Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a nonwoven fabric roll slitting machine. Background Technology

[0002] In the production and processing of nonwoven fabrics, slitting is a crucial post-processing step. Its function is to cut the wide nonwoven fabric master roll into narrow rolls of specific widths according to requirements, to meet the specifications of downstream applications (such as medical protective equipment, hygiene products, and packaging materials). Traditional nonwoven fabric slitting machines typically employ a linear process of "unwinding—slitting—rewinding," where the nonwoven fabric raw material is released through an unwinding mechanism, cut by a slitting blade (such as a circular blade, straight blade, or ultrasonic blade), and then the finished product is wound up by a rewinding mechanism. However, this traditional slitting method has the following technical limitations: because the slitting process requires unwinding, slitting, and rewinding to be completed sequentially, the unwinding and rewinding speeds are limited, resulting in low slitting efficiency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a nonwoven fabric roll slitting machine that can efficiently slit nonwoven fabric rolls.

[0004] This utility model discloses a nonwoven fabric roll slitting machine, including a base. A first mounting seat is provided on the upper side of the base. A first rotating shaft and a second rotating shaft are parallel to each other and at the same height on the upper side of the first mounting seat. A first motor, which is driven and connected to the first rotating shaft, is mounted on the first mounting seat. An annular airbag is fitted and fixed on the second rotating shaft, and an inflation / deflation nozzle is provided on the side of the annular airbag. A set of slide rails is provided on the lower side of the base away from the second rotating shaft. The slide rails are perpendicular to the first rotating shaft. A slide block is slidably mounted on the slide rails. A straight blade is vertically mounted on the upper side of the slide block, perpendicular to the first rotating shaft with its blade facing the first rotating shaft. A second motor is mounted on the base. A lead screw is mounted on the shaft of the second motor. The lead screw is mounted on the base via a bearing seat and is parallel to the slide rail. A nut is provided on the slide block, and the lead screw and nut are driven and connected.

[0005] The principle of the above technical solution is as follows: a non-woven fabric roll is installed on a first rotating shaft. An annular airbag on a second rotating shaft inflates and presses against the non-woven fabric roll. A first motor drives the first rotating shaft to rotate, causing the non-woven fabric roll on it to rotate. It should be noted that the rotation direction of the first rotating shaft is opposite to the winding direction of the non-woven fabric on the roll. Therefore, as the first rotating shaft rotates, the non-woven fabric roll remains taut with the help of the annular airbag. During slitting, the second motor drives a slide block to move along a slide rail via a lead screw and nut, causing a straight blade to vertically cut the rotating roll of non-woven fabric, resulting in high cutting efficiency.

[0006] To more precisely control the movement distance of the straight blade, the second motor is a servo motor. The second motor is electrically connected to a controller, which precisely controls the rotation angle of the servo motor shaft, thereby precisely controlling the movement distance of the slide and the straight blade through the lead screw and nut.

[0007] To better secure the nonwoven fabric roll, a flange is provided at the end of the No. 1 rotating shaft near the No. 1 mounting base, and an external thread is provided on the side of the end of the No. 1 rotating shaft away from the No. 1 mounting base. It also includes a bushing with an internal thread on the inner side. The bushing is screwed to the No. 1 rotating shaft, and the nonwoven fabric roll on the No. 1 rotating shaft is secured by the flange and the bushing.

[0008] To facilitate the adjustment of the straight blade's position, a second mounting base is provided on the lower side of the straight blade. The second mounting base has a vertical through hole, and mounting holes are evenly distributed on the upper surface of the slide. The mounting holes are internally threaded. The second mounting base is fixed to the slide by bolts and mounting holes. The position of the straight blade is adjusted by installing the second mounting base on different mounting holes.

[0009] The nonwoven fabric roll slitting machine obtained by this utility model has the following advantages: after the annular airbag on the second rotating shaft is inflated and presses against the nonwoven fabric roll, the nonwoven fabric roll remains tight at all times with the cooperation of the annular airbag when the first rotating shaft rotates and drives the nonwoven fabric roll on it to rotate. During slitting, the second motor drives the slide block to move along the slide rail through the lead screw and nut, which drives the straight knife to vertically cut the rotating whole roll of nonwoven fabric, resulting in high cutting efficiency.

[0011] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0012] Example 1:

[0013] like Figure 1As shown, this utility model discloses a nonwoven fabric roll slitting machine, including a base 1. A first mounting seat 6 is provided on the upper side of the base 1. A first rotating shaft 11 and a second rotating shaft 8 are arranged on the upper side of the first mounting seat 6, which are parallel to each other and are at the same height. A first motor 9 is provided on the first mounting seat 6 and is connected to the first rotating shaft 11 for transmission. An annular airbag 7 is sleeved and fixed on the second rotating shaft 8. An inflation / deflation nozzle 13 is provided on the side of the annular airbag 7. The first rotating shaft 11 is away from the second rotating shaft. A set of slide rails 2 is provided on the lower base 1 on the side of 8. The slide rails 2 are perpendicular to the first rotating shaft 11. A slide block 18 is slidably mounted on the slide rails 2. A straight blade 12 is vertically mounted on the upper side of the slide block 18. The straight blade 12 is perpendicular to the first rotating shaft 11 and its blade is directly facing the first rotating shaft 11. A second motor 5 is provided on the base 1. A lead screw 4 is provided on the rotating shaft of the second motor 5. The lead screw 4 is mounted on the base 1 through a bearing seat. The lead screw 4 is parallel to the slide rails 2. A nut 3 is provided on the slide block 18. The lead screw 4 and the nut 3 are connected by a transmission.

[0014] The principle of the above technical solution is as follows: a non-woven fabric roll is installed on the first rotating shaft 11. The annular airbag 7 on the second rotating shaft 8 inflates and presses against the non-woven fabric roll. The first rotating shaft 11 is driven to rotate by the first motor 9, which in turn drives the non-woven fabric roll to rotate. It should be noted that the rotation direction of the first rotating shaft 11 is opposite to the winding direction of the non-woven fabric on the roll. Thus, when the first rotating shaft 11 rotates and drives the non-woven fabric roll to rotate, the non-woven fabric roll remains tight at all times with the cooperation of the annular airbag 7. During slitting, the second motor 5 drives the slide block 18 to move along the slide rail 2 through the lead screw 4 and nut 3, which drives the straight knife 12 to vertically cut the rotating whole roll of non-woven fabric, resulting in high cutting efficiency.

[0015] To more precisely control the movement distance of the straight blade 12, the second motor 5 is a servo motor. The second motor 5 is electrically connected to a controller. The controller precisely controls the rotation angle of the servo motor shaft, thereby precisely controlling the movement distance of the slide 18 and the straight blade 12 through the lead screw 4 and nut 3.

[0016] To better secure the nonwoven fabric roll, a flange 10 is provided at the end of the first rotating shaft 11 near the first mounting base 6, and an external thread is provided on the side of the end of the first rotating shaft 11 away from the first mounting base 6. It also includes a bushing 14 with an internal thread on the inner side. The bushing 14 is screwed to the first rotating shaft 11, and the nonwoven fabric roll on the first rotating shaft 11 is secured by the flange 10 and the bushing 14.

[0017] To facilitate the adjustment of the position of the straight blade 12, a second mounting base 16 is provided on the lower side of the straight blade 12. The second mounting base 16 has a vertical through hole. Mounting holes 17 are evenly provided on the upper surface of the slide block 18. The mounting holes 17 are provided with internal threads. The second mounting base 16 is fixed to the slide block 18 by bolts 15 and mounting holes 17. The position of the straight blade 12 can be adjusted by installing the second mounting base 16 on different mounting holes 17.
