Description

Technical Field

[0001] The utility model belongs to the field of cutting equipment, and particularly relates to an auxiliary positioning and cutting device for rubber and plastic insulation of air ducts. Background Art

[0002] Rubber-plastic insulation of air ducts is very common in ventilation and insulation systems. Traditional rubber-plastic insulation of air ducts uses four pieces of rubber-plastic sheets cut and glued separately. This process is outdated and has many joints, large cutting errors, irregular joints, easy cracking, poor visual quality, large material loss, and high energy consumption.

[0003] Now, based on the traditional rubber-plastic insulation of air ducts, there is another improved cutting method of traditional rubber-plastic insulation, which is called the whole board "one piece method". The whole board "one piece method" is used for cutting and single seam bonding for air duct insulation construction. It has the advantages of advanced technology, few interface seams, single interface seam set at the top of the air duct, firm and hidden bonding, not easy to crack, and good molding appearance quality. This construction method has been increasingly used on construction sites.

[0004] When the whole board is constructed by the "one piece method", it is necessary to make a layout and cut according to the side length of the air duct and the thickness of the rubber-plastic board. Figure 1 The combination method shown in the figure shows that the cross section of the duct insulation after construction is completed is as follows Figure 1 As shown. Calculate the layout size according to the pre-measured duct specifications. Measure the calculated layout size on the board with a steel ruler or steel tape measure, and draw the V-groove tangent line on the board with a ruler and a paintbrush. Use a paper cutter to cut the insulation board in two directions at a 45-degree angle to form a 90° "V"-shaped notch. The bottom of the "V"-shaped notch should retain a 3-5mm thick insulation board and should not be cut off.

[0005] When the whole plate is cut in one piece, 2 to 3 construction workers are needed to carry out the work. 1 to 2 people are needed to fix the ruler at the plate cutting point, and 1 person is needed to hold the paper cutter to cut, which consumes a lot of labor. For the same specification of air duct, after cutting a whole plate, it is necessary to re-draw the line on the plate to mark the position when cutting again, which is a waste of labor.
