Detailed implementation manners
[0025] To make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention to be protected, but merely represents the selected embodiments of the present invention.
[0026] Embodiment
[0027] Combined with Figures 1 to 5 , this embodiment provides a cutting device for a slitting rewinder, including a frame 1, and a conveying unit 2 and a cutting unit 3 configured on the frame 1.
[0028] Among them, the conveying unit 2 is used to input paper into the cutting unit 3. The cutting unit 3 includes a roller 4 and a tool holder 5 that are oppositely arranged on both sides to form a paper cutting channel. A plurality of cutting grooves 6 are arranged at intervals on the roller 4, and a plurality of cutters 7 corresponding to the cutting grooves 6 are provided on the tool holder 5 to cut out smaller-width paper along the length direction of the paper.
[0029] In particular, the tool holder 5 is provided with a guide rail 8 and a plurality of sliding seats 9 configured on the guide rail. Each sliding seat is configured with its own cutter 7, and the positions of the sliding seats 9 can be relatively independently adjusted to cut out paper with the required width size after moving to the designated position.
[0030] The cutting device of the slitting rewinder described above, through the cooperation of the cutting groove 6 provided on the roller 4 and the cutter 7 on the cutter holder 5, enables the paper to be accurately cut into smaller-width paper during the conveying process, ensuring the accuracy of the cutting size.
[0031] The guide rail 8 and the sliding seat 9 on the cutter holder 5 are designed to allow independent adjustment of the position of the cutter. Users can adjust the spacing of each cutter according to needs, so as to flexibly cut paper of different widths, meet the diverse production requirements, and the cutting unit 3 realizes continuous cutting operation through the combination of the roller 4 and the cutter holder 5, greatly improving the production efficiency and being suitable for large-volume paper slitting processing.
[0032] The structure of this cutting device is relatively simple. By reasonably and compactly arranging each functional unit, the maintenance difficulty of the equipment is reduced, and at the same time, the manufacturing cost is also reduced. The precise cutting and flexible width adjustment functions can reduce material waste, improve the utilization rate of steel, and have significant economic benefits.
[0033] It can be understood that the paper is not limited to materials such as paper, plastic, and steel.
[0034] Such as Figure 3 and Figure 4 As shown, in this embodiment, a guide block 10 is provided on the sliding seat. The cutter 7 includes a main body portion 11 clamped and fixed on the guide block 10, a direct push portion 12 provided on the main body portion 11, and a cutter portion 13 configured on the direct push portion 12, and the direct push portion 12 can drive the cutter portion 13 to approach or move away from the cutting groove 6. On the one hand, the guide block 10 on the sliding seat ensures that the main body portion 11 can be stably and accurately limited at the required cutting position. On the other hand, the direct push portion 12 of the cutter enables the cutter portion 13 to be flexibly adjusted to control its approach or movement away from the cutting groove 6, thereby realizing precise control of the cutting depth, being able to adapt to the cutting requirements of different thickness papers, and increasing the applicable range of the equipment. Preferably, the direct push portion 12 is driven by a cylinder or an electric cylinder.
[0035] Furthermore, the guide block 10 extends along the length direction of the guide rail, so that the main body portion 11 can adjust its position relative to the guide member in the same direction as the sliding seat. Thus, the main body portion 11 can independently adjust its position relative to the guide member, further increasing the flexibility of operation, and can make fine adjustments to the cutter position according to needs, ensuring that each cutter cuts at the best position and improving the cutting effect.
[0036] Preferably, the slides are arranged at intervals along the length direction of the guide rail, and at least six slides are provided. The number of the cutting grooves 6 and the cutters is equal to that of the slides. The slides are arranged at intervals along the guide rail to ensure that each slide is paired with the corresponding cutting groove 6 and the cutter, so that the cutting force distribution is more uniform, the unevenness and errors that may occur during the cutting process are reduced, and the cutting quality is improved. Obviously, at least six slides are provided, so that multiple strips of paper can be cut at the same time, which greatly improves the cutting efficiency. The design of multiple knife positions is suitable for mass production and helps to significantly improve the work efficiency of the production line.
[0037] It should be noted that after any cutter is limited to the cutting position, its knife portion 13 and the corresponding cutting groove 6 are mutually offset, so as to be suitable for cutting out paper of a preset width. In this embodiment, the position of the cutting groove 6 is fixed, in order to ensure that the knife portion 13 can cooperate with cutting after adjusting any position, the two can also be offset from each other, which is more suitable for the arbitrary adjustment of the position of the cutter.
[0038] In other embodiments, the knife portion 13 and the corresponding cutting groove 6 can also cut paper when they are facing each other. This is a prior art and will not be described in detail here.
[0039] In this embodiment, the end of the roller 4 is connected to a driving member 14 for driving the roller 4 to keep the axis rotating during the cutting process. The roller 4 is driven to rotate by the driving member 14, so that the transmitted paper can be continuously transmitted in the paper cutting channel.
[0040] like Figure 2 and Figure 5 As shown, the frame 1 is a gantry frame structure, the conveying unit 2 is configured at least on one side and the top side of the gantry frame structure in the form of transmission by a rubber roller 15, and the roller 4 and the tool holder 5 are arranged front and back on the other side of the gantry frame structure. Among them, the conveying unit 2 is configured on one side and the top of the frame in the form of transmission by a rubber roller, which not only saves the occupied space, but also makes the paper smoother during the transmission process, reduces the waiting time between the paper transmission and cutting, and improves the work efficiency. The roller 4 and the tool holder 5 are arranged front and back on the other side of the gantry frame structure to form a stable cutting channel. When the paper passes through the roller 4, it can be accurately guided to the cutting position, and cooperate with the cutter of the tool holder 5 to perform efficient cutting, ensuring the accuracy and consistency of the cutting.
[0041] In this embodiment, a paper feeding channel is formed between the rubber rollers 15 of the conveying unit 2, and the paper feeding channel is connected to the paper cutting channel to smoothly connect the paper feeding, conveying and cutting of the paper.
[0042] like Figure 2As shown, in this embodiment, a winding unit 16 is provided below the cutting unit 3, and the winding unit 16 is used to wind the cut paper. The winding unit 16 is arranged adjacent to the cutting unit 3, so that the cut paper can directly enter the winding operation, reducing intermediate links and ensuring the continuity and efficiency of the entire production process.
[0043] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
