[0033] Specifically, Figure 1 and Figure 2As shown, one end of the cutting machine 201 is rotatably connected to the top side of one end of the mounting seat 1 through a connecting block 205, a pressure rod 203 at a 45-degree angle is fixedly connected to the top of the cutting machine 201, a column 202 is vertically fixedly connected to the top of one end of the mounting seat 1, a cylinder 204 is rotatably connected to the column 202, and the output shaft of the cylinder 204 is rotatably connected to one end of the pressure rod 203. Through the installation of the connecting block 205, one end of the cutting machine 201 can be rotatable with the mounting seat 1, and through the installation of the column 202, the cylinder 204 is connected to the mounting seat 1, and through the operation of the cylinder 204, the pressure rod 203 is driven and controlled, thereby realizing the swing control of the cutting machine 201, which is beneficial for the cutting machine 201 to cut pipes.

[0034] Specifically, Figure 2 and Figure 4 As shown, a through slot 206 is provided on the mounting seat 1, and both ends of the through slot 206 are arc-shaped structures. The bottom of the through slot 206 extends to the outside of the bottom of the mounting seat 1, and the through slot 206 is located at the bottom of one side of the cutting machine 201. Two parallel guide plates 207 are installed on the top of the mounting seat 1. The opening of the through slot 206 facilitates the cutting machine 201 to cut the pipe. The saw blade of the cutting machine 201 can extend into the through slot 206 to cut the pipe, thereby ensuring that the mounting seat 1 will not be damaged by cutting and allowing debris to fly downward.

[0035] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the conveying mechanism 3 includes a mounting frame 301, and the mounting frame 301 is installed on one side of the mounting seat 1. The cross-section of the mounting frame 301 is an "H"-shaped structure. A plurality of equally spaced electric rollers 302 are rotatably connected to the mounting frame 301. The installation of the mounting frame 301 facilitates the connection of the plurality of equally spaced electric rollers 302. The operation of the plurality of electric rollers 302 facilitates the conveying of the pipe to the bottom of the cutting machine 201 for cutting. The number of rotations of the electric rollers 302 can control the distance of the pipe push, thereby cutting the pipe of a specified length.

[0036] Specifically, Figure 3 and Figure 7As shown, the mounting frame 301 is fixed with multiple groups of equally spaced fixed blocks 303, two symmetrical fixed blocks 303 form a group, the two fixed blocks 303 are fixedly connected with fixed shafts 306, the fixed shafts 306 are rotatably connected with guide rods 304 through torsion springs 305, one end of the two guide rods 304 extends to the inside of the mounting frame 301, the guide rods 304 are rotatably connected to the side wall of the mounting frame 301, and the angle between the guide rods 304 and the side wall of the mounting frame 301 is 30 degrees One end of the guide rod 304 is rotatably connected to a guide wheel 307, which is installed through the symmetrical fixing block 303, which is conducive to the symmetrical rotation connection of the guide rod 304.

Through the installation of the guide wheel 307, the pipe can be guided smoothly without wear.

[0037] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the support mechanism 4 includes a connecting plate 407, and a plurality of connecting plates 407 are respectively installed at the bottom of the mounting frame 301 and the mounting seat 1, and the two ends of the bottom of the plurality of connecting plates 407 are respectively rotatably connected with symmetrical top plates 405, and the bottoms of the two top plates 405 are respectively slidably connected with support plates 401, and a cross plate 403 is provided between the two support plates 401, and the two ends of the cross plate 403 are slidably connected with slide plates 406, and one end of the two slide plates 406 is respectively rotatably connected to the side walls of the support plates 401, and a hydraulic cylinder 404 is vertically connected at the top center of the cross plate 403, and the top output shaft of the hydraulic cylinder 404 is connected to the bottom center of the connecting plate 407, and the installation of the connecting plate 407 is performed by , which is conducive to the rotational connection of the two top plates 405. Through the installation of the two support plates 401, with the cooperation of the cross plate 403 and the slide plate 406, the installation of the hydraulic cylinder 404 is realized. The support of the connecting plate 407 by the hydraulic cylinder 404 is conducive to the stable connection between the top plate 405 and the support plate 401, so that the support of the mounting frame 301 and the mounting seat 1 is stable. Through the synchronous control of the multiple hydraulic cylinders 404, the hydraulic cylinder 404 drives the connecting plate 407 to rise, and the top plate 405 slides with the top of the support plate 401, which is conducive to the height control of the mounting frame 301 and the mounting seat 1, and is convenient for the good feeding and transportation of pipes.

[0038] Specifically, Figure 2 , Figure 3 and Figure 5As shown, the bottom of the two support plates 401 are rotatably connected to support seats 402 respectively, and the bottom of the support seats 402 is a toothed structure. Through the rotational installation of the support seats 402, the bottom of the support plate 401 is always kept in close contact with the ground, which is beneficial to the stable support of the support plate 401. The design of the toothed structure increases the friction force and prevents the support from slipping.

[0039] Specifically, Figure 2 As shown, the dust collection mechanism 5 includes a collecting box 501. The collecting box 501 is installed at the bottom of the mounting base 1. The collecting box 501 is located at the bottom of the through slot 206. The collecting box 501 is a funnel-shaped structure. A dust collection tube 502 is vertically connected to one side of the bottom of the collecting box 501. The installation of the collecting box 501 facilitates the collection and storage of debris discharged from the through slot 206. The installation of the dust collection tube 502 and an external vacuum cleaner can realize the extraction of debris inside the collecting box 501 to reduce pollution.

[0040] Specifically, Figure 4 and Figure 6 As shown, the extrusion mechanism 6 includes a movable rod 602, and two groups of movable rods 602 are vertically connected to the mounting seat 1, and two of the movable rods 602 form a group. A pressure plate 601 is slidably connected to the two movable rods 602. The bottoms of both ends of the pressure plate 601 are slidably connected to the movable rod 602 through a reset spring 605. The tops of the two movable rods 602 are respectively threaded with nuts 603, and the nuts 603 are in conflict with the pressure plate 601. A gas spring 606 is vertically connected to the center of the top of the pressure plate 601. The output shaft of the top of the gas spring 606 is in conflict with the bottom of the cutting machine 201. The installation of the movable rod 602 is conducive to the pressure plate 6 01 sliding connection, in the absence of external force, the return spring 605 resists the pressure plate 601 to rise to a certain height, which is convenient for the pipe to pass through the bottom of the pressure plate 601, and the height adjustment and limit of the pressure plate 601 are achieved through the installation of the nut 603. When the cutting machine 201 presses down to cut, the cutting machine 201 resists the gas spring 606 in advance, and the gas spring 606 drives the pressure plate 601 to slide down, so as to squeeze and fix the pipe. At the same time, the gas spring 606 is retractable. After the pipe is squeezed into place, the cutting machine 201 can get rid of the pressure of the gas spring 606 and continue to slide to achieve cutting.

[0041] Specifically, Figure 6As shown, a rubber block 604 is installed at the bottom center of the pressure plate 601, and the rubber block 604 is a trapezoidal structure. A top block 607 is installed on the top of the gas spring 606. The top of the top block 607 is rotatably connected to a pressure wheel 608, and the pressure wheel 608 contacts the bottom side of the cutting machine 201. The installation of the rubber block 604 is conducive to the pressure plate 601 not being worn when squeezing the pipe, and plays an anti-skid role. The installation of the pressure wheel 608 enables the cutting machine 201 to smoothly drive and control the gas spring 606.

[0042] When the present invention is in use, firstly, the installation of the cutting machine 201 facilitates the cutting of the pipe. By installing the connecting block 205, one end of the cutting machine 201 can rotate with the mounting seat 1. By installing the column 202, the connection with the cylinder 204 is realized. By the operation of the cylinder 204, the driving control of the pressure rod 203 is realized, and then the swing control of the cutting machine 201 is realized, which facilitates the cutting machine 201 to cut the pipe. By opening the through slot 206, the saw blade of the cutting machine 201 can extend into the through slot 206 to cut the pipe, thereby ensuring that the mounting seat 1 will not be damaged by cutting and allowing the debris to fly downward. By installing the guide plate 207, it is beneficial to guide the pipe and prevent the pipe from being damaged. The material is offset during loading. The installation of the mounting frame 301 facilitates the connection of multiple equally spaced electric rollers 302. The operation of multiple electric rollers 302 facilitates the transportation of the pipe to the bottom of the cutting machine 201 for cutting. The number of rotations of the electric rollers 302 can control the distance of the pipe push, and then cut the pipe of a specified length. The symmetrical fixing blocks 303 are installed to facilitate the rotation connection of the symmetrical guide rods 304. With the cooperation of the torsion springs 305, the guide rods 304 are swung at a certain angle, which is conducive to the pipe being guided by the two guide rods 304 when being transported on the mounting frame 301, and the pipe is located at the center line of the mounting frame 301. The installation of the guide wheel 307 can achieve smooth pipe guidance without wear. The installation of the connecting plate 407, It is beneficial to the rotation connection of the two top plates 405. Through the installation of the two support plates 401, with the cooperation of the cross plate 403 and the slide plate 406, the hydraulic cylinder 404 is installed. Through the support of the connecting plate 407 by the hydraulic cylinder 404, the top plate 405 and the support plate 401 are stably connected, so that the mounting frame 301 and the mounting seat 1 are stably supported. Through the synchronous control of multiple hydraulic cylinders 404, the hydraulic cylinder 404 drives the connecting plate 407 to rise, and the top plate 405 and the top of the support plate 401 slide, which is beneficial to the height control of the mounting frame 301 and the mounting seat 1, and is convenient for the good feeding and conveying of the pipe. Through the rotation installation of the support seat 402, the bottom of the support plate 401 is always kept in close contact with the ground, which is beneficial to the support and stability of the support plate 401. The design of the toothed structure increases the friction force and prevents the support from slipping. The installation of the collection box 501 facilitates the collection and storage of the debris discharged from the through slot 206. The installation of the dust suction tube 502 and the external dust collector realizes the extraction of the debris inside the collection box 501 to reduce pollution. The installation of the movable rod 602 facilitates the sliding connection of the pressure plate 601. The pressure plate 601 rises to a certain height due to the resistance of the return spring 605 without external resistance, which facilitates the passage of the pipe at the bottom of the pressure plate 601. The installation of the nut 603 realizes the height adjustment and limit of the pressure plate 601. When the cutting machine 201 is pressed down and cut, the cutting machine 201 resists the gas spring 606 in advance, and the gas spring 606 drives the pressure plate 601 to slide down to squeeze and fix the pipe.At the same time, the gas spring 606 is retractable. After the pipe is squeezed into place, the cutter 201 can get rid of the pressure of the gas spring 606 and continue to slide to achieve cutting. The installation of the rubber block 604 is conducive to the pressure plate 601 not being worn when squeezing the pipe, and plays an anti-skid role. The installation of the pressure wheel 608 enables the cutter 201 to smoothly drive and control the gas spring 606.
