Cutting is a crucial step in the production of screen protectors. The quality and performance of the cutting equipment directly affect the dimensional accuracy, edge quality, and production efficiency of the screen protector.

[0003] Currently, traditional cutting methods, such as manual cutting or using simple cutting tools, are no longer sufficient to meet the needs of large-scale production. Therefore, it is necessary to adopt automated machines. However, some current cutting machines cannot secure the protective film during cutting, and cannot automatically collect the cut film after cutting, thus affecting their usability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutting device for screen protector processing, which aims to improve the problems of existing technology that cannot fix the protective film during cutting and cannot automatically collect it after cutting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screen protector film processing cutting device includes a machine body, a linear guide rail fixedly connected to the top of the machine body, a cutting blade provided at the output end of the linear guide rail, a pressure roller provided inside the machine body, a base fixedly connected to the bottom of the machine body, a secondary clamping plate slidably connected to the top of the base, a clamping assembly fixedly connected inside the base, and collecting assemblies fixedly connected to both the left and right sides of the base.

[0007] The collection assembly includes two protective shells fixedly connected to the left and right sides of the rear of the base. Each of the left and right sides of the rear of the base is fixedly connected with a lock hole. A baffle is slidably connected inside the protective shell. A spring is fixedly connected to the bottom of the baffle. A pin is sleeved inside the spring.

[0008] As a further description of the above technical solution:

[0009] The clamping assembly includes a bottom bracket fixedly connected inside the base. Slide rails are fixedly connected to the top four sides of the bottom bracket. Clamping plates are slidably connected to the top of two adjacent slide rails. Two electric push rods are fixedly connected to the top of the bottom bracket. A latch is fixedly connected to the output end of the electric push rod. The latch is fixedly connected to the outer wall of the clamping plate. A shaft is fixedly connected to the middle of the clamping plate. A connecting rod is rotatably connected to the outside of the shaft. A rotating rod is rotatably connected to the side of the connecting rod away from the shaft.

[0010] As a further description of the above technical solution:

[0011] The pin is slidably connected to the inside of the lock hole, and the bottom of the spring is fixedly connected to the bottom wall of the inner shell.

[0012] As a further description of the above technical solution:

[0013] A roller is slidably connected to the rear of the machine body, and the baffle is slidably connected inside the protective shell.

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by placing the protective film on the base, an electric push rod inside the base drives the right clamping plate to move to the left, simultaneously moving the connecting rod connected to the right clamping plate, which in turn drives the rotating rod to rotate to the left. At this time, the rotating rod drives the left connecting rod to move, and then drives the left clamping plate to move to the right. When the left and right clamping plates retract inward, the auxiliary clamping plate connected to the clamping plates by the support column also retracts inward, achieving the effect of restricting the protective film.

[0024] 2. In this utility model, the cut protective film falls into the loading box after passing through the roller. The loading box is fixed to the base by the collecting component. When the loading box is fixed to the base, the slide rail can prevent the loading box from being unable to be fixed due to the pin falling down.

The collection assembly includes two protective shells 17 fixedly connected to the left and right sides of the rear of the base 4. The protective shells 17 can prevent damage to the internal structure. Lock holes 9 are fixedly connected to the left and right sides of the rear of the base 4. A baffle 19 is slidably connected inside the protective shell 17. A spring 20 is fixedly connected to the bottom of the baffle 19. A pin 18 is sleeved inside the spring 20. When the pin 5 is not pulled, the baffle 19 fixed to the pin 5 will prevent the pin 5 from falling.

[0035] Reference Figure 3 and Figure 4 The clamping assembly includes a bottom bracket 10 fixedly connected inside the base 4. Slide rails 11 are fixedly connected to the top of the bottom bracket 10 around its perimeter. Clamping plates 22 are slidably connected to the top of two adjacent slide rails 11. Two electric push rods 14 are fixedly connected to the top of the bottom bracket 10. The output end of the electric push rods 14 drives the clamping plates 22 to move on the slide rails 11. A latch 13 is fixedly connected to the output end of the electric push rods 14. The latch 13 is fixedly connected to the outer wall of the clamping plates 22 to fix the output end of the electric push rods 14 to the clamping plates 22. A shaft 12 is fixedly connected to the middle of the clamping plates 22. A connecting rod 15 is rotatably connected to the outside of the shaft 12. A rotating rod 16 is rotatably connected to the side of the connecting rod 15 away from the shaft 12. The movement of the clamping plates 22 will drive the connecting rod 15 to move, thereby driving the rotating rod 16 to rotate, and thus driving the clamping plates 22 to move.

[0036] Reference Figure 5 The pin 18 is slidably connected to the inside of the lock hole 9. The pin 18 can be fixed together with the lock hole 9, or it can be pulled to separate from the lock hole 9. The bottom of the spring 20 is fixedly connected to the inner bottom wall of the protective shell 17.

[0037] Reference Figure 2 and Figure 5Rollers 7 are slidably connected to the rear of the machine body 1. After the protective film is cut, it will be conveyed to the loading box 8 through rollers 7. Baffle 19 is slidably connected inside the protective shell 17.

[0038] Reference Figure 2 and Figure 6 A material box 8 is fixedly connected to the outside of the protective shell 17 to collect the protective film after cutting. The material box 8 is slidably connected between two slide rails 11, which can be used to prevent the material box 8 from falling downward when it is fixed.

[0039] Reference Figure 4 The bottom of the secondary clamping plate 3 is fixedly connected to a support column 21, which is fixedly connected to the top of the clamping plate 22. The support column 21 is used to connect the clamping plate 22 and the secondary clamping plate 3, so as to achieve the effect of the clamping plate 22 and the secondary clamping plate moving together.

[0040] Reference Figure 4 and Figure 5 The support column 21 is slidably connected to the top of the base 4. The clamping plate 22 and the auxiliary clamping plate 3 are fixed together by the support column 21. When the clamping plate 22 moves, the support column 21 will simultaneously drive the auxiliary clamping plate 3 to move. The pin 18 is slidably connected to the inside of the protective shell 17.

[0041] Reference Figure 2 and Figure 3 The rotating rod 16 is rotatably connected to the top of the bottom bracket 10, and the two slide rails 11 are fixedly connected to the bottom rear of the machine body 1. The slide rails 11 can prevent the loading box 8 from falling downward when it is in a fixed state, and can also move the loading box 8 more easily.

[0042] Working principle: First, the protective film to be cut is placed on the base 4, and then the protective film is conveyed by the pressure roller 6. Inside the base, there is a clamping assembly. When the output end of the electric push rod 14 drives the right clamping plate 22 to move to the right on the slide rail 11, the right clamping plate 22 will drive the right connecting rod 15 to move to the right, causing the rotating rod 16 connected to one end of the right connecting rod 15 to rotate to the right. At the same time, the rotating rod 16 connected to one end of the left connecting rod 15 will rotate to the left, thereby causing the left connecting rod 15 to push the left clamping plate 22 to move to the left. When the output end of the electric push rod 14 drives the right clamping plate 22 to move to the left on the slide rail 11, the right clamping plate 22 will drive the right connecting rod 15 to move to the left, causing the rotating rod 16 connected to one end of the right connecting rod 15 to rotate to the left. At the same time, the rotating rod 16 connected to one end of the left connecting rod 15 will rotate to the right, thereby causing the left connecting rod 15 to drive the left clamping plate 22 to move to the right. At this time, the clamping plate 22 and the auxiliary clamping plate 3 are fixedly connected together by the support column 21. When the two clamping plates 22 move outward together, the two auxiliary clamping plates 3 will move outward together through the support column 21, thereby achieving the effect of loosening. When the two clamping plates 22 move inward together, the two auxiliary clamping plates 3 will move inward together through the support column 21, thereby achieving the effect of restricting the protective film.

[0043] After cutting, the clamping roller 6 moves the protective film backward and then conveys it to the loading box 8 via the roller 7. The loading box 8 is fixed to the base 4 by a collecting assembly. Inside the collecting assembly, a baffle 19 is set on the top of the spring 20 and fixed to the pin 18. When the pin 18 tries to slide down, the baffle 19 on the top of the spring 20 prevents the pin 18 from falling down, thus fixing it in place. Locking holes 9 are provided on both the left and right sides of the base 4, allowing it to be engaged with or disengaged from the pin 18. When the loading box 8 is fixed to the base 4, the slide rail 11 connected to the loading box 8 effectively prevents the loading box 8 from falling down. When the pin 18 is pulled down, the loading box 8 can be pulled up via the slide rail 11, allowing it to be removed for easy material retrieval.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
