Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coil cutting, in particular to a cutting device and a production line. Background Art
[0002] Adhesive tape for tobacco auxiliary materials is suitable for rolling auxiliary materials involved in the cigarette production process, such as kraft paper, coil paper, lining paper, inner card paper, small box transparent paper and strip box transparent paper, etc., which are shipped in round rolls. During use, in order to ensure the continuous operation of the rolling equipment, most rolls are connected with adhesive tape, and then the rolling equipment detection device detects the spliced joints and removes them to avoid stopping the machine to replace auxiliary materials.

The adhesive tape cutting process is generally estimated by the operator visually or by comparing it with the paper roll, and the cutting is generally completed by hand tearing. If the adhesive tape is too long, the excess part will be accidentally stuck to the equipment due to its stickiness, causing the rolling equipment to stop; if the adhesive tape is too short, it may cause the auxiliary material to be bent or the adhesive to be loose and broken, causing the rolling equipment to stop.

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0026] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0027] In the prior art, taking the existing strip box transparent paper roll as an example, when the strip box transparent paper roll in use is about to run out, the operator installs a new strip box transparent paper roll on the spare paper roll rack, and then needs to cut the black adhesive tape to a length of 320 mm, and then attach the adhesive tape to the spare structure with its back facing. The adhesive tape cutting process is generally estimated by the operator visually or by comparing it with the paper roll, and the cutting is generally completed by hand tearing. If the adhesive tape is too long, the excess part will be accidentally stuck to the equipment due to its stickiness, causing the rolling equipment to stop; if the adhesive tape is too short, it may cause the auxiliary material to be bent or the adhesive to be loose and broken, causing the rolling equipment to stop.
[0028] To solve the above problems, this embodiment provides a production line, including a rolling device and a cutting device. Figure 1 The cutting device includes a base 10, a scale 20, a blade 30 and a stopper 40. The scale 20 is connected to the top of the base 10. The adhesive tape of the coiled material can be laid on the surface of the scale 20 and compared with the scale of the scale 20 to obtain an accurate length. The blade 30 is arranged at the starting scale end of the scale 20 for cutting the adhesive tape of the coiled material. The stopper 40 is movably arranged on the scale 20, and the side wall of the stopper 40 can be flush with the scale of the scale 20 to mark the position of the required length of the adhesive tape of the coiled material. The adhesive tape of the coiled material is marked by the stopper 40 and the blade 30 is used to cut the excess adhesive tape to obtain an accurate length of the adhesive tape, improve production quality, avoid shutdown of the rolling equipment, and improve production efficiency.
[0029] Furthermore, the base 10 and the scale 20 are connected by a connecting rod, and the connecting rod is arranged at the central axis of the base 10 and the scale 20 along the extension direction. In this embodiment, the connecting rod is arranged as a long rod extending along the extension direction of the base 10 to fix the base 10 and the scale 20. In other embodiments, a plurality of connecting rods may be provided, and the plurality of connecting rods are arranged at intervals along the extension direction of the base 10.
[0030] Furthermore, the limiter 40 is configured as a limit ring, which is sleeved on the scale 20 and can slide along the scale 20 , and there is a gap between the limit ring and the scale 20 so that the coil adhesive tape can pass through.
[0031] For example, taking the existing transparent paper roll in a box as an example, when the transparent paper roll in use is about to run out, the operator installs a new transparent paper roll in a box on the spare paper roll rack, and then passes the black adhesive tape between the limiting ring and the scale 20. At this time, the side wall of the limiting ring is aligned with 320 mm on the scale 20, and the adhesive tape is pressed down, and the excess part of the adhesive tape will be cut off by the blade 30.
[0032] Specifically, a clearance gap is provided at the position corresponding to the connecting rod of the stopper 40. The connecting rod can be avoided through the gap to avoid affecting the sliding of the stopper 40 on the scale 20.
[0033] Further, the side walls on both sides of the limiting ring are provided with first threaded holes, and the first bolt 41 is threadedly connected with the first threaded hole so that the end face of the first bolt 41 abuts against the side wall of the scale 20, thereby fixing the limiting ring. The position of the limiting ring is fixed by the friction between the end face of the first bolt 41 and the side wall of the scale 20. Specifically, a plurality of first threaded holes are arranged at intervals along the extension direction of the scale 20. In this embodiment, two first threaded holes are arranged on each side of the limiting ring.
[0034] Further, the cutting device further includes a pressing block 50, which can press the non-cutting end of the blade 30 to fix the blade 30. Specifically, the pressing block 50 is set as a concave block, and a second threaded hole 51 is set on the side wall of the concave block. The second bolt is threadedly connected to the second threaded hole 51, so that the end face of the second bolt can abut against the side wall of the scale 20, thereby fixing the pressing block 50. The position of the pressing block 50 is fixed by the friction between the end face of the second bolt and the side wall of the scale 20. In other embodiments, the pressing block 50 and the scale 20 can also be riveted or glued.
[0035] Furthermore, the cutting end of the blade 30 protrudes from the starting scale end of the scale 20 and is tilted downward. The blade 30 is tilted downward to avoid accidental injury to the operator. When cutting the coil, the coil only needs to be pulled downward to make the coil contact with the blade.
[0036] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
