. Operation mode
Touch screen operation The screen operation mode is divided into debugging and automatic working modes.
Debug mode In this mode, each switch of the main cylinder lifting, exhaust, charging, and pump speed adjustment is independent, and you can test whether it is operating normally or not.
In automatic mode, in this mode, the lifting, exhausting and charging of the main cylinder are controlled in correlation with each other.
. Other technical requirements
Use progressive heating and melting. The heating plate is located above the glue. When the heating plate is heated, only the upper layer of the glue barrel is in contact with the heating plate and reaches the melting point and melts. The lower part is insoluble at this time and meets the requirement of melting as much as needed for production.
Make sure the colloid is isolated from the air when dissolving.
The outer surface of the heating plate is coated with Teflon to prevent carbonization, ensure the best gelatin, and reduce clogging.
The inner tank is made of imported Teflon tube, which has good flexibility, good bending performance (maximum bending radius), anti-sticking and high temperature resistance (maximum accessibility), which can greatly reduce carbonization.
Using high-quality thermal insulation materials to ensure the thermal insulation performance of the throat and good thermal insulation effect.
The precision gear pump operation control motor adopts a stepless frequency converter for variable speed regulation. The glue amount and speed can be automatically tracked synchronously or controlled manually, which can accurately control the glue output.
When the temperature of the heating plate does not reach the temperature of the temperature controller, the main motor cannot run, which solves the problem of operator misoperation.
A sensor is installed under the main cylinder, which has the function of detecting the position of the heating plate, and has sound, light and control functions.
Active air opening and air closing design, the glue cutting response speed is sensitive and reliable.
The heater uses American heating wire and high-temperature-resistant wire, which is evenly wrapped around the outer wall of the throat. It has good insulation, uniform heat conduction, and high-temperature resistance. The built-in carbon fiber heating wire has excellent uniform heating performance and durability. sex.
The circuits between each throat spray gun adopt high-quality aviation quick plug-ins to ensure stable operation of the machine.
The conventional coating machine is equipped with a rubber hose of about one meter, with an inner diameter of Ф. The specific length is customized according to Party A’s needs. Each rubber transmission channel applies German high-efficiency sealing technology, and the sealing ring adopts the American Nordson brand, and ensures that the hose has good Thermal insulation performance and thermal insulation effect.
Germany’s latest sealed structural components ensure stable operation and long-lasting durability of the gun body.
Able to carry out intermittent and continuous glue spraying work at medium to low or high speed.
The return valve regulates the glue discharging pressure system. The glue gun stops working to ensure the safety of use. The high-density filter screen effectively filters impurities and prevents Clogging reduces maintenance downtime.
The materials used in the equipment must meet national industry standards
The overall requirements of the equipment are beautiful, environmentally friendly, safe, sturdy, high-precision, and reliable in control. The metal corners and edges of the equipment must be deburred to ensure a smooth and smooth feel. Stab the oarsman.
Each operation panel and operation key of the equipment must have an operation sign, indicating the purpose (function), and ensure that it is beautiful, does not fade, is clearly marked, is fixed reliably, and is in the correct position, so that it can be used for a long time without falling off or fading.
() All electrical components of the equipment comply with domestic electrical safety certification, and the entire equipment meets energy-saving certification requirements.
The design and installation of electrical circuits must comply with the "Low Voltage Distribution Devices and Circuit Design Specifications" and "Electrical Device Installation Engineering Construction and Acceptance Standards". The design of the electrical control system should consider the necessary circuit connections between each subsystem. Lock function, the entire system is well grounded, the electrical insulation performance reaches grade 1, the grounding impedance is well marked.
Each electrical control box of the equipment should be moisture-proof, anti-corrosion and mildew-proof. They should have good heat dissipation and be equipped with lighting.
The corresponding position of the equipment should be equipped with high-voltage hazards (strong electric hazards), be careful of collisions, and high-temperature hazards, and the installation should be tight, reliable, eye-catching, and intuitive.
Equipment safety protection devices need to be considered in dangerous areas of equipment to ensure the safety of employees.
The equipment and materials must be safe for operators to operate without any hazards and dangers, and comply with national safety, fire protection, environmental protection, health and epidemic prevention, and ergonomics requirements.
The equipment is not limited to the use of high initial strength polyurethane hot melt adhesive.
The hot melt adhesive used in supporting Party B's equipment must be resistant to aging, good temperature resistance, surfactant resistance, weak acid and weak alkali resistance, short-term resistance to fuel/solvent/oil, and alcohol solution/steam resistance after curing. , avoid contact with alcohol solution/steam during the sizing and curing process. Hot melt adhesive must be suitable for bonding to a variety of substrates, have good adhesion, and comply with quality assurance system certification and relevant safety protection regulations.
