[0003] However, the existing hose cutting devices have the following technical problems that need to be urgently solved in practical applications: Firstly, during the cutting process, due to the lack of effective fixing and buffering mechanisms, the hose is easily squeezed by the cutting blade and causes local deformation, resulting in uneven cuts and dimensional deviations, seriously affecting the sealing performance of the hose and the subsequent usage effect; Secondly, the existing devices usually only have a single cutting function and cannot perform synchronous grinding treatment on the cut ends of the hoses, making there are defects such as burrs and flash at the cut, which not only reduces the aesthetics of the product but also may pose a risk of scratching to the operators during use; Thirdly, the hoses after cutting lack an orderly collection system and often scatter or pile up randomly, requiring manual secondary sorting and packaging, increasing the labor intensity and production cycle, and it is difficult to meet the modern production requirements of automation and high efficiency.

[0015] A method for using an adjustable cutting device for hose production and processing, comprising the following steps: S1. Pass the hose through between the two driving wheels and insert it into the guiding tube. Start the rotating motor. The rotating motor drives the first driving bevel gear and the upper driving wheel to rotate. The rotation of the driving wheel drives the hose to slide along the direction of the guiding tube. The rotation of the first driving bevel gear drives the first driven bevel gear to rotate, and then drives the second driving bevel gear to rotate through the transmission rod. The second driving bevel gear drives the second driven bevel gear to rotate, and then drives the reciprocating lead screw to rotate. The reciprocating lead screw drives the sliding sleeve to slide back and forth along its axis. During the sliding process of the sliding sleeve, the rack is driven to slide horizontally through the connecting rod. The sliding of the rack drives the gear to rotate. The rotation of the gear drives the rotating rod and the support plate to rotate; S2. Start the electric push rod and the cutting motor. The electric push rod first contracts to pull the mounting plate to rise along the V-shaped groove of the second guiding plate close to the track of the electric push rod. When the second cube disengages from the second guiding plate, the first cube is pressed into the rectangular groove of the first guiding plate by the spring. The electric push rod extends, and the electric push rod pushes the mounting plate to move horizontally away from the electric push rod along the rectangular groove; During the process of rising along the V-shaped groove, the mounting plate drives the disc to rise through the lifting rod slidably connected to its top. The rising of the disc causes the internal space of the air cylinder to become larger, the air pressure to become smaller to form a negative pressure, and gas is inhaled through the pipeline from the air groove opened on the fixed pipe. Since the outer wall of the hose is in close contact with the inner wall of the fixed pipe, the fixed pipe will generate a suction force on the hose at the air groove. As the mounting plate rises, the suction force gradually increases, so that the hose will not be squeezed and deformed during the cutting process. The cutting motor drives the cutting blade and the grinding blade to pass through the gap between the two fixed pipes in turn through the pulley to cut and grind the hose; S3. After cutting and grinding are completed, the cutting motor is turned off. The electric push rod contracts to drive the mounting plate to descend along the V-shaped groove away from the track of the electric push rod until it descends to the lowest point of the V-shaped groove. Start the rotating motor. The rotating motor drives the driving wheel to rotate. The driving wheel drives the hose to move, and the cut hose is extruded from the fixed pipe. The cut hose falls on the aggregate table. The rotating motor drives the support plate to rotate into the storage groove through the driving assembly. The cut hose rolls down to the bottom end of the top surface of the aggregate table along the inclined surface of the top of the aggregate table. The rotating motor continues to drive the driving wheel to rotate until when the hose moves a predetermined length, the support plate just resets.

[0016] Compared with the related technology, the adjustable cutting device for hose production and processing provided by the present invention and its using method have the following beneficial effects: High-precision cutting and surface quality improvement: Avoid hose deformation: Through the negative pressure adsorption and fixation system composed of the air cylinder - disc - air groove, a uniform adsorption force is formed instantaneously during cutting, replacing traditional mechanical clamping, and completely solving the problem of hose being squeezed and deformed; Synchronous grinding process: The cutting disc and the grinding disc are integrated on the same mounting plate. After cutting, the cut is immediately ground to eliminate burrs and flash, realizing the integration of "cutting - grinding". Precise track control: The rectangular groove, triangular groove and V - shaped groove of the guiding component are designed in coordination to ensure the straightness of the cutting path, avoiding the skewness of the cut caused by track deviation in traditional devices and significantly improving the cutting accuracy.

[0017] Automated production and efficiency breakthrough: Full - process linkage: A multi - stage transmission system composed of a driving wheel, a reciprocating lead screw, and a rack and pinion seamlessly connects the hose conveying, cutting action and discharging and collecting, realizing the coordinated operation of multiple processes driven by a single motor; Intelligent length control: The thread groove design of the reciprocating lead screw is precisely matched with the rotational speed of the driving wheel to ensure that each cutting length is consistent, eliminating the need for manual measurement and meeting the requirements of batch production; Quick track switching: The elastic connection mechanism of the slider - spring - cube enables the mounting plate to smoothly transition between inclined rising and horizontal cutting, shortening the single - cycle operation time.

Specific implementation manner

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] The specific implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0022] As Figures 1 to 11 shown, an adjustable cutting device for hose production and processing and its use method, the adjustable cutting device for hose production and processing includes: a cutting table 1, a driving wheel 2 for driving the hose to move is symmetrically installed at one end of the top of the cutting table 1, and a cutting blade 3 for cutting the hose is installed at the other end of the top of the cutting table 1; a guiding tube 4 is fixedly connected to the top of the cutting table 1, and the guiding tube 4 cooperates with the driving wheel 2 to make the hose move in a predetermined direction; a grinding sheet 5 for grinding the end of the hose is installed on one side of the cutting blade 3, a mounting plate 6 is installed inside the cutting table 1, and one end of the mounting plate 6 is rotatably connected to the cutting blade 3 and the grinding sheet 5; a guiding component is installed inside the cutting table 1, and the guiding component guides the mounting plate 6 to drive the cutting blade 3 and the grinding sheet 5 to move; a fixing component is installed on the top of the cutting table 1, and the fixing component fixes the hose when cutting the hose; an aggregate table 7 is fixedly connected to one side of the cutting table 1, and a plurality of groups of support plates 8 are rotatably connected to the top of the aggregate table 7 at equal intervals, and the support plates 8 and the aggregate table 7 jointly support the hose to be cut; a mounting frame 9 is fixedly connected to the top of the cutting table 1, a driving component is installed inside the mounting frame 9, and the driving component drives the support plate 8 to rotate so that the cut hose rolls to the collection end on the top surface of the aggregate table 7.

[0023] The device realizes the automatic cutting and collection of the hose through the cooperation of multiple components: the driving wheel 2 conveys the hose to the guiding pipe 4, and the guiding pipe 4 ensures that the hose moves along a predetermined path to the cutting area; during cutting, the fixing component fixes the hose by negative pressure adsorption to prevent the hose from deforming during the cutting process; the mounting plate 6 drives the cutting blade 3 and the grinding blade 5 to complete cutting and end grinding in sequence; the cut hose is received by the aggregate table 7, and the driving component controls the support plate 8 to rotate, so that the finished product rolls to the collection end; the whole process forms a closed loop of "feeding → fixing → cutting and grinding → discharging", improving production efficiency and quality stability.

[0024] As Figure 1 , Figure 2 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the guiding component includes: the first guiding plate 10, the second guiding plate 11, the slider 12, the cylindrical rod 13, the first cube 14, the first spring 15, the second cube 16 and the second spring 17; the first guiding plate 10 and the second guiding plate 11 are fixedly connected inside the cutting table 1, the slider 12 is installed between the first guiding plate 10 and the second guiding plate 11, one end of the mounting plate 6 is fixedly connected with the slider 12 through the cylindrical rod 13, the first cube 14 is slidably connected to one end of the slider 12 close to the first guiding plate 10, the first spring 15 is installed between the first cube 14 and the slider 12, and both ends of the first spring 15 are fixedly connected with the slider 12 and the first cube 14 respectively; the second cube 16 is slidably connected to one end of the slider 12 close to the second guiding plate 11, the second spring 17 is installed between the second cube 16 and the slider 12, and both ends of the second spring 17 are fixedly connected with the slider 12 and the second cube 16 respectively; a through circular groove 34 is opened in the middle of the first cube 14, and the first cube 14 is slidably connected with the cylindrical rod 13 through the circular groove 34; a rectangular groove 35 and a through triangular groove 36 are opened on one side of the first guiding plate 10 close to the slider 12, the depth of one end of the rectangular groove 35 close to the cutting blade 3 gradually becomes shallower, the first cube 14 slides in the rectangular groove 35, and the cylindrical rod 13 slides in the triangular groove 36; a V-shaped groove 37 is opened on one side of the second guiding plate 11 close to the slider 12, the depth of one end of the V-shaped groove 37 close to the grinding blade 5 gradually becomes shallower, and the second cube 16 slides in the V-shaped groove 37.

[0025] Initial state: The slider 12 is located at the corner at the bottom of the V-shaped groove 37 of the second guiding plate 11. The first cube 14 and the second cube 16 are respectively connected with the slider 12 through the first spring 15 and the second spring 17. At this time, the first cube 14 does not contact the rectangular groove 35 of the first guiding plate 10, the first cube 14 shrinks into the slider 12 and compresses the first spring 15, and the second cube 16 is squeezed by the second spring 17 and inserted into the V-shaped groove 37 and is located at the lowest point of the V-shaped groove 37; Ascending stage: The electric push rod 41 contracts, the mounting plate 6 drives the slider 12 to move closer and ascend along the V-shaped groove 37. The second cube 16 slides within the V-shaped groove 37 and compresses the second spring 17. The cylindrical rod 13 slides synchronously within the triangular groove 36 to ensure the inclined ascent of the mounting plate 6. Track switching: When the slider 12 ascends to the top of the V-shaped groove 37, the second cube 16 disengages from the V-shaped groove 37, and the first spring 15 pushes the first cube 14 to snap into the rectangular groove 35 of the first guide plate 10, achieving the track switching from inclined ascent to horizontal movement. Horizontal cutting stage: The electric push rod 41 extends, the mounting plate 6 moves horizontally along the rectangular groove 35. The first cube 14 slides within the rectangular groove 35, and the cylindrical rod 13 slides within the triangular groove 36 to ensure that the cutting blade 3 cuts the hose linearly. Descending and resetting stage: After cutting is completed, the electric push rod 41 contracts again. The mounting plate 6 drives the slider 12 to descend along the track away from the electric push rod 41 along the V-shaped groove 37. The second cube 16 snaps back into the V-shaped groove 37, and the first cube 14 disengages from the rectangular groove 35. Finally, the slider 12 returns to the initial position at the bottom of the V-shaped groove 37. This design realizes the precise motion trajectory control of the mounting plate 6 through track switching.

[0026] As Figure 6 , Figure 7 shown, the fixing assembly includes: an air cylinder 18, a disc 19, a lifting rod 20, a fixed pipe 21, and an air groove 22. The top of the cutting table 1 is fixedly connected with an air cylinder 18. The inner wall of the air cylinder 18 is slidably connected with a disc 19. The disc 19 is sealed with the inner wall of the air cylinder 18. The bottom of the disc 19 is fixedly connected with a lifting rod 20 for driving the movement of the disc 19. The bottom of the lifting rod 20 is slidably connected with the top of the mounting plate 6. The top of the cutting table 1 is fixedly connected with fixed pipes 21 at both ends of the cutting blade 3. The inner walls of the two fixed pipes 21 close to the cutting blade 3 are each provided with an air groove 22. The tops of the two air grooves 22 are connected through a pipeline, and the other end of the pipeline is connected with the bottom of the air cylinder 18. The inner diameter of the inner wall of the fixed pipe 21 is the same as the outer diameter of the hose. When the hose passes through the fixed pipe 21, the outer wall of the hose fits against the inner wall of the fixed pipe 21.

[0027] The fixing component fixes the hose by negative pressure adsorption: when the mounting plate 6 rises, the lifting rod 20 drives the disc 19 in the air cylinder 18 to move upward synchronously, increasing the space in the air cylinder 18 to form negative pressure; the negative pressure is conducted through the pipeline to the air groove 22 of the fixing pipe 21. Since the inner wall of the fixing pipe 21 is in close contact with the outer wall of the hose, a uniform adsorption force is generated at the air groove 22 to fix the hose; as the rising height of the mounting plate 6 increases, the upward movement distance of the disc 19 increases, the negative pressure increases, and the adsorption force increases synchronously to ensure that the hose always remains stable during the cutting process. When the mounting plate 6 slides horizontally along the rectangular groove 35, the position of the lifting rod 20 relative to the cutting table 1 remains unchanged, and the lifting rod 20 and the mounting plate 6 slide relative to each other; when the mounting plate 6 descends, the lifting rod 20 will drive the disc 19 to descend, thereby releasing the fixation of the hose; this method avoids the deformation of the hose caused by traditional mechanical clamping, and is especially suitable for thin-walled or special-shaped hoses.

[0028] As Figure 3 , Figure 4 , Figure 5 shown, the driving component includes: a first driving bevel gear 23, a first driven bevel gear 24, a transmission rod 25, a second driving bevel gear 26, a second driven bevel gear 27, a reciprocating lead screw 28, a sliding sleeve 29, a rotating rod 30, a gear 31, a rack 32 and a connecting rod 33; at one end inside the mounting frame 9, a first driving bevel gear 23 and a first driven bevel gear 24 are rotatably connected. The first driving bevel gear 23 is meshed and connected with the first driven bevel gear 24. The first driving bevel gear 23 is fixedly connected to the driving wheel 2 through a shaft rod. The transmission rod 25 is rotatably connected inside the mounting frame 9. One end of the transmission rod 25 is fixedly connected to the first driven bevel gear 24, and the other end of the transmission rod 25 is fixedly connected to a second driving bevel gear 26. At one end inside the mounting frame 9 near the second driving bevel gear 26, a second driven bevel gear 27 is rotatably connected. The bottom of the second driven bevel gear 27 is fixedly connected to a reciprocating lead screw 28. The outer wall of the reciprocating lead screw 28 is threadedly connected with a sliding sleeve 29. The middle of the aggregate table 7 is rotatably connected with a rotating rod 30. The rotating rod 30 is fixedly connected to multiple support plates 8. One end of the rotating rod 30 near the cutting table 1 is inserted into the cutting table 1 and fixedly connected to a gear 31. The rack 32 is slidably connected inside the cutting table 1. The rack 32 is meshed and connected with the gear 31. The bottom of the rack 32 is rotatably connected with a connecting rod 33. One end of the connecting rod 33 is rotatably connected to the sliding sleeve 29; the horizontal position of the top end of the thread groove formed on the outer wall of the reciprocating lead screw 28 is lower than the horizontal position of the bottom surface of the rack 32; when the hose moves a specified length, the sliding sleeve 29 just slides back and forth along the reciprocating lead screw 28.

[0029] The driving component realizes the linkage of cutting and discharging through multi-stage transmission: the rotating motor 38 drives the first driving bevel gear 23, which drives the first driven bevel gear 24 through meshing, and the power is transmitted to the second driving bevel gear 26 and the second driven bevel gear 27 through the transmission rod 25; the second driven bevel gear 27 drives the reciprocating lead screw 28 to rotate, so that the sliding sleeve 29 makes a reciprocating linear motion along the axis; the sliding sleeve 29 drives the rack 32 to slide horizontally back and forth through the connecting rod 33, and the rack 32 meshes with the gear 31 to drive the rotating rod 30 to rotate reciprocally, thereby controlling the support plate 8 to rotate and retract and reset in the receiving groove 42; the thread groove design of the reciprocating lead screw 28 ensures that when the sliding sleeve 29 completes a reciprocating cycle, the hose just moves a predetermined cutting length, realizing the precise synchronization of cutting and discharging; this design enables the device to complete complex action coordination only through mechanical transmission without an additional control unit.

[0030] A method for using an adjustable cutting device for hose production and processing includes the following steps: S1. Pass the hose through between the two driving wheels 2 and insert it into the guiding tube 4. Start the rotating motor 38. The rotating motor 38 drives the first driving bevel gear 23 and the upper driving wheel 2 to rotate. The rotation of the driving wheel 2 drives the hose to slide along the direction of the guiding tube 4. The rotation of the first driving bevel gear 23 drives the first driven bevel gear 24 to rotate, and then drives the second driving bevel gear 26 to rotate through the transmission rod 25. The second driving bevel gear 26 drives the second driven bevel gear 27 to rotate, and then drives the reciprocating lead screw 28 to rotate. The reciprocating lead screw 28 drives the sliding sleeve 29 to slide reciprocally along its axis. During the sliding process of the sliding sleeve 29, it drives the rack 32 to slide horizontally through the connecting rod 33. The sliding of the rack 32 drives the gear 31 to rotate. The rotation of the gear 31 drives the rotating rod 30 and the support plate 8 to rotate; S2. Start the electric push rod 41 and the cutting motor 39. The electric push rod 41 first contracts to pull the mounting plate 6 to rise along the V-shaped groove 37 of the second guiding plate 11 close to the track of the electric push rod 41. When the second cube 16 is disengaged from the second guiding plate 11, the first cube 14 is pressed into the rectangular groove 35 of the first guiding plate 10 by the spring, and the electric push rod 41 extends. The electric push rod 41 pushes the mounting plate 6 to move horizontally along the rectangular groove 35 in the direction away from the electric push rod 41; during the process of the mounting plate 6 rising along the V-shaped groove 37, it will drive the disc 19 to rise through the lifting rod 20 slidably connected to its top. The rising of the disc 19 causes the internal space of the air cylinder 18 to become larger and the air pressure to become smaller, forming a negative pressure, and inhaling gas through the pipeline from the air groove 22 opened in the fixed pipe 21. Since the outer wall of the hose is in close contact with the inner wall of the fixed pipe 21, the fixed pipe 21 will generate a suction force on the hose at the air groove 22. As the mounting plate 6 rises, the suction force gradually increases, so that the hose will not be squeezed and deformed during the cutting process. The cutting motor 39 drives the cutting blade 3 and the grinding blade 5 to pass through the gap between the two fixed pipes 21 in sequence to cut and grind the hose; S3. After cutting and grinding are completed, the cutting motor 39 is turned off. The electric push rod 41 contracts to drive the mounting plate 6 to descend along the V-shaped groove 37 away from the track of the electric push rod 41 until it descends to the lowest point of the V-shaped groove 37. Then the rotating motor 38 is started. The rotating motor 38 drives the driving wheel 2 to rotate, and the driving wheel 2 drives the hose to move, extruding the cut hose out of the fixed pipe 21. The cut hose falls onto the aggregate table 7. The rotating motor 38 drives the support plate 8 to rotate into the storage groove 42 through the driving assembly. The cut hose rolls down along the inclined surface at the top of the aggregate table 7 to the bottom end of the top surface of the aggregate table 7. The rotating motor 38 continues to drive the driving wheel 2 to rotate until when the hose moves a predetermined length, the support plate 8 just returns to its original position.

[0031] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.

10. A method for using an adjustable cutting device for hose production and processing, characterized in that, Adopt an adjustable cutting device for hose production and processing described in claims 1-9, including the following steps: S1. Pass the hose through between the two driving wheels (2) and insert it into the guiding pipe (4). Start the rotary motor (38). The rotary motor (38) drives the first driving bevel gear (23) and the upper driving wheel (2) to rotate. The rotation of the driving wheel (2) drives the hose to slide along the direction of the guiding pipe (4). The rotation of the first driving bevel gear (23) drives the first driven bevel gear (24) to rotate. Then, through the transmission rod (25), the second driving bevel gear (26) is driven to rotate. The second driving bevel gear (26) drives the second driven bevel gear (27) to rotate, and then drives the reciprocating lead screw (28) to rotate. The reciprocating lead screw (28) drives the sliding sleeve (29) to slide axially back and forth along it. During the sliding process of the sliding sleeve (29), the rack (32) is driven to slide horizontally through the connecting rod (33). The sliding of the rack (32) drives the gear (31) to rotate. The rotation of the gear (31) drives the rotating rod (30) and the support plate (8) to rotate; S2. Start the electric push rod (41) and the cutting motor (39). The electric push rod (41) first contracts to pull the mounting plate (6) to rise along the V-shaped groove (37) of the second guide plate (11) towards the track of the electric push rod (41). When the second cube (16) disengages from the second guide plate (11), the first cube (14) is pressed into the rectangular groove (35) of the first guide plate (10) by the spring. Then the electric push rod (41) extends, and the electric push rod (41) pushes the mounting plate (6) to move horizontally along the rectangular groove (35) in the direction away from the electric push rod (41). During the process of rising along the V-shaped groove (37), the mounting plate (6) drives the disc (19) to rise through the lifting rod (20) slidably connected to its top. The rising of the disc (19) causes the internal space of the air cylinder (18) to become larger and the air pressure to become smaller, forming a negative pressure. Gas is inhaled through the air groove (22) opened in the fixed pipe (21) through the pipeline. Since the outer wall of the hose is in close contact with the inner wall of the fixed pipe (21), the fixed pipe (21) will generate a suction force on the hose at the air groove (22). As the mounting plate (6) rises, the suction force gradually increases, so that the hose will not be squeezed and deformed during the cutting process. The cutting motor (39) drives the cutting blade (3) and the grinding disc (5) to pass through the gap between the two fixed pipes (21) in sequence through the pulley (40) to cut and grind the hose. S3. After cutting and grinding are completed, the cutting motor (39) is turned off. The electric push rod (41) contracts to drive the mounting plate (6) to descend along the V-shaped groove (37) away from the track of the electric push rod (41) until it descends to the lowest point of the V-shaped groove (37). Then start the rotating motor (38). The rotating motor (38) drives the driving wheel (2) to rotate. The driving wheel (2) drives the hose to move, and the cut hose is extruded from the fixed pipe (21). The cut hose falls on the aggregate table (7). The rotating motor (38) drives the support plate (8) to rotate into the storage groove (42) through the driving assembly. The cut hose rolls down to the bottom end of the top surface of the aggregate table (7) along the inclined surface at the top of the aggregate table (7). The rotating motor (38) continues to drive the driving wheel (2) to rotate until when the hose moves a predetermined length, the support plate (8) just returns to its original position.
