Description

Technical Field

[0001] This utility model relates to the field of box gluing machines, specifically to a gluing mechanism for a box gluing machine. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency.

[0003] Chinese utility model patent publication number "CN206690615U" discloses a gluing machine with a heating device, including a gluing device for applying glue to cardboard and a pressing device for pressing and bonding the cardboard with uniformly applied glue. The gluing device includes a glue box for storing glue, a gluing wheel for applying glue to the cardboard, and a heating mechanism for heating the glue in the glue box. The gluing wheel is in contact with the glue stored in the glue box.

[0004] However, the aforementioned box-gluing machine still has the following drawbacks:

[0005] First, the gluing roller can only apply glue to a fixed position on the cardboard and cannot be adjusted according to the size of the cardboard and the conveying position. At the same time, the gluing roller can only apply glue to the bottom of the cardboard, which is not suitable for the gluing of double-layer cardboard boxes, making it inconvenient.

[0006] Secondly, when the cardboard passes through the gluing roller, glue will fall onto the outer wall of the box, causing glue to accumulate on the side of the box and making it difficult to clean.

[0007] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0008] The purpose of this invention is to provide a gluing mechanism for a carton gluing machine that offers uniform dispensing and high adaptability, thereby solving the aforementioned problems in the prior art.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a gluing mechanism for a carton gluing machine, including a frame, a conveying device and a gluing device on the frame, characterized in that: the gluing device includes a glue box, a gluing component and an adjusting component, the glue box is detachably connected to the frame, the adjusting component is used to adjust the position of the gluing component, and the gluing component is used to draw glue from the glue box and apply it to the top of the cardboard.

[0010] By adopting the above technical solution: the cardboard is transported to the gluing device by the conveying device, the gluing component extracts the glue from the glue box and then applies the glue to the bonding area of ​​the cardboard, realizing rapid gluing of the cardboard. The adjusting component can adjust the position of the gluing component relative to the frame, thereby adjusting the glue application position of the gluing component and improving the applicability of the gluing mechanism.

[0011] The gluing mechanism of the aforementioned box gluing machine can be further configured as follows: the adjusting component includes an adjusting seat, an adjusting bracket, and an adjusting screw. The gluing component is mounted on the adjusting bracket. The adjusting seat is provided with several sets of first adjusting slide rails, and the adjusting bracket is provided with several sets of first adjusting sliders. The first adjusting sliders slide in cooperation with the first adjusting slide rails. An adjusting hole is provided in the middle of the adjusting seat. An adjusting plate is provided on the adjusting bracket. One end of the adjusting screw rotates in cooperation with the adjusting bracket, and the other end is threadedly connected to an adjusting block. The adjusting plate and the adjusting block are linked together. An adjusting handwheel is also provided at the end of the adjusting screw.

[0012] By adopting the above technical solution: when the position of the gluing component needs to be adjusted, rotating the adjusting handwheel drives the adjusting screw to rotate, which in turn moves the adjusting block along the axis of the adjusting screw. The adjusting block pushes or pulls the adjusting plate, which in turn moves the adjusting bracket horizontally along the first adjusting slide rail on the adjusting seat. This achieves rapid adjustment of the position of the adjusting bracket and the gluing component relative to the frame, and enables fine, stepless position adjustment, ensuring the accuracy of the gluing and dispensing position and effectively improving the equipment's adaptability to different specifications of cardboard or bonding requirements.

[0013] The gluing mechanism of the above-mentioned box gluing machine can be further configured as follows: the adjusting bracket is provided with several sets of second adjusting slide rails on one side relative to the first adjusting slider, the second adjusting slide rails are slidably fitted with the second adjusting slider, the second adjusting slider is provided with an adjusting support plate, the gluing assembly is provided on the adjusting support plate, the adjusting support plate is provided with an adjusting cylinder, the body of the adjusting cylinder is detachably connected to the adjusting support plate, the output end is linked with the adjusting plate, and the operation of the adjusting cylinder pushes the adjusting support plate to slide axially along the adjusting slide rail.

[0014] By adopting the above technical solution, a second adjusting slide rail and a second adjusting slider are added to the adjusting bracket, enabling the adjusting support plate to move independently and quickly linearly relative to the adjusting bracket. When it is necessary to change the position of the gluing component, the adjusting cylinder is activated, and its output end pushes or pulls the adjusting support plate. The adjusting support plate then drives the second adjusting slider to slide axially along the second adjusting slide rail. The position adjustment response is rapid and the operation is convenient, which significantly improves the production efficiency of the gluing mechanism and its flexibility to adapt to different working conditions, and provides richer adjustment methods to meet more complex production needs.

[0015] The gluing mechanism of the above-mentioned box gluing machine can be further configured as follows: the gluing assembly includes a dispensing frame disposed on the adjusting support plate, a dispensing head disposed on the dispensing frame, a pump body for drawing glue on one side of the glue box, a glue dispensing head having a glue outlet pipe, one end of the glue outlet pipe being connected to the pump body and the other end being connected to the dispensing head, a coating plate being disposed on the frame, the coating plate having a plurality of coating openings, and a scraper being inclinedly disposed at the coating openings.

[0016] By adopting the above technical solution: the pump body draws glue from the glue box and delivers it stably to the dispensing head through the glue outlet tube. When the cardboard is transported to the top of the glue coating plate by the conveying device, the dispensing head accurately applies or flows the glue onto the parts of the cardboard that need to be bonded. In addition, the glue dispensing nozzle on the glue coating plate can allow the dripping glue to fall back into the glue box, preventing glue waste. At the same time, the inclined scraper inside the glue dispensing nozzle can effectively scrape and smooth the applied glue after the cardboard is glued, eliminating uneven glue beads or glue strips, ensuring that the glue layer thickness is consistent and evenly distributed, and preventing glue from contaminating non-bonding areas, thereby enhancing the bonding strength and aesthetics, while reducing glue waste.

[0017] The gluing mechanism of the aforementioned box gluing machine can be further configured as follows: the conveying device includes a conveying roller, a drive wheel, and a conveyor belt. The drive wheel is rotatably mounted on the frame. The conveyor belt is linked with the drive wheel. The conveying roller is linked with the conveyor belt. A support component is provided in the middle of the conveyor belt. The support component is used to support the conveyor belt.

[0018] By adopting the above technical solution: the drive wheel rotates to drive the conveyor belt to circulate, which in turn drives the conveyor rollers to rotate, together forming the conveying channel of the cardboard. The cardboard is placed on the conveyor belt and is stably conveyed forward under the combined action of the conveyor belt and the conveyor rollers until it reaches the gluing station. The support component provides a solid support force for the conveyor belt, effectively preventing the conveyor belt from sagging or deforming excessively when loaded with cardboard, and ensuring that the conveyor belt remains straight and stable in the critical working section.

[0019] The gluing mechanism of the above-mentioned box gluing machine can be further configured as follows: the support assembly includes a support rod, the support rod has a support groove, the support groove has a plurality of support brackets, one end of the support bracket is hinged to the support rod and the other end is provided with a support shaft, and a plurality of support wheels are provided on both sides of the support shaft.

[0020] By adopting the above technical solution: the support rod is fixed to the frame, the support groove provides installation space and freedom of movement for the hinged end of the support bracket, one end of the support bracket is hinged to the support rod, and the other end is equipped with several support wheels through the support shaft. The support wheels directly contact the lower surface of the conveyor belt, realizing multi-point support, and can adaptively fine-tune the angle according to the sag of the conveyor belt and the running state to ensure that the support wheels are always in contact with the bottom surface of the conveyor belt. In addition, multiple support wheels are distributed along the support shaft to form one or more effective support lines, which evenly support the conveyor belt and cardboard, effectively preventing the conveyor belt from sagging and deforming, and improving the running stability and load-bearing capacity of the conveyor belt.

[0021] The gluing mechanism of the above-mentioned box gluing machine can be further configured as follows: an adjustment groove is provided on the frame, and an adjustment roller is provided in the adjustment groove. The adjustment roller is used to adjust the tension of the conveyor belt.

[0022] By adopting the above technical solution, the total path length of the conveyor belt can be adjusted by moving the position of the adjusting roller along the adjusting groove, thereby realizing the adjustment of the tension of the conveyor belt. When the conveyor belt becomes loose and elongated due to long-term use, the adjusting groove plays a precise guiding and positioning role for the movement of the adjusting roller. The conveyor belt can be tightened by sliding the adjusting roller along the adjusting groove to restore its required tension. Conversely, when it is over-tensioned, it can be appropriately relaxed to ensure that the tension adjustment process is stable and reliable.

[0023] The beneficial effects of this utility model are as follows: By rotating the adjustment handwheel to drive the screw for precise stepless horizontal translation, or by activating the adjustment cylinder to achieve rapid and independent movement of the gluing component, the convenience and response speed of the gluing component position adjustment are significantly improved. At the same time, with the glue nozzle equipped with an inclined scraper, not only can dripping glue be effectively recovered to reduce waste, but the glue layer can also be scraped and smoothed evenly to eliminate glue beads, ensuring that the glue layer thickness is uniform and confined to the bonding area, greatly improving the bonding strength and aesthetics. In addition, the conveying device adopts multiple support wheels and adjustment wheels, which provide adaptive, uniform and stable support for the conveyor belt, effectively preventing deformation and sagging, and ensuring the smoothness and precise positioning of the cardboard conveying.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figures 1 to 5 The glue application mechanism of a carton gluing machine shown includes a frame 1, a conveying device 2, and a glue application device 3. The glue application device 3 includes a glue box 31, a glue application assembly 32, and an adjusting component 33. The glue box 31 is detachably connected to the frame 1. The adjusting component 33 is used to adjust the position of the glue application assembly 32. The glue application assembly 32 is used to draw glue from the glue box 31 and apply it to the cardboard. The cardboard is transported to the glue application device 3 via the conveying device 2. The glue application assembly 32 draws glue from the glue box 31 and then applies the glue to the bonding area of ​​the cardboard, achieving rapid glue application. The adjusting component 33 can adjust the position of the glue application assembly 32 relative to the frame 1, thereby adjusting the glue application position of the glue application assembly 32 and improving the applicability of the glue application mechanism.

[0033] The adjustment assembly 33 includes an adjustment seat 331, an adjustment bracket 332, and an adjustment screw 333. The gluing assembly 32 is mounted on the adjustment bracket 332. The adjustment seat 331 is provided with several sets of first adjustment slide rails 3311, and the adjustment bracket 332 is provided with several sets of first adjustment sliders 3321. The first adjustment sliders 3321 are slidably engaged with the first adjustment slide rails 3311. An adjustment hole 3312 is provided in the middle of the adjustment seat 331. The adjustment bracket 332 is provided with an adjustment plate 3322. One end of the adjustment screw 333 is rotatably engaged with the adjustment bracket 332, and the other end is threadedly connected to an adjustment block 3331. The adjustment plate 3322 is linked with the adjustment block 3331. An adjustment handwheel 334 is also provided at the end of the adjustment screw 333. When the position of the gluing assembly 32 needs to be adjusted, the adjusting handwheel 334 is rotated to drive the adjusting screw 333 to rotate, which in turn drives the adjusting block 3331 to move along the axis of the adjusting screw 333. The adjusting block 3331 pushes or pulls the adjusting plate 3322, which in turn drives the adjusting bracket 332 to move horizontally along the first adjusting slide rail 3311 on the adjusting seat 331. This enables rapid adjustment of the position of the adjusting bracket 332 and the gluing assembly 32 relative to the frame 1, and allows for fine, stepless position adjustment, ensuring the accuracy of the gluing and dispensing position and effectively improving the equipment's adaptability to different specifications of cardboard or bonding requirements.

[0034] The adjusting bracket 332 is provided with several sets of second adjusting slide rails 3323 on one side relative to the first adjusting slider 3321. The second adjusting slide rails 3323 are slidably fitted with the second adjusting sliders 3323. The second adjusting sliders 3323 are provided with adjusting support plates 335. The gluing assembly 32 is provided on the adjusting support plate 335. The adjusting support plate 335 is provided with adjusting cylinders 336. The body of the adjusting cylinder 336 is detachably connected to the adjusting support plate 335, and the output end is linked with the adjusting plate 3322. The operation of the adjusting cylinder 336 pushes the adjusting support plate 335 to slide axially along the adjusting slide rails. A second adjusting slide rail 3323 and a second adjusting slider 3323 are added to the adjusting bracket 332, enabling the adjusting support plate 335 to move independently and quickly linearly relative to the adjusting bracket 332. When it is necessary to change the position of the gluing assembly 32, the adjusting cylinder 336 is activated, and its output end pushes or pulls the adjusting support plate 335. The adjusting support plate 335 then drives the second adjusting slider 3323 to slide axially along the second adjusting slide rail 3323. The position adjustment response is rapid and the operation is convenient, which significantly improves the production efficiency of the gluing mechanism and the flexibility to adapt to different working conditions, and provides richer adjustment means to meet more complex production needs.

[0035] The glue application assembly 32 includes a glue dispensing frame 321 mounted on an adjusting support plate 335 and a glue dispensing head 322 mounted on the glue dispensing frame 321. A pump body 323 for drawing glue is provided on one side of the glue box 31. The glue dispensing head 322 is provided with a glue outlet tube 324. One end of the glue outlet tube 324 is connected to the pump body 323 and the other end is connected to the glue dispensing head 322. A glue coating plate 325 is provided on the frame 1. The glue coating plate 325 has several glue application ports 326. A scraper 327 is inclinedly arranged at each glue application port 326. Pump 323 draws glue from glue box 31 and delivers it stably to dispensing head 322 through glue outlet pipe 324. When the cardboard is transported to the top of glue plate 325 by conveyor device 2, dispensing head 322 accurately applies or flows glue to the parts of the cardboard that need to be bonded. In addition, glue outlet 326 on glue plate 325 can allow dripping glue to fall back into glue box 31, preventing glue waste. At the same time, the inclined scraper 327 inside glue outlet 326 can effectively scrape and smooth the applied glue after the cardboard is glued, eliminating uneven glue beads or strips, ensuring consistent glue layer thickness and uniform distribution, and preventing glue from contaminating non-bonding areas, thus enhancing bonding strength and aesthetics while reducing glue waste.

[0036] The conveying device 2 includes a conveyor roller 21, a drive wheel 22, and a conveyor belt. The drive wheel 22 is rotatably mounted on the frame 1. The conveyor belt is linked to the drive wheel 22, and the conveyor roller 21 is linked to the conveyor belt. A support assembly 23 is provided in the middle of the conveyor belt to support it. The rotation of the drive wheel 22 drives the conveyor belt to circulate, which in turn drives the conveyor roller 21 to rotate, together forming the conveying channel for the cardboard. The cardboard is placed on the conveyor belt and, under the combined action of the conveyor belt and the conveyor roller 21, is stably conveyed forward until it reaches the gluing station. The support assembly 23 provides a stable support for the conveyor belt, effectively preventing excessive sagging or deformation of the conveyor belt when loaded with cardboard, and ensuring that the conveyor belt remains straight and stable during critical working sections.

[0037] The support assembly 23 includes a support rod 231, the support rod 231 has a support groove 232, the support groove 232 has a plurality of support brackets 233, one end of the support bracket 233 is hinged to the support rod 231, and the other end is provided with a support shaft 234, and a plurality of support wheels 235 are provided on both sides of the support shaft 234. The support rod 231 is fixed to the frame 1. The support groove 232 provides installation space and freedom of movement for the hinged end of the support bracket 233. One end of the support bracket 233 is hinged to the support rod 231, giving it a certain swing adjustment capability. The other end is equipped with several support wheels 235 through the support shaft 234. The support wheels 235 directly contact the lower surface of the conveyor belt, realizing multi-point support. They can also adaptively fine-tune the angle according to the sag of the conveyor belt and the running state, ensuring that the support wheels 235 are always in contact with the bottom surface of the conveyor belt. In addition, multiple support wheels 235 are distributed along the support shaft 234 to form one or more effective support lines, which evenly support the conveyor belt and cardboard, effectively preventing the conveyor belt from sagging and deforming, and improving the running stability and load-bearing capacity of the conveyor belt.

[0038] An adjustment groove 11 is provided on the frame 1, and an adjustment roller 12 is provided in the adjustment groove 11. The adjustment roller 12 is used to adjust the tension of the conveyor belt. By moving the position of the adjustment roller 12 along the adjustment groove 11, the total path length of the conveyor belt can be adjusted, thereby realizing the adjustment of the tension of the conveyor belt. When the conveyor belt becomes loose and elongated due to long-term use, the adjustment groove 11 plays a role in precisely guiding and positioning the movement of the adjustment roller 12. The conveyor belt can be tightened by sliding the adjustment roller 12 along the adjustment groove 11 to restore its required tension. Conversely, when it is over-tensioned, it can be appropriately loosened to ensure that the tension adjustment process is stable and reliable.

[0039] The working principle of this embodiment is as follows: Before applying glue to the cardboard, the adjusting cylinder 336 is activated. The adjusting cylinder 336 pushes the adjusting cardboard to move relative to the adjusting plate 3322, which drives the gluing assembly 32 to move as a whole. Then, the adjusting handwheel 334 is rotated, and the adjusting screw 333 rotates synchronously, which drives the adjusting plate 3322 to move axially along the first adjusting slide rail 3311. The position of the gluing assembly 32 is finely adjusted so that the glue dispensing head 322 is located on the gluing line of the cardboard. Then, the gluing machine is started, and the conveyor belt drives the cardboard to move. When the cardboard moves to the glue dispensing head 322, the pump body 323 draws glue from the glue box 31 and outputs it from the glue outlet pipe 324 to the glue dispensing head 322. The glue dispensing head 322 applies the glue to the cardboard. When the cardboard leaves the gluing area, the glue dispensing head 322 stops dispensing glue, and the dripping glue falls back into the glue box 31 from the glue outlet 326.
