Specifically, the base platform 20 is located directly above the base 10, and the second step 21 is located directly above the first step 11. The first step 11 is fixed above the base 10, and the second step 21 is fixed on the lower end surface of the base platform 20. At the same time, the number of the first step 11 and the second step 21 is the same as that of the springs 30, both being four, to improve the stability during the vibration process. The upper end of the spring 30 is sleeved and fixed on the second step 21, and the lower end is sleeved and fixed on the first step 11. Therefore, the four springs 30 can stably support the base platform 20.

[0038] For details, please refer to Figure 1 In this powder packaging auxiliary device, the auxiliary mold 40 is used to place the bag. The bag is placed in the cavity 421 of the auxiliary mold 40, then the powder is poured into the bag, and then the vibration device 50 is used to compact it. This powder packaging auxiliary device further includes a bag-opening device 60 for opening the bag. Specifically, before the powder is poured into the bag, after the bag is placed in the cavity 421 of the auxiliary mold 40, the bag-opening device 60 is used to open the bag so that the bottom and side walls of the bag are as close as possible to the bottom and side walls of the cavity 421. Specifically, the bag-opening device 60 includes an opening plate 61 having the same internal shape as the cavity 421 and a grip rod 62 provided on the opening plate 61. The bottom of the grip rod 62 is directly fixed at the center of the opening plate 61, and it can be fixed by welding or screwing.

[0039] The auxiliary mold 40 has various specifications. According to the packaging specifications of different bags, the auxiliary mold 40 of the corresponding specifications can be replaced. The internal cavity 421 of the auxiliary mold 40 has a packaging bag and a support device that match its size, that is, the outer edge shape of the support plate 61 of the support device is consistent with the horizontal cross-sectional shape inside the cavity 421, and the size of the outer edge of the support plate 61 is slightly smaller than the shape inside the cavity 421. Therefore, the auxiliary mold 40 of the utility model is detachably connected to the base 20; specifically, the upper end surface of the base 20 is provided with a first mounting position 22 for placing the auxiliary mold 40, and the powder packaging auxiliary device also includes a block for limiting the auxiliary mold 40 within the first mounting position 22; the detachable connection of the auxiliary mold 40 is matched with the block, and the auxiliary mold 40 can also be quickly installed and disassembled.

[0040] Please refer to Figure 4 , 6 The auxiliary mold 40 includes a first bottom plate 41 and a mold body 42 arranged above the first bottom plate 41. The first mounting position 22 includes two first limiting steps 221 arranged side by side and a second limiting step 222 arranged at one end of the two first limiting steps 221. A limiting groove 2211 is arranged on the inner side of the two first limiting steps 221. The first bottom plate 41 adopts a three-dimensional structure, and the cavity 421 is arranged on the mold body 42. The internal shape of the cavity 421 is selected according to needs. The shape of the horizontal cross-section of the cavity 421 is square or circular, etc. The two first limiting steps 221 and the second limiting step 222 are arranged vertically. The limiting groove 2211 is arranged so that the first bottom plate 41 can be attached to the upper end surface of the base 20, that is, the first bottom plate 41 is prevented from moving along the Z-axis direction and the first bottom plate 41 is prevented from moving along the X-axis direction. The second limiting step 222 is matched with the baffle 70 to prevent the first bottom plate 41 from moving along the Y-axis direction.

[0041] Of course, the vibration device 50 in the utility model can be directly fixedly arranged under the base 20; at the same time, in order to adapt to vibration devices 50 of different specifications or to facilitate the disassembly, maintenance / replacement of the vibration device 50, the vibration device 50 can be detachably arranged under the base 20. For example, when the amount of powder to be vibrated is relatively large, the vibration device 50 with a larger vibration force can be directly replaced. When the amount of powder to be vibrated is small, the vibration device 50 with a smaller vibration force can be used to reduce energy consumption. Specifically, the lower end surface of the base 20 is provided with a second mounting position 23 for placing the vibration device 50, and the vibration device 50 is restricted in the second mounting position 23 by a block.

[0042] The stopper is detachably connected to the base 20, and includes a resisting portion 71 for restricting the auxiliary mold 40 within the first installation position 22, and a plugging portion 72 disposed below the resisting portion 71. A first through hole 24 for cooperating with the plugging portion 72 is provided on the base 20. After the plugging portion 72 is inserted into the first through hole 24, the vibrating device 50 can also be restricted within the second installation position 23.

[0043] For details, please refer to Figure 2 , 3 , 5. The vibrating device 50 includes a second bottom plate 51 and an oscillator 52 disposed below the second bottom plate 51. After the vibrating device 50 is installed in place, the second bottom plate 51 is located within the second installation position 23. The structure of the second installation position 23 is the same as that of the first installation position 22, and the size of the second bottom plate 51 can be the same as that of the first bottom plate 41. When the auxiliary mold 40 and the vibrating device 50 are installed, they can be directly slid into the first installation position 22 and the second installation position 23 respectively. After being installed in place, the plugging portion 72 is placed into the first through hole 24, so that the auxiliary device can be restricted within the first installation position 22, and at the same time, the vibrating device 50 can be restricted within the second installation position 23.

[0044] For details, please refer to Figures 7 to 8 , in order to achieve stable vibration of the base 20, another embodiment of the present utility model is: a limiting rod 80 is further provided on the second step 21, a second through hole 25 for the limiting rod 80 to pass through is provided on the base 20, a gap is provided between the second through hole 25 and the limiting rod 80, and a third limiting step 81 is further provided on the limiting rod 80 and below the first step 11, and a gap is provided between the third limiting step 81 and the first limiting step 221.

[0045] The working principle of the packaging auxiliary device of the present utility model is as follows:

[0046] During use, first select the auxiliary mold 40 corresponding to the packaging specification (such as 25 kg grade). After connecting the auxiliary mold 40 and the vibrating device 50 to the base 20, the auxiliary mold 40 and the vibrating device 50 can be simultaneously restricted or fixed by using the baffle 70. The packaging bag of the corresponding specification is placed into the auxiliary mold 40. During the process, a spreading device can be used to press the packaging bag into the auxiliary mold 40 and fit well with the auxiliary mold 40; then the powder to be packaged is added into the packaging bag. After the feeding is completed, the bag mouth is tied tightly. The power of the vibrating device 50 is turned on. After the powder is vibrated and compacted in the auxiliary mold 40, the auxiliary mold 40 filled with the powder is removed and transferred to a vacuum heat sealer for vacuum heat sealing treatment. Finally, the packaged powder is taken out of the auxiliary mold 40.

[0047] In summary, the packaging auxiliary device of the present utility model is provided with an auxiliary mold in cooperation with a vibration device, and a spring is also provided for vibrating and packaging powder materials, avoiding waste of powder. After packaging, the powder presents a regular shape (such as a cube or a cylinder), which is convenient for stacking and transportation.
