Efficient double-line suction plastic production method and device

Abstract

The invention provides a high-efficiency dual-line plastic suction production method, comprising the steps as follows: 1) a bidirectional movable plastic suction heating furnace is arranged; the left side and the right side right below the plastic suction heating furnace are respectively provided with a set of vacuum forming processing line; 2) the plastic suction heating furnace is moved to the initial position and electrified to a given temperature, and the temperature is kept; 3) after the plastic suction heating furnace is transversely moved to one side right above the hot forming working position of the vacuum forming processing line, the plastic suction heating furnace vertically runs downwards to a given height H1 and remained for the time t1 so as to heat the material on the side of the processing line hot forming working position; 4) after the prearranged heating time t1 is reached, the plastic suction heating furnace runs upwards vertically and recovers transversely, and stops for a time t3; 5) the plastic suction heating furnace is moved to another processing line, runs downwards vertically by a height H2 and stops for a time t2; 6) the plastic suction heating furnace runs upwards vertically, transversely recovers and stops for a time t4; 7) the step 3) to step 6) are repeated. The invention also discloses a device which realizes the method of the invention.

Description

technical field [0001] The invention relates to a plastic-absorbing production technology, in particular to a high-efficiency double-line plastic-absorbing production method and equipment using one set of movable plastic-absorbing heating furnaces and two or more sets of vacuum forming processing lines. Background technique [0002] The blister production process in the prior art generally consists of processing steps such as feeding → heating → blister → cooling → stripping → material cutting, which can be completed by a single device or directly by a continuous blister production line . [0003] The earliest blister production process adopted is the "furnace type", that is, the materials to be processed (mostly plastic sheets and other film materials) are fixed on the mold device, and the blister heating furnace is close to the thermoforming station from above or from the side. After the material is heated, the blister heating furnace exits, and the mold plate at the lowe...

Problems solved by technology

[0010] The problem to be solved by the present invention is to provide a production method that improves the utilization efficiency of the heating furnace, saves energy, and improves productivity; this method can also solve the problem of excessive heating of environmentally friendly plastic materials such as APET in the prior art, causing its products to absorb The problem of poor plastic quality and transparency; the problem to be solved by the present invention is that the present invention also needs to solve the problem that one heating furnace can only be used for one production line, the product category is single, and the production efficiency is low in the existing plastic absorbing equipment
