Description

Technical Field

[0001] This invention relates to the technical field of chicken processing, and in particular to an automatic chicken piece cutting machine. Background Technology

[0002] In the chicken processing industry, cutting whole chickens or large pieces of chicken into uniformly sized blocks is a prerequisite for subsequent deep processing steps such as marinating, frying, and packaging. The cutting process not only directly affects the appearance, specifications, and standardization of the final product, but also greatly influences the efficiency of subsequent processing and the added value of the product. Currently, chicken cutting operations generally adopt a step-by-step cutting method using a combination of horizontal and vertical blades. Specifically, firstly, the horizontal blade cuts the material along the conveying direction to form long strips extending along the conveying direction; then, the vertical blade cuts the strips vertically to divide them into multiple blocks, thus completing the final cutting process.

[0003] However, since the cutting direction of the vertical blade is perpendicular to the material conveying direction, the vertical blade can only complete one cutting action in each up-and-down movement cycle, and the material processing capacity of a single cutting stroke is limited. At the same time, in order to coordinate with the up-and-down reciprocating motion of the vertical blade, the material conveying must adopt an intermittent conveying method, that is, the material is conveyed forward for a certain distance and then paused until the vertical blade completes the cutting before continuing to convey forward. This intermittent slitting method is inefficient and is prone to causing equipment vibration. In addition, the existing equipment lacks effective compression and limiting mechanisms for the material before and after slitting. During and after the cutting process, the blade is prone to carrying the material off-center, resulting in uneven cut surfaces and inconsistent block sizes. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an automatic chicken nugget cutting machine, the specific technical solution of which is as follows: An automatic chicken nugget cutting machine of the present invention includes: A conveyor assembly for conveying chicken pieces to be cut includes a conveyor wheel and an arc-shaped body arranged coaxially. A portion of the outer wall of the conveyor wheel and the arc-shaped body form an arc-shaped channel for conveying the chicken pieces. The cross-cutting assembly includes several cross-cutting blades distributed around the circumference of the conveyor wheel. The cross-cutting blades cooperate with the arc-shaped body to cut the chicken meat conveyed in the arc-shaped channel into strips along the axial direction of the conveyor wheel. The vertical blade assembly includes several vertical cutting blades, which cooperate with the conveyor wheel to cut the strip-shaped chicken meat in the arc-shaped channel into pieces; The transverse cutter has several slits. When the transverse cutter moves to the area where it overlaps with the vertical cutter, the vertical cutter passes through the slits and moves relative to the transverse cutter.

[0005] Furthermore, the arc-shaped body includes an extrusion belt and two conveying rollers that drive and support the extrusion belt, as well as an arc-shaped shaping body located inside the extrusion belt. The arc-shaped shaping body cooperates with the vertical cutter to shape a portion of the extrusion belt, so that the extrusion belt and the conveying roller form an arc-shaped channel.

[0006] Furthermore, along the circumferential direction of the conveyor wheel, one end of the vertical cutter cuts the chicken meat, and the other end is provided with a thick plate, so that the distance between the chicken meat on both sides of the vertical cutter increases when it moves to the position of the thick plate.

[0007] Furthermore, the conveyor wheel includes a plurality of extrusion bodies, each of which is arranged in a one-to-one correspondence with the cross-cutting blade. The area in which the extrusion bodies move circumferentially around the axis of the conveyor wheel is divided into a slitting zone that cooperates with the extrusion belt and a rotating zone that is away from the extrusion belt. During the movement of the extrusion bodies in the slitting zone, the distance between two adjacent extrusion bodies first increases and then decreases. During the movement of the extrusion bodies in the rotating zone, the distance between two adjacent extrusion bodies remains constant.

[0008] Furthermore, the cross-cutting blade slides radially along the conveyor wheel on the extrusion body, causing the cross-cutting blade to form an outwardly extending slicing state and a retracted state in the direction of the conveyor wheel axis on the extrusion body, with the slicing state located inside the area covered by the arc-shaped channel.

[0009] Furthermore, the conveying wheel also includes a core disk and a circular rail disposed on the end face of the core disk, and the extrusion body moves on the circular rail via a support body.

[0010] Furthermore, the outer circumferential wall of the core disk is provided with an outer support surface and an inner concave surface. When the cross-cutting blade moves on the outer support surface or the inner concave surface, the cross-cutting blade switches between a cutting state and a storage state. The cross-cutting blade is supported by an elastic body, which stretches and deforms when the cross-cutting blade is in a slitting state.

[0011] Furthermore, the slitting machine also includes a drive unit that provides power for the movement of the extruded body; The drive assembly includes a guide arc plate and two opposing drive wheels, as well as a transmission chain that moves on the guide arc plate and the drive wheels. A portion of the transmission chain between the two drive wheels corresponds to the cutting zone, and a portion of the transmission chain on the guide arc plate corresponds to the rotation zone. The transmission chain drives the extrusion body to move through a prying body.

[0012] The beneficial effects of this invention are as follows: By combining the conveyor wheels and the arc-shaped body, an arc-shaped channel with a specified width is formed. This ensures that the chicken meat is constantly subjected to compression from the conveyor wheels and the arc-shaped body while being conveyed within the channel. This guarantees that the chicken meat is cut under compression, resulting in neat cross-sections of the chicken fibers and uniformly sized pieces. In addition, the use of a circulating transverse cutter and a vertical cutter set along the chicken conveying direction allows for continuous cutting of the conveyed chicken meat. This transforms the cutting method from intermittent to continuous, improving work efficiency and reducing equipment vibration. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figure 1-6 As shown, an automatic chicken nugget cutting machine of the present invention includes: The conveyor assembly, used to transport chicken pieces to be cut, includes a coaxially arranged conveyor wheel 1 and an arc-shaped body 2. A portion of the outer wall of the conveyor wheel 1 and the arc-shaped body 2 form an arc-shaped channel for conveying the chicken pieces. Specifically, the arc-shaped body 2 is fitted onto the outside of the conveyor wheel 1. The opening direction of the arc-shaped body 2 can be horizontal, inclined, or vertical, depending on the specific configuration in conjunction with the external production line. Taking a horizontal opening direction for the arc-shaped body 2 as an example, the upper and lower ends of the arc-shaped body 2 form two ports with the outer wall of the conveyor wheel 1, which are used for feeding and discharging, respectively. In addition, based on the characteristic that the conveyor wheel 1 and the arc-shaped body 2 are coaxially arranged, the width of the arc-shaped channel formed by the conveyor wheel 1 and the arc-shaped body 2 is constant at any position. When the chicken pieces enter the arc-shaped channel, the conveyor wheel 1 and the arc-shaped body 2 can always form an effective and stable squeezing effect on the chicken pieces. This effect covers both before and after the chicken pieces are cut, so that the cutting process will not cause the chicken pieces to shift. At the same time, the method of cutting the chicken pieces under the squeezing state can make the cut pieces have a regular shape, neat cross-section of chicken meat fibers, and small differences between pieces. The cross-cutting assembly includes several cross-cutting blades 3 distributed around the circumference of the conveyor wheel 1. These blades 3, in conjunction with the arc-shaped body 2, cut the chicken meat conveyed within the arc-shaped channel into strips along the axis of the conveyor wheel 1. It can be seen that the cutting edge of the cross-cutting blades 3 is along the axis of the conveyor wheel 1. The cross-cutting blades 3 can follow the conveyor wheel 1 in a circular motion as the conveyor wheel 1 rotates; that is, each cross-cutting blade 3 can circulate through the arc-shaped channel. When a cross-cutting blade 3 enters the arc-shaped channel, the cutting edge of the cross-cutting blade 3 facing the arc-shaped body 2 can interact with the arc-shaped body 2. The inner wall of body 2 is used to cut the chicken meat, and the area between two adjacent transverse cutting blades 3 can provide storage space for strips of chicken meat; optionally, the transverse cutting blades 3 can also be set on the arc-shaped body 2, in which case the cutting edge of the transverse cutting blades 3 faces the outer wall of the conveyor wheel body 1, and the transverse cutting blades 3 and the outer wall of the conveyor wheel body 1 are used to cut the chicken meat. Since the chicken meat needs to be conveyed in the arc-shaped channel, the transverse cutting blades 3 also need to have the characteristic of cyclic movement in the arc-shaped channel. This method is only an optional example and is not intended to limit the scope of protection of this invention. The vertical blade assembly includes several vertical cutting blades 5. These blades 5 cooperate with the conveyor wheel 1 to cut strips of chicken meat into pieces within an arc-shaped channel. It can be seen that the cutting edge of the vertical cutting blades 5 is oriented along the circumference of the conveyor wheel 1. Several vertical cutting blades 5 are arranged along the axis of the conveyor wheel 1. The vertical cutting blades 5 can be fixed within the arc-shaped channel, allowing the static blades 5 to cut the dynamic chicken meat. Since the chicken meat moves along the arc-shaped channel trajectory, the first point of contact between the vertical cutting blades 5 and the chicken meat is the end of the vertical cutting blade 5. Therefore, when the straight line containing the end of the vertical cutting blade 5 is along the radial direction of the conveyor wheel 1, the cutting edge of the vertical cutting blade 5 can be positioned at that end. The blade directly cuts the moving chicken. Of course, to reduce the difficulty of cutting and extend the cutting distance, the end of the vertical blade 5 can be set as a tip, and the tip contacts the inner wall of the arc-shaped body 2. The side of the vertical blade 5 facing the conveyor wheel 1 is set as the blade edge. This blade edge is an arc with a large distance, and the distance between the blade edge and the outer wall of the conveyor wheel 1 gradually decreases along the arc-shaped channel trajectory. Thus, when the chicken moves in the arc-shaped channel, the tip of the vertical blade 5 will contact the chicken first, and as the distance between the blade edge of the vertical blade 5 and the conveyor wheel 1 decreases, the depth of the vertical blade 5 cutting into the chicken gradually increases until the chicken is cut off. The transverse cutter 3 has several slits 4. When the transverse cutter 3 moves to the area where it overlaps with the vertical cutter 5, the vertical cutter 5 passes through the slits 4 and moves relative to it. It can be seen that since the transverse cutter 3 and the vertical cutter 5 process the chicken in different directions and their working areas both cover the chicken, in order to avoid the transverse cutter 3 colliding with or getting stuck with the vertical cutter 5 when it moves to the position of the vertical cutter 5, several slits 4 can be opened on the transverse cutter 3 so that each slit 4 corresponds to the vertical cutter 5. When the transverse cutter 3 passes through the area where the vertical cutter 5 is located, the vertical cutter 5 passes through the slits 4, thereby enabling the transverse cutter 3 and the vertical cutter 5 to move relative to each other. The slits 4 on the transverse cutter 3 can also guide the vertical cutter 5, preventing the vertical cutter 5 from tilting or deviating along the axis of the conveyor wheel 1. As another embodiment of the above, when the cross-cutting blade 3 is set on the arc-shaped body 2, the vertical cutting blade 5 is correspondingly set on the conveyor wheel 1. Due to the limitation of the direction of the cross-cutting blade 3, the cross-cutting blade 3 needs to be able to circulate through the arc-shaped channel. The vertical cutting blade 5 can be fixed in the arc-shaped channel or follow the conveyor wheel 1 to make circular motion. When the vertical cutting blade 5 adopts the setting method of following the circular motion of the conveyor wheel 1, the shape of the vertical cutting blade 5 can be ring-shaped. Of course, if the way the chicken is fed into the arc-shaped channel is intermittent, then the shape of the vertical cutting blade 5 can also be set to arc-shaped. In the circumferential direction of the conveyor wheel 1, one or more vertical cutting blades 5 can be set.

[0019] In use, chicken meat is fed into the arc-shaped channel through the port formed by one end of the arc-shaped body 2 and the outer wall of the conveyor wheel 1. The outer wall of the conveyor wheel 1 pushes the chicken meat to slide on the inner wall of the arc-shaped body 2, so that the chicken meat moves in the arc-shaped channel. The cross-cutting blade 3 can cut the chicken meat along the axis of the conveyor wheel 1 to form strips. Then the vertical cutting blade 5 can cut the strips of chicken meat along the circumference of the conveyor wheel 1 to form blocks, thus completing the cutting of the chicken meat. When the chicken meat moves to the port formed by the other end of the arc-shaped body 2 and the outer wall of the conveyor wheel 1, the chicken meat is automatically discharged, thus realizing the continuous cutting of the chicken meat.

[0020] In the above embodiments, in addition to using the cross-cutting blade 3 to cut the chicken into strips and then using the vertical cutting blade 5 to cut the chicken into chunks, the chicken can also be cut into strips using the vertical cutting blade 5 and then into chunks using the cross-cutting blade 3. Alternatively, the chicken can be cut into chunks simultaneously using both the cross-cutting blade 3 and the vertical cutting blade 5. The specific cutting method can be determined according to actual production needs, and will not be elaborated here.

[0021] It should be noted that, in order to increase the friction between the outer wall of the conveyor wheel 1 and the chicken, so that the chicken can move stably in the arc-shaped channel, a large number of protrusions can be provided on the outer wall of the conveyor wheel 1. Furthermore, when the cross-cutting blade 3 follows the circumferential movement of the conveyor wheel 1, the side wall of the cross-cutting blade 3 can also play the role of pushing the chicken to move.

[0022] In this embodiment, the cooperation of the conveyor wheel 1 and the arc-shaped body 2 forms an arc-shaped channel with a specified width. When the chicken is conveyed in the arc-shaped channel, it is always subjected to the squeezing action from the conveyor wheel 1 and the arc-shaped body 2, thereby ensuring that the chicken is cut under the squeezing state, so that the cross-section of the chicken fibers is neat and the chicken pieces are of uniform size. In addition, by using the circulating horizontal cutter 3 and the vertical cutter 5 set along the chicken conveying direction, the chicken in the conveying state can be continuously cut, changing the cutting method from the original intermittent to continuous, improving work efficiency and reducing equipment vibration.

[0023] As a preferred embodiment of the above, see Figure 2 The arc-shaped body 2 includes an extrusion belt 7 and two conveying rollers 6 that drive and support the extrusion belt 7, as well as an arc-shaped shaping body 8 located inside the extrusion belt 7. The arc-shaped shaping body 8 cooperates with the vertical cutter 5 to shape a portion of the extrusion belt 7, so that the extrusion belt 7 and the conveying wheel 1 form an arc-shaped channel.

[0024] In this embodiment, the conveyor roller 6 is rotatably mounted on the arc-shaped shaping body 8, and the rotational power of the conveyor roller 6 can be provided by a motor. The vertical cutter 5 is fixedly set relative to the arc-shaped shaping body 8. The outer wall of the arc-shaped shaping body 8 supports the outer part of the extrusion belt 7 away from the conveyor wheel 1, and the inner wall of the arc-shaped shaping body 8 supports the inner part of the extrusion belt 7 towards the conveyor wheel 1. This part of the extrusion belt 7 can effectively support the chicken meat based on the arc-shaped shaping body 8. That is, this part of the extrusion belt 7 can lift the chicken meat and cooperate with the horizontal cutter 3 to form a cutting mode for the chicken meat. The edge of the vertical cutter 5 away from the conveyor wheel 1 can form an outward supporting effect on this part of the extrusion belt 7, so that the extrusion belt 7 can fit against the arc-shaped shaping body 8, and the extrusion belt 7 always remains taut. The width of the arc-shaped channel between the extrusion belt 7 and the conveyor wheel 1 remains constant.

[0025] Based on the above embodiments, when the conveying roller 6 rotates, the extrusion belt 7 can be driven to slide on the arc-shaped shaping body 8, thereby enabling the part of the extrusion belt 7 that makes up the arc-shaped channel to move synchronously with the conveying wheel 1, achieving stable conveying of chicken meat and reducing the friction of the chicken meat moving on the arc-shaped body 2.

[0026] As a preferred embodiment of the above, such as Figure 2As shown, along the circumferential direction of the conveyor wheel 1, one end of the vertical cutter 5 cuts the chicken meat, and the other end is provided with a thick plate 9, so that the distance between the chicken meat on both sides of the vertical cutter 5 increases when it moves to the position of the thick plate 9.

[0027] Specifically, along the axis of the conveyor wheel 1, the thickness of the thick plate 9 is greater than the thickness of the vertical cutter 5, and the distance between two adjacent thick plates 9 is less than the distance between two adjacent vertical cutters 5. Based on this characteristic, when the vertical cutter 5 does not completely cut the chicken on both sides, the chicken on both sides of the vertical cutter 5 is still partially stuck together. The thick plate 9 can help push the chicken on both sides of the vertical cutter 5 in a direction away from each other, so that the chicken is torn apart.

[0028] In this preferred embodiment, since the distance between two adjacent thick plates 9 is smaller than the distance between two adjacent vertical cutters 5, the chicken meat is compressed and its volume is reduced when it is clamped and conveyed between the two adjacent thick plates 9 by the extrusion belt 7 and the conveyor wheel 1.

[0029] In some embodiments, to facilitate the smooth movement of chicken meat between two adjacent vertical cutters 5 to between two adjacent thick plates 9, a chamfer or a conical surface can be provided at the connection position between the vertical cutter 5 and the thick plate 9. Of course, other methods can also be used to achieve the above function. For example, the end of the vertical cutter 5 near the thick plate 9 can be tilted. While ensuring that the distance between two adjacent thick plates 9 is equal to the distance between two adjacent vertical cutters 5, the distance between the chicken meat on both sides of the thick plate 9 can also be increased by using the thick plate 9. This is also within the protection scope of the present invention. As a preferred embodiment of the above, see Figure 3-4 The conveyor wheel 1 includes several extrusion bodies 10, and each extrusion body 10 is arranged in a one-to-one correspondence with the cross-cutting blade 3. The area in which the extrusion body 10 moves circumferentially around the axis of the conveyor wheel 1 is divided into a slitting zone that cooperates with the extrusion belt 7 and a rotating zone away from the extrusion belt 7. During the movement of the extrusion body 10 in the slitting zone, the distance between two adjacent extrusion bodies 10 first increases and then decreases. During the movement of the extrusion body 10 in the rotating zone, the distance between two adjacent extrusion bodies 10 remains constant.

[0030] In this preferred embodiment, several extrusion bodies 10 are arranged in a ring around the axis of the conveyor wheel 1, and the cross-cutting blades 3 are mounted on the extrusion bodies 10. In this way, when the extrusion bodies 10 move in a circular motion around the axis of the conveyor wheel 1, the cross-cutting blades 3 move synchronously with the extrusion bodies 10, and the distance between two adjacent cross-cutting blades 3 can be adjusted synchronously by adjusting the position of the extrusion bodies 10.

[0031] Specifically, the cross-cutting blade 3 can be installed on the side wall of the extrusion body 10 away from the axis of the conveyor wheel 1, or a gap can be left between two adjacent extrusion bodies 10 to install the cross-cutting blade 3. The side wall of the extrusion body 10 away from the axis of the conveyor wheel 1 is provided with protrusion-like structures to increase the friction between the extrusion body 10 and the chicken meat. When the extrusion body 10 moves in a circular motion around the axis of the conveyor wheel 1, the extrusion body 10 can cooperate with the end of the arc-shaped body 2 to extrude and convey the chicken meat into the arc-shaped channel, and the cross-cutting blade 3 on the extrusion body 10 cuts the chicken meat. The extrusion body 10 interacts with the arc-shaped channel... When the corresponding cutting zone moves, the distance between two adjacent extrusion bodies 10 increases first. At this time, the distance between two adjacent transverse cutters 3 increases. The transverse cutter 3 that has completed the cutting will first accelerate the pushing of the strip-shaped chicken meat on it away from the chicken meat that has not been cut. This achieves the tearing and separation of the chicken meat along the cutting direction of the transverse cutter 3, avoiding the sticking of chicken meat due to incomplete cutting. After the chicken meat is completely torn and separated, the distance between two adjacent extrusion bodies 10 decreases again, so that the positional relationship between two adjacent extrusion bodies 10 returns to the normal state, which facilitates the normal movement of the extrusion body 10 in the rotation zone.

[0032] It should be noted that, as the cross-cutting blade 3 moves at accelerated speed, its cutting edge maintains its slicing effect on the chicken. Thus, when the chicken is torn, the cutting edge of the cross-cutting blade 3 can be used to completely cut the chicken.

[0033] As a preferred embodiment of the above, such as Figure 4 As shown, the cross-cutting blade 3 slides radially along the conveyor wheel 1 on the extrusion body 10, so that the cross-cutting blade 3 forms an outwardly extending cutting state and a retracted state in the direction of the axis of the conveyor wheel 1 on the extrusion body 10. The cutting state is located inside the area covered by the arc-shaped channel.

[0034] In this embodiment, when the cross-cutting blade 3 follows the extrusion body 10 in a circular motion, the cross-cutting blade 3 is in two states: a cutting state and a retracted state. The cutting state is located inside the area covered by the arc-shaped channel and corresponds to the cutting area, while the retracted state covers other areas of the cross-cutting blade 3's circular motion and corresponds to the rotation area. The area where the cutting state is located is smaller than the area covered by the arc-shaped channel, that is, the cutting state and both ends of the arc-shaped body 2 are far apart from each other. In this way, when the chicken enters the arc-shaped channel, the chicken is mainly fed by the extrusion and conveying of the chicken by the outer wall of the conveyor wheel 1 and the extrusion belt 7, which avoids the cross-cutting blade 3 extending directly out at the chicken feeding position and cutting the chicken, so that subsequent chicken cannot be fed into the arc-shaped channel. Since the thick plate 9 is set at the end of the vertical cutter 5 at the discharge position of the arc-shaped channel, and the width of the blade slit 4 on the cross-cutting blade 3 cannot allow the thick plate 9 to pass through, the cross-cutting blade 3 needs to be retracted before it moves to the discharge position to avoid the cross-cutting blade 3 and the thick plate 9 getting stuck together.

[0035] To facilitate support of the extruded body 10, as a preferred embodiment of the above, see [reference needed]. Figure 3-5The conveyor wheel 1 also includes a core disk 12 and a circular rail 13 disposed on the end face of the core disk 12. The extrusion body 10 moves on the circular rail 13 through the support body 14.

[0036] The core disc 12 is coaxially arranged with the conveyor wheel 1. The core disc 12 can provide support for the extrusion body 10 through the circular rail 13 and the support body 14, so that the extrusion body 10 can move in a circular motion around the axis of the conveyor wheel 1, ensuring that the extrusion body 10 and the extrusion belt 7 can form an arc-shaped channel and effectively cut the chicken.

[0037] As a specific example of implementation, see Figure 4-5 The outer circumferential wall of the core disk 12 is provided with an outer support surface 15 and an inner concave surface 16. When the cross-cutting blade 3 moves on the outer support surface 15 or the inner concave surface 16, the cross-cutting blade 3 switches between the cutting state and the storage state. The cross-cutting blade 3 is supported by the elastic body 11, which stretches and deforms when the cross-cutting blade 3 is in the cutting state.

[0038] In this embodiment, the diameter of the concave surface 16 is smaller than the diameter of the outer support surface 15. The outer support surface 15 and the concave surface 16 correspond to the cutting state and the storage state of the cross-cutting blade 3, respectively. When the cross-cutting blade 3 moves on the outer support surface 15, the outer support surface 15 pushes the cross-cutting blade 3 away from the axis of the conveyor wheel 1. At this time, the cross-cutting blade 3 extends out of the extrusion body 10 and cuts the chicken. When the cross-cutting blade 3 moves on the concave surface 16, the distance between the cross-cutting blade 3 and the conveyor wheel 1 shortens, and the cross-cutting blade 3 retracts on the extrusion body 10. This achieves control over the position of the cross-cutting blade 3, and this control method does not require additional power.

[0039] In addition, in order to keep the cross-cutting blade 3 in contact with the outer support surface 15 and the inner concave surface 16, an elastic body 11 can be used to provide elastic force to the cross-cutting blade 3. The elastic body 11 can be a spring, a sheet, or other structure.

[0040] It should be noted that the end of the cross-cutting blade 3 away from the axis of the conveyor wheel 1 is the cutting edge, and the end of the cross-cutting blade 3 facing the axis of the conveyor wheel 1 is used to slide in contact with the outer support surface 15 and the inner concave surface 16. In order to reduce the friction of the cross-cutting blade 3 moving on the outer support surface 15 and the inner concave surface 16, a rolling element structure such as a roller can be added to this end of the cross-cutting blade 3.

[0041] Based on the above embodiments, as one implementation method for driving the extrusion body 10 to move, see [link to relevant documentation]. Figure 3 and Figure 6 The slitting machine also includes a drive group 17, which provides power for the movement of the extrusion body 10; The drive assembly 17 includes a guide arc plate 18 and two drive wheels 19 arranged opposite to each other, as well as a transmission chain 20 that moves on the guide arc plate 18 and the drive wheels 19. The part of the transmission chain 20 between the two drive wheels 19 corresponds to the cutting area, and the part of the transmission chain 20 on the guide arc plate 18 corresponds to the rotation area. The transmission chain 20 drives the extrusion body 10 to move through the actuating body 21.

[0042] Specifically, the two drive wheels 19 are located on one side of the axis of the conveyor wheel 1, and the guide arc plate 18 is located on the other side of the axis of the conveyor wheel 1. This causes the guide arc plate 18 and the two drive wheels 19 to spread the transmission chain 20 into an arc-shaped structure composed of a straight segment and an arc segment. The straight segment is located between the two drive wheels 19, and the arc segment is located on the guide arc plate 18. The straight segment corresponds to the cutting area, and the arc segment corresponds to the rotation area. When the motor drives the drive wheels 19 and the transmission chain 20, the transmission chain 20 can push the extrusion body 10 to perform circular motion on the core disk 12 through the actuating body 21. When the extrusion body 10 moves on the arc segment of the transmission chain 20, the actuating body 21 on the transmission chain 20 performs arc motion around the axis of the conveyor wheel 1. In this motion, the distance between the actuating body 21 and the axis of the conveying wheel 1 is constant, and the extrusion body 10 moves at a constant speed. When the extrusion body 10 moves on the straight section of the transmission chain 20, the distance between the actuating body 21 and the axis of the conveying wheel 1 first decreases and then increases. Since the speed of the drive wheel 19 is constant, during the decrease, the angular velocity of the actuating body 21 relative to the circumference of the conveying wheel 1 increases, and the corresponding movement speed of the extrusion body 10 increases. During the increase, the angular velocity of the actuating body 21 relative to the circumference of the conveying wheel 1 decreases, and the corresponding movement speed of the extrusion body 10 decreases. This achieves multi-mode motion control of the extrusion body 10, which first accelerates, then decelerates, and then rotates at a constant speed.

[0043] like Figure 4 As shown, in this embodiment, a groove 22 is formed on the side wall of the support body 14 along the radial direction of the conveyor wheel 1. The end of the actuating body 21 is slidably installed in the groove 22. Thus, when the transmission chain 20 is driven, the actuating body 21 can actuate the support body 14 to perform a circular motion. The support body 14 drives the extrusion body 10 to move synchronously. The change in the distance between the actuating body 21 and the axis of the conveyor wheel 1 allows the actuating body 21 to slide in the groove 22.

[0044] In addition to the above methods, the groove 22 can be directly opened on the side wall of the extrusion body 10, and the size of the guide arc plate 18, drive wheel 19 and transmission chain 20 can be increased so that they can work with the groove 22 to drive the extrusion body 10. During the process of extrusion body 10 extruding and conveying chicken, in order to prevent the chicken from falling off from both sides of the length direction of the extrusion body 10, two baffles 23 can be set at both ends of the extrusion body 10.

[0045] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
