Description

Technical Field

[0001] The utility model relates to the field of protective devices, in particular to a paper cutting safety protective device. Background Art

[0002] The paper cutter is a traditional product used to handle the paper cutting needs in the later stage of printing. The operation of the paper cutter is relatively simple and the environmental requirements are not high. It can usually be operated in a general office with power supply. During use, the stacked paper is cut by moving the cutting knife downward.

[0003] In Chinese utility model patents, for example, the utility model of CN218018663U discloses a safety protection device for a paper cutter. A lifting mechanism drives a cutting member with a protective structure to move downward, so that the cutting blade moves toward the paper. The protective plates on both sides are used to protect both sides of the cutting blade, preventing the cutting blade from flying out after breaking and causing injury to the staff, thereby making the paper cutting work safer.

[0004] When used, the above technology can prevent the cutting blade from breaking and flying out, causing injury to the staff. In actual use, the user needs to place the stacked paper under the cutting blade. At this time, the user's hand will go deep under the cutting blade, which can easily cause scratches on the hand. At the same time, if the blade suddenly falls while the user is placing the paper, it will cause serious consequences and pose a great safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-3The paper cutting safety protection device includes a base 1, a paper cutting box 2 is fixedly installed on the top surface of the base 1, and a revolving door 3 is rotatably connected to the side of the paper cutting box 2. At the same time, one end of the revolving door 3 is fixed to the paper cutting box 2 by magnetic attraction, and a visual window 4 is fixedly installed on the revolving door 3 for observing the internal situation of the paper cutting box 2. A handle 5 is fixedly installed on the outside of the revolving door 3 for easy rotation of the revolving door 3. A protrusion 9 is fixedly installed on the revolving door 3. A cavity is provided on the side wall of the base 1, and a card shaft 10 is slidably connected in the cavity. A fixed seat 12 is fixedly installed on the outside of the card shaft 10, and a spring 11 is jointly installed between the fixed seat 12 and the side wall of the cavity. A cutting device 13 is slidably connected in the base 1, and a plurality of first electric telescopic rods 15 are fixedly installed on the top wall of the base 1, and the bottom end of each first electric telescopic rod 15 is fixedly connected to the top surface of the cutting device 13. A through slot 14 is provided on the cutting device 13, and the diameter of the through slot 14 is greater than that of the card shaft When the door 3 is closed, the cutting device 13 can be rotated to move, thereby pushing the card shaft 10 to be locked in the through groove 14, limiting the position of the cutting device 13. When the door 3 is not closed, the cutting device 13 cannot be started to fall, thereby providing protection for the staff to place paper. At the same time, when the door 3 is rotated 90 degrees, the moving distance of the card shaft 10 is the largest, and the spring 11 facilitates the reset of the card shaft 10. At the same time, when the door 3 is rotated, the card pin 6 is continuously pressed against the top surface of the base 1 under the action of gravity, and then falls into the card groove 7, fixing the door 3 and making it difficult to rotate.

[0024] The bottom wall of the base 1 is slidably connected with a slide 16, and the slide 16 is L-shaped, which is convenient for limiting the position of the paper. A plurality of second telescopic rods 20 are fixedly installed on the side wall of the base 1, and a pressure plate 21 is commonly installed on the other end of the plurality of second telescopic rods 20, and the bottom surface height of the pressure plate 21 is greater than the top surface height of the slide 16, and the paper placed on the slide 16 can be squeezed by the pressure plate 21 for easy cutting. The base 1 drives the slide 16 to slide through the driving mechanism, and the driving mechanism includes a motor 19, and the motor 19 is fixedly installed on the side of the base 1. The output shaft of the motor 19 passes through the base 1 and is connected to the threaded rod 18. A plurality of slide grooves are symmetrically provided on the bottom wall of the paper cutting box 2. A plurality of threaded sleeves 17 are fixedly installed on the bottom surface of the slide 16, and each threaded sleeve 17 is slidably connected in the slide groove, and each threaded sleeve 17 is threadedly connected to the threaded rod 18. It is worth noting that the slide groove is square in shape, thereby limiting the threaded sleeve 17, making it unable to rotate, and thus can only move linearly.

[0025] When the present invention is used, when it is necessary to cut paper, the revolving door 3 is first rotated by the handle 5 and rotated ninety degrees. During the rotation, the latch 6 continuously contacts the top surface of the base 1 and then falls into the latch groove 7 to limit and fix the revolving door 3. As the revolving door 3 rotates, the protrusion 9 squeezes the latch shaft 10, thereby driving the latch shaft 10 to slide in the cavity. At this time, the position of the cutting device 13 is fixed. When the revolving door 3 is rotated ninety degrees, one end of the latch shaft 10 is locked into the through groove 14 provided in the cutting device 13, limiting the cutting device 13. When the staff closes the revolving door 3, the cutting device 13 can be dropped, thereby enhancing the safety of the staff in placing paper.

[0026] When the placement is completed, the handle 8 can be pulled to raise the latch 6, and then the limit of the revolving door 3 can be cancelled, and then the revolving door 3 can be rotated, and the paper cutting box 2 and the revolving door 3 are fixed by magnetic attraction. Then the motor 19 can be started to drive the slide 16 to move. When it moves to the specified position of the cutting device 13, the second telescopic rod 20 is started to squeeze the paper through the pressure plate 21 to facilitate cutting by the cutting device 13. When the cutting is completed, the revolving door 3 is rotated again, and then the paper can be taken out.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
