Description

Technical Field

[0001] The utility model belongs to the technical field related to the production of packaging products, and particularly relates to a glue coating roller for honeycomb paper cores. Background Art

[0002] Among the packaging products, various cartons are the most common, and cartons are formed by various paperboards. Honeycomb paperboard is made by bonding honeycomb paper core and face paper. Honeycomb paperboard is made according to the principle of natural honeycomb structure. It is a new type of sandwich structure that connects corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral honeycomb paper core, and glues face paper on both sides. In the bonding process of the honeycomb paper core and the face paper, it is necessary to apply adhesive to assist bonding. Usually, a glue roller is used to adhere glue liquid or adhesive for gluing. However, the glue roller still has the following disadvantages in actual use:

[0003] 1. When the conventional glue coating roller is applied to the surface of the honeycomb paper core, the glue coating roller is usually immersed in the glue solution, and then rotated to apply glue to the honeycomb paper core passing by. However, this method can only apply glue to one side of the honeycomb paper core, and cannot be applied to both sides at the same time, which affects the efficiency of the glue coating process;

[0004] 2. Secondly, if you want to apply glue on both sides at the same time, when applying glue to the upper layer of the honeycomb paper core, the glue roller should be located above the honeycomb paper core, which makes it difficult to dip the glue. If the glue is directly poured on, it will cause a large amount of glue to accumulate too much, resulting in great waste, so it needs to be improved. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1-7As shown, the utility model is a glue coating roller for honeycomb paper core, comprising an upper roller 2 and a lower roller 3, wherein the upper roller 2 is located above the lower roller 3, and a horizontally placed semi-cylindrical glue groove 1 is arranged below the lower roller 3, and both ends of the top surface of the glue groove 1 are fixed with an inverted U-shaped mounting frame 4, and the upper roller 2 and the lower roller 3 are distributed between the two mounting frames 4;

[0031] The glue tank 1 is used to store a certain amount of glue liquid, and the mounting frame 4 is used to assist in mounting an upper roller 2 and a lower roller 3 for gluing. The upper roller 2 is used to apply glue to the upper surface of the honeycomb paper core, and the lower roller 3 is used to apply glue to the lower surface of the honeycomb paper core.

[0032] A large number of soft bristles 201 distributed in an annular array are fixed through the circumference of the upper roller 2; a threaded ring block 301 is screwed on the circumference of the lower roller 3, and hard bristles 3011 are fixed in an annular array on the outer circumference of each threaded ring block 301;

[0033] The upper roller 2 contains glue liquid, which can be more conveniently soaked through the design of soft bristles 201, so that the glue liquid flows to the soft bristles 201, and the glue liquid is better guided out to facilitate the use of glue brushing; the outer periphery of the lower roller 3 is screwed through the threaded ring block 301, and the spacing and number can be appropriately adjusted. The hard bristles 3011 outside the threaded ring block 301 are more convenient to dip the glue liquid stored in the glue tank 1, and are convenient to brush on the lower surface of the honeycomb paper core after being stained with glue;

[0034] One end of the upper roller 2 is rotatably connected to a rubber inlet pipe 5 for conveying external glue liquid into the upper roller 2 for use.

[0035] A fixed base block 401 is fixed to the inner bottom of the installation frame 4, a movable base block 402 is slidably arranged in the installation frame 4 above the fixed base block 401, and bearing seats 404 are fixed in both the movable base block 402 and the fixed base block 401, the two ends of the upper roller 2 are rotatably connected to the bearing seats 404 in the two movable base blocks 402, and the two ends of the lower roller 3 are rotatably connected to the bearing seats 404 in the two fixed base blocks 401;

[0036] The fixed base block 401 corresponds to the position of the lower roller 3 and is used as a carrier for installing the lower roller 3. The movable base block 402 corresponds to the upper roller 2, assists in installing the upper roller 2, and is used as a mounting carrier for the upper roller 2. In conjunction with the setting of the bearing seat 404, the upper roller 2 and the lower roller 3 are kept rotatable.

[0037] Limiting grooves 405 are provided on two opposite inner walls of the installation frame 4, and sliding bars 4021 are fixed on both sides of the movable base block 402, and the sliding bars 4021 are slidably arranged in the limiting grooves 405, and the bottom end of the fixed base block 401 is fixed to the top end of the glue groove 1; the upper end of the movable base block 402 is rotatably connected to a screw rod 403, and the upper thread of the screw rod 403 passes through the top of the installation frame 4 and extends out;

[0038] By rotating the screw rod 403, the height of the screw rod 403 in the installation frame 4 can be adjusted, thereby changing the height position of the movable base block 402. The movable base block 402 slides and engages in the limit groove 405 through the slide bar 4021, so that the movable base block 402 can only be raised and lowered but cannot be rotated.

[0039] In addition to the position of the mounting frame 4, a guard strip 101 is fixed to the top surface of the glue groove 1, and the upper end of the guard strip 101 is on the same horizontal plane as the central axis of the lower roller 3; the setting of the guard strip 101 can appropriately increase the height of the top of the glue groove 1 to prevent the glue in the glue groove 1 from overflowing.

[0040] An external bearing 501 is arranged between the end of the upper roller 2 and the rubber inlet pipe 5, and the outer ring of the external bearing 501 is fixed to the end of the upper roller 2, and the inner ring of the external bearing 501 is fixed to the outer wall of the rubber inlet pipe 5; this ensures that when the upper roller 2 rotates, the rubber inlet pipe 5 will not rotate therewith, and no mutual influence will occur.

[0041] The upper roller 2 has a cavity inside and both ends are connected. The inner cavity of the upper roller 2 is connected to the glue inlet pipe 5, and the end of the soft bristles 201 close to the upper roller 2 extends into the inner cavity of the upper roller 2; the glue liquid in the upper roller 2 can penetrate into the soft bristles 201 and be discharged for use in brushing glue.

[0042] The middle outer circumference of the lower roller 3 is provided with a threaded segment, and the threaded ring block 301 is screwed onto the threaded segment on the outer circumference of the lower roller 3; the relative threaded connection is achieved, and the corresponding quantity and position can be changed, which is convenient for brushing glue on the honeycomb paper core.

[0043] The specific working principle of the utility model is as follows: first, a certain amount of glue is stored in the glue tank 1 so that the hard brush bristles 3011 on the outer periphery of the lower roller 3 can be dipped into it. Then, according to the thickness of the honeycomb paper core to be glued, the distance between the upper roller 2 and the lower roller 3 is adjusted, and the screw 403 is rotated to make it rise and fall in the installation frame 4, so that the movable base block 402 slides up and down along the installation frame 4. The movable base block 402 is restricted by the slider and will not rotate, thereby changing the height position of the upper roller 2. When the lower roller 3 rotates, the hard bristles 3011 on the outside of the threaded ring block 301 screwed on its outer circumference will dip into the glue in the glue groove 1 and then coat it on the lower surface of the honeycomb paper core, while the upper roller 2 injects glue into the inner cavity of the upper roller 2 through the glue inlet pipe 5. As the upper roller 2 rotates, the soft bristles 201 are slowly soaked, so that the surface of the soft bristles 201 is stained with glue, and then rolled on the upper surface of the honeycomb paper core. In this way, when the honeycomb paper core passes between the upper roller 2 and the lower roller 3, the gluing process is quickly completed.
