A label induction cutting device

technical field

The utility model relates to a garment processing device, in particular to a device for automatically cutting labels.

Background technique

In the apparel industry, labels for clothes are printed in rolls with the same width between each label. In actual use, the roll of labels needs to be cut into individual labels for sewing. At present, the operation of garment factories is manual cutting, or cutting by length transmission. If a label is cut to the wrong length, it will directly affect the size of the next label. Especially for machines with automatic label cutting, this effect is more serious. After long-term research and many years of technical experience, the utility model has designed a label induction shearing device with high precision, wide processing range and self-adaptive ability.

The scrolling device includes an upper roller, a lower roller and a motor which are shelved oppositely, and the motor drives the upper roller to rotate through a transmission device, and the controller controls the operation of the motor.

The transmission device is a synchronous belt.

The cutting device is a cutting scissors, and the cutting scissors are composed of a moving knife and a fixed knife arranged on the knife holder shaft.

A spring is arranged on the tool holder shaft, and the movable knife and the fixed knife are tightly fitted under the spring extrusion.

The cutting scissors are driven by cylinders.

The set distance is the distance between the color difference sensor and the cutting device.

The other side of the feeding plate relative to the rolling device is provided with a pressing rod.

The label tape on the feeding plate is also provided with a pressing material smoothing block, which is eccentrically hinged on the rotating rod, and the pressing material smoothing block is lightly pressed on the label tape under the action of gravity.

The beneficial effects of the utility model are:

1. Strong adaptability, can cut trademarks of different lengths.

2. It has self-adaptive ability. The tension spring is installed on the tool post shaft. Even if the moving knife and the fixed knife are worn after working for a long time, the tension spring can ensure the position of the moving knife and the fixed knife.

3. The shearing action is completed by the cylinder, and the energy consumption is very low.

4. The motor and the color mark sensor act synchronously, with high precision.

5. Automated process, compared with manual feeding, can improve work efficiency.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

Example 1

As shown in Figure 1, a label induction shearing device includes a machine table with a feeding plate 8, a label roll storage device 6 is provided on one side of the machine table, and a label roll 4 is stored on the label roll storage device 6. , the label roll 4 is wound by a label tape 9, the structure of the label tape 9 is shown in Figure 2, the label tape 9 has a plurality of single labels arranged at a certain distance, and the gap between adjacent single labels is the label Segment mark 10. One end of the feeding plate 8 is provided with a pressure rod 7, and the other end is provided with an upper roller 11 and a lower roller 15 placed opposite to each other. The label tape 9 coming out of the label roll 4 is pasted on the upper surface of the feeding plate 8 after being turned by the pressure rod 7. Move forward and enter between the upper roller 11 and the lower roller 15, the outer sides of the upper roller 11 and the lower roller 15 are provided with cutting scissors 1.

One side of the feed plate 8 in the moving direction of the label tape 9 is provided with a blocking plate, and the color difference sensor 2 is arranged on the side of the blocking plate near the feed plate 8, and the color difference sensor 2 is just above the label tape 9. A controller 3 is arranged on the back of the blocking plate, the color difference sensor 2 is electrically connected to the controller 3, and the color difference sensor 2 transmits the perceived color difference signal to the controller. The back side of the blocking plate is also provided with a cutting cylinder 5, which is used to drive the cutting scissors 1.

Be positioned at the label band 9 on the feeding plate 8 and be also provided with pressing material smoothing block 12, pressing material smoothing block 12 is eccentrically hinged on the rotating rod 14, and rotating rod 14 is fixed on the blocking plate, owing to be eccentric setting, like this Under the action of gravity, one end of the pressing material smoothing block 12 will lightly press on the label tape 9, which can smooth the label and prevent the label from wrinkling and causing detection errors by the color difference sensor 2.
