A plastic sheet forming machine

Abstract

The invention discloses a plastic sheet forming machine. The plastic sheet forming machine comprises a box body, a main shaft, a mold support, at least two forming molds, a forming mold sealing device and a finished product sheet withdrawing device, wherein the main shaft is installed on the box body in a rotating manner, the forming molds are fixed on the mold support, a front opening of each forming mold is used for being matched with an extruder mold head, the mold support is fixed on the main shaft, the forming molds are uniformly and circumferentially distributed relative to the axis of the main shaft, cooling liquid is stored in the box body, the mold support is partially soaked in the cooling liquid, a main shaft rotation drive device is installed on the box body and connected with the main shaft in a transmission manner, a main shaft sliding drive device is installed on the box body and connected with the main shaft in the transmission manner, the forming mold sealing device is installed on the box body, the forming mold sealing device is matched with a rear opening of each forming mold on a forming workstation in a sealing manner or separated from the rear opening of the each forming mold on the forming workstation, and the finished product sheet withdrawing device is installed on the box body and cooperated with the rear opening of each forming mold on an unloading workstation to complete the finished product sheet withdrawing. The forming machine is relatively small in floor occupation area, the forming efficiency of sheets can be improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a sheet forming machine, in particular to a plastic sheet forming machine. Background technique [0002] At present, wood, cement and stainless steel facilities are used in international and domestic public facilities (such as flower beds, lawn railings, parking space floors, park guardrails, tables and chairs in public facilities, floor boards of Huzhou pavilions, etc.), requiring a lot of investment Manpower and financial resources, maintenance inconvenience. In order to promote environmental protection policies, recycled PE, PP, PET and other waste materials on the market are reused. At present, the application of plastic sheets is also being vigorously promoted. Plastic sheets can greatly reduce financial resources, reduce environmental pollution, and make waste materials reuse. However, the molding machine of present plastic sheet material is exactly to be provided with cooling cylinder at the back of extruder, and the do...

Problems solved by technology

However, this structure has some disadvantages: 1. The entire production line of the sheet forming machine is very long and occupies a large area; 2. The sheet forming machine requires many supporting structures, such as cooling devices, cutting machines, etc., and the cost investment is large; 3. The molding efficiency of this molding machine is slow, the path of the entire plastic travel is very long, the molding speed is slow, and the efficiency cannot be improved
