Description

Technical Field

[0001] This invention relates to the field of meltblown filter manufacturing technology, specifically to a continuous receiving device for meltblown filter elements. Background Technology

[0002] Meltblown filter cartridges (especially those made of PP material) have become one of the most widely used filter cartridge types in industrial and civil filtration fields due to their excellent cost performance, good deep filtration performance, high dirt holding capacity and wide applicability. During the production process of meltblown filter cartridges, in order to facilitate the subsequent manufacturing of filter cartridges, a receiving device is needed to receive and wind up the fiber web formed by meltblowing in the production equipment.

[0003] However, existing receiving devices typically require downtime for roll changing during the receiving process of meltblown fiber webs, resulting in intermittent receiving efficiency, high labor costs, potential impact on product consistency, material waste, and reduced filter element production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous receiving device for meltblown filter cartridges. Through the structural design of the V-shaped frame, the winding and fixing assembly and the second motor, this receiving device can ensure continuous and uninterrupted receiving of meltblown fiber web, thus solving the problem of intermittent receiving of meltblown fiber web.

[0005] This invention is achieved through the following technical solution:

[0006] This invention relates to a continuous receiving device for meltblown filter cartridges, comprising meltblown filter cartridge manufacturing equipment and a V-shaped frame. The bottom of the meltblown filter cartridge manufacturing equipment is provided with a base plate, and a transmission belt is provided on the base plate. The V-shaped frame is set on the base plate, and a rotating rod is rotatably mounted on the V-shaped frame. Five winding and fixing components are provided on the outer surface of the rotating rod. The winding and fixing components include a U-shaped bracket, and two T-shaped columns are rotatably mounted on the U-shaped bracket. One end of each T-shaped column has three through holes, and a crossbar is slidably fitted in each of the three through holes. A spring is fitted with the outer surface of the crossbar with clearance. An external support component is provided at one end of each of the three crossbars.

[0007] Furthermore, two circular grooves are provided on the V-shaped frame, and bearings are fitted into the grooves. The outer surfaces of both ends of the rotating rod are respectively fitted with the inner rings of the two bearings.

[0008] Furthermore, one end of the rotating rod passes through the circular groove to the outside of the V-shaped frame, and a second motor is installed on the V-shaped frame. The output end of the second motor is connected to one end of the rotating rod. The second motor is a permanent magnet stepper motor.

[0009] Furthermore, two circular grooves are provided on the U-shaped bracket, and a bearing is fitted inside the circular groove. The surface of the T-shaped column away from the through hole fits with the inner ring of the bearing.

[0010] Furthermore, one end of one of the T-shaped columns away from the through hole passes through the second circular groove to the outside of the U-shaped bracket. A motor is installed on the U-shaped bracket, and the output end of the motor is connected to the end of one of the T-shaped columns away from the through hole.

[0011] Furthermore, the external support assembly includes an assembly plate with three receiving slots. A fixing rod is installed in each receiving slot. A spring is fitted on the outer surface of the fixing rod. A movable sleeve is fitted on the outer surface of one end of the fixing rod. The movable sleeve engages with the receiving slot. An arc-shaped support plate is provided on one side of the movable sleeve.

[0012] Furthermore, the outer surface of the arc-shaped support plate is uniformly provided with anti-slip protrusions, which are irregular elastic rubber protrusions.

[0013] Furthermore, the meltblown filter element manufacturing equipment is equipped with a die head, one end of the transmission belt is located directly below the die head, and the V-shaped frame is located at the end of the transmission belt away from the die head and on the horizontal center line of the transmission belt.

[0014] Furthermore, a condensing mesh curtain is provided on the surface of the transmission belt, and an electrostatic eliminator is provided on the transmission belt, with the electrostatic eliminator located directly above the condensing mesh curtain.

[0015] Furthermore, a guide roller one is provided at the end of the transmission belt away from the die head, and a guide roller two is horizontally provided on the side of the bottom of the guide roller one.

[0016] The present invention has the following beneficial effects:

[0017] 1. This invention, through the structural design of a V-shaped frame, winding and fixing components, and a second motor, uses the energization and de-energization of the second motor to cause the five winding and fixing components on the rotating rod to rotate and lock on the V-shaped frame. This allows the five winding and fixing components to wind up the fiber web one by one, thereby ensuring that the receiving device can continuously and uninterruptedly receive meltblown fiber web, effectively improving the receiving efficiency of meltblown fiber web, greatly reducing labor costs, ensuring product consistency, reducing material waste, and improving the production efficiency of filter elements.

[0018] 2. Through the structural design of the winding fixing component and the external support component, the inner rings at both ends of the core are fixed to the corresponding two external support components by the contraction and rebound of six springs. This achieves the fixing of paper tube cores of different widths, thereby enabling the winding and receiving of meltblown fiber webs of different widths. The operation is simple, the applicability is strong, the application range of the device is enriched, and the winding effect of the device is improved.

[0019] 3. Through the structural design of the external support assembly, the present invention utilizes the rebound force generated by the contraction of three springs and the anti-slip protrusions evenly distributed on the surface of the three arc-shaped support plates to ensure that the inner rings at both ends of the paper tube core are tightly fitted with the outer surfaces of the corresponding three arc-shaped support plates. This allows for convenient expansion and fixation of the inner rings at both ends of the paper tube core, preventing the paper tube core from rotating relative to the T-shaped column or wobbling during the winding of the fiber web, thus improving the stability of the device for winding the fiber web.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Please see Figure 1-5This invention provides a technical solution: a continuous receiving device for meltblown filter elements, including a meltblown filter element manufacturing equipment 1 and a V-shaped frame 3. A base plate is provided at the bottom of the meltblown filter element manufacturing equipment 1, and a transmission belt 2 is provided on the base plate. A die head is provided on the meltblown filter element manufacturing equipment 1. One end of the transmission belt 2 is located directly below the die head. The V-shaped frame 3 is located at the end of the transmission belt 2 away from the die head and on the horizontal center line of the transmission belt 2, which facilitates the continuous ejection and reception of meltblown fiber web. A condensing screen is provided on the surface of the transmission belt 2, which can collect the ultrafine fibers ejected from the die head, ensuring that the ultrafine fibers can be randomly stacked, wound, and bonded together. A self-adhesive, non-woven fiber web is formed on the surface of the condensing screen. An electrostatic eliminator is installed on the transmission belt 2, located directly above the condensing screen. The electrostatic eliminator effectively eliminates the high static charge carried by the meltblown fiber web before winding, preventing tangling, wrinkling, dust adsorption, or operational hazards. A guide roller 7 is installed at the end of the transmission belt 2 away from the die head. A guide roller 8 is horizontally installed on the side of the bottom of the guide roller 7. Both the guide roller 7 and the guide roller 8 are rotatably mounted on a bracket. The surfaces of the guide roller 7 and the guide roller 8 are covered with a smooth Teflon layer, which can prevent adhesion or damage to the fiber web and can pull the meltblown fiber web to ensure smooth winding.

[0029] V-shaped frame 3 is mounted on the base plate. A rotating rod 301 is rotatably mounted on V-shaped frame 3. Two circular slots are opened on V-shaped frame 3, and bearings are fitted in the circular slots. The outer surfaces of both ends of rotating rod 301 are respectively engaged with the inner rings of the two bearings to ensure the rotation effect of rotating rod 301 on V-shaped frame 3. One end of rotating rod 301 passes through the circular slots to the outside of V-shaped frame 3. Motor 6 is mounted on V-shaped frame 3. The output end of motor 6 is connected to one end of rotating rod 301 to provide driving force for the rotation of rotating rod 301. Motor 6 is a permanent magnet stepper motor. The output end can be self-locked after motor 6 is de-energized to ensure the accuracy of the rotation position of the five winding fixing components 4 on rotating rod 301, which facilitates the continuous winding of meltblown fiber web. Five winding fixing components 4 are provided on the outer surface of rotating rod 301.

[0030] In use, five paper roll cores are taken out and fixed onto the five winding fixing components 4 on the outer surface of the rotating rod 301. Then, the meltblown filter element manufacturing equipment 1 and the transmission belt 2 are started, so that the die head on the meltblown filter element manufacturing equipment 1 blows the ultrafine fibers onto the surface of the condensing screen on the transmission belt 2 to form a meltblown fiber web. The meltblown fiber web on the condensing screen is conveyed by the transmission belt 2 to one end near the guide roller 7. Then, one end of the meltblown fiber web is pulled out so that one end of the meltblown fiber web passes through the guide roller 7 and the guide roller 8, guiding the meltblown fiber web smoothly into the vicinity of the V-shaped frame 3. Then, the motor 6 is started, so that the rotating rod 301 rotates on the V-shaped frame 3. Through the rotation of the rotating rod 301, the empty roll core fixed on one of the winding fixing components 4 is rotated to the winding area of ​​the meltblown fiber web. Then, the motor 6 is disconnected. The end of the meltblown fiber web is wound around the surface of the corresponding paper roll core. Then, the motor 405 on one of the winding fixing components 4 is started, so that the output end of the motor 405 drives the paper roll core fixed between the two external support components 5 to rotate at a constant speed. When enough meltblown fiber web is wound on the paper roll core, the operator quickly cuts the fiber web and controls the motor 6 to rotate, and rotates the winding fixing component 4 with the empty paper roll core to the winding area. Then, the end of the fiber web is rewound around the surface of the empty roll core, and the motor 405 on the corresponding winding fixing component 4 is started to wind the fiber web. During the winding of the fiber web on the new empty roll core, the full roll on the corresponding winding fixing component 4 is unloaded. By repeating the above operation, the uninterrupted continuous reception of meltblown fiber web can be achieved.

[0031] The winding fixing assembly 4 includes a U-shaped bracket 401, on which two T-shaped posts 402 are rotatably mounted. Two circular grooves are formed on the U-shaped bracket 401, and bearings are fitted into the grooves. The surface of the T-shaped post 402 furthest from the through hole 4021 mates with the inner ring of the bearing, ensuring the rotation of the T-shaped post 402 on the U-shaped bracket 401. One end of the T-shaped post 402 furthest from the through hole 4021 passes through the circular groove to the outside of the U-shaped bracket 401. A motor 405 is installed on the bracket 401. The output end of the motor 405 is connected to the end of one of the T-shaped columns 402 away from the through hole 4021. It can provide power for the rotation of the paper roll core between the two T-shaped columns 402. One end of the T-shaped column 402 has three through holes 4021. A crossbar 403 is slidably fitted in each of the three through holes 4021. A spring 404 is fitted with the outer surface of the crossbar 403. An external support assembly 5 is installed at one end of the three crossbars 403.

[0032] When receiving fiber webs of different widths, take out the paper tube core of the corresponding width, fit the inner ring of one end of the core onto an outer support component 5 on the winding fixing component 4, and then push the paper tube core to squeeze the corresponding outer support component 5. After the outer support component 5 is subjected to outward squeezing force, it causes the three crossbars 403 to slide in the three corresponding through holes 4021 on the T-shaped column 402. Through the horizontal movement of the three crossbars 403 on the T-shaped column 402, the springs 404 on the outer surface of the crossbars 403 are compressed and contracted, causing the paper tube core to move towards one side of the U-shaped bracket 401 until the other end of the paper tube core is aligned with another outer support component 5. Then, slowly release the pushing force on the paper tube core. Under the action of the contraction and rebound of the six springs 404, the inner rings at both ends of the core are fixed on the corresponding two outer support components 5, thereby fixing paper tube cores of different widths and realizing the winding of meltblown fiber webs of different widths.

[0033] The outer support assembly 5 includes an assembly plate 501, on which three receiving slots 5011 are provided. A fixing rod 502 is provided in the receiving slot 5011. A spring 504 is fitted on the outer surface of the fixing rod 502. A movable sleeve 503 is fitted on the outer surface of one end of the fixing rod 502. The movable sleeve 503 cooperates with the receiving slot 5011. An arc-shaped support plate 505 is provided on one side of the movable sleeve 503. Anti-slip protrusions are evenly distributed on the outer surface of the arc-shaped support plate 505. The anti-slip protrusions are irregular elastic rubber protrusions, which can improve the fixing and locking effect on the inner ring of the paper tube core and prevent relative rotation between the paper tube core and the two outer support assemblies 5.

[0034] During the process of fixing the paper tube core, the inner ring of one end of the paper tube core is fitted onto the outer surface of three arc-shaped support plates 505 on one of the outer support components 5. By pushing the paper tube core, the inner ring of the core is pressed against the three arc-shaped support plates 505, causing the three arc-shaped support plates 505 to generate a pressing force towards the center of the assembly plate 501. After being subjected to the pressing force, the arc-shaped support plates 505 push the movable sleeve 503, which is fixedly connected at one end, to slide on the surface of the fixed rod 502 in the corresponding receiving groove 5011, so that the movable sleeve 503 compresses the spring 504. When spring 2 504 is compressed, it contracts. Since the inner ring of the paper tube core is circular, the three arc-shaped support plates 505 move inward simultaneously, allowing them to enter the inner ring of the paper tube core. Then, the core is pushed to one side, fixing the other end of the core to the outer surface of the corresponding three arc-shaped support plates 505. Through the rebound force generated by the contraction of the three springs 2 504 and the anti-slip protrusions evenly distributed on the surface of the three arc-shaped support plates 505, the inner rings at both ends of the paper tube core are tightly fitted to the outer surface of the corresponding three arc-shaped support plates 505.
