Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a feeding, leveling and anti-wrinkle device for nonwoven fabric production. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it resembles the appearance and some properties of fabric. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. The leveling process is a crucial step in non-woven fabric processing, and its quality directly affects the quality of the non-woven fabric.

[0003] A search revealed a feeding, leveling, and anti-wrinkle device (Chinese Patent No. CN222204249U) comprising a base, an unwinding device mounted on the top of the base, and a leveling unit on one side of the unwinding device. The leveling unit includes a fixed frame, a support, a support plate, a heating box, a hose, a movable roller, a connecting pipe, a heating roller, a spring, an air pump, and a movable rod. The fixed frame is fixedly connected to the top of the base, and the movable rod is movably connected to the top of the fixed frame. A spring is sleeved on the outer wall of the movable rod, and the top of the spring is fixedly connected to the top of the fixed frame.

[0004] However, the aforementioned feeding, leveling, and anti-wrinkle device still has shortcomings. Before leveling the nonwoven fabric, it is inconvenient to remove dust and lint from the nonwoven fabric. Under the pressure of the rollers, dust and lint are easily pressed into the surface of the nonwoven fabric, thereby reducing the quality of the nonwoven fabric. Furthermore, it can only level the nonwoven fabric from side to side, and it is inconvenient to level the nonwoven fabric from front to back, which reduces the leveling and anti-wrinkle effect. Therefore, we propose a feeding, leveling, and anti-wrinkle device for nonwoven fabric production to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned shortcomings and to propose a feeding, leveling and anti-wrinkle device for non-woven fabric production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding, leveling, and anti-wrinkle device for nonwoven fabric production includes a feeding frame for feeding nonwoven fabric. Two guide rollers are rotatably connected to the inner walls of the front and rear sides of the feeding frame. A support plate is fixedly connected to the inner walls of the front and rear sides of the feeding frame, and a tensioning mechanism is provided on the support plate. A cover is fixedly connected to the front side of the feeding frame. A dust-collecting and heating mechanism is provided between the cover and the feeding frame. The dust-collecting and heating mechanism includes two dust-collecting pipes and two hot air pipes fixedly installed on the inner walls of the front and rear sides of the feeding frame. A full leveling mechanism is provided between the cover and the feeding frame. The full leveling mechanism includes a leveling roller, a pressure roller, and a rotating roller rotatably installed on the inner walls of the front and rear sides of the feeding frame. Two open-width patterns with opposite rotation directions are provided on the outer side of the rotating roller.

[0008] As a preferred embodiment of this utility model, the tensioning mechanism includes two tensioning springs fixedly connected to the top of the support plate. The top ends of the two tensioning springs are fixedly connected to a limiting plate, and the bottom of the limiting plate is fixedly connected to a lifting rod. The lower ends of the two lifting rods are fixedly connected to the same mounting frame, and the front and rear inner walls of the mounting frame are rotatably connected to the same tensioning roller.

[0009] In a preferred embodiment of this invention, both lifting rods slide through the support plate, and two tension springs are respectively sleeved on the outer side of the corresponding lifting rods.

[0010] As a preferred embodiment of this utility model, the dust collection and heating mechanism includes a partition fixedly connected to the inside of the cover, two dust collection pipes and two hot air blowing pipes connected to the cover, a dust collection box slidably sleeved inside the cover, a suction pump fixedly connected to one side of the partition, and two heating rods fixedly connected between the cover and the feeding rack.

[0011] As a preferred embodiment of this invention, a filter screen is fixedly connected to the partition, and the suction end of the suction pump is connected to the filter screen.

[0012] As a preferred embodiment of this utility model, the front side of the cover is provided with an outlet, and the dust collection box is slidably sleeved inside the outlet.

[0013] In a preferred embodiment of this invention, the suction pipe, partition, suction pump, heating rod, and hot air pipe are arranged sequentially from left to right.

[0014] As a preferred embodiment of this utility model, the full leveling mechanism further includes a servo motor fixedly connected to one side of the cover. A rotating shaft is fixedly connected to the output shaft of the servo motor. Two active bevel gears are fixedly sleeved on the outer side of the rotating shaft. Driven bevel gears are fixedly connected to the front ends of both the rotating roller and the leveling roller. The two active bevel gears mesh with the corresponding driven bevel gears respectively. The pressure roller cooperates with the leveling roller.

[0015] In this utility model, a feeding, leveling and anti-wrinkle device for non-woven fabric production can tension the non-woven fabric under the action of tension spring and tension roller to prevent the non-woven fabric from being too loose and wrinkled. Through a suction pump, dust and lint and other impurities on the upper and lower surfaces of the non-woven fabric can be sucked into the dust suction pipe and cover. After being filtered and intercepted by the filter screen, the dust and lint are intercepted in the dust collection box for collection and treatment.

[0016] In this utility model, a feeding, leveling, and anti-wrinkle device for nonwoven fabric production is described. Filtered air enters the cover on the right side of the partition, is heated by a heating rod, and then hot air is blown from the hot air pipe to heat the nonwoven fabric from top to bottom. The heated nonwoven fabric enters between the pressure roller and the leveling roller. A servo motor drives the rotation of the rotating shaft. Through the meshing transmission of two sets of bevel gears, the rotating shaft drives the rotation of the leveling roller and the rotating roller. Under the action of the pressure roller and the leveling roller, the nonwoven fabric can be hot-pressed and leveled to avoid left and right wrinkles. Through two open-width patterns with opposite rotation directions, the nonwoven fabric can be pulled back and forth to avoid front and back wrinkles, thereby ensuring the flatness of the nonwoven fabric during feeding and making the anti-wrinkle effect better.

[0017] This utility model has a reasonable structural design. It can first clean away dust, lint and other impurities on the upper and lower surfaces of the non-woven fabric, and prevent dust and lint from being pressed into the non-woven fabric under hot pressing, which would reduce the quality of the non-woven fabric. Through hot pressing and two open-width patterns with opposite directions, the non-woven fabric can be flattened left and right and stretched back and forth, avoiding wrinkles and ensuring the flatness of the non-woven fabric during feeding, resulting in a better anti-wrinkle effect.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A feeding, leveling, and anti-wrinkle device for nonwoven fabric production includes a feeding frame 1 for feeding nonwoven fabric. Two guide rollers 7 are rotatably connected to the inner walls of the front and rear sides of the feeding frame 1. A support plate 3 is fixedly connected to the inner walls of the front and rear sides of the feeding frame 1. A tensioning mechanism 4 is provided on the support plate 3. A cover 2 is fixedly connected to the front side of the feeding frame 1. A dust-collecting and heating mechanism 6 is provided between the cover 2 and the feeding frame 1. The dust-collecting and heating mechanism 6 includes two dust-collecting pipes 64 and two hot air pipes 62 fixedly installed on the inner walls of the front and rear sides of the feeding frame 1. A full leveling mechanism 5 is provided between the cover 2 and the feeding frame 1. The full leveling mechanism 5 includes a leveling roller 57, a pressure roller 58, and a rotating roller 55 rotatably installed on the inner walls of the front and rear sides of the feeding frame 1. Two open-width patterns 56 with opposite rotation directions are provided on the outer side of the rotating roller 55.

[0025] Furthermore, refer to Figure 1 and Figure 2 The tensioning mechanism 4 includes two tensioning springs 42 fixedly connected to the top of the support plate 3. The top of each tensioning spring 42 is fixedly connected to a limit plate 41. The bottom of the limit plate 41 is fixedly connected to a lifting rod 43. The bottom of the two lifting rods 43 is fixedly connected to the same mounting frame 44. The same tensioning roller 45 is rotatably connected to the inner walls of the front and rear sides of the mounting frame 44.

[0026] By adopting the above solution, the nonwoven fabric can be tensioned by the action of the tension spring 42 and the tension roller 45, so as to avoid the nonwoven fabric from being too loose and wrinkling.

[0027] Furthermore, both lifting rods 43 slide through the support plate 3, and two tension springs 42 are respectively sleeved on the outer side of the corresponding lifting rods 43, which helps to guide the mounting frame 44 and the tension springs 42, making their movement more stable and smooth.

[0028] Furthermore, refer to Figures 1-4 The dust collection and heating mechanism 6 includes a partition 67 fixedly connected inside the cover 2, two dust collection pipes 64 and two hot air blowing pipes 62 connected to the cover 2, a dust collection box 66 slidably sleeved inside the cover 2, a suction pump 61 fixedly connected to one side of the partition 67, two heating rods 65 fixedly connected between the cover 2 and the feeding rack 1, a filter screen 63 fixedly connected to the partition 67, and the suction end of the suction pump 61 connected to the filter screen 63. The dust collection pipes 64, partition 67, suction pump 61, heating rods 65 and hot air blowing pipes 62 are arranged sequentially from left to right.

[0029] Using the above scheme: the suction pump 61 can suck the dust and lint and other impurities on the upper and lower surfaces of the non-woven fabric into the suction pipe 64 and the cover 2. After being filtered and intercepted by the filter screen 63, the dust and lint are intercepted into the dust collection box 66 for collection and treatment. The filtered air enters the cover 2 on the right side of the partition 67, is heated by the heating rod 65, and then blows hot air from the hot air blowing pipe 62 to heat the upper and lower surfaces of the non-woven fabric.

[0030] Furthermore, an outlet is provided on the front side of the cover 2, and the dust collection box 66 is slidably fitted inside the outlet, making it convenient to pull the dust collection box 66 to clean the dust, lint and other impurities inside.

[0031] Furthermore, refer to Figures 1-3 The full leveling mechanism 5 also includes a servo motor 51 fixedly connected to one side of the cover 2. A rotating shaft 53 is fixedly connected to the output shaft of the servo motor 51. Two active bevel gears 52 are fixedly sleeved on the outer side of the rotating shaft 53. Driven bevel gears 54 are fixedly connected to the front ends of the rotating roller 55 and the leveling roller 57. The two active bevel gears 52 mesh with the corresponding driven bevel gears 54 respectively. The pressure roller 58 cooperates with the leveling roller 57.

[0032] Using the above scheme: The heated nonwoven fabric enters between the pressure roller 58 and the leveling roller 57. The servo motor 51 drives the rotation of the rotating shaft 53. Through the meshing transmission of two sets of bevel gears, the rotating shaft 53 drives the rotation of the leveling roller 57 and the rotating roller 55. Under the action of the pressure roller 58 and the leveling roller 57, the nonwoven fabric can be hot-pressed and leveled to avoid left and right wrinkles. Through two open-width patterns 56 with opposite rotation directions, the nonwoven fabric can be pulled back and forth to avoid front and back wrinkles, thereby ensuring the flatness of the nonwoven fabric during feeding and making the anti-wrinkle effect better.

[0033] In this invention, during use, the nonwoven fabric is tensioned by the tension spring 42 and tension roller 45 to prevent it from becoming too loose and wrinkled. The suction pump 61 draws dust and lint from the upper and lower surfaces of the nonwoven fabric into the suction pipe 64 and the cover 2. After being filtered by the filter screen 63, the dust and lint are collected in the dust collection box 66. The filtered air enters the cover 2 on the right side of the partition 67, is heated by the heating rod 65, and then blown hot air from the hot air pipe 62 to heat the nonwoven fabric from both sides. The heated nonwoven fabric enters between the pressure roller 58 and the leveling roller 57. The servo motor 51 drives the rotating shaft 53 to rotate. Through the meshing transmission of two sets of bevel gears, the rotating shaft 53 drives the leveling roller 57 and the rotating roller 55 to rotate. Under the action of the pressure roller 58 and the leveling roller 57, the nonwoven fabric can be hot-pressed and leveled to avoid left and right wrinkles. Through two open-width patterns 56 with opposite rotation directions, the nonwoven fabric can be pulled back and forth to avoid front and back wrinkles, thus ensuring the flatness of the nonwoven fabric during feeding and making the anti-wrinkle effect better.
