Description

Technical Field

[0001] The present invention relates to the technical field of transmission mechanisms for multi-layer laminators, and more particularly to an anti-falling transmission mechanism for a multi-layer laminator. Background Art

[0002] Currently, if Figure 1 As shown, the transmission mechanism of each layer of the multi-layer laminator is mainly composed of a support frame, an active transmission structure 01, a driven transmission structure 02, a chain transmission assembly 03 and a high-temperature cloth assembly 04. The high-temperature cloth assembly 04 is wound on the active transmission structure 01 and the driven transmission structure 02, wherein the driven roller 021 of the driven transmission structure 02 is directly connected and fixed with the driven sprocket 031 of the chain transmission assembly 03, that is, they are always coaxially distributed, and the high-temperature cloth assembly 04 is composed of a high-temperature cloth 041 and a pull rod 042 connected end to end, and the pull rod 042 is connected to the chain of the chain transmission assembly 03. In this way, there are two running paths for the high-temperature cloth assembly 04, one is that the pull rod 042 passes through the roller (active roller or driven roller) During the period when the pull rod 042 passes the roller (active roller or driven roller 021), it is the pitch circle traveled by the pull rod 042 (the running path of the pull rod 042 is the circumference of the pitch circle at the radius position of the pull rod 042 + the sprocket spacing) + the distance between the active roller and the driven roller 021. The other is after the pull rod 042 passes the roller (active roller or driven roller 021), it is the circumference of the roller (active roller or driven roller 021) + the distance between the active roller and the driven roller 021. Since the circumference length of the pull rod 042 passing the roller is greater than the circumference of the pitch circle of the driven roller 021, the high-temperature cloth 041 can only be tightened when the pull rod 042 passes the outermost side of the roller. At other times, the length of the high-temperature cloth 041 will be greater than the required length, resulting in the defect of the high-temperature cloth 041 falling.

[0003] In order to make up for the above-mentioned length difference, two methods are usually adopted in the existing technology. The first is to control the tension of the high-temperature cloth by tensioning the chain, that is, adjusting the pull rod to the two ends of the roller (the point of maximum tension), and adjusting the position of the driven sprocket to make the high-temperature cloth reach a tensioned state. However, on the one hand, a larger chain drive tensioning force is required to meet the requirements, and the service life is relatively low. On the other hand, the driven roller shaft and the driven sprocket are coaxial and cannot exceed the chain length adjustment, and may not be able to adjust to the required tension; the second is that the high-temperature cloth assembly also includes a spring, and the pull rod is connected to the high-temperature cloth through the spring, thereby keeping the high-temperature cloth in a tensioned state, but the spring runs in the cavity together with the pull rod, and at the same time the spring is subjected to directional force wear, has a low service life, and needs to be replaced frequently.

[0004] Therefore, providing a multi-layer laminating machine anti-falling transmission mechanism is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention
