Introduction: In the current social context, the development of green production is the only way out for the gravure packaging gravure industry. Enterprises do a good job in VOCs governance, adhere to the green development, can be considered from the following aspects.
The gravure packaging gravure printing industry uses petroleum products as the main raw material and belongs to industries with high energy consumption. In the process of gravure printing and compound processing of flexible packaging, the exhaust gas containing organic solvent discharged from the gravure printing machine and the exhaust gas discharge system of the composite machine not only causes the waste of non-renewable resources, but also causes environmental pollution. At the same time, the volatilization of organic solvents during use can also cause indoor pollution and production safety issues. In the current social context, the development of green production is the only way out for the gravure packaging gravure industry. Enterprises do a good job in VOCs governance, adhere to the green development, can be considered from the following aspects.
Reduce losses
In the process of flexible packaging, the cost of raw and auxiliary materials, inks and adhesives accounts for almost 70% to 80% of the total cost of printed products, regardless of material, energy, or time waste (such as in the process of changing rolls and changing jobs. In the middle), it will have a negative impact on the production and operation of the company and increase the cost. Therefore, it is necessary to minimize these wastes in production so as to effectively reduce costs.
The loss of material caused by waste generated during commissioning and overprinting of gravure packaging gravure printing processes is the greatest. If fine adjustment operations and process steps are closely linked, a stable and predictable scrap value can be obtained. At present, domestic gravure printing equipment manufacturers have successfully adopted the latest technologies such as rapid pre-registering and high-precision tension control, resulting in the loss of gravure cutting equipment, equipment restart loss (already registered), replacement loss, and the resumption of the previous The stored order loss, deceleration loss, etc., reached a rather low level, and even surpassed the international advanced level in some aspects.
Reduces operating aid time
Gravure printing equipment with advanced technology in the country adopts a series of new technologies, which greatly shortens the time required for assisting operations. For example, the integrated version of the upper version and the integrated model of the ink can be integrated into the upper version, the version, and the ink, and can be used offline. Cleaning roller and ink tank; quick inking system can directly supply organic solvent from the solvent room into the ink tray, the supply volume is controlled by the ink viscosity controller; sleeve type pressure roller technology does not need tooling replacement, labor intensity is reduced, replacement time Significantly shortened; quick change scraper technology enables rapid replacement of scrapers; laser side-to-edge system, safety chuck quick clamping system for quick roll-up and down; fault display and alarm system to help maintenance personnel quickly diagnose and handle faults; history fault alarm The indicator system reduces the time for maintenance personnel to troubleshoot.
Reducing the amount of consumables through print layout
(1) Color registration marks, slitting marks, bag-making marks, dot signal bars, etc. should be as small as possible and reasonable in color so as to reduce the loss of the film or the paper.
(2) Reduce the use of spot color and spot color inks and replace them with primary colors or stacked colors as much as possible to save the use of plate and ink.
(3) Reduce the number of colors, optimize the layout, and reduce the printing area (overlap rate).
Improve efficiency and automation, reduce dependence on people
In recent years, with the improvement of the overall level of domestic machinery manufacturing, domestic gravure printing equipment has been continuously innovating and has achieved gratifying results. At present, the highest speed of the gravure printing press has reached 400 meters/minute, and the printing efficiency has been greatly improved. At the same time, the level of automation of high-speed gravure printing presses has also been continuously improved. The application of full-automatic roll-up and roll-up technology, automatic cutting technology and on-line detection devices to gravure printing equipment has reduced the dependence of equipment on operators and greatly improved the equipment. The production efficiency.

Bulk cement truck chassis
Can choose dongfeng chassis, chassis, fukuda chassis of liberation and steyr heavy vehicle chassis, jianghuai chassis.
Bulk cement tank car
Bulk cement tank car is mainly composed of cylinder, the top of tank for inlet, fluidized bed, discharge tube assembly, of intake pipe and other accessories.
At the top of tank is equipped with two or three mouth to feed
CLW GROUP TRUCK Bulk cement truck tracheal road system
Bulk cement truck front, air chamber after each set an air inlet pipe, can be realized respectively by ball valve at the same time open and separate control.
CLW GROUP TRUCK Bulk cement truck Working principle of the system are as follows: motivation from the car gearbox, through the transmission device drives the air compressor, the compressed air in the gas pipeline interior control, make the tank of powder material produces fluidization phenomenon. When the pressure is 0.196 Mpa, open the discharge butterfly valve, discharge.
CLW GROUP TRUCK Bulk cement truck Use manual bulk cement truck
1, don't overspeed driving bulk cement truck, overpressure, running speed and overpressure can severely damage the air compressor. This machine is the highest speed main technical parameters see table, work pressure is 0.2 MPa.
2, don't start or stop the air compressor, fast and slow growth or slow down, otherwise, the impact force will damage the compressor.
3, don't change the rotation direction of air compressor, otherwise, the oil pump is not oil can seriously damage the machine.
4, do not stop in front of the reduced pressure air compressor, otherwise, the powder material may go back into the cylinder, air compressor is serious damage.
5, need to check the oil before starting the standard. Oil oil level shall not be lower than the lower limit; Need to check whether the oil pump oil supply, without oil, it is necessary to stop the machine immediately to check, otherwise, oil shortage will seriously damage the air compressor.
6, to timely replacement lubricating oil. Phone use after 30 hours, discharge of oil in the crankcase, clean inside the crankcase and oil screen, and then an oil change. According to the above oil change once a year later.
7, to check, clean oil screen. Normal quarterly inspection, cleaning time, if the machine utilization rate is high, should check and clean once a month.
8, this machine is used for CD40 lubricating oil diesel oil. Ban on different type of lubricating oil to mix, or lubricating oil deterioration will affect the lubrication effect.
9, each working 30 hours to maintain, clean air filter. While rotating filter pressure is less than 0.6 MPa compressed air blowing from inside to outside. Maintenance after five times, please replace the new filter. It is forbidden to oil or water to clean the filter element.
