[0002] In the production process of carbonless copy paper, the slitting process plays a crucial role in product quality and production efficiency.

[0003] Traditional carbonless copy paper cutting devices mostly use a fixed blade shaft structure. The blades are rigidly connected to the shaft by bolts. When it is necessary to increase or decrease the number of blades, the entire shaft and related connecting parts (such as bearings, couplings, etc.) must be disassembled. A single adjustment takes as long as 30-60 minutes, which seriously affects the production schedule. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable carbonless copy paper cutting device to solve the problem of time-consuming and laborious operation of adding or removing blades in conventional cutting devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable carbonless copy paper cutting device, comprising a cylinder, a movable plate, a slide, and a transmission shaft with several main gears. The slide is provided with several cutting assemblies composed of a slide frame and a swing arm. One end of the swing arm is rotatably mounted with a blade and a secondary gear via a rotating shaft. The secondary gear meshes with the main gear for transmission. A roller is rotatably mounted on the top of the slide frame. The movable plate is provided with several sliding holes for accommodating the rollers. The end of the movable plate is fixedly connected to the output end of the cylinder, so that the cylinder drives the movable plate to move horizontally and adjusts the spacing of the several cutting assemblies in accordance with the sliding holes.

[0006] Preferably, the side wall of the carriage is provided with a pair of round holes, and the end of the swing arm away from the secondary gear is locked into one of the round holes by a bolt.

[0007] Preferably, the sliding holes of the movable plate are inclined.

[0008] Preferably, the slide table is provided with a pair of guide rods, and the side wall of the slide is provided with a pair of through holes for the guide rods to pass through.

[0009] Preferably, the corners of the carriage are rounded for a smooth transition.

[0010] Preferably, the main gear is keyed to the drive shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model consists of a cutting assembly made up of a slide table, a slide frame, a swing arm, and blades. When it is necessary to increase or decrease the number of blades during production, the operation can be completed simply by rotating the swing arm. The adjustment operation is flexible and convenient, enabling the equipment to better adapt to the cutting operation of carbonless copy paper of different specifications and production requirements. The setting of the moving plate and cylinder makes it easy to adjust the spacing of the cutting assembly according to the specifications of the copy paper. The structure is simple, the operation is convenient, and the production efficiency of copy paper is effectively improved. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: an easily adjustable carbonless copy paper cutting device, including a cylinder 7, a moving plate 6, a slide 3, and a transmission shaft 1 with several main gears 2. The main gears 2 are keyed to the transmission shaft 1. In this application, a motor (existing technology, not shown in the figure) is connected to the end of the transmission shaft. The slide 3 is provided with several cutting blade assemblies composed of slide frames 4 and swing arms 9. The slide 3 is provided with a pair of guide rods. The side wall of the slide frame 4 is provided with a pair of through holes for the guide rods to pass through, which facilitates the adjustment of the position of the slide frame 4 on the slide 3. The slide frame 4 is an integrally formed U-shaped structure. The corners of the slide frame 4 are all rounded to smoothly transition, which has the advantage of avoiding sharp corners from scratching the skin. The swing arm 9 is rotatably installed at the center of the slide frame 4. The side wall of the slide frame 4 is provided with a pair of round holes. The end of the swing arm 9 away from the auxiliary gear 10 is locked in one of the round holes by bolts. One end of the swing arm 9 is rotatably mounted with a blade 5 and the auxiliary gear 10 via a rotating shaft. The number of blades 5 can be increased or decreased as needed by the setting of a pair of round holes. For example, when the number of blades 5 needs to be reduced, the bolts are removed and the swing arm 9 is rotated until the blades 5 rise, so that the end of the swing arm 9 away from the blades 5 is installed in the low round hole of the slide 4. The auxiliary gear 10 meshes with the main gear 2 for transmission. The advantage of this setting is that when the transmission shaft 1 drives the main gear 2 to rotate, the blades 5 are rotated and cut through the meshing of the auxiliary gear 10 and the main gear 2. The top of the slide 4 is rotatably fitted with a roller 8. The moving plate 6 is provided with several sliding holes to accommodate the rollers 8. The sliding holes of the moving plate 6 are set at an inclination. The end of the moving plate 6 is fixedly connected to the output end of the cylinder 7 so that the cylinder 7 drives the moving plate 6 to move horizontally and adjust the spacing of several cutting components with the sliding holes. When it is necessary to adjust the spacing of the cutting components according to the specifications of the carbon paper, because the sliding hole is set at an inclination, the spacing of the blades 5 can be adjusted by controlling the cylinder 7 to drive the moving plate 6 to move horizontally.

[0020] When the number of blades 5 needs to be reduced during production, the operation can be completed simply by rotating the swing arm 9. Compared to existing technologies, there is no need to disassemble the blade shaft, which greatly saves adjustment time. In the past, disassembling the blade shaft may have required a long time for complex operations such as bolt removal and shaft extraction. Now, by simply rotating the swing arm 9, the number of blades 5 can be adjusted in a short time, allowing the equipment to quickly adapt to different production needs and significantly improving production efficiency.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
