[0038] The present application provides a pipe cutting device, which aims at setting a cutting mechanism between a guiding mechanism and a supporting mechanism, so that the guiding mechanism and the supporting mechanism jointly support the pipe during cutting, facilitating cutting, and the supporting mechanism can support pipes of different specifications, having wide application range and high practicability.

[0039] Please refer to Figures 1 to 2 The specific structure of the pipe cutting device 10 provided by the present application will be described below in specific embodiments. In an embodiment of the present application, the pipe cutting device 10 comprises:

[0040] a rack 1;

[0041] a linear motion mechanism 2 installed on the rack 1;

[0042] a guiding mechanism 3 installed on the linear motion mechanism 2 and used for passing the pipe therethrough;

[0043] a supporting mechanism 5 installed on the linear motion mechanism 2 and arranged in a spaced manner with the guiding mechanism 3 to support the pipe;

[0044] a cutting mechanism 6 installed on the linear motion mechanism 2 and located between the guiding mechanism 3 and the supporting mechanism 5, and used for cutting the pipe; and

[0045] wherein the linear motion mechanism 2 drives the guiding mechanism 3, the cutting mechanism 6 and the supporting mechanism 5 to reciprocally move linearly relative to the rack 1.

[0046] As known, the pipe cutting device is used for cutting the formed pipe 4 to a specific length, and the main components thereof are the cutting mechanism 6 and the guiding mechanism 3. After the pipe 4 is formed, it is sent out through the guiding of the guiding mechanism 3, and when the extension length of the pipe 4 reaches the set requirement, the pipe 4 is cut by the cutting mechanism 6, so as to obtain the pipe 4 of corresponding length.

[0047] In this embodiment, the pipe cutting device 10 further comprises a linear motion mechanism 2 installed on the rack 1, and the guide mechanism 3 is installed on the linear motion mechanism 2 for the pipe 4 to pass through, and the cutting mechanism 6 is movably installed on the end of the guide mechanism 3 out of the pipe 4. Since the generated pipe 4 is continuously spirally advancing, the guide mechanism 3 and the cutting mechanism 6 are driven by the linear motion mechanism 2 to advance at the same speed as the pipe 4, so that the cutting mechanism 6 can timely and smoothly cut the pipe 4 according to the specific length, and can completely cut the pipe 4 without damaging the pipe 4, avoiding unevenness at the cut of the pipe 4. It should be noted that the linear motion mechanism 2 comprises a linear motion group and a first driving group, and the first driving group can comprise a motor and a speed reducer, and the motor is drivingly connected to the speed reducer, and the speed reducer is drivingly connected to the linear motion group. It can be understood that the linear motion group can be composed of a screw rod and a sliding block, wherein the output shaft of the speed reducer is drivingly connected to the screw rod, the sliding block is movably connected to the screw rod, and the sliding block realizes linear movement through the screw rod.

[0048] Specifically, in order to facilitate further stable cutting operation of the pipe 4, the pipe cutting device 10 further comprises a supporting mechanism 5 installed on the other end of the linear motion mechanism 2 to support the pipe 4, that is, one end of the generated pipe 4 is placed on the supporting mechanism 5 through the guide mechanism 3, and the next end of the generated pipe 4 is guided out through the guide mechanism 3, and then the two ends of the pipe 4 are positioned through the guide mechanism 3 and the supporting mechanism 5, so that the cutting mechanism can cut the pipe 4, which can effectively avoid the deviation of the pipe 4 during cutting, thereby reducing the cutting precision of the pipe 4. In this embodiment, the pipe 4 is a plastic pipe made of a wire material such as high-density polyethylene.

[0049] Further, in order to smoothly cut the pipe 4 during the spiral advancement of the pipe 4, the supporting mechanism 5 also advances at the same speed as the pipe 4 under the driving of the linear motion mechanism 2. Therefore, when one end of the pipe 4 is placed on the supporting mechanism 5, since the pipe 4 is in a continuous spiral advancement state, the guide mechanism 3, the supporting mechanism 5 and the cutting mechanism 6 advance with the pipe 4 under the driving of the linear motion mechanism 2, and in the process of advancing, the cutting mechanism 6 can quickly and timely cut the pipe 4, and then the guide mechanism 3, the supporting mechanism 5 and the cutting mechanism 6 return to the original route under the driving of the linear motion mechanism 2, and advance again with the next newly produced pipe 4 and cut it.

[0050] Please refer to Figures 1 to 2 In an optional embodiment, the pipe cutting device 10 further comprises a mounting plate 7 slidably connected to the linear motion mechanism 2.

[0051] The support mechanism 5 comprises a first limiting assembly 51 and a support assembly 52. The first limiting assembly 51 is movably installed on the mounting plate 7. The support assembly 52 is installed on the first limiting assembly 51. The distance between the support assembly 52 and the cutting mechanism 6 can be adjusted through the first limiting assembly 51. Thus, the distance between the support assembly 52 and the cutting mechanism 6 can be changed. The support mechanism 5 can support the pipe 4 with different cutting lengths. Thus, the cutting mechanism 6 can cut the pipe 4 with different lengths to meet different production requirements.

[0052] In the embodiment, the mounting plate 7 moves with the linear motion mechanism 2. The support mechanism 5 comprises the first limiting assembly 51 and the support assembly 52. The first limiting assembly 51 is movably installed on the mounting plate 7. The support assembly 52 is installed on the first limiting assembly 51. The distance between the support assembly 52 and the cutting mechanism 6 can be adjusted through the first limiting assembly 51. Thus, the distance between the support assembly 52 and the cutting mechanism 6 can be changed. The support mechanism 5 can support the pipe 4 with different cutting lengths. Thus, the cutting mechanism 6 can cut the pipe 4 with different lengths to meet different production requirements.

[0053] It should be noted that the linear motion mechanism 2 comprises a driving motor (not shown), a speed reducer (not shown), and a linear motion group (not shown). The driving motor is drivingly connected to the speed reducer. The speed reducer is drivingly connected to the linear motion group. It can be understood that the linear motion group can be composed of a screw rod and a sliding block. The output shaft of the speed reducer is drivingly connected to the screw rod. The sliding block is movably connected to the screw rod. The sliding block is connected to the mounting plate 7. The linear movement of the mounting plate 7 can be realized through the driving motor, the speed reducer, and the screw rod. Thus, the guiding mechanism 3, the support mechanism 5, and the cutting mechanism 6 can follow the pipe 4 to move forward.

[0054] Please refer to Figure 2 In an optional embodiment, the first limiting assembly 51 comprises a mounting seat 511, two first guide rods 512, and a first fixed block 513. The mounting seat 511 is fixedly installed on the mounting plate 7. One end of each of the two first guide rods 512 is movably installed on the mounting seat 511. The other end of each of the two first guide rods 512 is connected to the first fixed block 513.

[0055] The support mechanism 5 further comprises a plurality of distance adjusting members 53. Two distance adjusting members 53 are movably installed on the two sides of the mounting seat 511 through the first guide rods 512. The support assembly 52 can move towards or away from the pipe 4. The first guide rods 512 can be moved by loosening the two distance adjusting members 53. Thus, the support assembly 52 can move towards or away from the guiding mechanism 3. The distance between the support assembly 52 and the guiding mechanism 3 can be adjusted. Thus, the support assembly 52 can support the pipe 4 with different cutting lengths. Thus, the pipe 4 with different lengths can be cut to meet the actual production requirements.

[0056] In the embodiment, the first limiting assembly 51 comprises a mounting base 511, two first guide rods 512 and a first fixing block 513. The two first guide rods 512 are movably arranged in the mounting base 511 and are mounted on the mounting plate 7 through the mounting base 511. The first fixing block 513 is arranged at the end of the two first guide rods 512 away from the mounting base 511, so as to fixedly connect the two first guide rods 512 through the first fixing block 513, thereby ensuring the connection stability between the two first guide rods 512.

[0057] Specifically, in order to conveniently adjust the position of the two first guide rods 512, the supporting mechanism 5 further comprises a plurality of distance adjusting pieces 53. Two distance adjusting pieces 53 are movably arranged on the two sides of the first guide rod 512 passing through the mounting base 511, so as to adjust the position of the first guide rod 512 by loosening the two distance adjusting pieces 53, thereby moving the supporting assembly 52 away from or close to the guiding mechanism 3. When the length of the pipe 4 to be cut is short, the supporting assembly 52 needs to be moved close to the guiding mechanism 3 to support the pipe 4. The first guide rod 512 can be moved towards the guiding mechanism 3 by loosening the two distance adjusting pieces 53, thereby stably placing the pipe 4 passing through the guiding mechanism 3 on the supporting mechanism 5. After completion, the two distance adjusting pieces 53 are tightened to tightly fit on the two ends of the first guide rod passing through the mounting base, thereby fixing the first guide rod on the mounting base 511. Similarly, when the length of the pipe 4 to be cut is long, the supporting assembly 52 needs to be moved away from the guiding mechanism 3 to support the pipe 4. The first guide rod 512 is moved away from the guiding mechanism 3 by loosening the two distance adjusting pieces 53, thereby stably placing the pipe 4 passing through the guiding mechanism 3 on the supporting mechanism 5. After completion, the two distance adjusting pieces 53 are tightened to tightly fit on the two ends of the first guide rod passing through the mounting base, thereby fixing the first guide rod on the mounting base 511. By arranging the two distance adjusting pieces 53, the position of the first guide rod 512 can be quickly adjusted, and after adjustment, the first guide rod 512 can be locked again to ensure the stable installation of the supporting assembly 52, which is simple and convenient to operate.

[0058] It can be understood that the mounting base 511 is provided with a through hole (not shown) for the first guide rod 512 to pass through. In order to prevent wear between the first guide rod 512 and the mounting base 511 during adjustment of the first guide rod 512, a linear bearing can be arranged in the through hole, and the first guide rod 512 passes through the inner wall of the linear bearing, so as to prevent direct contact between the first guide rod 512 and the hole wall of the through hole. Since the linear bearing is internally provided with balls, the friction and wear of the first guide rod 512 are further reduced.

[0059] Please refer to Figure 2In optional embodiments, the supporting mechanism 5 further comprises a second limiting assembly 54 and a first guide block 514, the first guide block 514 is arranged between the first fixing block 513 and the mounting base 511; the first limiting assembly 51 is connected to the second limiting assembly 54 through the first guide block 514, and the supporting assembly 52 is mounted on the second limiting assembly 54, so as to further adjust the distance between the supporting assembly 52 and the cutting mechanism 6 through the second limiting assembly 54, thereby adapting to more pipe materials 4 of different cutting sizes, and meeting the actual production needs.

[0060] In the embodiments, in order to further adjust the distance between the supporting assembly 52 and the cutting mechanism 6, so that the supporting assembly 52 supports more pipe materials 4 of different cutting sizes, the second limiting assembly 54 is arranged, and the first limiting assembly 51 is connected to the second limiting assembly 54 through the first guide block 514, and the distance between the supporting assembly 52 and the guide mechanism 3 is further adjusted through the second limiting assembly 54.

[0061] Specifically, in order to improve the connection stability between the first guide rod 512 and the first guide block 514, two distance adjusting pieces 53 can also be arranged at the connection between the first guide rod 512 and the first guide block 514, and one side of the first guide block 514 is fixedly mounted on the first guide rod 512 through the two distance adjusting pieces 53, thereby improving the connection stability between the first limiting assembly 51 and the second limiting assembly 54.

[0062] Please refer to Figure 2 In optional embodiments, the supporting mechanism 5 further comprises a second guide block 543, the second guide block 543 is mounted on the second limiting assembly 54 away from the first guide block 514, and the supporting assembly 52 is movably mounted on the second guide block 543, so as to stably mount the supporting assembly 52 on the second limiting assembly 54.

[0063] In the embodiments, in order to facilitate the installation between the supporting assembly 52 and the second limiting assembly 54, the supporting mechanism 5 further comprises the second guide block 543, the second guide block 543 is mounted on the second limiting assembly 54, and the supporting assembly 52 is movably mounted on the second guide block 543, thereby the distance between the supporting assembly 52 and the guide mechanism 3 can be further adjusted through the first limiting assembly 51 and the second limiting assembly 54, so as to adapt to more pipe materials 4 of different lengths.

[0064] Please refer to Figure 2 In optional embodiments, the second limiting assembly 54 comprises two second guide rods 541 and a second fixing block 542, one end of the two second guide rods 541 is connected to the second guide block 543, the other end of the two second guide rods 541 is connected to the second fixing block 542, and the first guide block 514 is arranged between the second guide block 543 and the second fixing block 542.

[0065] The other two distance adjusting members 53 are arranged on both sides of the second guide rod 541 penetrating through the first guide block 514, so as to further adjust the moving direction of the support assembly 52 towards or away from the pipe 4, so as to adapt to more pipe 4 with different cutting sizes, and meet the actual production needs.

[0066] In the embodiment, the second limiting assembly 54 further comprises two second guide rods 541 and a second fixing block 542, and the other ends of the two second guide rods 541 are connected to the second fixing block 542, so as to fix the two second guide rods 541 through the second fixing block 542, and further ensure the connection stability between the two second guide rods 541.

[0067] Specifically, in order to further adjust the distance between the support assembly 52 and the guide mechanism 3, the other two distance adjusting members 53 are arranged on both sides of the second guide rod 541 penetrating through the first guide block 514, so as to adjust the position of the second guide rod 541 by loosening the two distance adjusting members 53, and further drive the support assembly 52 to move further away from or close to the guide mechanism 3. When the pipe 4 needs to be cut to a shorter length, and the distance between the support assembly 52 and the guide mechanism 3 cannot be further adjusted through the first guide rod 512, the support assembly 52 needs to be moved further towards the guide mechanism 3 to meet the support of the support assembly 52 to the pipe 4, therefore, the second guide rod 541 is moved towards the guide mechanism 3 by loosening the two distance adjusting members 53, so that the end of the pipe 4 penetrating through the guide mechanism 3 can be stably placed on the support mechanism 5, thereby adapting to the pipe 4 with a shorter cutting length, and then the two distance adjusting members 53 are tightened again to tightly fit the two distance adjusting members 53 on both sides of the second guide rod penetrating through the first guide block 514, so as to fix the second guide rod on the first guide block 514 again. Similarly, when the pipe 4 needs to be cut to a longer length, and the distance between the support assembly 52 and the guide mechanism 3 cannot be further adjusted through the first guide rod 512, the support assembly 52 needs to be moved further away from the guide mechanism 3 to meet the support of the support assembly 52 to the pipe 4, and the second guide rod 541 is moved away from the guide mechanism 3 by loosening the two distance adjusting members 53, so that the end of the pipe 4 penetrating through the guide mechanism 3 can be stably placed on the support mechanism 5, and then the two distance adjusting members 53 are tightened again to tightly fit the two distance adjusting members 53 on both sides of the second guide rod penetrating through the first guide block 514, so as to fix the second guide rod on the mounting seat 511 again. By arranging the distance adjusting members 53, the position of the second guide rod 541 can be quickly adjusted, and after the adjustment is completed, the second guide rod 541 can also be locked again to ensure the stable installation of the support assembly 52, which is simple and convenient to operate.

[0068] It can be understood that the mounting hole (not shown) is formed on the first guide block 514, so that the second guide rod 541 is inserted, in order to prevent the wear between the second guide rod 541 and the first guide block 514 when adjusting the second guide rod 541, a linear bearing can be provided in the through hole, and the second guide rod 541 is inserted into the inner wall of the linear bearing, so as to prevent direct contact between the second guide rod 541 and the hole wall of the mounting hole, and since the linear bearing is provided with a plurality of rolling balls, the friction and wear of the second guide rod 541 are further reduced.

[0069] Please refer to Figure 2 In an optional embodiment, the support assembly 52 comprises a base 521 and two support members 522, one end of the base 521 movably mounting the two support members 522, and the other end of the base 521 movably mounting the second guide block 543, so that the two support members 522 move up and down perpendicular to the movement direction of the pipe 4, thereby supporting the pipe 4 of different thicknesses.

[0070] In this embodiment, the support assembly 52 comprises a base 521 and two support members 522, and one end of the base 521 is movably mounted on the second guide block 543, i.e. the base 521 is detachably mounted on the second guide block 543, so that the base 521 moves up and down perpendicular to the movement direction of the pipe 4, thereby enabling the support members 522 to support the pipe 4 of different thicknesses. It should be noted that the base 521 can be detachably mounted on the fixed seat 31 by means of screws or the like, so that the mounting height of the base 521 can be adjusted at any time, so that the pipe 4 of different diameters can pass through the two support members 522 smoothly, which is simple and convenient to operate. Of course, other detachable connection methods can also be used, which are not limited in the present application.

[0071] Please refer to Figure 2 In an optional embodiment, the base 521 is formed with a mounting groove 5211, and the two support members 522 are rotatably connected in the mounting groove 5211, and a space is formed between the two support members 522, so that the pipe 4 can pass through smoothly.

[0072] In this embodiment, a groove for supporting the pipe 4 is formed between the two support members 522, and preferably, the support member 522 is a ball bearing, which has a smooth surface, not only supporting the rotation of the pipe 4, but also effectively reducing the wear between the pipe 4 and the support member 522. The two support members 522 can rotate under the action of the pipe 4 advancing spirally, without affecting the advancement of the pipe 4, and further reducing the wear of the pipe 4, ensuring the quality of the finished pipe 4. Of course, the support member 522 can also be a roller or the like.

[0073] Please refer to Figures 1 to 2 In an optional embodiment, the linear motion mechanism 2 is mounted on one surface of the mounting plate 7, and the guide mechanism 3 is mounted on the other surface of the mounting plate 7.

[0075] In this embodiment, in order to smoothly guide the pipe 4 into the pipe cutting device, the guiding mechanism 3 comprises a fixed seat 31 and a guiding die 32, the fixed seat 31 is installed on one end of the mounting plate 7, and the guiding die 32 is movably installed on the fixed seat 31, and the guiding die 32 is used for the pipe 4 to pass through. Therefore, the guiding die 32 is provided with a through hole, and the pipe 4 enters the pipe cutting device 10 through the through hole and is cut off by the cutting mechanism 6. It can be understood that the diameter of the through hole is slightly larger than the diameter of the pipe 4, so that the pipe 4 can be smoothly passed through the through hole. In this embodiment, the guiding die 32 is made of plastic material, preferably nylon. In this way, when the pipe 4 passes through the guiding die 32, the surface of the pipe 4 is not easily worn, and the quality of the finished pipe 4 is guaranteed.

[0076] It should be noted that the guiding die 32 can be detachably installed on the fixed seat 31 by screws, buckles or other means, so that the guiding die 32 with different diameters can be replaced at any time to make the pipe 4 with different diameters pass through the guiding die 32 smoothly. The operation is simple and convenient, and of course other detachable connection methods can also be used, which are not limited in the present application.
