Description

Anti-leak transmission device for cigarette machine spider

Technical field

The utility model belongs to leakage-preventing technical field, and in particular to a kind of anti-leak for cigarette machine spider transmits dress Put.

Background technology

Production main force type in cigarette industry is PT series cigarettee machines, including ZJ17 cigarette unit and ZJ112 high Fast cigarette unit.PT series cigarettee machines are to use spider transmission device, double long cigarette are delivered to mouthpieces attacter, spider passes Device is sent to occupy very important status in whole unit.But in production, often because spider transferring arm permeability and Cause cigarette surface to speckle with oil stain, cause equipment long-time shutdown maintenance, according to statistics, enterprises in 2015 are just as cigarette surface goes out Existing oil stain phenomenon causes equipment downtime more than 30 times, wherein being just up to four times more than 4 shutdown when small, replaces spider assembly one Set, 240,000 yuan of cost, maintenance cost is high, causes residual cigarette scrappage high.Transferring arm permeability is drawn by observation analysis in production Reason is as follows：The drive mechanism of spider assembly belongs to planetary gear structure, and inside is provided with substantial amounts of planetary gear, is running Cheng Zhong, these gears are rotated around main drive gear, drive eight cigarette transferring arms respectively, negative pressure is connected with inside transferring arm, Absorption transmission is carried out to the double long cigarette of roll-forming.In gear-box and transmission arm, there is a negative pressure circuit, ensure spider Hand suction socket has enough negative pressure to adsorb transmission cigarette, and it is negative to form one in the junction of spider transferring arm and gear-box Chamber is pressed, there are oil sealing sealing in negative pressure cavity both sides, but negative pressure cavity only has an oil sealing to separate with gear-box, are full of among negative pressure cavity Negative-pressure air-suction, negative-pressure air-suction can produce pressure to the oil sealing of both sides, cause oil sealing to deform, cause inside spider gear-box Fluid produces Seepage, into negative pressure channel, under high-speed rotating centrifugal force, is got rid of on cigarette surface, forms cigarette Branch is scrapped.It is therefore desirable to propose to improve.

Utility model content

The technical problem that the utility model solves：A kind of anti-leak transmission device for cigarette machine spider is provided, this Utility model can be such that negative pressure cavity is communicated with outside by setting pressure relief on transmission arm, balance its internal oil pressure, reduce and pass The pressure of negative pressure cavity and its both sides in arm is sent, prevents oil sealing from deforming, and combines the double action of multiple oil sealings, can effectively be prevented The oil stain leakage problem of transferring arm, avoids polluting cigarette, reduces cigarette scrappage, ensures production cost, reduces maintenance Number, extends service life of equipment, substantially reduces maintenance cost.

The technical solution adopted in the utility model：For the anti-leak transmission device of cigarette machine spider, including gear-box Housing, by bearings set with teeth inside the gear box casing, the tooth set is internal to be had by needle bearing rotational support Part tooth shaft, the gear box casing side are equipped with transmission arm, and described tooth shaft another part is placed in transmission arm, the transmission arm Main body in negative pressure channel and tooth shaft inner cavity junction formed a negative pressure cavity, the tooth shaft and main body of the negative pressure cavity corresponding position Junction, that is, negative pressure channel both sides are respectively equipped with multiple oil sealings, are equipped with and let out between negative pressure cavity at the body rim of the transmission arm Laminated structure.

Wherein, the main body junction and negative pressure channel both sides of the tooth shaft and transmission arm are respectively equipped with two oil sealings.

Further, the pressure relief includes the relief hole at the body rim of transmission arm, the master of the transmission arm Gap between body and tooth set and tooth shaft forms the pressure release passage that relief hole is connected with negative pressure cavity.

The utility model compared with prior art the advantages of：

1st, this programme can make negative pressure cavity by being equipped with pressure relief between negative pressure cavity at the body rim of transmission arm It is logical to be communicated with outside, negative pressure cavity internal oil pressure is balanced, so as to reduce the pressure of negative pressure cavity and its both sides in transferring arm, prevents oil sealing Deformation, can effectively prevent the oil stain leakage problem of transferring arm, avoid polluting cigarette, reduce cigarette scrappage, ensure Production cost；

2nd, by the tooth shaft of negative pressure cavity corresponding position and main body junction, that is, negative pressure channel both sides of transmission arm in this programme Multiple oil sealings are respectively equipped with, strengthen sealing effect, further prevent leakage problem；

3rd, effectively it can prevent transferring arm from leaking as a result of pressure relief and multiple oil seal structures in this programme Problem, prevents oil sealing from deforming, and prolongs the service life, and reduces maintenance frequency, the spider assembly component dismounting frequency is reduced by 90%, The service life of spider assembly can effectively be extended.
