Abstract
Description
Technical Field
[0001] This utility model particularly relates to an automatic pressing device for flexible sheets at the corners of cardboard boxes. Background Technology
[0002] In the cardboard packaging industry, the corner strength of a cardboard box is crucial. A cardboard box corner consists of a first surface and a second surface, which are adjacent and form a transition corner. The current reinforcement process involves workers manually applying one side of adhesive tape to the first surface, then manually folding the remaining tape and bonding it to the second surface. However, manual operation has many drawbacks: firstly, manually folding the tape makes it difficult to ensure precise folding angles each time, easily resulting in wrinkles and skewing; secondly, uneven application pressure can lead to weak adhesion between the tape and the cardboard box, affecting the overall strength and appearance of the box. Furthermore, manual operation is slow, failing to meet the high-efficiency requirements of large-scale production lines, and has become a key factor restricting the speed of the packaging process.

The pushing mechanism 1 is provided with a pushing member 3 that can move up and down. The carton is defined with a first surface 4 and a second surface 5, which are arranged adjacent to each other and form a transition corner between the two surfaces. The pushing mechanism 1 is used to fold and push the unbonded portion of the flexible sheet material 6 that has been partially bonded to the first surface 4 of the carton to the adjacent second surface 5. The rolling mechanism 2 is used to roll and bond the pushed flexible sheet material 6.
[0026] Preferably, the pushing mechanism 1 includes a first driving device 11 disposed on the conveyor frame, a mounting bracket 12 connected to the first driving device 11, and the pushing member 3 is mounted on the mounting bracket 12. The working surface of the pushing member 3 is parallel to the second surface 5 of the carton.
[0027] Preferably, the mounting bracket 12 has a mounting groove 121 at its bottom, and the pusher 3 has a connecting part 122 that mates with the mounting groove 121; the connecting part 122 and the mounting groove 121 are fixed together by bolts.

[0029] Preferably, the turntable 21 has a plurality of mounting positions 211 evenly distributed on its circumferential edge, and each mounting position 211 is equipped with a positioning block 22; the bristles 23 on adjacent positioning blocks 22 are staggered in the circumferential direction of the turntable 21.
[0030] Preferably, the flexible sheet 6 is adhesive tape.
[0031] Preferably, the conveyor frame is fixedly provided with a mounting bracket 7 for installing the pushing mechanism 1 and the rolling mechanism 2.
[0032] The working principle of this utility model is as follows:
[0033] The automatic pressing device for the flexible sheet 6 at the corner of the carton in this embodiment includes a pushing mechanism 1 and a rolling mechanism 2 arranged sequentially along the conveyor frame. The pushing mechanism 1 is used to fold the unbonded portion of the flexible sheet 6 on the first surface 4 of the carton and push it to the adjacent second surface 5. The rolling mechanism 2 is used to roll and bond the pushed flexible sheet 6. The flexible sheet 6 can be made of adhesive tape.
[0034] As in Embodiment 1, the pressing mechanism 1 may include a first driving device 11 mounted on a conveyor frame. A mounting bracket 12 is connected to the first driving device 11, and a pressing member 3 is mounted on the mounting bracket 12. A mounting groove 121 is provided at the bottom of the mounting bracket 12, and a connecting part 122 that mates with the mounting groove 121 is provided on the pressing member 3. The connecting part 122 is fixed to the mounting groove 121 by bolts, thereby achieving stable installation of the pressing member 3 and ensuring that the flexible sheet 6 can be accurately pressed onto the second surface 5.
[0035] Based on the above technical solution, the rolling mechanism 2 includes a turntable 21 rotatably mounted on a conveyor frame. Multiple positioning blocks 22 are evenly distributed on the turntable 21, and each positioning block 22 is equipped with bristles 23. The turntable 21 is connected to a rotary motor, which drives the turntable 21 to rotate, allowing the bristles 23 to roll and bond the pressed flexible sheet 6. The bristles 23 on adjacent positioning blocks 22 are staggered around the circumference of the turntable 21 to ensure that the bristles 23 can evenly contact the flexible sheet 6, thereby improving the bonding quality of the flexible sheet 6.
[0036] Work process
[0037] In the initial state, such as Figure 3 As shown, one side of the flexible sheet 6 is bonded to the first surface 4 of the carton. The carton then moves on the conveyor frame. When the carton reaches the position of the pushing mechanism 1, the first drive device 11 drives the mounting bracket 12 to move, causing the pushing member 3 to move up and down, folding the unbonded portion of the flexible sheet 6 from the first surface 4 and pushing it to the second surface 5, so that the flexible sheet 6 can be bonded to the second surface 5. Figure 4 As shown. Subsequently, the carton continues to move to the position of the rolling mechanism 2. The turntable 21 rotates under the drive of the rotary motor, which drives the positioning block 22 on the turntable 21 to rotate. The brush 23 rolls and presses the already pressed flexible sheet 6, finally completing the pressing work of the flexible sheet 6 at the corner of the carton.
[0038] Traditional methods of applying adhesive tape to cardboard corners rely on manual operation, which is slow and difficult to meet the needs of continuous production. This device automates the process, with the cardboard box undergoing tape pushing, folding, and rolling during transport, eliminating the need for manual intervention. This significantly reduces the processing time for individual boxes and shortens the production cycle. Furthermore, the pushing mechanism 1 precisely presses the unbonded portion of the tape onto the second surface 5, ensuring accurate tape folding angles. The rolling mechanism 2 applies even pressure through the brush 23, ensuring the tape adheres tightly to the cardboard corners, effectively preventing wrinkles and skewing, reducing the risk of damage due to loose tape, improving product reliability during transportation and storage, and increasing work efficiency.
[0039] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
