[0026] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1-4 As shown, a floor heating pipe cutting device comprises a support 1, on which a pipe clamping mechanism, a driving mechanism, a guide rail mechanism and a cutting mechanism are arranged, the pipe clamping mechanism comprises two symmetrically arranged pipe clamping plates 2 and a driving gear 28, opposite sides of the two pipe clamping plates 2 are respectively provided with a pipe clamping groove, the guide rail mechanism is arranged on the outside of the pipe clamping groove and fixed on the side of the pipe clamping plate 2, the cutting mechanism is arranged on the guide rail mechanism, the driving mechanism is arranged on the back of the pipe clamping plate 2 and connected with the cutting mechanism through the driving gear 28, so that the cutting mechanism can move along the guide rail mechanism;

[0028] A translation plate 21 is fixedly provided on the bottom surface of the tube clamping plate 2, and the translation plate 21 cooperates with the spiral thread on one side of the bidirectional lead screw 5. Two first fixed plates 6 are fixedly provided on the support 1, and the two first fixed plates 6 are respectively rotatably cooperated with the two sides of the bidirectional lead screw 5. Two inner sleeve columns 4 are sleeved in the translation plate 21, and the two inner sleeve columns 4 are fixed between the two first fixed plates 6.

[0029] As an optional embodiment, four symmetrically distributed inner pressure plates 23 are provided on opposite sides of the two tube clamping plates 2, and rubber columns 24 are fixed on the side surfaces of the inner pressure plates 23, and the rubber columns 24 are fixed on the tube clamping grooves. Support plates 7 are provided correspondingly at the front and rear of the two tube clamping plates 2, and the bottom surfaces of the support plates 7 are fixed to the vertical plates 71, and the vertical plates 71 are fixed on the support 1. With such an arrangement, by adjusting the pipe clamping mechanism, when the two tube clamping plates 2 are brought close to each other, the inner pressure plates 23 can be driven to clamp the floor heating pipes, and the inner pressure plates 23 can be elastically contracted by the rubber columns 24, so as to facilitate the synchronous clamping of the floor heating pipes when the floor heating pipes are on the support plates 7.

[0030] See attached Figure 2 The driving mechanism includes three first rotating shafts 27, which are evenly distributed on the outside of the pipe clamping groove. The three first rotating shafts 27 are all rotatably matched with the pipe clamping plate 2. Two connecting gears 29 are provided on the side of the pipe clamping plate 2. The two connecting gears 29 are respectively fixed to two of the first rotating shafts 27 on the upper and lower sides, and the two horizontal connecting gears 29 are meshed and matched. In this way, the two driving mechanisms can rely on the adjustment of the pipeline clamping mechanism to drive the two horizontal corresponding connecting gears 29 on the two driving mechanisms to mesh and connect, so that it is convenient to drive the driving gears 28 on the two driving mechanisms to rotate synchronously by operating any one of the driving mechanisms.

[0031] Furthermore, a second rotating shaft 211 is provided on the side of the tube plate 2, and the second rotating shaft 211 is rotatably matched with the second fixed plate 22. The second fixed plate 22 is fixedly arranged on the side of the tube plate 2, and the second rotating shaft 211 is connected with three pulley groups 210, and the three pulley groups 210 are respectively connected with the three first rotating shafts 27. The pulley group 210 includes a transmission belt and two pulleys, and the transmission belt is sleeved on the two pulleys. The pulleys are connected to both the second rotating shaft 211 and the first rotating shaft 27. A hand wheel is fixedly arranged on the second rotating shaft 211. In this way, the second rotating shaft 211 can be driven to rotate synchronously by operating the hand wheel, and the second rotating shaft 211 can drive the driving gears 28 on the three first rotating shafts 27 to rotate synchronously through the three pulley groups 210, so that the driving gear 28 can mesh with the toothed plate 35.

[0032] Furthermore, three driving gears 28 and a toothed plate 35 are provided on the other side of the tube clamping plate 2. The three driving gears 28 are respectively connected to the three first rotating shafts 27. The three driving gears 28 are all meshed and matched with the toothed plate 35. The toothed plate 35 is connected to the guide rail mechanism. The shape of the toothed plate 35 is set to be arc-shaped. The arc length of the toothed plate 35 is greater than the arc spacing between the two driving gears 28. Such a setting makes it easy to deal with the guide rail mechanism driving the toothed plate 35 to move semicircularly. The toothed plate 35 can be meshed and connected with the driving gear 28 during the movement, thereby not affecting the semicircular movement of the guide rail mechanism.

[0033] See attached Figure 3 The guide rail mechanism includes an arc groove plate 33, the outer side surface of the arc groove plate 33 is fixed to the tooth groove plate 35, the side surface of the arc groove plate 33 is provided with a groove, and a plurality of inner rotating rings 26 are sleeved in the arc groove plate 33. Two blocking plates 34 are fixed on the inner groove surface formed on the arc groove plate 33, and the two blocking plates 34 correspond to the position of each inner rotating ring 26. A plurality of guide rail shafts 25 are fixed on the side surface of the tube clamping plate 2, and the plurality of guide rail shafts 25 are evenly distributed on the outer side of the tube clamping groove, and each guide rail shaft 25 is rotatably matched with the inner rotating ring 26. In this way, when the arc groove plate 33 is driven by the tooth groove plate 35 to move in a semicircle, the blocking plate 34 is used to restrict the arc groove plate 33 from being separated from the guide rail shaft 25. At the same time, the inner rotating ring 26 can form a rolling connection with the inside of the arc groove plate 33, thereby improving the smoothness of the arc groove plate 33 when driving the cutting mechanism to move in a semicircle.

[0034] See attached Figure 4 The arc groove plate 33 is connected to the cutting mechanism, and the cutting mechanism includes a motor 3. The output shaft of the motor 3 is fixed to the transmission shaft 31. A cutting wheel 32 is arranged on the transmission shaft 31. The transmission shaft 31 rotates with the arc groove plate 33. A mounting bracket 36 is arranged on the side of the arc groove plate 33. The mounting bracket 36 is connected to the motor 3. A wire sleeve 8 is arranged on the side of the arc groove plate 33. The wire sleeve 8 is fixed on the support 1. The position of the wire sleeve 8 corresponds to that of the motor 3. A connecting wire for starting the motor 3 is sleeved in the wire sleeve 8. With such a setting, when the guide rail mechanism drives the cutting mechanism to move in a semicircle, the connecting wire of the starting motor 3 can be restrained, thereby avoiding entanglement with the floor heating pipe and avoiding contact with the cutting wheel 32.

[0035] Furthermore, a positioning plate 37 is fixedly provided at the center of the side of the arc groove plate 33, and the positioning plate 37 is set to be L-shaped. The arc groove plate 33 is correspondingly provided with a blocking shaft 212, which is fixed to the side of the tube clamping plate 2, and the blocking shaft 212 is matched with the positioning plate 37. The blocking shaft 212 is arranged outside the circular trajectory of the arc groove plate 33 moving along the guide shaft 25, and is misaligned with the circular motion trajectory of the tooth groove plate 35. The length of the positioning plate 37 is set to be greater than the distance between the blocking shaft 212 and the circumferential distribution axis of the guide shaft 25. The positioning plate 37 is misaligned with the side of the driving gear 28, and the length of the blocking shaft 212 is set close to the side of the cutting wheel 32 and does not contact it. With this arrangement, the arc groove plate 33 on the guide rail mechanism can be positioned by relying on the positioning plate 37, so that when the two guide rail mechanisms move semicircularly synchronously, the two guide rail mechanisms can drive the two cutting mechanisms to move synchronously, so that the two cutting mechanisms correspond head to tail after moving, thereby achieving the effect of circular cutting separation.

[0036] Working principle: Place the floor heating pipe on two support plates 7, and then rotate the bidirectional lead screw 5 to drive the pipe clamping plate 2 on the translation plate 21 to move relatively, so that the inner pressure plate 23 on the pipe clamping plate 2 presses the floor heating pipe. At the same time, when the two pipe clamping plates 2 are close to each other, the connecting gears 29 on the two driving mechanisms form a meshing connection, so that the floor heating pipe can be fixed between the two cutting mechanisms for cutting operation;

[0037] Then rotate the second rotating shaft 211 on the driving mechanism so that the rotating second rotating shaft 211 drives the three first rotating shafts 27 to rotate synchronously through the three pulley groups 210, and the three first rotating shafts 27 drive the driving gear 28 and the connecting gear 29 to rotate synchronously, thereby driving the driving gears 28 on the two driving mechanisms to rotate synchronously through the connecting gear 29, and then the rotating driving gear 28 engages to drive the toothed plate 35 to move, so that the toothed plate 35 drives the arc groove plate 33 on the guide rail mechanism to move in a semicircle along the guide rail shaft 25 and the inner ring, so that the arc groove plate 33 can drive the cutting mechanism to move synchronously, so that the cutting wheels 32 on the two cutting mechanisms can perform ring cutting on the floor heating pipes to cut and separate the floor heating pipes.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
