It is usually used for packaging, making boxes, display boards, book covers, etc. Common types include corrugated cardboard, grey board and hardboard. During the cardboard production process, the formed cardboard needs to be cut so that the cardboard can meet the relevant size requirements;

[0003] For example, the patent with publication number CN210758092U specifically discloses a cutting device for cardboard production, which includes a main body, a collection box is arranged on the main body, and slideways are fixedly installed at both ends of the main body, and a slide plate is installed on the main body, and both ends of the slide plate are located inside the slideway;

[0004] During the implementation of the above patent, after the cutting device places the cardboard on the main body, due to the use and transportation in the middle, the cardboard will be mixed with dust and debris. At this time, the debris on the main body can be scraped by moving the slide plate on the slideway, and the scraper is moved to the collection box position, so that the debris can slide smoothly to the collection box, so that the dust and debris can be cleaned;

[0005] When the cutting device is used to cut paper, the paperboard needs to be cut into a specified length due to processing requirements. However, when the cutting device is used, the staff generally uses a tape measure or other tool to measure the length of the paper and then cuts it after the size is determined.

[0006] However, the above manual measurement method is prone to deviation, which will affect the cutting accuracy of the cardboard;

[0007] Therefore, it is necessary to provide a paperboard cutting device to solve the above problems.

[0008] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0009] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a cardboard cutting device, which solves the problem that the size of the cardboard needs to be manually determined during the cutting process.

DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1 - Figure 2 As shown, the present application provides a cardboard cutting device, comprising a cutting assembly 1, and an adjusting assembly 2 fixedly mounted at one end of the cutting assembly 1, wherein the cutting assembly 1 is used to cut the cardboard, and the adjusting assembly 2 is used to limit the position of the cardboard, so that the cardboard can be cut into a required size;

[0032] Meanwhile, the cutting assembly 1 comprises a support frame 11, on which a cylinder 12 is fixedly mounted, and a cutter 13 is fixedly mounted on the output shaft of the cylinder 12, and a bottom plate 18 is fixedly mounted near the cutter 13 at the bottom of the support frame 11, and a second groove 19 is formed on the bottom plate 18, and the cardboard passes through the bottom plate 18 and the cutter 13, so that the cutter 13 moves downward after the cylinder 12 is turned on, so that the cardboard placed on the bottom plate 18 can be cut, and the cutter 13 continues to move to the second groove 19, so that the cutter 13 can cut the cardboard;

[0033] Both ends of the cutter 13 are slidably mounted with positioning rods 14, and a pressing plate 16 is fixedly mounted at the bottom of the two groups of positioning rods 14. At the same time, a first groove 17 is provided on the pressing plate 16. The first groove 17 and the second groove 19 are in a flush position with each other and have the same size. At the same time, the bottom of the cutter 13 can pass through the inside of the two grooves respectively. The outer side of the positioning rod 14 is sleeved with a spring 15, so that when the paper is cut by the cutter 13, the bottom of the pressing plate 16 will first contact the cardboard on the bottom plate 18, so that the cardboard can be pressed tightly, thereby preventing the cardboard from shaking when being cut by the cutter 13. Then, the cutter 13 can continue to descend through the first groove 17, so that the pressed cardboard can be cut smoothly. Then, when the cutter 13 is reset by the cylinder 12, the spring 15 is between the cutter 13 and the pressing plate 16, so that the pressing plate 16 can rebound quickly.

[0034] Because the cardboard needs to be placed before cutting, and the size also needs to be limited, so:

[0035] like Figure 1 and Figure 3 As shown, the adjustment assembly 2 includes a storage box 21, on which a limiting plate 25 is provided, and the limiting plate 25 is used to block the end of the paperboard, so that the position of the paperboard can be limited when cutting;

[0036] At the same time, a fixing plate 27 is fixedly installed at one end of the storage box 21 close to the support frame 11, and a turning handle 28 is rotatably connected inside the fixing plate 27. At the same time, a second bevel gear 29 is fixedly installed at one end of the turning handle 28 passing through the fixing plate 27, and limiting grooves 23 are provided at both ends of the storage box 21. A threaded rod 24 is installed at the internal bearing of one of the limiting grooves 23. At the same time, a first bevel gear 26 is fixedly installed at the input end of the threaded rod 24, and the outer ring of the threaded rod 24 is threadedly connected to the bottom of the limiting plate 25, and the first bevel gear 26 and the second bevel gear 29 are meshed with each other, so that after the staff rotates the turning handle 28, the second bevel gear 29 rotates the first bevel gear 26, and then the threaded rod 24 rotates at the limiting groove 23, so that the position of the limiting plate 25 can be adjusted on the storage box 21, so that the cardboard can be in different positions through the limiting plate 25, and then the length of the cardboard to be cut can be adjusted;

[0037] A scale (not shown) is installed on the storage box 21 near the limit plate 25, so that the limit plate 25 can be compared with the scale when moving, so that the adjustment distance of the limit plate 25 can be accurately controlled;

[0038] like Figure 1 As shown, a guide groove 22 is provided on the storage box 21, and the guide groove 22 extends to one end of the storage box 21, and the guide groove 22 is inclined, and the height gradually decreases in the direction away from the bottom plate 18, so that after the cardboard is cut, the cardboard will fall into the guide groove 22, and then the cardboard will slide to the outside of the device through the inclined setting, and manual replacement can be avoided.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
