Description

Technical Field

[0001] This application relates to the field of edge banding technology for sheet metal, and more specifically, to a pressing mechanism. Background Technology

[0002] In current furniture manufacturing, various types of boards, such as eco-boards and particleboard, are widely used. These composite boards are easy to cut and have good performance. After the boards are cut to the required dimensions, the edges need to be sealed to make them more aesthetically pleasing, sturdy, and waterproof.

[0003] During edge banding, a pressing mechanism is needed to press the edge banding tape onto the sides of the board to improve the adhesion between the board and the edge banding tape. However, existing boards come in various shapes and thicknesses, while the pressing mechanism uses a single type of roller, which can only process specific types of boards. This means that when encountering other types of boards, either the pressing mechanism or the roller must be replaced, which is slow, inefficient, and difficult to meet production needs.

[0040] The pressing mechanism provided in this application is intended to solve at least one technical problem existing in the prior art.

[0041] This application provides a pressing mechanism, such as... Figures 1-7 As shown, the pressing mechanism includes a lifting module and a pressing module with at least one set of forming pressing components 14. The forming pressing components 14 include multiple pressure rollers, which are arranged vertically and have different outer contours. The pressure rollers are set on the pressing side of the pressing module to press the edge banding tape onto the board. The driving end of the lifting module is connected to the pressing module and is used to drive the pressing components to lift.

[0042] Optionally, the molding and pressing assemblies 14 can be arranged side by side and the pressure rollers of each molding and pressing assembly 14 are located on the same side of the pressing mechanism.

[0043] In one embodiment, the number of molding and pressing components 14 can be five, with each molding and pressing component 14 having a pressure roller arranged vertically in a straight line. During the pressing process, the lifting module is controlled to move the molding and pressing component 14 up and down according to the shape of the edge banding on the side of the board, so that the pressure roller corresponding to the edge banding rises to the height of the edge banding and fits against the edge banding, thereby completing the pressing operation.

[0044] Optionally, the molding and pressing assembly 14 further includes a molding pulley seat 141 and a mounting block 145. The pressure rollers include a first pressure roller 143, a second pressure roller 146, and a third pressure roller 147.

By changing the height of the pressure rollers, the currently working pressure roller can be selected, thereby completing the pressing of sheet metal with different cross-sections. For example, when the second pressure roller 146 is adjusted to a certain height, the second pressure roller 146 is in the working state, while the first pressure roller 143 and the third pressure roller 147 are in the standby state. The first pressure roller 143 and the third pressure roller 147 can also be adjusted to the working state by adjusting their height.

[0079] The terms "first," "second," "third," "fourth," "1," "2," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than that shown in the illustrations or text descriptions.

[0080] It should be understood that although arrows indicate various operation steps in the flowcharts of this application's embodiments, the order in which these steps are implemented is not limited to the order indicated by the arrows. Unless explicitly stated herein, in some implementation scenarios of this application's embodiments, the implementation steps in each flowchart can be executed in other orders as required. Furthermore, some or all steps in each flowchart, based on the actual implementation scenario, may include multiple sub-steps or multiple stages. Some or all of these sub-steps or stages can be executed at the same time, and each sub-step or stage can also be executed at different times. In scenarios where execution times differ, the execution order of these sub-steps or stages can be flexibly configured according to requirements, and this application's embodiments do not limit this.

[0081] The above description is only an optional implementation method for some implementation scenarios of this application. It should be noted that for those skilled in the art, other similar implementation methods based on the technical concept of this application without departing from the technical concept of this application also fall within the protection scope of the embodiments of this application.
