The invention relates to the technical field of textile equipment, in particular to a straightening and leveling device of an automatic cotton and hemp stalk feeding machine and an application method thereof.
Background
Cotton stalks are main byproducts and residues of cotton, and the cotton fields in China are about eight thousands of mu. The total biological amount of cotton stalks is about four tens of millions of tons throughout the year, wherein about 2750 mu of cotton stalks are produced in Xinjiang, about 200 kg of cotton stalks are produced in a unit way, and about 600 ten thousand tons of cotton stalks are produced in a unit way; about 2000 ten thousand mu in Yangtze river basin, about 850 kg/mu of cotton stalk per unit yield and about 1700 ten thousand tons of cotton stalk yield; the yellow river basin is about 2700 mu, the cotton stalk unit yield is about 600 kg/mu, and the cotton stalk yield is about 1620 ten thousand tons.
Cotton stalks are annual semi-woody plants, and the anatomical form, chemical composition, physical properties and the like of the cotton stalks are similar to those of soft broad-leaved forests. The cotton stalk core is wood fiber, accounting for about 66% of the weight of the cotton stalk, the fiber form is better than that of the populus euphratica, and can be compared with the fast-growing populus euphratica in broad-leaved forest, thus being a good raw material for paper making, charcoal making, fiber making board making, bioethanol fuel making and the like. Cotton stalk barks are bast fibers, account for about 22% of the weight of cotton stalk, and have the characteristics and style of hemp fibers: 1) Is a typical degradable environment-friendly biological material; 2) The moisture absorption and dissipation speed is high, the air permeability is excellent, and the ecological temperature environment on the skin surface of a human body can be timely regulated; 3) The antibacterial and bacteriostatic properties and the sanitation are good; 4) The ultraviolet resistance is strong, and the radiation protection effect is also realized; 5) The fabric is stiff, smooth and has good drapability, and is a natural textile material.
The cotton root bag and waste plastic (waste mulching film) can be processed into wood plastic products such as logistics trays, outdoor tables and chairs, floors and the like. Crushing cotton boll shells, leaves and fine branch tips to obtain feed for ruminants (cattle, sheep and horses). The cotton byproducts are all treasures and are sustainable renewable resources.
However, the cotton stalk is very difficult to separate from the skin and the core, the labor intensity of the manual peeling mode is too high, the labor efficiency is extremely low, the industrial feasibility is not realized, and tens of millions of tons of cotton byproducts can not be comprehensively utilized each year to form agricultural wastes. The invention patent ZL200710034304.X applied by the applicant and 2007 opens the way for mechanical separation of cotton stalk skin and core. However, the table throughput of the cotton stalk bark-core separator in the patent is only 54 kg of cotton stalks, and the yield and quality of cotton stalk bark-core separation still need to be further improved.
In order to greatly improve the yield and quality of the cotton stalk bark-core separator, cotton stalks must be arranged in a single row and directly enter a bark-core separation working area. Some nonstandard cotton stalks can exist in cotton stalks which are uniformly straightened and move forwards side by side in a single row, and in order to separate the skin and the core of the cotton stalks better (vertical striking), the straightened and flattened cotton stalks need to be straightened and flattened, so that a more ideal state of regular single row side by side and straight is formed.

Example 1
Referring to fig. 1, 2 and 6, a straightening and leveling device 40 of an automatic cotton and hemp stalk feeder according to an embodiment of the present invention is applied to an automatic cotton and hemp stalk feeder, and is mainly used for straightening and leveling cotton and hemp stalks which are straightened uniformly to form cotton and hemp stalks which are in a single row and move forward straight side by side.
As can be seen in fig. 1, 2 and 6, the straightening and flattening apparatus 40 includes a third pin drive chain row 41, a front roller press roller 42 and a rear roller press roller 43. The third corner nail transmission chain row 41 is horizontally arranged along the feeding direction of the cotton and hemp stalk automatic feeding machine, and a third corner nail 411 for pushing the cotton and hemp stalk to advance along the feeding direction is arranged on the third corner nail transmission chain row 41; the front roller press roller 42 is rotatably arranged on the frame 10 and is positioned above the third corner nail transmission chain row 41, and a gap for single-layer cotton and hemp stalk to pass through is formed between the front roller press roller 42 and the third corner nail transmission chain row 41; the rear roller press roller 43 is rotatably mounted on the frame 10, the rear roller press roller 43 is positioned behind the front roller press roller 42 and above the third corner nail transmission chain row 41, and a gap for single-layer cotton and hemp stalk to pass through is formed between the rear roller press roller 43 and the third corner nail transmission chain row 41.
By adopting the straightening and leveling device 40, cotton and hemp stalks which are straightened uniformly are conveyed to the third corner nail transmission chain row 41 from the second corner nail transmission chain row 31 in a single row, and the running speed of the third corner nail transmission chain row 41 is appropriately greater than that of the second corner nail transmission chain row 31; the linear speed of the upper front roller press roller 42 and the rear roller press roller 43 is consistent with the running speed of the third corner nail transmission chain row 41; after the single-row side-by-side cotton and hemp stalks enter a control area (namely a gap between the front roller press roller 42 and the third corner nail transmission chain row 41) formed by the front roller press roller 42 and the third corner nail transmission chain row 41, the cotton and hemp stalks can rapidly advance at the running speed of the third corner nail transmission chain row 41, and the cotton and hemp stalks possibly not standardized in the single-row side-by-side cotton and hemp stalks are straightened under the action of the front roller press roller 42; after entering the control area (i.e. the gap between the rear roller press roller 43 and the third corner nail transmission chain row 41), cotton and hemp stalks are straightened further. After twice straightening, the cotton and hemp stalks basically form a more ideal state of regular single row side by side straightening, which creates necessary preconditions for the subsequent pre-pressing or extrusion of the cotton and hemp stalks and the smooth separation of the cotton and hemp stalk skins and cores.
