[0003] Spectacle frames generally include spectacle frames and spectacle legs. Existing spectacle frames generally use surface treatment processes such as spraying and oiling to print aesthetic patterns and patterns on the surface of spectacle frames. This relatively primitive surface treatment process Low definition and not wear-resistant; multiple electroplating treatments are required, the process cycle is long, and the operation is complicated

Embodiment 1
[0020] A production process of a composite sheet spectacle frame, comprising the following steps:
[0021] Step 1. The raw materials used for the production of boards are in a certain proportion, 40% of acetate fiber board, 10% of leather, elastic fiber, metal, wood or cloth, 30% of memory plastic, 5% of composite heat stabilizer, and 1% of composite lubricant , after preheating and drying, then mix evenly in a high-speed mixer, the speed of the high-speed mixer is 3000r / min, and the mixing time is 10-15min;
[0022] Step 2. Heat and melt the raw material mixed evenly into a viscous fluid state through a heating device, and then put it into a mold to continue heating. The heating temperature in the mold is 220-260°C, and the heating time is 20-30min; the above mold Molds for integral molding of spectacle frames and temples
[0023] Step 3, the plate blank obtained in step 2 is pre-cooled through the cooling production line;
[0024] Step 4. The pre-cooled plate blank immedia...
Embodiment 2
[0029] The difference from Example 1 is: in step one, 50% of acetate fiber board, 20% of leather, elastic fiber, metal, wood or cloth, 40% of memory plastic, 8% of composite heat stabilizer, and 2% of composite lubricant.
Embodiment 3
[0031] The difference from Examples 1 and 2 is: in step 1, 45% of acetate fiber board, 15% of leather, elastic fiber, metal, wood or cloth, 35% of memory plastic, 6% of composite heat stabilizer, and 2% of composite lubricant.

Abstract
The invention discloses a production process for a spectacle frame made from a composite plate. The production process comprises the following steps: carrying out preheating drying on raw materials for producing the plate according to a certain proportion at first, and then uniformly mixing the raw materials in a high-speed mixing machine; then carrying out heating melting on the raw materials through a heating device to enable the raw materials to achieve a viscous state, and then placing the raw materials in a die and continuing to heat; carrying out precooling treatment on an obtained plate blank through a cooling production line; immediately feeding the plate blank subjected to the precooling treatment into a pattern forming device with the production line, and forming patters on a surface of the plate blank through pressing; and carrying out adequate cooling on the plate blank, and then carrying out traction trimming treatment on the plate blank to enable the edge of the plate blank to be smooth and burr-free. The spectacle frame produced by the production process disclosed by the invention is complete in plate mixing, not liable to break, and long in life; and moreover, production is assembly-line, free from time waste and labor waste of manual work, and fast and convenient.
Description
technical field [0001] The invention belongs to the technical field of plates, and in particular relates to a production process of a composite plate spectacle frame. Background technique [0002] The spectacle frame is an important part of the glasses, mainly to support the spectacle lens, and the spectacle frame with a beautiful appearance can also play an aesthetic role. Materials mainly include metal, plastic or resin, natural materials, etc. According to the style, it can be divided into full frame, half frame, frameless and other types. [0003] Spectacle frames generally include spectacle frames and spectacle legs. Existing spectacle frames generally use surface treatment processes such as spraying and oiling to print aesthetic patterns and patterns on the surface of spectacle frames. This relatively primitive surface treatment process The clarity is low, and it is not wear-resistant; multiple electroplating treatments are required, the process cycle is long, and th...
