DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] like Figure 1-11 As shown, a mechanism for adjusting the spacing of egg clamps for feeding eggs from an egg packaging line is provided, comprising an egg clamp rack 1 that is lifted and slidably connected to an egg conveyor line 6, an egg clamp mechanism being movably connected within the egg clamp rack, the egg clamp mechanism comprising a plurality of egg clamp assemblies 2 arranged at intervals, adjacent egg clamp assemblies being movably connected, an adjusting mechanism 3 for adjusting the spacing of egg clamps being installed on the egg clamp rack, the spacing between the egg clamp assemblies being indirectly adjusted by the adjusting mechanism so that the spacing of the egg clamp assemblies can be coordinated with the spacing of the placement positions on different egg trays. The egg conveyor line is a prior art, so no further description will be given.

[0031] In this embodiment, the egg clamp assembly includes left-right symmetrically arranged clamping jaws 4, and a horizontal rotating rod 5 is installed in the egg clamp frame. The two clamping jaws of the same egg clamp assembly are rotatably connected to the horizontal rotating rod on the same side in a one-to-one manner. The clamping jaws include a clamping portion and a flat plate portion that are connected to each other, and the clamping portion is inclined downward. The clamping portions of the two clamping jaws of the same egg clamp assembly are arranged opposite to each other, and a clamping jaw rotating sleeve 7 is installed at the connection between the clamping portion and the flat plate portion. The clamping jaw rotating sleeve is sleeved on the horizontal rotating rod, that is, the clamping jaw rotating sleeve is sequentially sleeved on the horizontal rotating rod. The rotation of the flat plate portion drives the clamping jaw rotating sleeve to rotate, thereby realizing the opening or closing of the clamping portions of the two clamping jaws of the same egg clamp assembly.

[0032] In this embodiment, the two adjacent clamping jaw rotating sleeves on the same side are connected by a spring 8, and the spring sleeve is provided on the horizontal rotating rod, that is, the clamping jaws on the same horizontal rotating rod are connected by a spring, and the distance between the clamping jaws on the same horizontal rotating rod is shortened or increased by squeezing or relaxing the outermost clamping jaw rotating sleeves at both ends of the same horizontal rotating rod.

[0033] In this embodiment, the adjusting mechanism includes a swinging pressure rod 9 located at both ends of the horizontal rotating rod, that is, a swinging pressure rod is provided at both ends of the two horizontal rotating rods, and one end of the two swinging pressure rods on the same side ends of the two horizontal rotating rods is coaxially connected to the egg clamp frame, that is, the two swinging pressure rods on the same side ends rotate synchronously. As long as one of them rotates, the other rotates synchronously. The axial direction of the rotating shaft of the swinging pressure rod is horizontally perpendicular to the axial direction of the horizontal rotating rod, that is, the moving surface of the swinging pressure rod is the vertical plane where the axis of the horizontal rotating rod is located. A compression sleeve 10 is hinged on one end of the swinging pressure rod, and the compression sleeve is slidably connected to the end of the horizontal rotating rod. The end of the compression sleeve abuts against the end of the outermost clamping claw rotating sleeve. Furthermore, the upper end of the swinging pressure rod is hinged with a linkage rod 11, and the other end of the linkage rod is hinged on the outer wall of the compression sleeve. The linkage rod is driven to move by the swinging pressure rod, thereby driving the compression sleeve to slide.

[0034] In this embodiment, the adjustment mechanism also includes an adjustment drive mechanism for driving the swing pressure rod to swing, and the adjustment drive mechanism includes a fan-shaped swing disk 12 located at both ends of the same horizontal rotating rod, that is, of the two swing pressure rods on the same side end of the two horizontal rotating rods, only one swing pressure rod needs to cooperate with the fan-shaped swing disk to achieve deflection, and the other swing pressure rod will rotate synchronously. The fan-shaped swing disk is rotatably connected to the egg conveyor line. Since the two fan-shaped swing disks are located at both ends of the same horizontal rotating rod, the two fan-shaped swing disks can be coaxially connected to both sides of the egg conveyor line, which is convenient for synchronous control of rotation. There are several stepped surfaces 13 of different heights distributed along the arc on the fan-shaped swing disk, and the rotation of the swing pressure rods at both ends of the horizontal rotating rod is convenient for synchronous control of rotation. The moving end extends downward to form an extension rod 14, and the end of the extension rod is rotatably connected to a roller 15 that slides with the step surface, that is, the connection between the extension rod and the swing pressure rod is rotatably connected to the egg clamp frame. Since the compression sleeve slides outward under the action of the spring elastic force, it will drive the end of the swing pressure rod to move outward, so that the end of the extension rod will abut against the step surface in real time. At the same time, due to the different heights of the step surfaces, the deflection angles of the extension rod are different, and the deflection angles of the swing pressure rod are correspondingly different, so that the compression sleeve controls the compression amount of the spring. When in use, the roller is controlled to slide with different step surfaces by rotating the fan-shaped swing turntable to control the compression amount of the spring, thereby controlling the spacing of the egg clamp components.

[0035] In this embodiment, for the sake of reasonable design, a driving rocker arm 16 is connected to the side of the fan-shaped swing turntable away from the outer circumference of the maximum arc, and the two driving rockers are coaxially connected to the two sides of the egg conveyor line, that is, the common rotating shaft of the two driving rockers is rotatably connected to the equipment frame of the egg conveyor line. A connecting rod mechanism for driving one of the driving rockers to rotate is installed on one side of the egg conveyor line. The one driving rocker arm is driven to rotate by the connecting rod mechanism, and then the two driving rockers rotate synchronously, thereby realizing synchronous switching between the rollers on both sides and different step surfaces.

When the handle needs to be rotated, first slide the handle until the tooth portion disengages the fixed latch, and then rotate the handle to achieve drive. When the handle needs to be fixed, slide the handle until the tooth portion is engaged in the fixed latch to achieve fixation of the handle.

[0037] In this embodiment, the egg clamp frame includes support plates 26 located on both sides of the egg conveyor line, that is, the horizontal rotation rod is installed between the upper parts of the two support plates, and the two support plates are connected by two left and right support connecting rods 27.

The opening and closing drive mechanism is installed between one end of the two synchronous drive rods. The two synchronous drive rods are located at one end of the opening and closing drive mechanism and are both equipped with a swinging assembly that drives the synchronous drive rod to rotate around the horizontal rotation rod. The opening and closing drive mechanism drives the swinging assembly to move; the swinging assembly includes a driving rotating sleeve 31, and a first connecting rod 32 and a second connecting rod 33 are connected to the outer periphery of the driving rotating sleeve. A mounting sleeve 34 is provided on the other end of the first connecting rod. The driving rotating sleeve is arranged on the horizontal rotation The mounting sleeve is fixed on the corresponding synchronous drive rod. When in use, the movement of the second connecting rod drives the driving rotating sleeve to rotate, and then drives the mounting sleeve to rotate around the horizontal rotating rod, so that the synchronous drive rod rotates around the horizontal rotating rod, and then drives the movement of the clamping claw flat plate to realize the opening and closing of the clamping claw assembly; the opening and closing drive mechanism includes an opening and closing drive motor 35, which is installed on one side of the egg clamp frame, that is, the opening and closing drive motor is installed between one end of the two synchronous drive rods, and the opening and closing drive motor is installed on the rotating shaft There is a turntable 36 that rotates synchronously with the rotating shaft, and a slider 37 or a pulley is installed on the end of the second connecting rod.
