Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric production technology, and in particular relates to a stretching device for spunlace nonwoven fabric production. Background Technology

[0002] The stretching unit used in the production of spunlace nonwoven fabrics needs to stretch and shape the fabric. However, existing spunlace nonwoven fabric stretching machines are fixed in their settings. To improve the adjustability of the stretching process when dealing with different material thicknesses and stretching requirements, rollers of different diameters need to be replaced. A search revealed that patent application number 202421466491.4 discloses a stretching device for spunlace nonwoven fabric production. This device includes a stretching device body, an adjusting block fixedly connected to the rear end of a rotating rod, a sliding plate slidably connected inside the adjusting block, a connecting block fixedly connected to the right end of the sliding plate, a clamping rod fixedly connected to the right end of the connecting block, a spring groove inside the sliding plate, a storage spring fixedly connected to the rear end of the spring groove, and a limit block fixedly connected to the front end of the storage spring.

[0003] However, in actual use, the applicant found that when adjusting the distance between the two clamping bars, it is necessary for personnel to squeeze the limiting block inward and move the sliding plate to adjust the position so that the limiting block is engaged in the corresponding limiting groove in order to complete the adjustment of the distance between the clamping plates. The operation is not convenient and precise enough. In view of this, we propose a stretching device for spunlace nonwoven fabric production. Utility Model Content

Motors 2 are symmetrically fixedly mounted on both sides of the stretching device body 1. The output end of the motor 2 movably passes through the side wall of the stretching device body 1 and is fixedly connected to a rotating seat 3. The rotating seat 3 includes a frame 31. Slider blocks 32 are symmetrically slidably connected inside the frame 31. A double-ended screw 33 is rotatably connected inside the frame 31 via bearings, and the threads at both ends of the double-ended screw 33 have opposite directions. The two ends of the double-ended screw 33 are threaded through two sliders 32 respectively. The upper end of the double-ended screw 33 extends to the outside of the frame 31 and is fixedly connected to an adjusting handle 34. A hexagonal groove 341 is formed at the top of the adjusting handle 34. The sliders 32 inside the rotating seats 3 on both sides are connected by clamping rods 4. Two clamping rods 4 are provided and arranged parallel to each other. One end of each clamping rod 4 is fixedly connected to two sliders 32 in one side of the rotating seat 3, and the other end of each clamping rod 4 is fixedly connected to the other side of the rotating seat 3. The two sliders 32 in the rotating seat 3 are fixedly connected. By manually rotating the adjusting handles 34 on the upper part of the two rotating seats 3 clockwise, the double-headed screw 33 is driven to rotate. The double-headed screw 33 can drive the two sliders 32 in the rotating seat 3 to move closer or further away synchronously, thereby driving the two clamping rods 4 to move closer or further away synchronously. The distance between the two clamping rods 4 can be adjusted to stretch spunlace nonwoven fabrics of different thicknesses. The operation is convenient and precise. The operator places the fabric through the stretching device body 1 and passes one end of the fabric between the two clamping rods 4. By manually rotating the adjusting handles 34 on the two rotating seats 3 clockwise, the double-headed screw 33 is driven to rotate. The rotation of the double-headed screw 33 can drive the two sliders 32 to move closer synchronously. The movement of the sliders 32 can drive the two clamping rods 4 to move closer synchronously. The fabric is clamped by the two clamping rods 4. Then, the drive motor 2 drives the rotating seat 3 to rotate.

The lower ends of the rotating shafts 53 extend to the outside of the frame 51. A worm 52 is rotatably connected to the frame 51 behind the worm gears 54 via bearings. Both worm gears 54 are drively connected to the worm 52. One end of the worm 52 extends to the outside of the frame 51 and is fixedly fitted with a handle 521. Anti-slip teeth are evenly distributed on the outer wall of the handle 521. The adjusting mechanism... 5. It can realize the synchronous rotation of the upper adjustment handles 34 of the two rotating seats 3, making it easier to adjust the distance between the two clamping rods 4. When adjusting the distance between the two clamping rods 4, the two hexagonal protrusions 531 at the bottom of the adjustment mechanism 5 can be inserted into the hexagonal grooves 341 on the upper part of the two rotating seats 3 respectively, and the worm gear 52 can be rotated by manually turning the handle 521 clockwise. The rotation of the worm gear 52 can drive the two worm wheels 54 to rotate synchronously together with the rotating shaft 53. The rotation of the rotating shaft 53 can drive the hexagonal protrusions 531 to rotate. The rotation of the two hexagonal protrusions 531 can drive the two adjustment handles 34 to rotate synchronously, thereby quickly adjusting the distance between the two clamping rods 4.

[0023] Working principle: In use, the operator places the fabric through the stretching device body 1 and passes one end of the fabric between the two clamping rods 4. The two hexagonal protrusions 531 at the bottom of the adjusting mechanism 5 are inserted into the hexagonal grooves 341 on the top of the two rotating seats 3 respectively. By manually turning the handle 521 clockwise, the worm gear 52 is driven to rotate. The rotation of the worm gear 52 drives the two worm wheels 54 and the rotating shaft 53 to rotate synchronously. The rotation of the rotating shaft 53 drives the hexagonal protrusions 531 to rotate. The rotation of the two hexagonal protrusions 531 drives the two adjusting handles 34 to rotate synchronously. The rotation of the adjusting handles 34 drives the double-headed screw 33 to rotate. The rotation of the double-headed screw 33 drives the two sliders 32 to move closer synchronously. The movement of the sliders 32 drives the two clamping rods 4 to move closer synchronously. The fabric is clamped by the two clamping rods 4. Then, the drive motor 2 drives the rotating seat 3 to rotate. The rotation of the rotating seat 3 drives the clamping rods 4 to wrap and stretch the fabric.
