Technical Field
[0001] The utility model relates to the technical field of fire extinguisher bottle filling equipment, in particular to a dry powder filling machine. Background Art
[0002] In order to improve the filling efficiency of dry powder fire extinguishers, when filling the fire extinguisher bottle with dry powder, the fire extinguisher bottle is generally first roughly filled to quickly approach the filling volume requirement, and then the fire extinguisher bottle is finely filled to meet the filling requirements through precise filling. In the prior art, when the fire extinguisher bottle is quickly roughly filled, due to the presence of gaps between the dry powder, the dry powder often emerges from the bottle mouth, and the fire extinguisher bottle needs to be left to settle, which affects the filling efficiency. Furthermore, during fine filling, the powder box used for fine filling contacts the fine filling components, which has a certain impact on the accuracy of the fine filling. In response to the above problems, the present utility model provides a dry powder filling machine. Utility Model Content

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0027] A dry powder filling machine, such as Figure 1-Figure 2As shown, it includes a machine body and a rough filling mechanism 1, a fine filling mechanism 2 and a vibration transfer mechanism 3 arranged on the machine body. A rough filling processing position and a fine filling processing position are provided on the machine body. The rough filling processing position is provided with the rough filling mechanism 1, and the fine filling processing position is provided with the fine filling mechanism 2. The vibration transfer mechanism 3 includes a conveying mechanism 31 and a push-pull pick-up and placement mechanism. The conveying mechanism 31 is a telescopic component or a linear motion module. The conveying part of the conveying mechanism 31 is connected to the push-pull pick-up and placement mechanism. The conveying mechanism 31 drives the push-pull pick-up and placement mechanism to move back and forth between the rough filling processing position and the fine filling processing position. The push-pull pick-up and placement mechanism includes a push-pull driving member 32, a grabbing tool 33 and a bearing member 34. The push-pull driving member 32 is provided at the conveying part of the conveying mechanism 31. The push-pull driving member 32 is a telescopic component or a linear motion module. The push-pull part of the push-pull driving member 32 is connected to the grabbing tool 33. The push-pull driving member 32 drives the grabbing tool 33 to move back and forth between the pick-up and placement position and the avoidance position.
[0028] When the push-pull pick-and-place mechanism is in the rough filling position, the gripping tool 33 moves from the avoidance position to the pick-and-place position and grabs the fire extinguisher bottle that has been roughly filled at the rough filling mechanism 1. The gripping tool 33 then moves from the pick-and-place position to the avoidance position and places the fire extinguisher bottle on the carrier 34. After the transport mechanism 31 drives the push-pull pick-and-place mechanism from the rough filling position to the fine filling position, the gripping tool 33 moves from the avoidance position to the pick-and-place position and transfers the fire extinguisher bottle on the carrier plate to the fine filling mechanism 2 for fine filling. The carrier 34 is arranged on the transport portion of the transport mechanism 31 and is equipped with a vibration drive element. During the movement of the fire extinguisher bottle from the rough filling position to the fine filling position, the vibration drive element drives the carrier 34 and the fire extinguisher bottle on the carrier 34 to continuously vibrate. The high-frequency vibration causes the ultrafine dry powder in the bottle to settle, preventing the ultrafine dry powder in the fire extinguisher bottle from emitting out of the bottle mouth.
[0029] The grabbing tool 33 is a clamping tool, which can be a finger cylinder or other form of tool in the prior art.

The dry powder filling machine of this embodiment can perform filling processing of two or more fire extinguisher bottles at a time, which effectively improves the filling efficiency.

The first clamping claw seat 332 is provided with a first clamping claw I 334 and a first clamping claw II 335. The second clamping claw seat 333 is provided with a second clamping claw I 336 and a second clamping claw II 337. Each clamping claw is arranged along the telescopic direction of the double-headed telescopic drive member 331.

The second clamping claw I 336 is located between the first clamping claw I 334 and the first clamping claw II 335, and the first clamping claw II 335 is located between the second clamping claw I 336 and the second clamping claw II 337. The cylinder gripping area is defined between the first and second gripping jaws 334 and 336, and between the first and second gripping jaws 335 and 337. Driven by the double-ended telescopic drive member 331, the first and second gripping jaws 334 and 336 cooperate to grip the cylinder located between them, while the first and second gripping jaws 335 and 337 cooperate to grip the cylinder located between them. The double-ended telescopic drive member 331 can simultaneously grip and release two cylinders. In this embodiment, a single gripping fixture 33 can achieve the purpose of two gripping fixtures 33.
[0032] In the fine filling mechanism 2, the spacing between the two fine filling platforms 21 is the same as the spacing between the two cylinder grabbing areas, so that the vibration transfer mechanism 3 can simultaneously transfer the two fire extinguisher bottles to the fine filling mechanism 2 for fine filling, and the spacing between the two rough filling platforms 11 is also the same as the spacing between the two cylinder grabbing areas, so that the vibration transfer mechanism 3 can simultaneously grab the two fire extinguisher bottles from the rough filling mechanism 1.

[0039] The powder replenishing box 25 is connected to each carrying cup 24 and replenishes powder to each carrying cup 24. Driven by the powder replenishing adjusting member 26, the powder replenishing box 25 rises and falls synchronously with the carrying cup 24 and the fine filling powder filling member 23 to avoid affecting the fine filling accuracy due to the change of partial height difference.
