[0002] The mesh tightening device is a component of the papermaking machine mesh. It is a device used to adjust the tension of the mesh (blanket) and is also an important tool to ensure the normal operation of the mesh (blanket). When in use, the operator can adjust the position of the tensioning roller in the mesh tightening device according to actual needs, thereby adjusting the tension of the mesh (blanket) by changing the position of the tensioning roller. However, most of the existing mesh tightening devices still adopt manual adjustment, which is cumbersome, labor-intensive and time-consuming to operate, and has low adjustment accuracy. In the actual adjustment process, it is often necessary to perform repeated adjustments and start-up tests before the mesh tightening roller can be adjusted in place, which seriously affects the production efficiency of the papermaking equipment. In order to solve the above problems, it is necessary to develop a mesh tightening device for papermaking equipment with a stable and reasonable overall structural design and efficient and convenient adjustment operation.

Its upper end is vertically fixed to the lower surface of the support plate 12. The vertical rod 151 is located directly below the sleeve 152. Its lower end is fixed to the upper surface of the fixed bottom plate 11. The upper end is slidably arranged inside the sleeve 152. A card slot 153 is provided on both sides of the upper end of the vertical rod 151. An electric rod is provided in the card slot 153 for horizontal sliding. Magnet 154; a placement groove 121 is provided in the middle of the upper surface of the support plate 12, and slide grooves 122 are horizontally provided on both sides of the upper surface. A plurality of pressure sensors 123 are provided on the bottom surface of the placement groove 121, and a slide plate 124 is provided for sliding inside the slide groove 122, and a threaded through hole 125 is connected to the outside. The middle part of the lower end of the slide plate 124 is horizontally rotated and penetrated with a connecting shaft 126, and the upper end protrudes from the slide groove 122 and is located above the support plate 12 and is vertically fixedly connected to the limited pressure plate 16; the threaded through hole 125 is arranged horizontally as a whole, and its internal thread rotationally penetrates a threaded rod 127, and the threaded rod 127 is concentrically fixedly connected to the connecting shaft 126; the support rod 13 is located above the support plate 12, and its upper end is longitudinally rotated and penetrated with a rotating shaft 17, and the lower end is fixedly connected to a placement block 18 that matches the placement groove 121 structure. The tensioning roller 2 is longitudinally arranged between the rotating shafts 17 in the two mounting supports 1 and is concentrically fixedly connected to the rotating shaft 17.
[0020] The front end surface of the vertical rod 151 is evenly provided with scale lines from bottom to top, and the scale lines can increase the accuracy of the movement of the support plate 12, the support rod 13 and the tensioning roller 2 under the action of the airbag 14; the outer side surface of the electromagnet 154 is arc-shaped, and the arc-shaped structure can increase the contact area between the electromagnet 154 and the inner wall of the iron sleeve 152, thereby improving the tightness of the connection between them after the electromagnet 154 is energized; the outer end of the threaded rod 127 is concentrically fixed with a square auxiliary rotating block, and the square auxiliary rotating block can increase the convenience of the rotation operation of the screw rod 127; the mounting bracket 1 also includes a controller 19, which is fixed to the front end of the support plate 12, and the electromagnet 154 and the pressure sensor 123 are both electrically connected to the controller 19.

[0021] During the use of the present invention, when it is necessary to adjust the tension of the net (blanket), first, the power circuit of the electromagnet 154 is cut off by the controller 19, thereby releasing the limit connection between the vertical rod 151 and the sleeve 152, and then the air bag 14 is inflated by the air pump. At this time, the guiding effect achieved by the sliding sleeve connection between the vertical rod 151 and the sleeve 152 in the guide assembly 15, combined with the characteristics of the inflation and expansion of the air bag 14, can be used to adjust the position of the support plate 12 and the support rod 13 and the tensioning roller 2 located above the support plate 12, and then the change in the position of the tensioning roller 2 can be used to adjust the tension of the net (blanket).
