[0002] In the film manufacturing industry, the transmission and winding of the film is one of the key links, and its accuracy and stability directly affect the quality of the final product. Traditional film conveying mechanisms often lack an efficient correction mechanism, resulting in the film easily deviating from the preset track due to various factors (such as uneven tension, guide wheel wear, etc.) during long-term and high-speed transmission, which in turn causes problems such as winding misalignment and wrinkles, which not only affects the aesthetics and practicality of the product, but also increases the difficulty and cost of subsequent processing. In order to solve this technical problem, the market urgently needs a conveying mechanism that can monitor and automatically adjust the film transmission position in real time to ensure the stability and accuracy of the film during the transmission process. It is in this context that the present application is proposed, and aims to provide a film conveying mechanism with an efficient correction function through innovative design to meet the film manufacturing industry's demand for high-quality and high-efficiency production.

[0027] See also Figures 1 to 5The present invention provides a film conveying mechanism 100, comprising a support 10, a roller 20, a contact sensor 60, and a deviation correction assembly 70. The support 10 comprises a support column and two parallel beams 12, which are mounted on the support 10. The roller 20 is mounted on each of the two beams 12 at both ends. Multiple rollers 20 are arranged along the film conveying path, and are used to convey the extruded film. The contact sensor 60 is mounted on the beam 12 and is used to detect whether the wound film deviates from a preset track. The correction component 70 includes a rotating shaft 71, a sleeve 72, an adjusting stop 73 and a telescopic motor 74. The rotating shaft 71 is installed on the bracket 10, the sleeve 72 is rotatably sleeved on the rotating shaft 71, the adjusting stop 73 is sleeved on the rotating shaft 71 and can slide along the length direction of the rotating shaft 71, the adjusting stop 73 slides to block both sides of the width direction of the film to adjust the position of the film in the length direction of the rotating shaft 71; the adjusting stop 73 is provided at both ends of the sleeve 72, and the two telescopic motors 74 are respectively installed on the two beams 12, and the output shaft of the telescopic motor 74 is connected to the adjusting stop 73. The telescopic motor 74 is used to drive the output shaft to extend or retract according to the signal of the contact sensor 60, adjust the position of the adjusting stop 73 in the length direction of the rotating shaft 71, so as to adjust the position of the film in the length direction of the roller 20.

[0028] The film conveying mechanism 100 of the present application realizes precise control and adjustment of the position of the film during the transmission process of the rolled film by innovatively setting up the correction component 70, thereby significantly improving production efficiency and product quality. Specific beneficial effects include: First, the mechanism can monitor the position status of the film during the transmission process in real time. Once it detects deviation from the preset track, it immediately makes rapid adjustments through the contact sensor 60 and the correction component 70, effectively avoiding the problems of misalignment and wrinkles when the film is rolled up, and ensuring the flatness and consistency of the film. Secondly, the design of the correction component 70 is flexible and efficient. Through the precise drive of the telescopic motor 74, it can achieve fine-tuning of the position of the adjustment block 73, ensuring that the film always maintains the correct position in the length direction of the roller 20, and improving the stability and reliability of the automated production line. Finally, the application of this mechanism also reduces the need for manual intervention, reduces production costs and labor intensity, and provides an intelligent and efficient solution for the film manufacturing industry, promoting an overall improvement in production efficiency.

[0029] Specifically, please combine Figure 1 and Figure 2 A film conveying mechanism 100 of the present application includes a bracket 10, a roller 20, a water cooling system 30, an air cooling system 40, a strong air pipe 50, a contact sensor 60 and a correction component 70.

[0030] The support 10 includes two pillars 11, a crossbeam 12, and an extension frame 13. The crossbeam 12 has two parallel and spaced apart arrangements. Multiple pillars 11 are provided under the crossbeam 12 to support the crossbeam 12. The number of pillars 11 can be adjusted as needed. The roller 20 is installed at both ends in the gap between the two crossbeams 12. The roller 20 is arranged perpendicular to the crossbeam 12 and extends along the direction of the film transmission path ( Figure 1 A plurality of parallel rollers 20 are disposed on the crossbeam 12 (in the direction indicated by the straight arrows). The rollers 20 are used to transport the extruded film. An extension frame 13 is mounted on the crossbeam 12. The extension frame 13 is equipped with rollers 20. The extension frame 13 is used to change the flow path of the film, or in other words, the flow path of the film passes through the rollers 20 on the extension frame 13. Specifically, the extension frame 13 includes two sets of parallel connecting rods, one end of which is fixed to the crossbeam 12 and the other end extends downward. The rollers 20 are mounted on the two parallel connecting rods and are located at the end of the connecting rods away from the crossbeam 12. During transport, the film passes under the lower surface of the rollers 20. Along the film transport path, the last roller 20 is used to reel up the film. This roller 20 is connected to a drive mechanism (not shown), which drives the roller 20 to rotate and reel up the film.

[0031] Please refer to Figure 1 The water cooling system 30 includes a water tank 31, a heat dissipation pipe 32, and a water pump 33. The water tank 31 is used to cool the film, while the heat dissipation pipe 32 uses the heat dissipated by the water to dehumidify the cooled film. Specifically, the extension frame 13 extends into the water tank 31, allowing the film to pass through the water tank 31. In other words, the water tank 31 is located below the extension frame 13.

[0032] The water inlet of the heat dissipation water pipe 32 is connected to the water pump 33, and the water at the water outlet of the heat dissipation water pipe 32 flows back to the water tank 31 through the pipe. Specifically, the heat dissipation water pipe 32 includes multiple parallel and spaced water pipes 321. The water inlet of the first water pipe 321 is connected to the water pump 33 through the pipe, and the water outlet of the last water pipe 321 draws water into the discrete hot water pipe 32 and returns it to the water tank 31 through the pipe, realizing water recycling. Two adjacent water pipes 321 are connected end to end along the direction of water flow. Along the direction of the film transmission path, the heat dissipation water pipe 32 is located downstream of the heat dissipation water pipe 32 and is provided with heat dissipation air pipes 42 on both sides of the film flow path. The heat dissipation air pipes 42 are used to dehumidify and dry the upper and lower sides of the film.

[0033] The water pump 33 is used to pump water out of the water tank 31 and pass it through the heat dissipation water pipe 32. Specifically, the water pump 33 is installed on the ground or on the bracket 10. It can be set as needed. The water pump 33 is connected to the water tank 31 through a pipe to pump water to the water guide pipe 321, and finally returns it to the water tank 31.

[0034] When the film passes through the water tank 31, the cooling water in the water tank 31 becomes hot. The heat dissipation water pipe 32 uses the heat to dehumidify and dry the surface of the film. The extracted water dissipates heat through the heat dissipation water pipe 32 and the pipeline. The water after heat dissipation flows back to the water tank 31 to cool the water tank 31 and realize water circulation.

[0035] Please refer to Figure 1 The air cooling system 40 includes a heat storage tank 41, a heat dissipation pipe 42 and a fan 43. The flow path of the film passes through the heat storage tank 41, which is used to collect hot air generated by the heat dissipated by the film just after it is formed; the two ends of the heat dissipation pipe 42 are installed on two parallel beams 12. The heat dissipation pipe 42 is close to the flow path of the film. The heat dissipation pipe 42 is used to dehumidify the film after water cooling by using the heat dissipation. The fan 43 is used to extract the hot air from the heat storage tank 41 and pass it through the heat dissipation pipe 42.

[0036] Along the film's transport path, heat dissipation pipes 42 are located between the heat dissipation pipes 32 and the water reservoir 31. Heat dissipation pipes 42 are located above and below the film's path. These pipes dehumidify both sides of the film. After cooling the film in the water reservoir 31, it first passes through the heat dissipation pipes 42 and then returns to the heat dissipation pipes 42.

[0037] The thermal storage tank 41 consists of two upper and lower boxes, located on either side of the film. After being formed and produced, the film first passes through the thermal storage tank 41. The heat dissipation pipe 42 comprises multiple parallel, spaced-apart air ducts. The air inlet of the first air duct is connected to a fan 43 via a pipe, and the water outlet of the last air duct pumps water away from the heat dissipation pipe 42. Adjacent air ducts are connected end-to-end along the airflow direction. The fan 43 is mounted on the thermal storage tank 41 and is used to direct the hot air from the thermal storage tank 41 to the heat dissipation pipe via a conduit.

[0038] The air cooling system 40 collects the heat generated by the film through the heat storage box 41, and draws the outside air into the box through the fan 43 to dissipate heat, so that the film can reduce a certain stability and avoid deformation caused by direct water cooling; at the same time, the fan 43 guides the hot air flow to the heat dissipation air pipe 42, and the heat dissipation air pipe 42 uses the heat of the hot air to cool the water-cooled film.

[0039] Please continue to refer to Figure 1 A forced air duct 50 is mounted on the crossbeam 12, located between the water tank 31 and the air duct along the film's transport direction. The duct 50 is connected to an external forced air blower (not shown). The ducts 50 are located on both the top and bottom sides of the film, each with an air outlet 51 facing the film's surface. After cooling in the water tank 31, the film is dried by the ducts 50.

[0040] Please continue to refer to Figure 1 The two ends of the contact sensor 60 are mounted on two parallel beams 12. The contact sensor 60 is perpendicular to the beams 12. The contact sensor 60 is used to detect whether the rolled-up film deviates from the preset track. The contact sensor 60 is externally connected to a signal processor (not shown). The contact sensor 60 can detect the position of the film by detecting the pressure of the film.

[0041] Please refer to Figures 1 to 4 The deviation correction assembly 70 includes a rotating shaft 71, a sleeve 72, an adjustment stopper 73, and a telescopic motor 74. The two ends of the rotating shaft 71 are respectively mounted on the two parallel beams 12 of the bracket 10. The sleeve 72 is rotatably mounted on the rotating shaft 71, and the diameter of the sleeve 72 is larger than the diameter of the rotating shaft 71. The adjustment stopper 73 is mounted on the rotating shaft 71 and can slide along the length direction of the rotating shaft 71. The adjustment stopper 73 slides to block both sides of the film in the width direction to adjust the position of the film in the length direction of the rotating shaft 71; the adjustment stopper 73 is provided at both ends of the sleeve 72. The telescopic motor 74 is mounted on the beam 12, and the output shaft 741 of the telescopic motor 74 is connected to the adjustment stopper 73. The telescopic motor 74 is used to drive the output shaft 741 to extend or retract according to the signal of the contact sensor 60, adjust the position of the adjustment stopper 73 in the length direction of the rotating shaft 71, and thus adjust the position of the film in the length direction of the roller 20.

[0042] The adjustment stopper 73 comprises an adjustment seat 731, a sleeve 732, and a baffle 733. The adjustment seat 731 is mounted on the rotating shaft 71 and is slidable along the length of the rotating shaft 71. Specifically, the adjustment seat 731 is fixedly connected to the output shaft 741 of the telescopic motor 74. The sleeve 732 is mounted on the rotating shaft 71 and is rotatably connected to the adjustment seat 731. The sleeve 732 moves along the length of the rotating shaft 71 with the adjustment seat 731. The baffle 733 is fixedly mounted on the sleeve 732 to prevent the film from moving along the length of the rotating shaft 71, thereby adjusting the film's position along the length of the rotating shaft.

[0043] Please combine Figure 5 The sleeve 732 is conical in shape, with the diameter of the end of the sleeve 732 closest to the telescopic motor 74 being larger than the end further away from the motor. A baffle 733 is fixed to the end of the sleeve 732 closest to the motor 74, forming a conical surface. Specifically, one surface of the adjustment seat 731 is convex to form a protrusion 7311, while the end surface of the sleeve 732 closest to the telescopic motor 74 is concave to form a mounting opening 7322 corresponding to the protrusion 7311. The protrusion 7311 and the mounting opening 7322 are connected by a bearing 734, thereby achieving a rotatable connection between the sleeve 732 and the adjustment seat 731. The two conical sleeves 732 generate a force along the center of the rotating shaft 71, which can prevent the film from shifting to a certain extent.

[0044] An installation opening 7321 corresponding to the sleeve 732 is opened at one end of the sleeve 732 away from the telescopic motor 74 , and both ends of the sleeve 72 extend into the installation openings 7321 of the sleeve 732 on both sides.

[0045] When the film deviates, the signal processor sends a signal, and the telescopic motor 74 adjusts the extension and contraction of its output shaft 741, driving the adjustment seat 731 on the adjustment stop 73 to move, thereby driving the conical sleeve 732 to move, and the baffle 733 squeezes the side of the film, so that the film can be deviated to the correct position.

[0046] Following film transport, after being extruded and formed, the film first passes through the heat storage tank 41 for preliminary cooling, reducing its temperature to a certain level. It then passes through the extension frame 13, changing its transport path downward and entering the water storage tank 31 for water cooling. After water cooling, the film reaches the strong air duct 50, which blows strong air to remove moisture from the film's surface. The film then passes through the air and water ducts 321, where waste heat is used to evaporate water vapor from the film, dehumidifying and thoroughly drying it. The hot air from the air duct is then discharged into the air, while the water from the water duct 321 flows back into the water storage tank 31. The film then flows through the contact sensor 60 and the deflection correction assembly 70, ultimately reaching the rewinding roller 20. If the film deviates from the preset position, the deflection correction assembly 70 receives signals from the contact sensor 60 and corrects the deviation, ensuring proper rewind alignment.
