing technology. Summary of the Invention
[0007] To solve the above technical problems, the present invention provides a heat treatment film positioning laminating machine to solve the technical problems raised in the above background technology.
[0008] To achieve the above purposes, the technical solution adopted by the present invention is: a heat treatment film positioning laminating machine for thermally laminating a film body, including a base frame. A first unwind assembly is installed at the bottom left of the base frame. A winding roller is installed on the right side of the first unwind assembly. A second unwind assembly is installed at the bottom right of the base frame. A coating module is installed on the right side of the second unwind assembly. A thermal lamination module is installed above the first unwind assembly. A cooling module is installed on the right side of the thermal lamination module. A gradual transition mechanism is arranged between the thermal lamination module and the cooling module. A winding pretreatment mechanism is arranged above the gradual transition mechanism. The gradual transition mechanism is used to perform temperature compensation on the film body after thermal lamination, and the winding pretreatment mechanism is used to perform pretreatment on the film body before winding.
[0009] Further, the gradual transition mechanism includes a balance chamber fixedly connected to the side wall of the base frame. The film body is slidably connected to the inside of the balance chamber. A pair of top plates is installed on both sides of the balance chamber. Guide plates are symmetrically and fixedly connected to the inside of the balance chamber. A turbine shaft is rotatably connected to the inside of the balance chamber.
[0010] Further, the pair of top plates includes two curved arc plates, and the two curved arc plates are respectively fixedly connected to the upper left vertex and the lower right vertex of the balance chamber. Through grooves are respectively formed at the connection positions of the pair of top plates and the balance chamber.
[0011] Further, the curved arc plate of the pair of top plates close to the thermal compounding module is gradually bent upward, and the curved arc plate of the pair of top plates close to the cooling module is gradually bent downward.
[0012] Further, the guide plate is installed in an inclined manner along the tangent direction of the left through groove, and the guide plates are symmetrically distributed with respect to the turbine shaft.
[0013] Further, the winding pretreatment mechanism includes a storage cylinder installed above the balance bin. A convex plate shaft is rotatably connected inside the storage cylinder. Elastic gasket rods are evenly and slidably connected inside the storage cylinder. The lower ends of the elastic gasket rods are slidably connected with spray nozzles, and curved through pipes are symmetrically installed inside the spray nozzles.
[0014] Further, a rectangular convex plate is fixedly connected to the outer wall of the convex plate shaft, and curved plates are evenly fixedly connected above the elastic gasket rods. The curved plates in the elastic gasket rods are located on the moving path of the rectangular convex plate in the convex plate shaft.
[0015] Further, antistatic spray is stored inside the storage cylinder, and both ends of the curved through pipe are respectively in communication with the storage cylinder and the spray nozzle.
[0016] Further, the elastic gasket rods are located at the position directly below the storage cylinder, and the elastic gasket rods inside the spray nozzles are initially located above the curved through pipes.
[0017] Further, the thermal compounding module mainly includes a pressure sensor, a tension roller, and heating rollers symmetrically distributed up and down. The turbine shaft is in transmission connection with the heating rollers in the thermal compounding module through a belt, and the convex plate shaft is in transmission connection with the tension roller in the cooling module through a belt.
[0018] Further, the cooling module mainly includes a temperature sensor, a water pump, and a cooling roller. The cooling roller in the cooling module and the heating roller in the thermal compounding module are on the same horizontal plane.
[0019] Further, the gluing module mainly includes a glue tank container for storing an adhesive and a coating roller matching the diameters and lengths of the heating roller and the cooling roller.
[0020] Compared with the prior art, the beneficial effects of the present invention are: (1) In order to improve the temperature difference during the film transmission process, the device guides the air flow through an additional balancing chamber. A turbine shaft is arranged inside the balancing chamber, which rotates continuously during the operation of the equipment, thereby forming a negative pressure environment in the chamber. This negative pressure environment can absorb the hot air generated in the thermal composite area and the cold air released in the cooling area through the carefully designed grooves at the top and bottom corners of the balancing chamber. According to the opening positions of the grooves on the left and right sides of the balancing chamber and the rotation direction of the turbine shaft, the hot air is sucked in from the top and guided to flow downward, closely fitting the upper surface of the film. At the same time, the cold air is sucked in from the bottom and guided to flow upward, fitting the lower surface of the film. In this way, the temperatures of the upper and lower surfaces of the film are compensated and adjusted, so that the film reaches a nearly uniform temperature before entering the cooling process, thereby achieving a uniform distribution of the film temperature. This improvement not only significantly improves the accuracy and stability of film composite, but also helps to reduce the problem of inconsistent film shrinkage caused by temperature differences, thereby improving the overall quality and performance of the film.
[0021] What is particularly important is that during the operation of the equipment, additional gas energy will be generated. The position and shape design of the curved arc plate in the top plate group can cleverly utilize the natural characteristics of hot air going up and cold air going down, and conduct secondary utilization of the gas energy that was originally wasted. Specifically, the hot air in the thermal composite area is guided to the conveying step before thermal composite to preheat the film, which helps to maintain the physical properties of the film stable and prevent the film from shrinking or deforming due to sudden temperature changes. At the same time, the cold air in the cooling area is guided to the equipment component operation area for cooling, which can effectively maintain the equipment components within a suitable operating temperature range and reduce the probability of component failure due to excessive temperature, thereby improving the operating reliability of the entire equipment. In addition, since this method does not require an additional drive source to guide the flow of hot and cold air, it directly reduces the energy consumption cost of the equipment, enabling it to save a lot of energy expenses for the enterprise in long-term operation.
[0022] Among them, the top of the balancing bin is farther away from the film than the bottom. The device installs the guide plate at an angle along the tangent direction of the left through slot, so that the hot air entering the balancing bin from the left through slot can change its flow direction along the inclined direction of the guide plate, and can be orderly guided to a specific direction, so that it can flow more accurately to the surface area of the film where the temperature needs to be adjusted, and when the airflow interacts with the guide plate, the inclination angle and symmetrical distribution of the guide plate can reasonably adjust the momentum components of the airflow in the horizontal and vertical directions, thereby avoiding turbulence after the airflow enters the balancing bin.
[0023] Compared with the existing treatment methods, the temperature gradient transition zone brought by the balance chamber introduced in this device also has the following advantages: First: By effectively compensating for the temperature difference between the upper and lower surfaces of the film, the physical properties of the film during the lamination process become more uniform, ensuring that the adhesive can cure under uniform temperature conditions, thereby improving the adhesion between the adhesive and the film surface, ensuring the uniformity of the physical properties of the film and reducing the occurrence of delamination.
[0024] Second: Through the additionally added temperature gradient transition area, the film undergoes a temperature buffering process. During this process, the temperature change occurs gradually, reducing the generation of thermal stress. Moreover, since the film is adjusted in a relatively mild temperature change environment, the temperatures of the upper and lower surfaces and different regions of the film can decrease more uniformly, making the shrinkage rate more consistent.
[0025] Third: By adding a balance chamber, the heat transfer between the heating and lamination area and the cooling area is effectively isolated, reducing the need for additional heat supplementation in the heating and lamination area. And it offsets the heat transferred from the heating and lamination area for the cooling equipment, thereby reducing this unnecessary energy consumption.
[0026] (2) To improve the surface quality of the film after thermal lamination, the device continuously rotates the convex plate shaft, causing the nozzle to intermittently output antistatic spray into the balance chamber. From the perspective of electrostatics principles, the antistatic spray can neutralize the static electricity generated on the film surface during the processing and generate an antistatic layer on the film surface, thereby preventing dust and impurities from adhering to the film surface, reducing the formation of micro-channels on the film surface, and improving the barrier ability of the film to dust and impurities in the air, meeting the high requirements of food packaging. And this output method can match the film transmission rate. When the film transmission rate is slow, the static electricity accumulation on the film surface is relatively slow. At this time, the intermittently output antistatic spray can be supplemented at appropriate time intervals, which can not only effectively neutralize the static electricity on the film surface but also avoid wasting resources or having unnecessary impacts on the film surface due to overly frequent spraying. On the contrary, when the film transmission rate is fast, the static electricity generation rate increases, and at this time, the rotation speed of the convex plate shaft also increases synchronously, and thus the output frequency of the nozzle can be correspondingly increased to meet the static electricity protection requirements during the rapid film transmission process.
[0027] Among them, by continuously adding an antistatic spray into the nozzle through a curved connecting pipe, based on the principle of fluid continuity, a stable fluid system is formed between the two, ensuring balance between input and output. During this process, the nozzle continuously sprays the antistatic spray, while the curved connecting pipe continuously replenishes it, ensuring the continuous supply of the antistatic spray throughout the processing. This avoids the situation of reprocessing due to a decrease in the quality of the film caused by static electricity problems, enabling the film production to proceed continuously and stably, improving the efficiency of the entire production process, and adding the antistatic spray in a replenishing manner according to the spraying amount of the nozzle, avoiding waste caused by excessive addition of the antistatic spray at one time.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] It should be noted that the structures and working principles of the above-mentioned devices such as the base frame 1, the first unwinding group 11, the winding roller 12, the second unwinding assembly 13, the coating module 14, the thermal compounding module 15, and the cooling module 16 belong to the prior art and will not be elaborated herein.
[0032] Embodiment 1: Please refer to Figures 1 to 3 As shown, a heat treatment film positioning laminating machine is used for thermally laminating a film body 17, including a base frame 1. A first unwinding assembly 11 is installed at the bottom left of the base frame 1. A winding roller 12 is installed on the right side of the first unwinding assembly 11. A second unwinding assembly 13 is installed at the bottom right of the base frame 1. A coating module 14 is installed on the right side of the second unwinding assembly 13. A thermal compounding module 15 is installed above the first unwinding assembly 11. A cooling module 16 is installed on the right side of the thermal compounding module 15. A gradual transition mechanism 2 is arranged between the thermal compounding module 15 and the cooling module 16. A winding pretreatment mechanism 3 is arranged above the gradual transition mechanism 2. The gradual transition mechanism 2 is used for temperature compensation of the film body 17 after thermal compounding, and the winding pretreatment mechanism 3 is used for pretreatment of the film body 17 before winding.
[0033] It should be noted that the thermal compounding module 15 mainly includes a pressure sensor, a tension roller, and heating rollers symmetrically distributed up and down. The turbine shaft 25 is in transmission connection with the heating rollers in the thermal compounding module 15 through a belt. The convex plate shaft 32 is in transmission connection with the tension roller in the cooling module 16 through a belt. The cooling module 16 mainly includes a temperature sensor, a water pump, and a cooling roller. The cooling roller in the cooling module 16 and the heating rollers in the thermal compounding module 15 are on the same horizontal plane. The coating module 14 mainly includes a glue tank container for storing adhesives and a coating roller matching the diameters and lengths of the heating rollers and the cooling rollers.
[0034] Specifically, first, the film body 17 is respectively placed on the first unwinding assembly 11 and the second unwinding assembly 13. This is the starting step of the operation of the entire device. The two unwinding assemblies provide the film raw materials for the subsequent processing process. Secondly, when the film body 17 on the second unwinding assembly 13 starts to run, it passes through the gluing module 14 for gluing treatment. The glue tank container in the gluing module 14 stores the adhesive, and the coating roller evenly coats the adhesive on the surface of the film body 17. The film body 17 in the second unwinding assembly 13 after gluing treatment starts to move towards the thermal compounding module 15 through the transmission device. At the same time, the film body 17 in the first unwinding assembly 11 also moves towards the position of the thermal compounding module 15 driven by the corresponding transmission device. In the thermal compounding module 15, the heating rollers symmetrically distributed up and down are the key components. The film bodies 17 from the second unwinding assembly 13 and the second unwinding assembly 13 after gluing treatment are thermally bonded here. Finally, the film body 17 after thermal compounding and bonding then enters the cooling module 16. The cooling roller in the cooling module 16 cools the bonded film body 17 under power drive, and then it is wound up.
[0035] Please refer to Figures 4 to 7 As shown, the gradient transition mechanism 2 includes a balance bin 21 fixedly connected to the side wall of the base frame 1. The film body 17 is slidably connected to the inside of the balance bin 21. Opposite top plate groups 22 are installed on both sides of the balance bin 21. Guide plates 24 are symmetrically and fixedly connected to the inside of the balance bin 21. A turbine shaft 25 is rotatably connected to the inside of the balance bin 21.
[0036] It should be noted that the opposite top plate group 22 includes two curved arc plates, and the two curved arc plates are respectively fixedly connected to the upper left vertex and the lower right vertex of the balance bin 21. Through slots 23 are respectively formed through the connection positions of the opposite top plate group 22 and the balance bin 21. The curved arc plate of the opposite top plate group 22 close to the thermal compounding module 15 has a gradually upwardly curved arc, and the curved arc plate of the opposite top plate group 22 close to the cooling module 16 has a gradually downwardly curved arc. The guide plates 24 are inclinedly installed along the tangent direction of the left through slot 23, and the guide plates 24 are symmetrically distributed with the turbine shaft 25 as a reference.
[0037] Specifically, since the turbine shaft 25 is drivingly connected to the heating roller in the thermal composite module 15 by a belt, when the device is in operation, the turbine shaft 25 inside the balance chamber 21 will rotate synchronously. Due to the fact that the curved arc plate of the top plate group 22 close to the thermal composite module 15 has a gradually upward-bending curvature, and the curved arc plate of the top plate group 22 close to the cooling module 16 has a gradually downward-bending curvature. According to the characteristics of hot air naturally rising and cold air naturally descending, the basis for this phenomenon is mainly the convection principle in thermodynamics and the thermal expansion and contraction properties of gases: Specifically, when air is heated, the movement of its molecules speeds up, resulting in the expansion of the air volume and a decrease in density. Therefore, hot air is lighter than cold air and will show a gradually rising flow pattern. On the contrary, after cold air is cooled, the molecular movement slows down, the distance between molecules shrinks, the air volume contracts, and the density increases. Therefore, cold air is heavier than hot air and will show a gradually descending flow pattern. Therefore, the hot air and cold air generated at the positions of the thermal composite module 15 and the cooling module 16 will flow along the arc surface of the curved arc plate. Since the inside of the balance chamber 21 is relatively sealed, according to Bernoulli's principle, the pressure is low where the gas flow rate is large, and the pressure is high where the flow rate is small. Therefore, when the turbine shaft 25 inside the balance chamber 21 rotates, the blades of the turbine shaft 25 will push the air in the chamber to move, increasing the flow rate of the air near the turbine shaft 25. There are through slots 23 opened on both the upper and lower sides of the chamber. The local low pressure caused by the rotation of the turbine shaft 25 in the chamber will form a pressure difference with the atmospheric pressure outside the chamber. Since the air pressure outside the chamber is greater than the air pressure near the turbine shaft 25 inside the chamber, the external gas will be sucked into the chamber through the through slots 23 under the action of the pressure difference. By this way, the temperature on the upper and lower surfaces of the film body 17 is compensated and adjusted, so that the film body 17 reaches an almost consistent temperature before entering the cooling treatment, realizing the uniform distribution of the temperature of the film body 17. This improvement not only significantly improves the accuracy and stability of the thermal composite of the film body 17, but also helps to reduce the problem of inconsistent shrinkage rates of the film body 17 caused by temperature differences, thus improving the overall quality and performance of the film body 17.
[0038] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 8 to 10 As shown, the winding pretreatment mechanism 3 includes a storage cylinder 31 installed above the balance chamber 21. A convex plate shaft 32 is rotatably connected inside the storage cylinder 31. Elastic gasket rods 33 are uniformly slidably connected inside the storage cylinder 31. The lower ends of the elastic gasket rods 33 are slidably connected with spray pipes 34. Curved through pipes 35 are symmetrically installed inside the spray pipes 34.
[0039] It should be noted that a rectangular convex plate is fixedly connected to the outer wall of the convex plate shaft 32, a curved plate is evenly fixedly connected above the elastic gasket rod 33, the curved plate in the elastic gasket rod 33 is located on the moving path of the rectangular convex plate in the convex plate shaft 32, the interior of the storage cylinder 31 stores antistatic spray, the two ends of the curved tube 35 are respectively connected to the storage cylinder 31 and the nozzle 34, the elastic gasket rod 33 is located directly below the storage cylinder 31, and the elastic gasket rod 33 inside the nozzle 34 is initially located above the curved tube 35.
[0040] Specifically, since the convex plate shaft 32 is connected to the tension roller in the cooling module 16 through a belt transmission, when the device is in operation, the convex plate shaft 32 keeps rotating synchronously. When the convex plate shaft 32 rotates to the bottom of the storage tube 31, the convex plate in the convex plate shaft 32 will contact with the curved plate in the elastic gasket rod 33 and continue to press the curved plate downward. At this time, the space inside the nozzle 34 gradually becomes smaller, and the air pressure inside the nozzle 34 is greater than the air pressure outside the nozzle 34, thereby generating thrust inside the nozzle 34 to compress the internal resistance of the nozzle 34. The electrostatic spray is sprayed into the balance chamber 21. As the convex plate shaft 32 continues to rotate, the convex plate in the convex plate shaft 32 will be staggered with the curved plate in the elastic gasket rod 33. At this time, the elastic gasket rod 33 moves upward to restore to its original position by its own elastic force. At this time, the space inside the nozzle 34 gradually becomes larger, and the air pressure inside the nozzle 34 is less than the air pressure outside the nozzle 34, so that suction is generated inside the nozzle 34, and the generated suction is absorbed by the curved tube 35 to the storage tube 31 to replenish the antistatic spray, from the electrostatic In principle, the antistatic spray can neutralize the static electricity generated on the surface of the film body 17 during the processing, and produce an antistatic layer on the surface of the film body 17, thereby preventing dust and impurities from being adsorbed on the surface of the film body 17, reducing the formation of micro-channels on the surface of the film body 17, thereby improving the film body 17's ability to block dust and impurities in the air, so that it meets the high requirements of food packaging, and this output method can match the transmission rate of the film body 17. When the transmission rate of the film body 17 is slow, the static electricity accumulation on the surface of the film body 17 is relatively slow. At this time, the intermittently output antistatic spray can be replenished at appropriate time intervals, which can effectively neutralize the static electricity on the surface of the film body 17, and will not cause waste of resources or unnecessary impact on the surface of the film body 17 due to too frequent spraying. On the contrary, when the transmission rate of the film body 17 is fast, the static electricity generation rate is accelerated, and at this time the rotation speed of the convex plate shaft 32 is also accelerated synchronously, and then the output frequency of the nozzle 34 can be correspondingly increased to meet the static electricity protection needs during the rapid transmission of the film body 17.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
