Problems solved by technology

This method can only produce 3-15 mm thick boards. The thicker the thickness, the worse the effect, or even lose money. Therefore, changing the PVC foaming effect and reducing the board density is the key to the problem.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described.

[0019] A PVC foam board making machine, on a vertical frame 11, three tangential calender rolls 4, 5 and 6 are arranged from bottom to top; Extruder 1 enters an inlet of proportional valve 5 through runner 2 and quantitative pump 12; a surface-enhanced layer extruder 10 and a surface aesthetic layer extruder 13 are respectively arranged above and below the extruder 1, and two extruders Exit the machine through the respective runners 2 and respective quantitative pumps 12, and enter the other two inlets of the proportional valve 15 respectively; an outlet of the proportional valve 5 is connected to the flat mold 3; the outlet of the flat mold 3 is aimed at entering the calender roll 4 and Cut-out for calender roll 5.

[0020] The proportional valve 15 is for adjusting the different flow ratios of the three inlets. Electro-hydraulic proportional valves can be used to facil...

Abstract

The invention relates to processing equipment of a PVC (Polyvinyl Chloride) foaming plate, in particular to a making machine of the PVC foaming plate. The making machine of the PVC foaming plate is characterized in that three tangent felt wrapped rolls (4, 5, 6) are arrayed on a vertical machine frame (11) from bottom to top; an extruder (1) positioned at one side of the machine frame (11) enters one inlet of a proportional valve (15) through a flow passage (2) and a constant rate pump (12); a surface enhancement layer extruder (10) and a surface beauty layer extruder (13) are respectively arranged above and below the extruder (1) and respectively enter another two inlets of the proportional valve (15) through respective flow passages (2) and constant rate pumps (12); one outlet of the proportional valve (15) is communicated with a plain end mould (3); and the outlet of the plain end mould (3) corresponds to a notch between the felt wrapped roll (4) and the felt wrapped roll (5). The invention fills the blank of production processing equipment in the field, changes the traditional PVC foaming processing mode, cancels the extrusion of an upper layer and a lower layer and the compounding form of a finished membrane during processing, greatly reduces the product density, lowers the product cost and has very tremendous economic value.

Description

technical field [0001] The invention relates to processing equipment for PVC foam boards, in particular to the structure in which the PVC foam boards are manufactured by an injection machine. Background technique [0002] PVC foam board is also known as Chevron board and Andy board. Its chemical composition is polyvinyl chloride, which has the properties of sound insulation, sound absorption, heat insulation and heat preservation. It is flame retardant and can self-extinguish without fire, so it can be used safely. It has the performance of moisture-proof, mildew-proof, non-absorbent, and good shock-proof effect. Its color can be kept unchanged for a long time, and it is not easy to age. PVC foam board is light in texture, convenient for storage, transportation and construction. It can be constructed using general wood processing tools. It can be drilled, sawed, nailed, planed, glued, etc. like wood. It is suitable for thermoforming, heating bending and folding processi...
