[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example

[0022] Reference Figures 1 to 4 , which is the first embodiment of the utility model, provides an automatic weighing and packaging machine, which includes a support rod 1, a frame 2 installed inside the support rod 1, a ferroboron finished product hopper 3 installed inside the frame 2, a conveyor belt scale 4 installed at the bottom of the ferroboron finished product hopper 3, and a hopper 5 installed at one end of the conveyor belt scale 4; the top of the hopper 5 is fixedly connected to the frame 3, a motor for driving the conveyor belt scale 4 is installed on one side, and an arc plate 6 is installed at the bottom of the hopper 5. The arc plates 6 are arranged in a circular array, and both sides of the bottom of the arc plates 6 are fixedly connected with connecting plates 7, and the connecting plates 7 are arranged in a U shape. Two groups of arc plates 6 are fixedly connected through the connecting plates 7 to form a packaging turntable. A moving wheel 8 is installed at the bottom of the connecting plate 7. The packaging turntable composed of the arc plates 6 can be rotated by the moving wheel 8, and each group of arc plates 6 represents a workstation angle. The arc plates 6 in a circular array can replace six workstation angles, thereby increasing the rest time of the staff. A conveyor belt (not shown in the figure) is also provided on one side of the packaging turntable, which can facilitate the transportation of the ferroboron material after packaging to the next workstation and reduce the workload of the staff.

[0023] The connecting plates 7 are arranged in a circular array, a connecting ring 11 is installed at the bottom of the arc plate 6, a connecting bolt 12 is fixedly connected inside the connecting ring 11, and both ends of the connecting bolt 12 are fixedly connected to the arc plate 6 and the connecting plate 7 respectively. The arc plate 6, the connecting plate 7 and the connecting ring 11 are fixedly connected through the connecting bolt 12, so that they can become a whole to facilitate the rotation of the arc plate 6.

[0024] The inner side of the arc plate 6 is rotatably connected to a shaft disk 9, and the bottom of the shaft disk 9 is fixedly connected to a reinforcing leg 10. The bottom of the shaft disk 9 passes through a connecting ring 11 and is rotatably connected to it, and the reinforcing leg 10 is in contact with the ground. At the same time, the bottom of the shaft disk 9 also passes through a driven gear 13 and is rotatably connected to it, so that the packaging turntable can rotate around the shaft disk 9, making it more stable when rotating. The top diameter of the shaft disk 9 is larger than the internal diameter of the packaging turntable to enhance the stability of the packaging turntable. The bottom of the reinforcing leg 10 is installed with staggered rubber plates to increase its friction with the ground and increase its stability.

[0025] The bottom of the connecting ring 11 is fixedly connected with a driven gear 13, the bottom of the arc plate 6 and the inner side of the moving wheel 8 is installed with a base 14, the surface of the base 14 is fixedly connected with a driving motor 15, the output end of the driving motor 15 is fixedly connected with a driving gear 16, the driving gear 16 is located on one side of the driven gear 13 and meshes with it, the base 14 is in contact with the ground, and bricks can be placed inside the base 14 to ensure the stability of the base 14, thereby avoiding the phenomenon of the driving motor 15 rotating. In addition, the bottom of the base 14 is vertically installed with equidistantly arranged rubber plates to increase its friction with the ground and keep it stable. By driving the driving gear 16 to drive the driven gear 13 to rotate the packaging turntable, the purpose of rotating a station angle after packaging a package of ferroboron material can be achieved, and the base 14 is located on one side of the reinforcing leg 10.

[0026] During use, when the ferroboron falls into the interior of the packaging belt through the hopper 5 and the packaging operation is completed, the driving motor 15 can be started to drive the driving gear 16 to rotate, and at the same time drive the driven gear 13 to rotate, and drive the connecting plate 7 and the arc plate 6 to rotate through the connecting ring 11, so that it can rotate around the shaft disc 9 through the moving wheel 8, so that another set of arc plates 6 is located at the bottom of the discharge port. In this way, it can be rotated by one station angle, and by accumulating six groups of station angles, the rest time of the staff can be increased, thereby reducing the work intensity of the staff, avoiding the waiting time required in the traditional packaging method, and also realizing rapid station conversion, improving production efficiency and material fluidity, shortening the production cycle, and achieving the purpose of automation. Example

[0027] Reference Figures 1 to 5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0028] An L-shaped plate 23 is fixedly connected to one side of the frame 2 and to both sides of the hopper 5 . A bearing plate 24 is fixedly connected to one end of the L-shaped plate 23 . The bearing plate 24 is L-shaped, and a motor 17 is installed on the outer side of the bearing plate 24 .

[0029] The inner side of the carrier plate 24 is rotatably connected with a rotating disk 18, the output end of the motor 17 extends to the inner side of the carrier plate 24 and is fixedly connected with the rotating disk 18, and the surface of the rotating disk 18 is movably connected with a driving rod 19. One end of the driving rod 19 is movably connected with a reciprocating rod 20, one end of the reciprocating rod 20 passes through the L-shaped plate 23 and is movably sleeved therewith, which can limit the reciprocating rod 20 so that it always maintains a horizontal reciprocating motion.

[0030] A knocking plate 21 is provided on the inner side of the L-shaped plate 23, one end of the reciprocating rod 20 extends to the inner side of the L-shaped plate 23 and is fixedly connected to the knocking plate 21, and rubber blocks 22 arranged equidistantly are installed on the surface of the knocking plate 21. The rubber blocks 22 are located on both sides of the hopper 5, and because they are made of rubber material, they will not actually damage the hopper 5 when knocked, and at the same time, the boron iron finished product inside the hopper 5 can quickly fall into the inside of the packaging bag, thereby achieving the purpose of preventing blockage.

[0031] During use, the ferroboron material will fall from the ferroboron finished product hopper 3 to the surface of the conveyor belt scale 4. When the weight reaches the packaging standard, the conveyor belt scale 4 will transport it to the inside of the hopper 5, and fall to the surface of the arc plate 6 through the bottom of the hopper 5. During this process, the motor 17 can be started to drive the rotating disk 18 to rotate, thereby driving the driving rod 19 to rotate. At the same time, the driving rod 19 moves left and right with the connection between the rotating disk 18 and the driving rod 19 as the node. That is, when the connection between the rotating disk 18 and the driving rod 19 is located at the end away from the L-shaped plate 23 (at the farthest distance), the reciprocating rod 20 will be driven to make the knocking plate 21 close to the inner side of the L-shaped plate 23. On the contrary, when the connection between the rotating disk 18 and the driving rod 19 is located near one end of the L-shaped plate 23 (when the distance between the L-shaped plate 23 is the shortest), the reciprocating rod 20 will be driven along the inside of the L-shaped plate 23, so that it pushes the knocking plate 21 to move toward the hopper 5, and makes the rubber block 22 contact with the hopper 5. This can be repeated, so that the rubber block 22 can continuously knock on the hopper 5, thereby causing the hopper 5 to vibrate, so as to speed up the discharge speed of the ferroboron material, and at the same time avoid the problem of accumulation or blockage of the ferroboron material inside the hopper 5 due to the small diameter of the discharge port.

[0032] The remaining structures are the same as those of Example 1.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
