[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By arranging components such as a screw rod, a connecting plate, a cutting knife, and a mounting plate, during the working process, by controlling the rotation of the screw rod component, the screw rod component drives the mounting plate at one end to move, and drives the adjacent mounting plate to move accordingly under the action of the connecting component, so as to realize the equidistant arrangement of multiple mounting plates. While the mounting plate moves, it drives the cutting knife to move accordingly, indirectly adjusting the position of the cutting knife, and controlling multiple cutting knives to work synchronously under the action of the lifting component, thereby improving the processing efficiency of the device.

[0015] 2. By arranging components such as a spring, a fixing rod, a limiting plate, a tension spring, and a fixing block, during the working process, through the mutual cooperation between the spring component, the fixing rod component and the limiting plate component, the position between the sliding plate and the mounting plate is restricted, indirectly fixing the position of the cutting knife. By driving the limiting plate to release the restriction on the sliding plate, and through the mutual cooperation between the tension spring component and the fixing block component, the sliding plate is driven to drive the cutting knife to rise, achieving the effect of changing the cutting distance and the number of cuts, and increasing the applicable range of the device.

Specific embodiments

[0022] The following will disclose multiple embodiments of the utility model in the form of diagrams. For the sake of clarity, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the utility model. That is to say, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagrams, some conventional structures and components will be shown in a simple schematic manner in the diagrams.

[0023] Please refer to Figure 1 、 Figure 2 As shown in the figures, the adjustable cardboard cutting equipment for carton production of the utility model includes a fixed frame 1. A plurality of mounting plates 2 are arranged inside the fixed frame 1. A lifting assembly is arranged between the two sides of the plurality of mounting plates 2 and the fixed frame 1. An equidistant assembly is arranged at the upper ends of the plurality of mounting plates 2. A driving assembly is arranged between the plurality of mounting plates 2. A fixing plate 3 is arranged below each mounting plate 2. A cutting knife 4 is installed on each fixing plate 3. A sliding plate 5 is installed on the fixing plate 3. A fixing assembly is arranged between the sliding plate 5 and the mounting plate 2.

[0024] In this embodiment, one end of the mounting plate 2 is controlled to move through the driving assembly. While the mounting plate 2 is moving, the adjacent mounting plate 2 is driven to move along through the equidistant assembly, so as to realize the equidistant adjustment between the mounting plates 2. While the mounting plate 2 is moving, the sliding plate 5 and the cutting knife 4 are driven to move along, so as to adjust the distance between the cutting knives 4, and the mounting plate 2 is controlled to move up and down through the lifting assembly. The mounting plate 2 drives the cutting knife 4 to move up and down, realizing the effect of multiple cutting knives 4 synchronously cutting the cardboard, and improving the cutting efficiency.

[0025] Combined with Figure 2 、 Figure 3As shown, the fixing component includes a limiting plate 6 which is slidably installed on the mounting plate 2. The limiting plate 6 is inserted into the sliding plate 5. A fixing rod 7 is installed on the side of the mounting plate 2 away from the sliding plate 5. The fixing rod 7 is slidably arranged with the limiting plate 6. A spring 8 is arranged between one end of the fixing rod 7 and the limiting plate 6. The spring 8 is sleeved on the fixing rod 7. By driving the limiting plate 6 to move, one end of the limiting plate 6 is separated from the sliding plate 5, thus releasing the restriction on the sliding plate 5. At this time, the sliding plate 5 can drive the cutting knife 4 to move. While the limiting plate 6 moves, the spring 8 is compressed, so that the spring 8 has a thrust on the limiting plate 6. And when the sliding plate 5 moves to the preset position, the spring 8 pushes the limiting plate 6 to move to fix the sliding plate 5 and the mounting plate 2 together.

[0026] As Figure 4 shown, a tension spring 9 is arranged on one side of the sliding plate 5. Both ends of the tension spring 9 are provided with fixing blocks 10, and the two fixing blocks 10 are respectively installed on the mounting plate 2 and the sliding plate 5. While releasing the restriction on the sliding plate 5, the tension spring 9 drives the sliding plate 5 to move upward, and the sliding plate 5 drives the cutting knife 4 to move accordingly, so that the cutting knife 4 stops working, achieving the effect of changing the cutting distance.

[0027] Looking back Figure 2 as shown, the equidistant component includes a plurality of connecting plates 11. The connecting plates 11 are arranged in two layers and are connected end to end. The middle parts of the connecting plates 11 are rotatably installed on the corresponding mounting plates 2. The lifting component includes lifting plates 13. There are two lifting plates 13 which are symmetrically arranged. A telescopic cylinder 15 is arranged between the upper ends of the lifting plates 13 and the fixing frame 1. The mounting plate 2 is slidably arranged with the lifting plate 13. By controlling the telescopic cylinder 15 to work, when the telescopic cylinder 15 extends, it drives the cutting knife 4 to move downward, and when the telescopic cylinder 15 contracts, it controls the cutting knife 4 to move upward.

[0028] In this embodiment, the driving component includes a screw rod 12. Both ends of the screw rod 12 are rotatably installed on the fixing frame 1. One end of the screw rod 12 is provided with a driving source. For the driving source, for example, a servo motor commonly found in the existing market. The specific structure and working principle are not described and limited in detail here. The mounting plate 2 at one end is rotatably connected to the screw rod 12, the mounting plate 2 at the other end is threadedly connected to the screw rod 12, and the middle mounting plate 2 is slidably connected to the screw rod 12. By driving the screw rod 12 to rotate through the servo motor, the screw rod 12 drives the mounting plate 2 at one end to move. The mounting plate 2 drives the connecting plate 11 to rotate, and the connecting plate 11 drives the adjacent mounting plate 2 to move accordingly, so as to realize the equidistant arrangement of the mounting plates 2.

[0029] Guide rods 14 are arranged on both sides of the screw rod 12. The guide rods 14 are installed on the lifting plates 13. The guide rods 14 are slidably arranged with the mounting plates 2. The mounting plates 2 slide on the guide rods 14 while moving. The guide rods 14 support the mounting plates 2 and at the same time limit the moving direction of the mounting plates 2.

[0030] The above are only embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
