Company: Xinxiang City Hongda Vibration Equipment Co., Ltd.

Product Description: GZG Series Vibrating FeederModel DescriptionWorking PrincipleThe feeding process of the GZG series motor vibrating feeder is achieved by using a specially designed vibration motor to drive the feeding chute in a periodic linear reciprocating motion along an inclined direction. When the vertical component of the acceleration of the chute's vibration exceeds the gravitational acceleration, the material in the chute is thrown upward and moves forward in a parabolic trajectory. The throwing and falling are completed within 1/50 of a second. Due to the continuous excitation of the vibration motor, the chute vibrates continuously, and the material in the chute continuously jumps forward to achieve the feeding purpose.Application RangeThe GZG series motor vibrating feeder is widely used in industries such as mining, metallurgy, coal, thermal power, refractory materials, glass, building materials, electric power, chemical engineering, machinery, light industry, and food processing. It is suitable for uniformly and continuously feeding block, granular, and powdered materials from storage bins or hoppers to receiving devices. The motor vibrating feeder can be used to feed materials to belt conveyors, vibrating conveyors, bucket elevators, crushers, vibrating screens, pulverizers, and other equipment. It can also be used in processes such as automatic batching, quantitative packaging, and automatic control to achieve automated production lines.FeaturesThe GZG series vibrating feeder is a new type of third-generation feeding equipment. Compared with other feeding equipment, it has the following characteristics:(1) Small size, light weight, simple structure, easy installation, minimal maintenance, and low cost;(2) Utilizes the self-synchronization principle of specially designed vibration motors, enabling quick start-up, stable operation, and smooth stopping;(3) Materials move forward continuously in a parabolic jumping trajectory, resulting in minimal wear on the feeding chute;(4) High feeding accuracy due to the ability to instantly change and control the material flow;(5) This series of vibrating feeders is not suitable for explosion-proof applications.The GZG series vibrating feeder can be customized according to user requirements into:(1) General type (not indicated), which is open and used for general feeding without special requirements;(2) Sealed type (F), featuring a rectangular enclosed structure, suitable for feeding in dusty environments;(3) Tube type (G), with a tubular feeding chute, suitable for feeding fragile particles and materials with high pollution or volatility;(4) Speed control type (T), suitable for feeding in automatic batching applications.Technical ParametersCustom sizes are supported; non-standard models are produced according to customer requirements.Installation and Debugging1. Hang the front and rear hooks; after installation, ensure the feeder is horizontally level. The centerline of the upper interface hopper should align with the centerline of the feeder's inlet, and the feeder's outlet should align with the lower interface to ensure the entire feeder is in a free state;2. The connection between the vibration motor and the conveying chute must be secure;3. The feeder can be installed horizontally or at an angle ranging from 0 to -12 degrees;4. Before starting, check whether the angle between the adjustable eccentric block and the fixed eccentric block of the two vibration motors is consistent. If not, adjust them to be consistent and tighten the fastening bolts;5. Perform a trial start and observe whether the two vibration motors rotate in opposite directions. If not, swap any two phases of the wiring of one vibration motor;6. After starting, observe that the machine body should not exhibit lateral swinging. The motor current should meet the requirements, and the entire machine should operate without abnormal noise.DescriptionThe GZG series motor vibrating feeder can be customized according to user needs into:Bottom vibration type: The vibration motor is placed below the feeder;Top vibration type: The vibration motor is placed above the feeder;Speed control type: The vibration frequency of the motor can be steplessly adjusted from 0 to the rated frequency;Open type: The top of the feeder is open, more suitable for the bottom vibration type, as shown in the sample diagram;Sealed type: The entire feeder is sealed except for the inlet and outlet;Base type: For large (heavy-duty) feeders, a base structure is generally used.The product is non-standard and can be customized according to customer requirements.

Company: Shenzhen Langte Technology Co., Ltd.

Product Description: Shenzhen Langte Technology Co., Ltd. provides compatible dimmers and driver power supplies for 0-10V dimmable light tubes. The related products offer excellent performance and multiple functions. Below is a detailed introduction:Dimming Principle1: The 0-10V dimmable light tube controls brightness by adjusting a DC voltage ranging from 0 to 10 volts. The dimmer outputs a 0-10V control signal, which is received by the LED driver power supply. By altering the output current of the power supply, stepless dimming of the LED light brightness is achieved. Higher voltage results in greater output current and brighter light, while lower voltage dims the light.Dimmer Parameters2: Taking Langte Technology's 0-10V dimmer as an example, the input voltage supports AC220V±10% with a frequency of 50/60Hz. It features 4-8 independent output channels, allowing grouped control of light tubes. It outputs a 0-10V DC voltage signal with a dimming accuracy of ±1%. It supports multiple control methods, including manual knob adjustment, RS485 communication (via external modules), and panel button control. It is compatible with LED power supplies and luminaires that support the 0-10V dimming protocol.Driver Power Supply Parameters2: Langte's dimming power supply has an input voltage range of AC100-240V and a frequency of 50/60Hz, with a power factor (PF) greater than 0.95. The output voltage is typically DC24V (adjustable based on light tube specifications), with a maximum output current of 41.7A for a 1000W dimming power supply. The ripple coefficient is less than 50mV to ensure stable power supply. It supports 0-10V dimming with a dimming depth of 0.1%-100% and includes overload, short-circuit, and over-temperature protection. The conversion efficiency is above 90%.Compatibility Advantages5: Langte Technology's driver dimmer supports 0-10V dimming technology and offers strong compatibility. It is not only suitable for the company's T5 and other dimmable light tubes but also compatible with LED light tubes from other brands. Users can adjust light intensity according to specific needs to achieve ideal lighting effects, making it suitable for various spaces such as office areas and home interiors where light intensity control is required.Wiring Method2: Connect the AC input terminal of the dimming power supply to the 220V mains. Connect the 0-10V signal output terminal of the dimmer to the dimming signal interface of the dimming power supply. Connect the positive and negative terminals of each light tube in parallel to the DC output terminal of the dimming power supply. Simultaneously, connect the dimming signal wire of the light tube to the dimming signal output terminal of the power supply to form a signal loop, enabling the dimming function. more>
