[0040] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0041] Please refer to Figure 1 and Figure 2 , and now the grinding device provided by the embodiment of the present application will be described. This grinding device is used to grind metal or non-metal component products to achieve the effects of deburring, derusting, chamfering, and bright polishing. Its working principle is to make the material collide, rub, and shear with the grinding medium in the grinding chamber 210, thereby realizing the grinding of the material.

[0042] Please refer to Figure 1 and Figure 2 , the grinding device includes a fixing frame 100 and a grinding main body 200. The grinding main body 200 is rotatably arranged on the fixing frame 100; the grinding main body 200 has a grinding chamber 210 for grinding the material. Both ends of the grinding chamber 210 are respectively provided with a feeding port 220 and a discharging port 230. A pushing part 240 is arranged in the grinding chamber 210 to push the material to be conveyed from the feeding port 220 towards the discharging port 230 when the grinding main body 200 rotates.

[0043] Among them, the cross-sectional area of the grinding chamber 210 can be designed according to the grinding amount to be completed per unit time, and 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 main body 200 is always in a rotating state, and the material to be ground can be continuously added into the grinding chamber 210 from the feeding port 220, and the ground material can be continuously output at the discharging port 230, realizing continuous feeding - discharging.

[0045] In the grinding device according to the embodiment of the present application, by respectively arranging a feeding port 220 and a discharging port 230 at both ends of the grinding chamber 210, and a pushing part 240 for conveying materials from the feeding port 220 to the discharging port 230 direction is arranged in the grinding chamber 210, when the grinding device grinds materials, it only needs to drive the grinding main body 200 to rotate, continuously add the materials to be ground into the grinding chamber 210 from the feeding port 220, and then receive the materials that have been ground in the grinding chamber 210 at the discharging port 230. There is no need to stop the machine and disassemble the grinding main body 200 for feeding before grinding, nor to stop the machine and disassemble the grinding main body 200 for discharging after grinding. This not only reduces the operation difficulty of feeding and discharging, but also can realize continuous feeding and discharging, improves the feeding and discharging efficiency, and improves the grinding efficiency. In addition, since the grinding device in the present application can continuously feed and discharge materials, the feeding port 220 of the grinding device can be connected to the previous process of the material production process, and the discharging 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, please refer to Figure 2 , the feeding port 220 and the discharging port 230 are respectively arranged at opposite ends in the length extension direction of the grinding chamber 210, and the pushing part 240 is used to push the materials along the length extension direction of the grinding chamber 210, so that the materials are continuously ground during the forward conveying process to ensure the grinding effect of the materials.

[0047] In one embodiment, please refer to Figure 3 , the grinding main body 200 includes a plurality of grinding cylinders 260, and the grinding cylinders 260 are sequentially communicated. Specifically, the inner cavities of the grinding cylinders 260 together form the grinding chamber 210, and a pushing part 240 is arranged in each grinding cylinder 260. The pushing part 240 is used to push the materials in the grinding cylinder 260 from one end of the grinding cylinder 260 to the other end, and push the materials from the grinding cylinder 260 to the next grinding cylinder 260. For the convenience of description, the grinding cylinder 260 at the head end among the grinding cylinders 260 is set as the head-end grinding cylinder 260a, and the grinding cylinder 260 at the tail end is set as the tail-end grinding cylinder 260. The feeding port 220 is located in the head-end grinding cylinder 260a or communicated with the head-end grinding cylinder 260a, and the discharging port 230 is located in the tail-end grinding cylinder 260 or communicated with the tail-end grinding cylinder 260. It can be understood that in other embodiments of the present application, the grinding main body 200 may also include a grinding cylinder 260, and the inner cavity of the grinding cylinder 260 is the grinding chamber 210, and the feeding port 220 and the discharging port 230 are respectively located at opposite ends of the grinding cylinder 260.

[0048] In one embodiment, please refer to Figure 3, the grinding body 200 includes a plurality of grinding cylinders 260, each grinding cylinder 260 is parallel to each other, each grinding cylinder 260 at least partially overlaps along the axial direction of the grinding cylinder 260 and / or each grinding cylinder 260 at least partially overlaps along the first direction X and / or the grinding cylinder 260 at least partially overlaps along the second direction Y, wherein the first direction X, the second direction Y and the axial direction of the grinding cylinder 260 are perpendicular to each other in pairs. With such a setting, each grinding cylinder 260 will not be distributed in sequence along a certain direction, thereby avoiding the occupied area of each grinding cylinder 260 along a certain direction, making the layout of each grinding cylinder 260 compact and occupying a small space. It can be understood that in other embodiments of the present application, such as Figure 4 as shown, each grinding cylinder 260 can also be parallel to each other, and each grinding cylinder 260 can be connected and distributed in sequence along the axial direction of the grinding cylinder 260; or, it can also be like Figure 5 as shown, each grinding cylinder 260 can be parallel to each other, and each grinding cylinder 260 can be distributed in sequence along the first direction X, and there is no unique limitation here.

[0049] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7 , the grinding body 200 includes a feeding and discharging structure 250 and a plurality of grinding cylinders 260, each grinding cylinder 260 is connected in sequence and parallel to each other; each grinding cylinder 260 is arranged around the feeding and discharging structure 250, the feeding port 220 and the discharging port 230 are respectively arranged at opposite ends of the feeding and discharging structure 250, and the first-end grinding cylinder 260a of each grinding cylinder 260 at the first end is connected to the position of the feeding and discharging structure 250 adjacent to the feeding port 220, and the last-end grinding cylinder 260 of each grinding cylinder 260 at the last end is connected to the position of the feeding and discharging structure 250 adjacent to the discharging port 230. Among them, by arranging each grinding cylinder 260 around the feeding and discharging structure 250, not only can the layout of each grinding cylinder 260 be made compact and the occupied space be reduced, but also the movement between the feeding and discharging structure 250 and each grinding cylinder 260 can be linked, making the driving structure of each grinding cylinder 260 simple.

[0050] In some embodiments, please refer to Figure 2 , Figure 8 and Figure 9, the feeding and discharging structure 250 includes a return material cylinder 251 and a filter cylinder 252. The feeding port 220 is provided at one end of the return material cylinder 251. The filter cylinder 252 is installed in the return material cylinder 251 and is arranged near the other end of the return material cylinder 251. The first grinding cylinder 260a at the head end is communicated with the return material cylinder 251, and the second grinding cylinder 260b at the tail end is communicated with the filter cylinder 252. A first spiral pusher 2511 is provided on the inner peripheral surface of the return material cylinder 251, and a second spiral pusher 2521 is provided on the inner peripheral surface of the filter cylinder 252. The spiral direction of the first spiral pusher 2511 is opposite to that of the second spiral pusher 2521. The peripheral side wall of the filter cylinder 252 has through holes 2522 which can allow the grinding media to pass through and can prevent the materials from passing through.

[0051] Please refer to Figure 2 and Figure 8 , during the normal conveying process, the first spiral pusher 2511 is used to convey the grinding media from the filter cylinder 252 towards the feeding port 220, and the second spiral pusher 2521 is used to convey the materials towards the discharging port. When the materials enter the return material cylinder 251 from the feeding port 220, due to the existence of the first spiral pusher 2511, the materials will not be conveyed in the return material cylinder 251 but directly flow towards the first grinding cylinder 260a at the head end. After the materials are successively conveyed through each grinding cylinder 260, they flow towards the filter cylinder 252 through the last grinding cylinder 260b at the tail end. The materials are conveyed towards the discharging port 230 and output under the conveying of the second spiral pusher 2521 in the filter cylinder 252. At the same time, due to the through holes 2522 on the peripheral side wall of the filter cylinder 252, the grinding media will fall into the return material cylinder 251 through the through holes 2522 and are conveyed to a position near the feeding port 220 in the return material cylinder 251 under the conveying of the first spiral pusher 2511 in the return material cylinder 251 and then enter the first grinding cylinder 260a at the head end, realizing the circulating conveying and recycling application of the grinding media, so that the grinding media can cyclically grind the materials. In this embodiment, through the arrangement of the return material cylinder 251 and the filter cylinder 252, the recycling application of the grinding media can be realized, saving the use cost of the grinding media.

[0052] In some embodiments, please refer to Figure 2 and Figure 8 , a first interface 2512 is provided at a position of the return material cylinder 251 near the feeding port 220. The first grinding cylinder 260a at the head end is connected to the first interface 2512 through a first connecting member 290. One end of the first connecting member 290 is rotatably sleeved with the first interface 2512, and the other end of the first connecting member 290 is rotatably sleeved with the first grinding cylinder 260a at the head end.

[0053] In some embodiments, please refer to Figure 10, a sealing check valve 291 is provided at the end of the first connecting member 290. Among them, the sealing check valve 291 allows the material to flow from the first connecting member 290 to the first grinding cylinder 260a at the head end, but prevents the material from flowing back from the first grinding cylinder 260a at the head end to the first connecting member 290, so as to ensure that the material can smoothly pass through each grinding cylinder 260 in sequence from the feed inlet 220 and flow out from the discharge outlet 230.

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

[0055] In some embodiments, please refer to Figure 2 and Figure 9 , a second interface 2523 is provided at a position of the filter cylinder 252 close to the discharge outlet 230, and the last grinding cylinder 260b is connected to the second interface 2523 through a second connecting member 270.

[0056] In some embodiments, please refer to Figure 2 , one end of the filter cylinder 252 facing the feed inlet 220 is closed. The above setting can prevent the material from falling into the return cylinder 251 and flowing back towards the feed inlet 220, realizing the recycling of the discharged material and auxiliary materials such as grinding media. In addition, when the grinding time of the material is insufficient, each grinding cylinder 260 can also be reversely rotated to increase the grinding time of the material.

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

[0058] When the first driving mechanism 400 drives the feeding and discharging structure 250 to rotate, the feeding and discharging structure 250 drives the driving wheel 600 to rotate. Since the driving wheel 600 is respectively meshed and connected with each driven wheel 700, each driven wheel 700 and each grinding cylinder 260 are driven to rotate.

[0059] In this embodiment, by arranging the positions of the grinding cylinders 260 and setting the driving wheel 600 and each driven wheel 700, only the feeding and discharging structure 250 needs to be driven by the first driving mechanism 400 to rotate, so as to synchronously drive the rotation of each grinding cylinder 260, without setting a driving mechanism for each grinding cylinder 260, greatly reducing the cost and occupied space of the driving mechanism. It can be understood that in other embodiments of the present application, when the grinding cylinders 260 are arranged in other ways, a driving mechanism can also be set for each grinding cylinder 260, or the rotation of multiple grinding cylinders 260 can be driven by one driving mechanism through a gear transmission method outside the grinding cylinders 260, which is not uniquely limited here.

[0060] In one embodiment, please refer to Figure 6 and Figure 7 , the grinding device further includes a rotating frame 300 and a second driving mechanism 500; the second driving mechanism 500 is installed on the fixed frame 100, the rotating frame 300 is connected to the output end of the second driving mechanism 500, the feeding and discharging structure 250 and each grinding cylinder 260 are installed on the rotating frame 300, and the second driving 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 setting of the first driving mechanism 400, the second driving mechanism 500 and the rotating frame 300, the feeding and discharging structure 250 and each grinding cylinder 260 can be driven by the first driving mechanism 400 to rotate relative to the rotating frame 300 around their own axes, and at the same time, the rotating frame 300 can be driven by the second driving mechanism 500 to rotate relative to the fixed frame 100, so as to drive 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 revolve while rotating around their own axes. Among them, the rotation around their own axes can make the materials in the feeding and discharging structure 250 and each grinding cylinder 260 move forward in their respective inner cavities, and the revolution can make the materials in each grinding cylinder 260 enter the next grinding cylinder 260 horizontally, so that the materials are ground in sequence in each grinding cylinder 260.

[0062] In one embodiment, the rotating frame 300 includes two rotating plates arranged at intervals relatively, and the two rotating plates are connected by a connecting rod (not shown in the figure). The opposite ends of the grinding main body 200 are respectively arranged 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, so as to drive the two rotating plates to rotate through the connecting rod, and further drive the grinding main body 200 to revolve.

[0063] Specifically, please refer to Figure 6 and Figure 7, two rotating plates are provided, namely a first rotating plate 310 and a second rotating plate 320. One end of the grinding body 200 having the material inlet 220 is rotatably provided on the first rotating plate 310, and one end of the grinding body 200 having the material outlet 230 is provided 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 a circular plate, and the center line of the feed inlet 220 of the grinding body 200 coincides with the center line of the rotating plate; the center line of the discharge port 230 of the grinding body 200 coincides with the center line of the rotating plate. This arrangement allows the feed inlet 220 and the discharge port 230 to always be located at the center of the rotating plate during the rotation of the rotating plate, thereby facilitating the docking of the feed inlet 220 with the outlet of the previous process and the discharge port 230 with the entrance of the next process, thereby avoiding the change of the position of the feed inlet 220 and the discharge port 230 on the rotating plate during the rotation of the rotating plate without forming a docking.

[0065] Specifically, the first rotating plate 310 and the second rotating plate 320 are arranged parallel to each other, the center lines of the first rotating plate 310 and the second rotating plate 320 coincide with each other, the center line of the feed port 220 coincides with the center line of the first rotating plate 310, and the center line of the discharge port 230 coincides with the center line of the second rotating plate 320, thereby ensuring that during the rotation process, the position of the feed port 220 on the first rotating plate 310 remains unchanged, and the position of the discharge port 230 on the second rotating plate 320 remains unchanged.

[0066] In one embodiment, see Figure 6 and Figure 7 The grinding body 200 includes a material inlet and outlet structure 250 and a plurality of grinding cylinders 260. The opposite ends of the material inlet and outlet structure 250 are respectively rotatably disposed on the first rotating plate 310 and the second rotating plate 320. The opposite ends of each grinding cylinder 260 are respectively rotatably disposed on the first rotating plate 310 and the second rotating plate 320. The center line of the material inlet and outlet structure 250 is arranged to coincide with the center line of the first rotating plate 310. The material inlet 220 is located at the end of the material inlet and outlet structure 250 away from the second rotating plate 320. The end of the material inlet and outlet structure 250 having the material inlet 220 extends out of the first rotating plate 310 for material feeding. Each grinding cylinder 260 is arranged around the material inlet and outlet structure 250. When the second driving mechanism 500 drives the first rotating plate 310 and the second rotating plate 320 to rotate, the material inlet and outlet structure 250 and each grinding cylinder 260 rotates along with the first rotating plate 310 and the second rotating plate 320. At the same time, the first driving mechanism 400 drives the material inlet and outlet structure 250 and each grinding cylinder 260 to rotate.

[0067] In one embodiment, seeFigure 6 A connecting tube 280 is connected between two adjacent grinding cylinders 260. The connecting tube 280 is U-shaped, and the opposite ends of the connecting tube 280 are respectively rotatably connected to the two adjacent grinding cylinders 260. In this way, through the setting of the connecting tube 280, not only can the two grinding cylinders 260 be connected, so that the material in one grinding cylinder 260 can be transferred to the next grinding cylinder 260, but also the two grinding cylinders 260 can be arranged in parallel and spaced apart. In addition, the rotatable connection between the connecting tube 280 and the grinding cylinder 260 ensures that the connecting tube 280 does not affect 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 disposed on the first rotating plate 310 and the second rotating plate 320, respectively, to ensure the rotation stability of each grinding cylinder 260.

[0069] In one embodiment, see Figure 6 and Figure 7 , the first driving mechanism 400 and the second driving mechanism 500 are respectively arranged on the opposite outer sides of the two rotating plates. Specifically, the first driving mechanism 400 is arranged on the side of the first rotating plate 310 away from the second rotating plate 320, and the output end of the first driving mechanism 400 is connected to the inlet 220 of the inlet and outlet structure 250 extending out of the first rotating plate 310. The second driving mechanism 500 is arranged on the side of the second rotating plate 320 away from the first rotating plate 310, and the output end of the second driving mechanism 500 is connected to the second rotating plate 320.

[0070] In one embodiment, see Figure 7 , the first drive mechanism 400 is a belt transmission mechanism, and the second drive mechanism 500 is a belt transmission mechanism. It can be understood that in other embodiments of the present application, the first drive mechanism 400 and the second drive mechanism 500 can also be other mechanisms capable of outputting rotational motion, such as a motor plus a gear reducer mechanism, or a rotary motor or a rotary cylinder, which is not limited here.

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

[0072] In one embodiment, please refer to Figure 12 , the grinding device further includes a shield 800. The shield 800 is installed on the fixing frame 100 and covers the upper part of the grinding main body 200, the rotating frame 300, the first driving mechanism 400, the second driving mechanism 500, the driving wheel 600 and the driven wheel 700, so as to shield and protect the above structures.

[0073] Specifically, please refer to Figure 12 , the fixing frame 100 is formed by connecting multiple cross beams and multiple longitudinal beams to enclose a box shape. The fixing frame 100 has an opening at the top. The shield 800 is in a box shape and has an opening at the bottom. The shield 800 is buckled on the fixing frame 100 from top to bottom, so as to enclose a cavity for accommodating the grinding main body 200, the rotating frame 300, the first driving mechanism 400, the second driving mechanism 500, the driving wheel 600 and the driven wheel 700.

[0074] In another embodiment of the present application, the grinding device further includes a first driving mechanism 400, a rotating frame 300 and a second driving mechanism 500. The second driving mechanism 500 is installed on the fixing frame 100. The rotating frame 300 is connected to the output end of the second driving mechanism 500. The grinding main body 200 is rotatably arranged in the rotating frame 300. The output end of the first driving mechanism 400 is connected to the grinding main body 200 and is used to drive the grinding main body 200 to rotate relative to the rotating frame 300.

[0075] In this embodiment, the grinding main body 200 may include a grinding cylinder 260, or may include multiple grinding cylinders 260 connected in sequence. The grinding cylinders 260 in the grinding main body 200 may be distributed in a shape as shown in Figure 3 , or may be distributed in a rectangular, square, circular, oval or other irregular shapes; or may be distributed in a shape as shown in Figure 4 and Figure 5 , which is not uniquely limited here.

[0076] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
