Detailed Description

The utility model will be further described with reference to the drawings and examples.

The terms "first", "second", etc. in the present utility model are used only to distinguish different components. Both "first material" and "second material" are understood to be printing materials acceptable to printing devices, including but not limited to various types of paper, cloth, plastic film, and the like.

Referring to fig. 1, the principle of deviation correction in cutting of the existing cutting machine with film coating function can be seen, the printing material 101 is wound on the first unwinding roller 1, after being unwound by the unwinding roller, the printing material sequentially passes through the fourth roller 4 and the fifth roller 5, wherein the fifth roller can move downwards to drive the first material on the surface to be pressed onto the protective film 102 below for film coating treatment, and the first material coated with the protective film can be continuously sent to the cutting mechanism for cutting. During this time, the first camera 6 captures a pattern on the first material between the fourth roller and the fifth roller, and transmits the captured image to the correction mechanism 7, which adjusts the incidence angle of the cutting mechanism in the cutter. A method for adjusting the cutting angle of the cutting mechanism by shooting an image with a camera is conventional, for example, CN103224160B filed by the applicant discloses a structure of a cutting machine, and precisely cuts a printing material according to a mark image shot with the camera.

However, the present utility model has found that the angle of conveyance of the printing material changes when the fifth roller 5 is pressed down, as in the printing material 101 of fig. 1, the angle changes α when the fifth roller is pressed down, and the angle at which the first camera captures the printing material changes accordingly, and the captured image itself is subject to errors due to the change in angle. The basis of the deviation correcting action of the deviation correcting mechanism is derived from the shot image, and the change of the image angle caused by the angle also influences the deviation correction, so that the accuracy is reduced.

In order to solve the above problems, a cutter according to the present utility model includes:

The first roller and the second roller can locally tension the first material to form a plane for shooting by the camera, the plane cannot deviate in angle in the film pressing process, and the shooting angle of the camera in shooting the plane is always kept constant, so that the deviation correcting effect of the cutting machine is ensured.

The cutter may further comprise a conveyor roller disposed parallel to the second roller for delivering the second material to the cutting mechanism for cutting. The conveying roller conveys the second material to realize different functions of the cutting machine. The conveying roller can be driven by a motor to rotate and convey the material on the surface thereof.

On the basis of the above structure, the first roller is not movable, and the second roller can be provided in two ways, namely, movable (fig. 2 a) and fixed (fig. 2 b): a. the movable second roller can be used for pressing the first material on the surface of the second material, and the cutting can be realized as a printing material film coating and pasting function; b. the fixed second roller needs to be additionally provided with a movable third roller to realize the functions of film covering and pasting. These two cases are each specifically described below.

Example 1: using a movable second roller

Referring to fig. 2a, in the present embodiment, the second roller 202a can move up and down linearly as a roller for coating, and the holding of the photographing angle of the first material 100 tensioned by the first roller 201 and the second roller 202a and the first camera 6 is achieved by the following arrangement: the direction of movement of the second roller 202a coincides with the direction of transfer of the first material 100 between the first roller 201 and the second roller 202 a. The specific cutting machine structure further comprises a moving mechanism for driving the second roller to move linearly to approach the conveying roller, so that the first material conveyed by the second roller is pressed on the second material on the conveying roller, and the transmission direction of the first material between the first roller and the second roller is parallel to the movement direction of the second roller.

One structure of the movement mechanism referring to fig. 3 and 4, the movement mechanism 300 includes a cylinder piston 310, a roller frame 330 and a slide bar mechanism 320, the second roller 202a is rotatably disposed on the roller frame 330, the cylinder piston 310 and the slide bar mechanism 320 are both connected to the roller frame 330, and the cylinder piston 310 drives the roller frame 320 to slide on the slide bar mechanism 320 in the straight line.

The second roller is driven by the moving mechanism to move in a linear motion mode to be close to the conveying roller, meanwhile, the transmission direction of the first material between the first roller and the second roller is matched to be parallel to the linear motion direction, so that the transmission direction of the first material between the first roller and the second roller cannot change in the moving process of the second roller, and the angle of the first material shot by the first camera cannot change.

Example 2: using a fixed second roller

Referring to fig. 2b, in the present embodiment, the third roller 203 is provided as a movable roller, and the relative positions of the first roller 201 and the second roller 202b are fixed, so that the angle at which the first camera 6 photographs the first material 100 can be similarly achieved. The specific cutting machine further comprises:

a third roller 203 disposed between the second roller 202b and the cutting mechanism and parallel to the conveying roller, the first material transferred by the second roller being transferred by the third roller and sent to the cutting mechanism,

Similar to embodiment 1, the movement mechanism comprises a cylinder piston, a roller frame and a slide bar mechanism, the third roller is rotatably arranged on the roller frame, the cylinder piston and the slide bar mechanism are connected with the roller frame, and the cylinder piston drives the roller frame to move on the slide bar mechanism in a straight line.

The first material is pressed on the second material by the third roller, the film covering function can be realized, the movement of the third roller does not influence the conveying direction of the first material at the shooting position, and the shooting angle of the first camera for shooting the first material is ensured to be unchanged.

In both the above embodiments 1 and 2, the angle at which the first camera captures the first material is unchanged, thereby providing an accurate image for subsequent correction.

On the basis of the above embodiment, a guide plate 10 may be further included in the specific cutter structure, and referring to fig. 5a or 5b, the second material 500 may be guided by the guide plate 10 and transferred by the transfer roller 400. And may further include a second unwind roller 9, and the second material 500 may be wound onto the second unwind roller 9 and unwound by the second unwind roller onto the transport roller 400.

When the first material has a back adhesive and a back adhesive film, the first winding roller 8 is used for winding the back adhesive film 102 in the first material. The printing material with the back adhesive and the back adhesive film is taken as a first material to be wound on the first unreeling roller 1, when the first unreeling roller 1 is unreeled, the rotation torque of the first unreeling roller 1 is driven by the synchronous belt mechanism 11 to drive the first winding roller 8 to rotate in the same direction, and the back adhesive film 102 stripped by the printing material can be wound by the rotation of the first winding roller 8. As the first unreeling roller 1 continuously unreels, the first reeling roller 8 is continuously driven to reel the adhesive film 102, so that the adhesive film 102 is continuously peeled from the printing material. The printing material 103 remaining after the back-adhesive film is peeled off is sequentially transferred through the first roller 201, the

second roller

202a or 202b, and is pressed against the sheet 501 conveyed by the conveying roller 400 by the second roller 202a (embodiment 1) or the third roller 203 (embodiment 2) provided separately.
