Technical Field

[0001] This utility model relates to the technical field of coreless winding film machines, specifically a high-efficiency protective coreless winding film machine. Background Technology

[0002] Coreless winding film machine is a device specifically designed to wind plastic film into rolls without using traditional rigid paper tubes or plastic tubes as inner cores during the winding process.

[0003] For example, patent application number 202220313574.4 published on the China Patent Network, entitled "Automatic Control Anti-deviation Correction Mechanism for Tube Rolling Machine," includes a mounting plate with side plates on one side of the mounting plate. A guide groove is formed at the lower end of each side plate, and a limiting block is located within the guide groove. A shaft is positioned between the two limiting blocks, and a support structure is mounted on the shaft. The lower side of each limiting block, away from the shaft, is fixedly connected to a first hydraulic cylinder. A motor is fixedly mounted on the upper side of the side plate, and the motor's rotation shaft passes through the side plate and is fixedly connected to a guide roller shaft.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, the present invention provides a high-efficiency protective coreless winding film machine, which includes a machine body 1;

[0028] The machine body 1 has an internal transmission connection to a take-up roller 2. Both sides of the machine body 1 are movably connected to a swing arm 3 via a pin. The side of the swing arm 3 away from the machine body 1 extends to the top of the machine body 1. The side of the swing arm 3 away from the machine body 1 is fixedly connected to a shield 4 located on the top of the machine body 1. A transmission structure is provided on the back of the machine body 1, which can control the opening and closing of the shield 4.

[0029] refer to Figure 3 The transmission structure includes a vertical plate 5 fixedly connected to the back of the body 1, a transmission motor 6 fixedly connected to the surface of the vertical plate 5, a screw 7 fixedly connected to the output end of the transmission motor 6, a screw sleeve 8 threadedly connected to the surface of the screw 7, a sleeve plate 9 located outside the screw sleeve 8 fixedly connected to the side of the swing arm 3 near the body 1, a connecting block 10 located outside the sleeve plate 9 fixedly connected to the top of the screw sleeve 8, a sliding rod 11 located inside the sleeve plate 9 fixedly connected to the surface of the connecting block 10, and the sliding rod 11 slidably connected to the sleeve plate 9.

[0030] As a technical optimization of this utility model, the sliding connection between the slide rod 11 and the sleeve plate 9 provides a stable and reliable force transmission path, ensuring stable transmission and smooth and controllable movement of the swing rod 3 and the shield 4.

[0031] refer to Figure 2 Both ends of the take-up roller 2 pass through the machine body 1 and extend to the outside of the machine body 1. A bracket 12 is fixedly connected to one side of the machine body 1. A drive motor 13 is fixedly connected to the surface of the bracket 12. The output end of the drive motor 13 passes through the bracket 12 and is connected to the take-up roller 2.

[0032] As a technical optimization of this utility model, by using a standardized drive motor 13 and fixing it to one side of the body 1 with a bracket 12, installation and maintenance are convenient and power transmission is direct.

[0033] refer to Figure 3 The surface of the take-up roller 2 is fixedly connected to a ratchet 14 located on the outside of the machine body 1, and the surface of the screw sleeve 8 is provided with a braking structure, which can brake and stop the take-up roller 2 when the screw sleeve 8 moves forward.

[0034] As a technical optimization of this utility model, by introducing a linkage mechanical braking function, not only is physical isolation provided, but the source of danger is also forcibly stopped, thus completely eliminating the risk of rotational injury.

[0035] refer to Figure 3 The braking structure includes an extension rod 15 fixedly connected to the inner end of the slide rod 11. A pawl assembly 16 is fixedly connected to the end of the extension rod 15 away from the slide rod 11. The side of the pawl assembly 16 away from the extension rod 15 can extend into the interior of the ratchet 14 and mesh with the ratchet 14 when the screw sleeve 8 moves forward.

[0036] As a technical optimization of this utility model, the inner end of the slide rod 11 is connected to the extension rod 15, and the extension rod 15 is connected to the pawl assembly 16, forming a clear and almost lossless power transmission chain. The movement of the screw sleeve 8 directly drives the extension rod 15 and the pawl assembly 16 through the slide rod 11.

[0037] refer to Figure 2 A support frame 17 is fixedly connected to the back of the upright plate 5. The support frame 17 is respectively sleeved on the surface of the screw 7 and the screw sleeve 8. The screw sleeve 8 and the support frame 17 are slidably connected. The screw 7 and the support frame 17 are movably connected through bearings.

[0038] As a technical optimization of this utility model, the support frame 17 is fixed to the upright plate 5 and sleeved on the outside of the screw rod 7 and the screw sleeve 8, which plays a precise guiding and stable supporting role for the movement of the screw sleeve 8, preventing the screw sleeve 8 from swaying or vibrating during the movement, and ensuring smooth transmission and accurate positioning.

[0039] The working principle and usage process of this utility model are as follows: During normal operation, the drive motor 13 drives the take-up roller 2 inside the machine body 1 to rotate at high speed through the bracket 12 to wind the film. At this time, the shield 4 is closed for protection. When a stop command is received, the transmission motor 6 starts and drives the screw 7 to rotate, forcing the threaded sleeve 8 connected to it to move in a direction within the support frame 17. The threaded sleeve 8 drives the slide rod 11 to move synchronously through the connecting block 10. The slide rod 11 slides and engages with the sleeve plate 9 fixed on the swing rod 3, pulling the swing rod 3 to swing backward around the pin axis, thereby quickly opening the top shield 4 to expose the winding area for operation. At the same time, the extension rod 15 fixed to the inner end of the slide rod 11 moves with the slide rod 11, pushing the pawl assembly 16 at its end to move forward and accurately engage in the tooth groove of the ratchet 14 at the end of the take-up roller 2, generating forced engagement braking on the take-up roller 2 to keep it stopped and prevent the drive motor 13 from being accidentally opened during operation.

[0040] In summary, this highly efficient protective coreless winding film machine, by setting up a movable shield 4, can completely cover the area of ​​the high-speed rotating take-up roller 2 when needed, forming a reliable physical barrier, effectively preventing the operator's limbs, clothing or tools from being caught in the rotating parts, and significantly reducing the incidence of personal injury accidents.
