[0023] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] Combined with Figures 1-5 As shown, a fixing device for a corrugated paper cutting device includes:

[0026] The mounting base 1 is the bottom support structure of the entire device, which is rectangular as a whole, and four chutes 11 are arranged on the top surface. The four chutes 11 are arranged in a circular array.

[0027] The cutting table 2 is arranged at the center of the top surface of the mounting base 1. A rectangular platform surface is provided at the top thereof and is used to place cardboard.

[0028] The mounting plate 3 is arranged on the four sides of the cutting table 2 to expand the top surface area of the cutting table 2 so as to place cardboard of various specifications and sizes.

[0029] The adjusting assembly 4 is arranged inside the cutting table 2. By means of movably connecting with the bottom surface of the mounting plate 3, the mounting plate 3 can be turned upwards or downwards, so as to discharge the remaining materials after cutting to the outside of the cutting table 2.

[0030] The centering assembly 5 is arranged inside the mounting base 1 and is used to squeeze and fix the side wall of the cardboard on the cutting table 2, and can also achieve an automatic centering effect by squeezing simultaneously on the four sides.

[0031] Specifically; in this embodiment, the four end faces of the cutting table 2 are respectively movably connected with the end faces of the four mounting plates 3 by means of a hinged structure, so that the four mounting plates 3 can all be turned upwards to a horizontal state, and the four mounting plates 3 are all arranged in a trapezoidal structure of the same size. Therefore, the four mounting plates 3 and the top surface of the cutting table 2 located at the center can just form a larger working table surface.

[0032] The adjusting assembly 4 includes a movable cylinder 41 fixedly installed inside the cutting table 2. A connecting part 42 is installed at the end of the telescopic end of the movable cylinder 41. Four positioning grooves 21 are vertically arranged on the outer side wall of the cutting table 2. The four positioning grooves 21 are arranged in a circular array. A part of the outer side wall of the connecting part 42 protrudes outwards and extends to the outside of the cutting table 2 respectively, and the protruding part is slidably assembled with the positioning groove.

[0033] A hinge seat A43 is provided on the end face where the connecting part 42 extends to the outside of the cutting table 2. A hinge seat B31 is correspondingly provided on the bottom surface of the mounting plate 3. A support rod 44 is also provided between the two. The two ends of the support rod 44 are respectively connected with the hinge seat A43 and the hinge seat B31 through hinge joints.

[0034] Combined with the structure of the above-mentioned adjusting component 4, the movable cylinder 41 can, by stretching or contracting, cause the four support rods 44 to expand outward or converge toward the center synchronously, and further cause the 4 mounting plates 3 to flip simultaneously around their connection parts 42 with the cutting table 2. When flipped upward to the horizontal state, it can cooperate with the top surface of the cutting table 2 to support the cardboard. When flipped downward to the inclined state, it can cause the cardboard waste after cutting to be discharged along its inclined surface, eliminating the need for manual assistance in cleaning and greatly improving the efficiency of automated production.

[0035] The centering component 5 includes a fixed frame 51 arranged on the sliding groove 11. The fixed frame 51 is composed of a slider 511, an electric telescopic rod A512, an auxiliary support 513, and a positioning plate 514. The slider 511 is slidably installed inside the sliding groove 11 and serves as the bottom support. At the center of the top surface of the slider 511, the electric telescopic rod A512 is arranged vertically upward. At both ends of the electric telescopic rod A512, the auxiliary supports 513 are respectively arranged vertically. The auxiliary support 513 is composed of two mutually movably sleeved metal tubes. A marking scale for observing the telescopic distance is also provided on the surface of the thinner one. Then, the tops of the two auxiliary supports 513 and the electric telescopic rod A512 are all fixedly connected to the bottom surface of the positioning plate 514. Therefore, the electric telescopic rod A512 can adjust the height of the entire fixed frame 51 to match cardboard thicknesses of different specifications and expand its scope of application.

[0036] The centering component 5 further includes a driving disk 52 rotatably installed inside the mounting seat 1. The driving disk 52 is circular and has a spiral groove on its top surface. The bottom of the slider 511 extends downward along the side wall of the sliding groove 11 and is slidably inserted into the groove. Therefore, the driving disk 52 can force the slider 511 to move along the sliding groove 11 direction through the arc-shaped inner wall of its groove, thereby driving the four fixed frames 51 to converge toward the center or expand outward synchronously. An additional driving motor 53 for driving the driving disk 52 to rotate is arranged inside the mounting seat 1. The driving motor 53 is arranged below the driving disk 52, and its central axis is directly inserted into the center of the bottom surface of the driving disk 52.

[0037] During actual use, the sizes of cartons vary, and the lengths of their four sides are also different. Especially for some rectangular cartons that are long and strip-shaped after folding, most of them are rectangular structures when initially unfolded. The above-mentioned fixed frames 51 that move the four sides synchronously toward the center cannot meet the requirements for fixing such cardboard. Therefore, in this embodiment, an electric telescopic rod B54 is additionally provided on the top surface of the positioning plate 514.

[0038] The output end of the electric telescopic rod B54 extends horizontally towards the center of the cutting table 2, and finally a fixing plate 55 is provided on its end face. An elastic pad is provided on the side of the fixing plate 55 facing the cardboard. The elastic pad can adopt structures such as sponge or rubber pad to act as a buffer layer. Therefore, the 4 electric telescopic rods B54 can be preset according to the length-width ratio of the cardboard, so that the fixing plates 55 on the four electric telescopic rods B54 can reach the side wall of the cardboard at the same time, fit and squeeze it, quickly position and fix it.

[0039] Moreover, in order to avoid the cardboard being crushed due to excessive clamping force, a pressure sensor can be appropriately arranged between its elastic layer and the fixing plate 55. For example, various pressure sensors such as BPZ0606 pressure sensor, eesx077a pressure sensor of Omron, U5600 wireless pressure sensor, AXCX series, etc. can be used. Its purpose is to preset the pressure tolerance in advance, so as to form a protective measure to avoid the cardboard being squeezed from the side by the centering component due to measurement errors, resulting in the cardboard being broken and unable to be combined into a complete carton, effectively ensuring the stability of the operation of the entire cutting equipment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
