Description

Technical Field

[0001] The utility model mainly relates to the field of label production, and in particular to a drying device for label production. Background Art

[0002] A label is an additional identification card or brand for an object. In order to get a perfect quality label, in addition to configuring a high-quality barcode printer, the reasonable selection of label paper is also a very important link. At present, the barcode printer industry uses more self-adhesive labels. Self-adhesive labels are composed of three parts: release paper, face paper, and adhesive that serves as the bonding between the two. Release paper is commonly known as "base paper" and has an oily surface. The base paper has an isolation effect on the adhesive, so it is used as an attachment for the face paper to ensure that the face paper can be easily peeled off from the base paper.

[0003] In the invention patent application with application number CN202020919253.X, application publication date 2021.04.02, and name "A drying device for label production", it includes a shell structure, and two blocking structures are symmetrically installed at the front and rear ends of the shell structure. The blocking structure is composed of a blocking baffle, a connecting plate, an adjusting screw and a rotating column. The connecting plate is installed at the outer end of the blocking baffle, the adjusting screw is rotatably installed at the upper end of the connecting plate, and the rotating column is installed at the upper end of the adjusting screw. Two annular heating lamps are symmetrically installed in the shell structure, and a winding device is arranged at the rear of the shell structure. The device allows the label to pass through the annular heating lamps at the same time by arranging the annular heating lamps, and prevents the label from contacting other objects during the process of passing through the annular heating lamps and being dried.

[0004] However, the drying device has the following problems: when the label is heated for a long time by the annular heating lamp, when the top of the label is dried inside the device, the body below the label is easily heated and becomes brittle, and the drying angle of the label cannot be changed, resulting in uneven drying of the ink on the label surface.

[0007] 2. Technical solution:

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a drying device for label production, comprising a drying base box, an exhaust window is arranged on one side surface of the drying base box, a hollow conveying device is arranged above the drying base box, a cold air duct is arranged on one side of the hollow conveying device, a blower is arranged on the upper surface of the cold air duct, an upper sealing shell is arranged on the upper surface of the hollow conveying device, and a hot air adjustment structure is arranged on the upper surface of the hollow conveying device inside the upper sealing shell.

[0009] Furthermore, the blower is provided with two air outlet pipes, and exhausts air from the upper and lower ends of the hollow conveying device respectively through a hot air adjustment structure and a cold air duct, and the exhaust window is connected to the lower end of the hollow conveying device.

[0010] Furthermore, the hollow conveying device includes a hollow frame, a cold air chamber is arranged at the lower end of the hollow frame, a label slide is arranged on one side of the upper end surface of the hollow frame, a transmission motor is arranged at the lower end of the label slide, one end of the transmission motor is connected to a gear roller for transmission inside the hollow frame, gear rollers are arranged on both sides of the hollow frame, and the surface of the gear roller is meshed and linked with a rod-type conveyor belt.

[0011] Furthermore, the other end of the cold air duct is interconnected with the cold air chamber, the gear roller is rotated on both sides of the hollow frame through the transmission motor, and the rod-type conveyor belt forms a transmission structure on the upper surface of the hollow frame through the gear roller.

[0012] Furthermore, the hot air adjustment structure includes a cross-frame, an electric heating box is arranged on the upper surface of the cross-frame, a hot air inlet pipe is arranged above the electric heating box, side hanging plates are arranged on both sides of the surface of the cross-frame, a swinging bellows is movably connected to the inner surface of the side hanging plate, a transmission gear is arranged on one side of the swinging bellows on the surface of the side hanging plate, and a swinging motor is fixedly connected to the surface of one side of the side hanging plate.

[0014] 3. Beneficial effects:

[0015] The utility model has a reasonable design. When the ink on the label surface is dried, the printed label strip is placed on the surface of the label slide at one end of the hollow conveyor device, and the label strip is pushed into the surface of the rod-type conveyor belt. The transmission motor drives the gear roller and the rod-type conveyor belt, so that the rod-type conveyor belt drives the label strip to move toward the hot air adjustment structure. At the same time, the blower works to inject part of the extracted air into the cold air chamber through the cold air duct, so that the cold air cools the sticky part of the lower end of the label strip on the surface of the rod-type conveyor belt to prevent the label from being dried out due to heating of the body below the label. At the same time, the air is discharged from the exhaust window.

[0016] Under the action of the rod conveyor belt, the label strip passes under the swinging bellows in the hot air adjustment structure. At this time, the blower sends external air into the electric heating box through the hot air inlet pipe for heating. The heated air enters the swinging bellows at the lower end of the electric heating box. At this time, the swinging motor drives the half-tooth gear to rotate, and then drives the transmission gear and the swinging bellows to swing. Through the intermittent engagement of the half-tooth gear and the transmission gear, the swinging bellows is realized inside the cross-frame, thereby realizing the change of the wind direction of hot air drying, avoiding the uneven drying at a single angle.
