[0015] The beneficial effects of the present invention are as follows: the high-efficiency and energy-saving film blowing machine described in the present invention transports gas to the air storage chamber through the air inlet pipe, and then effectively exchanges the heat of the water in the water storage chamber through the heat exchange plate, thereby reducing the water temperature in the water storage chamber and enhancing the cooling effect. In this process, the water in the water storage chamber can absorb the heat from the air storage chamber after contacting the heat exchange plate, thereby achieving the reduction of water temperature, and maintaining the thermal balance of the system to prevent the negative impact of excessive water temperature on the cooling efficiency. The cooling gas after heat exchange will be guided to the water spray chamber through the connecting pipe, thereby significantly improving the gas pressure in the water spray chamber. The increase in gas pressure enables water to be sprayed out through the nozzle at a higher speed and with a stronger impact force, further enhancing the cooling effect. The sprayed water mist or water flow can quickly reduce the temperature of the film bubble when in contact with the film bubble, accelerate the cooling process of the film bubble, and thereby ensure the molding quality and production efficiency of the film.

[0016] The high-efficiency and energy-saving film blowing machine described in the present invention starts a vibration motor, which will generate a vibration of a certain frequency, so that the vibration motor drives the filter plate to vibrate up and down. The vibration of the filter plate causes the first sliding frame and the second sliding frame to slide up and down in the sliding groove of the feed frame, thereby increasing the movement frequency and strength of the sliding frame, further accelerating the filtering speed of the filter plate, and improving the filtering efficiency. In the process of the filter plate vibrating up and down, the vibration causes the connecting block and the pressure block to be linked, thereby driving the pressure block to move up and down. The pressure block that moves up and down will continuously hit the elastic airbag, generating a certain impact force, thereby promoting the elastic deformation and recovery of the airbag.

[0017] The high-efficiency and energy-saving film blowing machine described in the present invention passes the formed film from the forming area through the limiting roller mechanism. The function of the limiting roller mechanism is to ensure the stability of the film path and prevent the film from being offset or wrinkled during the winding process. Subsequently, the formed film is guided and wound onto the winding roller. Next, by starting the drive motor, the drive motor drives the rotation of the winding roller so that the film is evenly wound on the winding roller. The drive motor transmits power to the second pulley through the transmission system using the first pulley mechanism, so that the second pulley drives the limiting roller to rotate. The rotation of the limiting roller plays a key role. By controlling the movement speed and path of the film, it is ensured that the film always remains on the correct track during the winding process to avoid stretching or twisting of the film. This mechanism can accurately limit the moving direction of the formed film and ensure that the winding process is stable and smooth. At the same time, the working principle of the limiting roller makes the winding process more efficient, and the formed film can be quickly and evenly wound onto the winding roller, which provides convenience for subsequent film processing or packaging.

[0021] Embodiment 1 like Figures 1 to 7 As shown, an efficient and energy-saving film blowing machine according to an embodiment of the present invention, please refer to Figure 1 , Figure 2, including a frame 100, a heating mechanism 200 is fixedly connected to the upper end of the frame 100, an extrusion tube 130 is fixedly connected to one side of the heating mechanism 200, a heating ring 110 is fixedly connected to the outer side of the extrusion tube 130, a feeding mechanism 300 is fixedly connected to the upper end of the heating mechanism 200, an extrusion mechanism 120 is fixedly connected to one side of the extrusion tube 130, a cooling mechanism 600 is fixedly connected to the outer side of the extrusion mechanism 120, a control panel 900 is fixedly connected to the inclined surface of the upper end of the frame 100, a mounting plate 700 is fixedly connected to one side of the frame 100, and a molding mechanism 800 is fixedly connected to the side of the mounting plate 700 facing the heating mechanism 200.

[0022] Specifically, first, the heating mechanism 200 is controlled by the control panel 900 to heat. When heated to the set temperature, it is switched to the insulation mode. Then, the raw material is transported to the heating mechanism 200 through the feeding mechanism 300 for heating. Then, the film is extruded through the extrusion mechanism 120. The film is cooled by the cooling mechanism 600. Finally, the film is pulled and rolled up by the forming mechanism 800. In this way, the raw material can be quickly made into a film.

[0023] Please refer to Figure 3 , Figure 4 The upper end of the heating mechanism 200 is fixedly connected to a feeding mechanism 300, and the feeding mechanism 300 includes a feeding frame 301 fixedly connected to the upper end of the heating mechanism 200, a placement groove 302 is provided on one side of the feeding frame 301, and sliding grooves 303 are provided on the upper and lower sides of the placement groove 302.

[0024] Specifically, by starting the vibration motor 404, the vibration motor 404 will generate a certain frequency of vibration, so that the vibration motor 404 drives the filter plate 401 to vibrate up and down. The vibration of the filter plate 401 causes the first sliding frame 402 and the second sliding frame 403 to slide up and down in the sliding groove 303 of the feed frame 301, thereby increasing the movement frequency and strength of the sliding frame, further accelerating the filtering speed of the filter plate 401, and improving the filtering efficiency. In the process of the filter plate 401 vibrating up and down, the vibration causes the connecting block 405 to be linked with the pressure block 406, thereby driving the pressure block 406 to move up and down. The pressure block 406 that moves up and down will continuously hit the elastic airbag 501, generating a certain impact force, thereby promoting the elastic deformation and recovery of the elastic airbag 501.

[0025] Please refer to Figure 5 , Figure 6 The upper end of the frame 100 is fixedly connected to an air intake mechanism 500, and the air intake mechanism 500 includes an elastic air bag 501 fixedly connected to the upper end of the heating mechanism 200, one side of the elastic air bag 501 is fixedly connected to an air intake pipe 504, and the outer side of the air intake pipe 504 is fixedly connected to a second one-way valve 505, the left side of the elastic air bag 501 is fixedly connected to an air outlet pipe 502, and the outer side of the air outlet pipe 502 is fixedly connected to a first one-way valve 503, and the cooling mechanism 600 includes a cooling ring 602 fixedly connected to the outer side of the extrusion mechanism 120, and an air storage cavity 603 is opened inside the cooling ring 602, and the outer wall of the air storage cavity 603 is fixedly connected to a transport pipe 604, the other end of the air transport pipe 604 is fixedly connected to the air outlet pipe 502, a water storage chamber 608 is provided inside the cooling circle 602, the outer wall of the water storage chamber 608 is fixedly connected to the water inlet pipe 605, the outer side of the water inlet pipe 605 is fixedly connected to the solenoid valve 606, the air storage chamber 603 and the water storage chamber 608 are separated by a heat exchange plate 607, a water spray chamber 609 is provided inside the cooling circle 602, the outer wall of the water spray chamber 609 is fixedly connected to a plurality of nozzles 610, the outer side of the cooling circle 602 is fixedly connected to a connecting pipe 601, one end of the connecting pipe 601 is located in the air storage chamber 603, and the other end of the connecting pipe 601 is located in the water spray chamber 609.

[0026] Specifically, when the pressure block 406 strikes the elastic airbag 501, the elastic airbag 501 will discharge gas from the air outlet pipe 502 to the air supply pipe 604, and the gas will be transported to the air storage chamber 603 through the air supply pipe 604. In addition, the external gas can be transported into the elastic airbag 501 through the air inlet pipe 504, and then the heat of the water in the water storage chamber 608 is effectively exchanged through the heat exchange plate 607, so that the water temperature in the water storage chamber 608 is reduced and the cooling effect is enhanced. In this process, the water in the water storage chamber 608 can absorb the heat from the air storage chamber 608 after contacting the heat exchange plate 607. 03's heat can be absorbed, thereby lowering the water temperature and maintaining the thermal balance of the system to prevent excessive water temperature from having a negative impact on the cooling efficiency. The cooling gas after heat exchange will be guided to the water spray chamber 609 through the connecting pipe 601, thereby significantly improving the gas pressure in the water spray chamber 609. The increase in gas pressure allows water to be sprayed out through the nozzle 610 at a higher speed and with a stronger impact force, further enhancing the cooling effect. The sprayed water mist or water flow can quickly lower the temperature of the bubble when it comes into contact with the bubble, accelerate the cooling process of the bubble, and thereby ensure the molding quality and production efficiency of the film.

[0027] Please refer to Figure 7 The forming mechanism 800 includes a fixed plate 801 fixedly connected to both sides of the mounting plate 700, one side of the fixed plate 801 is fixedly connected to a support plate 802, the upper end of the support plate 802 is fixedly connected to a driving motor 803, the output end of the driving motor 803 is sleeved with a first pulley mechanism 804, the output end of the driving motor 803 passes through the fixed plate 801 and is fixedly connected to a winding roller 808, the output end of the driving motor 803 is rotatably connected to the fixed plate 801, the winding roller 808 is rotatably connected to the inner wall of the fixed plate 801, the outer side of the fixed plate 801 is fixedly connected to a limiting plate 805, the inner wall of the limiting plate 805 is rotatably connected to a second pulley mechanism 806, the second pulley mechanism 806 is fixedly connected to a limiting roller mechanism 807, the limiting roller mechanism 807 is rotatably connected to the inner wall of the fixed plate 801, and the second pulley mechanism 806 is fixedly rotatably connected to the first pulley mechanism 804.

[0028] Specifically, the formed film is passed through the limiting roller mechanism 807 from the forming area. The function of the limiting roller mechanism 807 is to ensure the stability of the film path and prevent the film from being offset or wrinkled during the winding process. Subsequently, the formed film is guided and wound onto the winding roller 808. Next, by starting the drive motor 803, the drive motor 803 drives the winding roller 808 to rotate, so that the film is evenly wound on the winding roller 808. The drive motor 803 transmits power to the second pulley mechanism 806 through the transmission system using the first pulley mechanism 804 (the pulley mechanism is composed of a belt and a driven wheel), thereby causing the second pulley mechanism 806 to drive the limiting roller to rotate. The rotation of the limiting roller plays a key role. By controlling the movement speed and path of the film, it is ensured that the film always remains on the correct track during the winding process to avoid stretching or twisting of the film. This mechanism can accurately limit the moving direction of the formed film and ensure that the winding process is stable and smooth. At the same time, the working principle of the limiting roller makes the winding process more efficient, and the formed film can be quickly and evenly wound onto the winding roller 808, providing convenience for subsequent film processing or packaging.

[0029] How it works In the initial state, the heating coil 110 and the heating mechanism 200 are controlled by the control panel 900 to heat. When heated to the set temperature, it is switched to the insulation mode, and then the raw materials are transported to the heating mechanism 200 through the feed frame 301, so as to heat the raw materials, and at the same time, the vibration motor 404 is started, so that the vibration motor 404 drives the filter plate 401 to vibrate up and down. The vibration of the filter plate 401 makes the first sliding frame 402 and the second sliding frame 403 slide up and down in the sliding groove 303 of the feed frame 301, thereby accelerating the filtration speed of the filter plate 401, and causing the connecting block 405 to be linked with the pressure block 406, thereby driving the pressure block 406 to move up and down. The pressure block 406 that moves up and down will continuously hit the elastic airbag 501. When the pressure block 406 hits the elastic airbag 501, the elastic airbag 501 will discharge the gas from the outlet pipe 502 to The air delivery pipe 604 is used to transport the gas to the air storage chamber 603, and the external gas can be transported to the elastic airbag 501 through the air inlet pipe 504, and then the heat of the water in the water storage chamber 608 is effectively exchanged through the heat exchange plate 607, so that the water temperature in the water storage chamber 608 is reduced, and then the film bubble extruded by the extrusion mechanism 120 is cooled, so that the cooling effect is enhanced. The cooling gas after heat exchange will be guided to the water spray chamber 609 through the connecting pipe 601, thereby significantly increasing the gas pressure in the water spray chamber 609. The increase in gas pressure enables water to be sprayed out through the nozzle 610 at a higher speed and stronger impact force, further enhancing the cooling effect, and passing the formed film from the forming area through the limiting roller mechanism 807. The function of the limiting roller mechanism 807 is to ensure the stability of the film path and prevent the film from being offset or wrinkled during the winding process. Subsequently, the formed film is guided and wound onto the winding roller 808. Next, by starting the driving motor 803, the driving motor 803 drives the winding roller 808 to rotate, so that the film is evenly wound on the winding roller 808. The driving motor 803 transmits power to the second pulley mechanism 806 through the transmission system using the first pulley mechanism 804, so that the second pulley mechanism 806 drives the limiting roller to rotate. The rotation of the limiting roller plays a key role. By controlling the movement speed and path of the film, it is ensured that the film always stays on the correct track during the winding process, avoiding the stretching or distortion of the film, and the formed film can be quickly and evenly wound on the winding roller 808, which provides convenience for subsequent film processing or packaging.
