Description

Single-roller switching mechanism for tipping paper laser drilling machine

Technical Field

The utility model relates to a tipping paper laser drilling equipment belongs to the laser beam machining field. The tipping paper laser-beam drilling machine is applied to the tobacco industry. The utility model provides a paper tape single roll switching mechanism for tipping paper laser-beam drilling machine realizes automatic the unqualified part of punching with the paper tape initiating terminal and rejects, switches the qualified paper tape that punches on receiving the paper roll simultaneously.

Background

The tipping paper is special packaging paper for cigarette filter tip. In recent years, tipping paper has been greatly developed and innovated in function and use. With the increasing social health consciousness and national requirements for reducing tar content of cigarette products, punching holes on tipping paper is an effective method for meeting the requirements. Tipping paper laser drilling technology is increasingly applied to cigarette products. The laser drilling of the tipping paper is to use the energy of a focused high-density laser beam to punch a plurality of rows of small holes on the tipping paper, so that air can permeate the tipping paper to dilute harmful substances such as tar, nicotine, CO and the like in smoke, thereby reducing the harm to smokers. With the continuous improvement of China on the tipping paper laser drilling technology, each cigarette is required to meet stable technical indexes, namely, stable hole patterns and density must be drilled on the whole tipping paper length, so that the tipping paper laser drilling machine is required to automatically remove the part with unqualified drilling at the starting end.

The early laser-beam drilling machine adopts a paper tape three-roller switching mechanism to remove the unqualified part punched at the starting end, the mechanism has a complex structure, three sets of rollers are required to move in a matched manner to cut off waste paper in production, and the paper with the structure is cut off in a breaking mode, so that the success rate is only about 80 percent, and the paper is easy to break and cannot be stably produced. Therefore, a novel single-roller switching mechanism is developed and designed and is repeatedly tested. Compared with other similar devices, the mechanism has the following components: 1) the structure is reasonable and simple, the integration level is high, and the assembly and debugging are convenient; 2) the cost is low, the control is convenient, the driving is realized by adopting pneumatic transmission and the guiding is realized by adopting a linear guide rail, so that the high precision is ensured; 3) the reliability is high: because the end paper tape is cut by the cutter, the tension instability caused by breaking the paper tape is avoided, and the success rate is over 95 percent; 4) safe and simple use: an operator only needs to manually wind the paper tape on the switching wheel on the paper collecting roller in a shutdown state, the perforating machine is started, and the whole switching and separating action is automatically completed. The safety of operators is ensured.

SUMMERY OF THE UTILITY MODEL

The mechanism is used in actual production, and the device can accurately and reliably remove unqualified punched parts of the starting end, and simultaneously switch qualified punched paper tapes to meet the functional requirements of equipment on a paper collecting roller. The present invention will be further described below in conjunction with the application of the apparatus to a "tipping paper laser-beam drilling machine".

Drawings

Fig. 1 is the structure diagram of the single-roller switching mechanism of the present invention, which mainly comprises: the paper cutting machine comprises a lifting cylinder 1, an installation base 2, a sliding plate 3, a paper cutting cylinder 4, a cutter 5, an intermediate roller 6, a paper tape 7, an air blowing nozzle 8, a winding shaft 9, a switching wheel 10, a sliding block 11 and a linear guide rail 12.

The whole mechanism is arranged on the installation base 2, so that the mechanism is integrated, and the installation and debugging are convenient. The cutter cylinder 4, the cutter 5, the middle roller 6, the air blowing nozzle 8 and the switching wheel 10 are arranged on the sliding plate 3; the sliding plate 3 is arranged on the sliding block 11 and the linear guide rail 12, so that high movement precision is ensured; the lifting cylinder 1 drives the sliding plate 3 to move up and down along the linear guide rail 12, so that the switching wheel 10 is contacted and separated with the winding shaft 9.

Detailed Description

The single-roller switching mechanism is simple to operate, safe and reliable, and the specific operation process is as follows:

As shown in fig. 1: manually winding the paper tape 7 around a winding shaft 9, an intermediate roller 6 and a switching wheel 10 in sequence in a shutdown state, and then pasting the head of the starting end of the paper tape on the switching wheel 10 through double-sided adhesive tape; starting the lifting cylinder 1 to press down to enable the switching wheel 10 to be contacted with the winding shaft 9; and starting the perforating machine, accelerating rotation of the winding shaft 9, and synchronously rotating the switching wheel 10 to realize winding of the paper tape on the switching wheel 10.

When the linear speed of the paper tape reaches a set value, the paper cutting cylinder 4 drives the cutter 5 to move downwards, the cutter 5 cuts off the paper tape 7, meanwhile, the air blowing nozzle 8 blows air, and a tape head at the inlet side of the cut paper tape is blown into the winding shaft 9; the paper tape is switched to a winding shaft 9 for winding; the lifting cylinder 1 is started to ascend, so that the switching wheel 10 is separated from the winding shaft 9, the switching wheel is slowly stopped, and the whole switching action is finished.
