Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

A label cutting unit on a labeling machine comprises a support frame 1, a rotary roller 2 and a cutting knife roller 3 which are rotationally connected to the support frame 1, a knife rest 4 arranged on the cutting knife roller 3, a blade 5 fixedly connected to the knife rest 4 and an elastic steel sheet 6, wherein one side of the elastic steel sheet 6 is fixed on the cutting knife roller 3, the knife rest 4 is detachably fixed on the other side of the elastic steel sheet 6, the knife rest 4 and the cutting knife roller 3 are not in contact with each other to form a gap 7, an arc-shaped pillow plate 8 is fixedly connected to the rotary roller 2, and the rotary roller 2 can drive the cutting knife roller 3 to synchronously rotate and enable the blade 5 to be pressed on the outer surface of the pillow plate 8.

When a continuous label passes through the rotating roller 2 and the cutting knife roller 3, the label is clamped on the pillow plate 8, when the pillow plate 8 and the blade 5 are butted with each other along with the rotation of the rotating roller 2 and the cutting knife roller 3, the blade 5 can cut the label, in addition, because the knife rest 4 is connected to the cutting knife roller 3 by the elastic steel sheet 6, and the gap 7 is arranged between the knife rest 4 and the cutting knife roller 3, when the blade 5 is butted on the pillow plate 8, the blade 5 can be pressed and moved backwards relatively to form a buffer for the blade 5, and simultaneously, the better cutting of the label can be facilitated, and then the elastic steel sheet 6 can drive the knife rest 4 to move to enable the blade 5 to move back to the initial position.

Two machining planes 13 are formed by cutting in the axial direction of the cutoff roller 3, and the two plane edge cuts are perpendicular to each other, wherein one side of the elastic steel piece 6 is fixed to one of the machining planes 13, the tool rest 4 is provided to the other machining plane 13, and the tool rest 4 is not in contact with this machining plane 13. This facilitates the stable attachment of the blade holder 4 and the cutter roller 3 to the cutter roller 3, making the cutting of the label by the blade 5 more stable.

Referring to fig. 3, a plurality of fixing screws 9 are respectively disposed on two sides of the elastic steel sheet 6, wherein the fixing screw 9 on one side of the elastic steel sheet 6 penetrates through the elastic steel sheet 6 and is screwed into the cutting knife roll 3, and the fixing screw 9 on the other side of the elastic steel sheet 6 penetrates through the elastic steel sheet 6 and is screwed into the knife rest 4, so as to stably fix the knife rest 4 and the elastic steel sheet 6 to the cutting knife roll 3, and facilitate the detachment thereof when the cutting knife roll 3 needs to be repaired or replaced.

Wherein the diameter ratio of the rotating roller 2 and the cutting knife roller 3 is N: 1(N is an integer greater than or equal to 1), N pillow plates 8 are arranged on the rotating roller 2, and N pillow plates 8 are circumferentially and uniformly distributed on the rotating roller 2, for example, when the diameter ratio of the rotating roller 2 to the cutting knife roller 3 is 2: 1, two pillow plates 8 are arranged on the rotating roller 2, the two pillow plates 8 are uniformly distributed on the circumference of the rotating roller 2, and one pillow plate 8 is butted with the blade 5, so that after the blade 5 rotates for one circle, the rotating roller 2 just rotates for half a circle, and the blade 5 is butted with the other pillow plate 8; when the diameter ratio of the rotating roller 2 to the cutting knife roller 3 is 1: 1, namely the diameter of the rotary roller 2 is the same as that of the cutting knife roller 3, only one pillow plate 8 is arranged on the rotary roller 2, after the blade 5 is abutted with the pillow plate 8, when the cutting knife roller 3 rotates for one circle, the rotary roller 2 just rotates for one circle to make the blade 5 abutted with the pillow plate 8 again, so as to cut off the label arranged on the rotary roller 2. When the diameter ratio of the rotating roller 2 to the cutting knife roller 3 is 1: 1, rotating roll 2 and cutting off knife roll 3's diameter is the same promptly, can also set up two pillow boards 8 on rotating roll 2, can set up two blades 5 on cutting off knife roll 3, and when cutting off knife roll 3 and rotate the round, rotating roll 2 just also rotates the round and makes two blades 5 and two pillow boards 8 dock mutually to will set up the label on rotating roll 2 and cut off twice.

As shown in fig. 2, the upper end of the roll shaft of the rotating roll 2 penetrates the upper end of the supporting frame 1 and is fixed with a main gear 10, the roll shaft of the cutting knife roll 3 penetrates the upper end of the supporting frame 1 and is fixed with a pinion 11, the main gear 10 and the pinion 11 are meshed and connected with each other, and the transmission ratio of the main gear 10 and the pinion 11 is the same as the diameter ratio of the rotating roll 2 and the cutting knife roll 3, so that when the roll shaft of the rotating roll 2 is driven to rotate by a motor, the pinion 11 can be driven to operate to rotate the cutting knife roll 3, and the roll shafts of the rotating roll 2 and the cutting knife roll 3 are not required to be respectively provided with motors to drive the rotating roll 2 and the cutting knife roll 3 to operate.

The above-mentioned main gear 10 is connected to the roll shaft of the rotary roll 2 by means of the expansion coupling sleeve 12, and the pinion 11 is fixedly connected to the roll shaft of the cutting knife roll 3, or the main gear 10 is fixedly connected to the roll shaft of the rotary roll 2, and the pinion 11 is connected to the roll shaft of the cutting knife roll 3 by means of the expansion coupling sleeve, because the cutting unit is used, it is necessary to make the blade 5 abut against the pillow plate 8, and to make the main gear 10 mesh with the pinion 11, the relative position of the main gear 10 and the rotary roll 2 or the pinion 11 and the cutting knife roll 3 is conveniently adjusted by means of the expansion coupling sleeve 12.

Still rotate on support frame 1 and be connected with and draw mark roller 14 and rubber compression roller 15, draw mark roller 14 and rubber compression roller 15 and be in one side of rotatory roller 2, and draw mark roller 14 and the mutual laminating of rubber compression roller 15's surface, when making the label move on rotatory roller 2, can make the label pass through between drawing mark roller 14 and the rubber compression roller 15 earlier to make the label level and smooth stable removal to carry out the cutting-off processing on rotatory roller 2.

The utility model is characterized in that the elastic steel sheet 6 is arranged on the cutting knife roller 3, and the knife rest 4 is fixed on the elastic steel sheet 6, at the same time, a gap 7 is arranged between the cutter frame 4 and the cutting knife roller 3, when the label is moved between the rotating roller 2 and the cutting knife roller 3, when the blade 5 and the pillow plate 8 on the rotating roller 2 are butted with each other, the label can be pressed to be cut open, and when the blade 5 and the pillow plate 8 are butted, due to the arrangement of the elastic steel sheet 6 and the gap 7, the blade 5 can play a certain buffer role during cutting, and simultaneously, the blade 5 can be more tightly pressed on the pillow plate 8 to cut the label, in addition, by using the arrangement of the main gear 10 and the pinion 11, the synchronous operation of the rotating roller 2 and the cutting knife roller 3 can be controlled by using only one motor control system, so that certain resources are saved, and the cutting unit is more concise and convenient to operate.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
