The nonwoven fabric unwinding device 1 according to the present application is described below with reference to fig. 1 and 2.
The nonwoven fabric unwinding device 1 according to the present application includes an unwinding roller 111, a driving motor 11, a guide frame 12, a fabric guide roller, a tension roller, and a sensor.
Wherein, the driving motor 11 is connected with the unwinding roller 111 to drive the unwinding roller 111 to rotate. The nonwoven fabric roll is disposed on the unwinding roller 111 to be unwound as the unwinding roller 111 rotates. The cloth guide roller is mounted on the guide frame 12. The tensioning roller is used for tensioning non-woven fabrics 21, the tensioning roller is installed on the guide frame 12 and is movable along the vertical direction of the guide frame 12 below the cloth guide roller, and the sensor is used for detecting the tensioning roller.
The nonwoven fabric 21 is generally processed by unwinding the nonwoven fabric roll 2, and in this application, the nonwoven fabric roll 2 is set on an unwinding roller 111, and the driving motor 11 drives the nonwoven fabric roll 2 to rotate by driving the unwinding roller 111 to rotate, so that the nonwoven fabric roll 2 is unwound. During the continuous unwinding process, the diameter of the nonwoven fabric roll 2 is continuously reduced, and the length of the nonwoven fabric 21 discharged by one rotation is also reduced, for example, when the diameter of the nonwoven fabric roll 2 is 1 meter, the driving motor 11 drives the unwinding roller 111 to rotate one rotation to discharge the nonwoven fabric 21 about 3 meters long. When the diameter of the nonwoven fabric roll 2 is 0.2 m, the driving motor 11 drives the unwinding roller 111 to rotate one turn to release only about 0.6 m of the nonwoven fabric 21, which is a big difference.
Among the correlation technique, the unwinding speed of non-woven fabrics can't be discerned to non-woven fabrics unwinding device, more can't be at the in-process tensioning non-woven fabrics all the time of unreeling, consequently can not adapt to the production of spring in bags, breaks down easily.
According to the non-woven fabric unreeling device 1, the unreeling roller 111 is connected with the driving motor 11, the non-woven fabric reel 2 is arranged on the unreeling roller 111, the driving motor 11 provides power for unreeling the non-woven fabric reel 2, and the rotating speed of the driving motor 11 can be adjusted adaptively according to the unreeling condition of the non-woven fabric reel 2.
Specifically, the nonwoven fabric 21 unwound by the unwinding roller 111 passes through the guide frame 12, and the guide frame 12 is provided with a fabric guide roller. Wherein the fabric guide roller can be a plurality of, and under the condition that the fabric guide roller is two, non-woven fabrics 21 is walked around the fabric guide roller from the upside earlier and is extended to the downside, and upwards extends after the tensioning roller is walked around from the downside again, walks around another fabric guide roller from the upside again, and the fabric guide roller can make non-woven fabrics 21 keep leveling in transmission process.
The tensioning roller is arranged at the lower side between the two cloth guide rollers to be suitable for tensioning the non-woven fabric 21, so that the non-woven fabric 21 is kept in a tensioned state in the vertical direction in the guide frame 12, and the tension of the non-woven fabric 21 in the transmission process is sufficient, wherein the cloth guide rollers can utilize the gravity of the cloth guide rollers to improve the tension of the non-woven fabric 21, and can also be connected with other power devices to enable the cloth guide rollers to tension the non-woven fabric 21.
According to the nonwoven fabric unwinding device 1 of the present application, the tension roller may be vertically movable on the guide frame 12. In the process of gradually unwinding the non-woven fabric unwinding device 1, the unwinding speed of the non-woven fabric 21 is gradually reduced, and the speed of the material end of the downstream non-woven fabric 21 is always kept consistent, so that the supply of the non-woven fabric 21 is insufficient, and the tension of the non-woven fabric 21 is increased. The tension of the nonwoven fabric 21 is increased, and the tension roller tends to move upward on the guide frame 12. The sensor can detect the removal of tensioning roller, detects the removal back of tensioning roller at the sensor, and non-woven fabrics unreeling device 1 can adjust driving motor 11's rotational speed according to the position that detects the tensioning roller to guarantee non-woven fabrics unreeling device 1's the speed of unreeling, improve non-woven fabrics unreeling device 1's reliability. Of course, the sensor can also detect the rotating speed of the tensioning roller, the rotating speed of the tensioning roller is used for judging whether the unwinding speed of the non-woven fabric unwinding device 1 meets the requirement of a downstream end, and the sensor adjusts the unwinding speed of the non-woven fabric unwinding device 1 through the state of the tensioning roller.
Wherein the tensioning roller is vertically movable on the guide frame 12. The guide frame 12 is generally disposed on the ground, and the vertical direction of the guide frame 12 may be a direction vertical to the ground, and the tension roller moves in an up-down direction vertical to the ground. Of course, the vertical direction of the guiding frame 12 may also be a certain angle with the direction perpendicular to the ground, the angle between the vertical direction and the direction perpendicular to the ground is related to the arrangement condition of the tensioning roller, and the angle between the vertical direction and the direction perpendicular to the ground is generally within 30 degrees, but there is an exception, and the angle between the vertical direction and the direction perpendicular to the ground is determined according to the arrangement between the tensioning roller and the cloth guiding roller.
The nonwoven fabric unwinding device 1 according to the present application is provided with an unwinding roller 111 adapted to drive the nonwoven fabric roll 2 for unwinding, and a drive motor 11 for driving the unwinding roller 111. The non-woven fabrics 21 after unreeling passes through the leading truck 12, is provided with the fabric guide roll that leads non-woven fabrics 21 and carries out the tensioning roller that tightens non-woven fabrics 21 on the leading truck 12, and the tensioning roller can remove in the vertical of leading truck 12 to be suitable for carrying out the tensioning with non-woven fabrics 21 and guarantee that the transmission of non-woven fabrics 21 keeps stable. The non-woven fabric unreeling device 1 is further provided with a sensor, the sensor is used for detecting the tensioning roller, for example, the sensor can detect the position, the rotating speed and the like of the tensioning roller so as to judge whether the unreeling speed of the non-woven fabric 21 meets the supply requirement of the downstream. The non-woven fabric unreeling device 1 can adjust the driving motor 11 according to information detected by the sensor, and unreeling stability and reliability of the non-woven fabric unreeling device 1 are guaranteed.
According to an embodiment of the present application, the driving motor 11 controls the unwinding speed of the unwinding roller 111 according to the position of the tension roller detected by the sensor.
Specifically, during the unwinding process of the nonwoven fabric unwinding device 1, the diameter of the nonwoven fabric roll 2 is continuously reduced, while the rotation speed of the driving motor 11 and the rotation speed of the unwinding roller 111 are kept unchanged, so that the unwinding speed of the nonwoven fabric 21 is reduced. The required amount of the downstream end of the nonwoven fabric unwinding device 1 is always the same, so that the tension on the nonwoven fabric 21 is increased, the position of the fabric guide roller on the guide frame 12 cannot be changed, and the tension on the nonwoven fabric 21 is increased to cause the tension roller to move upward. After the tensioning roller moves a certain distance, the sensor detects the tensioning roller, the non-woven fabric unwinding device 1 adjusts the rotating speed of the driving motor 11, the unwinding speed of the non-woven fabric 21 is increased, and the speed of unwinding can meet the speed of the downstream end for the non-woven fabric 21.
When the unwinding speed of the non-woven fabric unwinding device 1 is too high, the tension on the non-woven fabric 21 is reduced, and the tension roller moves downwards. After the sensor detects the tensioning roller, non-woven fabrics unwinding device 1 adjusts driving motor 11's rotational speed, reduces non-woven fabrics 21's unwinding speed, makes the speed of unreeling satisfy the demand speed of low reaches end to non-woven fabrics 21 basically, prevents that non-woven fabrics 21 from gluing to link accumulational phenomenon and taking place.
According to an embodiment of the present application, the sensor is provided on the guide frame 12, wherein the sensor may be a plurality of sensors, and the plurality of sensors may be provided at intervals along the movement track of the tension roller, and the tension roller is detected by the sensor at the corresponding position, so as to determine whether the tension force on the nonwoven fabric 21 is appropriate or not according to the position of the tension roller in the vertical direction.
According to an embodiment of the present application, the sensor includes a first sensor 151 for detecting that the tension roller moves upward to the upper limit position, the first sensor 151 may be disposed at the upper end of the guide frame 12 and located at an upper side of all other sensors, and when the tension roller moves upward to the upper limit position, the driving motor 11 stops driving the unwinding roller 111 to unwind.
The reason for the upward movement of the tension roller to the upper limit position may be caused by two cases.
The first cause of the tension roller moving to the upper limit position is: the unwinding speed of the non-woven fabric unwinding device 1 is too slow, so that the requirement of the downstream end of the non-woven fabric unwinding device 1 cannot be met, the tension on the non-woven fabric 21 is increased, and the tensioning roller moves upwards. Although the sensor detects the upward movement of the tension roller, the tension on the nonwoven fabric 21 cannot be rapidly changed by adjusting the speed of the driving motor 11, that is, the adjustment of the tension on the nonwoven fabric 21 has a certain delay after the speed of the driving motor 11 is changed, and the tension of the nonwoven fabric 21 is too high, so that the upward movement speed of the tension roller is fast, and the tension roller rapidly moves to the position of the first sensor 151. At this moment, the tension on the non-woven fabric 21 cannot be effectively adjusted only by increasing the rotating speed of the driving motor 11, the non-woven fabric unwinding device 1 needs to be rearranged after being stopped, the non-woven fabric 21 is prevented from being damaged by continuous work of the non-woven fabric unwinding device 1, the non-woven fabric unwinding device 1 is also prevented from being damaged, the non-woven fabric unwinding device 1 has a protection mechanism, and the reliability of the non-woven fabric unwinding device 1 is improved.
The second cause of the tension roller moving to the upper limit position is: the non-woven fabric 21 is bonded together, so that the non-woven fabric 21 cannot be continuously unreeled, and the tension of the non-woven fabric 21 is rapidly increased due to the fact that the non-woven fabric 21 cannot be continuously unreeled, so that the tension roller rapidly moves upwards, and the first sensor 151 is triggered. The non-woven fabrics 21 bonds the back together, needs the workman to arrange in order the non-woven fabrics 21 again, prevents that non-woven fabrics unwinding device 1's continuation work from causing the damage to non-woven fabrics 21, also avoids non-woven fabrics unwinding device 1's damage, makes non-woven fabrics unwinding device 1 have the safeguard mechanism, improves non-woven fabrics unwinding device 1's reliability.
According to an embodiment of the present application, the sensor further includes a second sensor 152 for detecting that the tension roller moves downward to a lower limit position, the second sensor 152 is vertically below the first sensor 151, and the driving motor 11 stops driving the unwinding roller 111 to unwind when the tension roller moves downward to the lower limit position.
The reason when the tensioning roller is moved down to the lower extreme position can be caused by two situations.
The first cause of the tension roller moving to the lower extreme position is: the roll 2 of nonwoven fabric has been unwound, the tension on the nonwoven 21 has disappeared and the tensioning roller falls to the lower vertical limit due to its own weight. The second sensor 152 can now detect the position of the tensioning roller and stop the nonwoven unwinding device 1 for the purpose of rearranging the nonwoven roll 2.
The second cause of the tension roller moving to the lower limit position is: the nonwoven fabric 21 is cut off, and the nonwoven fabric 21 connected to the downstream end continues to move after the cut off, and the nonwoven fabric 21 at the upstream end cannot enter the guide frame 12, so that the tension on the nonwoven fabric 21 is lost, and the tension roller falls to the lower limit position in the vertical direction due to its own weight. The second sensor 152 can now detect the position of the tensioning roller and stop the nonwoven unwinding device 1 to rearrange the nonwoven 21.
According to an embodiment of the present application, the sensor further comprises a third sensor 153, the third sensor 153 being located vertically between the first sensor 151 and the second sensor 152. When the tension roller is detected by the third sensor 153 in the upward movement process, the driving motor 11 increases the unwinding speed of the unwinding roller 111, and when the unwinding speed of the nonwoven fabric unwinding device 1 meets the required speed of the downstream end, the tension on the nonwoven fabric 21 makes the tension roller located between the third sensor 153 and the second sensor 152. After the unwinding speed of the non-woven fabric unwinding device 1 is reduced, the tension on the non-woven fabric 21 is gradually increased, the tensioning roller moves upwards until the non-woven fabric unwinding device 1 moves to the position of the third sensor 153, and the unwinding speed is increased by the non-woven fabric unwinding device 1 so that the unwinding speed of the non-woven fabric unwinding device 1 can meet the requirement speed of a downstream end.
In an embodiment of the present application, the sensor further includes a fourth sensor 154, the fourth sensor 154 is vertically located between the third sensor 153 and the second sensor 152, and when the tension roller is detected by the fourth sensor 154 during the downward movement process, the driving motor 11 reduces the unwinding speed of the unwinding roller 111 to the normal unwinding speed.
After the unwinding speed of the non-woven fabric unwinding device 1 is increased, the unwinding speed of the non-woven fabric 21 may be slightly higher than the required speed of the non-woven fabric 21 at the downstream end. At this moment, the tension of the non-woven fabric 21 is reduced, the tension roller vertically moves downwards to the position of the fourth sensor 154, the unwinding speed of the non-woven fabric unwinding device 1 is reduced to the normal unwinding speed by adjusting the rotating speed of the driving motor 11 so as to enable the unwinding speed of the unwinding roller 111, the unwinding speed of the non-woven fabric unwinding device 1 is guaranteed to be no longer greater than the required speed of the downstream end, and the tension of the non-woven fabric 21 in the non-woven fabric unwinding device 1 is guaranteed to be kept within a stable range.
By providing the first sensor 151 and the second sensor 152, the tension of the nonwoven fabric 21 in the nonwoven fabric unwinding device 1 is always maintained within a stable range. When the tension on the nonwoven fabric 21 exceeds or falls below a certain threshold value, the nonwoven fabric unwinding device 1 is stopped to protect the nonwoven fabric unwinding device 1. Meanwhile, by the third sensor 153 and the fourth sensor 154, the unwinding speed of the non-woven fabric unwinding device 1 can be dynamically adjusted, so that the unwinding stability of the non-woven fabric unwinding device 1 is improved, and the failure rate of the non-woven fabric unwinding device 1 is reduced.
According to an embodiment of the present application, the distance between the fourth sensor 154 and the third sensor 153 is smaller than the distance between the fourth sensor 154 and the second sensor 152, and the applicant finds that the unwinding speed of the nonwoven fabric unwinding device 1 can be better adjusted by setting the distance between the fourth sensor 154 and the third sensor 153 smaller than the distance between the fourth sensor 154 and the second sensor 152. The position that second sensor 152 set up is close to the downside more, has increased the threshold value of the too big condition of non-woven fabrics 21 tension in the non-woven fabrics unreeling device 1, reduces the shut-down number of times of non-woven fabrics unreeling device 1, makes non-woven fabrics unreeling device 1's work more stable.
