Description

Technical Field

[0001] The utility model relates to the technical field of corner brush components of foam laminating machines, in particular to a device for quickly adjusting the spacing between corner brushes. Background Art

[0002] A large amount of laminated foam is used in the transportation packaging of home appliances to provide protection. The surface of the foam board is usually laminated to enhance its protective performance. The basic component of the laminating machine during the foam laminating process is the corner brush structure. The corner brush can continuously press the film on the foam surface with a flat brush, which is an important step in lamination. It can also press out bending lines on the surface of the foam board to meet packaging needs.

[0003] In different foam laminating processes, customized foam laminating processes of different specifications often require corner brushes to be arranged at different spacings. After completing the same batch of foam laminating, operators are generally required to manually adjust the corner brush components, or even disassemble and replace corner brush components of different specifications, which is very inconvenient, time-consuming, labor-intensive, and inefficient.

[0004] In order to solve the above problems, we have made improvements and proposed a quick adjustment device for the angle brush spacing. Utility Model Content

The inner diameter of the pin through hole 9 is equal to the width of the lock groove 7.

[0022] The outer diameter of the locking pin 10 is slightly smaller than the pin through hole 9. A first limiting ring is fixedly provided in the middle of the inner wall of the pin through hole 9. The inner diameter of the first limiting ring is equal to the outer diameter of the locking pin 10. A circular iron sheet is fixedly provided on the top surface of the locking pin 10.

Two corner brushes 15 are a group, that is, one corner brush seat 8 is a group. When the spacing between the groups needs to be adjusted, the electromagnet 4 is controlled to move on the electric guide rail 2. When it reaches above the center of the top surface of the corner brush seat 8, the electric telescopic rod 3 is lowered and the electromagnet 4 is started to adsorb the corner brush seat 8. At this time, the corner brush seat 8 is still restricted on the outer slide rail 6, but the locking pin 10 will be adsorbed upward and leave the lock slot 7. Then the electromagnet 4 is moved to drive the corner brush seat 8 and its carried distance adjustment box 11 and corner brush 15 to move until they reach the lock slot 7 at the specified position of the outer slide rail 6. After the power supply of the electromagnet 4 is released, the locking pin 10 can be lowered again and inserted into the lock slot 7. The small motor 17 is controlled to drive the threaded rod 13 to rotate through the bevel gear 18, so that the angle brush distance adjustment blocks 14 can be adjusted to move closer or farther away from each other, thereby realizing the adjustment of the spacing of the corner brushes 15 in each group.
