[0001] The invention belongs to the field of vitamin tablet filling, and in particular relates to a fully automatic filling device compatible with vitamin tablets of multiple sizes. Background Art

[0002] Vitamins are essential substances for maintaining human health. Although the required amount is small, they cannot be synthesized in the body and must be supplemented from food. Vitamins are essential for maintaining normal growth and development of the human body and regulating various physiological functions. Vitamin tablets are a convenient form of vitamin supplementation. There are vitamin tablets in the form of medicines, and there are also chewable vitamin tablets as health foods.

[0003] Filling is an important part of the vitamin tablet production process, which is the process of putting the produced vitamin tablets into the packaging container. During filling, a guide device is usually set at the device outlet, and a constriction is set at the end of the guide device to guide the vitamin tablets into the container. There are many specifications of vitamin tablets (for example, specifications are 1000 mg / tablet, etc.), and the sizes of vitamin tablets of different specifications are different. In order to adapt to the guided filling of vitamin tablets of different sizes and prevent the constriction from getting stuck when filling larger vitamin tablets, the constriction size at the end of the guide device needs to be adjusted accordingly during filling. For this reason, a fully automatic filling device compatible with multi-size vitamin tablets is proposed. Summary of the invention

[0027] 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 described embodiments 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.

[0028] The fully automatic filling device for vitamin tablets of various sizes is compatible, comprising a bottom plate 1, a guide tube 2 is arranged above the bottom plate 1, and the processed vitamin tablets are poured from the upper end of the guide tube 2 and introduced into the bottle body along the guide tube 2;

[0029] like Figure 2 As shown, a support column 21 is fixed to the lower end of the material guide box 2 , and the support column 21 is fixed to the upper end of the bottom plate 1 to support and fix the material guide tube 2 .

[0030] A turntable 3 is arranged above the bottom plate 1. In this embodiment, a motor is fixed to the upper end of the bottom plate 1 to directly drive the turntable 3 to rotate intermittently; Figure 3 As shown, a plurality of circumferentially evenly distributed positioning grooves 31 are provided at the upper end of the turntable 3, and a bottle body 4 is mounted in the positioning groove 31. Under the intermittent drive of the motor, the bottle body 4 can move to the bottom of the outlet of the guide tube 2 to receive and pack the fallen vitamin tablets.

[0031] A notch 22 is provided at the outlet of the guide tube 2, and a necking adjustment component 5 is installed at the notch 22 to adjust the necking size at the outlet of the guide tube 2, so as to adapt to the guided filling of vitamin tablets of different sizes and prevent the necking from getting stuck when filling vitamin tablets of larger sizes; and after the filling is completed, the outlet of the guide tube 2 can be closed;

[0032] like Figure 4 As shown, the necking adjustment component 5 includes two flaps 51 that can be synchronously flipped in opposite directions at the notch 22. The two flaps 51 are flipped until the ends are in contact, so that the outlet of the material guide tube 2 can be closed, and the size of the necking at the outlet of the material guide tube 2 can be adjusted by adjusting the flipping angle of the two flaps 51;

[0033] In this embodiment, if Figure 4 and Figure 5 As shown, a rotating shaft 511 is provided on the flap 51, and the rotating shaft 511 is rotatably connected to the material guide tube 2. A gear 52 is fixed to the rotating shaft 511 of the two flaps 51 respectively. A sliding frame 53 is slidably connected to the material guide tube 2, and two racks 54 are fixed to the sliding frame 53. The two racks 54 are respectively meshed with the two gears 52. By controlling the sliding frame 53 to slide, the two flaps 51 can be synchronously flipped in opposite directions.

[0034] Moreover, in the present embodiment, two first fixed plates 55 are fixed on the material guide tube 2, and a screw rod 56 is rotatably connected between the two first fixed plates 55. The screw rod 56 passes through the sliding frame 53 and is threadedly connected thereto. By arranging a motor on one of the first fixed plates 55 to drive the screw rod 56 to rotate, the sliding frame 53 can be driven to slide, so as to achieve the purpose of flipping the two flaps 51. In order to ensure the stability after the necking size is adjusted, the screw rod 56 needs to have self-locking properties, that is, the thread lead angle of the screw rod 56 is smaller than the equivalent friction angle.

[0035] Of course, the method of driving the two flaps 51 to flip and adjust includes but is not limited to the gears, racks, screw rods and other structures in this embodiment. In some embodiments, two motors can be set on the guide tube 2 to drive the two flaps 51 to flip and adjust around the rotating shaft 511 thereon, and control the two flaps 51 to flip in opposite directions synchronously, so as to achieve the purpose of adjusting the size of the shrinkage.

[0036] The guide tube 2 is provided with a locking assembly 6, which can engage with the gear 52 to limit the turning of the flap 51, so that when the bottle body 4 does not move to the position directly below the outlet of the guide tube 2, the opening of the guide tube 2 is blocked and will not suddenly open to cause leakage;

[0037] like Figure 6 As shown, the locking assembly 6 includes a mounting frame 62 slidably connected to the guide tube 2, and a clamping block 65 is fixed at the end of the mounting frame 62. The clamping block 65 can be engaged with two adjacent teeth of the gear 52, so as to achieve the purpose of limiting the flipping of the flap 51;

[0038] In this embodiment, a second fixed plate 61 is fixed on the material guide tube 2, and two guide rods 63 are fixed on the mounting frame 62. The guide rods 63 pass through the second fixed plate 61 and are slidably connected thereto. A first spring 64 is sleeved on the guide rod 63. The two ends of the first spring 64 are respectively fixed to the second fixed plate 61 and the mounting frame 62. Under the elastic force of the first spring 64, the block 65 can engage with two adjacent teeth of the gear 52 to limit the flipping of the flap 51.

[0039] A trigger assembly 7 is provided at the upper end of the bottom plate 1 to associate the rotation position of the turntable 3 with the locking action of the locking assembly 6, so as to control the turning timing of the flap 51; and, in this embodiment, when the bottle body 4 does not move to the position directly below the outlet of the material guide tube 2, the adjustment of the flap 51 can be limited, so that the flap 51 always keeps the outlet of the material guide tube 2 closed to avoid material leakage;

[0040] like Figure 7As shown, the trigger assembly 7 includes a support frame 71 fixed to the upper end of the bottom plate 1, a sliding rod 72 is slidably connected to the support frame 71, a connecting seat 73 is fixed to one end of the sliding rod 72, a roller 74 is rotatably connected to the connecting seat 73, a second spring 75 is sleeved on the sliding rod 72, and the two ends of the second spring 75 are respectively fixed to the connecting seat 73 and the support frame 71, under the elastic force of the second spring 75, the roller 74 can be closely attached to the side wall of the turntable 3, and because the roller 74 has a degree of rotational freedom, it will not restrict or interfere with the rotation of the turntable 3;

[0041] like Figure 3 As shown, the turntable 3 is provided with a plurality of arc-shaped bosses 32 evenly distributed in the circumferential direction, and the arc-shaped bosses 32 correspond to the positioning grooves 31 one by one; when the turntable 3 rotates, the arc-shaped bosses 32 can contact with the roller 74 and drive the sliding rod 72 to slide in the direction away from the turntable 3; and when the bottle body 4 moves to the right below the outlet of the guide tube 2, the arc top of the arc-shaped boss 32 contacts with the roller 74, so that the sliding rod 72 moves to the farthest end from the turntable 3;

[0042] A connecting rod 66 is fixed to one side of the mounting frame 62, and a blocking rod 76 is fixed to the sliding rod 72. When the sliding rod 72 slides in the direction away from the turntable 3, it can contact the blocking rod 76 and drive the block 63 on the mounting frame 62 to leave the gear 52; and when the arc top of the arc-shaped boss 32 contacts the roller 74, the block 63 just disengages from the gear 52. At this time, the bottle body 4 is located directly below the outlet of the guide tube 2, thereby achieving: only when the bottle body 4 is located directly below the outlet of the guide tube 2, the flipping freedom of the flap 51 can be released to avoid leakage.

[0043] Working principle:

[0044] By setting a necking angle adjustment component 5 at the outlet of the guide tube 2, and setting two flaps 51 that can be synchronously flipped in the opposite direction in the necking angle adjustment component 5, the necking size at the outlet of the guide tube 2 can be adjusted to adapt to the guided filling of vitamin tablets of different sizes, and prevent the necking from getting stuck when filling vitamin tablets of larger sizes; and after the filling is completed, the outlet of the guide tube 2 can be closed. By setting a locking component 6 on the guide tube 2 to limit the flipping adjustment of the flap 51, and setting a trigger component 7 to associate the rotation position of the turntable 3 with the locking action of the locking component 6, the flipping timing of the flap 51 can be controlled, so that when the bottle body 4 does not move to the bottom of the outlet of the guide tube 2, the adjustment of the flap 51 can be limited, so that the flap 51 always keeps the outlet of the guide tube 2 closed to avoid leakage.
