Description

Technical Field

[0001] This utility model relates to the field of paper roll machine technology, specifically, to a paper roll machine. Background Technology

[0002] A paper roll machine is a key piece of equipment in the papermaking industry. It mainly consists of a roll, a drive unit, a tension control system, and a cutting device. Its working principle is that the drive unit drives the roll to rotate, fixing one end of the paper on the roll. As the roll rotates, the paper is gradually wound onto the roll, thus rewinding the paper.

[0003] Currently, most rewinding machines have limit rings on both sides of the rewinding roller for limiting paper winding. These limit rings are mostly fixed by bolts. This means that each time the rolled paper is removed from the rewinding roller, the limit rings need to be disassembled, which is quite troublesome and inconvenient. Moreover, the paper is relatively soft and is prone to wrinkles during winding, thus affecting the quality of paper winding. To address these issues, we provide a paper rewinding machine.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a paper winding machine, including a base 1, a winding assembly 2 for winding paper is provided at the top of the base 1, several sets of tension rollers 11 are installed on the side of the top of the base 1 away from the winding assembly 2 via a support frame, a support assembly 3 for supporting the winding assembly 2 is provided on the side of the top of the base 1 near the winding assembly 2, U-shaped rings 4 are provided on both sides of the winding assembly 2, and a connecting plate 41 is connected to the top of each set of U-shaped rings 4, and a lifting assembly 5 for driving the U-shaped rings 4 to rise and fall is provided on the side of the top of the base 1 near the winding assembly 2, and a mechanism for adjusting the two sets of U-shaped rings 4 is provided on the upper side of the lifting assembly 5. The adjusting component 6 for the spacing between the rings 4, and the winding component 2 include a support plate 21, which is installed on the top of the base 1. A motor 22 is installed on the side of the support plate 21. The output end of the motor 22 passes through the support plate 21 and a winding roller 23 is installed thereon. A connecting shaft 24 is installed at the end of the winding roller 23 away from the support plate 21. This structure allows one end of the paper to pass through several sets of tension rollers 11 and be fixed on the surface of the winding roller 23. Then, the motor 22 can be started to drive the winding roller 23 to rotate. At the same time, the winding roller 23 will also drive the connecting shaft 24 to rotate within the arc frame 33. In this way, the winding roller 23 can wind up the paper.

[0021] As one implementation method in this embodiment, such as Figure 2 and Figure 3As shown, the support assembly 3 includes a sleeve rod 31, which is mounted on the top of the base 1. A movable rod 32 is slidably mounted inside the sleeve rod 31. An arc-shaped frame 33 is mounted on the top of the movable rod 32. A connecting shaft 24 is disposed within the arc-shaped frame 33. A threaded groove 34 is formed on the lower side of the movable rod 32. A threaded hole 35 is formed on the inner wall of the sleeve rod 31 near the threaded groove 34. A one-way screw 36 is threaded into the threaded groove 34 and the threaded hole 35. A handle 37 is mounted on the outer end of the one-way screw 36. This structure allows... By grasping and rotating handle 37, the one-way screw 36 rotates within the threaded hole 35 and threaded groove 34. Through this rotation, the two-way screw 63 is moved out of the threaded groove 34 and threaded hole 35, releasing the lock on the movable rod 32. This allows the movable rod 32 to move downwards within the sleeve 31 due to gravity. The movable rod 32 then moves the arc-shaped frame 33 away from the connecting shaft 24, thus removing the obstruction at one end of the winding roller 23, making it easier to remove the wound paper. (Lifting assembly) The base 1 includes several sets of support rods 51, each set mounted on the top of the base 1. A top plate 52 is mounted on the top of each set of support rods 51, and a cylinder 53 is mounted on the top of the top plate 52. An adjusting assembly 6 is located at the bottom of the cylinder 53. Two sets of connecting plates 41 are mounted on both sides of the bottom of the adjusting assembly 6. This structure allows the starting cylinder 53 to move the adjusting assembly 6 upward, which in turn moves the two sets of connecting plates 41. The two sets of connecting plates 41 then move the two sets of U-shaped rings 4 upward until the two sets of U-shaped rings 4... Moving the U-rings away from the take-up roller 23 allows for easy removal of the rolled paper. Conversely, starting the cylinder 53 moves the adjusting component 6 downwards, which in turn moves the two connecting plates 41 downwards until the two U-rings 4 are secured to both sides of the surface of the take-up roller 23. This completes the installation of the U-rings 4, allowing them to limit the winding of the paper and resulting in a neater roll.

[0022] As one implementation method in this embodiment, such as Figure 4As shown, the adjusting assembly 6 includes a mounting rod 61, which is mounted on the bottom end of the cylinder 53. A groove 62 is formed at the bottom end of the mounting rod 61, and a bidirectional screw 63 is rotatably mounted inside the lower side of the groove 62. A second motor 64 is mounted on the outer wall of the mounting rod 61, and the output end of the second motor 64 is connected to one end of the bidirectional screw 63. Movable sleeves 65 are threaded onto both sides of the surface of the bidirectional screw 63. Each set of connecting plates 41 is mounted on the bottom end of the movable sleeves 65. This structure allows the second motor 64 to drive the bidirectional screw 63 to rotate. Through the threaded rotation, the bidirectional screw 63 drives the two sets of movable sleeves 65 to move in opposite directions. In this way, the two sets of movable sleeves 65 can drive the two sets of connecting plates 41, and the two sets of connecting plates 41 can drive the two sets of U-shaped rings 4 to move in opposite directions. This allows the distance between the two sets of U-shaped rings 4 to be adjusted according to different sizes of paper, thus limiting the winding of the paper. This makes the device suitable for more different sizes of paper. A limit rod 66 is fixedly installed on the upper side of the inside of the slide groove 62. The upper side of the movable sleeve 65 is slidably fitted with the surface of the limit rod 66, so that the movable sleeve 65 will also slide along the limit rod 66 when it moves. This limits the movable sleeve 65 and makes the movable sleeve 65 move more stably laterally.

[0023] As one implementation method in this embodiment, such as Figure 4 As shown, each of the two sets of connecting plates 41 is provided with a leveling component 7 for leveling the paper at one end close to each other. Each leveling component 7 includes a fixing plate 71. Each fixing plate 71 is mounted on the side end of the connecting plate 41. Each fixing plate 71 has a sliding rod 72 slidably mounted on both sides. Each pair of sliding rods 72 has a mounting bracket 73 mounted at the bottom end. Each sliding rod 72 has a spring 74 sleeved on the lower side of its surface. Each mounting bracket 73 has a leveling roller 75 rotatably mounted inside it.

[0024] It should be noted that the two sets of leveling components 7 are staggered, so that the two sets of leveling components 7 can move and adjust with the two sets of connecting plates 41, which is more convenient.

[0025] Working principle: In use, one end of the paper is passed through several sets of tension rollers 11 and fixed to the surface of the take-up roller 23, with the bottom ends of the two sets of leveling rollers 75 pressed against the surface of the paper. Then, the motor 22 is started to drive the take-up roller 23 to rotate. At the same time, the take-up roller 23 also drives the connecting shaft 24 to rotate within the arc frame 33. In this way, the take-up roller 23 can wind up the paper. During winding, the elastic force of the spring 74 pushes the mounting frame 73 downward, which drives the leveling roller 75 downward, so that the leveling roller 75 is pressed against the surface of the paper. This can press down the wound paper and level it, making the wound paper less prone to wrinkles. As the paper rolls thicker, it pushes the leveling roller 75 upward, which drives the mounting frame 73. The mounting frame 73 drives the slide bar 72 to slide upward. The spring 74 is compressed, which allows the mounting frame 73 to move downwards. The mounting frame 73 drives the leveling roller 75 to better fit the paper, allowing the leveling roller 75 to be adjusted according to the thickness of the paper being wound, greatly increasing the practicality of the device. At the same time, if it is necessary to adjust the distance between the two sets of U-shaped rings 4 according to different paper sizes, simply start the motor 64 to drive the bidirectional screw 63 to rotate. Through the screw rotation, the bidirectional screw 63 drives the two sets of movable sleeves 65 to move in opposite directions. The two sets of movable sleeves 65 will also slide along the limit rod 66. In this way, the two sets of movable sleeves 65 can drive the two sets of connecting plates 41, and the two sets of connecting plates 41 can drive the two sets of U-shaped rings 4 to move in opposite directions. In this way, the distance between the two sets of U-shaped rings 4 can be adjusted according to different paper sizes, making the device suitable for more different paper sizes.

[0026] After the paper is wound up, if you need to remove the wound paper from the winding roller 23, simply start the cylinder 53 to move the adjusting component 6 upward. The adjusting component 6 moves the two sets of connecting plates 41, and the two sets of connecting plates 41 move the two sets of U-shaped rings 4 upward until the two sets of U-shaped rings 4 are away from the winding roller 23. This allows the U-shaped rings 4 to be removed from the winding roller 23, making it easier to remove the wound paper. Then, you can hold the handle 37 and turn it. The handle 37 drives the one-way screw 36 to rotate inside the threaded hole 35 and the threaded groove 34. Through the rotation of the thread, the two-way screw 63 is moved out of the threaded groove 34 and the threaded hole 35, which unlocks the movable rod 32. The movable rod 32 moves downward inside the sleeve rod 31 due to gravity. This allows the movable rod 32 to move the arc frame 33 away from the connecting shaft 24. Finally, the wound paper can be removed from the end of the connecting shaft 24.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
