The buffer member 74 is a pneumatic buffer, and has a cylinder 741 and a piston rod 742, the end of the piston rod 742 is connected to the stop end 732, and the piston rod 742 keeps shrinking toward the inside of the cylinder 741. entry trend.

As shown in Figures 2 and 5, under normal conditions, the linkage rod 73 is restrained by the piston rod 742 of the buffer member 74, driving the axle 72 to slide along the guide groove 130, and keeping the pressure wheel member 71 The trend of moving toward the bearing surface 111, when the driving member 40 is started and the interlocking belt member 30 is driven to run, the operator will stack the timber 200 from the feeding side 140, and make the timber 200 be positioned between the pressure wheel member 71 and Between the material feeding device 400, the wheel shaft 72 can slide in the guide groove 130, and the buffer member 74 is used to provide the pressing wheel 71 to produce a resilient effect on the wood 200, so that the pressing wheel 71 is against the wood. 200 on the outside surface, and the timber 200 is pressed against the abutment surface 111 of the baffle 11, and under the effect of the operation of the interlocking belt 30, the timber 200 will be smoothly fed towards the second direction II, and the cutter 120 To achieve the purpose of sawing processing.

And as shown in FIG. 5 , the wheel shaft 72 is used to slide along the guide groove 130, the position of the pressing wheel 71 can be adjusted, and the buffering member 74 is used to provide the pressing wheel 71 to produce a rebound effect on the wood 200, which is suitable for Guide the timber 200 within a certain width range.

When the width of the wood material 200 to be processed changes greatly, first unscrew the locking handle 15, and adjust the displacement of the material feeding device 400 and the pressure wheel unit 500 along the first direction I, so that the tool 120 and the bearing surface 111. The distance between the pressure rollers 71 is changed, and when the locking handle 15 is tightened again, the material feeding device 400 is urged to be positioned.

When wanting to replace the interlocking belt 30, as shown in Figure 8, the operator pulls the operating handle 55, uses the connecting rod 56 to pull the second positioning plate 13 and utilizes the guiding effect of the guide rod 53, so that the second positioning plate 13 The second positioning plate 13 and the second runner 22 approach the third positioning plate 14, so that the wheelbase of the second runner 22 relative to the first runner 21 can be reduced, and the interlocking belt 30 can be easily replaced. . After the replacement is completed, the operating handle 55 is pulled back to the original state as shown in Figure 7, and the second positioning plate 13 and the second runner 22 are pushed outward by the release force of the spring 54, so that the interlocking belt 30 is Stretch positioning. And the inclination angle of the second runner 22 can also be adjusted by operating the adjusting bolt 63 .

Effect of the present utility model is summarized as follows again:

1. The material feeding device 400 is suspended above the table top 110 by using the slide rail unit 300 , so that the table top 110 will not be loaded as a whole, so that the table top 110 remains horizontal.

2. The material feeding device 400 has the function of supporting and feeding the wood material 200, and the pressure wheel part 71 of the pressure wheel unit 500 only presses against the outer surface of the wood material 200, so the material feeding device 400 will not be as the existing Woodworking opportunities are limited by other components and can process wider timbers.

As shown in Fig. 9 and Fig. 10, the woodworking machine of the second preferred embodiment of the present invention is similar to the first embodiment, and the difference lies in that the pressure roller unit 500' has a The pressure wheel 71', a wheel shaft 72' which is fixedly connected with the pressure wheel 71' and passes through the guide groove 130, and a linkage rod which is pivotally arranged at the bottom of the workbench 100 and connected with the wheel shaft 72' 73', a positioning frame 74' fixed at the bottom of the workbench 100, a buffer member 75' arranged at the bottom of the workbench 100 and connected between the positioning frame 74' and the linkage rod 73', and a A control member 76' connected to the linkage rod 73'. The linkage rod 73' has a pivot end 731' pivoted on the workbench 100, a stop end 732' opposite to the pivot end 731' and connected to the axle 72', and a protruding end 732'. On the side of the locking end 732' and corresponding to the connecting portion 733' of the positioning frame 74' and a support rod 734' pivotally connected between the positioning frame 74' and the connecting portion 733', the buffer member 75' is The compression spring is set on the outside of the support rod 734', and the two ends are supported by the positioning frame 74' and the connecting part 733', and the elastic force of the buffer part 75' keeps the pressure wheel part 71' constant towards the material feeding The tendency of the device 400 to move. The control member 76' is in the shape of a long rod, and has an inner end 761' connected to the trigger end 732' and a control end 762' extending outside the workbench 100.

When the operator pushes the wood between the pressure wheel 71' and the material feeding device 400, the wheel shaft 72' is used to slide in the guide groove 130, and the buffer 75' is used to provide the pressure wheel 71' to The wood produces a bouncing effect, and can be smoothly driven by the material delivery device 400 and pressed by the pressure wheel 71 ′, so as to achieve the purpose of material delivery.

The operator can also use the control end 762' of the control member 76' to move towards the outside opposite to the material feeding device 400, so as to move the wheel shaft 72' and make the pressure roller 71' relative to the bearing When the surface 111 is far away (at this time, the buffer member 75' is in a compressed state and contains a return elastic force), the wood will be smoothly placed between the material feeding device 400 and the pressure wheel member 71'. When the release of the control end 762 ′, the elastic force of the buffer member 75 ′ is used to push the pressing wheel member 71 ′ to press against the side of the wood 200 .

Therefore, by utilizing the overall structure of the second embodiment, the purpose and effect of smooth material feeding and sawing can also be achieved.
