Embodiment Construction
[0047] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the invention.
[0048] figure 1 The implementation process of the production process of the PA raw material sheet provided by the embodiment of the present invention is shown.
[0049] The method includes the following steps:
[0050] Step S101, pour 100KG of raw materials into the mixing machine, use a pan to weigh 2-3KG color masterbatch and evenly sprinkle it on the surface of the raw materials, start the mixing machine, and the mixing time is 10-15 minutes;
[0051] Step S102, using a single-screw extruder, the extrusion barrel is heated in four zones, and an electromagnetic induction device is used to heat t...

The invention belongs to the technical field of production of polyamide (PA) boards and provides a process and a device for producing boards with PA as the raw material. Color masterbatch is evenly scattered on the surface of the raw material and is evenly stirred; a single screw extruder is adopted; an extrusion stuff canister is divided into four areas to be heated; an exhaust stuff canister is adopted; the plastic raw material is heated by the exhaust stuff canister and a feeding screw; water contained in the plastic raw material is evaporated; the plastic raw material is put into a die and is subjected to the processes of molding, shaping and traction / brake; the PA boards with the needed length is cut out and is put on a specified rickstand; and the stacked PA boards are subjected to heat treatment and each edge of the PA boards is subjected to beveling treatment. The method for producing the PA boards has the advantages of saved resources, reduced processes, shortened processing time, saved production cost and strong popularization and application value.
Description
technical field [0001] The invention belongs to the technical field of PA extrusion, and in particular relates to a production process and device of a PA raw material sheet. Background technique [0002] At present, the process steps of producing PA sheet products are as follows: 1. Batching / mixing process: clean the surrounding environment at the mixing head and blow the mixing machine with an air gun to prevent dirt and impurities from entering the mixing machine and raw materials. Pour 100KG of raw materials into the mixing machine, use a pan to weigh 2-3KG color masterbatch and evenly sprinkle it on the surface of the raw material, start the mixing machine, and the mixing time is 10-15 minutes, so that the raw materials and the color masterbatch are evenly mixed; 2. Feeding process : Feed the material in time to ensure that the hopper is not empty, so as to prevent the air from directly entering the drying circulation fan, which affects the drying return air speed.
