Therefore, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 5 A preferred embodiment of the dustproof polishing equipment according to this application will be described in detail below. The dustproof polishing equipment is used to polish semi-finished products to remove burrs, scratches, etc., from the surface of the semi-finished products, thereby improving the flatness and smoothness of the surface. The semi-finished products can be metal or plastic products.

[0027] Specifically, the dustproof polishing equipment includes a body 10, a polishing mechanism 20, a protective mechanism 30, and a conveyor mechanism 40.

[0028] The equipment body 10 includes an equipment body 11 and a support platform 12. The equipment body 11 has a lower end 111 and a higher end 112 above the lower end 111. The support platform 12 is installed on the lower end 111, and a support surface 1201 is formed along the horizontal plane at one end of the support platform 12 facing the higher end 112 for supporting the semi-finished product.

[0029] The polishing mechanism 20 includes a polishing component 21 and a mounting base 22, wherein the polishing component 21 is mounted on the mounting base 22. The polishing component 21 has a polishing surface 2101, which faces the side wall of the support platform 12 and is opposite to the wall to be polished formed by the semi-finished product. The polishing component 21 polishes the wall to be polished formed by the semi-finished product by rotating the polishing surface 2101 relative to the semi-finished product.

[0030] The lower end portion 111 has a starting end portion 11101 and a ending end portion 11102 disposed opposite to the starting end portion 11101. The mounting base 22 is movably mounted on the lower end portion 111 in a manner driven by the conveyor mechanism 40 to reciprocate between the starting end portion 11101 and the ending end portion 11102. The direction extending from the starting end portion 11101 to the ending end portion 11102 is parallel to the length direction of the wall to be polished formed by the semi-finished product. In this way, when the mounting base 22 is driven by the conveyor mechanism 40 to move from the starting end portion 11101 to the ending end portion 11102, the mounting base 22 drives the polishing assembly 21 to fully polish the wall to be polished formed by the semi-finished product.

[0031] The protective mechanism 30 includes two protective covers 31, both of which are connected to the mounting base 22, and each of the two protective covers 31 has an end furthest from the mounting base 22 connected to the lower end 111. The protective covers 31 can be retractably laid above the pipeline connected to the polishing assembly 21 and the conveyor mechanism 40 in the direction in which the conveyor mechanism 40 drives the mounting base 22 to move, for covering the pipeline connected to the polishing assembly 21 and the conveyor mechanism 40. When the mounting base 22 is driven by the conveyor mechanism 40 to move between the starting end 11101 and the ending end 11102, one of the protective covers 31 is pulled and unfolded by the mounting base 22 to expand the protection area of ​​the protective cover 31 for the pipeline connected to the polishing assembly 21 and the conveyor mechanism 40; the other protective cover 31 is compressed by the pressure of the mounting base 22 to make room for the movement of the mounting base 22. In this way, the two protective covers 31 and the mounting base 22 work together to cover the pipeline connected to the polishing assembly 21 and the conveyor mechanism 40 to prevent debris and dust generated during the polishing process from falling into the pipeline, avoid short circuits caused by debris and dust, and ensure normal operation of the equipment.

[0032] Preferably, the polishing assembly 21 includes a drive member 211 and a polishing disc 212, wherein the polishing disc 212 forms the polishing surface 2101. The drive member 211 is mounted on the mounting base 22, and the polishing disc 212 is rotatably connected to the drive member 211. Specifically, the drive member 211 drives the polishing disc 212 to rotate, so that the polishing disc 212 polishes the wall of the semi-finished product to be polished.

[0033] As an example, the drive component 211 is implemented to include a motor.

[0034] In one embodiment, the protective cover 31 includes a plurality of interconnected folded portions 311. Each folded portion 311 forms a first connecting protrusion 3111 facing away from the connecting line between the polishing assembly 21 and the conveyor belt mechanism 40, and a second connecting protrusion 3112 facing the connecting line between the polishing assembly 21 and the conveyor belt mechanism 40, respectively, between two adjacent folded portions 3111. When the protective cover 31 is compressed by the mounting base 22, the horizontal linear distance between the first connecting protrusion 3111 and the adjacent first connecting protrusion 3111 gradually decreases, while the vertical linear distance gradually increases. When the protective cover 31 is stretched by the mounting base 22, the horizontal linear distance between the first connecting protrusion 3111 and the adjacent first connecting protrusion 3111 gradually increases, while the vertical linear distance gradually decreases.

[0035] Preferably, the lower end portion 111 forms a sliding groove 11103 between the starting end portion 11101 and the ending end portion 11102. A limiting protrusion 3113 is formed between every two folded portions 311, and the limiting protrusion 3113 is slidably inserted into the sliding groove 11103 formed in the lower end portion 111. The limiting protrusion 3113 and the sliding groove 11103 cooperate with each other to ensure that the protective cover 31 remains in contact with the lower end portion 111 during extension and retraction, so as to prevent the protective cover 31 from tilting up due to uneven force during extension and retraction.

[0036] In a preferred embodiment, the conveyor mechanism 40 includes a rotating component 41, a conveyor gear 42, and a conveyor rack 43. The rotating component 41 is mounted on the mounting base 22, wherein the conveyor gear 42 is rotatably connected to the rotating component 41, and the conveyor gear 42 meshes with the conveyor rack 43. The conveyor rack 43 is mounted on the lower end 111 and extends between the starting end 11101 and the ending end 11102. Thus, when the conveyor gear 42 is driven to rotate by the rotating component 41, the conveyor gear 42 moves along the extending direction of the conveyor rack 43 while rotating, causing the conveyor gear 42 to drive the polishing mechanism 20 to move via the rotating component 41, thereby allowing the polishing disc 212 to fully polish the wall to be polished formed from the semi-finished product.

[0037] As an example, the rotating component 41 is implemented to include a motor.

[0038] Furthermore, the dustproof polishing equipment also includes a fixing mechanism 50. The fixing mechanism 50 is movably mounted on the equipment body 11 in a manner that allows it to approach and move away from the semi-finished product located on the support surface 1201, so as to fix the semi-finished product on the support surface 1201 and prevent the semi-finished product from shaking during polishing.

[0039] Preferably, the fixing mechanism 50 includes a driving member 51 and a fixing member 52, the driving member 51 being mounted on the equipment body 11. The fixing member 52 faces the semi-finished product located on the support surface 1201, and the fixing member 52 is drivably connected to the driving member 51, the driving member 51 being used to drive the fixing member 52 toward and away from the semi-finished product located on the support surface 1201.

[0040] In one example, the drive member 51 is implemented as a cylinder.

[0041] In one embodiment, the driving member 51 is mounted on the lower end 112, and the driving member 51 drives the fixing member 52 to approach and move away from the semi-finished product located on the support surface 1201 in a horizontal direction, such that the fixing mechanism 50 fixes the semi-finished product from opposite side walls of the semi-finished product.

[0042] In another embodiment, the driving member 51 is mounted on the high end portion 111, and the driving member 51 drives the fixing member 52 to move vertically toward and away from the semi-finished product located on the support surface 1201. The driving member 51 moves the fixing member 52 downward so that the fixing member 52 cooperates with the support platform 12 to fix the semi-finished product.

[0043] Preferably, the dustproof grinding equipment is provided with a plurality of fixing mechanisms 50, which are spaced apart in a direction parallel to the direction extending from the starting end 11101 to the ending end 11102. In this way, the operator can operate the corresponding fixing mechanism 50 according to the size of the semi-finished product, so that the fixing mechanism 50 of the dustproof grinding equipment can fix semi-finished products of different sizes, so that the dustproof grinding equipment can grind semi-finished products of different sizes and improve the practicality of the dustproof grinding equipment.

[0044] Preferably, the fixing mechanism 50 further includes a buffer pad 53, which is installed on the side wall of the fixing member 52 facing the semi-finished product. When the driving member 51 drives the fixing member 52 to approach the semi-finished product located on the support surface 1201, the buffer pad 53 is located between the fixing member 52 and the semi-finished product to prevent the fixing member 52 from directly contacting the surface of the semi-finished product and to avoid the semi-finished product being scratched by the fixing member 52.

[0045] As an example, the cushioning pad 53 is made of a flexible material; for example, soft rubber.

[0046] Furthermore, the dustproof polishing equipment also includes a position adjustment mechanism 60. The mounting base 22 includes a movable part 221 and a fixed part 222, the fixed part 222 being drivably connected to the belt-moving mechanism 40. The movable part 221 is slidably mounted on the fixed part 222 in a horizontal direction perpendicular to the direction extending from the starting end 11101 to the ending end 11102, driven by the position adjustment mechanism 60. The position adjustment mechanism 60 is used to adjust the distance between the polishing surface 2101 and the wall to be polished formed by the semi-finished product.

[0047] In other words, when the movable part 221 is driven by the position adjustment mechanism 60 to move in a horizontal direction perpendicular to the direction extending from the starting end 11101 to the ending end 11102, the movable part 221 drives the grinding disc 212 to move closer to or further away from the wall to be ground formed by the semi-finished product through the driving member 211. In this way, the distance between the grinding surface 2101 formed by the grinding disc 212 and the wall to be ground formed by the semi-finished product can be adjusted according to the model of the semi-finished product, so that the dustproof grinding equipment can grind semi-finished products of different models or grind semi-finished products of the same model to different degrees.

[0048] Furthermore, when the movable part 221 is driven by the position adjustment mechanism 60 to move away from the support table 12 in a horizontal direction perpendicular to the direction extending from the starting end 11101 to the ending end 11102, the gap between the grinding disc 212 and the support table 12 increases, so that the operator can replace the grinding disc 212.

[0049] In one example, the position adjustment mechanism 60 is implemented as a cylinder.

[0050] Furthermore, the dustproof polishing equipment also includes an angle adjustment mechanism 70.

[0051] The driving member 211 forms a rotating shaft 2111 on the outer wall of the two protective covers 31 on the same side. The movable part 221 is connected to the rotating shaft 2111. The driving member 211 is rotatably connected to the movable part 221 through the rotating shaft 2111, and the axial direction of the rotating shaft 2111 is parallel to the direction extending from the starting end 11101 to the ending end 11102. The angle adjustment mechanism 70 includes an angle adjustment member 71, which is used to drive the driving member 211 to rotate relative to the movable part 221 about the axial direction of the rotating shaft 2111, so as to adjust the angle between the grinding surface 2101 formed by the grinding disc 212 and the vertical plane, so as to facilitate the grinding disc 212 to grind the inclined wall to be ground formed by the semi-finished product.

[0052] In one embodiment, the angle adjustment member 71 includes a rotating worm gear 711, a rotating worm 712, and a rotating element 713, wherein the rotating worm gear 711 and the rotating worm 712 are engaged. Either the rotating worm gear 711 or the rotating worm 712 is connected to the rotating shaft 2111, and the other is connected to the rotating element 713. When the rotating element 713 drives the rotating worm gear 711 or the rotating worm 712 connected to it to rotate, the rotating worm 712 or the rotating worm gear 711 connected to the rotating shaft 2111 drives the driving member 211 to rotate axially around the rotating shaft 2111.

[0053] As an example, the rotating component 713 may be implemented as a lever or a motor.

[0054] Preferably, the angle adjustment mechanism 70 includes a sliding structure 72, which includes a pin 721 and a waist-shaped groove 722. The pin 721 is inserted into the waist-shaped groove 722, and the waist-shaped groove 722 is centered on the axis of the rotation shaft 2111. Either the waist-shaped groove 722 or the pin 721 is disposed in the drive member 211, and the other is disposed in the movable part 221. When the angle adjustment member 71 drives the drive member 211 to rotate relative to the movable part 221 about the rotation shaft 2111, the pin 721 slides relative to the waist-shaped groove 722 within the waist-shaped groove 722, wherein the inner walls forming the two ends of the waist-shaped groove 722 limit the deflection angle of the drive member 211.

[0055] Furthermore, the polishing equipment also includes a dust collection mechanism 80.

[0056] The dust collection mechanism 80 includes a dust suction hood 81 and a negative pressure forming member 82. The dust suction hood 81 forms a dust suction port 8101, and the grinding disc 212 is located directly above the dust suction port 8101. The dust suction port 8101 formed by the dust suction hood 81 is connected to a dust box via a pipe, and the negative pressure forming member 82 is installed on the pipe connecting the dust suction hood 81 and the dust box. The negative pressure forming member 82 draws air from the vicinity of the dust suction port 8101 through the pipe, creating a negative pressure at the dust suction port 8101, and the dust suction hood 81 is connected to the fixing part 222. In this way, the debris and dust generated by the grinding disc 212 grinding the semi-finished product are drawn into the dust suction hood 81 by the negative pressure at the dust suction port 8101 and collected in the dust box through the pipe, thereby reducing debris and dust splashing and avoiding pollution of the working environment.

[0057] As an example, the negative pressure forming element 82 is implemented as a negative pressure pump.

[0058] Preferably, the dust collection mechanism 80 further includes a dust cover 83. The dust cover 83 forms an opening in an installation space 8301 facing the same direction as the grinding surface 2101, the grinding disc 212 is rotatably mounted in the installation space 8301, and the dust cover 83 forms the inner wall of the installation space 8301 to limit the range of debris and dust splashing.

[0059] Preferably, the dust collection mechanism 80 also includes a cleaning brush 84. The cleaning brush 84 is mounted on the dust cover 83, and its orientation is the same as that of the polishing surface 2101. When the polishing mechanism 20 is driven by the conveyor mechanism 40 to move between the starting end 11101 and the ending end 11102, the cleaning brush 84 sweeps away debris and dust adhering to the support platform 12 and the semi-finished product, thus cleaning the support platform 12 and the semi-finished product. The debris and dust swept off by the cleaning brush 84 are collected in the dust box by the dust collection cover 81.
