Description

Technical Field

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

[0002] With the popularization of Pilates exercise, the manufacturing and processing of its core equipment, the Pilates bed, have received increasing attention. During the grinding and polishing process of iron Pilates bed metal accessories, a large amount of high-speed flying iron-containing metal dust will be generated. These dusts will not only adhere to the surfaces of equipment and workpieces, affecting the processing quality, but may also be inhaled by operators, posing a health hazard. At the same time, due to the mixing of metal dust with abrasive grains and resin grains falling off the grinding wheel, it also increases the difficulty of recycling and reusing metal dust.

[0003] In the prior art, a patent with the publication number CN118903998A discloses an industrial dust efficient treatment equipment, which atomizes water through a pump 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 deficiencies: First, it is difficult for the high-speed flying metal dust to be effectively controlled by water mist in the initial stage and is prone to splashing everywhere; Second, the water washing process will further mix the metal dust with other impurities, increasing the subsequent separation difficulty; In addition, this solution requires continuous water supply and generates a large amount of wastewater, with high equipment maintenance costs and is not conducive to environmental protection.

[0004] Therefore, a special grinding equipment capable of effectively controlling and multi-stage separating iron-containing metal dust is needed. By a reasonable structural design, the movement path of the dust is extended, and the directional collection and resource utilization of the dust are realized through multiple actions such as gravitational sedimentation and magnetic adsorption. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies of the prior art and provide a special grinding equipment for Pilates bed accessories with the function of separating and collecting metal dust.

[0013] A dust suction pipe, penetrating through the first treatment area and the second treatment area, and an inclined filter cotton structure is arranged inside the dust suction pipe;

[0014] The second isolation component is arranged between the second processing area and the third processing area and is used to achieve magnetic adsorption of metal dust. The second isolation component specifically includes: a) a magnetic adsorption cylinder driven by a driving motor; b) a third diversion plate extending from below the dust suction pipe to the position of the magnetic adsorption cylinder; c) an arc-shaped diversion plate coaxially designed with the magnetic adsorption cylinder and spanning the penetration plate and the third processing area; d) a gap is reserved in the second isolation component to ensure the rotational freedom of the magnetic adsorption cylinder and provide a directional flow channel for the dust.

[0015] The dust scraping structure is arranged at the far end of the third processing area and is used to achieve the cleaning and recovery of magnetically adsorbed dust.

[0016] Beneficial effects: The specific structures and functions of each processing area are refined. The first isolation component realizes preliminary diversion, the dust suction pipe and the second isolation component form a magnetic adsorption system, and the dust scraping structure completes the final cleaning.

[0017] Preferably, the penetration plate of the first isolation component adopts an inner and outer double-layer composite honeycomb mesh structure, which is integrally arched and forms an inclined angle with the horizontal plane. Preferably, the inner and outer double-layer composite honeycomb mesh structure includes: an inner layer mesh, close to the grinding area, which adopts small-sized honeycomb units with a dense but equal spacing, and multiple layers of deep corrugations are formed on the inner peripheral surface; an outer layer mesh, which adopts large-sized honeycomb units corresponding to the number and position of the inner layer units, and multiple layers of shallow corrugations are formed on the inner peripheral surface.

[0032] Embodiment 1 A special grinding device for Pilates bed accessories with metal dust separation and collection function

[0033] This embodiment provides a grinding device capable of realizing hierarchical separation and efficient collection of metal dust. By innovatively designing a multi-stage separation and collection system including penetration and diversion, magnetic adsorption, and filtration and purification, a large amount of mixed substances such as metal dust, abrasive grains, and resin grains originally generated concentrated are dispersed into multiple treatment lines. By extending the dust movement path and setting multiple collection points, the orderly diversion and step-by-step treatment of metal dust are realized, so that the metal dust generated in the processing of Pilates bed accessories can be efficiently and directionally collected and resourcefully treated. The following takes the side plate 01 of the metal (iron) accessory of the Pilates bed (as Figure 1 shown) as an example for illustration.

[0034] Refer to Figures 2-4, The dedicated grinding equipment mainly includes: a frame body 10, and an interconnected grinding area 02 and a dust collection area 03 are formed inside the frame body 10. Among them, a workbench 20 that can move in the X-Y horizontal plane direction is arranged in the grinding area 02. A grinding jig 30 for batch processing is provided on the workbench 20. The grinding jig 30 adopts a quick fixture structure and can simultaneously install and fix a plurality of side plates 01 to be processed. The grinding area 02 further includes a horizontally arranged cylindrical grinding wheel 40 disposed directly above the grinding jig 30, and a multi-stage dust separation device 50 disposed in the dust collection area 03.

[0035] The dust collection area 03 is completely isolated from the external environment through the sealing structure of the frame body 10, and has good sealing performance and dust prevention effect. Specifically, three functional areas are sequentially arranged in the dust collection area 03 along the dust treatment direction: the first treatment area 04 adopts the principle of gravity sedimentation and combines with the directional diversion design to achieve preliminary diversion and separation of the rapidly scattered dust; the second treatment area 05 adopts magnetic adsorption technology and combines with the variable cross-section adsorption design to classify and collect metal dust of different particle sizes; the third treatment area 06 adopts a filter screen vibration device to finally collect the residual dust that cannot be captured by the first two stages, thus forming a complete classification treatment system.

[0036] Reference Figures 4-7 , The multi-stage dust separation device 50 adopts an innovative design of partition isolation and hierarchical collection, and mainly includes: a first isolation component 51 arranged between the first treatment area 04 and the second treatment area 05, which is used to achieve the first diversion of dust; a second isolation component 52 arranged between the second treatment area 05 and the third treatment area 06, which is used to achieve the magnetic adsorption of metal dust; a dust suction pipe 53 that penetrates through the first treatment area 04 and the second treatment area 05, which is used for the filtration and collection of fine particles; and a dust scraping structure 54 arranged at the far end of the third treatment area 06, which is used to achieve the cleaning and recycling of magnetically adsorbed dust.

[0037] 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.

[0038] 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.

[0039] When the grinding of a process needs to pause the loading and unloading, the system will start the lead screw structure 55, driving the magnetic adsorption cylinder 521 to move precisely 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 recycling of metal dust, but also, through reasonable coordination with the production rhythm, does not affect the normal operation efficiency of the equipment. Through this multi-stage linkage separation design, the equipment has successfully achieved the classification treatment, directional collection and resource utilization of the metal dust generated during the grinding process.

[0040] It should be particularly noted that the lead screw structure 55 drives the magnetic adsorption cylinder 521 to perform the dust cleaning operation during the pause of the grinding process and the switching of loading and unloading. This timing arrangement has the following advantages: no new dust is generated in the grinding area 02, which is conducive to the magnetic adsorption cylinder 521 maximizing the adsorption of deposited dust when passing through the third treatment area 06; improving the overall dust collection efficiency; not affecting the normal production rhythm; facilitating the subsequent classification collection and treatment of dust.

[0041] To solve the problems of diffusion caused by the high-speed scattering of metal dust and low adsorption efficiency, this embodiment has made an innovative design for 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 lines made of metal or high-strength nylon arranged at equal intervals. The material selection and spacing design of the thin lines need to meet the following requirements: having sufficient mechanical strength to withstand the impact of high-speed metal dust; the spacing should be moderate, ensuring that the metal dust can pass through smoothly while playing a preliminary guiding role; the arrangement direction of the thin lines should be adapted to the dust movement trajectory. Through this multi-stage separation design, the equipment can achieve the efficient separation and collection of metal dust, while ensuring the cleanliness of the working environment and the health and safety of operators.

[0042] To further improve the dust separation efficiency, the diversion and filtration system is systematically optimized in this embodiment: a double-diversion plate structure is integrated in the first isolation component 51. The first diversion 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, while the second diversion 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 (maintaining a gap in height with the air inlet and completely covering the trajectory range of the falling dust from the air inlet within the horizontal range), forming two upward and downward 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 inclined 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 surface of the filter cotton under the action of gravity and are orderly guided by the second diversion plate 513 to the second treatment area 05, achieving efficient classification and collection of dust.

[0043] To maximize the adsorption efficiency of metal dust, the second isolation component 52 is designed with a unique composite diversion structure: the third diversion plate 523 extends from below the dust suction pipe 53 to the position of the magnetic adsorption cylinder 521, and the arc-shaped diversion plate 524 is coaxially designed with the magnetic adsorption cylinder 521 and spans the penetration plate 511 and the third treatment area 06. By leaving a precise gap between the arc-shaped diversion plate 524 and the magnetic adsorption cylinder 521, while ensuring the rotational freedom, a directional flow channel for dust to the third treatment area 06 is provided. This innovative composite diversion structure not only improves the directional transportation and capture efficiency of dust but also realizes classification separation, effectively ensuring the continuous and stable operation of the entire system.

[0044] Aiming at the technical problems existing in the operation of the magnetic adsorption cylinder 521, especially the problem that the gap between it and the third treatment area 06 may lead to insufficient dust collection, and the problem of secondary dust settlement caused by the increase in the connected space between the second and third treatment areas during movement, this embodiment is solved by innovatively designing a filter screen vibration structure.

[0045] Reference Figures 6-7, In this embodiment, a filter screen 56 with a special mesh structure is arranged in the third processing area 06 and is installed across between the arc-shaped guide plate 524 and the fixed scraping plate 541 for collecting residual metal dust that has not been adsorbed by the magnetic adsorption cylinder 521. At the same time, the installation method of the fixed scraping plate 541 is innovatively designed: it is hinged to the frame body 10 through a hinge shaft, and a torsion spring is sleeved on the outer wall of the hinge shaft, so that the fixed scraping plate 541 has a controllable elastic rotation function. In terms of structural space layout, the installation position and angle of the fixed scraping plate 541 are determined through calculation, so that one end of the fixed scraping plate 541 away from the filter screen 56 has a preset mechanical interference with the magnetic adsorption cylinder 521, and when the magnetic adsorption cylinder 521 rotates, it can periodically press down the fixed scraping plate 541. The reciprocating elastic movement of the fixed scraping plate 541 under the action of the torsion spring drives the filter screen 56 to vibrate continuously up and down, thus effectively shaking off the metal dust attached to the surface of the filter screen 56 and significantly improving the dust collection efficiency.

[0046] Working principle:

[0047] 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 working process.

[0048] I. Design of the filter screen vibration cleaning structure

[0049] When the magnetic adsorption cylinder 521 is running, the dust collection problem is solved through an innovative vibration cleaning mechanism: when it rotates counterclockwise to the fixed scraping plate 541, it presses down the fixed scraping plate 541 through mechanical interference, and under the action of the torsion spring, it produces a reciprocating elastic movement, driving the filter screen 56 to vibrate periodically. This simple and reliable structure without an additional power source can optimize the vibration frequency through the parameters of the torsion spring and continue until the dust is completely removed. To further improve the cleaning efficiency, a two-way scraping mechanism is designed, and a power mechanism composed of a movable scraping plate 543 made of wear-resistant alloy material and a precision scraping motor is used to achieve precise reciprocating movement to ensure thorough cleaning.

[0050] II. Integrated design of the mechanical system

[0051] Grinding power system: It includes a high-efficiency drive motor with variable frequency speed regulation, a synchronous pulley assembly and a transmission belt, and all components are installed on the strengthened support structure of the frame body 10 to reduce vibration.

[0052] Height adjustment mechanism: The precise positioning of the cylindrical grinding wheel 40 is realized through the first connecting block 421 hinged by a pin shaft, the second connecting block 422 hinged by a self-lubricating bearing, and the lifting mechanism composed of a ball screw 423 and an easy-to-operate rotating handle 424.

[0053] Two-way moving mechanism: The tangential movement is driven by a hydraulic drive slide rail, and the axial movement is realized by a servo motor 821 and an eccentric wheel group to ensure the grinding accuracy.

[0054] III. Automated Workflow

[0055] Grinding Stage: After multiple side plates 01 are installed simultaneously, they are ground comprehensively under the cooperation of the tangential and axial movement mechanisms. The generated metal dust is shunted by the penetration plate 511. Part of it is directly adsorbed by the magnetic adsorption cylinder 521, and part enters the dust suction pipe 53 through the diversion plate. The dust is processed by grading through the filter cotton. Large particles are guided to the magnetic adsorption cylinder 521 by the third diversion plate 523, and the rest flow to the filter screen 56 along the arc-shaped diversion plate 524.

[0056] Cleaning Stage: When the grinding stops and it comes to the material change, the lead screw structure 55 drives the magnetic adsorption cylinder 521 to move, realizing the adsorption of metal dust in the dust on the surface of the filter screen 56. When it reaches the position of the fixed scraping plate 541, it not only scrapes the surface dust but also drives the filter screen to vibrate and clean. When the adsorption amount is large, the movable scraping plate 543 is started to cooperate for reverse cleaning.

[0057] Recovery and Treatment: After the cleaned dust accumulates to the set amount in the storage tank 542, it is transported to the dust treatment device 70 through the sealed pipeline 60. This device realizes the environmental protection treatment and resource recovery of the dust through the sealed box body 71, the adsorption power component 72 and the water washing system.

[0058] Through the coordinated operation of the above system, the whole process automation treatment from grinding processing to dust recovery is realized, significantly improving the cleaning and environmental protection level of the processing of Pilates bed accessories.

[0059] Embodiment 2

[0060] Referring to Figure 8 , on the basis of Embodiment 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 Embodiment 1 is maintained, as well as the settings of core components such as the magnetic adsorption cylinder 521 and the dust suction pipe 53.

[0061] The innovation lies in that the penetration plate 511 adopts a design of an inner and outer double-layer honeycomb unit composite structure. It is integrally arched and forms an inclination angle of 15 - 20° with the horizontal plane.

[0062] The inner mesh cloth (on the side close to the grinding area) adopts a design of small-sized honeycomb units with a dense layout but the same spacing (side length 6 - 8 mm). There are 2 - 3 layers of deep corrugations (peak height 3 - 4 mm) formed on the inner peripheral surface, and the mesh hole diameter is relatively small (0.8 - 1.0 mm). This structural design can provide stronger deformation buffering ability and achieve precise filtration.

[0063] The outer mesh is designed with large-sized honeycomb cells (side length 15 - 18 mm) corresponding to the number and position of small-sized honeycomb cells, and 5 - 6 layers of shallow corrugations (peak height 1.5 - 2 mm) are formed on the inner peripheral surface, with a relatively large mesh diameter (1.2 - 1.5 mm). The outer mesh is evenly distributed radially on the arched surface, and the central axis of each large-sized honeycomb cell points to the focus of the arch. To improve the separation effect, the honeycomb cells in the outer layer are arranged out of alignment with those in the inner layer, so that the upper boundaries of the outer-layer cells coincide with the upper boundaries of the inner-layer cells.

[0064] There is a gap between the two layers of mesh, and this gap forms a cavity with a variable cross-section. The distance is 3 mm near the inner side of the arch and gradually increases to 5 mm outward. When dust passes through, both the small-sized and large-sized honeycomb cells generate vibration and buffering effects. Part of the dust changes its movement trajectory in the cavity with variable cross-section under the resonance effect of the two layers of mesh. Through the cooperation of the corrugated structures of the inner and outer meshes and the cavity with variable cross-section, multiple shunting and filtering are formed. This structure not only prolongs the dust movement path, but the independent vibration and resonance of the two layers of mesh can also generate an eddy current effect to enhance the separation effect. In addition, based on the flexible characteristics of the mesh material, the outer surface of the arched structure generates high-frequency and intense structural oscillations under the continuous impact of dust. This oscillation forms a strong dynamic collision with the dust naturally falling in the second treatment 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 dust capture efficiency.

[0065] The double-layer composite structure of this embodiment achieves efficient absorption and caching of dust through ingenious design. The inner and outer layer mesh fabrics work synchronously. The large-sized honeycomb units in the outer layer and the small-sized honeycomb units in the inner layer are in one-to-one correspondence in position, and their upper boundaries coincide and are arranged radially pointing to the focus on the arched surface, forming a continuous filtering channel. The design of the arched surface makes the dust flow downward naturally when entering, and the arrangement radially pointing to the focus enables each honeycomb unit to receive the incoming flow at the optimal angle. The upper space of the large-sized honeycomb units 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 structures of the inner and outer layers at the same time. The corrugations and mesh holes 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, causing the dust to form a spiral movement trajectory when passing through, significantly prolonging the residence time of the dust in the system. In addition, the independent vibration and resonance effects of the two layer mesh fabrics form a stable eddy current field in the cavity, further prolonging the dust movement path and enhancing the absorption effect. Particularly, each honeycomb unit forms an independent accommodation space, which can temporarily store the incompletely filtered dust, and the overflowing dust will naturally fall into the honeycomb units below and continue to be captured, forming a multi-stage caching and circulating filtering system. This structural design not only enables the dust to undergo multiple filtering and absorption processes through natural forces, but also provides sufficient caching space, ensuring that the dust is captured step by step and minimizing the probability of dust rebound and escape.

[0066] The overall framework of this embodiment is bent into an arch shape using lightweight aluminum alloy profiles, and through precision machining, the guide grooves on the inner and outer sides of the profiles are ensured to maintain concentric arcs. The framework is designed with a quick disassembly and assembly mechanism, which is convenient for daily cleaning and maintenance while ensuring airtightness.
