[0001] This utility model relates to the field of packaging machinery technology, and in particular to a sealing device for carton production. Background Technology

[0002] With the rapid development of the e-commerce industry and the continuous growth in logistics and transportation demands, cardboard boxes, as important packaging containers, directly impact the safety of goods transportation and the operating costs of enterprises due to their production efficiency and sealing quality. Cardboard box sealing devices, as key equipment in the production line, undertake the important task of quickly and stably sealing cardboard boxes. They are widely used in various packaging production workshops, becoming an indispensable tool for improving packaging efficiency and quality.

[0003] However, existing carton sealing devices have many limitations in practical applications. On the one hand, most devices are difficult to adapt flexibly to different sizes of cartons and cannot achieve width adjustment and positioning fixation of the conveyor channel, causing cartons to easily shift during sealing, affecting sealing effect and production efficiency. On the other hand, the tape replacement process of traditional sealing devices is cumbersome. When the tape runs out, operators need to spend a lot of time disassembling and installing the tape, which restricts the continuity of sealing work and the improvement of production efficiency. Therefore, a carton sealing device for carton production is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sealing device for carton production, which aims to improve the problems of existing technology that cannot adapt to different specifications of cartons and the cumbersome tape replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carton sealing device for carton production includes a workbench, a motor fixedly connected to the top of the workbench, a drive wheel fixedly connected to the output end of the motor, multiple support legs fixedly connected to the top of the workbench, a shelf fixedly connected to the top of the support legs, a fixing mechanism on the top of the shelf, a fixed column rotatably connected to the top of the shelf, a driven wheel fixedly connected to the outside of the fixed column, a rotating rod fixedly connected to the outside of the fixed column, a conveying device fixedly connected to the top of the shelf, a U-shaped column fixedly connected to the top of the conveying device, a tape applicator fixedly connected to the inside of the U-shaped column, a support plate fixedly connected to the top of the tape applicator, a sleeve fixedly connected inside the support plate, a core sleeved on the outside of the sleeve, adhesive tape on the outside of the core, and a quick-release mechanism inside the sleeve.

[0007] The fixing mechanism includes two guide rails. The bottom of the guide rails is fixedly connected to the top of the shelf. Two sliders are slidably connected to the outer side of each guide rail. A slide plate is fixedly connected to the top of each slider. Multiple rotating columns are provided inside the slide plate. A connecting seat is fixedly connected to the opposite side of each of the two sliders.

[0008] As a further description of the above technical solution:

[0009] The quick-release mechanism includes a pull rod, the outer side of which is slidably connected to the inside of a sleeve, a spring is sleeved on the outer side of the pull rod, a fixing block is fixedly connected to the outer side of the pull rod, connecting rods are rotatably connected to both sides of the fixing block, and a locking block is rotatably connected to the end of the connecting rod away from the fixing block;

[0010] As a further description of the above technical solution:

[0011] The outer side of the sliding plate is slidably connected to the inside of the conveying device, and the outer side of the slider is slidably connected to the inside of the conveying device;

[0012] As a further description of the above technical solution:

[0013] One end of the rotating rod is rotatably connected to the top of one of the connecting seats, and the other end of the rotating rod is rotatably connected to the top of another connecting seat;

[0014] As a further description of the above technical solution:

[0015] The driving wheel and the driven wheel mesh with each other, and the bottom of the worktable is provided with casters;

[0016] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The fixing block is slidably connected inside the sleeve, and a pull ring is fixedly connected to the end of the pull rod away from the locking block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when a carton needs to be sealed, the sliding plate is driven to move laterally through the sliding cooperation structure of the guide rail and the slider, thereby fixing and positioning the carton. At the same time, the conveyor column, the rotating column, and the tape applicator cooperate with each other to ensure stable sealing of the carton. This realizes the adjustment, positioning, and stable sealing of the conveyor width of cartons of different specifications, thus facilitating the sealing of cartons of different specifications.

[0024] 2. In this utility model, when the tape is used up, pulling the pull ring drives the connecting rod to move, which in turn moves the fixing block and causes the locking block to slide into the sleeve. After the locking block is inserted into the sleeve, the tape is taken out, and a new tape is put on the outside of the sleeve. Then, the pull ring is released, and the spring squeezes the fixing block, which drives the connecting rod to move and causes the locking block to gradually extend out of the sleeve, so that the core rotates stably on the sleeve. This achieves quick tape removal and improves the working efficiency of the carton sealing device in carton production. Attached Figure Description

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.

[0034] Reference Figures 1-6 A carton sealing device for carton production includes a workbench 1, a motor 2 fixedly connected to the top of the workbench 1, a drive wheel 16 fixedly connected to the output end of the motor 2, multiple support legs 3 fixedly connected to the top of the workbench 1, a shelf 4 fixedly connected to the top of the support legs 3, a fixing mechanism on the top of the shelf 4, a fixed column 18 rotatably connected to the top of the shelf 4, a driven wheel 15 fixedly connected to the outside of the fixed column 18, a rotating rod 17 fixedly connected to the outside of the fixed column 18, a conveying device 5 fixedly connected to the top of the shelf 4, a U-shaped column 8 fixedly connected to the top of the conveying device 5, a tape applicator 9 fixedly connected to the inside of the U-shaped column 8, a support plate 11 fixedly connected to the top of the tape applicator 9, a sleeve 21 fixedly connected inside the support plate 11, a core 23 sleeved on the outside of the sleeve 21, adhesive tape 10 disposed on the outside of the core 23, and a quick-release mechanism disposed inside the sleeve 21.

[0035] The fixing mechanism includes two guide rails 14. The bottom of the guide rails 14 is fixedly connected to the top of the shelf 4. Two sliders 19 are slidably connected to the outer side of each guide rail 14. A slide plate 7 is fixedly connected to the top of each slider 19. Multiple rotating columns 12 are provided inside the slide plate 7. A connecting seat 20 is fixedly connected to the opposite side of each slider 19. The outer side of the slide plate 7 is slidably connected to the inside of the conveying device 5. The outer side of the slider 19 is slidably connected to the inside of the conveying device 5. One end of the rotating rod 17 is rotatably connected to the top of one connecting seat 20, and the other end of the rotating rod 17 is rotatably connected to the top of another connecting seat 20. The driving wheel 16 and the driven wheel 15 mesh with each other. Universal wheels are provided at the bottom of the worktable 1.

[0036] Workbench 1 provides basic support for the entire device. The casters have a self-locking function, facilitating the movement of the sealing device to the desired sealing position. Motor 2 provides power to the fixing mechanism. Support legs 3 support the shelf 4, which is used to mount the fixing mechanism and conveyor 5. Conveyor 5 transports the cartons to be sealed to the fixing mechanism and also supports the U-shaped column 8. Slide plate 7 clamps the cartons and works with the tape applicator 9 to adjust the sealing position. U-shaped column 8 fixes the tape applicator 9, ensuring stable tape application. The tape applicator 9 has a cutter and pressure roller inside, used to cut the tape 10 and ensure contact between the tape 10 and the carton. The tape 10 is the sealing material. Support plate 11 fixes the sleeve 21, ensuring stable operation of the quick-release mechanism. Rotating column 12 assists in carton movement. Rotating column 12, conveyor 5, and tape applicator 9 work together to ensure stable sealing of the cartons. Guide rail 14 is fixed. The fixed slider 19 provides motion guidance. The driven wheel 15 and the driving wheel 16 work together to transmit the power of the motor 2 to the fixing mechanism, preventing the motor 2 from rotating too fast and damaging the carton. The use of the driven wheel 15 and the driving wheel 16 can effectively reduce the clamping speed of the fixing mechanism and avoid damage to the carton. The rotating rod 17 is used to convert the rotational motion of the motor 2 into the linear motion of the slider 19. The fixed column 18 is used to fix the driven wheel 15 and the rotating rod 17 and allow the driven wheel 15 and the rotating rod 17 to rotate around it. The slider 19 is used to fix the slide plate 7 and cooperate with the guide rail 14. Sliding along the guide rail 14 moves the slide plate 7, realizing the adjustment of the position of the slide plate 7 relative to the carton. The connecting seat 20 is used to fix the rotating rod 17 to ensure the relative position stability of the slider 19. The sleeve 21 is used to provide an installation place for the tape 10 and the core 23, and to provide a movement place for the fixing block 6, the spring 13, the locking block 22 and the connecting rod 25. The core 23 is used to fix the tape 10.

[0037] Reference Figure 6 and Figure 7 The quick-release mechanism includes a pull rod 24, which is slidably connected to the inside of a sleeve 21. A spring 13 is sleeved on the outside of the pull rod 24. A fixing block 6 is fixedly connected to the outside of the pull rod 24. A connecting rod 25 is rotatably connected to both sides of the fixing block 6. A locking block 22 is rotatably connected to the end of the connecting rod 25 away from the fixing block 6. The locking block 22 is slidably connected to the inside of the sleeve 21. One end of the spring 13 is fixedly connected to one side of the fixing block 6. The other end of the spring 13 abuts against the inner wall of the sleeve 21. The fixing block 6 is slidably connected to the inside of the sleeve 21. A pull ring is fixedly connected to the end of the pull rod 24 away from the locking block 22.

[0038] The fixing block 6 is used to transmit the elastic force of the spring 13 to the connecting rod 25 and the pull rod 24. The spring 13 is used to ensure that the core 23 of both rotates stably on the outside of the sleeve 21 under the action of the locking block 22 without external force, so that the tape 10 can rotate stably. The locking block 22 makes the core 23 rotate stably on the outside of the sleeve 21. The pull rod 24 is used to fix the fixing block 6, the spring 13, and the connecting rod 25 and to provide the movement trajectory for the spring 13. The connecting rod 25 is used to fix the locking block 22, so that the locking block 22 is firmly fixed on the outside of the sleeve 21. The pull ring makes it convenient for the operator to pull the pull rod 24, thereby facilitating the replacement of the tape 10.

[0039] Working principle: When it is necessary to seal a carton, the production sealing device is moved to the position where the carton needs to be sealed by the casters of the workbench 1 and the casters are locked. The carton is transported to the fixing mechanism by the conveyor 5. The motor 2 is started to drive the drive wheel 16, which drives the driven wheel 15 to rotate through gear meshing. This drives the fixed column 18 to rotate, causing the rotating rod 17 to rotate. This causes the slider 19 to move on the guide rail 14, thereby adjusting the two sliding plates 7 to gradually approach each other and thus positioning and clamping the carton. At the same time, the conveyor 5, the rotating column 12 and the tape applicator 9 cooperate with each other to ensure stable sealing of the carton. When tape 10 runs out and needs to be replaced, pulling the pull ring drives the connecting rod 25 via the pull rod 24, which in turn moves the fixing block 6, causing the locking block 22 to slide into the sleeve 21 until the core 23 can be removed from the sleeve 21. Then, the tape 10 is removed, and a new tape 10 is re-attached to the outside of the sleeve 21. After releasing the pull ring, the spring 13 is no longer subjected to external force, which compresses the fixing block 6 and drives the connecting rod 25 to move. The locking block 22 gradually extends out from the inside of the sleeve 21, allowing the core 23 to rotate stably on the outside of the sleeve 21. This enables the tape 10 to be quickly disassembled and replaced, improving the working efficiency of the carton sealing device used in carton production.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
