[0031] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] When the UV-curing hose is produced, the product is a tubular product consisting of five parts from the inside to the outside: a reserved replacement rope, a bagged inner film, a glass fiber reinforced layer impregnated with resin, a bagged outer film, and a bagged UV protective film. During the production process, the factory often needs to cut the product to achieve specification production, and when the product is used to repair municipal pipelines, it needs to be cut according to the usage to reduce waste. When the UV-curing hose is cut, after the UV-curing hose is cut, the resin in the glass fiber reinforced layer impregnated with resin will leak out, which will pollute the environment on the one hand, and on the other hand, it will adhere to the tool. With the irradiation of external light, the resin adhered to the tool will solidify, which will make the tool blunt, thereby affecting the use of the tool. For this reason, the following solutions are proposed:

[0033] like Figures 1 to 6 As shown, a hose cutting device of the present invention comprises a mounting frame 1 and a cutting knife 2, an adjusting device 3 is arranged at the upper end of the mounting frame 1, a cutting assembly 4 is rotatably arranged at the side end of the adjusting device 3, the cutting knife 2 is located in the cutting assembly 4, the device is placed on the production and transportation line of the UV-curing hose with the assistance of the mounting frame 1, the cutting knife 2 is located at the upper end of the production and transportation line, when the UV-curing hose needs to be cut, the resin in the glass fiber reinforced layer of the UV-curing hose is rolled to both sides with the assistance of the adjusting device 3, so that the resin at the cutting position is reduced, thereby reducing the leakage of the resin, and then the cutting knife 2 is driven to descend with the assistance of the cutting assembly 4, thereby cutting the UV-curing hose.

[0034] The cutting assembly 4 includes a flattening roller 401, a blade 409 is provided at the lower end of the flattening roller 401 at a position corresponding to the cutting knife 2, a first slide groove 402 is provided at the side end of the flattening roller 401, a first slider 403 is slidably provided in the first slide groove 402, and the cutting knife 2 is arranged at the side end of the first slider 403. Before cutting, the UV-curing hose is reciprocatedly rolled with the assistance of the flattening roller 401, so that the resin in the glass fiber reinforced layer of the UV-curing hose in the cutting area is rolled to both sides, and then the first slider 403 slides down in the first slide groove 402, so that the cutting knife 2 extends downward from the blade 409, and then the cutting knife 2 cuts the UV-curing hose.

[0035] A driving hydraulic cylinder 414 is provided in the first slide groove 402, and the output end of the driving hydraulic cylinder 414 is connected to the first slider 403. After the driving hydraulic cylinder 414 is started, the output end of the driving hydraulic cylinder 414 will drive the lifting of the first slider 403. The driving hydraulic cylinder 414 provides power for the lifting of the first slider 403 with the assistance of the driving hydraulic cylinder 414, so that the lifting of the cutting knife 2 is stable and controllable.

[0036] The adjusting device 3 includes a lifting plate 301, a circular shaft 416 is arranged on the outside of the flattening roller 401, the circular shaft 416 is rotatably connected to the lifting plate 301, a through hole 302 is arranged above the circular shaft 416 of the lifting plate 301, a push plate 303 is arranged in the through hole 302 above the circular shaft 416, and a second damping cylinder 304 is arranged on both sides of the push plate 303 and connected to the lifting plate 301. The flattening roller 401 will be subjected to friction when it contacts the UV-curing hose. Therefore, when the flattening roller 401 rolls on the surface of the UV-curing hose, the flattening roller 401 will rotate, and then the resin in the glass fiber reinforced layer of the UV-curing hose to be cut area will be rolled to both sides, and after cutting the outer support, the flattening roller 401 is returned to its initial state with the assistance of the second damping cylinder 304.

[0037] A mounting plate 305 is provided at the lower end of the lifting plate 301, and the lifting plate 301 slides up and down in the mounting plate 305. A connecting pipe 306 is provided at the side end of the mounting plate 305, and a sliding seat 307 is provided at the lower end of the mounting plate 305. The connecting pipe 306 is connected to the pump body. With the assistance of the pump body, the liquid is input into the mounting plate 305 through the connecting pipe 306, thereby making the lifting plate 301 rise. When the pump body runs in reverse, the lifting plate 301 will fall.

[0038] The mounting frame 1 includes a support 101, a slide rail 308 is arranged on the upper end of the support 101, and the slide 307 slides on the slide rail 308, a cross frame 102 is arranged on the side end of the support 101, a matching block 309 is arranged on the lower end of the slide 307, and a motor 310 is arranged on the cross frame 102, and a rotating rod 311 is arranged on the output end of the motor 310, and the rotating rod 311 is rotationally matched with the support 101, and a reciprocating thread groove is arranged at the center of the rotating rod 311, and the rotating rod 311 is threadedly matched with the matching block 309. After the motor 310 is started, the output end of the motor 310 drives the rotating rod 311 to rotate, and the rotating rod 311 is threadedly matched with the matching block 309, and a reciprocating thread groove is arranged in the middle of the rotating rod 311, so that the matching block 309 will reciprocate, and the reciprocating movement of the matching block 309 will drive the slide 307 to reciprocate on the slide rail 308.

[0039] Second sliders 404 are slidably arranged on the flattening roller 401 on both sides of the first slider 403, and an L-shaped groove is arranged on the side of the second slider 404 close to the first slider 403. A grinding sheet 405 is arranged on the side end of the second slider 404 through a torsion spring rotation, and the grinding sheet 405 is attached to the side end of the cutting knife 2. When the second slider 404 moves up and down, the second slider 404 will drive the lifting of the grinding sheet 405, and the grinding sheet 405 is arranged on the side end of the second slider 404 through a torsion spring rotation. Therefore, when the grinding sheet 405 is lifted or lowered, it will be attached to the outside of the cutting knife 2 for grinding, so that the cutting knife 2 remains sharp and the cutting stability of the cutting knife 2 is ensured.

[0040] A third slider 406 is slidably provided on the flattening roller 401 at the lower end of the second slider 404, a pressure rod 407 is provided at the lower end of the third slider 406, an opening 410 is provided at the lower end of the flattening roller 401 at a position corresponding to the pressure rod 407, a pressure ball 411 is provided on the side of the pressure rod 407 extending out of the opening 410, and when the third slider 406 descends, the pressure rod 407 will extend out of the opening 410, so that the pressure ball 411 is pressed on the surface of the UV curing hose, and the pressure balls 411 on both sides press on the UV curing hose, which will make the UV curing hose tighten, which is conducive to smooth cutting.

[0041] A spring 408 is arranged between the third slider 406 and the flattening roller 401 on the outside of the pressure rod 407. The third slider 406 and the second slider 404 are wedge-fitted. A pressure sensor is arranged on the outside of the flattening roller 401. When the third slider 406 moves, it will drive the second slider 404 to rise and fall. Correspondingly, the rise and fall of the second slider 404 can also move the third slider 406. With the assistance of the spring 408, it is ensured that the third slider 406 will not move arbitrarily due to the action of gravity, thereby ensuring the stability of the equipment. The pressure sensor can detect the pressure between the flattening roller 401 and the UV curing hose.

[0042] A second slide groove 412 is provided on the inner side of the flattening roller 401 at a position corresponding to the second slider 404, and the second slider 404 slides and is limited in the second slide groove 412. A third slide groove 413 is provided on the side end of the flattening roller 401 at a position corresponding to the third slider 406, and the third slider 406 slides and is limited in the third slide groove 413. When the second slider 404 moves, it is limited by the second slide groove 412. When the third slider 406 moves, it is limited by the third slide groove 413, so that the equipment is more stable during use.

[0043] A first damping cylinder 415 is provided at the inner top of the second slide groove 412 , and the lower end of the first damping cylinder 415 is connected to the second slider 404 . The first damping cylinder 415 is used to prevent the second slider 404 from being displaced due to gravity, thereby ensuring the stability of the second slider 404 .

[0044] A groove is provided at the lower end of the grinding sheet 405, and the lower ends of the two grinding sheets 405 are staggered with the aid of the groove. The side of the grinding sheet 405 close to the cutting knife 2 matches the shape of the cutting knife 2, and the lower ends of the two grinding sheets 405 can be staggered and overlapped, thereby completely wrapping the blade part of the cutting knife 2. Therefore, when the grinding sheet 405 moves up and down, the blade of the cutting knife 2 can be polished to ensure the sharpness of the blade of the cutting knife 2.

[0045] During the use of the present invention, the UV-curing hose will be transported on the production and transportation line after it is produced. After the production of the UV-curing hose reaches the specifications, the UV-curing hose needs to be cut. At this time, the production line stops and the motor 310 is started. The output end of the motor 310 drives the rotation of the rotating rod 311. The rotation of the rotating rod 311 is threadedly matched with the matching block 309 through the reciprocating thread groove, so that the matching block 309 reciprocates. When the matching block 309 reciprocates, the reciprocating movement of the flattening roller 401 is driven by the lifting plate 301 and the round shaft 416 and other components.

[0046] During the reciprocating movement of the flattening roller 401, the pump body is operated in the reverse direction, thereby lowering the lifting plate 301, and the lifting plate 301 is retracted into the mounting plate 305. By controlling the pump body, the descending distance of the lifting plate 301 can be accurately controlled. As the lifting plate 301 descends, the flattening roller 401 will also descend. The flattening roller 401 will gradually press on the UV-curing hose on the production line, thereby increasing the detection value of the pressure sensor. When the detection value of the pressure sensor reaches the threshold value b, the pump body stops operating, thereby stopping the flattening roller 401 from descending.

[0047] As the flattening roller 401 gradually descends and contacts the UV-curing hose, as the flattening roller 401 reciprocates, the flattening roller 401 first scrapes the impurities on the surface of the UV-curing hose to both sides, ensuring that the surface of the cutting area of ​​the UV-curing hose is cleaner, thereby ensuring smooth cutting.

[0048] Then, as the flattening roller 401 moves back and forth, the flattening roller 401 will roll the UV-curing hose, so that the resin in the glass fiber reinforced layer in the cutting area of ​​the UV-curing hose is rolled to both sides, reducing the leakage of the resin in the glass fiber reinforced layer during the cutting process of the cutting knife 2, and reducing the amount of resin adhering to the cutting knife 2.

[0049] In the process of the flattening roller 401 reciprocating and rolling the UV curing hose, the flattening roller 401 will rotate, and as the flattening roller 401 rotates, when the pressing ball 411 contacts the UV curing hose, the pressing ball 411 will be pressed into the opening 410, and the movement of the pressing ball 411, with the assistance of the pressing rod 407, causes the third slider 406 to move toward the second slider 404, and the movement of the third slider 406 will enter the through groove 417, and when the movement of the third slider 406 contacts the second slider 404, as the third slider 406 moves, the third slider 406 will move into the through groove 417. The slider 406 moves, and the second slider 404 moves upward. When the second slider 404 moves upward, the grinding sheet 405 moves upward. The grinding sheet 405 is rotatably connected to the second slider 404 and is provided with a torsion spring. Therefore, when the grinding sheet 405 moves upward, it will stick to the cutting knife 2 for grinding, and with the reciprocating movement of the flattening roller 401, the grinding sheets 405 on both sides of the cutting knife 2 move upward alternately, so that the cutting knife 2 can ensure the grinding effect before cutting, so that the cutting knife 2 can cut smoothly.

[0050] As the flattening roller 401 reciprocates, the detection value of the pressure sensor will gradually decrease. When the detection value of the pressure sensor decreases to the threshold value a, the pump body will continue to operate, causing the lifting plate 301 to drop again, and then the flattening roller 401 will continue to drop, and then the above process will be repeated again.

[0051] When repeating the above process, if the detection value of the pressure sensor is constant between the threshold value a and the threshold value b as the flattening roller 401 reciprocates, it indicates that the resin in the glass fiber reinforced layer in the cutting area of ​​the UV-curable hose has been completely rolled to both sides. At this time, by precisely controlling the operation of the motor 310, the pressure in the second damping cylinder 304 on both sides of the push plate 303 is made the same, even if the cutting knife 2 remains in a vertical state.

[0052] Start the driving hydraulic cylinder 414, and the output end of the driving hydraulic cylinder 414 will drive the first slider 403 to descend, thereby causing the cutting knife 2 to descend. The descending cutting knife 2 will push open the grinding plates 405 on both sides, so that the lower blade of the cutting knife 2 extends out from between the two grinding plates 405. In the process of the cutting knife 2 extending out from between the two grinding plates 405, the two grinding plates 405 work together to grind the cutting knife 2.

[0053] As the first slider 403 descends, with the assistance of the L-shaped groove at the side end of the second slider 404, the first slider 403 will push the second slider 404 down, and when the second slider 404 descends and contacts the third slider 406, the third slider 406 will move along the third slide groove 413 toward the direction close to the UV curing hose, thereby pressing the pressure ball 411 on the surface of the UV curing hose. As the first slider 403 continues to descend, the pressure balls 411 on both sides of the cutting knife 2 will gradually stretch and tighten the UV curing hose to both sides, and at the same time, the cutting knife 2 cuts the tightened UV curing hose to ensure smooth cutting of the UV curing hose by the cutting knife 2.

[0054] After the cutting is completed, the hydraulic cylinder 414 is driven to return to the initial state. With the assistance of the spring 408 and the first damping cylinder 415, the third slider 406 and the second slider 404 will return to the initial state, and the pump body is controlled to operate so that the lifting plate 301 rises to the limit. When the lifting plate 301 rises to the limit, the production line of the UV curing hose starts to operate again.

[0055] The main functions of the present invention are as follows: by setting components such as a pressure sensor, a flattening roller 401, a pressure ball 411 and a grinding sheet 405, when it is necessary to cut the UV-curable hose, the pump body and the motor 310 are controlled to make the flattening roller 401 descend and reciprocate, so that the flattening roller 401 reciprocates and grinds the cutting area of ​​the UV-curable hose, and the pressure sensor can be used to determine the grinding condition of the UV-curable hose, and the flattening roller 401 descends and reciprocates to grind the UV-curable hose. During the rolling process, with the assistance of components such as the pressure ball 411 and the pressure rod 407, the grinding sheet 405 can grind the cutting knife 2, and the reciprocating movement of the flattening roller 401 can also clean the surface of the cutting area of ​​the UV-curing hose. When the cutting knife 2 descends to cut, on the one hand, the grinding sheets 405 on both sides work together to grind the cutting knife 2, and on the other hand, the pressure ball 411 applies force to both sides of the cutting area of ​​the UV-curing hose to tighten the UV-curing hose, ensuring smooth cutting by the cutting knife 2.

[0056] The present invention also provides an application of a hose cutting device in the production of ultraviolet light-curing hoses. During the production of ultraviolet light-curing hoses, the hose cutting device is used to cut the produced ultraviolet light-curing hoses according to length specifications.
