In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the running direction of the belt 1 is the x direction shown in fig. 1, and the inner side of the belt 1 refers to the side where the upper belt surface 11 and the lower belt surface 12 contact the pulley 2. In the actual use process, the belt upper surface 11 is used for conveying tobacco shreds to be processed into a microwave bin for microwave heating, and as part of the tobacco shreds fall to the inner side of the belt lower surface 12 from the belt upper surface 11, along with the operation of the belt 1, the tobacco shreds move to the belt pulley 2 along with the belt 1 and contact with the belt pulley 2, so that the deviation of the belt 1 is caused to cause material breakage; or the slipping phenomenon between the belt pulley 2 and the belt 1 causes the heating time of the tobacco shreds in the microwave bin to be too long, so that the quality of the heated tobacco shreds is reduced, and even the tobacco shreds are ignited, thereby causing potential safety hazards such as fire and the like.

Referring to fig. 2, an embodiment of the present invention discloses a cleaning apparatus for cleaning dust inside a belt, including:

and the air blowing mechanism 4 is arranged at one side of the belt 1, the air blowing direction of the air blowing mechanism 4 is vertical to the running direction of the belt 1, and the air blowing mechanism 4 is used for blowing air into a space formed between the upper surface 11 and the lower surface 12 of the belt so as to blow dust on the lower surface 12 of the belt and separate the dust from the lower surface 12 of the belt.

The air suction mechanism 5 is arranged on the other side of the belt 1 and is opposite to the air blowing mechanism 4, the air suction mechanism 5 is used for sucking air and dust blown out by the air blowing mechanism 4, the air flow can be increased due to the air suction mechanism 5, and the blown dust is prevented from falling onto the lower surface 12 of the belt again to generate adverse effects on the operation of the belt 1.

By adopting the technical scheme, the air blowing mechanism 4 is arranged to blow air into the space formed between the upper surface 11 and the lower surface 12 of the belt, so that dust on the inner side of the belt 1 is blown to be separated from the lower surface 12 of the belt, and the air suction mechanism 5 is arranged to collect the blown dust, so that the dust is prevented from falling into the inner side of the belt 1 again to cause the phenomena of slippage and the like between the belt 1 and the belt pulley 2. The utility model overcomes the defects of the prior art, can effectively clean dust on the inner side of the belt 1, ensures the normal operation of the belt 1, further ensures the tobacco shred quality, and has simple structure and convenient use.

Alternatively, referring to fig. 2, the air blowing mechanism 4 includes:

a fixing bracket 41 provided at one side of the belt 1;

and the nozzle 42 is fixedly connected to the fixing bracket 41, wherein the fixed connection can be a welding mode, a threaded connection mode and the like. The cleaning device provided by the utility model blows the belt 1 in the running process of the belt 1, and the cleaning device can meet the requirement of dust cleaning when being in a static state relative to the belt 1. Therefore, it is necessary to fix the nozzle 42 to one side of the belt 1 via the fixing bracket 41 to blow the gas into the space formed by the upper belt surface 11 and the lower belt surface 12.

And one end of the air inlet pipe 43 is connected with the nozzle 42, and the other end is communicated with the high-pressure air source 8. Since most of the cut tobacco drops on the inner side of the lower belt surface 12, a very small amount of cut tobacco may adhere to the inner side of the upper belt surface 11 due to the roughness of the belt 1, and thus, when the dust is accumulated on the inner side of the lower belt surface 12, a high air pressure is required to blow the dust.

Alternatively, referring to fig. 2, the suction mechanism 5 includes:

the dust hood 51 is arranged at the other side of the belt 1, one end of the dust hood 51 is provided with a negative pressure air suction port 511, and the negative pressure air suction port 511 is arranged opposite to the nozzle 42, so that dust blown up by the air blowing mechanism 4 can be just adsorbed by the negative pressure air suction port 511, and the dust is prevented from falling into the inner side of the belt 1 again to influence the normal operation of the belt 1.

And one end of the dust removal pipe 52 is connected with the other end of the dust hood 51, and the other end of the dust removal pipe 52 is connected with the fan and used for collecting dust sucked by the negative pressure air suction port 511. The dust removal pipe 52 and the dust hood 51 are detachably connected, for example, by a clamp. When the tobacco shreds in the dust removal pipe 52 are more, the dust removal pipe 52 and the dust hood 51 can be separated, dust in the dust removal pipe 52 is cleaned independently, and the problem that the pipeline is blocked due to more dust in the dust removal pipe 52 is solved.

Alternatively, referring to fig. 3, the nozzle 42 is a cylinder and has a taper at its outlet end, the diameter of which is gradually reduced in the gas outflow direction. By adopting the technical scheme, the diameter of the air inlet end of the nozzle 42 can be larger than that of the air outlet end, so that the flow rate of air flow at the air outlet end is increased.

Optionally, referring to fig. 2, a valve 6 is further included, which is disposed on the air inlet pipe 43 and is used for adjusting the opening and closing of the air inlet pipe 43. In particular, the valve 6 may be a solenoid valve. When the belt 1 starts to run, the electromagnetic valve is electrified to enable the air inlet pipe 43 to be in an open state, so that high-pressure air reaches the nozzle 42 through the air inlet pipe 43, and dust on the inner side of the belt 1 is cleaned and blown. When the belt 1 stops running, the electromagnetic valve is de-energized, so that the air inlet pipe 43 is in a closed state.

Optionally, a pressure regulating valve 7 is further included, which is disposed on the air inlet pipe 43 and is used for regulating the air pressure in the air inlet pipe 43.

Alternatively, referring to fig. 2, the number of the nozzles 42 is plural, and the axes of the nozzles 42 are parallel to each other, so that the gas ejection directions from the nozzles 42 are kept uniform, and dust is prevented from being blown in all directions and being hardly sucked by the suction mechanism 5.

Alternatively, the pressure in the air inlet pipe 43 is 0.2-0.5Mpa, which is enough to blow the dust inside the belt 1, and prevent the dust 3 from flying in multiple directions due to the excessive pressure in the air inlet pipe 43 and being not sucked by the dust hood 51.

In operation, after the belt 1 runs, the valve 6 is opened, high-pressure gas reaches the nozzle 42 through the air inlet pipe 43 and is blown out from the nozzle 42, dust on the inner side of the belt 1 is blown to be separated from the lower surface 12 of the belt, and the air suction mechanism 5 acts simultaneously to collect the blown dust, so that the dust is prevented from falling into the inner side of the belt 1 again and affecting the running of the belt 1. When the belt 1 stops running, the valve 6 is closed, and the nozzle 42 and the suction mechanism 5 stop operating. According to the cleaning device provided by the utility model, the dust on the inner side of the belt is blown by the blowing mechanism 4 to be separated from the inner surface of the belt, and then the blown dust is collected by the suction mechanism 5, so that the dust is prevented from falling into the inner side of the belt 1 again to influence the normal operation of the belt 1. The cleaning device provided by the utility model can clean dust on the inner side of the belt 1, prevent the belt 1 from slipping, deviating and the like, ensure the normal operation of the belt 1, further ensure the quality of tobacco shreds, and has the advantages of simple structure and convenience in use.
