Description

Tobacco stem inner hemp removal and separation device

technical field

The invention belongs to the technical field of cigarette production, and in particular relates to a device for removing and separating flax in tobacco stems.

Background technique

At present, the pretreatment of tobacco stems in the silk workshop of cigarette factories generally adopts the operation method of manually throwing stems and unpacking them. On the other hand, when the sack is opened manually, a cutter is used to cut the sack, and the tobacco stems are poured into the feeding belt conveyor, and a certain amount of hemp silk is produced during the cutting of the sack. When these entangled debris such as hemp silk and nylon rope are thrown into the air distribution box at the same time as the tobacco stems, the light hemp silk, nylon rope and other debris enter the dust collector along with the dust removal pipe, and then enter the rod pressing machine through the auger. Press rods to form smoke, dust and sundries. A large amount of easily entangled sundries such as hemp silk and nylon rope are entangled on the main shaft of the auger when passing through the auger, causing the auger to run overloaded, resulting in failures such as overload and main shaft breakage.

Contents of the invention

In order to solve the deficiencies in the prior art, the present invention provides a device for removing and separating flax in tobacco stems with simple structure, high degree of automation and low labor intensity.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: the hemp shred removal and separation device in the tobacco stem includes a bracket, a winnowing box is arranged on the bracket, a feed inlet is arranged on the top of the front side of the winnowing box, and the front side of the winnowing box is There is an air inlet, there is a throwing roller in the winnowing box, there is an air outlet pipe on the top of the winnowing box, and a butterfly valve is set on the outlet pipe to control the air flow. Wire cleaning mechanism.

The hemp silk cleaning mechanism comprises a motor reducer, a driving roller, a driven roller, an air knife, a brush roller, a scraper, a feeding hopper and an endless mesh belt, and the power output end of the motor reducer is connected to one end of the driving roller through transmission. The driving roller and the driven roller are connected by mesh belt transmission, and the mesh belt is set horizontally and is located at the connection between the winnowing box and the air outlet pipe. The scrapers are all set directly above the feeding hopper, the air knife is set between the upper half and the lower half of the mesh belt, the air outlet of the air knife faces the lower half of the mesh belt, and the brush roller and scraper are set on the lower half of the mesh belt Below, the upper side of the brush roller and the scraper is in contact with the lower surface of the lower half of the mesh belt, and the brush roller is located at the outer side of the scraper and connected with the driving roller.

Using the above technical scheme,

The material is sent into the feed inlet through conveying equipment such as a belt conveyor, and the material is thrown by the throwing roller and scattered in the winnowing box. The high-pressure airflow enters through the air inlet and passes through the dispersed material. The heavier tobacco stems settle and fall to the conveying equipment below, while the lighter flax, dust and other light impurities rise with the airflow and are adsorbed on the mesh belt, and the motor reducer drives the driving roller , the driving roller drives the driven roller to rotate through the mesh belt. During the operation of the mesh belt, the hemp silk, dust and other debris attached to the mesh belt will be taken out of the winnowing box, and then part of the hemp will be scraped off by the hanging sweep of the scraper. At the end of the mesh belt, the blowing of the air knife and the scraping of the brush roller further clean the residual hemp on the mesh belt. The hemp cleaning is more thorough, so that the hemp and other sundries fall into the discharge hopper collect.

The butterfly valve on the air outlet pipe is used to adjust the wind speed of the winnowing box. The invention installs a safety shield on the moving parts to ensure that the operator is prevented from being injured during the operation of the machine; the motor is equipped with overload and phase loss protection devices to ensure the reliable and safe operation of the machine. And ensure that dust will not pollute the workshop.

The control system of the present invention adopts PLC and frequency conversion control technology, so as to realize the basic control of parameters within the range of process equipment.

To sum up, the present invention has reasonable design, simple structure, high degree of automation, low labor intensity, and good cleaning effect of hemp silk.

detailed description

As shown in Figure 1, the hemp shred removal and separation device in the tobacco stem of the present invention comprises a support 1, and the winnowing box 2 is provided on the support 1, and the top of the front side of the winnowing box 2 is provided with a feed port 3, and the winnowing box 2 The air inlet 4 is arranged on the front side, the throwing roller 5 is arranged in the winnowing box 2, the air outlet pipe 6 is arranged on the top of the winnowing box 2, and the butterfly valve 7 for controlling the air flow is arranged on the air outlet pipe 6, and the top of the winnowing box 2 A hemp cleaning mechanism is arranged between the air outlet pipe 6 and the lower end.

The hemp silk cleaning mechanism includes a motor reducer 8, a driving roller 9, a driven roller 10, an air knife 11, a brush roller 12, a scraper 13, a hopper 14 and an annular mesh belt 15, and the power output end of the motor reducer 8 One end of the driving roller 9 is connected in transmission, and the driving roller 9 and the driven roller 10 are connected by a mesh belt 15. The mesh belt 15 is arranged horizontally and is located at the connection between the winnowing box 2 and the air outlet pipe 6. The discharge hopper 14 Located on the side of the air separation box 2, the air knife 11, the brush roller 12 and the scraper 13 are all located directly above the drop hopper 14, the air knife 11 is located between the upper half and the lower half of the mesh belt 15, and the air knife 11 The air outlet of the air outlet is towards the lower half of the mesh belt 15, and the brush roller 12 and the scraper 13 are arranged below the lower half of the mesh belt 15, and the upper sides of the brush roller 12 and the scraper 13 are all connected to the lower half of the mesh belt 15.
