Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment heat sealing machines, and in particular to a waste gas treatment system for high-frequency heat sealing machines, and in particular to a method for using the waste gas treatment system for high-frequency heat sealing machines. Background Art

[0002] Toxic gas refers to toxic and harmful gases discharged by humans in the process of production and life. In particular, chemical plants, steel mills, pharmaceutical plants, coking plants and refineries, etc., emit toxic gases with a strong odor, seriously polluting the environment and affecting human health. Toxic gas contains a large amount of harmful gases, which need to be decontaminated before being discharged. In the production process of the chemical industry, gas substances are often involved in the reaction. These gas substances include toxic gases used for reaction, waste gases, reaction gases mixed with impurities, and purified gases used to discharge into the air. Except for the purified gases that have little impact on the human body and the environment, toxic gases, waste gases, and reaction gases mixed with impurities cannot be discharged directly. They must be discharged after reaction or purification to meet the emission standards. Direct discharge will have a certain impact on the human body and the environment. Some substances contained in toxic gases can attach to red blood cells, reducing the oxygen carrying capacity of red blood cells. The more toxic gases are inhaled, the lower the oxygen carrying capacity of red blood cells. Inhaling excessive toxic gases can cause suffocation or even death.

[0003] When the high-frequency heat sealing machine is heat-sealing plastics and other materials, the high temperature will cause the plastics and other materials to release toxic substances, causing toxic gases to fill the area around the high-frequency heat sealing machine. Workers who stand in front of the high-frequency heat sealing machine for a long time are very likely to inhale large amounts of toxic gases, endangering their lives and health.

[0004] Chinese patent CN111482080B discloses an exhaust gas treatment system for a high-frequency heat sealing machine. The patent sets an air intake duct at the working end of the heat sealing machine body, and sets an exhaust device in the air intake duct. The exhaust device can only face one side of the working end of the heat sealing machine body, and does not limit the toxic substances generated during the heat sealing of plastics, which can easily lead to the diffusion of toxic substances. The exhaust device cannot completely exhaust the toxic substances. Summary of the invention

[0005] In view of the above problems, an exhaust gas treatment system for a high-frequency heat sealing machine is provided. The present invention arranges an upper cover body, a lower cover body, a gas driving device and a sealing device, so that the toxic substances generated by the upper heat sealing block and the lower heat sealing block when heat-sealing the heat-sealed material can be fully absorbed, thereby preventing the staff from inhaling the escaped toxic gas.

[0050] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] Reference Figures 1 to 12 As shown: an exhaust gas treatment system for a high-frequency heat sealing machine, including a heat sealing machine body 1, the heat sealing machine body 1 includes an upper heat sealing block 11 and a lower heat sealing block 12, a lower cover body 3 surrounding the lower heat sealing block 12 is provided on the heat sealing machine body 1 at the position of the lower heat sealing block 12, an upper cover body 2 capable of surrounding the upper heat sealing block 11 is provided on the upper heat sealing block 11, a gas driving device 4 for placing the upper heat sealing block 11 and capable of sliding in the upper cover body 2 is provided between the upper heat sealing block 11 and the upper cover body 2, a sealing device 5 is provided at one end of the upper cover body 2 and the lower cover body 3 facing the device for placing the heat sealing material, and a degassing cavity is formed when the upper cover body 2, the lower cover body 3, the gas driving device 4 and the sealing device 5 are combined.

[0052] The staff places the material to be heat-sealed between the upper heat-sealing block 11 and the lower heat-sealing block 12, and the upper heat-sealing block 11 moves downward and presses against the lower heat-sealing block 12 to clamp the material to be heat-sealed. The high temperature generated by the operation of the upper heat-sealing block 11 and the lower heat-sealing block 12 splices the heat-sealed materials, and the heat-sealed materials, especially plastic materials, are easy to release toxic substances at high temperatures. The upper cover body 2 surrounding the upper heat-sealing block 11 and the lower cover body 3 surrounding the lower heat-sealing block 12 confine the gas containing toxic substances to the interior of the degassing cavity. After the heat-sealing is completed, the upper heat-sealing block 11 is separated from the lower heat-sealing block 12, and the staff extracts the heat-sealed material, and then the gas driving device 4 works to extract the toxic gas in the degassing cavity into the filtering and purification device, so that the toxic substances generated by the upper heat-sealing block 11 and the lower heat-sealing block 12 when the heat-sealing material is heat-sealed are fully absorbed, thereby preventing the staff from inhaling the escaped toxic gas.

[0053] Reference Figure 7 As shown: an air inlet is provided on the side of the lower cover body 3 away from the material placement, an opening and closing plate 31 is provided on the upper cover of the air inlet, and a first limiting telescopic rod 32 for limiting the opening and closing angle of the opening and closing plate 31 is provided in the middle of the opening and closing plate 31.

[0054] The height of the lower cover body 3 is consistent with the height of the lower heat sealing block 12, the upper part of the opening and closing plate 31 is hinged to the inner wall of the lower cover body 3 through a lotus leaf, the height at which the opening and closing plate 31 is hinged to the lower cover body 3 is lower than the height of the lower cover body 3, one end of the first limiting telescopic rod 32 is connected to the bottom of the lower cover body 3 through a hinge seat, the other end of the first limiting telescopic rod 32 is hinged to one end of the opening and closing plate 31 through a hinge seat, the opening and closing plate 31 covers the air inlet of the lower cover body 3, the lower cover body 3, the upper cover body 2 and the gas driving device 4 form a sealed cavity, the toxic gas fills the sealed cavity, and when the gas driving device 4 is evacuated, the air in the sealed cavity is quickly evacuated, and the sealed cavity is sealed. A negative pressure is formed in the cavity. If no new air enters, it is difficult for the gas drive device 4 to discharge the newly generated toxic substances. By setting the opening and closing plate 31, after a negative pressure is formed inside the sealed cavity, the larger external air pressure pushes the opening and closing plate 31 to rotate, and a gap appears between the opening and closing plate 31 and the air inlet. New external air flows into the cavity under the push of the air pressure difference. The first limiting telescopic rod 32 limits the rotation angle of the opening and closing plate 31 to prevent the angle between the opening and closing plate 31 and the lower cover body 3 from being too large, causing toxic substances to overflow from the gap between the opening and closing plate 31 and the lower cover body 3, thereby enabling the gas drive device 4 to continuously extract the toxic gas from the cavity.

[0055] Reference Figure 6 As shown: the upper cover body 2 is provided with an opening on the side facing the material placement, and a vertical plate 21 slidably connected thereto is provided at the opening of the upper cover body 2, an elastic mechanism 22 is provided at the upper end of the vertical plate 21, and a first linear drive 23 capable of driving the upper cover body 2 to move up and down is provided at the upper end of the upper cover body 2.

[0056] Slide grooves are provided on both sides of the opening of the upper cover body 2, and sliders 211 are provided on both sides of the vertical plate 21. The sliders 211 are slidably connected to the slide grooves. The elastic mechanism 22 includes a bracket 221 and a first spring telescopic rod 222. The bottom of the bracket 221 is fixedly connected to the top of the upper cover body 2, one end of the first spring telescopic rod 222 is connected to the top of the bracket 221, and the other end of the first spring telescopic rod 222 is connected to the upper end of the vertical plate 21. One end of the first linear drive 23 is connected to the middle of the top of the upper cover body 2, and the other end of the first linear drive 23 is connected to the heat sealing machine body 1. The first linear drive 23 can be selected as a hydraulic rod. After the upper heat sealing block 11 and the lower heat sealing block 12 clamp the heat-sealed material, the first linear drive 23 pushes the upper cover body 2 downward, and the upper cover body 2 drives the vertical plate 21 to move downward, thereby realizing the surrounding of the upper heat sealing block 11.

[0057] Reference Figure 3 and Figure 8 As shown: the gas drive device 4 includes an inner cover body 41 which is arranged on the four sides of the upper heat sealing block 11 and is slidably connected to the upper cover body 2, a gas drive mechanism 42 which can be pulled and driven to flow gas is arranged inside the inner cover body 41, a partition plate 43 for separating the upper and lower parts of the inner cover body 41 is arranged at the air inlet end of the gas drive mechanism 42, a second linear drive 44 which can lift the inner cover body 41 up and down is arranged at the upper end of the inner cover body 41, and a gas guide structure 45 which is connected to the upper part of the inner cover body 41 is arranged outside the inner cover body 41.

[0058] The inner cover body 41 is provided with long strip-shaped air inlets on both sides of the upper heat sealing block 11. When the upper heat sealing block 11 and the lower heat sealing block 12 are working, toxic substances are generated. The gas driving mechanism 42 works to form a low-pressure area in the upper part of the inner cover body 41. The high-pressure gas in the lower part of the inner cover body 41 flows to the low-pressure area, thereby drawing the toxic substances in the degassing cavity into the inner cover body 41, and the toxic gas is directed to the purification and filtering device through the air guide structure 45. The long strip-shaped air inlet can inhale more toxic gas in a short time, thereby improving the efficiency of discharging the toxic gas from the degassing cavity.

A synchronously working linkage mechanism 53 is arranged between the upper sealing mechanism 51 and the lower sealing mechanism 52. The upper sealing mechanism 51 and the lower sealing mechanism 52 seal the gap between the front end of the upper cover body 2 and the front end of the lower cover body 3.

[0060] The vertical plate 21 moves downward, driving the upper sealing mechanism 51 to move toward the lower sealing mechanism 52 until the upper sealing mechanism 51 and the lower sealing mechanism 52 clamp the heat-sealed material, thereby achieving a sealing effect between the vertical plate 21, the heat-sealed material and the lower cover body 3, thereby preventing toxic substances from flowing out of the gap between the vertical plate 21, the heat-sealed material and the lower cover body 3.

[0062] A sliding groove is provided in the middle of the upper support arm 512, and the upper support arm 512 is slidably connected to the upper connecting seat 513. An upper elastic baffle is provided on the side of the upper sealing roller 511, and the upper elastic baffle is tightly pressed against the upper sealing roller 511. When the vertical plate 21 moves downward to a certain position, the upper sealing roller 511 is tightly pressed against the side wall of the upper heat sealing block 11, and the driving mechanism 515 pushes the first connecting rod 514 to drive the upper support arm 512 to slide on the upper connecting seat 513, so that the upper sealing roller 511 gradually moves outward until it clamps the heat-sealed material with the lower sealing mechanism 52, thereby realizing the sealing between the upper sealing roller 511 and the heat-sealed material.

A lower elastic baffle is provided on the side of the lower sealing roller 521, and the lower elastic baffle is tightly pressed against the lower sealing roller 521, and the lower sealing roller 521 is tightly pressed against the side wall of the lower heat sealing block 12. When the driving mechanism 515 pushes the first connecting rod 514, the second connecting rod 524 is driven to move through the linkage mechanism 53, so that the second connecting rod 524 drives the lower supporting arm 522 to slide on the lower connecting seat 523, so that the upper sealing roller 511 gradually moves outward from the contact point with the lower heat sealing block 12 until the lower sealing roller 521 and the upper sealing roller 511 clamp the heat-sealing material, thereby realizing the sealing between the lower sealing roller 521 and the heat-sealed material.

[0065] Reference Figure 5 and Fig. 9 As shown: the linkage mechanism 53 includes an upper connecting rod 531 connected to the first connecting rod 514 and a lower connecting rod 532 connected to the second connecting rod 524, a sliding connection seat 533 for connection is provided between the upper connecting rod 531 and the lower connecting rod 532, a sliding rod 534 is provided in the middle of the sliding connection seat 533, one end of the sliding rod 534 is connected to the lower cover body 3 through a support frame 535, and a pressure spring 536 is sleeved on the sliding rod 534. .

When the driving mechanism 515 drives the first connecting rod 514, the first connecting rod 514 drives the upper connecting rod 531, and the upper connecting rod 531 transmits power to the sliding connection block. The sliding connection block slides on the slide to drive the lower connecting rod 532, and the lower connecting rod 532 drives the second connecting rod 524 to move, thereby realizing the synchronous movement of the upper sealing roller 511 and the lower sealing roller 521, and the gas between the heat-sealed materials is discharged, and then the heat-sealed materials can be directly pulled out after the heat-sealing is completed, and the heat-sealed materials will not be damaged due to the gas inside the heat-sealed materials.
