Beneficial effects

[0010] This invention provides a welding machine suitable for geomembranes. Compared with the prior art, it has the following advantages: 1. This welding machine for geomembranes, by incorporating spraying components within the device, allows the transmission rod, lever, two sets of worm gear assemblies, and bidirectional screw to work together to adjust the spacing between the two sets of drive plates and the second spraying plate. This enables the first spraying plate and the two sets of second spraying plates to respectively limit the movement of the two sets of geomembranes passing through, improving the adaptability of the cleaning end of the device to geomembranes of corresponding thicknesses. Furthermore, the limiting mechanism guides the passing geomembrane.

[0014] 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.

[0015] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A welding machine suitable for geomembranes includes a mounting plate 1. The mounting plate 1 is connected to a processing component for geomembrane welding. The processing component includes a spraying component 2, which is set at the upper rear end of the mounting plate 1 for pre-cleaning treatment of the geomembrane welding end. The spraying component 2 includes a support frame 21 fixedly connected to the mounting plate 1. A first spraying plate 22 is fixedly connected to the right side of the support frame 21. An adjusting component 23 is connected to the left side of the support frame 21. A set of drive plates 27 are respectively connected to the upper and lower sides of the adjusting component 23. A set of second spraying plates 24 are respectively fixedly connected to the upper and lower sides of the two sets of drive plates 27 near the first spraying plate 22. A bifurcation pipe 25 is connected to the left side of the first spraying plate 22 and the second spraying plate 24. An air compressor 26 with a jet end fixedly connected to the bifurcation pipe 25 is fixedly connected to the left side of the mounting plate 1. Welding component 3 is set on the upper front end of the mounting plate 1 for welding adjacent geomembranes. Welding component 3 includes a connecting seat 31 fixedly connected to the mounting plate 1. A first hot melt roller 32 is rotatably connected to the right side of the connecting seat 31. An array of limiting rods 33 is fixedly connected to the connecting seat 31. A spring 34 is fixedly connected to the upper side of the limiting rod 33. A movable block 35 that is slidably connected to the limiting rod 33 is fixedly connected to the bottom of the array of springs 34. A second hot melt roller 36 is rotatably connected to the upper end of the movable block 35 near the upper end of the first hot melt roller 32. Several mounting screw holes are vertically through the edge of the mounting plate 1. Several spray holes are provided on the rear side of the first spray plate 22 and the second spray plate 24. The first spray plate 22 and the second spray plate 24 are hollow inside and communicate with the branch pipe 25 and the spray holes, respectively. Adjusting component 23 includes a transmission rod 231 rotatably connected to support frame 21. A lever 232 is coaxially fixedly connected to the front side of transmission rod 231. Two sets of bidirectional screws 234 are vertically rotatably connected to the support frame 21 near the left side of the first spray plate 22. Worm gear assemblies 233 connected to transmission rod 231 are respectively connected to the middle parts of the two sets of bidirectional screws 234. The upper and lower sides of the bidirectional screws 234 are threadedly connected to a set of drive plates 27. A set of stops 235 are fixedly connected to the top and bottom of the bidirectional screws 234 respectively. The worm inside the worm gear assembly 233 is coaxially fixedly connected to transmission rod 231. The inner worm gear and the bidirectional screw 234 are coaxially and fixedly connected. The inner worm gear and the worm in the worm gear assembly 233 mesh with each other. The transmission rod 231, the lever block 232, the two sets of worm gear assemblies 233, and the bidirectional screw 234 cooperate with each other to adjust the distance between the two sets of drive plates 27 and the second spray plate 24. This allows the first spray plate 22 and the two sets of second spray plates 24 to limit the two sides of the geomembrane that have passed through. During the geomembrane transmission process, the air compressor 26 supplies air to the first spray plate 22 and the second spray plate 24 through the branch pipe 25 to remove impurities attached to the two sides of the geomembrane before welding. The main difference between the second implementation method and the first implementation method is that: The top of the limiting rod 33 is fixedly connected to an anti-detachment block that is fixedly connected to the spring 34. The first hot melt roller 32 and the second hot melt roller 36 are in contact with each other. The air compressor 26, the first hot melt roller 32, and the second hot melt roller 36 are all electrically connected to an external controller. The first hot melt roller 32 and the second hot melt roller 36 are parallel to the first spray plate 22 and the second spray plate 24. The connecting seat 31, the limiting rod 33, the spring 34, and the movable block 35 cooperate with each other so that the first hot melt roller 32 and the second hot melt roller 36 press and heat-melt weld the two sets of geomembranes that have passed through.

[0016] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0017] In use, the user places the two sets of geomembranes to be welded together, ensuring they pass between the first spray plate 22 and the two sets of second spray plates 24. The user then pulls the movable block 35 and the second hot-melt roller 36. The movable block 35, in conjunction with the limiting rod 33, compresses the set of springs 34, allowing the two sets of geomembranes to pass between the first hot-melt roller 32 and the second hot-melt roller 36. Releasing the movable block 35, under the action of the compressed springs 34, causes the second hot-melt roller 36 to press the geomembrane against the first hot-melt roller 32. The user then rotates the lever 232, which, through two sets of worm gear assemblies 233, drives two sets of bidirectional screws 234 to rotate. These rotating bidirectional screws 234 drive two sets of drive plates 27 and the second spray plates 24 to move in opposite directions, causing the two sets of second spray plates 24 to... Two sets of geomembranes are respectively placed against the upper and lower sides of the first spray plate 22. The two sets of geomembranes are transported through an external transmission device. At the same time, the air compressor 26 is turned on and power is supplied to the first hot melt roller 32 and the second hot melt roller 36. The air compressor 26 draws in outside air and compresses it. The compressed air is then sprayed out through the branch pipe 25, the first spray plate 22, and the two sets of second spray plates 24 to blow the upper and lower surfaces of the two adjacent geomembranes to be welded, promoting the shedding of attached solid materials. After the two adjacent geomembranes to be welded pass through the first hot melt roller 32 and the second hot melt roller 36, the first hot melt roller 32 and the second hot melt roller 36 respectively perform hot melt welding on the two sets of geomembranes. The first hot melt roller 32 and the second hot melt roller 36 are existing technologies, so their internal structure and working principle will not be described in detail.
