Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a paper dust removal device for a slitting machine. Background Technology

[0002] Thermal paper has been widely used in people's daily lives, such as labels for daily necessities and food, cash register receipts, POS bank card readers, fax paper, and logistics labels.

[0003] Specialty processed paper coated outside the machine is prone to producing paper dust during slitting according to customer requirements due to the addition of inorganic fillers such as calcium carbonate and calcined kaolin in the coating. A small amount of paper dust does not affect the use, but as the slitting blade wears down, the amount of paper dust will increase, eventually affecting the normal use of the specialty paper. For example, if there is too much paper dust on specialty paper that needs to be printed, it will produce white spots in the printing. When printing on thermal paper, some paper dust will affect the printing, resulting in white spots in the color development. In severe cases, it will get stuck on the print head and produce continuous white lines. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a paper dust removal device for a slitting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example, refer to Figure 1-7 A paper dust removal device for a slitting machine includes a cutting roller 1, a first guide roller 2 and a second guide roller 3 located on the upper and lower sides of the cutting roller 1 for conveying special paper, a cutter 4 located on one side of the cutting roller 1, and a cutter holder 5 for mounting the cutter 4. In this embodiment, the cutting roller 1, the first guide roller 2, and the second guide roller 3 are connected to the frame of the slitting machine.

[0026] The cutter cleaning assembly 6, which is mounted on the cutter holder 5, is used to spray airflow onto the cutter 4 to clean the cutter 4;

[0027] The suction nozzle 7 is connected to the blade holder 5 via the linkage component 8 to achieve synchronous movement of the suction nozzle 7 and the cutter cleaning component 6. When the cutter 4 cuts the special paper substrate, the cutter cleaning component 6 sprays air according to the wear state of the blade to peel off the paper powder on the blade surface of the cutter 4, and captures the sprayed paper powder through the synchronously moving suction nozzle 7.

[0028] The dust-absorbing assembly 9 includes a baffle 901 located above the first guide roller 2, a through hole 906 penetrating the baffle 901, a suction pipe 903 connected to both sides of the baffle 901 via a flange 902, and a filter section 904. The suction pipe 903 is connected to the suction nozzle 7 via a hose 905. Preferably, in this embodiment, the horizontal height of the bottom end of the baffle 901 is lower than the horizontal height of the suction nozzle 7. Both ends of the baffle 901 are connected to the frame of the slitting machine. The filter section 904 is connected to a fan, which draws air into the dust-absorbing assembly 9, so that the paper dust near the suction nozzle 7 enters the suction pipe 903 and is filtered by the filter section 904.

[0029] This invention utilizes a high-pressure airflow jet from the cutter cleaning component 6 onto the blade surface of the cutter 4 to peel off paper dust adhering to the blade surface. The suction nozzle 7 moves synchronously with the cutter holder 5 via a linkage component 8, capturing the sprayed paper dust in real time. The airflow cleaning and suction nozzle 7 operate in sync, achieving efficient removal of paper dust. The dust suction component 9 uses a fan to draw air, causing the paper dust to enter the filter section 904 through the suction pipe 903 for filtration, effectively reducing the amount of paper dust falling onto the special paper after slitting and minimizing the impact of paper dust on subsequent applications.

[0030] In an optional embodiment of this utility model, the filter unit 904 includes a housing 9041, a filter screen 9042 disposed within the housing 9041, and an activated carbon layer 9043. Preferably, the filter screen 9042 in this embodiment can be a HEPA filter. The HEPA filter intercepts fine paper dust particles, and the activated carbon layer 9043 adsorbs odors and volatile substances. The dual filtration of the filter screen 9042 and the activated carbon layer 9043 improves the filtration effect on the air. At the same time, since the housing 9041 is connected to the baffle 901 through the flange 902, the filter screen 9042 and the activated carbon layer 9043 can be quickly replaced, supporting paper dust recycling and reducing waste disposal costs.

[0031] In an optional embodiment of this utility model, the cutter cleaning assembly 6 includes two sets of lugs 601 symmetrically distributed on both sides of the cutter 4, a swing plate 602 disposed on one side of the lugs 601, a rotating shaft 603 connected to both ends of the swing plate 602, a high-pressure jet nozzle 604 disposed on the rotating shaft 603 away from the lugs 601, and a limiting part 606 for limiting the rotating shaft 603 to adjust the jet direction of the high-pressure jet nozzle 604. Preferably, in this embodiment, one of the rotating shafts 603 is rotatably connected to the lugs 601 at both ends and to the swing plate 602. Plate 602 is fixedly connected, and the two ends of another rotating shaft 603 are rotatably connected to the swing plate 602 and fixedly connected to the high-pressure jet nozzle 604. The high-pressure jet nozzle 604 is connected to a high-pressure air pump. The swing plate 602 drives the high-pressure jet nozzle 604 to swing through the rotating shaft 603. The limiting part 606 adjusts the jet angle to ensure that the airflow accurately covers the blade surface. The symmetrically distributed high-pressure jet nozzles 604 enhance the cleaning uniformity and adapt to cutters with different wear conditions. The adjustable jet direction of the high-pressure jet nozzle 604 ensures that the blowing range covers the cutting area of ​​the cutter 4 and the cut edge of the substrate.

[0032] In an optional embodiment of this utility model, the limiting part 606 includes a sleeve 6061 disposed on the lug 601 and the swing plate 602, a guide post 6062 that slides with the sleeve 6061, a return spring 6063 connecting the bottom of the guide post 6062 and the sleeve 6061, an extension post 6064 disposed at one end of the guide post 6062, protrusions 6065 distributed in a ring array on the extension post 6064, and grooves 6066 disposed on the rotating shaft 603 corresponding to the protrusions 6065. Preferably, the guide post 6062 in this embodiment has a rectangular cross-section. The guide post 6062 locks the position of the rotating shaft 603 by cooperating with the protrusions 6065 and the grooves 6066. The return spring 6063 assists in the reset, driving the guide post 6062 to move into the sleeve 6061 so that the protrusions 6065 are inserted into the grooves 6066. The mechanical limiting structure is stable and reliable, preventing the high-pressure jet nozzle 604 from deviating.

[0033] In one optional embodiment of this utility model, a handle 6067 is provided at one end of the guide post 6062. The position of the guide post 6062 can be manually adjusted by the handle 6067 to control the limit state. The operation is convenient and can quickly adapt to different working conditions.

[0034] In an optional embodiment of this utility model, the linkage component 8 includes a slide rail 801, a slider 802 that slides with the slide rail 801, and a linkage plate 803 that connects the slider 802 and the suction nozzle 7. Preferably, in this embodiment, both ends of the slide rail 801 are connected to the frame of the slitting machine, and the blade holder 5 is fixedly connected to one side of the slider 802. When the blade holder 5 moves, it drives the slider 802 to slide along the slide rail 801, and the suction nozzle 7 follows synchronously through the linkage plate 803, ensuring that the suction nozzle 7 and the cutter 4 are strictly synchronized, thereby improving the paper dust removal efficiency.

[0035] In one optional embodiment of this utility model, the through hole 906 is honeycomb-shaped. The honeycomb-shaped through hole disperses the airflow and forms a uniform negative pressure area, which avoids excessive local airflow that could cause paper dust to escape and improves the dust absorption coverage.
