Then, the pushing assembly 3 is started again to push the workpiece. At the same time, the cut workpiece follows forward and falls onto the discharge assembly 7 for discharge. The pushing assembly 3 pushes the workpiece again to contact with the limit assembly 8 and then the cutting operation can be performed again. This cycle is repeated. While the workpiece is being cut, a new workpiece is placed on the rear side of the pushing assembly 3 and follows forward. When the front workpiece is completely cut off, the pushing assembly 3 is lifted up by the lifting assembly 4 and then returns to the initial position to push the subsequently placed workpiece.

While pushing the front workpiece, the new workpiece is placed in the discharge trough 15 and moves with the pushing block 16. When the push block 16 is completely separated from the discharge trough 15, the linear motor module 10 is started to send it back to the initial position, and then the micro-cylinder 18 is started to contract to make the push block 16 re-embedded in the discharge trough 15, waiting for the next pushing work. The jacking assembly 4 can be provided to move the parts on it upward by starting the micro-cylinder 18 after completing one push to avoid the workpiece on the rear side, so as to prevent it from touching the workpiece on the rear side during the process of returning to the initial position, and then the workpiece can be pushed continuously, thereby further increasing its work efficiency.

[0028] In order to facilitate the cutting operation of multiple workpieces at the same time, the cutting assembly 5 includes a U-shaped plate 25 fixedly connected to one end of the upper surface of the processing table 2 by bolts, and the upper surface of the U-shaped plate 25 is fixedly connected to a telescopic cylinder 26 by bolts, and the output end of the telescopic cylinder 26 passes through the top inner wall of the U-shaped plate 25 and is fixedly connected to a cross plate 27 by bolts, and the lower surface of the cross plate 27 is fixedly connected to the same number of cutters 28 as the push block 16 by bolts, and two symmetrical pressing assemblies 31 are provided on both sides of the cross plate 27, and limiting openings 29 are provided on both sides of the U-shaped plate 25. There are I-shaped blocks 30 slidably connected in the two limiting openings 29, and the opposite sides of the two I-shaped blocks 30 are fixed to the two ends of the cross plate 27 by screws. Bolts are fixedly connected to multiple mounting brackets 32 on both sides of the horizontal plate 27. The lower surface of the mounting bracket 32 ​​is fixedly connected with the same number of connecting blocks 33 as a group of push blocks 16 by bolts. The lower surfaces of the multiple connecting blocks 33 are bonded with inverted concave rubber blocks 34. When it is necessary to cut the workpiece, the telescopic cylinder 26 is started to extend rapidly. During the rapid extension of the telescopic cylinder 26, the horizontal plate 27 at its bottom will drop rapidly. When the cutter 28 at its bottom contacts the workpiece, it can be cut. Through the provided cutting assembly 5, multiple workpieces can be cut at the same time at one time. There is no need to cut them one by one, which reduces the time of the cutting operation and greatly increases the efficiency of cutting the workpiece.

[0029] In order to facilitate the fixed-length cutting of the workpiece, the limit assembly 8 includes a avoidance groove 41 opened on one side of the processing table 2, and the bottom inner wall of the avoidance groove 41 is fixedly connected with two symmetrical square tubes 35 by bolts, and the two square tubes 35 are slidably connected with a slide 36, and a threaded rod 39 is passed through the slide 36 and is threadedly connected to the slide 36. One end of the threaded rod 39 is rotatably connected to the baffle 40 through a bearing, and an electric push rod 37 is fixedly connected between the bottom inner wall of the avoidance groove 41 and the top inner wall of the slide 36 by bolts. One side of the baffle 40 is fixedly connected with two symmetrical scale rods 38 by bolts, and one end of the two scale rods 38 passes through the slide 36 and is slidably connected thereto. Before the cutting operation, the scale rods 38 are rotated with the slide 36. 6 threaded connection, since the threaded rod 39 is threadedly connected to the slide 36, the threaded rod 39 will move left and right when it is rotated, thereby driving the baffle 40 at one end of the threaded rod 39 to move left and right, thereby adjusting the distance between the baffle 40 and the cutter 28 so that the distance between them is the same as the length required to be cut. After the cutting is completed, the electric push rod 37 is started to extend, thereby causing the slide 36 and the baffle 40 to move upward, and continuing to push the workpiece can avoid the cut workpiece. The distance between the baffle 40 and the cutter 28 can be adjusted by the provided limit assembly 8, thereby changing the cutting length of the workpiece, and then the workpiece can be cut into different lengths according to needs, without manual measurement, simple structure and convenient operation.

[0030] In order to transport the workpiece after cutting, the discharge assembly 7 includes a conveyor belt 6 fixedly connected to one side of the avoidance groove 41 by bolts and located between the cutting assembly 5 and the limiting assembly 8. Rubber rings 42 are bonded to both ends of the conveyor belt surface of the conveyor belt 6. Through the provided discharge assembly 7, the workpiece is further pushed after being cut, so that the cut workpiece is pushed onto the conveyor belt 6 for convenient transportation of the cut workpiece, and the provided rubber ring 42 can prevent the workpiece from falling from both sides of the conveyor belt 6.

[0031] The present invention is divided into the following steps when used: S1: Before the cutting operation, the threaded rod 39 threadedly connected to the slide 36 is rotated. Since the threaded rod 39 is threadedly connected to the slide 36, the threaded rod 39 moves left and right when rotated, thereby driving the baffle 40 at one end of the threaded rod 39 to move left and right, thereby adjusting the distance between the baffle 40 and the cutter 28 so that the distance between them is the same as the length to be cut; S2: The workpieces to be cut are then placed into the plurality of discharge troughs 15 in sequence, with one end of the workpiece in contact with one side of the push block 16. The linear motor module 10 is started to drive the slide 13 thereon and the mounting plates 14 fixed on both sides of the slide 13 to move. During the movement of the mounting plates 14, the plurality of push blocks 16 below the workpieces move along the discharge trough 15, thereby pushing the workpieces. S3: When the workpiece needs to be cut, the telescopic cylinder 26 is activated to extend rapidly. During the rapid extension of the telescopic cylinder 26, the horizontal plate 27 at the bottom thereof is rapidly lowered. When the cutter 28 at the bottom thereof contacts the workpiece, the workpiece can be cut. S4: After completing a cutting operation, the electric push rod 37 is started to extend, thereby moving the slide 36 and the baffle 40 upward, and continuing to push the workpiece to avoid the cut workpiece. After the workpiece falls, the electric push rod 37 is started to retract, and the baffle 40 returns to the initial position; S5: While pushing the front workpiece, place a new workpiece into the discharge trough 15 and push it as the push block 16 moves, so that one end of the rear workpiece is always in contact with the other side of the push block 16; S6: After the workpiece on the front side is completely cut off, the micro cylinder 18 is started to extend. Since the micro cylinder 18 is fixed in the avoidance opening 17 on the slide 13, the slide 13 and the mounting plates 14 on both sides thereof are driven to move upward along the slide rod 12 while the micro cylinder 18 extends. When the push block 16 is completely separated from the discharge trough 15, it is sent back to the initial position by starting the linear motor module 10, and then the micro cylinder 18 is started to contract so that the push block 16 is re-embedded in the discharge trough 15.
