Description

Technical Field

[0001] The invention belongs to the technical field of PVC board production and processing, and in particular relates to a PVC board extrusion molding and conveying device. Background Art

[0002] During the production and processing of existing PVC boards, the raw material particles are melted and extruded through an extruder, then extruded and formed through a molding machine, and then transported to a cutting device for cutting and forming. During the extrusion molding of the existing molding machine, the molding plate in the molding machine has a low cooling effect on the PVC board, and the utilization rate of the coolant is low, which affects the molding of the board. Moreover, the coolant cannot be recycled after cooling, which increases the overall cost and easily causes waste of the coolant.

[0003] In order to solve the above technical problem, there is currently an existing public document, CN205297127U - a PVC board extrusion molding and conveying system for rail transit trains, which is publicly provided with an extruder, a molding machine, a conveyor and a traction machine. The molding machine includes a plurality of groups of molding plates. The spacing between the molding plates gradually decreases with the conveying direction of the PVC board. The molding plates are each provided with a cooling trough for storing coolant. A plurality of partition plates are provided in the cooling trough. The partition plates form the cooling trough into an S-shaped, winding and rugged guide cavity, and also include a circulation tank for circulating the coolant.

[0004] Although the design of cooling trough and coolant can cool down the PVC board to a certain extent during extrusion, the existing PVC board extrusion molding conveying device adopts S-shaped winding and rugged guide cavity to circulate water. During molding cooling, due to the high temperature of the PVC board, the cold water is constantly exchanging heat with the temperature of the PVC board during the process of passing through the guide cavity, which will cause the temperature of the cold water to gradually increase when passing through the guide cavity, resulting in different water temperatures in different parts of the guide cavity. Often, only the cold water temperature can be maintained near the water inlet, which greatly reduces the cooling effect of the PVC board during extrusion molding. In addition, the cooling water is only recovered by rotating spraying during circulation, which is difficult to cool quickly, and will also affect the cooling effect of the PVC board during extrusion molding. In addition, the existing device is often only suitable for a single type of PVC board extrusion molding and conveying, and the functionality is not strong. To this end, we provide a PVC board extrusion molding conveying device to solve the above problems. Summary of the invention
