Description

Technical Field

[0001] The utility model relates to the technical field of laser film processing equipment, in particular to a laser film slitting machine with high-efficiency dust removal. Background Art

[0002] With the rapid development of the economy, the circulation of goods is very extensive. A large number of goods need to be packaged in packaging bags before entering the market. As manufacturers' awareness of preventing counterfeit and inferior products increases, manufacturers generally use laser anti-counterfeiting marks, which are printed with specific patterns and affixed to the outer packaging to remind consumers to distinguish between true and false. In the existing laser film production process, the laser film needs to be cut and divided into strips according to the required size. However, the traditional laser film slitting device will generate dust during the cutting process. This dust will be adsorbed on the surface of the laser laser film, causing the film surface to be blurred or scratched, seriously affecting the appearance and quality of the product, and has certain limitations.

The first dust suction duct 5 provided in the slitting and dust removal chamber 2 absorbs the dust generated by slitting the upper surface of the laser film, and the second dust suction duct 6 absorbs the dust generated by slitting the lower surface of the laser film, thereby improving the dust removal effect of the laser film slitting process, having strong continuous working ability, and being able to effectively improve product quality and production efficiency.

[0025] Preferably, a blowing module 7 for blowing away dust on the surface of the laser film is further provided in the slitting dust removal chamber 2, which can blow the dust on the surface of the laser film to the first dust suction duct 5, further improving the dust removal effect of laser film slitting.

[0026] Preferably, the first dust suction duct 5 includes a first housing 501, the input end of which is provided with a plurality of first air inlet holes 502, and the output end of which is provided with a first air outlet 503. The second dust suction duct 6 includes a second housing 601, the input end of which is provided with a plurality of second air inlet holes 602, and the output end of which is provided with a second air outlet 603. In this embodiment, the first air outlet 503 of the first dust suction duct 5 and the second air outlet 603 of the second dust suction duct 6 are both connected to a negative pressure generating device (such as an exhaust fan), thereby generating negative pressure at the first air inlet holes 502 and the second air inlet holes 602, thereby absorbing dust from the upper and lower surfaces of the laser film.

[0027] Preferably, a first flange 504 is provided on the outer periphery of the first housing 501, and the first dust suction duct 5 is fixedly connected to the divided dust removal chamber 2 via the first flange 504. A second flange 604 is provided on the outer periphery of the second housing 601, and the second dust suction duct 6 is fixedly connected to the divided dust removal chamber 2 via the second flange 604. In this embodiment, both the first housing 501 and the second housing 601 are flange-connected. The first housing 501 is fastened by bolts passing through the first flange 504 and the side wall of the divided dust removal chamber 2, thereby achieving the first housing 501 being mounted on the divided dust removal chamber 2. The second housing 601 is fastened by bolts passing through the second flange 604 and the side wall of the divided dust removal chamber 2, thereby achieving the second housing 601 being mounted on the divided dust removal chamber 2. This embodiment has the advantages of simple structure, high connection strength, and easy disassembly.

[0028] like Figure 5 As shown, preferably, the first shell 501 is a split structure, including a first inner-cavity shell 5011 and a first outer-cavity shell 5012, the first inner-cavity shell 5011 is fixedly connected to the inner wall of the divided dust removal chamber 2 through the first flange edge 504, and the first outer-cavity shell 5012 is fixedly connected to the outer wall of the divided dust removal chamber 2 through the first flange edge 504; the second shell 601 is a split structure, including a second inner-cavity shell 6011 and a second outer-cavity shell 6012, the second inner-cavity shell 6011 is fixedly connected to the inner wall of the divided dust removal chamber 2 through the second flange edge 604, and the second outer-cavity shell 6012 is fixedly connected to the outer wall of the divided dust removal chamber 2 through the second flange edge 604. In this embodiment, the first shell 501 and the second shell 601 are both designed as split structures. When it is necessary to clean and maintain the interior of the first dust suction duct 5 or the second dust suction duct 6, the first cavity outer shell 5012 or the second cavity outer shell 6012 can be disassembled to clean the interior of the shell. There is no need to disassemble the first dust suction duct 5 and the second dust suction duct 6 as a whole, which improves the inspection and maintenance efficiency.

[0029] Preferably, the first air inlet hole 502 extends to the upstream side of the slitting roller 4, the second air inlet hole 602 extends to the downstream side of the slitting roller 4, and the blowing module 7 is located on the downstream side of the slitting roller 4. In this embodiment, when the driving roller 3 drives the laser film to be transported, the cutter 401 on the slitting roller 4 cuts the laser film into strips, and some dust and debris are generated when the laser film is cut. By extending the second air inlet hole 602 of the second dust suction duct 6 to the downstream side of the slitting roller 4, the dust generated by the slitting of the lower surface of the laser film can be absorbed. By arranging the blowing module 7 on the downstream side of the slitting roller 4, the dust generated by the slitting of the upper surface of the laser film can be blown to the downstream side of the film, and then absorbed by the first air inlet hole 502 of the first dust suction duct 5, the dust removal effect of the laser film slitting machine is further improved.

[0030] Preferably, the frame 1 is provided with several groups of first guide rollers 8 located on the upstream side of the film inlet 201 and several groups of second guide rollers 9 located on the downstream side of the film outlet 202.
