Blade Holder / Frame for Industrial Dough Dividers

Product Specifications

Technical details and manufacturing context for Blade Holder / Frame

Definition

The blade holder/frame is a rigid structural component used in industrial dough divider machines to mount and stabilize the cutting blades. It ensures precise blade alignment and spacing, which is critical for consistent dough portioning. The holder provides a fixed mounting platform, transferring mechanical forces from the divider mechanism to the blades while preventing deflection or misalignment during cutting cycles. Constructed from stainless steel, it is designed for food manufacturing environments, with material grades and surface finishes specified to meet hygiene and durability requirements. Key parameters include material grade (304/316L per ASTM A240), surface finish (Ra 0.8–1.6 μm per ISO 4287), blade slot width (2.0–3.0 mm) and depth (8–12 mm), parallelism (±0.05 mm per ISO 1101), flatness (0.1 mm per ISO 1101), operating temperature range (-10 to 80°C), maximum cutting force (5000–8000 N), weight (2.5–4.0 kg), and overall dimensions (300×150×40 mm). These values are reference ranges that must be verified for the specific model and application. The holder is available in 304 or 316L stainless steel; 316L is recommended for corrosive washdown environments. The surface finish can be specified to reduce bacterial adhesion. The blade slot dimensions must match the blade thickness tolerance to ensure secure seating. Parallelism and flatness tolerances are critical for uniform dough cutting and preventing blade distortion. Operating temperature and maximum cutting force limits must not be exceeded to avoid material creep or frame deformation. The weight and dimensions affect handling and installation, and can be customized per divider model. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The blade holder/frame operates as a rigid mounting platform. It holds the cutting blades in a fixed position relative to the dough surface, maintaining precise alignment and spacing. During the cutting cycle, the holder transfers mechanical forces from the divider mechanism to the blades, ensuring they cut through the dough consistently. The holder's structural rigidity prevents blade deflection or misalignment, which is essential for uniform portioning. The design must accommodate the blade dimensions and tolerate the applied forces without permanent deformation. The holder's flatness and parallelism are critical to ensure even cutting across the entire blade assembly. The material and surface finish are selected to withstand food manufacturing conditions, including washdowns and temperature variations.

Frequently Asked Questions

What materials are available for the blade holder/frame?

The blade holder/frame is available in stainless steel grades 304 or 316L, as specified in the source data. Grade 316L is recommended for corrosive washdown environments. The material grade should be verified with the manufacturer for the specific application.

What are the critical dimensions for blade slots?

The blade slot width is 2.0–3.0 mm and depth is 8–12 mm, as reference ranges. These must match the blade thickness tolerance to ensure secure seating. Confirm exact dimensions with the manufacturer for your blade specifications.

What are the operating temperature limits?

The operating temperature range is -10 to 80°C. Exceeding 80°C may cause material creep, which could affect the holder's performance. Always operate within this range and verify with the manufacturer for your specific conditions.

How is parallelism and flatness specified?

Parallelism is specified as ±0.05 mm and flatness as 0.1 mm, both per ISO 1101. These tolerances are critical for uniform dough cutting and preventing blade distortion. Verify these values with the manufacturer for your specific model.
