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 precision after punching, and also making it difficult for the punching die to cut off the filter material. If the tension is too large, the pulling force of the filter material is too large, which causes 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 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, which directly affects the punching effect of the filter material and also affects 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.

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

[0016] 2、The first slider is lifted by the filter material, the laser ranging sensor on the first slider is displaced, the laser ranging sensor automatically detects the thickness of the filter material, and the thickness value is transmitted to the controller, the first pressure pump is started according to the thickness value by the controller, then the first pressure pump draws external liquid through the conduit and delivers it into the distribution cavity, and the liquid is delivered to the two ends of the cylinder through the shunt, the hydraulic pressure of the two ends of the cylinder is increased, in this process, the hydraulic pressure of the upper and lower ends of the piston rod is balanced, until the hydraulic pressure value reaches a value matched with the thickness of the filter material, at this time, the second pressure pump is started by the controller, and the opening of the pressure valve is adjusted according to the thickness value of the filter material, so that the second pressure pump draws the liquid at the lower end of the cylinder into the communication channel and delivers it to the upper end of the cylinder at a constant flow, so that the piston rod in the cylinder descends at a certain speed, and the blanking die on the piston rod descends at a certain speed, until the blanking die cuts the filter material, so that the thickness of the filter material corresponds to the blanking pressure and the blanking speed, and the filter material of various thicknesses can be trimmed, the filter material is prevented from being re-layered, the compaction of the edge of the filter material is avoided, the wind resistance of the region is avoided, and the uniformity of air flow of the air conditioner filter core is ensured.

[0017] 3、The blanking pressure of the present application is increased, and the piston rod does not move, and the descent of the piston rod is only regulated by the second pressure pump and the opening of the pressure valve, so that the blanking speed and the blanking pressure can be controlled separately, and the blanking requirements of various filter materials can be met.

DETAILED DESCRIPTION

[0020] The specific embodiments of the present application will be further described below with reference to the drawings.

[0022] See Figure 2 and Figure 3The shunt channel 13 communicates with the distribution cavity 10, both ends of the shunt channel 13 and the communication channel 15 communicate with both ends of the cylinder body 9, the one-way valve 14 blocks the backflow of liquid in the cylinder body 9, the first pressure pump 11 and the second pressure pump 16 are electrically connected with the controller 2, and the output end of the second pressure pump 16 is provided with a pressure valve, and the opening of the pressure valve is controlled by the controller 2, and the blanking die 18 is slidably connected with the workbench 8.

[0023] Please refer to 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, and the top surface of the first sliding block 4 is provided with a laser ranging sensor, and the laser ranging sensor is electrically connected with the controller 2.

[0024] Specifically, in the process of blanking the filter material, the fastening bolt 5 on the rotary support 3 releases the fixation of the support 3 and the first sliding block 4, so that the first pressure roller 6 and the second pressure roller 7 on the first sliding block 4 can be lifted, and then the filter material on the stretching unwinding machine is stretched, so that the filter material passes through the first pressure roller 6 and the second pressure roller 7 in turn, and the fastening bolt 5 is rotated to fix the first pressure roller 6 and the second pressure roller 7 on the first sliding block 4 again, so that the filter material between the first pressure roller 6 and the second pressure roller 7 is flat, and finally the filter material is wound on the bunching roller 30, completing the preparation work. In the above process, when the filter material passes through the first pressure roller 6 and the second pressure roller 7, the first sliding block 4 is lifted, so that the laser ranging sensor on the first sliding block 4 is displaced, so that the laser ranging sensor automatically detects the thickness of the filter material, and transmits the thickness value to the controller 2, and the controller 2 starts the first pressure pump 11 according to the thickness value, so that the first pressure pump 11 draws external liquid through the conduit 12 and delivers it into the distribution cavity 10, and then the liquid is delivered into both ends of the cylinder body 9 through the shunt channel 13, increasing the hydraulic pressure at both ends of the cylinder body 9. In this process, the hydraulic pressure at both ends of the piston rod 17 is balanced until the hydraulic pressure value reaches a value matching 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 value of the filter material, so that the second pressure pump 16 draws the liquid at the lower end of the cylinder body 9 into the communication channel 15 and delivers it to the upper end of the cylinder body 9 at a constant flow rate, so that the piston rod 17 in the cylinder body 9 descends at a certain speed, so that the blanking die 18 on the piston rod 17 descends at a certain speed, until the blanking die 18 cuts the filter material, so that the thickness of the filter material corresponds to the blanking pressure and the blanking speed, which can adapt to filter materials of various thicknesses, avoid re-layering of the filter material, avoid compaction of the edges of the filter material, avoid increasing the wind resistance of the area, and ensure the uniformity of air flow through the air conditioner filter element.

[0025] The controller 2 in this embodiment adjusts the working parameters of the first pressure pump 11 and the second pressure pump 16 according to the filter thickness value detected by the laser ranging sensor through a preset control algorithm. The specific control logic is as follows: Thickness-pressure relationship: the punching pressure P and the filter thickness d satisfy a linear relationship , where k1 is the pressure coefficient (value range 0.5-1.5 MPa / mm), b1 is the reference pressure (value range 0.1-0.5 MPa), the controller calculates the target pressure P according to the thickness value d and controls the first pressure pump 11 to output the corresponding hydraulic pressure; Thickness-velocity relationship: the punching velocity v and the filter thickness d satisfy an inverse relationship , where k2 is the velocity coefficient (value range 10-50 mm 2 / s), the controller calculates the target velocity v according to the thickness value d and controls the flow rate by adjusting the pressure valve opening of the second pressure pump 16 to achieve a specific descending velocity of the piston rod 17; Control algorithm: the controller uses the PID (proportional-integral-derivative) algorithm to adjust the pressure valve opening in real time to ensure the stability of the punching velocity, where the PID parameters can be preset according to the filter material and thickness; The laser ranging sensor can be a laser displacement sensor (such as KEYENCE IL-100 series) with an accuracy of ±0.1 mm and a range of 0-10 mm to ensure accurate thickness detection; 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%; The filter is an activated carbon composite filter, including a non-woven fabric primary efficiency layer, an activated carbon adsorption layer, and a HEPA high-efficiency layer, with a total thickness range of 0.5-5 mm and a tensile strength not less than 20 N / cm. The punching die 18 is designed for this thickness range, and the punching pressure and velocity are adjusted according to the above relationship.

[0031] Please refer to Figures 6-8 The rotating shaft 35 is rotatably connected with the second fixed tool 29, the pull rod 39 is slidingly sleeved with the end of the transmission shaft 32, the effective diameter of the multi-stage gear 33 is gradually reduced, the effective diameter of the toothed disc 34 is gradually increased, the transmission gear 41 and the rack 42 are located in the fixed frame 24, the rack 42 is fixedly connected with the bottom surface of the first sliding groove 25, and the transmission gear 41 is slidingly connected with the first sliding groove 25.

[0032] Specifically, in the process of winding the filter material waste, the rising of the first slider 4 drives the first rotating disc 20 to rise, so that the distance between the first rotating disc 20 and the second rotating disc 22 is shortened, so that the telescopic rod 21 is retracted to adapt to the adjustment of the first slider 4, and at the same time, the inclination angle of the telescopic rod 21 is reduced, and the telescopic rod 21 is always tangent to the first rotating disc 20 and the second rotating disc 22, so that the first rotating disc 20 and the second rotating disc 22 adaptively rotate until the fastening bolt 5 re-fixes the first slider 4, so that the inclination angle of the telescopic rod 21 and the baffle 23 is fixed, and then the motor 31 on the second fixed tooling 29 is started again, so that the transmission shaft 32 on the motor 31 drives the embedded block 38 to rotate through the embedded cavity 37, so that the embedded block 38 drives the multi-stage gear 33 with the maximum diameter to rotate, so that the multi-stage gear 33 with the maximum diameter drives the toothed disc 34 to rotate, so that the rotating shaft 35 on the toothed disc 34 drives the transmission belt 36 to rotate, so that the transmission belt 36 drives the bunching roller 30 to rotate, and then the bunching roller 30 winds the filter material waste, and as the filter material waste continues to be wound on the bunching roller 30, the effective radius of the bunching roller 30 increases, so that the bunching roller 30 and the filter material continuously press the baffle 23, and the baffle 23 is fixed, so that the bunching roller 30 and the cross rod 27 move along the first sliding groove 25 under the action of the reaction force, so that the inclination angle of the filter material between the bunching roller 30 and the second compression roller 7 is constant, so that the area of the filter material covering the second compression roller 7 is constant, so that the surface tension of the second compression roller 7 on the filter material is constant, and at the same time, as the cross rod 27 moves along the first sliding groove 25, the lead screw 43 on the cross rod 27 drives the transmission gear 41 to move synchronously, and the rack 42 connected with the transmission gear 41 is fixedly connected with the first sliding groove 25, so that the transmission gear 41 rotates while sliding, and the rotation of the transmission gear 41 drives the lead screw 43 to rotate, and the third slider 44 on the lead screw 43 is limited from rotating by the second sliding groove 46, so that the third slider 44 translates under the rotation of the lead screw 43, so that the connecting rod 45 on the third slider 44 drives the pull rod 39 to translate, so that the embedded block 38 on the pull rod 39 translates, and then the embedded block 38 is connected with the multi-stage gear 33 with a smaller radius, so that the transmission of the transmission shaft 32 can only drive the multi-stage gear 33 with a smaller radius to rotate, according to the linear velocity formula , it can be known that when the transmission speed, i.e., the angular velocity w of the motor 31 is constant, the smaller the radius r is, the smaller the linear velocity v is, so the linear velocity of the toothed disc 34 driven by the multi-stage gear 33 is reduced, and the effective radius of the toothed disc 34 corresponding to the multi-stage gear 33 with a smaller radius is larger, according to the angular velocity formula It can be seen that the linear speed decreases, the radius increases, and the angular speed is smaller, so the rotating speed of the toothed disc 34, the rotating shaft 35 and the transmission belt 36 decreases, which indirectly reduces the angular speed of the bunching roller 30. In summary, the thicker the filter material waste wound on the bunching roller 30, the smaller the angular speed of the bunching roller 30, so that the increase of the linear speed of the outermost side of the bunching roller 30 is balanced, the linear speed of the filter material driven by the bunching roller 30 is constant, the surface tension of the filter material exerted by the bunching roller 30 is constant, and thus the surface tension of the filter material during trimming can be stabilized in a specific range, thereby ensuring the blanking effect of the filter material, further ensuring the use quality of the filter material, and improving the blanking efficiency.

[0033] In the embodiment, the multi-stage gear 33 can adopt a three-stage gear set, the transmission ratios are i1=3:1, i2=2:1 and i3=1.5:1 in sequence, the gear modulus is 1.5 mm, and the switching trigger condition is that the radius of the bunching roller 30 increases by 5 mm, the block 38 translates by one level, and the radius of the multi-stage gear 33 decreases correspondingly. The telescopic rod 21 can be an electric telescopic rod, and the stroke is 0-50 mm, and the response time is less than 0.1 s.

[0034] The working principle and use process of the present application: when the filter material needs to be punched, the fastening bolt 5 on the rotating support 3 is pulled, so that the support 3 is released from the fixing of the first sliding block 4, so that the first pressure roller 6 and the second pressure roller 7 on the first sliding block 4 can be lifted, and then the filter material on the stretching unwinding machine is stretched, so that the filter material passes through the first pressure roller 6 and the second pressure roller 7 in turn, and the fastening bolt 5 is turned to fix the first pressure roller 6 and the second pressure roller 7 on the first sliding block 4 again, so that the filter material between the first pressure roller 6 and the second pressure roller 7 is flat, and finally the filter material is wound on the collecting roller 30, completing the preparation work. In the above process, the filter material passes through the first pressure roller 6 and the second pressure roller 7, which will make the first sliding block 4 lift, so that the laser ranging sensor on the first sliding block 4 will produce displacement, so that the laser ranging sensor can automatically detect the thickness of the filter material, and the thickness value will be transmitted to the controller 2, and the controller 2 will start the first pressure pump 11 according to the thickness value, so that the first pressure pump 11 will draw the liquid outside through the conduit 12 and deliver it to the distribution chamber 10, and then the liquid will be delivered to both ends of the cylinder 9 through the shunt 13, so as to increase the hydraulic pressure at both ends of the cylinder 9. In this process, the hydraulic pressure at both ends of the piston rod 17 is balanced, until the hydraulic pressure value reaches a value matching the thickness of the filter material. At this time, the controller 2 will start the second pressure pump 16, and adjust the opening of the pressure valve according to the thickness value of the filter material, so that the second pressure pump 16 will draw the liquid at the lower end of the cylinder 9 into the communication channel 15, and deliver it to the upper end of the cylinder 9 at a constant flow rate, so that the piston rod 17 in the cylinder 9 will descend at a certain speed, so that the punching die 18 on the piston rod 17 will descend at a certain speed, until the punching die 18 cuts the filter material, so that the thickness of the filter material corresponds to the punching pressure and the punching speed, which can adapt to the trimming of filter materials of various thicknesses, avoid the re-layering of the filter material, and also avoid the compaction of the edges of the filter material, avoid increasing the wind resistance of the area, and ensure the uniformity of the air flow through the air conditioner filter element; In the above process, even if the punching pressure increases, the piston rod 17 will not move, and 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 the punching pressure can be controlled separately, which can meet the punching needs of various filter materials; It needs to be further explained that the rising of the first slider 4 will drive the first rotating disc 20 to rise, so that the distance between the first rotating disc 20 and the second rotating disc 22 is shortened, so that the telescopic rod 21 is retracted to adapt to the adjustment of the first slider 4, at the same time, the inclination angle of the telescopic rod 21 is reduced, and the telescopic rod 21 is always tangent to the first rotating disc 20 and the second rotating disc 22, so that the first rotating disc 20 and the second rotating disc 22 adaptively rotate until the fastening bolt 5 re-fixes the first slider 4, so that the inclination angle of the telescopic rod 21 and the baffle 23 is fixed, at this time, the motor 31 on the second fixed tooling 29 is started again, so that the transmission shaft 32 on the motor 31 drives the embedded block 38 to rotate through the embedded cavity 37, so that the embedded block 38 drives the multi-stage gear 33 with the maximum diameter to rotate, so that the multi-stage gear 33 with the maximum diameter drives the toothed disc 34 to rotate, so that the rotating shaft 35 on the toothed disc 34 drives the transmission belt 36 to rotate, so that the transmission belt 36 drives the bunching roller 30 to rotate, and then the bunching roller 30 winds the filter material waste, with the continuous curling of the filter material waste on the bunching roller 30, the effective radius of the bunching roller 30 increases, so that the bunching roller 30 and the filter material continuously press the baffle 23, and the baffle 23 is fixed, so that the bunching roller 30 and the cross rod 27 move along the first sliding groove 25 under the action of the reaction force, so that the inclination angle of the filter material between the bunching roller 30 and the second compression roller 7 is constant, so that the area of the filter material covering the second compression roller 7 is constant, so that the surface tension of the second compression roller 7 on the filter material is constant, at the same time, with the movement of the cross rod 27 along the first sliding groove 25, the lead screw 43 on the cross rod 27 drives the transmission gear 41 to move synchronously, and the rack 42 connected with the transmission gear 41 is fixedly connected with the first sliding groove 25, so that the transmission gear 41 rotates while sliding, and the rotation of the transmission gear 41 drives the lead screw 43 to rotate, the third slider 44 on the lead screw 43 cannot rotate due to the limitation of the second sliding groove 46, so that the third slider 44 translates under the rotation of the lead screw 43, so that the connecting rod 45 on the third slider 44 drives the pull rod 39 to translate, so that the embedded block 38 on the pull rod 39 translates, and then the embedded block 38 is connected with the multi-stage gear 33 with smaller radius, so that the transmission of the transmission shaft 32 can only drive the multi-stage gear 33 with smaller radius to rotate, according to the linear velocity formula , it can be known that when the transmission speed, i.e. the angular velocity w of the motor 31 is constant, the smaller the radius r is, the smaller the linear velocity v is, so the linear velocity of the toothed disc 34 driven by the multi-stage gear 33 is reduced, and the effective radius of the toothed disc 34 corresponding to the multi-stage gear 33 with smaller radius is larger, according to the angular velocity formula It can be seen that the linear speed is reduced, the radius is increased, and the angular speed is smaller, so the rotating speed of the toothed disc 34, the rotating shaft 35 and the transmission belt 36 is reduced, which indirectly reduces the angular speed of the bunching roller 30. In summary, the thicker the filter material waste wound on the bunching roller 30, the smaller the angular speed of the bunching roller 30, so that the increase of the linear speed of the outermost side of the bunching roller 30 is balanced, the linear speed of the filter material driven by the bunching roller 30 is constant, the surface tension of the filter material exerted by the bunching roller 30 is constant, so that the surface tension of the filter material during trimming can be stabilized in a specific range, thereby ensuring the blanking effect of the filter material, further ensuring the use quality of the filter material, and improving the blanking efficiency and completing the operation.
