Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to an automatic glue-applying machine for paper boxes. Background Technology

[0002] Glue application machines, also known as adhesive applicators or glue spraying machines, are key pieces of equipment in automated production within the packaging industry. They are widely used in the gluing processes of products such as premium boxes, gift boxes, wine boxes, and book boxes. Their core function is to control the glue flow rate and spray speed via pneumatic or electric means to achieve precise glue application. They support various modes, including dot, line, and strip spraying, to adapt to different product needs. The equipment can handle various fluid adhesives such as white glue, hot melt glue, and all-purpose glue, and is equipped with an intelligent glue volume adjustment system, which can save up to 40% of glue consumption.

[0003] From a technical standpoint, the glue application machine employs high-precision sensors and an electronic control system to ensure uniform glue application. Some models feature dynamic glue application capabilities, achieving a maximum speed of 38 pieces per minute with smooth operation, preventing workpiece scratches. Furthermore, the equipment supports CAD drawing import and automated path memory, making it easy to operate; even unskilled workers can be trained quickly and efficiently.

[0004] In the existing technology, glue application machines are widely used in paper box production. When operating a glue application machine, it is necessary to position the paper box. Currently, some positioning blocks are usually pasted on the workbench surface to help position the paper box. However, these positioning blocks are generally difficult to move, which means that when positioning different products, the position of the positioning blocks needs to be changed again. After moving and re-gluing, a certain amount of time is required to wait for the glue to harden, which greatly affects the efficiency of paper box positioning. Utility Model Content

[0005] Therefore, it is necessary to provide an automatic glue applicator for paper boxes, which addresses the issue that the positioning blocks are generally difficult to move, requiring repositioning when positioning different products. After repositioning and re-adhesion, a certain amount of time is needed for the glue to harden, which greatly affects the efficiency of paper box positioning.

[0006] An automatic glue applicator for paper boxes includes: an automatic glue applicator body, a slide rail, a slide plate, and a support plate. The slide rail, slide plate, and support plate are disposed on the automatic glue applicator body. The slide plate slides above the slide rail. The support plate is fixed on the slide plate and is located below the glue nozzle of the automatic glue applicator body.

[0007] Two support components are located on both sides above the support plate. A limiting frame is provided on the side of the two support components that are close to each other. Telescopic rods are symmetrically and movably connected inside the two limiting frames. The two telescopic rods slide above the support plate.

[0008] In one embodiment, the support assembly includes a support block fixedly connected to the support plate, a support rod slidably inserted inside the support block, and one end of the support rod being fixedly connected to the outer wall of the limiting frame.

[0009] In one embodiment, a knob is threadedly connected to the upper part of the support rod, one end of which is inserted into the interior of the support rod and fits against the outer wall of the support rod.

[0010] In one embodiment, support rails are fixedly connected to the lower sides of the limiting frame, and the support rails slide on the upper surface of the support plate.

[0011] In one embodiment, limit grooves are provided on both upper sides, and multiple support rails are located in the limit grooves and slide inside them.

[0012] In one embodiment, both ends of the telescopic rod are inserted into the interior of the limiting frame and are fixedly connected to a pointer. One side of the pointer extends to the top of the limiting frame, and the internal thread of the pointer is engaged with a limiting post. One end of the limiting post is in contact with the outer wall of the limiting frame.

[0013] In one embodiment, the two limiting brackets extend toward the side closer to the support assembly, and the limiting brackets and the telescopic rod are set at an angle of 90°.

[0014] In one embodiment, scales are provided on both sides of the upper part of the support plate and on the side of the two limiting frames that are close to each other.

[0015] Beneficial effects

[0016] 1. The support plate is installed above the slide plate, which slides along the surface of the slide rail. Move the support plate to below the glue gun of the automatic glue applicator. Place the paper box above the support plate. The position of the limiting frame is changed by the support component. The two telescopic rods slide inside the limiting frame. The two limiting frames and the two telescopic rods quickly position the coordinates of the paper box in four directions. Place the paper box between the two limiting frames and the two telescopic rods, and then the glue gun performs the glue application operation. The paper box can be quickly and effectively positioned by the two limiting frames and the two telescopic rods, which can change position, increasing the glue application efficiency.

[0017] 2. Rollers are installed below the support rail to reduce friction between the support rail and the upper surface of the support plate during sliding. A limiting groove on the upper surface of the support plate limits the lower part of the support rail, improving stability when the support rail slides within the limiting groove. A pointer is fixed at both ends of the telescopic rod. While supporting the limiting post, the pointer also points to the scale, allowing workers to clearly see the position of the limiting post and easily position the glue gun of the automatic glue applicator. As the limiting post rotates and moves downwards, its lower end presses against the upper surface of the limiting frame, and the extended surface of the limiting frame contacts the limiting post, quickly fixing its position and ensuring stability during positioning.

[0030] The following is combined with Figures 1-4 This invention describes an automatic glue applicator for paper boxes.

[0031] In one embodiment, an automatic glue applicator for cardboard boxes includes: an automatic glue applicator body 100, a slide rail 200, a slide plate 300, a support plate 400, and support components 500. The slide rail 200, slide plate 300, and support plate 400 are disposed on the automatic glue applicator body 100. The slide plate 300 slides above the slide rail 200. The support plate 400 is fixed on the slide plate 300 and located below the glue nozzle of the automatic glue applicator body 100. Two support components 500 are disposed on both sides above the support plate 400. A limiting frame 600 is provided on the side of the two support components 500 that is close to each other. The two limiting frames 600 are symmetrically and movably connected to telescopic rods 700 inside. The two telescopic rods 700 slide above the support plate 400.

[0032] In this embodiment, the automatic glue applicator body 100 is a three-axis automatic glue applicator, which can perform glue application on flat cardboard boxes. The slide plate 300 slides above the slide rail 200 to change the position of the support plate 400. The support plate 400 is supported by two support components 500 above the limiting frame 600. The two limiting frames 600 move horizontally above the support plate 400 to limit the two sides of the cardboard box.

[0033] When it is necessary to fix the position of the cardboard box, place the cardboard box on the support plate 400, control the support component 500 to change the position of the limiting frame 600, the two limiting frames 600 position the outer wall of the cardboard box, and then slide the telescopic rod 700 along the inside of the limiting frame 600, so that the side of the two telescopic rods 700 that are close to each other is attached to the other two sides of the cardboard box, so that the four sides of the cardboard box are positioned. After the position of the cardboard box is fixed, the automatic glue applicator body 100 can be started to perform the glue application operation. Repeatedly pick up the cardboard box and place the new cardboard box to quickly apply glue to the cardboard box, which greatly increases the work efficiency.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the support assembly 500 includes a support block 501 fixedly connected to the support plate 400, a support rod 502 slidably inserted into the support block 501, and one end of the support rod 502 fixedly connected to the outer wall of the limit frame 600.

[0035] In this embodiment, the support rod 502 is inserted into the support block 501 and slides. The support rod 502 supports the limiting frame 600 and is used to change the position of the limiting frame 600. Plugs are installed at both ends of the support rod 502 so that the support rod 502 can only slide inside the support block 501.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, a knob 503 is threadedly connected to the upper part of the support rod 502. One end of the knob 503 is inserted into the interior of the support rod 502 and fits against the outer wall of the support rod 502.

[0037] In this embodiment, the support rod 502 is fixed above the support plate 400 by bolts. One end of the support rod 502 extends upward. Rotating the knob 503 causes the internal threaded column to slide downward. When the knob 503 contacts the support rod 502, the support rod 502 can be fixed inside the support block 501.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, support rails 601 are fixedly connected to the lower sides of the limiting frame 600. The support rails 601 slide on the upper surface of the support plate 400. Limit grooves 401 are opened on both sides above. Multiple support rails 601 slide inside the limit grooves 401.

[0039] In this embodiment, rollers are installed below the support rail 601 to reduce the friction between the support rail 601 and the upper surface of the support plate 400 during sliding. The limiting groove 401 opened on the upper surface of the support plate 400 is used to limit the lower part of the support rail 601, so that when the support rail 601 slides inside the limiting groove 401, the stability of the limiting frame 600 during movement is improved.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, both ends of the telescopic rod 700 are inserted into the interior of the limiting frame 600 and are fixedly connected to a pointer 701. One side of the pointer 701 extends to the top of the limiting frame 600. The internal thread of the pointer 701 is engaged with a limiting post 702. One end of the limiting post 702 is in contact with the outer wall of the limiting frame 600. The two limiting frames 600 extend towards the side closer to the support assembly 500. The angle between the limiting frame 600 and the telescopic rod 700 is set at 90°. Scales 703 are provided on both sides of the top of the support plate 400 and on the side of the two limiting frames 600 that are close to each other.

[0041] In this embodiment, pointer 701 is fixed at both ends of telescopic rod 700. While pointer 701 supports limit post 702, limit post 702 also points to scale 703, which makes it clearer for workers to the position of limit post 702 and facilitates workers to position the glue gun of automatic glue applicator body 100. When limit post 702 rotates and moves downward, the lower end of limit post 702 will press against the upper surface of limit frame 600, and the extension surface of limit frame 600 will contact limit post 702, which can quickly fix the position of limit post 702 and ensure the stability of the two limit posts 702 during positioning.

[0042] Working principle:

[0043] In use, the support plate 400 is installed above the slide plate 300, which slides along the surface of the slide rail 200. The support plate 400 is moved to a position below the glue gun of the automatic glue applicator body 100. The paper box is placed above the support plate 400. The position of the limiting frame 600 is changed by the support component 500. The two telescopic rods 700 slide inside the limiting frame 600. The two limiting frames 600 and the two telescopic rods 700 quickly position the coordinates of the paper box in four directions. The paper box is placed between the two limiting frames 600 and the two telescopic rods 700, and then the glue gun performs the glue application operation. The adjustable position of the two limiting frames 600 and the two telescopic rods 700 allows for quick and effective positioning of the paper box, increasing glue application efficiency.

[0044] It should be noted that the automatic glue applicator body 100, slide rail 200, slide plate 300 and telescopic rod 700 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the automatic glue applicator body 100 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
