[0043] The feeding unit 4 is arranged at one side of the material conveying unit 3, and comprises a material loading plate 41, a material loading cylinder 42, a material pushing rod 43 and a material pushing cylinder 44. Specifically, the material loading plate 41 is arranged upstream of the second conveying belt 33, and the plate surface is flush with the second conveying surface and extends in the second direction. The material loading cylinder 42 is a cylinder body arranged at one side of the material loading plate 41 close to the second conveying belt 33, and extends in a third direction, so that a plurality of materials can be stacked. A through slot 421 is formed in the bottom of the material loading cylinder 42 for passing a single material, and the outlet of the through slot 421 is directed towards the second conveying belt 33 and communicates with the second conveying surface.

The baffle 52 is arranged above the second conveying belt 33 and has a baffle surface parallel to the second conveying surface. Preferably, a guide inclined surface 521 is formed on the side of the baffle 52 facing the upstream side of the second conveying belt 33 and is inclined to the side of the discharging chute 51, so as to guide the unqualified materials to be discharged. The sensor 53 is arranged in front of the baffle 52 along the first direction.

Correspondingly, the baffle 52 has two states of blocking and releasing. According to the detection information of the sensor 53, the baffle 52 can be in a blocking state of blocking and guiding the materials to be discharged or in a releasing state of releasing the materials. When the sensor 53 detects that the materials are unqualified products, the baffle 52 is in the blocking state, and when the sensor 53 detects that the materials are qualified products, the baffle 52 is in the releasing state. Specifically, the baffle 52 can be lifted along the third direction, rotated horizontally around an axis parallel to the third direction or translated along the first direction, and the like, so as to switch between the blocking state and the releasing state.

Specifically, the rotary air cylinder 61 is fixedly installed on the tabletop of the practical training table 1, and the output shaft thereof extends along the third direction. The connecting plate 62 is connected with the output shaft of the rotary air cylinder 61, can rotate with the output shaft of the rotary air cylinder 61 around the third direction, and the plate surface of the connecting plate 62 is parallel to the tabletop of the practical training table 1.

The first pneumatic suction cup 64 and the second pneumatic suction cup 65 are fixedly installed at the two ends of the connecting rod 63 respectively and face the first conveying belt 23 and the second conveying belt 33 respectively. In the third direction projection, the suction centers of the first pneumatic suction cup 64 and the second pneumatic suction cup 65 coincide with the centers of the first groove 261 and the second groove 361 respectively. Meanwhile, in the extension direction of the connecting rod 63, the distances from the suction centers of the first pneumatic suction cup 64 and the second pneumatic suction cup 65 to the center of the connecting rod 63 are equal.

[0046] The working principle of the filling unit 6 is that when the second pneumatic suction cup 65 is adsorbed to the material on the material conveying unit 3, the rotary air cylinder 61 drives the connecting plate 62 to rotate by 180°, so that the material adsorbed by the second pneumatic suction cup 65 is located above the container on the container conveying unit 2. The second pneumatic suction cup 65 releases the material, so that the material falls into the container, and the filling is completed. Meanwhile, the first pneumatic suction cup 64 adsorbs the next material on the material conveying unit 3, and the next working cycle is performed.

[0047] Preferably, in the third direction projection, a lug 622 is protrudingly arranged on the side surface of the connecting plate 62 along the radial direction of the rotation shaft. First and second limiting blocks 66 and 67 are also protrudingly arranged on the plate surface of the rotary air cylinder 61 where the connecting plate 62 is located. When the second pneumatic suction cup 65 is located above the material conveying unit 3, the lug 622 is limited by abutting against the second limiting block 67. When the rotary air cylinder 61 drives the connecting plate 62 to rotate, so that the second pneumatic suction cup 65 is located above the container conveying unit 2, the lug 622 is limited by abutting against the first limiting block 66. Through the limiting cooperation of the first and second limiting blocks 66 and 67 and the lug 622, the two stations of the rotary air cylinder 61 are more simply determined, and the control logic is simplified. Preferably, in the third direction projection, the first and second limiting blocks 66 and 67 are separated by 180° and are located on the opposite sides of the radial direction of the connecting plate 62 respectively.

[0048] The control unit 7 is arranged on the practical training platform 1, and comprises a touch screen 71, control buttons 72 and a PLC controller (not shown in the figure), wherein the PLC controller is electrically connected with the container conveying unit 2, the material conveying unit 3, the feeding unit 4, the discharging unit 5 and the filling unit 6 respectively. The touch screen 71 and the control buttons 72 are electrically connected with the PLC controller, and a user can control each working step of the material filling teaching equipment provided by the application by operating the touch screen 71 and the control buttons 72.

[0049] The alarm lamp 8 is installed at a corner of a table top of the practical training platform 1 and is electrically connected with the PLC controller. The alarm lamp 8 can display three states of red, yellow and green, and the three states correspond to three different states of device failure, device maintenance adjustment and normal working respectively, so as to help a user quickly judge the working state of the device.

[0050] The working principle of the material filling teaching equipment provided by the application is as follows: the height of the material conveying unit 3 is adjusted, so that the plane where the second conveying surface is located is above the container on the first conveying surface. The feeding unit 4 supplies material to the material conveying unit 3, and the material is transported on the second conveying surface. When the material passes through the sensor 53, the sensor 53 detects the material, divides the material into qualified products or unqualified products according to a preset standard, and if the material is a qualified product, the material is moved to the second limiting plate 36 at the end along the second driving belt and is fixed, and meanwhile, the container is moved to the first limiting plate 26 at the end along the first conveying belt 23 and is fixed. The first pneumatic suction cup 64 and / or the second pneumatic suction cup 65 adsorb the material, the rotary air cylinder 61 rotates 180°, so that the material is transferred above the container, the first pneumatic suction cup 64 and / or the second pneumatic suction cup 65 release the material, and the material falls into the container to complete filling. If the material is an unqualified product, the baffle 52 is moved to the movement track of the material, so as to guide the unqualified material into the discharging groove 51.
