Description

Technical Field

[0001] This article belongs to the technical field of pushing materials for cartoning and packaging, and specifically relates to a connecting rod pushing mechanism for automatic cartoning and packaging. Background Art

[0002] Automation refers to the process by which machinery, equipment, systems, or processes (production and management processes) achieve desired goals through automated detection, information processing, analysis and judgment, and manipulation and control, with minimal or no direct human involvement, in accordance with human requirements. Automation technology is widely used in industry, agriculture, military affairs, scientific research, transportation, commerce, healthcare, services, and the home. The adoption of automation technology not only liberates people from heavy physical labor, some mental labor, and harsh and dangerous working environments, but also expands human organ functions, significantly improves labor productivity, and enhances humanity's ability to understand and transform the world.

[0003] Contact lenses are packaged in PP cups, each containing a contact lens protected by care solution. The PP cups are arranged in a horizontal snap-off arrangement, and the outer cardboard packaging for these PP cups is also in a strip format, facilitating layout, production, packaging, and logistics. Since contact lenses are medical supplies, regulations require that instructions be included inside each cardboard package. To accommodate these instructions, the strip packaging is folded into small pieces, placed on top of the lens, and then pushed into the box.

[0004] However, the usual pushing method will cause the folded instruction manual to bounce open, resulting in interference between the instruction manual and the packaging box during the pushing process, making it impossible for the instruction manual to smoothly enter the interior of the packaging box, thereby reducing the automated production efficiency. Utility Model Content

[0005] In order to solve the above problems, this paper proposes a connecting rod pushing mechanism for automatic box packaging, the connecting rod pushing mechanism is arranged on the outside of the conveyor belt of the automatic box packaging device, the outer end surface of the connecting rod pushing mechanism is aligned with the opening of the packaging box and the contact lens box, the connecting rod pushing mechanism includes a pushing block, a pressing block, a fixed slide rail, an eccentric wheel and a guide slider, the transverse center line of the fixed slide rail is collinear with the center line of the packaging box and the contact lens box, the front end outer side of the fixed slide rail is provided with a pushing block through the guide connection type, the rear end outer side of the fixed slide rail is provided with a guide slider through the guide connection type, the rear end of the fixed slide rail is provided with an eccentric wheel below, the rear end center of the pushing block is connected to the eccentric wheel through the main push rod, the pressing block is provided above the pushing block, and the pressing block is connected to the eccentric wheel through the passive pulling arm and the fixed The rocker arm is connected to the wire slider, one end of the fixed rocker arm is fixedly connected to the pressure block, and the other end of the fixed rocker arm is axially connected to the axially passive pull arm. The middle part of the front end of the passive pull arm is axially connected to the push block through a linkage pull rod, and both ends of the passive pull arm are axially connected to the fixed rocker arm and the front end of the guide slider, and both ends of the linkage pull rod are axially connected to the push block and the passive pull arm. The displacement of the pressure block is controlled by the push block and the guide slider, and the upward and downward arc movement control of the pressure block is achieved during the pushing process of the push block. In the process of pushing the contact lens box, the instruction manual can be pressed down and fixed by the pressure block to prevent the instruction manual from warping when placed in the packaging box and failing to smoothly enter the interior of the packaging box, thereby ensuring smooth and stable automated packaging.

[0006] The contact lens case is a semicircular PP sealed box with instructions on the top of the contact lens case. The instructions are multi-layer foldable and placed flat on the top of the contact lens case. Detailed instructions need to be placed inside the outer packaging of the contact lens case to meet the regulations. Therefore, the instructions need to be folded multiple times to meet the packing requirements of the small packaging box.

[0007] The fixed slide rails are fixed horizontal slide rails. The fixed slide rails are all equipped with guide-type sliding connections with the push block and the guide slider. The fixed slide rails and the packaging box, contact lens box, push block and guide slider are all aligned with each other, so that the multi-point one-line form can be used to achieve linkage type linear precision push-in.

[0008] The push block is in the shape of a rectangular block, the upper surface of the push block is flush with the upper surface of the instruction manual, the front end face of the push block is parallel to the end face of the contact lens box, and the rear end of the push block is provided with an axle ear, and the push block is axially connected to the main push rod and the linkage pull rod through the axle ear. The eccentric wheel is a rotating pull-push eccentric wheel, the center of the eccentric wheel is axially connected to the motor, and the outer surface of the eccentric wheel is axially connected to the main push rod. The rotation of the eccentric wheel simply and efficiently realizes the reciprocating motion of the push block, thereby realizing the sequential pushing of the contact lens boxes, and the linkage pull rod can simultaneously pull the passive pull arm during the movement of the push rod, thereby realizing the linkage control of the pressure block.

[0009] The pressure block is suspended above the push block, and the rear end of the pressure block is connected to the fixed rocker arm at a fixed angle at an angle above. The pressure block moves up and down through the passive pulling arm and the fixed rocker arm in an arc-shaped rocking manner. The guide slider is a small guide slider, and the front end of the guide slider is axially connected to the end of the passive pulling arm through the shaft ear. By setting the fixed rocker arm at an oblique position, the rear end of the pressure block is fixed to the passive pulling arm, so that the passive pulling arm can be lifted or lowered by the linked pull rod, and the pressure block can be moved up and down at an arc angle, and can also be kept parallel to the instruction manual when the pressure block presses down the instruction manual, thereby improving the stability of the guarantee.

[0010] Beneficial effects:

[0011] By controlling the displacement of the pressing block through the linkage of the pushing block and the guide slider, the pressing block can be controlled to move in the up and down arc direction during the pushing process of the pushing block. As a result, the instruction manual can be pressed down and fixed by the pressing block during the pushing process of the contact lens box, preventing the instruction manual from warping and being unable to enter the interior of the packaging box smoothly when placed in the packaging box, thereby ensuring smooth and stable automated packaging.

[0012] By fixing the slide rails and the packaging box, contact lens box, push block and guide slider, they are all aligned with each other, so that a multi-point one-line form can be formed to achieve linked linear precision pushing.

[0013] The rotation of the eccentric wheel simply and efficiently realizes the reciprocating motion of the push block, thereby realizing the sequential pushing of the contact lens boxes, and the linkage pull rod can simultaneously pull the passive pull arm during the movement of the push rod, thereby realizing the linkage control of the pressure block.

[0014] By setting a fixed rocker arm at an oblique angle at the rear end of the pressing block, the pressing block can be moved up and down at an arc angle when the passive pulling arm is lifted or lowered by the linked pulling rod, and can also remain parallel to the instruction manual when the pressing block presses down the instruction manual, thereby improving the stability of the guarantee.
