Technical Field

[0001] This utility model belongs to the field of nonwoven fabric shaping and pressing technology, and in particular relates to a folding roller type nonwoven fabric pressing device. Background Technology

[0002] When nonwoven fabrics leave the factory, they often require various types of pre-folding (pressing out creases, pressing out creases before folding, or folding directly) to meet the needs of specific applications and improve efficiency, hygiene, or convenience. Typically, nonwoven fabric is wound in rolls on a fabric reel, i.e., nonwoven fabric rolls. During folding, the free end of the nonwoven fabric roll is pulled out, and then the pulled-out nonwoven fabric is folded. Utility Model Content

[0003] This utility model provides a roller-type nonwoven fabric pressing and folding device, which can realize the continuous pressing and folding of nonwoven fabric. The pressing and folding form is alternating between upper and lower pressing, so as to automatically press out continuous, alternating creases. The whole process has a high degree of automation and good accuracy of pressing and folding position, which can facilitate subsequent folding of nonwoven fabric. In addition, the pressing and folding process is combined with the conveying process, with a high degree of structural integration and high overall efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A folding roller type nonwoven fabric pressing and folding device includes a main frame and two pressing and folding rollers that rotate in opposite directions, with one pressing and folding roller positioned above the other, and the pressing and folding rollers being rotatably connected to the main frame; The pressing roller is provided with a clamping groove, a number of pressing mechanisms and a number of fabric clamps provided in the clamping groove. The pressing mechanism on one pressing roller corresponds one-to-one with the fabric clamp on the other pressing roller. In the corresponding pressing mechanism and fabric clamp: the pressing mechanism includes a pressing groove on the pressing roller, a pressing plate in the pressing groove, and a pressing cylinder for driving the pressing plate to extend out of the pressing groove; the fabric clamp includes a clamping fixed part and a clamping moving part that can contact or separate from the clamping fixed part; when the clamping moving part is separated from the clamping fixed part, there is a fabric clamping space between the clamping moving part and the clamping fixed part. When one of the pressing mechanisms on the upper pressing roller rotates to its lowest position, the fabric clamp corresponding to that pressing mechanism is directly below it. When a pressing mechanism on the lower pressing roller rotates to its highest position, the corresponding fabric clamp is directly above the pressing mechanism.

[0005] Preferably, on a folding roller: both ends of the folding roller are provided with round end plates arranged coaxially with the folding roller and fixed to the main frame. The round end plates are provided with circumferential guide grooves opening on the end face of the round end plates. The fabric clamp also includes a clamp shaft parallel to the axis of the folding roller. The clamp moving part is provided on the clamp shaft. The clamp shaft is rotatably connected to the folding roller. Both ends of the clamp shaft are provided with connecting blocks. The connecting blocks are provided with end shafts that correspond one-to-one with the round end plates and are parallel to the clamp shaft. In the corresponding end shaft and round end plate: the circumferential guide groove includes a first arc groove, a second arc groove, a third arc groove and a fourth arc groove arranged sequentially along the circumference of the round end plate. The first arc groove connects to the second arc groove, the second arc groove connects to the third arc groove, the third arc groove connects to the fourth arc groove, and the fourth arc groove connects to the first arc groove. One end of the end shaft is provided with a bearing that can move along the circumferential guide groove. The first arc groove and the third arc groove are arranged symmetrically along the center of the pressure roller axis. The second arc groove and the fourth arc groove are arranged symmetrically along the center of the pressure roller axis. The distance between the second arc groove and the pressure roller axis is greater than the distance between the first arc groove and the pressure roller axis. When the bearing is in the first arc groove, the moving part of the clamp contacts the fixed part of the clamp.

[0006] Preferably, on a pleating roller: the clamping fixed component includes multiple fixed blocks arranged evenly along the axial direction of the pleating roller, and the clamping movable component includes multiple clamping plates corresponding to the fixed blocks one by one. The clamping plates are mounted on the clamping shaft through a ring seat, and the ring seat is sleeved on the clamping shaft. When the clamping movable component contacts the clamping fixed component, the clamping plate contacts the corresponding fixed block. When the clamping movable component separates from the clamping fixed component, the clamping plate separates from the corresponding fixed block, and a fabric clamping gap is formed between the clamping plate and the corresponding fixed block.

[0007] Preferably, on a pressing roller: the pressing plate includes a pressing base plate driven by a pressing cylinder and a plurality of pressing strips disposed on the pressing base plate. The pressing strips are provided with a pointed plate at one end away from the axis of the pressing roller for extending into the clamping space. The pointed plates are arranged sequentially along the axial direction of the pressing roller.

[0008] Preferably, there are two pressing mechanisms on one pressing roller and two fabric clamps on one pressing roller. On one pressing roller, one pressing mechanism, one fabric clamp, another pressing mechanism and another fabric clamp are arranged sequentially along the circumference of the pressing roller.

[0009] The beneficial effects of this utility model are: it can realize the continuous pressing and folding of non-woven fabric, and the pressing and folding form is alternating between upward and downward pressing, thereby automatically pressing out continuous, alternating creases. The whole process has a high degree of automation and good accuracy in pressing and folding position, which facilitates subsequent folding of non-woven fabric. In addition, the pressing and folding process is combined with the conveying process, with a high degree of structural integration and high overall efficiency. During the crease pressing process, the fabric clamp will automatically open and close at the required position, with accurate positioning and a high degree of automation. After the crease pressing operation is completed, the fabric clamp will assist in conveying the non-woven fabric forward a short distance and at the same time consolidate the crease.

Detailed Implementation

[0012] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0013] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, A folding roller type nonwoven fabric pressing and folding device includes a main frame and two pressing and folding rollers 1 that rotate in opposite directions, with one pressing and folding roller 1 positioned above the other pressing and folding roller 1, and the pressing and folding roller 1 being rotatably connected to the main frame; The pressing roller 1 is provided with a clamping groove 1.1, a number of pressing mechanisms and a number of fabric clamps provided in the clamping groove 1.1. The pressing mechanism on one pressing roller 1 corresponds one-to-one with the fabric clamp on another pressing roller 1. In the corresponding pressing mechanism and fabric clamp: the pressing mechanism includes a pressing groove 2.1 provided on the pressing roller 1, a pressing plate 201 provided in the pressing groove 2.1, and a pressing cylinder 202 for driving the pressing plate 201 to extend out of the pressing groove 2.1. The fabric clamp includes a clamp fixed member 301 and a clamp moving member 302 that can contact or separate from the clamp fixed member 301. When the clamp moving member 302 separates from the clamp fixed member 301, there is a fabric clamping space between the clamp moving member 302 and the clamp fixed member 301. When one of the pressing mechanisms on the upper pressing roller 1 rotates to the lowest position, the fabric clamp corresponding to the pressing mechanism is directly below the pressing mechanism. When one of the pressing mechanisms on the lower pressing roller 1 rotates to its highest position, the fabric clamp corresponding to that pressing mechanism is directly above it.

[0014] Before pressing and folding, the operator pulls out the free end of the nonwoven fabric roll and lets the nonwoven fabric pass between the two pressing rollers 1 (the nonwoven fabric between the two pressing rollers 1 is flat and without wrinkles). Since the two pressing rollers 1 turn in opposite directions, the nonwoven fabric can be continuously conveyed forward when the pressing rollers 1 rotate (the nonwoven fabric roll also rotates continuously to continuously release and supply nonwoven fabric).

[0015] When one of the pressing mechanisms on the upper pressing roller 1 rotates to its lowest position, the corresponding fabric clamp is in the open state (the clamp moving part 302 is separated from the clamp fixed part 301). The fabric clamp is directly below the pressing mechanism. The pressing cylinder 202 drives the pressing plate 201 to extend downward into the pressing groove 2.1 and presses the pressing plate 201 into the space between the clamp moving part 302 and the clamp fixed part 301 of the lower fabric clamp, thereby pressing a downward crease into the nonwoven fabric. Then the pressing mechanism resets, and the fabric clamp is switched to the closed state (clamped state). The fabric clamp continues to rotate a short distance while holding the nonwoven fabric, and then releases the nonwoven fabric. This not only assists in the forward feeding of the nonwoven fabric, but also consolidates the crease. The two pressing rollers 1 continue to feed the nonwoven fabric forward.

[0016] Subsequently, a pressing mechanism on the lower pressing roller 1 rotates to its highest position. At this time, the fabric clamp corresponding to the pressing mechanism is in the open state (the clamp moving part 302 is separated from the clamp fixed part 301). The fabric clamp is directly above the pressing mechanism. The pressing cylinder 202 drives the pressing plate 201 to extend upward into the pressing groove 2.1 and presses the pressing plate 201 into the space between the clamp moving part 302 and the clamp fixed part 301 of the upper fabric clamp, thereby pressing an upward crease into the nonwoven fabric. Then the pressing mechanism resets, and the fabric clamp is switched to the closed state (clamped state). The fabric clamp continues to rotate a short distance while holding the nonwoven fabric, and then releases the nonwoven fabric. This not only assists in forward conveying of the nonwoven fabric, but also consolidates the crease. The two pressing rollers 1 continue to convey the nonwoven fabric forward.

[0017] In this manner, the nonwoven fabric is alternately pressed up and down, resulting in continuous, alternating creases on the fabric. Throughout the process, except for the initial manual operation, the entire process is automated. The pressing roller 1 and related structures serve both to transport the nonwoven fabric and to press and fold it, resulting in high efficiency and excellent performance.

[0018] On a pleating roller 1: both ends of the pleating roller 1 are provided with round end plates 4 arranged coaxially with the pleating roller 1 and fixed to the main frame. The round end plates 4 are provided with circumferential guide grooves 4.1 that open on the end face of the round end plates. The fabric clamp also includes a clamp shaft 303 parallel to the axis of the pleating roller 1. The clamp moving part 302 is provided on the clamp shaft 303. The clamp shaft 303 is rotatably connected to the pleating roller 1. Both ends of the clamp shaft 303 are provided with connecting blocks 5. The connecting blocks 5 are provided with end shafts 501 that correspond one-to-one with the round end plates 4 and are parallel to the clamp shaft 303. In the corresponding end shaft 501 and round end plate 4: the circumferential guide groove 4.1 includes a first arc groove 4.1a, a second arc groove 4.1b, a third arc groove 4.1c, and a fourth arc groove 4.1d arranged sequentially along the circumference of the round end plate 4. The first arc groove 4.1a connects to the second arc groove 4.1b, the second arc groove 4.1b connects to the third arc groove 4.1c, the third arc groove 4.1c connects to the fourth arc groove 4.1d, and the fourth arc groove 4.1d connects to the first arc groove 4.1a. End shaft 501... The end is provided with a bearing 502 that can move along the circumferential guide groove 4.1. The first arc groove 4.1a and the third arc groove 4.1c are arranged symmetrically along the axis of the pressure roller 1. The second arc groove 4.1b and the fourth arc groove 4.1d are arranged symmetrically along the axis of the pressure roller 1. The distance between the second arc groove 4.1b and the axis of the pressure roller 1 is greater than the distance between the first arc groove 4.1a and the axis of the pressure roller 1. When the bearing 502 is in the first arc groove 4.1a, the clamp moving part 302 contacts the clamp fixed part 301.

[0019] On a folding roller 1: the axis of the clamp shaft 303 is separated from the axis of the folding roller 1.

[0020] Definition: On a pressure roller 1: the connecting block 5, the end shaft 501, and the bearing 502 on the end shaft 501 are all provided on a clamp shaft 303, and they all correspond to the clamp moving part 302 provided on the clamp shaft 303.

[0021] On a pleating roller 1: the fabric clamp rotates together with the pleating roller 1. In the corresponding clamp moving part 302 and bearing 502: when the bearing 502 is in the first arc groove 4.1a, the clamp moving part 302 contacts the clamp stationary part 301, and the clamp is in a closed state. When the bearing 502 moves from the first arc groove 4.1a into the second arc groove 4.1b, the fabric clamp is in an open state (the distance between the second arc groove 4.1b and the axis of the pleating roller 1 is greater than the distance between the first arc groove 4.1a and the axis of the pleating roller 1), that is, connected to the bearing 502... The position of the end shaft 501 relative to the pressure roller 1 changes, causing the end shaft 501 to drive the connecting block 5 and the clamp shaft 303 to rotate. Therefore, the clamp shaft 303 drives the corresponding clamp moving part 302 to move, thus opening the corresponding fabric clamp. Naturally, the pressing mechanism corresponding to the fabric clamp will then operate, pressing a portion of the nonwoven fabric into the clamping space. Subsequently, the clamp shaft 303 continues to rotate along with the pressure roller 1 where the clamp shaft 303 is located, and the bearing 502 enters the third... At this point, the fabric clamp returns to the closed state (the first arc groove 4.1a and the third arc groove 4.1c are symmetrically arranged along the axis of the pleating roller 1, and the second arc groove 4.1b and the fourth arc groove 4.1d are symmetrically arranged along the axis of the pleating roller 1; the distance between the second arc groove 4.1b and the axis of the pleating roller 1 is greater than the distance between the first arc groove 4.1a and the axis of the pleating roller 1). That is, the end shaft 501 will drive the connecting block 5 and the clamp shaft 303 to rotate. Therefore, the clamp shaft 303 will drive... The corresponding clamp actuator 302 moves, thereby closing the corresponding fabric clamp. As the pleating roller 1 continues to rotate, the nonwoven fabric is carried by the fabric clamp for a short distance. Then, the bearing 502 enters the fourth arc groove 4.1d, at which point the fabric clamp is in the open state. That is, the end shaft 501 drives the connecting block 5 and the clamp shaft 303 to rotate. Therefore, the clamp shaft 303 drives the corresponding clamp actuator 302 to move, thereby opening the corresponding fabric clamp and releasing the nonwoven fabric. This process can be repeated continuously for up-and-down pleating (crease) operations. The fabric clamp can automatically switch between open and closed states as the pleating roller 1 rotates, and the open and closed positions can be directly determined based on the positions of the first arc groove 4.1a, the second arc groove 4.1b, the third arc groove 4.1c, and the fourth arc groove 4.1d, which also facilitates accurate positioning.

[0022] Summary: When one of the clamping clips on the upper folding roller 1 rotates to its lowest position, or when one of the clamping clips on the lower folding roller 1 rotates to its highest position, the clamping clips are in the open state in this section. This allows them to adapt to the upper or lower pressing plate 201, thus smoothly folding the nonwoven fabric. Afterward, the clamping clips continue to advance forward (as the folding roller 1 rotates) a short distance with the folded nonwoven fabric in this section. Then, the clamping clips open, the nonwoven fabric is released, and the indentation is reinforced.

[0023] On a pleating roller 1: the clamping member 301 includes a plurality of fixing blocks 301.1 arranged sequentially and evenly along the axial direction of the pleating roller 1; the clamping member 302 includes a plurality of clamping plates 302.1 corresponding one-to-one with the fixing blocks 301.1; the clamping plates 302.1 are mounted on the clamping shaft 303 via ring seats 302.2; the ring seats 302.2 are sleeved on the clamping shaft 303; when the clamping member 302 contacts the clamping member 301, the clamping plates 302.1 contact the corresponding fixing blocks 301.1; when the clamping member 302 separates from the clamping member 301, the clamping plates 302.1 separate from the corresponding fixing blocks 301.1; and a fabric clamping gap 302a is formed between the clamping plates 302.1 and the corresponding fixing blocks 301.1.

[0024] The clamp 302.1 is fixed by using a ring sleeve. The clamp 302.1 and the fixing block 301.1 correspond one-to-one, which can better cooperate with each other and ensure the smooth pressing (indentation) operation.

[0025] On a pressing roller 1: the pressing plate 201 includes a pressing base plate 201.1 driven by a pressing cylinder 202 and a plurality of pressing strips 201.2 disposed on the pressing base plate 201.1. The pressing strip 201.2 is provided with a pointed plate 201.3 for extending into the fabric clamping space at one end away from the axis of the pressing roller 1. Each pointed plate 201.3 is arranged sequentially along the axis of the pressing roller 1.

[0026] The pointed board 201.3 is easier to enter the fabric clamping space, and the pointed board 201.3 has a stronger effect in pressing out indentations.

[0027] There are two pressing mechanisms on one pressing roller 1 and two fabric clamps on one pressing roller 1. On one pressing roller 1, one pressing mechanism, one fabric clamp, another pressing mechanism and another fabric clamp are arranged in sequence along the circumference of the pressing roller 1.

[0028] During operation, each rotation of the pressing roller 1 leaves four indentations on the nonwoven fabric (two upper indentations and two lower indentations).
