The conveying mechanism 1 is connected with a sorting mechanism 2, and the sorting mechanism 2 and the identification module separate products. In order to facilitate the subsequent packaging, the sorting mechanism 2 is respectively provided with a sorting mechanism 3 for ensuring the orderly arrangement of the products, wherein the sorting mechanism 3 expands according to the production line requirement, and the sorting mechanism 2 is also adaptively adjusted. And a buffer mechanism 4 and a return mechanism 5 opposite to the transmission mechanism 1 are arranged between the sorting mechanism 2 and the sorting mechanism 3, and when the sorting mechanism 3 finds abnormal conditions in the product arrangement process, the buffer mechanism 4 ensures that the transmission mechanism 1 and the sorting mechanism 2 normally operate in a stop state of the sorting mechanism 3, and the return mechanism 5 and the identification module are matched to reject abnormal products.

Specifically, the conveying mechanism 1 in the application comprises a horizontal or inclined feeding frame 11, and a conveying belt 12 driven and controlled by a servo motor is arranged at the top of the feeding frame 11, similar to the existing belt conveying structure. The two sides of the transmission belt 12 are provided with the opening and closing components 6 which can adjust the transmission area of the transmission belt 12, the transmission belt 12 is provided with the material blocking component 7 adjacent to the opening and closing components 6, when the product is contacted with the material blocking component 7, the product stops, but the product at the upstream of the transmission mechanism 1 can still continue to be transmitted, when the product interval is adjusted to a specified distance, the material blocking component 7 is reset, and the product is normally fed on the transmission belt 12.

In depth, the opening and closing assembly 6 in the present application includes support plates 61 disposed at both sides of the conveyor belt 12 to limit the products; the supporting plate 61 is provided with equidistant open-close grooves 62, an open-close block 63 is movably arranged in the open-close grooves 62, an elastic reset piece is arranged between the open-close block 63 and the open-close grooves 62, one end of the open-close block 63 opposite to the conveying belt 12 is fixedly provided with a push plate, the other end of the open-close block is connected with a traction rope 64, the traction rope 64 is in transmission connection with a traction wheel 65 and in transmission connection with an electric push rod 66, and a sealing strip 67 made of flexible materials is connected between the push plates of the open-close block 63. Under the normal state, the opening and closing blocks 63 are subjected to the pulling moment of the pulling rope 64, the oppositely arranged opening and closing blocks 63 are in a relatively far-away state, when the flow of the transmission mechanism 1 needs to be reduced, the pulling rope 64 is loosened, the opening and closing blocks 63 are mutually close under the action of the elastic reset piece, and the closing strips 67 between the pushing plates of the opening and closing blocks 63 are relatively close. Because the electric push rods 66 which are in transmission connection with the opening and closing blocks 63 which are oppositely arranged in each group are independently driven, peristaltic change can be carried out on the channels between the closing strips 67, so that products are guided to be uniformly transmitted, the products are assisted in packaging and adjusting the direction of the products, the box packaging machine has good position correction effect on the box packaging, and subsequent sorting is facilitated.

Further, the existing material blocking mode usually stops the conveying mechanism 1 completely, but this mode leads to the reduction of the overall production efficiency of the production line. The material blocking assembly 7 comprises a material blocking frame body 71 arranged on the inner side of a conveying belt 12, wherein the material blocking frame body 71 is movably provided with a pair of openable cover plates 72, the cover plates 72 are attached to the upper end of the conveying belt 12, and a corresponding material blocking structure is arranged below the cover plates 72. The material blocking frame 71 is internally and movably provided with a material blocking guide roller 73 and tensioning guide rollers 74 arranged on two sides of the material blocking guide roller 73, and the material blocking guide roller 73 and the tensioning guide rollers 74 are in transmission connection with the conveying belt 12.

When the material blocking guide roller 73 and the tensioning guide roller 74 move, the cover plate 72 is also separated into the material blocking guide roller 73, so that a movable space is reserved.

When the product is required to be prevented from travelling, the material blocking guide roller 73 is lifted under the action of the lifting rack 75 and the lifting gear 76, the tensioning guide roller 74 is lowered along with the lifting rack and keeps the tensioning state of the conveyor belt 12, and when the tensioning guide roller 74 moves to the position above the horizontally arranged conveyor belt 12, the conveyor belt 12 attached and pressed with the tensioning guide roller 74 is adjusted to be in a vertical state along with the tensioning guide roller, and the vertically arranged conveyor belt 12 blocks the product from travelling.

Still further, existing products are typically sorted manually, but this approach is time consuming and labor intensive and increases overall production costs, thus introducing an identification module for automatic identification.

Each first driving rod 22 and each second driving rod 23 are in independent transmission connection with different driving motors, when the sensing assembly senses that the product is applied to the pressure of the diversion channel 21, the first driving rod 22 or the second driving rod 23 rotates, and the driving strips 24 on the surface guide the product to deviate to a designated position in the sliding process of the product. When the first driving rod 22 and the second driving rod 23 rotate synchronously, the driving moment applied to the bottom of the product by the driving strips 24 on the surfaces of the driving rods keeps balanced, and the product moves along a straight path at the moment, and if a rotating speed difference exists, the product shifts.

In addition, in order to increase the sensing range of the sensing assembly, the sensing assembly comprises a plurality of groups of sensing strips 25 in a strip shape, the sensing strips 25 are provided with sensing ridges 26 inserted between the first driving rod 22 and the second driving rod 23, and an elastic block 27 and a pressure sensor are arranged at the lower end of the sensing strips 25. As the product moves over the diversion channel 21 it contacts the sensing ridge 26 and the sensing strip 25 is depressed as a whole and the product orientation is sensed by the pressure sensor.

Meanwhile, auxiliary pushing is often needed in the product classification process, enough pushing moment is applied to ensure that the products are accurately positioned, the pushing component 8 comprises a pushing groove 81 arranged at the upper end of the sensing ridge 26, a pushing block 82 is movably arranged in the pushing groove 81, an air cylinder 83 with two ends communicated with an air pump is arranged in the pushing groove 81, a switching valve is arranged between the air pump and the air cylinder 83, an air block 84 is slidably arranged in the air cylinder 83, and the pushing component 8 is ensured to have enough response speed in a pneumatic driving mode.

The pushing block 82 is provided with a pushing claw 86 extending outwards relative to the pushing groove 81, and the pushing claw 86 is rotatably connected with the pushing block 82 and is provided with an elastic reset piece therebetween. When the product enters the diversion channel 21, the pushing claw 86 is contracted in the pushing block 82, and when the product is separated from the pushing block 82, the pushing claw 86 is opposite to the rear end of the product, so that pushing moment is applied.

It can be seen that the sorting mechanism 3 of different combinations is adopted for different production lines, and comprises an arrangement groove 31 which is independently arranged, a transmission chain 32 is arranged on the side surface of the arrangement groove 31 to provide a moving driving force for products, a partition rod 33 or a partition plate 34 which are equidistantly arranged is arranged on the transmission chain 32, and when the transmission chain 32 moves, the partition rod 33 or the partition plate 34 guides the products to the arrangement groove 31 one by one and is arranged. The bottom of the arrangement groove 31 is provided with an arrangement guide roller 35 for guiding the product to slide forward.
