Pouch Cell Edge Cutting Machine

Pouch Cell Edge Cutting Machine

Product Overview and Ideal Applications

The TOB-P-QB30 is a manual edge cutting machine for lithium polymer batteries. Its main application is pouch edge trimming before edge folding: the pouch edge is trimmed to a controlled margin before the folding step, so the edge presented to the folding process is clean and at the set width.

The same machine can also be used for aluminum laminated film pouch trimming after the pouch forming process. This covers the earlier trimming position of pouch cell work, where the formed aluminum laminated film pouch is trimmed before it continues along the assembly flow - so the machine serves two trimming points in pouch cell processing: trimming after pouch forming, and trimming before edge folding.

The TOB-P-QB system manual cutting machine has an adjustable cutting width for 2-8 mm, with cutting length 200 mm, 300 mm, or customized requirement. It is mainly used for lithium polymer battery research and production line. In the TOB-P-QB30 configuration, the edge cutting length is 300 mm and the margin width is 2.5-8 mm.

The utility supply is standard for a laboratory or a production floor: the machine runs on AC 110 V / 220 V, 50/60 Hz with a power of 500 W, and it requires an air supply of 0.6-0.8 MPa. The machine weighs 40 kg, and it is supplied with a one-year limited warranty with lifetime support.

Ideal for:

• Pouch cell production lines and battery research laboratories that trim the pouch edge before edge folding.
• Pouch forming processes that require aluminum laminated film pouch trimming after the pouch is formed.
• Cell formats that require an adjustable cutting width - 2.5-8 mm margin width on the TOB-P-QB30 - with a 300 mm edge cutting length.
• Trimming tasks where the cutting length is specified as 200 mm, 300 mm, or a customized requirement.
• Workshops and laboratories that provide AC 110 V / 220 V power and a compressed air supply of 0.6-0.8 MPa.

Where Edge Cutting Fits in the Pouch Cell Assembly Flow

In pouch cell assembly, the aluminum laminated film is formed into the cell case, and the pouch edges then pass through trimming (edge cutting), folding, and ironing (hotting) steps that give the finished cell a clean appearance and reduce the risk of damage from the sharp cut edge. Edge cutting sits directly before edge folding: the material that protrudes beyond the final fold is removed to a controlled margin, so that when the edge is folded and pressed, the fold runs on a consistent edge width.

The TOB-P-QB30 serves the trimming positions of this flow in two ways:

1. Pouch edge trimming before edge folding - the main application, in lithium polymer battery research and production.
2. Aluminum laminated film pouch trimming after the pouch forming process - trimming the formed pouch before it continues along the assembly flow.

Because the machine is a manual cutting machine, the operator presents each pouch and controls the cut of the edge to the set margin width. The adjustable cutting width lets one machine cover a range of pouch formats, and the 300 mm edge cutting length of the TOB-P-QB30 - with 200 mm, 300 mm, or customized lengths available in the series - covers common pouch edge dimensions.

How the TOB-P-QB30 Works

The TOB-P-QB30 is a manual cutting machine of the TOB-P-QB system: the trimming operation is carried out by the operator, who presents each pouch to the machine and cuts the edge to the set margin width. The working sequence is:

1. Set the cutting width (margin width) within the adjustable range for the pouch format being processed. The TOB-P-QB30 specification table lists a margin width of 2.5-8 mm, and the TOB-P-QB system description states an adjustable cutting width for 2-8 mm; both figures are reproduced from the product specification.
2. Present the pouch - the pouch edge before edge folding, or the formed aluminum laminated film pouch, depending on the process point - and trim the edge along the cutting length. The TOB-P-QB30 edge cutting length is 300 mm; the series also provides 200 mm, 300 mm, or customized cutting lengths.
3. Connect the machine to the required supplies: an air supply of 0.6-0.8 MPa, and an electrical supply of AC 110 V / 220 V, 50/60 Hz (power 500 W).

The machine is mainly used for lithium polymer battery research and production line, so the same unit can support laboratory work, pilot builds, and line-side trimming. Where the exact cutting width or cutting length for a specific pouch has to be fixed, our engineers can confirm the value against the specification table and the series description before ordering.

Key Engineering Characteristics of the TOB-P-QB30

1. Edge Trimming Directly Before Edge Folding: The machine's main application is pouch edge trimming before edge folding. Trimming at this point removes the excess pouch material to the set margin, so the downstream folding step works on a clean edge at a controlled width.
2. Serves Two Points of the Pouch Flow: Besides pre-folding edge trimming, the machine can be used for aluminum laminated film pouch trimming after the pouch forming process - one machine covers two trimming positions in pouch cell work.
3. Adjustable Cutting Width (Margin Width 2.5-8 mm on the TOB-P-QB30): The cutting width is adjustable, so a range of pouch formats can be trimmed on the same machine. The TOB-P-QB30 specification table lists a margin width of 2.5-8 mm, while the TOB-P-QB system description states an adjustable cutting width for 2-8 mm.
4. 300 mm Edge Cutting Length: The TOB-P-QB30 trims edges up to a 300 mm cutting length; the TOB-P-QB series also offers cutting lengths of 200 mm, 300 mm, or a customized requirement.
5. Manual Cutting Machine for Research and Production: The machine is a manual cutting machine, mainly used for lithium polymer battery research and production line - suited to laboratory work, pilot builds, and line-side trimming with the operator controlling each cut.
6. Wide-Voltage Supply: The voltage supply is AC 110 V / 220 V, 50/60 Hz with a power of 500 W, so the machine can be used on different mains standards in laboratories and factories.
7. Standard Plant-Air Requirement (0.6-0.8 MPa): The machine requires an air supply of 0.6-0.8 MPa, within the range of common laboratory and production compressed-air systems.
8. Compact Format with Lifetime Support: The machine weighs 40 kg, and it is supplied with a one-year limited warranty with lifetime support.
