Description

Technical Field

[0001] The invention relates to the technical field of nonwoven fabric production, in particular to a traction and stretching mechanism for nonwoven fabric forming equipment. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is a fabric that does not require spinning and weaving. It is made by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, without warp and weft, very convenient to cut and sew, and light and easy to shape, and is deeply loved by handicraft enthusiasts. Non-woven fabrics need to be kept stretched during the production process to prevent wrinkles from appearing during the subsequent rolling process.

[0012] (1) The traction and stretching mechanism for non-woven fabric forming equipment described in the present invention comprises a stretching structure between the support frames; a resistance structure is provided on the top side of the stretching structure; the cloth is pushed and stretched by the stretching structure to improve the flatness of the cloth during transportation; the cloth is rolled and flattened by the resistance structure, and the cloth in a stagnant state is conveniently fixed, that is: first, when the produced cloth is transported to the support frame, the cloth is sequentially wrapped around the guide roller, the stretching roller and another guide roller, so that the cloth presents a triangular bend during transportation, thereby increasing the traction force on the cloth during transportation and improving the flatness of the cloth. At the same time, for different types of non-woven fabrics, the user can also rotate the adjustment rods on both sides of the support frame, through the transmission action of the worm sleeve and the worm wheel, drive the first screws on both sides to rotate simultaneously, and then drive the threaded slider to slide on the side of the support frame, so that the bending height of the cloth changes, providing a stronger traction effect and ensuring the flatness of the cloth. A first screw rod is connected between the sliding shaft block and the threaded slider. A spring is used to avoid damaging the non-woven fabric while ensuring a good traction effect. A resistance roller is provided on the top side of the stretching roller. The user can change the distance between the stretching roller and the resistance roller by adjusting the height of the stretching roller. When the non-woven fabric passes between the two, it can be evenly rolled, thereby improving the overall flatness of the non-woven fabric and removing the fine wrinkles that have appeared on the non-woven fabric before. In addition, the rolling pressure can be adjusted in time according to the type of non-woven fabric to ensure the quality of the fabric. On the other hand, if the transportation of the non-woven fabric enters a stagnant state, at this time, in order to prevent the non-woven fabric in the front part of the device from losing traction and relaxing, the user can rotate the traction rod on the side of the support frame when stopping the transportation, so that the traction rod pushes the sliding tooth block through the push-pull block to engage with the tooth groove on the inner side of the resistance roller, thereby preventing the resistance roller from rotating freely. At this time, the clamping action between the stretching roller and the resistance roller can ensure that the non-woven fabric no longer slides, thereby ensuring that the front part of the non-woven fabric remains taut, which is convenient for subsequent continued transportation.

[0013] (2) The traction and stretching mechanism for non-woven fabric forming equipment described in the present invention comprises a conversion structure installed on one side of the support frame; a winding structure is provided between the conversion structure and the support frame; the driving position is quickly converted by the conversion structure, the non-woven fabric is wound up by the winding structure, and the non-woven fabric is quickly connected and fixed to the reel structure, that is, the motor installed on the side of the support frame is used to drive the winding of the non-woven fabric, and in order to facilitate the rapid replacement of the winding device, the end of the driving shaft is rotatably connected to a conversion plate, and a second rotating shaft is provided on both sides of the conversion plate for the non-woven fabric to be wound up. In order to switch between the two second shafts, a circular groove is provided on the inner side of the support frame. Under the push of the third spring, the pulley at the end of the second shaft will roll on the side wall of the circular groove. When the conversion plate rotates to a vertical state, the second shaft located on the top mounting block will move to a position closer to the driving shaft. At this time, the first gear is meshed with the second gear on the second shaft. When replacement is required, the conversion plate is continued to be rotated 180° so that the other second gear is meshed with the first gear, which is convenient for rapid replacement of the winding device and improves work efficiency. When the non-woven fabric is wound up, the electric The second rotating shaft arranged on the second gear meshing with the first gear can drive the corresponding winding rod to rotate and the non-woven fabric to be wound up. When the winding rod needs to be replaced, the transportation of the motor and the non-woven fabric is stopped, and then the replacement winding rod is installed, and one end of the winding rod passes through the limiting plate and is inserted into the extension groove. At this time, the end of the winding rod will push the support rod, and then the other end of the winding rod is engaged with the end of the second rotating shaft on the bottom side to ensure that the second rotating shaft can drive the winding rod to rotate normally, and the winding rod is released. Under the push of the fourth spring, the winding rod can be prevented from sliding into the extension groove again. , and then rotate the conversion plate 180°. At this time, the winding rod that has completed winding is rotated to the bottom side, and the non-woven fabric conflicts with the side of the winding rod that has rotated to the top side. The non-woven fabric is embedded in the end groove on the side of the winding rod through the clamping rod, and the clamping rod is prevented from falling out through the control blocks on both sides. At this time, the non-woven fabric part between the two winding rods can be cut. When removing the cloth roll that has been wound up, the operator only needs to slide the cloth roll toward the extension groove to release the engagement state between the winding rod and the second rotating shaft. At this point, the replacement of the winding rod is completed, which improves the replacement efficiency and ensures the tension of the non-woven fabric during the replacement process.

[0014] (3) In the traction and stretching mechanism for non-woven fabric forming equipment described in the present invention, a positioning structure is provided on the side of the conversion structure; the positioning structure ensures the overall stability of the device during the winding process of the non-woven fabric, that is, in order to prevent the conversion plate from rotating during the winding process, a positioning hole is provided at each end of the conversion plate, the positioning hole on the top side can cooperate with a fixing screw to prevent the conversion plate from continuing to rotate around the drive shaft, and the positioning hole on the bottom side can cooperate with a positioning rod to ensure that the rotation angle of the conversion plate is exactly 180°, which facilitates operation while ensuring the normal operation of the device.

[0032] When the present invention is in use, first, when the produced cloth is conveyed to the support frame 1, the cloth is sequentially passed around the guide roller 22, the stretching roller 23 and the other guide roller 22, so that the cloth presents a triangular bend during the conveying process, thereby increasing the traction force on the cloth body during the conveying process and improving the flatness of the cloth body. At the same time, for different types of non-woven fabrics, the user can also rotate the adjustment rods 21 on both sides of the support frame 1, through the transmission effect of the worm sleeve 29a and the worm wheel 29, to drive the first screws 28 on both sides to rotate simultaneously, and then drive the threaded slider 27 to slide on the side of the support frame 1, so that the bending height of the cloth body changes, providing a stronger traction effect, and ensuring the flatness of the cloth.

In addition, the rolling pressure can be adjusted in time according to the type of non-woven fabric to ensure the quality of the fabric. On the other hand, if the conveying of the non-woven fabric enters a stagnant state, at this time, in order to prevent the non-woven fabric in the front part of the device from losing the traction effect and relaxing, the user can rotate the traction rod 32 located on the side of the support frame 1 when the conveying is stopped, so that the traction rod The sliding tooth block 34 is pushed by the push-pull block 33 to engage with the tooth groove 36 on the inner side of the resistance roller 31, preventing the resistance roller 31 from rotating freely. At this time, the clamping action between the stretching roller 23 and the resistance roller 31 can ensure that the non-woven fabric no longer slides, thereby ensuring that the previous part of the non-woven fabric remains in a taut state, which is convenient for subsequent continued transportation. The motor 41 installed on the side of the support frame 1 is used to drive the winding of the non-woven fabric. In order to facilitate the rapid replacement of the winding device, the end of the drive shaft 42 is rotatably connected to a conversion plate 43. A second rotating shaft 47 is provided on both sides of the conversion plate 43 for winding the non-woven fabric. In order to switch between the two second rotating shafts 47, a circular groove 48 is opened on the inner side of the support frame 1. Under the push of the , the pulley 49 at the end of the second rotating shaft 47 will roll on the side wall of the circular groove 48. When the conversion plate 43 rotates to a vertical state, the second rotating shaft 47 located on the top side mounting block 45 will move to a position closer to the driving shaft 42. At this time, the first gear 44 is meshed with the second gear 49a on the second rotating shaft 47. When replacement is required, the conversion plate 43 is continued to be rotated 180° so that another second gear 49a is meshed with the first gear 44, which is convenient for rapid replacement of the winding device and improves work efficiency. When the non-woven fabric is wound up, the second rotating shaft 47 arranged on the second gear 49a meshed with the first gear 44 can drive the corresponding winding rod 51 to rotate and the non-woven fabric to be wound up through the drive of the motor 41.When it is necessary to replace the winding rod 51, the transportation of the motor 41 and the non-woven fabric is stopped, and then the replacement winding rod 51 is installed, and one end of the winding rod 51 is passed through the limit plate 52 and inserted into the extension groove 53. At this time, the end of the winding rod 51 will push the support rod 54, and then the other end of the winding rod 51 is engaged with the end of the second rotating shaft 47 on the bottom side to ensure that the second rotating shaft 47 can normally drive the winding rod 51 to rotate, and the winding rod 51 is released. Under the push of the fourth spring 55, the winding rod 51 can be prevented from sliding into the extension groove 53 again, and then the conversion plate 43 is rotated 180°. At this time, the winding rod 51 that has completed winding is rotated to the bottom side, and the non-woven fabric conflicts with the side of the winding rod 51 rotated to the top side. The non-woven fabric is embedded in the end groove 57 on the side of the winding rod 51 through the clamping rod 56, and through the control on both sides The block 58 prevents the locking rod 56 from coming out. At this time, the non-woven fabric portion between the two reeling rods 51 can be cut. When removing the reeled fabric roll, the operator only needs to slide the fabric roll toward the extension slot 53 to release the engagement between the reeling rod 51 and the second rotating shaft 47. At this point, the replacement of the reeling rod 51 is completed, which improves the replacement efficiency and ensures that the non-woven fabric is taut during the replacement process. In order to prevent the conversion plate 43 from rotating during the reeling process, a positioning hole 62 is respectively provided at both ends of the conversion plate 43. The positioning hole 62 on the top side can cooperate with the fixing screw 61 to prevent the conversion plate 43 from continuing to rotate around the driving shaft 42, and the positioning hole 62 on the bottom side can cooperate with the positioning rod 63 to ensure that the rotation angle of the conversion plate 43 is exactly 180°, which is convenient for operation and ensures the normal operation of the device.
