Description

Technical Field

[0001] This utility model relates to the field of film label processing technology, and in particular to a film label laser slitting device. Background Technology

[0002] Film labels are generally made of PET material. PET labels can withstand high temperatures, resist harsh environments, and resist acid and alkali corrosion. They are suitable for outdoor and high-quality labels. Before printing film labels, a slitting machine is needed to cut the roll of PET film to the specified width.

[0003] Traditional film slitting machines typically cut films by pressing two cutting rollers together and then using multiple cutters on the rollers. This type of slitting machine produces rough edges at the cutting point, easily generates debris and other waste, and the material is prone to deviation. Furthermore, the distance between the cutters is not easily adjustable, making it unsuitable for slitting different widths. Utility Model Content

[0035] like Figures 1-4As shown, one embodiment of this utility model is a film label laser slitting device, which includes a frame 1 and a slitting mechanism 2 disposed on the frame 1. The slitting mechanism 2 includes: a support base 21, a focus adjustment device 22, a movable plate 23, a first slide rail 24, a second slide rail 25, a drive plate 26, a drive device 27, multiple adjustment seats 28, and multiple laser cutting heads 29. The support base 21 is vertically disposed on the frame 1, the focus adjustment device 22 is disposed on the front side of the support base 21, the movable plate 23 is disposed on the working end of the focus adjustment device 22, and the first slide rail 24 is disposed on the front side of the support base 21. 4 is horizontally set on the movable plate 23, and the second slide rail 25 is vertically set on the movable plate 23; the drive plate 26 is slidably set on the second slide rail 25, and multiple guide grooves 261 are opened on its front side; the drive device 27 is set on the right side of the movable plate 23, and is used to drive the drive plate 26 to move vertically along the second slide rail 25; multiple adjustment seats 28 are slidably set on the first slide rail 24 respectively, and correspond one-to-one with the multiple guide grooves 261, and are slidably connected; multiple laser cutting heads 29 correspond one-to-one with the multiple adjustment seats 28 respectively, and are set on the front side of the adjustment seats 28.

[0036] In this embodiment, the film to be slit enters the working range of the slitting mechanism 2 from the rear end of the frame 1. The slitting mechanism 2 slits the film. The focal length adjustment device 22 of the slitting mechanism 2 is used to drive the movable plate 23 to move vertically, thereby adjusting the focal length between the multiple laser cutting heads 29 and the film to adapt to the cutting of films of different thicknesses, while improving the cutting accuracy and reducing the heat-affected zone, thereby reducing the generation of burrs. When the driving device 27 drives the driving plate 26 to move vertically along the second slide rail 25, the multiple adjusting seats 28 move horizontally along the first slide rail 24 under the constraint of the multiple guide grooves 261, thereby simultaneously adjusting the distance between the multiple adjusting seats 28, and then adjusting the distance between the multiple laser cutting heads 29 to adapt to the slitting requirements of different widths. The slit film is wound up at the front end of the frame 1.

[0037] In this embodiment, there are two first slide rails 24, which are horizontally arranged on the upper and lower sides of the movable plate 23 respectively, to ensure the movement stability of the multiple adjustment seats 28. There are also two second slide rails 25, which are arranged on the left and right sides of the movable plate 23 respectively, to ensure the movement stability of the drive plate 26.

[0038] In one embodiment, such as Figure 3 As shown, the focal length adjustment device 22 includes a first servo motor 221, a first lead screw 222 and a guide rail 23. The guide rail 23 is vertically arranged on the support base 21. The first servo motor 221 is arranged on the support base 21 at the top of the guide rail 23. The first lead screw 222 is arranged at the working end of the first servo motor 221. The movable plate 23 is slidably arranged on the guide rail 23 and is helically connected to the lead screw.

[0039] It is understood that the first servo motor 221 drives the first lead screw 222 to rotate. A nut is provided on the rear side of the movable plate 23. The nut and the lead screw are connected by a screw, which converts the rotation of the first lead screw 222 into vertical movement along the guide rail 23, thereby adjusting the lifting action of the movable plate 23 and adjusting the distance between the multiple laser cutting heads 29 and the film. In this embodiment, there are two guide rails 23, which are arranged parallel to each other to ensure the stability of the movement of the movable plate 23.

[0040] In one embodiment, such as Figure 4 As shown, the drive device 27 includes a second servo motor 271 and a second lead screw 272. The second servo motor 271 is vertically arranged on the right side of the movable plate 23, and the second lead screw 272 is arranged at the working end of the second servo motor 271 and is screwed to the drive plate 26.

[0041] It is understandable that a second nut is provided at the right end of the drive plate 26, and the second lead screw 272 is screwed to the second nut. The second servo motor 271 drives the second lead screw 272 to rotate, thereby driving the drive plate 26 to move vertically along the second slide rail 25.

[0042] In one embodiment, such as Figure 4 As shown, each adjustment seat 28 is provided with a slider 281 on its rear side, and multiple sliders 281 correspond one-to-one with multiple guide grooves 261 and are slidably connected.

[0043] In this embodiment, there are four guide grooves 261 and four adjustment seats 28. The four sliders 281 correspond one-to-one with the four guide grooves 261 and are slidably connected.

[0044] Furthermore, replacing the slider 281 with a roller, which is in rolling connection with the guide groove 261, can reduce the friction between the roller and the inner wall of the guide groove 261, prevent them from breaking each other, and extend their service life.

[0046] Understandably, the film is unwound by an external unwinding device and passes through multiple feed rollers 34 in sequence into the working range of the slitting mechanism 2. The servo cylinder 33 of the correction device 3 drives the adjusting frame 32 to move horizontally, thereby driving the multiple feed rollers 34 to move horizontally, and then driving the film on the feed rollers 34 to move horizontally, so as to adjust the position of the film and prevent the film from deviating.

[0047] In this embodiment, two guide posts are provided on the left side of the fixed frame 31, and two guide posts are also provided on the right side. Two guide sleeves are provided on the left side of the adjusting frame 32, and two guide sleeves are also provided on the right side. The two guide posts on the left side and the two guide sleeves on the left side correspond to each other and are slidably connected. The two guide posts on the right side and the two guide sleeves on the right side correspond to each other and are slidably connected. This ensures the stability of the horizontal movement of the adjusting frame 32.

[0048] In one embodiment, such as Figure 6 As shown, it also includes a detection device 4, which includes a fixed base 41, a mounting plate 42 and a correction sensor 43.
