DETAILED DESCRIPTION

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0023] like Figure 1-Figure 4 As shown, a cardboard fixed-distance cutting device comprises a driving roller shaft 1, a distance roller shaft 2 and a plurality of conveying roller shafts 3 which are parallel to each other, a first transmission wheel 4 which is slidably mounted on the driving roller shaft 1 and rotates synchronously with the driving roller shaft 1, a first connecting frame 5 which is slidably mounted on the distance roller shaft 2, and a cutting slide mechanism which is arranged parallel to the driving roller shaft 1;

[0024] A second connecting frame 6 is hinged on the first transmission wheel 4, the first connecting frame 5 is connected to the second connecting frame 6, and the second connecting frame 6 is rotatably connected to the second transmission wheel 7 and a tool 8 which is coaxially arranged and rotates synchronously with the second transmission wheel 7, and the first transmission wheel 4 is linked with the second transmission wheel 7;

[0025] A gear 9 meshing with the spacing roller 2 is rotatably connected to the first connecting frame 5 , and a bolt 10 abutting against the outer periphery of the spacing roller 2 is threadedly connected to the first connecting frame 5 .

[0026] Specifically, in the above technical solution, the driving roller 1 and the conveying roller 3 are driven by a power system, such as a motor, a gasoline engine, etc., and the conveying rollers 3 are arranged opposite to each other and cooperate with each other for conveying cardboard. The first transmission wheel 4 rotates with the driving roller 1, and drives the tool 8 to rotate through the linkage between the first transmission wheel 4 and the second transmission wheel 7, and cooperates with the cutting slide mechanism to complete the cutting of the cardboard. And the adjustment of the position of the tool 8 only requires twisting the gear 9, and the tool 8 can be driven to move through the meshing relationship between the gear 9 on the first connecting frame 5 and the spacing roller 2. By tightening the bolt 10, the end of the bolt 10 is abutted against the spacing roller 2, and the position of the tool 8 can be fixed. The distance between the tool 8 and the tool 8 can be corrected by a tape measure or the like. The entire process of adjusting the spacing of the tool 8 does not require the participation of multiple people, and can be operated by a single person, which is convenient and fast.

[0027] Further, such as Figure 1 , Figure 2 As shown, the cutting slide mechanism includes a slide rail 11 arranged parallel to the driving roller shaft 1, and a slide seat 12 is slidably connected to the slide rail 11, and the cutting edge of the tool 8 can be embedded in the notch 1201 on the slide seat 12. When the tool 8 rotates, the cutting edge of the tool 8 and the notch 1201 on the slide seat 12 form a certain shear force, and cooperate with the conveying roller shaft 3 to cut the cardboard. At the same time, the slide seat 12 can also move together with the tool 8.

[0028] Further, to facilitate the driving gear 9, as Figure 3 As shown, the shaft end of the gear 9 extends to the outside of the first connecting frame 5 and is provided with a polygonal groove 901. The rotation of the gear 9 can be assisted by a common tool such as a wrench.

[0029] Further, such as Figure 1 , Figure 2 As shown, the cross section of the driving roller shaft 1 is a regular polygon, and the first transmission wheel 4 is provided with a polygonal shaft hole that matches the driving roller shaft 1. While ensuring that the first transmission wheel 4 can slide on the driving roller shaft 1, it can also prevent the first transmission wheel 4 from slipping, thereby ensuring the linkage relationship between the first transmission wheel 4 and the driving roller shaft 1.

[0030] Further, such as Figure 1 , Figure 3 As shown, the first transmission wheel 4 and the second transmission wheel 7 are driven by a synchronous toothed belt 13. There is no relative sliding between the synchronous toothed belt 13 and the first transmission wheel 4 and the second transmission wheel 7, and the transmission ratio is more stable.

[0031] Further, such as Figure 3 As shown, the first connecting frame 5 is hinged with the second connecting frame 6. The installation and debugging of the fixed-distance cutting device is convenient, that is, when the position of the driving roller 1 is inconvenient to move, only the position of the fixed-distance roller 2 is moved to control the up and down adjustment of the overall position of the cutter 8.

[0032] In this embodiment, the hinge between the first transmission wheel 4 and the second connecting frame 6, the rotational connection between the second transmission wheel 7 and the second connecting frame 6, and the hinge between the first connecting frame 5 and the second connecting frame 6 can all use bearings as connecting parts to achieve hinged and rotational connections through bearings.

[0033] Working principle: Use a wrench or other tool to loosen the bolt 10 on the first connecting frame 5, so that the first connecting frame 5, the second connecting frame 6 and other components can move along the axial direction of the spacing roller 2. Take one side or another tool 8 of the device as a reference, and then use a length measuring tool such as a tape measure to confirm the position where the tool 8 needs to be fixed. Then twist the gear 9 on the first connecting frame 5, and the entire structure including the tool 8 can be displaced as a whole. When it moves to a certain distance, tighten the bolt 10 so that one end of the bolt 10 abuts against the outer periphery of the spacing roller 2, so that the position of the tool 8 can be fixed, and the spacing adjustment of the tool 8 is completed.

[0034] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
