Cooling device for plastic production molding

Abstract

The invention discloses a cooling device for plastic production and molding, and belongs to the technical field of plastic production equipment.The cooling device for plastic production and molding comprises a water tank with an opening in the top end, a frame is movably arranged in the water tank in a matched mode, and a motor is installed on the bottom wall of the water tank; a reciprocating lead screw is vertically and fixedly installed at the output end of the motor and is in threaded connection with the frame. A first elastic rod is vertically and fixedly installed on the inner bottom wall of the frame, a filter screen is movably arranged in the frame in a matched mode, a through hole matched with the first elastic rod is formed in the filter screen, and under the action of the filter screen, a first floating box, an elastic film and a first elastic strip, after cooling is completed, a workpiece falls to the top end of the first elastic strip, and then the workpiece is cooled. And then the first elastic strip drives the workpiece to shake, a water film on the surface of the workpiece can be thrown away in the shaking process, the water content of the surface of the workpiece is reduced, and the effect of reducing follow-up drying power consumption is achieved.

Description

technical field [0001] The present invention relates to the technical field of plastic production equipment, and more particularly, to a cooling device for plastic production and molding. Background technique [0002] Plastic is a polymer compound that is polymerized from monomers as raw materials through addition or polycondensation reactions. It is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and pigments. Generally speaking, thermoplastic Workpieces made of plastic or some thermosetting plastics are usually extruded. [0003] The extrusion method of the plastic extruder generally refers to melting the plastic at a high temperature of about 200 degrees, and the molten plastic forms the required shape when it passes through the mold. [0004] After searching, Chinese Patent No. CN110901020A discloses a cooling device for the production and processing of plastic profiles. The cooling device for the production and process...

Problems solved by technology

[0005] Although the above-mentioned patents can avoid cracking caused by excessive cooling of the workpiece, when the workpiece that has been cooled is taken out of the water, a layer of water film will adhere to the surface of the workpiece under the action of adhesion, so when the workpiece is subsequently dried, The dryer needs to work for a long time to remove the water film on the surface of the workpiece, resulting in an increase in cost; and every time the cooling of a workpiece is completed, the amount of water in the pool will decrease, so it is necessary to replenish cold water after working for a period of time. caused a waste of water resources
