AI Technical Summary
The existing heating plate has a fixed height and cannot meet the production requirements of large and small surface density carbon fiber products, resulting in poor versatility of the composite machine equipment and increasing customers' equipment procurement costs.
A motor-driven lifting platform is designed. The height of the heating plate can be adjusted by installing a heating plate device, and the platform can be raised and lowered using a ball screw assembly and a sprocket system to adapt to the production of prepreg products with different surface densities.
The flexible adjustment of the heating plate height is achieved, which improves the versatility of the equipment and reduces the equipment procurement cost for customers.

Description
Technical Field
[0001] The utility model relates to the field of lifting equipment, in particular to a motor-driven lifting platform for a carbon fiber prepreg heating plate. Background Art
[0002] As we all know, in the production process of carbon fiber composite materials, in order to prevent the prepreg products from cooling too quickly during the production process and to ensure that the resin has a certain viscosity, the role of the heating plate is crucial.
[0003] The manufacturing cost of composite machine equipment is high. Often, a customized composite machine equipment can produce a limited range of carbon fiber surface density of prepreg products. In order to improve the versatility of the equipment, reduce the customer's equipment procurement cost, and achieve multi-purpose use of one machine, the composite machine equipment is required to be able to produce a relatively wide range of prepreg surface density. Simply put, the equipment can simultaneously meet the production of large and small surface density carbon fiber products. The production processes for large surface density prepreg and small surface density prepreg products are not exactly the same. One of the points is that the path of the prepreg product through the heating plate is different. The existing heating plate height is fixed and cannot meet the height adjustment requirements. Summary of the Invention
