Description

Technical Field

[0001] The present invention relates to the technical field of rewinding machines, and specifically to a full-automatic four-axis exchange rewinding machine. Background Art

[0002] A rewinding machine is a special equipment for materials such as paper, mica tape, and film. With the rapid development of the papermaking and packaging industries, the processing efficiency requirements for rewinding materials such as paper and plastic film are getting higher and higher, and a full-automatic four-axis exchange rewinding machine is needed; when the existing rewinding machine is in use, the rewinding shaft is usually set as a fixed structure, so that when replacing the rewinding shaft of the fixed structure, additional adjustment or repositioning is required, which reduces the flexibility of the equipment to a certain extent.

[0003] To facilitate overcoming the above defects, the prior art (Chinese patent with application number 202120130401.4 and application date January 18, 2021) discloses a cutting shaft installation and fixing exchange disc applicable to a full-automatic four-axis pipe cutting machine, including a cutting shaft body, an exchange disc body, a motor, and an external body. It is characterized in that: one side of the external body is movably provided with an exchange disc body through a shaft, the exchange disc body is provided with installation screw holes, and a plurality of installation screw holes are provided on the exchange disc body. One side of the exchange disc body is provided with a first connection disc, and four first connection discs are provided on the exchange disc body. Fixing bolts are arranged on the exchange disc body through threads, and four fixing bolts are arranged on the first connection disc. In the present invention, by rotating the adjusting bolt, the adjusting bolt will drive the fixed clamp block to move, and then insert the cutting shaft body into the limiting hole. By rotating the adjusting bolt, the adjusting bolt will drive the fixed clamp block to clamp the cutting shaft body, achieving the purpose of convenient installation of the cutting shaft body.

[0004] Although the prior art can solve the installation of the cutting shaft body, the disc is mainly used for the installation and fixation of the cutting shaft, and does not have a full-automatic four-axis exchange function, so the automatic switching operation between the four cutting shafts cannot be realized, and the paper cannot be prevented from being slack or broken, resulting in the paper being easily slack or broken during the rewinding process of the cutting shaft, and the paper roll cannot be cut, so manual operation by the staff is required, which not only increases the complexity of the operation, but also increases the working time of the full-automatic four-axis pipe cutting machine.

[0005] Therefore, we have proposed a full-automatic four-axis exchange rewinding machine that can well solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a fully automatic four-axis exchange rewinder to solve the problems proposed in the above background technology. Currently, when the cutting shaft is installed and fixed on the exchange disc, the disc is mainly used for the installation and fixation of the cutting shaft and does not have a fully automatic four-axis exchange function. Therefore, the automatic switching operation between the four cutting shafts cannot be realized, and the paper cannot be prevented from being slack or broken. As a result, during the rewinding process of the paper by the cutting shaft, the paper is prone to slack or breakage, and the paper roll cannot be cut. Therefore, manual operation by the staff is required, which not only increases the complexity of the operation but also increases the working time of the fully automatic pipe cutting machine.

[0007] To achieve the above object, the present invention provides the following technical solution: A fully automatic four-axis exchange rewinder includes a frame. A servo motor body is arranged on the left side of the frame. The output shaft of the servo motor body is fixedly installed with a rotating rod through a coupling. A belt is rotatably connected to the outer wall of the rotating rod. The bottom of the belt is drivingly connected to a rotating rod.

[0010] As a preferred technical solution of this application, the connection between the first flange and the second flange is a detachable connection. The first flange and the second flange are both threadedly connected to the bolts. By manually pulling out the bolts connected to the rewinding rod that need to be disassembled and assembled, the second flange is separated from the first flange, so as to quickly replace the used rewinding rod.

[0011] As a preferred technical solution of the present application, the movable frame is movably connected between the fixed rod and the movable groove. The movable frame and the fixed rod are closely attached to the spring, and the movable frame is arranged in an L-shaped structure. The movable frame is driven by the tension roller to move upward in the fixed rod and the movable groove. At the same time, the movable frame squeezes the spring to adapt to the change of the paper roll.

[0012] As a preferred technical solution of the present application, the threaded sleeve is movably connected to the screw rod, and the threaded sleeve is arranged in an irregular shape structure. The threaded sleeve is slidably connected to the chute. During the movement of the threaded sleeve, it slides in the chute to increase the stability and steadiness of the movement of the threaded sleeve.

[0013] As a preferred technical solution of the present application, the cutting knife is driven by the telescopic cylinder body. The cutting knife is located behind the rewinding rod. The output end of the telescopic cylinder body drives the cutting knife to move downward, so that the cutting knife cuts the paper roll.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: for this fully automatic four-axis exchange rewinder, by setting the turntable, the first flange, the second flange and the bolts, it is convenient to achieve fully automatic four-axis exchange rewinding, greatly improving the production efficiency and the degree of automation.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6 , the present invention provides the following technical solutions:

[0027] Embodiment 1: It is convenient to solve the problem that when the cutting shaft installation and fixed exchange disc on the market is in use, the disc is mainly used for the installation and fixation of the cutting shaft and does not have a full-automatic four-axis exchange function, so the automatic switching operation between the four cutting shafts cannot be realized, and the paper cannot be prevented from being slack or broken, resulting in the problem that the paper is prone to slack or breakage during the rewinding process of the cutting shaft. The full-automatic four-axis exchange rewinder in this embodiment discloses the following technical content, which can be referred to in the appendix Figure 1 - Appendix Figure 5, including a frame 1, a servo motor body 2 is arranged on the left side of the frame 1, a rotating rod 3 is fixedly installed on the output shaft of the servo motor body 2 through a coupling, a belt 4 is rotatably connected to the outer wall of the rotating rod 3, a rotating rod 5 is drivingly connected to the bottom of the belt 4, and a turntable 6 is fixedly installed on the right side of the rotating rod 5; four rewinding seats 7 are fixedly installed on the right side of the turntable 6, a first flange 8 is fixedly connected to the right side of each rewinding seat 7, a second flange 9 is movably connected to the right side of the first flange 8, six bolts 11 are threadedly connected inside the second flange 9, and the ends of the six bolts 11 penetrate through the first flange 8, and a rewinding rod 10 is fixedly installed on the right side of the second flange 9; moving components for tensioning are symmetrically arranged on the inner walls on both sides of the frame 1, the moving components include a support frame 12, a chute 18 is opened on the front of the top of the frame 1, and a cutting component for horizontal movement is arranged on the left side of the top of the frame 1; a moving groove 13 is opened on the inner wall of the support frame 12, fixing rods 14 are symmetrically and fixedly installed inside the moving groove 13, a spring 15 is connected to the outer wall of the fixing rod 14, a moving frame 16 is movably connected to the outer wall of the fixing rod 14, and a tensioning roller 17 is rotatably connected to the inner wall of the moving frame 16; the connection between the first flange 8 and the second flange 9 is detachable, and the connection between the first flange 8 and the second flange 9 and the bolt 11 is threaded; the moving frame 16 is movably connected to both the fixing rod 14 and the moving groove 13, the moving frame 16 and the fixing rod 14 are closely attached to the spring 15, and the moving frame 16 is arranged in an L-shaped structure.

[0028] The rewinding rod 10 connected to the second flange 9 is manually fitted by the staff on the corresponding first flange 8. Then, the bolts 11 are manually inserted through the second flange 9 into the first flange 8, so that the second flange 9 is firmly connected to the first flange 8, completing the installation of the rewinding rod 10 on the turntable 6. The servo motor body 2 is started through an external control panel, and the output shaft of the servo motor body 2 drives the rotating rod 3 to rotate. The rotating rod 3 transmits power to the rotating rod 5 through the belt 4, causing the rotating rod 5 to start rotating. Thus, the rotation of the rotating rod 5 further drives the turntable 6 to rotate. As the turntable 6 rotates, the rewinding rod 10 installed on the turntable 6 will be brought below the tension roller 17 to work. Four first flanges 8 are symmetrically arranged on the turntable 6. When the paper roll on one rewinding rod 10 reaches the predetermined size, the staff installs the idle rewinding rod 10 on the turntable 6 through the bolts 11, makes the turntable 6 continue to rotate, and turns the installed idle rewinding rod 10 to the working position. Thus, the used rewinding rod 10 is turned out. The staff manually pulls out the bolts 11 connecting the rewinding rod 10 to be disassembled and assembled, separating the second flange 9 from the first flange 8, so as to quickly replace the used rewinding rod 10, realizing fully automatic four-axis exchange rewinding, greatly improving the production efficiency and automation degree. When the rewinding rod 10 winds the paper roll, the tension roller 17 moves upward following the size of the paper roll on the rewinding rod 10, causing the tension roller 17 to drive the moving frame 16 to move upward in the fixed rod 14 and the moving groove 13. At the same time, the moving frame 16 squeezes the spring 15 to adapt to the change of the paper roll. Thus, the tension roller 17 can make an adaptive adjustment according to the size change of the paper roll, maintaining the appropriate tension of the paper, ensuring that the paper can be smoothly wound on the rewinding rod 10, and avoiding the situation of paper slack or breakage, thereby improving the working efficiency of the rewinder.

[0029] Embodiment 2: The fully automatic four-axis exchange rewinder in this embodiment discloses the following technical content, which is convenient for subsequent quick replacement of the rewinding rod 10. Reference can be made to the attached Figure 1 and the attached Figure 6 . The cutting assembly includes a rotating motor body 19. The output shaft of the rotating motor body 19 is fixedly installed with a screw rod 20 through a coupling. The outer wall of the screw rod 20 is movably connected with a threaded sleeve 21. The bottom of the threaded sleeve 21 is provided with a telescopic cylinder body 22. The output end of the telescopic cylinder body 22 is fixedly installed with a cutting knife 23; The threaded sleeve 21 is movably connected with the screw rod 20, and the threaded sleeve 21 is arranged in an irregular shape structure. The threaded sleeve 21 is slidably connected with the sliding groove 18; The cutting knife 23 is driven by the telescopic cylinder body 22, and the cutting knife 23 is located behind the rewinding rod 10.

[0030] When the paper roll on the rewinding rod 10 reaches a predetermined size and requires four-axis exchange rewinding, the external control board starts the rotation motor body 19, so that the output shaft of the rotation motor body 19 drives the screw rod 20 to rotate, thereby driving the connected threaded sleeve 21 by the screw rod 20 to move horizontally. During the movement of the threaded sleeve 21, it slides in the chute 18 to increase the stability and steadiness of the movement of the threaded sleeve 21, so that the threaded sleeve 21 drives the cutting knife 23 connected to the telescopic cylinder body 22 to move horizontally. During the movement of the cutting knife 23, the external control board starts the telescopic cylinder body 22, so that the output end of the telescopic cylinder body 22 drives the cutting knife 23 to move downward, thereby cutting the paper roll by the cutting knife 23, which is convenient for the subsequent quick replacement of the rewinding rod 10.

[0031] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
