Description

Technical Field

[0001] The utility model relates to the technical field of filter paper production, in particular to a pressure former. Background Art

[0002] When producing tea filter paper, firstly, suitable wood is selected to make pulp, and the pulp is spread on the papermaking net of the papermaking machine by a papermaking machine, and the width of the laid pulp is controlled by a high-pressure water sprayer on both sides of the spread pulp, thereby controlling the width of the formed paper. Then the staff starts the papermaking machine, so that the papermaking net drives the pulp to move, so that the pulp is squeezed out of water through the pressing equipment and initially formed. The pressing equipment for squeezing water out of the pulp on the general papermaking machine is mostly roller-shaped. When the pulp passes through the roller, the water is naturally squeezed out. However, this method has a short contact time with the pulp and insufficient pressure, resulting in a lot of excess water in the pulp after squeezing. In the production of pulp, the pulp needs to be dried later. When the pulp is subsequently dried, if there is a lot of water inside the pulp, it is easy to affect the subsequent drying efficiency, which is inconvenient. Utility Model Content

The two transmission belts 330 and the connecting mechanism 400 thereon can drive the moving frame 210 to move on the U-shaped plate 100.

[0029] like Figure 4-5As shown, in this embodiment, the connecting mechanism 400 includes a frame 410, and the frame 410 is movably connected to the adjacent transmission belt 330, a U-shaped block 420 is fixedly connected to one side of the frame 410, and one end of both arms of the U-shaped block 420 is fixedly connected to the side wall of the adjacent moving frame 210, a sleeve frame 430 is slidably sleeved on the outer side wall of the U-shaped block 420, and the sleeve frame 430 is rotatably connected to the support rod 431 on both opposite sides, a card slot 411 is opened at both ends of the top and bottom of the frame 410, and two limit frames 450 are fixedly connected to the top and bottom surfaces of the frame 410, and a T-shaped card block 430 is slidably clamped between the two limit frames 450 located on the same side of the frame 410. 40, and the adjacent ends of the two T-shaped blocks 440 are movably sleeved with the adjacent slots 411, the two T-shaped blocks 440 are rotatably connected to the two support rods 431 on one side, the two L-shaped plates 220 are provided with slide slots 222 on one side, the pressure plate 230 is fixedly connected with top blocks 460 on opposite sides, and the two ends of the sleeve frame 430 are fixedly connected with the side walls of the adjacent frame body 410 with rebound springs 432, the inner and outer walls of the two transmission belts 330 are provided with annular grooves 331, and the adjacent ends of the two T-shaped blocks 440 on the same frame body 410 are movably embedded in the two grooves 331 on the adjacent transmission belts 330.
