[0032] The buffer assembly 34 includes a rubber sleeve 341, the upper and lower sides of the rubber sleeve 341 are respectively fixedly connected to the opposite surfaces of the support plate 32 and the rubber pad 33, the inner cavity of the rubber sleeve 341 is movably sleeved with a spring 342, the upper and lower sides of the spring 342 are respectively fixedly connected to the opposite surfaces of the support plate 32 and the rubber pad 33; through the action of the rubber sleeve 341 and the spring 342, the barrel can play a supporting and buffering role when introducing materials into the bag, thereby preventing the bag from being damaged due to the descending speed of the material, and at the same time, due to the elasticity of the spring 342, the material can be evenly dispersed in the bag, thereby facilitating loading.

[0033] like Figure 6 , Figure 7 As shown, the bag supporting assembly 5 includes a fixing block 51, the upper surface of which is fixedly connected to the lower surface of the bag forming assembly 4, the inner wall of the fixing block 51 is rotatably connected to a connecting block 52, and the lower surface of the connecting block 52 is fixedly connected to a supporting rod 54; the upper surfaces of the left and right parts of the connecting block 52 are fixedly connected to springs 53, and the upper surfaces of the two springs 53 are respectively fixedly connected to the inner wall of the fixing block 51; through the action of the springs 53, the connecting block 52 can have a certain buffer space under the action of the fixing block 51, and at the same time, through the action of the rubber pad 55, the supporting rod 54 will not cause damage to the bag when supporting the bag, thereby preventing damage to the bag.

The effect of the rubber pad 255 is to ensure that the connecting block 52 has a certain buffer space under the action of the fixed block 51, and the support rod 54 will not cause damage to the bag when supporting the bag through the action of the rubber pad 255, so that the material barrel inside the bag forming assembly 4 can drop into the sealed bag. At this time, through the action of the rubber sleeve 341 and the spring 1 342, the barrel can play a supporting and buffering role when introducing the material into the bag, thereby preventing the bag from being damaged due to the falling speed of the material. After the material is loaded, it is sealed and cut off.
