[0027] The insulation component includes a horizontal column 16 fixedly connected to the left side of the foaming furnace body 4. A dual-head motor 15 is fixedly connected to the middle of the inner side of the horizontal column 16. Each drive end of the dual-head motor 15 is fixedly connected to a threaded rod 14. A slider 24 is threadedly connected to the outer side of each threaded rod 14. A connecting block 26 is fixedly connected to the left side of each slider 24. An mounting block 3 is fixedly connected to the other end of each connecting block 26. A rotating shaft 13 is rotatably connected to the middle of the inner side of each mounting block 3. A fixed shaft 13 is fixed to the outer side of each rotating shaft 13. A connecting plate 12 is fixedly connected to the other end of the connecting plate 12. A fixing block 11 is fixedly connected to the side of the fixing block 11 away from the connecting plate 12. A first cavity 28 is provided on one side of the connecting plate 12. A limiting block 34 is fixedly connected to the middle of the inner side of the first cavity 28. A spring 29 is fixedly connected to the upper and lower sides of the limiting block 34. A locking rod 25 is fixedly connected to the other end of the spring 29. The other side of the locking rod 25 is slidably connected to the inner side of the through hole 22.
[0028] In this embodiment, when the user operates the equipment, they first place the material to be foamed on the conveyor belt 10 in the middle of the base 2. The conveyor belt 10 smoothly transports the material into the foaming furnace body 4 for heating and foaming. The dual-head motor 15 is started, and the dual-head motor 15 drives the threaded rods 14 on both sides to rotate synchronously, which drives the threaded slider 24 to move smoothly in the horizontal direction. The movement of the slider 24 is transmitted to the mounting block 3 through the connecting block 26, so that it moves synchronously, pulling the connecting plate 12, so that the connecting plate 12 rotates through the rotating shaft 13, and stops when the baffle 9 moves to the opening of the foaming furnace body 4.

During this process, if it is necessary to adjust the position of the baffle 9, press the locking rod 25 again so that the locking rod 25 overcomes the elastic force of the spring 29 and slides out from the currently inserted through hole 22. Then, after adjusting the baffle 9 to the required position, release the connecting plate 12. Under the elastic force of the spring 29, the locking rod 25 will be inserted into the corresponding position of the through hole 22 again to lock the position of the baffle 9.
[0029] Reference Figure 2 and Figure 5 In a preferred embodiment, the collection assembly includes a collection cover 5 disposed at the top center of the foaming furnace body 4. A suction fan body 6 is fixedly connected to the top of the collection cover 5. The top center of the suction fan body 6 is connected to the top of the housing 8 via a connecting pipe 7. A second cavity 30 is provided inside the housing 8. Slots 31 are provided on both sides of the inner wall of the second cavity 30.

[0030] In this embodiment, waste gas is generated during the foaming process. The collection hood 5 located at the top center of the foaming furnace body 4 is drawn into the waste gas by the suction fan body 6. The waste gas enters the interior of the housing 8 through the connecting pipe 7. First, it passes through the primary filter 32 in the upper slot 31 to filter out larger particulate impurities. Then, it passes through the medium-efficiency filter 33 in the lower slot 31 to further filter out smaller particulate pollutants. After being purified by two stages of filtration, the waste gas is transported to the gas storage tank 18 through the gas delivery pipe 23 at the bottom center of the housing 8 for storage, so that it can be uniformly processed or recycled later. When it is necessary to maintain the filter inside the housing 8, the operator can open the sealing door 21 by holding the handle 20 at the front of the sealing door 21 to clean or replace the primary filter 32 and the medium-efficiency filter 33.

[0037] Working principle: The user starts the dual-head motor 15, which drives the threaded rods 14 on both sides to rotate synchronously, causing the threaded slider 24 to move smoothly horizontally. The movement of the slider 24 is transmitted to the mounting block 3 through the connecting block 26, causing it to move synchronously and pull the connecting plate 12, causing the connecting plate 12 to rotate through the rotating shaft 13. When the baffle 9 moves to the opening of the foaming furnace body 4, it stops. At this time, the spring 29 will drive the locking rod 25 to reset and engage in the through hole 22, completing the fixation of the connecting plate 12 and sealing the opening of the foaming furnace body 4 to achieve the heat preservation effect and effectively reduce heat loss. During the operation of the equipment, exhaust gas is generated. Under the action of the suction fan body 6, the exhaust gas is removed. The exhaust gas is drawn in and enters the housing 8 through the connecting pipe 7. It first passes through the primary filter 32 in the upper slot 31 to filter out larger particulate impurities, and then passes through the secondary filter 33 in the lower slot 31 to further filter out smaller particulate pollutants. After being purified by two stages of filtration, the exhaust gas is transported to the gas storage tank 18 through the gas delivery pipe 23 at the bottom center of the housing 8 for storage, so that it can be uniformly treated or recycled later. When it is necessary to maintain the filters inside the housing 8, the operator can open the sealing door 21 by holding the handle 20 at the front of the sealing door 21 to clean or replace the primary filter 32 and the secondary filter 33. At the same time, different types of filters can be installed according to the actual needs of the user.
