DETAILED DESCRIPTION
[0022] See also Figure 1-5 The utility model provides a technical solution: a winding device with tension adjustment function for film extrusion, comprising a winding component 1 and a tension adjustment component 2 used in conjunction with the winding component 1, a workbench 3 is arranged at the bottom of the winding component 1, and the tension adjustment component 2 is located at one side of the winding component 1; the winding component 1 comprises a fixed frame 11, a winding motor 12 and a winding roller 13, the winding roller 13 is connected to the fixed frame 11 through a bearing seat, the winding motor 12 is located on the outer wall of one side of the fixed frame 11, and one end of the winding roller 13 penetrates the fixed frame 11 and is connected to the winding motor 12 through a fixed coupling; the tension adjustment component 2 is higher than the film discharging machine outlet and the winding component 1.
[0023] It should be noted that the tension adjustment component 2 of the present application can automatically adjust the tension according to the tension of the film during the winding process of the winding component 1, so as to prevent the film from being deformed to a large extent during the tension adjustment, thereby causing the film to be pulled too much and affect the quality or even break.
[0024] Furthermore, when the film outlet is subjected to external force or other sharp objects and the film is torn and broken, the tension adjustment component 2 performs tension limit adjustment to prevent the film from being suddenly broken and causing the winding film to be deformed, which affects the problem of winding and forming. The structure is simple and the operation is convenient;
[0025] Furthermore, the height of the tension adjustment component 2 is higher than the film dispensing machine outlet and the winding component 1. The winding component 1 cooperates with the tension adjustment component 2 to adjust the tension. When the film passes through the tension adjustment component 2 and reaches the winding component 1 during the winding process, the film is in a tensioned state. When the film tension weakens, the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension chute 211. Since both sides of the film are connected to the film dispensing machine and the winding component 1, the film has a downward pulling force, and the film is in an optimal tension state at this time.
[0026] Furthermore, when the film outlet is subjected to external force or other sharp objects and the film is torn and broken, the tension at the film outlet becomes smaller or exists. At this time, the film tension becomes smaller or does not exist, and the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension slide groove 211, and the electromagnet 26 squeezes the film breakage limit tension plate 25, and the film breakage limit tension plate 25 moves downward and the telescopic block 243 moves toward the inside of the first groove 241. At this time, the two sides of the film breakage limit tension plate 25 abut against the top of the winding roller 13, and the winding assembly 1 continues to wind to prevent the film from breaking suddenly. The disappearance of tension causes the winding film to deform, affecting the winding forming.
[0027] See also Figure 2-4 The tension adjustment component 2 includes a support frame 21 and an automatic adjustment component which are parallel and symmetrically arranged on the left and right sides. The bottom of the support frame 21 is connected to the top of the workbench 3, and the automatic adjustment component is located between the two support frames 21; the automatic adjustment component includes a fixed shaft 22, and a tension roller 23 is rotatably sleeved in the middle of the fixed shaft 22. Fixed bearings 24 are sleeved on the fixed shaft 22 at both ends of the tension roller 23. Each fixed bearing 24 is provided with a first groove 241, and a telescopic block 243 is connected to the inside of each first groove 241 through a first spring 242. A membrane rupture limit tension plate 25 is arranged between the two telescopic blocks 243 above the tension roller 23, and a membrane rupture limit tension plate 25 is arranged between the two telescopic blocks 243. The force plate 25 is an arc-shaped plate structure with a convex top and a concave inside; the support frames 21 located at both ends of the fixed shaft 22 are provided with tension slide grooves 211, and the tension slide grooves 211 are parallel to the support frames 21. The two ends of the fixed shaft 22 are located at the bottom of the tension slide grooves 211. A tension adjustment spring 221 is arranged on the end of the fixed shaft 22 located inside the tension slide grooves 211. One end of the tension adjustment spring 221 is fixed to the top of the end of the fixed shaft 22, and the other end of the tension adjustment spring 221 is fixed to the top inside the tension slide groove 211; an electromagnet 26 is connected and arranged between the tops of the two support frames 21; an iron plate used in conjunction with the electromagnet 26 is arranged inside the fixed shaft 22.
[0028] It should be noted that, in the present embodiment, by setting the tension adjustment component 2, the tension can be automatically adjusted according to the tension of the film during the winding process of the winding component 1, so as to prevent the film from being deformed to a large extent during the tension adjustment, thereby causing the film to be pulled too much and affecting the quality or even breaking. The height of the tension adjustment component 2 is higher than the outlet of the film discharging machine and the winding component 1. The winding component 1 cooperates with the tension adjustment component 2 to adjust the tension. When the film passes through the tension adjustment component 2 and reaches the winding component 1 during the winding process, the film is in a tensioned state;
[0029] When the film tension becomes weak, the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension chute 211. Since both sides of the film are connected to the film discharging machine and the winding assembly 1, the film has a downward pulling force. The attraction of the electromagnet 26 is the same as the downward pulling force. At this time, the film is in an optimal tension state.
[0030] Furthermore, when the film outlet is subjected to external force or other sharp objects and the film is torn and broken, the tension at the film outlet becomes smaller or exists. At this time, the film tension becomes smaller or does not exist, and the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension slide groove 211, and the electromagnet 26 squeezes the film breakage limit tension plate 25, and the film breakage limit tension plate 25 moves downward and the telescopic block 243 moves toward the inside of the first groove 241. At this time, the two sides of the film breakage limit tension plate 25 abut against the top of the winding roller 13, and the winding assembly 1 continues to wind to prevent the film from breaking suddenly. The disappearance of tension causes the winding film to deform, affecting the winding forming.
[0031] The working process of the utility model is as follows: when in use, the film at the film outlet is passed through the tension roller 23 on the tension adjustment component 2 and connected to the winding roller 13, the electromagnet 26 is energized, and the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension chute 211. Since the two sides of the film are connected to the film discharging machine and the winding component 1, the film has a downward pulling force. At this time, the film is in an optimal tension state. When the downward pulling force of the film becomes larger, the film pulls the fixed shaft 22 to slide downward in the tension chute 211. When the downward pulling force of the film becomes smaller and the tension becomes smaller, the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension chute 211. Since the two sides of the film are connected to the film discharging machine and the winding component 1, the film has a downward pulling force. The attraction force of the electromagnet 26 is the same as the downward pulling force. At this time, the film is in an optimal tension state.
[0032] When the film outlet is subjected to external force or other sharp objects and the film is torn and broken, the tension at the film outlet becomes smaller or exists. At this time, the film tension becomes smaller or does not exist, and the suction force of the electromagnet 26 attracts the iron plate inside the fixed shaft 22, driving the fixed shaft 22 to slide upward in the tension slide groove 211, and the electromagnet 26 squeezes the film breakage limit tension plate 25, and the film breakage limit tension plate 25 moves downward and the telescopic block 243 moves toward the inside of the first groove 241. At this time, the two sides of the film breakage limit tension plate 25 abut against the top of the winding roller 13, and the winding assembly 1 continues to wind to prevent the film from breaking suddenly. The disappearance of tension causes the winding film to deform, affecting the winding forming.
