Detailed Embodiments

[0018] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0019] This application provides an egg tray conveying mechanism and an egg palletizing machine. Please refer to Figures 1 - 7 : including; A housing 1; A first transmission member 2; A second transmission member 3; A limiter 4 for restricting the first transmission member 2 and the second transmission member 3 to transmit along a specified trajectory; A balancing member 5. The rotation axis of the balancing member 5 is hinged to the first transmission member 2. The edge of the balancing member 5 is engaged with the second transmission member 3. The balancing member 5 makes a circular revolution along the first transmission member 2, and the balancing member 5 does not rotate by itself during the revolution; A supporting plate 6, which is rotatably installed on the balancing member 5 and is used to lift the egg tray when moving upward and can release the egg tray when moving downward; A power assembly 7 for driving the first transmission member 2 and the second transmission member 3 to transmit at the same linear speed.

[0020] Specifically, in actual application, the power assembly 7 drives the first transmission member 2 and the second transmission member 3 to operate at the same linear speed. When the moving direction of the balancing member 5 changes, the transmission speed of the second transmission member 3 is faster than that of the first transmission member 2. The extra moving distance of the second transmission member 3 offsets the deflection of the balancing member 5. While driving the supporting plate 6 to move, self-balancing is achieved; The conveying mechanism 8 conveys the single-layer egg tray to the position where the supporting plate 6 moves upward. Through the action of the supporting plate 6, the single-layer placed egg tray is lifted upward until it moves to the other side of the equipment for a falling action. When the supporting plate 6 moves downward, through the support of the conveying mechanism 9, the egg trays can be stacked up. After stacking to the specified number of layers, the stacked egg trays are conveyed to another working station; Through the action of the power assembly 7, while providing a power source for the first transmission member 2 and the second transmission member 3, the moving speed ratio between the first transmission member 2 and the second transmission member ; can be adjusted.

[0021] Refer to Figure 1 , Figure 2 , Figure 3 , a special-shaped fixing block 51 is installed on one side of the balancing member 5. A connecting rod 52 is rotatably installed at the horizontal position of the special-shaped fixing block 51. The supporting plate 6 is installed on the connecting rod 52. A torsion spring 53 is installed between the supporting plate 6 and the special-shaped fixing block 51. The torsion spring 53 drives the supporting plate 6 to have a tendency to rotate downward.

[0022] Specifically in practical applications, the special-shaped fixing block 51 is fixedly connected to the balancing component 5. Through the action of the connecting rod 52, when the supporting plate 6 moves downward and touches an obstacle, it can automatically turn upward, facilitating the downward movement of the supporting plate 6. Through the action of the torsion spring 53, the supporting plate 6 moves stably.

[0023] Embodiment 1 of the first transmission component 2, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the first transmission component 2 is an outer ring chain 21, the second transmission component 3 is an inner ring chain 31, the balancing component 5 is a sprocket 54, a support shaft 541 is provided at the center of the sprocket 54, one end of the support shaft 541 is fixedly connected to the outer ring chain 21, the outer ring of the sprocket 54 meshes with the inner ring chain 31, and the first transmission component 2 and the second transmission component 3 are in different planes.

[0024] Specifically in practical applications, a support shaft 541 is provided at the center of the sprocket 54. Through the action of the support shaft 541, the sprocket 54 can rotate around the support shaft 541 as the axis. The moving speeds of the outer ring chain 21 and the inner ring chain 31 are the same. However, when the moving direction of the sprocket 54 changes, since the turning radius of the inner ring chain 31 is smaller, the displacement of the inner ring chain 31 will be faster than that of the outer ring chain 21 at the same moving speed, and the resulting distance difference exactly offsets the active rotation of the sprocket 54, making the sprocket 54 and the supporting plate 6 in a horizontal position.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 , multiple limiters 4 are provided and are respectively located on both sides of the outer ring chain 21 and the inner ring chain 31 to limit the moving paths of the outer ring chain 21 and the inner ring chain 31. The different position spacings between the outer ring chain 21 and the inner ring chain 31 are equal; the outer ring chain 21 and the inner ring chain 31 are divided into a vertical part 211 and a horizontal part 212, and the included angle between the vertical part 211 and the horizontal part 212 is 90 degrees. The position where the vertical part 211 and the horizontal part 212 are connected is a buffer part 213, and the buffer part 213 is an irregular arc.

[0026] Specifically, in actual applications, the outer ring chain 21 and the inner ring chain 31 have stable moving paths through the action of the stopper 4. By setting the equal distances between different positions of the outer ring chain 21 and the inner ring chain 31, the movement of the sprocket 54 becomes more stable. When the sprocket 54 moves on the vertical part 211 and the horizontal part 212, the moving speeds of the outer ring chain 21 and the inner ring chain 31 are the same; when the sprocket 54 moves to the buffer part 213, since the turning radius of the inner ring chain 31 is smaller, the displacement of the inner ring chain 31 will be faster than that of the outer ring chain 21 at the same moving speed, and the resulting distance difference exactly offsets the active rotation of the sprocket 54, making the sprocket 54 and the supporting plate 6 in a horizontal position. By setting the buffer part 213 as an irregular arc, the arc of the buffer part 213 can be manually changed according to the actual situation to control the transmission speeds of the outer ring chain 21 and the inner ring chain 31.

[0027] Refer to Figure 1 、 Figure 2 and Figure 4 Referring to

[0028] Specifically, in actual applications, the first power source 74 rotates directly to drive the transmission shaft 72 to rotate. The transmission shaft 72 drives the sprocket one 73 to rotate. The sprocket one 73 rotates to drive the outer ring chain 21 to rotate, and the outer ring chain 21 can drive the supporting plate 6 to move; the second power source 77 rotates to drive the gear platform and the sprocket two 76 to rotate. The sprocket two 76 can directly drive the inner ring chain 31 to rotate, and the inner ring chain 31 can assist the movement of the supporting plate 6, making the supporting plate 6 move in a horizontal state.

[0029] Refer to Figure 1 Referring to

[0030] Specifically, in actual applications, the transfer mechanism one 8 and the transfer mechanism two 9 can drive the stable movement of the egg trays.

[0031] Refer to Figure 4, one side of the supporting plate 6 in contact with the egg tray is provided with a notch 61, a rubber sleeve 62 is arranged on the notch 61, there are multiple pairs of supporting plates 6, and the distance between the same pair of supporting plates 6 is less than the width of the egg tray and greater than the width of the first conveying mechanism 8.

[0032] Specifically, in actual application, the friction between the supporting plate 6 and the egg tray can be increased through the setting of the rubber sleeve 62. Through the setting that the distance between the same pair of supporting plates 6 is less than the width of the egg tray and greater than the width of the first conveying mechanism 8, when the supporting plate 6 moves upward, it can contact the egg tray and avoid contacting the first conveying mechanism 8.

[0033] Embodiment two of the first transmission component 2, refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 , the first transmission component 2 is the outer ring 22, the second transmission component 3 is the inner ring gear 32, the balance component 5 is the gear 55, the power assembly 7 includes a first bearing 711 installed on the side wall of the housing 1, the outer ring 22 is installed on the inner ring of the first bearing 711, a second bearing 712 is installed on the inner ring of the outer ring 22, the inner ring gear 32 is installed on the inner ring of the second bearing 712, a first gear 713 is installed on the inner ring of the outer ring 22, and a second gear 714 is installed on the inner ring of the inner ring gear 32; A fixed bearing 715 is installed on the side wall of the housing 1, a rotating shaft 716 is installed on the inner ring of the fixed bearing 715, a third gear 717 meshing with the first gear 713 and a fourth gear 718 meshing with the second gear 714 are installed on the rotating shaft 716; a driving motor 719 is installed at the lower end of the housing 1, and the driving motor 719 is in transmission connection with the rotating shaft 716.

[0034] Specifically, in actual application, the gear 55 meshes with the inner ring gear 32. The outer ring 22 and the inner ring gear 32 are in the shape of regular circles. Through the action of the first bearing 711, the outer ring 22 can rotate stably. Through the action of the second bearing 712, the inner ring gear 32 can rotate stably. The inner ring gear 32 and the outer ring 22 are in a state of relative rotation; when the driving motor 719 rotates, it can drive the rotating shaft 716 to rotate, and the rotating shaft 716 drives the third gear 717 and the fourth gear 718 to rotate. By controlling the transmission ratios of the first gear 713 and the third gear 717 and the second gear 714 and the fourth gear 718, it can be realized that the first gear 713 and the second gear 714 rotate at the same rotational speed and drive the outer ring 22 and the inner ring gear 32 to rotate at the same linear speed.

[0035] Refer to Figure 5 , a third conveying mechanism 10 is installed on the housing 1. Every time a layer of egg trays is placed on the third conveying mechanism 10, the third conveying mechanism 10 moves horizontally to keep the multiple layers of egg trays stacked vertically.

[0036] Specifically, in actual applications, since the outer ring 22 and the inner ring gear 32 are regular circles, if the egg tray is placed on the third conveyor mechanism 10 and the third conveyor mechanism 10 does not move, as the egg trays are stacked, a tilted state will occur. Therefore, every time a layer of egg trays is placed on the third conveyor mechanism 10, the third conveyor mechanism 10 moves horizontally to keep the multiple layers of egg trays stacked vertically. Finally, the egg trays are moved to the next process through the conveyance of the third conveyor mechanism 10.
