Automatic Edge Grinding Machine for Melamine Tableware with PLC Control and 1200

Designed for continuous post-molding tableware finishing with reference production capacity of 1,200–2,400 pieces per hour. Actual output depends on product size, shape, edge profile, grinding requirement, and machine configuration.

Equipped with PLC control system and touchscreen HMI for convenient operation. Processing parameters can be adjusted according to different tableware products including grinding speed, conveyor timing, contact pressure, and processing cycle.

Adjustable grinding mechanism designed for different tableware edge profiles including flat edges, curved rims, deep edges, irregular shapes, and complex profiles.

Automatically performs flash removal, burr removal, edge sanding, and edge smoothing to improve edge consistency before final inspection and packaging.

Maintains controlled contact between sanding components and tableware edge for uniform grinding, reduced over-grinding, consistent edge profile, and stable batch processing.

Fixtures can be matched to different product shapes and dimensions including round plates, square plates, deep bowls, serving trays, cups, spoons, and irregular tableware.

Includes industrial dust extraction connection that can be matched with industrial vacuum equipment, independent dust collector, or central dust collection system.

Normally installed after hydraulic compression molding. Typical production line: Automatic Weighing → High-Frequency Preheating → Hydraulic Press Molding → Automatic Edge Grinding → Inspection → Packaging.

Different tableware products require different positioning methods. Fixtures can be customized for round plates, square plates, oval plates, bowls, trays, cups, spoons, and irregular products. Customers can provide product samples, dimensions, drawings, or product photos for fixture evaluation.

The grinding system can be adjusted according to product diameter, rim depth, edge thickness, curvature, and required finish. This allows the equipment to process multiple product specifications.

Machine configuration can be evaluated according to daily output, product dimensions, number of product types, and working shifts. This helps match grinding capacity with the output of the customer's existing melamine presses.

Reference electrical options include 380V / 220V / 3-Phase. Electrical configuration can be adjusted according to local factory requirements. Please provide voltage, frequency, and phase before machine production.

The dust extraction interface can be connected with industrial vacuum, independent dust collector, or central factory dust collection. The appropriate configuration depends on production volume and workshop layout.

DONGXIN can provide equipment matching for weighing, preheating, hydraulic pressing, grinding, and mold production. This allows customers to configure a more complete melamine tableware production solution.

Suitable for round plates, square plates, dinner plates, restaurant plates, and decorative plates. The machine removes molding flash and smooths the outer edge after compression molding.

Suitable for rice bowls, soup bowls, salad bowls, deep bowls, and serving bowls. Adjustable grinding settings can be matched to curved and deeper edge profiles.

Suitable for food trays, hotel trays, children's trays, cafeteria trays, and serving trays. Fixtures can be configured according to tray dimensions and edge structure.

Suitable configurations can be developed for melamine cups, small cups, and restaurant cups. The actual fixture should be matched according to the product dimensions.

The machine can also be configured for suitable spoons, sauce dishes, small serving pieces, and small molded products.

Suitable for manufacturers producing hotel dinnerware, restaurant plates, catering bowls, and commercial serving ware. Automatic finishing helps maintain consistent edge processing across larger production batches.

In addition to melamine tableware, suitable configurations can process selected urea formaldehyde molded products, resin products, and related thermosetting components. The final configuration should be confirmed according to material and product structure.

1. Customer Requirement Confirmation: Confirm product shape, dimensions, edge structure, required capacity, and factory voltage
2. Mechanical Assembly: Prepare and assemble machine frame, grinding mechanism, sand belt system, fixtures, and transfer components
3. PLC & Electrical Installation: Install and configure PLC, touchscreen setup, electrical wiring, sensor connection, and parameter configuration
4. Grinding System Setup: Adjust grinding heads and fixtures according to target products including grinding position, contact pressure, grinding angle, and product positioning
5. Sample Trial Grinding: Evaluate flash removal, edge smoothness, grinding uniformity, and product positioning using customer products or representative samples
6. Parameter Optimization: Adjust grinding parameters according to actual tableware structure and required finishing result
7. Continuous Operation Test: Check mechanical stability, PLC response, grinding head operation, product transfer, and continuous processing through repeated operating cycles
8. Final Inspection & Packaging: Inspect machine before packing and shipment

• Mechanical Inspection: Check frame stability, grinding head position, fixture alignment, and moving components
• Electrical Inspection: Check PLC, touchscreen, sensors, electrical wiring, and control components
