Can automatically add the griping cotton machine equipment of antistatic additive
The utility model relates to the griping cotton machine equipment in a kind of nonwoven production, the griping cotton machine equipment that particularly automatically adds antistatic additive and automatically control the addition of antistatic additive in a kind of dry method nonwoven production process.
In the production process of dry method nonwoven fabric, the interpolation of antistatic additive is an important link, because between the fibrous material or during the mutual friction of fibrous material phase, two articles generation electronics shifts, thereby easily produce static, the harm of static is very large in process of production: affect fibre forming and product quality, on the other hand, when the fiber lapping, thereby lapping fiber and fiber that will lapping are subjected to the impact of static to produce the randomness that attraction or rejection have affected the fiber lapping, cause the difference of whole product on structure and performance.In process of production, be accumulated in electrostatic pressure that the electrostatic charge of fiber surface produces more than 4kv, if the static that production process produces is not eliminated, run up to static discharge phenomenon generation electric spark to a certain degree will occur, villus fiber, all belong to inflammable thing the danger that causes fire is arranged, safety in production in serious threat; If the static that production process produces is not eliminated, also with certain static, add operating barriers such as can producing adhesion, discharge man-hour and absorption dust after carrying out on the manufactured goods, thus the production of processing after the impact.
In the production of present short fiber enterprise, mainly take to increase the humidity of environment, use some anlistatig materials in the production, be exactly the method such as interpolation antistatic additive in the process of raw material preparation with ining addition.Antistatic additive reduce static generation, accelerate static in and loss, or by above-mentioned both combine to eliminate static.What select in the dry method nonwoven fabric is the amphoteric surfactant that has simultaneously the yin, yang ion, and it has hygroscopicity, flexibility and antistatic behaviour, and the consumption of antistatic additive is 3-5%, evenly sprays into before short fiber enters into combination process.The consumption of antistatic additive surpasses 5%, and it is bad that product will carding effect occur in process of production, is entangled with agglomeratingly, and short fiber twines the roller phenomenon, so just directly affects production efficiency, and serious can also damage card clothing.
Summary of the invention
The purpose of this utility model focuses on the technical deficiency that solution is as above told, and has all added the requirement of the uniformity of antistatic additive and electrostatic agent thereby reach every layer fibrous raw material.
The utility model can add the griping cotton machine equipment of antistatic additive automatically, mainly comprises: telescoping tube, central shaft, be installed in dolly on the central shaft, grab cotton hired roughneck, inner ring wallboard, outer ring wallboard, rail; Its characteristics are: the lower end of described telescoping tube is provided with grabs cotton hired roughneck, and the top of grabbing cotton hired roughneck is provided with and is the shower nozzle that horizontal linear is arranged more than one, and described shower nozzle interconnects with the pipeline that is connected water pump by electromagnetic valve; Described water pump is connected with water tank.
The utility model can be controlled the sprinkling program of antistatic additive automatically according to the duty of griping cotton machine, and the duty of water pump is synchronized with the duty of griping cotton machine motor.When a whole set of machinery equipment operation, can be according to present situation automatic spraying antistatic additive, determine the operating frequency of water pump according to present situation, guarantee that the addition of antistatic additive of every layer of cotton of being caught away 3%-5%, has guaranteed that also every layer fibrous raw material has all added antistatic additive simultaneously.Namely guarantee the uniformity, also guaranteed addition.

The specific embodiment
Below in conjunction with description of drawings the utility model is further elaborated.
Fig. 1 is preferred version of the present utility model, and it has shown the griping cotton machine equipment that can automatically add antistatic additive, mainly comprises: telescoping tube 1, central shaft 4, be installed in dolly 2 on the central shaft 4, grab cotton hired roughneck 3, inner ring wallboard 5, outer ring wallboard 6, rail 7; Its characteristics are: the lower end of described telescoping tube 1 is provided with grabs cotton hired roughneck 3, and the top of grabbing cotton hired roughneck 3 is provided with and is the shower nozzle 8 that horizontal linear is arranged more than one, and described shower nozzle 8 interconnects with the pipeline that is connected water pump 10 by electromagnetic valve 9; Described water pump 10 is connected with water tank 11.Pump motor and the disc bale plucker of supply shower nozzle 8 hydraulic pressure link together, when disc bale plucker rotates, and starting working for water pump 10 on the shower nozzle 8.When griping cotton machine stopped, water pump 8 quit work immediately, simultaneously in the back of each shower nozzle, an electromagnetic valve 9 had been installed all, in the time of water pump 8 work simultaneously electromagnetic valve 9 open, when water pump 8 stopped, electromagnetic valve 9 cut out.So just guaranteed that ducted water outwards flows on the fiber because of self gravitation, has avoided adding static dosage when water pump 8 is idle.Simultaneously, according to measuring and calculating and experience, determine the operating frequency of water pump 8, so just guaranteed that the addition of antistatic additive of every layer of cotton of being caught away is at 3%---5%.Simultaneously guaranteed that also every layer fibrous raw material has all added antistatic additive.
