EW220-D28 Checkweigher for Bags

  • Checkweigher, inline dynamic checkweigher with pneumatic pusher reject, multihead weigher packaging line weight inspection, automatic pouch over/underweight removal. (Compatible with various types and sizes of pouches)

  • Outfitted with thickened load-bearing rollers & dual-side guiding rails, the checkweigher centers bulk cartons perfectly to avoid hanging, warped edges and piled boxes, cushioning upstream height-difference impacts.

  • Checkweigher auto-ejects out-of-tolerance cartons by air blowing: underweight from omitted inner bags/leaflets/manuals or overweight from excess fillings/spare parts. Net weight testing spans 5g to 1200g.

Product description
DESCRIPTION

Packages pass the infeed conveyor to trigger photoelectric switch and fully drop onto independent weighing platform. Load cells convert weight into electric signals for comparison with preset upper/lower weight limits. (Qualified: direct conveying to next process; Over/under weight: automatic rejection.)

Fitted with 10” CN/EN touch HMI, stores over 100 product formulas for one-click parameter switching. (Note: Keep gaps between pouches; overlapping/linked bags cause false rejection.)


1. Infeed :Uniform feeding, photoelectric timing ensures separate feeding without stacked pouches.

2. Weighing :Goods rest wholly on suspended weighing deck; strain-gauge / EMC load cells output millivolt electrical signals via pressure deformation.

3. Weight Comparison :Actual weight vs preset tolerance: qualified pass, out-of-spec sends signal to reject assembly.

4. Auto Reject & Data Record :Controller drives air blow / pusher / flip-plate to remove rejects; system auto counts rejects and saves data reports.
