Technical Field

The invention relates to a cotton grabbing and mixing method and a cotton grabbing device of a spinning machine, in particular to a method for grabbing all mark ratios simultaneously in real time and a cotton grabbing machine adopting the grabbing method.

Background

The bale plucker is the first fiber processing machine in cotton spinning production, is also an important device for forcibly mixing fibers of all mark bales participating in cotton blending in a spinning process, and the subsequent spinning devices in a spinning process are used for randomly mixing the fibers. In the spinning production process technology, the construction of the uniform distribution of physical and appearance fibers in the yarn and the elimination or resistance of various unevenness are one of the most important tasks of spinning production, the improvement of various unevenness of the fiber distribution is the key importance of quality management, in various unevenness, the fiber mixing unevenness is a key and fundamental unevenness, and five unevenness in the spinning production and the mutual relations are listed in the attached figure 1.

The prior art plucker is widely applied to the blowing-carding process since the frameless reciprocating type automatic plucker is available, and various spinning machine manufacturers produce pluckers with the same size and different sizes all over the world without great change for decades. The prior plucker has almost no other additional functions except that the prior plucker meets the capacity requirement of plucking and supplying cotton in the opening and picking process.

Use current reciprocating type automatic bale plucker as an example, in the actual production application that cotton is mixed to multi-marker matching, the stroke that its whole marker ratio was snatched is a dress cotton platform length, even under work efficiency is 100%'s the condition, the cycle that whole marker ratio was snatched also needs several minutes. Or in another aspect, the grabbing of all the mark proportioning units can be finished only when the amount of the grabbed raw materials reaches dozens of kilograms. From the point of view of cotton blending, this is a significant drawback of the reciprocating automatic plucker, and this process step is mainly compensated by the random blending of the subsequent processes.

Reciprocating type automatic plucker snatchs once in a few minutes and forms, is flowing with the cotton volume of tens kilograms of gross weight as whole mark ratios of unit, just must carry out intensive mixing with such cotton volume in follow-up flow, makes all mark ratios distribute comparatively evenly. Because the cotton flow composed of basically the same components continuously flows into the subsequent flow, the cotton flow with incomplete proportion is mixed in the cotton mixing process and the cotton mixing machine (such as a multi-bin cotton mixer) in the prior art, and the mixing operation is carried out in a plurality of separated spaces of the cotton mixing machine with large cotton storage capacity by utilizing the time difference, the three-dimensional space difference and the separated space difference of the cotton flow entering the cotton mixing machine. The cotton storage capacity of a common multi-bin cotton mixer is hundreds of kilograms, which is about half an hour of cotton supply output of the cotton mixer, namely, the capacity in a cotton storage bin is about ten cotton flow of complete proportioning units. In order to mix the incomplete proportioning cotton flow into the cotton flow with complete proportioning at any segment as much as possible, cotton mixing machines with various modes for uniform mixing are provided, the cotton mixing scheme comprises simultaneous input and non-simultaneous output, bin-divided delay input and stepped output, random input and random output, random input and different speed (non-simultaneous) output, transverse paving input and direct taking output and the like, the cotton mixing process idea is emphasized, but no cotton mixing scheme can show special advantages and replace other cotton mixing schemes. The key point lies in the cotton mixing machine of random mixed mode, can't realize the mixing to the whole mark ratio of cotton piece level small weight unit, and processes such as subsequent cotton cleaning, comb and parallel cotton also all are random mixed mode in addition, rather than the mandatory mixing according to whole mark ratio.

Therefore, the existing cotton grabbing technology is in a forced mixing link, the proportion of the cotton block-level small-weight unit complete label and the mixing imperfection of the cotton block-level small-weight unit complete label are inherent defects of the existing cotton grabbing machine, the subsequent random mixing is difficult to eliminate, and adverse effects on the quality of semi-finished products and finished yarns are generated.

The alternate bale plucker with the ascending platform, the rotary bale plucker with the descending disk and the modern reciprocating bale plucker with the descending handle widely applied to the blowing-carding process are all non-real-time full label grabbing modes.

Even at the latest 2019ITMA international textile machinery exhibition, the innovative BO-P portal bale plucker firstly introduced by German Telitz corporation only increases the width of a bale plucker and 1-2 transversely arranged bales in the aspect of enhancing the cotton mixing function, and still belongs to a non-real-time full-label plucking mode.

Except that non-real-time full mark plucks cotton short board and the function singleness of mixing, current plucker still has: the occupied area is large and the area utilization rate is low; the cotton grabbing tower crane has large volume, heavy weight, high gravity center, cantilever operation and poor operation stability; the cotton flow conveying distance is long, and the conveying power consumption is large; the density difference of cotton bales at the bottom of the table top is large, and the discreteness of the weight and the size of a captured cotton block is large; has no defects of impurity and foreign matter removing function and the like.

Due to the inherent shortage of the first equipment in the spinning process, in order to meet the process requirements of opening, mixing, cleaning, carding and the like of the blowing-carding system, a plurality of equipment with single function can be added in the process, so that the whole opening-cleaning system has more single equipment and long process flow.
