Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making machines, in particular to a bidirectional dust removal device for cigarette making and splicing equipment. Background Art

[0002] Cigarette rolling and splicing equipment such as the PROTOS70 utilizes the precise coordinated movement of a series of cylindrical drums to achieve processes such as cutting, splicing, and transporting cigarettes, as well as integrating cigarette paper and filter rods. However, at high operating speeds, this drum transmission method is prone to causing cigarette dust to splash. Due to the extremely compact and complex overall mechanical layout within the cigarette rolling and splicing equipment, cigarette dust is difficult to expel in a timely manner. Once the droplets enter the cigarette manufacturing process, significant impurity traces will form on the surface of the cigarette, seriously affecting the appearance quality. In order to effectively suppress various appearance defects caused by cigarette dust and improve the visual aesthetics of cigarette products, there is an urgent need for a dust removal device that can efficiently remove cigarette dust during the operation of the multiple drums.

[0003] The utility model patent with authorization announcement number CN220216177U discloses a dust removal device, including a main body arranged on one side of the drum along the radial direction of the drum, the surface of the main body including an air suction side, the air suction side and the circumferential surface of the drum being arranged opposite to each other and spaced a certain distance apart, a dust suction chamber is provided inside the main body, an air suction port is provided on the side wall of the dust suction chamber, the air suction port is connected to a negative pressure air source, a plurality of first dust suction holes connected to the dust suction chamber are provided on the air suction side, and the diameter of each first dust suction hole is proportional to the distance from the first dust suction hole to the air suction port.

[0004] However, such a device still has limitations. It can only absorb foam from a single drum through the suction side. For cigarette-making equipment with multiple drums operating continuously, multiple dust removal devices are required to independently remove dust from each drum, resulting in low space utilization and work efficiency. Furthermore, the limited dust removal range of a single suction side can lead to cross-contamination in the transition area between the two drums due to incomplete dust removal. This can cause droplets to enter the cigarettes, affecting the appearance and quality of the cigarette products. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a bidirectional dust removal device for cigarette rolling equipment, which can simultaneously deal with two sources of droplets, significantly improve space utilization and dust removal efficiency, reduce cross-contamination of cigarette dust between drum wheels, and avoid the risk of cigarette dust entering cigarette products.

[0006] The technical solution to the problem solved by the utility model is to provide a bidirectional dust removal device for a cigarette rolling and splicing device, the cigarette rolling and splicing device includes a plurality of drum wheels, and is characterized in that the bidirectional dust removal device includes a suction mechanism arranged between two adjacent drum wheels, the suction mechanism includes two suction surfaces for sucking out the smoke dust scattered by the drum wheels, and the two suction surfaces are respectively arranged towards the circumferential surfaces of the two drum wheels.

[0007] Furthermore, the bidirectional dust removal device for cigarette rolling equipment provided by the present invention may also have the following feature: the suction directions of the two suction surfaces are arranged at right angles.

[0008] Furthermore, the bidirectional dust removal device for cigarette rolling equipment provided by the present invention may also have the following feature: the air suction surface has a streamlined structure.

[0009] Furthermore, the bidirectional dust removal device for cigarette rolling equipment provided by the present invention may also have the following characteristics: the air suction mechanism includes a filter screen, and the filter screen covers the air suction surface.

[0013] Furthermore, the bidirectional dust removal device for cigarette rolling equipment provided by the present invention may also have the following characteristics: the mounting portion includes a bendable support member, one end of the support member is fixedly arranged, and the other end is connected to the suction mechanism.

[0014] Furthermore, the bidirectional dust removal device for cigarette rolling and splicing equipment provided by the present invention may also have the following feature: the support member includes a universal shaped hose.

[0015] Furthermore, the bidirectional dust removal device for cigarette rolling equipment provided by the present invention may also have the following feature: a handle is provided on the suction mechanism for manually applying force to bend the support member to adjust the position of the suction mechanism.

[0016] The beneficial effects of the utility model are:

[0018] 2. In this application, the two suction surfaces are further designed to be arranged at right angles so that each of them forms an independent suction area. Since the airflow directions of the two suction surfaces intersect vertically, mutual interference of the suction is effectively prevented, thereby ensuring the dust removal effect of this application on the two adjacent drum wheels.

[0019] 3. In this application, through flexible support members, the position of the suction mechanism can be adjusted in time according to the changes in the spatial layout of the cigarette rolling equipment to ensure that the suction surface is always at the optimal suction angle, thereby ensuring the dust removal effect.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Cigarette-joining equipment includes several drums, such as a transfer drum, a gathering drum, and a splicing drum. These drums work together to cut, join, and transport cigarettes, as well as integrate cigarette paper and filter rods. These drums operate at high speeds, which can cause cigarette dust to fly due to centrifugal force. This phenomenon can easily cause cosmetic defects in cigarettes.

[0027] In order to avoid the above-mentioned appearance defects, it is necessary to effectively remove the droplets on the drum surface. The utility model provides a two-way dust removal device for cigarette rolling and splicing equipment. The specific structure is as follows:

[0028] A two-way dust removal device for cigarette rolling equipment, such as Figure 1 and Figure 2 As shown, it includes a suction mechanism 1 arranged between two adjacent drum wheels, and the suction mechanism 1 includes two suction surfaces 2 for sucking out the smoke dust scattered from the drum wheels, and the two suction surfaces 2 are respectively arranged facing the circumferential surfaces of the two drum wheels. Since the overall mechanical layout inside the cigarette rolling and joining equipment is extremely compact and complex, the utility model can efficiently utilize the limited installation space, treat two sources of droplets at the same time, and reduce the cross-contamination of droplets between the drum wheels. Compared with traditional one-way dust removal devices, the utility model has higher space utilization and dust removal efficiency, can provide better dust removal effect, and reduce the risk of smoke dust entering the finished cigarettes.

[0029] In some embodiments, the suction directions of the two suction surfaces 2 are arranged at right angles. When in use, the airflow directions of the two suction surfaces 2 intersect perpendicularly, effectively preventing the suction from interfering with each other, ensuring that the two suction surfaces 2 each independently form a suction area, and ensuring the dust removal effect of the present application on two adjacent drums.

[0030] In some embodiments, the suction surface 2 has a streamlined structure, which can adapt to the circumferential surface shape of the drum wheel to reduce the escape of droplets. Moreover, the smooth curved contour of the streamlined structure can effectively reduce the resistance to air flow during the suction process, further enhancing the dust removal effect.

[0031] In some embodiments, the suction mechanism 1 includes a filter 3, which covers the suction surface 2 and is used to block cigarettes that are not close to the drum wheel and prevent them from entering the interior of the two-way dust removal device with the negative pressure wind of the suction mechanism 1.

[0032] In some embodiments, the bidirectional dust removal device further includes an air supply unit and an air suction duct 4. The air supply unit can provide continuous and stable suction power for the entire dust removal system. One end of the air suction duct 4 is connected to the air supply unit, and the other end is connected to the air suction mechanism 1, which can safely and effectively transport the smoke-containing air captured by the air suction mechanism 1 from the vicinity of the drum wheel to the next processing link of the dust removal system. As a further improvement of this embodiment, the air supply unit includes a vacuum generator for generating negative pressure. Compared with traditional negative pressure dust removal devices that rely on structures such as fans to generate negative pressure, the vacuum generator is smaller in size and has higher space utilization. It can also utilize the compressed air resources of the compressed air supply system that is usually available in the cigarette rolling equipment, without the need for additional power equipment such as electric motors, and is more energy-efficient.

[0033] In some embodiments, the bidirectional dust removal device also includes a mounting portion for mounting the suction mechanism 1, which can provide stable support for the suction mechanism 1. As a further improvement of this embodiment, the mounting portion includes a bendable support member 5, one end of the support member 5 is fixed, and the other end is connected to the suction mechanism 1. The flexible support member 5 gives the suction mechanism 1 high flexibility, and can be adaptively adjusted according to the complex and potentially variable spatial layout inside the cigarette rolling equipment. When in use, the suction mechanism 1 can be adjusted to an ideal working position by bending the support member 5, ensuring that the suction surface 2 is always at the optimal suction angle, thereby ensuring the dust removal effect. In order to ensure that the support member 5 can be bent while maintaining its shape, no additional fixing device is required to fix the suction mechanism 1. Preferably, the support member 5 is a universal shaped hose, and this embodiment can be implemented in combination with the aforementioned embodiment, such as Figure 2 As shown, the suction duct 4 is arranged inside the universal shaped hose, which realizes the high integration of the dust removal system, avoids occupying external space, and further improves space utilization.

[0034] In some embodiments, the suction mechanism 1 is provided with a handle 6 for manually applying force to bend the support member 5 and thereby adjust the position of the suction mechanism, providing a convenient force point for the operator performing adjustment and maintenance. By simply holding the handle 6 and applying appropriate force, the bending state of the support member 5 can be easily changed, thereby adjusting the relative position between the suction structure and the drum wheel.

[0035] The contents described above can be implemented individually or in combination in various ways, and these variations are all within the scope of protection of the present invention.
