[0002] Paper tubes are hollow, tubular paper products, typically made from multiple layers of cardboard or kraft paper rolled together and processed through bonding and drying. They are lightweight, high-strength, moisture-proof, and environmentally friendly, and are widely used in packaging, transportation, construction, agriculture, and other fields. For example, in the packaging industry, paper tubes are often used as cushioning materials to protect goods from damage; in agriculture, they are used as supporting structures for plant growth, helping plants maintain upright growth.

[0003] In existing technologies, paper tube processing requires the use of paper tube winding machines. To ensure a continuous supply of raw materials such as paper, paper tube winding machines typically employ a feeding device. Before the paper enters the forming mold, it undergoes a gluing process, where an appropriate amount of adhesive is evenly applied to the paper so that subsequent layers can be firmly bonded together. However, in existing paper tube winding machines, the feeding device and the gluing process are not synchronized, and the gluing process is unstable and prone to misalignment. Utility Model Content

[0010] Furthermore, the adhesive coating structure includes a rotating hollow tube, which is fixedly connected to the interior of the fourth gear.

The surface of the rotating hollow tube is movably connected to the interior of the support frame. The surface of the rotating hollow tube has several through holes that are evenly distributed.

The threaded end of the first screw passes through the first limiting ring and extends to the surface of the rotating hollow tube.

[0011] Furthermore, a movable plug is movably connected inside the rotating hollow tube, a guide rod is fixedly connected to the rear side of the movable plug, a movable sleeve is sleeved on the rear side of the surface of the rotating hollow tube, the rear side of the guide rod penetrates the rotating hollow tube and is fixedly connected to the inner wall of the movable sleeve, and the front side of the movable sleeve is fixedly connected to the rear side of the second limiting ring.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a base, support frame, geared motor, sleeve, compaction structure, transmission structure, central shaft, unloading roll, conveying structure, and gluing structure, achieves automated material feeding by setting up a base, support frame, geared motor, sleeve, compaction structure, transmission structure, central shaft, unloading roll, and gluing structure. The geared motor drives the sleeve to rotate, which in turn drives the central shaft and unloading roll to rotate through the transmission structure, thereby achieving automated material feeding and improving work efficiency. The compaction structure design can effectively compact the material and ensure processing quality. At the same time, the fixed connection between the compaction structure and the base ensures the stability of the structure. The conveying structure delivers the adhesive to the gluing structure, and the gluing structure then evenly applies the adhesive to the material, improving the bonding effect and ensuring product quality. The reasonable design of each component achieves tight connection, which not only saves space but also improves the overall stability and durability of the equipment.

[0016] 2. This utility model, by setting up a compaction structure, can significantly improve the pressing effect of the paper tube. The pressure rollers movably connected on the movable frame, used in conjunction with the sleeve, can ensure that the paper tube will not loosen or shift during processing or transportation, thus guaranteeing the stability and integrity of the paper tube. The uniform distribution of the guide columns and the setting of the tension springs not only enhance the stability of the movable frame, but also enable the pressure rollers to apply pressure more evenly and smoothly when pressing the paper tube, avoiding damage to the paper tube caused by uneven pressure. The elastic effect of the tension springs can also be adaptively adjusted according to the size of the paper tube.

[0017] 3. This utility model, through the setting of a transmission structure, can achieve stable power transmission and conversion. The first gear is fixedly connected to the surface of the sleeve to ensure effective power input. The meshing of the first chain with the first and second gears realizes the first transmission and direction of power. The fixed connection of the second gear with the central shaft allows the power to continue to be transmitted to the central shaft. The central shaft passes through the support frame and is movably connected to ensure smooth and stable transmission. The fixed connection of the third gear on the front side of the central shaft, and its meshing with the second chain and the fourth gear, further realizes the second transmission and direction of power, ultimately driving the adhesive coating structure to work. This can effectively reduce energy loss and improve the overall operational stability and working efficiency of the equipment.

[0018] 4. This utility model, by setting up an adhesive coating structure, allows the rotating hollow tube to rotate flexibly within the support frame. At the same time, the position is limited by the first limiting ring on the front side and the second limiting ring on the rear side, ensuring the stability of the rotating hollow tube during rotation. The first limiting ring is fastened to the rotating hollow tube by the first screw, which facilitates installation, disassembly and adjustment, and improves the flexibility of the structure. The uniformly distributed through holes on the surface of the rotating hollow tube can easily apply adhesive to the roll material through the through holes.

[0019] 5. This utility model, by setting up a movable plug, a guide rod, and a movable sleeve, allows the movable plug to move flexibly inside the rotating hollow tube. At the same time, the guide rod is fixedly connected to the movable plug and passes through the rotating hollow tube to the outside and is fixed to the inner wall of the movable sleeve. This allows the displacement of the movable plug to drive the synchronous movement of the movable sleeve, ensuring the linkage of the structure. The fixed connection between the second limiting ring and the front side of the movable sleeve further enhances the stability and reliability of the structure, making the entire device more stable during operation.

[0020] 6. This utility model effectively enhances the sealing performance and prevents leakage by setting a sealing strip. The second screw set at the top of the movable sleeve has its threaded end that can penetrate the movable sleeve and be fastened to the surface of the rotating hollow tube, which improves the stability of the structure and facilitates the adjustment of the position of the movable plug. It also facilitates the application of adhesive to paper tube materials of different widths.

[0021] 7. This utility model, through the setting of a conveying structure, can achieve stable conveying and flexible mixing of adhesive. The design of the placement chamber facilitates the storage and initial holding of adhesive. The fixed connection between the bottom and the base ensures the stability of the structure. Adhesive can be easily added through the feed port. The connection between the first conduit and the water pump, and the fixed connection between the water pump output end and the second conduit, form an effective adhesive conveying channel, which can achieve continuous and uniform conveying of adhesive. The end of the second conduit away from the water pump extends into the interior of the rotating hollow tube and is movablely connected to the interior of the rotating hollow tube through the sealing sleeve, ensuring the continuity of adhesive conveying. Thus, the adhesive is evenly coated on the surface of the paper tube material through the through holes on the rotating hollow tube. Attached Figure Description

[0041] Working principle: During operation, the paper tube material is first placed at the feed roll 6 position, and the material is drawn out and wound between the sleeve 4 and the pressure roller 8. The pressure roller 8, under the action of the tension spring 11, presses the paper tube tightly to ensure that the paper tube will not loosen or shift during processing or transportation. The reduction motor 3 starts, and its output end drives the sleeve 4 to rotate. The first gear 12 on the surface of the sleeve 4 rotates accordingly, and transmits power to the second gear 14 through the first chain 13. The second gear 14 is fixedly connected to the central shaft 5, and the central shaft 5 also begins to rotate. The third gear 15 on the surface of the central shaft 5 further transmits power to the fourth gear 17 through the second chain 16. The fourth gear 17 is fixedly connected to the rotating hollow tube 18 inside the adhesive coating structure, thereby driving the rotating hollow tube 18 to rotate. The through holes 19 on the surface of the rotating hollow tube 18 evenly apply adhesive to the paper tube material. The adhesive is supplied by a conveying structure. Specifically, the adhesive is placed in the placement chamber 28. Through the action of the water pump 30, the adhesive is drawn into the water pump 30 through the first conduit 29, and then delivered from the output end of the water pump 30 to the interior of the rotating hollow tube 18 through the second conduit 31. The movable plug 23 inside the rotating hollow tube 18 can move flexibly under the action of the guide rod 24 and the movable sleeve 25 to adapt to paper tube materials of different widths. At the same time, the sealing strip 26 effectively prevents the adhesive from leaking. During the glue application process, the front and rear sides of the rotating hollow tube 18 are respectively limited by the first limiting ring 20 and the second limiting ring 22, ensuring the stability of the rotating hollow tube 18 during rotation. The displacement of the movable plug 23 can drive the synchronous movement of the movable sleeve 25, ensuring the linkage of the structure and making the entire device more stable during operation.
