Description

Technical Field

[0001] This utility model relates to the field of film winding technology, specifically to a fully automatic winding machine. Background Technology

[0002] A blown film machine is a device used to produce plastic film. The film produced by the blown film machine needs to be wound up by a winding machine. However, traditional winding machines can only wind up the film. If other processes are to be performed, the formed film needs to be placed in other devices or machines, which is inconvenient.

[0003] Chinese utility model patent publication number "CN213622524U" discloses a film automatic correction constant tension four-station winding device, including a frame and a control system. The frame is arranged from top to bottom with a correction structure, a cutting structure and a winding structure. The winding structure includes a left unfolding roller, a right unfolding roller and constant tension winding devices. There are two constant tension winding devices, left and right, which respectively process the film conveyed by the left unfolding roller and the right unfolding roller, and simultaneously wind up the two sets of films.

[0004] First, the winding device can only wind up the film blown out by the blown film machine. If the film needs to be slit or cut, the rolled film needs to be placed at the slit or cut device and then rewound by the rewinding device, which is a rather cumbersome production process.

[0005] Second, the correction device uses a correction cylinder to push the correction bracket to rotate around the shaft. During rotation, there is no support structure at the edge of the correction bracket. During the correction process, the correction bracket is prone to vibration or shaking, causing secondary deflection of the film, resulting in poor edge correction stability and reliability.

[0006] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0007] The purpose of this invention is to provide a fully automatic winding machine that can cut films according to customer needs and prevents the films from folding during winding, thereby solving the above-mentioned problems existing in the prior art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a fully automatic winding machine, including a mounting base, with a first winding device and a second winding device arranged opposite to each other at both ends of the mounting base, and the first winding device and the second winding device being linked with an inlet device, characterized in that: the inlet device includes a mounting frame disposed on the mounting base, the mounting frame being provided with an input component for inletting film, an output component for transferring film into the first winding device and the second winding device, and a slitting component for slitting film being linked between the mounting frame and the input component and the output component.

[0009] By adopting the above technical solution: the film tube blown out by the blown film machine is cut into two sets of films by the edge-cutting device. The infeeding device can input the two sets of films into the first winding device and the second winding device respectively for bilateral synchronous winding. Alternatively, the two sets of films can be directly guided to one of the winding devices for winding. When it is necessary to cut the film, the cutting component cuts the film that has passed through the input component and the output component, thereby directly cutting the film blown out by the blown film machine during winding, omitting the subsequent cutting process and improving the convenience of production.

[0010] The aforementioned fully automatic winding machine can be further configured as follows: the input component includes a first input roller and a second input roller rotatably connected to the mounting frame; the slitting component includes a slitting rod rotatably connected to the mounting frame; the slitting rod is provided with a plurality of slitting blocks; the slitting blocks are provided with locking holes for fixing the slitting blocks; one end of the slitting block is slidably engaged with the slitting rod; and the other end is provided with a slitting blade.

[0011] By adopting the above technical solution: the film is transferred to the mounting frame through the first input roller and the second input roller. At the same time, the part of the film between the first input roller and the second input roller is kept in a taut state. When the film needs to be cut, the distance between the cutting blocks and the cutting rod is adjusted to the specified cutting width and fixed by the locking hole. Then the cutting rod is rotated so that the cutting blocks on the cutting rod drive the cutting blades to contact the taut film, thereby cutting the film. The cut film can be output to the first winding device and the second winding device respectively through the output component, or it can be directly output to the first winding device or the second winding device for unified winding.

[0012] The aforementioned fully automatic winding machine can be further configured as follows: the output component includes a first output roller and a second output roller. The first output roller is rotatably connected to the mounting frame. An output motor is provided on the mounting frame. An output gearbox is linked to the output end of the output motor. The first output roller is linked to the output gearbox. Output slide plates are provided on both sides of the mounting frame. Output sliding parts are rotatably connected to both ends of the second output roller. The output sliding parts slide in cooperation with the output slide plates. An output cylinder is provided on the mounting frame. The output sliding parts are linked to the output end of the output cylinder.

[0013] By adopting the above technical solution: the film introduced by the input component is output through the output component. The output cylinder operates to make the output slider slide relative to the output slide plate, thereby adjusting the distance between the second output roller and the first output roller, so that the film can pass between the first output roller and the second output roller. During the film output process, the output motor operates to drive the first output roller to rotate stably through the output gearbox. The first output roller can continuously pull the film to maintain the stable output of the film. At the same time, when the film output becomes loose, the output cylinder can also drive the second output roller to re-tension the film and prevent the film from deflecting.

[0014] The aforementioned fully automatic winding machine can be further configured as follows: the output component is linked to a waste output component, the waste output component includes a mounting plate and several connecting rods on the mounting plate, the mounting plate has several mounting slots, one end of the connecting rod is slidably engaged with the mounting slot, and the other end is provided with a waste edge guide wheel, the waste edge guide wheel is used to discharge and collect waste.

[0015] By adopting the above technical solution: waste edges are generated during film slitting. The waste edges can be output to the waste edge collection device through the waste output component. When the waste edges are output, they pass through the middle of the waste edge guide wheel. When the waste edges move, the waste edge guide wheel rotates relative to the connecting rod to support and guide the waste edges. In addition, the connecting rod can slide in the mounting groove to adjust the tension of the waste edges and improve the stability of waste edge output.

[0016] The aforementioned fully automatic winding machine can be further configured as follows: an edge-correcting device is provided above the mounting frame. The edge-correcting device includes an edge-correcting frame and an edge-correcting seat mounted on the edge-correcting frame. The edge-correcting seat is linked to an edge-correcting bracket. The edge-correcting bracket is provided with a first traction roller shaft and a first flattening roller shaft. An edge-correcting electric cylinder is provided at one end of the edge-correcting seat along the film conveying direction, and a rotating component is provided at the other end. One end of the rotating component is rotatably connected to the edge-correcting seat, and the other end is rotatably connected to the edge-correcting bracket. The edge-correcting bracket is linked to the output end of the edge-correcting electric cylinder. The operation of the edge-correcting electric cylinder drives the edge-correcting bracket to rotate around the axial direction of the rotating component. Several edge-correcting support plates are provided below the edge-correcting bracket. An edge-correcting wheel is linked on the edge-correcting support plate. An edge-correcting block is provided on the edge-correcting seat and linked to the edge-correcting wheel. An edge-correcting groove is provided on the edge-correcting block. The edge-correcting wheel slides in cooperation with the edge-correcting groove. A second flattening roller shaft and a second traction roller shaft are also provided on the edge-correcting frame.

[0017] By adopting the above technical solution: the film can be edge-corrected by the edge-correcting device. The film is guided to the input component by the first traction roller, the first flattening roller, the second flattening roller, and the second traction roller. The first flattening roller and the second flattening roller have a certain curvature, which can flatten the film and maintain its unfolded state. When the film is about to bend, the edge-correcting electric cylinder drives the edge-correcting bracket to rotate relative to the edge-correcting seat around the rotating part, and re-tensions the film that is about to bend. At the same time, the edge-correcting wheel slides in the edge-correcting groove of the edge-correcting block, which improves the stability of the rotation of the edge-correcting bracket. Furthermore, the edge-correcting block is inclined relative to the edge-correcting seat, and the inclination of the edge-correcting blocks at both ends along the film transport direction is different, which can guide the rotation of the edge-correcting bracket and maintain the consistency of the edge-correcting bracket during rotation.

[0018] The aforementioned fully automatic winding machine can be further configured such that: a cutting assembly is also provided on the mounting frame, the cutting assembly includes a cutting rodless cylinder on the mounting frame, a set of cutting blade seats is provided at both ends of the cutting rodless cylinder, the cutting blade seats are slidably engaged with the cutting rodless cylinder, a cutting blade plate is installed on the cutting blade seat, and the cutting rodless cylinder drives the cutting blade seats to move and adjust the distance between the cutting blade seats.

[0019] By adopting the above technical solution: when the user needs to cut to a fixed width, the cutting blade assembly is separated from the film, and the cutting rodless cylinder adjusts the distance between the two cutting blade holders to the specified width. Then, the film is cut to the specified width by the cutting blade plate and is wound up by the first winding device and the second device. At the same time, the waste edge is output through the waste edge output component. This allows for direct fixed-width cutting of the film when winding the film blown out of the blown film machine, which simplifies the film cutting operation and improves production efficiency.

[0020] The aforementioned fully automatic winding machine can be further configured as follows: the first winding device includes a winding frame, on which a roller, a shaft unloading assembly, a flying knife assembly, and a shaft release assembly are mounted. The roller is rotatably connected to the winding frame. The winding frame is equipped with a roller motor for driving the roller to rotate. The output end of the roller motor is linked to a roller gearbox. The roller and the roller gearbox are linked. Transfer plates are provided on both sides of the roller. The transfer plates have transfer slots. Tensioning rollers are also provided on the transfer plates. Transfer gear rings are linked to the transfer plates. The winding frame is also equipped with a drive rod. A drive gear ring is provided on the drive rod. The transfer gear ring is linked through a synchronous toothed belt or rack. The winding frame is also equipped with a transfer motor. The output end of the transfer motor is linked to a transfer gearbox. The drive rod and the transfer gearbox are linked. The operation of the transfer motor causes the drive rod to rotate, driving the transfer plate to rotate circumferentially around the central axis of the roller. The winding frame is also equipped with a third flattening roller for flattening the film. The second winding device has the same structure as the first winding device.

[0021] By adopting the above technical solution: the film can remain in an open state after passing through the third flattening roller, resulting in more uniform film winding. The winding roller is placed on the unloading assembly during winding, and the roller motor drives the roller to rotate, winding the film onto the winding roller to achieve the film winding operation. At the same time, a spare winding roller is provided on the unloading assembly. After winding is completed, the transfer motor works to transmit torque to the drive rod through the transfer reduction gearbox, driving the drive rod to rotate. The drive gear ring on the drive rod drives the transfer gear rings at both ends of the roller to rotate synchronously, thereby causing the transfer plates at both ends of the roller to rotate. The transfer plate drives the tension roller to rotate synchronously around the central axis of the roller to tension the film. Then, the flying knife assembly cuts the film, and the unloading assembly puts the spare take-up roller into the transfer slot of the transfer plate. The tension roller wraps the cut film around the spare take-up roller. The unloading assembly unloads the taken-up roller. Then, the transfer plate rotates in the opposite direction to transfer the spare take-up roller to the unloading assembly, realizing continuous film winding. In addition, the second winding device has a similar structure to the first winding device and can also realize continuous film winding, improving the film winding efficiency.

[0022] The aforementioned fully automatic winding machine can be further configured as follows: the unwinding assembly includes unwinding plates located on both sides of the winding frame, the middle of the unwinding plate is hinged to the winding frame, one end of the unwinding plate is provided with an unwinding cylinder and the other end is provided with an unwinding slot, the body of the unwinding cylinder is hinged to the winding frame, the output end of the unwinding cylinder is hinged to the unwinding plate, the unwinding plate is also linked to a pushing cylinder, the output end of the pushing cylinder is provided with a pushing plate, the operation of the pushing cylinder drives the pushing plate to move and causes the winding roller shaft in the unwinding slot to move.

[0023] By adopting the above technical solution: the spare take-up roller is placed in the unwinding slot. After the take-up roller completes its winding, the transfer plate rotates the transfer slot to below the unwinding plate. Then, the unwinding cylinder rotates to push the unwinding plate to rotate, bringing the unwinding slot closer to the transfer slot. Subsequently, the pusher cylinder drives the pusher plate to move, pushing the spare take-up roller from the unwinding slot to the transfer slot, thereby realizing automatic switching of the take-up roller and improving the continuity of winding.

[0024] The aforementioned fully automatic winding machine can be further configured as follows: the flying knife assembly includes flying knife holders located on both sides of the winding frame, the flying knife holders are equipped with flying knife rodless cylinders, flying knife seats are slidably fitted on the flying knife rodless cylinders, the flying knife seats are equipped with blade plates, and the blade plates have knife grooves for cutting the film.

[0025] By adopting the above technical solution: after the tensioning roller tensions the film, the fly knife rodless cylinder can drive the fly knife holder to slide quickly, so that the film passes through the knife groove on the knife plate and cuts the film quickly, ensuring the cutting quality. After cutting, the fly knife holder can be quickly reset, which is convenient for the next cutting operation.

[0026] The aforementioned fully automatic winding machine can be further configured as follows: the unloading assembly includes a take-up mandrel and an unloading mandrel disposed within the winding frame. Take-up arms are installed at both ends of the take-up mandrel. The upper end of the take-up arm is provided with a take-up slot for placing the winding roller shaft. A take-up cylinder is installed on the take-up arm to drive it to rotate around the take-up mandrel. Unloading arms are installed at both ends of the unloading mandrel. The upper end of the unloading arm is provided with an unloading slot for placing the winding roller shaft. An unloading cylinder is installed on the unloading arm to drive it to rotate around the unloading mandrel.

[0027] By adopting the above technical solution: the take-up roller is placed in the take-up bay of the take-up arm during take-up. After the take-up roller completes the winding and forming, the take-up cylinder pushes the take-up arm to rotate towards the discharge arm, transferring the take-up roller from the take-up bay to the discharge bay of the discharge arm. Then, the discharge cylinder pushes the discharge arm to rotate, completing the automatic discharge of the film roll, improving production efficiency. After the take-up arm completes the transfer of the take-up roller, it rotates towards the roller direction. At this time, the spare take-up roller is placed in the transfer bay from the release bay. Then, the transfer plate places the spare take-up roller in the take-up bay for continuous winding operation. At the same time, the next take-up roller is placed in the release bay, which facilitates the switching operation of the next take-up roller.

The edge-correcting frame 51 is also provided with a second flattening roller shaft 511 and a second traction roller shaft 512. When the film is deflected during winding, the edge-correcting electric cylinder 521 drives the edge-correcting bracket 53 to rotate around the rotating part 522 toward the side of the film deflection, so that the film is restored to a taut state.

[0055] The working principle of the fully automatic winding machine in this embodiment is as follows:

[0056] The film blown out by the blown film machine passes through the first traction roller 531 and the first flattening roller 532 on the edge straightening bracket 53, and then passes through the second flattening roller 511 and the second traction roller 512 to be transported into the inlet device 4.

[0057] The film is then kept taut by the first input roller 421 and the second input roller 422. The slitting blade 444 then cuts the film. The cut film is output from the first output roller 431 and the second output roller 432 to the first winding device 2 and the second winding device 3. At the same time, the waste edge of the film is output to the waste edge collection device through the waste edge guide wheel 454.

[0058] Then the film rotates around the take-up roller shaft located in the take-up slot 233 of the take-up arm 232. The take-up roller shaft is in contact with the roller 22 for winding. When the take-up roller shaft has finished winding, the transfer plate 26 rotates around the central axis of the roller 22, and rotates the transfer slot 261 to below the release slot 253 of the release plate 251. The push cylinder 254 pushes the push plate 255 to move and put the spare take-up roller shaft into the transfer slot 261 of the transfer plate 26.

[0059] At this time, the tensioning roller 262 tensions the film, and the flying knife rodless cylinder 242 drives the flying knife holder 243 to move along the axis of the flying knife rodless cylinder 242. The film is cut by passing through the knife groove 245 on the knife plate 244. The cut film is wound on the spare take-up roller. At the same time, the take-up cylinder 234 pushes the take-up arm 232 to rotate around the take-up shaft core 231, and the completed take-up roller falls into the unloading bay 237 of the unloading arm 236. The take-up arm 232 returns to its original position, and the unloading arm 236 drives the completed take-up roller to swing until it contacts the ground. The worker takes away the take-up roller. After the take-up arm 232 returns to its original position, the transfer plate 26 drives the spare take-up roller to rotate into the take-up bay 233 of the take-up arm 232. The spare take-up roller continues to be wound, realizing roll changing and unloading without stopping the machine.

[0060] It should be noted that the fully automatic winding machine in this embodiment does not need to cut the film. The formed film is directly transferred to the first winding device 2 and the second winding device 3 through the edge straightening device 5 and the guide device 4 to maintain stable winding of the film. In addition, only the first winding device 2 or the second winding device 3 can be operated to realize the winding operation of the film by one winding device.

[0061] The working principle of the edge-correcting device 5 in this embodiment is as follows:

[0062] When the film passes through the edge-correcting device 5, it comes into contact with the outer surfaces of the first traction roller 531, the first flattening roller 532, the second flattening roller 511, and the second traction roller 512. When no deviation occurs, the first flattening roller 532 and the second flattening roller 511 have a certain curvature in the middle, which flattens and flattens the film on both sides, effectively preventing the film from deflecting. When the film deflects, the edge-correcting electric cylinder 521 operates, driving the edge-correcting bracket 53 to rotate around the rotating component 522. At the same time, the edge-correcting wheel 534 slides in the edge-correcting groove 524 of the edge-correcting block 523. The first traction roller 531 and the first flattening roller 532 rotate synchronously with the edge-correcting bracket 53, re-tensioning and flattening the deflected film, thus completing the edge correction of the film. Example 2:

[0063] like Figure 1 , Figure 2 The fully automatic winding machine shown differs from Embodiment 1 in that the mounting frame 41 is further provided with a cutting assembly 46. The cutting assembly 46 includes a cutting rodless cylinder 461 mounted on the mounting frame 41. Both ends of the cutting rodless cylinder 461 are provided with a set of cutting blade seats 462. The cutting blade seats 462 are slidably engaged with the cutting rodless cylinder 461. A cutting blade plate 463 is mounted on the cutting blade seat 462. The cutting rodless cylinder 461 drives the cutting blade seats 462 to move and adjust the spacing between the cutting blade seats 462.

[0064] The working principle of this embodiment is as follows: when the film does not need to be slit but needs to be cut to a fixed width, the excess part of the film is cut off by the cutting blade 463, and the waste edge is output to the waste collection device through the waste output component 45. The cut film is then transported to the first winding device 2 and the second winding device 3 to complete the automatic winding of the film. The winding working principle of the first winding device 2 and the second winding device 3 is the same as the winding principle in Embodiment 1.

[0065] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
