Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a polishing device for alloy rods with a dust-collecting structure. Background Technology

[0002] The working principle of grinding equipment usually involves using abrasives or grinding tools to cut or grind the surface of a workpiece to remove defects such as burrs, oxide layers, and tool marks, and to achieve the required surface roughness and dimensional accuracy. After cutting, forging or heat treatment, alloy bars often have burrs, oxide layers or tool marks remaining on their surface. Grinding can eliminate these defects and avoid cracks or poor adhesion in subsequent processing (such as welding and spraying).

[0003] Existing grinding equipment generates a large amount of fine dust and particulate matter during the grinding process of alloy bars. This dust not only suspends in the air, but also adheres to the equipment, workpieces and the surrounding environment, leading to a deterioration of the production environment.

[0004] For example, the high-temperature alloy master alloy rod grinding device disclosed in patent CN221248252U does not have a dust collection mechanism. Because of the lack of a dust collection mechanism, the dust generated during grinding will permeate the entire working area, which will not only affect the operator's vision, but may also lead to a decline in the air quality of the working environment. In addition, the dust generated will adhere to the equipment surface, the ground and surrounding objects, increasing the difficulty and frequency of cleaning. This not only wastes manpower and resources, but may also lead to dust accumulation due to untimely cleaning, further deteriorating the production environment. Moreover, working in a dusty environment for a long time, the operator is likely to inhale a large amount of dust, thereby affecting the operator's health.

[0005] Therefore, it is necessary to invent an alloy rod processing and grinding device with a dust-collecting structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an alloy rod processing and grinding device with a dust-collecting structure to solve the problem of the lack of a dust-collecting mechanism in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an alloy rod processing and grinding device with a dust-collecting structure, comprising a body, a cover being provided above the body, two tempered glass hinged doors on the front side of the cover, a grinding mechanism and a limiting mechanism being provided inside the cover, a dust-collecting mechanism being provided at the rear side of the body, the dust-collecting mechanism comprising a bracket and a dust-collecting fan, the dust-collecting fan being located on the bracket, a dust-collecting pipe being connected to the air inlet end of the dust-collecting fan, the air inlet end of the dust-collecting pipe extending through the top of the cover into its interior, a dust-filtering mechanism being provided between the air outlet end of the dust-collecting pipe and the air inlet end of the dust-collecting fan, the dust-filtering mechanism comprising a filter box, the filter box being installed on the dust-collecting pipe, and a first filter screen and a second filter screen being slidably installed inside the filter box.

[0008] Preferably, the grinding mechanism includes a housing and a servo motor. The housing is mounted on the top surface of the machine body by four bolts. The servo motor is located inside the housing. A grinding wheel is provided on one side of the outer side of the housing. The center of the grinding wheel is connected to the output end of the servo motor. The grinding wheel is covered with a transparent PC material protective cover. The housing protects the motor from dust and debris interference and extends its service life.

[0009] Preferably, a limiting mechanism is provided on the front side of the grinding mechanism. The limiting mechanism includes two uprights located on the left and right sides of the top surface of the machine body. A lower limiting wheel is provided on each upright, and an upper limiting wheel is provided above the lower limiting wheel. The lower limiting wheel provides stable support. The lower limiting wheel and the upper limiting wheel work together to limit the radial displacement of the bar during processing.

[0010] Preferably, the limiting mechanism further includes a mounting frame, the shaft ends of the upper limit wheel are mounted on both sides of the inner wall of the mounting frame, a cylinder is provided on the top surface of the upright frame, the output end of the cylinder is connected to the top surface of the mounting frame, the protrusions on the front and rear sides of the mounting frame are slidably connected to the wall of the upright frame, the cylinder drives the mounting frame to rise and fall, thereby realizing the height adjustment of the upper limit wheel and adapting to the processing needs of bars of different diameters.

[0011] Preferably, the aperture of the first filter screen is larger than that of the second filter screen. The side walls of the first and second filters screens are provided with convex sliders. The contact position between the convex sliders and the inner wall of the filter box is provided with matching convex grooves. The graded filtration improves the dust collection efficiency, and the convex sliders and convex grooves cooperate to realize the quick replacement of the filters.

[0012] Preferably, a dust collection box is provided at the bottom of the filter box, and a groove is provided on the top surface of the dust collection box extending through to the bottom surface inside the filter box. A pull-out cabinet is provided inside the dust collection box. The dust collection box collects the dust filtered by the filter screen, and the groove ensures that the dust falls smoothly into the pull-out cabinet.

[0013] Preferably, the outer walls on both sides of the pull-out cabinet are provided with concave sliders, and the contact positions between the concave sliders and the inner walls of the dust collection box are provided with matching concave grooves. The pull-out cabinet is slidably connected to the dust collection box through the concave sliders, which facilitates the disassembly of the pull-out cabinet for easy dust cleaning.

[0014] Preferably, the outer wall of the dust collection box is provided with bearing seats on both sides, and a rotating plate is hinged on the bearing seats. A fixing bolt is connected through the rotating plate and extends to the side wall of the drawer cabinet. A matching screw hole is opened at the contact position between the fixing bolt and the side wall of the drawer cabinet. The fixing bolt passes through the rotating plate and is screwed into the screw hole of the side wall of the drawer cabinet to realize the locking and unlocking of the drawer cabinet.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The cover in this utility model forms an independent closed area through the front hinged door, completely isolating the grinding work area from the outside world. This structure directly blocks the dust diffusion path through a physical barrier, ensuring that the dust generated during the processing is confined inside the cover and prevents it from leaking into the workshop environment. In addition, the suction pipe, together with the strong suction of the suction fan, forms a directional airflow channel inside the cover. The airflow flows unidirectionally from the grinding area to the suction pipe, forcing the dust to enter the suction mechanism with the airflow, thereby achieving centralized collection and efficient removal of dust.

[0017] 2. The dust filtration mechanism in this utility model adopts a double-layer filter structure. The first filter (large pore size) intercepts large dust particles, while the second filter (small pore size) further filters fine particles. This graded filtration effectively prevents dust from directly entering the vacuum fan, preventing wear on the fan blades and blockage of the air duct, and reducing maintenance costs. At the same time, the first and second filters are slidably connected to the inner wall of the filter box via a convex slider, enabling quick disassembly and replacement. Therefore, the modular filter design facilitates regular cleaning or replacement, ensuring long-term stable vacuuming efficiency. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The apparatus shown is an alloy rod processing and polishing device with a dust-collecting structure, comprising a body 1, a cover 2 on the top of the body 1, two tempered glass hinged doors 3 on the front of the cover 2, a polishing mechanism 4 and a limiting mechanism 5 inside the cover 2, and a dust-collecting mechanism 6 on the rear of the body 1. The dust-collecting mechanism 6 includes a bracket 601 and a dust-collecting fan 602, the dust-collecting fan 602 is located on the bracket 601, the air inlet end of the dust-collecting fan 602 is connected to a dust-collecting pipe 603, the air inlet end of the dust-collecting pipe 603 extends through the top of the cover 2 and into its interior, and a dust-filtering mechanism 7 is provided between the air outlet end of the dust-collecting pipe 603 and the air inlet end of the dust-collecting fan 602, the dust-filtering mechanism 7 including a filter box 701, the filter box 701 is installed on the dust-collecting pipe 603, and a first filter screen 702 and a second filter screen 703 are slidably installed inside the filter box 701.

[0028] The grinding mechanism 4 includes a housing 401 and a servo motor 402. The housing 401 is mounted on the top surface of the body 1 by four bolts. The servo motor 402 is located inside the housing 401. A grinding wheel 403 is provided on one side of the housing 401. The center of the grinding wheel 403 is connected to the output end of the servo motor 402, and the grinding wheel 403 is covered with a transparent PC material protective cover. A limit mechanism 5 is provided on the front side of the grinding mechanism 4. The limit mechanism 5 includes two uprights 501. 01 is located on the left and right sides of the top surface of the body 1. The support frame 501 is equipped with a lower limit wheel 502, and an upper limit wheel 503 is provided above the lower limit wheel 502. The limiting mechanism 5 also includes a mounting frame 504. The shaft ends on both sides of the upper limit wheel 503 are installed on the inner wall of the mounting frame 504. A cylinder 505 is provided on the top surface of the support frame 501. The output end of the cylinder 505 is connected to the top surface of the mounting frame 504. The protrusions on the front and rear sides of the mounting frame 504 are slidably connected to the wall of the support frame 501.

[0029] In this embodiment, the chassis 401 can isolate dust and debris, preventing them from entering the servo motor 402 and extending its lifespan. The lower limit wheel 502 provides basic support, ensuring that the bar remains horizontal during processing. The lower limit wheel 502 works in conjunction with the lower limit wheel 502 to limit the radial displacement of the bar, preventing it from shaking during processing and ensuring that the grinding wheel 403 is aligned with the bar's axis. The height of the mounting bracket 504 can be adjusted by extending and retracting the cylinder 505, thereby changing the position of the upper limit wheel 503 to adapt to the processing requirements of bars with different diameters. At the same time, the protrusion of the mounting bracket 504 is slidably connected to the upright frame 501, ensuring that the upper limit wheel 503 moves smoothly and avoids jamming or displacement.

[0030] The aperture of filter screen 702 is larger than that of filter screen 703. The side walls of filter screen 702 and filter screen 703 are provided with convex sliders 704. The contact position between the convex sliders 704 and the inner wall of filter box 701 is provided with matching convex grooves 705. The bottom of filter box 701 is provided with a dust collection box 8. The top surface of dust collection box 8 is provided with a groove 9 extending through to the bottom surface of filter box 701. The interior of dust collection box 8 is provided with a pull-out cabinet 10.

[0031] In this embodiment, filter 702 has a larger aperture and is located at the air inlet, while filter 703 has a smaller aperture and is located at the air outlet. Therefore, filter 702 intercepts large dust particles, while filter 703 captures fine particles, ensuring the cleanliness of the exhaust air. The cooperation between the convex slider 704 and the convex groove 705 allows filter 702 and filter 703 to be directly pulled out or inserted along the convex groove 705, allowing for replacement without tools. This modular design allows for the individual replacement of clogged filter 702 or filter 703, avoiding the need to disassemble the entire filter box 701 and improving equipment usability. Furthermore, the dust and impurities filtered by filter 702 and filter 703 can fall into the pull-out cabinet 10 through the trough 9 for collection.

[0032] The outer walls of both sides of the drawer cabinet 10 are provided with concave sliders 11. The concave sliders 11 are provided with matching concave grooves 12 at the contact positions with the inner walls of the dust collection box 8. The outer walls of the dust collection box 8 are provided with bearing seats 13 on both sides. A rotating plate 14 is hinged to the bearing seat 13. A fixing bolt 15 is passed through the rotating plate 14 and extends to the side wall of the drawer cabinet 10. The fixing bolt 15 is provided with matching screw holes 16 at the contact positions with the side wall of the drawer cabinet 10.

[0033] In this embodiment, the concave slider 11 on the side wall of the pull-out cabinet 10 and the concave groove 12 on the inner wall of the dust collection box 8 cooperate to allow the pull-out cabinet 10 to be pulled out smoothly, facilitating centralized dust cleaning. The pull-out cabinet 10 can hold a large amount of dust, reducing the cleaning frequency. Furthermore, the threaded design of the fixing bolts 15 and the screw holes 16 can limit and fix the sliding pull-out cabinet 10, effectively preventing it from sliding out. The bolts can be loosened to unlock it during cleaning. Therefore, the graded filtration and the dust collection box 8 work together to form a complete closed loop of "interception-collection-cleaning", achieving efficient filtration to reduce dust emissions, protect the air quality in the workshop, and meet environmental protection requirements.

[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figure 1-3 When using this utility model, first, open the switch door 3, place the alloy rod to be processed on the lower limit wheel 502, start the cylinder 505 to adjust the height of the upper limit wheel 503 so that the alloy rod is clamped between the lower limit wheel 502 and the upper limit wheel 503, then turn on the servo motor 402 to drive the grinding wheel 403 to rotate at high speed to grind the limited rod. When the rod is being ground, turn on the dust extraction fan 602 to suck the dust generated by grinding into the filter box 701 through the dust extraction pipe 603. The dust-laden air first passes through the first filter screen 702. Large particles of dust such as metal shavings and gravel are intercepted and fall into the drawer cabinet 10 of the dust collection box 8 through the trough 9. The remaining fine particles, such as grinding dust, pass through the second filter screen 703 and also fall into the drawer cabinet 10 through the trough 9 for centralized collection.

[0036] Refer to the instruction manual appendix Figure 4-6 When using this utility model, if the first filter 702 and the second filter 703 become clogged, causing a decrease in suction power, turn off the polishing device and the dust collector 602. Pull out the clogged first filter 702 or second filter 703 along the convex slide 705 without tools, clean or replace it, and then reinsert it. When the drawer cabinet 10 is full of dust, loosen the fixing bolt 15 on the rotating plate 14 so that the fixing bolt 15 is disengaged from the screw groove on the drawer cabinet 10. Then pull out the drawer cabinet 10 along the concave slide 12, empty the dust, push it back, and tighten the fixing bolt 15.

[0037] This device achieves dust collection and environmentally friendly emissions during alloy bar grinding by using a graded filtration system: a first filter screen 702 to cut off large particles, a second filter screen 703 to capture fine dust, and a modular design that allows for quick replacement of the first filter screen 702, the second filter screen 703, and the pull-out cabinet 10. This significantly improves processing efficiency and workshop environmental quality.
