Description

Technical Field

[0001] This utility model relates to the field of disinfectant wipes processing technology, and in particular to a cutting device for a disinfectant wipes production line. Background Technology

[0002] The working principle of disinfectant wipes is mainly based on the killing or inhibition of microorganisms by their disinfectant ingredients. These ingredients disrupt the life activities of microorganisms through various mechanisms, leading to their death or loss of reproductive ability. Due to their portability and highly effective disinfection capabilities, disinfectant wipes are widely used in various daily life scenarios.

[0003] The processing flow of disinfectant wipes includes raw material preparation, non-woven fabric cutting, disinfectant solution preparation, spraying and impregnation, drying, folding and packaging, cutting and sealing, quality inspection, and finished product packaging. The non-woven fabric cutting step involves a cutting device, but the cutting process generates fiber debris, which, after being dispersed, can affect the surrounding processing environment. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for a disinfectant wipes production line, which has the function of collecting fiber debris under negative pressure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cutting device for a disinfectant wipes production line, comprising a frame, an unwinding mechanism disposed at one end of the frame for unwinding multiple rolls of non-woven fabric, and a cutting mechanism disposed on the frame. The cutting mechanism cuts multiple rolls of non-woven fabric as it moves along the width direction of the frame. A negative pressure hood is disposed on the frame above the cutting mechanism. An exhaust fan communicating with a dust cover is disposed on the top of the negative pressure hood. A filter for filtering fiber debris is disposed at the outlet of the exhaust fan. A partition is disposed inside the negative pressure hood to divide the inside of the negative pressure hood into multiple cavities corresponding to multiple rolls of non-woven fabric. Multiple negative pressure branch pipes communicating with the cavities are disposed on the top of the negative pressure hood. A negative pressure main pipe is disposed between the multiple negative pressure branch pipes and connected to the air inlet of the exhaust fan. Two ends of the bottom of the negative pressure hood are provided with unfoldable or retractable covering components. The covering components are used to gradually cover the cavities from both ends of the negative pressure hood during unfolding.

[0006] A further feature of this invention is that: two covering components are symmetrically arranged at both ends of the negative pressure hood, and connection ports are provided on both sides of the negative pressure hood; the covering components include a sliding rod slidably connected to the bottom of the negative pressure hood, an unwinding frame with a rotating shaft located on the outer side of the end of the negative pressure hood, a flexible rubber sheet with one end wound around the unwinding frame and the other end passing through the connection port and fixed to the sliding rod, a first locking member located on the unwinding frame and restricting or unlocking the rotation of the rotating shaft, and a second locking member located between the negative pressure hood and the sliding rod and restricting or unlocking the movement of the sliding rod.

[0007] A further feature of this invention is that a pull ring is provided at the bottom of the sliding rod, and a handle is provided at one end of the rotating shaft to drive the rotating shaft to rotate.

[0008] A further feature of this invention is that the first locking member includes a mounting sleeve disposed on the unwinding frame and through which the rotating shaft passes, and a first locking bolt threaded onto the mounting sleeve and used to abut against the circumference of the rotating shaft.

[0009] A further feature of this invention is that: multiple through holes are provided on both sides of the front side of the negative pressure cover, corresponding to the lower part of the partition plate; threaded holes are provided at both ends of the sliding rod; and the second locking member includes two second locking bolts that pass through the through holes and are threadedly connected to the threaded holes at the ends of the sliding rod.

[0010] In summary, the beneficial effects of this utility model are:

[0011] 1. When cutting nonwoven fabric, multiple unwinding mechanisms that combine rolls of nonwoven fabric are used to unwind the nonwoven fabric. The nonwoven fabric passes through the cutting mechanism, which moves along the width of the frame to cut multiple nonwoven fabrics. Fiber debris generated during the cutting process can be extracted by a negative pressure hood and a fan, and filtered through a filter. Considering that the cutting device cuts multiple nonwoven fabrics at the same time, if the number of nonwoven fabrics that do not need to be cut during production is small, the nonwoven fabric cutting at both ends of the frame width can be canceled first. At this time, by setting up partitions and covering components, the cavity at the bottom where the nonwoven fabrics that do not need to be cut can be covered, thereby ensuring the effect of negative pressure suction of fiber debris.

[0012] 2. When the covering component is in use, the flexible rubber sheet can be unwound by moving the sliding rod, and the flexible rubber sheet can be wound up by applying force to the wound flexible rubber sheet, thereby adjusting the number of cavities in the covering. After adjustment, it is fixed by the first locking member and the second locking member. At the same time, the pull ring and handle are provided to facilitate the unwinding and winding of the flexible rubber sheet. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: A cutting device for a disinfectant wipes production line includes a frame 1, an unwinding mechanism 2 disposed at one end of the frame 1 for unwinding multiple rolls of nonwoven fabric, and a cutting mechanism 3 disposed on the frame 1. The cutting mechanism 3 cuts multiple rolls of nonwoven fabric as it moves along the width direction of the frame 1.

[0020] like Figures 1 to 3 As shown, a negative pressure hood 4 is installed on the frame 1 above the cutting mechanism 3. A dust collector 5 is installed on the top of the negative pressure hood 4 and communicates with the dust cover. A filter 6 is installed at the outlet of the dust collector 5 to filter fiber debris. A partition 41 is installed inside the negative pressure hood 4 to divide the inside of the negative pressure hood 4 into multiple cavities 42 corresponding to multiple non-woven fabrics. Multiple negative pressure branch pipes 43 are installed on the top of the negative pressure hood 4 and communicate with the cavities 42 respectively. A negative pressure main pipe 7 is installed between the multiple negative pressure branch pipes 43 and connects to the air inlet of the dust collector 5. The two ends of the bottom of the negative pressure hood 4 are provided with unfoldable or retractable covering components 8. The covering components 8 are used to gradually cover the cavities 42 from both ends of the negative pressure hood 4 during the unfolding process.

[0021] like Figures 2 to 4 As shown, two cover components 8 are symmetrically arranged at both ends of the negative pressure cover 4. Connection ports (not marked in the figure) are provided on both sides of the negative pressure cover 4. The cover component 8 includes a sliding rod 81 slidably connected to the bottom of the negative pressure cover 4, an unwinding frame 82 provided on the outer side of the end of the negative pressure cover 4 and having a rotating shaft 821, a flexible rubber sheet 83 with one end wound on the unwinding frame 82 and the other end passing through the connection port and fixed on the sliding rod 81, a first locking member 84 provided on the unwinding frame 82 and restricting or unlocking the rotation of the rotating shaft 821, and a second locking member 85 provided between the negative pressure cover 4 and the sliding rod 81 and restricting or unlocking the movement of the sliding rod 81.

[0022] like Figures 2 to 4As shown, a pull ring 86 is provided at the bottom of the sliding rod 81, and a handle 87 is provided at one end of the rotating shaft 821 to drive the rotating shaft 821 to rotate.

Multiple through holes 44 corresponding to the lower part of the partition 41 are provided on both sides of the front side of the negative pressure cover 4. Threaded holes (not shown in the figure) are provided at both ends of the sliding rod 81. The second locking member 85 includes two second locking bolts that pass through the through holes 44 and are threadedly connected to the threaded holes at the ends of the sliding rod 81.

[0023] Implementation effect: When cutting nonwoven fabric, the unwinding mechanism 2, which combines multiple rolls of nonwoven fabric, unwinds the nonwoven fabric and passes through the cutting mechanism 3. The cutting mechanism 3 moves along the width direction of the frame 1 to cut multiple nonwoven fabrics. The fiber debris generated during the cutting process can be extracted by the negative pressure hood 4 and the exhaust fan 5, and filtered by the filter 6. At the same time, considering that the cutting device cuts multiple nonwoven fabrics at the same time, if the number of nonwoven fabrics that do not need to be cut during the production process is small, the nonwoven fabric cutting at both ends of the width direction of the frame 1 can be canceled first. At this time, the cavity 42 at the bottom where the nonwoven fabrics do not need to be cut is covered by the partition 41 and the covering component 8, thereby ensuring the effect of negative pressure suction of fiber debris.

[0024] When the cover assembly 8 is in use, the flexible rubber sheet 83 can be unwound by moving the sliding rod 81, and the flexible rubber sheet 83 can be wound up by applying force to the wound flexible rubber sheet 83, thereby adjusting the number of covered cavities 42, and after adjustment, it is fixed by the first locking member 84 and the second locking member 85; at the same time, the pull ring 86 and the handle 87 are provided to facilitate the unwinding and winding of the flexible rubber sheet 83.
