Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a waterproof and breathable film winding structure. Background Technique

[0002] A waterproof and breathable film is a kind of polymer microporous waterproof material, which is formed by extrusion and expansion stretching with PTFE resin as the raw material. This material has a special fibrous microporous structure, so it has excellent waterproof and breathable properties. It has high mechanical properties and small pore size, can prevent air flow accumulation, and can quickly balance the pressure inside and outside the sealed cavity.

[0003] In the prior art, a simple winding roller device is often used in the market to wind the waterproof and breathable film. Although the structure is simple and not easy to be damaged, the winding efficiency is relatively low. In addition, when the winding mechanism winds the waterproof and breathable film, due to factors such as the material and thickness of the film, as well as the winding speed and tension, the film will be loose in the middle part, resulting in poor winding effect and inconvenience for carrying and transportation. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. Many winding mechanisms have low efficiency in winding the waterproof and breathable film, and during the winding process, the internal multi-layer structure is prone to loose winding, resulting in poor winding effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a waterproof and breathable film winding structure, including a base, on the top of the base, a conveying frame, a lifting frame and a driving frame are sequentially arranged. An input roller is rotatably connected inside the conveying frame, a main driving roller is rotatably connected inside the driving frame, the main driving roller is connected to the output end of a first servo motor outside the driving frame through a reserved through hole, a power synchronization mechanism is installed between the input roller and the main driving roller, a winding roller is also rotatably connected on the top of the input roller, a second servo motor is fixedly installed on one side of the conveying frame close to the winding roller, and the output end of the second servo motor is also connected to the winding roller through a reserved through hole. Two opposite tension mechanisms are arranged inside the lifting frame, and one end of each of the two tension mechanisms is connected to a tension roller.

[0006] Optionally, the power synchronization mechanism includes a driven belt pulley, a rubber belt and a driving belt pulley. The input roller passes through the conveying frame and is fixedly connected to the driven belt pulley outside, the main driving roller passes through the driving frame and is fixedly connected to the driving belt pulley outside, and a rubber belt for belt transmission is arranged between the driven belt pulley and the driving belt pulley.

[0007] Optionally, the tension mechanism includes a rectangular slot, a chute, a slider, and a spring. A chute is provided inside the lifting frame. A spring is installed on the bottom surface inside the chute. A slider is provided on top of the spring. The slider is slidably connected inside the lifting frame. A vertically arranged rectangular slot is opened on the outer shell of the lifting frame near one side of the tension roller. One end of the slider close to the rectangular slot is fixedly connected to the tension roller.

[0008] Optionally, a pressure switch is provided on one side of the rectangular slot close to the tension roller.

[0009] Optionally, the rotational speed of the second servo motor is slightly greater than that of the first servo motor.

[0010] Optionally, a controller is installed on the outer side of the conveying frame.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0012] 1. In the present utility model, the waterproof and breathable film is first introduced into the winding mechanism from the input roller. The main driving roller is driven to rotate by the first servo motor. The main driving roller drives the input roller to rotate synchronously through the synchronization mechanism, thereby conveying the waterproof and breathable film upward. The waterproof and breathable film is conveyed by the main driving roller to the tension roller above, is transferred by the tension roller and then continues to be conveyed backward, and finally is wound by the winding roller. Since the rotational speed of the second servo motor is slightly greater than that of the first servo motor, the waterproof and breathable film can be always tightened during winding, reducing the loose phenomenon that is likely to occur during the film winding process, thereby improving the winding effect. At the same time, the tension mechanism provides a certain upward elastic force to prevent the waterproof and breathable film from being overly tightened due to the different rotational speeds of the two servo motors, resulting in breakage.

[0013] 2. In the present utility model, when the tension roller presses down to the bottom of the rectangular slot, the pressure switch is triggered. The pressure switch transmits a signal to the controller. The controller controls the second servo motor to decelerate through the built-in microprocessor, temporarily making the rotational speed of the second servo motor slightly lower than that of the first servo motor. At this time, the spring is no longer under the pressure of the tension roller and pushes up the slider and the tension roller, thereby resetting the tension roller to the top of the rectangular slot and restoring the previous rotational speed of the second servo motor, preventing the waterproof and breathable film from breaking.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment

[0020] As Figure 1 and Figure 2 shown, the present invention provides a technical solution: a waterproof and breathable film winding structure, including a base 1, on the top of the base 1, a conveyor frame 2, a lifting frame 4 and a driving frame 3 are sequentially arranged. Inside the conveyor frame 2, an input roller 5 is rotatably connected. Inside the driving frame 3, a main driving roller 10 is rotatably connected. The main driving roller 10 is connected to the output end of the first servo motor 6 outside the driving frame 3 through a reserved through hole. A power synchronization mechanism is installed between the input roller 5 and the main driving roller 10. A winding roller 12 is also rotatably connected to the top of the input roller 5. A second servo motor 11 is fixedly installed on one side of the conveyor frame 2 close to the winding roller 12. The output end of the second servo motor 11 is also connected to the winding roller 12 through a reserved through hole. Inside the lifting frame 4, two opposite tension mechanisms are provided. One end of each of the two tension mechanisms is connected to a tension roller 14. The rotation speed of the second servo motor 11 is slightly greater than that of the first servo motor 6.

[0021] In this embodiment, the waterproof and breathable film is first introduced from the input roller 5 into the winding mechanism. The first servo motor 6 drives the main driving roller 10 to rotate. The main driving roller 10 drives the input roller 5 to rotate synchronously through the synchronization mechanism, so as to convey the waterproof and breathable film upward. The waterproof and breathable film is conveyed by the main driving roller 10 to the tension roller 14 above, and after being transferred by the tension roller 14, it continues to be conveyed backward and is finally wound by the winding roller 12. Since the rotational speed of the second servo motor 11 is slightly greater than that of the first servo motor 6, the waterproof and breathable film can be always tightened during winding, reducing the loose phenomenon that is likely to occur during the winding process of the film, thereby improving the winding effect. At the same time, the tension mechanism provides a certain upward elastic force to prevent the waterproof and breathable film from being overly tightened due to the different rotational speeds of the two servo motors, resulting in breakage. The above mechanism adopts an electric mechanical mechanism, and its winding efficiency is greatly improved compared with the traditional simple manual winding device.

[0022] The power synchronization mechanism includes a driven pulley 7, a rubber belt 8 and a driving pulley 9. The input roller 5 passes through the conveying frame 2 and is fixedly connected to the driven pulley 7 on the outside. The main driving roller 10 passes through the driving frame 3 and is fixedly connected to the driving pulley 9 on the outside. A rubber belt 8 for belt transmission is arranged between the driven pulley 7 and the driving pulley 9.

[0023] In this embodiment, the power is transmitted from the driving pulley 9 to the driven pulley 7 by using the friction force and tension on the surface of the rubber belt 8, and the power is transmitted by forming a friction force on the surface of the rubber belt 8.

[0024] The tension mechanism includes a rectangular slot 13, a chute 15, a slider 16 and a spring 17. The inside of the lifting frame 4 is provided with a chute 15. The bottom surface inside the chute 15 is provided with a spring 17. The top of the spring 17 is provided with a slider 16. The slider 16 is slidably connected inside the lifting frame 4. A vertically arranged rectangular slot 13 is opened on the outer shell of the lifting frame 4 near the tension roller 14. One end of the slider 16 close to the rectangular slot 13 is fixedly connected to the tension roller 14.

[0025] In this embodiment, the spring 17 can provide an upward elastic force to the slider 16, thereby driving the slider 16 and transmitting the upward elastic force to the tension roller 14, so that the tension roller 14 also has an upward elastic force.

[0026] A pressure switch 18 is arranged on one side of the rectangular slot 13 close to the tension roller 14, and a controller 19 is installed outside the conveying frame 2.

[0027] In this embodiment, when the tension roller 14 is pressed down to the bottom of the rectangular slot 13, the pressure switch 18 is triggered. The pressure switch 18 transmits a signal to the controller 19, and the controller 19 controls the second servo motor 11 to decelerate through the built-in microprocessor, temporarily making the rotational speed of the second servo motor 11 slightly lower than that of the first servo motor 6. At this time, the spring 17 is no longer under the pressure of the tension roller 14, and jacks up the slider 16 and the tension roller 14, thereby resetting the tension roller 14 to the top of the rectangular slot 13 and restoring the previous rotational speed of the second servo motor 11 to prevent the waterproof and breathable film from breaking.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
