Description

Technical Field

[0001] The utility model relates to the field of fabric folding machine technology, in particular to a speaker cloth folding and laminating device. Background Art

[0002] At present, speakers and other playback devices can be seen everywhere in life. Usually, a layer of mesh cloth is set on the outer shell of the speaker of the speaker to prevent dust and remove noise. In the production process of traditional speaker shells, it is necessary to manually fit the mesh cloth to the side of the speaker shell. In the bonding process, glue is manually applied to the joints of the speaker shell and the mesh cloth, and then the mesh cloth is folded to make the mesh cloth fit to the inner wall of the shell. However, the manual operation method has low working efficiency. At the same time, the bonding effect between the outer periphery of the speaker shell and the mesh cloth is poor, which makes the mesh cloth easy to loosen on the edge of the shell, resulting in the need to rework the product for secondary bonding.

[0003] Later, a laminating machine appeared on the market, which added side push blocks to the outer periphery of the jig, used a driving device to control the side push blocks to move toward the jig, so that the side push blocks pushed the speaker cloth to bend inward, and cooperated with the upper pressing die to be pressed on the jig to laminate the bent speaker cloth on the workpiece, thereby achieving lamination between the speaker cloth and the workpiece; however, the existing laminating machine has poor structural design, and the upper pressing die maintains a distance from the push block when it is pressed on the jig, resulting in poor lamination between the speaker cloth bent at the push block and the workpiece, causing the speaker cloth bent at the push block to warp up, so that the lamination at the edge of the speaker cloth and the workpiece is unstable, reducing the lamination quality between the speaker cloth and the workpiece, failing to meet the user's usage requirements, and having a small scope of application.
