DETAILED DESCRIPTION

[0037] The present application will be further described in detail below in conjunction with the drawings and specific embodiments.​​

[0038] Example: Figures 1-18 As shown in this embodiment, an egg clamp feeding left and right displacement adjustment device and its working method are provided for an egg packaging line. The device includes an egg conveying production line 100 for conveying egg trays. Egg clamp supports 200 that can be synchronously raised and lowered are provided on both sides of the egg conveying production line. An egg clamp lateral displacement positioning rod assembly 300 is provided on the egg clamp support. Two outer sides of the egg clamp support are respectively provided with egg clamp lateral displacement driving rocker arms 101. The upper end of the egg clamp lateral displacement driving rocker arm is hinged to a driving rod sleeve 103 fitted onto the end of the egg clamp lateral displacement positioning rod assembly via a short linkage rod 102. A roller 104 is hinged to the lower end of the egg clamp lateral displacement driving rocker arm. The inner end of the driving rod sleeve is connected to a spring 304 located between two adjacent gripper rotating sleeves via a gripper rotating sleeve 304 on the egg clamp lateral displacement positioning rod assembly. 5. Elastic contact is provided to keep the roller in contact with the double-stage drive ramps A and B. When the roller moves up and down with the egg clamp bracket, it can cooperate with the upper swing body 105, which is fixed to both sides of the production line and has double-stage drive ramps A and B respectively. When the roller of the egg clamp lateral displacement drive rocker arm on one side cooperates with the double-stage drive ramp A, the roller of the egg clamp lateral displacement drive rocker arm on the other side cooperates with the double-stage drive ramp B. The lower part of the upper swing body 105 is hinged to the corresponding side of the egg product conveying production line. The egg product production line is provided with a lower swing arm 106 that drives the upper swing body to swing. When the lower swing arms on both sides swing back and forth synchronously, the rollers of the drive rocker arms on both sides can work on the drive ramps at different work positions. The egg clamp on the egg clamp lateral displacement positioning rod assembly is moved left and right relative to the positioning rod 301 through the drive rod sleeve.

[0039] The width of the aforementioned double-stage driving inclined plane A is greater than that of the double-stage driving inclined plane B, meaning that the double-stage driving inclined plane A is located outside the double-stage driving inclined plane B. Due to the different widths of the double-stage driving inclined plane A and the double-stage driving inclined plane B, the swing angles of the lateral displacement driving rocker arms of the egg clamps on both sides are different. The swing angle of the lateral displacement driving rocker arm of one side of the egg clamp will be greater, while the swing angle of the lateral displacement driving rocker arm of the egg clamp on the other side will be less, thereby controlling the spring compression between the egg clamp components of the egg clamp mechanism.

[0040] When the egg product conveying production line drives the special-shaped egg tray to move forward by one station, the B' arrangement egg tray groove moves to the lower side of the egg clamp mechanism, the lower swing arm on the left side drives the upper swing body on the left side to swing, and the double-step driving slope B of the upper swing body on the left side works with the rollers of the egg clamp transverse displacement driving rocker arm. The lower swing arm on the right side drives the upper swing body on the right side to swing, and the double-step driving slope A of the upper swing body on the right side works with the rollers of the egg clamp transverse displacement driving rocker arm. When the egg clamp assembly moves downward, the rollers of the egg clamp transverse displacement driving rocker arm on both sides descend synchronously and work on the driving slopes at different stations. Since the width of the double-step driving slope B is smaller than that of the double-step driving slope A, the upper part of the egg clamp transverse displacement driving rocker arm on the right side rotates relatively larger than the hinge point, and the driving rod sleeve on the right side moves relatively larger along the positioning rod, so that the whole egg clamp assembly moves to the left side. At this time, the egg clamp assembly is aligned and matched with the B' arrangement egg tray groove, and the egg product of the egg clamp assembly is placed in the B' arrangement egg tray groove.

[0041] When the egg product conveying production line drives the special-shaped egg tray to move forward by one station, the B' arrangement egg tray groove moves to the lower side of the egg clamp mechanism, the lower swing arm on the left side drives the upper swing body on the left side to swing, and the double-step driving slope B of the upper swing body on the left side works with the rollers of the egg clamp transverse displacement driving rocker arm. The lower swing arm on the right side drives the upper swing body on the right side to swing, and the double-step driving slope A of the upper swing body on the right side works with the rollers of the egg clamp transverse displacement driving rocker arm. When the egg clamp assembly moves downward, the rollers of the egg clamp transverse displacement driving rocker arm on both sides descend synchronously and work on the driving slopes at different stations. Since the width of the double-step driving slope B is smaller than that of the double-step driving slope A, the upper part of the egg clamp transverse displacement driving rocker arm on the right side rotates relatively larger than the hinge point, and the driving rod sleeve on the right side moves relatively larger along the positioning rod, so that the whole egg clamp assembly moves to the left side. At this time, the egg clamp assembly is aligned and matched with the B' arrangement egg tray groove, and the egg product of the egg clamp assembly is placed in the B' arrangement egg tray groove.

[0042] The A' arrangement egg tray groove and the B' arrangement egg tray groove of the special-shaped egg tray are sequentially and alternately advanced to place the egg products until the special-shaped egg tray is full of egg products.

[0043] It is worth noting that when the roller of one side of the egg clamp transverse displacement driving rocker arm is on the double-step driving slope A and the roller of the other side of the egg clamp transverse displacement driving rocker arm is on the double-step driving slope B, the displacement of the driving rod sleeve pushed by the egg clamp transverse displacement driving rocker arm with the roller on the double-step driving slope A is larger than that of the egg clamp transverse displacement driving rocker arm with the roller on the double-step driving slope B on the other side, so that the driving rod sleeve on one side compresses the egg clamp assembly a little more and the driving rod sleeve on the other side compresses the egg clamp assembly a little less. Under the action of the spring force, the adjacent egg clamp assemblies move and adjust to the corresponding positions.

[0044] When the egg clip transverse displacement drive rocker arm rises with the egg clip mechanism, each egg clip assembly is reset under the spring elastic force between the egg clip assemblies; when the egg clip transverse displacement drive rocker arm descends with the egg clip mechanism, the egg clip assemblies on both sides are pressed to shift inward, the compression amount of the spring on one side is large, and the compression amount of the spring on the other side is small, and when the displacement on both sides is completed, the side with the large spring compression amount will shift to the side with the small spring compression amount, and the springs between the egg clip assemblies will automatically adjust to be uniform.

[0045] In the initial state, the width of the egg clip mechanism is greater than the width of the egg holder, and when the egg clip mechanism moves downward, each egg clip assembly is squeezed, and the distance between adjacent egg clip assemblies is aligned and adapted to the egg product placing groove of the egg holder.

[0049] In the embodiment of the present application, the egg clip transverse displacement driving rocker arm 101 comprises two swing pressure rods 112 and an extension rod 113, the upper ends of the two swing pressure rods are connected with the drive rod sleeves on the two positioning rods through linkage short rods respectively, the lower ends of the two swing pressure rods are hinged with the egg clip support through a connecting shaft 111, the extension rod is arranged below one of the swing pressure rods, and the roller 104 is arranged on the extension rod.
