[0042] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0043] First embodiment

[0044] like Figure 1As shown, it is a schematic diagram of the structure of the quantitative packaging device for corn seeds of the utility model. In this embodiment, the quantitative packaging device is provided with an automatic quantitative packaging scale 10, a bracket 20, a conveying structure 30, a positioner and a sealing machine 40. A support frame 60 is provided at the bottom of the conveying structure 30. The support frame 60 is used to place the conveying structure 30 on a plane. The bracket 20 is fixed on the automatic quantitative packaging scale 10, and the sealing machine 40 is fixed on the bracket 20. The conveying structure 30 is located in front of the automatic quantitative packaging scale 10, and the positioner is located between the automatic quantitative packaging scale 10 and the sealing machine 40. Figure 2 As shown, the conveying structure 30 is provided with a conveyor belt 31 and positioning plates 32 located on both sides of the conveyor belt 31. The positioner is fixed on the positioning plate 32. The positioner is composed of two symmetrical positioning structures 50. Please continue to refer to Figure 2 As shown, the positioning structure 50 of this embodiment is provided with a mounting plate 51, a plug-in plate 52 and a fixing plate 53. The fixing plate 53 includes a first clamping plate 531, a connecting plate 532 and a second clamping plate 533. The distance between the two first clamping plates 531 in the two positioning structures 50 is greater than the distance between the two second clamping plates 533, thereby forming a shape with the external port of the first clamping plate 531 as the maximum opening and the external port formed by the second clamping plate 533 as the minimum opening.

[0045] Please continue reading Figure 2 The bolt 513 is located in the card slot 512 and is used to fix the plug board 52 in the slide slot 511 of the mounting plate 51.

[0046] During the use of the quantitative packaging device for corn seeds of the present embodiment, firstly, the height of the two fixing plates 53 of the positioner is adjusted according to the above requirements, and the height is required to be only slightly lower than the height of the packaging bag. The corn seeds after weighing are dropped into the packaging bag through the automatic quantitative packaging scale 10, and then the packaging bag automatically falls on the conveyor belt 31 below it. As the conveyor belt 31 moves, the packaging bag first passes through the positioner. Specifically, the bag mouth of the packaging bag first passes between the two first clamping plates 531 of the two positioning structures 50, and then passes between the two connecting plates 532. Since the two connecting plates 532 form a structure with a gradually shortened distance, when finally passing through the second clamping plate 533, the bag mouth of the packaging bag has been flattened into a nearly flat structure. The flattened bag mouth is finally sealed by the sealing machine 40. In this process, the staff does not need to tidy up the bag mouth so that it can enter the sealing machine 40, thereby eliminating the steps of manual operation and saving some manpower.

[0047] Second embodiment

[0048] See also Figure 3 As shown, it is a structural schematic diagram of the second embodiment of the utility model. The corn seed quantitative packaging device in this embodiment is also provided with a lifting device 70. The lifting device 70 is provided with a first connecting rod 71 and a second connecting rod 72 parallel to each other, and a folding rod 73 located between the first connecting rod 71 and the second connecting rod 72. The structure of the folding rod 73 is an existing folding structure, specifically, a plurality of rod bodies are connected by hinges or shaft connections to form a folding structure with a poor shape. It should be noted that the folding rod 73 in this embodiment has a certain damping effect, that is, there is a certain resistance between the plurality of rod bodies in the folding rod 73, and the shape or form can be maintained without change without external force.

[0049] Please continue reading Figure 3 As shown, the upper end surface of the first connecting rod 71 and the lower end surface of the second connecting rod 72 are provided with a locking groove 74, and sliders 75 are provided at the four top corners of the folding rod 73. The sliders 75 are respectively located in the locking grooves 74 of the first connecting rod 71 or the second connecting rod 72. In other embodiments, handles 721 are provided at both ends of the second connecting rod 72.

[0050] See also Figure 1 , Figure 3 and Figure 4As shown, during use, the quantitative packaging device for corn seeds of this embodiment is different from the previous embodiment in that a lifting device 70 is added to the structure of the positioner in this embodiment. During use, the handle 721 is first pulled upward, and the two sliders 75 above the folding rod 73 and the two sliders 75 below are moved toward the middle in their corresponding positioning grooves 74, and then the folding rod 73 is longitudinally elongated, and then the height of the second connecting rod 72 is adjusted to adapt to the limiting position of packaging bags of different heights to prevent them from tipping over. The addition of the lifting device 70 plays a certain auxiliary role in fixing the bag mouth of the packaging bag by the positioner, and can further stabilize the packaging bag. In addition, the lifting device 70 also facilitates the sealing work of the sealing machine 40.

[0051] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
