Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminized film production, and in particular to an aluminized film straightening and drying machine. Background Technology
[0002] Metallized film is a composite material in which a nanoscale aluminum layer is deposited on the surface of a plastic film through vacuum evaporation technology. It combines the flexibility of plastic with the functionality of metal and is widely used in packaging, electronics, new energy and other fields. The straightening and drying of metallized film refers to the use of a hot air circulation system to accelerate the drying process. By controlling the temperature and wind speed, the solvent is effectively removed to ensure that the metallized film remains flat and stable during the drying stage, avoiding problems such as wrinkles, displacement or uneven aluminum layer caused by thermal stress or airflow disturbance.
[0003] For example, patent document CN223036802U discloses a straightening and drying device for aluminized film processing, relating to the field of aluminized film processing technology. This utility model includes a drying chamber with an inlet on one side and an outlet on the other. Positioning rollers are fixed inside both the inlet and outlet. Several heating rollers are fixed to one side of the inner wall of the drying chamber, and several ventilation holes are opened on the surface of the heating rollers. The heating rollers are hollow cylindrical structures. An air inlet is opened at the rear of the drying chamber, communicating with the heating rollers. This device uses the action of the heating rollers to pull the mounting plate out of the mounting groove, thereby allowing for the maintenance or replacement of the heating wire or filter screen. This ensures the heating and cleaning effect of the device on the air entering the drying chamber. The cross-arranged limiting rollers and heating rollers keep the aluminized film unfolded during the air-drying process, preventing folding due to inadequate straightening, thus improving the drying efficiency of the device.
[0004] In existing technologies, three temperature gradients are typically set up inside the drying chamber: a preheating section, a main drying section, and a cooling section. This requires a complex temperature control system to ensure temperature stability in each section. However, the construction and operating costs of such a system are high, which hinders the widespread adoption of the equipment. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.
[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] like Figures 1-7As shown, an aluminized film straightening dryer includes a main body, which includes a closed support 102. An air extraction mechanism is installed at the top of the closed support 102. Several fixed support rollers 105 are rotatably connected to bearings inside the closed support 102. A blower mechanism is installed on the closed support 102, and the blower mechanism includes several fan-shaped air outlet boxes 201 rotatably connected to the bearings of the closed support 102. The fixed support rollers 105 and the fan-shaped air outlet boxes 201 are connected by a swing assembly. The front side of the fan-shaped air outlet boxes 201 is sealed. A temperature control box 205 is dynamically connected, and a temperature control mechanism is installed on the temperature control box 205. The temperature control mechanism includes a temperature sensing ring 301 bolted to the front end of the temperature control box 205, the temperature sensing ring 301 being filled with a thermal expansion material, a piston rod 302 being slidably and sealingly connected to the lower end of the temperature sensing ring 301, a venturi tube 304 being sealed and fixedly connected to the rear end of the temperature control box 205, a high-temperature air inlet pipe 206 being sealed and fixedly connected to the rear side of the venturi tube 304, and a normal-temperature air inlet pipe 305 being fixedly connected to the lower end of the narrow neck of the venturi tube 304. A rotary valve 306 is installed on the ambient temperature air inlet pipe 305. The piston rod 302 drives the rotary valve 306 to rotate through the lever assembly. In use, high-temperature air enters the temperature control box 205 from the high-temperature air inlet pipe 206. The temperature sensing ring 301 senses the temperature change, and the thermal expansion material inside the temperature sensing ring 301 expands and pushes the piston rod 302 out. The displacement of the piston rod 302 is amplified by the lever assembly, which drives the rotary valve 306 to open. Since the hot air flows through the venturi tube 304, the pressure at the narrow neck of the venturi tube 304 is relatively small, so ambient temperature air can enter the temperature control box 205 from the ambient temperature air inlet pipe 305. The hot air mixes with the ambient temperature air, so the airflow temperature decreases. The piston rod 302 can be dynamically adjusted under the action of the thermal expansion material, thereby realizing the dynamic adjustment of the rotary valve 306, and finally stabilizing the airflow temperature within a certain range. In this way, the temperature can be automatically regulated by the thermal expansion material without the need for external active influence. Moreover, the structure is simple, the manufacturing and use costs are reduced, and the device is easy to promote.
[0030] The lever assembly includes an amplifying lever 303 rotatably connected to the bottom of the temperature control box 205. The amplifying lever 303 has straight grooves at both ends. The straight groove at the short end of the amplifying lever 303 is hinged to the piston rod 302. A fixed connecting rod 307 is fixedly connected to the outside of the valve core of the rotary valve 306. Furthermore, the fixed connecting rod 307 is a telescopic structure (not shown in the diagram), capable of adjusting its length. This structure is widely used in existing technologies and will not be elaborated upon here. The straight groove at the long end of the amplifying lever 303 is hinged to the fixed connecting rod 307. In use, the piston rod 302 moves, pushing the amplifying lever 303 to rotate. The other end of the amplifying lever 303 pushes the fixed connecting rod 307 to rotate, causing the rotary valve 306 to open.
[0031] The main body of the device also includes a base 101, a closed bracket 102 fixedly connected to the top of the base 101, an inlet roller 104 rotatably connected to one side of the closed bracket 102, an outlet roller 103 rotatably connected to the other side of the closed bracket 102, and several fixed support rollers 105 connected to a synchronous belt via synchronous pulleys. A power motor 106 is fixedly connected to the outside of the closed bracket 102, and the output end of the power motor 106 is fixedly connected to one of the fixed support rollers 105. In use, the operator feeds the aluminized film into the device from the inlet roller 104, and then it passes through multiple fixed support rollers 105 and tension support rollers 110 before leaving the device from the outlet roller 103. The power motor 106 drives the fixed support rollers 105 connected to it to rotate, and the fixed support rollers 105 drive other fixed support rollers 105 to rotate via synchronous belts and synchronous pulleys, so the aluminized film moves continuously.
[0032] The swing assembly includes a first crank 202 fixedly connected to the front end of the fan-shaped air outlet box 201, a second crank 204 fixedly connected to the front end of the fixed support roller 105, and a rocker arm 203 hinged between the first crank 202 and the second crank 204. The first crank 202 is longer than the second crank 204. In use, the fixed support roller 105 rotates, causing the second crank 204 to rotate. The second crank 204 drives the rocker arm 203 to swing, and the rocker arm 203 drives the first crank 202 to swing. The first crank 202 drives the fan-shaped air outlet box 201 to swing. The reciprocating swing of the fan-shaped air outlet box 201 can make the blown hot air uniform and avoid uneven heating.
[0033] A lifting frame 108 is slidably connected to the lower end of the enclosed bracket 102. Several bearing seats 109 are slidably connected to the lifting frame 108. A spring 111 is fixedly connected between the bearing seats 109 and the lifting frame 108. A tensioning support roller 110 is hinged between two corresponding bearing seats 109. A cylinder 107 is fixedly connected to the bottom of the enclosed bracket 102. The output end of the cylinder 107 is fixedly connected to the lifting frame 108. In use, the cylinder 107 drives the lifting frame 108 to rise and fall. The lifting frame 108 drives the bearing seats 109 to rise and fall. The bearing seats 109 drive the tensioning support roller 110 to rise and fall. The tensioning support roller 110 descends to tension the aluminized film. The spring 111 ensures that the tensioning support roller 110 has a certain elastic buffer.
[0034] The other end of the high-temperature air inlet pipe 206 is fixedly connected to an air distribution box 207. An electric heating wire assembly 209 is fixedly connected to the upper part of the air distribution box 207. A blower 208 is fixedly connected to the side of the air distribution box 207. A normal-temperature air box 308 is fixedly connected to the rear side of the air distribution box 207. The normal-temperature air inlet pipe 305 is connected to the normal-temperature air box 308. Several staggered baffles 309 are fixedly connected inside the temperature control box 205. During use, the blower 208 forces air... The air enters the air distribution box 207, and then most of the air is heated by the heating wire assembly 209 before entering the high-temperature air inlet pipe 206. It then enters the temperature control box 205 through the high-temperature air inlet pipe 206. The lower part of the air enters the ambient temperature air box 308, and then enters the venturi tube 304 through the ambient temperature air inlet pipe 305. Finally, the ambient temperature airflow and the high-temperature airflow are mixed in the temperature control box 205. The baffle plate 309 is set to ensure that the two gases at different temperatures are fully mixed.
[0035] The air extraction mechanism includes a main pipe 401 fixedly connected to the top of the enclosed bracket 102. One end of the main pipe 401 is fixedly connected to an air pump 402, and the air pump 402 is externally connected to a condenser. Several L-shaped branch pipes 403 are fixedly connected to the main pipe 401. The other end of the branch pipes 403 extends into the enclosed bracket 102. When in use, the air pump 402 starts to generate negative pressure, so the branch pipes 403 draw away the air with increased humidity to prevent condensation in the enclosed bracket 102. The humid air enters the main pipe 401 from the branch pipes 403 and finally enters the external condenser under the action of the air pump 402.
[0036] Working principle: The operator feeds the aluminized film into the device through the inlet roller 104, then winds it through multiple fixed support rollers 105 and tension support rollers 110 before exiting the device through the outlet roller 103. Cylinder 107 drives the lifting frame 108 to rise and fall, which in turn drives the bearing seat 109 to rise and fall. The bearing seat 109 then drives the tension support rollers 110 to rise and fall. The tension support rollers 110 descend to tension the aluminized film. The power motor 106 drives the connected fixed support rollers 105 to rotate. The support roller 105 drives other fixed support rollers 105 to rotate via a synchronous belt and synchronous pulley, thus causing the aluminum-coated film to move continuously. The rotation of the fixed support rollers 105 drives the second crank 204 to rotate, which in turn drives the rocker arm 203 to swing. The rocker arm 203 then drives the first crank 202 to rock, which in turn drives the fan-shaped air outlet box 201 to rock. In use, the blower 208 blows air into the air distribution box 207, and then most of the air is heated by the heating wire assembly 209 before entering the high-temperature air intake. The air enters the temperature control chamber 205 through the high-temperature inlet pipe 206, and the lower part of the air enters the ambient temperature chamber 308. The high-temperature air enters the temperature control chamber 205 through the high-temperature inlet pipe 206. The temperature sensing ring 301 senses the temperature change, and the thermal expansion material inside the temperature sensing ring 301 expands and pushes the piston rod 302 to extend. The displacement of the piston rod 302 is amplified by the lever assembly, which can drive the rotary valve 306 to open. Since the hot air flows through the venturi tube 304, the pressure at the narrow neck of the venturi tube 304 is relatively small, so ambient temperature air can enter the temperature control chamber 205 through the ambient temperature inlet pipe 305. The hot air mixes with the ambient temperature air, so the airflow temperature decreases. The piston rod 302 can be dynamically adjusted under the action of the thermal expansion material, thereby realizing the dynamic adjustment of the rotary valve 306, and finally realizing the stabilization of the airflow temperature within a certain range. In this way, the temperature can be automatically regulated by the thermal expansion material without the need for external active influence. Moreover, the structure is simple, the manufacturing and use costs are reduced, and the device is easy to promote.
[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
