Cloth feeding device of tentering setting machine for flame-retardant base cloth production

By using a motor-driven bidirectional lead screw and a moving block design with a limit mounting plate, combined with rotary wheels and rollers for transmission, the problem of the inability to adjust the limit structure in existing technologies is solved. This enables precise positioning and stable transmission of fabrics of different widths, improving production efficiency and product quality.

AI Technical Summary

Technical Problem

The existing flame-retardant base fabric production stenter has a fixed design for the fabric feeding device limit structure, which cannot be flexibly adjusted according to actual production needs. This leads to misalignment, wrinkling, and slippage of the base fabric when the width is not suitable, affecting the feeding efficiency and product quality.

Method used

The system uses a motor-driven bidirectional lead screw to move the moving block and the limiting mounting plate laterally. Combined with the conveyor wheels and rollers, the fabric is conveyed, and the idler rollers support the fabric to reduce friction, thus achieving adaptive positioning and stable conveying of fabrics of different widths.

Benefits of technology

It improves fabric loading efficiency, prevents fabric shifting and wrinkles, keeps the fabric surface flat, and enhances production efficiency and product appearance quality.

Abstract

The utility model relates to a cloth feeding device of a tentering setting machine for flame-retardant base cloth production, and relates to the technical field of cloth processing, the cloth feeding device comprises a bottom plate, a mounting seat is arranged above the bottom plate, the top surface of the mounting seat is connected with a mounting frame, one side of the mounting frame is connected with a first motor, and the first motor is connected with a second motor; the output end of the first motor is connected with a bidirectional screw rod, the outer wall of the bidirectional screw rod is in threaded connection with a moving block, the bottom surface of the moving block is connected with a connecting rod, the bottom surface of the connecting rod is connected with a fixed seat, and a limiting mounting plate is arranged in the fixed seat. When the cloth feeding device is used, the movable blocks on the two sides are driven to move face to face or back to back in the axial direction of the lead screw, then the fixing base and the limiting installation plate in the fixing base move transversely, the cloth feeding device can adapt to cloth of different widths, the situations that the cloth deviates, wrinkles, slips and the like due to the fact that the width of base cloth does not accord with the preset size of a limiting structure are avoided, and the cloth feeding efficiency is greatly improved.
