JWF1276 Comber Is Well Designed To Greatly Improve The Quality Of Cotton Web.

< p > Jingwei Yuci branch has developed and produced Combing Equipment for nearly 30 years.

Products from the late 80s of last century FA261 to today's JWF1276 models have undergone six generations of upgrading, ranging from primary to advanced, from medium speed to high speed, from semi manual to full automatic.

At present, the main commercial models are JWF1272A, JWF1275 and JWF1276, which are suitable for different spinning varieties and different user groups.

The design clamp times of JWF1272A, JWF1275 and JWF1276 are 400 clamp / sub, 450 clamp / minute, 500 clamp / minute respectively. The output of single machine is 50 kg / h, 65 kg / h, 75 kg / h respectively, and the Xilin pmission adopts constant speed, variable speed and variable speed respectively. The running speed is 330 clamp / min, 350 clamp / min, 380 clamp / minute respectively.

The main performance characteristics of the combing machine < p > JWF1276 are: the clamp plate swing is reduced by 23%, the maximum acceleration of the clamp plate is reduced by 35%, the separation roller turnover is reduced by 16%, the maximum acceleration of the separation roller is reduced by 45%, and the speed is increased by 8%.

The machine adopts variable speed carding and accurate matching with the roller to achieve the elastic recovery of the lower pressure a href= "http://www.91se91.com/news/index_c.asp" > fiber > /a >; the brush cleaning time is lengthened and the short fiber impurity is avoided; the high sensitivity leakage protection device is installed to prevent the long detail defects of the spinning yarn; the touch screen displays the suction and negative pressure in real time and is convenient for monitoring and adjustment; the suction and noil integral air duct excludes the interference of the airflow to the cotton net under high-speed running, improves the movement coordination, improves the quality of the cotton net, reduces the fiber loss, and reduces the fiber loss by 3%.

The machine also selects the energy saving motor with variable frequency control; the optimized pmission mechanism reduces the size and eccentric radius of the connecting rod, the length of the force arm increases, reduces the power consumption by 6%; the tin forest shell and the clamp plate seat adopt new materials, reduce the impact inertia, reduce the load energy consumption under the same high tongs, redesign the air volume negative pressure, lower the dust power and reduce the energy consumption by 2% under the same car speed.

< p > drafting mechanism still adopts cast iron drafting wallboard according to long-term operation practice to ensure that the equipment runs at high speed.

The pmission form is driven by the tooth belt wheel power pmission, the mechanical mechanism is simpler and more stable, the equipment operates reliably, and at the same time, the process pformation and equipment maintenance are simplified and convenient.

The machine adopts three upper and three lower pressure bar drafting mechanisms, which can adjust the center distance between front, middle and rear rollers and the forward and backward movement of the adjustable roller relative to the rollers, which can expand the adjustment range of drafting distance in the drafting area, and adapt to different regions and grades of raw material varieties, especially adapting to the production requirements of shorter staple cotton fibers.

When spinning different fibers, by adjusting the position and distance of the middle and back rollers and the roller, the drafting distance and the pressure bar curve of the appropriate position can be changed, the binding angle between the fiber and the roller is changed, and the curve structure of the uniform delivery fiber is formed inside the fiber area, so that the uneven evenness of the cotton bar is effectively controlled.

The new draft cleaning system is used to change the structure of suction device and the material of cleaning parts, and adapt to a wider range of environmental conditions.

< p > due to the change of effective output length, the upper pivot of the cotton board has a certain forward angle.

The overall design of the guiding board is flexible, and the tension radian is increased correspondingly, so that the time of changing the roll joint is reduced, the quality is improved, the work intensity of the car Block personnel is reduced, the width of the cotton sheet is tightened, the effective working area of the roller is lengthened, and the requirement of the multi region and multi quality condition of the raw cotton is prolonged. The utility model can maintain the good condition of the cotton net in the different temperature and humidity environment; the roller adopts an electrostatic induction structure, while simplifying the design, improving the firmness without any maintenance at any time; the pressure plate spring is arranged on both sides of the clamp plate, and the rigidity improvement is carried out, so as to ensure the long-term stability and improve the accuracy and stability of the clamp plate in high-speed operation.

< p > according to the pmission force characteristics and structural characteristics of the machine, the key points in the design and application of the gear shifting mechanism are in-depth research and continuous improvement in the aspects of tooth profile modification, < a href= "http://www.91se91.com/news/index_f.asp" > raw material < /a > process analysis and processing equipment application.

In view of the design of rotating components in cars, such as cylinder shell, clamp plate seat, etc., while adopting new lightweight materials, the circular motion structure and three-dimensional dynamic balance are reanalyzed. The new material and dynamic balance are effectively combined to reduce the impact inertia of the machine, thus laying a good foundation for higher speed operation.

The improvement of the structure of the motor belt pulley eliminated the < a href= "http://www.91se91.com/news/index_x.asp" > belt < /a > and wheel system damage caused by operational errors, and the cotton face plate and cotton bar detection device were constantly improved.

< p > in addition, the separation of roller, nipper balance and pmission chain mechanism of the JWF1276 comber further improve the impact resistance of the swinging parts and reduce the inertia and acceleration of the equipment.

For example, the pmission box and supporting frame structure adopt high intensity design as a whole, which realizes high speed running condition with stable noise reduction; the overall rigidity of wallboard design is increased, and the center of gravity is reduced; it has good static and dynamic accuracy, vibration is stable in high speed operation, the corresponding weight of key rotor parts in vehicle is reduced, and the impact force of machine parts is lower.

< p > overall, the machine adopts long cotton feeding, strong combing, low droppings and heavy weight process configuration, and the production capacity is obviously improved.

It pays great attention to high speed and high yield, at the same time, pays more attention to the improvement of technological efficiency, improves carding quality, reduces cost consumption, and makes convenient manual operation. At the same time, it pays more attention to efficiency and automation while paying attention to high speed and high output.
