Problems solved by technology

This kind of dryer is very simple, the contact area between the blown air and the molded product is very small, and the moisture that can be taken away is limited
In order to achieve the drying effect, a production line needs to be equipped with 2-3 dryers, which increases the production cost and causes a lot of waste of energy
In addition, since the blower can only blow out the wind at normal temperature, the drying effect on the molded products is poor in the cold winter, which meets the requirements for drying the molded products.

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0027] Such as figure 1 As shown, a dryer for plastic extruded products includes a blower 1, the air outlet end of the blower 1 is provided with a heater 2, and the outer end of the heater 2 is electrically connected to a controller 3; the heater 2 The air outlet end of the air outlet is connected with a conduit 4, and the top of the conduit 4 is inserted into a horizontally arranged cylindrical wind-fixing box 5 to connect, and the bottom end of the wind-fixing box 5 is fixedly provided with a support column 6.

[0028] Such as figure 2 The shown solid air box is formed by fastening an upper curved plate 5-1 and a lower curved plate 5-5, one side of which is connected by a hinge 8, and the other side is movably connected by a hasp 5-4; the upper curved plate 5-1. Both ends of the lower arc plate 5-5 are respectively provided with baffle plates 5-...

Abstract

The invention discloses a drying machine for extruding and molding products from plastics. The drying machine comprises a blower. A heater is arranged at an air outlet end of the blower, a guide tube is connected with an air outlet end of the heater, and the top of the guide tube is connected with a tubular fixed air box which is arranged horizontally. The drying machine has the advantages that air blown out of the blower is heated by the heater, then axially flows along the fixed air box and can be in contact with each molded product over a wide area for a long contact time, heat can be sufficiently utilized, accordingly, moisture on the surface of each product can be quickly removed, a drying effect can be improved, energy consumption can be reduced, and the drying machine is high in adaptability.

Description

[0001] technical field [0002] The invention relates to a dryer, in particular to a dryer for plastic extruded products. [0003] technical background [0004] Extrusion molding is a simple and widely used molding method for plastic products. The extruder melts and extrudes the plastic, and then the shaped product is shaped by traction and cooling. The commonly used cooling method is to cool the molded product through a cold water tank. This cooling method has the advantages of low cost and high efficiency. However, since the plastic molded products are cooled by water, they contain a large amount of water, which will affect the later product processing, so the products must be dried after cooling, especially for the processing and production of plastic modified products. After being pulled out from the middle and cooled in the cooling water tank, it must be dried before pelletizing. [0005] At present, a simple dryer is commonly used for drying plastic molded products ...
