A screening device for feather processing

Abstract

This invention provides a screening device for feather processing. A vibrating disc moves feathers onto a conveyor, which then carries them through a first detection component to a feeding trough on a feeding plate. The first detection component determines the thickness of the feathers and transmits this information to a signal receiving component. A clamping component then clamps the feathers. A turntable rotates, which in turn rotates the clamping component, causing the feathers to rotate and pass through a second detection component. The second detection component determines the length of the feathers and transmits this information to the signal receiving component. The signal receiving component analyzes the received information and transmits the analysis result back to the clamping component, causing the clamping component to release the feathers, allowing them to fall into corresponding receiving chutes for sorting. This invention solves the problem in existing feather sorting equipment where some feathers are incorrectly sorted, requiring manual re-sorting and severely impacting work efficiency.

Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of feather processing technology, and more particularly to a screening device for feather processing. Background Technology

[0002] In the field of competitive sports, badminton is a widely popular mass sport. A badminton shuttlecock is essential equipment for this sport. It is made from a shuttlecock head, 12 to 16 feathers, string, and adhesive. The manufacturing process generally involves more than ten major steps, including feather selection, inserting the shuttlecock and applying adhesive, stringing, rolling the adhesive, and testing. Manual operations related to the feathers account for more than 50% of the overall shuttlecock manufacturing process. In the feather selection stage, since feathers are taken from poultry and are naturally occurring, each feather inevitably has different lengths and thicknesses. If feathers of different lengths and thicknesses are not sorted according to their size and thickness and are mixed together to make a shuttlecock, the shuttlecock will be unstable during play and unusable. Therefore, it is essential to sort the feathers according to their length and thickness during shuttlecock manufacturing.

[0003] Existing feather sorting equipment primarily uses camera photography as the sorting method. However, this method has a large margin of error and a high probability of incorrect sorting, requiring manual sorting afterwards. This is not only very time-consuming and labor-intensive, but also extremely inefficient. Summary of the Invention

[0050] Please see Figures 1 to 6 As shown, a screening device for feather processing includes:

[0051] A vibratory feeder 1 has a conveyor 2 mounted on one side, and one end of the conveyor 2 is connected to the discharge port of the vibratory feeder 1.

[0052] A feeding plate 3 is disposed at one end of the conveyor 2 away from the vibrating plate 1. A feeding trough 4 is provided on the top of the feeding plate 3, and one end of the feeding trough 4 is connected to one end of the conveyor 2. The other end of the feeding trough 4 passes through the feeding plate 3 and is connected to the outside.

[0053] The first detection component 5 is mounted on top of the feed plate 3, and the first detection component 5 is used to detect the thickness of the feathers;

[0054] A turntable 6 is disposed on the side of the feed plate 3 away from the conveyor 2, and the top of the turntable 6 is provided with a plurality of evenly arranged clamping components 7, each of the clamping components 7 being used to clamp the feathers fed out from the feed trough 4.

[0055] Turntable 8 is mounted on the bottom of turntable 6, and the output shaft of turntable 8 is rotatably connected to turntable 6;

[0056] The second detection component 9 is disposed on the side of the conveyor 2. The working end of the second detection component 9 is located at the outer circle of the turntable 6, and the second detection component 9 is used to detect the length of the feather on the clamping component 7.

[0057] The signal receiving component 10 is mounted on the top of the turntable 6, and the signal receiving component 10 is used to receive the information transmitted by the first detection component 5 and the second detection component 9, and transmit it to the clamping component 7 to release the feather;

[0058] A plurality of receiving slides 11 are provided in a one-to-one correspondence with all the clamping components 7. Each receiving slide 11 is fixed to the bottom of the turntable 6 and each receiving slide 11 is located close to the outer circle of the turntable 6.

[0059] Feathers are moved to conveyor 2 by vibrating plate 1, and then conveyed by conveyor 2 through first detection component 5 to feed trough 4 on feed plate 3. First detection component 5 determines the thickness of the feathers and transmits the detection information to signal receiving component 10. Feathers are clamped by clamping component 7, and turntable 8 drives turntable 6 to rotate. Turntable 6 drives clamping component 7 to rotate, and clamping component 7 drives the feathers to rotate and pass through second detection component 9. Second detection component 9 determines the length of the feathers and transmits the detection information to signal receiving component 10. Signal receiving component 10 analyzes the received information and transmits the analysis result to clamping component 7, causing clamping component 7 to release the feathers and let them fall into the corresponding receiving chute 11 for classification. This solves the problem of existing feather sorting equipment where some feathers are screened incorrectly, requiring manual re-screening, which seriously affects work efficiency. It realizes the problem of multiple screening analysis and rapid classification of feathers.

[0060] As an optional embodiment, a feeding box 12 is provided on the side of the vibratory plate 1 away from the conveyor 2, and a vibrator 13 is mounted on the bottom of the feeding box 12, and the top of the vibrator 13 is fixedly connected to the bottom of the feeding box 12.

[0061] By piling feathers into the feeding box 12 and vibrating the feeding box 12 with the vibrator 13, the feathers automatically fall into the vibrating plate 1, which solves the problem of frequent manual addition of feathers, which is very time-consuming and labor-intensive, and realizes the automatic addition of feathers to the vibrating plate 1.

[0062] As an optional embodiment, the conveyor 2 is provided with a leak-proof plate 14 on each side, and a pressure block 15 is provided on the top of the leak-proof plate 14, and the pressure block 15 is located at the end of the conveyor 2 near the discharge port of the vibrating plate 1.

[0063] By installing a leak-proof plate 14 on the conveyor 2, the feathers will not fall to the sides. By installing a pressure block 15, the feathers will not float upwards due to the feathers being lifted when they fall onto the conveyor 2 through the discharge port of the vibrating plate 1. This solves the problem of feathers falling on the conveyor 2 and achieves the problem of feather protection.

[0064] As an optional embodiment, a correction plate 16 is hinged to the side of the feed plate 3, and a connecting block 17 is provided on the side of the correction plate 16 away from the feed plate 3. A first spring 18 is hinged to the bottom of the connecting block 17, and the end of the first spring 18 away from the connecting block 17 is fixed to the bottom of the feed plate 3.

[0065] By installing a correction plate 16 on the feed plate 3, the feathers are accurately dropped into the clamping assembly 7 from the feed groove 4. The clamping assembly 7 drives the feathers to rotate, and the feathers move by contacting the correction plate 16. The correction plate 16 flips and the connecting block 17 squeezes the first spring 18, causing the feathers to detach from the feed groove 4. The first spring 18 rebounds and moves by contacting the connecting block 17. The connecting block 17 supports the correction plate 16 to reset, allowing the correction plate 16 to continue correcting subsequent feathers. This solves the problem of feathers shifting during entry into the clamping assembly 7 from the feed groove 4, causing the feathers to tilt on the clamping assembly 7 and affecting subsequent inspections. This achieves the problem of feather alignment.

[0066] As an optional embodiment, the first detection component 5 includes:

[0067] A fixing rod 19 is mounted on the feed plate 3 near the conveyor 2, and the fixing rod 19 is located on top of the feed trough 4;

[0068] A pressure tube 20 is sleeved on the fixing rod 19, and the inner diameter of the pressure tube 20 is larger than the diameter of the fixing rod 19;

[0069] The first mounting plate 21 is disposed on the top of the pressure tube 20, and one end of the first mounting plate 21 is fixedly connected to the side of the feed plate 3.

[0070] A force sensor 22 is mounted on the first mounting plate 21, and the detection end of the force sensor 22 is in contact with the pressure tube 20.

[0071] Feathers pass through the pressure tube 20, causing the pressure tube 20 to move upwards. The pressure tube 20 then contacts the force sensor 22. The force sensor 22 determines the thickness of the feather based on the magnitude of the pressure applied and transmits the detection information to the signal receiving component 10. This process completes the classification of feather thickness, solving the problem that the camera cannot determine the thickness of the feathers and enabling the determination of feather thickness.

[0072] As an optional embodiment, the clamping assembly 7 includes:

[0073] The second mounting plate 23 has a clamping base plate 24 on the side near the feed plate 3, and the clamping base plate 24 is fixedly connected to the turntable 6.

[0074] A dual-shaft cylinder 25 is mounted on the second mounting plate 23;

[0075] The notched pressure head 26 is disposed on the top of the clamping base plate 24, and the notched pressure head 26 is fixedly connected to the output shaft of the dual-shaft cylinder 25.

[0076] The dual-axis cylinder 25 drives the notched pressure head 26 to move downward and close with the clamping base plate 24 to clamp the feathers, so that the feathers will not fall off during rotation. This solves the problem of clamping feathers during the sorting process and realizes the problem of clamping and rotating feathers.

[0077] As an optional embodiment, a buffer assembly is provided between the notch pressure head 26 and the dual-axis cylinder 25, the buffer assembly comprising:

[0078] The third mounting plate 27 is disposed on the output shaft of the dual-shaft cylinder 25;

[0079] Two second springs 28 are disposed between the third mounting plate 27 and the notched pressure head 26, and the two ends of each second spring 28 abut against the bottom of the third mounting plate 27 and the top of the notched pressure head 26, respectively.

[0080] Two limiting rods 29 are respectively disposed inside a second spring 28, and one end of each limiting rod 29 is fixedly connected to the notch pressure head 26, and the other end of each limiting rod 29 passes through the third mounting plate 27.

[0081] The third mounting plate 27 is moved downward by the dual-axis cylinder 25, which in turn moves the spring downward. The spring then moves the notched pressure head 26 downward, thus clamping the feathers. The spring's elasticity prevents the notched pressure head 26 from crushing the feathers and flattening the feather bones. By installing a limiting rod 29 in the spring, the spring is prevented from detaching from the third mounting plate 27 and the notched pressure head 26. This solves the problem of the notched pressure head 26 flattening the feather bones when it is in contact with the clamping base plate 24, and enables the notched pressure head 26 to have a buffering function.

[0082] As an optional embodiment, the second detection component 9 includes:

[0083] The fourth mounting plate 30 has a C-shaped frame 31 obliquely provided on its top, and the open end of the C-shaped frame 31 is located close to the clamping base plate 24;

[0084] Several sensor heads 32 are symmetrically and evenly distributed on the upper and lower side walls inside the C-shaped frame 31;

[0085] The feather passes through the C-shaped frame 31, and the length of the feather is determined based on the number of feathers illuminated by the sensor head 32.

[0086] For example, when a feather passes through the C-shaped frame 31, it blocks the mutual illumination between the sensor heads 32. The length of the feather is determined based on the number of feathers blocking the sensor heads 32, and the detection information is transmitted to the signal receiving component 10. This allows the feather to complete the length classification process, solving the problem of errors in the camera's detection of feather length and achieving accurate judgment of feather length.

[0087] As an optional embodiment, the signal receiving component 10 includes:

[0088] A fixed column 33 is disposed at the center of the turntable 8, and one end of the fixed column 33 passes through the turntable 6;

[0089] Mounting plate 34 is disposed on the top of the fixing post 33, and the outer circle of the mounting plate 34 is provided with a plurality of extension plates 35 corresponding to all the second mounting plates 23.

[0090] Several first sensors 36 are respectively mounted on the top of a second mounting plate 23;

[0091] Several second sensors 37 are respectively mounted on an extension plate 35, and each second sensor 37 is corresponding to a first sensor 36.

[0092] For example, when a feather is inserted into the corresponding notch and clamped by the pressure head 26, the corresponding first sensor 36 indicator light is activated. The detection information is transmitted to the second sensor 37 for analysis via the force sensor 22 and the sensing head 32. The analysis activates the corresponding second sensor 37 indicator light. The turntable 6 rotates until the first sensor 36 and the corresponding second sensor 37 with their indicator lights activated sense each other. The first sensor 36 controls the dual-axis cylinder 25 to reset, causing the feather to fall into the corresponding receiving chute 11 for sorting. This solves the problem of how to sort feathers according to their thickness and length, and enables rapid sorting of feathers.
