[0035] For the convenience of understanding the present utility model, the specific embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings of the specification.

[0036] Unless otherwise specified or defined, the "first, second..." used herein is only for distinguishing names and does not represent a specific quantity or order.

[0037] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] It should be noted that "fixed to" and "connected to" herein may be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0039] In view of the problems of efficiency and personnel health caused by manually switching pipelines, manually aligning and opening / closing pipelines and equipment in the production and processing scenarios that require the use of powder, the utility model provides a multi-position pipeline rotary blanking device. The multi-position cylinder drives the first gear to rotate, the first gear drives the second gear to rotate, so that the first pipeline rotates, and then drives the second pipeline to rotate to dock with the corresponding equipment. When docking, a lifting platform is used to realize the automatic connection between the third pipeline in the lifting platform and the second pipeline. It can realize the automatic switching connection between the blanking pipeline and each equipment.

[0040] Reference Figure 1 and Figure 2 For this embodiment, the multi-position pipeline rotary blanking device mainly includes a material tray 10, a rotary mechanism 20 and a first pipeline 30 installed on the material tray 10, a second pipeline 40 connected to the first pipeline 30, and a lifting platform 50. The first pipeline 30 extends downward below the material tray 10 and upward above the rotary mechanism 20. The top end of the first pipeline 30 forms a blanking port 31 for connecting with a hopper 60. The rotary mechanism 20 rotates the first pipeline 30 around its axis, driving the second pipeline 40 to rotate, so that the second pipeline 40 can be connected to different homogenizer devices located around the lower part of the material tray 10. The lifting platform 50 is used to connect with a storage tank. A third pipeline 51 is provided in the lifting platform 50. When docking, the lifting platform 50 drives the third pipeline 51 to move upward to the first position, and the second pipeline 40 communicates with the third pipeline 51. The powder enters the homogenizer device from the hopper 60 via the first pipeline 30, the second pipeline 40 and the third pipeline 51, thus realizing the connection between the pipeline and the homogenizer device. If the current homogenizer device has completed feeding, the lifting platform 50 drives the third pipeline 51 to move downward to the second position, and the second pipeline 40 is disengaged from the third pipeline 51. Then the rotary mechanism 20 can rotate to the next position to connect with another homogenizer device.

[0041] Specifically, as Figure 3 and Figure 4 shown, the rotary mechanism 20 includes a multi-position cylinder 21, a first gear 22 and a second gear 23 that are meshed with each other. The material tray 10 is a box body with an open top. The multi-position cylinder 21 is installed in the material tray. The top end of the multi-position cylinder 21 is installed with the first gear 22. The second gear 23 is installed on the material tray 10 and can rotate around its own axis under the drive of the first gear 22.

[0042] The first pipeline 30 is fixed on the second gear 23, and the top end extends above the second gear 23 to form a blanking port 31. The first pipeline 30 penetrates through the material tray 10 and the second gear 23 and extends downward below the material tray 10. When the second gear 23 rotates, the first pipeline 30 rotates together with the second gear 23.

[0043] In this embodiment, the multi-position cylinder 21 is a three-position cylinder. The three-position cylinder has three working positions, usually including "extended", "retracted" and "intermediate position" (or holding position). The structure for the three-position cylinder to drive the first gear 22 to rotate is not limited and is a conventional technical means in the art. For example, the first gear 22 is connected to the piston rod in the three-position cylinder to drive the first gear 22 to rotate, or the piston is used to push the rack to drive the first gear 22 to rotate, which will not be elaborated here. Since the three-position cylinder has three working positions, correspondingly, the first gear 22 has three rotational positions, the first pipe 30 has three rotational angles, and the second pipe 40 also has three angular positions, and can be switched and connected between three homogenizer devices. It should be noted that the multi-position cylinder is not limited to a three-position cylinder, and can also be a two-position cylinder or a cylinder with more positions, etc.

[0044] One end of the second pipe 40 is connected to the end of the first pipe 30 adjacent to the material tray 10, and the other end is connected to the third pipe 51 in the connected state and is disengaged from the third pipe 51 in the disconnected state. The specific shape of the second pipe 40 is not limited. In this embodiment, the second pipe 40 includes two straight pipes 41 and an inclined pipe 42 in the middle. When the second pipe 40 is rotated to be connected to the homogenizer device in the intermediate position, as Figure 1 shown, the second pipe 40 presents as a vertical pipe; when the second pipe 40 is rotated to be connected to the homogenizer device in the left position or the right position, as Figure 2 shown, the second pipe 40 presents as a bent pipe.

[0045] In another embodiment, as Figure 5 and Figure 6 shown, the second pipe 40 includes a main pipe 43 and several sub-pipes 44. One end of the main pipe 43 is connected to the end of the first pipe 30 extending out of the material tray 10, and the other end is connected to the sub-pipe 44. A switching device 45 is also provided at the connection between the main pipe 43 and the sub-pipe 44. In this embodiment, the second pipe 40 can be physically connected to multiple homogenizer devices at the same time, and then the powder flow direction is controlled by the switching device 45 to different homogenizer devices, realizing soft switching between two homogenizer devices with one physical connection, and improving the switching efficiency. Specifically, the sub-pipe 44 includes two parts: an inclined pipe 441 and a straight pipe 442. The straight pipe 442 is used to communicate with or disengage from the third pipe 51. The inclined pipe 441 is connected to the main pipe 43 and forms a certain angle with the main pipe 43.

[0046] Inside the lifting platform 50, there are multiple lifting cylinders 52 and hoses 53. The lifting cylinders 52 are arranged around the hoses 53. When the lifting cylinders 52 rise or fall, they can stretch or compress the hoses 53. In this embodiment, the top ends of the lifting cylinders 52 and the top ends of the hoses 53 are connected to the first panel 54, and the bottom ends of the lifting cylinders 52 and the bottom ends of the hoses 53 are connected to the second panel 55. Above the first panel 54, there is also an open pipe 56, which is connected to the hose 53 to form a third pipe 51 that penetrates the lifting platform 50. The above-mentioned first pipe 30, second pipe 40, and third pipe 51 together form a feeding pipe.

[0047] In this embodiment, there are two lifting cylinders 52, which are respectively arranged on the left and right sides of the hose 53, and are used to lift the height of the open pipe 56 so that the open pipe 56 can be engaged or disengaged with the second pipe 40. Specifically, when the lifting platform 50 rises, the open pipe 56 moves upward until it is connected to the second pipe 40, and the feeding pipe is connected to the homogenizer equipment; when the lifting platform 50 descends, the top end of the open pipe 56 disengages from the second pipe 40, and the feeding pipe is disconnected from the homogenizer equipment.

[0048] In order to make the open pipe 56 easier to connect with the second pipe 40, in the direction towards the lifting platform 50, the diameter of the end of the open pipe 56 gradually decreases. That is, the end of the open pipe 56 is designed as a frustum of a cone with a larger diameter at the upper part and a smaller diameter at the lower part. During docking, even if the open pipe 56 has a slight deviation from the vertical direction, it can still be successfully connected to the second pipe 40.

[0049] In some embodiments, a soft rubber 57 is also attached to the inner wall of the end of the open pipe 56 to prevent the second pipe 40 and the open pipe 56 from colliding hard.

[0050] In some embodiments, in order to make the docking between the second pipe 40 and the open pipe 56 more flexible and buffered, a pneumatic butterfly valve 46 and an elastic mechanism 47 are also provided on the second pipe 40. The pneumatic butterfly valve 46 is arranged near the end of the second pipe 40, and the elastic mechanism 47 is arranged above the pneumatic butterfly valve 46. The impact force generated when the second pipe 40 and the open pipe 56 are docked is offset by the pneumatic butterfly valve 46 and the elastic mechanism 47. In one example, the elastic mechanism 47 includes a spring upper seat 471, a spring lower seat 472, and an elastic member 473. The spring upper seat 471 is located above the spring lower seat 472, and both the spring upper seat 471 and the spring lower seat 472 are clamped on the second pipe 40. The elastic member 473 is arranged around the second pipe 40 and is located between the spring upper seat 471 and the spring lower seat 472. When an impact force is generated during the docking of the second pipe 40 and the third pipe 51, the elastic member 473 vibrates between the spring upper seat 471 and the spring lower seat 472 to absorb the impact force.

[0051] In some embodiments, the multi-position pipe rotary blanking device further includes a hopper 60, and the hopper 60 is connected to one end of the first pipe 30 adjacent to the second gear 23, that is, the hopper 60 is installed on the blanking port 31 of the first pipe 30.

[0052] In use, the connection between the pipe and the homogenizer equipment can be controlled according to the height of the equipment level gauge and the length of time. First, the bucket elevator lifts the material to the hopper and drops it into the first pipe. The rotating mechanism controls the second pipe and the third pipe to be interlocked according to the level gauge in the homogenizer. According to the material high-level feedback control unit, the blanking stops when the high level is leveled, the lifting cylinder descends, and the feeding port of the homogenizer automatically closes. After the first homogenization equipment finishes feeding, the rotating mechanism rotates the second pipe above the feeding port of the second homogenizer. At this time, the lifting cylinder of the second homogenizer rises and holds against the discharge port of the second pipe to achieve feeding to the second homogenizer.

[0053] It should be noted that although the multi-position pipe rotary blanking device in this embodiment is used for handling the blanking of powders, it is not limited to powders and can also achieve the blanking of liquids or solids.

[0054] In summary, through the rotating mechanism composed of a multi-position cylinder, a first gear, and a second gear, the second pipe is driven to rotate so as to be docked with the corresponding equipment. And during docking, the lifting platform is used to automatically realize the connection between the third pipe and the second pipe in the lifting platform. Therefore, the automatic switching connection between the blanking pipe and each equipment can be achieved. It can reduce costs, ensure process production capacity, and achieve the effect of cost reduction and efficiency improvement.

[0055] The above embodiments are not an exhaustive list based on the present utility model. In addition, there may be multiple other embodiments not listed. Any replacement and improvement made without violating the concept of the present utility model fall within the protection scope of the present utility model.
