Description

Technical Field

[0001] This utility model relates to the field of poultry processing technology, and in particular to an automatic gizzard positioning 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 the predetermined position during cutting, resulting in a change in the cutting position and thus reducing the product qualification rate. Utility Model Content

[0006] In view of this, the technical problem to be solved by this utility model is to provide a second type of automatic poultry positioning device and automatic gizzard opening machine, which can position and restrain poultry gizzards, making it easier to open them later, improving product qualification rate and reducing production costs.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] An automatic gizzard alignment device is provided, which is installed above the frame of an automatic gizzard opening machine. The automatic gizzard alignment device includes an installation platform, which is located above the frame. A top pressing mechanism and a side clamping mechanism are installed on the installation platform.

[0009] The top pressing mechanism includes a pressure rod arranged longitudinally, the pressure rod being located below the mounting platform, and the pressure rod being installed below the mounting platform by means of a vertical reset assembly that can float up and down;

[0010] The side clamping mechanism includes two symmetrically arranged clamping components. Each clamping component includes a toothed plate and a clamping rod fixed below the toothed plate. The toothed plate is rotatably mounted on the mounting platform, and the two toothed plates mesh with each other. A lateral reset component is provided between one of the toothed plates and the mounting platform. The clamping rod is arranged longitudinally and located on both sides below the pressure rod. An alignment channel for aligning the gizzard is formed between the clamping rods and the pressure rod on both sides.

[0011] Preferably, the pressure rod and the clamping rod have the same structure, both including a rod body arranged longitudinally, and the front end of the rod body is provided with an arc-shaped guide portion.

[0012] Preferably, the guide portion of the pressure rod is bent vertically upward, and the guide portion of the clamping rod is bent laterally outward;

[0013] The guide portion of the pressure rod and the guide portion of the clamping rod cooperate to form a flared, outward-facing trumpet shape.

[0014] Preferably, the guide portion of the clamping rod is located longitudinally behind the guide portion of the pressure rod;

[0015] The number of clamps is two, and the two clamps are arranged vertically parallel to each other.

[0016] Preferably, the number of vertical reset components is two, and the vertical reset component includes:

[0017] A vertical guide rod, the top end of which penetrates the mounting platform;

[0018] An upper limit nut is threadedly connected to the vertical guide rod and is located above the mounting platform.

[0019] A lower limit nut, which is threadedly connected to the vertical guide rod, is located below the mounting platform;

[0020] A vertical compression spring is sleeved on the vertical guide rod and abuts against the lower limit nut and the mounting platform.

[0021] Preferably, the toothed plate includes a vertically arranged plate body, and the inner side of the plate body is provided with teeth;

[0022] The bottom of the plate is fixed with an inclined support arm. The bottom end of the support arm is inclined inward along the lateral direction. The support arms on the two toothed plates intersect to form an X-shaped structure. The clamping rod is fixed on the support arm and is located below the intersection of the two support arms.

[0023] Preferably, the mounting platform is equipped with a longitudinally arranged mounting shaft, and the plate is rotatably mounted on the mounting shaft.

[0024] Preferably, a vertical plate is fixed on the mounting platform, and the lateral reset assembly is installed between the vertical plate and one of the toothed plates; the lateral reset assembly includes:

[0025] A transverse guide rod, the inner end of which is connected to the toothed plate, and a vertically arranged elongated hole is provided on the upright plate, the outer end of which passes through the elongated hole;

[0026] An adjusting nut is threaded onto the transverse guide rod and is located on the inner side of the vertical plate;

[0027] A transverse compression spring is sleeved on the transverse guide rod and abuts against the adjusting nut and the vertical plate.

[0028] Preferably, the mounting platform is mounted on the frame via four support rods.

[0029] An automatic gizzard opening machine, characterized in that the automatic gizzard opening machine includes the above-mentioned automatic gizzard positioning device;

[0030] The frame is equipped with a rotary cutting blade and a guide pin. The rotary cutting blade is vertically positioned and driven to rotate by a cutting power device. The rotary cutting blade is located longitudinally behind the pressure rod. The front end of the guide pin extends longitudinally into the positioning channel.

[0031] The frame is equipped with a longitudinally arranged gizzard conveying mechanism, which is located below the pressure bar and extends to the rear of the rotary cutter. A gizzard tray is provided on the gizzard conveying mechanism.

[0032] After adopting the above technical solution, the beneficial effects of this utility model are:

[0033] The automatic gizzard positioning device of this application is used to be installed above the frame of an automatic gizzard opening machine. The automatic gizzard positioning device includes an installation platform, which is set above the frame. A top pressing mechanism and a side clamping mechanism are installed on the installation platform. The top pressing mechanism is used to press down and fix the gizzard, and the side clamping mechanism is used to clamp and fix the gizzard from both sides. The two mechanisms cooperate with each other to complete the positioning and fixation of the gizzard, preventing the gizzard from moving when it is opened, which would affect the product qualification rate.

[0034] Specifically, the top pressing mechanism includes a pressure rod located below the mounting platform. The pressure rod is mounted below the mounting platform and can float up and down via a vertical reset assembly. The side clamping mechanism includes two clamping assemblies, each consisting of a toothed plate and clamping rods fixed below the toothed plate. The toothed plate is rotatably mounted on the mounting platform, and the two toothed plates mesh with each other. A transverse reset assembly is provided between one of the toothed plates and the mounting platform. The clamping rods are arranged longitudinally and located on both sides below the pressure rod. The clamping rods and the pressure rod on both sides form an alignment channel for aligning the gizzard.

[0035] When the gizzard moves under the pressure bar, the pressure bar first presses it down to secure it, preventing it from falling off the gizzard tray. After the pressure bar secures it, the gizzard may tilt to one side due to the pressure. As the gizzard continues to move, it is clamped and secured by two clamping rods, returning it to its original position. Thus, the two clamping rods and one pressure bar complete the pressing and clamping of the gizzard, preventing it from swaying within the positioning channel, achieving gizzard correction and restraint. When the downstream rotating cutter makes an incision in the gizzard, it ensures a neat and uniform cut, improving the product qualification rate.

[0036] Meanwhile, the automatic gizzard opening machine of this application includes an automatic gizzard positioning device. A rotary cutting blade and a guide needle are installed on the frame. The rotary cutting blade is vertically positioned behind the pressure rod along the longitudinal direction. The front end of the guide needle extends longitudinally into the positioning channel. When the gizzard continues to move backward, the guide needle first extends into the inner cavity of the gizzard and supports the inner cavity through the continued movement of the gizzard. The guide needle cooperates with the pressure rod on the outside and the clamping rods on both sides to first support and fix the gizzard internally, preventing it from moving randomly before cutting. Secondly, it can expand the inner cavity of the gizzard, making it easier for the rotary cutting blade to cut and achieve a neat and uniform cut.

[0037] The gizzard continues to move backward, and the rotating cutting blade cuts the upper part of the gizzard while the lower part remains connected. This action opens the gizzard, replacing the traditional semi-automatic gizzard-opening machine that required manual cutting one by one. This reduces labor and production costs, improves production efficiency, and eliminates the risk of injury from improper operation.

[0038] A gizzard conveying mechanism is mounted on the frame, located below the pressure bar and extending behind the rotary cutter. A gizzard tray is mounted on the conveying mechanism. This mechanism, in conjunction with the top pressing mechanism and the side clamping mechanism, conveys and positions the gizzards. Simultaneously, it works with the rotary cutter and guide needle to automatically convey, position, fix, internally support, and cut the gizzards, resulting in neat and uniform cuts, improving product qualification rates. Furthermore, it replaces the traditional manual cutting method, reducing production costs, increasing production efficiency, and enhancing operational safety. Attached Figure Description

[0055] 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.

[0056] Example 1

[0057] like Figures 1 to 4 As shown in the diagram, this utility model discloses an automatic orthogonal device for opening the gizzard 72. The gizzard 72 mainly refers to chicken gizzards, duck gizzards, and goose gizzards; this embodiment uses a chicken gizzard as an example.

[0058] An automatic gizzard positioning device is installed above the frame 1 of an automatic gizzard opening machine. The device includes a mounting platform 2, which is positioned above the frame 1. A top pressing mechanism 3 and a side clamping mechanism 4 are mounted on the mounting platform 2. The mounting platform 2 is mounted to the frame 1 via four support rods located outside the top pressing mechanism 3 and the side clamping mechanism 4; alternatively, the mounting platform 2 is mounted to the frame 1 via two support plates. The top pressing mechanism 3 presses down to fix the gizzard 72 in position, while the side clamping mechanism 4 clamps the gizzard 72 from both sides to fix its posture. The two mechanisms work together to position and fix the gizzard, preventing movement during opening and ensuring product quality.

[0059] In this application, the top pressing mechanism 3 includes a pressure rod 31 arranged longitudinally, which is located below the mounting platform 2. Specifically, the pressure rod 31 is installed below the mounting platform 2 by means of a vertical reset assembly 32. The side clamping mechanism 4 includes two symmetrically arranged clamping assemblies 41. Each clamping assembly 41 includes a toothed plate 411 and a clamping rod 412 fixed below the toothed plate 411. The toothed plate 411 is rotatably mounted on the mounting platform 2, and the two toothed plates 411 mesh with each other. A transverse reset assembly 42 is provided between one of the toothed plates 411 and the mounting platform 2. The clamping rod 412 is arranged longitudinally and located on both sides below the pressure rod 31. The clamping rods 412 and the pressure rod 31 on both sides form an alignment channel for aligning the gizzard 72.

[0060] When the gizzard 72 is conveyed by the gizzard conveying mechanism 7 and moved below the pressure bar 31, the pressure bar 31 first presses it down to fix its position, preventing it from falling off the gizzard tray 71. After the pressure bar 31 fixes it, the gizzard 72 may be tilted to one side due to the pressure, i.e., its posture is incorrect. As the gizzard 72 continues to move, it will be clamped and fixed in posture by the two clamping rods 412, returning it to its correct position. Thus, the two clamping rods 412 and one pressure bar 31 complete the pressing and fixing of the gizzard 72 and the clamping and fixing of its posture, preventing it from swinging around in the correct position channel, thereby correcting and restraining the gizzard 72. When the downstream rotary cutting blade 5 makes an opening in the gizzard 72, it can ensure that the cut is neat and uniform, improving the product qualification rate.

[0061] Preferably, the pressure rod 31 and the clamping rod 412 have the same structure, both including a rod body 311 arranged longitudinally, with an arc-shaped guide portion 312 at the front end of the rod body 311. The guide portion 312 of the pressure rod 31 bends vertically upwards, while the guide portion 312 of the clamping rod 412 bends horizontally outwards. The guide portions 312 of the pressure rod 31 and the guide portions 312 of the clamping rod 412 cooperate to form a flared, outward-facing trumpet shape. When the gizzard 72 is moved into the positioning channel, the trumpet shape formed by the guide portion 312 can guide and straighten the gizzard 72, ensuring its accurate entry into the positioning channel.

[0062] The guide portion 312 of the clamping rod 412 is located longitudinally behind the guide portion 312 of the pressure rod 31, thereby enabling the gizzard 72 to be first pressed down to fix its position and then clamped to fix its posture, thus improving the accuracy of fixing the gizzard 72.

[0063] There are two clamping rods 412, which are arranged vertically in parallel to each other, so that the position and posture of gizzards 72 of different sizes can be fixed, and the applicability is wide.

[0064] In this application, there are two vertical reset components 32, which can apply pressure to all gizzards 72 below the pressure bar 31 and fix the position of all gizzards 72 below the pressure bar 31.

[0065] The vertical reset assembly 32 includes a vertical guide rod 321, an upper limit nut 322, a lower limit nut 323, and a vertical compression spring 324. The top end of the vertical guide rod 321 passes through the mounting platform 2. The upper limit nut 322 is threaded to the vertical guide rod 321 and is located above the mounting platform 2. The lower limit nut 323 is threaded to the vertical guide rod 321 and is located below the mounting platform 2. The vertical compression spring 324 is sleeved on the vertical guide rod 321 and abuts against the lower limit nut 323 and the mounting platform 2.

[0066] The vertical compression spring 324 applies pressure to the pressure rod 31. When the gizzard 72 enters below the pressure rod 31, it can lift the pressure rod 31. Using the pressure applied by the vertical compression spring 324, the pressure rod 31 presses down and fixes the gizzard 72.

[0067] In this application, the toothed plate 411 includes a vertically arranged plate body with teeth on the inner side of the plate body. The teeth on the two toothed plates 411 mesh with each other, and when one toothed plate 411 rotates, it can drive the other toothed plate 411 to rotate together through the teeth.

[0068] An inclined support arm 43 is fixed at the bottom of the plate. The bottom end of the support arm 43 is inclined inward along the horizontal direction. The support arms 43 on the two toothed plates 411 intersect to form an X-shaped structure. A clamping rod 412 is fixed on the support arm 43. The clamping rod 412 is located below the intersection of the two support arms 43.

[0069] The mounting platform 2 is equipped with a longitudinally arranged mounting shaft 44, and the plate is rotatably mounted on the mounting shaft 44. When the gizzard 72 enters the positioning channel and abuts against one of the clamping rods 412, it can push the clamping rod 412 to move outward. At this time, the clamping rod 412 drives the toothed plate 411 to rotate around the axis of the mounting shaft 44 through the support arm 43. Specifically, it also drives the top of the toothed plate 411 to rotate outward; at the same time, through the meshing teeth, it drives the other toothed plate 411 to rotate outward as well.

[0070] A vertical plate 45 is fixed on the mounting platform 2, and a transverse reset assembly 42 is installed between the vertical plate 45 and one of the toothed plates 411. The transverse reset assembly 42 includes a transverse guide rod 421, an adjusting nut 422, and a transverse compression spring 423. The inner end of the transverse guide rod 421 is connected to the toothed plate 411, and a vertically arranged elongated hole is opened on the vertical plate 45. The outer end of the transverse guide rod 421 passes through the elongated hole. The adjusting nut 422 is threaded to the transverse guide rod 421 and is located on the inner side of the vertical plate 45. The transverse compression spring 423 is sleeved on the transverse guide rod 421 and abuts against the adjusting nut 422 and the vertical plate 45.

[0071] When the toothed plate 411 rotates outward, it compresses the transverse compression spring 423 via the adjusting nut 422. Simultaneously, it drives the transverse guide rod 421 to rotate around the axis of the mounting shaft 44. To avoid interfering with the movement of the transverse guide rod 421, an elongated hole is provided on the upright plate 45 to accommodate the rotation of the toothed plate 411 and the compression of the transverse compression spring 423. After the gizzard 72 finishes opening, no more gizzards 72 pass through the positioning channel. At this point, the elasticity of the transverse compression spring 423 is released, and the adjusting nut 422 drives the toothed plate 411 to rotate in the opposite direction, achieving a reset. The adjusting nut 422 here is used to adjust the pressure of the transverse compression spring 423, ensuring that gizzards 72 of different sizes can be clamped and fixed in a fixed position.

[0072] Example 2

[0073] like Figure 1 , Figures 4 to 7 As shown in the figure, this embodiment discloses an automatic gizzard opening machine for conveying poultry gizzards 72 and cooperating with the automatic gizzard positioning device in the above embodiment to perform the opening action.

[0074] The frame 1 is equipped with a rotary cutting blade 5 and a guide needle 6. The rotary cutting blade 5 is vertically positioned and driven to rotate by a cutting power device (not shown in the figure). The rotary cutting blade 5 is located behind the pressure rod 31 along the longitudinal direction. The front end of the guide needle 6 extends into the positioning channel along the longitudinal direction.

[0075] As the gizzard 72 continues to move backward, the guide needle 6 first inserts into the inner cavity of the gizzard 72 and supports its inner cavity as the gizzard 72 continues to move. The guide needle 6 cooperates with the outer pressure rod 31 and the clamping rods 412 on both sides to first support and fix the gizzard 72 internally, preventing it from moving around before cutting; secondly, it can expand the inner cavity of the gizzard 72, making it easier to rotate the cutting blade 5 to cut and achieve a neat and uniform cut.

[0076] The gizzard 72 continues to move backward, and the rotating cutting blade 5 cuts the upper part of the gizzard 72, but the lower part of the gizzard 72 remains connected. This achieves the action of opening the gizzard 72, replacing the traditional method of manually cutting each gizzard one by one when using a semi-automatic gizzard opening machine. This reduces labor costs and production costs, improves production efficiency, and eliminates the risk of injury due to improper operation.

[0077] A gizzard conveying mechanism 7 is installed on the frame 1 along the longitudinal direction. The gizzard conveying mechanism 7 is located below the pressure bar 31 and extends to the rear of the rotary cutter 5. A gizzard tray 71 is provided on the gizzard conveying mechanism 7.

[0078] The gizzard conveying mechanism 7 is used to convey gizzards 72, which are placed in a gizzard tray 71. The gizzard conveying mechanism 7 works in conjunction with the top pressing mechanism 3 and the side clamping mechanism 4 to convey and position the gizzards 72. At the same time, it works in conjunction with the rotating cutting blade 5 and the guide needle 6 to automatically convey, position, fix, internally support, and cut the gizzards 72, resulting in neat and uniform cuts and improving the product qualification rate. It can also replace the traditional manual hand-held cutting method, reducing production costs, improving production efficiency, and enhancing operational safety.

[0079] 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.
