[0013] In one embodiment, the grinding body includes an inlet / outlet structure and a plurality of grinding cylinders that are connected sequentially and parallel to each other. Each grinding cylinder is arranged around the inlet / outlet structure. The inlet and the outlet are respectively located at opposite ends of the inlet / outlet structure. The first grinding cylinder at the beginning of each grinding cylinder is connected to the inlet / outlet structure near the inlet. The last grinding cylinder at the end of each grinding cylinder is connected to the inlet / outlet structure near the outlet.

[0014] In one embodiment, the feeding and discharging structure includes a return cylinder and a filter cylinder. The inlet is located at one end of the return cylinder, and the filter cylinder is installed in the return cylinder and located near the other end of the return cylinder. The first-end grinding cylinder is connected to the return cylinder, and the last-end grinding cylinder is connected to the filter cylinder. The inner circumferential surface of the return cylinder is provided with a first spiral pusher, and the inner circumferential surface of the filter cylinder is provided with a second spiral pusher. The spiral direction of the first spiral pusher is opposite to that of the second spiral pusher. The peripheral sidewall of the filter cylinder has a through hole, which allows the grinding media to pass through and prevents material from passing through.

[0015] In one embodiment, the filter cartridge is closed at one end facing the feed inlet.

[0016] In one embodiment, the grinding device further includes a first driving mechanism, a driving wheel, and a plurality of driven wheels. The output end of the first driving mechanism is connected to the feeding and discharging structure. The driving wheel is sleeved on the feeding and discharging structure. Each of the driven wheels is sleeved on each of the grinding cylinders. Each of the driven wheels is meshed with the driving wheel.

[0017] In one embodiment, the grinding device further includes a rotating frame and a second driving mechanism; the second driving mechanism is mounted on the fixed frame, the rotating frame is connected to the output end of the second driving mechanism, the feeding and discharging structure and each of the grinding cylinders are mounted on the rotating frame, and the second driving mechanism is used to drive the rotating frame, the feeding and discharging structure and the grinding cylinders to rotate relative to the fixed frame.

[0018] In one embodiment, the rotating frame includes two rotating plates arranged at a distance from each other, the two rotating plates being connected by a connecting rod, the opposite ends of the grinding body being respectively disposed on the two rotating plates, and the output end of the second driving mechanism being connected to one of the rotating plates.

There is no need to stop the machine and disassemble the grinding body before grinding to feed material, nor is there a need to stop the machine and disassemble the grinding body after grinding to discharge material. This not only reduces the difficulty of feeding and discharging operations but also improves feeding and discharging efficiency, thereby increasing grinding efficiency.

Thus, the grinding apparatus can be connected to the material production process to achieve continuous batch production of material, thereby improving material production efficiency.

[0037] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0039] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please see Figure 1 and Figure 2 The grinding apparatus provided in the embodiments of this application will now be described. This grinding apparatus is used to grind metal or non-metal parts to achieve deburring, rust removal, rounding, and bright polishing effects. Its working principle is to cause the material to collide, rub, and shear against the grinding media in the grinding chamber 210, thereby achieving grinding of the material.

[0042] Please see Figure 1 and Figure 2 The grinding device includes a fixed frame 100 and a grinding body 200, the grinding body 200 being rotatably mounted on the fixed frame 100; the grinding body 200 has a grinding chamber 210 for grinding materials, the two ends of the grinding chamber 210 are respectively provided with an inlet 220 and an outlet 230, and the grinding chamber 210 is provided with a pushing part 240 for pushing the material from the inlet 220 to the outlet 230 when the grinding body 200 rotates.

[0043] The cross-sectional area of ​​the grinding chamber 210 can be designed according to the amount of grinding required per unit time, while the length of the grinding chamber 210 is set according to the degree of grinding required for a single material.

[0044] During the grinding process, the grinding body 200 is always rotating, and the material to be ground can be continuously added into the grinding chamber 210 from the feed port 220, and the ground material can be continuously output from the discharge port 230, realizing continuous feeding and discharging.

[0045] The grinding device in this embodiment of the application provides an inlet 220 and an outlet 230 at both ends of the grinding chamber 210, and a pushing part 240 inside the grinding chamber 210 for conveying materials from the inlet 220 to the outlet 230. This allows the grinding device to grind materials by simply driving the grinding body 200 to rotate and continuously adding the material to be ground into the grinding chamber 210 from the inlet 220, and then receiving the ground material from the grinding chamber 210 at the outlet 230. There is no need to stop the machine and disassemble the grinding body 200 to feed materials before grinding, nor is there a need to stop the machine and disassemble the grinding body 200 to discharge materials after grinding. This not only reduces the difficulty of feeding and discharging operations, but also enables continuous feeding and discharging, improving feeding and discharging efficiency and grinding efficiency. Furthermore, since the grinding device in this application can continuously feed and discharge materials, the feed port 220 of the grinding device can be connected to the previous process of the material production process, and the discharge port 230 can be connected to the next process. In this way, the grinding device can be connected to the material production process to realize continuous batch production of materials and improve the production efficiency of materials.

[0046] In one embodiment, see Figure 2 The inlet 220 and outlet 230 are respectively located at opposite ends of the length extension direction of the grinding chamber 210. The pusher 240 is used to push the material along the length extension direction of the grinding chamber 210 so that the material is continuously ground during the forward conveying process to ensure the grinding effect of the material.

[0047] In one embodiment, see Figure 3 The grinding body 200 includes multiple grinding cylinders 260, which are connected sequentially. Specifically, the inner cavities of each grinding cylinder 260 are combined to form a grinding chamber 210. Each grinding cylinder 260 is provided with a pushing part 240, which is used to push the material in the grinding cylinder 260 from one end to the other, and from the grinding cylinder 260 to the next grinding cylinder 260. For ease of description, the grinding cylinder 260 located at the first end is referred to as the first grinding cylinder 260a, and the grinding cylinder 260 located at the last end is referred to as the last grinding cylinder 260. The inlet 220 is located in or connected to the first grinding cylinder 260a, and the outlet 230 is located in or connected to the last grinding cylinder 260. Understandably, in other embodiments of this application, the grinding body 200 may also include a grinding cylinder 260, the inner cavity of which is the grinding chamber 210, and the inlet 220 and outlet 230 are located at opposite ends of the grinding cylinder 260.

[0048] In one embodiment, see Figure 3The grinding body 200 includes a plurality of grinding cylinders 260, which are parallel to each other. The grinding cylinders 260 at least partially overlap along their axial direction and / or at least partially overlap along a first direction X and / or at least partially overlap along a second direction Y, wherein the first direction X, the second direction Y, and the axial direction of the grinding cylinders 260 are mutually perpendicular. This arrangement prevents the grinding cylinders 260 from being sequentially distributed along a single direction, thereby avoiding the area occupied by each grinding cylinder 260 along a single direction, resulting in a compact layout and small space occupation. It is understood that in other embodiments of this application, such as... Figure 4 As shown, the grinding cylinders 260 can also be arranged parallel to each other, and the grinding cylinders 260 can be sequentially connected along the axial direction of the grinding cylinders 260; or, as shown in the figure... Figure 5 As shown, the grinding cylinders 260 can be parallel to each other and distributed sequentially along the first direction X. This is not a unique limitation.

[0049] In one embodiment, see Figure 3 , Figure 6 and Figure 7 The grinding body 200 includes an infeed / outfeed structure 250 and multiple grinding cylinders 260, which are sequentially connected and parallel to each other. Each grinding cylinder 260 is arranged around the infeed / outfeed structure 250. An inlet 220 and an outlet 230 are respectively located at opposite ends of the infeed / outfeed structure 250. The first grinding cylinder 260a at the beginning of each grinding cylinder 260 is connected to the position of the infeed / outfeed structure 250 adjacent to the inlet 220, and the last grinding cylinder 260 at the end of each grinding cylinder 260 is connected to the position of the infeed / outfeed structure 250 adjacent to the outlet 230. By arranging the grinding cylinders 260 around the infeed / outfeed structure 250, not only can the layout of the grinding cylinders 260 be compact, reducing space occupation, but the movement between the infeed / outfeed structure 250 and each grinding cylinder 260 can also be linked, simplifying the drive structure of each grinding cylinder 260.

[0050] In some embodiments, please refer to Figure 2 , Figure 8 and Figure 9The feeding and discharging structure 250 includes a return cylinder 251 and a filter cylinder 252. The inlet 220 is located at one end of the return cylinder 251. The filter cylinder 252 is installed in the return cylinder 251 and is located near the other end of the return cylinder 251. The first grinding cylinder 260a is connected to the return cylinder 251, and the last grinding cylinder 260b is connected to the filter cylinder 252. The inner circumferential surface of the return cylinder 251 is provided with a first spiral pusher 2511, and the inner circumferential surface of the filter cylinder 252 is provided with a second spiral pusher 2521. The spiral direction of the first spiral pusher 2511 is opposite to that of the second spiral pusher 2521. The peripheral sidewall of the filter cylinder 252 has a through hole 2522, which allows the grinding body to pass through and prevents the material from passing through.

[0051] Please see Figure 2 and Figure 8 During normal conveying, the first spiral pusher 2511 conveys the grinding media from the filter cylinder 252 towards the inlet 220, and the second spiral pusher 2521 conveys the material towards the outlet. When the material enters the return cylinder 251 from the inlet 220, due to the presence of the first spiral pusher 2511, the material will not be conveyed in the return cylinder 251, but will flow directly to the first grinding cylinder 260a. After being conveyed sequentially by each grinding cylinder 260, the material flows to the filter cylinder 252 via the end grinding cylinder 260b. In the filter cylinder 252, the material is conveyed towards the outlet 230 and output under the conveying of the second spiral pusher 2521. Meanwhile, since the peripheral wall of the filter cylinder 252 has through holes 2522, the grinding media falls into the return cylinder 251 through the through holes 2522, and is conveyed by the first spiral pusher 2511 in the return cylinder 251 to a position near the inlet 220, and then enters the first end grinding cylinder 260a, realizing the cyclic conveying and cyclic application of the grinding media, so that the grinding media can cyclically grind the material. In this embodiment, the cyclic application of the grinding media can be realized by setting the return cylinder 251 and the filter cylinder 252, saving the usage cost of the grinding media.

[0052] In some embodiments, please refer to Figure 2 and Figure 8 The return cylinder 251 is provided with a first interface 2512 near the feed inlet 220. The first end grinding cylinder 260a is connected to the first interface 2512 through a first connector 290. One end of the first connector 290 is rotatably sleeved with the first interface 2512, and the other end of the first connector 290 is rotatably sleeved with the first end grinding cylinder 260a.

[0053] In some embodiments, please refer to Figure 10The end of the first connector 290 is provided with a sealing check valve 291. The sealing check valve 291 allows the material to flow from the first connector 290 to the first grinding cylinder 260a, but prevents the material from flowing back from the first grinding cylinder 260a to the first connector 290, thereby ensuring that the material can smoothly pass through each grinding cylinder 260 in sequence from the feed port 220 and flow out from the discharge port 230.

[0054] Specifically, the sealing check valve 291 is made of metal.

[0055] In some embodiments, please refer to Figure 2 and Figure 9 The filter cylinder 252 is provided with a second interface 2523 near the discharge port 230, and the end grinding cylinder 260b is connected to the second interface 2523 through the second connector 270.

[0056] In some embodiments, please refer to Figure 2 The filter cylinder 252 is closed at one end facing the feed inlet 220. This arrangement prevents material from falling into the return cylinder 251 and flowing back towards the feed inlet 220, thus realizing the recycling of material discharge and auxiliary materials such as grinding media. In addition, when the material grinding time is insufficient, each grinding cylinder 260 can be reversed to increase the material grinding time.

[0057] In one embodiment, see Figure 6 and Figure 7 The grinding device also includes a first drive mechanism 400, a drive wheel 600 and a plurality of driven wheels 700. The output end of the first drive mechanism 400 is connected to the feeding and discharging structure 250. The drive wheel 600 is sleeved on the feeding and discharging structure 250. Each driven wheel 700 is sleeved on each grinding cylinder 260. Each driven wheel 700 is meshed with the drive wheel 600.

[0058] When the first drive mechanism 400 drives the feeding and discharging structure 250 to rotate, the feeding and discharging structure 250 drives the drive wheel 600 to rotate. Since the drive wheel 600 is engaged with each driven wheel 700, it drives each driven wheel 700 and each grinding cylinder 260 to rotate.

[0059] In this embodiment, by arranging the positions of each grinding cylinder 260 and by setting up the driving wheel 600 and each driven wheel 700, it is possible to drive the feeding / discharging structure 250 to rotate only through the first driving mechanism 400, which can synchronously drive each grinding cylinder 260 to rotate. This eliminates the need for a separate driving mechanism for each grinding cylinder 260, significantly reducing the cost and space occupied by the driving mechanism. It is understood that in other embodiments of this application, when each grinding cylinder 260 is arranged in a different manner, a driving mechanism can be provided for each grinding cylinder 260, or a single driving mechanism can be used to drive multiple grinding cylinders 260 to rotate via gear transmission outside each grinding cylinder 260. This is not a limiting factor.

[0060] In one embodiment, see Figure 6 and Figure 7 The grinding device also includes a rotating frame 300 and a second drive mechanism 500; the second drive mechanism 500 is mounted on the fixed frame 100, the rotating frame 300 is connected to the output end of the second drive mechanism 500, the feeding and discharging structure 250 and each grinding cylinder 260 are mounted on the rotating frame 300, and the second drive mechanism 500 is used to drive the rotating frame 300, the feeding and discharging structure 250 and the grinding cylinder 260 to rotate relative to the fixed frame 100.

[0061] In this embodiment, through the arrangement of the first driving mechanism 400, the second driving mechanism 500 and the rotating frame 300, the first driving mechanism 400 can drive the feeding and discharging structure 250 and each grinding cylinder 260 to rotate relative to the rotating frame 300. At the same time, the second driving mechanism 500 can drive the rotating frame 300 to rotate relative to the fixed frame 100, thereby driving the feeding and discharging structure 250 and the grinding cylinder 260 to revolve. That is, the feeding and discharging structure 250 and the grinding cylinder 260 can rotate while rotating. The rotation allows the material in the feeding and discharging structure 250 and each grinding cylinder 260 to move forward in their respective inner cavities, and the revolve allows the material in each grinding cylinder 260 to enter the next grinding cylinder 260 laterally, so that the material moves forward and is ground sequentially in each grinding cylinder 260.

[0062] In one embodiment, the rotating frame 300 includes two rotating plates arranged at a distance from each other, connected by a connecting rod (not shown). The two ends of the grinding body 200 are respectively disposed on the two rotating plates, and the output end of the second driving mechanism 500 is connected to one of the rotating plates. The second driving mechanism 500 can drive one of the rotating plates to rotate, thereby driving both rotating plates to rotate through the connecting rod, and thus driving the grinding body 200 to revolve.

[0063] For details, please refer to Figure 6 and Figure 7The grinding body 200 has two rotating plates, namely a first rotating plate 310 and a second rotating plate 320. One end of the grinding body 200 with a feed inlet 220 is rotatably mounted on the first rotating plate 310, and the other end of the grinding body 200 with a discharge outlet 230 is mounted on the second rotating plate 320. The output end of the second driving mechanism 500 is connected to the second rotating plate 320, thereby driving the grinding body 200 to revolve.

[0064] In one embodiment, see Figure 6 and Figure 7 The rotating plate is circular, with the center line of the feed inlet 220 of the grinding body 200 coinciding with the center line of the rotating plate; the center line of the discharge outlet 230 of the grinding body 200 also coincides with the center line of the rotating plate. This arrangement ensures that the feed inlet 220 and discharge outlet 230 remain centered on the rotating plate during rotation, facilitating connection between the feed inlet 220 and the outlet 230 with the inlet of the next process. This prevents the feed inlet 220 and discharge outlet 230 from changing their positions on the rotating plate during rotation, thus avoiding the need for connection.

[0065] Specifically, the first rotating plate 310 and the second rotating plate 320 are arranged in parallel and facing each other, with the center lines of the first rotating plate 310 and the second rotating plate 320 coinciding. The center line of the inlet 220 coincides with the center line of the first rotating plate 310, and the center line of the outlet 230 coincides with the center line of the second rotating plate 320. This ensures that during the rotation process, the position of the inlet 220 on the first rotating plate 310 remains unchanged, and the position of the outlet 230 on the second rotating plate 320 remains unchanged.

[0066] In one embodiment, see Figure 6 and Figure 7 The grinding body 200 includes an infeed / outfeed structure 250 and multiple grinding cylinders 260. The infeed / outfeed structure 250 is rotatably mounted on a first rotating plate 310 and a second rotating plate 320 at its opposite ends. Similarly, the grinding cylinders 260 are rotatably mounted on the first rotating plate 310 and the second rotating plate 320 at their opposite ends. The centerline of the infeed / outfeed structure 250 coincides with the centerline of the first rotating plate 310. The inlet 220 is located at the end of the infeed / outfeed structure 250 away from the second rotating plate 320. The end of the infeed / outfeed structure 250 with the inlet 220 extends out of the first rotating plate 310 to allow material to enter. Each grinding cylinder 260 is arranged around the infeed / outfeed structure 250. When the second drive mechanism 500 drives the first rotating plate 310 and the second rotating plate 320 to rotate, the infeed / outfeed structure 250 and each grinding cylinder 260 rotate along with the first rotating plate 310 and the second rotating plate 320. Simultaneously, the first drive mechanism 400 drives the infeed / outfeed structure 250 and each grinding cylinder 260 to rotate on their own axes.

[0067] In one embodiment, see Figure 6 A connecting cylinder 280, U-shaped, connects two adjacent grinding cylinders 260, with its opposite ends rotatably connected to each of the two adjacent grinding cylinders 260. This connection cylinder 280 not only connects the two grinding cylinders 260, allowing material to be transferred from one to the other, but also ensures that the two grinding cylinders 260 are arranged parallel and spaced apart. Furthermore, the rotatable connection between the connecting cylinder 280 and the grinding cylinders 260 prevents the connecting cylinder 280 from affecting the rotation of the two grinding cylinders 260.

[0068] In one embodiment, see Figure 7 Each connecting cylinder 280 is located on the outside of the first rotating plate 310 and the second rotating plate 320, so that the opposite ends of each grinding cylinder 260 can be rotated and set on the first rotating plate 310 and the second rotating plate 320 respectively, ensuring the rotational stability of each grinding cylinder 260.

[0069] In one embodiment, see Figure 6 and Figure 7 The first drive mechanism 400 and the second drive mechanism 500 are respectively located on opposite outer sides of the two rotating plates. Specifically, the first drive mechanism 400 is located on the side of the first rotating plate 310 opposite to the second rotating plate 320, and its output end is connected to the inlet 220 of the feeding / discharging structure 250 extending outside the first rotating plate 310. The second drive mechanism 500 is located on the side of the second rotating plate 320 opposite to the first rotating plate 310, and its output end is connected to the second rotating plate 320.

[0070] In one embodiment, see Figure 7 The first drive mechanism 400 and the second drive mechanism 500 are both belt drive mechanisms. It is understood that in other embodiments of this application, the first drive mechanism 400 and the second drive mechanism 500 may also be other mechanisms capable of outputting rotary motion, such as a motor with a gear reducer, or a rotary motor or a rotary cylinder; this is not a unique limitation.

[0071] In one embodiment, see Figure 11 The pushing part 240 is formed on the inner peripheral wall of the grinding chamber 210. The pushing part 240 is in the shape of a thin sheet and extends continuously or in segments along the length of the grinding chamber 210. Specifically, when the grinding chamber 210 extends continuously, the pushing part 240 can extend continuously in a spiral within the grinding chamber 210; when the grinding chamber 210 is segmented, the pushing part 240 can extend segmentally in a spiral within the grinding chamber 210. When the grinding cylinder 260 rotates, the pushing part 240 can push the material forward in a spiral.
