Description

Technical Field

[0001] The utility model belongs to the technical field of poultry gizzard processing, and more specifically relates to a poultry gizzard peeling machine. Background Art

[0002] During the processing and production of poultry products, gizzard cleaning is mainly divided into three steps: cutting, cleaning, and removing the yellow skin. The yellow skin removal step involves peeling off the yellow skin layer on the inner wall of the cut gizzard, which wraps the grain. The traditional method of removing the yellow skin is to manually scrape the yellow skin by a large number of workers. This method is not only inefficient but also greatly increases labor costs. Therefore, gizzard peeling machines for removing the yellow skin of poultry gizzards have appeared on the market.

[0003] At present, most of the existing gizzard stripping machines use a set of gizzard stripping rollers with interlocking threads to rotate relative to each other to bite the yellow skin and separate it from the inner wall of the gizzard. The operation method of the gizzard stripping machine is generally to manually place the gizzard with yellow skin on the gizzard stripping rollers, and then use an electric motor to drive the gizzard stripping rollers to rotate relative to each other, so that the meshing part between the gizzard stripping rollers bites the junction between the gizzard and the yellow skin, and uses the squeezing force of the opposite rotation to squeeze and tear off the yellow skin. However, during the operation of the gizzard stripping machine, the gizzard needs to be manually fed to the gizzard stripping rollers, and the rotating gizzard stripping rollers may clamp the gizzard if not careful. The gizzards are not easily peeled off or completely peeled off due to the lack of manual labor, and there is a great safety hazard. In addition, since there is no structure for limiting the position of the gizzards and adjusting the direction of the gizzards, during the gizzard peeling process, it is easy for the inner side of the gizzard with the yellow skin to face upwards and the outer side of the gizzard to contact the gizzard peeling roller, that is, the gizzard is placed upside down, or the yellow skin is not fully in contact with the gizzard peeling roller, or multiple gizzards are stacked, resulting in the yellow skin of some gizzards not being peeled off or not being completely peeled off. Subsequently, these gizzards often need to be manually pressed one by one onto the gizzard peeling roller for re-peeling, resulting in poor gizzard peeling effect, low gizzard peeling efficiency and low safety.

[0028] In order to explain the technical content, purpose and effect of the present invention in detail, the following is a description of the embodiments and the accompanying drawings. It should be noted that the words "upper" and "lower" used in the following description refer to the attached Figure 1 and Figure 4 In the directions, the words "bottom" and "top" refer to the Figure 1 and Figure 4 The direction towards the geometric center of a specific component.

[0029] The key concept of the present invention is that: the conveying device 3, the chute 13 and the feeding tray 5 are used to transport the inverted gizzards over a long distance and in an orderly manner, thereby increasing the distance between the front and rear gizzards, avoiding the problem of gizzard stacking and the need for manual screening of the gizzards to be peeled off again, thereby improving the gizzard peeling effect and efficiency; the platform 12 and the straight feed port 10 are used to decelerate the gizzards while ensuring that the inverted gizzards fall directly into the gizzard peeling bin 2 without hindrance under the action of inertia, thereby ensuring the accuracy and stability of the gizzards entering the bin; the guide column 14 plays a role in guiding the conveying device 3, the chute 13 and the platform 12 The feeding tray 5 and the chute 13 also reduce the impact of the gizzards falling onto the gizzard stripping roller 4, thereby preventing the gizzards from rebounding and turning over when they fall onto the gizzard stripping roller 4; the arc-shaped baffle 7 and the limit block 6 play the role of positioning the gizzards on the feeding tray 5; the gizzard discharge hole 8 and the driving device are used to automatically turn over the inverted gizzards and accurately transport them to the front end of the gizzard stripping roller 4; several groups of gizzard stripping rollers 4, the kneading mechanism and the driving device are used to simultaneously reciprocate and knead the outer side surface a of the gizzards and peel off the yellow skin d, ensuring that the yellow skin d is in full contact with the gizzard stripping roller 4, thereby automatically and completely peeling off the yellow skin d of the gizzards;

[0030] The utility model automatically transports, positions, and kneads and peels multiple rows of poultry gizzards in an orderly manner, avoids direct contact between human hands and the gizzard peeling roller 4 and the stacking of poultry gizzards, ensures that the poultry gizzards are kept upright during the peeling process and that the yellow skin d is in full contact with the gizzard peeling roller 4, and has the advantages of good gizzard peeling effect, high gizzard peeling efficiency and high safety.

[0031] Please refer to Figures 1 to 10 As shown, a poultry gizzard peeling machine includes a workbench 1, on which a gizzard peeling bin 2 and a conveying device 3 for conveying a plurality of inverted gizzards are sequentially installed from top to bottom. Several groups of gizzard peeling rollers 4 and several feeding trays 5 are rotatably connected in the gizzard peeling bin 2. Each feeding tray 5 is located directly above the front end of a group of gizzard peeling rollers 4. A kneading mechanism for kneading the outer side surface a of the gizzard is mounted above the gizzard peeling rollers 4. The gizzard peeling bin 2 is equipped with a driving device for driving the gizzard peeling rollers 4 and the feeding tray 5 to rotate. Several limit blocks 6 for placing the middle recess c of the outer side surface of the gizzard are evenly distributed along the circumference on the outer side of the feeding tray 5. An arc-shaped baffle 7 is installed in the gizzard stripping bin 2 to prevent the gizzards from falling from the feeding tray 5. A gizzard discharge hole 8 is provided at the bottom of the arc-shaped baffle 7, which is located directly below the feeding tray 5; a discharge port 9 and several straight feed ports 10 located directly above the feeding tray 5 are respectively provided on both sides of the gizzard stripping bin 2, and an upper baffle 11 and a platform 12 are respectively provided on the opposite sides of the straight feed port 10. A chute 13 with a closed upper end face is connected between the output end of the conveying device 3 and the platform 12. Several guide columns 14 are mounted on the chute 13, the conveying device 3 and the platform 12 for placing the middle recess c on the outer side of the gizzard.

[0032] From the above description, it can be seen that when it is necessary to peel the gizzards after the poultry gizzards are cut in half, first, a plurality of poultry gizzards to be peeled are placed upside down on the conveying device 3 in sequence through the conveying device 3 and the guide column 14, and the guide column 14 set up on the conveying device 3 is used to support the middle depression of the outer surface of the poultry gizzards, so that the poultry gizzards are kept in an upside-down state to avoid the poultry gizzards from turning over, thereby playing the role of preliminary positioning and preliminary automatic feeding and conveying of the poultry gizzards to be peeled; after the conveying device 3 conveys the poultry gizzards to be peeled to the end of the conveying device 3, the poultry gizzards are placed upside down through the chute 13, the straight feed port 10, the platform 12 and the guide column 14 are used to support the poultry gizzards. The guide column 14, because the upper end surface of the chute 13 is closed, under the action of gravity, and the limiting effect of the upper end surface of the chute 13 and the guide column 14 on the upper, lower and inner and outer sides of the gizzards, ensures that the inverted gizzards slide down from the end of the conveying device 3 through the chute 13 to the platform 12 in a directed manner. Under the buffering effect of the platform 12, the gizzards are prevented from moving and colliding with the upper baffle 11. After being decelerated by the platform 12, the gizzards are in an inverted state under the action of inertia and fall unhindered through the straight feed port 10 into the gizzard stripping bin 2, thereby playing the role of secondary positioning and secondary automatic feeding and conveying of the gizzards to be peeled;

[0033] Then, through the feeding tray 5, the arc-shaped baffle 7, the poultry gizzard feeding hole 8, the limiting block 6 and the driving device, the inverted poultry gizzards fall to the top of the feeding tray 5 without hindrance through the straight feeding port 10. The limiting block 6 on the top of the feeding tray 5 is used to support the middle depression c on the outer side of the inverted poultry gizzards. At this time, the outer side a of the poultry gizzards contacts the side of the feeding tray 5, and the yellow skin d of the poultry gizzards faces the arc-shaped baffle 7. Then, the external controller is used to control the poultry gizzards to be the same as the feeding tray 5. The control driving device drives the feeding tray 5 to rotate downward, thereby driving the gizzards on the feeding tray 5 to rotate downward together. Under the obstruction of the arc baffle 7, the inner and outer sides of the gizzards are limited between the arc baffle 7 and the circumferential side of the feeding tray 5 to prevent the gizzards from falling from the feeding tray 5. Until the gizzards are transferred to the middle and upper part of a group of gizzard stripping rollers 4, the gizzards lose the supporting force of the arc baffle 7. Under the action of gravity, the gizzards fall vertically from the gizzard feeding hole 8 in an upright state to the middle position of the front end of a group of gizzard stripping rollers 4, which plays the role of limiting the gizzards again and automatically turning over the inverted gizzards and conveying them to the front end of the gizzard stripping rollers 4; finally, through several groups of gizzard stripping rollers 4, kneading mechanisms and driving devices, the external controller controls the driving device to drive the gizzard stripping rollers 4 to rotate and the kneading mechanism to start. The outer side a is kneaded and pressed back and forth, simulating the reciprocating kneading of the outer side a of the gizzard by a human hand, so that the yellow skin d on the inner side b of the gizzard is fully in contact with the gizzard peeling roller 4, so that the same set of relatively rotating gizzard peeling rollers 4 peels off the yellow skin d of the gizzard. After the yellow skin d is peeled off, the gizzard moves to the end of the gizzard peeling roller 4 under the action of the gizzard peeling roller 4, and falls to the discharge port 9 through the end of the gizzard peeling roller 4, thereby achieving the effect of automatically and completely peeling off the yellow skin d of the gizzard;

[0034] By providing the conveying device 3, the feeding tray 5 and the chute 13, the distance between the front and rear gizzards is increased, thereby avoiding the problem of the yellow skin d of some gizzards not being peeled off or not being completely peeled off due to the accumulation of gizzards, and eliminating the need for manual screening and re-peeling of the discharged gizzards at the discharge port 9, thereby improving the gizzard peeling effect and efficiency; the feeding tray 5 and the chute 13 also reduce the impact force of the gizzards falling from the conveying device 3 or the feeding port to the gizzard peeling roller 4. The gizzards are prevented from falling straight onto the gizzard peeling roller 4 and rebounding to turn over or deviate, and the gizzards are ensured to be placed right on the gizzard peeling roller 4. The purpose of adopting the inverted conveying method is, firstly, to facilitate positioning and conveying, and secondly, the yellow skin d is upwardly facing to facilitate identification of whether the gizzards are placed in the wrong direction. The direct contact between human hands and the gizzard peeling roller 4 and the stacking of gizzards are avoided as a whole, and the gizzards are ensured to be kept right during the peeling process and the yellow skin d is in full contact with the gizzard peeling roller 4, which has the advantages of good gizzard peeling effect, high gizzard peeling efficiency and high safety.

[0035] Furthermore, the kneading mechanism includes several kneading rollers 15 and a first motor 16 for driving the kneading rollers 15 to rotate back and forth. Each kneading roller 15 is located directly above a group of gizzard peeling rollers 4. The outer peripheral side surfaces of the kneading rollers 15 are evenly connected with several groups of kneading blocks 17 for kneading the outer side surfaces a of the gizzards. The upper end of the gizzard peeling bin 2 is fixedly connected with a mounting plate 18 located between the feeding tray 5 and the kneading rollers 15. One side of the mounting plate 18 is rotatably connected to one end of the kneading rollers 15. A first synchronous transmission mechanism 19 is connected between the other ends of the several kneading rollers 15. The other end of the kneading rollers 15 is rotatably connected to the inner wall of the gizzard peeling bin 2 near the rear end of the gizzard peeling roller 4; the first motor 16 is installed outside the gizzard peeling bin 2, and a second synchronous transmission mechanism 48 is connected between the driving end and the other end of one of the kneading rollers 15.

[0036] From the above description, it can be seen that after the upright poultry gizzard falls to the middle position of the front end of a group of gizzard peeling rollers 4, the external controller controls the first motor 16 to start, and the driving end of the first motor 16 drives one of the kneading rollers 15 to rotate back and forth with a small amplitude. Under the action of the first synchronous transmission mechanism 19, the kneading roller 15 drives the other kneading rollers 15 to rotate back and forth synchronously with the amplitude, and then drives the kneading block 17 to knead the outer side surface of the poultry gizzard back and forth, so as to simulate the effect of human hands kneading the outer side surface a of the poultry gizzard back and forth, so as to facilitate the yellow skin d on the inner side surface b of the poultry gizzard to fully contact with the gizzard peeling roller 4, to ensure that the yellow skin d of the poultry gizzard is completely peeled off, and to further improve the overall gizzard peeling effect and gizzard peeling efficiency.

[0037] Furthermore, several groups of adjustment plates 20 for adjusting the positions of the gizzards on both sides are provided between the kneading roller 15 and the feed tray 5. Each group of adjustment plates 20 is provided with two adjustment plates 20. Each adjustment plate 20 is located above the front end of the gizzard peeling roller 4. An adjustment channel 21 for the gizzards to pass through is formed between the adjustment plates 20 in the same group. The adjustment channel 21 is gradually expanded in the direction approaching the feed tray 5. The top of the adjustment plate 20 is fixedly connected to the bottom of the mounting plate 18.

[0038] From the above description, it can be seen that through the adjustment plate 20 and the adjustment channel 21 which is gradually expanded toward the feeding tray 5, when the upright poultry gizzards fall in the middle position of the front end of a group of gizzard peeling rollers 4, under the action of the gizzard peeling rollers 4, the poultry gizzards first enter the adjustment channel 21, and the adjustment plate 20 above the group of gizzard peeling rollers 4 is used to gradually adjust and limit the two sides of the poultry gizzards to avoid the two sides of the poultry gizzards deviating too much from the group of gizzard peeling rollers 4, thereby causing the poultry gizzards to fall from the gizzard peeling rollers 4 or the yellow skin d to be insufficiently in contact with the gizzard peeling rollers 4, thereby further improving the overall gizzard peeling effect and efficiency.

[0039] Furthermore, the arc-shaped baffle 7 includes an arc-shaped main board 22, a connecting seat 23 and two arc-shaped side panels 24. The arc-shaped main board 22 is sleeved on the outer circumferential side of the feed tray 5. The two arc-shaped side panels 24 are respectively connected to both sides of the arc-shaped main board 22. One of the arc-shaped side panels 24 is detachably connected to the inner wall of the gizzard peeling bin 2 through the connecting seat 23. The top of the arc-shaped main board 22 is fixedly connected to one side of the bottom of the straight feed port 10, and the other three sides of the bottom of the straight feed port 10 are connected to the lower baffle 25.

[0040] From the above description, it can be seen that in the process of the feeding tray 5 driving the poultry gizzard to turn downward 180°, the arc-shaped main board 22 is used to support the yellow skin d of the poultry gizzard, and the inner and outer sides of the poultry gizzard are limited between the arc-shaped main board 22 and the circumferential side of the feeding tray 5 to prevent the poultry gizzard from falling from the feeding tray 5, thereby further limiting and supporting the poultry gizzard on the feeding tray 5; the arc-shaped side plates 24 are used to limit the front and rear sides of the poultry gizzard to prevent the poultry gizzard from falling from the feeding tray The two end surfaces of the plate 5 fall off, which plays the role of re-limiting the gizzards on the feeding plate 5. The arc-shaped baffle 7 ensures that the state of the gizzards remains unchanged as the feeding plate 5 rotates. The lower baffle 25 is used to limit the gizzards that initially fall from the straight feeding port 10 to the feeding plate 5, ensuring that the gizzards that fall from the straight feeding port 10 can accurately fall to the top limit block 6 of the feeding plate 5, thereby further improving the overall gizzard peeling effect and efficiency.

[0041] Furthermore, the arc-shaped main board 22 is arranged cocentrically with the feeding tray 5 , and a scraping blade 26 and a frosted surface 27 for preliminarily scraping off the yellow skin d of the gizzards are embedded on the inner side surface of the arc-shaped main board 22 close to the feeding tray 5 .

[0042] From the above description, it can be seen that in the process of the feeding tray 5 driving the poultry gizzards to turn downward 180°, the scraper blade 26 and the frosted surface 27 are used to perform preliminary slight friction scraping on the yellow skin d of the poultry gizzards on the feeding tray 5, thereby playing the role of preliminary removal of the yellow skin d of the poultry gizzards.

[0043] Furthermore, the driving device includes a second motor 28 and several third motors 29, both of which are installed on the outside of the gizzard peeling bin 2. The driving end of the second motor 28 is connected to the main sprocket 30, and one end of the gizzard peeling roller 4 is connected to a transmission tooth 31. Adjacent transmission teeth 31 are engaged with each other. One end of the middle gizzard peeling roller 4 is connected to a secondary sprocket 32, and a transmission chain 33 is connected between the main sprocket 30 and the secondary sprocket 32. One end of the feeding tray 5 is connected to a rotating shaft 34; one end of the rotating shaft 34 is rotatably connected to the inner wall of the gizzard peeling bin 2, and is fixedly connected to the driving end of the third motor 29. A lower photoelectric switch 36 is installed at the upper end of the straight feed port 10.

[0044] As can be seen from the above description, when gizzards need to be stripped, the second motor 28 is started through the second motor 28, the main sprocket 30, the secondary sprocket 32 ​​and the transmission gear 31. The driving end of the second motor 28 rotates, driving the main sprocket 30 to rotate, and the secondary sprocket 32 ​​is driven to rotate through the transmission chain 33, thereby driving the gizzard stripping roller 4 with one end connected to the secondary sprocket 32 ​​to rotate, and the other gizzard stripping rollers 4 are driven to rotate by the engagement of the transmission gear 31, thereby realizing the function of automatically driving the gizzard stripping roller 4 to rotate; when the poultry gizzards fall to the feeding tray 5 through the straight feeding port 10, through the lower photoelectric switch 36, the rotating shaft 34 and the third motor 29, first, the lower photoelectric switch corresponding to the straight feeding port 10 is turned on. The switch 36 first transmits the information that the gizzards have been detected entering the straight feed port 10 to the external controller, and the external controller (not shown in the figure, the same as in the full text) controls the corresponding third motor 29 to rotate. The driving end of the third motor 29 rotates, driving the rotating shaft 34 and the feed tray 5 to rotate, thereby driving the gizzards on the feed tray 5 to rotate toward the front end of the gizzard peeling roller 4, until the gizzards inverted from the straight feed port 10 are rotated through the feed tray 5 to be positioned upright above a group of gizzard peeling rollers 4, and then fall through the gizzard discharge hole 8 to the middle of a group of gizzard peeling rollers 4, thereby automatically driving the feed tray 5 to flip the inverted gizzards 180° and transport them to the front end of the gizzard peeling roller 4.

[0045] Furthermore, the conveying device 3 is evenly provided with a plurality of groups of protrusions 37 for limiting the two sides of the bottom of the poultry gizzards. The protrusion groups 37 include protrusions 37 located on both sides of the guide column 14 respectively. The top of the chute 13 is provided with an arc portion 38. The arc portion 38 is provided with a clearance hole 39 for the protrusions 37 to pass through. A lower pressure plate 40 for pressing down the inner yellow skin d of the poultry gizzards is mounted above the platform 12 and the chute 13. The bottom of the lower pressure plate 40 is connected to a long plate 41 for limiting the two sides of the upper end of the poultry gizzards. The guide column 14 of the conveying device 3, the guide column 14 of the chute 13 and the guide column 14 of the platform 12 are integrally formed.

[0046] The gizzards are preferably placed on the conveying device 3 and the guide posts 14 on the conveying device 3 are preferably provided with a plurality of guide posts 14 on the conveying device 3 so as to prevent the gizzards from shaking during transportation and falling off the guide posts 14 on the conveying device 3, thereby further limiting the gizzards. The arc portion 38 facilitates the smooth transportation of the gizzards from the end of the conveying device 3 to the chute 13, thereby further ensuring the stability of the feeding and conveying of the inverted gizzards. The lower pressure plate 40 and the long plate 41 are used to limit the top and both sides of the gizzards on the platform 12 and the chute 13, thereby further improving the stability of the feeding and conveying of the gizzards, thereby preventing the inverted gizzards from turning over during transportation and affecting the smooth inversion of the gizzards into the straight feed port 10, thereby affecting the subsequent gizzards from being placed on the position of the gizzard stripping roller 4, thereby further ensuring the overall stripping effect and improving the stripping efficiency.

[0047] Furthermore, a color recognition device for detecting the color of the top of the gizzard is installed above the conveying device 3. The color recognition device includes an LED light 42, an industrial camera 43, an alarm 44, an upper photoelectric switch 45 for detecting the presence of gizzards, and a light shielding frame 46 arranged in an inverted U shape. The light shielding frame 46 is installed above the conveying device 3; each of the LED light 42 and the industrial camera 43 is provided with a group, and both are installed at the top of the light shielding frame 46. The industrial camera 43 is located directly above the guide column 14. The industrial camera 43 is electrically connected to an industrial computer, and the alarm 44 is electrically connected to the output signal of the industrial computer.

[0048] As can be seen from the above description, when the gizzards are conveyed to the color recognition device, through the upper photoelectric switch 45, the light shielding frame 46, the alarm 44 and the industrial camera 43, when the gizzards are conveyed by the conveying device 3 to the bottom of the light shielding frame 46, the upper photoelectric switch 45 will detect the color of the top surface of the gizzards and send the signal to the external controller. The external controller controls a group of industrial cameras 43 to start up, and uses the industrial cameras 43 to collect and identify the top image color of the gizzards in the light shielding frame 46. The industrial camera 43 sends the image information of the top surface of the gizzards to the industrial computer, which first compares and classifies the image with the preset picture. If it is detected that The gizzard on the conveying device 3 is in an upright position, that is, the yellow skin d on the inner side b of the gizzard is facing downward, the industrial computer controls the alarm 44 to sound, and manually or using an external manipulator to flip the upright gizzard 180 degrees and place it upside down on the conveying device 3, which plays a role in automatically identifying and detecting the color of the top of the gizzard and automatically detecting the placement direction of the gizzard on the conveying device 3; the light shielding frame 46 and the LED light 42 are used to illuminate the gizzard, and at the same time, avoid the influence of the changeable light in the external environment on the recognition accuracy of the gizzard color, thereby avoiding affecting the overall recognition and detection accuracy, thereby further improving the overall gizzard peeling effect and gizzard peeling efficiency.

[0049] Furthermore, the outer surface of the gizzard peeling roller 4 is provided with spiral patterns, and the spiral patterns of adjacent gizzard peeling rollers 4 are arranged in opposite directions. The end of the gizzard peeling roller 4 is provided with a pushing mechanism 47 for pushing the poultry gizzard after the yellow skin d is removed to the discharge port 9, and a collection box 35 is provided below the discharge port 9.

[0050] From the above description, it can be seen that the spiral pattern on the outer surface of the gizzard peeling roller 4 is used to peel off the yellow skin d of the gizzard. The adjacent gizzard peeling rollers 4 are provided with reverse spiral patterns to increase the friction during gizzard peeling, thereby achieving a better gizzard peeling effect. The gizzards after the yellow skin d is peeled are pushed to the discharge port 9 by the pushing mechanism 47 and the collection box 35. Under the action of gravity, the gizzards fall into the collection box 35 through the discharge port 9, thereby automatically discharging and collecting the gizzards after the yellow skin d is removed.
