Description

Technical Field

[0001] This invention relates to the field of garment processing equipment technology. Specifically, it is a feeding machine specifically designed for use in garment production processes. It can achieve stable fabric conveying, automatic correction and flattening, adaptive tensioning, and synchronize the fabric roller with the feeding action. It is suitable for processing and feeding various knitted and woven garment fabrics. Background Technology

[0002] In the garment manufacturing industry, feeders are key equipment connecting cutting, sewing, and other processes. Their core function is to smoothly and neatly transport fabric to the next process. Currently used feeders have some problems.

[0003] Fabric is prone to deviation during conveying, especially for lightweight or elastic fabrics. Deviation leads to inaccurate dimensions during subsequent cutting and sewing, increasing the scrap rate. Fabric tends to wrinkle and clump together when passing through the feeder. Manually smoothing it out is not only time-consuming but also cannot keep up with the machine's conveying speed, affecting production efficiency. The tension of the fabric is difficult to adjust. Most existing devices have fixed tensioning structures and cannot adaptively adjust based on the fabric's thickness, elasticity, or the degree of deviation. The rotation speed of the fabric roller and the conveying speed of the feeder are often out of sync. After one end is independently tensioned, the fabric roll mandrel cannot make adaptive fine adjustments in sync with the fabric roller, resulting in different tensions on both sides of the fabric. When the fabric roller rotates fast, the fabric piles up; when it rotates slowly, the fabric is pulled. This affects the stability of the fabric roll mandrel's output and increases the probability of fabric wrinkles and deviation.

[0004] To solve these problems encountered in actual production, I designed this garment processing feeder, which integrates functions such as flattening, correction, tensioning, and synchronization adjustment, making fabric feeding more stable and precise. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding machine for garment processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding machine for garment processing, comprising a frame, an installation chamber, and a power chamber. A conveying section, a correction section, and a synchronization section are installed on the top of the frame. The conveying section feeds and straightens the fabric, the correction section flattens and tightens the fabric, and the synchronization section finely adjusts the positions of both ends of the fabric roll mandrel. The synchronization section and the correction section are synchronously and parallelly adjusted to ensure the correction effect while preventing the fabric roller from shifting further due to the different tensions on both sides of the fabric.

[0007] Furthermore, the conveying unit includes a fabric spreading mechanism, a fabric pulling mechanism, and a driving mechanism. The fabric spreading mechanism spreads the fabric to both sides and feeds it in a wave-like pushing manner. The fabric pulling mechanism intermittently pulls the fabric outward and straightens it. The driving mechanism provides power to the fabric spreading mechanism and the fabric pulling mechanism.

[0008] Furthermore, the fabric flattening mechanism includes a flattening roller, an annular rubber strip, and several arc-shaped seats and arc-shaped rubber strips. The annular rubber strip is fixed at the middle position of the outer wall of the flattening roller, and the arc-shaped rubber strip is fixed to the arc-shaped seats with glue. The arc-shaped seats are evenly fixed on the outer wall of the flattening roller, and the arc-shaped seats on both sides of the annular rubber strip are symmetrical.

[0009] Furthermore, the fabric pulling mechanism includes a conveying roller and several rubber strips, with the rubber strips evenly installed on the outer side wall of the conveying roller.

[0010] Furthermore, the drive mechanism includes a first drive motor, two drive wheels, a first driven wheel, and a second driven wheel. The first drive motor is fixed inside the power chamber. The two drive wheels are fixed at the output end of the first drive motor. The second driven wheel is fixed at one end of the conveying roller and is powered by a transmission belt. The first driven wheel is fixed at one end of the flattening roller and is powered by a transmission belt. The other ends of the two transmission belts are respectively connected to the corresponding drive wheels.

[0011] Furthermore, the correction unit includes a correction roller, a second drive motor, a rotating shaft, a first arc-shaped groove, and a push-pull tensioning mechanism. The correction roller is located at the top of the mounting chamber, the rotating shaft passes through and is fixed at the core of the correction roller, the first arc-shaped groove is formed on the mounting chamber and slides in cooperation with the rotating shaft, the second drive motor provides power to the correction roller, and the push-pull tensioning mechanism performs push-pull fine-tuning of the position of the correction roller to achieve tension adjustment of the fabric.

[0012] Furthermore, the push-pull tensioning mechanism includes a connecting chamber, a second arc-shaped groove, an arc-shaped slider, an electric telescopic push rod, and an L-shaped connector. The second drive motor is fixed inside the connecting chamber. One end of the connecting chamber is hinged to the electric telescopic push rod, and the other end of the electric telescopic push rod is hinged to the L-shaped connector. The other end of the L-shaped connector is fixed to the outer wall of the mounting chamber. The second arc-shaped groove is formed on the outer wall of the mounting chamber, and the second arc-shaped groove slides in cooperation with the arc-shaped slider. The arc-shaped slider is fixed to the outer wall of the connecting chamber.

[0013] Furthermore, the fabric synchronization mechanism includes a fabric support mechanism and a synchronization mechanism. The synchronization part includes a fabric roll core bearing support mechanism and a fabric roll core shaft synchronization mechanism. The fabric support mechanism supports both ends of the fabric roll core shaft, and the fabric roll core shaft synchronization mechanism performs fine-tuning of the position of the fabric roll core shaft in sync with the correction part.

[0014] Furthermore, the fabric roll core bearing support mechanism includes two fabric roll core shaft brackets and fabric roll core shaft guide grooves. The fabric roll core shaft brackets are all fixed to the frame by square steel, and the fabric roll core shaft guide grooves are all opened on the frame.

[0015] Furthermore, the synchronization mechanism includes a push rod, a guide rod, a third arc-shaped groove, and an arc-shaped push plate. The fabric roll mandrel synchronization mechanism includes a push rod, a guide rod, a third arc-shaped groove, and an arc-shaped push plate. The third arc-shaped groove is formed on the fabric roll mandrel bracket and slides in cooperation with the guide rod. The guide rod is fixed on the push rod. One end of the push rod is hinged to the connecting compartment and located on the side away from the electric telescopic push rod. The arc-shaped push plate is fixed to one end of the push rod and is adapted to the fabric roll mandrel.

[0016] Beneficial technical effects of the present invention: 1. The fabric spreading mechanism uses ring-shaped and symmetrical arc-shaped rubber strips to form a wave-like spreading effect. When the fabric passes through, it can spread out evenly to both sides, solving the problems of fabric wrinkling and stacking. In conjunction with the fabric pulling mechanism, it pulls while spreading out, further improving the stability of feeding. 2. The fabric tensioning mechanism drives the correction roller to adjust the angle through an electric telescopic push rod. It can adaptively adjust the tension according to the thickness, elasticity and degree of deviation of the fabric, and will not cause deformation due to excessive tension or slippage due to excessive looseness. The tensioning accuracy is higher, and the two ends of the correction roller can be adjusted independently. During the fabric correction process, by fine-tuning the tension on one side, in conjunction with the fabric flattening mechanism, the skewed fabric can be corrected and reset more quickly. 3. The synchronization mechanism follows the tensioning mechanism through the push rod, and synchronously fine-tunes the position of the fabric roll mandrel, so that the feeding speed of the fabric roll mandrel, the conveying speed of the feeder, and the tension on both sides of the fabric are consistent. Synchronization between feeding and fabric roller can prevent the fabric from being pulled or piled up, making the fabric roller output process more stable and reducing the magnitude of deviation.

[0031] In this embodiment, the core controller of the manufacturing system is a PLCS7-200SMART, which can store multiple sets of processing parameters for different fabrics and supports manual / automatic switching.

[0032] Working principle and usage process of this invention: Material preparation: Place the fabric roll mandrel on two fabric roll mandrel supports 25 through the fabric roll mandrel guide groove 28, and place the metal rods at both ends of the fabric roller on the supports. The arc-shaped push plate 27 is attached to the metal rods. Pull out one end of the fabric and pass it through the flattening roller 5, the conveying roller 3, and the correction roller 14 in sequence, and finally connect it to the next processing step. Start the equipment: Connect the power and air supply, set the speed of the first drive motor 10 and the second drive motor 18, and set the initial working pressure of the electric telescopic push rod 21 according to the thickness and elasticity of the fabric. Conveying and flattening: The first drive motor 10 starts and drives the conveyor roller 3 and flattening roller 5 to rotate via the synchronous belt. The rubber strips 4 on the conveyor roller 3 intermittently pull the fabric forward. At the same time, the flattening roller 5 rotates, and the annular rubber strip 6 in the middle and the arc-shaped rubber strips 8 on both sides form a wave-like contact surface. When the fabric passes by, it is evenly spread to both sides and the wrinkles are smoothed out. Tensioning adjustment: The second drive motor 18 drives the correction roller 14 to rotate, cooperating with the conveying of the fabric; during the feeding process, the position is detected by the correction sensor (model E3Z-LS63). If the fabric is too loose, the electric telescopic push rod 21 retracts, driving the connecting bin 17 to slide in the second arc groove 19 through the arc slider 20, and the rotating shaft 15 of the correction roller 14 moves in the first arc groove 16, adjusting the angle of the correction roller 14, and the fabric is moderately tightened; if the fabric is too tight, the electric telescopic push rod 21 extends, the correction roller 14 adjusts in the opposite direction, and the tension decreases, achieving adaptive adjustment. During the feeding process, the different heights at both ends of the correction roller 14 can be adjusted according to the skew situation to achieve rapid correction. After the correction is completed, the correction roller 14 resets. Synchronous fine adjustment: When the electric telescopic push rod 21 moves the connecting chamber 17, the push rod 23 follows the action, the guide rod 24 slides in the third arc groove 26, and the arc push plate 27 pushes the fabric roller to move slightly, adjusting the feeding angle and speed of the fabric roller so that the feeding speed of the fabric roller is consistent with the conveying speed of the feeder, thus avoiding the fabric being pulled or piled up. Continuous processing: The equipment runs continuously, and the fabric is smoothly, flat and wrinkle-free transported to the next process with the cooperation of the conveying unit, flattening mechanism, tensioning mechanism and synchronization mechanism until a roll of fabric is processed. Material changing operation: After processing a roll of fabric, turn off the power and air supply of the equipment, remove the empty fabric roller from the fabric roll mandrel bracket 25, put the new fabric roller into the fabric roll mandrel guide groove 28, repeat the material preparation steps, and you can continue processing.
