Description

Technical Field

[0001] This utility model relates to the field of exhaust technology for heat sealing machines, and in particular to an exhaust mechanism for a plastic heat sealing machine. Background Technology

[0002] A plastic heat sealing machine is a device used to fuse two or more sheets of plastic film together by heating and pressurizing. It is widely used in the packaging industry, such as in the manufacture of packaging bags for food, pharmaceuticals, and daily necessities. The heat sealing process typically involves high temperatures to bring the plastic materials to their melting point and bond them together, but this process may generate some harmful gases and fine particulate matter.

[0003] To protect the health of operators and maintain a good working environment, plastic heat sealing machines are usually equipped with exhaust systems to extract these harmful substances and release them into the atmosphere after treatment.

[0004] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Existing exhaust systems typically include a filtration step to remove particulate matter and other pollutants from exhaust gases. However, over time, dust and impurities gradually accumulate on the filter plates, leading to a decrease in filtration efficiency, and frequent cleaning operations increase downtime. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that in the prior art, the filter plate will gradually accumulate dust and impurities, resulting in a decrease in filtration efficiency, and frequent cleaning operations will increase downtime. To address this, we propose an exhaust mechanism for a plastic heat sealing machine.

[0006] To achieve the above objectives, this application adopts the following technical solution: an exhaust mechanism for a plastic heat sealing machine, comprising: a workbench, a first connecting pipe provided below the workbench, a filter box fixedly connected to one end of the first connecting pipe, an exhaust fan provided on one side of the filter box, a filter plate provided inside the filter box, a dust discharge box fixedly connected to the bottom of the filter box, and an anti-clogging component provided on one side of the filter plate.

[0007] The anti-clogging component includes an electric push rod installed at the top of the filter box, a mounting plate located at the telescopic end of the electric push rod, a brush installed on one side of the mounting plate, a first connecting block fixedly connected to the bottom of the mounting plate, a cleaning block located inside the dust collection box, a second connecting block fixedly connected to the top of the cleaning block, and a movable rod hinged between the second connecting block and the first connecting block. There are two sets of cleaning blocks, movable rod, and second connecting blocks. The two sets of cleaning blocks are symmetrically arranged about the first connecting block. The telescopic end of the electric push rod moves through the filter box. The brush contacts the outer surface of the filter plate. A cleaning scraper is fixedly connected to one side of the cleaning block. The cleaning scraper contacts the inner wall of the dust collection box.

[0008] Preferably, the dust discharge box has a dust discharge port at the bottom, a slider is slidably connected to the inner wall of the dust discharge port, a positioning plate is fixedly connected to the bottom of the slider, and the top of the slider is fixedly connected to the cleaning block.

[0009] Preferably, a limiting groove is provided at the top of the mounting plate, a limiting plate is fitted inside the limiting groove, a mounting block is fixedly connected to the top of the limiting plate, the mounting block is fixedly connected to the telescopic end of the electric push rod, and a first locking bolt is threaded between the limiting plate and the limiting groove.

[0010] Preferably, a door is provided on one side of the filter box, and a second locking bolt is threadedly connected between the door and the filter box. A support leg is fixedly connected to the bottom of the filter box.

[0011] Preferably, the inner wall of the filter box is provided with a sliding groove, and the filter plate is slidably connected to the sliding groove.

[0012] Preferably, the input end of the exhaust fan is fixedly connected to an air inlet pipe, the output end of the exhaust fan is fixedly connected to an air outlet pipe, the air inlet pipe is fixedly connected to the filter box, the top of the workbench is provided with an air outlet, the air outlet is provided with an exhaust pipe, and the exhaust pipe is fixedly connected to the first connecting pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The main innovation of this invention lies in its simple working principle. The filter plate effectively intercepts dust and impurities in the exhaust gas, improving air purification. When a large amount of dust accumulates on the outer surface of the filter plate, an electric push rod moves the mounting plate up and down, causing the brush to reciprocate along the outer surface of the filter plate, promptly removing dust, reducing clogging, maintaining filtration efficiency, and reducing equipment downtime caused by manual cleaning. The design of the cleaning blocks and movable rods allows the cleaning scraper to clean the inner wall of the dust collection box simultaneously, preventing dust accumulation and secondary pollution. The two sets of cleaning blocks are symmetrically arranged, and under the linkage of the two sets of movable rods, they can move in the same or opposite directions, which facilitates improved cleaning coverage. This solves the problem in the prior art where the filter plate gradually accumulates dust and impurities, leading to a decrease in filtration efficiency, and frequent cleaning operations increase downtime.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Reference Figures 1-2 and Figure 4 As shown, this utility model provides a technical solution: an exhaust mechanism for a plastic heat sealing machine, comprising: a workbench 1, a first connecting pipe 8 provided below the workbench 1, a filter box 3 fixedly connected to one end of the first connecting pipe 8, an exhaust fan 2 provided on one side of the filter box 3, a filter plate 4 provided inside the filter box 3, a dust discharge box 6 fixedly connected to the bottom of the filter box 3, and an anti-clogging component 5 provided on one side of the filter plate 4.

[0026] Reference Figures 1-7 As shown in this embodiment: the anti-clogging component 5 includes an electric push rod 51 installed at the top of the filter box 3, a mounting plate 52 set at the telescopic end of the electric push rod 51, a brush 53 installed on one side of the mounting plate 52, a first connecting block 54 fixedly connected to the bottom of the mounting plate 52, a cleaning block 55 set inside the dust collection box 6, a second connecting block 56 fixedly connected to the top of the cleaning block 55, and a movable rod 57 hinged between the second connecting block 56 and the first connecting block 54. Two sets of cleaning blocks 55, movable rod 57 and second connecting block 56 are provided. The two sets of cleaning blocks 55 are symmetrically arranged about the first connecting block 54. The telescopic end of the electric push rod 51 moves through the filter box 3. The brush 53 contacts the outer surface of the filter plate 4. A cleaning scraper 551 is fixedly connected to one side of the cleaning block 55. The cleaning scraper 551 contacts the inner wall of the dust collection box 6. The filter plate 4 effectively intercepts dust and impurities in the exhaust, improving air purification. When a lot of dust accumulates on the outer surface of the filter plate 4, the electric push rod 51 drives the mounting plate 52 to move up and down, causing the brush 53 to reciprocate along the outer surface of the filter plate 4 to remove dust in time, reduce clogging, maintain filtration efficiency, and reduce equipment downtime caused by manual cleaning. The design of the cleaning block 55 and the movable rod 57 allows the cleaning scraper 551 to clean the inner wall of the dust box 6 simultaneously, preventing dust accumulation and secondary pollution. The two sets of cleaning blocks 55 are symmetrically arranged, and the two sets of cleaning blocks 55 can move in the same or opposite directions under the linkage of the two sets of movable rods 57, which facilitates the improvement of cleaning coverage.

[0027] The dust collection box 6 has a dust discharge port 61 at its bottom. A slider 611 is slidably connected to the inner wall of the dust discharge port 61. A positioning plate 6111 is fixedly connected to the bottom of the slider 611, and the top of the slider 611 is fixedly connected to the cleaning block 55. The dust discharge port 61 is located at the bottom of the dust collection box 6, so that the dust swept down by the cleaning scraper 551 can fall smoothly into the dust discharge port 61 and be discharged. The top of the slider 611 is fixedly connected to the cleaning block 55, and the bottom is limited by the positioning plate 6111. When the electric push rod 51 drives the mounting plate 52 to move up and down, it provides guidance for the movement of the cleaning block 55 and the cleaning scraper 551.

[0028] A limiting groove 521 is formed at the top of the mounting plate 52. A limiting plate 7 is fitted inside the limiting groove 521. A mounting block 72 is fixedly connected to the top of the limiting plate 7. The mounting block 72 is fixedly connected to the telescopic end of the electric push rod 51. A first locking bolt 71 is threaded between the limiting plate 7 and the limiting groove 521. The first locking bolt 71 facilitates the fixing of the limiting plate 7 and the limiting groove 521, thereby fixing the electric push rod 51 and the mounting plate 52. Removing the first locking bolt 71 facilitates the removal of the mounting plate 52 for cleaning the brush 53.

[0029] A door 31 is provided on one side of the filter box 3. A second locking bolt 311 is threadedly connected between the door 31 and the filter box 3. A support leg 32 is fixedly connected to the bottom of the filter box 3. When it is necessary to replace the filter plate 4 or inspect the anti-clogging component 5, the door 31 can be opened simply by removing the second locking bolt 311, so as to achieve full contact with the internal structure of the filter box 3 and improve maintenance efficiency.

[0030] The inner wall of the filter box 3 is provided with a sliding groove 33, and the filter plate 4 is slidably connected to the sliding groove 33. The sliding connection between the sliding groove 33 and the filter plate 4 makes it easy for the operator to pull out or insert the filter plate 4 along the direction of the sliding groove 33.

[0031] An inlet pipe 21 is fixedly connected to the input end of the exhaust fan 2, and an outlet pipe 22 is fixedly connected to the output end of the exhaust fan 2. The inlet pipe 21 is fixedly connected to the filter box 3. An outlet 11 is provided at the top of the workbench 1, and an exhaust pipe 111 is provided inside the outlet 11. The exhaust pipe 111 is fixedly connected to the first connecting pipe 8. The outlet 11 and exhaust pipe 111 at the top of the workbench 1, through the forced suction of the exhaust fan 2, facilitate the rapid intake of smoke and exhaust gas generated during the plastic heat sealing process from the work area, and after purification by the filter box 3, they are discharged, which helps to improve the air quality in the workshop and establishes a complete airflow path from the workbench 1 to the filter box 3 and then to the exhaust fan 2.

[0032] Working principle: The forced suction of the exhaust fan 2 allows the smoke and exhaust gas generated during the plastic heat sealing process to be quickly drawn from the working area and into the filter box 3. The filter plate 4 effectively intercepts dust and impurities in the exhaust, improving the air purification effect. When a lot of dust accumulates on the outer surface of the filter plate 4, the electric push rod 51 drives the mounting plate 52 to move up and down, causing the brush 53 to reciprocate along the outer surface of the filter plate 4 to remove dust in time, reduce clogging, maintain filtration efficiency, and reduce equipment downtime caused by manual cleaning. The design of the cleaning block 55 and the movable rod 57 allows the cleaning scraper 551 to clean the inner wall of the dust box 6 simultaneously, preventing dust accumulation and secondary pollution. The two sets of cleaning blocks 55 are symmetrically arranged, and the two sets of cleaning blocks 55 can move in the same or opposite directions under the linkage of the two sets of movable rods 57, which can improve the cleaning coverage. When it is necessary to replace the filter plate 4 or check the anti-clogging component 5, simply remove the second locking bolt 311 to open the box door 31, so as to achieve full contact with the internal structure of the filter box 3 and improve maintenance efficiency.
