Description

Technical Field

[0001] The utility model relates to the technical field of matte film preparation equipment, in particular to a sample forming mechanism for preparing a water-resistant matte film. Background Art

[0002] Matte film is a special film material, usually made of polymer or other plastics, with a matte (i.e. non-reflective) surface. It has a different surface treatment than ordinary transparent plastic film, which gives it a matte effect, that is, the surface does not emit light or reflect light. Matte film surface treatment reduces reflection, so it does not produce bright spots or reflections. This makes it very useful in situations where it is necessary to reduce reflections or prevent glare. Prototyping refers to the process of shaping and forming matte film during the manufacturing process, which usually requires a series of processing steps to achieve the desired shape, size and characteristics.

[0003] Since the matte film will have uneven and jagged conditions on both sides during the production process, the matte film needs to be trimmed on both sides after production to facilitate subsequent use. The existing matte film trimming is usually single-sided trimming, which requires cutting and trimming one side before cutting and trimming the other side. This method affects the efficiency of matte film trimming.

[0004] In view of this, we propose a sample forming mechanism for preparing a water-resistant matte film. Utility Model Content

[0024] In the above embodiment, it should be noted that the center of the roller 13 is rotatably connected to the grooved inner wall of the base 11 through a metal rod, the collection box 14 can collect and process the matte film waste after cutting by the cutting component, and the cutting component can trim the matte film passing through the top surface of the roller 13.

[0025] Example 2

[0026] like Figure 2-Figure 4 As shown, a sample forming mechanism for preparing a water-resistant matte film in an embodiment of the first aspect of the utility model includes all the contents of embodiment 1. In addition, the cutting assembly includes a lifting ear 21, and the lifting ear 21 is fixedly installed at the bottom center of the bracket 12. The inner wall of the lifting ear 21 is rotatably connected with a screw 22. Both ends of the screw 22 penetrate the inner wall of the bracket 12 and extend to one side of the outer wall of the bracket 12. A motor 23 is provided on one side of the outer wall of the bracket 12. The output end of the motor 23 is fixedly connected to one end of the screw 22. The threads on both sides of the surface of the screw 22 are arranged in opposite directions.

[0027] In the above embodiment, it should be noted that the screw 22 can be rotatably connected to the inner wall of the ear 21, the surface center of the screw 22 is rotatably connected to the inner wall of the ear 21, and one end of the screw 22 can be driven to rotate by the motor 23, which is a stepping motor.

[0028] Example 3

[0029] like Figure 2-Figure 4 As shown, a sample forming mechanism for preparing a water-resistant matte film in the embodiment of the first aspect of the utility model includes all the contents of embodiment 2. In addition, sliders 31 are provided on both sides of the surface of the screw 22. The slider 31 is in an L-shaped structure. A threaded hole is provided on one side of the surface of the slider 31. The slider 31 is threadedly connected to the screw 22. A support rod 311 is fixedly installed on one side of the bottom surface of the slider 31. A connecting plate 32 is rotatably connected to the side of the support rod 311 away from the slider 31. A cutting wheel 33 is rotatably connected to one end of the connecting plate 32 away from the support rod 311. A first rotating shaft 34 is fixedly connected to the other side of the bottom surface of the slider 31. A hydraulic rod 35 is fixedly installed on the surface of the first rotating shaft 34. The other end of the hydraulic rod 35 is fixedly connected to the second rotating shaft 351. A slider 352 is rotatably connected to the inner wall of the second rotating shaft 351. A sliding groove 321 is provided on the surface of the connecting plate 32. The surface of the slider 352 is slidably connected to the surface of the sliding groove 321.

[0030] In the above embodiment, it should be noted that when the screw 22 rotates, it can drive the sliders 31 on both sides to slide, and the sliders 31 slide along the direction of the screw 22. Since the threads on both sides of the surface of the screw 22 are arranged in opposite directions, the screw 22 can drive the sliders 31 to slide inward or outward at the same time when rotating, thereby adjusting the spacing between the two cutting wheels 33. In the default state, the hydraulic rod 35 is in a retracted state. At this time, the cutting wheel 33 does not contact the surface of the roller 13. When cutting is required, the hydraulic rod 35 can be controlled to retract, so that the cutting wheel 33 is close to the surface of the roller 13, thereby cutting the matte film passing through the surface of the roller 13, and the hydraulic rods 35 on both sides can be controlled separately, so that unilateral or bilateral trimming can be flexibly selected.

[0031] Example 4

[0032] like Figure 2-Figure 4 As shown, a sample forming mechanism for preparing a water-resistant matte film in the embodiment of the first aspect of the utility model includes all the contents of embodiment 3, and in addition, the outer side of one end of the connecting plate 32 close to the cutting wheel 33 is rotatably connected to a support arm 331, one end of the support arm 331 is rotatably connected to a roller 332, and a torsion spring is provided on the inner side of one end of the support arm 331 rotatably connected to the connecting plate 32;

[0033] In the above embodiment, it should be noted that the roller 332 is arranged on the outside of the cutting wheel 33. When the cutting wheel 33 is close to the roller 13, the roller 332 can first contact the matte film. When the cutting wheel 33 cuts the matte film, the roller 332 can push the cut part downward so that the cut part falls into the collection box 14 below. One end of the torsion spring of the support arm 331 is fixedly connected to the support arm 331, and the other end of the torsion spring of the support arm 331 is fixedly connected to the connecting plate 32. When the roller 332 contacts the matte film, it can be buffered to prevent the pressure of the roller 332 from directly acting on the surface of the matte film and causing deformation of the matte film.

[0034] The use process of the utility model is as follows. Those skilled in the art will arrange the device between the production lines of the matte film. When the matte film passes through the surface of the roller 13, the hydraulic rod 35 is extended and retracted to make the cutting wheel 33 close to the surface of the roller 13, thereby cutting the matte film passing through the surface of the roller 13, and the hydraulic rods 35 on both sides can be controlled separately, so that single-sided or double-sided trimming can be flexibly selected. When the cutting wheel 33 cuts the matte film, the roller 332 can push the cut part downward, so that the cut part falls into the collection box 14 below.

[0035] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
