Abstract

A kind of cellulose acetate uniform drying conveying distribution device, including oscillating deck, balance staff and balance staff swing mechanism, oscillating deck are mounted on balance staff, and balance staff is connect with balance staff swing mechanism.The balance staff swing mechanism, including gear, rack and rack push-pull mechanism, gear are mounted on the balance staff, and rack connect with rack push-pull mechanism and engaged with gear.Whole device is mounted on the roll feed conveyer top in four-roller machine equipment, and balance staff swing mechanism drives balance staff rotation, oscillating deck up and down reciprocatingly to be swung with balance staff.Material is fallen first to be swung with oscillating deck and is uniformly dispersed on oscillating deck, and roll feed conveyer is progressed into, and realizes uniformly conveying cloth.The device make material can only could be even into four-roller machine when material is few, few phenomenon when avoiding more when roll charging ensures that material conveying average rate is unobstructed, and can control the inlet amount of each period by controlling balance staff swing mechanism.

Description

Cellulose acetate uniform drying conveys distribution device

Technical field

It is uniformly defeated when the utility model is related to one kind in cellulose acetate production process for cellulose acetate flake drying The device of work feed material belongs to cotton pulp and shreds technical field in advance.

Background technology

Cellulose diacetate (abbreviation vinegar sheet) is to make acetylizing agent, vinegar with aceticanhydride using high-purity bleached dissolving pulp as raw material Acid makees solvent, and under catalyst sulfuric acid effect, acetylation is carried out to wood pulp cellulose, by hydrolysis, precipitating, washing, extruding, does The processes such as dry are produced.Specifically production process is：Wood pulp by crushing stirs in preprocessor together with acetic acid, then Acetifier is sent into carry out reacting generation Triafol T with nitration mixture；It is passed through low-pressure steam after reaction, is added a certain amount of Spirit of vinegar, hydrolysis generation cellulose diacetate (vinegar sheet) under the conditions of existing for sulfuric acid；Again through precipitating, washing, extruding, drying etc. Process obtains product vinegar sheet.

The cellulose diacetate generated is hydrolyzed, is needed dry by being delivered to drying machine after roll pressed in four-roller machine equipment Dry, material (cellulose diacetate) enters roll by roll feed conveyer.In actual mechanical process, into the material of roll When it is more when it is few, when material is excessive, can not disposably enter roll since channel is narrow, roll cannot in time convey material It goes out, excessive feed blocking causes load excessive between roller and bearing, occurs to jump vehicle phenomenon.Service personnel needs to tear open Roll is examined, clears up extra material, then return dress, needs the time in this way.In this course, product conveying is interrupted, and cannot get Drying is squeezed in time, causes to waste.

Invention content

When the utility model is dried for cellulose acetate flake existing feeding technology there are the problem of, a kind of structure letter is provided It is single, securely and reliably, it can realize the cellulose acetate uniform drying conveying distribution device of uniform distribution.

The cellulose acetate uniform drying of the utility model conveys distribution device, using following technical proposals：

The device, including oscillating deck, balance staff and balance staff swing mechanism, oscillating deck are mounted on balance staff, and balance staff is put with balance staff Motivation structure connects.

The balance staff swing mechanism, including gear, rack and rack push-pull mechanism, gear are mounted on the balance staff, tooth Item connect with rack push-pull mechanism and is engaged with gear.

The rack push-pull mechanism uses cylinder, oil cylinder or electric cylinders.

Whole device is mounted on the roll feed conveyer top in four-roller machine equipment, and balance staff swing mechanism drives balance staff to turn Dynamic, oscillating deck is up and down reciprocatingly swung with balance staff.Material fall first on oscillating deck with oscillating deck swing and is uniformly dispersed, gradually into Enter roll feed conveyer, realizes uniformly conveying cloth.

The utility model be mounted on extrusion equipment four-roller machine roll feed conveyer top, make material enter roll into During expecting conveyer, it is squeezed, it can only could be even into when material is few when material is very more Four-roller machine, few phenomenon when avoiding more when roll charging ensure that material conveying average rate is unobstructed, and can be by controlling balance staff pendulum Motivation structure controls the inlet amount of each period.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model cellulose acetate uniform drying conveying distribution device.

Fig. 2 is the vertical view of Fig. 1.

In figure：1. oscillating deck, 2. swinging axles, 3. gears, 4. racks, 5. cylinders.

Specific implementation mode

As depicted in figs. 1 and 2, the cellulose acetate uniform drying of the utility model conveys distribution device, and structure is simpler It is single, including oscillating deck 1, balance staff 2 and balance staff swing mechanism.Oscillating deck 1 is mounted on balance staff 2, and balance staff 2 connects with balance staff swing mechanism It connects.Whole device is mounted on the roll feed conveyer top in four-roller machine equipment.Oscillating deck 1 is mounted on balance staff 2, balance staff pendulum Motivation structure drives balance staff 2 to rotate, and oscillating deck 1 is up and down reciprocatingly swung with balance staff 2.Material falls straight on oscillating deck 1 first It tapping into roll feed conveyer, material swings with oscillating deck 1 and is uniformly dispersed, and progresses into roll feed conveyer, without It is to crowd into quickly, realizes uniformly conveying cloth, few phenomenon when avoiding more when roll charging ensures that material conveying is equal Speed is unobstructed

Balance staff swing mechanism uses rack and pinion mechanism, including gear 3, rack 4 and rack push-pull mechanism, gear 3 to install On balance staff 2, rack 4 connect with rack push-pull mechanism and is engaged with gear 3.Rack push-pull mechanism uses cylinder 5, can also be used Oil cylinder or electric cylinders etc..Cylinder 5 is mobile back and forth horizontally with carry-over bar 4, and rack 4 is with the reciprocally swinging within a certain angle of moving gear 3, pendulum Movable plate 1 is swung with balance staff 2.The inlet amount of each period can be controlled by the movement of control rack 4 simultaneously.

Claims (1)
