Description

Technical Field

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

[0002] Chinese patent CN202210976184X discloses an automated hose cutting device and method. This device is suitable for cutting metal hoses formed by winding stainless steel. A key step in this product is cutting the stainless steel hose. A motor drives a high-speed rotating blade, which cuts into the metal hose from top to bottom to a certain depth, severing the upper stainless steel strip. The hose is then separated by rotating it. The device uses a conveyor belt for feeding, delivering a set length before cutting. Because metal hoses are inherently elastic, they tend to contract during transport, but the degree of contraction is somewhat random. Specifically, less resistance during transport results in less contraction, and greater resistance results in greater contraction, leading to variations in the length of the cut metal hoses.

[0003] Chinese patent CN2020103523124 discloses an automated cutting machine for stainless steel flexible metal hoses. This equipment is specifically designed for cutting stainless steel wound steel strip hoses and also uses an abrasive wheel to cut the metal hose. The machine employs a guide rail and a cylinder for pulling; a fixed cylinder stroke is set to pull a standard length of metal hose before cutting. However, due to the varying elasticity of the metal hose and the different resistance during the pulling process, the degree of extension and retraction of the metal hose varies, resulting in differences in the actual length of the cut metal hose.

[0004] In addition, if the metal hose is taut during the process of the cylinder pulling it up, the metal hose will jump at the moment of cutting the upper stainless steel strip, causing the grinding wheel blade to collide rapidly with the metal hose, resulting in abnormal wear of the grinding wheel blade and safety hazards. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a flexible hose cutting machine with a length control mechanism for a telescopic metal hose cutting machine that allows for convenient control of the cutting length.

This machine is used to cut metal flexible hoses, specifically telescopic metal flexible hoses made of wound stainless steel strips, commonly used as the outer hoses of bathroom showerheads. The pre-detection mechanism detects the hose's condition; the conveying mechanism grips and conveys the metal hose; the cutting mechanism cuts the metal hose; the length control mechanism controls the hose length in a single cut; and the stripping mechanism is a rotary stripping mechanism used to separate the metal hose at the cutting point of the cutting mechanism.

[0015] Preferably, it further includes a pre-detection mechanism, which is disposed in front of the conveying mechanism and is used to detect the state of the hose; the pre-detection mechanism includes a detection bracket, a trigger ring assembly, a pulley assembly, and a first sensor; the detection bracket is mounted on one side of the machine body; the trigger ring assembly is disposed below the detection bracket and can move along a set direction under the action of external force; the trigger ring assembly includes a ring body with a first through hole in the middle of the ring body for the metal hose to pass through; the pulley assembly is used to guide the metal hose so that the metal hose is conveyed along a set trajectory; the first sensor is disposed on the detection bracket, with the detection end of the first sensor facing the trigger ring assembly; when the trigger ring assembly moves to a set position, the first sensor sends a detection signal to the controller.

[0020] A second sensor is provided on the side of the detection bracket, with the detection end of the second sensor facing the first through hole; when the hose passes through the first through hole, the second sensor sends a detection signal to the controller.

[0021] The outstanding and beneficial technical effects of this invention compared to the prior art are:

[0022] 1. The fixed reference mechanism of the present invention transports the metal hose to the movable reference mechanism. The movable reference mechanism controls the tension of the metal hose through the linkage of the first-stage sliding component and the second-stage sliding component, and further controls the distance between the cutting point and the clamping point of the metal hose, thereby ensuring that the length of the hose cut each time is the same. The mechanism has the characteristics of simple structure and high working efficiency.

[0023] 2. In this invention, the clamping component is installed on the front side of the rotating component and rotates synchronously with the rotating component. The rotating component is rotatably installed on the frame. The driving component installed on the upper side of the frame drives the rotating component to rotate, which in turn drives the clamping component to rotate. A through hole is provided through the rotating component and the upper middle part of the frame. The hose enters the through hole and is clamped by the clamping component. After the cutting action is completed, the hose is rotated by the rotating component to perform the unloading operation and is transported to the next mechanism of the pipe cutting machine. This mechanism has a simple structure, is not prone to failure, and has low noise.

[0024] 3. The present invention forms a certain angle between the grinding wheel blade and the extension direction of the guide groove, so that when the grinding wheel blade cuts the metal hose, the plane on which the grinding wheel blade is located is not parallel to the extension direction of the metal hose. The grinding wheel blade actually needs to perform cutting work on an elliptical arc surface. The arc surface can effectively disperse the pressure applied to the metal hose by the saw blade when cutting the metal hose, thereby reducing the deformation of the metal hose, making the cut more neat, and reducing the burrs generated after cutting.

[0025] 4. In this invention, both the upper conveying assembly and the inner side of the feeding conveyor belt of the upper conveying assembly are provided with adjusting rotating wheels. The position of the adjusting rotating wheels on the feeding bracket can be adjusted, thereby adjusting the tension of the feeding conveyor belt, reducing wear on the feeding conveyor belt, and preventing slippage between the feeding conveyor belt and the metal hose. This not only reduces wear on the feeding conveyor belt but also improves the working efficiency of the mechanism. In addition, a middle guide assembly is provided between the upper conveying assembly and the lower conveying assembly. The middle guide assembly guides the metal hose at its inlet and outlet ends, thereby reducing the probability of the metal hose getting stuck and further improving the working efficiency of the mechanism.

[0026] 5. The detection bracket of the present invention is equipped with a first sensor, a trigger ring assembly is provided below the detection bracket, and a pulley assembly for guiding the hose to be transported along a set trajectory is provided above the detection bracket. When the mechanism is working, the pulley assembly guides the hose to be transported. When the hose gets stuck, the pulley assembly continues to transport, the hose tightens and pushes the ring of the trigger ring assembly to move upward. When it moves to the set position, the first sensor detects the ring and sends a detection signal to the controller, causing the conveying mechanism of the machine to stop working and triggering an alarm. This allows for timely detection of machine malfunctions and avoids more serious damage to the machine. Attached Figure Description

Detailed Implementation

[0055] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figures 1-19 :

[0069] The movable mounting frame 209 is a flat plate structure. One end of the connecting rod 205 is fixedly installed in the middle. The two sides of the rod are symmetrically vertically provided with third waist-shaped holes 219. The feed bracket 201 is provided with through holes corresponding to the positions of the two third waist-shaped holes 219. By adjusting the position of the third waist-shaped holes 219 corresponding to the through holes, the height of the movable mounting frame 209 can be adjusted, and thus the height of the upper adjusting rotating wheel 222 can be adjusted.

[0070] Furthermore, the upper conveying assembly 202 also includes two upper pressure rollers 242, which are disposed on the lower side of the middle of the two upper rotating rollers 212. The upper pressure rollers 242 are rotatably mounted on the upper pressure roller mounting base 207.

The pressure roller mounting base... The upper two sides of the 207 extend forward and are installed on the feeding bracket 201. The feeding bracket 201 has two second waist-shaped holes 208 vertically arranged at the corresponding positions at both ends of the clamping wheel mounting seat 207. The upper two sides of the clamping wheel mounting seat 207 extend forward and pass through the second waist-shaped holes 208 and are installed on the movable mounting plate 2010. The upper feeding conveyor belt 232 is wrapped around the outside of the two upper rotating wheels 212, the upper adjusting rotating wheel 222 and the two upper clamping wheels 242.

[0071] Among them, the movable mounting plate 2010 is a flat plate structure, which can be installed on the feeding bracket 201 in a vertically movable manner. By adjusting the vertical movement of the movable mounting plate 2010, the clamping wheel mounting seat 207 is driven to move vertically within the second oblong hole 208, thereby adjusting the height of the upper clamping wheel 242, and thus adjusting the fit between the upper feeding conveyor belt 232 and the metal hose 1.

[0072] Furthermore, the lower conveying assembly 203 is disposed on the lower front of the feeding bracket 201. The lower conveying assembly 203 includes two lower rotating wheels 213, a lower adjusting rotating wheel 223, and a lower feeding conveyor belt 233. The two lower rotating wheels are symmetrically mounted on the feeding bracket 201, and the two lower rotating wheels 213 are symmetrically mounted on the feeding bracket 201. The line connecting the centers of the two lower rotating wheels 213 is parallel to the horizontal plane. The lower adjusting rotating wheel 223 is located on the lower side of the middle of the two lower rotating wheels 213. A connecting rod 205 is provided in the middle of the 3 section, and the lower adjusting rotating wheel 223 rotates around the connecting rod 205. A first waist-shaped hole 206 is vertically provided on the feeding bracket 201 corresponding to the position of the lower adjusting rotating wheel 223. A movable mounting frame 209 is installed on the back of the feeding bracket 201. The connecting rod 205 passes through the first waist-shaped hole 206 and is fixedly installed on the movable mounting frame 209. The movable mounting frame 209 moves up and down, thereby driving the lower adjusting rotating wheel 223 to adjust its position up and down, thereby achieving the purpose of adjusting the tension of the lower feeding conveyor belt 233.

[0073] Furthermore, the lower conveying assembly 203 also includes two lower pressing rollers 243. The two lower pressing rollers 243 are located on the upper side of the middle of the two lower rotating rollers 213. The lower pressing rollers 243 are rotatably mounted on the pressing roller mounting base 207 located at the lower part. The lower pressing rollers 243 are set inside the lower feeding conveyor belt 233 and are used to press the lower feeding conveyor belt 233 upward, so that the lower feeding conveyor belt 233 fits the metal hose 1 better.

[0074] The installation method and vertical adjustment method of the lower clamping wheel mounting base 207 are the same as those of the upper clamping wheel mounting base 207, so they will not be described in detail.

[0075] Furthermore, the middle guide assembly 204 features a slotted opening design, located between the upper conveying assembly 202 and the lower conveying assembly 203. It guides the metal hose 1 within a predetermined trajectory, preventing it from getting stuck and affecting the normal operation of the mechanism. The middle guide assembly 204 is divided into an inlet guide section 214, an outlet guide section 224, and a clearance hole 234. The inlet guide section 214 is formed on the front side of the middle guide assembly 204, with its input end connected to the output end of the third through hole. The outlet guide section 224 is formed on the rear side of the middle guide assembly 204, with its output end connected to the guide groove 432 of the cutting mechanism. The clearance hole 234 is formed in the middle guide section 204. In the middle of the middle guide assembly 204, between the inlet guide 214 and the outlet guide 224, the clearance hole 234 is an elongated structure. The upper feeding conveyor belt 232 contacts and clamps the upper side of the metal hose 1 corresponding to the clearance hole 234; the lower feeding conveyor belt 233 contacts and clamps the lower side of the metal hose 1 corresponding to the clearance hole 234. The inlet guide 214 of the middle guide assembly 204 guides the metal hose 1 into the middle guide assembly 204, through the clearance hole 234, and then out through the outlet guide 224. When the metal hose 1 passes through the clearance hole 234, it is clamped on both sides by the upper and lower feeding conveyor belts 232 and 233 and conveyed to the outlet guide 224.

[0076] Furthermore, a front detection unit is provided on the front side of the entry guide 214, which includes a detection bracket 10, a trigger ring assembly 101, a pulley assembly, and a first sensor 103. The detection bracket 10 has a flat plate structure, one end of which is fixed to the housing of the cutting machine. The trigger ring assembly 101 is provided on its lower side. The trigger ring assembly 101 can move upward under the action of external force. The trigger ring assembly 101 includes a ring body 111, and a first through hole is provided in the middle of the ring body 111 for the metal hose 1 to pass through. The pulley assembly is used to guide the metal hose 1 and transport the metal hose 1 to the entry guide 214. The first sensor 103 is installed on the detection bracket 10, with its detection end facing the trigger ring assembly 101. When the trigger ring assembly 101 is subjected to external force, the sensor detects the metal hose 103. When the force is applied and the material moves to the set position, the first sensor 103 sends a detection signal to the controller. The front-end detection unit is used to detect whether the hose is stuck during the front-end conveying process of the pipe cutter. When the conveying mechanism starts working, the stainless steel hose used as raw material is coiled into a ring. During the unfolding process of the stainless steel metal hose 1, due to its elasticity, it may get stuck. When the hose is stuck, the pulley assembly continues to convey, the hose tightens and pushes the ring body 111 of the trigger ring assembly 101 upward. When it reaches the set position, the first sensor 103 detects the ring body 111 and sends a detection signal to the controller, causing the conveying mechanism to stop working and triggering an alarm. This allows the operator to promptly detect the fault and make adjustments, preventing more serious damage to the pipe cutter. This mechanism is suitable for pre-detection during the conveying process of the metal hose 1.

[0077] Furthermore, a hose cutting mechanism is provided on the right side of the conveying mechanism. This cutting mechanism is used to cut the metal hose 1 to a certain length.

[0078] Furthermore, the cutting mechanism includes a base 40; a lifting mechanism 42 mounted on the base 40; and a tool assembly 41 mounted on the lifting mechanism 42 and used for cutting metal hoses. The lifting mechanism 42 can drive the tool assembly 41 to move up and down relative to the base 40. The tool assembly 41 includes a spindle 411 and a grinding wheel blade 412, with the spindle 411 driving the grinding wheel blade 412 to rotate.

[0079] When the grinding wheel blade 412 rotates, the lifting mechanism 42 moves the tool assembly 41 up and down, and makes the tool assembly 41 abut against the metal hose, thereby cutting the metal hose.

[0080] A hose support platform 43 is mounted on a base 40. The hose support platform 43 is provided with a guide groove 432 for constraining the metal hose, and the guide groove 432 is used to guide the metal hose to move in a set direction.

[0081] like Figure 17As shown, the acute angle α ranges from 30 to 60 degrees. If the acute angle α is too large or too small, it will be difficult to cut the metal flexible hose. As a preferred embodiment, the acute angle α is 45 degrees.

[0082] The cutting plane of the abrasive wheel blade 412 forms an acute angle α with the extension direction 437 of the guide groove 432. This ensures that when the abrasive wheel blade 412 cuts the metal hose, the plane of the abrasive wheel blade 412 is not parallel to the extension direction 437 of the metal hose. In other words, the surface 413 of the metal hose to be cut is an elliptical arc surface relative to the abrasive wheel blade 412. This arc surface disperses the pressure to both ends, effectively resisting the pressure exerted on the metal hose by the abrasive wheel blade 412 during cutting, reducing the deformation of the metal hose, ensuring a cleaner cut, and minimizing burrs after cutting.

[0083] After the metal hose is cut, since the grinding wheel blade 412 is actually cutting an elliptical arc surface, the straight distance between the two ends of the cut will be shorter along the length of the metal hose, reducing the burrs generated after cutting.

[0084] The common cutting method now is as follows Figure 18 As shown, the plane of the grinding wheel blade 412 is parallel to the extension direction 437 of the metal hose, and the surface 413 of the metal hose to be cut is a straight surface relative to the grinding wheel blade 412. This results in a longer cut, and the pressure applied by the grinding wheel blade 412 to the metal hose extends along the extension direction 437 of the metal hose. This makes it difficult for the metal hose to distribute the pressure applied by the grinding wheel blade 412, easily causing deformation of the metal hose during cutting, reducing the smoothness of the cut and the processing quality.

[0085] Furthermore, a clamping and positioning device 44 is provided on one side of the hose support platform 43. The clamping and positioning device 44 is used to fix the metal hose, thereby facilitating the cutting work of the grinding wheel blade 412.

[0086] The clamping and positioning device 44 includes a cylinder 441 and a clamping block 442. The clamping block 442 is located on the upper side of the hose support platform 43 and can be clamped onto the hose support platform 43 by the cylinder 441. The pressure applied to the clamping block 442 can be changed by adjusting the air pressure of the cylinder 441 during operation, so that the clamping block 442 presses against the metal hose with a lower pressure, ensuring that the metal hose is fixed without causing large deformation of the metal hose. This allows the grinding wheel blade 412 to leave a smooth and neat cut when cutting the metal hose, reducing the generation of burrs.

[0087] The lower surface of the clamping block 442 is provided with a recess 443, which cooperates with the guide groove 432 to clamp the metal hose. The recess 443 has a trapezoidal structure. When the clamping block 442 presses on the metal hose, a portion of the inclined surface on both sides of the trapezoidal recess 443 will abut against the side wall of the metal hose, achieving the purpose of clamping. If the recess 443 is arc-shaped, in order to achieve the purpose of clamping the metal hose, the recess 443 needs to match the size of the metal hose; otherwise, it will cause large deformation of the metal hose during the clamping process, which is not conducive to cutting the metal hose.

[0088] Furthermore, the guide groove 432 has an elongated upper hollow groove 433 inside, the length direction of which is consistent with the extension direction 437 of the guide groove 432. During the cutting of the metal hose, coolant needs to be continuously injected to reduce the high temperature generated by high-speed friction, inhibiting the deformation of the metal hose due to heat, thereby improving the accumulation of chips and burrs generated by friction on the working surface, and increasing the working efficiency and cutting quality during the cutting process.

[0089] Meanwhile, a large amount of debris is also generated during the cutting of the metal hose by the abrasive wheel blade 412. The upper hollow groove 433 is located directly below the metal hose when the abrasive wheel blade 412 is cutting it. The debris and used coolant generated during the cutting process can be discharged into the guide groove 432 through the upper hollow groove 433 to maintain the stability of the cutting operation.

[0090] Furthermore, the hose support platform 43 includes an inner support body 431 and an outer support body 434; the outer support body 434 is provided with an embedding groove 435 in the middle, and the inner support body 431 is embedded in the embedding groove 435 of the outer support body 434, and the inner support body 431 can be screwed onto the outer support body 434.

[0091] The guide groove 432 is provided on the inner support 431, and the outer support 434 is provided with a lower hollow groove 436. The lower hollow groove 436 corresponds to the upper hollow groove 433, so that the debris and coolant discharged through the upper hollow groove 433 continue to be discharged through the lower hollow groove 436 to the bottom of the hose support platform 43, thereby facilitating the collection of the discharged debris and coolant.

[0092] A detection sensor 45 is provided on one side of the outer support 434, with its detection end facing the guide groove 432, and is used to detect the metal hose in the guide groove 432. If the detection sensor 45 does not detect the metal hose, it indicates that the metal hose is stuck or there is another malfunction, and the lifting mechanism 42 and the cutter assembly 41 are controlled not to perform cutting operations.

[0093] Furthermore, the lifting mechanism 42 includes:

[0094] The slider 46 and the tool assembly 41 are mounted on the slider 46 and the tool assembly 41 can move with the slider 46. The slider 46 is connected to the slide rail 461.

[0095] The slide block 47 has a groove 471 formed thereon that matches the slide rail 461, so that the slide rail 461 can be placed into the groove 471. The shape of the slide rail 461 matches the groove 471, so the movement direction of the slide rail 461 is restricted by the groove 471.

[0096] The drive assembly 48 is used to drive the slider 46 to move. Due to the cooperation between the slide rail 461 and the slide groove 471, the drive assembly 48 can only move along the direction of the slide groove 471.

[0097] A right-angle connecting rod 49 is used to connect the slider 46 and the drive assembly 48, enabling the drive assembly 48 to drive the slider 46 to move.

[0098] The slide rail 461 has a positioning protrusion 472 formed inside the slide groove 471, and a positioning groove 462 that matches the positioning protrusion 472 is formed on the slide rail 461. The positioning protrusion 472 and the positioning groove 462 match each other, which not only restricts the movement direction of the slide rail 461, but also prevents the slider 46 from separating from the slide base 47 by meshing with each other.

[0099] Furthermore, a limiting block 463 is provided at one end of the slider 46, and an adjusting bolt 464 is provided on the limiting block 463. The length of the adjusting bolt 464 that can pass through the limiting block 463 can be changed by rotating the nut 466 on it. When the slider 46 moves, the limiting block 463 will move along the adjusting bolt 464.

[0100] A rubber block 465 is connected to the lower end of the adjusting bolt 464. When the lifting mechanism 42 moves the tool assembly 41, the lower end of the adjusting bolt 464 contacts the base 40, thereby limiting the descent distance of the tool assembly 41. By adjusting the position of the nut 466 on the adjusting bolt 464, the stroke of the limiting block 463 can be limited, thereby further limiting the stroke of the tool assembly 41. The rubber block 465 acts as a buffer, reducing the speed increase of the tool assembly 41 due to inertia during the lifting process, allowing the grinding wheel blade 412 to cut the metal hose at a uniform speed, ensuring a smooth and neat cut.

[0101] Furthermore, both ends of the slider 46 are provided with limit blocks 463 and adjusting bolts 464.

[0102] Furthermore, the drive assembly 48 is a pneumatic piston, and the drive assembly 48 includes:

[0103] The pneumatic cylinder 481 has an air chamber 483 formed inside it;

[0104] The piston rod 482 passes through the pneumatic cylinder 481. A piston top 484 is formed in the middle of the piston rod 482. The size of the piston top 484 matches the air chamber 483, so that the piston top 484 can move in the direction of the air chamber 483 within the air chamber 483. The piston top 484 divides the air chamber 483 into upper and lower parts.

[0105] For ease of explanation, the piston rod 482, which is divided by the piston top 484, is defined as having two ends: the upper end 485 and the lower end 486. The lower end 486 is connected to the right-angle connecting rod 49. When the piston rod 482 moves, the lower end 486 drives the right-angle connecting rod 49, which in turn drives the slider 46 to move up and down, ultimately achieving the purpose of moving the tool assembly 41 up and down.

[0106] A limiting part 487 is fitted onto the upper end 485 of the piston rod. The limiting part 487 cannot enter the pneumatic cylinder 481. Therefore, the limiting part 487 can restrict the overall stroke of the piston rod 482, thereby controlling the lifting and lowering amplitude of the tool assembly 41. In actual production, the stroke of the piston rod 482 can be easily adjusted by regulating the positional relationship between the limiting part 487 and the upper end 485 of the piston rod, thus controlling the lifting and lowering amplitude of the tool assembly 41.

[0107] The pneumatic cylinder 481 has two air holes at its upper and lower ends, designated as air hole one 488 and air hole two 489. For clarity, air hole one 488 is located at the upper end of the pneumatic cylinder 481, and air hole two 489 is located at the lower end. Both air holes one 488 and air hole two 489 are connected to the air chamber 483. These two air holes are used to connect compressed air. By changing the air pressure at the upper and lower ends of the air chamber 483 inside the pneumatic cylinder 481, the piston top 484 moves within the air chamber 483, thereby achieving the purpose of moving the right-angle connecting rod 49 via the piston rod 482.

[0108] Furthermore, the base 40 includes a support base 401 and a tool base 402, which are arranged side by side. A hose support platform 43 is installed on the support base 401, and a lifting mechanism 42 is installed on the tool base 402.

[0109] Furthermore, the guide groove 432 has a semi-circular cross-section and is adapted to the outer diameter of the metal hose.

[0110] The dimensions of the semi-circular surface of the guide groove 432 match the dimensions of the metal hose, allowing the metal hose to be placed into the guide groove 432 without deformation. This facilitates accurate cutting of the metal hose by the grinding wheel blade 412 during hose cutting, resulting in a smoother cut and reducing burrs after cutting.

[0111] In actual cutting, the entire flexible hose is not severed by the abrasive wheel blade 412. It only needs to cut into the hose to a certain depth, allowing the blade to cut the stainless steel strip. After cutting the strip, other mechanisms rotate the two ends of the flexible hose relative to each other, separating the two sections. If the abrasive wheel blade 412 were to cut the entire flexible hose directly, the hose would jump at the moment of cutting, posing a safety hazard. Furthermore, completely cutting the hose is time-consuming, labor-intensive, and results in significant wear and tear on the cut surface.

[0112] Because the metal hose used for shower heads is made of a tightly wound stainless steel strip, it is elastic and has a certain thickness; in the actual cutting process, it is difficult to cut exactly the width of a metal strip; basically, during the cutting process, the metal strips on both sides of the cutting point (referring to both sides along the length of the metal hose) will be damaged; visually, it usually appears as three or more stainless steel strips arranged side by side being cut at the same time; by using the inclined design of the grinding wheel, the stainless steel strips on both sides of the cutting point are staggered, reducing the slight vibration, which can avoid or reduce the appearance of burrs on the cut surface of the stainless steel strips on both sides to a certain extent.

[0113] Furthermore, a rotary unloading mechanism is provided on the right side of the cutting mechanism, which is used to transport the cut metal hose 1 to the outside of the machine body 2.

[0114] Furthermore, the rotary unloading mechanism includes a frame 301, a rotating component 302, a clamping component 303, a first driving component 304, and a through hole. The frame 301 is mounted on the inner plane of the cutting machine; the rotating component 302 is mounted on one side of the frame 301 and can be driven to rotate by an external force; the clamping component 303 is mounted at the front end of the rotating component 302 and is used to tighten or loosen the metal hose; the clamping component 303 rotates synchronously with the rotating component 302; the first driving component 304 is mounted on the other side of the frame 301 and is used to drive the rotating component 302 to rotate; the through hole penetrates the frame 301 and the rotating component 302 and is used for the metal hose 1 to pass through.

[0115] In this technical solution, the clamping component 303 is installed on the front side of the rotating component 302 and rotates synchronously with the rotating component 302. The rotating component 302 is rotatably mounted on the frame 301. The first driving component 304, mounted on the upper side of the frame 301, drives the rotating component 302 to rotate, which in turn drives the clamping component 303 to rotate. A through hole is provided through the middle of the upper part of the rotating component 302 and the frame 301. The metal hose 1 enters the through hole and is clamped by the clamping component 303. After the cutting action is completed, it is rotated by the rotating component 302 to perform the unloading operation and is conveyed to the next mechanism of the pipe cutting machine. This technical solution has a simple structure, is not prone to failure, and has low noise.

[0116] Furthermore, the frame 301 is installed on the internal plane of the cutting machine. It is divided into a first base 311 and a fixed base 321. The first base 311 is installed on the plane, and the fixed base 321 is installed on the first base 311. The fixed base 321 has a through hole in the middle for the metal hose 1 to pass through. A rotary table 3210 is provided on the periphery of one side of the through hole. The rotary table 3210 is in the shape of a ring.

[0117] Furthermore, the rotating component 302 is installed on one side of the fixed base 321 where the rotary table 3210 is provided. The rotating component 302 includes a collar 312, a flange 322, and an extension seat 332. The collar 312 is rotatably installed on the rotary table 3210. The flange 322 is installed on the front side of the collar 312, and the extension seat 332 is installed on the front side of the flange 322. A through hole is provided in the middle of the collar 312, the flange 322, and the extension seat 332. The through hole is connected to the through hole in the middle of the fixed base 321. The collar 312, the flange 322, and the extension seat 332 rotate synchronously.

[0118] Furthermore, a clamping component 303 is installed on the front end of the rotating component 302, i.e., the extension seat 332. The clamping component 303 includes a mounting plate 343, a cylinder body 313, a telescopic rod 323, and two clamping arms 333. The mounting plate 343 is installed on the extension seat 332, the cylinder body 313 is installed on the upper part of the mounting plate 343, the telescopic rod 323 is telescopically installed inside the cylinder body 313, and the clamping arms 333 are divided into a first arm 3330 and a second arm 3331. The first arm 3330 is perpendicular to the second arm 3331. One end of the first arm 3330 of the two clamping arms 333 is rotatably installed on the lower part of the telescopic rod 323. The two clamping arms 333 are arranged opposite each other. The telescopic movement of the telescopic rod 323 can make the two clamping arms 333 move closer or further away from each other, thereby clamping or releasing the metal hose 1.

[0119] Furthermore, the first driving component 304 is disposed on the other side of the first base 311, and includes a drive motor 314, a reducer 334, and a transmission assembly 324. The reducer 334 is mounted on the first base 311, and the drive motor 314 is mounted on the rear side of the reducer 334. The transmission assembly 324 is used to transmit the driving force of the first driving component 304 to the rotating component 302. The transmission assembly 324 includes an external gear ring 3240 and an internal gear ring 3241. The external gear ring 3240 has an internal gear ring 3241. A rack is provided; an internal gear ring 3241, with a rack on its outside, and a sleeve 3242 extending forward from its inner circumference, with a spline portion 3243 at the front end of the sleeve 3242; an external gear ring 3240 is fitted onto the internal gear ring 3241 and meshes with it, and the external gear ring 3240 drives the internal gear ring 3241 to rotate; the sleeve 3242 passes through the through hole in the middle of the fixed seat 321 and is installed on the flange 322, wherein the sleeve 3242 is installed on the flange 322 through the spline portion 3243 at the end of the sleeve 3242.

[0120] Furthermore, a discharge assembly is provided below the first drive component 304, which includes a guide rail 572, a drive component 552, a second-stage sliding component 532, a clamping component 512, and a guide portion 505. The guide rail 572 and the drive component 552 are of the same length and parallel to the horizontal plane. The second-stage sliding component 532 slides on the guide rail 572 and the drive component 552. The clamping component 512 is provided on the second-stage sliding component 532 for clamping or releasing the metal hose 1. A guide portion 505 is provided on the side of the second-stage sliding component 532 away from the frame 301. The guide portion 505 is divided into a guide plane 515 and a guide ramp 525. The guide plane 515 is on the side closer to the frame 301. The guide portion 505 is mounted on the pipe cutting machine. After separation, the metal hose will slide down along the guide portion 505 into the storage tank under the action of gravity. In practice, if the cut metal hose is too short, resulting in insufficient weight for the separated hose to slide down naturally, a length control mechanism can be used for secondary unloading. That is, after cutting and separating the hose, a length control mechanism is used to clamp the metal hose again and then convey one end forward to assist in unloading.

[0121] Furthermore, a length control mechanism for a telescopic metal hose cutter is provided on the right side of the rotary unloading mechanism. This mechanism is used to control the metal hose 1 to be cut to a set length.

[0122] Furthermore, the mechanism includes a fixed reference mechanism 501 and a movable reference mechanism 502. The fixed reference mechanism 501 is used to clamp the rear of the metal hose 1; the movable reference mechanism 502 is used to clamp the rear of the metal hose 1. The movable reference mechanism 502 includes a clamping component 512, a first-stage sliding component 522, a second-stage sliding component 532, an elastic connecting component 542, a driving component 552, and a sensor component 562. The clamping component 512 is used to clamp the metal hose 1 and is mounted on the first-stage sliding component 522. The first-stage sliding component 522 is used to drive the clamping component 512 to move and is mounted on the second-stage sliding component 532. The second-stage sliding component 532 is used to drive the first-stage sliding component 522 to move, and a guide structure is provided on the lower side of the second-stage sliding component 532. The second-stage sliding component 532 slides on the guide structure; the elastic connecting component 542 is used for linkage between the first-stage sliding component 522 and the second-stage sliding component 532; one end of the elastic connecting component 542 is disposed on the second-stage sliding component 532, and the other end of the elastic connecting component 542 is disposed on the first-stage sliding component 522; when the second-stage sliding component 532 drives the first-stage sliding component 522 to move, the elastic connecting component 542 is in a compressed or stretched state; the driving component 552 is used to drive the second-stage sliding component 532 to move along a set direction; the sensor component 562 is mounted on the second-stage sliding component 532 and is used to detect the first-stage sliding component 522; when the first-stage sliding component 522 moves relative to the second-stage sliding component 532 to a set position, the sensor component 562 controls the driving component 552 to stop working.

[0123] Furthermore, the driving component 552 is a rodless cylinder, which is used to drive the second-stage sliding component 532 to reciprocate. It is horizontally mounted on the internal plane of the pipe cutter along the movement direction of the second-stage sliding component 532. The guiding structure is a guide rail 572, which is mounted parallel to the rodless cylinder on the internal plane of the pipe cutter. The lower ends of the second-stage sliding component 532 slide on the rodless cylinder and the guide rail 572 respectively.

[0124] Furthermore, the second-stage sliding component 532 is a cuboid with a groove in its transverse opening; the first-stage sliding component 522 is a cuboid with its lower end entering the groove, and the width of the groove is greater than the width of the lower end of the first sliding component, thereby enabling the first-stage sliding component 522 to move left and right within the groove.

[0125] Furthermore, an elastic connecting member 542 is provided on the first-stage sliding member 522. The elastic connecting member 542 in this technical solution is preferably a torsion spring, one end of which is installed on the first-stage sliding member 522 and the other end is installed on the second-stage sliding member 532. It is used to realize the linkage between the first-stage sliding member 522 and the second-stage sliding member 532. That is, when the second-stage sliding member 532 moves, it drives the first-stage sliding member 522, and the elastic connecting member 542 is in a compressed or stretched state.

[0126] Furthermore, a sensor component 562 is also provided on the second-stage sliding component 532, with its detection end facing the first-stage sliding component 522. When the first-stage sliding component 522 moves to a set position relative to the second-stage sliding component 532, that is, the load force of the elastic connecting component 542 reaches a set value, the metal hose 1 is in a set tension state, and the tension is controlled by the elastic connecting component 542 (i.e., spring). That is, the metal hose 1 between the fixed reference mechanism 501 and the movable reference mechanism 502 is in a set tension state. At this time, the distance between the cutting point of the metal hose and the clamping point of the fixed reference mechanism is a preset standard length, thereby realizing the standard length cutting of the hose. At this time, the sensor component 562 controls the drive component 552 to stop working, thereby causing both the first-stage sliding component 522 and the second-stage sliding component 532 to stop moving.

[0127] Furthermore, the clamping component 512 is divided into a first clamping cylinder 5120 and a second clamping cylinder 5121. The lower right side of the first clamping cylinder 5120 extends forward to form a first sliding foot 5122.

[0128] The second clamping cylinder 5121 extends forward from the lower left side to form a second sliding foot 5123; the upper end of the first-stage sliding component 522 is provided with two first sliding grooves 5220;

[0129] The first sliding foot 5122 and the second sliding foot 5123 slide in the first sliding groove 5220 respectively. When the first clamping cylinder 5120 and the second clamping cylinder 5121 are activated, they move closer or further apart, thereby clamping the metal hose 1 and making the metal hose 1 reach the set tension.

[0130] Furthermore, the fixed reference mechanism 501 of this technical solution is located at the inlet end of the metal hose 1 of the movable reference mechanism 502. The fixed reference mechanism 501 is the metal hose conveying mechanism of the pipe cutting machine. The term "fixed" refers to the fact that the position of this mechanism relative to the "movement" characteristic of the movable reference mechanism 502 is "fixed." This fixed reference mechanism 501 can be a fixed clamp, such as a cylinder clamp, or it can be the metal hose conveying mechanism in this technical solution. That is, after conveying a fixed length of metal hose 1, it locks the metal hose 1, thereby achieving the reference positioning of the metal hose 1. In this embodiment, the fixed reference mechanism 501 is a synchronous belt conveying mechanism. The clamping point of the synchronous belt conveying mechanism clamping the metal hose is the clamping point of the fixed reference mechanism. This mechanism controls the tension of the metal hose, ensuring that the length of the metal hose from the clamping point to the cutting point always meets the standard. In this embodiment, when the upper conveying component 202 and the lower conveying component 203 cooperate to clamp the metal hose and stop conveying, the upper conveying component 202 and the lower conveying component 203 form the fixed reference mechanism 501.

[0131] In this technical solution, the metal hoses delivered by the conveyor belt are basically of standard length each time. When the metal hoses pass through the pre-detection mechanism and enter the conveying mechanism, the tension of the metal hoses is basically consistent. Therefore, the pre-detection mechanism also plays a role in pre-tension adjustment. Of course, even without the pre-detection mechanism, the solution of this application can still be implemented. When the conveying mechanism delivers the metal hoses in the set direction, the side located in the feeding direction is the hose pulling, and the side located in the cutting point is the hose feeding. In fact, when the hose is being pulled, the tension of the metal hoses is basically consistent.

[0132] Example 2:

[0133] This embodiment is basically the same as Embodiment 1, except that:

[0134] like Figure 10 As shown, the rotating component 302 is divided into a flange 322 and a collar 312. When the metal hose passes through the middle, it also achieves the effect of support, making it easy to rotate the metal hose.

[0135] The controller is the electrical control system of the entire device, which controls the operation of the other components of the hose cutter. The controller itself is prior art and will not be described in detail in this application.

[0136] The working process of this patent is as follows: The metal hose is generally a very long tube. It is stored in a coil on a disc below the pre-detection mechanism. The operator manually introduces one end of the hose into the pre-detection mechanism, then into the conveying mechanism, and the program begins. The conveying mechanism transports a certain length of the metal hose forward. The front end of the hose passes through a cutting mechanism, a stripping mechanism, and a length control mechanism. This length is set by controlling the number of rotations of the drive motor of the conveying mechanism. After the set length is reached, the conveying mechanism stops. At this time, the conveying mechanism still clamps the metal hose, and the length control mechanism clamps the hose again and pulls it forward until the sensor component 562 is triggered. At this point, the metal hose is taut, and the tension is constant. By adjusting the tension of the metal hose through the length control device, the length of the metal hose is indirectly controlled. Then... The unloading mechanism clamps the metal hose but does not initiate the unloading process. The program then activates the cutting mechanism, which first clamps one end of the metal hose. Both the cutting and unloading mechanisms clamp the metal hose on either side of the cutting point to prevent the hose from jumping. The program releases the metal hose via the length control device, and the cutting mechanism cuts the hose (or the length control device can be set to release the hose after cutting). After cutting, the rotating component 302 of the cutting mechanism starts working and separates the metal hose. Once separated, the hose is released directly, and it automatically unloads under gravity. All mechanisms reset, and the next round of actions begins with the conveying mechanism.

[0137] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this technical solution. Various changes and modifications can be made to this technical solution without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed technical solution. The scope of protection of this technical solution is defined by the appended claims and their equivalents.
