[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 This utility model provides a cutting device for processing fuel hoses, including a frame 1, a roller frame 3 placed on the ground on one side of the frame 1, and a rolled fuel hose 4 on the roller frame 3. In this embodiment, the rolled fuel hose 4 is mounted on the idler roller frame 3. The rotation of the idler roller frame 3 can be used to release the fuel hose 4 and realize continuous cutting of the fuel hose 4.

[0018] Please see Figure 1 and Figure 4 One end of the frame 1 is provided with a lifting mechanism 5 with a sleeve structure. The lifting mechanism 5 is used to drive the cutting module 6 to move up and down. The lifting mechanism 5 includes guide seats 51 fixedly installed on the outer walls of both sides of the frame 1. A lifting frame 52 sleeved on the outside of the frame 1 is slidably inserted into the guide seats 51. A lead screw 55 is provided at the bottom of the lifting frame 52. A support frame 54 fixed on one side of the lead screw 55 is provided at the bottom end of the lead screw 55. A reduction gearbox 56 is provided at the top of the lead screw 55. A lifting motor 57 is provided on one side of the reduction gearbox 56. Both the reduction gearbox 56 and the lifting motor 57 are installed below the platform on the frame 1.

[0019] In this embodiment, the lifting mechanism 5 is used to realize the upward and downward movement of the cutting module 6. When the lifting mechanism 5 drives the cutting module 6 to descend, the cutting operation of the fuel hose 4 is realized. Specifically, the lifting motor 57 is started, which drives the reduction gearbox 56 to run, and then drives the lead screw 55 to rotate. The lead screw 55 drives the lifting frame 52 to move up and down inside the guide seat 51. The lifting frame 52 drives the cutting module 6 to move up and down.

[0020] Please see Figure 1 and Figure 4 A cutting module 6 is fixedly installed on the top of the lifting mechanism 5; the cutting module 6 includes a drive motor 61, a motor base 53 is fixedly installed on the top of the lifting frame 52, and the drive motor 61 is fixed inside the motor base 53. A cutting blade 62 is installed at the output end of the drive motor 61, and a protective cover 63 fixed on the drive motor 61 is installed on the outside of the cutting blade 62.

[0021] In this embodiment, starting the drive motor 61 can drive the cutting blade 62 to rotate at high speed, thereby realizing the cutting operation of the fuel hose 4. The protective cover 63 protects the cutting blade 62 and prevents the cutting blade 62 from injuring the operator.

[0022] Please see Figure 1 and Figure 5 A head assembly 7 is fixedly installed on one end of the frame 1. The head assembly 7 is used to limit the free end of the fuel hose 4. The head assembly 7 includes a card holder 71 fixedly installed on the top of the frame 1. Connecting ears 72 are provided on both outer walls of the card holder 71. A cover 73 is provided on one side of the top of the card holder 71. The fuel hose 4 is inserted into the hole between the card holder 71 and the cover 73, and the fuel hose 4 is fitted with the hole with a clearance fit.

[0023] In this embodiment, the fuel hose 4 slides within the retainer 71 and the cover 73, thereby enabling the fuel hose 4 to be pulled out. At the same time, the retainer 71 and the cover 73 can limit the free end of the fuel hose 4, making it easier for the traction mechanism 8 to clamp the free end of the fuel hose 4.

[0024] Please see Figure 1 and Figure 2 A traction mechanism 8 is provided above the frame 1. The traction mechanism 8 is used to stretch and measure the fuel hose 4. The traction mechanism 8 includes a guide rail 82, a rack 83 and a grating ruler 84 fixed above the frame 1. A sliding seat 81 is slidably installed above the guide rail 82. A connecting frame 88 is fixedly installed on one side of the sliding seat 81. A servo motor 87 with a gap between it and the grating ruler 84 is provided below the connecting frame 88. A traveling gear 86 is installed on the output shaft of the servo motor 87. The traveling gear 86 meshes with the rack 83. A bearing seat is provided on one side of the traveling gear 86, and a limiting frame 85 is slidably connected to the rack 83 below the bearing seat.

[0025] In this embodiment, after the traction mechanism 8 is started, the servo motor 87 drives the walking gear 86 to rotate. The walking gear 86 meshes with the rack 83, causing the walking gear 86 to move on the rack 83, thereby driving the servo motor 87 and the sliding seat 81 to move. The sliding seat 81 moves linearly on the guide rail 82. A grating reading head is set below the servo motor 87. By using the grating reading head to illuminate the grating ruler 84, the moving distance of the servo motor 87 can be accurately calculated, thereby realizing the accurate extraction and measurement of the fuel hose 4, and achieving the purpose of cutting the fuel hose 4 to a fixed length. It should be noted that the grating reading head and grating ruler 84 set below the servo motor 87 are both structures commonly used in existing servo machine tools, capable of precise displacement. The specific structure and measurement principle of the grating reading head and grating ruler 84 are existing publicly available technologies, and will not be described in detail here.

[0026] Please see Figure 1 and Figure 3 Both the traction mechanism 8 and the toggle assembly 7 are equipped with a pressing mechanism 9. The pressing mechanism 9 is used to fix the fuel hose 4 on the traction mechanism 8 and the toggle assembly 7. The pressing mechanism 9 includes a mounting base 92 installed on one side of the traction mechanism 8 and the toggle assembly 7. An actuator 91 is fixedly installed on the mounting base 92. The actuator 91 can adopt an existing cylinder structure. A telescopic rod 93 is provided above the actuator 91. An ear seat 94 is fixedly installed on one side of the top end of the telescopic rod 93, and a pressure roller 95 is fixedly installed at one end of the ear seat 94.

[0027] In this embodiment, when the traction mechanism 8 is used to pull the fuel hose 4, the pressing mechanism 9 on the head assembly 7 moves upward, releasing the fuel hose 4 from the head assembly 7. The pressing mechanism 9 then acts to clamp and fix the free end of the fuel hose 4. Specifically, the driver 91 is activated, which drives the telescopic rod 93 and the ear seat 94 to descend, thereby driving the pressure roller 95 to press only on the fuel hose 4, fixing the fuel hose 4 at the sliding seat 81. Thus, the traction mechanism 8 is used to pull the fuel hose 4. After the fuel hose 4 is pulled into place by the traction mechanism 8, the pressing mechanism 9 on the head assembly 7 acts to fix the fuel hose 4 on the head assembly 7.

[0028] Please see Figure 1 A storage box 2 is provided on one side of the frame 1. The storage box 2 is used to store the fuel hose 4 after it has been cut. The storage box 2 has various specifications, which need to be determined according to the length of the cut fuel hose 4.

[0029] In this embodiment, the fuel hose 4 after cutting is temporarily stored inside the storage box 2 to facilitate the subsequent transportation and use of the fuel hose 4.

[0030] The working principle and usage process of this utility model are as follows: First, the operator installs the rolled fuel hose 4 on the roller frame 3. When the fuel hose 4 is stretched, the rolled fuel hose 4 can be rotated and unfolded on the roller frame 3 to realize the unloading of the fuel hose 4. The free end of the fuel hose 4 passes through the inside of the bundle head assembly 7 and is exposed for a distance of one to two centimeters. Next, the traction mechanism 8 is activated, causing the servo motor 87 to drive the travel gear 86 to rotate. The travel gear 86 moves on the rack 83, thereby driving the sliding seat 81 to move linearly on the guide rail 82, so that one end of the sliding seat 81 is close to the free end of the fuel hose 4. The pressing mechanism 9 is used to fix and clamp the free end of the fuel hose 4 inside the sliding seat 81. By using the grating reading head to illuminate the grating ruler 84, the moving distance of the servo motor 87 can be accurately calculated. After the pulling distance of the fuel hose 4 meets the preset requirements, the servo motor 87 stops. At this time, the lifting mechanism 5 is activated, which can drive the cutting module 6 to descend. The drive motor 61 drives the cutting blade 62 to cut the fuel hose 4. After the fuel hose 4 is cut, the operator removes the fuel hose 4 from the frame 1 and puts it into the storage box 2. The traction mechanism 8 quickly returns and cuts the fuel hose 4 again, which greatly improves the cutting efficiency of the fuel hose 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
