Sole Edge Roughing Machine

This machine comes with an integrated all-in-one dust collection system. It can instantly suck up dust generated during grinding operations, drastically reducing dust dispersion and contamination in workshops and optimizing the on-site production environment.

The equipment is fitted with a pure copper core power motor that delivers powerful output and stable, long-lasting operation, fully adapting to uninterrupted mass production in shoe factories. The grinding wheel adopts a quick-disassembly structure, enabling simple and fast replacement of abrasive wheels with different grit sizes, flexibly accommodating various sole materials and different surface roughness requirements. The machine body is equipped with an angle-adjustable LED work light, providing bright and sufficient illumination for fine processing of tiny sole edge corners. A closed dust storage drawer is matched to collect dust centrally for easy unified cleaning without secondary dust scattering during waste disposal.

The whole machine frame is integrally fabricated from thickened steel plates, featuring a stable structure with extremely low vibration during grinding. It produces uniform and consistent grinding textures to guarantee stable precision of sole roughing processing. The machine adopts a simple button control layout equipped with an emergency stop button. Its intuitive operation logic allows workers to operate independently after short basic training. It boasts wide processing compatibility and can grind mainstream sole materials on the market including rubber, PU, EVA and TPR.

Soles roughened by this machine will form regular and uniform rough textures on the surface, expanding the contact area for adhesive bonding and greatly enhancing sole bonding strength, fundamentally lowering the defective rate of finished shoe delamination. The machine features a compact and small overall structure with a small floor footprint, making it convenient to embed into assembly line layouts as well as for independent small workstations in shoe mold workshops. Standard consumable spare parts for the machine are highly universal and easy to procure, effectively cutting daily maintenance costs.

A dedicated safety protective structure is installed on the grinding operation zone to isolate the high-speed rotating grinding wheel, preventing accidental contact between operators’ limbs and rotating components and eliminating all potential operational safety hazards. This sole edge roughing machine is applicable to shoe forming workshops, professional sole processing factories, post-processing assembly lines for shoe materials and shoe repair shops. It is primarily used for edge roughing and grinding before sole bonding procedures. Grinding treatment improves sole surface roughness and reinforces adhesive bonding performance, widely supporting the processing of all footwear types including sports shoes, casual shoes, labor safety work shoes and leather shoes.

Two power specifications are optional for the equipment. The low-power model adapts to small-batch shoe repair processing in stores, while the high-power model meets large-scale assembly line mass production in factories. Relying on stable and uniform grinding cutting force and an integrated dust-proof dust collection structure, the machine ensures consistent and stable roughing quality for each batch of soles while maintaining a clean and tidy workshop production environment, fully satisfying two core production requirements of the shoemaking industry: reliable sole bonding firmness and workshop dust pollution control.

The equipment has standardized complete operating procedures. Before startup, operators need to check the fastening status of the grinding wheel, confirm proper installation of the dust drawer and verify normal connection of power cables. Replace grinding wheels of matching specifications according to the sole material to be processed. Start the machine and wait for the spindle speed to stabilize before commencing grinding work. Hold the sole and press it evenly against the grinding edge, moving the workpiece at a constant speed to ensure consistent roughness across the entire grinding area. After finishing all daily processing tasks, cut off the machine power supply, wait until the spindle stops rotating completely, then clean dust inside the dust drawer and residual debris on the workbench.

Regularly inspect the wear degree of grinding wheels during daily production. Replace new grinding wheels promptly when severely worn to stabilize grinding processing quality. The equipment is equipped with standardized periodic maintenance specifications. Daily maintenance includes emptying dust from the dust drawer, wiping the workbench and checking for loose or wobbling grinding wheels. Weekly maintenance involves cleaning accumulated dust at the motor heat dissipation air vents, inspecting the sealing condition of dust suction pipelines and injecting special lubricating grease into spindle bearings. Conduct a comprehensive monthly inspection of all wiring connection points, tighten all loose screws and check for aging or damage to power cords and control switches.

The main power supply must be cut off before carrying out any maintenance or repair work on the equipment. Wait until the high-speed spindle comes to a complete stop prior to operation. When replacing grinding wheels, select spare parts matching the machine specifications to guarantee balanced spindle rotation without shaking. The machine has a low operation threshold with simple buttons paired with emergency stop protection design, safe and easy to operate. The built-in integrated dust extraction system collects dust in real time to reduce dust emission and workshop pollution.

The whole machine features low energy consumption, long service life and easily replaceable universal consumable parts. While achieving stable sole roughing and reducing delamination defects, it creates a clean, dust-free green processing environment, effectively optimizing workshop environmental management and assisting shoe factories in realizing clean, low-consumption circular production.
