[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0020] Please refer to Figure 1 As shown, the utility model is a fixed-length sawing machine, comprising a frame 1, a conveyor 2, a trigger 3 and a saw breaker 4; the conveyor 2 is arranged on the frame 1, the trigger end of the trigger 3 is slidably arranged on the frame 1, and the trigger end of the trigger 3 is located in front of the discharge end of the conveyor 2, the trigger 3 is respectively communicated with the conveyor 2 and the saw breaker 4, the tool of the saw breaker 4 is swingably arranged on the frame 1, and the tool of the saw breaker 4 is located between the trigger end of the trigger 3 and the discharge end of the conveyor 2.

[0021] Working principle: A trigger 3 is slidably arranged on the frame 1, so that the distance between the trigger 3 and the saw 4 can be adjusted according to the required length of the pipe. During the cutting process, the conveyor 2 transports the pipe until the pipe abuts against the trigger end of the trigger 3, so that the trigger 3 controls the conveyor 2 to stop transporting and the saw 4 cuts the pipe, thereby obtaining the pipe of the required length. When the pipe falls, the trigger 3 controls the saw 4 to reset, and the conveyor 2 transports again, so as to achieve efficient fixed-length cutting of the pipe.

[0022] Please refer to Figure 2 As shown, further, the trigger 3 includes a mounting plate 31, a stop plate 32 and a limit switch 33, a guide column 311 is arranged on the plate surface of the mounting plate 31, the stop plate 32 is slidably arranged on the guide column 311, the limit switch 33 is arranged on the plate surface of the mounting plate 31, and the trigger end of the limit switch 33 is against the stop plate 32, and the limit switch 33 is respectively communicated with the conveyor 2 and the saw breaker 4.

[0023] As can be seen from the above description, the conveyor 2 transports the pipe against the plate 32, so that the plate 32 slides on the guide column 311 until the plate 32 triggers the limit switch 33, so that the limit switch 33 controls the conveyor 2 to stop transporting and the saw breaker 4 cuts the pipe, thereby obtaining a pipe of the required length. When the pipe falls, the trigger end of the limit switch 33 resets itself and controls the saw breaker 4 to reset, and the conveyor 2 transports again, and this cycle is repeated to achieve efficient fixed-length cutting of the pipe.

[0024] Please refer to Figure 2 As shown, further, the trigger 3 also includes a spring 34, and two ends of the spring 34 are respectively connected to the mounting plate 31 and the abutment plate 32.

[0025] It can be known from the above description that the spring 34 can buffer the impact of the stop plate 32 on the limit switch 33, and the spring 34 can help the trigger end of the limit switch 33 to reset.

[0026] Please refer to Figure 1 As shown, further, a bracket 11 is provided on the frame 1 , and the bracket 11 is located between the trigger end of the trigger 3 and the tool of the saw 4 .

[0027] From the above description, it can be seen that before the pipe resists to the trigger end of the trigger 3, it will first pass through the bracket 11, and the bracket 11 supports the pipe to prevent the pipe from falling due to gravity before being completely cut during the process of cutting the pipe by the saw 4, resulting in an uneven cross-section of the pipe.

[0028] Please refer to Figure 1As shown, further, a discharge air gun 12 is provided on the frame 1 , and the discharge air gun 12 is located between the trigger end of the trigger 3 and the bracket 11 .

[0029] It can be seen from the above description that after the pipe is cut, the unloading air gun 12 can ensure that the pipe is blown off the bracket 11 to avoid the pipe not falling and affecting the subsequent transportation of the pipe.

[0030] Please refer to Figure 1 As shown, further, the conveyor 2 includes a motor 21, an output wheel 22 and a supporting wheel group 23; the output wheel 22 is drivingly connected to the output shaft of the motor 21, the supporting wheel group 23 is arranged on the frame 1, and a material passage space is formed between the supporting wheel group 23 and the output wheel 22.

[0031] As can be seen from the above description, the motor 21 drives the output wheel 22 to rotate so that the pipe can be moved on the supporting wheel set 23, thereby realizing the transportation of the pipe.

[0032] Please refer to Figure 1 As shown, further, the conveyor 2 also includes a linear reciprocating device 24, which is arranged on the frame 1, and has a movable end that moves along the vertical direction, and the body of the motor 21 is arranged on the movable end of the linear reciprocating device 24.

[0033] It can be seen from the above description that the distance between the output wheel 22 and the supporting wheel set 23 can be controlled by using the linear reciprocating device 24, so as to adapt to the transportation of pipes with various diameters.

[0036] Working principle: A trigger 3 is slidably arranged on the frame 1, so that the distance between the trigger 3 and the saw breaker 4 can be adjusted according to the required length of the pipe. During the cutting process, the motor 21 drives the output wheel 22 to rotate so that the pipe can move on the supporting wheel set 23 until the pipe passes through the abutment plate 32 to trigger the limit switch 33, and then the limit switch 33 controls the conveyor 2 to stop transporting, and the saw breaker 4 cuts the pipe, so as to obtain the pipe of the required length. When the pipe falls, the limit switch 33 relies on its internal elastic component and spring 34 to push the abutment plate 32 to reset, and controls the saw breaker 4 to reset, and the conveyor 2 resumes transport, and this cycle is repeated to achieve efficient fixed-length cutting of the pipe.
