Disclosure of Invention

In order to solve the problems, the utility model provides the pressing device for the woodworking engraving machine, which can quickly and stably press wood boards with different sizes in the processing process, reduce the vibration of the wood boards, and improve the processing precision and the production efficiency.

The pressing device for the woodworking engraving machine adopts the following technical scheme:

the pressing device comprises a support, wherein a rotating shaft and a pressing mechanism are installed on the support, a movable swing rod is installed on the rotating shaft and connected with the pressing mechanism, a pressing wheel shaft is installed on the movable swing rod, and a pressing wheel is arranged on the pressing wheel shaft.

The revolving shaft is arranged on the bracket through a bearing seat.

And movable swing rods are arranged at two ends of the rotating shaft and are connected through a connecting rod.

The movable swing rod is provided with a roller, the roller is positioned in a roller track on a fixed frame, the fixed frame is hinged on the bracket, and the pressure wheel shaft is arranged on the roller. The pressing mechanism drives the movable swing rod to lift up or press down, so that the roller is driven to roll in the roller path of the fixed frame, and the pressing wheel shaft is driven to move up or down. This is done: on the one hand, very big reduction the frictional resistance that the mechanism received at the during operation, on the other hand, the mount can be according to the corresponding angle of the different changes of processed material thickness, has good flexibility, guarantees that the pressure wheel axle compresses tightly the timber of processing constantly in the in-process of processing, reaches and guarantees the machining precision.

The pressing mechanism adopts a pressing cylinder. And a piston rod of the pressing cylinder is connected with the movable swing rod.

The pinch roller is sleeved on the pinch roller shaft, and the pinch roller can freely rotate around the pinch roller shaft.

In the initial state, the pinch roller shaft and the pinch roller on the pinch roller shaft are lifted up under the driving of the pressing mechanism. The plank passes through the conveyer belt and carries to the below of support, starts hold-down mechanism, promotes the activity pendulum rod and wind the pivot and rotate downwards, makes the pinch roller shaft descend, and the pinch roller is pressed on the plank, reaches the effect that steadily compresses tightly the plank constantly in the course of working to guarantee the precision of plank processing, improve the quality of carpenter's product.

In the process of processing the wood board, the movable swing rod drives the pinch roller shaft to swing, so that the pinch roller on the pinch roller shaft is pressed on the wood board, the height of the pinch roller can be adjusted, and wood boards with different sizes can be rapidly and stably pressed, thereby reducing the vibration of the wood board, improving the processing precision and greatly improving the production efficiency.

Fig. 2 is a front view of the present invention of a hold down for a woodworking engraving machine.

In the figure: 1. the device comprises a support, 2. a conveying belt, 3. a rotating shaft, 4. a movable swing rod, 5. a pressure wheel shaft, 6. a pressure wheel, 7. a connecting rod, 8. a fixed frame, 9. a pressure cylinder, 10. a piston rod, 11. a roller raceway, 12. a bearing, 13. a bearing seat and 14. a roller.

Detailed Description

The device of the utility model is used for pressing the wood board of the woodwork carving machine, as shown in figure 1 and figure 2, the device comprises a bracket 1, a conveyer belt 2 is arranged at the lower part of the bracket 1, and a rotating shaft 3 is arranged on the bracket 1 through a bearing seat 13 (a bearing 12 is arranged in the bearing seat 13). Two ends of the rotating shaft 3 are respectively provided with a movable swing rod 4, and the movable swing rods 4 at two sides are connected through a connecting rod 7. The movable swing rod 4 is provided with a roller 14, the support 1 is hinged with a fixed frame 8 below the movable swing rod 4 through a rotating shaft, a roller raceway 11 is arranged in the fixed frame 8, and the roller 14 is positioned in the roller raceway 11 in the fixed frame 8. The rollers 14 on the movable swing rods 4 at two sides are connected with a pinch roller shaft 5 through a connecting piece, a pinch roller 6 is sleeved on the pinch roller shaft 5, and the pinch roller 6 can rotate freely. The support 1 is provided with a pressing cylinder 9, and a piston rod 10 of the pressing cylinder 9 is connected (hinged) with the movable swing rod 4.

When a workpiece needs to be machined, the piston rod 10 of the pressing cylinder 9 is retracted, so that the movable swing rods 4 are driven to be lifted upwards, the connecting rods 7 connected between the movable swing rods 4 on two sides are lifted simultaneously, the roller 14 slides in the roller raceway 11 of the fixed frame 8, and the roller 14 is connected with the pinch roller shaft 5 through the connecting piece, so that the pinch roller shaft 5 is driven to be lifted. The board is then placed on the conveyor belt 2 and moved to the lower end of the pinch roller 6. The structural design of the roller 14 in the roller track 11 of the holder 8 has the advantage that: on one hand, the friction resistance of the mechanism during working is greatly reduced through the rolling connection of the roller 14 in the roller raceway 11 of the fixed frame 8; on the other hand, the fixing frame 8 can change the corresponding angle according to the different thicknesses of the processed materials, has good flexibility, can ensure that the pinch roller shaft 5 compresses the processed wood constantly in the processing process, and achieves the purposes of ensuring the processing precision and improving the processing quality.

And starting the pressing cylinder 9 again to extend the piston rod 10 of the pressing cylinder to push the movable swing rod 4 to swing downwards, so that the roller 14 slides in the roller raceway 11 on the fixed frame 8, the roller 14 is connected with the pressing wheel shaft 5 through the connecting piece to press the pressing wheel shaft 5 downwards, and the pressing wheel 6 which is sleeved on the pressing wheel shaft 5 and can rotate freely is pressed on the wood board to fix the wood board.

In addition, when the device is used, the extension distance of the piston rod 10 can be changed by changing the stroke of the pressing air cylinder 9, and the angle of the fixing frame 8 can be changed according to different materials, so that the position of the roller connected with the pressing wheel shaft 5 in the pulley roller path arranged in the fixing frame 8 is changed to achieve the positioning of different wood board sizes. Different materials can be selected for use according to the actual working condition for the material of pinch roller 6.
