Description

Technical Field

[0001] This utility model relates to the field of conveyor tape technology for laminating machines, specifically to an adjustment structure for conveyor tape of an automatic packaging box laminating machine. Background Technology

[0002] The conveyor belt of the automatic packaging box laminating machine specifically refers to the ring-shaped belt transmission component used in the equipment to accurately, synchronously and stably transport the packaging box substrate through various work stations, such as gluing, laminating and compaction stations. The conveyor belt includes a bottom conveyor belt for transporting the substrate and a side conveyor belt for restricting the substrate.

[0003] The automatic packaging box laminating machine lacks a conveyor belt adjustment structure, which can easily cause packaging boxes and other substrates to slip or shift during transportation, making it impossible to accurately reach the preset laminating position. This makes it difficult for the equipment to maintain a stable conveying state, resulting in large fluctuations in product quality and seriously affecting production efficiency and stability. Utility Model Content

[0004] The purpose of this utility model is to provide a conveyor tape adjustment structure for an automatic packaging box laminating machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustment structure for conveying tape in an automatic packaging box laminating machine, comprising a laminating machine conveying mechanism, a support platform, and a support plate. The support platform is bolted to one side of the outer wall of the laminating machine conveying mechanism, and a support plate is connected to the top of the outer wall of the support platform. A fixing pin is welded to one side of the bottom end of the support plate, and a base is rotatably connected to the outer wall of the fixing pin. An inclined plate is welded to one side of the top end of the base, and a conveying wheel is connected to both the inclined plate and the outer wall of the base. A conveying tape body is rotatably connected to the outer wall of the conveying wheel, and the conveying wheel is used to guide and restrict the movement of the conveying tape body.

[0006] A support rod is threadedly connected to the middle of the inclined plate, and the bottom end of the support rod penetrates the base. A pin is threadedly connected to the inner wall of the conveyor wheel, and a bolt is threadedly connected to one side of the pin. The pin is used to restrict the rotation of the conveyor wheel.

[0007] The support plate has an arc groove inside its top end, and an extension pin is connected inside the arc groove. One side of the outer wall of the extension pin is welded to the base, and a nut is threaded to the other side of the outer wall of the extension pin. The arc groove is used to guide the base to rotate, and the nut is used to fix the base after rotation.

[0008] By rotating the No. 1 nut to disengage from the support plate, the restriction on the base is removed. The base is then pushed to rotate around the fixed pin. At this time, the extension pin moves along the arc groove, guiding the base to rotate smoothly until the base drives the transmission wheel to rotate to the specified angle.

[0009] Preferably, a straight groove is formed inside the bottom end of the support plate on the side away from the fixing pin, and a fixing groove corresponding to the straight groove is formed at the top of the support platform. Threaded pins are connected to both sides inside the straight groove, and the threaded pins pass through the fixing groove.

[0010] Turn the No. 2 nut downwards along the threaded pin to remove the limit on the support plate, then push the support plate to move it along the top surface of the support platform, thereby adjusting the horizontal position of the support plate.

[0011] Preferably, a washer is fitted onto the outer wall of the top of the threaded pin, and a No. 2 nut is threadedly connected to the bottom of the outer wall of the threaded pin, and the top of the outer wall of the No. 2 nut is tightly fitted to the support platform.

[0012] Rotate the No. 2 nut upwards along the threaded pin until it fits tightly against the support plate, thus restricting the support plate and preventing it from moving further.

[0013] Preferably, the outer wall of the bonding machine conveying mechanism is bolted to a mounting plate on the side near the support platform. A fixed wheel is connected to the bottom middle part of the mounting plate, and a limit seat is welded to the top middle part of the mounting plate. A threaded rod is threadedly connected inside the limit seat.

[0014] After the mounting plate is fixed to the side of the laminating machine's conveyor mechanism with bolts, the main body of the conveyor belt moves past the fixed wheel and the tensioning wheel. At this time, the tensioning wheel and the fixed wheel, together with the conveyor wheel, restrict the movement of the main body of the conveyor belt.

[0015] Preferably, a mounting base is rotatably connected to one side of the outer wall of the threaded rod, and a tensioning wheel is fixedly connected to the middle of the outer wall of the mounting base. A spring is sleeved on the middle of the outer wall of the threaded rod, and a spring is fixedly connected to one side of the outer wall of the mounting base.

[0016] By rotating the threaded rod inside the limit seat, the movement of the threaded rod will cause the mounting seat to move synchronously, thereby adjusting the linear distance between the fixed wheel and the tensioning wheel, so that the conveyor belt body is always in a taut position.

[0017] Preferably, one side of the outer wall of the spring is fixedly connected to the limiting seat, and the other side of the outer wall of the spring is fixedly connected to the mounting seat. The limiting seat, the threaded rod, the mounting seat, and the spring constitute an elastic telescopic mechanism.

[0018] The movement of the mounting base compresses the spring, causing it to deform. The spring then returns to its original position, assisting the mounting base in driving the tension wheel back into place.

[0019] Preferably, a slider is fixedly connected to the outer wall of the mounting base near the mounting plate, and the slider has a "T" shaped structure. The mounting plate has a groove inside that corresponds to the slider, which is used to guide the tensioning wheel to move linearly.

[0020] The slider slides along the groove, guiding the mounting base to move smoothly in a straight line until the mounting base drives the tension wheel to the designated position.

[0021] As can be seen from the above, the conveyor tape adjustment structure of the automatic packaging box bonding machine provided by this utility model has the following beneficial effects.

[0022] By breaking down complex spatial adjustments into simple rotation and translation operations through modular design, the debugging and maintenance process is greatly simplified. The tilt angle and horizontal coordinates of the conveyor wheels can be adjusted independently or in combination, achieving precise control of the conveying path and realizing multi-degree-of-freedom precision control. This allows engineers to finely optimize the wrap angle, tension, and trajectory of the conveyor belt, effectively preventing deviations and slippage at the source, ensuring extremely high precision in material conveying. Furthermore, the pre-fold angle of the product's pressure lines can be precisely adjusted according to product requirements, improving the product's bonding strength.

[0023] By adjusting the center distance between the fixed wheel and the tensioning wheel, the conveyor belt body is ensured to always be in a preset tension state, fundamentally preventing the conveyor belt from loosening. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-11 This utility model provides a technical solution: an adjustment structure for conveying tape in an automatic packaging box laminating machine, including a laminating machine conveying mechanism 1, a support platform 2, and a support plate 3. The support platform 2 is bolted to one side of the outer wall of the laminating machine conveying mechanism 1, and the support plate 3 is connected to the top of the outer wall of the support platform 2. A fixing pin 4 is welded to one side of the bottom end of the support plate 3, and a base 5 is rotatably connected to the outer wall of the fixing pin 4. An inclined plate 6 is welded to one side of the top end of the base 5, and both the inclined plate 6 and the outer wall of the base 5 are connected to a conveying wheel 7. The outer wall of the conveying wheel 7 is rotatably connected to the conveying tape body 8, and the conveying wheel 7 is used to guide and restrict the movement of the conveying tape body 8.

[0038] A support rod 10 is threadedly connected to the middle of the inclined plate 6, and the bottom end of the support rod 10 passes through the base 5. A pin 9 is threadedly connected to the inner wall of the conveyor wheel 7, and a bolt is threadedly connected to one side of the pin 9. The pin 9 is used to restrict the rotation of the conveyor wheel 7.

[0039] The support plate 3 has an arc groove 11 inside the top end, and an extension pin 12 is connected inside the arc groove 11. One side of the outer wall of the extension pin 12 is welded to the base 5, and the other side of the outer wall of the extension pin 12 is threaded with a nut 13. The arc groove 11 is used to guide the base 5 to rotate, and the nut 13 is used to fix the base 5 after rotation.

[0040] A straight groove 14 is provided inside the bottom end of the support plate 3 on the side away from the fixing pin 4, and a fixing groove corresponding to the straight groove 14 is provided at the top of the support platform 2. Threaded pins 15 are connected to both sides inside the straight groove 14, and the threaded pins 15 pass through the fixing groove. A washer 16 is sleeved on the outer wall of the top of the threaded pin 15, and a second nut 17 is threadedly connected to the bottom of the outer wall of the threaded pin 15, and the top of the outer wall of the second nut 17 is tightly fitted to the support platform 2.

[0041] In practice, the operator places the pre-cut packaging box and printed face paper into the machine's rack. The machine uses a precise glue spraying system to evenly apply glue to the bonding surface of the packaging box. At this time, a robotic arm or vacuum suction cup picks up the face paper and positions it precisely. Simultaneously, the laminating machine's conveyor mechanism 1 delivers the gray board to the laminating station. Then, through specific molds and mechanisms, the face paper is tightly and smoothly wrapped onto the gray board according to the preset folding sequence and pressure. During this process, the conveyor belt on the side of the laminating machine's conveyor mechanism 1, in conjunction with the conveyor belt, guides the packaging box to the designated position. Next, the laminated box enters the compaction zone, where rollers or pressure plates apply uniform pressure to ensure that the face paper and gray board are completely bonded, without bubbles or wrinkles. Finally, the finished laminated box is automatically output for stacking or proceeding to the next process.

[0042] See Figure 2 and Figure 3 The support rod 10 provides auxiliary support for the inclined plate 6, effectively enhancing its connection rigidity with the base 5 and ensuring the stability of the overall structure. When the conveyor belt body 8 passes around the conveyor wheel 7, the conveyor wheel 7 rotates with low resistance around the pin 9, thereby precisely guiding and constraining the running trajectory of the conveyor belt body 8, and finally reliably transporting the packaging box to the designated workstation;

[0043] See Figure 5 , Figure 6 and Figure 7 Loosen the No. 1 nut 13 to disengage it from the support plate 3, releasing the axial constraint on the base 5. Then, push the base 5 to rotate around the fixing pin 4. At this time, the extension pin 12 moves synchronously along the arc groove 11. After the base 5 drives the transmission wheel 7 to rotate to the target angle, tighten the No. 1 nut 13 again to press it tightly against the outer wall of the support plate 3, thereby locking the base 5 and preventing it from rotating.

[0044] Unscrew the No. 2 nut 17 to release its clamping force on the support plate 3. Then move the support plate 3 horizontally along the top surface of the support platform 2 to adjust its horizontal position. After the support plate 3 moves to the target position, ensure that the threaded pin 15 passes through the straight groove 14 and that the washer 16 is in contact with the surface of the support plate 3. Then screw on the No. 2 nut 17 to press it against the support platform 2, thereby firmly locking the support plate 3.

[0045] The tilt angle and horizontal coordinate of the conveyor wheel 7 can be adjusted independently or in combination through the above operations, achieving precise control of the conveying path and realizing precise control of multiple degrees of freedom. This allows engineers to finely optimize the wrap angle, tension, and running trajectory of the conveyor belt body 8, effectively preventing phenomena such as deviation and slippage from the source, ensuring extremely high precision in material conveying. Furthermore, the modular design breaks down complex spatial position adjustments into simple rotation and translation operations, greatly simplifying the debugging and maintenance process.

[0046] See Figure 4 , Figure 10 and Figure 11 A mounting plate 18 is bolted to the side of the outer wall of the laminating machine conveying mechanism 1 near the support platform 2. A fixed wheel 19 is connected to the bottom of the middle part of the mounting plate 18, and a limit seat 20 is welded to the top of the middle part of the mounting plate 18. A threaded rod 21 is threadedly connected inside the limit seat 20. A mounting seat 22 is rotatably connected to one side of the outer wall of the threaded rod 21, and a tension wheel 23 is fixedly connected to the middle of the outer wall of the mounting seat 22. A spring 24 is sleeved on the middle of the outer wall of the threaded rod 21. A fixed spring 24 is fixed to one side of the outer wall of the mounting seat 22. A spring 24 is connected; one side of the outer wall of the spring 24 is fixedly connected to the limiting seat 20, and the other side of the outer wall of the spring 24 is fixedly connected to the mounting seat 22. The limiting seat 20, the threaded rod 21, the mounting seat 22 and the spring 24 form an elastic telescopic mechanism; a slider 25 is fixedly connected to the outer wall of the mounting seat 22 near the mounting plate 18, and the slider 25 has a "T" shaped structure. The mounting plate 18 has a groove inside that corresponds to the slider 25, which is used to guide the tensioning wheel 23 to move linearly.

[0047] In practice, the conveyor belt body 8 is securely mounted to the side of the laminating machine conveyor mechanism 1 by bolts through the mounting plate 18. During installation, the conveyor belt body 8 is sequentially wound around the fixed wheel 19 and the tension wheel 23. Thus, the tension wheel 23 and the fixed wheel 19, together with the conveyor wheel 7, form a closed transmission path, precisely guiding and constraining the running trajectory of the conveyor belt body 8.

[0048] When the conveyor belt body 8 becomes slack, the threaded rod 21 inside the rotating limit seat 20 is converted into the linear motion of the mounting seat 22. During this process, the guide formed by the slider 25 and the groove ensures that the mounting seat 22 moves smoothly along the predetermined trajectory without deviation or jamming. The mounting seat 22 moves outward, directly driving the tensioning wheel 23 to move until it reaches the target position that can effectively tension the belt. This movement process compresses the spring 24, allowing it to accumulate elastic potential energy. The spring 24 plays a role in continuously applying tension and automatic compensation in the system. When the belt may subsequently elongate slightly, the restoring force of the spring 24 will push the mounting seat 22, assisting the tensioning wheel 23 to automatically fine-tune and return to its original position, thereby dynamically maintaining a constant tension.

[0049] By adjusting the center distance between the fixed wheel 19 and the tensioning wheel 23, the conveyor belt body 8 is always kept in a preset taut state, thus fundamentally preventing the conveyor belt from loosening.

[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
