[0027] During use, the staff first places the PE tube on the feeding rack 18, ensuring that one end of the PE tube is aligned and contacts the starting position of the first table panel 2; according to the required cutting length, the operator adjusts the adjustable handle screw 14 on the sliding seat 13 to drive the sliding seat 13 to slide on the slide rail 10, thereby adjusting the position of the second material guide baffle 11, wherein the scale value on the inner side of the second material guide baffle 11 helps the operator to quickly and accurately set the required length; close the safety door 20 of the protective cover 19 to ensure safety during operation; when the PE tube is fed onto the first table panel 2, the positioning assembly 7 starts working, and the first positioning cylinder 702 pushes the first extrusion plate 703 close to the PE tube, pressing it tightly against the first limit plate 701 to achieve preliminary positioning; if more complex positioning is required, such as preventing the PE tube from rotating during cutting, the second limit plate 712 drives the second extrusion plate 714 to apply pressure to the PE tube through the dual-axis cylinder 713 to ensure that the PE tube is completely fixed; the first material guide baffle 6 and The second guide baffle 11 works together to guide the PE pipe along a predetermined path while limiting its movement in the vertical direction; the cutting assembly 5 is started, and the driving cylinder 502 pushes the cutting motor 506 connected to the "Y"-shaped joint 505 to move forward until the saw blade 507 contacts the PE pipe; the cutting motor 506 starts to rotate, and the saw blade 507 cuts the PE pipe. The hydraulic buffer 508 plays a role in stabilizing the support arm 504 during this process, reducing vibration during cutting and improving cutting accuracy; after the cutting is completed, the cutting assembly 5 returns to its original position and waits for the next cutting; when the PE pipe is cut to the required length, the jacking assembly 9 is started, and the jacking cylinder 903 drives the lifting plate 902 to descend, thereby driving the cut PE pipe to move downward synchronously, and then the unloading cylinder 17 works, and the unloading cylinder 17 drives the unloading push plate to push the PE pipe on the lifting plate 902 into the storage box 16 to complete the unloading process; if continuous cutting is required, the operator can repeat the above steps until all required cutting tasks are completed.

[0028] Please refer to Figure 3 、 Figure 5As an embodiment of the present invention, the cutting assembly 5 includes a cylinder bracket 501, wherein the lower end of the cylinder bracket 501 is connected to the fixed frame 4; a driving cylinder 502 is provided at the upper end of the cylinder bracket 501, wherein the cylinder end of the driving cylinder 502 is provided with a double-ear base 503, and the double-ear base 503 is movably connected to the cylinder bracket 501 through a rotating shaft; a support arm 504 is provided in the middle section of the cylinder bracket 501, wherein the support arm 504 is rotatably connected to the cylinder bracket 501 through a rotating shaft; a "Y"-shaped joint 505 is provided at the top end of the piston rod of the driving cylinder 502, wherein the support arm 504 is movably connected to the "Y"-shaped joint 505 at one end away from the cylinder bracket 501 through a movable pin; a cutting motor 506 is fixedly installed at the front end of the support arm 504, wherein a saw blade 507 is installed on the output shaft of the cutting motor 506, and the saw blade 507 is arranged above the positioning assembly 7.

[0029] In the above-mentioned scheme, the cutting assembly 5 is firmly connected to the fixing frame 4 through the cylinder bracket 501, ensuring the stability and safety of the entire assembly during operation; the driving cylinder 502 is in an inactive state, and its piston rod is in a retracted position, so that the "Y"-shaped joint 505 and the support arm 504 remain in a relatively fixed initial position; the cutting motor 506 is not started, and the saw blade 507 is in a stationary state; when the cutting task needs to be performed, the driving cylinder 502 receives a start signal and starts working; the piston rod of the driving cylinder 502 gradually extends, pushing the "Y"-shaped joint 505 forward, and since the "Y"-shaped joint 505 is connected to the support arm 504 through a movable pin, this push is converted into a rotational motion of the support arm 504; the support arm 504 rotates around its axis on the cylinder bracket 501, and at the same time drives the cutting motor 5 06 and the saw blade 507 move forward together until the saw blade 507 reaches a predetermined cutting position; when the saw blade 507 contacts the PE pipe to be cut, the cutting motor 506 starts, and its output shaft drives the saw blade 507 to rotate at high speed; the saw blade 507 cuts the PE pipe with its sharp cutting edge, and due to the high-speed rotation and appropriate pressure of the saw blade 507, the PE pipe is cut quickly and accurately; after the cutting is completed, the driving cylinder 502 receives a stop signal, wherein the driving cylinder 502 controls the piston rod to start contracting; as the piston rod contracts, the "Y"-shaped joint 505 moves backward, driving the support arm 504 to rotate in the opposite direction around its rotating axis through the movable pin; the support arm 504 and the cutting motor 506 return to the initial position together, and the saw blade 507 leaves the cut PE pipe; the cutting motor 506 stops working and the saw blade 507 stops rotating.

[0030] See also Figure 5 As an embodiment of the present invention, a hydraulic buffer 508 is provided under the support arm 504 , wherein the movable end of the hydraulic buffer 508 is connected to the support arm 504 , and the fixed end of the hydraulic buffer 508 is fixedly connected to the cylinder bracket 501 .

[0031] In the above-described scheme, the hydraulic buffer 508 is installed under the support arm 504, with its fixed end firmly connected to the cylinder bracket 501, and the movable end is connected to the support arm 504; before the cutting assembly 5 starts working, the hydraulic buffer 508 is in standby mode; when the driving cylinder 502 pushes the support arm 504 and the cutting motor 506 forward to prepare for cutting, the hydraulic buffer 508 begins to play its role; as the support arm 504 rotates and moves, the movable end (i.e., the piston) gradually compresses the space in the buffer under the action of hydraulic oil; this compression process will generate a certain resistance, which helps to slow down the movement speed of the support arm 504, thereby avoiding excessive impact force when the cutting motor 506 and the saw blade 507 contact the PE pipe; after the cutting is completed, the piston rod of the driving cylinder 502 begins to shrink, driving the support arm 504 and the cutting motor 506 to move backward. During this process, the movable end of the hydraulic buffer 508 begins to move in the opposite direction, gradually releasing the previously compressed hydraulic oil; the release process of the hydraulic oil will also generate a certain resistance, which helps to smoothly slow down the reset speed of the support arm 504 and prevent vibration or impact caused by rapid reset; by installing the hydraulic buffer 508 under the support arm 504, the cutting assembly 5 can maintain a more stable motion trajectory during the cutting process, which helps to reduce the vibration and noise generated by cutting and improve the accuracy and efficiency of cutting; at the same time, the presence of the hydraulic buffer 508 also increases the safety performance of the cutting assembly 5 and reduces the risk of accidents caused by improper operation or equipment failure.

[0034] When the PE pipe to be positioned is fed into the positioning assembly 7, it is first preliminarily guided by the first material guide baffle and the second material guide baffle 11 to ensure that the workpiece moves in the correct direction; when the PE pipe reaches the predetermined position, the first positioning cylinder 702 receives a start signal and drives the piston rod to begin to extend. As the piston rod of the first positioning cylinder 702 extends, the first extrusion plate 703 gradually approaches the first limit plate 701 and squeezes and positions the PE pipe; since the first extrusion plate 703 corresponds to the first limit plate 701, they together form a clamping space to firmly position the PE pipe at the specified position; while the first extrusion plate 703 moves, the connecting plate 707 also moves accordingly, and since the lower end of the connecting plate 707 is fixedly connected to the first slider 706, the first slider 706 is on the first guide rail 705 slides on to ensure the smooth movement of the connecting plate 707 and the first extrusion plate 703; when the first extrusion plate 703 reaches the predetermined position and clamps the PE pipe together with the first limit plate 701, the first positioning cylinder 702 keeps the piston rod in the extended state, thereby keeping the PE pipe in the positioned state; at this time, the PE pipe is stably positioned in the positioning assembly 7, providing an accurate reference for subsequent cutting or processing operations; when the PE pipe is processed, the first positioning cylinder 702 controls the piston rod to start contracting, and as the piston rod contracts, the first extrusion plate 703 gradually moves away from the first limit plate 701; at the same time, the first extrusion plate 703, the connecting plate 707 and the first slider 706 are reset to the initial state under the action of the piston rod contraction of the first positioning cylinder 702, waiting for the start of the next positioning task.
