Description

Technical Field

[0001] This utility model relates to an asphalt waterproof membrane forming device, belonging to the technical field of asphalt waterproof membrane forming technology. Background Technology

[0002] Waterproof membranes are primarily used in building walls, roofs, tunnels, highways, landfills, and other applications to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up to prevent leakage, forming a leak-proof connection between the foundation and the building structure. They act as the first line of defense in waterproofing the entire project and play a crucial role. Existing waterproof membranes use a layered structure to increase strength. During production, composite pressure rollers are used as the asphalt coating forming device.

[0003] The existing bitumen waterproof membrane forming device has the following inconveniences during use: First, after extrusion forming, the excess coating of the membrane extends outward under the extrusion action, making the two sides of the waterproof material uneven; Second, the waterproof membrane will move laterally during the transfer process, causing deviation in the transfer direction, and the thickness after extrusion forming is not accurate and is not easy to adjust.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing an asphalt waterproof membrane forming device. It can make the thickness of the waterproof membrane more precise through two extrusion molding processes, and the thickness is adjustable. It can also cut off the excess coating after extrusion, so that the waterproof membrane is neat and beautiful on both sides and has a consistent width.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A bitum waterproof membrane forming device includes a sealed box, a support column is vertically fixed inside the sealed box, and a first coarse pressure roller and a first fine pressure roller are rotatably installed on the support column from top to bottom.

[0008] A second coarse roller is rotatably mounted on one side of the first coarse roller, and a second fine roller is rotatably mounted on one side of the first fine roller. The second coarse roller and the second fine roller are located on the same side of the support column. The second coarse roller and the second fine roller are driven by a drive assembly.

[0009] Cutting blades are installed at both ends of the second precision roller. The cutting blades extend beyond the surface of the second precision roller, and the outer end face of the first precision roller abuts against the inner wall of the cutting blades.

[0010] Furthermore, a horizontal arm is fixedly installed on the support column, the second coarse pressure roller is installed on the horizontal arm, and a triangular support frame is also installed on the support column. Both the first fine pressure roller and the second fine pressure roller are installed on the triangular support frame.

[0011] Furthermore, the outer diameters of the first coarse pressure roller and the first fine pressure roller are equal, and the first coarse pressure roller and the second coarse pressure roller are set horizontally, as are the first fine pressure roller and the second fine pressure roller.

[0012] Furthermore, bearing seats are installed on both the cross arm and the triangular support frame, and the two ends of the second coarse pressure roller and the second fine pressure roller are respectively rotatably mounted on the bearing seats;

[0013] An adjusting screw is horizontally mounted on the bearing housing, the cross arm is threadedly engaged with the adjusting screw via a nut, and the triangular support frame is threadedly engaged with the adjusting screw via a nut.

[0014] Furthermore, the drive assembly includes an active synchronous pulley and a passive synchronous pulley, which are driven by a synchronous belt, and the active synchronous pulley is driven by a motor;

[0015] The support column has vertical slots, and locking bolts are installed in the vertical slots to lock the triangular support frame.

[0016] Furthermore, a support plate is installed at the upper end of the triangular support frame, and the support plate is located on the side of the waterproof membrane facing away from the second precision roller.

[0018] Furthermore, a guide roller is rotatably installed on the top of the support column, and the waterproof membrane enters the guide roller after being oriented by the positioning roller.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] The upper part of the support column is equipped with a first coarse pressure roller and a second coarse pressure roller, which are horizontally set to coarsely press the waterproof membrane. Then it is conveyed to the lower horizontally set first fine pressure roller and second fine pressure roller to finely press and shape the waterproof membrane.

Detailed Implementation

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, this utility model provides an asphalt waterproof membrane forming device, including a sealed box 1, a support column 18 vertically fixed inside the sealed box 1, and a first coarse pressure roller 7 and a first fine pressure roller 9 rotatably installed on the support column 18 from top to bottom.

[0030] A second coarse roller 8 is rotatably mounted on one side of the first coarse roller 7, and a second fine roller 10 is rotatably mounted on one side of the first fine roller 9. The second coarse roller 8 and the second fine roller 10 are located on the same side of the support column 18. The second coarse roller 8 and the second fine roller 10 are driven by a drive unit. When the second coarse roller 8 and the second fine roller 10 rotate, they squeeze the waterproof membrane, thereby driving the first coarse roller 7 and the first fine roller 9 to rotate together.

[0031] like Figure 2 The second precision roller 10 has cutting blades 101 installed at both ends. The cutting blades 101 extend beyond the surface of the second precision roller 10, and the outer end face of the first precision roller 9 abuts against the inner wall of the cutting blades 101.

[0032] A horizontal arm 19 is fixedly installed on the support column 18, and the second coarse pressure roller 8 is installed on the horizontal arm 19. A triangular support frame 15 is also installed on the support column 18, and the first fine pressure roller 9 and the second fine pressure roller 10 are both installed on the triangular support frame 15.

[0033] The outer diameters of the first coarse roller 7 and the first fine roller 9 are equal. The first coarse roller 7 and the second coarse roller 8 are set horizontally, and the first fine roller 9 and the second fine roller 10 are set horizontally.

[0034] A support plate 17 is installed at the upper end of the triangular support frame 15. The support plate 17 is located on the side of the waterproof membrane facing away from the second precision roller 10. The support plate 17 supports one side of the waterproof membrane, and the cutting blade 101 cuts from the other side.

[0035] Bearing seats 11 are installed on both the cross arm 19 and the triangular support frame 15. The two ends of the second coarse pressure roller 8 and the second fine pressure roller 10 are respectively rotatably installed on the bearing seats 11.

[0036] An adjusting screw 12 is horizontally rotatably mounted on the bearing housing 11. A cross arm 19 is threadedly engaged with the adjusting screw 12 via a nut. A triangular support frame 15 is also threadedly engaged with the adjusting screw 12 via a nut. Rotating the adjusting screw 12 allows for lateral adjustment of the second coarse roller 8 and the second fine roller 10, thereby adjusting the gap between the first coarse roller 7 and the second coarse roller 8, as well as the gap between the first fine roller 9 and the second fine roller 10, thus allowing for adjustment of the thickness of the formed waterproof membrane.

[0037] The drive assembly includes an active synchronous pulley 13 and a passive synchronous pulley 14, which are driven by a synchronous belt. The active synchronous pulley 13 is driven by a motor (not shown in the figure).

[0038] The support column 18 has a vertical slot, and the locking bolt 16 is installed in the vertical slot to lock the triangular support frame 15. Adjusting the position of the locking bolt 16 in the vertical slot can adjust the position of the triangular support frame 15 on the support column 18, thereby ensuring that the synchronous belt is in a taut state.

[0039] The sealed housing 1 has a feed inlet 2 at its upper end and a discharge outlet 3 at its lower end. A positioning roller 4 is installed near the feed inlet 2, and a positioning retaining ring 5 is installed at each end of the positioning roller 4. Figure 3 Positioning retaining ring 5 is used to correct the direction of the waterproof membrane and prevent it from deviating.

[0040] A guide roller 6 is also rotatably installed on the top of the support column 18. The waterproof membrane enters the guide roller 6 after being oriented by the positioning roller 4, and is then conveyed downward from the guide roller 6.

[0041] The specific working principle of this utility model:

[0042] This invention includes a sealed box 1, within which odors are extruded to prevent their spread and environmental pollution. The waterproof membrane, after being oriented by the positioning roller 4, enters the guide roller 6 and is conveyed downwards from the guide roller 6. A first coarse pressure roller 7 and a second coarse pressure roller 8 are horizontally installed near the upper position of the support column 18. These two rollers coarsely press the waterproof membrane, which is then conveyed to the lower horizontal position between a first fine pressure roller 9 and a second fine pressure roller 10 for fine pressing. This double extrusion molding process ensures a more precise thickness for the waterproof membrane.

[0043] During the precision pressing process, the second precision pressing roller 10 is equipped with cutting blades 101 at both ends to cut off the excess coating that is extruded, so that the waterproof membrane after molding is neat and beautiful on both sides and has a consistent width.
