Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to an anti-turnover net auxiliary device. Background Art

[0002] In the production of non-woven fabrics, the edges of the fiber web are thinner and prone to web flipping. To solve this problem, a limiting mechanism is currently used to limit the arrangement of fibers at the edge of the fiber web. However, due to the influence of the suction during web laying, some fibers that slide down along the limiting mechanism at the edge of the fiber web will protrude from the gap between the limiting mechanism and the mesh curtain, and the protruding part will still flip irregularly under the influence of the ambient airflow. To ensure product quality, all irregular web flipping must be cut off during the trimming process, resulting in great waste.

[0003] To solve the above problems, patent announcement number CN 212247408 U discloses a variable width lower suction duct device for spunbond nonwoven fabric production, which blocks the suction area on both sides of the fiber web by controlling the windshield curtain, so that the lateral width of the lower suction duct can be adjusted according to the change of product width. However, there are the following shortcomings in solving the net turning problem in this way: First, the servo motor drives the wire rope operation. This form will fail after a period of use, especially in the process of loosening the wire rope and then tightening it, the wire rope will be entangled on the rotating shaft of the servo motor; second, when expanding the width, the wire rope is loosened and the windshield curtain is rolled up manually. This process is not only troublesome but also laborious. Utility Model Content

[0018] Example 1

[0019] exist Figure 1 and Figure 3In the schematic diagram of the utility model shown, an anti-turnover net auxiliary device includes a support frame, a limit block, an upper windshield, a lower windshield, a first outer buckle, a second outer buckle and an electric push rod. The open side ends of the mountain-shaped support frame 1 are each provided with a limit block 2, the support frame is provided with an upper and lower layer, and an upper and lower layer of slide grooves are provided on the inner side of the frame in the transverse direction of the support frame. A group of upper windshields 3-1 are placed in the upper layer of the slide groove of the support frame, and a group of lower windshields 3-2 are placed in the lower layer of the slide groove of the support frame. The upper windshield and the lower windshield can slide along the slide groove. A first outer buckle 4 is provided at the lower part of the upper windshield, and the first outer buckle can be a C-shaped outer buckle. A second outer buckle 5 is provided at the upper part of the lower windshield, and the second outer buckle can be an I-shaped outer buckle. The first outer buckle and the second outer buckle can be buckled with each other. The push rod element in the electric push rod 6 is connected to the lower part of the lower windshield, and the electric push rod base is fixed to the steel structure of the net laying machine by bolts, and the electric push rod is operated by a remote control.

[0020] exist Figure 2 In the schematic diagram of the utility model shown, during the use of the utility model, two sets of anti-turnover net auxiliary devices correspond to one wire swing device, the two sets of anti-turnover net auxiliary devices are respectively placed on both sides of the suction duct under the laying net, and the supporting frame of the anti-turnover net auxiliary devices is arranged at the air outlet of the suction duct under the laying net.

[0021] During operation, when the width of the product is reduced, the remote control is operated to give instructions, and the electric push rod pushes the lower wind shield along the slide toward the middle of the web. During the movement of the lower wind shield, the I-shaped outer buckle and the C-shaped outer buckle engage with each other, thereby driving the upper wind shield to move along the slide toward the middle of the web. The maximum distance pushed by the electric push rod is when the lower wind shield reaches the limit position of the slide; when the width of the product is expanded, the remote control is operated to give instructions, and the electric push rod pulls the lower wind shield along the slide toward the two sides of the web. During the movement of the lower wind shield, the I-shaped outer buckle and the C-shaped outer buckle engage with each other, thereby driving the upper wind shield to move along the slide toward the two sides of the web until the wind shield returns to the zero position, and the action of the electric push rod ends.
