The utility model discloses a working process and beneficial effect as follows: the whole device consists of five parts, namely a cotton feeding device, a cotton conveying device, a forming device, a net feeding device and a net cutting device. After the harvested cotton enters the cotton collecting box, the cotton is uniformly fed onto a cotton conveying belt through a cotton feeding mechanism, the cotton is conveyed into a forming bin through the conveying belt and is rolled and formed under the interaction of the forming belt and the conveying belt, a net feeding motor starts to feed the net after the forming reaches the required compactness, and a net cutting motor starts to cut the net after the net is fed; the net is cut, the door of the forming bin is opened, the cylindrical cotton bale wrapped with the cotton net falls down from the forming bin, and the forming is finished. According to the analysis and requirements of the above-mentioned key components, the whole structure of cotton circular mould forming equipment is designed, as shown in figure 1

Cotton feeding sensors 30 distributed on two sides of a cotton conveying bin body detect that cotton is fed from a cotton collecting bin, a cotton feeding device starts to uniformly feed seed cotton to a cotton conveying belt 33, a screw guide rail pair of a forming assembly 11 starts to move downwards before seed cotton is fed and formed by the cotton conveying belt 33, the seed cotton is formed in a small cavity formed by the forming belt 9 and the cotton conveying belt 33, a screw slide block 21 gradually moves downwards along with continuous feeding of the seed cotton, when a cotton mold size detection sensor 10 detects that the diameter of a cotton mold reaches the maximum, the screw guide rail pair stops moving, the seed cotton continuously enters until the forming belt 9 is abutted to the inner side of the forming cavity, finally, a roller distributed in the forming bin body compacts the cotton mold again, when a cotton mold compactness detection sensor 36 detects that the compactness of the cotton mold reaches the maximum, cotton feeding is stopped, after forming is completed, a net feeding device 13 starts to feed nets, a cotton conveying speed detection sensor 32 detects the net feeding speed, after the net feeding is finished, the net cutting device 14 starts to cut the net, and after the net cutting is finished, the bin gate hydraulic cylinder 8 pushes the formed bin 35 to unload the cotton bale, and the forming is finished.

The cotton feeding device mainly uniformly feeds seed cotton stored in the cotton collecting bin to the forming bin, the structure of the cotton feeding device is distributed as shown in figure 4, cotton clusters are accumulated at the bottom of the cotton collecting bin, in order to ensure that the cotton clusters are accumulated in the cotton collecting bin and do not enter the cotton conveying mechanism, the cotton feeding device is designed into a wheel roller with row teeth 3101, when the cotton collecting device is in a cotton collecting state, the row teeth 3101 of the cotton feeding roller are at the lowest position, the pre-compressed cotton clusters are blocked in the cotton collecting bin under the action of the row teeth 3101, when cotton needs to be fed, the cotton clusters are uniformly fed onto the cotton conveying belt along the arc line of the lower part of the cotton collecting bin by the staggered row teeth 3101, the row teeth 3101 of the cotton feeding mechanism 31 are distributed as shown in figure 5, the row teeth 3101 are distributed into three rows, the designed interval between the row teeth 3101 is 20mm, and the staggered angles are arranged in degrees.

The forming mechanism is mainly used for beating cotton conveyed by the cotton feeding mechanism 31 into round bales, the design requirement of the forming mechanism is that the compactness of the round cotton die forming is adjustable, meanwhile, in order that a control system can detect the technological parameters of cotton forming in real time, a screw guide rail pair motion mechanism is selected as a forming density adjusting mechanism, and the schematic diagram of the forming structure is shown in fig. 6. In addition, in order to prevent seed cotton from falling off during cotton mold forming, a belt and steel roller combination mode is adopted, the cotton bale is formed by compression force between a forming belt 9 and the seed cotton in the forming process, when the maximum volume is reached, in order to form a uniform cylindrical body for the cotton bale, the cotton bale is compacted for the second time by using pressure between the forming belt 9 and the steel roller, the forming belt 9 is tensioned by a tensioning roller 17, meanwhile, the forming belt 9 is tightly attached to the outer sides of ten uniformly distributed forming rollers 18, and in the initial forming state, a lead screw upper slide block drives a compactness adjusting roller 19 to be positioned at a limit position 20 to tension the belt; in the forming process, the compactness adjusting roller 19 is driven by the lead screw slide block 21 to vertically move downwards, pressure sensors distributed at the rear part of the forming bin detect the forming pressure of the cotton mold, and an infrared distance measuring sensor is distributed above the sliding roller and used for detecting the forming diameter of the cotton bale; when the slide block moves to the lowest part, the diameter of the cotton bale reaches the maximum, the forming belt 9 is tightly attached to the inner sides of the ten forming wheel rollers 18, the pressure sensor detects that the pressure reaches the maximum, the forming is finished, and the forming process schematic diagram is shown in fig. 6-8.

The net feeding and cutting part requires a structure which can quickly realize the actions of feeding and cutting, can ensure the smooth transportation of the cotton net 7 after the cotton mould is formed, the mechanism motion is stable and reliable, and can not generate larger vibration to interfere the forming process of the cotton mould, according to the analysis, a net feeding device 13 is designed as shown in figures 6-8, the cotton net 7 enters between a net feeding shaft I4 and a net feeding shaft II 5 through a net guide wheel roller I2 and a net guide wheel roller II 3, the cotton net 7 is transported to a cotton transporting belt 33 through the friction force between the net feeding wheel rollers 1, the cotton transporting belt 33 transports the cotton net 7 to the forming bin body, wherein the net feeding shaft I4 and the net feeding shaft II 5 are meshed through gears, and a net feeding dragging chain wheel 6 is dragged by a motor to transmit power.

Because the cam has inertia impact effect, the pushing force is large, the return speed is fast, therefore, the net cutting device 14 is designed according to the cam mechanism, the net cutting device 14 is as shown in figure 2, because the cam mechanism chooses the motor-sprocket transmission to transmit power in order to reduce the rigid impact of the cam mechanism and realize the adjustable requirement of the net cutting speed, in order to not change the profile curve of the driven sprocket, the rotation center of the cam is fixed on the net cutting driven sprocket 23, therefore the pull rod 24, the net cutting driven sprocket 23 and the left frame of the forming device form a cam mechanism. The working process of the net cutting device 14 is as follows: the net cutting driving chain wheel 22 is dragged to rotate by the motor, the net cutting driven chain wheel 23 is hung on the pull rod mechanism, and the rotating center of the net cutting driving chain wheel 22 and the rotating center shaft I27 of the net cutting driven chain wheel 23 are fixed on the side wall of the rack, so that the rotating center of the net cutting driving chain wheel is kept unchanged during movement; when the net cutting driven chain wheel 23 rotates, the second rotary central shaft 28 of the pull rod 24 moves around the rotary shaft 29, the left horizontal extreme and the right horizontal extreme on the net cutting driven chain wheel 23 are tool withdrawal and net cutting extreme positions, the fixed tool 26 is fixed on the frame, the pull rod 24 on the net cutting driven chain wheel 23 drives the tool rest to horizontally reciprocate, and at the moment, the movable tool 25 and the fixed tool 26 complete net cutting through shearing.
