[0002] Paper straws, as the name suggests, are made of paper and are biodegradable. With increasing environmental protection requirements, paper straws are being promoted for their good biodegradability. During the production of paper straws, a gluing device is required to apply glue to the surface of the paper. The stickiness of the glue is used to make the rolled paper into paper straws.

[0003] The utility model patent with the authorization publication number CN213255391U discloses a gluing device for a paper straw machine. When in use, the gluing device is provided with baffles on the coating roller to limit the passage of the paper tape. A plurality of uniform glue overflow holes are provided on the outer wall of the coating roller between the baffles. Glue discharged through the glue overflow holes is coated on the paper tape to complete the coating. However, the glue overflow holes are blocked at the contact point between the paper tape and the coating roller, resulting in glue being discharged only through the unblocked glue overflow holes. As a result, the glue is not directly coated on the paper tape, and the glue discharged from the glue overflow holes is concentrated in the middle of the paper tape, seriously affecting the uniformity of the glue coating at the edge of the paper tape, and thus affecting the production quality of paper straws.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example: Reference Figure 1-5The paper straw machine gluing device shown includes a support frame 1, a first motor 2 is provided on the front side of the support frame 1, a liquid collecting tank 3 is provided at the bottom inside the support frame 1, and the front and rear inner walls of the support frame 1 are rotatably connected with a first roller 4, a glue roller 5, an auxiliary roller 6 and a second roller 7. The auxiliary roller 6 is located between the first roller 4 and the second roller 7, and the auxiliary roller 6 is located directly below the glue roller 5. The glue roller 5 is driven by the first motor 2, and a glue supply assembly and a limiting assembly are provided on the support frame 1. The glue supply assembly is used to drip glue onto the glue roller 5, and the limiting assembly is used to limit the paper tape on the first roller 4. End plates 8 are fixed on the front and rear inner walls of the support frame 1, and a spreading plate 9 is fixed between the two end plates 8. The cross-section of the spreading plate 9 is an "L"-shaped structure, and the spreading plate 9 is used to spread the glue on the glue roller 5. Two liquid guide tubes 10 are fixed through the bottom of the spreading plate 9, and both liquid guide tubes 10 are located directly above the liquid collecting tank 3.

[0024] The glue dripping from the glue supply assembly to the surface of the glue coating roller 5 is spread out by using the spreading plate 9, so that the glue coating roller 5 driven by the first motor 2 can transfer the glue to the paper tape passing through the auxiliary roller 6 when rotating, thereby completing the gluing process of the paper tape and making the gluing of the paper tape more uniform. The excess glue on the glue coating roller 5 will be scraped off by the spreading plate 9, flow into the interior of the liquid collecting box 3 along the two liquid guide tubes 10 and be collected, thereby avoiding waste of glue.

[0025] Among them, the glue supply component includes a glue storage cylinder 11 and a glue pump 12, and the glue storage cylinder 11 and the glue pump 12 are both arranged on the support frame 1. The glue inlet of the glue pump 12 is fixedly connected to a glue delivery pipe 13, and the top of the glue delivery pipe 13 is connected to the bottom of the glue storage cylinder 11. The glue outlet of the glue pump 12 is fixedly connected to a glue guide pipe 14, and the glue guide pipe 14 is located directly above the glue coating roller 5. A support plate 15 is fixed to the top of the glue storage cylinder 11, and the lower surface of the support plate 15 is rotatably connected to a transmission rod 16 through a bearing. A spiral auger 17 is fixed to the bottom end of the transmission rod 16, and the bottom of the spiral auger 17 extends to the inside of the glue delivery pipe 13. A second motor 18 is provided on the top of the support plate 15, and the transmission rod 16 is driven by the second motor 18.

[0026] The second motor 18 is used to drive the spiral auger 17 to rotate, so that the spiral auger 17 transports the glue in the glue storage cylinder 11 to the glue delivery pipe 13. In this way, the glue pump 12 can better pump the glue into the glue guide pipe 14, so that the glue drips along the glue guide pipe 14 onto the glue coating roller 5, so as to facilitate the gluing process of the paper tape.

[0027] Among them, the limiting assembly includes a fixed plate 19, which is arranged on the support frame 1, and a reserved groove 20 is opened at the bottom of the fixed plate 19. The front and rear inner walls of the reserved groove 20 are rotatably connected to a screw rod 21 through a bearing. A carrier block 22 is threadedly connected to the screw rod 21, and the carrier block 22 slides with the inner wall of the reserved groove 20. A limiting ring 23 is fixed to the bottom of the carrier block 22, and the two limiting rings 23 are slidably sleeved on the outside of the first roller shaft 4. The other end of the screw rod 21 is fixed with a first bevel gear 24, and a third motor 25 is provided on the top of the fixed plate 19. The output shaft end of the third motor 25 is fixed with a second bevel gear 26, and the second bevel gear 26 is located between the two first bevel gears 24, and the second bevel gear 26 and the two first bevel gears 24 are meshed with each other.

[0028] The third motor 25 is used to drive the second bevel gear 26 to rotate. With the help of the second bevel gear 26 and the two first bevel gears 24 engaging with each other, the two screw rods 21 can be pulled to rotate, so that the two screw rods 21 can adjust the distance between the two limiting rings 23 in a screw rod transmission manner, so that the first roller 4 can limit the paper tape with the help of the two limiting rings 23, which is more conducive to the subsequent gluing process of the paper tape.

[0029] This utility works as follows:

[0030] When in use, the paper tape is sequentially wound around the first roller 4, the auxiliary roller 6, and the second roller 7 and then fed into the paper straw machine for the production of paper straws. The paper tape passes between the glue coating roller 5 and the auxiliary roller 6. As the paper tape is wound, the second motor 18 is controlled to drive the spiral auger 17 to rotate, so that the spiral auger 17 transports the glue in the glue storage cylinder 11 to the glue delivery pipe 13 in an orderly manner, and the glue pump 12 is started to conduct the glue in the glue delivery pipe 13 to the guide hose 14, so that the glue flows along the guide hose 1 4 drips onto the glue coating roller 5, and the first motor 2 drives the glue coating roller 5 to rotate. The spreading plate 9 can spread the glue dripping from the glue coating roller 5 so that the glue is evenly coated on the outer wall of the glue coating roller 5. The excess glue is collected in the spreading plate 9 and can flow into the interior of the collecting tank 3 along the liquid guide tube 10 to be collected. When the paper strip passing between the glue coating roller 5 and the auxiliary roller 6 contacts the glue coating roller 5, the glue on the glue coating roller 5 can be transferred to the paper strip, completing the uniform gluing process on the paper strip;

[0031] During the paper tape conveying process, the third motor 25 can be controlled to drive the second bevel gear 26 to rotate. With the help of the second bevel gear 26 and the two first bevel gears 24 engaging with each other, the two screw rods 21 can be pulled to rotate, so that the two screw rods 21 can adjust the distance between the two limit rings 23 in a screw rod transmission manner. In this way, the paper tape passing through the first roller 4 is limited, and the gluing process can be completed more accurately.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
