Abstract

The present invention belongs to the field of tape production technology, especially a degradable tape cutting device and method. In view of the problem of burrs existing in the prior art when sawing and cutting the inner ring sleeve of the tape, the following scheme is proposed, including a mounting seat, an intermittent propulsion mechanism and a gate cutting mechanism: the mounting seat includes a main table, a side table slidably connected to the side of the main table, and a rear fixed seat slidably connected to the rear side of the main table. The main table is an overall 1 / 4 circular structure, and a large circular hole is opened at the center of the main table. A vertical shaft tube is rotatably connected in the large circular hole, and a rotating support is fixed to the top of the shaft tube. The present invention can not only avoid burrs on the end face during sawing, but also because the raw material sleeve always has a sleeve rod matched with the inner diameter inside the incision to play the role of expansion support, thereby effectively preventing the incision from collapsing or being crushed, thereby improving the quality and neatness of the product incision.

Description

Technical Field

[0001] The present invention relates to the technical field of adhesive tape production, and in particular to a degradable adhesive tape cutting device and method. Background Art

[0002] Tape cutters are often used to cut tapes. This type of cutter can be used to cut long cylindrical tape sleeves into ring-shaped tape inner rings, which are used to wrap tape. Since the thickness of the tape raw material sleeve is relatively thin, it is easy to crush the sleeve due to poor control of the force when using general guillotine cutting, thus affecting the subsequent winding operation.

[0003] After searching, it is found that the cutting method in the prior art mostly adopts sawing, which is widely used because it has the advantage of preventing the pressure caused by the gate knife from crushing the tape raw material sleeve. However, no matter how dense the teeth are, there will be a defect in sawing, that is, the incision is uneven and it is easy to fuzz at the incision. If cooling measures are not taken in time, it may even cause burning of the burrs, affecting the overall aesthetics in the later stage. Therefore, we propose a new cutting method to avoid the occurrence of this phenomenon. Summary of the invention

[0015] A method for cutting a degradable tape in an annular shape, comprising the following steps:

[0016] S1: Before loading, make sure that all electrical appliances are powered off; first select the appropriate sleeve rod length according to the length of the raw material sleeve, then simultaneously pull the side platform 1 and the rear fixed seat to the same distance according to the length of the sleeve rod, and fix them, then control all the propulsion racks to return to the initial position, that is, the tail end is close to the magnet and is attracted by the magnet;

[0017] S2: Then put the raw material sleeve on the sleeve rod at the front, then screw the plug on, and move the sleeve rod with the raw material sleeve so that its bottom breaks through the positioning of the positioning rod until it rotates to the next positioning. At this time, the sleeve rod with the raw material sleeve crosses the guide cover and rests in the middle of the thin waist roller;

[0018] At this time, the main motor in the gate cutting mechanism and the electric control positioning pin and the reduction motor in the intermittent propulsion mechanism are started simultaneously. At this time, the extension rod of the electric control positioning pin is extended, and the conveyor belt is tightened while the rubber pressure wheel is tightly pressed against the circumferential outer wall of the receiving wheel. At this time, the intermittent propulsion of the propulsion rack and the raw material sleeve can be realized under the drive of the reduction motor;

[0019] S3: At the same time, the gate cutting method in which the gate cutter in the gate cutting mechanism moves down quickly and up slowly can greatly reduce the burrs at the incision and prevent the raw material sleeve from being damaged during withdrawal; the triangular holder can keep the incision more neat and prevent curling.

[0020] The beneficial effects of the present invention are:

[0021] 1. By setting a cutting method that is sleeved on a sleeve rod and can be pushed forward piece by piece as the intermittent pushing mechanism runs, not only can the burrs on the end face during sawing be avoided, but also because the raw material sleeve always has a sleeve rod matched with the inner diameter inside the incision to play the role of expansion and support, it can effectively prevent the incision from collapsing or being crushed, thereby improving the quality and neatness of the product incision.

[0022] 2. By setting the positioning rod and the corresponding V-shaped notch, when loading, when the sleeve rod with the raw material sleeve is running towards the gate-cutting mechanism, the tip is disengaged from the V-shaped notch and can be rotated at will. When the end of the sleeve rod is rotated to the gate-cutting position, one of the V-shaped notches is engaged with the tip of the end of the positioning rod, thereby achieving positioning. At the same time, gate-cutting and loading can be carried out.

[0023] 3. By setting a sleeve rod with a ball and a plug, not only can the feeding become smoother, but also, with the setting of the plug, when the plug rotates to the gate cutting position together with the sleeve rod and the raw material sleeve, the gap distance between the outer wall of the plug and the cutting position of the raw material sleeve is reduced, thereby preventing the cutting position from being crushed and preventing the raw material sleeve from being thrown out during the rotation.

[0024] 4. Through the set electric control positioning pin and concentric wheel, when the rotating support platform rotates to the gate cutting position with the sleeve rod and the raw material sleeve, the half gear 2 at the tail end of the sleeve rod and the receiving wheel rotate to the advancing position. At this time, the extension rod of the electric control positioning pin is extended to tighten the conveyor belt and press the rubber pressure wheel tightly against the circumferential outer wall of the receiving wheel. At this time, the intermittent advancement of the advancing rack and the raw material sleeve can be realized under the drive of the reduction motor. BRIEF DESCRIPTION OF THE DRAWINGS
