Description

Technical Field

[0001] The utility model relates to the technical field of slitting and rewinding, in particular to a high-speed slitting and rewinding machine. Background Technique

[0002] The high-speed slitting and rewinding machine is a device widely used in industries such as packaging, printing, papermaking, film, and electrical materials. During the winding process, due to factors such as machines and humans, wrinkles often exist in the wound coils or the number of windings fails to meet the required requirements. At this time, the coil needs to be rewound.

[0003] However, in the prior art, the existing slitting and rewinding machine does not set the automatic adjustment cooperation of the spring and the tensioning tube. During the rewinding process, as the thickness increases and the motor speed remains unchanged, it is easy to cause uneven winding of the coil, resulting in problems such as deviation, uneven overlap, and gaps, affecting the consistency and quality of the finished product. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-speed slitting and rewinding machine to solve the problem that the existing slitting and rewinding machine does not set the automatic adjustment cooperation of the spring and the tensioning tube as mentioned in the above background technique. During the rewinding process, as the thickness increases and the motor speed remains unchanged, it leads to uneven winding of the coil, resulting in problems such as deviation, uneven overlap, and gaps, and further affecting the consistency and quality of the finished product.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The technical scheme of the utility model is as follows: a high-speed slitting and rewinding machine, including a rewinding machine main body and a coil. The front outer surface of the rewinding machine main body is respectively rotatably installed with a winding roller and an unwinding roller. A cutting assembly is further arranged on the front outer surface of the rewinding machine main body. Buffer assemblies are arranged on the outer circumferences of the winding roller and the unwinding roller. The buffer assembly includes a fixed ring fixedly connected to the end of the winding roller. A spring is fixedly connected to the inner side of the fixed ring. The end of the spring far from the fixed ring is fixedly connected to a tensioning tube. The tensioning tube is arranged on the outer circumference of the winding roller. A servo motor is fixedly connected to the inner wall of the rewinding machine main body. The output end of the servo motor is fixedly connected to the end of the winding roller.

[0007] As a preferred implementation manner, the outer circumference of the tensioning tube is uniformly and slidably connected with a convex strip that is narrow outside and wide inside. A collar with a diameter larger than the diameter of the winding roller is fixedly connected to the outside of the convex strip.

[0008] As a preferred implementation manner, an intermediate roller is rotatably connected to the outer surface of the rewinding machine main body. Two limiting pieces are sleeved on the outer circumference of the intermediate roller. The width between the two limiting pieces is the same as the width of the coil.

[0009] As a preferred embodiment, a receiving roller is rotatably mounted on the outer surface of the rewinder main body.

[0010] As a preferred embodiment, the receiving roller is provided as a Teflon shaft.

[0011] As a preferred embodiment, the cutting assembly includes an electric guide rail fixedly installed on the outer surface of the rewinder main body. A sliding block is slidably connected to the outside of the electric guide rail, and a blade is fixedly connected to the bottom of the sliding block.

[0012] As a preferred embodiment, the coil is sequentially wound around the outer circumferences of the unwinding roller, the intermediate roller, the receiving roller, and the tensioning tube.

[0013] As a preferred embodiment, a control panel is provided on the outside of the rewinder main body.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0015] In the present utility model, by controlling the operation of the servo motor, the winding roller is driven to rotate, thereby driving the fixed ring to rotate. As a part of the transmission mechanism, the spring can transmit the torque of the servo motor to the tensioning tube, driving the tensioning tube to rotate, thereby realizing the rewinding operation. As the coil is wound layer by layer on the tensioning tube, the thickness gradually increases, and the linear velocity of the coil needs to be kept constant to ensure uniform winding of the material. The required rotational speed of the winding roller needs to be reduced. Under the torque action of the spring, it can smoothly adapt to the change in the coil thickness, ensuring that the rotational speed of the winding roller gradually slows down, maintaining a stable change in the linear velocity of the coil, reducing the rotational speed fluctuation, enhancing the stability of the rewinding process, ensuring the quality of rewinding, and improving the flatness and consistency of the coil.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-4 As shown, the utility model provides a technical solution: it includes a rewinding machine body 1 and a coil 6, a rewinding roller 2 and an unwinding roller 5 are rotatably installed on the front end outer surface of the rewinding machine body 1, a cutting assembly 9 is also provided on the front end outer surface of the rewinding machine body 1, and a buffer assembly 3 is provided on the periphery of the rewinding roller 2 and the unwinding roller 5, the buffer assembly 3 includes a fixing ring 302 fixedly connected to the end of the rewinding roller 2, a spring 304 is fixedly connected to the inner side of the fixing ring 302, a tensioning tube 301 is fixedly connected to the end of the spring 304 away from the fixing ring 302, the tensioning tube 301 is arranged on the periphery of the rewinding roller 2, a servo motor 11 is fixedly connected to the inner wall of the rewinding machine body 1, and the output end of the servo motor 11 is fixedly connected to the end of the rewinding roller 2.

[0025] In this embodiment, the servo motor 11 is controlled to work, so as to drive the winding roller 2 to rotate, thereby driving the fixing ring 302 to rotate. The spring 304, as a part of the transmission mechanism, can transmit the torque of the servo motor 11 to the tensioning tube 301, driving the tensioning tube 301 to rotate, thereby realizing the rewinding operation. As the coil 6 is wound on the tensioning tube 301 layer by layer, the thickness gradually increases, and the linear speed of the coil 6 needs to be kept constant to ensure uniform winding of the material. The required rotation speed of the winding roller 2 needs to be reduced. Under the action of the torque of the spring 304, it can smoothly adapt to the thickness change of the coil 6, ensure that the rotation speed of the winding roller 2 gradually slows down, and keep the linear speed of the coil 6 stable, thereby enhancing the stability of the rewinding process, ensuring the quality of rewinding, and improving the flatness and consistency of the coil 6.

[0026] Example 2

[0027] like Figures 1-4As shown, evenly slidably connected to the outer periphery of the tensioning tube 301 are convex strips 303 that are narrow on the outside and wide on the inside. Fixedly connected to the outside of the convex strips 303 is a collar 305 with a diameter larger than that of the winding roller 2. The design of the convex strips 303 can effectively fix the position of the material, prevent the material from shifting during the winding process, and improve the stability and uniformity of winding. After the rewinding is completed, the convex strips 303 can be disassembled by simple disassembly and pulling the collar 305, facilitating the taking of the material after rewinding;

[0028] Rotatably connected to the outer surface of the rewinder main body 1 is an intermediate roller 7. Sleeved on the outer periphery of the intermediate roller 7 are two limiting pieces 8. The width between the two limiting pieces 8 is the same as the width of the coil material 6, ensuring that the coil material 6 does not shift during the winding process and guaranteeing the neatness of winding;

[0029] Rotatably installed on the outer surface of the rewinder main body 1 is a receiving roller 4. Further, the receiving roller 4 is provided with a Teflon shaft, which has the characteristics of low friction and high wear resistance, reduces the resistance and wear of the material during the winding process, and extends the service life of the equipment;

[0030] The cutting assembly 9 includes an electric guide rail 901 fixedly installed on the outer surface of the rewinder main body 1. Slidably connected to the outside of the electric guide rail 901 is a sliding block 902. Fixedly connected to the bottom of the sliding block 902 is a blade 903. By controlling the operation of the electric guide rail 901, the sliding block 902 will be controlled to drive the blade 903 to move, precisely cutting the material and facilitating the control of the diameter size of the required material;

[0031] The coil material 6 is sequentially wound around the outer peripheries of the unwinding roller 5, the intermediate roller 7, the receiving roller 4, and the tensioning tube 301 to form a complete winding path; A control panel 10 is provided on the outside of the rewinder main body 1.
