Abstract

The invention belongs to the field of extrusion molding, cooling and shaping, and particularly relates to equipment without downward bending and cooling used for plastic extrusion molding. The equipment comprises a water receiving tank, a water pipe A, a ring sleeve B, a ring B, a fixing sleeve, a bolt, a water pipe C and a spray nozzle mechanism, wherein two steel water pipes A which are used for cooling the lower surface of a plastic strip and are parallel to the moving direction of the plastic strip and two steel water pipes C which are used for carrying out cold cutting on the upper surface of the plastic strip and are parallel to the moving direction of the plastic strip are symmetrically mounted in the water receiving tank. According to the equipment, a water column sprayed out of a spray pipe B in the spray nozzle mechanism at high pressure and high speed mainly forms horizontal support for the plastic strip, a low-speed abutting water column sprayed out of an annular channel between the spray pipe B and the inner wall of a spray pipe A in the spray nozzle mechanism mainly cools the plastic strip and blocks splashing of the water column sprayed out of the spray pipe B at the same time, and therefore water drops are prevented from being sputtered outwards while the spray nozzle mechanism sprays and cools the plastic strip, the dryness of the surrounding environment is guaranteed, and effective recycling of cooling water is facilitated.

Description

technical field [0001] The invention belongs to the field of extrusion cooling and shaping, in particular to a device for extrusion molding of plastics without bending down for cooling. Background technique [0002] The extruder is an important plastic machine, and the production and manufacture of most plastic products can be realized by extrusion molding. [0003] The plastic material enters the extruder from the hopper, and is conveyed forward by the rotation of the screw. During the forward movement of the material, it is heated by the barrel, sheared and compressed by the screw to make the material melt. , thus realizing the change among the three states of glass state, high elastic state and viscous fluid state. In the case of pressurization, the material in a viscous flow state passes through a die with a certain shape, and then becomes a continuous body with a cross section similar to the shape of the die according to the die. Then it is cooled and shaped to form a...
