[0038] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0039] In this disclosure, unless otherwise specified, the use of terms such as "first" and "second" to describe various elements is not intended to limit the positional relationship, timing relationship, or importance relationship of these elements. Such terms are simply used to distinguish one element from another. In some examples, the first element and the second element may refer to the same instance of the element, and in some cases, based on the context of the description, they may also refer to different instances. In some examples, "connected" may include "directly connected" or "indirectly connected."

[0040] In this disclosure, the "vertical direction" is roughly parallel to the direction of gravity, and the "horizontal direction" is perpendicular to the "vertical direction." The terms used in the descriptions of the various examples described in this disclosure are for the purpose of describing specific examples only and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element may be one or more. In addition, the term "and / or" used in this disclosure covers any one of the listed items and all possible combinations.

[0041] In the related art, the toe clipping machine includes a die base and a toe clipping mechanism. When clipping the toes of the claw to be clipped, the staff will fix the claw to be clipped on the die base, and then the toe clipping mechanism will clip the toes of the claw to be clipped. The shape and size of the die base are fixed, but there are differences in the forms or sizes of different claws to be clipped, so that the toe clipping machine can only clip the toes of claws to be clipped of specific shapes and sizes. Since the distance moved by the toe clipping mechanism during the toe clipping process is constant, if the form or size of the claw to be clipped is greatly different from the form and size adapted by the die base, it is easy to have the problem of excessive or insufficient toe clipping, resulting in poor toe clipping quality of the claw to be clipped and low work efficiency.

[0042] To address the above-mentioned issues, the present disclosure provides a toe clipping machine, comprising a die base, a positioning mechanism, and a toe clipping mechanism. The die base is used to place a nail portion to be clipped, the positioning mechanism is used to secure the nail portion to be clipped on the die base, and the toe clipping mechanism comprises a detection device and a toe clipping knife. The toe clipping knife is used to move toward the nail of the nail portion to be clipped, which is secured to the die base. The detection device is used to detect the contact state between the toe clipping knife and the nail portion to be clipped. The toe clipping knife is further used to clip the nail portion to be clipped based on the contact state detected by the detection device.

[0043] The toe clipper provided by the embodiment of the present disclosure has a toe clipper that clips the toes of the claw to be clipped based on the result of the detection of the contact state between the toe clipper and the claw to be clipped by a detection device. That is, for different claws to be clipped, the contact state between the toe clipper and the claw to be clipped is consistent, and the toes are not clipped until the nail of the claw to be clipped is completely accommodated in the cutting edge of the toe clipper. This enables the toe clipper to better adapt to claws to be clipped of different sizes and shapes, improve the quality of toe clipping, and increase work efficiency.

[0044] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0045] FIG1 shows a schematic structural diagram of a toe clipping machine according to an exemplary embodiment of the present disclosure. Referring to FIG1 , the toe clipping machine includes a die base 10 , a positioning mechanism 20 , and a toe clipping mechanism 30 .

[0046] FIG2 shows a front view of a toe clipping machine according to an exemplary embodiment of the present disclosure. FIG3 shows a side view of a toe clipping machine according to an exemplary embodiment of the present disclosure. FIG4 shows a top view of a toe clipping machine according to an exemplary embodiment of the present disclosure. In conjunction with FIG1 to FIG4 , the mold base 10 has a working surface 11, which is configured to place the claw portion to be clipped. The working surface 11 has a preset position 111. The positioning mechanism 20 is configured to fix the claw portion to be clipped at the preset position 111 on the working surface 11. The toe clipping mechanism 30 includes a detection device (not shown in the figure) and a toe clipping knife 31. The toe clipping knife 31 is configured to move toward the nail of the claw portion to be clipped fixed at the preset position 111. The detection device is configured to detect the contact state between the toe clipping knife 31 and the claw portion to be clipped. The toe clipping knife 31 is also configured to clip the toe of the claw portion to be clipped based on the result of the detection device detecting the contact state between the toe clipping knife 31 and the claw portion to be clipped.

[0047] In the embodiment of the present disclosure, the claws to be clipped may include chicken claws and any other claws of poultry or birds. The shapes of different types of claws to be clipped vary. For different types of claws to be clipped, the shape or size of the mold base 10 can be changed so that the preset position 111 of the mold base 10 can be used to place the claws of the same type that need to be clipped. For the convenience of describing the embodiment of the present disclosure, the following explanations are all described using chicken claws as an example. It is understood that the toe clipping machine in the embodiment of the present disclosure can also be used to clip the claws of other poultry.

[0048] In the disclosed embodiment, the mold base 10 is used to place chicken feet, and the working surface 11 is the side of the mold base 10 facing the positioning mechanism 20 .

[0049] In the disclosed embodiment, when toe clipping is not in progress, a certain distance exists between the mold base 10 and the positioning mechanism 20, ensuring that the working surface 11 on the mold base 10 is unobstructed and that the chicken claw can be placed in the preset position 111. Furthermore, when toe clipping is not in progress, a certain distance exists between the mold base 10 and the toe clipping knife 31, facilitating placement of the chicken claw while reducing the possibility of the toe clipping knife 31 scratching the worker. When toe clipping is not in progress, the relative positions of the mold base 10 and the positioning mechanism 20 are fixed, and the position of the preset position 111 on the working surface 11 is also fixed. Thus, when the positioning mechanism 20 positions the chicken claw placed in the preset position 111, the positioning mechanism 20 and the mold base 10 can be brought close to each other, eliminating the need for additional adjustments to the positions of the mold base 10 and the positioning mechanism 20 based on the placement of the chicken claw. For example, the positioning mechanism 20 and the mold base 10 can be brought close to each other by controlling the positioning mechanism 20 to move toward the mold base 10, controlling the mold base 10 to move toward the positioning mechanism 20, or controlling both the positioning mechanism 20 and the mold base 10 to move toward each other.

[0050] In the embodiment of the present disclosure, the toe clipper 31 may provide a thrust to the chicken claw during toe clipping. The positioning mechanism 20 applies pressure to the chicken claw at the preset position 111 to position the chicken claw and secure it to the mold base 10. Even when the toe clipper 31 applies a thrust to the chicken claw, the chicken claw does not move, thereby enabling the toe clipping process to proceed smoothly. The detection device is not shown in the drawings of the present disclosure.

[0051] Exemplarily, the detection device may detect the contact state between the toe clipper 31 and the claw to be clipped, including the resistance encountered by the toe clipper 31 when contacting the claw to be clipped during movement, or determine whether the toe clipper 31 has contacted the claw to be clipped by image detection.

[0052] It should be noted that the toes of the chicken claw mentioned in the embodiment of the present disclosure are the four branches of the chicken claw, and the toenail is the plate-like structure at the front end of the toe. The toe clipper in the embodiment of the present disclosure is used to cut the toenail of the chicken claw.

[0053] When using the toe clipping machine provided by the embodiment of the present invention, the chicken claw is placed on the preset position 111, and then the positioning mechanism 20 fixes the chicken claw. After the chicken claw is fixed, the toe clipper 31 moves toward the nail of the chicken claw fixed at the preset position 111, and the nail of the chicken claw is facing the toe clipper 31. During the movement of the toe clipper 31, the contact state between the toe clipper 31 and the claw to be clipped will change. The detection device can detect the contact state between the toe clipper 31 and the claw to be clipped, so that the toe clipper can obtain the contact state between the toe clipper 31 and the claw to be clipped according to the feedback of the detection device. The contact state can exemplarily include a no-contact state, a micro-contact state, a sufficient contact state, and the like. The no-contact state means that there is still a distance between the toe clipper and the toe to be clipped and there is no physical contact, and the toe to be clipped cannot be clipped by the toe clipper; the micro-contact state means that the toe clipper and the toe to be clipped begin to contact but the degree of contact is not enough. At this time, if the toe is clipped, the quality of the toe clipping will be affected; the sufficient contact state means that the overlapping part of the toe clipper and the toe to be clipped is sufficient. When the toe clipping knife 31 overlaps enough with the toenails of the chicken claws, the toes of the chicken claws can be clipped. For chicken claws of small size, the distance that the toe clipping knife 31 moves will increase, and for chicken claws of large size, the distance that the toe clipping knife 31 moves will decrease. The toe clipping knife provided in the embodiment of the present disclosure clips the toes of the chicken claws according to the contact state between the toe clipping knife and the claw part to be clipped during the movement process, that is, for different chicken claws, the toe clipping knife 31 can move different distances according to the shape or size of the chicken claws, until the toe clipping knife 31 overlaps enough with the toenails of the chicken claws (that is, sufficient contact state) and then clips the toes, reducing the problem of insufficient or excessive toe clipping, so that the toe clipping machine can better adapt to chicken claws of different sizes and shapes, improve the toe clipping quality, and have higher work efficiency.

[0054] For example, when the detection device detects the resistance encountered by the toe clipper 31 during its movement, the toe clipper 31 will contact the toenail of the chicken claw during its movement, so that the toe clipper 31 encounters resistance during its movement. As the resistance encountered by the toe clipper 31 increases, it indicates that the overlapping portion between the toe clipper 31 and the toenail of the chicken claw increases. When the resistance encountered by the toe clipper 31 reaches a preset value, it indicates that the overlapping portion between the toe clipper 31 and the toenail of the chicken claw is sufficient, and the toenail of the claw to be clipped is completely accommodated in the cutting edge of the toe clipper 31, and the chicken claw can be clipped.

[0055] According to some embodiments of the present disclosure, the positioning mechanism 20 is configured to apply pressure to the chicken paw placed at the preset position 111 to fix and flatten the chicken paw.

[0056] Chicken claws are not always flat in their natural state and have a certain curvature. In the embodiment of the present disclosure, applying pressure to the claws can both fix the claws and flatten them. The flattened claws have a larger contact area with the positioning mechanism 20, resulting in a better fixation effect. Furthermore, the flattened claws have less morphological variation, and the orientations of the toes are generally the same. This makes it easier for the toe clipper 31 to contact the toenails when moving in a predetermined direction, thereby reducing toe clipping time and improving toe clipping efficiency.

[0057] At the same time, after the chicken claws are flattened, the morphological differences of the chicken claws are reduced, so the error of the toe cutting knife 31 when cutting the chicken claws will be smaller, further improving the toe cutting effect.

[0058] According to some embodiments of the present disclosure, in combination with Figures 1 to 4, the positioning mechanism 20 includes a toe positioning assembly 21, which includes a plurality of pressing plates 211 arranged side by side, and the plurality of pressing plates 211 are configured to apply pressure to the toes of the chicken claw to fix and flatten the toes.

[0059] Exemplarily, the plurality of pressing sheets 211 are all arranged along the vertical direction G.

[0060] In the embodiment of the present disclosure, the toe positioning assembly 21 is used to position the toes of the chicken claw. The toes of the chicken claw also have a certain curvature. Flattening the toes of the chicken claw makes it easier to fix the chicken claw. Since the toes of the chicken claw are of different lengths, the length of the chicken claw positioned by the toe positioning assembly 21 can be adjusted by changing the amount of pressure plate 211 pressed on the chicken claw, so that the toe positioning assembly 21 can adapt to different chicken claws.

[0061] In an embodiment of the present disclosure, the number of pressing tablets 211 can be set according to demand. For example, the number of pressing tablets 211 is greater than or equal to 5 and less than or equal to 15.

[0062] In other embodiments of the present disclosure, the positioning mechanism may include a positioning block, and the positioning block may be controlled to apply pressure to the chicken claw to flatten and fix the chicken claw.

[0063] According to some embodiments of the present disclosure, in combination with Figures 1 to 4, a plurality of pressing plates 211 have a positioning portion 2111 on one side close to the mold base 10. The positioning portion 2111 is configured to correspond to the position of the toes of the chicken claw when the pressing plate 211 applies pressure to the toes of the chicken claw, so that the toes are fixed in the positioning portion 2111.

[0064] In an embodiment of the present disclosure, a positioning portion 2111 is provided on the pressing sheet 211 so that the toes of the chicken claw can be fixed in the positioning portion 2111 , further improving the positioning effect of the toe positioning assembly 21 on the toes of the chicken claw.

[0065] Illustratively, the positioning portion 2111 may include a positioning notch on the pressing sheet 211 .

[0066] According to some embodiments of the present disclosure, the positioning mechanism 20 includes a plurality of toe positioning components 21 corresponding one-to-one to the plurality of toes of the chicken claw, and each toe positioning component 21 is configured to apply pressure to the corresponding toe through a plurality of pressing plates 211 .

[0067] In the disclosed embodiment, the multiple toes of the chicken claw are positioned respectively by corresponding toe positioning components 21, and each toe is positioned and controlled separately without affecting each other, which is more convenient to control.

[0068] According to some embodiments of the present disclosure, in combination with Figures 1 to 4, the toe positioning assembly 21 includes a support member 212, multiple pressing plates 211 have through holes 2112, the support member 212 passes through the through holes 2112 of the multiple pressing plates 211, and the multiple pressing plates 211 are arranged on the support member 212.

[0069] Illustratively, the support member 212 may include a support rod.

[0070] In the embodiment of the present disclosure, the support member 212 can be controlled to move in a direction away from or toward the chicken claw, so that the pressing plate 211 provided on the support member 212 can be moved in a direction away from or toward the chicken claw. When the pressing plate 211 moves in a direction away from the chicken claw, the toe positioning assembly 21 releases the positioning of the toes; when the pressing plate 211 moves in a direction toward the chicken claw, the pressing plate 211 presses on the toes of the chicken claw, thereby achieving the positioning of the toes by the toe positioning assembly 21.

[0071] According to some embodiments of the present disclosure, the plurality of pressing pieces 211 are configured to apply pressure to the toes of the chicken claw under the action of its own weight.

[0072] Since the plurality of pressing sheets 211 are provided on the support member 212, the pressing sheets 211 can be pressed on the toes of the chicken claw under the action of their own weight by setting the support member 212 in an appropriate position, without the need for an additional pressure device, which is more convenient. At the same time, the support member 212 passes through the through holes 2112 of the plurality of pressing sheets 211, so that the pressing sheets 211 will not fall over.

[0073] Figure 5 shows a schematic diagram of a pressing plate and support member according to an embodiment of the present disclosure. Referring to Figure 5 , according to some embodiments of the present disclosure, the length L of the through-holes 2112 on the multiple pressing plates 211 increases as the toe clipper 31 moves toward the nail of a chicken claw fixed at a predetermined position 111. For example, the length direction of the through-holes 2112 is parallel to the vertical direction G. The pressing plate and support member shown in Figure 5 are for illustrative purposes only.

[0074] In the embodiment of the present disclosure, the direction X in which the toe clippers 31 move toward the nail of the chicken paw fixed at the preset position 111 can be understood as the direction in which the toe clippers 31 move from away from the chicken paw to closer to the chicken paw. Different toe clippers 31 move in different directions X when clipping different toenails of the chicken paw. Referring to FIG. 4 , three toe clippers 31 (not shown in FIG. 4 ) are used to clip the nails of three toes of the chicken paw, respectively, and the directions X in which the three toe clippers 31 move are different.

[0075] In the embodiment of the present disclosure, during the toe clipping process, the toe clipper 31 moves toward the direction of the toenail of the chicken claw fixed at the preset position 111. At this time, the pressing plate 211 is pressed on the toe of the chicken claw. In order to enable the toe clipper 31 to contact the toe of the chicken claw and cut the toenail on the toe, and avoid the pressing plate 211 affecting the movement of the toe clipper 31, the support member 212 can be controlled to move in the direction away from the chicken claw. The support member 212 drives the pressing plate 211 to move in the direction away from the chicken claw. Since the lengths of the through holes 2112 on the multiple pressing plates 211 increase successively in the direction X in which the toe clipper 31 moves toward the toenail of the chicken claw fixed at the preset position 111, the pressing plate 211 facing the toe clipper 31 first moves in the direction away from the chicken claw. This not only avoids the pressing plate 211 affecting the movement of the toe clipper 31, but also some of the pressing plates 211 are pressed on the toe of the chicken claw to fix the chicken claw to avoid the toe clipper 31 pushing the chicken claw to move. As the toe clipper 31 continues to move toward the chicken's claw, the support member 212 continues to drive the pressing plate 211 away from the chicken's claw. This causes the pressing plates 211 to sequentially move away from the chicken's claw in the direction X in which the toe clipper 31 moves toward the nail of the chicken's claw fixed at the preset position 111, until the toe clipper 31 contacts the nail. After toe clipping is completed, the pressing plates 211 are released from their position on the toe, and the clipped chicken's claw can be removed.

[0076] According to some embodiments of the present disclosure, the support member 212 is also configured to move in a direction away from the working surface 11 of the mold base 10 in response to the distance between the toe clipper 31 and the pressing plate 211 being less than a preset distance value, so as to drive the pressing plate 211 among the multiple pressing plates 211 whose distance from the toe clipper 31 is less than the preset distance value to move, thereby releasing the pressure on the toes to be clipped.

[0077] In the embodiment of the present disclosure, when the distance between the toe clipper 31 and the pressing plate 211 is less than a preset distance value, indicating that the toe clipper 31 is about to contact the pressing plate 211, the pressing plate 211 can be lifted to prevent the pressing plate 211 from affecting the movement of the toe clipper 31. By controlling the support member 212 to move toward the side away from the mold base 10, multiple pressing plates 211 are lifted in sequence, and the toe clipper 31 can continue to move forward until the toe clipper 31 contacts the chicken claw's nail, allowing the toe clipper 31 to clip the chicken claw more accurately.

[0078] For example, when the toe clipping machine is not clipping toes, the distance between the toe clipping knife 31 and the pressing plate 211 is certain. The total distance moved by the toe clipping knife 31 can be determined based on the speed and time of the movement of the toe clipping knife 31, and then the distance between the toe clipping knife 31 and the pressing plate 211 during the movement can be determined.

[0079] For example, the moving speeds of the toe clipper 31 and the support 212 can be controlled so that the toe clipper 31 does not contact the pressing sheet 211 during the process of the toe clipper 31 moving toward the nail of the chicken claw.

[0080] According to some embodiments of the present disclosure, in conjunction with FIG. 1 to FIG. 4 , the toe trimming machine further includes a first motor 70 , which drives the support member 212 to move, thereby driving the pressing plate 211 to move.

[0081] In some embodiments of the present disclosure, the support members 212 corresponding to the two toes on the left and right sides of the three front toes of the chicken claw can be controlled by the same first motor 70, and the support members 212 corresponding to the middle toe of the three front toes of the chicken claw can be controlled by another first motor 70, or the three support members 212 are driven separately using different first motors 70.

[0082] According to some embodiments of the present disclosure, the positioning mechanism 20 also includes a claw surface positioning assembly 22, which includes a driving unit 221 and a pressure piece 222. The driving unit 221 is configured to drive the pressure piece 222 to apply pressure to the chicken claw placed at the preset position 111 to fix the chicken claw at the preset position 111, and the pressure piece 222 corresponds to the claw surface position of the chicken claw.

[0083] For example, the pressure applying member 222 may include a pressure plate.

[0084] In the embodiment of the present disclosure, a claw surface positioning component 22 is provided to position the claw surface of the chicken claw, and at the same time, the claw surface of the chicken claw can be flattened, making the chicken claw flatter, increasing the contact area between the chicken claw and the working surface 11, and increasing the fixing effect of the chicken claw. At the same time, the difference in the shape of the chicken claw after flattening is smaller, which can further improve the toe clipping effect.

[0085] According to some embodiments of the present disclosure, FIG6 shows a schematic diagram of a partial structure of a mold base according to an exemplary embodiment of the present disclosure. FIG7 shows a top view of a partial structure of a mold base according to an exemplary embodiment of the present disclosure. FIG8 shows a side view of a partial structure of a mold base according to an exemplary embodiment of the present disclosure. In conjunction with FIG6 to FIG8 , a preset position 111 on the working surface 11 is provided with a receiving groove 112, and the receiving groove 112 is used to receive the three front toes and the claw surface of the chicken claw. The mold base 10 also has a receiving hole 12 that passes through the working surface 11, and the receiving hole 12 is used to receive the rear toes of the chicken claw.

[0086] Because the position of the hind toes differs between left and right chicken claws, the prior art requires five positioning positions on the mold base to accommodate both left and right chicken claws, making the mold base structure more complex. Furthermore, workers must choose the placement of the claws based on the left and right claws, which increases toe clipping time and reduces work efficiency.

[0087] In the embodiment of the present disclosure, due to the specific shape of the chicken claw, the hind toe of the chicken claw can be placed downward, so that the hind toe of the chicken claw is located in the receiving hole 12, and the three front toes and the claw surface of the chicken claw are located in the receiving groove 112. In this way, both the left and right chicken claws can be placed in the mold base 10, and four positioning positions can be set to achieve the fixation of different chicken claws. Compared with the mold bases in the related art, the mold base 10 provided by the embodiment of the present disclosure is simpler. In addition, the placement method of the left and right chicken claws is the same, and there is no need to select the placement position of the chicken claws, which reduces the time of toe clipping and improves work efficiency.

[0088] Exemplarily, the shape of the receiving groove 112 is the same as the shape of the three front toes of the chicken claw after being flattened, so that the three front toes of the chicken claw can be separated for toe clipping.

[0089] In some exemplary embodiments, as shown in Figures 1 and 8, the positioning mechanism 20 may include a toe positioning assembly 21 corresponding one-to-one to the accommodating groove 112, and the toe positioning assembly 21 includes a plurality of pressing plates 211 arranged side by side, and the plurality of pressing plates 211 are configured to apply pressure to the toes of the chicken claw placed in the corresponding accommodating groove 112 to fix and flatten the toes.

[0090] According to some embodiments of the present disclosure, in combination with Figures 3 and 8, the toe trimming machine further includes a guide plate 40 provided on the back side of the mold base 10 away from the working surface 11, and the guide plate 40 is configured to position the hind toes of the chicken claw placed in the accommodating hole 12.

[0091] In the embodiment of the present disclosure, the hind toes of the chicken claw are positioned by the guide plate 40, so that the difference in the shape of the fixed chicken claw is smaller, which can further improve the toe clipping effect.

[0092] According to some embodiments of the present disclosure, in combination with Figures 1 to 4, the toe trimming machine also includes a lifting mechanism 50, which is configured to control the mold base 10 to move toward the positioning mechanism 20 when the mold base 10 is located below the positioning mechanism 20, and to control the mold base 10 to move away from the positioning mechanism 20 after the chicken claws have completed toe trimming.

[0093] During toe clipping, the mold base 10 and positioning mechanism 20 move closer to each other, allowing the positioning mechanism 20 to press against the chicken claw located on the mold base 10 to position the chicken claw. After toe clipping is complete, the mold base 10 and positioning mechanism 20 move away from each other, making it easier to remove the chicken claw. In the disclosed embodiment, the volume and weight of the positioning mechanism 20 are larger than those of the mold base 10. During toe clipping, the lifting mechanism 50 controls the mold base 10 to move toward the positioning mechanism 20, thereby controlling the movement of the smaller and heavier mold base 10, which is more convenient.

[0094] In an embodiment of the present disclosure, during the toe clipping process, the three front toes of the chicken claw can be fixed by the positioning mechanism 20 , and the rear toes of the chicken claw can be fixed by the guide plate 40 and the accommodating hole 12 .

[0095] In the embodiment of the present disclosure, referring to Figures 1 to 4 , the toe clipping mechanism 30 further includes a slider 32 and a guide rail 33. A toe clipper 31 for clipping the nails of the chicken's three front toes can be fixed to the slider 32. The slider 32 is slidably connected to the guide rail 33. A second motor 80 controls the movement of the slider 32 on the guide rail 33, thereby controlling the movement of the toe clipper 31. The toe clipper 31 for clipping the nails of the chicken's hind toes can be driven by a pneumatic cylinder.

[0096] In some embodiments of the present disclosure, different toe clippers 31 may be controlled by different second motors 80 , respectively.

[0097] According to some embodiments of the present disclosure, the toe cutting knife 31 corresponding to the hind toes of the chicken claw is driven by a cylinder or a motor.

[0098] In an embodiment of the present disclosure, the detection device is configured to detect the resistance encountered by the toe clipper 31 during its movement. The toe clipping mechanism 30 includes a driving member, which is configured to drive the toe clipper 31 to move. The detection device is configured to detect at least one of the voltage value, current value and pressure value of the driving member to determine the change in resistance encountered by the toe clipper 31 during its movement.

[0099] For example, taking the current value as an example, when the toe clipper 31 is not in contact with the chicken claw, the current value of the driving member is certain. When the toe clipper 31 is in contact with the chicken claw, the resistance encountered by the toe clipper 31 during movement will become greater, and the current value of the driving member will also increase. The change in resistance encountered by the toe clipper 31 during movement can be determined based on the change in the current value of the driving member. When the current value of the driving member increases to the preset current value, it indicates that the toe clipper 31 is in sufficient contact with the chicken claw.

[0100] Exemplarily, the driving member includes a second motor 80 and a cylinder.

[0101] In an embodiment of the present disclosure, a toe clipper 31 is used to clip the nails of the three front toes of a chicken paw. The detection device can determine the change in resistance encountered by the toe clipper 31 during movement by detecting the voltage value or current value of the second motor 80.

[0102] In an embodiment of the present disclosure, a toe clipper 31 is used to clip the nails of the hind toes of a chicken paw. The detection device can determine the change in resistance encountered by the toe clipper 31 during movement by detecting the pneumatic pressure of the cylinder.

[0103] According to some embodiments of the present disclosure, the lifting mechanism 50 includes a lifting cylinder 51 located on a side of the mold base 10 away from the positioning mechanism 20 .

[0104] In the embodiment of the present disclosure, the lifting cylinder 51 is a relatively common component for controlling the movement of the mold base 10, which makes the structure of the toe trimming machine simpler.

[0105] According to some embodiments of the present disclosure, in combination with FIG. 1 to FIG. 4 , the toe clipping machine further includes an ejection mechanism 60 , which is configured to release the chicken claw from being fixed at a preset position 111 after toe clipping is completed.

[0106] After the toe clipping is completed, the chicken claw is taken out, and the next chicken claw is conveniently clipped. In the disclosed embodiment, the ejection mechanism 60 releases the fixed positioning of the chicken claw after the toe clipping is completed, making it easier to take out the chicken claw after the toe clipping is completed.

[0107] According to some embodiments of the present disclosure, referring to FIG7 , the mold base 10 further has an ejection hole 13 penetrating the working surface 11 for placing the chicken claw; in combination with FIG1 to FIG4 , the ejection mechanism 60 includes an ejection cylinder 61 and an ejection rod 62 located on the side of the mold base 10 away from the positioning mechanism 20. The ejection cylinder 61 is configured to extend the ejection rod 62 into the ejection hole 13 and act on the chicken claw fixed at the preset position 111 after the toe clipping is completed, so as to release the fixed positioning of the chicken claw at the preset position 111.

[0108] In the embodiment of the present disclosure, since the chicken claw is fixed to the working surface 11 of the mold base 10, if the chicken claw is stuck in the receiving groove 112, it is difficult to directly remove the chicken claw. After the toe clipping of the chicken claw is completed, the ejection cylinder 61 controls the ejection rod 62 to move from the ejection hole 13 toward the chicken claw and act on the chicken claw fixed in the preset position 111, giving the chicken claw a thrust, so that the chicken claw stuck in the receiving groove 112 is pushed out, making it easier to remove the chicken claw.

[0109] According to some embodiments of the present disclosure, the moving direction V of the toe clipper 31 toward the nail of the chicken claw fixed at the preset position 111 is parallel to the working surface 11. FIG9 shows a schematic structural diagram of the toe clipper according to an exemplary embodiment of the present disclosure. FIG10 shows a front view of the toe clipper according to an exemplary embodiment of the present disclosure. Referring to FIG9 and FIG10, the toe clipper 31 includes a toe clipper body 311 and a blade 312 located at the front end of the toe clipper body 311. The toe clipper body 311 can be fixed on a slider 32 (not shown in FIG9 and FIG10). The angle between the extending direction U of the blade 312 of the toe clipper 31 and the moving direction V of the toe clipper 31 toward the nail of the chicken claw fixed at the preset position 111 is an acute angle, and the blade 312 of the toe clipper 31 is inclined toward the side of the working surface 11 where the chicken claw is placed.

[0110] The nail of a chicken's claw is located on the upper side of the toe. During the process of clipping the chicken's claw, the desired effect is to cut the nail while cutting as little chicken's claw meat as possible. In the embodiment of the present disclosure, the blade 312 of the toe clipper 31 is made into an inclined blade, and the blade 312 is inclined toward the side of the working surface 11 where the chicken's claw is placed. This allows the blade 312 of the toe clipper 31 to match the nail of the chicken's claw and to grip the nail of the chicken's claw. This allows the nail of the chicken's claw to be cut without cutting off too much chicken's claw meat, which would be wasted.

[0111] Another aspect of the present disclosure provides a toe clipping device, which may be the toe clipping machine of any one of the above embodiments.

[0112] In some embodiments of the present disclosure, the toe trimming device also includes a driving mechanism, which is configured to drive multiple mold bases 10 to move in sequence to a position opposite to the positioning mechanism 20, and trim the claws to be trimmed placed on the multiple mold bases 10 through the toe trimming mechanism 30.

[0113] In an embodiment of the present disclosure, the driving mechanism drives the mold base 10 to move to a position opposite to the positioning mechanism 20. The positioning mechanism 20 fixes the chicken claws on the mold base 10 moved thereunder, and then the toe trimming mechanism 30 trims the chicken claws. After the toes of the chicken claws are trimmed, the driving mechanism drives the mold base 10 to move away, which improves work efficiency.

[0114] FIG11 is a schematic structural diagram of a toe clipping device according to an exemplary embodiment of the present disclosure. FIG12 is a front view of a toe clipping device according to an exemplary embodiment of the present disclosure. FIG13 is a top view of a toe clipping device according to an exemplary embodiment of the present disclosure. FIG14 is a side view of a toe clipping device according to an exemplary embodiment of the present disclosure. In conjunction with FIG11 and FIG14 , the toe clipping device further comprises an annular track 120, on which a plurality of mold bases 10 are spaced apart, and a driving mechanism is configured to drive the plurality of mold bases 10 to move in sequence along the annular track to a position opposite to the positioning mechanism 20.

[0115] In the embodiment of the present disclosure, the annular track 120 drives multiple mold bases 10 to move. When the mold base 10 moves to a position opposite to the positioning mechanism 20, the positioning mechanism 20 fixes the chicken claws on the mold base 10 moved below it, and then the toe trimming mechanism 30 trims the chicken claws. After the toes of the chicken claws are trimmed, the mold base 10 moves again, waiting for the next mold base 10 to move to a position opposite to the positioning mechanism 20 for toe trimming, thereby achieving continuous toe trimming and higher work efficiency.

[0116] In an embodiment of the present disclosure, referring to Figures 11 to 14, a toe clipping device may include a positioning mechanism 20 and a toe clipping mechanism 30. During the toe clipping process, a plurality of mold bases 10 are sequentially moved to positions relative to the positioning mechanism 20, that is, the toe clipping work of one chicken claw is performed each time. Such a toe clipping device is simpler.

[0117] In other embodiments of the present disclosure, a toe-trimming device may include multiple positioning mechanisms 20 and multiple corresponding toe-trimming mechanisms 30. The circular track 120 drives multiple die holders 10 to move below their corresponding positioning mechanisms 20. The multiple positioning mechanisms 20 then position the chicken feet on their corresponding die holders 10, and the toe-trimming mechanisms 30 perform toe-trimming. This allows for multiple toe-trimming operations at once, resulting in higher efficiency.

[0118] In some embodiments of the present disclosure, the annular track 120 may include a chain, a sprocket, a reducer, and a motor. A plurality of mold bases 10 are fixed on the chain, and a driving mechanism drives the reducer to drive the sprocket to drive the mold base 10 to move.

[0119] Illustratively, the driving mechanism may include a motor.

[0120] For example, after the toe-trimmed chicken feet are ejected by the ejection mechanism 60, the die base 10 rotates downward, and the chicken feet fall directly from the die base 10 due to gravity, thereby achieving continuous toe trimming of the chicken feet with higher efficiency. For example, the chicken feet can fall to the material receiving area.

[0121] In an embodiment of the present disclosure, in conjunction with FIG. 11 and FIG. 14 , the toe clipping machine may further include a baffle 90 , which is located on a side of the pressing plate 211 away from the first motor 70 , and is used to block toenails flying during the toe clipping process.

[0122] For example, in combination with Figures 11 and 14, the toe trimming machine can also include a fixed table 100, the positioning mechanism 20, the toe trimming mechanism 30, the first motor 70, the second motor 80 and the chain can all be fixed on the fixed table 100, and the lifting mechanism 50, the ejection mechanism 60 and the material receiving area can be arranged in the fixed table 100.

[0123] Exemplarily, in conjunction with FIG11 and FIG14 , the toe clipping machine may further include a protective cover 110 , and the positioning mechanism 20 , the toe clipping mechanism 30 , the first motor 70 and the second motor 80 are all housed in the protective cover 110 to protect them.

[0124] Figures 11 to 14 illustrate a toe clipping device according to an embodiment of the present disclosure. In other embodiments of the present disclosure, Figure 15 illustrates a structural diagram of the mold base and locking mechanism in a toe clipping device according to another exemplary embodiment of the present disclosure. Figure 16 illustrates a structural diagram of the mold base and locking mechanism in a toe clipping device according to another exemplary embodiment of the present disclosure from another perspective. Figure 17 illustrates a top view of the mold base and locking mechanism in a toe clipping device according to another exemplary embodiment of the present disclosure. Referring to Figures 15 to 17, the accommodating hole 12 may extend through a side surface 102 of the mold base 10, with the side surface 102 adjacent to the working surface 11.

[0125] In the embodiment of the present disclosure, the receiving hole 12 passes through the side surface 102 of the mold base 10. This can be understood as the receiving hole 12 passing through the working surface 11 and the other side opposite the working surface 11 of the mold base 10, and the receiving hole 12 is connected to the outside of the mold base 10 at the side surface 102 of the receiving hole 12. It can also be understood that the receiving hole 12 is a through groove, so that the hind toe of the chicken claw located outside the mold base 10 can enter the receiving hole 12 through the side surface 102 of the receiving hole 12. The receiving hole 12 passes through the side surface 102 of the mold base 10, so the hind toe can be directly removed from the receiving hole 12 through the side surface 102 of the mold base 10, which is simple to operate and more efficient.

[0126] For example, the receiving hole 12 may penetrate the bottom surface of the receiving groove 112 along the vertical direction G.

[0127] In an embodiment of the present disclosure, referring to Figures 15 to 17 , the toe trimmer further includes a locking mechanism 130. The locking mechanism 130 includes a driving member 131 and a locking member 132.

[0128] Referring to Figures 15 to 17, the driving member 131 is connected to the locking member 132, and the driving member 131 is configured to drive the locking member 132 to move to press against the rear toe of the claw to be cut so that the claw to be cut is fixed in the accommodating hole 12, or to push the rear toe of the claw to be cut so that the claw to be cut is detached from the side 102 of the mold base 10.

[0129] In some embodiments of the present disclosure, the driving member 131 may be a motor.

[0130] In the embodiment of the present disclosure, the locking member 132 may move to the bottom or top of the accommodating hole 12 during the movement process, and may also move out from the bottom or top of the mold base 10 .

[0131] In an embodiment of the present disclosure, after the hind toes of the chicken claw are placed in the locking member 132, the driving member 131 drives the locking member 132 to move to push the hind toes of the chicken claw, so that the hind toes of the chicken claw are fixed in the accommodating hole 12 of the mold base 10, and then the toe cutting mechanism 30 cuts the toes of the chicken claw. After the toe cutting is completed, the driving member 131 drives the locking member 132 to move to push the hind toes of the chicken claw, so that the chicken claw can be detached from the side 102 of the mold base 10. There is no need for the staff to remove the chicken claw from the mold base 10, which is simple to work and efficient.

[0132] In some embodiments of the present disclosure, the driving member 131 can drive the locking member 132 to rotate. The output shaft 1311 of the driving member 131 is connected to the locking member 132 , and the rotation axis of the locking member 132 is parallel to the central axis of the accommodating hole 12 .

[0133] For example, the locking member 132 may be a rotating piece. The rotating piece is thin so that the rotating piece can be rotated to the bottom or top of the accommodating hole 12 without taking up too much space of the mold base 10, which is conducive to the miniaturization design of the toe trimming machine.

[0134] In some embodiments of the present disclosure, when the toe trimmer is in normal use, the output shaft 1311 of the driving member 131 extends along the vertical direction G, and the center axis of the accommodating hole 12 also extends along the vertical direction G. Then the rotation direction of the locking member 132 is roughly parallel to the horizontal plane, wherein the horizontal plane is perpendicular to the vertical direction G, and the moving direction of the locking member 132 is the direction of the moving speed of the locking member 132 at any time.

[0135] In some embodiments of the present disclosure, the locking mechanism 130 further includes a detector configured to detect whether there is a rear toe of the claw portion to be trimmed in the locking member 132, and the driving member 131 is configured to drive the locking member 132 to move based on the detection result of the detector. The detector is located inside the toe trimmer and is not shown in the drawings of the embodiments of the present disclosure.

[0136] In the embodiment of the present disclosure, a detector is used to detect whether there is a hind toe of the claw to be trimmed in the locking member 132, and the driving member 131 can drive the locking member 132 to move based on the detection result of the detector, thereby eliminating the need for manual operation of the driving member 131, making it more convenient and quick, and increasing work efficiency.

[0137] In some embodiments of the present disclosure, the locking member 132 is located on the other side of the mold base 10 opposite the side where the working surface 11 is located. That is, when the toe trimmer is operating normally, the locking member 132 can move below the receiving hole 12 or move out from below the mold base 10 during movement, thereby reducing the impact of the locking member 132 on the working surface 11 of the mold base 10 during movement.

[0138] In some embodiments of the present disclosure, referring to Figures 15 to 17, the locking member 132 has a placement slot 1321, which is configured to correspond to the position of the accommodating hole 12 so that the portion of the rear toe of the claw to be cut can be located in the placement slot 1321.

[0139] In the embodiment of the present disclosure, when toe clipping is not in progress, the placement slot 1321 and the receiving hole 12 are offset, allowing the hind toe of the chicken claw to be placed in the placement slot 1321. When toe clipping is in progress, the placement slot 1321 is connected to the receiving hole 12, allowing the hind toe of the chicken claw to be fixed in the receiving hole 12.

[0140] In the embodiment of the present disclosure, the placement slot 1321 passes through two opposite surfaces of the locking member 132, and the opening of the placement slot 1321 passes through one of the side surfaces of the locking member 132, so that the hind toes of the chicken claw can be placed in the placement slot 1321. When the locking member 132 is removed from the mold base 10 to remove the chicken claw from the mold base 10, the chicken claw can be directly removed from the opening of the placement slot 1321. For example, the chicken claw can be directly removed from the opening of the placement slot 1321 and placed in the storage device, which is more convenient.

[0141] In an embodiment of the present disclosure, when the hind toe of the chicken claw is placed in the placement groove 1321, the chicken claw will generate pressure on the locking piece 132. The detector can determine whether the hind toe of the chicken claw is in the placement groove 1321 by detecting the force condition of the locking piece 132.

[0142] In some embodiments of the present disclosure, referring to Figures 15 and 16 , the locking mechanism 130 further includes a blocking member 133 disposed on the locking member 132. The blocking member 133 is located on the side of the placement slot 1321 adjacent to the receiving hole 12. The mold base 10 further includes a sliding channel 14, one end of which communicates with the receiving hole 12 and the other end of which extends into the mold base 10. When the driving member 131 drives the locking member 132 to move, at least a portion of the blocking member 133 is located within and slides along the sliding channel 14.

[0143] Exemplarily, the sliding track defined by the sliding channel 14 is substantially perpendicular to the central axis of the accommodating hole 12 .

[0144] For example, the blocking member 133 may include a blocking rod, one end of which is connected to the locking member 132 , and the other end of which is directed upwards of the locking member 132 along the vertical direction G.

[0145] In the embodiment of the present disclosure, the blocking member 133 is closer to the sliding channel 14 of the mold base 10 than the placement groove 1321 .

[0146] In the embodiment of the present disclosure, by providing a blocking member 133, when the driving member 131 drives the locking member 132 to move to push the hind toe of the chicken claw to disengage the chicken claw from the mold base 10, the blocking member 133 can push the chicken claw to move, making it easier for the chicken claw to follow the movement of the locking member 132, thereby more conveniently disengaging the chicken claw from the mold base 10. At the same time, to prevent the blocking member 133 from abutting against the mold base 10 and affecting the movement of the locking member 132 toward the inside of the mold base 10, a sliding channel 14 is provided in the mold base 10. The blocking member 133 can enter the accommodating hole 12 from the side surface 102 of the accommodating hole 12, and then enter the sliding channel 14 from the accommodating hole 12. When the driving member 131 drives the locking member 132 to move, the blocking member 133 slides along the sliding channel 14, avoiding affecting the movement of the locking member 132.

[0147] In an embodiment of the present disclosure, when toe clipping is not performed, the blocking member 133 is located outside the mold base 10 so that the toes of the chicken claw can contact the blocking member 133. For example, the position of the blocking member 133 on the locking member 132 can be set as needed, so that when the chicken claw is placed on the mold base 10, the blocking member 133 is located between two adjacent front toes of the chicken claw. This allows the chicken claw to be placed on the locking member 132 and the rear toes of the chicken claw to be placed in the placement groove 1321. At the same time, the adjacent two front toes of the three front toes of the chicken claw are connected, and the blocking member 133 can push the connection of the chicken claw, thereby more conveniently separating the chicken claw from the mold base 10.

[0148] According to some embodiments of the present disclosure, the detector is located within the barrier 133 .

[0149] In an embodiment of the present disclosure, when the chicken claw is placed on the locking member 132, the blocking member 133 is located between two adjacent front toes of the three front toes of the chicken claw. At this time, the staff gives the chicken claw a push, which can make the connection of the chicken claw give the blocking member 133 a push, so that the detector located in the blocking member 133 feels the force, and controls the movement of the locking member 132 through the driving member 131, so that the chicken claw is fixed on the mold base 10.

[0150] In some embodiments of the present disclosure, the locking mechanism 130 further includes a limiting member 134 , one end of which is connected to the free end of the blocking member 133 , and the other end of the limiting member 134 faces the placement slot 1321 .

[0151] Exemplarily, the extending direction of the limiting member 134 intersects with the extending direction of the blocking member 133 .

[0152] Exemplarily, the limiting member 134 may include a limiting rod, one end of which is connected to the blocking member 133 , and the other end of the limiting member 134 is a free end.

[0153] In the embodiment of the present disclosure, when the toe clipping is completed and the locking member 132 moves outward, the limiting member 134 will also apply downward pressure to the chicken claw, so that the chicken claw can enter the storage device located below, which is more convenient.

[0154] Exemplarily, the extending direction of the limiting rod is perpendicular to the extending direction of the blocking rod.

[0155] 15 to 17 , the locking mechanism 130 further includes a shielding member 135 , which can be used to shield and protect the locking member 132 . For example, shielding members 135 can be provided on both sides of the locking mechanism 130 .

[0156] In some embodiments of the present disclosure, FIG18 shows a structural diagram of a locking mechanism in a toe clipping device according to another exemplary embodiment of the present disclosure. FIG19 shows a front view of a locking mechanism in a toe clipping device according to another exemplary embodiment of the present disclosure. FIG20 shows a structural diagram of a toe clipping device according to another exemplary embodiment of the present disclosure. Referring to FIG18 to FIG20, the locking mechanism 130 includes a driving member 131 and a locking member 132. The placement slot 1321 and the blocking member 133 on the locking member 132 can be driven to move by a driving member 131, making the structure of the locking mechanism 130 simpler.

[0157] Referring to Figures 15 and 16, in other embodiments of the present disclosure, the locking mechanism 130 includes a connecting member 136 and a blocking member 133 connected to the connecting member 136, the blocking member 133 is located on the side of the placement slot 1321 close to the accommodating hole 12, the driving member 131 is connected to the connecting member 136, and the driving member 131 is configured to drive the connecting member 136 to move so that the blocking member 133 can be located in the sliding channel 14 and slide along the sliding channel 14.

[0159] During the locking process, the driver 131 drives the locking member 132 to move, pressing against the hind toe of the chicken claw, thereby securing the hind toe of the chicken claw in the receiving hole 12. Simultaneously, the chicken claw pushes the connecting member 136 to move, causing the limiting member 134 connected to the connecting member 136 to slide along the sliding channel 14, thereby preventing the movement of the chicken claw from being affected. After the toe clipping is completed, the driver 131 drives the connecting member 136 to move, causing the limiting member 134 on the connecting member 136 to push the chicken claw away from the side 102 of the mold base 10. Simultaneously, the chicken claw pushes the locking member 132 to move, thereby preventing the movement of the chicken claw from being affected.

[0160] In the embodiment of the present disclosure, the locking member 132 and the limiting member 134 are provided separately, so that the locking member 132 and the limiting member 134 can be driven separately without affecting each other, which is more convenient.

[0161] In some embodiments of the present disclosure, the accommodating groove 112 includes three sub-accommodating grooves 1121 corresponding one-to-one to the three front toes, and the other end of the sliding channel 14 is located between any two adjacent sub-accommodating grooves 1121.

[0162] In the embodiment of the present disclosure, the other end of the sliding channel 14 is arranged between any two adjacent sub-accommodating grooves 1121 without changing the shape of the mold base 10 .

[0163] In some embodiments of the present disclosure, a positioning mechanism can be used to fix the chicken feet in the receiving groove 112 of the mold base 10.

[0164] The toe clipping device may further include a positioning mechanism and a toe clipping mechanism. The description of the positioning mechanism and the toe clipping mechanism can be found in the above description of the positioning mechanism and the toe clipping mechanism in the toe clipping machine, which will not be repeated here.

[0165] Another aspect of the present disclosure provides a toe clipping method using the toe clipping device in the above embodiment.

[0166] FIG21 shows a flow chart of a toe clipping method according to an exemplary embodiment of the present disclosure. Referring to FIG21 , the method includes:

[0167] Step S201: placing the claw portion to be trimmed onto the working surface of the die base of the toe trimming machine.

[0168] Step S202: controlling the positioning mechanism to fix the claw portion to be sheared at a preset position on the working surface.

[0169] Step S203: controlling the toe clipper of the toe clipping mechanism to move toward the nail of the claw to be clipped fixed at a preset position, and controlling the detection device of the toe clipping mechanism to detect the contact state between the toe clipper and the claw to be clipped.

[0170] Step S204: Based on the result of the detection device detecting the contact state between the toe clipper and the toe portion to be clipped, the toe clipper is controlled to clip the toe portion to be clipped.

[0171] According to some embodiments of the present disclosure, the positioning mechanism includes a toe positioning assembly, the toe positioning assembly including a plurality of pressure plates arranged side by side, wherein the positioning mechanism is controlled to fix the claw portion to be sheared at a preset position on the work surface, and the method includes:

[0172] The plurality of pressing pieces are controlled to apply pressure to the toes of the claw portion to be sheared so as to fix and flatten the toes, and the claw portion to be sheared is fixed at a preset position on the working surface.

[0173] According to some embodiments of the present disclosure, a toe positioning assembly includes a support member, a plurality of pressing plates having through holes, the support member passing through the through holes of the plurality of pressing plates, the plurality of pressing plates being provided on the support member, and controlling the plurality of pressing plates to apply pressure to the toes of the claw portion to be trimmed to fix and flatten the toes, so that the claw portion to be trimmed is fixed to a preset position on the work surface, including:

[0174] The control support moves toward the working surface of the mold base to drive the multiple pressing plates to move, so that the multiple pressing plates exert pressure on the toes of the claw part to be sheared under the action of their own gravity to fix and flatten the toes, so that the claw part to be sheared is fixed at a preset position on the working surface.

[0175] According to some embodiments of the present disclosure, the method further includes:

[0176] In response to the distance between the toe clipping knife and the pressing plate being less than a preset distance value, the support member is controlled to move in a direction away from the working surface of the mold base to drive the pressing plate among the multiple pressing plates whose distance from the toe clipping knife is less than the preset distance value to move, thereby releasing the pressure on the toes to be clipped by the claws.

[0177] According to some embodiments of the present disclosure, step S203 includes:

[0178] The control detection device detects the resistance encountered by the toe clipper during the movement.

[0179] According to some embodiments of the present disclosure, a toe clipping mechanism includes a driving member, a toe clipping knife connected to the driving member, controlling the toe clipping knife of the toe clipping mechanism to move toward a toe nail of a claw portion to be clipped fixed at a preset position, and controlling a detection device to detect the resistance encountered by the toe clipping knife during the movement, including:

[0180] The driving member is controlled to drive the toe clipper to move; and the detection device is controlled to detect at least one of the voltage value, the current value and the pressure value of the driving member to determine the change in resistance encountered by the toe clipper during the movement.

[0181] According to some embodiments of the present disclosure, based on a result of a detection device detecting a contact state between a toe clipper and a toe portion to be clipped, controlling the toe clipper to clip the toe portion to be clipped includes:

[0182] In response to the driving member current value reaching a first preset value during the movement of the toe clipper, the toe clipper is controlled to clip the toes of the claw portion to be clipped.

[0183] According to some embodiments of the present disclosure, the method further includes:

[0184] When the die base is located below the positioning mechanism, controlling the lifting mechanism to drive the die base to move toward the positioning mechanism so that the positioning mechanism can fix the claw portion to be sheared at a preset position on the work surface; and

[0185] After the toe trimming is completed, the lifting mechanism is controlled to drive the mold base to move away from the positioning mechanism.

[0186] According to some embodiments of the present disclosure, the method further includes:

[0187] After the toe trimming is completed, the ejection mechanism is controlled to release the fixed positioning of the claw portion to be trimmed at the preset position.

[0188] According to some embodiments of the present disclosure, in the case where the toe trimming machine includes multiple die sets, the toe trimming method includes:

[0189] Placing the plurality of claws to be sheared onto the working surfaces of the plurality of die bases, respectively, wherein the rear toes of the claws to be sheared are accommodated in the corresponding accommodation holes of the die bases, and the plurality of front toes of the claws to be sheared are accommodated in the corresponding accommodation grooves of the die bases;

[0190] Controlling the driving mechanism to drive the plurality of die holders to move sequentially to positions opposite to the toe-cutting mechanism; and

[0191] For the die holder that moves to a position opposite to the toe trimmer mechanism:

[0192] The positioning mechanism is controlled to fix the claw to be sheared placed on the die base on the working surface of the die base; and the toe shearing mechanism is controlled to shear the claw to be sheared positioned on the working surface of the die base.

[0193] In the example, taking the chicken claws to be trimmed as an example, multiple chicken claws can be manually placed on the working surfaces of multiple mold bases, wherein the hind toes of the chicken claws are accommodated in the accommodating holes that pass through the working surface, and the three front toes of the chicken claws are respectively accommodated in the three accommodating grooves on the working surface.

[0194] Then, the driving mechanism can be controlled to drive the plurality of mold bases to move in sequence to positions relative to the positioning mechanism. For example, a motor drives a reducer, which is then driven by a sprocket to drive the mold bases to move step by step.

[0195] After the chicken claw die base is moved to the shearing station, a lifting cylinder drives the die base to move and position it. Simultaneously, a positioning mechanism is controlled to secure the chicken claw placed on the die base to a preset position on the die base. The structure of the positioning mechanism can be seen in the explanation above. For the left, middle, and right fingers, multiple pressure plates are controlled to apply pressure to the toes of the claw to be sheared by their own weight, thereby securing and flattening the toes. A pressure member applies pressure to the claw surface of the chicken claw, securing the claw to be sheared at a preset position on the work surface. Furthermore, the rear toe is positioned using a rear toe guide plate.

[0196] Next, the toe-cutting mechanism is controlled to trim the chicken paw positioned on the working surface of the die base. The toe-cutting mechanism's three blades, on the left, center, and right, are driven by three separate motors, driven by guide rails and sliders, while the rear toe shears are propelled by a pneumatic lift cylinder. Once the chicken paw is positioned, the blades advance until the nail enters the cutting edge. When this is blocked, the blades become unable to advance, and the four pneumatic shears simultaneously cut. The propulsion force of the left, center, and right blades is fed back by the motor's voltage and current, while the propulsion force of the rear toe is controlled by the lift cylinder's pressure. As the blades advance, the three pressure plates are lifted one by one to clear the cutting space for the blade tips, ensuring that the pressure plates maintain a stable position on the chicken paw's toes.

[0197] After toe clipping is completed, the lifting mechanism is controlled to drive the die base away from the positioning mechanism, and the toe clipping knife, pressure piece, pressing plate, and lifting cylinder are controlled to retract. The sheared chicken feet move to the ejection station, and the ejector rod is controlled to eject the chicken feet.

[0203] In some embodiments of the present disclosure, the lengths of the through holes 2112 on the plurality of pressing plates 211 increase successively in the direction from the nail of the claw to be trimmed to the middle of the claw to be trimmed, and the length direction of the through holes 2112 is parallel to the vertical direction.

[0204] In some embodiments of the present disclosure, the positioning mechanism 20 also includes a claw surface positioning assembly 22, which includes a driving unit 221 and a pressure piece 222.
