DETAILED DESCRIPTION

A conveyor belt 2 is provided between the two frames 1. The spreading roller 5 spreads the paint evenly on the surface of the waterproof coiled material; both sides of the spreading roller 5 are provided with a fixed seat 6 arranged on the frame 1, and the spreading roller 5 is rotatably connected to the fixed seat 6. The extrusion component 3 is arranged on the feeding side of the spreading roller 5 to extrude the paint evenly. The spreading component 4 is arranged between the extrusion component 3 and the spreading roller 5 to spread the paint horizontally. The pressing component 7 is arranged on the discharging side of the spreading roller 5 to press the air-dried paint and waterproof coiled material.

[0024] Further explanation, the extrusion assembly 3 includes a bracket 31 arranged on two frames 1; the lower end of the bracket 31 is connected to an extrusion box 34; the extrusion box 34 is connected to a conveying pipe 33; the other end of the conveying pipe 33 is connected to a material box 32 arranged on the bracket 31; a liquid pump is arranged in the material box 32; a plurality of nozzles 38 are arranged at the lower end of the extrusion box 34, and a rotating shaft 35 is also rotatably connected at the inner wall; one end of the rotating shaft 35 is connected to a driving mechanism 36, and a spiral blade 37 is wound around the side wall; the driving mechanism 36 is a motor. A plurality of nozzles 38 are arranged at equal distances at the lower end of the extrusion box 34. The spiral blade 37 can mix the adhesive transported to the extrusion box 34 evenly, and then evenly extrude the adhesive from the nozzle 38, so that the adhesive is evenly distributed on the upper end of the conveyor belt 2, avoiding uneven thickness after coating due to uneven distribution of the adhesive, thereby reducing product quality.

[0025] Further explanation, the paving assembly 4 includes a connecting frame 41 symmetrically connected to the lower end of the bracket 1 31; a reciprocating screw 42 is rotatably connected between the two connecting frames 41, and a sliding rod 44 is commonly connected, and a sliding frame 45 is also provided; one end of the reciprocating screw 42 is connected to a driving mechanism 2 43; the driving mechanism 2 43 is a motor; the sliding frame 45 is threadedly connected to the reciprocating screw 42, and is slidably connected to the sliding rod 44, and a roller 46 is also rotatably connected to the lower end of the sliding frame 45. The roller 46 is arranged vertically to the material spreading roller 5. Before the material spreading roller 5 spreads the adhesive on the waterproof coiled material, the adhesive can be spread horizontally to ensure that the thickness of the adhesive is uniform and avoid uneven laying, so that the adhesive can be better cured and tightly combined with the waterproof coiled material, thereby improving the product quality.

[0026] Embodiment 2

[0027] like Figure 5 As shown, a polymer adhesive coating device proposed by the utility model, compared with the first embodiment, this embodiment also includes: a plurality of pressing components 7 are provided on the discharging side of the material spreading roller 5. The pressing component 7 includes a bracket 2 71 arranged on two frames 1; both sides of the bracket 2 71 are provided with a slide groove 72, and the top is symmetrically connected to a spring 73; the lower ends of the two springs 73 are connected to a slider 74; the two sliders 74 are slidably connected to the corresponding slide groove 72, and a pressing roller 75 is rotatably connected between the two sliders 74. On the one hand, it ensures that the adhesive and the waterproof coiled material are closely attached to each other to prevent the adhesive from falling off the waterproof coiled material; on the other hand, it prevents the adhesive and the waterproof coiled material from warping or wrinkling, ensures the flatness of the adhesive and the waterproof coiled material, and thus improves the processing quality. At the same time, the pressing roller 75 can rotate following the transmission of the conveyor belt 2, thereby preventing the pressing roller 75 from interfering with the conveying process of the adhesive and the waterproof coiled material.

[0028] The working principle of the utility model is as follows: when working, first lay the waterproof coiled material flat on the conveyor belt 2, then start the conveyor belt 2, so that the conveyor belt 2 is transmitted in the direction of the extrusion component 3, the flattening component 4, the spreading roller 5, and the pressing component 7 in sequence. Then start the liquid pump in the material box 32, so that the adhesive flows into the extrusion box 34 along the conveying pipe 33. Then start the driving mechanism 1 36 to drive the rotating shaft 35 and the spiral blade 37 to rotate, so that the adhesive is evenly spread on the extrusion box 34 and flows out evenly along the multiple nozzles 38. Then start the driving mechanism 2 43 to drive the reciprocating screw 42 to rotate, so that the sliding frame 45 moves back and forth along the reciprocating screw 42 and the sliding rod 44, so that the roller 46 rolls back and forth, and the adhesive is evenly spread horizontally. Then make the spreading roller 5 rotate following the transmission of the conveyor belt 2, so that the adhesive is laid on the waterproof coiled material. When the adhesive and the waterproof membrane pass through the pressing assembly 7, the spring 73 drives the slider 74 to slide down the slide groove 72, so that the pressing roller 75 is pressed on the adhesive and the waterproof membrane, which can ensure that the adhesive and the waterproof membrane are closely fitted and prevent the adhesive and the waterproof membrane from warping or wrinkling.
