Embodiment
[0029] like Figure 1-5As shown, it is a structural schematic diagram of the overflow mechanism of the present embodiment. The overflow mechanism for bitumen waterproof coil coating includes a material delivery pipe 630 for feeding and an overflow hopper 400 for coating. The valve for controlling the flow rate, the longitudinal section of the overflow hopper 400 is an asymmetric inverted trapezoid, the overflow hopper 400 is installed above the feeding pipe 630, the lower surface 401 of the overflow hopper is provided with an asphalt inlet 402, and the upper end of the feeding pipe 630 is provided with a feeding pipe overflow port 631 , The overflow port 631 of the delivery pipe is located in the asphalt inlet 402 . In this embodiment, the asymmetric inverted trapezoidal design can adjust the upper surface opening size and the hopper depth of the overflow hopper 400 to a suitable range, the upper surface opening is larger, and the hopper is shallower at the same time, and a mi...

The invention relates to the technical field of production equipment for waterproof coiled materials, and more specifically, relates to a flashing mechanism for coating asphalt waterproof coiled materials. The overflow mechanism for bitumen waterproof coil coating includes a feeding pipe for feeding and an overflow hopper for coating, the feeding pipe is provided with a valve to control flow, and the longitudinal direction of the overflow hopper is The section is an asymmetric inverted trapezoid, the overflow hopper is installed above the material conveying pipe, the lower surface of the overflow hopper is provided with an asphalt inlet, the upper end of the conveying pipe is provided with an overflow port of the conveying pipe, and the overflow port of the conveying pipe Set in the asphalt inlet. Adopting the overflow mechanism for bitumen waterproofing membrane coating according to the present invention does not cause the situation that the base fabric has a large tension and shrinks severely in the subsequent process, and bitumen waterproofing membranes with a small shrinkage rate can be produced; at the same time, it provides a This miniaturized design of the overflow mechanism can achieve coating on the lower surface of the base fabric while saving the space occupied by the installation and use of coating equipment.
Description
technical field [0001] The invention relates to the technical field of production equipment for waterproof coiled materials, and more specifically, relates to a flashing mechanism for coating asphalt waterproof coiled materials. Background technique [0002] Asphalt waterproofing membrane refers to a roll material made of asphalt material, tire material and anti-adhesive material spread on the surface, also known as linoleum, which is often used for pasting waterproof layers. Bitumen waterproofing membranes include tire membranes and tireless membranes. Any roll-shaped material made of thick paper or glass cloth, asbestos cloth, cotton and linen fabrics and other tire materials impregnated with petroleum asphalt is called tire-shaped roll material; asbestos, rubber powder, etc. are mixed into the asphalt material, and after rolling The resulting roll material is called a rolled roll, that is, a tireless roll. [0003] Modified asphalt waterproofing membrane is commonly kno...
