DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0032] like Figure 3 As shown, the gluing system 4 includes a gluing tank 4-4, with a lower proximity switch 4-7 and an upper proximity switch 4-8 mounted on either side. A guide wheel 4-3 is located on the side of the gluing tank 4-4 near the embossing device 2. A pneumatic slurry pump 4-2, connected to the glue barrel 4-1, is mounted below the guide wheel 4-3. A gluing roller 4-6 is mounted within the gluing tank 4-4, with an adjustable scraper blade 4-5 mounted on either side. A pressure roller 4-9, connected via a gluing cylinder 4-10, is mounted directly above the gluing roller 4-6.

[0033] like Figure 3 As shown, the laminating device 5 includes a lower laminating roller 5-1 and an upper laminating roller 5-2. The upper roller surface of the lower laminating roller 5-1 is in the same horizontal plane as the upper roller surface of the glue coating roller 4-6.

[0037] The working process of the production device of a brushed asphalt damping plate provided in this embodiment is generally as follows:

[0038] Turn on the motors of the lower calendering roller 1-1 and the water-cooled conveyor belt 1-6 in the calendering system 1. The lower calendering roller 1-1 drives the upper calendering roller 1-3 to operate through gear transmission. Turn on the water pumps of the upper water spray pipe 1-4 and the lower water spray pipe 1-2. Start the damping plate mixed material spiral conveying motor to extrude the mixed material to the surface of the lower calendering roller 1-1. The mixed material is squeezed into a sheet by the upper calendering roller 1-3 and the lower calendering roller 1-1, scooped up by the scraper 1-5, and falls on the surface of the water-cooled conveyor belt 1-6. The sheet is pulled through the changing roller 1-8, then passes through the air knife 1-9, and finally changes direction through the changing roller 2 1-10 and is sent to the embossing device 2.

[0039] The flat roller 2-1 of the embossing device 2 is activated, and the embossing cylinder 2-3 is simultaneously activated to press the pattern roller 2-2 downward. The damping plate sheet is then conveyed to the tensioning device 3, and the tensioning roller 3-2 is lowered to press the sheet. When the tensioning roller 3-2 touches the lower limit switch 3-1, the gluing and laminating processes automatically speed up. When the tensioning roller 3-2 touches the upper limit switch 3-3, the gluing and laminating processes automatically speed down.

[0040] The pneumatic slurry pump 4-2 is activated to transport the adhesive from the melt barrel 4-1 to the adhesive coating tank 4-4. The pneumatic slurry pump 4-2 stops operating when the upper proximity switch 4-8 receives a signal. The gap between the second scraper 4-5 and the adhesive coating roller 4-6 is adjusted, and the adhesive coating roller 4-6 motor is turned on. The damping plate sheet is pulled through the guide wheel 4-3 to the upper roller surface of the adhesive coating roller 4-6. The adhesive coating cylinder 4-10 is activated to press the pressure roller 4-9 downward, and the damping plate sheet is then transported to the laminating device 5. During production, the pneumatic slurry pump 4-2 begins operating when the lower proximity switch 4-7 in the adhesive coating tank 4-4 receives a signal. The upper and lower proximity switches 4-8 and 4-7 are used to monitor the adhesive level in the adhesive coating tank 4-4. Photoelectric switches, infrared sensors, and other sensors can be used.

[0041] Set the parameters of the tension roller 5-5 and turn on the motor of the unwinding mechanism 5-4, pull the isolation film through the tension roller 5-5, then wrap the isolation film around the lower coating roller 5-1, pull the damping plate sheet to fit the isolation film, start the coating cylinder 5-3 to press the upper coating roller 5-2 downward, then pull the brushed glue damping plate sheet to the tensioning device 2 6, lower the tensioning roller 2 6-2 to press the sheet; when the tensioning roller 2 6-2 touches the lower limit switch 2 6-1, the forming process automatically speeds up, and when the tensioning roller 2 6-2 touches the upper limit switch 2 6-3, the forming process automatically slows down.

[0042] Start the motor of the active roller 7-1 in the forming system 7, pull the sheet to the surface of the steel belt 7-2, run with the steel belt 7-2, enter the forming machine 7-3, cut and shape to obtain the required brushed asphalt damping plate.

[0043] The utility model can realize precise control of the thickness of the coating layer and seamless fitting of the isolation membrane, and is used for continuous gluing and isolation of asphalt damping plates, effectively solving the problems of cumbersome operation, low work efficiency, missed gluing, and uneven thickness of the glue layer caused by the existing manual gluing production method. At the same time, the utility model relies on the setting of a calendering scraper to allow the damping plate sheet to smoothly enter the water-cooled conveyor belt to prevent it from sticking to the roller; it uses wind knives arranged in positive and negative directions to effectively remove moisture from the surface of the damping plate after water cooling, while further enhancing the cooling effect and avoiding the problem of the damping plate sticking to the transmission roller during the traction process; it adopts a glue-coating scraper that can be arbitrarily set and adjusted within the stroke range to meet the glue brushing needs of damping plates with different glue layer thicknesses, and at the same time, upper and lower proximity switches of the glue tank and a pressure roller driven by a cylinder are set to ensure uninterrupted supply of glue and effective and rapid transfer of the glue layer; a tension roller is arranged in front of the laminating roller for isolation film tension adjustment and constant tension unwinding, avoiding problems such as edge collapse, creases, and wrinkles during the unwinding process, and ensuring effective bonding between the isolation film and the glue layer; the arrangement of multiple sets of tensioning rollers can reduce production process inspections, meet line speed matching, and avoid excessive relaxation or tension of the damping plate during continuous traction and transportation; in addition, a high-precision four-column hydraulic forming machine is used to meet the precision cutting of damping plates of different thicknesses and shapes.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
