Description

An adjustable nonwoven fabric folding machine Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, specifically to an adjustable nonwoven fabric folding machine. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth or non-woven textile, is a type of fabric that does not require spinning or weaving. It is not made through traditional spinning and weaving processes, but rather by directly bonding fibers together using physical methods. After production, non-woven fabric needs to be folded before packaging, thus requiring a non-woven fabric folding machine. However, current non-woven fabric folding machines still have the following shortcomings:

[0003] For example, patent application number 202020331942.9 discloses a nonwoven fabric folding machine. This nonwoven fabric folding machine can meet the requirements of automated folding of nonwoven fabrics, improve the flatness of folded nonwoven fabrics, reduce manual intervention, and reduce production costs. However, it is not convenient to adjust the spacing of the limiting structure of the nonwoven fabric, and it cannot be applied to folding nonwoven fabrics of different widths.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed an adjustable nonwoven fabric folding machine.

[0006] The purpose of this invention is to provide an adjustable nonwoven fabric folding machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable nonwoven fabric folding machine, comprising a fixed base and an adjusting assembly. A support platform is installed on the front side of the upper surface of the fixed base. The adjusting assembly is disposed on the surface of the support platform and includes a support plate, a servo motor, a bidirectional lead screw, a moving part, a limiting plate, a limiting groove, and a limiting slider. The support plate is disposed on the left and right sides of the support platform, and a servo motor is installed on the upper part of the left side surface of the support plate. The output end of the servo motor is connected to the bidirectional lead screw via a coupling, and a moving part is threadedly connected to the surface of the bidirectional lead screw. Two sets of moving parts are symmetrically arranged, and a limiting plate is installed on the lower surface of the moving parts. A limiting groove is formed on the upper surface of the support platform.

[0008] Furthermore, a limiting slider is slidably connected to the inner side of the limiting groove, and the upper surface of the limiting slider is connected to the lower surface of the limiting plate.

[0009] Furthermore, a limiting support roller is installed on the rear side of the upper surface of the fixed base, and a limiting component for limiting the nonwoven fabric is provided on the rear surface of the fixed base.

[0010] Furthermore, the limiting component includes a support member, a protective cover, and a rotating motor. The support member is disposed on the rear surface of the fixed base, and the protective cover is installed on the upper right surface of the support member. The rotating motor is disposed inside the protective cover.

[0011] Furthermore, the limiting assembly also includes a threaded screw, a limiting disc, and a limiting moving cylinder, and the output end of the rotating motor is connected to the threaded screw via a coupling. The right end of the threaded screw is equipped with a limiting disc, and the left end of the threaded screw is threadedly connected to the limiting moving cylinder.

[0012] Furthermore, a support frame is installed at the front end of the upper surface of the fixed base, and a fixed cover is installed on the upper surface of the support frame. A rotary motor is installed on the right side of the upper surface of the fixed cover, and the output end of the rotary motor is connected to a main gear through a coupling.

[0015] This utility model provides an adjustable nonwoven fabric folding machine, which has the following beneficial effects:

[0016] 1. This utility model incorporates an adjustment assembly, which includes a support plate, a servo motor, a bidirectional lead screw, moving parts, a limiting plate, a limiting groove, and a limiting slider. In use, the servo motor is activated, causing it to rotate the bidirectional lead screw. This, in turn, causes two sets of moving parts to move towards each other along the surface of the bidirectional lead screw. Furthermore, the moving parts drive the limiting plate to move inwards. During the movement of the limiting plate, the sliding connection between the limiting slider and the limiting groove limits its movement. This allows the device to adjust the limiting distance for non-woven fabrics, facilitating the limiting of folded non-woven fabrics of different widths.

[0017] 2. This utility model incorporates a limiting component, which includes a support, a protective cover, and a rotating motor. The limiting component also includes a threaded screw, a limiting disc, and a limiting moving cylinder. In use, the limiting moving cylinder is removed, and the non-woven fabric roll is fitted onto the threaded screw through its outer end. The limiting disc is rotated to adjust its position according to the width of the non-woven fabric roll and to limit the inner surface of the roll. The limiting moving cylinder is then threadedly connected to the threaded screw and moved until it is in contact with the outer surface of the non-woven fabric roll. The rotating motor is then started, causing the threaded screw to rotate as a whole. This allows the device to stably limit non-woven fabric rolls of different widths and achieve automatic unwinding. Simultaneously, it prevents the non-woven fabric roll from shifting during unwinding. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] As shown in Figures 1 to 4, an adjustable nonwoven fabric folding machine includes a fixed base 1 and an adjusting component 3. A support platform 2 is installed on the front side of the upper surface of the fixed base 1. The adjusting component 3 is disposed on the surface of the support platform 2 and includes a support plate 301, a servo motor 302, a bidirectional lead screw 303, a moving part 304, a limiting plate 305, a limiting groove 306, and a limiting slider 307. The support plate 301 is disposed on the left and right sides of the support platform 2. A servo motor 302 is installed on the upper part of the left side surface of the support plate 301. The output end of the servo motor 302 is connected to the bidirectional lead screw 303 through a coupling. A moving part 304 is threadedly connected to the surface of the bidirectional lead screw 303. Two sets of moving parts 304 are symmetrically arranged. A limiting plate 305 is installed on the lower surface of the moving part 304. A limiting groove 306 is opened on the upper surface of the support platform 2.

[0025] The specific operation is as follows: When in use, start the servo motor 302, so that the servo motor 302 drives the bidirectional lead screw 303 to rotate, which in turn drives the two sets of moving parts 304 to move towards each other along the surface of the bidirectional lead screw 303. Furthermore, the moving parts 304 drive the limiting plate 305 to move inward. During the movement of the limiting plate 305, the movement of the limiting plate 305 is limited by the sliding connection between the limiting slider 307 and the limiting groove 306.

[0026] Please refer to Figure 3. A limiting slider 307 is slidably connected to the inner side of the limiting groove 306, and the upper surface of the limiting slider 307 is connected to the lower surface of the limiting plate 305. A limiting support roller 4 is installed on the rear side of the upper surface of the fixed base 1, and a limiting component 5 for limiting the non-woven fabric is provided on the rear surface of the fixed base 1. The limiting component 5 includes a support member 501, a protective cover 502 and a rotating motor 503. The support member 501 is located on the rear surface of the fixed base 1. The protective cover 502 is installed on the upper right side of the support member 501, and the rotating motor 503 is provided inside the protective cover 502. The limiting component 5 also includes a threaded screw 504, a limiting plate 505 and a limiting moving cylinder 506. The output end of the rotating motor 503 is connected to the threaded screw 504 through a coupling. The limiting plate 505 is installed on the right end of the threaded screw 504, and the limiting moving cylinder 506 is threadedly connected to the left end of the threaded screw 504.

[0027] The specific operation is as follows: When in use, remove the limiting moving cylinder 506, and put the non-woven fabric roll on the threaded screw 504 through the outer end of the threaded screw 504. Rotate the limiting plate 505 to adjust its position according to the width of the non-woven fabric roll and limit the inner surface of the non-woven fabric roll. Then, thread the limiting moving cylinder 506 to the threaded screw 504 and move it to fit against the outer surface of the non-woven fabric roll to prevent the non-woven fabric roll from moving during the unwinding process. Start the rotating motor 503 to drive the threaded screw 504 to rotate as a whole, thereby driving the non-woven fabric roll fixed on the threaded screw 504 to automatically unwind.

[0028] Please refer to Figures 1 and 4. A support frame 6 is installed on the front end of the upper surface of the fixed base 1, and a fixed cover 7 is installed on the upper surface of the support frame 6. A rotary motor 8 is installed on the right side of the upper surface of the fixed cover 7, and the output end of the rotary motor 8 is connected to a main gear 9 through a coupling. A secondary gear 10 is meshed on the left side of the main gear 9. A folding auxiliary roller 11 is installed on the lower surface of the main gear 9 and the secondary gear 10. A connecting plate 12 is installed on the rear side of the upper end of the support frame 6, and an electric push rod 13 is provided on the upper surface of the connecting plate 12. A limit piece 14 is installed at the bottom of the electric push rod 13. A support seat 15 is installed on the front surface of the fixed base 1, and a support frame 16 is provided on the upper surface of the support seat 15. A hydraulic push rod 17 is installed on the inner side of the upper end of the support frame 16, and a cutting blade 18 is provided at the bottom of the hydraulic push rod 17.

[0029] [Revised according to Rule 26, August 2021] The specific operation is as follows: When using, the nonwoven fabric roll passes around the limiting support roller 4 during unwinding. The electric push rod 13 is started, which drives the limiting member 14 to move downward. During the unwinding process, the nonwoven fabric is supported by the limiting support roller, and its position is relatively fixed. The limiting member 14 pushes the middle part of the nonwoven fabric downward, thereby creating a fold. At the same time, the rotary motor 8 is started, which drives the secondary gear 10 to rotate through the main gear 9, thereby driving the two sets of folding auxiliary rollers 11 to rotate in opposite directions, squeezing the folded nonwoven fabric and folding it on the support platform 2. At the same time, the hydraulic push rod 17 drives the cutting blade 18 to move downward. The folded nonwoven fabric is pushed forward automatically by the nonwoven fabric behind it, thereby cutting the folded nonwoven fabric through the cutting blade 18.

[0030] [Revised according to Rule 26, August 2024] In summary, as shown in Figures 1 to 4, when using this adjustable nonwoven fabric folding machine, firstly, remove the limiting moving cylinder 506, and place the nonwoven fabric roll onto the threaded screw 504 through the outer end of the threaded screw 504. Rotate the limiting plate 505 to adjust its position according to the width of the nonwoven fabric roll and limit the inner surface of the nonwoven fabric roll. Then, thread the limiting moving cylinder 506 to the threaded screw 504 and move it to fit against the outer surface of the nonwoven fabric roll to prevent the nonwoven fabric roll from moving during unwinding. Subsequently, start the servo motor 302, which drives the bidirectional screw 303 to rotate, thereby driving the two sets of moving parts 304 to move towards each other along the surface of the bidirectional screw 303. Further, the moving parts 304 drive the limiting plate 305 to move inward. Adjust the spacing of the limiting plate 305 according to the size of the nonwoven fabric folding. The adjustment is then complete. Then, the rotary motor 503 is started, causing the rotary motor 503 to drive the threaded screw 504 to rotate as a whole, thereby driving the nonwoven fabric roll fixed on the threaded screw 504 to automatically unwind. During unwinding, the nonwoven fabric roll passes around the limiting support roller 4. The electric push rod 13 is started, causing the electric push rod 13 to drive the limiting member 14 to move downward. During the unwinding process, the nonwoven fabric is relatively fixed in position due to the support of the limiting support roller. The limiting member 14 pushes the middle part of the nonwoven fabric downward, thereby creating a fold. At the same time, the rotary motor 8 is started, causing the rotary motor 8 to drive the secondary gear 10 to rotate through the main gear 9, thereby driving the two sets of folding auxiliary rollers 11 to rotate in opposite directions, squeezing the folded nonwoven fabric, causing the nonwoven fabric to fold on the support platform 2. At the same time, the hydraulic push rod 17 drives the cutting blade 18 to move downward. The folded nonwoven fabric is pushed forward automatically by the nonwoven fabric behind it, thereby cutting the folded nonwoven fabric through the cutting blade 18.
