Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a device for threading duck intestines. Background Technology

[0002] Duck intestines are rich in protein, B vitamins, vitamin C, vitamin A, and trace elements such as calcium and iron, which are beneficial to human metabolism, nerves, heart, digestion, and vision. They can be prepared in various ways, including braising, stir-frying, roasting, and stewing, and are delicious, crispy, and flavorful, making them a favorite among diners.

[0003] Duck intestines are relatively long and thin, making them difficult to skewer. They are typically skewered manually, with a process time of 500-800 skewers per hour. While some skewering equipment has appeared on the market in recent years, its effectiveness still falls short of the requirements. For example, the existing technology "A Duck Intestine Skewering Machine" (CN111543464B) discloses a skewering machine including a frame and a skewering device, a skewer-adding device, and a skewer-pushing device mounted on the frame. The skewering device and the skewer-pushing device are arranged side-by-side, with the skewer-adding device positioned above the skewer-pushing device. The skewering device includes a skewering conveyor belt, a mold guide block, and a mold pressing block. Several skewering molds are evenly spaced on the skewering conveyor belt. The mold guide block is located at the feed end of the skewering conveyor belt, and the mold pressing block is positioned above the skewering conveyor belt. This utility model's duck intestine skewering machine achieves automated skewering of duck intestines through a skewering device, a skewer-attaching device, and a skewer-pushing device. The entire duck intestine does not need to be pre-cut into small sections, greatly improving skewering efficiency compared to traditional manual skewering. However, the patent describes in its specification

[0046] that "duck intestines are automatically torn apart during mold rotation, thus eliminating the need for manual cutting." Because duck intestines have good elasticity, tearing them apart can lead to inconsistent lengths for each section. Intestinal lengths that are too long may result in some sections not being threaded onto the skewers, while intestinal lengths that are too short may result in excessively large gaps between sections on the skewers. Inconsistent lengths on each skewer will affect the appearance of the duck intestine skewers. Utility Model Content

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] In the attached diagram, all identical reference numerals refer to the same components.

[0019] Example 1: like Figure 1-9 As shown, this utility model provides a duck intestine skewering device, including a frame 1, a skewer feeding mechanism 2, an intestine supply mechanism 3, a skewer loading mechanism 4, a skewering mechanism 5, and a cutting mechanism 6. The intestine supply mechanism 3, the skewer feeding mechanism 2, and the skewering mechanism 5 are all located at the top of the frame 1. Its characteristic is that: The skewer delivery mechanism 2 transports bamboo skewers to the bottom of the skewering mechanism 5 and transports the skewered duck intestines to its unloading end. The skewer delivery mechanism 2 includes a first chain plate type transport mechanism 21 set at the top of the frame 1. The right side of the first chain plate type transport mechanism 21 is higher than its left side, and each chain plate is equipped with a skewer receiving mold 22 that is compatible with the bamboo skewers. The bamboo skewers are transported by the cooperation of the first chain plate type transport mechanism 21 and the skewer receiving mold 22.

[0020] Specifically, the first chain plate type transport mechanism 21 of the label delivery mechanism 2 is set at the top of the frame 1 in the front-to-back direction, and a label receiving mold 22 is fixedly installed on each chain plate by bolts or bolts. The side wall of the first chain plate type transport mechanism 21 is equipped with a servo motor (60ms1-400w) using existing technology, which drives the first chain plate type transport mechanism 21 to run or stop through the servo motor equipped with a reducer.

[0021] Multiple receiving molds 22 are spliced ​​together to form a plate-shaped feeding structure as the first chain plate transport mechanism 21 rotates to the upper part, and the bamboo skewers are sent to the stringing process through this structure; the first chain plate transport mechanism 21 moves the distance of one receiving mold 22 each time through a servo motor.

[0022] The process of attaching the bamboo skewer, threading the skewers, and unloading the food is all completed within the range of the first chain plate conveyor 21. After attaching the bamboo skewer at the feeding end of the first chain plate conveyor 21, the bamboo skewers are sent to the middle of the first chain plate conveyor 21 for threading, and the threaded duck intestines are sent to the unloading end.

[0023] The sausage supply mechanism 3 is located on the right side of the middle part of the labeling mechanism 4. It is used to transport duck intestines. The sausage supply mechanism 3 includes a second chain plate type transport mechanism 31 set at the top of the frame 1. The end of the second chain plate type transport mechanism 31 closer to the labeling mechanism 2 is higher than the other end. Each chain plate is equipped with a forming lower mold 32 that is compatible with the duck intestines. The duck intestines are transported towards the labeling mechanism 2 by the cooperation of the second chain plate type transport mechanism 31 and the forming lower mold 32.

[0024] Specifically, the second chain plate type transport mechanism 31 of the sausage supply mechanism 3 is set at the top of the frame 1 in the left-right direction, and a forming lower mold 32 is fixedly installed on each chain plate by bolts or bolts. The side wall of the second chain plate type transport mechanism 31 is equipped with a servo motor (60ms1-400w) using existing technology. The second chain plate type transport mechanism 31 is driven to run or stop by the servo motor equipped with a reducer (PNF60-10).

[0025] Multiple forming lower molds 32 are spliced ​​together to form a plate-shaped intestine supply structure as the second chain plate type transport mechanism 31 rotates to the upper part, and the duck intestines are sent to the skewering process through this structure; the second chain plate type transport mechanism 31 moves the distance of one forming lower mold 32 each time through a servo motor.

[0026] The bamboo skewer loading mechanism 4 is located above the feeding end of the bamboo skewer feeding mechanism 2. It evenly places the bamboo skewers onto the feeding mechanism 2 for transport. The bamboo skewer loading mechanism 4 includes two vertically spaced mounting plates 401 positioned above the feeding end of the bamboo skewer feeding mechanism 2. Between the two mounting plates 401 are a guide plate 402, a baffle 403, a bamboo skewer loading main shaft 404, a brush main shaft 405, and a connecting rod 406. The two ends of the bamboo skewer loading main shaft 404 and the brush main shaft 405 are rotatably connected to the two mounting plates 401 via bearings. The brush main shaft 405 and the connecting rod 406 are both located at... Above the main shaft 404, a roller 407 is coaxially mounted on the main shaft 404. A brush 408 is coaxially mounted on the main shaft 405. An arc-shaped limiting plate 409 is mounted on the connecting rod 406, which is adapted to the circumferential surface of the roller 407 and extends to the bottom of the roller 407 between the roller 407 and the feeding mechanism 2. The unloading end of the guide plate 402 is located close to the roller 407 and its height is lower than the other end. The baffle 403 is located above the unloading end of the guide plate 402 and has a gap with the unloading end of the guide plate 402.

[0027] Specifically, two mounting plates 401, a guide plate 402, and a baffle 403 form a hopper structure, which is used to hold bamboo skewers and forms an outlet for the bamboo skewers through the gap between the guide plate 402 and the baffle 403.

[0028] A second geared motor 413 (6ys01-18) and a servo motor (60ms1-400w) equipped with a reducer (PNF60-10) are installed on a mounting plate 401. The servo motor is reduced in speed by the reducer and then connected coaxially to the upper skewer main shaft 404 through a coupling to drive the upper skewer main shaft 404 and the upper skewer roller 407 on it to rotate. The circumferential surface of the upper skewer roller 407 has a groove that matches the bamboo skewer. When the upper skewer roller 407 rotates, it causes the bamboo skewer to enter the groove and drives the bamboo skewer to rotate onto the receiving mold 22.

[0029] The output shaft of the second reduction motor 413 is coaxially connected to the brush main shaft 405 via a coupling to drive the brush main shaft 405 and the upper skewer brush 408 on it to rotate. The rotation direction of the upper skewer brush 408 is opposite to the rotation direction of the upper skewer roller 407. It is used to prevent the upper skewer roller 407 from carrying out too many bamboo skewers and to enable the bamboo skewers to enter the groove of the upper skewer roller 407 better.

[0030] An arc-shaped limiting plate 409 is set on the side of the upper skewer roller 407 away from the guide plate 402, and extends along the outer side of the circumferential surface of the upper skewer roller 407 to the space between the upper skewer roller 407 and the first chain plate type transport mechanism 21. The limiting plate 409 cooperates with the circumferential surface of the upper skewer roller 407 to prevent the bamboo skewer from falling off during the rotation on the upper skewer roller 407, and also to make the bamboo skewer fall more accurately into the receiving mold 22, thereby reducing the waste rate.

[0031] The skewering mechanism 5 is located above the middle of the skewer feeding mechanism 2. It pushes the bamboo skewers on the skewer feeding mechanism 2 to insert into the duck intestines. The skewering mechanism 5 includes a top plate 51, a piston cylinder 52, a sleeve plate 53, and multiple sliding shafts 54. The sleeve plate 53 is located above the middle of the skewer feeding mechanism 2 and the feeding end of the intestine feeding mechanism 3. The multiple sliding shafts 54 are vertically located at the top of the frame 1 and are slidably connected to the sleeve plate 53. The top plate 51 is located at the top of the multiple sliding shafts 54. The piston cylinder 52 is located between the top plate 51 and the sleeve plate 53, and its piston rod is downward and connected to the top of the sleeve plate 53.

[0032] Specifically, the sleeve 53 covers the upper part of the middle of the first chain conveyor 21 and extends to the upper part of the unloading end of the second chain conveyor 31.

[0033] In this embodiment, the number of sliding shafts 54 is preferably four, and they are arranged in a rectangular array on both sides of the middle of the first chain plate type transport mechanism 21. The sleeve plate 53 is slidably connected to the four sliding shafts 54 through a sliding sleeve, so that the sleeve plate 53 can move along the sliding shafts 54.

[0034] In this embodiment, the piston cylinder 52 is preferably a pneumatic cylinder, which is installed at the bottom end of the base plate 51 fixed to the top of the sliding shaft 54, and its piston rod is connected to the top end of the sleeve plate 53, so that the sleeve plate 53 can be moved up and down by the piston rod.

[0035] The bottom end of the sleeve plate 53 is provided with a first linear drive component 55, and the slider of the first linear drive component 55 is provided with a pusher component 56 for pushing the bamboo skewer towards and inserting it into the duck intestine.

[0036] Specifically, the first linear drive component 55 can drive the pusher component 56 to move closer to or further away from the sausage supply mechanism 3. When the sleeve plate 53 moves downward to make the pusher component 56 contact the receiving mold 22, the first linear drive component 55 drives the pusher component 56 to move closer to the sausage supply mechanism 3, thereby pushing the bamboo stick on the receiving mold 22 toward the sausage supply mechanism 3 and inserting it into the duck intestine. After the bamboo stick is inserted into the duck intestine, the sleeve plate 53 moves upward to make the pusher component 56 move away from the receiving mold 22, and the first linear drive component 55 drives the pusher component 56 to move away from the sausage supply mechanism 3 (reset).

[0037] The cutting mechanism 6 is located above the feeding end of the sausage feeding mechanism 3. It cuts the duck intestines transported on the sausage feeding mechanism 3. The cutting mechanism 6 includes a connecting plate 61 and a second linear drive assembly 62. The connecting plate 61 is located at the bottom end of the sleeve plate 53 above the feeding end of the sausage feeding mechanism 3. The second linear drive assembly 62 is located on the side of the connecting plate 61 near the pusher assembly 56, and its slider is provided with a cutter 63. The bottom end of the connecting plate 61 is provided with a forming upper mold 64 that is adapted to the forming lower mold 32.

[0038] Specifically, the second linear drive assembly 62 is mounted on the sleeve plate 53 via the connecting plate 61 and is located above the discharge end of the second chain plate conveyor mechanism 31. A replaceable cutter 63 is mounted on the slider of the second linear drive assembly 62. The blade of the cutter 63 is set at an angle downward to facilitate cutting the duck intestines.

[0039] When the sleeve plate 53 moves downward to make the pusher assembly 56 contact the receiving mold 22, the cutter 63 is located at the intestinal cutting groove between the two forming lower molds 32. At the same time, the second linear drive assembly 62 drives the cutter 63 on the slider to move from one end of the second chain plate transport mechanism 31 to the other end. In this process, the duck intestine in the forming lower mold 32 is cut off. After that, the sleeve plate 53 moves upward and the cutter 63 is reset.

[0040] Example 2: like Figure 4 , 7 As shown, the surface of the bamboo skewer receiving mold 22 has multiple first horizontal grooves 23 for accommodating bamboo skewers, first vertical grooves 24 adapted to the bamboo skewer feeding roller 407, and two second vertical grooves 25.

[0041] Specifically, the width of the skewer mold 22 and the length of its first horizontal groove 23 are adapted to the length of the bamboo skewer.

[0042] The first horizontal groove 23 is used to accommodate bamboo skewers. Its V-shaped groove can prevent the bamboo skewers from wobbling in the first horizontal groove 23.

[0043] A receiving mold 22 has 3-8 first horizontal grooves 23, preferably 5 first horizontal grooves 23 in this embodiment.

[0044] The first longitudinal groove 24 is located in the middle of the skewer receiving mold 22. It provides space for installing the limiting plate 409 to prevent the limiting plate 409 from colliding with the top of the skewer receiving mold 22. It also allows the limiting plate 409 to be closer to the bottom of the first transverse groove 23, thereby preventing the bamboo skewer from bouncing when it falls and allowing the bamboo skewer to fall more stably into the first transverse groove 23.

[0045] Example 3: like Figure 4 , 6 As shown, the first chain plate type transport mechanism 21 has supports 26 at both ends that are connected to its side walls, and two first guide tubes 27 that are fixedly connected to the two supports 26 are provided in the two second longitudinal grooves 25.

[0046] Specifically, the two first guide tubes 27 installed at the bottom of the support 26 are located at the top of the two second longitudinal grooves 25 respectively, and have a gap with the bottom of the second longitudinal grooves 25, allowing the bamboo skewer to pass through the gap, thereby limiting the bamboo skewer during transportation and preventing the bamboo skewer from tilting up during the subsequent skewering process, which would lead to skewering failure.

[0047] Two first guide tubes 27 extend from between the upper tagging mechanism 4 and the threading mechanism 5 to the outside of the unloading end of the first chain plate type transport mechanism 21.

[0048] The first guide tube 27 is preferably a stainless steel round tube.

[0049] Example 4: like Figure 4 , 6 As shown, a second guide tube 28 is provided in a second longitudinal groove 25 near the first longitudinal groove 24. The second guide tube 28 is U-shaped, with one end located below a first guide tube 27 and the other end fixed to the side wall of the first chain plate transport mechanism 21 near the sausage supply mechanism 3. A discharge receiving plate 29 is provided on the side wall.

[0050] Specifically, the straight sections at both ends of the U-shape of the second guide tube 28 can support the duck intestine skewers, while the first guide tube 27, located in a second longitudinal groove 25 away from the first longitudinal groove 24, is positioned above the second guide tube 28, thus forming a stable limiting structure for the duck intestine skewers. When the duck intestine skewers are being fed, the bamboo skewers are limited by the second guide tube 28 and the first guide tube 27, and the bamboo skewers of the duck intestine skewers are moved by the moving skewer receiving mold 22 to complete the feeding process.

[0051] The second guide tube 28 extends from the side of the threading mechanism 5 away from the loading mechanism 4 to the outside of the unloading end of the first chain plate transport mechanism 21.

[0052] The second guide tube 28 is preferably a stainless steel round tube.

[0053] The discharge plate 29 is used to temporarily place the duck intestine skewers being fed.

[0054] Example 5: like Figure 1 , 8 As shown, the upper forming mold 64 and the lower forming mold 32 are provided with multiple second transverse grooves 7 for accommodating duck intestines. The second transverse grooves 7 are adapted to the first transverse grooves 23. The two side walls of the second chain plate type transport mechanism 31 are provided with loading plates 33.

[0055] Specifically, the number of second horizontal grooves 7 on the upper forming mold 64 and the lower forming mold 32 are the same as the number of first horizontal grooves 23 on the tasseling mold 22, the same groove width, and the same spacing. The length of the second horizontal groove 7 is the same as the required length of each section of duck intestine.

[0056] The second transverse groove 7 on the lower forming mold 32 and the second transverse groove 7 on the upper forming mold 64 are staggered so that the second transverse groove 7 of the upper forming mold 64 can press down on the duck intestine inside the second transverse groove 7 of the lower forming mold 32.

[0057] The loading plate 33 is used to place and unfold the duck intestines.

[0058] The top of the discharge end of both sides of the second chain plate type transport mechanism 31 is also provided with a lower mold positioning plate 34, which is used for positioning the forming lower mold 32.

[0059] Example 6: like Figure 4 , 6 As shown, the card-adding mechanism 4 also includes a card-picking assembly 420, which is located at the bottom of the guide plate 402. The card-picking assembly 420 includes a first reduction motor 421, a cam 422, a connecting rod 423, and a card-picking base 424. The first reduction motor 421 is mounted on the bottom of the guide plate 402 via a fixed seat, and its output shaft is horizontally arranged. Each mounting plate 401 has a second linear guide rail 425 on its inner side below the guide plate 402. The two ends of the card-picking base 424 are slidably connected to the two second linear guide rails 425 respectively, and its top end is provided with at least two card-picking pieces 426. The cam 422 is fixedly connected to the end of the output shaft of the first reduction motor 421. One end of the connecting rod 423 is rotatably connected to the cam 422, and the other end is rotatably connected to the connecting piece of the card-picking base 424. The guide plate 402 has the same number of through slots as the card-picking pieces 426, so that the card-picking pieces 426 can pass through and move within them.

[0060] Specifically, the first geared motor 421 is a small geared motor (6ys01-18) using existing technology. Its output shaft is rotatably connected to a cam 422, which, when rotating, drives a paddle base 424 to move along a second linear guide rail 425 mounted on the inner side of two mounting plates 401 via a connecting rod 423. A paddle 426 at the top of the paddle base 424 passes through a slot on the guide plate 402 and can reciprocate within the slot. The reciprocating paddle 426 can move the bamboo skewers on the guide plate 402, thereby preventing the bamboo skewers from becoming clogged and from crossing over.

[0061] The preferred arrangement of the pick 426 is two intervals.

[0062] Example 7: like Figure 4 , 6 As shown, two mounting plates 401 are fixed on the side plates on both sides of the first chain plate transport mechanism 21, and multiple slots 411 arranged in a ring array are provided in the middle of the circumferential surface of the upper roller 407. Limiting disks 412 are coaxially provided on both sides of the brush main shaft 405.

[0063] Specifically, the width of the slot 411 is adapted to the diameter of the bamboo skewer, and it is used to place the bamboo skewer in it and drive the bamboo skewer to rotate when the skewer roller 407 rotates. The spacing between each slot 411 is adapted to the distance of the first horizontal groove 23 on the skewer receiving mold 22, so that the bamboo skewer on each set of slots 411 can continuously fall into the first horizontal groove 23.

[0064] The limiting discs 412 on both sides of the brush spindle 405 are spaced apart, and the distance between them is adapted to the width of the upper skewer roller 407. The circumferential surfaces of the two limiting discs 412 are in contact with the circumferential surface of the upper skewer roller 407 so that the bamboo skewers can be accurately placed in the slots 411 and the bamboo skewers in the slots 411 are limited.

[0065] Example 8: As shown in 5, 6, and 8, the pusher assembly 56 includes a fixing plate 561, which is horizontally disposed at the bottom end of the slider of the first linear drive assembly 55. The bottom end of the fixing plate 561 away from the intestine supply mechanism 3 is provided with a pusher plate 562, and the bottom end near the intestine supply mechanism 3 is provided with a pressing plate 563. The bottom end of the pusher plate 562 has pusher teeth 564 that are adapted to the first transverse groove 23, and the bottom end of the pressing plate 563 has pressing teeth 565 that are adapted to the first transverse groove 23.

[0066] Specifically, the first linear drive component 55 drives the fixed plate 561 to reciprocate, and can drive the push plate 562 and the pressure plate 563 set at its bottom end to move toward the intestine supply mechanism 3.

[0067] When the piston rod 52 drives the sleeve plate 53 to descend and causes the pressing teeth 565 of the pressing plate 563 to extend into the corresponding first transverse groove 23, thus restricting the vertical movement of the bamboo skewer within the first transverse groove 23 (without fixing the bamboo skewer), the pushing teeth 564 of the pushing plate 562 also extend into the first transverse groove 23 and are located at the tail end of the bamboo skewer. The first linear drive assembly 55 drives the pushing plate 562 and the pressing plate 563 to move towards the sausage feeding mechanism 3. The pushing teeth 564 push the corresponding bamboo skewer (pressing against the tail end of the bamboo skewer) into the lower forming mold 32 and insert it into the duck intestine to complete the skewering operation. After skewering is completed, the sleeve plate 53, the pushing plate 562, and the pressing plate 563 reset.

[0068] The first linear drive assembly 55 can be a drive chain group or a linear rodless cylinder. In this embodiment, the first linear drive assembly 55 is preferably a drive chain group composed of two drive chains. The chain is driven to rotate on the sprocket by a servo motor (60ms1-400w) equipped with a reducer (rv40-56), thereby driving the fixed plate 561, which is fixedly connected to the slider on the sprocket, to reciprocate. A linear guide rail is also provided on the inner side of the ring formed by each chain. The slider in the drive chain group is slidably connected to the linear guide rail, thereby increasing the stability of the slider when moving.

[0069] Example 9: like Figure 8 As shown, the first linear drive assembly 55 has a skewer plate 566 fixed at one end near the cutting mechanism 6 via an L-shaped mounting base. The bottom end of the skewer plate 566 has a skewer groove 567 that is adapted to the first horizontal groove 23 to prevent the bamboo skewer from tilting or shifting when it moves in the first horizontal groove 23.

[0070] Example 9: like Figure 5 , 9 As shown, the upper forming mold 64 has a through groove 65 that is wider than the lower forming mold 32, and the cutter 63 extends through the through groove 65 to the bottom of the connecting plate 61.

[0071] Specifically, the pass groove 65 is used for the reciprocating motion of the cutter 63.

[0072] Example 10: As shown in 6 and 9, it also includes a bamboo skewer flip plate 8. The bamboo skewer flip plate 8 is rotatably disposed on the side plate of the first chain plate transport mechanism 21 near the second chain plate transport mechanism 31 and is located between the first chain plate transport mechanism 21 and the second chain plate transport mechanism 31, so as to lift the bamboo skewer that has been skewered and separate the bamboo skewer with the duck intestine end from the forming lower mold 32. The L-shaped mounting base has a connecting shaft 9 on one side, and the connecting shaft 9 is connected to one side of the bamboo skewer flip plate 8 through an elastic connector 10.

[0073] Specifically, the L-shaped mounting base rises and falls with the lifting of the sleeve plate 53. When the duck intestines are skewered, the L-shaped mounting base descends and drives the bamboo skewer flip plate 8 to rotate downward through the elastic connector 10 so as not to block the passage of the bamboo skewer. After the duck intestines are skewered, the L-shaped mounting base rises and drives the bamboo skewer flip plate 8 to rotate upward through the elastic connector 10, thereby lifting the end of the bamboo skewer with duck intestines, so that the end of the duck intestine with duck intestines is separated from the second transverse groove 7 of the forming lower mold 32. After being lifted, the duck intestine skewer is moved to the lower end of the material through the first chain plate type transport mechanism 21 and the receiving mold 22, thereby driving the duck intestine skewer to leave the forming lower mold until the material is unloaded.

[0074] The elastic connector 10 is preferably a spring.

[0075] Example 11: As shown in Figure 5, a baffle plate 11 and a duck intestine waste tray 12 are provided on the side wall of the first chain plate transport mechanism 21 near the second chain plate transport mechanism 31. The duck intestine waste tray 12 is located on the outside of the side wall of the first chain plate transport mechanism 21 and below the baffle plate 11. The baffle plate 11 is embedded in the side wall of the first chain plate transport mechanism 21 and corresponds to the discharge end position of the second chain plate transport mechanism 31 so as to guide the duck intestine waste into the duck intestine waste tray 12. A bamboo skewer waste tray 13 is provided at the bottom of the first chain plate transport mechanism 21.

[0076] Specifically, if the duck intestines in the second transverse groove 7 of the forming mold 32 are not successfully threaded, they will fall as the forming mold 32 rotates to the bottom of the second chain plate transport mechanism 31, and the duck intestine waste can be guided into the duck intestine waste tray 12 by the baffle plate 11.

[0077] Bamboo skewer waste tray 13 is used to collect bamboo skewers that have not been properly skewered.

[0078] Example 12: The first chain plate transport mechanism 21 is tilted 2-5° to the side away from the second chain plate transport mechanism 31. The second chain plate transport mechanism 31 is set on the frame 1 with a lifting angle of 2-5°. The tilt angle of the first chain plate transport mechanism 21 is the same as the lifting angle of the second chain plate transport mechanism 31, so as to facilitate the selection and skewering of duck intestines.

[0079] Example 12: The frame 1 has an electrical box for power supply inside. The bottom of the frame 1 is equipped with multiple casters. The top of the frame 1 is equipped with a control panel 14. The control panel 14 is electrically connected to the electronic components in a duck intestine skewering device and controls the electronic components through the controller therein.

[0080] Example 14: The top plate 51 is hinged with transparent or semi-transparent protective plates on its four sides to protect the threading mechanism 5 and facilitate observation. The protective plates can be made of glass or acrylic.

[0081] Example 15: The duck intestine skewering device in Examples 1-14 can also skewer other types of intestines, such as chicken intestines and goose intestines, after the size of its components is adjusted.

[0082] The duck intestine skewering device of this utility model has a duck intestine skewer production capacity of 8,000-10,000 skewers / hour, which greatly improves the efficiency of duck intestine skewering.

[0083] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
