Description

A slitting and rewinding machine

technical field

The utility model relates to the field of packaging machinery and equipment, in particular to a slitting and rewinding machine.

Background technique

The slitting and rewinding machine is the main equipment for the production of cash register paper. It is a machine that cuts and arranges the base paper with a large diameter and a large diameter, and then rewinds it into a finished paper roll that is uniform and suitable inside and outside. The main task is to remove the raw paper. Cut the entire base paper into several widths that meet the user's specifications, and control the roll diameter of the finished paper roll to meet the factory specifications. The traditional slitting and rewinding machine is to install the upper cutter head on a fixed knife holder, the upper knife is installed on the upper cutter head, the upper knife rests on the cutting edge of the lower knife, and the lower knife drives the upper knife to rotate and cut the material. Since the sum of the width of the knife rest and the upper knife disc is much greater than 15mm, it is impossible to complete the slitting and rewinding of the paper roll with a width of 15mm.

Utility model content

The technical problem to be solved by the utility model is to provide a slitting and rewinding machine with high processing precision and a minimum slitting and rewinding width of 15mm.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A slitting and rewinding machine, comprising a slitting and rewinding machine body, the slitting and rewinding machine body including an upper cutter shaft, a lower cutter shaft, an upper cutter disc, an upper knife and a lower knife, and the upper cutter disc is arranged on On the upper cutter shaft, several upper cutter heads are arranged on the upper cutter shaft, and an upper knife is fixedly installed on each of the upper cutter heads, and the lower cutter is arranged on the lower cutter shaft, and on the lower cutter shaft There are several lower knives, the number of the upper cutter head is the same as that of the lower knives, the upper cutter shaft can rotate, and can move slightly in the axial direction, and the right end of the upper cutter shaft is provided with a screw fine-tuning mechanism.

As a further improvement of the utility model:

Further, a support bearing is provided at the left end of the upper cutter shaft.

Further, the supporting bearing is set as a single row needle bearing.

Further, the thickness of the upper cutterhead is set to 15mm.

Further, the thickness of the lower knife is set to 15mm.

Compared with the prior art, the beneficial effect of the utility model is: since the upper cutter head is arranged on the upper cutter shaft, and the lower cutter is arranged on the lower cutter shaft, the upper cutter shaft can rotate, and can be The axial direction carries out slight movement, and the right end of the upper cutter shaft is provided with a screw fine-tuning mechanism, the thickness of the upper cutter head is set to 15mm, and the thickness of the lower cutter is set to 15mm, so that the slitting and rewinding of the utility model With high precision, the width of slitting and rewinding is narrower, and it can be slitting and rewinding into paper rolls with a width of 15mm.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

As shown in Figure 1, a kind of slitter rewinder, comprises slitter rewinder body 100, and described slitter rewinder body 100 comprises upper cutter shaft 4, lower cutter shaft 2, upper cutter head 5, upper cutter 7 and the lower cutter 3, the upper cutter 7 discs are arranged on the upper cutter shaft 4, and the upper cutter shaft 4 is provided with several upper cutter heads 5, and each upper cutter head 5 is fixedly equipped with an upper cutter 7. The lower knife 3 is set on the lower knife shaft 2, and the lower knife shaft 2 is provided with several lower knives 3. The number of the upper knife disc 5 is the same as that of the lower knife 3. The upper knife shaft 4 It can rotate and move slightly in the axial direction. The right end of the upper cutter shaft 4 is provided with a screw fine-adjustment mechanism 6 .

The left end of the upper cutter shaft 4 is provided with a support bearing 1 . The support bearing 1 is set as a single row needle roller bearing. The thickness of the upper cutterhead 5 is set to 15mm. The thickness of the lower knife 3 is set to 15mm.

Principle of the utility model: the utility model is provided with several upper cutter heads 5 on the upper cutter shaft 4, each upper cutter head 5 is fixedly equipped with an upper knife 7, and the lower cutter shaft 2 is provided with several lower knives 3, so The number of the upper cutter heads 5 is the same as the number of the lower cutters 3, and each of the upper cutter heads 5 has a thickness of 15mm, all of which are set on an upper cutter shaft 4 that can rotate and move in a small amount in the axial direction. Lower cutter 3 also makes 15mm and is sleeved on the lower cutter shaft 2. The support bearing 1 of the upper cutter shaft 4 is a single-row needle roller bearing. The inner and outer rings of the support bearing 1 can move relative to the axial direction. One end of the upper cutter shaft 4 is equipped with a screw fine-tuning mechanism 6, and adjusting the screw fine-tuning mechanism 6 makes the upper cutter shaft 4 The axial movement drives the upper knife 7 and the lower knife 3 on the upper cutter head 5 to be close to and separate from each other. In the utility model, since the upper cutter head is arranged on the upper cutter shaft, and the lower cutter is arranged on the lower cutter shaft, the upper cutter shaft can rotate and can move in a small amount in the axial direction. The upper cutter shaft The right end is provided with screw fine-tuning mechanism, and the thickness of described upper cutterhead is set as 15mm, and the thickness of described lower knife is set as 15mm, makes the precision of slitting and rewinding of the present utility model high, and the width of slitting and rewinding is narrower, It can be cut and rewound into rolls with a width of 15mm.

The utility model is not limited to the above-mentioned specific implementation manners. For those of ordinary skill in the art, starting from the above-mentioned concept without creative work, various transformations made all fall within the protection scope of the utility model.
