Description

Technical Field

[0001] This utility model relates to a coating assembly for a winding machine. Background Technology

[0002] A winding machine is used to coil long strips of sheet material. It uses a sleeve as a hollow carrier. After the sheet is coiled on the sleeve, it protects the flexible sheet and simultaneously binds it to prevent it from unraveling. Current technology involves manually winding the sheet roll with the sleeve inside and outside a film or wrapping it entirely, which is time-consuming, labor-intensive, and prone to causing the coiled sheet to loosen. Other methods involve overall film coating followed by vacuuming, but these require a large amount of additional equipment and power, and also necessitate process turnover.

[0003] How to provide an automated coating assembly that prevents the outer surface of the coiled sheet from being scratched, avoids loosening of the coil, and reduces the number of process turnovers has become an urgent technical problem to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is, in general, to provide a coating assembly for a winding machine.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] To achieve automatic film coating and wrapping of coiled sheet rolls, a film coating assembly for a winding machine includes a movable film coating frame; a secondary movable frame moves on the film coating frame.

[0007] A film-coating spindle is rotatably mounted on a secondary moving frame;

[0008] A coating roll is mounted on the coating spindle;

[0009] A film-cutting cutter is installed on one side of the film-coating roll on the film-coating mobile frame.

[0010] As a further improvement to the above technical solution:

[0011] To ensure that normal winding operations are not obstructed, the film-coating moving frame is positioned close to or far from the winding spindle.

[0012] To enable lamination and cutting, the lamination cutter is located below the lamination roll.

[0013] A laminating pressure roller is installed below the laminating cutter;

[0014] The coated roller is used to make rolling contact with the outermost sheet surface on the main shaft of the coil.

[0015] The blade of the laminating cutter is serrated.

[0016] In order to achieve continuous and uniform output of the coating, a coating guide roller frame is provided on one side of the coating roll on the coating moving frame.

[0017] A first coating guide roller and a second coating guide roller are arranged vertically on the coating guide roller frame;

[0018] During the lamination process, the second lamination guide roller and the lamination pressure roller press the lamination film onto the outermost surface of the sheet wound on the main winding shaft.

[0019] When cutting the film, the secondary moving frame drives the second guide roller of the film coating away from the main shaft of the winding, so that the film output from the second guide roller of the film coating contacts the film coating cutter and is disconnected.

[0020] In order to achieve timely braking of the film-coated roll, a brake push rod located on one side of the film-coating main shaft is installed on the secondary moving frame;

[0021] The brake push rod is used to contact and brake the coating spindle.

[0022] To achieve a damping effect, there are long grooves on the film-coating moving frame; the two ends of the first film-coating guide roller are set in the corresponding long grooves.

[0023] In order to center and fix the coated roll, two opposing positioning sleeves are provided on the coating spindle for mounting the two ends of the inner hole of the coated roll.

[0024] A back nut is provided at the suspended end of the coating spindle, which is threaded to the coating spindle, and the back nut abuts against a positioning sleeve.

[0025] To achieve the side guard, the positioning sleeve has a positioning step for the side guard.

[0026] To achieve power drive, a secondary push rod for driving the secondary moving frame is installed on the film-coating mobile frame;

[0027] Parallel film-coating moving push rods and film-coating main guide rails are connected to the film-coating moving frame.

[0028] This invention enables automated film coating, maintaining film flatness and preventing skewing. It allows for automatic continuous cutting without affecting subsequent processes, and utilizes double rolling for superior coating results. This invention is rationally designed, low-cost, robust, durable, safe, reliable, easy to operate, time-saving, labor-saving, cost-effective, compact, and convenient to use.

Detailed Implementation

[0034] like Figure 1-4 As shown, the film coating assembly for the winding machine in this embodiment includes a movably disposed film coating moving frame 304, which is movably disposed on the winding machine frame; a secondary moving frame 308 moves on the film coating moving frame 304, thereby creating a relative misalignment to achieve film cutting;

[0035] A film-coating spindle 316 is rotatably mounted on the secondary moving frame 308, which serves as a support for the film-coated roll.

[0036] A coating roll 301 is mounted on the coating spindle 316;

[0037] A film-coating cutter 302 is provided on one side of the film-coating roll 301 on the film-coating moving frame 304;

[0038] The film-coating moving frame 304 is positioned close to or away from the main winding shaft 402; when film coating is performed after winding is completed, the film-coating moving frame 304 is close to the main winding shaft 402, otherwise, it is away from the main winding shaft 402.

[0039] The laminating cutter 302 is located below the laminating roll 301, which facilitates the laminating roll to hang down by its own weight and makes it easy to cut the laminating roll.

[0040] A film-coating pressure roller 303 is provided below the film-coating cutter 302;

[0041] The film-coated roller 303 is used to make rolling contact with the outermost sheet surface on the winding spindle 402.

[0042] To prevent the film from sticking together and to achieve a tearing and cutting effect, the blade of the film-coating cutter 302 is serrated.

[0043] A film-coating guide roller frame 305 is provided on one side of the film-coating roll 301 on the film-coating moving frame 304;

[0044] The first guide roller 306 and the second guide roller 307 for film coating are arranged on the upper and lower parts of the film coating guide roller frame 305, so as to realize the upper and lower roller pressure of the output film coating, which ensures that the film coating is in an open and flat state, and also ensures that the film coating speed is stable and prevents backflow.

[0045] During the lamination process, the second lamination guide roller 307 and the lamination pressure roller 303 press the lamination film onto the outermost surface of the coiled sheet on the main winding shaft 402; the lamination cutter 302 is spaced apart from the lamination film to avoid interference with normal lamination.

[0046] After lamination is completed, the film needs to be cut. Traditional cutting methods often result in misaligned cuts, producing thin, slanted strips that prevent further lamination. To address this, during film cutting, the secondary moving frame 308 moves the second lamination guide roller 307 away from the main winding shaft 402. This ensures that the film output from the second lamination guide roller 307 contacts and breaks off from the lamination cutter 302, guaranteeing a clean, straight cut that does not interfere with subsequent lamination work.

[0047] To ensure speed matching between the coating and the winding spindle 402 and reduce power output, the coating spindle 316 is designed as a passive, unpowered output.

[0048] To prevent the coated roll 301 from accelerating and rolling under inertia, a brake push rod 309 is provided on the secondary moving frame 308 on one side of the coating spindle 316; the brake push rod 309 is used to contact and brake the coating spindle 316.

[0049] The film-coating moving frame 304 has a long groove 310; the two ends of the film-coating first guide roller 306 are set in the corresponding long groove 310, so that the film-coating first guide roller 306 can press down on the film by gravity, thereby achieving a damping effect.

[0050] Two opposing positioning sleeves 311 are provided on the coating spindle 316 for mounting the two ends of the inner hole of the coating roll 301; thus achieving end support, good processability, and structural stability.

[0051] A back nut 312 is provided at the suspended end of the coating spindle 316, which is threadedly connected to the coating spindle 316. The back nut 312 abuts against a positioning sleeve 311, thereby facilitating disassembly and assembly.

[0052] The positioning sleeve 311 has a positioning step 313 with a side stop, which realizes the lateral positioning of the film-coated roll 301.

[0053] A secondary push rod 315 for driving the secondary moving frame 308 is provided on the film-coating moving frame 304; this enables secondary drive adjustment and cuts the film.

[0054] Parallel film-coating moving push rods 314 and film-coating main guide rails 317 are connected to the film-coating moving frame 304 to guide and drive the film-coating operation.

[0055] As a specific working principle, a film roll 301 is installed on the film coating spindle 316, supported by a positioning sleeve 311, and threadedly fastened to the end of the film coating spindle 316 via a back nut 312. The film end is output through the first film coating guide roller 306 and the second film coating guide roller 307 to the outermost surface of the already coiled sheet on the winding spindle 402. Then, by using the film coating movement push rod 314, the film coating movement frame 304 moves from position D1 to position D2, and both the film coating pressure roller 303 and the second film coating guide roller 307 contact the outermost surface of the sheet through the output film. Furthermore, as the winding spindle 402 rotates, the film is continuously output and... The process begins with winding the film. Next, when cutting is required, the secondary moving frame 308 retracts from position C2 to C1, allowing the film to contact and cut with the film-coating cutter 302. Simultaneously, the film-coating pressure roller 303 continues to roll the film onto the outermost surface of the sheet until all remaining film is coated. The cut end droops at the front end of the second film-coating guide roller 307 and is held in place by the gravity of the first film-coating guide roller 306. Because the film roll 301, the first film-coating guide roller 306, and the second film-coating guide roller 307 move as a whole, the length of the cut film will not change due to the movement of the secondary moving frame 308 or the film-coating moving frame 304, thus facilitating the next film-coating operation. The film-coating spindle 316 is braked by the brake push rod 309 to prevent the influence of inertial force on the film length. The positioning step 313 prevents the coated roll 301 from deviating and achieves precise side positioning. The secondary moving frame 308 is moved by the secondary push rod 315, while the main guide rail 317 provides guidance.
