Description

A high-safety wire mesh heat sealing device Technical Field

[0001] This application relates to the field of solar printing screen manufacturing technology, specifically to a high-safety screen heat sealing device. Background Technology

[0002] In the manufacturing process of solar-powered printing screens, the heat-sealing process plays a crucial role. Its quality directly affects the final performance and lifespan of the solar-powered printing screen.

[0003] Traditional screen printing heat sealing equipment, in pursuit of ease of operation, mostly adopts an open design. During the heat sealing process, the PI film used on the screen plays a crucial role. However, the solvents and other volatile substances contained in the PI film experience a sharp decline in stability at high temperatures, making them highly volatile. Some of these volatile substances are hazardous; for example, certain organic volatiles can irritate the respiratory tract. Long-term exposure significantly increases the risk of respiratory diseases for operators, causing considerable damage to their health. Working in such an environment for extended periods may also expose operators to various health risks related to the nervous and immune systems.

[0004] Furthermore, considering the working principle of the heat-sealing equipment, while the heating plate precisely heats the heat-sealing area, it inevitably conducts heat to the surrounding area, thus heating the surrounding polyester mesh. The physical properties of the polyester mesh are extremely sensitive to temperature; even slight temperature changes can alter its internal structure. During the heat-sealing process, the tensile strength, flexibility, and other key physical properties of the polyester mesh surrounding the heat-sealing area are significantly affected by the heat. This not only reduces the quality of the polyester mesh itself but may also lead to deformation and changes in mesh size during subsequent use of the entire screen, severely impacting the printing accuracy and quality of the solar cell printing screen, and consequently affecting the production efficiency and performance of solar cells.

[0005] In summary, the open design of traditional screen printing heat sealing equipment has significant shortcomings in terms of operator health protection and protection of screen printing material performance. There is an urgent need to develop new, highly safe screen printing heat sealing equipment to solve these problems. Summary of the Invention

[0006] In order to solve the technical problems in the prior art, this application provides a high-security wire mesh heat sealing device.

[0007] The high-safety screen heat sealing device provided in this application adopts the following technical solution:

[0008] A high-safety wire mesh heat sealing device, comprising:

[0009] The housing has a sealed cavity inside, and an operating window that can be opened or closed is provided on the housing.

[0010] A heating mechanism, comprising a frame and a heating plate, wherein a first water-cooling channel is formed within the frame, and the heating plate is disposed within the frame; the upper surfaces of the frame and the heating plate are used to hold polyester mesh and metal mesh.

[0011] A cooling mechanism for introducing coolant into the first water-cooling channel;

[0012] A pressing mechanism, used to press the polyester mesh and metal mesh against the upper surface of the heating plate; and,

[0013] The exhaust mechanism has its inlet connected to the receiving cavity.

[0014] By adopting the above technical solution, and designing the equipment with a sealed housing structure, coupled with an exhaust mechanism, harmful substances volatilized from the PI film during the heat-sealing process can be effectively collected and removed. This greatly reduces the operator's contact with harmful volatiles, lowers the risk of respiratory diseases, effectively protects the operator's nervous and immune systems, improves the working environment, and safeguards the operator's health. Simultaneously, the cooling mechanism introduces coolant into the first water-cooling channel of the frame, allowing the frame to absorb and remove some heat during heat sealing, preventing excessive heat conduction from the heating plate to the periphery of the heat-sealing area. The impact of heat on the periphery of the polyester mesh heat-sealing area is significantly reduced, thus preserving its physical properties.

[0015] Preferably, the heating mechanism further includes a shelf, which is disposed inside the housing, and the shelf has a groove, and the frame is fixed in the groove.

[0016] By adopting the above technical solution, the shelf is set inside the shell, and the frame is fixed in the groove of the shelf. This structural design provides a stable installation foundation for the heating mechanism.

[0017] Preferably, the shelf has a second water-cooling channel and a third water-cooling channel. One end of the second water-cooling channel is connected to one end of the first water-cooling channel, and one end of the third water-cooling channel is connected to the other end of the first water-cooling channel. The cooling mechanism includes a coolant tank, an inlet pump, an inlet pipe, an inlet valve, an outlet pipe, an outlet valve, and a refrigeration component. The coolant tank is used to store coolant. The inlet of the inlet pump is connected to the coolant tank, and the outlet of the inlet pump is connected to one end of the inlet pipe. The other end of the inlet pipe is connected to the other end of the second water-cooling channel. The inlet valve is disposed on the inlet pipe. One end of the outlet pipe is connected to the other end of the third water-cooling channel, and the other end of the outlet pipe is connected to the coolant tank. The outlet valve is disposed on the outlet pipe. The refrigeration component is used to cool the coolant in the coolant tank.

[0018] By adopting the above technical solution, a complete coolant circulation system is formed through the connection of the second and third water-cooling channels with the first water-cooling channel. This system can more efficiently remove the heat generated by the heating plate, effectively reduce the heating impact on the polyester mesh fabric surrounding the heat-sealing area, and improve the heat-sealing quality.

[0019] Preferably, the cooling component includes a temperature sensor and a semiconductor cooling component. The temperature sensor is disposed inside the coolant tank, the cold end of the semiconductor cooling component is located inside the coolant tank, and the hot end of the semiconductor cooling component is located outside the coolant tank.

[0020] By adopting the above technical solution, and through the coordinated operation of temperature sensors and semiconductor cooling components, large fluctuations in coolant temperature can be effectively avoided. This helps reduce damage to the heating mechanism and other components caused by temperature instability, extends the service life of the equipment, and improves the reliability and stability of the system.

[0021] Preferably, the pressing mechanism includes a pressing cylinder and a pressure plate. The fixed end of the pressing cylinder is fixed to the housing, and the output end of the pressing cylinder is fixedly connected to the pressure plate. The pressure plate is used to press the polyester mesh and metal mesh placed on the heating plate.

[0022] By adopting the above technical solution, the fixed end of the clamping cylinder is fixed to the housing, which ensures good stability of the clamping cylinder during operation. When the cylinder is activated, it can stably transmit force to the pressure plate, ensuring that the pressure plate applies stable pressure to the polyester mesh and metal mesh, thereby guaranteeing the stability of the heat sealing quality.

[0023] Preferably, the housing has an air inlet, a filter is provided inside the air inlet, and the housing also has an exhaust port; the exhaust mechanism includes an exhaust hood, an exhaust fan and a waste gas treatment device, the exhaust hood is fixed above the pressure plate, the outlet of the exhaust hood is connected to the air inlet, the inlet of the exhaust fan is connected to the air inlet, and the outlet of the exhaust fan is connected to the inlet of the waste gas treatment device.

[0024] By adopting the above technical solution, the suction hood is located above the pressure plate, which can efficiently collect these exhaust gases. The exhaust gases enter the exhaust fan through the air inlet and are then transported to the exhaust gas treatment equipment. The exhaust gas treatment equipment can purify the exhaust gases, remove harmful substances, and ensure that the emitted gases meet environmental protection standards, effectively improving workplace air quality and protecting the health of operators.

[0025] Preferably, the high-safety wire mesh heat sealing equipment further includes several clamping mechanisms. Each clamping mechanism includes a fixed column, a swing rod, a pressure rod, and a telescopic drive component. The fixed column is fixed to the frame, the middle part of the swing rod is hinged to the fixed column, one end of the pressure rod is fixed to one end of the swing rod, one end of the telescopic drive component is hinged to the fixed column, and the other end of the telescopic drive component is hinged to the other end of the pressure rod.

[0026] By adopting the above technical solution, after the polyester mesh and metal mesh are placed on the heating plate, the clamping mechanism can quickly pre-clamp their outer edges. Since the fixing posts are fixed to the frame, and the swing rod, pressure rod, and telescopic drive cooperate with each other, the mesh and metal mesh can be precisely positioned in the predetermined positions. This ensures that they are in an accurate initial position before the subsequent clamping mechanism operates, avoiding poor heat sealing caused by positional deviations, such as uneven edges and loose adhesion, thus improving the accuracy of heat sealing and product quality.

[0027] Preferably, the high-safety wire mesh heat sealing equipment further includes a flipping mechanism, which includes a rotating shaft and a flipping drive. The rotating shaft is rotatably disposed within the housing and extends horizontally. Two heating mechanisms are respectively disposed on both sides of the rotating shaft. The shelves of the two heating mechanisms are respectively fixed to both sides of the rotating shaft. Each shelf has a groove, and a frame is fixed in each groove. A heating plate is installed in each frame, and a plurality of clamping mechanisms are disposed on each frame. The flipping drive is connected to the rotating shaft and is used to drive the rotating shaft to rotate so that one of the shelves is located above the rotating shaft.

[0028] By adopting the above technical solution, using a dual heating mechanism and switching it between the two heating mechanisms, while one heating mechanism is performing heat sealing work, the other heating mechanism can be left to cool down naturally, reducing equipment downtime, achieving continuous production, and greatly improving production efficiency. If there is only one heating mechanism, it is necessary to wait for the heating mechanism to cool down after heat sealing before the next polyester mesh and metal mesh can be placed. Therefore, using a dual heating mechanism reduces equipment downtime and achieves continuous production.

[0029] Preferably, the flipping mechanism further includes a positioning component, which includes two positioning cylinders and a positioning telescopic member. The two positioning cylinders are respectively fixed on two opposite frames, and the fixed end of the positioning telescopic member is fixed to the housing. When one of the shelves is located above the rotating shaft and is horizontally set, the movable end of the positioning telescopic member can be inserted into the positioning cylinder fixed on the shelf.

[0030] By adopting the above technical solution, when the flipping drive rotates the shaft, positioning one of the shelves above the shaft and horizontally, the movable end of the positioning telescopic component inserts into the positioning cylinder fixed on the shelf. This precise fit ensures that the heating mechanism is in the accurate working position, guaranteeing the positional accuracy of the polyester mesh and metal mesh during the heat sealing process.

[0031] Preferably, a collection plate is also provided inside the housing, and the collection plate is located below the shelf.

[0032] By adopting the above technical solution, the collection plate provides a centralized collection area, allowing the heat-sealed products to be stacked in an orderly manner. Staff only need to collect the products from the collection plate periodically, which greatly improves the efficiency of product collection.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By designing the equipment with a sealed housing structure and a ventilation mechanism, harmful substances volatilized from the PI film during the heat-sealing process can be effectively collected and removed. This significantly reduces operators' exposure to harmful volatile substances, lowers the risk of respiratory diseases, effectively protects the operators' nervous and immune systems, improves the working environment, and safeguards the operators' health. Simultaneously, the cooling mechanism introduces coolant into the first water-cooling channel of the frame, allowing the frame to absorb and remove some heat during heat sealing, preventing excessive heat conduction from the heating plate to the periphery of the heat-sealing area. The impact of heat on the periphery of the polyester mesh heat-sealing area is greatly reduced, thus preserving its physical properties.

[0035] 2. After the polyester mesh and metal mesh are placed on the heating plate, the clamping mechanism can quickly pre-clamp their outer edges. Because the fixing posts are fixed to the frame, and the swing rod, pressure rod, and telescopic drive cooperate with each other, the mesh and metal mesh can be precisely positioned in the predetermined positions. This ensures they are in an accurate initial position before the subsequent clamping mechanism operates, avoiding poor heat sealing due to positional deviations, such as uneven edges and loose adhesion, thus improving heat sealing accuracy and product quality.

[0036] 3. Employing a dual heating mechanism and switching it between the two heating elements via a flipping mechanism allows the other heating element to cool down naturally while one is performing heat sealing operations. This reduces equipment downtime, enables continuous production, and significantly improves production efficiency. The flipping mechanism design allows the two heating elements to work alternately within a limited space, making full use of the internal space and resulting in a more compact structure and reduced footprint.

[0037] 4. When the flipping drive rotates the shaft, positioning one of the shelves above the shaft and horizontally, the movable end of the positioning telescopic component inserts into the positioning cylinder fixed on that shelf. This precise fit ensures the heating mechanism is in the accurate working position, guaranteeing the positional accuracy of the polyester mesh and metal mesh during the heat sealing process.

[0045] The present application will be further described in detail below with reference to Figures 1-6.

[0046] This application discloses a high-security screen heat sealing device.

[0047] Example 1

[0048] Referring to Figures 1-4, the high-safety mesh heat sealing equipment includes a housing 1, a heating mechanism 2, a cooling mechanism 3, a pressing mechanism 4, and a ventilation mechanism 5.

[0049] The housing 1 has a sealed cavity inside, and the housing 1 has an operating window 11 that can be opened or closed. In this embodiment, the main body of the operating window 11 is made of explosion-proof glass material, so that the operator can easily observe the inside of the housing 1.

[0050] The heating mechanism 2 includes a frame 21 and a heating plate 22. A first water-cooling channel 211 is formed inside the frame 21. The heating plate 22 is disposed inside the frame 21. The upper surfaces of the frame 21 and the heating plate 22 are used to place polyester mesh and metal mesh 6.

[0051] The cooling mechanism 3 is used to introduce coolant into the first water-cooling channel 211.

[0052] The pressing mechanism 4 is used to press the polyester mesh and metal mesh 6 onto the upper surface of the heating plate 22.

[0053] The inlet of the exhaust mechanism 5 is connected to the receiving cavity.

[0054] During use, the operator opens the operating window 11 and places the polyester mesh and metal mesh 6 on the frame 21 and the upper surface of the heating plate 22 of the heating mechanism 2. At this time, the cooling mechanism 3 begins to introduce coolant into the first water-cooling channel 211 inside the frame 21 to prepare the heating mechanism 2 for cooling in advance, preventing residual heat from the heating plate 22 from affecting the mesh placed subsequently. The pressing mechanism 4 is then activated to press the polyester mesh and metal mesh 6 tightly onto the upper surface of the heating plate 22, ensuring that the polyester mesh and metal mesh 6 are tightly adhered during the heat sealing process, thus improving the heat sealing effect. Next, the heating mechanism 2 is turned on, and the heating plate 22 begins to heat the area where the polyester mesh and metal mesh are connected, achieving heat sealing between the two. During this process, due to the presence of the first water-cooling channel 211 in the frame 21, some heat is carried away, reducing the heat conducted from the heating plate 22 to the surrounding area and minimizing the heating impact on the polyester mesh surrounding the heat sealing area. Simultaneously, the exhaust mechanism 5 is activated, its inlet connected to the sealed cavity inside the housing 1, to remove the solvent and other volatile substances volatilized from the PI film during the heat sealing process. After heat sealing is complete, the heating mechanism 2 is turned off, and the heating plate 22 is allowed to cool.

[0055] The technical effects of the above solution are as follows: By designing the equipment as a shell structure with a sealed containment cavity, and cooperating with the exhaust mechanism 5, it can effectively collect and remove harmful substances volatilized from the PI film during the heat sealing process. This greatly reduces the operator's contact with harmful volatile substances, lowers the risk of respiratory diseases, effectively protects the operator's nervous system and immune system, improves the working environment, and ensures the operator's health. Simultaneously, the cooling mechanism 3 introduces coolant into the first water-cooling channel 211 of the frame 21, allowing the frame 21 to absorb and remove some heat during heat sealing, preventing excessive heat from the heating plate 22 from being conducted to the periphery of the heat sealing area. The impact of heat on the periphery of the polyester mesh heat sealing area is significantly reduced, and its physical properties are maintained.

[0056] Preferably, referring to Figures 1-4, the heating mechanism 2 further includes a shelf 23, which is disposed within the housing 1. The shelf 23 has a groove 231, and the frame 21 is fixed within the groove 231. In this embodiment, the shelf 23 is disposed within the housing 1, and the frame 21 is fixed within the groove 231 of the shelf 23. This structural design provides a stable mounting foundation for the heating mechanism 2.

[0057] Preferably, referring to Figures 1-4, a second water-cooling channel 232 and a third water-cooling channel 233 are formed within the shelf 23. One end of the second water-cooling channel 232 is connected to one end of the first water-cooling channel 211, and one end of the third water-cooling channel 233 is connected to the other end of the first water-cooling channel 211. The cooling mechanism 3 includes a coolant tank 31, an inlet pump 32, an inlet pipe 33, an inlet valve 34, an outlet pipe 35, an outlet valve 36, and a cooling component 37. The coolant tank 31 is used to store coolant, and the inlet pump 32... The inlet of the pump is connected to the coolant tank 31, the outlet of the pump 32 is connected to one end of the inlet pipe 33, the other end of the inlet pipe 33 is connected to the other end of the second water-cooling channel 232, the inlet valve 34 is provided on the inlet pipe 33, one end of the outlet pipe 35 is connected to the other end of the third water-cooling channel 233, the other end of the outlet pipe 35 is connected to the coolant tank 31, the outlet valve 36 is provided on the outlet pipe 35, and the cooling component 37 is used to cool the coolant in the coolant tank 31.

[0058] In this embodiment, during use, the polyester mesh and metal mesh 6 are placed on the frame 21 and the upper surface of the heating plate 22 of the heating mechanism 2. At this time, the inlet pump 32 and inlet valve 34 are turned on. Under the action of the inlet pump 32, the coolant in the coolant tank 31 flows into the second water-cooling channel 232 in the shelf 23 through the inlet pipe 33. Since the second water-cooling channel 232 is connected to the first water-cooling channel 211 in the frame 21, the coolant then flows into the first water-cooling channel 211, preparing the heating mechanism 2 for cooling in advance and preventing residual heat from the heating plate 22 from affecting the subsequently placed mesh. Simultaneously, the cooling component 37 cools the coolant in the coolant tank 31, ensuring the coolant remains at a low temperature. The pressing mechanism 4 is activated to firmly press the polyester mesh and metal mesh 6 onto the upper surface of the heating plate 22. Then, the heating mechanism 2 is turned on, and the heating plate 22 begins to heat the area where the polyester mesh and metal mesh are connected, achieving heat sealing between the two. During the heating process, the coolant continuously circulates in the first water-cooling channel 211, the second water-cooling channel 232, and the third water-cooling channel 233, carrying away some of the heat generated by the heating plate 22, reducing the heat conducted from the heating plate 22 to the surrounding area, and minimizing the heating impact on the polyester mesh fabric surrounding the heat-sealing area. After flowing out of the third water-cooling channel 233, the coolant flows back to the coolant tank 31 through the outlet pipe 35, and the outlet valve 36 can control the flow of coolant.

[0059] In this embodiment, a complete coolant circulation system is formed by connecting the second water-cooling channel 232 and the third water-cooling channel 233 with the first water-cooling channel 211. This system can more efficiently remove the heat generated by the heating plate 22, effectively reducing the heating impact on the polyester mesh fabric surrounding the heat-sealing area and improving the heat-sealing quality. The cooling component 37 can cool the coolant in the coolant tank 31, ensuring that the coolant is always at a low temperature, thus making the cooling process more stable and controllable. The coolant circulates in the system, flowing out of the coolant tank 31, passing through each water-cooling channel, and then flowing back to the coolant tank 31, realizing the recycling of the coolant, reducing coolant waste, and lowering operating costs.

[0060] Preferably, as shown in Figures 1-4, in order to improve the space utilization within the housing 1, two shelves 23 are arranged side by side, and each shelf 23 is equipped with a heating mechanism 2. At the same time, the water cooling channels between two adjacent shelves 23 are connected by connecting pipes 24, so that the coolant can flow through the two shelves 23 and the heating mechanism 2 in sequence.

[0061] Preferably, referring to Figures 1-4, the cooling component 37 includes a temperature sensor 371 and a semiconductor cooling component 372. The temperature sensor 371 is disposed inside the coolant tank 31, the cold end of the semiconductor cooling component 372 is located inside the coolant tank 31, and the hot end of the semiconductor cooling component 372 is located outside the coolant tank 31. A stable coolant temperature is crucial for the normal operation of the high-safety wire mesh heat sealing equipment. Through the coordinated operation of the temperature sensor 371 and the semiconductor cooling component 372, large fluctuations in coolant temperature can be effectively avoided. This helps reduce damage to the heating mechanism and other components caused by temperature instability, extends the service life of the equipment, and improves the reliability and stability of the system.

[0062] Preferably, referring to Figures 1-4, the pressing mechanism 4 includes a pressing cylinder 41 and a pressure plate 42. The fixed end of the pressing cylinder 41 is fixed to the housing 1, and the output end of the pressing cylinder 41 is fixedly connected to the pressure plate 42. The pressure plate 42 is used to press the polyester mesh and metal mesh 6 placed on the heating plate 22. In this embodiment, the fixed end of the pressing cylinder 41 is fixed to the housing 1. This fixing method ensures that the pressing cylinder 41 has good stability during operation. When the cylinder is started, it can stably transmit force to the pressure plate 42, ensuring that the pressure plate 42 applies stable pressure to the polyester mesh and metal mesh 6, thereby ensuring the stability of the heat sealing quality.

[0063] Preferably, as shown in Figures 1-4, the housing 1 has an air inlet, a filter element 12 is installed inside the air inlet, and an exhaust port 13 is also installed on the housing 1. The exhaust mechanism 5 includes a suction hood 51, an exhaust fan 52, and a waste gas treatment device 53. The suction hood 51 is fixed above the pressure plate 42, and the outlet of the suction hood 51 is connected to the air inlet. The inlet of the exhaust fan 52 is connected to the air inlet, and the outlet of the exhaust fan 52 is connected to the inlet of the waste gas treatment device 53. In this embodiment, the filter element 12 installed inside the air inlet of the housing 1 can filter the air entering the housing. During the operation of the equipment, outside air enters through the air inlet, and the filter element 12 can intercept dust, particles, and other impurities in the air, preventing these impurities from entering the interior of the housing and avoiding their adhesion to components such as polyester mesh, metal mesh, or heating mechanisms, thereby ensuring the quality of the heat sealing process and reducing heat sealing defects caused by impurities. The exhaust system 5 removes solvents and other volatile substances emitted from the PI film during the heat sealing process. The suction hood 51, located above the pressure plate 42, efficiently collects these exhaust gases. The exhaust gases enter the exhaust fan 52 through the air inlet and are then transported to the exhaust gas treatment equipment 53. The exhaust gas treatment equipment 53 purifies the exhaust gases, removing harmful substances and ensuring that the emitted gases meet environmental standards, effectively improving workplace air quality and protecting the health of operators.

[0064] Preferably, referring to Figures 1-4, the high-safety mesh heat sealing equipment further includes several clamping mechanisms 7. Each clamping mechanism 7 includes a fixed post 71, a swing rod 72, a pressure rod 73, and a telescopic drive component 74. The fixed post 71 is fixed to the frame 21. The middle part of the swing rod 72 is hinged to the fixed post 71. One end of the pressure rod 73 is fixed to one end of the swing rod 72. One end of the telescopic drive component 74 is hinged to the fixed post 71, and the other end of the telescopic drive component 74 is hinged to the other end of the pressure rod 73. In this embodiment, after the polyester mesh and metal mesh 6 are placed on the heating plate 22, the clamping mechanism 7 can quickly pre-clamp their outer edges. Because the fixed post 71 is fixed to the frame 21, and the swing rod 72, pressure rod 73, and telescopic drive component 74 cooperate with each other, the mesh and metal mesh can be accurately positioned in a predetermined position. This ensures that they are in the correct initial position before the subsequent pressing mechanism 4 operates, avoiding poor heat sealing caused by positional deviations, such as uneven edges and loose fit, thus improving the accuracy of heat sealing and product quality.

[0065] The technical effects of the technical solution provided in Example 1 include:

[0066] 1. By designing the equipment with a sealed housing 1 and incorporating an exhaust system 5, harmful substances volatilized from the PI film during the heat-sealing process can be effectively collected and removed. This significantly reduces operator exposure to harmful volatiles, lowers the risk of respiratory illnesses, effectively protects the operator's nervous and immune systems, improves the working environment, and safeguards the operator's health. Simultaneously, the cooling system 3 introduces coolant into the first water-cooling channel 211 of the frame 21, allowing the frame 21 to absorb and remove some heat during heat sealing, preventing excessive heat from the heating plate 22 from being conducted to the periphery of the heat-sealing area. The impact of heat on the periphery of the polyester mesh heat-sealing area is greatly reduced, thus preserving its physical properties.

[0067] 2. After the polyester mesh and metal mesh 6 are placed on the heating plate 22, the clamping mechanism 7 can quickly pre-clamp their outer edges. Since the fixing post 71 is fixed to the frame 21, the swing rod 72, pressure rod 73, and telescopic drive component 74 cooperate to accurately position the mesh and metal mesh in the predetermined positions. This ensures they are in an accurate initial position before the subsequent clamping mechanism 4 operates, avoiding poor heat sealing due to positional deviations, such as uneven edges and loose adhesion, thus improving heat sealing accuracy and product quality.

[0068] Example 2

[0069] Referring to Figures 5 and 6, the main structure of Embodiment 2 is basically the same as that of Embodiment 1. The difference is that in Embodiment 2, the high-safety wire mesh heat sealing equipment further includes a flipping mechanism 8. The flipping mechanism 8 includes a rotating shaft 81 and a flipping drive component 82. The rotating shaft 81 is rotatably disposed within the housing 1 and extends horizontally. Two heating mechanisms 2 are respectively disposed on both sides of the rotating shaft 81. The shelves 23 of the two heating mechanisms 2 are respectively fixed to both sides of the rotating shaft 81. Each shelf 23 has a groove 231. A frame 21 is fixed in each groove 231. A heating plate 22 is installed in each frame 21. Several clamping mechanisms 7 are disposed on each frame 21. The flipping drive component 82 is connected to the rotating shaft 81 and is used to drive the rotating shaft 81 to rotate so that one of the shelves 23 is located above the rotating shaft 81. Specifically, the flipping drive component 82 is a flipping motor, which is connected to the rotating shaft 81. Its main function is to drive the rotating shaft 81 to rotate. This flipping motor uses a stepper motor, which rotates according to a specific pattern during operation: first, it rotates 180° clockwise, then 180° counterclockwise, then another 180° clockwise, and finally another 180° counterclockwise, and so on continuously. This cyclical rotation ensures the equipment achieves its required flipping function, guaranteeing smooth heat sealing. Furthermore, it avoids problems caused by excessive flipping, especially preventing situations where the cooling mechanism 3's piping length is insufficient for equipment operation. During equipment setup, the piping length design for the cooling mechanism 3 only needs to ensure sufficient spare length when the shaft 81 rotates 180° clockwise or counterclockwise. This design satisfies the requirements for normal equipment operation, optimizes piping usage, and improves the equipment's reliability and stability.

[0070] In this embodiment, during use, the operator opens the operating window 11 and places the polyester mesh and metal mesh 6 on the upper surface of the frame 21 and heating plate 22 of the heating mechanism 2 located above the rotating shaft 81. At this time, the clamping mechanism 7 corresponding to the heating mechanism 2 quickly pre-clamps the outer edges of the polyester mesh and metal mesh 6 to achieve positioning and fixation. The cooling mechanism 3 begins to introduce coolant into the first water-cooling channel 211 inside the frame 21 to prepare the heating mechanism 2 for cooling in advance, preventing residual heat from the heating plate 22 from affecting the mesh placed subsequently. The pressing mechanism 4 is activated to press the polyester mesh and metal mesh 6 tightly onto the upper surface of the heating plate 22. The heating mechanism 2 is turned on, and the heating plate 22 begins to heat the connection area between the metal mesh and the polyester mesh, achieving heat sealing between the two. During this process, because the frame 21 has the first water-cooling channel 211, it carries away some heat, reducing the heat conducted by the heating plate 22 to the surrounding area and reducing the heating impact on the polyester mesh outside the heat-sealing area. Simultaneously, the exhaust mechanism 5 is activated, its inlet connecting to the sealed cavity inside the housing 1, to remove the solvent and other volatile substances volatilized from the PI film during the heat sealing process. Once the upper heating mechanism 2 completes the heat sealing, it is shut off. Then, the flipping drive 82 is activated, driving the rotating shaft 81 to rotate, causing the shelf 23 of the heat-sealed heating mechanism 2 to rotate below the rotating shaft 81. When the shelf 23 rotates below the rotating shaft 81, the corresponding clamping mechanisms 7 of the heating mechanism 2 release, and the polyester mesh and metal mesh 6 automatically fall below under gravity. Simultaneously, the shelf 23 of another unused heating mechanism 2 rotates above the rotating shaft 81. New polyester mesh and metal mesh 6 to be heat-sealed are placed on the frame 21 and heating plate 22 of the heating mechanism 2 located above the rotating shaft 81, and the above preparation, heat sealing, and flipping stages are repeated to achieve continuous screen heat sealing. The staff only needs to place the new polyester mesh and metal mesh 6 to be heat-sealed on the upper surface of the frame 21 and heating plate 22 of the heating mechanism 2 located above the rotating shaft 81, and collect the heat-sealed polyester mesh and metal mesh 6 that fall below at intervals.

[0071] In this embodiment, a dual heating mechanism 2 is used, which is switched between the two heating mechanisms via a flipping mechanism 8. While one heating mechanism 2 is performing heat sealing, the other heating mechanism 2 can be left to cool down naturally, reducing equipment downtime, enabling continuous production, and greatly improving production efficiency. If there were only one heating mechanism 2, it would be necessary to wait for it to cool down after heat sealing before placing the next polyester mesh and metal mesh 6. Therefore, using a dual heating mechanism 2 reduces equipment downtime and enables continuous production. Simultaneously, after heat sealing, the clamping mechanism 7 releases, allowing the heat-sealed polyester mesh and metal mesh 6 to fall off automatically, eliminating the need for manual removal and further saving operation time and improving production continuity. Furthermore, the flipping mechanism 8 allows the two heating mechanisms 2 to work alternately within a limited space, fully utilizing the space within the housing 1, making the equipment structure more compact and reducing its footprint.

[0072] Preferably, referring to Figures 5 and 6, the flipping mechanism 8 further includes a positioning component 83. The positioning component 83 includes two positioning cylinders 831 and a positioning telescopic member 832. The two positioning cylinders 831 are respectively fixed to two opposite frame bodies 21. The fixed end of the positioning telescopic member 832 is fixed to the housing 1. When one of the shelves 23 is located above the rotating shaft 81 and is horizontally positioned, the movable end of the positioning telescopic member 832 can be inserted into the positioning cylinder 831 fixed on the shelf 23. In this embodiment, when the flipping drive 82 drives the rotating shaft 81 to rotate, causing one of the shelves 23 to be located above the rotating shaft 81 and horizontally positioned, the movable end of the positioning telescopic member 832 is inserted into the positioning cylinder 831 fixed on the shelf 23. This precise fit ensures that the heating mechanism 2 is in an accurate working position, guaranteeing the positional accuracy of the polyester mesh and metal mesh 6 during the heat sealing process.

[0073] Preferably, referring to Figures 5 and 6, a collection plate 14 is also provided inside the housing 1, located below the shelf 23. When the flipping mechanism 8 rotates the heating mechanism 2, which has completed heat sealing, below the rotating shaft 81, and the clamping mechanism 7 is released, the polyester mesh and metal mesh 6 will fall onto the collection plate 14 under gravity. The collection plate 14 provides a centralized collection area, allowing the heat-sealed products to be stacked in an orderly manner. Workers only need to collect the products from the collection plate 14 periodically, greatly improving the efficiency of product collection.

[0074] The technical effects of the technical solution provided in Example 2 include:

[0075] 1. The system employs dual heating mechanisms 2, which are switched via a flipping mechanism 8. While one heating mechanism 2 is performing heat sealing, the other heating mechanism 2 can be left to cool down naturally, reducing equipment downtime, enabling continuous production, and significantly improving production efficiency. The flipping mechanism 8 allows the two heating mechanisms 2 to work alternately within a limited space, making full use of the space inside the housing 1, resulting in a more compact structure and reduced floor space.

[0076] 2. When the flipping drive 82 drives the rotating shaft 81 to rotate, so that one of the shelves 23 is positioned above the rotating shaft 81 and horizontally, the movable end of the positioning telescopic component 832 is inserted into the positioning cylinder 831 fixed on the shelf 23. This precise fit ensures that the heating mechanism 2 is in the accurate working position, guaranteeing the positional accuracy of the polyester mesh and metal mesh 6 during the heat sealing process.

[0077] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of this application.
