Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to an adjustable packaging box side gluing device. Background Technology

[0002] Packaging boxes, as widely used containers, play a vital role in logistics, retail, and daily life. They are typically made of cardboard, plastic, or other composite materials, and their outer layers are often printed with various patterns and text to enhance visual appeal and brand recognition. To ensure these patterns and text adhere firmly to the box surface, adhesive is usually applied to the sides. This adhesive not only secures the outer patterns but also strengthens the box's structural integrity, making it more durable during transportation and storage.

[0003] Currently, various automated glue-applying machines are available on the market. These machines control the movement trajectory of the glue applicator through preset programs, achieving an automated glue-applying process. These machines are typically equipped with high-precision sensors and control systems, capable of automatically adjusting the glue-applying path according to the size and shape of the packaging box, ensuring uniformity and consistency. However, despite their excellent performance in glue-applying accuracy and efficiency, these machines still have some limitations.

[0004] The main drawback of existing glue-applying equipment lies in its fixed glue application rate. Regardless of the size of the packaging box, the equipment applies glue according to a preset amount. While this design is suitable for small and medium-sized packaging boxes, when dealing with large packaging boxes, the fixed glue application rate is often insufficient to provide adequate adhesion, leading to the outer pattern easily peeling off or the packaging box structure being less stable. Utility Model Content

[0005] To overcome the drawback of fixed glue application amount, this utility model provides a packaging box side glue application device with adjustable glue application amount.

[0006] An adjustable packaging box side coating device includes a body and a glue inlet tube. A connecting frame is connected to the body, and a glue applicator is disposed below the connecting frame. An adjustment component is disposed between the glue applicator and the connecting frame to adjust the rotation angle of the glue applicator. Several glue applicators with different orifice diameters are disposed inside the glue applicator. The glue inlet tube is connected to the connecting frame, and a ball plug is slidably connected to the bottom of the glue inlet tube. The ball plug is sealed to the top of the glue applicator, and a through hole is opened in the middle of the ball plug. An elastic element is disposed inside the connecting frame. One end of the elastic element is connected to the bottom of the glue inlet tube, and the other end is connected to the ball plug. A fixing component is disposed on the glue applicator to fix the glue applicator tube.

[0007] Furthermore, the adjustment assembly includes an adjustment ring, a ball head bolt is threaded to the lower side of the connecting frame, the adjustment ring is rotatably connected to the bottom of the connecting frame, the glue applicator is fixedly connected to the adjustment ring, and the top of the adjustment ring has several limiting grooves, with the ball head bolt engaging with the limiting grooves for limiting.

[0008] Furthermore, the fixing component includes a pin, the glue applicator is connected to a limiting plate, several positioning plates are connected to the side of the glue applicator, the limiting plate is slidably connected to the glue applicator, the limiting plate is located between two of the positioning plates, the pin is slidably connected between two adjacent positioning plates, and the pin is interference-fitted with the limiting plate.

[0009] Furthermore, a protective sleeve is fitted over the bottom of each of the adhesive tubes.

[0010] Furthermore, a light is installed at the bottom of the glue applicator.

[0011] Furthermore, a heat insulation sleeve is provided on the side of the adjusting ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By adjusting the components, the adjusting ring and the glue applicator are rotated together, thereby enabling the selection and angle adjustment of the glue applicator tube, and ultimately achieving the purpose of adjusting the amount of glue applied according to different packaging box sizes.

[0014] 2. By using a fixing component, the limiting plate and the glue application tube are slidably fitted together, and then fixed by an interference fit between the pin and the limiting plate, thereby achieving stable fixation of the glue application tube and ultimately ensuring the accuracy and consistency of the glue application process.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. 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 the present invention based on the specific circumstances.

[0020] Example: An adjustable packaging box side adhesive applicator, such as... Figures 1-3 As shown, the device includes a body 1, a connecting frame 101, a glue applicator 2, a glue inlet tube 20, a glue applicator tube 3, a ball plug 9, an elastic element 10, an adjustment component, and a fixing component. The connecting frame 101 is connected to the body 1, and the glue applicator 2 is located below the connecting frame 101. An adjustment component is located between the glue applicator 2 and the connecting frame 101 to adjust the rotation angle of the glue applicator 2. The glue applicator 2 contains several glue applicator tubes 3 with different orifice diameters. The glue applicator tubes 3 are telescopic. The glue inlet tube 20 is connected to the connecting frame 101. The bottom of the glue inlet tube 20 is slidably connected to the ball plug 9, which is sealed to the top of the glue applicator tube 3. The ball plug 9 has a through hole in the middle. The connecting frame 101 contains an elastic element 10, one end of which is connected to the bottom of the glue inlet tube 20, and the other end is connected to the ball plug 9. The glue applicator 2 is equipped with a fixing component for fixing the glue applicator tubes 3.

[0021] like Figure 2 and Figure 3 As shown, the adjustment assembly includes an adjustment ring 4 and a ball head bolt 5. The body of the adjustment ring 4 is a bearing. The ball head bolt 5 is threadedly connected to the lower side of the connecting frame 101. The inner ring of the adjustment ring 4 is fixedly connected to the connecting frame 101, and the outer ring of the adjustment ring 4 is fixedly connected to the glue applicator 2. The glue applicator 2 is fixedly connected to the adjustment ring 4. Several limiting grooves 401 are opened on the top of the adjustment ring 4, and the ball head bolt 5 is limited and engaged with the limiting grooves 401.

[0022] like Figure 2 and Figure 3 As shown, the fixing assembly includes a limiting plate 6, a pin 7, and a positioning plate 8. The glue applicator 3 is connected to the limiting plate 6. Several positioning plates 8 are connected to the side of the glue applicator 2. The limiting plate 6 is slidably connected to the glue applicator 2. The limiting plate 6 is located between two positioning plates 8. A pin 7 is slidably connected between two adjacent positioning plates 8. The pin 7 is interference-fitted with the limiting plate 6.

[0023] like Figure 2As shown, it also includes a protective sleeve 11. Each glue application tube 3 has a protective sleeve 11 fitted at its bottom to prevent dust or other foreign objects from entering the glue application tube 3 and causing blockage or contamination. When it is necessary to replace the glue application tube 3, the operator only needs to remove the protective sleeve 11 for use, which is simple and convenient.

[0024] like Figure 2 As shown, it also includes a lighting lamp 12. The bottom of the glue applicator 2 is equipped with a lighting lamp 12. The lighting lamp 12 can provide sufficient lighting in low light environments, making it convenient for workers to observe the model and status of the glue applicator tube 3. The design of the lighting lamp 12 enables workers to quickly and accurately select the appropriate glue applicator tube 3, thereby improving work efficiency.

[0025] like Figure 2 As shown, it also includes a heat insulation sleeve 13. The heat insulation sleeve 13 is fitted on the side of the adjusting ring 4. Because the temperature of the melted glue is high, the adjusting ring 4 will heat up after working for a long time. The heat insulation sleeve 13 can effectively reduce the surface temperature of the adjusting ring 4, prevent workers from being burned during operation, and improve the safety and comfort of operation.

[0026] After selecting a suitable applicator tube 3 according to the size requirements of the packaging box, the staff first rotates the ball head bolt 5 to disengage it from the limiting groove 401 on the adjusting ring 4. Then, the staff holds the adjusting ring 4 with the heat insulation sleeve 13 and rotates it. The adjusting ring 4 drives the entire applicator 2 to rotate, aligning the selected applicator tube 3 with the glue inlet tube 20. Because the melted glue is at a high temperature, the heat insulation sleeve 13 effectively prevents burns to the staff. When the adjusting ring 4 rotates, the ball plug 9 is squeezed by the applicator tube 3, sliding within the glue inlet tube 20 and compressing the elastic element 10. When the applicator tube 3 extends or retracts, the ball plug 9 maintains a sealed contact with the top of the applicator tube 3 under the action of the elastic element 10. After the applicator tube 3 is aligned, the rebound force of the elastic element 10 pushes the ball plug 9 back into the applicator tube 3, ensuring a seal. Finally, the ball head bolt 5 is tightened to re-insert it into the limiting groove 401, fixing the position of the adjusting ring 4 and completing the selection and angle adjustment of the applicator tube 3.

[0027] When replacing the adhesive applicator tube 3, the worker first pulls out the pin 7 to release the fixing of the limiting plate 6. Then, the adhesive applicator tube 3 to be used is stretched through the limiting plate 6, while the previously used adhesive applicator tube 3 is retracted. When the limiting plate 6 moves between the two positioning plates 8, the pin 7 is inserted. Because the pin 7 and the limiting plate 6 are interference-fitted, the pin 7 can firmly fix the limiting plate 6, preventing it from sliding accidentally. This design ensures the stability of the adhesive applicator tube 3 during use and avoids affecting the adhesive application effect due to loosening of the adhesive applicator tube 3.

[0028] After the glue application tube 3 is replaced, the device is turned on. The melted glue enters the ball plug 9 from the glue inlet tube 20, and then enters the glue application tube 3 after passing through the ball plug 9. Finally, the glue is applied to the packaging box. The light 12 makes it easy for the staff to observe the model of the glue application tube 3, so as to facilitate the staff to select it. The bottom of the unused glue application tube 3 is covered with a protective cover 11 to prevent foreign objects from entering the glue application tube 3.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
