[0002] As the name suggests, porous reflective film is a film with numerous tiny pores on its surface or within its interior. These pores impart unique optical reflective properties to the film. Typically, porous reflective film is composed of alternating layers of optical thin films composed of high-refractive and low-refractive materials. Specific optical effects can be achieved by precisely controlling the thickness and refractive index of each layer.

[0003] In the general processing of porous reflective film, when using traditional film cutting equipment for cutting, the reflective film is prone to displacement due to various reasons (such as insufficient machine precision, material characteristics, etc.). This displacement not only leads to reduced cutting efficiency, but also makes the cutting edge uneven, affecting product quality. At the same time, the manual fixing of the reflective film is not only prone to errors, but also greatly increases the manual workload. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] See Figure 1 and Figure 2 As shown, a film cutting device for processing porous reflective film includes an operating table 1, with slides 2 installed on both sides of the upper surface of the operating table 1, and a cutting assembly installed on the slide 2, and a film cloth adsorption assembly installed on the operating table 1, and the film cloth adsorption assembly includes an operating chamber 14 opened by the operating table 1 and located between the two slides 2, and the opening of the operating chamber 14 is upward, and an air suction pump 4 is installed on one side of the operating table 1, and the air suction pump 4 is connected to an air suction pipe 5, and an air outlet pipe 23 is installed on the air suction pump 4 on the other side of the air suction pipe 5, and the other end of the air suction pipe 5 is connected to a first connecting pipe 6, and the side of the first connecting pipe 6 close to the operating chamber 14 is connected to a second connecting pipe 7 that penetrates into the operating chamber 14, and the number of the second connecting pipes 7 is three and is evenly spaced, and a number of evenly spaced air suction pipes 8 are connected above the outer arc wall of the second connecting pipe 7, and an isolation net 18 is provided on the top of the operating chamber 14.

[0025] During the specific implementation process, when the membrane cloth needs to be fixed on the operating table 1 for cutting, the vacuum pump 4 can be started. The vacuum pump 4 extracts the air in the operating chamber 14 through the suction pipe 5, the first connecting pipe 6, the second connecting pipe 7 and the vacuum pipe 8 to form a negative pressure. This negative pressure tightly adsorbs the membrane cloth to the top of the operating chamber 14 under the isolation net 18. At this time, the cutting assembly can start working.

[0026] See Figure 2 As shown, the isolation net 18 is provided with a through hole that matches the cross-sectional diameter of the exhaust pipe 8. The through hole is connected to the top of the exhaust pipe 8. A rubber ring is installed on the top of the through hole. The isolation net 18 is made of carbon fiber composite material. In the specific implementation process, the isolation net 18, as part of the membrane cloth adsorption assembly, can enable the membrane cloth to be stably and evenly adsorbed above the operating chamber 14. The through hole opened on the isolation net 18 not only allows the negative pressure generated by the exhaust pipe 8 to act directly on the membrane cloth, but also ensures the uniform distribution of the negative pressure, thereby improving the adsorption effect of the membrane cloth. A rubber ring is also installed on the top of the through hole. The rubber ring can provide an additional sealing effect to prevent the negative pressure from leaking at the through hole, thereby ensuring that the negative pressure can act on the membrane cloth more effectively. It can also protect the membrane cloth from friction damage at the edge of the through hole, thereby extending the service life of the membrane cloth.

[0027] See Figure 3 As shown, a mounting sleeve 9 is sleeved on the outer arc wall of the second connecting tube 7. The mounting sleeve 9 is located between the first connecting tube 6 and the operating chamber 14. The mounting sleeve 9 is connected to a connecting bar 11 that vertically passes through the mounting sleeve 9 and the second connecting tube 7. The bottom end of the connecting bar 11 is connected to an isolation plug 12. The outer arc wall of the isolation plug 12 is in contact with the inner arc wall of the second connecting tube 7. A swivel 10 is installed on the top of the connecting bar 11, and a gasket 13 is installed on the outer arc wall of the isolation plug 12.

[0028] During the specific implementation process, a damping bearing is installed on the outer arc wall of the connecting strip 11, and the damping bearing allows the connecting strip 11 to rotate smoothly in the mounting sleeve 9. The mounting sleeve 9 provides a mounting point for the rotation of the connecting strip 11. The connecting strip 11 and the isolation plug 12 together constitute an adjustable sealing mechanism, and its outer arc wall fits tightly against the inner arc wall of the first connecting tube 6 to form a sealing surface. By rotating the swivel 10, the connecting strip 11 drives the isolation plug 12 to rotate and adjust the position of the isolation plug 12 in the second connecting tube 7. When the isolation plug 12 rotates until its outer arc wall fits against the inner arc wall of the second connecting tube 7, it can block the air suction in the second connecting tube 7, thereby achieving control of the adsorption range. Conversely, the air suction in the second connecting tube 7 will adsorb the diaphragm through the gap on both sides of the isolation plug 12. The user can flexibly adjust the adsorption area of ​​the diaphragm according to actual needs to achieve the best cutting effect.

[0029] See Figure 1 and Figure 4As shown, the cutting assembly includes a chute defined within a slide 2, to which a slider 15 is slidably connected. One of the sliders 15 is threadedly connected to a threaded rod 16. One end of the threaded rod 16 is rotatably connected to the inner wall of the chute, and the other end is transmission-connected to a servo motor 17. Mounting seats 21 are fixedly connected to the tops of the two sliders 15. The two mounting seats 21 have grooves with openings facing each other. A connecting rod 19 is slidably connected between the two grooves, and a blade 20 is connected to the bottom of the connecting rod 19. In a specific implementation, when a user needs to cut a porous reflective film, the servo motor 17 is started. The servo motor 17 drives the threaded rod 16 to rotate, thereby driving the slider 15 threadedly connected thereto to move within the chute. Since the two sliders 15 move synchronously, they drive the mounting seats 21, connecting rod 19, and blade 20 at their tops to move together.

[0030] See Figure 1 and Figure 4 As shown, a hydraulic rod 22 is mounted in a groove of one mounting seat 21, and a telescopic rod is mounted in another groove. The movable ends of the hydraulic rod 22 and the telescopic rod are fixedly connected to the bottom of the connecting rod 19. A support leg 3 is mounted at the bottom of the operating table 1. In practice, the hydraulic rod 22 provides stable thrust and pressure through its internal hydraulic system, which can accurately control the vertical cutting force of the blade 20. The telescopic range of the hydraulic rod 22 can also be adjusted according to different cutting requirements to accommodate porous reflective films of different thicknesses or materials.

[0031] Working principle:

[0032] Step 1: When the membrane needs to be fixed on the operating table 1 for cutting, the vacuum pump 4 is activated. The vacuum pump 4 extracts the air from the operating chamber 14 through the suction pipe 5, the first connecting pipe 6, the second connecting pipe 7, and the suction pipe 8, creating a negative pressure. This negative pressure tightly adsorbs the membrane to the top of the operating chamber 14 below the isolation net 18. The through-holes in the isolation net 18 allow the negative pressure generated by the suction pipe 8 to act directly on the membrane, ensuring uniform distribution of negative pressure and improving the membrane's adsorption effect. The rubber ring provides an additional sealing effect, preventing negative pressure from leaking through the through-holes and protecting the membrane from friction damage at the edges of the through-holes. By rotating the swivel 10, the connecting strip 11 drives the isolation plug 12 to rotate, adjusting the isolation plug 12's position within the second connecting pipe 7. When the isolation plug 12 rotates until its outer arc wall aligns with the inner arc wall of the second connecting pipe 7, it can block the air inhalation in the second connecting pipe 7, thereby achieving control over the adsorption range. Users can flexibly adjust the membrane's adsorption area according to actual needs to achieve the optimal cutting effect.

[0033] Step 2: Start the servo motor 17. The servo motor 17 drives the threaded rod 16 to rotate, thereby driving the slider 15 threadedly connected to it to move in the slide groove. The two sliders 15 keep moving synchronously, driving the mounting base 21 on their tops, the connecting rod 19 and the blade 20 to move together. The hydraulic rod 22 provides stable thrust and pressure through its internal hydraulic system to accurately control the vertical cutting force of the blade 20. The telescopic range of the hydraulic rod 22 can also be adjusted according to different cutting requirements to adapt to porous reflective films of different thicknesses or materials.
