Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a walking limiting structure of a papermaking felt base net for a jointing machine. Background Art

[0002] The base mesh of papermaking felt is a key component used in papermaking machinery jointers. The structure of papermaking felt is mainly composed of fiber layer, mesh belt structure and edge treatment, and its main function is to be used for pressing and dehydration. In the papermaking process, when the wet paper web passes through the papermaking felt, the felt can effectively remove excess water from the wet paper web by virtue of its excellent water absorption and air permeability. At the same time, the fiber layer and mesh belt structure of the felt can also level and press the wet paper web, making the paper more uniform and compact. The base mesh of papermaking felt is the core component of the papermaking felt. It carries the main structure and function of the felt. The existence of the base mesh not only enhances the overall strength of the papermaking felt, but also provides it with good support and stability, so that the felt can maintain stable performance in a high-speed papermaking machine.

[0003] The travel limit of the papermaking felt base net is one of the key designs to ensure its stable operation in the papermaking machinery. During the papermaking process, the felt base net needs to move continuously along the set path to cooperate with other process links to achieve continuous production of paper. The design of the travel limit is to ensure that the base net can move along the predetermined trajectory to prevent it from deviating or shifting. At present, for the travel limit of the papermaking felt base net, only a single guide wheel structure is used, and the limiting effect is insufficient, and the base net is prone to deviation. In view of this, the present application proposes a travel limit structure for the papermaking felt base net for a jointing machine. Utility Model Content

[0004] The utility model aims to provide a base net travel limiting structure for a papermaking felt used in a jointing machine, which has a good limiting effect on the travel of the base net and is highly flexible and suitable for limiting the travel of base nets of different widths.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a walking limiting structure for a papermaking felt base net for a jointing machine, comprising a mounting plate, a pair of the mounting plates are arranged side by side; an axle rod horizontally rotatably installed between the pair of mounting plates, the axle rod being provided with a guide wheel; and a side baffle plate arranged on the opposite sides of the pair of mounting plates, the side baffle plate being located above the axle rod, and the top of the side baffle plate being higher than the top of the guide wheel.

[0006] Preferably, a plurality of shaft rods are evenly arranged side by side, and a plurality of guide wheels are evenly mounted on each shaft rod.

[0007] Preferably, a screw rod is threadedly provided on the mounting plate, the screw rod is rotatably connected to the side baffle plate, and a rotary block is fixed to one end of the screw rod away from the side baffle plate.

[0008] Preferably, the screw rod is located in the middle of the mounting plate, and guide rods are movably provided at both ends of the mounting plate, and the guide rods are fixedly connected to the side baffles.

[0009] Preferably, a rubber ring is mounted on the guide wheel.

[0010] Preferably, a sleeve is fixed on the end surface of the guide wheel, and the guide wheel and the sleeve are movably mounted on the shaft rod. A positioning bolt that can be tightly pressed against the shaft rod is threaded through the sleeve.

[0011] Preferably, a groove is formed on one side of the side baffle away from the mounting plate, a roller is vertically rotatably mounted in the groove, a plurality of rollers are provided, and the rollers protrude out of the groove.

[0012] Preferably, a support block is fixed to the bottom of the opposite sides of a pair of mounting plates, a bearing bush is fixed to the top of the support block by bolts, and the end of the shaft rod is rotatably embedded between the support block and the bearing bush.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model utilizes a plurality of guide wheels on a plurality of shafts to continuously guide the base net of the papermaking felt. During the guiding process, a pair of side baffles on the opposite sides of the mounting plates can limit the two sides of the base net to ensure that the base net can move along a predetermined trajectory and prevent it from deviating or shifting, thereby prompting the papermaking felt to continuously move along the set path to cooperate with other process links to achieve continuous production of paper.

[0015] The rubber sleeve provided on the guide wheel can reduce the wear caused by hard contact. In addition, the plurality of rollers provided on the side baffles can make the base net and the side baffles roll in contact, thereby reducing friction resistance and improving the limiting effect.

[0016] By turning the rotary block to drive the screw rod to rotate, the spacing between a pair of side baffles can be adjusted under the guidance of the guide rod, which is suitable for base net travel limits of different widths. The bolt connection between the support block and the bearing shell facilitates the assembly of the shaft rod, and the positioning of the sleeve by the positioning bolt facilitates the assembly of the guide wheel. At the same time, the number of guide wheels can be increased or decreased, and the density of the guide wheels can be adjusted to adapt to the travel limits of base nets of different widths.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
