Description

Technical Field

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

[0002] The production of packaging cartons needs to be cut according to the size and shape of the cartons. When using a cardboard cutter for cutting paper, in order to ensure production capacity, multiple groups of paper are generally cut in batches. Batch cutting requires that the paper piles are stacked neatly. Since it is strictly forbidden to touch the paper with hands during cutting, the cutting depends entirely on the downward pressure of the cutter to cut the paper synchronously. Due to the different materials of paper, it is often offset and misaligned when cut after stacking, resulting in uneven or even skewed tangents, resulting in a decrease in product accuracy.

[0003] After searching, the Chinese patent application number CN202221978431.1 discloses a fully automatic paper cutter for cardboard processing, including a base, a feeding device body and a screw sleeve. The feeding device body is fixed to one end of the outer top surface of the base, and a guide groove is provided on one side of the feeding device body. However, since the above technical solution does not provide a corresponding mechanism that can stably squeeze and limit the cardboard being cut, there is still a problem that the cutting part of the cardboard is prone to shaking when the cardboard is cut by the cutter, resulting in low paper cutting accuracy.

[0023] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example 1

[0025] A paper cutter, such as Figure 1-4 As shown, it includes a mounting platform 1, the outer wall of which is fixed with a support frame 5, the outer wall of which is slidably connected with a slider 11, the outer wall of which is fixed with a movable rod 10, the outer wall of which is fixed with a mounting sleeve 8, the inner wall of which is slidably connected with a cutting machine 9, the output end of which is provided with a cutting disk 21, the outer walls of both sides of the cutting machine 9 are respectively fixed with connecting blocks 19, the outer walls of both sides of the mounting sleeve 8 are respectively provided with guide grooves 20, the connecting blocks 19 are slidably connected to the inner walls of the guide grooves 20, the outer wall of one side of the connecting block 19 is fixed with an elastic telescopic rod 18, the elastic telescopic rod 18 penetrates the outer wall of one side of the movable rod 10, and the telescopic end of the elastic telescopic rod 18 is fixed with a pressing plate 17; a group of supporting plates 4 are fixed to the outer wall of the top of the mounting platform 1, and a clamping mechanism is provided on the outer wall of the supporting plate 4.

[0026] The staff first places the cardboard to be cut on the support plate 4, and then controls the clamping mechanism on the support plate 4 to clamp and fix the two sides of the cardboard. Then the staff turns on the cutter 9 and presses the cutter 9 downward to allow the cutting disc 21 at the bottom of the cutter 9 to move downward to a height consistent with the gap between the two support plates 4. Then the staff pulls the cutter 9 as a whole to move forward under the guidance of the mounting sleeve 8 and the slider 11, so that the rotating cutting disc 21 cuts the cardboard placed on the support plate 4. At the same time, the elastic telescopic rods 18 on both sides of the mounting sleeve 8 will also move downward with the cutter 9, so that the pressure plate 17 set at the bottom of the elastic telescopic rod 18 can be against the cardboard being cut, thereby improving the stability of the cut part of the cardboard.

[0027] like Figure 1 As shown, the clamping mechanism includes an internal thread block 6, a threaded rod 12 and a push plate 7. The internal thread block 6 is fixed on the outer wall of the support plate 4. The threaded rod 12 is connected to the inner wall of the internal thread block 6 by threads. The push plate 7 is rotatably connected to the outer wall of one side of the threaded rod 12, and the push plate 7 is slidably connected to the outer wall of the support plate 4. After the staff places the paper to be cut on the support plate 4, the threaded rod 12 can be rotated to push the push plate 7 forward, thereby clamping the paper to be cut, and cooperating with the pressure plate 17 to clamp and fix the paper during cutting, thereby improving the stability of the paper when being cut.

Then the staff turns on the cutter 9 and presses the cutter 9 downward to allow the cutting disc 21 at the bottom of the cutter 9 to move downward to a height consistent with the gap between the two support plates 4. Then the staff pulls the cutter 9 as a whole to move forward under the guidance of the mounting sleeve 8 and the slider 11, so that the rotating cutting disc 21 cuts the cardboard placed on the support plate 4. At the same time, the elastic telescopic rods 18 on both sides of the mounting sleeve 8 will also move downward with the cutter 9, so that the pressure plate 17 set at the bottom of the elastic telescopic rod 18 can be against the cardboard being cut.
