[0021] The effect achieved by the entire Embodiment 1 is that U-shaped support plates 3 are fixedly connected to the top of the bottom plate 1 and near both ends. The top of the U-shaped support plate 3 is fixedly connected to the top plate 4, which can support the bottom of the top plate 4. A headbox 5 is fixedly connected to the top of the top plate 4 and near one end. A stuff box 8 is installed on the inner wall of the top of the headbox 5, which can make the circulating pump send the mixed liquid of water and glass fiber into the headbox 5. The slurry is uniform in the headbox 5. At this time, it is then distributed on the conveyor belt through the stuff box 8 to form a felt blank. Baffles 6 are fixedly connected to the top of the top plate 4 and near both ends inside the headbox 5. A filter screen 7 is fixedly connected between the baffles 6 and near the top, which can filter and collect the pulp water.

The output ends of the electric push rods 18 are fixedly connected to convex plates 16. The protruding parts of the convex plates 16 are respectively embedded and rotatably connected to forming rollers 17 through bearings, which can push the convex plates 16 to rise by the electric push rods 18. The rising of the convex plates 16 drives the forming rollers 17 to rise, which can squeeze the conveyor belt, so as to achieve the effect of making the conveyor belt become tight again. An inclined screen forming box 24 is installed under the headbox 5 at the bottom of the top plate 4, which can form the felt blank.

[0022] Embodiment 2, as Figures 1-3 shown, support legs 2 are fixedly connected to the bottom of the bottom plate 1 and near the four corners. The shape of the support legs 2 is trapezoidal; fixing plates 9 and first U-shaped plates 12 are respectively fixedly connected to both ends of the top plate 4. U-shaped members 10 are fixedly connected to the top and bottom of the fixing plate 9. A first roller 11 and a second roller 13 are respectively rotatably connected to the inside of the U-shaped member 10 and the first U-shaped plate 12 through bearings; support columns 19 are symmetrically fixedly connected to the top of the top plate 4 and near one end. V-shaped plates 20 are fixedly connected to the tops of the support columns 19. A fifth roller 21 is rotatably connected between the V-shaped plates 20 and near both ends through bearings; a second U-shaped plate 22 is fixedly connected to the top of the top plate 4 and near the first U-shaped plate 12. A distribution roller 23 is rotatably connected to the inside of the second U-shaped plate 22 through a bearing; a third roller 14 is rotatably connected to the inside of the U-shaped support plate 3 through a bearing.

[0023] The effects achieved by the entire Embodiment 2 are as follows: Support legs 2 are fixedly connected to the bottom of the bottom plate 1 near the four corners. The shape of the support legs 2 is trapezoidal, which can support the four corners at the bottom of the bottom plate 1. Fixed plates 9 and first U-shaped plates 12 are respectively fixedly connected to both ends of the top plate 4. U-shaped members 10 are fixedly connected to both the top and bottom of the fixed plate 9. A first roller 11 and a second roller 13 are respectively rotatably connected to the inside of the U-shaped member 10 and the first U-shaped plate 12 by bearings, which can convey the conveyor belt. Support columns 19 are symmetrically and fixedly connected to the top of the top plate 4 near one end. V-shaped plates 20 are fixedly connected to the tops of the support columns 19. Fifth rollers 21 are rotatably connected to the inside of the V-shaped plates 20 near both ends by bearings, which can convey the conveyor belt into the pre-mesh box 5. A second U-shaped plate 22 is fixedly connected to the top of the top plate 4 near the first U-shaped plate 12. A distribution roller 23 is rotatably connected to the inside of the second U-shaped plate 22 by a bearing, which can distribute the wet glass fiber. Third rollers 14 are rotatably connected to the inside of the U-shaped support plates 3 by bearings, which can convey the conveyor belt from the inside of the U-shaped support plates 3.

[0024] Working principle: The mixed liquid of water and glass fiber is sent into the pre-mesh box 5 through a circulating pump. At this time, it is evenly distributed on the inclined long conveyor belt through the headbox 8 in the pre-mesh box 5, and the fibers are deposited to form a felt blank. The excess water will fall through the filter screen 7 and enter between the baffles 6. At this time, the rollers rotate to convey the conveyor belt. When the conveyor belt passes under the inclined mesh forming box 24 and on the forming roller 17 for forming, and when the conveyor belt conveyed on the surface of the roller becomes loose, the electric push rod 18 can be used to push the convex plate 16 to rise. The rising of the convex plate 16 drives the forming roller 17 to rise, which can squeeze the conveyor belt, so as to make the conveyor belt become tight again, and then improve the conveying effect.

[0025] The wiring diagrams of the pre-mesh box 5, the headbox 8, the electric push rod 18, the distribution roller 23, and the inclined mesh forming box 24 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the pre-mesh box 5, the headbox 8, the electric push rod 18, the distribution roller 23, and the inclined mesh forming box 24 will not be explained in detail.
