Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-woven bag production, and particularly relates to a dust suction device for non-woven bag production. BACKGROUND

[0002] A large amount of mixed dust containing long fibers is generated in the production process of non-woven bags. Such dust is easy to entangle and accumulate, and needs to be timely treated by a dust suction device to ensure the production environment and product quality. In the prior art, the dust suction device for non-woven bag production generally adopts a staged filtration design, usually including a first-stage filtration bin and a second-stage filtration bin. A metal filter screen is arranged in the first-stage filtration bin for intercepting large-particle fiber dust, and a precision filter element is arranged in the second-stage filtration bin for intercepting small dust. The device provides negative pressure suction by a fan, and the dust at the production site is sucked into the suction bin and sequentially passes through the first-stage and second-stage filtration bins for purification. The purified gas is discharged through a discharge pipeline. The first-stage and second-stage filtration bins are usually fixedly installed in the device shell by means of bolts or clamping, and the filtration components and the conveying pipeline form a fixed communication structure.

[0003] In the prior art, after the filtration components are used for a period of time, a large amount of fiber dust is attached to the surface of the filtration components, resulting in a decrease in filtration efficiency and a decrease in air intake. Therefore, the filter screen or filter element in the filtration bin must be cleaned or replaced regularly. However, since the filtration bin is fixedly connected with the device shell and the conveying pipeline, the filtration components can be removed only after the fan is turned off, the suction power is cut off, and the relevant connecting components are disassembled. This process inevitably causes the non-woven bag production process to be forced to stop. For a continuous non-woven bag production line, frequent stoppage of operation will disrupt the production rhythm, not only reducing the product output per unit time, but also possibly causing semi-finished products to accumulate and the quality consistency of batch products to be affected, and seriously restricting the improvement of overall production efficiency. SUMMARY

[0004] The present application aims to at least solve one of the problems in the related art to some extent.

[0005] To this end, the present application aims to provide a dust suction device for non-woven bag production, which adopts a staged design of preliminary filtration by a first-stage filtration bin and fine filtration by a second-stage filtration switching mechanism. The device comprises a plurality of second-stage filtration bins arranged at equal intervals and a conveying head vertically displaceable. The driving device drives the driving arm and the conveying head to vertically move along the guide frame. The precise sealing butt joint of the conveying head and the target second-stage filtration bin is realized by the adsorption cooperation of the magnetic suction head and the adsorption head. This scheme can switch the standby second-stage filtration bin without stopping the machine, and simultaneously clean or replace the filtration bin, thereby completely solving the problem of production interruption caused by the need to stop the machine for maintenance of the filtration components in the prior art.

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] The dust collection device for non-woven bag production according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0020] like Figures 1-6 As shown, the dust collection device for non-woven bag production according to an embodiment of the present invention may include a support platform 1, a support frame 2, a dust collection chamber 3, a support plate 4, a primary filter chamber 5, a first fan 6, a conveying pipe 7, a fixing frame 8, and a secondary filter switching mechanism 9.

[0021] The support frame 2 is fixedly connected to the top end of the support platform 1, the dust collection chamber 3 is fixedly connected to the top of the support platform 1 and the support frame 2, the support plate 4 is fixedly connected to the inner wall of the dust collection chamber 3, the primary filter chamber 5 is snapped into the inner wall of the support plate 4, the first fan 6 is installed on the top of the support frame 2, and a conveying pipe 7 is provided between the primary filter chamber 5 and the output end of the first fan 6, and they are connected through the conveying pipe 7.

[0022] It should be noted that the support platform 1 and support frame 2 described in this embodiment form a double support structure, which not only provides a stable installation foundation for the dust collection chamber 3, but also reserves reasonable installation space for the first fan 6 through the height design of the support frame 2, avoiding the vibration generated by the fan during operation from being directly transmitted to the dust collection chamber 3 and affecting the filtration effect. The support plate 4 plays a role in precise positioning and stable support for the primary filter chamber 5. The snap-fit ​​connection design makes it possible to disassemble and install the primary filter chamber 5 without additional tools, which is convenient for later maintenance and cleaning. The conveying pipe 7 realizes the sealed connection between the primary filter chamber 5 and the first fan 6, ensuring that the negative pressure suction generated by the fan can be effectively applied to the dust collection chamber 3, while preventing dust leakage during the conveying process, thus ensuring the sealing performance of the dust collection device and the cleanliness of the working environment.

[0023] The mounting bracket 8 is fixedly connected to the inner wall of the dust collection chamber 3, and the secondary filter switching mechanism 9 is installed on the mounting bracket 8.

[0024] It should be noted that the fixing frame 8 described in this embodiment adopts a fixing method that fits against the inner wall of the dust collection chamber 3. This not only improves the firmness of its own installation, but also provides a stable support benchmark for the secondary filter switching mechanism 9, preventing the switching mechanism from shifting or shaking during operation. Integrating the secondary filter switching mechanism 9 onto the fixing frame 8 allows the various components of the switching mechanism to form a compact overall structure, reducing the space occupied in the dust collection chamber 3. At the same time, it facilitates the coordinated action between the components, ensuring the accuracy of the docking between the conveyor head 93 and the secondary filter chamber 91. This provides structural protection for the realization of the non-stop switching function and further improves the stability and reliability of the device operation.

[0025] Specifically, after external power is supplied, the first fan 6 starts and forms a negative pressure suction in the dust collection chamber 3 through the conveying pipe 7. The dust generated during the production of non-woven bags is sucked into the dust collection chamber 3 and first undergoes preliminary filtration through the primary filter chamber 5, which is snapped onto the support plate 4, to intercept large particles of fiber dust. The dust after preliminary filtration is conveyed through the conveying assembly 96 to the conveying head 93 of the secondary filtration switching mechanism 9. The controller 954 controls the drive device 941 to operate, driving the drive arm 942 and the conveying head 93 to move vertically along the guide frame 92. Through the adsorption cooperation between the magnetic head 951 and the adsorption head 953, the conveying head 93 and the target secondary filter chamber 91 on the fixed frame 8 are precisely sealed and connected. The dust enters the secondary filter chamber 91 for fine filtration. After filtration, the purified gas is discharged through the connecting pipe 10 and the discharge pipe 12. When the currently used secondary filter chamber 91 needs to be cleaned or replaced due to dust accumulation, the controller 954 controls the magnetic suction head 951 to be de-energized, and the drive device 941 drives the conveyor head 93 to quickly switch to the backup secondary filter chamber 91 and complete the docking, ensuring that the filtration operation continues. At the same time, the operator can directly disassemble the replaced secondary filter chamber 91 for cleaning or replace the filter inner plate 912. The entire maintenance process does not require shutting down the first fan 6 or interrupting the dust collection operation. Through the design of "alternating use of multiple secondary filter chambers 91 + switching without shutdown", the problem of interruption of the non-woven bag production process and reduction of production efficiency caused by the need to stop the machine for maintenance of filter components in the background technology is completely solved.

[0026] In one embodiment of the present invention, such as Figures 1-6 As shown, the secondary filtration switching mechanism 9 includes a secondary filtration chamber 91, a guide frame 92, a conveying head 93, a drive assembly 94, an adsorption assembly 95, and a conveying assembly 96. Multiple secondary filtration chambers 91 are installed at equal intervals on a fixed frame 8. The guide frame 92 is symmetrically fixed to one side of the fixed frame 8. The conveying head 93 is slidably engaged with the inner wall of the guide frame 92 via the adsorption assembly 95. The drive assembly 94 is installed on the top of the dust collection chamber 3, and its output end is connected to the conveying head 93. The conveying assembly 96 is installed on the top of the dust collection chamber 3, and the primary filtration chamber 5 is connected to the conveying head 93 via the conveying assembly 96.

[0027] It should be noted that the secondary filtration switching mechanism 9 described in this embodiment, through the integrated design of the secondary filtration chamber 91, guide frame 92, conveyor head 93, drive assembly 94, adsorption assembly 95, and conveying assembly 96, forms a complete non-stop filtration switching system. Multiple secondary filtration chambers 91 are installed at equal intervals on the fixed frame 8, ensuring the regularity of the switching path of the conveyor head 93 and providing a structural foundation for rapid and accurate switching. The guide frame 92 is symmetrically fixed on one side of the fixed frame 8, providing bidirectional limiting for the sliding of the conveyor head 93, preventing lateral deviation during its movement, and ensuring the smooth operation of the conveyor head 93. The coaxiality of the secondary filter chamber 91 during docking, and the cooperation between the adsorption component 95 and the guide frame 92, not only enable the sliding engagement of the conveyor head 93, but also improve the sealing performance after docking to prevent dust leakage from the docking gap. The drive component 94 is installed on the top of the dust collection chamber 3 to provide stable power to the conveyor head 93, ensuring smooth and controllable switching action. The conveying component 96 establishes a dust conveying channel between the primary filter chamber 5 and the conveyor head 93, ensuring the continuity of dust transmission from primary filtration to secondary filtration. The synergistic effect of all components makes the secondary filter switching mechanism 9 have operational stability, docking accuracy, and high efficiency.

[0028] Specifically, when the secondary filtration switching mechanism 9 is working, the conveying component 96 continuously conveys the dust that has been preliminarily filtered by the primary filtration chamber 5 to the conveying head 93. After the drive component 94 starts, it drives the conveying head 93 to slide along the guide frame 92. When the conveying head 93 moves to the target secondary filtration chamber 91, the adsorption component 95 activates to achieve precise sealing and docking between the two. The dust then enters the secondary filtration chamber 91 for fine filtration. When the secondary filtration chamber 91 needs maintenance due to dust accumulation, the drive component 94 drives the conveying head 93 to detach from the chamber and quickly move to the backup secondary filtration chamber 91. The adsorption component 95 completes docking again, ensuring that the secondary filtration operation is not interrupted. Through the alternating use and smooth switching of multiple secondary filtration chambers 91, the problem of nonwoven bag production interruption caused by the need to stop the machine for maintenance of filter components in the background technology is effectively solved.

[0029] In one embodiment of the present invention, such as Figures 1-6 As shown, the drive assembly 94 includes a drive device 941 and a drive arm 942. The drive device 941 is installed on the top of the dust collection chamber 3. The output end of the drive device 941 passes through the top of the dust collection chamber 3 and is fixedly connected to one end of the drive arm 942. The other end of the drive arm 942 is fixedly connected to the outer wall of the conveying head 93.

[0030] It should be noted that the drive assembly 94 described in this embodiment adopts a simple transmission structure of "drive device 941 + drive arm 942". The drive device 941 is installed on the top of the dust collection chamber 3, which facilitates the later inspection and maintenance of the drive device 941 and avoids direct contact between it and the fiber dust in the dust collection chamber 3, reducing the wear of dust on the internal components of the drive device 941 and extending the service life of the drive assembly 94. The drive arm 942 serves as the power transmission carrier, with one end fixedly connected to the output end of the drive device 941 and the other end fixedly connected to the outer wall of the conveying head 93. This double fixed connection method can ensure the stability of power transmission, avoid power loss or transmission deviation, and ensure that the conveying head 93 obtains a stable and precise driving force. A sealing element can be added at the position where the output end of the drive device 941 penetrates the top of the dust collection chamber 3 to ensure the overall airtightness of the dust collection chamber 3 and prevent dust from leaking out from the penetration gap and polluting the working environment.

[0031] Specifically, when the drive assembly 94 is working, the controller 954 controls the drive device 941 to start. The drive device 941 outputs power to drive the drive arm 942 to make vertical displacement. The drive arm 942 then drives the conveyor head 93 to move vertically along the guide frame 92 synchronously, realizing the position switching of the conveyor head 93 between different secondary filter chambers 91. This design ensures that the switching action of the conveyor head 93 is precise and efficient through stable power transmission, so that the conveyor head 93 can quickly dock with the target secondary filter chamber 91, ensuring the continuity of secondary filtration operations. When a secondary filter chamber 91 needs maintenance, the drive assembly 94 can quickly drive the conveyor head 93 to switch to the standby chamber, and maintenance preparation can be completed without stopping the machine, effectively solving the pain point of needing to stop the machine for filter maintenance in the background technology.

[0032] In one embodiment of the present invention, such as Figures 1-6 As shown, the adsorption assembly 95 includes a magnetic suction head 951, a guide head 952, an adsorption head 953, and a controller 954. The magnetic suction head 951 is symmetrically embedded in one side of the fixing frame 8 and located on both sides of one end of the secondary filter chamber 91. The guide head 952 is symmetrically fixedly connected to the outer wall of the conveying head 93, and the end of the guide head 952 is slidably engaged with the inner wall of the guide frame 92. The adsorption head 953 is fixedly connected to the guide head 952. The controller 954 is installed on the top of the support platform 1.

[0033] It should be noted that the adsorption component 95 described in this embodiment achieves precise positioning through the magnetic attraction between the magnetic head 951 and the adsorption head 953. The magnetic head 951 is symmetrically embedded on one side of the fixing frame 8 and is set corresponding to the secondary filter chamber 91, which can ensure the positioning accuracy when the conveying head 93 is docked, and avoid dust leakage caused by docking deviation. The sliding snap-fit ​​structure between the guide head 952 and the guide frame 92 further improves the stability and guidance of the movement of the conveying head 93, forming a double guarantee with the magnetic positioning, preventing jamming or deviation during the movement of the conveying head 93. The adsorption head 953 is fixed on the guide head 952, which allows the adsorption force generated by the magnetic head 951 to act evenly on the conveying head 93, ensuring the sealing effect after docking and reducing the risk of dust leakage. The controller 954 is installed on the top of the support platform 1 to realize centralized control of the power supply to and from the magnetic head 951, so that the adsorption action is completed automatically without manual intervention, improving the intelligence and ease of operation of the device.

[0034] Specifically, when the adsorption component 95 is working, the controller 954, according to the action command of the drive component 94, controls the corresponding magnetic head 951 to be energized to generate magnetic force when the conveyor head 93 moves to the target secondary filter chamber 91 position. This magnetic force attracts the magnetic head 953 on the guide head 952 on the conveyor head 93, achieving a precise and sealed connection between the conveyor head 93 and the secondary filter chamber 91. When it is necessary to switch filter chambers, the controller 954 controls the current magnetic head 951 to be de-energized, the adsorption force disappears, and the drive component 94 can then drive the conveyor head 93 to move along the guide frame 92. This design, through automated and precise adsorption positioning, ensures the smoothness and sealing of the switching of the secondary filter chamber 91, so that the switching process does not require machine downtime. Operators can simultaneously maintain the replaced secondary filter chamber 91, effectively solving the problem of production interruption caused by filter maintenance in the background technology.

[0035] In one embodiment of the present invention, such as Figures 1-6 As shown, the conveying assembly 96 includes a second fan 961, an output pipe 962, and an input pipe 963. The second fan 961 is installed on the top of the dust collection chamber 3. An output pipe 962 is provided between the input end of the second fan 961 and the output end of the primary filter chamber 5, and the two are connected through the output pipe 962. An input pipe 963 is provided between the output end of the second fan 961 and the conveying head 93, and the two are connected through the input pipe 963.

[0036] It should be noted that the conveying assembly 96 described in this embodiment is equipped with a second fan 961, which can provide independent and stable power for the dust conveying after the primary filter chamber 5. This avoids the paralysis of the entire dust collection system due to the failure of a single fan, namely the first fan 6, thus improving the operational reliability of the device. The output pipe 962 connects the output end of the primary filter chamber 5 to the input end of the second fan 961, and the input pipe 963 connects the output end of the second fan 961 to the conveying head 93. The two form a closed dust conveying channel, which can effectively prevent dust leakage during the conveying process and ensure a clean working environment. The connection between the output pipe 962, the input pipe 963 and each component adopts a detachable sealed structure, which not only facilitates the disassembly, maintenance and cleaning of the pipes, but also ensures the sealing of the connection parts, ensuring the high efficiency of dust conveying and providing a stable material guarantee for the continuous secondary filtration.

[0037] Specifically, when the conveying component 96 is working, the second fan 961 starts to generate suction, which draws out the pre-filtered dust from the primary filter chamber 5 through the output pipe 962, and then conveys the dust to the conveying head 93 through the input pipe 963. The conveying head 93 then guides the dust into the currently connected secondary filter chamber 91 for fine filtration. Even during the switching process of the secondary filter chamber 91, the second fan 961 can continue to operate. The dust is continuously conveyed through the input pipe 963 and the movable conveying head 93. This design ensures the continuous transmission of dust from the primary filter chamber 5 to the secondary filter chamber 91. Combined with the non-stop switching of the secondary filter switching mechanism 9, the entire dust collection and filtration process is uninterrupted, completely solving the problem of production interruption caused by the need to stop for filtration maintenance in the background technology.

[0038] In one embodiment of the present invention, such as Figures 1-6 As shown, the secondary filtration chamber 91 includes a protective sleeve 911 and an inner filter plate 912. One end of the protective sleeve 911 passes through the inner wall of the fixing frame 8 and the dust collection chamber 3 in sequence. The inner filter plate 912 is snapped into the inner wall of the protective sleeve 911. The other end of the protective sleeve 911 is flush with one side of the fixing frame 8.

[0039] It should be noted that the secondary filter chamber 91 described in this embodiment adopts a split structure of "protective sleeve plate 911 + filter inner plate 912". The protective sleeve plate 911 can provide physical protection for the filter inner plate 912, preventing the filter inner plate 912 from directly contacting the inner wall of the dust collection chamber 3 or other components and causing wear. At the same time, it can improve the overall structural strength of the secondary filter chamber 91. The filter inner plate 912 is installed on the inner wall of the protective sleeve plate 911 by snap-fit, which is convenient for quick disassembly and replacement without complicated disassembly tools and procedures, reducing maintenance difficulty and operation time. One end of the protective sleeve plate 911 penetrates through the fixing frame 8 and the inner wall of the dust collection chamber 3, and the other end is flush with one side of the fixing frame 8. This ensures the stability of the installation of the secondary filter chamber 91 and provides convenient operating space for the disassembly of the filter inner plate 912. Operators can directly access the protective sleeve plate 911 from the outside of the dust collection chamber 3, which improves the convenience of maintenance.

[0040] Specifically, when the secondary filter chamber 91 is working, dust enters the protective sleeve 911 through the conveyor head 93 and is finely filtered by the inner filter plate 912, which traps fine dust. The purified gas is discharged through the protective sleeve 911. When the inner filter plate 912 needs maintenance due to dust accumulation, the drive component 94 drives the conveyor head 93 to switch to the standby secondary filter chamber 91. The operator can directly pull out the inner filter plate 912 inside the protective sleeve 911 from the outside of the dust collection chamber 3 for cleaning or replacement, and then snap it back into the protective sleeve 911. This detachable design allows the maintenance of the inner filter plate 912 without disassembling the entire secondary filter chamber 91. In addition, with the non-stop switching of the secondary filter switching mechanism 9, the maintenance process does not affect production, effectively solving the problem of needing to stop the machine for maintenance of filter components in the background technology.

[0041] In one embodiment of the present invention, such as Figures 1-6 As shown, a fixed side plate 11 is fixedly connected to the other end of the top of the support platform 1. A discharge pipe 12 is installed on the fixed side plate 11. A connecting pipe 10 is provided between the end of the discharge pipe 12 and one end of a plurality of protective sleeve plates 911, and they are connected through the connecting pipe 10. A threaded sleeve plate is fixedly connected to one end of the discharge pipe 12, and the threaded sleeve plate is sleeved on one end of the protective sleeve plate 911.

[0042] It should be noted that the fixed side plate 11 described in this embodiment is fixed to the top of the support platform 1, providing a stable installation support for the discharge pipe 12, ensuring that the discharge pipe 12 does not shake during the operation of the device, and ensuring the smooth discharge of purified gas. The connecting pipe 10 realizes the connection between multiple protective sleeves 911 and the discharge pipe 12, so that the gas purified by all secondary filter chambers 91 can be discharged through the discharge pipe 12 in a concentrated manner, simplifying the gas discharge path and improving the discharge efficiency. The threaded sleeve at one end of the discharge pipe 12 is sleeved on one end of the protective sleeve 911, which not only ensures the sealing of the connection between the discharge pipe 12 and the protective sleeve 911 to prevent the leakage of purified gas, but also facilitates disassembly. When the protective sleeve 911 or the connecting pipe 10 needs maintenance, the threaded sleeve can be quickly unscrewed to separate the discharge pipe 12 from the protective sleeve 911, improving the convenience of maintenance.

[0043] Specifically, during the gas discharge process, the gas purified by the inner filter plate 912 in each secondary filter chamber 91 flows into the discharge pipe 12 through the corresponding connecting pipe 10 and is finally discharged outside the device. When the inner filter plate 912 corresponding to a certain protective sleeve 911 needs maintenance, the threaded sleeve on the protective sleeve 911 can be unscrewed to pull out the protective sleeve 911 and the inner filter plate 912. Other protective sleeves 911 remain connected to the discharge pipe 12 through the connecting pipe 10, and the purified gas is discharged normally. This design ensures that the gas discharge is not affected when the filter chamber is maintained. Combined with the non-stop switching of the secondary filter switching mechanism 9, it realizes the parallel operation of production and maintenance, effectively solving the problem of needing to stop the machine for filter maintenance in the background technology.

[0044] In one embodiment of the present invention, such as Figures 1-6 As shown, both the drive device 941 and the magnetic head 951 are electrically connected to the controller 954, which is electrically connected to an external power supply.

[0045] It should be noted that the electrical connection design of the drive device 941, magnetic head 951, and controller 954 described in this embodiment realizes centralized automated control of both by the controller 954. This eliminates the need for manual operation of the drive device 941 and magnetic head 951 separately, improving the ease of operation and intelligence of the device. The controller 954 is connected to an external power source, providing stable power support for the entire control system. This ensures precise synchronization of the vertical displacement of the drive device 941 and the adsorption / detachment of the magnetic head 951, avoiding erratic component movements due to unstable power. This centralized control method also facilitates adjusting the switching speed of the drive device 941 and the adsorption timing of the magnetic head 951 according to the amount of dust generated during non-woven bag production, enabling flexible adaptation of the switching rhythm of the secondary filter chamber 91 and improving the device's adaptability to various scenarios. The drive device 941 is a cylinder.

[0046] Specifically, when the device is working, the external power supply powers the controller 954. The controller 954 synchronously controls the start, stop, and displacement stroke of the drive device 941, as well as the power on and off of the magnetic head 951, according to a preset program or manual instructions. When it is necessary to switch the secondary filter chamber 91, the controller 954 first controls the current magnetic head 951 to de-energize, and then starts the drive device 941 to drive the conveyor head 93 to move along the guide frame 92. After reaching the target secondary filter chamber 91 position, the controller 954 controls the corresponding magnetic head 951 to be energized and attracted. The entire switching process is completed automatically by the controller 954 without manual intervention, and the switching is fast and smooth, so that filter maintenance does not require machine downtime, effectively solving the problem of production interruption caused by filter component maintenance in the background technology.

[0047] In summary, the dust collection device for non-woven bag production in this embodiment of the invention, after being powered by an external power source, starts the first fan 6 to create negative pressure in the dust collection chamber 3 to draw in dust. After preliminary filtration by the primary filter chamber 5, the dust is conveyed to the conveyor head 93 by the conveying component 96. The controller 954 controls the drive component 94 to move the conveyor head 93 along the guide frame 92, and precisely docks with the target secondary filter chamber 91 through the adsorption component 95. After fine filtration by the secondary filter chamber 91, the dust is discharged through the connecting pipe 10 and the discharge pipe 12. When the current secondary filter chamber 91 needs maintenance, the controller 954 controls the conveyor head 93 to quickly switch to the backup secondary filter chamber 91. The operator can simultaneously maintain the replaced filter inner plate 912 without stopping the machine, which completely solves the problem of production interruption caused by the need to stop the machine for maintenance of filter components in the background art.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
