A flattening device for producing spunlace nonwoven fabric

Abstract

This utility model discloses a leveling device for spunlace nonwoven fabric production, including a worktable. A pair of bases are fixedly connected to the top right side of the worktable, and a motor is fixedly connected to the outer wall of each base. In actual use, when the spunlace nonwoven fabric shifts, it causes the outer shell to slide left and right. The outer shell is limited on the sliding rod by a connecting block. When the connecting block moves, it squeezes or pulls a spring, and the elasticity of the spring restores the outer shell to its original position, thereby correcting the shift of the spunlace nonwoven fabric. A pressure roller is installed on the top plate. Under the elastic action of a spring, the pressure roller presses the spunlace nonwoven fabric, ensuring that it is wound more tightly on the winding roller. This device solves the problems of spunlace nonwoven fabric shifting and loose winding that are common in existing winding equipment. Through the coordinated operation of various components, this device effectively ensures the neatness and tightness of the spunlace nonwoven fabric winding, improving product quality and production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of spunlace nonwoven fabric production technology, specifically a leveling device for spunlace nonwoven fabric production. Background Technology

[0002] The leveling unit in spunlace nonwoven fabric production is a key piece of equipment for ensuring product quality. The unwinding mechanism smoothly feeds the roll of nonwoven fabric into the leveling unit. This unit consists of smooth rollers that, through mechanical rolling or hot pressing, utilize adjustable pressure and precise temperature control to eliminate wrinkles on the nonwoven fabric surface, improving flatness and stiffness. The traction mechanism ensures the nonwoven fabric moves forward at a uniform speed, and finally, the winding mechanism neatly winds up the finished product. The entire unit operates efficiently under an automated control system, producing spunlace nonwoven fabrics with a smooth surface that meet the needs of various industries.

[0003] A search revealed that Chinese patent CN222313564U discloses a leveling device for spunlace nonwoven fabric production. The patent describes a technical solution that uses a first leveling roller and a second leveling roller to perform a double leveling operation on the wrinkled spunlace nonwoven fabric, thereby improving the treatment effect on the wrinkles of the spunlace nonwoven fabric and ensuring the winding quality and factory quality of the spunlace nonwoven fabric.

[0004] Although the solution achieves a double leveling effect, the device cannot correct or compact the spunlace nonwoven fabric during winding. When the spunlace nonwoven fabric deviates during winding, it directly leads to winding chaos and loose winding. In order to solve this technical problem, this utility model proposes a leveling device for spunlace nonwoven fabric production. Utility Model Content

[0009] Preferably, each of the bases is fixedly connected to a pair of springs, and a top plate is fixedly connected to the top of each spring. A pressure roller is rotatably connected to the lower center of the top plate. The pressure roller is located above the winding roller, and the outer shell is located in front of and above the winding roller.

[0010] Preferably, a pair of brackets are fixedly connected to the top of the workbench, and mounting blocks are fixedly connected to the outer walls of both the workbench and the brackets. A second motor is fixedly connected to the outer wall of one side of the mounting block, and a threaded rod is fixedly connected to the output end of the second motor.

[0011] Preferably, an adjusting roller is provided between the two sides of the bracket, and a connecting block two is rotatably connected to both ends of the adjusting roller.

[0013] Preferably, a pair of bases are fixedly connected to the top left side of the workbench, and a unwinding roller is provided between the two bases. A guide roller is fixedly connected to the top of the workbench, and the guide roller is located between the fixed frame and the base.

[0014] (III) Beneficial Effects

[0015] This utility model provides a leveling device for spunlace nonwoven fabric production. It has the following beneficial effects:

[0016] (1) After the motor starts, it drives the rotating shaft to rotate, which in turn drives the winding roller to rotate and perform the winding operation of the spunlace nonwoven fabric. When the spunlace nonwoven fabric deviates, it will drive the outer shell to slide left and right. The outer shell is limited on the slide rod by the connecting block one. When the connecting block one moves, it squeezes or pulls the spring one. The elasticity of the spring one makes the outer shell return to its original position, thereby correcting the deviation of the spunlace nonwoven fabric. The pressure roller is installed on the top plate. Under the elastic action of the spring two, the pressure roller presses the spunlace nonwoven fabric to ensure that it is wound more tightly on the winding roller. This device solves the problem of spunlace nonwoven fabric deviation and loose winding in existing winding equipment. In traditional equipment, nonwoven fabric deviation will cause winding chaos and loose winding will affect product quality. This device effectively ensures the neatness and tightness of spunlace nonwoven fabric winding through the coordinated cooperation of various components, thereby improving product quality and production efficiency.

[0017] (2) When it is necessary to adjust the tension of the spunlace nonwoven fabric, start motor two. Motor two drives the threaded rod to rotate. Since connecting block two is threadedly connected to the threaded rod, connecting block two will move up and down along the threaded rod during the rotation of the threaded rod. One end of connecting block two is connected to the adjusting roller, which in turn drives the adjusting roller to move up and down. The other side of the adjusting roller is limited on the positioning rod by connecting block two. The positioning rod ensures that the adjusting roller remains stable during the up and down movement and will not deviate or shake. This device solves the problem that existing equipment is difficult to adjust the tension of spunlace nonwoven fabric flexibly and accurately. Traditional devices often cannot adapt to the changes in the tension of nonwoven fabric in the production process in a timely manner, which affects the product quality. Through their coordinated cooperation, the tension of spunlace nonwoven fabric can be adjusted quickly and effectively according to the actual production situation, ensuring the smooth progress of the production process and improving product quality and production efficiency.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A leveling device for spunlace nonwoven fabric production includes a workbench 1. A pair of bases 2 are fixedly connected to the top right side of the workbench 1. A motor 3 is fixedly connected to the outer wall of the bases 2. A rotating shaft 4 is fixedly connected to the output end of the motor 3. A winding roller 5 is fixedly connected to the outer wall of the rotating shaft 4. A sliding rod 7 is fixedly connected to one side of the outer wall of each base 2. A housing 6 is provided at the top between the two bases 2. Connecting blocks 9 are fixedly connected to both sides of the housing 6. The connecting blocks 9 are slidably connected to the outer wall of the sliding rod 7. At the same time, a spring 8 is fixedly connected to the base 2 and the connecting blocks 9. The spring 8 is sleeved on the outer wall of the sliding rod 7. A pair of springs 11 are fixedly connected to the top of each base 2. A top plate 10 is fixedly connected to the top of the springs 11. A pressure roller 12 is rotatably connected to the lower middle of the top plate 10. The pressure roller 12 is located above the winding roller 5. The housing 6 is located in front of the upper part of the winding roller 5.

[0026] When the spunlace nonwoven fabric passes through the outer shell 6, the correction mechanism begins to function. If the spunlace nonwoven fabric deviates, it causes the outer shell 6 to slide left and right. The outer shell 6 is connected to the slide rod 7 via a connecting block 9, which is confined to slide on the slide rod 7. When the connecting block 9 moves outward or inward due to the sliding of the outer shell 6, it squeezes or pulls the connected spring 8. The spring 8, with its own resilience, applies a counterforce to the outer shell 6, pushing it back to its original position, thus achieving precise correction of the spunlace nonwoven fabric. During the winding stage, the pressure roller 12 on the top plate 10 tightly adheres to the spunlace nonwoven fabric. Under the elastic action of the second spring 11, the pressure roller 12 continuously applies pressure to the spunlace nonwoven fabric, making it more tightly wound on the winding roller 5, effectively preventing loosening or wrinkling during winding. The motor 3 is started, driving the rotating shaft 4, which in turn drives the winding roller 5 to perform the winding operation. The winding action is achieved through the correction structure of the outer shell 6, the cooperation between the pressure roller 12 and the spring 11, and the winding action driven by the motor 3.

[0027] Example 2: The difference between this example and Example 1 is that a pair of brackets 15 are fixedly connected to the top of the workbench 1. Mounting blocks 16 are fixedly connected to the outer walls of both the workbench 1 and the brackets 15. A second motor 17 is fixedly connected to the outer wall of one mounting block 16. A threaded rod 26 is fixedly connected to the output end of the second motor 17. An adjusting roller 19 is provided between the two brackets 15. A connecting block 18 is rotatably connected to both ends of the adjusting roller 19. One connecting block 18 is threadedly connected to the outer wall of the threaded rod 26. A positioning rod 20 is slidably connected inside the other connecting block 18, and the positioning rod 20 is fixedly connected between another pair of mounting blocks 16.

[0028] The unwind roller 14 is placed on the base 13, and then one end of the spunlace nonwoven fabric is guided to pass sequentially through the top of the adjusting roller 19, the bottom of the connecting plate 23, the bottom of the guide roller 25, and finally through the outer shell 6, extending to the winding roller 5, which is responsible for the winding operation. The electric push rod 22 on the top of the fixing frame 21 is activated. After the electric push rod 22 is activated, it generates thrust, pushing the connecting plate 23 downward. The leveling roller 24 installed on the connecting plate 23 then descends, thereby flattening the spunlace nonwoven fabric and ensuring its surface is flat. The motor 17 on the outside of the mounting block 16 is activated. After the motor 17 is running, it drives the threaded rod 26 to rotate. The rotation of the threaded rod 26 allows the connecting block 18 to move up and down along it. During the movement, the connecting block 18 drives the adjusting roller 19 to move up and down. The connecting block 18 on the other side slides at the upper limit of the positioning rod 20 to ensure the stability of the adjusting roller 19's movement. By adjusting the adjusting roller 19 up and down, the tension of the spunlace nonwoven fabric can be effectively adjusted.

[0029] Working principle: When the operator needs to level the spunlace nonwoven fabric, firstly, the unwind roller 14 is placed on the base 2 13. One end of the unwind roller passes through the top of the adjusting roller 19, the bottom of the connecting plate 23, and the bottom of the guide roller 25, and extends through the outer shell 6 to the winding roller 5, where it is wound up. At this time, the electric push rod 22 on the top of the fixing frame 21 is activated, pushing the leveling roller 24 on the connecting plate 23 downward and flattening the spunlace nonwoven fabric. During long-term processing, the tension of the spunlace nonwoven fabric will change. At this time, the motor 2 17 on the outside of the mounting block 16 is activated. Under the action of the motor 2 17, the threaded rod 26 is rotated, thereby driving the connecting block 2 18 to move up and down. The up and down movement of the connecting block 2 18 will drive the adjusting roller 19 to move up and down, and the connecting block 2 18 on the other side will limit it to the positioning rod 20. The up-and-down adjustment of the adjusting roller 19 can adjust the tension of the spunlace nonwoven fabric, ensuring safe and reliable conveying. When the spunlace nonwoven fabric passes through the outer shell 6, it will correct the deviation of the spunlace nonwoven fabric. When the spunlace nonwoven fabric deviates, it will drive the outer shell 6 to slide left and right. The outer shell 6 is limited on the slide rod 7 by the connecting block 19. When the connecting block 19 moves outward or inward, it will squeeze or pull the spring 18. The elasticity of the spring 18 will correct the outer shell 6, thereby correcting the spunlace nonwoven fabric. During the winding process, the pressure roller 12 on the top plate 10 will press the spunlace nonwoven fabric tightly. With the elasticity of the second spring 11, the spunlace nonwoven fabric is more compact on the winding roller 5. The starting motor 13 drives the winding roller 5 on the rotating shaft 4 to perform the winding operation. Through their cooperation, the spunlace nonwoven fabric is neatly wound up, improving work efficiency.
