Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material production, in particular to an asphalt current limiting device for producing asphalt waterproof coiled material. Background Art

[0002] SBS membrane is a thermoplastic elastomer waterproof material with the characteristics of waterproof, anti-seepage, moisture-proof and air-tight. It is suitable for the corrosion protection of various pipelines and moisture-proofing in various packages. In its production process, asphalt is needed. Asphalt has a certain fluidity and the corresponding device is needed to adjust its flow rate.

[0010] Furthermore, a rubber pad is glued and connected to one side of the sliding block.

[0011] Furthermore, a fixing threaded hole is provided at a corner of the top surface of the fixing plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting a screw and a slider, a person can turn the screw to make the slider cover the groove again, thereby cutting off the flow of asphalt. Moreover, when the slider moves, it can squeeze the asphalt remaining in the rectangular chute into the metal molding hose, thereby preventing the asphalt from solidifying in the rectangular chute for subsequent use.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 , 2 As shown in Figure 3, an asphalt flow limiting device for the production of asphalt waterproofing membranes includes a fixed plate 1, a rectangular slide groove 11 is provided on one side surface of the fixed plate 1, and a slider 7 is slidably arranged in the rectangular slide groove 11, a bearing 6 is installed on one side surface of the slider 7 through a reserved groove, a screw rod 5 is installed on the other side surface of the fixed plate 1 through a reserved threaded hole, and one end of the screw rod 5 is located in the rotating circle of the bearing 6, and a through groove 12 corresponding to the rectangular slide groove 11 is provided on the bottom surface of the fixed plate 1.

[0020] Among them, a mounting groove 10 is opened on one side surface of the top of the fixing plate 1, and an electric heating tube 9 is arranged in the mounting groove 10, a protective plate 3 is arranged on the top of the mounting groove 10, and a thermometer 4 is arranged on the top of one end of the fixing plate 1.

[0021] In this embodiment, Figure 1 , 2 As shown, when the electric heating tube 9 is working, it can heat up the inside of the rectangular chute 11 , thereby softening the asphalt, making it easier for the slider to squeeze the remaining asphalt out of the rectangular chute 11 .

[0022] A metal shaped hose 13 corresponding to the rectangular slide groove 11 is installed on one side of the fixing plate 1 by screws, and a flange 14 is welded to one end of the metal shaped hose 13 .

[0023] In this embodiment, Figure 1 As shown, personnel can set the free end of the metal shaped hose 13 to a downward state and fix it to the external pipe through the flange 14, so that when the asphalt in the rectangular chute 11 is squeezed into the metal shaped hose 13, it can flow into the external pipe.

[0024] Wherein, a rubber pad 8 is glued and connected to one side of the sliding block 7 .

[0025] In this embodiment, Figure 2 As shown, the rubber pad 8 can fully contact the inner wall of the rectangular slide groove 11, thereby improving the sealing performance of the sliding block to the rectangular slide groove 11.

[0026] Wherein, a fixing threaded hole 2 is opened at the corner of the top surface of the fixing plate 1 .

[0027] In this embodiment, Figure 1 As shown, a person can connect and fix the fixing plate 1 to an external corresponding mechanism through the fixing threaded holes 2 .

[0028] It should be noted that the utility model is an asphalt flow limiting device for the production of asphalt waterproofing membranes. When working, personnel can fix the device on the corresponding mechanism and ensure that the through groove 12 is aligned with the corresponding container. Subsequently, personnel connect the metal shaping hose 13 to the external asphalt delivery pipeline. Next, when asphalt needs to be used, personnel can rotate the screw 5 so that the slider 7 slides in the rectangular slide groove 11 and no longer covers the through groove 12, so that the asphalt can enter the rectangular slide groove 11 and then be discharged into the designated container through the through groove 12. In addition, personnel can limit the flow of asphalt by covering the area of ​​the through groove 12 by the slider 7. Next, when there is no need to inject asphalt into the container, personnel can rotate the screw 5 again so that the slider 7 covers the through groove 12 again, thereby cutting off the flow of asphalt. In addition, when the slider 7 moves, it can squeeze the asphalt remaining in the rectangular slide groove 11 into the metal shaping hose 13, thereby preventing the asphalt from solidifying in the rectangular slide groove 11 for subsequent use.
