DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] See also Figure 1-5 The present invention provides a technical solution: a tray delivery mechanism for an automatic tray loading machine for poultry eggs, comprising a shell 10, a control box 11 for controlling the operation of the device is installed on the side of the shell 10, a tray positioning frame 12 is fixedly installed on one side of the bottom of the shell 10, a poultry egg tray 14 is placed above the tray positioning frame 12, a conveying device 13 for delivering the poultry egg tray 14 to the automatic tray loading machine for loading is installed on the other side of the shell 10, a tray delivery assembly is installed on the side of the conveying device 13 inside the shell 10, and a tray delivery assembly is provided on one side of the tray positioning frame 12 inside the shell 10 for sucking and distributing the stacked poultry egg trays 14 to the tray delivery assembly.

[0023] In this embodiment, by installing a control box 11 on the side of the shell 10, receiving signals through sensors, and controlling the operation and stopping of the electric push rod 20, the cylinder 24, the flexible mechanical gripper 210 and the external motor through programming, the usability and reliability are improved. The tray positioning frame 12 arranged on one side of the bottom of the shell 10 ensures the accurate positioning of the poultry egg tray 14. The conveying device 13 installed on the other side realizes that the poultry egg tray 14 can be sent to the automatic tray loading device after passing through the tray separation component and the tray delivery component, which can be transported quickly and smoothly, thereby improving production efficiency. At the same time, the tray delivery component on the side of the conveying device 13 ensures that the poultry egg tray 14 is transported according to a predetermined path and rhythm, thereby ensuring the smooth progress of the tray loading work. The tray separation component arranged in the device can automatically absorb and distribute the stacked poultry egg trays 14, thereby avoiding the tediousness and errors of manual operation, and further improving the degree of automation and production efficiency. This mechanism not only improves the processing speed of the poultry egg trays 14, but also reduces labor intensity.

[0024] The stacking described above means that a plurality of egg trays 14 are engaged with each other through the grooves on their upper sides and stacked together in a vertical manner.

[0025] Specifically, the tray sub-assembly includes an electric push rod 20, which is fixedly mounted on the side of the tray positioning frame 12, a low-level sensor 21 is installed between the tray positioning frame 12 and the egg tray 14, a push rod extension end 22 is connected above the electric push rod 20, a mounting frame 23 is fixedly mounted on the upper end of the push rod extension end 22, a cylinder 24 is fixedly mounted on the mounting frame 23, a cylinder telescopic rod 25 is connected to one side of the cylinder 24, a fixed plate 26 is fixedly mounted on one end of the cylinder telescopic rod 25, a rotating cylinder 27 is installed on the fixed plate 26, a fixed rotating block 28 is provided at the rotating end of the side of the rotating cylinder 27, a grab bracket 29 is installed below the rotating block 28, flexible mechanical grippers 210 are installed at the four corners of the grab bracket 29, and a high-level sensor is installed in the middle position below the grab bracket 29.

[0026] In this embodiment, the tray sub-assembly is provided with an electric push rod 20, a low-position sensor 21, a cylinder 24, a rotating cylinder 27 and a flexible mechanical gripper 210 and other components. The electric push rod 20 is fixedly mounted on the side of the tray positioning frame 12. Through the cooperation of the low-position sensor 21, the position of the egg tray 14 can be accurately detected, thereby driving the electric push rod 20 to perform a precise pushing action. The mounting frame 23 installed above the push rod extension end 22 is fixed with a cylinder 24. The telescopic movement of the telescopic rod of the cylinder 24 drives the fixed plate 26 and the rotating cylinder 27 thereon to move. The rotating cylinder 27 The rotating end of the cylinder 27 is connected to the grab bracket 29 through the fixed rotating block 28. The flexible mechanical grippers 210 arranged at the four corners of the grab bracket 29 can gently and firmly grab the egg tray 14, avoiding damage to the tray during the grabbing process. At the same time, the high-position sensor installed in the middle position below the grab bracket 29 can ensure that the tray will not collide with other parts of the equipment during the grabbing process, further improving the accuracy and safety of the operation, realizing the automatic grabbing and distribution of the egg tray 14, and ensuring the stability and reliability of the entire process through high-precision sensors and mechanical components.

[0027] When the electric push rod 20 can control the cylinder 24 to move up and down, when the cylinder 24 is in the retracted position, the electric push rod 20 controls the cylinder 24 to move downward and move to the position just above the tray positioning frame 12. The tray positioning frame 12 fixes the egg tray 14 so that the raised position of the egg tray 14 is fixed, which is convenient for the flexible mechanical gripper 210 to grab. When the grab bracket 29 moves downward to the position of the egg tray 14, the push rod grabs the flexible mechanical gripper 210 on the bracket 29 to grab, and the egg tray 14 is grabbed horizontally. After the grabbing is completed, the electric push rod 20 moves upward. After moving to the top, the cylinder 24 is started, and the cylinder telescopic rod 25 extends to the farthest end. At this time The rotating cylinder 27 located on the rotating block 28 is started, and the grab bracket 29 on the rotating block 28 rotates 70°, and the egg tray 14 is rotated from a horizontal position to a 70° inclined position. After the rotation is completed, the flexible mechanical gripper 210 is released, and the egg tray 14 falls vertically. After falling, the rotating cylinder 27 rotates and resets, and the grab bracket 29 returns to the horizontal position. The cylinder 24 is started, and the cylinder telescopic rod 25 returns to the retracted position. The system starts a cyclic operation. After the stacked egg trays 14 are grabbed, the low-position sensor 21 on the tray positioning frame 12 transmits a signal, the electric push rod 20 is reset, and the tray distribution mechanism stops running. After the stacked trays are placed again, wait for startup.

[0028] Specifically, the feeding assembly includes a driving gear 30, which is rotatably mounted on the side of the outer shell 10. The side of the driving gear 30 penetrates the outer shell 10 and is rotatably connected to a connecting shaft 31. The connecting shaft 31 is rotatably mounted inside the outer shell 10. The side of the connecting shaft 31 is rotatably provided with a connecting shaft 2 32 inside the outer shell 10. The two ends of the connecting shaft 31 are fixedly sleeved with side sprockets 33 on the periphery, and the middle position of the connecting shaft 31 is fixedly sleeved with an intermediate sprocket 34 on the periphery. The connecting shaft 2 32 is also fixedly sleeved with side sprockets 33 and intermediate sprockets 34. The side sprockets 33 and the intermediate sprockets 34 fixedly sleeved on the connecting shaft 1 31 and the connecting shaft 2 32 are connected through a chain 35 for transmission. A receiving plate 36 is sleeved between the connecting shaft 1 31 and the connecting shaft 2 32 and between the side sprockets 33 and the intermediate sprocket 34, and a plurality of plastic paddles 37 are fixedly connected to the chain 35.

[0029] In the present embodiment, the delivery component adopts a chain transmission mechanism, which is rotatably installed on the side of the shell 10 by driving gear 1 30, and the connecting shaft 1 31 and the connecting shaft 2 32 are respectively fixedly mounted with side sprockets 33 and middle sprockets 34 on the connecting shaft 1 31 and the connecting shaft 2 32 inside the shell 10, and the side sprockets 33 and the middle sprockets 34 are connected together by a chain 35 to form a stable transmission chain, and a receiving plate 1 36 is mounted between the side sprockets 33 and the middle sprockets 34 between the connecting shaft 1 31 and the connecting shaft 2 32 to provide a stable support surface for the transportation of the poultry egg tray 14, and a plurality of plastic paddles 37 are fixedly connected to the chain 35. Driven by the chain 35, the plastic paddles 37 can smoothly push the poultry egg tray 14 along a predetermined path, thereby realizing the automatic transportation of the poultry egg tray 14, and also through the stability of the chain transmission and the flexibility of the plastic paddles 37, the stability and safety of the tray during transportation are ensured, thereby improving production efficiency and reducing operation difficulty.

[0030] Specifically, plastic paddles 37 are installed on the chain 35 at a certain distance. The chain 35 rotates slowly under the drive of the motor, wherein the front plastic paddle 37 forms a 45° wide angle with the adjacent plastic paddle 37. The farthest end of the travel of the grab bracket 29 is just above here, and the poultry egg tray 14 falls from above to here, that is, between the adjacent plastic paddles 37. The poultry egg tray 14 is transported forward under the protection of the plastic paddles 37 on the chain 35 and transported to the front end. The front end plastic paddle 37 supports the poultry egg tray 14 to a horizontal position, and the plastic paddle 37 moves downward from the middle gap. The poultry egg tray 14 is transported forward under the push of the belt transmission device 42, and the poultry egg tray 14 is transported forward in a horizontal direction.

[0031] Specifically, the conveying device 13 includes a driving gear 40, which is rotatably mounted on the outside of a section of the outer shell 10. A receiving plate 41 is fixedly mounted inside one end of the outer shell 10. A belt transmission device 42 is arranged on the surface of the receiving plate 41. The belt transmission device 42 is arranged corresponding to the receiving plate 1 36. A rotating shaft 43 is rotatably arranged on the side of the receiving plate 41.

[0032] In this embodiment, the conveying device 13 includes a driving gear 2 40, which is rotatably installed on the outside of one end of the outer shell 10. The driving gear 2 40 is driven by an external motor to provide a power source for the entire conveying device 13. A receiving plate 2 41 is fixedly installed inside the outer shell 10, and a belt transmission device 42 is arranged on its surface. This device corresponds to the receiving plate 1 36 in the tray delivery assembly, ensuring that the poultry egg tray 14 can smoothly transition from the tray delivery assembly to the conveying device 13. In the automatic egg tray loading machine, the belt transmission device 42 can accurately control the movement speed and direction of the tray, ensuring that the tray can be accurately transported to the next processing link. At the same time, the rotating shaft 43 rotatably arranged on the side of the receiving plate 2 41 provides the belt transmission device 42 with necessary support and adjustment functions, making the entire conveying device 13 more flexible and reliable, realizing the automated and efficient transportation of the poultry egg tray 14, improving production efficiency, and reducing operation difficulty and labor costs.

[0033] Specifically, the lower end surface of the plastic paddle 37 and the receiving plate 1 36 are in the same horizontal plane.

[0034] In the present embodiment, the plastic paddle 37 adopts a unique 6-shaped design, so that the poultry egg tray 14 can be stably placed on the top during transportation. At the same time, the lower end surface of the plastic paddle 37 is designed to be on the same horizontal plane as the receiving plate 36, ensuring that the poultry egg tray 14 can move steadily and smoothly along the predetermined path. At the same time, this also avoids the tilting or jamming of the poultry egg tray 14 due to uneven force during transportation, further improving the stability and reliability of the entire transportation process.

[0035] Specifically, the length of the belt transmission device 42 is greater than the second receiving plate 41 , and the height of the belt transmission device 42 is lower than the first receiving plate 36 .

[0036] In the present embodiment, the length of the belt transmission device 42 is designed to be greater than the receiving plate 41, thereby ensuring that there is sufficient space for smooth transportation and transfer of the egg tray 14 when it transitions from the tray delivery assembly to the conveyor 13. At the same time, the height of the belt transmission device 42 is set to be lower than the receiving plate 36, so that the tray can smoothly slide from the tray delivery assembly to the belt transmission device 42 without collision or jamming, thereby improving the continuity and stability of the tray transportation and avoiding noise and damage caused by tray collision. In addition, it also helps to reduce friction and resistance during operation, making the entire transportation process more efficient and smooth.

[0037] Specifically, the width of the long plate of the plastic paddle 37 is smaller than the distance between the belt transmission device 42 , and the width of the long plate of the plastic paddle 37 is smaller than the distance between the belt transmission device 42 and the inside of the housing 10 .

[0038] In the present embodiment, the width of the long plate of the plastic paddle 37 is carefully designed to be smaller than the distance between the belt drive device 42, and also smaller than the distance between the belt drive device 42 and the inside of the shell 10, thereby ensuring that the plastic paddle 37 can smoothly pass through the space between the two when pushing the egg tray 14 from the delivery assembly to the belt drive device 42 without getting stuck or colliding, thereby improving the continuity and stability of the delivery of the egg tray 14, and helping to reduce friction and resistance during operation, making the entire delivery process more efficient and smooth, and at the same time, avoiding noise and damage caused by collision between the paddle and the belt drive device 42 or the inside of the shell 10, thereby extending the service life of the equipment.

[0039] Specifically, the driving gear 2 40 is connected to the belt transmission device 42 .

[0040] In this embodiment, the driving gear 2 40 is connected to the belt transmission device 42 to ensure that the driving gear 2 40 can efficiently transmit its rotational power to the belt transmission device 42, thereby driving the belt for stable transmission. The external motor is used as a power source to provide stable and reliable power support for the belt transmission device 42. The belt transmission device 42, with its efficient and stable transmission characteristics, converts the rotational power of the driving gear 2 40 into the conveying power of the poultry egg tray 14, thereby realizing the automatic and continuous conveying of the tray, improving production efficiency, and ensuring the stability and safety of the poultry egg tray 14 during the conveying process. At the same time, it also simplifies the operation and maintenance process of the equipment and reduces labor and time costs.

[0041] Specifically, the driving gear 2 40 and the driving gear 1 30 are driven by an external motor.

[0042] In the present embodiment, the driving gear 2 40 and the driving gear 1 30 are driven by an external motor, which ensures that the power source of the entire mechanism is stable and reliable, and can efficiently drive the tray delivery component and the conveying device 13 to work. The external motor serves as a power source, and its strong driving force and stable operating characteristics provide sufficient power support for the driving gear 2 40 and the driving gear 1 30. Through the drive of the motor, the driving gear 2 40 can drive the belt transmission device 42 to perform stable transmission, and the driving gear 1 30 can drive the chain transmission system in the tray delivery component to work, thereby realizing the automatic and continuous transportation of the egg tray 14. This design not only improves production efficiency, but also ensures the stability and safety of the tray during transportation. At the same time, it also makes the structure of the entire mechanism more compact and reasonable, and reduces the complexity and maintenance cost of the equipment.

[0043] Specifically, the rotation angle of the rotating block 28 is 70°.

[0044] In this embodiment, the rotation angle of the rotating block 28 is set to 70° to ensure that the grasping bracket 29 can be rotated at a suitable angle under the drive of the rotating cylinder 27, thereby smoothly completing the grasping and releasing action of the egg tray 14.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
