Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to a mesh driving roller device for a triple mesh multi-drying cylinder papermaking machine. Background Art

[0002] The wire drive roller is a key component used to drive the wire to rotate in the papermaking machine. In the papermaking process, the wire is responsible for supporting the wet pulp and forming paper sheets on its surface. The wire drive roller ensures that the wire can move evenly through contact with the wire, thereby helping to achieve smooth transportation and dehydration of the paper sheets. The wire drive roller is usually used in conjunction with a vacuum roller, which further enhances the dehydration effect of the wet pulp through vacuum suction.

[0003] A mesh-driving roller is required in the papermaking production process. The mesh-driving roller needs to be removed for maintenance after a certain period of use. When the mesh-driving roller is removed, the staff needs to use handheld tools to remove the bolts. The operation steps are cumbersome and troublesome, which reduces the subsequent maintenance efficiency of the mesh-driving roller. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a mesh driving roller device for a triple mesh multi-drying cylinder papermaking machine.

[0006] Through the above technical scheme, by pulling the handle, the fixed plate is driven to move, and the fixed plate pulls the fixed rod to move, so that the limit ring squeezes the reset spring, so that the reset spring is compressed, and at the same time the limit plate is driven to move into the avoidance groove, and the limit on the L-shaped plate is cancelled. Then the limit seat is removed, and the limit on the driving net roller is cancelled. The driving net roller can be quickly disassembled for inspection and maintenance, and the operation is convenient and quick, which improves the maintenance efficiency of the driving net roller and is conducive to the subsequent rapid installation of the driving net roller.

[0007] As a further improvement of the above solution, the inner walls of the mounting seat and the limiting seat are both provided with arc grooves, and the right end of the mounting frame is fixedly connected to the left end of the mounting seat.

[0008] Through the above technical solution, the driving screen roller is limited by the arc grooves of the mounting seat and the limiting seat.

[0009] As a further improvement of the above solution, the number of the mounting seats is two, and the right end of the return spring is in contact with the left end of the limiting ring.

[0010] Through the above technical solution, the limit ring is pushed by the elastic reset of the reset spring, thereby driving the fixing rod to move.

[0011] As a further improvement of the above solution, one end of the return spring away from the limiting ring is fixedly connected to the inner wall of the mounting bracket, and the inner wall of the mounting seat is provided with a plug-in groove.

[0012] As a further improvement of the above solution, the L-shaped plate is plugged into the plug-in slot, and an avoidance slot is provided on the inner wall of the mounting seat.

[0014] As a further improvement of the above solution, the avoidance groove is adapted to the size of the limiting plate, and the surface of the limiting plate is in contact with the inner wall of the L-shaped plate.

[0015] Through the above technical solution, the limiting plate is prevented from contacting the L-shaped plate by the avoidance groove, thereby eliminating the limitation of the L-shaped plate.

[0016] As a further improvement of the above solution, a motor is arranged at the upper end of the fixed bottom plate, a transmission shaft is fixedly connected to the output end of the motor, and the inner wall of the transmission shaft is plugged into the right end of the driving net roller.

[0017] Through the above technical solution, the transmission shaft is plugged into the spline groove of the driving roller through the spline on the inner wall.

[0018] As a further improvement of the above solution, a mounting bracket is fixedly connected to the bottom of the motor, and the bottom of the mounting bracket is fixedly connected to the upper surface of the fixed base plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model provides a limit seat, an L-shaped plate, a limit plate, a fixing rod, a limit ring, a reset spring, a mounting frame, a fixing plate and a handle. Specifically, when the mesh driving roller needs to be disassembled and maintained, the handle is pulled to drive the fixing plate to move, so that the fixing plate pulls the fixing rod to move, so that the limit ring squeezes the reset spring, so that the reset spring is compressed, and at the same time drives the limit plate to move into the inside of the avoidance groove, cancels the limit on the L-shaped plate, and then the limit seat is removed, cancels the limit on the mesh driving roller, and the mesh driving roller can be quickly disassembled for inspection and maintenance, and the operation is convenient and quick, thereby improving the maintenance efficiency of the mesh driving roller and improving practicality.
