Description

Technical Field

[0001] This utility model belongs to the field of poultry gizzard processing technology, and more specifically, it relates to a poultry gizzard cutting device. Background Technology

[0002] In poultry slaughtering, automatic gutting equipment initially separates the chicken's internal organs. After this initial separation, the gizzard needs to be cut open, and the undigested food inside removed before cleaning. However, because the gizzard, after initial separation by the automatic gutting equipment, is connected to the foregut and stomach, the current method for cutting the gizzard typically involves manual handling with a knife. First, the foregut and stomach are cut and separated from one end of the gizzard in two stages. Then, the gizzard is cut in half lengthwise while the knife is held in one hand and one hand is pressed down on one side. Afterward, a hose is used to clean the cut gizzard. Finally, the stomach is manually opened for later cleaning of internal waste. The entire process of cutting chicken gizzards requires long hours of manual labor, which is time-consuming and labor-intensive. Prolonged manual cutting can easily lead to cutting deviations, damaging the yellow skin of the gizzard and affecting the cutting quality. This results in low cutting efficiency, low cutting precision, and low safety, making it unsuitable for mass production. Furthermore, after cutting and separating the gizzard, foregut, and stomach, there is a significant amount of meat scraps and liquid attached. During loading and subsequent cutting, the surface of the raw materials needs to be cleaned manually, increasing loading time and transport weight. During cutting, it is extremely easy to slip, leading to cutting difficulties or even splitting the gizzard and stomach in two, resulting in overall low cutting efficiency, low cutting precision, and low safety.

[0027] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 1 and Figure 4 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 1 and Figure 4 The direction of the center of a specific component is the same as the direction in which the conveying device transports the chicken gizzards, as mentioned throughout the text, which is the same as the direction in which the conveying device transports the chicken gizzards.

[0028] The most crucial concept of this utility model lies in: the automatic feeding, conveying, and filtering of chicken gizzards, stomachs, and foreguts via the feeding elevator and filter plate 43; the initial positioning and automatic conveying of chicken gizzards and foreguts via the fixed seat 3, limiting groove 4, clearance hole 6, and conveying device 2; the limiting group at the front of the conveying device 2 to limit the fixed seat 3 and to initially limit the foregut and stomach; the upper pressing mechanism to limit and press the upper end of the chicken gizzard; and the side pressing mechanism to hold the stomach and foregut together. The stomach is initially confined to one side of the front limiting plate assembly; the front cutter 7, the rear cutter assembly, and the drive mechanism automatically cut the chicken stomach and separate the foregut and stomach from the gizzard; the rotating push assembly automatically rotates the fixed seat 3 containing the separated gizzard 90°; the rear limiting plate assembly automatically limits the fixed seat 3 after rotating 90°; the vertical circular blade 5 and the drive mechanism automatically rotate and cut the gizzard; and the cleaning mechanism automatically cleans the inside of the cut gizzard.

[0029] The system boasts a high degree of automation, automatically conveying and limiting multiple chicken gizzards, stomachs, and foreguts. It employs fixed vertical circular blades 5 and a front cutting blade 7 to prevent the gizzards and stomachs from being cut in half or having their skin damaged, ensuring the quality of the cut. Furthermore, the system automatically filters out liquids and meat scraps during loading and transport, eliminating the need for manual transport. Overall, it offers advantages such as high cutting efficiency, high cutting precision, and good safety.

[0030] Please refer to Figures 1 to 9 As shown, a poultry gizzard cutting device includes a machine base 1. From front to back, the machine base 1 is equipped with a feeding elevator, a conveying device 2, and a cleaning mechanism. The lifting end of the feeding elevator is connected to a filter plate 43 for placing chicken gizzards. Several fixed seats 3 are rotatably connected to the conveying device 2. Each fixed seat 3 has a limiting groove 4 for placing chicken gizzards. From front to back, the conveying device 2 is equipped with a front limiting plate assembly to prevent the fixed seats 3 from rotating, a rotating pushing assembly to push the fixed seats 3 to rotate 90°, and a rear limiting plate assembly to prevent the fixed seats 3 from rotating. A vertical circular blade 5 for cutting chicken gizzards is mounted on the upper middle of the plate assembly. Both sides of the limiting groove 4 are connected to clearance holes 6 for placing one end of the chicken stomach and for the vertical circular blade 5 to pass through. A side pressing mechanism for pressing the chicken belly and chicken stomach to one side is mounted on one side of the front limiting plate assembly. A front cutter 7 and a rear cutter assembly are used to cut the two ends of the chicken belly and chicken stomach respectively. A downward pressing mechanism for pressing the upper end of the chicken gizzard is mounted on the upper part of the front limiting plate assembly and the rear limiting plate assembly. The machine base 1 is equipped with a drive mechanism to drive the front cutter 7, the rear cutter assembly and the vertical circular blade 5 to rotate.

[0031] As described above, when cutting the connected chicken gizzard, stomach, and foregut, firstly, the initially separated chicken gizzard, stomach, and foregut fall to the bottom input end of the feeding elevator. The feeding elevator and filter plate 43 then transport the chicken gizzard, stomach, and foregut towards the machine platform 1. The chicken gizzard, stomach, and foregut fall together onto the filter plate 43. Using gravity, any liquid or meat scraps adhering to the chicken gizzard, stomach, and foregut fall through the filter plate 43, achieving automatic material conveying and filtering of the chicken gizzard, stomach, and foregut to be cut. No manual handling is required, avoiding the impact of liquid and meat scraps on the subsequent cutting accuracy and efficiency of the chicken gizzard, stomach, and foregut. Then, through the fixed seat 3, limiting groove 4, clearance hole 6, and conveying device 2, the machine... The worker or robot places the chicken gizzards that have fallen onto the machine table 1 into the limiting groove 4 in sequence. The end of the chicken stomach connected to the chicken gizzard is placed into the clearance hole 6, which plays a role in automatically conveying the chicken gizzard, chicken belly, and chicken stomach, and automatically positioning one end of the chicken gizzard and chicken stomach. The front limiting group is used to prevent the fixed seat 3 located at the front of the conveying device 2 from rotating. At the same time, the other end of the chicken belly and chicken stomach connected to the chicken gizzard placed in the limiting groove 4 is perpendicular to one side of the front limiting plate group under the action of gravity, which facilitates the subsequent cutting of the chicken belly and chicken stomach. It plays a role in positioning the fixed seat 3 and initially limiting the chicken stomach and chicken belly. It avoids the fixed seat 3 from shifting or the chicken belly and chicken stomach from stacking, which would affect the overall cutting efficiency and cutting quality, and further improve the overall cutting efficiency and cutting accuracy.

[0032] Then, as the chicken belly and foregut are conveyed along with the gizzard towards the front cutter 7, the upper end of the gizzard on the fixed seat 3 is pressed by the upper pressing mechanism located above the front limiting plate assembly, preventing the gizzard from being pulled off the fixed seat 3 when cutting the chicken belly and foregut later, thus providing a second limiting effect on the gizzard; the side pressing mechanism limits and lightly presses the vertical chicken belly and foregut against one side of the front limiting plate assembly, providing an initial limiting effect on the chicken belly and foregut; ensuring that the chicken belly and foregut are perpendicular to one side of the front limiting plate assembly; then the front cutter 7 and the drive mechanism start the drive... The drive mechanism drives the front cutter 7 to rotate and cut the middle part of the chicken belly, thus automatically cutting the chicken belly. Because the distance between the front cutter 7 and the front limit plate is fixed on one side, compared with manual cutting, it avoids the situation of cutting the chicken belly in two, thereby further ensuring the cutting quality, cutting accuracy and cutting efficiency. After cutting, the chicken belly continues to move together with the chicken stomach and gizzard. Through the rear cutter group and the drive mechanism, the drive mechanism drives the rear cutter group to rotate, thereby cutting off both ends of the chicken stomach, thus automatically separating the chicken stomach and gizzard from the gizzard.

[0033] After the secondary separation, the chicken gizzards are conveyed by the conveyor 2 to the rotary push assembly. The rotary push assembly rotates the fixed seat 3 by 90°, so that the clearance hole 6 is in the middle of the rear limit plate assembly. The rear limit plate assembly is used to limit the fixed seat 3 after rotating 90°, preventing the fixed seat 3 from rotating and affecting the subsequent cutting accuracy and efficiency, thus further ensuring cutting efficiency and accuracy. Then, through the upper pressing mechanism, the vertical circular cutter 5, and the drive mechanism, the upper pressing mechanism is first used to press the upper end of the chicken gizzard again to prevent the chicken gizzard from shaking during subsequent cutting, and then the drive mechanism is used to press the upper end of the chicken gizzard again to prevent the chicken gizzard from shaking during subsequent cutting. The mechanism drives the vertical circular blade 5 to rotate and cut the chicken gizzard along the clearance hole 6, which serves to limit the chicken gizzard again and automatically rotate and cut it. Finally, when the chicken gizzard is transported to the output end of the conveying device 2 after cutting, the yellow skin inside the cut opening of the chicken gizzard is cleaned by the cleaning mechanism, which automatically cleans the chicken gizzard after cutting. The empty fixed seat 3 after feeding is transported to the lower conveying end face of the conveying device 2. The rotating push component located on the lower conveying end face automatically rotates and resets the fixed seat 3. The overall automation level is high, and it has the advantages of high cutting efficiency, good cutting effect, high cutting accuracy and safety.

[0034] Furthermore, the side-pressing mechanism includes an upper pressure plate 10 for side-pressing the other end of the chicken's foregut and a lower pressure plate 11 for side-pressing the chicken's belly. A support plate 12 is connected to one side of the front limiting plate assembly. An upper limit channel 13 that gradually narrows along the chicken gizzard conveying direction is formed between the support plate 12 and the upper pressure plate 10. Both the upper pressure plate 10 and the support plate 12 are provided with upper limit holes 14 for the rear cutting blade assembly to pass through. A lower limit channel that gradually narrows along the chicken gizzard conveying direction is formed between the lower pressure plate 11 and the front limiting plate assembly. The lower pressure plate 11 of the channel 15 has a lower limit hole 16 for the front cutter 7 to pass through. The machine base 1 is equipped with a support 17 located on the side of the lower pressure plate 11 away from the front limit plate group. The upper pressure plate 10 and the lower pressure plate 11 are both connected to guide rods 18. The support 17 is equipped with a sleeve 19 for the guide rods 18 to slide through along the width direction of the conveying device 2. A side spring sleeved on the outside of the guide rod 18 is connected between the sleeve 19 and the upper pressure plate 10 and between the sleeve 19 and the lower pressure plate 11.

[0035] As described above, when the chicken belly and foregut are transported to the side-pressing mechanism along with the gizzard, the chicken belly enters the lower limit channel 15. The lower pressure plate 11 gradually adjusts the lateral pressure of the chicken belly to ensure that it lightly touches one side of the front limit plate assembly. The chicken foregut enters the upper limit channel 13. The upper pressure plate 10 and the support plate 12 gradually limit the other end of the chicken foregut (i.e., the end where the chicken foregut connects to the chicken belly). This prevents the chicken belly and foregut from contracting and stacking during subsequent cutting of both ends, which could lead to excessive cutting deviation or incorrect cutting. This further ensures the cutting effect and accuracy. By setting side springs and supports... The seat 17 utilizes the elastic force of the side spring to facilitate the adjustment of the pressure of the upper pressure plate 10 and the lower pressure plate 11 on chicken bellies or foreguts of different thicknesses. This allows the chicken bellies or foreguts to be cut to be pressed laterally onto one side of the front limiting plate group or the support plate 12, making it easier for the front cutter 7 and the rear cutter group to cut the chicken bellies and foreguts more effectively. The guide rod 18 and the sleeve 19 are used to ensure that the side springs extend and retract in a directional manner along the length of the guide rod 18, preventing the upper pressure plate 10 and the lower pressure plate 11 from shifting during the adjustment and movement of the chicken bellies or foreguts due to the offset of the side springs. This ensures that the side pressure mechanism can accurately adjust the chicken bellies or foreguts.

[0036] Furthermore, the pressing mechanism includes a long pressure plate 20 for pressing down the middle of the upper end of the gizzard, and a set of pressure rods 21 for pressing down both sides of the middle of the upper end of the gizzard. A front support and a rear support, both arranged in an inverted U-shape, are mounted on the machine base 1. A front T-shaped rod 24 slides down and down through the top of the front support. A front spring 22 connects the long pressure plate 20 to the top of the front support. The vertical section of the front T-shaped rod 24 passes through the front spring 22, and its bottom is connected to the top of the long pressure plate 20. The top of the rear support... A set of rear T-shaped rods 25 are provided for upward and downward sliding. A rear spring 23 is connected between the pressure rod 21 and the rear support. The vertical section of the rear T-shaped rod 25 passes through the rear spring 23 and its bottom is connected to the top of the pressure rod 21. The vertical disc knife 5 is located between a set of pressure rods 21. A front downward pressing channel 26 is formed between the conveying device 2 and the long pressure plate 20, which is gradually narrowed in the direction of chicken gizzard conveying. A rear downward pressing channel 27 is formed between the conveying device 2 and the pressure rod 21, which is gradually narrowed in the direction of chicken gizzard conveying.

[0037] As described above, the chicken gizzards between the front limiting groups are first conveyed into the front lowering channel 26 via the long pressure plate 20, the front bracket, the front T-shaped rod 24, the front spring 22, and the front lowering channel 26. The long pressure plate 20 gradually limits and presses the upper middle part of the chicken gizzards in the front lowering channel 26. Under the elastic force of the front spring 22, the pressure of the lower pressure plate 11 on the upper end of chicken gizzards of different thicknesses is adjusted, thereby limiting and pressing the upper ends of chicken gizzards of different thicknesses at the front of the conveying device 2. Similarly, through a set of pressure rods 21, a rear support, a rear T-shaped rod 25, a rear spring 23, and a rear downward pressing channel 27, when the chicken gizzards between the rear limiting groups are conveyed into the rear downward pressing channel 27, the pressure rods 21 are used to gradually limit and press the upper middle part of the chicken gizzards in the rear downward pressing channel 27. The elastic force of the rear spring 23 is used to adjust the pressure of the pressure rods 21 on the upper middle part of chicken gizzards of different thicknesses, thereby limiting and pressing the upper ends of chicken gizzards of different thicknesses in the rear section of the conveying device 2.

[0038] Furthermore, the front limiting plate assembly includes two front vertical plates 28 located on both sides of the front section of the conveying device 2. The side of the fixed base 3 with the clearance hole 6 is a long side 29. The front vertical plates 28 are parallel to the long side 29 and are connected to the machine base 1. The top of the front vertical plates 28 is located between the bottom of the clearance hole 6 and the bottom of the fixed base 3. A front limiting channel 30 for the longitudinally placed fixed base 3 to pass through is formed between the two front vertical plates 28. The rear limiting plate assembly includes two rear vertical plates 61 located on both sides of the rear section of the conveying device 2. The rear vertical plates 61 are perpendicular to the long side 29 and are connected to the machine base 1. A rear limiting channel 31 for the transversely placed fixed base 3 to pass through is formed between the rear vertical plates 61.

[0039] As can be seen from the above description, the two front vertical plates 28 and the front limiting channel 30 are used to limit the long sides 29 on both sides of the fixed seat 3, so as to prevent the longitudinally placed fixed seat 3 from rotating; the two rear vertical plates 61 and the rear limiting channel 31 are used to limit the other two sides of the fixed seat 3, so as to prevent the horizontally placed fixed seat 3 from rotating.

[0040] Furthermore, the rotary pushing assembly includes a blocking block 32 and a limiting block 33. A rotating disk 34 is connected between the bottom center of the fixed base 3 and the conveying end face of the conveying device 2. The blocking block 32 and the limiting block 33 are respectively mounted on both sides of the upper conveying end face of the conveying device 2, and a middle limiting channel 35 is formed between them for the middle of the bottom of the horizontally placed fixed base 3 to pass through. Both sides of the bottom of the fixed base 3 are provided with clearance slots 36 for the blocking block 32 and the limiting block 33 to pass through. The clearance slots 36 have only one side wall and an upper end wall, and are located in Between the two long sides 29; the vertical distance between the side of the blocking block 32 near the limiting block 33 and the center of the rotating disk 34 is greater than the vertical distance between the side wall of the clearance groove 36 and the center of the rotating disk 34, and less than the vertical distance between the long side 29 and the center of the rotating disk 34. The front end of the limiting block 33 is provided with an area for the bottom middle of the fixed seat 3 to rotate. The lower conveying end face of the conveying device 2 is also provided with a blocking rod and a limiting baffle that block one side of the long side 33 of the horizontally placed fixed seat 3 and drive the fixed seat 3 to rotate.

[0041] As described above, when the gizzard, after the separation of the chicken belly and foregut, is conveyed away from the pressing mechanism above the front limiting plate assembly along with the fixed seat 3, one side of the moving fixed seat 3 is blocked by the blocking block 32 and rotates around the center of the rotating disk 34 towards the direction closer to the limiting block 33. This continues until the long side 29 of the fixed seat 3 rotates from parallel to the conveying direction of the conveying device 2 to perpendicular to the conveying direction, i.e., after the fixed seat 3 has rotated 90°. Because the vertical distance 'a' between the side of the blocking block 32 near the limiting block 33 and the center of the rotating disk 34 is greater than the vertical distance 'b' between the side wall of the clearance groove 36 and the center of the rotating disk 34, and less than the vertical distance between the long side 29 and the center of the rotating disk 34, the front end of the limiting block 33 is provided for the center of the bottom of the fixed seat 3 to rotate. In region c, the side wall of the clearance channel 36 is located between the limiting block 33 and the blocking block 32, that is, the bottom middle of the fixed seat 3 is located in the middle limiting channel 35. The middle limiting channel 35 is used to prevent the fixed seat 3 from rotating again before entering the rear limiting plate group, thereby realizing the function of automatically driving the fixed seat 3 to rotate 90°. When the empty fixed seat 3 after material discharge is transported to the lower conveying end face of the conveying device 2, it is first limited by the rear limiting plate group, and then pushed to rotate 90° by the blocking rod and limiting baffle of the lower conveying end face. The principle of the blocking rod and limiting baffle is the same as that of the blocking block 32 and the limiting block 33, which will not be described again here. The horizontal fixed seat 3 rotates again to the vertical position, and then is limited by the front limiting component and transported to the upper conveying end face of the conveying device 2 again.

[0042] Furthermore, the rotary pushing assembly includes a push plate 37, a push cylinder 38 mounted on one side of the conveying device 2, and a photoelectric switch. There are two push plates 37, two push cylinders 38, and two photoelectric switches, which are symmetrically arranged on the upper and lower conveying end faces of the conveying device 2. The push rod of the push cylinder 38 is connected to the push plate 37. The bottom center of the fixed seat 3 is connected to the conveying end face of the conveying device 2 with a rotating disk 34. The bottom of the fixed seat 3 is connected to an anti-rotation plate 39 parallel to the long side 29. The anti-rotation plate 39 is located between the rotating disk 34 and the long side 29. The conveying end face of the conveying device 2 is connected to several positioning plates 40 parallel to its conveying direction and used to block the anti-rotation plate 39. The positioning plates 40 are located below the fixed seat 3. The end of the push plate 37 away from the front vertical plate 28 is connected to a horizontal plate 41 to prevent the horizontal fixed seat 3 from reversing.

[0043] As described above, when the chicken gizzard, after the separation of the chicken belly and foregut, is conveyed away from the pressing mechanism above the front limit plate group along with the fixed seat 3, the photoelectric switch will detect the presence of the fixed seat 3 and send a signal to the external controller. The external controller controls the pusher cylinder 38 to start, the pusher cylinder 38 extends, and drives the pusher plate 37 to quickly push the conveying tail end of the fixed seat 3, causing the fixed seat 3 to rotate 90° quickly. This causes the anti-rotation plate 39 to rotate until it contacts the positioning plate 40, preventing the fixed seat 3 from rotating more than 90°. Through the horizontal plate 41, it is prevented that the fixed seat 3 will reverse under the action of inertia after rotating 90° quickly, thus achieving the function of automatically pushing the fixed seat 3 to rotate 90°. When the empty fixed seat 3 after discharge is conveyed to the lower conveying end face of the conveying device 2, the rotating pushing component of the lower conveying end face of the conveying device 2, in the same principle as above, causes the horizontally placed fixed seat 3 to rotate again to a vertically placed state, and then, after being limited by the front limit component, it is conveyed again to the upper conveying end face of the conveying device 2.

[0044] Furthermore, the rear cutting blade assembly includes an upper disc blade 8 for cutting one end of the chicken's foregut and a lower disc blade 9 for cutting the other end of the chicken's foregut. Both the lower disc blade 9 and the front cutting blade 7 are horizontal disc blades, while the upper disc blade 8 is a vertical disc blade. A support plate 42 supporting one end of the chicken's foregut is connected to one side of the top of the front limiting plate assembly. The front end of the support plate 42 is tapered in the opposite direction to the chicken gizzard conveying. A through hole is provided at the top of the support plate 42 for the bottom of the upper disc blade 8 to rotate through. The driving mechanism includes a first motor 44, which is mounted on the machine base 1 and is used to drive the front cutting blade 7 to rotate, a second motor 45, which drives the upper disc blade 8 to rotate, and a third motor 46, which drives the lower vertical disc blade 5 to rotate. A synchronous transmission mechanism 47 is connected between the lower disc blade 9 and the front cutting blade 7.

[0045] As described above, when the chicken belly is transported to the front cutter 7, the drive end of the first motor 44 rotates, causing the front cutter 7 to rotate and cut the chicken belly. After that, the cut chicken belly and the foregut are transported together with the gizzard to the rear cutter group. The second motor 45 drives the upper disc cutter 8 to rotate and cut one end of the foregut in the through hole of the support plate 42. At the same time, under the transmission action of the synchronous transmission mechanism 47, the lower disc cutter 9 rotates and cuts the other end of the foregut, thereby realizing the automatic cutting of the chicken belly and the automatic cutting of both ends of the foregut.

[0046] Furthermore, the cleaning mechanism includes a support frame 48, a cleaning water pipe 49 for cleaning the inside of the chicken gizzard, and a separating plate 50 for opening the chicken gizzard incision. The cleaning water pipe 49 and the separating plate 50 are respectively installed at the upper and lower ends of the support frame 48. The separating plate 50 is tapered toward the conveying device 2. One end of the cleaning water pipe 49 is connected to a nozzle 51 located above the output end of the conveying device 2. The nozzle 51 is inclined downward toward the output end of the conveying device 2. The other end of the cleaning water pipe 49 is connected to an external water source. A hopper 52 for collecting chicken gizzards is provided below the output end of the conveying device 2.

[0047] As described above, after the chicken gizzard is cut by the vertical circular blade 5, it is continued to be transported to the output end of the conveying device 2. The separation plate 50 is used to gradually open the cut of the chicken gizzard. The cleaning water pipe 49 draws water from the external water source and sprays it onto the chicken gizzard and the front end of the separation plate 50 through the nozzle 51. The undigested food inside the chicken gizzard is separated from the chicken gizzard under the rinsing of gravity and water, which plays the role of automatically cleaning the inside of the chicken gizzard. The feed hopper 52 is used to collect the cleaned chicken gizzard.

[0048] Furthermore, the feeding elevator includes a feeding conveyor 54 and a distribution hopper 53 mounted above the input end of the conveying device 2. The feeding conveyor 54 is equipped with a conveyor belt. The conveying device 2 has two sets arranged side by side along its width direction. The front sides of the machine base 1 are equipped with feeding areas 55. The distribution hopper 53 is equipped with two distribution channels 56 that communicate with the feeding areas 55. The feeding conveyor 54 is inclined upward towards the input end of the conveying device 2. The output end of the feeding conveyor 54 is connected to a feeding hopper 57 that is inclined downward towards the distribution hopper 53. Several filter plates 43 are provided and are arranged alternately along the conveying direction of the conveyor belt. The length of the filter plate 43 is half the width of the conveyor belt. A rotating frame is installed at the end of the feeding conveyor 54 away from the conveying device 2. The rotating frame is rotatably connected to a guide plate 58 that is inclined downward towards the input end of the conveyor belt.

[0049] As described above, after initial separation, chicken gizzards containing the stomach and foregut are first transported from the previous process to the input end of the feeding conveyor 54. Then, they are filtered and transported to the top of the input end of the conveying device 2 by the interlaced filter plates 43 on the conveyor belt. After being buffered by the feed hopper 57, they fall to the distribution hopper 53. Under the action of gravity, after being separated by the two separation channels of the distribution hopper 53, two batches of chicken gizzards containing the stomach and foregut fall to the feeding areas 55 on both sides of the front end of the machine 1. This makes it easy for manual placement of the chicken gizzards containing the stomach and foregut into the limiting groove 4. By setting the length of the filter plate 43 to the width of the conveyor belt, the small size of the chicken gizzards, foregut, and stomach is avoided, which prevents a large amount of chicken gizzards from being transported to the machine 1 at one time and causing excessive accumulation in the feeding area 55.

[0050] Furthermore, the bottom two sides of the limiting groove 4 are provided with lower anti-slip ridges 60, and the upper two sides of the limiting groove 4 are provided with upper anti-slip ridges 59.

[0051] As can be seen from the above description, the upper anti-slip ridges 59 and the lower anti-slip ridges 60 increase the friction between the gizzard and the limiting groove 4, preventing the gizzard from moving too much or falling off the fixed seat 3 during transportation and rotation, and further ensuring the positioning of the gizzard by the fixed seat 3.

The upper pressing mechanism serves to limit and press the upper end of the gizzard between the front and rear limiting groups; the side pressing mechanism serves to initially limit the chicken belly and foregut; the front cutter 7, the rear cutter group, and the drive mechanism automatically cut the chicken belly and automatically separate the foregut and chicken belly from the gizzard; the rotating push assembly automatically rotates the fixed seat 3 containing the separated gizzard by 90°; the rear limiting plate group automatically limits the fixed seat 3 after rotating 90°; the vertical circular cutter 5 and the drive mechanism automatically rotate and cut the gizzard; and the cleaning mechanism automatically cleans the inside of the cut gizzard.

[0063] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
