Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to a folding and sealing device for packaging cardboard boxes. Background Technology

[0002] Packaging carton folding and sealing devices have undergone a century of development, evolving from purely manual operation into intelligent equipment that integrates multiple disciplines such as mechanical design, electrical engineering, computer control, and artificial intelligence, effectively solving the pain points of efficiency, quality, and cost in traditional packaging;

[0003] In practical applications, the folding and sealing processes need to be separated into independent workstations. Step-by-step operations can easily lead to waiting between processes. This disconnect can result in cumulative efficiency losses in mass production scenarios, directly restricting the capacity release of high-speed packaging production lines. On the other hand, as a core component for storing tape and ensuring tape supply, the sealing box needs to be inspected and maintained regularly. However, the lack of a convenient maintenance structure makes each maintenance shutdown time-consuming, which directly disrupts the normal production rhythm, causing frequent production line stoppages and further aggravating the overall capacity loss. To address the above problems, the inventors have proposed a packaging carton folding and sealing device to solve these issues. Utility Model Content

[0004] To address the issues of integrated cardboard box folding and sealing and the lack of convenient maintenance for sealed boxes, this utility model aims to provide a cardboard box folding and sealing device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a packaging carton folding and sealing device, including an operating table, a carton folding and forming device is provided on one side of the operating table, a conveyor frame is provided on one side of the carton folding and forming device, a tape sealing device is provided between the carton folding and forming device and the conveyor frame, a fixing platform is provided on one side of the outer wall of the operating table, and a sealing self-locking positioning device is provided on the outer wall of the tape sealing device for quickly locking the device.

[0006] Preferably, the carton folding and forming device includes a stop cylinder, which is fixedly installed on the top of the operating table. A stop block is provided directly above the stop cylinder. A transmission rod is rotatably installed at both ends of the stop block. Two symmetrically distributed connecting rods are rotatably installed on the middle of the outer wall of each of the two transmission rods. The other ends of the two sets of connecting rods are rotatably connected to the two sides of the outer wall of the stop cylinder. A roller is rotatably installed at the other end of each of the two transmission rods. A sliding block is slidably installed inside the operating table near the stop cylinder. Two equally spaced transmission rods are rotatably installed inside the sliding block. The tops of the two transmission rods are... Each end is equipped with a rotatable roller. A first electric cylinder is fixedly installed inside the operating table. A connecting rod is fixedly installed at the output end of the first electric cylinder, and the connecting rod slides through the inside of the stop cylinder and is fixedly connected to the bottom of the stop block. A second electric cylinder is fixedly installed inside the operating table, and the output end of the second electric cylinder is fixedly connected to the outer wall of the sliding block. A guide groove is opened on the top of the operating table for sliding cooperation with the two rollers, and the bottom of the two rollers slides along the inner wall of the guide groove. A sliding groove is opened on the top of the operating table for sliding cooperation with the two transmission rods, and the two transmission rods slide along the inner wall of the sliding groove.

[0007] Preferably, the tape sealing device includes two sets of symmetrically distributed stop seats. Both sets of stop seats are fixedly installed inside the operating table. Guide blocks are slidably mounted on the top of both sets of stop seats. A bidirectional threaded rod is rotatably installed inside the two guide blocks at the end away from the conveyor frame through a threaded structure. The other end of the bidirectional threaded rod rotatably passes through the inside of the operating table. An adjustment knob is fixedly installed on the outer end of the bidirectional threaded rod.

[0008] Preferably, a cardboard box gripping robotic arm is slidably installed on one side of the top of the fixed platform to facilitate the gripping and placement of cardboard boxes, and a collection box is fixedly installed on the side of the fixed platform near the cardboard box gripping robotic arm for storing unprocessed boxes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model sets up a carton folding and forming device, which starts the first electric cylinder and drives two rollers to come together through the transmission rod to complete the folding of the wide side of the bottom of the carton. Then the carton is transferred to the top of the roller by the transport mechanism. The sensing device triggers the second electric cylinder, which causes the two rollers to come together along the guide groove to complete the folding in the length direction. When the folding and the conveying are pushed forward in sync, the tape sealing device seals the bottom of the carton at the same time. Through the above operation, the carton folding and sealing effect is achieved, which improves the production efficiency.

[0011] 2. This utility model, by setting a self-locking positioning device for sealing boxes, allows the device to slide to the preset installation position on the operating table. Rotating the adjustment knob in the forward direction drives the bidirectional threaded rod to rotate, which in turn drives the two guide blocks to slide relative to each other along the stop seat to clamp the device, thus achieving self-locking. Rotating the adjustment knob in the reverse direction causes the guide blocks to slide in the opposite direction to disengage from the clamp, completing the unlocking. Through the above operation, the effect of quickly unlocking the tape-sealed box is achieved, improving work efficiency. Attached Figure Description

[0023] 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.

[0024] like Figure 1-9 As shown, this utility model provides a packaging carton folding and sealing device, including an operating table 1. A carton folding and forming device 2 is provided on one side of the inside of the operating table 1. A conveyor frame 3 is provided on one side of the carton folding and forming device 2. A tape sealing device 4 is provided between the carton folding and forming device 2 and the conveyor frame 3. A fixed platform 5 is provided on one side of the outer wall of the operating table 1.

[0025] The carton folding and forming device 2 includes a stop cylinder 21, which is fixedly installed on the top of the operating table 1. A stop block 22 is provided directly above the stop cylinder 21. A transmission rod 23 is rotatably installed at both ends of the stop block 22. Two symmetrically distributed connecting rods 24 are rotatably installed in the middle of the outer wall of the two transmission rods 23. The other ends of the two sets of connecting rods 24 are rotatably connected to the two sides of the outer wall of the stop cylinder 21. Rollers 25 are rotatably installed at the other ends of the two transmission rods 23. A sliding block 27 is slidably installed inside the operating table 1 near the stop cylinder 21. Two equally spaced transmission rods 28 are rotatably installed inside the sliding block 27. Rollers 29 are rotatably installed at the top of the two transmission rods 28.

[0026] The outer wall of the tape sealing device 4 is equipped with a self-locking device 8 for quick locking of the device.

[0027] By adopting the above technical solution, the stop block 22 drives the transmission rods 23 on both sides to cooperate with the rollers 25 to first complete the folding of the wide side of the carton. Then, the two transmission rods 28 drive the two rollers 29 to fold the long side of the carton. During the conveying process, the tape sealing device 4 seals the bottom of the carton with glue, improving the consistency of the folding and the forming accuracy of the carton.

[0028] The tape sealing device 4 includes two sets of symmetrically distributed stop seats 81. Both sets of stop seats 81 are fixedly installed inside the operating table 1. Guide blocks 82 are slidably mounted on the top of both sets of stop seats 81. A bidirectional threaded rod 83 is rotatably installed through the threaded structure at one end of the two guide blocks 82 away from the conveyor frame 3. The other end of the bidirectional threaded rod 83 rotatably passes through the inside of the operating table 1. An adjustment knob 84 is fixedly installed at the outer end of the bidirectional threaded rod 83.

[0029] By adopting the above technical solution, rotating the bidirectional threaded rod 83 can adjust the displacement of the two guide blocks 82, preventing the tape from deviating from the carton seam during sealing, and further ensuring the consistency of the sealing position.

[0030] An electric cylinder 26 is fixedly installed inside the control panel 1. A connecting rod 212 is fixedly installed at the output end of the electric cylinder 26, and the connecting rod 212 slides through the inside of the stop cylinder 21 and is fixedly connected to the bottom of the stop block 22.

[0031] By adopting the above technical solution, the first electric cylinder 26 can drive the stop block 22 to slide vertically through the connecting rod 212, thereby driving the two rollers 25 to exert folding force on the paper box.

[0032] The second electric cylinder 213 is fixedly installed inside the control panel 1, and the output end of the second electric cylinder 213 is fixedly connected to the outer wall of the sliding block 27.

[0033] By adopting the above technical solution, the second electric cylinder 213 can drive the lateral displacement of the sliding block 27, thereby adjusting the sliding trajectory of the two rollers 29.

[0034] The top of the control panel 1 is provided with a guide groove 210 for sliding cooperation with two rollers 29, and the bottom of the two rollers 29 slides along the inner wall of the guide groove 210.

[0035] By adopting the above technical solution, the guide groove 210 provides a clear sliding trajectory constraint for the roller 29, avoiding left and right deviation of the roller 29.

[0036] The top of the control panel 1 is provided with a sliding groove 211 for sliding cooperation with two transmission rods 28, and the two transmission rods 28 slide along the inner wall of the sliding groove 211.

[0037] By adopting the above technical solution, the two transmission rods 28 slide along the inner wall of the sliding groove 211, which restricts the sliding direction of the two transmission rods 28 and prevents the transmission rods 28 from swaying left and right.

[0038] A paper box gripping robotic arm 6 is slidably installed on one side of the top of the fixed platform 5, which facilitates the gripping and placement of paper boxes.

[0039] By adopting the above technical solutions, the cardboard box gripping robotic arm 6 can complete the entire process of gripping, transferring, and placing cardboard boxes, greatly improving work efficiency.

[0040] A collection box 7 is fixedly installed on the side of the fixed platform 5 near the cardboard box gripping robotic arm 6, for storing unprocessed boxes.

[0041] By adopting the above technical solution, the collection box 7 provides a neat storage space for cardboard boxes, avoiding squeezing and deformation caused by random stacking of unfinished cardboard boxes, and ensuring the quality of finished product packaging.

[0042] Working principle: In actual application, the cardboard box gripping robot arm 6 first grips the unprocessed cardboard box from the collection box 7, smoothly transfers it and places it on the top of the operating table 1. Then, the cardboard box folding and forming device 2 is started to complete the folding and forming operation of the bottom of the cardboard box. During the folding and conveying of the cardboard box, the tape sealing device 4 simultaneously seals the bottom of the cardboard box. After sealing, the cardboard box is accurately transported to the designated position through the conveyor frame 3.

[0043] When it is necessary to fold and seal one side of the cardboard box, combine Figure 2 , Figure 3 and Figure 4 As shown, firstly, after the position sensing device detects that the cardboard box is in place, it transmits a signal to the first electric cylinder 26. The output end of the first electric cylinder 26 drives the stop block 22 to slide downward through the connecting rod 212, which in turn drives the transmission rods 23 at both ends to rotate closer to each other. During the rotation, the two rollers 25 are driven to move closer to each other, completing the folding and forming of the wide side of the bottom of the cardboard box. Subsequently, the cardboard box is transferred to the top of the two rollers 29 by the transport mechanism. At this time, the sensing device transmits a signal to the second electric cylinder 213. The output end of the second electric cylinder 213 drives the sliding block 27 to slide horizontally forward along the inside of the operating table 1, so that the two transmission rods 28 slide smoothly along the inner wall of the sliding groove 211. At the same time, the two rollers 29 are driven to move laterally closer to each other along the inner wall of the guide groove 210. During this process, the folding operation in the length direction of the cardboard box is completed. During the synchronous advancement of the cardboard box folding and conveying action, the tape sealing device 4 simultaneously seals the bottom of the cardboard box.

[0044] When self-locking of the tape sealing device is required, according to Figure 8 and Figure 9As shown, firstly, the tape sealing device is slidably assembled into the preset installation position inside the operating table 1. Then, a positive rotational force is applied to the adjusting knob 84. This force will synchronously drive the bidirectional threaded rod 83 to rotate along the inner wall of the operating table 1. Since the two guide blocks 82 and the bidirectional threaded rod 83 are connected by a threaded structure, when the bidirectional threaded rod 83 rotates, it drives the two guide blocks 82 to slide laterally relative to each other along the inner wall of the stop seat 81, thereby clamping the tape sealing device from both sides and completing the self-locking. When it is necessary to remove the tape sealing device, the adjusting knob 84 is rotated in the opposite direction, and the bidirectional threaded rod 83 rotates in the opposite direction. Through the threaded transmission, the two guide blocks 82 slide in the opposite direction along the guide surface at the top of the stop seat 81, gradually disengaging from the clamping contact with the tape sealing device, thus realizing the unlocking operation of the device.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
