The fabric is sent to the label feeding device 3 for labeling, and the subsequent label will be sewn onto the fabric together with the edge strip.

The two hemming devices 5 are arranged in the frame 1, and the two hemming devices 5 are respectively arranged on the laterally opposite sides of the two hemming tables 100. In this embodiment, one hemming device 5 is located on the lateral left side of the left side hemming table 100, and another hemming device 5 is located on the lateral side of the right side hemming table 100. The hemming device 5 and the corresponding hemming table 100 are laterally distributed based on the feeding device 2 .

The rotating mopping device 6 is movably disposed between the hemming table 100 and the fixed-length label feeding table 101, and is used to drag the fabric from the fixed-length label feeding table 101 to the hemming table 100 and then cooperate with the hemming device to mop the fabric. Rotary hemming is performed, and at the same time, the hemmed fabric is sent to one side of the subsequent collecting device 7 to facilitate the collecting of the material by the collecting device 7 .

The two collecting devices 7 are respectively arranged on one side of the two corresponding hemming tables 100 to collect the finished products.

In the double-head rotary hemming machine of the present invention, the fabrics sent out from the feeding device 2 are fixed by the mop-length fixing device 4 on the fixed-length label-feeding table and after the label is sent, the fabric is dragged by the rotating mop device 6 to the fixed-length label-feeding table. At the hemming tables on both sides of the table, the fabrics are hemmed through the hemming devices 5 set transversely on one side of the hemming table 100 to fully automatically complete the hemming operation of multiple fabrics after cutting, and finally perform automatic Receive materials.

At the same time, since the whole composed of two hemming tables 100 and two hemming devices 5 is placed horizontally based on the position of the feeding device 2, the structure of the double-head hemming machine is compact and the equipment occupies a small area; in addition, because The hemming table and the hemming device are located on both sides of the fixed-length label feeding table 101. The processing position of the hemming device and the hemming table are vertically arranged. The hemming table and the fixed-length label sending table are vertically arranged parallel to each other. In this way, large-sized fabrics can be placed on the hemming table for rotation, and the processing range is wide.

In this embodiment, based on Figure 3, the feeding device 2 includes a feeding seat 20. The feeding seat 20 is provided with a feeding wheel 21 and an active feeding wheel 22 arranged front and back. The active feeding wheel 22 is driven by a feeding motor. 24 is driven to rotate, and a plurality of spaced and linearly distributed pressing rollers 23 are installed above the active feeding wheel 22. The active feeding wheel 22 and the pressing roller 23 cooperate to transmit the fabric forward from the feeding wheel 21 to the auxiliary roller. 25, and then transmitted to the subsequent mop length fixing device 4.

In this embodiment, based on Figures 4 to 5, the mop length fixing device 4 includes a cloth pressing assembly 40, a shearing assembly 41, a pressing assembly 42 and a mop clip assembly 43; the cloth pressing assembly 40 is provided on the The fixed-length label delivery table 101 is located at the rear end of the feeding device 2; the rear end of the cloth pressing assembly 40 is provided with a shearing assembly 41 for cutting fabrics, and the rear end of the shearing assembly 41 A pressing component 42 for pressing the fabric is provided.

The pressing assembly 42 includes a pressing block 421 that can be lifted up and down through two oppositely arranged pressing cylinders 420. The two pressing blocks 421 are driven by the pressing cylinder 420 to move downward to compress the fabric at a fixed length. On the labeling table 101; the mop clamp assembly 43 can move longitudinally on the fixed-length labeling table 101, and is used to drag the fabric from the cloth pressing assembly to the rear of the fixed-length labeling table for fixed length, mopping The clamp assembly 43 is a common mechanism and will not be described here.

There are two types of shearing components 41 in this embodiment. One is based on Figure 5 and includes a shearing bracket 411 that can be moved laterally through a lateral movement module 410. The shearing bracket is provided with a shearing motor. 412 is a rotatable shearing knife 413, so that the shearing knife 413 can be rotated by the shearing motor 412 to perform a transverse shearing operation on the fabric through the transverse movement module 410. This shearing component 41 only has a shearing function.

During operation, the fabric is first transferred from the feeding device 2 to the pressing assembly 40, and then passes through the pressing assembly 42, and then the mop clamp assembly 43 drags the fabric backward on the fixed-length label delivery table 101. When the length of the fabric is fixed, Finally, the cloth pressing component and the pressing component simultaneously press the fabric, and then the shearing knife 413 cuts off the fabric. After cutting, the fabrics at both ends are fixed by the cloth pressing component and the pressing component respectively. Then the pressing component is released, and the mop clamp assembly 43. Continue to drag the cut fabric back on the fixed-length label feeding table 101 to the label feeding device 3 for labeling.

The other is based on the shearing assembly described in Figures 6 to 10. The shearing assembly includes a base 31, an ultrasonic module 32, a cloth cutting assembly 33, a driving mechanism 34 and a feeding table 35; the ultrasonic module 32 is provided at On the base 31; the cloth cutting assembly 33 is also installed on the base 31 and is located above the ultrasonic module 32. The cloth cutting assembly includes a roller 330, and the roller 330 is provided with a length along the circumference of the roller. The cutter part is arranged in the direction; the cloth cutting component 33 is driven by the driving mechanism 34 to make eccentric movement above the ultrasonic module 32. When the cloth cutting component 33 moves to a certain position, it will be located above the ultrasonic module 32 in conjunction with the ultrasonic module 32. The fabric is cut; the feeding table 35 is located at the front end of the base 31 for transmitting the fabric to between the ultrasonic module 32 and the cloth cutting assembly 33 .

Based on FIGS. 8 to 10 , in this embodiment, the cutter part includes a linear cutter 331 along the length direction of the roller 330 and disposed in the circumferential direction of the roller. The two ends of the cutter 331 are respectively There is an arc-shaped cutter 332 extending to both sides. The two arc-shaped cutters 332 on the same side are in the shape of a "herringbone". In this way, the strip cutting knife 331 and the arc-shaped cutter 332 cooperate with each other and can be cut twice. Produce fabric with four rounded corners.

In addition, a cutting knife 333 extends from each arc-shaped cutter 332. The cutting knife 333 is used to prevent the strip cutting knife 31 and the four arc-shaped cutters 32 from not cutting the fabric into two pieces.

Based on Figure 7, the driving mechanism 34 includes a power motor 340. The power motor 340 drives the cloth cutting assembly 33 to rotate eccentrically above the ultrasonic module 32 through the cam 341. In this way, when the cloth cutting assembly 33 drives the cam 341 to rotate eccentrically, When the cloth cutting component 33 is in the initial state, it is not in contact with the fabric. When the cloth cutting component 33 rotates to a certain position, the cloth cutting component 33 cooperates with the ultrasonic module 32 to cut the fabric; when in contact, the cutting knife 331 cuts the fabric. The middle is cut in a straight line, and at the same time, the four arc-shaped cutters 332 cut the two corners of the opposite sides of the two fabrics formed after being cut by the strip cutter 331 into rounded corners.

In this embodiment, the cloth cutting assembly 33 is disposed on the moving block 37. The moving block 37 moves up and down above the ultrasonic module 32 through the adjusting bolt 38 on the base 31, so that the cloth cutting assembly 33 can be automatically adjusted. The distance between the ultrasonic module 32 and the ultrasonic module 32 is suitable for fabrics of different thicknesses.

Based on Figures 6 to 10, the following is a detailed description of the process when the cutter part is the strip cutting knife 331 and the arc cutter 332 for the cutting operation:

S1. The fabric flows from the feeding table 35, and then enters between the cloth cutting assembly 33 and the ultrasonic module 32;

S2. The fabric is dragged backward by the mop clamp 43. During the process of the mop clamp 43 dragging the fabric backward, the speed of the mop is constant; at this time, the rotation speed of the roller 330 is used to determine the length of the cloth cutting assembly 3 after cutting. The length of the fabric, relatively speaking, the faster the roller speed, the shorter the length of the fabric after cutting; the slower the roller speed, the longer the length of the fabric after cutting;

S3. In the initial state, the front end of the fabric is cut, so the speed of the roller 330 is relatively fast. When the mop clip 43 drags the fabric away for a short distance, the roller 330 rotates eccentrically driven by the cam and the power motor 40, causing the strips to be cut. The knife 331 and the four arc-shaped cutters 332 just cooperate with the ultrasonic module 2 to cut the fabric, and the fabric 80 is cut into the left fabric and the right fabric, and the two corners of the opposite sides of the left fabric and the right fabric are round. corner, the two pieces of fabric at this time are shown in Figure 10; then the roller 330 continues to drive the left fabric to move forward for a certain distance to facilitate the subsequent capture of the mop clip. The right fabric is manually taken out from the mop clip, and then the mop clip 43Clamp the fabric on the left side again;

S4. When the mop clamp 43 drags the fabric on the left side to move backward, the fabric is cut off by using the eccentrically moving cloth cutting component 3 and the ultrasonic module 32, thereby dividing the fabric on the left side into two fabrics again, thus cutting. A fabric to be processed later is produced. The four corners of the fabric are all rounded. This enables the fabric to be cut and its four corners to be rounded at the same time. The processing is completed in one step, which facilitates subsequent direct processing.

The shearing assembly in this embodiment can directly cut the fabric into round edges, so that there is no need to use the subsequent trimming cutter 58 to trim the fabric. However, due to the cutter assembly in this embodiment It is cut using an ultrasonic module, which can only be applied to fabrics of about 40cmx40cm. Fabrics larger than 40cmx40cm still need to use the first shearing component in conjunction with the subsequent trimming and cutting knife 58 to round the corners of the fabric. .

In addition, different shapes of cutting blades can be used to cut different fabrics, such as:

Based on Figure 11, this embodiment is provided with a triangular cutter arranged along the length direction of the roller 330 in the circumferential direction of the roller 330, so that a corresponding triangle-shaped fabric is finally cut out on the fabric.

Based on Figure 12, this embodiment is provided with a trapezoidal cutter arranged along the length direction of the roller 330 in the circumferential direction, so that a corresponding trapezoidal fabric is finally cut out on the fabric.

Based on Figure 13, this embodiment is provided with a circular cutter along the length direction of the roller 330 in the circumferential direction, so that a corresponding circular-shaped fabric is finally cut out on the fabric.

Of course, in actual situations, cutters of different shapes can also be designed to cut fabrics with different patterns, which will not be described here.

In addition, in this embodiment, the label delivery device can be divided into two ways to deliver labels. One is the conventional label delivery method, that is, the label is placed on top of the fabric through the label delivery device 3, and then the rotating mop device 6 is used to Move to the hemming device 5 for sewing with the hemming strip; another method is to place the label under the fabric, and then move it to the hemming device 5 with the rotating mop device 6 for sewing with the hem strip. The two different methods are to meet the needs of different customers for label location.

In this embodiment, based on Figures 1 and 14, the rotating mopping device 6 includes a rotating mopping bracket 61 that can move laterally and longitudinally above the work surface through a synchronized wheel slide assembly 60 and a longitudinal sliding module 65; The rotary mop support 61 is provided with a rotary motor 63 that can move up and down the rotary mop support 61 by moving the cylinder 62 downward. The rotary motor 63 drives the rotary pressure plate 64 to rotate above the work surface for moving fabrics. Press it onto the work surface 10 for 360° rotation.

Specifically, the rotating pressing plate 64 in this embodiment is in the shape of a long strip. The rotating pressing plate 64 is moved down above the fabric on the work surface 10 through the downward movement cylinder 62 and then compresses the fabric. At the same time, the rotating motor 63 is driven by the rotating pressing plate 64 The fabric is rotated 360° on the hemming table 100, which is used to cooperate with the subsequent hemming processing of 5 pairs of fabrics by the hemming device.
