Description

Technical Field

[0001] This utility model belongs to the technical field of packaging box conveying, and relates to a cross-plate material gripping mechanism. Background Technology

[0002] In the packaging industry, as consumers' demands for product packaging increase, the neatness of the items inside the packaging box has become one of the important indicators for measuring packaging quality. To achieve this goal, cross-shaped dividers are often installed inside the packaging box to divide the internal space into four independent small sections, thereby ensuring that items can be placed individually and in an orderly manner.

[0003] Currently, cross-shaped partitions are typically manufactured by assembling two corrugated cardboard sheets, one long and one short. On existing production lines, the mechanism for gripping the cross-shaped partitions often uses two independent gripping mechanisms, one for the long board and one for the short board. This gripping method is prone to interference problems in actual operation, resulting in poor gripping performance and impacting production efficiency and product quality.

[0004] Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a cross-shaped partition material gripping mechanism that can efficiently and accurately grip the cross-shaped partition and solve the interference problem.

[0006] The objective of this utility model is achieved through the following technical solution:

[0050] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example

[0051] See Figures 1-4 As shown, a cross-shaped partition material gripping mechanism specifically includes the following main components:

[0052] The horizontal moving assembly 1 includes a lead screw module distributed along the horizontal direction. The lead screw module includes a drive motor, a lead screw, and a nut that engages with the lead screw. A slider is fixedly connected to the nut, enabling the slider to move along the axial direction of the lead screw. The lead screw module is a complete set of components and is commercially available.

[0053] The vertical lifting component 2 is fixed on the slider of the horizontal moving component 1 and has a built-in platform 21 that can move up and down. The lifting of the platform 21 is controlled by the drive device, thereby adjusting the height position of the material gripping mechanism.

[0054] A rotary drive assembly 3 is provided below the platform 21, including a rotary table that can rotate around its own axis to realize the rotation function of the material gripping mechanism.

[0055] The material gripping assembly 4 is fixed on the rotating table. Its core component is a four-jaw cylinder 41, on which four relatively movable clamping plates 42 are mounted, forming a clamping space between them. Each clamping plate 42 is designed with a set of first clamping plates 421 and second clamping plates 422 distributed at 90 degrees, so that the four clamping plates 42 together form a cross-shaped clamping structure, which is adapted to the shape of the cross partition. In addition, a limiting assembly 5 is provided to limit the movement range of the clamping plates 42, ensuring the stability and accuracy of clamping.

[0056] In this embodiment, the vertical lifting assembly 2 uses a cylinder-driven method to achieve the up-and-down movement of the platform 21. Specifically, the electric cylinder base 22 is fixedly mounted on the slider, ensuring the stability and responsiveness of the vertical lifting assembly 2. A vertical electric cylinder 23 is provided on the electric cylinder base 22, and the axis of the vertical electric cylinder 23 is consistent with the movement direction of the platform 21. The platform 21 is located below the electric cylinder base 22 so that the piston rod of the vertical electric cylinder 23 can directly act on it. The end of the piston rod of the vertical electric cylinder 23 is fixedly connected to the platform 21 by fasteners, so that when the vertical electric cylinder 23 is working, the extension and retraction of the piston rod can drive the platform 21 to move up and down.

[0057] Furthermore, guide sleeves 24 are symmetrically arranged on both sides of the vertical electric cylinder 23 to provide stable guidance. Guide posts 25 are respectively arranged inside the guide sleeves 24, extending vertically. The guide posts 25 penetrate downwards through the electric cylinder seat 22 and are fixedly connected to the platform 21, thereby ensuring that the platform 21 maintains a stable trajectory when moving up and down under the drive of the vertical electric cylinder 23.

[0058] In this embodiment, the rotary drive assembly 3 uses a rotary cylinder 31 as a power source. The rotary cylinder 31 is fixedly connected to the rotary table 32 through its output shaft, which can drive the material gripping assembly 4 to rotate 90 degrees around a fixed axis to meet the usage requirements of adjusting the angle of the cross partition.

[0059] In this embodiment, the material gripping assembly 4 includes a cylinder support plate 43 fixed on the rotary table 32. The cylinder support plate 43 is provided with a four-jaw cylinder 41, and can be fixedly connected to a clamping plate 42 through its four cylinder rods, thereby realizing the simultaneous driving of the clamping plate 42 to perform opening and closing actions.

[0060] Preferably, the clamping plate 42 is designed with an opening 423, and a pair of detection sensors 44 are provided on the outer sides of two adjacent clamping plates. These sensors can emit sensing light, which passes through the opening 423 to detect and identify whether the clamping plate has successfully gripped the cross partition, ensuring the accuracy and reliability of the gripping. In this embodiment, the detection sensors 44 are fixed to the cylinder support plate 43 by a connecting plate.

[0061] The limiting component 5 in this embodiment consists of two parts: an adjusting bolt and a stop block. The adjusting bolt and the stop block are cleverly mounted on two diagonally distributed clamping plates, forming a stable limiting structure. Specifically, the adjusting bolt is fixed to the corresponding clamping plate via a threaded connection, allowing for easy position adjustment as needed. The stop block, in conjunction with the adjusting bolt, effectively limits the movement range of the clamping plates, ensuring clamping stability.

[0062] In this embodiment, to enhance the stability and flexibility of equipment operation, a cable chain 6 is specially provided on one side of the platform 21. One end of the cable chain 6 is firmly fixed to the platform 21 to ensure that it moves stably with the platform 21; the other end is fixed to the housing of the lead screw module, and its position remains unchanged.

[0063] This invention utilizes a dual-axis motion system comprised of a horizontal moving component and a vertical lifting component. This system can quickly and accurately adjust the position of the gripping component in space, achieving precise control with multiple degrees of freedom and improving operational flexibility and stability. The four-jaw cylinder-driven clamping plate adopts a cross-shaped symmetrical distribution structure. This design, combined with the rotary table's angle adjustment function, allows the clamping component to adapt to the clamping requirements of different sized partitions, effectively solving the problem of poor positioning compatibility in traditional clamps. Furthermore, the limiting component effectively controls the opening and closing range of the clamping plate through mechanical constraints, ensuring a uniform distribution of clamping force and effectively preventing product deformation or detachment during clamping.
