Description

Technical Field

[0001] The invention relates to the technical field of poultry meat product processing, in particular to a skin depilatory device for poultry meat product processing. Background Art

[0002] In the production and processing of agricultural and sideline products, to ensure the cleanliness and hygiene of poultry products and their compliance with food safety standards, it is often necessary to remove feathers from the surface of slaughtered poultry using a depilatory machine. This process is a key step in poultry processing, not only improving production efficiency but also ensuring the product's appearance quality and sanitation, paving the way for subsequent cutting, cleaning, and packaging processes, thereby enhancing the market competitiveness and added value of agricultural and sideline products.

[0003] When traditional poultry plucking machines are used, feathers typically leak through the gap between the rotating turntable and the barrel wall to the lower wall before being discharged. When processing multiple birds at once, a large amount of feathers is quickly generated and discharged through the gap between the turntable and the barrel wall. Excessive feathers or tangled feathers can easily clog the discharge port, preventing smooth discharge. This requires cleaning the barrel wall after each plucking, reducing overall efficiency. Summary of the Invention

[0004] In order to overcome the shortcoming that feathers on the tube wall are difficult to be effectively cleaned, the present invention provides a skin depilatory device for processing poultry meat products.

[0005] A skin depilatory device for processing poultry meat products includes a fixed base, the fixed base is provided with a drain outlet, a material guide slope is arranged in the fixed base, the fixed base is fixedly connected to a fixed retaining ring, a movable retaining ring is slidably connected between the fixed base and the fixed retaining ring, the movable retaining ring is used to block the drain outlet of the fixed base, a first spring symmetrically distributed along the movable retaining ring is fixedly connected between the fixed base and the movable retaining ring, the fixed base is fixedly connected to a motor, the fixed base is rotatably connected to a rotating rack, the rotating rack is threadedly connected to the movable retaining ring, a plurality of rubber columns are fixedly connected to the inner wall of the fixed retaining ring and the top of the rotating rack, an annular water pipe is fixedly connected to the top of the fixed retaining ring, the annular water pipe is connected to a folding nozzle distributed along the circumference, and an angle adjustment component.

[0006] Furthermore, the angle adjustment assembly includes a first fixed block symmetrically distributed along the folding nozzle, the first fixed block is fixedly connected to the fixed retaining ring, the first fixed block is rotatably connected to a rotating plate, the rotating plate is fixedly connected to the adjacent folding nozzle, a torsion spring is fixed between the folding nozzle and the adjacent first fixed block, the fixed retaining ring is slidably connected to a top frame, and the top frame is in contact with the rotating plate.

[0007] Furthermore, the top frame is fixedly connected to the movable retaining ring.

[0008] Furthermore, it also includes a fixing frame symmetrically distributed along the fixed base, the fixing frame is fixedly connected to the fixed base, the fixing frame is slidably connected to a clamping frame for clamping the movable retaining ring, and the fixing frame and the adjacent clamping frame are fixedly connected to a second spring.

[0009] Furthermore, the end surface of the bracket close to the movable retaining ring is set as a wedge surface, and the movable retaining ring moves downward to contact the wedge surface adjacent to the bracket.

[0010] Furthermore, it also includes a water inlet pipe, which is fixed to the side of the fixed base away from the drain outlet. The movable retaining ring is fixed with a block for blocking the bottom end of the water inlet pipe. The water inlet pipe is connected to the annular water pipe.

[0011] Furthermore, the inner diameter of the annular water pipe is smaller than the inner diameter of the water inlet pipe.

[0012] Furthermore, it also includes a second fixed block, which is fixed to the side of the fixed base close to the drain outlet. The second fixed block is rotatably connected to the guide rod, and the guide rod is slidably connected to the clamping rod. A third spring is fixed between the guide rod and the clamping rod. The second fixed block has at least two clamping holes, and the clamping rod is clamped in one of the clamping holes.

[0013] The beneficial effects are as follows: during depilation, the present invention sprays hot water onto the poultry through the folding nozzle, thereby accelerating the depilation process; during cleaning, the present invention sprays hot water onto the inner wall of the fixed retaining ring through the folding nozzle, so that the feathers on the inner wall of the fixed retaining ring slide down along the water flow into the fixed base, and finally the feathers in the fixed base are discharged out of the drain outlet of the fixed base along the water flow and the material guide slope, thereby achieving the effect of automatically cleaning the feathers inside the device.

[0014] The present invention fixes the movable retaining ring in this position by a clamping frame, thereby preventing the movable retaining ring from easily jumping up and down slightly during the depilation period, causing feathers to be stuck between the gap between the fixed retaining ring and the movable retaining ring. At the same time, the present invention prevents the movable retaining ring from immediately springing upward when the motor is turned off, causing poultry to be discharged together with the feathers and stuck in the drain outlet of the fixed base.

[0015] The present invention utilizes a movable retaining ring to drive a retaining block to synchronously move up and down to control the opening and closing of the pipe opening at the bottom end of the water inlet pipe, so that during the depilation period, except for a small portion of hot water used for depilation, most of the hot water is used to flush feathers remaining in the fixed base, thereby preventing the remaining feathers from being blocked in the fixed base and affecting the subsequent flushing and discharge of the feathers. During the flushing and discharge period, all the hot water is used to flush the feathers that have just fallen off in the fixed retaining ring, thereby increasing the amount of water used to clean the inner wall of the fixed retaining ring.

[0016] During depilation, the present invention fixes the guide rod in the fixed base so that the feathers are blocked and guided by the guide rod during rotation and discharged from the water outlet of the fixed base. During cleaning, the guide rod is rotated out of the fixed base so that the feathers blocked on the left side of the guide rod can also be discharged with the water.

DETAILED DESCRIPTION

[0028] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1: A poultry meat product processing epidermal depilatory device, such as Figure 1-Figure 3 As shown, it includes a fixed base 1, a drainage port is opened on the front side of the fixed base 1, a guide slope 101 is provided in the fixed base 1, a fixed retaining ring 2 is fixedly connected to the upper part of the fixed base 1, a movable retaining ring 3 is connected between the fixed base 1 and the fixed retaining ring 2 along the up and down sliding, the movable retaining ring 3 is used to block the drainage port of the fixed base 1, a first spring 4 symmetrically distributed along the movable retaining ring 3 is fixed between the fixed base 1 and the movable retaining ring 3, a motor 5 is fixedly connected to the lower part of the fixed base 1, a rotating frame 6 is rotatably connected in the fixed base 1, and the rotating frame 6 is connected to the fixed base 1. The frame 6 is threadedly connected to the movable retaining ring 3. A plurality of rubber columns 7 are fixed to the inner wall of the fixed retaining ring 2 and the top of the rotating frame 6. The rubber columns 7 are used to depilate the poultry. An annular water pipe 8 is fixed to the top of the fixed retaining ring 2. The annular water pipe 8 is connected to the folding nozzles 9 distributed along the circumferential direction. When the folding nozzles 9 are turned toward the poultry, hot water is evenly sprayed on the poultry through the folding nozzles 9 for depilation. When the folding nozzles 9 are turned toward the inner wall of the fixed retaining ring 2, hot water is evenly sprayed on the inner wall of the fixed retaining ring 2 through the folding nozzles 9 for cleaning.

[0030] like Figure 4-Figure 6 As shown, it also includes a first fixed block 10 symmetrically distributed along the folding nozzle 9, the first fixed block 10 is fixedly connected to the inner top of the fixed retaining ring 2, the first fixed block 10 is rotatably connected to the rotating plate 11, the rotating plate 11 is fixedly connected to the adjacent folding nozzle 9, and a torsion spring 12 is fixedly connected between the folding nozzle 9 and the adjacent first fixed block 10, the fixed retaining ring 2 is slidably connected to the top frame 13 in the up and down directions, the top of the top frame 13 contacts the rotating plate 11, and the bottom of the top frame 13 is fixedly connected to the movable retaining ring 3, the movable retaining ring 3 moves up and down to drive the top frame 13 to move up and down synchronously, and the top frame 13 moves upward to push the rotating plate 11 to rotate, so that the rotating plate 11 drives the folding nozzle 9 to rotate to the angle toward the inner wall of the fixed retaining ring 2.

[0031] When using this device to depilate poultry, first, start the motor 5, and the output shaft of the motor 5 drives the rotary frame 6 to rotate. When the rotary frame 6 rotates, it drives the movable retaining ring 3 to slide downward, and the first spring 4 is compressed until the movable retaining ring 3 blocks the drain outlet of the fixed base 1. When the movable retaining ring 3 moves downward, it drives the top frame 13 to move downward synchronously, so that the top frame 13 is separated from the rotating plate 11, and the torsion spring 12 in the stored force state is reset to drive the rotating plate 11 to swing downward, thereby driving the folding nozzle 9 to swing to the side away from the inner wall of the fixed retaining ring 2, so that the folding nozzle 9 is directed towards the poultry. Then, the poultry to be depilated is placed in the fixed retaining ring 2, and hot water is introduced into the annular water pipe 8. The hot water is sprinkled on the poultry through the folding nozzle 9, and the rotary frame 6 drives the rubber column 7 thereon to rotate. In this way, the rubber column 7 on the rotary frame 6 cooperates with the rubber column 7 in the fixed retaining ring 2 to depilate the poultry.

[0032] After the feather removal is completed, the motor 5 is turned off and the feathered poultry is taken out. The first spring 4 is reset to drive the movable retaining ring 3 to slide upward, and the drain outlet of the fixed base 1 is opened, so that the fallen feathers slide along the circumference of the rotating frame 6 to the fixed base 1, and then are discharged to the drain outlet of the fixed base 1 along the water flow. When the movable retaining ring 3 moves upward, it drives the top frame 13 to move upward synchronously, so that the top frame 13 first contacts the rotating plate 11, and then pushes the rotating plate 11 to swing upward, the torsion spring 12 deforms and accumulates force, and the rotating plate 11 drives the folding nozzle 9 to swing toward the inner wall of the fixed retaining ring 2. In this way, the hot water sprayed by the folding nozzle 9 is sprayed onto the inner wall of the fixed retaining ring 2, and the feathers on the inner wall of the fixed retaining ring 2 slide down into the fixed base 1 along the water flow, and finally the feathers in the fixed base 1 are discharged out of the drain outlet of the fixed base 1 along the water flow and the guide slope 101, thereby achieving the effect of automatically cleaning the feathers inside the device.

[0033] Example 2: Based on Example 1, Figure 7 As shown, it also includes a fixing frame 14 symmetrically distributed along the fixed base 1. The fixing frame 14 is fixedly connected to the outer wall of the fixed base 1. The fixing frame 14 is slidably connected to the clamping frame 15 in the front and rear directions. The end face of the rear side of the clamping frame 15 is set as a wedge surface. The movable retaining ring 3 moves downward and contacts the wedge surface of the adjacent clamping frame 15. When the movable retaining ring 3 moves downward to the bottom of the adjacent clamping frame 15, the clamping frame 15 clamps the movable retaining ring 3. The fixing frame 14 and the adjacent clamping frame 15 are fixedly connected by a second spring 16.

[0034] After the motor 5 is turned off and the poultry is taken out, the bracket 15 is pulled forward to release the limit of the movable retaining ring 3 by the bracket 15, so that the movable retaining ring 3 can be reset upward with the first spring 4 to open the drain outlet of the fixed base 1.

[0035] Example 3: Based on Example 2, Figure 8 As shown, it also includes a water inlet pipe 17, which is fixed to the rear side of the fixed base 1, and a block 18 is fixed to the movable retaining ring 3. The block 18 blocks the bottom end of the water inlet pipe 17, and the upper part of the water inlet pipe 17 is connected to the annular water pipe 8. The inner diameter of the annular water pipe 8 is smaller than the inner diameter of the water inlet pipe 17.

[0036] When the movable retaining ring 3 moves downward, the movable retaining ring 3 drives the stopper 18 to move downward until it is disengaged from the water inlet pipe 17. At this time, since the static pressure head at the bottom pipe opening of the water inlet pipe 17 is greater than the static pressure head at the side of the water inlet pipe 17 close to the annular water pipe 8, and since the inner diameter of the annular water pipe 8 is smaller than the inner diameter of the water inlet pipe 17, the amount of hot water in the water inlet pipe 17 flowing into the annular water pipe 8 is less than the amount of water flowing into the fixed base 1. In this way, during the depilation period, in addition to a small part of the hot water being used for depilation, most of the hot water is used to flush the feathers remaining in the fixed base 1, so as to prevent the residual feathers from being blocked in the fixed base 1, which would affect the subsequent flushing and discharge of the feathers.

[0037] When the movable retaining ring 3 moves upward, the movable retaining ring 3 drives the stopper 18 to move upward to block the pipe opening at the bottom of the water inlet pipe 17, so that the hot water in the water inlet pipe 17 can only flow into the annular water pipe 8. In this way, during the flushing and feather removal period, all the hot water is used to flush the feathers that have just fallen off in the fixed retaining ring 2, thereby increasing the amount of water used to clean the inner wall of the fixed retaining ring 2.

[0038] Example 4: Based on Example 3, Figure 9 and Figure 10As shown, it also includes a second fixed block 19, which is fixed to the left front side of the fixed base 1. The second fixed block 19 is rotatably connected to the guide rod 20, and the front side of the guide rod 20 is slidably connected to the clamping rod 21 along the up and down directions. A third spring 22 is fixed between the guide rod 20 and the clamping rod 21. The second fixed block 19 has two front and rear clamping holes, and the clamping rod 21 is clamped in one of the clamping holes.

[0039] During depilation, the guide rod 20 is in the fixed base 1, and the rotating frame 6 drives the feathers to rotate clockwise. During the rotation, the feathers are blocked and guided by the guide rod 20 and discharged from the drain outlet of the fixed base 1. When the rotating frame 6 stops rotating, the movable retaining ring 3 opens upward, and the hot water flushes the feathers in the fixed base 1 to the periphery, causing some feathers to be blocked on the left side of the guide rod 20. At this time, the guide rod 20 is turned clockwise, and the guide rod 20 drives the clamping rod 21 to rotate. The second fixed block 19 squeezes the clamping rod 21 to slide downward, and the third spring 22 is compressed, so that the clamping rod 21 and the front side are connected. When the card rod 21 is disengaged from the second fixing block 19, the third spring 22 is reset to drive the card rod 21 to slide upward. When the card rod 21 rotates to contact the second fixing block 19 again, the second fixing block 19 squeezes the card rod 21 again to slide downward, and the third spring 22 is compressed again until the card rod 21 rotates to align with the card hole on the rear side. At this time, the third spring 22 is reset to drive the card rod 21 to slide upward and be stuck in the card hole on the rear side. In this way, the guide rod 20 is rotated out of the fixed base 1, so that the feathers blocked on the left side of the guide rod 20 can be discharged with the water later.
