Description

Technical Field

[0001] This utility model relates to the field of dust collection technology, and in particular to a dust collection device for sewing FIBCs (Flexible Intermediate Bulk Containers). Background Technology

[0002] In the production of FIBCs (Flexible Intermediate Bulk Containers), the sewing process is an indispensable and crucial step. When the sewing machine is working, intense friction occurs between the needle, thread, and the woven fabric of the FIBC, resulting in the generation of a large amount of fiber debris. If this fiber debris is not cleaned up promptly and effectively, it will cause numerous problems.

[0003] Existing technologies, such as the utility model patent with publication number CN 215481691 U, disclose a sewing machine with a dust-collecting device. The sewing machine body includes a worktable, and a sewing machine head is located above the worktable. The key feature is that a mounting platform is located on the side of the sewing machine head, and a dust-collecting head is mounted on the mounting platform. A telescopic mechanism connects the dust-collecting head to the mounting platform. A collection cover is located below the worktable, and the collection cover is connected to a dust-collecting mechanism. The dust-collecting head is connected to a dust-collecting pipe, and the dust-collecting pipe is connected to the dust-collecting mechanism. This sewing machine can absorb waste during sewing, effectively protecting human health and the surrounding environment.

[0004] Existing technologies are difficult to use to efficiently and accurately target the source of fiber debris—the sewing machine needle—resulting in poor dust collection. As a result, a large amount of fiber debris remains in the workshop air, polluting the workshop environment and affecting workers' health.

[0005] To address the aforementioned problems, this utility model provides a dust extraction device for sewing container bags. Utility Model Content

[0006] The purpose of this invention is to solve the problem of poor dust collection effect during the sewing process of FIBCs, which easily pollutes the workshop environment and affects the health of workers. Therefore, this invention proposes a dust collection device for sewing FIBCs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum cleaner for sewing FIBCs, comprising a support frame, a vacuuming mechanism and a connecting and fixing mechanism, wherein the vacuuming mechanism and the connecting and fixing mechanism are fixedly connected to the inside of the support frame, and universal wheels are fixedly connected to the four corners of the bottom of the support frame, and the vacuuming mechanism includes a connecting port fixedly connected to the top of the support frame.

[0008] The dust collection mechanism includes a protective plate and a suction duct, with the protective plate slidably connected to the inside of the connection port.

[0009] The connection port has a sliding groove inside, and the protective plate is slidably connected to the inside of the connection port through the sliding groove. Ventilation holes are provided on both sides of the protective plate. One end of the suction pipe is snapped onto the outer surface of the connection port, and the other end of the suction pipe is snapped onto a dust collection frame. The inner bottom wall of the dust collection frame has a through hole, and a connecting plate is threadedly connected to the inner bottom wall of the dust collection frame. A dust-proof mesh is fixedly connected inside the connecting plate.

[0010] Furthermore, the connecting plate is threaded with connecting parts on both sides, the connecting plate and the dust screen are threaded to the inner bottom wall of the dust collection frame, and the bottom of the dust collection frame is threaded with limiting parts on both sides.

[0011] Furthermore, a limiting plate is fixedly connected to the outer surface of the connection port, one end of the connection port is snapped into the top of the support frame, and the other end of the connection port is snapped into the bottom of the support frame.

[0012] Furthermore, the dust collection mechanism is fixedly connected to a fixed plate on the outer surface of the support frame. A connecting frame is fixedly connected to the bottom of the fixed plate. A servo motor is fixedly connected inside the connecting frame. A suction fan is fixedly connected to the output end of the servo motor. The dust collection frame is threadedly connected to the top of the fixed plate through a limiting member.

[0013] Furthermore, the connection and fixing mechanism includes an interface connection component and a fixing component. There are two interface connection components, which are snapped onto both ends of the suction pipe. The two ends of the suction pipe are respectively snapped onto the connection port and the outer surface of the dust collection frame through the interface connection components.

[0014] Furthermore, the interface connection assembly includes connecting clamps that snap onto both ends of the suction duct, with limit bolts threaded to both ends of the connecting clamps, and limit nuts threaded to the outer surface of the limit bolts.

[0015] Furthermore, the fixing component includes a connecting semi-circular ring threaded to the outer surface of the suction duct, fasteners threaded to both sides of the connecting semi-circular ring, the connecting semi-circular ring being threaded to the outer surface of the suction duct by means of fasteners, and a connecting post fixedly connected to the top of the connecting semi-circular ring, the top of the connecting post being threaded to the bottom of the support frame.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by setting up a protective plate, a suction duct, and a dust filter, the protective plate can effectively block larger debris from entering the suction duct, preventing debris from damaging the internal structure of the duct and components such as the suction fan, thus protecting the integrity of the internal structure. Under the action of the suction fan driven by the servo motor, the suction duct can quickly form a stable negative pressure environment, which promptly sucks the fiber scraps and dust generated during the sewing machine's operation into the dust collection frame, greatly improving the dust collection efficiency. The dust filter can firmly intercept dust and prevent it from leaking from the through hole at the bottom of the dust collection frame, ensuring that the dust and scraps are completely collected in the dust collection frame, avoiding secondary pollution, and significantly purifying the workshop environment.

[0018] 2. In this utility model, by using connecting clamps, connecting semicircular rings, and connecting columns, the connecting clamps, in conjunction with limiting bolts and limiting nuts, can tightly secure both ends of the suction pipe to the connection port and the dust collection frame respectively, effectively preventing loosening or detachment at the connection points, ensuring the airtightness of the suction pipe, and avoiding a decrease in dust collection efficiency due to air leakage. The connecting semicircular ring is fixed to the outer surface of the suction pipe with fasteners, and then connected to the bottom of the support frame with the help of connecting columns, fixing it from the middle of the suction pipe and other multiple positions, further enhancing the stability of the suction pipe installation, making the entire device structure more reliable, reducing malfunctions caused by pipe shaking or displacement, and extending the service life of the device.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a vacuum cleaner for sewing container bags, including a support frame 1, a vacuuming mechanism 2 and a connecting and fixing mechanism 3. The vacuuming mechanism 2 and the connecting and fixing mechanism 3 are fixedly connected to the inside of the support frame 1. Universal wheels 4 are fixedly connected to the four corners of the bottom of the support frame 1. The vacuuming mechanism 2 includes a connecting port 21 fixedly connected to the top of the support frame 1.

[0028] The following section will explain the specific setup and function of its vacuuming mechanism 2 and connecting and fixing mechanism 3.

[0029] In this embodiment: the dust collection mechanism 2 includes a protective plate 22 and a suction duct 23, and the protective plate 22 is slidably connected to the inside of the connection port 21.

[0030] The interior of the connection port 21 is provided with a sliding groove 24. The protective plate 22 is slidably connected to the interior of the connection port 21 through the sliding groove 24. Ventilation holes 25 are provided on both sides of the protective plate 22. One end of the suction pipe 23 is snapped onto the outer surface of the connection port 21, and the other end of the suction pipe 23 is snapped onto a dust collection frame 26. The inner bottom wall of the dust collection frame 26 is provided with a through hole 27. The inner bottom wall of the dust collection frame 26 is threadedly connected to a connecting plate 28. A dust-proof net 29 is fixedly connected inside the connecting plate 28.

[0031] The effects achieved by the above components are as follows: the connecting port 21 is located at the bottom of the needle of the sewing machine; the sliding groove 24 inside the connecting port 21 provides a sliding track for the protective plate 22, allowing the protective plate 22 to slide flexibly inside the connecting port 21; the ventilation holes 25 on both sides of the protective plate 22 can block larger debris from entering the suction pipe 23 without obstructing the airflow, thus playing a preliminary filtering and protection role; the suction pipe 23 connects the connecting port 21 and the dust collection frame 26, forming a dust conveying channel, allowing the dust sucked in from the connecting port 21 to smoothly enter the dust collection frame 26; the through hole 27 on the bottom wall of the dust collection frame 26 can balance the air pressure inside the frame; the dust screen 29 inside the connecting plate 28 can effectively intercept dust and prevent dust from leaking out from the through hole 27, ensuring that the dust is reliably collected in the dust collection frame 26.

[0032] Specifically, the connecting plate 28 is threaded with connecting parts 210 on both sides, the connecting plate 28 and the dust screen 29 are threaded to the inner bottom wall of the dust collection frame 26, and the bottom of the dust collection frame 26 is threaded with limiting parts 211 on both sides.

[0033] The aforementioned components achieve the following effects: the connecting parts 210 on both sides of the connecting plate 28 firmly fix the connecting plate 28 and the dust filter 29 to the inner bottom wall of the dust collection frame 26, preventing the connecting plate 28 and the dust filter 29 from loosening or shifting due to airflow impact during dust collection, thus ensuring the stability of the dust separation effect. The limiting parts 211 on both sides of the bottom of the dust collection frame 26 limit the installation position of the dust collection frame 26, ensuring that the dust collection frame 26 is precisely connected to other components, thereby improving the overall stability of the device.

[0034] Specifically, a limiting plate 212 is fixedly connected to the outer surface of the connection port 21, one end of the connection port 21 is snapped into the top of the support frame 1, and the other end of the connection port 21 is snapped into the bottom of the support frame 1.

[0035] The effects achieved by the above components are as follows: the limiting plate 212 on the outer surface of the connection port 21 enhances the connection strength between the connection port 21 and the support frame 1, preventing the connection port 21 from shaking during device operation. The design of one end of the connection port 21 being snapped into the top of the support frame 1 and the other end being snapped into the bottom of the support frame 1 makes the connection port 21 more securely installed in the support frame 1, providing a stable inlet structure for the dust collection process.

[0036] Specifically, the dust collection mechanism 2 is fixedly connected to the fixing plate 213 on the outer surface of the support frame 1. The bottom of the fixing plate 213 is fixedly connected to the connecting frame 214. The inside of the connecting frame 214 is fixedly connected to the servo motor 215. The output end of the servo motor 215 is fixedly connected to the suction fan 216. The dust collection frame 26 is threadedly connected to the top of the fixing plate 213 through the limiting member 211.

[0037] The effects achieved by the above components are as follows: the fixing plate 213 provides a stable installation base for the dust collection frame 26 and the connecting frame 214, while the connecting frame 214 protects the internal servo motor 215 from external interference. The servo motor 215 serves as a power source, and the suction fan 216 at its output end generates negative pressure when rotating, providing power for the entire dust collection process and causing dust to enter the dust collection frame 26 along the connecting port 21 and the suction pipe 23. The dust collection frame 26 is threadedly connected to the top of the fixing plate 213 through the limiting member 211, ensuring the firmness of the installation of the dust collection frame 26 and preventing displacement when the suction fan 216 vibrates during operation.

[0038] Specifically, the connecting and fixing mechanism 3 includes an interface connecting component 31 and a fixing component 32. There are two interface connecting components 31. The interface connecting components 31 are snapped onto both ends of the suction pipe 23. The two ends of the suction pipe 23 are respectively snapped onto the outer surface of the connecting port 21 and the dust collection frame 26 through the interface connecting components 31.

[0039] The effect achieved by the above components is as follows: There are two interface connection components 31, which are respectively snapped into both ends of the suction pipe 23, tightly connecting the suction pipe 23 with the connection port 21 and the dust collection frame 26, effectively preventing air leakage at the connection between the suction pipe 23 and these two components, ensuring the negative pressure environment inside the pipe, and ensuring the dust collection effect.

[0040] Specifically, the interface connection component 31 includes a connecting clamp 311 that snaps into both ends of the suction pipe 23, with limit bolts 312 threadedly connected to both ends of the connecting clamp 311, and limit nuts 313 threadedly connected to the outer surface of the limit bolts 312.

[0041] The effects achieved by the above components are as follows: the connecting clamp 311 in the interface connection assembly 31 can tightly wrap the connection part between the suction pipe 23 and the connection port 21 and the dust collection frame 26. The limiting bolt 312 and the limiting nut 313 can enhance the clamping force of the connecting clamp 311 by tightening, which further improves the sealing and firmness of the connection between the suction pipe 23 and other components, and reduces the problem of reduced dust collection efficiency caused by loose connection.

[0042] Specifically, the fixing component 32 includes a connecting semi-circular ring 321 threadedly connected to the outer surface of the suction duct 23, fasteners 322 threadedly connected to both sides of the connecting semi-circular ring 321, the connecting semi-circular ring 321 being threadedly connected to the outer surface of the suction duct 23 through the fasteners 322, and a connecting post 323 fixedly connected to the top of the connecting semi-circular ring 321, the top of the connecting post 323 being threadedly connected to the bottom of the support frame 1.

[0043] The effect achieved by the above components is as follows: the connecting semi-circular ring 321 in the fixing component 32 is firmly fixed to the outer surface of the suction pipe 23 by the fastener 322, and the connecting column 323 connects the connecting semi-circular ring 321 to the bottom of the support frame 1 and fixes it from the middle of the suction pipe 23, effectively preventing the suction pipe 23 from bending or shaking under negative pressure, enhancing the overall stability of the suction pipe 23, and ensuring the smooth transport of dust and debris.

[0044] Working principle: When the device starts working, the servo motor 215 starts, driving the suction fan 216 to rotate at high speed, creating a negative pressure in the suction pipe 23. At this time, the dust generated by the sewing machine is sucked into the connection port 21 under the action of the external atmospheric pressure.

[0045] During the process of entering the connection port 21, the protective plate 22 performs preliminary filtration of dust and debris through the ventilation holes 25, blocking larger debris. The filtered dust and debris are transported to the dust collection frame 26 along the suction pipe 23. The dust filter 29 intercepts the dust and debris in the dust collection frame 26, completing the collection of dust and debris.

[0046] Throughout the process, the various components of the connecting and fixing mechanism 3 ensure the firmness and sealing of the connection of components such as the suction duct 23. The casters 4 at the bottom of the support frame 1 allow the device to be moved to a suitable working position as needed, ensuring efficient and stable dust collection. When the dust in the dust collection frame 26 accumulates to a certain amount, the connecting plate 28 and the dust filter 29 can be removed by disassembling the connector 210 for cleaning. After cleaning, they can be reinstalled for continued use.
