AI Technical Summary
The existing film coiling machines are uneven in thickness due to unbalanced winding pressure of the machine, which is prone to wrinkles and gas wrapping. The yield is low, and the traditional coiling machine has no positioning. It is easy to jump when the winding speed is fast, so it cannot be effectively coiled.
A fully automatic low tension film winder is designed, including a tension adjustment assembly, a winding assembly and a floating positioning assembly. The tension adjustment assembly adjusts the film tension through an active friction roller and a driving motor. The winding assembly stabilizes the winding assembly by a passive friction roller and an active pressing roller. The floating positioning assembly realizes positioning and compression of the winding shaft through the guide rail and the cylinder.
The constant tension of the film is achieved, which avoids the film being pulled and wrinkled during the winding process, ensures the stability of the rolling shaft, avoids the gas wrapping phenomenon, and improves the winding quality and production efficiency.

[0018] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments.

[0019] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0020] The terms “upper”, “lower”, “front”, “back”, “left” and “right” in this application refer to the attached Figure 1 Up, down, front, back, left and right as shown.
[0021] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
[0022] The present application embodiment provides a fully automatic low tension film winding machine, such as Figure 1 As shown, the winder 100 is suitable for low-tension winding of ultra-thin TPU films. The winder 100 comprises a frame 1, a winding device 2 arranged on the frame 1, a storage station 3, a crane 4, a roll unloading mechanism 5, a cutting device 6 and a control device.
[0023] The frame 1 includes a pair of wall panels 11 disposed opposite to each other on the left and right sides, and a plurality of supporting beams are disposed between the pair of wall panels 11, so that the frame 1 supports various devices of the winder 100 on the production line.
[0024] like Figure 3As shown, the winding device 2 includes a tension adjustment component 21, a winding component 22 and a floating positioning component 23. The tension adjustment component 21 includes an active friction roller 211 and a first drive motor 212 drivingly connected to the active friction roller 211. The active friction roller 211 is extended along the left and right directions and is arranged on a pair of wall panels 11. The first drive motor 212 is used to drive the active friction roller 211 to rotate around its own axis and adjust the rotation speed of the active friction roller 211.
[0025] like Figure 3 , 8 As shown in Figures 9 and 10, the winding assembly 22 includes a winding shaft clamping plate 221 for carrying the winding shaft 8, a passive friction roller 222 and an active pressure roller 223 rotatably arranged on the winding shaft clamping plate 221, a second driving motor 224 drivingly connected to the active pressure roller 223, and a first cylinder 225 connected to the winding shaft clamping plate 221. The winding shaft clamping plate 221 is provided with a positioning groove 2210 for the winding shaft 8 to move, the opening 2211 of the positioning groove 2210 faces the rear side of the winding device 2, the groove bottom 2212 of the positioning groove 2210 is located at the front side of the opening 2211, and the winding shaft 8 can be inserted into the positioning groove 2210 both slidably and rotatably; the winding shaft clamping plate 221 has a guide slope 2213 at the opening 2211, and the guide slope 2213 extends from the lower end of the opening 2211 to the rear side. The passive friction roller 222 and the active pressure roller 223 are both arranged in parallel with the active friction roller 211. The passive friction roller 222 and the active pressure roller 223 are rotatably arranged on the reel card plate 221. The passive friction roller 222 is arranged close to the active friction roller 211, and the active pressure roller 223 is arranged close to the groove bottom 2212 of the positioning groove 2210. There is a distance between the passive friction roller 222 and the active pressure roller 223. The second driving motor 224 is arranged on the reel card plate 221, and is used to drive the active pressure roller 223 to rotate around its own axis and adjust the rotation speed of the active pressure roller 223. The first cylinder 225 is transmission-connected between the frame 1 and the reel card plate 221. The first cylinder 225 is used to drive the reel card plate 221 to swing relative to the frame 1 to adjust the distance between the surface of the passive friction roller 222 and the surface of the active friction roller 211. The active friction roller 211 is located in front of the active pressing roller 223 , and the passive friction roller 222 is located between the active friction roller 211 and the active pressing roller 223 .
[0026] The reel clamping plate 221 has a swing range under the drive of the first cylinder 225. The opening 2211 of the positioning groove 2210 is always located on the upper side of the groove bottom 2212 within the swing range of the reel clamping plate 221, ensuring that the reel 8 is always contained in the groove bottom 2212 of the positioning groove 2210 without the influence of external force during the reeling process. During the first reeling, the first cylinder 225 drives the reel clamping plate 221 to lift upward, and the film passes between the active friction roller 211 and the passive friction roller 222. When the film is rolled up onto the reel 8 in the positioning groove 2210, the first cylinder 225 drives the reel clamping plate 221 to descend, and the passive friction roller 222 presses the film against the active friction roller 211.
[0027] The floating positioning assembly 23 includes a guide rail 231 extending along the positioning groove 2210, a floating block 232 cooperatively connected to the guide rail 231, and a second cylinder 233 for providing a constant pressure pressed against the active pressure roller 223 to the winding shaft 8 in the positioning groove 2210. The floating block 232 can be arranged on the winding shaft clamping plate 221 so as to move back and forth along the guide rail 231. The floating block 232 abuts against the front side of the winding shaft 8 when the winding shaft 8 is located in the positioning groove 2210. The cylinder body of the second cylinder 233 is fixed on the frame 1, and one end of the piston rod of the second cylinder 233 is rotatably connected to the floating block 232. The floating block 232 is configured to drive the winding shaft 8 in the positioning groove 2210 to move back and forth along the positioning groove 2210.
[0028] The floating positioning assembly 23 further includes a stopper 234 movably disposed on the floating block 232 and a positioning cylinder 235 driving the stopper 234 to move. When the winding assembly 22 is winding, the stopper 234 is in a shielding position for shielding the winding shaft 8 at the opening side of the positioning groove 2210 (see Figure 3 ), after the winding is completed, it is driven by the positioning cylinder 235 to leave the shielding position (see Figure 4 ), the reel 8 can leave the reel clamping plate 221 through the opening 2211 of the positioning groove 2210.
[0029] The second cylinder 233 is a proportional valve cylinder, and the second cylinder 233 drives the reel 8 to approach and move away from the active pressure roller 223 through air intake and air discharge. During the reeling process of the reel 8, the total thickness of the film wound on the reel 8 becomes larger and larger, so that the reel 8 gradually moves away from the active pressure roller 223. The floating positioning assembly 23 is used to limit the reel 8 in the positioning groove 2210 and press the reel 8 against the active pressure roller 223 to prevent the reel 8 from jumping during the reeling process and causing air to be trapped in the film during the reeling process. During the winding process, the positioning cylinder 235 drives the block 234 to move to the blocking position, and the block 234 limits the two ends of the winding shaft 8 in the floating block 232 and the positioning groove 2210. As the thickness of the film increases, the winding shaft 8 gradually moves away from the active pressure roller 223. At this time, the second cylinder 233 gradually takes in air, and while ensuring that the distance between the winding shaft 8 and the active pressure roller 223 is adapted to the total thickness of the currently wound film, a pressure is applied to the rear side of the winding shaft 8 through the block 234 to press it against the active pressure roller 223 to prevent the winding shaft 8 from jumping; the second cylinder 233 takes in air stably to ensure that the pressure of the winding shaft 8 pressing against the active pressure roller 223 is constant, to avoid air inclusion between the wound film, and to make the film on the winding shaft 8 densely wound, thereby improving the winding quality. The air intake of the second cylinder 233 can be adjusted according to the type of film being wound to ensure that different films are wound densely and improve the winding quality.
[0030] like Figure 6 , 9 , 12, the first drive motor 212, the second drive motor 224, the first cylinder 225, the second cylinder 233 and the positioning cylinder 235 are all connected to the control device 7 by signal, and the control device 7 controls the start and stop; the film to be rolled up successively snakes around the active friction roller 211, the passive friction roller 222, and the active pressure roller 223 and is then rolled up on the winding shaft 8 located in the positioning groove 2210 (see Figure 6 ), the first drive motor 212 and the second drive motor 224 adjust the speed difference according to the thickness of the film under the control of the control device 7, so that there is a sliding friction between the film and the active pressure roller 223 and the winding shaft 8, ensuring that the film is wound at a constant low tension, avoiding the film from being pulled and wrinkled during the winding process; the positioning groove 2210 and the floating positioning component 23 cooperate to limit the position of the winding shaft 8 on the winding shaft clamping plate 221, avoiding the winding shaft 8 from jumping during high-speed winding, and winding smoothly. The winding device 2 effectively eliminates the problem of film air encapsulation, which is conducive to the dense winding of the film on the winding shaft 8.
[0031] like Figure 2 , 10As shown in Figures 1 and 11, the storage station 3 is located downstream of the winding device 2 and is used to store and limit the winding shaft 8 that has been wound up. The storage station 3 includes a friction assembly 31 for storing the winding shaft 8 that has been wound up and a shaft positioning assembly 32 for limiting the position of the winding shaft 8. The friction assembly 31 includes a support frame 311, a first friction roller 312 and a second friction roller 313 rotatably arranged on the support frame 311, a third cylinder 314 for driving the support frame 311 to rise and fall, and a third drive motor 315 connected to the first friction roller 312 and the second friction roller 313; the first friction roller 312 and the second friction roller 313 both extend in the left-right direction and are arranged opposite to each other front and back, and there is a gap between them, so as to facilitate the stable storage of the winding shaft 8; the third drive motor 315 drives the first friction roller 312 and the second friction roller 313 to rotate. The third driving motor 315 and the third cylinder 314 are both connected to the control device 7 by signal. When the film on the winding shaft 8 is wound to a specified length, it is transported to the storage station 3 by the winding device 2. The third cylinder 314 adjusts the height of the support frame 311 based on the thickness of the film on the winding shaft 8. When the winding shaft 8 is carried onto the friction assembly 31, the first friction roller 312 and the second friction roller 313 rotate rapidly, so that the winding shaft 8 rotates quickly to tighten the film between the storage station 3 and the winding device 2, so as to facilitate the cutting device 6 to cut the film. The shaft stop positioning assembly 32 includes a first shaft stop member 321 and a second shaft stop member 322 which can move in the up and down directions, and a fourth cylinder 323 which is connected to the first shaft stop member 321 and the second shaft stop member 322; when the winding shaft 8 is carried onto the friction assembly 31, the first shaft stop member 321 and the second shaft stop member 322 are raised to block the front and rear sides of the winding shaft 8, and a shaft stop positioning assembly 32 is respectively arranged at the left and right ends of the friction assembly 31 to limit the position of the winding shaft 8 on the friction assembly 31 to prevent the winding shaft 8 from falling during the unloading process.
[0032] like Figure 2 , 5As shown in Figures 6 and 7, the crane 4 is fixedly arranged on the frame 1, and the crane 4 includes a frame 41 extending in the horizontal direction, a lifting cylinder 42 located on the upper side of the positioning groove 2210, and a reel hook 43 that can move forward and backward along the frame 41. The lower end of the piston rod of the lifting cylinder 42 is fixedly connected with a hook 421 for mounting a replacement reel shaft, and the hook 421 is located just above the opening 2211 of the positioning groove 2210. The lifting cylinder 42 is used to drive the hook 421 to extend in the up-down direction; the operator places the replacement reel shaft 8 on the hook 421, and the lifting cylinder 42 lowers the reel shaft 8 on the hook 421 to the guide slope 2213, and the lifting cylinder 42 continues to transport the hook 421 downward, so that the reel shaft 8 falls off the hook 421 and rolls into the positioning groove 2210 along the guide slope 2213. The operator places the unloaded winding shaft 8 on the hook 421 in a safe area to avoid directly rolling the winding shaft 8 into the positioning groove 2210 to affect the winding work, while reducing the danger and ensuring the safety of the operator. The winding hook 43 moves forward and backward along the rack 41 to move the winding shaft 8 with the film cut on the storage station 3 to the outside of the winding machine 100 for the operator to pack.
[0033] like Figure 1 , 2 As shown in Figures 6 and 7, the unloading mechanism 5 is arranged on the left and right sides of the frame, and is used to push the fully rolled reel 8 from the reel 2 to the storage station 3 when the reel 8 of the reel 2 is fully rolled. The unloading mechanism 5 includes a pair of push plates 51 and a push cylinder 52 connected to the pair of push plates 51. The pair of push plates 51 are respectively located on the outside of the reel 2 in a left and right manner. The push cylinder 52 is used to drive the pair of push plates 51 to move back and forth in the front and back directions. The push cylinder 52 drives the pair of push plates 51 to move backward to push the fully rolled reel 8 out of the positioning groove 2210 and continue to push it backward to the storage station 3.
[0034] like Figure 6 , 7 As shown, the cutting device 6 is arranged between the winding device 2 and the storage station 3. The cutting device 6 includes a heating wire 61 and a cutting cylinder 62 that drives the heating wire 61 to move in the up and down directions. When the winding device 2 changes the roll, the cutting cylinder 62 drives the heating wire 61 to rise to cut off the taut film between the winding device 2 and the storage station 3; after the film is cut off, the cutting cylinder 62 immediately drives the heating wire 61 to descend.
[0035] like Fig.12 As shown, the control device 7 is connected to the cylinder and drive motor signals of the winding device 2, the storage station 3, the crane 4, the unloading mechanism 5 and the cutting device 6 to control the start and stop of the cylinder and the drive motor.
[0036] like Figure 6As shown, when the winder 100 is changing the roll, the unloading mechanism 5 pushes the fully rolled winding shaft 8 on the winding shaft clamping plate 221 to the storage station 3, and the lifting cylinder 42 conveys the empty winding shaft 8 to the unloaded positioning groove 2210 under the control of the control device 7, and part of the film between the fully rolled winding shaft 8 and the active pressure roller 223 is pressed between the empty winding shaft 8 and the active pressure roller 223, and the storage station 3 causes the fully rolled winding shaft 8 to rotate to tighten the film between the winding device 2, and the cutting device 6 cuts off the film between the empty winding shaft 8 and the fully rolled winding shaft 8, and the fully rolled winding shaft 8 is unloaded by the winding hook 43; under the friction of the active pressure roller 223, the film is rolled up on the unloaded winding shaft 8 and continues to be rolled.
[0037] The winding machine of the present application has a compact structure and a high degree of automation; the winding device 2 ensures that the film is wound at a constant tension to prevent the film from being pulled and wrinkled during the winding process. The winding device 2 limits the position of the winding shaft 8 during the winding process to prevent the winding shaft 8 from jumping and generating air encapsulation during the winding process. It can adapt to the functions of automatic cutting and automatic winding, effectively improving the winding quality and production efficiency.
