Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, and in particular to a high-precision flat labeling machine for cardboard boxes that can automatically load and unload materials. Background Technology

[0002] In the medical, food, and liquid beverage packaging industries, it is common to affix self-adhesive labels to the flat surfaces of cardboard boxes, requiring high labeling accuracy at specific locations. Currently, baffle-type ply labeling machines are commonly used for this purpose. However, their drawback is that they can only handle a limited number of boxes at a time, requiring frequent loading. The labeling mechanism of this common baffle-type ply labeling machine involves direct peeling of the label during its movement, resulting in relatively low labeling accuracy.

[0003] Therefore, conventional baffle-type ply labeling machines suffer from frequent feeding, high labor intensity, and insufficient labeling accuracy. They are unsuitable for the requirements of modern intelligent manufacturing and also affect product production management and sales. Developing a high-precision flat labeling machine for cardboard boxes with automatic feeding and unloading is essential, especially for meeting the requirements of high-precision flat labeling on cardboard boxes. Summary of the Invention

[0004] To address the shortcomings of existing labeling technologies, this invention provides a high-precision flat labeling machine for cardboard boxes with automatic loading and unloading capabilities, solving the problems of high labor intensity during loading and low labeling accuracy on cardboard boxes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A high-precision flat labeling machine for cardboard boxes with automatic loading and unloading includes a frame, a loading and unloading trolley, a loading and unloading lifting device, a cardboard box adsorption and conveying device, a labeling conveying device, a label station position adjustment device, and a retractable label feeding device. The retractable label feeding device is installed on the label station position adjustment device.

[0007] The retractable label feeding device includes a bottom fixed plate, a large upright plate, a support plate, an unwinding reel, a main drive roller, a take-up reel, a label pressure roller, a chain drive mechanism, a servo motor, a rodless cylinder, a cylinder mounting plate, a label peeling plate, a movable roller, a U-shaped sheet metal part, a label steering roller, a linear slide rail, a slider, a small plate, a guide rod, a linear bearing, a label suction plate, a compression spring, and a single-rod cylinder.

[0008] The large vertical plate is installed vertically to the bottom fixed plate. The unwinding reel and the winding reel are installed in front of the large vertical plate. The servo motor is installed vertically in front of the large vertical plate. The chain drive mechanism is located behind the large vertical plate and provides rotational power to the main drive roller and the winding reel.

[0009] A label pressure roller is also provided on one side of the main drive roller. The cylinder barrel of the rodless cylinder is fixedly connected to the cylinder mounting plate. The cylinder mounting plate is fixedly installed to the large upright plate. A label peeling plate is fixedly installed at the right end of the piston rod of the rodless cylinder, and the movable roller is installed at the left end of the piston rod of the rodless cylinder through a U-shaped sheet metal part. The label steering roller is installed between the drive roller and the rodless cylinder.

[0010] The support plate is fixed to the large vertical plate, and the slider is installed on the right side of the support plate. The linear slide rail slides in cooperation with the slider. The small plate is fixedly connected to the bottom end of the linear slide rail, and simultaneously floatingly connected to the piston rod end of the single-rod cylinder. The cylinder body of the single-rod cylinder is fixedly connected to the support plate.

[0011] A linear bearing is also fixedly installed on the small plate. A guide rod passes through the linear bearing, and a label suction plate is fixedly installed at the bottom end of the guide rod. A compression spring is fitted on the guide rod and located between the label suction plate and the small plate.

[0012] Preferably, the label station position adjustment device is located above the labeling conveying device and includes a left vertical plate, a right vertical plate, a horizontal plate, a servo motor, a drive pulley, a synchronous belt, a driven pulley, an adjusting screw, a linear slide rail, a slider, a screw nut seat, a screw nut, and a bearing. The left vertical plate, the right vertical plate, and the horizontal plate are fixedly connected to each other.

[0013] The servo motor is fixedly mounted on the inner side of the left vertical plate, and the active synchronous pulley is mounted on the output shaft end of the servo motor. A synchronous belt connects the active pulley and the passive pulley. The passive pulley is fixedly mounted on the left end of the adjusting screw.

[0018] Furthermore, the labeling conveyor is mounted on the frame platform.

[0019] Beneficial effects of this utility model

[0020] This invention features a retractable label feeding device. Unlike conventional label feeding devices, it does not directly peel off the label. Instead, it uses a rodless cylinder. When peeling off the label, the rodless cylinder pushes out to the right. After the label suction plate picks up the label, the rodless cylinder retracts to the left, and the label is peeled off. Its advantage is that during the label peeling process, the label is picked up and fixed by the label suction plate, and its position does not change, thus improving the labeling accuracy.

[0021] This invention also includes a label station position adjustment device. The retractable label feeding device is mounted on the slider via a bottom fixing plate. The servo motor drives the adjusting screw to precisely adjust the coordinate position of the retractable label feeding device. This invention also includes a loading and unloading trolley, which can store more cartons at once, reducing the labor intensity of the operators.

[0022] This invention fills the gap in existing labeling technology, realizes automatic loading and unloading, and performs high-precision labeling on the flat surface of cartons, effectively reducing labor costs and improving the economic benefits of enterprises. Attached Figure Description
