Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, in particular to a cutting device for producing a single-layer silicone protective film. Background Art

[0002] Silicone protective film is a screen protective film mainly used to protect electronic products. The current mainstream silicone protective film is PET silicone screen protective film, which is suitable for mobile phones, computers, various screen display surface protection masks, mirrors, etc., surface anti-scratch, dustproof, radiation-proof and other protective masks. This protective film uses a unique imported environmentally friendly electrostatic adsorption silicone layer technology to ensure that the screen of electronic products is fully protected by the silicone protective film.

[0003] Although there are many cutting devices for producing single-layer silicone protective film on the market nowadays, most of these devices can only cut the silicone protective film into multiple sections or can only cut the silicone protective film when winding. If the silicone protective film needs to be cut into multiple sections or the silicone protective film needs to be cut, it is necessary to move to other cutting devices, which is time-consuming and labor-intensive to use, reduces the production efficiency of the silicone protective film, and makes the application range of the equipment smaller. In addition, when the general cutting device cuts the silicone protective film, the silicone protective film is in a relatively loose state, which may cause shaking when the silicone protective film is cut, resulting in inaccurate cutting or burrs, which requires further cutting afterwards, thereby affecting the production efficiency of the silicone protective film and causing waste of resources. In order to solve the above problems, a cutting device for producing a single-layer silicone protective film is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that although there are many cutting devices for producing single-layer silicone protective films on the market nowadays, most of these devices can only cut the silicone protective film into multiple sections or can only cut the silicone protective film when winding. If the silicone protective film needs to be cut into multiple sections or the silicone protective film needs to be cut, it is necessary to move to other cutting devices, which is time-consuming and labor-intensive to use, reduces the production efficiency of the silicone protective film, and makes the application range of the equipment smaller. When the general cutting device cuts the silicone protective film, the silicone protective film is in a relatively loose state, which may cause shaking when the silicone protective film is cut, resulting in inaccurate cutting or burrs, so that it needs to be cut again afterwards, thereby affecting the production efficiency of the silicone protective film and causing waste of resources. A cutting device for producing a single-layer silicone protective film is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cutting device for producing a single-layer silicone protective film, comprising a mounting base, a fixing frame is fixedly mounted on the top surface of the mounting base, a first supporting frame is fixedly mounted on the top surface of the mounting base, a second supporting frame is fixedly mounted on the top surface of the mounting base, the mounting base is slidably connected to a sliding frame through a sliding groove arranged inside the mounting base, a driven roller is rotatably connected to one side surface of the fixed frame, a rotating roller is rotatably connected to one side surface of the sliding frame, the sliding frame 1 is fixed to the mounting base 3 by a latch, a cutting component is arranged inside the first supporting frame, and a fixing component is arranged inside the second supporting frame.

[0006] As a further description of the above technical solution:

[0007] The fixing assembly includes a driven rod, the second support frame is rotatably connected to the driven rod, a driving bevel gear is fixedly installed on the outer wall of the driven rod, a second telescopic rod is fixedly installed on the bottom surface of the second support frame, and a mounting frame is fixedly installed on the bottom end of the second telescopic rod.

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

[0009] Protective cotton is fixedly installed on the bottom of the mounting frame, and a mounting tube is fixedly installed on the top surface of the mounting frame. The mounting tube is threadedly connected with a threaded rod through a threaded hole arranged inside the mounting tube, and a driven bevel gear is fixedly installed on the top of the threaded rod. The driven bevel gear is located inside the second support frame, and the driven bevel gear and the driving bevel gear are meshed and connected with each other.

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

[0011] The cutting assembly includes a motor, a motor is fixedly mounted on one side surface of the first support frame, a reciprocating screw is fixedly mounted on one end of the output shaft of the motor, the first support frame is slidably connected to a slider via a sliding groove arranged inside the first support frame, the slider is threadedly connected to the reciprocating screw via a threaded hole arranged inside the slider, a rotating disk is rotatably connected to the bottom surface of the slider, and a spring pin is arranged inside the rotating disk.

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

[0013] The slider is slidably connected with a spring pin through a through hole arranged inside it, a first telescopic rod is fixedly installed on the bottom end of the rotating disk, an electric push rod is fixedly installed on the bottom end of the rotating disk, a carrying disk is fixedly installed on the bottom ends of the electric push rod and the first telescopic rod, a cutting machine is fixedly installed on the bottom end of the carrying disk, and a belt is slidably connected to the outer wall of the output shaft of the motor.

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

[0015] A driven rod is slidably connected to the inner wall of the other end of the belt, a fixed plate is fixedly installed at one end of the output shaft of the cutting machine, and a blade is fixedly installed at one end of the fixed plate by bolts.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] In the utility model, by providing a cutting component and a fixing component, when the equipment is used, if the silicone protective film needs to be cut during winding, the motor can be started, and the belt starts to move when the motor is started, and the movement of the belt causes the driven rod to start rotating, and the rotation of the driven rod causes the driving bevel gear to start rotating, and the rotation of the driving bevel gear causes the driven bevel gear to start rotating, and the rotation of the driven bevel gear drives the rotation of the threaded rod, at which time the mounting tube starts to move, and the second telescopic rod also telescopes accordingly, and at the same time the mounting frame and the protective cotton also move accordingly and fix the silicone protective film, and the reciprocating screw starts to rotate due to the starting of the motor, and the reciprocating screw starts to rotate. The rotation of the lever causes the slider to start moving, and the movement of the slider drives the movement of the rotating disk, the electric push rod, the carrier disk and the cutting machine. When the fixing assembly fixes the silicone protective film, the slider is moved to the corner and the motor is turned off. Then the cutting machine is started to rotate the fixed disk and the blade, and then the electric push rod is started to move the carrier disk and the cutting machine downward, and the first telescopic rod is also extended and retracted. When the cutting machine moves to a suitable position, the motor is started. At this time, the movement of the slider drives the movement of the cutting machine and cuts off the silicone protective film. When the silicone protective film needs to be cut into multiple sections, the rotating disk needs to be rotated so that the cutting machine faces a suitable direction, and After determining the direction, the rotating disk is kept fixed by the spring pin, and then the pin on the sliding frame is pulled out, and the sliding frame is moved according to the size of the silicone protective film after winding. When the silicone protective film moves to the bottom of the blade, the pin is inserted to fix the sliding frame and rotate the rotating roller, and then the electric push rod and the motor can be started to change the position of the cutting machine. Through this design, not only the function of cutting and cutting the wound silicone protective film into multiple sections on the same cutting device is realized, but also the function of keeping the silicone protective film fixed when cutting it is avoided because most of these devices can only cut the silicone protective film into multiple sections when winding. Or only the silicone protective film can be cut. When the silicone protective film needs to be cut into multiple sections or the silicone protective film needs to be cut, it needs to be moved to other cutting devices, thereby improving the production efficiency of the silicone protective film. At the same time, it also avoids the situation that the silicone protective film is in a relatively loose state when the general cutting device cuts the silicone protective film, causing the equipment to shake when cutting the silicone protective film, resulting in inaccurate cutting or burrs, which requires further cutting, thereby affecting the production efficiency of the silicone protective film and causing waste of resources. The device is simple and convenient to use and has strong practicality.

[0018] In the utility model, a blade that is easy to replace is provided. During the use of the device, the bolts on the fixed plate can be turned out to separate the blade from the fixed plate and then replaced, thereby avoiding the blade from being worn out due to long-term use, making the blade no longer sharp. If the blade is more troublesome to replace, it will affect the cutting efficiency of the cutting device, thereby affecting the subsequent processes of the silicone protective film. At the same time, the appropriate blade can be replaced according to the size of the silicone protective film, further expanding the scope of application of the device. The device is simple and convenient to use and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific implementation method is as follows: when the equipment is used, if the silicone protective film needs to be cut during winding, the motor 71 can be started. When the motor 71 is started, the belt 72 starts to move. The movement of the belt 72 causes the driven rod 81 to start rotating. The rotation of the driven rod 81 causes the driving bevel gear 87 to start rotating. The rotation of the driving bevel gear 87 causes the driven bevel gear 85 to start rotating. The rotation of the driven bevel gear 85 drives the rotation of the threaded rod 86. At this time, the mounting tube 84 starts to move, and the second telescopic rod 82 also extends and retracts accordingly.

The movement of the slider 74 drives the movement of the rotating disk 75, the electric push rod 77, the carrying disk 711 and the cutting machine 710. When the fixing component 8 fixes the silicone protective film, the slider 74 moves When the cutter 710 is moved to a suitable position, the motor 71 is started, and the slider 74 moves to drive the cutter 710 to move and cut the silicone protective film. When the silicone protective film needs to be cut into multiple sections, the rotating disk 75 needs to be rotated to make the direction facing the cutter 710 suitable, and the rotating disk 75 is kept fixed by the spring pin after the direction is determined, and then the latch on the sliding frame 1 is pulled out, and the sliding frame 1 is moved according to the size of the silicone protective film after being rolled up, and when the silicone protective film moves to the bottom of the blade 78, the latch is inserted to fix the sliding frame 1 and rotate the rotating roller 2, and then the electric push rod 77 and the motor 71 can be started to change the position of the cutter 710;

At the same time, the appropriate blade 78 can be replaced according to the size of the silicone protective film to further expand the scope of application of the device.

[0031] Working principle: When the device is used, if the silicone protective film needs to be cut during winding, the motor 71 can be started. When the motor 71 is started, the belt 72 starts to move. The movement of the belt 72 causes the driven rod 81 to start rotating. The rotation of the driven rod 81 causes the driving bevel gear 87 to start rotating. The rotation of the driving bevel gear 87 causes the driven bevel gear 85 to start rotating. The rotation of the driven bevel gear 85 drives the rotation of the threaded rod 86. At this time, the mounting tube 84 starts to move, and the second telescopic rod 82 also telescopes accordingly. At the same time, the mounting frame 83 and the protective cotton 88 also move accordingly and cut the silicone protective film. The reciprocating screw 73 starts to rotate due to the start of the motor 71, and the rotation of the reciprocating screw 73 causes the slider 74 to move. The movement of the slider 74 drives the movement of the rotating disk 75, the electric push rod 77, the carrier disk 711 and the cutter 710. After the fixing component 8 fixes the silicone protective film, the slider 74 is moved to the corner and the motor 71 is turned off.

When the cutter 710 When the sliding plate 74 moves to a suitable position, the motor 71 is started. At this time, the slider 74 moves to drive the cutting machine 710 to move and cut the silicone protective film. When the silicone protective film needs to be cut into multiple sections, the rotating disk 75 needs to be rotated to make the direction of the cutting machine 710 face the appropriate direction. After determining the direction, the rotating disk 75 is kept fixed by the spring pin, and then the latch on the sliding frame 1 is pulled out. The sliding frame 1 is moved according to the size of the silicone protective film after winding. When the silicone protective film moves to the bottom of the blade 78, the latch is inserted to fix the sliding frame 1 and rotate the rotating roller 2. Then the motor can be started. The push rod 77 and the motor 71 are used to change the position of the cutting machine 710. During the use of the device, the bolts on the fixed plate 79 can be turned out to separate the blade 78 from the fixed plate 79 and then replaced. This avoids the blade 78 from being worn out due to long-term use, making the blade 78 no longer sharp. If it is troublesome to replace the blade 78, it will affect the cutting efficiency of the cutting device, thereby affecting the subsequent processes of the silicone protective film. At the same time, the appropriate blade 78 can be replaced according to the size of the silicone protective film to further expand the scope of application of the device.
