  The performance and advantages of cold glue system The main components of the  cold glue spray system : glue supply system device, intelligent glue spray controller, cold glue spray gun, cold glue conveying components have the characteristics of high efficiency, flexibility, good stability, easy maintenance, etc., are fast, high-quality production of various The necessary machines for paper boxes, folding sheets, document bags, and imitation bills are now widely welcomed by packaging manufacturers. The packaging production line has greatly improved production efficiency and saved glue costs. It can also support a variety of different Packaging production requirements, is the best partner for high-end folder gluers, folding machines, and corrugated box machines. The microprocessor controller is suitable for all kinds of high-speed production machines, because the multi-functional design of this controller relies on the programmable glue gun, which can achieve very ideal resul...

  The traditional method of   hot melt gluing system   is to mix high molecular weight polymers and low molecular weight gums to achieve the desired overall performance. At present, the biggest feature of the hot melt adhesive system is that the resin and polymer are based on petroleum raw materials. At present, the most widely used hot melt adhesive system is the ethylene-vinyl acetate copolymer (EVA) hot melt adhesive machine, which accounts for about 80% of the total output of the hot melt adhesive system. In addition to EVA, PE, PP, Polyester, polypeptide, PU, styrene and butadiene or isoprene block copolymers, ethylene-butene block copolymers, epoxy resins and phenolic resins, etc. Can be used for hot melt glue machine. Some new materials, such as EEA, EAA, EMA, PPO, PB, etc. are also used in hot melt glue machines. (1) Host polymer The polymer is the most important part of the hot melt glue machine. Some polymers can be used as hot melt glue machines without adding ...

  Vacuum plasma surface treatment features Features of Vacuum  plasma surface treatment 1. Large processing space, increase processing capacity, adopt PLC control system, and accurately control the operation of equipment. 2. Can be customized according to customer needs to meet customer needs. 3. Low maintenance cost, convenient for customer cost control. 4. High precision, fast response, good controllability and compatibility, perfect functions and professional technical support. Principle of vacuum plasma cleaning Plasma is a state of existence of matter. Generally, matter exists in three states: solid, liquid, and gas, but in some special cases, there is a fourth state, such as the substance in the ionosphere in the earth’s atmosphere. The following substances exist in the plasma state: electrons in a state of high-speed motion; neutral atoms, molecules, and groups of atoms (radicals) in an activated state; ionized atoms and molecules; unreacted molecules, atoms, etc., but ...

  Plasma, the fourth state of matter, is an ionized gaseous substance composed of atoms deprived of some electrons and positive and negative electrons generated after atoms are ionized. Its energy range is higher than that of gas, liquid, and solid matter. There are electrons, ions and neutral particles with a certain energy distribution. When they collide with the surface of the material, they will transfer their energy to the molecules and atoms on the surface of the material. A series of physical and chemical processes. Its function on the surface of the object can achieve ultra-clean cleaning of the object, surface activation, etching, finishing and plasma surface coating. (1) Etching on the surface of the material A large number of active particles in the plasma, such as a large number of ions, excited molecules, and free radicals, act on the surface of a solid sample to remove the original contamination The surface becomes rough, forming many tiny potholes, increasing the spe...

  Due to the low surface tension of most plastic materials, many designs in the past tended to adapt to the use of materials. Nowadays, as long as the surface can meet the requirements of spraying or bonding after a certain plasma surface treatment, it can be used first. This material. In recent years, cost and material use characteristics have become the dominant factors in product design, which has caused automakers to begin to focus on more plastic varieties. At present, PP, PC, ABS, SMC, various elastomers and various composite materials have been widely used in automobile manufacturing. In this case, it is necessary not only to deal with the mutual adhesion problem between the same material parts, but also to solve the mutual adhesion problem between different material parts. However, the past plasma surface treatment methods are obviously difficult to meet this processing process. Requirements. In terms of  plasma surface treatment  effect, among all the current sur...

  Application of cold glue spraying system in box gluing machine The  cold glue spray system  can help paste box application manufacturers to improve product quality and production efficiency. The glue spraying system replaces the traditional roller gluing process, and can spray different adhesives according to various application requirements, which can be used for linear gluing and overlocking, bottom locking, on 2 or 4 or 6 corners. Gluing, and bonding see-through skylights, etc. Using a high-speed electronic spray gun can greatly improve the accuracy of the cold glue spraying position Cold glue high-speed electronic spray gun can reach a glue speed of 500 points per second Piston pump can meet the demand of large amount of glue, while effectively protecting the characteristics of glue The cold glue system can accurately quantify glue, and there will be no dripping, tailing or flying wire phenomenon. The use of corrugated boxes The cold glue spray system is simple to o...

  Common problems in hot melt system work 1. The stigma is too small after melting (1) The temperature is too low The more obvious phenomenon is that everything is completed as required. When  hot melt system  after the fusion is over, it can be seen through observation that the column head is small, the components are relatively loose, and they can even be separated between them. If you look at the thermostat at this time, you can see from the top of the thermostat display that the actual temperature does not match the set temperature. The solution is: first check whether the thermocouple switch is turned on, otherwise, turn on the thermocouple switch first. The next thing to do is to wait for the actual temperature to reach the set temperature before it can be made into a hot melt. (2) The hot-melt head and the hot-melt column are not straight after the fusion is completed. From the structural parts, it can be seen that only part of the hot-melt is melted. From the appe...
