Technical Field
[0001] This utility model relates to the field of salted duck egg technology, specifically a salted duck egg production and processing brine injection pickling machine. Background Technology
[0002] Salted duck eggs are processed eggs made primarily from fresh duck eggs through a pickling process. They are rich in nutrients, including fat, protein, various amino acids, calcium, phosphorus, iron, trace elements, and vitamins essential for the human body. They are easily absorbed, have a moderate saltiness, and are suitable for all ages. The eggshells are bluish-green, with a smooth, round appearance, hence the name "green egg." Salted duck eggs are a type of processed egg with a unique flavor and convenient consumption. They are a delicious side dish, with an appealing color, aroma, and taste. Since duck eggs are the main raw material for salted duck egg processing, a brine injection pickling machine is needed for salted duck egg production and processing.
[0003] When processing salted duck eggs, operators need to inject brine into them. However, the positioning and feeding of duck eggs are often done manually. This increases the labor intensity of the operators and can also reduce the quality of the salted duck eggs due to inaccurate positioning. In addition, the automation level is low and the connection between the various processes is not smooth enough, which may reduce the efficiency of salting duck eggs. Summary of the Invention
[0004] The purpose of this utility model is to provide a brine injection pickling machine for salted duck egg production and processing, in order to solve the problem mentioned in the background art that when operators produce and process salted duck eggs, they need to inject brine into them. However, when positioning and feeding the duck eggs, manual positioning and feeding are often used. This operation method increases the labor intensity of the operators, and the quality of pickling duck eggs may be reduced due to inaccurate positioning. In addition, the degree of automation is low, and the connection between each process is not smooth enough, which may reduce the efficiency of pickling duck eggs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a salted duck egg production and processing brine injection pickling machine, comprising a base plate, a strip groove on the top of the base plate, a lead screw rotatably mounted inside the strip groove, a sliding sleeve threaded onto the surface of the lead screw, a storage plate fixedly mounted on the top of the sliding sleeve, storage grooves equidistantly opened on the top of the storage plate, a sliding groove on one end of the storage plate, a bidirectional threaded rod rotatably mounted inside the sliding groove, threaded sleeves threaded onto both sides of the surface of the bidirectional threaded rod, a moving rod fixedly mounted on one end of the threaded sleeve, and a positioning plate fixedly mounted on the top of each moving rod.
[0006] Preferably, an adjusting motor is fixedly installed on one side of the base plate, the output end of the adjusting motor passes through the base plate and is fixedly connected to one side of the lead screw, and a rotary motor is fixedly installed on one side of the shelf, the output end of the rotary motor passes through the shelf and is fixedly connected to one side of the bidirectional threaded rod.
[0007] Preferably, a processing chamber is fixedly installed on the top of the base plate, and guide rods are movably installed at both ends of the top of the processing chamber. The bottom of the guide rods penetrates through the processing chamber and extends into the interior of the processing chamber. A liquid storage box is fixedly installed at the bottom of the guide rods, and injection needles are fixedly installed at equal intervals at the bottom of the liquid storage box. The top of the injection needles penetrates through the liquid storage box and extends into the interior of the liquid storage box.
[0008] Preferably, a storage box is fixedly installed on the top of the liquid storage box, and a round tube is fixedly installed on the top of the storage box, with the bottom of the round tube penetrating the storage box and extending to the inner surface of the storage box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This salted duck egg brine injection pickling machine, in daily use, involves the operator placing the duck eggs inside the storage trough and then starting the rotary motor. The rotation of the rotary motor causes the bidirectional threaded rod to rotate, which in turn causes the threaded sleeve to slide inside the sliding groove. The sliding groove then causes the moving rod to slide, which in turn causes the positioning plate to slide, thus positioning the duck eggs. Simultaneously, the adjustment motor is started, causing the lead screw to rotate. This leads the lead screw to slide inside the strip groove, which in turn causes the storage plate and the duck eggs on top to slide until the duck eggs are positioned below the injection needle. This operation method can automatically position and feed the duck eggs, thereby reducing the labor intensity of the operator and improving the quality of the pickled duck eggs.
[0013] This salted duck egg production and processing brine injection pickling machine operates as follows: The operator starts the pneumatic cylinder, which causes the injection pump to slide. The injection pump then moves the storage tank, which in turn moves the liquid storage box, thus guiding the injection needle into the duck egg. Simultaneously, the injection pump is activated, drawing brine through the suction pipe. The brine then flows through the connecting pipe into the liquid storage box and is automatically injected into the duck egg through the injection needle. This highly automated operation allows for smoother transitions between processes, thereby improving the efficiency of duck egg pickling. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: a salted duck egg production and processing brine injection pickling machine, including a base plate 1, a strip groove 2 on the top of the base plate 1, a lead screw 3 rotatably installed inside the strip groove 2, and a sliding sleeve 4 threaded onto the surface of the lead screw 3. When the lead screw 3 rotates, it drives the sliding sleeve 4 to slide inside the strip groove 2, thereby adjusting the position of the sliding sleeve 4. A placement plate 6 is fixedly installed on the top of the sliding sleeve 4, and placement grooves 7 are equidistantly opened on the top of the placement plate 6. When the sliding sleeve 4 slides, it drives the placement plate 6 to slide, and the placement grooves 7 can hold duck eggs. A sliding groove 8 is opened at one end of the placement plate 6, and a double-threaded rod 9 is rotatably installed inside the sliding groove 8. Both sides of the surface of the double-threaded rod 9 are threaded with sleeves 10. When the double-threaded rod 9 rotates, it drives the two sleeves 10 to slide inside the sliding groove 8. The position of the threaded sleeve 10 can be adjusted by moving it in the opposite direction. A moving rod 12 is fixedly installed at one end of the threaded sleeve 10, and a positioning plate 13 is fixedly installed at the top of the moving rod 12. When the threaded sleeve 10 slides, it will drive the moving rod 12 to slide, which in turn will drive the positioning plate 13 to slide, thus positioning the duck egg. An adjusting motor 5 is fixedly installed on one side of the base plate 1. The output end of the adjusting motor 5 passes through the base plate 1 and is fixedly connected to one side of the threaded rod 3. When the adjusting motor 5 is running, it will cause the threaded rod 3 to rotate, thereby improving the adjustment efficiency of the sliding sleeve 4. A rotary motor 11 is fixedly installed on one side of the shelf 6, and the output end of the rotary motor 11 passes through the shelf 6 and is fixedly connected to one side of the bidirectional threaded rod 9. When the rotary motor 11 is running, it will cause the bidirectional threaded rod 9 to rotate, thereby improving the adjustment efficiency of the threaded sleeve 10.
[0021] A processing chamber 14 is fixedly installed on the top of the base plate 1. Guide rods 15 are movably installed at both ends of the top of the processing chamber 14. The bottom of the guide rods 15 penetrates the processing chamber 14 and extends into the interior of the processing chamber 14. A liquid storage box 16 is fixedly installed at the bottom of the guide rods 15. When the liquid storage box 16 slides, it will cause the guide rods 15 to slide inside the processing chamber 14. Due to the design of the guide rods 15, their movement is more stable. Injection needles 17 are fixedly installed at equal intervals at the bottom of the liquid storage box 16. The top of the injection needles 17 penetrates the liquid storage box 16 and extends into the interior of the liquid storage box 16. When the liquid storage box 16 slides, it will cause the injection needles 17 to slide until they are placed inside the duck egg, at which point saline can be injected. A storage tank 18 is fixedly installed on the top of the liquid storage box 16. A round tube 19 is fixedly installed on the top of the storage tank 18. The bottom of the round tube 19 penetrates the storage tank 18 and extends into the storage tank 16. The inner surface of the storage tank 18 allows brine to be injected into the storage tank 18 through the round tube 19. The storage tank 18 stores the brine. A syringe pump 20 is fixedly installed on the top of the storage tank 18. Connecting pipes 21 are fixedly installed at both ends of the syringe pump 20. The bottom of the connecting pipe 21 passes through the liquid storage box 16 and extends to the inner surface of the liquid storage box 16. A suction pipe 22 is fixedly installed on one side of the syringe pump 20, and the bottom of the suction pipe 22 passes through the storage tank 18 and extends into the storage tank 18. When the syringe pump 20 is running, it draws brine from the storage tank 18 through the suction pipe 22 and delivers it to the inside of the liquid storage box 16 through the connecting pipe 21. A pneumatic cylinder 23 is fixedly installed on the top of the processing chamber 14, and the output end of the pneumatic cylinder 23 passes through the processing chamber 14 and is fixedly connected to the top of the syringe pump 20. When the pneumatic cylinder 23 is running, it causes the syringe pump 20 to slide, thereby improving the adjustment efficiency.
[0022] Working principle: The operator places the duck egg inside the placement trough 7 and then starts the rotary motor 11. The operation of the rotary motor 11 causes the bidirectional threaded rod 9 to rotate. At this time, the bidirectional threaded rod 9 drives the threaded sleeve 10 to slide inside the slide groove 8. Subsequently, the slide groove 8 drives the moving rod 12 to slide, and then the moving rod 12 drives the positioning plate 13 to slide, thus positioning the duck egg. At the same time, the adjusting motor 5 is started. The operation of the adjusting motor 5 causes the lead screw 3 to rotate. Subsequently, the lead screw 3 drives the sliding sleeve 4 to slide inside the strip groove 2, and then the sliding sleeve 4 drives the placement trough 13 to slide. The plate 6 and the duck egg on top slide until the duck egg is below the injection needle 17. Then, the pneumatic cylinder 23 is activated. The operation of the pneumatic cylinder 23 will cause the injection pump 20 to slide. The injection pump 20 will then drive the storage box 18 to slide. Subsequently, the storage box 18 will drive the liquid storage box 16 to slide, thereby driving the injection needle 17 to the inside of the duck egg. At the same time, the injection pump 20 is activated. The operation of the injection pump 20 will draw brine through the suction pipe 22. The brine will then enter the inside of the liquid storage box 16 through the connecting pipe 21, and then be automatically injected into the inside of the duck egg through the injection needle 17.
