[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a stretching device for producing spunlace nonwoven fabrics, comprising a stretching device body 1, both sides of the stretching device body 1 are fixedly connected to a driving motor 2, both sides of the inner wall of the stretching device body 1 are rotatably connected to a rotating rod 3, the rear end of the rotating rod 3 is fixedly connected to an adjusting block 4, the interior of the adjusting block 4 is slidably connected to a slide plate 5, the number of the slide plates 5 is two and both are slidably connected to the interior of the adjusting block 4, and the right end of the slide plate 5 is fixedly connected to a connecting block 6. The right end of the connecting block 6 is fixedly connected to a clamping rod 7, a spring groove 8 is provided inside the slide plate 5, a force storage spring 9 is fixedly connected to the rear end of the spring groove 8, a limiting block 10 is fixedly connected to the front end of the force storage spring 9, and a limiting groove 11 is provided on the surface of the adjusting block 4. The staff places the cloth through the stretching device body 1 and squeezes the limiting block 10 inward. The limiting block 10 squeezes the force storage spring 9 to compress and store force. At the same time, the limiting block 10 and the limiting groove 11 are released from the limit. The staff moves the clamping rod 7 to clamp the cloth, starts the driving motor 2 to drive the rotating rod 3 and the adjusting block 4 to rotate, and the adjusting block 4 drives the clamping rod 7 to wind and stretch the cloth.

[0024] Reference Figure 4 As shown, in the present embodiment: slide grooves 12 are provided on both sides of the spring groove 8, and sliders 13 are fixedly connected on both sides of the limit block 10, and the surface of the slider 13 is slidably connected to the inside of the slide groove 12. When the staff moves the limit block 10, the limit block 10 drives the slider 13 to slide in the slide groove 12, and the movement trajectory of the limit block 10 is fixed by the setting between the slide groove 12 and the slider 13, thereby avoiding jamming during movement and making the rebound not smooth.

[0025] Reference Figure 3As shown, in the present embodiment: the bottom end of the inner cavity of the adjusting block 4 is fixedly connected with a thrust spring 14, and the top end of the thrust spring 14 is fixedly connected to the bottom end of the sliding plate 5. The staff compresses and accumulates the thrust spring 14 when moving the sliding plate 5 downward. When the staff releases the limit between the limit block 10 and the limit groove 11, the sliding plate 5 is quickly pushed upward under the action of the rebound force of the thrust spring 14, so that the limit block 10 is quickly aligned with the limit groove 11 and pops out for limiting.

[0026] Reference Figure 5 As shown, in this embodiment: sliding grooves 15 are opened on both sides of the adjusting block 4, and sliding blocks 16 are fixedly connected on both sides of the sliding plate 5. The surface of the sliding block 16 is slidably connected to the inside of the sliding groove 15. When the staff moves the sliding plate 5, the sliding plate 5 drives the sliding block 16 to slide in the sliding groove 15. Through the setting between the sliding groove 15 and the sliding block 16, the moving trajectory of the sliding plate 5 is fixed, thereby avoiding the sliding plate 5 from shaking during the movement and causing unsmooth movement.

[0027] Reference Figure 1 and Figure 6 As shown, in the present embodiment: a base 17 is fixedly connected to the four sides of the bottom of the stretching device body 1, a support column 18 is slidably connected inside the base 17, a support block 19 is fixedly connected to the bottom of the support column 18, a shock-absorbing spring 20 is fixedly connected to the top of the inner cavity of the base 17, and the bottom end of the shock-absorbing spring 20 is fixedly connected to the top of the support column 18. A lot of noise and vibration will be generated during the operation of the driving motor 2. Through the setting of the shock-absorbing spring 20, the shock-absorbing spring 20 buffers the vibration of the stretching device body 1 to avoid excessive noise during operation due to force from the ground, while suppressing vibration to increase the service life of the equipment.

[0028] Reference Figure 6 As shown, in the present embodiment: movable grooves 21 are provided on both sides of the interior of the base 17, movable blocks 22 are fixedly connected on both sides of the support column 18, and the surface of the movable block 22 is slidably connected to the interior of the movable groove 21. Through the arrangement of the movable groove 21 and the movable block 22, when the staff moves the support column 18, the movable block 22 is driven to move inside the movable groove 21, so that the moving trajectory of the support column 18 is fixed, and at the same time, the support column 18 is prevented from falling off and being damaged.

[0029] Reference Figure 1 As shown, in this embodiment: the material of the clamping rod 7 is polyetherimide. By setting the clamping rod 7 to be made of polyetherimide, the fire safety hazard caused by static electricity during the working process of the clamping rod 7 is avoided, and the cost is low, which is convenient for subsequent maintenance by the staff.

[0030] When the staff releases the limit of the limit block 10 and the limit groove 11, the slide plate 5 is quickly pushed upward under the action of the rebound force of the thrust spring 14, so that the limit block 10 is quickly aligned with the limit groove 11 and pops up to carry out the work. The limit position, when the staff moves the slide plate 5, the slide plate 5 drives the sliding block 16 to slide inside the sliding groove 15. The setting between the sliding groove 15 and the sliding block 16 fixes the movement trajectory of the slide plate 5, thereby preventing the slide plate 5 from shaking and causing unsmooth movement during the movement. A large amount of noise and vibration will be generated during the operation of the driving motor 2. The setting of the shock-absorbing spring 20 buffers the vibration of the stretching device body 1, thereby preventing the force from being applied to the ground to cause excessive noise during operation, and at the same time suppressing vibration to increase the service life of the equipment. The setting of the moving groove 21 and the moving block 22 drives the moving block 22 to move inside the moving groove 21 when the staff moves the support column 18, thereby fixing the movement trajectory of the support column 18, and preventing the support column 18 from falling off and causing damage. The setting of the clamping rod 7 as a polyetherimide material avoids the fire safety hazard caused by static electricity during operation, and the cost is low, which is convenient for subsequent maintenance by the staff.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
