Abstract

An improved cotton fiber purifier is composed of a rack roller and a trash blade, wherein the trash blade is in arc shape arranged under the rack roller. The utility model has high trash removing efficiency, which can reduce block fallen cotton of discharged trash, to completely clean the large foreign material in cotton fiber and small foreign material adhered on fibers, to improve purification quality of cotton fiber.

Description

Modified cotton fiber defecation machine

1, technical field

The utility model relates to a kind of cotton processing equipment, specifically a kind of modified cotton fiber defecation machine.

2, technical background

The tooth bar drum-type cotton fiber defecation machine of selling on the market mainly comprises cotton linter defecation machine and life cotton for wadding defecation machine in infertile unginned cotton defecation machine of cotton ginning mill's cotton ginning and the production of cottonseed stripping suede now.These several equipment divide the branch that single cylinder and twin-roll are arranged by the number of every equipment cylinder, but its structure and principle are similar, and its structure and operation principle are representative.Its operation principle is: contain assorted fiber by the feeding railway carriage or compartment, give a pair of feeding roller (or giving drawing-in device) with hello a cotton roller and a feed plate, and then the tooth bar cylinder of feeding high speed rotation, the tooth bar cylinder contains the combing of loosening of assorted fiber to these, because the physical property of impurity and fiber is different, fiber is big to the adhesive force of sawtooth point, impurity is little to the adhesive force of sawtooth, the proportion of fiber is little, and the ratio of impurity is great, so fiber is also just different with the centrifugal force that impurity is produced.Impurity and by the block fiber that fully divides comb under action of centrifugal force, before the impurities removal adjustable plate, roll surperficial tangential direction by the airflow layer of dishing out along tooth, falling assorted district.And be dispersity by the single fiber of fully combing, and enter into the cotton road of collection with airflow layer, be adsorbed on the cotton dust cage of collection of rotation, wind is then siphoned away by air-introduced machine by the mesh that collects cotton dust cage, and here fiber has been realized separating with wind.And be mixed in the big impurity that contains in the assorted fiber, and a part has been fallen the district that falls to mixing, and (being separated by baffle plate) is discharged from, and some is then fallen in the cotton road of collection by row.

By use these years, there is following wretched insufficiency in the said equipment:

A, not big by the block fiber content of fully combing in falling to mixing, fiber loss is many.

Contain a considerable amount of big impurity and a part of fine impurities that sticks on the fiber in the cotton fiber behind b, the defecation.

Cause the reason of this wretched insufficiency as follows:

1, owing to cover plate and impurities removal adjustable plate under the cotton road of collection are one, their position is too near to feeding roller, cause impurities removal region alpha angle too little, some big impurity is fallen collection cotton road and fiber by row again and has been mixed in together, causes in the cotton fiber behind the defecation to contain the big impurity of part.

2, the gap of impurities removal adjustable plate and tooth bar cylinder is bigger than normal, and this kind equipment adjusting range requires all at the 15-60 millimeter on the market, and the cotton fiber after being in impurities removal adjustable plate under this big gap tooth bar cylinder hook being drawn can not play holding and scrape the stripping effect.In addition, in the assorted regional extent in α corner, holding is not set yet and scrapes fiber stripping and tie up device, cause fall to mixing in block cotton content many, the fine impurities that adheres in the cotton fiber behind the defecation is also many.

3, summary of the invention

The purpose of this utility model provides a kind of block noil that can reduce in the impurities removal, can remove big impurity and the fine impurities that sticks on the fiber in the cotton fiber more up hill and dale, can obviously improve the modified cotton fiber defecation machine of the defecation quality of cotton fiber.

The purpose of this utility model realizes in the following manner, the bottom of tooth bar cylinder camber install one to several impurity-discharging knife, under the situation that has impurity-discharging knife to exist, contain tooth bar cylinder that assorted fiber rotated at a high speed divide comb hook up after, by impurity-discharging knife the time, occurred at following 3 and obviously changed:

1, these impurity-discharging knifes have been held and have not been subjected to fully dividing comb and the cotton piece of desire whereabouts, these cotton pieces have been increased again be subjected to the chance that the tooth bar cylinder divides comb to hook up for several times, this has not only reduced block noil effectively, and the fine impurities in these cotton pieces and big impurity also have been subjected to scraping stripping and being eliminated of impurity-discharging knife.

2, impurity-discharging knife can holding be lived those single fibers that is subjected to fully dividing comb, and can scrape and peel those off and stick to fine impurities on these single fibers.

3, because the increasing at interval angle of falling to mix, centrifugal force all can be fallen assorted district more than the big big impurity overwhelming majority of fiber, can not fall in the cotton road of collection again and the cotton fiber behind the defecation mixes and arrives together.

Accompanying drawing is the structural representation of modified cotton fiber defecation machine.

4, description of drawings

With reference to Figure of description to below the improved machine for removing contaminant in cotton fibre Zuo of the present utility model in detail Bright.

Improved machine for removing contaminant in cotton fibre of the present utility model, as shown in drawings, its structure is that the You tooth bar rolls Tube 1 and impurity-discharging knife 2 consist of, and impurity-discharging knife 2 is the below that camber line is arranged on tooth bar cylinder 1.

5, embodiment

Its processing and fabricating of modified cotton fiber defecation machine of the present utility model is very simple and convenient, and the by specification accompanying drawing is shown in to be improved on original general cotton defecation equipment and makes.

Improved machine for removing contaminant in cotton fibre of the present utility model is compared with existing technology, and has overcome existing tooth The inefficient drawback of bar drum-type machine for removing contaminant in cotton fibre cleaning Za Zhi. Thereby, have reasonable in design, knot Structure is simple, be easy to process, easy to use, impurity elimination efficient height, the bulk that can reduce impurities removal Zhong fall Cotton can be removed more up hill and dale the big Za Zhi of cotton fiber Zhong and Nian and is attached to fine impurities on the fiber, energy Obviously improve the characteristics such as defecation Zhi amount of cotton fiber, thereby, have good value for applications.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.

Claims (1)

1. modified cotton fiber defecation machine comprises tooth bar cylinder and impurity-discharging knife, it is characterized in that impurity-discharging knife is the below that camber line is arranged on the tooth bar cylinder.
