DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0026] As shown in the figure, the present invention includes: a frame, a hopper 1, a driving mechanism, a stirring barrel 6, a feeding device and a discharging device 10. The hopper, the feeding device, the driving mechanism and the discharging device are fixed to the frame in sequence from top to bottom. The frame in this embodiment is divided into an outer upper frame 3 and an outer lower frame 9. The upper end of the outer upper frame is fixedly connected to a material support 2. The hopper is fixedly connected to the material support, and multiple hoppers are arranged around it, so that a variety of materials can be mixed to meet a variety of mixing requirements. The upper end of the feeding device is arranged below the hopper, and the lower end of the feeding device is provided with a feeding port 17, the upper end of the discharging device is provided with a discharge port 8, and the lower end is provided with a discharging port 11.

[0027] The driving mechanism includes a driving motor 21, a fixed bevel gear 4, a swivel jacket 5 and a rotating bevel gear 7. The driving motor is fixedly connected to the frame. The rotating jacket is fixedly connected to a jacket rotating shaft for rotationally connecting with the frame. The jacket rotating shaft includes a jacket driving shaft 51 and a jacket driven shaft 52 arranged at both ends of the rotating jacket. The jacket driving shaft and the jacket driven shaft are rotationally connected to the frame through jacket bearings 19 respectively. The jacket rotating shaft and the driving motor are driven by gears. In this embodiment, a driving gear 22 is fixedly connected to the driving motor, and a driven gear 20 is fixedly connected to the jacket rotating shaft. The driving gear and the driven gear are meshed with each other. The fixed bevel gear is coaxially fixed to the jacket driving shaft. The mixing barrel is arranged in the swivel jacket. A mixing barrel rotating shaft for rotationally connecting with the swivel jacket is fixedly connected to the mixing barrel. The mixing barrel rotating shaft includes a mixing barrel driving shaft 51 and a mixing barrel driven shaft 52 arranged at both ends of the mixing barrel. The mixing barrel driving shaft and the driven gear 20 are rotationally connected to the frame through jacket bearings 19 respectively. The mixing barrel rotating shaft and the driving motor are transmission by gears. In this embodiment, a driving gear 22 is fixedly connected to the driving motor, and a driven gear 20 is fixedly connected to the jacket rotating shaft. The driving gear and the driven gear are meshed with each other. The fixed bevel gear is coaxially fixed to the jacket driving shaft. The mixing barrel is arranged in the swivel jacket. A mixing barrel rotating shaft for rotationally connecting with the swivel jacket is fixedly connected to the mixing barrel. The mixing barrel rotating shaft includes a mixing barrel driving shaft 51 and a mixing barrel driven shaft 52 arranged at both ends of the mixing barrel. The mixing barrel driving shaft 63 and the mixing shaft driven shaft 62 are on the side, and the rotating outer shell is provided with a large outer shell port 53 corresponding to the mixing barrel driving shaft and a small outer shell port 54 corresponding to the mixing barrel driven shaft. The mixing barrel driving shaft and the small outer shell port are rotatably connected through the driving shaft bearing 13, and the mixing barrel driven shaft and the large outer shell port are rotatably connected through the driven shaft bearing 15. The rotating bevel gear is coaxially fixed to the mixing barrel rotating shaft, and the rotating bevel gear and the fixed bevel gear are meshed with each other and arranged vertically. The rotating bevel gear and the fixed bevel gear can also be replaced by friction wheels and other devices. The driving motor drives the fixed bevel gear and the rotating outer shell to rotate through gear transmission, and the rotating bevel gear meshed with the fixed bevel gear drives the mixing barrel rotating shaft to make the mixing barrel rotate, thereby realizing the three-dimensional rotation of the mixing barrel. The mixing barrel opening in this embodiment is fixedly connected with a material pocket 61 to avoid material accumulation at the edge.

[0028] Preferably, a sealing device 23 is provided in the mixing barrel, and a feeding unsealing device 18 and a discharging unsealing device 12 corresponding to the sealing device are provided in the feeding device and the discharging device. The feeding unsealing device and the discharging unsealing device in this embodiment both include a driver and a driving rod that reciprocates through the driver. When the mixing barrel rotates to a corresponding position, the corresponding unsealing device unlocks the sealing device, thereby allowing materials to be fed in and out, realizing the automation of the loading and unloading processes, saving labor costs, and improving safety.

[0029] Preferably, the sealing device includes an outer sleeve 16, a movable rod and a sealing end 14, the outer sleeve is fixedly connected to the mixing barrel, the movable rod is inserted into the outer sleeve, one end of the movable rod close to the mixing barrel is fixedly connected to the sealing end, and the other end is provided with a limiting portion, and a return spring 161 is sleeved on the movable rod between the limiting portion and the outer sleeve, and the sealing end is conical.

[0030] The working principle and workflow of the three-dimensional mixing mechanism in this embodiment are as follows: install the various parts in the manner shown in the figure, and in the initial state, the rotation of the driving motor 21 satisfies the feeding position relationship, such as Figure 1As shown, at this time, the material pocket 61 of the mixing barrel 6 is placed opposite to the feed port 17, which is the loading position. Different types of materials are placed in the hopper 1 respectively, and the sealing device 23 is moved a certain distance along the driven shaft 62 of the mixing barrel into the mixing barrel 6 by pushing the material unlocking device 18 downward. At this time, the material in the hopper 1 flows into the mixing barrel 6 through the material pocket 61 along the feed port 17. When the material is loaded, the material unlocking device 18 returns to the initial position. At the same time, the sealing device 23 returns to the original position through the reset spring in the outer sleeve 16 to ensure that the mixing barrel 6 has a certain sealing performance. At this time, the loading work is completed. This process is called the loading stage;

[0031] The driving motor 21 rotates to drive the driving gear 22 connected thereto to rotate, and the driving gear 22 meshes with the driven gear 20, thereby driving the driven gear 20 to rotate. Since the outer jacket driving shaft 51 on the swivel outer jacket 5 is fixedly connected to the driven gear 20, the rotation of the driven gear 20 drives the swivel outer jacket 5 to rotate. At this time, the swivel outer jacket 5 rotates around the outer jacket driving shaft 51 and the outer jacket driven shaft 52. Since the mixing barrel 6 is rotatably connected to the swivel outer jacket 5, the mixing barrel 5 also rotates with the rotation of the swivel outer jacket 6. The mixing barrel 6 is rotated; a rotating bevel gear 7 is installed on the mixing barrel driving shaft 63 of the mixing barrel 6, so the rotating bevel gear 7 rotates with the mixing barrel 6 at the same time. Since the rotating bevel gear 7 and the fixed bevel gear 4 are meshed with each other, the rotating bevel gear 7 rotates in the same direction as the rotating outer jacket 5 and rotates along the fixed bevel gear 4. Since the mixing barrel 6 and the rotating bevel gear 7 are fixedly connected, the mixing barrel 6 revolves with the rotating outer jacket 5 and rotates with the rotating bevel gear 7. That is, the mixing barrel rotates in three dimensions at this time to evenly mix multiple materials. This process is called the mixing stage;

[0032] After the materials are mixed evenly, the mixing barrel 6 is rotated to the unloading position by the rotation of the driving motor 21. Figure 2 As shown, at this time, the material pocket 61 of the mixing barrel 6 is placed opposite to the material discharge port 8, and this position is the unloading position. The sealing device 23 is moved a certain distance along the driven shaft 62 of the mixing barrel into the mixing barrel 6 by pushing upward through the material discharge unlocking device 12. At this time, the material in the mixing barrel 6 will flow downward along the sealing end 14, and the material will flow along the material pocket 61, the material discharge port 8, and the material discharge device 10 to the material discharge port 11 in sequence until it flows out from the material discharge port 11. When all the material flows out, the material discharge unlocking device 12 returns to the initial position. At the same time, the sealing device 23 is returned to its original position through the reset spring in the outer sleeve 16, and the unloading work is completed. This process is called the unloading stage;

[0033] If mixing is performed multiple times, the loading stage, the mixing stage and the unloading stage are repeated in sequence after the unloading stage is completed until the loading stage.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
