Description

Technical Field

[0001] The invention relates to a device for peeling poultry gizzards such as chicken gizzards and duck gizzards, and more particularly to a device for separating the outer skin of poultry gizzards. Background Art

[0002] In the batch processing of poultry gizzards, especially chicken gizzards, the first step is to remove the yellow gizzard skin on the surface of the gizzards. The peeling equipment in the existing technology has a low degree of automation and low production efficiency. Summary of the Invention

[0003] To address the above issues, the present invention aims to provide a highly efficient poultry gizzard peeling device. This device utilizes a unique feeding mechanism and multiple sets of peeling components operating simultaneously to achieve efficient production. Furthermore, the present invention provides a poultry gizzard peeling device with a compact structure and high transmission efficiency.

[0004] To achieve the above-mentioned object, the present invention provides a poultry gizzard peeling machine, comprising an inner cylinder having a feed port for feeding from the inside out at the rear; one or multiple circular rings or arc-shaped plates arranged axially in the front of the inner cylinder; a plurality of parallel and axially staggered feed rods arranged outside the front of the inner cylinder; an outer cylinder that rotates relative to the inner cylinder; a plurality of peeling thread groups fixedly arranged in the circumferential direction of the inner wall of the outer cylinder; each thread group includes two mutually meshing externally threaded rods arranged parallel to the axial direction of the outer cylinder; one of the two externally threaded rods is a driving rotating screw and the other is a driven rotating screw. The axial direction of the inner cylinder is arranged horizontally.

[0005] In the optimal mode, the cylinder with the feed port at the rear is a conical cylinder (the feeding efficiency of the cylindrical form is low); a plurality of the feed ports are arranged at intervals along the circumference of the conical cylinder, thereby improving the feeding efficiency and achieving the desired function.

[0006] The inner cylinder of the present invention can be fixed or rotated, and the outer cylinder drives the thread group to rotate relative to the inner cylinder. In addition, the two external threaded rods of each thread group can realize rotation. The above-mentioned rotation actions can be realized by setting motor drives separately, as long as the setting of the drive motor does not interfere and the operation is guaranteed.

[0007] In order to achieve the goals of compact structure, reasonable drive and efficient operation, the present invention provides an optimal driving scheme as follows: the inner cylinder is connected to a driving motor for driving rotation, and a driving sprocket or driving pulley is provided on the output shaft of the driving motor. The driving sprocket or driving pulley drives a driving gear to rotate through a driven sprocket or pulley, and the driving gear drives the driven gear fixed to one end of the outer cylinder to rotate, thereby driving the outer cylinder to rotate; a toothed disc is provided on one side of the inner end of the inner cylinder and is driven to rotate by the driving motor of the inner cylinder; the outer teeth of the toothed disc realize the opposite rotation of the two externally threaded rods in each of the threaded groups by respectively engaging with the driving gears on the end sides of the actively rotating screw.

[0008] In addition, during operation, the thread rotation direction of the two screws should ensure that the gizzards are pushed toward the front end of the cylinder during rotation. The gap in the ring serves as a channel for feeding the gizzards. The end face of the inner cylinder is flush with the end face of the outermost ring.

[0009] Preferably, each of the circular rings has one or more notches. These notches allow the gizzards to be fed in the discharge direction, and the processed gizzards can be discharged through the notches. Alternatively, no notches are provided, and the gizzards are fed in the discharge direction through the radial gap between the inner cylindrical ring and the threaded assembly, and the processed gizzards can be discharged through the radial gap between the ring and the threaded assembly.

[0010] The circular ring can be replaced by an arc-shaped plate; a plurality of the arc-shaped plates are staggered in the axial direction of the cylinder, and the axial projection of the plurality of the arc-shaped plates forms a ring.

[0011] In a preferred embodiment, annular brackets are provided at the front and rear ends of the outer cylinder, and the annular brackets are fixed with bolts through threaded holes to the end bearing frames for supporting the two externally threaded rods of each threaded group; and bearings are provided to connect the smooth rod parts at the ends of the two externally threaded rods to ensure the rotation of the two externally threaded rods.

[0012] In addition, the material-moving rod can be a protrusion provided on the outer wall of the inner cylinder. In a preferred embodiment, the material-moving rod of the present invention is fixed at intervals on the annular end surface of one side of the circular ring.

[0013] To improve efficiency, the thread assembly should cover the entire inner wall of the outer cylinder as closely as possible. When processing gizzards, the clearance between the feed rod, inner cylinder, and outer cylinder, as well as the placement of the rings and the dimensions of the thread assembly threads, should meet gizzard processing requirements, ensuring that the gizzards can be fed from the feed end to the discharge end while the thread assembly can separate the gizzard skin. The specific dimensions will be determined based on the size of the gizzard and through limited testing.

[0014] In a preferred embodiment, the inner cylinder and the outer cylinder are arranged on the frame in a horizontal axial manner, and are equipped with a suspended feeding trough, the front end of which penetrates into the inner cylinder to the feeding port.

[0015] The poultry gizzard peeling device is particularly suitable for the operation of separating the film on the surface of the chicken gizzard, has the characteristics of compact structure and efficient transmission, and achieves the purpose of efficient production by operating multiple groups of peeling components simultaneously.

[0023] like Figures 1 to 4 The poultry gizzard peeling machine of the present invention comprises an inner cylinder with a cylindrical front portion and a conical rear portion, which rotates integrally. Figure 2 As shown, the conical surface of the conical cylinder 10 is provided with feed ports 11 spaced apart for feeding from the inside out. One or more rings 12 (three shown, depending on specific processing requirements) with notches 13 are arranged axially on the cylinder's exterior. Several axially extending material removal rods 14 are also provided on the cylinder's exterior. The conical cylinder 10 is the optimal configuration; equivalent alternatives may be used, as long as it serves the feeding function.

[0024] A counter-rotating outer cylinder (not shown in the figure) is also provided outside the inner cylinder; a plurality of peeling thread groups 8 are fixedly arranged in the circumferential direction of the inner wall of the outer cylinder; each thread group 8 includes two external thread rods arranged parallel to the axial direction of the outer cylinder and meshing with each other; one of the two external thread rods is an active rotating screw 16, and the other is a driven rotating screw 17.

[0025] like Figure 1As shown, the output shaft of the inner cylinder's drive motor 1 is provided with a driving sprocket or pulley 4. The driving sprocket or pulley 4 drives a driving gear 5 via a driven sprocket or pulley 2. The driving gear 5 then drives a driven gear 19 fixed to one end of the outer cylinder, thereby driving the outer cylinder to rotate. Reference numeral 3 in the figure represents a transmission belt.

[0026] like Figure 4 As shown, a geared disc 20 is located inside the conical cylinder and is driven by the inner cylinder's drive motor. The external teeth of the geared disc 20 engage the drive gears 15 on the ends of the active rotating screws 16, respectively, to achieve the opposite rotation of the two externally threaded rods in each threaded group 8. During operation, the thread rotation of the two screws is such that the gizzards are propelled toward the front end of the cylinder during rotation.

[0027] like Figure 1 As shown, annular brackets 7 are provided at the front and rear ends of the outer cylinder. Bolts are provided through threaded holes 6 to fix the end bearing brackets 18 used to support the two externally threaded rods of each threaded group 8. In addition, the end surface of the inner cylinder is flush with the end surface of the outermost ring 12.

[0028] like Figure 3 As shown, the material moving rods 14 are fixed at intervals on the inner annular end surface of the ring 12 .

[0029] Preferably, the thread group 8 completely covers the inner wall of the outer cylinder. The inner and outer cylinders are mounted on a frame 9 in a horizontal (or nearly horizontal) axial orientation. Furthermore, a suspended feed chute (not shown) is provided, the front end of which extends deep into the inner cylinder to the feed port 11 for feeding gizzards.

[0030] like Figure 5 As shown, the present invention provides an arrangement of the inner cylinder, the curved plates, and the material-moving rod, wherein the plurality of curved plates are staggered in the axial direction of the cylinder, and the plurality of groups of curved plates at different axial positions are axially projected into a ring. The material-moving rod is arranged between the curved plates.

[0031] Figure 6 In the embodiment shown, the material-moving rods are distributed throughout the outer wall area of ​​the inner cylinder outside the arc-shaped plate. The material-moving rods can be fixed on both sides of the arc-shaped plate or on the outer wall of the inner cylinder.

[0032] Figure 7 In the embodiment, the ring is not provided with a notch, and the chicken gizzards or poultry gizzards are fed in the discharge direction through the radial gap between the inner cylinder ring and the thread group, and the processed poultry gizzards can be discharged through the radial gap between the ring and the thread group.

[0033] During operation, the feed chute feeds gizzards through the feed port 11. The gizzards are gradually fed toward the front end through the notch in the outer ring 12 of the inner cylinder. The rotational direction of the two externally threaded rods of the thread assembly 8 ensures the gizzards' direction. The gizzards are flipped by the feed lever 14, and the rotating, meshing rods engage the gizzards, freeing the outer membrane. Finally, they are pushed out through the notch in the frontmost ring 12, completing the process.

[0034] The reverse rotation of the inner and outer cylinders and the simultaneous operation of multiple thread groups in the present invention ensure processing efficiency; and the thread group 8 rotates with the outer cylinder, ensuring the effective working state of each thread group.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
