Description

Technical Field

[0001] The invention belongs to the technical field of printer cutters, and in particular relates to an anti-sticking printer cutter mechanism. Background Art

[0002] A printer is a common office equipment that can print electronic documents or images on paper and other media. Choose the right paper, such as ordinary printing paper, photo paper, card paper, etc., according to the type and purpose of the printer. Avoid using too thin or too thick paper to avoid affecting the print quality or damaging the printer. Printers play an important role in modern office and life. Choose a printer that suits your needs and use and maintain it correctly to improve work efficiency and print quality.

[0003] When a common printer cuts paper, due to the different sizes of different papers, smaller papers may rotate when moving in the printer, resulting in uneven cut paper, which leads to waste of materials. In addition, when the printer finishes cutting the paper, the cut paper is easy to stick to the cutter, which will affect the next use of the printer. In view of this, we propose an anti-sticking printer cutter mechanism. Summary of the invention

[0004] The object of the present invention is to provide an anti-sticking printer cutter mechanism to solve the problems raised in the above background technology.

[0005] In view of this, the present invention provides an anti-sticking printer cutter mechanism, comprising: A protective shell, wherein a mounting groove is provided in the protective shell, a paper cutting groove is provided in the protective shell and located on one side of the mounting groove, and a fixed knife is provided in the mounting groove and located at the bottom of the paper cutting groove; A fixing assembly, which is located in the protective shell and is used to fix the fixed knife; Two sliding grooves, both of which are provided on the inner wall of the mounting groove, and both of which are located above the paper cutting groove, a same cutting knife is slidably installed between the two sliding grooves, and the cutting knife is located on one side of the fixed knife, an electric push rod is fixedly installed at the bottom of the sliding groove, the output end of the electric push rod is fixed to the cutting knife, a rectangular block is fixedly installed on one side of the cutting knife, a rectangular groove is provided in the rectangular block, a lower pressure plate is slidably installed in the rectangular groove, the bottom of the lower pressure plate passes through the bottom of the rectangular groove and is fixedly installed with a rubber pad, a plurality of springs fixed to the top of the rectangular groove are fixedly installed on the top of the lower pressure plate, and a baffle is fixedly installed in the mounting groove and on the other side of the cutting knife; The limiting component is located in the paper cutting slot and is used to limit the position of the paper.

[0006] The two electric push rods will drive the cutting knife to move downward between the two sliding grooves, and the downward movement of the cutting knife will drive the rectangular block to move downward. The downward movement of the rectangular block will drive the lower pressure plate to move downward through a number of springs until the rubber pad at the bottom of the lower pressure plate is against the top of the paper, and then the cutting knife continues to move downward. At this time, the lower pressure plate will squeeze the springs to contract, and then the paper can be cut under the action of the fixed knife and the cutting knife. Ensure that when cutting the paper, the lower pressure plate and the rubber pad can first fix the paper to ensure that the paper will not deviate when cutting, and ensure that the cut paper can be more standard. After the cutting is completed, the two electric push rods will drive the cutting knife to move upward. At this time, the baffle can block the cut paper to ensure that the paper will not stick to the cutting knife and will not affect the next cutting work. When the fixed knife becomes blunt after long-term use, the personnel can release the limit of the fixed knife through the fixing component. At this time, the personnel can remove the fixed knife from the two limit blocks and replace it, and then fix the fixed knife through the fixing component to ensure that it is easy for personnel to replace the fixed knife and ensure that the fixed knife can continue to remain sharp.

[0007] In the above technical solution, further, the fixing assembly includes: Two limiting holes, both of which are provided on the fixed knife, a clamping groove is provided on the fixed knife and located between the two limiting holes, limiting blocks are fixedly installed on the inner wall of the installation groove and are respectively located in the two limiting holes, a rotating groove is provided in the protective shell and located on one side of the clamping groove, a rotating rod is rotatably installed in the rotating groove, a clamping disk is fixedly installed at one end of the rotating rod and located in the clamping groove, and a torsion spring is sleeved on the rotating rod and located in the rotating groove.

[0008] The clamping disc can fix the fixed knife, and at the same time, under the limiting action of the two limit blocks, the stability of the fixed knife can be guaranteed, ensuring that the fixed knife can be easily replaced and the fixed knife can be kept sharp continuously.

[0009] In the above technical solution, further, the limit block is plug-fitted with the limit hole, the clamping plate is clamp-fitted with the clamping groove, and the two ends of the torsion spring are tightly welded to the clamping plate and the inner wall of the rotating groove respectively.

[0010] In this technical solution, it is ensured that the limit block can be inserted into the limit hole, that the clamping plate can be clamped into the clamping groove, and that the structure of the torsion spring is stable.

[0012] In the present technical solution, when in use, personnel can first cut the paper width according to needs and turn the knob. The rotation of the knob will drive the threaded rod to rotate. Under the action of the thread, the rotation of the threaded rod will drive the limit plate to move. At the same time, personnel can observe the scale line until the limit plate moves to the appropriate position, and stop turning the knob. At this time, the distance between the limit plate and one side of the inner wall of the paper cutting groove is equal to the width of the paper, ensuring that the paper will not rotate when moving in the paper cutting groove.

[0013] In the above technical solution, further, the limiting plate is threadedly connected to the threaded rod, and one end of the threaded rod is rotatably connected to the protective shell.

[0014] In this technical solution, it is ensured that the rotation of the threaded rod can drive the limit plate to move, and that one end of the threaded rod can rotate normally in the protective shell.

[0015] In the above technical solution, further, the cross section of the slide groove is a T-shaped structure.

[0016] In this technical solution, it is ensured that the limit plate will not fall off from the slide groove.

[0017] In the above technical solution, further, the top of the fixed knife and the bottom of the paper cutting groove are located on the same horizontal line, and the output end of the electric push rod is tightly welded to the cutting knife.

[0018] In this technical solution, the structure of the fixed knife is ensured to be stable, and the output end of the electric push rod is ensured to be able to drive the cutting knife to move up and down.

[0019] In the above technical solution, further, the rubber pad is located below the cutting knife, and the cross-section of the rectangular groove is a T-shaped structure.
