Abstract
Description
Technical Field
[0001] This utility model belongs to the field of insulating tube machining technology, specifically relating to a high-efficiency dust removal device for insulating tube machining. Background Technology
[0002] Insulating tubes are commonly used protective components in the power, communications, and other industrial sectors, and their processing quality directly affects product performance and lifespan. The cutting and processing of insulating tubes typically generates a large amount of dust and debris. If this dust is not effectively controlled, it can lead to several problems: firstly, dust pollutes the working environment and affects the health of operators; secondly, dust accumulation can affect the normal operation of equipment and even reduce processing accuracy. Therefore, the proper design of dust removal devices is crucial in the processing of insulating tubes.
[0003] Currently, dust collection devices used in the processing of insulating tubes mainly employ fixed dust hoods or external dust collection devices. However, existing technologies generally have the following shortcomings:
[0004] 1. Poor sealing and limited dust removal effect: Existing dust removal devices often use fixed covers or external suction pipes to collect dust. However, due to the large gaps between the cover and the pipe, dust is prone to leakage, resulting in unsatisfactory dust removal effect. Especially when processing insulating pipes of different diameters, fixed suction covers are difficult to adapt to changes in pipe size, causing dust to spread.
[0005] 2. Unstable tube fixation affects processing accuracy: Some dust removal devices fail to be effectively integrated with the clamping mechanism, which may cause the tube to shake or shift during processing, affecting the cutting quality and increasing the possibility of dust diffusion.
[0006] 3. Inconvenient cleaning and high maintenance costs: Existing devices rely heavily on manual cleaning or regular filter replacement after collecting dust. These methods are often inefficient, resulting in high equipment maintenance costs and affecting production efficiency. Utility Model Content
[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-efficiency dust removal device for machining insulating tubes. This device achieves adaptive sealing for tubes of different diameters through an adjustable dustproof strip structure, effectively preventing dust leakage. Simultaneously, the device incorporates a centering and clamping mechanism to ensure stable fixation of the tube, improving cutting accuracy. Furthermore, the device is equipped with a dust pump and a dust collection box, which can effectively collect and centrally process dust, improving dust removal efficiency and the working environment.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A high-efficiency dust removal device for machining insulating tubes includes a workbench and a tube body. The workbench is horizontally placed on one side of a cutting machine. A centering clamping mechanism is symmetrically arranged on the upper surface of the workbench. The tube body is horizontally passed through two centering clamping mechanisms and clamped and fixed. A protective box is installed between the two centering clamping mechanisms, covering the tube body. A cutting groove is formed at the center of the surface of the protective box. A mounting through groove is symmetrically formed at both ends of the upper surface of the protective box. Dustproof strips are uniformly and vertically slidably installed inside the mounting through grooves. The bottom of multiple dustproof strips is in contact with the arc of the tube body surface. Multiple dustproof strips seal both sides of the protective box. A fixing bolt is provided on the top of each dustproof strip near the cutting groove. The fixing bolt is placed above the protective box.
[0010] Furthermore, both sides of the protective box are symmetrically welded with protrusions, which correspond to the positions of the mounting slots. A sliding rod is vertically slidably installed on the inner side of the protrusion, and a crossbar is fixed between the tops of the two sliding rods. The crossbar is horizontally placed above the protective box and below the multiple fixing bolts.
[0011] Furthermore, the bottom of the slide bar is provided with a compression ball head, and the protective box is rotatably installed on both sides below the tube body, with the rotating shafts placed vertically below the tube body.
[0012] Furthermore, the rotating shaft extends through both sides of the protective housing, a knob is provided at one end of the rotating shaft, and eccentric wheels are symmetrically arranged on the surface of the rotating shaft. The two eccentric wheels are respectively placed on the outside of the protective housing, and the extrusion ball head contacts the curved surface of the eccentric wheel.
[0013] Furthermore, the centering clamping mechanism includes a frame fixed on both sides of the workbench surface, a fixed V-block installed on the lower inner side of the frame, a pressing screw vertically screwed onto the top of the frame, a movable V-block installed at the bottom of the pressing screw, and the tube placed between the fixed V-block and the movable V-block.
[0014] Furthermore, the two frames are symmetrically provided with sliding grooves on their adjacent sides, and the two ends of the protective box slide inside the sliding grooves respectively, with the lower half of the frame sealing the bottom of the open protective box.
[0015] Furthermore, a dust collection box is slidably installed on the lower side of one side of the protective housing, and the dust collection box is positioned directly below the cutting groove.
[0016] Furthermore, a dust pump is provided on one side of the workbench, and the dust pump input is connected to two hoses. The ends of the two hoses are respectively installed on the top of the protective box, and the two hoses are placed on both sides of the cutting groove.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This utility model provides a high-efficiency dust removal device for machining insulating tubes. By setting a centering clamping mechanism on the worktable and employing a combination of fixed and movable V-blocks, the tube body can be stably clamped during processing, preventing a decrease in machining accuracy due to vibration or displacement. By rotating the extrusion screw, the movable V-block can be adjusted according to different tube diameters, ensuring a close fit between the tube body and the clamping mechanism, improving the tube's stability, and thus effectively reducing errors caused by displacement during cutting, thereby improving machining quality.
[0019] This invention features sliding dustproof strips on both sides of the protective housing, along with an adjustable fixing bolt structure. This allows the dustproof strips to adapt to pipes of different diameters. Before cutting, rotating a knob moves an eccentric wheel, raising the fixing bolt and placing the dustproof strip at its highest position for easy pipe insertion. Once the pipe is fixed, the eccentric wheel stops pressing, and the dustproof strip automatically falls back under gravity to adhere to the pipe surface, sealing the end of the protective housing and effectively preventing dust leakage. Compared to traditional fixed dust hood structures, this invention automatically adapts to different pipe diameters, improving sealing performance, reducing dust diffusion, and optimizing the processing environment.
[0020] This invention features a dust collection box at the bottom of the protective housing, directly opposite the cutting groove. This allows dust and debris falling during cutting to directly enter the dust collection box, preventing dust from scattering. Simultaneously, the dust collection box contains a replaceable filter for further dust filtration, preventing long-term dust accumulation from affecting equipment operation and improving cleaning convenience. Compared to traditional dust removal methods, this structure achieves centralized dust collection, reducing the frequency of manual cleaning and extending equipment lifespan.
[0021] This invention features a dust pump installed at the top of the protective housing, connected to both sides of the housing via flexible hoses. During operation, the pump directly extracts dust generated during the cutting process, preventing dust from accumulating inside the housing. The hose arrangement ensures that dust generated during cutting is quickly sucked away, preventing it from spreading through the air, further improving dust removal efficiency, reducing the harm of dust to operators, and improving the processing environment. Compared to traditional dust removal devices, this design controls dust diffusion at the source, improving the environmental performance of the production process.
[0022] This invention optimizes the sliding structure of the protective housing, allowing both ends to slide within the grooves of the centering clamping mechanism. The lower half of the frame seals the bottom of the protective housing, preventing dust leakage. This design not only enhances the stability of the protective housing but also improves the sealing effect of the dust collection system, making the entire dust collection system more efficient, reducing secondary pollution caused by dust leakage, optimizing the working environment for operators, and improving the practicality of the equipment.

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0032] Example 1:
[0033] refer to Figures 1-6As shown, a high-efficiency dust removal device for machining insulating tubes includes a workbench 1 and a tube body 3. The workbench 1 is made of Q235 carbon steel to ensure the strength and durability of the overall structure. The workbench 1 is horizontally placed on one side of the cutting machine. A centering clamping mechanism 2 is symmetrically arranged on the upper surface of the workbench 1 to achieve stable positioning of the tube body 3, preventing vibration or displacement from affecting machining accuracy during cutting. The tube body 3 horizontally passes through two centering clamping mechanisms 2 and is clamped and fixed. The tube body 3 is an insulating tube with a diameter ranging from 20mm to 100mm, and its surface has a certain wear-resistant coating to improve its service life. A protective box 4 is installed between the two centering clamping mechanisms 2, covering the tube body 3. The protective box 4 is made of aluminum alloy to reduce the overall weight while improving corrosion resistance. A cutting groove 41 with a width of 10mm is opened at the center of the surface of the protective box 4. To ensure smooth cutting and effective control of dust diffusion, the upper surface of the protective housing 4 is symmetrically provided with mounting slots 42 at both ends. The width of the mounting slots 42 matches that of the dustproof strips 5, allowing the dustproof strips 5 to slide vertically within the mounting slots 42. Multiple dustproof strips 5 are uniformly and vertically mounted on the inner side of the mounting slots 42. These strips are made of high-temperature resistant silicone to ensure they are not affected by high temperatures during cutting and to prevent dust leakage. The bottoms of the multiple dustproof strips 5 are in contact with the arc of the tube body 3 surface to ensure a sealing effect and prevent dust from spreading outwards during cutting. The multiple dustproof strips 5 seal both sides of the protective housing 4, improving dust removal efficiency. A fixing bolt 51 is provided on the top of each dustproof strip 5 near the cutting groove 41. The fixing bolt 51 is made of stainless steel and is positioned above the protective housing 4. The fixing bolt 51 is raised and lowered synchronously by adjusting the crossbar 7 to adapt to the processing requirements of tube bodies 3 with different diameters.
[0034] refer to Figure 3 and Figure 4 As shown, symmetrical protrusions 43 are welded on both sides of the protective box 4. The protrusions 43 correspond to the mounting slots 42. The material of the protrusions 43 is the same as that of the protective box 4 to ensure structural stability. A sliding rod 6 is vertically slidably installed on the inner side of the protrusion 43. The sliding rod 6 is made of high-strength alloy steel and chrome-plated to reduce frictional resistance and improve sliding stability. A crossbar 7 is fixed between the tops of the two sliding rods 6. The diameter of the crossbar 7 is 10mm to provide sufficient support. The crossbar 7 is horizontally placed above the protective box 4 and below multiple fixing bolts 51. When the knob 81 is rotated, the crossbar 7 can drive the fixing bolts 51 to move upward through the sliding rods 6 so that the pipe 3 can pass smoothly through the protective box 4.
[0035] refer to Figure 3 and Figure 6As shown, the bottom of the slide bar 6 is provided with a compression ball head 61. The compression ball head 61 is made of high-strength nylon material to reduce friction on the surface of the eccentric wheel 9 and ensure long-term durability. The protective box 4 is rotatably mounted on both sides below the protective box 4. The rotating shaft 8 is made of 40Cr alloy steel to ensure sufficient torsional strength. The rotating shaft 8 is placed vertically below the tube body 3 to ensure that the dustproof strip 5 can be smoothly driven to rise and fall during operation.
[0036] refer to Figure 6 As shown, the rotating shaft 8 runs through both sides of the protective housing 4. The diameter of the rotating shaft 8 is 12mm, and it is supported by double-end bearings to reduce rotational friction and improve service life. A knob 81 with a diameter of 50mm is provided at one end of the rotating shaft 8 for easy manual adjustment by the operator. Eccentric wheels 9 are symmetrically arranged on the surface of the rotating shaft 8. The eccentric wheels 9 are made of aluminum alloy and have been anodized to improve their wear resistance and corrosion resistance. The two eccentric wheels 9 are respectively placed on the outside of the protective housing 4. The extrusion ball head 61 contacts the curved surface of the eccentric wheel 9. By rotating the rotating shaft 8, the eccentric structure of the eccentric wheel 9 can drive the extrusion ball head 61 to move up or down, thereby driving the crossbar 7 to lift or release the fixing bolt 51, so as to realize the automatic adjustment function of the dustproof strip 5.
[0037] refer to Figure 1 and Figure 5 As shown, the centering clamping mechanism 2 includes a frame 21 fixed on both sides of the upper surface of the worktable 1. The frame 21 is made of Q235 carbon steel and is fixed to the worktable 1 with bolts to ensure overall rigidity. A fixed V-block 23 is installed on the lower inner side of the frame 21. The fixed V-block 23 is made of 45 steel and has been heat-treated to improve its wear resistance and service life. A pressing screw 22 is vertically screwed onto the top of the frame 21. The pressing screw 22 is made of stainless steel and nitrided on the threaded part to improve its wear resistance and rust prevention. A movable V-block 24 is installed at the bottom of the pressing screw 22. The movable V-block 24 corresponds to the fixed V-block 23. The tube 3 is placed between the fixed V-block 23 and the movable V-block 24. By rotating the pressing screw 22, the height of the movable V-block 24 can be adjusted to meet the clamping requirements of tubes 3 of different diameters and ensure the stability of the tube 3 during processing.
[0038] refer to Figure 1 As shown, two frames 21 are symmetrically provided with sliding grooves 211 on their adjacent sides. The width of the sliding grooves 211 is 15mm, which can meet the sliding adjustment requirements of the protective box 4. The two ends of the protective box 4 slide on the inner side of the sliding grooves 211 to ensure that the protective box 4 can remain stable during the cutting process. The lower half of the frame 21 seals the bottom of the open part of the protective box 4 to prevent dust from leaking from the bottom during the cutting process.
[0039] refer to Figure 1 and Figure 3 As shown, a dust collection box 44 is slidably installed on the lower side of one side of the protective housing 4. The dust collection box 44 is made of stainless steel and has a replaceable filter inside to facilitate the centralized collection and treatment of dust. The dust collection box 44 is placed directly below the cutting groove 41 to ensure that the dust falling during the cutting process can be collected smoothly and reduce dust pollution.
[0040] refer to Figure 1 and Figure 2 As shown, a dust pump 10 is installed on one side of the workbench 1. The dust pump 10 has a power of 750W and can provide sufficient suction to efficiently collect dust. The dust pump 10 has two hoses 11 connected to its input. The two hoses 11 are made of high-temperature and corrosion-resistant PVC material and have an anti-static coating on their inner walls to reduce dust adsorption. The ends of the two hoses 11 are respectively installed on the top of the protective box 4 and are placed on both sides of the cutting groove 41. This can effectively suck up the dust generated during the cutting process, thereby improving dust removal efficiency and improving the working environment.
[0041] Example 2: High-precision clamping and fixing structure for tube body
[0042] This embodiment provides a high-precision clamping and fixing structure for pipes. This structure uses a centering clamping mechanism 2 to fix the pipe to prevent it from shifting during cutting and improve processing accuracy. The centering clamping mechanism 2 mainly consists of a frame 21, a fixed V-block 23, a movable V-block 24, and a pressing screw 22. The frame 21 is made of Q235 carbon steel, which can provide high strength and stability. The fixed V-block 23 and the movable V-block 24 are both made of 45 steel and have undergone quenching treatment to enhance wear resistance and hardness.
[0043] In use, the tube body 3 horizontally passes through two centering clamping mechanisms 2 and is positioned between the fixed V-block 23 and the movable V-block 24. When the extrusion screw 22 is rotated, the movable V-block 24 moves downward and fits tightly against the tube body surface, thus forming a stable clamping force. The extrusion screw 22 is made of 304 stainless steel, and the threaded portion is nitrided to improve wear resistance and service life. The screw diameter is set at 12mm, providing sufficient clamping force to keep the tube body stable during cutting. In addition, the V-block angle is designed to be 90°, suitable for tube bodies with a diameter range of 20mm-100mm, ensuring clamping stability.
[0044] Comparative Case: Problems with Traditional Clamping Methods
[0045] Traditional pipe clamping methods typically employ simple C-clamps or spiral clamping devices, but these methods have significant limitations. For example, C-clamps are only suitable for pipes of a specific size and cannot automatically adjust to accommodate different pipe diameters, leading to problems such as pipe loosening or excessive clamping during processing. While spiral clamping devices offer some adjustment, their small clamping force point can easily cause localized stress concentration on the pipe surface, resulting in pipe deformation and affecting cutting accuracy. In contrast, the V-block clamping method used in this embodiment ensures uniform force distribution on the pipe, and the adjustable movable V-block 24 is suitable for pipes of different diameters, improving clamping stability and processing accuracy.
[0046] Example 3: Adjustable dustproof strip sealing structure
[0047] This embodiment provides an adjustable dustproof strip sealing structure. This structure employs components such as a dustproof strip 5, a fixing bolt 51, a sliding rod 6, a crossbar 7, a compression ball head 61, and an eccentric wheel 9 to achieve adaptive sealing for pipes of different diameters, preventing dust leakage during processing. The dustproof strip 5 is made of high-temperature resistant silicone material, capable of withstanding temperatures up to 200℃, and possesses good flexibility and sealing performance. The width of the mounting groove 42 is set to 8mm to ensure that the dustproof strip 5 can slide smoothly within it without jamming.
[0048] In use, rotating knob 81 drives shaft 8 to rotate. Two eccentric wheels 9 are fixed to the surface of shaft 8. The eccentric wheels 9 are made of 6061 aluminum alloy and have undergone anodizing treatment to improve wear resistance. After the eccentric wheels 9 rotate, the extrusion ball head 61 in contact with them moves upward synchronously, thereby driving the slide bar 6 and crossbar 7, causing multiple fixing bolts 51 to rise synchronously. At this time, the dustproof strip 5 is at its highest position, and the tube body 3 can smoothly pass through the protective box 4. When the tube body 3 is in place, knob 81 rotates in the opposite direction, the eccentric wheels 9 no longer apply pressure, and the dustproof strip 5 descends due to gravity and fits tightly against the surface of the tube body 3, achieving a good sealing effect.
[0049] Comparative Case Study: Limitations of Traditional Dustproof Designs
[0050] Traditional dustproof designs typically employ fixed sealing strips or single-size dust covers, both of which have significant shortcomings in sealing performance. For example, fixed sealing strips are usually only suitable for pipes of a specific diameter; when the pipe diameter changes, the sealing strip cannot provide a good fit, leading to dust leakage. Single-size dust covers, on the other hand, have considerable limitations in sealing, especially during pipe insertion and removal, often requiring manual disassembly or adjustment, which is cumbersome and can negatively impact production efficiency. In contrast, the adjustable dust strip structure provided in this embodiment can automatically adapt to pipes of different diameters and can be dynamically adjusted before and after cutting, improving both sealing performance and ease of operation.
[0051] Example 4: High-efficiency dust collection and treatment system
[0052] This embodiment provides a high-efficiency dust collection and treatment system. The system employs components such as a dust collection box 44, a dust pump 10, and a flexible hose 11 to efficiently collect dust generated during the cutting process. The dust collection box 44 is made of 304 stainless steel with a mirror-polished surface to reduce dust adhesion. It also contains a replaceable filter made of HEPA high-efficiency filter material, which can effectively filter 99.97% of particulate dust.
[0053] During use, the dust collection box 44 is placed directly below the cutting groove 41. Dust and debris generated during the cutting process will fall directly into the dust collection box, preventing dust from spreading. In addition, the bottom of the dust collection box has a drawer-type structure, which facilitates regular cleaning of the dust.
[0054] Meanwhile, the dust removal system in this embodiment is equipped with a 750W dust pump 10. The dust pump is connected to the top of the protective housing 4 through two high-temperature resistant PVC hoses 11. The hoses have a diameter of 40mm, which can ensure sufficient suction. During the cutting process, the dust pump will generate a vacuum pressure of 8kPa to quickly suck away the dust in the cutting area, thereby preventing the dust from spreading.
[0055] Comparative Case: Deficiencies of Traditional Dust Collection Methods
[0056] Traditional dust collection methods typically rely on independent external vacuum cleaners, which often use a single suction pipe or an open dust collection box, resulting in incomplete dust collection. For example, while a single suction pipe can remove some dust, the wide dispersion of dust during cutting means a significant amount remains uncollected. Open dust collection boxes, on the other hand, have poor dust settling properties and can still cause secondary pollution during operation. In contrast, the dust collection system in this embodiment employs a dual-channel suction system combined with a dust collection box, enabling efficient dust filtration and centralized processing. This improves dust collection efficiency, reduces equipment maintenance costs, and enhances environmental performance.
[0057] Through the above embodiments, this utility model achieves an overall improvement in high-precision clamping of the tube body, optimized dustproof strip sealing, and efficient dust collection. Compared with traditional equipment, it has significant improvements in processing accuracy, dust control, and ease of operation, providing a better technical solution for the efficient processing of insulating tubes.
[0058] The working principle of this utility model is as follows: First, the protective box 4 and the centering clamping mechanism 2 are installed, and both ends of the protective box 4 slide inside the groove 211 respectively. At this time, the lower part of the open ends of the protective box 4 is sealed by the lower half of the centering clamping mechanism 2. Then, the tube 3 passes through one side of the centering clamping mechanism 2, and the knob 81 is rotated to drive the eccentric wheel 9 to rotate. The two eccentric wheels 9 drive the extrusion ball head 61 to move upward, and then the crossbar 7 pushes the multiple fixing bolts 51 to move upward, so that the dustproof strip 5 is placed at the top of the stroke. At this time, the dustproof strip 5 will not affect the insertion of the tube 3. After the tube 3 passes through the other centering clamping mechanism 2, the cutting position is adjusted to correspond with the cutting groove 41. Then, the knob 81 is rotated in the opposite direction so that the eccentric wheel 9 no longer squeezes the extrusion ball head 61 upward. At this time, the dustproof strips 5 will fall downwards due to their own weight, so that multiple dustproof strips 5 can automatically adapt to tubes 3 of different diameters. Multiple dustproof strips 5 will seal the upper part of the end of the protective box 4 to prevent dust and debris generated by the protective box 4 during cutting from leaking through both ends of the protective box 4, thereby improving the dustproof efficiency. Before cutting, the rotating extrusion screw 22 is used to control the moving V-block 24 to move downwards, thereby clamping and fixing the tube 3 to prevent the tube 3 from shifting during cutting. The saw cuts the tube 3 downwards through the cutting groove 41. The powder generated during cutting will fall into the dust collection box 44 for subsequent centralized treatment. The dust pump 10 is started during cutting. At this time, the dust generated during cutting is placed inside the protective box 4, and the dust inside the protective box 4 is sucked out through the hose 11 to achieve the purpose of dust removal during processing.
[0059] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
