Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a cleaning device for a tipping paper cutter and a tipping paper cutting device. Background Technology

[0002] As a packaging material for cigarette filters, the cutting precision of tipping paper directly affects the quality of the finished cigarette. Currently, tipping paper is cut using tipping paper cutting equipment. The cutting blade of this equipment is mounted on a cutting wheel; the rotation of the cutting wheel drives the cutting blade to cut the tipping paper.

[0003] After cutting, adhesive and other contaminants remain on the cutter blades of tipping paper cutting equipment, causing glue residue and affecting cutting performance, resulting in defective tipping paper. This necessitates downtime maintenance of the equipment, directly impacting its operating efficiency. Existing tipping paper cutting equipment typically includes a cleaning device to clean the cutter blades after cutting. This device typically uses a brush fixed to a drive shaft, which is driven by a mechanism to rotate, thus rotating the brush. The brush and cutter blade rotate in an engaging manner to clean the blade.

[0004] Because both the brush and the paper cutter rotate independently, and the linear velocity of the brush tip matches that of the paper cutter, there is no relative sliding between them. This means there is no relative wiping action, resulting in a smaller cleaning area and poorer cleaning effect. Furthermore, excessive bending of the brush can also reduce its lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning device for a tipping paper cutter and a tipping paper cutting device. The bristles move back and forth along the axial direction of the reciprocating screw, so that there is a relative wiping action between the bristles and the paper cutter along the axial direction of the reciprocating screw, which increases the cleaning area of ​​the bristles on the paper cutter. Furthermore, the rotation of the paper cutter drives the bristles to rotate, which allows the bristles to slide relative to the paper cutter, thereby wiping the paper cutter and further increasing the cleaning area of ​​the bristles on the paper cutter, thus improving the service life of the bristles.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On one hand, a tipping paper cutter cleaning device is provided, the tipping paper cutter cleaning device being mounted on a frame, the tipping paper cutter cleaning device comprising:

[0008] Reciprocating lead screw;

[0009] A drive mechanism is connected to the reciprocating lead screw, and the drive mechanism is capable of driving the reciprocating lead screw to rotate;

[0010] A first bearing, the inner ring of which is connected to the reciprocating screw, the reciprocating screw driving the first bearing to reciprocate along the axial direction of the reciprocating screw;

[0011] A brush tube is sleeved on the first bearing and fixedly connected to the outer ring of the first bearing, and brush bristles are provided on the outer wall of the brush tube.

[0012] Optionally, the cork paper cutter cleaning device further includes a slider with a threaded hole, the reciprocating screw being threaded into the threaded hole, and the inner ring of the first bearing being fixedly connected to the slider.

[0013] Optionally, the first bearing is sleeved on the outer wall of the slider and is interference-fitted with the outer wall of the slider.

[0014] Optionally, the tipping paper cutter cleaning device further includes a second bearing, the inner ring of which is fixedly connected to the reciprocating lead screw, and the outer ring of which is fixedly connected to the frame.

[0015] Optionally, the cork paper cutter cleaning device further includes a guide rod, one end of which is connected to the outer ring of the second bearing, and the other end of which extends axially along the reciprocating lead screw. The slider is slidably connected to the guide rod along the axial direction of the reciprocating lead screw.

[0016] Optionally, the slider is provided with a through hole extending axially along the reciprocating lead screw, the guide rod passes through the through hole, and the outer wall of the guide rod is in contact with the inner wall of the through hole.

[0017] Optionally, at least two guide rods are provided, and at least two guide rods are arranged in parallel.

[0018] Optionally, the cork paper cutter cleaning device further includes a first gear, which is fixedly connected to the reciprocating lead screw. The drive mechanism includes a motor and a second gear, with the motor drivingly connected to the second gear and the second gear meshing with the first gear.

[0019] Optionally, the bristles are evenly distributed on the outer wall of the brush cylinder.

[0020] On the other hand, a tipping paper cutting device is provided, including a frame, a cutting wheel, a plurality of cutting blades, and the aforementioned tipping paper cutting blade cleaning device. The cutting wheel is rotatably connected to the frame, and the plurality of cutting blades are arranged circumferentially around the cutting wheel and connected to the outer wall of the cutting wheel. The axis of the cutting wheel is parallel to the axis of the reciprocating screw, and the reciprocating screw is rotatably connected to the frame. The bristles are capable of abutting against the cutting blades.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a cleaning device for tipping paper cutters and a tipping paper cutting device. The tipping paper cutting device includes a frame, a cutting wheel, multiple cutting blades, and a tipping paper cutter cleaning device. The tipping paper cutter cleaning device includes a reciprocating screw, a drive mechanism, a first bearing, and a brush cylinder. Bristles are provided on the outer wall of the brush cylinder. The reciprocating screw drives the first bearing to reciprocate along the axial direction of the reciprocating screw, causing the brush cylinder to reciprocate along the axial direction of the reciprocating screw, thereby causing the bristles to reciprocate along the axial direction of the reciprocating screw. The bristles and the cutting blades slide relative to each other along the axial direction of the reciprocating screw, i.e., there is a relative wiping action between the bristles and the cutting blades along the axial direction of the reciprocating screw, increasing the cleaning area of ​​the bristles on the cutting blades and improving the cleaning effect. Furthermore, during operation, the tipping paper cutting device drives the cutting blades to rotate by the rotation of the cutting wheel around its central axis. The bristles extend to the side of the paper cutter. The rotation of the paper cutter engages with the bristles, and its continued rotation further drives the bristles. Since the brush cylinder is rotatably connected to the reciprocating screw via a first bearing, the screw's rotation does not cause the brush cylinder to rotate. The bristles only rotate under the push of the paper cutter. A relative sliding action occurs between the bristles and the paper cutter along the radial direction of the reciprocating screw, further increasing the cleaning area and improving the cleaning effect. Furthermore, the brush cylinder's ability to rotate the bristles prevents excessive bending, extending their lifespan. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] like Figures 1-3As shown, this embodiment provides a tipping paper cutting device, including a frame 100, a cutting wheel 200, multiple cutting blades 300, and a tipping paper cutting blade cleaning device. The cutting wheel 200 is rotatably connected to the frame 100, and the multiple cutting blades 300 are arranged circumferentially around the cutting wheel 200 and connected to the outer wall of the cutting wheel 200. The tipping paper cutting blade cleaning device is installed on the frame 100 and includes a reciprocating screw 1, a drive mechanism, a first bearing 2, and a brush cylinder 3. The drive mechanism is driven and connected to the reciprocating screw 1, and the drive mechanism can drive the reciprocating screw 1 to rotate. The inner ring of the first bearing 2 is connected to the reciprocating screw 1, and the reciprocating screw 1 drives the first bearing 2 to reciprocate along the axial direction of the reciprocating screw 1. The brush cylinder 3 is sleeved on the first bearing 2 and fixedly connected to the outer ring of the first bearing 2, and brush bristles 4 are provided on the outer wall of the brush cylinder 3. The axis of the paper cutting roller 200 is parallel to the axis of the reciprocating lead screw 1, the reciprocating lead screw 1 is rotatably connected to the frame 100, and the bristles 4 can abut against the paper cutter 300.

[0034] The reciprocating screw 1 drives the first bearing 2 to reciprocate along the axial direction of the reciprocating screw 1, causing the brush cylinder 3 to reciprocate along the axial direction of the reciprocating screw 1. This, in turn, causes the bristles 4 to reciprocate along the axial direction of the reciprocating screw 1. The bristles 4 and the paper cutter 300 slide relative to each other along the axial direction of the reciprocating screw 1, meaning there is a relative wiping action between the bristles 4 and the paper cutter 300, increasing the cleaning area of ​​the bristles 4 on the paper cutter 300 and improving the cleaning effect. Furthermore, during operation, the paper cutting equipment rotates the paper cutting wheel 200 around its central axis, thereby driving the paper cutter 300 to rotate. The bristles 4 extend to the side of the paper cutter 300, and the rotation of the paper cutter 300 allows it to contact the bristles 4. Continued rotation of the paper cutter 300 further pushes the bristles 4 to rotate. Since the brush cylinder 3 is rotatably connected to the reciprocating screw 1 via the first bearing 2, the rotation of the reciprocating screw 1 does not drive the brush cylinder 3 to rotate. The bristles 4 only rotate under the push of the paper cutter 300. The bristles 4 and the paper cutter 300 will slide relative to each other in the radial direction of the reciprocating screw 1. That is, there is a relative wiping action between the bristles 4 and the paper cutter 300 in the radial direction of the reciprocating screw 1, which further increases the cleaning area of ​​the bristles 4 on the paper cutter 300 and improves the cleaning effect of the bristles 4 on the paper cutter 300. In addition, the brush cylinder 3 can drive the bristles 4 to rotate, and the bristles 4 will not have excessive bending, thus improving the service life of the bristles 4.

[0035] Specifically, the frame 100 is plate-shaped. A first mounting hole is provided on the frame 100, through which the paper-cutting wheel 200 passes and can rotate relative to the inner wall of the first mounting hole. The paper-cutting blade 300 is a rectangular sheet structure. The paper-cutting blade 300 is fixedly connected to the side wall near one end of the paper-cutting wheel 200. A second gear 400 is provided at the end of the paper-cutting wheel 200 away from the paper-cutting blade 300. A motor drives the second gear 400 to rotate, thereby causing the paper-cutting wheel 200 to rotate.

[0036] Optionally, the paper tipper cleaning device also includes a slider 5, which has a threaded hole. A reciprocating screw 1 is threaded into the threaded hole, and the inner ring of the first bearing 2 is fixedly connected to the slider 5. Rotation of the reciprocating screw 1 can drive the slider 5 to reciprocate along the axial direction of the reciprocating screw 1, thereby driving the first bearing 2 to reciprocate along the axial direction of the reciprocating screw 1. Specifically, the slider 5 has a cylindrical structure, and the threaded hole extends along the axial direction of the slider 5 and is located at the center of the slider 5. In other embodiments, the inner ring of the first bearing 2 can also be directly provided with a thread that mates with the reciprocating screw 1 and is threadedly connected to the reciprocating screw 1.

[0037] Furthermore, the first bearing 2 is sleeved on the outer wall of the slider 5 and is interference-fitted with the outer wall of the slider 5, which facilitates the installation of the first bearing 2.

[0038] Optionally, the tipping paper cutter cleaning device further includes a second bearing 6. The inner ring of the second bearing 6 is fixedly connected to the reciprocating lead screw 1, and the outer ring of the second bearing 6 is fixedly connected to the frame 100. By setting the second bearing 6, the reciprocating lead screw 1 can be fixed on the frame 100, and the reciprocating lead screw 1 can rotate relative to the frame 100. Specifically, the inner ring of the second bearing 6 is interference-fitted onto the outer wall of the reciprocating lead screw 1, and the frame 100 is provided with a second mounting hole. The outer ring of the second bearing 6 is interference-fitted with the inner wall of the second mounting hole. In other embodiments, the tipping paper cutter cleaning device further includes a bearing seat, which is fixed in the second mounting hole. The bearing seat is provided with a third mounting hole, and the outer ring of the second bearing 6 is interference-fitted with the inner wall of the third mounting hole.

[0039] Optionally, the paper tipper cleaning device further includes a guide rod 7. One end of the guide rod 7 is connected to the outer ring of the second bearing 6, and the other end of the guide rod 7 extends axially along the reciprocating lead screw 1. The slider 5 is slidably connected to the guide rod 7 along the axial direction of the reciprocating lead screw 1. The guide rod 7 can restrict the radial rotation of the slider 5 along the reciprocating lead screw 1 and guide the slider 5 to ensure that the slider 5 moves back and forth along the axial direction of the reciprocating lead screw 1 when the reciprocating lead screw 1 rotates. Specifically, one end of the guide rod 7 can be fixed to the outer ring of the second bearing 6 by welding, bonding, snap-fitting, etc., which is not limited in this embodiment.

[0040] Furthermore, the slider 5 is provided with a through hole extending along the axial direction of the reciprocating lead screw 1, and the guide rod 7 passes through the through hole. The outer wall of the guide rod 7 fits against the inner wall of the through hole, thereby improving the stability of the slider 5 movement.

[0041] Optionally, at least two guide rods 7 are provided, and the two guide rods 7 are arranged in parallel to improve the stability of the slider 5 movement. Specifically, the two guide rods 7 are respectively arranged on both sides of the central axis of the reciprocating lead screw 1.

[0042] Optionally, the tipping paper cutter cleaning device further includes a first gear 8, which is fixedly connected to the reciprocating lead screw 1. The drive mechanism includes a motor and a second gear 400. The motor is driven by the second gear 400, which meshes with the first gear 8. The motor drives the second gear 400 to rotate, which in turn drives the first gear 8 to rotate, thereby realizing the rotation of the reciprocating lead screw 1. Specifically, the first gear 8 is interference-fitted onto the side of the reciprocating lead screw 1 away from the slider 5.

[0043] Optionally, the bristles 4 are evenly distributed on the outer wall of the brush barrel 3, so that the bristles 4 make more even contact with the paper cutter and improve the cleaning effect.
