KDT Edge Banding Machine Spare Conveyor Belt Feeding Device Nanxing

Belts that stop gripping halt an edgebander faster than any other fault. Part 48336340 is the conveyor belt feeding device for KDT and NANXING edgebanders, supplied as 1 new assembly: a steel shaft, 2 chain sprockets, a bearing seat block and a knurled tension knob. Worn sprockets let panels drift and stall at the infeed; this unit puts belt tension back where the boards enter. It covers 3 machine brands and ships by DHL, FedEx or UPS. Quotation on request.

Every shop running an edgebander meets the same 3 failures once the belt drive wears. Panels drift out of line because the top and bottom conveyors no longer pull at the same speed. The operator answers by hand-feeding every board, and the glue line opens at the ends. Then one worn sprocket stops the line while a replacement crosses the ocean.

Part 48336340 is the feeding device that sits in the belt track at the infeed: the unit that carries the chain, takes up slack and holds belt tension while panels run past the glue pot. It arrives complete, so the steel shaft, 2 sprockets, bearing seat block and knurled adjuster are matched instead of being 4 separate guesses.

Fitment covers KDT and NANXING edgebanders, and the same device is listed for HOLD HUAHUA machines, so 1 part number covers the belt feed on 3 machine brands. The unit is assembled before dispatch, so it goes back into the track at the height it came out of.

Condition is new, material is steel, and dispatch runs through DHL, FedEx or UPS. Send the machine model and a photo of the worn unit; the quote is matched to that photo, not to a catalogue guess.

What decides whether a device ends the stoppage or starts a second one:

• Steel shaft, one turned piece — the chain load runs along the full shaft, so the sprockets sit on steel, not on a pressed sleeve that creeps after a few months.
• 2 chain sprockets on 1 shaft — the pair engages the belt chain on 2 sides of the track, so pull stays square instead of hooking one edge.
• 1-piece bearing seat block — holds shaft, sprockets and mounting lug as 1 rigid unit, so belt height does not shift when the bolts are tightened.
• Knurled tension knob — tension is set by hand from outside the track in 1 step, with no shims and no feeler gauge.
• Fits 3 machine brands — KDT, NANXING and HOLD HUAHUA edgebanders take the same device, so a mixed line keeps 1 part number on the shelf.
• Complete assembly of 5 parts — shaft, 2 sprockets, bearing seat and knob arrive together: 1 line item instead of 5 pieces chased one at a time.
• 1-minute wear check — rock the sprocket by hand; side play or a hooked tooth profile means the device is the fault, not the belt.
• New condition, 3 couriers — each unit ships new by DHL, FedEx or UPS, tracking number sent the day it leaves.

When the belt drive fails you have 2 options: wait for an original part, or keep hand-feeding boards and hoping the glue line holds. Neither is a plan.

• The line restarts the week the box lands. A complete device means 1 swap at the infeed, not 5 parts ordered in sequence while the machine sits idle between deliveries.
• Panels stop drifting. With the sprocket pair back on a steel shaft, top and bottom belts pull at the same rate again, so boards enter the glue pot square and the edge sits flush on both faces.
• Fewer re-cuts, less waste. A feeding device that grips properly removes the hand-feeding correction that causes short panels and rework on every shift.
• 1 part number for a mixed line. Shops running KDT next to NANXING or HOLD HUAHUA stock 1 device instead of 3, which cuts the capital tied up in shelf spares.
• Diagnosis before purchase. You can tell whether you need this device or a new belt with a 1-minute hand check, so the money goes to the part that actually wore.
• Fitted by your own maintenance team. No press, no special puller: the assembly goes into the existing track and bolts down, so the repair fits inside 1 shift instead of waiting for a service visit.

Rock the sprocket by hand with the belt slack. Side play, a hooked tooth or a sprocket that turns on its shaft means the feeding device is worn, not the belt; a belt that is stretched but sits tight on clean teeth points to the belt instead.

Yes, if your machine carries the belt feeding device at the infeed. The part is listed for KDT, NANXING and HOLD HUAHUA edgebanders, so send the machine model plus a photo of the old unit and the fit is confirmed against that photo before you pay.

Complete. 1 assembly includes the steel shaft, 2 sprockets, the bearing seat block and the knurled tension knob, so there is 1 line item on the order and no mismatch between old and new teeth.

Because the top and bottom belts stop pulling at the same rate. Once the sprocket teeth hook or the shaft develops play, one belt slips while the other keeps pulling, so panels walk out of line and the drive stalls at the infeed.

No. The device is assembled before dispatch and goes into the existing belt track, so it bolts down with hand tools and returns to the belt height it came out of.

Yes. Tension is set by hand on the knurled knob from outside the track, so the guard stays on and the adjustment takes 1 step instead of a shim change.

Steel — the shaft and the bearing seat block carry the chain load, which is why the device survives continuous shifts where a pressed sleeve would creep.

By DHL, FedEx or UPS, with the tracking number sent the day it leaves. For a quote, give the machine model, the quantity and a photo of the worn unit; price is quoted on request against that information.
