COLD STORAGE DOOR

Introduction of soft curtain anti-collision fast door
The heat preservation and energy saving internal fast door in the fast cold chain logistics area helps to save energy, reduce air convection, and reduce noise.
The structure design of the soft curtain anti-collision fast door is concise, which is conducive to stable operation, reduces the frequency of maintenance and replacement of vulnerable parts, and effectively improves the durability and service life of the equipment. The curtain can derail in the event of an accidental impact, and during the ascent process Automatic reset, no need for manual repair and reset during the whole process. There are heating devices on both sides of the column. The structural design of this product is characterized by more than 150,000 trouble-free operations per year. It has the characteristics of the highest practicability and the lowest maintenance cost. The design of the fast cold storage door with soft curtain is simple, and the heating and antifreeze device is designed to ensure the smooth and effective operation of the product in the low temperature working environment. The structure incorporates the functional design of anti-collision recovery. When the door is accidentally hit, it will leave the track and automatically repair and return during the ascent process. This structure is not only conducive to the safe and stable operation of the door, but also runs more than 150,000 times without failures per year. , It prolongs the service life of the product, and reduces the cost of component replacement and maintenance.

Curtain
High-strength environmentally friendly polyester fiber material is added with anti-tear fabric, blue, the overall thickness of the full-soft curtain is not less than 1mm, the tensile strength is high, the durability is good, the friction between the curtains will not generate static electricity to absorb dust, the middle of the curtain Fill with insulation material. Applicable temperature: -30~+70℃. The track is made of stainless steel and galvanized paint, and the surface is sprayed with plastic, so it will not rust.

Drive System
Professional industrial door HOFIC motor system consists of: fast door special high-speed motor, power supply 220V, power 0.75kw/750 rpm/S, load-bearing S4 type. Power failure brake system; reducer; manual release mechanism; faulty manual device, etc.,
Motor constant torque output:
1. Strong overload capacity, it can work more than 2000 times a day in some high frequency occasions.
2. The 2000-line high-resolution encoder and the fast response characteristics of the motor effectively avoid the problem of accumulated errors.
3. The manual release mechanism can be released in case of failure or power failure, and the door can be opened or closed manually in an ideal position.

Control System
Using a dedicated (HOFIC) servo system, the core is a DSP chip, the system sets the opening height of the door by receiving the incremental encoder signal from the tail of the motor and the mechanical origin position switch signal:
1. The system has the function of displaying the fault code through the LED tube;
2. Steering protection: When the motor drive line is connected wrongly, the controller will report an error directly, and the door will not move;
3. The three loops of the torsion loop, position loop and speed loop are fully closed;
4. Energy brake function, which can stop the motor at the expected position without using electromagnetic brake pads, so that when the door stops at the limit position, it is not bad at all;

Anti-collision recovery structure
In the event of an accidental impact, the door curtain can be derailed and automatically reset during the ascent. The whole process does not require manual repair and resetting of the control unit.

Heating antifreeze device
The design and application of the heating mechanism avoid the freezing of the guide rail caused by the heat exchange caused by the frequent operation of the door, and further ensure the stable operation and working efficiency of the door in a low temperature environment. At the same time, the box removal equipment can be selected as needed to double guarantee the working performance of the product in a low temperature environment.
