Description
Technical field
The utility model relates to thermoforming machine, is specifically related to a kind of plastic sheet pressure former.
Background technology
Plastic sheet pneumatic thermoforming machine generally comprises unwinding device, enters sheet devices, chain rail device, film advance mechanism, heater, shaped device (comprise shaping, punching and cut), connect cup device and finished product collection device, unwinding device, enter sheet devices, chain rail device, shaped device (comprise shaping, punching and cut), connect cup device, finished product collection device sets gradually, film advance mechanism is arranged on chain rail device, and heater is arranged on the both sides up and down of chain rail device.Plastic sheet is sent from unwinding device, enters the chain rail device of plastic sheet pneumatic thermoforming machine from entering sheet devices, and is carried by chain rail device under film advance mechanism coordinates; Plastic sheet first softens through heating devices heat under the conveying of chain rail device, then carries out air-pressure forming (can be malleation or vacuum forming) by shaped device, obtains plastic products; Plastic products, through cutting or after punching, shifting out plastic sheet pneumatic thermoforming machine, being transferred to finished product collection device by connecing cup device, finally being collected by finished product collection device.
Entering sheet devices is first part that plastic sheet enters plastic sheet pneumatic thermoforming machine, its can plastic sheet is convenient, fast, send into plastic sheet pneumatic thermoforming machine in good condition, to enhancing productivity, reduce production cost and promote quality of item and play very crucial effect.
Existing enter sheet devices comprise frame, enter sheet deflector roll, enter sheet pressure roller, supporting plate and preheating device, enter sheet deflector roll and enter sheet pressure roller and be all rotatably arranged in frame, supporting plate is located in frame; Enter sheet pressure roller to be in above sheet deflector roll and with enter the pressing of sheet deflector roll, supporting plate is located at into sheet deflector roll rear; Preheating device comprises left preheating furnace and right preheating furnace, and left preheating furnace and right preheating furnace are all in above supporting plate, and left preheating furnace is arranged on the adjustable left preheating furnace mount pad in lateral attitude, and right preheating furnace is arranged on the adjustable right preheating furnace mount pad in lateral attitude.Plastic sheet from entering sheet deflector roll and enter between sheet pressure roller to insert, and arrives on supporting plate; Supporting plate plays transition supporting role, can hold plastic sheet; Plastic sheet transits to chain rail device front end under pallet support.When plastic sheet is on supporting plate, left preheating furnace and right preheating furnace preheat the position, the left side of plastic sheet and right side portion respectively, and the position, the left side of plastic sheet and right side portion are softened, so that chain rail device clamps plastic sheet better.For the ease of plastic sheet being guided on chain rail device, guide card deflector roll and guide card pressure roller is typically provided with in chain rail device front end, guide card pressure roller to be in above guide card deflector roll and with the pressing of guide card deflector roll, from entering the plastic sheet of sheet devices from passing between guide card deflector roll and guide card pressure roller and arriving chain rail device.
