Embodiment 1

[0052] The bag packaging machine in this embodiment is a valve bag packaging machine, such as Figure 1 to Figure 4As shown, the bag packaging machine comprises a frame 15, a feed shell is provided above the frame 15, a filter cartridge dust collector 16 is provided below the frame 15, and a discharge nozzle 19 is provided at the bottom of the feed shell, and a discharge nozzle 19 is provided at the bottom of the feed shell. The powder in the shell enters the valve pocket through the discharge nozzle 19. Wherein, the valve bag constitutes a material bag. In other embodiments, the pocket is an open-mouth bag.

[0053] In this embodiment, the feeding shell includes a hopper 11, a feeding barrel 12, and a feeding barrel 13 arranged sequentially from top to bottom. the end. When working, the powder enters the feeding barrel 12 through the hopper 11, and enters the feeding barrel 13 through the feeding barrel 12. Under the action of the feeder, the powder is transported to the d...

Embodiment 2

[0073] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the end of the twin-screw near the outlet 44 of the dust conveying case is suspended. In this embodiment, a support plate is provided at the end of the twin-screw close to the outlet of the dust-conveying case in the dust-conveying case. The support plate extends along the arrangement direction of the twin-screws. The ends of the twin-screws are rotated and assembled on the support plate. , the width of the support plate is as small as possible.

Embodiment 3

[0075] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the discharge nozzle gas collection case 20 is fixed on the filling seat 21, and the air inlet pipe 17 communicates with the discharge nozzle gas collection case 20, so as to facilitate the filling with powder. The air enters in the dust removal case 35. In this embodiment, the filling seat is not provided with a discharge nozzle gas collecting shell, and the end of the air inlet pipe close to the discharge nozzle is a flared structure, and this end is fixed on the filling seat.

Abstract

The invention relates to a bag type packaging machine. The bag type packaging machine comprises a feeding shell, a discharging nozzle, a dust removal shell, a filter cartridge, a dust removal shell air inlet, a fan exhaust assembly, a dust removal shell dust outlet, a screw dust conveying assembly, an air inlet pipe and a material return pipe, wherein a conveyor is arranged in the feeding shell; the discharging nozzle is arranged at the bottom of the feeding shell; a flowing cavity is formed in the dust removal shell; the filter cartridge is arranged in the flowing cavity; the dust removal shell air inlet is formed in the side part of the dust removal shell; the fan exhaust assembly comprises a fan and an exhaust pipe, and the exhaust pipe is connected with the fan and the dust removal shell; the dust removal shell dust outlet is formed in the bottom of the dust removal shell; the screw dust conveying assembly comprises a dust conveying shell and double screws, a dust conveying shell inlet and a dust conveying shell outlet are formed in the dust conveying shell, the dust conveying shell inlet communicates with the dust removal shell dust outlet, and the double screws are arranged in the dust conveying shell in parallel and are the same in rotation direction; one end of the air inlet pipe is connected to the dust removal shell air inlet, and the other end of the air inlet pipe is located at the discharging nozzle, so that air with dust discharged by a material bag enters the dust removal shell; and one end of the material return pipe is connected to the dust conveying shell outlet, and the other end of the material return pipe is connected to the feeding shell, so that the filtered dust is conveyed into the feeding shell through the double screws.

Description

technical field [0001] The invention relates to a bag packaging machine. Background technique [0002] At present, the powder is generally loaded into the material bag by a bag-type packaging machine. For example, the Chinese patent document CN211766403U discloses a packaging machine including a hopper, a screw feeder is provided in the hopper, and an outlet is provided at the bottom of the hopper. Material nozzle, the powder in the hopper enters the material bag through the discharge nozzle. In order to improve the flow performance of the dry powder, compressed air needs to be mixed into the powder in the discharge nozzle, and the air in the bag needs to be discharged after the powder bag is filled. Since the discharged air carries dust, in order to avoid dust pollution to the environment, pipes are generally used to connect remote dust removal units to filter the air discharged from the bag. [0003] The Chinese patent document with the authorized announcement number CN2...
