Technical Field

[0001] This application relates to the field of film cutting, and in particular to a film cutting apparatus. Background Technology

[0002] Aluminum foil (including hot-melt self-adhesive aluminum foil) is a thin sheet made of aluminum metal through processes such as rolling. It usually has high ductility and thermal conductivity and can be used for various purposes such as packaging, heat insulation, and electrical conductivity.

[0003] Aluminum foil is usually rolled on the outer surface of a spool. When in use, the metal film on the spool is pulled to the required length, and then the aluminum foil is cut with a cutter. This cutting method has many problems. For example, there is no specific tool to fix the spool, it is inconvenient for the user to pull the metal film, sometimes there are small wrinkles on the metal film that need to be smoothed manually, and when cutting the film, it is also necessary to find the cutter, which affects the cutting efficiency. Therefore, a cutting device is needed to cut aluminum foil. Utility Model Content

[0004] The film cutting device provided in this application fixes the roll in a simple way, and smooths out small wrinkles on the film during the pulling process, improving the practicality of the device and facilitating the cutting of the film, thereby increasing the cutting efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: a film cutting device, the device comprising:

[0006] frame;

[0007] A rotating rod is mounted on one side of the frame via a bearing, and a first fixing plate is fixedly sleeved on the outer surface of the rotating rod. The rotating rod can rotate via the bearing.

[0008] A rotating drum is threaded onto the outer surface of the first fixed plate, and a second fixed plate is fixedly installed on one side of the rotating drum. When the rotating rod cannot rotate, the rotating drum is rotated counterclockwise to drive the second fixed plate to rotate and remove the second fixed plate from the rotating rod.

[0009] Pressure bars are fixedly installed on both sides of the frame;

[0010] Multiple first sleeve rods are fixedly installed on the inner side of one side of the frame, and a second sleeve rod is movably embedded on one side of each of the multiple first sleeve rods.

[0011] As a further improvement of this application: the second fixing plate is movably sleeved on the outer surface of the rotating rod, and a first handle is fixedly provided on one side of the rotating rod.

[0012] As a further improvement of this application: a protruding plate is fixedly provided on one side of each of the plurality of second sleeve rods, and a spring is movably sleeved on the outer surface of each of the plurality of second sleeve rods. A second pressure roller is movably provided on the inner wall of the protruding plate, and a first pressure roller is movably provided on both sides of the inner wall of the frame. The first and second pressure rollers can rotate. During the process of cutting and pulling the film, the film is smoothed out by the squeezing of the second and first pressure rollers.

[0013] As a further improvement of this application: a bidirectional lead screw is provided on both sides of the inner wall of the frame via bearings. Two sleeves are threaded on the outer surface of the bidirectional lead screw. The two sleeves are slidably disposed on one side of the inner wall of the frame. There are two threaded grooves with different directions of rotation on the outer surface of the bidirectional lead screw. The two sleeves are respectively connected to the two threaded grooves with different directions of rotation. The two sleeves can slide on one side of the inner wall of the frame. Thus, when the bidirectional lead screw rotates in different directions, the two sleeves move in relative or opposite directions on their outer surfaces.

[0014] As a further improvement of this application: a transmission rod is movably provided on the inner wall of each of the two sleeves, a pressure plate is movably provided on one side of each of the two transmission rods, a second handle is fixedly provided on one side of the bidirectional screw, the two transmission rods can rotate about the connection point of the two sleeves as an axis, and the two transmission rods can rotate about the connection point of the pressure plate as an axis.

[0015] As a further improvement of this application: a connecting rod is fixedly provided on one side of the frame, and a mounting plate is movably sleeved on the outer surface of the connecting rod, the mounting plate being rotatable about the connecting rod.

[0016] As a further improvement of this application: a cutting blade is installed on one side of the connecting rod, and a cylinder is fixedly installed on one side of the connecting rod. The cylinder drives the mounting plate to rotate, so that the cutting edge on the cutting blade cuts the film surface. A turntable is fixedly installed, and a groove is opened on the outer surface of the rotating rod. Rotating the turntable drives the threaded rod to rotate.

[0017] As a further improvement of this application: an arc-shaped plate is fixedly provided on one side of the frame, and the cylinder is placed on the arc-shaped plate when the film is not being cut.

[0018] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0019] 1. In this application, during the cutting of aluminum film, the second fixing plate can slide on the outer surface of the rotating rod. The rotating rod can rotate through the bearing. When the user holds the first handle with one hand, the rotating rod cannot rotate. Then, the rotating drum is rotated counterclockwise to drive the second fixing plate to rotate and remove the second fixing plate from the rotating rod. At this time, the roll of film is placed on the outer surface of the rotating rod, with one side tightly against the side of the first fixing plate. Then, the second fixing plate is placed on the outer surface of the rotating rod, and the rotating drum is rotated clockwise to drive the second fixing plate to the side of the first fixing plate. When the rotating drum is difficult to rotate, the first fixing plate and the second fixing plate fix the roll. At this time, the first handle is released and the roll can rotate with the rotating rod. When using the device, the roll is fixed, and the method of fixing the roll is relatively simple.

[0020] 2. In this application, one side of the film is pulled so that it adheres to the outer surface of the pressure rod. Multiple second rods can slide on the inner walls of multiple first rods. By pushing the convex plate upward, the multiple second rods slide to the inner walls of the multiple first rods, squeezing multiple springs and forcing the film through the gap between the first and second pressure rollers. Releasing the convex plate, the elastic force generated by the multiple springs pushes the convex plate, causing the second and first pressure rollers to clamp the film on both sides. During the process of pulling the film using the cutting device, the squeezing of the film by the second and first pressure rollers smooths out the fine wrinkles on the film, improving the practicality of the device.

[0021] 3. In this application, the pressure plate is pressed onto the film surface by turning the second handle counterclockwise. The mounting plate can rotate around the connecting rod as an axis. The cylinder drives the mounting plate to rotate, so that the cutting edge on the cutting blade cuts the film surface and cuts the film. When not cutting the film, the cylinder is placed on the arc plate to complete the film cutting, thereby facilitating the film cutting and improving the cutting efficiency.

[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0032] Example 1, such as Figures 1 to 7 As shown, this application provides a film cutting apparatus, which includes:

[0033] Rack 1;

[0034] The rotating rod 2 is mounted on one side of the frame 1 via a bearing, and the outer surface of the rotating rod 2 is fixedly fitted with a first fixing plate 201. The rotating rod 2 can rotate via the bearing.

[0035] The rotating drum 203 is threaded onto the outer surface of the first fixed plate 201, and a second fixed plate 202 is fixedly installed on one side of the rotating drum 203. When the rotating rod 2 cannot rotate, the rotating drum 203 is rotated counterclockwise to drive the second fixed plate 202 to rotate, and the second fixed plate 202 is removed from the rotating rod 2.

[0036] Pressure bars 205 are fixedly installed on both sides of the frame 1;

[0037] Multiple first sleeve rods 207 are fixedly installed on the inner side of one side of the frame 1, and a second sleeve rod 208 is movably embedded on one side of each of the multiple first sleeve rods 207.

[0038] like Figures 1 to 7 As shown, the second fixing plate 202 is movably sleeved on the outer surface of the rotating rod 2, and a first handle 204 is fixedly installed on one side of the rotating rod 2.

[0039] like Figures 1 to 7 As shown, a protruding plate 209 is fixedly provided on one side of each of the multiple second sleeve rods 208, and a spring 210 is movably sleeved on the outer surface of each of the multiple second sleeve rods 208. A second pressure roller 211 is movably provided on the inner wall of the protruding plate 209, and a first pressure roller 206 is movably provided on both sides of the inner wall of the frame 1. The first pressure roller 206 and the second pressure roller 211 can rotate. During the process of cutting and pulling the film, the film is smoothed out by the pressure of the second pressure roller 211 and the first pressure roller 206.

[0040] like Figures 1 to 7 As shown, a bidirectional lead screw 3 is provided on both sides of the inner wall of the frame 1 via bearings. Two sleeves 301 are threaded on the outer surface of the bidirectional lead screw 3. The two sleeves 301 are slidably disposed on one side of the inner wall of the frame 1. There are two threaded grooves with different directions of rotation on the outer surface of the bidirectional lead screw 3. The two sleeves 301 are respectively connected to the two threaded grooves with different directions of rotation, and the two sleeves 301 can slide on one side of the inner wall of the frame 1. Thus, when the bidirectional lead screw 3 rotates in different directions, the two sleeves 301 move in relative or opposite directions on their outer surfaces.

[0041] like Figures 1 to 7 As shown, a transmission rod 302 is movably installed on the inner wall of each of the two sleeves 301. A pressure plate 303 is movably installed on one side of each of the two transmission rods 302. A second handle 304 is fixedly installed on one side of the bidirectional lead screw 3. The two transmission rods 302 can rotate about the connection point of the two sleeves 301 as an axis, and the two transmission rods 302 can also rotate about the connection point of the pressure plate 303 as an axis.

[0042] like Figures 1 to 7 As shown, a connecting rod 305 is fixedly installed on one side of the frame 1, and a mounting plate 306 is movably sleeved on the outer surface of the connecting rod 305. The mounting plate 306 can rotate about the connecting rod 305.

[0043] like Figures 1 to 7 As shown, a cutting blade 307 is installed on one side of the connecting rod 305, and a cylinder 308 is fixedly installed on one side of the connecting rod 305. The cylinder 308 drives the mounting plate 306 to rotate, so that the cutting edge on the cutting blade 307 cuts on the film surface.

[0044] like Figures 1 to 7 As shown, an arc plate 309 is fixedly installed on one side of the frame 1. When not cutting the film, the cylinder 308 is placed on the arc plate 309.

[0045] Working principle: When cutting aluminum foil, the second fixing plate 202 can slide on the outer surface of the rotating rod 2. The rotating rod 2 can rotate through the bearing. When the user holds the first handle 204 with one hand, the rotating rod 2 cannot rotate. Then, the rotating drum 203 is rotated counterclockwise to drive the second fixing plate 202 to rotate, and the second fixing plate 202 is removed from the rotating rod 2. At this time, the roll of film is placed on the outer surface of the rotating rod 2, so that one side is tightly against the side of the first fixing plate 201. Then, the second fixing plate 202 is placed on the outer surface of the rotating rod 2. The rotating drum 203 is rotated clockwise to drive the second fixing plate 202 to the side of the first fixing plate 201. When the rotating drum 203 is difficult to rotate, the first fixing plate 201 and the second fixing plate 202 move towards the side of the first fixing plate 201. 02. Fix the roll. At this time, release the first handle 204 so that the roll can rotate with the rotating rod 2. When using the device, fix the roll. The fixing method of the roll is relatively simple. Pull one side of the film so that one side is attached to the outer surface of the pressure rod 205. Multiple second sleeve rods 208 can slide on the inner wall of multiple first sleeve rods 207 respectively. By pushing the convex plate 209 upward, the multiple second sleeve rods 208 slide to the inner wall of multiple first sleeve rods 207, squeezing multiple springs 210, and passing the film through the gap between the first pressure roller 206 and the second pressure roller 211. Release the convex plate 209. The elastic force generated by the multiple springs 210 pushes the convex plate 209, so that the second pressure roller 211 and the first pressure roller 206 are clamped on both sides of the film. Figure 6 As shown, the outer surface of the bidirectional lead screw 3 has two threaded grooves with different helical directions. Two sleeves 301 are connected to these two grooves respectively, and the two sleeves 301 can slide on one side of the inner wall of the frame 1. Therefore, when the bidirectional lead screw 3 rotates in different directions, the two sleeves 301 move relative to or in opposite directions on their outer surfaces. The two transmission rods 302 can rotate about the connection point of the two sleeves 301, and also about the connection point of the pressure plate 303. Thus, when the two sleeves 301 move relative to each other, the two transmission rods 302 pull the pressure plate 303 upwards; when the two sleeves 301 move in opposite directions, they push the pressure plate 303 downwards. When the second handle 304 is turned clockwise, the bidirectional lead screw 3 rotates, causing the two sleeves 301 to move in opposite directions. This causes the pressure plate 303 to move upward, allowing the film to pass through the gap between the pressure plate 303 and the inner wall of the frame 1. The zero-mark side of the measuring ruler is then pressed against one side of the pressure plate 303. At this point, the film is pulled, allowing the first pressure roller 206 and the second pressure roller 211 to rotate. During the film pulling process, the pressure of the second pressure roller 211 and the first pressure roller 206 smooths out small wrinkles on the film, improving the practicality of the device. When the film is pulled to the required length, the second handle 304 is turned counterclockwise, causing the pressure plate 303 to press against the film surface. Figure 5As shown, the mounting plate 306 can rotate around the connecting rod 305. The cylinder 308 drives the mounting plate 306 to rotate, so that the cutting edge on the cutting blade 307 cuts the film surface and cuts the film. When not cutting the film, the cylinder 308 is placed on the arc plate 309 to complete the cutting of the film, thereby facilitating the cutting of the film and improving the cutting efficiency.

[0046] The above are merely preferred embodiments and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
