Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to a vertical web laying device for textile production. Background Art

[0002] The vertical web laying machine cross-folds the thin fiber web output by the carding machine through its unique vertical clamping curtain reciprocating swing, and evenly lays it into a multi-layer fiber web of a certain thickness and amplitude. This web laying method can ensure the uniformity and stability of the fiber web, and provide high-quality fiber web materials for subsequent processes. The vertical web laying machine has a high degree of automation, which can greatly reduce labor and improve production efficiency. Its feeding mechanism, web laying mechanism, pulling mechanism and winding mechanism work together to realize a fully automated production process from material input to finished product output. In addition, the vertical web laying machine can be quickly adjusted according to different materials and weaving requirements, and has strong adaptability. Whether it is fiber, yarn or silk, it can be woven into a mesh structure by the vertical web laying machine. At the same time, its stacking speed and amplitude can also be adjusted according to actual needs to meet the production needs of different products.

[0003] At present, when the vertical web laying machines for textile production on the market are in use, the web laying curtain drives the fiber web to swing back and forth, so that the bending parts of the fiber web will be repeatedly overlapped, causing wrinkles on the edges of the fiber web, and the overlapped fiber web is compacted by rollers.

Electrically connected, the transmission ratio of the second gear 26 and the third gear 35 is 1:10, the sleeve rod 32 on the left side of the support base 27 is longer than the sleeve rod 32 on the right side, and an anti-dropping sheet is installed on the front end of the sleeve rod 32. Support holes are provided inside the first support 29 and the second support 33. The bottom end of the synchronous cross frame 17 is fitted with the top of the support base 27, the guide plate 3 is connected to the right side of the support frame 21, and a square hole is provided inside the sleeve plate 4. The conveyor belt 13 is vertically aligned with the mesh curtain 20, and the bottom rear end of the iron 22 is inclined at 45°. The bottom end of the connecting base 25 is horizontally aligned with the top of the photoelectric sensor 31.

[0038] The working principle of embodiment 1 is as follows: when in use, the end of the external fiber web is first slid along the guide plate 3 and placed between the two laying curtains 20 until the end of the fiber web moves and is placed flat on the conveyor belt 13. A feeding rubber wheel is installed on the top of the support frame 21, and the fiber web is in contact with the surface of the feeding rubber wheel. When the feeding rubber wheel rotates, the fiber web can be transported between the two laying curtains 20. In addition, a driving system is installed on the top of the laying curtain 20, so that when the driving system is started, it can drive the laying curtain 20 to swing back and forth. When the laying curtain 20 swings, it can contact the extension rod 14, thereby squeezing the synchronous cross frame 17 to move to the end away from the support frame 21. When the synchronous cross frame 17 moves, it can drive the rack 15 to move at the first gear 23. The top of the guide frame 28 moves upward, so that the rack 15 can drive the first gear 23 to rotate when it is displaced, and the key at the top of the rack 15 slides in the groove inside the bottom end of the guide frame 28, so that the rack 15 can be supported to move in a straight line. When the first gear 23 rotates, it can drive the connecting base frame 25 and the iron 22 to rotate toward the end away from the supporting frame 21, and the fiber web laid by the net curtain 20 will not interfere with the iron 22. Subsequently, when the net curtain 20 is out of contact with the extension rod 14, the elasticity of the reset spring 18 will drive the synchronous cross frame 17 to reset, and when the synchronous cross frame 17 is reset, it can drive the rack 15 to reset on the first gear 23, so that the first gear 23 can drive the connecting base frame 25 and the iron 22 to rotate and reset. When the iron 22 rotates and resets, the connecting base The bottom end of the frame 25 can contact the top end of the photoelectric sensor 31. At this time, the photoelectric sensor 31 will sense a signal, thereby starting the iron 22. At this time, when the iron 22 is in a horizontal state, it can be located above the conveyor belt 13, so that the iron 22 can press the superimposed fiber webs, and the iron 22 can release high-temperature steam inside, so that the edges of the fiber webs can be ironed to avoid the edge of the fiber webs from warping. At the same time, when the connecting base frame 25 rotates, it can also drive the second gear 26 to rotate at the same time, and the second gear 26 is meshed with the third gear 35, so that the second gear 26 can drive the third gear 35 to rotate. When the third gear 35 rotates, it can drive the synchronous round rod 37 to rotate, and the sleeve rod 32 is slidably inserted in The inside of the sleeve plate 4 allows the synchronous round rod 37 to be driven by the third gear 35 to drive the sleeve plate 4 to move up and down, and the displacement bracket 8 is slidably sleeved on the vertical column 7, so that the contact plate 5 can be guaranteed to move up and down in a straight line. When the contact plate 5 moves downward, it can press the fiber web being transmitted on the conveyor belt 13, so that the fiber web can be compacted. At the same time, when the rack 15 returns to its original position, it can drive the second gear 26 and the third gear 35 to rotate and reset at the same time, so that the synchronous round rod 37 can drive the sleeve rod 32 to rotate upward, thereby supporting the contact plate 5 to remain suspended and placed, which is convenient for the conveyor belt 13 to drive the fiber web to transmit. When the device is in use, the setting of the guide plate 3 can assist the fiber web to move along the surface of the guide plate 3 to between the laying curtains 20. At the same time,Two groups of sleeve plates 4, contact plates 5, supporting side frames 6, vertical columns 7 and displacement brackets 8 are arranged on the supporting side frames 12, and the two sleeve rods 32 are arranged with different lengths. The two sleeve rods 32 are respectively inserted into the separate sleeve plates 4, so that when the laying curtain 20 moves back and forth, it can drive the second gear 26 and the third gear 35 to rotate, so that the contact plate 5 can press up and down reciprocally to improve the pressing tightness of the fiber web. At the same time, when the iron 22 rotates to a vertical state, it will not contact the synchronous horizontal frame 17, so that the iron 22 can avoid interference with the synchronous horizontal frame 17. When the net-laying curtain 20 has not swung to the limit position, the iron 22 can be rotated 90°, so that the fiber net laid by the net-laying curtain 20 can be prevented from interfering with the iron 22, so that the fiber net can be laid flat on the conveyor belt 13. At the same time, when the connecting base 25 is rotated upward, it can be separated from the photoelectric sensor 31, so that the photoelectric sensor 31 will lose the sensing signal, causing the iron 22 to lose power, thereby reducing energy consumption. At the same time, the bottom end of the iron 22 is attached to the top of the fiber net, and the edge of the fiber net can be pressed to avoid the phenomenon of warping when the fiber net is superimposed, and the work is completed.

[0039] Example 2

[0040] On the basis of Example 1, Fig.10 As shown, the guide plate 3 includes a limiting side plate 38, a supporting back plate 39 and a hydraulic cylinder 40. The supporting back plate 39 is symmetrically fixedly installed on the side end of the guide plate 3, the hydraulic cylinder 40 is symmetrically fixedly installed on the supporting back plate 39, and the limiting side plate 38 is fixedly installed on the side end of the hydraulic cylinder 40 close to the guide plate 3.

[0041] When implementing this embodiment, when the fiber web is transmitted along the surface of the guide plate 3, the hydraulic cylinder 40 can be started to drive the limiting side plate 38 to move, so that the distance between the two limiting side plates 38 can be controlled, thereby adapting to the transmission of fiber webs of different widths. At the same time, by locating the limiting side plates 38 on both sides of the fiber web, the fiber web can be prevented from being skewed during transmission, thereby completing the work.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
