Description

Technical Field

[0001] The invention relates to the technical field of cardboard cutting, in particular to a paper cutter with a rotatable multi-sided blade. Background Art

[0002] In the cardboard processing industry, paper cutters, as an important equipment, play an indispensable role. Paper cutters are mechanical devices that can cut cardboard according to predetermined sizes. Usually, due to the need to meet the needs of cutting cardboard of different sizes and shapes, the design of paper cutters becomes particularly important.

[0003] However, traditional paper cutters have some obvious design shortcomings. Specifically, when cutting honeycomb paper, traditional paper cutters often press the cutter down hydraulically to cut the honeycomb paper. However, honeycomb paper is 3D and has height. When cutting with a single-sided blade, the cutter may flatten or damage the honeycomb paper to be cut. Therefore, a paper cutter with a rotatable multi-sided blade is proposed. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a paper cutter with a rotatable multi-sided blade, which has the advantages of rotating cutting of honeycomb paper and preventing damage to the honeycomb fabric. It solves the problem that traditional paper cutters often press the cutter down by hydraulic means to cut the honeycomb paper, but honeycomb paper is 3D and has height. When cutting with a single-sided blade, the cutter may flatten or damage the honeycomb paper to be cut.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of rotary cutting honeycomb paper and preventing the honeycomb fabric from being damaged, the present invention provides the following technical solutions:

[0012] The second driving assembly is used to make the cutter that performs linear feeding motion perform rotational cutting motion along the honeycomb panel cutting path, thereby realizing the cutting of the honeycomb panel.

[0013] The preferred technical solution of the present invention is that the first driving assembly includes a motor, a linear guide rail and a first transmission assembly, and the motor drives the first transmission assembly and drives the bracket arranged on one side of the moving end of the first transmission assembly to move along the linear guide rail.

[0014] A preferred technical solution of the present invention is that the transmission structure of the first transmission assembly includes a conveyor belt drive, a chain drive or other different types of transmission modes.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a paper cutter with a rotatable multi-edge blade, which has the following beneficial effects:

[0021] The paper cutter with a rotatable multi-sided blade makes a cutter on a bracket to make a linear motion under the drive of a first driving component, and makes the cutter on the bracket to rotate under the drive of a second driving component. The first driving component and the second driving component cooperate with each other to jointly realize the displacement and rotation of the cutter to cut the honeycomb paper. At the same time, the cutter is provided with at least three edges for cutting the honeycomb paper.

[0034] See also Figure 1-2 A paper cutter with a rotatable multi-sided blade is used for cutting honeycomb paper, comprising a frame 1, a cutter 2, a bracket 3, a first drive assembly 4 and a second drive assembly 5. The frame 1 has side plates 11 formed on both sides, and the first drive assembly 4 is installed as an installation base; the cutter 2 is provided with at least three edges 21 for cutting honeycomb paper; the bracket 3 is provided with a second drive assembly 5 connected to the cutter 2 on one side; the first drive assembly 4 is used to drive the bracket 3 linearly along the two side plates 11, and the bracket 3 drives the cutter 2 on the second drive assembly 5 to perform a linear feed motion; the second drive assembly 5 is used to rotate the cutter 2, and the cutter 2 performing a linear feed motion performs a rotary cutting motion along the honeycomb board cutting path, thereby realizing the cutting of the honeycomb board.

[0035] It should be noted that, unlike the traditional paper cutter, the rotary cutter 2 is used to cut the cardboard. The polygonal cutter 2 has a certain downward pressure on the cardboard when rotating and cutting. Compared with the circular cutter 2, the cutting efficiency is faster.

[0036] In this embodiment, the first drive component 4 includes a motor 41, a linear guide 42 and a first transmission component 43. The motor 41 drives the first transmission component 43 and drives the bracket 3 arranged on one side of the moving end of the first transmission component 43 to move along the direction of the linear guide 42; it should be noted that the bracket 3 is driven by the motor 41 to move in a straight line, and the feed speed, feed direction and rotation speed of the cutter during cutting are related to the rotation speed and direction of the motor 41.

[0037] See also Figure 7 In this embodiment, the transmission structure of the first transmission assembly 43 includes a conveyor belt transmission, a chain transmission or other different transmission modes; it should be noted that, Figure 7 It is a specific structure of a conveyor belt transmission, including a driving shaft 431, a driven shaft 432 and a traction belt 433. The traction belt 433 is annular and the two sides are respectively sleeved on the driving shaft 431 and the driven shaft 432. The driving shaft 431 is fixedly connected to the output end of the motor 41. A bracket 3 that moves following the traction belt 433 is provided on one side of the traction belt 433. The traction belt 433 is driven by the motor 41 to pull the bracket 3 to move linearly, thereby realizing the linear feeding movement of the cutter 2.

[0038] See also Figure 3 In this embodiment, at least one group of upper and lower limit blocks 31 are provided on the bracket 3, which are used to slide with the upper and lower ends of the linear guide rail 42. It should be noted that the cooperation between the limit blocks 31 and the linear guide rail 42 should be kept sufficiently smooth, so that the energy loss is smaller in the process of the bracket 3 moving to drive the cutter 2 to cut; at least one clamping member 32 for fixing on the moving end of the first transmission component 43 is provided on the bracket 3. It should be noted that the clamping member 32 can be clamped and fixed on one side of the above-mentioned traction belt 433, and the bracket 3 is driven by the motor 41 to move linearly. The movement direction of the cutter 2 can be changed by the forward and reverse rotation of the motor 41. The specific clamping structure can be a clamping component structure fixed by rotating a screw, a spring clamping structure, and a snap-on clamping structure.

[0039] See also Figure 4-6 In this embodiment, the second drive assembly 5 includes a second transmission assembly 51 and a rack 52. The rack 52 is fixed between the two side plates 11 and meshes with the second transmission assembly 51 for transmission. The second transmission assembly 51 is fixedly connected to the cutter 2 and both move together with the bracket 3. It should be noted that when the bracket 3 moves linearly through the drive of the motor 41, the second transmission assembly 51 and the rack 52 mesh with each other for transmission, providing power for the rotation of the cutter 2. The cutter 2 also has a rotating cutting effect when moving, thereby realizing the rotating cutter 2 to cut the honeycomb panel.

[0040] In this embodiment, the second transmission assembly 51 drives the bracket 3 through the first drive assembly 4 to drive itself to perform linear motion, and the cutter 2 on the second transmission assembly 51 rotates through the cooperation with the rack 52 .

[0041] It should be noted that, through the relative movement of the second transmission component 51 and the rack 52, and when the two are meshed with each other, the second transmission component 51 can be used as follows: Figure 4The structure comprises a first rotating member 511 rotatably connected to the bottom of the bracket 3 and a second rotating member 512 connected to the cutter 2, the first rotating member 511 comprises a first gear 5111 and a second gear 5112, the second rotating member 512 comprises a third gear 5121, the upper end of the second gear 5112 is meshed with the lower end of the rack 52, and the lower end of the first gear 5111 is meshed with the upper end of the third gear 5121; the first gear 5111 and the second gear 5112 are both on the first rotating member 511, so the rotation speeds of the two are the same, the first rotating member 511 drives the second rotating member 512 through the mutual cooperation of the first gear 5111 and the third gear 5121, and the rotation of the second rotating member 512 can drive the rotation of the cutter 2, the pitch circle diameter of the first gear 5111 is larger than the pitch circle diameter of the second gear 5112, and the pitch circle diameter of the second gear 5112 is conducive to the labor-saving rotation of the cutter 2, further reducing the energy loss, and the cutter 2 is more stable when rotating and cutting.

[0042] It should be further explained that the pitch circle diameter of the first gear 5111 is larger than the pitch circle diameters of the second gear 5112 and the third gear 5121; the pitch circle diameter of a gear refers to the diameter of a circle formed by the trajectory of the node in the gear motion plane in a gear transmission with a fixed transmission ratio, and the diameter of this circle is called the pitch circle diameter.

[0043] It needs to be further explained that Figure 8 This is a simplified schematic diagram for simulating cutting and does not represent the actual rotational motion trajectory of the cutter 2. This figure is only an explanation for the fact that the cutter 2 has a certain downward force during rotational cutting. When the multiple cutting edges 21 of the polygonal cutter 2 rotate, cutting force is generated through contact with the workpiece. This cutting force is converted into downward force during the rotation process, which helps to stabilize the cutting process and improve cutting efficiency.

[0044] In summary: the paper cutter with a rotatable multi-sided blade, driven by the first driving component 4, makes the cutter 2 on the bracket 3 make a linear motion, and driven by the second driving component 5, makes the cutter 2 on the bracket 3 rotate, and the first driving component 4 and the second driving component 5 cooperate with each other to jointly realize the displacement and rotation of the cutter 2 to cut the honeycomb paper, and at the same time, the cutter 2 is provided with at least three edges 21 for cutting the honeycomb paper, and the cutter 2 is performing a rotary cutting motion and a linear feeding motion along the cutting path of the honeycomb board. Compared with the traditional downward pressure cutting, it will not flatten or damage the honeycomb board, and will not cause problems such as adhesion during cutting, and cutting is more convenient.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
