DETAILED DESCRIPTION

[0027] In the prior art, glue is usually concentrated and transported to the middle part of the upper glue roller. When the upper glue roller rotates, the glue moves to the two ends of the upper glue roller. When the glue in the middle part of the upper glue roller becomes less and less due to smearing, the glue flowing into the two ends of the upper glue roller also becomes less and less, so that the glue at the two ends of the upper glue roller forms a film, which is not convenient to clean and affects the gluing quality of the packaging paper box. Therefore, after research, a circulating glue supply mechanism with overflow and anti-filming is provided. When in use, the area where the glue flows out is expanded by opening a glue outlet hole on the upper glue tube and adding an extended glue outlet tube, so that the glue can be distributed to various parts of the glue roller, promoting the uniform distribution of the glue, thereby preventing the glue from forming a film at the two ends of the glue roller, thereby solving the above-mentioned defects.

[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Please refer to Figure 1-Figure 5 The embodiment of the utility model provides a circulating glue supply mechanism for preventing overflow and conjunctiva, including a feed conveyor belt 1, one end of the feed conveyor belt 1 on one side of the feeding mechanism 2 is rotatably provided with a conveying roller 4 and a glue coating roller 41 arranged up and down, and one side of the glue coating roller 41 is rotatably provided with a rotating roller 42.

[0030] Among them, the conveying roller 4 is located on the lower side, and the glue coating roller 41 is located on the upper side. The packaging paper box passes between the two and is placed with the glued side facing up. The rotating shaft of the conveying roller 4 is connected to the gear 2 45, the rotating shaft of the glue coating roller 41 is connected to the gear 1 44, and the rotating shaft of the gear 2 45 is connected to the output shaft of the motor. The motor causes the gear 2 45 to rotate, and the meshing of the gear 1 44 and the gear 2 45 makes the gear 1 44 follow the rotation, so as to realize the common rotation of the glue coating roller 41 and the conveying roller 4, and the rotation of the roller 42 is also driven by the motor.

[0031] A detachable upper glue tube 46 is provided on the feed conveyor belt 1 located on the upper side of the rotating roller 42. The upper glue tube 46 is fixed by screws. A glue outlet head 47 is fixed on the upper glue tube 46. An extended glue outlet tube 48 is fixed on one side of the upper glue tube 46. The glue outlet of the extended glue outlet tube 48 is connected with the glue outlet hole 461 opened on the upper glue tube 46 through a pipeline. The glue is evenly distributed at various positions of the glue coating roller 41 through the glue outlet hole 461, the glue outlet head 47 and the extended glue outlet tube 48, which solves the problem of the original glue in the middle of the glue coating roller 41 and effectively prevents the glue from forming a film at both ends of the glue coating roller 41.

[0032] Since the positions of the glue outlet hole 461 and the glue outlet head 47 correspond to the connection between the rotating roller 42 and the glue coating roller 41 , the glue can be transported to the glue coating roller 41 .

[0033] Furthermore, the glue in the glue outlet head 47 and the extended glue outlet pipe 48 is transported by a glue pump 49. The glue inlet of the glue pump 49 is connected to the glue outlet of the glue cylinder 5 through a pipeline. The glue pump 49 continuously transports the glue in the glue cylinder 5 to between the glue coating roller 41 and the rotating roller 42. As the glue coating roller 41 rotates, the glue is spread all over the glue coating roller 41.

[0034] Furthermore, limit blocks 43 are provided on the upper sides of both ends of the rotating roller 42 and the glue coating roller 41, and the lower sides of the limit blocks 43 are in contact with the rotating roller 42 and the glue coating roller 41 without affecting the rotation of the two, so as to prevent the glue from overflowing.

[0035] In addition, a drive roller 7 is rotatably arranged on the feed conveyor belt 1 on the feed end side of the conveyor roller 4. The drive roller 7 is driven by a motor. A fixed rod 71 is arranged on the upper side of the drive roller 7. A roller 72 is rotatably arranged on the fixed rod 71. The roller 72 is used to press the packaging carton entering the glue coating to prevent the packaging carton from being displaced.

[0036] Furthermore, a connecting rod 6 is provided on the feed conveyor belt 1 on one side of the discharge end of the glue coating roller 41, and a pair of scrapers 61 are slidably provided on the connecting rod 6, and the lower end of the scraper 61 is in contact with the glue coating roller 41, and the glue coating roller 41 is fixed by bolts 62, and the scraper 61 is used to prevent the glued packaging box from sticking to the glue coating roller 41.

[0037] In order to understand the steps of the packaging carton entering the lower side of the glue coating roller 41, a feeding mechanism 2 is installed at one end of the feed conveyor belt 1, and the specific steps of the feeding mechanism 2 are disclosed. The feeding mechanism 2 includes a mounting plate 21 located on one side of the feed conveyor belt 1, and a slide groove 22 is opened on the mounting plate 21. A movable plate 24 is slidably arranged in the slide groove 22. A cylinder 23 is installed on one side of the slide groove 22, and the piston end of the cylinder 23 is connected to the movable plate 24. The cylinder 23 can cause the movable plate 24 to move back and forth in the slide groove 22 to transport materials.

[0038] At the same time, cylinder 241 is installed on the lower side of the movable plate 24, the piston end of cylinder 241 is connected to the fixing part 28, one side of the movable plate 24 is connected to the exhaust pipe 25, the air outlet of the exhaust pipe 25 is connected to the air inlet of the vacuum pump 26, the air inlet of the exhaust pipe 25 is connected to the air outlet of the suction cup 29 fixed on the fixing part 28 through the air pipe 27, cylinder 241 can move the suction cup 29 up and down, cooperate with the action of cylinder 1 23 to complete the feeding, and when the suction cup 29 descends, the vacuum pump 26 forms a vacuum inside the suction cup 29 to adsorb the material, thereby achieving the purpose of fixing the material.

[0039] After the packaging paper box is glued, it is conveyed to the discharge conveyor belt 3 provided at one end of the discharge port of the glue coating roller 41.

[0040] In summary, the working principle of the anti-overflow and anti-conjunctiva circulating glue supply mechanism of the embodiment of the utility model is: the glue pump 49 sucks the glue in the glue tube 5 into the glue outlet head 47 and the extended glue outlet pipe 48, and the glue flows into the space between the glue coating roller 41 and the rotating roller 42 through the extended glue outlet pipe 48, the glue outlet hole 461 and the glue outlet head 47. As the glue coating roller 41 rotates, the glue covers various positions of the glue coating roller 41, and the glue is limited by the limit block 43.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
