Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically a nonwoven fabric roll forming machine. Background Technology

[0002] Nonwoven fabric is a sheet-like material made by first making textile fibers into a fiber web, and then bonding, sewing or hot pressing them together. In the production process of nonwoven fabric, a roll-forming machine is needed to wind the nonwoven fabric onto a roll for subsequent transfer and storage by workers.

[0003] In the prior art, a nonwoven fabric winding machine with the publication number "CN221644084U" uses a structural design of a first guide wheel, a forward and reverse motor, a second guide wheel, a first conveyor wheel, a second conveyor wheel, a third conveyor wheel, a winding roller, a guide wheel, and a transmission mechanism to facilitate the adjustment of the winding tension, that is, to reasonably adjust the distance between the third conveyor wheel and the first and second conveyor wheels, thereby improving the winding effect.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Although the winding machine can adjust the winding tension, the first guide roller inside the feed inlet and the second guide roller inside the feed outlet are fixed structures. This means that the two sets of first and second guide rollers can only guide nonwoven fabrics of the same thickness, and cannot guide nonwoven fabrics of different thicknesses, thus limiting its applicability. Secondly, because the winding roller in the winding machine is located inside the casing, it is very inconvenient for workers to disassemble and remove the winding roller containing nonwoven fabric later. Furthermore, the cooling mechanism in the winding machine uses two sets of fans blowing air from above and below to cool the nonwoven fabric. In actual use, this cooling method easily creates opposing turbulence in the middle area, resulting in a decrease in the air pressure acting on the heat dissipation target, making it impossible for heat to be quickly dissipated. Therefore, this cooling method has poor cooling effect. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By driving the connecting plate down through the first electric push rod, the connecting plate can drive the two sets of limiting pressure rollers on the left and right sides to descend together through the connecting vertical rod and the second connecting frame. Conversely, the two sets of limiting pressure rollers can rise together, so that the staff can match and adjust the distance between the limiting pressure rollers and the support rollers according to the different thicknesses of non-woven fabric, making the application range of the pressing component wider.

[0017] 2. By driving the connecting support plate down through the third electric push rod, the connecting support plate and the limit bracket can be lowered into place together.

Conversely, the winding drum can be installed and used, so that the operator can easily disassemble and install the winding drum later.

[0018] 3. By blowing cold air into the air inlet pipe using an industrial air cooler, the cold air is distributed sequentially through the air inlet pipe and the connecting tee to the first and second air guide pipes. The cold air entering the first air guide pipe is sprayed downwards through multiple first air nozzles to cool the upper surface of the non-woven fabric, while the cold air entering the second air guide pipe is sprayed upwards through multiple second air nozzles to cool the lower surface of the non-woven fabric. Furthermore, since the first and second air guide pipes in this structure are used in a staggered manner, the opposing airflow can be avoided from easily forming turbulent flow in the middle area, thus resulting in a better cooling effect.

The first electric push rod 79 is installed on the upper front face of the support plate 78. The first electric push rod 79 is electrically connected to an external control cabinet via a wire.

[0033] A second connecting frame 714 is connected to the lower end of the connecting vertical rod 713. The second connecting frame 714 can support and limit the limiting pressure roller 715 to prevent the limiting pressure roller 715 from shaking or slipping during use. The limiting pressure roller 715 is installed on the inner side of the second connecting frame 714. The limiting pressure roller 715 is a rotatable structure. The front and rear width of the limiting pressure roller 715 is greater than the front and rear width of the nonwoven fabric 2. The rotatable limiting pressure roller 715 can limit and guide the nonwoven fabric 2 to prevent the nonwoven fabric 2 from shifting upwards and jumping during the winding and tightening process. A second electric push rod 712 is installed at the middle position of the lower end face of the connecting hanging plate 76. The second electric push rod 712 is electrically connected to the external control cabinet via wires.

The rotatable tension roller 74 can press down and tighten the nonwoven fabric 2 to prevent the nonwoven fabric 2 from becoming loose during the winding process of the winding drum 9.

[0034] A first limiting rod 711 is provided on the rear side of the upper end face of the connecting plate 76.

[0035] Example 2:

[0036] Based on Embodiment 1, in this embodiment, the industrial air cooler 66 blows cold air into the air inlet pipe 65. The cold air then passes through the air inlet pipe 65 and the connecting tee 67 and is distributed to the first air guide pipe 62 and the second air guide pipe 64. The cold air entering the first air guide pipe 62 is sprayed downward through multiple first air nozzles 61 to cool the upper surface of the nonwoven fabric 2. At the same time, the cold air entering the second air guide pipe 64 is sprayed upward through multiple second air nozzles 63 to cool the lower surface of the nonwoven fabric 2. Since the first air guide pipe 62 and the second air guide pipe 64 are used in a staggered manner, the opposing airflow can avoid the formation of turbulent flow in the middle area, thus resulting in a better cooling effect.

[0037] The cooling component 6 includes a first air nozzle 61, a first air duct 62, an air inlet pipe 65, an industrial air cooler 66, and a connecting tee 67. The first air duct 62 is fixedly connected to the left side inside the back support plate 12. The first air duct 62 can distribute the cold air guided from the connecting tee 67 to multiple first air nozzles 61. Multiple first air nozzles 61 are arranged on the lower side of the annular side of the first air duct 62. The air sprayed downward by the multiple first air nozzles 61 is larger than the front and rear width of the non-woven fabric 2. The distance between the first air nozzles 61 and the non-woven fabric 2 is five centimeters. The multiple first air nozzles 61 can spray cold air downward to cool the upper surface of the non-woven fabric 2 passing below.

[0038] A second air duct 64 is fixedly connected to the lower right of the first air duct 62. The second air duct 64 can distribute the cold air from the connecting tee 67 to multiple second air nozzles 63. Multiple second air nozzles 63 are provided on the upper side of the annular side of the second air duct 64. The air sprayed downward by the multiple second air nozzles 63 is larger than the front and back width of the nonwoven fabric 2. The distance between the second air nozzles 63 and the nonwoven fabric 2 is five centimeters. The multiple second air nozzles 63 can spray cold air upward to cool the lower end surface of the nonwoven fabric 2 passing below.

[0039] Both the first air duct 62 and the second air duct 64 are fixedly connected to a connecting tee 67 at their rear inlets. The connecting tee 67 is connected to the air inlet pipe 65, the first air duct 62, and the second air duct 64 by welding. The connecting tee 67 can distribute the cold air from the air inlet pipe 65 to the first air duct 62 and the second air duct 64. Since the detailed internal structure and working principle of the connecting tee 67 are relatively mature technologies in the prior art, they will not be described in detail here. (The text then abruptly shifts to a seemingly unrelated topic: "Back support plate 12...") An industrial air cooler 66 is placed in the room. The industrial air cooler 66 is electrically connected to an external control cabinet via wires. When the industrial air cooler 66 is working, it can blow cold air into the air inlet pipe 65. Since the internal detailed structure and working principle of the industrial air cooler 66 are relatively mature technologies in the existing technology, they will not be described in detail here. The air inlet pipe 65 is connected between the air outlet end of the industrial air cooler 66 and the inlet end of the connecting tee 67. The air inlet pipe 65 can guide the cold air blown out by the industrial air cooler 66 into the connecting tee 67.

[0040] Example 3:

[0041] Based on Embodiment 1, in this embodiment, the connecting support plate 86 is lowered by the third electric push rod 81, which in turn lowers the limiting support 84 into place. At this time, the operator only needs to pull the winding drum 9 to disassemble and remove it. Conversely, the winding drum 9 can be installed and used, so that the operator can easily disassemble and install the winding drum 9 in the future.

[0042] The limiting assembly 8 includes a third electric push rod 81, a limiting support 84, an extension head 85, a connecting support plate 86, and a limiting groove 87. The third electric push rod 81 is mounted on the right side of the upper surface of the positioning base plate 1. The third electric push rod 81 is electrically connected to an external control cabinet via a wire. During operation, the third electric push rod 81 can drive the connecting support plate 86 to rise and fall. The connecting support plate 86 is mounted on the upper end of the third electric push rod 81. The connecting support plate 86 is connected to the limiting support 84 and the follower rod 83 by welding. The connecting support plate 86 can support the limiting support 84. A limiting support 84 is provided on the left side of the upper end face of 86. When the limiting support 84 moves upward and contacts the extension head 85, its rear end face will fit against the front end face of the take-up drum 9. A limiting groove 87 is provided on the upper end face of the limiting support 84, and the limiting groove 87 is U-shaped. The limiting groove 87 matches the extension head 85. The limiting support 84 with the U-shaped limiting groove 87 on the upper end face can not only support and limit the extension head 85, but also block and limit the front end face of the take-up drum 9, so as to prevent the take-up drum 9 from moving forward and slipping during rotation.

[0043] An extension head 85 is provided on the front end face of the extension shaft 13. The extension head 85 is connected to the extension shaft 13 by welding. The extension head 85 facilitates the limiting support 84 to support and limit the extension shaft 13, thereby ensuring the rotational stability of the extension shaft 13. A follower rod 83 is provided on the right side of the lower end face of the connecting support plate 86. A limiting sleeve 82 is fixedly connected to the right side of the upper end face of the positioning base plate 1. The limiting sleeve 82 is connected to the positioning base plate 1 by welding. The limiting sleeve 82 and the follower rod 83 are matched. The matched limiting sleeve 82 and the follower rod 83 prevent the connecting support plate 86 from shaking or shifting during lifting and lowering.

[0044] Working principle: In the production process of nonwoven fabric 2, one end of nonwoven fabric 2 from the external unwinding equipment is first passed sequentially through the upper side of the annular side of the guide roller 5, below the first air nozzle 61, above the second air nozzle 63, between the support roller 73 and the limiting pressure roller 715, and below the annular side of the tension roller 74, and finally wrapped and bonded to the take-up drum 9 (refer to...). Figure 1Then, the first electric push rod 79 drives the connecting plate 76 to descend, and the connecting plate 76 drives the two sets of limiting pressure rollers 715 on the left and right sides to descend together through the connecting vertical rod 713 and the second connecting frame 714. Similarly, when the first electric push rod 79 drives the connecting plate 76 to rise, the two sets of limiting pressure rollers 715 can rise together, so that the staff can match and adjust the distance between the limiting pressure rollers 715 and the support rollers 73 according to the different thicknesses of nonwoven fabric 2. After the adjustment is completed, the second electric push rod 712 drives the first connecting frame 75 to descend, so that the first connecting frame 75 drives the tension roller 74 to descend and press down and tighten the nonwoven fabric 2. When the tension roller 74 descends to the required height, the second electric push rod 712 can be stopped to prevent the nonwoven fabric 2 from becoming loose during the subsequent winding process of the winding drum 9, thereby ensuring the winding tightness of the winding drum 9.

[0045] Then, starting the industrial air cooler 66 will cause it to blow cold air into the air inlet pipe 65. The air inlet pipe 65 will guide the cold air to the connecting tee 67. At this time, the connecting tee 67 will distribute the cold air to the first air guide pipe 62 and the second air guide pipe 64. The cold air entering the first air guide pipe 62 will be sprayed downward through multiple first air nozzles 61 to cool the upper surface of the nonwoven fabric 2. At the same time, the cold air entering the second air guide pipe 64 will be sprayed upward through multiple second air nozzles 63 to cool the lower surface of the nonwoven fabric 2, thus preventing the nonwoven fabric 2 from deforming and sticking due to residual heat accumulation after subsequent winding.

[0046] Then, the operator only needs to start the low-speed motor 11, which will drive the take-up drum 9 to rotate at low speed through the transmission shaft 10 and the extension shaft 13 to take up the non-woven fabric 2. During this process, the third electric push rod 81 will support the limit support 84 through the connecting support plate 86, so that the limit support 84 can support and limit the extension shaft 13 through the extension head 85 to ensure the rotational stability of the extension shaft 13. When the non-woven fabric 2 is finished being rolled up and the take-up drum 9 needs to be removed, the operator first turns off the low-speed motor 11 and drives the connecting support plate 86 to descend through the third electric push rod 81. The connecting support plate 86 will drive the limit support 84 to descend together until the height of the limit support 84 is lower than the height of the take-up drum 9. At this time, the operator only needs to pull the take-up drum 9 to remove it. Conversely, the take-up drum 9 can be installed and used, so that the operator can easily install and disassemble the take-up drum 9.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
