Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite filter material finishing, in particular to an active carbon air conditioner filter core assembling equipment. BACKGROUND

[0002] The assembling process of the active carbon air conditioner filter core is usually divided into manual assembling and automatic production line assembling, and the core principle is to use the support frame, the primary / medium efficiency filter layer and the active carbon layer to jointly complete air filtration. The current mainstream way is automatic production line assembling, and the assembling process includes: preparing materials, filter material compounding and cutting, frame assembling and filter material installation, installing sealing strips and quality inspection.

[0003] The specific steps of the above filter material compounding and cutting are: multiple layers of filter material (such as primary efficiency layer + active carbon layer + HEPA layer) are compounded into one whole body through a roller pressing equipment, and the compounded filter material is cut into the required shape and size through a stamping die, and the surface tension of the filter material needs to be maintained within a certain range during stamping and cutting. If the tension is too small, the filter material is easy to wrinkle, affecting the material accuracy after punching, and also making it difficult for the punching die to cut off the filter material. If the tension is too large, the filter material is easy to be pulled too hard, causing the filter material to deform or even tear, damaging the internal structure of the filter material and directly affecting the filtering effect of the filter material. In the process of continuous punching of the filter material, the source of the surface tension of the filter material is the pressure roller and the waste collecting roller. The pressure roller controls the surface tension of the filter material through the contact area with the filter material, and the collecting roller controls the surface tension of the filter material through the collecting speed.

[0004] When the above collecting roller continuously collects the waste after punching, the waste is rolled thicker and thicker on the collecting roller, so that the linear speed of the outermost waste continuously increases, and therefore the surface tension of the filter material exerted by the collecting roller continuously increases. At the same time, with the collection of the waste, the effective radius of the collecting roller increases, so that the filter material inclination angle between the pressure roller and the collecting roller increases, the area of the filter material covering the pressure roller increases, and the surface tension of the filter material exerted by the pressure roller continuously increases, thereby directly affecting the punching effect of the filter material and also affecting the use quality of the filter material.

[0005] According to the search, Chinese patent application CN116766609A discloses an air conditioner filter element assembling equipment, which cannot solve the above problems, so that the surface tension of the filter material cannot be always stabilized in a specific range, the punching efficiency cannot be guaranteed, and the quality of the filter material and the punching quality cannot be guaranteed, and different thicknesses of the filter material require different punching pressures and punching speeds, for example, if the thickness of the filter material increases, the punching pressure needs to be correspondingly increased, and the punching speed needs to be reduced or maintained, because thicker material needs more force to completely cut off, and reducing the speed can give the force more time to transfer to the bottom of the material to achieve a clean and neat cut, avoid the bottom material from being squeezed and pulled due to insufficient force, and punching is usually driven by a hydraulic cylinder, and the output speed of the hydraulic cylinder should be faster under high pressure, which cannot meet the punching requirements of the filter material.

[0014] As a further embodiment of the present invention: the rotating shaft is rotatably connected to the second fixed fixture, the pull rod is slidably sleeved to the end of the transmission shaft, the effective diameter of the multi-stage gear gradually decreases, the effective diameter of the gear plate gradually increases, the transmission gear and the rack are both located in the fixed frame, the rack is fixedly connected to the bottom surface of the first slide groove, and the transmission gear is slidably connected to the first slide groove.

[0015] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows:

[0016] 1. This invention uses a baffle to obstruct the take-up roller. As the filter media waste continues to curl onto the take-up roller, the effective radius of the take-up roller increases, causing the take-up roller and filter media waste to continuously press against the baffle. The baffle remains fixed, causing the take-up roller and crossbar to move along the first groove under the action of the reaction force. This keeps the filter media inclination angle between the take-up roller and the second pressure roller constant, keeps the area of ​​the filter media covering the second pressure roller constant, and keeps the surface tension applied by the second pressure roller to the filter media constant. Simultaneously, as the crossbar moves along the first groove, the lead screw on the crossbar drives the transmission gear synchronously. The rack, which meshes with the transmission gear, is fixed to the first groove, causing the transmission gear to slide and rotate simultaneously. This rotation of the transmission gear, in turn, drives the lead screw to rotate. The third slider on the lead screw is restricted from rotating by the second groove, causing it to translate under the rotation of the lead screw. This, in turn, causes the connecting rod on the third slider to translate the pull rod, which in turn causes the insert on the pull rod to translate. This allows the insert to engage with the smaller-radius multi-stage gear, ensuring that the transmission shaft can only drive the smaller-radius multi-stage gear to rotate. According to the linear velocity formula... It can be seen that when the transmission speed of the electric motor, i.e., the angular velocity w, is constant, the smaller the radius r, the smaller the linear velocity v. Therefore, the linear velocity of the toothed disc driven by the multi-stage gear decreases, while the effective radius of the toothed disc corresponding to the multi-stage gear with a smaller radius is larger. According to the angular velocity formula... As can be seen, a decrease in linear velocity leads to an increase in radius and a smaller angular velocity. Consequently, the rotational speeds of the gear disc, shaft, and drive belt decrease, indirectly reducing the angular velocity of the take-up roller. In summary, the thicker the filter media waste material wound on the take-up roller, the smaller the angular velocity of the take-up roller. This balances the increase in linear velocity on the outermost side of the take-up roller, ensuring a constant linear velocity of the filter media driven by the take-up roller. This, in turn, ensures a constant surface tension applied to the filter media by the take-up roller. Therefore, during the filter media trimming process, its surface tension can be stabilized within a specific range, thus guaranteeing the punching effect of the filter media, further ensuring the quality of the filter media, and improving punching efficiency.

[0017] 2. This invention raises the first slider by the filter media, causing the laser rangefinder on the first slider to shift. This allows the laser rangefinder to automatically detect the thickness of the filter media and transmit the thickness value to the controller. The controller then activates the first pressure pump based on the thickness value. The first pressure pump draws external liquid through a conduit and delivers it to the distribution chamber. The liquid is then distributed to both ends of the cylinder via a distribution channel, increasing the hydraulic pressure at both ends of the cylinder. During this process, the hydraulic pressure at the upper and lower ends of the piston rod is balanced until the hydraulic pressure reaches a value matching the thickness of the filter media. At this point, the controller restarts... The second pressure pump is activated, and the opening of the pressure valve is adjusted according to the thickness of the filter media. This allows the second pressure pump to draw the liquid from the lower end of the cylinder into the connecting channel and deliver it to the upper end of the cylinder at a constant flow rate. This causes the piston rod in the cylinder to descend at a specific speed, which in turn causes the punching die on the piston rod to descend at a specific speed until the punching die cuts the filter media. This ensures that the thickness of the filter media corresponds to the punching pressure and punching speed, which can accommodate the trimming of filter media of various thicknesses. It also prevents the filter media from re-layering and avoids the compaction of the filter media edges, thus avoiding increased air resistance in that area and ensuring the uniformity of airflow in the air conditioning filter element.

[0018] 3. The punching pressure of the present invention is increased, and the piston rod will not move. The descent of the piston rod is only controlled by the second pressure pump and the opening of the pressure valve, so that the punching speed and punching pressure can be controlled separately, which can meet the punching requirements of various filter materials.

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1, please refer to Figures 1-3 and Figure 5 This invention provides a technical solution: an assembly device for activated carbon air conditioning filters, comprising a body 1, a controller 2 mounted on the side wall of the body 1, and a bracket 3 fixedly connected to the top surface of the body 1. A first slider 4 is slidably connected to the bracket 3, and the first slider 4 is fixedly connected to the bracket 3 by fastening bolts 5. Both the bracket 3 and the first slider 4 are provided in two sets. A first pressure roller 6 is rotatably connected between one set of first slider 4, and a second pressure roller 7 is rotatably connected between the other set of first slider 4. A worktable 8 is fixedly connected to the top surface of the body 1. A cylinder 9 is mounted on the top surface of the workbench 8. A liquid distribution chamber 10 is opened in the top wall of the cylinder 9. A first pressure pump 11 is connected to the top surface of the liquid distribution chamber 10. A conduit 12 is connected to the input end of the first pressure pump 11. A flow distribution channel 13 and a connecting channel 15 are opened in the side wall of the cylinder 9. A one-way valve 14 is installed at the end of each flow distribution channel 13. A second pressure pump 16 is connected to the side wall of the connecting channel 15. One end of a piston rod 17 is slidably sleeved in the cylinder 9. A punching die 18 is fixedly connected to the other end of the piston rod 17.

[0031] Please see Figure 2 and Figure 3The flow channel 13 is connected to the liquid distribution chamber 10. Both ends of the flow channel 13 and the connecting channel 15 are connected to both ends of the cylinder 9. The one-way valve 14 prevents the liquid in the cylinder 9 from flowing back. The first pressure pump 11 and the second pressure pump 16 are both electrically connected to the controller 2. The output end of the second pressure pump 16 is equipped with a pressure valve. The opening degree of the pressure valve is controlled by the controller 2. The punching die 18 is slidably connected to the worktable 8.

[0032] Please see Figure 1 and Figure 5 The first pressure roller 6 and the second pressure roller 7 are located on both sides of the blanking die 18, and the outer surfaces of the first pressure roller 6 and the second pressure roller 7 are tangent to the bottom surface of the parting surface of the blanking die 18. A laser range sensor is installed on the top surface of the first slider 4, and the laser range sensor is electrically connected to the controller 2.

[0033] Specifically, during the blanking process of the filter material, the fastening bolt 5 on the rotating bracket 3 releases the bracket 3 from the first slider 4, allowing the first pressure roller 6 and the second pressure roller 7 on the first slider 4 to rise and fall. This stretches the filter material on the unwinding machine, causing it to pass sequentially through the first pressure roller 6 and the second pressure roller 7. Rotating the fastening bolt 5 re-fixes the first pressure roller 6 and the second pressure roller 7 on the first slider 4, ensuring the filter material between the first pressure roller 6 and the second pressure roller 7 is straight. Finally, the filter material is rolled onto the take-up roller 30, completing the preparation work. During this process, the filter material passing through the first pressure roller 6 and the second pressure roller 7 causes the first slider 4 to rise, displacing the laser rangefinder on the first slider 4. This allows the laser rangefinder to automatically detect the thickness of the filter material and transmit the thickness value to the controller 2. The controller 2 then activates the first pressure pump 11 based on the thickness value. The first pressure pump 11 then draws external liquid through the conduit 12 and delivers it to the dispensing chamber 10, where it is then... The diversion channel 13 delivers liquid to both ends of the cylinder 9, increasing the hydraulic pressure at both ends of the cylinder 9. During this process, the hydraulic pressure at the upper and lower ends of the piston rod 17 is balanced until the hydraulic pressure value reaches a value that matches the thickness of the filter media. At this time, the controller 2 starts the second pressure pump 16 and adjusts the opening of the pressure valve according to the thickness of the filter media. This allows the second pressure pump 16 to draw the liquid from the lower end of the cylinder 9 into the connecting channel 15 and deliver it to the upper end of the cylinder 9 at a constant flow rate. This causes the piston rod 17 in the cylinder 9 to descend at a specific speed, and the punching die 18 on the piston rod 17 to descend at a specific speed until the punching die 18 cuts the filter media. This ensures that the thickness of the filter media corresponds to the punching pressure and punching speed, which can adapt to the trimming of filter media of various thicknesses, avoids the re-layering of the filter media, avoids the compaction of the filter media edges, avoids increasing the wind resistance in this area, and ensures the uniformity of air circulation in the air conditioning filter element. The cylinder 9, the liquid distribution chamber 10, the diversion channel 13, and the connecting channel 15 are filled with hydraulic oil (such as ISO). VG46 hydraulic oil has a viscosity of 46 cSt (40°C) and a compression ratio of less than 0.8%, ensuring rapid system response and high stability.

[0034] In this embodiment, the controller 2 adjusts the operating parameters of the first pressure pump 11 and the second pressure pump 16 according to the filter material thickness value detected by the laser rangefinder sensor and through a preset control algorithm. The specific control logic is as follows:

[0035] Thickness-pressure relationship: The punching pressure P and the filter material thickness d satisfy a linear relationship. Where k1 is the pressure coefficient (range 0.5-1.5 MPa / mm), b1 is the reference pressure (range 0.1-0.5 MPa), the controller calculates the target pressure P based on the thickness value d and controls the first pressure pump 11 to output the corresponding hydraulic pressure;

[0036] Thickness-speed relationship: The punching speed v is inversely proportional to the filter material thickness d. Where k2 is the velocity coefficient (range 10-50 mm) 2 / s), the controller calculates the target speed v based on the thickness value d and controls the flow rate by adjusting the opening of the pressure valve of the second pressure pump 16 to achieve a specific descent speed of the piston rod 17;

[0037] Control algorithm: The controller uses a PID (proportional-integral-derivative) algorithm to adjust the pressure valve opening in real time to ensure stable punching speed. The PID parameters can be preset according to the filter material and thickness.

[0038] Laser displacement sensors with an accuracy of ±0.1 mm and a measuring range of 0-10 mm (such as the KEYENCE IL-100 series) can be selected to ensure accurate thickness detection.

[0039] The first pressure pump 11 and the second pressure pump 16 can be electric hydraulic pumps (such as PARKER PAVC series) with a rated pressure range of 0-10 MPa and a flow range of 0-5 L / min, and the pressure valve opening control accuracy is ±1%.

[0040] The filter material is an activated carbon composite filter material, including a non-woven pre-filter layer, an activated carbon adsorption layer, and a HEPA high-efficiency layer. The total thickness ranges from 0.5 to 5 mm, and the tensile strength is not less than 20 N / cm. The die 18 is designed for this thickness range, and the die-cutting pressure and speed are adjusted according to the above relationship.

[0041] Example 2, please refer to Figure 1 and Figures 4-6This invention provides a technical solution: an assembly device for activated carbon air conditioning filter elements. A fixing block 19 is fixedly connected to the top surface of the machine body 1. A first turntable 20 is rotatably connected to the side wall of the first slider 4. One end of a telescopic rod 21 is fixedly connected to the outer surface of the first turntable 20. The other end of the telescopic rod 21 is hinged to a second turntable 22. The second turntable 22 is rotatably connected to the fixing block 19. A baffle 23 is fixedly connected to the end of the telescopic rod 21. A fixing frame 24 is fixedly connected to the side wall of the machine body 1. A first sliding groove 25 is opened on the side wall of the fixing frame 24. A second slider 26 is slidably connected in the first sliding groove 25. A crossbar 27 is fixedly connected to the side wall of the second slider 26. A first fixing fixture 28 and a second fixing fixture 29 are fixedly connected to both ends of the crossbar 27. A gathering roller 30 is rotatably connected between the first fixing fixture 28 and the second fixing fixture 29.

[0042] Please see Figures 4-6 The central axis of the second turntable 22 coincides with the central axis of the initial position of the gathering roller 30. The diameter of the first turntable 20 is the same as the roller diameter of the second pressure roller 7, and the central axis of the first turntable 20 coincides with the central axis of the second pressure roller 7. The diameter of the second turntable 22 is the same as the roller diameter of the gathering roller 30. The telescopic rod 21 is tangent to the first turntable 20 and the second turntable 22. The baffle 23 is tangent to the second pressure roller 7 and the gathering roller 30. A return spring is provided between the end of the second slider 26 and the first slide groove 25.

[0043] Specifically, during the pressurization process, even if the punching pressure increases, the piston rod 17 will not move. The descent of the piston rod 17 is only controlled by the second pressure pump 16 and the opening of the pressure valve, so that the punching speed and punching pressure can be controlled separately, which can meet the punching requirements of various filter materials.

[0044] Example 3, please refer to Figures 6-9 This invention provides a technical solution: an assembly device for an activated carbon air conditioning filter element. A motor 31 is installed on the side wall of a second fixed fixture 29. A transmission shaft 32 is fixedly connected to the output end of the motor 31. A multi-stage gear 33 is sleeved on the outer surface of the transmission shaft 32. A gear disk 34 is meshed on the outer surface of the multi-stage gear 33. A rotating shaft 35 is fixedly connected to the central axis of the gear disk 34. One end of a transmission belt 36 is fixedly connected to the end of the rotating shaft 35. The other end of the transmission belt 36 is fixedly connected to a take-up roller 30. A cavity 37 is opened on the central axis of the transmission shaft 32. An insert 38 is fitted into the cavity 37. One end of a pull rod 39 is fixedly connected to the end face of the insert 38. A connecting rod 45 is rotatably connected to the other end of the pull rod 39. A lead screw 43 is rotatably sleeved at the end of a crossbar 27. A third slider 44 is meshed on one end of the lead screw 43. A transmission gear 41 is fixedly connected to the other end of the lead screw 43. A rack 42 is meshed on the outer surface of the transmission gear 41.

[0045] Please see Figure 8 and Figure 9The inner surface of the multi-stage gear 33 is provided with a groove 40, which is fitted and connected to the insert 38. The side wall of the crossbar 27 is provided with a second sliding groove 46, and the third slider 44 is slidably connected to the second sliding groove 46. The third slider 44 is fixedly connected to the end of the connecting rod 45.

[0046] Please see Figures 6-8 The rotating shaft 35 is rotatably connected to the second fixed fixture 29, the pull rod 39 is slidably sleeved to the end of the transmission shaft 32, the effective diameter of the multi-stage gear 33 gradually decreases, the effective diameter of the gear plate 34 gradually increases, the transmission gear 41 and the rack 42 are both located in the fixed frame 24, the rack 42 is fixedly connected to the bottom surface of the first slide groove 25, and the transmission gear 41 is slidably connected to the first slide groove 25.

[0047] Specifically, during the process of winding up the filter material waste, the rising of the first slider 4 will cause the first turntable 20 to rise, shortening the distance between the first turntable 20 and the second turntable 22. This causes the telescopic rod 21 to retract to accommodate the adjustment of the first slider 4. At the same time, the inclination angle of the telescopic rod 21 decreases, while the telescopic rod 21 remains tangent to the first turntable 20 and the second turntable 22, allowing the first turntable 20 and the second turntable 22 to rotate adaptively until the fastening bolt 5 re-fixes the first slider 4, thus fixing the inclination angle of the telescopic rod 21 and the baffle 23. At this point, the first slider 4 is then wound up again. The motor 31 on the fixed fixture 29 drives the drive shaft 32 on the motor 31 to rotate the insert 38 through the cavity 37. The insert 38 drives the multi-stage gear 33 with the largest diameter to rotate, which in turn drives the gear disk 34 to rotate. This causes the rotating shaft 35 on the gear disk 34 to drive the transmission belt 36 to rotate, which in turn drives the take-up roller 30 to rotate. As the take-up roller 30 continues to curl up the filter material waste, the effective radius of the take-up roller 30 increases, making the take-up roller 30 and the filter material waste more compact. The filter media waste continuously compresses the baffle 23, which remains fixed. This causes the gathering roller 30 and the crossbar 27 to move along the first groove 25 under the action of the reaction force. This keeps the filter media inclination angle between the gathering roller 30 and the second pressure roller 7 constant, keeps the area of ​​the filter media covering the second pressure roller 7 constant, and keeps the surface tension applied by the second pressure roller 7 to the filter media constant. Simultaneously, as the crossbar 27 moves along the first groove 25, the lead screw 43 on the crossbar 27 drives the transmission gear 41 to move synchronously. The rack 42, which meshes with the transmission gear 41, is fixedly connected to the first groove 25, thus... While the transmission gear 41 slides, it also rotates. This rotation of the transmission gear 41, in turn, drives the lead screw 43 to rotate. The third slider 44 on the lead screw 43 is restricted from rotating by the second groove 46, causing the third slider 44 to translate under the rotation of the lead screw 43. This, in turn, causes the connecting rod 45 on the third slider 44 to translate the pull rod 39, which in turn causes the insert 38 on the pull rod 39 to translate. This allows the insert 38 to engage with the multi-stage gear 33, which has a smaller radius. Therefore, the transmission of the drive shaft 32 can only drive the multi-stage gear 33, which has a smaller radius, to rotate. According to the linear velocity formula... It can be seen that when the transmission speed (angular velocity w) of the motor 31 is constant, the smaller the radius r, the smaller the linear velocity v. Therefore, the linear velocity of the toothed disk 34 driven by the multi-stage gear 33 decreases. Conversely, the effective radius of the toothed disk 34 corresponding to the smaller radius of the multi-stage gear 33 is larger. According to the angular velocity formula... As can be seen, a decrease in linear velocity leads to an increase in radius and a smaller angular velocity. Consequently, the rotational speeds of the gear disc 34, shaft 35, and drive belt 36 decrease, indirectly reducing the angular velocity of the take-up roller 30. In summary, the thicker the filter media waste material wound on the take-up roller 30, the smaller the angular velocity of the take-up roller 30. This balances the increase in linear velocity on the outermost side of the take-up roller 30, ensuring a constant linear velocity of the filter media driven by the take-up roller 30. This also ensures a constant surface tension applied to the filter media by the take-up roller 30. Therefore, during the filter media trimming process, its surface tension can be stabilized within a specific range, thus guaranteeing the punching effect of the filter media, further ensuring the quality of the filter media, and improving the punching efficiency.

[0048] In this embodiment, the multi-stage gear 33 can be a three-stage gear set with transmission ratios of i1=3:1, i2=2:1, and i3=1.5:1, respectively. The gear module is 1.5 mm. The switching trigger condition is that for every 5 mm increase in the radius of the gathering roller 30, the insert 38 shifts one stage, corresponding to a decrease in the radius of the multi-stage gear 33.

[0049] Telescopic pole 21 can be an electric telescopic pole with a stroke of 0-50 mm and a response time of less than 0.1 s.

[0050] The working principle and usage process of this invention are as follows: When filter material needs to be punched, the fastening bolt 5 on the rotating bracket 3 releases the bracket 3 from the first slider 4, allowing the first pressure roller 6 and the second pressure roller 7 on the first slider 4 to rise and fall. The filter material on the unwinding machine is then stretched, allowing it to pass sequentially through the first pressure roller 6 and the second pressure roller 7. The fastening bolt 5 is then rotated, re-fixing the first pressure roller 6 and the second pressure roller 7 on the first slider 4, ensuring the filter material between the first pressure roller 6 and the second pressure roller 7 is straight. Finally, the filter material is rolled onto the take-up roller 30, completing the preparation work. During this process, the filter material passing through the first pressure roller 6 and the second pressure roller 7 causes the first slider 4 to rise, displacing the laser rangefinder on the first slider 4. This allows the laser rangefinder to automatically detect the thickness of the filter material and transmit the thickness value to the controller 2. The controller 2 then activates the first pressure pump 11 based on the thickness value, thereby causing the first pressure pump 11 to... Pipe 12 draws in external liquid and delivers it to the liquid distribution chamber 10. Then, the liquid is delivered to both ends of the cylinder 9 by the distribution channel 13, increasing the hydraulic pressure at both ends of the cylinder 9. During this process, the hydraulic pressure at the upper and lower ends of the piston rod 17 is balanced until the hydraulic pressure value reaches a value that matches the thickness of the filter material. At this time, the controller 2 starts the second pressure pump 16 and adjusts the opening of the pressure valve according to the thickness of the filter material. The second pressure pump 16 draws the liquid at the lower end of the cylinder 9 into the connecting channel 15 and delivers it to the upper end of the cylinder 9 at a constant flow rate. This causes the piston rod 17 in the cylinder 9 to descend at a specific speed, and the punching die 18 on the piston rod 17 to descend at a specific speed until the punching die 18 cuts the filter material. This makes the thickness of the filter material correspond to the punching pressure and punching speed, which can adapt to the trimming of filter materials of various thicknesses, avoids the re-layering of the filter material, avoids the compaction of the filter material edges, avoids increasing the wind resistance in this area, and ensures the uniformity of air circulation in the air conditioning filter element.

[0051] During the above process, even if the punching pressure increases, the piston rod 17 will not move. The descent of the piston rod 17 is only controlled by the second pressure pump 16 and the opening of the pressure valve, so that the punching speed and punching pressure can be controlled separately, which can meet the punching requirements of various filter materials.

[0052] It should be further explained that the rise of the first slider 4 will cause the first turntable 20 to rise, shortening the distance between the first turntable 20 and the second turntable 22. This causes the telescopic rod 21 to retract to accommodate the adjustment of the first slider 4. At the same time, the tilt angle of the telescopic rod 21 decreases, while the telescopic rod 21 remains tangent to the first turntable 20 and the second turntable 22, allowing the first turntable 20 and the second turntable 22 to rotate adaptively until the fastening bolt 5 re-fixes the first slider 4, thus fixing the tilt angle of the telescopic rod 21 and the baffle 23. At this point, the second fixing fixture is activated. The motor 31 on the 29 causes the drive shaft 32 on the motor 31 to drive the insert 38 to rotate through the cavity 37. The insert 38 drives the multi-stage gear 33 with the largest diameter to rotate. The multi-stage gear 33 with the largest diameter drives the gear disk 34 to rotate. This causes the rotating shaft 35 on the gear disk 34 to drive the transmission belt 36 to rotate. The transmission belt 36 drives the take-up roller 30 to rotate. This causes the take-up roller 30 to take up the filter material waste. As the filter material waste continues to curl on the take-up roller 30, the effective radius of the take-up roller 30 increases, and the take-up roller 30 and the filter material waste... The material continuously compresses the baffle 23, which remains fixed. This causes the gathering roller 30 and the crossbar 27 to move along the first groove 25 under the action of the reaction force. This keeps the angle between the gathering roller 30 and the second pressure roller 7 of the filter material constant, keeps the area of ​​the filter material covering the second pressure roller 7 constant, and keeps the surface tension applied by the second pressure roller 7 to the filter material constant. At the same time, as the crossbar 27 moves along the first groove 25, the lead screw 43 on the crossbar 27 drives the transmission gear 41 to move synchronously. The rack 42, which meshes with the transmission gear 41, is fixed to the first groove 25, causing the transmission gear to move synchronously. While the moving gear 41 slides, it rotates. The rotation of the transmission gear 41, in turn, drives the lead screw 43 to rotate. The third slider 44 on the lead screw 43 is restricted from rotating by the second groove 46, causing it to translate under the rotation of the lead screw 43. This causes the connecting rod 45 on the third slider 44 to translate the pull rod 39, which in turn causes the insert 38 on the pull rod 39 to translate. This allows the insert 38 to engage with the smaller-radius multi-stage gear 33, ensuring that the transmission shaft 32 can only drive the smaller-radius multi-stage gear 33 to rotate. According to the linear velocity formula... It can be seen that when the transmission speed (angular velocity w) of the motor 31 is constant, the smaller the radius r, the smaller the linear velocity v. Therefore, the linear velocity of the toothed disk 34 driven by the multi-stage gear 33 decreases. Conversely, the effective radius of the toothed disk 34 corresponding to the smaller radius of the multi-stage gear 33 is larger. According to the angular velocity formula... As can be seen, a decrease in linear velocity leads to an increase in radius and a smaller angular velocity. Consequently, the rotational speeds of the gear disc 34, shaft 35, and drive belt 36 decrease, indirectly reducing the angular velocity of the take-up roller 30. In summary, the thicker the filter media waste material wound on the take-up roller 30, the smaller the angular velocity of the take-up roller 30. This balances the increase in linear velocity on the outermost side of the take-up roller 30, ensuring a constant linear velocity of the filter media driven by the take-up roller 30. This also ensures a constant surface tension applied to the filter media by the take-up roller 30. Therefore, during the filter media trimming process, its surface tension can be stabilized within a specific range, thus guaranteeing the punching effect of the filter media, further ensuring the quality of the filter media, and improving the punching efficiency to complete the operation.
