An anti-sticking layer is provided on the surface. The weighing sensor 33 is installed in the middle section of the transmission shaft 32. The transmission shaft 32 is coaxially connected to the transmission shaft of the mechanical speed change device 62. A shield 4 is installed around the cross-feeding plate 31 of the weighing assembly 3, a window is opened through the center of the top plate, and a weighing assembly 3 is opened on the rear side plate. The transmission shaft and the sliding baffle 55 of the reciprocating material blocking mechanism 5 pass through the window; during the rotation of the weighing component 3, the conveyor belt 1 will continue to drop materials, and the reciprocating material blocking device 5 will move synchronously with the weighing component 3.

[0037] Preferably, the weighing sensor 33 of the present invention is a pin-type weighing sensor, and may also be a photoelectric weighing sensor or a digital weighing sensor.
[0038] The driving assembly 6 includes a mechanical speed change device 62 and a driving member 61 . The driving member 61 is installed behind the mechanical speed change device 62 as a power source.
[0039] The shield 4 is installed on the outside of the cross feeding plate 31 to prevent the material from splashing during feeding.
[0040] For easy observation Figure 1 Structure, wherein one side of the shield 4 is not shown.
[0041] The driving assembly 3 comprises a mechanical speed change device 62 and a driving member 61 . The mechanical speed change device 62 transmits power to the power output end through a first-stage speed change. The driving member 61 is installed behind the mechanical speed change device 62 as a power source.
[0042] Preferably, the mechanical speed change device 22 of the present invention is a gearbox, and may also be a chain drive or a toothed belt drive.
[0043] The transmission ratio of the gearbox is 2:1, and the driving member 61 rotates 180 degrees and the weighing component 3 rotates 90 degrees. The transmission ratio of the gearbox to the reciprocating material blocking device 5 is 1:2, and the driving member 61 rotates 180 degrees and the eccentric circle 51 of the reciprocating material blocking device 5 rotates 360 degrees.
[0044] Preferably, the driving member 21 of the present invention is a servo motor, and may also be a stepping motor or a three-phase asynchronous motor.
[0045] The specific feeding process of the utility model is:
[0046] The conveyor belt 1 transports the material to the material channel 2, and the material channel 2 falls onto the cross loading plate 31 after being collected and concentrated. The weight of the material on the cross loading plate 31 increases, and the weighing sensor 33 installed in the middle section of the transmission shaft 32 of the weighing assembly 3 produces elastic deformation, and the resistance change produces an electrical signal. When the weight of the material reaches the preset threshold, the driving member 61 starts, and the mechanical speed change device 62 transmits the torque. The cross loading plate 31 and the reciprocating baffle mechanism 5 act synchronously, and the cross loading plate 31 rotates 90 degrees, and the eccentric circle 51 in the reciprocating baffle mechanism 5 rotates 360 degrees. The eccentric circle 51 drives the connecting rod to move, and the moving rod of the slide baffle 55 slides along the slide 56. After the extension is completed to catch the material that will continue to fall, the cross loading plate 31 completes the rotation of 90 degrees and the sliding baffle 55 is pulled back to complete, returning to the original position, completing the cycle, and realizing high-speed and accurate loading.
[0047] See also Figure 1 and Figure 3 Shown Figure 2 The enlarged view of the portion A in the middle includes an eccentric circle 51 , an active connecting rod 52 , a driven connecting rod 53 , a fixed sliding sleeve 54 , a sliding baffle 55 , and a slideway 56 . The sliding baffle 55 is connected to the slideway 56 in a sliding manner. When it is not in motion, it is located behind the shield 4 and is perpendicular to the shield 4. When the driving member 61 receives the signal to move, the eccentric circle 51 rotates to drive the connecting rod mechanism, and the connecting rod mechanism converts the circular motion into a linear reciprocating motion. When the eccentric circle 51 rotates 180 degrees, the sliding baffle 55 is pushed out to the farthest end along the arc side of the slideway 56, covering the discharge port of the material channel 2 to catch the falling material. The eccentric circle 51 continues to rotate, and the connecting rod mechanism pulls the sliding baffle 55 back along the straight side of the slideway 56. Because the straight side of the slideway 56 is perpendicular to the material channel 2, the material will be scraped away from the sliding baffle 55 by the material channel 2 when the sliding baffle 55 moves, and the material continues to go down to the cross loading plate 31. When the eccentric circle 51 rotates 360 degrees, the sliding baffle 55 slides to the nearest end and is perpendicular to the shield 4 again, completing a cycle.
[0048] See also Figure 4 The isometric structural diagram of the weighing assembly of the utility model is shown, including a cross-loading plate 31, a transmission shaft 32 and a weighing sensor 33. When the material falls onto the cross-loading plate 31, the weighing sensor 33 installed on the transmission shaft 32 generates elastic deformation and the resistance change reaches a preset threshold, and the signal is transmitted to the driving member 61.
[0049] See also Figure 5 The isometric structural diagram of the drive assembly of the utility model is shown, including a drive member 61 and a mechanical speed change device 62. The drive member 61 is installed behind the mechanical speed change device 62 as a power source. The drive member 61 receives a signal from the weighing sensor 33, the drive member 61 is started, and the mechanical speed change device 62 changes the power and transmits it to each moving part.
[0050] See also Figure 6 The schematic diagram of the cross-sectional structure of the slide 56 of the reciprocating material baffle mechanism of the utility model is shown, including the slide 56, the non-return movable part 561 and the spring 562. The slide 56 includes a horizontal track and a curved track. One group of non-return movable parts 561 and the spring 562 are located at a position that can support the sliding baffle when the sliding baffle slides to the farthest end of the curved track, so that the sliding baffle enters the horizontal track from the curved track, and the other group of non-return movable parts 561 and the spring 562 are located at a position that can allow the sliding baffle to enter the curved track when it slides to the nearest end of the horizontal track; when the sliding baffle of the material baffle 55 passes through the non-return movable part 561, the non-return movable part 561 is pressed down, the spring 562 is compressed, and the sliding baffle passes through the spring 562 and rebounds, and the non-return movable part 561 returns to its original position, thereby preventing the material baffle 55 from repeating the slide movement on one side.
[0051] In summary, the utility model provides a feeding device for a packaging machine. The conveyor belt 1 continuously feeds materials, and through the synchronous movement of the reciprocating material blocking device 5 and the weighing component 3, the falling materials during the rotation of the weighing component 3 will be caught by the reciprocating material blocking device 5 when passing through the material channel 2, thereby ensuring the accuracy of feeding. At the same time, the weighing component 3 can synchronize feeding and weighing, thereby significantly improving the efficiency of packaging work.
