[0002] Waterproof membrane is a material used in building construction to prevent water penetration. It is mainly used in roofs, basements, bathrooms, tunnels, bridges and other engineering parts that require waterproofing.

[0003] A waterproof membrane hot melt welding machine is a mechanical device specifically used for hot melt welding of waterproof membranes (such as polymer waterproof materials, polyethylene polypropylene composite waterproof membranes, etc.).

[0004] In the prior art, such as the automatic feeding hot melt welding machine disclosed in Chinese Announcement No. CN207758174U, there is a machine housing, a worktable, a belt, a mounting block, a machine head one, a baffle, a cylinder, a touch control box, a support rod, a pulley, a rotating shaft, a connecting rod, a machine head two, a gear one, a motor, a main shaft, a gear two, and a support block. A baffle is fixedly connected to the middle position of the upper surface of the machine housing, and a worktable is provided on one side of the baffle. The lower surface of the worktable is fixedly connected to the upper surface of the machine housing. A cylinder is also provided on the side of the baffle near the worktable. The output end of the cylinder is connected to the machine head one, and a machine head two that matches the machine head one is fixedly connected to the upper surface of the machine housing.

[0005] The aforementioned application achieves faster overall work efficiency and reduces manual operations through the coordinated operation of multiple components. However, in actual use, the device is an open structure, which generates harmful gases when hot-melting welding workpieces. Long-term inhalation of these harmful gases will endanger the health of surrounding workers. Utility Model Content

[0006] This invention utilizes multiple filters working together to effectively filter harmful gases generated during operation, preventing harm to the health of workers and thus solving the problems mentioned in the background art.

Through the above components, harmful gases generated during operation can be effectively filtered to prevent harm to human health.

[0027] like Figure 6 As shown, handles 204 are fixedly connected to the front of HEPA filter 209, activated carbon filter 208 and chemical filter 207. The outer wall of the limiting rod 202 is slidably connected to the inner wall of the clamping plate 205. The outer wall of the clamping plate 205 is slidably connected to the front of HEPA filter 209, activated carbon filter 208 and chemical filter 207 respectively. With the handles 204, users can easily pull the corresponding filter forward so that it can slide out of the filter box 201 and complete the disassembly.

[0028] like Figure 1 As shown, the top of the vacuum pump 102 is fixedly connected to the air outlet pipe 107. The vacuum pump 102 is connected to the inside of the filter box 201. Through the air outlet pipe 107, the filtered gas can be normally discharged to the outside.

[0029] like Figure 1 As shown, a set of transparent doors 103 are hinged to the front of the housing 101. A PLC controller 104 is fixedly installed on the front of one of the transparent doors 103. Support legs 106 are fixedly connected to the bottom of the housing 101. The PLC controller 104 is electrically connected to the components to control the opening and closing of the components. The support legs 106 can improve the overall stability during use.

[0030] like Figure 2 and Figure 4As shown, a servo motor 108 is fixedly installed on the reverse side of the housing 101. A threaded rod 117 is fixedly connected to the output end of the servo motor 108. A first electric push rod 116 is fixedly installed at the bottom of the slider 119. A hot melt welding machine body 115 is fixedly installed at the shaft end of the first electric push rod 116. The outer thread of the threaded rod 117 penetrates the inner wall of the slider 119. Through the servo motor 108, the threaded rod 117 and the slider 119, the first electric push rod 116 and the hot melt welding machine body 115 can be driven to move back and forth stably, so that hot melt welding can be performed at the joint.

[0031] like Figure 2 As shown, a second connecting plate 112 is fixedly connected to the reverse side of the housing 101. A second electric push rod 111 is fixedly installed on the inner wall of the second connecting plate 112. A bracket 110 is fixedly connected to the shaft end of the second electric push rod 111. A pressure roller 109 is rotatably connected to the inner wall of the bracket 110. Through the arrangement of the second electric push rod 111, the bracket 110 and the pressure roller 109, a certain pressure can be applied to the molten edge, so that the edges of the two rolls are tightly attached together.

[0032] like Figure 3 As shown, a placement plate 113 is fixedly connected to the inner wall of the housing 101. A set of third electric push rods 105 is fixedly installed at the bottom of the fixing plate 118. A set of rubber pads 114 is fixedly connected to the shaft end of the third electric push rods 105. Through the setting of the third electric push rods 105, the placement plate 113 and the rubber pads 114, the waterproof membrane can be fixed to ensure stability during subsequent hot melt welding.

[0033] The usage and working principle of this device are as follows: First, lay a set of waterproof membrane flat on the placement plate 113. After adjusting the position, close the transparent box door 103. Start the third electric push rod 105 through the PLC controller 104. The push rod extends and retracts, causing the rubber pad 114 to move up and down. When the rubber pad 114 moves down to the appropriate position and contacts the top of the waterproof membrane, it fixes the membrane. Then, start the hot melt welding machine body 115, servo motor 108, first electric push rod 116, and exhaust fan 102. The first electric push rod 116 extends, pushing the hot melt welding machine body 115 down to the joint of the waterproof membrane. Heating melts the edge of the membrane. At the same time, the threaded rod 117, slider 119, and servo motor 108 work together to drive the first electric push rod 116 and the hot melt welding machine body 115 to move back and forth stably, completing the hot melt welding process. The harmful gases generated during the operation are drawn into the filter box 201 by the exhaust fan 102. The gas passes through H in sequence. EPA filter 209, activated carbon filter 208, and chemical filter 207 perform three filtration and adsorption processes, and are finally discharged through the exhaust pipe 107 to avoid pollution to the external environment. After welding, the second electric push rod 111 drives the bracket 110 and pressure roller 109 to move back and forth. After the pressure roller 109 contacts the waterproof membrane, it can roll under force to apply pressure to the edges of the molten membrane, so that the edges of the two membranes are tightly attached. After the operation is completed, the transparent box door 103 is opened, and the third electric push rod 105 drives the rubber pad 114 to reset, so that the waterproof membrane can be taken out. If a filter needs to be disassembled after long-term use, the user pulls the corresponding clamping plate 205 to slide it on the limit rod 202. At this time, the compression spring 203 connected to the clamping plate 205 is compressed and changes its own state. When the clamping plate 205 moves to a certain position and disengages from the filter, the user can pull the filter forward through the handle 204 to remove it from the filter box 201, thus completing the filter disassembly.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
