Abstract

The utility model relates to a repeatedly-torn fiber opener, which comprises a material feeding box, a gear roller, a material discharging dust cage and a machine frame. Compared with the prior art, the utility model is characterized in that the gear roller adopts a high-speed gear roller; a repeatedly-torn plate corresponding to the gear roller is arranged below a material feeding roller in the material feeding box. The utility model has the advantages that a plurality of times of tearing and opening with one-time material feeding is realized; opening rate is above 99%; compared with the existing equipment, the output of one machine is increased by 2.5 to 3 times; the energy consumption of the utility model is only about 70 % of the existing equipment.

Description

Repeatedly-torn fibre opener

The utility model relates to the preliminary treatment of natural or artificial fibre, is a kind of opening picking equipment that uses the dentation instrument.

The PP cotton fiber in toy industry, the sector application of cotton-wadded quilt source mill more and more widely, the demand to the shredding equipment of PP cotton fiber also enlarges gradually thus.Existing P P cotton fiber shredding equipment all is a tearing type fiber opening machine basically, and it is made up of feed box, discaling roll, discharging dust cage and frame etc.Feed roller in the main dependence feed box and the speed difference between the discaling roll realize a tearing to the PP cotton fiber.Yield poorly, shredding weak effect, energy consumption be big, general unit-hour output is 60-90Kg.The shredding rate between 95%-96%, the about 28KW of average power consumption per ton.Because PP cotton fiber price is higher, therefore in fact just do not increased the cost of products such as toy greatly by the PP cotton fiber of shredding, to the competitiveness of product in market, especially export competitiveness has been brought influence.

The purpose of this utility model provides a kind of output and shredding rate height, the repeatedly tearing type fiber opening machine that consumes energy low.

Technical solution of the present utility model is: a kind of repeatedly tearing type fiber opening machine, comprise feed box, discaling roll, discharging dust cage and frame, and the difference of itself and prior art is: discaling roll adopts the high speed discaling roll; The repeatedly tearing plate relative with discaling roll is housed below the feed roller in feed box.

Be processed with many toothrows on repeatedly tearing plate in the utility model face relative with discaling roll.Certainly, also can adopt other suitable structures.

The crown of many toothrows is arranged in order the formation arc surface on the repeatedly tearing plate in the utility model.Certainly, also can become other suitable shapes.

Tooth in the utility model is concentrated the latter half that is positioned at repeatedly on the tearing plate, and repeatedly the first half on the tearing plate is the bigger broken line shape of angle.Certainly, tooth also can adopt other suitable versions; Repeatedly the broken line shape of the first half on the tearing plate also the structure of available other suitable shapes substitute.

The utility model has the advantages that: owing to increased repeatedly tearing plate, and discaling roll speed height, realized a repeatedly tearing shredding of charging, shredding efficient is brought up to more than 99% from the 95%-96% of prior art, unit-hour output than the high 2.5-3 of prior art doubly, and the average power consumption of processing PP cotton per ton has only about 70% of prior art, has reached the good result of good quality and high output low consumption.To save the cotton raw material of PP of kiloton every year for country, the average price per ton of import PP cotton is about 14000 yuan at present, thereby increase income and economize on spending, strengthen competitive power of export for the industries such as toy of using the PP cotton good condition is provided, for country and enterprise will bring the ten minutes considerable economic.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structural representation of a kind of repeatedly tearing type fiber opening machine of the present utility model.

The repeatedly tearing plate member structural representation of Fig. 2 for adopting among Fig. 1.

Fig. 1 has described an embodiment of the present utility model.Formed feed box by many anistree feeding rollers 2 and upper and lower feed roller 4,3, casing 1 etc., also comprised discaling roll 6, discharging dust cage 9, frame 10 of forming by wallboard, spacer, driving member and guard shield etc. etc.In frame 10, also be equipped with every air knife 7, cross parts such as guidance tape 8, drip feed plate 11, motor 12.With the maximum difference of existing similar equipment be: a repeatedly tearing plate 5 is housed.Discaling roll 6 is cylindrical rollers made from metal material, at the outer peripheral face of the roller helicla flute of having got on the bus, has inlayed the zigzag tooth bar in groove.Repeatedly the shape of cross section of tearing plate 5 as shown in Figure 2, it is to process an arc surface (corresponding with discaling roll 6) on a metallic plate, reprocesses out many toothrows again on arc surface.The crown of many toothrows is arranged in order and has also just constituted arc surface.

The operation principle of the foregoing description is: starting motor 12, discaling roll 6 is rotation (about 1400 rev/mins) at a high speed thereupon under the drive of driving member, make anistree feeding roller 2 and last by machine driving again, following feed roller 4,3 and discharging dust cage 9 rotate together, after the PP of not shredding cotton is put into feeding casing 1, send into feed roller 4 up and down by anistree feeding roller traction, traction is held between 3, when these material run into the discaling roll 6 of rotation at a high speed, held by the zigzag hook of high-speed motion on the discaling roll 6, produced speed differential tearing shredding (being same as prior art substantially) for the first time, draw under the effect at the hook of discaling roll 6 through the fiber after the tearing shredding for the first time and to make the high speed circular motion with discaling roll, when running to repeatedly between tearing plate 5 and the discaling roll 6, produced repeatedly speed differential tearing shredding again, by behind the tearing plate 5 repeatedly, fiber is under the acting in conjunction of the air-flow of discaling roll surface high-speed motion and centrifugal force, thrown to discharging dust cage 9 along crossing guidance tape 8, delivered to equably on the drip feed plate 11 continuously with the rotation of discharging dust cage 9 rotating cylinders attached to the fiber on discharging dust cage 9 wire sides and skid off outside the machine.Air-flow every 7 pairs of discaling roll 6 surperficial high-speed motions of air knife played certain guide effect, solved the part fiber is drawn back into discaling roll 6 tops with air-flow problem.
