A valve position sensor is installed on the surface of the three-way valve 4, and a high-position sensor is installed inside the storage bin 1. The valve position sensor and the high-position sensor are both electrically connected to the PLC controller.

[0022] like Figure 1As shown, take the filling of materials in the B02 silo in the figure as an example: toggle the selection switch to select the B02 silo, the corresponding Y30 valve of the three-way valve 4 is opened, the valve position sensor detects that the Y30 valve position is correct and there is no alarm, press the start button, in order to prevent the material from blocking the feeding fan 2, start and complete the purge pipeline 60 seconds after the PLC controller controls the electric unloading rotary valve 5 to start, and blow the material falling from the feeding silo 3 to the B02 silo. When the material reaches the silo high position sensor, the electric unloading rotary valve 5 stops unloading first, and the feeding fan 2 continues to purge the pipeline for 60 seconds before emptying the material pipe and then stops.

[0023] Example 2

[0024] In order to make it easier to put materials into the feeding bin 3, a further design is performed on the basis of Example 1: like Figure 2-Figure 5 As shown, a screw feeder 8 is connected to the rear of the feeding bin 3 for feeding, a feeding hopper 9 is arranged at the bottom end of the screw feeder 8, a bottom plate 11 is fixed to the bottom of the feeding hopper 9, a slide 12 is push-pull connected to the upper surface of the bottom plate 11, a lifting mechanism is arranged inside the slide 12, the lifting mechanism is connected to the lifting plate 13, and is used to lift the bagged masterbatch, and a bag breaking mechanism 10 is arranged inside the feeding hopper 9.

[0025] The lifting mechanism includes a lifting drive motor 16, a lead screw and a slider. The lifting drive motor 16 is installed on the top of the slide 12. The slider is sleeved on the outer surface of the lead screw. The lead screw and the slider are both located inside one of the supporting columns of the slide 12. A strip is opened on the surface of the supporting column, and the slider passes through the strip to connect with the lifting plate 13.

[0026] A bag breaking socket 15 is provided at the center of the surface of the lifting plate 13 .

[0027] The bag breaking mechanism 10 includes a fixed plate 103 fixed inside the feed hopper 9, and lifting components are provided at both ends of the fixed plate 103. A rotating cross bar 106 is rotatably connected between the two lifting components, and a bag breaking blade 107 is fixed at the center of the surface of the rotating cross bar 106. One of the lifting components is fixed to the rotating cross bar 106 by a fixing component 105.

[0028] The lifting assembly includes an L-shaped lifting rod 104, a first spring 102 and a fixed block 101. The fixed block 101 is located above the fixed plate 103. The L-shaped lifting rod 104 is located at the top of the fixed plate 103 and passes through the fixed plate 103 and is fixed to the lower surface of the fixed block 101. The first spring 102 is installed between the fixed plate 103 and the fixed block 101. An opening is provided on the surface of the feed hopper 9, and the bottom end of the L-shaped lifting rod 104 extends through the opening to the outside of the feed hopper 9.

[0029] A cavity is provided inside one of the fixed blocks 101, and the fixing component 105 is located inside the cavity. A fixing ring 1061 is connected to the upper and lower surfaces of one end of the rotating cross bar 106 close to the fixing component 105. The fixing component 105 includes an L-shaped fixing rod 1051 and a second spring 1052. The second spring 1052 is fixed between the L-shaped fixing rod 1051 and the inner wall of the cavity. One end of the L-shaped fixing rod 1051 penetrates into the fixing ring 1061, and the other end extends to the outside through a strip-shaped opening 1053 opened on the surface of the cavity. When in use, the bag breaking blade 107 is set upward. When it is not needed, the L-shaped fixing rod 1051 is pulled to disengage it from the fixing ring 1061, and then the rotating cross bar 106 can be flipped to make the bag breaking blade 107 face downward to avoid accidental injury.

[0030] Two auxiliary bag breaking plates 14 are fixed to the lower surface of the lifting plate 13. The two auxiliary bag breaking plates 14 are arranged on both sides of the feed hopper 9. The auxiliary bag breaking plate 14 is arranged in an arc surface at one end close to the feed hopper 9, so that when the arc surface contacts the L-shaped lifting rod 104, the L-shaped lifting rod 104 is lifted to the upper surface of the auxiliary bag breaking plate 14.

[0032] A travel switch is installed on the side wall of the slide 12 to play a role of limiting, so that the lifting plate 13 stops when it reaches a fixed height.

[0033] Working principle: During specific use, the bagged masterbatch is placed on the lifting plate 13, and the lifting drive motor 16 is started through the lifting control button to drive the lifting plate 13 to move upward. When it moves to the travel switch position, it stops moving upward. Then the operator pushes the slide 12 to push the lifting plate 13 to the top of the feed hopper 9. During the pushing, the auxiliary bag breaking plate 14 is connected to the L-shaped lifting rod 104. Under the action of the arc surface, the L-shaped lifting rod 104 is moved upward, so that the bag breaking blade 107 moves upward, piercing the bag while continuing to move the slide 12, so that the bag breaking blade 107 slides the bag, and the masterbatch can fall directly into the inside of the feed hopper 9 and be transported to the inside of the storage bin 1 by the spiral feeder 8.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
