Description

Technical Field

[0001] This invention relates to the field of label production technology, and in particular to an automatic edge-wrapping machine for square labels. Background Technology

[0002] An automatic label edge-binding machine is a specialized sewing device used for edge-binding and ironing of labels. Combining advanced electronic technology and precise mechanical design, this equipment enables high-speed, precise, and continuous operation, significantly improving production efficiency and product quality. Automatic label edge-binding machines are widely used in the manufacturing industries of clothing, footwear, bags, toys, and household goods. In the clothing industry, it is commonly used for edge-binding labels such as trademarks, collar labels, and sleeve labels; in the bag industry, it is used for edge-binding bag accessories and zipper labels. The automatic label edge-binding machine is a highly efficient, precise, and multifunctional processing device that plays a vital role in improving production efficiency and product quality.

[0003] Traditional automatic label edge-sealing machines use robotic arms and pushing mechanisms to transport and process labels. Labels come in various shapes, such as round and square, and are typically centered using push plates of specific shapes. However, it is difficult to center labels of different shapes during transport, making it hard for the robotic arm to align the center of different shaped labels. This causes the robotic arm to move the labels to the edge-sealing assembly, resulting in edge-sealing offset.

[0004] Traditional automatic label wrapping machines often encounter problems when using labels made of soft or thin materials. Simply pushing the labels with a pusher plate makes it difficult to center them properly and can easily cause label deformation, making alignment difficult. Therefore, developing an automatic square label wrapping machine that can adapt to different shapes and thicknesses, and can push labels with different shapes and thicknesses for easy alignment with the robotic arm, can solve these problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art mentioned above, such as the difficulty in centering labels of different shapes during transport, the difficulty in centering labels by simply pushing them with a pusher plate, the tendency to deform labels, the inability to quickly align labels, and the limited compatibility of the device itself.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic edge-sealing machine for square labels includes,

[0008] The device body has an edge-binding mechanism installed at its upper end; the air suction component at the bottom of the second robotic arm is aligned with the center of the label and grabs it to one end of the edge-binding component. The rotation of the second robotic arm, in conjunction with the edge-binding component, performs edge-binding processing on the square label.

[0009] A centering positioning mechanism is located at the upper end of the main body of the device for centering the label. The centering positioning mechanism includes a housing, a driving component at one end of the housing, a push rod at one end of the driving component, a lower fixed wheel at one end of the push rod, and inclined plates at both ends of the push rod. A positioning shaft is inserted inside the housing. A curved plate is rotated and limited by the positioning shaft. A pulley installed at the bottom of the curved plate rolls on the slope of the inclined plate, which drives the upper fixed wheel at one end of the curved plate to adjust and adhere to the label.

[0010] The lifting mechanism, located inside the housing, is used to lift labels. The lifting mechanism includes a connecting rod, one end of which is connected to a connecting plate. A slide rail is fixedly connected inside the housing, and one end of the slide rail is slidably connected to a sliding plate. A parallelogram groove is provided inside the sliding plate, and an embedded sliding buckle is inserted into the parallelogram groove. The support plate rises and falls, cooperating with the centering positioning mechanism to simultaneously lift and center the label.

[0011] Preferably, the edge-binding mechanism includes a label holder, a transmission rail is installed at one end of the main body of the device, a telescopic rod is connected to one end of the transmission rail, and a first robotic arm is connected to one end of the telescopic rod. The transmission rail is installed at one end of the main body of the device, and the telescopic rod is installed at one end of the transmission rail. After the telescopic rod extends and retracts, it drives the first robotic arm to wind-pick up the label from the label holder and place the label on the upper end of the main body of the device. The label is then centered by a centering positioning mechanism.

[0012] Preferably, a curved plate is installed at the upper end of the positioning shaft, a pulley is connected to one end of the curved plate, and an upper fixed wheel is installed at the other end of the curved plate. The upper fixed wheel at one end of the curved plate adjusts to fit the label, and while cooperating with the lower fixed wheel at one end of the inclined plate to clamp and push the square label, it adapts to the centering of labels of different diameters and shapes, so that the center height remains unchanged.

[0013] Preferably, the curved plate is installed in two sets, and the outer surface of the pulley slides in cooperation with the inclined plate. The curved plate is rotated and limited by the positioning shaft, and the pulley installed at the bottom of the curved plate rolls on the slope surface of the inclined plate, which drives the upper fixed wheel at one end of the curved plate to adjust and attach the label.

[0014] Preferably, one end of the embedded sliding buckle is connected to a pin, an elastic element is sleeved on the outside of the pin, and a support plate is connected to the outside of the elastic element. The support plate is installed at one end of the pin, so that the drive component drives the linkage to raise and lower the support plate. This, together with the centering positioning mechanism, lifts and centers the label simultaneously, facilitating centered contact with the robotic arm.

[0015] Preferably, the parallelogram groove is stepped, and one end of the slide plate slides in conjunction with the inside of the slide rail. The stepped design of the parallelogram groove ensures that the cyclic sliding of the embedded clip will not get stuck.

[0016] Preferably, the embedded sliding buckle slides into the parallelogram groove, the interior of the elastic element engages with the pin, and the pin is installed at one end of the embedded sliding buckle. Under the action of the elastic element, the elastic element and the parallelogram groove maintain a stable engagement. A support plate is installed at one end of the pin, so that the drive element drives the linkage, and the support plate rises and falls.

[0017] Preferably, a slider is slidably connected to the upper end of the transmission rail, and a slide rail is connected to one end of the slider. The slider at the upper end of the transmission rail drives the second robot arm to slide. The suction component at the bottom of the second robot arm is aligned with the center position of the label and grabs it to one end of the edge-binding component. The rotation of the second robot arm, in conjunction with the edge-binding component, performs edge-binding processing on the square label.

[0018] Preferably, a second robotic arm is slidably connected to the upper end of the slide rail, an edge-sealing component is installed at one end of the main body of the device, and a feeding ramp is provided at the upper end of the main body of the device, through which the labels fall into the collection box for collection.

[0019] Preferably, the lower end of the slider is slidably engaged with the transmission rail, and one end of the second robot is slidably engaged with the slide rail. The slide rail is installed at one end of the slider so that the second robot slides laterally on the slide rail.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention features an edge-binding mechanism installed at the top of the main body of the device. A first robotic arm uses airflow to pick up labels from a label box and places them on the top of the main body. After centering by a centering positioning mechanism, the second robotic arm rotates in conjunction with the edge-binding component to edge-bind the square labels. The centering positioning mechanism, installed at the top of the main body, drives a push rod to move back and forth after the drive unit is activated. By installing inclined plates at both ends of the push rod, a curved plate with a positioning shaft for rotation and limit is formed. A pulley installed at the bottom of the curved plate rolls on the slope of the inclined plate, causing the upper fixed wheel at one end of the curved plate to adjust and fit the label. In conjunction with the lower fixed wheel at one end of the inclined plate, the square label is clamped and pushed while the label is centered adaptively for labels of different diameters and shapes, keeping its center height constant.

[0022] Furthermore, a lifting mechanism is provided at the lower end of the centering positioning mechanism. When the drive component drives the push rod to push, the connecting rod at the bottom of the push rod connects to the connecting plate. A parallelogram groove is opened at one end of the slide plate, and an embedded sliding buckle is installed inside the parallelogram groove for sliding. A support plate is installed at one end of the pin shaft, so that the drive component drives the linkage, and the support plate rises and falls. In conjunction with the centering positioning mechanism, the label is lifted and centered at the same time, which facilitates the centering contact with the robotic arm. This achieves the effect of being able to push and center labels of different shapes and materials with different thicknesses, and is convenient for centering and aligning with the robotic arm.
