[0029] like Figure 1 As shown, the feeding device of the embodiment of the utility model includes a vibration plate feeding mechanism 1, a screw feeding mechanism 2, an auxiliary feeding hopper 3 and a high-speed rotary feeder 4, and the outlet end of the vibration plate feeding mechanism 1 and the outlet end of the screw feeding mechanism 2 are respectively arranged above the inlet end of the auxiliary feeding hopper 3.

[0030] The high-speed rotary feeder 4 includes a first motor 5, a material dividing shell 6 and a material dividing assembly.

The outlet end of the auxiliary feed hopper 3 is connected to the material dividing shell 6.

[0031] The material distribution housing 6 includes a housing inlet end 9 and a housing outlet end 10 . The housing inlet end 9 is arranged above the rotating shaft 7 and connected to the outlet end of the auxiliary feed hopper 3 . The housing outlet end 10 is arranged below the rotating shaft 7 .

[0032] The vibrating plate feeding mechanism 1 is preferably a vibrating plate feeder, and the screw feeding mechanism 2 is preferably a screw conveyor or a screw feeder. The material distribution space is used to hold the material. The first motor 5 rotates to drive the rotating shaft 7 to rotate. The material distribution baffles 8 are evenly distributed on the outer circumference of the rotating shaft 7. The rotating shaft 7 drives the material distribution baffles 8 to rotate. The material flows out from the auxiliary funnel and is discharged into the material distribution space through the inlet end 9 of the shell. A material distribution space is formed between two adjacent material distribution baffles 8 and the two baffles. The material distribution baffles 8 continue to rotate to rotate and transport the material in the material distribution space from the inlet end of the material distribution shell 6 to the outlet end of the material distribution shell 6. The material is re-deposited by the weight The force is discharged from the outlet end of the outer shell. The outer shell includes a top shell and a side shell. The top shell is perpendicular to the rotating shaft 7. There are two side shells, which are respectively perpendicular to the top shell. The two side shells are distributed on both sides of the rotating shaft 7. Each side shell is an arc-shaped shell. The two side shells are symmetrical with respect to the axis of the rotating shaft 7.

The first motor 5 drives the rotating shaft 7 to rotate, and the material dividing baffle 8 brings the material in the material dividing space from the shell inlet end 9 to the shell outlet end through rotation. The shell inlet end can be set directly above the shell outlet end. The shell inlet end and the shell outlet end are between the rotating shaft 7 and the material dividing baffle 8. The material falls from the shell outlet end into the former 6 below. The former 6 is filled with a plastic film.

The uniform speed feeding of light, finely crushed and fluffy materials is realized through the vibrating plate feeding mechanism 1. A plurality of dividing baffles 8 and the dividing shell 6 form a plurality of dividing spaces. The volume of each dividing space is equal. By controlling the rotation of the first motor 5 to drive the rotation of the dividing assembly, equal amount and equal time feeding are completed, high-speed starting and stopping of feeding are realized, and precise control of feeding is realized.

[0036] like Figures 2 to 5 As shown, the utility model also discloses a high-speed packaging machine, including a machine body 12, a film supply unit, a former 6, a bag sealing unit and the above-mentioned feeding device arranged on the machine body 12; the shell outlet end 10 is connected with the inlet end of the former 6, the bag sealing unit is arranged below the former 6, the film supply unit provides plastic film for the former 6, and the bag sealing unit is arranged below the outlet end of the former 6.

A plurality of material dividing baffles 8 and a material dividing shell 6 form a plurality of material dividing spaces, and the volume of each material dividing space is equal. By controlling the rotation of the first motor 5 to drive the rotation of the material dividing component, high-speed starting and stopping of feeding can be realized, and accurate control of material loading can be achieved, so that the bag sealing unit can perform uninterrupted high-speed packaging and bag sealing.

[0038] Furthermore, the bag sealing unit includes a first bag sealing roller 13 and a second bag sealing roller 14, each of which is provided with a protrusion, and the protrusion on the first bag sealing roller 13 cooperates with the protrusion on the second bag sealing roller 14 to press and seal the plastic film.

[0039] It also includes a bag sealing roller bracket 15, which is used to support the first bag sealing roller 13 and the second bag sealing roller 14. The bag sealing rollers can be driven to rotate by a motor. The protrusion on the first bag sealing roller 13 is opposite to the protrusion on the second bag sealing roller 14. The first bag sealing roller 13 and the second bag sealing roller 14 rotate relative to each other, and the two opposite protrusions engage with each other to complete the compression sealing of the periphery of the plastic bag.

[0040] The first bag sealing roller 13 and the second bag sealing roller 14 are driven to rotate by a motor. The motor drives the first bag sealing roller 13 and the second bag sealing roller 14 to rotate through the transmission of gears. The rotary bag sealing unit has two functions. The first is to press the three sides of the packaging bag and seal the packaging bag to form a bag. The other function is to feed the packaging bag film at the required speed while forming the bag.

When it senses that the paper feeding sensing rod 18 reaches a position relative to the sensor, the driving roller 17 motor rotates, driving the driving roller 17 to rotate, and then drives the plastic film to be fed into the former 6. The former 6 rolls the plastic mold into a barrel shape and then the first bag sealing roller 13 and the second bag sealing roller 14 seal the bag.

This is the basis for the bag material packaging machine to achieve high-speed operation.

[0047] After the first bag sealing roller 13 and the second bag sealing roller 14 seal the bag, the products are connected together and cut by a swinging knife mechanism. The swinging knife is directly driven by a motor and a gear to achieve high-speed operation.

[0048] Furthermore, it also includes a PLC control unit, which is connected to the feeding device, the film feeding unit, the bag sealing unit and the cutting unit 21 respectively to control the operation of the above devices or units.

[0049] The main program of the high-speed packaging machine adopts PLC control operation mode, and the control interface is installed on the touch screen. The control program coordinates the operation of each part well to achieve the purpose of high-speed production.

[0050] The packaging machine of the utility model has the following working principle: the vibration plate feeding mechanism and the screw feeding mechanism respectively operate to provide materials to the auxiliary hopper, the materials enter the high-speed rotary feeder through the auxiliary feeding hopper, and then the high-speed rotary feeder performs material distribution, the material distribution baffle in the high-speed rotary feeder distributes the materials into the former 6 below it, the driving roller motor drives the driving roller to rotate, and provides plastic film for the former, the former rolls the plastic film into a barrel shape, the materials enter the barrel-shaped plastic film, and then the bag sealing unit bags the barrel-shaped plastic film containing the materials, and the bags become continuously packaged finished products after sealing, and the cutting unit separates the continuously packaged finished products according to a uniform and specified length, and the separated products are finished products.
