Description

Automatic folding and cross-cutting machine for seamless fabric

Technical field:

The invention relates to an automatic folding and cross-cutting machine for non-woven fabrics, which is used for semi-finished cross-cutting machines for making non-woven fabrics to make environmental protection bags, shopping bags and other materials to make handbags.

Background technique:

Environmental protection bags and shopping bags have attracted more and more attention from modern people due to the strengthening of modern people's intentions for environmental protection. Since most of the manufacturing is done by hand-operated tools, the fabric is firstly multi-layered, and then the fabric is cut with an electric cutter. Cut it according to the specifications of the bag, then use a sewing machine or an ultrasonic sewing machine to sew the edge of the bag mouth, and finally fold the semi-finished product on both sides of the bag sewed in half, and then continue to sew to form a product. The various production tools of the sequence are expensive.

Invention content:

The technical problem solved by the present invention is to provide the principle of automatic machine movement to make the first few steps of making seamless cloth shopping bags or environmental protection bags, saving costs and improving production efficiency.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention to solve the technical problems is: provide a cloth conveying method to solve the hemming of the bag mouth, stitching and punching, and finally cutting the semi-finished product. Including frame, automatic folding mechanism, ultrasonic sewing mechanism, continuous dragging mechanism, interval feeding mechanism, automatic cutting mechanism and braking mechanism. The cloth conveying method is driven by the continuous dragging mechanism, drags the cloth through the automatic folding mechanism, folds the edges of the pockets on both sides, and then sends the cloth into the cloth storage rack after being stitched by the ultrasonic sewing mechanism. Then the intermittent feeding mechanism sends the cloth into the cutting mechanism with one movement and one stop for cutting work, combined with the electronic counter and material sensor of the braking mechanism, the automatic cutting effect is realized. The automatic folding mechanism is above the frame Set a hemming roller, the fabric passes through the hemming roller in a semicircular shape, and the hemming rollers on both sides will lose tension if they do not reach the position, and the fabric that has lost tension will be folded down through the hemming device below, and will be conveyed by the rolling of the rollers , Send the folded fabric between the welding head of the ultrasonic transducer and the embossing wheel to realize automatic sewing.

The continuous dragging mechanism is driven by the driving motor A through variable speed and simultaneously drives the rolling embossing wheel and 2 continuous dragging active wheels, combined with 1 dragging passive wheel to realize the dragging work, through the ultrasonic transducer and rolling embossing forcefully Press to make it generate high temperature, sew the hem on both sides of the fabric, and send it into the storage rack of the fabric after sewing. The storage rack presses down the incoming fabric and stores it. , the power micro switch cuts off the power supply of the driving motor A and the ultrasonic generator at the same time, so that the continuous dragging mechanism stops the dragging work; when the cloth in the storage rack is pulled out by the intermittent feeding mechanism, the storage rack will rise upwards, When leaving the power micro switch, the power micro switch continues to supply power, the driving motor and the ultrasonic generator of the continuous dragging mechanism resume work, and continue to maintain the work of continuous dragging. Then, the drive motor B of the intermittent feeding mechanism drives the feeding mechanism to do the intermittent feeding motion and the cutting work of the cutting mechanism by changing the speed at the same time. The electronic counter and the material sensor jointly control the power supply of the intermittent feeding mechanism, the continuous dragging mechanism and the ultrasonic generator to make it reach the preset quantity and when the fabric is used up, the power supply will be automatically cut off, realizing fully automatic cutting. Effect.

The beneficial effect of the present invention is: provide two 370W to 500W single-phase, 1400 rpm motors to drive the whole machine to work, cut 3000-6000 pieces of semi-finished handbag cloth in one hour, save electricity and reduce a lot of labor, save In the production process, the cost of tools and equipment for each process, and one worker can operate multiple seamless fabric automatic folding and cross-cutting machines at the same time, effectively and directly reducing the production cost.
