Description

Technical Field

[0001] The utility model relates to the technical field of pressure-sensitive adhesive spraying, in particular to a pressure-sensitive adhesive spraying device. Background Art

[0002] Pressure-sensitive adhesive is a viscoelastic body that possesses both the viscous properties of a liquid and the elastic properties of a solid. This viscoelastic body has the ability to withstand both the contact process and the destruction process of bonding.

[0003] In recent years, with the expansion of demand for packaging, decoration, office supplies and various labels, people's demand for pressure-sensitive adhesives has also increased. Acrylic pressure-sensitive adhesive emulsions have become the development direction of pressure-sensitive adhesives because they are non-toxic, non-polluting, and have excellent aging resistance, weather resistance, pressure sensitivity and adhesion, and have been widely used. In view of the characteristics of pressure-sensitive adhesives that are easy to adhere, easy to peel, not damaged, and will not dry up for a long time, while selecting the main monomer and second monomer of acrylic esters, a variety of functional group monomers are introduced. Through repeated experiments and reasonable adjustment of process formulas, a multi-copolymer acrylic ester pressure-sensitive adhesive emulsion with good comprehensive performance is screened and synthesized, which can be used in the production of double-sided tapes, trademark papers, etc. that require transfer coating processes. In addition, acrylic pressure-sensitive tapes, double-sided tapes, protective tapes, masking tapes, label tapes and medical tapes have greatly improved not only in terms of output, but also in terms of bonding and coating properties.

[0004] However, the existing pressure-sensitive adhesive spraying device cannot automatically adjust the spraying amount according to the width of the tape when facing tapes of different widths, resulting in excessive or insufficient spraying and waste of resources. Therefore, it is necessary to design a pressure-sensitive adhesive spraying device that can automatically adjust the spraying amount. Utility Model Content

[0024] Working principle:

[0025] The transmission device transports the label paper to the bottom of the injection head 13, loosens the fixing screw 5, adjusts the pressure roller 8 to move downward until the pressure roller 8 presses the label paper, tightens the fixing screw 5 to position the pressure roller 8, and the laser transmitter emits a laser downward and measures the length of the laser emission. The length of the laser emitted to the surface of the label paper is set to be q. When the partial laser sensor 12 detects that the length of the emitted laser is equal to q, the solenoid valve 11 opens, and the pressure-sensitive adhesive flows out of the injection head 13 and drips on the surface of the label paper. When the remaining laser sensor 12 detects that the length of the laser is greater than q, it means that there is no label paper under the injection head 13, and the solenoid valve 11 opens. The magnetic valve 11 is continuously closed, and the pressure roller 8 presses the pressure-sensitive adhesive sprayed on the surface of the label paper evenly. After a long time, the pressure-sensitive adhesive is sprayed on the surface of the label paper. The liquid level sensor 10 detects that the pressure-sensitive adhesive liquid level value inside the storage barrel 1 reaches 0, and the alarm 14 sounds to remind the staff to add pressure-sensitive adhesive to the storage barrel 1. The laser sensor 12 detects the distance from the emitted laser to the surface of the label paper to determine whether there is label paper under the injection head 13, thereby automatically opening or closing the solenoid valve 11 to adjust the injection amount of the pressure-sensitive adhesive, thereby achieving the effect of automatically controlling the spraying amount.
