Description

Technical Field

[0001] This utility model relates to the field of filter core paper processing technology, specifically to an online cutting device for cigarette filter core paper material. Background Technology

[0002] Cigarette filters are a major raw material in the tobacco industry, significantly impacting cigarette smoke filtration and flavor. Currently, the most common filter material for cigarette filters on the market is cellulose acetate tow. Compared to cellulose acetate tow filter rods, paper filter rods offer advantages such as better tar reduction and biodegradability, thus attracting widespread attention from filter rod manufacturers both domestically and internationally.

[0003] However, paper filter rods still suffer from problems such as a noticeable paper taste, dry smoke, high irritation, and unstable product quality. To address these issues, common modification methods currently focus on modifying the core paper material, including improving papermaking processes and exploring different plant fibers. Modified core paper materials exhibit significant differences in physical properties such as thickness, tensile strength, and toughness. During filter rod production, the width of the core paper material needs to be adjusted to suit the production capacity of the filter rod forming unit. Offline cutting of the core paper material is time-consuming and wasteful, hindering research into the production adaptability of new core paper materials. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0032] Please see Figures 1 to 7An online cutting device for cigarette filter core paper material according to an embodiment of the present invention includes a housing 1, a recycling component 4, a conveying component 2 for conveying core paper 5, and a cutting component 3 for cutting the core paper 5 conveyed by the conveying component 2. The conveying component 2 and the cutting component 3 are both disposed inside the housing 1 and respectively connected to the inner side of the housing 1; the recycling component 4 is disposed on the outer side of the housing 1, and one end of the recycling component 4 extends into the housing 1 to recycle the waste paper generated during cutting.

[0033] Here, during the operation of the device, the core paper 5 is transported to the cutting component 3 by the conveyor 2, and the cutting component 3 cuts the core paper 5 online. Waste paper is collected by the recycling component 4. The structure is simple, the operation is convenient, and it has strong adaptability, which improves the flexibility of paper filter rod research and production process and reduces material loss.

[0034] The outer casing 1 may include a back plate 11, a surrounding plate 12 connected to one side of the back plate 11, and a cutting cavity formed by the surrounding plate 12 and the back plate 11. The conveying component 2 includes an unwinding roller 21 and a roller assembly 22. The unwinding roller 21 and the roller assembly 22 are rotatably connected to the side of the back plate 11 near the cutting cavity. The unwinding roller 21 is used to fix the paper tube with the core paper 5 wound on it. A paper-passing hole is provided through the side of the surrounding plate 12 away from the unwinding roller 21. The roller assembly 22 is used to convey the core paper 5 drawn from the paper tube and can convey the core paper 5 through the paper-passing hole to the filter rod forming unit. The cutting component 3 is connected to the side of the back plate 11 near the cutting cavity and is used to cut the core paper 5 conveyed by the roller assembly 22. The recycling component 4 is fixedly connected to the side of the back plate 11 away from the cutting cavity.

[0035] Specifically, the cutting cavity can be a rectangular cavity. The outer shell 1 serves to fix the various components. The back plate 11 can be vertically arranged, and the surrounding plate 12 can include four sides, all of which are vertically connected to the back plate 11. Core paper 5 is wound on the paper tube, and the unwinding roller 21 is used to fix the paper tube. The unwinding roller 21 can rotate with the filter rod forming speed to complete the conveying of the core paper 5. The outer diameter of the unwinding roller 21 can match the inner diameter of the paper tube, so that the paper tube can be fitted onto the unwinding roller 21. An unwinding shaft is connected to the unwinding roller 21, and the unwinding shaft is rotatably connected to the back plate 11 through bearings. The paper tube can be interference-fitted with the unwinding roller 21.

[0036] Specifically, the conveyor 2 may also include a paper-jamming fastener disposed on the unwinding roller 21. When the paper tube is fitted onto the unwinding roller 21, the paper-jamming fastener can hold the paper tube in place, causing the core paper 5 to rotate, thus completing the output of the core paper 5 while preventing slippage. The outer casing 1 may also include a stop plate, which is disposed opposite to the back plate 11. The stop plate and the back plate 11 are respectively connected to the oppositely disposed two ends of the surrounding plate 12. The paper-jamming fastener refers to a protruding structure disposed on the unwinding roller 21. When it extends, one end protrudes from the outside of the unwinding roller 21, and when it retracts, it is inside the unwinding roller 21. The surface of the unwinding roller 21 is smooth. After pressing the button, one end of the protruding structure extends out and jams the inner wall of the paper tube, thus fixing the paper tube and preventing slippage.

[0037] Specifically, the conveying components also include multiple flanges, with both the unwinding roller 21 and the roller assembly 22 having flanges, which are connected to the back plate 11 by screws.

[0038] The back plate 11 may be provided with a first mounting through hole. The recycling component 4 includes a feed pipe 41, a first negative pressure generator 42, a discharge pipe 43, and a recycling box 44. The first negative pressure generator 42 is connected to the side of the back plate 11 away from the cutting cavity. One end of the feed pipe 41 is connected to one end of the first negative pressure generator 42, and the other end passes through the first mounting through hole and extends into the cutting cavity. The two ends of the discharge pipe 43 are respectively connected to the other end of the first negative pressure generator 42 and the recycling box 44.

[0039] Specifically, after the core paper 5 is cut by the cutter 3, the cut portion enters the embossing roller of the paper filter rod forming unit. The waste portion after cutting enters the feed pipe 41 of the recycling unit 4. The first negative pressure generator 42 generates negative pressure, sucking the waste paper into the feed pipe 41. The waste paper enters the discharge pipe 43 and finally enters the recycling bin 44, preventing the waste paper from drifting into the surrounding environment. The first negative pressure generator 42 is fixed to the back plate 11 with screws. The first negative pressure generator 42 can be the negative pressure generator disclosed in Chinese Patent CN213229327U, "A Label Foreign Object Adsorption Structure for Plastic Packaging Equipment".

[0040] The cutting component 3 may include a blade holder 32, a cutter 31 connected to the bottom of the blade holder 32, a support plate 37 connected to one side of the back plate 11 near the cutting cavity, and a connection structure connected to the blade holder 32 and the back plate 11 respectively. The support plate 37 is used to support the first part of the core paper 5 conveyed by the roller assembly 22, and the cutter 31 is used to cut the part of the core paper 5 located on the support plate 37.

[0041] Specifically, the core paper 5 passes through the carrier plate 37 and is cut into a set width by the cutter 31, thus realizing the function of fixed-width cutting of the core paper 5 material.

[0042] The connection structure may include a support frame 38, a servo motor 34, a linear guide rail 33, and an adjustment part connected to the linear guide rail 33 and the back plate 11 respectively. The top end of the cutter holder 32 is slidably connected to the sliding part of the linear guide rail 33. The servo motor 34 is used to drive the linear guide rail 33 so that the cutter holder 32 moves along the linear guide rail 33. The adjustment part is used to drive the support frame 38 to move towards or away from the support plate 37 so as to adjust the distance between the bottom end of the cutter 31 and the top end of the support plate 37.

[0043] Specifically, the linear guide rail 33 can be perpendicular to the back plate 11. The blade holder 32 is located on the linear guide rail 33, and the cutter 31 is fixed on the blade holder 32. The blade holder 32 can slide on the linear guide rail 33 through the servo motor 34, thereby completing the movement of the cutter 31.

[0044] The linear guide 33 may be equipped with a scale.

[0045] Specifically, the scale can display the distance that the tool holder 32 has moved.

[0046] The outer casing 1 may also include a second mounting through hole through the back plate 11, a first threaded groove on the back plate 11 located above the second mounting through hole, the bottom end of the first threaded groove communicating with the second mounting through hole, the adjustment part including an adjustment screw 35, a support frame 38 inserted into the second mounting through hole, the bottom end of the adjustment screw 35 being rotatably connected to the support frame 38, and the middle part of the adjustment screw 35 being screwed into the first threaded groove.

[0047] Specifically, the mounting portion of the linear guide 33 is connected to the bottom end of the support frame 38. One side end of the support frame 38 is inserted into the second mounting through hole. The adjusting screw 35 is connected to the support frame 38. By adjusting the screw 35, the linear guide 33 can be adjusted in the vertical position, thereby adjusting the feed depth of the cutter 31. The bottom end of the adjusting screw 35 passes through the first threaded groove and is rotatably connected to the portion of the support frame 38 inserted into the second mounting through hole. The middle part of the adjusting screw 35 is screwed into the first threaded groove. Changing the position of the adjusting screw 35 screwed into the first threaded groove allows adjustment of the position of the support frame 38. The support frame 38 may have a third mounting through hole. The adjusting part also includes a bearing located at the third mounting through hole. The bottom end of the adjusting screw 35 is not threaded. The bottom end of the adjusting screw 35 passes through the first threaded groove and is sleeved on the inner ring of the bearing.

[0048] The connection structure may also include a stop 36 disposed on the support plate 37 for limiting the cutting blade 31.

[0049] Specifically, the distance between the cutter 31 and the stop block 36 is 50-300mm, meaning that the cutting part 3 can achieve a cutting width of 50-300mm for the core paper 5.

[0050] The support plate 37 may have an adsorption chamber inside. The top of the support plate 37 is provided with a first adsorption through hole, and the side of the support plate 37 is provided with a second adsorption through hole. Both the first adsorption through hole and the second adsorption through hole are connected to the adsorption chamber. The cutting component 3 also includes a second negative pressure generator with one end connected to the second adsorption through hole.

[0051] Specifically, during the operation of the device, when the second negative pressure generator generates negative pressure, it can hold the core paper 5 on the support plate 37, preventing the core paper 5 from shifting left or right during the cutting process. The second negative pressure generator can be the negative pressure generator disclosed in Chinese Patent CN219666367U, "A Vacuum Adsorption Fixture for Processing Mobile Phone Back Panels".

[0052] The roller assembly 22 may include multiple unit rollers 221 that are rotatably connected to one side of the back plate 11 near the cutting cavity. The multiple unit rollers 221 are used to feed the core paper 5 in sequence. The cutter 31 is disposed between two adjacent unit rollers 221. The unwinding roller 21, the support plate 37, and the multiple unit rollers 221 are all perpendicular to the back plate 11, and the cutter 31 is parallel to the back plate 11.

[0053] Specifically, there can be four unit rollers 221, arranged sequentially along the direction of core paper 5 conveying. The cutting element 3 can be positioned between the second and third unit rollers 221. During the paper filter rod production process, the core paper 5 passes through the roller group and enters the cutting element 3. After cutting, it passes through the next two rollers and enters the paper filter rod forming unit. The support plate 37 and the linear guide rail 33 are both perpendicular to the back plate 11.

[0054] Specifically, the working process of the conveyor 2 is as follows: the paper tube with core paper 5 is placed on the unwinding roller 21, the paper clamping fastener is used to clamp the paper tube, the core paper 5 passes through the first unit roller 221 and the second unit roller 221 in sequence and enters the cutting part 3. After cutting, it passes through the third unit roller 221 and the fourth unit roller 221, and enters the paper filter rod forming unit through the through hole on the enclosure plate 12.

[0055] Specifically, the working process of the cutting part 3 is as follows: Adjust the servo motor 34 to control the position of the cutter 31. After the cutter 31 is adjusted to the design position by the scale on the linear guide rail 33, place the core paper 5 on the carrier plate 37. Control the cutting depth by adjusting the screw 35, and the core paper 5 completes the fixed width cutting.

[0056] Specifically, the working process of recycling component 4 is as follows: the first negative pressure generator 42 is turned on, and a negative pressure is generated at the feed pipe 41. After the waste paper is introduced into the feed pipe 41, it is sucked into the discharge pipe 43 under the action of gravity and negative pressure, floats out from the discharge pipe 43 and enters the recycling box 44.
