Description

Technical Field

[0001] This invention relates to the field of hose production technology, specifically a hose production device with surface cleaning function. Background Technology

[0002] Rubber hoses are mainly composed of an inner rubber layer, multiple layers of steel wire winding, and an outer rubber layer. The inner rubber layer allows the conveyed medium to withstand pressure and protects the steel wire from corrosion. The outer rubber layer protects the steel wire from damage, and the steel wire winding layer acts as a skeleton material to reinforce the entire hose.

[0003] During the production of rubber hoses, an oxide layer forms on the surface, adhering to both the inner and outer rubber layers. While the oxide layer on the outer layer is relatively easy to clean, the oxide layer on the inner layer is difficult to remove. Existing rubber hose production equipment cannot simultaneously clean the inner and outer surfaces of the hose during production. Post-production cleaning requires significant effort, impacting production efficiency and increasing costs. Summary of the Invention

[0004] The purpose of this invention is to provide a hose production apparatus with surface cleaning function to solve the problems mentioned in the background art.

[0010] As a further embodiment of the present invention: the end positioning component includes a positioning semicircular frame and a fastening frame, which are connected by bolts. The positioning semicircular frame and the fastening frame are symmetrically arranged on both sides of the hose. Each side of the positioning semicircular frame is provided with a connecting post one and a connecting post two. A support post is provided on the frame corresponding to the position of the connecting post one. The top of the support post is rotatably installed with the connecting post one, and the bottom of the support post is rotatably installed with the connecting post two. A linkage rod is provided between the connecting posts two at both ends of the outer wrapping component.

[0011] As a further embodiment of the present invention: a positioning ball is engaged between the positioning semicircular frame and the fastening frame, and the positioning ball is in contact with the outer adhesive layer surface of the tubing.

[0012] As a further embodiment of the present invention: the outer wrapping component includes symmetrically arranged semi-circular wrapping frames, each semi-circular wrapping frame having a plurality of magnetic strips corresponding to the adsorption magnet, and the semi-circular wrapping frame having a connecting flange, the two sides of the semi-circular wrapping frames being fixedly installed together by the connecting flange and bolts.

[0013] As a further embodiment of the present invention: the rotary drive assembly includes an annular connecting groove disposed on the side of the fastening frame, a plurality of mating wheels are evenly disposed in the annular connecting groove, a fixing rod is connected to the mating wheel, a mating groove is disposed at the end of the semi-circular wrapping frame, a gear ring is sleeved on the edge of the semi-circular wrapping frame, a mating protrusion is disposed on the inner ring of the gear ring, the mating protrusion and the mating groove cooperate with each other, a fixing ring is disposed at the end of the semi-circular wrapping frame, the fixing rod passes through the gear ring and is fixedly installed by a nut, a drive motor is fixedly installed on the fastening frame, the drive motor is connected to a drive gear, and the drive gear meshes with the gear ring.

[0014] As a further embodiment of the present invention: the external cleaning mechanism includes a cooling water tank, a suction pump and a cooling water pipe are installed inside the cooling water tank, the cooling water pipe is connected to a semi-circular spray frame, a drain pipe is installed at the bottom of the cooling water tank, two sets of positioning wheels are installed on the side wall of the cooling water tank, the rubber hose passes through the semi-circular spray frame and the positioning wheels, the cooling water tank is symmetrically provided with mounting frames on the upper and lower sides of the rubber hose, a wrapping scraper is connected to the mounting frame, the wrapping scraper points in the opposite direction of the movement of the rubber hose, and an absorbent sponge is provided at the end of the wrapping scraper.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The outer cleaning mechanism cleans the oxide layer on the outer surface of the hose. Then, the guide wheel controls the hose to be recessed downwards. The recessed part is filled with cleaning fluid. The inner cleaning mechanism cleans the oxide layer on the inner surface of the hose. Due to the trapezoidal routing, the cleaning fluid always stays in the recessed part, continuously cleaning the inner surface of the hose. When cleaning the inner surface of the hose, the cleaning component is inserted into the hose in advance and controlled to stay in the recessed part of the hose. At this time, the outer wrapping component, the end positioning component and the rotary drive component are installed in sequence with the frame. The outer wrapping component adsorbs the cleaning component, and the end positioning component positions the hose at both ends of the recessed part, so that the rotary drive component can rotate on the outer ring of the hose, thereby driving the cleaning component inside the hose to rotate and clean the inner surface of the hose.

[0017] (2) When the connecting rod and the opening frame are combined with the intermediate frame, the outer wrapping component and the adsorption magnet are attracted to each other, which will drive the opening frame to open outward. At this time, the sliding sleeve moves closer to each other, driving the plug-in column to move. The truncated cone at the end of the plug-in column is squeezed towards the opening slope, thereby squeezing the cleaning brush against the opening slope, so that the cleaning brush opens outward and contacts the inner surface of the hose.

[0018] (3) When the outer packaging component is separated from the outer surface of the hose, the opening frame returns to the position close to the middle frame under the action of the support spring. The plug-in column drives the truncated frame to separate from the opening slope. After the cleaning brush is separated from the squeezing action of the truncated frame, it returns to the initial installation state. The initial installation angle of the cleaning brush is parallel to the middle frame. At this time, it is convenient to remove the cleaning component from the end of the hose.

[0019] (4) A cylindrical structure is formed by two semi-circular wrapping frames. Multiple magnetic strips are set for the adsorption magnets in the cleaning component. The advantage of setting magnetic strips is that the adsorption range of the cleaning component can be expanded. When the cleaning component encounters a small obstacle, it can combine its own rotation to get rid of the defect and continuously clean the oxide layer on the inner surface of the tubing with the cleaning fluid.

Detailed Implementation

[0031] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0032] like Figure 1 As shown, a rubber hose production device with surface cleaning function includes an extruder 1, a wire winding machine, and an outer rubber coating machine. The rubber hose 10 processed by the extruder 1, the wire winding machine, and the outer rubber coating machine passes through an outer cleaning mechanism 2. The rubber hose 10 is positioned and installed on a frame. The frame is provided with multiple guide wheels 11. After passing through the guide wheels 11, the rubber hose 10 is arranged in an inverted trapezoidal shape with a downward concave shape. An inner cleaning mechanism 3 is connected to the concave part of the rubber hose 10.

[0033] like Figure 2 , Figure 3As shown, the internal cleaning mechanism 3 includes a cleaning component 33 pre-placed inside the hose 10. The cleaning component 33 is horizontally positioned in the recessed area along with the hose 10. The hose 10 is filled with cleaning fluid in the recessed area. An outer wrapping component 30 is sleeved on the outside of the hose 10. The outer wrapping component 30 and the cleaning component 33 are mutually attracted. End positioning components 31 are rotatably connected to both ends of the outer wrapping component 30. The end positioning components 31 are fixedly installed between the end positioning components 31 and the outer wrapping component 30. A rotation drive component 32 is provided between the end positioning components 31 and the outer wrapping component 30. The outer wrapping component 30 drives the cleaning component 33 to rotate inside the hose 10 through the rotation drive component 32 and cleans the inside of the hose 10.

[0034] Specifically, the rubber hose 10 consists of an inner rubber layer, multiple layers of steel wire winding, and an outer rubber layer. The main body of the production equipment for the rubber hose 10 is formed by an extruder 1, a steel wire winding machine, and an outer rubber layer wrapping machine. After initially obtaining the finished rubber hose 10, the oxide layer on the outer surface of the rubber hose 10 is first cleaned using the outer cleaning mechanism 2. Then, the guide wheel 11 controls the rubber hose 10 to curve downwards into a concave shape. Cleaning fluid is filled into the concave area, and the oxide layer on the inner surface of the rubber hose 10 is cleaned using the inner cleaning mechanism 3. Due to the inverted trapezoidal curve design, the cleaning fluid remains in the concave area, continuously cleaning the inner surface of the rubber hose 10.

[0035] More specifically, when cleaning the inner surface of the hose 10, the cleaning component 33 is inserted into the hose 10 in advance, and the cleaning component 33 is controlled to stay in the recessed part of the hose 10. At this time, the outer wrapping component 30, the end positioning component 31 and the rotary drive component 32 are installed in sequence with the frame. The outer wrapping component 30 adsorbs the cleaning component 33, and the end positioning component 31 positions the hose 10 at both ends of the recessed part, so that the rotary drive component 32 can rotate on the outer ring of the hose 10, thereby driving the cleaning component 33 inside the hose 10 to rotate and clean the inner surface of the hose 10.

[0036] Furthermore, such as Figure 4 , Figure 5As shown, the cleaning component 33 includes an intermediate frame 330, on which two sets of mating sleeves 333 are fitted. Multiple connecting rods 334 are rotatably mounted on the two sets of mating sleeves 333. An opening frame 335 is rotatably connected to the end of each connecting rod 334. An adsorption magnet 337 is fixedly mounted on the opening frame 335. Terminals 331 are provided at both ends of the intermediate frame 330. Multiple insertion posts 3311 are annularly inserted into each terminal 331. One end of each insertion post 3311 is connected to a mating sleeve 333, and the other end of each insertion post 3311 is connected to a frustum-shaped frame. 3312, the terminal 331 is provided with an opening inclined surface 3314 on the side facing the truncated cone 3312, and a plurality of cleaning brushes 332 are evenly arranged in the inner ring of the opening inclined surface 3314. The truncated cone 3312 is provided with an inclined groove 3313 corresponding to the cleaning brushes 332. When the truncated cone 3312 moves with the insertion post 3311 and the sliding sleeve 333, it squeezes the cleaning brushes 332 and pushes the cleaning brushes 332 onto the opening inclined surface 3314. The outer wrapping component 30 is driven by the rotation drive component 32 and attracts the adsorption magnet 337 to drive the cleaning component 33 to rotate as a whole.

[0037] Specifically, in order to facilitate the entry and exit of the cleaning component 33 into the tubing 10, and to ensure reliable contact with the inner wall of the tubing 10 during cleaning to remove the oxide layer adhering to the inner wall, a connecting rod 334 and an opening frame 335 are provided in conjunction with the intermediate frame 330. When the outer wrapping component 30 and the adsorption magnet 337 attract each other, the opening frame 335 will open outward. At this time, the sliding sleeve 333 moves closer to each other, causing the insertion post 3311 to move. The frustum frame 3312 at the end of the insertion post 3311 is pressed towards the opening slope 3314, thereby squeezing the cleaning brush 332 against the opening slope 3314, so that the cleaning brush 332 opens outward and contacts the inner surface of the tubing 10.

[0038] Furthermore, such as Figure 4 , Figure 5 As shown, the intermediate frame 330 is provided with multiple mating grooves 338, and the mating sleeve 333 is provided with mating protrusions 3310 corresponding to the mating grooves 338. The opening frame 335 has contact balls 336 engaged on both sides of the adsorption magnet 337. A support spring 339 is provided between the two sets of mating sleeves 333. The intermediate frame 330, the terminal 331 and the frustum frame 3312 are hollowed out in the center.

[0039] Specifically, when the outer casing 30 is disengaged from the outer surface of the hose 10, the opening frame 335 returns to a position close to the intermediate frame 330 under the action of the support spring 339. The plug post 3311 drives the truncated cone frame 3312 to disengage from the opening ramp 3314. After the cleaning brush 332 is freed from the squeezing action of the truncated cone frame 3312, it returns to its initial installation state. The initial installation angle of the cleaning brush 332 is parallel to the intermediate frame 330, which makes it easy to remove the cleaning component 33 from the end of the hose 10.

[0040] It should be noted that the downward-recessed trapezoidal design of the hose 10 not only facilitates the storage of cleaning fluid, but also, combined with the guide wheel 11 forming angles at both ends of the recessed area, allows the hose 10 to engage with the cleaning component 33 during production if there are significant protrusions on its inner wall. This causes the cleaning component 33 to move and detach from the outer casing component 30, eliminating cleaning noise. This effect can be used to detect inner wall defects during hose 10 production. Once detached from the outer casing component 30, the cleaning brush 332 in the cleaning component 33 returns to its initial installation state and detaches from the inner wall of the hose 10, preventing the hose 10 from stopping and avoiding interference with the extruder 1 at the front end. Operators only need to mark the outer wall of the hose 10 when the cleaning component 33 detaches, and then proceed with defect treatment.

[0041] Furthermore, such as Figure 6 , Figure 7 , Figure 8 As shown, the end positioning component 31 includes a positioning semicircular frame 310 and a fastening frame 311. The positioning semicircular frame 310 and the fastening frame 311 are connected by bolts. The positioning semicircular frame 310 and the fastening frame 311 are symmetrically arranged on both sides of the hose line 10. Each side of the positioning semicircular frame 310 is provided with a connecting post 1 313 and a connecting post 2 314. A support post 315 is provided on the frame at the position corresponding to the connecting post 1 313. The top of the support post 315 is rotatably installed between the connecting post 1 313 and the bottom of the support post 315 is rotatably installed between the connecting post 2 314. A linkage rod 317 is provided between the connecting posts 2 314 at both ends of the outer wrapping component 30.

[0042] Specifically, in order to facilitate the reliable rotation of the outer wrapping component 30 around the outer ring of the hose 10 under the drive of the rotation drive component 32, the two ends of the hose 10 are clamped and positioned by the positioning semicircular frame 310 and the fastening frame 311. By setting the connecting column 1 313 and connecting column 2 314 on the positioning semicircular frame 310, and using the support column 315 and the telescopic motor 316 to form a quadrilateral structure, the positioning semicircular frame 310 and the fastening frame 311 on both sides are controlled to open and close, thereby facilitating the positioning and clamping of the outer wall of the hose 10.

[0043] Furthermore, such as Figure 7 , Figure 8 As shown, a positioning ball 312 is engaged between the positioning semicircular frame 310 and the fastening frame 311, and the positioning ball 312 is in contact with the outer adhesive layer surface of the tubing 10.

[0044] Specifically, in order to further reduce the resistance of the outer wrapping component 30 to the tubing 10, a positioning ball 312 is provided between the positioning semicircular frame 310 and the fastening frame 311. When the tubing 10 moves forward, rolling friction occurs between it and the positioning ball 312, reducing the wear on the surface of the tubing 10.

[0045] Furthermore, such as Figure 6 As shown, the outer wrapping component 30 includes symmetrically arranged semi-circular wrapping frames 300. Multiple magnet strips 301 are provided inside the semi-circular wrapping frames 300 corresponding to the adsorption magnets 337. A connecting flange 302 is provided on the semi-circular wrapping frames 300. The two semi-circular wrapping frames 300 on both sides are fixedly installed together by the connecting flange 302 and bolts.

[0046] Specifically, a cylindrical structure is formed by two semi-circular wrapping frames 300, and multiple magnetic strips 301 are set in the corresponding adsorption magnets 337 inside the cleaning component 33. The advantage of setting magnetic strips 301 is that it can expand the adsorption range of the cleaning component 33. When the cleaning component 33 encounters a small obstacle, it can combine its own rotation to get rid of the defect, thereby working with the cleaning fluid to continuously clean the oxide layer on the inner surface of the hose 10.

[0047] Furthermore, such as Figure 6 , Figure 7As shown, the rotary drive assembly 32 includes an annular connecting groove 326 disposed on the side of the fastening frame 311. Multiple mating wheels 320 are evenly arranged within the annular connecting groove 326. A fixing rod 321 is connected to each mating wheel 320. A mating groove 323 is provided at the end of the semi-circular wrapping frame 300. A gear ring 322 is fitted around the edge of the semi-circular wrapping frame 300. A mating protrusion 324 is provided on the inner ring of the gear ring 322. The mating protrusion 324 and the mating groove 323 engage with each other. A fixing ring 327 is provided at the end of the semi-circular wrapping frame 300. The fixing rod 321 passes through the gear ring 322 and is fixedly installed with a nut. A drive motor 328 is fixedly installed on the fastening frame 311. The drive motor 328 is connected to a drive gear 325, which meshes with the gear ring 322.

[0048] Specifically, the outer wrapping component 30, together with the gear ring 322, the fixing rod 321, and the mating wheel 320, is rotatably mounted on the side of the fastening frame 311. The advantage of installing the outer wrapping component 30 in this way is that the semi-circular wrapping frame 300 will not exert force on the outer wall of the hose 10, reducing wear on the outer surface of the hose 10. The gear ring 322 and the outer wrapping component 30 are rotated by the drive motor 328 and the drive gear 325. The above structure facilitates the disassembly and assembly of the outer wrapping component 30, the rotation drive component 32, and the end positioning component 31, realizing the rapid assembly and cleaning operation of the inner cleaning mechanism 3 and the hose 10.

[0049] Furthermore, such as Figure 9 , Figure 10 As shown, the external cleaning mechanism 2 includes a cooling water tank 20, a suction pump and a cooling water pipe 21 are installed inside the cooling water tank 20, the cooling water pipe 21 is connected to a semi-circular spray frame 22, a drain pipe 23 is installed at the bottom of the cooling water tank 20, two sets of positioning wheels 24 are installed on the side wall of the cooling water tank 20, the rubber hose 10 passes through the semi-circular spray frame 22 and the positioning wheels 24, the cooling water tank 20 is symmetrically provided with mounting brackets 27 on the upper and lower sides of the rubber hose 10, a wrapping scraper 25 is connected to the mounting bracket 27, the wrapping scraper 25 points in the opposite direction of the movement of the rubber hose 10, and an absorbent sponge 26 is provided at the end of the wrapping scraper 25.

[0050] Specifically, cooling water is continuously sprayed onto the surface of the hose 10 by the semi-circular sprayer 22 to reduce the temperature of the hose 10 and harden the oxide layer on the outer surface. The oxide layer is then scraped off by the wrapping scraper 25, and finally the surface of the hose 10 is wiped with the absorbent sponge 26.

[0051] The working principle of this invention embodiment is as follows:

[0052] like Figures 1-10As shown, the outer cleaning mechanism 2 cleans the oxide layer on the outer surface of the hose 10. Then, the guide wheel 11 controls the hose 10 to be recessed downwards, and cleaning fluid is filled into the recessed area. The inner cleaning mechanism 3 cleans the oxide layer on the inner surface of the hose 10. Due to the inverted trapezoidal routing, the cleaning fluid always stays in the recessed area, continuously cleaning the inner surface of the hose 10. When cleaning the inner surface of the hose 10, the cleaning component 33 is inserted into the hose 10 in advance and controlled to stay in the recessed area of ​​the hose 10. At this time, the outer wrapping component 30, the end positioning component 31, and the rotary drive component 32 are installed in sequence with the frame. The outer wrapping component 30 adsorbs the cleaning component 33, and the end positioning component 31 positions the hose 10 at both ends of the recessed area, so that the rotary drive component 32 can rotate on the outer ring of the hose 10, thereby driving the cleaning component 33 inside the hose 10 to rotate and clean the inner surface of the hose 10. The intermediate frame 330 is equipped with a connecting rod 334 and an opening frame 335. When the outer wrapping component 30 and the adsorption magnet 337 are attracted to each other, the opening frame 335 will open outward. At this time, the sliding sleeve 333 moves closer to each other, causing the insertion post 3311 to move. The truncated cone 3312 at the end of the insertion post 3311 is pressed towards the opening slope 3314, thereby pressing the cleaning brush 332 against the opening slope 3314, so that the cleaning brush 332 opens outward and contacts the inner surface of the tubing 10. When the outer wrapping component 30 is detached from the outer surface of the hose 10, the opening frame 335 returns to a position close to the intermediate frame 330 under the action of the support spring 339. The insertion post 3311 drives the truncated cone frame 3312 to disengage from the opening ramp 3314. After the cleaning brush 332 is freed from the squeezing action of the truncated cone frame 3312, it returns to its initial installation state. The initial installation angle of the cleaning brush 332 is parallel to the intermediate frame 330, which facilitates the removal of the cleaning component 33 from the end of the hose 10. The two semi-circular wrapping frames 300 form a cylindrical structure. Multiple magnetic strips 301 are set corresponding to the adsorption magnet 337 inside the cleaning component 33. The advantage of setting the magnetic strips 301 is that it can expand the adsorption range of the cleaning component 33. When the cleaning component 33 encounters a small obstacle, it can disengage from the defect by combining its own rotation. With the help of the cleaning fluid, the oxide layer is continuously cleaned from the inner surface of the hose 10. The outer wrapping component 30, together with the gear ring 322, the fixing rod 321, and the mating wheel 320, is rotatably mounted on the side of the fastening frame 311. The advantage of installing the outer wrapping component 30 in this way is that the semi-circular wrapping frame 300 will not exert force on the outer wall of the hose 10, reducing wear on the outer surface of the hose 10. The gear ring 322 and the outer wrapping component 30 are rotated by the drive motor 328 and the drive gear 325. The above structure facilitates the disassembly and assembly of the outer wrapping component 30, the rotation drive component 32, and the end positioning component 31, realizing the rapid assembly and cleaning of the inner cleaning mechanism 3 and the hose 10.
