[0026] To make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0027] It should be mentioned that the front detection camera 21 and the rear detection camera 31 in the embodiments of the present application are both linked by a processing controller and are used to control the corresponding air blowing nozzles 33 to start and complete the sorting of feathers. The proximity switch 24 is used to match with the front conveyor belt 22, so as to adjust the travel of the front conveyor belt 22 when the front spaced groove 222 and the rear spaced groove 322 do not achieve effective corresponding pairing, and improve the conveying accuracy of the feathers. This will not be elaborated here.

[0028] As Figure 1As shown in the figure, a high-speed feather sorting machine includes a feeding unit 1, a front detection unit 2, and a back detection unit 3. Among them, the feeding unit 1 is used to convey feathers into the front detection unit 2. The front detection unit 2 is provided with a front detection camera 21 for detecting the front morphological specifications of feathers and a flipping unit for flipping and conveying the feathers into the back detection unit 3. The back detection unit 3 is provided with a back detection camera 31 for detecting the back morphological specifications of feathers, a plurality of discharging units for matching feathers at corresponding positions, and a receiving box 35 for matching the discharging units. Therefore, after the feeding unit 1 automatically conveys the feathers into the front detection unit 2, the front detection unit 2 drives the feathers to move forward, and the front detection camera 21 detects the front morphological specifications of the feathers. Then, the flipping unit conveys the feathers in the process of movement into the back detection unit 3 for continuous movement, and the back detection camera 31 detects the back morphological specifications of the feathers during the movement. Thus, by combining the morphological specifications of the front and back, the corresponding feathers are sorted into the matching receiving box 35 through the discharging units, completing the rapid and high-precision sorting of feathers, and optimizing the structural composition of the high-speed feather sorting machine, thereby significantly reducing the production and manufacturing costs and the maintenance and repair costs.

[0029] In order to achieve the orderly installation of the feeding unit 1, the front detection unit 2, and the back detection unit 3, the high-speed feather sorting machine further includes a frame 4. Then, the feeding unit 1, the front detection unit 2, and the back detection unit 3 are installed and fixed on the frame 4. The movement of the whole equipment can be completed through the moving wheels of the frame 4. A storage chamber (not shown in the figure) is provided on the frame 4 to achieve the effect of storing parts, thereby significantly improving the practicability of the high-speed feather sorting machine.

[0030] As Figure 1 、 Figure 2As shown, the front detection unit 2 includes a front conveyor belt 22. The front conveyor belt 22 is provided with a plurality of front spacing ribs 221 distributed at equal intervals, and a front spacing groove 222 matching the feather is formed between two adjacent front spacing ribs 221. The flip unit includes a flip plate 25 located at one end of the front conveyor belt 22, and the flip plate 25 is used to match the front spacing groove 222 and limit the flipping movement of the feather relative to the front conveyor belt 22. At the same time, the back detection unit 3 is located at the lower side of the front detection unit 2 and is used to receive the feather introduced through the flip plate 25. Therefore, the front conveyor belt 22 is used to operate continuously and drive the feathers to move forward, and the front spacing grooves 222 between two adjacent front spacing ribs 221 effectively limit the feathers to prevent the feathers from escaping from the corresponding front spacing grooves 222. When the feather moves to one end of the flip sleeve 25, the flip sleeve 25 limits the feathers from escaping from the corresponding front spacing grooves 222, and in the process of the feathers moving from the upper side to the lower side of the front conveyor belt 22, the flip sleeve 25 supports the feathers to cooperate with the front spacing ribs 221 on the front conveyor belt 22 to push the feathers forward. At this time, the feathers will be gradually pushed to the back detection unit 3 located on the lower side of the front detection unit 2 as the front spacing ribs 221 move, and as the back detection unit 3 runs, the feathers will be driven to further move and detect and sort the back shape specifications. It should be mentioned that, if Figure 3 , Figure 4 As shown, an upwardly inclined feeding guide 251 is provided on the upper side of the flip plate 25, and a downwardly inclined discharging feeding section 252 is provided on the lower side of the flip plate 25. The feeding guide 251 effectively guides the feathers to enter the inner side of the flip plate 25 along with the front conveyor belt 22, so as to avoid the feathers from being offset and affecting the transmission and detection of the feathers; the discharging feeding section 252 is used to effectively guide the feathers into the back detection unit 3, so as to prevent the front spacing ribs 221 from continuing to push the feathers to move and affecting the automatic feeding effect of the feathers and the back detection unit 3.

[0031] In order to improve the feeding stability of feathers, a feeding limit cover plate 23 is provided on the upper side of the discharging and feeding part 252. The feeding unit 1 is composed of a plurality of feeding pipes matching the corresponding front spacing grooves 222 and a partition cavity 11 for guiding the feathers in the feeding pipes into the corresponding front spacing grooves 222, and the partition cavity 11 is connected to the feeding limit cover plate 23. Therefore, the feeding limit plate plays a role in preventing the position of the feathers entering the front spacing grooves 222 through the partition cavity 11 from being offset, thereby significantly improving the accuracy and stability of the automatic feeding of feathers, thereby achieving the improvement of the detection accuracy and efficiency of the front and back morphological specifications of the feathers.

[0032] like Figure 3 , Figure 4 , Figure 5As shown in the figure, the back detection unit 3 includes a back conveyor belt 32. The back conveyor belt 32 is provided with a plurality of equally spaced back spacer ribs 321, and a back spacer groove 322 matching the feathers is formed between two adjacent back spacer ribs 321. The back spacer groove 322 is used to match and correspond to the front spacer groove 222 up and down. At the same time, the discharging unit includes a plurality of blowing nozzles 33 matching the corresponding back spacer grooves 322, and each blowing nozzle 33 is correspondingly provided with a guiding cylinder 34 for guiding the movement of the feathers. The guiding cylinder 34 matches the corresponding receiving box 35. Therefore, the back conveyor belt 32 is used to continuously run and drive the feathers to move forward, and the back spacer grooves 322 between two adjacent back spacer ribs 321 effectively limit the feathers to prevent the feathers from detaching from the corresponding back spacer grooves 322. Then, when the feathers move to match the corresponding blowing nozzles 33, the corresponding feathers are blown into the guiding cylinder 34 through the blowing nozzles 33, and the feathers are introduced into the corresponding receiving box 35 through the guiding cylinder 34 to complete the sorting of the feathers.

[0033] It should be mentioned that the plurality of blowing nozzles 33 are arranged in two rows and are spaced apart on both sides of the back conveyor belt 32 respectively. Then, after the feathers are arranged at intervals and distributed on both sides, the problem that the distance between two adjacent blowing nozzles 33 is too small and affects the sorting accuracy of the feathers will be effectively prevented, and the sorting efficiency of the feathers will be significantly improved.

[0034] In order to realize the orderly operation of the front conveyor belt 22 and the back conveyor belt 32, a motor is used to drive the front conveyor belt 22 or the back conveyor belt 32 to run, and the driving operation is realized by setting a meshing gear set between the front conveyor belt 22 and the back conveyor belt 32 for transmission, or a corresponding motor is set on both the front conveyor belt 22 and the back conveyor belt 32 for driving operation.

[0035] In the embodiment of the present application, the front conveyor belt 22 and the back conveyor belt 32 are both driven by corresponding motors to run, and the rotation directions of the front conveyor belt 22 and the back conveyor belt 32 are opposite, so as to realize the matching and corresponding movement of the back spacer groove 322 and the front spacer groove 222. At the same time, a proximity switch 24 is provided on the front conveyor belt 22 or the back conveyor belt 32. The proximity switch 24 is used to monitor the positions of the corresponding front spacer ribs 221 or back spacer ribs 321, and drive the corresponding motor to control the matching and correspondence of the back spacer groove 322 and the front spacer groove 222. Therefore, during the process of the motor driving the front conveyor belt 22 and the back conveyor belt 32 to run, it cooperates with the proximity switch 24 to realize the matching and correspondence of the back spacer groove 322 and the front spacer groove 222, so as to improve the accuracy and efficiency of the feathers during flipping and transferring.

[0036] In summary, the present invention discloses a high-speed feather slicing machine. The high-speed feather slicing machine flips and conveys the feathers that have passed the front morphology specification detection into the back detection unit 3 through the flipping unit, so that after the back detection camera 31 of the back detection unit detects the back morphology specification of the feathers, the feathers enter the corresponding receiving box 35 through the discharging unit, and the sorting of the feathers can be completed. The feathers are kept moving continuously during the process of traveling and being detected, so as to achieve the purpose of fully automatic feeding, detection and sorting, significantly improving the sorting accuracy and efficiency of the feathers. Moreover, the overall structure of the high-speed feather slicing machine is simple, thus significantly reducing the production cost and the maintenance cost.
