Embodiment 1
[0063] The hot-melt type damping sheet cooling and punching device of this embodiment, such as figure 1 As shown, it includes an air-cooling mechanism 7, a stamping and cutting device body and a special conveyor belt that passes through the stamping and cutting device body to transmit a hot-melt type damping sheet; wherein: the air-cooling mechanism 7 includes an air-cooling box 71, a blower 73 and Air-cooled conveyor belt 74; blower 73 is fixed in the described air-cooled box 71, and is buckled and placed directly above the air-cooled conveyor belt 74; The melt-type damping sheet 10 is connected, and the hot-melt type damping sheet 10 is transferred to the special conveyor belt 9; the stamping and cutting device body 8 includes two supports 82 on both sides of the special conveyor belt 9, which are laid flat and fixed on the two sides. A stamping table 83 on the side of the support platform 82 and a lifting height adjustment mechanism 84; the stamping table 83 is connected to...
Embodiment 2
[0072] The basic structure of the heat-melt damper cooling and punching device of this embodiment is the same as that of Embodiment 1. The difference and improvement are that the upper part of the air-cooled box 71 is an open opening, and a partition 72 is fixedly connected to the opening to block foreign objects. Drop into the blower 73; the wind direction of the blower 73 directly blows the hot-melt damping sheet 10 downward; the lifting height adjustment mechanism 84 is 4 lifting screws symmetrically arranged at the four corners of the stamping table 83; the special conveying The bottom of the front end of the belt 9 is provided with a damping sheet sensing mechanism 87 . The ingredients of the hot-melt damping sheet 10 include 100 kilograms of superfine light calcium powder with a particle size of 0.5 to 1 μm, 500 kilograms of superfine heavy calcium powder with a particle size of 0.5 to 1 μm, 70 kilograms of mica powder, 60 kilograms asphalt, 8 kg of asphalt modifiers suc...
Embodiment 3
[0081] The basic structure of the heat-melt type damping sheet cooling and punching device of this embodiment is the same as that of Embodiment 2, and the difference and improvement are that it also includes two sets that are respectively arranged on the front and rear sides of the stamping table 83 and directly above the special conveyor belt 9. Cutting die width adjustment mechanism 85. The ingredients of hot-melt damping sheet 10 include 175 kg of ultrafine light calcium powder with a particle size of 0.5-1 μm, 525 kg of ultra-fine heavy calcium powder with a particle size of 0.5-1 μm, 75 kg of mica fine powder, 70 kg asphalt, 9 kg of asphalt modifiers such as SBS styrene or EVA ethylene-vinyl acetate copolymer, 6 kg of softeners such as vegetable oil, rubber oil, rubber rolling oil, etc., 4 kg of fibers such as hemp fiber, aramid Fiber, wherein: the processing steps of superfine light calcium powder or superfine heavy calcium powder are:
[0082] Step 1. Mixing: fully mix...
