[0012] Preferably, the surface of the heating chamber is connected to a valve; the valve is located at the top of the heating chamber; by adding a valve, the heat flow rate inside the heating chamber can be accelerated, thereby accelerating the heat dissipation.
[0013] The advantages of this utility model are:
[0014] 1. The filter paper cutting device of this utility model first heats the inside of the heating box with a heating rod, and then uses the heat inside the heating box to quickly heat up the cutter before cutting the filter paper.

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a filter paper cutting device includes a workbench 1, a heating box 13 fixedly connected to the surface of the workbench 1; a cylinder 11 fixedly connected to the side wall of the workbench 1; a cutter 12 fixedly connected to the output end of the cylinder 11; the cutter 12 is located inside the heating box 13; the cutter 12 is slidably connected to the workbench 1; a pair of door panels 14 are rotatably connected to the inner wall of the heating box 13; the door panels 14 and the heating box 13 are connected by torsion springs; and multiple heating elements are fixedly connected inside the heating box 13. A heating rod 15 is used; a support frame 16 is fixedly connected to the end of the worktable 1; a pressure roller 17 is rotatably connected to the middle of the support frame 16; during operation, filter paper is first fed into the worktable 1 surface from below the pressure roller 17. As the filter paper moves, the pressure roller 17 rotates and presses the filter paper down close to the worktable 1 surface. The filter paper then continues to move, passing the cutter 12, and is adjusted to the required length along the cutter 12's movement path. The movement of the filter paper activates the heating rod 15, causing the heating chamber 13 to heat up rapidly. Heating the cutter 12, after the filter paper is adjusted, the cylinder 11 is activated to move the cutter 12. When the cutter 12 moves, it will contact the door panel 14, at which point the door panel 14 will rotate, opening the heating chamber 13. At this time, the cylinder 11 pushes the cutter 12 to quickly cut the filter paper using its end. During the cutting process, the high temperature of the cutter 12 will melt the cut thread ends, causing them to shrink back onto the filter paper. After the cutter 12 has finished cutting the filter paper, the cylinder 11 will retract the cutter 12 into the heating chamber 13, and the door panel will close simultaneously. The angle of the 14 will also change, so that the heating box 13 is opened and the cutter 12 enters the heating box 13 for heating. By first heating the inside of the heating box 13 with the heating rod 15, and then using the heat inside the heating box 13 to quickly heat up the cutter 12 and finally cut the filter paper, the thread ends after the filter paper is cut can be reduced, thereby increasing the cutting effect and reducing the subsequent processing time. At the same time, when the filter paper moves, the pressure roller 17 will press the filter paper down to fit as close as possible to the worktable 1, thereby increasing the flatness of the cutter 12 during cutting.
[0026] like Figures 1 to 3As shown, multiple support plates 2 are fixedly connected to the surface of the workbench 1; the spacing between the support plates 2 is the same; a slide rod 21 is slidably connected inside the support plate 2; a pressure plate 23 is fixedly connected to the bottom of the slide rod 21; a spring 22 is fixedly connected between the pressure plate 23 and the support plate 2; during operation, when moving the end of the filter paper, it can be fixed by the adjacent pressure plate 23 when it needs to be stopped. When using the pressure plate 23 to fix the filter paper, the slide rod 21 can be pulled first to compress the spring 22. At this time, the filter paper is placed at the bottom of the pressure plate 23, and then the slide rod 21 is released. At this time, the spring 22 will immediately... The springback causes the pressure plate 23 to be pressed down quickly, and finally the pressure plate 23 will squeeze and fix the filter paper. At this time, the cutter 12 can be used to cut the filter paper. At the same time, the length of the filter paper can be quickly positioned according to the distance between the support plates 2, so that the corresponding pressure plate 23 can be used to fix it quickly. By adding the pressure plate 23, the contact between the filter paper and the worktable 1 can be increased when cutting the filter paper, thereby reducing the bevel when the cutter 12 cuts, thus increasing the stability of the filter paper during cutting. At the same time, the distance between the support plates 2 is fixed, so the position of the filter paper can be directly confirmed by the position of the support plate 2 when the filter paper moves.
[0027] like Figures 1 to 4 As shown, a collection trough 3 is provided in the middle of the workbench 1; the collection trough 3 and the cutter 12 are correspondingly arranged; a pair of round rods 31 are fixedly connected to the top of the workbench 1; a scraper 32 is rotatably connected to the surface of the round rods 31; the end of the scraper 32 is set with an inclined surface; the scraper 32 and the round rods 31 are connected by a torsion spring; during operation, when the cutter 12 cuts the filter paper, since the filter paper is made of cotton thread, some of the loose thread ends will be melted by the cutter 12 and finally adhere to the surface of the cutter 12. After the cutter 12 has completely cut the filter paper, it will enter the... Above the collection trough 3, the end of the cutter 12 will first enter the middle of the scraper 32, and the surface of the cutter 12 will contact the scraper 32 to clean the thread attached to the surface of the cutter 12. When the cutter 12 leaves the collection trough 3, the scraper 32 will return to its initial position due to the torsion spring, and the scraped thread will also enter the collection trough 3. By adding the scraper 32, the thread attached to the surface of the cutter 12 can be reduced, causing it to fall into the collection trough 3, thereby reducing the impact of the thread attached to the surface of the cutter 12 on the cutting process.
[0028] like Figure 1 As shown, a ruler 4 is fixed to the top of the workbench 1; the ruler 4 and the support plate 2 are set accordingly; during operation, when the filter paper is moved, the position value of the support plate 2 can be seen intuitively through the ruler 4, so as to determine which position of the support plate 2 the end of the filter paper is connected to; by adding the ruler 4, the support plate 2 can be assisted in judging the length of the filter paper, thereby reducing the time spent in determining the length and thus speeding up the adjustment of the filter paper.
[0029] like Figure 5 As shown, an air jet pipe 5 is fixedly connected to the side wall of the support frame 16; the air jet pipe 5 is multi-hole; an air guide pipe 51 is fixedly connected to the top of the support frame 16; the air guide pipe 51 and the air jet pipe 5 are connected; during operation, when the filter paper moves through the pressure roller 17, the air guide pipe 51 is connected to an air pump to transmit airflow through the air guide pipe 51 to the inside of the air jet pipe 5 and finally spray it onto the surface of the filter paper. At this time, the impurities attached to the surface of the filter paper can be removed, thereby reducing the impact of impurities on the cutter 12; by adding the air jet pipe 5, the impurities on the surface of the filter paper can be reduced, thereby increasing the effect of the cutter 12 on the filter paper cutting.
[0030] like Figure 1 As shown, the heating box 13 has a valve 6 connected to its surface; the valve 6 is located at the top of the heating box 13; during operation, the valve 6 can be used to quickly release the heat inside the heating box 13 after the cutter 12 is no longer needed, thereby accelerating the cooling speed of the cutter 12; by adding the valve 6, the heat flow rate inside the heating box 13 can be accelerated, thereby accelerating the heat discharge.
[0031] Working principle: Filter paper is first fed from below the pressure roller 17 onto the surface of the worktable 1. As the filter paper moves, the pressure roller 17 rotates, pressing the filter paper down close to the worktable 1 surface. It then continues to move past the cutter 12, adjusting the filter paper to the required length along the cutter 12's path. The movement of the filter paper activates the heating rod 15, rapidly heating the interior of the heating chamber 13 to heat the cutter 12. Once the filter paper is adjusted, the cylinder 11 pushes the cutter 12. As the cutter 12 moves, it contacts the door panel 14, causing the door panel 14 to rotate and open the heating chamber 13. The cylinder 11 then pushes the cutter 12 forward, quickly... During filter paper cutting, the high temperature of the cutter 12 melts the cut thread ends, causing them to shrink onto the filter paper. After the cutter 12 has finished cutting the filter paper, the cylinder 11 retracts the cutter 12 into the heating chamber 13, and the door panel 14 also changes angle, opening the heating chamber 13 to allow the cutter 12 to enter and be heated. When moving the filter paper end, it can be fixed by the nearby pressure plate 23 when it needs to be stopped. To fix the filter paper using the pressure plate 23, first pull the slide rod 21 to compress the spring 22, then place the filter paper at the bottom of the pressure plate 23. Then release the slide rod 21, and the spring 22 will immediately rebound, thus fixing the pressure plate. 23. Press down quickly, and the pressure plate 23 will squeeze and fix the filter paper. At this time, use the cutter 12 to cut the filter paper. At the same time, the length of the filter paper can be quickly positioned according to the distance between the support plates 2, so that the corresponding pressure plate 23 can be used to fix it. When the cutter 12 cuts the filter paper, since the filter paper is made of cotton thread, some of the loose thread will be melted by the cutter 12 and finally adhere to the surface of the cutter 12. When the cutter 12 has completely cut the filter paper, it will enter the upper part of the collection tank 3. At this time, the end of the cutter 12 will first enter the middle of the scraper 32, and the surface of the cutter 12 will contact the scraper 32 to clean the thread attached to the surface of the cutter 12. When the cutter 12 leaves the scraper 32, the cutter 12 will be cleaned. After the collection trough 3 is opened, the scraper 32 will return to its initial position due to the torsion spring, and the scraped thread will also enter the collection trough 3. When the filter paper is moved, the position value of the support plate 2 can be seen intuitively through the scale 4, so as to determine which position of the support plate 2 the end of the filter paper is connected to. When the filter paper moves through the pressure roller 17, the air guide pipe 51 is connected to the air pump to transmit the airflow through the air guide pipe 51 to the inside of the jet pipe 5 and finally spray it onto the surface of the filter paper. At this time, the impurities attached to the surface of the filter paper can be removed, thereby reducing the impact of impurities on the cutter 12. When the cutter 12 is no longer needed, the heat inside the heating box 13 can be quickly released by the valve 6, thereby accelerating the cooling speed of the cutter 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
