Description

Technical Field

[0001] This invention relates to the field of winding and splicing machine technology, specifically to a dust collection device for a filter tip splicing machine cover with an improved structure. Background Technology

[0002] In the production process of filter cigarettes, cigarettes are cut, separated, transferred and merged on the drum, and the tipping paper filter rods are attached. Occasionally, during the process of joining filter cigarettes, individual defective cigarettes that do not meet the quality requirements may occur, such as: wrinkled tipping paper, crooked overlap, yellow stains or water stains on the cigarette, tipping paper residue, and curled tipping paper edges, etc.

[0003] During the application and cutting of the tipping paper in the loading machine, the adhesive contains moisture. When heated by the post-adhesion heater, it produces water vapor. This moisture, upon contact with the cover plate and cooling, forms small water droplets. As these droplets accumulate, they form water droplets. These water droplets fall onto the glued tipping paper, creating rapidly expanding watermarks. While diluting the adhesive, this also causes deformation in that area, resulting in wrinkled tipping paper during the folding process. Water droplets falling onto the tobacco bundles on both sides create water stains and yellow spots on the cigarettes.

[0004] During the application and cutting of the tipping paper in the cigarette packing machine, some adhesive residue adheres to the tipping paper cutter. This residue is removed by a ball brush and falls into the lower part of the cover box. Excessive accumulation will cause it to fall onto the closing drum with the cigarette pack. When the tipping paper is pasted, this results in a defective cigarette with adhesive residue sandwiched in the tipping paper. Furthermore, during operation, the closing drum with the cigarette pack carries and lifts the tobacco dust generated when the drum handles the cigarettes. When this dust falls onto the glued tipping paper, the cigarette pack, during the twisting and wrapping process, simultaneously twists and wraps the tobacco dust with the tipping paper, creating a defective cigarette with tobacco residue sandwiched in the tipping paper. Summary of the Invention

[0005] The problem this invention aims to solve is to provide a dust extraction device for the cover plate of a filter tip assembly machine that simultaneously extracts cigarette smoke, moisture, and adhesive residue, addressing the aforementioned technical issues. Therefore, this invention proposes a dust extraction device for the cover plate of a filter tip assembly machine, which helps ensure the stable quality of filter cigarettes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A filter nozzle attachment cover dust collection device includes a cover box, which has an open front end and two open sides. A negative pressure interface is provided on the lower rear part of one side of the cover box. A glue powder negative pressure chamber is separated from the negative pressure interface by a first partition inside the cover box. The side of the glue powder negative pressure chamber away from the negative pressure interface is blocked. A gap is left at the bottom of the first partition to form a glue powder suction port. A smoke suction port and a water vapor suction port are respectively opened on the bottom and front of the cover box, and both the smoke suction port and the water vapor suction port are connected to the inside of the cover box.

[0008] Optionally, the bottom of the cover box is separated by a second partition to form a negative pressure chamber for tobacco, and the tobacco suction port is connected to the negative pressure chamber for tobacco.

[0009] Optionally, the front part of the cover box is separated by a third partition to form a water vapor negative pressure chamber, and the water vapor intake is connected to the water vapor negative pressure chamber.

[0010] Optionally, the tobacco negative pressure chamber and / or water vapor negative pressure chamber are connected to the adhesive negative pressure chamber and / or negative pressure interface.

[0011] Optionally, it also includes a duct cover plate, which is installed on one side of the cover box. The duct cover plate has a negative pressure duct, one end of which has a suction duct that connects to the water vapor negative pressure chamber, and the other end of which has a duct interface that connects to the tobacco negative pressure chamber / the glue negative pressure chamber.

[0012] Optionally, the duct cover has a frame structure, and its orientation is set along the opening edge of one side of the cover box.

[0013] Optionally, a cover is also included, which is mounted on the duct cover and blocks the opening of the cover box on that side.

[0014] Optionally, one end of the second partition passes through the gap at the bottom of the first partition, and the tobacco negative pressure chamber and the glue negative pressure chamber are connected.

[0015] Optionally, the height of the adhesive suction port ranges from 2 to 4 mm.

[0016] Optionally, there are two smoke inlets, each with a size of 36×6mm-45×5mm; and one water vapor inlet, with a size of 70×1mm-90×0.7mm.

[0017] Compared with the prior art, the present invention provides a dust collection device for a filter nozzle assembly cover, which has the following advantages:

[0018] 1. The present invention provides a water vapor suction port in the area where water vapor is generated on the cover plate box to draw out water vapor, so that condensation droplets cannot form at the front of the cover plate box; a smoke dust suction port is provided at the lower part of the cover plate box near the drum wheel to draw out the smoke dust and dust raised near the drum wheel before the smoke group and the coated cork paper sheet merge, thereby reducing the adhesion of smoke dust to the adhesive and achieving the effect of clean rubbing.

[0019] 2. Based on the original cover box, the present invention optimizes the negative pressure chamber and divides it into three negative pressure areas. Each negative pressure area performs a different suction function, while improving the suction capacity of different air inlets.

[0020] 3. This invention reduces the height of the suction port for the original adhesive powder, thereby improving the ability to extract the adhesive powder. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-3 As shown, this embodiment proposes a filter nozzle attachment cover dust collection device, including a cover box 1, an air duct cover 2, and a cover 3. The cover box 1 has an open front end and both sides. A negative pressure interface 4 is provided on the lower rear part of one side of the cover box 1, which is used to communicate with a negative pressure fan. The air duct cover 2 has a frame structure, and its orientation is set along the side edge of the opening on one side of the cover box 1, and the air duct cover 2 is installed on one side of the cover box 1. The cover 3 is installed on the air duct cover 2 and blocks the opening of the cover box 1 on that side.

[0027] In this embodiment, a glue-fee negative pressure chamber 501 is separated from the negative pressure interface 4 by a first partition 5 inside the cover box 1. The side of the glue-fee negative pressure chamber 501 away from the negative pressure interface 4 is sealed off. A gap is left at the bottom of the first partition 5. A tobacco-fee negative pressure chamber 601 is separated at the bottom of the cover box 1 by a second partition 6. Specifically, one end of the second partition 6 passes through the gap at the bottom of the first partition 5, so that the upper half of the gap forms a glue-fee suction port 502, and the lower half connects the tobacco-fee negative pressure chamber 601 and the glue-fee negative pressure chamber 501. The height of the glue-fee suction port 502 can be set to 2-4mm. Compared with the existing 7mm high glue-fee suction port 502, this embodiment improves the glue-fee suction port 502's ability to draw glue. The front part of the cover box 1 is separated by a third partition 7, forming a water vapor negative pressure chamber 701. The bottom and front parts of the cover box 1 are respectively provided with a smoke exhaust inlet 101 communicating with the smoke exhaust negative pressure chamber 601 and a water vapor exhaust inlet 102 communicating with the water vapor negative pressure chamber 701. The smoke exhaust inlet 101 is made of two rectangular inlets, each with dimensions of 36×6mm-45×5mm. The water vapor exhaust inlet 102 is a long inlet with dimensions of 70×1mm-90×0.7mm.

[0028] Furthermore, the tobacco negative pressure chamber 601 and / or water vapor negative pressure chamber 701 are connected to the adhesive negative pressure chamber 501 and / or negative pressure interface 4. In one specific embodiment, a negative pressure air duct 201 is provided on the aforementioned air duct cover plate 2. One end of the negative pressure air duct 201 passes through an air intake duct 203 that connects to the water vapor negative pressure chamber 701, and the other end of the negative pressure air duct 201 passes through an air duct interface 202 that connects to the tobacco negative pressure chamber 601 / adhesive negative pressure chamber 501. That is, all three negative pressure chambers are connected to the same negative pressure interface 4. Therefore, the principle of this embodiment is to use the negative pressure interface 4 to transfer negative pressure air to the glue powder negative pressure chamber 501 and the tobacco powder negative pressure chamber 601 in turn, and then transfer the negative pressure air to the water vapor negative pressure chamber 701 through the negative pressure air duct 201 on the air duct cover plate 2. Then, the glue powder, tobacco powder and water vapor are drawn out of the negative pressure interface 4 through the glue powder air inlet 502, the tobacco powder air inlet 101 and the water vapor air inlet 102 respectively, so that condensation water droplets cannot be formed at the front of the cover plate box 1, and at the same time, the tobacco powder adheres to the glue liquid to achieve clean rubbing, which is conducive to ensuring the quality stability of the filter cigarette.

[0029] This cover-mounted dust collection device is an optimization based on the original cover-mounted device. It optimizes a single negative pressure chamber into three negative pressure zones and makes corresponding openings to achieve different suction functions. At the same time, it adopts the original installation size and installation method, without the need for adjustment, and the on-site installation can be completed in one go.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
