Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a blanking device. Background Art

[0002] Existing unloading devices such as Figure 5 As shown, the hopper includes a drop hopper, which shrinks from one end of the drop inlet toward one end of the drop outlet. The drop outlet is rectangular, so that the material is more concentrated when it falls into the transfer cavity of the transfer device below the drop hopper, avoiding the material from being scattered. However, the drop outlet has a smaller width in one direction, and the long strip of material will be stuck in the smaller width when passing through the drop outlet horizontally. If the material posture is not manually adjusted, the material will always be stuck at one end of the drop outlet of the drop hopper, resulting in the material being unable to fall into the transfer cavity. At the same time, the stuck material will also block the subsequent material from falling. Summary of the Invention

[0013] The utility model with the above-mentioned features: the auxiliary push plate for blanking moves back and forth, so that materials with incorrect postures will be stuck by the auxiliary push plate for blanking. When the auxiliary push plate for blanking moves away from the center of the blanking cavity, the stuck materials can fall down. If the stuck materials fall down again and are stuck at the blanking outlet again, the auxiliary push plate for blanking will be moved toward the center of the blanking cavity again to push and adjust the material posture, so that the materials fall into the transfer cavity.

[0017] The utility model with the above-mentioned characteristics: the baffle falls to block the transfer chamber between the blanking outlet and the blanking outlet when the packaging bag has not reached the bottom of the blanking outlet, so as to prevent the material from falling directly out of the blanking outlet when falling into the transfer chamber from the blanking outlet, and unable to enter the packaging bag, resulting in an error in the packaging quantity. When the packaging belt reaches the bottom of the blanking outlet, the second drive device drives the baffle to rise, so that the transfer chamber between the blanking outlet and the blanking outlet is connected.

[0018] The beneficial effect of the utility model is that by arranging the material dropping auxiliary device which can change the material posture, the stuck material can fall again after the posture is changed, thereby avoiding manual adjustment of the material posture.
