Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a blanking device for a printing paper cutter. Background Art

[0002] A paper cutter is a machine used to handle paper cutting needs in the later stages of printing. A traditional product, paper cutters have evolved from mechanical paper cutters to tape-controlled paper cutters, and further to cutting systems with microcomputer control, color display, full-image operation guidance, visual processing, and computer-assisted cutting, external programming, and editing of production data. These systems have shortened production preparation time, increased cutting accuracy, reduced labor intensity, and made operations safer. As the number of sheets that a paper cutter can cut at a time increases, a paper cutter unloading device is required to temporarily store the cut sheets. Once a certain amount of paper has been stored, it is transferred to the printing press for printing.

[0003] Patent No. CN218170662U in the prior art discloses a blanking device for a paper cutter. This structure uses an adjustment component to drive the collection frame to rise and fall, effectively adjusting the height difference between the collection frame and the paper cutter. By reducing the height difference between the collection frame and the paper cutter, the efficiency of paper unloading can be greatly improved, and the collection device is more convenient for workers. However, in actual use, the interior of the collection frame of the prior art is prone to dust accumulation. When the paper is collected by the collection frame, dust adheres to the paper, affecting the cleanliness of the paper and affecting subsequent printing. In view of this, the utility model proposes a blanking device for a printing paper cutter. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a blanking device for a printing paper cutter.

[0005] The utility model is realized through the following technical solutions:

[0006] A feeding device for a printing paper cutter comprises a base, a feeding frame is provided on the top of the base, two electric push rods are provided between the base and the feeding frame, the bottom ends of the two electric push rods are fixedly mounted on the top of the base, and the output ends of the two electric push rods are fixedly connected to the bottom of the feeding frame, a plurality of support rods are fixedly mounted on the surface of the base, and two guide blocks are fixedly mounted on the two outer walls of the feeding frame, and the guide blocks are slidably connected to the outside of the support rods.

[0007] It can be seen that in the above structure, the electric push rod drives the aggregate frame to adjust the height, which can adjust the aggregate frame to the appropriate height of the paper cutter, improve the unloading effect, and the guide block slides and guides on the outside of the support rod to improve the stability of the aggregate frame adjustment.

[0008] The outer wall of the movable plate is provided with a rubber scraper, and the two inner walls of the movable plate are provided with a mounting groove, and a screw rod is provided inside one of the mounting grooves, and a sliding rod is provided inside the other mounting groove, and a threaded block and a slider are respectively provided on the outside of the screw rod and the sliding rod, and a motor is provided at one end of the screw rod, and the motor is fixedly installed at one end of the aggregate frame, and the output end of the motor is fixedly connected to the screw rod inside one of the mounting grooves, the threaded block is installed on the outside of the screw rod and is threadedly connected to the screw rod, and the slider is slidably connected on the outside of the slide rod, and the threaded block and the slider are respectively fixed on the outer wall of the rubber scraper, and the rubber scraper is adapted to the structure of the movable plate, and the outer wall of the rubber scraper is attached to the inner wall of the aggregate frame.

[0009] In order to improve the smoothness of paper feeding and reduce the phenomenon of paper scratching, two support seats are fixedly provided at one end of the collecting frame, a connecting rod is fixedly provided between the two support seats, and a guide roller is provided for rotating outside the connecting rod.

[0010] The beneficial effects of the utility model are:

[0011] The utility model provides a dust scraping structure. A motor drives a screw rod inside one of the installation slots to rotate, so that the threaded block moves. The threaded block drives the rubber scraper on the outside of the movable plate to slide against the inner wall of the collecting frame, and the slider slides on the outside of the slide rod for guidance. The rubber scraper can scrape and take out the dust generated on the inner wall of the collecting frame, thereby improving the cleanliness of the paper after unloading and avoiding affecting the subsequent printing of the paper.

[0012] When the paper is unloaded, the rubber scraper drives the movable plate to move, which can push the paper inside the collection frame and push the stacked paper to the outlet of the collection frame, making it easier for operators to collect and transport the paper.

[0013] The electric push rod can drive the collecting frame to adjust up and down, so that the height of the collecting frame is consistent with that of the printing paper cutter, which facilitates the rapid entry of paper from the printing paper cutter into the interior of the collecting frame for receiving, thereby improving the unloading efficiency. In addition, during the process of adjusting the collecting frame up and down, the guide block will be driven to slide and guide on the outside of the corresponding support rod, thereby improving the stability of the collecting frame during the process of adjusting the material up and down.

[0014] By rotating the guide roller outside the connecting rod, the paper can be guided when the paper cutter falls, improving the smoothness of paper unloading, reducing the scratching of the paper by the surface of the collecting frame, and reducing the damage rate.
