Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to a negative pressure foam suction device. Background Art

[0002] The ZJ17 cigarette rolling and connecting machine is a cigarette rolling equipment with internationally advanced production technology level manufactured by domestic cigarette machinery factories after introducing technology from Germany's HAUNI company. It has the advantages of fast production speed, good cigarette quality, and automatic monitoring of the production process. It is currently the mainstream model in service in large and medium-sized domestic cigarette factories.

[0003] However, in the actual operation of the ZJ17 cigarette making machine, there is a long-term phenomenon of foam trapped at the joint between the mouthpiece and the cigarette, which not only seriously affects the appearance of the production, but also causes quality problems such as wrinkles on the tipping paper surface, failure of cigarette rubbing and change in suction resistance. In the entire MAX component, the position close to the tipping paper gluing device of the mouthpiece and where a large amount of foam is generated is the primary slitting wheel and the separation wheel. However, there is no foam collection device or removal device here to effectively collect the foam. The subsequent foam dust falls on the tipping paper of the gluing device, which is easy to cause quality problems such as wrinkles and curling of the cigarette. Utility Model Content

[0025] Example 1

[0026] like Figure 1-Figure 4 As shown, the utility model provides a negative pressure foam suction device, including a collector 1 connected to a negative pressure channel, and the specific structure of the collector 1 is: it includes an inclined panel, an arc-shaped collecting chamber 5 is provided on the back of the panel, and a collecting groove 7 is provided at the bottom end of the collecting chamber 5. The negative pressure channel is opened on the side of the collecting groove 7, one end of the negative pressure channel is connected to the collecting groove 7, and the other end of the negative pressure channel is connected to the negative pressure pump. A negative pressure pipe 3 connected to the negative pressure channel is installed on the side of the collecting groove 7 on the collector 1, and the negative pressure pipe 3 is connected to the negative pressure pump through a flange 4.

[0027] In order to facilitate the smoke foam to smoothly enter the collection groove 7 under the action of negative pressure, the technical solution designs the interior of the collection chamber 5 into a structural form in which the height gradually decreases from the surrounding area to the collection groove 7.

[0028] The collector 1 is provided with a collecting port connected to the collecting chamber 5 on one side close to the separation wheel. A protective net 6 is installed at the collecting port, and the protective net 6 can be fixed at the collecting port by screws. The mesh size of the protective net 6 can be set to 2mm*2mm to prevent the inhalation of large particles of tobacco leaves.

[0029] A blowing pipe 2 connected to the positive pressure channel is provided at the inlet end of the collecting chamber 5, and the positive pressure channel is connected to the air pump. A plurality of nozzles 8 are installed on the blowing pipe 2 at equal intervals along its axial direction, and the axial direction of the nozzle 8 is aligned with the separation wheel. In order to increase the blowing range of a single blowing pipe 2, the injection port of the nozzle 8 can be set to a fan-shaped structure.

[0030] After the smoke foam enters the collection chamber 5, some of the smoke foam will adhere to the inner wall of the collection chamber 5. In this technical solution, a vibration motor is fixedly installed on the outer side of the collector 1. By starting the vibration motor, the smoke foam attached to the inner wall of the collection chamber 5 is shaken off to achieve collection.

[0031] Example 2

[0032] Compared with Example 1, the present embodiment has the following technical features: slide rails are provided on both sides of the cavity mouth of the collecting cavity 5, and the slide rails are perpendicular to the axis of the blowing pipe 2. The two ends of the blowing pipe 2 are slidably mounted on the slide rails through sliders, so that the position of the blowing pipe 2 can be adjusted to achieve the most effective blowing effect and avoid the situation where the smoke foam cannot be effectively blown up at the blowing position. A threaded push rod can be provided on the side of the slider, and the threaded push rod passes through the slider from the side and then abuts against the slide rail. The threaded push rod and the slider are threadedly matched, and the position of the blowing pipe 2 can be fixed by tightening the threaded push rod.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
