[0002] Paper tube is a tubular object made of paper, and gluing is usually needed to enhance structural stability or sealing. Currently, contact and non-contact gluing methods are mainly used. The contact method directly contacts the inner wall of the paper tube with the gluing part to transfer glue, and relies on mechanical fitting to achieve coating, which is suitable for high-viscosity glue.

[0074] The stable part is provided on the outside of glue injection pipe 4 and one side of sleeve one 6 to ensure the stability of glue injection;

[0075] The stabilizing part includes an extension member and a locking member. The extension member is located on the outside of the glue spray tube 4 and is connected to the locking member. The locking member is located on one side of the sleeve 6.

[0079] The collection section includes a cleaning component and a dispensing component. The cleaning component is located outside the unblocking component and is connected to the dispensing component. The dispensing component is located on one side of the moisturizing component.

[0080] Specifically, the spray tube 4 passes through the stabilizing frame 5, sleeve 6, sleeve 9, and mounting ring 10; the spray tube 4 is fixedly connected to sleeve 9; the spray tube 4 passes through sleeve 6, sleeve 9, and mounting ring 10; the inner wall of the base 1 has a groove adapted to the slider 2; the screw 3 is threadedly driven to the slider 2, and one end of the screw 3 is equipped with a motor and connected to the motor output end; the stabilizing frame 5 supports the spray tube 4, which is beneficial for the balance of spraying during travel; one end of the spray tube 4 is connected to the pump body; the interior of the central shaft 11 is a cavity, which communicates with the spray hole of the rotating nozzle 12; the central shaft 11 can rotate in conjunction with the pump body or air pressure, which is to link the rotation of the rotating nozzle 12 to form a uniform spray at multiple angles; this equipment is suitable for low to medium viscosity adhesives;

[0081] In practical application, the operator first powers on the motor to drive the screw 3. The screw 3, through its threaded action, pushes the slider 2 along the inner groove of the base 1 towards the inner wall of the paper tube. The slider 2 drives the stabilizing frame 5 to move, and the stabilizing frame 5 moves together with the spray tube 4.

Then, by adding an appropriate amount of glue from one side of the spray tube 4, and with the power source of the pump providing pressure, the glue stored inside the spray tube 4 is delivered to the rotating nozzle 12 at the top. The glue is then evenly applied from the spray hole using pressure, centrifugal force, or atomization, thereby completing the spraying of the inner wall of the paper tube and improving the structural stability and sealing of the inner wall of the paper tube.

[0082] like Figures 1 to 3 As shown, the extension member includes:

[0083] Sleeve 6 is slidably positioned on the outside of the glue spray tube 4;

[0089] The installation ring 10 is arranged outside the glue spraying pipe 4.

[0090] The elastic plug 32 is arranged at one end of the thin rod 8 close to the guide plate 7.

[0091] Specifically, a plurality of limiting grooves matched with the elastic plug 32 are arranged inside the guide plate 7; the sleeve two 9 can support the height of the guide plate 7, facilitating timely insertion of the guide plate into the inner wall of the paper cylinder; a sliding groove is arranged at one side of the guide plate 7 in contact with the thin rod 8; a roller is arranged at the top end of the guide plate 7 to prevent scratches during movement.

[0092] In actual application, since the inner diameters of the paper cylinders are different, the inner wall of the paper cylinder needs to be supported before spraying the glue solution to prevent imbalance of the paper cylinder and improve the universality of the glue spraying pipe, the sleeve one 6 is first arranged outside the glue spraying pipe 4, the guide plate 7 is adjusted upwards according to the inner diameter of the paper cylinder, and then the height of the thin rod 8 is adjusted, after the two are adjusted, the thin rod 8 moves along the sliding groove below the guide plate 7, when the supporting height is appropriate to the height of the inner wall of the paper cylinder, the thin rod 8 drives the elastic plug 32 to slide, the elastic plug 32 slides along the side of the guide plate 7, and gradually falls into the limiting groove when encountering the limiting groove, thereby completing the internal fixation of the guide plate 7.

[0093] As shown in Figures 3 to 4 The dredging part comprises:

[0094] The guide rod 14 is arranged at one side of the installation ring 10.

[0095] The arc-shaped rod 15 is arranged at one end of the guide rod 14.

[0096] The dredging rod 16 is arranged to penetrate the inside of the arc-shaped rod 15.

[0097] The ring body 13 is arranged at one end of the guide rod 14 and connected with the arc-shaped rod 15.

[0098] The sub-packaging cover 17 is arranged outside the dredging rod 16.

[0099] The sub-rod 18 is arranged at one side of the sub-packaging cover 17.

[0100] Pulling plate 19, arranged at the bottom end of the strip 18;

[0101] Stretching spring 20, arranged inside the arc-shaped rod 15;

[0102] Pressure block 21, arranged below the stretching spring 20, and fixedly connected with the arc-shaped rod 15.

[0103] Specifically, the guide strip 14 is used to support the ring body 13, prevent the arc-shaped rod 15 from swinging, and avoid affecting the dredging work; the installation of the setting ring 10 and the ring body 13 is used to balance the arc-shaped rod 15, prevent the arc-shaped rod 15 from drooping at one end due to gravity after long-term use, and avoid blocking the glue spraying; the dredging strip 16 is convenient for resetting the arc-shaped rod 15, and the arc-shaped rod 15 is internally provided with a condition adapted to the dredging strip 16;

[0104] In the application process of the embodiment, the spray hole of the rotating nozzle 12 is often in contact with air, contains impurities or solid residues inside, and needs to be treated. When the glue spraying solution impacts upward, it will contact the center position of the pulling plate 19, the pulling plate 19 moves upward and deforms, stays on the lower surface of the arc-shaped rod 15 along with the movement of the dredging strip 16, and scrapes the inner wall of the paper cylinder along with the upward movement of the pulling plate 19, pushes out the blocked impurities from the spray hole, has the function of dredging, and is convenient for the next glue spraying use;

[0105] When the pulling plate 19 is deformed by being impacted, the center position of the pulling plate 19 will extrude the dredging strip 16 to move upward, the stretching spring 20 is gradually compressed at the pressure block 21, the dredging strip 16 moves to drive the sub-pack cover 17 to move, the sub-pack cover 17 moves upward, the pulling plate 19 rotates when pulling the strip 18, the strip 18 approaches the dredging strip 16 to be in a contracted state, through the cooperation of the strip 18, the sub-pack cover 17 and the dredging strip 16, the center of the pulling plate 19 protrudes upward and is relatively sharp, the pulling plate 19 as a whole is deformed from a flat state to a conical state, and is contracted at one end below the arc-shaped rod 15, and after being contracted below the arc-shaped rod 15, the pulling plate 19 is separated from the glue spraying range of the rotating nozzle 12, so as to avoid interference;

[0106] As shown in Figures 7 to 8 , the moisturizing member includes:

[0107] Inclined plate 22, arranged outside the arc-shaped rod 15, and connected with one end of the glue spraying pipe 4;

[0108] Rubber capsule 24, arranged inside the inclined plate 22;

[0109] Shunt pipe 25, fixedly installed below the rubber capsule 24;

[0110] Filling head 23, fixedly installed above the rubber capsule 24.

[0111] Specifically, the setting of the inclined plate 22 facilitates the rubber capsule 24 to flow down faster when dripping liquid, preventing residual dripping; the rubber capsule 24 contains alcohol, which completes the moisturizing of the spray holes of the rotary spray head 12, facilitating the washing of the rubber tube; the shunt pipe 25 facilitates the timely discharge of alcohol liquid; the filling head 23 facilitates timely filling; the rubber capsule 24 is irregularly shaped, and the rubber capsule 24 extends beside the arc-shaped rod 15 through the inner wall of the inclined plate 22;

[0112] In actual application, although the blocked part is dredged and cleaned, dry cleaning around the spray hole is prone to occur in hot weather, which is very unfavorable for subsequent uniform glue spraying, so it is necessary to moisten it. When this happens, twist the filling head 23, add alcohol or special cleaning agent solution into it, and when the dredging strip 16 moves upward, the dredging strip 16 will be extruded by the rubber capsule 24, and the rubber capsule 24 will be extruded to release the solution, which will be dripped into the spray hole through the shunt pipe 25, ensuring the moisture and cleanliness of the spray hole.

[0113] As shown in Figures 9 to 10 , the cleaning member includes:

[0114] The cleaning cylinder 28 is arranged below the inclined plate 22.

[0115] The coupling ring 29 is arranged on the inner wall of the cleaning cylinder 28.

[0116] The driving block 30 is arranged outside the coupling ring 29.

[0117] The cotton wiping plate 31 is fixedly installed on the inner wall of the driving block 30.

[0118] The glue distribution member includes:

[0119] The glue discharge groove 34 is arranged in the inner cavity of the inclined guide plate 35.

[0120] The storage rack 26 is arranged below the inclined plate 22.

[0121] The diameter of the through slot 27 is smaller than that of the cleaning cylinder 28.

[0122] The inclined guide plate 35 is arranged above the storage rack 26.

[0123] The through slot 27 is arranged on one side of the storage rack 26.

[0124] Specifically, the cleaning cylinder 28 is used to clean the impacted part outside the pulling plate 19, preventing residual from causing harm to personnel; the through slot 27 facilitates the passage of the deformed pulling plate 19; the cotton wiping plate 31 is used to wipe the dust outside the pulling plate 19, and the glue discharge groove 34 facilitates the guidance of the scraped blockage impurities.

[0125] In actual implementation, pulling the plate 19 upward will enter the inside of the wall cleaning cylinder 28, and the cotton wiping plate 31 wipes the outside of the pulling plate 19, thereby cleaning the residual glue solution outside the pulling plate 19, and improving the cleanliness;

[0126] The connecting ring 29 is used to connect the plurality of driving blocks 30 together, so that the plurality of driving blocks 30 can wipe the plurality of outer surfaces of the pulling plate 19. When the pulling plate 19 contacts the cotton wiping plate 31, the cotton wiping plate 31 wipes the strip to swing, and the driving block 30 and the connecting ring 29 are used to stabilize and avoid entanglement. The blocked objects after wiping and the residual glue generated by flushing gradually fall downward and enter the downward recessed glue discharge groove 34. Through the guidance of the glue discharge groove 34, the glue is finally recycled in the storage rack 26, thereby ensuring the quality and effect of processing.

[0127] Working principle:

[0128] When the device is started, the worker starts the motor connected to one end of the screw rod 3 by power-on. The motor drives the screw rod 3 to rotate. Since the screw rod 3 is in threaded transmission with the sliding block 2, and the sliding block 2 is slidingly installed in the sliding groove matched with the inner wall of the base 1, the rotation of the screw rod 3 will drive the sliding block 2 to move along the sliding groove on the inner side of the base 1 towards the inner wall of the paper cylinder. The stable frame 5 fixedly installed above the sliding block 2 moves together with the sliding block 2, thereby driving the glue injection pipe 4 penetrating through the stable frame 5 to move, and the glue injection pipe 4 drives the middle shaft 11 and the rotating nozzle 12 at the top end to enter the inner wall of the paper cylinder, thereby completing the position positioning before glue application.

[0129] The outer pump body pressurizes the glue solution into the cavity of the middle shaft 11 through the glue injection pipe 4, and the glue solution reaches the rotating nozzle 12. The middle shaft 11 rotates under the action of pressure or centrifugal force, thereby driving the rotating nozzle 12 to spray at multiple angles, and forming a uniform coating.

[0130] In order to adapt to paper cylinders with different inner diameters and ensure the stability of glue injection, the stable part needs to be adjusted first. The sleeve one 6, the swing block 33, the guide plate 7, the thin branch 8, the sleeve two 9, the placement ring 10, and the elastic latch 32 work together:

[0131] The sleeve one 6 is sleeved outside the glue injection pipe 4. The worker adjusts the height of the guide plate 7 according to the inner diameter of the paper cylinder. The roller at the top end of the guide plate 7 can prevent scratches on the inner wall of the paper cylinder during movement.

[0132] At the same time, the height of the thin branch 8 is adjusted. The thin branch 8 moves along the slide under the guide plate 7. When the support height is matched with the height of the inner wall of the paper cylinder, the thin branch 8 drives the elastic latch 32 to slide. The elastic latch 32 slides along the side of the guide plate 7 and falls into the pre-set limiting groove, thereby completing the fixation of the guide plate 7.

[0133] The sleeve two 9 supports the height of the guide plate 7, and the stable frame 5 supports the whole glue injection pipe 4, thereby jointly ensuring the balance and stability during the glue injection process.

[0134] The one end of the glue injection pipe 4 is connected with the pump body. When the rotating nozzle 12 enters the inner wall of the paper tube, the pump body provides pressure to deliver the glue liquid in the glue injection pipe 4, which is suitable for low viscosity to medium viscosity glue, to the central shaft 11. The central shaft 11 is hollow inside and communicates with the spray hole of the rotating nozzle 12. The glue liquid is uniformly coated on the inner wall of the paper tube by the rotating nozzle 12, the central shaft 11, the pump body or air pressure, and the rotating nozzle 12 driven by the rotating nozzle 12.

[0135] In this process, the anti-blocking part works synchronously to avoid clogging of the spray hole and improve uniformity. The guide strip 14, the arc-shaped rod 15, the dredging strip 16, the ring body 13, the sub-pack cover 17, the sub-strip 18, the pulling plate 19, the stretching spring 20, the pressure block 21 and the inclined plate 22, the rubber capsule 24, the dredging strip 16, the rubber capsule 24, the alcohol solution is released through the shunt pipe 25 and dripped around the spray hole of the rotating nozzle 12, which prevents the glue liquid from drying and remaining. The shunt pipe 25 and the filling head 23 cooperate to prevent the glue liquid from impacting the pulling plate 19, which is deformed into a conical shape upward, pushing the dredging strip 16 upward and compressing the stretching spring 20. The dredging strip 16 is separated from the spray hole, and the sub-strip 18 is retracted with the sub-pack cover 17 to avoid interfering with the glue injection.

[0136] Before glue injection, the dredging strip 16 is inserted into the spray hole of the rotating nozzle 12 by default. When glue injection, the glue liquid impacts the center of the pulling plate 19 upward, driving the pulling plate 19 to move upward and deform.

[0137] The pulling plate 19 moves upward and scrapes the inner wall of the paper tube, pushing out the clogging impurities in the spray hole to achieve dredging. At the same time, the pulling plate 19 extrudes the dredging strip 16 to move upward, causing the stretching spring 20 to gradually compress at the pressure block 21.

[0138] The movement of the dredging strip 16 drives the sub-pack cover 17 to move, and the sub-pack cover 17 pulls the sub-strip 18 to rotate. The sub-strip 18 is retracted to the dredging strip 16 in a contracted state, causing the pulling plate 19 to deform from a flat shape to a conical shape, and finally retracted to below the arc-shaped rod 15, out of the glue injection range of the rotating nozzle 12, to avoid interfering with the glue injection.

[0139] At the same time, the inclined plate 22 on the outside of the arc-shaped rod 15 is provided with a rubber capsule 24, and the rubber capsule 24 is filled with alcohol or special cleaning agent. When the dredging strip 16 moves upward, the rubber capsule 24 is extruded, and the liquid in the rubber capsule 24 is dripped around the spray hole of the rotating nozzle 12 through the shunt pipe 25 to keep the spray hole wet and prevent the glue liquid from solidifying and clogging, further improving the uniformity of the spraying. In addition, the guide strip 14 supports the ring body 13, the setting ring 10 balances the arc-shaped rod 15 with the ring body 13, and avoids the arc-shaped rod 15 from being blocked by the glue injection due to gravity.

[0140] Through the cooperation of the clear wall cylinder 28, the coupling ring 29, the driving block 30, the cotton rubbing plate 31 structure and the glue discharge groove 34, the storage rack 26, the inclined guide plate 35, and the through slot 27, the residual glue on the dredging piece is collected:

[0141] Pull the plate 19 up into the clear wall cylinder 28, and the cotton rubbing plate 31 wipes the surface residual glue solution.

[0142] The driving block 30 and the coupling ring 29 ensure that the cotton rubbing plate 31 is in uniform contact, and the impurities fall into the storage rack 26 through the glue discharge groove 34. During the upward movement of the pulling plate 19, it will enter the inside of the clear wall cylinder 28. The driving block 30 on the inner wall of the clear wall cylinder 28 is connected through the coupling ring 29, which drives the cotton rubbing plate 31 to contact the outer side of the pulling plate 19. The cotton rubbing plate 31 swings to wipe off the residual glue solution on the outside of the pulling plate 19;

[0143] After the glue spraying is completed, the pump pressure is reduced, the tension spring 20 rebounds, and the dredging strip 16 reinserts into the spray hole to prevent blockage.

[0144] The pulling plate 19 returns to the flat state, and the rubber capsule 24 stops releasing alcohol;

[0145] The wiped off blockage and residual glue generated by flushing fall downward into the glue discharge groove 34 above the inclined guide plate 35. The glue solution residue after wiping is collected along the inclined guide plate 35 to the storage rack 26 through the through slot 27, facilitating centralized cleaning. Through the guiding action of the glue discharge groove 34, it finally flows into the storage rack 26. The diameter of the through slot 27 is smaller than that of the clear wall cylinder 28, which facilitates the passage of the pulling plate 19, realizes the recycling of residual glue, ensures the processing quality and equipment cleaning, and greatly reduces the blockage rate through the above anti-blocking technical scheme, which is suitable for low to medium viscosity glue.

[0146] In summary, through the coherent process of starting positioning, stable adjustment, glue spraying anti-blocking, and residual collection, the device efficiently completes the glue coating work on the inner wall of the paper tube, and significantly improves the structural stability and sealing performance of the inner wall of the paper tube.
