Forming mechanism of PVC plate

Abstract

The invention relates to a forming mechanism of a PVC plate. The forming mechanism comprises a mixer, an extruder, a feeder, a mold, a laminating calender, a tractor and a plate shearing machine whichare sequentially connected end to end, wherein the laminating calender and the tractor are connected through a bracket; a material uniformizing device is arranged between the feeder and the mold andused for uniformly spreading materials discharged from the feeder; a drying device is arranged on the front section of the bracket and used for drying the plate output from a discharge port of the laminating calender; a trimming and slitting device is arranged on the rear section of the bracket and comprises two side guide plates which can get close to or away from each other and a trimming mechanism; the side guide plates are used for centering and guiding before trimming of the PVC plate; and the trimming mechanism is used for symmetrically cutting two side edges of the PVC plate. The forming mechanism has the benefits as follows: the material uniformizing device spreads and compacts the materials, and the materials have no holes and are uniform after entering the mold; the drying devicecan quickly dry the materials; and the symmetric side guide plates can center and guide the PVC plate, and the trimming mechanism can guarantee cutting symmetry.

Description

technical field [0001] The invention relates to a production equipment for PVC boards, in particular to a forming mechanism for PVC boards. Background technique [0002] The PVC board is a board made of PVC as a raw material with a honeycomb mesh structure in section. It is a kind of vacuum blister film, which 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. According to the production process, it can be divided into PVC crust foam board and PVC free foam board. The raw materials of PVC foam products have flame retardant and self-extinguishing properties, an...

AI Technical Summary

Problems solved by technology

[0003] In the production process of PVC boards, mixers, extruders, feeders, moulds, laminating calenders, tractors, shears and brackets are required. Before the material from the feed port enters the mold, it is not flattened and compacted, resulting in holes in the material after entering the mold, and the material is uneven; there is no drying device on the bracket, and the material is sheared before it is completely dry, which affects Quality; there is no symmetrical side guide plate on the trimming and slitting device, the PVC board cannot be centered and guided, and the trimming mechanism cannot guarantee the symmetry of cutting
