Abstract

The invention provides PVC board extrusion equipment which comprises a rack and a controller. Extrusion cylinders and extrusion pistons are arranged at the two ends of the rack. The two extrusion pistons are connected through a connecting rod. Meanwhile, an adjusting lead screw and a rotating motor which are connected with each other are arranged on the rack, and the adjusting lead screw is connected with the connecting rod through a sliding sleeve in screw thread connection. Stroke switches connected with the controller are further arranged on the rack, stirring rods cooperating with the stroke switches are arranged on the sliding sleeve, the piston cylinders are further connected with feeding hoppers, and solenoid valves are arranged on feeding pipes. According to the PVC board extrusionequipment, forward and reverse adjusting of a motor is achieved through the stroke switches, then the two extrusion pistons are driven through the adjusting lead screw to achieve reciprocating motion, when one extrusion piston extrudes materials, the other extrusion cylinder carries out feeding operation, constant extrusion and discharging are guaranteed during alternate operation, the work efficiency of an extrusion device is improved, the mold heat radiation efficiency is high, and the cooling effect is good.

Description

technical field [0001] The invention relates to the technical field of PVC plate processing equipment, in particular to a PVC plate extrusion equipment. Background technique [0002] PVC board is a board made of PVC as a raw material with a honeycomb mesh structure in cross section, and it is a vacuum blister film. It is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and several other industries with small-scale applications. According to the degree of softness and hardness, it can be divided into soft PVC and hard PVC, and according to the production process, it can be divided into PVC crust foam board and PVC free foam board; [0003] In the prior art, the raw materials for the production of PVC boards generall...
