Description

Lossless uniform feeding storage feeder

Technical Field

The utility model belongs to the technical field of tobacco processing, concretely relates to harmless even pay-off storage feeding machine.

Background

The existing storage feeding machine is mainly used in a tobacco shred production line, is matched with a metering tube, an electronic belt scale or other equipment for use in order to meet the process flow requirements of shred production equipment, has the functions of caching and lifting materials, and achieves the purposes of constant material flow and uniform conveying.

The storage feeder used at present mainly comprises four parts, namely a storage box, a steep-angle conveyer belt, a material homogenizing roller, a discharge hopper and the like.

The storage box has the function of temporarily storing materials conveyed by the previous process or conveyed by the auxiliary material travelling crane. The belt type structure is adopted, and the belt type structure mainly comprises an active roller assembly, a passive roller assembly, left and right and tail frame wallboards, head loosening rollers and the like, wherein the requirements of different workshop sections are met. The material storage box bottom belt is driven to move by a shaft-coupled speed reducing motor.

The steep-angle conveying belt is mainly used for lifting and conveying materials, adopts a frame split side chain type chain for conveying, is provided with a turning horizontal section at the upper part and the lower part, and particularly comprises an upper head section, a middle section, a lower tail frame, a buffer bin, a conveying (chain) belt, brakers, a supporting frame and the like. The steep-angle conveying (chain) belt is driven to move by a coupling frequency-conversion speed-regulation speed-reduction motor positioned at the upper head section.

The material homogenizing roller is a control part of the thickness of a material loading layer of the steep-angle conveying belt of the feeding machine. The material-raking device mainly comprises a roller wheel height adjusting device, a material-raking roller, a material-poking rake roller and the like, wherein the thickness of a material layer is controlled by adjusting the distance between the material-equalizing roller and rake nails on a steep-angle conveyor belt, and the material-raking roller is driven to move by a shaft-coupled speed-reducing motor.

The discharging hopper is a discharging part of the feeding machine and is used for conveying materials of the steep-angle conveying belt to the lower-stage process equipment through the discharging hopper. The upper flange is connected with the upper head section of the feeder, and the lower flange is connected with a metering pipe or other equipment of downstream equipment.

When the storage feeding machine works, firstly incoming materials of the upper process are filled in the storage box through the conveyor or the auxiliary material travelling crane, and material caching is realized. The tail part of the material storage box is provided with a high and low material level photoelectric switch. When the material is piled up to storage tank afterbody high material level photoelectric switch and is sheltered from by the material, storage tank foot strip starts to move forward, and when storage tank afterbody low material level photoelectric switch was not sheltered from by the material, storage tank foot strip bring the shutdown. Upstream equipment continues the feeding, and the high material level photoelectric switch of storage case afterbody is sheltered from by the material once more, and storage bottom of the case area restarts the operation forward, so circulate until storage headstock head material level photoelectric switch shelters from by the material, accomplishes storage case material buffer memory. In order to solve the problem of material agglomeration and loosening, an upper layer and a lower layer of loosening shifting rollers are also arranged above a conveying belt of a storage box at the head of a storage box. When the device works normally, the upstream device stops feeding after the high material level photoelectric switch at the tail part of the storage box is shielded by the material for a certain time until the high material level photoelectric switch at the tail part of the storage box is not shielded by the material, and the upstream device continues to feed the storage box.

When the material level photoelectric switch at the head of the storage box is shielded by materials, the steep-angle conveying belt and the material homogenizing roller are started, and the steep-angle conveying belt starts to lift the materials. The storage bottom belt is started immediately, the storage bottom belt supplies materials to the steep angle conveyer belt until the photoelectric switch of the material level of the buffer bin at the lower part of the steep angle conveyer belt is shielded by the materials, and the storage bottom belt stops, namely the storage bottom belt stops supplying materials. And when the material level photoelectric switch is not shielded by the material in the buffer bin at the lower part of the steep angle conveying belt, the bottom belt of the storage box is started again, and the bottom belt of the storage box supplies the material to the steep angle conveying belt. The material storage box bottom belt is fed intermittently and step by step in such a circulating way, and the steep-angle conveying belt is ensured to feed continuously. When the materials on the steep-angle conveying belt pass through the material homogenizing roller, the materials higher than the set thickness are downwards stirred back by the material stirring roller of the material homogenizing roller, and the materials passing through the material homogenizing roller form a continuous material flow with uniform thickness on the steep-angle conveying belt, so that the purpose of constant-flow discharging is achieved.

However, since the storage feeder is required to be a constant flow delivery function, a storage bin is necessary to store the material for material buffering. The cache breaks through the relation of continuous feeding, and the material is taken to a relatively static state dynamically in the material conveying process, or the material is taken to a high material layer by being conveyed fast in the low material layer. The following operating states occur: firstly, when the storage bottom of the case area moves with the steep angle conveyer belt simultaneously, the thickness of the material of depositing on the storage bottom of the case area is greater than the material thickness on the steep angle conveyer belt far away, and the material is detained out from thick material heap side bottom through the rake nail, and the bottom material is detained on the rake nail. One part of the upper surface material is lifted upwards by the lifting action of the harrow nails when raking the material, and is brought to a certain height to collapse under the action of gravity, and the other part of the super-thick redundant material is directly pulled down by the harrow roller controlled by the thickness of the material layer of the material homogenizing roller. Because the thickness of the materials stored on the bottom belt of the material storage box is much higher than that of the materials on the steep-angle conveying belt, the surplus materials pulled down by the material equalizing roller are also much. The materials are conveyed upwards, the materials with the thickness higher than the set thickness collapse under the action of gravity, and the material homogenizing roller harrow stick is pulled down. The material is lifted up again and then pulled down again, and the process is repeated. The rake nails are buckled out and the rake rod is pulled down to damage and break the materials. Secondly, when the steep-angle conveyer belt moves upwards, the bottom belt of the storage box moves in a step-by-step mode of stop and go, a certain belt height difference exists between the two belts, the bottom belt of the storage box does not supply materials at a constant speed, and the materials are supplied from the bottom belt at a high position to the steep-angle conveyer belt at a low position in a step-by-step mode. The high material layer is also collapsed by free falling gravity, and the excessive material with super thickness is pulled down by the material homogenizing roller rake, lifted up by the steep-angle conveyer belt and pulled down again, so that the material is repeatedly rolled in the buffer area. Thirdly, incoming materials at the upper section of the storage feeder are fed through a box turnover machine, and the materials are agglomerated. The head of the material storage box is provided with an upper group of loosening shifting rollers and a lower group of loosening shifting rollers, and the loosening shifting rollers loosen the material and then supply the material to the steep-angle conveying belt. The rake rod fixed at the material outlet can stir the materials all the time, and the lifted excessive materials can be lifted up and collapsed, and the material-homogenizing roller rake rod can be pulled down, then the materials can be lifted up and pulled down by the rake nails on the steep-angle conveyer belt, and the materials can be repeatedly rolled.

The materials are conveyed to be lifted up through the rake nails on the steep-angle conveyor belt, redundant materials collapse due to gravity and are pulled down by the rake rods of the material homogenizing roller, then the materials are lifted up through the rake nails on the steep-angle conveyor belt, and are pulled down again, and the materials are repeatedly rolled. The materials are directly crushed by the aid of the rake nails after being buckled out and the rake rod is pulled down, and the movement phenomenon of crushing is repeated for more than ten times. Even if the material is not completely crushed, the material is also damaged, the processing resistance is reduced, and the crushing rate is increased for the subsequent procedures. The produced dust pollutes the production environment, the broken filament rate is increased, the whole filament rate is reduced, the filament consumption rate is increased, and the manufacturing cost is increased. But also seriously affect the inherent quality of the cigarettes.
