Description

Technical Field

[0001] This application relates to the field of heat shrink film encapsulation technology, and in particular to a heat shrink film encapsulation system for producing mineral wool board prefabricated modules. Background Technology

[0002] Mineral wool prefabricated modules, widely used in building and industrial insulation materials, involve multiple processes in their production, with heat-shrink film encapsulation being a crucial step in ensuring product quality. As market demands for product quality increase, the development of heat-shrink film encapsulation technology is of great significance for improving the overall performance of mineral wool prefabricated modules. Traditional heat-shrink film encapsulation processes use specific equipment to tightly wrap the outer film of the mineral wool prefabricated module, effectively protecting it from environmental influences and significantly enhancing its aesthetics and durability, playing an irreplaceable role in practical applications.

[0003] In practical terms, the industry has developed several mature solutions for the effective shrink wrapping of the outer film of prefabricated mineral wool board modules. The most common is the traditional method based on a single heating mode, such as directly using electric heating elements to treat the target area at high temperatures, thereby rapidly softening the plastic material and conforming it to the object's surface shape. Meanwhile, some companies have also attempted to incorporate forced air circulation systems, using high-speed airflow to further enhance heat transfer and achieve faster and better shaping. However, since most existing equipment relies solely on the assembly of standard parts with fixed dimensions, it is difficult to accurately match the actual needs of the workpiece, leading to uneven local temperature distribution.

[0004] Regarding the aforementioned technologies, although numerous technical solutions for heat-shrink film encapsulation of prefabricated mineral wool board modules have emerged in the market, most remain at the stage of minor modifications to existing simple mechanisms, failing to fundamentally solve the pain points and difficulties such as low efficiency and poor adaptability. Especially when facing increasingly stringent quality standards, the traditional heat-shrink channel design has clearly exposed many shortcomings, and problems such as disjointed subsequent processes due to the lack of an effective cooling mechanism are becoming increasingly prominent. Therefore, there is an urgent need for a new heat-shrink film encapsulation system for prefabricated mineral wool board modules that can significantly improve work efficiency while ensuring sufficient flexibility and reducing operating costs. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a heat-shrink film encapsulation system for the production of mineral wool board prefabricated modules.

[0006] This application provides a heat-shrink film packaging system for producing prefabricated mineral wool board modules, which adopts the following technical solution:

[0007] A heat-shrink film packaging system for producing prefabricated mineral wool board modules includes a feeding mechanism and a heat-sealing mechanism. The heat-sealing mechanism includes a heat-shrinking assembly and a cooling assembly. The heat-shrinking assembly includes a heat-shrinking channel with partition plates at both ends. A sliding frame is mounted on the heat-shrinking channel, and the partition plates are slidably connected to the sliding frame to close or open the heat-shrinking channel. A plurality of heat-shrinking support frames are evenly distributed on the inner wall of the heat-shrinking channel, and a plurality of heating tubes are mounted on the heat-shrinking support frames. The system also includes a plurality of heat-shrinking fans mounted on the inner wall of the heat-shrinking channel. The heat-shrinking fans are connected to the heat-shrinking support frames. The number of frames corresponds one-to-one. The air outlet of the heat shrink blower points to the heating tube. The heat shrink blower is used to blow hot air onto the mineral wool board prefabrication module, heating the heat shrink film covering the mineral wool board prefabrication module and causing the heat shrink film to shrink. An infrared emitting mechanism is set on the inner wall of the heat shrink channel. The infrared emitting mechanism is used to heat shrink the mineral wool board prefabrication module. A conveying mechanism is set in the hot air mechanism and is used to feed the mineral wool board prefabrication module. A discharging mechanism is used to discharge the heat-sealed mineral wool board prefabrication module.

[0008] By adopting the above technical solution, the prefabricated mineral wool board module achieves efficient and comprehensive heat shrinking during the encapsulation process of the outer heat shrink film. Specifically, inside the heat shrinking channel, multiple heat shrinking support frames and their corresponding heating pipes, working in conjunction with the heat shrinking fan, ensure that heat is accurately transferred to the heat shrink film covering the outer surface of the prefabricated mineral wool board module. This causes the heat shrink film to shrink rapidly and adhere tightly to the surface of the prefabricated mineral wool board module, with the heat shrinking fan completing the overall heat shrinking. An infrared emitting mechanism shrinks the heat shrink film in areas with poor heat absorption, such as corners. Simultaneously, sliding partitions at both ends of the heat shrinking channel effectively reduce the impact of ambient temperature on the heat shrinking process, improving heat shrinking efficiency and quality consistency. Furthermore, the infrared emitting mechanism distributed on the inner wall of the heat shrinking channel further enhances the heat shrinking effect on the prefabricated mineral wool board module. Especially when dealing with heat shrink films of different materials or thicknesses, this design allows for flexible adjustment of radiation intensity to adapt to actual needs. Following precise heat shrinking, the product enters a cooling module area composed of multiple air-cooled fans. Directional airflow rapidly cools and solidifies the prefabricated mineral wool board modules, ensuring a stable final product shape and a smooth appearance. The entire process also includes a dedicated material handling and scheduling system, specially designed with complex path planning (such as an S-shaped layout) to extend effective operating time without increasing overall equipment size, and to ensure more even heating of the casing. Finally, the unloading mechanism smoothly outputs the processed product, ensuring optimal automation and production efficiency for the entire system.

[0009] Preferably, the feeding mechanism includes a feeding support frame disposed on one side of the heat shrink channel, a plurality of feeding rollers rotatably connected to the feeding support frame, the feeding rollers being horizontally disposed, a transmission part being disposed at one end of the feeding rollers, and a feeding power assembly disposed on the feeding support frame, the feeding power assembly being used to drive the feeding rollers to rotate.

[0010] By adopting the above technical solution, the feeding mechanism can achieve stable and reliable feeding of mineral wool board prefabricated modules. Specifically, the feeding support frame set on one side of the heat shrink channel provides a solid foundation for the entire feeding structure, and multiple horizontally arranged feeding rollers can effectively support and transport the mineral wool board prefabricated modules, ensuring their smooth movement. At the same time, through the cooperation of the transmission unit and the feeding power assembly, the feeding rollers are powered, thereby ensuring that the mineral wool board prefabricated modules accurately enter the subsequent heat shrinking process at a predetermined speed and direction, improving the system's automation level and work efficiency.

[0011] Preferably, the feed roller is provided with a friction surface, which is used to assist feeding.

[0012] By adopting the above technical solution, the friction surface set on the feed roller can significantly improve the friction between the feed roller and the mineral wool board prefabrication module, thereby effectively preventing slippage during the feeding process, ensuring that the mineral wool board prefabrication module is smoothly and accurately transferred into the heat shrink channel, and improving the overall system's operational stability and packaging efficiency.

[0013] Preferably, the feeding power assembly includes a feeding motor mounted on the feeding support frame, the transmission end of the feeding motor being provided with a drive wheel, and a driven wheel mounted on the feeding support frame. A transmission belt is provided between the drive wheel and the driven wheel, and the transmission belt is capable of driving the transmission unit to rotate.

[0014] By adopting the above technical solution, the mineral wool board prefabrication module can achieve stable transmission under the drive of the feeding motor. Specifically, the feeding motor drives the feeding roller to rotate through the transmission belt between the driving wheel and the driven wheel, thereby ensuring the smooth feeding of the mineral wool board prefabrication module, avoiding jamming or deviation, and improving the operating efficiency and reliability of the packaging system.

[0015] Preferably, the infrared emitting mechanism includes an infrared support frame disposed on the inner wall of the heat-shrinkable channel, an infrared motor disposed on the infrared support frame, a first equal-diameter oblique bevel gear disposed on the transmission end of the infrared motor, a second equal-diameter oblique bevel gear being obliquely meshed on the first equal-diameter oblique bevel gear, a positioning component mounted on the infrared support frame, the positioning component being used to position the second equal-diameter oblique bevel gear so that the second equal-diameter oblique bevel gear can rotate along the axis of the first equal-diameter oblique bevel gear, a mounting rod being coaxially connected to the second equal-diameter oblique bevel gear, an infrared heat-shrinkable device disposed on the mounting rod, and a reflector being disposed around the infrared heat-shrinkable device, the reflector being used to focus infrared rays onto the surface of the mineral wool board prefabricated module.

[0016] By adopting the above technical solution, the infrared emitting mechanism can achieve precise heat transfer. Specifically, by utilizing the inclined meshing structure between the first and second equal-diameter oblique bevel gears, in conjunction with the positioning component, it is ensured that the mounting rod and its infrared heat-shrinking device can flexibly adjust their position within a specific space and maintain stable operation. Simultaneously, the reflector design effectively enhances the energy concentration of infrared rays, allowing heat to act more efficiently on areas with poor heat sealing, such as the edges and corners of the mineral wool board prefabricated module surface, during the heat-shrinking process, thereby significantly improving the uniformity, efficiency, and quality consistency of heat shrinking.

[0017] Preferably, the positioning component includes a guide rail disposed on the inner wall of the heat shrink tunnel, the guide rail being inclined, a positioning slider slidably connected to the guide rail, the positioning slider being able to slide within the guide rail, a positioning rod disposed on the positioning slider, a first positioning ring disposed on the positioning rod, and a second positioning ring disposed on the mounting rod, the second positioning ring being rotatably connected to the first positioning ring.

[0018] By adopting the above technical solution, the cooperation between the guide rail and the positioning slider allows the second equal-diameter oblique bevel gear to move within a precise angular range, thereby ensuring the accurate positioning of the infrared heat shrink device. This design not only improves the assembly precision of the equipment but also enhances the stability of infrared focusing, further improving the quality and efficiency of heat shrink film encapsulation.

[0019] Preferably, a positioning groove is provided on the inner surface of the first positioning ring, and the second positioning ring is embedded in the positioning groove.

[0020] By adopting the above technical solution, a stable connection between the first and second positioning rings is achieved. Specifically, the positioning groove allows the second positioning ring to rotate smoothly within the groove while maintaining a fixed position, thereby ensuring higher stability and accuracy of the mounting rod and its infrared heat-shrink device during operation. This design effectively improves the overall reliability of the infrared emitting mechanism and avoids infrared focusing deviation problems caused by loose components.

[0021] Preferably, the cooling assembly includes a cooling channel connected to the heat shrink tubing, and a plurality of air-cooled fans are provided on the cooling channel, with the air-cooled fans pointing towards the transport mechanism.

[0022] By adopting the above technical solution, the cooling component is connected to the heat-shrink channel through a cooling channel, and multiple air-cooled fans are arranged on the cooling channel, enabling the prefabricated mineral wool board modules to cool down rapidly after heat shrinking. The air blown by the air-cooled fans acts directly on the prefabricated mineral wool board modules on the transport mechanism, effectively improving cooling efficiency and preventing the prefabricated mineral wool board modules from deforming or being damaged due to high temperatures, thereby ensuring stable and reliable packaging quality.

[0023] Preferably, the transport mechanism includes a first conveyor belt disposed within the heat shrink channel and a second conveyor belt disposed within the cooling channel. The input end of the first conveyor belt is connected to the discharge end of the feeding mechanism, and the output end of the first conveyor belt is connected to the input end of the second conveyor belt. The output end of the second conveyor belt is connected to the feeding end of the discharging mechanism. The first conveyor belt can receive mineral wool board prefabricated modules from the discharge end of the feeding mechanism and transport them to the input end of the second conveyor belt. The second conveyor belt receives mineral wool board prefabricated modules from the output end of the first conveyor belt and transports them to the feeding end of the discharging mechanism. The first conveyor belt and the second conveyor belt are connected and arranged in a series of S-shapes.

[0024] By adopting the above technical solution, the design of the first and second conveyor belts enables the mineral wool board prefabricated modules to be smoothly transported between the heat shrink tunnel and the cooling tunnel. The first conveyor belt receives the mineral wool board prefabricated modules from the feeding mechanism, ensuring continuous material feeding. Both the first and second conveyor belts are arranged in multiple S-shapes within the heat shrink tunnel and the cooling tunnel, increasing the dwell time of the mineral wool board prefabricated modules in each functional area, thereby improving the quality of heat shrink film encapsulation and cooling efficiency. Specifically, the multiple S-shaped design of the first and second conveyor belts helps the mineral wool board prefabricated modules fully contact the heat generated by the heat shrink fan and the cooling airflow provided by the air-cooling fan, ensuring uniform shrinkage of the heat shrink film and tight bonding with the mineral wool board prefabricated modules, while accelerating the cooling process and improving the stability and reliability of the overall production system. Simultaneously, the position of the heat-sealed mineral wool board prefabricated modules can be adjusted during the feeding process, allowing the infrared emitting mechanism to irradiate the corners of the mineral wool board prefabricated modules, improving the heat sealing quality.

[0025] Preferably, the discharge mechanism includes a discharge guide slope disposed on one side of the cooling channel, and a guide groove is provided on the discharge guide slope.

[0026] By adopting the above technical solution, the mineral wool board prefabricated module, after being encapsulated with heat-shrink film, can achieve a smooth transition during the discharge stage using the discharge guide slope, avoiding impact or damage caused by height differences. Simultaneously, the guide groove design effectively guides the movement direction of the mineral wool board prefabricated module, ensuring accurate discharge along the predetermined path and improving the stability and reliability of the entire system.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The heat shrink support frame, heating tube and heat shrink fan configured inside the heat shrink channel work together to accurately control the heating process of the outer heat shrink film of the mineral wool board prefabricated module, ensure uniform heat distribution and prevent sealing defects caused by temperature difference in traditional methods.

[0029] The infrared emitting mechanism utilizes an adjustable infrared heat shrink device and reflector, which not only enhances heat shrink efficiency and reduces energy consumption, but also specifically improves the problem of poor heat sealing effect at corners, thereby comprehensively improving the heat sealing quality.

[0030] The unique design of the cooling components combined with the transport mechanism allows the prefabricated mineral wool board modules that have completed the heat shrinking process to cool down quickly, reducing the total processing cycle and preventing damage and deformation of the heat shrink film, thereby enhancing the continuous operating efficiency and output of the equipment.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application provides a heat-shrink film packaging system for producing prefabricated mineral wool board modules, which adopts the following technical solution:

[0041] refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 A heat-shrink film encapsulation system for producing mineral wool board prefabricated modules includes a feeding mechanism 1 for conveying mineral wool board prefabricated modules, which are composed of multiple stacked mineral wool boards covered with unshrinkable heat-shrinkable film; a heat-sealing mechanism 2 for heating the mineral wool board prefabricated modules to shrink the heat-shrinkable film covering them; an infrared emitting mechanism 3 for heat-shrinking the mineral wool board prefabricated modules; a transport mechanism 4 for feeding the mineral wool board prefabricated modules; and a discharge mechanism 5 for discharging the heat-sealed mineral wool board prefabricated modules.

[0042] In actual operation, the mineral wool board prefabrication module is first fed into the conveying mechanism 4 through the feeding mechanism 1. The conveying mechanism 4 carries the mineral wool board prefabrication module in the heat sealing mechanism 2. During the movement, the heat sealing mechanism 2 works to shrink the heat shrink film on the mineral wool board prefabrication module. After the mineral wool board prefabrication module is heat-shrinked, it is further cooled down. Finally, the unloading mechanism 5 smoothly outputs the processed product, fully ensuring that the automation level and production efficiency of the whole system reach the optimal state.

[0043] refer to Figure 1 Specifically, the heat-sealing mechanism 2 includes a heat-shrinking assembly 201 and a cooling assembly 202. The heat-shrinking assembly 201 includes a heat-shrinking channel 2011, with partition plates 2012 at both ends of the channel. A sliding frame 2017 is mounted on the channel, and the partition plates 2012 are slidably connected to the sliding frame 2017. A power device 2013 is mounted on the partition plate 2012, driving the partition plate 2012 to perform vertical reciprocating motion. As one embodiment, the power device 2013 can be a cylinder or a sliding module, etc. Taking a cylinder as an example, the movable end of the cylinder is mounted on the partition plate 2012, and the fixed end is connected to the outer wall of the heat-shrinking channel 2011, driving the partition plate 2012 to move vertically. The heat shrinking channel 2011 has several heat shrinking support frames 2014 evenly distributed on its inner wall. Several heating tubes 2015 are installed on the heat shrinking support frames 2014. The heat shrinking assembly 201 also includes several heat shrinking fans 2016 installed on the inner wall of the heat shrinking channel 2011. Each heat shrinking fan 2016 corresponds to one heat shrinking support frame 2014. Each heat shrinking support frame 2014 is equipped with a set of heat shrinking fans 2016. The air outlet of each heat shrinking fan 2016 points to the heating tube 2015 on the corresponding heat shrinking support frame 2014. The heat shrinking fan 2016 is used to blow hot air onto the mineral wool board prefabricated module, causing the heat shrink film covering the mineral wool board prefabricated module to shrink.

[0044] refer to Figure 5The cooling assembly 202 includes a cooling channel 2021, which is connected to the heat shrink channel 2011. Several air-cooled fans 2022 are installed on the cooling channel 2021, and the air-cooled fans 2022 point towards the transport mechanism 4.

[0045] In practice, the mineral wool board prefabricated module enters the heat shrink channel 2011 via the transport mechanism 4 and moves within it. Multiple heat shrink support frames 2014, along with their corresponding heating pipes 2015 and heat shrink blowers 2016, ensure precise heat transfer to the heat shrink film covering the outer surface of the mineral wool board prefabricated module. This causes the heat shrink film to shrink rapidly and adhere tightly to the surface of the mineral wool board prefabricated module. The heating pipes 2015 are heated by electric heating or other methods, and the heat generated by the heat shrink blowers 2016 is blown onto the mineral wool board prefabricated module on the transport mechanism 4, causing the heat shrink film to shrink. Simultaneously, because sliding partition plates 2012 are installed at both ends of the heat shrink channel 2011, the partition plates 2012 are closed when there is a mineral wool board in the heat shrink channel 2011, effectively preventing the influence of external ambient temperature on the heat shrinking process and improving heat shrinking efficiency. The cooling assembly 202 is connected to the heat shrinking channel 2011 through the cooling channel 2021, and multiple air-cooled fans 2022 are arranged on the cooling channel 2021. The air-cooled fans 2022 generate cold air and blow it onto the mineral wool board prefabricated module, so that the mineral wool board prefabricated module after heat shrinking can be cooled down quickly, effectively improving the cooling efficiency and preventing the mineral wool board prefabricated module from deforming or being damaged due to high temperature, thereby ensuring stable and reliable packaging quality.

[0046] refer to Figure 6 Specifically, the feeding mechanism 1 includes a feeding support frame 101 disposed on one side of the heat shrink channel 2011. A plurality of feeding rollers 102 are rotatably connected to the feeding support frame 101. Friction surfaces 105 are provided on the feeding rollers 102 to assist feeding. The feeding rollers 102 are horizontally arranged, and a transmission unit 103 is provided at one end of each feeding roller. The mechanism also includes a feeding power assembly 104 disposed on the feeding support frame 101. The feeding power assembly 104 drives the feeding rollers 102 to rotate. The feeding power assembly 104 includes a feeding motor 1041 disposed on the feeding support frame 101. A drive wheel 1042 is provided at the transmission end of the feeding motor 1041. A driven wheel 1043 is also disposed on the feeding support frame 101. A transmission belt 1044 is disposed between the drive wheel 1042 and the driven wheel 1043, and the transmission belt 1044 can drive the transmission unit 103 to rotate.

[0047] In actual operation, the feeding motor 1041 operates, which in turn drives the feeding roller 102 to rotate through the transmission belt 1044 between the driving wheel 1042 and the driven wheel 1043. The friction surface 105 provided on the feeding roller 102 can significantly increase the friction between it and the mineral wool board prefabrication module, thereby effectively preventing slippage during the feeding process. The feeding mechanism 1 can achieve stable and reliable feeding of the mineral wool board prefabrication module.

[0048] refer to Figure 3 as well as Figure 4 Specifically, the infrared emitting mechanism 3 includes an infrared support frame 301 mounted on the inner wall of the heat shrink channel 2011, an infrared motor 302 mounted on the infrared support frame 301, a first equal-diameter oblique bevel gear 303 mounted on the transmission end of the infrared motor 302, and a second equal-diameter oblique bevel gear 304 rotatably connected to the infrared support frame 301. The first equal-diameter oblique bevel gear 303 and the second equal-diameter oblique bevel gear 304 are obliquely meshed. A positioning component 305 is mounted on the infrared support frame 301 for positioning the second equal-diameter oblique bevel gear 304. The positioning component 305 includes a guide rail 3051 mounted on the inner wall of the heat shrink channel 2011, the guide rail 3051 being obliquely arranged, and a positioning slider 3052 slidably connected to the guide rail 3051. A positioning rod 3053 is provided on the 052, and a first positioning ring 3054 is provided on the positioning rod 3053. It also includes a second positioning ring 3055 provided on the mounting rod 306. The second positioning ring 3055 is rotatably connected to the first positioning ring 3054. A positioning groove 3056 is provided on the inner surface of the first positioning ring 3054. The second positioning ring 3055 is embedded in the positioning groove 3056, so that the second equal diameter oblique bevel gear 304 can rotate along the axis of the first equal diameter oblique bevel gear 303. The mounting rod 306 is coaxially connected to the second equal diameter oblique bevel gear 304. An infrared heat shrinking device 307 is provided on the mounting rod 306. It also includes a reflector 308. The reflector 308 is arranged around the infrared heat shrinking device 307. The reflector 308 is used to focus infrared rays onto the surface of the mineral wool board prefabricated module.

[0049] In practice, the prefabricated mineral wool board module is fed into the heat shrinking channel 2011 by the transport mechanism 4. The heat shrinking assembly 201 then performs heat shrinking. After the initial heat shrinking is completed, the infrared emitting mechanism 3 starts working, and the infrared heat shrinking device 307 emits infrared light waves. The direction is further confirmed by the reflector 308. As the transport mechanism 4 moves within the heat shrinking channel 2011, the infrared motor 302 drives the first equal-diameter oblique bevel gear 303, which in turn drives the second equal-diameter oblique bevel gear 304 to rotate. Through the transmission of the first positioning ring 3054, the second positioning ring 3055, and the positioning rod 3053, the positioning slider 3052 rotates along the guide rail 3051, which in turn drives the mounting rod 306 to rotate. This controls the direction of the infrared heat shrinking device 307 and further controls the direction of the infrared light waves. This reinforces areas where the heat shrinking effect of the heat shrinking assembly 201 is poor, such as overlapping corners and uneven heating areas, thereby significantly improving heat shrinking efficiency and quality consistency.

[0050] refer to Figure 1 Specifically, the transport mechanism 4 includes a first conveyor belt 401 disposed within the heat shrink tunnel 2011 and a second conveyor belt 402 disposed within the cooling tunnel 2021. The input end of the first conveyor belt 401 is connected to the output end of the feeding mechanism 1, and the output end of the first conveyor belt 401 is connected to the input end of the second conveyor belt 402. The output end of the second conveyor belt 402 is connected to the feeding end of the discharging mechanism 5. The first conveyor belt 401 can receive mineral wool board prefabricated modules from the output end of the feeding mechanism 1 and transport them to the second conveyor belt. At the input end of 402, the second conveyor belt 402 receives the mineral wool board prefabrication module from the output end of the first conveyor belt 401 and transports it to the feed end of the discharge mechanism 5. The first conveyor belt 401 and the second conveyor belt 402 are connected. The first conveyor belt 401 and the second conveyor belt 402 can be arranged in a straight line or in a wavy shape. The wavy arrangement of the first conveyor belt 401 and the second conveyor belt 402 is more effective than the straight arrangement, which can extend the effective working time of the mineral wool board prefabrication module in the heat shrink channel 2011 and the cooling channel 2021. (Reference) Figure 1 and Figure 7In a preferred embodiment, the first conveyor belt 401 and the second conveyor belt 402 are arranged in multiple S-shapes, with the multiple S-shapes connected end to end in sequence. During operation, the mineral wool board prefabricated module is fed onto the first conveyor belt 401 via the feeding device 1, and then moves within the heat shrinking channel 2011. After operation within the heat shrinking channel 2011, the mineral wool board prefabricated module is fed onto the second conveyor belt 402, and then moves within the cooling channel 2021 via the second conveyor belt 402. During this movement, due to the bending arc during transport, the mineral wool board prefabricated module can also rotate to adjust its direction, resulting in more uniform heating. This design allows the mineral wool board prefabricated module to extend the transport time and change its placement state between the heat shrinking channel 2011 and the cooling channel 2021. The width of the first conveyor belt 401 and the second conveyor belt 402 allows the mineral wool board prefabricated module to rotate freely without jamming. The first conveyor belt 401 receives mineral wool board prefabrication modules from the feeding mechanism 1, ensuring continuous material feeding. Both the first conveyor belt 401 and the second conveyor belt 402 are arranged in multiple S-shapes within the heat shrink channel 2011 and the cooling channel 2021, increasing the dwell time of the mineral wool board prefabrication modules in each functional area, thereby improving the quality of heat shrink film encapsulation and cooling efficiency. Specifically, the multiple S-shaped design of the first conveyor belt 401 and the second conveyor belt 402 helps the mineral wool board prefabrication modules fully contact the heat generated by the heat shrink blower 2016 and the cooling airflow provided by the air-cooled blower 2022, ensuring uniform shrinkage of the heat shrink film and tight bonding with the mineral wool board prefabrication modules, while accelerating the cooling process and improving the stability and reliability of the overall production system. Simultaneously, the position of the heat-sealed mineral wool board prefabrication modules can be adjusted during feeding, allowing the infrared emitting mechanism 3 to irradiate the corners of the mineral wool board prefabrication modules, improving the heat sealing quality.

[0051] refer to Figure 1 Specifically, the discharge mechanism 5 includes a discharge guide slope 501 set on one side of the cooling channel 2021, and a guide groove 502 is provided on the discharge guide slope 501.

[0052] In actual operation, after the mineral wool board prefabrication module is encapsulated with heat-shrink film, it can achieve a smooth transition during the discharge stage using the discharge guide slope 501, avoiding impact or damage caused by height differences. At the same time, the design of the guide groove 502 effectively guides the movement direction of the mineral wool board prefabrication module, ensuring that it is accurately discharged along the predetermined path, thereby improving the stability and reliability of the entire system.

[0053] The implementation principle of the mineral wool board prefabricated module production heat shrink film packaging system in this application embodiment is as follows: This packaging system adopts a modular design concept, with each part working collaboratively to form a closed-loop, highly efficient, automated production line. First, the feeding mechanism 1, through the combined design of the feeding roller 102 and the feeding power component 104, can stably and reliably transport the mineral wool board to the next stage—the heat sealing mechanism 2. During this process, the special material selection and surface treatment of the feeding roller 102 greatly enhance the friction performance, avoiding problems such as positional displacement caused by slippage. Next, it reaches the heat shrink channel 2011, where the partition plate 2012 is cleverly used to separate the chambers. At the same time, with the help of multiple built-in heating elements and matching air supply devices, a comprehensive three-dimensional heating system is constructed to ensure that every corner receives sufficient and uniform energy supply, thereby achieving the ideal heat shrink result.
