TECHNICAL FIELD

[0001] The application relates to a film winding frame. BACKGROUND

[0002] The existing film winding frame usually adopts a simple mechanical structure, and the winding process is controlled by fixed tension or manual adjustment. Due to the lack of automatic adjustment mechanism, it is difficult to flexibly adjust the tension according to the specific characteristics of the film and the real-time situation. In the high-speed winding process, once the external traction device stops working, the winding frame will continue to rotate for a period of time due to inertia. In this case, if it cannot be effectively braked in time, the film will be irregularly covered, and even wrinkles or damage will be caused, which seriously affects the product quality. SUMMARY

[0003] The technical problem to be solved by the application is to overcome the existing defects and provide a film winding frame which can effectively solve the problems in the background art.

[0019] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application (for the convenience of description and understanding, the following description is from the top to the bottom), all other embodiments obtained by a person of ordinary skill in the art without creative labor are within the scope of protection of the application. Figure 2

[0020] Please refer to Figures 1-5 , the application provides a technical solution: a winding frame for film laying, comprising a base 1, the upper surface of the base 1 is provided with a rotating seat 4, the rotating seat 4 is sleeved with a rotating shaft 14.

[0021] The base 1 provides a stable support platform, ensuring that the device does not shift or fall during work. It bears the weight of all the upper structures.

[0022] ​The rotating seat 4 is located on the base 1, and the rotating shaft 14 is sleeved in the rotating seat 4; the rotating seat 4 provides a stable rotating environment for the rotating shaft 14, and can bear the torque force generated during the film winding.

[0023] The rotating seat 4 is provided with the friction disc 6 on both sides, the rotating shaft 14 is provided with the inner disc 2 and the outer wheel 3 on the outer side, the inner disc 2 and the outer wheel 3 are separately located on both sides of the rotating shaft 14, and the outer wheel 3 is installed on one side of the rotating shaft 14 through the fastener.

[0024] The friction disc 6 is located on one side of the rotating seat 4, is connected with the rotating shaft 14 through the double round head flat key 7, and provides necessary friction force to control the tension during the film winding, so that the film can be uniformly and tightly wound on the outer wheel 3.

[0025] The spring 9 is arranged between the friction disc 6 and the thin nut 13, and when the tension needs to be adjusted during the winding process, the spring 9 can automatically adjust the pressure of the inner disc 2 and the outer wheel 3 according to the actual situation, so that the free rotation is avoided, and the film folding is caused.

[0026] The inner disc 2 is located on one side of the rotating shaft 14, and the inner side of the inner disc 2 is provided with an insertion shaft seat for limiting the film frame arranged between the inner disc 2 and the outer wheel 3, so that the stability and accuracy during the winding process are ensured.

[0027] Further, the vertical section of the rotating seat 4 is provided with a connecting flange plate, and the connecting flange plate is connected to the upper end of the base 1 through the pull ring pin 5.

[0028] The vertical section of the rotating seat 4 is provided with a connecting flange plate, and the connecting flange plate is connected to the upper end of the base 1 through the pull ring pin 5, the upper end of the base 1 is provided with through holes in the circumference, the pull ring pin 5 passes through the through holes of the rotating seat 4 and the base 1 and is connected, the position of the rotating seat 4 can be limited, and unnecessary shaking or loosening phenomenon is avoided.

[0029] Further, the end of the rotating shaft 14 located at the left end of the rotating seat 4 is a threaded part, and the threaded part is connected with the thin nut 13.

[0030] Further, the spring 9 is arranged between the friction disc 6 and the thin nut 13.

[0031] The thin nut 13 is installed on the threaded part of the rotating shaft 14, and is used for adjusting the pressure of the spring 9 on the friction disc 6; when the thin nut 12 is tightened, the spring 9 is compressed, and the pressure of the friction disc 6 on the rotating shaft 14 is increased; conversely, loosening the thin nut 12 can reduce the pressure; in addition to adjusting the pressure, the thin nut 13 also plays a locking role, so that once the appropriate tension is set, the components will not be displaced due to external factors (such as vibration), and the stability of the winding process is ensured.

[0032] Further, the spring 9 and the thin nut 13 are provided with a washer 10.

[0033] The washer 10 is placed between the spring 9 and the thin nut 13, effectively preventing the wear that may occur when the two are in direct contact. Since the thin nut 13 will be rotated frequently during adjustment, direct contact with the spring 9 may cause metal fatigue or deformation at the end of the spring 9, affecting its elasticity and working performance. The washer 10 as an intermediate layer can significantly reduce such wear and prolong the service life of the spring 9.

[0034] The washer 10 also helps to evenly distribute the pressure exerted by the thin nut 13 on the end face of the spring 9, improving the working stability of the spring 9, and avoiding the problem of spring 9 failure or deformation caused by excessive local pressure.

[0035] Further, the friction disc 6 and the rotating shaft 14 are provided with a double round head key 7.

[0036] Further, the friction disc 6 and the rotating shaft 14 are provided with a friction plate 8.

[0037] The friction plate 8 provides sufficient friction to help control the tension of the film during winding. When the rotating shaft 14 rotates, the friction between the friction plate 8 and the friction disc 6 can adjust the winding speed and tightness of the film, thereby ensuring that the film can be uniformly and stably wound on the film carrier located between the inner disc 2 and the outer wheel 3.

[0038] Further, the inner wall steps at both ends of the rotating seat 4 are provided with deep groove ball bearings 11, and the left side of the deep groove ball bearing 11 at the left end is provided with a shaft clamp spring 12.

[0039] In use: set the friction disc 6 at the initial position, and set a proper initial tension by adjusting the spring 9 and the thin nut 13, pull out the mounting pin shaft on one side of the outer wheel 3, remove the outer wheel 3, clamp the film carrier on the shaft seat on one side of the inner disc 2, fix the film carrier, at this time, install the outer wheel 3, fix the film to be wound on the film carrier, turn on other power sources, and make the rotating shaft 14 rotate the outer wheel 3, thereby starting the film winding and unwinding. In the initial winding stage, closely observe the film winding condition, and if necessary, slightly rotate the thin nut 13 to fine-tune the tension; ensure that it is uniform and tight, and avoid loose or too tight situations. If the winding is uneven or the speed needs to be adjusted, adjust the thin nut 13 in time to change the pressure of the spring 9, thereby affecting the pressure of the friction disc 6 on the rotating shaft 14, achieving control of the winding speed. If the film slips or winds irregularly, stop the power source immediately, check the state of the friction plate 8 and the friction disc 6, ensure that there is enough friction between them, and if necessary, adjust the tension setting or check other factors that may affect the winding effect.
