Can Making Machine

Ear welding machine is used to attach the ears or lugs onto container, also named as ear welder or spot welder. The spot welding machine weld the lugs preparing for the handle forming-attaching machine, which is used to bend the metal wire as bails with hook and plastic grips, then mount the bails onto the lugs, also name as bail placing machine. Now a day, the two station can be combined as one combine to replace the lug welder and wire handle forming machine, and the spot spray coating system inside the lugs is available.

Automatic feeding double head ear welder is applied widely in conical pails and paint cans. For this type of metal containers, they require to weld metal components named ears, lugs or rivets on the outside of container body for the metal or plastic handles or bails. Then this type of machine is also named as spot welder or lug welder. GR specially produces ear welding machine for tin containers. Our automatic lug welding machine can automatically feed the cans or pails, then the spot welding machine will index the weld seam, to ensure the metal lugs are welded in fixed position. Then the metal lugs, ears or rivets in two hoppers will be automatically conveyed to the two welding heads separately and concurrently. After the can components are welded into the can body, the handle forming bail placing machine can be combined with the automatic spot welder as one machine or independently.

The bail placing machine is used to form the metal wire handle and mount the handle onto the can body. It is widely applied in paint cans or conical pails. The decoiler feeds the metal wire to the bail forming and mounting machine, then the plastic grips are fed from the hopper, and the metal wire insert into the plastic grips, the tool of the handle placing machine cut the wire and form the hook, then feed the complete bail onto the lugs on both side of containers. The whole process is fully automatic, if your handle is plastic, the handle placing machine also can mount your plastic handle onto the rivets of paint cans. GR produces machine base on your requirement. No matter plastic handle or metal bail, we can solve the problem for you.

Combination ear welding bail placing spot coating machine is the great innovation created by GR. The general line containers or pails require to weld metal lugs, ears or rivets on the outside of can body or pail body. In conventional technology, the metal handles are made by manual, then mounted onto the hole of metal lugs manually, and coated by brush manually, this process is complex and low efficiency, the production cost is also high. In order to help our customers reduce cost and improve efficiency, we invent combination machine with three main function: automatic spot welding, automatic bail forming and placing, automatic spray coating inside the welding spot. The combination ear welder bail mounter spot coater machine is smart and compact, it combines the total function of automatic feeding double head lug welder, then automatically feed the metal wire or plastic handle, and form it as predetermined shape, like plastic grips feeding and inserting, hook forming, then automatically place the bail into the hole of lugs or rivets, and use the spray coating nozzle to coat the inside the welding spot.

The combined machine consists of

1 Welding system

The spot welding machine is used to weld the lugs on the both side of conical pails or paint cans, so the machine is also name ear welding machine or lug welding machine.

2 Hopper

The hopper is also named as vibrator, it is a funnel shape device to fill with welding lugs or ears and arrange it in sequence, then feed the lugs one by one onto the paint can body or conical pail body.

3 Wire decoiler

The wire decoiling machine is to load the coil of metal wire, and decoil it to feed the wire placing system

4 Bail placing system

For the paint cans or conical pails, they are attached two lug components and placed with bail, so the can or pail can be equipped with wire handle. The bail placing machine can bend the wire to form as handle shape, insert the plastic grip onto the wire, and bend the hook on both side of wire handle, then attach the wire handle onto the container body automatically.

5 Spray coating system

The inside welding position of lugs can be coated by the spot coating system, the coating layer can protect the inside welding spot well.

How does the ear handle combination machine work?

1 Preparation of lugs, wire and grips

The welded lugs, formed wire and inserted grips are put on the hopper and decoiler first, preparing for the feeding.

2 Positioning

The paint can or conical pail are fed and detected for positioning the welding seam, so the position of welding spot can keep consistence.

3 Spot welding

The conical pail or paint can are welded with two piece of lugs at the same time, then conveyed to the next station.

4 Handle forming and attaching

After the ear welding, the metal wire is formed and attached onto the container body.

5 Spot coating

After the spot welding and handle mounting, the spray nozzle will coat a layer on the welding point by spraying.

Advantages

1 Innovative and combination

The type of machine combined with ear welder wire handle mounter and spray coater is only available in GR, this is our innovation in can making industry.

2 Cost reduction

For the conventional technology, the spot welder, bail mounter and spray coater are executed by independent machine or manually, the production cost is very high. Our machine combined with spot welder wire former spray coater can solve the problem.

3 Efficiency improvement

Due to the automation and combination, the ear welder-wire moulder-wire attacher-spray coater combined machine can increase the production capacity and improve the efficiency.

Applications

The combination machine can be used for the production for round paint cans and conical pail that with the ears and handles
