Touch Screen Sponge Peeling Machine with 1-30 mm Thickness and 0-130 m/min Speed

The TDPA-2300 removes the gear set from sponge peeling. Sheet thickness from 1 mm to 30 mm is typed on the CNC touch screen, the peeling head runs at 0-130 m/min, and the machine holds ±0.08 mm on 1-3 mm sheet. It peels rolls and blocks from 20 mm to 1500 mm diameter and up to 3000 mm wide, on an 8.69 kW drive with a 2000 kg machine and a 5000*2500*2000 mm footprint.

This is the specification that matters to a plant running mixed orders. When each change of thickness needs a gear, a gauge block and a trial cut, small batches carry a setup cost that eats the margin. With the TDPA-2300 the change is a number on a screen, so a 200 sheet order of one size and a 50 sheet order of another can run in the same shift without a mechanical rebuild.

1. Finish the run. Peel the current roll out and take the last sheet off the table.
2. Enter the new thickness. Type the next value, 1 mm to 30 mm, on the touch screen.
3. Set the speed. Pick the peeling speed for the new foam grade within 0-130 m/min.
4. Chuck the new roll. Mount the roll, check run-out at the far end and confirm it is square.
5. Peel a test sheet. Measure the first metre at both edges and the centre against a gauge.
6. Run the batch. If the sample is in tolerance, run the order without touching the setting.

A changeover is one screen entry, one chucking step and one measured test sheet. That is the whole cost of moving between sizes, which is why a plant with mixed orders can hold short runs on one machine.

A mechanical peeling machine sets thickness through a gear or a gauge block. Every size change means a swap, a trial cut and usually a strip of scrap foam before the sheet is right. On a long run that cost disappears into the batch. On a 50 sheet order it is a visible share of the price.

The second cost is consistency. A gear set can be re-fitted slightly differently, so a repeat order can come back 0.1 mm off a previous batch even though nothing was changed on purpose. A numeric setting removes that variable: the value in the machine log is the value that ran.

The third cost is skill. A gear change is a task for an experienced fitter, which means the machine waits when that person is not on shift. A touch screen setting can be made by the operator who is already running the machine, and the batch does not queue behind a maintenance call.

• Short runs: a 1-3 mm comfort layer order and a 20-30 mm packaging order in the same shift without a fitter.
• Repeat orders: keep the setting in the batch log so the next order is run without a sample cycle.
• Trials: a new thickness is one entry and one test sheet instead of a setup rebuild.

• Changeover by number: 1 mm to 30 mm is set on the touch screen, which removes the gear swap and the scrap from the trial cut.
• Repeatable output: the recorded setting reproduces the same sheet on the next order, so a repeat buyer gets the same thickness without re-sampling.
• Thin sheet on demand: peeling down to 1 mm at 0-130 m/min covers comfort layer, packaging and lamination grades.
• Tolerance on thin sheet: ±0.08 mm on 1-3 mm keeps the sheet inside the band that buyers actually measure.
• One machine, many sizes: 20-1500 mm diameter and 500-3000 mm width means blocks, cylinders and long rolls run on the same head.
• Operator friendly: one screen for thickness, speed and start, so a new operator runs a batch in a single shift.
• Low failure rate: a rotary head without reciprocating shock load needs fewer interventions and fewer spare parts.

• Mixed-order foam conversion: several thicknesses for different customers in one shift.
• Packaging and protective foam: thin sheet in a range of sizes with short runs.
• Furniture and mattress: comfort layers and padding peeled to order.
• Footwear: insole and lining foam at fixed thicknesses.
• Lamination and composite: uniform thin foam for bonding lines.
• Sample and trial production: new thicknesses tested without a setup rebuild.

Most thickness complaints come from the first metre of a roll. Check that metre before running the rest of the batch, and one rejected sheet replaces half a shift of scrap.

The machine is controlled from one screen, so the operator has to be trained on the two things that matter: the thickness value and the roll condition. A correct setting on a roll that is not square still produces a wavy first metre, and the operator is the only person who can catch that before the batch runs.

Keep a batch log per order: foam grade, density, roll diameter, thickness setting, speed, blade hours and the measurement from the first sheet. When a repeat order comes in, the log reproduces the run instead of guessing at a setting that worked last month.

• Guarding: keep the head guard fitted and the emergency stop reachable from the take-off position.
• Setting: change the thickness only when the head is stopped and the roll is not turning.
• Dust: run extraction on dusting grades; foam dust in the guide is what opens a thin-sheet tolerance.
• Handling: use a roll cradle or a lift for large rolls instead of tipping them onto the chuck.

A machine with a numeric setting still depends on a sharp blade and a correctly set guide. Check the edge every shift, re-set the guide with a gauge after each blade change, and keep the touch screen and cabinet clear of foam dust so the setting you entered is the setting that runs.

The wear parts are the blade, the guide and the drive pulley, all of which are shipped as spares with the machine. Everything else is routine: lubrication, cabinet dust and a monthly thickness check against a gauge on a test roll.

• Every shift: blade edge, guide clearance, screen and cabinet dust.
• Weekly: blade tension, drive pulley, extraction filter, chuck condition.
• Monthly: lubrication, electrical check, thickness verification on a test roll.
• After a blade change: re-set the guide and run one measured test roll.

The machine is packed in an export plywood case with the head blocked, the screen protected and blades boxed separately. At 5000*2500*2000 mm and 2000 kg, confirm the container plan and the door width at the receiving site before booking freight.

Delivery is 45 working days after downpayment, payment by L/C or T/T, minimum order one set. Installation guidance and remote commissioning support are included, and spare blades, guides and belts can ship with the machine.
