Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and in particular to a filter rod granule collection structure and a cigarette loading machine. Background Technology

[0002] In addition to developing different specifications such as slim and medium cigarettes, cigarettes have also developed new products such as adding flavor capsules to the filter tip and adding composite particles to the filter rod. Flavor capsules have a regular shape and high compatibility with the filter rod chamber, so there is no risk of them falling off during the entire production process; while composite particles are mostly irregular in shape, and the ends of the filter rod are not effectively sealed after cutting, so the composite particles are prone to being in a loose state inside the filter rod.

[0003] In existing cigarette filling machines, filter rods and tipping paper are conveyed separately via two roller-type production lines. The filter rod production line is located above the tipping paper production line, and both lines intersect with the cigarette pack production line at a certain point to ensure the tipping paper covers and bonds the filter rod and cigarette pack. However, during conveying, the composite particles inside the filter rod may fall off due to roller compression, equipment vibration, or loosening of the filter rod's own cut edges. These detached particles will fall directly onto the tipping paper, causing minor issues like protruding cigarette appearance or, in severe cases, air leakage, both of which affect the quality of the cigarette product.

[0004] Therefore, there is an urgent need for a structure that can prevent the composite particles of the filter rod from falling onto the tipping paper. Summary of the Invention

[0005] To overcome the technical defect of existing cigarette filling machines where filter rod composite particles easily fall onto the filling paper, this invention provides a filter rod particle collection structure and a cigarette filling machine.

[0006] The filter rod droplet collection structure provided by the present invention includes: An absorption plate, the plate surface is arranged horizontally and an absorption cavity is formed inside the plate, and a plurality of air suction holes are evenly distributed on the top surface of the absorption plate, the air suction holes are connected to the absorption cavity; A connecting rod, one end of which is fixedly connected to the side wall of the absorption plate, the connecting rod being a hollow rod to form a negative pressure channel in the hollow part, the negative pressure channel being connected to the absorption cavity; The base is fixedly connected to the other end of the connecting rod and is used to fix it on the cigarette filling machine. The base is provided with a negative pressure interface, which is connected to the negative pressure channel.

[0007] Optionally, the base is used to be detachably fixed to the cigarette receiving machine.

[0008] Optionally, the base is a strip plate, the connecting rod is connected to the middle part of the strip plate in the length direction, and the two ends of the strip plate in the length direction are provided with mounting holes. The strip plate is used to fix it to the cigarette packing machine by fasteners passing through the mounting holes.

[0009] The cigarette packing machine provided by this invention includes: A paper feeding line includes a gluing roller, a heater, and a paper cutting roller arranged in sequence, wherein the paper cutting roller is equipped with a rotary cutter. The filter rod production line is located above the paper receiving production line and includes a hopper, a cutting wheel, a staggered wheel and a combined wheel arranged in sequence. The aforementioned filter rod drop collection structure is fixed above the paper cutting wheel and the roller, and the negative pressure interface of the filter rod drop collection structure is connected to the valve island of the cigarette filling machine.

[0010] The technical solution provided by this invention has the following advantages compared with the prior art: The filter rod particle collection structure provided by this invention is fixed to a cigarette filling machine and connected to the valve island of the machine to generate negative pressure. The composite particles detached from the filter rod are drawn into the absorption chamber through the suction holes of the absorption plate. Then, under negative pressure, they are sequentially transported through the negative pressure channel and negative pressure interface to the valve island for centralized processing. This effectively prevents the composite particles detached from the filter rod from falling onto the tipping paper, thereby ensuring the quality of subsequent cigarettes.

[0011] The cigarette filling machine provided by the present invention has the aforementioned advantages because it has the aforementioned filter rod droplet collection structure. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0017] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0019] The following is combined with Figures 1 to 4 Specific embodiments of the present invention will be described in detail below. Example 1

[0020] This embodiment provides a filter rod droplet collection structure, including an absorption plate 1, a connecting rod 2, and a base 3.

[0021] The absorption plate 1 is horizontally arranged and has an absorption cavity 11 formed inside it. The top surface of the absorption plate 1 is evenly distributed with a plurality of air suction holes 12, which are connected to the absorption cavity 11.

[0022] Specifically, the dimensions of the absorption plate 1 are not limited. For example, in this embodiment, the dimensions of the absorption plate 1 are 240mm long × 140mm wide × 20mm high. The four corners of the absorption plate 1 are chamfered with R10. There are 12 × 7 suction holes 12. The distance between the outermost suction hole 12 and the edge of the absorption plate 1 is 10mm. The diameter of the suction hole 12 is 2mm and the depth is 2mm. The spacing between the suction holes 12 is 20mm.

[0023] It should be noted that the size of the suction hole 12 was determined by theoretical calculation using the wind pressure formula and combined with actual work and multiple experiments in this embodiment, ensuring that it can absorb particles without absorbing large debris that would cause the suction hole 12 to become clogged.

[0024] One end of the connecting rod 2 is fixedly connected to the side wall of the absorption plate 1. The connecting rod 2 is a hollow rod so that the hollow part forms a negative pressure channel 21, which is connected to the absorption cavity 11.

[0025] Specifically, the connecting rod 2 and the absorption plate 1 can be fixedly connected by means of integral molding, welding or fastener connection. However, it should be noted that, regardless of the method used, the negative pressure channel 21 and the absorption cavity 11 must be sealed and connected.

[0026] It is easy to understand that one side of the absorption cavity 11 needs to extend an opening to connect with the negative pressure channel 21.

[0027] The base 3 is fixedly connected to the other end of the connecting rod 2 and is used to fix it on the cigarette filling machine. The base 3 is provided with a negative pressure interface 31, which is connected to the negative pressure channel 21.

[0028] Specifically, the connecting rod 2 and the base 3 can be fixedly connected by means of integral molding, welding or fastener connection. However, it should be noted that, regardless of the method used, the negative pressure channel 21 and the negative pressure interface 31 must be sealed and connected.

[0029] Specifically, in this embodiment, the base 3 is used to detachably fix it to the cigarette filling machine. The detachable design of the base 3 allows the filter rod particle collection structure to be removed during the cleaning of the cigarette filling machine, preventing the filter rod particle collection structure from interfering with the cleaning of other components.

[0030] The detachable structure of the base 3 is not limited. For example, in this embodiment, the base 3 is a strip plate, and the connecting rod 2 is connected to the middle part of the strip plate along its length. The two ends of the strip plate along its length are provided with mounting holes 32. The strip plate is used to fix it to the cigarette filling machine by fasteners that pass through the mounting holes 32. The structure is simple and easy to assemble and disassemble.

[0031] The working principle of the filter rod particle collection structure in this embodiment is as follows: In use, the base 3 is fixed on the cigarette filling machine and located between the filter rod production line 200 and the filling paper production line 100. At the same time, the negative pressure interface 31 is connected to the valve island of the cigarette filling machine. When the composite particles of the filter rod fall off, the composite particles that originally fell on the filling paper are intercepted by the filter rod particle collection structure. The composite particles enter the absorption chamber 11 through the suction hole 12, and then are transported to the valve island for centralized processing in sequence through the negative pressure channel 21 and the negative pressure interface 31 under the action of negative pressure. Example 2

[0032] This embodiment provides a cigarette filling machine, including a filling paper production line 100, a filter rod production line 200, and the filter rod granule collection structure described in Embodiment 1.

[0033] The paper feeding line 100 and the filter rod feeding line 200 are existing structures. The paper feeding line 100 includes a gluing roller 110, a heater 120 and a paper cutting roller 130 arranged in sequence, and the paper cutting roller 130 is equipped with a roller cutter 140. The filter rod feeding line 200 is located above the paper feeding line 100 and includes a hopper 210, a cutting roller 220, a staggered roller 230 and a combined roller 240 arranged in sequence.

[0034] As is easily understood, the gluing roller 110 is used to apply glue to the tipping paper, the heater 120 is used to heat and soften the tipping paper to facilitate subsequent wrapping, the cutting roller 130 is used to work with the roller 140 to cut the tipping paper into a size that fits the cigarette and filter rod; the hopper 210 is used to store the filter rod, the cutting roller 220 is used to cut the filter rod into a specified length, the misalignment roller 230 is used to adjust the posture and spacing of the filter rod, and the unifying roller 240 is used to assemble the tipping paper, filter rod and cigarette.

[0035] It should be noted that the above only lists the main components of the cigarette packaging machine. In actual design, other functional components may be added, such as the acceleration wheel 250 located downstream of the combined wheel 240, which is used to feed the packaged cigarettes into the subsequent process; or the handwheel 300, which is used to manually turn the machine after it stops.

[0036] Among them, the filter rod drop collection structure is a new structure in this solution. The filter rod drop collection structure is fixed above the paper cutting wheel 130 and the roller 140. The negative pressure interface 31 of the filter rod drop collection structure is connected to the valve island of the cigarette receiving machine.

[0037] It is easy to understand that a valve island is an integrated pneumatic control component. Essentially, it integrates multiple solenoid valves, air circuit interfaces, and control interfaces into a modular unit for precise control of the on / off state, pressure regulation, or path switching of negative pressure airflow.

[0038] The working principle of the cigarette loading machine in this embodiment is as follows: During operation, the process of the tipping paper production line 100 is as follows: the tipping paper is first coated with glue by the gluing roller 110, then preheated by the heater 120, and then cut to the appropriate size by the cutting roller 130 and the roller 140. The process of the filter rod production line 200 is as follows: the filter rod is stored in the hopper 210. Under the action of the vibration of the hopper 210, the filter rod is output from the hopper 210 and first cut to the specified length by the cutting roller 220, then adjusted in posture and spacing by the offset roller 230, and finally reaches the unifying roller 240. At the unifying roller 240, the filter rod, tipping paper and cigarette are combined. The tipping paper wraps and bonds the filter rod and cigarette, and then the unwrapped cigarette is sent to the subsequent process by the accelerating roller 250. At the same time, when the filter rod is in the positions of the hopper 210, the cutting roller 220 and the offset roller 230, the fallen composite particles will fall onto the filter rod particle collection structure for collection.

[0039] When the machine is stopped, the negative pressure is shut off by controlling the solenoid valve. No negative pressure is generated in the filter rod droplet collection structure, so no energy is consumed and no noise is generated.

[0040] It should be noted that when the filter rod is at the positions of hopper 210, cutting wheel 220, and offset wheel 230, some of the detached composite particles will fall onto the tipping paper; however, when the filter rod is conveyed to the unifying wheel 240 and accelerating wheel 250, there is no risk of particles falling onto the tipping paper due to the greater distance from the already coated tipping paper. Considering the actual structural layout and particle drop positions, this solution installs the filter rod particle collection structure above the cutting wheel 130 and the roller 140, so that when the filter rod is at the positions of hopper 210, cutting wheel 220, and offset wheel 230, the filter rod particle collection structure can intercept and collect the falling composite particles.

[0041] The above are merely specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered within the protection scope of the claims.
