The current mainstream two-dimensional motion mixer mainly consists of a rotating drum, a swing frame, and a frame. The rotating drum is installed on the swing frame and is supported by four rollers and axially limited by two blocking wheels. Among the four supporting rollers, two transmission wheels are driven by a rotating power system to drive the rotating drum to rotate around its own axis on the swing frame. The swing frame is driven by a set of crank and swing rod mechanisms installed on the frame and connected to the swing frame, so that the swing of the swing frame on the frame can be controlled. Further, the rotating drum is connected to the frame in rotation during rotation, thereby increasing the mixing efficiency of the materials inside the rotating drum.
[0003] In the traditional two-dimensional motion mixer, the user needs to sequentially deliver different raw materials into the two-dimensional motion mixer when adding raw materials to the two-dimensional motion mixer. However, the raw materials may be layered at this time, and it is difficult to quickly mix the layered raw materials during the rotation and swing of the two-dimensional motion mixer, the mixing uniformity is low, and the mixing quality is affected. SUMMARY
[0004] In view of the problems existing in the prior art, the application provides a two-dimensional motion mixer, which comprises a rack, a swing frame swing-connected to the rack, a rotating drum rotationally connected to the swing frame, and a feeding port at one end of the rotating drum, wherein an internal stirring device is arranged in the rotating drum, the stirring device comprises an auxiliary mixing bin which is sealingly and rotationally connected to the inner wall of the rotating drum and divides the inside of the rotating drum into a coarse mixing area and a fine mixing area in the auxiliary mixing bin, and the fine mixing area and the coarse mixing area are in communication with each other; a driving motor is further arranged on one side of the auxiliary mixing bin, the driving motor is fixed in the rotating drum and drives the auxiliary mixing bin to rotate coaxially with the rotating drum; at least one roller cylinder is further arranged in the rotating drum, one end of the roller cylinder is open and penetrates into the auxiliary mixing bin, and a plurality of feeding holes are formed in the circumferential side of each roller cylinder; a rotating shaft is coaxially arranged in each roller cylinder and rotationally connected to the auxiliary mixing bin; a helical blade is arranged along the length direction of the rotating shaft and fixed to the circumferential side of each rotating shaft; and a driven assembly is arranged in the rotating drum and used for driving each rotating shaft to rotate when the auxiliary mixing bin rotates. Through the above technical features, the material is accumulated in the mixing area of the rotating drum, the auxiliary mixing bin is driven to rotate by the driving motor, the roller cylinder rotates to not only stir the material but also extrude and refine the material, the feeding holes are arranged to drive the material to enter the roller cylinder, the helical blade rotates to drive part of the material to be transported to the fine mixing area of the auxiliary mixing bin, the fine mixing area has a large space and relatively less material, the mixing efficiency of the material is improved, the fine mixing area and the coarse mixing area are in communication, and the material is discharged, so that the mixing efficiency of the whole material is improved.
[0005] In some embodiments, the driven assembly comprises a first annular rack coaxially fixed to the inner wall of the rotating drum and a first gear coaxially fixed to the circumferential side of each rotating shaft, and the first annular rack and the first gear are in meshing engagement. Thus, the first gear and the first annular rack are in meshing engagement when each rotating shaft follows the displacement of the auxiliary mixing bin during the rotation of the auxiliary mixing bin driven by the driving motor, so that the helical blade rotates, the functions of mixing, transporting the material on the helical blade and the driving motor are simultaneously realized, and the energy saving and environmental protection are improved.
[0006] In some embodiments, the auxiliary mixing bin is provided with a stirring mechanism, the stirring mechanism comprises a second annular rack which is coaxially arranged in the auxiliary mixing bin and sealingly and rotationally connected to the inner wall of the auxiliary mixing bin. The second gear is arranged in the auxiliary mixing bin and is in meshing engagement with the second annular rack; the second motor is fixed outside the auxiliary mixing bin, and the output shaft thereof is coaxially fixed to the second gear; and the tab is fixed to one side of the second annular rack and extends along the height direction of the auxiliary mixing bin. Thus, since the two-dimensional motion mixer is in a horizontal stirring state, the second annular rack is driven by the second gear, and in the process of its own rotation, the rack of the second annular rack plays a role in auxiliary stirring of the material. With the rotation of the second annular rack, the tab is displaced, thereby playing a role in mixing and stirring of the material in the auxiliary mixing bin.
[0007] In some embodiments, a plurality of mixing openings are formed in the side of the auxiliary mixing bin facing the drum feed port, and the mixing openings are located in the corresponding area of each tab; and each tab is further fixed with a baffle for sealing the mixing opening. Thus, in cooperation with the rotating position of the drum, with the rotation of the tab, the material in the fine mixing zone is accelerated to flow, and at the same time, the mixing opening is opened, accelerating the transportation of the material from the fine mixing zone to the coarse mixing zone, which helps to discharge the material in the fine mixing zone and increases the scattering of the material during the discharging process, thereby improving the mixing efficiency of the material in the fine mixing zone and the material in the coarse mixing zone.
[0008] In some embodiments, a first motor is coaxially fixed to the side of the auxiliary mixing bin away from the drum feed port, the output shaft of the first motor is coaxially fixed to an extension shaft, and the end of the extension shaft is located in the mixing zone of the drum, and a plurality of turbulence tabs are arranged on the circumferential side of the extension shaft. Thus, in the process of tab rotation and material stirring, the material in the fine mixing zone scatters into the coarse mixing zone, and with the rotation of the turbulence tabs, the surrounding air flows, causing the material discharged from the mixing opening to be disturbed by the air flow, thereby accelerating the dispersion efficiency.
[0009] In some embodiments, each of the turbulence tabs is parallel to the side of the auxiliary mixing bin where the mixing opening is formed. Thus, the resistance of the turbulence tabs to the material in the coarse mixing zone is reduced, the contact range with the material in the fine mixing zone is increased, and the driving pressure of the first motor is also reduced, thereby ensuring the stirring efficiency of the material in the fine mixing zone.
[0010] In some embodiments, each of the roller cylinders is provided with a vibration hole-clearing device at the open end, and the vibration hole-clearing device comprises a cover fixed to the end of each of the roller cylinders; a spring fixed to the end of the roller cylinder that is not sealed; and further comprising a resilient ball fixed to the other end of the spring. Thus, when the roller cylinder hard contacts the surface of the material, the rotation speed of the roller cylinder is slowed down, the resilient ball hits the inner wall of the cover, and further drives the roller cylinder to produce slight vibration, which easily clears the blocked material of the feeding hole of the roller cylinder and accelerates the flow of the material.
[0011] In some embodiments, a plurality of elastic sheets are arranged in each cover, one end of the elastic sheet is fixed to the inner wall of the cover, and the other end is located on the swing path of the elastic ball. In this way, the vibration time of the roller cylinder is prolonged, and the efficiency of the feeding hole of the roller cylinder is improved.
[0012] It should be understood that the content described in the summary section is not intended to limit the key or important features of the embodiments of the present disclosure, nor to limit the scope of the present disclosure. Other features of the present disclosure will become apparent from the following description. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0015] In the following, preferred embodiments (or implementation manners) of the present application will be described in detail with reference to the accompanying drawings.
[0016] In the following, a two-dimensional motion mixer according to the present application will be described with reference to Figures 1-6
[0017] Figure 1 The overall structure diagram of a two-dimensional motion mixer is shown in the embodiment of the present application. Referring to Figure 1 As shown in the figure, the two-dimensional motion mixer provided in the embodiment includes a base frame 11, a swing frame 12 rotatably connected above the base frame 11, and a rotating drum 13 installed above the swing frame 12. The base frame 11 is provided with a crank swing lever mechanism, and the swing frame 12 is connected to the base frame 11 through the crank swing lever mechanism, so as to realize the reciprocating swing of the swing frame 12 on the base frame 11. The swing frame 12 supports the rotating drum 13 through a plurality of rollers, and limits the axial position of the rotating drum 13 through the blocking wheels arranged on both sides. The swing frame 12 is provided with a rotating power system, which controls two rollers to realize the rotation of the rotating drum 13 around the axial direction of the rotating drum 13 on the swing frame 12. The crank swing lever mechanism, the rollers, and the rotating power system are all prior art, and will not be described here.
[0018] Figure 2 The internal structure diagram of the rotating drum in the two-dimensional motion mixer is shown in the embodiment of the present application. Referring to Figure 2 As shown in the figure, the rotating drum 13 is a cylindrical structure with a large middle part and small ends. One end is a feeding port 131 for feeding and discharging, and the other end is a maintenance port 132 for maintaining and repairing the internal stirring structure. In order to improve the stirring efficiency of the material in the rotating drum 13, the inside is divided into zones. An auxiliary mixing bin 2 is arranged in the middle region. The auxiliary mixing bin 2 is coaxially arranged with the rotating drum 13, and the side of the auxiliary mixing bin 2 is sealingly and rotatably connected with the inner wall of the rotating drum 13. This forms a fine mixing zone 133 inside the auxiliary mixing bin 2 and a coarse mixing zone 134 located in the direction of the feeding port 131 of the rotating drum 13. An electric motor 21 is arranged on the side of the auxiliary mixing bin 2 facing the maintenance port 132. The electric motor 21 is fixed inside the rotating drum 13 and coaxially arranged with the rotating drum 13. The output shaft of the electric motor 21 is fixed with the auxiliary mixing bin 2, so that the electric motor 21 can drive the auxiliary mixing bin 2 to rotate around its axial direction when the electric motor 21 works.
[0019] In some embodiments, the auxiliary mixing bin 2 can be a cylindrical structure with a circular cross-section, which can make full use of the space inside the rotating drum 13, increase the amount of material entering the auxiliary mixing bin 2, ensure the capacity of the material being stirred at the same time, and improve the mixing efficiency. The auxiliary mixing bin 2 can also be a cylindrical structure with a polygonal cross-section. Since the side of the auxiliary mixing bin 2 is composed of multiple planes, the vibration effect on the material is improved during the rotation of the auxiliary mixing bin 2, which indirectly improves the mixing effect of the material. In order to maximize the utilization of the space inside the rotating drum 13, the auxiliary mixing bin 2 is preferably a polygonal structure with a cross-section close to a circle. This ensures the utilization of the space inside the rotating drum 13 and increases the vibration frequency of the material, thereby improving the overall mixing efficiency of the material.
[0020] Figure 3 A cross-sectional view of the internal structure of the rotating drum 13 of a two-dimensional motion mixer according to an embodiment of the present application is shown. Referring to Figure 3 As shown, the auxiliary mixing bin 2 is provided with a roller cylinder 3 on the side facing the inlet 131 of the rotating drum 13. One end of the roller cylinder 3 is open, and the other end is closed. The roller cylinder 3 is arranged along the axial direction of the rotating drum 13, and the open end of the roller cylinder 3 is arranged in the auxiliary mixing bin 2 and communicates with the internal space of the auxiliary mixing bin 2. A plurality of feeding holes 31 are uniformly arranged on the side of the roller cylinder 3. During the rotation of the auxiliary mixing bin 2, the roller cylinder 3 contacts the surface of the material and turns over part of the material. Part of the material enters the interior of the roller cylinder 3 through the feeding holes 31 of the roller cylinder 3, and enters the interior of the auxiliary mixing bin 2 along with the swinging of the rotating drum 13, thereby achieving the distribution of the material in the coarse mixing zone 134 and the fine mixing zone 133.
[0021] In some embodiments, the number of roller cylinders 3 is multiple. In this embodiment, the number of roller cylinders 3 is four. The roller cylinders 3 are fixed to the edge region of the end face of the auxiliary mixing bin 2. Due to the side-lying rotation of the rotating drum 13, the material inside the rotating drum 13 is concentrated on the side of the rotating drum 13. Therefore, the roller cylinders 3 arranged near the side of the rotating drum 13 increase the contact range with the material, thereby improving the mixing efficiency of the material.
[0022] Each roller cylinder 3 is provided with a rotating shaft 32 coaxial with the roller cylinder 3, and the other end of the rotating shaft 32 penetrates out of the other side of the auxiliary mixing bin 2 and is sealingly and rotatably connected with the inner wall of the auxiliary mixing bin 2. The region inside the roller cylinder 3 of each rotating shaft 32 is provided with a spiral blade 33 fixed to the circumferential side of the rotating shaft 32 along the length direction of the rotating shaft 32, and the edge of the spiral blade 33 leaves a gap of 5-8 mm with the inner wall of the roller cylinder 3, so that the contact between the spiral blade 33 and the inner wall of the roller cylinder 3 is reduced during rotation, and at the same time, the conveying efficiency of most of the materials entering the roller cylinder 3 is met. The materials entering the inside of the roller cylinder 3 are conveyed to the auxiliary mixing bin 2 by the rotation of the spiral blade 33.
[0023] Figure 4 A structure diagram of a driven assembly 4 in a two-dimensional motion mixer according to the embodiment of the application is shown. Referring to Figure 4 As shown, the ends of each rotating shaft 32 are collectively provided with a driven assembly 4 for driving each rotating shaft 32 to rotate. The driven assembly 4 includes a first annular gear rack 41 located on the side of the auxiliary mixing bin 2 facing the access opening 132 of the rotating drum 13, and the first annular gear rack 41 is coaxially fixed with the rotating drum 13. The end of each rotating shaft 32 is coaxially fixed with a first gear 42, and each first gear 42 is in meshing engagement with the first annular gear rack 41, so that during the rotation of the auxiliary mixing bin 2 driven by the main motor 21, the rotating shaft 32 rotates with the auxiliary mixing bin 2, and the first gear 42 is in meshing engagement with the first annular gear rack 41, further driving the spiral blade 33 to rotate around each rotating shaft 32, thereby realizing the conveying effect of the materials entering the inside of the roller cylinder 3.
[0024] In order to accelerate the mixing efficiency of the materials in the auxiliary mixing bin 2, a stirring mechanism 5 is further provided in the auxiliary mixing bin 2, Figure 5 A structure diagram of a stirring mechanism 5 in a two-dimensional motion mixer according to the embodiment of the application is shown. Referring to Figure 5 As shown, the stirring mechanism 5 includes a second motor 51 provided on the side of the auxiliary mixing bin 2 facing the access opening 132 of the rotating drum 13, and the second motor 51 is located at the edge region of the auxiliary mixing bin 2, and the output shaft of the second motor 51 penetrates into the auxiliary mixing bin 2 and is coaxially fixed with a second gear 52. A second annular gear rack 53 is coaxially provided around the circumferential side of the auxiliary mixing bin 2 in the auxiliary mixing bin 2, and the second annular gear rack 53 is sealingly and rotatably connected with the inner wall of the auxiliary mixing bin 2 and is in meshing engagement with the second gear 52. A plurality of paddles 54 are vertically arranged on one side of the second annular gear rack 53 along the height direction of the auxiliary mixing bin 2, so that under the driving of the second motor 51, the materials in the auxiliary mixing bin 2 are stirred, thereby greatly improving the contact area and stirring effect of the materials.
[0025] The auxiliary mixing bin 2 is provided with a plurality of mixing openings 22 at the bottom of the feeding opening 131 of the rotating drum 13, the mixing openings 22 are located in the corresponding area of each paddle 54, and each paddle 54 is further fixed with a baffle 55 on the side facing the mixing opening 22, which blocks the mixing opening 22 in the corresponding area of the paddle 54. Therefore, when the material is initially mixed, the paddle 54 is locked in the area of the mixing opening 22 under the limitation of the second motor 51, so that the baffle 55 blocks the mixing opening 22, and if the material wants to enter the auxiliary mixing bin 2, it can only be transported into the auxiliary mixing bin 2 through the roller pressing cylinder 3 by the rotation of the spiral blade 33.
[0026] Moreover, when the stirring mechanism 5 is working, the rotating drum 13 needs to be rotated to a state where the feeding opening 131 is inclined to the ground, at this time, the material in the auxiliary mixing bin 2 is concentrated on the side of the auxiliary mixing bin 2, and the second motor 51 needs to be rotated to the top area, so that the second gear 52 is disengaged from the buried material, and most of the material will also be disengaged from the slot of the second annular gear rack 53 under the action of gravity, and will not affect the normal engagement of the second gear 52 and the second annular gear rack 53. With the rotation of the second annular gear rack 53, it not only drives the displacement of the paddle 54, but also the rack itself plays a role in stirring the material. With the support and stirring of the paddle 54, the material is stirred from the bottom to the top area and falls along the side of the auxiliary mixing bin 2 towards the feeding opening 131 of the rotating drum 13, the material will fall into the rough mixing area 134 of the rotating drum 13 through the area of the mixing opening 22, and the mixing efficiency is further improved during the falling process of the material.
[0027] In order to improve the mixing efficiency of the material, a first motor 61 is coaxially fixed to the side of the auxiliary mixing bin 2 facing the access opening 132, the output shaft of the first motor 61 penetrates into the auxiliary mixing bin 2 and is coaxially fixed with an extension shaft 62, the distal end of the extension shaft 62 penetrates through the auxiliary mixing bin 2 and is located inside the rotating drum 13, and a plurality of turbulence vanes 63 are fixed to the side of the extension shaft 62. During the rotation of the first motor 61, the turbulence vanes 63 are driven to rotate, and the air on the side of the turbulence vanes 63 flows faster, the material in the auxiliary mixing bin 2 enters the rough mixing area 134 of the rotating drum 13 through the mixing opening 22 and contacts with the flowing air, thereby accelerating the scattering effect of the material and further improving the mixing efficiency of the material.
[0028] Furthermore, each baffle 63 is parallel to the side of the auxiliary mixing chamber 2 with the mixing port 22. This ensures that when the baffle 63 comes into contact with the material in the coarse mixing zone 134, the contact is tangential, resulting in less resistance and reducing the driving pressure on the first motor 61. It also greatly increases the contact range with the material falling in the air, allowing the baffle 63 to turbulently mix the material flowing in the air. Similarly, it can also assist in stirring the material in the middle region in conjunction with the rotation of the roller cylinder 3.
[0029] Figure 6 A cross-sectional view of the end structure of the roller cylinder 3 in a two-dimensional motion mixer according to an embodiment of the present invention is shown. (See reference) Figure 6 As shown, to prevent material blockage in the feed hole 31 during roller pressing, each roller pressing cylinder 3 is equipped with a vibration pore-clearing device 7 at its sealed end. The vibration pore-clearing device 7 includes a cover 71, the edge of which is fixed to the end of the roller pressing cylinder 3. A spring 72 is installed inside the cover 71, one end of which is fixed to the end of the roller pressing cylinder 3, and the other end is fixed to an elastic ball 73. The stroke of the elastic ball 73 can satisfy the need to strike the inner wall of the cover 71. When the roller pressing cylinder 3 rotates and contacts the material in the coarse mixing zone 134, it will cause the spring 72 to undergo elastic deformation, thereby causing the elastic ball 73 to strike the inner wall of the cover 71 and causing the roller pressing cylinder 3 to vibrate. This can easily cause the material in the feed hole 31 area of the roller pressing cylinder 3 to disengage from the feed hole 31, improving the efficiency of material entering and exiting the feed hole 31.
[0030] Furthermore, in order to increase the vibration time of the roller press 3, multiple spring pieces 74 are provided on the inner wall of the cover 71 along its periphery. One end of the spring piece 74 is fixedly connected to the inner wall of the cover 71, and the other end extends towards the middle of the cover 71. When the spring 72 bends elastically, the elastic ball 73 will first contact the spring piece 74 and drive the spring piece 74 to vibrate, and drive all the spring pieces 74 on the periphery to vibrate, thereby prolonging the vibration time of the roller press 3 and reducing the risk of material getting stuck in the feed hole 31 of the roller press 3.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
