Abstract
Description
Technical Field
[0001] This utility model relates to the field of edge sealing machine technology, and in particular to a hot melt waterproof membrane edge sealing machine. Background Technology
[0002] In the field of building waterproofing engineering, hot-melt waterproof membranes are widely used due to their excellent waterproofing performance and durability. Edge sealing, as a crucial step in waterproofing construction, directly affects the overall quality and service life of the waterproofing project. Therefore, hot-melt waterproof membrane edge sealing machines have become indispensable equipment in the construction process. Their performance and ease of operation have a significant impact on construction efficiency, waterproofing effect, and project cost.
[0003] Common hot-melt waterproof membrane edge sealing machines typically employ fixed edge sealing rollers and flame guns. The fixed edge sealing rollers are rigidly connected to the equipment, and during construction, the machine's movement is manually controlled to roll and press the edges of the hot-melt membrane. The flame gun is also fixed at a fixed angle, heating the membrane edges in a pre-set direction. The technical principle of this type of edge sealing machine is to use a stable heating device to heat-melt the membrane edges, and then achieve a seal through mechanical rolling, thus meeting the needs of conventional flat waterproofing construction to a certain extent.
[0004] In actual waterproofing construction, existing hot-melt waterproof membrane edge sealing machines often encounter uneven building surfaces with minor bumps and undulations. When faced with uneven membrane surfaces, it is difficult to maintain uniform pressure between the sealing roller and the membrane surface, resulting in insufficient rolling pressure in some areas. This leads to the membrane edges not being able to adhere tightly, and the hot-melt adhesive not being able to fully fill the gaps, thus affecting the waterproof sealing effect and leaving potential leakage risks. Therefore, a new hot-melt waterproof membrane edge sealing machine is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a hot-melt waterproof membrane edge sealing machine, which aims to improve the problem in the prior art that when encountering an uneven membrane surface, the pressure between the sealing roller and the membrane surface is difficult to maintain evenly, and some areas are prone to insufficient rolling pressure, resulting in the membrane edges not being able to fit tightly and leaving potential leakage risks.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A hot-melt waterproof membrane edge sealing machine includes a support frame, a pulley rotatably connected inside the support frame, a push handle provided on the side wall of the support frame, a gas pipe provided inside the support frame, a flame gun provided on the side wall of the support frame, an edge sealing roller provided on the side wall of the support frame, an elastic component provided on the side wall of the support frame, and an adjustment component provided on the side wall of the support frame.
[0008] The elastic component includes a spring, a fixing frame is fixedly connected to the upper surface of the bracket, a mounting plate is fixedly connected to the side wall of the fixing frame, a sliding rod is slidably connected inside the mounting plate, a mounting frame is fixedly connected to the lower surface of the sliding rod, the side wall of the sealing roller is rotatably connected inside the mounting frame, a fixing block is fixedly connected to the side wall of the sliding rod, one side wall of the spring is sleeved on the side wall of the sliding rod, and a limit ring is fixedly connected to the side wall of the sliding rod.
[0009] As a further description of the above technical solution:
[0010] The adjustment assembly includes a connecting frame, the side wall of which is fixedly connected to the side wall of the bracket, and the side wall of the flame gun is rotatably connected inside the connecting frame.
[0011] As a further description of the above technical solution:
[0012] One end of the spring is fixedly connected to the side wall of the fixing block, and the other end of the spring is fixedly connected to the side wall of the mounting plate.
[0013] As a further description of the above technical solution:
[0014] An adjustment disc is fixedly connected to the side wall of the flame gun, and the adjustment disc has multiple adjustment holes inside.
[0015] As a further description of the above technical solution:
[0016] A fixing strip is fixedly connected to the side wall of the bracket, and a fixing shell is fixedly connected to one end of the fixing strip.
[0017] As a further description of the above technical solution:
[0018] A rod is slidably connected inside the fixed shell, and the side wall of the rod is slidably connected inside the adjustment hole.
[0019] As a further description of the above technical solution:
[0020] A pull ring is fixedly connected to one end of the insertion rod, and a fixing ring is fixedly connected to the side wall of the insertion rod.
[0021] As a further description of the above technical solution:
[0022] A second spring is fitted on the side wall of the insertion rod. One end of the second spring is fixedly connected to the inside of the fixed shell, and the other end of the second spring is fixedly connected to the side wall of the fixed ring.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when the surface of the roll material is uneven, the slide bar will slide inside the mounting plate, and the fixing block will squeeze the spring. The spring will undergo elastic deformation, causing the sealing roller to follow the ups and downs of the roll material surface through the mounting frame, always maintaining appropriate pressure with the roll material surface. This ensures that the edge of the molten roll material is rolled flat, so that adjacent roll materials are tightly bonded to form a sealed joint. This solves the problem that when some hot-melt waterproof roll material sealing machines encounter uneven roll material surfaces, the pressure between the sealing roller and the roll material surface is difficult to maintain evenly, and some areas may have insufficient rolling pressure, resulting in the roll material edge not being tightly bonded and leaving a potential leakage risk. The above structure improves the sealing effect of the sealing roller.
[0025] 2. In this utility model, when the angle needs to be adjusted, the pull ring is pulled to drive the insert rod out of the adjustment hole of the adjustment plate. At this time, the flame gun can rotate around the connecting frame. After adjusting to the appropriate angle, the pull ring is released. Under the elastic force of the second spring, the insert rod is inserted into the corresponding adjustment hole, and the flame gun is fixed at that angle to meet the heating requirements of the edge of the waterproof membrane under different thicknesses and construction scenarios.

Detailed Implementation
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1-3 This utility model provides an embodiment of a hot-melt waterproof membrane edge sealing machine, including a support 1. A pulley 2 is rotatably connected inside the support 1, and the pulley 2 is used to move the edge sealing machine on the surface of the waterproof membrane. A push handle 3 is provided on the side wall of the support 1, which is easy for the operator to hold and provides a force point for pushing or pulling the support 1. A gas pipe 4 is provided inside the support 1, and a flame gun 5 is provided on the side wall of the support 1. The flame gun 5 heats the edge of the waterproof membrane by spraying flames, melting the hot-melt adhesive or asphalt material on the edge of the membrane, creating conditions for subsequent edge sealing operations. An edge sealing roller 6 is provided on the side wall of the support 1, which is used to roll and press the edge of the hot-melt membrane, compacting the melted edge of the membrane, making adjacent membranes tightly bonded to form a sealed joint. An elastic component and an adjustment component are provided on the side wall of the support 1.
[0035] The elastic component includes a spring 13. A fixing frame 7 is fixedly connected to the upper surface of the bracket 1. A mounting plate 8 is fixedly connected to the side wall of the fixing frame 7. A sliding rod 11 is slidably connected inside the mounting plate 8. The sliding rod 11 cooperates with the mounting plate 8 to slide up and down. A mounting frame 9 is fixedly connected to the lower surface of the sliding rod 11. The mounting frame 9 is used to install the edge sealing roller 6. A fixing block 10 is fixedly connected to the side wall of the sliding rod 11. The fixing block 10 is used to fix one end of the spring 13 and, together with the mounting plate 8, limits the movement of the spring 13. The spring 13 is designed to work stably on the slide rod 11. The side wall of the spring 13 is sleeved on the side wall of the slide rod 11. The function of the spring 13 is to undergo elastic deformation and generate elastic force when it is subjected to external compression or tension. The side wall of the slide rod 11 is fixedly connected to a limit ring 12. The limit ring 12 is used to limit the sliding range of the slide rod 11 in the mounting plate 8 and prevent the slide rod 11 from falling off the mounting plate 8. One end of the spring 13 is fixedly connected to the side wall of the fixing block 10, and the other end of the spring 13 is fixedly connected to the side wall of the mounting plate 8.
[0036] Reference Figures 4-5The adjustment assembly includes a connecting frame 14, whose side wall is fixedly connected to the side wall of the support 1. The side wall of the flame gun 5 is rotatably connected inside the connecting frame 14. The flame gun 5 rotates in coordination with the connecting frame 14, achieving the purpose of adjusting the flame spray direction according to different construction needs. An adjustment disc 16 is fixedly connected to the side wall of the flame gun 5. The adjustment disc 16 is used to provide positioning points for multiple adjustment angles. Multiple adjustment holes 17 are opened inside the adjustment disc 16. The adjustment holes 17 at different positions correspond to different rotation angles of the flame gun 5. A fixing strip 15 is fixedly connected to the side wall of the support 1. A fixing shell 18 is fixedly connected to one end of the fixing strip 15. A plug rod 19 is slidably connected inside the fixing shell 18. The plug rod 19 cooperates with the fixing shell 18 to adjust the flame spray direction. The sliding motion allows insertion or removal of the adjustment hole 17 of the adjustment disc 16, thereby controlling the fixing and adjustment of the angle of the flame gun 5. The side wall of the insertion rod 19 is slidably connected to the inside of the adjustment hole 17. One end of the insertion rod 19 is fixedly connected to a pull ring 20, which allows the operator to apply force to pull the insertion rod 19, facilitating the operation of adjusting the angle of the flame gun 5. A fixing ring 21 is fixedly connected to the side wall of the insertion rod 19, and a second spring 22 is sleeved on the side wall of the insertion rod 19. The function of the second spring 22 is to provide elasticity when the insertion rod 19 is pulled out of the adjustment hole 17, so that the insertion rod 19 can automatically return to the adjustment hole 17 when no external force is applied. One end of the second spring 22 is fixedly connected to the inside of the fixing shell 18, and the other end of the second spring 22 is fixedly connected to the side wall of the fixing ring 21.
[0037] Working Principle: When using this hot-melt waterproof membrane edge sealing machine, the operator first holds the push handle 3, utilizing the rolling friction between the pulley 2 connected inside the bracket 1 and the ground to pull the bracket 1, moving the entire edge sealing machine across the surface of the waterproof membrane. Once the machine reaches the working position, the equipment is started, and the gas pipe 4 begins to function, stably delivering gas to the flame gun 5. After ignition, the flame gun 5 sprays flames to heat the edges of the waterproof membrane, melting the hot-melt adhesive or asphalt material at the edges. During the edge sealing process, when encountering uneven membrane surfaces, the edge sealing roller 6 is subjected to the force generated by the changes in the membrane surface height, which is transmitted to the slide rod 11 through the mounting frame 9. The slide rod 11 then slides inside the mounting plate 8. At this time, the fixing block 10 moves with the slide rod 11, compressing the spring 13 sleeved on the side wall of the slide rod 11, causing the spring 13 to undergo elastic deformation. The elastic force generated by the spring 13 pushes the slide rod 11 and its connected components... The mounting frame 9 and the sealing roller 6 allow for dynamic adjustment to follow the contours of the membrane surface, maintaining appropriate and uniform pressure. This ensures the melted membrane edges are rolled flat, creating a tight seal between adjacent membrane sections and guaranteeing waterproofing. When the angle of the flame gun 5 needs to be changed, the operator pulls the pull ring 20, causing the insertion rod 19 to compress the second spring 22 and pull it out of the adjustment hole 17 on the adjustment plate 16. At this point, the flame gun 5 can rotate freely around the connecting frame 14. After adjusting it to the appropriate angle according to construction requirements, the operator releases the pull ring 20. Under the elastic force of the second spring 22, the insertion rod 19 is reinserted into the corresponding adjustment hole 17, firmly fixing the flame gun 5 at that angle. This allows the flame gun 5 to precisely heat the edges of waterproof membranes of different thicknesses and construction scenarios at the appropriate angle, ensuring that the sealing machine completes the sealing work of the hot-melt waterproof membrane efficiently and with high quality.
