Description

Technical Field

[0001] This application relates to the field of paper drum production equipment technology, and more specifically, to an adhesive application device for paper drums. Background Technology

[0002] As a disposable packaging container, paper drums have a huge market demand. During their manufacturing process, to effectively enhance the drum's pressure resistance and improve brand recognition and influence, a fan-shaped panel with product details and brand logo is attached to the outside of the paper drum. Currently, the fan-shaped panel attachment process often relies on manual application of glue. Specifically, the paper drum is first placed on a cup mold, then the mold is turned on to rotate at a constant speed. At this time, workers use glue bottles and other tools to gradually approach the edge of the rotating paper drum, carefully applying glue around the rim. After application, the paper drum is automatically transferred to the next process for a tight bonding operation between the fan-shaped panel and the drum body, thus completing the fan-shaped panel attachment process.

[0003] However, when applying glue manually, it is difficult to ensure that the glue is evenly distributed along the edge of the paper container due to factors such as the worker's technique, pressure, and attention. Even slight hand tremors or inconsistent speed during application can result in uneven glue thickness. Thicker areas are prone to overflowing after the fan blades are bonded, affecting aesthetics and potentially sticking to other equipment or products; thinner areas, on the other hand, can cause the fan blades to not adhere firmly, leading to quality issues such as curling or detachment. Summary of the Invention

[0004] The purpose of this application is to provide an adhesive applicator for paper buckets, which can solve the technical problems of uneven distribution of adhesive at the edge of the paper bucket when manually applying adhesive during the process of pasting fan blades onto the paper bucket, uneven adhesive thickness caused by hand shaking or unstable speed during application, thick areas of adhesive overflowing after the fan blades are pasted, affecting aesthetics and other aspects, and thin areas of adhesive causing the fan blades to not be firmly pasted.

[0006] The adhesive application assembly includes a rotating shaft, an application turntable, a clamping member, and a locking member. The rotating shaft is rotatably mounted on the frame, and the lower end of the rotating shaft is connected to the output shaft of the drive motor.

The rotating shaft is provided with threads, and the locking member is provided with threaded holes that are adapted to the threads. The locking member is threadedly connected to the rotating shaft and the application turntable can be clamped against the support ring by the clamping member.

[0008] Furthermore, the rotating shaft is provided with a limiting protrusion, which is located on the upper part of the support ring. The through hole is provided with a limiting groove that matches the limiting protrusion. When the coating turntable and the clamping member are sleeved on the rotating shaft, the limiting protrusion is located in the limiting groove.

[0009] Furthermore, the top of the coating turntable is provided with a limiting ring that is adapted to the abutment, and the upper part of the abutment is provided with an annular protrusion, and an annular groove is formed between the annular protrusion and the limiting ring.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Specific implementation examples:

[0028] like Figure 1-3 As shown, this application provides a glue application device for paper buckets, including a frame 1, on which a glue application assembly 2 is rotatably mounted. A drive motor 3 is provided on the frame 1 to drive the glue application assembly 2 to rotate at a uniform speed. A glue supply assembly 4 is also provided on the frame 1 to supply glue to the glue application assembly 2. The glue application assembly 2 includes a rotating shaft 21, an application turntable 22, a clamping member 23, and a locking member 24. The rotating shaft 21 is rotatably mounted on the frame 1, and its lower end is connected to the output shaft of the drive motor 3. The clamping member 23 and the locking member 24 are connected to each other. The component 24 locks the coating turntable 22 onto the rotating shaft 21. Through the cooperation of the drive motor 3 and the glue coating component 2, the uniformity of the coating process is ensured. Compared with manual coating, which is affected by hand tremors and unstable speed, resulting in uneven glue distribution, this device can coat the glue on the edge of the paper bucket at a stable speed and with a uniform thickness. This not only improves the coating quality and avoids problems such as glue overflowing due to excessive thickness or poor adhesion due to excessive thinness, but also greatly improves work efficiency. More paper buckets can be processed per unit time, meeting the needs of large-scale production.

[0029] like Figure 2 and Figure 3 As shown, a support ring 5 is provided on the rotating shaft 21, and through holes 6 are provided in the middle of the coating turntable 22 and the clamping member 23. The coating turntable 22 and the clamping member 23 are sleeved on the rotating shaft 21 through the through holes 6. The rotating shaft 21 is provided with threads, and the locking member 24 is provided with threaded holes 7 that are adapted to the threads. The locking member 24 is threadedly connected to the rotating shaft 21 and can clamp the coating turntable 22 against the support ring 5 through the clamping member 23. The support ring 5 provides a stable support base for the coating turntable 22. When the coating turntable 22 is sleeved on the rotating shaft 21 and abuts against the support ring 5, it can effectively prevent the coating turntable 22 from radially shifting or shaking during high-speed rotation, ensuring that the glue coating trajectory is always accurate and consistent, so that the glue can be evenly and accurately applied to the edge of the paper container, greatly improving the bonding quality of the product. The use of threaded connection makes the assembly and disassembly of the coating turntable 22, the clamping member 23 and the rotating shaft 21 extremely simple.

[0030] like Figure 2 and Figure 3 As shown, a limiting protrusion 8 is provided on the rotating shaft 21. The limiting protrusion 8 is located on the upper part of the support ring 5. A limiting groove 9 that matches the limiting protrusion 8 is provided at the through hole 6. When the coating turntable 22 and the clamping member 23 are sleeved on the rotating shaft 21, the limiting protrusion 8 is located in the limiting groove 9. The cooperation between the limiting protrusion 8 and the limiting groove 9 provides precise positioning for the installation of the coating turntable 22 and the clamping member 23 on the rotating shaft 21. When assembling, once the limiting protrusion 8 is engaged with the limiting groove 9, it can ensure that the coating turntable 22 and the clamping member 23 are in the predetermined and correct axial position, effectively preventing the components from axially displacing along the rotating shaft 21 due to factors such as vibration and centrifugal force during equipment operation.

[0031] like Figure 2 and Figure 3 As shown, the top of the coating turntable 22 is provided with a limiting ring 10 that is adapted to the clamping member 23. The upper part of the clamping member 23 is provided with an annular protrusion 11. An annular groove 12 is formed between the annular protrusion 11 and the limiting ring 10. For the production of paper drums of different specifications, glue can also be applied to the clamping member 23 in actual use. The annular groove 12 makes way for the rolled edge of the paper drum, improving the practicality of the whole device.

[0032] like Figure 1As shown, the glue supply assembly 4 includes a glue delivery pipe 41, a glue support frame 42, and a control valve 43. The support frame is fixed on the platform 1, and the glue delivery pipe 41 is located on the support frame. One end of the glue delivery pipe 41 is located above the application turntable 22, and the other end of the glue delivery pipe 41 is used to connect to the glue delivery equipment. The control valve 43 is located on the glue delivery pipe 41. When dealing with paper buckets of different sizes, glues of different viscosities, or when adjusting the production process, the glue supply parameters can be adjusted as needed by operating the control valve 43. For example, when producing small paper buckets, the flow rate can be reduced to avoid waste, and when using high-viscosity glue, the flow rate can be appropriately slowed down to ensure uniform glue supply, greatly improving the versatility and adaptability of the equipment.

[0033] like Figure 1 As shown, the support frame is provided with a slot 13, and the glue delivery tube 41 is locked in the slot 13. The design of the slot 13 makes the installation of the glue delivery tube 41 extremely simple, and the position of the glue delivery tube 41 above the application turntable 22 can be adjusted according to the actual situation.

[0034] like Figure 2 As shown, a bearing 14 is provided at the connection between the rotating shaft 21 and the stand 1. The presence of the bearing 14 greatly reduces the friction between the rotating shaft 21 and the stand 1, and extends the service life of the device.

[0035] Working principle:

[0036] In use, place this device close to the cup mold in the prior art, then place the paper container on the cup mold, and make the edge of the coating turntable 22 contact the edge of the paper container. Then, open the cup mold to make the paper container rotate at a uniform speed, start the drive motor 3 of this device, drive motor 3 to drive the rotating shaft 21 to rotate at a uniform speed, and then drive the coating turntable 22 connected to the rotating shaft 21 to rotate. The glue delivery pipe 41 in the glue supply assembly 4, supported by the support frame, delivers the glue supplied by the glue delivery equipment to the top of the coating turntable 22. The glue flow rate is adjusted by the control valve 43 to adapt to different production needs. Under the uniform rotation of the coating turntable 22, the glue moves towards the edge of the coating turntable 22 under the action of centrifugal force, and then the glue is evenly applied to the edge of the paper container.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
