Description

Technical Field

[0001] The utility model relates to the technical field of label paper production, and particularly refers to a glue coating device for label paper production. Background Art

[0002] Label paper is a consumable used in barcode printers and is mainly used for label printing. The content that can be printed on it includes text, numbers, pictures, one-dimensional barcodes, two-dimensional barcodes, etc. In actual production, label paper refers to blank self-adhesive paper for printing labels, which consists of three parts: release paper (base paper), face paper, and an adhesive as the binder between the two. The surface of the release paper (base paper) is oily and has an isolating effect on the adhesive, serving as the attachment body for the face paper to ensure that the face paper can be easily peeled off from the base paper. The back is coated with an adhesive, which on the one hand ensures the appropriate adhesion between the base paper and the face paper, and on the other hand ensures that after the face paper is peeled off, it can have a strong adhesiveness with the object to be pasted.

[0003] In the process of label paper production, glue coating is a key step, which is used to evenly apply glue on the back of the label paper for subsequent pasting operations. Existing glue coating devices include a glue storage tank, a nozzle, and a control unit. The glue storage tank is used to store glue, the nozzle is used to spray the glue on the back of the label paper, and the control unit is used to control the spraying speed and flow rate of the nozzle. However, the glue is prone to accumulation after spraying, resulting in uneven coating, affecting the use. And the label paper after coating needs to be taken off before continuing the glue coating work. The existing device does not have an automatic winding function, resulting in low continuity and affecting efficiency. Therefore, a high-efficiency and evenly coated glue coating device for label paper production is needed. Content of the Utility Model

[0006] As an improvement, a chute is arranged on one side of the support rod close to the glue extrusion plate, and a limiting plate fixedly connected to the glue extrusion plate is slidably arranged in the chute, which is convenient for supporting and limiting during the glue coating process and improves stability.

[0007] As an improvement, a set of first clamping rings for clamping on both sides of the storage paper roll are arranged on the winding rod, a set of second clamping rings for clamping on both sides of the release paper roll are arranged on the limiting rod, the first clamping ring is dimensionally matched with the winding rod, and the second clamping ring is dimensionally matched with the limiting rod. The first clamping ring and the second clamping ring can limit and fix the storage paper roll and the release paper roll to prevent them from sliding, and facilitate the loading and unloading of the storage paper roll and the release paper roll.

[0008] As an improvement, a second extension plate close to the release rod is fixedly arranged on the right outer wall of the glue extrusion plate, and a cleaning felt closely attached to the surface of the label paper body is pasted on the bottom surface of the second extension plate, which can remove the surface dust of the label paper body before glue coating and ensure the glue coating effect.
