About carding machine

Types of carding machines

A carding machine is an essential piece of equipment in textile manufacturing designed to untangle, separate, and align cotton fibers and other natural and synthetic fibers. Industrial carding machines differ from their manual counterparts because they are designed to produce a high volume of carded fiber. Various types of carding machines are available.

The carding machine is the third step in the process of transforming cotton into yarn. Raw cotton bolls are first opened in a luting machine and then spread into a tuft in a ginning machine before being carded by the carding machine. Once the cotton has been carded, it is fed into the spinning machine, the final step in creating cotton yarn.

The carding setup is usually composed of diverse cylindrical and circular brushes. The brushes and cylinders rotate at different speeds. This difference in speed allows fibers to be disentangled and aligned into a web or a loose sheet of fiber called a fiber lap.

Carding machines can be divided into the following categories:

  • Roller and Brush Card: The roller and brush carding machine uses a set of rollers and brushes to disentangle and align the fibers. The rotating rollers move the fiber while the stationary brushes catch the fiber. Usually made from treated steel, these cards are durable, long-lasting, and able to process cotton and other fibers at high speeds.
  • Mini Card/Mini Card with Pelton Wheel:The mini carding machine is more compact than the roller and brush version. It is fit for use in smaller textile milling facilities. While it has the same basic functions as other carding machines, the mini card is able to deal with smaller amounts of raw materials. Production speed may also be slowed down in the case of the mini carding machine. These machines are ideal for companies that need to process smaller batches of raw cotton.
  • Web Formation Card:There are two types of web formation cards: the reciprocating and revolving card. They are commonly used when working with synthetic fiber and are considered a more economical option than other carding machines to process raw material.
  • Combining Card:The combining carding machine is a more advanced option that manufacturers may use to produce high-quality, extensively refined carded fiber. The combining carding machine comes with a high price point and is generally used for processing cotton of superior quality.
  • Semi-Automatic Carding Machine:This type of carding machine comes with a tuft collector. It collects processed fibers in tuft and is prepared for further processing by the fiber into the spinning machine.
  • Automatic Carding Machine:The automatic machine performs all tasks and operations efficiently without the need for any manual help. It collects the fiber in a lap form. With advanced technology and automation, the carding machine enhances productivity.
  • Beating Card:The beating carding machine works by beating the fiber with the help of a rotating flat metal plate. It is the only machine currently being used on a small scale to card wool.

Specification and Maintenance of Carding Machines

The carding machine's specifications can change depending on what it's designed to make and its size. But here are some typical features.

  • Production Capacity

    Production capacity is usually measured in kilograms per hour (kg/h). For example, the carding machine for cotton may work at 80 to 200 kg/h or 300 to 600 kg/h.

  • Carding area

    It is available in different sizes ranging from 0.3m2 to 9m2; larger carding areas are available for specific customization.

  • Power consumption

    When working at full capacity, some machines may consume around 5-15 kilowatts (kW) for heavy-duty with more speed.

  • Compressed air requirement

    This is required in carding machines to feed the fiber layer on cards, and it may be around 0.5-1.5 kilowatts (kW).

Machines will require routine and periodic maintenance for optimal operation, which is the same for all types of carding machines, including woolen carding machines. Some parts will need more frequent attention, such as daily inspections and lubrication, than others. Following a scheduled maintenance plan will reduce the downtime and repairs required. It will keep the machines running at higher productivity.

The carding machine's main parts that need maintenance are the rolls, wires, and settings. The following maintenance activities can keep the carding machine in top shape.

  • Daily cleaning - carding machines are usually filthy after work due to lints and other debris. Removing all lint and debris each day will reduce the chances of component wear from dirt and debris.
  • Wipe down and lubrication - wiping down all parts with lint-free and oily rags will keep the parts free of dirt and keep them cool when working. Lubricating moving parts will also reduce friction and avoid component wear.
  • Weekly thorough cleaning - a more in-depth part-focused cleaning should be done each week. This involves removing the drums and cleaning wires and brushes. The process may require disassembly and focus on the parts that deal with fiber.
  • Check adjustments - carding machines will need adjustments to improve output and the quality of the carded items. Instructions from the manufacturer's manual should be followed when doing routine maintenance and adjustments.
  • Spare parts replacement - some parts will need replacing now and then to improve performance. They include bearings, wires, brushes, and drive belts. These parts wear out due to friction and frequent operation.

Industrial scenarios for carding machines

The main application of a carding machine is to untangle and parallelize fibers. Therefore, it is primarily used in the textile industry. However, its use is not limited to that. Here are some other applications of carding machines in various industries.

  • Textile industry: In this industry, carding machines are used to process cotton, wool, synthetic, and blended fibers. After the fibers are carded, they are further processed into yarn using spinning machines.
  • Paper industry: In this industry, carding machines are used to process cellulose pulp into fiber. This is done to improve fiber distribution in the pulp. Carding machines help separate contaminations and textile fibers. Afterward, the pulp is used to produce high-quality paper.
