The packaging machine is mainly used to wrap a layer of stretch film on the outside of the sandwich panel to avoid damage to the sandwich panel during transportation and storage and reduce moisture and flying dust pollution. The stretch film makes a spiral motion relative to the sandwich panel. When wrapping, replacing the stretch film requires manual operation, which takes about 30 seconds. Basic data description of the four-sided packaging machine: Minimum packaging length: 3.5 M Maximum packaging length: 12.5 M Thickness of each plate: 40-250 mm Maximum height after stacking: 1.1M Maximum width: 1250 mm Working speed: About 0-5m/min Overall dimensions: 14m*2.7m*2.6m Machine weight: 5 tons Rotating circle diameter: 1828mm Specifications of PE stretch film used: Width: 500mm, thickness: 18-30um. (Weight less than 15kg, core inner diameter 76mm) Each time The repeating size of the wrapping is 0-300mm (adjustable); the stretching rate of the wrapping film is not less than 150%; the height of the conveying roller from the ground is 700mm; automatic block system (pad); (length 900~1200mm, width 200mm, The automatic packaging machine (height 100mm) includes the following devices: winding and rotating device; film placing bracket; automatic wrapping film wrapping device; automatic wrapping film cutting device; operation control system; internal small conveyor frame; block device (EPS); electrical control system ( Electronic control part); Description of the working process of the packaging machine: The stacked sandwich panels are transported through the conveyor rack; after entering the packaging machine, the transportation stops first. The rotating ring first drives the stretch film to wrap several turns around the front end of the sandwich plate and tighten it; the conveying starts, and the stretch film starts to wrap around the sandwich plate at the same time; after the wrapping is completed, the conveying stops. The stretch film is still tightened on the sandwich panel; after the automatic film cutting device automatically cuts off the film, it waits for the next cycle; the packed sandwich panels leave the packaging machine and wait for forklift transportation and the next packaging cycle. Description of the working process of the blocking device: First, put the EPS foam strips into the material library of the blocking device; then push the EPS foam strips to the pre-blocking position through the motor and chain drive, which is lower than the stacked sandwich core The surface of the board (rubber roller surface); controlled by the encoder, when a pad is needed, the cylinder will insert the pre-rolled EPS foam strip under the sandwich panel to cushion the board. If more pads are needed block, the equipment will push the EPS under the stacked sandwich panels as required.
