Description

Technical field:

[0001] The utility model relates to a diamond roller driven belt tensioning device. Background technology:

[0002] In the board making industry, mechanical paving and forming usually adopts diamond roller paving, and the roller surface is processed into a diamond shape. The raw materials are sorted through the gap between the rollers to form artificial particleboards with different cross sections. At present, diamond roller transmission adopts synchronous toothed belt transmission. During the production process, the material often falls on the synchronous toothed belt or pulley, so the synchronous toothed belt breaks. The tensioning roller must be removed and the entire synchronous toothed belt must be replaced. When reinstalling a new synchronous toothed belt, it is very difficult to put the synchronous toothed belt on the tensioning roller. It is usually necessary to remove the mounting seat of the tensioning roller from the frame and adjust the position left and right. However, because the space where the tensioning roller is installed is relatively small, it is very inconvenient to manually remove the mounting seat of the tensioning roller and adjust the position left and right. It takes a long time, which greatly increases the replacement time of the synchronous toothed belt and affects production efficiency. For this reason, it is necessary to improve the above technical problems, and this case is born. Utility model content:

[0006] Furthermore, the front end surface of the central shaft is provided with an operating hole adapted to fit with a hexagonal wrench.

[0007] Furthermore, a mounting seat is fixed to the rear end of the roller seat, and the mounting seat is locked on the frame via fasteners around it.

[0009] Furthermore, the axle of the transition synchronous toothed belt pulley is installed on a vertical connecting rod, the upper end of the vertical connecting rod is connected to the output shaft of a longitudinally arranged adjusting motor, and the adjusting motor drives the transition synchronous toothed belt pulley to swing left and right through the vertical connecting rod; the adjusting motor is fixed to the frame through the motor frame.

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] like Figures 1 to 3As shown, the utility model is a diamond roller driven belt tensioning device, comprising a plurality of diamond rollers uniformly spaced in the transverse direction, a synchronous toothed belt pulley 1 is installed at one end of each diamond roller, a synchronous toothed belt 2 is connected between the synchronous toothed belt pulleys 1 of the plurality of diamond rollers, and also comprising a tensioning roller 3 arranged above the right end of the synchronous toothed belt pulleys 1 of the plurality of diamond rollers, the tensioning roller 3 comprising a roller seat 4 fixed to a frame, a tensioning roller body 5 arranged in front of the roller seat 4 and in contact with the back of the synchronous toothed belt 2, the tensioning roller body 5 is threadedly connected with the roller seat 4, that is, the tensioning roller is a split structure composed of a tensioning roller body and a roller seat. The tensioning roller body and the roller seat are threadedly connected, and when a new synchronous toothed belt is installed, there is no need to adjust the position of the roller seat, and the tensioning roller body only needs to be screwed on the roller seat, which greatly improves the convenience of operation, significantly shortens the replacement time of the synchronous toothed belt, and improves production efficiency.

[0018] It should be noted that when tension adjustment is required, it is only necessary to slide a tension roller body with a different roller diameter; since the tension roller body is threadedly connected to the roller seat, the replacement efficiency of the tension roller body is greatly improved.

[0019] In this embodiment, a connecting screw hole extending in the longitudinal direction is provided in the middle of the roller seat 4; the tensioning roller body 5 includes a central shaft 6 and a roller body 7 rotatably sleeved on the outside of the central shaft 6, the outer peripheral side surface of the roller body is in contact with the inner surface (i.e., the smooth surface) of the synchronous toothed belt, and the rear end of the central shaft 6 is provided with a connecting external thread, which is threadedly connected to the connecting screw hole.

[0020] In this embodiment, in order to facilitate the installation and removal of the tension roller body, the front end surface of the central shaft 6 is provided with an operating hole (not shown in the figure) for matching with a hexagonal wrench.

[0021] In this embodiment, a mounting seat 8 is fixed to the rear end of the roller seat 4, and the mounting seat 8 is locked on the frame via fasteners around it.

[0022] In this embodiment, it also includes a transition synchronous toothed belt pulley 9 arranged on the upper left side of the tensioning roller 3, the transition synchronous toothed belt pulley 9 is in contact with the tooth surface of the synchronous toothed belt 2, and the synchronous toothed belt 2 is wound in an S shape between the transition synchronous toothed belt pulley 9 and the tensioning roller 3.

The adjusting motor 11 is fixed to the frame through a motor frame 12. The adjusting motor 11 drives the transition synchronous toothed belt pulley 9 to swing left and right through the vertical connecting rod 10, thereby adjusting the position of the transition synchronous toothed belt pulley, which helps to better adapt to the synchronous toothed belt.

[0024] In this embodiment, the roller shaft of the diamond roller located at the rightmost end is connected to the driving motor.

[0025] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0026] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0027] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
