Technical Field
[0001] The utility model relates to the technical field of livestock breeding equipment, in particular to a high-speed self-resetting electric ear tag pliers. Background Art
[0002] An ear tag pliers is a commonly used tool in the breeding production process, used to attach ear tags or two-dimensional codes to the ears of animals such as pigs, cattle, and sheep for subsequent management and epidemic prevention work in the breeding process. During the process of using a traditional ear tag pliers to tag animals, the operator needs to manually press the two handles of the ear tag pliers to make the lower ear tag pass through the animal's ear and embed it into the upper ear tag, and then release the handles and manually remove the front end of the ear tag pliers from the animal's ear. Since the above actions are all manually completed by the operator, during the tagging process, the animal will retreat and struggle due to pain. If the pressing action of the handle is slow or the withdrawal action of the ear tag pliers is not timely, it will cause a gap in the animal's ear and the tagging operation will fail. At the same time, the manual tagging efficiency of the operator is relatively low. Therefore, the traditional ear tag pliers still have certain limitations.
[0003] Therefore, a high-speed self-resetting electric ear tag pliers that solves the above problems is needed. Summary of the Utility Model
[0004] The utility model provides a high-speed self-resetting electric ear tag pliers, which realizes automatic tagging and rapid retraction of two pliers arms, improves the tagging efficiency, and effectively avoids the occurrence of a gap in the animal's ear and the failure of the tagging operation caused by the struggle of the animal.
[0005] The technical solution of the utility model is realized as follows:
[0006] The high-speed self-resetting electric ear tag pliers includes a housing, a mounting plate is slidably installed horizontally in the housing, a first pliers arm and a second pliers arm are hinged on the mounting plate, a reset element is arranged between the first pliers arm and the second pliers arm, and a driving component is further included for driving the opening and closing of the first pliers arm and the second pliers arm and driving the mounting plate to move horizontally.
[0007] The driving assembly includes a rotating shaft rotatably installed in the housing. The rotating shaft is drivingly connected to a driving motor. A guiding groove cam is fixedly installed on the rotating shaft. The guiding groove cam is provided with a semi-circular continuous groove formed by a first arc-shaped groove and a linear groove. A second arc-shaped groove is provided on the linear groove. The semi-circular continuous groove and the second arc-shaped groove form a continuous guiding groove. It further includes a guiding plate disposed between the first clamping arm and the guiding groove cam. The guiding plate is hinged to the mounting plate. A guiding wheel is hinged to the guiding plate. The guiding wheel is constrained and installed in the guiding groove. A long oblong hole is horizontally provided on the guiding plate. The rotating shaft passes through the long oblong hole. A first cam and a second cam are fixedly installed on the rotating shaft. The first cam abuts against the inner wall at the rear end of the first clamping arm. The second cam abuts against the inner wall at the rear end of the second clamping arm.
[0008] As a preferred technical solution, the front end of the first clamping arm extends out of the housing and is provided with a positioning groove for positioning the upper ear tag. An elastic clamping piece for clamping the upper ear tag is fixedly installed at the positioning groove. The front end of the second clamping arm extends out of the housing and is fixedly installed with an ear tag needle for placing the lower ear tag. The ear tag needle is adapted to the positioning groove.
[0009] As a preferred technical solution, a sliding groove is fixedly installed on the housing. A trapezoidal slider is provided at the bottom of the mounting plate. The trapezoidal slider is slidably installed in the sliding groove.
[0010] As a preferred technical solution, it further includes a controller. A handle and a button are provided on the housing. A pair of adapted inductive switches are respectively provided on the housing and the guiding groove cam. The driving motor, the button and the two inductive switches are all electrically connected to the controller.
[0011] Adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0012] Since the high-speed self-resetting electric ear tag pliers include a driving component, during the use of the ear tag pliers, by rotating the driving component, the rotating shaft rotates, and the guide wheel moves from the second arc-shaped groove to the first arc-shaped groove, increasing the distance between the guide wheel and the rotating shaft, and the mounting plate moves away from the rotating shaft, thereby realizing the action of the first pliers arm and the second pliers arm extending out of the housing. At the same time, the distal end of the first cam abuts against the first pliers arm, and the distal end of the second cam abuts against the second pliers arm, thereby realizing the front ends of the first pliers arm and the second pliers arm approaching each other. During the process of the front ends of the first pliers arm and the second pliers arm approaching, the lower ear tag passes through the animal's ear and is embedded in the upper ear tag. After the marking is completed, with the rotation of the rotating shaft, the proximal end of the first cam abuts against the first pliers arm, and the proximal end of the second cam abuts against the second pliers arm. Under the action of the reset component, the front ends of the first pliers arm and the second pliers arm move away from each other. At the same time, the guide wheel moves from the first arc-shaped groove to the second arc-shaped groove, and the mounting plate moves towards the rotating shaft, thereby realizing the rapid retraction of the first pliers arm and the second pliers arm into the housing, completing one ear tag installation action.
[0013] In the present utility model, since the present utility model adopts cam drive, the cam can obtain a relatively high rotation speed under the drive of the motor, so that the marking action and the retraction action of the ear tag pliers can be completed quickly, improving the marking efficiency, and effectively avoiding the occurrence of situations such as the animal's ear having a notch and the marking operation failing due to the animal struggling.

[0025] As Figure 1 And Figure 6As shown together, the driving assembly includes a rotating shaft 5 rotatably installed in the housing 1. The rotating shaft 5 is drivingly connected to a driving motor 6. A guiding groove cam 7 is fixedly installed on the rotating shaft 5. The guiding groove cam 7 is provided with a semi-circular continuous groove 10 formed by a first arc groove 8 and a straight groove 9. A second arc groove 11 is provided on the straight groove 9. The semi-circular continuous groove 10 and the second arc groove 11 form a continuous guiding groove 12. It further includes a guiding plate 13 arranged between the first clamping arm 3 and the guiding groove cam 7. The guiding plate 13 is hinged to the mounting plate 2. A guiding wheel 14 is hinged on the guiding plate 13. The guiding wheel 14 is constrained and installed in the guiding groove 12. A long slotted hole 15 is horizontally arranged on the guiding plate 13. The rotating shaft 5 passes through the long slotted hole 15. A first cam 16 and a second cam 17 are fixedly installed on the rotating shaft 5. The first cam 16 abuts against the inner wall at the rear end of the first clamping arm 3, and the second cam 17 abuts against the inner wall at the rear end of the second clamping arm 4.
[0026] As Figure 2 shown, the front end of the first clamping arm 3 extends out of the housing 1 and is provided with a positioning groove 19 for positioning the upper ear tag 18. An elastic clamping piece 20 for clamping the upper ear tag 18 is fixedly installed at the positioning groove 19. The front end of the second clamping arm 4 extends out of the housing 1 and is fixedly installed with an ear tag needle 22 for placing the lower ear tag 21. The ear tag needle 22 is adapted to the positioning groove 19.
[0027] In addition, a sliding groove 23 is fixedly installed on the housing 1. A trapezoidal slider 24 is arranged at the bottom of the mounting plate 2. The trapezoidal slider 24 is slidably installed in the sliding groove 23.
[0028] Furthermore, it further includes a controller 25. A handle 26 and a button 27 are arranged on the housing 1. A pair of adapted inductive switches 28 are respectively arranged on the housing 1 and the guiding groove cam 7. The driving motor 6, the button 27 and the two inductive switches 28 are all electrically connected to the controller 25. In this utility model, the controller 27 adopts a single-chip microcomputer of the HD64F36109HV model of Renesas Corporation. Through the cooperation of the two inductive switches 28, it is used to sense the action of completing one marking and resetting, and then transmit a signal to the controller 25. The controller 25 controls the driving motor 6 to stop rotating.
[0029] Secondly, the reset element includes a tension spring 29. A mounting post 30 is fixedly installed on both the first clamping arm 3 and the second clamping arm 4. The two ends of the tension spring 29 are respectively installed on the two mounting posts 30.
[0030] The usage method of this utility model is as follows:
[0031] In the first step, place the upper ear tag 18 in the positioning groove 19 and it is abutted against the front end of the first clamping arm 3 by the elastic clamping piece 20. Place the lower ear tag 21 on the ear tag needle 22. As Figure 5As shown, the front ends of the first clamping arm 3 and the second clamping arm 4 are in an open state. Bring this ear tag pliers close to the animal's ear and press the control button 27 to activate this ear tag pliers.
[0032] The second step is as Figure 1 shown. Driven by the drive motor 6, the rotating shaft 5 rotates, the guide wheel 14 moves from the second arc-shaped groove 11 to the first arc-shaped groove 8, the mounting plate 2 moves away from the rotating shaft 5, and the front ends of the first clamping arm 3 and the second clamping arm 4 extend to the ear tagging position of the animal. At the same time, under the abutment of the distal ends of the first cam 16 and the second cam 17, the front ends of the first clamping arm 3 and the second clamping arm 4 approach each other, and the lower ear tag 21 passes through the animal's ear and is embedded in the upper ear tag 18, thus completing the tagging.
[0033] The third step is that after the tagging is completed, under the control of the controller 25, the rotating shaft 5 rotates, as Figure 4 shown. The proximal end of the first cam 16 abuts against the inner wall of the first clamping arm 3, and the proximal end of the second cam 17 abuts against the inner wall of the second clamping arm 4. Under the action of the reset element, the front ends of the first clamping arm 3 and the second clamping arm 4 move away from each other. At the same time, as Figure 5 shown, the guide wheel 14 moves from the first arc-shaped groove 8 to the second arc-shaped groove 11, the mounting plate 2 moves towards the rotating shaft 5, and the first clamping arm 3 and the second clamping arm 4 quickly retract into the housing 1, that is, the first clamping arm 3 and the second clamping arm 4 are quickly retracted after the tagging is completed.
[0034] In summary, since this utility model adopts cam drive, the cam can obtain a relatively high rotational speed under the drive of the motor, so that the tagging action and the retracting action of the ear tag pliers can be quickly completed, improving the tagging efficiency, and at the same time effectively avoiding the occurrence of situations such as the animal's ear having a notch and the tagging operation failing due to the struggle of the animal.
