Abstract
Description
Technical Field
[0001] This utility model relates to the field of continuous press technology, and in particular to an axial fixing and anti-loosening device for a chain drive sprocket seat of a continuous press. Background Technology
[0002] Traditional continuous presses for engineered wood products (including but not limited to particleboard, fiberboard, and plywood) use two (but not limited to) set screws to axially fix the chain drive sprocket seat (including but not limited to chain drive sprocket seat and toothed sprocket seat). Figure 1 As shown in the figure, this fixing method is prone to loosening during long-term operation. Even with the addition of anti-loosening agents, it will still loosen after long-term use due to changes in the working environment temperature, causing the sprocket position to move axially and interrupting the continuous production of the continuous press production line. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an axial fixing and loosening device for a continuous press chain drive sprocket seat, in order to prevent the set screw from loosening, addressing the problems existing in the prior art.
[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0005] An axial fixing and anti-loosening device for a continuous press chain drive sprocket seat includes a sprocket shaft, several sprocket seats, and several sprockets. Each of the several sprocket seats is axially fixed to the sprocket shaft by at least two set screws. Each sprocket is mounted on the corresponding sprocket seat by a mounting bolt. The device is characterized in that a hole is opened in the head of each set screw, and a steel wire is passed through the holes of all the set screws and the two ends of the steel wire are fixed together.
[0006] In a preferred embodiment of this utility model, the two ends of the steel wire are wound together in a figure-eight shape.
[0007] In a preferred embodiment of this utility model, the two ends of the steel wire are fixed together by welding.
[0008] By adopting the above technical solution, this utility model can prevent the set screw from loosening, making long-term operation of the continuous press possible, thereby greatly improving the reliability of the chain drive of the continuous press, and at the same time greatly improving the output and quality of the products produced by the continuous press. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the axial fixing and anti-loosening device for the continuous press chain drive sprocket seat of this utility model.
[0010] Figure 2 for Figure 1AA sectional view. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0012] See Figure 1 and Figure 2 The figure shows an axial fixing and anti-loosening device for a continuous press chain drive sprocket seat, including a sprocket shaft 100, several sprocket seats 200 and several sprockets 300. Each of the several sprocket seats 200 is axially fixed to the sprocket shaft 100 by two set screws 410 and 420 (or more than two). Each sprocket 300 is mounted on the corresponding sprocket seat 200 by a mounting bolt 510.
[0013] The features of this utility model are: the set screws 410 and 420 are slightly longer than existing set screws, and each set screw 410 and 420 has a hole 411 or 421 in its head. A steel wire 500 is passed through the holes 411 or 421 of the set screws 410 and 420, and the two ends of the steel wire 500 are wrapped together in a figure-eight shape. Of course, the two ends of the steel wire 500 can also be fixed together by welding or other methods known to those skilled in the art.
[0014] This invention ensures that the set screws 410 and 420 will not loosen by pulling with the steel wire 500.
