Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a unidirectional stretching molding device for polyimide film, including a base 1, a control box 11 fixedly connected to one end of the base 1, and a film body 12 disposed above the base 1. A limiting component 2 is disposed at one end of the film body 12, and the limiting component 2 includes a fixing plate 21 disposed on the outer side of one end of the film body 12. A first electric telescopic rod 22 is fixedly connected to one end of the fixing plate 21, and a pressure plate 23 is fixedly connected to the end of the first electric telescopic rod 22 away from the fixing plate 21. A roller 24 is rotatably connected to the upper end of the pressure plate 23, and a guiding component 3 is disposed on the inner side of one end of the film body 12. Adjusting components 4 are disposed at both ends of the guiding component 3, and a supporting component 5 is disposed at the end of the film body 12 away from the guiding component 3. A wire assembly 6 is disposed on the upper end of the supporting component 5, and extrusion components 7 are disposed at both ends of the wire assembly 6. By cooperating with the limiting component 2 and the guiding component 3, when one end of the film body 12 is clamped and stretched, the clamping marks caused by clamping the film body 12 are reduced, thereby reducing material loss.

[0025] like Figure 2 As shown, the guiding component 3 includes a first guiding roller 31 inserted into the inner side of one end of the membrane body 12, and a second guiding roller 32 is provided at one end of the first guiding roller 31. The first guiding roller 31 and the second guiding roller 32 are used to restrict the other end of the membrane body 12.

[0026] like Figure 2As shown, the adjustment assembly 4 includes a first bracket 41 rotatably connected to the two ends of the first guide roller 31 and the second guide roller 32. A threaded plate 42 is fixedly connected to the lower end of the first bracket 41. A threaded rod 43 is threadedly engaged on the inner side of the lower end of the threaded plate 42. One end of the threaded rod 43 is rotatably connected to the base 1. The other end of the threaded rod 43 passes through the base 1 and is fixedly connected to the motor 44. The end of the motor 44 near the base 1 is fixedly connected to the base 1. By starting the motor 44, the output shaft of the motor 44 can drive the threaded rod 43 to rotate. Thus, by utilizing the threaded engagement between the threaded rod 43 and the threaded plate 42, the threaded plate 42 can drive the first bracket 41 to move.

[0027] like Figure 1 As shown, the support assembly 5 includes a support plate 51 disposed on the outer side of the membrane body 12 away from the control box 11, and the lower end of the support plate 51 is fixedly connected to the base 1, and the upper end of the support plate 51 is fixedly connected to the top plate 52.

[0028] like Figure 2 and Figure 4 As shown, the conductor assembly 6 includes a third guide roller 61 rotatably connected to the inner side of the upper end of the support plate 51, and a fourth guide roller 62 is provided at one end of the third guide roller 61. The third guide roller 61 and the fourth guide roller 62 are used to restrict one end of the membrane 12.

[0029] like Figure 2 and Figure 4 As shown, the extrusion assembly 7 includes a second bracket 71 rotatably connected to both ends of the fourth guide roller 62, and a second electric telescopic rod 72 is fixedly connected to the lower end of the second bracket 71. The operation of the second electric telescopic rod 72 pushes the second bracket 71 to move, thereby allowing the second bracket 71 to drive the fourth guide roller 62 to move.

[0030] like Figure 2 and Figure 4 As shown, three sets of second electric telescopic rods 72 are installed on the lower side of a set of second brackets 71, and the lower end of the second electric telescopic rods 72 is fixedly connected to the base 1.

[0031] Working principle: When stretching the membrane 12, the membrane 12 is first passed through the lower end of the third guide roller 61 and wrapped around the outside of the fourth guide roller 62. Then, it passes around the upper end of the second guide roller 32 and through the lower end of the first guide roller 31. When stretching the membrane 12 is required, the second electric telescopic rod 72 is activated to push the second support 71 to move, thereby causing the second support 71 to drive the fourth guide roller 62 to move upward, cooperating with the top plate 52 to squeeze and restrict one end of the membrane 12. Then, the first electric telescopic rod 22 is activated to push the pressure plate 23 to move under the support of the fixed plate 21, thereby causing the pressure plate 23 to cooperate with the first guide roller 31 to squeeze and restrict the other end of the membrane 12. After the two ends of the membrane 12 are restricted, the motor 44 can be started. After the motor 44 is started, the output shaft drives the threaded rod 43 to rotate, so that the threaded rod 43 engages with the threaded plate 42, causing the threaded plate 42 to drive the first support 41 to move. After the first support 41 moves, it drives the first guide roller 31 and the second guide roller 32 to stretch the membrane 12. After stretching, the first electric telescopic rod 22 is closed, causing it to drive the pressure plate 23 away from the first guide roller 31, thereby releasing the restriction on the membrane 12. Then the second electric telescopic rod 72 is closed, causing it to retract and drive the second support 71 back to its position. Then the membrane 12 is pulled to stretch with the assistance of the roller 24.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
