Description

Power device and dosing device

Technical Field

The invention relates to the technical field of medicine packaging, in particular to a medicine adding device, a medicine adding tank and a driving mechanism, and belongs to the medicine adding device.

Background

In the prior art, a device for adding granular medicines into a packaging can (box) generally comprises a stirring mechanism and a funnel, wherein the stirring mechanism comprises a motor arranged at the upper end of the funnel, a rotating rod vertically arranged and driven by the motor, and a stirring blade connected to the lower end of the rotating rod. When medicine needs to be added into the packaging can, the stirring blade is driven by the motor to rotate so as to fluctuate the granular medicine, and then the granular medicine flows out from the necking at the lower end of the funnel to fall into the packaging can opposite to the necking; when the packaging tank is filled with the medicine, the stirring blade stops rotating, the granular medicine stops being fluctuated by the blade, and the granular medicine close to the necking part stops falling from the necking part by virtue of extrusion force and friction force existing between the granular medicine and the blade so as to realize the effect of plugging the necking part.

The above-mentioned devices of the prior art have the following problems:

1. the blades need to maintain a certain large radial dimension for providing sufficient fluctuation, while the funnel is of a structure with a large upper part and a small lower part, in order to prevent mode interference, the stirring blades can only be arranged at a height far away from the necking, and the flow of the granular medicine flowing out of the necking cannot be well controlled by changing the rotating speed due to the fact that the stirring blades are far away from the necking, namely, the device cannot well control the flow of the granular medicine flowing out of the necking.

2. After the stirring blade stops rotating, the granular medicine is prevented from falling from the necking by using the extrusion force and the friction force, which is not reliable, some granular medicine still falls from the necking by overcoming the force, and the probability of the granular medicine falling from the necking is very high due to the vibration which is inevitably generated in real time by the device, so that the device can not strictly prevent the granular medicine from falling after the packaging tank is filled with the medicine.

3. Although in some improved structures, the buckle cover is arranged at the necking part, when batch medicine adding is carried out, the buckle cover needs to be opened or closed continuously and manually. And the appearance of the reducing part is small, so that a mechanism for automatically driving the buckle cover to open and close cannot be additionally arranged.

4. The motor for driving the stirring blade is in mechanical connection with the hopper and the stirring blade, which increases the volume of the whole structure.

For the above reasons, it is necessary to design a medicine adding device for adding medicine to a packaging can (box).

As shown in fig. 1 to 8, in one embodiment of the present invention, a medicine adding canister 10 includes: a tank 11 and a medicine control mechanism 12. The tank body 11 is roughly cylindrical, the upper end of the tank body is buckled with the tank cap 112, the tank cap 112 can be opened by screwing so as to conveniently load granular medicines into the tank body 11, the bottom of the tank body 11 is detachably provided with the bottom cover 111, the bottom cover 111 is provided with the medicine outlet 13, and the granular medicines in the tank body 11 fall into a packaging tank (box) below the medicine outlet 13 through the medicine outlet 13. The medicine control mechanism 12 is used for controlling the opening and closing of the medicine outlet 13; on the other hand, the device is used for conveying the granular medicine in the tank body 11 to the medicine outlet 13 so that the granular medicine can be led out from the medicine outlet 13. As shown in fig. 5 to 8, the medicine control mechanism 12 specifically includes: a spiral stirring body 121, a stop body 124, an elastic reset piece 125 and a trigger rod 122. The spiral stirring body 121 is composed of a mandrel and a continuous spiral blade, the spiral stirring body 121 is transversely arranged on the bottom cover 111, a main action part and a first end of the spiral stirring body 121 are positioned in the tank 11, a second end of the spiral stirring body 121 extends out of one side of the bottom of the tank 11 in the radial direction, a first connecting piece 123 is arranged on the second end, the first connecting piece 123 is used for being driven by the power device 20 so as to enable the spiral stirring body 121 to rotate, and the rotation of the spiral stirring body 121 enables the spiral blade to convey the granular medicine which is in direct contact with the spiral stirring body to the medicine outlet 13. The stopping body 124 is arranged on the bottom shell and can move, the stopping body 124 can block the medicine outlet 13 or open the medicine outlet 13 through moving, so that when medicine needs to be added to the packaging can, the stopping body 124 is driven to move to a position where the medicine outlet 13 is opened, and granular medicine in the packaging can is conveyed to the medicine outlet 13 through the spiral stirring body 121 and is continuously conveyed to add medicine to the packaging can; and after the medicine adding is finished, the stopping body 124 blocks the medicine outlet 13 by moving. The elastic restoring member 125, such as a spring, is used to push against the stopping body 124 so that the stopping body 124 is kept at a position for blocking the medicine outlet 13 when being pushed against by the spring only. The trigger rod 122 is disposed on the bottom cap 111, a first end of the trigger rod 122 faces the stopping body 124, a second end of the trigger rod 122 extends out of the can 11, the second end is a driven end, and the second end is pushed by the power device 20 in an axial direction, so that the trigger rod 122 pushes the stopping body 124 in a direction opposite to a spring force, and the stopping body 124 moves to open the medicine outlet 13. This is so: as shown in fig. 9 and fig. 7 and 8, when a medicine needs to be added into the packaging can, the power device 20 pushes the trigger rod 122, so that the stopper 124 opens the medicine outlet 13, and the elastic restoring member 125 contracts, and the power device 20 drives the first combining member 123 to drive the second combining member 27 to drive the spiral stirring body 121 to rotate, so that the medicine is conveyed to the medicine outlet 13 and falls into the packaging can; after the medicine is added, as shown in fig. 10 and in combination with fig. 5 and 6, the power device 20 is used to release the pushing of the trigger rod 122, the elastic reset piece 125 is reset to make the stopper 124 block the medicine outlet 13, and the power rotation is used to release the rotational driving of the trigger rod 122, so that the spiral stirring body 121 in the tank 11 stops delivering the granular medicine and the granular medicine does not flow out from the medicine outlet 13.

According to the medicine adding pot 10 of the present embodiment, as shown in fig. 9 and 10, the power unit 20 is provided at one side of the medicine adding pot 10 in the radial direction, and the power unit 20 includes: an application rod 28, a second coupling member 27 and a drive mechanism. The force applying rod 28 is an acting component pushing against the trigger rod 122, and the second engaging member 27 is an acting component for engaging with the first engaging member 123 of the dosing tank 10 and driving the first engaging member 123 to rotate the helical stirring body 121. The power of the force application rod 28 and the second joint 27 is from the driving mechanism. Specifically, the drive mechanism is configured to: the force application rod 28 is pushed against the trigger rod 122 of the medicine adding pot 10 or separated from the trigger rod 122, and is used for combining the second combining member 27 with the first combining member 123 of the medicine adding pot 10 and driving the first combining member 123 to rotate or separating the second combining member 27 from the first combining member 123. Thus, as shown in fig. 9, when a medicine needs to be added to the packaging can, the driving mechanism drives the force application rod 28 to move towards the trigger rod 122 to push against the trigger rod 122, so that the stopper 124 opens the medicine adding opening, and the driving mechanism also drives the second combining member 27 to move towards the first combining member 123 and combine with the first combining member 123, and drives the second combining member 27 to rotate by using the driving mechanism, so that the first combining member 123 drives the spiral stirring body 121 to rotate, so as to deliver the granular medicine to the medicine outlet 13 and force the granular medicine to fall into the packaging can; as shown in fig. 10, after the medicine is added, the driving mechanism drives the force applying rod 28 to move away from the trigger rod 122, the stopper 124 is reset by the elastic reset piece 125 to close the medicine outlet 13, the driving mechanism not only stops driving the second engaging member 27 to rotate, but also drives the second engaging member 27 to move away from the first engaging member 123, so that the spiral stirring body 121 stops rotating due to the loss of power.

The above-described embodiments of the present invention have the advantages that:

1. the cylindrical tank body 11 enables the spiral stirring body 121 to be transversely arranged and the position of the spiral stirring body is closer to the medicine outlet 13, so that the flow of the granular medicine flowing out from the medicine outlet 13 can be more effectively controlled.

2. Horizontal spiral stirring body 121 makes the granule medicine have unanimous direction of transport through rotating, and make the granule medicine of the back position of direction of transport have certain pushing effect to the granule medicine of preceding position, and then make the granule medicine rely on pushing force from the outflow of medicine outlet 13, make the outflow process more continuous orderly, and, the outflow of granule medicine has more strict relation with spiral stirring body 121's rotational speed, and then adjusts the flow from the granule medicine that medicine outlet 13 flows through the rotational speed of adjusting spiral stirring body 121.

3. Set up in the backstop body 124 of jar body 11 bottom can make out medicine mouth 13 and open and close through the removal, after the completion adds the medicine, close out medicine mouth 13 through backstop body 124 and can avoid granule medicine still can follow out medicine mouth 13 and flow after the completion adds the medicine completely.

4. The trigger end (second end) of the trigger rod 122 and the driven end (second end) of the helical agitator body 121 both extend radially out of the canister, which facilitates separable driving with the power unit 20, namely: when dosing is completed, the power device 20 restricts access to the dosing tank 10 by removing the force applying rod 28 and the second coupling member 27.

The first engaging member 123 and the second engaging member 27 may preferably be face gears capable of engaging with each other so that the two engaging members can rotate synchronously after being abutted.

In a preferred embodiment of the present invention, the trigger rod 122 of the dosing tank 10 is arranged in parallel with the spiral agitator 121, and the second end of the trigger rod 122 is located on the same side as the second end of the spiral agitator 121, so that the force applying rod 28 and the second engaging member 27 in the power device 20 can be close to and act on the trigger rod 122 and the first engaging member 123 by moving in the same direction, thereby enabling the power device 20 to be arranged more compactly and the power output to be more convenient. In addition, the trigger rod 122 and the spiral stirring body 121 are arranged in parallel, so that the whole medicine control mechanism 12 is arranged more compactly and orderly.

The first driving assembly 21 is used for driving the synchronizing block 24 to move along the guide rail 262 so that the force applying rod 28 and the second coupler 27 synchronously contact the triggering rod 122 and the first coupler 123 or synchronously separate from the triggering rod 122 and the first coupler 123. The first driving assembly 21 specifically includes: a first servo motor 211, a rack 213, and a gear 212. The first servo motor 211 is vertically disposed on the mounting plate 25 with its output shaft protruding out of the bottom of the mounting plate 25, the rack gear 213 is fixed on the synchronizing block 24 and arranged along the extending direction of the guide rail 262, and the gear 212 is mounted on the output shaft and configured to mesh with the rack gear 213.
