Description

Technical Field

[0001] This invention relates to the field of hose cutting technology, specifically to a drainage tube processing and cutting device. Background Technology

[0002] Drainage tubes are indispensable medical devices in the medical field, widely used in surgical procedures, trauma treatment, and intensive care. They are mainly used to drain accumulated fluid, blood, and pus from the body, ensuring postoperative recovery and reducing the risk of infection. Currently, medical drainage tubes are mostly made of polymer materials with good biocompatibility, flexibility, and a certain strength, such as silicone, polyvinyl chloride (PVC), and polyurethane (PU). Drainage tubes made of these materials are continuous strips. In practical applications, they need to be cut into finished drainage tubes of different lengths according to clinical needs. Therefore, cutting is one of the key processes in the production of drainage tubes. In existing technologies, drainage tube cutting mainly uses traditional blade cutting equipment, ultrasonic cutting equipment, or laser cutting equipment. Among them, blade cutting equipment has become the mainstream choice for small and medium-sized production enterprises due to its simple structure and low cost. Its working method is mostly to send the continuous tube to the cutting station through a conveying mechanism, and the drive mechanism drives the blade to move up and down to cut the tube. Some equipment will set a simple positioning clamp at the cutting station to help fix the tube and improve cutting stability.

[0003] However, due to the high flexibility and elasticity of medical drainage tubes, there are many technical problems when processing them using existing cutting equipment, which seriously affect product quality and production efficiency. On the one hand, the tube is prone to collapse and deformation due to its own elasticity during the cutting process, resulting in uneven cuts, burrs, or oblique cuts, which cannot meet the high precision requirements of medical drainage tubes and may even affect the safety of clinical use due to irregular cuts. On the other hand, existing equipment lacks effective pressure holding and cooling mechanisms. The friction between the blade and the tube during cutting generates high temperatures, which can easily cause the tube to melt and stick to the blade surface. This not only accelerates blade wear and shortens its service life but also further damages the integrity of the cut. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a drainage tube processing and cutting device. This invention uses a drive roller to move the pressure strip on the outer wall of the tube, which pushes the liquid-filled tube from back to front. This allows for both cyclical compression of the tube to maintain pressure and forward transport of the tube. Furthermore, during the tube cutting process, the bulging tube improves the integrity and uniformity of the cut. The liquid inside the tube also serves as a coolant for the blades and a detector for tube damage.

[0016] 3. This invention provides a water storage tank at the bottom of the blade groove, which, together with the coolant flowing out of the pipe, allows the blade to enter the water storage tank and come into timely contact with the coolant after cutting. This further cools the blade before it returns to its original position, thus preventing the blade from softening at high temperatures and sticking to the pipe. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 9 As shown, the present invention includes the following embodiments: Example 1: A drainage tube processing and cutting device includes a chassis 1 and a machine groove 11 extending through the upper surface of the chassis 1; a cutting table 2 is fixedly connected inside the machine groove 11; a discharge hopper 12 is fixedly connected to the front end of the machine groove 11; side plates 3 are fixedly connected to the upper surface of the cutting table 2 near the discharge hopper 12; side plates 4 are provided inside the side plates 3; one side plate 4 is rotatably connected to one end of a drive roller 5; an upper motor 41 is embedded inside the other side plate 4; the output end of the upper motor 41 is fixedly connected to the other end of the drive roller 5; a central groove 51 is provided in the center of the drive roller 5; stepped grooves 52 communicating with the central groove 51 are evenly provided on the arc-shaped outer wall of the drive roller 5; a cutter holder 53 protruding from the central groove 51 is slidably connected to one inner end of the stepped groove 52; the cutter holder 53 is connected to the stepped groove 52 by a cutter spring 54. The wall; the outer end of the stepped groove 52 is slidably connected to the blade 55 fixed to the blade holder 53; the central groove 51 is through to the left; the left end of the central groove 51 is provided with an inclined plate 61; the left side of the inclined plate 61 is connected to the inner side of the side block 4 through a micro electric push rod 6; the right side of the inclined plate 61 can squeeze the lowermost blade holder 53 to move outward along the stepped groove 52; the arc-shaped outer wall of the drive roller 5 is provided with a pressure tube groove 56 that is evenly offset from the stepped groove 52; the pressure tube groove 56 is slidably connected to a pressure tube strip 57; the pressure tube strip 57 is connected to the bottom of the pressure tube groove 56 through a pressure tube spring 58; the upper surface of the cutting table 2 is equipped with a tooling table 23 with tooling holes 22 at intervals by bolts 21 at the rear position; the tube 24 passes from back to front through the tooling hole 22, between the drive roller 5 and the cutting table 2; the end of the tube 24 away from the cut is connected to liquid.

[0022] In this embodiment, the pipe 24 is wound around the I-beam spool 7; a square hole 71 is provided through the center of the I-beam spool 7; a liquid pump 72 is provided below the I-beam spool 7; a pump frame 73 is fixedly connected to the top of the liquid pump 72; a frame hole 74 is provided through the left and right sides of the pump frame 73; the frame hole 74 is rotatably and sealingly connected to a dumbbell-shaped frame wheel 75; the left end of the frame wheel 75 is driven by an auxiliary motor 76; a square rod 77 is fixedly connected to the right end of the frame wheel 75; the square rod 77 and the I-beam spool... The hole at the center of the 7 is sealed; the right end of the square rod 77 is threaded to a limiting bolt 78; the outer wall of the frame wheel 75 and the inner wall of the frame hole 74 form a rotation gap 751; one end of the rotation gap 751 is connected to the liquid pump 72 through the first liquid hole 752; the outer wall of the I-beam wheel 7 is provided with an L-shaped connector 79; the L-shaped connector 79 is connected to the rotation gap 751 through the second liquid hole 753; one end of the pipe 24 is connected to the L-shaped connector 79 through a buckle 791.

[0023] First, the equipment is debugged and the pipe 24 is installed. This step is the foundation for ensuring the accurate and stable operation of subsequent cutting work and must be carried out step by step in strict accordance with the operating specifications: First, the drainage pipe 24 to be processed is neatly wound around the I-beam spool 7, ensuring that the pipe 24 is tightly wound, without wrinkles or damage. The I-beam spool 7 adopts an I-beam structure design, and its center is specially set with a square hole 71. The size of the square hole 71 is adapted to the cross-sectional size of the square rod 77, which is used to achieve precise matching and power transmission between the I-beam spool 7 and the square rod 77. Second, the I-beam spool 7 with the wound pipe 24 is smoothly placed on the outer wall of the square rod 77. During the placement process, it is necessary to operate slowly to avoid the pipe 24 being pulled or scratched. At the same time, the second liquid hole 753 inside the I-beam spool 7 is precisely aligned with the corresponding second liquid hole 753 on the square rod 77 to ensure that the liquid path can be smoothly connected and to avoid liquid leakage problems in the future. Third, after the I-beam wheel 7 is in place, tighten the limiting bolt 78 at the right end of the square rod 77. The limiting bolt 78 axially limits the I-beam wheel 7, completely preventing it from falling off the outer wall of the square rod 77 during rotation, ensuring safe operation of the equipment. Fourth, connect the pipe 24 to the liquid circuit. Securely connect one end of the pipe 24 to the L-shaped connector 79 on the outer wall of the I-beam wheel 7 using a special clip 791. The clip 791 must be tightened to ensure a good seal at the connection, preventing liquid leakage and achieving stable connection between the pipe 24 and the L-shaped connector 79, preparing for subsequent liquid flow into the pipe 24. Fifth, insert the pipe 24 and complete its positioning. Slowly insert the other end of the pipe 24 from back to front through the I-beam wheel 7. During the insertion process, the tooling holes 22 of the mounting platform 23 must be ensured to prevent the pipe 24 from twisting or bending. Then, the pipe 24 continues to pass through the gap between the drive roller 5 and the cutting table 2. The position of the pipe 24 is adjusted so that the pipe 24 is aligned with the center of the drive roller 5 and the cutting table 2. Then, the tooling platform 23 with tooling holes 22 is installed at intervals on the upper surface of the cutting table 2 using bolts 21. The bolts 21 must be tightened firmly to prevent the tooling platform 23 from shaking during equipment operation. At the same time, it is ensured that each pipe 24 is embedded in a corresponding tooling hole 22. By utilizing the characteristic that the inner diameter of the tooling hole 22 is adapted to the diameter of the pipe 24, the pipe 24 can be accurately positioned, avoiding the pipe 24 from shifting during conveying and cutting, and ensuring the accuracy of the cutting dimensions.

[0024] After the pipe 24 is installed, a comprehensive inspection of the equipment is required to confirm that all components are securely connected, there are no leaks in the liquid circuit, and the pipe 24 is accurately positioned. Then, the equipment is started and the liquid pump 72 is started. After the liquid pump 72 starts, it delivers liquid (the appropriate cooling and lubricating fluid can be selected according to the material of the pipe 24) through the first liquid hole 752 to the rotation gap 751 between the support wheel 75 and the pump frame 73 at the preset pressure. The rotation gap 751 adopts a sealing design, which can effectively prevent liquid leakage and does not affect the normal rotation of the support wheel 75. After the liquid is evenly distributed in the rotation gap 751, it smoothly enters the L-shaped connector 79 through the second liquid hole 753, and then is delivered to the inside of the pipe 24 along the channel of the L-shaped connector 79. The liquid is continuously delivered until the inside of the pipe 24 is completely filled. At this time, the pipe 24 is in a slightly bulging state due to the filling of the internal liquid, which lays the foundation for subsequent precise cutting.

[0025] Meanwhile, the pressing strip 57 naturally extends out of the pressing groove 56 under the elastic force of the pressing spring 58, and its extension height is just enough to make close contact with the outer wall of the pipe 24. Then, the upper motor 41 is started, and the upper motor 41 runs smoothly at the preset speed. Its output end is fixedly connected to one end of the drive roller 5 through a coupling, thereby driving the drive roller 5 to rotate synchronously. During the rotation of the drive roller 5, the multiple pressing strips 57 on its arc-shaped outer wall make circular motions, cyclically squeezing and pushing the outer wall of the pipe 24. Since the number of pressing strips 57 on the axial direction of the drive roller 5 is set to multiple, and the distance between two adjacent pressing strips 57 is small, at least one pressing strip is pressed during the entire rotation of the drive roller 5. The pressure bar 57 can always press the end of the tube 24, effectively blocking the overflow channel of the liquid inside the tube 24, avoiding large-scale liquid leakage that would cause waste and equipment pollution. At the same time, the squeezing and pushing action of the pressure bar 57 can generate a continuous driving force, driving the tube 24 to be transported smoothly and at a constant speed from back to front. The transport speed can be adjusted according to the cutting requirements to ensure that the tube 24 is transported without jamming or deviation. During the rotation of the upper motor 41, the auxiliary motor 76 will also rotate adaptively. The auxiliary motor 76 will drive the frame wheel 75, the square rod 77 and the I-beam wheel 7 to rotate, realizing the unwinding of the tube 24. The pressure bar 57 will retract into the pressure groove 56 as the drive roller 5 rotates, overcoming the pressure spring 58.

[0026] During equipment operation, the conveying length of the pipe 24 is monitored in real time by the equipment's built-in positioning sensor. When the pipe 24 is conveyed to the preset cutting length, the positioning sensor sends a signal to the equipment control system. The control system immediately issues a command to control the miniature electric push rod 6 to extend at a preset speed. The telescopic end of the miniature electric push rod 6 is fixedly connected to the left side of the inclined plate 61. During its extension, it drives the inclined plate 61 to move synchronously to the right. The inclined plate 61 adopts an inclined structure design, and its right inclined surface only contacts the lowermost cutter holder 53. As the inclined plate 61 continues to move to the right, the inclined plate 61 generates a uniform squeezing force on the lowest cutter holder 53. Under the action of the squeezing force, the cutter holder 53 overcomes the elastic force of the cutter spring 54 and slowly slides outward along the guide direction of the stepped groove 52. Since the cutter holder 53 is fixedly connected to the blade 55, the blade 55 moves outward synchronously while the cutter holder 53 slides, until the blade 55 is fully extended from the outer end of the stepped groove 52. The extension length can meet the cutting requirements of the pipe 24, and the cutting edge of the blade 55 is aligned with the cutting position of the pipe 24. At this time, the pipe 24 is in a bulging state because it is filled with liquid. This bulging state can keep the cross-section of the pipe 24 regular and avoid problems such as collapse and deformation during cutting. As the blade 55 moves downward, it can quickly and accurately cut the bulging pipe 24. During the cutting process, the liquid flowing out of the pipe 24 can directly wash the surface of the blade 55 and cool the blade 55 in real time, effectively reducing the cutting temperature of the blade 55 and preventing the blade 55 from softening and wearing due to high temperature. At the same time, it prevents the blade 55 from sticking to the cut of the pipe 24 under high temperature, ensuring a smooth cutting process and avoiding defects such as burrs and adhesion. After cutting, the equipment control system immediately issues a command to shorten the micro electric push rod 6. During the shortening process, the micro electric push rod 6 drives the inclined plate 61 to move synchronously to the left, gradually moving away from the lowermost cutter holder 53. At this time, the compressive force on the cutter holder 53 disappears. Under the elastic force of the cutter spring 54, the cutter holder 53 slowly slides inward along the guide direction of the stepped groove 52, simultaneously driving the blade 55 to retract synchronously into the stepped groove 52. This prevents the blade 55 from colliding with the pipe 24 or other parts of the equipment in the non-cutting state, causing damage to the blade 55 or scratches to the pipe 24. During the retraction of the blade 55, the stepped groove 52... The groove can effectively remove the remaining pipe debris and stains from the surface of the blade 55 (the cross-sectional specifications of the blade 55 are adapted to the specifications of the outer end of the stepped groove 52), ensuring that the surface of the blade 55 is clean and ready for the next cut, avoiding the impact of debris on the cutting accuracy and the service life of the blade 55; after the blade holder 53 and the blade 55 are reset, the drive roller 5 is started and rotates at the preset speed. The pressure strip 57 on its outer wall continuously squeezes and pushes the outer wall of the remaining pipe 24, driving the remaining pipe 24 to continue to be smoothly conveyed forward and enter the next round of cutting cycle. The whole cutting process is continuous and efficient, without the need for manual intervention.

[0027] Because multiple cutter holders 53 and blades 55 are evenly arranged on the arc-shaped outer wall of the drive roller 5, and the multiple cutter holders 53 are evenly staggered with the stepped groove 52 and the pressing groove 56, multiple blades 55 will be used intermittently during the rotation of the drive roller 5. Each blade 55 has sufficient time to cool and reset, which effectively reduces the usage frequency of a single blade 55, further achieving the purpose of cooling and preventing sticking of the blades 55 and extending the service life of the blades 55. At the same time, the cut drainage pipe falls smoothly into the discharge hopper 12 at the front end of the machine slot 11 under its own gravity and the pushing action of the pressing strip 57. The discharge hopper 12 adopts an inclined structure design, which can guide the drainage pipe to fall quickly and orderly, and finally fall into the pre-set collection bucket below, which is convenient for subsequent sorting, inspection and packaging of the cut drainage pipe.

[0028] Throughout the cutting process, operators must remain on-site, constantly monitoring the operating status of the pipe 24 and the equipment's operation. This is crucial for ensuring product quality and safe equipment operation. Since the pipe 24 will bulge uniformly once filled with liquid, its surface should remain flat without any abnormal protrusions or depressions. If the operator observes liquid overflowing from a certain location on the pipe 24, it indicates a quality problem such as damage or pinholes. The machine must be stopped immediately, and the damaged pipe 24 must be inspected and replaced to prevent substandard pipes from entering subsequent processes and effectively ensure the quality of the final product. Simultaneously, the rotation of the drive roller 5, the clamping force of the pressure strip 57, the cutting effect of the blade 55, and the sealing of the liquid path must be observed. If abnormal rotation of the drive roller 5, insufficient clamping force of the pressure strip 57, burrs on the blade 55, or leaks in the liquid path are detected, the machine must be stopped immediately for debugging and repair. This ensures the equipment is always in normal working order, preventing equipment malfunctions from affecting cutting efficiency and product quality, while also ensuring the personal safety of the operators.

[0029] The present invention uses a drive roller 5 to drive the outer wall pressure strip 57 to push the liquid-filled pipe 24 from back to front, thereby cyclically pressing the pipe 24 to maintain pressure and controlling the forward conveying of the pipe 24. In the process of cutting the pipe 24, the bulging of the pipe 24 can improve the integrity and uniformity of the cut. The liquid inside the pipe 24 can also act as a cooling blade 55 and a detector for whether the pipe 24 is damaged.

[0030] Example 2: The side plate 3 is provided with a side groove 31 running through the left and right sides; the side groove 31 is slidably connected to the side block 4; the upper end of the side block 4 is rotatably connected to the screw 32; the upper end of the screw 32 passes through the upper end of the side plate 3 and is threadedly connected to the side plate 3; the upper end of the screw 32 is fixedly connected to the handle 33.

[0031] During the equipment debugging phase and before the installation of the tube 24, the gap between the drive roller 5 and the cutting table 2 needs to be adjusted according to the actual diameter of the medical drainage tube 24 to be processed to match the specifications of the tube 24. The operator holds the handles 33 on both side plates 3 with both hands, maintaining even force and consistent rotation speed, and rotates the two screws 32 synchronously. Because the screws 32 are threaded to the side plates 3 and the side blocks 4 are slidably connected to the side grooves 31 of the side plates 3, and the lower end of the side blocks 4 is rotatably connected to the screws 32, the rotation of the screws 32 will not drive the side blocks 4 to rotate synchronously, but will only generate axial driving force, which will drive the side blocks 4 to slide smoothly up and down along the side grooves 31, thereby synchronously driving the drive roller 5, the upper motor 41 and the inclined plate 61 connected thereto, and the miniature electric push rod. 6. The tool holder 53, blade 55 and other components are raised and lowered as a whole; the operator observes the gap size in real time and can use a ruler to assist in measurement until the gap size is slightly larger than the diameter of the pipe 24 to be processed (leaving a reasonable margin to ensure that the pipe 24 passes through smoothly and the pressure strip 57 can effectively tighten). At this time, the thread structure of the screw 32 and the side plate 3 achieves self-locking, fixing the position of the side block 4 and the drive roller 5, and completing the gap adjustment; after the gap adjustment is completed, the pipe 24 winding, the I-beam wheel 7 installation, the pipe 24 insertion and positioning, the hydraulic circuit connection and other subsequent operations are completed according to the original process of the equipment; if it is necessary to replace the pipe 24 with a different diameter later, repeat the above operation, and simultaneously rotate the handle 33 to adjust the screw 32 to adjust the gap to adapt to the cutting requirements of the new specification pipe 24.

[0032] The present invention uses the side groove 31 on the side plate 3 to slide with the side block 4, and the screw 32 and handle 33 to drive the drive roller 5 and related components to rise and fall synchronously, thereby adjusting the gap between the drive roller 5 and the cutting table 2, so as to achieve the effect of adapting to the cutting of medical drainage tubes 24 of different diameters and improving the versatility of the equipment.

[0033] Example 3: A support groove 25 is provided on the front part of the upper surface of the cutting table 2; two support rollers 9 are rotatably connected in the support groove 25; a support belt 91 is driven to the outer wall of the support rollers 9; support rods 92 are rotatably connected to the upper and lower parts of the inner side of the support belt 91; the support rods 92 are rotatably connected to the support groove 25; one of the support rollers 9 is driven by a main motor 93.

[0034] In this embodiment, the outer wall of the support roller 9 is provided with teeth 94; the inner wall of the support belt 91 is provided with grooves 95; the grooves 95 and the teeth 94 correspond to each other and mesh.

[0035] After adjusting the gap between the drive roller 5 and the cutting table 2, installing the pipe 24, and connecting the hydraulic circuit, the main motor 93 is started synchronously when the equipment is started. The main motor 93 drives one of the support rollers 9 in the support groove 25 to rotate. Since the outer wall of the support roller 9 is provided with teeth 94, and the inner wall of the support belt 91 is provided with grooves 95 that mesh with the teeth 94, the meshing transmission between the teeth 94 and the grooves 95 can ensure that the support roller 9 rotates stably and drives the support belt 91 to move synchronously, avoiding slippage between the support belt 91 and the support roller 9, and ensuring the stability and synchronicity of the transmission. During the movement of the support belt 91, the support rods 92 at the upper and lower positions on its inner side roll synchronously. The support rods 92 are rotatably connected to the support groove 25, which can support the support. The support belt 91 provides effective support, preventing it from collapsing or deforming under the pressure of the pipe 24 and during its own movement, ensuring that the support belt 91 remains flat at all times. The pipe 24 is conveyed from back to front under the squeezing and pushing action of the pipe strip 57 on the outer wall of the drive roller 5. At this time, the lower surface of the pipe 24 is in close contact with the support belt 91. Since the support belt 91 can move synchronously with the rotation of the drive roller 5, and the two move in the same direction, no friction is formed between the pipe 24 and the support belt 91. This replaces the static friction between the original cutting table 2 and the pipe 24, effectively avoiding the problems of poor conveying and jamming of the pipe 24 caused by static friction, as well as scratches on the surface of the pipe 24, ensuring that the conveying process of the pipe 24 is stable and smooth.

[0036] Meanwhile, the width of the support belt 91 in the front-to-back direction is greater than the distance between two adjacent pressure strips 57 on the drive roller 5. When the drive roller 5 rotates and drives the two adjacent pressure strips 57 to press the pipe 24 simultaneously, the two pressure strips 57 can press the pipe 24 onto the upper surface of the support belt 91 in a synchronized manner, further improving the stability of the pipe 24 during conveying. Throughout the entire cutting cycle, the support belt 91 remains in motion, and in conjunction with the pushing action of the pressure strips 57, it provides stable support and smooth conveying assistance for the pipe 24 throughout the process until the pipe 24 is cut and falls into the discharge hopper 12. This invention uses the support belt 91 to drive the pipe 24 by rotating with the drive roller 5, replacing the static friction between the cutting table 2 and the pipe 24, thereby effectively avoiding the problems of poor conveying, jamming, and surface scratches of the pipe 24 caused by static friction, achieving the effect of protecting the surface integrity of the pipe 24 and improving conveying efficiency.

[0037] Example 4: The outer wall of the support belt 91 is provided with a groove 96 corresponding to the blade 55; the blade 55 can enter the corresponding groove 96.

[0038] In this embodiment, a water storage tank 97 is provided at one end of the knife groove 96 near the inner wall of the support belt 91; the water storage tank 97 and the knife groove 96 pass through the support belt 91 on both sides; the edge of the support belt 91 is in contact with the inner wall of the support groove 25.

[0039] After the equipment is started and the support belt 91 moves synchronously with the support roller 9, the groove 96 on the outer wall of the support belt 91 precisely corresponds to the position of the blade 55 on the drive roller 5, ensuring that the blade 55 can smoothly enter the corresponding groove 96 when cutting. When the equipment reaches the cutting stage, the micro electric push rod 6 extends and drives the inclined plate 61 to squeeze the blade holder 53. The blade holder 53 drives the blade 55 to extend outward along the stepped groove 52. When cutting the bulging pipe 24, the blade 55 will simultaneously extend into the corresponding groove 96 of the support belt 91. The groove 96 provides cutting clearance space for the blade 55, avoiding collision and wear between the blade 55 and the support belt 91 during cutting. At the same time, it ensures that the blade 55 can completely cut the pipe 24, preventing incomplete cutting and pipe 24 adhesion, and ensuring the integrity and regularity of the cut. Since the inside of the pipe 24 is filled with liquid, during the cutting process, the coolant (or water) flowing out of the pipe 24 will flow into the groove 96 near the inner wall of the support belt 91. In the water storage tank 97 at one end, both the water storage tank 97 and the knife groove 96 are connected to the support belt 91 on both sides. The support belt 91 is made of elastic material with a certain thickness. The edge of the support belt 91 is in contact with the inner wall of the support groove 25. The core advantage of this design is to prevent the liquid in the water storage tank 97 from flowing out from the edge of the support belt 91. After the blade 55 enters the water storage tank 97, there is enough water to further cool the blade 55. After the blade 55 is cooled, it is removed from the water storage tank 97 and the knife groove 96 and has completed cooling, further preventing adhesion to the cut of the pipe 24. As the support roller 9 drives the support belt 91 to move continuously and perform arc-shaped rotation, the openings of the water storage tank 97 and the knife groove 96 will always be facing downwards. Especially when the support belt 91 moves to the support roller 9 at the front position, the support belt 91 will undergo slight deformation due to the arc-shaped rotation. Its own elasticity will cause the knife groove 96 to open slightly, and the coolant in the water storage tank 97 and the knife groove 96 will flow out from the downward-facing opening.

[0040] The present invention provides a water storage tank 97 at the bottom of the blade groove 96, which, together with the coolant flowing out of the pipe 24, allows the blade 55 to enter the water storage tank 97 and come into timely contact with the coolant after cutting. This allows the blade 55 to be further cooled before returning to its original position, thus further preventing the blade 55 from softening at high temperature and sticking to the pipe 24.

[0041] Example 5: The pressure strip 57 is composed of multiple pressure blocks 571; the pressure blocks 571 are slidably connected in the pressure groove 56; the cross-sectional shape of the pressure strip 57 is convex; the cross-sectional shape of the pressure groove 56 is concave; two adjacent pressure blocks 571 are in contact.

[0042] The pressing strip 57 is composed of multiple pressing blocks 571, which are slidably connected in the pressing groove 56. Adjacent pressing blocks 571 are in contact with each other, ensuring that the pressing strip 57 can flexibly adapt to the shape of the pipe 24 and the movement trajectory of the pressing groove 56. After the equipment is started, the pressing strip 57 extends from the pressing groove 56 under the elastic force of the pressing spring 58. When the drive roller 5 rotates and moves the pressing strip 57 to contact the pipe 24, the pressing blocks 571 at the corresponding positions of the pipe 24 will tightly adhere to the outer wall of the pipe 24, generating a uniform pressing force on the pipe 24. The pressure is maintained on the pipe 24 to prevent leakage of coolant inside the pipe 24. The pressure block 571, which does not contact the pipe 24, makes active contact with the surface of the support belt 91. On the one hand, it can assist the synchronous transmission of the support belt 91, and on the other hand, it can limit the pipe 24 in the left and right directions to prevent the pipe 24 from deviating in the left and right directions during transportation and ensure the accurate transportation direction of the pipe 24. The convex cross section pressure bar 57 and the concave cross section pressure groove 56 cooperate with each other (simplified setting in the figure) to effectively prevent the pressure bar 57 from falling out of the pressure groove 56 and ensure the stable operation of the equipment.

[0043] Example 6: The distance between two adjacent pressure strips 57 is less than the front-to-back length of the upper surface of the support strip 91.
