< p > in order to solve the practical problems such as the current a target= "_blank" href= "//m.pmae.cn/" > textile < /a > enterprise recruitment difficulties, high labor costs and labor intensity, Shaoxing's automation equipment technology has been studying for 6 years by the company, and has done a lot of analysis and Research on traditional doffing and automatic doffing. Finally, the JZAD485 automatic doffer has been successfully developed.

< /p >

< p > this machine has created a new doffing mode between mobile and fixed sets, which can be freely adapted to all kinds of spinning frames.

< /p >

< p > according to Wang Guogao, general manager of the company, the machine is mainly composed of an intelligent carrier and two automatic pipe doffing trolley, which can replace manual operation in fixed areas, and realize automatic pipe management, automatic extubation, automatic pipe insertion and management of doffing work of many spinning frames.

The advantage of the doffing technology lies in: on the one hand, it integrates the U-turn management, the extubation and the intubation, so that the pipe alignment process is completed in the dynamic process, greatly reducing the process and the work saving time. On the other hand, the doffing carrier can realize the automatic pportation of two Downer doffing cars and realize the wireless connection.

At present, the JZAD485 automatic doffer has obtained 4 national invention patents and 7 utility models patents. At the same time, it has obtained 1 national level projects, 1 provincial and 2 municipal level projects.

< /p >

Compared with the automatic doffing machine popularized at home now less than a href= "//m.pmae.cn/news/index_s.asp" > market < /a > < p >, the JZAD485 automatic doffer mainly has the following 5 characteristics: first, the mother machine structure, remote control operation.

Single person can finish many processes such as pipe management, extubation and intubation of many spinning machines, reducing labor and reducing labor intensity.

The two is the integration of management and doffing.

Each automatic tube doffing car has functions of automatic pipe management, automatic extubation and automatic intubation. The pipe is completed in the dynamic doffing process, shortening the production link and improving the production efficiency.

The three is the pre loosening function of the bobbin, which ensures that the success rate of yarn pulling for any colored spindle and bobbin is over 99%, prolonging the service life of the spindle and bobbin, and greatly reducing the material consumption of the machine.

The four is the function of leaving the tail yarn.

By using special mechanism and specific process means, the retention rate can be raised to over 105% of hand doffing.

The five is self adjustment function.

The damage of the automatic doffing car to the evenness of the spinning frame is reduced, so as to ensure the normal running of the downer car in the dynamic environment of different workshops.

< /p >

< p > Wang Guogao also used a set of data to introduce to reporters the effect of JZAD485 automatic doffer in the practical application of enterprises: Taking spinning 40 S yarn as an example, the 10 thousand spindles production capacity should be equipped with 12 doffing workers (3 classes / days); after applying the automatic doffer, only 3~5 position managers should be provided, and the number of workers will be reduced by more than half.

The average daily expenses of enterprises are reduced by 643 yuan, which can generate 231 thousand and 480 yuan a year for enterprises, and the investment cost of equipment can be recovered within two years.

< /p >

< p > in addition, after the JZAD485 automatic doffer is equipped, the efficiency of the spinning production equipment can be greatly improved.

Preliminary calculations show that the working time of each doffer is reduced by 20% to 50% compared to the traditional manual and semi-automatic doffer.

At the same time, the application of JZAD485 automatic doffer can also reduce the consumption of machine material and so on.

The traditional manual pulling out of the tube is directly lifted from the cone, which is easy to pollute the damaged yarn and spindle. The automatic doffer machine can effectively avoid this problem.

< /p >

< p > at present, the automatic doffer machine produced by the < a href= "//m.pmae.cn/news/index_c.asp" > the current company < /a > has been trial run for two years in Shijiazhuang Changshan stock company, and the products have been put in small quantities in Fujian, Jiangsu, Shandong and other markets.
