Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0027] Embodiment 1

[0028] As shown in Figure 1 and 2 , a feather product raw material pretreatment system includes a feather conveying mechanism, the feather conveying mechanism is sequentially provided with a soaking cleaning chamber 1, a spray cleaning chamber 2 and a drying chamber 3 along the conveying direction of the feather, the feather conveying mechanism includes a rack 4, the rack 4 is provided with a ring-shaped transmission chain 5, the rack 4 is installed with a motor-driven transmission roller and a driven roller cooperating with the transmission roller, the transmission chain 5 is sleeved on the outside of the transmission roller and the driven roller and is driven by the motor.

[0029] As shown in Figure 1 and 3As shown in Figure 6, inverted L-shaped locking blocks 6 are evenly distributed circumferentially on the outer side of the transmission chain 5. Feather positioning components 7 are engaged at the inverted L-shaped locking blocks 6. The feather positioning components 7 include a positioning plate 8. Multiple vertical positioning grooves 9 are spaced apart at the upper end of the positioning plate 8. A transverse clamping groove 10 is provided inside the positioning plate 8. The transverse clamping groove 10 extends transversely through the middle of all positioning grooves 9. Multiple spacer strips 11 are superimposed and filled inside the transverse clamping groove 10. The spacer strips 11 can be elastic strips such as rubber strips. A feather clamping seam 12 is formed between two adjacent spacer strips 11 inside the positioning groove 9. The end of the feather shank is inserted into the feather clamping seam 12 to position the feather to be cleaned.

[0030] like Figure 5 and 6 As shown, one end of the transverse clamping groove 10 is closed, and the other end is open. A pressing assembly for fixing the spacer strip 11 is provided at the open end. The pressing assembly includes a pressing rod 13, which is placed inside the transverse clamping groove 10 through the open end. The pressing rod 13 is detachably connected to the positioning plate 8. For example, the ends of the pressing rod 13 and the positioning plate 8 can be connected by a binding strap 14. The end of the binding strap 14 can be Velcro, snap-fit, etc. A connecting groove is provided between the pressing rod 13 and the positioning plate 8 at the corresponding position of the binding strap 14. The binding strap is placed in the connecting groove to prevent it from sliding or falling off. Alternatively, both ends of the positioning plate 8 are fixed with pull rods 15. The end of the pressing rod 13 has a connecting hole through which the pull rod 15 passes and is screwed with a locking nut. With the pressing assembly, when feathers are inserted into the feather clamping slot 12, the pressing rod 13 is installed to press and fix the spacer strip 11, thereby pressing and fixing the feathers and preventing them from falling off during the feather transport process. The positioning plate 8 is also provided with multiple water-permeable holes 16 to facilitate the outflow of water that enters the positioning groove 9 or the transverse clamping groove 10.

[0031] like Figure 3 and 4 As shown, the lower end of the feather positioning assembly 7 is provided with an inverted L-shaped groove 17 that mates with the inverted L-shaped locking block 6. The inverted L-shaped groove 17 is arranged perpendicular to the movement direction of the transmission chain 5. One end of the inverted L-shaped groove 17 is an open end, and the other end is a closed end, and a limit baffle 18 is fixed thereon. The limit baffle 18 is located on the rear side of the inverted L-shaped groove 17. When the inverted L-shaped locking block 6 is placed at the closed end of the inverted L-shaped groove 17, the limit baffle 18 is used to prevent the inverted L-shaped locking block 6 from falling out of the inverted L-shaped groove 17. Edge baffles 19 are fixed on both sides of the frame 4 of the transmission chain 5. The edge baffles 19 limit the conveying trajectory of the feather positioning assembly 7 to prevent the feather positioning assembly 7 from swaying back and forth during movement and falling off the inverted L-shaped locking block 6.

[0032] like Figure 1 and 2As shown, the rack 4 at the feeding port of the soaking cleaning chamber 1 is provided with a feeding station, and the feeding station is provided with a feeding assembly matched with the feather positioning assembly 7. The feeding assembly includes a feeding baffle 20 and a feeding inclined guide plate 21 arranged in sequence along the feather conveying direction. The feeding baffle 20 is fixed to the rack 4 on one side of the feeding station and located inside the limiting baffle 18 on the same side. The feeding inclined guide plate 21 is fixed to the rack 4 on the other side of the feeding station and located outside the limiting baffle 18 on the same side. The feeding inclined guide plate 21 is inclined to the opening end of the inverted L-shaped clamping groove 17. In order to better position and guide the feather positioning assembly 7, a feeding inclined support plate can also be fixed to the discharge end of the feeding baffle 20, and the feeding inclined support plate is parallel to the feeding inclined guide plate 21. At the feeding station, the feather positioning assembly 7 abuts against the feeding baffle 20. The transmission chain 5 drives the inverted L-shaped clamping block 6 to move to the opening end of the inverted L-shaped clamping groove 17, and the inverted L-shaped clamping block 6 is placed in the inverted L-shaped clamping groove 17 and pushes the feather positioning assembly 7 to move synchronously. The feather positioning assembly 7 is separated from the feeding baffle 20 and moves to the feeding inclined guide plate 21. With the movement of the feather positioning assembly 7 along the feeding inclined guide plate 21, the inverted L-shaped clamping block 6 is placed in the closed end of the inverted L-shaped clamping groove 17, i.e. in the inverted L-shaped clamping groove 17 at the limiting baffle 18. Through the arrangement of the structure, the feather positioning assembly 7 is not easy to fall off when it is conveyed downward with the transmission chain 5.

[0033] The rack 4 at the discharge port of the drying chamber 3 is provided with a discharging station, and the discharging station is fixed with a discharging inclined guide plate 22. The discharging inclined guide plate 22 is inclined to the side close to the limiting baffle 18 (i.e. inclined to the closed end of the inverted L-shaped clamping groove 17). The feather positioning assembly 7 moves to the discharging inclined guide plate 22 with the transmission chain 5. With the movement of the feather positioning assembly 7 along the discharging inclined guide plate 22, the inverted L-shaped clamping groove 17 is away from the inverted L-shaped clamping block 6, i.e. the feather positioning assembly 7 is separated from the transmission chain 5. The outlet end of the discharging inclined guide plate 22 is provided with a discharging conveying belt 23. The feather positioning assembly 7 is separated from the transmission chain 5 and enters the discharging conveying belt 23. The automatic discharging of the feather positioning assembly 7 is realized through the discharging conveying belt 23.

[0034] The use method of the feather product raw material pretreatment system includes the following steps:

[0035] (1) vertically insert the feather handle into the feather clamping slot 12. When the feather positioning assembly 7 is full of the feathers to be cleaned and is clamped and fixed by the extrusion assembly, the feather positioning assembly 7 is placed at the feeding station and abuts against the feeding baffle 20. The transmission chain 5 drives the inverted L-shaped clamping block 6 to be placed at the opening end of the inverted L-shaped clamping groove 17 and pushes the feather positioning assembly 7 to move synchronously.

[0036] (2) the transmission chain 5 drives the feather positioning assembly 7 to move along the feeding inclined guide plate 21, so that the inverted L-shaped clamping block 6 is placed at the limiting baffle 18 of the inverted L-shaped clamping groove 17.

[0037] (3) The driving chain 5 drives the feather positioning assembly 7 to enter the soaking cleaning chamber 1 for primary cleaning, the spray cleaning chamber 2 for secondary cleaning, and finally the drying chamber 3 for drying.

[0038] (4) After the feather positioning assembly 7 comes out of the drying chamber 3, it enters the discharging station, and the driving chain 5 drives the feather positioning assembly 7 to move along the discharging inclined guide plate 22, so that the inverted L-shaped clamping block 6 is separated from the inverted L-shaped clamping groove 17 and enters the discharging conveyor belt 23 for discharging.

[0039] Example 2

[0040] This example is basically the same as example 1, except that, as shown in Figure 1 , the top of the soaking cleaning chamber 1 is fixed with a spray pipeline 24, and the lower side of the soaking cleaning chamber 1 is provided with a soaking pool 25, which contains cleaning liquid. A heater can be provided in the soaking pool 25 as needed to heat the cleaning liquid, improving the efficiency of soaking cleaning. The driving chain 5 has a trapezoidal ring structure, and the driving chain 5 is U-shapedly conveyed in the soaking cleaning chamber 1 and returns through the soaking pool 25. Specifically, the driving chain 5 drives the feather positioning assembly 7 to move horizontally at the upper side of the soaking cleaning chamber 1 first, sprays the feathers through the spray pipeline 24, and cooperates with the rising hot steam to pre-soak the dirt on the feathers, reducing the adhesion of the dirt, and facilitating subsequent cleaning. Then the driving chain 5 drives the feather positioning assembly 7 to be adjusted downward, and returns horizontally at the lower side of the soaking cleaning chamber 1, i.e. returns through the soaking pool 25.

[0041] As shown in Figure 1 , 7 and 8, the front and rear sides of the upper end of the soaking pool 25 are provided with overflow grooves 26, and the bottom of the soaking pool 25 is fixed with an aeration pipeline 27 and a water flushing pipeline 28. The aeration pipeline 27 is connected with an aeration pump, and the spray pipeline 24 and the water flushing pipeline 28 are connected with a circulating pump. The circulating pump is connected with the overflow grooves 26 through a filter 29. The specific structure is that the end of the soaking pool 25 away from the spray cleaning chamber 2 is fixed with a filter chamber 35, the two sides of the filter chamber 35 are fixed with vertical partitions 36, the filter 29 is fixed between the two partitions 36, the lower side of the filter 29 is a sediment tank 37, and the upper side of the filter 29 is a clear liquid tank 38. One end of the circulating pump is connected with the clear liquid tank 38, and the other end is connected with the spray pipeline 24 and the water flushing pipeline 28 respectively. The side of the partition 36 away from the filter 29 is an overflow water outlet groove 39, which is communicated with the sediment tank 37 through the lower end of the partition 36, i.e. the lower end of the partition 36 is spaced apart from the bottom of the filter chamber 35. The bottom of the overflow groove 26 is inclined downward, the lower end of the overflow groove 26 is communicated with the overflow water outlet groove 39, and the bottom of the sediment tank 37 is provided with a sewage valve (not shown in the figure) for discharging sewage from the sediment tank 37.

[0042] When the driving chain 5 drives the feather positioning assembly 7 to enter the soaking pool 25 for cleaning, the feather positioning assembly 7 is subjected to air flushing through the air flushing pipeline 27 and water flushing through the water flushing pipeline 28. Through the cooperation of air flushing and water flushing, the disturbance of the cleaning liquid is increased, the cleaning effect of the feather is improved, and the dirt after cleaning is suspended on the surface of the soaking pool 25 and enters the overflow groove 26, and then is filtered through the filter 29 and recycled by the circulating pump. The dirty water after cleaning enters the sedimentation tank 37 through the overflow groove 26 and the overflow water outlet groove 39 in turn, is filtered through the filter 29 and enters the clear liquid tank 38, and finally is recycled by the circulating pump. The water flushing pipeline 28 is also connected with the water inlet pipeline, so as to facilitate the supplement of the cleaning liquid in the soaking pool 25.

[0043] As shown in Figure 1 The soaking cleaning chamber 1 is provided with a direction adjusting roller 30 at a position close to the outlet. The driving chain 5 is inclined upward and away from the soaking pool 25 through the direction adjusting roller 30. The inside of the outlet of the soaking cleaning chamber 1 is provided with a first vibrator 31. The feather positioning assembly 7 is vibrated through the first vibrator 31. After the feather positioning assembly 7 is driven by the driving chain 5 to leave the soaking pool 25, the feather positioning assembly 7 is vibrated through the first vibrator 31, so that the water droplets attached to the feather fall off.

[0044] The upper side and the front and rear sides of the spraying cleaning chamber 2 are fixedly provided with spraying cleaning pipes 32. The lower side of the spraying cleaning chamber 2 is provided with a water collecting groove 33. The feather is subjected to secondary cleaning through the spraying cleaning pipes 32. The inside of the outlet of the spraying cleaning chamber 2 is provided with a second vibrator 34. The feather positioning assembly 7 is vibrated through the second vibrator 34, so that the water droplets attached to the feather fall off. The driving chain 5 drives the feather positioning assembly 7 to leave the soaking cleaning chamber 1, passes through the spraying cleaning chamber 2, and finally enters the drying chamber 3. The driving chain 5 adopts a U-shaped return in the drying chamber 3. The feeding port of the soaking cleaning chamber 1 and the discharging port of the drying chamber 3 are oppositely arranged.

[0045] The above only describes the preferred embodiments of the present application and is not used to limit the present application.
