[0030] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0031] Embodiment 1 like Figure 1 As shown, a duck gizzard processing device with uniform and stable morphological distribution comprises: A conveying mechanism 1, which is used to convey duck gizzards and includes a frame 11 and a conveyor belt 12; A cutting mechanism 2, which is used to cut the duck gizzards into continuous spirals, and includes a positioning component 21 for positioning the duck gizzards and a cutting component 22 for cutting the gizzards after positioning; A film scraping mechanism 3, which is arranged behind the cutting mechanism 2 and is used to scrape off the gizzard lining on the surface of the duck gizzard; The stringing mechanism 4 is arranged behind the film scraping mechanism 3 and is used to cooperate with the positioning assembly 21 to complete the stringing; The pickling mechanism 5 is arranged behind the delivery mechanism and is used for pickling the duck gizzards.

[0032] In this embodiment, by setting a cutting mechanism 2, a scraping mechanism 3, a stringing mechanism 4 and a pickling mechanism 5, the steps of cutting, scraping, stringing and pickling of duck gizzards are completed in sequence. During the entire processing process, the cutting mechanism 2 is used to cut the duck gizzards into continuous spirals, and its shape is similar to the spiral shape of common roasted gluten, thereby ensuring that the finished duck gizzard skewers are easy to bake and eat. At the same time, by first processing the shape of the duck gizzards, it is convenient for the subsequent scraping, stringing and pickling of the duck gizzards.

[0033] In detail, the production of duck gizzard skewers is mostly done manually, where the gizzards are cut manually and then strung into strings for subsequent processing. This method requires a lot of labor and is not conducive to ensuring the stability of the shape of each string of duck gizzards.

[0034] It should be noted that the duck gizzard is the muscular stomach of the duck. After it is cut open from the weak position in the middle, its shape is approximately two semi-ellipsoids connected by the middle fascia, and the duck gizzard is attached to the inner wall. Due to the wrinkles on the inner wall of the duck gizzard, the duck gizzard is not easy to remove and is usually scraped off manually.

[0035] It is worth mentioning that, in order to facilitate the processing of duck gizzards, the conveyor belt 12 in the conveying mechanism 1 can adopt two vertical conveyor belts, through which the duck gizzards are clamped and conveyed forward, and a smooth support rod is set under the vertical conveyor belt to prevent the duck gizzards from falling. The middle of the support rod is hollow, which is convenient for setting various subsequent mechanisms. Further, if Figure 2 , Figure 3 As shown, the positioning assembly 21 includes a first slider 211 slidably connected to the conveying mechanism 1, a positioning block 212 vertically slidably connected below the first slider 211 and driven to rise and fall by an electric cylinder, a calibration frame 213 vertically slidably connected to the lower end of the positioning block 212 and having a spring between the calibration frame 212, a positioning roller 214 arranged at the lower end of the calibration frame 213, and two sets of balance wheels 215 horizontally slidably connected to both sides of the calibration frame 213.

[0036] In this embodiment, by providing a positioning roller 214 and a balancing wheel 215, the position of the middle fascia of the gizzard is determined, so that the fascia can be avoided during the subsequent cutting and stringing process to prevent the gizzard from being cut off from the middle fascia during cutting.

[0037] In detail, the positioning block 212 descends, causing the calibration frame 213 and the positioning roller 214 to descend. When the gizzard passes under the positioning block 212, the gizzard lifts the positioning roller 214. As the gizzard moves, the positions of the balancing wheels 215 on both sides change. When the gizzard moves in, the balancing wheel 215 on the left is displaced. When the gizzard moves out, the balancing wheel 215 on the right is displaced. When the positioning roller 214 moves to the middle fascia position, the positions of the balancing wheels 215 on both sides remain equal. At this time, the positioning roller 214 is located at the thinnest part of the middle fascia of the gizzard.

[0038] It should be noted that due to the structure of the duck gizzard, after being cut, it is connected by a narrow fascia in the middle. The texture of the fascia is completely different from that of the muscles on both sides. Therefore, not only does the fascia need to be avoided during the cutting process, but the fascia also needs to be avoided during the stringing of the beard to achieve a better stringing effect and ensure a smooth stringing process.

[0039] Further, if Figure 4, Figure 5 As shown, the slitting assembly 22 includes a lifting rod 221 arranged below the positioning roller 214 and controlled to vertically lift by an electric cylinder, a displacement frame 222 arranged below the calibration frame 213 and horizontally slidably connected to the frame 11, two groups of cutters 223 respectively rotatably connected to both ends of the displacement frame 222, and fixed needles 224 at both ends of the displacement frame 222 and with their center lines arranged in the middle of the rotation trajectory.

[0040] In this embodiment, the cutting of the duck gizzard is achieved by providing a cutting knife 223 .

[0041] In detail, after the positioning roller 214 positions the fascia in the middle of the gizzard, the positioning block 212 moves downward, and the lifting rod 221 moves downward to move the gizzard to the top of the cutter 223. The fixing needles 224 at both ends move toward the middle, and the ends of the gizzard are fried to fix the gizzard. The cutter 223 rotates along the displacement frame 222 and the displacement frame 222 moves from one end to the other. The cutter 223 rotates around the gizzard and moves horizontally to cut the gizzard into a continuous spiral. The muscles on both sides are connected by the fascia in the middle.

[0042] It should be noted that in the existing cutting method, the cut duck gizzard slices are threaded into bamboo skewers. Since the duck gizzards shrink during the baking process, if the threading effect is not good, the duck gizzards are likely to fall off the bamboo skewers. Therefore, the duck gizzards are cut into continuous spiral shapes to prevent the duck gizzards from falling off due to shrinkage during the baking process.

[0043] It is worth mentioning that, since the gizzard is solid, the depth of the cutter 223 penetrating into the gizzard does not need to be slightly greater than the radius of the gizzard. At the same time, the depth of the fixing needle 224 inserted into the gizzard should not be too great to affect the movement of the cutter 223.

[0044] Further, if Figure 6 As shown, the scraping mechanism 3 includes a separation component 31 for separating the cut gizzards and a cleaning component 32 for scraping the surface of the gizzards, the separation component 31 includes two groups of separation clamps 311 arranged under the conveyor belt 12 and controlled to move horizontally by an electric cylinder, two groups of lifting plates 312 arranged on both sides of the conveyor belt 12 and controlled to move up and down by an electric cylinder, an isolation plate 313 horizontally slidably connected to the lifting plate 312, a rocker arm 314 arranged on the outside of the isolation plate 313, a swing rail 315 fixed on the frame 11 close to the rocker arm 314, and multiple groups of clips 316 slidably connected to the inside of the isolation plate 313 through a screw rod.

[0045] In this embodiment, by providing the separation clamping claws 311 and the clamping pieces 316, the cut gizzard slices can be clamped, and the gizzard lining on the inner wall can be scraped off.

[0046] In detail, the cut gizzards are moved to the middle of the two sets of separation claws 311, the separation claws 311 clamp the two ends of the gizzards, stretch the gizzards, separate the gizzard slices, and then the isolation plate 313 descends. During the descent, it swings left and right under the action of the swing rod 314 and the swing rail 315, so that the clamping piece 316 can extend into the middle of the gizzard slices, and the clamping piece 316 clamps the gizzard slices for subsequent scraping work.

[0047] Further, if Figure 7 , Figure 8 As shown, the cleaning member 32 includes a pressure rod 321 respectively arranged above the two groups of separation jaws 311, a control block 322 arranged below the pressure rod 321 and slidably connected to the frame 11 along the moving direction of the conveyor belt 12, a reciprocating plate 323 horizontally slidably connected to the control block 322 perpendicular to the moving direction of the conveyor belt 12, and two groups of scrapers 324 vertically slidably connected to the reciprocating plate 323 and with springs arranged between the reciprocating plate 323.

[0048] In this embodiment, the inner wall of the gizzard is scraped off by providing a pressure rod 321 and a scraper 324 in cooperation with the clamping piece 316 to clamp the gizzard slice.

[0049] In detail, after the clip 316 fixes the gizzard, the pressure rod 321 moves downward to press the middle of the gizzard downward, so that the inner wall of the lower part of the gizzard, which is originally approximately flat, is pushed outward in the middle, so that the folds on the inner wall can be expanded as much as possible, and the scraper 324 is moved to scrape off the surface gizzard.

[0050] It should be noted that, because there are wrinkles on the inner wall of the gizzard, if the entire gizzard is directly scraped, it is limited by the shape and size of each gizzard, so it is very difficult to complete it through a mechanical structure. However, if the gizzard is cut and then scraped, the thickness of each gizzard piece can be close. The two ends of the gizzard are clamped by the clamping piece 316, and the middle part is pressed down by the pressure rod 321 to lift the middle position of the gizzard. The inner walls of each gizzard piece can be close to each other and can be uniformly processed by the scraper 324.

[0051] Further, if Fig. 9 As shown, the stringing mechanism 4 includes a groove roller 41 arranged behind the scraping mechanism 3 and driven by a motor, a sign box 42 arranged above the tank, a telescopic cylinder 43 arranged on the outside below the tank, and an extrusion piece 44 arranged in front of the groove roller 41.

[0052] Further, if Fig. 9 , Fig.10As shown, the extrusion member 44 includes a baffle 441 arranged in front of the groove roller 41 and rotatably connected to the frame 11 through a torsion spring, a push plate 442 arranged in front of the baffle 441, a slide groove 443 for driving the push plate 442 to move along the direction of the conveyor belt 12, and the slide groove 443 is vertically slidably connected to the frame 11, a cam 444 arranged below the slide groove 443 and rotatably connected to the frame 11, and a first rack 445 arranged on the first slider 211 and driving the cam 444 to rotate through a gear rack transmission method.

[0053] In this embodiment, a telescopic cylinder 43 and an extruding member 44 are provided to cooperate with the positioning assembly 21 to complete the stringing of the duck gizzards.

[0054] In detail, the duck gizzard moves to the front of the baffle 441 and is stopped by the baffle 441. At the same time, the first slider 211 drives the cam 444 to rotate while moving, so that the push plate 442 rises, and then the push plate 442 moves to push the rear end of the duck gizzard. At the same time, the positioning block 212 moves down. The three cooperate to make the fascia in the middle of the duck gizzard bend downward, and then the positioning block 212 rises for threading, so that when the telescopic cylinder 43 pushes the bamboo skewer out, the bamboo skewer can avoid the fascia.

[0055] It should be noted that the bamboo skewers are placed in the skewers box 42, and the bamboo skewers are output in sequence by the rotation of the grooved roller 41, and the bamboo skewers are pushed into the duck gizzards by the telescopic cylinder 43 to complete the skewering.

[0056] It is worth mentioning that since the fascia in the middle of duck gizzard is not easy to puncture, if the bamboo stick is forced through the fascia, it is easy to cause the bamboo stick to be deflected or damaged.

[0057] Further, if Fig.11 As shown, the marinating mechanism 5 includes a sauce tank 51 arranged behind the skewering mechanism 4, a chain 511 arranged on both sides of the sauce tank 51 and driven by a motor, a restraining block 512 arranged on the chain 511, a restraining clamp 513 arranged on the restraining block 512, and two groups of wave plates 514 arranged above the chain 511 and controlled to move horizontally by an electric cylinder.

[0058] Further, if Fig.12 As shown, the pickling mechanism 5 further includes a restraining rail 515 disposed in the sauce tank 51 , a wedge-shaped clamping block 516 disposed at the rear section of the restraining rail 515 , and a kneading member 52 disposed above the sauce tank 51 .

[0059] Further, if Fig.12 , Fig.13As shown, the kneading member 52 includes a traction rail 521 arranged above the sauce tank 51, a traction block 522 slidably connected to the traction cabinet, a bamboo skewer clamp 523 hinged at the lower end of the traction block 522, and an extrusion plate 524 arranged below the bamboo skewer clamp 523 and controlled to move by an electric cylinder.

[0060] In this embodiment, the pickling process of the duck gizzards is completed by providing a pickling mechanism 5, which can, on the one hand, cover the surface of the duck gizzards with pickling, and on the other hand, avoid excessive pickling.

[0061] In detail, after the duck gizzard is skewered, it continues to move, moves out of the conveying mechanism 1, and falls obliquely downward into the sauce trough 51. At the same time, the upper end of the duck gizzard rests on the restraining block 512. The restraining claw 513 on the restraining block 512 clamps the upper end of the bamboo stick, driving the bamboo stick to move forward, and the top of the bamboo stick enters the middle of the wave plate 514. With the push of the wave plate 514, the duck gizzard at the lower part of the bamboo stick swings in the sauce trough 51, so that the surface of the duck gizzard is covered with marinade. Then, as the duck gizzard moves out of the wave plate 514, the bamboo stick clamp 523 clamps the top of the bamboo stick and pulls the duck gizzard out of the sauce trough 51. A restraining rail 515 is provided in the sauce trough 51 to assist the movement of the duck gizzard. At the same time, when the bamboo stick clamp 523 clamps the bamboo stick and moves upward, the squeezing plate 524 extends, pushing the duck gizzard on the bamboo stick, cooperating with the wedge-shaped block 516 on the restraining rail 515 to achieve squeezing of the duck gizzard.

[0062] It should be noted that the squeezing of the gizzards is accomplished by the cooperation of the squeezing plate 524 and the wedge-shaped block 516. On the one hand, this prevents the gizzards from containing too much marinade, which would cause excessive or uneven marinating. On the other hand, multiple squeezing can achieve a kneading effect on the gizzards, making it easier for the gizzards to absorb flavor.

[0063] It is worth mentioning that a conveyor belt is also provided at the rear of the traction machine, which is used for placing the duck gizzard skewers on the conveyor belt for subsequent freezing or packaging steps after the bamboo skewer clamp 523 takes out the duck gizzard skewers.
