Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, and in particular to a pipe cutting device with a fixed length function. Background Technology

[0002] Pipe length cutting is a process that uses specialized equipment to precisely control the cutting length and speed. Commonly used equipment includes PVC pipe cutting machines, automatic pipe cutting machines, and electric pipe cutting machines. It is suitable for various materials such as PVC, metal, silicone, and heat shrink tubing, and the cutting accuracy can reach 0.1 mm. It supports batch grouping and automatic counting functions.

[0003] A search revealed Chinese patent CN209255992U, which discloses a pipe cutting device, specifically a pipe length-fixing device. It includes a pipe length measuring device and a pipe cutting device. The pipe length measuring device comprises a support, a detection wheel and a pressing wheel mounted on the support, a magnet mounted on the detection wheel, a sensing probe mounted on the support and corresponding to the detection wheel, and a counter. The pressing wheel is located above the detection wheel, and the sensing probe is connected to the counter. Integrating the pipe length measuring device and the pipe cutting device into one unit, using the pipe length measuring device to determine the pipe cutting length, and then using the pipe cutting device for cutting, can significantly improve the efficiency of pipe measurement and cutting, and is convenient and quick to use. However, in practical use, this solution still has the following shortcomings: The aforementioned device, through the coordinated operation of components such as the detection wheel, can accurately measure and cut the length of pipes, meeting the processing needs of pipes of different specifications and lengths. However, in actual pipe cutting operations, especially when cutting large-diameter rubber pipes, due to the large diameter of these pipes and the relatively soft material used in their manufacture, the pipe cannot maintain its original stable shape when the cutting tool contacts it, and is prone to deformation. This deformation is complex and difficult to control precisely, directly leading to deviations in the cutting position, seriously affecting the accuracy of the cutting, and ultimately resulting in pipes that fail to meet high-quality production requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the production of large-diameter rubber pipes, due to the large diameter and the relatively soft material, the pipe is difficult to maintain a stable shape when the cutting tool contacts the pipe, and is prone to complex and uncontrollable deformation. This deformation directly causes deviation in the cutting position, which greatly affects the cutting accuracy. To address this, we propose a cutting device with a pipe length setting function.

[0005] To achieve the above objectives, this application adopts the following technical solution: a cutting device with pipe length fixing function, comprising a base and two drive rollers symmetrically arranged on the top surface of the base. The top surface of the base has two guide grooves symmetrically opened, and a drive seat is provided on the inner side of each of the two guide grooves. A control electric push rod is fixedly installed on the top surface of the drive seat. A support plate is fixedly installed on the telescopic end of the two control electric push rods. A circular saw is provided on the support plate. A circular saw cover is provided on the outer side of the circular saw blade of the circular saw. A chip removal assembly is provided on the circular saw cover. A linkage rod corresponding to the two drive rollers is provided on the side of the base. A plurality of positioning components are provided on the outer wall of the linkage rod. The chip removal assembly includes several slots corresponding to the circular saw blade at the bottom of the circular saw cover, and baffles are slidably installed on the inner wall of the slots. The circular saw cover is provided with a chip suction structure. The positioning component includes a sliding sleeve that is slidably fitted onto the outer wall of the linkage rod via a sliding groove and a slider. A threaded sleeve is rotatably installed at the end of the sliding sleeve, and the threaded sleeve is screwed to the linkage rod. Two sets of support structures are symmetrically arranged on the outer wall of the sliding sleeve.

[0006] Preferably, the baffle has a ball mounting groove at one end located outside the slot, and a supporting ball is movably mounted on the inner wall of the ball mounting groove.

[0007] Preferably, the dust collection structure includes a dust collection shell that extends through the outer wall of the circular saw cover, and a dust collection pump is fixedly installed on the top surface of the support plate. The suction end of the dust collection pump is connected to the dust collection shell through a dust collection pipe.

[0008] Preferably, the support structure includes a drive electric actuator fixedly installed on the outer wall of the sliding sleeve. A plurality of follower telescopic rods are fixedly installed on the outer wall of the sliding sleeve. The plurality of follower telescopic rods and the drive electric actuator are arranged in a circular array on the outer wall of the sliding sleeve. The telescopic ends of the drive electric actuator and the plurality of follower telescopic rods are symmetrically fixedly installed with two mounting seats. A connecting telescopic rod is fixedly installed between the two opposing mounting seats. The telescopic ends of the drive electric actuator and the plurality of follower telescopic rods are fixedly installed with a stop block.

[0009] Preferably, the outer wall of the abutment is arc-shaped and has anti-slip texture.

[0010] Preferably, the outer wall of the sliding sleeve is provided with a chip collection assembly located between the two sets of support structures.

[0011] Preferably, the chip collection assembly includes a plurality of arc-shaped retaining covers fixedly installed between two opposing blocks. Each arc-shaped retaining cover has a mounting groove at both ends. A connecting retaining cover is slidably installed between two adjacent mounting grooves and is fixedly connected to the blocks. The inner wall of the connecting retaining cover has a receiving port. A transfer hopper corresponding to the receiving port is fixedly installed on the side of the connecting retaining cover. A collection box is provided at the end of the transfer hopper, and a locking structure is provided on the inner side of the collection box.

[0012] Preferably, the material locking structure includes a fixed rod fixedly installed on the inner wall of the discharge end of the material conveying hopper, a guide rod fixedly installed on the bottom surface of the fixed rod, a limit plate fixedly installed at the bottom end of the guide rod, and a sealing plate slidably fitted on the outer wall of the guide rod.

[0013] Preferably, the side of the sealing plate is in contact with the inner wall of the feed hopper.

[0014] Preferably, a guide opening is provided on the side of the base, and a linkage electric actuator corresponding to the guide opening is fixedly installed on the side of the base. The end of the linkage rod passes through the guide opening and is rotatably connected to the telescopic end of the linkage electric actuator.

[0015] The technical effects and advantages of this invention are as follows: In this invention, by activating the control electric actuator and the linkage electric actuator, the height of the cutting circular saw and the linkage rod can be flexibly adjusted to match the pipe material. Furthermore, adjusting the position of the sliding sleeve allows for precise alignment with the pipe cutting point. Simultaneously, the driving electric actuator moves the abutment blocks to provide circumferential support to the inner wall of the pipe, ensuring the cutting position is between the two abutment blocks. This multi-dimensional adjustment and support method effectively solves the problem of deviations during cutting of large-diameter pipes due to their soft texture and insufficient support. It ensures that the cutting circular saw can precisely cut the pipe according to the preset length and position, greatly improving cutting quality and meeting the demands of high-precision production. In this invention, during cutting, the baffle on the bottom of the circular saw cover moves down and slides according to the contact with the pipe, located outside the circular saw blade at the cutting point, which can prevent the outer wall debris from splashing. At the same time, the dust pump is turned on, and the dust is promptly sucked up by the dust suction pipe and dust suction shell. For the inner side of the pipe, the arc-shaped clamp and the connecting clamp move with the stop block and contact the inner wall of the pipe synchronously, collecting the splashed debris, which enters the collection box through the receiving port and the transfer hopper. The limiting plate slides automatically according to the orientation of the receiving port to prevent the debris from being discharged, effectively collecting the cutting debris, which is convenient for subsequent processing. In this invention, the linkage rod is precisely positioned at the center of the pipe, providing stable support for the overall cutting structure. The driving electric push rod moves the abutment block synchronously, providing uniform support to the inner wall of the pipe. This ensures that the pipe can rotate stably during cutting and will not shake due to uneven force. The arc-shaped clamp and connecting clamp are made of plastic material, which can flexibly deform with the movement of the abutment block and fit tightly against the inner wall of the pipe, further enhancing the support and fixation effect on the pipe. This all-round stable design effectively reduces interference factors in the cutting process and improves the stability and reliability of the operation. Attached Figure Description

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figure 1-3 As shown, the present invention provides a technical solution: a cutting device with pipe length fixing function, including a base 11 and two drive rollers 12 symmetrically arranged on the top surface of the base 11. Two guide grooves 13 are symmetrically opened on the top surface of the base 11. Drive seats 21 are provided on the inner side of each of the two guide grooves 13. Control electric push rods 22 are fixedly installed on the top surface of the drive seats 21. Support plates 23 are fixedly installed on the telescopic ends of the two control electric push rods 22. A circular saw 24 is provided on the support plate 23. A circular saw cover 31 is provided on the outer side of the circular saw blade of the circular saw 24. Linkage rods 53 corresponding to the two drive rollers 12 are provided on the side of the base 11. A guide opening 51 is opened on the side of the base 11. A linkage electric push rod 52 corresponding to the guide opening 51 is fixedly installed on the side of the base 11. The end of the linkage rod 53 passes through the guide opening 51 and is rotatably connected to the telescopic end of the linkage electric push rod 52.

[0020] First, the operator needs to adjust the device according to the diameter of the pipe being cut. During adjustment, the control electric actuator 22 and the linkage electric actuator 52 need to be activated to extend or shorten them. When the control electric actuator 22 is activated, it can drive the support plate 23 and the cutting circular saw 24 to the appropriate height. When the linkage electric actuator 52 is activated, it can drive the linkage rod 53 to move along the guide opening 51, thereby adjusting the height of the linkage rod 53 to correspond to the center of the pipe. After the material is loaded, the drive roller 12 and drive seat 21 can be activated. When the drive roller 12 is activated, it can drive the pipe to rotate. During the rotation, the drive seat 21 moves along the guide groove 13, driving the control electric push rod 22, the support plate 23, and the cutting circular saw 24 to move. When the cutting circular saw 24 moves to the cutting point, the control electric push rod 22 shortens, and the cutting circular saw 24 opens, which can cut the pipe through the circular saw blade, ensuring that the pipe can be accurately cut by the circular saw. With the cooperation of the drive seat 21 and the control electric push rod 22, the cutting circular saw 24 can cut the pipe to a fixed length with precision. The working principle and connection method of the drive roller 12 and the drive seat 21 are all existing mature technologies, and will not be described in detail here.

[0021] Reference Figure 3-5As shown, a chip removal assembly is provided on the circular saw cover 31. The chip removal assembly includes several slots 41 corresponding to the circular saw blade at the bottom of the circular saw cover 31. A baffle 42 is slidably installed on the inner wall of the slot 41. A ball mounting groove 43 is provided at one end of the baffle 42 located outside the slot 41. A supporting ball 44 is movably installed on the inner wall of the ball mounting groove 43. A chip suction structure is provided on the circular saw cover 31. The dust collection structure includes a dust collection shell 32 that runs through the outer wall of the circular saw cover 31, and a dust collection pump 33 is fixedly installed on the top surface of the support plate 23. The suction end of the dust collection pump 33 is connected to the dust collection shell 32 through a dust collection pipe 34.

[0022] During the cutting process, as the electric actuator 22 drives the support plate 23 and the circular saw 24 to move downwards and closer to the pipe, the support ball 44 on the bottom surface of the circular saw cover 31 on the outer side of the circular saw blade can first contact the pipe. As the circular saw cover 31 moves downwards, several baffles 42 can slide different distances along the slot 41 according to their contact with the pipe. The baffles 42 contact the outer wall of the pipe through the support ball 44 in the end-mounted ball groove 43, allowing the pipe to rotate normally. This ensures that when the circular saw blade is cutting, several baffles 42 can be located on the outside of the circular saw blade at the cutting point, avoiding the splashing of debris during the cutting process. At the same time, the dust pump 33 is turned on during cutting. The dust pump 33 can remove the debris generated inside the circular saw cover 31 through the dust suction pipe 34 and the dust suction shell 32, and discharge it through the discharge pipe.

[0023] Reference Figure 6 and Figure 7 As shown, the outer wall of the linkage rod 53 is provided with several sets of positioning components. The positioning components include a sliding sleeve 61 that is slidably fitted onto the outer wall of the linkage rod 53 through a sliding groove and a slider. A threaded sleeve 62 is rotatably installed at the end of the sliding sleeve 61, and the threaded sleeve 62 is screwed to the linkage rod 53. Two sets of support structures are symmetrically arranged on the outer wall of the sliding sleeve 61. The support structure includes a drive electric actuator 63 fixedly installed on the outer wall of the sliding sleeve 61. Several follower telescopic rods 64 are fixedly installed on the outer wall of the sliding sleeve 61. The follower telescopic rods 64 and the drive electric actuator 63 are arranged in a ring array on the outer wall of the sliding sleeve 61. Two mounting seats 65 are symmetrically fixedly installed on the telescopic ends of the drive electric actuator 63 and the several follower telescopic rods 64. A connecting telescopic rod 66 is fixedly installed between the two opposing mounting seats 65. A stop block 67 is fixedly installed on the telescopic ends of the drive electric actuator 63 and the several follower telescopic rods 64. The outer wall of the stop block 67 is arc-shaped and has anti-slip texture.

[0024] After adjusting the circular saw 24 and the linkage rod 53, the operator can adjust several sliding sleeves 61 on the linkage rod 53 according to the cutting situation, so that the positions of the sliding sleeves 61 correspond to the cutting points of the pipe. During adjustment, the threaded sleeve 62 can be rotated. The threaded sleeve 62 is screwed to the linkage rod 53 and rotatably connected to the sliding sleeve 61. The sliding sleeve 61 and the linkage rod 53 are slidably connected through a groove and a slider. Therefore, when the threaded sleeve 62 rotates, it can drive the sliding sleeve 61 to slide along the linkage rod 53 through the groove and slider, thereby adjusting the position of the sliding sleeve 61. After the adjustment is completed, the operator can... The feeding device feeds the pipe between the two drive rollers 12 on the top surface of the machine base 11. At this time, the linkage rod 53 is located at the center of the pipe. The operator can simultaneously open several drive electric push rods 63. When the drive electric push rods 63 extend, they can drive the remaining follow-up telescopic rods 64 to extend through the mounting base 65 and the connecting telescopic rod 66. This allows several abutment blocks 67 arranged in a ring array to move synchronously, so that the abutment blocks 67 can support the inner wall of the pipe. The cutting position can be located between several abutment blocks 67 on both sides to ensure the stability of the pipe during cutting, avoid deviation when the pipe diameter is large and the support is insufficient, and ensure the accuracy of cutting.

[0025] Reference Figure 6-9 As shown, a chip collection assembly is provided on the outer wall of the sliding sleeve 61 between the two sets of support structures. The chip collection assembly includes several arc-shaped retainers 71 fixedly installed between two opposing blocks 67. Each arc-shaped retainer 71 has an installation groove 72 at both ends. A connecting retainer 73 is slidably installed between two adjacent installation grooves 72 and is fixedly connected to the block 67. A material receiving port 74 is provided on the inner wall of the connecting retainer 73. A material transfer hopper 75 corresponding to the material receiving port 74 is fixedly installed on the side of the connecting retainer 73. A material collection box 76 is provided at the end of the material transfer hopper 75. A material locking structure is provided on the inner side of the material collection box 76. The material locking structure includes a fixed rod 81 fixedly installed on the inner wall of the discharge end of the material transfer hopper 75, a guide rod 82 fixedly installed on the bottom surface of the fixed rod 81, a limit plate 83 fixedly installed on the bottom end of the guide rod 82, and a sealing plate 84 slidably fitted on the outer wall of the guide rod 82, with the side of the sealing plate 84 fitting against the inner wall of the material transfer hopper 75.

[0026] During the cutting process, the electric actuator 63 drives the telescopic rod 64 to extend, causing the connecting cover 73 to slide along the mounting groove 72 at the end of the arc-shaped cover 71. This causes the arc-shaped cover 71 and the connecting cover 73 to deform. Both are made of plastic material and can move quickly under the influence of the abutment 67. When the abutment 67 contacts the inner wall of the pipe, the outer walls of the arc-shaped cover 71 and the connecting cover 73 simultaneously contact the inner wall of the pipe. Because the positions of the arc-shaped cover 71 and the connecting cover 73 correspond to the cutting position, when the debris generated by the circular saw 24 splashes onto the inner side of the pipe... It can enter the inner side of the arc-shaped cover 71 and the connecting cover 73. With the rotation of the linkage rod 53 and the pipe, the debris can enter the collection box 76 through the receiving port 74 and the transfer hopper 75. When the receiving port 74 is facing upward, the limiting plate 83 slides out of the transfer hopper 75 under the action of gravity, and the debris can enter the collection box 76. When the receiving port 74 is facing downward, the limiting plate 83 slides along the guide rod 82 into the transfer hopper 75 under the action of gravity to block the transfer hopper 75 and prevent the debris from being discharged from the collection box 76, so that most of the debris can be collected for subsequent collection and processing by the staff.

[0027] Working Principle: In use, the operator first needs to adjust the device according to the diameter of the pipe to be cut. This adjustment requires opening the control electric actuator 22 and the linkage electric actuator 52 to extend or shorten them. When the control electric actuator 22 is open, it can drive the support plate 23 and the circular saw 24 to the appropriate height. When the linkage electric actuator 52 is open, it can drive the linkage rod 53 to move along the guide port 51, thereby adjusting the height of the linkage rod 53 to correspond to the center of the pipe. After adjusting the circular saw 24 and the linkage rod 53, the operator can then... The position of the sliding sleeves 61 on the linkage rod 53 is adjusted according to the cutting situation so that the position of the sliding sleeves 61 corresponds to the cutting part of the pipe. During adjustment, the threaded sleeve 62 can be rotated. The threaded sleeve 62 is screwed to the linkage rod 53 and rotatably connected to the sliding sleeve 61. The sliding sleeve 61 and the linkage rod 53 are slidably connected through the sliding groove and the slider. Therefore, when the threaded sleeve 62 rotates, it can drive the sliding sleeve 61 to slide along the linkage rod 53 through the sliding groove and the slider, thereby realizing the adjustment of the position of the sliding sleeve 61. After the adjustment is completed, the operator can use the feeding device to feed the pipe between the two drive rollers 12 on the top surface of the machine base 11. At this time, the linkage rod 53 is located at the center of the pipe. The operator can simultaneously open several drive electric actuators 63. When the drive electric actuators 63 extend, they can drive the remaining follower telescopic rods 64 to extend through the mounting base 65 and the connecting telescopic rod 66. This allows several abutment blocks 67 arranged in a ring array to move synchronously, so that the abutment blocks 67 can support the inner wall of the pipe. The cutting position can be located between several abutment blocks 67 on both sides to ensure the stability of the pipe during cutting and avoid deviations when the pipe diameter is large and the support is insufficient. The precision of the cutting is ensured. Subsequently, the drive roller 12 and drive base 21 can be activated. When the drive roller 12 is activated, it can drive the pipe to rotate. During the rotation of the pipe, the drive base 21 moves along the guide groove 13, which drives the control electric push rod 22, the support plate 23 and the cutting circular saw 24 to move. When the cutting circular saw 24 moves to the cutting point, the control electric push rod 22 shortens and the cutting circular saw 24 is activated. The pipe can be cut by the circular saw blade, ensuring that the pipe can be cut precisely by the circular saw. With the cooperation of the drive base 21 and the control electric push rod 22, the cutting circular saw 24 can cut the pipe to a fixed length with precision. The working principle and connection method of the drive roller 12 and the drive base 21 are existing mature technologies, and will not be described in detail here. During the cutting process, as the electric push rod 22 drives the support plate 23 and the cutting circular saw 24 to move downwards and approach the pipe, the support ball 44 on the bottom surface of the circular saw cover 31 on the outer side of the circular saw blade can first contact the pipe. As the circular saw cover 31 moves downwards, several baffles 42 can slide along the slot 41 a different distance according to their contact with the pipe. The baffles 42 contact the outer wall of the pipe through the support ball 44 in the end-mounted ball groove 43, allowing the pipe to rotate normally. This ensures that when the circular saw blade is cutting, several baffles 42 can be located on the outside of the circular saw blade at the cutting point, avoiding the splashing of debris during the cutting process. At the same time, the dust pump 33 is turned on during the cutting process. The dust pump 33 can remove the debris generated inside the circular saw cover 31 through the dust suction pipe 34 and the dust suction shell 32, and discharge it through the discharge pipe. During the cutting process, the electric actuator 63 drives the telescopic rod 64 to extend, causing the connecting cover 73 to slide along the mounting groove 72 at the end of the arc-shaped cover 71. This causes the arc-shaped cover 71 and the connecting cover 73 to deform. Both are made of plastic material and can move quickly under the influence of the abutment 67. When the abutment 67 contacts the inner wall of the pipe, the outer walls of the arc-shaped cover 71 and the connecting cover 73 simultaneously contact the inner wall of the pipe. Because the positions of the arc-shaped cover 71 and the connecting cover 73 correspond to the cutting position, when the debris generated by the circular saw 24 splashes onto the inner side of the pipe... It can enter the inner side of the arc-shaped cover 71 and the connecting cover 73. With the rotation of the linkage rod 53 and the pipe, the debris can enter the collection box 76 through the receiving port 74 and the transfer hopper 75. When the receiving port 74 is facing upward, the limiting plate 83 slides out of the transfer hopper 75 under the action of gravity, and the debris can enter the collection box 76. When the receiving port 74 is facing downward, the limiting plate 83 slides along the guide rod 82 into the transfer hopper 75 under the action of gravity to block the transfer hopper 75 and prevent the debris from being discharged from the collection box 76, so that most of the debris can be collected for subsequent collection and processing by the staff.

[0028] The technical scope of this invention is not limited to the content described above.
