Description

Technical Field

[0001] The invention relates to the technical field of Pilates fitness equipment processing equipment, in particular to a special grinding equipment for Pilates bed accessories with the function of separating and collecting ferrous metal dust. Background Art

[0002] With the popularity of Pilates, the manufacturing and processing of its core equipment, the Pilates bed, has also received more and more attention. During the grinding and polishing process of the metal accessories of the iron Pilates bed, a large amount of high-speed flying iron-containing metal dust will be generated. This dust will not only adhere to the surface of the equipment and workpiece, affecting the processing quality, but may also be inhaled by the operator, causing health hazards. At the same time, the mixing of metal dust with abrasive particles and resin particles shed from the grinding wheel also increases the difficulty of recycling and reusing metal dust.

[0003] In the prior art, for example, the patent with publication number CN118903998A discloses an efficient industrial dust treatment device, which uses a pump to atomize water to humidify and reduce dust, and sets an elastic filter cloth to drive the dust floating on the water surface to sink. However, this water-washing dust reduction method has obvious shortcomings: first, the high-speed flying metal dust is difficult to be effectively controlled by water mist in the initial stage and is easy to splash everywhere; second, the water washing process will further mix the metal dust with other impurities, increasing the difficulty of subsequent separation; in addition, this solution requires continuous water supply and generates a large amount of wastewater, which has high equipment maintenance costs and is not conducive to environmental protection.

[0004] Therefore, a special grinding equipment is needed that can effectively control and multi-stage separate ferrous metal dust, extend the dust movement path through reasonable structural design, and use multiple effects such as gravity sedimentation and magnetic adsorption to achieve directional collection and resource utilization of dust. Summary of the invention

[0010] Preferably, the penetration plate of the first isolation component adopts an inner and outer double-layer composite honeycomb mesh structure, which is arranged in an arched shape as a whole and forms an inclined angle with the horizontal plane.

DETAILED DESCRIPTION

[0016] The following will be combined Figure 1-Figure 8 The preferred embodiments of the present invention are described in detail. It should be noted that the following description is only a preferred embodiment of the present invention, rather than a limitation of the present invention. Those skilled in the art should understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the attached claims.

[0017] Example 1 A special grinding device for Pilates bed accessories with metal dust separation and collection function This embodiment provides a grinding device that can achieve graded separation and efficient collection of metal dust. By innovatively designing a multi-stage separation and collection system including penetration diversion, magnetic adsorption, and filtration purification, a large amount of metal dust, abrasive particles, resin particles and other mixed substances that were originally generated in a concentrated manner are dispersed into multiple processing lines. By extending the dust movement path and setting multiple collection points, the orderly diversion and step-by-step processing of metal dust are achieved, so that the metal dust generated during the processing of Pilates bed accessories can be efficiently and directional collected and resourced. The following is a grinding and polishing of the metal (iron) accessory side panel of the Pilates bed 01 (such as Figure 1 ) as an example for explanation.

[0018] refer to Figure 2-Figure 4The special grinding equipment mainly includes: a frame 10, wherein the frame 10 has a grinding area 02 and a dust collection area 03 connected to each other. The grinding area 02 is provided with a workbench 20 that can move along the XY horizontal plane direction, and the workbench 20 is provided with a grinding fixture 30 for batch processing. The grinding fixture 30 adopts a quick clamp structure and can simultaneously install and fix multiple side panels 01 to be processed. The grinding area 02 also includes a horizontally arranged cylindrical grinding wheel 40 arranged directly above the grinding fixture 30, and a dust multi-stage separation device 50 arranged in the dust collection area 03.

[0019] The dust collection area 03 is completely isolated from the external environment by the sealing structure of the frame 10, and has good sealing and dustproof effects. Specifically, the dust collection area 03 is sequentially provided with three functional areas along the dust treatment direction: the first treatment area 04 adopts the principle of gravity sedimentation and combines the directional flow guide design to achieve preliminary diversion and separation of high-speed flying dust; the second treatment area 05 adopts magnetic adsorption technology combined with variable cross-section adsorption design to grade metal dust of different particle sizes; the third treatment area 06 adopts a filter vibration device to finally collect the residual dust that failed to be captured in the first two stages, thereby forming a complete graded treatment system.

[0020] refer to Figure 4-Figure 7 The multi-stage dust separation device 50 adopts an innovative design of partition isolation and graded collection, and mainly includes: a first isolation component 51 arranged between the first processing area 04 and the second processing area 05, which is used to realize the initial diversion of dust; a second isolation component 52 arranged between the second processing area 05 and the third processing area 06, which is used to realize the magnetic adsorption of metal dust; a dust suction pipe 53 running through the first processing area 04 and the second processing area 05, which is used for filtering and collecting fine particles; and a dust scraping structure 54 arranged at the far end of the third processing area 06, which is used to realize the cleaning and recovery of magnetically adsorbed dust.

[0021] The first isolation component 51 is specially designed, with a penetration plate 511 composed of metal or high-strength nylon thin lines arranged at equal intervals, and equipped with a first guide plate 512 and a second guide plate 513, forming a complete diversion system. The dust collection duct 53 adopts a multi-layer filter cotton structure arranged obliquely. The first coarse filter layer is used to intercept abrasive particles, the medium and fine filter layer is responsible for intercepting resin particles, and the last ultra-fine filter layer can effectively absorb PM2.5 and other fine particles that are harmful to the human body. At the same time, through the variable cross-section design, different adsorption forces are formed in the first treatment area 04 and the second treatment area 05 (the adsorption force of the first treatment area 04 is greater than that of the second treatment area 05), so that fine particles are adsorbed into the filtration system, while larger particles naturally settle in the weaker adsorption area to the second treatment area 05. This differentiated adsorption force design not only ensures the efficient filtration of fine particles such as PM2.5, but also avoids the clogging of filter cotton by larger particles, thereby improving the overall graded filtration efficiency. The core component of the second treatment area 05 is the magnetic adsorption cylinder 521 driven by the drive motor 522, which is made of high-performance rare earth permanent magnet material. A gap of a specific width is precisely designed between the second processing area 05 and the third processing area 06, and a unique composite guide structure is formed by the third guide plate 523 and the arc-shaped guide plate 524.

[0022] The specific working process is as follows: First, multiple side plates 01 are installed and fixed on the grinding fixture 30 through a quick clamp. After starting the equipment, the cylindrical grinding wheel 40 rotates at high speed under the drive of the servo motor to grind the multiple side plates 01 at the same time. During the grinding process, since the rotation direction of the cylindrical grinding wheel 40 is specifically set toward the dust collection area 03, and multiple side plates 01 are ground in batches at the same time, a large amount of high-speed moving metal dust will be generated, accompanied by abrasive particles and resin particles falling off the surface of the cylindrical grinding wheel 40. These substances of different properties will be mixed under the action of airflow and concentratedly transported from the grinding area 02 to the dust collection area 03 for classification and treatment. Since the density of abrasive particles and resin particles is significantly different from that of metal dust, metal dust with relatively large particle size will be thrown farther under the action of gravity, and it is easier to pass through the penetration plate 511 of the first processing area 04 and be directly adsorbed by the magnetic adsorption cylinder 521 at the corresponding position. Metal dust, abrasive particles and resin particles with relatively small particle sizes are more easily taken away by the second guide plate 513 and enter the dust collection duct 53 in an orderly manner. After passing through the multi-layer filtration structure arranged obliquely in the dust collection duct 53, the abrasive particles are intercepted by the first coarse filter layer, and the resin particles are effectively intercepted in the medium and fine filter layer. Larger particles of metal dust naturally settle to the second treatment area 05 through the variable cross-section design. The magnetic adsorption cylinder 521 achieves efficient dynamic adsorption of metal dust by continuous uniform rotation, and the unadsorbed dust flows in a directional manner to the third treatment area 06 through specific gaps and composite guide structures. This natural diversion method based on the difference in material density not only simplifies the collection structure, but also improves the separation efficiency.

[0023] When a grinding process is completed and the loading and unloading needs to be stopped, the system will start the screw structure 55 to drive the magnetic adsorption cylinder 521 to move accurately to the dust scraping structure 54 for cleaning. At this time, the metal dust adsorbed on the surface of the magnetic adsorption cylinder 521 will be effectively scraped off by the fixed scraping plate 541 into the storage tank 542 below, realizing the centralized collection of dust. This design not only ensures the efficient separation and recovery of metal dust, but also does not affect the normal operation efficiency of the equipment through reasonable coordination with the production rhythm. Through this multi-stage linkage separation design, the equipment successfully realizes the graded treatment, directional collection and resource utilization of metal dust generated during the grinding process.

[0024] It should be noted that the screw structure 55 drives the magnetic adsorption cylinder 521 to perform dust cleaning during the grinding process pause and the switching of loading and unloading. This time arrangement has the following advantages: no new dust is generated in the grinding area 02, which is conducive to the magnetic adsorption cylinder 521 to absorb the deposited dust to the maximum extent when passing through the third processing area 06; improves the overall dust collection efficiency; does not affect the normal production rhythm; and facilitates the subsequent classification, collection and treatment of dust.

[0025] In order to solve the diffusion problem and low adsorption efficiency caused by the high-speed dispersion of metal dust, this embodiment has innovatively designed the first isolation component 51. The specific structure and working principle are as follows: the core component of the first isolation component 51 is the penetration plate 511, which is composed of multiple thin wires made of metal or high-strength nylon arranged at equal intervals. The material selection and spacing design of the thin wires must meet the following requirements: they have sufficient mechanical strength to withstand the impact of high-speed metal dust; the spacing must be moderate to ensure that the metal dust can pass smoothly and play a preliminary diversion role; the arrangement direction of the thin wires must be adapted to the movement trajectory of the dust. Through this multi-stage separation design, the equipment can achieve efficient separation and collection of metal dust, while ensuring the cleanliness of the working environment and the health and safety of the operators.

[0026] In order to further improve the dust separation efficiency, this embodiment systematically optimizes the guide and filtration system: a double guide plate structure is integrated in the first isolation component 51, the first guide plate 512 extends from the lower end of the penetration plate 511 to the junction of the grinding area 02 and the dust collection area 03, and the second guide plate 513 extends from the upper end of the penetration plate 511 and is arranged around the air inlet area of ​​the dust suction pipe 53 (keeping a gap with the air inlet in height, and completely covering the trajectory range of the dust falling from the air inlet in the horizontal range), forming two upper and lower directional channels. At the same time, the filter cotton in the dust suction pipe 53 is arranged in an inclined manner to ensure that the inclination direction is consistent with the dust flow. Through this structural design, fine particles are sucked into the dust suction pipe 53 and effectively intercepted by the filter cotton, while larger particles naturally slide down from the inclined filter cotton surface under the action of gravity and are orderly guided to the second processing area 05 by the second guide plate 513, realizing efficient graded collection of dust.

[0027] In order to maximize the adsorption efficiency of metal dust, the second isolation component 52 is designed with a unique composite guide structure: the third guide plate 523 extends from the bottom of the dust collection pipe 53 to the position of the magnetic adsorption cylinder 521, and the arc guide plate 524 is coaxially designed with the magnetic adsorption cylinder 521 and bridges the penetration plate 511 and the third processing area 06. By reserving a precise gap between the arc guide plate 524 and the magnetic adsorption cylinder 521, a directional flow channel is provided for the dust to flow to the third processing area 06 while ensuring the degree of rotation freedom. This innovative composite guide structure not only improves the directional transportation and capture efficiency of dust, but also realizes graded separation, effectively ensuring the continuous and stable operation of the entire system.

[0028] In view of the technical problems existing during the operation of the magnetic adsorption cylinder 521, especially the gap between it and the third processing area 06 which may lead to insufficient dust collection, and the increase in the connecting space between the second and third processing areas during the movement which may cause secondary dust sedimentation, this embodiment solves these problems through the innovative design of the filter vibration structure.

[0029] refer to Figure 6-Figure 7In this embodiment, a filter screen 56 with a special mesh structure is arranged in the third processing area 06, and it is installed between the arc guide plate 524 and the fixed scraper plate 541 to collect the residual metal dust that is not adsorbed by the magnetic adsorption cylinder 521. At the same time, the installation method of the fixed scraper plate 541 is innovatively designed: a hinged connection is formed with the frame 10 through a hinge shaft, and a torsion spring is set on the outer wall of the hinge shaft, so that the fixed scraper plate 541 has a controllable elastic rotation function. In terms of structural space arrangement, the installation position and angle of the fixed scraper plate 541 are determined by calculation, so that the end away from the filter screen 56 and the magnetic adsorption cylinder 521 produce a preset mechanical interference, and when the magnetic adsorption cylinder 521 rotates, the fixed scraper plate 541 can be periodically pressed down. The reciprocating springing of the fixed scraper plate 541 under the action of the torsion spring drives the filter screen 56 to vibrate continuously up and down, thereby effectively shaking off the metal dust attached to the surface of the filter screen 56, and significantly improving the dust collection efficiency.

[0030] Working principle: It mainly focuses on three aspects: the vibration cleaning mechanism of the magnetic adsorption cylinder 521, the mechanical structure design of the grinding system, and the overall workflow.

[0031] 1. Filter vibration cleaning structure design When the magnetic adsorption cylinder 521 is in operation, the dust collection problem is solved through an innovative vibration cleaning mechanism: when it rotates counterclockwise to the fixed scraper plate 541, the fixed scraper plate 541 is pressed down through mechanical interference, and reciprocating springs are generated under the action of the torsion spring, driving the filter 56 to vibrate periodically. This simple and reliable structure that does not require an additional power source can optimize the vibration frequency through the torsion spring parameters and continue until the dust is completely removed. In order to further improve the cleaning efficiency, a two-way scraping mechanism is designed, which realizes precise reciprocating motion through a power mechanism composed of a movable scraper plate 543 made of wear-resistant alloy and a precision scraper motor to ensure thorough cleaning.

[0032] 2. Mechanical system integrated design Grinding power system: includes a high-efficiency drive motor with variable frequency speed regulation, a synchronous pulley assembly and a transmission belt, all of which are installed on the reinforced support structure of the frame 10 to reduce vibration.

[0033] Height adjustment mechanism: The cylindrical grinding wheel 40 is precisely positioned through a first connecting block 421 hinged by a pin, a second connecting block 422 hinged by a self-lubricating bearing, and a lifting mechanism composed of a ball screw 423 and a rotating handle 424 for easy operation.

[0034] Bidirectional moving mechanism: The tangential movement adopts hydraulically driven slide rails, and the axial movement is achieved by servo motor 821 and eccentric wheel group to ensure grinding accuracy.

[0035] 3. Automated Workflow Grinding stage: After the multiple side plates 01 are installed at the same time, all-round grinding is carried out under the cooperation of the tangential and axial moving mechanisms. The generated metal dust is diverted through the penetration plate 511, part of which is directly adsorbed by the magnetic adsorption cylinder 521, and part of which enters the dust collection pipe 53 through the guide plate. The dust is graded through the filter cotton, and the large particles are guided to the magnetic adsorption cylinder 521 through the third guide plate 523, and the rest flows to the filter screen 56 along the arc guide plate 524.

[0036] Cleaning stage: When grinding stops and material change begins, the screw structure 55 drives the magnetic adsorption cylinder 521 to move, and achieves the adsorption of metal dust in the dust on the surface of the filter 56. When it reaches the position of the fixed scraper plate 541, it not only scrapes the surface dust but also drives the filter to vibrate and clean. When the adsorption amount is large, the movable scraper plate 543 is started for reverse coordination cleaning.

[0037] Recycling: After the cleaned dust accumulates to a set amount in the storage tank 542, it is transported to the dust treatment device 70 through the sealed pipe 60. The device realizes environmental protection treatment and resource recovery of dust through the sealed box 71, adsorption power component 72 and water washing system.

[0038] Through the coordinated operation of the above systems, the entire process from grinding to dust recovery is automated, significantly improving the cleanliness and environmental protection level of Pilates bed accessory processing.

[0039] Example 2 Reference Figure 8 Based on Example 1, this embodiment mainly improves and innovates the structure of the penetration plate 511 of the first isolation component 51. The basic layout of the grinding area 02 and the dust collection area 03 in Example 1, as well as the arrangement of core components such as the magnetic adsorption cylinder 521 and the dust collection pipe 53 are maintained.

[0040] The innovation lies in the fact that the penetration plate 511 adopts a design of an inner and outer double-layer honeycomb unit composite structure. The whole is set in an arch shape, forming an inclination angle of 15-20° with the horizontal plane.

[0041] The inner mesh (close to the grinding area) adopts a small-sized honeycomb unit design (side length 6-8mm) with dense but equal spacing, and 2-3 layers of deep corrugations (peak height 3-4mm) are formed on the inner surface, with a small mesh diameter (0.8-1.0mm). This structural design can provide stronger deformation buffering ability and achieve precise filtration.

[0042] The outer mesh adopts a large-sized honeycomb unit design (side length 15-18mm) corresponding to the number and position of the small-sized honeycomb units, and forms 5-6 layers of shallow corrugations (peak height 1.5-2mm) on the inner circumference, with a large mesh diameter (1.2-1.5mm). The outer mesh is evenly distributed radially on the arch surface, and the central axis of each large-sized honeycomb unit points to the focus of the arch. In order to improve the separation effect, the outer honeycomb units are staggered with the inner layer, so that the upper boundary of the outer unit coincides with the upper boundary of the inner unit.

[0043] There is a gap between the two layers of mesh, which forms a cavity with a variable cross-section. The time interval is 3mm near the inner side of the arch, and gradually increases to 5mm outward. When dust passes through, the small-sized honeycomb unit and the large-sized honeycomb unit simultaneously produce vibration and buffering effects. Part of the dust changes its movement trajectory in the cavity with a variable cross-section under the resonance of the two layers of mesh. Through the cooperation of the corrugated structure of the inner and outer layers of mesh and the cavity with a variable cross-section, multiple diversions and filtration are formed. This structure not only extends the movement path of the dust, but the independent vibration and resonance of the two layers of mesh can also produce eddy current effects to enhance the separation effect. In addition, based on the flexible characteristics of the mesh material, the outer surface of the arch structure produces high-frequency and violent structural oscillations under the continuous impact of dust. This oscillation forms a strong dynamic collision with the naturally falling dust in the second processing area 05, which not only changes the movement trajectory of the dust, but also makes the dust form a discrete state in space, greatly increasing the contact opportunity between the dust and the magnetic adsorption cylinder 521, thereby improving the capture efficiency of the dust.

[0044] The double-layer composite structure of this embodiment achieves efficient dust absorption and caching through clever design. The inner and outer layers of mesh work synchronously, and the positions of the outer large-size honeycomb units and the inner small-size honeycomb units correspond one to one. Their upper boundaries overlap and are set on the arched surface and radially point to the focus to form a continuous filtering channel. The design of the arched surface allows the dust to flow downward naturally when entering, and the radial arrangement pointing to the focus allows each honeycomb unit to receive the incoming flow at the optimal angle. The upper space of the large-size honeycomb unit forms a natural receiving cavity, which can better accommodate and buffer the initial high-speed dust flow. When the dust enters, it passes through the corrugated structure of the outer and inner layers at the same time. The corrugations and meshes of different sizes provide multi-layer buffering and filtering effects, effectively reducing dust rebound. The variable cross-section cavity between the two layers gradually expands from the inside to the outside, so that the dust forms a spiral motion trajectory when passing through, which significantly prolongs the dust's residence time in the system. In addition, the independent vibration and resonance effects of the two layers of mesh form a stable eddy current field in the cavity, further prolonging the dust movement path and enhancing the absorption effect. In particular, each honeycomb unit forms an independent storage space that can temporarily store incompletely filtered dust, while the overflowing dust will naturally fall into the honeycomb unit below to continue to be captured, forming a multi-level cache and circulation filtration system. This structural design not only allows the dust to undergo multiple filtration and absorption processes through natural forces, but also provides sufficient cache space to ensure that the dust is captured step by step, minimizing the probability of dust rebound and escape.

[0045] The overall frame of this embodiment is made of lightweight aluminum alloy profiles bent into an arch shape, and precision processing is used to ensure that the guide grooves inside and outside the profile maintain concentric arcs. The frame is designed with a quick disassembly and assembly mechanism to facilitate daily cleaning and maintenance while ensuring sealing. The protective cover around the frame adopts a progressive contraction design that matches the curvature of the arched surface, which not only avoids dust spillage, but also enhances the airflow guidance effect.

[0046] The above description is only a specific example and does not constitute any limitation to the present invention. Obviously, after understanding the content and principle of the present invention, professionals in this field may make various modifications and changes in form and details without departing from the principle and structure of the present invention, but these modifications and changes based on the idea of ​​the present invention are still within the scope of protection of the claims of the present invention.
