Description
Technical Field
The invention belongs to the technical field of non-woven machinery, and particularly relates to a cloth cutting device of a non-woven fabric winding machine.
Background
The non-woven fabric winding machine is an indispensable machine in a complete set of non-woven product production line, and particularly, the winding machine winds the non-woven fabric which is needled by a needle machine in the previous process, the non-woven fabric is cut off by a fabric cutting device after the diameter of a fabric roll meets the required requirement, then a fabric roller is started to wind, and the process is circulated. The general structure and the specific operating principle of the nonwoven fabric winder can be further understood by reading the patent documents such as CN201545539U (a nonwoven fabric winder), CN211225653U (a nonwoven fabric winder), CN209038665U (a nonwoven fabric winder) and CN213084867U (a nonwoven fabric winder).
In order to embody the overall effect of the structure, the fabric cutting device is usually matched with the non-woven fabric winding machine, fig. 4 shows the fabric cutting device of the non-woven fabric winding machine common in the prior art, and the working process is as follows: when the diameter of the cloth roll 10 reaches the required degree of the process (that is, when the cloth roll reaches the full roll), the cylinder 20 works to drive the cylinder column 201 to drive the swing arm 30, the motor frame 40 and the motor 401 move downwards, and when the belt drives the motor 401 to move rapidly, the motor 401 drives the disc slice 4011 (also called as a cutter head) fixed on the motor shaft to move at a high speed, so that the non-woven fabric passing through the cloth supporting mechanism 1 is cut off, that is, the non-woven fabric positioned below the disc blade 4011 is cut off. This cloth cutting device is substantially similar to the cloth cutting device provided on the spreader of a garment machine (also called "spreading machine"), for which the "full-automatic cutting mechanism of the spreader" recommended by CN201416113Y and the "corresponding cutting device of the spreader" provided by CN209957085U can also be used.
Although the above-mentioned cutting device of the nonwoven fabric winding machine shown in fig. 4 can satisfy the requirement of cutting the nonwoven fabric, there are the following technical problems: the non-woven fabric is cut by the disc blade in the process of winding the fabric roll, namely the non-woven fabric is cut by the disc blade in the process of leading out, and the higher the speed of the needle loom is, the faster the speed of winding the fabric roll is correspondingly, and the higher the speed of leading out the non-woven fabric is, so the cut of the non-woven fabric cut by the disc blade is always inclined from one side of the non-woven fabric to the other side, namely the cut is a bevel cut, and the non-woven fabric at the bevel cut part needs to be removed when used by downstream manufacturers, thereby causing waste. On the other hand, for the nonwoven products with severe quality requirements, the bevel is not usually allowed when the cloth head and the cloth tail are cut. The reason why the cloth incision is not inclined in the aforementioned cloth spreading machine is that the cloth is pressed, i.e., temporarily cut in a stationary state, and thus the cloth cutting device on the cloth spreading machine is not suitable for cutting the nonwoven fabric in a moving state. Of course, if the movement of the nonwoven fabric is temporarily stopped during the time period of cutting by the disc blade, on the one hand, the nonwoven fabric is difficult or even impossible to cut because the nonwoven fabric stops moving and loses its tensioning effect (i.e., is in a loose state), and on the other hand, it is objectively impossible to temporarily stop the previous needle loom for cutting at the time of full lap. Since there is no teaching disclosed in the patent and non-patent documents disclosed so far as it is helpful to use to remedy the above-mentioned technical problems, the applicant has made a useful search to develop the technical solutions to be described below.

In this state, specifically, the pair of swing arms 4 drive the cloth supporting mechanism 1 and the nonwoven fabric cutting mechanism 3 to be in a state of retreating from cutting the nonwoven fabric 9 by the action of the chain on the swing arm drive wheel 5 by the swing arm actuator wheel drive device. When the diameter of the roll 10 has reached the level required by the process (usually by a meter or similar metering device not shown in the figures and feeding back a signal to the electrical controller), the latter issues a command to cut the non-woven fabric 9.
Referring to fig. 3 in conjunction with fig. 1 and 2, when the non-woven fabric 9 is to be cut off by changing the roll, under the command of the electrical controller, the swing arm actuating wheel driving device operates (rotates) the swing arm actuating wheel 5 in the reverse direction to displace the front ends of the pair of swing arms 4 upward, i.e. clockwise, relative to the state of fig. 2, and at the same time, drives the cloth supporting mechanism 1 and the non-woven fabric cutting mechanism 3 into a fabric cutting operation state, in which the tensioning shaft 33 is in a tensioned state with respect to the non-woven fabric 9 due to the operation of the pair of pivot arm driving cylinders 38, and in a fabric supporting state of the cloth supporting mechanism 1, the non-woven fabric cutting knife 35 is in a good contact state with the passing non-woven fabric 9, in which the non-woven fabric passing through the non-woven fabric cutting knife serrated edge 351 is cut off, that is, the nonwoven fabric passing there is instantaneously cut by the nonwoven fabric cutting blade serrated edge 351, and after the top of the nonwoven fabric 9 is cut, the swing arm actuator 5 is rotated in the reverse direction, and the pair of swing arms 4, the cloth supporting mechanism 1, and the nonwoven fabric cutting mechanism 3 of the present invention return to the state shown in fig. 2. And the head of the cut non-woven fabric 9 falls onto the standby cloth roller 7b, and in the same way (principle) as the above, the non-woven fabric 9 is wound under the rotation of the standby cloth roller 36 driven by the corresponding cloth guide roller shaft head pivot driving device, and in the winding process, along with the gradual increase of the diameter of the cloth roll 10 on the standby cloth roller 7b, the cloth roll 10 gradually moves to the left under the moving action of the second sliding blocks 611 corresponding to the front and the back of another pair and respectively slidably arranged on the other pair of guide rails 61. In the above process, the former cloth roller 7a is unwound by the on-line operator, and since the unwinding method belongs to the prior art, for example, but not limited to, CN108639810A (a cloth winding machine facilitating the roll replacement), the applicant does not give any further details, and the former cloth roller 7a after unwinding the cloth roll 10 is changed to the spare cloth roller 7b to be in the position shown in fig. 2, while the spare cloth roller 7b in the process of winding substantially plays the role of the cloth roller 7 a.
In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
