[0001] The present invention relates to the technical field of coding machines, in particular to an egg coding machine. Background Art
[0002] Eggs are produced by hens and contain high-quality protein, fat, vitamins and other nutrients. When producing and packaging eggs, an egg coding machine is used to mark the basic information of the eggs on the surface of the eggshell to facilitate consumers to choose eggs based on the marked information.
[0003] In the prior art, the egg coding machine mainly consists of a conveyor belt for transporting eggs and a coding seat installed above the conveyor belt. When working, the conveyor belt transports the eggs to the bottom of the coding seat, and then the coding seat moves down to code the egg shell.
[0004] The above-mentioned and existing technologies have the following defects: during the coding process of eggs, eggs in the same batch may be of different sizes. Since the coding base is located at the same height during the coding process, it is easy to cause the situation where the coding cannot be clearly performed on smaller eggs.
[0005] Therefore, a kind of egg coding machine is proposed. Summary of the Invention
[0006] The purpose of the present invention is to solve the disadvantage that the coding seats are all located at the same height during the coding process, which easily makes it difficult to clearly code small eggs, and to propose an egg coding machine.

[0008] The effects achieved by the above components are as follows: by setting the coding structure, when coding the eggs, multiple coding seats can be located at different heights, so that eggs of different volumes can be clearly coded, ensuring the coding effect; by setting the drying structure, when the eggs are transported by the conveyor belt, when the eggs pass under the nozzle, the hot air discharged from the nozzle will dry the marks attached to the egg shells, avoiding the marks being touched and blurred or falling off during the subsequent transportation of the eggs, thereby improving the stability and clarity of the marks; by setting the guide structure, when the eggs roll out of the egg seat, the guide plate can guide the eggs, making it easier for the eggs to roll to the designated position.

When the coding seat contacts the larger egg, it will stop moving. Since the semi-threaded rod is slidably connected to the strip plate, the coding seat that codes the smaller eggs can continue to move downward until the coding seat contacts the smaller eggs. At this time, the coding seat is turned on to code the eggs.
[0011] Preferably, a round rod is slidably passed through the strip plate, the round rod is fixedly connected to the connecting plate, and the spring is sleeved on the circumferential surface of the round rod.
[0012] The effect achieved by the above components is that the round rod can prevent the connecting ring from rotating with the screw sleeve.
[0013] Preferably, a circumferential surface of the semi-threaded rod is fixedly equipped with a positioning ring, and the positioning ring is located above the strip plate.
[0014] The effect achieved by the above components is that the positioning ring can limit the position of the semi-threaded rod, thereby limiting the position of the coding seat, and preventing the coding seat from moving downward and affecting the eggs moving to the bottom of the coding seat.
[0015] Preferably, the surface sliding sleeve of the support plate is provided with a sliding tube, the outer wall of the sliding tube is fixedly equipped with a hollow plate, the hollow plate is fixedly connected to the nozzle, the upper surface of the mounting plate is fixedly equipped with a hot air pump, the exhaust end of the hot air pump is fixedly connected with a hose, and the hose is fixedly connected to the hollow plate.
[0016] The effect achieved by the above components is: during the operation of the conveyor belt, the hot air pump will run synchronously, and the hot air will be discharged into the hollow board through the hose, and then the hot air will be discharged by the nozzle. When the eggs pass under the nozzle, the hot air discharged by the nozzle will dry the marks attached to the egg shells, avoiding the marks from being touched and smudged or falling off during the subsequent transportation of eggs, thereby improving the stability and clarity of the marks.
[0017] Preferably, an insertion rod is slidably passed through the sliding tube, and a surface of the support plate is provided with a plurality of insertion holes adapted to the insertion rod.
[0018] The effect achieved by the above components is: when the insertion rod is inserted into the insertion hole, the insertion hole and the insertion rod cooperate to limit the position of the sliding tube, thereby limiting the position of the nozzle.
[0019] Preferably, one end of the insertion rod is fixedly equipped with a magnetic block, and the sliding tube is made of iron.

The rotation of the guide plate will drive the rotating rod to rotate. The rotating rod will twist the torsion spring.

Then the egg will roll down along the inner wall of the guide plate. The guide plate can guide the egg, making it convenient for the egg to roll to the designated position.
[0023] Preferably, the inner wall of the guide plate is fixedly equipped with a plurality of flexible strips.
[0024] The effect achieved by the above components is that the flexible strips can cushion the eggs and reduce the collision force between the eggs and the guide plates.
[0025] Preferably, a damping plate slidably connected to a fixed plate is fixedly mounted on the circumferential surface of the rotating rod, and a protrusion is fixedly mounted on the fixed plate relative to the damping plate.
[0026] The effect achieved by the above components is: the rotation of the rotating rod will cause the damping plate to slide along the surface of the fixed plate, and the friction between the damping plate and the fixed plate can damp the rotating rod, thereby preventing the guide plate from bouncing back and forth. When the egg rolls down, the torsion spring will use its own torsion force to rotate the rotating rod, and the rotation of the rotating rod will cause the damping plate to contact the protrusion. The cooperation between the damping plate and the protrusion can limit the rotation range of the rotating rod, thereby limiting the position of the guide plate when it does not contact the egg, ensuring that the guide plate can work normally.
[0027] Compared with the prior art, the advantages and positive effects of the present invention are:

[0040] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.
[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0042] like Figures 1-8 As shown, the present invention provides an egg coding machine, including a bracket 1, a conveyor belt 2 is sleeved on the surface of the bracket 1, a plurality of egg holders 3 are fixedly mounted on the surface of the conveyor belt 2, a mounting plate 4 is fixedly mounted on the upper surface of the bracket 1, and a through-beam photoelectric sensor 8 is fixedly mounted on the surface of the mounting plate 4. The present invention also includes: a coding structure 5 provided on the surface of the mounting plate 4 for coding eggs of different sizes, the coding structure 5 including an electric push rod 501 fixedly mounted on the surface of the mounting plate 4, a plurality of coding holders 504 for coding, and a spring 507 for ensuring that the coding holders 504 stably contact the eggs; a drying structure 6 provided on the upper surface of the bracket 1 for accelerating the drying of the marked code, the drying structure 6 including a support plate 61 fixedly mounted on the surface of the bracket 1 and a nozzle 64 for discharging hot air; and a guide structure 7 provided on the lower surface of the bracket 1 for guiding the eggs, the guide structure 7 including a fixing plate 71 fixedly mounted on the lower surface of the bracket 1 and a guide plate 73 for receiving fallen eggs.
[0043] The output end of the electric push rod 501 is fixedly equipped with a strip plate 502, and a half-threaded rod 503 is slidably passed through the strip plate 502. The lower end of the half-threaded rod 503 is fixedly connected to the coding seat 504, and the circumferential surface of the half-threaded rod 503 is threadedly connected with a screw sleeve 505. The lower end of the screw sleeve 505 is rotatably connected with a connecting ring 506, which is sleeved on the circumferential surface of the half-threaded rod 503. The two ends of the spring 507 are respectively fixedly connected to the connecting ring 506 and the strip plate 502. The circumferential surface of the screw sleeve 505 is fixedly equipped with a paddle 508. When the output end of the electric push rod 501 extends, the strip plate 502 will move downward, and the movement of the strip plate 502 will cause the spring 507 to move synchronously. The connecting ring 506 follows the spring 507 to drive the screw sleeve 505 to move, and the screw sleeve 505 will drive the half-threaded rod 503 to move, and the half-threaded rod 503 will drive the coding seat 504 to move downward. After contacting the egg of larger volume, it will stop moving. Since the half-threaded rod 503 is slidably connected to the strip plate 502, the coding seat 504 for coding the egg of smaller volume can continue to move down until the coding seat 504 contacts the egg of smaller volume. At this time, the coding seat 504 is opened to code the egg. A round rod 509 is slidably passed through the strip plate 502. The round rod 509 is fixedly connected to the connecting plate. The spring 507 is sleeved on the circumferential surface of the round rod 509. The round rod 509 can prevent the connecting ring 506 from rotating with the screw sleeve 505. The circumferential surface of the half-threaded rod 503 is fixedly equipped with a positioning ring 510. The positioning ring 510 is located above the strip plate 502. The positioning ring 510 can limit the position of the half-threaded rod 503, thereby limiting the position of the coding seat 504, and avoiding the situation that the coding seat 504 moves downward and affects the egg to move to the bottom of the coding seat 504.
[0044] The surface of the support plate 61 is slidably covered with a sliding tube 62, and the outer wall of the sliding tube 62 is fixedly equipped with a hollow plate 63, and the hollow plate 63 is fixedly connected to the nozzle 64. The upper surface of the mounting plate 4 is fixedly equipped with a hot air pump 65, and the exhaust end of the hot air pump 65 is fixedly connected to a hose 66, and the hose 66 is fixedly connected to the hollow plate 63. During the operation of the conveyor belt 2, the hot air pump 65 will run synchronously, and the hot air will be discharged into the hollow plate 63 through the hose 66, and then the hot air will be discharged by the nozzle 64. When the egg passes under the nozzle 64, the hot air discharged by the nozzle 64 will dry the mark attached to the egg shell , to avoid the situation where the mark is hit and smudged or falls off during the subsequent transportation of eggs, thereby improving the stability and clarity of the mark. A rod 68 slides through the sliding tube 62, and a plurality of sockets 67 are provided on the surface of the support plate 61 to match the rod 68. The rod 68 is inserted into the socket 67. The socket 67 cooperates with the rod 68 to limit the position of the sliding tube 62, thereby limiting the position of the nozzle 64. One end of the rod 68 is fixedly equipped with a magnetic block 69. The sliding tube 62 is made of iron. After the magnetic block 69 is sucked onto the outer wall of the sliding tube 62, it can prevent the rod 68 from falling out from the inner wall of the socket 67.
[0045] The fixing plate 71 is connected to the rotating rod 72 in rotation, and the guide plate 73 is fixedly installed on the circumferential surface of the rotating rod 72. The circumferential surface of the rotating rod 72 is provided with a torsion spring 74. The two ends of the torsion spring 74 are fixedly connected to the fixing plate 71 and the rotating rod 72 respectively. When the egg rolls down from the egg holder 3, it will fall onto the inner wall of the guide plate 73. The guide plate 73 will rotate due to the impact. The rotation of the guide plate 73 will drive the rotating rod 72 to rotate. The rotating rod 72 will twist the torsion spring 74. The torsion spring 74 will use its own torsion force to buffer the rotating rod 72, thereby buffering the guide plate 73 and then buffering the egg. Then the egg will roll downward along the inner wall of the guide plate 73. The guide plate 73 can guide the egg to facilitate the egg to roll to the specified position. The inner wall of the guide plate 73 is fixedly equipped with a plurality of flexible strips 75. The flexible strips 75 The rotation of the rotating rod 72 will cause the damping plate 76 to slide along the surface of the fixed plate 71. The friction between the damping plate 76 and the fixed plate 71 can damp the rotating rod 72, thereby preventing the guide plate 73 from bouncing back and forth. When the egg rolls down, the torsion spring 74 will use its own torsion to rotate the rotating rod 72. The rotation of the rotating rod 72 will cause the damping plate 76 to contact the bump 77. The damping plate 76 and the bump 77 can cooperate to limit the rotation range of the rotating rod 72, thereby limiting the position of the guide plate 73 when it does not contact the egg, ensuring that the guide plate 73 can work normally.
[0046] The overall working principle is that when eggs need to be coded, the eggs are placed on the egg holder 3, and then the egg holder 3 and the eggs are transported by the conveyor belt 2. When the eggs move to the through-beam photoelectric sensor 8, the eggs will block the through-beam photoelectric sensor 8. At this time, the conveyor belt 2 is temporarily running, the output end of the electric push rod 501 begins to extend, the strip plate 502 will move downward, and the movement of the strip plate 502 will cause the spring 507 to move synchronously. The connecting ring 506 follows the spring 507 to drive the screw sleeve 505 to move, and the screw sleeve 505 will drive the semi-threaded rod When the coding seat 504 moves, the semi-threaded rod 503 will drive the coding seat 504 to move down. When the coding seat 504 contacts the larger egg, it will stop moving. Since the semi-threaded rod 503 is slidably connected to the strip plate 502, the coding seat 504 for coding the smaller egg can continue to move down until the coding seat 504 contacts the smaller egg. At this time, the coding seat 504 is turned on to code the egg. During this process, the spring 507 will use its own elastic force to ensure that the coding seat 504 is stably in contact with the egg, ensuring the coding effect. When the elastic force of the spring 507 is adjusted according to the egg specifications, the screw sleeve 505 is rotated by means of the pick 508, and the screw sleeve 505 moves with the help of the thread. When the screw sleeve 505 moves upward, the spring 507 will continue to be stretched. At this time, the elastic force of the spring 507 will become larger. When the screw sleeve 505 moves downward, the elastic force of the spring 507 will become smaller, thereby being able to flexibly adjust the elastic force of the spring 507, that is, to ensure that the coding seat 504 is in normal contact with the egg, and to avoid the situation where the egg is damaged due to excessive elastic force. During the adjustment process, the round rod 509 can prevent the connecting ring 504 from being 06 rotates with the screw sleeve 505, and the positioning ring 510 can limit the position of the semi-threaded rod 503, thereby limiting the position of the coding seat 504, and preventing the coding seat 504 from moving downward and affecting the eggs moving to the bottom of the coding seat 504. After the coding is completed, the output end of the electric push rod 501 is controlled to shrink, and the coding seat 504 will move upward, and then the conveyor belt 2 continues to run, and the coded eggs are moved away from under the coding seat 504. With the help of the through-beam photoelectric sensor 8, the running state of the conveyor belt 2 can be conveniently controlled, thereby improving the intelligence of the coding machine.
[0047] During the operation of the conveyor belt 2, the hot air pump 65 will run synchronously, and the hot air will be discharged into the hollow plate 63 through the hose 66, and then the hot air will be discharged by the nozzle 64. When the eggs pass under the nozzle 64, the hot air discharged by the nozzle 64 will dry the mark attached to the egg shell, avoiding the mark being touched and blurred or falling off during the subsequent transportation of the eggs, thereby improving the stability and clarity of the mark. When it is necessary to adjust the drying temperature, pull the magnetic block 69 to pull the rod 68 out of the socket 67, and then slide the slide tube 62 along the surface of the support plate 61. , adjust the height of the hollow plate 63, and then adjust the height of the nozzle 64. When the nozzle 64 moves upward, the nozzle 64 is farther away from the eggs, so the drying temperature will drop. When the nozzle 64 moves downward, the drying temperature will rise, thereby improving the flexibility of drying the egg marks. After the adjustment is completed, the rod 68 is inserted into the socket 67. The socket 67 and the rod 68 cooperate to limit the position of the slide tube 62, thereby limiting the position of the nozzle 64. The magnetic block 69 will be sucked on the outer wall of the slide tube 62, thereby preventing the rod 68 from escaping from the inner wall of the socket 67.
[0048] When the egg rolls down from the egg holder 3, it will fall onto the inner wall of the guide plate 73. At this time, the flexible strip 75 can cushion the egg and reduce the collision force between the egg and the guide plate 73. At the same time, the guide plate 73 will rotate due to the impact. The rotation of the guide plate 73 will drive the rotating rod 72 to rotate. The rotating rod 72 will twist the torsion spring 74. The torsion spring 74 will cushion the rotating rod 72 with its own torsion force, thereby cushioning the guide plate 73 and further cushioning the egg. The rotation of the rotating rod 72 will also cause the damping plate 76 to slide along the surface of the fixed plate 71. There is a gap between the damping plate 76 and the fixed plate 71. The friction force can damp the rotating rod 72, thereby preventing the guide plate 73 from bouncing back and forth. Then the egg will roll downward along the inner wall of the guide plate 73. The guide plate 73 can guide the egg and facilitate the egg to roll to the designated position. When the egg rolls down, the torsion spring 74 will use its own torsion force to rotate the rotating rod 72 in the opposite direction. The rotation of the rotating rod 72 will cause the damping plate 76 to contact the protrusion 77. The damping plate 76 and the protrusion 77 can cooperate to limit the rotation range of the rotating rod 72, thereby limiting the position of the guide plate 73 when it does not contact the egg, ensuring that the guide plate 73 can work normally.
