Description

Technical Field

[0001] This utility model relates to the field of poultry slaughtering and processing equipment, and in particular to an automatic lifting device for a duck tail cutting machine. Background Technology

[0002] In poultry slaughtering and processing, the tail of poultry carcasses needs to be cut off for further processing. Currently, the tail-cutting process mainly occurs after the poultry carcass has been plucked, eviscerated, or pre-cooled. There are two main methods for tail-cutting:

[0003] The first method is manual tail cutting. Currently, most poultry processing plants in my country use manual tail cutting. This method is very labor-intensive and can cause cross-contamination of the poultry carcasses, leading to bacterial growth.

[0004] The second type involves machine tail cutting. A search revealed Chinese utility model patent CN210470859U, which discloses an automatic poultry tail cutting machine. The machine includes a frame and a poultry hanging conveyor installed on the frame for transporting poultry. The poultry hanging conveyor has a first beam and a second beam on both sides, which are connected to the frame. The first beam has a leg guide device, and the second beam has a tail cutting device and a back guide device arranged from top to bottom.

[0005] However, in actual use, workers have found that the existing tail-cutting methods of machinery have many limitations. These machines are often difficult to adapt to the differences in size of poultry of different breeds and growth stages. The height and angle of the tail-cutting device are inconvenient to adjust and not precise enough. When processing smaller poultry, the tail-cutting device may not be able to cut the tail accurately, resulting in incomplete tail cutting. When processing larger poultry, over-cutting may occur, which not only wastes poultry resources but also affects the appearance and quality of the product. Utility Model Content

[0023] Example 1

[0024] See Figures 1 to 3 This utility model provides an automatic lifting device for a duck tail cutting machine, including a frame 1, and a hanging conveyor, a leg guide mechanism, and a back guide mechanism installed on the frame 1 for conveying ducks. The frame 1 includes a rectangular top frame, and a column 2 is fixedly installed at each of the four corners of the top frame. A tail cutting mechanism 3 is slidably installed on two columns 2 on the same side. The tail cutting mechanism 3 includes a lifting seat 4 slidably installed on the column 2, an mounting plate 5 fixedly installed on the lifting seat 4, a cutting motor 6 fixedly installed on the mounting plate 5, and a cutter 7 fixedly installed on the output shaft of the cutting motor 6.

[0025] The duck carcass automatically slides into the leg guide mechanism and back guide mechanism under the drive of the poultry hanging assembly line. The leg guide mechanism and back guide mechanism adjust the posture of the duck carcass so that its tail naturally slides into the cutting range of the cutter 7. The tail of the poultry carcass is cut by the cutter 7.

[0026] Users can adjust the height of the tail-cutting mechanism 3 according to the size of the ducks to adapt to the size differences of different batches of meat ducks, ensuring that the tail-cutting effect of each meat duck is consistent, avoiding problems such as incomplete tail cutting or over-cutting caused by improper height, and improving the quality stability of the product.

[0027] The lifting seat 4 includes two sliding cylinders 8 that are slidably mounted on the column 2. The two sliding cylinders 8 are fixedly connected by a crossbeam 9, and the mounting plate 5 is fixedly mounted on the two crossbeams 9.

[0028] A rack 10 is fixedly installed on one side of each column 2 that is slidably connected to the lifting base 4;

[0029] Each slide cylinder 8 is fixedly provided with a fixed frame 11, and a gear 12 is rotatably provided on the fixed frame 11, which meshes with the rack 10.

[0030] The two gears 12 are fixedly connected by a transmission rod 13, and a worm gear 14 is fixedly installed in the middle of the transmission rod 13;

[0031] A lifting motor 15 is fixedly installed on the crossbeam 9, and a worm gear 16 is fixedly installed on the motor shaft of the lifting motor 15. The worm gear 16 is rotatably connected to the crossbeam 9, and the worm gear 16 meshes with the worm wheel 14.

[0032] When the automatic lifting device of the duck tail cutting machine is needed, the motor shaft of the lifting motor 15 rotates, which drives the worm 16 fixed on it to rotate. Since the worm 16 meshes with the worm wheel 14, the rotation of the worm 16 will drive the worm wheel 14 to rotate, which in turn drives the transmission rod 13 fixed on the worm wheel 14 to rotate synchronously.

[0033] The rotation of the transmission rod 13 will cause the gears 12 connected to its two ends to rotate together. Since the gears 12 mesh with the rack 10 fixed on one side of the column 2, the rotation of the gears 12 will drive the slide cylinder 8 to slide up or down along the column 2. The specific lifting direction is determined by the rotation direction of the lifting motor 15, thereby realizing the precise adjustment of the height of the cutter 7, so as to adapt to the differences in body size of different batches of meat ducks, ensuring that the tail cutting effect of each meat duck is consistent, avoiding problems such as incomplete tail cutting or over-cutting due to improper height, and improving the quality stability of the product.

[0034] Because the worm gear 14 and worm 16 have a self-locking function, the tail cutting mechanism 3 can reliably remain in the position after being adjusted to the appropriate height, ensuring that each duck can be tail-cut at a precise and stable cutting height, which greatly improves the stability, reliability and safety of the automatic lifting device of the duck tail cutting machine.

[0035] A bracket is fixedly installed on the upper end of a column 2 near the input end of the suspended assembly line. An infrared sensor 17 is fixedly installed on the bracket. The infrared sensor 17 and the lifting motor 15 form an electrical control circuit.

[0036] Infrared sensor 17 emits infrared light and continuously monitors the area in front of it. When the duck carcass enters the monitoring range of infrared sensor 17, the duck carcass will block or reflect the infrared light. After receiving this change signal, the receiver of infrared sensor 17 converts it into an electrical signal.

[0037] The electrical signal is transmitted to the control system of the lifting motor 15, which forms an electrical control circuit with it. After receiving the signal, the control system determines the arrival of the duck carcass according to the preset program and parameters, and controls the lifting motor 15 to start.

[0038] When this utility model is in use, the duck carcass automatically slides into the space between the leg guide mechanism and the back guide mechanism under the drive of the poultry hanging assembly line. The leg guide mechanism and the back guide mechanism adjust the posture of the duck carcass so that its tail naturally slides into the cutting range of the cutter 7. The tail of the poultry carcass is cut by the cutter 7.

[0039] Infrared sensor 17 emits infrared light and continuously monitors the area in front of it. When the duck carcass enters the monitoring range of infrared sensor 17, the duck carcass will block or reflect the infrared light. After receiving this change signal, the receiver of infrared sensor 17 converts it into an electrical signal.

[0040] The electrical signal is transmitted to the control system of the lifting motor 15, which forms an electrical control circuit with it. After receiving the signal, the control system determines the arrival of the duck carcass according to the preset program and parameters, and controls the lifting motor 15 to start and adjust the height of the tail cutting mechanism 3 to adapt to the body size differences of different batches of ducks. This ensures that the tail cutting effect of each duck is consistent, avoids problems such as incomplete tail cutting or over-cutting caused by improper height, and improves the quality stability of the product.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
