Description

Technical Field

[0001] The invention relates to the technical field of film winding equipment, in particular to a winding device, and in particular to a winding process for polyurethane films of multiple specifications. Background Art

[0002] Polyurethane film has good elasticity and lightness. Although it is very thin, it has excellent waterproofness. It is an environmentally friendly, non-toxic, recyclable and decomposable environmentally friendly material. It does no harm to human skin and has good cold resistance. Therefore, it is widely used in clothing fabrics, medical and health, leather and other fields, becoming the mainstream material in the 21st century. After the polyurethane film is formed, it needs to be rolled up for easy storage and transportation. The batch rolling of the film needs to be completed by automated winding equipment.

[0003] Chinese patent CN113620127B discloses an automatic film winding device for polyurethane film production, which relates to the technical field of film production equipment, including a support seat, a transmission device, a film rolling device, and a push-pull device.

The push-pull device of the device cooperates with the film rolling device, and the diameter of the film rolling device can be changed according to the rolls of different sizes; the push-pull device improves the dynamic balance by hingedly connecting the connecting joints to prevent the occurrence of eccentric load.

[0004] Although the above-mentioned devices have a certain degree of flexibility and can adapt to the installation and fixation of rolls of different sizes, in the actual production process, these devices are often unable to continuously adapt to the fixed rolls, that is, the rolls cannot be automatically replaced during a complete winding process.

[0020] S5. The roll with the tail part attached continues to slide to the area to be processed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This device integrates a multi-specification winding device, an adaptive feeding device, a guide rail and a film roll tail laminating device to achieve a fully automated process from film winding to roll replacement and tail laminating. This innovative design completely changes the inefficient mode of traditional manual roll replacement and tail processing, and significantly reduces the interruption time in the production process. The automatic switching mechanism ensures that when the film winding reaches the preset amount, the replacement of the new and old rolls can be seamlessly connected without stopping and waiting, thereby greatly improving the overall production efficiency.

[0023] 2. The traditional manual reel replacement and tail lamination method is not only time-consuming and labor-intensive, but also increases the reliance on human resources.

[0024] 3. The film roll tail laminating device adopts automatic gluing and laminating technology to ensure the accuracy and consistency of film tail processing. Compared with manual operation, automatic processing can more accurately control the amount and application position of adhesive. This not only improves the appearance quality of the product, but also enhances the stability of the film roll. At the same time, due to the high degree of automation of the entire winding process, the uncertainty caused by human intervention is reduced, making the product quality more stable and reliable.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 10 As shown, a winding device includes a continuous winding device for continuously winding a film, the continuous winding device includes a multi-specification winding device 2, an adaptive loading device 3, a guide unloading rail 4 and a film roll tail bonding device 43, the multi-specification winding device 2 is arranged on the side of the guide frame, the multi-specification winding device 2 is used to adapt to the winding of rolls 1 of different sizes, the adaptive loading device 3 is installed on the side of the multi-specification winding device 2, the adaptive loading device 3 is used to convey the roll 1 to the multi-specification winding device 2, a plurality of guide unloading rails 4 are provided, and are symmetrically installed above the adaptive loading device 3, the guide unloading rail 4 is used to guide the unloading of the roll 1, and the film roll tail bonding device 43 is installed on the guide unloading rail 4.

[0039] The guide frame is used to guide the film to move to the multi-specification winding device 2, which can flexibly adapt to and firmly clamp rolls 1 of different sizes. When the film winding of a roll 1 reaches a preset amount, the multi-specification winding device 2 automatically starts the switching mechanism, smoothly moves the completed roll 1 from the winding area to the unloading area, and at the same time takes out a new roll 1 from the adaptive loading device 3, quickly and accurately moves it to the winding area, and prepares for the next round of winding. The adaptive loading device 3 has a flexible loading system that can adapt to rolls 1 of different sizes and weights. The staff only needs to place multiple unused rolls 1 on the adaptive loading device 3 in order, and the adaptive loading device 3 can ensure that each roll 1 can be accurately delivered to the multi-specification winding device 2. The guide unloading rail 4 is used to ensure the stability and directionality of the roll 1 during the unloading process. When the roll 1 is completed and released by the multi-specification winding device 2, it will slide along the guide unloading rail 4 to the specified position. First, the roll 1 will be guided to the film roll tail laminating device 43 for processing, and then continue to slide to the processing area to wait for subsequent operations or transportation. The film roll tail laminating device 43 is installed at a specific position of the guide unloading rail 4, and is responsible for the automatic gluing and laminating of the tail of the film. When the roll 1 slides to the device, the film roll tail laminating device 43 will first detect the position of the tail of the film, and then automatically apply an appropriate amount of adhesive to the tail, and then accurately fit the glued tail to the outer wall of the film roll to ensure that the edge of the wound film roll is neat. The whole process achieves a high degree of automation and continuity, greatly reduces manual intervention, and improves production efficiency and product quality. The guide frame is a prior art and will not be described here.

[0040] See also Figures 1 to 5As shown, the multi-specification winding device 2 includes a rotating control console 21, on which an adaptive adjustment frame 22 is installed, on which a plurality of symmetrically arranged limit pressing devices 23 are installed, and on which a plurality of rotating drive devices 24 are also installed. The rotating drive devices 24 correspond one to one with the limit pressing devices 23, and the rotating drive devices 24 are used to drive the limit pressing devices 23 to rotate.

[0041] The rotary drive device 24 and the rotary control console 21 are both prior art and will not be described in detail here. The adaptive adjustment frame 22 adjusts the position of the limit pressure device 23 according to the size of the current roll 1 to ensure that rolls 1 of different lengths can be firmly clamped. The limit pressure device 23 is used to fix rolls 1 of different apertures, and is also connected to the corresponding rotary drive device 24 to achieve the rotational winding of the roll 1. The rotary drive device 24 drives the limit pressure device 23 to rotate, thereby driving the clamped roll 1 to rotate and continuously winding the film. When the film winding of a roll 1 reaches a preset amount, the multi-specification winding device 2 will automatically start the switching mechanism. The rotary control console 21 drives the adaptive adjustment frame 22 to rotate to the next preset position, and at the same time the limit pressure device 23 releases the roll 1 that has completed winding and is ready to receive a new roll 1.

[0042] See also Figures 3 to 6 As shown, the adaptive adjustment frame 22 includes an adjustment drive shaft 221 installed on the rotating control console 21, a limit adjustment groove 2211 is provided on the adjustment drive shaft 221, a plurality of adjustment sliders 2213 are provided inside the limit adjustment groove 2211, a bidirectional adjustment screw rod 2212 is also installed in the limit adjustment groove 2211, the bidirectional adjustment screw rod 2212 is threadedly connected with the adjustment slider 2213, a first anti-rotation limit plate 2214 is provided at one end of the bidirectional adjustment screw rod 2212, a first positioning threaded hole 2215 is provided on the first anti-rotation limit plate 2214, a plurality of first limit holes 2216 are provided on one side of the adjustment drive shaft 221, a plurality of limit mounting plates 223 are also installed on the adjustment drive shaft 221, the limit mounting plates 223 are fixedly connected with the adjustment slider 2213, and a plurality of limit guide shafts 222 are installed between the limit mounting plates 223.

[0043] The adjusting drive shaft 221 is provided with a limit adjustment groove 2211, and a plurality of adjustment sliders 2213 are installed in the adjustment groove, and these sliders can slide freely along the track in the groove. The two-way adjustment screw rod 2212 passes through the limit adjustment groove 2211 and is threadedly connected with each adjustment slider 2213. The limit installation disk 223 is used for the limit installation of a plurality of limit pressing devices 23. When the position of the limit pressing device 23 needs to be adjusted, it is convenient for the limit pressing device 23 to fix the reel 1 of different lengths, and the two-way adjustment screw rod 2212 is rotated. Due to the interaction of the threads, the adjustment slider 2213 will move synchronously along the limit adjustment groove 2211. This movement is accurate and can be adjusted according to the needs of reels 1 of different lengths. The limit installation disk 223 is fixedly connected with the adjustment slider 2213, so when the adjustment slider 2213 moves, the limit installation disk 223 will also be adjusted synchronously accordingly. These limit installation disks 223 can be close to or away from each other to adapt to reels 1 of different lengths. In order to ensure that the bidirectional adjustment screw rod 2212 remains stable after the adjustment is completed, the staff can use bolts to fix the first anti-rotation limit plate 2214 on the bidirectional adjustment screw rod 2212 with the first limit hole 2216 on the adjustment drive shaft 221. The first positioning threaded hole 2215 on the first anti-rotation limit plate 2214 provides a precise positioning point to ensure that the bidirectional adjustment screw rod 2212 will not be displaced by external forces, thereby affecting the accuracy of the adjustment.

[0044] When the film winding of a roll 1 reaches a preset amount, the rotating control console 21 can drive the adjusting drive shaft 221 to rotate, and the adjusting drive shaft 221 will drive the limit mounting plate 223 and the limit pressing device 23 to rotate to the next preset position. Since the limit mounting plate 223 and the limit pressing device 23 are adjusted synchronously, the entire switching process is fast and accurate, and automatic switching and winding can be achieved without manual intervention.

[0045] See also Figures 3 to 5 As shown, the limit pressing device 23 includes a limit rotating sleeve 231 rotatably mounted on the limit mounting disk 223, and a limit contact head 232 is slidably mounted inside the limit rotating sleeve 231. The limit pressing device 23 also includes a first linear driver 233 mounted on the limit mounting disk 223, and the output end of the first linear driver 233 is connected to the limit contact head 232.

[0046] The limiting rotating sleeve 231 installed on the limiting mounting disk 223 is rotatably installed inside the limiting rotating sleeve 231. The limiting contact head 232 is a key component, which is used to directly contact the hole on the side of the reel 1, thereby fixing the reel 1. The limiting contact head 232 has strong adaptability and can be adjusted according to the reel 1 with different apertures. When the adaptive feeding device 3 moves the reel 1 to the position of the limiting contact head 232, the first linear drive 233 installed on the limiting mounting disk 223 starts to work, and its output end pushes the limiting contact head 232 to slide along the inside of the limiting rotating sleeve 231 until the limiting contact head 232 is tightly in contact with the hole on the side of the reel 1, thereby firmly positioning the reel 1 at a predetermined position. Once the reel 1 is firmly clamped by the limiting pressing device 23, the corresponding rotary drive device 24 starts to work. The rotation driving device 24 drives the limit rotation sleeve 231 to rotate. When the limit rotation sleeve 231 rotates, it will drive the limit contact head 232 to rotate synchronously. When the limit contact head 232 rotates, it will drive the reel 1 to rotate, so as to realize the winding of the film.

[0047] See also Figures 5 to 7 As shown, a conical anti-slip surface 2321 is provided at one end of the limit contact head 232 away from the first linear drive 233, a plurality of limit slide rails 2322 are provided inside the limit contact head 232, a sliding adjustment block 2323 is also installed inside the limit slide rail 2322, an adjusting screw 2324 is installed at the axial position of the limit slide rail 2322, the adjusting screw 2324 is threadedly connected to the sliding adjustment block 2323, a sliding support rod 2325 is installed in the limit slide rail 2322, an expansion connecting rod 2326 is installed between the sliding support rod 2325 and the sliding adjustment block 2323, a plurality of second limit holes 2329 are provided on the side of the limit contact head 232, a second anti-rotation limit disk 2327 is provided on the side of the adjusting screw 2324, and a second positioning threaded hole 2328 is provided on the second anti-rotation limit disk 2327.

[0048] The sliding support rod 2325 is used to limit the hole of the reel 1. When the position of the sliding support rod 2325 needs to be adjusted to adapt to reels 1 of different sizes, the adjusting screw rod 2324 is rotated. Due to the threaded connection with the sliding adjustment block 2323, the sliding adjustment block 2323 will be driven to move along the limiting slide rail 2322. When the sliding adjustment block 2323 moves, the sliding support rod 2325 will be pushed or pulled for synchronous adjustment through the action of the expansion connecting rod 2326. The sliding support rod 2325 inside the limiting contact head 232 is adaptively adjusted according to the size of the hole of the reel 1 to improve the stability and adaptability of the fixation. When the adjusting screw rod 2324 is adjusted to a suitable position, in order to prevent its accidental rotation from affecting the fixing effect, the staff can pass the second positioning threaded hole 2328 on the second anti-rotation limiting plate 2327 through a bolt to connect with the corresponding second limiting hole 2329. In this way, the adjusting screw rod 2324 is fixed at the current position to ensure the stability and reliability of the sliding support rod 2325.

[0049] The conical anti-slip surface 2321 of the limiting contact head 232 can increase the contact friction with the hole of the reel 1, so that when the limiting contact head 232 rotates, it can effectively drive the reel 1 to rotate synchronously.

[0050] See also Figure 1 , Figure 8 and Fig. 9 As shown, the adaptive feeding device 3 includes a bidirectionally adjustable screw slide 31 arranged next to the multi-specification winding device 2, a linear conveyor 32 is installed on the movable end of the bidirectionally adjustable screw slide 31, an interval conveyor belt 33 is installed on the linear conveyor 32, a first infrared sensor is installed on the linear conveyor 32, and the adaptive feeding device 3 also includes a mobile placement device 34 arranged below the multi-specification winding device 2.

[0051] The bidirectional adjustment screw slide 31 can accurately adjust the width of the linear conveyor 32. The adjustment function allows the linear conveyor 32 to adapt to reels 1 of different lengths. The linear conveyor 32 is equipped with an interval conveyor belt 33. The design of the interval conveyor belt 33 ensures that the reels 1 can maintain a certain distance during the conveying process to avoid collision or stacking. It is crucial for the subsequent mobile placement device 34 to accurately grasp the reel 1 because it allows each reel 1 to have an independent operating space. The first infrared sensor installed on the linear conveyor 32 is used to monitor the position of the reel 1 in real time. When the reel 1 is placed on the conveyor belt and moves to the sensor detection area, the sensor will immediately sense the presence of the reel 1 and transmit this signal to the control system. A mobile placement device 34 is provided below the multi-specification winding device 2, which is responsible for accurately placing the reel 1 on the linear conveyor 32 into the designated area of ​​the multi-specification winding device 2. When the first infrared sensor detects that the reel 1 has reached the preset position, the mobile placement device 34 will start quickly, grab the reel 1 from the conveyor belt, and steadily place it in the clamping mechanism of the multi-specification winding device 2. At this time, the limit pressing device 23 will immediately limit and resist the reel 1 to ensure that it remains stable during the winding process, thus achieving efficient and accurate feeding of reels 1 of different sizes.

[0052] See also Figure 8 and Fig. 9 As shown, the mobile placement device 34 includes a fixed mounting frame 341, a rotating bracket 342 is installed on the fixed mounting frame 341, a first rotating driver 343 is installed on the side of the fixed mounting frame 341, the output end of the first rotating driver 343 is transmission-connected to the rotating bracket 342, a limiting clamping frame 345 is also installed on the rotating bracket 342, the limiting clamping frame 345 is provided with a material receiving groove 3451, and a second linear driver 344 is also installed on the rotating bracket 342, and the output end of the second linear driver 344 is transmission-connected to the limiting clamping frame 345.

[0053] A first rotary driver 343 is installed on the side of the fixed mounting frame 341, and its output end is connected to the rotating bracket 342. When the placement position or direction of the reel 1 needs to be adjusted, the control system sends a command to the first rotary driver 343, and the first driver drives the rotating bracket 342 to rotate to a specified angle, thereby ensuring that the limit clamping frame 345 can accurately align with the reel 1 or the multi-specification winding device 2 on the linear conveyor 32. The limit clamping frame 345 is installed on the rotating bracket 342, and a material receiving groove 3451 is provided on the limit clamping frame 345. The shape and size of the material receiving groove 3451 are carefully designed to ensure that the reel 1 can be stably carried. When the rotating bracket 342 rotates to the correct position, the limit clamping frame 345 will drop to an appropriate height, and the material receiving groove 3451 will align with the reel 1 on the linear conveyor 32, ready for grabbing. A second linear driver 344 is also installed on the rotating bracket 342. When the first infrared sensor detects that the roll 1 has reached the preset position, the control system will start the second linear drive 344. The drive pushes the limit clamping frame 345 to move forward so that the receiving slot 3451 fits tightly against the roll 1. After completing the grabbing of the roll 1, the first rotary drive 343 starts again, driving the rotating bracket 342 and the limit clamping frame 345 to rotate to the multi-specification winding device 2. The multi-specification winding device 2 fixes the roll 1. After completing the placement of the roll 1, the mobile placement device 34 will perform a reset operation. The first rotary drive 343 drives the rotating bracket 342 to rotate back to the initial position, and the second linear drive 344 pushes the limit clamping frame 345 back to the starting height, preparing for the next grabbing and placement operation. During the entire process, the control system will monitor the movement status of each component in real time, and adjust and optimize as needed to ensure the smooth progress of the entire loading process.

[0054] See also Fig. 9 and Fig.10 As shown, an inclined guide surface is provided above the guide rail 4, a telescopic guide rod 41 is installed on the guide rail 4, a third linear drive 42 is installed at the material receiving end of the inclined guide surface, and the output end of the third linear drive 42 is transmission-connected to the telescopic guide rod 41.

[0055] An inclined guide surface is provided above the guide rail 4, and the inclined guide surface is inclined at a certain angle to facilitate the roll 1 to slide down by its own gravity. Telescopic guide rods 41 are installed on the guide rail 4, and the length and position of these guide rods can be adjusted as needed. A third linear drive 42 is installed at the material receiving end of the inclined guide surface, and the third linear drive 42 is transmission-connected with the telescopic guide rod 41. When the multi-specification winding device 2 needs to unload the wound roll 1, the third linear drive 42 will start and push the telescopic guide rod 41 to extend below the roll 1. This action ensures that the roll 1 can smoothly move along the telescopic guide rod 41 to the guide rail 4 after being released. Subsequently, the multi-specification winding device 2 releases the fixation of the roll 1, and the wound roll 1 naturally slides down to the area to be processed along the inclined guide surface and the telescopic guide rod 41.

[0056] See also Fig. 9 and Fig.10 As shown, the film roll tail bonding device 43 includes a limit blocking block 432 installed on the guide feed rail 4, the limit blocking block 432 is slidably connected to the guide feed rail 4, a plurality of driving wheels 433 are installed on the guide feed rail 4, an adsorption spraying rail 435 is installed below the driving wheel 433, a visual detector 436 is installed on the adsorption spraying rail 435, an adsorption pipe is installed on one side of the adsorption spraying rail 435, a spraying pipe is provided on the side of the spraying rail 435 away from the adsorption pipe, a second infrared sensor is also installed inside the spraying rail 435, a fixed bracket 437 is installed on the side of the guide feed rail 4, and a rotating pressing plate 438 is installed on the fixed bracket 437.

[0057] The telescopic movement of the limit blocking block 432 is controlled by the fourth linear drive 431. Initially, the limit blocking block 432 is in a retracted state, allowing the roll 1 to move freely on the guide unloading rail 4. The driving wheel 433 is installed on the guide unloading rail 4, and its rotation is controlled by the second rotary drive 434. Initially, the driving wheel 433 is in a stationary state. The visual detector 436 is installed on the adsorption spraying rail 435 for real-time monitoring of the position of the tail of the film. The adsorption spraying rail 435 includes an adsorption pipe and a spraying pipe, which are used for adsorption and spraying adhesives, respectively. The second infrared sensor is installed inside the spraying rail 435 for accurately detecting the position of the tail of the film. The rotating pressing plate 438 is installed on the fixed bracket 437, and its rotation is controlled by the third rotary drive 439 to adjust the position and press the tail of the film.

[0058] When the reel 1 moves on the guide rail 4, the control system starts the fourth linear drive 431, so that the limit block 432 extends to prevent the reel 1 from moving further, ensuring that the reel 1 stays above the drive wheel 433. Subsequently, the second rotary drive 434 is started to make the drive wheel 433 rotate forward, driving the reel 1 to rotate. The rotation of the reel 1 will adjust the position of the tail of the wound film so that it gradually approaches the adsorption spraying rail 435. The visual detector 436 monitors the position of the tail of the film in real time. When it is detected that the tail of the film moves to the specified position, the control system issues an instruction to make the drive wheel 433 rotate in the opposite direction, and the reel 1 rotates in the opposite direction accordingly, extending the tail of the film downward into the adsorption spraying rail 435. After the second infrared sensor detects that the tail of the film enters the adsorption spraying rail 435, it immediately starts the adsorption pipeline, and the tail of the film is adsorbed and positioned through the adsorption pipeline to ensure that it remains stable during the spraying process. After the adsorption pipeline is started, the spraying pipeline immediately sprays adhesive to the tail of the film. After the spraying is completed, the adsorption pipeline and the spraying pipeline stop working, and the driving wheel 433 starts again, driving the reel 1 to rotate forward so that the tail of the film can be reeled. At the same time, the third rotary driver 439 controls the rotating pressing plate 438 to rotate and adjust its position so that it conflicts with the outer wall of the wound film. The rotating pressing plate 438 applies appropriate pressure to the tail of the film to ensure that the tail of the glue-coated film fits tightly to the outer wall of the film roll to achieve a winding effect with neat edges. After the tail of the film is fitted, the various components are reset, the limit blocking block 432 is retracted, the driving wheel 433 stops rotating, and the rotating pressing plate 438 is adjusted back to the initial position. Prepare for the next reel 1 processing and film tail fitting operation to ensure the continuity and efficiency of the entire winding process.
