[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] As Figure 1 and Figure 2 shown, the drug sub-packaging device includes a base 1, and a rotatable turntable 2 is provided on the base 1 (in this embodiment, Figure 1 the arrow indicates the rotation direction of the turntable 2). A plurality of positioning holes 22 evenly distributed in the circumferential direction are opened at the upper end of the turntable 2, and packaging bottles are placed in the positioning holes 22 in a matching manner to achieve the positioning of the packaging bottles; by controlling the turntable 2 to rotate a certain angle, one of the packaging bottles can reach the filling station to complete the filling of liquid drugs;
[0028] In this embodiment, a rotating shaft 21 is coaxially fixed at the lower end of the turntable 2. The rotating shaft 21 is rotatably connected to the base 1, and a motor is arranged at the lower end of the base 1 to drive the rotation of the rotating shaft 21, so as to drive the rotation of the turntable 2; moreover, the motor in this embodiment is a conical rotor motor, ensuring that when the packaging bottle rotates to the filling station, the motor can be braked after power-off to ensure the stability of the filling process.
[0029] A clamping component 3 is provided at each positioning hole 22. As Figure 3 shown, the clamping component 3 includes two V-shaped clamping blocks 31. The two V-shaped clamping blocks 31 can slide synchronously and reversely and can clamp the packaging bottle in the positioning hole 22 to ensure that during the filling process, the packaging bottle will not move randomly or even deviate from the positioning hole 22, causing drug spillage;
[0030] As Figure 3As shown, on the sides of two V-shaped clamping blocks 31, a first rack 32 and a second rack 33 are respectively fixed. Between the first rack 32 and the second rack 33, there is a rotating rod 34 rotatably connected to the turntable 2. A gear 35 is fixed on the rotating rod 34. The gear 35 is located between the first rack 32 and the second rack 33 and meshes with both the first rack 32 and the second rack 33 simultaneously. By driving one of the V-shaped clamping blocks 31 to move, synchronous reverse sliding of the two V-shaped clamping blocks 31 can be achieved;
[0031] Moreover, in this embodiment, both V-shaped clamping blocks 31 are slidably connected to the turntable 2. A guide rod 36 is fixed on one of the V-shaped clamping blocks 31, and a fixing plate 37 is fixed on the turntable 2. The guide rod 36 penetrates through the fixing plate 37 and is slidably connected to it. A spring 38 is sleeved on the guide rod 36. The two ends of the spring 38 are respectively fixed to the fixing plate 37 and the V-shaped clamping block 31. Under the elastic force of the spring 38, this V-shaped clamping block 31 can move closer to the packaging bottle, so that the two V-shaped clamping blocks 31 move closer synchronously to complete the clamping of the packaging bottle;
[0032] Of course, the ways to drive the V-shaped clamping block 31 to clamp the packaging bottle include but are not limited to the structures such as the spring 38, gears, and racks in this embodiment. In some embodiments, two cylinders can also be respectively arranged on both sides of each positioning hole 22 to respectively drive the two V-shaped clamping blocks 31 to slide synchronously in the reverse direction, and the clamping of the packaging bottle can also be achieved.
[0033] On the upper end of the base 1, a storage bucket 4 is provided to store the prepared liquid medicine; Figure 4 As shown, a hose 41 is connected to the storage bucket 4, and a liquid injection pipe 42 is connected to the hose 41. The liquid injection pipe 42 is a rigid pipe, and the nozzle of the liquid injection pipe 42 can be aligned with the mouth of the packaging bottle. The hose 41 is connected to a pump to discharge the liquid medicine in the storage bucket 4 from the liquid injection pipe 42 and inject it into the packaging bottle;
[0034] Moreover, in this embodiment, a cylinder 5 is fixed on the upper end of the base 1. A connecting block 6 is fixed to the end of the driving shaft of the cylinder 5, and the connecting block 6 is fixed to the liquid injection pipe 42. Under the action of the cylinder 5, the liquid injection pipe 42 can be driven to move up and down; when the nozzle of the liquid injection pipe 42 is aligned with the mouth of the packaging bottle, by controlling the liquid injection pipe 42 to descend, the nozzle of the liquid injection pipe 42 can be inserted into the packaging bottle for filling, avoiding material leakage.
[0035] In addition, in this embodiment, the liquid injection pipe 42 is made of stainless steel. In some embodiments, the material of the liquid injection pipe 42 can also be PVC.
[0036] A push rod assembly 7 is arranged on one side of each clamping assembly 3, as Figure 5As shown, the ejector rod assembly 7 includes a connecting rod 71 fixedly connected to one side of one of the V-shaped clamping blocks 31. A roller 72 is rotatably connected to the end of the connecting rod 71. A stop rod 8 is fixedly installed on the upper end of the base 1. During the rotation of the turntable 2, the roller 72 can contact and collide with the stop rod 8, driving the two V-shaped clamping blocks 31 to move away from each other, realizing the loosening of the packaging bottle. Thus, the automatic clamping and loosening of the packaging bottle are achieved, and there is no longer a need to apply external force or set up an independent power source to clamp the packaging bottle.
[0037] In this embodiment, as Figure 1 shown, after a packaging bottle is filled, as the turntable 2 rotates, the roller 72 in the ejector rod assembly 7 located at the position of this packaging bottle can collide with the stop rod 8. And when the next packaging bottle reaches directly below the liquid injection pipe 42, at the position of the packaging bottle that has been filled previously, both of the two V-shaped clamping blocks 31 leave the packaging bottle. At this time, it is convenient to remove the filled packaging bottle and place an empty packaging bottle to continue the subsequent filling operation.
[0038] Working principle:
[0039] By setting a rotatable turntable 2 on the base 1, arranging a plurality of circumferentially uniformly distributed positioning holes 22 on the turntable 2 to position the packaging bottles, and arranging a clamping assembly 3 at the positioning holes 22, and arranging two V-shaped clamping blocks 31 that can slide synchronously and in opposite directions in the clamping assembly 3 to clamp and fix the packaging bottles at the positioning holes 22, ensuring that when filling is carried out while the packaging bottle is aligned with the liquid injection pipe 42, the bottle body will not shake or even fall out of the positioning hole, causing waste of medicine. By setting a cylinder 5 on the base 1 to drive the connecting block 6 to move up and down, the liquid injection pipe 42 can be inserted into the packaging bottle for filling, further avoiding leakage of the filling material. By arranging an ejector rod assembly 7 on one side of each clamping assembly 3 to trigger by colliding with the stop rod 8 at the upper end of the base 1, driving the two V-shaped clamping blocks 31 to move away from each other, realizing the automatic clamping and loosening of the packaging bottle, and no longer requiring external force or an independent power source to clamp the packaging bottle.
