Description

Technical Field

[0001] The utility model relates to the technical field of printing processing, in particular to an automatic feeding device. Background Art

[0002] A plotter is a device used to write words or patterns on the surface of various materials. It is widely used in industrial manufacturing, advertising, art design and other fields. When using a plotter to write words and patterns on a printed sheet, the printed sheet needs to be placed on the loading port of the plotter, and then the conveying device on the plotter will transport the sheet to the inside for writing words and patterns.

[0003] Traditional single-page loading is manual loading, that is, manually taking the printed single page and placing it on the loading port of the engraving machine. For a small number of single pages, manual loading can be handled simply. However, if a large number of printed single pages are processed in batches, manual loading is not only time-consuming and labor-intensive, but also inefficient. Utility Model Content

[0004] The utility model aims to provide an automatic feeding device, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] An automatic loading device includes a base plate, an outer cover shell is fixed on the upper surface of the base plate, a first driving mechanism is provided on the inner top wall of the outer cover shell, a mounting arm is installed below the inner top wall of the outer cover shell through the first driving mechanism, the first driving mechanism is used to drive the mounting arm to swing up and down, a second driving mechanism is provided on the mounting arm, a mounting plate is installed below the mounting arm through the second driving mechanism, the second driving mechanism is used to drive the mounting plate to move forward and backward to realize loading and feeding, a loading rack is provided below the mounting plate, and a pair of suction cups are provided on the loading rack.

[0007] It can be seen that by driving the mounting arm to swing down so that the suction cup can hold the single page, and by driving the mounting plate forward, the single page can be aligned and sent to the loading port of the engraving machine, thereby realizing automatic loading of printed single pages, replacing traditional manual loading. The loading process is faster, saves manpower, and is more efficient. It is suitable for batch engraving of multiple single pages.

[0008] Furthermore, the loading rack consists of a horizontal frame and a triangular plate. The triangular plate is fixed on one end of the horizontal frame, and the other end of the horizontal frame is hingedly installed under the mounting plate. Two suction cups are installed on the triangular plate, and a spring is connected between the upper surface of the triangular plate and the lower surface of the mounting plate.

[0009] Since one end of the horizontal frame is hinged on the mounting plate, and the triangular plate is connected to the mounting plate by a spring, the horizontal frame and the triangular plate can swing around the hinge. When the suction cup contacts the single page, as the mounting arm continues to swing downward, the triangular plate is compressed to drive the horizontal frame to rotate around the hinge. At this time, the spring is compressed, so that the lower end of the suction cup can be parallel to the surface of the single page, providing the sealing effect required for negative pressure suction, thereby ensuring that the single page can be firmly sucked. When the mounting arm swings upward, the horizontal frame and the spring can be pushed to reset under the action of the spring elastic force, and the structural layout is reasonable.

[0010] Furthermore, the first driving mechanism includes a first U-shaped seat, a shaft rod and a first driving motor. The first U-shaped seat is fixed on the inner top wall of the outer cover shell, the shaft rod is rotatably mounted on the first U-shaped seat, one end of the mounting arm is fixedly sleeved on the shaft rod, the first driving motor is fixed on one side of the first U-shaped seat, and the output shaft of the first driving motor is fixedly connected to one end of the shaft rod.

[0011] The first driving motor drives the shaft rod to rotate, and the rotating shaft rod can drive the installation arm to rotate, thereby providing a stable drive for the installation arm to swing up and down.

[0012] Furthermore, the second driving mechanism includes a threaded rod, a second driving motor and a nut seat. A guide groove is provided at the bottom of the mounting arm. The threaded rod is rotatably installed in the guide groove. The second driving motor is fixed on the end of the mounting arm. The output shaft of the second driving motor is fixedly connected to one end of the threaded rod. The nut seat is limitedly slidably installed in the guide groove and is threadedly mounted on the threaded rod. The mounting plate is fixed to the bottom end of the nut seat.

[0013] The second driving motor works, and its conveying shaft drives the threaded rod to rotate. The rotating threaded rod can threadably drive the nut seat to slide in the guide groove, thereby providing stable drive for the translation of the installation plate.

[0014] Furthermore, a second U-shaped frame is fixed on the lower surface of the mounting plate, a rotating shaft is rotatably mounted on the second U-shaped frame, a connecting seat is fixedly sleeved on the rotating shaft, and the horizontal frame is fixed on the side of the connecting seat.

[0015] The horizontal frame is fixed to the rotating shaft through a connecting seat, and the rotating shaft is rotatably connected to the second U-shaped frame fixed to the bottom of the mounting plate, thereby realizing the hinge connection between the horizontal frame and the mounting plate, so that the mounting plate and the horizontal frame have the ability to rotate.

[0016] Furthermore, positioning plates are fixed on both sides of the upper surface of the substrate respectively, and the upper surface of the substrate is located between the two positioning plates to form a space for limiting the position of a single page.

[0017] By placing the stacked single pages on the base plate between the two positioning plates, and using the positioning plates to provide a positioning effect for the single pages, it is possible to prevent the lower single pages from shifting when the suction cup presses the upper single pages, thereby ensuring that all single pages can be accurately loaded onto the engraving machine.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0019] 1. The utility model drives the mounting arm to swing downward so that the suction cup holds the single page, and drives the mounting plate forward to align the single page and send it to the loading port of the engraving machine, thereby realizing automatic loading of printed single pages, replacing traditional manual loading. The loading process is faster, saves manpower, and is more efficient. It is suitable for batch engraving of multiple single pages. In addition, the suction cup suction method will not damage the surface of the single page, thereby improving the yield rate.

[0020] 2. The utility model places the stacked single pages on the base plate between two positioning plates, and uses the positioning plates to provide a positioning effect for the single pages, so as to prevent the lower single pages from shifting when the suction cup presses the upper single pages, thereby ensuring that all single pages can be accurately loaded onto the engraving machine.
