A positioning plate 12 is fixedly provided on the receiving platform 5 on the side of the first receiving seat 8 away from the second receiving seat 9. A pushing plate 13 is fixedly provided on the side of the second receiving seat 9 away from the first receiving seat 8, and a pushing cylinder for pushing the second receiving seat 9 to slide is fixedly provided on the receiving platform 5;

[0030] A connecting frame 14 is fixedly provided on the frame 1, and a fixing assembly is provided on the connecting frame 14, and the fixing assembly includes a clamping seat 15 arranged above the first material receiving seat 8 and facing it, and the clamping seat 15 is lifted and lowered with the connecting frame 14, and a second groove is provided at the bottom of the clamping seat 15, so that the clamping seat 15 approaches or moves away from the second clamping seat 15 to clamp or release the pipe fitting;

[0031] A cutting assembly is also provided on the connecting frame 14, and the cutting assembly is located between the positioning plate 12 and the first material receiving seat 8, and the material receiving table 5 is fixedly provided with an inclined first slide 16 on the side of the first material receiving seat 8 facing the positioning plate 12, and a first material receiving box 17 is provided at the lower end of the first slide 16, and the material receiving table 5 is fixedly provided with an inclined second slide 18 on the side of the first material receiving seat 8 facing the pushing plate 13, and a second material receiving box 19 is provided at the lower end of the second slide 18, and the first material receiving box 17 and the second material receiving box 19 are relatively fixedly placed on the frame 1.

[0032] The driving mechanism includes a rotating rod 20 that rotates with the frame 1. One end of the rotating rod 20 is connected to a driving motor for driving it to rotate. Two cams 21 are symmetrically fixed on the rotating rod 20. A connecting plate 22 abuts against the top of the cam 21. The lower ends of the two pushing rods 6 are fixedly connected to the two ends of the connecting plate 22 respectively. A return spring 23 is fixedly abutted between the connecting plate 22 and the receiving platform 5.

[0033] A reducer (not shown) is arranged on the output shaft of the driving motor, and the output shaft of the reducer is in transmission connection with the rotating rod 20, thereby ensuring that the cam 21 slowly pushes the push rod 6, and preventing the push rod 6 from pushing the pipe too fast, causing the pipe to jump and thus unable to slide smoothly into the first groove;

[0034] The fixing assembly also includes a clamping cylinder fixed on the connecting frame 14, the telescopic end of the clamping cylinder is fixedly connected to the clamping seat 15, and the clamping seat 15 is symmetrically provided with positioning rods 24 on both sides of the clamping cylinder, and a through hole is opened on the connecting frame 14 for the positioning rod 24 to slide through, so that the clamping seat 15 remains stable during the lifting movement.

[0035] A slider 25 is symmetrically fixed at the bottom of the second material receiving seat 9. The slider 25 is a T-shaped structure. A slide groove 26 for the slider 25 to slide is opened on the material receiving platform 5. Through the cooperation of the slider 25 and the slide groove 26, the moving path of the slider 25 is limited to avoid the second material receiving seat 9 from being offset when driven by the pushing cylinder.

[0036] A rubber buffer layer is bonded to the inner wall of the second groove to increase the friction force when in contact with the pipe fitting and enhance the clamping effect.

[0037] The cutting assembly includes a support arm 27 rotatably cooperated with the connecting frame 14 and a swing motor fixed on the connecting frame 14 for driving the support arm 27 to swing. A cutting motor is fixedly provided at the other end of the support arm 27, a cutting blade 28 is fixedly provided on the cutting motor, and a protective cover is provided on the outer cover of the cutting blade 28.

[0038] Working principle: when in use, multiple pipe fittings to be cut are placed on the support plate 2 and blocked by the limit plate 4, so that the pipe fittings slide to the lower end of the slide and stay there, and the driving motor is started, and the driving motor drives the cam 21 to rotate. During the rotation, the protruding part of the cam 21 will push the connecting plate 22 to move upward, and the return spring 23 is continuously compressed, thereby driving the push rod 6 to push the pipe fitting upward, so that the pipe fitting passes over the limit plate 4 upward, and the first inclined surface 7 on the top of the push rod 6 is set, so that the pipe fitting can slide along the first inclined surface 7 to the second inclined surface 11 of the guide block 10, and then fall into the first grooves of the first material receiving seat 8 and the second material receiving seat 9. When the protruding part of the cam 21 rotates away from the position in contact with the connecting plate 22, the connecting plate 22 will drive the push rod 6 to move downward under the elastic recovery action of the return spring 23;

[0039] Subsequently, the push cylinder extends and pushes the other end of the pipe from one end of the pipe to contact the positioning plate 12 through the push plate 13, and the clamping cylinder pushes the clamping seat 15 downward, so that the inner wall of the second groove contacts the pipe, and the first groove and the second groove clamp and fix the pipe from both sides of the pipe respectively, and the swing motor rotates to drive the support arm 27 to swing, so that the high-speed rotating cutting blade 28 driven by the cutting motor approaches and cuts the pipe, and the cut pipe falls and slides along the first slide 16 into the first receiving box 17, and then the clamp The holding cylinder retracts and drives the clamping seat 15 upward to cancel the clamping of the pipe. The pushing cylinder continues to extend and pushes the pipe forward to resist the positioning plate 12, and then the fixed-length cutting is performed again. This cycle is repeated to achieve multiple fixed-length cuttings until the last section of the pipe is not enough to meet the preset cutting length. The pushing cylinder drives the second receiving seat 9 to move back, and the last section of the waste pipe loses the support of the second receiving seat 9, and will fall from the first receiving seat 8 to the second slide 18, and slide along the second slide 18 to the second receiving box 19.

[0040] The utility model drives the pushing rod 6 to push the pipe fitting upward to cross the limit plate 4 through the driving mechanism provided, and falls onto the first material receiving seat 8 and the second material receiving seat 9 through the connected first inclined surface 7 and the second inclined surface 11. The second material receiving seat 9 pushes the pipe fitting forward to contact the positioning plate 12 through the pushing plate 13, thereby realizing automatic feeding of the pipe fitting, avoiding the tedious and dangerous manual operation, and clamping the pipe fitting through the clamping seat 15 to facilitate cutting. The cut pipe fitting and waste are separately collected through the first slide 16 and the second slide 18, respectively, to reduce the subsequent workload.

[0041] The push cylinder, clamping cylinder, drive motor, swing motor and reducer of the utility model are all regulated and coordinated by being electrically connected to the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
