Description

Technical Field

[0001] This invention relates to the technical field of nonwoven machinery, and more specifically to a winding machine suitable for a hydroentangled nonwoven fabric production line. Background Technology

[0002] Nonwoven fabrics, due to their short processing flow, low investment, quick returns, and small footprint, are gaining an increasingly larger market share. Market demand for nonwoven fabric products has driven the development of nonwoven fabric machinery. In the continuous production process, the nonwoven fabric produced in the previous process needs to be slit and wound by a winding machine to become a roll of nonwoven fabric with a certain shape. After post-processing such as humidification, heating, and setting, it becomes an industrial finished product with good elasticity, toughness, and flexibility. The gradual improvement in the quality of nonwoven fabrics and the continuous increase in the speed of nonwoven equipment have spurred the rapid development of nonwoven fabric winding machines.

[0003] The winding machine in a nonwoven spunlace production line is the equipment used to wind pre-shaped nonwoven fabrics to a fixed width and length. It is one of the machines with the most mechanisms and the most complex movements in the nonwoven spunlace production line. The nonwoven spunlace production line is a highly efficient continuous operating system; however, currently, the winding machine does not have an automatic roll-changing function, resulting in low working efficiency and a low degree of automation. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a winding machine suitable for nonwoven hydroentangled fabric production lines. The winding machine of the present invention can store multiple fabric winding shafts in advance, and the fabric winding shafts are fully automated from the storage station to the production station. The machine can maintain the style of the fabric surface and ensure the continuity of production under high-speed production.

An expansion sleeve is sleeved on the spring clip. An expansion sleeve pressure plate is located on the left side of the expansion sleeve. The expansion sleeve pressure plate is connected to the clamping seat by bolts. Under the tension of the bolts, the expansion sleeve pressure plate presses the expansion sleeve, and the expansion of the expansion sleeve causes the spring clip to be clamped on the power output shaft.

[0022] The beneficial effects of this invention are:

[0023] 1. This winding machine can reserve multiple fabric rolls in advance. The fabric rolls are fully automated from the reserve station to the production station, maintaining the style of the fabric and ensuring the continuity of production under high-speed production conditions.

[0024] 2. This winding machine is equipped with a pre-acceleration station. Before winding the fabric, the spare fabric winding shaft will be pre-accelerated at the pre-acceleration station, which ensures that it has the same speed as the main winding shaft when winding the fabric, thus eliminating the phenomenon of initial fabric roll slack caused by the speed mismatch of the fabric winding shaft.

A seventh sprocket 64 is provided on the fourth synchronous shaft 63, corresponding one-to-one with the two eighth sprockets 62. A synchronous chain 65 is provided between the seventh sprocket 64 and the corresponding eighth sprocket 62. The lower end of the push plate 611 is connected to the synchronous chain 65 located on the same side.

[0071] In one specific implementation, the push plate 611 in this embodiment has two protrusions symmetrically arranged on the left and right sides of its lower end. The synchronization chain 65 is an open-loop chain, and the two ends of the synchronization chain 65 are respectively connected to the protrusions by screws.

[0072] Furthermore, such as Figure 5 As shown, a second roller 618 is provided at the lower end of the first stop arm 613, and in the free state, the second roller 618 is pressed against the left side of the push plate 611 under the tension of the first tension spring 615.

[0073] Furthermore, such as Figure 5 As shown, the upper ends of the first stop arm 613 and the second stop arm 614 are respectively provided with a third roller 619 for abutting against the cloth rolling shaft.

[0074] Furthermore, such as Figure 5 As shown, the upper end of the push plate 611 is provided with a bayonet 6111, and the first stop arm 613 and the second stop arm 614 are respectively located on both sides of the bayonet 6111.

[0075] Furthermore, the second stop arm 614 has an angular structure with its opening facing the first stop arm 613, and the first roller 617 is located at the corner of the second stop arm 614.

[0076] like Figure 1 and Figure 2As shown, a secondary rolling device is provided on the outer side of each of the two upright plates. The secondary rolling device includes a rolling arm 71 hinged to the outer surface of the upright plate, with the middle portion of the rolling arm 71 hinged to the upright plate. A second rolling cylinder 72 is provided between the upright plate and the rolling arm 71 to drive the rolling arm 71 to swing. The cylinder body of the second rolling cylinder 72 is hinged to the upright plate, and the piston rod end of the second rolling cylinder 72 is hinged to the rolling arm 71. When the piston rod of the second rolling cylinder 72 is extended, the right end of the rolling arm 71 is located above the third side plate 113 of the upright plate; when the piston rod of the second rolling cylinder 72 is retracted, the right end of the rolling arm 71 is located below the third side plate 113 of the upright plate.

[0077] Preferably, the push-coil arm 71 has a triangular structure, a fourth roller 73 is provided at the left end of the push-coil arm 71, a third stop arm 711 is provided at the right end of the push-coil arm 71, and the third stop arm 711 is in a vertical state when the piston rod of the second push-coil cylinder 72 is in the extended state.

[0078] Furthermore, such as Figure 1 , Figure 15 As shown, stop components 8 for preventing the fabric roll shaft from reversing are provided on both the left and right sides of the third stop arm 711 on the upright plate. The stop components 8 include a thrust plate 81 disposed on the outer side of the upright plate, and the thrust plate 81 is hinged to the upright plate via a hinge shaft 82. The left side of the thrust plate 81 is an inclined surface sloping upwards to the right, and the right side of the thrust plate 81 is a vertical surface with a clearance notch 811 on the right side. The thrust plate 81 extends above the upright plate, and a first hanging shaft 812 is disposed on the thrust plate 81 below the hinge shaft 82. A fixing block 83 is disposed on the right side of the thrust plate 81, and the fixing block 83 restricts the rotation of the thrust plate 81 to the left. Due to the presence of the clearance notch 811, when the thrust plate 81 rotates to the right, the fixing block 83 does not obstruct the thrust plate 81. The lower end of the fixing block 83 is provided with a second hanging shaft 831, and a second tension spring 84 is connected between the first hanging shaft 831 and the second hanging shaft 812. When the fabric roll is transported to this position by the primary push-winding device, the thrust plate 81 moves clockwise under the push of the fabric roll. After the fabric roll passes, the thrust plate 81 returns to its original position due to the action of the second tension spring 84. Due to the obstruction of the fixing block 83, the thrust plate is prevented from continuing to move counterclockwise after returning to its original position. The purpose of this design is to prevent the fabric located at the secondary push-winding position from moving in the opposite direction.

[0079] Furthermore, to ensure that the spare fabric roll has the same rotational speed as the active winding device during fabric winding, and to eliminate the initial fabric roll slack caused by speed mismatch of the fabric roll, a pre-acceleration station is provided between the conveying device and the winding station, and a pre-acceleration device is provided at the pre-acceleration station. Figure 8 As shown, the pre-acceleration device includes a pre-acceleration motor 91 mounted on the front upright plate. The pre-acceleration motor 91 is located on one side inside the second side plate 112 (with the opposite side of the two second side plates as the inside). The pre-acceleration motor 91 is connected to a reducer (not shown in the figure). A friction wheel 92 is mounted on the power output shaft of the reducer. A connecting plate is mounted below the reducer. A connecting block is mounted on the connecting plate. The connecting block is rotatably connected to the piston rod end of the first cylinder 93. The first cylinder 93 is hinged to a cylinder support 94 fixed inside the upright plate. A swing arm 95 is fixedly connected below the reducer. The other end of the swing arm 95 is hinged to a connecting piece on a swing arm support plate 96 fixed inside the upright plate.

[0080] Furthermore, in order to secure the spare fabric roll placed at the pre-acceleration station, such as... Figure 2 , Figure 3 and Figure 7 As shown, a limiting arm 97 is provided on the rear upright plate. The limiting arm 97 is located on the inner side of the upright plate (with the opposite side of the two second side plates as the inner side). The limiting arm 97 has an arc-shaped structure, and one end of the limiting arm 97 is hinged to the upright plate. The middle part of the limiting arm 97 is hinged to the piston rod of the second cylinder 98. The cylinder body of the second cylinder 98 is hinged to the connector fixed on the upright plate.

[0081] Furthermore, a tension detection device is provided below the pre-acceleration station. The tension detection device includes a tension sensor (not shown in the figure) and a guide roller 23. Bearings are provided at both ends of the guide roller 23. The bearing supports are fixedly connected to the tension sensor. The tension sensor is fixedly connected to the frame 1 by screws. The tension sensor can detect the tension of the fabric. Then, based on the detection value of the tension sensor, the speed of the main winding roller is adjusted to prevent the fabric from being wound too loosely or too tightly.

[0082] The basic principle of this invention is as follows:

[0083] Before receiving the spunlace fabric from the machine in the previous process, the fabric roll is placed on the support platform 15 of the spare roll storage and conveying device. Then, the second reduction motor 48 drives the first synchronous shaft 46 to rotate. Through the cooperation of the first sprocket 45 and the second sprocket 47, the first sprocket 45 drives the second gear 44 to rotate through the transmission shaft. The second gear 44 meshes with the first gear 43, causing the support shaft 41 and the transfer arm 42 to rotate counterclockwise, so that the groove of the transfer arm 42 contacts the spare fabric roll 3. At this time, the second reduction motor 48 drives the support shaft 41 and the transfer arm 42 to rotate clockwise, placing the spare fabric roll 3 into the pre-acceleration station.

[0084] Next, the second cylinder 98 drives the limiting arm 97 to rise, and the limiting arm 97 restricts the fabric roll shaft 3 in the pre-acceleration station. At this time, the piston rod of the positioning cylinder 544 in the flipping robot arm extends, thereby driving the clamping part 5431 of the sliding plate 543 to move to the pre-acceleration station. The clamping wheels 545 at both ends of the clamping notch 5432 abut against the fabric roll shaft 3. The locking arm 546 rotates under the action of the locking cylinder 547 until the clamping wheel 545 on the locking arm 546 abuts against the fabric roll shaft, thereby clamping and gripping the fabric roll shaft 3. The first cylinder 93 drives the reducer on the pre-acceleration motor 91 to rise, so that the friction wheel 92 on the reducer is tangent to the fabric roll shaft 3, ensuring that the fabric roll shaft 3 in the pre-acceleration station reaches the predetermined rotation speed. After the pre-acceleration is completed, the first cylinder 93 drives the reducer to descend to the initial position. At the same time, the piston rod of the second cylinder 98 retracts, driving the limiting arm 97 to descend.

[0085] Finally, the piston rod of the positioning cylinder 544 in the shifting component retracts, thereby sending the accelerated fabric roll 3 to the left side of the active winding shaft 51. At this time, the outer surface of the fabric roll 3 contacts the outer surface of the active winding shaft 51, and the fabric roll 3 and the active winding shaft 51 rotate synchronously.

[0086] After completing the above actions, the spunlace fabric from the previous process is received. The spunlace fabric first passes through the first guide roller 21 to the second guide roller 22, and then to the tension detection device. It then begins to wind onto the roll shaft. When the roll thickness reaches 150mm-200mm, the flipping robotic arm, driven by the fifth reduction motor 549, rotates clockwise around the active winding shaft 51, thereby moving the roll shaft 3 from the left side to the right side of the active winding shaft 51. Then, the first pusher in the pusher device... The piston rod of the air cylinder 612 retracts, causing the push plate 611 to carry the first stop arm 613 and the second stop arm 614 to move to the left along the linear guide rail. When the outer surface of the third roller 619 on the first stop arm 613 contacts the outer surface of the cloth winding shaft 3 on the right side of the active winding shaft 51, the third roller 619 drives the first stop arm 613 to rotate clockwise, so that the cloth winding shaft 3 enters the slot 6111 located in the primary push-winding device. At the same time, the first stop arm 613 rotates counterclockwise to return to its original position under the tension of the first tension spring 615. In the first push-roll device, the first push-roll cylinder 612 is in the retracted state. Under the leftward pull of the first push-roll cylinder 612, the outer surface of the fabric roll is kept in contact with the outer surface of the main winding shaft. Then, the piston of the locking cylinder 547 on the flipping robotic arm retracts, thereby driving the locking arm 546 to release the locking of the fabric roll shaft 3. Then, the fifth reduction motor 549 drives the flipping robotic arm to rotate counterclockwise around the active winding shaft 51 and return to the initial position. When the fabric roll on the roll shaft reaches the set length, the cross-cutting component 53, driven by the fourth reduction motor 533 and supported by the support arm 5311, rotates clockwise around the active winding shaft 51 to reach the working position. At the same time, a new spare fabric roll shaft 3 arrives at the left side of the active winding shaft 51 via the conveying device and the pre-acceleration device. Then, the rodless cylinder 535 in the cross-cutting component 53 drives the pneumatic motor mounting base 5352 to move. The cutting blade 5372 moves with the pneumatic motor mounting base 5352, cutting the spunlace fabric and blowing the cut spunlace fabric through the air passage onto a new roll shaft located to the left of the active winding shaft. At this time, the new roll shaft begins to wind. Then, the piston rod of the first push-winding cylinder 612 in the first push-winding device extends, driving the push plate 611 to carry the roll shaft to the right along the linear guide rail. After the roll shaft is pushed away, the cross-cutting component 53 returns to its initial position through the support arm 5311 driven by the fourth reduction motor 533.During the pushing process of the first pushing cylinder 612, the first roller 617 on the second stop arm 614 moves to the right along the guide plate 616. When the first roller 617 moves to the arc-shaped part at the right end of the guide plate 616, the second stop arm 614 moves downward along the arc-shaped part of the guide plate 616 under its own gravity, gradually becoming horizontal, and thus gradually releasing the restriction on the fabric roll shaft. When the second stop arm 614 completely releases the restriction on the fabric roll shaft, the rolled fabric can be conveyed to the secondary pushing device, and then... In the push-winding device, the push plate 611 moves to the left under the action of the first push-winding cylinder 612 until the fabric roll 3 located on the right side of the active winding shaft 51 enters the latch 6111 in the primary push-winding device. When the push plate 611 moves to the left, the first roller 617 on the second stop arm 614 moves along the arc-shaped part of the guide plate 616 to the straight part. At this time, the second stop arm 614 changes from a horizontal state to a vertical state under the restriction of the first roller 617 and the guide plate 616, thereby achieving the restriction of the fabric roll 3. When the first push-winding cylinder 612 moves to the left, the piston rod of the second push-winding cylinder 72 in the secondary push-winding device retracts, driving the push-winding arm 71 to rotate around the bearing, thereby conveying the finished fabric roll to the finished fabric roll storage area. The fabric roll in the finished fabric roll storage area is lifted away by the customer. This process is repeated to achieve continuous production.
