Description

Technical Field

[0001] This utility model relates to the technical field of tape sealing machines, specifically a tape sealing machine for packaging boxes. Background Technology

[0002] A tape sealing machine is a device used to seal items such as cartons and bags, and is widely used in the packaging industry. It works by heating and melting adhesive tape, which then adheres to the item, thus achieving the sealing purpose.

[0003] Patent CN219904946U discloses a tape sealing machine for packaging boxes. It includes a conveyor and a tape sealer welded above the conveyor. Two sets of guide strips are arranged in the middle of the conveyor and below the tape sealer. Each set of guide strips has a floating guide structure inside. The distance between the guide strips can be floating. When the folded packaging box has size errors, it can pass through the space between the guide strips. This ensures that the heavier packaging box is located between the guide strips, thereby ensuring that the tape of the tape sealer is aligned with the sealing edge of the packaging box. This prevents the packaging box from deviating from the central axis of the tape sealer, which would cause uneven tape adhesion.

[0004] However, this device has a problem because both guide bars are placed flat. This means that when the packaging box is placed on the conveyor belt, it must be placed on the conveyor belt without shifting in order to ensure that the packaging box is transported between the two guide bars. If the packaging box shifts, it is difficult to ensure that the packaging box is transported between the two guide bars for limited transmission, thus making it impossible to seal. To address this issue, a tape sealing machine for packaging boxes is proposed to solve the problem that existing sealing machines cannot stably and accurately transport packaging boxes for sealing.

[0015] (III) Beneficial Effects

[0016] 1. The tape sealing machine for this packaging box adjusts the distance between the two guide limit seats to match the packaging box to be sealed by adjusting the mechanism. Then, the conveyor belt in the groove is turned on, and the packaging box is placed on the conveyor belt. The electric push rod connected to the second rotating shaft in the U-shaped seat drives the control board and the rotating plate to rotate 90 degrees. This pushes the packaging box from both ends to be parallel to the conveyor belt and to make the packaging box face the guide limit seats. This solves the problem that existing sealing machines are difficult to stably and accurately convey packaging boxes for sealing.

[0017] 2. The tape sealing machine for this packaging box uses a dual-axis motor to drive the adjusting screw to rotate. Under the action of the L-shaped adjusting plate in the adjusting groove, the guide limit seat is adjusted. The distance of the guide limit seat adjustment is precisely controlled by the scale, so that the distance between the two guide limit seats is suitable for limiting the size of the packaging box being conveyed, thereby improving the applicability of the tape sealing machine and the stability of the packaging box during the conveying process.

[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] Example: Please refer to Figure 1-4A tape sealing machine for packaging boxes includes a workbench 1, with electric lifting frames 2 symmetrically arranged on the top of the workbench 1, and a tape sealer 3 arranged between the two electric lifting frames 2. Guide limit seats 4 are symmetrically arranged on the top of the workbench 1, and adjustment mechanisms 5 are arranged on both sides of the workbench 1. A rotating plate 6 is rotatably connected to one side of the guide limit seat 4, and the rotating plate 6 is connected to the guide limit seat 4 through a first rotating shaft 12. A control plate 7 is fixedly connected to one end of the rotating plate 6. A groove 8 is opened on the top of the workbench 1, and a conveyor belt 9 is arranged in the inner cavity of the groove 8. A U-shaped seat 10 is fixedly connected to one end of both the guide limit seat 4 and the control plate 7. An electric push rod 11 is rotatably arranged in the inner cavity of the U-shaped seat 10 on the control plate 7, and the electric push rod 11 is rotatably arranged in the inner cavity of the U-shaped seat 10 through a second rotating shaft 13.

[0025] Furthermore, the conveyor belt 9 is driven by an external drive device, and the movable end of the electric push rod 11 is rotatably connected to the guide limit seat 4 through the second rotating shaft 13.

[0026] Furthermore, when the rotating plate 6 is in its initial position, the angle between it and the conveyor belt 9 is 30 degrees, and the angle between the control plate 7 and the rotating plate 6 is 90 degrees.

[0027] Furthermore, the adjustment mechanism 5 includes adjustment grooves 501 at both ends of the worktable 1, and an L-shaped adjustment plate 502 is slidably arranged in the inner cavity of the adjustment groove 501. The L-shaped adjustment plate 502 is fixedly connected to the guide limit seat 4.

[0028] Furthermore, scales 503 are provided on both sides of the top of the workbench 1, and a dual-axis motor 504 is fixedly connected to the bottom of the workbench 1. Adjusting screws 505 are fixedly connected to the output shafts at both ends of the dual-axis motor 504. The adjusting screws 505 pass through the L-shaped adjusting plate 502 and the two are threaded together.

[0029] Furthermore, when the guide limit seat 4 is in the initial position, the zero mark of the scale 503 is aligned with the front end of the L-shaped adjustment plate 502. When the guide limit seat 4 is in the initial position, the distance between them is known. The dual-axis motor 504 drives the adjusting screw 505 to rotate, and then, under the action of the L-shaped adjustment plate 502 in the adjusting groove 501, the guide limit seat 4 is adjusted. In conjunction with the scale 503, the distance of the guide limit seat 4 is precisely controlled, so that the distance between the two guide limit seats 4 is suitable for limiting the size of the packaged box being conveyed, thereby improving the applicability of the tape sealing machine for this packaged box and the stability of the packaged box during the conveying process.

[0030] Furthermore, each of the opposite ends of the guide limit seat 4 is provided with a second groove 14. A guide roller 15 is rotatably arranged in the inner cavity of the second groove 14. The outer ring of the guide roller 15 extends out of the second groove 14 and the extension length is known. When the rotating plate 6 rotates to be parallel with the conveyor belt 9, the end faces of the rotating plate 6 and the guide roller 15 are located in the same plane. The sliding friction between the packaging box and the guide limit seat 4 is transformed into rolling friction by the guide roller 15 in the second groove 14, ensuring a smoother conveying process for the packaging box.

[0031] Working principle: When using this tape sealing machine for packaging boxes, the distance between the two guide limit seats 4 is adjusted by the adjusting mechanism 5 to match the packaging box to be sealed. Then, the conveyor belt 9 in the groove 8 is opened, and the packaging box is placed on the conveyor belt 9. The electric push rod 11, which is rotatably connected by the second rotating shaft 13 in the U-shaped seat 10, drives the control plate 7 and the rotating plate 6 to rotate 90 degrees. This pushes the packaging box from both ends to be parallel to the conveyor belt 9 and to make the packaging box face the guide limit seats 4. This solves the problem that existing sealing machines are difficult to stably and accurately transport packaging boxes for sealing. When the packaging box is stably limited by the guide limit seats 4 and transported to the tape sealer 3, the height of the tape sealer 3 can be adjusted by the electric lifting frame 2 to perform the sealing operation on the packaging box.
