A collar type packing machine is a type of vertical form-fill-seal (VFFS) packaging machine commonly used in the packaging industry to efficiently form, fill, and seal flexible bags or pouches. Here's a description of a typical collar type packing machine:

1. Construction: The main components of a collar type packing machine include:

   • Frame: The machine frame provides support and stability for the various components and ensures proper alignment during operation.
   • Film Unwinding System: Rolls of flexible packaging film are mounted on a film unwinding system, which feeds the film into the machine for bag formation.
   • Forming Collar: The forming collar is a cylindrical tube or mandrel that shapes the film into a tube or sleeve as it passes through the machine.
   • Filling System: The filling system dispenses the product into the formed bags or pouches. Depending on the application, filling may be done using volumetric fillers, weighers, augers, or liquid pumps.
   • Sealing System: The sealing system consists of heated sealing bars or jaws that seal the edges of the film to form individual bags or pouches. Common sealing methods include heat sealing, impulse sealing, or ultrasonic sealing.
   • Cutting Mechanism: After sealing, the bags or pouches are cut from the continuous film roll using a cutting mechanism such as a rotary blade or heated wire.
   • Control Panel: The machine is equipped with a control panel that allows operators to adjust packaging parameters such as bag length, fill volume, sealing temperature, and speed. It may include digital displays, buttons, and knobs for user-friendly operation.

2. Operation: The operation of a collar type packing machine typically involves the following steps:

   • Film Feeding: The packaging film is unwound from the roll and fed into the machine, passing through the forming collar.
   • Bag Formation: The film is shaped into a tube or sleeve around the forming collar, creating a continuous tube of film.
   • Product Filling: The product is dispensed into the formed bags or pouches through the filling system.
   • Sealing: The edges of the film are sealed together to form individual bags or pouches using the sealing system.
   • Cutting: The sealed bags or pouches are cut from the continuous film roll using the cutting mechanism.
   • Discharge: The filled and sealed bags or pouches are discharged from the machine onto a conveyor belt or chute for further processing or packaging.

3. Features and Options: Collar type packing machines may include various features and options to enhance productivity and versatility, such as:

   • Multiple Filling Stations: Some machines are equipped with multiple filling stations to fill multiple bags or pouches simultaneously, increasing throughput.
   • Adjustable Bag Length: Operators can adjust the bag length to accommodate different product sizes and packaging requirements.
   • Gas Flushing System: Some machines may be equipped with a gas flushing system to displace oxygen inside the bags or pouches with inert gas, extending product shelf life.
   • Print Registration: Machines may include a print registration system to accurately align printed graphics or labels on the packaging film.

4. Applications: Collar type packing machines are used in various industries for packaging a wide range of products, including:

   • Food and Beverage: Snacks, confectionery, grains, nuts, frozen foods, coffee, tea, pet food.
   • Pharmaceuticals: Tablets, capsules, powders, granules, medical devices.
   • Household Products: Detergents, cleaning agents, personal care products.
   • Industrial Products: Chemicals, powders, granules, hardware components.
