Description

Technical Field

[0001] This utility model relates to the field of poultry processing technology, and in particular to an automatic poultry gizzard opening device and an automatic gizzard opening machine. Background Technology

[0002] Poultry gizzards, especially chicken and duck gizzards, are popular among consumers for their digestive and stomach-strengthening effects. Chicken gizzards, the inner lining of the gizzard in domestic chickens, are a digestive organ used for grinding food and are also a traditional Chinese medicine, showing significant effectiveness in treating indigestion and other ailments.

[0003] During the slaughtering and processing of poultry, the gizzards need to be opened to remove internal dirt and keratinous skin, facilitating subsequent processing. Various gizzard-opening machines are available on the market, and operators use these machines to open the gizzards. However, numerous problems arise during the opening process.

[0004] For semi-automatic gizzard-opening machines, the operator must hold the gizzards by hand and cut them one by one on the machine. While this method can achieve neat and uniform cuts and a high product qualification rate, the operation process is complex, the production efficiency is low, and there is a risk of injury due to improper operation.

[0005] For automatic gizzard opening machines, the operator places the gizzards onto a tray on a conveyor belt as required, and the tray delivers the gizzards to the cutting area. In the cutting area, a rotating cutting blade cuts the gizzards in half, guided and secured by fixing devices during the cutting process. This equipment improves production efficiency and reduces the risk of operator injury. However, in actual production, because the surface of the gizzards is slippery, it is often difficult to secure them completely, causing the gizzards to deviate from their intended position during cutting, resulting in a change in the cutting position and thus reducing the product qualification rate.

[0014] A guide rod, the bottom end of which passes through the straightening body and is connected to the frame, and a nut is threaded onto the guide rod, the nut being located above the straightening body;

[0015] A top spring is sleeved on the guide rod and abuts against the frame and the straightening body;

[0016] A compression spring is sleeved on the guide rod and abuts against the centering body and the nut.

[0017] Preferably, the straightening body is provided with two or four of the elastic drive components.

[0018] Preferably, the front end of the needle is provided with a rearward-extending and upward-sloping guide slope, which extends from front to back and is close to the blade of the rotary cutting blade.

[0026] An automatic gizzard opening machine, comprising the aforementioned automatic gizzard opening device for poultry;

[0027] A horizontally arranged gizzard conveying mechanism is installed on the frame. The gizzard conveying mechanism is located below the straightening groove and extends to the rear of the rotating cutter. The gizzard conveying mechanism adopts a gizzard conveying chain or a gizzard conveying belt. A gizzard tray is provided on the gizzard conveying chain or the gizzard conveying belt.

[0028] After adopting the above technical solution, the beneficial effects of this utility model are:

[0029] The poultry automatic gizzard-opening device of this application is used to be installed above the frame of an automatic gizzard-opening machine, and includes: an installation platform, an automatic uprighting and positioning mechanism, and an automatic cutting mechanism. The installation platform is located above the frame; the automatic uprighting and positioning mechanism includes: an uprighting body, an elastic drive component, and a guide pin; the bottom of the uprighting body has a longitudinally penetrating uprighting groove, and the rear of the uprighting body has a longitudinally extending blade-receiving slit that communicates with the uprighting groove; the elastic drive component passes vertically through the uprighting body, and its lower end is used to fix it to the frame; the guide pin is located behind the uprighting body, and its front end extends horizontally into the uprighting groove. When an external gizzard conveying mechanism transports the gizzard to the uprighting body, the gizzard first enters the uprighting groove, where the uprighting body uprights it and, in cooperation with the gizzard conveying mechanism, presses it down and fixes it, preventing it from moving around randomly in the uprighting groove. This results in neat and uniform cuts during subsequent cutting, improving the product qualification rate. As the gizzard conveying mechanism moves the gizzard backward, the guide needle first inserts into the gizzard's inner cavity. With the gizzard's continued movement, the guide needle supports the inner cavity. The guide needle works in conjunction with the outer support body to first fix the gizzard internally, preventing it from moving around before cutting. Secondly, it expands the gizzard's inner cavity, making it easier for the cutting blade to cut and achieve a neat and uniform cut.

[0030] The automatic cutting mechanism includes a vertically arranged rotary cutting blade, driven by a cutting power unit. The blade extends vertically into the straightening groove through a blade-receiving gap, and is positioned above the tip of the guide needle. As the gizzard continues to move backward, the rotary cutting blade cuts the upper part of the gizzard while the lower part remains connected, thus opening the gizzard. This replaces the traditional semi-automatic gizzard-opening machine, which requires manual cutting of each gizzard individually, reducing labor and production costs, improving production efficiency, and eliminating the risk of injury from improper operation.

[0031] Meanwhile, the automatic gizzard opening machine of this application includes an automatic uprighting and gizzard opening device for poultry. A horizontally arranged gizzard conveying mechanism is installed on the frame. The gizzard conveying mechanism is located below the uprighting groove and extends to the rear of the rotary cutting blade. The gizzard conveying mechanism adopts a gizzard conveying chain or a gizzard conveyor belt, and a gizzard tray is set on the gizzard conveying chain or gizzard conveyor belt. The gizzard conveying mechanism is used to transport gizzards. The gizzard conveying mechanism works in conjunction with the automatic uprighting and positioning mechanism and the automatic cutting mechanism to automatically transport, upright, fix, internally support, and cut the gizzards, achieving neat and uniform cuts, improving the product qualification rate. At the same time, it can replace the traditional method of manual hand cutting, reducing production costs, improving production efficiency, and also improving operational safety.

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0052] Example 1

[0053] like Figures 1 to 3 , Figure 11 As shown in the figure, this embodiment discloses an automatic uprighting and gizzard-opening device for poultry, used to open the gizzard 61. The gizzard 61 mainly refers to chicken gizzards, duck gizzards, and goose gizzards; this embodiment uses a chicken gizzard as an example.

[0054] The automatic gizzard-opening device for poultry is installed above the frame 1 of the automatic gizzard-opening machine and includes: a mounting platform 3, an automatic uprighting and positioning mechanism 2, and an automatic cutting mechanism 4.

[0055] The mounting platform 3 is located above the rack 1.

[0056] The automatic straightening and positioning mechanism 2 includes: a straightening body 21, an elastic drive assembly 22 for making the straightening body 21 float up and down, and a needle 41 for inserting into the gizzard 61; the straightening body 21 is located at the front of the mounting platform 3, the bottom of the straightening body 21 is recessed with a straightening groove 23 that runs longitudinally through it, and the rear of the straightening body 21 is provided with a longitudinally extending knife-receiving slot 24 that communicates with the straightening groove 23; the elastic drive assembly 22 is located outside the straightening groove 23 and passes through the straightening body 21 vertically, and the lower end of the elastic drive assembly 22 is used to fix it to the frame 1; the needle 41 is located behind the straightening body 21, the front end of the needle 41 extends horizontally into the straightening groove 23, and the upper end of the needle 41 is fixed to the bottom of the mounting platform 3.

[0057] When the external gizzard conveying mechanism 6 delivers the gizzard 61 to the straightening body 21, the gizzard 61 first enters the straightening groove 23. The straightening body 21 straightens it and works with the gizzard conveying mechanism 6 to press it down and fix it, preventing it from moving around in the straightening groove 23. This ensures that the cuts are neat and uniform during subsequent cutting, and improves the product qualification rate.

[0058] During this process, the elastic drive component 22 is vertically positioned, which can drive the straightening body 21 to move vertically and reset. Specifically, after the gizzard 61 is conveyed and moved into the straightening groove 23, the straightening body 21 will first straighten the gizzard 61. If it continues to move, it will push against the straightening body 21 and apply pressure to the elastic drive component 22. The reaction force generated by the component is applied to the gizzard 61 through the straightening body 21 to fix the gizzard 61. When the gizzard 61 leaves the straightening groove 23, the straightening body 21 resets.

[0059] When the gizzard conveying mechanism 6 drives the gizzard 61 to continue to move backward, the guide needle 41 will first extend into the inner cavity of the gizzard 61, and support the inner cavity through the continued movement of the gizzard 61. The guide needle 41 cooperates with the outer support body 21 to first support and fix the gizzard 61 internally to prevent it from moving around before cutting; secondly, it can expand the inner cavity of the gizzard 61, making it easier to rotate the cutting blade 42 to cut and achieve a neat and uniform cut.

[0060] The automatic cutting mechanism 4 includes a vertically arranged rotary cutting blade 42, which is driven to rotate by a cutting power device. The blade of the rotary cutting blade 42 extends vertically into the straightening groove 23 through the blade receiving gap 24. The rotary cutting blade 42 is located above the front end of the guide needle 41.

[0061] As the gizzard 61 continues to move backward, the rotating cutting blade 42 cuts the upper part of the gizzard 61, while the lower part of the gizzard 61 remains connected. This achieves the action of opening the gizzard 61, replacing the traditional method of manually cutting each gizzard one by one when using a semi-automatic gizzard opening machine. This reduces labor and production costs, improves production efficiency, and eliminates the risk of injury due to improper operation.

[0062] like Figure 5 , Figure 7 As shown in the figure, in order to straighten and fix the gizzard 61 by means of the straightening groove 23, the straightening groove 23 includes a guide section 231 and a straightening and fixing section 232 arranged in sequence along the longitudinal direction. The guide section 231 is a funnel shape with an outward opening. The guide section 231 gradually narrows from front to back and from top to bottom and is connected to the straightening and fixing section 232.

[0063] When the gizzard 61 passes through the straightening groove 23, it is first guided and straightened by the guide section 231. Then, under the action of the elastic drive component 22, the gizzard 61 is fixed by the straightening fixing section 232. During the movement of the gizzard 61, because the guide section 231 is set to gradually narrow from front to back and from top to bottom, the gizzard 61 will be subjected to the downward pressure gradually generated by the guide section 231, which will cause it to enter the straightening fixing section 232 and be fixed.

[0064] like Figures 1 to 3 , Figures 6 to 7 As shown, the elastic drive assembly 22 includes a guide rod 221, a top spring 223, and a compression spring 224. The bottom end of the guide rod 221 passes through the straightener 21 and connects to the frame 1. A nut 222 is threaded onto the guide rod 221, and the nut 222 is located above the straightener 21. The top spring 223 is sleeved on the guide rod 221 and abuts against the frame 1 and the straightener 21. The compression spring 224 is sleeved on the guide rod 221 and abuts against the straightener 21 and the nut 222.

[0065] The top spring 223 and the compression spring 224 interact, simultaneously applying downward elastic pressure and upward elastic force to the straightening body 21, thereby achieving elastic floating and resetting of the straightening body 21. In this structure, the floating strength of the straightening body 21 is affected by the position of the nut 222. When the nut 222 moves downward, the elastic pressure and elastic force on the straightening body 21 increase; conversely, when the nut 222 moves upward, the elastic pressure and elastic force on the straightening body 21 decrease. This allows for individual adjustments to gizzards 61 of different sizes. However, this adjustment is not performed individually for each gizzard 61, because gizzards 61 in the same batch are pre-sorted during gizzard opening, and their sizes are similar. Therefore, before processing, only one adjustment is needed based on the size of the gizzards 61 to be processed.

[0066] Preferably, the straightening body 21 is provided with two or four elastic drive components 22, which can ensure that the straightening body 21 will not sway left or right or back and forth during the up and down floating process, thereby improving the straightening and fixing effect on the gizzard 61.

[0067] like Figures 3 to 9 , Figure 11 As shown, the front end of the needle 41 is provided with a rearward extending and upward inclined guide slope 411, which extends from front to back and is close to the blade of the rotating cutting blade 42. The horizontal length of the guide slope 411 is greater than the length of the gizzard 61. As the gizzard 61 passes through the straightening groove 23, the front end of the guide needle 41 will first extend into the gizzard 61 to support it internally. In order to prevent the guide needle 41 from damaging the integrity of the gizzard 61 during its insertion and to ensure that the cut of the rotary cutter 42 is neat, a guide slope 411 is provided on the guide needle 41. Thus, the gizzard 61 can be gradually supported internally through the guide slope 411. Because the guide slope 411 is an inclined plane, the gizzard 61 will not be cut or torn during the internal support process. Therefore, there will only be one cut on the gizzard 61 produced by the rotary cutter 42, and the cut will be neat; it will also not affect the cutting angle of the rotary cutter 42, and the cut will be uniform.

[0068] The needle 41 is provided with an arc-shaped avoidance part to avoid the rotating cutting blade 42, which allows the rotating cutting blade 42 to extend lower into the straightening groove 23 and approach the needle 41, so as to achieve a complete cutting opening for the gizzard 61.

[0069] The cutting power unit includes a cutting motor 43, which is mounted on the mounting platform 3. A power transmission mechanism 5 is provided between the cutting motor 43 and the rotary cutting blade 42 to transmit power.

[0070] The power transmission mechanism 5 includes a drive sprocket 52 and a driven sprocket 53 connected by a chain 51. The drive sprocket 52 is mounted on the power output shaft of the cutting motor 43, and the driven sprocket 53 is mounted on the cutter shaft 54. The cutter shaft 54 ​​is rotatably mounted below the mounting platform 3 via a bearing seat 55. The rotating cutting blade 42 is mounted on the cutter shaft 54.

[0071] Driven by the cutting motor 43, its power is transmitted to the cutter shaft 54 ​​through the chain 51, causing the cutter shaft 54 ​​to rotate simultaneously. The rotation of the cutter shaft 54 ​​drives the rotating cutting blade 42 to rotate, thereby achieving the rotational cutting of the gizzard 61.

[0072] In this embodiment, rotary cutting blades 42 are respectively installed at both ends of the cutter shaft 54; automatic straightening and positioning mechanisms 2 are respectively provided on the left and right sides of the mounting platform 3. The positions and numbers of the rotary cutting blades 42 and the automatic straightening and positioning mechanisms 2 correspond one-to-one, thereby enabling simultaneous opening operations on both sides of the frame 1, thus forming two processing production lines and improving processing efficiency.

[0073] The mounting platform 3 is mounted on the frame 1 with adjustable height via a screw (obscured in the figure); a number of vertically arranged guide components 31 are installed between the mounting platform 3 and the frame 1. The guide components 31 include guide columns 311 mounted on the frame 1, and guide sleeves 312 are sleeved on the outer side of the guide columns 311. The top of the guide sleeves 312 is fixedly connected to the mounting platform 3.

[0074] The height of the mounting platform 3 is adjustable, which can drive the adjustment of the height of the automatic cutting mechanism 4, that is, adjust the height of the guide pin 41 and the rotating cutting blade 42, so that poultry gizzards 61 of different sizes and types (such as chicken gizzards, duck gizzards or goose gizzards) can be cut, thus expanding the scope of application.

[0075] Example 2

[0076] like Figures 1 to 3 , Figures 10 to 11 As shown in the figure, this embodiment discloses an automatic gizzard opening machine, which includes the poultry automatic uprighting and gizzard opening device in the above embodiment.

[0077] A horizontally arranged gizzard conveying mechanism 6 is installed on the frame 1. The gizzard conveying mechanism 6 is located below the straightening groove 23 and extends to the rear of the rotary cutter 42. The gizzard conveying mechanism 6 adopts a gizzard conveying chain or a gizzard conveying belt. A gizzard tray (not shown in the figure) is provided on the gizzard conveying chain or the gizzard conveying belt. The gizzard tray is used to hold the gizzards 61.

[0078] The gizzard conveying mechanism 6 is used to convey gizzards 61. The gizzard conveying mechanism 6 works in conjunction with the automatic uprighting and positioning mechanism 2 and the automatic cutting mechanism 4 to automatically convey, upright, fix, internally support and cut the gizzards 61, achieving neat and uniform cuts, improving the product qualification rate. At the same time, it can replace the traditional manual hand-cutting method, reducing production costs, improving production efficiency and operational safety.

[0079] Preferably, the position and number of the gizzard conveying mechanism 6 correspond one-to-one with the position and number of the uprighting body 21, the guide needle 41, and the rotary cutting blade 42. In this embodiment, it is preferable that there are two gizzard conveying mechanisms 6, respectively arranged on both sides of the frame 1, which facilitates multiple operators sitting on both sides of the frame 1 to perform gizzard opening work, thereby improving work efficiency. The rotary cutting blade 42 is installed at both ends of the blade shaft 54, which facilitates the simultaneous rotation of two rotary cutting blades 42 by a cutting motor 43, thereby reducing production costs.

[0080] In this embodiment, the automatic gizzard-opening machine first places the gizzards 61 on the gizzard conveying mechanism 6 by the operator. The gizzard conveying mechanism 6 is equipped with several gizzard trays, each containing one gizzard 61. The gizzard conveying mechanism 6 moves the gizzards 61 toward the straightening body 21. After entering the straightening groove 23, the gizzards 61 are straightened, and the straightening body 21 and the gizzard conveying mechanism 6 cooperate to fix the gizzards 61. After fixing, the downstream guide needle 41 provides internal support for the gizzards 61. Then, the rotating cutting blade 42 opens the gizzards. After opening, the gizzards 61 continue to move downward by the gizzard conveying mechanism 6 and are transferred to the holding device for temporary storage.

[0081] During this process, the automatic gizzard opening machine can automatically convey, straighten, fix, internally support and cut the poultry gizzards 61, achieving neat and uniform cuts, improving the product qualification rate. At the same time, it can replace the traditional manual hand-cutting method, reducing production costs, improving production efficiency and enhancing operational safety.

[0082] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
