Description

Technical Field

[0001] The utility model relates to the technical field of powder production, in particular to a powder feeding vibrating compaction device and a feeding mechanism. Background Art

[0002] In industrial production, powder production is carried out in many industries, such as powder metallurgy, toner, coke graphite, magnetic materials, biopharmaceuticals, high-new energy materials, plastics, and milk powder food ingredients. After powder production, ton bags are usually used for packaging and then transported to the next production process. Ton bags are mainly placed below the powder discharge port, and the products after powder production enter the ton bags through the discharge port. Although ton bags have good strength and waterproof properties and are convenient for transportation and handling, most current ton bags are directly placed below the powder discharge port, and there is no vibrating compaction device to compact the powder after it enters the ton bag, which leads to the following problems in the powder feeding process:

[0003] 1. Due to the absence of a vibrating compaction device, the materials filled in the ton bag are prone to looseness during the powder discharging process, resulting in space gaps and bulges inside the ton bag;

[0004] 2. After the ton bag is filled with materials, its weight is relatively large, and it is difficult to perform the exhaust vibrating compaction operation after filling;

[0005] 3. During the filling process of the ton bag, the original air in the bag needs to be discharged when feeding at the material port, which causes a large amount of dust to be directly discharged from the bag mouth along with the air, not only polluting the production environment but also causing waste of powder.

[0006] In view of the above defects, the prior art has added a powder vibrating compaction device to the ton bag during the powder feeding process. For example, the patent with the publication number CN212423724U discloses a vibrating compaction and shaping device for a ton bag for packaging battery-grade lithium carbonate, which includes a base, vibration isolation springs, vibration motors, and a bearing platform. The device also includes a roller guardrail, which is fixedly arranged on the bearing platform. Although this patent can perform powder vibrating compaction, it still has the following defects: the motor is installed on the base, and the space is easily limited, and there is a risk of rubbing during transportation on the conveyor belt; the vibration isolation springs are fixed to the device, and their elasticity cannot be adjusted, which is not convenient for flexibly adjusting the vibration frequency; the way to exhaust air in this patent is achieved by the reciprocating rotation of the rollers to squeeze the ton bag, which requires the assistance of workers to roll, and the practicability is poor.

[0007] Based on the above analysis, it can be seen that the existing powder vibrating compaction devices still have certain defects and there is still room for improvement. Therefore, the field continues to improve the powder vibrating compaction device to overcome the defects existing in the prior art. Summary of the Utility Model

[0018] Furthermore, a dust removal device is also included, and a dust suction pipe for extending into the ton bag for dust suction is provided on the dust removal device.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. The vibration springs and vibration motors of the present utility model cooperate to drive the entire vibration device to vibrate, so as to compact the powder entering the ton bag, prevent the powder from loosening and the appearance of gaps between the powder and the ton bag.

[0021] 2. The present utility model arranges the vibration motor on the outer surface of the fence to ensure that there is sufficient space around the vibration motor, prevent the bearing platform from pressing the vibration motor when the adjusting bolt is adjusted too loose, and ensure the safety of the equipment.

[0022] 3. The utility model can adjust the vibration degree by adjusting the screw rod, without the need to adjust the vibration frequency of the vibration motor. The adjustment of the vibration frequency is achieved through a simple mechanical structure, enabling the vibration motor to operate at low power while achieving the high-power vibration effect of the powder feeding and compaction device.

[0032] AsFigures 1 to 3 As shown in the figure, a powder feeding compaction device includes a base 1, a loading platform 2 above the base 1 for placing a ton bag 13, a vibration spring 3 connecting the base 1 and the loading platform 2, and a tensioning screw 4 also provided between the base 1 and the loading platform 2; it also includes a fence 5 arranged on the loading platform 2, and a vibration motor 6 is further provided on the outer surface of the fence 5.

[0033] The device of this embodiment is mainly used for compaction during the process of loading powder materials into the ton bag 13 after production, avoiding situations such as looseness when the materials enter the ton bag 13, and making better use of the space inside the ton bag 13. When discharging the powder, place the ton bag 13 inside the fence 5 on the loading platform 2, then connect the top of the ton bag 13 to the outlet of the discharging device, and start the vibration motor 6 during the loading process of the ton bag 13. The vibration motor 6 is connected to an external power source. After starting the vibration motor 6, the fence 5 can be made to shake and drive the entire vibration device to shake, thereby compacting the powder entering the ton bag 13, preventing the powder from loosening and the formation of gaps between the powder and the ton bag 13.

[0034] The tensioning screw 4 passes through the loading platform 2 and is threadedly connected to the base 1 at the lower end. The vibration degree of the vibration spring 3 can be adjusted by adjusting the tightness of the tensioning screw 4. When the device of this embodiment is working, the vibration degree can be adjusted by adjusting the screw, without the need to adjust the vibration frequency of the vibration motor 6. That is, the adjustment of the vibration frequency is achieved through a simple mechanical structure, realizing the low-power operation of the vibration motor 6 while achieving the high-power vibration effect of the powder feeding compaction device. It not only has high work efficiency but also is energy-saving and highly practical.

[0035] The vibration spring 3 is a helical spring, and its elastic coefficient can be selected according to actual needs. The upper end of the vibration spring 3 is fixedly connected to the lower surface of the support platform. To ensure the stability of vibration, in this embodiment, the number of vibration springs 3 is more than two, and they are evenly distributed on the edge of the base 1. A spring seat 7 is provided at the lower end of each vibration spring 3, and the spring seat 7 is fixedly connected to the base 1. In a preferred solution of this embodiment, the number of vibration springs 3 is four, and the four are evenly distributed on the edge of the base 1.

[0037] In this embodiment, the shapes of the base 1 and the loading platform 2 are polygons. For the convenience of processing and production, the base 1 and the loading platform 2 are designed as squares in this embodiment, and the fence 5 is arranged along the edge of the loading platform 2. In the above structure, since the loading platform 2 is square and the fence 5 is arranged along the edge of the loading platform 2, the fence 5 includes a total of four sides.

[0038] The number of vibrating motors of the vibrating machine is more than one, and a fixed guard plate 8 is also provided between the vibrating motor 6 and the surface of the fence 5. In a preferred solution of this embodiment, the number of vibrating motors of the vibrating machine is two, and the two vibrating motors 6 are respectively arranged on two opposite sides of the fence 5 (that is, on the fence 5, only one of the two adjacent sides is provided with the vibrating motor 6). This method can achieve stable vibration while saving parts. The fixed guard plate 8 is a plate-like structure, one side of which is fixed to the outer surface of the fence 5 by welding or bolt connection, etc., and the other side is used to install the vibrating motor 6.

[0039] The shape of the fence 5 is a common shape in the prior art, such as a mesh-shaped, horizontally strip-shaped, and vertically strip-shaped fence 5, and the specific shape can be selected according to actual needs. For the convenience of processing and material saving, in this embodiment, the fence 5 is preferably a vertically strip-shaped fence 5. Specifically, in this embodiment, the fence 5 includes a plurality of columns 501 and a cross beam 502 at the top of the columns 501 for connecting the columns 501.
