Description

Technical Field

[0001] This invention relates to the technical field of mixing and granulation equipment, and particularly to mixing chambers and mixing equipment. Background Technology

[0002] Internal mixing equipment is mainly used for the plasticizing and mixing of MIM and CIM. Typically, an internal mixing equipment consists of a mixing chamber and a rotor rotating inside the mixing chamber. When plasticizing or mixing MIM and CIM, the raw materials are fed into the mixing chamber for internal mixing. The raw materials are sheared and extruded under the rotation of the rotor, thereby obtaining a relatively uniformly mixed MIM and CIM product.

[0003] However, when current internal mixers are used to mix different batches of products, the mixing chamber will contain residues from the previous batch, which may lead to a decrease in the quality of the next batch of products. Summary of the Invention

[0046] See Figure 1 , Figure 1 A schematic diagram of a mixing apparatus according to an embodiment of the present invention is shown. The mixing apparatus provided in one embodiment of the present invention includes a frame 900 and a mixing chamber. The mixing chamber is located on the top of the frame 900. The mixing chamber can mix raw materials to obtain the corresponding product. The frame 900 provides support for the mixing chamber.

[0047] Combination Figure 2 As shown, Figure 2 A schematic diagram of a mixing chamber according to one embodiment of the present invention is shown. In some embodiments, the mixing chamber includes a main body 100 and a mixing structure 400. The main body 100 has a mixing space 110, and the mixing structure 400 can mix the raw materials located within the main body 100.

[0048] In some embodiments, such as Figures 1-4 As shown, the main body 100 includes a first cavity wall 200 and a second cavity wall 300. The second cavity wall 300 is detachably connected to the first cavity wall 200. When the second cavity wall 300 and the first cavity wall 200 are closed relative to each other, the second cavity wall 300 and the first cavity wall 200 define a mixing space 110. Raw materials can be mixed within the mixing space 110. The mixing structure 400 is detachably connected to the first cavity wall 200. The portion of the mixing structure 400 located in the mixing space 110 is rotatable relative to the mixing space 110.

[0049] The second cavity wall 300 and the first cavity wall 200 are detachably configured, allowing them to be opened relative to each other after the previous product has been mixed, thus separating the mixing structure 400 from the first cavity wall 200. This ensures that the surfaces of the first cavity wall 200, the second cavity wall 300, and the mixing structure 400 can all be cleaned, eliminating cleaning dead corners. This prevents some product residue from remaining in the cleaning dead corners of the mixing space 110 after the previous product has been mixed, which could cause the two products to mix during the mixing of the next product. This configuration improves the quality of product mixing.

[0050] In some embodiments, the first cavity wall 200 includes a back plate 210 and at least one outer plate 220. The outer plate 220 is detachably connected to the back plate 210. The side of the outer plate 220 away from the back plate 210 is detachably connected to the second cavity wall 300. This detachable connection between the back plate 210 and the outer plate 220 allows the space formed by the back plate 210 and the outer plate 220 to be adjusted according to actual needs when the first cavity wall 200 is opened relative to the second cavity wall 300, exposing cleaning dead zones to the outside that can be cleaned with tools.

[0051] In some embodiments, such as Figure 3 As shown, the first cavity wall 200 includes a back plate 210 and two outer side plates 220, which are detachably connected to opposite sides of the back plate 210. The connection between the outer side plates 220 and the back plate 210 can be via snap-fit, plug-in, screw connection, or hinge connection. In some embodiments, a housing 230 is also provided on the side of the back plate 210 away from the second cavity wall 300, which can accommodate a portion of the mixing structure 400. The housing 230 can be fixedly connected to the frame 900 or detachably connected to the frame 900, for example, via bolt connection.

[0052] In the illustrated embodiment, the outer side plate 220 and the back plate 210 are detachably connected via a pivot 240. The outer side plate 220 has at least two spaced-apart first connecting portions 221. The back plate 210 or the housing 230 has a second connecting portion 211, which may be located in the gap between adjacent first connecting portions 221. Both the first connecting portions 221 and the second connecting portions 211 are provided with through holes, so that the pivot 240 can pass through the first first connecting portion 221, the second connecting portion 211, and the second first connecting portion 221 in sequence. It should be noted that the through hole of the first connecting portion 221 closest to the machine tool can be closed on the side of the through hole closest to the frame 900. The outer side plate 220 can rotate relative to the back plate 210 along the axis of the pivot 240.

[0053] The aforementioned method of connecting the outer side plate 220 and the back plate 210 via the pivot 240 allows the outer side plate 220 to rotate relative to the back plate 210 during the cleaning of the first cavity wall 200, thereby exposing the cleaning dead space between the outer side plate 220 and the back plate 210 to the outside. Furthermore, this arrangement eliminates the need for alignment of the outer side plate 220 and the back plate 210 during the reinstallation of the main body 100, facilitating the installation of the first cavity wall 200.

[0054] like Figure 3 As shown, in some embodiments, the outer side plate 220 includes a first segment 222 and a second segment 223 connected to each other.

[0055] The first segment 222 is detachably connected to the back plate 210. That is, the first segment 222 may be provided with the aforementioned first connecting part 221 or second connecting part 211.

[0056] The second segment 223 is detachably connected to the side of the second cavity wall 300 away from the first cavity wall 200. For example, in some embodiments, the second segment 223 can be connected to the second cavity wall 300 by means of snap-fit, plug-in or other connection methods.

[0057] like Figure 2 and Figure 3 As shown, the mixing chamber also includes a connector 250. The connector 250 can pass through the second section 223 and be detachably connected to the second cavity wall 300. The connector 250 can be connected to the second cavity wall 300 via a threaded connection; that is, the outer wall of the connector 250 has external threads, and the second cavity wall 300 has a corresponding threaded hole, with the connector 250 corresponding to the threaded hole. In some other embodiments, the connector 250 can also be snapped onto the second cavity wall 300 via the second section 223.

[0058] In some embodiments, the first segment 222 and the second segment 223 can be fixedly connected. For example, the first segment 222 and the second segment 223 can be connected by welding, integral molding, separate molding followed by integral assembly, or screw connection. In the illustrated embodiment, the second segment 223 can be connected to the side of the first segment 222 closest to the mixing space 110. The length direction of the second segment 223 and the first segment 222 can be perpendicular. This arrangement makes it easy for the second segment 223 to be connected to the side of the second cavity wall 300 away from the first cavity wall 200.

[0059] In some embodiments, such as Figure 2 and Figure 4 As shown, the second cavity wall 300 includes a front plate 310 and an inner cavity wall 320. The front plate 310, the inner cavity wall 320, and the first cavity wall 200 define the aforementioned mixing space 110.

[0060] Specifically, in some embodiments, the two opposing sidewalls of the inner cavity wall 320 are through-through. The front plate 310 is connected to one through-through sidewall of the inner cavity wall 320, and the first cavity wall 200 is detachably connected to the other through-through sidewall of the inner cavity wall 320. That is, the inner cavity wall 320 and the front plate 310 provide the bottom wall and most of the sidewalls of the mixing space 110, while the first cavity wall 200 provides the remaining sidewalls. In the illustrated embodiment, the cross-sectional shape of the inner cavity wall 320 is U-shaped. That is, the inner cavity wall 320 provides the two opposing sidewalls and the bottom wall of the mixing space 110.

[0061] The above-described configuration can minimize the connection gaps within the mixing space 110 and reduce residue in these gaps. Furthermore, this configuration minimizes the number of parts to be disassembled from the main body 100 while ensuring zero cleaning dead zones, making it easier for workers to assemble and disassemble the second cavity wall 300 and the first cavity wall 200.

[0062] In some embodiments, the front plate 310 and the inner cavity wall 320 can be fixedly connected, and the connection method can be welding, bolting, or other methods. The surface where the front plate 310 and the inner cavity wall 320 are connected forms one side of the mixing space 110.

[0063] When the first cavity wall 200 and the second cavity wall 300 are closed relative to each other, the back plate 210 and the front plate 310 are positioned opposite each other. The surface where the back plate 210 connects to the inner cavity wall 320 forms another side of the mixing space 110. Specifically, in the illustrated embodiment, the back plate 210 abuts against the side of the inner cavity wall 320 away from the front plate 310. The first segment 222 of the outer plate 220 abuts against the non-through side wall of the inner cavity wall 320, and the second segment 223 is detachably connected to the side of the front plate 310 away from the back plate 210. In the illustrated embodiment, the second segment 223 can be detachably connected to the front plate 310 via the aforementioned connector 250.

[0064] In some embodiments, such as Figures 2-5 As shown, the mixing chamber also includes a locking structure 800. The locking structure 800 can lock the first cavity wall 200 and the second cavity wall 300, making the connection between the first cavity wall 200 and the second cavity wall 300 more stable.

[0065] In some embodiments, the locking structure 800 includes a locking member 801. One end of the locking member 801 is fixedly connected to the first cavity wall 200. The other end of the locking member 801 is detachably connected to the second cavity wall 300. This arrangement allows the locking member 801 to be disconnected from the second cavity wall 300 only at one end when the second cavity wall 300 is opened relative to the first cavity wall 200. Compared to a method where the locking member 801 is completely detached from both the first cavity wall 200 and the second cavity wall 300, the above technical solution is more convenient for assembly and disassembly.

[0066] In some embodiments, such as Figure 3 As shown, the locking component 801 includes a locking block 810 and a locking rod 830. The locking block 810 is fixedly disposed on the first cavity wall 200. The connection method can be a bolt connection or other connection method. The locking block 810 can be connected to the housing 230. The locking rod 830 is detachably connected to the locking block 810. The second cavity wall 300 is provided with a insertion groove 321. The end of the locking rod 830 can extend into the insertion groove 321 and is detachably connected to the groove wall of the insertion groove 321.

[0067] In some embodiments, combined Figure 2 , Figure 3 and Figure 5 The locking structure 800 also includes a fastener 802. The fastener 802 can connect the groove wall of the insertion slot 321 to the locking rod 830 so that the two can be detachably connected.

[0068] In the illustrated embodiment, such as Figure 4 As shown, the side wall of the second cavity is provided with a insertion groove 321. The inner cavity wall 320 is provided with the aforementioned insertion groove 321, which extends to the side of the front plate 310 away from the back plate 210. Figures 2-5 The end of the locking rod 830 extends into the insertion slot 321. The end of the locking rod 830 may be flush with the side of the front plate 310 away from the back plate 210, or it may protrude or be recessed into the front plate 310. The fastener 802 may pass through one side wall of the insertion slot 321, the locking rod 830, and the other side wall of the insertion slot 321 to connect the locking member 801 to the side wall of the insertion slot 321.

[0069] In some embodiments, such as Figure 5 As shown, the locking block 810 includes a base 820 and a first moving block 824 and a second moving block 825 movably disposed on the base 820. One side of the locking rod 830 abuts against the first moving block 824, and the other side of the locking rod 830 abuts against the second moving block 825. By changing the positions of the first moving block 824 and the second moving block 825 relative to the base 820, the position of the locking rod 830 relative to the base 820 can be adjusted, so that even with movement errors, the locking rod 830 can be adjusted to a suitable position and connected to the second cavity wall 300.

[0070] In some embodiments, the outer side plate 220 can be connected to the back plate 210 by connecting it to the substrate 820.

[0071] In some embodiments, the base 820 includes a middle plate 821, a first plate 822, and a second plate 823 disposed opposite to each other. The first plate 822 and the second plate 823 are spaced apart. A first movable block 824 is movably disposed with respect to the first plate 822. A second movable block 825 is movably disposed with respect to the second plate 823. The arrangement of the first plate 822 and the second plate 823 makes it easier for the first movable block 824 and the second movable block 825 to connect to the base 820. The sides of the first plate 822 and the second plate 823 away from the middle plate 821 are both connected to the housing 230. The middle plate 821 can be connected to the aforementioned outer plate 220.

[0072] like Figure 5As shown, the first plate 822 and the second plate 823 are respectively disposed at both ends of the middle plate 821, and both the first plate 822 and the second plate 823 extend toward the same side of the middle plate 821. The first plate 822 and the second plate 823 are provided with connecting structures along their extending direction, and the connecting structures can be connected to the box 230 in the first cavity. The connecting structure can be a connecting slot 826, a connecting protrusion, etc. When the connecting structure is a connecting slot 826, a connecting rod such as a bolt can be used to pass through the connecting slot 826 and be fixedly connected to the first cavity. When the connecting structure is a connecting protrusion, the connection can be achieved by engaging the connecting protrusion with the connecting hole opened on the surface of the first cavity wall 200.

[0073] In some embodiments, combined with Figure 3 and Figure 5 The locking block 810 also includes an adjusting rod 812. One end of the adjusting rod 812 abuts against the first moving block 824 or the second moving block 825. The adjusting rod 812 passes through the corresponding first plate 822 or second plate 823. The adjusting rod 812 is movably disposed relative to the first plate 822 or the second plate 823, so that the position of the first moving block 824 or the second moving block 825 relative to the base 820 can be moved. This facilitates the adjustment of the position of the locking member 801.

[0074] In some embodiments, the structures of the first moving block 824 and the second moving block 825 may be the same or similar. The following description uses the first moving block 824 as an example.

[0075] The first plate 822 has an adjustment groove 811 along the direction away from the second plate 823. The adjustment groove 811 is a threaded through hole. The adjustment rod 812 is a threaded rod. The adjustment rod 812 can be threadedly connected to the adjustment groove 811. The adjustment rod 812 passes through the adjustment groove 811 and abuts against the first moving block 824. By rotating the adjustment rod 812, the length of the portion of the adjustment rod 812 passing through the adjustment groove 811 can be changed, thereby changing the position of the first moving block 824 relative to the base 820.

[0076] When the locking rod 830 is installed with the locking block 810, the locking rod 830 is partially located in the accommodating space formed between the middle plate 821, the first moving block 824, the second moving block 825, and the side wall of the box 230.

[0077] In some embodiments, a rolling element 813 is provided on the side of the first moving block 824 and / or the second moving block 825 near the locking member 801. The rolling element 813 is rotatable relative to the base 820. The outer edge of the rolling element 813 abuts against the locking rod 830. By providing the rolling element 813, the frictional force between the locking rod 830 and the first moving block 824 and / or the second moving block 825 when the locking rod 830 moves relative to the locking block 810 during the installation of the locking rod 830 and the locking block 810 can be effectively reduced.

[0078] In the illustrated embodiment, the rolling element 813 can be either a bearing 814 or a roller. When the rolling element 813 is a bearing 814, it can be rotatably connected to the corresponding first moving block 824 or second moving block 825 via a bearing pin 815.

[0079] In some embodiments, both the first moving block 824 and the second moving block 825 have at least one mounting groove for accommodating a rolling element 813 on the side near the locking rod 830. The mounting groove can accommodate one rolling element 813 or at least two rolling elements 813 simultaneously. The number of rolling elements 813 is two or more. The outer edge of the rolling element 813 near the locking rod 830 protrudes beyond the plane of the opening of the mounting groove.

[0080] In the illustrated embodiment, there are ten rolling elements 813. Five rolling elements 813 are rotatably disposed on the first moving block 824 at intervals, and the other five rolling elements 813 are rotatably disposed on the second moving block 825 at intervals. This arrangement can distribute the force among multiple rolling elements 813, thereby improving their service life. In some embodiments, the bearing 814 can be an HK1010 needle roller bearing.

[0081] When installing the locking structure 800, the positions of the base 820, the first moving block 824, and the second moving block 825 can be determined first, and then the locking rod 830 can be placed between the first moving block 824 and the second moving block 825. The pre-positioned locking block 810 and the locking rod 830 are installed into the first cavity through the connecting structure. The locking rod 830 and the adjusting rod 812 are moved so that the locking rod 830 can be engaged with the insertion groove 321 of the second cavity wall 300. When the first cavity wall 200 and the second cavity wall 300 are fastened, the locking rod 830 extends into the insertion groove 321, and the fastener 802 connects the groove wall of the insertion groove 321 with the locking rod 830, thus completing the locking of the first cavity wall 200 and the second cavity wall 300.

[0082] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, a support member 700 is provided at the bottom of the inner cavity wall 320. The end of the support member 700 away from the inner cavity wall 320 can be connected to the frame 900. The support member 700 can provide a certain support force for the inner cavity wall 320 and the product contained during mixing, thereby reducing the gravitational force on the connection between the first cavity wall 200 and the second cavity wall 300, and reducing the instability of the connection between the first cavity wall 200 and the second cavity wall 300 due to their own weight.

[0083] In the illustrated embodiment, the support member 700 includes a first support portion 710 and a second support portion 720.

[0084] The first support portion 710 can abut against the inner cavity wall 320. In some other embodiments, the first support portion 710 can be connected to the bottom of the inner cavity wall 320 by welding, insertion, or other means.

[0085] The second support portion 720 is connected to the frame 900. The connection can be fixed, movable, or abutment-like. In the illustrated embodiment, the second support portion 720 is movably connected to the frame 900. The frame 900 is provided with a guide rail 910 along the direction from the front plate 310 to the back plate 210. The second support portion 720 has a sliding groove on the side away from the first support portion 710, which can slide and connect with the guide rail 910. This arrangement facilitates support of the second cavity wall 300 when it separates from the first cavity wall 200.

[0086] The first support portion 710 can slide relative to the second support portion 720 along the direction from the bottom surface of the inner cavity wall 320 to the frame 900. This arrangement allows the height of the support member 700 along the direction from the frame 900 to the inner cavity wall 320 to be adjustable. This configuration ensures that the support member 700 can still provide support to the second cavity wall 300 even when using second cavity walls of different thicknesses or when there are certain errors in the manufacturing process of the second cavity wall 300.

[0087] In the illustrated embodiment, the first support portion 710 abuts against the inner cavity wall 320 and has external threads. The second support portion 720 has a threaded hole that is threadedly connected to the first support portion 710. When the first support portion 710 rotates relative to the second support portion 720, the distance between the surface of the first support portion 710 away from the second support portion 720 and the frame 900 is adjusted, thereby matching the height of the second cavity wall 300 relative to the frame 900.

[0088] In some embodiments, the second cavity wall 300 is provided with mounting holes. These mounting holes can be used to install external handles, facilitating the separation of the first cavity wall 200 from the second cavity wall 300 by an operator. In some embodiments, there are two mounting holes, respectively located on opposite sides of the second cavity wall 300. This arrangement ensures that the second cavity wall 300 experiences more even force when pulled by the handle, facilitating its movement.

[0089] In some embodiments, the mixing structure 400 is detachably connected to the first cavity wall 200.

[0090] Specifically, such as Figures 1-3As shown, the mixing structure 400 includes a driving member 410 and a rotating member 420. The driving member 410 is disposed on the outside of the main body 100. The driving member 410 and the rotating member 420 are detachably connected. The end of the rotating member 420 away from the driving member 410 passes through the first cavity wall 200, so that when the second cavity wall 300 is closed relative to the first cavity wall 200, the rotating member 420 is located within the mixing space 110. The driving member 410 drives the rotating member 420 to rotate relative to the mixing space 110, thereby achieving mixing of the product.

[0091] In some embodiments, the number of rotating members 420 is two or more. The rotating members 420 are arranged in parallel and spaced apart. The axial direction of the rotating members 420 is consistent with the direction from the back plate 210 to the front plate 310. The two rotating members 420 rotate in opposite directions and rotate relative to each other.

[0092] In some embodiments, the number of driving members 410 may be the same as the number of rotating members 420, and one driving member 410 drives one rotating member 420. In other embodiments, the number of driving members 410 is one. The mixing structure 400 also includes a transmission assembly 430. The driving members 410 are connected to the transmission assembly 430, and the transmission assembly 430 can be connected to all rotating members 420 simultaneously, thereby driving all rotating members 420 to rotate simultaneously.

[0093] In the illustrated embodiment, the drive unit 410 can be a motor or other drive device. The drive shaft 411 of the motor is detachably connected to the transmission assembly 430. The transmission assembly 430 includes a connecting bushing 431, a first gear 432, and a second gear 433.

[0094] The connecting sleeve 431 can be fitted onto the outside of the drive shaft 411. The connecting sleeve 431 can be connected to the drive shaft 411 via a flat key to achieve synchronous rotation. The connecting sleeve 431 can also be connected to the drive shaft 411 via bolts for a detachable connection.

[0095] A first gear 432 is coaxially fixedly connected to the side of the connecting sleeve 431 away from the drive shaft 411. The side of the first gear 432 away from the connecting sleeve 431 is coaxially connected to a rotating component 420. A second gear 433 meshes with the first gear 432. The side of the second gear 433 away from the drive shaft 411 is coaxially connected to another rotating component 420.

[0096] In the illustrated embodiment, both the first gear 432 and the second gear 433 are disposed inside the housing 230, and the connecting bushing 431 can be disposed on the side of the housing 230 away from the back plate 210.

[0097] like Figures 1-2As shown, a discharge component 500 is provided on the side of the front plate 310 away from the first cavity wall 200. The discharge component 500 can discharge the product in the mixing space 110.

[0098] Combination Figure 3 and Figure 4 In some embodiments, the discharge component 500 is a screw sleeve. The discharge component 500 communicates with the second cavity wall 300, so that the space inside the discharge component 500 communicates with the mixing space 110. The first cavity wall 200 is provided with a discharge screw 600. When the second cavity wall 300 and the first cavity wall 200 are closed relative to each other, the end of the discharge screw 600 away from the first cavity wall 200 is located inside the discharge component 500, and the discharge screw 600 can rotate relative to the discharge component 500. That is, during discharge, by rotating the discharge screw 600, the product can be moved out of the mixing space 110 along the axial direction of the discharge component 500 under the drive of the discharge screw 600.

[0099] In the illustrated embodiment, the front plate 310 is provided with a discharge port. The discharge member 500 is connected to the discharge port so that the product within the mixing space 110 can enter the discharge member 500 through the discharge port, thereby facilitating discharge. The back plate 210 is rotatably equipped with a discharge screw 600. When the second cavity wall 300 is closed relative to the first cavity wall 200, the discharge screw 600 partially extends into the discharge member 500. During discharge, the discharge screw 600 rotates under the drive of the drive member 410 to discharge the product within the mixing space 110. In some embodiments, the rotational speed of the discharge screw 600 may be different from the rotational speed of the rotating member 420 of the mixing structure 400. This arrangement facilitates discharge.

[0100] Furthermore, in some embodiments, such as Figures 1-4 The inner cavity wall 320 is provided with at least one protective sleeve 330. The first cavity wall 200 is provided with a corresponding wire passage hole 212. The protective sleeve 330 is configured to cooperate with the wire passage hole 212. The protective sleeve 330 is provided with a conductive space. The conductive space can accommodate wires or water pipes, etc. A through hole can be opened on the side of the protective sleeve 330 away from the front panel 310. The through hole communicates with the conductive space to facilitate the entry of wires or water pipes into the conductive space.

[0101] In the illustrated embodiment, three protective sleeves 330 are provided, respectively located at any three apex corners or near the apex corners of the inner cavity wall 320 near the back plate 210. The back plate 210 is provided with corresponding wire passage holes 212. The front plate 310 is provided with a cooling interlayer, and the conductive spaces within two of the protective sleeves 330 can pass through water pipes. One water pipe is an inlet pipe, and the other is an outlet pipe. This arrangement allows cooling water to flow into the cooling interlayer. The conductive space within the other protective sleeve 330 can pass through an electrical wire, enabling power to the corresponding device.

[0102] After the internal mixing of the previous product is completed, the aforementioned internal mixing device can be disassembled from the connecting piece 250 and the second section 223, and from the fastener 802 and the front plate 310, allowing the outer plate 220 to rotate relative to the back plate 210, thus releasing the locking state between the first cavity wall 200 and the second cavity wall 300. Pulling the second cavity wall 300 separates the front plate 310 and the inner cavity wall 320 (connected to the discharge piece 500) from the back plate 210. The discharge screw 600 is then separated from the discharge piece 500. The connecting bushing 431 is disassembled from the drive piece 410 to facilitate the disassembly of the rotating piece 420. After cleaning, the first cavity wall 200 and the second cavity wall 300 are connected, forming a mixing space 110 for internal mixing. Because the cleaning process is thorough, it reduces the risk of product quality degradation due to mixing.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
