Thereby, when the conveying device 13 carries the wood material and passes through the cutting device 12 in a straight direction, the cutting device 12 which can move up and down can cut the wood material to form the wood material into a plurality of boards. However, although the aforementioned frame saw machine 1 can achieve the purpose of sawing wood, it still needs to be solved urgently in actual use: Since the cutting device 12 and the conveying device 13 are driven by the same power source, they move synchronously Therefore, when the cutting device 12 moves downwards to cut the sawn wood, and when the upward displacement 15 returns to the original position, the conveying device 13 keeps the state of movement continuously, so that the wood continues to travel, so whenever the cutting device 12 completes The sawing action, and in the process of returning to the original position, the wood will travel a further distance forward. At this time, as compared with the cutting device 12, it is easy for the cutting deviation to occur, so that the cutting device 12 It is not that the wood is continuously sawn from the original position of the incision 20, but the lack of flat cuts on the board is missing. [New content] Therefore, the object of the present invention is to provide a frame IS machine feeding device capable of intermittently traveling wood. Therefore, the frame saw has a cutting device that can cut wood. The feeding device includes a conveying unit, a transmission unit, a driven unit, and a shaft connection unit. The conveying unit is capable of carrying wood and passing through the cutting device, and has a plurality of rollers arranged along the conveying track and interconnected. The transmission unit has a motor, two coaxial cams 5 located on one side and the other side of the frame mining machine, and two connecting rods respectively connecting the two sides of the cutting device and the eccentric position of the cam. The cam can be driven by the motor When the cam rotates, the connecting rod drives the cutting device to move up and down. The driven unit has two driven shafts which are respectively pivoted on one side and the other side of the frame saw, and two driven wheels which are respectively fixedly connected to the driven shaft. One of the driven wheels can be driven by one of the cams. The other driven wheel is a roller that can be linked at the extreme end. The shaft connection unit has two universal joints which are respectively consolidated with the driven shaft, and a universal post connecting the two universal joints, so that the two driven shafts are linked, and the universal joints each have a U-shaped seat. The universal post extends at an inclined angle in the horizontal direction, and has a U-shaped head formed at the two ends and pivotally connected to the universal joint u-shaped seat. The U-shaped seat and the U-shaped head may be 15 opposite to each other at least An angle greater than 180 degrees rotates in the horizontal and vertical directions, and cooperates with the inclination angle of the universal joint, so that the U-shaped seat and the U-shaped head will interfere with each other and transmit only at a specific intersection angle, resulting in 20,000 Asynchronous rotation to the joint allows the conveying unit to have a dwell time relative to the cutting device. 20 The effect of this new model is to keep the cut of wood cut flat. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the accompanying drawings. 6 M245040 Referring to FIG. 2, FIG. 3 and FIG. 4, the frame saw 2 has a machine 21 and a cutting device 22 located at the center of the machine 21 and capable of moving up and down. The preferred embodiment of the novel feeding device is installed on the machine table 21 of the frame saw 2 and includes a conveying unit 3, a transmission unit 4, a driven unit 5 5 and a shaft connection unit 6 (as shown in Fig. 6). Show). The conveying unit 3 has a plurality of rollers 31 arranged along the longitudinal direction of the machine table 21, a plurality of gears 32 fixed on the end side of the rollers 31, and a plurality of chains 33 connecting the adjacent rollers 31 and their gears 32. The rollers 31 are linked to each other, and the wood can be carried along the length direction of the machine table 21. 10 The transmission unit 4 has a motor 41, two coaxial cams 42 and 43, located on the side 21 and the other side 212 of the machine 21, and two cams 42 and 43 connecting the cutting device 22 to the eccentric positions of the cams 42 and 43 respectively. A lever 44, a pinion 45 and a belt 46 that rotate in synchronization with the cam 42. The motor 41 is disposed at a position adjacent to one end 213 of the machine table 21 and has a pulley 411 15. The belt 43 is a sleeve 41 and a cam 42. The motor 41 can drive the cams 42 and 43. The linkage between the cutting device 22 and the cutting device 22 through the link 44 can drive the cutting device 22 to move up and down. The driven unit 5 has two driven shafts 51, 52, which are pivoted on the machine 21-side 211 and the other side 212, respectively, and two driven wheels 53, 54 and 2 which are fixedly connected to the driven shafts 51, 52, respectively. The chains 55 and 56 and a first toothed plate 57 and a second toothed plate 58 disposed on the machine table 21 and adjacent to the other end 214 of the machine table 21. The chain 55 is connected to the driven wheel 53 and the pinion 45 to link the cam 52 with the driven shaft 51. The chain 56 is connected to the second toothed plate 58 and the roller 31 adjacent to the other end 214 of the machine 21 Gear 32 7 M245040. The first toothed plate 57 is meshed with the driven wheel 54 to make the conveying unit 3 and the driven shaft 52 interlock with each other through the above-mentioned transmission relationship, and can improve the smoothness and stability during transmission. Referring to FIG. 5, FIG. 6 and FIG. 7, the shaft connection unit 6 has two universal joints 61 which are respectively fixed to the moving shafts 51 and 52, and a universal joint 62 connected to the two universal joints 61, so that The two driven shafts 51 and 52 are linked. The universal joints 61 each have a U-shaped seat 611. The universal post 62 extends in a horizontal direction at an inclination angle of 45 degrees, and has a U-shaped head 621 formed at both ends and pivotally connected to the universal joint 61 U-shaped seat 611. The U-shaped seat 611 and the U 10-shaped head 621 can be rotated horizontally and vertically at an angle of at least greater than 180 degrees. According to the inclination angle of the universal joint 62 described above, the U-shaped seat 611 and the U-shaped seat The head 621 only intersects with each other when it intersects at 45 degrees. Based on the above U-shaped seat 611 and the U-shaped head 621 only transmits when it intersects at 45 degrees and 15 degrees. Therefore, when the U-shaped seat 611 rotates, When it is less than 45 degrees, the U-shaped head 621 will not be driven. When the U-shaped seat 611 rotates to more than 45 degrees, it will start to drive the U-shaped seat 611 to rotate, and when the U-shaped seat 611 and the U-shaped head 621 rotate to When it intersects vertically, the above-mentioned angular action is repeated again, and so on. When the U-shaped seat 611 rotates to 90 degrees, the U-shaped head 621 rotates to 45 degrees, and when the U-shaped seat 611 rotates to 135 degrees. The U-shaped head 621 will not be driven. When the U-shaped seat 611 is rotated to 180 degrees, the U-shaped head 621 will be rotated to 90 degrees. When the U-shaped seat 611 is rotated to 235 degrees, the U-shaped head 621 will be driven. It will not be driven. When the U-shaped seat 611 rotates to 280 degrees, the U-shaped head 621 will rotate to 135 degrees, and when the 8 U-shaped seat 611 rotates to 335 degrees, the U-shaped head 621 will not be driven, when the U-shaped seat 611 _ to 360 degrees, the U-shaped head 621 will rotate to 180 degrees "causing the two universal joints 61 * synchronous rotation, that is, when the motor 4W moving cam 42 rotates One turn (36 °), so that the cutting device 22 completes the upward ore cutting and upward return to the original position. The driven wheel M can only be rotated 180 degrees so that the shipping note 疋 3 can be returned to the original position relative to the cutting dress. Bit, it has a dwell time. With this 'Re-reference 2, 2, 3, 4, when the motor 41 drives the cam I' 43i and drives the cutting device 22 up and down through the connecting rod 44, the driven unit 5 will pass the shaft connection unit 6 to The power is transmitted to the conveying unit 3. Since the conveying unit 3 can return to the original position with respect to the cutting device 22, it has a dwell time to stop the wood from traveling. Therefore, only when the cutting device 22 plows the wood downward, it will carry the wood to travel and make the cutting Each sawing operation of the cutting dress 22 can be performed at the same cutting position. According to the above, it can be known that the feeding device of the new frame sawing machine has advantages and effects: Lu * Because the new model can make the conveying unit 3 up to the original position relative to the cutting device 22, it has -pause time, so that Every time the cutting operation of the cutting device i 22 can be performed at the relative position. In this way, the flatness of the material cut can be maintained, and the product quality and economic benefits can be effectively improved. The ones mentioned in quasi-X are only the preferred embodiments of the present invention.
