Description

Technical Field

[0001] The utility model relates to the technical field of paper machines, and specifically discloses a forming wire support element for a paper machine. Background Technique

[0002] The forming wire of a paper machine, namely a sheet former, is an endless wire on which the pulp suspension is dewatered to form a paper web, cardboard or pulp board. The forming wire is a valuable equipment for papermaking and is divided into two categories: metal wire and plastic wire.

[0003] During the movement of the existing forming wire following the rotation of the support roller, it is prone to deviation, resulting in the support roller being unable to effectively position the forming wire, and the support roller being unable to be applicable to forming wires of different widths. Summary of the Utility Model

[0004] In view of the above defects or deficiencies in the prior art, the present application aims to provide a forming wire support element for a paper machine, including a frame, a support roller rotatably connected inside the frame, and a forming wire sleeved outside the support roller. An adjusting mechanism is sleeved inside the frame, and a first fixing plate and a second fixing plate located outside the support roller are sleeved outside the adjusting mechanism. A slewing bearing located outside the support roller is fixedly installed inside both the first fixing plate and the second fixing plate through bolts, and a limiting sleeve movably sleeved outside the support roller is fixedly installed inside the slewing bearing through bolts. A pressing mechanism is arranged at the top of the second fixing plate.

[0005] Preferably, the adjusting mechanism includes a guide rod fixedly sleeved inside the frame and movably sleeved inside the first fixing plate and the second fixing plate, and a bidirectional lead screw rotatably connected inside the frame and threadedly sleeved inside the first fixing plate and the second fixing plate. A turntable is fixedly sleeved outside one end of the bidirectional lead screw extending outside the frame, and a limiting rod located outside the frame is threadedly sleeved inside the turntable.

[0006] Preferably, the pressing mechanism includes a fixing rod arranged at the top of the second fixing plate, a fixing frame is clamped outside the fixing rod, a pressing wheel located above the support roller is rotatably connected outside the fixing frame, and first nuts and second nuts are respectively threadedly sleeved outside the top end and the bottom end of the fixing frame.

[0007] Preferably, a limiting boss adapted to the fixing rod is arranged inside the fixing frame.

[0008] Beneficial Effects:

[0009] 1. The forming wire support element of the paper machine can limit both sides of the forming wire through the limiting sleeve, so that the forming wire will not shift during the process of moving following the rotation of the support roller. And through the turntable, the bidirectional lead screw can be rotated while driving the first fixed plate and the second fixed plate to move in the opposite direction, and then the distance between the two limiting sleeves can be adjusted according to the width of the forming wire, so that the support element can effectively position the forming wire, and it can be applicable to forming wires of different widths.

[0010] 2. The forming wire support element of the paper machine can press and limit both sides of the forming wire through the pressing wheels, preventing the two sides of the forming wire from warping during the moving process. And the distance between the pressing wheels and the support roller can be adjusted by loosening the first nut and the second nut, so that the support element can be applicable to forming wires of different thicknesses.

[0017] The following further details the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0018] The accompanying drawings in the embodiments of the present utility model: Different types of hatching lines in the figures are not marked according to the national standard, nor are there requirements for the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the figures.

[0019] Please refer to Figures 1-4 , a forming wire support element for a paper machine, comprising a frame 1, a support roller 2 rotatably connected inside the frame 1, and a forming wire 3 sleeved outside the support roller 2. An adjusting mechanism 4 is sleeved inside the frame 1. A first fixing plate 5 and a second fixing plate 6 located outside the support roller 2 are sleeved outside the adjusting mechanism 4. Inside the first fixing plate 5 and the second fixing plate 6, a swing bearing 8 located outside the support roller 2 is fixedly installed through bolts 7. Inside the swing bearing 8, a limiting sleeve 9 movably sleeved outside the support roller 2 is fixedly installed through bolts 7. Through the swing bearing 8, the limiting sleeve 9 can rotate around its own axis, and at the same time, the two sides of the forming wire 3 can be limited through the limiting sleeve 9, that is, when the limiting sleeve 9 contacts the support roller 2, the limiting sleeve 9 can rotate following the movement of the support roller 2, thereby reducing the wear between the two. A pressing mechanism 10 is arranged on the top of the second fixing plate 6.

[0020] Among them, the adjusting mechanism 4 includes a guide rod 41 fixedly sleeved inside the frame 1 and movably sleeved inside the first fixing plate 5 and the second fixing plate 6, and a bidirectional lead screw 42 rotatably connected inside the frame 1 and threadedly sleeved inside the first fixing plate 5 and the second fixing plate 6. Through the guide rod 41, the first fixing plate 5 and the second fixing plate 6 can be limited and guided, so that under the rotation of the bidirectional lead screw 42, the first fixing plate 5 and the second fixing plate 6 can move synchronously in the opposite direction along the axis of the guide rod 41, thereby adjusting the distance between the two limiting sleeves 9. One end of the bidirectional lead screw 42 extending outside the frame 1 is fixedly sleeved with a turntable 43. A limiting rod 44 located outside the frame 1 is threadedly sleeved inside the turntable 43. By tightening the limiting rod 44, the turntable 43 can be limited and fixed, so that the turntable 43 will not rotate by itself, thereby ensuring that the limiting sleeve 9 can stably position the forming wire 3.

[0021] Among them, the pressing mechanism 10 includes a fixing rod 101 arranged on the top of the second fixing plate 6. A fixing frame 102 is clamped outside the fixing rod 101. A pressing wheel 103 located above the support roller 2 is rotatably connected outside the fixing frame 102. First nuts 104 and second nuts 105 are respectively threadedly sleeved outside the top end and the bottom end of the fixing frame 102. By loosening the first nut 104 and the second nut 105, the distance between the pressing wheel 103 and the support roller 2 can be adjusted, so that the support element can fix the pressing wheel 103 according to the thickness of the support roller 2, ensuring that the pressing wheel 103 will not cause excessive extrusion on the support roller 2.

[0022] Among them, a limiting boss 11 adapted to the fixing rod 101 is arranged on the inner side of the fixing frame 102. The fixing frame 102 can be limited and guided through the limiting boss 11, so that the pressing wheel 103 will not rotate around the axial direction of the fixing rod 101, thereby ensuring that the pressing wheel 103 can support and squeeze both sides of the supporting roller 2 and preventing the supporting roller 2 from warping.

[0023] When the support element is adjusted, the bidirectional lead screw 42 is rotated through the turntable 43 according to the width of the support roller 2, and at the same time, the first fixing plate 5 and the second fixing plate 6 are driven to move in the opposite direction. After the distance between the two limiting sleeves 9 is adjusted, the first nut 104 and the second nut 105 are loosened according to the thickness of the support roller 2. After the distance between the pressing wheel 103 and the support roller 2 is adjusted, the first nut 104 and the second nut 105 are tightened to complete the adjustment of the support element.
