The so-called "smile curve" refers to the value-added curve of R&D, production, and circulation in the industrial chain of the present world. In the "smile curve", one end is R&D and design, the other end is sales and service, and the middle is processing and production. Similarly, the "smile curve" is referred to by the shoe industry as the lifeline of corporate development. As we all know, with the increasingly fierce competition in the footwear industry, especially under the impact of new international rules, the disadvantages such as overcapacity, homogenous competition, and lack of scientific and technological content have been exposed and painstakingly learned. Many foreign shoe enterprises have undergone transformation and change. In recent years, Chinese shoe enterprises have actively explored domestic and foreign markets while striving to develop new products. They have constantly worked hard on technology research and development and brand operations, firmly occupying both ends of the “smile curve†and making themselves maintain a steady development trend. A few days ago, another good news came that the shoe company Aokang formally appealed to the EU Supreme Court against anti-dumping cases for leather shoes, which marked the dawn of the Chinese shoe industry at the top of the “smile curveâ€. Through investigations, it is found that the rise of China's footwear industry has shaken the monopoly position of EU countries. Some European countries have formed alliances to protect the domestic footwear industry from maintaining prices. They have launched various barriers that restrict China's footwear industry from entering the European market. This restriction has been nearly 15 years. For Chinese shoe companies, both the time and energy have caused a huge impact, even to an unbearable point. This time, O'Connell took the lead in initiating an appeal against the EU ruling. Apart from seeking justice, the biggest goal is to prove to the world that the technological content of Chinese shoes already has an international standard. It is worth mentioning that in recent years, with the successive introduction of new international standards, Chinese shoe companies have not only shown no fear, but also focused on building a "smile curve" castle. Intensified efforts were made in product research and development to lead the new trend of industry product replacement with strong scientific and technological strength and continuous technological innovation. It also optimizes the configuration and efficiency of shoemaking equipment, enhances independent innovation and design elements in the product, and establishes a steady growth of sales channels, including comprehensive planning of understanding of various types of retailers, wholesalers, and stores engaged in physical distribution. It has realized the expansion from a single channel advantage to a diversified channel. We all know that China has a wealth of resources, a sound industrial chain, a huge processing capacity, a sound sales and marketing, and so on. This all contributes to the sustainable development of the industry. The overall advantages still exist. One can imagine the current upgrading of the shoe industry. Not so difficult. Coupled with the broad prospects of the international market, the overall foreign economy has shown a good momentum, residents' purchasing power has begun to recover, and consumption upgrades have boosted the retail growth of the footwear industry. All this has also helped promote the export of the footwear industry. Draw a "smile curve" to become the goal pursued by Chinese shoe companies. Therefore, Chinese shoe companies should actively increase the added value of the brand and make the brand image high-profile in the international market. We have reason to believe that Chinese shoe companies can win the unanimous recognition of the international market by their tenacious transformation and set sail in the vast international market, and they are bound to get to the two sides of the “smile curveâ€. High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.

The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
