As shown in fig. 1 to 3, the present embodiment discloses a cutting device of a winding machine, which is provided on the winding machine for cutting a sheet or film.

In order to cut a sheet or film, the cutting device comprises a cutting mechanism 1, wherein the cutting mechanism 1 comprises a cutter 2, a cutter driving assembly 12, a cutter swing seat 13 and a linear guide rail 14. Wherein, cutter 2, cutter drive assembly 12 and linear guide 14 are all fixed in on the sword pendulum seat 13, and linear guide 14 sets up along the lateral direction of sword pendulum seat 13. The cutter 2 is fixed on a cutter holder 15, the cutter holder 15 is in sliding connection with the linear guide rail 14 through a sliding block, and the cutter driving assembly 12 is connected with the cutter holder 15. Preferably, the cutter drive assembly 12 is a cylinder.

When the sheet or film is required to be cut, the cutter 2 is driven by the cutter driving assembly 12 to slide on the linear guide rail 14, and the sheet or film is cut in the process of sliding the cutter 2. Due to the fact that the linear guide rail 14 is arranged on the cutter swing seat 13, the cutter 2 slides along the linear guide rail 14, accurate guiding of the cutter 2 is guaranteed, stability of a cutting process is guaranteed, and deviation of the position of the cutter 2 in a moving process is avoided.

In order to detect the movement of the cutter 2, the present embodiment further includes an initial position sensor 16 and an in-position sensor 17 on the cutter swing seat 13, where the initial position sensor 16 and the in-position sensor 17 are disposed at opposite ends of the linear guide 14, respectively. The position of the cutter 2 is detected by the home position sensor and the in-place sensor 17, and it is ensured that the sheet or film can be cut.

The sheet or film needs to be compressed between cuts, so the cutting device further comprises a compressing mechanism 2, and the compressing mechanism 2 is fixed on the knife swing seat 13. Further, the pressing mechanism 2 comprises a pressing cylinder 21 and a pressing roller 22, the pressing cylinder 21 is connected with the pressing roller 22, and the pressing cylinder 21 drives the pressing roller 22 to stretch out of the pressing sheet or film. Preferably, the number of the pressing cylinders 21 is two, and the two pressing cylinders 21 are respectively arranged at opposite ends of the pressing roller 22. When it is desired to press the sheet or film, the pressing cylinder 21 is extended, and the pressing roller 22 presses the sheet or film, thereby facilitating the cutting of the sheet or film by the cutter 2.

The cutting device is further provided with a guide mechanism 3, the guide mechanism 3 at least comprises a guide seat 31, one end of the guide seat 31 is fixed with a rotating shaft, and the bottom of the knife swinging seat 13 is rotatably hinged with the guide seat 31 through the rotating shaft. The cutting device further comprises an opening and closing component 4, the opening and closing component 4 is connected with the knife swinging seat 13, and the opening and closing component 4 drives the knife swinging seat 13 to rotate relative to the guide seat 31. Preferably, the opening and closing component 4 is an opening and closing cylinder. When the winding machine is in a normal winding state, the opening and closing component 4 stretches out, the cutting mechanism 1 is arranged in a direction away from a winding shaft on the winding machine, and when the winding machine is in a cutting state, the opening and closing component 4 retracts to drive the cutting mechanism 1 to rotationally move in a direction close to the winding shaft.

The guide mechanism 3 further comprises a plurality of guide rollers 32, a guide fixing seat 33 is arranged on the guide seat 31, and two ends of the guide rollers 32 are respectively and rotatably connected with the guide fixing seat 33. A plurality of guide rollers 32 are respectively disposed on the upper surface or the lower surface of the guide holder 31. The sheet or film is guided by the guide roller 32 of the guide mechanism 3 and wound around a take-up shaft. The guide holder 31 is also fixed with a tension sensor 34, and the tension sensor 34 detects tension of the sheet or film passing through the guide roller 32. Ensuring that the tension of the sheet or film is within a defined range ensures that the wound rolls are substantially uniform in tightness and the diameter of the rolls varies less.

Fig. 2 is a schematic diagram of a cutting device of the winding machine in a normal winding state. In the normal winding state, the opening and closing assembly 4 extends out, and turns the cutting mechanism 1 away from the winding shaft. As shown in fig. 3, a schematic view of the winding cut state is shown. When the winding shaft needs to be replaced, the opening and closing assembly 4 retracts to drive the cutting mechanism 1 to move towards the direction approaching the winding shaft. After the opening and closing assembly 4 is retracted, the pressing cylinder 21 is extended, and the pressing roller 22 presses the sheet or film onto the new take-up shaft and is firmly stuck by double-sided adhesive. The cutting drive assembly then drives the cutter 2 to move from one side of the cutter saddle 13 to the other, thereby cutting the sheet or film.

After the sheet or film is cut off, the compression cylinder 21 is retracted, the opening and closing component 4 is extended, the knife swinging seat 13 is restored to the initial state, and meanwhile, the cutting driving component drives the knife 2 to move and also restore to the initial position. The new take-up reel then starts taking up.

The embodiments of the present utility model are not limited thereto, and the present utility model may be modified, substituted or combined in various other forms without departing from the basic technical spirit of the present utility model, which falls within the scope of the claims, according to the above-described aspects of the present utility model, using the general knowledge and conventional means of the art.
