Description

Technical Field

[0001] The invention relates to the technical field of hose processing, and in particular to an automatic pipe cutting machine capable of cutting to a fixed length. Background Art

[0002] In modern industrial production, hydraulic systems are widely used in many fields such as engineering machinery, automobile manufacturing, aerospace, etc. due to their efficient and stable power transmission characteristics. As an indispensable component in the hydraulic system, hydraulic hoses are responsible for transmitting high-pressure liquids. Their cutting quality and length accuracy directly affect the performance and stability of the entire hydraulic system.

[0003] At present, hose cutting mainly relies on manual operation. When cutting, whether it is shearing or using a rotating cutting blade, the cutting blade is fed from one side of the hose, which easily causes the hose to deform and is not conducive to ensuring the quality of the cut. Under the demand for mass production, the manual cutting method not only consumes a lot of physical strength, but also has low operating efficiency. Moreover, it is difficult to accurately control the cutting length, and the error is high, which makes a large number of hoses unusable due to size deviation, resulting in waste of raw materials and increased production costs. In addition, the different sizes of the cut hoses will increase the difficulty of installation during assembly, which is not conducive to the production progress and product quality of the hydraulic system.

[0004] Therefore, how to achieve fixed-length cutting of the hose while improving cutting efficiency is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0005] In order to achieve fixed-length cutting of rubber hoses while improving cutting efficiency, the present application provides an automatic pipe cutting machine that can cut to fixed length.

[0006] The present application provides an automatic pipe cutting machine capable of cutting to a fixed length, which adopts the following technical solution: An automatic pipe cutting machine capable of cutting to a fixed length comprises a frame, a cutting device and a traction device are mounted on the frame, a rubber hose to be cut axially passes through the traction device and the cutting device, the cutting device is located at the output end of the traction device, an adjusting device is mounted on the traction device, guiding devices are mounted on the frame corresponding to the input ends of the traction device and the cutting device, and a control device electrically connected to the cutting device, the traction device and the adjusting device is mounted on the frame.

[0007] By adopting the above technical solution, the position of the traction device can be adjusted according to the diameter of the hose by using the adjustment device, so as to achieve reliable traction of hoses of different specifications. At the same time, the guiding device can accurately position and guide the hose, ensuring that the hose can smoothly and accurately enter the traction device and cutting device, laying the foundation for precise cutting, effectively improving cutting accuracy and reducing scrap rate. Then, the control device is used for automatic control, so that the traction device can transport the hose according to the set length, and the cutting device can cut in time according to the instructions. The whole process has a high degree of automation, which greatly reduces manual intervention and significantly improves work efficiency.

[0008] Furthermore, the cutting device includes a first mounting seat fixedly mounted on the frame, a knife seat is rotatably connected to the first mounting seat, a first driving mechanism transmission-connected to the knife seat is mounted on the frame, a cutting knife is radially slidably connected to the knife seat, the cutting knife has a knife tip and a blade, a telescopic member transmission-connected to the cutting knife is mounted on the knife seat, and the telescopic member and the first driving mechanism are both electrically connected to the control device.

[0009] By adopting the above technical scheme, the rotation of the cutting knife and the radial expansion and contraction of the cutting knife can be used to achieve circumferential cutting of the hose. Compared with the prior art of cutting from one side of the hose, the squeezing of the hose during the cutting process can be reduced, which is beneficial to ensuring the quality of the hose cut.

[0010] Furthermore, the traction device includes two second mounting seats fixedly mounted on the frame, two groups of parallel rotating shafts are mounted between the two second mounting seats, the adjusting device is slidably mounted on the second mounting seat, the rotating shaft is rotatably connected to the adjusting device, and conveying rollers are fixedly mounted on the rotating shafts located between the two second mounting seats, and conveying belts are respectively mounted on the outer sides of the conveying rollers on the two groups of the rotating shafts, and a first groove is provided on the surface of the conveying belt corresponding to the outer side surface of the hose, and friction teeth are provided on the first groove, and the hose is clamped between the two groups of the conveying belts; at least one of the two groups of the rotating shafts is respectively connected to a second driving mechanism, the second driving mechanism is mounted on the adjusting device, and the second driving mechanism is electrically connected to the control device.

[0011] By adopting the above technical solution, the adjustment device is slidably mounted on the second mounting seat, and the distance between the two sets of rotating shafts can be flexibly adjusted according to the different diameters of the hoses, ensuring that the conveyor belt can always stably clamp and pull the hoses, thereby improving the adaptability of the equipment to hoses of different specifications. In addition, the two sets of parallel conveyor belts are used to clamp the hoses from both sides at the same time, and the fitting design of the first groove and the outer side of the hose and the increased friction of the friction teeth make it difficult for the hose to slip or deviate during the pulling process, thereby ensuring the stability and straightness of the hose pulling, which is conducive to ensuring the cutting accuracy of the hose.

[0012] Furthermore, the adjusting device includes mounting frames respectively installed at both ends of the two groups of rotating shafts, the rotating shafts are rotatably connected to the mounting frames, and at least one screw is screwed on the two mounting frames located at the same end of the two groups of rotating shafts at the same time, and the screw is rotatably installed on the frame, and two symmetrically arranged spiral grooves are respectively provided on the screw corresponding to the two mounting frames, and spiral sleeves are fixedly installed on the mounting frames corresponding to the spiral grooves, and the screw is threadedly connected to the mounting frame through the spiral grooves and the spiral sleeves, and one end of the screw passes through the frame and is transmission-connected to a third driving mechanism, and the third driving mechanism is electrically connected to the control device.

[0013] By adopting the above technical solution, the screw rod and the spiral sleeve are screwed together to accurately convert the rotational motion of the screw rod into the linear motion of the mounting frame. By controlling the rotation angle and number of turns of the screw rod, the distance adjustment amount between the two sets of rotating shafts can be accurately controlled, thereby achieving accurate adaptation of hoses of different diameters and ensuring the stability and reliability of the hoses during the traction process. The symmetrically arranged spiral grooves on the screw rod enable the two sets of mounting frames to move relative to or away from each other synchronously, ensuring that the spacing between the two ends of the two sets of rotating shafts changes simultaneously and in equal amounts. This synchronous adjustment method ensures that the clamping force of the two sets of conveyor belts on the hose is evenly distributed, avoiding the displacement or distortion of the hose during the traction process due to inconsistent spacing between the two ends, thereby improving the traction effect and cutting accuracy.

[0014] Furthermore, the guiding device includes two third mounting seats fixedly mounted on the frame, the two third mounting seats are rotatably connected with a first mounting shaft, the first mounting shaft is fixedly mounted with a first roller, the third mounting seats are provided with a waist-shaped hole corresponding to the first mounting shaft, a second mounting shaft is movably mounted inside the waist-shaped hole, a second roller is fixedly mounted on the second mounting shaft, the first roller and the second roller are both provided with annular guide grooves corresponding to the rubber hose, and the rubber hose is mounted between the first roller and the second roller.

[0015] By adopting the above technical solution, the annular guide grooves on the first roller and the second roller can accurately guide the hose, so that the hose can accurately enter the subsequent traction device and cutting device, thereby improving the accuracy of hose transportation and cutting precision, and reducing cutting errors and scrap rates caused by hose deviation. At the same time, the waist-shaped hole opened on the third mounting seat makes the second mounting shaft movable, so that the second roller can be fine-tuned in position. This design enables the guiding device to adapt to hoses of different diameters, as well as slight size changes or fluctuations of the hose during transportation, enhancing the versatility and adaptability of the equipment to hoses of different specifications.

[0016] Furthermore, the control device includes a fourth mounting seat fixedly mounted on the frame, a controller body fixedly mounted on the fourth mounting seat, the controller body is electrically connected to the cutting device, the traction device and the adjustment device respectively, and control buttons and a display are provided on the controller body.

The operator only needs to set the parameters through the control button, and the equipment can automatically complete a series of operations such as adjustment, pulling and cutting of the hose according to the preset program, which greatly improves work efficiency, reduces manual intervention, and reduces labor intensity. The controller body can accurately control the operation of the adjustment device, pulling device and cutting device to ensure that the parameters such as the cutting length and pulling speed of the hose meet the set requirements, thereby improving the cutting accuracy and product quality and reducing the scrap rate. The setting of the control button and the display allows the operator to easily set parameters and monitor the equipment status. The operator does not need to have complex professional knowledge, but only needs to perform simple operations according to the prompts on the display to complete the functions of starting, stopping and adjusting parameters of the equipment, which reduces the difficulty of operation.

[0018] Furthermore, the first driving mechanism includes a first driving motor fixedly mounted on the frame, the first driving motor is electrically connected to the control device, a first driving gear is fixedly mounted on the output shaft of the first driving motor, an intermediate gear is rotatably mounted on the frame corresponding to the first driving gear, a first driven gear is fixedly mounted on the tool holder corresponding to the intermediate gear, and the intermediate gear is meshed with the first driving gear and the first driven gear at the same time.

[0019] By adopting the above technical solution and utilizing the gear transmission method, the meshing accuracy between the gears is high, which can ensure the stability and accuracy of power transmission. During the cutting process, the knife seat can rotate smoothly, so that the cutting knife can cut the hose evenly, improve the cutting quality, and reduce the jitter and error during the cutting process. At the same time, the gear transmission has a high load-bearing capacity and wear resistance, and can withstand large torque and frequent start-stop operations. During long-term use, the first drive mechanism can maintain stable performance, reduce the probability of failure, and improve the reliability and service life of the equipment. In addition, the first drive motor is electrically connected to the control device, and the control device can accurately control the start, stop and speed of the first drive motor. The operator can flexibly adjust the rotation of the knife seat through the control device according to actual needs, realize automated cutting operations, and improve work efficiency and convenience of operation.

[0020] Furthermore, the second driving mechanism includes a second driving motor fixedly mounted on the mounting frame, the second driving motor is electrically connected to the control device, a second driving gear is fixedly mounted on the output shaft of the second driving motor, at least one of the two groups of rotating shafts has a second driven gear mounted on it corresponding to the second driving gear, and the second driving gear is meshed with the second driven gear.

[0021] By adopting the above technical solution and utilizing the gear transmission method, the meshing between the second driving gear and the second driven gear can realize efficient power transmission, reduce energy loss, and enable the power of the second drive motor to be effectively transmitted to the rotating shaft, thereby ensuring that the traction device can work stably and efficiently. At the same time, the second drive motor is electrically connected to the control device, and the control device can accurately control the parameters such as the start, stop, speed and direction of the second drive motor. By accurately controlling the motor, the traction speed and length of the hose can be accurately controlled, fixed-length transportation can be realized, cutting accuracy can be improved, and different production needs can be met.

[0022] Furthermore, the third driving mechanism includes a third driving motor fixedly mounted on the frame, the third driving motor is electrically connected to the control device, a third driving gear is fixedly mounted on the output shaft of the third driving motor, a transmission shaft is rotationally mounted on the frame corresponding to the third driving gear, a first transmission gear and a second transmission gear are fixedly mounted on the transmission shaft, the first transmission gear is meshed with the third driving gear, a third driven gear is fixedly mounted on one end of the screw rod passing through the frame, and the second transmission gear is simultaneously meshed with all of the third driven gears.

[0023] By adopting the above technical solution, the design of the second transmission gear meshing with the third driven gear on all the screws at the same time can ensure that all the screws rotate synchronously, and then the mounting frames at both ends of the two sets of rotating shafts move synchronously, ensuring that the distance between the two sets of rotating shafts in the traction device is evenly adjusted, avoiding the situation where one end is adjusted more and the other end is adjusted less, and improving the accuracy and stability of the adjustment. At the same time, the third drive motor is electrically connected to the control device, and the control device can accurately control the start, stop, speed and direction of the third drive motor. The operator can conveniently adjust the number of turns and direction of the screw through the control device according to the diameter of the hose, so as to achieve precise adjustment of the position of the traction device, and the operation is simple and convenient.

[0024] Furthermore, a discharge hopper is installed on the frame corresponding to the output end of the cutting device.

[0025] By adopting the above technical solution, the discharge hopper can provide a centralized collection channel for the cut hose segments, preventing the hose segments from being scattered randomly, making the collection work more convenient and efficient. At the same time, the inner wall of the discharge hopper is relatively smooth, and the hose segments can reduce the collision and friction with other parts during the sliding process, reducing the possibility of damage to the hose surface, which is conducive to ensuring the quality of the hose after cutting. It can also prevent the hose segments from being scattered everywhere, keep the workplace clean and orderly, avoid the messy work space caused by the random stacking of hoses, and optimize the overall working environment.

[0026] Beneficial effects achieved: 1. The present application can adjust the position of the traction device by controlling the adjustment device through the control device according to the diameter of the hose, so that the equipment can effectively and reliably pull hoses of different specifications, thereby improving the versatility and applicability of the equipment. There is no need to replace different equipment for hoses of different specifications, thus reducing costs.

[0027] 2. This application uses a guiding device to position and guide the traction of the hose, ensuring that the hose can accurately enter the traction device and the cutting device, which helps to improve the precision and accuracy of the cutting, ensure that the length of the hose after cutting meets the predetermined requirements, and reduce errors and scrap rates.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] The embodiment of the present application discloses an automatic pipe cutting machine capable of cutting to a fixed length.

[0046] Please refer to Figures 1 to 10 In one embodiment of the present application, an automatic pipe cutting machine capable of cutting to a fixed length includes a frame 101, on which a cutting device 200 and a traction device 300 are mounted, the hose 100 to be cut axially penetrates the traction device 300 and the cutting device 200, the cutting device 200 is located at the output end of the traction device 300, an adjusting device 400 is mounted on the traction device 300, guiding devices 500 are mounted on the frame 101 corresponding to the input ends of the traction device 300 and the cutting device 200, and a control device 600 electrically connected to the cutting device 200, the traction device 300 and the adjusting device 400 is mounted on the frame 101.

[0047] The implementation principle of an automatic pipe cutting machine capable of fixed-length cutting in the present application is as follows: During the working process of the present application, firstly, the position of the traction device 300 is adjusted according to the diameter of the hose 100 by controlling the adjustment device 400 through the control device 600 to ensure that the traction device 300 can effectively and reliably pull the hoses 100 of different specifications, and then the hose 100 to be cut is guided into the traction device 300 through the guide device 500 located at the input end of the traction device 300 on the frame 101. Under the control of the control device 600, the traction device 300 pulls the hose 100 according to the set speed and length requirements, and transports the hose 100 along its axial direction for a fixed length. The transported hose 100 of a fixed length enters the cutting device 200 through the guide device 500 located at the input end of the cutting device 200 on the frame 101. The guiding device 500 plays a role in positioning and guiding the hose 100, ensuring that the hose 100 can accurately enter the traction device 300 and the cutting device 200; when the hose 100 is pulled to the set length, the cutting device 200 is started under the instruction of the control device 600 to cut the hose 100 and cut the hose 100 according to the predetermined length. As the core control component, the control device 600 coordinates the work between the traction device 300, the cutting device 200 and the adjustment device 400, ensuring that each device operates in an orderly manner according to the set procedures and parameters, and realizing the automated operation of cutting the hose 100 to a fixed length.

[0048] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the cutting device 200 includes a first mounting seat 201 fixedly mounted on a frame 101, a knife seat 202 is rotatably connected to the first mounting seat 201, a first driving mechanism 700 is installed on the frame 101 and is transmission-connected to the knife seat 202, a cutting knife 203 is radially slidably connected to the knife seat 202, the cutting knife 203 has a knife tip and a blade, a telescopic member 204 is installed on the knife seat 202 and is transmission-connected to the cutting knife 203, and the telescopic member 204 and the first driving mechanism 700 are both electrically connected to the control device 600.

[0049] During operation, the control device 600 sends a command, and the first drive mechanism 700 starts after receiving the signal, driving the knife seat 202 rotatably connected to the first mounting seat 201 to rotate around the central axis of the hose 100. The rotation of the knife seat 202 provides a circular motion basis for the cutting knife 203 to cut the hose 100. At the same time, during the rotation of the knife seat 202, the control device 600 sends a signal to the telescopic member 204, and the telescopic member 204 drives the cutting knife 203 to perform telescopic motion along the radial direction of the knife seat 202 and the hose 100. When the cutting knife 203 is extended, its knife tip and blade will contact and cut into the hose 100 in turn, and with the rotation of the knife seat 202, the cutting action of the hose 100 is completed; after the cutting is completed, the telescopic member 204 drives the cutting knife 203 to retract and move away from the cut hose 100.

[0050] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the first driving mechanism 700 includes a first driving motor 701 fixedly mounted on the frame 101, the first driving motor 701 is electrically connected to the control device 600, a first driving gear 702 is fixedly mounted on the output shaft of the first driving motor 701, an intermediate gear 703 is rotatably mounted on the frame 101 corresponding to the first driving gear 702, a first driven gear 704 is fixedly mounted on the tool holder 202 corresponding to the intermediate gear 703, and the intermediate gear 703 is meshed with the first driving gear 702 and the first driven gear 704 at the same time.

[0051] During operation, the control device 600 sends a control signal to the first drive motor 701. After receiving the signal, the first drive motor 701 starts, and its output shaft starts to rotate, and the first driving gear 702 fixedly mounted on the output shaft rotates synchronously therewith. When the first driving gear 702 rotates, the intermediate gear 703 meshing with it will start to rotate under its drive. The intermediate gear 703 plays the role of transition and power transmission, and transmits the rotation of the first driving gear 702 to the first driven gear 704. Since the first driven gear 704 is fixedly mounted on the knife seat 202, when the intermediate gear 703 drives the first driven gear 704 to rotate, the knife seat 202 will also rotate with the first driven gear 704. The rotation of the knife seat 202 provides a circular motion for the cutting knife 203 mounted thereon, so that the cutting knife 203 can cut the hose in a circular direction.

[0052] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the telescopic member 204 is configured as two symmetrically arranged cylinders, and two mounting grooves 205 corresponding to the cylinders are opened on the tool holder 202. The cylinders are fixedly installed in the mounting grooves 205. The telescopic ends of the two cylinders are fixedly connected to the same tool mounting frame 206, and the cutting knife 203 is centrally installed on the tool mounting frame 206.

[0053] During operation, two symmetrically arranged cylinders are used as telescopic parts 204 to drive the cutting knife 203 to extend and retract, which can ensure that the cutting knife 203 is evenly stressed during the extension and retraction process. Compared with a single driving component, the symmetrical double cylinder design can effectively prevent the cutting knife 203 from tilting or deflecting, so that the cutting knife 203 can accurately cut into the hose 100 and complete the cutting, thereby improving the stability and accuracy of the cutting.

[0054] It is understandable that in other embodiments of the present application, the telescopic member 204 may also be configured as a hydraulic rod, an electric telescopic rod, or other device or mechanism capable of performing linear movement.

[0055] Please refer to Figures 1 to 10 In a specific embodiment of the present application, a knife seat front cover 207 is installed on the end of the knife seat 202 close to the cutting knife 203, and a knife seat rear cover 208 is installed on the frame 101 corresponding to the first mounting seat 201, and the end of the knife seat 202 away from the cutting knife 203 can be rotatably installed on the knife seat rear cover 208.

[0056] During operation, the knife seat 202 will rotate under the drive of the first driving mechanism 700, and the knife seat front cover 207 and the knife seat rear cover 208 jointly protect and support the knife seat 202 and the cutting knife 203. The knife seat front cover 207 is installed at the end of the knife seat 202 close to the cutting knife 203, which can prevent dust, debris, etc. from entering the interior of the knife seat 202, avoid damage to the cylinder, and extend the service life of the cylinder. The knife seat rear cover 208 is installed on the frame 101 at a position corresponding to the first mounting seat 201, and the end of the knife seat 202 away from the cutting knife 203 is rotatably mounted on the knife seat rear cover 208, providing support and positioning for the rotation of the knife seat 202, and ensuring the stability of the knife seat 202 during the rotation process.

[0057] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the first drive motor 701 is configured as a common motor, such as an asynchronous motor. The asynchronous motor is an AC motor that operates based on the principle of electromagnetic induction. It has a simple structure, reliable operation, low price, easy maintenance, high efficiency and good mechanical properties.

[0058] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the traction device 300 includes two second mounting seats 301 fixedly mounted on the frame 101, two sets of parallel rotating shafts 302 are installed between the two second mounting seats 301, the adjusting device 400 is slidably mounted on the second mounting seats 301, the rotating shaft 302 is rotatably connected to the adjusting device 400, and the rotating shaft 302 is fixedly mounted with a conveying roller 303 between the two second mounting seats 301, and the outer sides of the conveying rollers 303 on the two sets of rotating shafts 302 are respectively mounted with conveying belts 304, and the surface of the conveying belt 304 is provided with a first groove 305 corresponding to the outer side of the hose 100, and the first groove 305 is provided with friction teeth 306, and the hose 100 is clamped between the two sets of conveying belts 304; at least one of the two sets of rotating shafts 302 is respectively connected to the second driving mechanism 800, the second driving mechanism 800 is mounted on the adjusting device 400, and the second driving mechanism 800 is electrically connected to the control device 600.

[0059] During operation, first, according to the diameter of the hose 100, the control device 600 controls the adjustment device 400 to slide on the second mounting seat 301, thereby adjusting the distance between the two sets of parallel rotating shafts 302 to ensure that the hose 100 can be stably clamped between the two sets of conveyor belts 304. The control device 600 sends a command to the second driving mechanism 800, and the second driving mechanism 800 starts to transmit power to the rotating shaft 302 connected thereto. The rotating shaft 302 will drive the two sets of conveyor belts 304 to run accordingly through the conveying roller 303, and the hose 100 is clamped between the two sets of conveyor belts 304 with the first groove 305 and the friction teeth 306. As the conveyor belts 304 move, the first groove 305 fits the outer side of the hose 100, and the friction teeth 306 increase the friction force, so that the hose 100 is pulled and moved by the conveyor belt 304 along the axial direction under the action of the friction force, and is transported in a fixed length according to the set speed and length requirements.

[0060] Please refer to Figures 1 to 10 In a specific embodiment of the present application, a protective cover 307 is detachably mounted on the second mounting seat 301 , and a avoidance opening 308 is opened in the protective cover 307 corresponding to the axial direction of the hose 100 .

[0061] During operation, the protective cover 307 can effectively prevent foreign debris, dust, etc. from entering the traction device 300, preventing them from causing wear or damage to the rotating shaft 302, the conveying roller 303, the conveying belt 304 and other components, thereby extending the service life of the equipment. The hose 100 passes through the protective cover 307 along the axial direction through the avoidance opening 308 and enters the working area of ​​the traction device 300. When it is necessary to inspect, maintain or replace the internal components of the traction device 300, the protective cover 307 can be removed from the second mounting seat 301 to facilitate the operation of the staff.

[0062] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the second driving mechanism 800 includes a second driving motor 801 fixedly mounted on the mounting frame 401, the second driving motor 801 is electrically connected to the control device 600, a second driving gear 802 is fixedly mounted on the output shaft of the second driving motor 801, and a second driven gear 803 is mounted on at least one of the two sets of rotating shafts 302 corresponding to the second driving gear 802, and the second driving gear 802 is meshed with the second driven gear 803.

[0063] During operation, the control device 600 sends a control signal to the second drive motor 801 according to preset parameters such as traction speed and length. After receiving the signal, the second drive motor 801 starts, and its output shaft starts to rotate, and the second driving gear 802 installed on the output shaft rotates synchronously. The rotating second driving gear 802 meshes with the second driven gear 803 on at least one rotating shaft 302, and transmits the power of the second drive motor 801 to the rotating shaft 302 through gear transmission, so that the rotating shaft 302 starts to rotate. Since the rotating shaft 302 is fixedly mounted with a conveying roller 303, and the outer side of the conveying roller 303 is mounted with a conveying belt 304, the rotation of the rotating shaft 302 drives the conveying roller 303 to rotate, thereby moving the conveying belt 304. The hose 100 is sandwiched between the two sets of conveying belts 304, and under the friction of the conveying belts 304, the hose 100 is pulled and transported along the axial direction.

[0064] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the second drive motor 801 is configured as a servo motor, which is generally composed of a motor, an encoder, and a controller. The controller controls the operation of the motor according to the input command signal (such as position and speed commands). The encoder feeds back the actual position, speed and other information of the motor to the controller in real time. The controller compares the feedback value with the command value and adjusts the output of the motor according to the deviation, thereby achieving precise position and speed control.

[0065] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the adjusting device 400 includes mounting frames 401 respectively mounted at both ends of the two sets of rotating shafts 302, the rotating shafts 302 are rotatably connected to the mounting frames 401, and at least one screw 402 is screwed on the two mounting frames 401 located at the same end of the two sets of rotating shafts 302 at the same time, and the screw 402 is rotatably mounted on the frame 101, and two symmetrically arranged spiral grooves 403 are respectively provided on the screw 402 corresponding to the two mounting frames 401, and spiral sleeves 404 are fixedly installed on the mounting frames 401 corresponding to the spiral grooves 403, and the screw 402 is screwed with the mounting frame 401 through the spiral grooves 403 and the spiral sleeves 404, and one end of the screw 402 that passes through the frame 101 is transmission-connected to the third driving mechanism 900, and the third driving mechanism 900 is electrically connected to the control device 600.

[0066] During operation, when the distance between the two sets of rotating shafts 302 in the traction device 300 needs to be adjusted according to the diameter of the hose 100, the control device 600 will send a command to the third driving mechanism 900. After the third driving mechanism 900 is started, it drives the screw 402 connected thereto to rotate. Since the two mounting frames 401 corresponding to the same end of the two sets of rotating shafts 302 on the screw 402 are respectively provided with two symmetrically arranged spiral grooves 403, and the spiral sleeves 404 are fixedly installed on the mounting frames 401 corresponding to the spiral grooves 403, the screw 402 is screwed to the mounting frame 401 through the spiral grooves 403 and the spiral sleeves 404. Therefore, when the screw 402 rotates, the two mounting frames 401 will make relative or opposite linear motions along the screw 402. Because the mounting bracket 401 is rotatably connected to the rotating shaft 302, the mounting brackets 401 at both ends of the two sets of rotating shafts 302 will drive the rotating shafts 302 to make relative or opposite linear motions, thereby adjusting the distance between the two sets of rotating shafts 302 and the two sets of conveyor belts 304 to meet the needs of traction of hoses 100 of different diameters.

[0067] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the third driving mechanism 900 includes a third driving motor 901 fixedly mounted on the frame 101, the third driving motor 901 is electrically connected to the control device 600, a third driving gear 902 is fixedly mounted on the output shaft of the third driving motor 901, a transmission shaft 903 is rotatably mounted on the frame 101 corresponding to the third driving gear 902, a first transmission gear 904 and a second transmission gear 905 are fixedly mounted on the transmission shaft 903, the first transmission gear 904 is meshed with the third driving gear 902, and a third driven gear 906 is fixedly mounted on one end of the screw rod 402 that passes through the frame 101, and the second transmission gear 905 is simultaneously meshed with all the third driven gears 906.

[0068] During operation, the third driving mechanism 900 is mainly used to drive the screw 402 in the adjusting device 400 to rotate, thereby adjusting the position of the traction device 300 to adapt to hoses of different diameters. The control device 600 sends a control signal to the third driving motor 901 according to the diameter information of the hose. After receiving the signal, the third driving motor 901 starts, and its output shaft starts to rotate, and the third driving gear 902 fixedly mounted on the output shaft rotates synchronously. The rotating third driving gear 902 meshes with the first transmission gear 904 on the transmission shaft 903, and the power of the third driving motor 901 is transmitted to the transmission shaft 903 through gear transmission, so that the transmission shaft 903 starts to rotate. When the transmission shaft 903 rotates, the second transmission gear 905 on it also rotates. Since the second transmission gear 905 meshes with the third driven gears 906 on all the screws 402 at the same time, the rotation of the second transmission gear 905 will drive all the third driven gears 906 to rotate synchronously, thereby causing all the screws 402 to rotate simultaneously. When the screw rod 402 rotates, the mounting frame 401 will move linearly along the screw rod 402 because the spiral sleeve 404 on the mounting frame 401 is screwed with the spiral groove 403 of the screw rod 402. Because the mounting frame 401 is rotatably connected to the rotating shaft 302, the distance between the two sets of rotating shafts 302 will change accordingly, thereby achieving the adjustment of the position of the traction device 300 to adapt to hoses of different diameters.

[0069] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the third drive motor 901 is configured as a stepper motor, which is a motor that converts an electrical pulse signal into an angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (step angle) in the set direction. It can achieve more precise angle positioning, and a higher positioning accuracy can be achieved in an open-loop control system. And by controlling the number of pulses, the angle of the motor can be accurately controlled, and the speed of the motor can be adjusted by controlling the pulse frequency. During operation, it can respond quickly to pulse signals and achieve fast start, stop, and forward and reverse rotation.

[0070] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the guiding device 500 includes two third mounting seats 501 fixedly mounted on the frame 101, the two third mounting seats 501 are rotatably connected with the first mounting shaft 502, the first mounting shaft 502 is fixedly mounted with the first roller 503, the third mounting seats 501 are provided with a waist-shaped hole 504 corresponding to the first mounting shaft 502, the waist-shaped hole 504 is movably mounted with the second mounting shaft 505, the second mounting shaft 506 is fixedly mounted with the second mounting shaft 505, the first roller 503 and the second roller 506 are both provided with annular guide grooves 507 corresponding to the hose 100, and the hose 100 is erected between the first roller 503 and the second roller 506.

[0071] During operation, when the rubber hose 100 to be cut is transported to the guide device 500, the rubber hose 100 is mounted between the first roller 503 and the second roller 506, and fits into the annular guide groove 507 on their surfaces. The first roller 503 is rotatably connected to the two third mounting seats 501 through the first mounting shaft 502, and the second roller 506 is mounted in the waist-shaped hole 504 of the third mounting seat 501 through the second mounting shaft 505. When the rubber hose 100 moves forward under the action of the traction device 300, friction is generated between the rubber hose 100 and the first roller 503 and the second roller 506, driving the first roller 503 and the second roller 506 to rotate. Due to the guiding effect of the annular guide groove 507, it is ensured that the rubber hose 100 can accurately enter the traction device 300 or the cutting device 200 along the predetermined path. At the same time, the second mounting shaft 505 can move in the waist-shaped hole 504 , so that the second roller 506 can be finely adjusted in position according to the diameter of the hose 100 or slight changes during the conveying process, thereby ensuring stable guidance of the hose 100 .

[0072] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the control device 600 includes a fourth mounting seat 601 fixedly mounted on the frame 101, and a controller body 602 is fixedly mounted on the fourth mounting seat 601.

[0073] During operation, the operator inputs relevant working parameters, such as the cutting length of the hose, the pulling speed, the adjustment amount of the adjusting device 400 on the pulling device 300, etc., through the control button 603 on the controller body 602. These parameter information is stored in the controller body 602 as the basis for subsequent equipment operation. The controller body 602 sends control signals to the adjusting device 400, the pulling device 300 and the cutting device 200 respectively according to the preset parameters. For the adjusting device 400, the controller body 602 controls the third driving mechanism 900 to drive the screw 402 to rotate, thereby adjusting the distance between the two sets of rotating shafts 302 in the pulling device 300 to adapt to hoses of different diameters. For the pulling device 300, the controller body 602 controls the second driving mechanism 800 to drive the rotating shaft 302 to rotate, so that the conveyor belt 304 pulls the hose 100 according to the set speed and length requirements. When the hose 100 is pulled to the set length, the controller body 602 sends a command to the cutting device 200, controls the first driving mechanism 700 to drive the knife seat 202 to rotate, and controls the telescopic member 204 to drive the cutting knife 203 to extend for cutting. During the operation of the equipment, the controller body 602 receives the operating status information fed back by each device in real time, such as the actual pulling speed of the pulling device 300, the number of cutting times of the cutting device 200, etc. This information will be intuitively displayed on the display 604, which is convenient for the operator to monitor the operation of the equipment in real time.

[0074] Please refer to Figures 1 to 10 In a specific embodiment of the present application, a discharge hopper 102 is installed on the frame 101 corresponding to the output end of the cutting device 200, and the inner wall of the discharge hopper 102 is provided with a smooth inclined surface.

[0075] During operation, when the cutting device 200 completes cutting of the hose 100 according to the set program, the cut hose segments will fall from the output end of the cutting device 200 under the force of their own gravity and the subsequent push of the conveyor belt 304. The discharge hopper 102 is installed at the position of the frame 101 corresponding to the output end of the cutting device 200, just to receive these cut hose segments, so that the hose segments slide along the inner wall of the discharge hopper 102 to the designated collection position.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
