Description

Technical Field

[0001] This invention relates to the field of industrial vacuum cleaner technology, and more particularly to a high-power vacuum cleaner for cutting tables. Background Technology

[0002] Cutting tables typically refer to automatic or semi-automatic machines used in industries such as clothing, bags, furniture, and automotive interiors for cutting fabrics or composite materials. These machines produce a layer of residual edge fibers called a "brittle layer" when cutting fabric edges, seams, and hemming. These "brittle fibers" are portions of fabric fibers that are cut or pulled out during the cutting process. They are usually loose, fibrous, and electrostatically attracted, and sometimes contain dust, fiber lint, dyes, oil, or processing oil generated during the cutting process. Because the fibers are loose, they are easily carried, dispersed, or sucked into dust collection systems by airflow. If not handled promptly or effectively, they accumulate in the machinery, blades, or tracks, causing equipment wear, reduced cutting accuracy, and fabric waste. Some factories have basic fans or dust hoods to remove the brittle fibers from the fabric worktable, but their efficiency is limited.

[0003] Traditional cutting table vacuum cleaners have several problems. Firstly, most traditional vacuum cleaners have a single suction port, which often cannot fully cover the working area of ​​the cutting table's bristles. This results in some areas of fabric fibers not being effectively removed, leading to poor cleaning. Furthermore, if the suction port becomes clogged, the vacuum cleaner cannot function properly, affecting work efficiency. Some vacuum cleaners use a multi-collection tube structure, but the airflow from adjacent collection tubes can easily interfere with each other, causing uneven negative pressure distribution in each collection tube chamber. This prevents some collection tubes from obtaining stable suction, thus reducing overall vacuuming efficiency. Moreover, the direct convergence of airflow from different collection tube openings can create turbulence and oscillation, causing equipment vibration. Secondly, traditional vacuum cleaners cannot flexibly adjust suction power according to the fabric fiber load in different areas. When fabric fibers are particularly concentrated in a certain area or a collection tube is clogged, the suction power cannot be concentrated in time to address the problem, resulting in poor cleaning performance. In addition, the inhaled gas carries fiber debris that swirls around inside the dust collection box and adheres to the inner wall of the box, making it difficult to remove. This accumulation can also create new sources of dust. The inner walls and the upper part of the box often lack mechanical cleaning or automatic dust removal measures, requiring manual cleaning, which increases maintenance costs and downtime. Summary of the Invention

[0004] The purpose of this invention is to provide a high-power vacuum cleaner for cutting tables. This high-power vacuum cleaner can cover the working area of ​​the cutting table bristles, and the airflow of adjacent dust collection pipes will not interfere with each other, resulting in stable suction power at the dust collection pipe head. Furthermore, the suction power can be flexibly adjusted according to the fabric fiber load in different areas, providing excellent cleaning results.

[0023] Preferably, the dust collection box includes an upper box and a lower box; a filter plate is provided between the upper box and the lower box, the filter plate is used to block fabric fibers from entering the upper box, and the air inlet is located on the side wall of the lower box and below the filter plate.

[0024] Preferably, the upper housing is provided with a number of rubber strips inside, one end of which is fixed to the inner side wall of the upper housing. The rubber strips are hit by the wind to remove dust from the inner wall of the upper housing.

[0025] Preferably, the lower housing sidewall is provided with a number of baffles.

[0026] Preferably, the angle between the baffle plate and the inner side wall of the lower box is 50°-80°.

[0027] Preferably, the dust collection box also includes a differential pressure sensor.

[0028] Preferably, the outer surfaces of the drive box, dust collection box, and three dust collection pipes are all coated with a functional coating.

[0029] The present invention has the following beneficial effects:

[0030] This invention discloses a high-powered vacuum cleaner for cutting tables, which incorporates three dust collection pipes. Each of the three pipes has an independent internal airflow channel, capable of completely covering the bristle area of ​​the cutting table. During the cleaning process, at least one dust collection pipe maintains optimal collection status, ensuring that fabric fibers from all parts of the cutting table are effectively removed, significantly improving cleaning efficiency.

[0031] This invention provides a high-power vacuum cleaner for cutting tables. By independently configuring three dust collection pipes and installing baffles, direct interference between airflows from adjacent integrated pipes is avoided. This ensures uniform negative pressure distribution in each dust collection pipe cavity, guaranteeing that each dust collection pipe head receives a stable and balanced suction, significantly improving overall vacuuming efficiency. Furthermore, when one suction port fails due to blockage, the other ports continue to operate normally without being affected, ensuring stable operation of the vacuum cleaner and improving the reliability of cleaning work.

[0032] The high-power vacuum cleaner for cutting tables of the present invention can flexibly adjust the airflow to the required dust collection pipe by means of valves set on the three dust collection pipes, according to the fabric fiber load in different areas. When the fabric fibers in a certain area are particularly concentrated or a certain dust collection pipe is blocked, the airflow can be concentrated to the required dust collection pipe by closing or reducing the valve opening of other dust collection pipes, thereby enhancing its instantaneous suction power, effectively sucking up the blockage or heavy objects, and improving the cleaning effect.

[0033] This invention discloses a high-power vacuum cleaner for cutting tables. By setting up an upper and lower box, with a filter plate in between, large pieces of fabric fibers and bristles are trapped in the lower box before entering the upper box, thereby reducing the risk of fiber blockage in the upper box. This can extend the service life of the filter plate and filter bag. The rubber strip is beaten by the wind force against the side wall, and it can automatically clean the dust on the inner wall of the box with the airflow without complicated drive, reducing the frequency of manual periodic dust cleaning and reducing maintenance downtime.

[0034] The high-power vacuum cleaner for cutting beds of the present invention has a functional coating on the outer surfaces of the drive box, dust collection box and three dust collection pipes, which reduces surface charge attraction and oil adsorption, making it easier for the bristles to fall off after contact with the shell, reducing bristle adhesion, improving dust removal effect and equipment cleaning efficiency, and extending maintenance intervals. During the dust removal process, the dust attached to the surface can be directly removed by vibration or airflow, improving maintenance efficiency and equipment cleanliness.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example:

[0047] Reference Figures 1 to 5 This invention provides a high-power vacuum cleaner for cutting beds, comprising: a drive box 1, a dust collection box 2, and a plurality of dust collection pipes 3; each dust collection pipe 3 includes a dust collection pipe fixing port 301, a dust collection pipe cavity 302, and a dust collection pipe head 303. The dust collection pipe fixing port 301 is connected to one side of the drive box 1. The drive box 1 is provided with a gas flow channel on the side near the dust collection pipe 3. The dust collection box 2 is provided with an air inlet and an air outlet. The gas flow channel is connected to the air inlet of the dust collection box 2, facilitating the entry of dust and fabric fibers through the dust collection pipe 3, into the interior of the dust collection box 2 through the gas flow channel of the drive box 1, and then the gas is discharged from the air outlet; a motor 4, a fan 5, and a control box 6 are provided on the side of the drive box 1 away from the dust collection pipe 3, and the motor 4 and the fan 5 are connected by a belt.

[0048] The high-power vacuum cleaner for cutting beds provided by this invention preferably has three dust collection pipes 3 in this embodiment. Each dust collection pipe 3 has an independent gas flow channel inside, which can not only completely cover the area of ​​the cutting bed bristles, ensuring that at least one dust collection pipe 3 can maintain the best collection state during the moving cleaning process, thus improving cleaning efficiency, but also avoid multiple suction ports competing for airflow, so that if one suction port fails due to blockage, the other suction ports will also fail. The fan 5 is a vortex negative pressure fan, and the motor 4 drives the fan 5 to operate. The motor generates negative pressure suction in the dust collection pipe 3. The gas carries the dust, fabric fibers, etc. of the bristle layer into one or more dust collection pipe heads 303 of the multiple integrated pipes 3. After passing through the dust collection pipe cavity 302, the gas flow converges after passing through the dust collection pipe fixing port 301, and enters the dust collection box 2 after passing through the drive box 1. The gas is discharged from the air outlet. The dust and fabric fibers are blocked by the dust collection box 2. When the impurities in the dust collection box 2 reach the preset value, the impurities in the dust collection box 2 are removed. The cleaning efficiency is high and the effect is good.

[0049] Furthermore, in another embodiment, the dust collection pipe fixing port 301 is detachably connected to the drive box 1, which facilitates the maintenance or replacement of the dust collection pipe 3. At the same time, dust collection pipes 3 of different sizes or shapes can be replaced to adapt to different application scenarios, increasing the applicability of the equipment. The dust collection box 2 is detachably connected to the drive box 1, and the staff can remove the dust collection box 2 for replacement, which improves work efficiency, maintenance efficiency, and reduces equipment downtime.

[0050] Furthermore, in another embodiment, a handle 101 is provided on one side of the drive box 1, and a roller is installed at the bottom of the drive box 1. The handle 101 is sleeved on the outside of the dust collection box 2, and the roller facilitates dragging the vacuum cleaner, thereby improving the working efficiency of the vacuum cleaner on the cutting bed.

[0051] Reference Figure 6 Furthermore, in another embodiment, the dust collection tube 302 includes a detachable first bend 3021, a second bend 3022 and a third bend 3023, and the head of the dust collection tube 303 is perpendicular to the cutting bed.

[0052] The multiple bends not only guide the airflow path within the dust collection chamber 302, effectively reducing airflow resistance and turbulence during transmission, thus significantly improving dust collection efficiency and reducing energy loss, but also allow for flexible adjustment of the pipe routing according to the actual spatial layout, saving installation space and better adapting to different working environments. The multi-section detachable structure facilitates regular cleaning and maintenance of the dust collection chamber 302 and allows for connection of pipe sections of different lengths as needed. Furthermore, positioning the dust collection pipe head 303 perpendicular to the cutting bed ensures precise alignment with dust and debris generated in the cutting bed's working area. This also allows for more convenient dust collection operations without frequent angle adjustments, achieving more efficient and direct dust collection, preventing dust dispersion, and further improving the equipment's dust removal efficiency.

[0053] Furthermore, in another embodiment, the dust collection tube head 303 is flat and narrow, making it easy to reach into narrow gaps and corners to clean the fibers of the bristle fabric.

[0054] Reference Figure 7 Furthermore, in another embodiment, the dust collection cavity 302 includes a constriction structure, which includes an inlet constriction section 3024, a throat 3025, and an outlet expansion section 3026. One end of the outlet expansion section 3026 is fixedly connected to the drive box 1. When the dust-laden airflow enters the inlet constriction section 3024 of the constriction structure, the flow velocity increases. The increased flow velocity leads to an increase in dynamic pressure, which causes a sharp drop in static pressure at the throat 3025, forming a strong negative pressure area, effectively enhancing the absorption capacity of the stiffened fabric fibers.

[0055] Furthermore, in another embodiment, the dust collection tube head 303 is circular or elliptical, used for cleaning large-area flat surfaces.

[0056] Furthermore, in another embodiment, all three dust collection pipes 3 have a dust collection cavity 302 including a detachable first bend 3021, a second bend 3022, and a third bend 3023, and the dust collection pipe head 303 is flat and narrow. Alternatively, all three dust collection pipes 3 have a dust collection cavity 302 including a necking structure, and the dust collection pipe head 303 is circular or elliptical. Alternatively, one or more dust collection pipes 3 may have a dust collection cavity 302 including a detachable first bend 3021, a second bend 3022, and a third bend 3023, and the dust collection pipe head 303 is flat and narrow. Alternatively, one or more dust collection pipes 3 may have a dust collection cavity 302 including a necking structure, and the dust collection pipe head 303 is circular or elliptical. The flat structure is suitable for cleaning fine areas, while the necking structure is suitable for powerful loosening and anti-clogging tasks. The two structures complement each other and can be intelligently switched according to the actual load, improving system response speed and adaptability. Different structural combinations enhance the overall flexibility and reliability of the system.

[0057] Furthermore, in another embodiment, a baffle 304 is provided between every two adjacent dust collection pipe fixing ports 301. After the baffle 304 is provided, the gas flow converges after passing through the baffle 304 at the end of the dust collection pipe fixing port 301. This not only further avoids direct interference between the airflows of adjacent integrated pipes 3, making the negative pressure distribution of each dust collection pipe cavity 302 uniform, ensuring that each dust collection pipe head 303 can obtain a stable suction force evenly, and improving the overall dust collection efficiency, but also the baffle 304 can suppress the turbulence and oscillation caused by the direct convergence of airflows from different dust collection pipe fixing ports 301, thereby reducing the vibration or filtration obstruction caused by airflow, which helps to form a regular and stable airflow into the dust collection box 2, and improves the stability and working efficiency of filtration.

[0058] Furthermore, in another embodiment, each of the three dust collection ducts 302 is equipped with a valve 305. The valve 305 can be a pneumatic butterfly valve or an electric ball valve. When it is detected that the fabric fibers in a certain area are particularly concentrated and require stronger suction, or when a dust collection duct 3 is blocked, the valves 305 of other dust collection ducts 3 can be closed or reduced by manual intervention or by control box 6. When the valves 305 of two of the dust collection ducts 3 are closed or reduced, almost all the airflow will be concentrated to the only open dust collection duct 3, and the instantaneous suction of the dust collection duct 3 will be greatly enhanced, which is sufficient to pick up the blockage or heavy objects. After completion, control box 6 controls the valve 305 to return to normal.

[0059] Furthermore, in another embodiment, the control box 6 communicates with the CNC system of the cutting bed and controls the opening and closing of the air passage through the valve 305. The system can know in real time which dust collection pipe 3 the cutting knife is currently working around, and briefly close or reduce the airflow of the other two dust collection pipes 3, so that all or most of the power of the fan 5 is concentrated to supply the working dust collection pipe 3, thereby maximizing the suction power and achieving the ultimate dust removal effect and energy saving.

[0060] Furthermore, in another embodiment, the valves 305 provided on the two dust collection chambers 302 are pneumatic butterfly valves, and the valve 305 provided on the third dust collection chamber 302 is an electric ball valve.

[0061] The pneumatic butterfly valve is driven by compressed air, with a fast opening and closing time. It employs a spring-reset structure, automatically returning to a safe position if the air supply is interrupted. Installing pneumatic butterfly valves in the two dust collection chambers 302 enables rapid, reliable, and automatic switching. If a dust collection chamber 302 is blocked by bristles, the pneumatic butterfly valve can immediately close that chamber and reverse direction, quickly releasing suction pressure. The electric ball valve is driven by a motor, providing high precision in controlling valve opening. When a section of a dust collection chamber 302 requires particularly strong suction but does not want to affect other dust collection chambers 302, the suction can be concentrated or balanced by adjusting the electric ball valve opening. The combination of these valves 305 allows the entire dust collection system to quickly and accurately respond to different fabric fiber loads, improving suction switching flexibility, efficiency, and overall reliability.

[0062] Furthermore, in another embodiment, the dust collection tube head 303 is provided with a plurality of guide teeth 3031 for inserting into and separating the bristle layer of the cutting bed.

[0063] The dust collection pipe head 303 is equipped with guide teeth 3031. During the start-up of suction or movement, the guide teeth are inserted into the bristle layer to physically separate the bristle structure, preventing the suction port from being blocked by excessive bristles in an instant, improving the uniformity and stability of airflow, reducing the frequency of blockage, and improving the overall cleaning efficiency and equipment operation reliability.

[0064] Reference Figure 8 Furthermore, in another embodiment, the dust collection box 2 includes an upper box 201 and a lower box 202; a filter plate 203 is provided between the upper box 201 and the lower box 202, the filter plate 203 is used to block fabric fibers from entering the upper box 201, and the air inlet is provided on the side wall of the lower box 201 and the air inlet is located below the filter plate.

[0065] Impurities enter the dust collection box 2 with the airflow. The air inlet is located on the side wall of the lower box 201 and below the filter plate 203. The filter plate 203 can form the first barrier layer between the lower box and the upper box, blocking large pieces of fabric fibers and bristles in the lower box 202 before they enter the upper box 201, thereby reducing the risk of fiber blockage in the upper box 201. When the impurities in the upper box 201 or the lower box 202 reach the preset value, the motor stops running, and the impurities fall due to gravity. The upper box 201 or the lower box 202 is removed to clean the internal impurities and is replaced.

[0066] Furthermore, in another embodiment, the upper housing 201 is provided with a number of rubber strips 204 inside. One end of each rubber strip 204 is fixed to the inner side wall of the upper housing 201. The rubber strips 204 are hit by wind force against the side wall of the upper housing 201 to remove dust from the inner wall of the upper housing 201.

[0067] One end of the rubber strip 204 is fixed to the inner side wall of the upper housing 201. It is beaten by the wind and automatically cleans the dust on the inner wall of the housing as it works with the airflow. No complicated drive is required, reducing the frequency of manual periodic dust cleaning.

[0068] Furthermore, in another embodiment, the lower housing 202 has a plurality of baffles 205 on its sidewall, and the angle between the baffles 205 and the inner sidewall of the lower housing 202 is 50°-80°. In this embodiment, the angle between the baffles 205 and the inner sidewall of the lower housing 202 is preferably 60°. The inhaled gas, carrying fiber debris, circulates throughout the lower housing 202, and the baffles 205 are tilted downward to prevent the flying fiber debris from flowing back upward into the gas flow channel.

[0069] Furthermore, in another embodiment, the dust collection box 2 also includes a differential pressure sensor. The differential pressure sensor is used to monitor the pressure difference inside and outside the dust collection box 2 in real time, and reflects the severity of dust blockage through the pressure difference. When the dust collection box 201 is clogged with bristles and fine dust, the more clogged the dust collection box becomes, the greater the resistance and the higher the pressure difference. When the measured pressure difference is greater than a preset value, the control box 6 automatically activates the dust cleaning component to automatically clean the dust collection box 201, reducing manual intervention.

[0070] Furthermore, in another embodiment, the outer surfaces of the drive box 1, dust collection box 2, and three dust collection pipes 3 are all coated with a functional coating. Preferably, the functional coating of the present invention is an antistatic polyurethane coating. The purpose is to reduce surface charge attraction and oil adsorption, making it easier for the bristles to detach after contact with the outer shell, reducing bristle adhesion, improving dust removal effect and equipment cleaning efficiency, and extending maintenance intervals. During the dust removal process, surface-attached dust can be directly removed by vibration or airflow, improving maintenance efficiency and equipment cleanliness. In the present invention, the functional coating is formed by applying an antistatic composite coating, mainly using graphene oxide (GO) as a carrier, with silver particles adhering to and uniformly dispersed on its surface. In addition, polyetheramine modifies the edge carboxyl groups of the GO carrier to prepare an antistatic composite material. Finally, the antistatic composite material is mixed into water-based polyurethane and coated onto the surface of the target object, ultimately forming a functional coating with excellent antistatic properties, which helps reduce bristle adhesion and improve dust removal effect and equipment cleaning efficiency. The preparation of the antistatic composite coating includes three steps: preparation of silver-modified GO, preparation of modified composite material, and preparation of composite coating. The specific preparation steps are as follows:

[0071] S1, Preparation of Silver-Modified GO

[0072] GO was placed in PBS buffer and ultrasonically stirred for 1.5-2.5 hours to form a uniform GO dispersion of 0.25-0.50 mg / mL. Then, it was magnetically stirred in a multi-functional heated stirrer at a speed of 270-330 rpm. While stirring, a 0.05-0.08 M silver nitrate solution was added dropwise. The mixture was then heated to 80°C, and a reducing agent was added to reduce the silver nitrate to silver particles, which adhered to the wrinkled surface of the GO, resulting in a preliminary mixed liquid. After the addition was complete, stirring continued for 6-8 hours. The reducing agent was hydrazine hydrate or glucose solution, and the theoretically calculated mass ratio of reduced silver to GO was (1-1.5):40. Furthermore, the GO was industrial grade and purchased from Nanjing Xianfeng Nanomaterials.

[0073] Preferably, in this invention, the concentration of the GO dispersion is 0.35 mg / mL, the concentration of the silver nitrate solution is 0.07 M, and the mass ratio of silver to GO is 1:40;

[0074] S2, Preparation of Modified Composite Materials

[0075] In step S1 above, polyetheramine is added to the initially mixed liquid. After sufficient reaction, the mixture is allowed to stand, centrifuged, and washed until the supernatant is neutral. The supernatant is removed, and the mixture is re-dispersed in deionized water by ultrasonication to obtain a modified dispersion. The mass ratio of polyetheramine to GO is (9.1-9.6):1.

[0076] A 1M solution of 2-acrylamido-2-methylpropanesulfonic acid was prepared and divided into two portions, designated as Solution 1 and Solution 2. Aniline was added to Solution 1, and ammonium persulfate was added to Solution 2, with a molar ratio of aniline to ammonium persulfate of 0.7:1. Solutions 1 and 2 were then placed in an ice-water bath for homogeneous mixing. After homogeneous mixing, the modified dispersion was added to Solution 1 and stirred at the same stirring rate to form a multi-stage mixed liquid. The homogeneous second solution was then added dropwise to the multi-stage mixed liquid at a dropping rate of 0.5 mL / min. After the addition was complete, the mixture was kept in an ice-water bath for homogeneous mixing for 3-5 hours, and then allowed to stand at room temperature for 24-36 hours. The resulting product was demulsified with acetone and stirred, then washed with ethanol and deionized water until neutral. After freeze-drying, the modified composite material was obtained.

[0077] Among them, the 2-acrylamido-2-methylpropanesulfonic acid solution is a doped acid system, which is beneficial for the preparation of composite materials.

[0078] S3, Preparation of Composite Coatings

[0079] Based on waterborne polyurethane as the weight component, 1%-3% of the modified composite material prepared by S2 above is ultrasonically dispersed in water to prepare an aqueous dispersion, which is then mixed with the waterborne polyurethane. The mixture is then emulsified into a homogeneous emulsion under high-speed stirring to form a composite coating with antistatic properties.

[0080] Polyaniline was composited with silver-modified GO to prepare a polyaniline / AGO coating with high conductivity and good performance, effectively improving the dispersibility of the composite material. Furthermore, the addition of polyetheramine forms a network-like electrostatic conductive structure, further enhancing the dispersibility and compatibility of silver-modified GO in aqueous systems. Moreover, the silver particles on the GO surface can fill the gaps in the network structure, providing antistatic properties. Polyaniline molecules are uniformly attached to the GO surface through electrostatic interactions, and the conductivity is further improved through doping technology. Testing showed that the surface resistivity of the waterborne polyurethane coating with the modified composite material reached 3.21 × 10⁻⁶. 8 With an adhesion rating of 0, a pencil hardness of 5H, and a corrosion potential of -0.446mV, this coating exhibits good antistatic properties, excellent adhesion, and corrosion resistance.

[0081] Working principle:

[0082] When the high-power vacuum cleaner is working on this cutting table, the motor 5 in the drive box 1 starts under the control of the control box 6. The motor 4 drives the fan 5 to rotate via a belt. Since the fan 5 is a vortex negative pressure fan, the motor 4 drives the fan 5 to rotate, which will generate negative pressure suction in the dust collection pipe 3. Under the action of negative pressure suction, the debris, dust, and fabric fibers on the cutting table enter the dust collection pipe cavity 302 from one or more dust collection pipe heads 301 in the dust collection pipe 3. Then, after passing through the dust collection pipe fixing port 303, they converge into the gas channel in the drive box 1, and then enter the dust collection box 2 through the drive box 1. The fabric fibers are finally trapped in the dust collection box, while the filtered clean gas is discharged from the vacuum cleaner. When the fabric fibers in the dust collection box 2 accumulate to the preset value, the operator can remove the dust collection box 2 from the drive box 1 and replace it with a new dust collection box 2 to ensure the continuous and efficient operation of the vacuum cleaner. Throughout the process, the control box 1 will intelligently allocate the power of the motor 4 according to the actual load to achieve the purpose of energy saving and efficient cleaning.

[0083] Because the head of the dust collection pipe 303 is perpendicular to the cutting bed and is flat and narrow, it can accurately target the dust and debris generated in the working area of ​​the cutting bed. In particular, it can reach into narrow gaps and corners to effectively suck up the fabric fibers. The sucked-up fabric fibers enter the dust collection pipe cavity 302 with the airflow. The dust collection pipe cavity 302, which has multiple bends, guides the airflow to flow along a preset path, reducing the resistance and turbulence of the airflow during transmission, so that the airflow can flow more smoothly. The airflow carries the fabric fibers through each bend and arrives at the dust collection box.
