Description

Technical Field

[0001] The utility model belongs to the technical field of reflective film production, and in particular relates to a mould for preventing reflective film from wrinkling. Background Art

[0002] In the prior art, the reflective film mold has serious wrinkles and unevenness problems during the operation of the embossing machine. During the production process, after the mold is opened by the cylinder, the distance between the driving roller and the driven roller is more than 70CM. The mold is loose and deformed due to the lack of support for the suspended part. Therefore, the mold is deformed and damaged after the machine runs for a long time because there is no support.

[0003] The prior art discloses a mold for preventing reflective film from wrinkling (patent announcement number: CN220113999U), which drives the load-bearing wheel through an elastic member to apply an upward tightening force to the reflective film to prevent the reflective film from wrinkling during transportation. However, the following deficiencies are found in actual use: during use, it is often necessary to adjust the distance between the driven roller and the active roller according to the usage situation, and the load-bearing wheel in a fixed position cannot meet the demand. After adjustment, the load-bearing wheel cannot be placed in the center position, and then the reflective film is unevenly stressed during the tightening process. In addition, when wrinkles occur, the load-bearing shaft will move up, causing the center of the solid reflective film to warp up, thereby reducing the contact area with the power roller, affecting the conveying power. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a mold for preventing the reflective film from wrinkling, which can achieve the tightening of the reflective film to prevent such phenomenon from occurring during transportation.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mold for preventing wrinkles of a reflective film comprises a support frame, wherein a slide groove A is symmetrically provided on the inner wall of one end of the support frame, a threaded rod is installed inside the slide groove A through a bearing, a slider A is slidably installed inside the slide groove A, the slider A is screwed on the threaded rod, a driven roller is rotatably installed between two of the sliders A, a power roller is installed on the inner side of one end of the support frame away from the driven roller, a reflective film body is wound around the surfaces of the power roller and the driven roller, tracks are symmetrically provided on both sides of the upper surface of the support frame, the track cross-section is T-shaped, a moving seat is slidably installed on the surface of the track, a slide groove B is vertically provided on the surface of the moving seat, a slider B is slidably installed on the inner side of the slide groove B, a cross plate is provided between the two sliders B, the cross plate spans above the reflective film body, the cross plate is placed between the driven roller and the power roller, lower extension plates are symmetrically provided below the cross plate, an adjustment roller is rotatably installed between the two lower extension plates, and the adjustment roller contacts the upper surface of the reflective film body.

[0007] Further, a limiting plate is installed on the surface of the slider B facing away from the cross plate by bolts. The limiting plate is placed outside the moving seat, and the lateral dimension of the limiting plate is larger than that of the slider B.

[0008] Further, a sliding bolt is vertically arranged at the center of the upper surface of the slider B. The sliding bolt extends beyond the upper surface of the moving seat, and scale values are uniformly engraved on the surface of the sliding bolt.

[0009] Further, positioning holes are uniformly formed on the upper surface of the track, and the positioning holes are internal threaded holes.

[0010] Further, locking bolts penetrate through both sides of the moving seat, and the end of the locking bolt is adapted to the internal dimension of the positioning hole.

[0011] Further, the threaded rod extends beyond the end surface of the support frame, and a knob is arranged at the end of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the reflective film is wrinkled during use, the self-weight of the adjusting roller can be utilized to tighten the reflective film to keep the reflective film in a flat state and prevent wrinkling. The downward pressing tightening method increases the contact surface between the reflective film and the surface of the driving roller, thereby increasing the relative friction and preventing slipping.

[0013] When the distance between the driving roller and the driven roller changes, the adjusting roller can be controlled to move according to the usage situation so that it is located between the driving roller and the driven roller to ensure that the reflective film on both sides of the adjusting roller is evenly stressed during tightening during transportation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1 As shown, a mold for preventing reflective film from wrinkling includes a support frame 1, and a slide groove A2 is symmetrically opened on the inner wall of one end of the support frame 1. The slide groove A2 is opened horizontally, and a threaded rod 4 is installed inside the slide groove A2 through a bearing. A slider A3 is slidably installed inside the slide groove A2, and the slider A3 is screwed on the threaded rod 4. The threaded rod 4 exceeds the end surface of the support frame 1. A knob 41 is set at the end of the threaded rod 4. The movement of the slider A3 is controlled by rotating the external knob 41, and then the distance between the driven roller 5 and the power roller 6 is controlled. In different use environments, the reflective film body 7 can also be tightened by increasing the distance to preliminarily prevent wrinkles.

[0021] Please refer to Figures 1 - 3 As shown, a driven roller 5 is rotatably installed between the two sliders A3, a power roller 6 is installed on the inner side of the end of the support frame 1 away from the driven roller 5, the power roller 6 is controlled by a driving motor, and a reflective film 7 is wound around the surface of the power roller 6 and the driven roller 5 to transport and move the reflective film 7, and tracks 8 are symmetrically arranged on both sides of the upper surface of the support frame 1. The cross section of the track 8 is T-shaped. The T-shaped structure allows the moving seat 9 to slide only along the surface of the track 8. The moving seat 9 is slidably installed on the surface of the track 8. A slide groove B10 is vertically opened on the surface of the moving seat 9, and a slider B11 is slidably installed inside the slide groove B10. The two sliders B A transverse plate 13 is arranged between 11, and the transverse plate 13 can move up and down. The transverse plate 13 spans above the reflective film body 7, and the transverse plate 13 is placed between the driven roller 5 and the power roller 6. A lower extension plate 14 is symmetrically arranged below the transverse plate 13, and an adjustment roller 15 is rotatably installed between the two lower extension plates 14. The adjustment roller 15 contacts the upper surface of the reflective film body 7, and uses its own weight to press down and tighten the reflective film body 7 to prevent wrinkles. When the reflective film body 7 is loose and wrinkled, the downward pressure of the adjustment roller 15 can make the center of the reflective film body 7 move downward, increase the contact area with the power roller 6, and ensure the transmission power.

[0022] Among them, when the driven roller 5 moves, the distance between the driven roller 5 and the power roller 6 changes, and when the reflective film 7 relaxes the wrinkles, the pressure roller 15 moves downward due to its own weight adjustment, and the movable seat 9 automatically moves to the center position of the driven roller 5 and the power roller 6 to ensure the force distance.

[0023] Please refer to Figure 2 and Figure 3As shown, a limiting plate 12 is installed on the side surface of the slider B11 facing away from the cross plate 13 by bolts. The limiting plate 12 is placed outside the moving seat 9, and the transverse dimension of the limiting plate 12 is larger than that of the slider B11 to limit the slider B11, so that the slider B11 and the cross plate 13 can only move in the vertical direction.

[0024] Please refer to Figure 2 and Figure 3 As shown, a sliding bolt 16 is vertically arranged at the center of the upper surface of the slider B11. The sliding bolt 16 extends beyond the upper surface of the moving seat 9, and scale values 161 are evenly engraved on the surface of the sliding bolt 16 to observe and adjust the height of the pressing roller 15 for easy adjustment and control.

[0025] Please refer to Figure 1 and Figure 2 As shown, positioning holes 81 are evenly formed on the upper surface of the track 8. The positioning holes 81 are internal threaded holes. Locking bolts 91 penetrate through both sides of the moving seat 9, and the end of the locking bolt 91 is adapted to the internal dimension of the positioning hole 81. When the adjusting pressing roller 15 is placed at the middle position between the driving roller 6 and the driven roller 5, the moving seat 9 can be fixed.

[0026] The working principle of the present utility model is as follows: According to the usage situation, the knob 41 can be rotated to drive the threaded rod 4 to rotate, and then control the movement of the slider A3 inside the chute A2 to adjust the distance between the driven roller 5 and the driving roller 6 and achieve self-locking fixation. Then, the position of the moving seat 9 is adjusted, and the cooperation of the locking bolt 91 and the positioning hole 81 is used to keep the position of the moving seat 9 stable. Due to its own weight, the adjusting pressing roller 15 is always subjected to a downward force, and then the slider B11 is always subjected to a downward pressure inside the chute B10. The reflective film body 7 is penetrated under the lower surface of the adjusting pressing roller 15. When the reflective film body 7 occurs like this, it can be tightened by the self-weight downward pressure of the adjusting pressing roller 15, and then wrinkles are prevented. Since the sliding bolt 16 penetrates through the upper surface of the moving seat 9, the relative height of the adjusting pressing roller 15 can be observed through the scale values 161 on the surface of the sliding bolt 16.

[0027] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special description and limitation.
