Description

Technical Field

[0001] The invention relates to the technical field of clamping plate structures, and in particular to a clamping plate mechanism with a telescopic suction cup. Background Art

[0002] Food safety issues are attracting more and more attention. How to ensure that consumers can eat safe and reliable food has become an urgent problem for many food processing companies. For this reason, many food production companies, especially some large slaughterhouses, often put labels on the feet of their slaughtered chickens, ducks, geese and other poultry products, and print QR codes, barcodes, anti-counterfeiting codes and other information on the labels. Consumers can use this information to determine whether the food is produced by a regular manufacturer and whether it is safe. At the same time, they can track and trace it according to the label information.

[0003] In order to achieve automated production, labeling machines for sticking labels on the feet of poultry are now available on the market, including a label transmission mechanism and a clamping plate mechanism. The clamping plate mechanism includes a driving member connected to the working platform, and two clamping plates are provided at the driving end of the driving member. The clamping plates are penetrated by suction holes, and the suction holes are connected to the vacuum pump through pipes. A space for placing the poultry claws is formed between the two clamping plates. The two clamping plates adsorb the same label transmitted by the label transmission mechanism through the suction action of the suction holes, and the sticky side of the label faces the side away from the clamping plate, and then is flipped in the right direction under the driving action of the driving member. When the two clamping plates are flipped until they are in contact with each other, the same label on the two clamping plates can be attached and bonded to each other, and the unbonded part of the label forms a ring sleeve on the ankle of the poultry claw.

[0004] Although this method can stick the label on the poultry claw to a certain extent, the spacing between the two clamps is fixed, so the size of the ring formed by the unbonded part of the label after sticking is also fixed. Therefore, when the poultry claw is small, and the size of the ring formed by the unbonded label is much larger than the outer size of the poultry claw, the ring formed by the attached label can easily pass through the claw of the poultry claw and separate from it, so that the label will not be firmly attached to the poultry claw. That is, the clamping mechanism of the existing labeling machine can only realize the label bonding function, but is not suitable for poultry claws of different sizes, and there is still a defect that needs to be improved. Summary of the invention

[0014] The present invention has the following beneficial effects:

When the U-shaped plate slides downward, the transmission rod pulls the clamping arm to flip downward around the hinge point between it and the mounting plate, so that the two clamping arms are unfolded until the end surface of the clamping arm close to the air suction hole is in a horizontal state. When the label transmission device transmits the label to the air suction hole of the clamping arm, the air is sucked by the vacuum pump. Since the extension rod and the straight groove are sealed and plugged, and the label and the several air suction holes of the clamping arm are in contact with each other, the inner cavity of the clamping arm is in a negative pressure state. According to the principle of atmospheric pressure balance, the inner cavity in the clamping arm at a low pressure can absorb the label and attract the extension rod to move inward, thereby realizing the function of absorbing the label.

[0016] Furthermore, when a rod-shaped object such as a bird claw is placed between the two clamp arms, and the sliding drive member drives the U-shaped plate to move upward, the transmission rod will push the clamp arms to move upward, thereby realizing the function of the two clamp arms folding to a fitted state, and at the same time driving the same label sucked by the two clamp arms to fit and adhere to each other. In order to separate the fitted label from the clamp arm, the vacuum pump will stop the operation of pumping air from the suction hole, so that the inner cavity of the clamp arm is connected to the outside world through the pipeline and the vacuum pump, and the external gas will be replenished to the inner cavity of the clamp arm in a negative pressure state through the pipeline. At this time, since the two clamp arms are still in a fitted state, according to the principle of atmospheric pressure balance, the negative pressure inside the clamp arm will push the extension rod to move outside the straight groove when there is gas supply. The extending rod is located near the hinge point between the clamp arm and the mounting plate. Therefore, when the extending rod moves out of the straight groove, it will abut against the annular outer peripheral surface formed by the unbonded part of the label until the extending rod and the poultry claw abut against each other, so that most of the labels are bonded together. Therefore, it can be adapted to bonding labels to poultry claws of different sizes, thereby achieving the beneficial effect of improving the bonding firmness. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" cited in this specification are only for the convenience of description, and are not used to limit the scope of the present invention. The change or adjustment of their relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0027] Reference Figures 1 to 8 As shown, a labeling machine for attaching labels to poultry claws comprises a working platform a with a housing b installed thereon, a label transmission device e and a clamping plate mechanism c are arranged on the working platform a, and the label transmission device e and the clamping plate mechanism c are both located in the housing b.

[0028] The label transmission device e moves the label toward the clamping mechanism c. A control panel d is installed on the housing b to control the label transmission device e and the clamping mechanism c and record the information on the label.

[0029] The following is a detailed introduction to the specific structure of the clamping mechanism c of the labeling machine:

[0030] Reference Figures 1 to 8As shown, a clamping mechanism c with a telescopic suction cup includes a base 1 provided with a mounting plate 2, the base 1 is fixed to the top surface of the working platform a by screws, the mounting plate 2 is slidably connected to a U-shaped plate 3 with a U-shaped notch facing upward, the plane of the U-shaped plate 3 and the plane of the mounting plate 2 are arranged parallel to each other, the mounting plate 2 is provided with a sliding drive member for controlling the sliding of the U-shaped plate 3, both ends of the U-shaped plate 3 are hinged with a transmission rod 31, the end of the transmission rod 31 away from the U-shaped plate 3 is hinged with a clamping arm 32, and the end of the clamping arm 32 close to the other clamping arm 32 is hinged to the mounting plate 2. Therefore, the hinge point between the clamp arm 32 and the transmission rod 31 is set at the side of the clamp arm 32 away from the other clamp arm 32. When the sliding drive member drives the U-shaped plate 3 to slide upward, since the hinge point between the clamp arm 32 and the mounting plate 2 is relatively fixed, in the process of the distance between the clamp arm 32 and the U-shaped plate 3 gradually decreasing, the transmission rod 31 drives the clamp arm 32 to flip upward around the hinge point between the clamp arm 32 and the mounting plate 2, thereby realizing the function of flipping and fitting the two clamp arms 32 in opposite directions.

[0031] The clamp arm 32 is hollow, and a straight groove 325 is provided on the side of the clamp arm 32 near the hinge point of the mounting plate 2. The cross section of the straight groove 325 is circular, and the straight groove 325 is connected to the inner cavity of the clamp arm 32. The straight groove 325 is sealed and plugged with a protruding rod 33. The end surface of the clamp arm 32 facing the other clamp arm 32 along the flipping direction is provided with a plurality of suction holes 341 connected to the inner cavity of the clamp arm 32. The suction holes 341 are connected to the existing vacuum pump through a pipeline, thereby realizing the function of vacuuming or decompression. In this embodiment, the structure of the clamp arm 32 and the suction hole 341 is the structure of the suction cup in the main body name.

[0032] Specifically, under the driving action of the sliding drive member, the U-shaped plate 3 is driven to slide and the transmission rod 31 is driven to push or pull the two clamping arms 32 to fold or unfold. When the U-shaped plate 3 slides downward, the transmission rod 31 pulls the clamping arms 32 to flip downward around the hinge point between the mounting plate 2, so that the two clamping arms 32 are unfolded until the end surface of the clamping arms 32 close to the air suction hole 341 is in a horizontal state. When the label transmission device e transmits the label to the air suction hole 341 of the clamping arm 32, the vacuum pump is used to evacuate the label. Since the extension rod 33 and the straight groove 325 are sealed and plugged, and the label and the several air suction holes 341 of the clamping arm 32 are in contact with each other, the inner cavity of the clamping arm 32 is in a negative pressure state. According to the principle of atmospheric pressure balance, the inner cavity of the clamping arm 32 at low pressure can absorb the label and attract the extension rod 33 to move inward, thereby realizing the function of absorbing the label.

[0033] Reference Figures 1 to 8As shown, further, when a rod-shaped object such as a bird claw is placed between the two clamp arms 32, and then in the process of the sliding drive member driving the U-shaped plate 3 to move upward, the transmission rod 31 will push the clamp arms 32 to move upward, thereby realizing the function of the two clamp arms 32 folding to each other to a fitted state, and at the same time driving the same label sucked by the two clamp arms 32 to fit and adhere to each other. In order to separate the fitted label from the clamp arms 32, the vacuum pump will stop the operation of pumping air from the suction hole 341, so that the inner cavity of the clamp arms 32 is connected to the outside through the pipeline and the vacuum pump, and the external gas will be replenished to the inner cavity of the clamp arms 32 in a negative pressure state through the pipeline. At this time, since the two clamp arms 32 are still in a fitted state, according to the principle of atmospheric pressure balance, the negative pressure inside the clamp arms 32 will push the extension rod 33 to move out of the straight groove 325 when there is gas supply. The extending rod 33 is located near the hinge point between the clamp arm 32 and the mounting plate 2. Therefore, when the extending rod 33 moves out of the straight groove 325, it will abut against the annular outer peripheral surface formed by the unbonded portion of the label until the extending rod 33 abuts against the poultry claw, so that most of the labels are bonded together. Therefore, it is possible to adapt to bonding the labels to poultry claws of different sizes, thereby achieving the beneficial effect of improving the bonding firmness.

[0034] In order to make the extension rod 33 more effectively abut against the outer peripheral surface of the annular part of the label. The side of the clamp arm 32 facing the hinge point between the clamp arm 32 and the mounting plate 2 is integrally connected with a hinge block 324, the clamp arm 32 is hinged to the mounting plate 2 through the hinge block 324, the straight groove 325 of the clamp arm 32 is directly opposite to the hinge point between the clamp arm 32 and the mounting plate 2, the end of the extension rod 33 protruding outside the clamp arm 32 is fixedly connected to a limit block 333, the limit block 333 is coplanar with the end face of the clamp arm 32 close to the air suction hole 341, the limit block 333 is fixedly connected to the side of the clamp arm 32 with a plug-in block 334, and the side of the clamp arm 32 facing the limit block 333 is provided with a slot 322 for the plug-in block 334 to be plugged in. The end face of the clamp arm 32 away from the air suction hole 341 is integrally connected with an extension block 323, and the clamp arm 32 is hinged to the transmission rod 31 through the extension block 323.

[0035] Specifically, the straight groove 325 of the clamp arm 32 is directly opposite to the hinge point between the clamp arm 32 and the mounting plate 2, so that when the extension rod 33 moves out of the straight groove 325, the limiting effect of the hinge point between the extension rod 33, the hinge block 324 and the mounting plate 2 can be utilized, thereby reducing the situation where the extension rod 33 is completely separated from the straight groove 325, and forming a starting limiting effect on the movement of the extension rod 33. In addition, since the limiting block 333 is coplanar with the end surface of the clamp arm 32 close to the air suction hole 341, when the two clamp arms 32 are flipped and attached in opposite directions, the two limiting blocks 333 can also be attached to each other and abut against the label. When the vacuum pump is in a depressurized state, the two limiting blocks 333 are simultaneously extended out of the clamp arm 32 due to the air pressure, which can achieve a more effective tightening and shrinking of the ring-shaped attachment of the middle part of the label, thereby achieving the function of improving the label firmly attached to the poultry claw.

[0036] Reference Figures 1 to 8 As shown, in the actual production process, the interior of the clamp arm 32 is set to a hollow structure, which is difficult to process. In order to effectively reduce the processing difficulty and achieve effective processing. The end surface of the clamp arm 32 near the air intake hole 341 is provided with an opening 321, and the opening 321 is connected to the inner cavity of the clamp arm 32. The opening 321 of the clamp arm 32 is covered and plugged with a cover plate 34, and the cover plate 34 is locked and connected to the edge of the opening 321 of the clamp arm 32 by screws, and a number of air intake holes 341 are opened on the cover plate 34. Specifically, the clamp arm 32 is divided into two parts: the clamp arm 32 body and the cover plate 34. During processing, the inner cavity facing the clamp arm 32 can be cut in and out at the opening 321 of the clamp arm 32 by numerical control technology, so as to form the inner cavity of the clamp arm 32, and then the cover plate 34 is installed to the opening 321 of the clamp arm 32, so that the cover plate 34 and the inner wall of the clamp arm 32 form the inner cavity of the integral clamp arm 32, which has the effect of simple processing operation and easy realization.

[0037] In order to realize the function of sealing and plugging the extension rod 33 with the straight groove 325, the outer circumferential surface of the extension rod 33 is provided with a plurality of annular grooves 331 along the length direction thereof, and a sealing ring 332 is fixedly connected in the annular groove 331, and the extension rod 33 abuts against the inner wall of the straight groove 325 through the sealing ring 332. Specifically, by providing a plurality of annular grooves 331 along the length direction of the extension rod 33, it is convenient to install a plurality of sealing rings 332, and the extension rod 33 is provided with a plurality of sealing rings 332 to abut against the inner wall of the straight groove 325, on the one hand, in order to utilize the effective sealing characteristics of the sealing ring 332, and on the other hand, because the extension rod 33 will frequently extend or insert in the straight groove 325, and the sealing ring 332 abuts against the inner wall of the straight groove 325, and there is relative friction, when the movement times are large or the movement stroke is large, the surface of part of the sealing ring 332 will be worn, thereby increasing the gap between the sealing ring 332 and the inner wall of the straight groove 325, and reducing the sealing performance inside the clamp arm 32.

[0038] Reference Figures 1 to 8 As shown, by setting up multiple sealing rings 332, it is more difficult for the gas to be discharged from the gaps between the multiple sealing rings 332 and the inner wall of the straight groove 325. Therefore, setting up multiple sealing rings 332 can effectively solve the problem of wear on the surface of the sealing ring 332 and at the same time increase the service life.

[0039] The side of the mounting plate 2 away from the base 1 is connected to the connecting plate 23 by screw locking. The connecting plate 23 is located between the two clamping arms 32 and is directly opposite to the U-shaped notch of the U-shaped plate 3. The hinge point between the clamping arm 32 and the mounting plate 2 is located on the connecting plate 23, that is, the clamping arm 32 is hinged to the connecting plate 23 through the hinge block 324. The end surface of the connecting plate 23 away from the base 1 is provided with a placement groove 231, which is connected to the front and rear sides of the base 1. The placement groove 231 is arranged in a U-shaped manner, and the hinge points between the connecting plate 23 and the two clamping arms 32 are arranged on both sides of the placement groove 231. Specifically, by arranging the connecting plate 23 on the mounting plate 2, the function of locating the ankle of the poultry claw can be realized. When it is necessary to label the poultry claw, the ankle of the poultry claw can be placed in the placement groove 231 of the connecting block 22 in advance, and then the next step of labeling operation is carried out through the driving action of the sliding drive member.

[0040] Reference Figures 1 to 8 As shown, in order to realize the function that the several air suction holes 341 of the clamp arm 32 are connected to the air pump through pipelines. The end face of the clamp arm 32 away from the air suction hole 341 is provided with an air connection head 361, and the air connection head 361 is connected to the inner cavity of the clamp arm 32. The end face of the U-shaped plate 3 away from its U-shaped notch is fixedly connected with a protrusion 35, and the protrusion 35 is fixedly connected with two mounting columns 351. A tee head 36 is inserted between the two mounting columns 351. The end of the mounting column 351 away from the protrusion 35 is threadedly connected with a limit screw, and the tee head 36 abuts against the limit screw. The tee head 36 is respectively connected to the air connection head 361 and the air pump through pipelines. Specifically, by providing two mounting columns 351 on the protrusion 35, one end of the tee head 36 is inserted into the position between the two mounting columns 351, and the other two ends of the tee head 36 are located above and abut against the mounting columns 351. In addition, by threading a limit screw on the mounting column 351, the nut of the limit screw abuts against the corner of the tee head 36, thereby achieving the effect of installing and fixing the tee head 36, facilitating external installation operations, and having the effect of simple installation operations.

[0041] In order to realize the function of the sliding driving member driving the U-shaped plate 3 to slide. The sliding drive member includes a first motor 21 that is locked and connected to the side of the mounting plate 2 away from the U-shaped plate 3 by screws, the rotating shaft of the first motor 21 passes through the mounting plate 2, and the driving end of the first motor 21 is coaxially rotated with a first synchronous wheel 211, and the mounting plate 2 is connected to the side of the U-shaped plate 3 by a second synchronous wheel 212, and the second synchronous wheel 212 and the first synchronous wheel 211 are meshed and transmitted with the same synchronous belt 213, and the length direction of the synchronous belt 213 is consistent with the sliding direction of the U-shaped plate 3, and the end surface of the U-shaped plate 3 facing the mounting plate 2 is fixedly connected with a slider, and the slider is fixedly connected to the synchronous belt 213; the mounting plate 2 is connected to the side of the U-shaped plate 3 by screws, and two first slide rails 24 with the same length direction as the length direction of the synchronous belt 213 are connected, and the two first slide rails 24 are arranged on both sides of the connecting block 2, and the U-shaped plate 3 is provided with two moving blocks corresponding to the two first slide rails 24 on the side of the mounting plate 2, respectively, and the moving blocks are slidably connected to the slide rails, thereby improving the sliding guiding effect.

[0042] Reference Figures 1 to 8 As shown, since the two clamping arms 32 need to absorb the labels on the label transmission device e before folding and pasting, in order to reduce the situation where the clamping arms 32 absorb too many labels due to long-term contact between the clamping arms 32 and the transmission end of the labeling transmission device. The top surface of the base 1 is connected to the second motor 45 by screw locking, and the driving end of the second motor 45 is coaxially rotated with the first eccentric wheel 44. The top surface of the base 1 is connected to two mounting seats 4 by screw locking, and the two mounting seats 4 are distributed on both sides of the mounting plate 2. The two mounting seats 4 are rotatably connected to the same rotating rod 41, and the axial direction of the rotating rod 41 is consistent with the axial direction of the rotating shaft of the second motor 45. The mounting plate 2 rotates coaxially with the rotating rod 41, and one end of the rotating rod 41 is coaxially rotated with the second eccentric wheel 42. The eccentric end of the first eccentric wheel 44 is rotatably hinged with a synchronous rod 43, and the end of the synchronous rod 43 away from the first eccentric wheel 44 is hinged with the eccentric end of the second eccentric wheel 42.

[0043] Specifically, a second motor 45 is arranged on the base 1 to drive the first eccentric wheel 44 and the second eccentric wheel 42 to realize synchronous swinging movement through the synchronization rod 43. Since the mounting plate 2 and the rotating rod 41 are coaxially rotated, the second motor 45 drives the clamping mechanism c as a whole to rotate around the axis of the rotating rod 41 to perform a flipping movement inside or outside the labeling machine. When flipping inward, the clamping arm 32 of the clamping mechanism c can be made close to the label output end of the label transmission device e in the labeling machine, so that the suction hole 341 on the clamping arm 32 can absorb the label; in addition, when flipping outward, on the one hand, the clamping arm 32 of the clamping mechanism c can be moved away from the label transmission device e, and at the same time, the clamping arm 32 of the clamping mechanism c can be extended out of the shell b of the labeling machine, so that the poultry claw can be placed on the placement groove 231 of the connecting plate 23 outside the labeling machine, thereby shortening the operating distance and achieving the beneficial effect of facilitating operation.

[0044] In order to make the clamping arm 32 of the clamping mechanism c close to the transmission end of the label transmission device e under the linkage effect of the first eccentric wheel 44, the second eccentric wheel 42 connected by the synchronization rod 43, and in order to effectively make the suction holes 341 of the two unfolded clamping arms 32 abut against the label. The rotating rod 41 has two connecting seats 5 that rotate coaxially. The connecting seat 5 is in the shape of a long strip. One end of the connecting seat 5 rotates coaxially with the rotating rod 41. The two connecting seats 5 are arranged on both sides of the mounting plate 2 along the axis direction of the rotating rod 41. The mounting plate 2 is slidably connected to the connecting seat 5. The side of the mounting plate 2 facing the connecting seat 5 is connected to the second slide rail 25 by screw locking. The length direction of the second slide rail 25 is consistent with the length direction of the connecting seat 5. The connecting seat 5 is connected to the side of the mounting plate 2 by screw locking. The sliding block 54 is slidably connected to the second slide rail 25. The two connection seats 5 are fixedly connected with the same fixing bar 51, and the fixing bar 51 is connected with the third motor 52 by screw locking. The driving end of the third motor 52 is coaxially rotated with a lead screw 53, and the length direction of the lead screw 53 is consistent with the sliding direction of the mounting plate 2. The mounting block is fixedly connected with the connecting block 22, and the lead screw 53 is threaded through the connecting block 22. Therefore, under the sliding limit action of the second slide rail 25 and the sliding block 54, the driving action of the third motor 52 can realize the function of moving the clamping mechanism c as a whole in the direction away from or close to the rotating rod 41. Specifically, when the clamping arm 32 of the clamping mechanism c is flipped to face the label at the end of the label transmission device e, the driving action of the third motor 52 drives the clamping arm 32 of the clamping mechanism c and the label at the end of the label transmission device e to press against each other, so as to achieve the function of absorbing the label on the clamping arm 32.

[0045] Since the clamp mechanism c is mainly used in slaughterhouses or processing plants for slaughtering poultry products such as chickens, ducks, geese, etc., due to the working environment, there are often splashing liquids or poultry feathers in the on-site environment, and the internal working process of the clamp mechanism c involves mechanical transmission movements such as the pulley mechanism transmission movement, the screw 53 mechanism transmission movement, and the eccentric wheel linkage transmission mechanism movement. In order to reduce the impurities such as feathers or liquids in the external environment from entering the labeling machine and causing the mechanical movement to get stuck, the connecting seat 5 is provided with a baffle 39, which is located on the side of the U-shaped plate 3 away from the mounting plate 2, and the baffle 39 covers the U-shaped plate 3 and the mounting plate 2.

[0046] When the splint mechanism c is working:

[0047] Step 1: When the two clamping arms 32 are in a fully extended state, the first eccentric wheel 44 is driven to rotate by the second motor 45, so that the second eccentric wheel 42 is pulled to move by the synchronization rod 43, so that the mounting plate 2 and the clamping arms 32 are turned toward the inside of the labeling machine as a whole, and the turning movement is stopped when the air suction hole 341 of the clamping arm 32 is directly opposite to the bottom of the label at the end of the label transmission device e;

[0048] Step 2: Use the camera on the fixed bar 51 to shoot the information facing the label, and verify and record the information on the label through the existing information verification technology. When the verification is correct and the record is saved and stored in the system storage end, proceed to the next step;

[0049] Step 3: Under the driving action of the third motor 52, the driving screw 53 rotates continuously. Since the mounting plate 2 is slidably connected to the connecting seat 5 through the slide rail, the mounting plate 2 and the clamping arm 32 are driven to move toward the label at the end of the label transmission device e as a whole, so that the suction hole 341 on the clamping arm 32 abuts against the label, and then the suction effect of the vacuum pump is used to simultaneously evacuate the suction holes 341 of the two clamping arms 32 through the three-way pipe, so as to absorb the same label; then the third motor 52 and the second motor 45 are driven backward successively, so that the clamping arm 32 is away from the label transmission device e and the mounting plate 2 and the clamping arm 32 are driven to move toward the outside of the labeling machine as a whole, so as to facilitate the labeling operation outside the labeling machine;

[0050] Step 4: Also under the driving action of the third motor 52, the driving screw 53 is continuously rotated, thereby driving the entire structure of the mounting plate 2 and the clamping arm 32 to move in a direction away from the rotating rod 41, so that the placement groove 231 of the connecting plate 23 and the ankle of the poultry claw are mutually abutted and positioned, so that the poultry claw is located in the placement groove 231, thereby achieving the effect of improving the effectiveness of labeling;

[0051] Step 5: Under the driving action of the first motor 21, the first synchronous wheel 211 is driven to rotate continuously. Since the synchronous belt 213 is meshed with the first synchronous wheel 211 and the second synchronous wheel 212 for transmission, the U-shaped plate 3 is driven to move toward the direction close to the connecting plate 23. Since the hinge point between the clamp arm 32 and the connecting plate 23 is relatively fixed to the mounting plate 2, and the hinge point between the transmission rod 31 and the clamp arm 32 is located on the side of the hinge point between the clamp arm 32 and the connecting plate 23 away from the placement groove 231, in the process of the distance between the connecting plate 23 and the U-shaped plate 3 gradually decreasing, the transmission rod 31 will push the clamp arm 32 to flip, so that the clamp arm 32 flips around the hinge point between the clamp arm 32 and the connecting plate 23 toward the other clamp arm 32, so that the two clamp arms 32 abut against each other and fit together, and at the same time, the label is fitted around the poultry claw, and the unfitted part forms a ring sleeve on the ankle of the poultry claw;

[0052] Step 6: After the label is attached, the vacuum pump releases the pressure, and the suction hole 341 of the contact clamp arm 32 absorbs the label. At the same time, according to the principle of atmospheric pressure balance, the extension rod 33 will also drive the extension rod 33 to move in the direction of extending out of the straight groove 325. At this time, since the two clamp arms 32 are still in a state of mutual attachment, and the two limit blocks 333 are also in a state of mutual attachment, the two limit blocks 333 will further attach the unattached label in the pressure relief state until the limit blocks 333 abut against the poultry claws, thereby achieving the function of firmly attaching the label to the poultry claws. At the same time, it can be suitable for poultry claws of different sizes and has a universal effect of use.

[0053] Step 7: The first motor 21, the second motor 45, and the third motor 52 are driven in reverse, so that the clamping mechanism c is reset to the initial state, thereby completing the operation.
