Description

Technical Field

[0001] The invention relates to the field of non-woven fabric production equipment, in particular to a non-woven fabric wrinkling machine based on the combination of pulse airflow vibration and thermal effect. Background Art

[0002] Non-woven fabrics often need to be wrinkled during the production process. The main purpose of wrinkling is to wrinkle the surface to improve the adsorption capacity of the product. The traditional wrinkling method is to use a wrinkling machine as shown in patent announcement document CN105642747B. The wrinkling method of this wrinkling machine heats the material to be wrinkled and then rolls it. Since it is heated first and then rolled, the fibers on the non-woven fabric in the heated state will partially melt. When the chemical fiber in the molten state is rolled, the chemical fiber will stick to the roller. Secondly, rolling after melting will cause the thickness of each part of the non-woven fabric to be different, resulting in uneven thickness. Summary of the invention

[0003] In view of the above problems, the present invention proposes a non-woven fabric wrinkling machine based on the combination of pulse airflow vibration and thermal effect.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A non-woven fabric wrinkling machine based on the combination of pulse airflow vibration and thermal effect, comprising a base frame, a reel, a conveying roller, a reeling roller, a rigid pressing plate, a jet head, a lifting cylinder and a flexible spring sheet pressing plate, wherein the reel, the conveying roller and the reeling roller are all rotatably mounted on the base frame, and the conveying roller is located between the reel and the reeling roller, one end of the rigid pressing plate is rotatably mounted on the base frame, one end of the lifting cylinder is rotatably matched with the rigid pressing plate, the jet head is arranged on the rigid pressing plate, and the nozzle of the jet head faces the roller surface of the conveying roller, one end of the flexible spring sheet pressing plate is rotatably mounted on the rigid pressing plate, a torsion spring is arranged between the rigid pressing plate and the flexible spring sheet pressing plate, the torsion spring is used to bounce the flexible spring sheet pressing plate toward and close to the roller surface of the conveying roller, and there is a gap between the rigid pressing plate and the roller surface of the conveying roller.

[0006] In the wrinkling machine of the present invention, the unwinding roller is used to release the non-woven fabric roll, and the winding roller is used to wind up the non-woven fabric roll, and the conveying roller plays the role of transferring the non-woven fabric. In the wrinkling machine of the present invention, the gap between the rigid pressing plate and the roller surface of the conveying roller is a channel for the non-woven fabric to pass through. The specific process is: when the non-woven fabric in a wet state is conveyed to the conveying roller and is attached to the roller surface of the conveying roller, the rigid pressing plate and the flexible spring plate form a wrinkling cavity. When the non-woven fabric runs into the wrinkling cavity, the pulse hot air flow ejected by the nozzle is sprayed onto the non-woven fabric. The pulse hot air flow wrinkles the surface of the non-woven fabric and dries it at the same time. At the same time, the flexible spring plate vibrates under the pulse airflow, and the vibrating flexible spring plate continuously beats the non-woven fabric. Under the dual action, the non-woven fabric is stacked in the wrinkling cavity, thereby forming wrinkles. Due to the irregular characteristics of the pulse airflow, the formed wrinkles are tight and irregular.

[0007] In the wrinkling machine of the present invention, the temperature of the hot air ejected from the nozzle is higher than the temperature of the wet nonwoven fabric, but the temperature of the hot air is lower than the melting point of the nonwoven fabric fibers, and the hot air will not heat the fibers on the nonwoven fabric to a melting state.

[0008] In summary, the wrinkling machine of the present invention wrinkles the non-woven fabric by means of a jet nozzle and a flexible spring plate pressing plate, without heating the non-woven fabric to a molten state.

[0009] The function of the lifting cylinder is to adjust the rotation of the rigid pressing plate to ensure that a wrinkling cavity can be formed between the rigid pressing plate, the flexible elastic pressing plate and the conveying roller.

[0010] Optionally, it also includes an air flow material starting nozzle, which is arranged on the base frame, and the air jet head and the air flow material starting nozzle are respectively located on both sides of the central axis of the conveying roller.

[0011] The function of the air flow nozzle is to blow the non-woven fabric (which has been wrinkled) attached to the conveying roller away from the conveying roller so that the non-woven fabric is no longer attached to the conveying roller.

[0012] Optionally, it also includes a material starting plate, a mounting base and a bracket, the material starting plate and the airflow material starting nozzle are both mounted on the mounting base, the bracket is arranged on the base frame, one end of the mounting base is rotatably engaged with the base frame, one end of the lifting cylinder is rotatably engaged with the mounting base, and the other end of the lifting cylinder is rotatably engaged with the bracket.

[0013] The nonwoven fabric (after wrinkling) slides off the conveying roller along the pick-up plate. The airflow pick-up nozzle and the pick-up plate are both mounted on a mounting base, one end of the mounting base is rotatably mounted on a bracket, and the mounting base can rotate around the connection between the two. The rotation of the mounting base is driven by a lifting cylinder.

[0014] Optionally, it also includes a first tensioning roller and a second tensioning roller, wherein the first tensioning roller and the second tensioning roller are both rotatably arranged on the base frame, the first tensioning roller is located between the unwinding roller and the conveying roller, and the second tensioning roller is located between the conveying roller and the winding roller.

[0015] Optionally, there are multiple nozzles, and all nozzles are arranged on the rigid pressing plate, and the nozzles are used to spray hot air.

[0016] Optionally, it also includes a mounting block, which is arranged on the rigid pressure plate, and one end of the flexible spring plate is rotatably mounted on the mounting block of the rigid pressure plate, and the two ends of the torsion spring respectively resist the mounting block on the rigid pressure plate and the flexible spring plate.

[0017] Optionally, a peristaltic air pump is also included, and the peristaltic air pump is connected to the jet head.

[0018] Specifically, a groove is opened at the bottom of the rigid pressing plate to facilitate the discharge of the air pipe, and a through hole is used to install the nozzle at the front of the pressing plate. The air pipe connects the nozzle and the peristaltic air pump. The nozzle sprays pulse airflow under the control of the multi-valve controller to vibrate the surface of the fabric and the flexible spring plate.

[0019] Optionally, it also includes an unwinding motor, which is arranged on the base frame, and the unwinding roller and the unwinding motor are matched together through a synchronous belt.

The conveying roller 6 plays the role of transferring the non-woven fabric. In the wrinkling machine of the present invention, the gap between the rigid pressing plate 501 and the roller surface of the conveying roller 6 is a channel for the non-woven fabric to pass through. The wrinkling process of the wrinkling machine of the present invention is as follows: when the non-woven fabric in a wet state is conveyed to the conveying roller 6 and is attached to the roller surface of the conveying roller 6, the rigid pressing plate 501 and the flexible spring plate pressing plate 505 form a wrinkling When the non-woven fabric runs into the wrinkling chamber, the pulse hot air flow ejected by the nozzle 502 is blown onto the non-woven fabric, and the pulse hot air flow wrinkles the surface of the non-woven fabric and dries it at the same time. After being dried, the non-woven fabric will remain in a wrinkled state, and at the same time, the flexible spring plate 505 will vibrate under the pulse air flow, and the vibrating flexible spring plate 505 will continuously beat the non-woven fabric.
