For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0050] A drainage pipe cutting device includes an operating table 1, a conveying wheel 2, a fixed length measuring device 4, an electric cutting machine 5 and a water pipe conveying frame 6;

[0051] The electric cutter 5, the conveying wheel 2, and the fixed-length measuring device 4 are sequentially mounted on the top surface of the operating table 1 from front to back, with the water pipe conveying rack 6 being mounted near the front of the operating table 1. The outer circumference of the conveying wheel 2 is provided with a drain pipe guide groove 21. The electric cutter 5 includes a drain pipe holder 52 and a rotary cutter 54. The drain pipe holder 52 passes through the electric cutter 5 from front to back, and the rotary cutter 54 is mounted inside the electric cutter 5. The drain pipe holder 52 is provided with a clamping groove 521, which passes through the drain pipe holder 52 from front to back.

[0052] The fixed length measuring device 4 is mounted between the electric cutting machine 5 and the conveying wheel 2. The fixed length measuring device 4 includes a measuring wheel 43 and an encoder 44. The measuring wheel 43 is located directly above the conveying wheel 2. The measuring end of the encoder 44 is connected to the measuring wheel 43. The encoder 44 is connected to the electric cutting machine 5 for signal transmission.

[0053] A conveying line 61 and a discharge assembly 62 are installed on the top of the water pipe conveying rack 6. The conveying line 61 is provided with a conveying trough 6121, and the conveying trough 6121 extends in the front-to-back direction. The discharge assembly 62 includes a plurality of rotatable flip arms 621, and the flip arms 621 are provided with supporting grooves 6211.

[0054] The flip arm 621 is provided with a feeding station and a unloading station; when located at the feeding station, the flip arm 621 is close to the conveying trough 6121, the bottom surface of the supporting trough 6211 faces upward, and the clamping groove 521, the conveying trough 6121 and the bottom surface of the drainage pipe guide groove 21 located at the top of the conveying wheel 2 are flush; when located at the unloading station, the flip arm 621 flips over and moves away from the conveying trough 6121, the bottom surface of the supporting trough 6211 faces downward, and is located on the outside of the water pipe conveying rack 6.

[0055] like Figure 1-5 As shown, the operating steps of using the drain pipe cutting device of the utility model are as follows:

[0056] S1) The front end of the drain pipe 10 extruded by the extruder is inserted into the drain pipe guide groove 21 on the top of the conveying wheel 2. Under the action of the output thrust of the extruder, the front end of the drain pipe 10 continuously moves forward;

[0057] S2) When the front end of the drain pipe 10 extends into the clamping groove 521 of the drain pipe clamp 52, the measuring wheel 43 of the fixed length measuring device 4 is placed directly above the drain pipe guide groove 21, and the bottom surface of the measuring wheel 43 rubs against the top surface of the drain pipe 10. The forward movement of the drain pipe 10 drives the measuring wheel 43 to rotate. The encoder 44 follows the rotation of the measuring wheel 43 and calculates the circumferential displacement of the measuring wheel 43, which is equal to the distance the front end of the drain pipe 10 has moved forward from the clamping groove 521.

[0058] S3) The front end of the drain pipe 10 continues to move forward and enters the conveying trough 6121. When the circumferential displacement of the measuring wheel 43 measured by the encoder 44 reaches the set threshold, the electric cutter 5 is activated, the rotary cutter 54 rotates and cuts the drain pipe 10. At the same time, the unloading assembly 62 is activated, and the flip arm 621 rotates from the feeding station to the unloading station, flipping the cut drain pipe 10 and unloading it to the drain pipe conveying line next to the water pipe conveying rack 6;

[0059] S4) Repeat step S3 until the extruded drain pipe 10 is completely cut.

[0060] The cutting speed of the drainage pipe cutting device of the utility model is higher than that of manual cutting, and the phenomenon of inconsistent cutting length will not occur.

[0061] Furthermore, it also includes a bracket 3;

[0062] The bracket 3 is mounted behind the conveying wheel 2;

[0063] The bracket 3 includes a support plate 31 and two limiting rods 32;

[0064] The supporting plate 31 extends in a direction perpendicular to the running direction of the drain pipe 10, and the top surface of the supporting plate 31 is flush with the bottom surface of the drain pipe guide groove 21 located on the top of the conveying wheel 2; the two limiting rods 32 are arranged upright, and the lower ends of the limiting rods 32 are connected to the top surface of the supporting plate 31, and the opposite surfaces of the two limiting rods 32 are used to abut against the two sides of the drain pipe 10 respectively.

[0065] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the drain pipe 10 input to the conveying wheel 2 is supported by the bracket 3, and the two sides of the drain pipe 10 are limited by two limit rods 32, which can reduce the left and right movement of the drain pipe 10 and the load applied by the drain pipe 10 to the conveying wheel 2, and can reduce the accuracy of the measurement data of the measuring wheel 43 affected by the deformation of the drain pipe 10.

[0066] Furthermore, it also includes a support frame 7;

[0067] The support frame 7 is installed between the drain pipe clamp 52 and the conveying line 61. The support frame 7 is provided with a first groove 71 extending in the front-to-back direction. The front end of the first groove 71 is close to and aligned with the rear end of the conveying groove 6121, and the rear end of the first groove 71 is close to and aligned with the front end of the clamping groove 521.

[0068] like Figure 1 and Figure 2 As shown, the support of the drain pipe 10 by the first groove 71 can ensure that the front end of the drain pipe 10 is aligned with the conveying trough 6121, and can also prevent the rear end of the cut drain pipe 10 from falling, thereby avoiding affecting the effectiveness of the unloading operation of the flip assembly 6.

[0069] Furthermore, the conveyor line 61 further includes a roller drive motor 613 and a plurality of rotatable rollers 611;

[0070] The plurality of rollers 611 are arranged in the conveying trough 6121 at intervals along the front-to-back direction. The outer circumference of the roller 611 is provided with a second groove. The bottom surface of the second groove located at the top of the roller 611 is flush with the bottom surface of the conveying trough 6121.

[0071] The roller driving motor 613 drives the multiple rollers 611 to rotate synchronously through multiple belts.

[0072] like Figure 1 and Figure 2 As shown, the roller drive motor 613 can drive the drain pipe 10 entering the conveying groove 6121 to move forward through the multiple rollers 611. When the drain pipe 10 is cut off, the rear end of the cut drain pipe 10 can leave the clamping groove 521 in time, which can prevent the cut drain pipe 10 from blocking the conveying of subsequent drain pipes 10 and avoid affecting the accuracy of the data detected by the measuring wheel 43.

[0073] Furthermore, the conveying line 61 further includes a plurality of covering covers 612;

[0074] The plurality of covering covers 612 are arranged at intervals along the front-to-back direction. The side of the covering cover 612 away from the roller 611 is fixed to the top surface of the water pipe conveying rack 6. The other side of the covering cover 612 close to the roller 611 extends obliquely upward. The side edge of the other side of the covering cover 612 is bent into a V-shaped conveying groove 6121 with the notch facing upward.

[0075] A cover 612 is disposed between two adjacent rollers 611 .

[0076] like Figure 1-3 As shown, the gap between two adjacent rollers 611 is covered by a covering cover 612 .

[0077] Furthermore, the unloading assembly 62 further includes a height limiting rod 622, a rotating shaft 623, a rotating shaft driving motor 625, a height limiting rod fixing bracket 624 and two rotating shaft fixing brackets 626;

[0078] The two rotating shaft fixing brackets 626 are respectively installed near the front end and the rear end of the water pipe conveying bracket 6;

[0079] The two ends of the rotating shaft 623 are rotatably inserted into the two rotating shaft fixing brackets 626; the plurality of flip arms 621 are sleeved on the outer circumference of the rotating shaft 623; the rotating shaft 623 extends in the front-to-back direction and is located below the cover 612; the rotating shaft drive motor 625 and the height-limiting rod fixing bracket 624 are respectively installed near one of the rotating shaft fixing brackets 626;

[0080] The output end of the rotating shaft driving motor 625 is in driving engagement with the outer circumference of the rotating shaft 623;

[0081] The height limiting rod fixing frame 624 is arranged upright, and the height limiting rod 622 extends horizontally in the front and rear directions. The height limiting rod 622 is inserted into the top of the height limiting rod fixing frame 624, and the bottom surface of the front end or rear end of the height limiting rod 622 is used to offset the top surface of the other end of the adjacent flip arm 621 away from the supporting groove 6211.

[0082] like Figure 1-3 As shown, the rotating shaft driving motor 625 drives the rotating shaft 623 and multiple flip arms 621 to flip synchronously, so as to realize the unloading of the drainage pipe 10 in the supporting groove 6211; after the unloading is completed, the rotating shaft driving motor 625 switches the rotation direction, so that the rotating shaft 623 and multiple flip arms 621 rotate in the opposite direction synchronously and reset, and the height of the other end of the flip arm 621 is limited by the blocking of the height limiting rod 622 to ensure that the bottom surface of the supporting groove 6211 on the flip arm 621 after reset is flush with the bottom surface of the conveying groove 6121, thereby ensuring the effectiveness of the subsequent unloading operation of the flip arm 621.

[0083] Furthermore, the fixed length measuring device 4 further includes a rotating rod 42, a rotating rod fixing frame 41 and a connecting plate 45;

[0084] The rotating rod fixing frame 41 is vertically mounted on the top surface of the operating table 1 and is located between the drain pipe holder 52 and the conveying wheel 2. The rotating rod 42 extends perpendicular to the running direction of the drain pipe 10. One end of the rotating rod 42 is rotatably inserted into the top of the rotating rod fixing frame 41. One end of the connecting plate 45 is sleeved on the other end of the rotating rod 42. The encoder 44 and the measuring wheel 43 are installed on the other end of the connecting plate 45 in a left-right relative manner. The encoder 44 and the measuring wheel 43 are located between the rotating rod 42 and the conveying wheel 2.

[0085] During measurement, the wheel surface of the measuring wheel 43 rubbing against the top surface of the drain pipe 10 is located below the outer peripheral bottom surface of the rotating rod 42 .

[0086] like Figure 2 and Figure 4 As shown, one end of the rotating rod 42 is rotatably inserted into the top of the rotating rod fixing frame 41, so that the encoder 44 and the measuring wheel 43 can be lifted when not in use, which can improve the operational convenience of inserting the drain pipe 10 between the conveying wheel 2 and the measuring wheel 43.

[0087] The arrangement of the wheel surface of the measuring wheel 43 that rubs against the top surface of the drain pipe 10 and is located below the outer peripheral bottom surface of the rotating rod 42 can make the center of gravity of the measuring wheel 43 lower than the center of gravity of the rotating rod 42, thereby preventing the measuring wheel 43 from tilting upward during measurement, and improving the operating stability and measurement accuracy of the measuring wheel 43.

[0088] Furthermore, the electric cutting machine 5 further includes a housing 51 and a cutting blade driving motor 53;

[0089] The rotary cutter 54 includes a cutter holder 542 and two blades 541;

[0090] The drain pipe holder 52 is further provided with a cutting groove 520;

[0091] The cutting blade drive motor 53 is mounted outside the housing 51, and the input end of the cutting blade drive motor 53 extends backward into the housing 51 and is connected to the middle of the blade holder 542;

[0092] The blade holder 542 and the blade 541 extend in directions perpendicular to the extending direction of the clamping slot 541 , and the blades 541 are mounted on both ends of the blade holder 542 ;

[0093] The cutting groove 520 penetrates the drain pipe holder 52 and the clamping groove 541 from top to bottom; the cutting groove 520 is located in the inner cavity of the housing 51; the drain pipe holder 52 penetrates the housing 51 from front to back;

[0094] The cutting blade driving motor 53 is connected to the encoder 44 for signal communication.

[0095] like Figure 5 As shown, the cutting blade drive motor 53 starts after receiving the feedback signal from the encoder 44 that the measured length reaches the set threshold, and drives the blade holder 542 and the two blades 541 to rotate one circle to cut off the drainage pipe 10 located in the clamping groove 541.

[0096] The rotary cutter 54 is arranged in the housing 51 , which can improve the operating safety of the rotary cutter 54 .

[0097] Furthermore, the electric cutting machine 5 also includes a sensor 55;

[0098] The sensor 55 is installed on the housing 51 , and the sensing end of the sensor 55 extends into the housing 51 . The sensing end of the sensor 55 is used to align the unactivated tool holder 542 and detect the movement and reset of the corresponding tool holder 542 .

[0099] like Figure 5As shown, the sensor 55 can be used to determine whether the start-up and reset of the blade holder 542 are normal, and the number of rotations of the blade holder 542 during operation can be counted, thereby determining the operating status of the electric cutting machine 5 and the number of times the drain pipe 10 is cut, providing convenience for equipment monitoring and production data statistics.

[0100] In summary, if Figure 1-5 In the embodiment of the utility model shown, the drain pipe cutting equipment measures the cutting length of the drain pipe 10 through the encoder 44 and the measuring wheel 43, and completes the fixed-length cutting of the drain pipe 10 through the cooperation of the encoder 44 and the electric cutting machine 5. The cut drain pipe 10 can also be unloaded through the unloading component 62, which can not only ensure the consistency of the cutting length of the drain pipe 10, but also improve the production speed of the drain pipe cutting.
