The mesh curtain is laid on the frame, and also includes a limiting pulley, which is arranged on both sides of the mesh curtain. The limiting pulley is movably connected to the frame. The cross-section of the limiting pulley is I-shaped, and an annular groove is provided on the limiting pulley for clamping the mesh curtain to prevent deviation; the deviated mesh curtain contacts the inner surface of the groove of the rotating limiting pulley to generate a reaction force, so that the mesh curtain moves in the opposite direction, thereby realizing the correction of the mesh curtain. The rotating limiting pulley contacts the mesh curtain, the friction is small, and the wear on the mesh curtain is small.

[0004] When the above technology is in use, a certain degree of deviation correction effect is provided to the mesh curtain by setting limiting pulleys on both sides of the mesh curtain and moving the limiting pulleys. However, in actual use, since it needs to be adjusted manually by personnel, the burden on the operator is increased, and the mesh curtain cannot be corrected in a timely and accurate manner. Therefore, in order to solve the above technical problems, we proposed a non-woven fabric web-forming machine. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-7 A nonwoven fabric web-forming machine comprises a mounting frame 1 and a web-forming device body 2 mounted on one side of the upper surface of the mounting frame 1, a net curtain 4 is connected to the inner side of the mounting frame 1 through electric rollers 3 at both ends, a guide rod 5 is symmetrically mounted in the middle of the inner side of the mounting frame 1, a movable seat 6 is slidably mounted on the guide rod 5, the inner side of the mounting frame 1 is connected to the movable seat 6 through an electric cylinder 7, upper columns 8 are arranged at both ends of the upper surface of the movable seat 6, a first pulley 9 is arranged on the column body of the upper column 8 corresponding to the side of the net curtain 4, and a deviation correction sensor 10 is installed on one side of the lower side surface of the mounting frame 1.

[0028] Example 2

[0029] Reference Figure 1-7, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] Lower columns 11 are installed at both ends of the lower surface of the moving seat 6, and a second pulley 12 is installed on the column of the lower column 11. The arrangement of the lower column 11 and the second pulley 12 enables the moving seat 6 to drive the two first pulleys 9 to correct the net curtain 4, and the two second pulleys 12 can also correct the net curtain 4, that is, improve the correction effect on the net curtain 4; the ends of the two ends of the moving seat 6 are installed with connecting plates 14 through screws 13, and the upper column 8 and the lower column 11 are installed at the upper and lower ends of the connecting plate 14 The setting of the connecting plate 14 and the screws 13 allows personnel to easily disassemble the upper column 8 and the lower column 11, which is convenient for maintenance of the first pulley 9 and the second pulley 12; guide plates 15 are installed at both ends of the upper surface of the movable seat 6, and the upper ends of the guide plates 15 extend to the upper surface of the mesh curtain 4. The setting of the guide plates 15 is convenient for guiding and limiting the non-woven fabric transported on the upper surface of the mesh curtain 4, that is, to avoid the non-woven fabric from being unstable when moving on the mesh curtain 4, thereby affecting the subsequent winding phenomenon.

[0031] A mounting plate 16 is installed on the frame of the mounting frame 1 corresponding to the guide rod 5. The two mounting plates 16 are respectively fixed at the two ends of the guide rod 5, and the electric cylinder 7 is installed on the inner side of one of the mounting plates 16. The setting of the mounting plate 16 is convenient for personnel to disassemble and install the guide rod 5 and the movable seat 6, so as to facilitate personnel to maintain the parts; a fixing block is fixed in the middle of one side of the movable seat 6, the output end of the electric cylinder 7 is connected to one side of the fixing block, and the other side of the fixing block is connected to a guide rod 17, and the rod body of the guide rod 17 is sleeved with The guide cylinder 18, one end of the guide cylinder 18 away from the fixed block is fixed on the plate body of the mounting plate 16, and the setting of the guide rod 17 and the guide cylinder 18 further improves the stability of the moving seat 6 when it moves; wiping rings 19 are provided at both ends of the moving seat 6, and the wiping ring 19 is sleeved on the outer ring surface of the guide rod 5. The setting of the wiping ring 19 can block the junction between the guide rod 5 and the moving seat 6, so that fibers and other debris on the surface of the external bulk material enter the interior of the moving seat 6, thereby ensuring the stability of the moving seat 6 when it moves.

[0032] Principle and advantages of use: During the use of the utility model, fiber filaments are sprayed from the main body 2 of the web-forming device to the upper surface of the net curtain 4, and the fiber filaments are accumulated on the upper surface of the net curtain 4. Then, as the net curtain 4 slowly runs, the fiber filaments are piled on the upper surface of the net curtain 4 into a cloth-like material with a certain thickness, i.e., a non-woven fabric. Subsequently, the non-woven fabric moves to subsequent procedures under the transportation of the net curtain 4, so as to finally complete the overall production and processing of the non-woven fabric. In the above process, the net curtain 4 is inevitably deviated during the continuous operation, i.e., in this method, the net curtain 4 is deviated. In the case, the position of the net curtain 4 is monitored by the deviation correction sensor 10, and when the position of the net curtain 4 deviates beyond the range, the electric cylinder 7 can be automatically controlled by the program set by the equipment, or manually controlled by personnel, that is, the output end of the electric cylinder 7 drives the moving seat 6 to move, and when the moving seat 6 moves, it drives the first pulleys 9 at both ends to move synchronously, that is, the first pulley 9 at one end applies a certain degree of pressure to the side of the net curtain 4, so that the net curtain 4 moves gradually along the pressure direction, thereby realizing the deviation correction of the net curtain 4.

[0033] In summary, with the mutual cooperation of the above-mentioned components, when this solution is used, the two first pulleys 9 are driven to move by the electric cylinder 7 and the movable seat 6, so that the side of the net curtain 4 is pushed by the first pulley 9, thereby achieving the effect of correcting the deviation of the net curtain 4. Compared with the traditional solution in which personnel manually adjust the limit pulley, when this solution is used, the position of the net curtain 4 is monitored in real time by the correction sensor 10, so as to timely obtain whether the net curtain 4 is deviated, and the first pulley 9 is moved quickly and accurately by the electric cylinder 7, thereby achieving the effect of adjusting the position of the net curtain 4, that is, solving the defects of the traditional solution, which has large manpower expenditure, untimely, inconvenient and inaccurate correction of the position of the net curtain 4.

[0034] It should be further explained that the arrangement of the lower column 11 and the second pulley 12 enables the two second pulleys 12 to correct the net curtain 4 when the movable seat 6 drives the two first pulleys 9 to correct the net curtain 4, that is, the correction effect on the net curtain 4 is improved; the arrangement of the connecting plate 14 and the screw 13 enables personnel to conveniently disassemble the upper column 8 and the lower column 11, that is, to facilitate the maintenance of the first pulley 9 and the second pulley 12; the arrangement of the guide plate 15 is convenient for the surface of the net curtain 4 The nonwoven fabric conveyed on the surface is guided and limited; the setting of the mounting plate 16 is convenient for personnel to disassemble and install the guide rod 5 and the movable seat 6, so as to facilitate personnel to maintain the parts; the setting of the guide rod 17 and the guide cylinder 18 further improves the stability of the movable seat 6 when it moves; the setting of the wiping ring 19 can shield the junction between the guide rod 5 and the movable seat 6, so that the fibers and other debris of the external bulk material on the surface enter the interior of the movable seat 6, which ensures the stability of the movable seat 6 when it moves.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
