[0002] Blueberry is the fruit of a perennial low shrub of the genus Vaccinium in the Ericaceae family. It is native to North America and East Asia, and is distributed in Korea, Japan, Mongolia, Russia, Europe, North America, Heilongjiang, Inner Mongolia, Changbai Mountain in Jilin and other countries and regions in China. It grows in areas with an altitude of 900 to 2300 m. In addition to the conventional sugar, acid and Vc, blueberry fruits are rich in VE, VA, VB, SOD, arbutin, protein, anthocyanin, edible fiber and rich mineral elements such as K, Fe, Zn, Ca, etc.

[0003] In the weighing and packaging process of blueberries, mechanized weighing equipment is generally set up to weigh and pack blueberries. Due to the high value of blueberries, the general weighing equipment is not very accurate in controlling the precision of its gram weight, resulting in a large difference in the gram weight of each box of blueberries during the weighing and packing process. First, it affects the company's processing and production quality control, and second, it brings a bad consumption experience to consumers. Therefore, in view of these current situations, it is urgent to develop a dual-channel blanking weighing mechanism to meet the needs of actual use. Summary of the invention

DETAILED DESCRIPTION

[0013] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings. Example

[0014] See also Figure 1-6 The double-channel blanking weighing mechanism specifically implemented includes a frame 1, a hopper 2 and a weighing sensor 3. A first channel 11 and a second channel 12 are provided on the top of the frame 1. The first channel 11 and the second channel 12 are arranged in a parallel structure. A feeding mesh belt 13 is provided inside the first channel 11 and the second channel 12. A detachable limit block 121 is also provided inside the second channel 12. The hopper 2 is arranged at one end of the first channel 11 and the second channel 12. A horizontally retractable plug-in board 21 is also provided inside the hopper 2. The hopper 2 can form an openable and closable conductive structure through the plug-in board 21. The weighing sensor is arranged inside the frame 1, and the plug-in board 21 is movably connected to the weighing sensor 3 through a horizontal moving component.

[0015] A dual-channel feeding structure is adopted, and a limit block 121 for only moving a single material is provided in the second channel 12. A large range of materials can be fed into the hopper 2 through the first channel 11, and the packaged weight is approached to below the critical value. Then, a single material is continuously transported through the second channel 12 until the weight is within the tolerance range. This can achieve the effect of alternating large-scale and small-scale material dropping, and has the characteristic of small weight deviation, which is beneficial to the precise control of the weight of blueberries in the weighing and packaging process.

[0016] Specifically, Figure 2-3As shown, the horizontal moving assembly includes a support arm 5 and a driving member. One end of the support arm 5 is connected to the weighing sensor 3, and the other end of the support arm 5 is fixedly connected to the hopper 2. The hopper 2 is suspended below the ends of the first channel 11 and the second channel 12 through the support arm 5. The driving member is used to control the horizontal movement of the plug-in board 21. A linear slide rail 51 is provided on the top surface of the support arm 5. The plug-in board 21 is movably connected to the linear slide rail 51. The plug-in board 21 can slide along the axial direction of the support arm 5 through the linear slide rail 51.

[0017] Preferably, the driving member can be composed of a cylinder 4, one end of which is a horizontally movable cylinder shaft 41, the end of the cylinder shaft 41 is provided with a buckle joint 42, and the end of the plug-in board 21 close to the cylinder shaft 41 is provided with a buckle seat 22, and the end of the cylinder shaft 41 is connected to the buckle seat 22 through the buckle joint 42.

[0018] In a further solution, a magnetic attraction fitting component 6 is provided between the plug-in board 21 and the outer side wall of the hopper 2, and the magnetic attraction fitting component 6 includes a magnetic attraction block 61 and an inductive suction sheet 62. The magnetic attraction block 61 is arranged on the outer side wall of the hopper 2 close to the buckle seat 22, and the inductive suction sheet 62 is arranged at the end of the buckle seat 22 away from the buckle joint 42. When the plug-in board 21 extends to the inside of the hopper 2 through the cylinder shaft 41, the magnetic attraction block 61 and the inductive suction sheet 62 are inductively adsorbed, and the middle part of the buckle joint 42 is an inwardly concave buckle groove 421, and the thickness of the buckle groove 421 is greater than the wall thickness of the buckle seat 22. When the plug-in board 21 extends to the inside of the hopper 2 through the cylinder shaft 41, the buckle joint 42 is radially separated from the buckle seat 22 by the magnetic attraction fitting component 6. When the plug-in board 21 extends to the inside of the hopper 2 through the cylinder shaft 41, due to the inductive adsorption of the magnetic block 61 and the inductive suction sheet 62, the plug-in board 21 will continue to move toward the side of the hopper 2 under the action of magnetic adsorption. At the same time, the thickness of the buckle groove 421 is greater than the wall thickness of the buckle seat 22, and the buckle seats 22 can be radially separated from each other, so that the cylinder shaft 41 and the hopper 2 are in a non-contact state. At this time, the weight of the hopper 2, the plug-in board 21 and the internal material can completely act on the support arm 5, which can reduce the influence of the cylinder shaft 41 on the supporting force of the plug-in board 21, so that the weight measured by the weighing sensor 3 is more accurate.
