The JSL series is expensive, difficult to maintain and costly (about 6,000 yuan per maintenance fee). In recent years, we have used the JSL series of electronic length gauges to modify the length gauges of these devices, which has improved the automation of the original equipment. Productivity.
1The principle block diagram is the principle block diagram of JSL-I type electronic length gauge; it is the principle block diagram of JSL-type electronic length gauge.
2 Main features Inductive counting overcomes the shortcomings of mechanical length gauges that are prone to wear, high failure rates, difficult to repair, and inaccurate metering.
JSL-I electronic length gauge has length setting, number setting, length display, horse number display, total length display, length manual reset, number of manual reset, manual ink mark, full automatic ink Printing, full-axis parking and other functions can meet the requirements of the sizing process and equipment automation control.
JSL-type electronic length gauge has the function of barrel length setting, full-cylinder stop JSL-1 type electronic length gauge principle block diagram JSL-type electronic length gauge principle block car, which improves the automation degree of equipment. The fixed length of different varieties can be completed only by the electronic meter length switch setting, and the operation is very convenient.
The JSL-type electronic length gauge is applied to different devices. The user only needs to calculate the frequency division coefficient (the frequency division coefficient = the length unit D is the diameter of the roller on which the pulse is collected), and the frequency dividing circuit is set to satisfy the gauge length and The need for automatic control. Therefore, the JSL-type electronic length gauge has a multi-purpose function, that is, as long as the frequency division coefficient is changed, the same length gauge can be used for both the length of the combing device and the length of the device such as the draw frame and the roving.
It has a power-down protection circuit, so the data in the electronic length meter will not be automatically lost when the power is suddenly lost.
The JSL series electronic length gauge uses a large amount of component parameters, reliable quality and stable performance. The display part adopts high-brightness digital tube, which is clear and intuitive.
3 Applications in the textile industry JSL series electronic length gauges have a very wide range of applications. It can be used to control the in-process length of any non-reversing equipment and record production. The JSL-I electronic length gauge can meet the various process requirements of the sizing process and is widely used in various imported sizing machines and domestic sizing machines.
JSL-type electronic length gauge can be used for cleaning machine, carding machine, draw frame, combing machine, carding machine, roving machine, spinning frame, shaker, twisting machine, code cloth machine, etc. Automatic counting of products in other industries.
The parameter configuration for different process equipment used in the textile industry is shown in Table 1. JSL type gauge is used for parameter configuration of different equipment. Length of power transformer crossover remark unit/m primary voltage / V factor remarks draw frame comber roving machine The spinning frame 127 does not need to be fully loaded and the shaker is turned 220. Dividing factor 19 User-set code cloth machine code winding machine to Shaanxi cotton eleven factory preparation workshop sizing process using the G142 sizing machine produced in the early 1980s, these devices are all mechanical length counting device, precision It is low, and after more than ten years of use, it is mostly damaged and cannot be repaired. We use the JSL-I electronic length gauge on these devices to improve the accuracy of the gauge length, and the display is intuitive, the failure rate is low, the equipment operation rate is effectively improved, and the economic benefit is improved.
Due to the need of technical reform, a Zucker sizing machine in the spray-weaving workshop was relocated to the preparation workshop. This equipment has been damaged for many years and has not been used for a long time. Now it's time to restore the original functionality of the device so that it works well. If you purchase a new original meter, it will cost about 20,000 yuan. For this reason, we also use the JSL-I electronic length gauge on the equipment, which fully meets the control requirements and process requirements of the equipment, so that the equipment can operate normally, and Performance has been stable since recovery and has not failed.
The mechanical metering device used in the combing machine of the 11th factory in Shaanxi Cotton has been damaged for many years and can not be used normally. It can only be artificially estimated. That is, each car runs for about half an hour. The value of the sliver in the car is lower than the length of the sliver. The difference is large, so the length difference of the slivers in each cylinder is large, which affects the normal production of the next process; and the value of the lathe is labor intensive, and the number of machines that can be managed by per capita is small; the number of labors is large, and the labor productivity is low. We installed the JSL-type electronic length gauge on the equipment to realize the automatic control of the equipment. The length of each sliver was set in advance. After the equipment was full, the vehicle was automatically shut down and the signal was used to indicate the value of the lathe operation. In this way, the lengths of the cotton stalks of the same variety are very close, which ensures the normal production of the subsequent processes, and reduces the labor intensity of the value workers. The number of machines per capita is significantly increased, the labor of the process is reduced by nearly half, and the labor productivity is obviously improved.
The northwestern cotton four plant draw-up process was carried out in the early 1990s. All of them used the FA302 high-speed draw frame produced by Shenyang Textile Machinery Factory. The machine was originally equipped with the YH411A mechanical gauge device produced by Changzhou Textile Instrument Factory. The structure is complicated and expensive (1700 yuan per unit), the fault is difficult to repair, and the accessories are very expensive. To this end, we use the JSL-type electronic length gauge to replace the original gauge length device. JSL-type electronic length gauges are cheap, each price is less than the fraction of the original metering device, which greatly reduces the cost; can meet the requirements of process management, long-term use, and reliable quality.
The code cloth machine used in the finishing workshop of the Fourth National Cotton Factory in Northwest China adopts the method of equipment code and manual digital counting. This is time-consuming and laborious, the labor intensity is high, the production efficiency is low, and the meter length is inaccurate. The error rate is very high, and it is often criticized and punished by the factory. By adding a JSL-type electronic length gauge to the device, the automation of the code cloth machine is greatly improved, and the code cloth machine can automatically complete the code cloth and the metering work.
Whenever you start the code, just press the meter count reset switch to make the meter display zero and then start the device. After the code cloth machine is installed with the meter length meter, the effect is very satisfactory, the code cloth length accuracy is high, and the error code rate is almost zero. Code worker operation is easy and simple, which reduces labor intensity and significantly improves production efficiency. Before the change, the two people can only look after one car because of manual counting. After the improvement, the two can take care of multiple code cloth machines at the same time, and the effect is reduced.
The shaker of Xianyang Jianqin Line Factory originally used mechanical fixed length device. Every time you change one type, you must replace the fixed length gear. You must have multiple gears on the daily basis, which is time-consuming, labor-intensive and cost-effective. However, with the user's requirements Variety changes, still can not meet the requirements. We also installed the JSL-type electronic length gauge on this equipment, so that each time you change a variety, you only need to set the length through the meter in advance. After the full twist, the equipment will stop automatically, which is very convenient to operate, saves time and effort, and has value. The output of the lathe is cumulative. Now any length of product can be processed, eliminating the troubles of managers.
4 Conclusions, more parking and changing. In this way, since each car is burned due to broken bars, the printingJSL series electric meter is used in many factories and equipments, and the performance is stable, the quality is reliable, and the failure rate is low. Using JSL labor intensity, the production efficiency is improved, and the economic benefits are very obvious.
