[0058] In this embodiment, the female mark clamp positioning groove 119 includes a female mark clamp groove-shaped structure 1191, a limiting guide block 1192 and a positioning pin 1193. The bottom of the female mark clamp groove-shaped structure 1191 is provided with a limiting guide block 1192 and a positioning pin 1193 for limiting the position and angle of the female mark to be printed.

[0059] It should be noted that the position and angle of the mother mark to be punched can be limited by the limiting guide block 1192 and the positioning pin 1193 so that the mother mark to be punched meets the punching requirements.

[0060] The marking mechanism 1 includes a switch device 12, which is mounted on a frame 11 and is used to control a drive device 13;

[0061] In this embodiment, the switch device 12 includes a touch switch 120, a mounting plate 121, a fixed shaft 122, a rocker arm 123, a touch rod 124, a screw fixing block 125, a spring limit block 126, a screw 127, a spring 128 and a limit pin 129.

[0062] The mounting plate 121 is mounted on the main board 116 by bolts, and the mounting plate 121 is movably connected to the swing rod 123 through the fixed shaft 122. A limit pin 129 is arranged on one side of the swing rod 123, and a touch rod 124 is arranged on the end of the swing rod 123. A screw fixing block 125 and a spring limit block 126 are arranged in the middle of the swing rod 123, and a screw 127 is installed on the screw fixing block 125, wherein a touch switch 120 is arranged on the side of the screw 127, and the touch switch 120 is arranged on the mounting plate 121, and a spring 128 is arranged on the spring limit block 126, and the spring 128 is connected to the mounting plate 121, wherein the screw 127 drives the swing rod 123 to rotate around the fixed shaft 122 by touching the touch rod 124, thereby squeezing the touch switch 120.

[0063] It should be noted that the touch rod 124 drives the swing rod 123 to rotate around the fixed shaft 122 and squeezes the touch switch 120 once through the screw 127, thereby forming a switch action.

[0064] Specifically, use the back of your hand to gently touch the touch rod 124, so that the swing rod 123 rotates around the fixed axis 122 toward the touch switch 120. During the rotation of the swing rod 123, the screw 127 is driven to move, so that the screw 127 squeezes the touch switch 120. At this time, the drive motor 131 is started and the output shaft of the drive motor 131 starts to rotate.

[0065] The marking mechanism 1 includes a driving device 13, and the driving device 13 is mounted on the frame 11;

[0066] In this embodiment, the driving device 13 includes a driving motor 131 and a pinion 132 . The driving motor 131 is mounted on the main board 116 , and the pinion 132 is mounted on the output shaft of the driving motor 131 .

[0067] The marking mechanism 1 includes a gear device 14, which is mounted on the frame 11 and driven to rotate by the driving device 13;

[0068] In this embodiment, the gear device 14 includes a large gear 141 , a bearing 142 , a mounting shaft 143 , an inner pressure plate 144 , an outer pressure plate 145 and a spacer 146 .

[0069] The small gear 132 is meshed with the large gear 141, and the large gear 141 is connected to the mounting shaft 143 through a bearing 142. The mounting shaft 143 is mounted on the main board 116. The large gear 141 is connected to the mounting shaft 143 through an inner pressure plate 144. An outer pressure plate 145 is arranged on the periphery of the inner pressure plate 144, and a spacer sleeve 146 is arranged in the gap between the large gear 141 and the mounting shaft 143.

[0070] It should be noted that an eccentric hole is provided on the large gear 141 , and the first connecting shaft 151 is installed at the eccentric hole.

[0071] It should be noted that the output shaft of the driving motor 131 rotates to drive the pinion gear 132 to rotate. Since the pinion gear 132 is meshed with the large gear 141 , the rotation of the pinion gear 132 drives the large gear 141 to rotate.

[0072] The marking mechanism 1 includes a connecting rod device 15.

[0073] In this embodiment, the connecting rod device 15 includes a first connecting shaft 151, a fisheye ball head connecting rod 152, a second connecting shaft 153, a joint 154, a pull rod 155 and a guide bearing 156. One end of the fisheye ball head connecting rod 152 is connected to the eccentric hole of the large gear 141 through the first connecting shaft 151, and the other end of the fisheye ball head connecting rod 152 is connected to the joint 154 through the second connecting shaft 153. The joint 154 is installed on the pull rod 155, and the pull rod 155 is movably connected in the guide bearing 156. The guide bearing 156 is installed on the outer end surfaces of the main plate 116 and the sub-plate 117.

[0074] It should be noted that both ends of the fisheye ball head connecting rod 152 are freely rotatable bearing structures, and the rotation of the large gear 141 can be converted into the linear motion of the pull rod 155 through the gear device 14 and the connecting rod device 15 .

[0075] It should be noted that the output shaft of the driving motor 131 rotates to drive the pinion 132 to rotate. Since the pinion 132 is meshed with the large gear 141, the rotation of the pinion 132 drives the large gear 141 to rotate. During the rotation of the large gear 141, the pull rod 155 moves linearly under the guidance of the guide bearing 156 through the first connecting shaft 151, the fisheye ball head connecting rod 152, the second connecting shaft 153 and the joint 154. The linear movement of the pull rod 155 drives the mark pin seat 16 and the mark pin 17 to move linearly.

[0076] The marking mechanism 1 includes a marking needle seat 16 , which includes a connecting plate 161 and a push rod 162 . The connecting plate 161 is fixed to the head of the pull rod 155 . The push rod 162 is arranged at the lower end of the connecting plate 161 , and the marking needle 17 is installed on the push rod 162 .

[0077] It should be noted that the marking needle 17 first pushes into the male mark to be marked, and when the large gear 141 rotates to a half-circle position, the male mark to be marked pierces the piglet ear tag and is driven into the female mark to be marked. When the large gear 141 rotates to a full circle position, the marking needle 17 returns to the initial position to complete a marking process. At this time, the second male mark in the male mark clamp 2 automatically enters the position to be marked and the second female mark in the female mark clamp 3 automatically enters the position to be marked. When the breeder continues to grab the piglets and repeats the above marking operation, continuous marking can be completed.

[0078] In this embodiment, multiple male labels are arranged in the male label clamp 2, among which the bottom male label is the male label to be printed, and multiple female labels are arranged in the female label clamp 3, among which the bottom female label is the female label to be printed. The marking needle 17, the male label to be printed and the female label to be printed are located on the same axis.

[0079] It should be noted that the switch device 12 controls the drive device 13, and when the switch is triggered once, the drive device 13 drives the large gear 141 to rotate once. The initial position of the marking needle 17 is at the farthest end, and at this time, the pull rod 155 is extended to the longest length.

[0080] A protective cover 4 is provided on the outer side of the marking mechanism 1;

[0081] In this embodiment, a protective cover mounting hole is provided on the frame 11 , and the protective cover 4 is provided on the outside of the marking mechanism 1 , so that the marking mechanism 1 is protected by the protective cover 4 .

[0082] It should be noted that the protective cover 4 includes a sheet metal protective cover 41 and a transparent protective cover 42 . The sheet metal protective cover 41 is installed on the frame 11 , and the transparent protective cover 42 is arranged at the end of the sheet metal protective cover 41 .

[0083] In order to better demonstrate the continuous marking process of piglet ear tags, this embodiment now provides a continuous marking method of a continuous marking device for piglet ear tags as described above, including the following steps:

[0084] S1: The breeder picked up a piglet and placed the piglet’s ear into the threshing area;

[0085] S2: Use the back of your hand to gently touch the touch rod 124, so that the swing rod 123 rotates around the fixed axis 122 toward the touch switch 120. During the rotation of the swing rod 123, the screw 127 is driven to move, so that the screw 127 squeezes the touch switch 120. At this time, the drive motor 131 is started and the output shaft of the drive motor 131 starts to rotate;

[0086] S3: The output shaft of the driving motor 131 rotates to drive the pinion 132 to rotate. Since the pinion 132 is meshed with the large gear 141, the rotation of the pinion 132 drives the large gear 141 to rotate. During the rotation of the large gear 141, the pull rod 155 moves linearly under the guidance of the guide bearing 156 through the first connecting shaft 151, the fisheye ball head connecting rod 152, the second connecting shaft 153 and the joint 154. The linear movement of the pull rod 155 drives the mark needle seat 16 and the mark needle 17 to move linearly as well.

[0087] S4: The marking needle 17 first pushes into the male mark to be marked. When the large gear 141 rotates to a half-circle position, the male mark to be marked pierces the piglet ear tag and is driven into the female mark to be marked. When the large gear 141 rotates to a full circle position, the marking needle 17 returns to the initial position to complete a marking process. At this time, the second male mark in the male mark clamp 2 automatically enters the position to be marked and the second female mark in the female mark clamp 3 automatically enters the position to be marked. When the breeder continues to grab the piglets and repeats the above marking operation, continuous marking can be completed.

[0088] Therefore, single-person operation can be achieved for continuous and stable ear tagging, which greatly improves the efficiency of large-scale ear tagging of piglets in breeding enterprises and reduces the workload of breeders. At the same time, the consistency of marking force and marking position can be maintained, and the piglet ear tagging work can be avoided from being affected by the breeder's fatigue, marking force changes or proficiency, thereby reducing the damage to the piglets during the marking process. Therefore, the piglet ear tag continuous marking device is of great significance to promoting the development of the breeding industry.
