[0002] After the medicinal materials are processed, they are usually packed in smaller bags according to a certain weight for easy distribution. At present, when filling, the medicinal materials are weighed first, and then the bags are transferred by a rotating packaging device. During the transfer process, the bag mouth is opened and the medicinal materials are put in. However, this packaging method has the problem of medicinal materials spilling when the bags are not opened enough, which affects the packaging effect of the medicinal materials. Utility Model Content

[0003] The utility model provides a feeding head for packaging, which solves the shortcomings of the prior art and the problem of medicinal materials being scattered when the medicinal materials are packaged, and has strong practicality.

A pair of guide rods are respectively provided at the lower ends of the two sides of the containing bucket, and a movable head is sleeved on the guide rod, and an opening and closing plate is installed at the lower end of the movable head, and an opening and closing cover is provided at the inner end of the opening and closing plate, and a propping rod is provided on the outer wall of the opening and closing cover, and the propping rod is passed through the inclined hole, and a pair of opening plates are respectively provided on the opening and closing cover. When the movable plate moves upward, it will act on the propping rod through the inclined hole, so that the opening and closing cover will open, and when the opening and closing cover is opened, the opening of the packaging bag will be propped open by the opening plate, and at the same time, the medicinal materials located in the opening and closing cover will enter the packaging bag, so as to facilitate and accurately put the medicinal materials into the packaging bag.

[0006] Furthermore, the bottom of the opening and closing cover is inclined, and the lower end thereof extends inwardly, so as to facilitate the complete introduction of the medicinal materials and enable the medicinal materials to naturally accumulate at the inner lower end of the opening and closing cover.

[0007] Furthermore, the lower end of the opening plate is a wedge-shaped structure, which facilitates the opening plate to be inserted into the packaging bag with the bag opening slightly opened.

[0008] Furthermore, a lower rack is installed on the opening and closing plate, a gear is meshed on the lower rack, the gear is installed on the containing bucket through a rotating seat, an upper rack is meshed on the upper end of the gear, an upper baffle is installed on the upper end of the upper rack, and the upper baffle is inserted on the containing bucket. The upper baffle can be used to close the bucket during the feeding operation, so as to facilitate the feeding of medicinal materials again, thereby realizing the rapid feeding and filling operation of medicinal materials.

[0009] The advantages of the above technical solution are:

[0010] The utility model is convenient for packaging and placing medicinal materials, and can prevent the medicinal materials from being scattered during the placing process, and improves the efficiency of medicinal material packaging by placing and loading materials at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0012] Figure 1 The three-dimensional structure of one embodiment is shown Figure 1 .

[0013] Figure 2 An enlarged view of A is shown.

[0014] Figure 3 The three-dimensional structure of one embodiment is shown Figure 2 . DETAILED DESCRIPTION

[0015] like Figures 1 to 3 As shown, a feeding head for packaging includes a containing bucket 1, a cylinder 2 is installed on one side of the containing bucket 1, a movable frame 3 is installed on the movable end of the cylinder 2, the movable frame 3 is sleeved on the containing bucket 1, and movable plates 5 are installed on both ends of the movable frame 3. A pair of inclined holes 50 are opened on the movable plate 5, and the upper ends of the inclined holes 50 extend inwardly. A pair of lugs 51 are provided at the lower end of the movable plate 5, and a suction nozzle is provided on the inner wall of the lug 51.

[0016] A pair of guide rods 4 are respectively provided at the lower ends of both sides of the containing bucket 1, and a movable head 40 is sleeved on the guide rods 4. An opening and closing plate 41 is installed at the lower end of the movable head 40, and an opening and closing cover 42 is provided at the inner end of the opening and closing plate 41. The lower bottom of the opening and closing cover 42 is inclined, and its lower end extends inwardly. A propping rod 43 is provided on the outer wall of the opening and closing cover 42, and the propping rod 43 passes through the inclined hole 50. A pair of opening plates 44 are respectively provided on the opening and closing cover 42, and the lower end of the opening plate 44 is a wedge-shaped structure.

[0017] A lower rack 6 is installed on the opening and closing plate 41, and a gear 60 is meshed on the lower rack 6. The gear 60 is installed on the containing bucket 1 through a rotating seat 61. The upper end of the gear 60 is meshed with an upper rack 62. An upper baffle 63 is installed on the upper end of the upper rack 62. The upper baffle 63 is inserted into the containing bucket 1.

[0018] When the present embodiment is in operation, the medicinal materials weighed by the automatic weighing device are transferred into the containing bucket 1, and when they are put in, the upper baffle 63 is in a closed state, and the medicinal materials previously put in will fall into the opening and closing cover 42 due to the opening of the upper baffle 63.

[0019] Then, the packaging bag is transferred with the bag opening facing upward to between the suction nozzles by the transfer device, and then the packaging bag is adsorbed by the suction nozzle, and the bag opening of the packaging bag is slightly opened during adsorption.

[0020] Thereafter, the cylinder 2 is started, and the movable frame 3 moves upward under the drive of the cylinder 2, and the movable plate 5 moves upward with the upward movement of the movable frame 3. During the movement, the packaging bag moves upward accordingly, and the lower end of the opening plate 44 is inserted into the packaging bag.

[0021] And when the movable plate 5 moves upward, it will act on the propping rod 43 through the inclined hole 50, so that the propping rod 43 and the opening and closing cover 42 move outward, and when moving outward, the bag mouth of the packaging bag will be opened to a certain extent through the opening plate 44. At the same time, as the opening and closing cover 42 is opened, the medicinal materials inside will move downward into the packaging bag. At the same time, as the opening and closing cover 42 moves outward, the upper baffle 63 will move inward until it is closed. After closing, the feeding device puts the medicinal materials into the containing bucket 1 and waits for the filling operation to be performed again.

[0022] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
