Screw capping machine

Types of screw capping machines

The screw capping machine is used to apply screw caps to containers, generally made of plastic or metal, designed to provide a secure closure. Various types of capping machines are available. The choice of which is best will depend on the production line's speed and bottle cap type.

• Semi-automatic screw capping machines

  A platform, either pneumatic or Manual, is provided to insert the bottle into the machine. Then, using a manually operated tool or a foot pedal, the cap is applied to the bottle by the capping head. This type of machine may provide protection against over-torquing and is usually adjustable to accommodate various bottle sizes.

• Automatic screw capping machines

  These machines are integrated into a production line. Bottles are conveyed automatically, and capping heads fitted with clutches or torque control apply the screw caps. Conveyors are used to feed bottles to the capping station, and a capping head with closure parts is used to apply the cap. The machine applies the cap and removes the need for re-tooling between bottle sizes. The required torque is set, and the machine will over-torque and slip when the preset torque is reached. This is an excellent choice for high-speed production lines. The machine may have capping heads with interchangeable closure parts. These are ideal for use in production lines where efficiency is critical.

• Spindle screw capping machines

  This type of machine uses electronically controlled wheels with adjustable speed and applied torque. Handling various cap and bottle shapes, it's fast and ensures consistent capping.

  Applicable industries: widely used in chemical, food, beverage, and daily chemical industries.

• Pick and Place Capping Machines

  In this machine, the operator places the cap on the bottle or jar. A vacuum system or gripper assembly is used to pick and place the cap correctly. The Torque motor capping head is then used to apply the cap with the desired torque.

Specification and Maintenance

• Machine Capacity:

  Screw capping machines are available in different capacities. The capacity is the number of caps the machine will put on bottles in a specific time. For example, a simple machine might cap 30 to 50 bottles per hour, while more complex ones could cap over 100 bottles in the same time.

• Cap Sizes:

  These machines can handle different cap sizes. Some models are made for small caps, while others work with big ones. A typical screw capping machine can fit caps with diameters ranging from 20mm to 110mm.

• Bottle Types:

  Screw capping machines are made to suit various bottle shapes. Some are made for round bottles, while others work with square or flat bottles. Also, some machines can handle bottles with different materials like glass, plastic, and metal.

• Power Usage:

  The power a screw capping machine consumes is given in watts or kilowatts. A simple machine might use 200 to 400 watts, while more sophisticated models could use 500 watts or more. The power determines how strong the machine is and its ability to cap bottles quickly and effectively.

• Machine Dimensions:

  This shows how big the machine is. Whether it's a table-top or stand-alone unit, the height, width, and depth will tell you how much space it will take up in your production area.

• Control System:

  Modern screw capping machines have control systems that let users set the capping torque, speed, and other important parameters. Some machines have a digital screen that shows the status of the machine, while others have buttons or switches to control it.

A screw water bottle capper machine is a valuable investment in the production line, so it is crucial to ensure it is well maintained so that it can operate efficiently and effectively and for a long time. The following are a few maintenance tips for a screw capping machine:

• It is important to regularly clean the capping machine thoroughly to remove any residue, dust, and dirt. This will help prevent any buildup that can affect the machine's operation and performance.
• Users should periodically lubricate all moving parts of the capping machine as recommended by the manufacturer. Doing this will help reduce friction, prevent premature wear, and ensure smooth operation and performance.
• Operation of the capping machine should be monitored to ensure it is performing optimally. This involves checking for any signs of abnormal wear, noise, vibration, or deviation. Any issues should be addressed promptly to avoid any downtime or interruptions in production.
• Users should stick to the recommended maintenance schedule by the manufacturer. This includes tasks like cleaning, lubricating, calibrating, and replacing parts as required. Adhering to the maintenance schedule will help improve the lifespan of the capping machine.
