Spring Feeder

The spring feeder is mainly composed of a feed inlet, a discharge outlet, a spring, a PPR hose, a motor and a hopper. It is an efficient, energy-saving, low-noise and reliable automatic conveying machine for powder materials and granular materials, which is an ideal choice for industrial material handling.This spring feeder equipment features compact structure, elegant appearance, stable operation, simplified work process, labor saving, improved working conditions and easy operation. It is suitable for plastic processing, chemical industry, food industry, pharmaceutical industry and other industries, thus winning the recognition and preference of numerous manufacturers.

The spring feeder adopts a fully enclosed design, which prevents dust from escaping during operation, effectively protecting materials from contamination and safeguarding the working environment. This fully enclosed spring feeder is highly favored by manufacturers focusing on clean production.This spring feeder is easy to operate, reliable in performance, stable in long-term operation and has a long service life, reducing maintenance costs for enterprises in the long run.The material conveying pipeline of the spring feeder is made of high-quality stainless steel with internal and external polishing treatment, ensuring clean and smooth material conveying, which meets the hygiene requirements of food and pharmaceutical industries for material conveying equipment.The spring feeder can be equipped with a frequency conversion speed-regulating motor to control the feeding process uniformly and stably, adapting to different production speeds and material requirements of various production lines.

Working Principle:

This spring feeder adopts the screw conveying principle. It uses a steel wire spring to rotate and convey plastic powder from the storage box to the hopper of the plastic molding machine. When the hopper is full, the level sensor sends a full material signal to stop feeding. When the material level drops to a certain position, the level sensor sends a signal to resume feeding. This cycle repeats, thus realizing automatic feeding. This automatic feeding principle of the spring feeder greatly improves production efficiency.

Applicable Materials:

The spring feeder is suitable for conveying powdery, granular, spherical and other materials. It can be used in conjunction with other equipment to achieve automatic feeding, and has the characteristics of stable performance, labor saving, safety and reliability. Due to the different materials used for the pipes, the spring feeder has good flexibility and can be bent, making it suitable for different production layout requirements. This multi-material applicable spring feeder is widely used in various industrial production lines.

Performance Advantages:

• Advanced and efficient structure, easy operation and maintenance. Compared with vacuum feeders, this spring feeder avoids the trouble of frequent filter cleaning, improving the overall operation efficiency of the production line.
• Enclosed automation. The parts of the spring feeder that come into contact with materials are made of stainless steel. During the conveying process, the raw materials are completely free from contamination and no foreign substances are introduced, enabling fully enclosed automation in the production process, which meets the high standards of clean production in the food and pharmaceutical industries.
• Automatic feeding. The spring feeder can be used with extruders of various specifications, and the feeding cycle is controlled by a level sensor to realize automation, which is convenient for manufacturers to integrate into existing production lines.
• Various configuration materials. The feeding pipe of the spring feeder can be nylon pipe or stainless steel pipe, allowing purchasers to choose according to actual production needs and budget.

Precautions:

• The spring feeder should be started first, and then materials should be added to the hopper. It is particularly important to clean the materials in the hopper after production and add new materials when using it next time to avoid material cross-contamination.
• When starting feeding, the feeding speed should be gradually increased until it reaches the rated conveying capacity. The feeding should be uniform; otherwise, it is easy to cause material blockage in the conveying process and overload of the drive motor, leading to equipment damage. Production line engineers should pay close attention to this during operation.
• To meet the requirement of no-load startup, before stopping the spring feeder each time, stop adding materials and wait until all materials in the hopper are conveyed before stopping the equipment operation. This helps extend the service life of the spring feeder.
• It is necessary to ensure that the conveyed materials do not contain hard large pieces. Because large pieces of materials will cause the screw to jam and then damage the motor, increasing the maintenance cost of the spring feeder for enterprises.
• During the production and use process, it is necessary to frequently inspect all parts of the spring feeder to check whether the fastening parts of the equipment are loose. If any looseness is found, it should be tightened in a timely manner to ensure the normal operation of the equipment.
• Before starting the spring feeder each time, first check the screws between the spiral pipe and the connecting shaft to see if they are loose. If looseness is found, correct it immediately to prevent equipment failure during operation.
• Do not remove the cover when the spring feeder is in operation; otherwise, accidents may occur. Safety operation of the spring feeder is crucial for protecting the safety of workers and the normal progress of production.
• If any abnormal phenomenon is found during the operation of the spring feeder, it is necessary to check first; do not continue to operate the equipment when problems are found. Timely inspection and maintenance can avoid further damage to the spring feeder.
