Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging machines, in particular to a device for controlling visible foreign matter in powder packaging. Background Art

[0002] The original powder filling machine is composed of a powder feeding tee, a powder feeding screw, a filling screw, a visual powder chamber, a powder hopper, a powder nozzle, an agitator, an αβ valve, a servo system, and a detection switch. When the product bag or syringe bottle arrives at the filling station, the detection switch detects the product bag or syringe bottle and sends a signal to the PLC. The PLC then sends a signal to the servo control system. The servo motor drives the filling screw to fill the product bag or syringe bottle. During the filling process, the agitator in the visual powder chamber is in continuous and uninterrupted operation to ensure the fluffiness of the raw materials in the visual powder chamber. When the servo motor reaches the set value, it stops running and the filling is completed. When the number of fillings reaches the set value, the powder feeding motor drives the powder feeding screw to run and replenish the visual powder chamber. During the entire cycle, irresistible factors may cause friction between components and produce visible foreign matter, which seriously affects product quality and the patient's medication safety cannot be reliably guaranteed. Among them, the filling screw is driven by gears. The collision of gears may produce debris, which then falls into the powder chamber and contaminates the powder, causing adverse effects on product production.

[0003] Some powder filling machines use the powder feeding screw in the powder feeding mechanism, driven by the motor, to feed the raw powder in the raw material barrel through the αβ valve into the visible powder chamber. The raw powder fed by the powder feeding mechanism is continuously and evenly stirred in the visible powder chamber by the agitator. The filling screw rotates under the drive of the servo motor according to the set pulse parameters to fill the raw powder into the product bag or syringe bottle. This filling mechanism has the characteristics of simple structure and high efficiency, but the visible foreign matter control during operation is poor. The foreign matter generated by the friction between components cannot be effectively and timely prevented, which brings significant quality risks to the product. Therefore, the powder filling machine urgently needs to invent a device that can effectively prevent and control visible foreign matter in the filling process to solve the problem of visible foreign matter encountered in the filling process.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "up", "down", "inside", "outside", "bottom", etc. used in this specification to indicate directions or positional relationships are based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] like Figures 1-6The device shown is a powder packaging device for controlling visible foreign matter, including an installation box 1, which includes an installation cabin 102 and a visible powder cabin 101; a packaging screw drive shaft 201 is rotatably connected in the installation cabin 102, and an agitator drive shaft 3 is sleeved on the outside of the packaging screw 6. A first gear 701 for driving the packaging screw drive shaft 201 to rotate is installed on the top of the packaging screw drive shaft 201, and a second gear 702 for driving the agitator drive shaft 3 to transmit is installed on the top of the agitator drive shaft 3. An anti-foreign matter cup 4 is fixedly connected to the bottom of the agitator drive shaft 3, and a foreign matter groove is formed between the inner wall of the anti-foreign matter cup 4 and the outer wall of the agitator drive shaft 3. The foreign matter groove is used to receive foreign matter generated when the first gear 701 or the second gear 702 rotates.

[0025] In this embodiment, the foreign matter groove formed between the anti-foreign matter cup 4 and the agitator drive shaft 3 is used to receive foreign matter generated during the collision of the gears, thereby preventing foreign matter from falling into the powder chamber 101, thereby preventing foreign matter from contaminating the powder and protecting the powder from contamination.

[0026] A bearing 202 is provided on the sub-assembly screw drive shaft 201, and the sub-assembly screw drive shaft 201 is connected to the installation cabin 102 through the bearing 202; the top and bottom of the bearing 202 are respectively provided with seals 203 that are sleeved on the sub-assembly bearing 202 drive shaft; the seal 203 is existing technology.

[0027] In this embodiment, the seal 203 is provided to seal the upper and lower sides of the bearing 202 to prevent impurities generated by friction between the bearing 202 and the sub-packaging screw drive shaft 201 from falling downward.

[0028] An agitator 5 is connected to the outside of the anti-foreign object cup 4; the agitator 5 includes a first component 501 and a second component 502, and the first component 501 and the second component 502 are arranged on both sides of the anti-foreign object cup 4, and the top of the first component 501 and the second component 502 are fixedly connected to the outer wall of the anti-foreign object cup 4.

[0029] The stirrer 5 in this embodiment has a simple structure and is easy to manufacture and use.

[0030] A mounting hole is provided at the bottom of the mounting chamber 102 for the sub-packaging screw drive shaft 201 and the agitator drive shaft 3 to pass through. The diameter of the mounting hole is smaller than the diameter of the top opening of the anti-foreign object cup 4; the diameter of the bottom opening of the anti-foreign object cup 4 is adapted to the diameter of the sub-packaging screw drive shaft 201.

[0031] In this embodiment, the diameter of the top opening of the anti-foreign object cup 4 is larger than the diameter of the mounting hole, so that the top opening of the anti-foreign object cup 4 completely covers the mounting hole, thereby avoiding the possibility of impurities generated between gear collisions falling from the outside of the anti-foreign object cup 4, and further avoiding the possibility of impurities falling into the powder.

[0032] The installation box 1 includes a lower powder hopper 103 , an observation window 1012 is provided on one side of the powder cabin 101 , a powder filling port is provided on the other side, a lower powder hopper 103 is provided at the bottom of the powder cabin 101 , and a lower powder nozzle 1031 is provided at the bottom of the lower powder hopper 103 .

[0034] Working principle: The first gear 701 is driven by a first driving mechanism, and the second gear 702 is driven by a second driving mechanism. The first driving mechanism and the second driving mechanism are prior art and are not shown in the figure.

[0035] When the first gear 701 transmits power to the first rear driving mechanism, and when the second gear 702 transmits power to the second transmission mechanism, impurities may be generated due to the interaction between the gears. The generated impurities move downward and fall into the installation chamber 102 or fall into the foreign matter protection cup 4 through the installation hole for storage, and avoid falling into the powder chamber 101.

[0036] The first gear 701 drives the packaging screw transmission shaft 201 to rotate, the packaging screw transmission shaft 201 drives the packaging screw 6 to rotate, and the powder is quantitatively packaged through the packaging screw 6; the second gear 702 drives the agitator transmission shaft 3 to rotate, the agitator transmission shaft 3 drives the anti-foreign matter cup 4 to rotate, and the anti-foreign matter cup 4 drives the agitator 5 to rotate.
