Description

Technical Field

[0001] The utility model belongs to the technical field of packaging and printing, and particularly relates to a glue brushing device for packaging and printing. Background Art

[0002] Package printing refers to printing using various packaging materials as carriers, by printing decorative patterns, designs or texts on the packaging to make the product more attractive or more descriptive. If glue brushing is required during the operation of the packaging printing equipment, a glue brushing device is required.

[0003] The existing glue brushing device generally adopts a fixed-point dripping method to add glue liquid. However, this feeding method cannot achieve uniform glue coating on the entire surface of the glue coating roller. Therefore, in the subsequent packaging printing, there will be a problem of local lack of glue and hollow bonding. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a glue brushing device for packaging printing, so as to solve the problem in the prior art that the existing glue brushing device cannot achieve uniform coating on the entire surface of the glue coating roller when adding glue.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a glue-brushing device for packaging and printing, comprising a symmetrically arranged mounting frame, inside which a conveyor belt for conveying packaging and printing articles is arranged; a mounting frame, which is mounted on the mounting frame, and a glue-spreading roller is also arranged inside the mounting frame. During the gluing process, the packaging is glued by the glue-spreading roller and the packaging placed on the conveyor belt, and then the packaging is transferred to the next printing process through the conveyor belt; a glue-spreading assembly is also provided inside the mounting frame, and the glue-spreading assembly consists of a glue-spraying part and a sealing part, wherein the glue-spraying part The part is located directly above the glue coating roller, and both ends are connected to the inner wall of the mounting frame. Specifically, it can be fixed by bolts, which can also facilitate later disassembly. The blocking piece is arranged between the glue injection part and the glue coating roller, and fits with the glue injection part, and is separated from or fits with the glue coating roller. When the blocking piece blocks the glue injection part, it will not be connected to the glue coating roller. Conversely, when the blocking piece fits with the surface of the glue coating roller, it will not block the glue injection part. The two ends of the blocking piece are slidably fitted with the inner wall of the mounting frame, thereby ensuring the movement of its own position and fitting with the glue injection part or the glue coating roller.

[0006] Preferably, the glue injection part includes a liquid accumulation bucket, the inner diameter of which shrinks from the top to the bottom. This structural setting can quickly discharge the glue during glue discharge, and can discharge it in a "one" shape and flush, avoiding the phenomenon of local glue not being discharged; a drainage groove is also provided on the top of the mounting frame, and the drainage groove is located directly above the liquid accumulation bucket, so that the glue can be discharged into the liquid accumulation bucket.

[0007] Preferably, a glue groove is placed on the top of the installation frame, and a liquid outlet groove connected to the liquid drainage groove is opened at the bottom of the glue groove. During use, the glue stored in the glue groove will be discharged into the liquid outlet groove through the liquid drainage groove.

[0008] Preferably, the sealing member includes a functional plate having a horizontal portion that fits with the bottom end of the liquid hopper and an inclined portion that fits with the surface of the glue coating roller. A liquid guide groove is provided on the horizontal portion of the functional plate, and the cross-section of the liquid guide groove is equal to the cross-sectional area of the bottom end of the liquid hopper and has the same shape.

[0009] Preferably, an adjusting column is fixed to one end of the horizontal portion of the functional plate, and a movable groove for the adjusting column to move is opened on the side of the mounting frame. When the adjusting column moves to one end of the movable groove in the x direction, the liquid guide groove is aligned with the bottom end of the liquid accumulation bucket. At this time, the functional plate no longer blocks the liquid accumulation bucket, thereby realizing normal discharge of the glue to the glue coating roller. At the same time, the inclined portion of the functional plate fits with the glue coating roller, which can further evenly apply the glue to the glue coating roller. When liquid injection is not needed, the adjusting column is moved to one end of the movable groove in the y direction, and the liquid accumulation bucket is blocked by the horizontal portion of the functional plate, and the inclined portion of the functional plate is separated from the glue coating roller.

[0010] Preferably, one end of the glue coating roller is connected to a motor, which is installed on the side of the installation frame to drive the glue coating roller to rotate.

[0011] Preferably, a limit block is further installed on the top surface of the installation frame, and the glue groove is placed in the limit block to achieve quick installation.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The designed gluing component can evenly scrape glue on the surface of the gluing roller when adding glue to the surface of the gluing roller, avoiding the phenomenon of hollowing and looseness in the packaging and printing in the later stage due to lack of glue in some parts of the gluing roller. This improvement improves the shortcomings of the existing structure. At the same time, the gluing component has a simple structure, is easy to process and produce, and has high practicality as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
