Technical Field

[0001] This utility model relates to the field of film cutting equipment technology, and more specifically, to a film cutting device. Background Technology

[0002] In the production process of lipstick tubes, when the processed lipstick tubes are arranged on trays, a protective film needs to be placed between the stacked trays to prevent the upper trays from scratching the processed lipstick tubes in the lower trays. The existing protective films are all pre-cut by hand before reuse, which is a cumbersome process. Furthermore, the pre-cut protective films may be at risk of attracting dust and causing contamination. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-4 As shown, this embodiment discloses a film cutting device, including a base plate 1, a film stretching assembly 2, a film cutting assembly 3, and a film roll 4. The film stretching assembly 2 and the film cutting assembly 3 are mounted on the upper surface of the base plate 1. The film stretching assembly 2 includes a first slide rail 21 and a first slide frame 22. The first slide frame 22 slides along the first slide rail 21. The first slide frame 22 includes a connecting plate 221, which is perpendicular to the first slide rail 21. The first slide frame 22 is equipped with grippers 23, which can move closer to or further away from the film cutting assembly 3. There are two grippers 23, which are spaced apart along the length of the connecting plate 221. 23 can clamp the diaphragm 41 along the width direction of the diaphragm 41, making the clamping and pulling out of the diaphragm 41 more stable. Each clamp 23 is driven by a cylinder, which is mounted on the connecting plate 221. Each clamp 23 includes two clamping plates 231 arranged vertically. The two clamping plates 231 can move closer or further away from each other. The cylinder drives the two clamping plates 231 to move away from each other, and then the first slide 22 moves closer to the film cutting assembly 3. When the diaphragm 41 is located within the two clamping plates 231, the cylinder drives the two clamping plates 231 to move closer to each other to clamp the diaphragm 41. Then the first slide 22 moves away from the film cutting assembly 3, which can pull out the diaphragm 41.

[0022] The clamping plate 231 includes clamping strips 232, which extend along the length of the clamping plate 231. The clamping strips 232 are located on the end face of the clamping plate 231 facing the other clamping plate 231. The clamping strips 232 are provided with multiple protruding ridges 2321, and a groove 2322 is formed between two adjacent protruding ridges 2321. The protruding ridges 2321 and the grooves 2322 of the two clamping strips 232 are vertically corresponding. The two clamping strips 232 of the two clamping plates 231 facing each other can clamp the diaphragm 41. The diaphragm 41 is clamped by the interlocking characteristics between the protruding ridges 2321 and the grooves 2322, making the clamping of the diaphragm 41 by the two clamping plates 231 more stable.

[0023] The film cutting assembly 3 includes a second slide rail 31 and a second slide 33. The second slide rail 31 is vertically arranged with the first slide rail 21 in the horizontal direction. The second slide 33 can slide along the second slide rail 31. The second slide rail 31 has a channel for the film sheet 41 to pass through. The film roll 4 is located on the side of the film cutting assembly 3 away from the film stretching assembly 2. The side of the second slide rail 31 near the film roll 4 is provided with a tensioning roller. The film sheet 41 of the film roll 4 can pass through the second slide rail 31. The second slide 33 is provided with a film exit plate 32. The film exit plate 32 is located on the side of the second slide 33 facing the gripper 23. The film exit plate 32 includes two plates 321. 21 is located above and below the channel opening of the second slide rail 31. The diaphragm 41 is located between the two plates 321. The diaphragm 41 passes through the two plates 321. The plates 321 include a protrusion 3211. Notches are formed on both sides of the protrusion 3211. The two notches can accommodate two grippers 23 respectively. When the blade 331 cuts the pulled-out diaphragm 41, it will cut along the outer edge of the protrusion 3211. Therefore, the diaphragm 41 will be exposed in the notch. The two grippers 23 can just enter the two notches to clamp the diaphragm 41 in the notch, so that the grippers 23 can clamp and pull out the diaphragm 41.

[0024] The second slide 33 is equipped with a blade 331, which can cut the diaphragm 41 along the length of the second slide rail 31. The second slide 33 includes a sliding frame 332, which can slide along the second slide rail 31. The blade 331 is slidably mounted on the sliding frame 332. The movement of the second slide 33 can drive the blade 331 to cut the diaphragm 41. The blade 331 can move up and down by a cylinder, so that the blade 331 can cut the diaphragm 41 up and down while moving along the second slide rail 31, which can better cut the diaphragm 41 and prevent it from not being cut. The sliding frame 332 can increase the stroke distance of the blade 331 at the end point, so that the blade 331 can completely cut the diaphragm 41.

[0025] Two support frames 11 are installed on the upper surface of the base plate 1. The two support frames 11 are located on both sides of the first slide rail 21. The support frames 11 extend along the length of the first slide rail 21. The upper surface of the support frame 11 supports the diaphragm 41. The two support frames 11 can support the two sides of the diaphragm 41 when the diaphragm 41 is pulled out. At the same time, the upper surface of the first slide rail 21 can also play a supporting role to prevent the diaphragm 41 from sinking downward.

[0026] Two first cylinders 12 are installed on the base plate 1. The first cylinders 12 drive the first pressure plate 13 to approach or move away from the upper end face of the support frame 11. The diaphragm 41 can pass between the first pressure plate 13 and the support frame 11. When the first cylinders 12 drive the first pressure plate 13 to pull the diaphragm 41 out to the initial position of the gripper 23, the first pressure plate 13 presses the edge of the diaphragm 41.

[0027] Two second cylinders 14 are mounted on the upper surface of the base plate 1. Two third pressure plates 34 are mounted on the second slide rail 31. The two third pressure plates 34 are located at both ends of the diaphragm plate 32. The second cylinders 14 are equipped with second pressure plates 15. The second pressure plates 15 can move closer to or further away from the third pressure plates 34. The diaphragm 41 can pass between the second pressure plates 15 and the third pressure plates 34. The second cylinders 14 can drive the second pressure plates 15. When the gripper 23 pulls the diaphragm 41 out to the initial position of the gripper 23, the second pressure plates 15 and the third pressure plates 34 press the edge of the diaphragm 41 tightly. The first pressure plate 13 presses the diaphragm 41, and the second and third pressure plates 15 and 34 press the diaphragm 41 to fix the diaphragm 41 at the starting and ending points of the cutting by the blade 331. This allows the blade 331 to better advance and retract, and prevents wrinkles from appearing on the edge of the diaphragm 41 due to the cutting by the blade 331. After the cutting is completed, the first pressure plate 13 releases the diaphragm 41, and the second pressure plate 15 releases the diaphragm 41. The cut diaphragm 41 is then transferred by an external suction cup, and can be cut again after the diaphragm 41 is transferred.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
