The invention discloses a laminating machine open type pouring device with a fixed material spraying rod. The laminating machine open type pouring device comprises a mixing head, the material spraying rod, a mixing head mounting support plate, a mixing head moving mechanism and a mixing head lifting device; the mixing head mounting support plate is mounted on an upper worktable of a laminating machine and is positioned at a feeding hole of the laminating machine; the mixing head moving mechanism is arranged on the mixing head mounting support plate; the mixing head lifting device is mounted on the mixing head moving mechanism; the mixing head is mounted on the mixing head lifting device; the mixing head moving mechanism can drive the mixing head lifting device to move; the mixing head lifting device can drive the mixing head to lift; a feeding hole of the material spraying rod is connected with a discharging hole of the mixing head; and the material spraying rod is vertical to the conveying direction of a template of the laminating machine. The laminating machine open type pouring device is simple in structure and convenient to operate. With the laminating machine open type pouring device adopted, the phenomenon of uneven pouring of a polyurethane raw material can be improved to a great extent, the foaming quality is improved, and foaming defects are reduced.
Description
technical field [0001] The invention belongs to the technical field of polyurethane pouring equipment, and in particular relates to an open pouring device for a lamination machine with a fixed sprinkling rod. Background technique [0002] With the development of my country's cold chain logistics, the market for refrigerated vehicles is developing rapidly. At present, the manufacturing process of the insulation board of refrigerated trucks basically adopts the closed molded foaming process. Due to the large size of the insulation board and the irregular reinforcing ribs inside the insulation board, the traditional closed molded foaming process adopts the fixed-point pouring method. The polyurethane foam does not flow smoothly inside the insulation board, causing the polyurethane raw material to not completely fill the entire interior of the insulation board, resulting in defects of foaming voids or uneven density. This defect will greatly affect the strength and thermal insu...
