Q:Predecessors please point out: what is the future of packaging machinery industry?

Hello, in recent years, Chinese packaging industry, although the annual growth rate ranked in the traditional industry for the first time, but in line with the international market, to accelerate the development of packaging technology, make its development to the economic, efficient, multi-functional direction. According to the development plan of Chinese national economy and to realize well-off life level, this year a few years for the packaging industry, the food industry to provide equipment for 100 billion yuan to 200 billion yuan, 80 billion yuan to 100 billion yuan to provide equipment for the "vegetable basket", this is a good opportunity for development of enterprises. At the same time, I learned from the relevant ministries, "95" period, will invest 10 billion yuan in the packaging industry to support and transform large and medium-sized packaging enterprises.

Q:Color code positioning of packaging machinery

Color code positioning and photoelectric trackingIn order to ensure the integrity of the mark on the finished package, it is usually printed on the package for positioning.

Q:A & B two sets of packaging machines, at the same time packaging quality of 500 kilograms of goods

(3) large variance, indicating that this group of data volatility, variance is small, volatility is relatively stableAnswer: (1) a = x (501+500+503+506+504+506+500+498+497+495), 10=501,B = x (503+504+502+498+499+501+505+497+502+499), 10=501;(2) S2, =1/n[(501-501) 2+ (500-501) 2+... + (495-501) 2]=12.6,S2 B, =1/n[(503-501) 2+ (504-501) 2+... + (499-501) 2]=6.4;(3) a b > S2 dreams S2,The quality of R B packaging machine 10 bags of sweets is relatively stable.Comments on the subject, mainly on the average number, variance calculation, and their significance, the correct memory formula is the key to solving problems

Q:Bread packing machine Product features

4., high sensitivity photoelectric eye mark tracking, digital input seal cutting position, so that the seal cutting position more accurate.5. temperature independent PID control, better for all kinds of packaging materials.6. 、 positioning stop function, no sticking knife, no waste of coating.7. drive system is simple, more reliable work, more convenient maintenance.8. all control is realized by software, which is convenient for function adjustment and technical upgrading, and never falls behind.

Q:Energy saving reform of packaging machine

A) the main control circuit is composed of man-machine interface (text display), frequency converter and programmable logic controller (PLC), which constitute the control core;B) the temperature control circuit is composed of an intelligent temperature control meter, a solid state relay and a thermocouple element. The temperature control is accurate, the display is intuitive, and the setting is convenient;C) multi point tracking and detection by photoelectric switches and electromagnetic proximity sensors; 2) fully automatic pillow type working principle:With the improvement of automation, the operation, maintenance and routine maintenance of the packing machine are more convenient and simple, and the professional skill requirements of the operators are reduced. The quality of the product packaging is directly related to the temperature system, the speed accuracy of the main engine and the stability of the tracking system.

Q:Ask a mechanical problem, the waste film recycling in the packaging machinery is a new film packaging, after cutting, then use the roller to recycle the waste film. Encounter a

It is suggested that displacement or velocity should be detected on the transport path of the membrane. Is a more reliable control signal. Of course, you can also detect the angular speed of the recovery drum, such as a code dial and other simple institutions.
