[0001] This utility model relates to the field of rewinding machine technology, and in particular to a rewinding machine for tablecloth production. Background Technology

[0002] A tablecloth rewinding machine is a device that can further rewind tablecloths that have been rolled onto a roll after production. It includes an unwinding mechanism that releases the tablecloth from the roll and a rewinding mechanism that folds the tablecloth and then rewinds it.

[0003] When rewinding tablecloths using a rewinding machine, the angle at which the folded tablecloth enters the outer surface of the take-up roller may be skewed, causing wrinkles to appear on the surface of the folded tablecloth wound on the outer side of the roller, resulting in a decrease in the rewinding effect of the rewinding machine. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when a folded tablecloth enters the outer surface of the winding roller, the angle of entry may be skewed, resulting in wrinkles on the surface of the folded tablecloth wound on the outer side of the winding roller, which reduces the winding effect of the rewinding machine. Therefore, a rewinding machine for tablecloth production is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rewinding machine for tablecloth production, including an unwinding mechanism and a winding mechanism. The unwinding mechanism includes a folding rod and a machine frame. One end of the machine frame is provided with a rotating unwinding roller and a servo motor for driving the unwinding roller to rotate. Several positioning rollers are rotatably provided on the outer surface of the machine frame. The folding rod is fixed to one side of the machine frame of the unwinding mechanism.

[0006] The winding mechanism includes a frame and a directional roller. One end of the frame is equipped with a winding roller and a servo motor for driving the winding roller to rotate. The directional roller is rotatably mounted on the frame of the winding mechanism below the folding rod. One side of the frame of the winding mechanism is equipped with an anti-wrinkle device to reduce the folding of the tablecloth as it enters the surface of the winding roller and causes skewing.

[0007] Furthermore, the anti-wrinkle device includes a frame plate, which is fixed to one side of the equipment frame of the winding mechanism and located below the winding roller. Two grooved rods are fixedly connected to the top of the frame plate, and a sliding rod is slidably connected to the inner wall of the grooved rod. Two springs are provided at the bottom of the sliding rod, and the upper and lower ends of the two springs are fixedly connected to one end of the sliding rod and the bottom end of the inner wall of the grooved rod, respectively. A support rod is fixedly connected to the top of the sliding rod, and the top of the support rod is arc-shaped.

[0008] Furthermore, metal auxiliary plates are provided at the two sides of the top end of the support rod, and the outer edge of the auxiliary plates is arc-shaped.

[0009] Furthermore, positioning blocks are fixedly connected to both sides of the slide rod, and the positioning blocks slide on both sides of the inner wall of the groove rod.

[0010] Furthermore, the anti-wrinkle device also includes two stops, and the two sides of the support rod are respectively provided with sliding grooves. The bottom ends of the two stops slide on the inner walls of the two sliding grooves respectively. One end of the stop is fixedly connected to a threaded cylinder, and one side of the support rod is rotatably connected to a screw. The two ends of the screw are provided with threads in opposite directions, and the outer surface of the screw is threadedly connected to the inner wall of the threaded cylinder.

[0011] Furthermore, a cylinder is fixedly connected to the outer surface of the screw, and the outer surface of the cylinder is provided with several anti-slip protrusions.

[0012] Furthermore, a rotating shaft is rotatably connected to the top end of the threaded cylinder, a limiting plate is fixedly connected to the outer surface of the rotating shaft, a coil spring is provided at one end of the rotating shaft, and the two ends of the coil spring are fixedly connected to the outer surface of the rotating shaft and the outer surface of the threaded cylinder, respectively.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, an anti-wrinkle device is installed. A vertically movable support rod is installed at the bottom of the take-up roller of the take-up mechanism. The tablecloth entering the outer surface of the take-up roller moves at the top of the support rod. As the tablecloth continues to enter the outer surface of the take-up roller, the slide rod slides inside the groove rod and moves to a different position. A spring pushes the slide rod and the support rod upward so that the support rod can fit against the outer surface of the tablecloth, pressing the tablecloth entering the outer surface of the take-up roller tightly. This minimizes the problem of wrinkles and skewing of the tablecloth entering the outer surface of the take-up roller, thus improving the stability of the rewinding machine during use.

[0020] Example 1, as Figure 1-2 As shown, a rewinding machine for tablecloth production includes an unwinding mechanism 1 and a winding mechanism 3. The unwinding mechanism 1 includes a folding rod 4 and a frame. One end of the frame is equipped with a rotating unwinding roller and a servo motor for driving the unwinding roller. Several positioning rollers are rotatably mounted on the outer surface of the frame. The folding rod 4 is fixed to one side of the frame of the unwinding mechanism 1. The winding mechanism 3 includes a frame and a directional roller 5. One end of the frame is equipped with a winding roller and a servo motor for driving the winding roller. The directional roller 5 is rotatably mounted on the frame of the winding mechanism 3 below the folding rod 4. One side of the frame of the winding mechanism 3 is equipped with an anti-wrinkle device 2 to reduce the skewing and wrinkling caused by the folded tablecloth entering the surface of the winding roller. When using the rewinding machine, the tablecloth roll is... Located on the outer surface of the unwinding roller of the unwinding mechanism 1, the tablecloth output roll is pulled through several positioning rollers of the unwinding mechanism 1 and rests on the surface of the folding rod 4. Then, the middle position of one end of the tablecloth contacts the bottom end of the folding rod 4 and is folded in the middle. Then, the folded end passes through the outer surface of the directional roller 5 and several positioning rollers of the unwinding mechanism 1, enters the outer side of the roll sleeved on the take-up roller and is fixed. Then, the servo motor is controlled by the control box on the outside of the unwinding mechanism 1 and the take-up mechanism 3. The servo motor drives the unwinding roller and the take-up roller to rotate respectively. When the tablecloth on the outer surface of the unwinding roller is released and enters the outer surface of the folding rod 4 for output, the tablecloth will become double-folded due to the positional relationship between the folding rod 4 and the directional roller 5. Then, it passes through the outer surface of several positioning rollers and enters the outer side of the roll on the outer surface of the take-up roller for winding.

[0021] Reference Figure 1-4As shown in this embodiment: the anti-wrinkle device 2 includes a frame plate 21, which is fixed to one side of the equipment frame of the winding mechanism 3 and located below the winding roller. Two grooved rods 22 are fixedly connected to the top of the frame plate 21. A sliding rod 24 is slidably connected to the inner wall of the grooved rods 22. Two springs 23 are provided at the bottom of the sliding rods 24. The upper and lower ends of the two springs 23 are fixedly connected to one end of the sliding rod 24 and the bottom end of the inner wall of the grooved rod 22, respectively. A support rod 25 is fixedly connected to the top of the sliding rod 24. The top of the support rod 25 is arc-shaped. By setting the support rod 25, when the rewinding machine is working, the folded tablecloth enters the outer side of the drum, which is sleeved on the outer surface of the winding roller, and then enters between the drum and the support rod 25. During the rotation of the drum by the winding roller, the tablecloth moves at the top of the support rod 25, flattening the surface of the tablecloth and preventing wrinkles. Simultaneously, as the number of tablecloths on the outer side of the drum increases... This causes the diameter to expand. As the tablecloth enters the outer surface of the roll, it pushes the support rod 25 to slide downward through the slide rod 24 on the inner wall of the groove rod 22 and compresses the spring 23. The elastic force of the spring 23 pushes the slide rod 24 so that the top of the support rod 25 is always in contact with the tablecloth surface on the outer side of the roll, pressing the tablecloth tightly. By setting the anti-wrinkle device 2, and by installing the support rod 25, which can move up and down, at the bottom of the take-up roller of the take-up mechanism 3, the tablecloth entering the outer surface of the take-up roller moves at the top of the support rod 25. As the tablecloth continues to enter the outer surface of the take-up roller, the slide rod 24 slides and moves inside the groove rod 22. The spring 23 pushes the slide rod 24 and the support rod 25 upward so that the support rod 25 can be in contact with the outer surface of the tablecloth, pressing the tablecloth entering the outer surface of the take-up roller tightly. This avoids the problem of wrinkles and skewing of the tablecloth entering the outer surface of the take-up roller as much as possible, and improves the stability of the rewinder during use.

[0022] Reference Figure 2-4 As shown in this embodiment: metal auxiliary plates 26 are provided on both sides of the top edge of the support rod 25. The outer edge of the auxiliary plate 26 is arc-shaped. By setting the arc-shaped metal auxiliary plate 26, it is easier for the tablecloth to enter the top surface of the support rod 25 and it will not be worn by the top edge of the support rod 25. Positioning blocks 27 are fixedly connected to both sides of the slide rod 24. The positioning blocks 27 slide on both sides of the inner wall of the groove rod 22. When the slide rod 24 moves up and down, the positioning blocks 27 on both sides will slide on both sides of the inner wall of the groove rod 22, further limiting the angle between the slide rod 24 and the groove rod 22 to avoid the angle deviation between the slide rod 24 and the support rod 25.

[0023] Reference Figure 2-4As shown in this embodiment: the anti-wrinkle device 2 also includes two stops 29. The two sides of the support rod 25 are respectively provided with sliding grooves 28. The bottom ends of the two stops 29 slide on the inner walls of the two sliding grooves 28 respectively. One end of the stop 29 is fixedly connected to a threaded cylinder 211. One side of the support rod 25 is rotatably connected to a screw 210. The two ends of the screw 210 are provided with threads in opposite directions. The outer surface of the screw 210 is threadedly connected to the inner wall of the threaded cylinder 211. After the roll for winding the tablecloth is sleeved on the outer surface of the winding roller, the screw 210 on one side of the support rod 25 can be pushed to rotate to control the threaded cylinders 211 at one end of the two stops 29 to move in the same direction on the outer surface of the screw 210. This makes the sides of the two stops 29 close to each other fit against the two ends of the roll respectively. The stops 29 further restrict the position of the tablecloth on both sides entering the surface of the roll, thereby improving the anti-wrinkle and anti-deviation effect of the tablecloth.

[0024] Reference Figure 2-4 As shown in this embodiment: a cylinder 212 is fixedly connected to the outer surface of the screw 210. Several anti-slip protrusions are provided on the outer surface of the cylinder 212. By pressing against the anti-slip protrusions on the outer surface of the cylinder 212, it is easier to push the cylinder 212 to control the rotation of the screw 210 and adjust the position of the stop block 29. A rotating shaft 213 is rotatably connected to the top of the threaded cylinder 211. A limit plate 215 is fixedly connected to the outer surface of the rotating shaft 213. A coil spring 214 is provided at one end of the rotating shaft 213. The two ends of the coil spring 214 are respectively connected to the outer surface of the rotating shaft 213 and... The outer surface of the threaded cylinder 211 is fixedly connected. When the screw 210 is rotated to control the movement of the two stops 29, it pulls the limiting plate 215 on one side of the two threaded cylinders 211 to move away from the support rod 25. After the position of the stops 29 is moved, the limiting plate 215 is released. The coil spring 214 at one end of the rotating shaft 213 drives the rotating shaft 213 and the limiting plate 215 to rotate towards the support rod 25, so that one end of the limiting plate 215 abuts against the outer surface of the support rod 25. This can further restrict the position of the stops 29 on the support rod 25 and improve the stability of the stops 29 when they are in action.

[0025] Working principle: When using the rewinding machine, the roll of the take-up tablecloth is placed on the outer surface of the unwinding roller of the unwinding mechanism 1. The tablecloth output roll is pulled through several positioning rollers of the unwinding mechanism 1 and rests on the surface of the folding rod 4. Then, the middle position of one end of the tablecloth contacts the bottom end of the folding rod 4 and is folded in the middle. The folded end is then passed through the outer surface of the directional roller 5 and several positioning rollers of the unwinding mechanism 1, enters the outer side of the roll sleeved on the take-up roller, and is fixed. The screw 210 on one side of the support rod 25 is pushed to rotate, controlling the threaded cylinder 211 at one end of the two stops 29 to move in the same direction on the outer surface of the screw 210, so that the sides of the two stops 29 that are close to each other are respectively attached to the two ends of the roll. Then, the servo motor is controlled by the control box outside the unwinding mechanism 1 and the take-up mechanism 3 to operate, and the unwinding roller and the take-up roller are rotated by the servo motor respectively. When the tablecloth on the outer surface of the roller is released and enters the outer surface of the folding rod 4, the tablecloth will be double-folded due to the positional relationship between the folding rod 4 and the directional roller 5. After passing through the outer surface of several positioning rollers, it enters the outer side of the take-up roller for winding. After the folded tablecloth enters the outer side of the take-up roller, it will enter between the take-up roller and the support rod 25. During the rotation of the take-up roller, the tablecloth will move at the top of the support rod 25. The support rod 25 flattens the surface of the tablecloth to prevent wrinkles. At the same time, the increase in the number of tablecloths on the outer side of the roller will cause the diameter to expand. As the tablecloth enters the outer surface of the roller, it will push the support rod 25 to slide down the inner wall of the groove rod 22 through the slide rod 24 and compress the spring 23. The elastic force of the spring 23 pushes the slide rod 24 to keep the top of the support rod 25 in contact with the tablecloth surface on the outer side of the roller, pressing the tablecloth tightly.
