Description

Technical Field

[0001] This utility model relates to the field of poultry slaughtering and processing equipment, and in particular to the auxiliary mechanism of a poultry leg deboning machine. Background Technology

[0002] With rising living standards and a faster pace of life, the demand for convenient and quick food has increased significantly. Chicken, a common type of white meat, is widely popular due to its rich nutrition, low fat content, and ease of cooking. Deboning is a crucial step in chicken processing. Traditional manual deboning is inefficient, costly, labor-intensive, and yields inconsistent quality. Therefore, the research and application of automated deboning equipment has become an inevitable trend in the industry.

[0003] Currently, existing chicken leg deboning machines include mechanical extrusion separation, positioning cutting separation, and pull-down separation. For example, patent CN211268392U discloses a mechanical elastic extrusion chicken leg deboning machine, including a frame, a column fixed to the upper side wall of the frame, a deboning tube fixed to the upper end of the column, a feed inlet on the upper side wall of the deboning tube, a discharge outlet on the lower side wall of the deboning tube, a sliding opening at the end of the deboning tube, a push rod sliding within the sliding opening, the outer diameter of the push rod matching the inner diameter of the sliding opening, the push rod being parallel to the upper surface of the frame, and one end of the push rod outside the deboning tube being fixed to an arc-shaped plate, the arc-shaped plate being positioned between the arc-shaped plate and the outer wall of the deboning tube. A telescopic spring is fixed, and a motor is fixed on the frame. The drive end of the motor is fixed with a cam located on one side of the arc plate. Two support columns are fixed on the upper side wall of the frame. Collection box one and collection box two are respectively placed on the two support columns, located below the discharge port and below the end of the deboning tube. In use, after the chicken leg is put into the deboning tube, the motor drives the cam to rotate. When the longer end of the cam rotates to contact the arc plate, it pushes the arc plate and the push rod to move towards the chicken leg. The push rod contacts the leg bone in the middle of the chicken leg and pushes the chicken leg forward. When the chicken leg contacts the conical frame, the leg bone is inserted into the opening and pushed out. Patent CN211268392U discloses a chicken leg deboning machine, including a worktable. Multiple support columns are fixedly mounted on the top of the worktable, with the tops of each support column fixedly connected to the bottom of a top plate. A drive motor is fixedly mounted in the middle of the top of the top plate, and the output shaft of the drive motor is fixedly connected to the middle of the top of a turntable. Multiple rotating rods are fixedly mounted on the bottom of the turntable, and a support platform is fixedly mounted on the bottom of each rotating rod. A deboning plate is fixedly mounted on one side of the top of each support platform, and a deboning groove is formed in the middle of one side of each deboning plate. A deboning hole is formed in the middle of the bottom of the inner wall of each deboning groove. A sleeve is slidably connected to the middle of the outer wall of each rotating rod, and a deboning rod is fixedly mounted on one side of each sleeve. A deboning knife is fixedly mounted on the bottom of one side of one of the support columns. In use, the chicken leg is first placed in the deboning groove. Under the clamping force of the first spring and the second clamping plate, the chicken leg is held in place. Then, the drive motor switch is turned on, causing the turntable to rotate. The turntable rotates the rotating rod, which in turn moves the sleeve, thus causing the first slider to move within the spiral groove. When the first slider reaches the lowest point of the spiral groove, the pressure of the deboning rod squeezes the chicken leg bone downwards, thereby expelling the bone from the deboning hole, completing the deboning of the chicken leg. The two patents mentioned above, because they directly squeeze out the leg bone, result in a significant amount of meat remaining on the bone, leading to chicken waste.The patented chicken leg meat-bone separator, published under CN209202001U, includes a main frame, a chicken leg conveying line, a pre-cut tendon assembly, a positioning assembly, a pre-peeling assembly, a ring-cut tendon assembly, a post-peeling assembly, a roller separation assembly, a leg meat cutting assembly, and a leg bone unloading assembly. The roller separation assembly includes a roller, an upper end plate, a lower end plate, a drive motor, and several sets of robotic arms. The robotic arms and track design pull the chicken meat downwards to separate it from the leg bone, and then the leg meat cutting assembly cuts the chicken meat. This patented technology includes a pre-peeling assembly and a ring-cut tendon assembly, which can reduce the amount of meat remaining on the leg bone. However, because the chicken meat connected to the tendon is prone to breakage during the pulling and separating process, a large amount of chicken meat remains at the connection point between the leg bone and the chicken meat, resulting in a high meat-bone ratio. The leg meat cutting assembly cuts the leg meat separated to the lower end of the leg bone, but due to differences in chicken leg size and clamping positions, bone breakage is easily caused, affecting the quality of the chicken meat.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly. In the embodiments of this utility model, the front end and front side refer to the direction of transportation and the entry end of transportation, while the rear end and rear side refer to the exit end of transportation.

[0042] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figure 1 As shown, the auxiliary mechanism of the poultry leg deboning machine of this utility model is used to cut the tendon part shown in the figure. Since the strength of the tendon is greater than that of the chicken meat, when the chicken meat is peeled downwards, the chicken meat is easily pulled off and remains on the tendon due to the action of the tendon. After the tendon is cut off, the auxiliary mechanism of the poultry leg deboning machine of this utility model will pull off the chicken meat from the broken tendon when the chicken meat continues to be peeled downwards, so that the chicken meat is peeled off and the amount of chicken meat remaining on the leg bone is reduced.

[0044] Example 1

[0045] This embodiment provides an auxiliary mechanism for a poultry leg deboning machine, such as... Figure 3 As shown, it includes a mounting plate 1, a cleaver 2, and a torsion spring 3. The mounting plate 1 is connected to the frame of the deboning device through a first slotted hole 11, and is used to connect the various components; the cleaver 2 is located at the tendon where the chicken meat is pulled apart from the chicken leg bone, and is connected to the mounting plate 1 through the torsion spring 3.

[0046] To facilitate adjustment of the distance between the cleaver 2 and the chicken leg bone, a second groove hole 12 can be provided on the mounting plate 1. A fixing sleeve 13 is slidably connected to the second groove hole 12. The fixing sleeve 13 and the cleaver 2 are connected by a fixing shaft 7. The fixing shaft 7 passes through the center of the torsion spring 3. One end of the torsion spring 3 is connected to the cleaver 2, and the other end is connected to the fixing sleeve 13. The cleaver 2 is rotatably connected to the fixing shaft 7. A nut is provided at the lower end of the fixing shaft 7. By tightening the nut, the fixing sleeve 13 is fixed in the set position of the second groove hole 12.

[0047] In this embodiment, the cleaver 2, in its initial state, is located on the operating line of the chicken leg deboning device. In a pull-down, separating chicken leg deboning machine, one end of the chicken leg bone is clamped and fixed by a clamping structure, while the chicken meat is generally held and pulled downwards by a peeling mechanism. The peeling mechanism is generally a clamping plate located on both sides of the chicken leg bone. The clamping plate clamps the chicken leg bone from the upper end and moves downwards. During the downward peeling process, the clamping plate also moves along the peeling line. Figure 2 As described above, the cleaver 2 of this application deflects under the impact of the clamping plate, and then rebounds under the action of the torsion spring 3 to cut the tendon. Since the clamping plate also moves downwards, after the cleaver 2 cuts the tendon, the clamping plate is located below the cleaver 2, so it will not interfere with the cleaver 2 during its rebound. In this embodiment, the front end of the cleaver 2 is used to cut the tendon. As the chicken leg continues to move along the peeling line, after the tendon is cut, the chicken leg bone pushes the cleaver 2 aside and passes through the front end of the cleaver 2. For the process of peeling the chicken leg, please refer to the content disclosed in the patent with publication number CN209202001U.

[0048] To facilitate adjustment of the position of the cleaver 2, the mounting plate 1 can be connected to the frame of the deboning device by bolts through the first slotted hole 11 and the second slotted hole 12, thereby adjusting the height and length of the cleaver 2 and the distance between the cleaver and the chicken leg.

[0049] The advantage of this embodiment is that it relies on the rebound force after the impact of the clamping plate to cut the tendon, which is simple in structure and low in cost.

[0050] Example 2

[0051] While Embodiment 1 possesses the advantages described above, it also has certain drawbacks. For instance, the impact of the clamping plate can cause some wear on the cleaver, and debris may be generated during the impact process, contaminating the chicken meat. Therefore, this embodiment provides an auxiliary mechanism for the poultry leg deboning machine.

[0052] like Figure 4-5 The auxiliary mechanism for the poultry leg deboning machine provided in this embodiment includes, in addition to the mounting plate 1, the chopping blade 2, and the torsion spring 3, an adjusting plate 5. The adjusting plate 5 is located between the torsion spring 3 and the mounting plate 1. One end of the torsion spring 3 is connected to the adjusting plate 5, and the other end is connected to the chopping blade 2. The adjusting plate 5 and the chopping blade 2 are connected via a rotating shaft 6, which passes through the center of the torsion spring 3 and is rotatably connected to the adjusting plate 5. When the chopping blade 2 cuts the tendons, it is impacted by the chicken leg bone, causing the chopping blade 2 to rotate within a certain range due to the restriction of the torsion spring 3. This prevents the chopping blade 2 from excessively cutting the chicken leg bone, ensuring that only the tendons are cut. To facilitate adjustment of the height and angle of the chopping blade 2, an arc-shaped hole 51 is provided on the adjusting plate 5. The adjusting plate 5 and the mounting plate 1 are connected via a telescopic mechanism 4.

[0053] Specifically, the telescopic mechanism 4 includes: a connecting plate 41, a guide rod 42, and a driving device 43.

[0054] The connecting plate 41 is connected to the adjusting plate 5, and the connecting plate 41 is provided with an adjusting hole 411 for adjusting the distance between the cleaver 2 and the chicken leg; one end of the guide rod 42 is connected to the connecting plate 41; the driving device 43 is connected to the other end of the guide rod 42 and is used to drive the guide rod 42 to perform linear movement. The driving device 43 is signal-connected to a proximity switch 45.

[0055] To facilitate adjustment of the length and height of the cleaver, the mounting plate 1 has a first slotted hole 11, which is connected to the frame of the bone-scraping device by bolts.

[0056] In this embodiment, the drive device 43 can be a cylinder, an electromagnetic push rod, or a motor-connecting rod assembly. When the drive device 43 is a motor-connecting rod assembly, it specifically includes a motor 431, a rocker arm 432, and a connecting rod 433. The motor 431 is connected to the mounting plate 1 or the frame of the bone-removing device; one end of the rocker arm 432 is connected to the drive end of the motor 431, and the other end is connected to one end of the connecting rod 433, with the other end of the connecting rod 433 connected to the guide rod. During the rotation of the motor 431, the guide rod 42 undergoes linear motion via the rocker arm 432 and the connecting rod 433. To ensure the stability of the linear motion of the guide rod, a linear bearing 44 is provided on the mounting plate 1, and the guide rod 42 is slidably connected to the linear bearing 44.

[0057] In the initial state, the chopper 2 of the auxiliary mechanism for the poultry leg deboning machine in this embodiment is in a retracted state. When the proximity switch 45 detects that the chicken meat is nearing the breaking limit of the chicken leg bone, the control system activates the drive device 4 to extend the chopper 2 to the tendon position, causing the chopper 2 to cut the tendon. After the control system checks that the proximity switch 45 has detected that the chopper 2 has cut the tendon, it immediately returns the chopper 2 to the retracted position, waiting for the next extension command. The torsion spring 3 is used to prevent the chopper 2 from being overloaded. Due to the design of the auxiliary mechanism for the poultry leg deboning machine of this utility model, the chicken meat is easier to separate from the chicken leg bone. After the chopper cuts the tendon, the chicken meat is easier to separate from the chicken leg bone. Often, it is not necessary to use the leg meat cutting component disclosed in the patent with publication number CN209202001U to completely separate the chicken meat. Alternatively, the leg meat cutting component can be set slightly away from the lower end of the chicken leg bone to cut the last connected chicken meat when the chicken meat and chicken leg bone are not completely separated. Therefore, bone breakage will not occur.

[0058] To prevent the cleaver from hitting the chicken leg bone too hard, the blade should not be too sharp, but rather set to be relatively blunt.

[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
